Civilian Contractors on the Battlefield Essay Example | Topics and Well Written Essays - 750 words

Civilian Contractors on the Battlefield - Essay Example The following discussion is going to explore the ethical problems, whilst defining the actual position of a civilian contractor on the battlefield. Also it will consider the security problems in depending on civilian personnel, because there interest is in the monetary value of their service rather than the loyalty and security of a nation4. Therefore this may jeopardize the security of battle planning, because if civilian contractors are working on a business level then if the opposition offered a better business deal then these civilian contractors become a breach in the US military strategy5. In the first place the role of the civilian contractor can be seen as military personal as the Hague Convention of 1907 allows that other persons can be combatant in a time of war than just military personnel. Therefore under the Geneva Convention these individuals will be afforded the protections as prisoners of war. This means that on the ethical grounds of using contractors on the battlefield, governments such as the USA can legitimately affirm their use. In essence under the Hague Convention and the Geneva Convention these individuals are in fact quasi-military, i.e. ... ercenaries.7 British Human Rights lawyer Helen Kennedy has illustrated that there is vast problems with the USA naming freedom fighters, armed guerrillas who are not part of a state army as terrorists in order to punish them through vengeance ethically and a breach of humanitarian law. We [the UK] should not be tempted to take the American route There should never be a direct role for victims in punishment. If victims have a direct say in sentencing decisions, how will consistency be achieved between the victim bent on vengeance and the person willing to forgive8 The actions of the US authorities in Guantanamo Bay are an example of a nation of victims having a say in the punishment of possibly innocent people and these victims have no objectivity and mass cruelty and torture is happening. This is happening of civilians that have taken up arms to protect themselves and named terrorists. How does the US government legitimize civilian contractors who are getting paid for there services on one hand, but not freedom fighters on the other The distinction does not make legal or ethical sense, because morally a freedom fighter has a better argument for their actions and to become a war prisoner protected under the Geneva Convention than does the civilian contractor.9 Finally, the security issues that the uses of civilian contractors raise are vast. In the first instance is a contractor is being highly paid there are business reasons for their use on the battlefield.10 Therefore is it not conceivably possible that if the contractor is offered a higher price on the opposition, the needs of the business and money outweigh loyalty Secondly, there is the possibility that there will be infiltration by the opposition through the use of civilian contractors; especially in the case

Three Approaches To Management in Criminal Justice Essay

Three Approaches To Management in Criminal Justice - Essay Example In his Principles of Scientific Management, Frederick W. Taylor stated that all work organization responsibilities should be assigned to managers but not workers; scientific methods should be used in order to determine job performance, and the person best suited to perform each task should be selected to carry out such a task. Further, the principle states that workers should be trained to perform each task correctly; work performance should be monitored to make sure that specified procedures for a task are being followed correctly and the desired outcome achieved. Finally, work assignments should be planned, and work interruptions eliminated (Sapru, 2008). Lillian Gilbreth and Frank invented the motion study, which is an approach that reduces jobs to their basic movements. Henry Gantt developed a bonus and task wage plan where workers could be paid a bonus whenever they completed their job within the given time. The Hawthorne Studies used scientific techniques to study the behavior of human beings at work. More experiments saw researchers come into a conclusion that social factors explained the outcomes observed in all the Hawthorne studies. Douglas McGregor’s Theory X assumes that an average number of human beings dislike work and always avoid it whenever possible. As a result of this dislike of work, majority of persons must be controlled, coerced, directed, or even threatened with punishment prior to putting effort towards achievement of organization’s objectives. An average number of human beings like avoiding responsibility, prefer being directed, has little ambition, and above all, want security. Managers’ responsibility is to organize money, equipment, materials, and people. In addition, manager’s function is to direct workers’ efforts, motivate them, modify their behavior, and control their actions. Without such managers’ intervention, indiv iduals would be resistant to or passive about organizational needs. For the sake of the

Charles Dickens Essay Example for Free

Charles Dickens Essay It also suggests that his previous way of conducting himself has been broken and therefore he has changed. The form of the book and the way that it has been structured has a specific effect on the reader. It breaks the book down into chunks and emphasises the point of each one. The first and last staves, act as a prologue and epilogue to show the Scrooge before and after his moral transformation. This idea is backed up by the fact that the last stave is much shorter than the other four, acting as a round off to the book leaving you to imagine the rest of Scrooges life. In the third stave; The second of the Three Spirits Scrooge meets with the Spirit of Christmas Present who proceeds to show Scrooge how people are spending their Christmases. First he takes Scrooge through the town showing him the hubbub of Christmas shoppers getting food for the forthcoming day. There were ruddy, brown-faced, broad-girthed Spanish Onions, shining in the fatness of their growth like Spanish Friars; and winking from their shelves in wanton slyness at the girls as they went by, and glanced demurely at the hung-up mistletoe. There were pears and apples, clustered high in blooming pyramids; there were bunches of grapes, made, in the shopkeepers benevolence to dangle from conspicuous hooks, that peoples mouths might water gratis as they passed. Dickens uses such descriptive language here to focus on how much the food means to people who cannot afford much, and also how important the meal, and Christmas generally, is to everyone. The idea of food is again a running theme as in Dickenss time large quantities of food, as we commonly see now, were not possible during Victorian times. This was because they had no way of refrigerating food and therefore Christmas was very special in that people could feast at this one time of the year. The language he uses here is important because the way that he personifies the food shows how much attention was showed to it and we