Nutritional Assessment Concerns in Competitive athletes Population Research Paper

Nutritional Assessment Concerns in Competitive athletes Population - Research Paper Example Another athlete concern is which best food supplements to take. The food supplements contain different quantities of vitamins, minerals, and other food needs. The article, Supplement Use in Sports: Is There a Potentially Dangerous Incongruence Between Rationale and Practice? ((Petroczi & Naughton, 2007), focuses on the dietary supplements to enhance athletes’ sports performance. The research centered on the athletes’ improved sports performance by enhancing their dietary intake. The researches delved into the analyzing the evident patterns when comparing the intake and rationale in terms of the athletes’ dietary supplements. Supplements include vitamins, minerals, herbal remedies, herbal products, and amino acids. The research also shows that the overdose of food supplements have toxic side effects on the athletes. In addition, the article, Comparison of pre-worked nitric oxide stimulating dietary supplements on skeletal muscle oxygen saturation, blood nitrate/nitrite, lipid peroxidation, and upper body exercise performance in Resistance Trained Men (Canale et al., 2010), focuses on research on three different pre-workout food supplements. The research focused on the effect of the food supplements of the athletes’ skeletal muscle oxygen saturation, blood nitrate/nitrite, lactate, malondialdehyde, and exercise outcomes. The research conclusions state only GlycoCarn supplement offers practical boosting benefits to the athletes. Another athlete concern is the effect of food supplements on enhancing the elderly athletes’ sports performance. In response, the article Arginine and Antioxidant Supplement on Performance in Elderly Male Cyclists: A Randomized Controlled Trial (Chen et al, 2010) focused on food supplements’ capacity to enhance sports performance, answering this concern. The research focused on the

Impregnation of Calcium Chloride on Activated Carbon Surface

Impregnation of Calcium Chloride on Activated Carbon Surface This performance of solar refrigerator is based on some key parameters like ammonia carrying capacity, adsorption rate, heat transfer mechanism, stability etc., this paper presents the stepwise detailed preparation of consolidated calcium chloride impregnated on the surface on activated carbon. Ammonia was charged into the tube containing blocks under high pressure of 7 bars was applied during initial charging session and total adsorption was noticed in 25 minutes and the process was repeated. The total amount of ammonia adsorbed was 2.4 kg and was capable of taking more ammonia. Agglomeration effect was totally avoided by the even distribution of calcium chloride on the surface of activated carbon. Carbon was activated at elevated temperature of 700 C for optimum properties. 1. Introduction Solar refrigeration and heat pump are machines that work on wide range of temperature, especially when ammoniates or ammonia derivatives are involved as sorbents then temperature can range from -50oC to 300oC [1]. Furthermore it is environmentally benign and it does not contribute to global warming or ozone layer depletion. They do not usually utilize CFCs or HCFCs as refrigerants. This type of refrigeration is based on the phenomena of adsorption which is a surface phenomenon in which one is adsorbent and second is adsorbate or refrigerant. Two main types of adsorbents are used, one is physical adsorbent like activated carbon in which the adsorbate/refrigerant is adsorbed on its surface by week Vander Waals forces. This process  is dependent on the surface area of adsorbent. It is said that one gram of activated carbon has an area equal to the area of a tennis yard. The mass of adsorbate/refrigerant adsorbed in this process is very less because of weak Vander Waal forces. The second type of adsorbent is chemical adsorbent like Calcium chloride. When it comes to sorption capacity we use chemical adsorbents. The mass of refrigerant incorporated here could be as high as 1.05 kg/kg salt [2]. But there are two serious concerns with this, one is granular salts have very low thermal conductivity and second is the agglomeration phenomenon. The salts after some cycle s of adsorption and desorption it undergoes it swells, compacts and agglomerates, which leads to drastic reduction of the surface area and ultimately reduces the adsorption capacity. Wang et al. [3] mixed activated carbon with calcium chloride salt which overcame the phenomenon of agglomeration and observed a constant adsorption capacity. Lu et al. [4] observed specià ¯Ã‚ ¬Ã‚ c cooling power ranging from 111.2 to 865.8 W/kg using adsorption ice maker. Vasiliev et al. [5] used carbon fiber with calcium chloride and reported to have increased heat and mass transfer phenomena and overcome agglomeration. Later Mauran et al. patented a process to make impregnated consolidate blocks of calcium chloride and activated carbon. Han and Lee [6] found the thermal conductivity of different salts impregnated in expanded graphite blocks and measured values close to 50 W m-1 K-1 when the amount of expanded graphite was 70%. Ammonia is used as refrigerant and the process of chemisorption is governed the following two basic equations. 