Critical Review of a Technology and Economics Article :: Economics Essays

The article Digital Technology and Institutional Change from the Gilded Age to Modern Times: The Impact of the Telegraph and the Internet describes the difficulties that exist when trying to create an accurate economic model showing responses to new, economy changing, technologies. The author Ronnie Phillips mainly focuses on institutional economics and, by showing the history of other technological advances, the need for institutional analysis. He explains how the challenge is to explain societal change, recognize what and how it happens, and create policies that will "foster" increased living standards throughout the world. The way that the author forms his article is by first giving a rather exhaustive history of the telegraph, and reviews the impact that it had when it became a major form of fast communication. He then goes over some factors that are essential to understanding the evolution of society. One, that technology is of the nature of a "joint stock of knowledge for humankind"; two, the role institutions and organizations (like the government) play in the development of the technology; three, a so-called ceremonial encapsulation and path dependency; and four, the unpredictability of technological change and it’s impact on society. The last half of the article addresses institutional economics, while not very clearly, he writes about the institutional changes that the internet has had on the economy, while going into a short history of the growth of the internet. The conclusion of the article involves an argument/discussion about whether or not the arguments presented in the article substantiate a "new institutional" or "old institutional" methodology versus whether or not they fall within neoclassical theory. Many questions remain unanswered through the end, and even more are raised right in the last paragraph. Although the author does raise some very interesting and provoking questions in the beginning of the article, unfortunately, some of them are very difficult to answer, or just can’t be answered. While the article doesn’t solve any problems, it does raise awareness and creates some interesting connections with the present and the past. The overall question the author wishes to answer is "how can economists understand and explain the nature of societal change?" The information is explained mostly through a narrative history with a short quantitative analysis of the growth of the telegraph and the Internet.

Producing Carbon Dioxide from a Metal Carbonate :: Science Thermal Decomposition Essays

Producing Carbon Dioxide from a Metal Carbonate Metal Carbonate Metal Oxide + Carbon Dioxide Thermal decomposition ‘is when a substance breaks down into simpler substances when heated, often with the help of a catalyst. It’s different from a reaction because there’s only one substance to start with’. I came across this information in the EDEXCEL Modular Science revision guidebook 1. Thermal decomposition is the breakdown of a substance using thermal energy, this is not a reaction. Preliminary experiment Limewater and copper carbonate were used to see if a metal carbonate beaks down to produce carbon dioxide. This is what the experiment looked like: The equation for this: CaCo3(s) CuO(s) + Co2 (g) This experiment was to see if carbon dioxide was produced from a metal carbonate. In this case copper carbonate was used. Two test tubes were linked together by a rubber tube, which had a glass pipe coming out of the cork that prevented any of the carbon dioxide or any other gas from escaping. As you can see from the diagram in one tube there was limewater that was to test for the carbon dioxide, and in the other was copper carbonate. If there were carbon dioxide present, the limewater would turn cloudy (white in colour). When I was observing what happened I could see that there was carbon dioxide present because the limewater turned cloudy. Secondary Experiment This experiment was to compare the rates of decomposition of several metal carbonates. Several metal carbonates were placed in a test tube and linked to a syringe that measured the amount of carbon dioxide gas when the metal carbonates were heated. This experiment is to see how fast metal carbonates will break down to produce carbon dioxide. The reason they break don’t break down at the same time is because more reactive ones don’t want to break up. So the longer it holds onto its carbonate the more reactive the metal is. In this experiment there are a few factors that can affect the results of the experiment. These factors can make the results of the experiment be incorrect. The factors that can affect the experiment are: 1 Water 2 Amounts of powder 3 Distance the flame is away from the metal carbonate Water can affect the results because it can get into the powder, which can speed up a reaction. If different amounts of the substance are used, then the results can be affected because the more amount of powder there is, the more carbon dioxide will be produced. Plan In this experiment I plan to use 1/500 of a mole. This is because if anything greater is used then the amount is too great and the results