see this attention to detail at the beginning of this stave as well when the ghost is sat in a kind of throne of food. Also when the ghost is sprinkling blessings on passing peoples food the ghost tells Scrooge that the poor are more needy than the rich which Scrooge did not realise before as he was always looking out for himself only. Then they visit the Cratchits home where although they are very poor they all love each other and they have a very happy home, this contrasts with Scrooges home and work because although Scrooge is very rich, he is always unhappy. For example although they cannot afford a very big goose for Christmas lunch they are all very happy with it and none of them complain. Dickens especially conveys the feeling of a happy home with the use of a lot of dialogue between family members. Dickenss use of dialogue throughout the book is very effective and attracts the reader as it seems much more realistic. In the forth stave Scrooge meets with the Ghost of Christmas future who has come to show him what his future will be like if he does not change his ways. He is shown his colleges discussing his funeral, and is surprised to realise that none of them care for him. He is also shown a back street merchant to whom his belongings are being sold as no one looked after his house when he died. Finally he is shown that Tiny Tim has died because his family did not have enough money to support him. This stave is very important as it shows Scrooge the short-term consequences of his actions in life if he continues to live the way he is doing so now. And we see that he has fully changed by the end of the stave I will honour Christmas in my heart, and try to keep it all the year. I will live in the Past, Present and Future. The Spirits of all three shall strive within me. This clearly shows that he now cares fully and realises the error of his ways. This is an important part of the novel as it shows that he has changed fully, and the desperation he has at the end of stave four, makes the reader feel sorry for him. This has deliberately been done by Dickens as it shows that a character whom at the start of the story you despised, by the end of this stave you feel sorry for and hope that he does have a chance to show that he is a changed man. Finally in the fifth stave Scrooge gets a chance to show how changed he is as he has been with the spirits only the length of one night. He gets to go and visit his nephew and he raises the salary of his clerk. This particular part, when he raises the pay of his clerk, uses humour again as it shows just how surprised Bob Cratchit is that he is receiving a pay rise, as he cowers and holds up a poker. This use of humour raises the mood of the last stave. Also we see Scrooges mannerisms become much different and he laughs and becomes a different person. During the last stave the most important running theme is emphasised, that anyone can change for the better. This point is shown very clearly because Dickens creates the most horrible character he can and by the end of the book, as a reader you are inclined to like him. The book is appealing to readers because the moral points are important and it is a very heart-warming book that makes people feel better about themselves and want to embrace the spirit of Christmas, which is what Dickens intended.

Warehouse Performance Measurement Of Tesco Online Commerce Essay

Warehouse Performance Measurement Of Tesco Online Commerce Essay Tesco being the 4th largest online retailer as per revenue and 2nd largest online grocery retailer as per profit is constantly increasing its online grocery business which is being done from its Superstore chain. Tesco introduced a DOTCOM dedicated store more commonly known as DCOS (Dotcom only store) in Aylesford in 2009, which was a huge success and a boost to its online grocery business. As it was highly disturbing for the local superstores carrying out Dotcom business within them in line with the other regular store operations, it was becoming a quite a need to open a dedicated store Dotcom store in London, which TESCO did made possible by opening another DCOS in Greenford London. Tesco needed to reduce the impact of the Dotcom operation in certain stores at the same time addressing space constraints for the Van numbers in particular geographic areas, with a store-based order fulfillment model.  This led Tesco to re-evaluate the potential for a dedicated facility. Being a Tesco DCOS employee myself, I am very well known that the Product Availability is the highest priority in any DCOS or a superstore running Dotcom in it. Tweaking the performance of Warehouse is one of the key possibilities to make that high priority element easy to live with. According to Goh and Pinaikul (1998) for a company to run and have a sound and effective supply chain operations, companies have put a lot of their time and effort in this field. If the logistics of a company is well handled, it can take a company to a different level of success and it becomes easy for a company to defeat its rivals (Mentzer et al., 2004). With the new advancements in technologies there is always room for improvement and upgrades in a companys Warehouse Management. In DCOS Warehouse Management case there is a large number of logistic operations taking place. There have been many researches which discussed how to improve the performance of a companys warehouse by adapting different models and how to implement them. Moreover, this research will provide the company with the better understating of how to enhance its performance by measuring its performance with the variable benchmarking. Competitive advantage can be gained over rivals if the companys WMS is flexible and any process that is not performing well can be used as a benchmark to measure Warehouse Managements performance. Any flaws or drawbacks that maybe present in the current Warehouse Management Techniques will be reduced / diminished by the help of this research. LITERATURE REVIEW: WAREHOUSE MANAGAMENT: To have a very successful and efficient supply chain, an organisation has to focus on some major operations like warehouses. In todays day and age a firm is considered to be a flop which does not take care of its warehouse management functions. It has become vital for companies who manufactures on a large scale and in bulk to be efficient if their warehouse management system is not able to help company in all economic climates (Henneberry, 1987; Power et al., 2007). As per Brown (1990) and Lindley et al., (2008) there are numerous factors that are responsible for the vitality of warehouse management systems (WMS) some of which are that customers can place orders recently a new trend in the market has started in which people are leasing their land or building warehouses and then leasing them to different companies. This trend only came in to existence because of this mounting need of warehouses by mass producers and retailers (Jones and Hillier, 2000) Source: Adapted and modified from Mulaik and Cooper (2000). Warehouses can be defined in different ways but as per Gunasekaran et al., (1999) a warehouse can be defined as a place where commodities and goods are saved and stored for many reasons like