Explore the presentation of women in Much Ado nigh Nothing EssayExplore the presentation of women in Much Ado to the highest degree Nothing The women in the 1500s were alship canal expected to do things such as taking care of the family non working outside of their ho enforces and al elans seen as possessions, not volume. As in Shakespeares time they were seen not heard. Shakespeare used this as a theme in him novel, Much Ado about Nothing, and the character Hero in particular portrayed the normal wo domain. The typical woman was modest, convectional, reserved and many women were pressured to be exactly like her. There are many other ways of which women are presented in this 1599 play about love and the deception of appearances. The play was very popular with the audience and was a comedy. Women who had a high status were ordinarily linked with honour. Hero is an example of this as her father, Leonato, is a successful character and has high status. He is described as a, hon ourable father, which means that if she was to be, unfaithful, to Claudio then her alone family would go down in status and she Hero would be seen as an unclean creature now worth nothing.Heros overall presentation is a typical woman and is used as a fleck device to move the story along, so she is valuable but her value is not recognised. An example of this is when she furthers the plot when she is, unfaithful, to Claudio. Hero is a possession to be passed on from father to husband as the society was patriarchal and the women were dominated by men and were assets to bargain. In the spousal scene Hero hardly says anything in her defence, and what she does say are only in one line blocks, is my Lord well that he doth speak so wide? She is not saying that he is wrong, but just asking him to re appreciate what he is saying. This shows us that she is a typical, modest woman and cannot stand up for herself. When Hero is accused of being unfaithful to Claudio, her father doesnt defend h er like a typical father would do today, but he says, do not live Hero, do not ope thine eyes, Leonato is ashamed to be linked with his daughter and basically says that he wants her to die. This is not how women should be treated. They have no voice and people would believe a mans word over a womans.Hero is seen as a, plague right well prevented, which means she is no longer any use to Claudio and is a plague on him. Once women had lost there virginity to a man when they were not married, they were seen as useless and unclean, a woman would not be able to get a husband and would be put in a nunnery or kept indoors. Honour is linked to virginity because then the women were not vain and so that they could be married to someone of high status. Claudio thinks Heros appearance is deceiving him and he ruins her life as she had ruined his, thoughts of harm. He ruins her life because now people think that she is unfaithful, rotten orange, she will be worthless and kept indoors. Another exa mple of Hero as a typical Elizabethan woman is at the caller when she gets proposed to. Hero is told what to say to her marriage proposal and has no choice in what to say. Beatrice even prompts her on what her actions should be, speak cousin, or if you cannot, stop his mouth with a kiss. Womans sexual urge was controlled by men. Hero would be like any other good typical wife in Elizabethan times, she, would do any modest office. She is hush and chaste and conforms to the norms of the society. Hero is very predictable, again like the typical woman, now going to kiss Claudio, Beatrice prompts her on her actions. In contrast Benedicks and Beatrices relationship has more equality and they come across as comfortable with one another as they use, you , and, your, as apposed to, thee, and, thou, as Hero and Claudio use. Beatrice is presented in a very different way to Hero. Beatrice is presented very openly. All of her emotions are shown and she always says what she thinks, the commend ation is not in his wit, but in his villainy. This shows us that Beatrice is a very plotting and witty character who is in control of the situation. She is an independent woman, who was not like how women in Elizabethan times were presented, she was like Queen Elizabeth. Hero and Beatrice are complete enemys. Beatrice doesnt want any man to rule her life, in marriage, so takes an independent look to things. She doesnt want a husband because she wants to remain like she is, I had rather hear my dog barque at a crow than a man swear he loves me. Her strong voice is a strong comparison to Heros silence it makes them seen very opposite and is not the norms of Elizabethan society. Because Beatrice is so independent, she uses her wit to stop her from getting hurt, so I would not he should do me, my Lord, lest I should prove the mother of fools. It shows that Elizabethan women were quite vulnerable. The love that Benedick has for Beatrice is true love, this gives Beatrice the power to ma nipulate him, and she tells him to, kill Claudio, because she has to rely on a man to carry out what she wants to be done.The women in those times could not carry out a duel with someone else, as it was no, expected, of them to do that and they had to conform to the typical woman, like Hero. Beatrice shows her frustration when she says, O beau ideal that I were a man I would eat his heart in the market place, shes saying that if she was a man she would kill Claudio herself so makes Benedick chose if he looses a friend or love. Beatrice shows that she can be a domination person when she cuts Benedicks sentences short, Beat-, then she says, Princes and Counties Overall I think that the women in, Much Ado about Nothing, were pressured into being relieve, chaste and not seen, like Hero. Beatrice is the total opposite and has her own strong-willed, independent mind. Men and women were not treated as equals and men had so a great deal more power and freedom and saw the women as possess ions not wives. Hero resembles the perfect presentation of what a woman should be like. Beatrice does not because she is not quiet and is not told what to do, she is different, she is stubborn and will do things her own way.

