The Musical Exploration Of Isms - 1770 Words

Introduction Mickey Hart once said, â€Å"Life is about rhythm. We vibrate, our hearts are pumping blood, we are a rhythm machine, that’s what we are.† Percussion is one of the oldest instrument families and has grown to a degree of vast importance in all forms of modern Western music. Namely, this is because of the incorporation of percussion into both academia and entertainment music. At first, percussion was introduced into Western Classical music during the Classical period, as a means of getting exotic and unusual sounds for composers; however, the twentieth century works brought a unique gravitation to percussion. Twentieth century composers, such as Edgar Varese and John Cage, helped pave a way for an era of music history marked by†¦show more content†¦The Janissary instruments find their roots in the Turkish military bands of the Ottoman Empire. The term Janissary refers to the Turkish Yeà ±i-à §eri, or â€Å"new troops†. Sultan Orkhan I, of the Ottoman E mpire, created The Janissaries, but his successor, Murad I, officially established the corps circa 1360’s CE. Furthermore, they were originally an elite corps of troops made up of the Sultan’s loyal slaves. The corps eventually picked up the use of military bands, which was a highly esteemed military tradition. These military bands are even documented in a 1237 CE manuscript inscribed during the Crusades, which depicts two â€Å"long trumpets† and a pair of mounted â€Å"kettledrums† with battle flags and standards. The date of this manuscript indicates the Arabic and Persian heritages of one of the major instruments in the Janissary classification, the Timpani. In addition, the Ottoman Expansionism throughout the 1600’s gave the Western world a large amount of exposure to the Turkish military band music and instruments. Countless militarily effective instruments were carried into Western armies, such as the Cavalry Kettledrums, or Timpani.

History of Management Free Essays

Without any doubt, the question of work, roles and skills of a manager gets a mixed response. Some believe that these features are the shared by managers all over the world, while others maintain that there are significant differences in management of different countries that have given rise to such a notion and a process as the intercultural management. Which one of the above-stated arguments has an element of truth and could they be both regarded as authentic? First of all it cannot be denied that the science of management has a long history and perhaps all modern mangers employ principles and theories that have been introduced earlier. We will write a custom essay sample on History of Management or any similar topic only for you Order Now To start with, it was the Industrial Revolution that established big business and created the need for professional leaders. Furthermore, years of military and church rule added management models and terminology that are widely used today. Let us only recall Max Weber’s bureaucratic theory or that of Frederic Taylor who is commonly regarded the Father of Scientific Management and proposed some ways of increasing workers’ productivity. On the basis of his research at Bethlehem Steel Company (Pittsburgh) he drew conclusions that the job can be split into minute parts and its performance can be improved by timing performance of each part separately. Furthermore, he suggested rest periods of special interval and duration and a differential pay scale that can be found in the practice of today’s managers (1). The famous method of overlapping tasks during the period of working day in order to avoid workers becoming tired easily was offered by Henry Gantt and displayed in the form of his ‘the Gantt chart’. Though not all of the managers may know the name of inventor of this tenet, but, for sure, most of them are acquainted with its expression and benefits it can provide. Moreover, it was Gantt who stressed the significance of the leadership and management qualities and skills for creating successful industrial organizations. The man who is dubbed as the Father of Modern Management is Henri Fayol, a French industrialist who developed a framework for studying management and wrote General and Industrial Management (1). He distinguished five functions of managers, such as: planning, organizing, commanding, coordinating, and controlling. As we see, all theorists and pioneers of management theory originated from various countries (England, France, United States, etc. ); however this did not impede the principles they have set out from becoming universal. Times are changing and so are doing the people but some essential things and useful hints are immortal and not subject to ageing. Let us take a closer look into the work of a manager disregard of the geographical location of his working place and language he speaks. Nobody would argue that the better we understand the management role; the better it will be performed and more qualitative services will be provided. Some people wrongly consider managers to be emotionless and cold fish and claim something like: â€Å"managers see work as something that must be done or tolerated,† â€Å"management focuses attention on procedure,† and â€Å"management sees the world as relatively black and white† (2, 2005:25). Yet, from our point of view, such standpoint is biased and far from being impartial. One should keep in mind that managers are also humans but the best among them have that gift for organizing and feel themselves capable of being at the head of other people and controlling not only their work but their lives in a way. Nevertheless, the manager’s work is not restricted to the above-mentioned issues only. Putting it by words of Carter McNamara, MBA, PhD, leadership is just one of the numerous facets of management, â€Å"just one of the many assets a successful manager must possess† (3). Therefore, it would be easier to determine the aim of a manager, which can be expressed as maximizing the output of his company with the help of effective administrative measures. This brings us to the definition of management itself that for short can be rendered as â€Å"the process of attaining organizational goals in an effective and efficient manner through planning, organizing, controlling, and directing organizational resources† (2). Therefore, any manager must undertake the already mentioned above functions: ? organizing ? planning ? commanding ? coordinating ? controlling Note, that leadership is covered by the single function of controlling. Planning comprises development of company strategies and goals. To put it differently, on this stage a manager has to define the direction of his business and some milestones to be taken into account. Moreover, planning involves also defining budget and plans of operation, i. e. methods of achieving previously fixed goals. In brief, on the phase of planning a manager proves to be a good forecaster capable of determining the far-reaching objectives. The following function and stage is organizing, which means right people on the right working places. In other words, this function presupposes that a manager must objectively consider knowledge and skills of his employees and offer them jobs that are most appropriate. Remarkably that some theorists of management call this function as â€Å"staffing† but to our mind, this notion is an element of organizing. Admittedly that â€Å"given the high levels of discretion enjoyed by knowledge workers, managers’ decisions over work distribution, content and resources become more critical for commitment and knowledge creation† (4, 2005:383-424). To sum up, organizing function covers establishing superior/subordinate relationships, as well as determining the scope of staff’s obligations and responsibilities. The ‘controlling’ function means checking that work is carried out in a proper way and funds are spent with regard to their purpose. The coordinating function covers training, team building, etc. and refers mainly to work with human resources, but not the production process. It should be added that effective managers should be good communicators and analysts. They should â€Å"have guts† to resist constant stress and be able to operate under unfavorable conditions. Furthermore, managers are responsible for friendly environment within a company, which engages problem-combating, settling conflicts, searching for best solutions, etc. What is more they should be assertive enough to bring forward their ideas and convince the opponents to give preference to their views. Still, that does not mean that all managers should be inborn leaders, whatever. Even more, as J. P. Kotter wrote in his 1991 â€Å"The Best of the Harvard Business Review† article, What Leaders Really Do: â€Å"Leadership is different from management, but not for the reason most people think. Leadership isn’t mystical and mysterious. It has nothing to do with having charisma or other exotic personality traits. It’s not the province of a chosen few. Nor is leadership necessarily better than management or a replacement for it. Rather, leadership and management are two distinctive and complementary activities. Both are necessary for success in an increasingly complex and volatile business environment† (5, 1991:26). However, in spite of the fact that there are some common features of manager work found in different countries and irrespective of borders, such as the key principles of management in a whole and functions of managers, it has been stated above that managers are the same people. Consequently, their cultural and personal peculiarities are reflected on their work. The former has even given rise to the completely new theory – intercultural management. The most significant factors that have enabled the emergence of this theory are the following: continuous globalization of economy and merge of businesses, establishment of joint ventures, foreign representative offices, etc. As a result, people started to pay more attention to the intercultural diversity of managing styles and traditions along with all-nation values and convictions. Should to go, when in Rome, do as the Romans do, but in order to comply with this rule one should know it. Notably, that in her article in the Financial Times by Elisabeth Marx titled ‘Shock of the alien can sink a merger’, for example, it was mentioned that â€Å"Research on cross-border acquisitions has shown that differences in management style (particularly in attitudes towards risk) have a negative effect on company performance. Sadly, very few companies consider the softer, cultural factors of mergers, which may be a significant contributor to their subsequent failures. Far too few companies even begin to consider the effects on staff or the human implication of a merger†. Furthermore, the article goes on to manifest that â€Å"it is easy to end up in a situation where the whole is worth less than the sum of its two parts†. Hence, the reasonable solution here may consist in following the statement and credo: â€Å"Managers’ first task is to conduct more extensive business analysis before taking the decision to merge. In addition to carrying out traditional financial and commercial due diligence, they should complete a thorough examination of the cultural compatibility of the parties involved† (6, 2005:2). The same can be applied to all spheres where business is conducted and companies in any country. Yert, the most frequent use of intercultural management tenet is observed within such association as, for instance, international markets, by merging with foreign companies, projects involving multi-cultural teams, international negotiations and so on, and so forth. Other supporting the intercultural management view theories are three well-known analyses of intercultural management by Edward Hall, Geert Hofstede and Philippe d’Iribarne that illustrate the differences between American and French management styles (7). Citing Edward T. Hall, intercultural differences in communication are based on the context, on time and on space: â€Å"Understanding between people results from the combination of information and its context. Some cultures have a rich context (close links between people, high level of the unspoken/unsaid): these cultures are highly † implicit†; other cultures valuing communication only when it is very clear in itself are said to be † explicit † (7). This can be exemplified by the French dislike of clearing procedures or by their creativity and flexibility, American productivity and utilitarianism etc (8, 2003:1333-1349). To sum up, there are common features that can be found among managers all over the world. Managers employ experience of earlier generations as well as coin modern ones. Today, theorists of management clearly define functions and goals of managing work and scope of their responsibilities and obligations. However, on the other hand, it remains disputable wither work of a manager is the same in different countries. Quite to the contrary, the intercultural management theory declares that every nation has its own management style that should be taken into account when conducting international negotiations and making business with foreign countries. The majority of businessmen can no longer escape the necessity to purchase, sell or communicate and work with people from different cultures and thus with different traditions and convictions. And we are strongly sure that our future is multinational one! Bibliography 1. History of Management.