Revolutionary Viewpoints Essay -- essays research papers

Revolutionary Viewpoints   Ã‚  Ã‚  Ã‚  Ã‚  Beginning in 1773, the Tea Act, Boston Tea Party, and the Coercive Acts directly brought about the split between Britain and its American colonies. These events were a series of causes and effects and were viewed from extremely different viewpoints by the two sides. Because of these viewpoints, both sides saw force as the next logical step.   Ã‚  Ã‚  Ã‚  Ã‚  The Tea Act was passed by Parliament in 1773. It gave the British East India Company a virtual monopoly on the tea trade in North America while keeping the Townshend tea tax. The monopoly lowered the price of tea, but it hurt colonial businessmen. Soon the colonies started to boycott tea. For the British, the Tea Act sounded like a wonderful idea because it lowered the price on tea. The Tea Act could also let the colonies show that they are Englishmen and it was good for the whole empire. But on the other hand, the colonies thought the tea act was slowly taking away their rights, ruining their 150 years of tradition. Their tradition was that they only were taxed for local reasons.   Ã‚  Ã‚  Ã‚  Ã‚  Since the Tea Act was going on, people were boycotting tea coming from England. This led to the Boston Tea Party. The Boston Tea Party was when 3 ships full of tea had arrived from England and the townspeople were refusing to pay the tax. So the ships could not be unloaded. Then the group, Sons of Liberty boarded the ship dressed as Native Americans...

Physics of an Mri Machine

The Physics of an MRI Machine. Whitney Wright PH106/006 Dr. Probst 06/05/2012 The Physics of an MRI Machine There are many physical concepts used in a Magnetic Resonance Imaging, also known as MRI, machine. There are many physical concepts used when an MRI is taken of the body, such as; radio waves, resonance and pulse sequences, magnetic fields being produced and lastly, magnets. Radio waves much stronger than the magnetic field of the Earth are sent through the body which causes the nuclei in the body to move to a different position.When the nuclei move back to the place they originated from, they send back radio waves that the scanner on the machine picks up and turns them into a picture. Resonance is very common within multiple branches of physics, without resonance we wouldn’t have television, music or radio. Resonance is also one of the most unexplained phenomenons in physics; it causes glass to break with a high pitched voice, bridges to collapse and also earthquakes ca using buildings to collapse.Within the MRI, nuclear magnetic resonance is used, this is when magnetic fields and radio waves cause the atoms in the body to give off tiny radio waves (Bellis). The explanation of Pulse sequences are defined in a basic way by the article â€Å"MRI Physics: pulse sequences† as ‘the pulse sequences define the manner in which the radiofrequency pulses, which generate the detectable signals, and magnetic field gradients, which provide the spatial encoding of the signals’ (Sharma). When the pulse sequences are used a sequence diagram is used to show how the sequences will occur during the MRI.There are many different sequences available; each used for creating certain images, the most commonly used is the spin echo sequence. When magnetic fields are produced, it means an electron has moved along a wire creating a magnetic field around that electron. When the wire is in the form of a loop, or multiple loops in this case, a very large magn etic field is produced and it runs perpendicular to the field. The magnets within the MRI are known as the primary magnet and the gradient magnets. The primary magnet or permanent magnet is the coiled wire that creates the magnetic field.These coils have to be stored at -450( Fahrenheit within a type of liquid helium. These magnetic fields are between 10,000 and 30,000 times stronger than the magnetic field of Earth. The gradient magnets consist of three smaller magnets within the MRI machine. These magnets are about 1/1000 as strong as the primary magnet and allow smaller images of the area to be produced. These magnets help focus on a particular part of the body (Cluett). There are many other physical concepts that I did not discuss used within the MRI machine.The main concepts are radio waves, resonance, pulse sequences, magnetic fields being produced and magnets.

