Health And Safety Issues Of Immersive Virtual Reality Technologies Essays

Health And Safety Issues Of Immersive Virtual Reality Technologies Essays Health And Safety Issues Of Immersive Virtual Reality Technologies Paper Health And Safety Issues Of Immersive Virtual Reality Technologies Paper Gupta, Wantland and Klien (1996) propose that many of the peripheral equipments used in VR are possible fomites. A fomite is a safe object that is capable to harbour pathogenic organisms and as such, may work as an agent for the transmission of infectivity. They then propose that airborne pathogens and skin flora flourish in atmospheres as similar to those of HMDs and hand controller devices. An added thought at this point is that HMDs are frequently of enclosed design and produce a substantial heat in powering the displays. This can regularly lead to some sweating for the user particularly if the immersive task needs a definite amount of physical activity. Immersion Injuries Both Gupta et al. (1996) and Viirre (1993) propose that there may also be a chance of injury while the user is using a fully immersive HMD. As Viirre proposes, when a user is using an HMD, they are operationally blind in actual terms. This can cause problems due to conflict with real world objects or probably the VR system cabling and even if the user has some external vision, the forceful immersive scene may divert attention from the real world. Additional, many HMDs also offer sound cues for the user that effectively reduce aural stimulation from the real world. Physiological Physiological problems are probably the most well documented and at present, well researched sickness problem recently credited to VR systems. In fact some accounted physiological side-effects such as simulator sickness have been studied for some time. Of the probable physiological side-effects, visual symptoms and motion sickness type symptoms emerge to cause the most concern. As a result, majority of the studies into physiological results has been focussed in these areas. Visual Issues The visual presentation of the virtual atmosphere is very significant. The processing and organisation of visual input engages the use of a larger portion of the brain than for any other sense. North (1993) approximated that for a complicated task such as driving, 90 per cent of the received information is visual. It is therefore not astonishing that producers go to great lengths to offer a compelling visual atmosphere. As proposed however, stereoscopic semi-immersive systems may have added side-effects. One of the prime causes for the origin of side-effects is proposed to be the dissociation of accommodation and union in the visual system. Indication of Near Market Development In 1993, Mon-Williams, Wann and Rushton accounted physiological symptoms in many subjects pursued by immersion in an HMD. Of the 20 subjects who contributed in their experiment, 12 complained of symptoms such as headache, eyestrain and nausea and 4 displayed a transient decrease in binocular visual acuity. The subjects also displayed symptoms of binocular stress that included modifications in heterophoria and an increment in near point of junction. Mon-Williams and Pascal (1995) proposed that these symptoms of visual/binocular stress were connected, not only to poor image quality and close working distance of the screens, but more primarily with the inconsistency between space and convergence requirement when using a stereoscopic HMD. This problem will take place in any stereoscopic system where the main image is shaped on a flat screen and stereo images are presented by demonstrating slightly dissimilar images to each eye. In the natural atmosphere, focus and union are essentially connected. If one accommodates (focuses) on a near object, the eyes will automatically unite. Likewise, if focus is transformed to a distant object, the eyes will mechanically deviate slightly (see Figure 1). Using stereoscopic display devices such as shutter glasses or HMDs, this will not happen. In this situation, the focal demand is always invariable but the convergence demand modifies as the user regards objects at different geometric depths in the virtual world. This accommodation/ convergence is not a natural occurrence and has been said to result in visual stress. Probable Health Benefits Mutually Howarth (1994) and Wilson (1996) point out that in addition to looking for problems; it is significant to make out that VR methods may also attest helpful in various applications. Recently there is much investigation work being carried out in the VR field that will be of benefit to users. In terms of physical issues, more usual interface methods may reduce static posture problems, the use of LCD displays may minimise vision problems associated with CRT displays and physical loads associated with keying (Wilson, 1996). VR also presents a much improved method for health and safety training, even though as Howarth (1994) proposes, this function is largely concealed. VR methods can be used in ergonomic assessment of workspace plan, for fast prototyping of control interfaces, for the simulation of probably dangerous surroundings such as nuclear plant maintenance and in education and training of users in parts such as the maintenance of complicated machinery. As Howarth says, the fact that the use of VR has helped an operator avoid an accident or react correctly in the event of a crisis is largely unseen. VR also has numerous applications that can be directly linked to healthcare. In a white paper on the usage of Virtual Surroundings for Health Care, Moline (1995) shows numerous parts where patient care can be assisted by VR methods. These include:  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The use of VR for remote telesurgery.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   VR methods used in local surgery such as endoscopy, where the surgeon manipulates instruments by viewing a TV monitor.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   VEs used as surgical simulators or trainers.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   VEs used as therapy devices to reduce anxiety or fear. One example is dentists using 3D eyeglasses to divert a patients attentiveness during dental operations  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   VEs are also being used to reduce phobias such as agoraphobia and vertigo. North, North and Coble (1996) present an indication of existing work in the use of VR methods to decrease phobias in their book VR Therapy. Conclusion Investigation into the side effects of VR use is a complicated and difficult business and it is clear that concerns do remain about the outcomes of using such systems. Educational investigation does show that some indications happen whilst using VR tools and that these outcomes (such as nausea) can be quite incapacitating in the interim. Whether or not there is a lasting outcome is difficult to find out, partly because of the fact that VR methods are comparatively new and are constantly evolving. References Bolas, M.T. (1994).

