Kant Moral Law Theory Essay

â€Å"Two things fill the mind with ever new and increasing admiration and awe the oftener and more steadily we reflect on them: the starry heavens above me and the moral law within me.† – Kant (1788), pp, 193, 259 Immanuel Kant introduced and initiated his ‘moral law theory’ in the late 18th century. The doctrine in question sought to establish and constitute a supreme or absolute principle of morality. Kant disputes the existence of an ‘ethical system’, whereby moral obligations are obligations of ‘purpose’ or ‘reason’. The accuracy of actions [i.e. the rightness or wrongness of an individual deed] is determined by its configuration and conformity with regard to ‘moral law’. Evidently, according to Kant, an immoral transaction is invariably contemplated as an illogical or unreasonable occurrence or action. The supreme moral principle is a consistent â€Å"working criterion† that proves to be â€Å"practically helpful and theoretically enlightening† when used by rational agents as a guide for making personal choices (Kant VI). A supreme guiding moral principle must carry with it an absolute necessity and be done out of duty to the moral law in order to be free from corruption. Kant believed in a fair and impartial law. He accredited and affirmed the presence of an objective moral law that we, as humans, were/are able to identify with through the process of reasoning. Kant argued that we are able to recognise and distinguish moral law, without making reference to the possible consequence or outcome. Immanuel Kant declared a differentiation between statements [i.e. posteriori and priori] that he believed to coincide with moral law. A posteriori statement is one that is based on experience of the material world. In opposition, a priori statement requires no such knowledge; it is known independent of the phenomenal world. Furthermore, Kant continued to make additional distinctions with regard to analytic and synthetic statements. An analytic statement, he claims, is one that by its very nature is necessarily true, as the predicate is included within the definition of the subject. Example: – [â€Å"all squares have four sides†]. The previous statement is of an analytic nature, as the predicate, i.e. the square having four sides, is implicit and is part of the definition of the subject – [â€Å"square†]. An analytic statement is necessarily true – true by its own authority, and is purely explicative, as it tells us nothing new about the subject. In contrast, a synthetic statement is one in which the predicate is not included in the definition of the subject, and thus is not necessarily true. A synthetic statement also tells us something new about the subject. Prior to Kant, it was widely accepted that there were only two types of statement: a priori analytic and a posteriori synthetic. Kant accepted these two statements although believed there to be a third: a priori synthetic statement. These are statements that are known independent of experience that may or may not be true. Kant claimed that these priori synthetic principles are inherent within us and therefore subsequently form the basis of all moral decision making. Kant’s theory is based on and is primarily concerned with the aspect of ‘duty’. Kant believed and promoted the notion that to act morally is one’s ‘duty’, and one’s ‘duty’ is to act and proceed in accordance to the principles of moral law. Due to this, Kant’s theory is categorised and distinguished as a ‘deontological argument’. A deontological theory is one that maintains the moral rightness or wrongness of an action and depends on its fundamental qualities, and is independent of the nature of its consequence – â€Å"Duty for duty’s sake†. This perspective can be viewed in contrast to the beliefs and ‘rules’ associated and belonging to teleological arguments, i.e. utilitarianism. Immanuel Kant argued that moral requirements are based on a standard of rationality he dubbed the â€Å"Categorical Imperative. The categorical imperative has derived from the initial belief and notion that humans base their moral judgment on pure reason alone. This view can be viewed in contrast to a ‘morality theory’, which assumed/s that human’s actions are guided by emotions or desires. Example: When deciding what I ought to say to a friend who is distraught. Rationale would dictate that I give sensible advice, whereas my emotions may impulsively tell me to give comfort and sympathy. The categorical imperative declares and differentiates between obligatory and forbidden actions, and places further emphasis on the notion of ‘duty’. This statement can be strengthened through the following quotation – [â€Å"All in imperatives command either hypothetically or categorically†¦ If the action would be good simply as a means to something else, then the imperative is hypothetical; but if the action is represented as a good in itself†¦ then the imperative is categorical.†]. Example: If someone tells me that they will buy me dinner if I give them a lift into town, then this is a conditional action and would fall into the hypothetical imperative category. Conversely, if I think that I should give my friend a lift into town with no other agenda (i.e. she will not buy me dinner because of it), then this is a categorical imperative because it is independent of my interest and could apply to other people as well as myself. There are three principles of the categorical imperative: * Universal law; * Treat humans as ends in themselves; * Act as if you live in a kingdom of ends. 1. The categorical imperative is [â€Å"Do not act on any principle that cannot be universalised†]. In other words, moral laws must be applied in all situations and all rational beings universally, without exception. 2. [â€Å"Act that you treat humanity, both in your own person and in the person of every other human being, never merely as a means, but always at the time as an end.†] – The previous statement declares that we must never treat people as means to an end. You can never use human beings for another purpose, to exploit or enslave them. Humans are rational and the highest point of creation, and so demand unique treatment. 3. The quotation [â€Å"So act as if you were through your maxim a law-making member of a Kingdom of ends†] states Kant’s belief in the fact that humans should behave as though every other individual was an ‘end’. In conclusion, it is arguable that the categorical imperative possesses a sense of authority with regard to what actions are permitted and forbidden under Kant’s moral law theory.

Making People to Vote

I believe there are many ways to get people to vote, but I believe the main way is through education. When people are educated on a subject, they know about it and what to do with it. A lot of people are uneducated on voting, so they don't know things, like how to register and where to vote. If we educate the public on voting and the benefits of it, more people would vote. This essay will discuss some of the possible ways of educating the public on voting. One way would be to make an educational commercial aimed towards the younger people in our society. Kind of like what Rock The Vote did, but more informational. My commercial would inform people how to register, how to find out where the voting booth is, along with all the set backs of not voting. I would talk about how you're giving up your freedom by not voting, because you're letting someone else decide who should be in charge. I would also make it very clear that everyone's vote matters! That's another big problem, each individual feels that they can't make a difference, because â€Å"they're only one vote†. I would also talk about the importance of knowing the people running in the elections and what they stand for, because if you're uneducated, you really won't make a difference. This is basically what I would talk about and it would definitely be aimed towards younger people. Another way to get people to vote would be to have a required educational program in high schools, that teaches kids every thing they need to know in order to vote. This would work very well, because it would teach younger people how and why to vote. You could also discuss candidates, how to find out about them, and what they stand for. Another way would be to educate people through fliers and brochures. This would be a lot harder and wouldn't reach as many people, but it would still educate some. A better way would be through a national magazine that talked about the importance of voting and the candidates that are currently running. This would work very well, because you would be educating people and getting them excited to vote. Overall, there are many ways to get people to vote, but I personally believe that voting comes through education. I believe the best way to increase the voting, is to increase the education of it among younger people.

Do you accept extra hours at your work Should your work ethic be based Assignment

Do you accept extra hours at your work Should your work ethic be based upon the state of the economy - Assignment Example For example,  my job requires me to have open availability on the weekends, however  I don't always work  every Saturday and Sunday   of the month. I believe the acceptable amount of extra hours that an organization should expect from their workers are 26 per month; apart from the Monday to Friday's 40 hour/week. Also, even thought one might work 9 hours a day, we waste around 1 hour and 30 minutes per shift; so in reality we do not work exactly 40 hours per week. YOUR RESPONSE HERE: I agree that in any organization, an employee must be informed of the actual expectations and responsibilities demanded from the job. Like in retail stores, whatever extra hours that need to be rendered should be paid for as overtime pay. These are just to ensure that employees’ rights are protected and employers comply with the regulations imposed by the Labor Department. Person #2 While I may not completely agree with the demand, I don't think that it is completely unfair. I believe that this subject is more of a gray area because of what each individual and each company would consider as being reasonable. If you are expected to work extra hours on  a regular basis* (i.e. 2 or more extra hours per day) at the same salary, I feel that this is definitely unfair. Looking at it from a personal standpoint, I know that I would feel  used and underappreciated.