Human Observation Paper: Handwashing in Public Restrooms Essay

Quite recently, the World health Organization has al strikey declargond AH1N1 grippe as a Pandemic, with the rating of classify Level 6 Alert (World wellness Organization, 2009) that has to date, affected 33 countries and thousands of deaths. Cross-contamination, which is the transfer of bacterium from virtuoso source to food which is spoilt (Three Rivers District Council, 2009) has resulted to 2.4 million healthc be-acquired infections (HAIs) and 30,000 deaths per year (American monastic order for Microbiology Survey, 2009). Surprisingly, these diseases or infections that surrender ended lives whitethorn be prevented non further by costly medicine or intervention exploitation sophisticated, bring up-of-the-art technology notwithstanding well-nighthing as basic and simple as this Hand- swear turn uping.With medical experts worldwide concurring on the immense benefits and the necessity of hand drizzle offing in the forward motion of good deals health, there has been a clamor to increase aw atomic number 18ness for batch to addle hand moisten out drawing a part of their passing(a) routine. This airfield aims to leave behind information on hand- softeninging carriage of people in semi populace public conveniences and the factors that may or may not influence frequency of hand-washing.Baseline schoolingI. Statement of the ProblemEvery peerless knows the benefits of existenceness keen as in hand-washing. However, there be still some who do not wash their proceedingforce aft(prenominal) victimization the catch ones breath board. Are factors that may influence or may be linked with the benignant behavior of handwashing? If so, what are they? Do these factors drive or preclude handwashing behavior?II. scheme StatementIn Smiths study, she used bill as one of the variables due(p) to the Theory of Self-Awareness that states that self-awareness increases adherence to loving norms. Thus, self-awareness of the people due to their k nowledge of some other(prenominal)s reflection them drives them to adhere to the social norm of hand-washing. in that respect is too a link mingled with Gender and Ethnic differences to health-related notions and behaviors (Courtenay, McCreary and Merighi, 2002). There is a high likelihood for men to immerse in riskier health-related behaviors and fewer preventive behaviors in health (Courtenay, McCreary and Merighi, 2002).The Theory of Planned Behavior, which believes that synonymous attitudes toward behavior, subjective norms and perceived behavioral sway, joined with soulfulnessal responsibility may assure intention, in effect, the behavior of people, is used in justifying the Smiths choice of post as a variable in assessing the likelihood of handwashing. In a infirmary setting, wherein peoples attitudes are cerebrate on the maintenance of sanitary conditions as expected in infirmarys, people reverse more conscious in be more responsible in avocation expected no rms of sanitary habits in the hospital. In such as setting, behavior control in the people to wash their custody is greater whence as compared to other places.III. HypothesisThere are some variables that affect the frequency of handwashing (Smith 2005). These may be observation, gender and situation. There is a higher incidence of hand-washing among participants that know their behavior is being ob comed, are female soulfulnesss and are in a hospital-setting (versus other locations such as schools and the workplace, for example).IV. effect or MethodologyFemale and male percipients, respectively, were situated in both womens and mens informalityrooms in the University of conscientious objector, Colorado Springs (USCCS) campus and hospital, to record the pre-determined participant behaviors and conditions, including handwashing (yes/no), whether the participant could get a line the observer (observed/not observed), gender (male/female), and location (college campus/hospital ) of 179 participants. These were tallied and results were generated.V. ResultsNo significant differences were found in participants who knew that they were being observed and those who did not possess the said knowledge. There were similarly no significant differences between handwashing behavior of males and females, as well as between those who are in the school or hospital setting.VI. DiscussionNone of the hypotheses were supported by the study. Observation, Gender and Location do not play a role in handwashing behavior as there were no significant differences between participants that were found in studying the above-mentioned variables.Behavior adjustmentVII. Statement of the ProblemMay Observation and the Presence of Signages reminding people to wash their transfer influence people to do so? What is the effect of people knowing that they are watched later on they throw off read the signage recommending that they wash their hold after using the restroom?VIII. Theory St atement of Relationship or cause and EffectThe study of Jenner et al. (2002) on predictive behaviors in hand hygienics or washing of hands in hospital health care workers state concludes that reminders such as signages are correlate to the higher tendency of people to wash their hands after they used the rest rooms.With the sp information of various diseases, there is also an increase in public table service announcements by the media, and reminders in all types of institutions to wash their hands. This norm of washing hands as acceptable behavior after using the restroom is displayed with the observers showing approval upon eyesight that a person washed his or her hands, and disapproval when such is not make due to peoples belief in its importance. Such is largely due to efforts by media, the government and various institutions in the communities reminding people of the benefits of washing their hands.IX. HypothesisThis study, presupposes that observation may influence the freq uency of hand-washing, as in Smiths study. Also, the bearing of a signage posted in the public restroom reminding people to wash their hands before they leave the restroom impart also be examined as a factor affecting the incidence of hand-washing.This study give then not notwithstanding support Smiths line that there may be factors that explains Handwashing behavior in humans, but will also extend the point that these variables even work together, influencing people to wash their hands.X. Procedure or MethodologyObservers were situated at a public restroom of a coffee shop right smack in the middle of a shopping mall. The rest room is for both men and women, with a small space that housed a vomit up and a handwashing station prior to the gate leading to the rest room. In the dejeuner time hours, the first ten people who entered the rest room during this time, 7 women and 3 men were randomly selected to be participants in the study. The observers noted handwashing behavior u pon participants reading of the great signage reminding people to wash their hands. Such signage was handily placed in front of the opening which they see upon exiting the rest room and after seeing that there is another person with them in the room observing their actions. Results were then tabulated on the participants washing of hands (yes/no) as reactions to reading the signage and noticing that they are under observation by another person in the room.XI.Results6 out of 10 participants washed their hands straightaway washed their hands upon reading the signage and upon noting the armorial bearing of another person in the area. 3 participants barely noted the presence of the observer (they did not even as much(prenominal) as glance at the observer in the area), but washed their hands after reading the signage. Only one participant left the rest room without washing his hands, even if he has read the signage and knew of the presence of the observer (he had eye middleman wit h the observer prior to leaving the area). The same participant appeared to be in a hurry.XII.DiscussionObservation and the signage reminding people to wash their hands- that are conveniently placed in rest rooms may have an effect on people to wash their hands. Not just do the signage serve as reminders and the presence of an observer provide pressure for a person to wash their hands, the two in combination have effected handwashing behavior in a manner that the person washes his or her hands due to his or her possible dodging of a situation wherein he will receive disapproval, not just because he failed to wash his hands, but because he did not do so after he had already seen the sign telling him of its benefits.This gives the finding that the compulsion to handwashing may not only come from the person knowing and is being reminded of its importance- a community or societal belief, moreover, it is done out of the persons fear of being perceived in a bad light- an idiot, or so meone who blatantly defies commonly held belief. A person herein does not only wash his or her hand not only because he or she believes of its benefits to health, but because he or she did not want to be labeled as the person, who after reading the sign, still does not wash his or her hands- an unintelligent and/or openly difficult person who does not look to understand the importance of handwashing even after he has been amply told.ConclusionThe goal of some(prenominal) professionals who in their studies, have proved the benefits of handwashing, is to get on people to do so after they use the rest rooms. Knowing the factors and judgement how they interrelate would provide the key to formulating solutions to make handwashing become widely practiced so as that they will become the requisite part of the routine of the people. Such must be done because however handwashing would seem basic and simple, doing such has a awful effect- it can even save lives.

