JFK Essays (4811 words) - Assassination Of John F. Kennedy

JFK (Part 1 - The first Ricky White News Story) NOV. 22, 1963: ANOTHER STORY BLURS THE FACTS SON OF DALLAS COP SAYS DAD WAS 1 OF 3 WHO SHOT KENNEDY By Andrew Likakis In another bizarre twist to a mystery that has haunted Americans for more than a quarter century, the son of a former Dallas police officer plans to tell the world that his father was one of the assassins of President John F. Kennedy. Ricky White, a 29-year-old, unemployed oil equipment salesman in Midland, says he "had no conception of ever, ever giving this story out" but decided to do so after FBI agents began asking questions in May 1988. "I'm telling you a story that has touched me, not only others, and I feel uncomfortable just telling it to strangers," White said during a recent interview with the Austin American-Statesman. Monday in Dallas, White is scheduled to show reports material implicating his father, Roscoe Anthony White, in the 1963 assassination. It suggests that White, who died in 1971, was a member of an a ssassination team of three shooters, that he fired two of the three bullets that killed the president, and that he also killed Dallas police officer J. D. Tippit during the manhunt for Lee Harvey Oswald. Among the material: a rifle with telescopic sight that uses the same kind of ammunition as Oswald's gun; records showing that Oswald and White served together in the Marines; three faded messages that appear to be decoded orders to kill someone in Dallas in November 1963; and a son's recollections of his father's incriminating diary - a document that is missing. The press conference is being sponsored by two private groups - the JFK Assassination Information Centre of Dallas and the Assassination Archives and Research Centre of Washington - and some Midland Businessmen. The possibility of Ricky White's story being a hoax - a falsehood concocted either by Ricky or his father - has not been dismissed by the people urging him to publicly talk about the matter. During the last 27 years, many private researchers have claimed to have found evidence of a conspiracy, only to be proved wrong or deceitful. Bernard Fensterwald, executive director of the Assassination Archives and Research Centre, says if there was a conspiracy, Ricky White may have the key. "I think it's our best shot," he says, "and we better take it." J. Gary Shaw, co-director of the JFK Assassination Information Centre, says he hopes White's story will result in an investigation of the assassination by Texas authorities. Two Washington-based probes - the Warren Commission in 1963-64 and the House Select Committee on Assassinations in 1976-78 failed to resolve the enigma of the Kennedy shooting, Shaw maintains. As with previous conspiracy theories, White's story is tantalizing, the evidence intriguing. Yet, as with other theories, it raises more questions than it answers -- such as: Who issued the orders to the so-called assassination team? Why was the assassination ordered against Kennedy? And why is Ricky White telling this story now? AN OSWALD CONNECTION Using clues discovered in his father's effects and relying on available government records, Ricky White says he has determined that Roscoe White and Lee Harvey Oswald probably met in 1957. Ricky White's mother, Geneva, is gravely ill and unable to be interviewed, family members say. According to Military records, both White and Oswald were among a contingent of U.S. Marines, who boarded the USS Bexar in San Diego that year for the 22-day trip to Yokosuka, Japan. In its final report, the Warren Commission published a photo of Oswald with other Marines in the Philippines. All but one of the Marines was squatting on the ground. Ricky White says his father claimed to have been the standing Marine and claimed to have become acquainted with Oswald in Japan and the Philippines. Military records show that Roscoe White took frequent unexplained trips in the Pacific, and Ricky White says that his father's diary described those as secret intelligence assignments. It has been established in previous investigations that Oswald was discharged in 1959 and defected to the Soviet Union. He returned to the United States in mid-1962, settling first in Fort Worth with his