History of Hip-Hop Essay Example | Topics and Well Written Essays - 1000 words

History of Hip-Hop - Essay Example This essay begins from explanation that the music that is known to us today as hip-hop was then called disco rap. It was a man named Keith Cowboy, a rapper with the band Grandmaster Flash and the Furious Five that coined the famous term â€Å"Hip-hop†. The term â€Å"hip-hop† that is analyzed in the first part of the essay was used for the first time in print by Steven Hagar, an author in his work the Village Voice in the year 1984. But this does not imply that the Keith Cowboy was the true pioneer of hip-hop music and culture, but on the contrary, hip-hop was there even before Cowboy was born, only then it was known by a different name. This essay tries to trace the history of hip-hop. And for that one will need to go about four decades back to the 1970’s, to the city of Bronx. The essay describes the history of the music genre to 21th century and to the times when the rappers started incorporating serious issues into their lyrics. The Jamaican born Clive Campbe ll who later famously came to be known as Kool Herc or DJ Kool Herc can be said to be the ‘godfather‘ of hip-hop music. Essay focuses not only on his impact to the genre, but also provides the reader with detailed analysis on the 80s and 90s history of hip-hop. The 80’s saw a dramatic change in the hip-hop scenario. The hip-hop of the 70’s got more complex as it developed more. A glance of Hip-Hop through the 80’s, the 90’s and the new Millennia is also described by the researcher. In concluion, the researcher suggests to enjoy the present scenario of hip-hop music and what will follow next.... MC would just go on about pairing nonsensical rhyming words, making a clown of their friends and enemies with their witty words, hence taking the shape of folk music. It was later, that the rappers started incorporating serious issues into their lyrics. (History, n.d.) DJ Kool Herc the Pioneer of Hip-Hop The Jamaican born Clive Campbell who later famously came to be known as Kool Herc or DJ Kool Herc can be said to be the 'godfather 'of hip-hop music. He was born in Jamaica on April 16th 1955 and was a Jamaican DJ by profession. The credit for making hip-hop music what it is today goes to DJ Kool Herc. He was the one to experiment with the segregation of the instrumental part of a record and give more emphasis to the drumbeat or the "break". He used two turn tables, a set up used by the DJs and the same record in each of the turn tables hence elongating the break of the beat. This method of breaking the beat of the hard funk and rock records and mixing them with Latin percussion then formed and still forms the basis of hip-hop music. Later Kool Herc used dancers to dance in tune to his prolongated breaks and guess what, there were break-dancer. Kool Herc influenced many other greats of hip-hop including the Afrika Bambaataa and Joseph Saddler a.k.a. Grandmaster Flash who later starte d DJ-ing in Kool's fashion. It was due to Kool's impact that Bambaataa a notorious general one timer of the Black Spades gang in Bronx converted himself and his followers into the non-violent group of Zulu Nation. Of this transition period Steven Hagar writes, "For over five years the Bronx had lived in constant terror of street gangs. Suddenly, in 1975, they disappeared almost as quickly as they had arrived. This happened because something better came along to replace the gangs. That

The position of non-executive director Essay Example | Topics and Well Written Essays - 1000 words

The position of non-executive director - Essay Example The researcher of the current paper states that there is no distinction made between the responsibilities of a non-executive director and an affiliated director. According the United Kingdom company law, however, both have distinct roles while fulfilling their responsibilities. The affiliated director is an employee of a company and is given an executive position and authority to involve in the day to day business operations of the company; on the other hand, the non-executive director is not an employee of the company; consequently, he or she does not possess an executive position or executive authority similar to the executive position or executive authority extended to the affiliated director. In addition to that, the affiliated director receives salary or remuneration for his or her services performed for the company; on the other hand, the non-executive director charges fees for providing his services for the board. Fundamentally, the functions of the non-executive directors are to provide a creative contribution to the board with the provision of objective criticism. Also, the non-executive directors are required to ponder over the board matters and avoid straying into the executive direction, which is the role of the affiliated directors. And, at the same time, the affiliated directors involve and carry out the executive decisions for the company on day to day basis in contrast to the function of the non-executive director. ... Consequently, the Sarbanes-Oxley 2002, in the United States, and Higgs Review of Non-Executive Directors in 2003, in the United Kingdom, revitalized the role of the non-executive director and gave more clarity to the participation and contribution of the non-executive director. Dispersed and concentrated ownership Particularly, in the United States and the United Kingdom, the dispersed ownership, which is also identified with the term â€Å"outsider systems† (Maher and Andersson, 1999), is featured with relatively high turnover along with widely dispersed share ownership; in the dispersed ownership, a more equitable distribution of information and a considerable emphasis is given to the protection of the shareholders rights and, especially, those of minority investors. On the other hand, concentrated ownership, also known as insider systems, have features such as the presence of ownership concentration or concentration of voting power in a few hands along with a multiplicity o f corporate holdings and inter-firm relationships. The specific examples, denoting the concept of concentrated ownership, include familial control, banks, holding companies and other non-financial institutions. Both types of ownerships offer different sorts of advantages. The dispersed ownership provides the benefits such as extended liquidity of stock; as a result, the investors can easily avail the better risk diversification possibilities; and, at the same time, the corporate governance framework in the dispersed ownership encourages the use of public capital markets (OECD, 1999); on the other hand, the problems such as supervision and monitoring of management, which remains to be a point of high tension in

Madeleine Essay Example | Topics and Well Written Essays - 1500 words

Madeleine - Essay Example The talks with the prostitutes in her neighborhood started altering Madeline morals. However, she moved to St. Louis to live with a friend while she was seventeen. She began to work in a factory but realized she was pregnant after working for a few months. She thus ran away from the friend’s house and moved into a brothel within Kansas since she could not support herself financially. To hide her identity, she invented the name Madeleine Blair. She later lost her baby and almost managed to avoid being engaged in sex trade when she migrated to Chicago. In Chicago, she started her life working in a department store. However, the salary is meager and she could not support herself. She ended up getting back to prostitution. Therefore, the major reason why Madeleine got into prostitution was the unplanned pregnancy. When she realized she was pregnant, she was ashamed of herself and left her friend’s house. Since she had no means to support herself she ended up getting into pr ostitution. Another reason that led Madeleine get into prostitution was her early exposure to talks regarding prostitution. She had lived in environments where prostitution was considered a lesser vice. Therefore, she easily got into the sex industry when she was compelled by her financial needs. Although she was aware of the existence of sex industry, she had tried to avoid being a prostitute by searching for a noble job since she wanted to retain her respect. However, the dire need for money and her condition of being pregnant drove her into the industry. Alter some time, her desire for money increased making it hard for her to leave the sex industry. She started migrating from brothel to brothel and ended up establishing her own brothel in Canada. 2) What does her story tell us about life during the late Gilded Age? How was she affected by industrialization, urbanization, rural decline, and the social problems associated with these transformations? In the Autobiography, Madeleine approves that the sex industry was of great economic benefit to the western countries. Madeleine considers prostitution as the only way that women could contribute to economic growth. Even the authorities and most people in Canada viewed sex industry as important in enhancing economic growth. Men considered brothels as crucial and would even go to nearby town in search of sex if there were no brothels in their locality. As industrialization progressed, men started earning better salaries. Most of them spent part of their salaries to pay for sex. This demonstrates that industrialization contributed to increase in prostitution. Madeleine describes her brothel as one that constituted an important social and economic component. It fulfilled the needs of the working class (Anonymous 180-184). To the girls who worked in the brothel, it was their source of income hence a form of employment. Moreover, the local municipal authorities greatly benefited from the bribes that Madeleine gave the m. The common people viewed prostitution as an important component of the local economy that was beneficial to all. Women could get employment, the authorities made profits, and men had some place to spend their leisure time. Therefore, people viewed brothels as institutions as important sector of the economy that enhanced exchange of money. With industrialization, there was increased number of women in urban centers. To them, prostitution was a noble way of earning

Peter Enterprises Essay Example | Topics and Well Written Essays - 750 words

Peter Enterprises - Essay Example An income statement represents a company’s activity or performance over a period of time. The income statement is intended to provide investors an accurate depiction of the company’s profitability over the period of time (in this case 1 year). This includes mainly the sales and cost figure of the company over the period of time. Cost which are capitalized are included in the category of either depreciation or amortization expense. The income statement is generally full of accounting assumptions; fundamentally the matching principle. The matching principle dictates that the revenues of the company should be matched with the expenses incurred during the period. Any accrued sales (Credit Sales) or expense is accounted in the income statement. Earnings from the income statement are essential criteria when investors evaluate or opt for a company to buy its share. It is earning power of the company which lifts its value and attracts the investor about the profitability of the company. In the case of Peter enterprise, it has generated a net profit of  £444,400 which is 14.79% of the sales. This implies that the net profit margin is 14.79% which is promising; however the company is profitable but we cannot jump into any conclusion unless we compare it with the industry standards for the particular year or a company which has risk similar to the Peter enterprises.

We can determine through balance sheet that how much financially strong and economically efficient a company is. It shows how much the company owns or how much money is owed by it. The assets are financed by either debt or equity and the balance sheet can reveal important information about it. We can compute a lot of ratios using the numbers in balance sheet and compare them with the industry standards. The most common ratios are liquidity, solvency, and profitability and efficiency ratios. A balance sheet can explain how the company is being managed. For instance, a high day on receivable implies that management is not efficient in collecting money. This impacts cash flow cycle and can cause liquidity problems for the organization. Furthermore, Solvency ratios such as the Debt/Equity ratio can provide an important insight to creditors to whether grant a loan to the organization or not. It also gives an insight to shareholders about the current worth of the company. An analysis of Peter’s balance sheet shows that it has a very high Debt/Asset ratio which is equivalent to 70%.

