Exploring the Logic of Experimental Design Assignment

Exploring the Logic of Experimental Design - Assignment Example Experiments are conducted by carrying out research studies, which attempt to put together information that is pertinent to the aims of the experiment. According to Jackson, the accomplishment of an experiment’s purpose is determined by its design and the way it is executed. Formal experiments evaluate physical entities while other modes of experimentation involve carrying out studies that involve observation and statistical surveys. The design of an experiment determines the feasibility of the intended results to the subject of the experiment, which makes experimental design a crucial factor in all analytical work (Scott, 2010). This paper seeks to highlight and explore the logic of experimental design, and how to apply them to create designs used in analytical research. Question #2 Experimental design is closely associated with methodology which are the steps taken to accomplish the task set out by the experimental design. An experiment is an inquiry into the intrinsic featur es of a subject, and it this inquiry requires a predetermined process of execution for it to serve its purpose (Jackson, 2012).The development or creation of an experiment stems from lack of information pertaining to the nature, function or purpose of an entity. Thus, this uncertainty and lack of knowledge prompts activities that are geared towards establishing and information concerning the unknown. Methodologies are ways of carrying out these activities, and they give rise to experimental designs that ensure these activities are purposely oriented. All endeavors that are carried out by man in an effort to gather information about a subject can be considered experiments or studies. This is because the sole purpose of an experiment is to account for or discount the nature and existence of a phenomenon. An experimental design accomplishes its purpose by ensuring that the methodology adhered to in an experiment is geared and oriented towards garnering the appropriate results in accord ance to the research hypothesis. Research hypotheses are the questions that experiments seek to answer by confirming their assumptions or disapproving their postulates. Question #3 The major advantage of experimental designs is that when they are properly conducted, they have the ability to illustrate causality. This is achieved by the degree to which the experiment’s parameters manipulate exposure to independent variables and elimination of confounding variables. For a study to qualify as a true experiment, the methodology should be designed in such a way as to exclude dependent variables (Scott, 2010). This is an aspect of experimental design that can be applied in educational studies to determine the cause and effect of both external and internal factors in an educational system. A disadvantage associated with experimental designs in an educational study is that they are difficult to design because they require a lot of human energy and resources. To effectively design an experiment focused on an educational system, it requires taking the behavior of the concerned parties, and in this case students, into the context of the experiment. This raises some hard to answer questions based on the ethical and moral consideration of the experimental group (Trochim, 2008). Question #4 Experiments are conducted using independent and dependent variabl

ASTRONOMY - Essay Example The gravitational force will be greater if the object’s mass is greater. 7. Terrestrial planets are those that under the asteroid belt: Mercury, Venus, Earth and Mars. Jovian Planets are Jupiter, Saturn, Uranus and Neptune. Terrestrial planets are much smaller in size when compared to Jovian Planets. Jovian Planets take much longer time for revolving around the sun and rotating in their own axis. 8. Comets are made of ice, rock and different organic compounds where as meteorite is made of space rocks that are left by comets. When meteor enters earth’s atmosphere it ignites, which is called as meteor and when it hit earth it is called as meteorite. 9. One of the important theories for continental drift and plate tectonics is that Earth is constantly moving (revolution and rotation) and the landscapes have to adjust themselves to this phenomenon. Because of this process continental drift and plate tectonics are occurring. When carefully observed on globe the continents are once upon a time were one huge landscape. 10. The major surfaces of moon are craters, highlands, lighter and darker areas. The temperatures on lighter areas are very high and on darker areas very low. It is believed thousands of centuries ago moon was covered with volcanic eruptions. 11. Venus is much closer to sun than earth. That is the reason its atmosphere is very hot compared to that of earth. Most of its terrain consists of volcanoes that are taller than Mount Everest. Lava flows like a river in