Essay on General Electric’s Revolutionary

Essay on General Electric’s Revolutionary Essay on General Electric’s Revolutionary Essay on General Electric’s RevolutionaryHistorically, GE was one of the leading companies operating in the energy industry of the US. However, in the course of time, GE progressed and diversified its operations. By the late 1970s, the company operated in different industries, but its performance was stumbling because after the economic and energy crisis of the mid-1970s, the company confronted substantial problems in its business development. In such a situation, the new CEO of the company, Jack Welch, became a true savior for the company, who helped the company to regain its position and improve its financial and marketing performance. In fact, Jack Welch was one of the prominent CEOs that helped GE to overcome the considerable downturn in its business development and regain its position in the US as one of the largest employers and one of the most successful companies.  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Jack Welch had extensive experience of work within GE, where h e started to work and kept progressing till he reached the CEO position. The personal experience of work at GE was very useful for the company because Jack Welch knew perfectly all the drawbacks and weaknesses of the company that prevented its fast and successful growth. The extensive experience and the understanding of GE, its organizational structure, its strengths and weaknesses helped Jack Welch to determine accurately needs of the company and elaborate the effective strategy that helped the new CEO to make a breakthrough in the business development of GE. The extensive experience of Jack Welch of work within the company became the cornerstone for his further work as the CEO of the company.  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Furthermore, Jack Welch focused on the elimination of bureaucracy within GE that contributed to the consistent improvement of the organizational performance and efficiency of internal business operations. From his past experience of work in GE, Jack Welch knew perfectly that bureaucratic barriers were unsurpassable and they prevented many perspective ideas from their successful implementation in GE. This is why he was aware of the negative impact of bureaucracy on the performance of the company. The elimination of bureaucracy within GE opened the way for the development of effective business policies and helped the company to improve its performance fast.  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In fact, the development of GE under the lead of Jack Welch involved the consistent reduction of the personnel of the company accompanied by the refusal of the company from unprofitable outlets. As a result, the company sold out unprofitable businesses and reduced the staff that allowed to save costs and to optimize its financial performance. The enhancement of the business development occurred due to the focus on profitable businesses only. The company has managed to enhance its marketing performance through the increase of revenue s and decrease of financial losses. Unprofitable outlets of the company were unbearable burden for the company. The sale of those outlets allowed the company to decrease its financial losses and helped to use revenues from profitable outlets to invest into new projects and improvement of their performance.  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Jack Welch fired 10% of bottom managers annually to maintain the competition within the company and keep managers motivated to improve their performance constantly to stay within the company. This strategy was tough but it stimulated the growth of the company because GE managed to improve the financial performance and improve its marketing performance steadily.  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In addition, Jack Welch contributed to the development informal, personal relationships within the organization that also helped to eliminate bureaucratic barriers and improve the communication within the company. The development of inte rpersonal relations and elimination of bureaucratic barriers within GE contributed to the improvement of the organizational culture. The improvement of the atmosphere within the company contributed to the improvement of the organizational performance. Employees worked better in the light of the shift from the organizational performance that was deteriorating because of high bureaucratic barriers to the effective organizational performance.  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Furthermore, Jack Welch diversified the business development of GE by shifting toward financial services from traditional industries, where GE operated. The diversification of the company’s business performance contributed to the enhancement of the position of the company because the company could compensate financial losses in some branches of the company by revenues from others. New industries and new businesses opened wider opportunities for the business development of the company and expansion of its market share.  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Thus, Jack Welch became the CEO, who has managed to reform and reconstruct GE consistently, making it one of the leaders in the US market. Jack Welch became the CEO, who has managed to introduce effective methods of the business development. In such a way, the company has managed to regain its position in the market. Moreover, Jack Welch has changed the business development of the company and the corporate philosophy. As a result, GE became the company with the effective business development, organizational structure and overall improvement of its business performance.

Liberalism and Realism - International Relations Essay

Liberalism and Realism - International Relations - Essay Example Looking from the above text, we can infer the position that realism proposes the understanding that politics is a game played between individuals for their personal gain and that the whole agenda of international politics goes beyond morality, ideology and social reconstructions, and the focus is generally relied upon national security and stability within the political framework of the country. Realism is a pessimistic theory which emphasis the fact that national security and development has to happen due to the competition which the nation state possess from outside its borders, and therefore the need for change and adaptation comes more as a necessity rather than a luxury. A realist sees the world from the perspective of his nation state, where the crucial element is the fact that the nation state has to strengthen its own military and national affairs to compete with the rest of the world as politics is at the state of antagonism. â€Å". A liberal, on the other hand, sees interdependence in the world system, a system in which every state cooperates on some level with other states. This cooperation is facilitated by institutions and established norms and ensures that every state maximizes its gain. Absolute gains, therefore, rather than relative gains, are the focus of liberals.† A liberal is in direct contrast to a realist, as he is an optimistic at heart and sees the nature of politics as a means of building relations with the rest of the world. Liberal internationalism idealises the fact that nation states should intervene in each other’s space with regard to military invasion and humanitarian aid, as well as seeking cooperation with respect to the functioning of the governments in different nation states. The theory emphasises the fact that it is important to have interdependency within the framework of working as nation states and one cannot be isolated it total

