The Declining Values in Society Especially Among Youths free essay sample

Malaysia now and before has a huge and tremendous of differences. Look at the streets, the buildings, the facilities and other infrastructures; not all but most of it is in a good condition. Moreover, in most part of the country is covered by natural greens that provide us healthy environment and also clean air to breath. With many attractions in our country, Malaysia is now a tourist target for their vacation. All these achievements are not done by one man but it is the full cooperation of the citizens. However, in the long run, the workforce ages and here comes the new generation to pick it up from them. So, it is very vital that the youths are going to the right path of life to ensure the future of our country. But as we witness today, more and more children are having lots of social problems including fighting, crime, murdering, stealing and many of them left school at a very young age. We will write a custom essay sample on The Declining Values in Society Especially Among Youths or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Also, the statistic shows that cases of crimes are arising and at a worrying state. What is happening? Why is it uncontrollable? What are the best solutions? These are common questions arise among us. First and foremost, I would like to pint point the parents, not to criticise them but to make them realize what went wrong between them and the children. A baby after birth is as if a pure white cloth with no dots or tears and the parents paint the colours on to the cloth as the kid grows. In other words, parents interactions with their children facilitate childrens moral development. Indeed that parent is too busy with their daily working schedule because of the demanding high cost of living as they work very early in the morning and only back at late night. By practicing this lifestyle, there is certainly no time for interaction with their children and definitely parents have no single idea of what their children does while they are at work. With no one to control the children, they will have the maximum freedom to do their favourite things rather it is good or bad doings. If it is good, there would not be a problem, but what if things turn the other way round where they reach drugs, illegal racing, stealing activities and so on. So, it is very important that parents take care of their children 24 hours a day to avoid unnecessary happenings. Next point that I would like to stress on is less teachings of religion to the young ones. I believe that all the religion in this world teaches us the right things to do and none of it is negative activities. Nowadays, religion activities are not implemented by the parents themselves and not practiced as a part of daily ruitin. Then, how would you aspect the children follow the parents’ virtue footsteps? Prayers are forgotten, the Holy Bible is left untouched, holy and pure places of the respective religion are not being used. What is going to happen? Let me tell you what will possibly happen, strong belief or trust in God will be fragile and easily crumble soon enough. The youths would not be able to think rationally as in unable to differentiate good or bad and love or hate as there is no one to guide them the right way. This is mainly because of human learn and does bad things much quicker than doing good. If things turn out ugly, the children will be easily influence by a certain corrupted society in our country. As we all know, teenagers are stages of life that is unstable and likely to discover new and interesting things to do. Hence, it is best that the teens are under control to prevent further corruption. My third stand on this topic is corrupted and immoral friends influent. We spend most of our time with our dear friends more than our family members as a student. So, choosing the right friend is very vital as it may lead to disasters if chosen wrongly. When a teenager mix and mingle around the rotten mates, he or she will also be brain washed and encouraged to be polluted as the whole group is. Drugs and also cigarettes will be part of the gang’s activity. Not only taking in those poisonous deathly chemical into the body but also selling them to make more profit and to get more stocks. Other than that, as for teen girls, they will be easily fall into traps made by their perverted boyfriend. Not to say all female youths but mostly are cheated as they trust the wrong person in life. As the impact, babies are born before marriage and young mothers are left and dumped by their irresponsible so called ‘soul mate’. Then the young mother has no choice but to throw away the poor newly born baby to run away from their responsibility. Is this ethical? Of course not, this is very immoral n uncivilised doings. To prohibit this from happening, choosing the right friend is very important from the very beginning. Last but not least, is the corruption caused by influence of the western countries. Why I say so? Look at our teens today, they seem to be mimicking the popular actors and actresses from the westerns. That and also their free style culture is monopolising our very own culture. Now, every single home has at least one television and western culture is spreading through this electrical square box fast and effective. Freedom of interaction and clothing fashion trend are two of the most major influential on the youths today. There are films that focus on sex relation created by foreign directors, but that is not the end of it, there are also movies that has an abnormal sex storyline and the best example is ‘Broke Back Mountain’ directed by Ang Lee from the United States. Besides that, clothes that the teens wear now are very improper and disrespecting. Mini short skirts, sleeveless T-shirts and bareback clothing are a few example of not suitable clothing. What are they trying to prove to show so many of their skin? This style of wearing baits perverts and distracts the mind of the opposite attraction. So, preventing the teens from being influenced is truly vital and needed till they are mature enough to think by themselves. Based on the perspective I have given above, it is not made up and it is really happening in real life. Frankly to tell, through out my life I have witness and experience it before. I am now able to think wisely and critically in every step I make in life. I do not regret but I am truly glad that I fell and experienced the bitterness of life because by so, I can change and improve myself to be better in many ways. If I did not fall, I will not learn anything and keep on repeating it without knowing the result later on. There are always solutions or remedies to problematic conditions. To begin with, parental love helps a child take in vital virtues and discipline. Parents who spend quality and quantity time with their young ones as well as love and care for them will have the children to gain higher levels of moral development. A gapless family gives children examples to learn from, values and cultures to be practiced, and a support system to turn to in times of need. When children feel linked to the family, they will feel comfortable and safe. However, excessive parental control can lead children to make poor choices just to get some freedom. On the other hand, too much freedom leads to children feeling overwhelmed and bossy. With uncontrolled of freedom, children may get the idea that parents dont really care what they do or what kind of person they become. So, parents should handle their kids with modesty of parental control. Have your children complete chores and jobs around the house, take responsibility for their own homework, or take care of a younger sister or brother, an ill family member, or pets. Volunteering, service projects, and giving to a charity provide an opportunity to give of self through responsible action. Changes made to the education system can also be a solution to this matter. It is important to shape an education system such that it produces a high quality of new generations who are able to cope with the demand of the real world. In order to do this, some significant changes need to be made to churn out sturdy and strong minded individuals. Firstly, classes should be shrunk to a smaller group. A ratio of 20 students to a tutor is far more effective and constructive compared to a ratio of 50 to one. In smaller classes, individual attention can be meted-out by the tutor consequently this will bring about the increase in the quality of students who leave their study life. Tutor will be better able at disciplining and molding the students too. Besides, the quality of a tutor is crucial to a solid and functional education system. The tutors should not only be masters of the subject that they teach but also be masters in communication, language, psychology and character building. It is fundamental for the tutor to be enthusiastic, confident devoted and dedicated to the vocation of teaching. This is to ensure no one to suffer for the lack of interest on the part of the tutor. There was a general view that there are limited activities that appeal to young people and this contributes to young people loitering in town when they should be at school and at night. So what can be done instantly and effectively? Education, skills development and providing employment opportunities for young people are essential to engaging with young people. Not only the government but also non-governmental organisations (NGOs) can do something about it from it being worsen. Reinforcing the need for and benefits of education to parents, families and communities is crucial to ensure the society is heading to a healthy and proper way. Provide learning opportunities to youths that are relevant and significant to improve their daily lifestyle. Create better linkages between youth organisations and schools to support young people; hence problems can be solved quickly and easily and most important efficiently. Further develop and strengthen programs focusing on skills development, work experience and mentoring for young people is a solution too. By developing better partnerships between school and businesses, young people will be molded to prepare for work. Nevertheless, positive stories about successful youths should be demonstrated to other young people what they could achieve or aspire to. It is always good to follow positive footsteps because you will know that u are at the right route in life and never go wrong. To put it in a nutshell, everyone including parents, tutors, government or the NGOs and even the youths themselves should work hand in hand to overcome this chronic issue among the teens. This is mainly because the teenagers today are a very essential asset of the future. As the ups and downs of the country depends on the shoulder of the youths now. If the teenagers today are knowledgeable and has first world attitude, then our country will be standing stiff and strong for the time to come. So, let us all help out, even a little bit to make Malaysia a better place to live for now and forever.