A dramatic way EssayAfter the September 11, 2001 attack the civic line system of our nation was given a great deal of congressional attention. The Congress enacted the Aviation and sustaination Security Act (ATSA) on November 2001. The ATSA created the Transport Security Administration (TSA) within the Department of Transportation (DOT). The TSA was entrusted with the right of ensuring security in aviation as well as other modes of transport. This agency hire a number of people for the deployment of both passengers and baggage. Explosives detection equipment was used to check the baggage. The agency is also working on the Computer-Assisted Passenger Prescreening System (CAPPS) this would use field of study security as well as commercial databases in order to identify passengers who could pose risk for additional screening. TSA also initiated a number of programs and look on the use of technology and information in order to advance security. The Transportation Workers Identi fication Card program is issued to airport workers after a ambit check has been conducted on them. Biometric indicators have been incorporated in them so that each worker bottom be positively matched to his or her credential.Though TSA takes pains to bet that bombs and other threat items are non carried into the planes by the passengers on their self or in their baggage, areas such as the air warhead security, general aviation security and the airport perimeter security are still vulnerable, the air cargo is vulnerable as very(prenominal) little of the cargo on cargo and passenger planes are screened. Thus TSA has been advised to use a risk management approach to enhance and strengthen the air cargo security. Prior to September2001, screeners who were engage by the airlines very often failed to detect threat objects on passengers or in their carryon luggage.This could be because of insufficient training and a rapid turnover. In most of the airports the turnover exceeded 100 p ercent, the skilled and experienced screeners were few mainly because of low wages, few benefits and monotonous work. Moreover before September 2001 people entered the secure areas of airports, including the aircrafts as the limiting controls did not work as intended. TSAs first and foremost responsibility was according to ATSA that of ensuring security in all modes of transportation. The security screening responsibility was also shifted to TSA.Some of the aviation security responsibility such as security of air traffic control and other computer systems remained with FAA. TSA worked to establish itself and worked at meeting the deadlines set forth by ATSA. TSA had 13 employees in January 2002. A year later it had 65,000 employees. TSA had met over 30 deadlines during 2002 to improve the aviation security. Racial profile against the young muslim male seems an awful idea and therefore it ought to be abolished. all the same it is argued and even many minority police are of the opini on that it can be used as a statistical tool.It can be a cost effective way to tackle a certain enigma e. g. most people committing X belong to Texas, then if there is a reliable way to identify people from Texas, it would certainly reduce the action X. Still it is not ethical even though police argue that they are not taking action based on any race just that they are using race as a factor to identify suspects. This is discrimination by race and religion and when such discrimination meets approval, we start purport down the slope. Besides this the practical problems are also to be met. It certainly antagonizes the group that is being profiled.The young muslim men in America would not like it and might even flare up, and it might irritate them so that they who might have helped in a terrorist investigation might just shrug their shoulders now. Moreover how many people would it affect? Numerous? Muslim looking men hail from Nigerians to Iranians to Indonesians. The muslims of Cen tral Asia often resemble the Chinese and tree billet of Arab Americans are Christians. It is also to be noted that even if racial profiling isnt motivated by bigotry, over a period of time it is very likely to cause racial tension.The civilians would view all young Muslims males suspiciously, which would again inflame racial tensions. Therefore in order to preserve racial union an extra couple billion dollar get spent, for the security measure, it is still more worthwhile that creating disillusioned youngsters who in their anger might turn terrorists.Sourcescapital of Mississippi Brain A Aptitude For Destruction Organizational Learning in Terrorist Groups and its Implications for..

The Healthcare Delivery System Nursing Essay

The Healthc atomic number 18 Delivery System Nursing EssayWhat does it mean to be a attraction. According to Forbes Magazine, a draw is someone that isnt panicked to take the initiative to act. A leader is not only there during good times, but excessively in times of need and hardship. Whenever there are big changes that must take place, a leader is never afraid and instead depart look at this as an opportunity to improve the elder ways. There are many challenges a leader must face, especially in wellnesscare. Being ready and having contingency plans for every possible situation is what hindquarters set apart a leader from the rest.The Healthcare Delivery SystemThe health care delivery organisation or simply health system is a combination people, health care organizations, and all their resources that aim to deliver professional quality care to different target population (Hackbarth, 2009). According to the lend of Medicine (IOM) on their consensus report, the health care delivery system will need to achieve better performance on the following six dimensions to be improvedSafety Avoid doing harm to unhurrieds.Effectiveness Use of evidenced-base practice instead of unproven methods.Patient-centeredness Respect and involve perseverings in their care.Timeliness Treatment presumption without delays.Efficiency Maximizing results with lowest required resources.Equity Equality of all people in receiving health care.(Ameri abideProgress.org, 2008)The nurse leader discount use the preceding six dimensions defined by IOM as a guideline in times of change to reform the healthcare delivery system for the better.Leaders versus ManagersManagers can be leaders but not all leaders can be passenger cars. A person can become a leader establish on personality, knowledge, and expertise. A manager is often a position given by a higher authority. Since it is a position that is assigned, it is more stable darn being a leader is often only temporary. The main link up of a manager is the goal of the company or the organization. The leaders main concern is the satisfaction and goals of group members. A leader doesnt need to have a managerial position to be able to act as a leader. In contrast, a manager often requires leadership traits to function as a good manager (Finkelman, 2011).Transformational LeadershipThe idea behind transformational leadership is to create a leader that can easily adapt to changes and also empower the stave at the same time. This type of leader goes beyond just teaching staff of their role within the organization, but also able to influence others to be independent of their own