Personal Theory - Essay Example , 1986, 115-31) Feminist theory takes the position that the portrayal of the damsel in distress has a profound view on the self-perception as children tend to emulate the characteristics of their favorite characters in children’s literature and attempt to subscribe to their respective character traits. (Zipes, 1989, 185-200) Feminist theory takes the position that the damsel in distress portrays a view of human nature that perpetuates an entirely sexist view of human nature.(Kramer and Moore, 2001) The underlying message is that the female in distress does not have the ability to cope on her own and is dependent upon a males assistance for relief. The view of human nature in this distinction between female and male characterization is exemplified in Cinderella where the damsel in distress is rescued by a Prince Charming who holds out the promise of marriage, status, wealth and happiness. The heroine is helpless and powerless and cannot find redemption without male interference. Sleeping Beauty and Snow White are similar in their respective approaches to this view of human nature in that the heroine is passive and dependant upon the strong, rich and powerful male for redemptive value. Beauty and The Beast puts forward the strong male/weak female view of human nature in a different way. In this fairy tale, the male is aggressive, cruel and punishing and is eventually tamed by the self-sacrificing, beautiful female victim. The female heroine eventually comes to the realization that the male’s cruelty and aggression were all facades for his underlying love for the female and his actual cruel and violent outbursts were merely manifestations of his love for her. (Coward, 1984, 189) Girls who read these Fairy Tales obviously form a distorted view of their perceptions of the female’s role in society. Feminist theory advocates that girls tend to idealize these feminine traits and strive to emulate them. The role of the councilor is to help women who have

Unconscious mind Essay Example for Free

Unconscious mind Essay The word personality originates from the Latin word â€Å"persona† which means mask. From the modern meaning of mask, it means a cover used for disguise. However from the ancient Latin-speaking world, the word is used not to conceal something but to typify or represent a character in theater plays. Thus, personality is what differentiates or distinguishes a person. It is a mask that sets an individual apart from others. For a more detailed description of personality, it is defined as the sum total of the qualities and characteristics of a person as shown in her manner of walking, talking, dressing, and her attitudes, interests, and ways of reacting to other people.   Consequently, to make things simpler and to quote from Glen Allsopp, a popular internet blogger, personality is a set of qualities that make a person distinct from another. Psychoanalysis was pioneered by Sigmund Freud. This perspective believes that there are three levels of awareness or divisions of the mind namely conscious, preconscious and unconscious. Freud represented these levels of awareness through an iceberg. The part of the iceberg visible above the surface is the conscious mind. Just below the surface is the preconscious mind, anything that is not yet part of the conscious mind. Hidden deep below the surface is the unconscious mind, feelings, memories, thoughts, and urges that cannot be easily brought into consciousness. The unconscious can be revealed in dreams and Freudian slips (or slip of the tongue is a verbal or memory mistake believed to be linked with the unconscious mind). In addition, according to Freud, there are three parts of personality called as id, ego and superego. The id works on the pleasure principle. Its goal is instant gratification and satisfaction from our primitive drives related to hunger, sex, aggression, and irrational impulses. The ego works on the reality principle. It protects the person against the immediate gratification of the id. Conscious awareness resides in the ego, although not all of the operations of the ego are conscious. The ego brings the person down to what is real. As an example, when a person is hungry or is sexually  driven, the desire can only be satisfied at the right place and at the right time. The ego controls the person’s actions and allows for higher level cognitive skills. The superego, on the other hand, is the moral center of personality, containing the ego ideal and the conscience, and is the source of moral anxiety. The superego would create perfectionist and civilized individuals that are incapable of compromising what life requires. While the id would create pleasure-seeking individuals whose main goal is to satisfy every desire without delay. The ego balances the person as it compromises what the id desires in accordance to the superego. Carl Gustav Jung believed that there was not only a personal unconscious, as described by Freud, but a collective unconscious as well. This collective unconscious served as a form of psychological inheritance. It contains all of the knowledge and experiences we share as a species. The collective unconscious contains archetypes or models of people, behaviors, and personalities. These archetypes are innate, universal, and hereditary. These are unlearned and function to organize how we experience certain things. The four major archetypes according to Jung are: the self, the shadow, the anima or animus, and the persona. The self is the unification of the consciousness and unconsciousness wherein various aspects of personality are integrated. T he shadow exists as part of the unconscious mind and is described as the darker side of the psyche. It is composed of weaknesses, repressed ideas, desires, instincts, and short comings. The anima is the feminine image in the male psyche while the animus is the male image in the female psyche. It is represented as the â€Å"true self† rather than the image a person projects to others. Lastly, the persona is how we project ourselves to the world. It is like our social mask that we wear for different situations and groups. It shields the ego from negative images. Archetypes are not limited to the four types previously mentioned nor are fixed. Other archetypes that Jung described are: the father (authority figure), the mother (nurturing and comforting), the child (longing for innocence), the hero (champion, defender), and the trickster (liar, deceiver) among others. Psychiatrist Alfred Adler proposed feelings of inferiority as the driving force behind personality and developed the birth order theory. Firstborn children with younger siblings feel inferior once those younger siblings get all the attention and often overcompensate by becoming overachievers. Middle children feel superior over the dethroned older child while dominating younger siblings and they tend to be very competitive. Younger children feel inferior because they are not allowed the freedom and responsibility like those of the older children. Frank Sulloway, another theorist proposed that birth order has a profound effect on one’s personality. Firstborns are more dominant, less open to new ideas, and more conscientious than later-born children. Consequently, later-born children are more open and rebellious.