Outline and discuss the evolution of CSR, including its history, role Essay - 1

Outline and discuss the evolution of CSR, including its history, role in the financial crisis and prospects for the future. Supp - Essay Example The topic of social responsibility is a highly debated one, as several theorists think that â€Å"business is obligated only to make profits.†2 On the other hand, many believe that all business entities have a social obligation it is bound to fulfill. However, there is no denial of the fact that while operating to make profits, a business organization has to ensure that they keep the interest of the society and environment in mind because basically the revenues they make have to primarily derive from the same society and environment. Definition: Corporate Social Responsibility can be defined as the â€Å"relationship between global corporations, governments of countries and individuals citizens.†3 CSR is also encompasses the relationship between corporations and their stakeholders. The EU Commission further defines CSR as a concept where â€Å"companies integrate social and environmental concerns in their business operations†4 as well as during their interactions with stakeholders on a â€Å"voluntary basis.†5 Thus, in simple terms it is the responsibility corporate organizations have towards the society they work and operate in. Furthermore, this responsibility is not limited to the present generation in a particular society, but also extends to coming generations, that is the â€Å"future members of the society.†6 CSR is greatly related with â€Å"corporate citizenship, business responsibility, business reputation, ethical corporation, sustainable business†7 etc but is different from them. The CSR approach believes that stakeholders such as â€Å"consumers, employees, the community at large, government, and the natural environment†8 are supposed to be given a stronger focus. Social responsibility of the firms basically stems from the fact that they are using the natural resources available in the area where they function. Thus, they are bound to give something back to the society. In the present day, the wellbe ing of society has become increasingly important, and community is given the main priority in all spheres. In such a community centered world system, the question of who is responsible to safeguard the interests of the people cannot simply be answered by government. While government has a key role, the growing private sector companies including corporate entities need to focus not only on making profits, but also consider the impact of their operations within the society. History and Evolution of Corporate Social Responsibility: The basic idea of CSR has its roots in the era before the birth of Jesus Christ and is first seen when in â€Å"1700 BC†9 the ancient Mesopotamian ruler brought into practice a code that imposes punishment on â€Å"builders, innkeepers or farmers†10 by death if as a result of â€Å"their negligence†11 any inconvenience is caused to local citizens. The people engaged in any trade related activities have to abide by this code, not merely b ecause they feared â€Å"legal consequences†12 but because of their strong sense of â€Å"moral conviction.†13 On the other hand, ancient Roman senators were upset with the fact that businesses were unable to provide adequate taxes in order to â€Å"fund military campaigns,†14 therefore unsuccessful to â€Å"contribute to the war programme.†

Social Welfare Program Essay Example | Topics and Well Written Essays - 1250 words

Social Welfare Program - Essay Example This essay stresses that the social security welfare program has several goals that it intends to meet. For instance, they aim at providing for the needy in the community. They are also determined in providing the economic security that the American people desperately need. Doing so would require them to maintain maximum freedom in the economic lives of the American people. This paper declares that the provision of social insurance has been instrumental in the success of the program. Social insurance addresses the concept of economic security. The basic behide social insurance is that people make contributions to a centralized fund. The fund provides income to individuals who happen to find their income un-sustaining and give back after a period of time. Social insurance emphasizes on the social suitability of benefits. In its system, individuals who previously earned less income receive a higher benefit than those with higher earnings. It is this mechanism that has helped the system to grow in terms of benefits which is not applied by private insurance organizations. Social welfare has a number of aspects that contribute to its effectiveness. Provision of social insurance is one of those strengthening aspect to the program. Social insurance has been instrumental in empowering citizens. This is because it is a contribution made by people so that it can helps them get income later on. The concept provides a form of economic security to people. It enables them to provide for themselves even at old age when they cannot work.

