Contextual investigation - Essay Example It might be troublesome tocontrol the workers in the organization if the selection representatives neglect to consider the interests of the organization in their enrollment work out. As a staffing proficient in the HR office, it is critical to speak to the organization’s intrigue. It ought to be noticed that every association has its own way of life and this decides factors, for example, conduct of representatives, their presentation just as essential qualities that depict the association. Fundamentally, â€Å"organizational culture alludes to an arrangement of shared importance held by the individuals that recognizes the association from other organizations,† (Robbins, 1993, p. 602). In an offer to accomplish its set objectives and destinations, it very well may be seen that there are sure key qualities that the association esteems. These shape its way of life and they become dug in it its tasks. The other point of speaking to the organization’s interests while recruiting representatives is that it causes the HR work force to ensure that the correct individuals are employed. The staffing officials are in a situation to survey the abilities of the applicant and discover in the event that they will be perfect with the organization’s culture and hard working attitude. Every association has its own objectives and destinations and there are various systems that can be actualized so as to accomplish these. Be that as it may, this must be conceivable if the association has a plainly laid out culture that shapes the conduct of the individuals inside the organization. There are sure qualities that are relied upon to be trailed by every individual in the association and these ought to be spoken to from the beginning through the enlistment and area process. The other centrality of perceiving authoritative culture is the component of gathering accentuation. This alludes to how much work exercises are sorted out around bunches as opposed to people (Robbins, 1993). This clarifies why it is imperative to speak to the interests of the association. Gathering attachment is

Community Psychology and Society

Community Psychology and Society Theories Print Community Psychology Explores How Individuals Relate to Society By Kendra Cherry facebook twitter Kendra Cherry, MS, is an author, educational consultant, and speaker focused on helping students learn about psychology. Learn about our editorial policy Kendra Cherry Updated on December 11, 2019 pixdeluxe / E+ / Getty Images More in Theories Behavioral Psychology Cognitive Psychology Developmental Psychology Personality Psychology Social Psychology Biological Psychology Psychosocial Psychology Community psychology is a specialty area concerned with how individuals relate to society. Have you ever wondered how people can become more active contributors in their communities? Or do you ever think about how community issues can impact the health and wellness of individuals? These are both major topics of interest within the field of community psychology. This is a fairly broad and far-reaching subject within psychology, synthesizing elements from other disciplines including sociology, political science, public health, cross-cultural psychology, and social psychology. Psychologists working in this field look at the cultural, economic, social, political and environmental that shape and influence the lives of people all over the globe. The focus of community psychology can be both applied and theoretical, but it is oftentimes a mixture of both. While some community psychologists conduct research on theoretical issues, others take this information and put it into immediate use to identify problems and develop solutions within communities. History of Community Psychology Community psychology began to emerge during the 1960s as a growing group of psychologists became dissatisfied with the ability of clinical psychology to address broader social issues. Today, many recognize a 1965 meeting of psychologists at the Swampscott Conference as the official beginning of contemporary community psychology. At this meeting, those in attendance concluded that psychology needed to take a greater focus on community and social change in order to address mental health and well-being. Since that time, the field has continued to grow. Division 27 of the American Psychological Association, Society for Community Research and Action (SCRA), is devoted to the subject of community psychology. Several academic journals  are also devoted to the topic, including the American Journal of Community Psychology, the Journal of Community Psychology and the Journal of Community Applied Social Psychology. Community Psychology at Work Some things that a community psychologist might do include: Finding ways to help disadvantaged or disenfranchised individuals feel more connected with their local communitiesUnderstanding social issues among minority groupsDeveloping, implementing and evaluating action-oriented community-based programsBuilding relationships between individuals and community groupsEvaluate organizations, governments, and communities in order to promote participation and diversityCommunity psychologists can be employed in a number of areas including education, government, nonprofit groups, community organizations and private consulting. Within the educational system, community psychologists often work at colleges and universities to teach courses and conduct original research. In a government setting, they may work in health and human services for local, state and federal governments. Related Fields People sometimes confuse community psychology with related fields such as  social work, cross-cultural psychology, and social psychology. While community psychology has many similarities to related fields and often draws upon these disciplines, it is important to note some major distinctions. For example, community psychology is centered on action and solving problems much like clinical psychology. However, clinical psychology tends to have a greater focus on solving individual problems, while community psychology is devoted to understanding the underlying social issues that contribute to these problems. Community psychology also takes a holistic, systems-based approach to understanding behavior and how people fit into society, much like related fields such as sociology and social psychology. Community psychology tends to be more centered on applying psychological and social knowledge to solving problems, creating real-world solutions and taking immediate action. Like public health and mental health counseling, community psychology is also focused on the prevention of problems and the promotion of health and well-being. It also has a very strong research-oriented component. Community psychologists often perform original research, develop theoretical frameworks and then apply this knowledge directly within public and private communities. As you can see, community psychology overlaps with a number of other disciplines. However, it has its own unique and important contributions to make. The major goals of this field are to create new ways to empower people within their communities, promote social change and diversity, promote individual and community well-being and prevent disorder. Training and Educational Requirements for Community Psychologists Most community psychologists hold at least a masters or doctorate degree in psychology. There are some community psychology programs available, but other students opt to earn an interdisciplinary degree or a general degree with a focus on community psychology topics. Some of the coursework that an aspiring community psychologist should take includes: Social behaviorResearch methodsStatisticsPublic healthOrganizational developmentGrant writingDeveloping prevention programsDevelopmental psychologySociologySocial problemsCommunity development Training and education in community psychology focus on both research and application. Graduate students receive extensive training in research methods and social statistics, as well as how to put this information to practical use through developing action-oriented community programs.