ghandi a great leader essays

ghandi a great leader essays Few men have ever had as much of an effect on our world as Mohandas Gandhi, though he used the message of peace and love, rather than war and destruction. One time a prominent lawyer in South Africa, Gandhi gave up practicing law and returned to India in order to help ease the suffering of the repressed people of his homeland. Gandhi's love for people and his religious passion made him a revolutionary in many of his ideas and actions. On October 2, 1869 in Porbandar, India, a region of Queen Victoria, Mohandas Gandhi was born to Kaba Gandhi and his wife. Although his father, Kaba, was the chief Minister for the Maharaja of Porbandar, he and his family lived in a small house and belonged to a Hindu caste of merchants called "banjas" (Iyer, 34) As he grew, Mohandas became a small, shy and skinny boy, afraid of others' opinions. At the age of thirteen, he was married to Kastaurbai, a pretty yet strong willed girl of the same caste. Kaba Gandhi died when Mohandas was sixteen. At eighteen he traveled to England to study law and secretly to see for himself what made the English so powerful. In 1888, he traveled to England to become a barrister-at-law. There were several important influences that he encountered here: the Western material style of life, which he decided not to follow, and in the simple Russian way of living he found: the New Testament, and the Bhagavad-Gita, the bible of the Hare Krishna movement (Fischer, 54). It was here that he developed a sense of the presence of God in his life and the lives of men. Gandhi then returned to India and studied law in Bombay but quickly denounced it, feeling that it was immoral and could not satisfy one's conscience (Shirer, 69). His personal experiences, including being ejected from a train in Maritzburg, of not being allowed the same rights as others lead him to begin a movement to help his people. While in South Africa, Gandhi made himself poor so that he could identify wi...