Purchasing Management And Operation of Zara †MyAssignmenthelp.com

Question: Discuss about the Purchasing Management of Zara. Answer: Introduction Purchase management is direct and costs benefit business expansion that needs legitimate planning and preparation for the acceleration of business. Purchasing management pushes the organization to the greater opportunity and evaluates the situation for achieving a long-term goal. Purchase management needs to get focus about the strategies and concepts of marketing so that the involvement of cost they deliver for the product will be regained with some, thus their business expansion upgrades a bit. Purchasing management or managers have to understand the internal organizational task and external collaboration task. In these two forms of the task, managers have to validate the necessary requirement of the company and have to define the purchasing strategy to make join activities and develop the supply chain. Zara is one of the best fashion brands retailing house which produces the quality product and has gained the customer trust and belief. Zara is the third largest retail brand in the World. Zara has 2169 stores in all over the world and has gained the revenue of $15.9 billion as per the report of 2016. Zara has accumulated with men and women clothing and now they are introducing the kid's sections as well named as Zara Kids. Zara has produced 450 million items per year and all their products are based on the contemporary customer trends (Zara.com/sg 2017). Zara has launched 12,000 new designs in every year and they have the policy of zero advertising. Instead of advertising the company prefers to open a new store from the percentage of revenue they have gained through the process. Zara aims to develop new design instead of copy from the other. Zara has no vendors thus they used to sell their commodities from their own stores. As the company manufacturing price is considered only thus they maintain a low cost while selling the product (See-To Ho, 2014). Zara has the competitors like Hennes and Mauritz, GAP and Mark and Spencer. All these are reputed brand and they have a different base too. As the currency fluctuation is there in European market thus company may have tagged some high price that decreases their sales growth. Supply chain management and affordable purchase costing are the major issues that impact on the growth and sales of Zara. Supplier Selection Criteria A supplier selection criterion is a strategic decision that accomplishes companys growth for executing the objectives of the company on a long-term basis at a low risk. The organizational resources must have the conventional impact over the supply chain so that proper supply can be provided by the parent company in any adverse situation. this may engross the structure of the company as well as infuse the characters of their belongings (Uhl et al. 2017). In case of Zara, they have their own resources and all these made from their parent company thus they have a strong supply chain, they do not have any vendors thus the product they have produced has been distributed to all their stores for selling. Products are in affordable rate as there is no retailer or franchises intervention. There are two types of sourcing are noticed like single sourcing and multiple sourcing. In case of single sourcing, the production method is linear, where the products are depending on the customer judgments (Wengang Suicheng, 2015). It has a cost ratio too which provide the financial information about the marketing structure of the product. In case of multi-sourcing, the goal operating programming and mixed integer programming are the main formulation of process handling. There is a maintained structure of supplier selection where performance assessment, human resource, quality system assessment, manufacturing, business criteria, information technology all these are associated with the development of the company (van et al. 2015). There is a standard certification that has to be taken and maintained by the organization which is different from the countrys perspective. Thus the trend of business and the expansion of it depend on the supplier selection processing of that country. Quality of the product, environmental issues, customer response, revenue generation, place selection all these important aspects of establishing or enhancing the business market (Wee et al. 2014). The effective approach of suppliers selection method is important as well as relevant for the improvement of the organization. The organization needs to revise their screening process. In case of Zara, the quality of the product should be maintained so that the screening can be done in an effective way (Monczka et al. 2015). Another important aspect that needs to shed light on is the specification that needed by the customer. In case of Zara, the quality and product specification and the demand of the customer for the better design and apparels are the main and primary concern for the company. Creating a Professional supply base is important, in case of Zara their cohort and criticizer are so qualified and they impose such suggestions that ultimately engross the quality of resourcing. As their source is their own production house, hence those inputs are making a change as the production has been going on throughout the year (Wiengarten et al. 2017). Systematic supplier selection and method of inculpating the process of Zara has given a blend of Formation, design, length, color, style, fabric, material, texture which make customer-centric business. Purchasing cost and market analysis In case of Zara, the products they deliver to their customer are affordable in price, catchy in texture and color and have the touch of innovation within it. These are the purchasing requirement for a customer and that engage the cost-effectiveness within for the organization. Delivery time analysis is another cost related issue that customer has the concern. This is all about the more production in less amount of investment and makes engage more gain in terms of financial assistance. There are certain costing effects that influenced the business scenario and make a traditional approach to the customer as well as the world. There is a different analyzing system that makes a mark on the actual cost price of the product is. Cost is not being stopped there and that emphasis on the cost analysis structure (Schniederjans, Cao Triche, 2013). Ordering a large item of goods make delivered into this section where the cost analysis is being implemented where a huge amount of dealing in busine ss going on. In case of Zara the product analysis and their culture determine the quality and brand they deliver to the customer hence they have these amount of potential to mitigate the cost-effective as well. Considering the fact of optimum future of the business it is essential to understand the inventory designed those products proceed by a retail company, become an eye soothing and exiting one (Sirgy, 2015). In this kind of case, a deadline of delivery must be maintained for the inventor's end, so that customers have the belief and trust in the organization. Purchasing cost is a simple arrangement that an organization or investor pays for a particular product and that has become the investors cost (Leppelt et al. 2013). The investor has to sell the product with a major calculation of gain or loss when the product has been sold. If investor sold it out with higher prices, gain some extra amount if not then inventor could get confront of loss. Careful control and inventory needs are important for the maintaining behavior of the customer, in each case the cost affectivity is in an engagement. Activity-based costing, actual cost system, and conception and appraisal cost are in for the company like Zara where they have to put their brainstorm and make an innovation that needs those extra costs. Purchase costing can be affected by a suitable use of centralized purchasing. The procurement of saving and appropriate strategy needs to implement for the proper purchasing cycle. The involvement of obtaining the business and making use of their stores is the legitimate outsourcing and analyzing the process (Kim Choi, 2015). Short-term goals can be enriched and companies need to concentrate on their entire principle of marketing and business attire. The supplier optimization and the required quality service must be enhanced as the customer can get the product with affordable price rates. The total quality method may enrich the best purchasing practice that impacted on the customer preference and quality (Patel, Wise DelGaudio, 2017). Impact of information and Communication technology In case of Zara, Cloud computing has been used. As they are not giving their advertisement in media devices thus they want to make a streamlined channel and use ERP for their promotional purposes. The company has implemented the process so that channel marketing and web marketing can enhance. The underscore ERP solution provides more acrimony and sheds light on the resource planning of Zara. Information and communication technology is a rending service that incorporates more justification in business. Business can be enhanced by the effective use of the technology thus any acceleration that business wants can be viable by that technological assistance (Wagner Bode, 2014). There are numerous advantages that assured the disseminate information about the company. In this globalized world, businesses are based on multiple parameters. Networking is one of those where mass promotions and advancement of a product is being seen through the device. In use of cloud computing business model in novations and fashion trends and collection of innovates can be done by the customized handle held by the computer (Wilhelm et al. 2016). The execution of their IT infrastructure and real-time decision making have imposed the proper maintaining of their fame and extend their market in the globalized arena. Impact of Information and Communication Technology (ICT) and the development of strategies are the important attributes that presented by the company to produce more value and information to their customers. Effective use of communication for enhancement of business and the traditional inclusion of advertisement through television, newspaper, and magazines are also there for getting a better increase in business (Li, 2017). Zara is one of the biggest retail brands whose purchasing management is engrossed by the effect of critical inputs of customer belief and trust. The innovation like Digital Assistance Styling Shopper is a process where the customer can take a look at the material and innovators define the product quality by the communication process with customers (Tuta et al. 2014). This is the visual audio process where the use of mobile or tabular device people can connect any of the Zara executives and ask any query like face to face and the executive delivers all the probable answer and demonstrate the product as well as try to impress the customer but that process. If the customers like the product they can buy that instantly and will give the payment through a card. Zara service executive will be delivered the product within 24 hours at the customer residence. Conclusion Therefore, the report can be concluded that purchase management and the operational aspect of the purchasing enhance the supply chain management and provide extra value on purchasing cost with the effective use of information and communication technology. The process where the innovator invented products and customers will take the product; this will create the bonding of belief. In case of Zara, the quality they maintained for years is the best. They have numerous outlets and they share good business activity to their customers. The product quality, minimized cost and enhanced technical assistance provide a validating performance so that buyer-supplier relationship can be sustained. In comparison with other retail companies cost-effectiveness and supply market distribution play a great role to make proper importance to the adequate level of sharing the relationship with a customer. The performance of Zara in this globalized market is brilliant as their service, products, and quality is the classic in their part so that makes enhancement of their business.