Economics Paper - Essay Example On the other hand if the local currency is strong, the foreign rate of exchange will be high thus making company's products to be expensive. At this situation, the company may opt for a domestic market for its products. In domestic market, the company has some power to decide on the price of its products. However this will depend on market structure of its product i.e. Whether it is a perfect competition, monopoly, or duopoly. In perfect competition market, the pricing strategy will be based on the forces of demand and supply of its product, which will be determined by the level of competition from other players in the market. Perfect competition market has a perfect elastic demand curve. Here the market determines the equilibrium price level. At this equilibrium price, the company will sell as much as it can. A slight increase in price will mean the company will sell nothing. In monopoly market structure, the company has the sole power to decide on the price it will sell its product. That is why monopolist is known as notorious in charging higher price of their products. Monopoly can interfere with the demand of its product by lowering it's output here the prices will go up and make more profit. In case of the company being a duopoly, it may collude with the other company that produces the same type of product and charge high prices provided that, there is trust between them. Therefore pricing strategy here will be dependent on trust and cooperation among the two market participants. Question two Most companies are profit maximizing and therefore their core objective is to maximize profit. However others aim at maximizing their sales. Profit oriented searcher will aim to produce the quantity and charge the price given by the point where marginal revenue equals marginal cost. This is as illustrated in the diagram below Price searcher aiming at maximizing sales will produce as a point total cost curve (TC) cuts total revenue curve m (TR) i.e. at the highest point possible. This is as illustrated below. Price searcher aim at maximizing sales, if his intentions are to promote the welfare of the producers i.e. to create the market to the producer's products. In a nutshell, price searcher must therefore choose between maximizing profit and maximizing sales. Question three Elasticity refers to the responsiveness of quantity demanded or supplied due to change in prices or income i.e. Change in quantity demanded or supplied due to a unit change in price or income. In this scenario I would expect demand for a specific brand of running shoes to be less elastic than the demand for running shoes in general. This is because specific brand limits the taste and preferences of a customer. This in turn limits the ability of the customer choice from a wider variety. Therefore a change in price of that specific brand is likely to be highly elastic. Consumers do not have substitute. Demand for a general brand of shoes will be more elastic since customers have

Communication Theory- Article Analysis Essay Example | Topics and Well Written Essays - 750 words

Communication Theory- Article Analysis - Essay Example Through a process of self-disclosure, communication gradually moves from shallow to intimate as a function of immediate and forecast outcomes as the interpersonal relationship develops. The movement from superficial to intimate levels follows the stages of; orientation, where superficial disclosure following social norms and appropriateness are made. The next stage- exploratory affective- entails moderate disclosure on general topics, followed by the affective stage where disclosure of private and personal matters takes place. The stable stage is a plateau level in which personal things are shared and emotions predicted, while the last stage- depenetration- entails a breakdown of the relationship following withdrawal of disclosure (Greene and Burleson 693; Gibbs, Ellison and Heino 152-177). This study analyzes Daniel Chornet-Roses’ â€Å"Using Students’ Prior Knowledge to Teach Social Penetration Theory† in terms of the main purpose, hypothesis, methodology and r esults before arriving at an appropriate conclusion on the implications of the Social Penetration Theory. Analysis â€Å"Using Students’ Prior Knowledge to Teach Social Penetration Theory† Chornet-Rose (150) acknowledges that appreciating student’s existing ideas and beliefs about a given subject enhances the experiences of learning. The scholar seeks to hone the student’s skills in analyzing information, inductive reasoning and self-reflection. To do this, the scholar plans to activate the prior knowledge of the students in relationship development through letting them watch the film Before Sunset. This will be followed by introducing the students to the intended new knowledge in Social Penetration Theory. Although not expressly stated, the hypothesis tested by the scholar is that acknowledging and incorporating the student’s prior knowledge into the classroom enhances student’s learning experience and outcomes. The researcher’s sele cted method comprises of four sections. First, the students were assigned to watch the film Before Sunset at home. The second activity is an in-class one, where the students were required to informally formulate a theory of relationship development through analyzing the film. The study provides a guide towards analysis and inductive creation of the relationship development theory through asking the students to pay close attention to; the type of information shared (superficial, important, intimate); the tone of conversation (serious, friendly, cheerful, angry); non-verbal communication (proxemics, eye behavior); and lastly, the accomplishments of their communicative interaction. The third activity entails a 75-minute in-class lesson introducing Social Penetration Theory, discussing the student’s relationship development theories with SPT and how SPT may be used to discuss relationship development in the theory. In the first 15-20 minutes, the instructor presents a lecture on Social Penetration Theory, highlighting its key concepts. In the next 10-15 minutes, the students discuss and contrast their informal theories with SPT while in small groups. The remainder of the lesson involves the instructor leading the class to discuss the students’ theories in relation to SPT and relationship development in the film. The final activity entails the students writing a paragraph on how their knowledge on relationship development has developed since learning SPT. The essay assignment is given as an end-of-class or