International business management report - Essay Example The involvement of cross functional teams and different stakeholders therefore require project management to be governed in effective manner. This report will also include evidence from the various reports of National Audit Office on the success of implementing Shared Services in UK and will take practical insights from the same. ManCo’s decision to implement a shared service to manage certain business processes will require a systematic approach towards understanding how the overall dynamics of project management work besides how leadership can effectively contribute towards the success of the project. More collaboration needs to be on the development of agile systems which are not overly complex as well as fulfill the requirements of the internal customers of the project. This report will provide analysis and insights into how ManCo can manage the overall project of initiating the required changes in the processes. This report will further discuss about critical issues and p rinciples related with the successful project management. Key Principles of Project Management One of the key principles a project follows is the clear definition of what project is and how much the project manager is actually responsible for. In order to successfully launch the project of managing the shared services across different locations, it is important first to actually define what this project is and what it intends to achieve. Practically, however, project managers fail to clearly define the projects and determine the accountabilities for this. Various reports by National Audit Office (NAO) suggest that failure to clearly identify the purpose of project and who will own it can increase the cost for project managers. Definition of the roles and accountabilities is also another key principle ManCo must first determine. The people involved in the overall project, how cross functional teams will be formed and what will be the role of each member must be defined initially in o rder to avoid conflicts at the later stage. In order to successfully manage all the stakeholders, it is critical therefore that the roles and responsibilities of people to be involved in the overall project.( Brewer,& Strahorn, 2012) Another important and critical principle is the preparation of plan and the discussion of the same with that of the managers. As a project manager, I would therefore focus more on discussing the project and its deliverables and justifying various activities which will be undertaken in order to centralize HR, Finance, Payroll and other activities across different locations. Dissemination of information and properly communicating to all stakeholders is another important principle which needs to be followed. Not informing all the stakeholders involved may create further conflicts of interests and hence the overall governance of the project may become difficult to achieve. National Audit Office in its one of recent reports has suggested that there is a need to have in-house capability along with the business and technical expertise to manage shared services. As such, the project management principles for shared services require that in-house capabilities must be developed rather than outsourcing the shared services. Focus should be on improving the in-house efficiency and to leverage the same with tha

Heat and temperature Coursework Example | Topics and Well Written Essays - 1000 words

Heat and temperature - Coursework Example As the kinetic theory of matter deals with the speed of particles of matter then the determination of particle speed can help us to study the kinetic theory of matter in greater detail. Therefore, the study of heat helps us to study the kinetic theory of matter. Heat is a form of energy that is transferred from one body to another in a system. When a warmer body is placed along a colder body, the heat from the warmer body will tend to go to the colder body. This process will continue until the energy of both systems becomes equal. (Reif, 2000) There are three modes of heat transfer better known as conduction, convection and radiation. Heat energy is important as it has direct relation to the physical state of a system. The addition of heat energy excites the particles present in a system. This enhances their random motion. Similarly, the removal of heat energy depresses the particles in a system which decreases their random motion. Temperature is a measurement that helps to quantify just how hot or cold a system is. Like other forms of measurement, the temperature scale is relative too. Temperature is used to measure just how much heat is being talked about. (Chang, 2004) Temperature helps to classify is there is some difference in heat between two bodies. This difference can be used to estimate the amount of heat transfer that will occur between both systems. Heat as already mentioned is a representation of the state of particle’s motion in a system. However, the speed of particles cannot be judged from one particle to the other. Therefore, there had to be some method of measuring the heat contained in a system. When a system contains heat, the particles in the system display random motion. This random motion is dealt with as the kinetic energy of the system. The speed of the particles and their weight are used to express the kinetic energy of a system. The total kinetic energy of a system is the heat content that resides in the system. This heat can be measured in reference to temperature. Temperature expresses the average measure of the heat contained in a system. Temperature expresses the willingness of a system to transfer heat energy if placed along a system with lower heat energy. Therefore, temperature is a method of measuring the total heat content of a system. (Kittel & Kroemer, 1980) Often heat and temperature are assumed to be one and same. However this concept is entirely false. Heat represents the total of a certain kind of energy possessed by a system. The temperature is only a method of measuring this energy possessed by the system. For example, if there were water standing in a pool which represented heat, then the measurement of its depth would be equivalent to temperature. Therefore, heat is a property possessed by a body while temperature is a measure of that body. Heat is possessed by all systems to varying degrees and is transferred by all systems to varying degrees too. However, the amount of heat retained by a system and the amount of heat transferred by a system vary in large part from one material to another. As an example, it is known that metals are good at the transfer of heat and insulators such as rubber are bad at transferring heat. The tendency of a body to both retain and transfer heat can be measured and expressed as well. This is also considered to be a property of the body and is known better as the â€Å"

