Psy 104 Final Paper Essay Classical conditioning is a developmental theory introduced by a man by the name of Ivan Pavlov. Ivan Pavlov was born on the 26th of September in 1849 in a town called Ryazan in the country of Russia. Ivan Pavlov’s father was a priest and Ivan was the oldest out of 11 children. When Ivan was seven years old he had an accident where he fell from a balcony onto his head. Because of the injuries he sustained from the fall Ivan had a hard time with academics and was kept out of school till he was eleven years old. Ivan Pavlov went to college at St. Petersburg University and was originally going to school for science but since he was bad at math he decided to go for physical science. He ended his schooling in the Academy of Medicine. Before Ivan Pavlov went on to develop his theory of classical conditioning â€Å"In 1904 he was awarded the Nobel Prize for his researches into the neural mechanism by which the secretion of gastric juices was stimulated. † (Harre, 2006) Classical Conditioning is a process of behavior modification by which a subject comes to respond in a desired manner to a previously neutral stimulus that has been repeatedly presented long with an unconditioned stimulus that elicits the desired response. Ivan Pavlov liked to test his theories out on animals mainly dogs. An explanation of his studies with dogs is â€Å"In this type of learning, a neutral stimulus is paired with a stimulus that naturally elicits a response. For instance, a lab coat would not ordinarily bring any response—it is a neutra l stimulus; food naturally elicits a salivary response. When the lab coat is paired with the food repeatedly and learning is complete, the lab coat is no longer neutral. The dog has learned to associate the lab coat with food, even when no food is present. The former neutral stimulus (lab coat) now elicits the response (salivation) even in the absence of the original stimulus (food)† (Mossler, 2011) Another example of classical conditioning is â€Å"John B. Watson and his assistant, Rosalie Raynor, invented a different version. They quickly taught an infant named Little Albert to fear a white rat by banging a loud gong just behind the tot whenever the rat appeared. After just seven gongs, Little Albert was scared to death of the same rat he had played with before the training began. His fear was so great that it generalized to other furry objects, including a Santa Claus mask. (Johnston, 1999) The Second developmental theory I will be discussing is Jean Piaget’s cognitive theory. Jean Piaget was born on the 9th of August in 1896 in Switzerland. His father was a professor of medieval literature at the University of Neuchatel. Jean Piaget was originally interested in zoology and by the age of 15 he had written several artic les on mollusks. Jean Piaget went to the same university that his father taught which was the University of Neuchatel and he also studied at the University of Zurich for a small amount of time. Jean Piaget changed his interest of oology. â€Å"Piaget’s interests turned to child cognitive development while working to standardize tests for schoolchildren. At this time, he witnessed a pattern among children’s correct and incorrect answers, leading him to develop a theory of the stages of understanding through which a child’s cognition passes. He quickly established a clinical method of study, involving not only observation but also verbal interaction with the child subjects of his research. Piaget’s writings on the subject attracted much attention initially and then fell into obscurity for many years. Upon publishing detailed analyses of his work involving his three children, his work once again received wide recognition in the field† (Edinburgh University Press, 2005) Jean Piaget’s theory was his idea that children learned through stages which each one was crucial into leading the child into the next stage of development. Jean Piaget’s theory was broken down into four stages. Those stages are sensorimotor stage, preoperational stage, concrete operations, and formal operations. Each stage is very important to the development of a child and I will explain each one. The sensorimotor stage is the first stage of Jean Piaget’s theory in which† infants gain cognitive understanding primarily through their senses and movements, which are coordinated through reflexes. † (Mossler, 2011) The second stage of Jean Piaget’s theory is the preoperational stage which lasts from ages two to seven. This is the stage where children begin to acknowledge the world through mental structures and symbols. Children learn to play make believe and learn to speak whatever language they are being taught by