Human Services Essay Example for Free

Human Services Essay What needs do each agency meet and what demographic does each agency serve? The department of social services caters to anyone who in in need of assistance as long as basic requirements are met. The DSS mainly caters to women and children .This resource helps with food through a program named SNAP which stands for Supplemental Nutrition Assistance Program. The main role of this service is to supplement the incomes of the people who are having issues providing food for their family. This is done by Social services issuing an electronic benefit card also referred to as EBT card to distribute stamps on a monthly basis until the family is able to provide for their family with no assistance. They having other programs in place to assist with the needs of child care and some clients’ qualify to receive a cash allowance on a monthly basis until the family no longer qualify for the benefit. The program is a federal mandated program put into place to assist the country people that are vulnerable to having a poor quality of life. The other agency that was selected was CAASTL this program is very similar to the department of social services but on a much smaller scale. The Community action agency does not off monthly benefits for food and living expenses. However they do have food pantry that is used to help family eat healthy meals and they offer assistance with utility instead of issues out a monthly allowance. This service mainly cater to families with small children and elderly people in need of assistance. This program was put in place to assist with need of the people who lived in the county and did not qualify for services which were located in the city. Both agencies are there to help people that are in need the department of social services has more funding that CAASTL because it is a program that only receives funds to help pay for resources that would be used to assist people living in that community Click the Assignment Files tab to submit your assignment.

Major Trends Which Affect Microprocessor Information Technology Essay

Major Trends Which Affect Microprocessor Information Technology Essay In the first section I selected the question about Memory Management Unit of Linux operation system. In this section I described the strategies and mechanism used by Memory Management, problems faced by these techniques and solutions to overcome it. In the section number two I chose the question about microprocessor. This question discussed how microprocessors work, major trends affecting to their performance, differences between microprocessors design goals for laptops, servers, desktops and embedded systems. 2 Section1: Linux Operating System Introduction Linux, one of the free open source operating system does sufficient memory management activities to keep the system stable and users demand for errors free. As processes and threads executes, they read instructions from memory and decode it. In such act, instructions would be fetched or store contents of a location in a memory. Then, the processor would execute the instructions which in either way the memory would be accessed in fetching instructions or storing the data. Linux uses a copy-on-write scheme. If two or more programs are using the same block of memory, only one copy is actually in RAM, and all the programs read the same block. If one program writes to that block, then a copy is made for just that program. All other programs still share the same memory. Linux handles memory in such a way that when RAM is not in use, the operating system uses it as disk cache. Below diagram illustrate a brief overview of Linux operating system. C:UsersuserDesktopimages.jpg 3 Memory Management The term memory management refers to the one of the most important parts of the operating system. It consider in provision of memory-related services to applications. These services include virtual memory (use of a hard disk or other non-RAM storage media to provide additional program memory), protected memory (exclusive access to a region of memory by a process), and shared memory (cooperative access to a region of memory by multiple processes). Linux memory management does use the platform of Memory Management Unit which translate physical memory addresses to liner ones used by the system and page fault interrupt are requested when the processor tries to access to memory that is not entitled to. Virtual Memory Virtual memory of Linux is using a disk as an extension of RAM therefore that the effective size of convenient memory grows respectively. The kernel will write the substance of a currently dormant block of memory to the hard disk so that the memory can be used for another function. When the original contents are necessary again, they are read back into memory. This is all made completely transparent to the user; programs running under Linux only see the larger amount of memory available and dont notice that parts of them reside on the disk from time to time. Obviously, reading and writing the hard disk is slower (on the order of a thousand times slower) than using real memory, so the programs dont run as fast. The part of the hard disk that is used as virtual memory is called the  swap space. Virtual memory system consist of all virtual addresses not physical addresses. These virtual addresses are transformed into physical addresses by the processor based on information held in a set of tables maintained by the operating system. To make this conversion easier, virtual and physical memory are shared into handy sized pieces called pages. These pages are all the same size, if they were different size, the system would be very hard to administer 4 The schemes for Memory Management The simplicity of Linux memory model facilitates program implementation and portability in different systems. There exist two schemes for implementation of memory management in Linux; 1.Paging 2.Swapping Paging Demand Paging Currently, saving is done using physical memory by virtual pages when compiling a program. In latter case when a program runs to query a database, not all database will respond, but only those with data records to be checked. For instance a database request for search query will only be loaded and not database with programs that works to add new records. This is also referred to as demand paging. The purpose of using demand paging is to load performing images into a process of virtual memory. Every time when a command is accomplished, the file containing it is opened and its contents are displayed into the processs virtual memory. Memory mapping is executed by modifying the data structure which is describing this process. Even so the rest of the image is left on disk ,only the first part of the image is actually sent into physical memory. Linux uses memory map to identify parts of image to load into memory by generating page faults as the image executes. 5 C:UsersfoxDesktopmmu-vs-iommu-memory.png Page Faults Page fault exception are generated when a process tries to access an unknown page to memory management unit. The handler goes further in examining the currently running process`s memory information and MMU state, then determines whether the fault is good or bad. As good page faults cause the handler to give more memory to the process, the bad faults invoke the handler to terminate the process. From good page faults are expected behaviour to whenever a program allocates a dynamic memory to run a section of code, write a for the first time a section of data or increases its stack size. In such a case when a process tries to access this newly memory, page fault is declared by MMU and the system adds a fresh page of memory to the process`s table. The interrupted process is the resumed. In cases where a process attempt to access a memory that its doesnt own or follows a NULL pointer then bad faults occur. Additionally, it could also be due to bugs in the kernel in which case the handler w ill print an oops information before terminates/killing the process. 6 Swapping Linux separates its physical RAM (random access memory) into pieces of memory called pages. The process of Swapping is accomplished by copying a page of memory to the preconfigured space on the hard disk, known as a swap space, to exempt that page of memory. The combined sizes of the physical memory and the swap space is the amount of virtual memory available. Swapping is done mainly for two reasons; One is insufficient memory required by the system when physical memory is not available. The kernel does swaps out the less used pages and supply the resources to currently running processes. Second, a significant number of the pages used by an application during its start-up phase may only be used for initialization and then never used again. The system can swap out those pages and free the memory for other applications or even for the disk cache. Nevertheless, swapping does have a disadvantage. If Compare with memory, disks are very slow. For example, memory speeds are measured in nanoseconds, but disks are measured in milliseconds, so admittance to the physical memory can be significantly faster than accessing disk. It depends how often swapping occurs, if it happens frequently your system will be slower. Sometimes excessive swapping or thrashing occurs where a page is swapped out and then very soon swapped in and then swapped out again and so on. In such situations the system is struggling to find free memory and keep applications running at the same time. In this case only adding more RAM will help. There are two forms of swap space: the swap partition and the swap file. The swap partition is a substantive section of the hard disk which is used only for swapping; other files cannot locate there. A special file in the file system which stands amongst your system and data files called a swap file. 7 Problems of virtual memory management in Linux There are several possible problems with the page replacement algorithm in Linux , which can be listed as follows: à ¢Ã¢â€š ¬Ã‚ ¢ The system may react badly to variable VM load or to load spikes after a period of no VM activity. Since the Kswapd, the page out daemon, only scans when the system is low on memory, the system can end up in a state where some pages have reference bits from the last 5 seconds, while other pages have reference bits from 20 minutes ago. This means that on a load spike the system have no clue which are the right pages to evict from memory, this can lead to a swapping storm, where the wrong pages are evicted and almost immediately after towards faulted back in, leading to the page out of another random page, etc. à ¢Ã¢â€š ¬Ã‚ ¢ There is no method to prevent the possible memory deadlock. With the arrival of journaling and delay allocation file systems it is possible that the systems will need to allocate memory in order to free memory, that is, to write out data so memory can become free. It may be useful to introduce some algorithm to prevent the possible deadlock under extremely low memory situation. Conclusion All in all, Linux memory management seems to be effective than before and this is based on the assumption that Linux has less applications that it runs as to compared to windows machines which has more users and more applications. Beside, the system may react badly to variable VM load However, regular updates from Linux has managed to lessen the bugs. Swapping does require more disk memory in case the physical memory is insufficient to serve more demanding applications and if the disk space is too low the user runs the risk of waiting or kill other process for other programs to work. Additionally, resuming the swapped pages may result into corrupted data, but Linux has been in upper hand to solve such bugs. 8 Frequently Ask Questions What is the main goal of the Memory Management? The Memory Management Unit should be able to decide which process should locate in the main memory; should control the parts of the virtual space of a process which is non-core resident; responsible for monitoring the available main memory and for the writing processes into the swap device in order to provide more processor fit in the main memory at the same time. What is called a page fault? Page fault appear when the process addresses a page in the working set of the process but the process is not able to locate the page in the working set. To overcome this problem kernel should updates the working set by reading the page from the secondary device. What is the Minimum Memory Requirement? Linux needs at least 4MB, and then you will need to use special installation procedures until the disk swap space is installed. Linux will run comfortably in 4MB of RAM, although running GUI apps is impractically slow because they need to swap out to disk. 9 Section 2: Microprocessor Introduction Microprocessor incorporates all or most of the functions of Central Processor Unit (CPU) on a single integrated circuit, so in the world of personal computers, the terms microprocessor and CPU are used interchangeably. The microprocessor is the brain of any computer, whether it is a desktop machine, a server or a laptop. It processes instructions and communicates with outside devices, controlling most of the operation of the computer. How Microprocessors Work Microprocessor Logic A microprocessor performs a collection of machine instructions that tell the processor what to do. A microprocessor does 3 main things based on the instructions: Using its ALU (Arithmetic/Logic Unit), a microprocessor is able to perform mathematical operations like addition, subtraction, multiplication and division. A microprocessor is able to move data from one memory location to another. A microprocessor is able to make decisions and jump to a new set of instructions based on those decisions. 10 The following diagram shows how to extremely simple microprocessor capable of doing of 3 jobs. The microprocessor contains: An address bus that sends an address to memory A data bus that can sends data to memory or receive data from memory A RD (read) and WR (write) line to tell the memory whether to set or get the address A clock line lets a clock pulse sequence the processor A reset line that resets the program counter to zero and restarts execution 11 Here the explanation of components and how they perform: Registers A, B and C are kind of latches that made out of flip-flops The address latch is just like registers A, B and C. The program counter is a latch with the extra capacity to increment by 1 when or reset to zero it is needed. Major trends which affect microprocessor performance and design Increasing number of Cores: A dual-core processor is a  CPU  with two processors or execution cores in the same  integrated circuit. Each processor has its own  cache  and controller, which enables it to function as efficiently as a single processor. However, because the two processors are linked together, they can perform operations up to twice as fast as a single processor can. The Intel Core Duo, the AMD X2, and the dual-core PowerPC G5 are all examples of CPUs that use dual-core technologies. These CPUs each combine two processor cores on a single silicon chip. This is different than a dual processor configuration, in which two physically separate CPUs work together. However, some high-end machines, such as the PowerPC G5 Quad, use two separate dual-core processors together, providing up to four times the performance of a single processor. 12 Reducing size of processor Size of the processor the one of the major trend what is affecting to the processor in last years time. When the processor becoming small there will be many advantages like it can include many cores to a processor, it will protect energy, it will increase its speed also. 45nm Processor Technology Intel has introduced 45nm Technology in Intel Core 2 and Intel Core i7 Processor Family. Intel 45nm High-K Silicon Processors contain Larger L2 Cache than 65nm Processors. 32nm ProcessorTechnology At research level Intel have introduced 32nm processor (Code Name Nehalem- based Westmere) which will be released in 2nd quarter of 2009 Energy saving Energy is one of the most important resources in the world. Therefore we must save and protect it for future purpose. The power consumption in microprocessor would be one of the major trends. For instance, Intel Core 2 family of processors are very efficient processor, they have very intelligent power management features, such à Ã‚ °s, ability to deactivate unused cores; it still draws up to 24 watts in idle mode. 13 High speed cache and buses In Past year Microprocessor Manufactures like Intel has introduced new cache technologies to their processors which can gain more efficiency improvements and reduce latency. Intel Advanced Smart Cache technology is a multicore cache that reduce latency to frequency used data in modern processor the cache size is increased up to 12MB installing a heat sink and microprocessor 14 Differences between Microprocessors Servers Originally the microprocessor for server should give uninterrupted time and stability with low power consumption and less resources allocating processor for System Cache. Thats why most of the time they use Unix and Linux as the Server based operating systems, because they take less amount of hardware resources and use effectively so the heat which dispatches from the processor is less and the heating would be less. Desktop Processors The desktop microprocessors are a bit different from server microprocessors, because they are not very much concerned of power consumption or use less resources of Operation system. The goal of Desktop microprocessors is to deliver as much performance as possible while keeping the cost of the processor low and power consumption within reasonable limits. Another important fact is out there, it is most of the programs which are being used in desktop machines are designed to do long time processor scheduling jobs like rendering a high definition image, or compiling a source file. So the processors are also designed to adopt those kinds of processing. Laptop Processor The CPU produces a lot of heats, in the desktop computers there are a systems of fans, heat sinks, channels and radiators that are uses to cool off the computer. Since laptop has small size, and far less room for any cooling methods, the CPU usually: Runs at a lower voltage and clock speed (reduces heat output and power consumption but slows the processor down) Has a sleep or slow-down mode (when the computer is not in use or when the processor does not need to run as quickly the operation system reduces the CPU speed) 15 Embedded Microprocessors Most of the embedded devices using Microcontrollers instead of separate Microprocessors; they are an implementation of whole computer inside a small thumb size chip called Microcontroller. These microcontrollers are varying its performance due to battery consumption and Instruction length issues. Most of them are designed using RISC architecture to minimize the complexity and the number of instructions per processor. Embedded device processors have high speed potential but the problem they are having is high power consumption and heating. Conclusion Current technology allows for one processor socket to provide access to one logical core. But this approach is expected to change, enabling one processor socket to provide access to two, four, or more processor cores. Future processors will be designed to allow multiple processor cores to be contained inside a single processor module. 16 Frequently Ask Questions: 1. How does the operating system share the cpu in a multitasking system? There are two basic ways of establishing a multitasking environment; times lice and priority based. In a a times lice multitasking environment each application is given a set amount of time (250 milliseconds, 100 milliseconds, etc) to run then the scheduler turns over execution to some other process. In such an environment each READY application takes turns, allowing them to effectively share the CPU. In a priority based environment each application is assigned a priority and the process with the highest priority will be allowed to execute as long as it is ready, meaning that it will run until it needs to wait for some kind of resource such as operator input, disk access or communication. Once a higher priority process is no longer ready, the next higher process will begin execution until it is no longer ready or until the higher priority process takes the processor back. Most real-time operating systems in use today tend to be some kind of combination of the two. 2.What is a multi-core? Two or more independent core combined into a single package composed of a single integrated circuit is known as a multi-core processor. 3. What is the difference between a processor and a microprocessor? generally, processor would be the part of a computer that interprets (and executes) instructions A microprocessor, is a CPU that is in just one IC (chip). For example, the CPU in a PC is in a chip so it can also be referred to as microprocessor. It has come to be called a microprocessor, because in the older days processors would normally be implemented in many ICs, so it was considered quite a feat to include the whole CPU in one chip that they called it a Microprocessor 17

