A Memorable Experience in Photography To experience photography, one must have a certain style of photographs to really appreciate or admire. Photographs are picturesque images and views that really catch the interest of the photographer. For me to experience and admire photography, it took me only one photographer to really appreciate the power it has his name is Robert Capa. Robert grew up in Hungary he experienced the political unrest and turmoil. He lived under the oppression of Horthy and knew the kind of anarchy that constitutes war(Images of War 8). Robert's work represented 3 categories: 1. Images of battle. 2. Images of the effects of war. 3. Images of calamity(Photographs,Introduction). His work also had a swift understanding and sympathy for the people who suffer from being caught in war. This type of suffering made it impossible for him to ignore the events which affected their lives(Images of War 9). Robert's belief on photography is "If your pictures are not good enough, your not close enough"(Photographs Foreword). Robert's breakthrough in the field of photography came during the Spanish Civil War. His most famous picture was a snapshot of a courageous man in the act of falling(Capa18). His own special talents and course of world happenings, led him into a role as a professional photographer of war(Images of War20). To really admire and understand Capa, you must have a fascination for dramatic and emotional pictures of war. There probably has been thousands who admire the work he does. Well you can include me in that group of thousands. Capa puts into perspective in just one photograph, something my grandfather will never forget. The Bombing of Pearl Harbor. The photograph that brings back these memories is taken somewhere in Europe during World War II. It's a photograph that has the air full of scores of Japanese warplanes. They are flying over war stricken farmland. As an American citizen, this photograph brings a lot of emotions through me and would have brought greater emotions to my grandfather. I used this photograph because it brings back the memory of my grandfather telling me the story of how he survived that tragic day. On December 7, 1941, my grandfather was stationed at Pearl Harbor as a airplane mechanic. It was still early in the morning and he was still sleeping. Then out of nowhere he heard numerous explosions and then the sirens went off._ _He rushed out of bed and ran upstairs to see what was happening. In the sky he saw scores of Japanese airplanes flying and bombing the area. Some of the airplanes would risk their own lives to do more damage to the ships and the

H202 Decomposition

Hydrogen Peroxide Decomposition Reaction Kinetics Purpose: In this experiment, you will determine the rate law and activation energy for the iodide-catalyzed decomposition of hydrogen peroxide. Overview: The decomposition of hydrogen peroxide is catalyzed by iodide according to the following reaction: 2H2O2 (aq) [pic] 2H2O (l) + O2 (g) The speed of the reaction is determined from the reactants being consumed or from products that are being formed. This must be determined experimentally by measuring the rate of change in the concentration of one of the reactants or one of the products.The change of concentration can be measured by such physical properties such as the volume of a gas or color intensity of a solution. The rate may be expressed, for example, as moles per liter of product being formed per minute, milliliters of gas being produced per minute, or moles per liter of reactant being consumed per second. During this experiment, you will determine the rate of decomposition of hy drogen peroxide in the presence of a catalyst, iodide. The goal in this experiment is to deduce a rate law for the reaction, showing the dependence of the rate on the concentrations of H2O2 and I-.Your rate law will be of the form: -[pic]= k[H2O2]x[I-]y k is the reaction rate constant and depends only on temperature. x is the reaction order with respect to the hydrogen peroxide concentration and y is the reaction order with respect to the iodide ion concentration. Your objective is to determine the numerical values for the exponents x and y and rate constant, k. You will also study the effect of temperature on the reaction. Materials: 0. 25M KI solution 3% H2O2 solution distilled water 125mL or 250mL Erlenmeyer flask 50mL gas collection tube ring stand test tube clamp one-hole rubber stopper eaker water bath 50mL graduate cylinder 5 and 10 mL pipets thermometer Procedure: 1. Fill one beaker about half full with water. Fill the gas collection tube with water and invert into this beak er. Clamp the gas collection tube to the ring stand. You will use this to measure the volume of gas generated in the reaction. 2. Place the Erlenmeyer flask into a water bath. Fill the waterbath two thirds full of water. Record the temperature of the water. Cap the Erlenmeyer flask with a one-hole rubber stopper. Insert a short piece of glass tubing into the one-hole rubber stopper.If necessary, cut a piece of glass tubing and fire polish the ends. Connect one end of the rubber tubing to the glass tubing and insert the other end into the gas collection tube. You are now ready to start the reaction. 