Structure and Function of Biomolecules

Structure and Function of Biomolecules All Biomolecules have certain functions and these molecules all have a unique structure which is why they function in these ways. These molecules are known collectively as macromolecules, these molecules are grouped into four main categories which each have their  own structure. These structures are the key to the macromolecules functions as each of them do a specific task in the body. Macromolecules are grouped into carbohydrates, nucleic acids, proteins, and lipids. In most cases macromolecules are polymers, which is a long molecule which are made by linking together a large number of small, similar compounds called monomers. Polymers are formed by a dehydration reaction, this happens by the -OH group being removed from one monomer, and a hydrogen atom (H) is removed from the other monomer, then the polymer is formed (as shown in Figure 1). This reaction is also used in the linking of fatty acids to glycerol in lipids. This reaction is referred to as a condensation or dehydration reaction, because the reaction produces a water molecule from the -OH and -H groups removed, and for each monomer that is added a water molecule is given off. The opposite reaction is the hydrolysis reaction which breaks down polymer to there respective monomers. Water is added to the macromolecule splitting the bonds between the monomers and the -OH and -H are attached to form the monomers (as in Figure 2). Carbohydrates Carbohydrates are a group of molecules made of carbon, hydrogen, and oxygen in a molar ratio 1:2:1. Carbohydrates have a general formula of (CH2O)n, where n is the number of carbon atoms. These carbohydrates contain a lot of carbon-hydrogen bonds, which releases energy when oxidation occurs, as carbohydrates are well suited for energy storage. Sugars are some of the most important energy sources and they exist in several different forms, such as monosaccharides, disaccharides and polysaccharides. Monosaccharides are the simplest of carbohydrates, they may contain as few as three carbons but the ones that have a key role in energy storage have six carbons. Disaccharides serve as transport molecules in plants and provide nutrition in animals; they are used by plants for transporting glucose around the plant as disaccharides are not easily metabolised, but disaccharides are usually consumed by humans and animals. Polysaccharides provide energy storage, such as starch consists entirely o f ÃŽÂ ±-glucose molecules linked in a long chain. Cellulose is a structural polysaccharide which also consists of glucose linked in long chains, but these molecules are ÃŽÂ ²-glucose. Carbohydrates are used as a source of energy for processes in the body such as muscle movement (Raven et al 2008). Proteins Proteins are linear polymers made up of a combination of 20 different amino acids, which contain amino group (-NH2) as well as an acidic carboxyl group (-COOH). The specific order of amino acids determines the proteins structure and function. The amino and acid carboxyl group go through a dehydration reaction to form a peptide bond which joins the amino acids together to form proteins. Proteins have many different functions which are placed into seven categories; Enzyme catalysis, Support, Defence, Motion, Transport, Regulation and Storage. Enzyme catalysis is when enzymes which are globular proteins with a three-dimensional shape that fit around some molecules to facilitate chemical reactions (Raven et al 2008). Support proteins fibres play a structural role, these fibres include keratin in hair fibrin in blood clots and collagen which forms the matrix of skin, ligaments, tendons, and bones, and is the most abundant protein in a vertebrate body (Raven et al 2008). Defence proteins a re globular and use there shape to recognise foreign microbes and cancer cells, these cell-surface receptors are from the core of the bodys endocrine and immune system (Raven et al 2008). Muscles contract through the sliding motion of two kinds of protein filaments: actin and myosin (Raven et al 2008). A variety of globular proteins transport small molecules and ions. The transport protein Haemoglobin, for example, transports oxygen in the blood stream (Raven et al 2008). Small proteins called hormones serve as intercellular messengers in animals. Proteins also play many regulatory roles within the cell-turning on and shutting off genes during development (Raven et al 2008). Calcium and iron are stored by binding as ions to storage proteins (Raven et al 2008). Lipids Lipids are varied in structure and function, most of them are non soluble in water. Lipids have a very high proportion of nonpolar carbon-hydrogen bonds; so long chain lipids cannot fold up like a protein to sequester their nonpolar portions away from the surrounding aqueous environment. Lipids are hydrophobic so when they are exposed to water there hydrophilic (polar) sections of the lipids cluster together while the hydrophobic (nonpolar) sections gather together with the inside the polar sections to stay away from the water. Fats and oils are a type of lipid which are formed from glycerol and three fatty acids. Fatty acids are long chain hydrocarbons with a carboxylic acid (COOH) at one end. Fats and oils, also known as triglycerides, can be saturated where the fatty acids contain at least one carbon to carbon double bond or they can be unsaturated which means there are no double bonds. Phospholipids are also lipids and they are composed of a polar head, a phosphate group, glycero l, and two fatty acids. Phospholipids form the cell membranes and they use the previously mentioned method for holding together cells. The hydrophobic heads gather towards the water inside and outside the cell forming the membrane, which certain molecules can go through to get inside or outside the cell. Nucleic Acids Nucleic acids are polymers of nucleotides and each nucleotide is made up of a sugar, a base and a phosphate group. Nucleic acids are the information carrying devices of each cell containing the code for all proteins. There are two main forms of nucleic acid which are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Unique among macromolecules, nucleic acids are able to serve as a template to produce a perfect replicate of it. DNA is usually found in the nucleus of cells, which contains the genetic information necessary to build specific organisms (Raven et al 2008). Cells use RNA to read the DNAs encoded information and to direct the creation of the proteins. RNA and DNA are similar in structure and consist of duplicate copies of parts of DNA. The duplicates serve as a blueprint specifying the amino acid sequences of the proteins. In addition to serving as subunits of DNA and RNA, nucleotide bases play other critical roles in the life of a cell. For example adenine is a key co mponent of the molecule adenosine triphosphate (ATP), the energy currency of a cell (Raven et al 2008). Two other important nucleotide-containing molecules are nicotinamide adenine dinucleotide (NAD+) and flavin adenine dinucleotide (FAD). These molecules function as electron carriers in a variety of cellular processes (Raven et al 2008). So Biomolecules have certain functions which they carry out in the body because of there unique structures. These structures are unique as they contain certain bonds between molecules which are all formed in similar reactions. But the four groups of macromolecules are formed in similar reactions, dehydration and hydrolysis reactions, but they all act in different ways.

