Using a pendulum Essay Example for Free

Using a pendulum Essay To find the gravity by finding the period of the oscillations of a pendulum and plotting a graph. Hypothesis and Prediction: the gravity from the graph is going to equal the gravity from the formula. Variables: The independent variable is the length of the string The Dependent variable is the period of one oscillation Controlled variables are: mass of the pendulum Equipment: -Brass Ball -string -boss and clamp -stopwatch -2 metal blocks -Meter Ruler -Micrometer -The diameter of the brass ball was measured using a micrometer. Then the value was divided by 2 to give the radius.-the length of the string was measured -two metal block were clamped with the string in between, the string was tied to the bob -the bob was pulled to the side and released -the time was started when the bob passed the reference line. -a full oscillation is when the bob passes the reference line forth back and forth again. the length of the string is increased or decreased in a regular pattern the time was monitored by reading through the stopwatch. -the same brass ball was used over the experiment to keep the mass constant. the length was varied 10 times with a 10 cm difference. -4 readings were taken for each 10 cm -the time was taken for 20 oscillations. And then divided by 20 to give one oscillation. Data Collection: Table number Length of String / M i 0. 05 Number of oscillations Time Taken/s i 0. 5 Period/s i The table contains the length of the string in meters, the number of oscillations, the time per 20 oscillations and the period of one oscillation. As the length of the string deceases , the time for 1 oscillation decreases. So the length of the string is directly proportional to the period. Data Processing and presentation: Example in working out average period when the string is 1. 01 The graph is plotted with Average period squared against length of string. Y=3. 9244x-0. 0087 3. 9244=gradient. 3. 9244= (4(pi)^2)/g g = (4(pi)^2)/3. 9244 g=10. 060 from the graph. The average gravity from the formula= 100. 614/10= 10. 614 Conclusion: the results where very close to the prediction but they werent the same as the graph is a scatter diagram.-the result from the graph is more accurate as the graph cancels inaccurate measurements. Evaluation: -the method had weaknesses. -the angle of the pendulum to the reference line isnt the same in each reading which might cause a slight error. -the Air conditional may effect the pendulum; it may change its speed or change its direction. it is difficult to stop the stopwatch and start it in the reference line exactly which might induce error sometimes the ball tends to move in a circular motion and the experiment will have to be repeated.

sting of prejudice Essay -- essays research papers

Sting of Prejudice   Ã‚  Ã‚  Ã‚  Ã‚  In the novel To Kill a Mockingbird by Harper Lee there are many characters whose lives and thoughts about one another are distorted by prejudice and stereotyping. Three of the many characters whose lives were affected by prejudice are Bob Ewell, Tom Robinson and Dolfus Raymond. Bob Ewell’s mind is distorted in his view of other races. Tom Robinson is a victim of prejudice and is treated unfairly because of the color of his skin. The third character Dolfus Raymond is not accepted by the community because he is married to a black woman. These are three very different men whom by choice or circumstance are forever affected by the hatred associated with prejudice and stereotyping.   Ã‚  Ã‚  Ã‚  Ã‚  Bob Ewell is a man who is consumed by hatred, he is very poor and thinks very little of the black people in the community. Bob believes â€Å"that all Negroes lie, that all Negroes are basically immoral beings† (17). Prejudice in Maycomb is both racial and socio-economic. â€Å"The Cunninghams don’t like the Ewells† (226) because they consider them lower class. The â€Å"Ewells hate and despise the colored folks.† (226) The trial has given Bob Ewell the opportunity to not only persecute a black man but to feel in a very public way that he is superior and more believable to the jury because of his race.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  &nb...