Human Wisdom and Advertisements Essay Example | Topics and Well Written Essays - 750 words

Human Wisdom and Advertisements - Essay Example Advertisers are sophists. In any given advertisement, the main aim is to convince the buyer that the product is perfect in order for the buyer to buy it. Instead of most advertisers to advertise a product on the basis of the truth, most of them use persuasive tactics. Sophistic advertisements include power point presentations on TV, Web sites content which contain three-dimensional photographs of the products. Advertisements are sophistic since they aim at appealing to the target consumers. Unsophistic advertisements showroom presentations of products and newsletter advertisements (Craig 289). Lesson four Similarities between Stoics & AquinasTop of Form Bottom of Form . The development of natural law has been attributed to Stoic. Stoicism arose in Hellenistic period. Both Stoics and Aquinas believe human beings have a soul which is capable of perception.  Both philosophies agree that human beings have the capacity to assent or resent to presentations made (Craig 28). Both identify God with nature where nature hold cosmos together and cause terrestrial things. Both philosophies consider ethical goals as the kind of life which is consistent with cosmos. Both Stoics and Aquinas recognize that humans have intellectual capabilities which guide them in their moral choices. According to the two philosophies, society wellbeing includes acts which promote co-existence and human wellbeing (Craig 39). Lesson five Aquinas moral philosophy has strengthened my thoughts on personal philosophy. It has supported my thoughts on morality and ethics. According to my thinking, we cannot achieve total happiness in the world since happiness is supernatural and consists of union with God. In order to achieve happiness in life, we must have certain moral virtues which guide us in seeking it in a consistent way. Living things also comprise of matter and substantial form and seek their own perfection (Craig 90). According to my experience, members of the same species have different deg ree of maturity and ability. For instance, adults have more developed cognitive capabilities than a child who is in line with Aquinas philosophy. According to Aquinas, human wellbeing consists of doing acts that are in accordance to human nature and intellectual limitations may prevent us from doing what in good. For instance, mad men commit murder due to their intellectual limitation. Aquinas philosophy emphasis on need of prudence in judgments which is wisdom in human affairs and the reason for the actions. Lesson six Thought experiments are mental hypothesis which are used by philosophers to illuminate dense ideas (Craig 326). Most of them communicate in narrative form or in diagrams. Their role is to increase the man’s understanding of nature. The prisoner’s dilemma is one of the thought experiences I have used before. It analyzes who two individuals may refuse to cooperate when it is in the best interest of them to do so. In this thought experience, two men are ar rested by a police officer without enough evidence to convict them. The police officer separates them and offers them a good deal whereby one should testify against them other. If one betrays the other and the other remains silent, the betrayer is set free while the co-operator is jailed for one year. If both remain silent, they are jailed for

Health - Essay Example It involves managing an individual’s feelings and behaviors, accepting oneself unconditionally and the ability to cope with stress. The social dimension is the ability to create and maintain healthy relationships with other people. It encourages harmony within the family and contributes to the human and physical environment for the goodness of the community. The intellectual dimension is the ability to use an individual’s mind to create the best understanding and appreciating oneself and others. It involves an individual’s ability to be creative in thinking and to expand their knowledge and skills through various activities. Today, technology had changes people lives greatly. Through technology, people are able to interact with others instantly worldwide. In addition, individuals are able to move around fast, the appliances in people’s homes have made life easier thus making the world a better place. According to a fieldwork done since 2003, the American teens use the social media massively and the use social sites like MySpace and Facebook. Some teens opted for MySpace while others preferred to use facebook and there are those who opt to use both. The teens independently chose the kind of social media they wanted to use. Moreover, personal preferences like features, functionality, how to use and design led to the teens choosing one to the other. teens often talk about what they like about and how they perceive the different sites in relation o the values they hold. For example some teen prefer facebook because it seems faster to them as well as it is less competitive than MySpace. In addition, some choose specific social media platforms because of their friends. On the other hand, some teens describe those who use MySpace as those from the ghetto and hip-hop lovers group. In the United States, the social structure is shaped by race, socio-economic status, lifestyle, and education. Social media is fading away as the one that seems trendy

Emotional Intelligence and Transformational Leadership

