You have probably noticed this effect a number of times. If you have ever stared for a long time at a fixed point and then suddenly shifted your gaze somewhere else, then you probably noticed a brief afterimage effect in which you continued to see the original stimulus. Learn more about what afterimages are and why they happen. Types of Afterimages There are two major types of afterimages: positive afterimages and negative afterimages. In some instances, the colors of the original stimulus are retained. This is known as a positive afterimage. In other cases, the colors may be reversed. This is known as a negative afterimage.?? There are a number of situations that can increase the likelihood of experiencing an afterimage: Brief exposure to a very bright stimulus, particularly when the surrounding conditions are much darker than the stimulus. Glancing at the bright midday sun or the glare of bright headlights at night are two instances that might produce this type of afterimage. This brief exposure to an intense source often produces a positive afterimage.Prolonged exposure to a colored stimulus, even if the surrounding conditions are equally well-lit. Staring at an image in a book for 60 seconds or so before turning to stare at a blank, light-colored wall can produce this type of afterimage. This prolonged exposure to a colored stimulus often results in a negative afterimage. Positive Afterimages In a positive afterimage, the colors of the original image are maintained. Essentially, the afterimage looks the same as the original image. You can experience a positive afterimage yourself by staring at a very brightly lit scene for a period of time and then closing your eyes. For the briefest of moments, you will continue to see the original scene in the same colors and brightness. The exact mechanisms behind positive afterimages are not well understood, although researchers believe that the phenomenon might be related to retinal inertia.?? The original image stimulates nerve impulses, and these impulses continue for a small window of time after you close your eyes or look away from the scene. The cells in the retina take some time to respond to light, and once the cells have been excited it takes some time for that response to cease. While positive afterimages happen quite frequently, we are generally unaware of them because they are so brief, often lasting as little as 500 milliseconds.?? Negative Afterimages In a negative afterimage, the colors you see are inverted from the original image. For example, if you stare for a long time at a red image, you will see a green afterimage. The appearance of negative afterimages can be explained by the opponent-process theory of color vision.?? How exactly does this process work? You can see an example of how the opponent-process works by trying the following activity. Draw an image of a red shamrock outlined in blue on a white piece of paper. Stare at the image for about one minute before shifting your gaze immediately to a white sheet of paper or a blank screen. After staring at the shamrock, you probably experienced a green and yellow afterimage for a very brief moment of time. According to the opponent-process theory of color vision, staring at the original red and blue image involved using the red and blue parts of the opponent-process cells.?? After that minute of extended staring, the ability of these cells to fire action potential was exhausted. In other words, you briefly wore out those red-blue cells. When you shifted your focus to a blank, white screen, those cells were still unable to fire and only the green/yellow opponent-process cells continued to fire action potentials. Since the light reflecting off your screen could only activate those green and yellow cells, you experienced a brief afterimage in green and yellow rather than in red and blue. You can also see an example of negative afterimages at work in an interesting visual illusion in the negative photo illusion. In this illusion, your brain and visual system essentially create a negative of an already negative image, resulting in a realistic, full-color afterimage. A Word From Verywell Afterimages can be an interesting visual phenomenon to observe. They can also be an important tool for helping researchers better understand how color vision and the visual perceptual system work.

Cyber Bullying And Its Effect On Society - 883 Words

Cyber-bullying is the use of electronic communications to bully a person. Cyber-bullying takes place by using the Internet, cell phones, video game systems, and other technology.

The Stanford Prison Experiment Essay - 1207 Words

Anthony Westcott English 252-Instructor Levine Writing Assignment 2 October 26, 2015 The Stanford Prison Experiment During the summer of 1973 an experiment of the psychology of imprisonment was conducted by psychologist Philip K. Zimbardo. Zimbardo created his own jail in the basement in the Stanford University psychology building. Every participant had to be mentally and physically fit in order to participate in this experiment. Participants were randomly split into two groups’, guards and prisoners. Participants who were selected to be prisoners were arrested, blindfolded and sent the Stanford prison. The prisoners had to strip down and put on a prisoner uniform. The guards had to have a uniform also. Their uniform was composed of silver reflective sunglasses, handcuffs, whistles, billy clubs, and keys to all the cells and main gate. Prisoners had no freedom, rights, independence and privacy. Guards had social power and the responsibility of managing the prisoner’s lives. The day of the experiment everyone fell into their roles of guards and prisoners . The next day the prisoners started to rebel which motivated the guards to take affirmative action against the prisoners and maintain law and order. By the last days of the experiment the guards became sadistically aggressive and the prisoners became and passive.

