Fractional Distillation Essay

Abstract An equimolar mixture of cyclohexane and toluene was separated by simple and fractional distillation, using an empty column and a copper sponge column respectively. Using helium as the mobile phase, the distillate was analyzed through gas chromatography. The calculated HETP for the simple distillation was 8.274 cm/plate and the 3.332 cm/plate for the fractional distillation. Experimental Procedure A copper packed fractional-distillation column was obtained and an apparatus was assembled for fractional distillation. Four clean, dry fraction collectors were obtained and labeled HETP, fraction 1, fraction 2, and fraction 3 respectively. A volume of 40.0 mL of an equimolar mixture of cyclohexane and toluene was added to a 100.0-mL round bottom flask attached to the end of the distillation column. Heating chips were added to the round bottom flask in order to speed up the heating process. The 100.0-mL round bottom flask, along with the distillation column was attached to a ring stand over a heat source. The mixture was delicately heated to a boil. The first five drops were collected in the vial labeled HETP. The liquid for vial 1 began collecting when the temperature was 60 C and continued until it was 85 C. Vial 2 began collecting when the temperature was 86ï‚ °C and continued until it was 99 C. Vial 3 was collected at room temperature once the remaining liquid cooled. A volume of 1 micro-liter of each fraction, including the HEPT was added to the gas chromatography apparatus separately in order for each fraction to be analyzed. For simple distillation, the same procedure was followed using an empty, clean, and dry column.

To obtain pure ÃŽ ±-pinene, it must be separated, using fractional distillation, from the other major component   turpentine, ÃŽ ²-pinene. This company would like to switch to a cheaper and longer-lasting packing material. The objective of this experiment was to separate an equimolar mixture of cyclohexane and toluene by simple and fractional distillation, using an empty column and a copper sponge column respectively. The distillate was analyzed through gas chromatography, using helium as the mobile phase. Helium is a good mobile phase because it acts as an unreactive carrier-gas that pushes the samples through the chromatogram. This information was used to determine which packing material is most effective by comparing HETP values which based on the number of theoretical plates each material provides. Using the copper sponge as packing material in the fractional distil lation column provided a very effective separation of cyclohexane and toluene. The calculated HETP for simple distillation was 8.274 cm/plate and 3.332 cm/plate for fractional distillation. The fractional distillation was more effective because it had a lower HETP value which means that it has a higher number of theoretical plates for the same column length as the simple distillation. When comparing the purity of the major cyclohexane-rich fraction with the starting mixture (the equimolar mixture of cyclohexane and toluene) of each distillation the packing material improved efficiency by more than six percent. One way to recover cyclohexane with even greater purity would be to heat the starting mixture slowly and steadily instead of rapidly, allowing better separation of the components. Another way to improve purity is to make sure the column is properly packed (not too tight) and insulated. Different packing materials will have diverse efficiency for distillation and therefore yield different HETP values. The most efficient packing material used was â€Å"rascing rings,† which provided an HETP of 2.67 cm/plate. The copper sponge material had an HETP value of 3.3 cm/plate, followed by glass beads and coiled copper with 7.5cm/plate and galvanized steel with 12.5 cm/plate. Packing the Northern Pines Chemical Company’s 3ft fractionating column with rascing rings would provide 34.2 plates, which meets the minimum requirement for separating ÃŽ ±- and ÃŽ ²-pinene. Exercises 1) HETP=height/plates Porcelain saddles: 5 cm= (15 cm )/(x )=3 plates Glass Tube: 15 cm= (15 cm )/x=1 plate Vigreux Column: 8 cm= (24 cm)/x=3 plates Total plates= 3+3+1-1(boiling flask) = 6 plates 2) The HETP value and efficiency of separation can be affected by experimental errors. A) If the HETP sample was collected midway through the distillation, the mole fraction of cyclohexane:toluene would be much lower, which would in turn yield a higher HETP value. B) If all of the liquid distilled within 5 minutes of heating, a higher HETP value would be found again because all of the toluene would be distilled as well. This also means poor separation. C) If two packed columns were stacked over the boiling flask instead of one, the HETP value remain the same if the columns were identical because the height and number of plates would be the same.