3. Remove the rubber stopper from the 50 mL flask. Add 10 mL of the 0. 25 M KI solution and 15 mL of distilled water to the flask. 4. Add 5 mL of 3% H2O2 to the Erlenmeyer flask. Swirl to mix the solutions and immediately replace the rubber stopper. Begin taking oxygen volume readings immediately. 5. Record the time and oxygen volume (mL) every ten seconds for 240 econds or 30mL (whicheve r comes first). Swirl the flask during the reaction to prevent the solution becoming super saturated with oxygen. 6. Repeat the experiment, using a clean flask, with10mL of the 0. 25-M KI solution and 10mL of distilled water, then adding 10 mL of the 3% H2O2. 7. Repeat the experiment again, this time using 20mL of the 0. 25-M KI solution and 5mL of distilled water, then adding 5 mL of the 3% H2O2. 8. Replace the water in the water bath containing the Erlenmeyer flask, with water that is 10-20(C warmer than previously used.Repeat the experiment using 10mL of 0. 25M KI, 15mL of distilled water and 5mL of the 3% H2O2. 9. For each of the three trials, plot the volume of oxygen in milliliters versus the time in seconds. Fit the data with the best-fit curve or straight line for each trial, ignoring the first sixty seconds of data. (Do not draw a line that connects point to point. ) 10. Calculate the slope (mL/sec) of each line. The slope of each line gives the rate of oxygen production in mL/seconds. 11. Use the slopes and the details from each trial to determine the reaction orders for the I- and H2O2.Note that the KI and H2O2 volume are proportional to their concentrations in the reaction solution. | |Slope (mL/sec) |KI |H2O2 | |Trial 1 | |10mL |5mL | |Trial 2 | |10mL |10mL | |Trial 3 | |20mL |5mL | 2. Calculate the rate constant, k, for the equation: -[pic]= k[H2O2]x[I-]y Substitute values for [H2O2], [I-], x,y and -[pic]/[pic]into the equation and solve for k. Use the reaction orders determined above for x and y. Using data from one of the trials, calculate the molarity of the H2O2 and I- in the reaction solution and the hydrogen peroxide disappearance rate. Use these values to substitute into the above equation. You can determine the hydrogen peroxide disappearance rate from the rate of oxygen production.Convert the rate of oxygen production to moles per second using PV=nRT. Remember to reduce the pressure of the oxygen by the water vapor pressure. Use stoichio metry to convert moles of oxygen to moles of hydrogen peroxide. Use the solution volume to convert the moles per second to molarity per second. Calculate the rate constant, k, to two significant digits. Be sure to include units. 13. Examine your results to determine the effect that temperature had on the reaction rate. 14.Calculate k for the higher temperature, and, using both k values determine the activation energy for this reaction[1]. Questions: 1. How would your calculated reaction rate constants and calculated activation energy have been affected if the nominally 3% hydrogen peroxide had a concentration of only 2%? 2. How would your results have been affected if extra water had accidentally been added to the reaction mixture? 3. If you do not agitate the reaction solution, it can become supersaturated with oxygen. How would this affect your results? . If you had been able to directly determine the concentration of hydrogen peroxide in the reaction solution, you would have been able to graph the concentration versus time. What would that graph look like? 5. If you had been able to directly determine the concentration of iodide in the reaction solution you would have been able to graph its concentration versus time. What would that graph look like? 6. What would you graph versus time to determine the reaction rate constant? How would you calculate k from the graph? dapted from a lab at Occidental College http://departments. oxy. edu/tops/Kinetics/kinetics. pdf ———————– [1] Activation energy, Ea, is related to the reaction rate constant, k, by the Arrhenius equation: k=Ae-Ea/RT. R is the ideal gas constant, 8. 314510 J/(K†¢mol). A is the frequency factor with units of L/mol†¢s, and is related to the fraction of collisions that have the correct geometry. The activation energy can be determined using reaction rate constants from two different temperatures using the Arrhenius Equation rearranged as: ln k2 – ln k1 = – [pic]

Drug Abuse as a Social Problem Essay

