Fuzzy logic in car safty

Car safety issues are wide-reaching problem. This problem is mainly due to human driving which involves reaction times, delays, and Judgment errors that may affect traffic flow and cause accidents. In some cases, the cause of the accident is distraction on the part of the driver and failure to react in time. Even in some cases, it could be cause by environmental factors (Song, 2005). Advanced system of auxiliary functions has been developed to help avoid such accident and minimize the effects of collision should one occur.Fuzzy logic provides tools for dealing with imprecision, which is fundamental to many engineering problems. The level of safety in our society could be archived by applying fuzzy logic control system. Fuzzy logic control technique has become an active area of research in the application of industrial processes, which are not friendly to straight control techniques. It attempts to emulate human mind for checking the processes parameters and to take decisions regardin g the control action (Eugene, 1985).Fuzzy control become a huge industry in Japan and other countries where it was adapted into home appliances such as scum cleaners, microwaves ovens, video cameras, washing machines, etc. A fuzzy controller acts or regulates by means of rules in a more or less natural language, based on the distinguishing feature: fuzzy logic. On the other hand, to reduce car accidents we are going to examine a system, which makes the drivers, pay more attention and alert them before an accident takes place.Because of this, we shall acknowledge the digital systems because they are easier to handle with, so the first thing in the development is to convert all variations in the car environment into digital signals without any changes. The ultrasonic transmitter circuit sends its vibrations in front of car, when these vibrations reflected the ultrasonic receiver circuit would take these vibrations and amplify it. Moreover, send it to the microelectronic, which can com pute the distance between the car and anything in front it (as shown in the figure 1 below).At the same time, the Infrared ‘R) circuit senses the round of the wheel and sends it signal to the microelectronic, which can compute the car speed. After that, the microelectronic sends the output signal to the speaker and The LCD. In addition, of these output devices the microelectronic sends output data to a personal computer using the serial port. Figure 1: Overview of the used hardware; copied figure (from Journal of Computer science 4 (1 2): 1061-1063, 2008]) We shall consider developing level of safety under three steps, which are: Defining level of safety Calculating each degrees of risk between two vehicles, and Combining these degrees to level of safety with average speeds in some divisions (Method et al, 2001). In the other hand, to ascertain the danger degrees of each car, and the base elements, fuzzy sets and their membership functions, are define by using survey data and degrees of risk (Chunk, 2003). In addition, if-then rules of inference engine are made by rough set theory.Conclusively, to get the level of safety in some divisions, fuzzy membership function values of each safety result is averaged, and a method to et ‘Level of Safety based on these degrees relates with an average of safety speeds is suggested. Definition of Level of Safety Safety being a wide-reaching problem, has gained various definitions from several authors. The level of safety in a road division means the grades, which people feel about the possibility to experience, rear-end collision including relentlessness in the division (Song, 2003).This definition is composed of three elements related with roads in themselves, driving behaviors in this road, and relation between drivers and roads. These three factors are mix in microscopic driving behaviors on roads, and five gyroscopic traffic condition variables are selected such as velocity and acceleration of lead and follow ing cars, and the gap distance between these cars divided the minimum safety distance (Method et al, 2001). The minimum safety distance (MS) is the distance that following car needs to avoid a rear-end collision.The traffic condition in itself can be included into velocity, drivers' behaviors are able to be included into oscillations of accelerations in every two seconds, and degree of risk in the system can explain the gap distance divided the minimum safety distance (MS). Where, : following Car speed Response time : Possible deceleration rate However, these results are not level of safety but risk degrees of two Cars (Fuller, 2005). Definition of Fuzzy Sets and Membership Function The member functions are divided into speed fuzzy sets and acceleration fuzzy sets (Method et al, 2001).Speed fuzzy sets are composed of three sets, ‘high speed', ‘medium speed', and ‘low speed'. Their membership functions are based on macroscopic traffic condition data and number of ac cident. Acceleration fuzzy sets also consist of three sets, ‘positive acceleration', ‘no acceleration', and ‘negative acceleration', and membership functions, which are based on microscopic field, survey data and maximum and common acceleration rates of vehicles. The gap distance/MS sets are divided into three fuzzy sets, ‘more than 1', ‘around 1', and ‘less than 1' using microscopic data.The combined danger degrees are about from 0. 4 to 0. 55 that corresponds to common situation defined in fuzzy set, and this result means that people drives more or less safely bearing some anger because there are possibility to happen accidents in traffic condition in itself but drivers believe that they can response properly to a danger situation. Moreover, this result shows that there are some danger situations n each two vehicle, but in road divisions, the danger degrees become normalized.Figure 3: Relation between Speed and Danger Degrees For this reason, â €˜Level of Safety should not include the combined danger degree directly, and should be deducted from relationship between speeds as well as danger degrees. In order to find their relation, pairs of average speed and danger degree are, shown in figure 3. We find that danger degrees are low in low speed level and high in fast speed level, and the level of change is not high in low and rapid speed situations. However, in medium speed case, danger degrees are increase vapidly, and there are two points of inflection.If danger degrees do not change rapidly, drivers would react properly because their expectations to the road conditions are fixed, but if they change fast, the situation on a road division would be dangerous because the expectation of drivers cannot be fix. Consequently, the simple possibility of accidents depends on the grades of change in danger degrees, and the severity depends on the quantity of danger degrees. Conclusively, this seminar suggests ‘Level of Safet y such as in Figure 4. First, range of Level of Safety in which relentlessness and possibility of accident is high is defined as Very dangerous situation', E.Similarly, that of range which relentlessness or possibility is high is suggested as ‘dangerous situation', D, and which relentlessness and possibility is usual as ‘common situation', C, and which possibility is low and relentlessness is high as ‘safe situation', B, and which possibility and relentlessness is low as Very safe situation', A, these are shown in Table 3 below. Finally, relation of danger degrees and average speeds develops the intercepts of each level of safety, UT it needs to be more precisely define by further study based on more investigation.Table 3: Level of Safety Definition The possibility The severity The range(km/hrs) Very safe -18 c 25-40 (or) High 18-25, 40-53 53-63 Figure 4: copied figure (from [Proceedings of the Eastern Asia Society for Transportation Studies]) 8. 0 CONCLUSION This seminar work shows how the system provides a solution to decrease the car accidents by giving the drivers more time to avoid the accidents. Adjusting the sensitivity and the accuracy for the measuring circuits is important to ensure that the assured parameters represent its actual values.The use of microelectronic makes it possible to implement the system with less hardware components. The microelectronic, FISTICUFF was chosen among all the other microelectronics because of its low-cost and small size. In addition, we evaluated safety degrees on a road division, and suggest ‘Level of safety. The method to develop ‘Level of Safety from degrees of danger and combined using fuzzy theory, and we combined danger degrees to define level of service with average speeds. This is the first trial to define