social, commercial and assets safety. The designs of warehouses should be able to provide company with different technical and operations (Hassan, 2002; Faber et al., 2002). Warehouses are facilities that provide the right environmental conditions for the storage of finished goods and/or materials that require protection from the elements, as well as ensure commercial security and social safety (Gunasekaran et al., 1999). As such, warehouses have to be designed to satisfy a combination of several technical and operational requirements (Hassan, 2002; Faber et al., 2002). According to Lodree et al., (2004); Gaur and Ravindran, (2006) the basic functions that should be present in a warehouse are engineering structural capacity to bear the loads of the materials to be stored as well as the associated handling equipment, receiving and shipping operations and associated trucking, and the requirements of the operating personnel. Store-keeping places hold very important for proper warehouse management Gaur and Ravindran, (2006). There are following six major functions which are in the figure below. As per Lambert et al. (1998) there are more than 750,000 warehouses around the globe. These include private leasing warehouses, state of art warehouses, highly sophisticated warehouses, storage warehouses for companies and self-storage places. Lambert et al. (1998) further says that if the warehouses need so much money to have and operate then why they exist? He answers his own question and says that they play a vital role in companys supply chain management and they are usually build and kept to help companies in achieving transport and production economies, quality purchase discount and forward buys. Warehouses are a key factor in any organizations operations. Their main purpose is to supply, circulate, store, consolidate and changeover cargo. Henneberry (1987) and Power et al. (2007) claim that in todays day and age to consider profitable allocation or to consider large scale manufacture it is vital to give thought to the role of warehousing. According to Brown (1990); Lindley et al., (2008) partly because of the increasing dependence on the electronic alternatives for order placing by commercial and private customers and also to the manufactured goods industry the demand for warehousing is on an all-time high. Due to this demand of electronic order placing a greater weight is placed on distribution centres to hold the right amount of all the different stocks in order to meet clientele demands. Warehousing is required due to the developing capability in stockholding by vendors and producers. Boasting a direct impact in flexibility, operational costs and service levels warehouse operations prove that they are indeed indispensable (Baker and Halim, 2007). Warehouse operations being those of warehouse location, goods handling, warehouse design, inventory and storage guidelines hold a great importance in addressing the specific issues which are faced in achieving strategic goals. These issues can only be addressed once an organization has distinct strategies that will help define their long term performance (Bowersox et al 2002, p. 389; Bowersox and Closs 1996, p. 396). As stated by Korpela and Lehmusvaara (1999, p. 135) a major point to consider when allocating warehouses or distribution centres (DCs) is their location. This is a very important decision and requires a lot of thought as it will determine the continuing profitability of the organization, affect customer services and relations, costs and delivery schedules. As pointed out by Huertas et al. (2007) a great emphasis is placed on the layout of the facility as it is a major deciding factor in the success of an organization. The warehouses layout depends on its specific operational demands and distinctiveness i.e. modularity, flexibility, compliance, allocation of arrangements, convenience, and neatness. The design of the layout varies according to the nature of the organizations operations and has to be adapted as per those operational requirements meaning there is no set layout or methodology to follow. Because of the diversity of factors influencing a warehouses operations such as rack types and entrances, gangway entrance and harbour locations, selecting an adequate layout for any given case is not unimportant especially the usage of pallitization (Huertas et al. 2007). Those responsible for the development of these warehouse services need to focus around the understanding of the necessities of the businesses that will vacate these premises (Reichhart and Holweg, 2008). According to Varila et al., (2007) most warehousing development is an approximation of how the market in storehouse rental could evolve. Formerly to meet these types of demands made by most retailers and manufacturers was easier, as most of their needs had been met within their organization. Ultimately resulting in relative ease in the prediction of vacancy levels, also the ease in establishing the capability of warehousing; the support available to promote proficient use of the services (Rubrico et al., 2008). The main activities that play a vital role in the performance of a warehouse as defined by Koster and Warffemius (2005) are as follows: Internal product relocation, Return handling, Cycle counting, Quality inspection, and Cross-docking As a result of the above research one can come to the conclusion that in todays day and age warehouses plays a crucial yet multifaceted role in many supply chains. Baker and Halim (2007) emphasize that a warehouse makes up to 20% of the total logistics cost of an organization. And their critical role as great customer service providers in particular distribution centres as they are the final point of contact. INDUSTRY BACKGROUND: Tesco was founded by Jack Cohen in 1919 from a small grocery stall. And now it is the fourth largest retailer in the world measured by revenues and second largest retailer in the world measured by profits. Started from the 25p Stock Market share, it is now making a profit of more than  £200m. Tesco is now widely spread into more than 13 countries, including China and India. Tesco.com, commonly known as DOTCOM is the UKs most successful online retailer. Launched in 1996, and officially registered in 2000, it is one of the fastest growing business selling everything from vegetables to computers, electronic appliances to normal grocery via internet. Back to its beginning, it started making its 1st annual turnover of  £25m and was started from a single store. These days their average weekly turnover is around  £30m and they currently employee thousands of people in stores across the UK making the DOTCOM procedure possible. AIM, OBJECTIVE AND HYPOTHESIS: The existing warehouse management of Dotcom Only store TESCO Greenford is appraised. The primary aim is to recommend set of measures and strategies which can be used to measure the performance and eliminate wastes, respectively. By studying TESCO Greenfords warehouse management and conducting interviews with the senior managers, the weaknesses within their warehouse management will be identified and the solutions would be provided by relating it with the strategies available in the literature of this field and