Providing Free Wi-Fi to New York City

Providing Free Wi-Fi to New York City Defining the Solution: New York City is a city with a large population of people, lots of skyscraping buildings, numerous businesses, and a lack of available free WI-FI service. Today we will be working on developing a way to provide free WI-FI to all of New York City. First we have to look at the reasons, resources needed, and problems which will be on the road to providing such service to New York City. To define the problem a little in depth, we need to find out the necessities needed. 1.There needs to be a study conducted to figure out how a system can be placed in a city that is so rich in life, but cluttered with buildings and minimal available space for equipment installation. 2. The city needs to campaign a project, letting the people know what they are trying to do to bring such service to them. 3. Bring in network companies to provide the service. 4. Chart a project cost budget: i. e. -material cost, man power, and location cost. 5. Sur vey areas where service will be needed most. 6. Survey and gather information from the population on what service provider they use and service plans are used most.This will ensure that there are no network conflicts when the free WI-FI project is completed. 7. Schedule meeting with companies and experts in these technical areas to gather information. This will be information that can be charted or graphed. 8. Analyze all information, graphs, and charts that they have, to see problem areas and solutions to other problem areas. I am expecting that there will be many roadblocks to the road success. There will be many obstacles that will have to be problem and we will overcome these problems.But to develop a way to make WI-FI available to all of New York City will be tough project. It will be a tough project, however with great organization it can be a successful project. I believe with reliable and professional teamwork, it will be available in the future. Generating a Solution: Defin ing the problem for developing a solution to provide free WI-FI for all of New York City has been addressed. We have categorized where the problems lay and discussed what is needed to show the problems that exist. Now that the problems are defined, solutions need to be generated to piece together he problems. In order to generate a solution, a team comprised of technology professionals, state officials, city officials, private and non-profit developer organizations, the voice of the people, and a list of detail equipment needed and the cost of the equipment will need to be brought together as one. First is to assemble a group of broadband and wireless experts, so we can gather possible answers to the defined problem. After getting a starting point, data needs to be portrayed on charts, reports, and diagrams. This information can then be brought to the attention of city and state officials.The voice of the people can be a key to what is being used and what is needed to suit their nee ds for wireless connection. So surveys need to be sent out, public hearing need to be set up, and gather information from wireless companies to see what is being used today by the people. When setting up a public hearing, a panel of expert will be needed to answer the question that the people may have. Also to seek answers the experts will have for the people so they can configure the amount of technology is needed to make the project possible.The roles of the city government and the private and non-profit developers can be a major factor on how and where to start the wireless project. We would need the approval from these groups to have a starting point. Also we would see what resources the city already have and what is needed to included in a report for financial purposes. The financial report is essential to show what is already available for use in the project and what resource is needed plus the cost for the needed equipment. Then a starting location(s) will be needed to begin the project.Possible locations (ie: city parks) for wireless hotspots can be a good starting expansion point. To generate a solution we need: 1. Broadband and Wireless Experts 2. Approval from the City Government 3. Private and Non-Profit Development Organizations 4. State Agency Resources 5. The voice of the people 6. Locations 7. Financial Resources 8. Financial Report of Resource and Equipment Cost The next step is to gather all the possible solution information and analyze the data. Deciding a Course of Action:In generating a solution, we have learned that there are a variety of resources that have to be looked at in order for a solution to be found. We found that a team of technical professionals (ie: wireless carrier companies, IT organizations, and city electrical development department) is needed for wireless development. The voice of the people; to see what wireless carriers are being used, to survey where they use it more, and where they would like to use the wireless serv ice at. State and city officials are needed to help implement the project by vote of approval. Private and non-profit organizations are needed to fund this project.Last is to purchase the equipment for wireless capability. Deciding a course of action for the solution means that we need to take a look at what is at the top of the priority list. At the top of the priority list would be to speak with technical professionals, to see if it is possible to supply the wireless without any possible signal problems to disrupt the use of wireless service. Through this we can generate a list of resources that are needed. After speaking with various technical professionals, we see that location is also a factor when it comes to wireless service.After conducting a grid survey, a decision is made to use local and state parks as areas for project development. Through this detailed reports and charts are made for state and city officials and private and non-profit development organizations to view t he results. Next a survey is sent out to the people to see if the technical professionals and grid survey team studies are correct. As the surveys are collected and read, it is determined that the studies are correct and the parks will be accurate locations for project development. With the completion of the surveys from the people, the information is then added to the project report.In addition to the report, survey charts are created to show the mapped locations for possible WIFI development service. Plus, bar and line charts will show why these locations were chosen, as well as additional charts to show the results of the surveys sent out to the people. Third course of action is to petition to speak with the state and city officials and present the report that can provide the Free WIFI access to the city and its people. By doing this, we can seek approval to start the development and to seek the both private and non-profit development organizations.These development organizations will help finance the development project and make it a reality. After attending numerous meetings with state and city officials, technical professionals, development organizations, and getting the approvals that is needed to start development. The last course of action is to purchase the equipment that will provide the WIFI service. The WIFI project will only give access in state and local park areas, this type of WIFI access service will be considered Hotspots or Hotzones for the free WIFI access. Implementing the Solution:Deciding the course of action has shown what the top priorities are and has helped develop the steps to getting started. Next is to implement the solution to make it a reality. A proposal was submitted to address state officials and local city council about the proposed project development. In turn we received a response from these governing offices that we will be heard on the subject of providing the Wi-Fi service to the city. Before we attend the scheduled d ay, we must overlook the project report and charts, to see that all the information is correct and formal.By going back and double checking everything will help us be more confident when we sell the idea, plus we will be well prepared to answer any questions that may be addressed. After looking over all the charts and the project report, it was noted that a project schedule timeline and a budget chart was not created. So we decided to send out a research team to determine how much time will be needed to complete the project and at what cost. First a Gantt chart is created to show the activity process, along with the months and year that each activity will be taking place.We can also have a visual schedule to see what task is in development and at when the deadline should be. Next is to create a budget list (chart). The chart will show the cost for employment of personnel (salaries& contracted personnel), equipment use (purchased or rented), Travel expenses (if any), technology suppl ies and equipment, and last is to show the projects overhead cost. A budget chart is vital when speaking to government officials and organizations funding the project. The project budget cost can be a factor if we get the funding and/or approval.Now that project report is completed and all the required information is within the report, we are now ready to present it to the government officials. As the day comes and all the important variables are presented to