(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.

Bell Hooks Essays -- essays research papers

Is Education Equal?   Ã‚  Ã‚  Ã‚  Ã‚  The United States provides our society with the undeniable right to learn. The right to higher education is not limited to the middle and upper classes; it allows the less privileged, minorities, as well as both sexes, to receive an equal education. Two arguments which present interesting views on higher education are bell hook’s “Keeping Close to Home'; and Adrienne Rich’s “What Does a Woman Need to Know?'; Hooks views higher education with a concern for the underprivileged, whereas Rich views it with a concern for women. Of the two works, I personally do not agree with Rich’s argument.   Ã‚  Ã‚  Ã‚  Ã‚  Bell hooks views higher education to be a time in which we find ourselves and learn more about who we are. This concept remains difficult on the underprivileged because they do not want to be known for their background. They see themselves as less privileged, and therefore want to keep this hidden from their new society. These students face many obstacles in their lives; college presents a whole new and much larger challenge. The transition is also hard on them. They want to fit in and hide their past, but at the same time, they do not want to lose sight of their upbringings. Hooks felt that she was an outsider in college, because she herself came from an underprivileged background, while most of her peers came from privileged backgrounds. Hooks states, ̶...

For small businesses, does the reality of using social and new media in marketing live up to the promise? A qualitative study amongst business owners in the UK

Abstract The area of emerging technology and marketing has become an topic of increased debate as the potential to reach more consumers and provide real savings for small business is created. This study assesses the impact that emerging communication technology has had on the marketing efforts of small businesses in the UK. 1 Introduction1.1 Research TopicThis study assesses the impact that emerging communication technology has on the marketing efforts of small businesses in the UK. In order to properly evaluate each element, this study uses a survey given to several owners and operators in the UK coupled with a case study centred on the small business in the London area to provide evidence for industry and cultural assessment. These factors will be used to illustrate detailed components of operation and implementation for small businesses in the UK. With a focus for identifying distinct themes in the survey results, this research seeks to combine working experience with social expectation to provide an illustration of potential opportunity.1.2 Objectives1) Assess technological impact on small business 2) Evaluate how communication technology provides opportunities for growth.1.3 Research questions1) What are the challenges faced by small business in marketing? 2) Can improved consumer outreach improve revenue? 3) Does new technology offer a competitive edge for small business? 2 Review of Literature2.1 Small Business ChallengesMarketing is an essential element of small business strategy (Safko et al, 2009). With a clear need to remain in the consumer eye, marketing has the potential to make or break any small business (Qualman, 2009).2.1.1 Current MethodsCurrent methods of marketing include television, print and word of mouth (Qualman, 2008). Further, any advertising must be local or regional, facing increased cost (Safko et al, 2009).2.1.2. Emerging methodsInternet and communication technology provide social media, online content and increased consumer exposure for small businesses(Berthon et al, 2012; Fischer et al, 2011;Weinberg et al, 2011).

