Comparison of The Judges House versus The Signalman :: essays research papers

I think that mystery stories are so popular with people today, and with the last couple of generations because they are so intriguing. The author tries to give the story an element of surprise and also put twists in the tails to keep the reader guessing. Rather than just watching a film it allows the reader to build up their own imagination and interpret the story in their own way. The author will also try to integrate a ghost or spirit into the story, whether it be physically there or just psychologically, this gives the sense of mystery and usually results in the protagonist of the story dying. During the Victorian era mystery stories were especially popular, this was due to television and cinema not being in existence, so people had enliven themselves in other ways, in this case with books. In Victorian times religion was cogent and people believed in God more than people today, this meant that people thought what happen in mystery stories was very plausible. However with the adva ncement of science, people regard mystery stories as fully fictional, conversely some individuals and groups do still believe in the existence of ghosts and spirits. The two stories, ?The Judges House? and ?The Signalman? have atmosphere built up through the setting of the story as well as other things including the characters and also the dialogue. First of all, the judge?s house has a very weird sort of setting. It is set in a large, old house with high windows and tall walls, basically a very stereotypical sort of house for a mystery story. However this decrepit house is situated in the middle of a community, with a wide array of people and vehicles there. This sort of area you would expect to be safe, however this could have given Malcolm Malcolmson, the protagonist, a false sense of security as the house has high walls isolating it from the rest of the community. The author describes the house as ?a fortified house than an ordinary dwelling? this suggests that it was not just a few fences around the house, rather iron bars on windows and large iron gates, these are the things you would stereotypically relate to this type of story. ?The Signalman? is not the kind of setting you would expect for a story of this nature, it is set on a railway cutting which is far from stereotypical however a railway cutting could be seen as an industrial area which can be associated with gloominess, fog and smoke.

Grant, Hero of A Lesson Before Dying Essay

How we act or react in difficult situations defines our persona. Sometimes these situations provide opportunities to be a hero. After reading Grant Wiggins’s own definition of a hero, it is apparent that Grant becomes a hero. Grant states, â€Å"A hero is someone who does something for other people. He does something that other men don’t and cant to. He is different from other men. He is above other men. No matter who those other men are, the hero, no matter who he is, is above them.† Grant becomes a hero by earning an education to become a teacher, undergoing psychological changes, and counseling Jefferson to die with dignity. A hero is different from others and does something others cannot. Grant’s drive to defy stereo type, become a teacher, and contribute to the community demonstrates that he is a hero. Grant is an African American son of cane-cutters who worked on a Louisiana plantation. He grew up working a labor job and was expected by society to continue as a laborer. Through determination he was able to escape his surroundings to earn a college education. He returns as an educated university man hoping to make a positive impact on society, but is still looked down upon. College gave him a new perspective and educated way of speaking and thinking, but he was still not equal to the whites. Grant continued to persevere through segregation and unfair treatment. He maintained his goal of making a difference by teaching in a church without desks or other supplies. Grants ability to escape his environment and stereotyping, earn an education, and return to his community to make changes, makes him different from others in his community. Grant was different from others and taught in conditions that most could not. Grant is a hero. Grant proved himself a hero, not only by overcoming struggles with racism, but with overcoming struggles within his own mind. A hero is above all other men. Many times a change must take place for man to become a hero above all other men. Throughout the novel, Grant undergoes psychological changes that allow him to become a hero. Grant’s life is filled with rage for the way he is treated by whites. Eventually this rage becomes self-loathing and cynicism, because he feels he is taking the unjust treatment from whites lying down. This downward spiral causes him to alienate himself from people he loves and feel that the community is helpless. During a conversation with Vivian, Grant says, he cannot face Jefferson because he cannot face himself and his own life. Vivian helps Grant realize that he has left the South in the past, has returned, and still has not left. This helps him realize that he is there for a reason. Another change happens when he accepts the task of helping Jefferson. At first Grant is angry and believes that Miss Emma wants him to perform a difficult and maybe impossible task of convincing Jefferson to die with defiance and character. After accepting this task and dealings with Jefferson, Grant realizes what a hero is and he can have an impact on the community. Finally when Grant breaks down in front of his students he realizes that he is ready to connect with the children that he has been so strict with. Many heroes have to overcome an inner struggle to realize their potential for greatness. Eventually through his interactions with his family, Vivian, Jefferson, and students he realizes to view everyone positively which gives him the strength and courage to make an impact in his community. Grant’s actions with Jefferson embody the heroic effort of doing something for someone else. Jefferson is thought of as an animal, and even compared to a â€Å"hog†. Grant wants Jefferson to believe that he is more than convict and just a black man. Grant wants Jefferson to believe that he can change society. Grant visits Jefferson regularly, councils him, gives him a radio, and hope. Before Jefferson’s death, Grant confides in him and says, â€Å"My faith is in you, Jefferson.† Through his efforts and faith, Jefferson completes his transformation into a dignified human being. Grant’s perspectives change throughout the novel as a result of his interactions with his family, Vivian, Jefferson, and his students. When given the opportunity to be a hero, he accepts and becomes a hero. His escaping his environment and stereotyping to become a teacher, overcoming psychological struggles, and helping Jefferson die with dignity proves that he is a hero in the novel.

