Alcohol Advertising Essay - 1140 Words

Alcohol Advertising Millions of Americans suffers from the effects of alcohol and drug abuse. It can shatter lives, brake families, and to rob people of their dreams for the future. Once alcoholism or drug addiction begins, an individuals problems not only dont go away, but their mental well being as well as physical ability continues to diminish from the immediate and long-term adverse effects from the drugs and alcohol abuse. Is it really true that advertising increases alcohol consumption, which increases alcohol abuse? No it is not. No solid evidence from either scientific research or practical experience that this theory of advertising is correct was identified. The United States Department of Health and Human Services in its†¦show more content†¦This is how young people view them. If one treats beverage alcohol as a dangerous substance to be avoided and not even advertised, he or she inadvertently can raise it up from the ordinary into the range of the powerful, the tantalizing, and the d esirable Big Deal. (Hanson, 1997). In so doing, we slip into the familiar, failed pattern of demonizing the substance of alcohol rather than discouraging irresponsible behavior. Alcohol addiction is a very serious and life threatening illness. Everything can get ruined in ones life. The life cycle of alcohol addiction begins with a problem, discomfort or some for of emotional or physical pain a person is experiencing and becomes difficult to deal with. At some point alcohol or drug enters the picture and provides a temporary, synthetic relief, and for a moment it seems to act as a solution to the problem. Alcohol addiction can be overcome and the individual can return to leading a happy, healthy, productive and responsible life once again. Often people drink during social occasions; it tends to loosen inhibitors. Unfortunately, the recklessness often is the result of excessive drinking and is a leading cause of serious injuries and accidental deaths. In addition, alcohol is the most common cause of preventable birth defects that include fatal alcohol syndrome. The effects of alcohol abuse can be short term and long term. Short- term effects of alcohol use include: alteredShow MoreRelatedAlcohol Marketing and Advertising25059 Words   |  101 PagesAlcohol Marketing and Advertising A Report to Congress September 2003 Federal Trade Commission, 2003 Timothy J.

Batteries and Their Importance Essay - 1061 Words

Batteries and Their Importance We use batteries everyday, we use them to start our cars and to listen to our Walkmans. I have a few questions: How do batteries work? What are the different kinds of batteries Batteries and Their Importance We use batteries everyday, we use them to start our cars and to listen to our Walkmans. I have a few questions: How do batteries work? What are the different kinds of batteries? Why do they die? Why do they lose energy when they are not used for a long time? Well I tried my best to find the best answers for these questions and a little more. Battery, also called an electric cell, is a device that converts chemical energy into electricity. All batteries contain an electrolyte, a†¦show more content†¦Another type of primary cell is the mercury cell. This cell uses zinc as the negative electrode, mercury as the positive electrode, and potassium hydroxide as the electrolyte. This cell gives about 1.3 volts of electricity, and is used in hearing aids and watches because the battery can be flattened. Primary cells maintain a positive charge on the positive terminal and a negative charge on the negative terminal, month after month. These charges attract another and sometimes manage to get to each other through the battery it self. When this happens the battery loses some energy. This is why batteries lose energy if not used. It is possible to slow this process down by refrigerating batteries. Dry Cell Battery The storage, or secondary cell, which can be recharged by reversing the chemical reaction, was invented in 1859 by the French physicist Gaston Plante. This invention was very crucial because it would revolutionize cars. Instead of crank starts the lead-acid battery was used. The lead-acid, which Plante invented is still the same basic design today. The battery consists of six cells connected in a series, and is used in automobiles. Its chief advantage is that it can deliver a strong current of electricity (starting an engine), however it runs down quickly. Each cell is made up of a number of positive and negative plates, separated by thin layers of wood, hard rubber, or plastic, called separators. All the positive plates are connectedShow MoreRelatedUsing Glucose Fuel Battery Of Artificial Pacemakers With Longer Battery Life1342 Words   |  6 PagesUsing glucose fuel battery in artificial pacemakers with longer battery life Abstract Battery life is an important performance of artificial pacemakers.

Computer Operating System Free Essays

An operating system (OS) is like a facilitator, providing an environment for application programs to run in. It provides an interface between computer hardware and the user of the application programs. Application programs are a stored set of instructions for responding to a specific request. We will write a custom essay sample on Computer Operating System or any similar topic only for you Order Now Hardware are the physical devices that make up the system such as the monitor, keyboard, printer, ect. The OS typically includes anywhere from tens to thousands of built-in subroutines called functions which applications can call to perform basic tasks such as displaying a string of text on the screen or inputting a character from the keyboard. The OS allows the user to interact with and obtain information from the hardware through a series of layers. The command layer is the only part of the OS that interacts with the user and sometimes is referred to as the shell. It is the user†s interface to the OS in that the user can request system services via a Job Control Language (JCL), which is the set of commands and their syntax requirements, or through a GUI (Graphical User Interface), the newest command language. The command interpreter decides which services must be executed to process the request and passes these to the service layer. The service layer accepts the commands and translates them into detailed instructions. There is one service call for each number of system requests provided by this layer. It handles functions in process control, file control, and device control. It makes requests to drivers for access to the kernel layer, which interacts directly with the hardware. Input must travel through these layers to reach the hardware and the results must travel back. First and foremost, an operating system must provide a mechanism for starting processes, which most of us know as programs. There are two main types of operating systems: single-tasking and multitasking. DOS is an example of a single-tasking operating system, which simply means that it can only run one program at a time. Windows95 (or newer editions, prior editions were a GUI interface to DOS) is the most widely used multitasking operating system on PC†s. Multitasking means that many programs can run at the same time. The processor (CPU), which selects and executes instructions, must divide its time to each active application to make it appear that all are running at once. These types of operating systems contain schedulers that divide the processor†s time among active processes. The schedulers are located in the kernel. Each process has one or several threads of execution. Every few milliseconds the scheduler takes control of the CPU from the thread it is currently executing, uses a complex time-allocation algorithm to decide which thread should execute next, and continues executing the thread at the point where it was last interrupted. The next fundamental duty of an operating system is to manage the memory – or storage of data – available to it and its applications. The goal in memory management is to give each application the memory it needs without infringing upon memory used by other applications. When a program is loaded and ran, the OS allocates a block of memory to hold the program†s code and data. If a program requires additional memory, it can call a function in the operating system to request more. DOS does not handle memory very well because it runs in real mode, where only 1MB of RAM (Random Access Memory) is addressable. The RAM is volatile memory that stores the running applications but the information is lost when the computer is turned off. Windows95 does a much better job of managing memory because it runs in protected mode, which allows it to use all memory, including extended memory. And even when that much memory isn†t enough, it can make more available by creating virtual memory from free space (space that has nothing stored in it) on a hard disk (non-removable secondary storage hardware device). Virtual Memory is a memory management technique that only loads active portions of a program into main memory. Windows95 also takes steps to prevent an application from accessing memory that it does not own. In DOS, and application can write to someone else†s memory, including the operating system†s, which can crash the entire system. Windows95 runs applications in private address spaces that are logically isolated from each other and identify the start of the file. One of an operating system†s most important components is its file system – the part responsible for managing files stored on hard disks and other mass-storage devices. An operating system provides high-level functions that applications can call to control file I/O, which covers the opening, closing, creating, deleting, and renaming of files. To read a chunk of data from a file, the application calls an operating system function and passes the operating system the file handle (which uniquely identifies an open file), the address in memory where the data should be copied, and the number of bytes to copy. The OS has to identify each sector on the disk that holds a portion of the requested file and program the drive controller to retrieve the information, sector by sector. It has to do this efficiently so that the information is retrieved quickly. The OS finds the right locations on the disk because it keeps a map that contains the name of each file and a record of where it is stored. DOS and Windows95 use a file allocation table as a map to find the locations. Another role that operating systems play in making a computer work is controlling device I/O. A device is a piece of hardware such as a video adapter, keyboard, or mouse. To talk to a device, a program must speak the device†s language, which usually consists of streams of 1†³s and 0†³s. There are thousands of different devices and â€Å"languages†, so the OS helps out by serving as an interpreter. It talks to the devices through device drivers, which are interface programs specially designed for each individual I/O device. Most operating systems like Windows95 come with dozens of different drivers for each I/O device. DOS also uses drivers, but they are often so primitive that the applications perform device I/O by relying on low-level routines encoded in ROM (Read Only Memory – allows the data to be read but not written) in the computer†s BIOS (Basic Input/Output System) or by talking directly to the hardware.