1.  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   CaCl2.2NH3+2NH3  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   CaCl2.4NH3 2.  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   CaCl2.4NH3+4NH3  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   CaCl2.8NH3 This process of impregnation of calcium chloride on the surface of activated carbon not only ensures uniform distribution of calcium chloride on the surface of activated carbon but also avoids agglomeration over many synthesis cycles. Balat and Spinner [7] reported that the texture of expanded graphite favors the mass transfer of the adsorbate/refrigerant which leads to improved kinetics when activated carbon combined with a salt is used in the chemisorption system. Experimental Setup and Results: The following steps were performed during formation of composites blocks of calcium chloride and activated carbon: Heat treatment of calcium chloride and activated carbon, Making solution of water and calcium chloride and mixing it with expanded graphite, Impregnation of calcium chloride in expanded graphite Calcination of hydrated calcium chloride into calcium chloride, Grinding of the dried impregnated mixture of calcium chloride and activated carbon and finally formation of consolidated blocks from powder obtained from grinding. Heat treatment of carbon: In the experiment performed by Wang et al [6] the expanded graphite is heated at the temperature of 300oC. But according to Han et al the temperature of the heat treatment influences the degree of expansion and these authors stressed on the importance of expanded graphite at temperature higher than 600oC to ensure a proper expansion. Han and his co-worker [9] also noted that the graphite expanded at temperatures above 700oC had the lowest densities and at least twice the porosity of expanded graphite treated at 500oC. The expanded graphite used has the chemical composition given in table. The heat treatment of carbon powders was carried out to increase its porosity and to remove the contaminants from the carbon powders. Carbon powders were placed in container and placed in an electric oven at 100oC for 7 hours in order to remove the moisture contents contained in it. 2kg of carbon powders were placed in two separate aluminum vessels in the oven at 100oC for 7 hours. After this it is placed in desiccators to avoid absorption of moisture contents till the start of the second process. In the last step heat the carbon powders obtained from the first step in vacuum at 700oC in a tube furnace for a dwell time of 14 minutes. Procedure: Put small amount of carbon powders in blind stainless steel tube of diameter 1.5 inches and length 15 inches and press them with a rammer so that the tube can hold a maximum amount of carbon powders. After placing the carbon powders in the tube seal the open end of the pipe with wire gauze with †¦Ã¢â‚¬ ¦ mesh and cotton cloth in order to prevent sucking of carbon powder by vacuum pump connected through a plate at the open end, tight the end cap of the tube to avoid infiltration of air into the tube. If air enters the tube in the heating process underway simply oxidation of the powder takes place. Then Place the tube in the tube furnace and connect it with the vacuum pump to remove the air entrapped in the tube and any other residual gases produce during heating of carbon powders. In the experiment by Wang et al. [2] expansion of graphite above 700 C has no significant effect on the reduction of the density of activated carbon also Hans [3] and coworkers shows that carbon expande d at a temperature of 700 C has lowest density and twice the porosity as compared to expansion at 500 C, so the temperature of the furnace is set at 700 oC giving a ramp rate of 10 oC/minute. When the temperature of the furnace reached 700 oC we set the machine at a dwell time of 14 minutes in order for carbon powder to undergo full expansion. After that the furnace was turned off and the tube was allowed to cool down. When the furnace cools down remove the carbon powders from the tube and stored it in a desiccator. The furnace takes one and a half hour to reach 700oC and 2 hours for cooling the tube as a result this process took us a lot of time. About 150 grams of carbon powder were expanded in a single run. This process was repeated until a total mass of 2.4 kilograms of expanded graphite was obtained. Tube used for holding the carbon powder in tube furnace: A tube was designed to hold the carbon powders in the tube furnace. The tube was made of stainless steel which can withstand high temperature of the tube furnace. A metal plate is welded