Computing in civil engineering proceedings of the 2011 ASCE International Workshop on Computing in Civil Engineering Essay

Studies of construction management address the phenomena of construction problems and explore the nature of construction technology. Manufacturing technologies are categorized into mass, unit and continuous process of productions. Construction technology is classified as a unit production through contrasting construction activities and fabrications. Although the efficiency of construction technology is low in terms of unit production, it is associated with benefits such as zero stocks and flexibility. This report provides a description of materials/techniques used in the current construction of modern domestic properties, industrial unit properties, their comparison and critical analysis of the performance of building structures. It also encompasses on the principles used by builders to perform their functions, characteristics and behaviour of internal materials used in the construction. People have been looking for efficient production systems since the industrial revolution. However, most projects are still built under traditional way of one-of-a-kind production. Application of IT in construction has also failed to produce the intended results. Therefore, nature of construction technology needs to be understood more in order to explain inefficiencies that are surrounding the technology and theory that solves the construction problems (Sarkar 2008). According to Daft (2004), technology refers to the tools, machines, actions and techniques used in transforming organizational information and materials (input) into products and services (output). 1.0 Construction technology                It involves the study of construction techniques to successfully achieve the design of the structure with the recommended specifications (Sabnis, 2011). It includes temporary work and study of construction equipment needed to facilitate the construction process. The recent trend is towards constructing taller and lighter buildings. In order to achieve such buildings, sophisticated equipment needs to be employed in the construction process. 1.1 Current construction techniques/materials                The current methods of construction provide important benefits to developers and housing authorities which reduces the emphasis of on-site activity. This criterion is important particularly in the time of increasing demand of an already stretched labour force. Any new implementation of doing things is faced with risks, but such risks can be mitigated through having good planning and project management. Yvette Cooper, a planning and housing minister quoted, â€Å"people must ensure that the new homes they are constructing are affordable to the next generations.† This report shows that it is easier to build cheaper and faster using modern construction techniques whilst keeping high quality of traditional methods. 1.1.1 Modern methods of construction (MMC)                Modern techniques of constructing houses developed as early as 1945 after WWII, it was used by most of the developed countries such as Germany during buildings fabrication after WWII. Later these techniques spread in many countries and they are commonly used in India during the construction process. As technology, construction knowledge and manufacturing processes increase so do the number of available methods of house construction increases to house builders. Modern Method of construction is a collection of new relatively construction techniques aimed at offering advantages over traditional methods (Altenbach, 2013). Conventionally, this is an area pioneered by self builders, mostly in terms of sustainable construction. As developers’ sticks continually to the proven construction techniques that satisfy buyer demand, self builders have been willing to research, try and invest something different so as to achieve individual homes that meet their need. In an effort of increasing housing demand, shortage of skills and the set targets by Code of sustainable homes, many governments are encouraging the house-building sector to develop and use MMC technique in an attempt to meet these challenges. Most of these modern construction techniques evolved from their traditional predecessors. Techniques such as structural insulated panels (SIPS) and thin joint systems with Air Crete blocks are part of the on going evolution of timber frame and masonry construction (Kuzio 2009). Other familiar techniques have developed in the larger scale commercial construction. This has brought alternatives with interesting qualities of house building. Development of steel frame systems and in-situ concrete techniques led to the development of insulated concrete forms (ICF). 1.1.2 Advantages of modern methods of construction Reduced impact on residents and effect of weather on production Controlled manufacture and reduced fuel consumption and disruptions as a result of fewer materials delivered. Reduced construction defects and time consumed. High quality buildings 1.1.3 Modern domestic properties 1.1.4 Illustrations                Larger construction components can be incorporated into either MMC dwellings or conventionally built. They are not full housing ‘systems,’ but they are factory made or site-assembled. This category comprises of the following components and sub-assemblies. This involves a series of assembled components and pre-fabricated ground beams to form quick and accurate foundations (Koerner 2005). These are pre-fabricated panels designed specifically for floor construction. Fewer on-site labour hours are needed per square meter of floor, and the reduced work at heights has safety and potential health benefits (Hearn 2012). It involves designed pre-fabricated panels specifically for pitched roofs. These panels are very stiff which are designed to leave the loft free of props and struts, thus allowing easy production of ‘room’ in the construction of the roof. These roof cassettes make the building become water weight more quickly than cut roof constructions or conventional trussed rafter. These are roofs assembled at ground level before the shell of the dwelling is constructed. It can be craned into place immediately the superstructure is in place hence creating a weather tight structure more quickly rather than assembling the roof in situ (Corum Scotland 2010). Factory made dormers are used to speed up the roof watertight making process. Pre-fabricated lightweight chimney stacks made from factories are mounted on the roof structure without using masonry flue, thus making them suitable for construction of a lightweight frame. These chimney stacks can accommodate flue liners hence functioning with combustion appliances. Wiring looms                Cabling systems are manufactured in a way that they can quickly be assembled with relatively unskilled labour. They are made of various lengths terminated with plugs that are plugged into sockets and other electrical items (Quinn 2008). Standards are critical steps from development and research to marketplace adoption. Today, many industries are faced not only with managing technological development march, but also with pressures of how to do so cost-effectively, efficiently and with environmental and public safety being in mind. The appearance, energy efficiency, component materials and habitable structures’ environmental impacts have dramatically changed over the last few years. This is as a result of successful standardization of processes, new materials and technologies. This section provides a sample of more recently developed shows and construction technologies, which has been facilitated by provision of the needed standards by ASTM international’s technical committees. These standards have swept off technologies of new construction to the drawing board and into the currently built environment. A Building’s Skin                5488940117475Exterior Insulation and Finishing Systems (EIFS) were used in Germany after WW II to resurface buildings that were damaged by the conflict ravages. They are lightweight, systems of multi-layer barrier that helps in keeping moisture from outer walls. With several components, from foam insulation panels fastened to the base and a substrate coat, to the finishing coat and reinforcing mesh, EIFS is a complex system with materials required to connect successfully for years so as to keep moisture