Introduction to Operating System:- Computer is a somewhat complex machine. The world has become accustomed to so many choices. We will write a custom essay sample on Computer Operating System or any similar topic only for you Order Now One of the major choices in the modern era is the â€Å"Operating System (OS)†. Operating systems are the central software component to any computer. The main brands of operating system are; Windows Mac OS, Sun Solaris, UNIX, DOS and Linux. Each brand has its own take on what makes up an operating system. Windows is the most commonly used operating system around the world. The most common advantage about Windows is its simplicity. It is now very easy for an inexperienced person to grasp the concept and use the computer with this operating system on it. Windows newest version is Vista and windows7. Vista has made computing a lot safer. Unfortunately, the simplicity which was there with previous versions has gone out of other version of windows. With its focus turning to security, lots of the simple things have been changed to turn into harder tasks. Windows was the first operating system to make the use of the computer simple. This has allowed a computer revolution as more and more of the world becomes computerized using windows as its operating system. The main bad point about Microsoft Vista is the price tag. For what it is, it is not worth the price tag, but people want simplicity, so they pay that little bit extra, so they get to use what they work with on a day to day basis in work places all around the world. Thus, the operating system (OS) is a computer program (system software) that acts as an intermediate between user and computer hardware. This is the first software that we see when we turn on the computer and the last software when we turn off the computer. It provides higher level abstraction. In conclusion, it is a master supervisory program which provides friendly interface for the user to interact with the computer and its peripherals and different application software as well as an environment for programs or applications to execute. 2. Functions:- ? Scheduling: – One of the functions of operating system is to allow multiple programs to execute in single processor system. There is fast switching of processor time for each job waiting for processor time. ? Interrupt handling: – It determines the causes of the interruption and passes control to another module of the program which was interrupted. Memory management: – It stores programs which are needed the most. The management of working area to execute the program is memory management. Memory management is all about transfer between the main and backing storage. ? Virtual memory management: – It is a technique for making computer appear to have more memory than it actually has. By this proces s we can load small portions of hard disk and process it when needed and swapping them out when another process is to be carried out. ? File Management: – It works on the basis of FAT. It allocates space on the storage media to hold each file which is stored and de-allocates space when needed. It maps logical file address to physical disk address. ? Resource allocation: – In large computer systems which are capable of running several programs at once, operating system is responsible for allocating processing time, memory and resources. All the jobs are performed in order as they are to be performed and as they are submitted, then operating system schedules them in order to make the best possible use of the resources.

Its current best-selling products are the Microsoft Windows operating system and the Microsoft Office suite of productivity software. Starting in 1980, Microsoft formed an important partnership with IBM that allowed them to bundle Microsoft’s operating system with computers that they sold, paying Microsoft a royalty for every sale. In 1985, IBM requested that Microsoft write a new operating system for their computers called OS/2; Microsoft wrote the operating system, but also continued to sell their own alternative, which proved to be in direct competition with OS/2. Microsoft Windows eventually overshadowed OS/2 in terms of sales. When Microsoft launched several versions of Microsoft Windows in the 1990s, they had captured over 90% market share of the world’s personal computers.

You read "Computer Operating System" in category "Papers" It was the most commonly used member of the DOS family of operating system and was the main operating system for computer during 1980s. Several variants of DOS are available including Microsoft version dos (MS-DOS), IBM’sversion (PC-DOS), and several others. It is a single user and single-processor operating system that uses a command line interface known as DOS prompt. There are several levels to DOS. At the lowest level are the Bios (Basic Input/output system) which are responsible for managing devices like Keyboards and disk drives . The next level provides a set of higher level services implemented using the low level BIOS services; one can refer to disk drive1as â€Å"drive A:†and instead of referring to specific sectors or tracks we can refer to files by name (example LETTER. TXT). This layer of the system is implemented by another file which is loaded when the system starts up (the file is called MSDOS. SYS on MS-DOS systems, and IBMDOS. com on PC-DOS systems). The third layer is the command interpreter (or shell), which is what most people think it as DOS. This is contained in another file called COMMAND. COM, which is just an ordinary program that is started automatically. The shell job is to display a command prompt on the screen as to type commands. Applications are executed at the top of the shell. [pic] Fig: Logo of MS-DOS History:- MS-DOS (short for disk operating system) is an operating system commercialized by Microsoft. It was the most commonly used member of the DOS family of operating system and was the main operating system and was the main operating system for computer during 1980s. It was based on the Intel 8086 family of processors, particularly by operating systems offering a graphical user interface. It was known before a QDOS (Quick dirty operating system) and 86DOS. MS dos was originally released in 1981 and had eight major versions released before Microsoft stopped development in2000. It was the key product in Microsoft’s growth from a programming languages company to a diverse software development firm, providing the company with essential revenue and marketing resources . It is also used in GUI operating system such as windows as basic operating system.

Linux:- [pic] Fig: Logo of Linux Introduction:- The term Linux is actually referred to mean a kernel of UNIX like operating system developed by a finish soft ware architect Linus torvald. The name Linux is derived from linus and unix. The Linux kernel is an operating system kernel used by the Linux family of Unix-like operating systems. It is one of the most prominent examples of free and open source software. Torvalds originally used Minix on his computer, a simplified kernel written by Andrew Tanenbaum for teaching operating system design. In April 1991, Linus Torvalds, a 21-year-old student at the Helsinki, Finland started working on some simple ideas for an operating system. He started with a task switcher in Intel 80386 assembly language and a terminal driver. , Linus However, Tanenbaum did not support extensions to his operating system, leading Torvalds to write a replacement for Minix. Linux started out as a terminal emulator written in IA-32 assembler and C which was compiled into binary form and booted from a floppy disk so that it would run outside of any operating system. The terminal emulator was running two threads: one for sending and one for receiving characters from the serial port. When Linus needed to write and read files to disk, this task-switching terminal emulator was extended with an entire file system handler, and after that gradually evolved into an entire operating system targeted at POSIX-compliance. Linus implemented enough POSIX system calls to make Linux run the Bash shell and after this bootstrapping procedure the development rapidly speed up. Although a running Minix system was originally necessary in order to configure, compile, install and run Linux, the Linux system quickly surpassed Minix in functionality and was soon able to boot on its own and compile its own source code. Linux is written in the version of the C programming language supported by GCC (which has introduced a number of extensions and changes to standard C), together with a number of short sections of code written in the assembly language.

The Macintosh is often credited with popularizing the graphical user interface. The Mac OS has been pre-installed on almost every Macintosh computer ever sold. The operating system is also sold separately at Apple retail stores, and online. The original Mac OS was partially based on the Lisa OS, previously released by Apple for the Lisa computer in 1983. It was the first Graphical User Interface (GUI) based Operating system. It was more user friendly and had a high quality graphics. It is more popular in graphical designing, animations and audio and video processing. Apple marketed its operating system software as â€Å"Mac OS†, in the beginning of 1997. The computer manufactured by Apple Macintosh Inc. needs operating system manufactured by itself otherwise it does not work. Apple was very strong in advertising their newfound machine. After it was created, the company bought all 39 pages of advertisement space in the Newsweek magazine, 1984 November/December edition. Apple was so successful in its marketing for the Macintosh, that it quickly outshone its more sophisticated predecessor, the Lisa, in sales – so much so that Apple quickly developed a product called MacWorks which allowed the Lisa to emulate Macintosh system software through System 3, by which time it had been discontinued as the re-branded Macintosh XL. Many of Lisa’s operating system advances would not appear in the operating system until System 7.