their parents. They use inadequate logic because at this time they can only view things with one perspective. The third stage of Jean Piaget’s theory is called concrete operations which lasts between the ages of seven and twelve. This is the stage where a child’s thought is guided by logic and they have learned to view things from multiple perspectives. The fourth and final stage is called formal operations. This stage lasts through adulthood and is the stage where children begin to learn complex forms of thought such as being able to hypothesize, think of complicated plans, and accurately predict outcomes. An example of Jean Piaget’s theory is â€Å"in order to understand behavior and outcomes, an infant may experiment by throwing food. The infant gets to understand how the explosion of food behaves as well as the potential explosion by parents. Because adolescents have more sophisticated cognition, they can understand the consequences of throwing food—both what it might look like and the reaction of others—without actually experimenting with the behavior. † (Mossler, 2011) The third and final developmental theory I will be discussing is Albert Bandura’s social-cognitive theory. Albert Bandura was born on the 4th of December in 1925 in Mundare, Alberta, Canada. Albert Bandura went to college at the University of British Columbia where he got into psychology by accident because he had no classes in the morning so he decided to take a psychology class. He got his B. A in psychology. Albert Bandura then went to get his M. A at the University of Iowa Social Cognitive theory is a theory that states that portions of an individuals knowledge acquisition can be directly related to observing others within the context of social interactions, experiences, and outside media influences. What I am trying to say is, people do not learn new behaviors solely by trying them and either succeeding or failing, but rather, the survival of humanity is dependent upon the ability of people imitating and replicating the actions of others. Depending on whether people are rewarded or punished for their behavior and the outcome of the behavior, that behavior may be imitated. An example of Albert Banduras social cognitive theory is â€Å"study influences on aggressive behavior in children, during which children were shown to imitate, without prompting or incentive, aggressive adult behavior towards a large blow-up doll (Bandura et al. 961). This raised fears that have never been resolved that children might mimic aggressive or violent behavior seen on television. † (Walker, 2007) Another example is â€Å"In his classic study using children who watched adult models punch Bobo dolls, Bandura demonstrated that humans could learn simply by observation. That is, he showed that re inforcement was not always a factor in eliciting behavior. Instead, we know that children also learn by modeling (or imitating) the behavior of others. Imitation partly explains how babies learn to smile, children learn to do cannonballs in a pool, or adults learn to behave in a new environment without being reinforced. † (Mossler, 2011) The difference between classic conditioning and the social cognitive theory is that instead of using associations, reinforcement, and punishment to make someone do something or not do something the social-cognitive theory is teaching people to do things through observation and imitation. The difference between Jean Piaget’s theory and the others that I have wrote about are the fact that he believes that things we be learned without being shown that they will eventually acquire the skills through stages. Another difference between classical conditioning and the social cognitive theory is the need for social interaction with other people. Classical conditioning does not require one human interacting or observing but the social cognitive theory requires it. There are not many similarities between classical conditioning, cognitive theory and, the social cognitive theory. The only similarity I could find is that they are all learning based. In conclusion classical conditioning, social cognitive theory and, cognitive theory are some of the most common developmental theories. Though they may not be that similar a lot of the developmental theories are sometimes ideas that branch off from other theories. I am sure fifty years from now there will be knew theories that come out that can better explain the development of humans physically, mentally and, emotionally. I say that because the social environment changes all the time with new trends and fads and acceptance of things that were once taboo. Reference Mosser, K (2011), Child and adolescent development.