at bay (Noble 2011). EIFS standards development has been the key role of ASTM international Committee E06 on buildings’ performance since 1990’s. Their subcommittee E06.58 on finishing systems and exterior insulation published its first EIFS standard, test methods used in determining breaking strength tensile of reinforcing mesh of glass fibre. This publication was for use in class PB finishing systems and exterior insulation, after it was exposed to sodium hydroxide solution in 2000. Stone masonry Veneer                548894093980The design freedom and cost savings offered by the products of stone masonry veneer have led to their increased use in architectural projects. In comparison to natural stone, manufactured stone veneers can be precisely colored, reinforced with steel, and have a predictable and durable life. The appearance consistency of the manufactured products makes repetitive use of materials as a trim or ornament economically feasible. Additionally, older structures can be renovated with manufactured veneer stones that replicate the deteriorating stone’s appearance (Gunn 2012). It is a technology in which sealant adhesives are used to attach the glass to a building. In the last 20years, structural glazing has experienced exponential growth. It has been in use in industrial construction and other city buildings all over the world. Wood-plastic Composites                Since 1990s, recycled plastic and wood waste has been used as environmentally friendly and economic alternatives for decks. Components such as cladding, railings, molding, siding and trim, door frames and window; and structures such as small park benches. Concrete, which have been in use for a long time in construction of roads and structures is developing in a way that make it less expensive, more varied, safer, easier use and even more environmentally friendly. For example, a self-consolidating concrete that flows into forms was proposed in 1980s’ theory by a Japanese scientist. It has recently become viable as it used in infrastructural projects around the world. It properties are achieved by applying high-range-water-reducing mixtures; it increases the total quantity of fines applying admixtures that modify its plastic state viscosity (Li 2011). The innovative building enclosures’ design relies less on past successful precedents than use of building science. This is a result of changes in methods and materials resulting from building innovation technology. Earlier building enclosures were only expected to provide a degree of environmental separation and be durable, but the recent structures must address issues like day lighting, energy efficiency, fire safety, thermal comfort, and indoor air quality and carbon footprint (Grondzik 2008). In half a century ago, wall performance requirements were outlined which are now applicable to all components and enclosure systems. The following are the major considerations that were identified: Rigidity and strength Control of heat flow Control of airflow Control of water vapour flow Liquid water control movement Durability and stability of materials Fire, aesthetic considerations and cost Since the time of Hutcheon, additional objectives such as environmental impact consideration associated with building materials and methods and the need to provide secure and safe buildings have been adopted. The acceptable requirements of wall performance were implicit within traditional materials and methods of construction. With the modern building science advent, they have become more explicit in response to technological innovation. The table below summarizes the requirements of contemporary performance and their corresponding assessment parameters. Moderator versus separator                A critical principle used in building science involves the difference between moderation versus environmental separation. For example, fire and smoke control movement is a strategy that attempts to completely separate fire and smoke from the indoor environment. The approach employs a fire-related assembly that fully controls leakage of smoke by virtue of the construction of its airtight and in some cases, the air pressures’ control between compartmentalized spaces. Moderation involves a strategy where the difference between outdoor and indoor severity environments is moderated within the tolerable threshold. For example, heat transfer control does not seek to minimize the rate to zero, but to a level that satisfies energy efficiency, comfort requirements, and the control of wetting/condensation. The following table summarizes the key control strategies for building enclosures’ design, which is involved in moderation strategy. A review of the corresponding control strategies and physical phenomena indicates the control of moisture migration is of the most important control function that needs to be addressed by designers. Problems of moisture in buildings are common and vary broadly in consequences and types. These consequences range from cosmetic flaws to structural failure and in some cases the occupants’ health can be affected adversely as in the case of mold growth leading to respiratory and allergic problems. 2.0 Range of construction forms 2.1 Provision and access of internal division of spaces within buildings                Service integration should be jointly considered by the architect/designer, service and structural engineers. The interface between the fabric and the structure together with the service installations can cause problems. These problems can be in terms of the need to have re-route services within the structural elements or the purpose of passing through those elements (Luraghi 2008). Both structural and non-structural integration methods should be considered. The following are some of the spaces and divisions that an architect needs to consider. They should be installed so as to provide access to a building roof. The installation and design of the anchorage and the attachment system for the ladders should be described in MMAH standard supplementary. Fuel-fired appliances should be installed in service rooms from the building’s remainder by fire separations with the fire rating resistance which is not less than one hour. A more than 600 mm high roof space needs to be provided with floor access immediately before the hatchway that is not less than 550 mm by 990 mm or by a stairway. It consists of duct spaces and ceiling, which is more than 600mm wide and 1200mm high, shall have inspection doors. It should not be less than 300mm in both vertical and horizontal dimensions placed so that the entire space or duct interior can be viewed (Kuzio 2009). A fabric is a material structure selection, engineering, proper design, installation and fabrication of all work together to ensure a sound structure (Foster 2010). The role of material in the structure’s performance makes the selection process important. This is true particularly with air-supported and tensile structures because their frames, as well as their membranes carry the load. Membrane materials                Fabrics are typically laminated and coated with synthetic materials for environmental resistance and greater strength. Most of the widely used materials are polyester coated or laminated with PVC, woven fiberglass that is coated with silicone or polytetrafluoroethylene (PTFE). Films, Meshes and other materials also have appropriate applications. Polyesters                It is the most frequently base material used due to its cost, durability, strength and stretch. They are coated or laminated with PVC films and thus they are the least expensive for long-term fabrications. Laminates consist of vinyl films over knitted or woven polyester meshes. Coated fabrics typically use a high-tensile, high-count coated fabric with a bondable substance at the base for extra strength. Lighter fabrics are commonly used insulated and acoustic liners suspended beneath an envelope of a structure. For long-term exterior application, heavier materials are needed: fabrics with top coatings of PVF or PVDF (Zhu 2011). These top coatings are responsible with providing a protective finish to withstand environmental degradation. Vinyl-coated polyester                It is a common fabric used when producing flexible structures, such as canopies, walkways, custom-designed awnings, smaller air-supported structures, tent hall and light member-framed structures (ManCuso 2012).