Contribution Of Women In The Civil War - Free Essay Example

Sample details Pages: 6 Words: 1910 Downloads: 9 Date added: 2019/05/08 Category History Essay Level High school Tags: Civil War Essay War Essay Did you like this example? When it comes to the evaluation of the significance of the Civil War, many tend to put emphasis on the relationship between the races as well as the desire of one party, the Confederacy, to maintain the preferred social order, namely slavery. However, there is another kind of relations that is often overlooked when it comes to the analysis of this armed conflict gender relationships. While many believe that the war in question was fought by men against men, the contribution of women tends to be in the shadow and is perceived as less significant. Don’t waste time! Our writers will create an original "Contribution Of Women In The Civil War" essay for you Create order This is a serious historical injustice since when all aspects of that time are taken into account, one will be able to notice that women contributed to the war effort from both sides significantly. During the Civil War women provided war relief, served as nurses, soldiers, and even spies which makes them an inseparable part of that armed conflict. Women Providing War Relief To begin with, it is worth focusing on the place that women traditionally occupied in the society in the eighteenth century. Being deprived of a chance to get education, they usually worked as manual workers and were employed at jobs of varying difficulty[1]. It is obvious that wives of upper-class men did not work, but the important point to be mentioned here is that the division of labor was largely performed based on stereotypical gender characteristics[2]. As a result, during the Civil War women would often make a contribution that they did during the peaceful times, but on a larger scale: they would cook food, repair clothes, take care of the laundry and so on. No matter how insignificant one might see this, this kind of war effort was essential for keeping an army operational. That is why there is a lot ofinjustice in the fact that this contribution of women has been overlooked by many. In addition to that, there were also activities that contributed to the war efforts and were not considered to be a stereotypical womens work. A good example is Sanitary Fair which was hosted in Chicago in 1863: this was an event that was designed to raise money for the army[3]. One should point out that at the time this was considered to be a significant step in letting women do some important social job as prior to that women also organized some fund-raising events, but they were not directly linked to any significant social issues. Therefore, the ability of women to find money for the army was greatly valued at the time because money was needed to ensure that the funding did not stop which contributed to the ultimate victory of the military forces. Women Serving as Nurses Now, it may be logical to turn to another aspect of the contribution of women to the war efforts serving as nurses. In spite of the fact that today female nurses on the battlefield are seen as something ordinary, it was quite a big novelty at the time. Florence Nightingale set an example during the Crimean War which inspired numerous women all over the world. Many women, for example, Dorothea Dix, would become full-time nurses during the war[4]. If one develops a broad perspective on this issue, one will be able to notice that it was indeed a serious step forward since it showed that women can do something more than just their domestic chores on a large scale. Once again, it is worth mentioning that seeing women as nurses were quite unusual at the time; so, the women who volunteered to be nurses were extremely brave. However, it is not only administration of hospitals and taking care of the wounded that women did as nurses. There were numerous examples of nurses that would go the battlefield and help the soldiers under such extremely dangerous conditions. Clara Barton is one of such nurses: she took care of the soldiers not only in the hospital, but also during th? battles; that is why she received an honorary title Angel of the Battlefield[5]. The key point that needs to be emphasized here is that by allowing women on the battlefield, the military acknowledged that women were able to make a significant contribution that was highly valued. According to the laws of the time, women were banned from the military; therefore, their