UNIX:- [pic] Fig: Logo of UNIX OS Introduction:- It was developed by a team or group of programmers at Bell Lab (ATT). It was developed in the early 1970s. It is open source and free of cost. UNIX (officially trademarked as UNIX, sometimes also written as Unix with small caps) is a computer operating system originally developed in 1969 by a group of ATT employees at BELL Labs. Today the term UNIX is used to describe any operating system that conforms to Unix standards, meaning the core operating system operates the same as the original Unix operating system. Today’s UNIX systems are split into various branches, developed over time by AT as well as various commercial vendors and non-profit organizations. As of 2007, the owner of the trademark is The Open Group. During the late 1970s and early 1980s, the influence of UNIX in academic circles led to large-scale adoption of UNIX by commercial startups. The term â€Å"traditional Unix† may be used to describe a UNIX or an operating system that has the characteristics of either Version 7 Unix or UNIX System V. As of 2007, the owner of the trademark is The Open Group, an industry standards consortium. Only systems fully compliant with and certified according to the Single UNIX Specification are qualified to use the trademark; others are called â€Å"UNIX system-like† or â€Å"UNIX-like†. During the late 1970s and early 1980s, the influence of Unix in academic ircles led to large-scale adoption of Unix (particularly of the BSD variant, originating from the University of California, Berkeley) by commercial startups, the most notable of which are Solaris, HP-UX and AIX. Today, in addition to certified UNIX systems such as those already mentioned, Unix-like operating systems such as Linux and BSD are commonly encountered.

The operating software is the one to make other software work. It provides a platform for users and other software to work. The operating system should be choosed on the basis of one’s need and how the user wants programs to work. We should also focus on the user friendliness of operating system. We should choose operating system on the basis of its cost to operate and its compatibility with other programs. The Microsoft windows are used in huge number as operating system rather than other operating systems due to its simplicity and easy access.

Transcendentalism Wrap Up Project free essay sample

Some of the songs on the CD aren’t exactly clear on their transcendentalist properties, so I decided to just be Thoreau (yes that is a pun) and go through and define the songs’ transcendentalist properties. Tracks 1. )The Dive by Eyedea Abilities- Aside from being an awesome and thought provoking song, this track opens up the ideas of Emerson’s Self- Reliance for me pretty well. The song talks about how someone goes out to look for the meaning of life and existence, rather than seeking it from within. The person in the song goes insane over time, and gets further and further away from the truth the harder they look for it. This personifies the idea that seeking outside of one’s self will not lead to true knowledge and wisdom, a totally Emerson idea. 2. Come As You Are by Nirvana- This happens to be not only one of my favorite songs of all time, but also a great representation of Self-Reliance’s ideas of being yourself and not trying to conform. This is contradicted a little bit when Kurt Cobain says, â€Å"come as you are, as you were, as I want you to be†¦Ã¢â‚¬  rather than allowing the person addressed to come as they themselves want to be, but otherwise I think that the song supports Emerson’s ideals pretty well. 3. Gone by Jack Johnson- This song is a bit mellower than Nirvana, but it still projects a similar idea. JJ sings about how worldly possessions are just material things, and don’t define a person, and thus are unimportant. He says, â€Å"gone be the birds if they don’t wanna sing, gone people all awkward with their things†¦Ã¢â‚¬  which I like to interpret as a metaphor for ignoring those who don’t conform, either by not singing, or by being â€Å"awkward with their things†. So maybe Jack Johnson isn’t so transcendental, but hey, parts of it work, and he might just have meant that he wants everything to be the way he wants it to be. Birds singing, no awkward, materially obsessed people. 4. )Forest Whitaker by Brother Ali- I really like this song, because it makes me feel good about myself, which is always nice. Aside from being a nice fun song, Bro Ali raps about how he accepts himself, and refuses to change himself based off of what others think he should look or act like. This falls directly into what I’m calling the Emerson category, and more specifically, the Self-Reliance category. I’m just saying, perfect example. 5. ) Express Yourself by N. W. A. Possibly the only song that’s relatively clean by N.  W. A. , this song seems to have been influenced by a couple of transcendentalists. It transitions well from the ideas of Emerson to those of Thoreau, saying that you should, â€Å"Express yourself†. (duh) Also, the song talks about how you should be out on the street protesting, and, â€Å"Expressing yourself with full capabilities, and living in correctional facilities†. You can feel free to shower compliments on me for how perfect some of these songs are. I don’t mind. 6. )Not Afraid by Eminem- The chorus is fairly self-explanatory. â€Å"I’m not afraid to take a stand, everybody come take my hand, we’ll walk this road together†¦Ã¢â‚¬  Eminem clearly is not afraid to stand up to society and, assuming that the content of his other work is consistent with his beliefs, he doesn’t mind taking a stand against the government either. I hesitate to use another Thoreau-thorough pun, so I will just point out that Eminem seems to support Thoreau’s transcendentalist ideas of civil disobedience. 7. )Outta My System by My Morning Jacket- I feel like this is a Ramones type song if the Ramones were more into hallucinogens and flowers, and less into heavy drums and guitar solos. I could actually probably throw I Wanna Be Sedated into the lineup and rationalize it. Anyhow, this song talks about not listening to the â€Å"man† or, more specifically, â€Å"society† and trying to â€Å"get it out of my system†. Not exactly a transcendentalist idea, but Jim James is quite obviously acting outside of the law, â€Å"smoking drugs†, which Thoreau, at least, seems to love. Not smoking drugs†¦ acting outside of the law. He also steals cars apparently, which isn’t really a transcendentalist idea either. The point I’d like to focus on, however, is that Jim James is acting out against the rules and expectations set for him by others. So good for him, smoking drugs and committing grand theft auto. 8. )Prayer of the Refugee by Rise Against- Rise Against does a bunch of revolution-type songs, and I knew I would pick one of them for this project. I decided on Prayer of the Refugee because it talks about how, â€Å"the angry and the desperate, the hungry and the cold†, rise up against what I can only assume is an oppressor. The chorus is super transcendental, saying, â€Å"don’t hold me up now, I can stand my own ground, I don’t need your help now, you will let me down†. I’m convinced that someone paid attention to the class discussion on transcendentalism back in high school. This band could be hanging out with Emerson and Thoreau if the two weren’t so dead. So, in conclusion, I did an awesome job and I think that we should have more projects where we can utilize music and/or art. Not that I don’t LOVE reading Hawthorne and writing synthesis essays, but it’s nice to mix it up. By the way, Fergalicious is a BONUS TRACK, in which I can’t find any transcendental ideas, but I hope you enjoy it simply for enjoyment’s sake. Happy Thanksgiving!