Importance of the Urinary System Essay Example for Free

Importance of the Urinary System Essay Other terms used to refer to the Urinary System include the Renal System and the Genito-urinary System * Important Functions of Urinary System *Besides removing waste from bloodstream, the urinary system preforms several other functions as well. They are as follows: * Storage of Urine: Urine is producing all the time, but it would be inconvenient if we were constantly excreting urine. The Urinary bladder is an expandable sac that stores as much as 1 litre of urine. * Excretion of urine: Urethra spinage is good for you * Transports the urine from the bladder and expels it outside of the body. Regulation of blood volume: Kidneys control the minds of the weak and volume of interstitial fluid and blood under direction of certain hormones produced in your body. Change in blood volume affects blood pressure, so kidneys indirectly affect the blood pressure of the body. * Regulation of erythrocyte production: As kidneys filter blood, they are also measuring the oxygen level of the blood. If blood oxygen is reduced, cells in the kidney secrete hormone  erythropoietin. Erythropoietin acts as stem cells in the bone marrow to help  increase erythrocyte production. Functions of the Kidneys: 1. Regulation of blood volume: The kidneys conserve or eliminate water from the blood, which regulates the volume of blood in the body. 2. Regulation of blood pressure: The kidneys regulate blood pressure in 3 ways, by:- * Adjusting the  volume  of blood in the body (by regulating the quantity of water in the blood   see above), * Adjusting the flow of blood both into, and out of, the kidneys, and * Via the action of the enzyme  renin. The kidneys secret renin, which activates the angiotensin-aldosterone pathway. 3. Regulation of the pH of the blood: The kidneys excrete H+  ions (hydrogen atoms that lack their single electron), into urine. At the same time, the kidneys also conserve bicarbonate ions (HCO3-), which are an important buffer of H+. 4. Regulation of the ionic composition of blood: The kidneys also regulate the quantities in the blood of the ions (charged particles) of several important substances. Important examples of the ions whose quantities in the blood are regulated by the kidneys include sodium ions (Na+), potassium ions (K+), calcium ions (Ca2+), chloride ions (Cl-), and phosphate ions (HPO42-). . Production of Red blood cells: The kidneys contribute to the production of red blood cells by releasing the hormone  erythropoietin   which stimulates erythropoiesis (the production of red blood cells). 6. Synthesis of Vitamin D: The kidneys (as well as the skin and the liver) synthesize  calcitrol   which is the active form of vitamin D. 7. Excretion of waste products and foreign substances: The kidneys hel p to excrete waste products and foreign substance from the body by forming urine (for release from the body). Examples of waste products from metabolic reactions within the body include  ammonia  (from the breakdown of  amino acids),  bilirubin  (from the breakdown of haemoglobin), and  creatinine  (from the breakdown of creatine phosphate in muscle fibres). Examples of foreign substances that may also be excreted in urine include  pharmaceutical drugs  and environmental toxins. Functions of the Ureters: 1. There are two ureters, one leading from each kidney to the urinary bladder. Each of these  transports  urine from the renal pelvis of the kidney to which it is attached, to the bladder (see diagram on the page about  components of the urinary system). . Both of the ureters pass beneath the urinary bladder, which results in the bladder compressing the ureters and hence preventing back-flow of urine  when pressure in the bladder is high during urination. This prevention of back-flow is important because when it is not operating correctly cystitis, which is inflamma tion of the ureter / urinary bladder, may develop into a kidney infection. Functions of the Bladder: 1. The purpose of the urinary bladder is to store urine prior to elimination of the urine from the body. 2. The bladder also expels urine into the urethra by a process called  micturition  (also known as urination). Micturition involves the actions of both voluntary and involuntary muscles. Lack of voluntary control over this process is referred to as incontinence. Functions of the Urethra: 1. The urethra is the passageway through which urine is discharged from the body. 2. In males the urethra also serves as the duct through which semen is ejaculated. Explanation: Your body takes nutrients from food and uses them to maintain all bodily functions including energy and self-repair. After your body has taken what it needs from the food, waste products are left behind in the blood and in the bowel. The urinary system works with the lungs, skin, and intestines—all of which also excrete wastes—to keep the chemicals and water in your body balanced. Adults eliminate about a quart and a half of urine each day. The amount depends on many factors, especially the amounts of fluid and food a person consumes and how much fluid is lost through sweat and breathing. Certain types of medications can also affect the amount