Biology Lab Report Ib Hl Osmosis

Biology Lab Report 2 Investigating the phenomenon of Osmosis in plant tissues: Potato in different concentrations of NaCl Tutor: Maria Tsaousidou By Marina Gkritzioudi Biology Lab Report 2 Investigating the phenomenon of Osmosis in plant tissues: Potato in different concentrations of NaCl Tutor: Maria Tsaousidou By Marina Gkritzioudi Investigating the phenomenon of Osmosis in plant tissues: Potato in different concentrations of NaCl Introduction: Osmosis is the movement of water molecules through a semipermeable membrane from low concentration to high concentration. Research Question:How does the concentration of salt (NaCl) affect the mass of a potato soaked in water (H2O) with different concentrations of NaCl over the course of 30 minutes? Hypothesis: It is expected that the solution with the highest concentration of salt will cause more mass loss to the pieces of potato. The pieces that will be placed in the solution with the lowest concentration of salt will have small weight los s. Finally, the pieces that will be placed in water (NaCl concentration 0) will gain weight. This is expected because of the phenomenon of osmosis which was examined in a previous lab. Variables:Independent: concentration (%) of salt (NaCl) Dependent: mass (g) change Controlled: * shape and material of the beakers * size and weight of the potato pieces * volume of the aqueous solution The beakers need to be of the same size, of the same shape and of the same material, either plastic or glass. The size of the potato pieces needs to be the same in order for the surface to volume ratio to be the same and the initial weight of the pieces should also be the same so that the mass change can be compared. Since this is not always possible, we calculate percentages and make the pieces approximately the same.Lastly, the volume of the water solutions should be the same in all beakers so that the osmotic effect will only depend on the concentration dissolved in the solution. Materials: 5 beaker s sized: 250cm3 (Â ±0. 5cm3) Tap Water Potato Knife Weigh balance (Â ±0. 01g) Salt (NaCl) Watch glass Spatula Timer (Â ±0. 1sec) Volumetric cylinder Procedure: Step 1: Line up the five beakers and with the help of a volumetric cylinder add 100cm3 of water (H2O) in all of them. Step 2: Place the watch glass on the weigh balance and after zeroing it, measure four different concentrations of salt by adding it with the spatula.Start by measuring 0. 5% of NaCl, then 1%, then 3%, and finally 5% and add each one in a different beaker. Step 3: Stir the solutions using the spatula in order for the salt to dissolve. Step 4: Take a potato and after peeling it with the knife, cut it into 10 same size small pieces. Step 5: Measure each one of the 10 pieces and in order to equalize their mass chop, or scrape off some of the piece if needed. Step 6: Record the initial mass of the potato pieces and place 2 potatoes in each beaker. Step 7: After 15min take each of the pieces out of the beakers an d measure its weight and record it.Step 8: Repeat Step 7 after 30min and after 35min in order to get the rate at which the mass changes. Data Collection: Table 1: Mass measurements of the potato pieces in solutions with different NaCl concentrations over the course of 35min | Time in min| Mass(g)(Â ±0. 01) in 0. 5% NaCl concentration| Mass(g)(Â ±0. 01) in 1% NaCl concentration| Mass(g)(Â ±0. 01) in 3% NaCl concentration| Mass(g)(Â ±0. 01) in 5% NaCl concentration | Mass(g)(Â ±0. 01) in 0% NaCl concentration| | Trial 1| Trial 2| Trial 1| Trial 2| Trial 1| Trial 2| Trial 1| Trial 2| Trial 1| Trial 2| 0| 1. 76| 1. 76| 1. 76| 1. 76| 1. 76| 1. 6| 1. 76| 1. 76| 1. 76| 1. 76| 15| 1. 80| 1. 80| 1. 63| 1. 63| 1. 57| 1. 57| 1. 58| 1. 58| 1. 95| 1. 95| 30| 1. 80| 1. 80| 1. 54| 1. 54| 1. 50| 1. 50| 1. 51| 1. 51| 1. 97| 1. 97| 35| 1. 79| 1. 79| 1. 52| 1. 45| 1. 49| 1. 42| 1. 48| 1. 45| 1. 98| 1. 98| Data Processing: In Table 2 the average mass of the measurements of the two trials from Tabl e 1 over the course of 35min is shown. The information in the table was a result of adding the measurements from both of the trials, at a specific time, and dividing this sum by two. For example, in the 5mol dm-3 NaCl concentration the mass (g) after 35min was 1. 8g in the 1st trial and 1. 45g in the 2nd trial (see Table 1). The average of these two measurements for the time of 35min, in concentration 0. 5mol dm-3 NaCl, is found by adding them and dividing their sum by two: (1. 48+1. 45)? 2=1. 465, rounded to 1. 47g. Table 2: The average mass measurements of the potato pieces in solutions with different NaCl concentrations over the course of 35min| Time in min| Mass(g)(Â ±0. 01) in 0. 5%3 NaCl concentration| Mass(g)(Â ±0. 01) in 1% NaCl concentration| Mass(g)(Â ±0. 01) in 3% NaCl concentration| Mass(g)(Â ±0. 01) in 5% NaCl concentration | Mass(g)(Â ±0. 1) in 0% NaCl concentration| 0| 1. 76| 1. 76| 1. 76| 1. 76| 1. 76| 15| 1. 80| 1. 63| 1. 57| 1. 58| 1. 95| 30| 1. 80| 1. 54| 1. 50| 1. 51| 1. 97| 35| 1. 79| 1. 49| 1. 46| 1. 47| 1. 