The Bible Essay Research Paper God tiptoes free essay sample

The Bible Essay, Research Paper God tiptoes and dances upon a yarn every bit thin as fishing line, chat uping with being judged in two utmost manners. On one side you have him being a cruel and malicious divinity that inflicts penalties onto unsuspicious and unworthy victims. The other side he could be looked upon as a humane and just Godhead, who punishes merely the deserving. Critics have read, reread, studied, and analyzed the Old Testament until they were blue in the face. Many have come up with the fact that God acts in contradictory ways. He will harness panic against those who have disobeyed him in parts of Genesis, Ezekiel, Exodus and Job ; however, he will expose the forgiving and benevolent side in the same books of the Old Testament. Lord Acton one time said, # 8220 ; Power corrupts, and absolute power corrupts absolutely. # 8221 ; God had absolute power over everything in the existence.

God did sometimes penalize those who did non merit it, moving unfeelingly toward his ain people in parts of the Old Testament. In the Book of Genesis there are some things that God does that makes him unfair and unjust. God created everything and when he was done, # 8220 ; God looked at everything he had made, and he found it really good. # 8221 ; ( Genesis, 1 ; 30 ) God made everything abundant for Adam and Even in the garden, except one thing. He instructed them non to eat from the Tree of Knowledge. In the tree God created a snake that tempted Adam and Eve to seek some fruit from the tree. They gave into the enticement from the snake and tried some fruit. If God created everything that was good so why would he hold created enticement that finally got Adam and Eve in problem? Furthermore why would God hold created a snake that would travel against his word and attempt to hold Adam and Eve get into a quandary? God acted below the belt to put a snake and enticement into the garden if he knew would merely take to jobs. Job was one of the most faithful and loyal retainers to God in all of the land. Job habitually worshiped God and avoided immoralities in any manner that he could. God was proud of him and of the manner in which he lived. God so got into an statement with Satan about the lone ground that he worships you so much is that he has everything. Take everything off and he will disinherit you to your face was Satan # 8217 ; s statement. God so without vacillation put Job through some of the most painful and barbarous intervention merely to turn out a point. He foremost had all of Job # 8217 ; s livestock either stolen or killed. Then he viciously wiped out his seven boies and three girls. That wasn # 8217 ; t adequate to turn out his point ; he so inflicted Job with terrible furuncles all over his organic structure. He made him endure in legion ways, God put Job through hurting that no 1 could conceive of. All for the simple fact that he could turn to Satan and state, # 8220 ; Told ya so! # 8221 ; Is that how God should move? Is it merely for him to bring down such a cruel and unworthy penalty onto one of his most loyal retainers, so he could out make Satan? He was mistreating his power, moving as an unfair and unjust Lord. In the Book of Exodus, God reined down his rage onto the people of Egypt moving in a really sadistic manner. The Lord wanted Moses to take the Hebrews off from Egyptian control. Moses had to so convert the Egyptian Pharaoh to allow the people go to idolize God. But, the Lord said, # 8220 ; I will do him obstinate, nevertheless, so that he will non allow the people go. # 8221 ; ( Exodus, 4 ; 21 ) So God so sent Egypt 10 horrific pestilences that wiped out about everything in the land. Some illustrations were that he sent locusts to destruct all the harvests, he gave all the farm animal plague so they died, he gave adult male and animal suppuration furuncles. His ten percent and concluding pestilence was the unkindest of the all. It was called decease of the first Born, # 8220 ; Every first-born in this land shall decease, from the first-born of the Pharaoh on the throne to the first-born of the slave-girl at the handmill, every bit good as all the first-born of the animals. # 8221 ; ( Exodus, 11 ; 5 ) God acted in such a desperate manner against the guiltless people of Egypt. Why would he butcher guiltless kids? It was his mistake that he made the Pharaoh obstinate and wouldn # 8217 ; t allow the Hebrews free. God inflicted penalty merely because he wanted to flex his musculuss and demo off how powerful he truly was. # 8220 ; Now is the clip to do justness a world for all of God # 8217 ; s kids, # 8221 ; said Martin Luther King Jr. God did punish people, but non viciously and inhumanely. There were parts in the Old Testament where people did disobey him, and were punished consequently. God sometimes didn’t even punish those who have sinned doing him non merely a merely Godhead but besides a sort one. In Genesis, the first book of the Bible, God did penalize. The people he punished though did something of importance to deserve censuring. God provided Adam and Eve with everything they could perchance conceive of. The Garden of Eden was plentiful and abundant. The lone direction he gave them was # 8220 ; ? You are free to eat from any of the trees of the garden except the tree of cognition? the minute you eat from it you are certainly doomed to die. # 8221 ; ( Genesis, 2:16-17 ) The Lord gave them direction every bit clear as twenty-four hours ; however, they ate from the tree. Alternatively of killing them instantly like he had antecedently stated he would make, he alternatively banished them from the garden for infinity. Traveling back on his original word he acted in a more indulgent manner. Cain and Abel was another narrative in the book of Genesis. Abel flourished in all that he did, but his brother, Cain, did non. Cain grew covetous and hostile of his Abel and one twenty-fou r hours took him into a field and slaughtered his brother. The Lord seeing this punished Cain, and made him a roamer for the balance of his life. At this clip God could hold been looked at as allowing Cain off the hook. If you compare his judgement of Cain to the Code of Hammurabi, Lord looks like he is allowing Cain off easy. In the Code of Hammurabi Cain would hold been killed no inquiries asked. Throughout parts of the book of Genesis the Godhead didn # 8217 ; t act in a revengeful and malicious manner, he was merely. The Book of Exodus offers some more proof that God wasn # 8217 ; t barbarous leader. Moses the 1 who he had chosen to be his leader was a liquidator. Moses had late, # 8220 ; ? slew the Egyptian and hid him in the sand. # 8221 ; ( Exodus, 2:12 ) The Lord did punish Moses in any manner possible, alternatively he chose him to be the leader of the Israelites. Again comparing this to the Code of Hammurabi, God would hold look really merciful and sort. After making this, the Lord turned to the Israelitess who were being viciously enslaved by the Egyptians. The Egyptians feared that the Hebrews were going # 8220 ; so legion and powerful # 8221 ; ( Exodus, 1:9 ) that they would catch them, so they enslaved the Hebrews. The Hebrews were being ill paid and being worked to the bone. Sing no manner out the Hebrews turned their hopes to God. God answered their calls for aid and sent pestilences to the Egyptians. He sent a sum of 10 pestilences to the Egyptians, which may look inordinate but the Egyptian Pharaoh was obstinate. After many of the pestilences the Pharaoh would lie to Moses and state them that he would allow his people be freed. Finally after the ten percent and concluding pestilence were the Hebrew people freed. God, so with the assistance of Moses, lead the Hebrews from Egypt to Sinai. The Lord chose a way through the desert for the Hebrews. When the Hebrews were in the desert they complained that they should hold been left in bondage, that it was better than hungering in the desert. God had merely released them from many old ages in bondage and they still weren # 8217 ; t satisfied. Alternatively of penalizing them for fundamentally ptyalizing in his face, he gave them what they asked for. If they needed staff of life he gave them staff of life, if they need H2O he provided it. The Lord was genuinely sort to the Hebrew people in legion ways. He was generous, sort and really humane in helping the Hebrews in their clip of demand. Throughout the Old Testament people disobey, doubted, and disrespected the Lord. God could merely take so much without bring downing penalty and justness onto those. The Lord did penalize many people, but those who he did penalize he had grounds for making so. In some cases he acted kindly and really generous. God in many parts of the Old Testament proved that he was a sort just swayer. Looking at God in a whole it is really hard to pull the line. Is he a revengeful Lord who punishes those who are undeserving or is he a sort merely divinity that is generous and understanding? There is non a right or a incorrect reply. Analyzing the Old Testament there is ample sums of cogent evidence for either side. It is really difficult to label him for good with being one over the other. All that is known is that belief in some divinity is non ephemeral, and the divinity that the people will go on to idolize will most probably be the sort generous Lord who is understanding and compassionate. Universally people will idolize the humane Lord because it gives them hope and a sense of goodness in their lives. It makes them experience of import in an facet, and that is something that everybody needs.