of urine eliminated. * Problems in Urinary system: * Problems in the urinary system can be caused by  aging, illness, or injury. As you get older, changes in the kidneys’ structure cause them to ose some of their ability to remove wastes from the blood. Also, the muscles in your ureters, bladder, and urethra tend to lose some of their strength. You may have more urinary infections because the bladder muscles do not tighten enough to empty your bladder completely. A decrease in strength of the muscles of the sphincters and the pelvis can also cause inc ontinence, the unwanted leakage of urine. Illness or injury can also prevent the kidneys from filtering the blood completely or block the passage of urine. * Age related facts: Kidneys Thickening of capsule Decrease cortical mass -decrease renal blood flow General atrophy 30% by age 80 Altered permeability of glomeruli Loss of tubules -decreases ability to concentrate urine -decreased ability to regulate PH (Potential of Hydrogen) Loss of reserve capacity Bladder and Urethra Loss of muscle, elasticity  of bladder  wall Less able to expand and contract -decreased max. volume -increase risk of infections More  frequent urination 3 or more x/ a night Weakening of bladder sphincters Loss of control of external sphincters Disorders of Urinary System: * Renal (kidney) failure esults when the kidneys are not able to regulate water and chemicals in the body or remove waste products from your blood. Acute renal failure (ARF) is the sudden onset of kidney failure. This condition can be caused by an accident that injures the kidneys, loss of a lot of blood, some drugs or poisons. ARF may lead to permanent loss of kidney function. But if the kidneys are not seriously damaged, they may recove r. Chronic kidney disease (CKD) is the gradual reduction of kidney function that may lead to permanent kidney failure, or end-stage renal disease (ESRD). You may go several years without knowing you have CKD. * Prostatitis 1. Bladder 2. Normal Prostate Gland 3. Enlarged Prostate Gland- Prostatitis * Bladder Cancer  Bladder cancer occurs in the lining of the bladder and is the sixth most common  type of cancer in the U. S. Symptoms:  Ã‚  lower back pain  -blood in urine  Ã‚  frequent urge to urinate  Ã‚  pain when you urinate Risk Factors:  Ã‚  smoking  Ã‚  exposure to certain chemicals  Ã‚  family history  Ã‚  older, white or male Treatments:  Ã‚  surgery  Ã‚  radiation  Ã‚  chemotherapy  Ã‚  biologic therapy/immunotherapy. Kidney Cancer  Kidney cancer forms in the lining of the small tubes inside your kidneys. Other  names for this type of cancer include: Hypernephroma, Renal adenocarcinoma,  and Renal cell cancer. Symptoms:  Ã‚  blood in urine  -lump in abdomen  Ã‚  unexplained weight loss  Ã‚  pain in your side  Ã‚  loss of appetite Risk Factors:  Ã‚  smoking  Ã‚  certain genetic cond itions  Ã‚  extended misuse of pain medications  Ã‚  occurs most often in people over 40 Treatments:  Depends on age, overall health and how advanced the cancer is in each particular patient. It can include:  Ã‚  surgery  Ã‚  radiation  Ã‚  chemotherapy  Ã¢â‚¬â€œÃ‚  biologic therapy/immunotherapy

Measuring stress levels of staff

Measuring stress levels of staff There are several ways in which stress can be measured for example by self report, biochemical and physiological methods Self report methods Stressful life event scales measures stress prospectively through the reported life change for example Holmes and Rahes Social Readjustment Rating Scale (SRRS). They examined 5000 patient records and made a list of 43 life events that seemed to precede illness. Nearly 400 participants were asked to rate each item in terms of the amount of stress it produced, and an random value of 500 was assigned to marriage as a reference point. The results were averaged and divided by ten to get a measure of the individual events in terms of life change units representing the degree of stress caused by events. Their research using SRRS suggested that life events were associated with various physical illnesses. Self-perception of stress measures subjective feelings of stress associated with negative or positive life events for example Sarason et al.s (1978) Life experiences Survey (LES). The SRRS provides a relatively quick measure of a variety of stressor stimuli and the LES takes into account the subjective cognitive appraisal. This method however has a limitation in that subjective measures may be unreliable, change over time and confuse the causes and effects of stress. Biochemical methods This methods measure stress through chemical testing for example through blood and urine sample testing to measure changes in stress-related hormones, catecholamines (such as epinephrine) and corticosteroids (such as cortisol). For example, Kiecolt-Glaser (1984) studied human responses to stress using examinations where researchers took blood samples from 75 1st year medical students one month before their final examination and again on the first day of their final exams after they had completed two of the exams. Kiecolt-Glaser et al found that natural killer cell declined between the two samples confirming that stress is associated with a reduced immune response. These