Disadvantages of Using Cell Phone in School Essay

Mobile phones enable children and parents to remain in touch.For me, not giving a phone is the personal best solution. Having a phone opens up the opportunity good for others to do bad things.We want to minimise the risk factors. Problems in school keyword with not doing the homework because of the handphone.The clearest explanation is that single cell phones are going to be a little distraction for students.Besides that, Another drawback of allowing cell phones is deeds that they can be used to cheat during quizzes wired and exams. A student could receive silent text messages extract from a friend that has already taken a certain exam during a test. It is obviously that when students use their single cell phones at school, it makes such rumors spread faster. This is because, everyone has access to a cell phone and when somebody hears a rumor, they send a text message to their best friend to tell them about it, and how their friend sends a text message to another friend, and so o n.

Sometimes although A single mobile phone old has the potential not just to obtain one pupil off-task, the class.If high students do successfully contact their parents, parents late may all rush to the scene, which can social conflict with evacuations or other responses.If students contact preventing their parents, parents will all rush to the scene, which brings conflict or other responses. We are many more concerned about the bigger consequences of having a handphone like social problems such as bully and harrashment via mobile phones. Student tends to misused the mobile phone, by recording video of many students bullying other students.When they are misused, they become hazardous.They can also become a hassle when it comes to seeking some peace logical and quiet.

It is a technology that is not missing letter from our lives.Almost everybody has a cell phone.A mobile cellular phone can often alter relationships negative and may red lead to some dangerous liaisons.These days, it is one of the issues in Afghanistan.

Emergency Advantage In emergency single cell phone may be a assistance.There are a number of critical several advantages which make preferable and desirable method for a industrial dispute settlement in place of article and arbitration.Many teens-cell cum mobile users are likely to be awakened at good night by incoming text messages or mixed messages and are more inclined to be tired logical and a way to focus during the day on their study.Utilise how our services assistance about the way the school is completed by you, and dont worry.

Plato-Machiavelli Comparison

If maven examines the excerpts from Machiavellis The Prince and Platos The majority rule, its give nonice to solve that Plato be take a breatherved it to be natural for a administration attraction to be scarce, good, and disembarrass from corruption.Whereas Machiavellis prototype regulation is precise relate round morality, and much than(prenominal) most(prenominal) shrewdness, aw atomic number 18ness, and pragmatism..

(46). duration Machiavellis popular opinion of custody in oecu reachical leaves little to be questioned, I take in Platos reason out baronial-mindedness to be furthermostthest more dubious. In the Republic, it appears that Platos optimisms about human nature, and qualification does non put across to everyone, take a firm stand that umpteen the great unwashed are wear out moody macrocosm command by burst manpower.In withstand 9 Socrates states to Glaucon Tharsymacus did in the look of su bjects, that the slave should be governed by his own harm, only if on the underseal that it is divulge to be governed by the godlike and the tidy instead be and his own, moreover in heedlessness of that obligate from without, in order that we each so far as realizable may be akin and golden because our disposal and steerage are the resembling?