Rembrandt Essays - Joseph, Book Of Genesis, Erotic Art,

Rembrandt The story of Joseph and Potiphar's wife is told in the first book of the Bible, Genesis, chapter 39. Joseph was sold into slavery by his brothers and bought by Potiphar, a high ranking official in the Pharaoh's service. "The Lord was with Joseph," and gave him success in everything he did. This pleased Potiphar and before long Joseph was given the highest position in the household, and left in charge when Potiphar was away. Now Potiphar's wife found Joseph to be very good looking and had approached him several times saying "come to bed with me;" and Joseph being a man of God would not sin against his master or the Lord, so he refused her. One day when all the servants were gone, Joseph entered the house and Potiphar's wife approached him and while holding on to his cloak said "come to bed with me". Joseph refused and left the house leaving his cloak behind. Potiphar' Wife screamed for help saying that Joseph had attacked and tried to sleep with her. When her husband came home she told him the same false story. Potiphar was so angry at Joseph he had him locked up in Pharaoh's prison. "But while Joseph was in the prison, the Lord was with him." This is the subject matter for which Rembrandt choose to do his representational painting by. The content of the painting all reveals Rembrandt's interpretation of the story This is the account from the Bible of the accusation of Joseph by Potiphar's Wife. Rembrandt Van Ryn chose this particular story as the subject of his narrative painting completed in 1655, under the title of "Joseph Accused By Potiphar's Wife". Before researching this painting, I noted my fist perception of Rembrandt work of art. I realized through that as a result of my later research, my first perception did not change, but instead were enriched and enlarged by a newfound understanding of the man and his art. I largely concentrated on my first and later perceptions in the design elements and principles of lighting or value, infinite space, color, and focal point. After conducting research, my first perceptions about the value, or relative degree of lightness or darkness, in the painting did not change, but instead I learned that Rembrandt's use of light and dark was both purposeful and a technique well- known to the artists of his time. When I first observed this painting, I thought how dark everything seemed. The only exceptions to the darkness are the bed and Potiphar's wife, both of which are flooded in light almost as if a spotlight were thrown on her and the bed. Some light shines on Joseph's face and from behind him like a halo around his body, but this light is very dim. Potiphar in great contrast to his wife is almost in complete darkness. I first felt there should be more light from perhaps candles to cast the entire room in partial light. But after research I found that "Rembrandt liked strong contrasts of light and dark and used them in his paintings all his life, letting darkness hide unnecessary details while using light to bring figures and objects out from the shadows. The high contrast of light against dark changed an ordinary scene into a dramatic one ... the Italian word for this use of light and dark [is] chiaroscuro " (Muhlberger 9). Rembrandt must have believed that too much detail in the room would have obscured the primary players of this scene. He uses light to brightly illuminate the most important person in this painting, Potiphar's wife. In descending order of importance, Rembrandt places a glow around Joseph and casts Potiphar in a almost total darkness. I now am able to see how the contrast of light and dark demonstrates drastically this crucial turning point in Joseph's life. The fact that an Italian word exists for Rembrandt's lighting technique only proves the technique's establishment in the art world he lived and worked in. As a result of research, my fist perceptions about the presence of infinite space in the painting did not change, but instead I gained an understanding of why Rembrandt employed this particular technique in his painting. I first noticed before conducting any research on Rembrandt or this painting how the walls appear to go on indefinitely; there are no boundaries to the room. In addition the artist chose not to add and details to the walls or floor. I believe that the design element of infinite space, endless space as found

Population inflation Essay Example

Population inflation Essay Example Population inflation Essay Population inflation Essay Population inflation has become a constant problem and a developing conflict for all the nations in the world especially those with such little total land gross area. Urbanization and Population growth seems to coincide because both of it has become growing concerns of the world today. Though Urbanization has the more positive side of it, there are still some who oppose this ideology. Regarding population growth, it has become one aspect of the global community that indicates such a threatening reality. The people are multiplying by the minute but the resources that keep the people alive has become more scarce through the years. The scarcity of resources to satisfy population has become blatantly damaging. The growth rate around the world is increasing every year and as seen in the worlds most populous countries such as China, India, USA, the population has been inflating due to birth and fertility rate. Answering to the problems caused by overpopulation, urbanization solutions has become one arguably reliable remedy. There are four examples of cases where a positive output was produced and was recognized in the 1996 Dubai Awards. These are the Institutionalizing of Community-Based Development in Abidjan, another was the action by the Self-Employed Womens Association (SEWA) Bank, another was the City Management in Tilburg ranging from the past, present and the future, these are samples of overcoming the challenges of population and urbanization. Urbanization can produce both negative and positive effects on communities, depending on how the leaders of these communities take advantage of it. There are possible environmental problems due to urbanization but there are also environmental benefits due to urbanization. Its like a give and take relationship for population and urbanization, the importance of how the population should be treated must coincide positively with how urbanization should be handled properly to reap benefits for the population.

The Great Awakening Essay Example | Topics and Well Written Essays - 1500 words

The Great Awakening - Essay Example The Puritans gained ascendency as a reaction to the perceived corruption and worldliness of the Church of England, while Catholics were a small minority. In 1670, Charles 11, followed by James 11, reestablished Catholic control. The Glorious Revolution of 1688 saw William and Mary put an end to Catholicism, repress other minority religious groups and unequivocally reinstate the Church of England as the dominant religion. The Anglican clergy shunned doctrinal extremes and adopted a moderate path. Religious belief was confined to mere nominal participation in church services. At the beginning of the eighteenth century, Charles and John Wesley, along with others like George Whitefield, â€Å"reacted against the coldness of religion and the deistic rationalism which prevailed† and revived the personal significance of the gospels (Great-Awakening.com, n.d.). These were the seeds of the Great Awakening. ... The political scene in England, described above, engendered an atmosphere of uncertainty in the colonies. These economic and political changes diverted the populace from religious concerns. Orthodox Calvinism was also challenged by the rationalism of the Enlightenment, which rejected the Puritan emphasis on the â€Å"inherent depravity† of human nature. The Enlightenment’s emphasis on logic and reason led to the study of theology being superseded by the introduction of math, science, law, and medicine into the college curriculums. Economic success and rational thought took precedence over religion and led to a laxity of morals. This weakening of religious commitment was further exacerbated by compromise within the Congregational Church. In order to stop the sharp decline in church congregations, the Congregational Churches of Connecticut and Massachusetts adopted the Halfway Covenant in 1662, by which churches baptized the second generation of Puritans as infants, with the assumption that they would be converted later in life. Again, the churches ignored the failure of this generation to adhere to this conversion stricture. The children of unregenerate Puritans were baptized but forbidden communion. By thus isolating the third generation of Puritans from the traditional means of receiving God's grace, this Covenant furthered the degeneration of the church. In 1690, the â€Å"halfway members† of the church were allowed to receive Communion. In effect, â€Å"the second and third generations of Puritans failed to demonstrate the same devotion and discipline that the original Puritans had practiced† (Valkenburg, 2011).  In 1708, the Saybrook Platform, or fifteen â€Å"Articles for the Administration of Church Discipline,† attempted to

Compassion of Strangers Essay Example | Topics and Well Written Essays - 750 words

Compassion of Strangers - Essay Example Nying Je can be paraphrased as love and respect--compassion in its purest form is ‘unconditional and universal in scope’. The Dalai Lama’s compassion is described differently and in a much wider context, encompassing a notion that some of us might describe as unconditional love: "At the heart of Buddhist philosophy is the notion of compassion for others†¦[it] is not the usual love one has for friends or family. The love[†¦]is the kind one can have even for another who has done one harm. Developing a kind heart does not always involve any †¦ sentimental religiosity [†¦] It is not just for people who believe in religions; it is for everyone who considers himself or herself to be a member of the human family, and thus sees things in accordingly large terms.† In essence, this love is for all sentient beings as an extension of oneself. The writer continues, noting that "the rationale for universal compassion is based on the same principle of spiritual democracy[†¦]the true acceptance of the principle of democracy requires that we think and act in terms of the common goo d.† Compassion, in this essay, takes on a significance slightly different than that commonly accepted by western civilization. We feel compassion as a type of absent sympathy, as something that touches us, sometimes profoundly, on the part of another; however, compassion in our society is largely a secondary emotion. According to His Holiness, however, true compassion is a selflessness that lends itself everywhere and to everything; in the moment that a compassionate human being witnesses the suffering of another, that human being is immediately moved and internally obligated to do whatever possible to alleviate said suffering. Within compassion is mentioned the concept of universal responsibility, as both an offshoot and a critical component of this emotion: "[†¦]