presence on the battlefield as nurses as close as they could get to make a direct contribution to the war effort without violating the applicable laws. Women Serving as Soldiers As it has already been mentioned, the laws of the time prohibited women from serving in the army. However, it is suggested that as many as over 400 women were able to find their way into the military by disguising themselves as men[6]. For modern day people, this might sound somewhat unbelievable; however, after all, aspects have been considered, one might find that this was quite possible. The example of Frances Clayton is quite interesting: she disguised herself as Frances Clalin and served as a soldier[7]. It is quite obvious that at the time the need for soldiers was high; so, the recruiters did not question a person who was willing to volunteer. The important point to note here is that such example as that of Clayton shows that women were dissatisfied with the place that they had in the society and were willing to make a contribution to the war effort as much as men did. It may be rather difficult to estimate the actual number of women who served in the army during the Civil War for a number of reasons. First of all, they directly violated the applicable legislation which meant that neither them, nor the army would actually report that number since it was against the rules. In addition to that, the only war for women to be discovered was when they were examined by the doctors in the hospital after they were wounded. That is why it is quite possible that many women died on the battlefield and were not ever discovered. In addition to that, they might have refrained from going to the hospital because they knew that that would destroy their disguise. All this leads to the understanding that there is evidence that many women were willing to contribute to the war effort as much as men did. Women Serving as Spies Finally, there is one last aspect that needs to be mentioned when it comes to evaluating the contribution of women during the Civil War many of them served as spied. Given all the roles that were mentioned above, namely a war relief worker, a nurse, and a soldier, one might speculate that being a spy is the most extreme role that women were able to play during the war. From the letters of Sarah E. Thompson, we know that she did her best to serve the Union as much as she could. Though she may have simply talked to some soldiers and visited balls, she was actually collecting important information that was later needed by the army[8]. That is why it is possible that womens ability to affect men and maintain interesting conversation appeared to be quite helpful during the war. The important point that needs to be mentioned specifically is that there were female spies on both sides. For example, Rose ONeal served as a spy for the Confederacy and warned her friend in personal correspondence about the importance of sending correct information, which can be used so as to counteract the Yankee accounts[9]. This shows that ONeal understood the basics of information warfare and tried to do her best to spread the truthful information about her friends so that they would get an objective view of the actions of the Confederate army. With this in mind, one might speculate that this woman was way ahead of her time because she understood the role that information played during the war. As a result, one might come to the understanding that women were able to play all kind of roles during the Civil War. Conclusion Having examined all the points that were mentioned in the paragraphs above, one is able to come to the following conclusion: during the Civil, War women assumed a wide variety of roles ranging from stereotypical to most extreme. Thus, women served as war relief workers and performed their domestic duties on a large scale. This was considered to be the most appropriate way for women to make their contribution to the war effort. Some women were brave enough to serve as nurses: they took care of the soldiers on and behind the battlefield. These women were greatly inspired by the example of Florence Nightingale. There also were women who disguised themselves as soldiers and fought with men. The only time their true identity was discovered was when they were wounded and required medical attention. Finally, the evidence shows that there were many women who served as spies. Bibliography Beard, Rick. From Civil War to Civil Rights: The Opportunities of the Civil War.