The Different Meanings of Dürfen in German

The Different Meanings of Dà ¼rfen in German Dà ¼rfen  (to be allowed to) is one of the six modal verbs  that are so essential in both English and German. As with other modal verbs, it is almost always used with another verb in a sentence. Dà ¼rfen  can also take on a few different meanings, depending on its context: As opposed to kà ¶nnen  (can, to be able to), the spelling of dà ¼rfen is far different from its English equivalent may, allowed/permitted to. This makes it a little more challenging to study, but its so important that students of the German language should fully understand its various meanings and learn how to conjugate dà ¼rfen. Dà ¼rfen: To Be Allowed to The main definition of dà ¼rfen  is may or to be allowed to. This is the most common use for the verb and you will find yourself using it quite often. Darf ich draußen spielen, Mutti? (May I play outside, Mom?)Der Schà ¼ler durfte nur einEN Bleistift und einEN Radiergummi zur Prà ¼fung mitbringen. (The student was only allowed to bring a pencil and an eraser to the exam.) When it comes to dà ¼rfen,  it seems that both English and German speakers make the same mistake. Did your English teacher ever reply to you with â€Å"I don’t know if you can, but you certainly may† in response to a question you formulated with â€Å"Can I†¦Ã¢â‚¬ , instead of â€Å"May I†¦?† Germans share the same habit as you can compare in these two sentences which have completely different meanings: Kann ich bitte zur Toilette hingehen? (Can I go to the washroom?)Darf ich bitte zur Toilette hingehen?  (May I go to the washroom?) Dà ¼rfen: Polite Requests Dà ¼rfen  can also be used as a form of politeness when asking a question or making a request. Wenn ich bitten darf, mit welcher Fluglinie sind Sie geflogen?  (If I may ask, on which airline did you fly?Darf ich rein?  (May I come in?) Dà ¼rfen: A Possibility There are also times when you may want to use dà ¼rfen  to indicate a strong possibility that something will happen. To form  this meaning of dà ¼rfen, the subjunctive II must be used. Sie dà ¼rfte um 8 Uhr hier sein.  (She will most likely be here at 8 o’clock.)Meine Tante dà ¼rfte bald mehr Geld bekommen.  (My aunt will most likely receive more money.) Nicht Dà ¼rfen   When you add an infinitive verb to nicht dà ¼rfen, you express the prohibition of something. Hier darf man nicht schwimmen.  (You are not allowed to swim here.) When you add the subjunctive II and an infinitive to nicht dà ¼rfen, you express an accusation. Deine Hausaufgaben httest du nicht vergessen dà ¼rfen, jetzt bekommst du keine gute Note. (You should not have forgotten your homework, now you won’t receive a good mark.)

PAPER ON HUMANS AND ANDROIDs based on books I SING THE BODY ELECTRIC Essay

PAPER ON HUMANS AND ANDROIDs based on books I SING THE BODY ELECTRIC and movie THE ELECTRIC GRANDMOTHER - Essay Example Terror Management Theory that is built mostly from the notions of Ernest Becker begins with the idea that humans, as opposed to other creatures, face something that is possibly terrifying: the attention of our own death rate in addition to the desire to stay alive. In the words of Terror Management Theory co-creator Sheldon Solomon, the attention that you are intended to wither away to nothingness, and in turn are no more significant than a reptile or a spud, is not particularly impressive to anyone. So how do individuals deal with this awareness? From a Terror Management Theory strategy, individuals deal with death rate by doubting their own death rate, and preventing considering it. They hold back the terror, generally (for example, loss of lifestyle ideas enhance a prevention inspiration, lead individuals to embellish the potential length of their lifestyle and death ideas lower after individuals are advised of death). But, this strategy certainly is not able to a degree. We know we will die, no matter how much we try and avoid considering it. So, individuals developed social signs of significance and value that offer a sense of significance and significance, and eventually, growing old, when individuals stay up to and maintain the factors of these values (hence the human need for self-esteem), as a means of dealing with their own loss of lifestyle. This immortality can either be representational, such as by splitting information or causing worldviews and categories that continue beyond a persons loss of lifestyle, or actual, as in perception in lifestyle after death. In ‘Electric Grandmother’, a mother is replaced by an android in order for them to stay with the father and not be taken away. We find that they find an advertisement for Facsimiles’ Unlimited, a company who proclaims "I Sing the Body Electric," which is a robotic grandmother who will provide care and love to families. This is initially is just to take care