Drugs have been around for thousands of years. â€Å"A drug is any chemical that produces a therapeutic or non-therapeutic effect in the body (Drugs and Teen Substance Abuse 2000.)† Most drugs were first used for medicinal purposes, such as marijuana. Active substances were not extracted into drugs until the 19th century. Newly discovered substances like morphine, laudanum, and cocaine were completely unregulated and prescribed freely by physicians for a wide variety of ailments. Wounded veterans returned home with their kits of morphine and hypodermic needles (History of Drug Abuse, n.d.) The use of illegal drugs is increasing, especially among young teens. The conflict theory of social problems states that, â€Å"society is marked by conflict due to inequalities in class, race, ethnicity, gender, age, and other divisions that produce conflicting ideas (Kornblum and Julian, 2004, 7.)† Solutions to solve social problems include building stronger movements in conflicted groups and then possibly engaging in negotiations to reach accommodations. The functionalist approach to social problems, â€Å"views society as a vast organism whose parts are interrelated (Kornblum and Julian, 2004, 7.)† Functionalists believe that institutions produce patterns of deviance and they must be addressed through well-calculated social reformations. Solutions include engaging in research and interventions to improve these social institutions. There are many ideas between the conflict and functionalist perspectives on how to remedy the wide-spread social problem of drug abuse. Substance abuse can simply be defined as, â€Å"a pattern of harmful use of any substances for mood-altering purposes (What Is Substance Abuse, n.d.)† As culture and customs change, so do the major categories of illegal drugs. The most commonly abused drugs today, in addition to alcohol, are marijuana, cocaine, opiates (including heroin and morphine), hallucinogens, amphetamines, and barbiturates. Some young people are again experimenting with psychedelic drugs like LSD and Ecstasy (Kornblum and Julian, 2004.) Teens use drugs for many reasons including curiosity, because it feels good, to reduce stress, to feel grown up or to fit in with their peers (Drugs and Teen Substance Abuse 2000.) Many people view drug abuse and addiction as strictly a social problem. Drug  abuse affects society in many ways. In the workplace it is costly in terms of lost work time and inefficiency. More than half the deaths in the United States involve alcohol, in some form, such as in homicides and suicides. Drug-related crimes can disrupt the neighborhoods due to violence among drug dealers, threats to residents, and the crimes of the addicts themselves. Also, a great majority of homeless people have either a drug or alcohol problem (NIDA InfoFacts: Understanding Drug Abuse and Addiction, 2005.) Humans have used drugs of one sort or another for thousands of years. For the past last decades, crime and drugs have been called by some, the most important problems facing this country. The full economic cost of drug abuse in the United States is estimated at approximately $70 billion annually. In so, America is actually losing money because of the use of drugs. Due to years of studies, it is proven that drug abuse costs the Organization for Economic Co-operation and Development (known as OECD) countries more than $120 billion per year in drug enforcement, prosecutions, prisons, prevention programmers, treatment and health care costs, and financial losses incurred from drug-related crimes. This is very bad for the community as a whole because it also affects many people. In a present study, it was hypothesized that the likelihood of recent hard drug use would be higher among arrest. They have a slight disadvantage because of low income, widespread poverty, high employment rate, lim ited high school graduation, numerous female-headed household, high population density, and large African-American population. The sociological Conflict Theory holds that there are higher numbers of chronic drug abusers found in lower social classes, disorganized neighborhoods, and relatively politically powerless places. The disappearance of decent paying manual work since the early 1970’s leaves unskilled, uneducated individuals vulnerable to poverty. This is when selling drugs, an alternative to enduring grinding poverty, has been a common enough response as the income gap had widened. This has increased the violence and crime rate of society. The Functionalist Perspective in sociology states that everyone in the society holds a position and in this position their status has a set of  roles or certain behaviors that are required to perform the tasks at hand (Kornblum and Julian, 2004.) The roles consist of nurses at the medical institutions, lawyer’s at international firms or just a blue collar worker at any type of factory. For the most part, each status’ role is involved in an institution of some kind and is needed for the economy and society to function as a whole. â€Å"The Functionalist Perspective looks at the way major social instructions like the family, military, the health-care system, and the police and courts actually operate (Kornblum and Julian, 2004, 6.)† This basically means that for these institutions that are needed to fulfill these roles and duties for the economy, the roles and behaviors of employees need to evolve as a whole so that the institution can function (Kornblum and Juli an, 2004.) For example, a nurse needs to know certain things about her job like what medicine can treat a certain sickness or when and where CPR is needed for a victim or if moving that victim could paralyze that person. Sociologists say that, â€Å"when all members of the group perform their roles correctly, the group is said to be functioning well (Kornblum and Julian, 2004, 6.)