Fecha de prioridad para obtener la green card

Fecha de prioridad para obtener la green card Tu fecha de prioridad es el dà ­a en el USCIS recibià ³ tu peticià ³n para una tarjeta de residencia. Es un dato importantà ­simo para saber cundo tendrs disponible una visa de inmigrante para ti. Si eres esposo/a, hijo soltero menor de 21 aà ±os, padre o madre de un ciudadano americano tu fecha de prioridad aparece en el documento en el que el USCIS confirma que ha recibido la aplicacià ³n. Pero realmente no es importante a estos efectos. Para ti no hay là ­mite anual en el nà ºmero de visas que se pueden conceder. Por lo tanto,  para ti no aplica el resto del artà ­culo. Por el contrario, si eres: cà ³nyuge de un residente permanente legalhijo soltero menor de 21 aà ±os de un residente permanentehermano de un ciudadanohijo soltero mayor de 21 aà ±os de un ciudadanohijo casado de cualquier edad de un ciudadano entonces sà ­ que la fecha de prioridad es muy importante para tu caso. Sigue leyendo. Los cupos anuales para tarjetas de residencia por razà ³n de familia Si ests en uno de los casos anteriores, para cada aà ±o fiscal hay un là ­mite en el nà ºmero de tarjetas de residencia que se pueden aprobar para cada categorà ­a de peticià ³n por razà ³n de familia. Pero como el nà ºmero de solicitudes que se presentan anualmente es superior al nà ºmero de tarjetas de residencia disponibles esto hace que se produzca aà ±o tras aà ±o una acumulacià ³n de casos. Y se resuelven por estricto orden de presentacià ³n de la solicitud para cada categorà ­a. Y aquà ­ es donde entra en juego la fecha de prioridad. Cà ³mo se sabe si tienes que seguir esperando o si ya hay una visa disponible para ti Tienes que saber tres cosas: tu fecha de prioridad. Puedes verla en el NOA2tu paà ­s de nacimiento. Y si es Mà ©xico, China, India o Filipinas ver si te puede aplicar un cambio de paà ­s (alternative chargeability)tu categorà ­a Las categorà ­as son estas: cuando el que pide a un familiar es un ciudadano americano: Categorà ­a F1, cuando el beneficiario es un hijo del ciudadano y reà ºne estos dos requisitos: es mayor de 21 aà ±os y est soltero o es viudo o divorciado.Categorà ­a F3, cuando el aplicante es un hijo de un estadounidense y est casado. No importa la edad.Categorà ­a F4, cuando la tarjeta de residencia se solicita para un hermano de un ciudadano. Estos son 10 pasos para este tipo de solicitud, que da una idea clara de quà © se hace en cada momento y de dà ³nde se producen las demoras. Cuando el que pide la tarjeta de residencia para un familiar es un residente permanente legal: Categorà ­a F2A, cuando el beneficiario es el marido o la mujer de un residente o un hijo menor de 21 aà ±os que est soltero.Categorà ­a F2B, cuando se solicita para un hijo soltero del residente permanente que tiene ms de 21 aà ±os. En este caso debe estar soltero, viudo o divorciado. En otras palabras, los residentes permanentes no pueden solicitar una tarjeta de residencia para los hijos casados. Una vez que sabes esos tres datos debes hacer los siguiente: Cada mes, a partir del dà ­a 8 aproximadamente, el Departamento de Estado publica en el Boletà ­n de Visas las fechas de corte (cut-off) para cada categorà ­a de visas de inmigrante para el mes siguiente.   Entonces, lo que tienes que hacer es buscar tu categorà ­a (f1, f2a, f2b, f3 o f4) y mirar la columna de Mà ©xico, si has nacido allà ­, o la del resto del mundo, si has nacido en otro paà ­s de Latinoamà ©rica o en Espaà ±a (o en otro paà ­s que no sea China, India o Filipinas). Y vers una fecha (escrita a la americana, primero el mes, luego el dà ­a y luego el aà ±o). Eso quiere decir que las peticiones en esa categorà ­a con fecha de prioridad anterior a ese dà ­a tienen ya visa de inmigrante disponible. En otras palabras, toda la tramitacià ³n se acerca a su fin, aunque todavà ­a no se ha completado. Si ests fuera de Estados Unidos, quiere decir que el consulado tiene a su disposicià ³n un nà ºmero para la visa de inmigrante. Y si ests ya en el paà ­s, que el CIS tiene un nà ºmero para proceder a tramitar el ajuste de estatus. Pero si tu fecha de prioridad es posterior al dà ­a de corte que aparece en el boletà ­n de visas, eso quiere decir que tendrs que seguir esperando. Retrocesià ³n Si todos los meses consultas el boletà ­n de visas es posible que un dà ­a te lleves un buen susto al ver que las fechas de corte en vez de ir adelantando, den un salto hacia atrs . Esto es lo que se conoce como retrocesià ³n, cuando por la razà ³n que sea no hay visas de inmigrante disponibles para una categorà ­a en concreto o incluso para un paà ­s dentro de una categorà ­a. Suele darse cuando el aà ±o fiscal se acerca a su fin. A tener en cuenta La fecha de corte que aparece en el boletà ­n de visas quiere decir cunto han estado esperando las personas que han hecho su peticià ³n en determinada categorà ­a. Pero si ahora presentas tà º una peticià ³n, no quiere decir que ese vaya a ser tu tiempo de espera. Puede ser mayor o menor. Pero en todo caso te da una idea de lo lento que funciona el sistema. Y aquà ­ se puede ver cunto se demora todo tipo de trmite migratorio, desde lo que tardan las residencias a presentarse en Corte, solicitud de visas u otro tipo de peticiones. Para evitar repeticiones a la hora de escribir el artà ­culo, se utilizan las palabras ciudadano, hijos, trabajadores, etc en sentido genà ©rico, incluyendo tanto al hombre como a la mujer. Es decir, cuando se habla de un hijo de un ciudadano hay que entender que tambià ©n se contempla el caso de la hija de un ciudadano o los hijos de una ciudadana. Y asà ­ en todos los supuestos. Consejo y dà ³nde encontrar informacià ³n Toma una test para verificar que tienes los conocimientos bsicos  sobre cà ³mo obtener y conservar la tarjeta de residencia. Es difà ­cil conseguirla. No corras el riesgo de que te la cancelen por ignorancia. Finalmente, es importante saber dà ³nde encontrar informacià ³n sobre el caso, saber dà ³nde reportar fraudes o dà ³nde solicitar ayuda.