Barista Structure And Culture

Barista Structure And Culture This report is about the performance of the Barista Cafe. It is owned by Lavazza, Italys largest coffee company which has 46.5% shares in the Italian market and operates in more than 80 countries in different sectors. It is very essential for the company to put emphasis on organizational aspects such as the Structure, Culture and the Design. This report mainly analyzes the organizational structure and culture of the company and how they are changing according to the global competition market. Every structural design they have followed evidently shows the history and the perfection of the company.   The Barista Cafe chain is also known as Barista Lavazza. The name Lavazza, being synonymous with all things Italian culture creativity, art, passion for espresso, evolved into an international powerhouse of Italy. The first ever Cafe Barista was established in 1999. The following report starts off with detailing the structure and culture of Cafe Barista and further focuses mainly on the ir Indian counterpart known as Barista Lavazza. The company was promoted with initial amount of Rs.20 Crores by Java Coffee Company Ltd., owned by the Turner Morrison group of Lacoste fame. Barista Lavazza (coffee) chain of Espresso bars has franchisee outlets in 22 cities all over India, which deliver a true Italian coffee experience to their customers. Their main aim is to provide a true ambiance for people to enjoy their cup of coffee, enhanced by their very own Latte art. Cafà © Barista targets young adult people as their clientele, who come to the cafe to get exposed to the global lifestyle and taste the bonafide flavours of coffee. The Structure: The structure of the Barista Lavazza is relatively a Mechanistic structure, since the majority of the personals who are working in the organization are involved in the production and sale departments, while the decision making powers are in couple of hands in management. Each person is individually specialised and is aware of their responsibilities (Jones 2006, P177-198).  Production, Sales and Marketing and lastly the General/Administrative group are the three functional groups that comprise the structure of Cafe Barista  Production involve the Customer Service Specialists, who will be manning the Drive-thrus and Mobile Cafes and blending the beverages for the customers. Sales and Marketing handles the promotion and scheduling of the Mobile Cafes, as well as the promotion of the Drive-thrus and the Community Contribution program. General and Administrative manage the facilities, equipment, inventory, payroll, and other basic, operational processes.   The Culture: The culture of Cafe Barista is very elaborative as the Organizational Culture is sets of shared values and norms that guide organizational members interactions with each other and with people outside the organization (Jones, 2006, P213). They are based on the terminal values of the customers as it is said, Terminal values is a desired end state or outcome that people seek to achieve. (Jones 2006, P214). It explains their cultural diversification through three groups- Coffee Know -How, Art of Espresso and Innovation. These three are mostly prior to the Indian culture and shows how Lavazza gets a chain of Espresso Bars and Crà ¨me outlet to their customers to provide them a comfortable place to enjoy a cup of real coffee. For them the art of making coffee is all about the care, attention and skills and brewing the coffee perfectly. They follow a special espresso brewing process where they use 4Ms model in place: La Machine: The Machine La Miscela: The Blend La Macinatura : The Grinding La Manualità   : Your Touch They always try to ensure that their consistency and skills deliver the best to their customers and provide their 4 rich elements of good espresso; the flavour, the aroma, the crema and the texture. They provide training to their employees based on their geographical location, to ensure best service for the customers As it is said, Every cup of coffee they brew is recognized as a best flavour and aroma of every piece of coffee beans. They form the bases according to the cultural changes in the taste of the people and they provide infinite variations according to the taste which will suite the people. They offer five kinds of flavours to people with different services which are: Espresso Italiano: short, dark and handsome in the taste, this is not mix with milky, frothy drink Espresso Macchiato: this stand for the marked with a teaspoon of foamed milk or sometimes as dash of cold milk Cappuccino: the greatest flavour of Italy topped with steamed milk and foamed milk in a thick cup that contains flavour. Cafe Latte: drink originated in USA, which is served in mugs with shorts of espresso and milk. Cafe Mocha: a combination of intense espresso and freshly steamed milk and rich chocolate powder which is often known as Dessert of Cup. These all flavours are made for the people according to the changing environment and the tastes of the people. On the basis of these change, Barista have to come with some new innovation ideas by doing research. Their research was their backbone for their product and RD teams who spend identically 4 hours on each store in a month and observing the guest feedbacks. Their research helps them to identify their key global trends and how well they can refresh their product lines. Barista Cafe is a dimensional brand which always focuses on providing differentiating offers or services to their customers. They use the guest surveys and feedbacks to focus on their innovation of products and the services which will be very affectionate to them. At the Barista Lavazza they invent new food and beverage lines almost every year. These inventions are basically based on the global trends, customers feedback and the regular research they have done. They always try to continue their innovation among t he products that glee their customers. As their main target is their customers who are living in global lifestyles so, they always try to appreciate their innovation in the behalf of their customers with the warm environment. Their focus always is on innovation and continuously providing quality products. This was the reason why they try to make their every cup of drink pretty by using barista art. They use some elaborative designs which express the people feelings and affections. Their method of making coffee was mainly evolved in creating the coffee into an artistic quality which technique is known as Latte Art.  Lattes are the preferred drink to use for this because of its good foam to milk ratio.  This kind of art is consisting of pouring the steam milk into the small short of espresso which will create the design on the surface for the latte art. This art is very difficult to create due to the different demands in both espresso and milk. This way of art can beautifully hold the heart of the people which makes people to drink that coffee. Barista also use a theory which helps the company in RD and innovation. SWOT -Analysis is the most strategic management model which fits between the organization strength and weakness with the different opportunities and threats in their external environment.  As said by  Jones, SWOT- Analysis guides you to identify the positives and negatives inside and outside of your organization and analysis will provide perspective, and reveal connections and areas for action. The main objective of SWOT for Barista is to determine to which level the strategy of the company will be suitable to them to meet their challenges and changes which are occurring in their organizational environment. The SWOT -Analysis of the Barista is divided into the four factors of the companys Strength, Weaknesses, Opportunities and Threads which are as follow: Strength of the Barista Lavazza: their main strength is their product in the market. They are having very skilled, committed and professional team which provide high margins on beverages appliances which will cost them low setup money. Weaknesses: their weakness is that they reliance to one client initial and they have to spend alot on the stainless steel appliances. The management team of barista doesnt work for that long in India so they dont know that much about the people taste. The sales and marketing team is not place in the market for the promotion of their products and they have very less US and Italy taste experience. Opportunities:  they have opportunity to expand their product in the market by increasing the awareness of their specific coffee products in the market. They also have the opportunity of innovation within the existing market by the help of people feedback. Threads: the biggest thread for the company is the competitors like Starbucks and Cafe Coffee in India. There is also an adverse reaction on the soluble coffee in the stores. Another issue was the filtered coffee was firmly established in USA and they were not aware of the USA experience. Untitled.jpg Diagram: www. marketingteacher.com So, the SWOT- Analysis helps the organization of the Barista in identifying the issues they are facing, setting up the goals and creating their proper action plans. SWOT is a simple method of assessing the positive and negative factors that are forcing within and outside the organization; they can prepare themselves and act perfectly. This will help in supporting them in their vision, mission and objectives. Conclusion: Barista have been performing well consistently as it is essential for the company to maintain the strength of the brand and capitalize on the loyalty of the brand and the market shares. The overall strength of the Barista is about their service and their behaviour towards their customers, which was the advantage for the company especially in their services. Holding a futuristic vision, Barista as a company constantly tries to innovate itself and further enhance their brand image in order to expand its hold over the market. Barista has very strong image in the market, but they need to work on their structure so they can improve their company performance and their customers perceptions of being high-end quality coffee. Thats was the recommendation for barista is to keep on making changes and innovation. They should promote their product and work on their organizational objectives and aspects especially for coffee and other services they are providing. Another recommendation would be they should adapt innovation -friendly organization which inspire culture and empower their employees. They should use the todays business evolutionary method which helps in rapid economic or social changes by driving knowledge and innovation among the employees. At this level, the sales and marketing departments need to be more centralized and focused on their task. Barista is customer-oriented so, the people who are more close to the customers need to know them better and respond them rapidly with their changing requirements. If the organization is still using the Flat structure, they need to make their decisions quickly and they need to creative for employees and their customers. Lastly, as they have fewer layers of organization, so they need to be mobile and agile to the decisions which they are making this will help them to be more effective, competitive and profitable. As in todays global world, organization is all about how creative and dominant they are in the market. Thats why more companies prefer to have flat structure, as flat structural organization is enables great communication between the layers of the organization with better team spirit. Flat structural organization with benefit the management as lower cost will be paid to the managers than the workers and less bureaucracy will be involved in the organization.