Russia Superstitions

Customs that are more often regarded as superstition Mothers typically do not show their baby to anyone except the father, the midwife and other close relatives for forty days after the baby is born. Many nationalities have a set of rituals for the guests that they have to follow to see the baby for the first time. [1] Before leaving for a long journey travelers, and all those who are seeing them off, must sit for a moment in silence before leaving the house. It is often conveniently written off as a time to sit and think of anything one may have forgotten. 2] After someone has left the house on a long journey, their room and/or their things should not be cleaned up until they have arrived, or at least a day has passed if they are guests in a house. [2] Knocking on wood is practiced in Russia as in other countries. However Russians tend to add a symbolic three spits over one's left shoulder (or simply with the head turned to the left), and Russians will often knock three times as wel l. Traditionally one was spitting on the devil (who is always on the left). 3] Breaking a mirror is considered bad luck in Russia, as is looking at one's reflection in a broken mirror. The effect is also more severe than 7 years of bad luck (as in American culture). [4] On examination day, it is bad luck to make your bed, wear anything new, or cut your fingernails. [3] It is bad luck to use physical hand gestures to demonstrate something negative using oneself or someone else as the object. For example, when describing a scar you saw on someone's face you should not gesture on your own face or someone else's. If you must, you can demonstrate in mid-air.If one does it without realizing, it can be countered by making a hand motion towards the body part used and then an abrupt motion away (as if to pick up the bad energy and throw it away). [3] If one person accidentally steps on another person's foot, it is common for the person who was stepped on to lightly step on the foot of the pe rson who stepped first. It is said that they thus avoid a future conflict. [3] Birthday parties should be celebrated on or after one's birthday, not before. So when one's birthday falls during the week, it's best to celebrate the following weekend. And never give someone birthday wishes before their birthday. 3] Talking about future success, especially boasting about it, is considered bad luck. It is considered better to be silent until the success has been achieved or to even sound pessimistic. [3] Returning home for forgotten things is a bad omen. It is better to leave it behind, but if returning is necessary, one should look in the mirror before leaving the house again. Otherwise the journey will be bad. [4] Many Russians consider giving sharp objects, like knives or scissors, as gifts, to be taboo. You can avoid this taboo taking symbolic little money, for example one Russian ruble, in exchange as if it is a trade, not a gift. 4] Birds that land on a windowsill should be chased away. If they tap on the window, or fly into it (open or closed) it is considered a very bad omen (often of death). [5] If a chicken crows at you three times before noon, the death of a close family member can be expected within a fortnight. The chicken should be killed, but not eaten, as consuming it will bring about further misfortune. [5] Things bought for a newborn baby (such as clothes, toys, furniture, etc. ) should only be purchased after the baby is born. This is usually done in a big hurry. 1] It is often considered taboo to step over people, or parts of their body, who are on the ground. It is often said that it will prevent the person from growing (if they are not fully grown already). It is better to politely ask the person to move or to find a way around them. If one accidentally steps over a person (or people), it is sometimes standard to step backwards over them. [3] Unmarried people should not sit at the corner of the table. Otherwise they will not marry. This mostly applies to girls, and often only young girls. Sometimes it is said that you will not marry for 7 years, making it all right for young children to sit there. 6] When giving an animal as a gift (a cat, dog, bird, etc. ), the receiver should give the giver a symbolic sum of money, for example one Russian ruble. [5] A purse (or any other money holder) as a gift requires a little money inside. Given empty it causes bad financial luck. [4] A funeral procession brings good luck. But one should never cross its path or it is bad luck. [7] A woman with empty water buckets coming towards you is considered a bad omen. [3] A group of two or more people should not talk on different sides of a tree. They should all keep to one side or the other. [3] Bread should only be cut with a knife, not with your hands.Otherwise, it is said, that your life will be broken. The opposite is held true by some people. [4] Two or more people should never use one towel at the same time to dry their hands or bodies, or it is said to bring conflict. [4] A stranger should not look at a newborn baby before it is a certain age (between two months and one year). If one looks at the baby it is considered bad luck to compliment it. Instead, one could say, â€Å"Oh, what an ugly child! â€Å". [1] It's good luck to trip on your left foot. [3] One should never hand a knife directly to another person, as it is said that the two will get into a fight.Instead a person should always place the knife down on a surface, and only then can the other person pick it up. In several cases you can give it directly, but only pointing the sharp end to yourself and making the knife's handle accessible for the opposite person. [4] If one feels that he or she may have been cursed by someone (had the â€Å"evil eye† put on them) or just has the feeling of a hostile presence, it is recommended to remove one's coat and then put it back on starting with the hand opposing the usually used one. It is also recommended to pin a French Pin inside your clothing to avoid the curse of the evil eye in the first place. 3] One should not to shake hands or give something through a threshold. [3] Whistling in a house would bring misfortune to that household (see origins below). It is considered taboo to give something that is broken or has a defect as a gift. Before one takes an exam, someone else would say, â€Å" ! † which roughly translates to â€Å"neither fur, nor feather! † which means good luck. To this, the one taking the exam would reply, â€Å"? ! † which means, â€Å"Go to the Devil! † or â€Å"To the Devil! † which is a way of securing good luck

Sarbanes-Oxley’s Act: Article Summary

The article â€Å"Congress Should Repeal Sarbanes-Oxley Act† by William Niskannen discusses reasons and arguments why the law should be annulled. The Sarbanes-Oxley Act (SOA) was passed, in 2002 and was considered a response to the collapse of Enron and other corporations with similar problems. Nevertheless, the author views this act as inadequate, harmful and unnecessary. Firstly, the act is viewed as unnecessary because â€Å"the stock exchanges had already implemented most of the SOA changes in the rules of corporate governance in their new listing standards†. p. 12) In other words, Exchange Commission is provided with full authority to enforce and to approve all accounting rules and standards, as well as to control financial statements of their firms. Furthermore, Department of Justice is able to prosecute executives for frauds associated with securities, stocks and bonds. The author claims that Public company Accounting Oversight Boards isn’t useful as it ha s no authorities to regulate remaining independent public auditors. Secondly, the law is viewed as harmful because it â€Å"substantially increases the risks of serving as a corporate officer or director†. (p. 13) The author means that SOA may serve more foreign and small firms, rather than stocks on American exchange. For example, the law suggests banning of loans to corporate officers and it leads to elimination of one of the most effective tools of executive compensation. In such a way, the act reduces incentives of directors and corporate executives to receive legal advice. Finally, the act is viewed as inadequate because it has proved to fail problems of accounting, taxation, corporate governance and auditing. In such a way, SOA increase the risk of bankruptcy. I think that the question whether SOA is effective or should be repealed is rather controversial. On the one hand, it cares for of foreign firms and small businesses, as well as fails to respond to auditing and taxing problems. On the other hand, it is designed as rescue program after Enron scandal. Its goal is to restore reputation and public trust in corporate sector in the USA.

Modelling and Simulation of engineering systems Essay

Modelling and Simulation of engineering systems - Essay Example The main advantage of SIMULINK over other programming softwares is that, instead of compilation of program code, the simulation model is built up systematically by means of basic function blocks. Through a convenient graphical user interface (GUI), the function blocks can be created, linked and edited easily using menu commands, the keyboard and an appropriate pointing device (such as the mouse). A set of machine differential equations can thus be modelled by interconnection of appropriate function blocks, each of which performing a specific mathematical operation. Programming efforts are drastically reduced and the debugging of errors is easy. Since SIMULINK is a model operation programmer, the simulation model can be easily developed by addition of new sub-models to cater for various control functions. As a sub-model the induction motor could be incorporated in a complete electric motor drive system (Wade 495-505; Shi 231-235). A generalized dynamic model of the induction motor consists of an electrical sub-model to implement the three-phase to two-axis transformation of stator voltage and current calculation, a torque sub-model to calculate the developed electromagnetic torque, and a mechanical sub-model to yield the rotor speed. In addition, a stator current output sub-model is needed for calculating the voltage drop across the supply cables. Multiple line equation(s) cannot be represented in ASCII text... ASCII text where Vas, Vbs, and Vcs are the three-phase stator voltages, while Vds and Vqs are the two-axis components of the stator voltage vector Vs. Torque sub-model of induction motor In the two-axis stator reference frame, the electromagnetic T is given by:T = PLm/3(idriqs - iqrids) Mechanical sub-model of induction motor From the torque balance equations and neglecting viscous friction, the rotor speed omega0 may be obtained as follows: Multiple line equation(s) cannot be represented in ASCII text where J is the moment of inertia of the rotor and load and TL is the load torque. Stator current output sub-model The stator current output sub-model is used to calculate the stator current amplitude according to the following equation:|is| = 2/3 square root of (ie, sub ds)2 + (ie, sub qs)2 A SIMULINK Fcn' block is used to implement the above equation. Simulation System Of Induction Motor The complete simulation system of the induction motor includes the induction motor model in a power supply sub-model. Power supply sub-model The voltage supply block consists of a three-phase sinusoidal voltage generator and a terminal-voltage calculation block which accounts for the voltage drop in the supply cable. Simulation Results The induction motor chosen for the simulation studies has the following parameters: Type: three-phase, 7.5 kW, 6-pole, wye-connected, squirrel-cage induction motorRs = 0.288 OMEGA/ph Rr = 0.158 OMEGA/ph Ls = 0.0425 OMEGA/ph Lm = 0.0412 OMEGA/ph Lr = 0.0418 OMEGA/ph J = 0.4 kg m2 JL = 0.4 kg m2 To illustrate the transient operation of the induction motor, a simulation study of direct-on-line starting is demonstrated. At t = 0, the motor, previously

Portrait of a Teacher Personal Statement Example | Topics and Well Written Essays - 750 words

Portrait of a Teacher - Personal Statement Example One particular past educator of mine singlehandedly embodied the teaching philosophy found within each â€Å"portrait of a teacher.† During my time spent in this classroom, I was able to feel a sense of belonging and purpose. Incorporating a student-centered instructional approach, as well as diverse assessment approaches, this particular educator fostered a learning environment where each and every student felt the driving purpose and moral of each lesson. Throughout the course of the year, the instructor cultivated learning through student interaction, as well as life-relevant lessons, which afforded each pupil a meaningful and unique learning experience. Although the educator incorporated the use of direct-instruction into the classroom setting, the majority of learning activities centered around student interaction and engagement, which allowed each student the opportunity to learn on their own, while the teacher played the role of the facilitator, rather than the dictator . Students in the classroom felt encouraged to think critically about a topic or lesson because they felt a connection to the instructor’s material, and no longer felt like an inanimate object in the classroom. The democratic feel to each classroom activity permitted students to express themselves through their artistic and personal strengths, and also led to peer interaction that was absent from most classroom settings. In contrary to this particular teacher, another instructor from my past lacked the fundamental qualities of an influential educator. Rather than promoting a democratic principal in the classroom setting, this particular teacher followed a more totalitarian approach to education. Thinking back to this classroom, I struggle to recall meaningful lessons or memorable moments. Instead, I can recall a sense of fear and anxiety, which ultimately restricted my ability to learn and develop as a student. The lack of peer interaction in the classroom, as well as the tea cher-centered instructional approaches, cultivated an inability to focus on the task at hand, and inevitably led to poor student retention and understanding. One specific instance I can recall from this learning environment, which illuminates this exact point, was during a test review lesson. During review, the teacher would simply instruct students, through direct instruction, of the material that would be covered on the future exam. Instead of utilizing a student-centered approach, which would have ultimately encouraged student interaction and promoted discussion on the topic of review, the teacher simply lectured on the main points of the test. I can still recall the feeling of being unattached to the curriculum, simply worrying about the results of the exam, rather than the process of learning or the enjoyment of being a student. Inevitably, this led to poor test results, as well as a lack of enthusiasm for education. As a future educator, my goal is to incorporate a sense of be longing and purpose within each and every student. From my experiences as a student, I can still recall the detrimental impact of feeling neglected or ostracized from the process of learning. Author, Robert Slavin, discusses the impact on learning when students are neglected within the learning process. Slavin writes, â€Å"

