Exploring Reliability and Validity

Exploring Reliability and Validity Types of reliability and validity used in the â€Å"Values and Motives Manual† One type of testing reliability used in the article is the inters of valid scores shown by the correlation co-efficient between VMI affection and 16PF are ‘privateness’ with a coefficient of -0.41, social desirability/ impression management with a correlation coefficient of 0.4, and those with higher values (Values and Motives Questionnaire, n.d., p. 23, table 5). VMI and OPP constructs indicate two scores having a correlation coefficient of 0.7. It indicates that the scores are strongly related. As a result of strong correlation, the social desirable coefficient for the two constructs is 0.58, and a central responding correlate of 0.75. Correlation coefficients that are less than 0.5 (normal) are invalid. For VIM/OPP, the valid scores are altruism/ cynical-trusting (0.51), traditional/ detailed-flexible (-0.58), affiliation/ reserved-gregarious (0.73) among others (Values and Motives Q uestionnaire, n.d., p. 25, table 6). Sample size and nature of population The larger the sample size, the lower the standard error. A high value in the standard error reduces the validity of the test. It may indicate that the scores are different from those in the population. The samples have been selected from a population which tends to have a higher education index than the overall population in the country. The population is more sophisticated because it mainly consists of undergraduate and postgraduate students. The research outcome may be different if the sample if drawn from the country’s population (Values and Motives Questionnaire, n.d.). An opinion about the test The test is valid and reliable if it used to interpret values among college students. It includes both undergraduate and postgraduate students. However, it cannot be used to make conclusions about the country’s population.Advertising We will write a custom critical writing sample on Exploring Reliability and Validity specifically for you for only $16.05 $11/page Learn More Kaplan, R., Saccuzzo, P.

Bring and Take

Bring and Take Bring and Take Bring and Take By Jacquelyn Landis Writers tend to get confused about when to use bring and take. Many think that the two words can be used interchangeably, but they do have two distinctly different uses. Which one you use depends entirely on your perspective for the action. Bring indicates action coming toward the speaker; take means action taken away from the speaker. So from your perspective, your kids will bring their homework to you to check, and then they’ll take it to school tomorrow. From your kids’ perspective, they’ll take their homework to you and then bring it with them when they go to school tomorrow. The trick is to think about your location. Something coming your way is brought to you. Something going away is taken from you. It can get confusing occasionally, and when it does you have to depend on the surrounding context to help you determine the point of reference. Check out these examples: Be sure to bring a jacket with you in case it gets cold. Be sure to take a jacket with you in case it gets cold. Both can be correct. In the former example, the meaning is to carry the jacket with you to where you are going. It’s likely that this would be something the person you’re joining would say to you. In the latter example, the meaning is to take it away from your starting point. It sounds a lot like something Mom would say as you’re running out of the house. To simplify the concept even more, think of it like this: you bring things here and take them there. It’s not an infallible method, but it works most of the time.