Prejudice, Stereotyping and Discrimination on the Web Essay Example for Free

Prejudice, Stereotyping and Discrimination on the Web Essay People think that racism and discrimination doesn’t exist anymore, but surprisingly they do; both existed throughout human history. Discrimination may be defined as a negative, harmful behaviour toward people based on their group membership. Whereas prejudice which is an opinion rather than a fact; is a negative attitude toward members of a group, that is often very strongly held. Stereotypes are individuals beliefs that members of a group share particular attributes; someone might think that Arabs are terrorists, or doctors are intelligent and compassionate. Unlike prejudice and discrimination-terms that refer to negative attitudes or actions- stereotypes can be either positive or negative. The Palestinian-Israeli conflict will never end, and each individual has a different opinion about it. Ahmed Ramie is a Moroccan-Swedish writer and Holocaust denier, also the founder of the radio station Radio Islam which now operates as a website. Radio Islam is a website owned by a group of freedom fighters from different countries in support of Ahmed Ramies global struggle. Radio Islam is a website that is trying to promote better relations between the West and the Arab and Muslim World; its against racism of all kids and forms also against all kinds of discrimination of people based on their color of skin and faith. Meta-Stereotypes are a persons belief about the stereotype that out-group members hold concerning his or her own group; for example Arabs would believe that Jews hold a negative stereotype of their group (terrorists). Meta-stereotype differs depending on each group; Arabs may hold negative stereotypes against Jews (Occupants). Each group may hold different opinions; Palestinians may consider that their victims of the chosen people (the Jews). Each group believes that they hold the right opinions about others and some of them would never change their opinion. Another hate site that depicts hate towards Jews is Kinsman Redeemer Ministrie, Pastor Mark Downe is strongly honest with his opinion towards Jews, and his title is why we hate Jews. Scapegoat theory is a theory proposing that prejudice occurs because members of dominant groups use discrimination against members of weak target groups to vent their frustration and disappointment. People become frustrated during difficult economic time and tend to take out their frustration on weak targets, for example Jews in Nazi Germany in the late 1930s when Hitler roused anger against Jews by claiming they had too much economic power and blaming them for the impact of the worldwide depression on Germany. Jews were an outcast that many Germans disliked, but when Hitler started his campaign of propaganda, some Germans followed his league. But theres a difference between these two sites; Radio Islam is against Zionism not Judaism, where Kinsman Redeemer Ministries talks specifically about Jews and lists different reasons why people should hate them. One man started this propaganda and changed the whole world, now Hitler is gone but people still carry on with his campaign and spread the hate and racism among others. People should be more considerate about other peoples opinions and beliefs and not hurt them by hate websites or picking on them. Each person in this world is a unique individual who shouldnt be judged based on his/her religion, color, sexuality or ethnicity. Prejudice against overweight women is common now a day, people who are overweight are the targets of widespread prejudice and discrimination, and they may find difficulties finding a job or travelling. Some groups hold hate towards other overweight people, they believe that the fat gene is not an excuse and obesity should not be common among us. If an obese saw a hate website about overweight groups they would feel ashamed and upset that they would eat more rather than fixing their problem. Old-Fashioned Prejudice is one of the forms of prejudice; the Ku Klux Klan (KKK) is name of three distinct past and present right-wing organizations in the United States. After the American Civil War the KKK was created on December 24, 1865, this group represents the White Christian civilization they believe in many concepts and rights that should be essential to civilized and moral society. Some people might find them as ignorant and racist but they are certainly convinced about their beliefs and actions towards illegal immigrants and black people. On one of the hate websites KKK they mention white all the time that others might be offended and bothered, their mission is to live in a country with white people only. Again Frustration caused this group it started after the War before that people didn’t mind black people. Martin Luther King has become a human rights icon and he represented all African Americans; he fought for their rights since the 50s. Throughout the history till the present African Americans still might feel discriminated and an outcast. Stereotypes is a huge effect on people and how they feel about others, a kid might not think of a Black man in the middle of the night as a killer or a thief but as this kid grows older and starts watching television and surfing the internet this persons thoughts will change and develop hate towards Black people and somehow fear. In all I would like to wrap up this assignment with saying that Im totally against judging a book from its cover, some people might hate all Jews because some of them occupied Palestine or some Jews would hate all Germans because some of them slaughtered them. But I think thats not only racist but its ignorant, all people should be treated the same and those hate websites can convince teenagers to turn into a hater and Im surprised how they exist from the first place. Websites I visited: -http://radioislam. org/islam/english/index_zion1. htm -http://www. kinsmanredeemer. com/WhyWeHateJews. htm -http://ihatefatpeople. wordpress. com/ -http://www. kkk. bz/.

