Changes in the environment Essay

The changes in environment that people in space experience also mean changes in significant cues. For example, there is the absence of a fixed horizon that is expected to reduce the efficiency of a person’s perceptions of shape, distance, location and motion (Man-Systems Integration Standards, 2006). The noise aspect is also considered as a human factor particularly in the design of habitat (Special Issue on the International Workshop on Human Factors in Space, 2000). One of the critical requirements in space is the ability of people to communicate with each other. There are noise exposure limits that are established because outside Earth, even low levels, especially when it is intermittent noise, can affect the communication system and human performance especially in complex tasks. Noise also causes fatigue, distraction, irritation and aggressiveness which are already under the scope of psychology but nonetheless, far from what are needed by the people in space (Man-Systems Integration Standards, 2006). The humans must be able to acclimatize themselves to changes in pressure associated with space travel. Because humans are used to atmosphere with 21% oxygen at sea level, equipment and traveling environment are adjusted to maintain an equivalent partial pressure that would sustain life. Pressure values vary from person to person depending on his or her degree of acclimatization to altitude. As a rule, people who are accustomed to higher altitude require less total pressure compared to people who are not accustomed to higher altitude. The partial pressure for normal people who work in space are usually maintained above 152 mm Hg while those who are not accustomed to such environment must maintain a total pressure above 417 mm Hg (Man-Systems Integration Standards, 2006). Psychology The management of human’s psychological state in space is indeed a part of NASA’s standards. â€Å"Human factors research and technology will also ensure that interpersonal interactions are planned maintain a healthy and constructive attitude, thus enhancing productivity and mission success among an international culturally-diverse crew (Man-Systems Integration Standards, 2006). † This implies an assumption that metal and psychological performance and human interactions could have a very significant role in the success of an exploration. Conclusion With the advent of space age, the human factors research contributes significantly especially to the present knowledge in flight, which involves the participation of humans. Success in space missions would be doubtful without consideration of the human factors to which any mission’s success or failure depends. References Brown, D. L. , DeVilbiss, C. A. , Ercoline, W.

Faculty of Business Environment and Society - Coursework Example The greatest challenge in international trading is the time taken by goods from an exporter to an importer from the time when an order is placed by an importer (Chisholm & Chisholm, 2009). This delays make both parties operates under uncertainties and risks; the risk that they have paid for some goods that may never be delivered or the risk by the exporter that they have shipped goods that they might never receive payments for the same. Trade finance therefore comes in to mitigate those challenges with the risks by ensuring that exporters have enough money or rather capital so as to ensure that there is efficiency in international market place. Financial products imply the various methods that are employed when it comes to international trade transactions. This refer to use of various money management methodologies different investment and banking service to satisfy both the exporter and the importer that they are secure in terms of recovering the money (Chisholm & Chisholm, 2009). These also boost confidence in trade because the exporter can lent more goods to the importer. In executing these strategies both parties are subject to various laws both the port of export and at the destination port. Pre-shipment and post shipment are the two key points in international trading. Post-shipment is a situation whereby the exporter export the goods and after shipping it waits for payment at a later date either immediately after delivery or after sale. Pre-shipment involve exporter entering global market or importer first showing interest in placing an order. The exporter often needs financial assistance in order to extend the same credits to the importers if at all he is to remain competitive like other exporters. At the same time the exporter needs finance to continue its operations in producing more goods for export and that is the reason why he need the payment of goods dispatched as quickly as

Summary Strong Response to Damation of a canyon article Essay

Summary Strong Response to Damation of a canyon article - Essay Example In this article, the author took an in-depth look at the ramifications of damming a place called Glen Canyon, a location on the border between Utah and Arizona, in order to create Lake Powell. In making his observations, the author managed to launch worldwide environmental concerns regarding the actual effects of dams on the greater community. As the author describes the setting of Glen Canyon as it existed naturally, he tells about a river trip he took down the Colorado River in this area in which the current of the river was sufficient to drive his raft nearly 150 miles in 10 days through a rich environment full of life. He then compares this experience with a couple of seasons he spent working as a seasonal park ranger at the Powell Lake reservoir. This establishes his credibility in having known the canyon both before and after the creation of the dam in this vicinity and thus able to assess the positive and negative changes that were brought about as a result. Having established his credibility as someone familiar with the area both before and after the industrial changes, Abbey then provides full disclosure telling his audience about his environmental interest and generalized anti-industrial stance. However, in making this admission, he also makes a feeble claim that there are a growing number of Americans who join him in these sentiments. While this would seem to weaken his argument, his further discussion reveals that there are well-founded reasons for him to feel the way he does as he launches the article into a more specific investigation of the effects of the construction of the dam. Abbey strengthens his argument against the dam by pointing out the environmental damage that had been realized by the dam. The first problem introduced by the dam is described most accurately as the ‘bathtub ring’ effect. The purpose of building the dam was primarily for the