† When society as a whole is said to be functioning as â€Å"one† this means that â€Å"there is general agreement about how roles are to be performed and the expectations are reinforced by the society’s basic values (Kornblum and Julian, 2004, 6.)† The main question that is asked is, â€Å"why do we have social problems if each institution has roles in the society? (Kornblum and Julian, 2004, 6) † Many say that the main reason that functionalists believe we as a society have social problems is because our society is always changing and the society is having to adapt to the changes and when the society fails than that is when social problems exist (Kornblum and Julian 2004.) When a society undergoes changes, for example going from pre-industrial where most of the economy was based on agricu ltural to the industrial era where many poverty stricken’ farmers became factory workers but of those workers do not adapt, it is said that such a change can lead to crime, such as drug abuse. The functionalist sociologist says that, â€Å"all societies produce their own unique form of crime and how they respond to this change (Kornblum and Julian, 2004, 7.)† In the past years we have been fighting a war against drugs. In the mid 1980’s, the United States adopted a series of aggressive law enforcement  strategies and criminal justice policies geared towards reducing and punishing drug abuse. Changes in the federal laws required that all sentenced federal offenders were to serve 87 percent of their court-imposed sentence. Many drug offenders are subjected to a mandatory sentence based upon the type and quantity of the drugs that were involved in their arrest. According to the Uniform Crime Report, 1,532,000 drugs arrests were made in 1999, up from 580,900 in 1980. Some people think the increase in drug arrests is a good sign, but others think it denies drug users what they really need, which is treatment. No one seems to argue about the serious problem with drugs in the United States. According to a 2002 National Survey on drug use, 19.5 million Americans ages 12 and older were current illicit drug users. 1 in every 13 adults is an alcoholic. The functionalist view is that society has norms and guidelines on alcohol and drug use. Social norms identify the appropriate use of drugs and alcohol. Prescription drugs are very functional in society because they can alleviate pain, reduce fever, and can curb infections. Even alcohol is accepted in moderation and can be consumed with meals and or celebrations. Sometimes there even health benefits, such as red wine being good for the heart. Society provides norms regarding the excessive use of drugs. Drug abuse can also occur when society is unable to provide guidelines for our behavior. Under certain situations that can be very stressful, people consume more alcohol and drugs. If people lack norms to control their behavior they are likely to pursue self-destructive behaviors like alcohol and drug abuse. Drug abuse is one of the biggest issues in social problems. Many of the people who take drugs face a lot of problems. There are many similarities and differences between the functionalist view and conflict view pertaining to drug abuse theory. From a functionalist perspective, drug abuse affects almost everyone in our society, directly or indirectly. Seventy million adult Americans have used illegal drugs at some time in their lives. The out come from this shows that 450,000 Americans die from smoking each year. When some of the people abuse drugs, they get addicted to it and then they tend to abuse it more. Addiction is uncontrollable and lots of people face the terrible repercussions; for example, losing their job, family, friends, health and their wealth. Getting addicted to drugs gets worse because the  data shows that, â€Å"97% of drug addicts never see treatment (NIDA InfoFacts: Understanding Drug Abuse and Addiction, 2005.)† Research has revealed how drug abuse cause s both short-term and long-term changes in brain function. These long-term brain changes are visible to scientists who can see what is going on in the brain with new scanning techniques. These changes make it nearly impossible for someone addicted to drugs to stop using them on their own; they need to get treatment. On the conflict side, it shows that, â€Å"95 percent of untreated addicts die of their addiction (NIDA InfoFacts: Understanding Drug Abuse and Addiction, 2005.)† There is a separation of classes and some of the people in society think that making people quit using drugs is their own business; they don’t have any concern for it. Some of the healthcare programs that have developed for the people who want to quit drugs show that, â€Å"for every dollar spent on addiction treatment, seven dollars are saved in costs to society in healthcare and criminal activity (NIDA InfoFacts: Understanding Drug Abuse and Addiction, 2005.)