Emotional Intelligence and Transformational Leadership The title of the research is the Relationship between emotional intelligence and transformational leadership. The first article is discussing about the critical examination of the relationship between emotional intelligence and transformational leadership by the author of Dirk Lindebaum and Susan Cartwright. The second article is discussing about the relationship between emotional intelligence and transformational leadership style and gender comparison of leadership style by the author of Barbara Mandell and Shilpa Pherwani. The purpose of this research is to study the relationship between the emotional intelligence and transformational leadership. This topic is very interesting because it is describing the relationship between the management and psychology. Objectives of this research is to evaluate the relationship between the emotional intelligence and transformational leadership, gender comparison of the leadership style, have contributed to the construct of emotional intelligenc e and its importance in the workplace, comparison and contrast between the two articles. In this research I am going to discuss about how they are relating emotional intelligence and transformational leadership? How they are describing emotional intelligence? And what is the difference between the transactional leadership and transformational leadership? Then how they are analyzing and discussing the relationship between emotional intelligence and transformational leadership in the organization? Dirk Lindebaum and Susan Cartwright article seeks to remedy this efficiency. First, it provides a rationale for utilizing a particular conceptualization of Emotional Intelligence. Second, it synthesizes the theoretical concepts of Emotional intelligence and Transformational leadership and offers an overview of empirical studies that have investigated the interface between the two. It then proceeds to explain briefly the methodological concerns related to common method variance and the implications for research designs. The resultant design of this study explores the relationship between emotional intelligence (EI) and Transformational leadership (TFL), taking account of common method variance (CMV). Finally, the article discusses its findings in relation to previous studies, its limitations, and recommendations for future research (DirkLindebaum SusanCartwright). The Barbara Mandell and Shilpa Pherwani article is providing the types of intelligence, types of mental abilities, models of emotional intelligence, comparison between transactional leadership and transformational leadership, gender comparison of leadership style, measurement instruments, and statistical analysis. In Each article the Mayer and Salovey are giving the definition for emotional intelligence is different in different years. First article is showing the definition of Mayer and Salovey in 1997, they defined Emotional intelligence as, (Mayer Salovey, 1997) ability to perceive accurately, appraise, and express emotion; the ability to access and/or generate feelings when they facilitate thought; the ability to understand emotion and emotional knowledge; and the ability to regulate emotions to promote emotional and intellectual grow. In second article has taken the definition of emotional intelligence from Mayer and Salovey in the year of 1990. Mayer and Salovey defined as, (Mayer Salovey, 1990) emotional intelligence as the ability to monitor ones own and others feelings and emotions, to discriminate among them and to use this information to guide ones own thinking and actions. Both articles are captured the imagination of management scholars and psychologist: emotional intelligence ( EI) and Transformational leadership (TFL). According to Dirk Lindebaum and Susan Cartwright article Emotional intelligence explains 34 percent of the variance in a measure of Transformational leadership (Butler Chinowsky, 2006), which is an above-average percentage in social science research. Both articles are discussing two models of emotional intelligence. In Dirk and Susan article specifying two types of emotional intelligence that are, trait emotional intelligence and ability emotional intelligence. According to Petrides et al. (2007, p.273), trait emotional intelligence defined as emotion-related dispositions and self-perceptions. Trait emotional intelligence relies upon self-report measure (e.g. the Emotional Quotient Inventory, EQ-i) and assesses typical or preferred modes of behavior, whereas the latter uses ability measures (e.g. the Mayor-Salovey-Caruso Emotional Intelligence Test, MSCEIT), with right or wrong answers, and refers to maximum performance in processing emotional information. (Mayer Salovey, 1997). Ho wever, representatives of both the trait and ability Emotional intelligence approach maintain that considerable progress of their respective conceptualization has been achieved in recent years (Mayer, et al., Petrides et al., 2004). According to Barbara Mandell and Shilpa Pherwani two models of emotional intelligence have emerged, these are ability model and mixed model. The ability model defines emotional intelligence as a set of abilities that involves perceiving and reasoning abstractly with information that emerges from feelings. This model has been supported by the researcher of Mayer, Caruso and Salovey (1999); Mayer, DiPaolo, and Salovey (1990); Mayer and Salovey (1993, 1997); and Salovey and Mayer (1990). The mixed model defines emotional intelligence as ability with social behaviors, traits and competencies. This model has found in the writing of Goleman (1995, 1998) and Bar-on (1997). In Dirk and Susan article synthesizing emotional intelligence and transformational leadership this is explored first with regard to the conceptual proximity between emotional intelligence and transformational leadership, followed by empirical studies that examined their relationship. Whilst