Complacent Employee, Sharon B. Buchbinder Case Study

Complacent Employee, Sharon B. Buchbinder - Case Study Example He feels beleaguered with all the busy schedule and work load and believes that his work is loved by all teachers and students. He works for long hours and stays at school till late hours to attend to all the needs and requirements of the students in the school. He is dedicated to his work assisting troubled kids and at times their families. His office is often filled with kids that need to be psychological assistance and are troubled from problem arising from either at school or home. This case involves Miller, who is satisfied with is work being fired by the administration because it aims to cut down on its cut backs and budgets. It is during one of this session that he receives an unexpected visitor. The unexpected visitor was his Boss miss Harriet who rarely visited. It was the first time for her to come to Miller’s office. When, he saw her miller immediately suspected that something was amiss. Her visits to the elementary school were always brief as she only greeted and a t times grinned to people and left the premises shortly after. However in this occasion she had something, to share with Miller and, he suspected that it was something serious. According to Miller his job entailed counseling troubled kids and ensuring that they did not end up in any stupid act. For instance, the kid he was tending to shortly before Harriet arrived was threatening to kill herself by taking several pills (Buchbinder, 380). Although, Miller was a hard worker and concentrated fully on his main task of counseling he was wrong on ignoring other prescriptions of his work. The job entitled him to write reports to administration to illustrate his contribution to the school. However, he ignored this thus leading to the administration to conclude that he was doing nothing. Although he explains to his boss that he is industrious, and works for lengthy hours he was wrong to ignore writing of reports which was significant to the administration. By ignoring his duties, and assumin g the reports could wait was wrong. Bob also assumed that the reports meant for the superiors were unnecessary (Buchbinder, 379). This was detrimental to his career because part of the consequence would be him losing his job. Without those reports, this was because his superiors could not know whether he was performing his duties but assume that he was sitting at his desk doing nothing. The administration way of assessing its employees is ineffective. This is because no one supervises Bob or requests for the reports. This indicates the weakness of the school administration. It does not have a personal touch with it employees thus leading to the situation such as Bob’s. It is only ethical that when someone makes a mistake mostly in the working place, they should be warned at least once before firing them. It came as a shock to Bob when the news of his lay off was broken to him as he was not aware. Everything was done in a short notice that did not even prepare him psychologica lly. Bad news, such as a person losing a job is not something that should be done in a hurried manner, for they might cause serious repercussions (Sims, 1). The administration should have at least notified its employees of the planned layoffs. This was unfair to the employees such as Bob who are left jobless without an arranged plan B. Using a short notice to fire puts Bob in a peculiar position as he believes he has devoted his life to labor for the school; thus he deserves a decent treatment despite his flaws. It is also disheartening to discover that the administration has already lined up a replacement for Bob even before he has left. The administration has already hired the services of a part-time psychologist from Melville middle School to take Bob’s position (Buchbinder, 380). However, it is true that Bob’

Managing for the future Essay Example | Topics and Well Written Essays - 5000 words

Managing for the future - Essay Example During the time of the eminent economist, concepts such as ethical decision making, corporate social responsibility (CSR) were at the budding stage, hence, most of the economists including Milton Friedman ignored the role of social responsibility for business. Over the last few decades, the importance of ethics has been increased among corporate world. Modern research scholars such as Jain (2009) and Tett (2009) criticised the immaturity in terms of ethical understanding among business leaders as the root cause behind the global crisis. The concepts like corporate social responsibility (CSR) is pretty much new for companies in emerging market and as a result, many of them are still struggling with implementation of a holistic CSR framework which can ensure social well being and environment sustainability. Visser (2010) and Velasquez (2000) argued that concept of corporate governance is generally misunderstood by business leaders because they believe that corporate governance is all a bout structure which is not correct. In such context, modern research scholars such as Waller and Conaway (2011) pointed out three important future challenges for organizations such as, 1-deploying CSR activities in comprehensive manner in most of its business verticals, 2-taking the strong leadership role by expanding business in cross cultural and country manner and 3- managing crisis in efficient manner in order to ensure smooth flow of operation. Issaksson and Jorgensen (2010) argued that companies need to work closely with their stakeholders in order to balance the environment sustainability activities and profit pooling activities. According to these research scholars, the profit-greedy mentality of organizations cannot help it to achieve sustainable growth because modern organization has to consider the effect of its operation in external environment. Du, Bhattacharya and Sen (2010) defined CSR as a commitment from corporate to ensure well being of social members and help the society to achieve inclusive growth. It is evident from the above mentioned definition that it is responsibility of companies to improve social life of people by using internal resources and good practices. Waddock (2008) even argued that companies can enhance their brand image by engaging in CSR activities which can help the company to fulfil ethical, social and environmental requirements. The researcher has selected Starbucks in order to understand how the above mentioned three factors such as CSR, globalization and crisis and catastrophe management can impact business environment of the company. After analyzing the business environment and its previous challenges for Starbucks, the study will predict future business path for the company. At first, the researcher will try to understand the business matrix of Starbucks. Starbucks-Business Matrix and Capabilities Starbucks Corporation was founded by Jerry Baldwin, Gordon Bowker and Zev Siegl during the year 1971 and the company is headquartered Seattle, Washington, U.S (Starbucks, 2012). Till date, Starbucks has established more than

Are Electric Cars the Future of Transportation?