98| In Table 3 the average mass change of the measurements over the course of 35min is shown. This is calculated by subtracting the initial measurement of the average mass of the pieces of potato (measurements of 0min shown in Table 2), which are submerged in different solutions with different salt concentrations, from the final measurement of the mass of potato present in the same concentration (measurements of 35min shown in Table 2).For example, the average mass change over the course of 35min in NaCl concentration of 05mol dm-3 is found by subtracting the first average measurement of the mass, 1. 79g, from the final average mass, 1. 76g: 1. 79-1. 76=0. 03g. Table 3: Average potato mass change in each solution over the course of 35 minutes| | Mass(g)(Â ±0. 01) in 0. 5% NaCl concentration| Mass(g)(Â ±0. 01) in 1% NaCl concentration| Mass(g)(Â ±0. 01) in 3% NaCl concentration| Mass(g)(Â ±0. 01) in 5% NaCl concentration | Mass (g)(Â ±0. 01) in 0% NaCl concentration| Mass (g) change (Â ±0. 01)| 0. 03| -0. 27| -0. 30| -0. 29| 0. 22|When the mass change is a positive number, this means that the mass of the specimen, the potato piece, increased from the initial mass. On the contrary, when the mass change is a negative number, this means that the mass decreased from the initial mass that was first measured before it was submerged in the solution. In Table 4 the rate at which the mass increases or decreases in the five different solutions is shown. This is calculated by dividing the absolute average mass change of each solution (shown in Table 3) and dividing it by the maximum time used in the experiment, which is 35min.For example, the rate at which the mass drops or increases in the 0. 5mol dm-3 NaCl concentration solution is shown by taking |0. 03| (Table 3) and dividing it by 35min: |0. 03|? 35=8. 6*10-4g/min. Table 4: Rate at which the mass increases or decreases. | | In 0. 5% NaCl concentration solution | In 1% NaCl concentration solution| In 3% NaCl concentration solution| In 5% NaCl concentration solution| In 0% NaCl concentration solution| Average mass (g)/time (min)| 8. 57*10-4| 7. 71*10-3| 8. 57*10-3| 8. 28*10-3| 6. 28*10-3| In Table 5 the percentage% mass change is shown.This is calculated by subtracting the average initial mass measurement from the average final one, dividing it by the average initial mass and multiplying it by 100. For example, the percentage% mass change in the 0. 5mol dm-3 NaCl concentration solution is calculated like this: [(1. 79-1. 76)/1. 76]*100=1. 70%. Table 5: Percentage% mass change| | Mass(g)(Â ±0. 01) in 0. 5% NaCl concentration| Mass(g)(Â ±0. 01) in 1% NaCl concentration| Mass(g)(Â ±0. 01) in 3% NaCl concentration| Mass(g)(Â ±0. 01) in 5% NaCl concentration | Mass(g)(Â ±0. 01) in 0% NaCl concentration| Percentage%Mass change| 1. 0| -15. 34| -17. 04| -16. 47| 12. 5| Graph 1: Mass changes of potato pieces bathed in NaCl solutions Graph 2: Ra te at which the mass in each solution increases or decreases Conclusion: The data collected confirmed the hypothesis that that the solute with the highest concentration of salt will cause more mass loss to the pieces of potato, the pieces that will be placed in the solute with the lowest concentration of salt will have small weight loss, and the pieces that will be placed in water (NaCl concentration 0) will gain weight thus increasing in mass.After observing the changes in the mass of the potato pieces we can tell that the higher the concentration of salt in the water, the more the mass of plants will decrease because of osmosis. The lower the concentration of salt in water, the more the mass of the plants will increase or just decrease but not dramatically. If we submerge a plant in water with no NaCl dissolved in it, the mass of the plant will increase, because water molecules will move from the low concentration solute to the high, thus entering the plant tissue and increasing i ts mass and weight.Also, time wise, the more the plant specimen soaks in the solutions the more its mass will relatively increase or decrease. Lastly, from the first graph it can be estimated that at concentration 4. 2% the potato in the NaCl solution will reach equilibrium, thus the concentration will be the same inside and outside of the potato. Limitations: There are some limitations to this experiment that prevent the results from being perfect. First of all there was not enough time to repeat the experiment and because the lab was crowded there was no time to chop more han two pieces of potato for each beaker so only two trials were performed instead of three or five. Secondly, the sizes the potatoes were chopped in were not exactly the same because more attention was given to having the same mass and thus neglecting the size which leads to different surface to volume ratio and affects the results. Thirdly, the timer that was used was the classroom clock and therefore the time at which the pieces or potato were measured were not very accurate.Improvements: In order to improve the results of this experiment, it is necessary that some changes be made. Firstly, a tool should be found that will allow potato pieces to be chopped in the same size so that the surface to volume ratio will be the same and not change, thus affecting the results. A proper timer should be used to count the time intervals. Lastly, more repetitions, at least 3, need to be made so that the results are more precise.