the council of officials, we wait till they discuss the development project. The development project finally receives the approval, which moves the project to the next part of the implement stage. Checking the Gantt chart, we see that we need to employ a development team. This team needs to consist of IT experts and professionals, project managers, and a team of hands on working professional.We also need to purchase all the necessary technological (laptops, desktops, software, and communication devices) and development equipmen t needed to start the project. Next we need to schedule several meeting with the major wireless carriers to introduce to project in development and to try to influence them to be the wireless provider company. In order to choose the right companies to contact, we will schedule a public meeting to speak with NYC residents. By doing this we can see who is the major providers that the public use.Through several public meetings, we find out that AT&T and Verizon is the two providers that are used to most. So we call and schedule a meeting with the board of directors from both companies. Plus we have to schedule the proper flights to get to the corporate offices for these companies. After several physical and telephone conference meetings, both corporate providers agree to be involved in the development and would immediately put together a team to assist our development team in installing the necessary networks that we need. Through this, a change is made on the Gantt chart to include th ese companies and their team.Plus any cost will also include into the budget chart. With all the project resources that is needed for this project have been brought together, the deployment stage of the project needs to be started. Several meetings are set up to introduce all the executives, project management, government officials, and funding organizations. Construction crews and technical personnel need to be hired. Equipment needs to be ordered and purchased before the start of the project. Checking the development location charts, it has been determined that wireless systems need to be placed on high level areas.So checking city maps and blueprints, we choose city skyscrapers that have the high altitude we need. Checking with the buildings management and owners, we started to implement the wireless system construction. As the project goes through the various stages of the development; we consistently monitor the Gantt chart to make sure that the project is on schedule, continue to check for any potential paradigm shifts that can cause a delay, make sure that there is coordination of all tasks and personnel, and evaluate each completed task along the way.Experimental test are conducted throughout the development stages, to make sure that all equipment if properly functioning and compatible with our needs. To avoid any possible setbacks, contingency plans are implemented and alternate plans are made. Any changes to the project must always be reported and charted to keep all departments updated and informed. As we can see, this development project has many variables while implementing any solutions. We have to keep on track during the process and evaluate all solutions as they presented.Evaluate the Solution With the implementation of the project development, we need to consistently evaluate the solution. By doing this we will see: if the solution is logical and solves the real problem, if the solution is (economically, environmentally, politically, and ethn ically) responsible and safe, does it meet all the criteria and constraints, is it blunder-free, have we argued the positive and negative sides of the project, and check the procedure and logic of the arguments.We also have to create an ethics checklist to see if it is legal (will it violate civil law or company policy? ), will it be a win/win situation, will it be fair to all concerned in both the short term and long term, and will I be proud during the development stages and/or conclusion. We also have to remind ourselves about â€Å"purpose†. What is the purpose of why we started this project and what is the purpose of seeing this thru till the end? I see this as a motivation tool to make sure that we maintain the excitement of the project.While we are evaluating the solution, we need to implement a contingency plan for each stage of the development process. This will ensure that there is a back-up plan if we experience a paradigm shift or the project is at a development d own fall. After conducting a thorough evaluation of the solution and development process, we come to the conclusion of the project. By taking the steps to seeing the project through from defining the solution to evaluating the