Piezoelectricity as a Future Energy Source

Power Sector Reforms Issues And Challenges A Report On Piezoelectricity As a future energy source Submitted by: Nikhil Gupta (5th Sem) Mechanical Engg. Dept. , JEC,Jabalpur Abstract The Future Smart House is going to have a large number of sensors and microelectronic devices located throughout the house. These devices will need a clean, reliable source of energy that won’t need constant maintenance. The goal of this report is to get awareness about the piezoelectric energy sources to provide power to certain applications in the house. Initially the researchers were planning to create an energy scavenging floor that used piezoelectric transducers to harvest wasted energy in the foot strike of a human being. In consideration of the high cost and minimal power output of these piezo-sources, it seems more feasible to create small, localized energy sources rather than one large unified system. This idea has lead to several potential applications. The first is to combine a piezoelectric power source with sensors such that there would be no need to ever change the batteries in these sensors. The next application is to use piezoelectric cable throughout the floors of the house as a means of tracking. The final application is to combine piezoelectrics with a device to eliminate vibrations in household appliances. Introduction So generally Piezoelectric Energy Harvesting is based upon the piezoelectric effect. The essence of the piezoelectric effect works as follows: by applying a mechanical stress to a crystal, one can generate a voltage or potential energy difference, and thus a current. Also by applying a current to a piezoelectric one can stress or strain the material. The mechanical stress can be supplied by any source. But with so many people walking around from place to place, why not harness that kinetic energy to power stuff, right? Technical Overview Piezoelectric materials exhibit the unique property known as the piezoelectric effect. When these materials are subjected to a compressive or tensile stress, an electric field is generated across the material, creating a voltage gradient and a subsequent current flow. This effect stems from the asymmetric nature of their unit cell when a stress is applied. As seen in Figure 1, the unit cell contains a small positively charges particle in the center. When a stress is applied this particle becomes shifted in one direction which creates a charge distribution, and subsequent electric field. These materials come in several different forms. The most common is crystals, but they are also found as plastics and ceramics. [pic][pic] Fig. 1: Lead Zirconate Titanate unit cell Existing Technologies There are several companies and research institutes throughout the world who are focusing on finding useful applications for piezoelectric energy sources. Several years ago a project was done at MIT entitled, â€Å"Energy Scavenging with Shoe-Mounted Piezoelectrics. † In this project the researchers lined the bottom of a shoe with piezoelectric transducers and saw what kind of power they got out of it. They eventually attached an RF-transmitter to the shoe that was powered by the piezoelectrics. The two materials they used were polyvinylidene fluoride (PVDF) and lead zirconate titanate (PZT). Their initial results were that the PVDF material produced 1. 3 mW per foot strike and the PZT produced around 8. 4 mW. They went back and tried numerous other approaches but they were confined to working with the limitation of a shoe. In this report they hinted at the fact that much great power output could be achieved if they were not confined to working with a shoe. Another company that is looking into using piezoelectric sources to power networks of wireless sensors is MicroStrain Inc. This company setup an experiment where piezoelectric transducers were attached to the support beams in a structure. As the structure was constantly under strain, the voltage created by the piezoelectrics was stored up in a capacitor. Once the capacitor voltage reached a certain level, the power was than transferred to a transmitter which sent a wireless signal to some receiver. It was reported that the cycle time was about 20 to 80 seconds to store up a charge of 9. 5 V on the capacitor given the size of the piezoelectric was 17 cm2. A German based company called EnOcean already has a commercially available product. The slogan for this company is â€Å"no batteries and no wires. † They create products that use piezoelectric transducers to power RF transmitters. One particular product is a light switch that requires no wiring at all. Behind the actual switch is a piezoelectric transducer. When the light switch is flipped, this motion is used by the transducer to power the RF transmitter, which signals the receiver on the actual light to turn on. This would be an interesting technology to demonstrate in the house because it enables you to have light switches on places you never could before such as on a window or outside in the middle of the yard. Two other companies, Ferro Solutions Inc. and Continuum Control Corp. make small ambient energy harvesting sources. Ferro Solutions makes a product called the Energy Harvester. This little device about the size of two AA batteries contains an electromagnetic generator inside. There are two magnets and in between them is a coil of wire. When vibrations cause the coil of wire to move around in the magnetic field, current is generated in the wire. This small energy source could be used in place of batt eries or as a means to recharge batteries. The device supplies about 1 to 10 mW of power and the company is looking to license this echnology to wireless sensor companies. Continuum Control Corp. makes two different products called the PiezoFlex and the iPower Generator. The PiezoFlex is a new type of piezoelectric material that is both flexible and robust. At the same time it also cheaper to manufacture than most other piezoelectric materials. The second product, the iPower Generator contains a piezoelectric transducer that converts mechanical input into electrical output. This product was used was used as a backup energy source in an Antarctic Expedition several years ago. The device has a crank and as you