Golf - Article Example Aside from which, they are the ones who do not infrequently participate in golf tournaments, hoping to bag another trophy home on a warm & sunny Sunday. There are also what you call â€Å"recreational† golfers that are a bit competitive and at the same time plays the sport to meet new people, pass time or perhaps pave their own entrance to a certain kind of clique that being a golfer suggests. The last type would be the first-timer golfers who were probably tagged along by one of their friends who plays golf or perhaps those that tried the sport just so they can check another off of their bucket list. Indeed, golf is one many splendored thing and the best thing to do before one starts to play golf would be to know why you want to play golf and what is it that you expect from the sport. This is because getting into it does not only change the environment you are in but most importantly can change your life. This is because allowing something new in your life would mean being open to changes in your activities, mindset & attitude. Just like life, with golf, you can expect anything under the sun and with the right expectations comes a disappointment-free

H.W Assignment Example | Topics and Well Written Essays - 250 words - 3

H.W - Assignment Example This paper will discuss whether it is ethical for managers to control their employees. The major role of a manager is to coordinate the team of employees so that they achieve the organizational goals. Human beings have a nature of working under pressures, and hence, every manager must ensure that the employees have certain set goals. Setting goals for employee is ethically acceptable in business management as it is a measure to maximize productivity. The managing director has the role of ascertaining that his/her employees are working to the required standards and hence must control their mode of operation (Snell, & Bohlander, 52). Controlling the employees to ensure that they deliver work and service of a high standard is ethical and is not a form of exploitation. However, some managers tend to overload their employees with duties that are not meant for them. In such cases, managers are exploiting their employees and it is unethical as per the management codes of practice. Reward programs are meant to be a form of motivation to the employees by ensuring that there are happy at their workplaces (Snell, & Bohlander, 47). However, some managers set extremely high levels of production in order for their employees to receive the rewards. Such acts are a form of manipulation to employees. In conclusion, the function of a manager is to control and coordinate the other employees and hence it is not a form of

Prostate Essay Example | Topics and Well Written Essays - 500 words

Prostate - Essay Example Similarly, diabetes cases are at an amazing. Though there is no apparent relation between prostate cancer and diabetes. However, recent research has shown that type 2 diabetes cases in men often lead to prostate cancer . "These distressing numbers show how important it is to prevent type 2 diabetes since there is a slight chance of diabetics developing prostate cancer," said Ann Albright, director of the diabetes translation division at CDC, in a statement. "We know that a structured lifestyle program that includes losing weight and increasing physical activity can prevent or delay type-2 diabetes." Available data suggests that the prostate cancer rates have shot up greatly since 2008 to about 20 percent. If this trend continues, nearly a fifth of the entire male U.S. population will eventually be ailing. At the moment, 8.3 percent of all Americans, and 11.3 percent of people over the age of 40, now have the disease. What is even more alarming is that 27% of patients are not even aware of their condition. If we closely assess the trend, we find that the rates of prostate cancer in America are expected to rise further in the years to come . There are many risk factors for prostate cancer. These include alcohol intake, high blood pressure, obesity, lifestyle changes, eating unhealthy foods especially high-fat diets and high fat levels in the blood. Ethnicity is also a major contributing factor for prostate cancer. Certain groups have a greater risk of developing prostate cancer than non-Hispanic whites. They include which include as Native Americans, Hispanic Americans, African Americans, and Japanese Americans. Another risk factor is aging. At a later age of 45, the risk for prostate cancer begins to rise substantially. However, the risk is higher at the age of 65. Apart from physical lifestyle changes, natural medicines like almonds and green leafy vegetables exist. These help to prevent and treat prostate cancer when added into the diet. Together with

Multiculturalism issues and economic-based solutions Essay

Multiculturalism issues and economic-based solutions - Essay Example It was expected that the global economic extension will bring stability and development in the local markets. But the result is entirely reverse and critics are viewing the globalization as another form of colonial imperialism. Political instability due to corrupt leaders, lack of proper infrastructure favorable to rich countries causes brain drain from less privileged countries. Immigration is the leading issue in rich countries who are reviewing their existing laws to make it difficult for inter-state migration. Also for those who have already migrated to one of the countries with better prospects, the hosts will have to initiate programs to adjust such individuals without disturbing the existing coherence in the society. Immigration is causing another issue of individual and organized racism against settlers. Educational, economical, social, and political racism has plagued the idea of equality in different communities across the globe. Goldring argues that civil forces and campai gns can bring a positive change through community rebuilding based upon justice, equality, freedom, tolerance, mutual respect, and basic human rights that guarantees one’s participation in the process of decision–making in social, economic and political life.

(poverty)socio-political factors influencing the mental health of an Essay

(poverty)socio-political factors influencing the mental health of an individual - Essay Example Poverty has a significant influence on physical and mental health. This paper presents a critique of the impact of poverty on the mental health of an individual. Poverty is strongly associated with social inequalities in the society. According to Nettleton (2006), unequal distribution of income leads to the emergence of a gap between different income groups yet such groups require the same basic needs. The underprivileged group suffers psychosocial anxiety that contributes to weakening health and death in case of prolonged stress. Poor social and physical infrastructures result in poor community health and mortality especially among the lowest social economic groups in such communities. In spite of stress, poor communities suffer frustration and unstable families and often exhibit tendencies towards domestic violence, criminal activities such as theft, murder and rape. These antisocial behaviors are also experienced in higher income groups but at a lower rate (Dalton et al. 2007). In one of my clinical placements I met a client named John who’s came from a poor neighborhood. He was worried about insecurity and was stressed after his d aughter was sexually assaulted by three young men. Hearden (2008) argues that the poor are exposed to hazardous environments and even when in employment are engaged in stressful, unfulfilling and depersonalizing activities. For example, John worked as a casual laborer in a skin tanning firm which was the only alternative available after his shop run out of stock as a result of rising cost of living that made him use part of the goods to feed his family of six. Such people often have no access to the essentials and services of life and are also subjugated by the main stream social class that is better informed regarding mental health. The poor are among the minority groups whose mental health is at risk due to the tendency to

Technology Leads to Positive Social Changes Essay

Technology Leads to Positive Social Changes - Essay Example It has been apparently observed that previously people had to make more efforts in order to perform a simple work. However, the notion of technology made the humans’ job easier as well as simple and reduced their work-related difficulties at large. It is in this context, social changes can be defined as the shifts in human attitudes as well as behaviors that differentiate society in an effectual manner. Advancement in technologies significantly made positive changes in the social aspects. In this regard, technology provides certain advanced means that helps to improve the human attitudes as well as behaviors within the social context in a positive manner (Kubesh, Katie, Mcneil, Niki, and Bellotto, Kimm 10). Thesis statement This discussion intends to critique the proclamation that the aspect of technology certainly gets better over time and always lead towards positive social changes. Evolution of Technology over Time and Its Relation to Positive Social Changes Technology is r egarded as the process that makes a significant effort in meeting the human requirements such as shelter, food, health as well as communication. Advanced technologies have been getting better over a period of time that intends to provide significant facilities with the intention of improving the society. It can be affirmed that the idea of technology has developed the living standard of the societal members to a greater extent throughout the last decade and is still continuing to perform such function. It has been apparently observed that technology has provided advanced amenities to different people belonging to any communities by the systematic employment of science. Previously, social interaction among the people living in different regions was viewed to be quiet due to lack of communication as well as interaction. However, in recent days, with the introduction of innovative technologies such as mobile phones and internet, people can interact with each other quickly without facin g any difficulties. In the past, the distance was considered to be one of the critical factors that restricted social interaction among people.