Physiochemical Hygroscopicity, Swell and Shrinkage due to moisture changes 3.2 Comparison of materials/techniques used in construction                The use of steel in the residential construction and housing sector has grown rapidly over the last ten years. This has been facilitated due to the growing appreciation of the performance benefits arising from the nature of the off-site of the construction process, which is particularly important in mixed-use or urban buildings. Steel construction technologies of an off-site increase the speed of construction and improve the final quality of the building, and can add points to the Code for Sustainable Homes. The main steel market in this area is in multi-storey residential buildings, and mostly mix-use buildings. Domestic buildings versus industrial buildings                A building classified as domestic is one which an individual uses as a dwelling place and provides separate family living quarters for separate family units (Richardson 2008). On the other hand, building not used in connection with a residence and not located on the same parcel as a residence, it is classified as industrial property. Most of the industrial/commercial buildings have been using pre-fabricated construction such as ceiling panels, prefab wall panels, flooring system and plasterboards to create interiors of offices (Domone 2008). Prefab materials provide the option of buildings’ customizing for specific needs such as water and fire resistance and soundproofing. However, individual owners of homes have not yet gained enough confidence with prefab construction. This increases its demand for commercial spaces and from large developers but use by individuals in their homes is yet to gain popularity. 4.0 Critical review of how building structures perform                Organization structure may be considered the organization’s anatomy, providing the foundation in which the organization functions. Hall (1977) noted from simple observation that an organizational structure affects its members’ behavior. The particular building’s structure is a major determinant of the people’s activities within it. Hall suggested two basic functions of the structure each of which may affect organizational performance or individual behavior within the industry. First, they are designed at least to minimize or regulate individual variations’ influence on the organization (Brown and London 2000). Organizational structure is also the setting in which decisions are made, power is exercised, and organization’s activities carried out. Van de Ven (1976) highlighted the structure’s importance both at the subunit levels and the organization for the performance of organizations. Conclusion                Construction technology produces goods and provides services at the same time. The construction process is having low predictability and is highly uncertain. Many intermediate items are integrated and created by human operations with low standardization, mechanization and automation. The benefits of construction technology include high flexibility, zero stock, and satisfactory social needs. As these benefits appreciated, industry that is responsible with construction should consider improving integration of construction job site activities. Thus, we should examine and understand the construction technology fundamentally before successive e-construction programs and construction automation. References Altenbach, H. (2013).