There’d many reasons as too what causes the earthquakes and how they started. The earthquakes in California are caused by movements of huge blocks of the earth’s crust known as the Pacific and North American plates. â€Å"The Pacific Plate is moving in the North West direction and is scraping pass North America at a rate of two Inches a year. About two-thirds of this movement occurs on the San Andrea Fault and some parallel faults- the San Action, Elisions, and Imperial faults† (â€Å"Southern California Earthquakes And Faults†, n. . ). Over time, these faults minor earthquakes. Let’s talk about plate tectonics. There six major plates and they are named after the continents that they are embedded in, such as North America, Africa, and Antarctic. The plates make out the outer shell of the earth called the lithosphere. â€Å"One way a mountain is formed is through convergent boundaries which is when plates serving land masses collide, the crust crumbles and buckles into mountain ranges† (â€Å"Plate Tectonics†, 1996-2014).

Introducing Electronic Queue Management †Myassignmenthelp.Com

Question: Discuss About The Management System Royal Melbourne Hospital? Answer: Introduction The Royal Melbourne Hospital (RMH) like other facilities across Australia running outpatient clinics usually find it difficult dealing with long patient queues and the confusion that comes with it. Patients are also concerned with the long waiting time at the reception and at the waiting bay. There is thus need for a solution and as a recommendation in this presentation; the facility should install a digital electronic queue management system at both its RMH City Campus and RMH Royal Park Campus outpatient clinics. This presentation thus involves the description of the system, best practices using the technology, related barriers and enablers of the project, methodology for choosing participants in related focus groups and further, the ethical considerations in rolling out the project. Problem Description According to the management and the workers at the Royal Melbourne Hospital, long patient waiting time at the outpatient section has become a serious concern. A thorough research established that there are different factors that contribute to the long waiting menace at the RMHs outpatient clinics. These include first, long queues at different reception desks and waiting rooms that are very crowded. Secondly incorrect details of patients in the facilitys administration that then needs clarification and challenges in pronouncing patient name by clinic staff also increase waiting time. A number of patients have continuously also raised concerns over their privacy in regard to name-calling at the waiting bays within the outpatient unit. Further, where clinical staff members have been unaware whether a patient had already checked in or whether they are ready to be served, the confusion has ever been leading to clarifications that are a waste of time. Best Practice Recommendation Best practice requires that hospitals develop strategies which can accelerate the flow of clients/patients at crowded units especially in outpatient clinics and improve service integration. It also provides practical approaches which can be used to reduce the wait times at the clinic. One of the most effective methods to solve this particular problem is to use a self-check-in and electronic calling system (Ibanez et al, 2015). Since this system is specifically for hospitals, it will enable patients to automatically check in without queuing at the outpatient reception. The patients can also leave the waiting bay and reduce the usual congestion but called back remotely before their appointments. The system will also be important in facilitating the capturing and verification of individual patients data automatically. Research indicates that queue management systems allow hospitals to create a criterion for improving services ((Ibanez et al, 2015). Since calling of patients will be done automatically, the system captures both call and complete time stamps for reference. The facility can then evaluate their performance in regard to the maximum time a patient needs to take at a particular section. This can also inform decision making on the need to improve service speed among healthcare workers (Xie, 2013). The system will capture the arrival time of each patient, their call, time taken for consultation and in-clinic wait time. Hospitals using the electronic queue system which I also recommend for the RMH, have reported shorter and/or no queues at outpatient reception desks. They have also reported reduced crowding at the waiting rooms with staff giving a positive feedback. It helps solve the patient name pronunciation problem and provides a visual display of the flow of patients within the outpatient unit. Automation of queuing management increases the workers rate of compliance with maximum time for patient call and completion during consultations (Xie, 2013). Statistically, the system is reported to be able to thus reduce the wait time at clinics to below 20 minutes for each patient. As a result, I highly recommend the installation of the electronic queue management system at the ABCD hospitals outpatient care unit in order to solve the problem of long waits for patients. Enablers Barriers Among the enablers should first be that the facility will serve patients with posters indicating how the electronic queue management system