Could biotechnology solve food shortage problem? Essay -- Hunger, FAO,

Food shortage is a global problem and tragedy of the world. There are almost 1 billion people who suffer from incessant hunger. Every 6 seconds a child dies from hunger (Food and Agriculture Organization of the United Nations, 2010). It is unacceptable that number of hungry people is so high. Hunger is continuous, serious and structural problem, which could not be solved in one day. Different world organizations, scientists, economists, politics care about undernourished people and try to find ways for reducing their number. Fortunately, according to FAO in 2010 noted the reduction of hunger of 9.6 percent from 2009 level. Most of all it decreased in Asia, there are 80 million less hunger people. Africa is the only area where poverty and hunger are going on to increase. The number of Africans living on less than one dollar per day has increased 50 percent for the last fifteen years (Paarlberg, 2008). 239 million people of sub- Saharan Africa suffer from malnutrition (FAO, 2010). It is 25.8% of all hungry people in the world. Why are so many Africans still hungry? What are the reasons of their poverty? In general, main reasons are political instability, poorly developed economy, nonproductive farming, etc, but each country has special details. This project will investigate whether subsistence farmers of sub-Saharan Africa can use biotechnology’s advantages. Economy based on subsistence agriculture. For solving malnutrition problem, we need to solve poverty problem, because if people will have jobs, safety place to live, and education they get enough money for food. Now Africa is poor, economy of sub-Saharan Africa’s countries based on agriculture, applying for almost 45% of GDP, and 85% of total employment and most of pe... ...ieve new level of economy when sub-Saharan Africans will work and have enough food for stable and safe lives. Of course, advantages of biotechnology is very useful for enhancing product’s quality, nutrition , for protecting parts of plant like root from different diseases, but for solving food shortage in Sub-Saharan Africa it is essential to solve economical problems. In example of some countries it is clear to notice that food shortage is consequence of poverty. To sum up, sub-Saharan Africa need help from abroad – infestations. Africa has good potential; there are a lot of minerals, precious metals. Also there are good conditions for tourism industry. For example, Ethiopia could develop tourism industry. Wild nature, rich history, ancient towns attract people around the world. Thinking about future it is important to invest to qualified education.