Fredrick Douglass Essay -- essays research papers fc

The purpose behind Fredrick Douglass’s Narrative was to appeal to the other abolitionists who he wanted to convince that slave owners were wrong for their treatment of other human beings. His goal was to appeal to the middle-class people of that time and persuade them to get on board with the abolitionist movement. Douglass had a great writing style that was descriptive as well as convincing. He stayed away from the horrific details of the time, which helped him grasp the attention of the women who in turn would convince their husbands to help by donating money and eventually ending slavery. He used his words effectively in convincing the readers that the slave owners were inhuman and showed how they had no feelings for other human beings. Although Douglass appealed to the middle-class people, he upset other Northerners at the same time, mainly the slave traders, because he was destroying their business. Through personal anecdotes, Douglass draws an accurate picture of slave l ife. Simultaneously, he chooses these events for how they will affect the Northern audience’s opinion of southern slaveholders (Quarles ii). Douglass uses family relationships, starting with his own birth, to gain the compassion of his target audience. He never knew the identity of his father, but it was â€Å"whispered† (Douglass 2) that it was his master. Douglass mentions this to demonstrate how the â€Å"master in [many] cases, sustains to his slaves the double relation of master and father† (2). This was so...

Disk operating system Essay

MS-DOS (Microsoft Disk Operating System) is a single-user, single-tasking computer operating system that uses a command line interface (CLI). †¢ It also works as an interpreter between user and computer. †¢ The term DOS can refer to any operating system, but it is most often used as shorthand for MS-DOS (Microsoft disk operating system). Originally developed by Microsoft for IBM, MS-DOS was the standard operating system for IBM-compatible personal computers. The initial versions of DOS were very simple and resembled another operating system called CP/M. Subsequent versions have became increasingly sophisticated as they incorporated features of minicomputer operating systems. However, DOS is still a 16-bit operating system and does not support multiple users or multitasking. For some time, it has been widely acknowledged that DOS is insufficient for modern computer applications. Microsoft Windows helped alleviate some problems, but still, it sat on top of DOS and relied on DOS for many services. Even Windows 95 sat on top of DOS. Newer operating systems, such as Windows NT and OS/2 Warp, do not rely on DOS to the same extent, although they can execute DOS-based programs. It is expected that as these operating systems gain market share, DOS will eventually disappear. In the meantime, Caldera, Inc. markets a version of DOS called DR-OpenDOS that extends MSDOS in significant ways. †¢ †¢ Components of MS-DOS †¢ MS-DOS consists of four essentials programs and a set of additional utilities. Four main programs are †¢ Boot Record †¢ IO.SYS †¢ MSDOS.SYST †¢ COMMAND.COM What is BOOTing ? †¢ †¢ †¢ It is a process that starts up a computer. It checks for proper functioning of all the peripheral devices attached with the system. It searches for the operating system and, when located, loads it into the main memory. OR When the computer is switched on, the firmware program in Read Only Memory(ROM) also called Basic Input-Output System(BIOS) reads programs and data i.e. Operating System and loads it into memory (RAM). This process is known Bootstrapping(Booting). The OS once loaded takes control of the computer, handles user interaction and executes application programs. BOOTing Sequence During Booting process, computer loads the operating system into its memory. DOS booting involves reading following files into memory namely IO.SYS, MSDOS.SYS, and COMMAND COM. The Basic Input/Output Program (IO.SYS): This program provides interface between the hardware devices and software of the system. It takes care of the keyboard input, character output to monitor, output to printer and time of the day. The File and Disk Manager Program  (MSDOS.SYS) : It contains the file management and the disk buffering management capabilities. It keeps track of all the disk access of an application program and remains permanently in memory. The Command Processor (COMMAND.COM) : It is also called command interpreter. It is the program that displays the system prompt and handles user interface by executing the command typed in by the user using keyboard. The CONFIG.SYS file : This file contains reference to device drivers which are loaded when OS takes control of the computer. This device drivers are required for configuring operating system for running special devices. The AUTOEXEC.BAT file : This is a special batch program that is automatically executed when the system is started. It can be used to define keys, define the path that MS-DOS uses to find files, display messages on the screen etc. It will be executed only if it exists in the root directory or the diskette from which the system is loaded. Each time the system is started, MS-DOS executes the commands stored in AUTOEXEC.BAT file. One can run it without restarting the system by typing AUTOEXEC at the command prompt. Warm and COLD Reboot Switching on of the computer from Power off and loading the operating system is called â€Å"Cold Boot†. This generally starts with memory test and chips initialization. There may be case when the computer is already on or has hanged up and we want to reboot the system. This is known as â€Å"Warm Boot† and is done by pressing ctrl+alt+del keys simultaneously or just by pressing â€Å"Reset† button on the system. Naming DOS directories and files †¢ †¢ †¢ †¢ There are two name in DOS and is divided into 2 parts. 