Computers and Society essays

Computers and Society essays In "Africa Goes Online," Daniel Akst and Mike Jensen discuss the potential of the Internet in combating the "information famine" in Africa. In a country where there are little resources to spare for social services, virtual universities could bring learning to millions at a fraction of the cost of traditional schools. Educated residents in these countries would have a larger, global outlet to market their skills and services. The authors cite several case studies as examples of this potential. In Dakar, Senegal, for example, video link-ups allow medical students to study under a group of physicians from Brussels. Secondary students from Namibia are working on a website to showcase the important African entomological collections in the country's National Museum. An organization called SchoolNet Africa is teaching basic technology skills to children around the continent. Poverty and lack of infrastructure are significant problems, but activists are optimistic about their efforts. Much of the networks in Africa rely on technology like e-mail and newsgroups, though a growing number are using video and web technology. These networks allow people to exchange information about their services and their products or simply to keep in tough. A distant village in Uganda that only receives snail mail every few weeks, for example, now has a communal computer station that receives e-mail for every resident. More importantly, these technologies also have the potential to reach children in far-flung schools. By helping to ensure that the next generation of African children is technologically skilled, computers have much potential One thing that struck me about this article is the similarities and differences between Internet users in Westernized and African countries. ...

Temporal Lobes in the Cerebral Cortex

Temporal Lobes in the Cerebral Cortex Temporal Lobes The temporal lobes are one of the four main lobes or regions of the cerebral cortex. They are located in the largest division of the brain known as the forebrain (prosencephalon). As with the three other brain lobes (frontal,  occipital, and parietal), there is one temporal lobe located in each brain hemisphere. The temporal lobes play an important role in organizing sensory input, auditory perception, language and speech production, as well as memory association and formation. Structures of the limbic system, including the olfactory cortex, amygdala, and the hippocampus are located within the temporal lobes. Damage to this area of the brain can result in problems with memory, understanding language, and maintaining emotional control. Function The temporal lobes are involved in several functions of the body including: Auditory PerceptionMemorySpeechLanguage ComprehensionEmotional ResponsesVisual PerceptionFacial Recognition Limbic system structures of the temporal lobe are responsible for regulating many of our emotions, as well as forming and processing memories. The amygdala controls many of the autonomic responses associated with fear. It regulates our fight or flight response, as well as helps us develop a healthy sense of fear through fear conditioning. The amygdala receives sensory information from the thalamus and other areas of the cerebral cortex.  In addition, the olfactory cortex is located in the temporal lobe. As such, the temporal lobes are involved in organizing and processing sensory information. Another limbic system structure, the hippocampus, aids in memory formation and connecting our emotions and senses, such as smell and sound, to memories. The temporal lobe aids in auditory processing and the perception of sound. They are also vital to language comprehension and speech. An area of the brain called Wernickes Area is found in the temporal lobes. This area helps us to process words and understand spoken language. Location Directionally, the temporal lobes are anterior to the occipital lobes and inferior to the frontal lobes and parietal lobes. A  large deep groove known as the Fissure of Sylvius separates the parietal and temporal lobes. Temporal Lobes: Damage Damage to the temporal lobes can present a number of issues. Damage resulting from a stroke or seizure can produce an inability to understand language or to speak properly. An individual may have difficulty hearing or perceiving sound. Temporal lobe damage may also result in the development of anxiety disorders, impaired memory formation, aggressive behavior, and hallucinations. In some cases, patients may even develop a condition called Capgras Delusion,  which is the belief that people, often loved ones, are not who they appear to be.

Mental Health Promotion Project Essay Example | Topics and Well Written Essays - 1500 words

Mental Health Promotion Project - Essay Example This definition does not focus on the mere absence of illness or disease; but also on the presence of wellness on multiple factors. This concept is in opposition to the way in which many clinicians view the concept of health. Often the emphasis is on the absence of symptoms of illness; and medical professionals forget to attend to the presence of wellness. While this may or may not be as significant with illnesses of a purely physical nature; such a narrow perspective may not be adequate when dealing with problems that affect mental health. While House (2002) and Seeker (2005) claim that focusing on the symptoms and pathology helps keep a focus on resolution of symptoms and encourages a curer's approach; it needs to be mentioned that a person who is diagnosed and receiving help may be feeling better in part due to the fact that he or she is experiencing being cared for as against someone who is not receiving care. Squire (2002) has noted that someone who does not share the competenci es with the rest of the population could be termed as unhealthy; something that is rather unfair. A better definition is that of the Health Education Authority (HEA) (1997) which includes emotional and spiritual resilience. This is the factor that allows one to enjoy the experience of life and cope with pain (Squire, 2002; Jeanette, 2009). We may say that the WHO (2004) definition that mental health is a state of wellbeing is a more positive definition that focuses on the ability to cope with normal stressors and the ability to work in a fruitful and productive manner and to contribute to the society around them. Promoting Mental Health. Barry and Jenkins (2007) have found that a focus of developing mental health has helped in reducing the number of people diagnosed with mental disorders. It also has the positive impact of increasing the number who recover (Friedli, 2009). Promoting mental health can thus be defined as â€Å"Any action to enhance the mental well-being of individual s, families, organizations or communities (DH 2001).† The national service framework of 1999 has established certain standards of care that are designed to enhance the recovery experience of patients. Over time, the focus has been on not only reducing the extent and number of symptoms seen; but also on the growth of a wellness principle. This principle is one that guides the treatment and carer actions such that the emphasis is on overall recovery and health. Most policies for health care are aimed at the working population. This has many reasons; from the density of this population; to the contribution they make towards the running of the significant services, including the health services. The working population is also the population which contains the parents of minors – a population whose overall wellbeing is to some extent contingent on the wellbeing of the adults who influence their lives. Any country functions best when its working population is well and functio nal in that they participate in meaningful activities and have healthy relationships with people and elements of their lives. The ‘Quality Framework for mental health promotion (Health Education Authority, 1997) was put in place in order to ensure that mental health promotion projects are effectively planned, consistently delivered and properly evaluated.