transformational leadership has been variously defined, Burns (1978) characterizes the transformational leaders as someone who looks for potential followers, seeks to satisfy higher needs, and engages the full person of the followers (p.4). He goes on to suggest that the result is a relationship of mutual stimulation and elevation that converts followers into leaders and may convert leaders into moral agents. Bass and Avolio (Bass Avolio, 1994) have refined earlier research on Transformational leader (e.g. Bass, 1985) and deconstructed the concept into four components. These are denoted as: idealized influence, inspirational motivation, intellectual stimulation, and individualized consideration. Transformational leaders use inspirational motivation to communicate high expectations, often drawing on symbolic messages to provide meaning to their followers work (Bass, 1990). Barbara and Shilpa article describing the transformational leadership of two authors like Bass and Avolio. They defined transformational leadership as leadership that occurs when the leader stimulates the interest among colleagues and followers to view their work from a new prospective. According to Barbara and Shilpa the transformational leader generates awareness of the mission or vision of the organization, and develops colleagues and followers to higher levels of ability and potential. In addition, the transformational leader motivates colleagues and followers to look beyond their own interest towards interest that will benefit the group. In comparison to transformational leadership, Bass and Avolio (Bass Avolio, 1994) described transactional leadership occurring when the leader rewards or disciplines the follower with regards to performance. Burns (Burns, 1978) described transactional leaders as leaders that emphasize work standards, assignment, and task-oriented goals. In addi tion, transactional leaders tend to focus on task completion and employee compliance, and these leaders rely quite heavily on organizational rewards and punishments to influence employee performance. Bass (Bass, 1997) suggested that transformational leaders (TFL) achieved higher levels of success in the workplace than transactional leaders (TAL). He noted that TF leaders were promoted more often and produced better financial results that TA leaders (Bass, 1997). Bass (Bass, 1997) also observed that employees rated TF leaders more satisfying and effective than TA leaders. Bass (Bar-On, 1997) would attribute transformational leaders superior work performance to high EQ-I scores. In recent years, numerous studies have examined empirically the link between emotional intelligence and transformational leadership. The literature review permits the classification of these studies into three prominent streams. Stream1 includes those studies that collected data concerning trait emotional intelligence and transformational leadership from the same source using self-report measures. Stream2 features studies that administered trait emotional intelligence and transformational leadership questionnaires to different raters. Finally, studies pertaining the stream3 used an ability-based measure of emotional intelligence and collected data relative to transformational leadership from a different source. (DirkLindebaum SusanCartwright). In addition Barbara and Shilpa were saying about gender comparison in their article. They specified as the researchers in the past have also looked at the gender differences for both transformational leadership style and emotional intelligence . Although past research on leadership style differences between men and women has been inconclusive, a review of research on leadership and gender consistently demonstrates that women leaders are often negatively evaluated in comparison to their male counterparts, especially when they employ an autocratic leadership style (Eagly, Makhijani, Klonsky, 1992). To analyzing the relationship between the emotional intelligence and transformational leadership both different authors are using the different analysis methods. Dirk and Susan were used two analysis methods. Barbara and Shilpa were used one analysis method. According to Dirk and Susan two subsidiary analysis methods were used by the researcher. These are (1) control for fixed effects and (2) examine the data using randomization. Controlling for fixed effects can be highly desirable as it ensures that estimates are more consistent. In second subsidiary analysis, randomization was used to further examine the relationship between trait emotional intelligence and transformational leadership across all data produced by the same source. According to Barbara and Shilpa hierarchical regression analysis was conducted to examine the predictive relationship between emotional intelligence and transformational leadership style. The analysis also used to examine interaction of gender with emotion al intelligence when predicting transformational leadership style. The analysis also helped the researchers identify gender differences in the relationship between emotional intelligence and transformational leadership style. Conclusion This research was designed to determine the predictive relationship between emotional intelligence and transformational leadership style, as well as determined the gender comparison of leadership style. I find types of analysis for evaluation of relationship between emotional intelligence and transformational leadership style. Finally I find types of emotional intelligence and conceptualization of emotional intelligence, three types of streams to determine relationship, characteristics of leadership, comparison between transactional and transformational leadership from both articles.