The Stages Of The Refrigeration Cycle Engineering Essay

The Stages Of The Refrigeration Cycle Engineering Essay The second law of thermodynamics is described as the most fundamental law of science (Khemani, 2008). It is fundamental in the sense that it can be used to explain not only refrigerators and heat engines but highly advanced phenomena such as the big bang. It has been put aptly in the words of Classius as it is impossible for a process to occur that has the sole effect of removing a quantity of heat from an object at a lower temperature and transferring this quantity of heat to an object at a higher temperature (Mortimer, 2008). This essentially means that heat cannot flow spontaneously from a cooler to a hotter body if nothing else happens (Mortimer, 2008) i.e. there needs to be an external agency to effect the change. In kitchen refrigerators, the closed box inside is able to be kept cool by the removal of heat from the inside of the box and depositing it on the outside. Because the heat will not move freely from the cold inside to the hot outside, as by the second law, it is important for it to be made to do so, this is done by using an intermediate fluid (Littlewood, 2004) which absorbed heat on the inside. This intermediate fluid is known as a refrigerant and carries the heat outside of the box whereby it it released into the air as heat as shown in (Littlewood, 2004). Figure 1 the flow of heat within the refrigerator a schematic (Littlewood, 2004) The fluid circulates within the pipe which passes in and out and can be found at the back of the refrigerator. It is kept by using a compressor (which uses electricity from the home) and allows it to work effectively without violating the second law of motion. (Littlewood, 2004) THE FIRST LAW Refrigerator takes in energy from a region that needs to be cooled (or kept cold) and deposits this heat energy into some other region that is outside of the refrigerator. In order to work, there has to be some mechanism in place, where the work done by a compressor and its electric motor is utilized. Using the First Law of Thermodynamics we can write: (Littlewood, 2004) Figure 2 the first law of thermodynamics (Littlewood, 2004) QC   QH  = -W Where: Qc energy or heat of the cold system QH = energy or heat of the hot system W = work done Since work is done on the refrigerator by another device (the compressor), rather than by the refrigerator itself, the work is done is deemed negative because of sign conventions. This is part of the first law (Littlewood, 2004). Suppose that 2.4 MJ of work is used to remove 5.2 MJ of heat from the inside of the refrigerator, then an amount of heat QH  = QC  + W = 5.2 MJ + 2.4 MJ = 7.6 MJ must be added to the kitchen. The refrigerator is termed as a closed system and it possesses a constant composition: U = U + (à ¢Ã‹â€ Ã¢â‚¬Å¡U/à ¢Ã‹â€ Ã¢â‚¬Å¡V) T dV U = U + (à ¢Ã‹â€ Ã¢â‚¬Å¡U/à ¢Ã‹â€ Ã¢â‚¬Å¡T) V dT U = U + (à ¢Ã‹â€ Ã¢â‚¬Å¡U/à ¢Ã‹â€ Ã¢â‚¬Å¡V) T dV + (à ¢Ã‹â€ Ã¢â‚¬Å¡U/à ¢Ã‹â€ Ã¢â‚¬Å¡T) T dT dU (à ¢Ã‹â€ Ã¢â‚¬Å¡U/à ¢Ã‹â€ Ã¢â‚¬Å¡V) T dV + (à ¢Ã‹â€ Ã¢â‚¬Å¡U/à ¢Ã‹â€ Ã¢â‚¬Å¡T) V dT According to Bain (2010), there are four basic parts to any refrigerator: Compressor Heat Expansion valve Refrigerant The exchanging pipes are a coiled set of pipes that is placed strategically outside of the unit. The refrigerant as will be discussed later on is a liquid that has the ability to evaporate efficiently so that inside the refrigerator is kept cooled. (Bain, 2010) A gas can be cooled by adiabatic expansion if the process is enthalphic. The gas expands through a process barrier from one constant pressure to the next and the temperature difference in observed. Insulation of the system made the process adiabatic. The result is that a lower temperature was absorbed on the on a low pressure side and the change in the temperature is proportional to the change in pressure. (Bain, 2010)  Ã¢â‚¬Å¾T  µ  Ã¢â‚¬Å¾P Figure 3 schematic of a domestic refrigerator (Bain, 2010) When an energy |qc| is removed from a cool source at some temperature Tc, and then deposited in a warmer sink at a temperature Th, the change in entropy is: (Atkins dePaula, 2006) Atkins dePaula (2006) also indicated that the process is not spontaneous because the entropy generated in the warm sink is not enough to overcome the loss of entropy from the cold souce. And because of this more energy needs to be added to the stream that enters the warm sink to generated the entropy required by the system. They further indicated that the outcome is expressed as the coefficient of performance, c: The less the work required to achieve a given transfer, the greater the coefficient of performance and the more efficient the refrigerator (Atkins dePaula, 2004). Because |qc| is removed from the cold source, the work |w| is added to the energy stream, the energy deposited as the heat in the hot sink |qh| = |qc| + |w|. Therefore, From: We can have an expression in terms of the temperature alone, which is possible if the transfer is performed reversibly (Atkins dePaula, 2006): Where: c = thermodynamic optimum coefficient of temperature Tc = temperature of the cold sink Th = temperature of the hot sink For a refrigerator, it important that a very low coefficient of performance. For a refrigerator withdrawing heat from ice cold water (Tc = 273 K) in a typical environment (Th = 293K), c = 14. As an example, to remove 10 kJ (enough to freeze 30 g of water), requires transfer of atleast 0.71 kJ as work. (Atkins dePaula, 2005) The work to maintain a low temperature is very important when designing refrigerators. No thermal insulation is perfect, so there is always some form of energy flowing as heat into a specific sample at a rate that is proportional to the temperature difference. (Atkins and de Paula, 2006). Figure 4 (a) the flow of energy as heat from a cold source to a hot sink is not spontaneous. As can be seen, the entropy increase of the hot sink is smaller than the entropy increase of the cold source, so there is a net decrease in entropy (Atkins dePaula, 2006). (b) The process becomes feasible if work is provided to add to the energy stream. Then the increase in entropy of the hot sink can be made to cancel the entropy of the hot source (Atkins dePaula, 2006) he rate at which energy leaks happen is written as: Where: A = a constant that depends on the size of the sample and details of the simulation Tc = temperature of the cold sink Th = temperature of the hot sink The minimum power, P, required to maintain the original temperature difference by pumping out that energy by heating the surroundings is: As can be seen the power increases as the square of the temperature difference (Th Tc). THE REFRIGERATION CYCLE The gas is pumped continuously at a steady pressure, the heat exchanger (which brings the required temperature) and then through a porous plug inside container that is thermally insulated. A phase change heat pump uses a liquid that has a low boiling point to transfer heat from a cooler area to a warmer one, in refrigerators. This heat pump is the most commonly used in domestic refrigerators. It employs a liquid, known as a refrigerant which has a low boiling point. The liquid requires energy (called latent heat) to evaporate, and it drains that energy from its surroundings in the form of heat. When the vapor condenses again, it releases the energy (in the form of heat). A refrigerant is a compound used in a heat cycle that undergoes a phase change from a gas to a liquid and back. Latent heat describes the amount of energy in the form of heat that is required for a material to undergo a change of phase (also known as change of state). Two latent heats are typically described. (Bamb ooweb, 2009)For other uses, see CFC (disambiguation). The pump operates a cycle in which the refrigerant changes state from its liquid form to the vapour form and vice versa. This process occurs repeatedly and I known as the refrigeration cycle. In this cycle, the refrigerant condenses and heat is released in one point of the cycle. It is the boiled (or evaporated) so that it absorbs heat in another point of the cycle. The widely used refrigerant is hydro fluorocarbon (HFC) known as R-134a (1, 1, 1, 2 tetrafluoroethane) and CCl2F2 (dichlorodifluoromethane). Other substances such as liquid ammonia, propane or butane, are be used but because of their highly flammable nature, they are disregarded as a good refrigerant. 1930 (MCMXXX) was a common year starting on Wednesday (link is to a full 1930 calendar). (Bambooweb, 2009)For other uses, see CFC (disambiguation). In the refrigerator the fluid used (e.g. CCl2F2 ) fluid is liquefied by compression then vaporized by sudden expansion which gives a cooling effect. The compressor, in itself does not create a cooling effect directly, as might be expected. The cooling effect is created when the refrigerant absorbs the heat from the cooled space. This is accomplished with a heat exchanger. (Bambooweb, 2009)For other uses, see CFC (disambiguation). A heat exchanger is a device built for efficient heat transfer from one fluid to another, whether the fluids are separated by a solid wall so that they never mix, or the fluids are directly contacted. The refrigeration cycle can be divided in two parts: The liquefaction stage The evaporation stage LIQUEFACTION STAGE The refrigerant vapour undergoes recycling by itself into the liquid form by the extraction of heat from a vapour at a higher temperature. The refrigerant is compressed by the compressor where a low pressure and low temperature condition is created. This is accomplished by an evaporating coil. During the compression process, the vapour of the refrigerant undergoes a temperature change (as an effect of the compression process). Additionally, the work of compression to create the high temperature and pressure vapour also contributes to the temperature change experienced by the vapour. The condenser that is located where the temperature is higher (i.e. the higher temperature heat sink) collects the vapour. Heat is then removed from the refrigerant and in lieu of this it condenses to its liquid state, hence the name for the condenser. Using the Joule-Thompson coefficient: For a perfect gas  µ = 0 Cp + Cv = (à ¢Ã‹â€ Ã¢â‚¬Å¡H/à ¢Ã‹â€ Ã¢â‚¬Å¡T)p (à ¢Ã‹â€ Ã¢â‚¬Å¡U/à ¢Ã‹â€ Ã¢â‚¬Å¡T)p Introducing: H = U + pV = nRT into the first term: Cp Cv = (à ¢Ã‹â€ Ã¢â‚¬Å¡U/à ¢Ã‹â€ Ã¢â‚¬Å¡T)p + nR (à ¢Ã‹â€ Ã¢â‚¬Å¡U/à ¢Ã‹â€ Ã¢â‚¬Å¡T)p = nR EVAPORATION STAGE As the refrigerant leaves the condenser, the next part of the cycle begins. This is accomplishe when a high temperature and high pressure liquid passes through a metering device that is found within the refrigeration. The valve allows a specific quantity of liquid coolant to pass into the evaporation chamber. Evaporation chambers are relatively low pressure and this encourages coolant evaporation. Newly evaporated coolant is drawn though the cooling coils (typically a fan is used to blow air over the coils). Thus, the evaporative process produces the cooling effect. The refrigerant then is pulled to the compressor in the suction line where it will be compressed into a high temperature, high pressure gas and sent to the external heat sinking coils. Capillary action or capillarity is the ability of a narrow tube to draw a liquid upwards against the force of gravity. A refrigerator pumps heat up a temperature gradient. The cooling efficiency of this operation depends on the amount of heat extracted from the cold temperature reservoir (the freezer compartment), , and the work needed to do so. Since a practical refrigerator operates in a cycle to provide a continuous removal of heat, for the cycle. Then, by the conservation of energy (or first law), , where is the heat ejected to the high temperature reservoir or the outside. The measure of a refrigerator performance is defined as the efficiency expressed in terms of the coefficient of performance (). Since the purpose is to extract the most heat () per unit work input (), the coefficient of performance for a refrigerator, , is expressed as their ratio: Where, the conservation relationship given above is used to express the work in terms of heat. For normal refrigerator operation, the work input is less than the heat removed, so the is greater than 1. Refrigerators are commonly referred to as heat pumps of more specifically a it is a reversible heat pump because they basically pump heat. Figure 5 A simple stylized diagram of a heat pumps vapor-compression refrigeration cycle: 1)  condenser, 2)  expansion valve, 3)  evaporator, 4)  compressor. Opening a food refrigerator or freezer heats up the kitchen rather than cooling it because its refrigeration cycle rejects heat to the indoor air. This heat includes the compressors dissipated work as well as the heat removed from the inside of the appliance. The COP for a heat pump in a heating or cooling application, with steady-state operation, is: Where: ΆQcool is the amount of heat extracted from a cold reservoir at temperature Tcool, ΆQhot is the amount of heat delivered to a hot reservoir at temperature Thot, ΆA is the compressors dissipated work. EFFICIENCY The efficiency of a refrigerator (known as the coefficient of performance, COP) is defined as   For example, if 20 MJ are removed from the inside of the refrigerator by doing 7.5 MJ of work, then the coefficient of performance is equal to 20/7.5 = 2.67.