works. Secondly, the workers are likely to be willing to embrace the technology understanding well that it will reduce their work burden. Further, it is also easy and logical to have assistant to direct those patients who might not be aware of how the system works and those with disabilities. In terms of barriers, it will take some time for both patients and workers to get used to using the electronic system. Secondly, the system is relatively expensive and needs a technician to run maintenance procedures often for quality functionality. The RMH will thus have to incur costs for training its staff and clientele on the use of the technology through focus groups. Focus Groups There are different factors that must be considered when selecting participants in focus groups in the clinical setting for low risk projects like putting up an electronic queue management system. Institutions which intend to embrace the electronic queue management technology should first use focus groups to train workers and clients visiting the facility on the technology. Effective focus groups need to have between 6 and 10 participants (Redmond Curtis, 2009). While the outpatient clientele should participate on a voluntary basis, healthcare providers within the facility should all take part in the focus groups. There should however be separate focus groups; one for the volunteering clients and others involving healthcare providers within the hospital. Focus groups in hospital setting can include representatives from different departments that will be directly affected by the operations and data captured by the electronic queue management system (Zwaanswij Dulmen, 2014). The diff erent focus groups should have facilitators and observers to run the discussion and training on the use of the technology. Effective focus groups should usually not take more than an hours time. Separating the two groups including healthcare workers and outpatient clients is crucial in preventing unexpected conflicts and/or power struggles. The facilitators should however make the ground neutral in that shy participants are not intimidated by those that are more assertive. The moderators should be experts in the technology and skilled in handling groups. The venues chosen according to the Nonprofit Business Advisor Journal (2016) should also be appropriate as the environment influences responses and reactions to the conversation especially for the groups that involves outpatient clients. It is paramount to ensure that participants who form the outpatient clientele must have an informed consent before being included in the focus group (Anderson, 2011). While the focus group for health workers at the facility may be held a few times , there is need for repeated focus group sessions with other volunteers who would like to give their views on the technology even after implementa tion is on-going. This will be crucial in informing decision on making necessary improvements at the outpatient section of the hospital. Ethical Considerations in Participating in Focus Groups Using the Technology First, tension is likely to emerge if health workers at the outpatient section are put in the same focus groups due to the obvious imbalance of power and potential power struggle (Item 12 of Part C). The facilitators should thus separate focus for healthcare providers from those involving volunteer patients. Secondly considering that majority of Australians speak English, any patient who does not understand English including the deaf and blind will always be assisted by an assistant who will be regular at the reception (item 14 of Part C). Their bookings on the digital electronic queue management system will be done by the assistant who can show them when to get into any room once the system calls out their numbers. Thirdly in line with item 13 of Part C, the focus groups should only involve adult volunteers mainly above 18 years (Anderson, 2011). However, parents who are willing to bring their children who are not below 16 years to take part in the focus group under their watch will be free to do so. Considering section 3 part B of the ethics form, this project can involve children but not those aged 16 years and below. They can however, only be included in focus group discussion with parental consent (Moore Richardson, 2013). As indicated earlier, the focus group will not include the deaf and the blind since it is basically includes audio sounds and a visual display. Further in line with item 3 Part B Section 3 on participant vulnerability, those with impaired ability to consent will be assisted to book their place on the queue by an assistant. Even so, parents and or people with the responsibility to give consent on their behalf can be asked to take part in the focus group and/or use the ele ctronic queue management system. Conclusion The presentation above involves the description an electronic queue management system recommended for the RMH hospitals RMH City Campus and RMH Royal Park Campus outpatient clinics. The presentation cites best practice aspects of the technology in reducing waiting time in health facilities. It also includes related barriers and enablers of the project implementation and the methodology for choosing participants in focus groups to discuss its use and importance. Further, the ethical considerations in rolling out the project have also been outlined to ensure that it meets the threshold of a low-risk project.