African American Hardships Essay -- African American Studies

African American Hardships During pre-colonial African kinship and inheritance, it provided the bases of organization of many African American communities. African American men were recognized for the purpose of inheritance. They also inherited their clan names based on their accomplishments, as well as other things when one decease. Land was not owned in many parts of Africa during the pre-colonial period. It was yet held and distributed by African American men. Access to the land by women depended on their obligations or duties within the gendered division of labor. Agriculture was the job of many African women. Men believed in having several wives that would all work together as farm workers and do whatever duties necessary as required. Africa is considered to be a multi-lingual country. There are eleven officially recognized languages their, many of which are often spoken but not widespread. English is generally understood across the country. It is one of the eleven common spoken languages but it only ranks 5th out of the eleven spoken languages. During the 15th and the 19th century, major changes had happened to the African and North American continents. Europeans ventured to Africa where they began a trans-Atlantic slave trade. Many Africans were taken as free people and then forced into slavery in South America, the Caribbean and North America. This slave trade had brought about a different type of racism. It was the color of your skin that determined whether a person would be a free citizen or be enslaved for life. This slave trade also devastated African lives and their heritage. Some slaves were sold and traded more than once, often in a slave market. Families were torn apart, children hysterically cried while t... ...t units to serve in the civil war. Most blacks did not care about what the issues of the war was. They joined because it provided a better income which was an alternative way of making money compared to the poorly paid domestic labor that most blacks had endure. The civil war resulted in the 13th Amendment of the Constitution which abolished slavery all together. Although black soldiers fought in the war which eventually ended slavery, they still did not have civil rights. The whites did not want to share political power with African Americans. This had brought about the 14th and 15th Amendments to the Constitution. African Americans were now guaranteed civil rights. This change opened doors for African Americans so that they can progress and excel in the political system. Public schools were now established and access to jobs outside domestic labor was now available.

Mice and Men Essay

Hopes and dreams help people to survive even if they never become real. How far is this true for the characters in Of Mice and Men? Support your ideas with details from writing. Of Mice and Men is a novel written by John Steinbeck here two itinerant ranch workers, George Milton and Lennie Small share the same American dream. The story is set in California, at the beginning of the 20th century, during the despotic Great depression where dreams and hopes were the only purposes of living. Desires and aspirations are significant in Of Mice and Men. In a world where it is impossible to have a friend, to talk or to listen to somebody, the hope of a dream coming true is the only thing that can keep George, Lennie and Candy going on, surviving in that hostile environment. George Milton fantasizes about having â€Å"a big vegetable patch and a rabbit hutch and chickens†, helping him to withstand in his precarious situation. The crux of dream for George is not the absence of work, or the easy living, or even having money, it is simply grounded in having for the first time of his life a place to belong. This dream is a driving force for George, a powerful motivation which persuades him that all of these hard working days are not worthless. In fact, George â€Å"said thoughtfully, Look, if me an’ Lennie work a month an’ don’t spen’ nothing, we’ll have a hundred bucks†. This shows how George is ready to work hard in order to obtain this sum of money. Moreover, the word â€Å"thoughtfully† imparts that George is deeply thinking of working hard, thus portrayed as extremely motivated. The dream is perceived as reward, an indemnity for all the troubles he has already endured in his life. However, George doesn’t believe entirely in the dream. The protagonist knows that there is a very few chances for the dream to come true. Thus, it is not the dream but the hope of the dream which stimulates Lennie’s companion. Moreover, George uses this dream to keep Lennie in check. For instance, George promises Lennie to ‘tend the rabbits all right. ‘Specially if he remembers as good as that†. Here, George manipulates cleverly the dream in order to captivate Lennie’s attention and to have him remember not to â€Å"say a word† in front of the boss. The dream turns from a motivating force into a reward for Lennie’s effort. Lennie Small yearns for ‘livin’ off the fatta the lan, an’ have rabbits†. From his point of view, this dream is not a simple dream, it’s a hope. A hope in which he could â€Å"tend the rabbits† and all his other favourite animals. Despite the fact that George’s and Lennie’s dream is identical, their perceptions are diverging. Lennie’s approach is much more childish, more fantastical and unrealistic. Besides, Lennie is extremely fond of his dream and believes extremely in it. Lennie is not feeling as â€Å"if† but â€Å"when† The absence of conditional in Lennie’s speech reveals that he really believes in this dream. Furthermore, Lennie knows by heart and can recite, word by word his most precious wish. This shows that Lennie has propably heard the same thing over and over again. In deed, as the protagonist is mentally challenged, the fact that he can remember this dream demonstrates how devoted he is to this wish. Moreover, when talking about that specific desire, Lennie is constantly interrupting George in his speech. At this moment, Lennie’s attitude and behaviour portrays a trancelike character, escaping successfully in his ideal world. Furthermore, after a savage and wild fight with Curley, Lennie’s first question to George is: â€Å"I can still tend the rabbits, George? †. Thus, Lennie appears to be obsessed with his dream, even after a ferocious assault. This shows how Lennie is attached to his main goal. In addition, Lennie’s attachment is also revealed when the protagonist is ready to â€Å"break their God damn necks and smash ‘em with a stick†. This serious threat demonstrates Lennie’s determination to achieve his desire and also how virulent he can be. Anything that’s in the dream’s way will endure Lennie’s barbarity, maybe the death sentence. Moreover, Lennie is only intimidating imaginary cats. This points out that Lennie is extremely resolved to attain his wish, even ready to surpass a fictitious obstacle. This extract is therefore used to foreshadow Curley’s wife tragic fate. In deed, Candy’s wife is perceived since her first apparition as an obstruction to the dream. George orders Lennie to â€Å"keep away from her†. Therefore, if Curley’s wife is susceptible to make the dream impossible to come true, Lennie can easily kill her, and Curley’s wife will turn out to be murdered by Lennie. Despite Lennie’s undisputable faith, his dream turns out to be an unattainable escape. However, the protagonist manages to flee his miserable life thanks to his dream. Candy’s dream is to join George’s and Lennie’s plan, in order to flee his loneliness. Candy’s financial contribution increases the probability for the dream to come true. As a consequence, George, Lennie and Candy â€Å"fell into silence. They looked at one another, amazed. This thing they had never believed in was coming true†. This quote suggests that this precise moment represents the crux of the protagonists’ dreams. The word amazed implies a serious fascination where the three men realize at the same time the possibility for their dream to come true. Moreover, ‘they sat still, all bemused by the beauty of the thing, each mind was popped into the future when this lovely thing should come about†. The quotation shows how engrossed and enthralled the three men are. Furthermore, the adjective bemused suggests how motionless and quite are the three man, astonished and perplexed about the possibility for the dream to come true. However, one could see that Candy’s participation spoils the dream of the farm by making it a genuine possibility rather than an on going and eternal wish. We are suddenly asked weather the dream isn’t better off as a dream, something they can believe and visualize that’s bigger and better than any other reality. In conclusion, hopes and dreams help George, Lennie and Candy to survive even if they never become real. The farm is a dream for George, a hope for Lennie and even a plan for Candy that help them survive in their miserable lives.