Are Electric Cars the Future of Transportation? To boost the research and purchases of electric cars to reduce future pollution of the environment, manufacturers and consumers would benefit from subsidies and incentives from the government. This could provide a more economical and environmental friendly means of transportation in the future that would help in protecting the environment. There is the debate on the research and development of a more efficient electric car would produce more pollution by means of manufacturing. The long term gain in managing to produce an electric car that does short distance travel as well as long distance could mean less pollution as the technology advances to make on that is more efficient than today’s version of electric cars. As children from the 1960s to the 1980s, we watched The Jetson’s with the idea that one day the future would be very much like life living there. Flying cars, robot maids, instant full meals, and also traveling around with jet packs. Life seemingly made much easier with the use of technology. So far today, transportation has progressed in technology from horse drawn carriages to gasoline powered cars and now on to the way of electric cars. There has been an effort in trying to lower the effects of pollution from the technology of standard cars in the last few years. Cars have been manufactured for years, however, in the early years there was not a cause for concern with the environment. The main reason being the amount of cars on the road were not as many due to that many people could not afford one since it was considered a luxury. Over the years, cars became more affordable. Families were able to afford more than one car and soon became multi car families. With the addition of more cars being manufactured and running on the road, the emissions being produced have increased creating pollution that is causing many issues. With the current technology, manufacturers are attempting to find ways to make electric cars that are more affordable, reliable, and efficient. Once electric cars are more readily affordable, became able to travel long distances, and the installation of charging stations, the emissions would decrease and the environment would being to improve from the lack of pollution. There are a few advantages to electric cars. The first is dependency on fossil fuels by standard cars would be gone, which would reduce the costs of fuels if one purchased a hybrid of an electric and fuel cross type of car. If one purchased a fully electric car, then the fuel costs would be completely cut and thus saving money by having no fuel expenses. This would mean either a substantial decrease or complete cut in fuel costs with either type of car given the current rising costs in fuels. The other advantage over changing from a standard car to an electric one is that if there was a complete switch to an all-electric or a plug-in extended car, the nation would save 15 billion gallons of gasoline each year. (Pasadena Star-News, 2013). Thus reducing the costs for gasoline for both the nation as well as consumers. Maintenance is another issue with both standard and electric cars. There is a cost difference between the two. The advantage with electric cars are that a lot of mechanics observe that even though electric car engines still have moving parts, the maintenances is way easier, faster and cheaper (PR Newswire US, 2014). With an electric car, the rides should be quieter and smoother than a standard one. There’s a $7,500 federal tax credit for buyers of plug-in electric vehicles, and there are incentives for building charging stations and battery plants. (Fort Worth Star-Telegram, 2013) With federal and state tax credits, some models of electric cars are arguably competitive with standard mid-line economy cars. The cost of a Nissan Leaf, is listed for $30,000 to $31,000 at the Boulder Nissan dealership, will drop to $17,500 to $18,500 after federal and state credits. (The Denver Post, 2013) Tax credits, subsidies, fuel, maintenance, no emissions, and reliability are just to name a few more of the advantages to owning an electric car. The idea that being able to cut costs towards fuel purchases and maintenance is appealing when faced with the rising costs of both as well as the credits to lower the initial purchase cost. Battery, plug-in hybrids, hybrids, and hydrogen fuel-cell cars are the four types of electric cars currently in development. Battery electric cars have electric motors and battery packs with no other means of propulsion. The distances is usually about 100 miles. Plug-in hybrids act like an electric car from the first 15 to 50 miles, then can be switched over to a onboard internal-combustion engine that acts as a generator. Hybrids either use an electric motor as assists for the gas engine, or allow short bursts of electric-only driving. The hydrogen fuel-cell cars has a fuel cell that produces electricity from hydrogen which replaces the battery pack (Motavalli, 2012). While these are the current standards with these types of electric cars, the improvement in technology will change those over time. Environmental advantages with the electric car versus a standard one is that an electric car does not emit any emissions. A standard car emits pollutants from by the way they are powered. The way a standard car works is by combusting fuel, which in turn creates carbon dioxide that cannot be minimized through the use of emissions-control devices (Kliesch, 2011). A full electric car does not require any fuel, which in turn would not emit any emissions to create pollution. While there are many advantages to owning an electric car, there are disadvantages as well. One is the currently the way electricity is used to charge one is produced. Depending on the source of electricity generated will determine the amount of pollution. There are several different sources used in how electricity is generated. There are renewable sources, such as