† Institutions have also been created to help people who want to quit. The National Institution of Drug Abuse (NIDA) stressed that researchers have shown that there are no effective treatments that can help people stop their addiction and prevent them from using it again. Basically, the conflict perspective views drug abuse as a problem of the classes, distinctly separated due to economic standing. There are many roles that are played in the functionalist prospective, which has lead to some of the results on the conflict side of drug abuse. For example, the government plays a big role in why their country’s population is in high or low percentage of using drug. Some countries like the United States strictly control the use of drugs by restricting access more and giving strict punishment, unlike Afghanistan, Columbia or some of the other countries. Most likely the government in these countries does not work hard on this issue because they are making profit off it or some of the big politicians are involved in it. In Afghanistan the government said that â€Å"no matter what we try to do to stop it, but it cannot be cured because drugs grow in almost 99% of the Afghanistan.† Countries like these can only try to lower drug production and abuse to a certain point, but not as low as the United States has reduces the trafficking and use of drugs. Parents play the  most important role of all. In some ways, they are responsible for why their child is on drugs, or they make it clear that drug use is unacceptable and harmful. For example, some of the parents do not care about their children and always have a negative response toward their children. This becomes stressful for the children and they start abusing drugs, thinking that it relives them but instead it makes the problems worse. They start abusing more drugs and end up in a very deep problem. On the other hand, some do mot even bother to take the drugs because their parents make it clear to them that drug use is never all right. In a recent study it shows that drug use is high among people who live in high degree of structural disadvantage, people who are less educated, low income, widespread poverty, high unemployment, high population density, low stability, and large African American population, which is why for some of the people using drugs is not a bad choice to th em but it is almost like their medicine to remedy their social status. Some of the people think that drinking alcohol is not taking a drug. It can be a drug if some is addicted to it. Data shows that, â€Å"fifty percent of the traffic deaths are alcohol related.† Teenagers have the highest percentage of drinking age in the USA because teenagers tend to drink more than the people who are over the age of thirty. This is all because teenagers are more aggressive, more imitating, more macho, and have some parents or close friends who are willing to buy alcohol for them. Many teenagers believe that alcohol and drug use is safe and are unaware of the consequences to excessive use. The average 18 years old has seen 100,000 television commercials encouraging them him of her to drink. According to the NIDA, that is why 90% of high school seniors have tried alcohol, 53% gets drunk at least once a month, 43% smoke marijuana, and about one third are smoking cigarettes. From the conflict perspective, a teenager who loses everything early in life or never had much to begin with, tends to drink or abuse more alcohol simply because they just think that it is helping them to forget everything. That leads to more problems and these children end up committing crimes and possibly could end up in jail. According to the conflict theory, people outside of this social class and situation are unwilling to help integrate these individuals back into society. Some people don’t realize  that just because of their addiction, it can take them to the point where no one can help them. Today there are about 190 million drug users all around the world, all of whom need help battling their addiction. The way to help them, however, varies between the conflict and functionalist perspectives. In conclusion, drug abuse presents a prevalent issue in today’s society. The conflict theory of sociology states that society functions so that each individual participant and its group struggles to maximize their benefits, which inevitably contributes to social change (such as changes in politics and revolutions.) This theory attempts to refute the functionalist perspective of social problems, which considers that societies function so that each individual and group plays a specific role, like organs in the body. A conflict theorist would suggest solving the problem of drug abuse by accommodating the needs of people in the classes suffering from drug use and educating them on the effects of drugs. The functionalist theorist, on the other hand, would suggest becoming more actively involved by reforming institutions as a whole and helping to redefine the abusers’ roles in society. Drug abuse is a very prevalent problem in the United States today and sociological theories provide for many different solutions.