Mastaba, the Original Pyramids

Mastaba, the Original Pyramids A mastaba is a large rectangular structure that was used as a type of tomb, often for royalty, in Ancient Egypt. Mastabas were relatively low (especially when compared to pyramids), rectangular, flat-roofed, roughly bench shaped burial structures that were created and utilized for the pre-Dynastic pharaohs or nobility of Ancient Egypt. They had distinct sloping sides and were typically made of mud bricks or stones. The mastabas themselves served as visible monuments for the prominent Egyptian nobility that they housed, although the actual burial chambers for the mummified corpses were underground and were not visible to the public from the outside of the structure. Step Pyramid Technically, mastabas preceded the original pyramid. In fact, pyramids developed directly from mastabas, as the first pyramid was actually a type of step pyramid, which was constructed by stacking one mastaba directly on top of a slightly larger one. This process was repeated several times in order to create the initial pyramid. The original step pyramid was designed by Imhotepin the third millennium BC. The sloping sides of traditional pyramids were adopted directly from mastabas, although the flat roof typical of mastabas was replaced by a pointed roof in pyramids. The common flat-sided, pointed pyramid also developed directly from the mastabas. Such pyramids were created by modifying the step pyramid by filling in the uneven sides of the pyramids with stones and lime in order to create the flat, even outward appearance. This eliminated the stair-like appearance of step pyramids. Thus, the progression of pyramids went from the mastabas to the step pyramids to the bent pyramids (which was an in-between form of the step pyramid and the triangular shaped pyramids), and then finally the triangle shaped pyramids, like those seen at Giza. Usage Eventually, during the Old Kingdom in Egypt, Egyptian royalty such as kings stopped being buried in mastabas, and began being buried in more modern, and more aesthetically pleasing, pyramids. Egyptians of non-royal background continued to be buried in mastabas. From the Encyclopedia Britannica: â€Å"Old Kingdom mastabas were used chiefly for non-royal burials. In nonroyal tombs, a chapel was provided that included a formal tablet or stela on which the deceased was shown seated at a table of offerings. The earliest examples are simple and architecturally undemanding; later a suitable room, the tomb-chapel, was provided for the stela (now incorporated in a false door) in the tomb superstructure. Storage chambers were stocked with food and equipment, and walls were often decorated with scenes showing the deceased’s expected daily activities. What had earlier been a niche on the side grew into a chapel with an offering table and a false door through which the spirit of the deceased could leave and enter the burial chamber.†