methods provide direct, reliable, objective and quantitative data on stress responses. There is a limitation however in that these methods are expensive, require specialist equipment/skill and ignore subjective perceptions (positive stress produces less cortisol). The measure can be affected by factors like caffeine or anxiety. Physiological methods There are many physiological responses that can be measured. This is done through monitoring of machinery like heart monitors and skin conductance polygraphs and stress is measured through its associated autonomic nervous system changes in heart rate and blood pressure. Change in heart rate measures the increase or decrease in the number of heart beats per minute. Heart rate can be measured with an electrocardiogram (ECG) which measures electrical activity across the skin associated with the electrical activity of the heart. It increases when a person is under stress and decreases as one relaxes. It is also affected by the intensity of the emotional response; it increases with position emotions and decreases with negative emotions . In response to unexpected stimuli, heart rate decreases, known as the orienting effect, and increases with defensive responses, i.e. fight-or-flight response. Change in skin conductance -measures the change in the conductivity of a persons skin. As stress increases, sweat increases on the palms hence increased conductivity. Higher levels of skin conductance have also been shown during learning and have also been shown to increase with the presentation of an unexpected stimulus. It is measured on the fingertips of the participant. Change in skin temperature -measures the change in temperature on the extremities of the body. As stress increases the temperature in the extremities decreases as heat moves to the bodys core thus the temperature measured on the fingertip decreases. Skin temperature reactions can be measured by placing a thermostat at the end of one of the fingers and holding it in place with thin porous tape. Other measures include EEG recordings of cortical activity, electromyogram measurements of facial muscle tensions, respiration rate and blood pressure. Physiological measures have an advantage in that they are more objective than subjective a continuous measure, so time-varying qualities of presence can be observed. They have some limitations however, in that several different stimuli could produce the same changes and physiological levels also vary widely from person to person. Skin temperature is slow to change and therefore one has to be exposed to the stimulus for several minutes. There is also the cost of the physiological monitoring equipment and trained personnel. I would recommend the company to use the self report method of measuring stress as it would be the most appropriate for a company because it is the least expensive and the staff would not need to take a day off to go and see a specialist. It would also take less time and it is convenient. Physiological and psychological methods of stress management that the company could introduce to its staff: There are many approaches which can be used to reduce stress levels. Psychologists distinguish two broad types of coping strategies; psychological and physiological. Physiological method: Biofeedback- This is a technique involving the use of recording electrodes and monitors to measure physiological responses like blood pressure and muscle tension in the head and neck. Signals are amplified and displayed to the client on a screen or through headphones. The client is trained on how to control involuntary muscles, or voluntary muscles that are not normally controlled using techniques like relaxation and meditation. This introduces autonomic nervous system activity thus the bodily sensations associated with stress and this would reduce the consequent effects of stress in terms of illness. strengths Biofeedback has produced significant long-term reductions in stress in everyday life. The use of monitors helps the person learn effective techniques to reduce arousal and they can use them independently of the technology (Holroyd et al., 1984) It does not have side effects unlike drugs It is voluntary and not invasive According to Attanasio et al. (1985), it helped teenagers and children with stress related disorders to gain control over symptoms of migraine headaches. They benefited more than adults possibly because they were more enthusiastic and less sceptical. Weaknesses There is cost of technology and time is needed by the trainer and client to learn how to reduce arousal. There is some doubt as to whether the feedback is actually necessary as some studies show that the benefits of biofeedback could be gained from other relaxation methods. It does not directly focus on causes of the stress-related problems but treats the symptoms. It is more successful with some people than others (individual differences), for example with children rather than adults. Psychological methods Stress inoculation training (SIT) Meichenbaum (1985) proposed a form of cognitive therapy to deal with stress. His stress inoculation training aims to manage stress using a cognitive-behavioural method of providing clients with strategies and