solar, wind and hydropower. Then there is the natural gas, coal-fired and nuclear plants. While the renewable sources would mean for the electric car to be manufactured by no pollution effects to the environment. The next in line for least amount of pollution is the natural gas plants, while coal-fired is the worst to emit high levels of carbon dioxide as well as particulate matter. Nuclear plants, while not a threat from global warming or smog-forming pollution standpoint, pose the dangerous threats of nuclear disasters and nuclear proliferation (Kliesch, 2011). Renewable sources are still being incorporated into the curr ent technology and life styles. While there is quite a few different types of pollution, a car produces 3 different types. The types produced from cars are categorized as – in-use, upstream and vehicle-manufacturing emissions. The definition of in-use is when a person is actually driving the car. While upstream emissions result from the production and transportation the fuel a car uses to where it is used. The third manufacturing-related emissions, accounts for about 10 to 20 percent of a vehicle’s lifetime greenhouse output (Kliesch, 2011). To be fair, that is only a portion of what contributes to pollution on a large scale. Those are what accounts for a standard car’s emissions. The electric car produces no in-use emissions, but they do have upstream emissions from where the electricity is produced in order to charge the battery. If one looks at the amount of pollution emitted by a standard car versus an electric one, it can be seen as to how much of a difference there is. A difference that is also affected by the location the car is driven in. If one lived in California and had an electric car, driving 12,000 miles in a year would emit about 1.6 tons of carbon dioxide. However, by contrast a hybrid would emit about 2.9 tons and a 25 mile per hour car would emit about 5.9 tons (Kliesch, 2011). Being that California has the most advantage with the cleaner of electricity produced, it would be a huge impact on reducing pollution by changing from a standard car to an electric one. The reason the government should be offering incentives and subsidies to the consumer as well as manufacturers are to help in reducing the dependency upon petroleum-based fuels. By investing into cleaner energies and cleaner cars, the impact of pollution caused by those would help the environment over a period of time. As the population that inhabits the Earth, this is the only planet able to sustain human life and needs to be protected for future generations to live here. In time there will be too much pollution that will cause many more health issues and possibly make the Earth unlivable in the future. With purchasing an electric car, one would have an immediate change in fuel costs. It would depend on the type of car purchased. If it were an all-electric car, then fuel costs would be eliminated. With a hybrid type, the amount of fuel purchases would possibly be cut up to half or perhaps more. To put it to numbers, drivers may ultimately compare fuel efficiency by how much it would cost to purchase fuel versus cost to charge with electricity. If gas costs $3 per gallon and typical mileage is 25 miles per gallon, it will take 4 gallons of gas to go 100 miles, at a total cost of $12. The per-mile cost is one hundredth of that, or 12 cents per mile. For the Prius, at 50 miles per gallon, fueling costs are half that: 6 cents per miles (PR, N, 2014). This is a considerable difference in cost per mile for standard car versus an electric car. As long as technology improves in different areas, then the advantages will outweigh the disadvantages on owning an electric car. The current means of manufacturing and ways to recharge an electric car to be improved to reduce the level of pollution side effects on the environment as well as lower the costs to purchase an electric car. The improvements with an electric car being able to travel further distances by improving the battery capacity and then implementing of charging stations much like gas stations. While those improvements are being made with electric cars, the technology for current production of electricity will be improved upon as well. This will reduce the pollution created from not only standard cars, but as well as the general usage by homes and businesses. This will bring forth protecting the population to being able to live in a healthier, better breathing environment much like in the days prior to the invention of cars. With the ground work in place for evolving the future of transportation to improve the environment, it is also going to be making an impact on the future of how electricity is made. While technology will change to improve the electric car, it will also change how electricity is produced. This will reduce the impact to the environment with the emissions produced from some forms of electricity production and standard cars. The placement of incentives and subsidies will enable consumers and manufacturers to purchase and develop a cheaper, environmental friendly electric car. The research into making an electric car travel further distances will also boost research into changing how electricity is used to recharge the battery. In time there will be charging stations very similar to today’s gas stations, allowing people to travel further instead of staying within a certain distance. The quiet and smooth ride of an electric car could change the comfort level versus the standard. Wit h the rising costs of fuel and maintenance for a standard car would decrease if each home were able to afford the initial purchase of an electric car. In time, electric cars will be manufactured for less and be similar in purchase cast a standard car, or perhaps even less. The future of the environment seems dependent on putting more effort into the research and manufacturing of a more economical and efficient electric car. References PR, N. (2014, March 7).