The Life of Christopher Marlowe :: Free Essays Online

The Life of Christopher Marlowe Christopher Marlowe, also known as "Kind Kit" and "The Muses' Darling," is most famously known for being a pioneer in English drama. Introducing blank verse, villain-heroes, and revenge dramas to the stage, Marlowe had a huge influence on other playwrights of that time including William Shakespeare. Marlowe was born in Canterbury in 1564 to John Marlowe, a shoemaker, and Katherine Arthur, a Dover native (Henderson 7). On February 26th that year he was baptized at St. George’s Church in Canterbury (8). During the Elizabethan era, it was important that bright young boys receive proper education. A local philanthropist would usually pay tuition for a boy whose family could not afford it. When Marlowe was accepted into the King’s School, usually for sons of wealthy men, Sir Roger Manwood, a local philanthropist, allegedly paid for his education. When he died, Marlowe wrote a Latin elegy for him ("The Life"). While he was at King’s School, Marlowe studied religious instruction, learned Latin grammar, and Latin and Greek Literature. He was also well studied in ancient and modern history and was encouraged to write Latin poetry and perform plays in Latin and Greek. Upon finishing King’s School, he received a Matthew Parker Scholarship to Corpus Christi College in Cambridge, where he attended from 1580-1587 to further his studies and demonstrate a â€Å"mastery of Latin syntax and grammar.† He received his BA in 1584 to become ‘Dominus’ Marlowe ("The Life"). During the Elizabethan era, many of the best college students were recruited into the Secret Service to protect the Queen and her government. In 1584, after receiving his BA, Marlowe was recruited into the Queen’s Secret Service by Sir Francis Walshingham, England’s Secretary of State. During his time as an agent he gained respect from the Queen and her court, getting recognized as a talented writer. His political insight was â€Å"reflected in his political play about the turmoil in France, The Massacre at Paris† ("The Life"). Marlowe’s most important assignment was uncovering the Babington Plot, aimed at the Queen’s assassination and the assassination of her chief ministers in order to place Mary, Queen of Scots, as England’s Catholic queen.

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.

Free Essays on Star Dust

Star Dust Have you ever wondered how many different objects and particles enter earth’s atmosphere everyday. The earth is growing fatter under continuous microscopic flurry of space specks. The earth gathers 100 tons of space dust everyday. These space particles come from all the over the universe, from the asteroids in the asteroid belt to pieces of distant planets from the dust that was there when our planet was created. By studying these dust particles, astrophysicists say we can learn about our cosmic roots. Cosmic particles are all around us, however, it is near impossible to tell it apart from all the earthly particles in the air. Such things as pollen, pollution, soil, human skin, etc. Not only is space dust hard to see it’s even harder to catch, they are the size of 100 micrometers (Or the width of a hair). To collect space dust scientist have turned to Antarctica. Where there are little to known of earth’s floating particles. The Amundsen-Scott South Pole stat ion draws its drinking water from a well in a cavity of the never-ending ice. As the water is pumped up through a small hole on the surface, the water is heated and shot back down to melt more ice. As the ice melts, it frees the space particles that were in the snowflakes. There was a lot of build up of particles on the well floor. Studying these particles was as easy as throwing a bucket down a hole. Another way dust particles are collected is to attach sticky film to a high altitude aircraft. Once the Astrophysicist have captured the dust, they can determine how fast it entered the earth’s atmosphere thus telling us if it came from a comet, asteroids, or virginal stardust. The Astrophysicist determines the speed of the dust by putting the dust particle in an oven. They rise the temperature until the minerals in the dust particle start to evaporate. If the minerals evaporate at 901 degrees but not at 900 we know that the dust particle was heated to a ma...

Ramifications of the Reconstruction Period essays

Ramifications of the Reconstruction Period essays The reconstruction of the south was the period during and after the Civil War where several different groups in the government tried to solve the economic, political, and social problems that arose as a result of the Civil War. It was a time of disorder and chaos. Southern whites rejected all forms of equality and blacks wanted nothing but full freedom and land of their own. This led to frequent and inevitable riots. Reconstruction lasted from 1865 to 1877 and was one of the most controversial periods in the nation's history. People still debate its successes and failures. Many people blames Reconstruction failure on black politics, calling it "Negro government." Even some newspapers that were in favor of Reconstruction blamed the black legislatures. Foner wrote, "Ironically, even as racism waned as an explicit component of the Northern Democratic appeal, it gained a hold on respectable Republican opinion, as a convenient explanation for Reconstruction's failure." Black politicians could have been the demise of Reconstruction. Another cause of Reconstruction could have been the Court's intervention. Foner stated, "Previously, the court had proved reluctant to intervene in Reconstruction controversies. The Compromise of 1877 between the Republicans and Democrats, occurring in January of that year, was the solution to the contested Presidential election of 1876 and furthermore brought an end to the period of Reconstruction following the Civil War. The banks could have also caused the failure of Reconstruction to speed up. The Freedman's Savings Bank went under with no money to pay its depositors. The bank held thousands of black's (Freedman) money. "In June 1874, with only $31,000 on hand to cover obligations to its 61,000 depositors, the Freedman's Savings Bank suspended operations." One of the main reasons for the failure of Reconstruction was the dropped prices of crops. Many farmers and sharecroppers could not live off what th...