moulding it to the specific needs of TESCO DOTCOM Greenford. However, the core purpose of this research is to set the performance measures and eliminate wastes by identifying them in the complete Warehouse Management system implemented in all the TESCO Dotcom only stores. The research aims to benefit managers in understanding the weakness and the processes which are wastes. RESEARCH METHODOLOGY: In order to answer a question, a proper research has to be conducted (Zikmund, 2003). When a standard set of procedures and rules are followed to answer a research issue and to validate the findings attained by a systematic approach is called as research methodology (Ghauri and Granhaug, 2005). It has been widely observed that there is no fix method of conducting a research but a research should answer the question and should be relevant to the available data (Hussey and Hussey 1997). According to Schindler and Cooper (2001); Collins and Hussey (2003); Denscombre (2003) the result outcomes should be the main centre focus point for any research methodology. Substantiation of adopted research technique is briefly discussed in this section. Research design has been carefully selected to discuss the issues of the research for this particular research. The following plan is adopted: Research Philosophy: This will explain that which philosophy is used to develop the understanding of research. Research Design: This will provide with the design that is used to conduct the research. Research Approaches: this will discuss the major kinds of approaches and which one is adopted for this research. Research Data collection: this section will define the steps involved in the collection of the data For the purpose of this research we have used the research ONION which was introduced by Saunders et al. in 2000 and then it kept on modifying. According to Saunders et al., (2009) the last shape of Onion is given below: Research Philosophy: As we have discussed in order to go around this dissertation, the Onion process is used. So first of all the requirement of explaining the research philosophy is a must (Saunders et al., 2009). Research philosophy is basically an embarkation for the understanding of the knowledge upon which the research is based (Saunders et al., 2009). In summary we agree with Johnson and Clark (2006:108) that its not important how philosophical the research is and how well it is delivered but the way on how we reflect ourselves through those philosophies. There are many types of philosophies which are explained by Saunders et al. (2009) and are shown in the table below Table 5: Types of Philosophies Type Meaning Pragmatism Do you have to adopt one position? Ontology What assumptions do we make about the way in which world works? Objectivism How social entities exist independent of social actors? Subjectivism Understanding the meanings that individuals attach to social phenomena Epistemology What is acceptable knowledge in a particular field of study? Positivism Working in the tradition of the natural scientist Realism Do objects exist independently of our knowledge of their existence? Interpretivism Understanding differences between humans as social actors Axiology What roles do our values play in our research? Source: (Author) However for the purpose of this research we will only briefly discuss four main kinds of research philosophies. Positivism This kind of approaches provides researcher with a feeling of a scientist and it is conducted in the same way as any normal scientist will conduct a research (Saunders et al., 2009). Remenyi et al. (1998) has supported this idea that a research creates a hypothesis just like a scientist does when conducting a natural research. Realism Realism approach means that the philosophical things are different then the reality (Saunders et al., 2009). He explains it in detail by saying that realism is a branch of epistemology and it has two sub divisions in business and management research which are direct realism and critical realism. According to Saunders et al (2009) by focusing on the knowhow of generating a common understanding of humans and basing it on the experience of external factors that have at one point impacted a business research can be conducted. However these factors that have impacted an organization may not provide suitable evidence to the exact situation. Interpretivism This kind of research is explained by Saunders et al. (2009) as a research in which the researcher has to bear in mind that all the humans are social actors and they all have a viewpoint towards things. He further explains that in this kind of research, a research has to get involved into details of the social world of the research question and has to observe the point through their i.e. social actors point of view. Pragmatism Saunders et al. (2009) argues that pragmatism is that the most important factor is that what type of question you adopt for research and one may be more important than the other in order to achieve the answer. He further uses the support of Tashakkori and Teddlie (1998) who suggests that it is more appropriate for the researcher in a particular study to think of the philosophy adopted as a continuum rather than opposite positions (Saunders et al., 2009, pp 109). Saunders et al. (2009) says that the research philosophies can be explained in more detail by the use of a concept known as research paradigms. Furthermore, this terminology, paradigm, is usually used in social science researchers and can become a cause of confusion as it gives birth to many meanings of one things. Research Design There are many ways to conduct a business research and there is as such no limitation which says that one research is superior over another (Hair et al, 2003). One may think that the data is qualitative or quantitative or may be both but again its all on how you want it to be (Jankowicz, 2003; Stevenson and Cooper, 1997). EXPLORATORY RESEARCH This can be used by people who are not highly knowledgeable and is completely based on the exploration. On the other hand, this research can be used for companies and industries which are highly innovative and are always evolving into new things. The importance of this type of research can be determined by the words of Swaddling and Zobel (1996) in the following pattern: When conducted well, exploratory research provides a window into consumer perceptions, behaviours, and needs. It enables companies to produce new products and make them successful easily. Highly level decision and a better understanding of market can be gained by such research. This type of research leads company into the innovation of new products and these products being a result of exploration is always very beneficial and profitable for companies. Research Approaches There are many kinds of researches approaches and any of them can be used to attain the answer of ones research (Saunders et al., 2003; 2009). The selected approach basically reflects the way theory was built when the project was initiated and is most critical selection (Creswell, 2003; Saunders et al., 2009). In general there are 5 major approaches and any of them can be adopted. According to Zikmund (2003) there are two major approaches