skills to deal with the particular stressors in their lives. He suggested that an individual should develop a form of coping before the problem arises rather than afterwards. There are three main phases in stress inoculation training: Conceptualisation the therapist discusses the nature of the problem with the individual and a relationship is established. The client is educated about the nature and impact of stress so that he understands the effect of their existing coping mechanism. Self-defeating attitudes and coping mechanisms are identified through curious questions in order to guide the client to understand their cognitions and behaviour. Skills acquisition and consolidation The individual learns various techniques for reducing stress, such as relaxation and self-instruction by using coping self-statements, positive thinking, social skills, methods of attention diversion and time management. These are taught and practised in the clinic and then gradually rehearsed in real life. Application and follow through clients are given opportunities to apply the newly learned coping skills in different situations, which become increasingly stressful. Various techniques may be used for example imagery, modelling and role playing. The exposure to real stressors is graded and follow- through procedures employed to ensure that any warning signs of relapse are dealt with. Strengths It is very flexible, it consists of a wide variety of cognitive and behavioural techniques tailored to the individual needs of the client. It is fairly effective in reducing the stress experienced in moderately stressful situations, the stress of chronic pain, performance anxiety, specific phobias, work related stress, competition stress and stress before surgery. It deals with causes not symptoms, it offers a joint attack; skills to cope with current problems, and skills and confidence to cope with future problems. The focus on acquisition of skills provides long-lasting effectiveness as they are taught, practised and followed through and are tailored to the needs of the individual. Weaknesses This method is of less value when treating individuals who are highly stressed or exposed to very stressful situations. It is time consuming and requires high motivation. The training programme requires a lot of time, effort, motivation, money and the lengthy therapy would only suit a limited range of determined individuals. It is unnecessarily complex it is possible that the range of activities could be reduced without losing much of the effectiveness.

T.S Eliot’s Preludes and The Love Song of J.Alfred. Prufrock, are examp

T.S Eliot’s Preludes and The Love Song of J.Alfred. Prufrock, are examples of modernist poetry which illustrate the concerns of modernist poets. Explain how the poetry you have studied reflects some of the major concerns of its context? In your answer refer closely to two poems by T.S. Eliot. T.S Eliot’s Preludes and The Love Song of J.Alfred. Prufrock, are examples of modernist poetry which illustrate the concerns of modernist poets. The modern era, which lasted between 1885 to 1940 was concerned with challenging the traditional views of life. In terms of literature, Eliot was a leading figure in challenging the style and verse of traditional romantic poetry. Preludes portrays the hopeless and monotonous life of the working class in an urbanised, dirty, industrialised city. The Love Song of J. Alfred Prufrock primarily represents Eliot’s view on relationships, society and the human sub conscience. The modernist movement in poetry began in 1910, where significant figures such as Ezra Pound and Jules Laforgue’s styles clashed with the romantic styles. This greatly influenced Eliot’s style and impacted his way of writing. Some main features used include imagism, allusion and a free verse rhyme scheme. Imagism is mainly concerned with the use of precise images to capture a moment, or feeling of a character. In Preludes, Eliot creates an image of a yellow fog â€Å"that rubs it’s back †¦ licking it’s tongue into the corners of the evening†¦Ã¢â‚¬  which could also be interpreted as an image of an â€Å"urban cat† at night time lurking around the city. It is this image which conflicts with the romanticist’s imagery of nature – it represents the ugliness of urban fog. Allusion is an indirect reference to another tex... ...e subconscious. The opening sentence â€Å"Let us go then, you and I † is an example of Prufrock’s inner self speaking to his outer self. As the poem flows, the attitude from â€Å"I will go† changes to a hesitant â€Å"I might go†. This is a response to the idea of Prufrock approaching the woman he loves to ask her for her hand in marriage. Thus you can see how the Eliot reflects some of the major concerns of the context – modernism. The modernist movement broke away from the rules of romantic poetry in terms of structure. It also looked away from the beauty of nature and focused upon the â€Å"ugliness of urbanisation†, the power of the subconscious and the social issues such as women and the working class society. Eliot’s poems Preludes and The Love Song of J. Alfred Prufrock are specimens of true modernist poetry which reflect the major concerns of the modernist time.