Is Human Cloning Acceptable In Todays Society Essays - Biology

Is Human Cloning Acceptable In Today's Society Essays - Biology Is Human Cloning Acceptable In Today's Society Is Human Cloning Acceptable in Todays Society? Imagine a twelve-year-old girl that has been diagnosed with an illness that will be fatal in the next ten years. This disease targets the heart and slowly deteriorates the myocardium of the heart. The twelve-year-old girl is placed behind fifty people on a list for a heart transplant. For that little girl, there seems to be no faith to which she can depend on for her heart transplant. What options does this girl have besides waiting for a heart transplant or waiting to die? Now, imagine a set of parents who are about to have a baby that was cloned from the father. The parents went for a regular check-up with their doctor and found out that their child was going to be physically retarded due to the cloning of the child. The parents are devastated and outraged that the cloning did not turn out successfully. Unfortunately, the responsibility of raising a physically retarded child has been put into their hands. Would this type of genetic altering be acceptable in todays society? How can cloning a person be ethical if the risks of retardation come into play? These two scenarios draw just a few of the questions that scientists and people all over the world are faced with as human cloning is introduced to the world. In the past few years, many people all over the world have read about the cloned sheep called Dolly. Dolly has been one of the most talked about experiments in the twentieth century. When the concept of cloning emerged, the possibilities that could emerge from it floated in the minds of scientists all around the world. Could we really create an exact copy of any living thing by altering the DNA of the particular organism? To many people, the possibilities are endless but to others, it seems like one of the biggest mistakes that man may have stumbled on throughout our entire human existence. In an article in the The Sunday Times written by Steven Connor and Deborah Cadbury, the issue of human cloning is addressed in a positive way. Scientists have created an embryo of a frog without a head, raising the prospect of engineering headless human clones which could be used to grow organs and tissues for transplant surgery. This type of engineering could bring many answers to questions and problems concerning organ transplanting. With any organ transplant, the patient is required to stay on drugs, which lower the immune system in order to keep the transplanted organ from rejecting its recipient. By using the method that scientists predict will soon be available, the recipient would have no problem accepting the newly transplanted organ. With any type of cloning, the issue of ethical behavior arises. Researchers believe that because without a brain or central nervous system the organ sacs may not meet the technical definition of an embryo. In order to produce the headless frogs, scientists have to pinpoint a certain gene and alter that gene. Fortunately, the frogs could be applied to human embryos because the same genes perform similar functions in both frogs and humans (1A). In Scotland, scientists are trying to create a genetically altered cloned pig that can produce harvestable pig organs that the human body will not reject (Better 19). The cloning of pigs could one day benefit humans but in order to insure success, the headless human clone would be the guaranteed project. This type of cloning could save hundreds of people everyday but it is a question of whether its acceptable or not to the public. In an article from The Atlanta Constitution by Jeff Nesmith, scientists are trying to reach a decision on whether human cloning should be legal and how best to prevent it. The article stresses the importance of how human cloning should not be allowed for the use of parents to clone themselves. At a cloning forum sponsored by the American Association for the Advancement of Science, participants grappled about ethical and moral issues raised by the unexpected appearance of Scotlands cloned sheep, Dolly. At the forum, the total consensus was directly pointed at making the procedure illegal for human cloning. The real question

Ansoff Matrix Research Paper Example | Topics and Well Written Essays - 3000 words

Ansoff Matrix - Research Paper Example Prior to the publication of this book, many organisations at that time had little guidance on how to plan and make decisions for the future; many still relied on conventional forms of planning that involved decisions based on an extended budgeting system which in turn is derived on a projected budgetary outcome to some point in the future (Chartered Institute of Management, 2003). Recognizing the needs of business organisations during his time, Ansoff stated that, "a firm needs direction and focus in its search for and creation of new opportunities and the fact that it is to the firm's advantage to see entries with strong synergistic potential" (Ansoff 1965, p. 104 - 105). Furthermore, Levitt (1960) suggested that in order for an organisation to be successful and grow then an organisation would require a "definitive description" of their role within their environment. However, Ansoff have his own share of critics. Ansoff and Henry Mintzberg have differing views on strategy. In particular, Mintzberg's is averse to Ansoff's view on strategy that is built upon planning (Ansoff 1965, p. 1207). Levitt (1960) elaborated that organisations should have some form of "natural extensions" of the firm's products and markets explaining "natural extensions of the firm's product-market position, derived from some core characteristic of the present business." explaining that businesses in one particular industry, for example railroads, could in fact class themselves as in the 'transportation business (Ansoff 1965).' Ansoff (1965, p. 105) proposed that, in fact, this idea was "too broad" and didn't take into account stakeholders or the "investment Community" understanding or relationship of organisations' future product-market direction or "common thread. He further expanded on this, stating that "a relationship between present and future product-markets which would enable outsiders to perceive where the firm is heading, and the inside management to give it guidance." The common thread in fact was based on three factors according to Ansoff. These are the following: Product-market scope-which identifies the industries to which an organisation limits its product/market position; Growth vector-which is the direction or is an indication of the direction that an organisation is moving towards or with respect to its current product, market position; and Competitive advantage-which is an attempt to understand the properties of individual products markets that will allow an organisation to remain or sustain a competitive advantage. It was through this explanation of the growth vector which elaborates the common thread and the prospective direction of an organisation that becomes the foundation and led to the creation of the Ansoff Matrix otherwise known as the market/product matrix (Ansoff 1965). The Ansoff's Matrix Present New Present Market Penetration Product Development New Market Development Diversification Source: Ansoff, 1965 The matrix as proposed by Ansoff attempts to indicate the direction of organisation product/market posture, through four possible product/market combinations: market penetration; product development; market development; and

Health&Fitness Essay Example | Topics and Well Written Essays - 500 words

Health&Fitness - Essay Example The author is of the opinion that regular moderate exercises can achieve the desired benefits. To support his views, he lists down several benefits that accrue like dramatically lower rates of heart disease, strokes and many others. Simple activities like light walking, mowing the lawn, even if done in bits and pieces, by taking time off in between, go a long way in improving health. Climbing the stairs to one's office rather than taking an elevator or doing a brisk walk from the parking lot are ways that can be done easily, with minimal efforts required. One important thing to note from the article is that simple exercises like mentioned above can be made part and parcel of one's life and hence will reap benefits in the long term. As to how I stand on the article, I would say that I agree with the author's views that regular exercise is important, even if it is not intensive. What usually happens is that one is not able to sustain one's fitness regimes due to commitment that is required. Intensive or rigorous exercises take a lot out of the person and demands considerable effort. So people usually are unable to make daily visits to the gym from a tiring day at the work. Even if they do so they do not have enough time to spare.