Child Abuse and Neglect Essay

â€Å"Every year 3.3 million reports of child abuse are made in the United States involving nearly 6 million children (a report can include multiple children). The United States has the worst record in the industrialized nation – losing five children every day due to abuse-related deaths.† stated by Sara O’Meara. That’s a very depressing fact, especially because the United States has the worst record. That fact is solely based on the cases that were reported. Can you imagine all the ones that weren’t? There is so much information on this topic, but it seems that nothing is changing to stop child abuse and neglect. This is a huge problem even though there are many strategies to improve this issue it’s still not helping enough. Child abuse is a horrifying subject to bring talk about, but it needs to be approached. Child abuse and neglect has been going on for centuries. It came to be noticed in the early 1870’s by a young girl, Mary Ellen Wilson, who was being whipped by her foster mother. After her case went before a judge citizens formed the New York Society for the Prevention of Cruelty to Children. A child abuse came again in 1962 when people read an article in Journal of the American Medical Association. This article described the symptoms of child abuse and it stated that child abuse could be medically diagnosable. â€Å"Within ten years, every state had statutes known as â€Å"mandatory reporting† law. Mandatory reporting laws require certain professionals – doctors and teachers for example—to report to police suspected child abuse situations. A 1974 federal law further bolstered efforts to eliminate child abuse by funding programs to help individuals identify and report child abuse and to provide shelter and other protective services to victims.† Stated on the Department of Children and Families website child abuse is defined as â€Å"a non-accidental injury to a child which, regardless of motive, is inflicted or allowed to be inflicted by the person responsible for the child’s care, includes any injury which is at variance with the history given, maltreatment such as, but not limited to, malnutrition, sexual molestation, deprivation of necessities, emotional maltreatment or cruel punishment.† Physical Abuse is the most noticeable on a child because you can see it. Some examples are broken bones, fractures, bruises, cuts, burns, and more. Not all children will admit they’re being abused. Ways to tell that they are could be that the injuries are frequent, the child is afraid of touch, or seems to be afraid to go home. It’s much more difficult to tell is a child is being sexually abused or emotionally abused, but being abused in these aspects are just as heartbreaking and appalling. Children are being raped, not being fed properly, talked down too, being rejected of love, being left alone at a young age, and other awful things. It’s not only abuse that can happen to a child, but there is also neglect. There can be physical, educational, and emotional neglect that can occur in a child’s life. Some examples of physical neglect are when parents or guardians don’t get proper health care for their children or don’t watch their children with proper supervision. These factors can really harm a child as much as people don’t want to believe it. Educational neglect is when the child isn’t enrolled in school or if a parent or guardian doesn’t want to put their child in a special needs program even if they need to be in one. It’s understandable that some people don’t want to put their children in a special needs program because they’re embarrassed or think they can fix the child on their own. Well listen up parents, it’s known as neglect if the child isn’t helped in the proper way. Emotional neglect is extremely cruel because it’s when a parent doesn’t give the love a child needs to grow or allows a child to do drugs in the house, or drink underage. There are many examples I have left out in all three neglectful ways of being a parent or guardian because to be honest there is way too many to list. An extensive body of research provides promising and best practices on what works to improve child safety and well-being outcomes and reduce the occurrence of child abuse and neglect. These efforts are essential as child abuse and neglect have pervasive and long-lasting effects on children, their families, and the society. Department of Children and Families provide safety and services. They do professional investigations and appropriate evaluations on physical abuse, emotional neglect, sexual abuse, medical, or educational neglect. Please make sure to report child abuse or neglect as soon as possible because the life of this child is very important and your phone call could make a huge difference. After your report is complete, DCF begins their investigation within two hours of your call if there is a serious risk of physical harm to a child, and within three days for all other reports. Their number is 1-800-842-2288. Another good resource for providing help is American Academy of Pediatrics (AAP). â€Å"The AAP has a research program that helps to improve the methods of health care to children. It’s a professional membership organization of 60,000 primary care pediatricians, pediatric medical sub-specialists and pediatric surgical specialists. The mission of the American Academy of Pediatrics is to attain optimal physical, mental, and social health and well-being for all infants, children, adolescents and young adults. To accomplish this, AAP shall support the professional needs of its members. It has 1,800 pediatricians in the research program and it is the longest-running research programs in the U.S. AAP is looking out for the health care of all aged children and is a great resource to get children the health care they need.† There is also ways a person can help the abused or neglected child themselves before calling for professional help. It’s important to look into strategies on how to help an abused or neglected child and to also get the abuser the help that he/she needs to stop this cruelty. When you notice a child has been being abused or neglected a person can approach the child and ask them to explain their story. When the child tells their story try not to look horrified or shocked and don’t talk down about the abuser. If the child is not ready to tell their story don’t push the child to do so because it may drive them away. A child is not the only one who needs help when being abused, the abuser does also. The major reasons for physical and psychological mistreatment of children within the family often are parental feelings of isolation, stress, and frustration. Parents need to learn to cope with their feelings. Support groups through local community organizations often are helpful first steps to diminish some of the isolation or frustrations parents are feeling. People truly need to keep their eyes wide open and stop being oblivious to child abuse and neglect. As horrific it may seem the statistics show that 6 million children a year are being affected by child abuse and neglect. Please remember it’s not always easy to spot because it’s not just physical abuse that can happen to a child it’s so much more. Every type of abuse or neglect hurts whether it’s physical or not. Get in contact with Department of Children and Families or another child abuse and neglect group that you can contact if you suspect child abuse or neglect, it’s very important. Child abuse and neglect has been going on for centuries! Let’s try and stop it for happening to these innocent children!