Population Explosion

Before the end of the year 2011 the world can expect the population to hit an historic accomplishment of reaching seven billion people. The birth of this seven billionth baby will happen sometime in â€Å"October or November† (Nagarajan). This baby will most likely be born in India due to India having the highest fertility rate of â€Å"fifty one babies every minute† (Nagarajan). So is this an accomplishment for humans beating nature by populating the Earth? Or on the other hand will humans soon have to come to grips with their careless actions of destroying all resources, killing thousands of other species and eventually see the end of the human race at the hands of overpopulation? According to the author of Population 7 Billion, Robert Kunzig, â€Å"people shouldn’t panic- at least not yet† (1). A fair and stable amount of people is needed to keep the human species from dying off. Overpopulation, though, could deplete or destroy Earth’s resources such as food, water, and eventually lead to the breakdown of the ecosystem. With these resources being affected by the human population, the resulting consequences of plagues, wars, and famines could cause one of the few times for the global population to decrease. A global plan of action is needed, but policies such as China’s one-child policy is not even going to be considered by the U. S and many other countries to lower their population. The populations of humans on planet Earth have to face the challenge of providing food, water, and face the accountability for ecosystem breakdown. One famous book, The Population Bomb, a best seller in 1968 written by Paul R. Ehrlich, warned about overpopulation and advocated immediate action to limit population growth. He predicted famines that would follow the revelation of the world but thanks to the â€Å"Green Revolution of the 1970s, an increase in the world harvest averted the famines predicted by Ehrlich† (Zeaman 63). Although disaster was averted â€Å"decades from now there will be likely two billion more mouths to feed, mostly in poor countries† (Kunzig 43). Producing enough food as populations grow is possible but doing so will exhaust finite resources, and especially water will be a challenge. If the world population, which is expected to be eight billion by 2025, continues to be so high, â€Å"forty eight countries containing three billion people will face water shortages† (Hinrichsen). We do have the technology to desalinate ocean water, but this process is several times the costs as getting fresh water. Areas suffering from shortages of water can increase their share of water by capturing rain water and storing it. Finding enough arable land that is not already being occupied by humans will have to be dealt with future populations. China feeds its billion- plus people on less than ten percent of Earth’s arable land† (Kunzig 56). At least space to put all these people is not one of the most pressing issues, as the â€Å"world population could fit in the size of Texas, if it were as densely populated as New York† (Kunzig 48). Though we might have just enough livable land for future populations and land for crops and livestock, plants and animals will have to find space off of what is not already being used by humans. Earth’s biodiversity and ecosystems are in jeopardy, â€Å"with two out of every three species to be in decline† (Hinrichsen). Trees provide habitats for more than â€Å"fifty percent of plants and animal species† (Zeaman 73). Forests lost range from â€Å"twenty percent to fifty percent† (Zeaman 73). In the fourteenth century Europe experienced one of the worst plagues in human history, the bubonic plague. The bubonic plague killed over â€Å"half of the people of western Europe† (Dawling). The development of better transportation routes between Asia and Europe, which allowed rats carrying infected fleas to reach European cities, coinciding with the overcrowding and unsanitary conditions within these cities created an ideal condition for the disease to spread. In Ehrlich’s The Population Bomb similar occurrences were supposed to happen but thanks to institutions like â€Å"the World Health Organization and UNICEF† (Kunzig 45), and also with the development of â€Å"penicillin and smallpox vaccines after World War II† (Kunzig 45), plagues which were expected to be some of the worst humans have experienced, were practically eliminated with the exception of the AIDs virus. Plagues are not as threatening as they were to older cultures as they are today, but wars threaten people of all cultures and time periods. Wars do not only come from â€Å"religious differences, political beliefs, and ambitious rulers, but also population pressures