Dance Critique Essay Example for Free

Dance Critique Essay Ballet â€Å"Cry† simply showed to us real life of all African women. Every single American people know what kind of life they went through. Therefore it touched their heard. Alvin Ailey’s â€Å"Cry† presented wonderfully combined movements, technique and emotion. Ms. Donna Wood uses tragic face, a mask of sorrow. It is a face born to cry, but when she smiles it is with an innocent radiance, joyfulness that simple and lovely. She never tries consciously to please an audience. He was not only concentrating in movements and physical performance, but also using flowing white gown with a long white scarf for the dancer. A long sleeve white blouse is slim, to show the dancers body. Especially her movement and technique. It made dance more interesting to audience. This beautiful piece of modern dance consists of three sections. Ms. Donna Wood performed solo dance for 16 minutes from section to section. Her ways through the dance are different in movement quality that she gives to each passage. In this tribute to black women, the free sprit or the African women comes through in the energy of her dancing. In the first section started on dark stage, only dancer has a spotlight. Music was soft and smooth. We could hear only piano while dancer was walking forward in straight posture with graceful movement. Started with smooth then mixed up with sharp and pedestrian movements. She uses long white scarf on the floor by showing to us hard work. In dance we say †low† level. For example, she scrubs the floor, uses as a headband representing to carry something. Emotionally sad ness, she worked hard, she contracts in pain, she flutters her hands like captive birds and she tried to get out of struggling life, but she never gives up. There is pain here as well as power, and the music, so oddly modern to me. In the end of the first section she starts picking up her dress, shows her leg and fills the stage. Basically first part of work showed their slaver life and unhappy living. In the second section background lightening became blue and the stage color gets brighter. Still we can see and feel some dark sides of lightening. Music tempo was faster and stronger and Ms. Donna Wood has stronger movements. The most interesting in this section was singing human voice. She starts to sing and has a little smile on her face. Most of her movement shape was very sharp, edgy and angled especially her arms at first. She represents them to be united and get free. By jumping and crossing arms, she sinks to earth and then she rises. Strong steps and ecstatically raised arms, dances freely off the stage, toward freedom. In short, in this part of work the young women life get better and better, but still it wasn’t completed. In the third section Ms. Donna Wood looks like an African goddess and her body has an unexpected gracefulness. Even stage color was bright reddish, warm atmosphere around the dancer, like a sunrise in the morning. Stage would fill with colors. Music and performer are singing together. A sound of music tempo gets faster. She has the happiest face ever, no pain and no slavery. She jumps, she swings her leg and arms, and even she pulls her dress up and shows her leg an entire dance. Sound and lightening create the environment and good mood. She uses high level of dance than in previous two sections. She moves in between melody. I liked how she uses the stage in this section. She has the high energy to cover so much space by dancing alone. Finally, Ms. Donna Wood gives us her version of black power and black pride in â€Å"be free†. In conclusion, the solo dance â€Å"Cry† performed by Ms. Donna Wood has 3 sections for 16 minutes work. An African women’s journey through the agonies of slavery to an ecstatic stage of grace. She dances with an articulated beauty, serene, together and womanly. She holds herself a little aloof from the audience, but she is reserved rather than shy. She is wonderfully proud, from the poise of her head set perfectly on a long, strong neck. The simplicity of the staging was exemplary, and the lighting made most telling contribution in varying the effect of each section and matching work. Ms. Donna Wood’s angular, cleanly shaped gestures slashed through the air for an exciting finale. Alvin Ailey made it for her and as a birthday present for his mother.