turn it, the mechanical energy is converted into electrical energy. At the MIT Media Lab, researchers in the Responsive Environments Group created a piezoelectric floor called the â€Å"Magic Carpet. † This floor contained a grid of piezoelectric cables spaced 4† apart. The goal of this project was to create a floor that could track the movements of the person walking across it. This technology was then combined with lights and sound such that depending on where you walked a different sound would play. Today you can find examples of the magic carpet in some of the museums at MIT. A similar project was done at Georgia Tech. At Georgia Tech they built a â€Å"Smart Floor† that used piezoelectrics as sensing devices to monitor and predict when people were walking across it. They could predict with about 90% accuracy what person was walking across the floor just given the way the piezoelectrics reacted to their foot strike. Application to Residential There are several ways to incorporate piezoelectric technology into a residential setting. The first would be to use small piezoelectric sources in the place of batteries. These piezoelectric sources could be used to power sensors throughout the house so that the batteries would never need to be changed. Another application was proposed by MIT researchers. Their idea was to use piezoelectric materials to cancel out vibrations in certain household appliances. They envisioned a device that could autonomously adapt the amount of dampening based on the magnitude of the vibrations. They proposed that first the device be built with a battery power source and eventually switch to an energy source that converted the vibrations into energy using either piezo or electromagnetic generators. Their second idea was the opposite of the first: rather than cancel the vibrations, you would enhance them. This idea originated from the fact that subwoofers only go down to about 20 Hz, yet the electrical signal coming from the actual media contains frequencies below 20 Hz. These signals are too low for us to hear, but they can be converted into vibrations. For example when there is an explosion in a movie, there are frequencies below 20 Hz, but the subwoofer can’t make a sound with that long of a wavelength. If you were to install proof mass actuators into the floor of the media room, whenever there was a signal below 20 Hz, these actuators would respond accordingly and literally shake the room.. The next set of applications would involve piezoelectric cable. Piezoelectric cable behaves much the same way as flat piezoelectric transducers only the cable is much cheaper. The cable resembles the standard coaxial cable that plugs into the TV, but the piezo cable has a layer of piezoelectric polymer wrapped into it. This cable could be used to create a grid across the floor that could generate power from people walking across it, or the more viable purpose would be for tracking. These cables come with varying degrees of sensitivity. The cable could be used to track both the location and the orientation of a person in the house. Based on the way they walk, the floor might also be able to identify who the person is. Design The major obstacle in designing your own piezoelectric circuit is finding a way to maximize the power output. The major components involved in this circuit would be an AC/DC rectifier, a filter capacitor, and a DC-DC converter. The AC/DC rectifier converts the AC signal from the piezo-source into DC current. The filter capacitor smoothes electrical flow and the DC-DC converter is what allows the battery to store the energy. Most of the power conversion comes into play in the DC-DC converter. Fig. 2: Adaptive Energy Harvesting Circuit Recently in a paper published in Power Electronics entitled â€Å"Adaptive Piezoelectric Energy Harvesting Circuit for Wireless Remote Power Supply,† esearchers found a way to increase power output by roughly 400% compared to when a converter is not used. They used an adaptive control technique in the converter that adjusts itself to find the optimal power transfer options for every moment. Last year, MIT created a setup to demonstrate the power output you could achieve using the vibrations in a plane wing. They didn’t use piezoelectrics, but rathe r electromagnetic generators. Regardless, the circuit for capturing and storing the energy would still be the same. He still has the circuit and is willing to let us use it in designing a piezoelectric energy source. Simulation Results From the study of a project report undertaken in MIT a circuit was modeled. The circuit used a piezoelectric transducer as the voltage source which than fed into an op amp. The purpose of the circuit was to provide a voltage gain of 100. The simulation results proved that the op amp did in fact multiply the voltage from the piezo-transducer by a factor of 100. Unfortunately, in the program they could not find an actual piezo-transducer so they had to model it with an ideal voltage source with an estimated equivalent Thevenin resistance. They considered this project a success on the grounds that it proved that piezo-transducers can in fact act as voltage sources. It also showed that the voltage provided by the transducer can be multiplied by several orders of magnitude using certain circuits. This circuit essentially failed to answer the real question of what kind of maximum power one can get out of the piezo-transducer. A final word on piezoelectricity as a future energy source In the near future, the lights at your favorite coffee shop or the stereo system at your local bar could very well be powered by foot traffic. If we want to maintain a certain lifestyle in an increasingly competitive, resource strapped world, we need to think outside the box when it comes to energy production. There are a million sources of clean, environmentally conscious power all around us, we just have to explore and utilize these sources in the most efficient manner possible. Ambient energy capture will no doubt play a large part in the future of renewable energy, and there's no time like the present to work on developing new, innovative means of electricity generation. I feel confident in saying that the world of tomorrow looks pretty bright, both literally and figuratively.