Groupthink Concept and High

Groupthink Concept and High Groupthink Concept Groupthink refers to a psychological phenomenon happening within a cluster of persons under which the aspiration for conventionality within this cluster results in a biased outcome in the decisions made.Advertising We will write a custom critical writing sample on Groupthink Concept and High-Quality Decision Making specifically for you for only $16.05 $11/page Learn More The main underlying assumption towards belonging to this cluster is the need to minimize conflict through blind conformity. Thus, an individual caught up in a groupthink phenomenon is blindly loyal to a set of thoughts or actions for fear of being controversial as a result of exercising independent thinking. The often dysfunctional dynamics within such a group generates what is commonly referred to as an â€Å"illusion of invulnerability†1. Actually, the groupthink psychology makes persons belonging to this group to belief in universality of their decisions as right without accommodating the opponents’ abilities, which are often underrated. In the worst case, groupthink orientation in the decision making process may generate actions that are dehumanizing those perceived as belonging to the opponent quarter. High-Quality Decision Making The process of high-quality decision making is dependent on heuristic since it provides assumptions, integration of options, and rational control. Decision environment often experience dynamics and swings which create short and long term effect on chances of survival for two alternatives to solve a problem. When faced with a decision problem that requires critical assessments, high-quality decision making process resorts to analytical tools that ensure competitive positioning advantage and rationality. Each option is assigned to a quadrant with predetermined response strategies and ‘follow-ups’ upon each decision made2. Differences between Groupthink and High-Quality Decision Making High-qual ity decision making functions on the presence of rationality and verifiable facts, irrespective of the position or situation that the decision making agents are in. Unlike groupthink decision making process, high-quality decision making incorporates a series of perspectives through which the final decision is identified via a qualitative analysis.Advertising Looking for critical writing on government? Let's see if we can help you! Get your first paper with 15% OFF Learn More Therefore, high-quality decision making relies heavily on the pillar of alternatives through research and knowledge of the situation or problem. On the other hand, groupthink (‘ingroup’) decision making process only accommodate the views of a cluster of individuals who belong to similar orientation and cannot exercise independent thinking. Decision making through groupthink is very biased since the underlying determinants of the decision matrix is loyalty and â€Å"illusion of vulnerability†3. Since high-quality decision making process operates on the periphery of rationality parameter, the final verdict can be described as reliable and accommodate variant views. Given that different aspects of decision making such as assumptions, integration of options, and rational control are integrated, most of visible or invisible biases are dampened as the effects of social presence elevate the decision science. Unfortunately, the groupthink phenomenon has structural faults which prevent the benefits of reliability and social effects since it is characterized by a context of provocative situation. Besides, groupthink decision process is characterized by internal or external pressures for a consensus which may generate accord-seeking propensities. Unlike high-quality decision, groupthink creates a false illusion which is inherently dysfunctional4. An example of groupthink is the decision biases that led to an attack on Pearl Harbor by the Japanese in the yea r 1941. Persons entrusted with the responsibility of rational decision making allowed shared rationalizations and illusions to shadow their judgment on the need for precautions. However, the attack could have been avoided had the decision makers embraced the components of high-quality decision making. Bibliography Fiske, Susan, and Shelley Taylor.

Fortune 500 Companies Research Paper Example | Topics and Well Written Essays - 750 words

Fortune 500 Companies - Research Paper Example Approximately two-thirds of the Fortune 500 companies are currently involved in offering partnership benefits. In order to understand this aspect better, it is important that concern is drawn as to what entails domestic partnership benefits (Rosenbaum, 1967). Ideally, domestic partnership benefits are those that an employer decides to give to an employee’s unmarried partner, regardless of the gender. Despite the numerous companies that are currently involved in offering domestic partnership benefits, this paper will only analyze Wal-Mart stores and Mayo Clinic. Offering of partner benefits, follows the passing of ordinance in 1996, with an essential requirement that companies involved in business with the city are mandated to offer equal benefits to their employees’ partners without any attribute towards gender orientation. The benefits offered by these companies are mainly in healthcare. For an employee’s partner to access the partner benefits, there are certain requirements that such an employee partner must acquire. Different companies have different requirements on who is eligible to access the benefits. For Wal-Mart stores, partners are only covered when they are legally married and never when legally separated (US News, 2013). Regardless of the gender of the partner, such an individual is only eligible for the benefits if the two are in a relationship in an equivalent of marriage for 12 months, and with an intention of sharing the particular household forever. It is also important that the partner to benefit from the offer must be 18 years old and above. Mayo Clinic currently has not set a particular deadline for which the partners in a relationship can start accessing the benefits (Berry and Seltman, 2008). However, in the case of same-sex partners, then the two have to marry in the case of Mayo Clinic, considering that same-sex marriages have been