Impressionist Artists Essay Example | Topics and Well Written Essays - 750 words

Impressionist Artists - Essay Example The essay "Impressionist Artists" discovers the artists of impressionism. Their works display the use of short brush strokes and unmixed colors which are commonly observed in impressionist artworks. Compared to the romantic art, the impressionists, as the word implies, used general impressions of their subjects to show their expression of the art as opposed to the traditional, photographic means of painting. One of the works of Camille Pissarro is his painting entitled Church and Farm at Eragny, completed in 1890. This pictures a farm with cattle grazing among the grasses near the trees. There is a couple walking towards the church located behind the trees and bushes, partially shown, with the steeple as the dominant figure that makes it recognizable as a church. Near the church, behind the trees, are houses which suggest the homes of the farm owners. Behind the houses is portrayed a cloudy sky which generally give other colors used in contrast to the dark and gloomy colors used in t he painting. Pissarro used thin, short strokes to give a general impression of the picture of his artwork’s title, the farm and church at Eragny. This consequently gives vague images. The lines are not well defined as to give more details to the images captured in the painting rather just gives an idea of what they really are. For instance, the carabaos and horses do not show details of their horns or other parts so that they may difficult to determine what kind of cattle they are. The short brush strokes used to give the impressions.

David Hume - Naturalistic Metaethics, Politics, and Psychology :: Philosophy David Hume

David Hume - Naturalistic Metaethics, Politics, and Psychology ABSTRACT: According to the views expressed in this paper, influences unrelated to the conclusions of Immanuel Kant and G. E. Moore respecting what they saw as the appropriate foundation for moral systems seems to have been at work in the reactions of both to the earlier criticisms of David Hume. Building on a "recent meeting" with Hume in a pub on Princes Street in Edinburgh, I develop the suggestion that both Kant and Moore were loyal to traditional notions of an intuited, non-prudential basis for ethical injunctions. Kant, by his insistence that any morality linked only to hypothetical imperatives cannot be truly "moral," and Moore by his refusal to see the emptiness of his posited "good as simply good" which he felt must be kept free of any corrupting reference to real-world prudential constituents, thus support the foundation of ethical systems in an inner, unanalyzable moral impulse. And they do so in obedience to commitments that antedate their moral philosophies. I also claim that Hume has been misunderstood in that he did not mean to oppose the naturalistic grounding of moral systems in his famous statement disjoining is-statements from ought-statements; what he really intended was to point out the illogic of moralists who improperly pretend to derive categorical or intuited moral imperatives from real-world is-statements while denying any prudentiality or a posteriority to the transaction. Because both maintain that this simple inner moral impulse must be independent of prudential considerations in making moral decisions and judgments, Kant and Moore oppose naturalistic ethical systems which, like J.S. Mill's, suggest that this-worldly welfare and happiness are in large part coexistent with the true meaning of morality. Their position, therefore, places both of these proponents of intuitionist metaethics at odds with the principle of political social democrats that a respectable moral system must place worldly satisfactions and happiness above obedienc e to any putative "higher" moral law and its intuited imperatives. I had a talk with David Hume one rainy night recently in a pub in Edinburgh, over—naturally—kippers with brown bread and a pint of stout or two. He let me in on a secret and gave me leave to whisper it in turn to a few friends. Which is why I jotted down this account of our meeting and am presenting it to you here. Remember what that great analyst wrote to set in motion the train of thought that culminated in G.