Analyze Psychology Aritcles

Analyze Psychology Aritcles Introduction The study of human behavior has been in existence for many centuries but has only gained prominence in recent times. This can mostly be attributed to popularization by the media especially in the West. Psychologists and behavioral profilers have been gathering valuable data pertaining to the reasons behind any behavior exhibited by different people. Advertising We will write a custom essay sample on Analyze Psychology Aritcles specifically for you for only $16.05 $11/page Learn More They have managed to do this by using psychological theories formulated to facilitate further understanding of how the brain works in forming behaviors. As such, psychology can be described as a field of study that studies behavior. In this study, an analysis of five articles shall be provided. An explanation of why the topics of these articles are related to psychology shall also be offered. Article one The article â€Å"Sleep May Be Nature’s Time Management Tool† by Benedict Carey sets out to provide a discussion as to the role that sleep plays in the lives of human beings and animals. The author states that no one really knows why sleep exists therefore setting the context for the article in which she advances the numerous theories that are advanced as to the role that sleep plays. The central theme advanced by the article is that the ultimate role of sleep may indeed be time management. Structure wise, this article is well formatted as the author begins by giving a brief overview on sleep and the ambiguity with which its role is viewed by members of the society thus laying a proper foundation for the main discussion of the paper. The author then proposes the role of sleep and subsequently proceeds to discuss and support the claims that she makes by quoting authoritative figures in sleep research e.g. Dr. Diegel who is a head chief neurobiologist. In this article the author takes care to provide concrete evidence for the clai ms that she makes. For example, when advancing her main argument about sleep being nature’s own time management too, the author reinforces her assertions by presenting the theories of authorities in psychiatry and psychology who also are of the opinion that sleep optimizes animals’ use of time.