Search and Rescue in Residential Fire Structures Research Paper

Search and Rescue in Residential Fire Structures - Research Paper Example It is vital to the safety of our society that researchers continue to enhance the technologies that allow fire fighters to do their jobs in the safest and most effective fashion possible, especially those working in residential structure fires and residential search and rescue. Residential structure fires are responsible for approximately two to three thousand civilian deaths per year since 1997, but these numbers have been dropping due to improved fire prevention education, early fire detection, and fire suppression technologies being used, and also the improved technologies and equipment available for search and rescue efforts (USFA, 2008). These search and rescue technologies fall into two major categories: those devices that make it easier for fire fighters to find and save those victims trapped within a burning building and those technologies that protect the fire fighters' own lives, which indirectly will save even more lives than the direct equipment. Technologies that allow f ire fighters to rescue those victims who have been trapped within a burning building mainly include those which allow the rescue workers to find those individuals more quickly. The primary and most impressive piece of equipment in this category is the thermal imaging camera. A thermal imaging camera helps the fire fighters to see people more easily through dense smoke or haze, by analyzing the image of a trapped figure and â€Å"convert[ing] the 'thermal signature' to a visible image† (Marlow Industries Inc, 2008). These cameras are able to convert the most minute differences in the temperature of objects into a visible light image for the fire fighter using the camera to view, and they work even in complete darkness as they do not require any ambient visible light to resolve the images (FLIR Commercial Vision Systems, n.d.). This combination of processes means that a thermal imaging camera can be used by a fire fighter to look into a dark or smoke-filled room and determine i mmediately if there are any people within the room who need to be evacuated from the building. The image will also show the fire fighter if there are any flames or ignition sources within that room (FLIR Commercial Vision Systems, n.d.) Such cameras work by visualizing an image using infrared radiation instead of visible light sources. They are able to produce images at high resolution through heavy smoke due to the fact that the infrared radiation used has a longer wavelength, reducing scattering off of particulate matter in the air. (FLIR Commercial Visions Systems, n.d.). Some cameras are even able to transmit these images to a commander outside the building, allowing him or her to better control the situation within the building based on the real-time data being received (Santa Clara County Fire Department, â€Å"High-Tech and Specialized Equipment, n.d.). These cameras are also sometimes of adjustable sensitivity, to allow for varying temperature ranges in the space being view ed. They can be more sensitive for narrow temperature ranges, such as looking into a hot room, and less sensitive cameras for situations where temperatures vary more widely, such as trying to locate an individual in a smoky but relatively cool room (Amon, Bryner, & Hamins, 2005).

Explanatory synthesis Essay Example | Topics and Well Written Essays - 1000 words

Explanatory synthesis - Essay Example Social psychology challenges the most basic assumptions of human behaviour and nature, and to a big extent the predictability of the social world. Psychologists look at the different kinds of situations in the world in a very distinct and different way from that of other people and they apply the beliefs and insights of psychology to the unfolding social events around them. Individuals respond differently to social influences by either choosing to comply, identifying, complying or internalizing. Compliance is seen as a form of agreement to the particular situation at hand, but deep from within the person might be in no way convinced. Situations in a big way determine the kind response a person will extend to particular situation. In the text, Ross argues that the type of information about personality that most of the people would possess before predicting personality proves to be of relatively little value. Research has indicated that when faced in certain situations such as these, i t is not possible to predict with accuracy how particular people will respond. Situational behaviour in relation to an individual’s actions can be demonstrated in the parable of the Good Samaritan. The story is about a Jewish man who was travelling to Jericho, but bandits attacked him and left him lying half-dead by the roadside. A priest passes him and offers him no help, until a Good Samaritan whose stereotype hated the Jews stopped by and offered the man assistance. The study experimenters of social philosophy recruited 67 students from the Princeton Theological Seminary, telling them that it a study about religious education and vocations (Hoyk, Hersey 49). Unknown to these participants, they were to be subjected to their own personal Good Samaritan attributes. The requirement was that they would fill questionnaires on their personality then walk to a nearby room to give their talk. On the doorway, a man was lying doubled over with his eyes closed and coughing. All the pa rticipants would not escape the site of the distressed man and the biggest question was, would they be willing to offer any assistance to the man? In their assumption, the experimenters thought that it would be dependent on how much the participants were hurried, and thus devised a way of manipulating them, by giving each a map and one of the instructions which either stated that the participant was late and had been a few minutes late. Another stated that the assistance was waiting for the participant, yet the other stated that it would take another few minutes before the interviewers were ready, but had the option of proceeding over. This created conditions of high, medium, and low hurry and thus some students left the office thinking that they needed to be quick, others less while the rest felt relaxed. Each of the three conditions were was also divided into two, half of them were required to give a talk on the Good Samaritan and the other half on prospects for seminary graduates . This helped the experimenters to assess both the effects of hurry and the talk they were to give on students’ helping behaviours. The outcome of the experience was classified into two classes, which included in a hurry and could not stop and judge on context. From the results, only 40% of the students offered some form of assistance to the people, with a few stepping over the apparently injured man, but it was evident that the amount of hurry they were in had a