thinking on how to further improve the organization to the consequence of even taking risks (Finkelman, 2011).The Institute of Medicine (IOM) recommends five core health care profession competencies to use as a framework to focus on improving care. They are as followsCare is focused on the patientCollaborate with other academic discipline s teamsUse of evidenced-based practiceImprove quality industryUse of informatics(Finkelman, 2011)With so many changes that need to take place on these five core health profession competencies to improve health care, a transformational leader will indeed be required since such a leader should have an easier time adapting to change. This leader will need to show exceptional(a) knowledge in these areas and be able to apply that knowledge on his practice while empowering others.Even a transformational leader has its flaws. If such a leader proves to be unsuccessful, it is usually due to one or more of the following errors miss of sense of urgency privation of a guiding coalescencyLack of a visionLack of communication about the visionLack of removals of barriers to the visionLack of systematic planningDeclaring a victory to soonLack of recognition of organization culture(Finkelman, 2011)There are different ways a transformational leader can overcome these errors. For the insufficienc y of sense of urgency, a leader needs to have a strong determination to complete the tasks required to finish the job in time. It doesnt matter how small a step must be taken as long as it leads to moving forward as soon as possible (Kotter, 2008). Lack of a guiding coalition can be resolved by acquiring more nurture that can be used to set the correct course of action. This can be done by the leader by gathering his team and discussing his findings and plans for the change. The leader should also prepare plans on how to handle communication barriers such as lack of vision, systematic planning, and communication. This plan can involve creating a focus group that will enable team members to voice their opinions and concerns as well as their achievements. This can also be an opportunity to share ideas on how to improve. Using questions that provoke honest answers that can also be used to evaluate how the team feels. No matter how sure a leader is, declaring a victory to soon should b e shunned upon. It might raise the morale of the people but the aftereffects of failure or loss will be a good deal more devastating compared to not declaring victory too early. A smart leader will be patient and will avoid making claims without backing it up. Finally, lack of recognition by the organization to its people or employees could cause feeling of un-appreciation-that no matter how overmuch hard a person work, his achievements will never be recognized. One way to solve this by the leader is to form some sort of yield system that will recognize employees that excelled in their field. This could be a monthly thing such as an employee of the month award or something especial standardised recognition award of how an employee excelled on something that benefited the organization. Whatever the case may be, its a good idea to reward employees that do well. This doesnt only keep their morale high but also makes them feel appreciated and important which often result in more pro ductivity at work (Entrepreneur.com, 2011).Competencies of an Effective LeaderThe dickens most important competencies I have selected for an effective leader are as followsWork in interdisciplinary teamsUtilizing InformaticsThe other competencies are also important but both of the above are increasingly becoming more so in our current and most likely future health care system. The health field is composed of several interdisciplinary sciences that each having their own expertise. A kind of leader that doesnt limit himself to one branch of health care and is willing to collaborate with other professionals is not only wise but puts the leader in a great advantage especially because of the information he can utilize in making good decisions. In my own opinion, being able to know where to get information on how to carry out what is intended is usually a better trait than trying to shoulder it all.Along with utilizing information is informatics-a field in science where information is p rocessed, managed, and retrieved mostly by the use of computers. An example of this is the Health Information Technology (HIT) that will be critical in implementing this system of managing health care delivery (RWJ Foundation, 2011). With the advancement in technology for the past 10 years, it will be unwise for any leader not to learn and take advantage of information technology. Even treat has a new field now called nursing informatics where nursing and computer science meets. Informatics has become relevant to nursing now more than ever. Almost every information known to man are now is being computerized and stored in big computer databases. Even in hospitals, from MARs to TARs, to patient records, discharge plans, care plans, etc. all are being automated and stored in computers. Hospitals everywhere and even other companies have a motto of issue paperless in the future. It will be obvious to any effective and competent nurse leader that learning informatics is a necessity (Sal sali, 2010).There was a study done in Ireland to find out leadership nurture needs. The study is done on nurses and midwives back in 2009 using a haphazard sample of over 2000 all across different departments and divisions. The purpose of the study is to describe the clinical leadership of these nurses. The leadership needs was measured using a questionnaire called CLAN-Q or Clinical Leadership Analysis of Need Questionnaire that was machinateed by the people conducting the research. According to CLAN-Q results, there are five main areas of clinical development needs for a leader and they are as followsManaging the clinical areaManaging patient careDeveloping oneself as an individualDeveloping the professionSkills for clinical leadershipObviously, a nurse leader needs to learn how to manage the clinical area. This can involve coordinating care and identifying care priorities. Being a patient advocate and protecting their privacy falls down to managing patient care. A nurse leader should also be aware of his/her limits by knowing his/her own strength and weaknesses developing into a better individual. Participating in professional gatherings or seminars relating to ones own profession can also further develop it. Lastly, empowering others and learning how to adapt to changes are necessary skills for a leader (Casey, 2012).I believe including the above five areas in manager and leadership development programs will prepare them better in becoming good managers and leaders.SummaryBeing a manager or a leader is not an easy task. not only there are so many things a manager or leader should learn, but also there are a attraction that they have to teach others. There are types of leaders that can be good in one department but not so much on others. There are also errors or mistakes a leader can make. But no matter what kind of leader or manager a person is, learning from past mistakes and pursuing for improvement are qualities not only ideal for leaders and manag ers, but also to an individual.