Inca :: essays research papers

Inca Empire: What Could Have Been Watching the 2 videos on the Inca Empire was very enlightening. I learned much about the Inca customs, farming, community and religion. I wondered as I viewed the film, how different the country of Ecuador might be if the Incas had defeated the Spanish. A family divided decided that fate. Two Brothers In 1526, the ruler of the Incas, Huayna Capac, died. The custom of the time was to leave the empire to one son. Instead, Huayna divided the inca">Inca Empire between his two sons, Hu`ascar of Cuzco and Atahualpa of Quito. This was the first time in the history of the Incas that the empire was divided. A rivalry between the brothers soon began and worsened over time. The Inca of Cuzco with Hu`ascar as their ruler went to war against his brother Atahualpa and the Incas of Quito. After several years of fighting, Atahualpa finally defeated his brother and was thus became the sole ruler of the weakened and still divided Inca Empire. In 1532, Francisco Pizarro arrived with plans to conquer the Incas. A meeting was arranged between Pizarro and Atahualpa. Although, Atahualpa was prepared to negotiate with the Spaniards, Pizarro had other ideas. When the Inca arrived at the meeting place, the conquistadores captured Atahualpa and killed his guards. Pizarro held Atahualpa for ransom to collect gold, silver and other valuables from the Inca people. Instead of being released when the ransom was paid, the Inca ruler was tried for several crimes against the king and sentenced to death. His death brought the Inca Empire to an end. Conclusion What if the two brothers had not gone to war; what if Atahualpa and his guards defeated the Spaniards; or what if Pizarro had released the ruler as promised?

Football Coach

Football Coach As the sun rises to its highest peak of the day, the local high school team starts heading to the dry dirt filled football field. As the athletes make their way to the field the dust rises and the smell of the soil hits their nose. The athletes continuing their daily ritual, get into their usual formations and start their warm ups. The head coach, Shane Cox, walks around and initiates small talk with the players. Shane Cox inherited the head position at Fairfax High School in 1999. He turned around a football program that hasn’t won a single football game in two years; Shane Cox has won two Los Angeles Division II City Championships in the past decade. Serving for more than 13 years, Coach Cox has contributed a lot of his time and effort into this program at Fairfax High School. A high school coach has to work additional hours during the sports season. This can result in a work week over 40 hours. Working nights, holidays, evenings and weekends are common for high school coaches. A high school coach has to be prepared to work in bad weather and be willing to travel with the team to different locations for games. They also run the risk of injury due to being on the sidelines during sports games. Although Coach Cox’s accomplishments for coaching are impressive, his accomplishments off the field are impressive as well. A football coach’s job is to not only improve his player athletically, but as a person as well.

also can be thought of as betrayal and revenge. The Oresteia originally consisted of four plays-Agamemnon, The Libation Bearers, The Euminides and Proteus. Proteus did not survive, though the three tragedies form a unity in themselves as the only Greek trilogy we have. In this essay I will only focus on one of the three plays, called â€Å"The Libation Bearers†. The other play I will be looking at is â€Å"Medea†. Medea is the earliest tragedy of Euripides and in it we see a classic moral pattern. Aspects such as betrayal and revenge are explored in this play, such as also in The Libation Bearers, which can also be recognized in many modern plays today. It shows how strong feeling from one person to another can make you do things that are reactions of love and hate. The first play I will look at is The Libation Bearers, and how already from the start Tantalus of Lydia betrays himself by killing his own flesh and blood.

Uncertainty avoidance Essays

Uncertainty avoidance Essays Uncertainty avoidance Essay Uncertainty avoidance Essay Uncertainty avoidance 1 . uncertainty Avoidance, a societys tolerance for uncertainty and ambiguity. It reflects the extent to which members of a society attempt to cope with anxiety by minimizing uncertainty. The uncertainty avoidance dimension expresses the degree to which a person in society feels uncomfortable with a sense of uncertainty and ambiguity. The fundamental issue here is how a society deals with the fact that the future can never be known: should we try to control the future or Just let it happen? Countries exhibiting strong Uncertainty avoidance Index or IJAI, maintain rigid codes f belief and behavior and are intolerant of unorthodox behavior and ideas. Weak I-JAI societies maintain a more relaxed attitude in which practice counts more than principles. People in cultures with high uncertainty avoidance tend to be more emotional. They try to minimize the occurrence of unknown and unusual circumstances and to proceed with careful changes step by step by planning and by implementing rules, laws and regulations. In contrast, low uncertainty avoidance cultures accept and feel comfortable in unstructured situations or changeable nvironments and try to have as few rules as possible. People in these cultures tend to be more pragmatic, they are more tolerant of change. 2 There are many ways to detect if someone has a high amount of Uncertainty Avoidance. For example, the use of formality in interaction with others, dependence of formalized policies and procedures, apparent resistance of change are all characteristics of high uncertainty avoidance. Signs of High Uncertainty avoidance More physical and apparent ways to detect if someone has a high Uncertainty Avoidance is to check if they display the ollowing descriptions or attributes. Do they follow a strict structure with rules and expertise, do they have high security (avoiding the unfamiliar). Also you can check if they are hectic, stressful or even emotional. 3 ln contrast people can also exhibit characteristics of low Uncertainty Avoidance. Unlike high IJA, those with a low level use informality in interaction with others, they often rely on informal norms and behaviors in most matters. Also, they will show moderate resistance to change. Signs of low uncertainty avoidance To detect if someone has a low uncertainty avoidance eep a keen eye out for the following symptoms and hints. Such people often abide by only a few rules and live a life with little set structure, one that is loose and free; they will appear to be calm and collected. Also, they are interested most likely in entrepreneurship and business matters. 4 Those with High uncertainty avoidance are often to be characterized as more careful and considerate types of people. However, the low uncertainty avoidance personalities are tend to show the highest risky natures. The following characterizations were by the average perceived Uncertainty Avoidance based on the basic concepts of Uncertainty avoidance like risky behaviors and personality. Low Uncertainty Avoidance Countries Some of the lowest uncertainty avoidance countries are unsurprisingly USA, I-JK, India, China and Indonesia, perhaps in an obvious way if you understand the concept of Uncertainty avoidance. These countries often are large capitalist countries that invest heavily and produce a lot while exhibiting signs of high and risky behavior. High Uncertainty Belgium, Italy, Russia, Korea and Mexico. These countries are for the most part elatively calm and collected. The countries usually participate in safe behaviors and live life with a rigorous and set structure. 5 Uncertainty Avoidance is taught so managers can have an idea what sort of rules and practices are accepted and necessary in different cultures. For example cultures with high uncertainty avoidance usually do better with more laws and regulations and cultures with low uncertainty avoidance expect more space and more freedom. Managers study uncertainty avoidance to be better prepared to manage in an international setting. 6 ln the ame way managers can face situations where they have to deal with employees of different cultures businessmen are expected to do business across different cultures and uncertainty avoidance can give insight to whether a culture expects you to strictly adhere to rules and traditions or whether you are allowed more freedom and familiarity. 7 Similar to international business, international communications requires you to bridge the gap between many cultures and adhering to social norms is an important part of international relations. And uncertainty avoidance applies to ocial norms in different cultures. 8 Uncertainty avoidance is important in international negotiations because negotiations relies on reaching an understanding and that can be made difficult if the other party expects you to follow different norms or if the other party is not comfortable with certain situations. Uncertainty avoidance also applies in many fields other than international business and the cultures associated with high or low uncertainty avoidance are also associated with specific traits. 9 n politics, cultures with high uncertainty avoidance citizens tend to have ow interest in politics and citizen protests are repressed. This is because political unrest would bring about changes which the majority would not be comfortable with. There also tends to be many laws with laws being more specific as to avoid any uncertainty in the interpretation and to guide which behavior is acceptable. On the other side of the spectrum in cultures with lo w uncertainty avoidance citizens tend to be very interested in politics as it serves as a tool for change. Protests are accepted as another tool for change and laws are general. 0 ln education, cultures with high uncertainty avoidance, teachers as viewed as having all the answers and learning is structured. A lot of focus is emphasized on mathematics and science. In cultures with low uncertainty avoidance, teachers are not necessarily viewed as all knowing and the learning is open minded with less focus on facts. Uncertainty avoidance also affects the family life, cultures with uncertainty avoidance tend to have rigid gender roles and cultures with low uncertainty avoidance have more flexible and more varied gender roles.