Faraday’s Law Essay

The Faraday is the electrical charge contained in a mole of electrons. In this experimented 2 values are determined. One by measuring the amount of charge needed to reduce H+ ions to h2 gas, and the other is as Cu atoms are oxidized to Cu2+ ions. The chemical formula applied during this lab was Cu + 2H+-> Cu+2 + H2. Procedure Cleaned a copper plate in 2M HNO3, weighed it and recorded data. Mixed 100ml distilled water with 50ml of 3M sulfuric acid in a 200ml beaker. Put buret upside down into beaker and placed cathode up inside buret. Connected side aspirator to water aspirator. Set voltage regulator to zero turned power on; voltage was put to 190 amps and started recording the time. Regulated dial to keep current constant until 25ml of hydrogen had filled the buret. Data Calculations 1. Average current during electrolysis = 190 amps 2. Elapsed time in electrolysis (seconds) = 1080 seconds 3. Coulombs transferred in electrolysis = . 1900 x 1080 = 205. 2 coulombs 4. Mass loss of copper anode = 6. 6061g – 6. 5427g = . 0634g 5. Moles of Cu lost = . 0634/63. 54= 9. 98 x 10^-4 moles 6. Moles of e- released by Cu oxidation = 2 x 9. 98 x 10^-4 = . 00200 moles 7. Value of faraday for Cu oxidation = 205. 2/. 00200 = 1. 03 x 10^ -5 coulombs/moles 8. Mercury equivalent of water column = (1. 00g/mol)(337mm)=(H hg) = 24. 8 mm hg 9. Partial pressure of water vapor = 21. 068 (mm Hg) 10. partial pressure of hydrogen gas produced = 762. 5 = 24. 8 + 21. 068 + P h2 P h2 = 716. 6(mm Hg) 11. Moles of H2 formed = (. 943)(25. 3) = N(82. 05)(296) N=9. 8 x 10^-4 moles 12. Moles of e- use top reduce H+ = 2 x 9. 8 x 10^ – 4 = . 00196 moles 13. Value of Faraday of H+ reduction =205. 2/. 00196 = 1. 04 x 10 ^5 (coulombs/moles) Discussion 1. 04 x 10^5 coulombs was the calculated value for electrical charge contained in a mole of electrons. The equation applied for this experiment was Cu + 2H+ -> Cu+2 + H2. The experimental value calculated was 104,000, compared to the accepted value which is 96,500 coulombs/moles; the values are close in range. The percent error was 7. 77%, some possible reasons for error could producing too much or too little h2 in the buret. Another possible error could be not enough Cu+.

Vibration Measurement Instruments

VIBRATION MEASUREMENT In some practical situations, it might be difficult to develop a mathematical model of the system and predict its vibration characteristics through an analytical study. In such cases, we can use experimental methods to measure the vibration response of the system to a known input. This helps in identifying the system in terms of its mass, stiffness, and damping. In practice the measurement of vibration becomes necessary for the following reasons: 1.The increasing demands of higher productivity lead to higher operating speeds of machinery and efficient use of materials through lightweight structures. These trends make the occurrence of resonant conditions more frequent during the operation of machinery and reduce the reliability of the system. Hence the periodic measurement of vibration of machinery and structures becomes essential to ensure adequate safety margins. Any observed shift in the natural frequencies or other vibration characteristics will indicate eit her a failure or a need for maintenance of the machine. 2.The measurement of the natural frequencies of a structure or machine is useful in selecting the operational speeds of nearby machinery to avoid resonant conditions. 3. The theoretically vibration characteristics of a machine or structure may be different from the actual values due to the assumptions made in the analysis. 4. The measurement of frequencies of vibration and the forces developed is necessary in the design and operation of active vibration-isolation systems. 5. In many applications, the survivability of a structure or machine in a specified vibration environment is to be determined.If the structure or machine can perform the expected task even after completion of testing under the specified vibration environment, it is expected to survive the specified conditions. 6. Continuous systems are often approximated as multi-degree-of-freedom systems for simplicity. If the measured natural frequencies and mode shapes of a continuous system are comparable to the computed natural frequencies and mode shapes of the multi-degree of- freedom model, then the approximation will be proved to be a valid one. . The measurement of input and the resulting output vibration of a system help in identifying the system in terms of its mass, stiffness, and damping. 