Employment Law and HRM Strategy Essay Example for Free

Employment Law and HRM Strategy Essay Employment laws play a critical role in human resources management strategies and in an organization operation. Employee laws are design to protect the employees by the Equal Employment Opportunity Commission (EEOC). The Equal Employment Opportunity Commission (EEOC) â€Å" federal enforcement agency enacted to ensure that employers follow and abide by rules set forth in the Civil Rights Acts of 1964†(Web Finance, 2012). However, the act insisted of â€Å"people should be given the same opportunities and equal changes to obtain employment regardless of their color, race, gender, national origin, or religion† (Stewart Brown, 2012, pg. 0). After researching the employment laws of Georgia by visiting ga. gov and after inserting â€Å"employment laws,† the research will give a descriptively analysis of a description of a scenario that will correspond with the employment law provide. Next the analysis will describes a recommended plan to manage the HRM situation within the confines of the law. Third, the approach will be justified by the scenario to HR management. Fourth, the analysis will describe a competitive advantage may be gain by ensuring HRM practices meet the necessary employment laws. Final, a speculation will be made with an assumption of the situation was not handled in accordance with the appropriate employment laws. ? Description of the scenario that corresponds with employment law: The scenario that was beneficial compliance with the Georgia Employment Law is â€Å"disciplinary action training for supervisors of diverse employers. † The current state that analysis was research of the state of Georgia and the informative information that was providing from www. ga. gov.  Georgia’s employment laws and the HRM strategies are in compliance with the state’s regulations. However, Georgia is considering as an at-will provision. Meaning which the employers have the right to â€Å"freely discipline or discharge employees provided that the adverse employment action is not motivated by any discriminatory intent or administered in a discriminatory manner†(Morris Manning Martin, 2012). When an employer is actively training for supervisors o f diverse employers the same Equal Employment Opportunity (EEOC) guidelines are applied throughout the training. Employers have to determine when terminating or have to discipline an employee to comply within the state’s laws by not violating the federally protection classes that is consist of age, race, national origin, religion, sex, or other status. If these actions are violating the individual(s) have the right to suit the organization. However, just last month the Equal Employment Opportunity (EEOC) requested that all employers review their anti-harassment and anti-discrimination policies. Reason being, the† Equal Employment Opportunity Commission (EEOC) issued some serious concerns to the employers in an afforded to reiterate its commitment to justice from vulnerable individuals† (Flahardy, 2012). The reason for the request for the Title VI and the ADA applicants was concerns from a previous case that was review in the courts. The 6th Circuit rules that counseling recommendation violated the ADA† (Byrne, 2012). The action suit was proceed after an employee by the named of Emily Kroll’s suited White Lake Ambulance, for counseling constitutes a â€Å"medical examination,† under the Americans with Disabilities Act (ADA). Emily Kroll was employed with the emergency medical technician at the White Lake Ambulance Authority (WLAA), in which Whitehall, Mich. , in 2003 (Byrne, 2012). However, her supervisors initially considered her to be good employee until, a personal affair occurred when her marriage with a coworker failed. Krolly’s supervisor concerns grown after; Krolly and a colleague proceed into an argument and Krolly fail to administer oxygen to a patient. Krolly’s supervisors asked her would she attended counseling sessions whereas, Krolly’s supervisors claimed that they did not specific an exact theory. Emily Krolly refused the counseling and proceeds to resign from her position. Thereafter, Krolly proceeded to file suite with White Lake Ambulance (WLAA), claiming that â€Å"her supervisors† request that she obtained counseling violated under the act â€Å"Americans with Disabilities Act (ADA) (Byrne, 2012). Description of a recommendation plan that concerns HRM situation: Human Resources Management (HRM) is a critical part of an operational organization. Human Resources Management (HRM) is an organizational fundamental that deals with issues related to people such as: hiring, termination, performance organization development, training, benefits, and ompensations. However, when proceeding to make recommendations; although process has to be plan out that will incorporate certain situations and thoughts for future objectives and goals that need to be obtained within the confining of the law. However, in the case analysis, the first recommendation should have been Krolly’s supervisor should have directed her to the Human Resource Division when Krolly’s supervisor became aware of Krolly’s workplace behavior begin be problematic following an affair of a coworker. After this incident, another recommendation would be extra training courses such as: extra training courses related to the current incident, employers, and employees relationship, patients awareness. Included within the extra training courses, the Human Resources Division have to comply with the State or Federal laws and compliance with Title VII, of 1964 civil right Act. Also included in the training, the Human Resources Division should review employee’s handbook with the entire staff. Justification of the HR management’s scenario: The approach of justifying the Human Resource Division’s scenario, request for the entire staff to proceed to an important meeting. Within the meeting, the Human Resource Manager will take the approach of outlining the key elements of the importance for the meeting. The HR manager will review the current laws of Title VII, of 1964 and how it coheres with the organization’s policies and procedures. The HR manager will address to the managers and employees that the organizations have to stay within comply of the rules and regulations of the organization. The HR manager will have to address related important information that would pertain from the previous incident. The HR manager also has to address to each individual, if questions or concerns developed throughout the training; the manager will suggest to the employees, to address any concerns or questions that may develop throughout the training. Final, the HR manager will be addressed to the staff, at the end of the training session; an agreement document will have to be sign, stated that all individual understood the reason for the extra training course. Description of a competitive advantage of ensuring HRM practices: A competitive advantage of ensuring HRM practices that meet the necessary employment laws would depend on how efficiently the HRM division within the organization?

Ban Chiang Culture And Dong Son Culture History Essay

Ban Chiang Culture And Dong Son Culture History Essay For the origin of the metalwork in Southeast Asia, there were many different opinions of the scholars. Some scholars support that the metalwork in Southeast Asia was origin locally and some of them support that it was from India and China. But unluckily, there is not enough evidence to prove which of them would be the truth. Therefore, the origin of the metalwork in Southeast Asia is not clear and uncertain. Compare with the Ban Chiang culture, the Dong son culture was appeared later in Southeast Asia. The Dong son was also one of the flourishing cultures during Bronze and Iron Age period in Southeast Asia. In geography, the center of the Dong son culture was located in the Red river valley at the North Vietnam. It was named by the village where the archeologists had found. The Dong son culture was not form independently and it was probably developed from the local Neolithic cultures at Vietnam such as the Dong dau. Different to the Ban Chiang, there was the monarch kingdom (Văn Lang and Au Lac) appeared in Vietnam. The Dong son people did trade in Southeast Asia and also China and India by sea, it made the Dong son culture was influenced and transformed by the Indian and the Chinese. In 43 AD., the Dong son was occupied and rude by the Han dynasty in China. The characteristic of the Dong son culture was the bronze object with the high level craftsmanship. Till the Dong son period, the people mastered the technology and skill of the bronze making, they used the metals to make many different kind of metal tools. The metallurgy and the bronze making was in a very high level, and they developed their own sophisticated metallurgy techniques based on the special quality of the bamboo and they were able to use the bamboo to fashion a fire-piston that produced the heat required to liquefy metal.  [1]   The Dong son people used the metal tools in their life, especially the bronze. They used the bronze in making the agricultural tools such as the ploughshare, axe, spade, sickles and hoe etc, (few of them were made by iron) it reflected that the agriculture was high developed in Dong son and the ploughshare was the typical agricultural bronze tools in this culture, it showed and proved that the Dong son people had already domesticated and used the water buffalos strength in their agricultural activities. Besides the agricultural tools, many weapons were found in the relics of the Dong son culture. It might reflect that there were wars happened in this region. There were various of weapons were found and it included the arrows, axe, daggers, spears, swords and breastplates etc., different kind of these weapons showed that the military technology of the Dong son people was quite completed. On the other hands, the weapons were rich of decorative patterns, those patterns were vividly and detailed. The weapons were made in many different shape and the patterns was usually animals and human figures, it represented that the metallurgic technology of the Dong son people was very sophisticated and we can also see what the Dong son people looked like from the patterns. Not only metals, the Dong son people also used the potteries as the utensil for their daily life. The jars, pots, basins, vases and jugs with the decorative patterns were found in the Dong son relic. Some of these utensils found in the relic of burial were filled with the jewelry and even the skull, ash, human bones and remains of the dead people. This relic told us that the pottery jar was not just used for utensil, it was also used as the coffin in the funeral. In the relic, the archeologists found abundant of the jewelry. This jewelry was mainly made of bronze and there were other materials such as the gemstones, glass, iron and shells etc. Some of the ankles rings were decorated with the small bell and it would made sound when people move. It represented that not only for the dead people, the people alive were like to have the jewelry for making themselves more attractive. Except for the pottery and jewelry, there were musical instruments found in the relic. It reflected that the spiritual life of the people and the most representative musical instruments was the Dong son bronze drum. The usage of these drums was still uncertain (it might be used for religious, celebrations or regalia) but many evidences prove that the drums were traded as the goods in China and the Southeast Asia. The ship pattern on the drum might showing the trading activity and the star on the center of the tympanum might represent the mandala polity. Many of the patterns on the drums were seems showing the spiritual life of the people and the style of the drums were different in different regions. Some of the drums were huge and it made by the lost wax method, it made the pattern could be in more detail and showing the sophisticated of the metallurgic of the Dong son people. In conclusion, there was difference of the metal work and used between the Dong Son and the Ban Chiang culture. The Ban Chiang appeared earlier than the Dong son and its metal work was simple and mostly for the practical use. The Ban Chiang also used the bimetallic (bronze and iron) in the tools and iron in burial. Different to the Ban Chiang, the metallurgy of Dong son was more sophisticated and they used the lost wax method in the metal works. The skillful technology made the Dong son bronze working became diversification and many of the Dong son relics was in more detail than the Ban Chiang. The Dong son drums showing the trading activity and there was regalia of the Dong son people, it is very different to the Ban Chiang. The different style of the drums reflected that there were contacts between the regions and the metal working (lost wax method) skill was spread in Southeast Asia. The jewelry and different kind of the funeral of the Dong son showing that the Dong son society wa s more complicated than the Ban Chiang and there might have the social stratification in the Dong son society.