Mentality and Mindfulness Meanings

Mentality and Mindfulness Meanings Mentality and Mindfulness Meanings Mentality and Mindfulness Meanings By Mark Nichol Mental and its lexical relations, all pertaining to workings of the mind, as well as mind and words and phrases derived from that word, are listed and defined in this post. Mental Mental is descended from the Latin noun mens, meaning â€Å"mind.† It means â€Å"pertaining to the mind,† though it also has a slang connotation of being irrationally agitated, as when somebody is said to be â€Å"going mental.† Demented, likewise, is used both technically, to mean â€Å"mentally impaired,† and informally, to describe someone who is mentally unstable to a dangerous extent; dementia refers to cognitive impairment such as Alzheimer’s disease as well as to insanity. (Demential is a rare adjectival form.) Mentality means â€Å"intelligence,† though it more often refers subjectively to one’s way of thinking, as in the phrase â€Å"small-town mentality.† Mentation, meanwhile, is the process of thinking, and from this word science fiction author Frank Herbert derived Mentat, the name of a class of humans endowed with powerful cognitive abilities who take the place of computers in a future technophobic society. Mentalist is a dated term for a mind reader, someone who claims to be able to detect the thoughts of others. The noun mention can refer to a formal acknowledgment of recognition (as in a special mention or an honorable mention) or can denote calling attention to something; it serves as a verb for both meanings as well. A mentor is a person who provides guidance and advice to a person seeking to develop knowledge and skills. The term mentee was superfluously coined to describe the latter person; protà ©gà © serves that purpose well enough. To comment is to note or remark, or provide an explanation or illustration, or a critique or judgment; as a noun, the word refers to any such communication. (A commentary is a formal comment, usually expressed in speech or writing, though it may also refer metaphorically to a phenomenon that unintentionally speaks judgmentally to a state of affairs, as in â€Å"The unsightly litter is a sad commentary on the decline in the sense of personal responsibility.†) A memento is an object that prompts memories, such as a souvenir. (The Latin phrase â€Å"memento mori† means â€Å"reminder of mortality.†) A reminiscence is a recalled memory of an experience; to bring one to mind is to reminisce. The Latin forebear is seen in the Latin phrase â€Å"mens rea,† meaning â€Å"guilty mind,† and â€Å"mens sana in corpore sano,† which translates to â€Å"a sound mind in a sound body.† â€Å"Compos mentis,† meanwhile, means â€Å"of sound mind†; â€Å"non compos mentis† is a legal and medical term denoting the absence of a capacity to understand a situation. The ubiquitous suffix -ment, referring to a condition or state, an action or a location of an action, or an agent, means, or result of an action, is unrelated. Mind The word mind, from the Old English term gemynd, is cognate with mens as well as a href=http://monere, meaning â€Å"warning† (the source of monitor, admonish, and other words). The noun mind is often considered synonymous with brain, referring in general to an organism’s mental activities and capabilities, but the latter term denotes the organ that controls body functions, prompts physical responses, and facilitates learning; the mind is more accurately described as the part of a person that thinks, reasons, decides, perceives, and feels. Other senses include â€Å"memory† (as in â€Å"Keep that in mind†), â€Å"intention† (â€Å"Have you changed your mind?†), â€Å"opinion† (â€Å"She spoke her mind†), and â€Å"mood† (â€Å"I’m not in a good state of mind right now†). In addition, the word denotes a collective mental quality (as in â€Å"hive mind†) or a person of superior intelligence (â€Å"one of the great minds of our age†). Meanwhile, a minder is someone who attends to or oversees someone or something. To mind is to attend to, notice, or pay attention, or to obey or follow instructions, or to be careful or concerned. A reminder is a note about something to remember or a memory aid; the verb form is remind. The phrase â€Å"never mind† is employed to denote something less likely than something else (as in â€Å"I couldn’t even run a mile right now, never mind a marathon†) and is an idiom meaning â€Å"disregard what I said.† The use of Nevermind as the title of an album by the band Nirvana likely contributed to the frequent erroneous occurrence of the phrase as a closed compound, but any treatment of the term as one word other than in a colloquialism such as â€Å"It don’t make me no nevermind† (meaning â€Å"It doesn’t matter to me†) is an error. To be aware or attuned is to be mindful; the quality is mindfulness. To be mindless is to act without thinking or using critical-thinking skills; mindlessly is the adverbial form. Mind control is the practice of influencing someone’s beliefs, thoughts, and actions through hypnosis, propaganda, or other forms of persuasion or suggestion and, in fiction, manipulation of the person’s brain using some sort of technology. Meanwhile, a mind-set is a way of thinking. (Writers often treat this word as a closed compound, but dictionaries still favor the hyphenated form.) A mastermind is someone responsible for plotting or strategizing a scheme or a plan; the word is often used in the context of illicit or otherwise undesirable activities, as in â€Å"criminal mastermind.† One of limited intelligence or judgment is feebleminded (in the first sense only) or simpleminded. One who is forgetful is absentminded. Adverbial forms of these words are produced by adding the suffix -ly. Something that is astonishing, exciting, inspiring, puzzling, or otherwise stimulating or that has the potential to figuratively or literally alter one’s perception is referred to as mind-bending, mind-blowing, or mind-boggling. Such a phenomenon itself is called a mind-bender, mind-blower, or mind-boggler. Want to improve your English in five minutes a day?

The Battle of Midway - A Naval Analysis Research Paper

The Battle of Midway - A Naval Analysis - Research Paper Example In essence, this combat was at Midway atoll which was a mid-pacific naval base because of the high water tower visible in the area. In the past, Japan portrayed prowess over the US navy hence making them strike any where that they chose to without seeking consent from the US navy. However, The Battle of Midway created an equal platter for the two naval entities to take deemed offensiveness on one another. With these shallow facts presented, this essay will investigate the Battle of Midway and the significance it had on the historic past of the United States. Background information Primarily, Japan had strong convictions about eliminating US control over the greater Pacific region as a way of allowing themselves to create a larger Asian sphere for prosperity. For them, taking war to the Americans meant that Japan had demoralized them through defeat as a way of gaining upper recognition in the Pacific war. As part of their plan, Japan intended to lure US aircraft fleets into a trap tha t would allow them to be occupants of Midway on US soil. This action drew influence from the Doolittle Raid that made Japan cautious that facilitated the expansion of their perimeter defense area. However, the operation failed miserably because the US navy broke Japanese naval codes that provided information on the time and location of their deliberated attack 1. In essence, Japan intended to use Midway as a potential combat location that would have furthered attacks n Islands like Fiji and Samoa. In this regard, the forewarning enabled assisted the US in their setting up of a successful ambush of four out of six aircraft carriers as a vengeance plot for their own carriers attacked by Japan. Japanese battle plan As history would present it, the attack mission was under the able leadership of Admiral Yamamoto Isoroku that focused on winning the US over as they had done to Malaya, Phillipines, and Indonesia. However, there resulted internal wrangles between the Imperial Army and the N avy that led to delayed plans for the attack. In due time, the conflict achieved solutions as Yamamoto threatened to resign citing no cooperation from their counterparts. Finally, the two war agencies adopted his hatched plan to the latter. Essentially, Yamamoto was for the idea of destroying US aircraft forces as the country served as the primary hurdle to conquering the pacific. Moreover, the heightening of this concern drew influence from the Doolittle Raid of April 18, 1942 where US targets bombed Japanese cities. From this attack, the Japanese viewed American carriers as merciless threats as they were able to penetrate their territory with ease that tormented the Japanese psychologically. In his attack plan, Yamamoto intended to knock down defenses that existed in Midway and then establish a Japanese owned airbase there. The plan included an assault attack led by Deputy Admiral Nagumo Chuichi and his aircraft carrier from the North West. This would have weakened the forces of d efense in Midway to facilitate a strike on US warships. Next in the battle aircraft line would be a battleship with Admiral Yamamoto on-board who was to be the heavy Ferrier of gun powder essential for the war. Additionally, vice admiral Kondo Nobutake was to come from the southwestern and the western side whose role in the battle of Midway was to secure the area

How cultures use food Essay Example for Free

How cultures use food Essay 1. Outline the way different cultures use the value food? Out of the many different cultures present throughout the world, all value food in most similar ways. Most similarities can be struck between the availability of foods within their regions, specifically enviromental and seasonal ripening in the spring period. Food has become plentiful in Western civilisations over the past few decades, , due to the advances in agriculture allowing maximum growth and larger yields in the shortest amount of time (Chemgeneration 2011). This has also introduced interest into controversial genetically modified foods and the use of hybrid varieties of plants that have more desirable qualities. An example of this is Maize and certain potatoes that secrete a pesticide from the plant to ward of pests and insects, thus removing the need to use pesticides and chemicals (Chemgeneration 2011). Dr Rosalie McCauley (Development Office Department of Agriculture and Food WA, p1), obtained results that genetically modified foods haves been more increasingly used as the use of farmland increases exponentially at over 6% per year, seeing some 170.3 million hectares of GM foods being grown. In western society, there are a significant percentage of people either being overweight or obese, even Australia that has a population of approx 22 million (Australian Bureau of Statistics p1), with over 60% is considered over weight (ABS 2012, Australian Bureau of Statistics). Most overweight or obese individuals have and unhealthy relationship with food and it was theorised by Dr Carole Hungerford (Good Health in 21st Century) it can be considered ‘an addiction’. There is speculation as to why western society has such an addiction foods such as bread and milk, as we are the only species that drinks milk after weaning, especially that of another animal. Clinical studies and Medical Publications released by Dr J.L. Fortuna (PUBMED, 2010, p1) found clinical similarities for binge eating to that of drug dependences seeing a similar release of serotonin as with other drug dependencies. Though obesity is a prevalent condition around the world, numerous countries do not have the same obesity rates as western culture, some of this is likely to result in the way food is perceived by other cultures. Comparatively, in some cultures around the world, it is part of their culture to abstain from food for a short period of time. A more popularly known fasti ng is the Islamic undertaking of Ramadan where they fast during day light hours (Huda, 2009). Though in western cultures, people have a dislike to feel hungry, and can feel like they have fasted if they miss morning tea during a busy day at work. Numerous cultures throughout history have also used food as offering to their gods or deities to pray for health, or future harvests rain. Egyptian Pharaohs would be entombed with vast pots of food and spices to be used on their journey to the heavens. Some traditional practices continue even today such as the Korean Charye used to honour families ancestors, where special foods are prepared to during the Chuesoerk Ceremonies. The Chuesoerk (Korea.net, 2010) is a three day holiday to celebrate the good harvest received during the spring of that year. These cultural and religious uses for food are worldwide, and often not too distant from Christian practices of thanksgiving celebrated during the Christmas period. In conclusion, all cultures, no matter how distant or unique, have significant celebrations, events or relationships with a large role involving the use or lack of foods. The use of food to bring together communities and families is not dissimilar in almost all countries and demographics on earth; however the individuals use or overuse is not always healthy.