Laptops in the Classroom Essay

Today’s technological advances are ever-changing our world, making life â€Å"easier† and more convenient. Tasks that once may have taken hours of notes, reading and organizing the many pages of documents, can now literally be accomplished in minutes with today’s portable computers. Most would agree that in our learning institutions laptops have become an essential tool in the success of students. Where this agreement usually ends is on the question of the use of laptops while in the classroom. On the one hand some would argue that the use of laptops allow students to research information on the fly, and to take notes, having them neatly organized and even saved to a central database to make them easily accessible by any internet connected computer at any location. On the other hand, some say laptops lead to unnecessary interruptions and disturb the instructors and students alike. My own view is that laptops disrupt the class in many ways and should not be allowed in the classrooms during instruction. First of all, while in class or lecture, the constant clicking of the keys can prevent the instructor from being heard, especially when there is more than one or two keyboards clicking away. Also, the brief seconds that your mind lends to focus on the operation of computing could possibly the moment that a student misses key information. And there is a disadvantage to not giving your undivided attention to an instructor’s lesson, on a larger scale this becomes an obstacle for  McLemore 2 effective learning. As noted in an article, Laptops in Class: A Professional Virus by Maureen A. Howard: Our brains just aren’t designed to do multiple tasks simultaneously and do them well. Admittedly, I can agree that laptops provide many advantages for students including consolidating and organizing multiple subjects. But as I stated before, the operation of laptops in class can be a distraction, and at which point does that distraction become too much to be allowed? Having laptops in class brings up the issue of browsing the internet, playing games, communicating, or the great many other things that one could do, other than following along with the class instruction. Furthermore there is a potential for theft and damage to students property, which could also lead to students arguing and possible physical altercations. All of which impede the progress of learning in the classroom environment. In addition, one should also consider that the traditional method of taking notes by hand and later transferring those notes to a laptop also gives the student the opportunity to go over that information once again. This process helps students commit the information into long term memory. In conclusion, I believe that the negative aspect of using personal laptops in the classroom environment far outweighs the positive reasons to have them, and thus laptops should not be allowed in the classroom during instruction.

Hotel Ratings in the Modern World

Hotel Ratings in the Modern World Introduction Looking at the modern industry of hospitality, the hotel ratings seem too strange and unreliable. Having visited many hotels, I may say that there are a lot of those which do not correspond to the real estate of things. Having read two articles about hotel ratings, I should say that the modern system of hotel ratings is too poor and does not nave any reliable grounds.Advertising We will write a custom essay sample on Hotel Ratings in the Modern World specifically for you for only $16.05 $11/page Learn More Neither the rating which is given by the credible magazine which tries to follow the international standards nor the one presented by those who have visited the place can be trusted as most of the comments are left by the professional writers who are paid for a rating to make people believe that the place is good enough. There is also no guarantee that a hotel rating presented by a reliable company which is responsible for creating the rating is objective as all people do in the modern world are subjected to business relations. Body Hotel business is one of the most important ones as accommodation is the central aspect in the global political and economical relations in the world. Each company tries to be responsible for the ranks it gives, however, being based on the business relations there is no guarantee that the hotel is ranked adequately and no business relations are involved. Looking at the present situation in the accommodation business, the following aspects are to be considered. First, hotels want to get as many customers as possible, therefore, the marketing and promotion strategy is usually on the high level. The hotels create websites where people seem to express their opinion. However, in most cases professional writers leave comments. Of course, people are able to do it as well. One may come across several negative feedbacks, but a clever client would think that they are just the personal opinion of those who are always unsatisfied with everything as the vast majority of the feedbacks are going to be positive. Second, there are many companies which guarantee to provide hotel ranking services having compared and contrasted the hotel’s services with the standards and to draw the conclusions. However, the absence of any internationally accepted standards makes it possible for the companies to vary in their opinions. The business relations are based on the financial grounds, therefore, the companies get money and give a hotel rating it wants. Finally, hotel business is very competitive. The Internet has become the most important means of advertising. Many people in the world use the Internet for all needs and the information search is one of the main functions the Internet performs. Having understood this idea, many hotel promotion programs became to be oriented on the customers’ feedback. Conclusion Therefore, it should be concluded that hotel ratings in the modern world a re created just with business purposes and some of the hotels do not correspond to the level they are ranked with. Being positioned as 5 star hotels, most of the accommodation services are not that perfect as they are to be.Advertising Looking for essay on business economics? Let's see if we can help you!

