Contributions of Science in Maintaining World Peace Essay Example for Free

Contributions of Science in Maintaining World Peace Essay Science has made great progress in recent times. Through science man has been able to conquer nature. He has acquired control over land, air and water. Time and distance have no meaning in this sputnik Age. Some people think that science is responsible for wars. It has placed in the hands of the man extremely destructive weapons. They may ruin the world completely. It may be true to some extent. But science has also contributed a lot towards world peace. Today very fast means of transport and communications are available. Armies can be moved from one place to another in no times. These forces check the advance of an enemy. Thus war is prevented. Big wars break out due to certain causes. Poverty, disease, hunger, etc. , are enemies of mankind. Some countries are rich while others are poor. Scientific inventions have given us valuable machines. With their help production has been increased manifold. Even the backward and poor countries have now begun to enjoy a better standard of living. The contribution of science to medical science is well known to everyone. Wonderful drops like penicillin, streptomycin, Chloromycetin, etc. , have been discovered. They have ensured long and healthy life to the people of the world. By removing such causes of war, science has helped in reducing the chances of a world war to the minimum. Small sparks lead to big conflagrations. Similarly minor internal disturbances within a country sometimes lead to big wars, but now-a-days the police and military can be sent to the spots of trouble within no time. Thus, internal peace is far more secure today than it ever was. Science has given very effective means of propaganda. The Radio, the Television, the News paper and the cinema are very powerful means of propaganda. Through them, the people of the world can easily know the horrible effects of modern warfare. Through cinema, pictures of horrors of war are shown to the people. Thus public opinion is created against war. This also helps in preventing war. Science has not reached the limits of its inventions even now. It is making even more starting inventions. It is now busy in acquiring control over outer space. Furthermore, man is today more conscious of necessity of world peace than ever before. He has begun to use his knowledge of science for peaceful purposes. Let us be optimistic that science enables us to banish war completely in the near future.

Blurred Boundaries in Susan Glaspells Trifles :: Trifles Essays

Blurred Boundaries in Trifles  Ã‚     Ã‚  Ã‚   In her landmark feminist play, "Trifles," Susan Glaspell offers a peek at the complicated political and social systems that both silenced and divided women during their struggle for equality with men. In this simple but highly symbolic tale, a farmer's wife, Minnie Wright, is accused of strangling her husband to death. The county attorney, the sheriff, a local farmer, the sheriff's wife and the farmer's wife visit Minnie's farm house. As the men "look for clues," the women survey Minnie's domestic environment. While the men scoff at the women's interest in what they call "trifles," the women discover Minnie's strangled bird to realize that Minnie's husband had killed the bird and Minnie had, in turn, killed him. They bond in acknowledgment that women "all go through the same things--it's all just different kind of the same thing" (1076). As their horror builds and the women unravel the murder, they agree to cooperate with one another, conspiring to protect Minnie against the men by hiding the incriminating "evidence." Women's slow reluctance to cooperate across class even in the face of male oppression, as depicted in Glaspell's play, symbolizes the difficulty women had in creating a united "cross class sisterhood" when struggling for suffrage during the Gilded Age. This class conflict was exacerbated by the socio-economic dynamics of the day. Middle class women often employed working class women in their homes as servants. Employing women with hypothetically oppressive wages in their "private lives," while at the same time fighting for the economic freedom of all women in their "public lives" placed middle class women in a hypocritical bind. As historian Lois Banner reports, "In the 1900s and 1910s there was an outpouring of writings on the so-called servant problem--the shortage of women willing to work as cooks and maids. . . .It was not simply that they [servants] were expected to be paid long hours and were not well paid; they were subject to the whims and status anxieties of their mistresses " (52). The control that middle class women reportedly bestowed upon their domestic laborers extended into the larger picture; much of middle class club work focused on the "reform" of working class women. The imposition of middle class values onto working class and black women's lives alienated these women--making the feelings of sisterhood necessary for solidarity, nearly impossible. As historian Nancy Hewitt explains, "When 'true women' [i.