The current concepts of the western diet are based in the influence of proteins, carbohydrates, fats and vitamins and minerals (Whitney and Rolfes, 2013). Although we have come a long way with the introduction of multiculturalism some decades ago, for many western diet is still based around the proteins consisting of meats, predominantly red meat and chicken, carbohydrates with starchy root vegetables. This is often referred to as the ‘meat and three veg’ diet and the previous generations would have grown up with this as their diet staples as they where the majority of foods available for purchase or even grown themselves. With exception to the last 200 years, mankind has been involved in the seasonal use of foods and their diets where restricted by what was available at those times. Today there are vast changes in the way foods are produced to permit year round availability and the creation of food products that have previously been unavailable. Researchers at Bates Collage (Lewiston, ME, USA, 2013) believe that in the last 150 years since the invention of stones mills, the refining process of grain to create white flour, is now a consistent staple within the western diet. It was noted that this is a considerable source of carbohydrates and the cultures that had not encountered this food type previously began to show Heart Disease, Type 2 diabetes and stroke. These are all ailments that had been previously unseen in those areas. Additionally, the belief of receiving good value for money has become one of the most influential concepts and reasoning behind the purchase of processed food in recent times. The perception to receive the best meal, to be filling, quickly and well priced has seen the fast food chain market turn into a billion dollar industry (B.A. Swinburne, 2004). Anna Hodgekiss (U.S. daily Mail editor) explains that the over indulgence of these highly fatty foods have been  linked to short life spans and arrays of health problems. Even with the warnings and proven heath problems that arise, some families can become dependent on foods that are considered â€Å"value for money†. In conclusion, the general concepts to achieve the main food groups are relevant and understood but poorly enacted. The ease and availability of cheap fast food and highly refined products, that arrive ready to eat, are becoming preferential over the more time consuming cooking of foods from the local supermarket.

Discuss the comparative issues between man and nature? Nature is the world surrounding us, and it is the term we use to describe anything that happens which is out of our control. Such as natural disasters like cyclones, floods and drought. So considering this nature can not only be seen as a friend, but also as an enemy. Man desires to control nature by synthetic, mechanic and industrial plans. Synthetic and Natural medicines desire the same outcomes, of long life and good heath, but the methods to achieve it could not be any more different. Whether it is derived by numerous chemical processes or used in the original form it is found, nature made and manmade are vastly different especially when it comes to health and healing. Some cultures rely almost completely on nature to provide their basic needs such as water, food, shelter and even medicine. Though considered bland and not in line with the â€Å"perfect diet† (Health Schools Australia notes), the health benefits and improved health conditions are  achieved without the use of synthetic medicine, where as Western Diet, requires supplement by manmade medicines. This reliance on the local flora and fauna to provide all essentials and life improving aspects is not a new belief and is understood worldwide, but has been partially replaced by Western perception of that health can only be achieved by Pharmaceutical (Crigger NJ). The perception that health and food are separate and not interrelated because ‘man’ has created medicines that are better than those extracted from the ‘nature’ like Tibetans and non western cultures. In contrast, Western society has adopted that the scientific basis behind the synthetic production of therapeutic medicines is the only medical way to treat disease and illness. Today, it appears the practice of non synthetic medicinal applications is mostly centric to non western cultures. The â€Å"Perfect Diet’’ is deemed as a one shoe fits all remedy for the correct eating and dietary requirements for modern people. Where if we look at the diets of other cultures, such as the Hunza diet or Mediterranean Diet, where the majority of the population has a life expectancy significantly higher than that of the Western counterparts may have something to do with the foods that differ to that of the â€Å"Perfect Western Diet†(Diet Choices, 2014 and Trichopoula, A). One key reason is believed to be the Hunza population in the Himalayas consume more than 200% (Dainca Collins, 2011) of the B17 (also known as Amygdalan) than their western counter parts. This is likely due to the Hunza eating the seeds of all fruits, which is something that is often discarded within western society. Christina Larner (Body and Soul) has identified that Apricot se eds contain the largest concentrations of B17, and has been used a cancer treatment in modern times. However the same seeds are alleged to have caused Cyanidic acid when consumed to excessive quantities, but cases of cyanide toxicity are rare (Christina Larner). In conclusion, man created medicines for health and longevity are proven to be available in the natural world around us. Public perception provides the strongest reasons why man made pharmaceuticals are the main stream choice for western society, where as the isolated communities use the world around them to treat their ailments. 1.Whitney, E and Rolfes, S.

Australia’s culinary heritage has expanded greatly over the last 100 years with numerous population demographics immigrating to Australia. We have observed cultural and culinary delights flood our markets, restaurants and kitchens with sights, smells and aromas from around the world. Many years ago these would have been deemed exotic and bizarre, but are now considered almost staple additions to the average household pantry. Fifty years ago, within our Grandmothers pantry, our available food selections were significantly limited in spices and rare/exotic foods that are now considered normal place. Meat and three veg meals of starchy root vegetables and heavy protein meats where the staple of the diet during those times. It is argued (Potatoes SA) that these staples popularity on Australian kitchen tables where due to the European based settlers focusing on farming practices for this produce over the last 100 years. Pliner and Hoden (cit. Evaluation of food choice behaviours, p 20) stated it was more to do with the neophobic attitude towards foreign foods due to the â€Å"unfamiliarity of foods† that limited the adventurous mindset to the evolving culinary scene. In either case, only since World War 2 did the appearance of multicultural foods and diets start to intermix. One of the most popular entries into our diets is the highly regarded Mediterranean diet consisting of uncooked fresh whole vegetables, whole grains and some fish and seafood but minimal meat. That compared to the past diets of root based vegetables that where often boiled or baked, and argued to lose most of its natural vitamins and minerals during the cooking process, especially seen with water soluble vitamins (Better Health Channel). The high use of tomatoes within the Mediterranean diet, which contain large amounts of the antioxidant lycopene and that is believed to have anti-tumour properties to relieve cancers  particularly in the prostate and multiple-myeloma (Tonia Reinhard, p44-45). Additionally, the vibrant coloured vegetables that contain high amounts of VIT A and C such as Capsicums, Spinach, green leafy vegetables. VIT A is required for vision, the immune system and as an antioxidant. Dr Carole Hungerford (Good health in 21st century, p160) identifies that night blindness is a symptom of VIT A deficiency. Even the fats used are considered healthier with the Olives and olive oil as the principle source of fat. Tonia Reinhard states that Olive oil contains the richest source of mono unsaturated fatty acids, being 77% mono-unsaturated and 14% saturated, this is attributed as to why it helps to prevent cardiovascular disease. In conclusion, the diversity of foods that have spread across the world is bring ing the many health benefits to many. As the world continues to expand and new ideas and foods are embraced, soon the healing and healthy properties of those unique diets will improve the health and well being across the globe. 1.Potatoes South Australia, 2013, Elder House, Adelaide, SA, viewed 15 January 2014 2.Online Thesis – Roininen, Katariina, 2001, Evaluation of food choice behaviour: Development and Validation of health and taste attitude scales, visited 15 January 2014 3.Better Health Channel, July 2013, Victorian Government, viewed 15 January 2014 4.Hungerford, Dr Carole, 2008, Good health in the 21st century, Revised Edition, Scribe, Victoria. 5.Reinhard, Tonia, (2010), SUPERFOODS The Healthiest Foods on the Planet, Cove Press, NSW 5) The future of nutrition In the past and even in some places still today, nutrition has not play a conscious role in conventional medicine, as the focus has and always seems to be about treating disease not the cause. Nutrition based medicine has been labelled with a stigma as ‘alternative’ or new age and not given the same attention as the newest drug on the market. Recently have we begun to see some changes within the health care system which offers clients a  natural alternative to pharmaceuticals. This has began a movement known as Integrative Medicine (OSHER, 2012), where the approach is about taking the best from conventional and alternative medicine and combining them. This combination of practices is reinforcing the tenants of prevention rather than cure, which follows the old adage that â€Å"an ounce of prevention is better than a pound of cure†. We are already seeing this revolutionary ideal take off with the emergence of integrative clinics now established in some major citi es, and where patients even seek further information from their GP on what additional alternative treatments are available for their ailments (Mike Adams, 2005). This wider social consciousness towards natural alternatives is perhaps due to the increased marketing of nutritional supplements within media (Mike Adams, 2005). These messages are making people more curious about their health and what they can do to improve it. In addition, we are seeing nutritional products such as ‘Inner Health Plus’ a pro-biotic supplement, is sometimes prescribed to patients following a course of antibiotics. This behaviour by GP’s is demonstrating a small but important step to the medical and health organisations towards the evolution of nutritional medicine. The popularity of supplements and their advertised health benefits has propelled the sale of many nutritional products, especially Omega 3 supplements derived from fish oil or krill oil (Lisa Schofield, 2013). Omega 3 that is naturally occurring within deep ocean fish species has been proven to be beneficial for arthritis suffers, for heart health, and general wellbeing (Whitney, 2013, pg 161.). Dr Hungerford (Hungerford, 2008) tells us that until recent times, animals who do not manufacture their own omega 3 would have had to eat plants which contain omega 3’s for protection against the cold and other health benefits. However, as we domesticated animals, kept them warm in barns, and fed them the food we grew; the animals did not require as much omega 3 in order to survive. This man made change is a potential reason is why fish still remains one of the best sources of omega 3, as the majority of fish that we consume are wild. (Hungerford, 2008 pg. 6-7). In summary, the stigma of nutritional based medicine is slowly being lifted as media, mainstream medicine and health care practitioners inculcate these practices into their professions. Today, more than ever, people have access to the information and products that can be utilised to improve their health, wellbeing and  diets. As the message becomes clearer and better understood, it is likely that the stigma will be removed completely and nutritionists will be given the same renowned as the doctors and medical professionals that share the same vision for long and healthy life for all. 1.Osher Centre for Integrative Medicine, University of California, 2012, CA, USA, viewed 17 Jan 2014 2.Adams, Mike, 24 July 2005, Natural News, viewed 17 Jan 2014 3.Hungerford, Dr Carole, 2008, Good health in the 21st century, Revised Edition, Scribe, Victoria 4.Schofield, Lisa, 09 Sep 2013, Nutraceuticals World, viewed 17 January 2014 5.Whitney, E and Rolfes, S.