will play a big role in wars of the future† (Zeaman 37). A country with a swelling population might try to take land from a neighboring country, or an overpopulated country, overwhelmed by poverty and social problems, breaks out into internal problems. Psychologists that have studied animals discovered the more crowded animals are together, the more aggressive they are and more prone to attack one another. Could such a mechanism operate in humans as well? Another risk for future humans is the utbreak of famines. Agriculture created civilization, but could dependence put an entire civilization at risk? In undeveloped nations where population growth is the highest, crop failures due to drought, excessive rains, or soil erosion can cause people to starve. Scientist who studied the Earth’s core found evidence of an ancient drought that led them to predict â€Å"that one region of Equatorial East Africa will suffer a mega drought, possibly lasting decades, in the next fifty to one hundred years† (Zeaman 62). This would be a drought of un-parallel proportions that could deteriorate an already unstable region. For the human race to become stable to a degree that does not deplenish the Earth’s resources, while having a population large enough to live through any global catastrophes, is needed for continuing existence. Is a world controversial population control policy that mimics China’s coercive one-child policy the solution? In â€Å"1965 Chinese women were having six children, now it is down to around one and a half† (Kunzig 48). Though the Chinese will continue this policy, the answer for other nations, especially the United States is a clear no. A much less controversial and beneficial policy to not only the country of India but becoming a beneficial program to its people is voluntary sterilization. The procedures which are mostly done to women are being changed to be done on the male population. The scalpel vasectomy costs less and is easier on the man than a tubal ligation on a woman. In less than seven minutes, male patients are walking out of the clinics without even a Band- Aid. An incentive fee of a week’s wage for a laborer would be more acceptably viewed by the global population then having your child taken away from you, like in China. Another way to fight overpopulation in the world’s undeveloped nations where populations incur the most growth is fighting poverty that feeds the world population. Fighting poverty through better education or providing clean water and nutritious food is a step in the right direction. Karl Marx, a nineteenth century communist revolutionary, is another world doom prophesier like Ehrlich that believed â€Å"capitalism creates overpopulation† (Gee). Marx has a right to his own views but his predictions seem to show that capitalism is the problem of over population. The U. S and almost all of Europe is close to or under the world average population growth of one hundred and thirty three percent between 1960 and 2011. In fact the â€Å"less developed world will account for more than ninety five percent of the future population growth† (Kunzig 50-51). In a study on 41,554 households in India, small but growing groups of one-child families appeared due to â€Å"education costs for children attending public or private school. With emphasis these parents have to give their children better opportunities to be successful through a higher education† (Kunzig 36). Will humans become extinct at the hands of overpopulation? The death of the human race will likely not be because of over population. An asteroid or environmental disaster is a bigger threat and less controllable than overpopulation. A country like America will only be affected by â€Å"the population group of fifteen to twenty four being affected by unemployment† (Countries 9) due to the economy suffering from the retirement of so many people at once. Men before the world even hit a billion which happened around the 1800s, were predicting populations of twenty billion people and plagues that would put a dent in the growing global population. Men such as William Petty, a seventeenth century economist, and Thomas Malthus, an eighteen century priest and economist predicted such events that have not and will not occur. Even predictions from a more modern writer, Paul Ehrlich, did not calculate the innovations of the future to be able to adapt for an ever growing population. Population growth is on the decline but will take a generation before stability can be reached. Even just a little education on the issue can make a difference. If women were to have one less child now, then by 2050 that could have the difference of eight billion rather than ten and a half billion.