Annotated Bibliography Example Special representation needed the presentation of specific goal domain, and complex styles of drawing existed at the commencement of the problems than at later times. Findings from this study are essential as they show how artists can traverse between 2 dimensional and 3 dimensional imagined works necessitating the representation of various spatial coordinates systems, strategic application of drawing styles to help in inferring 3 dimensions dynamic actions. The researchers demonstrate how artists with some form of disability can employ semiotic modalities and various activity goals to infer motion and space. These results are essential to research on tools and knowledge needed to infer motion and space from visual displays, and have implications for artists with disabilities. This paper presents the technological solutions obtainable for enhancing the accessibility of learning materials for individuals with incapacities. The research importantly highlights the design features that computer-based assessments have that can help disabled children. The researchers posit that today’s technologies like assistive devices have emerging strategies that make learning more flexible even for disabled students. Additionally, the research describes developments in the ambient intelligence field that may be essential in educational environments. The research findings are important as they elucidate how individuals with a disability in motor skills can benefit through technological advancements. The findings imply that technologies provide tools that can lead to increased learning capabilities for children without fine motor capabilities. Further, this research implies that children without fine motor capabilities can still venture into graphic design given that they receive sufficient training and essential technological tools. Singh and his colleague explore the percent of children with intellectual

HIV-1 Detection by Western Blot Lab Report Example | Topics and Well Written Essays - 1500 words - 1

HIV-1 Detection by Western Blot - Lab Report Example The antibody when exposed to the enzyme with the substrate will lead to the production of a band that is colored (Luttmann, Bratke, Kupper and Myrtek, 2006). The test is done several times in the positive and the negative control serum to bring the clear identification of the viral protein. In the carrying out the test, there is the consideration of the nine HIV specific bands. When the bands are exposed to the serum of the individual the reaction that occurs in the bands and the patterns is what results to the diagnosis of the individual with the HIV virus. In the experiment to determine the availability of the virus, the polyacrylamide gel is extracted from the tray and the nylon that is used in the experiment is place directly onto the gel. After the nylon membrane is placed on the gel, bands of protein are transferred to the surface of the nylon membrane which makes them to be absorbed by the nylon membrane through the hydrophobic bonds (Wikipedia, 2013). The transfer between the bonds is achieved in chambers that are specially designed through capillary flow or by application of vacuum. DNA and RNA microarrays have been used in the determination of the infection with HIV since they are the key ways in the understanding of the expression of the genes and the method also allow for the rapid quantification of many of the genes once in the given cell that is focused. The microarrays have focused on the determination of the effect of the HIV on the single viral proteins in the individual in the line of lymphoid cells. The microarrays are used in the determination of the HIV due to the instance that the expression of the genes in an individual are always altered during the time of infection with the HIV (Luttmann, Bratke, Kupper and Myrtek, 2006). Infection in the individual is confirmed when the microarrays multiplex leading to the detection and also differentiate the sources that has brought the infection in the individual. In the carrying out of

Music Essay Example | Topics and Well Written Essays - 500 words - 19

Music - Essay Example This is the aspect that distinguishes different artists. There are different genres of music with each having a unique history and features that define it (Patel 182). The preference for each of the genres is also considered as a way of self expression because the different genres convey varying emotions. Emotions that are expressed through music can be categorized into two groups. There are both negative and positive emotions depending on the type of mood that the emotions cause. For example, emotions such as happiness and love are expressed differently from negative emotions such as anger, resentment, grief and remorse. When students are seeking to express any of these emotions in their music, they must be aware that their gestures, body movements, facial expressions, tone variations, tempo and mode of the music as well as the accompanying instruments should be used to enhance the emotions to be expressed. When expressing negative emotions such as resentment and grief, a slow tempo is preferred. On the other end, fast tempo signifies happiness or positive emotions when used in a song (96). In a more specific way, students can use music to express emotions that define their experience as students. For example, students who are victims of bullying can use music to express the anger, resentment and the pain associated with bullying. Evidently, bullying is one of the terrible experiences that students have to handle. Such deep emotions can be expressed effectively using music as long as the student chooses the right features in conformity to the emotions being expressed. Other students have experienced the adverse effects of divorce and can rely on music to narrate their experience (300). One of the highly expressive music genres is the blues category which has its roots in African Americans who served as slaves. A close analysis of different features of the blues category can help students develop

Food and culture Essay Example | Topics and Well Written Essays - 1250 words

Food and culture - Essay Example When people eat, they spend time together and tell stories about life and they plan together for the future. It is a big part of people’s lives. It gives families time to share together and build relationships between family members. Eating food allows passing on customs and traditions that are being forgotten. Food also affects culture in other ways. Human societies are groups of people who interact with each other. But some of the things that make people act the way they do are the food cultures that people grow and share all over the world. Most of the plants and animals people eat grow in a farm. Although many of the food people eat have been there for thousands of years, the ways of growing and raising the food have changed. As ways to farm changed, so did the way land was developed. Understanding food and the environment, people see how the connections of plants and animals had an influence on nature. People then search for ways that agricultural methods can be similar to natural ways. More than 10,000 years ago, humans began the change from hunting and gathering to designing and managing the landscape to serve their needs. People began to control characteristics and develop technology to grow crops and raise animals to fit their tastes. In Guanxi Province in China, for instance, farmers built slopes into step-like terraces (Alba 15). By changing the environment of their surroundings, people can grow food in places that otherwise would not support crops. Preserving food makes it less perishable and easier to transport. Similarly, the obento, a Japanese child’s school lunch, gives cultural messages to a person who is not Japanese. The specific foods and how they are prepared symbolize a connection between home and school. The obento thus plays an important part in identifying a culture (Anderson 103). Early food agriculture helped society grow into cities and states. Anywhere one looks in the world, food affects culture. So

Health Care Financial Terms Week One Essay Example for Free

Health Care Financial Terms Week One Essay Controlling is the practice that managers use to ensure that the company plans and goals are being attained. By comparing report to each other areas that are working and succeeding are defined and the areas where problems are occurring can be addressed and corrected (Baker Baker, 2011). A manager has four different, lets say teams† that report to this manager. Controlling would be when team A, B, C, and D submit the teams’ financial report to the manager. The manager would review all four teams to ensure the teams are meeting the financial goals. So, in this scenario Team A, B, and C is on target and meeting the goals. However, Team D has not met the goals. The manager needs to review the team D’s progress determine where the problem is, such as cutting cost, the resource allocation, operating procedure, or other issues. Without controlling the teams and reviewing progress, other area will suffer. Decision making Decision making is management making informed decisions based on all information that accomplishes the company’s goals (Baker Baker, 2011). The company is making a decision on purchasing electronic medical records. The financial reports will inform management of the financial status on the company and the amount of money they can budget for the purchase of this the EMR. Organizing Organizing is a term for companies to decide how to use resources for the best outcome for the company (Baker Baker, 2011). A manager is given a certain amount of revenue and the manager decides where the money is allocated for the department to accomplish the goals set by the company. Planning To succeed, companies need corporate goals. Planning is identifying the goals and resources. Laying out the steps by using the resources to accomplish those goals (Baker Baker, 2011). A manager has a specific project to install and to perform the primary function of the project. The manager works out a step by step plan from the beginning to the end of implementing the project until the project is complete and accomplishes the goal. Original records When a transaction is recorded into a journal or ledger this becomes the original records (Baker Baker, 2011). A patient makes a payment of $100. This payment is entered into the patient’s file and payment history. This entry is an original record in the company’s income ledger. Reference: Baker, J. J., Baker, R. W. (2011).