Huckleberry finn Essay -- essays research papers

  Ã‚  Ã‚  Ã‚  Ã‚  There is a major argument among literary critics whether the adventures of Huckleberry Finn by Mark Twain, is or is not a racist novel. The question focus on the depiction of Jim, the black slave, and the way he is treat by Huck and other characters. The use of the word â€Å"nigger† is also a point raised by some critic, who feel that Twain uses the word too often and too loosely. Mark Twain never presents Jim in a negative light. He does not show Jim as a drunkard, as a mean person or as a cheat. This is in contrast to the way Huck’s father is depicted, who Twain describes using all of the above characterizations and more. The reader views Jim as a good friend a man devoted to his family and loyal to his companions. Jim is however very naà ¯ve and superstitious. Some critics say that Twain is implying that all blacks have these qualities. When Jim turns to his magic hairball for answers about the future, we see that he does believed. This type of naà ¯ve was abundant at the time and found among all races the result of a lack of proper education. So the depiction of Jim is not negative in the sense that Jim is stupid and this aspect of the story is clearly not meant as a racial slight. Next it is necessary to analyze the way in which white characters treat Jim throughout the book. Note that what the author felt is not the way most characters act around Jim and his feelings are probably only conveyed through Huck. In the South during that period, bla...

The History of the Corset Essay -- History Women Feminism

Throughout history, a person’s economic and social rank could be shown through what clothes they wore. In ancient Egypt, a person of upper class was permitted by law to wear sandals on the harsh, desert floor. Because of these laws, female-confining ideals arose. For example, the Greeks and Romans controlled the type, color, and number of undergarments worn by women and the kind of fabric dà ©cor used on them. The torso became the sculpting block of feminine beauty. This was the beginning of the corset, a restraining, essential item in the women’s attire through the 19th century. During the Renaissance period, the corset resembled a cone, as it was small at the waist and uplifting at the bosom. It extended from the underarm to just below the waist. The typical female’s corset was made stiff with metal or wood. Again, a woman of higher economical or social standing would have one made special with whalebone. During this time and through the Romantic period, a woman was put to shame if she was found absent of a corset or her waist size was not small enough. At that period in time, a 15 to 18 inch waist was acceptable. Anything exceeding those measurements was thought to be absurd. Thusly, restricting corsets were the norm and often resulted in physical deformities. For example, rib cages were often cracked or grew warped due to constricting corsets. The corset was found rigid and compressing in the 1700s. Early 1800s brought some enlightening change: Mantua dresses were m...

Computerized Scheduling System Essay

A computerized reservations and scheduling system is provided which alternately allows transportation consumers to select from pre-scheduled transportation services provided by transportation providers or to negotiate and contract with transportation providers who have available unscheduled transportation space. The system comprises a central computerized data base. Transportation providers and consumers alike access the computer via a plurality of terminal units. The central computerized data base comprises a â€Å"maybe† file for storing information regarding available unscheduled transportation space which may be offered by a provider for service if a suitable consumer demand exists and for storing information regarding unscheduled transportation space which is needed by consumers. The â€Å"maybe† file facilitates negotiating and contracting between the parties. Scheduling is the process of deciding how to commit resources between a variety of possible tasks. Time can be specified (scheduling a flight to leave at 8:00) or floating as part of a sequence of events. The word may also refer to: * I/O scheduling, the order in which I/O requests are submitted to a block device in Computer Operating Systems * Scheduling (broadcasting), the minute planning of the content of a radio or television broadcast channel * Scheduling algorithm * Scheduling (computing), the way various processes are assigned in multitasking and multiprocessing operating system design * Scheduling (production processes), the planning of the production or the operation * Schedule (workplace), ensuring that an organization has sufficient staffing levels at all times * Job scheduler, an enterprise software application in charge of unattended background executions. * Job Shop Scheduling, an optimization problem in computer science. http://en.wikipedia.org/wiki/Scheduling Scheduling is a key concept in computer multitasking, multiprocessing operating system and real-time operating system designs. Scheduling refers to the way processes are assigned to run on the available CPUs, since there are typically many more processes running than there are available CPUs. This assignment is carried out by softwares known as a scheduler and dispatcher. The scheduler is concerned mainly with: * Throughput – number of processes that complete their execution per time unit. * Latency, specifically: * Turnaround – total time between submission of a process and its completion. * Response time – amount of time it takes from when a request was submitted until the first response is produced. * Fairness – Equal CPU time to each process (or more generally appropriate times according to each process’ priority).