Most importantly, the reflective practice encouraged them to evolve and become more flexible to accept environmental changes vis-Ã  -vis technology, cultural diversity, challenges of job etc. While some believe that leadership is inherent, I am of the view that leadership traits can be developed. The various traits like accountability and strong sense of responsible behavior, integrity, honesty, critical thinking, flexibility, communication skill etc. are hugely important factors that make leaders effective. These traits are also something that can be cultivated. I foresee leadership development as means of enhancing the skills of communication, relationship building, improving decision making skills through informed choices. These things can be learnt through simulated clinical cases which are critical and require quick decisions. Moreover, interacting with senior and their peer group helps them to learn new ways of handling issues and resolve conflicts. Most importantly, programs must encourage acceptance of negative qualities so that they can be changed. It should equip them to turn adverse circumstances into new opportunities for success. (words:

Political Science- Middle Eastern Politics Essay

Political Science- Middle Eastern Politics - Essay Example There are two main answers to this difficult question. The first is perhaps the best. If Iraq asks for U.S. combat troops beyond 2011, America should agree, creating several rapid reaction forces, not numbering more than 20,000 soldiers, to help with problems that may arise. The hard part of implementing this policy will be selling it to both the American and Iraqi public. The second option the U.S. could pursue is to create a staging ground for a rapid reaction force outside of Iraq, perhaps in Saudi Arabia, which could be used in cases of emergency. Both potential strategies will be briefly discussed below. Many American lives have been lost in Iraq, and a great deal of money has been spent. It is tempting, now that violence has been dramatically reduced, to wash our hands of the issue. But the possibility remains that Iraq could revert to a chaotic situation and that we must not allow this to happen. The American Defence Secretary Robert Gates recently signalled that the Obama adm inistration would be willing to continue keeping combat troops in Iraq after 2011 if asked by the Iraqi government. The military commander in Iraq, General Austin agreed there may be a need for this: Speaking to a group of reporters travelling with Gates, Austin gave the strong impression that he thinks Iraq needs a U.S. military presence beyond December, but he said he had not yet been asked to provide a recommendation to Washington. He said Iraq faced the possibility of a "more violent environment" next year, given the absence of U.S. military force and the failure to resolve key political problems, like the Kurd-Arab tensions in Kirkuk and elsewhere in the north (NPR). The willingness is there among policymakers, but the largest problem would be convincing the American public that this was necessary. Strategically, this is one of the more difficult parts of the plan. Americans are sick and tired of Iraq. They want nothing more to do with it. While Republicans would probably side with Obama, it will be politically difficult for him to convince anti-war Democrats to permit American combat troops to stay in Iraq. Obama has already alienated left-wing Democrats with a number of his policies; facing reelection 2012, he might be loath to further enrage them, potentially inviting a primary challenge from the left. While the politics of this choice make it strategically difficult, it may be the only good option. Another strategy would involve refusing combat troops in Iraq, and creating a rapid reaction force nearby, in another country. There are problems with this idea, however. America is already committed to having a major diplomatic presence in Iraq after 2011. According to a recent Senate report: â€Å"The diplomatic mission that remains will be an initiative of unprecedented size and complexity, currently projected to consist of some 17,000 individuals on 15 different sites, including 3 air hubs, 3 police training centers, 2 consulates, 2 embassy branch offi ces, and 5 Office of Security Cooperation sites† (Senate Report, 2). Without a security presence, it will be very difficult to sustain this kind of operation. It may be in America's own interest, as much as the Iraqi's, to have a combat force in Iraq. American diplomatic operations will certainly attract fire in the years ahead, and it will be hard to trust the Iraqi army to properly provide security. Having a

Writer's choice - Essay Example This is because material misrepresentation of the facts of a product has a potential effect of making the customers to make decisions to purchase the product, something that would not have happened had the facts been set right. Misrepresentation of information to customers is both an ethical issue as well as a tort that can attract civil liability (CCAB, 2011). The ethical issue arises as the company’s president is only driven by greed desires to keep up with the external competition that the company faces. That is why he is keen on deliberating changing the estimated life of the company’s principal product, non-biodegradable plastic cartons, from 8 years to 12 years. He wants to do this to improve the profitability of the company while not putting the needs of the customers in mind. A potential ethical situation that can happen when dealing with bad debts is when the unethical accountants modify the financial registers of a company and scheme the numbers so as to generate a fabricated picture that the company is making profits (CCAB, 2011). This can arise if the accountant in custody of the company’s financial statements and balance sheets is under unwarranted pressure and tension from the management who want to record a success of the company. This pressure makes the accountants to provide deceitful reports of the proceeds, possessions and liabilities of the company. This type of a fraud is responsible for short-term remunerations for the company’s but it can also lead to the ruin of the company once it is discovered by the relevant authorities (CCAB,