Discipline in High School and Elementary Education

When it comes to special education, discipline is a major concern in this area because many students are incessantly being expelled for their behavior issues that are caused by their disabilities. With the previous law students were excluded from school and received long suspension time because of their behavioral problems but when the new law was passed in 2004 students that are disable, is entitle to a free appropriate education under the Individuals with Disabilities Education Act (IDEA) and can no longer be expel from school if their behavior is due to their disability.With the new law, students can no longer be suspended for more than 10 days during a school term for behavioral issues and 45 days for weapon and illegal drugs. A Functional Behavioral Assessment (FBA) should be included within the special need students Individualized Education Plan (IEP) at the beginning of each school year so that the general education teachers is aware of the students behavioral problems and is able to handle them before the student get out of hand and the other students learning is disruptive.If students know what is expected of them in the beginning, I believe that they will try to keep their behavior under control especially when they are in a more controlled and structure classroom. During the interview process, I learned that both high school and elementary education follow the same guidelines and rules when it comes to discipline special needs students; they have to follow the laws under Individuals with Disabilities Education Act 2004.The only difference that I reconginzed is that high school administrators feel that special need students at their school should be comfortable with their disabilities and have their behavioral under control because they have dealt with many issues throughout their elementary education and had various behavorial intervention plan in place which are various techniques that are used to help alleviate their behavior. With special educatio n teachers being a high demand now, newteachers should be well informed on how to discipline special needs students. Mrs. Davis expressed, issues that frequently occur with special needs students will be, if their wrongdoing is a direct manifestation of the student disability and new or experience teachers should be aware if the student disability is affecting their behavior. Since discipline is a major issue that appears to occur in schools due to special education students being included into regular education classrooms.Students tend to act out because they are not on the same level as their non-disable peers and feel as though they are not able to complete the same course work and receive a passing grade therefore they begin to disrupt the class instead of asking for help when it is needed. I can understand the student frustration when they are not able to answer questions or other students make fun of them because they could not get the correct answer.These students are in a ma instream classroom with their peers but are not on the same reading level as them and it is difficult for them to participate in class and feel as if they are up to part (T. Davis, personal communication, December 16, 2013). Ms. James stated that discipline issues that occur with special needs students in her school are students that are emotionally disturbed. These students disrespect their authority figures, fight other students and it even goes so far as them threatening to harm teachers and other students (S.James, personal communication, December 18, 2013).The court case that influence the school district is Honig v. Doe, the court ruled that students with disabilities can not be excluded from school for any misbehavior that is disability related but the educational service could cease if the misbehavior is not related to the disability (wrightlaw, 2011). We discussed the challenges that administrators and teachers face related to special education students. According to Mrs.Da vis a special need student has a plan of action in place which drives his/her instructions, if special need students commit serious wrongdoings which is not a manifestation of his disability then he/she will be reprimanded; the same as a regular education student (Ms. Davis, 2013). Doe v. Koger (1979) court case influence the school district because the court implied that students with disabilities could be expelled when there was no relationship between their misconduct and their disabilities, a perspective that became known as the manifestation of the disability doctrine (Osborne, 2007).Ms.James stated that this is a big challenge for administrators and teachers because special needs students do not receive the same disciplinary actions as regular students although they committed the same misconduct. It is unfair that their learning and others students learning is being disruptive and teachers have to accept their inappropriate behavior because they are protected under IDEA (S. Ja mes, 2013). The disciplinary procedure is perplex between the two groups; some individual may think that it is fair for the two groups to received different action against them for their misbehaving in the classroom but Mrs.Davis think that disciplinary action is demanding when managing these two groups because it require the teachers to stay abreast of all of the individuality of the special need student so that instructional as well as behavioral problems maybe avoided by quick adjustments in the classroom. On the other hand, Ms. James felt that special needs students are not sent to the office quicker than regular education students. Teachers have to deal with their behavior and try different positive behavior techniques with them.Some students are not aware of disciplinary decisions and actions between both groups of students, special needs students do not realize that they can not be expelled from school. According to Osborne, the court did not leave school officials without re course; it added that they could suspend students with disabilities for up to 10 days if they posed an immediate threat to the safety of others. I also learned that it is imperative that the parents are involved and provided with procedural safeguard information which identifies their child’s rights related to special education under the Individuals with Disabilities Education Act.The interview goes on to discuss how parents react to how their children are being punished different from a special need student, they are not happy with the rules because they feel that every student should received the same punishment regardless. We also discussed the decision that the district makes and the ladies stated that the district stands behind Tribunal’s decision and the special education director is responsible for training.

What Is Cybercrime?

Cybercrime, or PC arranged wrongdoing, is wrongdoing that includes a PC and a network. The PC may have been utilized in the commission of a wrongdoing, or it might be the target. Cybercrimes can be characterized as: â€Å"Offenses that are perpetrated against people or gatherings of people with a criminal thought process to purposefully hurt the notoriety of the person in question or cause physical or mental damage, or misfortune, to the casualty straightforwardly or in a roundabout way, utilizing current media transmission systems, for example, Web (systems including however not restricted to Visit rooms, messages, see sheets and gatherings) and cell phones (Bluetooth/SMS/MMS)†. Cybercrime may undermine a man or a country's security and monetary health. Issues encompassing these kinds of violations have turned out to be prominent, especially those encompassing hacking, copyright encroachment, unjustifiable mass-reconnaissance, sextortion, youngster erotic entertainment, and kid grooming. There are additionally issues of protection when private data is blocked or unveiled, legitimately or something else. Debarati Halder and K. Jaishankar additionally characterize cybercrime from the point of view of sex and characterized ‘cybercrime against ladies' as â€Å"Wrongdoings focused against ladies with a rationale to deliberately hurt the casualty mentally and physically, utilizing current media transmission systems, for example, web and versatile phones†. Universally, both administrative and non-state performers participate in cybercrimes, including secret activities, budgetary burglary, and different cross-outskirt violations. Cybercrimes crossing global outskirts and including the activities of no less than one country state is now and then alluded to as cyber warfare.TYPES OF CYBERCRIMEIDENTITY THEFT OR INVANSION OF PRIVACYCybercrime influences both a virtual and a genuine body, however the impacts upon each are unique. This wonder is clearest on account of fraud. In the Assembled States, for instance, people don't have an official personality card yet a Standardized savin gs number that has since quite a while ago filled in as a true recognizable proof number.INTERNET FRAUDPlans to cheat customers flourish on the Web. Among the most well known is the Nigerian, or â€Å"419,† trick; the number is a reference to the area of Nigerian law that the trick damages. In spite of the fact that this con has been utilized with both fax and conventional mail, it has been given new life by the Web. In the plan, an individual gets an email affirming that the sender requires help in exchanging an extensive aggregate of cash out of Nigeria or another far off nation. More often than not, this cash is as a benefit that will be sold, for example, oil, or a lot of money that expects â€Å"laundering† to cover its source; the varieties are interminable, and new specifics are continually being produced. The message requests that the beneficiary take care of some expense of moving the assets out of the nation as an end-result of accepting a considerably bigger whole of cash sooner rather than later. Should the beneficiary react with a check or cash arrange, he is informed that confusions have grown; more cash is required. After some time, casualties can lose a large number of dollars that are completely unrecoverable.ATM FRAUDPCs additionally make more unremarkable sorts of misrepresentation conceivable. Take the robotized teller machine (ATM) through which numerous individuals currently get money. With a specific end goal to get to a record, a client supplies a card and individual recognizable proof number (Stick). Crooks have created intends to capture both the information on the card's attractive strip and in addition the client's Stick. Thus, the data is utilized to make counterfeit cards that are then used to pull back assets from the clueless person's record.WIRE FRAUDThe INTER NATIONAL idea of cybercrime is especially apparent with wire extortion. One of the biggest and best-sorted out wire extortion plans was coordinated by Vladimir Levin, a Russian developer with a PC programming firm in St. Petersburg.FILE SHARING PIRACYThrough the 1990s, offers of minimized circles (Albums) were the real wellspring of income for chronicle organizations. In spite of the fact that theft—that is, the unlawful duplication of copyrighted materials—had dependably been an issue, particularly in the Far East, the multiplication on school grounds of reasonable PCs equipped for catching music off Cds and sharing them over fast (â€Å"broadband†) Web associations turned into the account business' most noteworthy bad dream. In the Unified States, the account business, spoken to by the Chronicle Business Relationship of America (RIAA), assaulted a solitary document sharing administration, Napster, which from 1999 to 2001 permitted clients over the Web access to music records, put away in the information pressure organize known as MP3, on other clients' PCs by method for Napster's focal PC. As per the RIAA, Napster clients frequently abused the copyright of account specialists, and the administration needed to stop. For clients, the issues were not all that obvious. At the centre of the Napster case was the issue of reasonable utilize. People who had bought a Compact disc were obviously permitted to tune in to the music, regardless of whether in their home stereo, vehicle sound framework, or PC. What they didn't have the privilege to do, contended the RIAA, was to make the Cd accessible to a huge number of other people who could make an ideal computerized duplicate of the music and make their own Compact discs.COUNTERFEITING AND FORGERYRecord sharing of licensed innovation is just a single part of the issue with duplicates. Another more unremarkable angle lies in the capacity of computerized gadgets to render about ideal duplicates of material ancient rarities. Take the conventional wrongdoing of forging.