Internetworking End-to-End Requirements Essay

– Hence such characteristics as: performance, reliability, scalability, mobility, and QoS of DS are impacted by the underlying network technology and the OS ? Principles of computer networking – Every network has: ? An architecture or layers of protocols ? Packet switching for communication ? Route selection and data streaming ? Comm Subsystems (network technologies rest on): – Transmission media: wires, cables, fiber, wireless (sat, IR, RF, mwave) – Hardware devices: routers, switches, bridges, hubs, repeaters, network interfaces/card/transceivers. – Software components: protocol stacks, comm handlers/drivers, OS primitives, network-focus APIs ? Hosts – The computers and end-devices that use the comm subsystem – Subnet: A single cluster or collection of nodes, which reach each other on the same physical medium and capable of routing outgoing and incoming messages – The Internet is a collection of several subnets (or intranets) ? Networking issues for distributed systems – Initial requirements for DS applications: ftp, rlogin, email, newsgroup – Subsequent generation of DS applics. : on-line shared resources. – Current requirements: performance, reliability, scalability, mobility, security, QoS, multicasting ? Performance – Key: time to deliver unit(s) of messages between a pair of interconnected computers/devices – point-to-point latency (delay) from sending out of outgoing-buffer and receiving into incoming-buffer. Usually due to software overheads, traffic load, and path selection – Data transfer/bit rate: speed of data transfer between 2 computers (bps). Usually due to physical properties of the medium. ? Message trans time = latency + length/bit-rate ? Bandwidth vs. bit-rate. – The total system bandwidth (volume of data sent and received in a unit time, e. g. , per sec. ) is a measure of its throughput – Bit rate or transfer rate is restricted to the medium’s ability to propagate individual bits/signals in a unit time – In most LANs, e. g. , Ethernet’s, when full transmission capacity is devoted to messaging (with little or no latency), then bandwidth and bit-rate are same in measure – Local memory vs network resources: ? Applications access to shared resources on same network usually under msec ? Applications access to local memory usually under msec (1000x faster)? However, for high speed network web-server, with caches, the access time is much faster (than local disk access due to hard disk latency) ? Scalability (Internet and DSs) – Future growth of computing nodes of Internet (hosts, switches) in 109’s (100’s of 106 hosts alone) – Requires substantial changes to routing and addressing schemes (more later! ) – Current traffic (load) on Internet approx. measured by the latencies (see www. mids. org), which seem to have reduced (with advances in medium and protocol types). – Future growth and sustainability depend on economies of use, charge rate, locality/placement of shared resource? Reliability – Failures are typically, not due to the physical medium, but at the end-end (at host levels) software (application-level), therefore, error detection/correction is at the level – Suggesting that the communication subsystem need not be error-free (made transparent/hidden to user) because reliability is somewhat guaranteed at the send/receiver ends (where errors may be caused by, e. g. , buffer overflow, clock drifts causing premature timeouts) ? Security – Most intranets are protected from external (Internet-wide) DSs by firewall. – A firewall protects all the resources of an organized from unlawful/malicious access by external users, and control/monitoring of use of resources outside the firewall – A firewall (bundle of security software and network hardware) runs on a gateway – the entry/exit point of the corporate intranet – A firewall is usually configured based on corporate security policy, and filters incoming and outgoing messages. – To go beyond firewalls, and grant access to world- or Internet-wide resources, end-to-end authentication, privacy, and security (Standards) are needed to allow DSs to function – E. g., techniques are Cryptographic and Authentication – usually implemented at a level above the communication subsystem – Virtual Private Network (VPN) security concept allows intranet-level protection of such features/devices as local routers and secure links to mobile devices ? Mobility – Need wireless to support portable computers and hand-held devices – Wireless links are susceptible to, e. g. , eavesdropping, distortions in medium, out-of-sight/range transmitters/receivers – Current addressing and routing schemes are based on ‘wired’ technologies, which have been adapted and, therefore, not perfect and need extensions? QoS (Quality of Service) – Meeting deadlines and user requirements in transmitting/processing streams of real-time multimedia data – E. g. , QoS requirements: guaranteed bandwidth, timely delivery or bounded latencies, or dynamic readjustments to requirements ? Multicasting – Most transmissions are point-to-point, but several involve one-to-many (either one-to-all – broadcast or selective broadcast – multicast) – Simply sending the same message from one node to several destinations is inefficient – Multicasting technique allows single transmission to multiple destination (simultaneously) by using special addressing scheme 3. Multimedia Transmission and Internetworking Heterogeneous Systems ? Types of Networks – LANs: (confined to smaller, typically, 2. 5km diameter spread) ? higher speed, single medium for interconnection (twisted pair, coax, opt), no routing within ‘segments’ – all point-to-point (from hub), inter-segment connections via switches/hubs, low latency, low error rate ? E. g. , Ethernet, token ring, slotted ring protocols, wired. (1) Ethernet: 1970 with bandwidth of 10Mbps, with extended versions of 100/1000Mbps, lacking latency and bandwidth QoS for DSs: (2) ATM – using frame cells and optical fills the gap but expensive for LAN, newer high-speed Ethernets offer improvement and cost-effective – MANs: (confined to extended, regional area, typically, up to 50km spread) ? Based on high-bandwidth copper and fiber optics for multimedia (audio/video/voice), ? E. g. , technologies: ATM, high-speed Ethernet (IEEE 802. 6 – protocols for MANs), DSL (digital subscriber line) using ATM switches to switch digitized voice over twisted pair @ 0. 25-6Mbps within 1. 5km, cable modem uses coax @ 1. 5Mpbs using analog signaling on TV networks and longer distances than DSL – WANs: (worldwide, lower speeds over sets of varying types of circuits with routers) ? High latency (due to switching and route searching) between 0. 1-0. 5s, signaling speed around 3x105km/s (bounds latency) plus propagation delay (round-trip) of about 0. 2s if using satellite/geostationary dishes; generally slower at 10-100kbps or best 1-2Mbps – Wireless: (connecting portable, wearable devices using access points) ? Common protocol – IEEE 802. 11 (a, b, and now g) (WaveLAN) @ 2-11Mbps (11g’s bandwidth near 54Mbps) over 150m creating a WLANs, some mobiles connected to fixed devices – printers, servers, palmtops to create a WPANs (wireless personal area networks) using IR links or low-powered Bluetooth radio network tech @ 1-2Mbps over 10m. ? Most mobile cell phones use Bluetooth tech. e. g. , European GSM standard and US, mostly, analog-based AMP cellular radio network, atop by CDPD – cellular digital packet data communication system, operating over wider areas at lower speed 9. 6-19. 2kbps.? Tiny screens of mobiles and wearables require a new WAP protocol – Internetworks ? Building open, extendible system for DSs, supporting network heterogeneity, multi-protocol system involving LANs, MANs, WLANs, connected by routers and gateways with layers of software for data and protocol conversions – creating a ‘virtual network’ using underlying physical networks ? E. g. , the Internet using TCP/IP (over several other physical protocols) – Comparisons ? Range of performance characteristics: ? Frequency and types of failures, when used for DS applics? Packet delivery/loss, duplicates (masked at TCP level to guarantee some reliability and transparency to DSs; but may use UDP – faster but less reliable and DS applic’s responsibility to guarantee reliability) Diagram 3. 2 Network Principles †¢ Packet Transmission †¢ Packet transmission superseded telephone/telegraph switched network †¢ Messages are packetized and packets are queued, buffered (in local storage), and transmitted when lines are available using asynchronous transmission protocol †¢ Data Streaming †¢ Multimedia data can’t be packetized due to unpredicted delays. AV data are streamed at higher frequency and bandwidth at continuous flow rate †¢ Delivery of multimedia data to its destination is time-critical / low latency – requiring end-to-end predefined route †¢ E. g. networks: ATM, IPv6 (next generation – will separate ‘steamed’ IP packets at network layer; and use RSVP (resource reserv. protocol) resource/bandwidth prealloc and RTP play-time/time-reqs (real-time transp protocol) at layers 3 & 1, respectively) to work ? Switching Schemes – 4 Kinds of switching methods typically used. – Broadcast – no switching logic, all nodes ‘see’ signals on circuits/cells (e.g. , Ethernet, wireless networks) – Circuit Switching – Interconnected segments of circuits via switches/exchange boxes, e. g. , POTS (Plain Old Telephone System) – Packet Switching – Developed as computing tech advanced with processors and storage spaces using store-and-forward algorithms and computers as switches. Packets are not sent instantaneously, routed on different links, reordered, may be lost, high latency (few msec – msecs). Extension to switch audio/video data brought integration of ‘digitized’ data for computer comm. , telephone services, TV, and radio broadcasting, teleconferencing. – Frame Relay – PS (not instantaneous, just an illusion! ), but FR, which integrates CS and PS techniques, streams smaller packets (53 byte-cells called frames) as bits at processing nodes. E. g. , ATM – Protocols – – Protocols – implemented as pairs of software modules in send/receive nodes, – Specify the sequence of messages for transmission – Specify the format of the data in the messages – Protocols Layers – layered architecture, following the OSI suite – packets are communicated as peer-to-peer transmission but effected vertically across layers by encapsulation method over a physical medium Protocols Suites – The 7-layered architecture of the ISO-OSI †¢ Each layer provides service to the layer above it and extends the service provided by the layer below it †¢ A complete set of protocol layers constitute a suite or stack †¢ Layering simplifies and generalizes the software interface definitions, but costly overhead due to encapsulations and protocol conversions Diagram 3. 