Managing children on watching television

Managing children on watching television The definition for television is a system for transmitting visual images and sound that are reproduced on screens, primarily used to broadcast programs for entertainment, information, and education. The history of television comprises the work of numerous engineers and inventors in several countries over many decades. The first practical demonstrations of television, however, were developed using electromechanical methods to scan, transmit, and reproduce an image.As electronic camera and display tubes were perfected, electromechanical television gave way to ll-electronic systems in nearly all applications. Commercially available since the late 1920s, the television set has become commonplace in homes, businesses and institutions, particularly as a vehicle for advertising, a source of entertainment, and news. In 2009 78 percent of the world's households owned at least one television set, an increase of 5% over 2003. Television can be used in ma ny ways, such as entertainment, information, and education.Television can be bad but it can be good if we know how to manage with it. The American Academy of Child and Adolescent Psychiatry states that television viewing can be a powerful influence in eveloping value systems and shaping behavior. Most of us are aware that Sesame Street teaches children who are ready for it, letters and numbers. Research on children's behavior, school performance, weight, sleeping habits, and brain development back up the assertion that TV is harming our children.Violent behavior, research has shown that the more hours children spend watching TV, the more likely they are to display aggressive impulses and hostile feelings. This effect has been found to apply whether the televised behavior is performed by a human or by a cartoon character. And aggressive impulses have been found to occur with girls s well as boys and with teenagers and adults as well as children. There are also other behavior that alm ost likely to occur when we let our children watch television such as, kids who watch more TV start smoking at an earlier age, exposure to alcohol use on TV and in music videos (such as on MTV).As a parents what can we do to teach our children to view television as a treat or special entertainment. Many of the following suggestions come from the American Academy of Pediatrics, the first one is observe, how do our children act after watching television? Do the certain behavior increase or decrease? After observing you can decide whether to eliminate certain program or not, short term effects are easier to observe but, long term effects are far more difficult.Listen to our child also can help them to share what are they thinking about the show and let them share their feeling about, by listening we also can ask question and help them to think about what theyVe seen, process it, and clarify values. Monitor the shows children and adolescents are viewing, most programs should be informat ional, educational, and nonviolent. Choose shows that engage through challenging and interesting content, rather than flashy graphics and oise. Make sure programs are age and developmentally appropriate.Provide alternatives, when your child says I'm bored, does it become your problem? Or is it an incentive for your child to be creative? Are the raw materials for creativity available? hobbies, and creative play. There are lots of ways to manage children on watching TV shows. We Just need to learn and do research about how to manage rather than shut the TV and ask your children to study. There is a way to do it. Lastly, manage your children on watching TV well is the key to control their behavior.

Blackbeards Last Stand - the Death of Blackbeard

Edward Blackbeard Teach (1680? - 1718) was a notorious English pirate who was active in the Caribbean and coast of North America from 1716 to 1718. He made a deal with the governor of North Carolina in 1718 and for a time operated out of the many inlets and bays of the Carolina coast. Locals soon tired of his predations, however, and an expedition launched by the Governor of Virginia caught up with him in Ocracoke Inlet. After a furious battle, Blackbeard was killed on November 22, 1718. Blackbeard the Pirate Edward Teach fought as a Privateer in Queen Anne’s War (1702-1713). When the war ended, Teach, like many of his shipmates, went pirate. In 1716 he joined the crew of Benjamin Hornigold, then one of the most dangerous pirates in the Caribbean. Teach showed promise and was soon given his own command. When Hornigold accepted a pardon in 1717, Teach stepped into his shoes. It was about this time that he became â€Å"Blackbeard† and started to intimidate his foes with his demonic appearance. For about a year, he terrorized the Caribbean and the southeastern coast of the present-day USA. Blackbeard Goes Legit By mid-1718, Blackbeard was the most feared pirate in the Caribbean and possibly the world. He had a 40 gun flagship, the Queen Annes Revenge, and a small fleet captained by loyal subordinates. His fame had become so great that his victims, upon seeing Blackbeards distinctive flag of a skeleton spearing a heart, usually simply surrendered, trading their cargo for their lives. But Blackbeard tired of the life and intentionally sank his flagship, absconding with the loot and a few of his favorite men. In the summer of 1718, he went to Governor Charles Eden of North Carolina and accepted a pardon. A Crooked Business Blackbeard may have wanted to go