i.e. Theoretical and Methodological and both of these are divided into sub category of Inductive/Deductive and qualitative/quantitative, respectively. While on the other hand Collis and Hussey (2003); Gray (2004); Hussey and Hussey (1997); Mangan et al. (2004) all agree that there are two major kinds of approaches which are Deductive and Inductive. Now in recent years another researchers introduced a new kind of research which is known as Abductive (Kovacs and Spens 2005; Saunders et al., 2009). We will discuss each approach briefly and will select the one that is most suitable for the purpose of this research. DATA COLLECTION: One of the most important parts of any research is the data collection method. There are several methods of collecting data but the method is completely dependent upon how the research is conducted (Creswell, 2003). Due to the nature of this research deductive technique is used and to collect data for such technique is defined by different researchers in a different way. Amongst all the methods researchers agree upon few like Sampling, Secondary data, Observation, interviews and Questionnaire (Saunders et al., 2003; Yin, 2003; Collis and Hussey, 2003; Saunders et al, 2009). Each step is discussed briefly as following: Secondary Data collection: The data which is collected by someone else and not by user is generally referred to as a secondary data (Saunders et al., 2009). The secondary data can be qualitative or quantitative (Collis and Hussey, 2003). Secondary data is beneficial if the cost issues exist or the time is not trying to be wasted and this kid of data can also be descriptive or exploratory (Saunders et al., 2009). Data collection technique: Initial information would be collected by the communication with the strategic level manager of TECO Dotcom Greenford and the website of the Dotcom Stores Tesco and the main website of the Tesco Plc. These websites would be used to collect the general background of the company. Later on Warehouse Manager of Tesco Dotcom Greenford will be provided with the some information which includes the current situations of the Warehouse Management of the store and the interaction between its clients. The literature review will be providing the support on the research on overall basis as well. Primary Data Collection: secondary data is usually not always enough to understand and answer the research (Saunders et al., 2009). This kind of data can only be collected by having a deeper understanding of the issues and is usually targeted to answer the specific issues (Ghauri, 2005 and Saunders et al., 2009). Furthermore, it is explained that there are three major ways to collect primary data i.e. in depth interviews, questionnaires and observations which usually reflects the situation in detail and gives a researcher with a clearer picture of the situation (Creswell, 2003; Saunders et al., 2009). Data collection technique: Primary data would be collected by paying visits to the Tesco Dotcom Greenford, conducting in depth face-to-face interviews with the managers at Tesco Dotcom Greenford and then a detailed telephonic interview with the Warehouse Manager at Aylesford Dotcom Only Store, as they are directly involved in the issues faced by Tesco Dotcom Greenford at the moment (a good reason why Aylesford is involved with the problems faced by Greenford store is because it is the only relevant store of the type in UK and is up and running successfully). The interviews would be provided with the great deal of understanding of the situation. Later on, observation would be made about the processes happening at Tesco Dotcom Greenford and the email conversations between Tesco Dotcom Greenford and its suppliers. The issue with the palletisation and inventory is the major issue between Tesco Dotcom Greenford and Suppliers. Once the data would be collected then the communication through email will continue in order to fulfil any other requirement to conduct this research.

Technology and Music †Baroque, Boole, Binary, Beams, and Bach :: Technological Musical Music Essays

Technology and Music – Baroque, Boole, Binary, Beams, and Bach Is this merely a clever alliteration or a deep connection between science, mathematics, and western culture entirely overlooked? The following seeks to join these five B's in an intimate manner, bringing to light this seemingly complex connection. Part I: Baroque and Bach Chromaticism and elaborate forms of ornamentation characterize the Baroque period of music. In fact, this period, lasting from the late sixteenth century through the early eighteenth century, marked the first period in which composers truly used harmony in music. In addition, this period brought to fame many composers whose music is still enjoyed today including Pachelbel, Handel, Haydn, Vivaldi, and Bach. Born in 1685, Johann Sebastian Bach (hereafter Bach) made himself one of the most renowned western composers of all time. Johann Ambrosia Bach, Bach's father, and Johann Christoph Bach, Bach's brother, trained Bach in music at a very young age. In 1703 at the age of 18, Bach began a series of jobs as organist in Arstadt. Twenty years later, Bach became cantor and choral director at St. Thomas Church in Leipzig. He held this distinguished position until his death. Before his death in 1750, though, Bach had had two wives (the first died in 1720) and 20 children some of whom became musicians as well. He had written such notable pieces as the Brandenburg concertos, "The Art of the Fugue," various religious compositions including the "Mass in B minor" and the "St. John Passion," numerous fugues, preludes and overtures, and more than 300 cantatas. Bach's "Overture Number 3: Air" is a composition often played at weddings, graduations and the like. Though it is only about four and one half minutes in length, it is one of my personal favorites, and will be noted later as this odd connection continues. Part II: Boole and Binary George Boole, a self-taught mathematician and logician, was born in England in 1815 (approximately 65 years after Bach's death). In 1854, he published "An Investigation of the Laws of Thought, on Which Are Founded the Mathematical Theories of Logic and Probabilities." Therein can be found the basis for substituting symbols for the words in the language of logic, thus Boolean algebra is born. Today, computer scientists often use Boolean to relate sets of data. Using the words AND, OR, NOT, IF, and EXCEPT, a Boolean algebraist can determine the truth of a statement as well as rewrite the statement in a more understandable form.

Part II: Boole and Binary George Boole, a self-taught mathematician and logician, was born in England in 1815 (approximately 65 years after Bach's death). In 1854, he published "An Investigation of the Laws of Thought, on Which Are Founded the Mathematical Theories of Logic and Probabilities." Therein can be found the basis for substituting symbols for the words in the language of logic, thus Boolean algebra is born. Today, computer scientists often use Boolean to relate sets of data. Using the words AND, OR, NOT, IF, and EXCEPT, a Boolean algebraist can determine the truth of a statement as well as rewrite the statement in a more understandable form.