1. Primary Name 2. Secondary Name or extension. Primary name is separated from the Secondary name/ extension with the help of a dot (.) look at the following example. Example: ENVOICE. TXT †¢ †¢ †¢ †¢ Primary name can be from 1 to 8 characters long. Secondary name contains 3 or less than 3 characters and is optional. The extension tells DOS about what kind of file it is. A valid Character for naming a file are: from A to Z and the digit 0 to 9 Types of DOS commands †¢ C :> Is known as DOS command prompt, where we give the commands. DOS command divided into 2 parts. 1. Internal Commands or Memory-Resident Commands 2. External Command or Disk-Residence Commands †¢ Any instruction given to the computer to perform a specific task is called command. The DOS has several commands, each for a particular task and these are stored in DOS directory on the disk. The commands are of two types : (a)Internal Commands : These are in built commands of MS-DOS i.e. these are stored in Command interpreter file (COMMAND.COM). These commands reside in the memory as long as the machine is at the system prompt(C:>) level. To use these commands no extra /external file is required. E.g. DATE, TIME, DIR, VER etc. These are also called Memory Resident Commands. These commands are automatically loaded into the computer‟s memory during the booting process. They actually included in the Command.com file. So these commands are executable immediately after getting the DOS prompt. Example: mkdir, cd, rd, copycon etc. (b) External commands : These are separate program (.com) files that reside in DOS directory and when executed behave like commands. An external command has predefined syntax. for e.g. HELP, DOSKEY, BACKUP, RESTORE, FORMAT etc. These are also called Disk-Resident Commands. These commands are meant for special purpose. These are found in separate files on Hard Disk or Floppy Disk, hence they don‟t typically consume valuable memory space. They are loaded into memory only when called. Example: xcopy, move, doskey etc. Microsoft Disk Operating System Introduction to the Operating Systems: An Operating system is software that creates a relation between the User, Software and Hardware. It is an interface between the all. All the computers need basic software known as an Operating System (OS) to function. The OS acts as an interface between the User, Application Programs, Hardware and the System Peripherals. The OS is the first software to be loaded when a computers starts up. The entire application programs are loaded after the OS. Whenever an application needs information it requests the OS which in turn queries the System clock on the motherboard. User interacts with the computer through the OS then OS interprets inputs given by a user through the Keyboard, Mouse or other input device and takes appropriate actions. An Operating System can be of Three Types: Single User MS-Dos, MS-Win 95-98, Win-ME Multi User UNIX, Linux, XENIX Network Novel Netware, Win-NT, Win-2000-2003 1. Single User: If the single user os is loaded in computer’s memory; the computer would be able to handle one user at a time. 2. Multi user: If the multi-user os is loaded in computer’s memory; the computer would be able to handle more than one user at a time. 3. Network: If the network os is loaded in computer’s memory; the computer would be able to handle more than one computer at time. Command Prompt Interface: Operating System provides a text based interface called command prompt. From the command prompt commands can be issued to perform file and disk management and to run program. Results of these commands are presented to the user as text message. C:>The command prompt can be an alphabet followed by one colon (:), one back slash (), one greater than sign (>) and one blinking element called cursor (_). Where C: represents the Drive letter (Current Drive) represents the current folder / Directory > represents the end of the Prompt and _ blinking element (represents the Cursor) Always a cursor position decides that the current typed letter from the keyboard will appear on that position. The operating system (OS) is the first program that must be loaded into the memory of your PC before you can use it for any application. You can start your computer with disk operating system (DOS) or some other operating system such as Windows 95, 97, 98 or Windows NT that might be installed in the Hard disk. In this chapter, we shall discuss the basic facilities available in DOS. Switch to MS-DOS and go through most of the text given in this and the next two chapters. If your computer is running under windows 95/98 or Windows NT, perform the following steps to switch to MS-DOS, otherwise move to section 2.1. ï‚ · Click the start button in the taskbar and press the windows logo key to open the start menu then click programs in the start menu. ï‚ · Windows displays the program submenu. ï‚ · In the program menu click MS-DOS Prompt and your screen displays a window that contains MS-DOS Prompt, such as â€Å"C:windows>_†. ï‚ · If you like you can also restart your computer in MS-DOS mode by using the following steps: o Close any open programs o Click the Start Button in the TaskBar or Press the Windows Logo Key to open the Start Menu. o Click â€Å"restart in MS-DOS Mode† and then click OK. Wait for some time and your PC restarts in MS-DOS Mode. After your PC starts in MS-DOS Mode or window, skip the next section and move to section 2.2. What is a File? In