According to Socrates, Should you Obey an Unjust Law

Convicted For Living? Do we have an obligation to obey any law, no matter how unjust or evil, provided only that it is in fact a valid rule of the legal system in which we happen to be physically located? In the following composition, I am going to examine the answer to this question in accordance to what Socrates believes. The best way to understand this almost â€Å"WWSD† (What Would Socrates Do) approach is by looking at Socrates actions in the three Platonic dialogues we have read. These dialogues bring forth three possible bases for why Socrates believes one should obey the law. First, that there is a distinction between the the â€Å"justness† of a law and how that law is applied. Second, that if one willingly accepts living in a†¦show more content†¦At no point during the proceedings did Socrates deny that corrupting the youth was a criminal act punishable by death. Socrates in fact believes that it is noble to prosecute those who corrupt the minds of the youth. Moreover, i n the Euthyphro Dialogue, Socrates even praises Meletus saying that, â€Å"He [Meletus] is the only one who begins at the right point in his political reforms; for his first care is to make the young men as good as possible† (2). Therefore, while Socrates may not have necessarily agreed with the verdict of his trial, he did agree with the essence and/or idea of what the law that he â€Å"broke† was founded on. Socrates was accused of corrupting the young through the ideas he taught and the manner in which he taught them, ergo his acts were inseparable from the crime of which he was accused of. Consequently, and quite frankly rather humorously, the sheer enormity of Socrates crime could have hardly been outdone by that of any other of its time. Whereas it meant that everything Socrates had done in his life was illegal, since practically his entire life stood for the proposition that he ought to teach his philosophy to anyone who would listen. Socrates believed that the life unexamined is one not worth living.. The depth of that belief made the accusation of corrupting the young almost equivalent to being charged with the crime of having lived.