Consumer Analysis On Chocolate Consumption Marketing Essay

Consumer Analysis On Chocolate Consumption Marketing Essay The objective of this project is to investigate patterns of chocolate consumption experience. The project will look into different age groups and their consumption habits. The main purpose of this research is to find evidence between age and consumption patterns. And also inspect the extent of chocolate consumptions impact on health. Introduction: The tale of chocolate began at the age of Maya and stretched to the modern world. The Spanish were the first to introduce cacao in Europe and after that it become one of the most celebrated drink of the elite society in Europe until it was mass produced with the help of modern technology. There are different varieties of chocolate available in the market from different companies such as dark chocolate, white chocolate, milk chocolate, sweet chocolate, candy etc. In this project will examine inclination of the consumers towards chocolate consumption (in special context of Nestle, Cadbury Mars chocolates are chosen in the study). The buying behavior is a fascinating study of human psychology. Consumers were generally thought to act rationally, according to neo-classical economics theory ( Howard and sheth 1969) individually maximizing satisfaction of their needs. By contrast, in the modern world, people are more likely to indulge into socio-psychological or emotional or irrational buying motives (Holbrook, and Hirschman 1982). These motives come from the social or psychological interpretation of the product. There are several arguments and also psychological aspects of why a consumer makes a particular choice. According to Freud, persons buying decisions are affected by subconscious motives that even the buyer may not fully understand. The most celebrated work on human motivation is done by Abraham Maslow (1943). He suggested a hierarchical order of human needs. According to Maslow, we seek to satisfy our lower order physiological needs first, before our safety needs, before our belongingness needs, our esteem needs, and finally our need for self actualization. This project will try to find link between human behavior and chocolate consumption. There are past chocolate consumption study which has to some extent examined consumer view, attitudes, and motivations towards chocolate and chocolate consumption as a representative (Belk and Costa, 1998) and social experience (Cova and Pace, 2006). Chocolate consumption can be also related to health problems as many scientific investigations have pointed out. This project will also try to ask questions on common perception on chocolate consumption and its impact on health. Chapter 1: Research aim: This study aims to investigate in the area of chocolate consumption, by exploring how consumers experience chocolate consumption in various circumstances and contexts. It also will try to examine common perceptions of health associated factors related to chocolate consumption. Research objective: The objective of this research is to gain insight in the consumer behavior related to chocolate consumption. This project will try to study existing literature and secondary data and investigate links between consumer behavior theories and the existing data. The further objective is find out perceptions on chocolate consumption and health. As many of the findings and research would suggest close link between them. Chapter 2: History of Chocolate: The story of chocolate begun about 2000 years back in the ancient civilization of Mayan when they discovered the cacao tree ( kah KOW) in the tropical rain forests of South-America. By 1400, the Aztec empire dominated a sizable section of Mesoamerica. They traded with Maya and other people for cacao and sometime traded with cacao seed a form of Aztec money. The ancient Aztecs believed chocolate to be the Food of the god. The history of chocolate in Europe began after the Spanish conquest of Mexico in 1521. It is believed that Christopher Columbus first European who discovered existence of cacao tree. It is also believed that It was him who brought back some cacao trees from Spain. (http://www.sfu.ca/geog351fall03/groups-webpages/gp8/history/history.html) The Spaniards quickly recognized the value attached to cacao and observed Aztec custom of drinking chocolate. Soon after Spanish started to ship back the cacao seeds and started to sweeten the cacao with cinnamon, sugar and other sweeteners. Xocolatl! or Chocolat or Chocolate as it became known was introduced to Europe by Cortez, later as the time progressed Europeans were able to make the drink more palatable for European taste thus changing the Aztec style of drinking. The first chocolate factories opened in Spain and by the early 17th century chocolate powder from which the European version of the drink was made and exported to different parts of Europe. Spanish managed to keep their drink secret for almost 100 years before rest of the Europe find out about the drink. The Spanish kept the source of the drink the beans a secret for many years, so successfully in fact, that when English buccaneers boarded what they thought was a Spanish Treasure Galleon in 1579, only to find it loaded with what appeared to be dried sheeps droppings, and burnt the whole ship in frustration, if only they had known the value of chocolate. Within a few years, the Cocoa beverage made from the powder produced in Spain had become popular throughout Europe, in the Spanish Netherlands, Italy, France, and Germany and in about 1520 it arrived in England. The first Chocolate House in England opened in London in 1657 followed rapidly by many others. Like the already well established coffee houses, they were used as clubs where the wealthy and business community met to smoke a clay pipe of tobacco, conduct business and socialize over a cup of chocolate. For centuries, chocolate was eaten by the societys upper crust. But by the 19th century mass production of chocolate helped it reach much wider portion of society. First European chocolate factory was set up France 1761 in the town of Bayonne. As demand increased most of the European countries started producing cacao in their colonies in Caribbean, Africa and parts of South East Asia. (Simmons, 1976; Baker, 1891) 1828 marked the modern ear of chocolate making when Dutch Chocolate maker Conrad J. van Houten patented an inexpensive method for pressing making cacao powder. Many chocolate companies of today were formed as a family run businesses such as Europe such as Van Houten in the Netherlands in 1815, Menier in France in 1824, Cadbury and Rowntree in England; and Suchard, Nestlà ©, Lindt and Kohler in Switzerland. (http://www.chocolate-source.co.uk/history_of_chocolate.htm) http://www.sfu.ca/geog351fall03/groups-webpages/gp8/history/timeline.jpg http://www.sfu.ca/geog351fall03/groups-webpages/gp8/history/history.html This figure shows the evolution of chocolate from being produced in form of cacao in South America and then eventually in Europe. In 1894, English chocolate maker Joseph Storrs Fry produced what was arguably the worlds first eating chocolate (Brenner, 1999; Spadaccini, 23rd online edition). Some of Englands most successful entrepreneurs during the Industrial Revolution belonged to a group of people known as The Society of Friends, or more commonly, the Quakers. Due to their radical beliefs, the Quakers were alienated from many of the mainstream professions of the time including politics, law and medicine. Many of the large Quaker families channeled their energy into business and commerce, and one of the most progressive commodities at the time to invest in was cocoa. A one man business opened in 1824 by a young Quaker, John Cadbury, in Bull Street Birmingham was to be the foundation of Cadbury Limited, now one of the worlds largest producers of chocolate. In 1831 the business was transformed from grocery shop and John Cadbury was manufacturing drinking chocolate and cocoa. This was the start Cadburys business as it is known today which was later joined by John Cadburys brother Benjamin and the business become Cadbury brothers in 1847 in Birmingham where they rented their first factory. This partnership dissolved in 1860 and a year later John Cadbury retired leaving his sons Richard and George, the second Cadbury brothers, to continue the business. 1866 saw a turning point for the company with the introduction of a process for pressing the cocoa butter from the cocoa beans. This not only enabled Cadbury Brothers to produce pure cocoa essence, but the plentiful supply of cocoa butter remaining was also used to make new kinds of eating chocolate. Business prospered from this time and Cadbury Brothers outgrew the Bridge Street factory, moving in 1879 to a greenfield site some miles from the centre of Birmingham which came to be called Bournville. The opening of the Cadbury factory in a garden also heralded a new era in industrial relations and employee welfare with joint consultation being just one of the initiatives introduced by the pioneering Cadbury brothers. In 1899 the business became a private limited company Cadbury Brothers Limited. Progress since the start of the century through the inter-war years onwards has been rapid. Chocolate has moved from being a luxury item to being well within the financial reach of everyone. The story behind many of todays chocolate manufacturers begins with a Quaker family the Cadburys, the Frys, the Rowntrees and the Terrys all chose cocoa as the basis for their family businesses. Their aim was to persuade the poor to give up alcohol in favor of the healthier chocolate drink. Because of the persecution the Quakers faced in England thousands migrated to America and settled in the colony of Pennsylvania founded in 1682 by William Penn. By 1864 seven thousand Quakers had settled their including one Milton Hershey and by 1900 the Hershey chocolate factory was up and running.