International Staffing Policies Essay

Ethnocentric is a staffing policy that is used in companies that has primarily international strategic orientation. This policy is generally adopted by headquarters by sending employees from the home or parent countries to the host country. This approach is used best in some situations such as, a team is sent from the home country to help setting up a new plant as well as train subsidiary personnel to use new system. The benefit of having staffs from home country abroad is that employees may gain experiences worldwide in order to become higher level in management of their headquarters because international managers require broad perspective and international exposure. For the example of Ethnocentric policies have McDonald’s. McDonald’s follows the ethnocentric orientation model. This requires an American management culture in all world’s areas inside and outside the company (HRM, production method, training, motivation†¦) McDonald’s has created it own world center for training: The â€Å"Hamburger University†. Headquartered in Oak Brook, Illinois (USA). It offers training programs exclusively for McDonald’s employees. These staff, coming from over 119 countries, represents the â€Å"McFamily†. The training program of the â€Å"Hamburger University† aims to develop the McDonald’s staff at all levels of the organization. it also aims to train people for a long career at McDonald’s, as the policy is based on long-term career’s concept and strong possibilities of change and development within the group. It promises simple teammate to move up the ranks quickly. This is a crucial point for McDonald’s HRM’s communication. I n Europe and in spite of cultural diversity, this model demonstrates its large success. Polycentric is the policy involved hiring and promoting employees who are citizens of the host countries that the subsidiary is operated. This policy is best used when companies want to keep hiring cost low. Moreover, employees who are hired at subsidiary level would not have any problem adapting to the culture. Communication is smooth within the operation. For the example of Polycentric policy: Starbucks Through a flat and flexible structure, Starbucks empowers employees to make decisions without management referral and are encouraged to consider themselves as a part of the business. This point is issued by company’s corporate culture and such work environment has positive ripples on employees’ motivation. This principle increases the involvement and the commitment of each employees from subsidiaries and makes them feel necessary for the company. This high level of autonomy allows workers to be more innovative and to take more initiatives. Thanks to its structure and to the empowerment of its employees, the company has managed to facilitate the exchange and the transversal communication, which allows it to react rapidly to the customers’ needs or to cope with more effectively with problems. Starbucks CEO and the board of directors wanted the mission statement to convey a strong sense of organizational purpose and to articulate the company’s fundamental beliefs and guiding principles. They also pay attention to employees’ and customers’ concerns to make the mission statement evolve. Indeed, these mission statements are based on several principles that consider the interests of customers, communities, employees, shareholders, and ecological considerations in all aspects of their operations. Geocentric staffing approach is used when companies adopt a transnational orientation. It is best used when companies need the best personnel to work at subsidiary. Employees are selected regardless where they come from. This staffing strategy is reliable for all subsidiaries because best employees are selected and sent from the company’s worldwide network. For the example of Geocentric staffing have: Volkswagen The challenge of this joint venture was in harmonizing the Czech culture with the Volkswagen’s (VW) culture. The formation of the new corporate culture has gone through three stages: To install this VW culture in the Czech plant, policy measures varied. For example, information was disseminated concerning the activities in all sections of the company, including in the head office, training was implemented at VW and VW were assigned to the VW factory in the Czech Republic to spread the to VW company philosophy. The main problem centered on the difference between the socialist mind set and the VW culture. To resolve the problem, key positions were entrusted to employees from VW, trained in the dual system. The creation of a uniform corporate culture in a multicultural environment is a very important strategic task. The solution was to link the different work attitudes with different business structures for a new unit to be reborn. Then, all participants would be satisfied. Staffing Approach Strategic Appropriateness Advantages Disadvantages Ethnocentric International Overcomes lack of qualified managers in host nation Unified Culture Helps transfer core competencies Produces resentment in host country Can lead to cultural myopia Polycentric Multidomestic Aleviates cultural myopia Inexpensive to implement Limits career mobility Isolates headquarters from foreign subsidiaries Geocentric Global and translational Uses human resources efficiently Helps build strong cultre and informal management network Expensive

Blocking Diode Is Useful Tool For Limiting The Direction...

Blocking diode The blocking diode is a helpful tool for limiting the direction energy can flow through a wire to just one direction. It uses a semiconductor P/N junction achieve this behavior. The diagram shows a simple setup with two panels charging a battery (for simplicity no controller is shown) with a blocking diode in series with the two panels, which are also wired in series. When the sun shines, as long as the voltage produced by the two panels is greater than that of the battery, charging will take place. However, in the dark, when no voltage is being produced by the panels, the voltage of the battery would cause a current to flow in the opposite direction through the panels, discharging the battery, if it was not for the blocking diode in the circuit. Blocking diodes will be of benefit in any system using solar panels to charge a battery. Blocking diodes are usually included in the construction of solar panels so further blocking diodes are not required. Most photovoltaic solar panels are used to charge a battery during the daytime. Nearly all panels come equipped with a blocking diode. The diode prevents DC current from flowing backwards from the battery bank into the panel at night. The usual blocking device of choice is a schottky diode with a typical 0.5v voltage drop. In some large panels, which can often source over 4 Amps of current, the power loses due to this voltage dropShow MoreRelatedGsm Based Anti Theft System11765 Words   |  48 Pages 4.5 MICROCONTROLLER (AT89S52/C51) 4.6 GSM COMMUNICATION 4.7 GSM MODEM 4.9 SMART CARD MODULE 4.10 KEYPAD 4.11 LCD DISPLAY 4.12 MAX-232 4.13 DB9 CONNECTOR 4.14 ENERGY METER 4.15 BC547 4.15 OPTOCOUPLER 4.16 1N4007 4.17 RESISTOR 4.18 CAPACITOR 5.