Sleep Deprivation And Academic Performance Physical Education Essay

Sleep Deprivation And Academic Performance Physical Education Essay The purpose of this study was to investigate the relationship between sleep deprivation and academic performance. Specifically, this study examined the awareness of students on the importance of sleep, to determine the average amount of sleep a student get a night, to show the correlation between sleep deprivation and academic performance as well as to investigate the comparison on sleep deprivation between Arts and Sciences students. This study employed a quantitative research methodology involving the use of questionnaires. The result shows that majority who obtain higher CGPA were those who slept for less than 7 hours, but the students who obtained lower CGPA were also those who slept less. Hence, sleep deprivation is negatively correlated with academic performance among CFS IIUM in this study. Sleep is a crucial necessity in our life as it helps to restore energy, repair the body, lose weight and keeps us mentally and physically alert (Malana, 2011). It is also very important in improving memory and reducing stress. Judy Monroe Peterson (2010) defines sleep as a state which we become oblivious to the world around us. The need for sleep is just like how we need food and water. For most people, it is normal to spend one-third of their lives sleeping. In the Islamic perspective, sleep is the sign of the power and greatness of Allah SWT in creating a perfect system in humans life. Besides, Islam clearly emphasizes on the importance of sleep. There have been many times the Quran mentions about sleep and guidance on the good nature of sleep. In the Quran, Allah says, And it is He who has made the night for you as clothing and sleep [a means for] rest and has made the day a resurrection. (25:47) Sleep deprivation is defined as an overall deficiency in the necessary amount of sleeping hours that a person is supposed to have in a day. Average adults need seven to nine hours of sleep (Morganthaler, 2011). Sleeping for less than 6 hours a night has been shown to affect coordination, mental alertness and can even lead to irritability, mood disorders, weight gain, and hallucination (Ramiccio, 2011). Previous research have shown that people who are sleep deprived perform worse on thinking and memory task than who are not suffering from sleep deprivation. If we do not get enough sleep, the memory of what we have learnt that day will possibly not remain for long. Nowadays, people tend to neglect the importance of sleep in life. Sleep deprivation is said to have been affecting millions of people around the world, especially college students. College students are more likely to suffer from sleep deprivation due to their hectic lifestyle. They often have to stay up past midnight to complete their assignments, projects and work on time. Some students even pull all-nighters as a means of learning to achieve higher grades. Research shows that students who often pull all-nighters and sleep deprived have slightly poorer academic performance than students who do not (Perkins, 2011). According to Lowry, Dean, and Manders (2010), a students GPA does have a relationship with the amount of sleep a student receives per night. In their findings, the students who slept more a night tend to get higher grades than the students who did not. The results pertaining to sleep deprivation showed that sleep quantity, and not sleep quality correlates with academic performance. Previous studies outlined by W. Kelly, K. Kelly and Clanton (2001) concluded that short sleepers would report lower GPAs than long sleepers. The lack amount of sleep the short sleepers experienced affect their academic achievement as a result of a decreased ability to focus on education-related activity. Trockel, Barnes and Egget (2000) supported that sleep habit accounts for some of the variance in first year college students GPA. Ahmed et al. (2012) also suggested that poorer academic performance is shown to be associated with a late bedtime on weekdays and weekends. Their study showed that from 410 students surveyed, 28% had excellent performance and 72% had average performance. The excellent group had an earlier bedtime every day in contrast to the average group which had a higher percentage of students who felt sleepy during class. With these propositions, it can be concluded that certain sleep habits are significantly related with academic performance. Hamza et al. (2012) in their research concerning sleep disorder also discovered that among medical students the ESS score indicated that 36.6% of participants were considered having abnormal sleep habits. Normal ESS scores (p=0.019) and the academic grades >3.75 was related with sleeping between 6-10 hours per day. The results demonstrated that abnormal ESS scores were associated with lower academic performance (p=0.002). However, contrary to other studies, a research by Mehrunissa and Anam (2011) argued that sleep did not seem to have any effect on the academic achievement. Their study showed that students who slept for less than 7 hours obtained good grades (A, B) but the majority who failed were also those who slept less. Furthermore, 63.5% of the participants still thought that sleep did not affect their academic performance. Hence, it is concluded in their studies that sleep deprivation did not correlate with students academic performance. Hence, this present research is conducted to study the relationship between sleep deprivation and academic performance among CFS IIUM students. It is presumed that students who are sleep deprived have lower GPAs than students who sleep well. The research questions to be investigated in this study are as follows: Do students consider sleep as important? What is the average amount of sleep the students get a night? How does sleep deprivation correlate with the GPA of the students? Who are more sleep deprived, arts or sciences students? Methodology Introduction This section discusses the methodology of the research. The main purpose of this research is to study the relationship between sleep deprivation and academic performance among Centre for Foundation Studies IIUM students. Surveys were administered to college students of Centre for Foundation Studies IIUM with 6000 students population to assess their sleep patterns and behaviour which correlates with their academic achievement. Data for the research were collected through distribution of questionnaires and surveys online. Instruments The use of quantitative research methodology is employed in this study which is the questionnaire. The questionnaire consists of 6 questions divided into 2 sections which comprises of demographic information and questions concerning sleep assessment. All are close-ended questions. Question 1, 2 and 3 consist of multiple choice questions while Question 4 consists of Yes/No question. Question 5 and 6 are Likert scale type of question and students are required to answer all questions. Respondents The respondents of the study were the students from Arts and Sciences programmes at CFS IIUM. A total of 50 questionnaires were distributed manually and via online surveys. Of these numbers, 16 are Arts students while 34 are Sciences students. Procedure The questionnaires were distributed randomly to all CFS IIUM students at various places such as classrooms and hostels. The surveys were also conducted online. Data Analysis For data analysis, data were entered into the computer and tabulated. The tabulated data were then presented in the form of bar graph, column graph and pie chart by using the spreadsheet software which is Microsoft Office Excel. Data were analyzed from the graph to describe the data as it was easier and more readable. Findings and Discussion This section discusses the results of the research on the relationship between sleep deprivation and academic performance among CFS IIUM students. The findings will be divided into important topics found from a survey received from 50 students of CFS IIUM. The Awareness on The Importance of Sleep Figure 1: The Importance of Sleep Among Students Figure 1 shows how each student rated the importance of sleep. Referring to the graph, it is found that majority of CFS IIUM students were aware that sleep is very important which comprises 58% of them and almost 40% of students said that sleep is important while only 4% believe that sleep is not important. Majority of the students of CFS IIUM were aware with the importance of sleep regardless of what courses they are in. The results were anticipated as the respondents were all students and they probably had known many facts about sleep from various reading material such as magazines and books. Besides, there were handful of students with computers and internet that made it easier for them to search about this issue. To sum it up, the students awareness on the importance of sleep generally yields a satisfactory result. Number of Hours of Sleep Figure 2: Hours of Sleep per Night Figure 2 shows the average hours of sleep students get per night. Based on the figure, the results clearly show that most of the students sleep for 4 to 6 hours per night. Least students are to have been sleeping for only 1 to 3 hours and 10 to 12 hours per night. In addition, less of the students sleep for 7 to 9 hours per night. Contrary to the previous finding, even though most of the students were aware of the importance of sleep, many of them slept for only 4 to 6 hours per night. This was maybe due to more time spent on studying and students were more likely to stay up past midnight working on tutorials and assignments. Briefly said, most of the students are sleep deprived as average adults need seven to nine hours of sleep to be considered as having a good sleep habit (Morganthaler, 2011). Sleep Behaviour Figure 3: Having a hard time falling asleep at night Figure 3 demonstrates the percentage of students who have a hard time falling asleep at night on a scale of one to six, six being very true and one being not at all true. Majority said that having a hard time falling sleep at night is not true (30%) while only 8% said that it is very true. A possible explanation for this might be that most of the students were not suffering from sleep disorders. This was because having a hard time falling asleep at night indicates disturbance in sleep quality but not sleep quantity. Thus, it was probably the students, although sleep deprived, were still having good quality of sleep. Figure 4: Getting sleepy in class Figure 4 shows the percentage of students who get sleepy in class on a scale of one to six, six being very true and one being not at all true. From the figure, we can see that thirty-four percent of students said that they are neutral in getting sleepy in class and only eight percent said it is true. As what had been discussed previously, getting sleepy in class was also one of the effect of poor sleep quality. Majority said that they are neutral which means the chance to get sleepy is equal. This result shows that the act of getting sleepy is negatively correlated with less quantity of sleep. It might be due to that even most of the students slept for only 4 to 6 hours and considered as sleep deprived, their chance of dozing in class is lower indicating better sleep quality. Figure 5: Pulling all-nighters studying In general, Figure 5 reveals the percentage of students who pull all-nighters on a scale of one to six, six being very true and one being not at all true. Majority of the students chose to be neutral and none of them stated that it was very true to pull all-nighters studying. Pulling all-nighters brought the meaning of when you stay up  all  night through to the next morning with no sleep, for example, studying or working to meet a deadline. The students might be pulling all-nighters infrequently. The possible factors that might lead them to pull all-nighters were studying for upcoming quizzes and examinations and also working on assignments. Figure 6: Having a consistent sleep schedule Figure 6 demonstrates the percentage of students have a consistent sleep schedule on a scale of one to six, six being very true and one being not at all true. Majority of the students stated that it is not true to have a consistent sleep schedule. These findings suggest that the students were not having a consistent sleep schedule due to their busy daily routine. They spent most of their time studying, therefore they tend to have irregular sleep and wake times. The Correlation Between Sleep Deprivation on Academic Performance Figure 7: The Relationship Between Sleep Deprivation and Academic Performance Figure 7 shows the relationship between sleep deprivation and academic performance. Most of the students who obtain CGPA 3.0 to 3.9 and 4.0 slept for 4 to 6 hours per night. The number of hours of sleep for students who achieve CGPA 2.0 to 2.9 are also 4 to 6 hours. This part will present the correlation between sleep deprivation and academic performance among CFS IIUM students by assessing their CGPA. It is hypothesized at the beginning of this study that students who are sleep deprived has lower CGPA than students who sleep well. What is very significant here is, even though, the students were sleep deprived, they still managed to obtain good results and higher CGPA. But, the students who achieve lower CGPA were also those who suffer from sleep deprivation. In other words, sleep deprivation may and may not affect students academic performance. It is probably other factors that may give impact on students academic achievement other than sleep deprivation such as learning style and level of intelligence. This result of this study seemed to confirm the findings of a study by Mehrunissa and Anam (2011) which also suggested that sleep did not seem to have any effect on the academic achievement. This finding however contradicts another past research finding. Previous research suggested that sleep deprivation has a positive relationship with poorer academic performance. The results pertaining to sleep deprivation showed that sleep quantity, and not sleep quality correlates with academic performance (Lowry, Dean Manders, 2010). Sleep Deprivation Between Arts and Sciences Students Score Number of Students 1 6 10 7 8 7 9 15 30 16 > 3 Table 1: Score of Epworth Sleepiness Scale Table 1 shows that majority of the students obtain the score of 9 to 15 which comprises 30 of them. Scoring 9 to 15 indicates that the subjects are sleepy and should seek medical help. Only 3 obtain 16 or more which showed that they were dangerously sleepy. 10 students score 1 to 6 which means they get enough sleep and not sleep deprived. Furthermore, 7 students obtain 7 to 8 which is the average score indicating also adequate sleep. From Table 1, the students were classified according to their programmes, Arts or Sciences. Figure 11: Comparison of Sleep Deprivation Between Arts and Sciences Students Figure 11 demonstrates the comparison of sleep deprivation between Arts and Sciences students. Based on the Epworth Sleepiness Scale scoring on a scale of zero to three, three being high chance of dozing and zero being no chance of dozing, it is found that Arts students were more sleep deprived than Sciences students. 75% of Arts students suffered from sleep deprivation and only 62% of Sciences students were sleep deprived. This result may be explained by the analysis of Epworth Sleepiness Scale previously which is used to measure level of daytime sleepiness. The questionnaire asked the subject to rate his or her probability of falling asleep on a scale of increasing probability from 0 to 3 for eight different situations that most people engage in during their daily lives, though not necessarily every day. A score of 10 or more is considered sleepy. A score of 16 or more is very sleepy. If you score 10 or more on this test, you should consider whether you are obtaining adequate sleep, need to improve your sleep hygiene or need to see a sleep specialist. Conclusion This research investigated the relationship between sleep deprivation and academic performance. Primary data were collected by randomly distributing questionnaires to 50 students. The following conclusions can be drawn from the study. To begin with, this study has shown that majority of the students knew the importance of sleep in their life. Nevertheless, most of the students in CFS IIUM in this study sleep for only 4 to 6 hours and may be considered as sleep deprived. The occurring of sleep deprivation might be due to their hectic lifestyle. In addition, the students in this study seemed to have quite a good sleep habit and behaviour. The results pertaining sleep behaviour showed that most of the students have a good sleep quality even they were lacking sleep quantity. The main gist of this study is the correlation between sleep deprivation and academic performance. This study showed that majority who obtain higher CGPA were those who slept for less than 7 hours, but the students who obtained lower CGPA were also those who slept less. Thus, the results of this study support the idea that sleep deprivation are not significantly related to academic performance among CFS IIUM students in this study. Undeniably, there are limitations in this study. One of the limitations is that this research was conducted only to 50 respondents of CFS IIUM students. The sample size may also have been insufficient to assess the topic under study. Moreover, the questionnaires were also distributed randomly causing uneven number of Arts and Sciences students. The results may differ when compared to other institutions.