Community Analysis for Sedgefield Elementary School Essay

Community Analysis for Sedgefield Elementary School - Essay Example There is a public library within the vicinity but mathematically and logically speaking, most of the students could not afford to be they're considering the accessibility of the people who are within the area (The distance, the availability of time, availability of materials that are to be used). In the school's case, it has limited resources for the students to enjoy the privilege of having different study materials. It lacks resources that are essential for the need of information in their respective subjects. Therefore a need for more learning materials particularly books and library for the students to enjoy their studies. Due to limited resources, the students are deprived of having a quality education, which is needed by the students. Primarily, the need of literacy program for the students is at bay so the problem for them to read and write is a major concern in order for the students to have at least a capital for them to ascend into the next level of education. So the need for a library is evident. To analyze the library that is present in the vicinity in this small community in Charlotte particularly the Sedge field media center, it ca

The method of texts will articulate in the sense of automatic machines that send constant messages. These will send the most vital messages of the campaign. It will cover the party and the campaign’s slogan. Additionally, it would entail Obama’s principal message or agenda. The other form would entail sending of message that the campaign situation arouses (Harfoush 117). In this strategy, the same would entail responding to queries and comments from the public. Such comments would have to utilize youth-friendly word play. It is vital to note of various requirements to texts. It would involve a study, of use of texts, by youths. The constant messages would have to put up with the colloquial orientation of youth’s language. Since the youths would need an engagement with the campaign, it would be vital that the social media section provide polling and breaking news to the youth population. In addition, the social media section will design applications that enable networking sites in phones. In close relation to the same, it will collaborate with the applications’ companies in availing free systems for phones. In this sense, youths would be able to access videos, of Obama’s campaigns, in other areas. The mobile phones’ applications would be vital in attaining contact information. The applications are vital in locating voter’s centers. Such a target enables tailoring of campaigns in order that it fits the same.

War Through the Media - Essay Example The writer pays much of his attention to the problem of information gaps. The question †what would happen if the Axis powers won the war?†(p. 51) illustrated the fear that people felt. So newspapers used this state of fear and unknowing in order to control the emotional state of the public. Also because of economic competition that existed then between newspapers, every of them tried to outdo the opponent. This caused that truth in headlines disappeared in the content. â€Å"The nation’s newspapers published according to the dictates of their own consciences and interests and printed what they wanted to print, attacked who they wanted to attack, and reported with accuracy or distortion—that is, they acted like a free press†.The government had to find a solution to this problem, so it had to control the information. So the only way out was to form an agency devoted to propaganda. There were several of them only the Office of War Information (OWI), esta blished by President Roosevelt on June 13, 1942, continued its existence. Its mission was to inform public of happening abroad and to counteract enemy propaganda. Jordan Braverman give the definition of the OWI`s objectives, he says that the goals of the OWI were to record, clear, and approve all proposed radio and motion picture programs that federal agencies sponsored and to serve as a contact for the radio broadcasting and motion picture industries in their relationships with federal departments and agencies and concerning these governmental programs†¦Ã¢â‚¬ ¦The OWI was to form