Synopsis of a Contemporary Strategic Issue Essay

Synopsis of a Contemporary Strategic Issue - Essay Example innacle of Japanese innovation, very recently, Toyota has had to recall 8m vehicles due to â€Å"unintended acceleration† (The Economist, Feb 11, 2010). Toyota Prius (the hybrid vehicle) has developed problem with brake pedals that refuse to open (The Economist, Feb 9, 2010) and 440,000 vehicles would have to be called back. The firm’s reputation for quality on which the organization was built has been shattered. Toyota is busy chasing volumes at almost any price. Its global market share has fallen to 11.8% from 13.1% (Appendix A). The business environment is currently turbulent and according to Ansoff, to survive and succeed in an industry the firm must be able to match the aggressiveness of its operating and strategic behaviours (Thompson & Martin, 2005). The business environment is characterized by several factors and the resources of the organization and the values must be congruent to the needs of the environment. Changeability of the market environment- the current market is turbulent due to global economic downturn. Besides, due to the large amount of vehicle recall, Toyota’s market capitalization has dropped. The cost of recall is $2bn dollars (The Economist, Feb 9, 2010). Globalization, individualizations, digitalization and increasing competition have increased the speed at which change is taking place in the industry (Jain & Garg, 2010). The car makers can now expand to new markets a fast pace. Fertility of technology: The firm has always prided itself in being leaders in innovation but the cars rolled out recently have problems with brakes. The floor mats are badly fitted. All these suggest that the organization has to rethink its outsourcing policies. Toyota has depended on several layers of suppliers which has helped them to reduce the costs (SD, 2006) but they need to take note that most of the accelerator pedals were supplied by American parts-maker (The Economist, Feb 11, 2010). However, many automakers use the same suppliers and a domino

Marketing - Essay Example Marketing also includes system of management that identifies, anticipates and supplies customers’ requirements efficiently and profitably. Marketing objectives rotates around meeting the needs and wants of customers. It is an organization broad activity that involves a process of keenly analyzing customers’ needs, and getting ways to provide goods and services to meet those needs. Effective marketing does not only provide customers with products and services, but also successfully provides changing benefits to the changing needs and demands to various consumers (Stahlberg, 2009). Elements of Marketing Concepts Marketing concepts introduces new requirements to the product development process.

Consumer Psychology Mostly every facet of marketing is guided by consumer psychology and behavior. Marketers have realized that consumers can be driven by advertisement in making a decision on what to purchase. They have identified that a desire for a service or product can be kindled in a customer who w ould otherwise have no such desire. This has influenced marketers to keenly developed advertisement that have a psychological and emotional impact to the consumer (Sullivan & Adcock, 2002). III. The Marketing Mix This involves all elements of marketing. Some popular components of the marketing mix are; advertising, sales, promotion, public relation and to some degree product development. Characteristics of Marketing Oriented Organization The main purpose of marketing oriented company is to ensure that they keep a close relationship with their customers. This gives the company competitive edge to stay ahead of their competitors. Some of the distinctive features that define marketing oriented organizations include; shared values, organization, stakeholders and ultimately policy. All the decisions made by this business oriented organizations should consider the customers demand first. They should ensure that they share common values of high quality products with the customers. These or ganizations also have few levels in their organization structure. Their policies are clear and unambiguous to understand and apply. They always have a long term strategies that are flexible and participative. These companies always put stakeholders’ expectation first before they begin to make some critical and dynamic organization decisions.