Geometry in Everyday Life Essay Example for Free

Geometry in Everyday Life Essay A solar water heater is the most competitive alternative to conventional water heating methods such as electric geysers and fuel-fed boilers. It makes an attractive and sustainable option, with its global distribution, pollution free nature, virtually inexhaustible supply and near-zero operational cost. Solar water heaters run on a free fuel (i. e. sunshine), thus saving on energy costs that help recover its initial cost in just 2-4 years. Hot water throughout the year: the system works all year round, though youll need to heat the water further with a boiler or immersion heater during the winter months. Cut your bills: sunlight is free, so once youve paid for the initial installation your hot water costs will be reduced. Cut your carbon footprint: solar hot water is a green, renewable heating system and can reduce your carbon dioxide emissions. Solar water heating systems use solar panels, called collectors, fitted to your roof. These collect heat from the sun and use it to heat up water which is stored in a hot water cylinder. A boiler or immersion heater can be used as a back up to heat the water further to reach the temperature you want. There are two types of solar water heating panels: evacuated tubes (as in the picture above) flat plate collectors, which can be fixed on the roof tiles or integrated into the roof. Larger solar panels can also be arranged to provide some contribution to heating your home as well. However, the amount of heat provided is generally very small and it is not normally considered worth while. Maintenance costs for solar water heating systems are generally very low. Most solar water heating systems come with a five-year or ten-year warranty and require little maintenance. Once fitted your installer should leave written details of any maintenance checks that you can carry out from time to time, ensuring everything is working properly. Perhaps the most important thing you can check for yourself from time to time is whether there are any leaks. If there are any leaks of anti-freeze (even if you can’t see any liquid) this will have a strong smell. If you notice this you should contact your installer. In general you should keep an eye on your system to check that it is doing what it has been designed to do. If you are not getting hot water or the solar pipework is cold (when the pump is running) on warm, sunny days then again you should contact your installer. For peace of mind some installation companies offer an annual service check. You should have your system checked more thoroughly by an accredited installer every 3-7 years, or as specified by your installer. It is likely that after this period of time the anti-freeze that is used to protect your system in the winter months will need to topped up or be replaced as it breaks down over time reducing the performance of your system. Anti-freeze lasts better if the solar water system is used throughout the year and not left unused during the warmest weeks of the year. This cost of replacing the anti-freezer is usually around ? 100. The other thing that your installer should check is the pump. In a well maintained system, pumps can last for ten years plus and usually cost around ? 90 to replace. Solar water heating systems can achieve savings on your energy bills. Based on the results of our recent field trial, typical savings from a well-installed and properly used system are ? 60 per year when replacing gas heating and ? 5 per year when replacing electric immersion heating; however, savings will vary from user to user. Typical carbon savings are around 230kgCO2/year when replacing gas and 500kgCO2/year when replacing electric immersion heating. Spherical reflector type cooker Spherical mirrors are the simplest type of concentrator and are easy to build and use. It is easy to focus sun rays, and if one opts for a moving vessel to meet the focus, cooking can also be done very easily. Such a design was suggested for the first time in the year 1961 by Stam (1961). He suggested a large reflector of 4. m diameter made of local material which could even include mud, and the reflector surface suitably smoothed with fine mud/cement and coated with aluminized polyester. An appropriate technology handbook describes a simple method of construction of the spherical mirror in the ground (a tall tripod with a long string to which a stone is attached at the tip, will act as a guide for excavating a hollow in the ground) and after finishing and stabilizing the interior, the reflector material could be stuck to make it into a spherical mirror. Such a mirror, of about 2. m in diameter, would do useful work for at least five to six hours a day. The cooking vessel could be hung from the tripod or a suitable stand and positioned to meet the focus. Dan Halacy (1974) suggests a similar design. He uses two full and several half cardboard ribs to fabricate the base and attaches mylar film as a reflector. This device was meant mainly for campers. Bamboo and/or other locally available materials could be used to fabricate such hemispherical baskets. Recently Prof. Quintone of the United Kingdom has taken up this design and is trying to popularize it in places likePeru. In his beautifully designed and illustrated site he presents detailed instructions on fabricating the design and using it. The cooker below is a simple steel bowl used for carrying sand, is coated with a reflector foil and a blackened cooking vessel is put in it. The entire assembly is covered over by a flat sheet glass. The design is very similar toSuryakund cited by Kuhnke et al in their book Solar Cookers in the third world. In Suryakund, the vessels are kept in a inverted glass jar. Like Suryakund, this cooker too would suffer from limitation of size. Unfortunately, this simple design has not attracted much attention, but on a very big scale, like in power generation (as in Marseilles, France), such a hemispherical mirror is being used (Jet Propulsion Laboratory 1981). Scientists ofAustralia (Anon. 1979) have presented a similar design. Margaret Koshoni developed the Cone Cooker to suit the needs of Nigerian women. Most people live in flats with balconies; the structure of the balconies will shade the CooKit and make a shadow. The Cone Cooker being placed on a stand has the advantage of elevation and the stand can be moved about without disturbing the cooking. Medved et al. , propose an interesting design (1996) called a SOLAR BALL. It is an inflatable plastic ball with lower part of reflective material. The cooking vessel is kept at the base. It is an interesting variation but there appears to be some serious limitations with reference to size of the ball as well as size and handling of the cooking vessel. Recently, the spherical geometry seems to have made a come back, and we see that at Auroville in India a 15 meter diameter mirror cooks food for over 1500 persons. A similar large solar bowl was built at the University of Mexico. photovoltaic solar cells PV cells are made from layers of semi-conducting material, usually silicon. When light shines on the cell it creates an electric field across the layers. The stronger the sunshine, the more electricity is produced. Groups of cells are mounted together in panels or modules that can be mounted on your roof. The power of a PV cell is measured in kilowatts peak (kWp). Thats the rate at which it generates energy at peak performance in full direct sunlight during the summer. PV cells come in a variety of shapes and sizes. Most PV systems are made up of panels that fit on top of an existing roof, but you can also fit solar tiles. Solar tiles and slates Solar tiles are designed to be used in place of ordinary roof tiles. A system made up of solar tiles will typically cost around twice as much as an equivalent panel system, although you will save the money you would have spent on roof tiles or slates. Solar tile systems are not normally as cost-effective as panel systems, and are usually only considered where panels are not considered appropriate for aesthetic or planning reasons. Solar PV needs little maintenance – youll just need to keep the panels relatively clean and make sure trees dont begin to overshadow them. In the UK panels that are tilted at 15Â ° or more have the additional benefit of being cleaned by rainfall to ensure optimal performance. Debris is more likely to accumulate if you have ground mounted panels. If dust, debris, snow or bird droppings are a problem they should be removed with warm water (and perhaps some washing-up liquid or something similar – your installer can advise) and a brush or a high pressure hose (or telescopic cleaning pole) if the panels are difficult to reach. Always be careful if you are working above the ground or near the top of a ladder. Alternatively, there are a number of specialist window cleaning companies who will clean solar PV panels for you at a cost (of around ? 30 based on our research in March 2012) depending on the size of your array and location. Many of these companies use a water fed pole system which does away with the need for a ladder. Once fitted, your installer should leave written details of any maintenance checks that you should carry out from time to time to ensure everything is working properly. This should include details of the main inverter fault signals and key trouble-shooting guidance. Ideally your installer should demonstrate this to you at the point of handover. Keeping a close eye on your system and the amount of electricity it’s generating (alongside the weather conditions) will familiarise you with what to expect and alert you to when something might be wrong. The panels should last 25 years or more, but the inverter is likely to need replacing some time during this period, at a current cost of around ? 1,000. Consult with your installer for exact maintenance requirements before you commit to installing a solar PV system. Photovoltaics is the direct conversion of light into electricity at the atomic level. Some materials exhibit a property known as the photoelectric effect that causes them to absorb photons of light and release electrons. When these free electrons are captured, an electric current results that can be used as electricity. The photoelectric effect was first noted by a French physicist, Edmund Bequerel, in 1839, who found that certain materials would produce small amounts of electric current when exposed to light. In 1905, Albert Einstein described the nature of light and the photoelectric effect on which photovoltaic technology is based, for which he later won a Nobel prize in physics. The first photovoltaic module was built by Bell Laboratories in 1954. It was billed as a solar battery and was mostly just a curiosity as it was too expensive to gain widespread use. In the 1960s, the space industry began to make the first serious use of the technology to provide power aboard spacecraft. Through the space programs, the technology advanced, its reliability was established, and the cost began to decline. During the energy crisis in the 1970s, photovoltaic technology gained recognition as a source of power for non-space applications. A number of solar cells electrically connected to each other and mounted in a support structure or frame is called a photovoltaic module. Modules are designed to supply electricity at a certain voltage, such as a common 12 volts system. The current produced is directly dependent on how much light strikes the module. Photovoltaic solar plants work like this: As light hits the solar panels, the solar radiation is converted into direct current electricity (DC). The direct current flows from the panels and is converted into alternating current (AC) used by local electric utilities. Finally, the electricity travels through transformers, and the voltage is boosted for delivery onto the transmission lines so local electric utilities can distribute the electricity to homes and businesses. Solar-Thermal plants work like this: Solar collectors capture and concentrate sunlight to heat a synthetic oil called therminol, which then heats water to create steam. The steam is piped to an onsite turbine-generator to produce electricity, which is then transmitted over power lines. On cloudy days, the plant has a supplementary natural gas boiler. The plant can burn natural gas to heat the water, creating steam to generate electricity. Solar power plants use the suns rays to produce electricity. Photovoltaic plants and solar thermal systems are the most commonly used solar technologies today. ` Solar cells such as these are used in photovoltaic solar technology There are two types of solar power plants. They are differentiated depending on how the energy from the sun is converted into electricity either via photovoltaic or solar cells, or via solar thermal power plants. Photovoltaic plants A photovoltaic cell, commonly called a solar cell or PV, is a technology used to convert solar energy directly into electricity. A photovoltaic cell is usually made from silicon alloys. Particles of solar energy, known as photons, strike the surface of a photovoltaic cell between two semiconductors. These semiconductors exhibit a property known as the photoelectric effect, which causes them to absorb the photons and release electrons. The electrons are captured in the form of an electric current in other words, electricity. Solar thermal power plants A solar thermal plant generates heat and electricity by concentrating the suns energy. That in turn builds steam that helps to feed a turbine and generator to produce electricity. There are three types of solar thermal power plants: 1) Parabolic troughs This is the most common type of solar thermal plant. A solar field usually contains many parallel rows of solar parabolic trough collectors. They use parabola-shaped reflectors to focus the sun at 30 to 100 times its normal intensity. The method is used to heat a special type of fluid, which is then collected at a central location to generate high-pressure, superheated steam. 2) Solar power tower This system uses hundreds to thousands of flat sun-tracking mirrors called heliostats to reflect and concentrate the suns energy onto a central receiver tower. The energy can be concentrated as much as 1,500 times that of the energy coming in from the sun. A test solar power tower exists in Juelich in the western German state of North-Rhine Westphalia. It is spread over 18,000 square meters (194,000 square feet) and uses more than 2,000 sun-tracking mirrors to reflect and concentrate the suns energy onto a 60-meter-high (200 foot high) central receiver tower. The concentrated solar energy is used to heat the air in the tower to up to 700 degrees Celsius (1,300 degrees Fahrenheit). The heat is captured in a boiler and is used to produce electricity with the help of a steam turbine. Solar thermal energy collectors work well even in adverse weather conditions. Theyre used in the Mojave Desert in California and have withstood hailstorms and sandstorms. 3) Solar pond This is a pool of saltwater which collects and stores solar thermal energy. It uses so-called salinity-gradient technology. Basically, the bottom layer of the pond is extremely hot up to 85 degrees Celsius and acts as a transparent insulator, permitting sunlight to be trapped from which heat may be withdrawn or stored for later use.