Nurse: Health Care Field Essay

The health care field has numerous amounts of individuals that care for patients or assist with their care. All persons that assists with a patients care must be able to communicate effectively amongst each other and this includes the nurse. Nursing is a communicative intervention and is founded on effective communication. Nurses have to communicate with various people such as: patients, families, physicians, and or consultants to provide the best care for his or her patients. So communication is the most important aspect when it comes to caring properly for patients. Communication is the simple element of human relations that allows people to establish, maintain and improve interactions with others. â€Å"Communication is essential when reporting a patient’s status, change in condition, or developing and revising the plan of care† (Fernandez, Johnson, & Jones, 2010, pg. 266). Furthermore, the importance of effective communication includes an interdisciplinary team approach which in turn promotes safe and effective health care for the patient. All health care professionals share a mutual commitment to serve the patient and work towards optimal health care for the patient. This is carried out by using the interdisciplinary approach of health care. Interdisciplinary team is defined, â€Å"as a group of health care professionals from diverse fields work in a coordinated fashion toward a common goal for the patient† (Saunders, 2013, pg. 60). This makes each team member valuable, and when each team member’s expertise and perspective is brought together patient care is improved and delivered in a more complete and effective manner. The facility at work at uses the interdisciplinary care approach when we receive trauma patients. These trauma patients can range from motor vehicle collision, shooting victims, or any incidents involving life threatening injuries. Each member of the trauma team has a title or a role within the team such as: team leader, manager, or facilitator. For example, the emergency room resident is in charge of the neurology assessment and airway, the trauma resident and trauma attending are responsible for the rest of the assessment. We also have a primary nurse that records all events that take place in the trauma room. Another member is the intensive care nurse, she delivers all the meds and any other skill that are needed for the patient. We also have a phlebotomist, chaplin, and respiratory therapist on the team. Other doctors are also available if other injuries such as: broken bones, neurologic conditions, or cardiac conditions arise. All the members of this team, brings valuable professional safe care to the trauma patient promoting optimal outcomes. â€Å"Ineffective communication is a leading cause of preventable patient injuries and deaths† (Fernandez, Johnson, & Jones, 2010, pg. 265). If all the members of the health care team are not communicating effectively it can jeopardize the care of the patient and also exhaust the interdisciplinary team. This is why communication is very important when providing care for patients. Another approach to health care is the intradisciplinary approach. The intradisciplinary approach is an individual that works alone to promote health in patients. An example of this is a home healthcare nurse. The home health care nurse provides care for a patient in his or her home. This nurse works alone when caring for patients. This professional nurse has to be organized and able to make decision on his or her own regarding the patients care. I feel the home health care nurse must be very knowledgeable is his or her field and have keen assessment skills. This nurse should have experience within the hospital before deciding to care for others at their home. This difference with interdisciplinary care is that the nurse has multiple resources at the time of care for the patient. caring for Finally, working as a team in the health care field helps empower not only the nurse, but also the patient. â€Å"Empowerment is a transactional process involving relationship with others. This relationship includes mutually beneficial sharing through mutual sharing of knowledge, resources, and opportunities; and respect for self and others† (Burkhardt & Nathaniel, 2008, pg. 72). This develops the professional nurse to provide successful, safe care for his or her patients. When patients witness nurses and physicians working together to assist with his or her health care. This in turn enables and may motivate the patient to â€Å"develop awareness of area that need change, foster a desire to take action, and share resources, skills, and opportunities that support change† (Burkhardt & Nathaniel, 2008, pg. 471) in his or her health . The nurses and patients experience and perspective regarding healthcare empowers them to make change patient to become advocates in their health.

Ryan Khaghani Mr. Schaefer Honors English 10B, Period 8 6 March 2017 Security Versus Privacy The Internet was first used in the nineteen sixties by a small group of technology professionals. Since then the internet has become an essential part of today’s world, from communicating through texts and emails to banking, studying, and shopping, the internet has touched every aspect of our lives. With the growing use of the internet, protecting important information has become a must. While some believe they have the right to privacy, and feel that the government should not be at the center of their lives. Others feel that the Internet has evolved into a weapon for our enemies, and believe the government must take action by proactively†¦show more content†¦They don’t believe in any government intervention, especially if it invades their right to privacy. Some may say it is equivalent to asking â€Å"all citizens to carry location tracking devices — [because] it would make tracing criminal acts much easier† (Wu). Many people in today s soci ety would object to this solution, not because they wish to commit a crime, but because they feel it is interfering with their day to day lives. A large portion of Americans are extremely worried about the government interfering with their life: â€Å"52% describe themselves as ‘very concerned’ or ‘somewhat concerned’ about government surveillance of Americans’ data and electronic communications† (Bertrand). Many feel they are experiencing life like citizens of Oceania in George Orwell s novel 1984. The fact that we are surrounded by new technology, â€Å"combined with a [more involved] government has caused dramatic changes† which further supports this concern (Wu). That change the behaviour of the users to be extremely cautious on the internet, fearing one is being watched. To many, the increase of surveillance is worrisome, and they feel it intrudes on their constitutional right that protects them from unnecessary searches, an d seizures. Although some citizens fear the fact they are constantly being monitored, many