Hans Zimmer Essay

This case study will explore the life and works of one of the most prominent and inventive film and music composers of modern times, Hans Zimmer. His extraordinary ability to span an extensively wide range of genres and formats with extreme competence is extremely influential and inspiring. Zimmer is a pioneer in his field, with his use of both electronic and orchestral elements within film scores. Zimmers success in creating the scores for some of the most celebrated films, and his ability to encapsulate in the music the overriding themes, and personalities of the characters in modern day cinema is what makes him so special. I have chosen to write on this subject as it is completely relevant to my interest in the field. This case study includes a discussion of the early life of Hans Zimmer, his entrance into the world of Hollywood composition, his influences and growth as a composer and leads to a more in-depth discussion of the work on his most current films, as well as a brief look at the studio and equipment he uses. Born in Frankfurt, Germany on September 12th 1957 Hans Florian Zimmer is acknowledged as one of the most pioneering, innovative, successful, influential and sought after composers in Hollywood today (IMDB, no date). His interest in music began at a very early age and he began playing the piano at the age of three, although he had little or no formal music education or training throughout his early life (Gillespie, 2001). Despite his lack of training, Zimmer knew he wanted to be a composer by the age of six and this coincided with an important event in the young Zimmer’s life; the death of his father. He is quoted as saying in an interview with CNN Worldbeat; â€Å"My dad died when I was six, that’s when I decided I was going to become really serious about music, because it was my refuge† (CNN Worldbeat cited by IMDB, no date). During his early teens his family moved all over Europe before settling in London when Zimmer was 14 years old. Throughout his childhood his passion for music meant he neglected his schoolwork and as a result was expelled from several different schools (Shelton, no date). After finally finishing school he began his professional music career by composing advertising jingles for Air Edel associates and playing in rock bands (Ankeny, no date). It was during this period that Zimmer found success as a member of The Buggles, an English new wave synthpop group, and had a hit single with ‘Video Killed the Radio Star’. It is said that this worldwide hit helped ‘usher in a new era of global entertainment as the first music video to be shown on MTV’ (IMDB, no date). His talent on the keyboard and synthesisers would continue to be significant throughout his career although this is perhaps the first event that might have suggested at the huge amount of success and appreciation he would go on to enjoy as a composer. Zimmer is known to have favoured the Moog synthesiser when performing and creating music for these groups, a preference that has endured the span of his career. It was also during this period that we see Zimmer first combining the use of computers with live music on stage with other successful groups (Shelton, no date). This combination has been a constant throughout Zimmer’s professional career and his talent in merging the two elements is part of what has earned him the success and appreciation he currently enjoys. The diversity of his talent is also seen in his ability to span genres such as new wave UK punk, as well as Spanish pop music. However, Zimmer would not remain a part of the pop scene for long. He felt inhibited by having to write in just one style of music and felt his creativity was restrained. It was at this time that he first went to work with Stanley Myers who began to teach him about scoring films (Shelton, no date). This partnership would prove to be a collaboration of great orchestral elements combined with the most up to date electronic instrumentation available (Abodos, no date). Zimmers technological fascination in these early years has proved influential in his later and most successful works. Perhaps it is this preoccupation with technology that has kept him at the forefront of composition. It could also be said that the use of both technological and traditional orchestral elements has ensured his popularity with all generations of audiences. It was with Myers that Zimmer co-founded the London based Lillie Yard recording studio (Wikipedia, no date). A demonstration of the combining of the elements mentioned above is showcased in their early works, an example of which is seen in the film ‘Moonlighting’ (1982). The fusion of moody undertones performed with synthesisers and clean orchestral pianos combine to create a dark, unnerving, suspenseful atmosphere in keeping with the films subject and the emotions portrayed by the characters. His talent for creating music spanning the genres of different films is also seen in this early collaboration with Myers. Further examples of this are his compositions for films such as ‘Success is the Best Revenge’ (1984) which is a drama and the films ‘Insignificance’ (1985) and the acclaimed ‘My Beautiful Launderette’ (1985) which have comedic elements and demand that a completely different atmosphere is created. For example, ‘My Beautiful Launderette’ features a much more upbeat electronic production with less orchestral elements as the subject matter of the film requires. From 1982 – 1987 Zimmer worked collaboratively on productions. It was not until the film ‘Terminal Exposure’ (1987) that Zimmer would produce his first solo-score (Wikipedia, no date), based heavily on electronic production encapsulating the 80’s pop culture era. His next collaboration with David Byrne and Ryuichi Sakamoto would lead to his first taste of Academy Award success – winning the Oscar for Best Original Score with the picture ‘The Last Emperor’ (1987). The theme tune of which combines influences from both traditional Western and Eastern cultures, again allowing him to experience new found inspiration for his future creations. At this time he also created one of his most durable works for the UK television game show ‘Going for Gold’, about which he was quoted in an interview with the BBC as saying ‘[it] was a lot of fun. It’s the sort of stuff you do when you don’t have a career yet’ (BBC, 2008). This demonstrated his levelheadedness despite his new found success. This is also another example of how Zimmer was able to span the genres of music composition whilst enjoying his work, which arguably has been crucial to his success. The next film score composed by Zimmer was the small budget movie ‘A World Apart’ (1988) about apartheid South Africa (Shelton, no date). This was his first excursion into composition for a movie set in Africa, perhaps leading to his continuing interest in this area (seen in his work on the later films ‘The Power of One’ (1992) and ‘The Lion King’ (1994)). The soundtrack to ‘A World Apart’ featured traditional African instruments such as African drums and shakers giving the soundtrack an authentic feel. At the same time, these are combined with powerful synthetic strings which strike emotion and also bring in a Western element, which mirrors the films subject. 4 – Word Count: 3459 Student no. 15735 The success of this soundtrack led to Zimmer’s involvement in the critically acclaimed film ‘The Rain Man’ (1988) after the Hollywood director Barry Levinson’s wife introduced him to Zimmer’s work (Wikipedia, no date). Zimmer would follow an individual process when composing; â€Å"It was a road movie, and road movies usually have jangly guitars or a bunch of strings. I kept thinking don’t be bigger than the characters. Try to keep it contained. The Raymond character doesn’t actually know where he is. He might as well be on Mars. So, why don’t we just invent our own world music, for a world that doesn’t really exist? † (Zimmer cited by Young, 2008). This allowed for the score to contain escapist, other-worldly elements reflecting the character played by Dustin Hoffman. The Rain Man’ (1988) was Zimmer’s first venture into Hollywood. The soundtrack was created by the use of a lot of digital synthesis from the Fairlight CMI which was able to do sampling as well as additive synthesis where Zimmer was able to draw his own wave forms. In 1989 the score was nominated for an Academy Award and won Best Picture (Shelton, no date). His success would only contin ue. He was approached by the director of ‘Driving Miss Daisy’ (1989) the score of which consisted mainly of synthesisers and samplers. The Roland MKS-20 synthesiser was used for piano sounds about which Zimmer jokingly quoted â€Å"It didn’t sound anything like a piano, but it behaved like a piano† (Zimmer cited by Wherry, 2002) showing the unpredictable nature of digital synthesis. Within the same month as ‘Driving Miss Daisy’ Zimmer also created the score for the film ‘Black Rain’ (1989). In involving himself with both these films which were of entirely different genres he felt that Hollywood would not be able to typecast him (Young, 2008). This is further evidence of Hans Zimmer’s drive to think outside of the box, never wanting to be constrained or restricted to create just one type of music. His broad horizons were demonstrated further in 1992 with the film ‘The Power of One’ where Zimmer expressed his thirst for gaining authentic samples and knowledge of different musical cultures by travelling to Africa and sampling indigenous choirs and traditional drums. He gained a police-record whilst in the country for his work on the film for being labelled as subversive (Wikipedia, no date). It was ‘Power of One’ that led to his first expedition into the world of animation with the 1994 film ‘The Lion King’ which followed the African theme. Zimmer originally created 48 different theme tunes for ‘The Lion King’ (1994) before he was happy with the outcome (Hans-Zimmer. com, no date, a), displaying his meticulous nature. It can be said that this contributed to the film’s success and it went on to win an Oscar for Best Original Score and Golden Globe awards (Ankeny, no date). The African drum and choir samples used in ‘Circle of Life’ (the theme tune for the film) convey authenticity, whilst the use of a Western vocalist meant that a Western audience could still identify with the track. This maintained its resonance with the films main demographic, and the score was later adapted into a Broadway musical. After years of orchestral development Zimmer went back to his roots of synthesis with the Grammy Award winning film ‘Crimson Tide’ in 1995. However, his success post-Lion King meant that the celebrity lifestyle was in danger of catching up with him and his first attempts at the composition for ‘Crimson Tide’ were described by its directors as ‘crap’ and ‘rubbish’ and Zimmer is quoted as saying that â€Å"reality came back really fast for him† (Zimmer cited by Young, 2008). In the following years Zimmer went on to work on the scores for many more successful films. It was in the 2000’s, however, with the postmodern preoccupation with film that he became involved with even higher budgeted Hollywood Blockbusters. The following discussions of his works will describe 5 – Word Count: 3459 Student no. 15735 in depth how Zimmer’s creative processes lead to an extremely effective way of making sound for movies. The first of these discussions will focus on the film ‘Gladiator’ (2000). It is important to note Zimmer’s preoccupation with imagery and how the sound will translate on screen. It can be said that rather than dictate with music, Zimmer will take elements from the scenes, the characters and aesthetics of the film to set up the tone. An example of this is seen in what is arguably the most iconic scene of the movie, set in a wheat field, which is extremely poetic. Zimmer argues that the music gives the artistic license to be so poetic (hans-zimmer. com, no date, a). He talks about the collaboration with the artist Lisa Gerrard on this scene, and describes this relationship as a meeting of minds, finding her to be a ‘true’ artist. This collaboration is clearly effective in evoking emotion as the guttural vocals by Gerrard coincide beautifully with the imagery. Whilst watching the movie, it is found that the same piece of theme music is used in different places and in scenes that are worlds apart in terms of emotion. Zimmer’s ability to create polarity with one piece of music clearly displays his strategic ability to place the music effectively. For example, one piece of music is used in a scene where two people kiss as well as just before a battle scene. In the former, the effect is one of tenderness and romance, whilst in the latter tension and violence is alluded to. A further example of this is how the use of music conveys the humble theme of the movie (the personal life of the character) while at the same time can be turned into thousands of different emotions. (hanszimmer. com, no date, a) Additionally, the tone of the music clearly changes as the film moves around geographically in order to represent the location. For example, the battle scene set in Germania consists of sustained, powerful strings and other skewed instruments which create a frantic and tense scene as well as authentically representing the location. Furthermore, for the scenes set in Morocco the sound is generally more tribal, dirty and gritty giving the sound in the movie a bigger range and representing the change in locations effectively (hans-zimmer. com, no date, a). The composition throughout the entire movie is mainly orchestral and this has the effect of transporting the viewer to the appropriate period of time in history that the film represents. All of this amalgamates to an all-round epic and large scale experience which is at the heart of the Gladiator’s subject matter. Another interesting aspect of Hans Zimmer’s work is to see how he portrayed one of the most iconic villains in modern day films in the Batman movie ‘The Dark Knight’ (2008). From the outset it seems that rather than create a happy, indulgent score, Zimmer wanted to create something hateful and provocative, something that the viewer could invest in. The Joker is the focal point of the film and represents a change from its predecessor, ‘Batman Begins’ (2005). In order to convey the significance of the character the sound that accompanies him on screen displays the anarchy, mayhem and insanity inherent to the Joker’s eccentric personality. youtube. com, no date). In an interview on the making of the film, Zimmer describes his attempts at depicting the tone of the character through the use of razor blades on barbed wire and incessant tapping on tables and floors, but he eventually came to the extremely successful technique of playing two notes on a cello at the same time, which juxtapose beautifully. This gives the effect of a taught string that gets tighter and tighter but never breaks, paralleling the Jokers spiralling descent into madness. Also, the note of the cello slowly but consistently rises in order to draw the viewer in as the character also does on screen. This extraordinary quiet, high-pitched sound which creates rising tension appears to have a 6 – Word Count: 3459 Student no. 15735 slightly anxious and uneasy quality which syncs perfectly with the character and the viewer’s perception of him. To accompany the sound of the cello, and add to the ever-growing tension two heavily distorted guitars, almost unrecognisable as the original instrument, are played with pieces of metal, with the result of creating a completely anarchistic atmosphere. These effects are heavily processed with the use of distortion to create a more surreal experience, detached from reality. These techniques fuse together to form a rich and complex tapestry of emotion, the audial and the visual aspects are combined in a way that portrays harmony as well as contrast. (youtube. com, no date). The final movie that will be discussed in depth is ‘Inception’ (2010). In the New York Times Zimmer describes his own understanding of the films subject as being about time and its slowing down, and speeding up. The Edith Piaf track ‘Je ne regrette rien’ is used as part of the film to signify a kick to another reality. However, Zimmer has taken its use to a deeper level â€Å"all the music in the score is subdivisions and multiplications of the Edith Piaf track† (Zimmer cited by Itzkoff, 2010) representing his perception of the film as being based around time and its manipulation. In the same way Zimmer manipulates the Piaf track by using a single beat and slowing it down dramatically in order to create the trademark foghorn sound that the movie is well known for (Itzkoff, 2010). The momentum of the film is defined by the structure of the score that accompanies it. The intensity of the film gradually snowballs, becoming more and more surreal and penetrating. At the same time the music increases in intensity and level of depth as the film explores the different levels of the human mind. In an interview with Hans Zimmer (hans-zimmer. com, no date) he describes making electronic sounds from scratch on the custom moog rack in his studio, as well as using software synths such as U-he Zebra. In order to create the sounds he wanted he would play the synthetic sounds to his bespoke orchestra which consists of; six bass trombones, six tenor trombones, four tubas and six French horns in order for them to imitate the sounds. Combinations of the two create a euphoric and emotive atmosphere where deep and unsettling synthetic and orchestral sounds accompany and synchronise with a powerful and grand visual experience. Whilst Zimmer has admitted ‘The Dark Knight’ was heavy in its use of electronic sounds in ‘Inception’ this is pushed even further. In order to gain a further insight into what Hans Zimmer is influenced by, it is important to consider the setting in which he creates his momentous scores. His home studio in Santa Monica, USA is extremely gothic in its decor and can be perceived as having an overwhelmingly dark and eerie vibe – somewhat consistent with a large amount of his compositions. This can be seen in the pictures below. (Pictures sourced from www. stuckincustoms. com) In picture one, we see that muted decadence is incorporated with the feeling of comfort. It is hard to imagine that influence would not be drawn from these surroundings. – Word Count: 3459 Student no. 15735 The second picture, displays the core of the hardware at Zimmers disposal. Whilst it is hard to make out the various components, some are identifiable; his Quested monitors (5. 1 surround sound set up), his Doepfer LMK4+ midi-keyboard, and two analogue synthesisers which are mounted on the back wall – one of which is a custom Moog rack (as mentioned above) and a custom Roland rack, as well as two custom HP touch sensitive LCD screen monitors connected to his DAW (Steinberg Cubase as his main sequencer and Pro Tools for his final mix) (hans-zimmer. om, no date, b). The picture on the right shows a large amount of Pro Tools systems and a patch bay as well as various other hardware devices. He also has a custom built Bosendorfer grand piano. It is also worth mentioning the software used by Zimmer which as well as the DAW’s described above include various VST’s such as; Omnisphere, U-he Zebra, Atmosphere and thousands and thousands of sample banks. (hanszimmer. com, no date, b) Hans Zimmer enjoys an astonishing career with some incredible a ccomplishments, despite the fact that he has had no formal training. His passion is maintained and can be seen in both the way he talks about the composition process as well as the finished product that is heard on screen. Perhaps, it can be said that in his work he is still battling his inner turmoil at the death of his father as a young boy; â€Å"[composing] was my way of calming the demons in me or at the same time sometimes letting them roar, letting them rip, letting the monster out and seeing that it wasn’t so scary being able to look it in the eye. † (CNN Worldbeat cited by IMDB, no date). It is argued here that in his work Zimmer forces his audience to confront the demons on screen whilst creating an opportunity for escapism which is what cinema represents. His productions are both seamless and effortless whilst at the same remaining extraordinarily powerful and commanding. As a relatively young composer and with some of the biggest and long-awaited Hollywood blockbusters ever to be produced in the pipeline, such as the sequel to ‘The Dark Knight’; ‘The Dark Knight Rises’, his success can only intensify with time.