Get your first paper with 15% OFF Learn More However, I feel that the author provided only the bare minimum information on the other theories on the role of sleep thus presenting the reader with only to one side of the coin. In my opinion, the paper would have been more informative if it had briefly discussed the other theories so as to enable the reader to critically evaluate their validity for himself Article two In today’s world, television is almost invariably a part of our lives and trying to keep away from this prominent force is for many people an uphill task. The art icle Why We Tuned Out by Karen Springen as appearing in the NewsWeek on November 11, 2002 attempts to illustrate that shielding ones children from television is not only possible but comes along with numerous benefits. The main point advanced by Springen is that shielding children from television results in the children being more physically and mentally active. The author also contends that the children do not risk turning into misfits as a result of abstinence from television programs. I agree with these assertions by the author that television watching is detrimental to the development of children and limiting the same will result in creative and physically active children. In her article, Springen credits the lack of television watching for her daughters inquisitive and energetic nature. She goes on to illustrate that according to research, kids who watch more than 10 hours of TV each week are more likely to be overweight, aggressive and slow to learn in school. From these res earch findings, Springen justifies her imposition of a no television rule to her daughters so as to prevent them from assimilating these negative behaviors which are attributed to exposure to television. Despite these convictions, the author goes on to note that a complete restriction on television watching may result in her children missing out on good educational programming. However, the author proceeds to note that most children who watch television do not engage in the educational programming but rather favor cartoons, adventure stories and other programming which has little educational value if any. As such, Springen affirms that missing out on television all together is better than gambling on the very limited likelihood that children will watch something educational on TV. The second issue that Springen tackles is the alleged likelihood of her children turning into social outcasts as a result of her puritanical approach with regards to television. This is a fear that is acc entuated by one psychiatrist who quips that its awful to be different from the other kids in fourth grade. Springen dispels of this fears by pointing out that her children continue to enjoy products based on TV characters despite their not watching television since there exist other avenues such as books and magazines through which the children can be informed of popular culture. Advertising We will write a custom essay sample on Analyze Psychology Aritcles specifically for you for only $16.05 $11/page Learn More The author also highlights the fact that her children do not mention missing out on any of the popular programming even though they do interact with other children at school who undoubtedly mention the shows. As such, it is plausible that Springen’s children are not at a risk of turning into outcasts due to her restriction on their television watching habits. The author goes on to suggest that she may be forced to let them watch some shows w hich have a special meaning to the children. Different articles on stress Article three The article, â€Å"The Physical, Mental, Emotional and Behavioral effects of Stress† by Heather Tripp has as its central idea the expression of various adverse effects of stress not only on the mind but on the body as well. The author goes on to explicitly outline the physical, mental, emotional and behavioral effects that stress can have on a person. She also attributes the escalation of some conditions e.g. blood pressure and heart diseases to stress. The article further focuses on stress reduction and recommends various remedies to deal with stress related disorders. Tripp’s article shows a bias towards the physical manifestation of stress as is expressed through her outline of effects. Article four In the article, â€Å"The Effects of Stress on Mental Health† by Paul Hata, the mental effects that stress can manifest in a person are seen to be the major underpinning for t he article. Hata highlights on the mental breakdown tendencies that are as a result of stress. He goes on to define mental breakdown as the loss in interest or ability to function normally by a person due to mental pressure exerted on them. This can be seen to be the article’s central focus since the author shows a particular bias to the mental effects of the condition while only vaguely alluding to the other effects. Article five The third article entitled â€Å"Stress management† by the mayo clinical staff offers a more educational albeit concise reading on stress. The article has at its core the need for a person to take action thereby gain control over stress in his/her life. The article explains what stress is and goes on to articulate that stress is actually the body’s inbuilt alarm system and not its enemy as most people assume. The article focuses on ways in which one can identify and subsequently cope with stress thus highlighting control over stress as the major concept in the article.Advertising Looking for essay on psychology?