string(260) " by utilizing the Clarke transmutation, it can be written as \[ 3 \] The instantaneous beginning current besides transformed into the co-ordinates by Clarke transmutation ; Whereand axes are the extraneous co-ordinates and are on the-axis and are on the-axis\." Abstract- In this article describe the public presentation of a sinusoidal current accountant based three-phase shunt active power line conditioners ( APLC ) for power quality betterments such as harmonics and reactive power compensation due to imbalanced and non-linear tonss. The electromotive force deformations are compensated by positive-sequence electromotive force sensor and harmonic extracted from changeless instantaneous existent power control scheme, this attack is different from the conventional methods. The shunt APLC is implemented with PWM current controlled electromotive force beginning inverter and connected to the point of common yoke for extinguish the current harmonic and do sinusoidal current to the beginning. We will write a custom essay sample on Sinusoidal Current Control Strategy Based Active Power Engineering Essay or any similar topic only for you Order Now The mention current ( s ) are extracted from sinusoidal current accountant algorithm and PWM-VSI gate control signals are generated from hysteresis current accountant ( HCC ) . The relative integral ( PI ) -controller used to keep the changeless DC-side electrical capacity electromotive force of the PWM inverter. The shunt APLC is investigated in footings of order of harmonics, VDC subsiding clip and assorted parametric quantities under the assorted non-linear burden conditions. Keywords- Shunt Active Power Line Conditioners ( APLC ) , Hysteresis Current Controller ( HCC ) , Sinusoidal current accountant, Positive sequence electromotive force sensor. Introduction Power transmittal and distribution systems are criticized by power quality jobs due to the non-linear tonss, such as power convertors, rectifiers, arc furnaces and other industrial applications like variable velocity thrusts. These non-linear tonss introduce harmonic deformation in the power distribution system [ 1 ] . The current harmonics cause the malfunctions in sensitive equipment, overvoltage by resonance and harmonic electromotive force bead across the web electric resistance that consequence is hapless power factor. Traditionally these jobs were solved by LC inactive filters. But in practical applications these inactive filters introduce aging and tuning jobs, resonance, big size and it ‘s besides limited to few harmonics. The different constellations of inactive VAR compensators ( SVCs ) have been participated for solve these jobs of power-factor rectification. Unfortunately some SVCs produce lower-order harmonics themselves and response clip of some SVCs may be excess ively long to be acceptable for fast-fluctuating tonss [ 2-3 ] . Recently active power filters ( APF ) or active power-line conditioners ( APLC ) are developed for compensate the current-harmonics and reactive power at the same time due to power factor rectification [ 4 ] . The APLC has the ability to maintain the brinies current balanced after counterbalancing regardless of either the burden is non-linear and/or imbalanced conditions. The APLC can be connected in series for operate as electromotive force beginning and in analogue for operate as current beginning, but the series APF is non found in common practical usage, so this paper concentrate the shunt APLC system [ 5 ] . Controller is the sole of the active power filter and presently batch of research is being conducted and proposed assorted control schemes [ 6-7 ] . The sinusoidal current accountant algorithm is widely applied for active filter design, because simple mathematical computation, hardiness and good dynamic response. This accountant contains of positive sequence electromotive force sensor and instantaneous power theory ( p-q theory ) concept [ 3 ] . The footing of instantaneous power theory is supplying good compensation features. Current harmonics is achieved by shooting equal but opposite current harmonic constituents at the point of common yoke ( PCC ) , there by call offing the original deformation and bettering the power quality on the connected power system. This paper presents sinusoidal current accountant based shunt APLC for current harmonics and reactive power compensation under non-linear and imbalanced tonss. The shunt APLC is implemented with three stage PWM electromotive force beginning inverter and connected to the Ac mains web at the point of common matching for compensate the harmonics by shooting equal but opposite harmonic counterbalancing current. The mention currents are generated utilizing sinusoidal current accountant and PWM-VSI gate control signals are derived from hysteresis current accountant, this attack is different from conventional methods. The Proportional Integral ( PI ) accountant used to keep the dc-side electrical capacity electromotive force of the PWM inverter invariable. The shunt APLC is investigated and measured assorted parametric quantity values under different tonss. Sinusoidal Current Control scheme Shunt APLC system design Shunt active power filter is connected in analogue with the distribution supply and the non-linear tonss at the point of common yoke.

Once the circuit is stabilized, the mean value of is zero and the stage angle of the supply system electromotive force at cardinal frequence is reached. At this status, the currents become extraneous to the cardinal stage electromotive force constituent. The PLL synchronism end product currents are defined as The PLL design should let proper operation under distorted and imbalanced supply electromotive forces.

If the mistake current is exceed the upper bound of the hysteresis set ( h=0.5 ) , the upper switch of the inverter arm is turned OFF and the lower switch is turned ON. As a consequence, the current starts to disintegrate. If the mistake current crosses the lower bound of the hysteresis set ( h=-0.5 ) , the lower switch of the inverter arm is turned OFF and the upper switch is turned ON. As a consequence, the current gets back into the hysteresis set. The scope of the mistake signaldirectly controls the sum of ripple electromotive force in the end product current from the PWM-VSI.