to one end of the pipe to permanently close one side of the pipe and the other end was left open for pouring the powders into the tube. A cap was made to seal the open end of the pipe after filling with the carbon powders. The cap has an extension pipe for connecting the tube with the vacuum pump. A 300 grid mesh was used before the cap and cotton cloth was also applied to avoid the suction of carbon powders into the vacuum pump. The cap itself is made of two metal plates. One plate has a groove of 3 mm depth and a diameter equal to the pipe diameter which holds the tube in place. The two plates were bolted with each other through four nuts and bolts. The specifications of the tube are given below; Total length30 in Diameter of tube1.5 in Volume of tube0.000376m3 Density of carbon450 kg/m3 Mass of carbon0.1693 kg Table.2 dimensions of vacuum tube Heating of calcium chloride: Heat treatment of calcium chlorides was also carried out remove the moisture content and any contaminants in it. 2. Experimental procedure: The following steps are carried out during the heat treatment of the calcium chloride. Since calcium chloride salt is very hygroscopic in nature and it absorb moisture very easily. Put 4kg of calcium chloride salt in stainless steel vessels and covered the mouths of the vessels with aluminum foils. Small holes were made in aluminum foil for the moistures and gases to escape out of the vessels. These vessels were then placed in an oven at a temperature of 100oC for 10 hours to remove the moisture contents out of the calcium chloride salt. After heating calcium chloride salt at 100oC. It is then placed in desiccators to avoid the absorption of moisture by the salt until next step. Preparation of solution of calcium chloride and activated carbon using distilled water: After the heat treatment of calcium chloride and activated carbon 60% salt solution of calcium chloride in distilled water is prepared. 4kg of calcium chloride and about 7 liters of distilled water was used for making solution. Activated carbon is then stirred thoroughly in bottle and poured into the solution of calcium chloride salt and stirred for some time for uniform mixture. Based on the result of Wang et al. [6] best performance is shown when calcium chloride and expanded graphite are mixed in the ratio of 4:1. Figure: 60% solution of calcium chloride and water Figure: mixture of solution of calcium chloride and activated carbon Impregnation of calcium chloride in expanded graphite: The solution is then dried for 10 hour at 110 0C in an electric oven to remove free water and allow Impregnation of calcium chloride in expanded graphite. This figure shows the final shape of uniform mixture of activated carbon and calcium chloride salt when it loses all water in an electric oven. Calcination of hydrated calcium chloride into anhydrous calcium chloride: After impregnation of calcium chloride on the surface of expanded graphite the solution is again heated in an oven at 250oC for 7 hours [] to calcinate the calcium chloride as a result the hydrated calcium chloride become anhydrous. CaCl2.nH2O  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   CaCl2 + nH2O Grinding When the solution is dried and dehydrated in the electric oven the mixture is grinded in the grinding machine to make fine powder of the composite materials. The fine powders are then placed in desiccators in order to avoid the absorption of moistures by the powders until the next process. Die used for making consolidated blocks: In order to compress the obtained the powder above under pressure of 10 MPa using UTM it is placed in the mold shown below. The die consists of a cylindrical tube, a piston, a metal plate at the bottom of cylindrical tube and stainless steel rod. The cylindrical tube, metal plate and piston is made of mild steel. Graining of piston and cylindrical tube is done to make the surface smother so that block would not stuck in it after compression under immense pressure. No binder was used in the compaction of powder into consolidate blocks. Specification of cylinder are given below Thickness of cylindrical tube is 5mm and its height is 152.4 mm. Internal diameter is 50 mm. Specification of piston are given below Height is 15 in Diameter of piston is 49mm The piston having a hole at its center is lengthwise whose inner diameter is 15 mm. Figure: Die for making consolidated blocks of calcium chloride and activated carbon Consolidate blocks Formation: To make hollow cylinder of obtained powder under UTM following steps were followed. The resulted powder (impregnated with calcium chloride) are poured into the cylindrical part of the die through funnel, then a piston is placed on the top and a small load is applied manually to make the powder a bit compressed. The die is fitted in a UTM and pressed under 10MPa of load. [10] Figure: composite blocks of calcium chloride and activated carbon The composite blocks are placed inside the test unit, experiments were