Get your first paper with 15% OFF Learn More The articles by Mayo clinic staff and Tripp attribute the long-term exposure to stress as being disruptive to most of the body’s process. As such many health problems including: high blood pressure, heart attacks, digestive problems and obesity are seen to have as their root cause stress. Both articles therefore emphasis on the need to adopt less stressful lifestyles so as to ensure physical well being of a person. While the articles do not come up with a unified set of strategies as to how to deal with stress, they all agree on the need to deal with stress. The respective authors progress to offer tips and suggestions on how to reduce stress levels. A health diet and proper sleep patterns are common tips agreed on by the three articles. The fostering of relationships is also highlighted as one of the means to deal with or altogether prevent stress. This rationale stems from the fact that man is a social creature and each encounter with others can yield to fruitful results. In cases where the stress is too progressed, professional counseling is seen as the key to offset this state and restore normality to the person. Psychological perspectives in the analyzed articles As mentioned earlier, psychology is a matter of studying behaviors. Therefore, for any issue to qualify as a psychological topic it must contain clear variables (fixed and dependent) and theoretical backing that explains the connection between the variables, as well as how they affect each other. In regards to the first article (Sleep May Be Nature’s Time Management Tool), the author tries to establish the connection that exists between sleep and time management. The second article (Why We Tuned Out), the author explains the effects of television to the physical and psychological development of children. In the last three articles, the authors try to show how stress affects various aspects of our lives. Conclusively, the presence of these attributes in all five articles is what ma kes the issues discussed psychological. Carey, Benedict. Sleep May Be Nature’s Time Management Tool. 2009.

6 Kinds of Simple Machines

6 Kinds of Simple Machines Work is performed by applying a force over a distance. These six simple machines create a greater output force than the input force; the ratio of these forces is the mechanical advantage of the machine. All six of the simple machines listed here have been used for thousands of years, and the physics behind several of them were quantified by the Greek philosopher Archimedes (ca. 287–212Â  BCE). When combined, these machines can be used together to create an even greater mechanical advantage, as in the case of a bicycle. Lever A lever is a simple machine that consists of a rigid object (often a bar of some kind) and a fulcrum (or pivot). Applying a force to one end of the rigid object causes it to pivot about the fulcrum, causing a magnification of the force at another point along the rigid object. There are three classes of levers, depending on where the input force, output force, and fulcrum are in relation to each other. The earliest lever was in use as a balance scale by 5000 BCE; Archimedes is credited with saying Give me a place to stand and I will move the earth. Baseball bats, seesaws, wheelbarrows, and crowbars are all types of levers. Wheel Axle A wheel is a circular device that is attached to a rigid bar in its center. A force applied to the wheel causes the axle to rotate, which can be used to magnify the force (by, for example, having a rope wind around the axle). Alternately, a force applied to provide rotation on the axle translates into rotation of the wheel. It can be viewed as a type of lever that rotates around a center fulcrum. The earliest wheel and axle combination known was a toy model of a four-wheeled cart made in Mesopotamia about 3500 BCE. Ferris wheels, tires, and rolling pins are examples of wheels and axles. Inclined Plane An inclined plane is a plane surface set at an angle to another surface. This results in doing the same amount of work by applying the force over a longer distance. The most basic inclined plane is a ramp; it requires less force to move up a ramp to a higher elevation than to climb to that height vertically. No one invented the inclined plane since it occurs naturally in nature, but people used ramps to build large buildings (monumental architecture) as early as 10,000–8,500Â  BCE. Archimedess On Plane Equilibrium describes the centers of gravity for various geometrical plane figures. Wedge The wedge is often considered a double inclined plane- both sides are inclined- that moves to exert a force along the lengths of the sides. The force is perpendicular to the inclined surfaces, so it pushes two objects (or portions of a single object) apart. Axes, knives, and chisels are all wedges. The common door wedge uses the force on the surfaces to provide friction, rather than separate things, but its still fundamentally a wedge. The wedge is the oldest simple machine, made by our ancestors Homo erectus at least as long ago as 1.2 million years to make stone tools. Screw A screw is a shaft that has an inclined groove along its surface. By rotating the screw (applying a torque), the force is applied perpendicular to the groove, thus translating a rotational force into a linear one. It is frequently used to fasten objects together (as the hardware screw and bolt does). The Babylonians in Mesopotamia developed the screw in the 7th century BCE, to elevate water from a low-lying body to a higher one (irrigate a garden from a river). This machine would later to be known as Archimedes screw. Pulley A pulley is a wheel with a groove along its edge, where a rope or cable can be placed. It uses the principle of applying force over a longer distance, and also the tension in the rope or cable, to reduce the magnitude of the necessary force. Complex systems of pulleys can be used to greatly reduce the force that must be applied initially to move an object. Simple pulleys were used by the Babylonians in the 7th century BCE; the first complex one (with several wheels) was invented by the Greeks about 400 BCE. Archimedes perfected the existing technology, making the first fully-realized block and tackle. Whats a Machine? The first use of the word machine (machina) in Greek was by the ancient Greek poet Homer in the 8th century BCE, who used it to refer to political manipulation. The Greek playwright Aeschylus (523–426 BCE) is credited with using the word in reference to theatrical machines such as the deus ex machina or god from a machine. This machine was a crane that brought actors playing gods onto the stage. Sources and Further Reading Bautista Paz, Emilio, et al. A Brief Illustrated History of Machines and Mechanisms.