North Korean Nuclearisation

Introduction Nuclearisation has in reality become a significant political matter in the world for the past ten years. This has concurrently been marked by the nuclearisation of North Korea, United States, South Asia, Iran, India, Libya and many other states.Advertising We will write a custom essay sample on North Korean Nuclearisation specifically for you for only $16.05 $11/page Learn More North Korea’s interest in nuclear weapons capacity has long aggravated heated arguments between policy makers and researchers. Such arguments are mostly about the reasons for engagement and repeated dissatisfaction in attempts to confer to Korean denuclearization. These debates widely reveal divergent opinions of the North Korean government and its sustainability as an independent political, financial and martial system. They also reflect the likely consequences of prolonged nuclear development in this secluded and highly eccentric state (Sidney, 2007). Efforts to hold back North Korea’s interest in nuclear weapons is among the topmost running and least victorious sagas in global security. It is however highly unfortunate that North Korea keeps on deceiving the international community through its open attitudes and mischief. This is in contrast to the advancement in international nuclear disbarment and non- proliferation. The subject of North Korean nuclearisation has been deteriorating over time. This essay will assess North Korea’s venerable quest for nuclear weapons and its potential insinuations for national security. It will establish whether North Korea is a responsible nuclear weapon state in comparison with other states. Discussion North Korea is not a responsible nuclear weapons state.

North Korea’s irresponsibility in this case is seen when it continues working against international laws and requirements while at the same time declining to abandon its nuclear drives. Not only did it not take part in these encouraging developments but also acted as a key impediment to the global community’s efforts to create a world that is nuclear weapons free. North Korea’s irresponsibility as a nuclear weapons state is also seen when it goes against the individual rights of people. It is one of the countries whose people are mistreated by denying the citizens rights to choose their own ways of living. Although North Korea claims that their nuclear weapons are not instruments for assaulting and threatening others, they use them to offset aggression and attacks from the other countries. For instance, North Korea states that their nuclear deterrents can in no way be abandoned and should further be made stronger. United States further asserts that it would at no point recognize North Korea as a nuclear weapon country. It argues that North Korea present path is a â€Å"dead end â€Å". It has developed nuclear weapons for its own benefits, safeguarding its sovereignty and existence rights. The irresponsibility of North Korea as a nuclear weapons state has further been confirmed. It is irresponsible and ethically repugnant for any nation to produce and own weapons for arbitrarily killing billions of people. For instance, on March 2010, North Koreas torpedo led to the sinking of the ROK naval craft Cheonan. This assailment claimed 46 blameless lives (Nathan Daniel, 2009).Advertising We will write a custom essay sample on North Korean Nuclearisation specifically for you for only $ 16.05 $11/page Learn More India is the most responsible nuclear weapons state compared to North Korea, Pakistan, Iran and other nuclear weapons. It has taken significant efforts to establish the export legislations for nuclear weapons. This has been taken as unexpected progress to lessen war threats in these country something North Korea has not even thought of. North Korea keeps proclaiming that it would make reliable efforts for denuclearization which has so far remained doubtful among other states. Conclusion The Possession of nuclear weapons by North Korea has augmented the stakes in disagreements. It has also threatened victims on an incredible scale. North Korea should thus discard its nuclear weapons programme and pursue the example of other countries such as India and Libya. The present trends in worldwide politics towards conflicts and wars must be abandoned in preference for dialogue and conformity with international law. Engaging in dialogue just for the sa ke is North Korea’s long preferred approach for holding up denuclerisation.This must not be contemplated any longer. North Korea must demonstrate honesty of its words by taking actual and irreversible steps towards denuclearization. The Korean government is however taking some approaches to minimize the use of nuclear weapons. These approaches include a no nuclear North Korea, two track approach and the approach of grand bargain. The two track approach emphasizes that North Korea should not be simply rewarded for going back to dialogue after performing provocative deeds. It first needs to demonstrate a strong commitment to denuclearization and take tangible steps regarding that end (Alagappa, 2009).Advertising Looking for essay on international relations?