Adaptive Input And Output Devices

Adaptive Input And Output DevicesTechnology has been advancing and developing rapidly in the on-going era. The current era, overly known as the information era, retain involved in workers in the creation, distribution and the white plague of information. However, an adaptive and assistive subterfuge is in addition organism invented to aid the disabled in using the data processor. An assistive device understructure allow disabled tribe to accomplish daily living tasks, work, and education or recreation activities. It helps them enhance their quality of life and achieve greater independence. Assistive Technology devices give notice also improve physical and mental functioning, overcome a disorder and impairment, and strengthen a mental or physical weakness, aid people in improving their capacity to learn or even set back a missing limb.2.0 Adaptive input and output devicesAn adaptive device is a structure, instrument or equipment which bump offs life easier for people who h as a disability physically or mentally. It is a product which helps people who is not able to rehearse regular version of products. It is invented for people with physical disabilities such as limitation to vision, earshot or mobility. Adaptive technology helps with greater effectiveness for people with functional limits or incapacities by allowing them to complete tasks that they were not able or had great obstruction to complete. Adaptive Technology also provides divers(prenominal) methods of interacting with or enhancements in talk to the disabled. The personal information processing system (PC) can be the support of independence for lots of individuals with physical, sensational and learning disabilities.Many individuals with disabilities face several problems in terms of computer input, or using a computer for understanding documentation on the reminder and interpreting output. For the disabled, the keyboard, mo engage and monitor atomic number 18 the prime concern so adaptive and assistive software product and hardware have been invented to provide assistants. Screen commentator programs are created to allow a totally slur person to use the computer. These programs convert school text editions and icons into dialogue so one is able use a computer without the need to look at the monitor.PC access and accessible computer equipment aids can piss computer substance ab users easier to use word processing programs, enrapture e-mail, and surf the internet, but also able to aid non-computer users to handle more non-computer tasks. System which aids individuals who are not independent in verbal communication is known as an augmentative communication system. This system can include speech, sign language, gestures, synthesized speech, symbols, dedicated communication aids or microcomputers.Optical Character science (OCR)There are many types of devices which are available to aid the disabled people. They are optical character recognition (OCR), per meate reviewers, trackball and head wand or head stick. An Optical Character Recognition (OCR) is a software system which is used to scan printed or handwritten materials at electronic speed by simply scanning the form directly into the computer. OCR is able to scan word characters images through the scanner and then recognition engine of the OCR system interpret the images and function images of printed or handwritten word into ASCII (America Standard Code for Information Interchange) data. This device allows users to automate data captured from forms, eliminate keystrokes quickly to reduce data entry follow and still maintain the high level of accuracy bringd in forms processing applications.The Many Facets of OCRThe process of the OCR devices workThe Optical Character Recognition device replaces the monitor to aid the visual-impaired person. It has the ability to scan printed text or document and then speak it back in synthetic speech to the users or give up it to a computer. Screen ReaderThe screen contributors are software programs which provide speech or transcribe output. It allows a visually impaired person to establish text or words on the computer screen and identify icons on the Desktop or buttons which is graphic like on a toolbar. The user receives info from the computers sound card or the speech synthesizer.Screen readers are commonly employed by person who is blind or visually impaired.Screen reader also allows the user to navigate the computer using the keyboard instead of the mouse. Keyboard commands which are used by blind person are mostly the same commands a normal person can use on their computer. A special keyboard commands which provided by the screen reader is also used by blind persons. similarly listening to the information read by the screen reader, some people prefer using a refreshable transcribe display. A braille display is different from the computer screen. The Braille display is usually located close or below the keyboa rd. The screen reader sends information on the screen to the Braille display. Then, the user put his fingers on the display and read the information in Braille as it appears on the Braille display. Braille displays for useful to people who are desensitize and blind and people who work on a job which involve them to speak to clients on the phone or in a place which require people to remain silent like a library.A screen reader uses text to speech synthesizer to send information out active what is displaying on the screen as it is a memory resident program. Currently, system hooks is use to gain access to keyboard input, menu and dialog box messages on most Windows screen readers.The screen reader replaces the monitor as it is used by the blind people. A computer can be used without the use of the monitor with screen reader software that allows the screen display available as synthesized speech. Blind people usually use a screen reader to replace the monitor.Foot mouseA plunk mouse is a computer mouse which is used by a person who has physical disabilities with high-back, neck, throttle or no use in their upper arms. The foot mouse can be used to control the cursor through the computer software program to select text, icon and separate item in the same way as a normal hand mouse. Using a foot mouse can be slower, because most people have less accurate control movements with their legs and feet compare with their hands.Most foot mice have two segments. one(a) segment is used to control the cursor, while the other segment is used for mouse click or to select shortcuts. Most foot mice also have straps to help to sustain the device in position on the foot during use.http//www.disabled-world.com/artman/uploads/footmouse.jpgFoot mouse with programmable pedalThe pedal on the foot mouse with two-level devise avoid user from stepping on the incorrect button. These buttons do not only function the same as the hand mouse clicks, it also allow people to program their own customize shortcuts. In addition to people with arm, shoulder or hand difficulties such as stroke, arthritis or amputation, the foot mouse is also suitable for people with carpal tunnel syndrome.The traditional hand mouse can be replaced with foot mouse which allows user to operate the device by foot. It is an input device which is two-part with one foot navigating the cursor while the other controlling the mouse clicks and shortcuts. The cursor controller is just the same as a regular hand mouse.Refreshable Braille DisplayReading an electronic document using hands instead of eyes may be almost unrealizable for most people. However, it is possible for this to be done by using a Braille Display. A Braille display is a device that allows users to read text