Work and Organizations Tesla Motors

Question: Discuss about theWork and Organizationsfor Tesla Motors. Answer: Introduction The study is focusing on the change of workplace in modern organizations from 1990s to 2016. It also describes the future trends of the workplace in terms of automobile industry. The study will describe the change of workplace in Tesla Motors. The main theme of the study is focused on automation. In the service industry, online ordering process and automated answering are the most trending system of automation that are practiced in every sector of industries. Review on the Changing Nature of Work Three Points in the Changing Nature of Work In the video it is seen that the assembling facility of Tesla Motors is very innovative. Earlier the nature of the facility was different. There was more number of people in the assembling and manufacturing site when compared to modern facility site. Introduction of new technologies is responsible for the change of work patterns. Innovation of technologies not only improves the quality of the product but also it enhances the working condition of the people at the facility. The video of the manufacturing site of Tesla Motors illustrates different types of huge and small robots that help in assembling of the parts of the motors. This is a significant aspect not only in the technological point of view but also in the change in nature of the workplace. It is seen that there are 3000 workers present in the assembling facility of Tesla Motors. They are very competent so that they can handle the activities of the robots. Control of the activities and ensuring the quality of assembling of different parts of the car require talent and multipurpose skills which is present in the modern workers but are not present in the workers of 90s. The human resource department of Tesla Motors is adopting skills that are meeting the demands of the employees that include employee engagement, job designation, job enhancement, etc. Prediction of Workplace in the Next 5 to 10 years By analyzing the video of Tesla Motors it can be said that the systems of operations Tesla Motors are improved and they are focused on catering the needs of the employees as well as the customers. Prediction of changes in the workplace of Tesla Motors includes different types of improved measures of human resource management process (Cooke 2013). Apart from that, the innovation of technology will enhance more number of robots not only in the assembling section of Tesla but also in the other manufacturing locations, corporate offices, and regional offices. However, it will not only increase the responsibility of the workers but also it will build a new dimension of responsibility and competent skill sets among the employees (Gubbi et al. 2013). Innovation of the technologies will also be implemented to formulate strategies of the improved human resource management. In the coming decade, the whole operational procedures of the various departments of Tesla Motors will drastically change with the implementation of technologies in every aspect (Al Ariss et al. 2014). Implications In terms of employment related changes and employment conditions, change will be there as the whole format of working procedure of the employees. In the future decade, the skill sets and capabilities of the employees will be different from now. Hence, there would be new forms of recruitment and selection procedures for identification of right talents for the organization (Liebowitz and Frank 2016). However, there are training modules that would be formulated for the development of the expertise and skills of the employees associated with the assembling and manufacturing site of Tesla Motors. The company will have to give priority to its employees so that they can increase the productivity of the company as a whole. Innovation may lead to development of many technologies that are self sufficient. Those machines are called robots and they do not require any human assistance for performing the work. In the video, the robots used in the assembling site of Tesla Motors are very powerful. They are capable of doing things that are not possible for a single person. However, the robots have to monitor which require human assistance. This should be developed among the workers present in the different departments of the assembly location (Peretz 2013). Workplace Behavioral Issues The workplace behavioral issues that the companies in the service industry will adapt are motivation, employee engagement, decision-making and the job satisfaction. It is seen that the automation has reduced the physical labour of the employees but the mental pressure is gradually increasing day by day. However, it can be said that in the changed advanced working environment, employees should keep motivated and have the power of decision-making in the field of operations (Nabrzyski et al. 2012). HR managers of organizations should formulate strategies that would motivate the employees in performing their duties efficiently. Monetary and non-monetary benefits are to be provided so that they can give their best input to the work in order to accomplish the organizational goals. In the competitive business world, companies are not only giving priorities to the products or services but also they are giving priority to their employees (Morgeson et al. 2013). Employees are considered as ass ets of the organization. Job designs are to be structured in a way so that talented employees can get attracted to the opportunities provided by the companies of service industries. Another aspect is employee engagement. It is related to the decision-making ability of the employees who are working with the changed environment. Companies must motivate their junior or middle level employees in the decision-making process as they closely work with the different aspects of automations and technology (Brewster and Mayrhofer 2012). Conclusion The study illustrates different types of innovation developed by service and manufacturing industry. The video of Tesla Motors describes that how human beings develop robots that are highly efficient in doing heavy works. It is an example of automation in the automobile manufacturing industry. Apart from that, the robots and other automated machines are used in the assembling and manufacturing facilities of BMW and other automobile companies. Employee related aspects are also described in context of advancement of technology in a detailed manner. References Al Ariss, A., Cascio, W.F. and Paauwe, J., 2014.