computer terminology, file is a collection of text or data stored on a storage device, such as a Floppy Disk or Hard Disk. If you new to computers, it may sound a bit complicated. Well, a computer file is not much different from a conventional paper file that you must have used, or at least seen being used. Just as you stored different types of documents (invoice, letters, reminders, memos etc.) in conventional files, computer files too store information. File Name Each file is given a name so that it can be referred to later. This name is called Filename. The filename in DOS can be up to eight alpha-numeric characters long. Optionally it can also have a period (.) followed by an extension name. The extension name the up to three characters long. For instance, consider the following filename: REPORT2 PROGRESS.DOC Here REPORT2 is a filename. This filename does not have an extension name – „DOC‟. The use of an extension name in a filename is optional. However, the extension name helps in organizing and identifying a file. For instance „DOC‟ may suggest that it is a document file; and „COM‟ may suggest that is a command file. If you use an extension name with a filename, normally you will have to specify the complete file name, normally you will have to specify the complete file name (i.e. including the extension name) while using it with DOS commands. While naming files, you can use the following characters in filename: A- Z, a- z, 0 – 9, @, #, $, %, ^, &, -, _, { },`, ~,( ) You cannot use other characters, such as coma (,) colon (:), semicolon (;), , , /, etc. in filename. Moreover, you cannot use space in filenames. Some examples of invalid file names are: Filename Reason SALE 2 Contains space PROGRESSER Contains more that eight characters MY, File Contains commas CHAP_01.DOC3 Extension name contains more than 3 characters If you use more than eight characters in the filename or more than three characters in the extension name, DOS may automatically truncate the filename by removing extra characters. Further, some file names, such as COM 1, COM 2, LPT1, com and PRN are reserved by DOS for its own use. Therefore, do not use these names to name your file. Also, remember that all DOS application programs including Word, Excel, WordStar, Bbase III PLUS AND Fox Pro follow the same file naming convention. WHAT IS A Directory? As you know, the storage capacity of the hard disk is usually quite large (10 MB to a few GB). You can store hundreds or even thousands of files in your hard disk. Even the capacity of a floppy disk is large enough to store many files. A directory is nothing but a named section of a storage device, such as hard disk, floppy disk. In other words, to organize file on hard disk or floppy disk, these are divided into various segments (sections), called directories. You can store any number of files in each directory. The directory helps to organise your file in an efficient manner. Using directories in a storage devise is similar to keeping different types of files in an office in separate drawers of a filing cabinet. For instant, Xyz Company may keep all sales files in the first drawer, all purchase files in the second drawer and all employees‟ files in the third drawer of a filing cabinet. In the same way, when XYZ Company computerizes its operation, it may store all sales files in the SALES directory, all purchase files in the PURCHASE directory and all employees‟ files in the EMPOLYEES directory. Similarly, the user Raj Kumar may keep his personal files in the RAJ directory and the secretary of XYZ Company may store the letters in the LETTERS or DOC directory. Like a file name, the directory name can also have up to eight alpha-numeric characters. The directory name can also have and extension name up to 3 characters long. However, normally, the extension name is not used with the directory name. When you start your PC, it usually responds with „C :/>‟ and selects the main or the root directory of drive C. Any file that you create or copy to drive  C is added to this root directory. If you continue to add files in the root directory, after a few days, the root directory will have too many files. This will not only confuse you, it will also make the PC slow. The PC may take too long to locate or open the files if there are too many files in a directory. There for you should try to use directories (and sub directories) in your hard disk DOS always creates a root directory in each story device. You can create new directories in the root directory of the hard disk or floppy disk. You can store files in these directories. Moreover, beside files, each directory can also have directories. Those, the file and directory organization in DOS looks like the roots of a tree, as show in figure 2.1.here, the root directory in drive C contains if you files in two directories – WORD and EXCEL. The WORD directory contains a few files as well as a directory TENDER. Sometimes, the second level directory (TENDER in this case) is called sub-directory. The root directory contains another directory – EXCEL. This directory contains a few files as well as two directories – SALES and EMPLOYEE. Both these directories contain files. At any level in the directory structure, can be created. For example, another directory, say FOXPRO directory may contain files as well as more directories. If you want, you can remove files from any directory or more files to another directory. You can also delete an enter directory. Comments to copy, move, rename and delete files and to create and change directories are discussed letter in this chapter. Additional file and directory comments are discussed in the next chapter.