Queen Rania of Jordan: Leadership Case Study

Queen Rania of Jordan: Leadership Case Study Introduction: Queen Rania Queen Rania of Jordan is one of the most influential personalities of the Middle East. She has been called as the New Face of Islamic feminism in the recent world i.e. 21st century. This graduate in business administration, a former banker and a mother of four works tirelessly to improve the conditions of weaker sections of her country and to improve the image of her country on the world stage. She claims to represent the large segment of Arab women, sharing their hopes and aspirations with their face. PERSONAL LIFE: Early Life: As far as her family background is concerned, Queen Rania does not belong to a royal lineage and formerly was Rahia al Yasin. The origin of family is from West Bank of River Jordan. It was previously a part of Palestine that has been annexed by Jordan after 1948 Arab Israeli Conflict and again taken by Israel in the year 1967.Today it is a disputed area as West Bank territories central to the Israeli Palestinian conflict. Because of the continuous instability Rania father, a partition (doctor of childrens), settled in Kuwait in early 60s and became a prosperous man. Childhood and Education: Rania was born on August 31st, 1970 in Kuwait city. She did her early education at a private school New English School After completing her early education in Kuwait, Rania graduated in Business administration from American University in Cairo in 1991. About her childhood experience she writes There was a very large expatriate community in Kuwait. My classroom had child from many different Nationalities. So I grew up with people of Europe, the United States Africa, and the Fareast. These interactions make me realize how alike we are that makes us similar much more Career: After her graduation from American University Rania could not return to Kuwait because it was occupied by Iraqis forces under Saddan Hussain region and the family had to flee to Jordan. Rania follow her family to Jordan Capital Amman and joined City bank there and then served for a short period at the local office of Apple Computer. Here her business contracts brought her a dinner invitation by Prince Abdullah, who was serving military at that time, happen to be present in that party and came in contact with her. Family Life: Rania began her life with her husband Prince Abdullah in 1993 and blessed by four children vs. Prince Hussain (who was named in honor of his grandfather), king Hussain of Jordan, princess Iman and princess Salma and the fourth one is Prince Hashem. King Hussain, the then ruler of Jordan and father of prince Abdullah was fighting with cancer and passed away in 1999.Just before his demise he has chosen Prince Abdullah as his designated heir. RANIA AS A QUEEN: Although king Abdullah ascended on 7th February 1999, Rania had to wait up to march 22 1999, when her husband proclaimed her Queen. Social Life or HM The Queen Rania of Jordan has been declared 76th in the list of 100 most powerful women of world nearly 600,000 people follow her on twitter. She significant strides in promoting East West dialogue by leading a series of files in you tube that explored shared misdeal heritage. Hence she was awarded the first ever Visionary Award by you tube work of H.M. The queen Rania can be divided into the following heads: Domestic Agenda : Her majesty has so many activities on her domestic agenda which includes : A) Madra Sati (My School) This program is the brain child of the Queen Rania, which she launched in April 2008.It, is a public private initiative with an aim to refresh 500 of Jordans public schools over a period of 500 years. She also launched Queen Rania Award for excellence in Education with awards to principals in April 2009. B) H.N the Queen Rania established the first interactive children museum of Jordan. It was established in May 2007. Queen Rania is also chairperson of the royal health Awareness society. This is guide for health for the citizen of Jordan. Queen Rainia recognized three factors to build happy families and healthy homes via Expertise and Energy of Staff at RHAS Ideas and Enthusiasm of Students. Commitments of Partners. At front of higher education, HM Queen Rania scholarship Programmed was established in partnership with several leading varsities from around the world. These scholarships are given in the field of management and marketing, design, finance, business, psychology, architecture, law etc. The standard of scholarships is high and these are given only to most outstanding achievers. These scholarships are given to create a more innovative and dynamic workforce with an eye to fill the existing knowledge gap in for domain labor market which aims at more sustainable socioeconomic model. COMMUNITY EMPOWERMENT It is a nonprofit organization started in Amman to empower society, especially women and children. It is aimed to improve the quality of life and to secure a better future to all for domain through a sustainable socioeconomically and cultural program. It has a weaving project named Bani Hamida weaving project, which promotes Bedouins handicrafts and improve economic and social well being of Bedouins handicrafts and improve economic and social well being of Bedouins women and children. Wadi Al Rayan project is another project hosted by Jordan River Foundation. A group 165 women is engaged in this project in making baskets mats, and furniture from local banana leaves and cattail reeds. SUSTAINABILITY: Queen Rania actively supports the development of sustainable tourism in Jordan through Royal Society for Conservation of Nature (RSCN).RSCN is a non profit, non government organization. It is supported by institutions and individual donation. It is supported by bird life international, world conservation Union (IUCN); later it becomes the largest democratic conservation agency in the world. RSCN was instrumental in establishment of IUCN which covers west Asia.RSCN and IUCN are partners in implementing Jordan Rift valley project and co financing part of this project through direct technical support. International fund for animal welfare (IFAW) also cooperates with RSCN with an aim to enhance biodiversity protection in Jordan. Queen Rania has supported the partnership between Ministry of tourism and Antiquities with WHA (World Heritage Alliance for Sustainable Tourism) YOUTH PROGRAMME She is a strong supporter of junior achievement of world wide. The later is a nonprofit youth organization founded in the year 1919 by Horace Moses. This is the worlds largest and nonprofit organization dedicated to teach the students about entrepreneurism, workforce management and financial activities. GLOBAL AGENDA Human Rights for Women Is a serious practice of killing women, who are found, engaged in extra mental of fairs? Usually it is done by the male members of the family. The telegraph writes about Queen Rania in following words (3rd Dec 2011).Queen Rania, who regularly appears without head scarf, let alone hi job, has given her quiet support to womens rights group who wants to change laws amounting to legal impurity for men involved in honor killing. Queen Rania is supported by Islamic scholars like Sheikh Hamza by insisting that Islamic law or Sharia does not support honor killing is nothing to do with Islam. B). GLOBAL LEADERSHIP The world economic forum is an independent international Organization committed to improving the state of world by engaging business, political, academic and other leaders of society to shape global, regional and industry agenda. H.M Queen Rania is also the chairperson for the nomination of young global leader at WEF. She was the only serving member from Arab world when she attended her first weekly at WEF in 2003. In Nov 2000, Queen Rania was invited to join the global leadership initiative of United Nations Children Fund in recognition of her concern to the cause of children and youth. Vaccine Fund is non-profit International Organization which harnesses resources to seek to provide vaccination of children in the countries of world. In early 2002, the board of Directors of International Youth Foundation has appointed Queen Rania as its member. This foundation is based in BALTIMORE in USA and helps young people to learn basic life skills, education and training. They need to succeed.