Carl Sagan And Swifts A Modest Proposal :: essays research papers

"Carl Sagan would be pleased. It is his The Demon-Haunted World that opens with a story concerning a taxi driver: The driver, once realizing it is Carl Sagan, â€Å"that scientist guy,† in his cab’s backseat, proceeds to bombard Sagan with questions about truly scientific issues in the vein of â€Å"channeling,† â€Å"Nostradamus, astrology, the shroud of Turin.† And the driver presents each of these subjects â€Å"with a buoyant enthusiasm.† Yet Sagan disappoints him. With a list of facts, Sagan tells the man why there is a 99% chance each of his pseudoscientific theses are not true or why sometimes there is just a much simpler explanation which Occam’s Razor dictates we take. This respectful and modest logical deconstruction of absurd ideas is a compelling aspect of Sagan’s writing style. Enter Jonathan Swift: Jonathan Swift’s essay â€Å"A Modest Proposal† parallels Sagan’s style in its logical, mathematic al, and unpretentious tone. However instead of Sagan’s deconstructing of absurd ideas, Swift constructs one. A second difference is purpose: Sagan’s is science; Swift’s, satire. Swift lets us know right off the bat that the fictitious author of his essay is a cultured man. One finds the first evidence of Swift’s authors formal background in the title, â€Å"A Modest Proposal: For Preventing The Children of Poor People in Ireland From Being A burden to Their Parents or Country, and For Making Them Beneficial to The Public.† Swift then continues to drive the point home by using complex sentences throughout the rest of the essay, as well as maintaining a relatively high level of diction (there’s not a contraction to be found in his essay). Swift uses â€Å"sustenance† in instead of â€Å"food† and â€Å"prodigious† instead of â€Å"large† to help accomplish the writers status as sophisticated. With some knowledge of the time period this essay was written in, one realizes that Swift’s fictitious author satires the way the English treated the poor during Ireland’s potato famine. It is the complex sent ences and formal diction which are supposed to indicate that the author is one of Ireland’s English Occupiers. Only a few lines in the essay begins to stress its logical approach by describing babies and their mothers in the most scientific of ways; â€Å"It is true, a child just dropped from its dam may be supported by her milk for a solar year.† First, one may note the connotation Swift’s phrase â€Å"dropped from its dam† gives. This phrase does refer to birth but is normally reserved for farm animals, which is how Swift shows the author’s feelings towards the Irish poor (or lack there of).