Developmental Psychology and Children Essay

1.1 An explanation of the legal status and principles of the relevant Early Years Framework and why the early years frameworks emphasise a personal and individual approach to learning development. The department of Education have issued a statutory Framework for Nursery settings, known as the Early Years Foundation Stage. The framework sets the legal requirements for the care of young children relating to Learning, Development and Welfare. The EYFS framework sets the UK standards for learning, development and care for children from birth to five. The curriculum is built around four principles: 1.A Unique Child 2.Positive Relationships 3.Enabling Environments 4.Learning and Development To give a basic understanding of the four principles, I will explain them below: A Unique Child You should focus on how children develop and recognise they are all different, but should be treated equally. Positive relationships and good communication are vital. Children need to learn about risks and safety, how to make good choices and how to stick to boundaries. Positive Relationships The theme is about children learning to manage their feelings and build relationships. You should respect all kinds of families and aim to develop a positive two-way relationship with parents. You will support, listen and work with the children to help them learn.Have a nominated key carer for each child to ensure they have the opportunity of building a close relationship and are well monitored during their time with you. Enabling Environments Plan and check on each child’s progress and make every attempt to involve parents and the local community. Ensure that inside and outside spaces of the nursery are safe, interesting and engaging. Learning and Development Focus on ensuring young children learn through play and exploration, with support for each individual. You should encourage children to develop imagination, to get actively involved in learning and to make decisions. Make every attempt to develop children’s creative and critical thinking, balancing the need for both the children and adults to lead the learning. Always work towards the following specific goals to help keep within the framework: †¢Personal, Social and Emotional Development, helping to build confidence, concentration, independence and respect. †¢Communication, Language and Literacy, developing speaking and listening skills and beginning to read and write. †¢Problem Solving, Reasoning and Numeracy, focusing on number work, mathematical ideas and thinking. †¢Knowledge and Understanding of the World, helping children investigate and think about their place in the world. †¢Physical Development, relating to developing physical skills and understanding. †¢Creative Development, centred around building children’s imagination. †¢Welfare, ensuring we are all aware of our responsibility for children’s welfare. We will look after your child properly and help them to stay healthy. We also ensure the Red House is a safe and positive place for children