Mars Background Mars UK is a division of Mars Incorporated, a family-owned US based business with annual revenue of over $30 billion. The company acquired Wm Wrigley Jr in 2008, extending its food and drink portfolio in the UK to cover chocolate and sugar confectionery and gum, ice cream and petcare.( www.mars.co.uk) The companys key brands in the UK chocolate confectionary market are Galaxy, Maltesers, Mars, Snickers, and Twix. Kraft Foods UK Background Kraft Foods is a US-based multinational confectionery, food and beverage conglomerate which supplies biscuits, cheese, grocery, chocolate, coffee, gum and candy. It has its presence over 50 countries worldwide. The company strengthened its leading position in the chocolate confectionery market when it acquired Cadbury Plc in January 2010 for  £11.5 billion and in doing so, acquiring the likes of Dairy Milk, Roses and Twirl, as well as inheriting the premium organic brand, Green Blacks. In March 2012, the company announced its plans to remain at the forefront of NPD by investing  £17 million into research and development in the UK. Kraft also launched Green Blacks an exclusive chocolate bar in support of Breast Cancer alertness month. The new Raisin Hazelnut bar in a pink package came with the Breast Cancer ribbon and the charity organisations logo. The company unveiled the limited edition bar in October 2011 and contributed  £20,000 to help Breakthrough Breast Cancer in its research work. (www.greenandblacks.com), (www.cadbury.co.uk), (www.kraftfoodscompany.com) Nestlà © Background Nestle UK Ltd is a division of the Swiss nutrition, health and wellness company Nestlà © SA. The UK business operates 15 manufacturing units and has three major subdivisions food and beverage, confectionery, and Nestlà © Nutrition. The brand claims that it is planning to invest  £500 million into the UK market from 2012-14. The company manufactures and markets a wide range of products in various markets such as Pure Life (bottled water), Cheerios (breakfast cereals), KitKat (chocolate confectionery), Nescafà © (coffee), Herta Maggi (family meals), Carnation (evaporated condensed milk) and Nesquik (flavoured milk).( www.nestle.co.uk) Market Share of Different companies and future: According to the Manufacturers shares in the UK chocolate confectionery market, by value, 2011 Kraft, Mars and Nestlà © hold three quarters of the market share (Source: Mintel) These are top three companies which hold account for 76% of sales via their wide portfolio of brands. This market is considerably more dependent on the fortunes of its top three companies than the sugar equivalent. ( Mintels Sugar Confectionery UK, November 2011 report). According to the same report Cadbury Dairy milk and Mars Galaxy is reckoned to be the two most popular brands in UK market. Both of them occupying almost 20 percent of the market share (Appendix: Table ) although there is a significant percent of change in Dairy Milks fortune. UK Leading brands purchased in the UK chocolate market, 2008-10, Chocolate Confectionery UK April 2011 Market Share According to Euro-monitor Chocolate is still the UK market leader with accounting 31% of the value sale.. Euromonitor International (2011) Chocolate confectionery data spreadsheet (Euromonitor International Limited, London) 2010 data for total size of global retail chocolate confectionery market, using fixed 2010 exchange rates, in current prices 2009 data for company share of global market Reports from Mintel also suggests that despite Dairy Milk being the only brand in top ten its presence is felt through in the chocolate confectionery market through a strong promotion and this brand which is comfortably the market leader, with 12% of total chocolate confectionery sales. Krafts takeover of Cadbury in 2010 significantly boosted the companys presence in the UK chocolate confectionery market, up from around 5% to its current status as leader with a third of the total market share. (Mintel Chocolate Confectionary Report 2011) According this report Mars is the second largest company in the chocolate confectionery market having a market share of 27%. The company achieved reasonably strong sales growth of 7% in 2011, despite this its largest brand, Galaxy, and flagship Mars bar brand both saw sales fall in 2011. Galaxys performance is mostly surprising as the brand has in fact carried out many activities which should promote growth such as a significant advertising spending, however Galaxy sales dipped by 3% although it is worth noting that this comes on the back of a particularly strong performance in 2010. It also states that Nestlà © holds a prominent share in the market as the third company which has a notable existence in the chocolate confectionery market. and holds a 16% share through a portfolio of well-established brands such as KitKat, Aero and Quality Street. Although the company has four brands inside the top 15 in the market, it currently lacks a marquee chocolate brand of same level as Cadbury Dairy Milk or Mars Galaxy. According to the Mintel report since 2006, the chocolate confectionery market has grown by 21%, with stable growth of 4-6%. The UKs fondness for chocolate has meant that it has been largely unaffected by the post-recession landscape, with sales reaching  £3.98 billion in 2011. The growth has increased on the back of inflation, with rising retail prices helping to drive value sales but suppressing volume sales, despite regular promotions. However rising prices pose a possible threat, leading to 49% of consumers claiming that they may slash back in this scenario. But considerable support for brands such as Kraft and Mars is likely to keep users engaged with the market, while the own-labels are now making concerted efforts to grow their small share (7%) of sales. The market is forecast to continue rising at between 5% and 6% in the coming years, reaching  £5.25 billion by 2016. The chocolate confectionery market continues to achieve steady growth.