8. The information about ground vibrations due to earthquakes, fluctuating wind velocities on structures, random variation of ocean waves, and road surface roughness are important in the design of structures, machines, oil platforms, and vehicle suspension systems.In general, a transducer is a device that transforms changes in mechanical quantities (such as displacement, velocity, acceleration, or force) into changes in electrical quantities (such as voltage or current). Since the output signal (voltage or current) of a transducer is too small to be recorded directly, a signal conversion instrument is used to amplify the signal to the required value.The ou tput from the signal conversion instrument can be presented on a display unit for visual inspection, or recorded by a recording unit, or stored in a computer for later use. The data can then be analyzed to determine the desired vibration characteristics of the machine or structure. Depending on the quantity measured, a vibration measuring instrument is called a vibrometer, a velocity meter, an accelerometer, a phase meter, or a frequency meter.

Vision and Goals as a leader

The difference between a vision and a goal, one is abstract and one is concrete. Visions are essentially abstract, while setting a goal is more tangible. For an example of a vision, one would say they would like to plant a large garden that will produce a vast harvest In the spring; It will contain green beans, tomatoes and corn. This expresses an abstract desire for an outcome.Alternatively, a goal would sound like this, this springtime a large garden will be planted and time will be set aside to spend 5 hours a week hoeing the garden so the weeds will not interrupt the growth f the vegetables. This Is a substantial goal, meaning It Is a tangible and reachable, something you physically work towards. The subject of motivation can vary. In reality you will need to set the tone for the audience, in other words, different people will perceive different issues, and will be motivated by different things.Make sure you talk with your people regularly on a one-to-one basis to find out what m atters to them. Herbage's theory Is largely responsible for the practice of allowing people greater responsibility for planning and controlling their work. As a means of increasing motivation and satisfaction. The importance of visions is beyond dreams, It Is a statement of what or how you like things to be. Visions have a larger purpose and they share the core values that we hold at the center of our character. These core values are expressed to pave the road in the direction you want to see transpire.If a vision has been effectively communicated with precise and detailed direction and reason, others can see your mental picture to help you attain it and gain their commitment to it. ‘The only way to lead people Into the future is to connect with them deeply in the present. The only visions that take hold are shared visions-and you will create them only when you listen very, very closely to others, appreciate their hopes, and attend to their needs. † Souses, J. M. And Pos ter, 8. Z. To lead, create a shared vision. Harvard Business Publishing January 2009.This Is another important aspect of people seeing your vision is gaining their trust first. The significance of your vision and the excitement you display will help your team know where they are headed. This leads them see and become enthusiastic about the large depiction of your Image and gives them drive for a positive outcome. Nothing was ever created without vision. The importance of goals gives something to work towards to measure both personal and professional success.Without goals it is hard to believe in ourselves. Goals drive you forward, tells you what you truly want. Helps you achieve your desires by putting a large destination In smaller stepping stones to make it wealth a graspable reach. â€Å"Our goals can only be reached through a vehicle of a plan, in which we must fervently believe, and upon which we must vigorously act. There is no other route to success. â€Å"- Pablo Picasso. Obtaining goals within a group who trust their leadership, are far more willing to share in and work towards reaching goals.Contribute all energies in same direction with the same outcome to have substantial results. When goals are agreed upon within a group the success will be immeasurable. The article setting. The first step talks about developing a vision. It is important to know where you are going as an organization. A leader must develop a vision with a positive attitude and be ready to present it with energy. They must also be effective in communicating that vision to their employees, who in turn will work together to achieve that vision. The second step talks about the importance of goal setting.

Legal Underpinnings of Business Law Research Paper - 1