Internet is backbone for data storage, access and transfer. According to some reports and IBM confirmed that information transfer and data generation has increased, in 2018 alone 2.5 quintillion bytes of data is being generated daily across multiple devices all connected through internet (Marr, 2018). So, considering this huge data accessed across multiple devices, data being the valuable resource for government and other organization to perform, which add more vulnerable access points. Data integrity means making sure the validity, accuracy and trustworthiness of the information is maintained throughout the data lifecycle. Protecting data against the breaches and attacks is the utmost importance, to maintain and ensure customer trust in the business. Improperly maintaining and handling huge data is also considered risk when exposed to several factors including software bugs, human error, virus, provisioned access to the database. Data manipulation is one of the major risks involved during data breaches. Incorrect data reduces the efficiency and also decreases the confidence on that organization. Don’t waste time! Our writers will create an original "A Data Integrity Issue" essay for you Create order The ultimate goal for a data breach can be data manipulation, to compromise the accuracy of the data rendering it useless and introducing fabricated events doubting very existence of reality. The industries which are badly traumatized with these breaches belong to all domains communication or social media, healthcare financial institutions, military, utilities, technology, transportation, etc,. Though data breaches are inevitable and often happen, but it matters how much information is compromised during the attack. Just consolidating, data breached in 2015, shows that more than 100 million patient records are compromised in the data breach. Healthcare is highly susceptible for the data breaches because the nature of data sensitivity. Accuracy in patients record is highly required, Think of a situation where patients medical events have been partially or fully modified. So a patient record with a chronic illness has been modified to a common flu and is treated accordingly or it can be vice versa. That could lead to serious issues w.r.t patients health stats and could lead to disastrous event. Major responsible lies with the healthcare/hospitals to deploy strong defense systems against these kinds of attacks. According to the reports, yahoo was one of the biggest and topmost data breaches occurred in the 21 century which accounts to more than 3 billion user accounts being stolen. The hackers obtained information about emails, passwordencrypted or unencrypted, security questions. Imagine the hacker had the information and could use that to change linked accounts for example, bank accounts notification to the email, utility bills, credit cards, etc,. Though the company had little to disclose about the data integrity during the breach, it was hit with class action lawsuit which costed company millions to pay for and also offered its customer with free monitoring services. [2] Not only the above mentioned communication and health care, all part of the industries are exposed to some or other kinds of attacks including defence, utilities, transportation, technology and education. Defense is critical part of maintaining secure environment of a country. Based on a news article posted on December, 2017, states that US DoD (Department of defense) critical intelligence data has been compromised due to data breach. Information leak corresponds to intelligence data gathered on US military and political leaders [4]. Consider, If any of those secret records or data is manipulated which are used for strategic decision making, how efficient would that be considered, when data accuracy is unknown because of the system breach and that couldnt be verified due to the fact that its highly sensitive and confidential in nature. This could lead to serious escalation in the global community or state wide chaos. Even the companies which provide security services against threats for web based application did fall for data breach, VeriSign never disclosed the attack but based on the some reports that company did had a data breach in 2010 and its still unclear how much hackers gained access to privileged systems and information[2]. The risk factor in any domain is much larger when it carries more sensitive data. Data attacks tend to increase in recent years showing a trend that most of these data attacks are sort out based on the calculated monetary value of the data, multiplication factor between sensitivity, demand and risk factor. Hackers demand ransom through crypto currency (bitcoin) to decrypt the data but its always uncertain how much data is accurate. These attacks cannot be totally avoided but cybersecurity agencies are making efforts to secure data to make sure the data integrity is not lost in those attacks. Few ways to reduce the risk of data integrity would be: Reduce human errors during registering data. Audits regular audit to verify and ensure security systems are in complaint with the industry standards. Electronic data audit with time stamp as a digital signature would be a flag to ensure when the data was modified. Encryption Though encryption is not an efficient concept when comes to the data integrity. The encrypted data can be decrypted modified and encrypted. Which does prove a valid method? But, moderate level of security is never unnecessary. Limited access enforcing limited access to the data. Monitoring services these application doesnt prevent but at least monitor the records for any changes and notifies the consumer. Update and patching regular update and patching will ensure better protection from recent or known security threats. Backup All IT companies opt for data backup. Which will ensure better assessment of the data integrity loss before after the cyber-attacks? Though these are always hosted in a remote location for better management of resources. Governments and organizations are combining efforts (monetarily, technical manpower, etc.,) to provide secure data environment, but its very unclear how many years would that take for implementation based on the rapidly changing technological developments.