In recent years, yearly growth in the market has lingered at around the 5% mark, a trend expected to continue in the years up to 2016. In 2011, the market reached  £3,976 billion, a 21% increase over a five-year period. Apart from 2012 which may benefit from a halo effect around the London Olympics and European Championships growth is predicted to only be around 1% at 2011 prices, highlighting the continued impact of inflation. This report also forecasted that the market is expected to continue benefiting from its desirable position as a standard and inexpensive treat eaten by nine in ten (89%) of the UKs population, with four in five (81%) weekly users. However, there is a danger that rising prices with static or decreasing bar sizes will deter users, with 49% admitting that they would cut back if prices kept on rising. The increasing cost of the bars also cover the fact that, in terms of volume sales, the market size in fact declined somewhat in 2011, despite the frequency of a soaring number of promotions. In fact, growing prices are inescapable for chocolate manufacturers as they have to deal with rising commodity prices in recent years. However, a positive harvest in 2011 perhaps opens the door for companies to shine their value credentials by tackling rising prices head on, something which there is a strong consumer demand to see. MIntel report has mentioned a word of caution for the big three brands (Kraft (Cadbury), Mars and Nestlà ©) which account for three quarters of sales, a growing number of niche brands, particularly at the premium tier, and a fight back from own-label options, look set to increase competition in the coming years. Forecast Forecast of UK retail value sales of chocolate confectionery, 2006-16 ( Mintel ) Source: MIntel Forecast methodology: Mintel has created this estimate based on an sophisticated statistical technique known as multivariate time series auto-regression using the statistical software package SPSS. The model, based on past market size data taken from Mintels own market size database and complemented by macro- and socio-economic data sourced from trustworthy organisations (eg Office for National Statistics, HM Treasury, Bank of England), searches for relationships between actual market sizes and a selection of key economic and demographic factors (independent variables) in order to recognize those determinants having the most influence on the market. Chapter 3: Literature review Introduction: In this section of the project buying behavior will be explored with the help of theory and examples. Many of free market economists and policy makers believe of customer centric approach who will purchase according to their choice. (Consumer behavior, Ray Wright, Thompson Learning 2006). Chocolate is a very popular consumer product bought for many different occasions and reason. There is thus some truth in a popular remark like, Nine out of 10 people like chocolate. The tenth person always lies, or Chocolate makes everyone smile-even bankers (Doherty and Tranchell, 2007). Buying behavior of consumers: The consumer decision-making process is significant in determining buying behavior. In order to offer an efficient service, it is important to categorize consumer segments, taking into account the benefits which the consumer seeks. Consumers seek benefits or solutions, not products (Rowley, 1997). The main reason behind consumers search is indecision. Consumer information search has been the focus of many articles studying consumer behavior during the last 30 years (Bettman, 1979). Perceptions of food quality and safety are likely to be influenced by psychological and cultural factors rather than physiological product experiences alone. Many quantitative and qualitative researches have attended to issues connected with cultural determinants of food choice (Shepherd and Raats, 2007). It is quite evident from such studies that while analyzing factors that influence food choice, it is important to consider consumers cultural background (Overby et al., 2004; and Hoogland et al., 2005). It is believed that people from different cultural backgrounds have different perceptions and experiences related to food (Lennernas et al., 1997). Hence it can be noticed that some consumers are more oriented towards food quality, whereas for others food safety is a concern. Consumer behavior is also affected by the socioeconomic conditions of the markets namely, income, mobility, media access (Tse et al., 1989). It has been observed that per capita income and disposable income indicates the amount of resources consumers allocate to consumer goods (Johansson and Moinpour, 1977). According to Maslow, we seek to satisfy our lower order physiological needs first, before our safety needs, before our belongingness needs, our esteem needs, and finally our need for self actualization. The hierarchy is shown in the figure below: Let us simplify the pyramid of need a little bit more: physical, social and self. The physical needs relates to the basic and psychological needs of person. Basic need means a person buys food when he is hungry, buys house for his shelter and so on. Buying house is also falls into safety needs. Psychologically a person feels comfortable, when he/she has a house, of his/her own. What is a social need? Social need is driven by persons status, self-esteem, prestige, family belongingness. From luxury items to particular brands, the decision to purchase a particular product is frequently based on deeper psychological influences, oftentimes influencing brand loyalty according to psycho-social interpretation of product value (Fine, L.M. : Business Horizons 2010). It is very difficult to generalize the need motivation theory, because geographically people are different from each other. For example, as the heroes of Hollywood movies amply show the typical Anglo-Saxon cultural values, which pu ts individuality and self-actualization above all else, but that is not universally so. In Japan and German speaking countries people are mostly highly motivated by need for personal security and conformity, while in France, Portugal, Spain, other Latin American and Asian countries people mostly motivated by the need of security.( Gert Hofstede, Cultural Consequences ( London: Sage 1984)) The theory of planned behavior ( Azjen, 1991) argues that our intentional behavior is not always similar as our actual behavior, and sometimes how our attitude towards the behavior, subjective norm and perception about the behavior control our actual behavior. For example, alcohol consumption is different in different countries, depending up on the psychological perception about alcohol drinking. Here we also consider others opinion and the impact of drinking alcohol on our family and children. Consumers can act on beliefs. Belief can be defined as quick response; we will give about a matter. They are held with limited conviction and do not support the facts most of the times. Attitudes in comparison are held with greater degree of conviction for longer period; it is much likely to influence buying behavior. For example, when we see new advertisement about a product, say new shoe from Adidas. We believe that shoe would to good and comfortable to wear. Beliefs are based on more of emotional aspects on the contrary to attitudes. Attitude evaluates the product, based on the usage of the product. Now the attitude towards the Adidas can be positive or negative. May be there is no change in design or maybe it is not that comfortable to wear. So here attitude would be negative. Value is another very important factor influencing behavior. Peoples value grows from the childhood. The social and regional atmosphere, ethnicity, culture and sub-culture, religion all contribute to value creation in a person. Consumers often are influenced by their parents and friends. It may have a positive or negative influence on the buying. For example, a young man loves sports bike, well his father and uncle used ride one, and his friends also do. But after a serious accident of his uncle riding a sports bike made his father against him buying a one for himself. But he may or may not buy a sports bike after all. He may feel that his freedom is blocked, partially or fully and motivated to go against it. Social grade, status or lifestyle is based mainly on the income of a household. It can influence buying pattern. For example, champagne is more of a high cost drink. It was found in a survey that large proportions (44%) of champagne drinkers are professional and managerial class. By contrast, 22% working class people and only 14% who are unemployed drinks champagne. So there is a marked decrease in champagne consumption as we move down the socio-economic scale. (Source; Mintel 2008b) How customers buy: From companys prospective any communicating massage, while at the time of purchase or other point can have direct impact on consumer behavior. For example, most of the food commercials are shown at the time of our breakfast or dinner. So marketers are giving specific massage at a particular point. Although there are variety of models of consumer buying behavior, the consumer product proposition acquisition model is perhaps the simplest to understand, stressing how the consumer goes through six key stages in product acquisition process including motive development, information gathering, product evaluation, product selection, acquisition and re-evaluation.( Baines, Fill, Page pg 113) The consumer proposition acquisition process or buying process consists of six stages. Explained in the figure below: Motive Development Information Gathering Proposition Evaluation Proposition Selection Acquisition/Purchase Re-evaluation The consumer proposition acquisition process (Baines, Fill, Page pg 83) Motive development: the model begins with when we decide to purchase or we need to acquire the product. It begins with our understanding that some problem needs to be solved. For example, a young male consumer decides to gift a box of chocolate to his wife. He might have bought Cadbury dairy milk or he might opt for premium brands such as Throntons or Godiva. Information gathering: the next stage of process will require us to look for alternative ways to solve our problem. Our search for a solution to solve problem may be active or passive, in other words, we are open to ways of solving our problem but we are not actively looking for information to help us (Howard and Sheth, 1969) Search for the information may be internal; when we think we already know the problem and identified the products that will solve them. Or, external where we dont know enough about our problem and seek supplementary information to help us to decide. Now buyer access to information, feedback, and peer reviews has increased; this has increased through social networking sites and internet. With so much to choose from, customers have increasing become intolerant about products or services. The consumer has the right to choose and this continues to impact buying behavior and consumer loyalty. So by the right communication about the product with its added features, co mpanies can build a sustainable relationship with the consumer. Proposition evaluation: once we feel that we have sufficient information and we now can make a decision, we evaluate the proposition. These evaluations can be rational (e.g. based on cost) or irrational (e.g. based on emotional desire). For example, the young man buying a box of chocolate exemplifies his emotional desire to please his partner. Proposition selection: in major cases, the proposition we eventually select is the one we believe is fitting our needs best beforehand. However we might change on a particular proposition from where we buy it. For example, the man buying the box of chocolate may have been checked the stock online for a particular retailer but when he turned up at the retail shop, the brand he wants to buy is not there, so he then and there decides an alternative. The person may go to another retail shop or he may buy another similar kind of product from the shop, because what he wants to buy is not available. This is why proposition selection and evaluation are different stages of buying process. Acquisition/purchase: Once selection has taken place, different approaches are there for proposition acquisition. For example, there is always an emotional aspect attached when we are making an infrequent purchase. Family as a whole can act as a single most influencing factor, where wifes and childrens influence most of the buying decisions. Re-evaluation: The theory of cognitive dissonance (Festinger, 1957) suggest that we are motivated to revaluate our beliefs, attitudes, opinions, or values if the position we hold on them at one point of time is not same as we held an earlier point, due different actions, circumstances and intervening events. Experience can clash with expectation which can create buyer remorse. People may feel angry, guilty, surprise or embarrassment. People are biased to think that they have made right choices despite the contrary evidence which gives dissonance theory new light on otherwise puzzling behavior The consumption experience can be described as an emergent property that results from a complex system of mutually overlapping interrelationships in constant reciprocal interaction with personal, environmental, and situational inputs (Hirschman and Holbrook, 1986, p. 219). It depends when food