That is why she is a fit role model for any Jordanian youth in his/her future carrier. (Queen Raina of Jordan) LEADERSHIP REQUIRED BY UAE Before discussing the leadership required by UAE we must explore various theories of leadership. Leadership is a process of social influence in which one person can enlist the aid and support of others in order to achieve a common goal. It must emphasized that a leader may or may not have a formal authority. There are eight types of major leadership theories prevailing in Contemporary world i.e. 1.Great Man Theories: These theories assume that the great man are borne and not made. These theories presume that leadership is inherited. These types of theories are predominately needed by military advantages and expeditions and in situation of crisis. 2. Trait Theories: These are the modifications of great man theories which presume that certain trait inheritance are required for a person to develop. These theories identify certain common characters in behavior of leaders. 3. Contingency Theory: It describes many variables for leadership to develop. As per this, any different type of leadership are required in different situations. Success is a result of interaction of different variables including the leadership style, qualities of followers and components of situation. 4. Situational Theories: These theories propose the choice of best action in a particular situation. This type of leadership is more appropriate for decision making. 5. Behavior Theories: These theories believe that great leaders are not born but are made. They are based on the action of leader in a particular situation and not on her mental abilities. According to these theories people can learn to become leader through training and education. 6. Participative Theories: Such leaders encourage participation and contribution from their followers and involve them in decision making process. 7. Management Theories: Management or transactional theories take in account the role of Supervision and group performance. As a matter of fact these are the blend of above discussed theories. This type of leadership depends on the reward and Punishment. Phenomenon is supposed to be best suited for business situations. 8. Relationship theories or Transformational Theories: These are based on the mutual understanding and relation bonding between leaders and followers. These leaders motivated inspire like a mentor i.e. they bring up the potential of individuals. Such leaders usually have high ethical and moral standards. Regarding UAE, a blend of almost all the theories except the first one(as there is no crisis or military expedition) are required to meet the challenges of business, social and cultural reforms, education requirement and health aspects. It must be realized that in UAE, the business management deals with the cultural diversity with many nationalities, ethical and cultural groups coming together to achieve a common goal. Moreover today is the era of virtual organization i.e. mostly the organizations are operating via electronic means and there is no face to face interaction of parties involved in the business. Online business is the word coined to denote such business outsourcing is the backbone of such organization along with the telecommunication. So, two different organization may enter into contract involve into exchange of services and payments without community in close contact with other. This may be called as Virtual Organization. This is to emphasize that leadership of these o f organization require a high degree of Managerial Capabilities especially with the phenomenon of globalization of market place i.e. the Integration of National Economic into the International ones through trade, foreign Direct Investment, Capital Flows, Migration Communication and transportation. This results into various nationalities etc to come on a common platform. The economy of UAE is mainly a business based one apart from being oil based. HSBC trade confidence index ranks 2nd in world behind India. So in the last it can be concluded that a leadership with strong managerial capabilities is the most suited one for UAE. (Queen Raina) HANDLING THE MULTICULTURAL WORKFORCE Multicultural Workforce refers to a non power of varying social, cultural, racing and ability characteristics. It is also denoted as diversified workforce. The main challenges is handling a diversified or multicultural workforce, is to accommodate the life style, ethical values, work style and need of these different group without compromising with the common goal on operations of an organization. A business leader can use the diverse characteristics of a multicultural human wealth to a strategic advantage with creativity. A multicultural workforce makes a good business opportunity. Organizations with corporate environment are now facing a difficult