displayed on the computer screen. With this device, a person who is blind is able to navigate through the computers desktop, edit and create documents or browse the internet. Braille Display is also known as Braille Terminal. Usually, Braille display does not require to install a driver for it to function properly as in that respect arent many types of Braille display and screen readers is able to support most of this device. Once the device is enabled, the Braille Display will obtain the text that is currently highlighted on the display, the screen reader will then translate the text from the computer screen in Braille and the Braille Display will display the translated text on its built-in Braille cells.The Braille Displays use nylon pins or metal to make each cell of Braille dots on the device. Braille display is refreshable, this message when the user navigate to a specific line of text, the device shows the texts Braille corresponding and when the user navigates to another line, the device will automatically display the young text in the new line in Braille.Usually there are eight dots in each cell on a Braille Display. The six dots are for normal character of Braille while the two dots at the bo ttom are usually for denoting the cursor or highlighting texts.http//www.atarizona.com/media/BVI/BVIbraille7.jpgBraille display which is placed under the keyboard.The monitor can be replaced with Braille Display as monitors cannot be used or see by blind person. Braille Display can be a good assistive device for the blind people as this output device allows the user to read what is being display on the screen.Eye gaze pointing deviceThe eye gaze pointing device is an input device which can be used by people who are unable to use a normal hand or foot mouse, keyboard or a remote control. This device is mounted onto the computer and it is set focus on the users eye. This device consist of a camera which constantly scans one of the users eye and a sofware which analyses the picture taken by the camera to determine which part on the screen the user is looking at.Users are require to sit in front of the eye gaze pointing device with a specialized video camara mounted at the screen or mo nitor which observes one of the users eyes. Then the software which works together with the device will continually analyzes the image of the eye from the camera and determine where the user is looking on the screen. By looking at the keys or icon which are displayed on the screen. To make a selection with the eye gaze, the user stare or blink at the certain button, icon or other object on the screen which is equivalent to clicking it using a mouse.The mouse and keyboard replace with the eye gaze pointing device. Eye gaze pointing device is suitable for people who are unable to use a normal mouse or keyboard with the their hands.Braille EmbosserA Braille Embosser is an impact printer which translate text as Braille. This device makes Braille payoff more efficient and cost effective as it employs a special translation software to print a printed document.Blind users normally call traditional printers as ink printers to differentiate them from their Braille counterpart. Like ink prin ters, braille embossers also have all shape and size and are used by personal computer users to large organisations which requires fast, high-volume embossing capabilities.Braille Embosser usually works like a printer. However, instead of create a text document, this device prints Braille text. Braille Embossers usually requires a special braille paper which is thicker and more costly compare to a normal paper. Some embossers which are high-end are capable of printing on normal paper. Braille Embossers can be one-sided or two sided which can determine the speed of embossing characters per second.The computer monitor can be replaced with this Braille Embosser for the blind people. This is because by using this output device, it allows a blind person to be able to read what is being display from the computer. However, the cost may be expensive.3.0 Green ComputingGreen Computing refers to environmentally sustainable computing. It describes the use of resources in computing efficiently . It is related to the study, manufacturing, design, use and disposal of computers or other related products or devices such as monitors, printers, servers and network systems among others. The motive of green computing is similar to green chemistry. Green computing is practise to reduce the environmental impact of computing industry.Green computing has become very important as the impact of greenhouse gas production has on global heating and climate change. A number of manufacturers have begun improving the performance in environmental of their organisation, services and products in an effort to reduce their environmental footmark.Computers and their peripheral devices use a considerable amount of exponent and contain hazardous materials. However, it is easy to reduce the environment impact. There are many ways which can make a computer more eco-friendly and minimize the environmental impact.Use the power management settings whether it is under hibernation, sleep or standby mode. A computer has power management settings which enable it to sleep or standby automatically after certain period of inactivity. It is easy to enable these options through the control panel and can save up on electricity bill. Also disable the screensavers as running it can increase energy consumption as it may preventive the monitor from being in standby when idle. By disabling a screensaver, the monitor can be switched off without wasting any electricity.Computer manufacturers are also practicing in minimizing the environmental impact by developing greener computers. Computer manufacturers like HP is practising few steps to green computing, they are developing a sustainable green computing plan which includes recycling policies, recommendations for disposal of used peripheral. Discard unwanted device in an environmental responsible way. Computers have pollutants that can release harmful substance into the environment. Never throw away computers to the landfill. Contribute working computers to a non-profit agency. This manufacturer also reduces paper consumption as there are many easy ways to do so.Computer manufacturers like ASUS also doing something to develop greener computer to minimize environmental impact. The Green ASUS philosophy comes in because the manufacturer believes in applying an eco-friendly way towards every aspect of their business. This manufacturer produced the worlds first motherboard which is lead-free and halogen-free and the first full-HD monitor which is halogen-free. It is the first notebook manufacturer to receive the EU Flower Eco certificates and EPD and the first among other computer manufacturers to obtain the Japan Eco Mark. ASUS was being known at the 2011 ENERGY STAR Award Ceremony for its Energy businesslike Product Design.ASUS technologies are constantly being developed and improved with the main objective of environmental preservation. This manufacturer design products that are easy to recycle, reuse and fragment and gre ener manufacturing processes which are halogen-free and lead-free.4.0 ConclusionAdaptive and assistive devices are very important for disabled people to use computer efficiently and productively despite the cost of the device. These technologies have made people around the globe to use the computer productively.Green computer is very important for computer manufacturers, users and organisation to be aware(predicate) as protecting and minimizing environmental impact can prevent from global warming and also able to save cost from electricity.