Finance and Resource Management - Essay Example On the other hand new vehicle would be depreciated by $900 if the same technique were to be followed. The vehicle would be used, on an average 80 kilometers. The fuel efficiency is 8 kms per litre of petrol. Thus, there is a requirement to use 10 liters petrol. Each litre is costing about $2 and so petrol cost would be $20 per day and for 355 days, it would be $7100. The new vehicle has better fuel efficiency giving 10 kms per litre. It would thus require 8 litres per day and with the same cost of petrol, the yearly requirement would be $5680 (that is, 8 litre * $2 * 355 days). Cost of maintenance has gone up in the recent time. As the vehicle has been subject to severe wear and tear, the maintenance cost is estimated in the order of 20 percent of the car. That is, $1000 this year. But maintenance cost for the new car would be very low. It would not exceed 2 percent of its actual cost. This would be therefore $180 per year. Based on the information provided as above, the budget for operating the old vehicle has been mapped below. This has been juxtaposed against the possible cost that will be incurred for operating a new vehicle for similar purpose. Based on the above consideration, operating old vehicle is costlier than the new one. For instance, the annual cost of running the old patrol car is $8600, whereas that of new car would be $6760. There is a difference of $ 1840. In one of the company meeting, it was decided to have annual gathering under the pretext of a training program. The participants included middle level manager numbering about 25 from the United States. The department conducted basically a training program involving talk by about eight invited guests, who had to be given mementos. As these experts were drawn from best performers’ list working for our organization, it was decided that no honorarium would be paid. These participants were asked to stay in a hotel for 2 days. Hotel room tariff was $ 400 per day on twin sharing