3 4. Service Provider Management On the Internet, a management service provider (MSP) is a company that manages information technology services for other companies. For example, a company could hire an MSP to configure and administer its business computers and related systems on a continuing basis, saving the company. An MSP is a service provider that offers system and network management tools and expertise. An MSP typically has its own data center that runs advanced network management software such as HP OpenView or Tivoli. It uses these tools to actively monitor and provide reports on aspects of its customer’s networks, including communication links, network bandwidth, servers, and so on. The MSP may host the customer’s Web servers and application servers at its own site. The services provided by MSPs have been called â€Å"Web telemetry† services. The MSP Association defines MSPs as follows: Management Service Providers deliver information technology (IT) infrastructure management services to multiple customers over a network on a subscription basis. Like Application Service Providers (ASPs), Management Service Providers deliver services via networks that are billed to their clients on a recurring fee basis. Unlike ASPs, which deliver business applications to end users, MSPs deliver system management services to IT departments and other customers who manage their own technology assets. TriActive is an example of an MSP. It provides management and monitoring of PCs, servers, networks, and Web sites from its own NOC (network operations center), which is hosted by Exodus Communications. Exodus ensures that the NOC has fully redundant power, network connectivity, routing, and switching to ensure maximum reliability and integrity. A â€Å"microagent† interacts with customer systems to provide system management. The agent is lightweight and designed for use over the Internet. It acts as a universal agent invoking and managing other agents and programs as required for specific actions. The service is delivered via the Web through a secure Internet portal that lets customers view management information, based on their role in the organization. For example, CIOs can view overall management information while help desk technicians can check call queues, escalations, and open ticket status. Systems analysts can conduct asset inventories and view virus reporting. Objective Systems Integrators is another management service provider that provides software solutions for unified network, service application, and process management. OSI was recently acquired by Agilent Technologies. A list of other MSPs may be found at the MSP Association Web site. Web application and infrastructure monitoring and management have suddenly become critical, yet the tools to do them are lacking. Management service providers (MSP), the latest addition to the current slew of service providers, claim to offer products and services that will oversee your Web operations. Companies staking claims as early MSPs include Candle Corp. in Santa Monica, Calif. ; InteQ Corp. in Burlington, Mass. ; and Nuclio Corp. in Skokie, Ill. What makes MSPs distinctive is that their products and services are provided over the Internet on a subscription basis. That means â€Å"MSPs can achieve economies of scale that companies who license software cannot,† says Christopher Booth, head of technical operations at FreightWise Inc. , a Forth Worth, Texas-based online transportation exchange. Though he declined to say how much his company is paying to use Nuclio’s MSP, Booth did say that the service has been â€Å"very advantageous. † The cost savings that MSPs can pass on may help them catch on with corporate customers. Gartner Group Inc. in Stamford, Conn., estimates that the $90 million MSP market will balloon to more than $3. 25 billion by 2005. 5. Programmable/Cognitive Networks A key strength of the Internet has been to reduce the intelligence within the network to that required placed at strategic places within the network such as at administrative boundaries, or at locations where there is a large mismatch between bandwidth, or where the certain location specific services can be used. Others believe that the entire architecture should be rethought as a computational environment, in which everything can be programmed, and the entire network becomes active. The research in this area is aimed at discovering how viable it is to open up such elements of the communications architecture as the routing table. A fundamental question raised by both the active service and the active network approaches is how to ensure that the shared resource of the network remains safe and is protected from misbehaving programs. Programs can abuse the network by generating packet explosions and can abuse the shared processor by using all the memory and the processor cycles. Worse, they may subvert the working of correct programs so that they too break. If network programmability is going to be available to the application designers, we need to ensure that they do not break things by accident, let alone by intention. Traditional systems approaches to protection are based upon what a program should be able to do, then using runtime checks to ensure that the program doesn’t exceed these bounds. This leads to the sandbox model of protection, as used in Java and enhanced to provide protection for Active Networks. However, there are major problems with this approach. First, each runtime check reduces the performance of the system, increasing the overhead of each use of system resources. Second, it is very difficult to ensure that the protection mechanisms are correct, and cannot be subverted in any way. An alternative approach is to use compile time checks upon what the program is doing. This uses the type system to represent predicates about program functionality and if a program is well-typed, then it proves the program to obey the policies implemented in the type system. This approach has been used to allow users to run programs within the kernel as in Spin, and in protecting access to router functionality in the Switchware project. †¢ To provide a network programming language based on Internet `best effort’ communication. †¢ To provide scaleable high-level communication based on `remote spawn’ from which other communication can be built. †¢ To make use of types as safety properties, to ensure that the safety and security policies of the network are maintained. †¢ To rapidly prototype tools such as compilers and simulators in order to drive the development of the language by examples. Best-effort distributed programming In the Internet, an application transmits a packet, which is sent to the next router on the way to the destination. At this router, the arrival of the packet causes code to run, which calls other code dependent upon the fields in the header of the packet. This code may access and modify local state stored in the router and then copy or create one or more packets to be sent out from the router. These packets are then routed on output links depending upon the destination for each packet, and so on until the packets reach their destination, or are destroyed within the network for whatever reason. In our programming model, we have attempted to replicate this basic structure of packet transmission. In the Internet, the arrival of a packet initiates some thread of control which uses the data within the packet to decide upon the disposition of the packet. In our model, a packet becomes a thread of control, carrying the code to be run and the names or values of any data referenced within that code. When a thread arrives at a Safetynet-aware router or end system, the thread code is instantiated within the runtime and runs within a de_ned scheduling class. The thread of control may call other code to be run on its behalf. The other code is encapsulated within classes, which are either present in the router, or are dynamically loaded from elsewhere. Threads can spawn other threads, either locally or on the next hop to some destination. 6. Design of an Internetwork We will discuss about the networking especially the internetworking. In this case we will need to discuss some topics related with the Internet Infrastructure, Internet routing, domain name and address resolution, internet protocol and the applications. Internet Infrastructure: The Internet backbone is made up of many large networks which interconnect with each other. These large networks are known as Network Service Providers or Naps. Some of the large Naps are UUNet, Cerf Net, IBM, BBN Planet, Sprint Net, PSINet, as well as others. These networks peer with each other to exchange packet traffic. Each NSP is required to connect to three Network Access Points or NAPs. At the NAPs, packet traffic may jump from one NSP’s backbone to another NSP’s backbone. NSPs also interconnect at Metropolitan Area Exchanges or MAEs. MAEs serve the same purpose as the NAPs but are privately owned. NAPs were the original Internet interconnects points. Both NAPs and MAEs are referred to as Internet Exchange Points or IXs. NSPs also sell bandwidth to smaller networks, such as ISPs and smaller bandwidth providers. Below is a picture showing this hierarchical infrastructure. Diagram 4 This is not a true representation of an actual piece of the Internet. Diagram 4 is only meant to demonstrate how the NSPs could interconnect with each other and smaller ISPs. None of the physical network components are shown in Diagram 4 as they are in Diagram 3. This is because a single NSP’s backbone infrastructure is a complex drawing by itself. Most NSPs publish maps of their network infrastructure on their web sites and can be found easily. To draw an actual map of the Internet would be nearly impossible due to its size, complexity, and ever-changing structure. The Internet Routing Working: It is general phenomenon that No computer knows where any of the other computers are, and packets do not get sent to every computer. The information used to get packets to their destinations is contained in routing tables kept by each router connected to the Internet. The Routers are called