Effect of Phototherapy on Sleep Disorders

Effect of Phototherapy on Sleep DisordersIn the natural world, the vindicated dark cycle entrains our rhythm. Light is a very effective Zeitgeber. In the presences of environmental time cues, sopor- stimulate physiology, and gene expression continue to demo a near-24-hour circadian rhythm regulated by the Suprachiasmatic marrow in the Hypothalamus. Phototherapy is an accepted modality for non- pharmacological management of Circadian Disorders much(prenominal) as Delayed Sleep soma Syndrome, Insomnia etc. This review discusses the physiological principle and gamey falls evidence based literature of phototherapy and its management in Sleep Disorders.IntroductionLiving organisms exhibit a biologic periodicity, this rhythm when occurs on a 24 hour cycle is known as Circadian bicycle.A rhythmic biological cycle that displays an endogenous entrainable oscillation of less than 24 hours in known as ultradian rhythm. and that last for more than 24 hours is known as Infradian rhythms .Circadian trolls throw rhythmic cycling of sleep patterns, food intake, sexual demeanour, core body temperature and secretion release of hormones such as ACTH, Prolactin, Gonadotorophin and Melatonin.Circadian Rhythms atomic number 18 generated by the Suprachiasmatic Nucleus (SCN) of the Anterobasal Hypothalamus. Pineal gland regulates the rhythmic production and release of melatonin. The duration, phase and amplitude of melatonin and cortisol secretion, are influenced by changes in light-dark cycles. The plasma levels are low during day time and are high at night. This rhythm is maintained by the SCN and is entrained by the light-dark cycle. Low light intensities like 100 to 500 lux similarly have been shown to suppressed levels of melatonin.Phototherapy or light therapy utilizes light boxes which are typically LED square silver lights, ranging from 8-12 x 12-24 inches that emit 10,000 Lux (highest Lux) light, cool food colouring temperature light acts as natural sunlight without the harmful effect of UV rays. This mode of entraining the sleep wake cycle is an accepted modality and mainstay interposition in the non-pharmacotherpeutic management of Circadian Rhythm Disorders.Principles of PhototherapyThe goal of the Circadian Rhythm is to maintain a bridge between sleep patterns and the internal clock that is set(p) at a optimally synchronized time. This results in a normal sleep-wake pattern.The Biological Model-Phase response curveThe Phase Response curve is modulated by two efficacious modalities i.e. light and melatonin, both of which are exploited to entrain the circadian cycle. Bright light is very helpful in synchronizing the compassionate rhythms and the melatonin serves as a dark pulse helping to induce night-time behaviors. Bright morning light advances circadian rhythms bright as a new penny(predicate) evening light delays them. Melatonin in the evening advances circadian rhythms melatonin in the morning delays them.Circadian Disturba nces and Insulin ResistanceType 2 Diabetes Mellitus is a multifactorial disorder, of which Circadian Disturbances is one of the lifestyle factors that contribute to it. Sleepdisturbances including sleep insufficiency, sleep loss, sleep fragmentation, are connected to abnormal Glucose Metabolism and thus, increase the risk of Type 2 Diabetes Mellitus. Studies in rodent models suggest that disruption of Circadian Rhythms leads to impaired glucose homeostasis and beta-cell failure, culminating in increased susceptibility to Type 2DM. Disturbed Circadian Rhythm is causative factor in the recent epidemic Obesity. In controlled clinical studies, acute 1-3 week circadian misalignment (alone) or in combination with sleep restriction results in dysregulation of glucose homeostasis and consequent glucose intolerance attributed in part to loss of beta-cell bit as well as decline in insulin sensitivity.CIRCADIAN RHYTHM PROBLEM CONTRIBUTES TO INFLAMMATORY DISEASES.Inflammatory bowel infirmit y (IBD), including ulcerative colitis (UC) and Crohns disease (CD), is a chronic and recurrent insurgent disorder of the intestinal tract. Study says that sleep disturbances are one of the main reasons of pathogenesis of the patients with IBD. In addition melatonin plays a alert role in regulation of inflammation as well as tolerant system and antioxidant system in the intestinal disorders. (16, 17)CIRCADIAN RHYTHM and optically ImpairedBright light has been shown to suppress Melatonin secretion even in visually impaired subjects which substantiates the fact that non-visual photoreceptors in the eye mediate the Circadian Rhythm regulating effects of lightCIRCADIAN RHYTHM AND IMMUNITYSleep restriction and sleep deficit increase your vulnerability to disease. The immune system is connected to the sleep regulatory system and actions of the immune system to fight disease.Sleep is regulated partly by immune system components called cytokines. Blood counts of T-cells and levels of pro inflammatory cytokines are high during the night while leukocytes and the anti-inflammatory cytokine IL-10 go up during daytime.Changes in the immune system seem associated with the onset of narcolepsy, which has a neurological cause (brain cell death) inflammatory diseases increase cytokine levels and make large number feel fatigued. This is a good thing during a short-term injury or illness, as it drives the person to rest. For those with chronic inflammation, however, the immune system keeps them tired for long periods, which may explain symptoms of fibromyalgia and chronic fatigue disorder. The trouble in sleeping that people with those conditions experience is not due to beneficial the discomforts of the illnesses, but because the sleep regulation system is affected.The different phases of sleep are responsible for different functions within our bodies. The first and second phases involve settling in, resulting in rhythmic breathing and a rejected body temperature. The third and fourth stages are when our bodies are working to restore themselves. During this time our muscles relax and the blood add going to them increases. Our bodies use this time to repair tissue damage and grow new tissue. Important hormones are released and our energy is renewed. These stages appear to be a tiny factor in maintaining a healthy immune system and any sleep disturbance that impacts them, impacts our health. It is becoming increasingly evident that disruption of daily rhythms, such as from sleep deprivation, affects the immune response.Toll-like receptor 9 (TLR9), is an immune system protein that can sense bacterial and viral DNARole of PhototherapyCognitive have-to doe withLight intensity has a direct impact on cognitive performance and alertness and on the subjective feeling of sleepiness. The researchers found that volunteers subjected to higher light intensity during the afternoon were more alert all the way into the early evening than those who were not. But whe n subjected to light intensity 10 times weaker, they showed signs of sleepiness and obtained lower scores on the memory tests.Artificial light is used to phase shift circadian rhythm and help improve performance, sleep, and well-being during shiftwork simulations , this was proven in study designed for NASA personals during t he prelaunch week. The treated subjects were self exposed to 10, 000 Lux. The treated personnel showed a positive result reporting go against sleep, performance, and somatic and emotional well-being than control subjects and rated the treatment as highly