question i.e. Can Diversity be best treated by equal treatment or differential treatment? Although the advocated of anti discrimination may argue that it is inhuman or illegal in certain countries but some managers may argue that this premises ignores the fundamental of diversity i.e. the different behavior of the people from different nationality or Ethnic groups in different condition. For example an employee from the Far East may be happy if he is asked to work for more hours and paid for that extra period of time. On the other hand, the same person simply refused to work more if he will not be paid. But at the same time treating work force in a differential way may result into resentment and can erode morale. Such difficulties are enhanced when weaker sections of society like women are involved. However such difficulties may be addressed by simple measures like: Having warm attitude towards all employees regardless of their nationality, religion, or ethnical origin. This practice must exist at top managerial level without prejudice. Multi Cultural Dialogue: The man power of an organization diversified origins should be asked for a directed inter cultural dialogue. This means setting up a discussion group by top management with participants from different origins, nationality, ethnicity, or social backgrounds. This type of dialogues will result into exchange of cultural knowledge and the participants will learn more about why their co workers believe and act the way they do. This leads to a greater tolerance. Cross Cultural Training Seminars: holding of cross cultural training seminar is a positive approach to deal with a multiethnic workforce. Experts from multiethnic elations are to be involved in this type of approach to teach the employees to bridge the cultural gap between them. Such type of seminars may include value origin, world view and tolerance development. Core Values of Employees: This is perhaps the most important action that top management can have to understand the behavior of persons from different ethnic groups in their organization. This is greatly facilitated by presence of Internet and the Information about different cultures is just a click away. So it is clear that a multicultural workforce is not a challenge rather an opportunity creation and approach management in an organization. DEVELOPMENT OF EFFECTIVE LEADERSHIP The effective leadership can impart great deal of motivation in his followers resulting into a high level of achievements. This must be realized that self learning is the most important tool to develop an effective leadership. As the leader is the mentor of his followers it is important for him to acquire more and more knowledge, skill and education to pass it to them. To develop a good leadership one must explain: A basic sense of the System of organization, its function and role and how they are integrated to achieve the goal of the organization. Functions of management, Leadership are one of them and their integration in the organization. A continuous training of the management methodology is a must in this regard. Different traits, models and theories of leadership including different domains of it. As each domain requires different approach and competencies in order to lead that domain a continuous coaching of the leader is a must to develop such qualities. Finally how one can develop his abilities in leadership in a formal or informal way Developing Effective Leaders: Developing leaders to be more effective comes under the domain of leadership development program, which refers to any activity undertaken with a view to enhance the quality and effectiveness of leadership in an organization. These activities may range from management program like MBA, Business diplomas or any post graduate courses offer by companies owned universities, action learning i.e. an Education process of learning by ones own action and experiences in order to improve performance. There may be high rope courses, which are challenging outdoor personal development and team building activity. Such programs are usually constructed in trees or made of utility poles and require strict safety measures to be followed. However there is a non census to be followed about their utility in developing effective leadership. It is also to be emphasized at this level that leaders are rather developed internally rather than recruited. Future Leadership Requirement Model: A leader with focus more on Strategic issues and organizational changes, rather than current operational problem. Apart from leadership competence, a future leadership model will require to take into consideration of issues like work/life balance, potential advances in globalization, technology and return of Investment and increasing interest in the integrity and character of leaders and new way of thinking about leadership.