legit, but it certainly didnt last long. He soon entered into a deal with Eden by which he would continue to raid the seas and the Governor would cover for him. The first thing Eden did for Blackbeard was to officially license his remaining ship, the Adventure, as a war trophy, therefore allowing him to keep it. On another occasion, Blackbeard took a French ship laden with goods including cocoa. After putting the French sailors on another ship, he sailed his prize back, where he declared that he and his men had found it adrift and unmanned: the Governor promptly awarded them salvage rights†¦and kept a little for himself, too, of course. Blackbeard’s Life Blackbeard did settle down, to an extent. He married the daughter of a local plantation owner and built a home on Ocracoke Island. He would often go out and drink and carouse with the locals. On one occasion, pirate Captain Charles Vane came seeking Blackbeard, to try and lure him back to the Caribbean, but Blackbeard had a good thing going and politely refused. Vane and his men stayed on Ocracoke for a week and Vane, Teach and their men had a rum-soaked party. According to Captain Charles Johnson, Blackbeard would occasionally let his men have their way with his young wife, but there is no other evidence to support this and it appears to simply be a nasty rumor of the time. To Catch a Pirate Local sailors and merchants soon tired of this legendary pirate haunting the inlets of North Carolina. Suspecting that Eden was in cahoots with Blackbeard, they took their complaints to Alexander Spotswood, Governor of neighboring Virginia, who had no love for pirates or for Eden. There were two British war sloops in Virginia at the time: the Pearl and the Lyme. Spotswood made arrangements to hire some 50 sailors and soldiers off of these ships and put a Lieutenant Robert Maynard in charge of the expedition. Since the sloops were too large to chase Blackbeard into shallow inlets, Spotswood also provided two light ships. Hunt for Blackbeard The two small ships, the Ranger and the Jane, scouting along the coast for the well-known pirate. Blackbeards haunts were well known, and it didnt take Maynard too long to find him. Late in the day on November 21, 1718, they sighted Blackbeard off of Ocracoke Island  but decided to delay the attack until the next day. Meanwhile, Blackbeard and his men were drinking all night as they entertained a fellow smuggler. Blackbeard’s Final Battle Fortunately for Maynard, many of Blackbeards men were ashore. On the morning of the 22nd, the Ranger and the Jane tried to sneak up on the Adventure, but both became stuck on sandbars and Blackbeard and his men couldnt help but notice them. There was a verbal exchange between Maynard and Blackbeard: according to Captain Charles Johnson, Blackbeard said: Damnation seize my soul if I give you quarters, or take any from you. As the Ranger and the Jane came closer, the pirates fired their cannons, killing several sailors and stalling the Ranger. On the Jane, Maynard hid many of his men below decks, disguising his numbers. A lucky shot severed the rope attached to one of the Adventures sails, making escape impossible for the pirates. Who Killed Blackbeard?: The Jane pulled up to the Adventure, and the pirates, thinking they had an advantage, boarded the smaller vessel. The soldiers came out of the hold and Blackbeard and his men found themselves outnumbered. Blackbeard himself was a demon in battle, fighting on despite what was later described as five gun wounds and 20 cuts by sword or cutlass. Blackbeard fought one-on-one with Maynard and was about to kill him when a British sailor gave the pirate a cut on the neck: a second hack severed his head. Blackbeards men fought on  but outnumbered and with their leader gone, they eventually surrendered. Aftermath of Blackbeard’s Death Blackbeards head was mounted on the bowsprit of the Adventure, as it was needed for proof that the pirate was dead in order to collect a sizeable bounty. According to local legend, the pirates decapitated body was thrown into the water, where it swam around the ship several times before sinking. More of Blackbeards crew, including his boatswain Israel Hands, were captured on land. Thirteen were hanged. Hands avoided the noose by testifying against the rest and because a pardon offer arrived in time to save him. Blackbeards head was hung from a pole on the Hampton River: the place is now known as Blackbeards Point. Some locals claim that his ghost haunts the area. Maynard had found papers on board the Adventure which implicated Eden and the Secretary of the Colony, Tobias Knight, in Blackbeards crimes. Eden was never charged with anything and Knight was eventually acquitted in spite of the fact that he had stolen goods in his home. Maynard became very famous because of his defeat of the mighty pirate. He eventually sued his superior officers, who decided to share the bounty money for Blackbeard with all crew members of the Lyme and Pearl, and not only those ones who had actually taken part in the raid. Blackbeards death marked his passing from man to legend. In death, he has become far more important than he ever was in life. He has come to symbolize all pirates, which in turn have come to symbolize freedom and adventure. His death is certainly part of his legend: he died on his feet, a pirate to the very last. No discussion of pirates is complete without Blackbeard and his violent end. Sources Cordingly, David. Under the Black Flag. Random House Trade Paperbacks, 1996, New York. Defoe, Daniel.