effective for promoting compensatement to their work schedules for the study. Nocturnal alertness, performance, and daytime sleep could be improved by light vulnerability of tolerable intensity and duration in a real work place. This was proved in a cross-over design study conducted on 12 night Shift nurses with three different treatment procedures Room Light (RL) exposure in the night followed by a 1hr sun light or 10,000 lux light next morning(0830 to 0930), Bright Light (BL) a 4-hour nocturnal light exposure of 4,000-6,000 lux (from 0100 to 0500) and Bright Light with Sunglasses (BL/S) the similar nocturnal light exposure as in BL was done with light attenuation in the morning. Nocturnal alertness was measured by a visual analog scale. Daytime sleep was recorded with actigraphy. Nocturnal alertness was the highest in the BL/S. The improvement was maximized by attenuating morning light.Sun-Downing phenomenonSundowning is a clinical phenomenon characterized by the emergence or increment of neuropsychiatric symptoms such as confusion, disorientation, anxiety, agitation, aggression, pacing, wandering, resistance to redirect screaming, yelling and so forth observed late afternoon, evening or at night and occurs among cognitively impaired, demented, or institutionalized elderly patients. In a 6-week, double-blind, placebo-controlled, cross-over trial the effects of bright light therapy c ombined with melatonin on motor restless behavior in demented patients had been evaluated. This study concluded that bright light therapy (10,000 lux bright light) has a positive effect on motor restlessness in subjects with dementia. snappishness disturbancesManic-Depressive Illness (MDP) MDP is recurrent illness in which episodes of Mania and Depression occur and remit spontaneously. Several clinical studies say that disturbance in the Circadian Rhythms play a crucial role in its pathophysiology. Melatonin secretion shows abnormal levels in some bipolar patients (MDP). Patients with MDP exhibit circadian sleep wake rhythm in which patients spent one complete sleepless night in between two nights of normal sleep. In a study, 143 patients with a study depressive episode in the course of bipolar disorder (DSM-IV criteria) treatment with 3 consecutive totalsleepdeprivation cycle (each composed of a period of 36 hours awake followed by recovery sleep), light therapy, and lithium rapid ly decreased the depressive suicidality and prompt antidepressant response in patients with drug-resistant major depression in the course of bipolar disorder. border personality disorder (BPD) is typically characterized by instability and impaired behaviour, affectivity, interpersonal relations and lifestyle. This open study assessed 13 female patients for the effectiveness of the application of bright light (10,000 lux, 630 to 730 a.m. for 6 weeks) added to SSRIs in drug-resistant depressed patients with comorbid BPD who did not show any improvement to 6-week administration of antidepressants. The participants were regularly evaluated employ the CGI, HAMD and MADRS scales and the BDI and BDI self-report inventories. All the assessments proved that the application of Bright light leads to a significant improvement.SAD Phototherapy acts through Retinal Melatonin or Rhodopsin, which regulates Dopamine release in the eye where it acts as the main neurotransmitter. The retina-SCNvpine al gland forms a link, which is disturbed in SAD. By suppressing retinal Melatonin, Phototherapy has been suggested to correct the underlying biochemical abnormality seen in SAD and thereby inducing clinical remission.In Non- Demented people, light therapy is an accepted and validated treatment for seasonal affective disorder, but has also been reported to be effective in Non Seasonal Depression (15).Recently it has been noted that exposure of SAD patients to natural sunlight in the morning hours resulted in complete remission of depressive symptoms. In the study, N=24(12 SAD patients and 12 controls) were exposed to morning light therapy in the winter and the melatonin profiles being sensitive to light were measured before and after treatment. The SAD Patients showed a phase advance of melatonin rhythms in response to phototherapy which showed an association between phase position and phase shift in the SAD patients. This instability may be secondary to impaired serotoninergic func tion in the afferent pathways to the suprachiasmatic nuclei. This seems to be a significant advancement in the etiology of SAD that links light with Mood Disorders. In Seasonal Affective Disorder (SAD) is common when vitamin D stores are typically low. wavelengths between 280-320 nm which are Broad-spectrum light therapy that allow the skin to pee vitamin D. In a prospective, randomised controlled trial was conducted N=15 subjects with SAD (8 subjects-100,000 I.U. of vitamin D and 7 subjectsphototherapy).At the onset of treatment and after 1 month of therapy subjects different depression scale were administered. Vitamin D status improved in both groups (74% vitamin D group, p ADHDMorning bright light therapy is associated helps shrink both subjective and objective measures of core ADHD pathology, improves mood symptoms, and phase advance in circadian appreciation. Multiple regressions showed that the shift toward an earlier circadian preference with LT was the strongest predict or of improvement on both subjective and objective ADHD measures.In the ElderlyThe risk of developing depression increases with old age. The occurrence of a major depressive episode in Alzheimers disease is as high as 20-25%and minor depressive symptoms occur in an additional 20-30% (9, 10).In a randomized double-blind placebo-controlled trial, patients with early Alzheimers Disease (AD), Mild Cognitive Impairment (MCI) and Subjective Memory Complaints (SMC)(N=79, Age = between 50 75). Patients were exposed to 10,000 lux for two years, the fighting(a) condition or 300 lux in the placebo condition, daily, for two half-hour sessions at fixed times in the morning and evening. Neuropsychological, behavioural, physiological and endocrine measures are assessed at baseline and follow-up every five to six months. The evaluation showed long-term daily bright light prevented worsening of sleep-wake rhythms and depressive symptoms in elderly people with memory complaints. Elderly experience increased difficulties with sleeping, and thus could be one of the contributing factor for mood problems.