Food production Essay

There are staggering numbers of people all over the world who experience hunger. Many people believe that hunger is caused by the insufficient supply of food. More importantly, it is assumed that due to the large population of the world, an inadequate amount of food is produced. However, this is a completely false assumption for as Robbins said, â€Å"There is enough food in the world to feed 120 percent of the world’s population on a vegetarian diet. † (Robbins, p. 178) This fact then brings about the question, if there is enough food, then why do so many people go hungry? The answer lies in the economics of food production. Food is now a capitalist commodity. Therefore, the production of food must be seen as the production of any other market commodity. Food production is not driven by global need, it is driven by market demand. As Robbins mentioned, â€Å"Food production is not determined necessarily by the global need for food; it is determined by the market for food. † (Robbins, p. 186) Looking at food production from this perspective will reveal the factors that affect the production of food. The market for food refers to the number of people that have the means to buy and pay for food. However, since a large segment of the population lives in poverty, there are very few people who can afford food. Since it is demand that determines the amount of food to be produced, the lower demand translates to lesser food production. Producers do not want to produce at a maximum level because it will mean an over-production. This will result to lower prices and ultimately lower productivity. Another factor that affects food production is the fact that farmers tend to use land to produce non food crops such as tobacco and corn as well as for crops that are marginally nutritious. (Robbins, p 186) The choice of what crops to plant relies on what the market demands. For instance, farmers tend to prioritize planting coffee for there is a large global demand for this. Coffee produced in agricultural countries in Africa is not necessarily for local consumption; it is produced because the more affluent nations demand it. Farmers consider the profitability of producing certain crops and coffee production is considered to be more profitable than vegetable production. Another example is soy bean. Soy bean is not as nutritious as vegetables. However, since there is a market for this crop in the more developed countries, farmers tend to plant this rather than vegetables. A more concrete and evident example of how market demand drives food production is the production of beef. Robbins discussed why Mexican farmers tend to concentrate on beef production. â€Å"People in Mexico go hungry because land is devoted to the production of beef, which few Mexicans can afford, but which brings high prices in the United States. † (Robbins, p. 186) The rationale behind this is that food production is driven by the demands of the markets that have the money to buy food. There is no question that there is enough food to feed the world. Hunger cannot be attributed to the inadequate amount of food. Hunger is a result of an economic problem. Lack of food on the plate is a result of the lack of money to buy food. Food production is no longer determined by the need for it by everyone. It is driven by what people who have the means to buy food demand and want. Food has become a commodity rather than a necessity. The solution of the problem of hunger lies not in production but in distribution. As Robbins (p. 187) said, â€Å"Rather than seeing hunger or famine as a failure of production, we can focus on a failure of distribution†¦ The goal is simply to establish, reestablish, or protect entitlements, the legitimate claim to food. † Reference: Robbins, R.

FAN UP Market Analysis and Sales Projections Essay

FAN UP is positioned within the Smartphone Applications Industry. Mobile devices with remote internet capability, smart phones, have created an entirely new market of users that can be reached on the go. Due to the recent nature of Smartphone technology, we are witnessing rapid growth and innovation in the smart phone applications industry. FAN UP allows the event host the ability to seamlessly pair a sponsor with individuals coming to the event. By doing so, FAN UP will open the door to endless brand reach through Social Media via the user, additional in- ­Ã¢â‚¬ game/concert advertisement, fan appreciation, and a creative way for each event host to use their event to leverage underutilized sponsorships and promote their brand. Industry Analysis Mobile applications have changed a number of industry landscapes in recent history. This industry shows annual growth projections from 2009- ­Ã¢â‚¬ 2014 to be 49.8% and from 2013- ­Ã¢â‚¬ 2018 to be 28.9%. The evidence of this growth is a reason this app will be successful. Competition in the Smartphone Applications Industry is very strong. Because of this, it is important to analyze the different forces at work within the industry. This chart, information gathered from IBIS World, lays out the industry structure: Life Cycle Stage Growth Revenue Volatility Very high Capital Intensity Low Industry Assistance Low Concentration Level Low Regulation Level Medium Technology Change High Barriers to Entry Low Industry Globalization Low Competition Level High The first key external factor in this industry is the number of mobile internet connections. As the number of smart phone purchases increases with the number of mobile internet connections in 2014, app developers will have a larger market for their products. Secondly, as demand from e- ­Ã¢â‚¬ commerce increases in 2014, retailers have expanded their product lines, the platforms on which they operate, and retailers are expected to create more shopping apps to assist time- ­Ã¢â‚¬ strapped consumers. Next, time spent on leisure and sports represents one of the most key external factors. Time spent on leisure and sports is expected to decrease slowly in 2014, resulting in a potential threat for the industry. While the industry now serves a broad audience, leisure time is a major restrictive factor in a consumers’ ability to use and purchase smart phone app products. The US Census Bureau data re- ­Ã¢â‚¬ iterates more of the same industry trends. â€Å"In 2011, U.S. nonfarm businesses with employees spent a total of $289.9 billion on non- ­Ã¢â‚¬ capitalized and capitalized information and communication technology (ICT) equipment, including computer software. This represents an increase of 10.6% from 2010. Of the $65.2 billi on spent on noncapitalized computer software, $29.9 billion was for purchases and payroll for developing software, an increase of 7.3% from 2010. $35.3 billion was for software licensing and service/maintenance agreements, an increase of $3.9 billion (12.6 percent) from 2010.† Although the growth of mobile apps is on the rise, revenue earned from these apps is expected to increase at a slower rate. Over the next five years, consumers are expected to continue wander away from pay- ­Ã¢â‚¬ to- ­Ã¢â‚¬ download apps, forcing developers to embrace the â€Å"freemium† business model that relies on monetizing free downloads after the fact via in- ­Ã¢â‚¬ app purchases. By 2019, free downloads are expected to account for about 95.5% of total mobile app store downloads. In the five years to 2019, revenue is expected to experience a 28.9% increase, reaching a total of a $34.7 billion smart phone application industry. Market Analysis The market analysis for FAN UP is atypical of most apps. FAN UP will start by focusing on the target market of Sports Franchises in the US and Concert and Event Promotion in the US. FAN UP will serve Gym, Health and Fitness Clubs in the US, Ski and Snowboard Resorts in the US, and Amusement Parks in the US in the secondary market. The sports franchise market in the US is comprised of sports teams or clubs that participate in live professional or semiprofessional sporting events (e.g. baseball, basketball, football, hockey, soccer and other team sports) before a paying audience. This market makes up the first half of the target market. Over the five years to 2013, revenue is expected to grow at an average annual rate of 1.4% to $23.6 billion, and includes a 1.5% increase in 2013 alone. The key external factors for the sports franchise market loosely hold true for the entire scope of the FAN UP market. The external factors include per capita disposable income is expected to increase by 0.8% during 2013, the number of households earning more than $100,000 is expected to increase slowly over 2013, external competition from other sports franchises is expected to increase during 2013 which represents a threat in the industry but not the market, and time spent on leisure and sports is expected to decrease slowly during 2013. Industry revenue is expected to expand 1.5% in 2013. Also, some franchises are opening new or remodeling existing stadiums to attract more consumers. Concert and Event Promotion in the US is the second half of the target market. This market creates, manages and promotes live performances and events, ranging from concerts and theater performances to state fairs and air shows. This industry has an annual growth projection of 2.6% from 2013- ­Ã¢â‚¬ 2018 with 49,825 operating businesses. Federal funding for Creative Arts is the key external factor that deviates from the sports franchises market. Many nonprofit establishments in this industry rely to some extent on federal funding, particularly grants from the National Endowment for the Arts, an independent agency that Congress established in 1965 to support the arts. Federal funding for creative arts is expected to increase slowly during 2013. This market has a history of good performance even when other industries struggle. Except for moderate wavering in 2010, the economic downturn ha s done little to deter Americans from attending live concerts and other entertainment events. Over the five years to 2013, industry revenue has grown at an estimated annualized rate of 1.3% to $23.7 billion, including a 3.5% anticipated increase in 2013. Revenue Model FAN UP will create revenue through brokerage fees, reach bonuses, and advertising. This recurring revenues model will be paid by the host of the event (i.e. Carolina Panthers, Live Nation, etc.) for each event in which FAN UP participates. The app will be free from the App Store because, as shown in the data, consumers are increasingly less likely to pay for an app. The brokerage fees are for the access to the app’s consumer base. The reach bonus is in place because with more reach, the more the host can charge the sponsor of the FAN UP sponsorship package. The FAN UP pricing will be dynamic in that negotiations must take place with each new partner in order to agree upon the percentage of the FAN UP sponsorship that FAN UP will receive. The price of the FAN UP sponsorship package will be a negotiation be tween the event host and the brand. Works Cited: 1. IBIS World 2.