performed and test results were analyzed. RESULTS AND CONCLUSIONS: EPERIMENTAL PROCEDURE FOR CHARGING Charging of ammonia required great care because it is very dangerous and can cause blindness and even death when come in contact with human. Therefore during charging great care should be taken and all the safety rules must be followed. Before charging ammonia make sure that entire setup is leak proof and there is no leakage during charging or after charging. Compressor is connected to the generator line and whole system is evacuated from air and its noted that either vacuum is created or not by taking reading through pressure gauges attached to generator line. By performing these entire tests and conforming that no leakage is present the system is passed through the following steps. s.no.Initial pressure before chargingFinal pressure after chargingTime taken until  Ã‚   0 barMass adsorbed 1st run-1 bar6.0 bar25 min600 grams 2nd 0 bar7.0 bar39 min700 grams 3rd 0.4 bar8.0 bar30 min500 grams 4th 0.5 bar10 bar49 min750 grams 1.First of all generator line is heated for 3 hours at 100oC with the vacuum pump connected to remove the gases adsorbed in the adsorbent. This process is called degasing. 2.Secondly the system is evacuated using vacuum pump and it is placed idle for 30 minutes to find out whether any leakage is occurring or not. 3.   After the system is evacuated the compressor along with all plumbing is detached from generator line and ammonia charging hose is placed in place and tight fit is ensured. 4. Then charging line is connected with ammonia cylinder. The valve pipe connecting the ammonia tank and generator line is supplied with a manual valve. Initially the valve is opened slowly to flood the ammonia into the generator line, the pressure inside the generator line starts increasing. As ammonia starts adsorbing inside the pipe the pressured reduces while the manual valve is opened and closed at the succession of the processes. 5. After charging the system is closed using manual value to stop the further flow of ammonia and wait until the pressure in the system reduces due to adsorption of ammonia in the adsorbent material. 6.When the pressure reaches its minimum level the system is charged with ammonia again and wait until the pressure in the generator line decreases. 7.This process is repeated until 2.4kg of ammonia is charged into the system. The experimental data achieved during charging of the system is given in table given The total amount of ammonia charged into the system was about 2.4 kg. The mass of ammonia was find out using digital scale. The generator line is placed on the scale and mass is noted before and after charging. In this way mass of ammonia adsorbed is find out. CONCLUSIONS: The powders were successfully activated using available research facility. Impregnation of calcium chloride on the surface of activated carbon greatly enhances its ammonia carrying capacity and adsorption rate. The phenomena of agglomeration and swelling as depicted by literature survey was completely overcome and heat and mass transfer was efficiently enhanced. Because no binder was used in the blocks so blocks were made under relatively high compression using UTM. References: [1] E.E.

Arctic and Alpine Soils Essay -- Argriculture Research Papers

Arctic and Alpine Soils Proposal (Ant)arctic (high-latitude) and alpine (mountain) areas are affected by relatively similar climates, as latitude and altitude produce similar meteorologic effects. In these geographic regions where temperature is at such a pronounced extreme, climate would seem to be the leading factor of soil development. It is my goal in this research paper to answer the following question: How do the soils of arctic and alpine areas differ? This idea, taken largely from an abstract by Birkeland (1975), will be explored through the comparison of the soils of these two geographic regions, and an analysis of the soil development factors in those environments. Introduction Both high-latitude and high-altitude regions are subject to climates that are dominated by extreme cold for at least part of the year. This extreme characteristic creates within these regions a stark environmental contrast to most other geographic regions of Earth, pairing with climate a different and uncommon set of geomorphologic features on the thin surficial layer of the planet. Dokuchaev (1886 & ca. 1900; and 1899, as quoted by Afanasiev (1927); and Gerasimov (1956), respectively) made progressive early studies in soil science in the Caucausus Mountains and in Arctic Russia and applied a theory that drew an analog between vertical and horizontal zonality. He observed that biota and temperature changed drastically at increasing elevations in much the way that the same characteristics vary with increasing latitude. Dokuchaev then extrapolated that the variation in biota and temperature would also indicate similar changes in soil types, but did so without sufficient observed suppor t.