Government must seekto meet citizens needs :: essays research papers

SOME INVESTORS have applied to the government for permission to operate ferry services between Tuen Mun and Macau and the Pearl River Delta (PRD). However, the Transport Bureau has delayed approving their applications, greatly to the applicants' and residents' resentment. If there were such services, things would be much more convenient for north-western New Territories residents who want to go to Macau or the PRD, and it would be in line with Chief Executive Tung Chee-hwa's strategic plan of making better use of the PRD hinterland. People cannot help asking why it remains impossible to offer the public such ferry services. The government has been saying it wants to remove obstacles to the market's smooth operation. However, it has delayed approving those applications, whose approval would bring about new jobs. How does the government propose to justify itself? Nearly one million people live in Tuen Mun, Yuen Long and adjacent areas (north-western New Territories). At present, a citizen living there must take a one-hour vehicle ride to Tsim Sha Tsui or Central if he wants to go to Macau or the PRD by ferry. Such a ride takes almost as much time as a ferry journey from Central to Macau. More important, Tuen Mun is nearer Macau and the Pearl River's mouth. It would take 10 minutes to 15 minutes less time for a jetfoil to travel from Tuen Mun to Macau than from Central. If there were a Macau ferry terminal there, north-western New Territories citizens going to Macau could save more than one hour and some money. Two companies have applied to the government for permission to operate ferry services from Tuen Mun to Macau and Nansha. Last year 19 million citizens left Hong Kong by sea. Most of them went to Macau or the PRD. As one out of seven Hong Kong citizens live in north-western New Territories, one may infer that last year more than two million north-western New territories residents travelled to Macau or the PRD by ferry. If the government decided to have a new Macau ferry terminal in Tuen Mun, things would be much more convenient for them, and investors could do business. However, nothing has been heard about those companies' applications since they were submitted. In response to our inquiries, a Transport Bureau spokesperson said that, since the two existing Macau ferry terminals would not become saturated until 2011, there was no urgent need of building another.

Application of Honeycomb Sandwich Structures

Sandwich construction by and large consists of 3 parts ; the nucleus stuff that is lightweight and is covered by face sheets from the top and the underside. The stuff of the face sheets are normally made from stuffs that have high stiffness, while the nucleus of the construction is made up of extremely compressive stuff and high shear strength.Even though the constructions are lightweight, they have a high fracture/bending strength and buckling strength. Therefore this allowed the sandwich structures to go an indispensable portion of the modern lightweight building. The composite sandwich constructions are by and large preferable structural signifier because they can be easy constructed by utilizing stuffs that are significantly lower in costs, while they besides have higher bending stiffness, while keeping the same sum of fibre reinforced polymer stuffs being used. The nucleus is the portion that is responsible for the separating and repairing the shins, while besides defying cross shear, screening and radiation, absorb impact energy, and insulate heat transportation. The bonding of the faces to the nucleus, is to obtain a burden transportation between all the constituents. Polymeric cores that have higher denseness besides have higher shear and compaction strengths, but this besides makes them heavier hence a via media has to be reached between keeping low weight and high public presentation. The faces of the sandwich construction should hold high stiffness that will therefore five high flexural rigidness, a high compressive strength and high tensile strength, should be impact immune, good surface coating, and eventually it should besides be wear and environmental opposition so it does non respond with the surrounding. The usage of â€Å"sandwiching† , we are able to dramatically increase the strength and flexural rigidness, if we are to compare it to a individual tegument construction while non adding much weight. General demands of the construction:In order for the home bases to defy the compressive, tensile and shear emphasiss that are induced by the design burden, they should be thick plenty.The nucleus should hold more than adequate strength in order for it to defy the shear emphasiss that are being induced by the tonss, while besides the adhesive must besides hold sufficient strength, so it can be able to transport the shear emphasis into the nucleus.The nucleus should besides be thick plenty and have enough shear modulus to be able to forestall the overall buckling of the sandwich under tonss, and to besides forestall crimping ( the procedure where two pieces of metal or ductile stuff are joined by the distortion of one or both of them to keep one another )The nucleus cells should be little plenty in order to forestall dimpling ( pregnant chads are the little indentures or depressions that appear on the surface of a organic structure ) under burden.The nucleus must hold adequate compress ive strength that will assist it defy the suppression by the designed tonss that act normal to the panel facings, or by the compressive emphasiss that are induced through flection. The overall construction must hold sufficient shear and flexural rigidness to be able to avoid the inordinate warps under the designed burden.Dame that occurs in sandwich complexs, is a instead complex phenomena that is due to the legion failure mechanism.The honeycomb constructions are either natural constructions formed such as from bees, or semisynthetic constructions that use the geometry of the honeycomb in order to let the minimisation of the measure of stuffs that is being used in order to assist make a minimal weight while besides holding minimal stuff costs. The honeycomb structure’s geometry can differ immensely, but the most common characteristic of all of the constructions is the scope of hollow cells that are formed between the thin perpendicular walls. Normally the cell forms are eith er hexangular or columnar. The honeycomb like construction offers a stuff that has really small denseness and comparatively high compaction and shear belongingss. The stuffs of the semisynthetic honeycomb structural stuffs are often made by puting the honeycomb stuff between the two thin beds that provide the strength when there is tenseness. A plate-like assembly signifiers. The honeycomb stuffs are immensely used where a marginally curved or level surfaces are required and their high weight to strength ratio is valued. They are to a great extent used in the aerospace industry chiefly for this ground, while some stuffs such as advanced composite stuffs and fibreglass have been included in projectiles and aircrafts for over 50 old ages now. Honeycomb sandwich constructions can be found in several other