Commercial law case study Example | Topics and Well Written Essays - 1750 words

Commercial law - Case Study Example If the defendant fails to come up to the customary, this will be a violation of the duty of care as judged by reference to the following factors: What did the defendant know? This is to say that, the defendant will only be legally responsible if the reasonable person would have foreseen the loss or damage in the circumstances prevailing at the time of the alleged breach of duty. Secondly, the degree of jeopardy of the situation. The bigger the risk that severe harm can be brought by, the greater the safety measures that the defendant will be required to take (Jance, 1999). This is to say the when the risk involve is of little magnitude, the plaintiff is required to take his or her own precautions and any claim of breaching of duty that will be presented by the plaintiff will be overlooked. However, when the risk is of greater magnitude, the defendant will be liable. Thirdly, is the communal significance of the defendants doings. If the defendants actions give out a socially useful function then they may have been justified in taking greater risks. Lastly, a defendant complying with a general practice in his area of activity w ill usually be well thought-out to have met the standard of a reasonable man, except the court judges the practice itself to be negligent (Bradgate & Savage, 1991). In order for John to establish a breach of duty by the Willow Council, carried out himself as a responsible and reasonable person. However, John, who had drunk too much champagne, was conducting his activities in an open space where everyone could see him. He got out of a car and dared his to friends, Mason and Janice, to climb over a two meter fence, that prevented people from going beyond it, and walk to the edge of the cliff. His friends refuse but John climbs over the fence and walk to the edge of the cliff. He loses balance, fall off and breaks his leg. A court analyzing these particulars will apply the

There is no such thing as a neutral question. Evaluate this statement Essay - 3

There is no such thing as a neutral question. Evaluate this statement with reference to two areas of knowledge - Essay Example For instance, â€Å"Why do you think he is leaving the company?† This is apparently a neutral question since the best answer is obviously known to the person who is leaving the company. The questioner’s interest is superficial or mere curiosity or else the question would have been placed with the person concerned. In the most elementary form, neutral questions are those which are asked by innocent children who express their curiosity over anything they see or hear. Questions like â€Å"From where does babies come?† are common neutral questions since the children who frame these questions do not have any pre-conceived notions and can be satisfied by any random answer. In such cases, the questioner, i.e. the children have no inherent interest in the questions other than curiosity. Since, as already explained, in a case of a neutral question there is no apparent interest in the mind of the questioner therefore such questions are generally unemotional and open. However, this paper is concerned with the statement that there is no such thing as a neutral question. In the sociological perspective, the weight of a question is determined by the social context, i.e. answers can vary depending on whom the question is targeted. Therefore, â€Å"a sociologist who does not subject his own questioning to sociological questioning will be incapable of making a truly neutral sociological analysis of the answer it receives† (Bourdieu, 41). In the realm of science, knowledge is based on real questions with concrete and experimentally proven answers. A question cannot be neutral since the questioner expects a pre-conceived answer, i.e. a hypothesis based on which his future work will be constructed. The most critical aspect of scientific knowledge is that a scientist can ask a question of whys and hows for the reason that he will be seeking an explanation for his question. Now, the question remains whether in science it is