Report on Cross Cultural Management of Cuba Essay

4 Analysis of Silk Trade in Cuba To a great extent, the silk trade can be influenced by the culture. Before entering into the Cuban market, the company needs to understand the culture and take into account the local market situation. Cross cultural management models can be used to analyze the cultural characteristics in Cuba, for example Geert Hofstede Cultural Dimensions, Fons Trompenaars Cultural Dimensions, and Ednlard T. Hall Cultural Dimensions. In the following, cross cultural models will be used to conduct an assessment of Cuban cultural background and analyze the impact of Cuban culture on the silk trade. Fig 1 Location of Cuba 4.1 Cuban culture under Geert Hofstede Cultural Dimensions Professor Geert Hofstede is an expert in the field of cross cultural management. His study on the cultural dimensions can be used to help define the culture of a country in the world. According to Geert Hofstede Cultural Dimensions, each kind of the culture places different emphasis on five different cultural dimensions, Power Distance (PDI), Individualism versus Collectivism (IDV), Masculinity versus Femininity (MAS), Uncertainty Avoidance (UAI), and Long term orientation (LTO) (Hofstede, 1996). 4.1.1 Power Distance According to the view of Professor Hofstede, power distance deals with the income inequity in a country (Soares et al., 2007). Cuba scores high in the scale of power distance, which means that the members of this country believes that inequities are usual and accepted by all layers of the society, and the leaders of an organization can have a lot of power. The reason can be found in the long history. 4.1.2 Individualism versus Collectivism The dimension individualism is the degree of interdependence a society maintains in its members. In simple words, it deals with whether people’s self-image is defined in terms of I or We. It is known that Cuba is a communist country and it is a collectivist culture. Under such political environment, people work together and share everything. The Cubans believe that all the people are important and cooperation is important in the society. In simple words, collectivism is widely accepted in Cuba. 4.1.3 Masculinity versus Femininity The dimension masculinity deals with what motivates people, wanting to be the best (masculine) or liking what you do (feminine). Under the Cuban culture, people are always more feminine. The dominant values in the society are caring for others and quality of life, rather than the competition, achievement, and success. In addition to this, the Cuban women have played an important role in the society, and women hold nearly 37% of the seats in parliament. The Cuban culture is more feminine. 4.1.4 Uncertainty Avoidance The dimension Uncertainty Avoidance can explain how people deal with the unknown future, some may try to control the future, and some may let it happen (Merkin, 2006). People in the Cuban society belong to the category of high uncertainty avoidance. To a large extent, it is decided by the political environment, the communist society for years can be the reason why Cuban people eliminate unwanted changes in the future. 4.1.5 Long term orientation The long term orientation dimension decides the extent to which the society shows a pragmatic future-oriented view rather than a conventional historical short-term view. In Cuba, people fall more in the conventional short-term view. The society is largely controlled by the government, and people live life day to day with the conventional short-term view, also they have not planned too much for the future. 4.2 Cuban culture under Fons Trompenaars Cultural Dimensions According to the view of Professor Fons, what distinguished people from one culture is where their preferences fall on each of the seven different dimension, including universalism versus particularism, individualism versus communitarianism, specific versus diffuse, neutral versus emotional, achievement versus ascription, sequential time versus synchronous time, and internal direction versus outer direction (Charles and Trompenaars, 1997). The dimension universalism vs. particularism deals with what is more important, rule or relationship. In Cuba, people believe that relationships can be more important, which is largely decided by the political factor. Under the communist society, the whole society is controlled by the leaders of the country, and the society is decided by rule of people, rather than rule of law (Rasha, 2006). Individualism vs. collectivism deals with the degree of interdependence a society maintains in its members. Cuba falls more in a collectivist culture. In addition, the neutral vs. emotional dimension describes the importance of feelings and relationships. Obviously, Cuba, a neutral culture, and people do not easily display their feelings and emotions. The government controls everything, and people dare not display their real feelings (Kang and Mastin (2008). Specific vs. diffuse dimension answers how the people separate the private and working lives. Cuban culture belongs to the specific-oriented culture, in simple words the Cuban people separate the private and the working lives very clearly. The achievement vs. ascription dimension refers to the question of the status. In Cuban society, people belong to the ascription-oriented culture and the respect for a manager is based on hierarchy. Sequential vs. synchronic dimension defines two different ways of managing time, and the Cuban people belong to the synchronization-oriented dimension. In the end, the Cuban people fall more in the external control dimension. 