applications, such as from something every bit basic as packaging stuffs utilizing paper-based honeycomb ( composition board ) , to athleticss merchandises such as snowboards and skis. Honeycomb sandwich constructions are industry by utilizing a broad assortment of different stuffs that depend on the application intended and the features that are required. Honeycomb nucleuss such as paper/cardboard and thermoplastics, used for low stiffness and low strength for low application tonss, to high stiffness and high strength for applications that require high public presentations, the nucleuss used in such instances are from fibre reinforced plastics or aluminium. Harmonizing to the size of the panel, the denseness or sum of the honeycomb cells that are within it, and the facing stuff the strength of sandwich panels are used. The honeycomb complexs are immensely used in assorted industries, from the automotive and aerospace industries, to furniture and wadding industries. The construction is named â€Å"honeycomb† due to the ocular resemblance to a bee’s honeycomb Honeycomb nucleuss are used in a broad assortment of applications such as ; Marine vass, aerospace applications, walls, doors, ceilings, warming and air conditioning units, in mensurating the energy loss of sound extension in media, lifts, in the directional systems of air, visible radiation and H2O, and eventually in bathroom and kitchen dividers. They are besides used in applications such as in the devising of human body of the modern type of expression one autos. In the expression one autos the honeycomb is sandwich in between two C shins that will make a really stiff and strong construction, which will therefore supply the protection to the driver if he is to hold a unsafe clang. Advantages of honeycomb sandwich over other conventional stuffs:It has really low weight therefore makes it easier to work withLastingnessHigh stiffnessSaves cost in productionIt requires really small careAdvantages of honeycomb sandwich constructions:Without dramatically increasing the weight, elevated degrees of strength and stiffness can be reachedThe sandwich building besides could move as either a thermic dielectric or a thermic transportations, this procedure depends on the stuff that is traveling to be used.Besides the moistening of noise and quiver occurs due to the nucleus stuff.Relatively light stuffs could be used.A huge array of stuffs such as C, paper, aluminium etc. could be used.The nucleus has a high strength to burden ratio while besides holding an first-class compaction strength.A disadvantage of the honeycomb nucleus is that some of the stuffs are expensive, while other stuffs are caustic depending on the stuff that is being used. Different types of nucleus stuffs that are used are:Nomex honeycombVinyl sheet frothBalsa woodPolyurethane sheet frothAluminumPaper/cardboard nucleusNomex honeycomb: is flame and fire resistant, has good impact opposition, is flexible, and lightweight. The Nomex honeycomb is chiefly used in the aerospace industry for the structural applications, due to it offering the best strength to burden ratio of nucleus stuffs. This peculiar type of honeycomb is an aerospace class fibre that is coated by phenol. Due to the cell structures being over expanded, it allows it to obtain more flexibleness, which hence besides makes it the most suitably applied in tight radius curves. Vinyl sheet froth: is one of the most adaptably used nucleus stuffs in the market. It is a closed cell, stiff stuff that is immune to thin acids, hydrocarbons, base, sea H2O, Diesel oil, methyl intoxicant, gasolene, and it besides able to self-extinguish its ego. It is presently being used on a large graduated table in the aircraft industry and the public presentation automotive constructions industry every bit good. It can be applied anyplace, such as topographic points that require high belongingss and easy handling. The froth is typically thermoformed in an oven or utilizing a heat gun while force per unit area is gently applied. If ultimate if it is desired to make the ultimate Peel strength a perforation roller is used in order to increase the surface country of the froth, which leads up to the addition of the Peel strength an excess 15 to 20 % . The vinyl sheet froth is really good appreciated due to it holding superior structural and mechanical belongingss. They are besides re ally easy handled in treating such as thermoforming, cutting, and determining. They are besides used in the procedure of rapid majority edifice, or in the bonding of single sheets that will supply the extra thickness that is needed in mark countries. It is besides H2O immune and insulative. Polyurethane sheet froth: It is stiff, with first-class floatation and thermic insularity belongingss, while it is besides closed cell. Some of the grounds as to why the Marine industry has been utilizing the froth extensively for the last few decennaries are that: -it is non really expensive when a lower belongings cored laminate is required. -The sheets are besides available in a broad assortment of thicknesses and are besides stiff. -The closed cell construction, allows it to defy the soaking up of H2O, gasolene, and oil.The froth demands to be stored off from sunlight in order to avoid debasement. It can besides defy temperatures that range from 60 F up to 300F. Balsa wood nucleus: This is the most used type of wood nucleus. It was specifically used in in the Marine industry, normally used for boat hulls and decks. One of the chief grounds as to why balsa is used, is because it is a natural merchandise, and could provide the market demand invariably due the balsa tree’s speedy growing rate. Some other advantages include its low cost, it is a light stuff yet being really strong. Some disadvantages include, – the possibility of being damaged by H2O, because it rots when it gets wet. – when we compare it to a solid fibre glass stuff it is more expensive, hence the fibre glass is by and large used as the alternate stuff to the balsa wood nucleus in the Marine industry. Aluminum honeycomb nucleus: The aluminium honeycomb construction provides the maximal stiffness that could be obtained and is the stuff that has one of the greatest strength to burden ratios, when compared to the other available structural nucleus stuffs. A chemical transition surfacing to protect the foil from corrosion is used after the foil is good cleaned. If maximal protection from corrosion is wanted, Alcore’s proprietary PAA coating is used in order to protect it from really rough environments. Some of the aluminium honeycomb belongingss include: -its first-class strength to burden ratio. –its ability to defy corrosion. –its ability to execute in elevated temperatures. –resistant to fungus and fire. –easily formed and machined. –does non absorb wet. –high thermic conduction. –withstands up to 350F. –has high stiffness. –super level surface. –it is a sound and thermic dielectric. –absorbs quiver. –it can be recycled . –easily fabricated and installed. –convenient in care. The applications where aluminium honeycomb nucleus could be used in include: Marine vass, doors, walls, ceilings, warming and air conditioning units, in mensurating the energy loss of sound extension in