USA Patriot Act essays

USA Patriot Act essays To borrow a term from Shakespeare, the arguments against the U.S. Patriot Act (USAPA) are much to do about nothing. Upon exploration of major concerns regarding USAPA, the arguments made are weak and often over exaggerated claims designed to inflame those concerned with protecting civil liberties. This paper discusses the opponents' major points against USAPA and finds each assertion to be inane or false. The reality is that USAPA simply allows the investigation of all suspected terrorist activity using surveillance common to other criminal investigations and improved communication across government agencies. Opponents of the USAPA argue that the expanded definition of terrorism to cover domestic as well as international terrorism expands the type of conduct that the government can investigate too broadly (How the USA Patriot Act redefines "domestic terrorism). They believe that the government will unfairly use this broader interpretation to monitor the activities of activist organizations such as Greenpeace and Operation Rescue. And, opponents are also concerned that the government can spy or suspected computer trespassers without a court order and can add samples to DNA databases for those convicted of any crime of violence (EFF analysis of the provisions of the USA Patriot Act). The notion that the government should be restricted from investigating domestic terrorism is absurd. Americans were responsible for approximately seventy-five percent of the 335 incidents between 1980 and 2000 that the FBI has classified as suspected or confirmed terrorism (American militant extremists). USAPA defines domestic terrorism as criminal acts that are "dangerous to human life", a category that clearly warrants government investigation. And, accusations that USAPA allows the federal government to secure secret search warrants with no probable cause are not true (Herron, M. an...

Before I Die Communities, Art, Purpose,Reflection A few years ago, artist Candy Chang lost a good friend. The experience left her thinking a lot about death, what in her life was of value, what she wanted to do while she had time, and with whom she should spend those hours.   While she knew she wanted to define these objectives, Chang says that she struggled to maintain perspective.   She wondered if others felt similarly adrift. Chang noticed that there was an old, abandoned home in her New Orleans neighborhood, a perfect canvas for expression. She, along with a group of friends, painted one side of the home in chalkboard paint and created a Before I die ___________________ stencil: Chang had no idea what to expect. But she and her friends attached little baskets of chalk to the sides and stepped away to wait and see: To Changs great delight and surprise, the very next day,   the wall was bursting with handwritten responses and it kept growing:  Before I die I want to†¦ sing for millions, hold her one more time, eat a salad with an alien, see my daughter graduate,  abandon all insecurities, plant a tree,  straddle the International Date Line,  be completely myself†¦. The project did what Chang had hoped it would do and more. It made her feel connected. It focused her thoughts and attention. Moreover, she came to know her neighbors in unexpected ways which were sometimes comic, sometimes tragic. The project soon had many enthusiastic supporters and requests poured in for more of the Before I Die _______ walls. Chang and her colleagues responded by creating a  toolkit  and the  project site beforeidie.cc  to help people make a wall with their community. You can also download all files for free to remix or create your own stencils. To date, one hundred   Before I Die ___________ walls have been created in over ten languages and in thirty countries.   The Atlantic  calls Before I Die _____________  Ã¢â‚¬Å"One of the most creative community projects ever.†Ã‚   Chang, who has given a popular TED Talk on the project, says:   Each wall is a tribute to living an examined life. Our public spaces are as profound as we allow them to be.  The historian Lewis Mumford once wrote that the origins of society were not just for physical survival but for sacred things that offer â€Å"a more valuable and meaningful kind of life.† At their greatest, our public spaces can nourish our well-being and help us see that we’re not alone as we try to make sense of our lives.  Regularly contemplating death, as Stoics and other philosophers encourage, is a powerful tool to restore perspective and remind us of the things that make our lives meaningful.  Each passerby is another person full of longing, anxiety, fear, and wonder. With more ways to share in public space, the people around us can not only help us make better places, they can help us become our best selves. Here are a few more images from the original New Orleans site. You can visit other walls here.   Follow projects on Facebook or Twitter. What do you want to write?

Hinduism - Essay Example Therefore, those that do bad deeds, such as rob or steel, are polluting their karma, which will lead to unfortunate events and vice versa for good deeds. It is also important in the concept of reincarnation, as how good your karma is will determine what an individual is reincarnated as. This is especially important because a person must have very good karma in order to escape the cycle of reincarnation in order to achieve a higher state of enlightenment known as moksha. An avatar is a manifestation of a Hindu deity on Earth. Each sect of Hinduism has a different view regarding these types of manifestations. The manifestation does not have to occur solely as a human, but can be in the form of an animal or any other sort of creature. They appear as a source of divine influence and often speak to people offering sage’s advice. In addition, each avatar has unique qualities, which separate them from one another. Each sect of Hinduism acknowledges the existence of a different number of avatars. In the basics of Hinduism for someone who is unfamiliar to the religion, it would sound unique in comparison to its Christian counterpart.