Sitting System For People Health And Social Care Essay

Appropriate posing positions are varied, it depends on activity taken ; working at a desk, computing machine, driving or eating. However, these actions have a same rule to concern: stable and comfy. Human sitting is asymmetrical and dynamic, when Sitters feel non comfy with their seats they will brace themselves. And ever has changeless motion at least every 5-10 proceedingss to diminish the force per unit area on the contact points, avoid terrible pressing on any portion of the organic structure until cause hurt.1.3.1 Biomechanics of sitingBiomechanics utilises the Torahs of Physicss and the constructs of Engineering to depict the gesture formulated by assorted organic structure sections and the forces moving on these them ( Chaffin and Andresson, 1984 ) . Appropriate posing positions are varied, it depends on activity which taken ; working at a desk, computing machine, driving or eating. However, suited sitting place in biomechanics is the balance of forces and minutes. balance plane1.bmp F = Force M = Moment Balance of forces and minutes in all planes Biomechanics has emphasised the relation between the organic structure ‘s Centre of force per unit area ( COP ) and its Centre of mass ( COM ) . The COM is a point equivalent of the entire organic structure mass and is the leaden norm of the COM of each organic structure section in all planes while the COP corresponds to the point of application of the force under the country of contact with the place surface ( Lacoste et al. , 2006 ) . In order to equilibrate the organic structure over a stable sitting base, the COM is straight over the sitting base. Stability of sitting position is able to better when the country of contact between the organic structure and the support surface are increased. The relationship of the stableness with country of contact and forces is following: Stability Therefore increasing the size of the base of support will increase the stableness ( Ham et al. , 1998 ) . For some postural malformations, the country of the support base is reduced therefore the stableness is improved by addition the support country such as supplying the chest support bole support or buffering on the seating. The balance of sitting encourages the right form or position of spinal. In sidelong position, alliance of spinal is looked somewhat S- form. The key of stable base is the pelvic girdle. In the basic of normal posing, the pelvic girdle is centred and rotates rearward as a consequence of the tenseness in hamstrings ( posterior thigh musculuss ) . For maximal stableness and minimal musculus attempt when keeping an unsloped position ( every bit same as in the erect standing place ) , the Centre of mass of the upper organic structure should be maintained over the ischeal tubercles ( Zacharkow, 1984 ) balance plane2.bmp The contact points of the seated position are ischial tubercles, thighs and pess. By supplying support through the thighs, legs and pess, force per unit area is reduced over the ischial tubercles. The thighs are parallel to each other and in the natural place. For the ground that thigh musculuss span the hip and articulatio genus, the grade of hip flexure and knee extension on the seating should be avoided to pull of hamstrings. A upper limit of 100 grades of hip flexure and 105 grades of articulatio genus extension is advised ( Mayall and Desharnais, 1995 ) . The pelvic girdle rotates somewhat forward promotes flexure of the lower dorsum or lumbar hollow-back. It will be curved concave to the forepart to back up the weight of the upper portion: bole, weaponries and caput. However, for the people with physical disablements who are lacking in postural ability and postural dissymmetries can besides take to orthopaedic malformations, uncomfortableness, decreased physiologic maps, self-image, and quality of life ( Trefler et al. , 1993 ) . Consequently, users with a motor disability need a seating which can counterbalance for the stableness and besides back up the functional and postural ability that each person has. There are many ways to depict the assortment of siting systems for people with physical disablements. However, in this survey, the seating system will be categorised by 3 characteristics of the chair as shown in table Twenty.Siting system for people with physical disablementsFeatureCategorizationFunctional of utilizing Wheelchair Particular seating Beginning of energy Manual Power Feature of traveling Rigid Dynamic1.3.2 Wheelchair populationA wheelchair is one of the most common devices used to help users who have limited abilities to walk or travel. The wheelchair user population includes kids, grownups, and aged individuals. There are many grounds for their disablements: birth defects ( kids who have motion upsets ) , accidents ( an hurt to legs or the spinal column, which controls leg motion ) , infirmity diseases and old age. Harmonizing to Wheelchair foundation, â€Å" over 100 million people with physical disablements worldwide need wheelchairs. It is estimated that the figure of people who need wheelchairs will increase by 22 per centum over the following 10 old ages, with the greatest demand bing in developing states † ( Behring. , 2009 ) . In UK, there are an estimated 10 million handicapped people, about 20 % of population ( Office for National Statistics, 2010 ; Statisticss, 2008 ) and 5 % of people with disablement are a motor damage ( NHS, 2004 ; Wray, 2005 ) . The proportion of wheelchair population additions with age. Separate into three age groups: kids under 18 old ages of age, grownup 18-64 twelvemonth and aged 65 and older, the highest rates are found among the aged population so working age and non many in kids. There are assorted wellness conditions and damages doing a individual demand to utilize wheelchair and these grounds are diverse in different age group of users. In table Twenty shows the wellness conditions and damages reported as the chief cause of functional or activity restriction. Stroke 11.1 % Arthritis 10.4 % Multiple induration 5.0 % Absence lower appendage 3.7 % Paraplegia 3.6 % Orthopaedic lower appendage 3.6 % Heart disease 3.3 % Cerebral paralysis 3.1 % Rheumatoid arthritis 3.0 % Diabetess 2.4 % ( LaPlante et al. , 2009 ) Manual seating system is the chair that needs self impeling by users or health professionals. The users of manual wheelchairs by and large have lower appendage failing, palsy, or amputation doing walking insecure or hard at best. They may include persons with spinal cord hurts, unilateral paralysis and other types of palsy, multiple induration, intellectual paralysis, spina bifida, arthritis, and lower limb amputations. Typically, the user is a paraplegic or quadriparetic individual who desires to manually impel himself every bit much as possible for the exercising and ensuing wellness benefits. For the wheelchair dependent individual who has to impel by his or her ain, the most common country of musculoskeletal is the shoulder. This is because users normally have overload on their upper organic structures to turn the wheels of the wheelchairs. In 2008, Desroches et Al. published a paper in which they studied the relationship between the effectivity of the attendant force at the handrims and the mechanical burden by the net shoulder minutes. They found that more force demands are more at hazard of shoulder hurts on the land that overexploitation. Furthermore, elbows, carpuss and custodies are besides injured because they are non designed to get by with the insistent contact with the wheelchair pushrims. This frequent insistent burden may be one of the possible causes of the incidence of carpal tunnel syndrome. Powered wheelchair theoretical accounts are controlled by the user ‘s manus with a little control stick. Users who unable to utilize a manus for maneuvering and control may be capable of a oral cavity control or breath control device. These power wheelchairs are much safer to run with a computing machine inadvertence. However, serious accidents sometimes result from feeling or computing machine system failures. ( N.I.R.E. , 2004 ) . The failures may be elusive 1s non recognised by users. Otherwise, they can be in the signifier of a sudden, unexpected entire failure of the wheelchair computing machine system, which may ensue in an accident when happening at a critical clip.1.3.3 Particular SeatingParticular seating designed for people with physical disablements considers demands like phase of development, disablements and other upsets. At the same clip, ought to see as position, force per unit area and comfort. The mobility and position jobs that motor impairment people face may be due to muscle failings, musculus instabilities and cramp or hapless esthesis. There are many grounds for their disablements like birth defects ( kids who have motion upsets ) , accidents ( an hurt to legs or the spinal column, which controls leg motion ) , infirmity diseases and old age. Siting is a work of complex coordinating of human constructions. The form of the pelvic girdle is unstable by nature in sitting place. It can non be kept stable without the cooperation of organic structure musculus and limbs. In add-on, a proper design of constituents such as place backrest, armrest, footrest, etc. , is encourage stableness in the sitting place and the comfort of the place. First and the foremost for handicapped posing is the importance of stable posing, it is achieved if there is a balance of forces and minutes in all planes ( Letts, 1991 ) . An unstable sitting non merely makes upper organic structure hard to command balance but besides non keep the good place of physiology. A particular place base with a back support can be used which would assists the patient who is being positioned for physical therapy. The supports are made from stuffs such as plyboard, froth and polymer. These stuffs provide postural support and alleviate the force per unit area for patients who have unbalanced organic structures. Nevertheless for kids who have the spasticity CP, they will do their organic structure imbalanced and unstable when have extensor cramp. This in bend makes the patient uncomfortable and impairs their functional ability. Furthermore, CP kids need more seating demands than a broad assortment of people with disablements because of their overactive stretch physiological reactions and irregular stableness. The force per unit area sores are besides considered because this frequently occurs when sitting for a long clip without traveling. A considerable sum of literature has been published on biomechanics of siting system with spastic CP patients, they have investigated the force per unit area forces in sitting place and strong forces of extensor push in patients which impart onto their wheelchairs and they found that high forces can besides do hurts for the kid ( Dawley and Julian, 2003 ; Hahn et al. , 2009 ) . The force per unit area ulcers that suffer from force per unit area force in sitting have been concerned for many decennaries. Harrison et Al. published a paper in which they reviewed the literature of sitting biomechanics in normal organic structures. The thought of dynamic seating has been designed in Germany since 1884 for mills that had adjustable backrests and place undersides with rounded forepart borders to cut down force per unit area on the under-thigh part ( Harrison et al. , 1999 ) . The chief aim of presenting the dynamic seating to the design of the chair is to avoid the force per unit area ulcer. Dynamic siting systems have been available on the market since 1989 ( Hahn et al. , 2009 ) by including spring loaded, elastic constituents or powered devices, in the outlook that it will react suitably to the users with strong musculus cramp, cut down the hurting and cut down force per unit area from restricted position. For people with physical disablements particularly patients who have strong extensor spasticity the dynamic design ease them non merely to forestall the force per unit area ulcer and hurt to the user but besides prevent breakage of the chair. Dynamic seating constituents are designed to travel as a consequence of forceful motions exerted by a client ( Magnuson and Dilabio, 2003 ) . The dispute of the effectivity and impact of the surrogate design has been discussed. Several surveies have attempted to explicate that to repair a place would be more goo d for patients ‘ physical therapy than to change the sitting position every clip of extensor cramp ( Barnes, 1998 ; Herman and Lange, 1999 ) . However, the surrogate design is presumed that when musculuss stretch, the forces produced between place ‘s parts and their organic structures would diminish with usage of the dynamic constituents. Furthermore, this system can be approved and it does non hold any negative consequence for the long term use. The basic apprehension of physical features of the user is indispensable for the design and consideration of postural support. Furthermore, it is really indispensable to understand the scope of the forces that are being applied to the user ‘s organic structure when using postural support within a seating system. Barnes M.R.