media, air and visible radiation and H2O directional systems, lifts, and eventually in bathrooms and kitchen dividers. Paper/cardboard honeycomb nucleus: Is normally used in the fabrication of panels in the trappings industry and is by and large used in the interior doors in the edifice sector.Some of the applications where the paper nucleus is used include: advertisement shows, it is used in the devising of carton palettes, used in the devising of container palette, automotive parts, trade carnival bases and packaging stuffs. It is a comparatively light and strong stuff, and its concentration and strength are due to the about perfect hexangular form that its cells make, which hence makes it highly immune to compaction, and is applicable in a broad assortment of instances. Properties of the paper honeycomb nucleus include: it is a 100 % reclaimable stuff, has high force per unit area strength, environment friendly, due to its great strength to burden ratio it is an first-class nucleus stuff that is able to be used for most applications, it is easy to utilize, really cost effectual, it is adaptable to huge utilizations in the uninterru pted production procedure, it gives a smooth surface with the stuffs that are confronting it, it is used in either cold or hot pressure, can be easy stored, has smaller weight, due to it being a 100 % reclaimable it produces no waste, and eventually it is a good noise and heat dielectric. Thevaluesof thermic insularity are relatively good and they depend on the denseness of the nucleus and specific building. In some instances, the thermal demands determine the thickness of the panel that is needed. By make fulling the cells with other stuffs such as loose insularity or froths so we can farther better the insularity values of the honeycomb. The distortion of the panels due to the different thermal and wet conditions was discovered to be about equal to the same order of as that of the panels that are made of plyboard which is glued to the wood frames while being insulated and have emphasiss moving on its faces. When the fire opposition of the honeycomb panels are compared to the about hollow panels with similar facings, it is significantly higher. While to farther increase the fire opposition, the cells are filled with foamed rosin. To the shapers of the merchandises such as furniture and doors the advantages of the sandwich building to them is clearly seeable and favourable. When builders and designers are interested in new edifice stuffs, the chief factors that are inquired are the strength of the stuff, opposition to fire, and the sum of thermic insularity that the honeycomb nucleus affords, how practical it is to utilize the sandwich buildings in edifices, and eventually the convenient beginnings of the sandwich panels. To bring forth the wavy or corrugated type of the honeycomb, the channel or cell is made by organizing the paper in between the grooved axial rotations on the equipment that is used in the procedure of bring forthing the corrugated container board. The advantages and disadvantages that are unnatural to the building differs from each type of nucleus. This difference lies in many factors such as, the equipment that is needed for the production procedure, the restrictions in adhesives and rosins, strength of stuff, the changing trouble of accurate film editing, easiness of transportation, the thermic insularity belongingss, and many other factors. When the rosin and basal stuff intervention are mentioned, such jobs as the rosin, fibre, lastingness, and wet strength are significantly common to all types of nucleuss. By utilizing paper that is lighter in weight, we are able to cut down the cost of the initial stuff every bit good as cut downing the saturating rosin needed to make the construction based on a given volume. The thermic insularity values of a honeycomb nucleus depended on the type of building and its denseness. Filling the cells with foamed-in-place rosin or with fill stuffs resulted in some betterment in the thermic insularity value. The lowest value obtained compared favourably with that of common mineral-wool merchandises. Paper honeycomb assemblies in one signifier or another are going more and more of import as nucleus stuffs in sandwich-type edifice panels. Light, strong, and stiff panels can be produced by adhering facings plyboard, chipboard, aluminium, or other sheet stuff to such lightweight nucleus stuffs. Research work on sandwich building has been carried on at the Forest Products Laboratory for over 20 old ages. The early work was devoted to the development of high-strength, lightweight sandwich stuffs suited for aircraft application, and the finding of their technology belongingss. After World War II, because of the increasing demand for edifice stuffs, the rules learned in probes of aircraft stuffs were modified to bring forth panels suited for edifice intents. For such applications, thermic insularity and lastingness became more of import and strength demands possibly lessened. It was evident early in the work on paper honeycomb nucleuss that, if they were to be used in panels where any great grade of thermic insularity was needed, it would be desirable to make full the cells of the honeycomb. In 1944, a few exploratory efforts were made to make full the cells of the honeycomb, and a phenolic rosin was successfully foamed into the honeycomb constructions. Cores were forced into blocks of balsa wood with small trouble. These few experiments indicated the possibility of make fulling the air infinites of the honeycomb construction when improved ‘ insularity belongingss are needed. To utilize sandwich building in edifices erected in cold northern climes, it appears to be necessary to make full the cells to obtain insularity belongingss equivalent to those of conventional insulated building. In some instances, increasing the thickness of the nucleus stuff between the facings may be the most economical manner of bettering insularity belongingss ; in other instances it may non be practical. When sandwich building was foremost considered for constructing stuff in dividers and doors, its ability to absorb or convey sound was frequently questioned. Most of these panels would hold really small built-in sound absorbing belongingss because of the hard-surfaced facings and the low mass of the panels. These belongingss might be improved, nevertheless, by agencies of perforations in one of the open faces or by particular nucleus buildings. Paper can be converted to honeycomb nucleus in a figure of different ways. The expanded type is made by interspacing sheets of treated paper with parallel and uniformly spaced strips of adhesive and spread outing the assembly, after adhering, to organize a nucleus with hexangular cell subdivisions ( fig. 1, top ) . Another type is made by looping and adhering sheets of resin-treated paper to organize round cells stand foring a â€Å" figure 8 † in cross subdivision ( fig. 1, underside ) . From assemblies of sheets of corrugated paper, a figure of different nucleus buildings are besides possible, some easier than others to manufacture. Eight of such buildings are shown in figure 2. Most of the experiments reported herein were made with the corrugated nucleus.