the packet switches. A router is usually connected between networks to route packets between them. Each router knows about its sub-networks and which IP addresses they use. The router usually doesn’t know what IP addresses are ‘above’ it. Examine Diagram 5 below. The black boxes connecting the backbones are routers. The larger NSP backbones at the top are connected at a NAP. Under them are several sub-networks, and under them, more sub-networks. At the bottom are two local area networks with computers attached. Diagram 5 When a packet arrives at a router, the router examines the IP address put there by the IP protocol layer on the originating computer. The router checks its routing table. If the network containing the IP address is found, the packet is sent to that network. If the network containing the IP address is not found, then the router sends the packet on a default route, usually up the backbone hierarchy to the next router. Hopefully the next router will know where to send the packet. If it does not, again the packet is routed upwards until it reaches a NSP backbone. The routers connected to the NSP backbones hold the largest routing tables and here the packet will be routed to the correct backbone, where it will begin its journey ‘downward’ through smaller and smaller networks until it finds its destination. Domain Names and Address Resolution. But what if you don’t know the IP address of the computer you want to connect to? What if the you need to access a web server referred to as www. anothercomputer. com? How does your web browser know where on the Internet this computer lives? The answer to all these questions is the Domain Name Service or DNS. The DNS is a distributed database which keeps track of computer’s names and their corresponding IP addresses on the Internet. Many computers connected to the Internet host part of the DNS database and the software that allows others to access it. These computers are known as DNS servers. No DNS server contains the entire database; they only contain a subset of it. If a DNS server does not contain the domain name requested by another computer, the DNS server re-directs the requesting computer to another DNS server. Diagram 6 The Domain Name Service is structured as a hierarchy similar to the IP routing hierarchy. The computer requesting a name resolution will be re-directed ‘up’ the hierarchy until a DNS server is found that can resolve the domain name in the request. Figure 6 illustrates a portion of the hierarchy. At the top of the tree are the domain roots. Some of the older, more common domains are seen near the top. What is not shown are the multitude of DNS servers around the world which form the rest of the hierarchy? When an Internet connection is setup (e. g. for a LAN or Dial-Up Networking in Windows), one primary and one or more secondary DNS servers are usually specified as part of the installation. This way, any Internet applications that need domain name resolution will be able to function correctly. For example, when you enter a web address into your web browser, the browser first connects to your primary DNS server. After obtaining the IP address for the domain name you entered, the browser then connects to the target computer and requests the web page you wanted. The Disable DNS in Windows If you’re using Windows 95/NT and access the Internet, you may view your DNS server(s) and even disable them. If you use Dial-Up Networking: Open your Dial-Up Networking window (which can be found in Windows Explorer under your CD-ROM drive and above Network Neighborhood). Right click on your Internet connection and click Properties. Near the bottom of the connection properties window press the TCP/IP Settings†¦ button. If you have a permanent connection to the Internet: Right click on Network Neighborhood and click Properties. Click TCP/IP Properties. Select the DNS Configuration tab at the top. You should now be looking at your DNS servers’ IP addresses. Here you may disable DNS or set your DNS servers to 0. 0. 0. 0. (Write down your DNS servers’ IP addresses first. You will probably have to restart Windows as well. ) Now enter an address into your web browser. The browser won’t be able to resolve the domain name and you will probably get a nasty dialog box explaining that a DNS server couldn’t be found. However, if you enter the corresponding IP address instead of the domain name, the browser will be able to retrieve the desired web page. (Use ping to get the IP address prior to disabling DNS. ) Other Microsoft operating systems are similar. Internet protocols: As hinted to earlier in the section about protocol stacks, one may surmise that there are many protocols that are used on the Internet. This is true; there are many communication protocols required for the Internet to function. These include the TCP and IP protocols, routing protocols, medium access control protocols, application level protocols, etc. The following sections describe some of the more important and commonly used protocols on the Internet. Higher-level protocols are discussed first, followed by lower level protocols. Application Protocols: HTTP and the World Wide Web One of the most commonly used services on the Internet is the World Wide Web (WWW). The application protocol that makes the web work is Hypertext Transfer Protocol or HTTP. Do not confuse this with the Hypertext Markup Language (HTML). HTML is the language used to write web pages. HTTP is the protocol that web browsers and web servers use to communicate with each other over the Internet. It is an application level protocol because it sits on top of the TCP layer in the protocol stack and is used by specific applications to talk to one another. In this case the applications are web browsers and web servers. HTTP is a connectionless text based protocol. Clients (web browsers) send requests to web servers for web elements such as web pages and images. After the request is serviced by a server, the connection between client and server across the Internet is disconnected. A new connection must be made for each request. Most protocols are connection oriented. This means that the two computers communicating with each other keep the connection open over the Internet. HTTP does not however. Before an HTTP request can be made by a client, a new connection must be made to the server. When you type a URL into a web browser, this is what happens: If the URL contains a domain name, the browser first connects to a domain name server and retrieves the corresponding IP address for the web server. The web browser connects to the web server and sends an HTTP request (via the protocol stack) for the desired web page. The web server receives the request and checks for the desired page. If the page exists, the web server sends it. If the server cannot find the requested page, it will send an HTTP 404 error message. (404 mean ‘Page Not Found’ as anyone who has surfed the web probably knows. ) The web browser receives the page back and the connection is closed. The browser then parses through the page and looks for other page elements it needs to complete the web page. These usually include images, applets, etc. For each element needed, the browser makes additional connections and HTTP requests to the server for each element. When the browser has finished loading all images, applets, etc.the page will be completely loaded in the browser window. Retrieving a Web Page Using HTTP: Telnet is a remote terminal service used on the Internet. Its use has declined lately, but it is a very useful tool to study the Internet. In Windows find the default telnet program. It may be located in the Windows directory named telnet. exe. When opened, pull down the Terminal menu and select Preferences. In the preferences window, check Local Echo. (This is so you can see your HTTP request when you type it. ) Now pull down the Connection menu and select Remote System. Enter www. google. com for the Host Name and 80 for the Port. (Web servers usually listen on port 80 by default. ) Press Connect. Now type GET / HTTP/1. 0 And press Enter twice. This is a simple HTTP request to a web server for its root page. You should see a web page flash by and then a dialog box should pop up to tell you the connection was lost. If you’d like to save the retrieved page, turn on logging in the Telnet program. You may then browse through the web page and see the HTML that was used to write it. Most Internet protocols are specified by Internet documents known as a Request for Comments or RFCs. RFCs may be found at several locations on the Internet. See the Resources section below for appropriate URL’s. HTTP version 1. 0 is specified by RFC 1945. Application Protocols: SMTP and Electronic Mail: Another commonly used Internet service is electronic mail. E-mail uses an application level protocol called Simple Mail Transfer Protocol or SMTP. SMTP is also a text-based protocol, but unlike HTTP, SMTP is connection oriented. SMTP is also more complicated than HTTP. There are many more commands and considerations in SMTP than there are in HTTP. When you open your mail client to read your e-mail, this is what typically happens: The mail client (Netscape Mail, Lotus Notes, Microsoft Outlook, etc.) opens a connection to its default mail server. The mail server’s IP address or domain name is typically setup when the mail client is installed. The mail server will always transmit the first message to identify itself. The client will send an SMTP HELO command to which the server will respond with a 250 OK message. Depending on whether the client is checking mail, sending mail, etc. the appropriate SMTP commands will be sent to the server, which will respond accordingly. This request/response transaction will continue until the client sends an SMTP QUIT command. The server will then say goodbye and the connection will be closed. Transmission Control Protocol: Under the application layer in the protocol stack is the TCP layer. When applications open a connection to another computer on the Internet, the messages they send (using a specific application layer protocol) get passed down the stack to the TCP layer. TCP is responsible for routing application protocols to the correct application on the destination computer. To accomplish this, port numbers are used. Ports can be thought of as separate channels on each computer. For example, you can surf the web while reading e-mail. This is because these two applications (the web browser and the mail clien.