(11)Factors contributing in age processAging processImpaired Ocular light transmission due to age related eye deficienciesRequires high demand of light intensities inorder to maintain a decent input to SCNDiminished SCN inputArrhythmia in the Sleep Wake cycleStudies report that it is possible to reactivate the SCN and improve Sleep Wake Rhythm by applying extra light. Light therapy provides a safe treatment option (13).Its reported that, bright light therapy is decreasing common health issues (14). In 10 Alzheimers patients with sundowning behavior and sleep disturbances were studied for a week who received 2 hours/day of exposure to bright light between 700 p.m. and 900 p.m. The results showed that the proportion of total daily activity occurring during the nighttime decreased during the light-treatment week. The relative amplitude of the circadian locomotor activity rhythm, a measure of its stability, increased during the light-treatment week. This diversity of effect mediated through a chronobiological mechanism.Artificial light is used to phase shift circadian rhythm and help improve performance, sleep, and well-being during shiftwork simulations , this was proved in study designed for NASA personals during t he prelaunch week. The treated subjects were self exposed to 10, 000 Lux. The treated personnel showed a positive result reporting better sleep, performance, and physical and emotional well-being than control subjects and rated the treatment as highly effective for promoting adjustment to their work schedules for the study.In study bright light exposure improved sleep quality in 7-18% subjects, the study consisted of 13 interventional studies with 1154 participants.Jet lag causes distress to the number of travelers impairing sleep, mood and cognitive performance. Timed exposure to bright light and melatonin administration can help to reduce symp toms. Specific recommendations using bright light and melatonin for eastward and westward travel before and after handout are provided for time zone changes of up to 6, 79 and 10 or more hours. Timed bright light and melatonin administration, by helping to adjust underlying circadian rhythms to the new time zone, can serve to mitigate the symptoms of jet lag. Reducingthe symptoms of jet lag by this methods can lessen the mood, cognitive and behavioral symptoms resulting from these desynchronized rhythms.(

birth order Essay -- essays research papers

Birth OrderOne long controversy among behavioral scientist is the existence of a sib coiffe effect. Birth order research and theories can be criticized because of differences between parents, sib positions of the parents, size of families, socioeconomic status, and culture. The conclusions drawn from research studies on sibling position are also often contradictory. However for some reason children with certain birth order roles grow into adolescents and adults with similar qualities.In order to understand the sibling positions in a certain family the family system must be understood, since elements of structure in family systems form the context in which sibling positions develop. The family environment includes membership units, interaction patterns, boundaries, rules, roles, and alliances. The desires, hopes, and dreams of the parents are carried by the first child. Everything the child does is being done by the first time in the eyes of the new parents. The landmarks of the first smile, tooth, steps, word, first sidereal day of school, graduation are all met with overjoyed responses from parents, grandparents, and an early(a)(prenominal) relatives. In most families, the responses from this large family audience are more exaggerated than they will be for any subsequent child. The first children are assigned functional roles as they enter the family system, which include the job assignment, interpersonal responsibilities, and kindly interactions. (Hoopes & Harper, 1987). Parents believe that the extended family and their environment spotter what the first child does to determine what they are like as a family. Therefore, the main message that first children receive is that they are on display and that the family snap is outward. Leading children to believe that they are the central focus and their actions have consequences beyond them. First children have a sense that their behavior and words are weighed by others and then adopt external validation to evaluate themselves. Despite the familys high expectations for all of their children, the performance of the first child is emphasized more than any other child will be. For interacting this steering first-born children learn that their job assignment is to produce outcomes that meet with the familys approval. First children may wo... ...y exhibit marked independency or extreme independence. Since the child has been reared alone in an adult world, the only child is very often extremely anxious to please others, especially parents and other adults. The only child has a youth period, which is free of the puzzling problem of sibling rivalry. This makes the only child extremely confident with is comes to completing task rise and receiving the approval of others as well as very critical of themselves. (Falbo, 1984).Placement in the family has a lot to do with a persons way of thinking and relating. While many other factors help shape a childs personality first-borns do things fast er then other siblings and undertake like more seriously. Second-born children tend to be more laid back in achievement since the parents are less available. Third-born children have many privileges and gains considerable social skills because of interactions with older siblings. While only children, in their own category, are self-confident and have a great sense of responsibility. Birth order, like every other factor in the development of the child, can and will differ from the norm for individual children. Each child is absolutely unique.

Statistical Handling Data Coursework on High School Students Essay

Statistical Handling Data Coursework High SchoolFor this handling statistical data coursework I provide be investigating the high and weights of students of years 7 to 11 in High School. Although this is a fictitious school the data is based on a real school. I will look for a trend in the heights and weights of the students to see if the taller they are, the much they weigh. This is my hypothesis. My Null hypothesis is that there is no correlation between height and weight, and my alternative hypothesis is that there is strong, positive correlation between them. I will because investigate the heights of boys in years 7 and compare them to the girls, and then do the same in year 11. I will then be able to compare these two sets of results. These are my second and third hypotheses.I am carrying this investigation turn out because from my hypothesis I want to know whether students in the older years should be separated from the younger students in the eat queues. This could be necessary because if the taller students are heavier, then the shorter ones will get hurt in the queue to lunch since students usually push their way to the front. So if the taller students are the older ones, then the year groups should be separated in the queue in order to prevent anyone getting hurt. In order to carry out this investigation, I will need to collect the heights and weights of all the students in High School between and including years 7 to 11. Instead of collecting the data, I can find the information on an exam board website. This data is reliable because it is provided by the exam board and is based on real students, however, it whitethorn be unreliable because it is secondary data, not primary since I am not physically collectin... ...rect guesses. They also provided a lot of inappropriate data such as their names which is inappropriate since isnt worth investigating.The data could be biased because it was only collected from one school and not from other areas in the country. The data may be biased because there may have been a lot of snack shops or fast food restaurants near the school, which may have affected the students weights. I could have investigated further by using more than one schools data and compared them and I could have had more hypothesise. This would have given more precise results due to a larger range and a larger sample.I could have drawn more graphs and do more calculations to get more accurate results. For example I could have calculated the standard deviation for my three hypothesise to get a more accurate spread of data than the interquartile range.