4.3 Cuban culture under Ednlard T. Hall Cultural Dimensions Ednlard T. Hall is a famous researcher on cross cultural management. Hall’s cultural factors can be used to understand people from different cultural backgrounds, include high-context culture and low-context culture, monochromic action and polychromic action, high territoriality and low territoriality. First of all, Cuba belongs to a kind of high-context culture, similar with Trompenaars’ particularism. There are a lot of local unwritten rules of the culture, and much is taken for granted in the Cuban culture. Secondly, similar with Trompenaars’ time as sequence (monochromic) and time as synchronization (polychromic), most of the Cuban people can be polychromic-based action (Hall, 1966). In simple words, people often do many things at once and put relationship first, in addition to this, things are borrowed and shared often and easily. (Hall, 1983). Cuban people have high territoriality when working with the foreigners, which largely results from the political attitude of the communist society. 5 Impact of culture on leadership and organization behavior in Cuba With the development of the economic globalization, the importance of cross cultural management receives more attention. Culture can be defined as the characteristics of a particular group of people, including history, education, language, social, structure, religion, political, and economic. 5.1 Impact of culture on leadership in Cuba Leadership can be defined as a process of social influence in the accomplishment of a common task, and good leaders are not made born. As described above, cross cultural management models can be used to understand how to do the business in Cuba. Fig 2 Flag of Cuba 5.1.1 Impact of Cuban history on leadership The history of Cuba began with the arrival of Columbus in 1492, and in a long time it was controlled by the foreign countries, such as United States and Brazil. In the 20th century, Cuba made the alliance with the Soviets. Castro controlled Cuba for decades until the year 2006. In Cuba, the leaders have the concentrated power and members of an institution and organization accept the leadership very easily. Fig 3 Castro 5.1.2 Impact of Cuban education on leadership Speaking in essence, the Cuban education was strictly controlled by the government, and the school attendance is not very high. In addition to this, education has a strong political and ideological emphasis. In simple words, the Cuban education is not well-developed, and the leaders can easily influence the followers, also people get used to obey the instructions from the leaders. 5.1.3 Impact of Cuban language on leadership Spanish is the official language in Cuba, and most of the Cubans can speak it, because in a long time Cuba was controlled by Spain. In addition to this, Haitian Creole can be the second largest language. Language can play an important role in the leadership process, and it can be inferred that the leaders in Cuba are required to speak Spanish. 5.1.4 Impact of Cuban social structure on leadership Social structure can be identified as the relationship between entities or groups or as enduring and relatively stable patterns of relationship. The Cuban society believes that inequities are usual and a fact of the life. The equality can be accepted by all layers of the society, and the leaders of an organization can have a lot of power. Fig 4 Cathedral of Saint Christopher in Havana 5.1.5 Impact of Cuban religion on leadership Cuba has been a Communist country since 1959. Catholicism is much modified and influenced, and the most popular religion in Cuba is Santeria. The religion can maximize the cohesion between the members, and the leadership can take advantage of the religion, or else it will be the barriers. 5.1.6 Impact of Cuban politics on leadership Culture of a country can significantly influence the trade business, including the silk trade. People’s Republic of China has built a good relationship with Republic of Cuba for many years, which can be good for the silk trade in Cuba (Benjamin and Collins, 1985). To be more specific, the political attitude can be helpful in leadership. 5.1.7 Impact of Cuban economic on leadership Influenced by the political ideology, Cuba refused the free trade with the foreigners in the world market. Cuba carries out the planned economy for a long time and limits the private economy (Padilla and McElroy, 2007). The production are largely owned and operated by the government. Leaders from foreign countries may not easy in Cuba. 5.2 Impact of culture on organization behavior in Cuba Likewise, the impact of culture on the organization behavior must be also taken into account by the management. Organization behavior is a field of study that investigates the impact of individuals, groups and structures upon behavior within an organization. Organization behavior can be understood better, and the barriers can be eliminated. 5.2.1 Impact of Cuban history on organization behavior In a long history of the communist society, the Cubans get used to obey the rules from the leaders. In simple words, the individuals, groups and structures in Cuba share the same rules. In the process of cross cultural management, members of an institution or organization obey the group norms. 5.2.2 Impact of Cuban education on organization behavior Castro developed a fully state-operated education system, at the same time the private institutions are banned by the government. There is no advanced education system to build the organization behavior. In other words, the organization behavior of the local employees can be rebuilt in the process of cross cultural management. 5.2.3 Impact of Cuban language on organization behavior The official language in Cuba is Spanish, and the organization behaviors are based on the language. More importantly, language is the communication tool, and it can also decide the success of cross cultural management. Only on the basis of understanding the language, the organization behavior can be understood. 5.2.4 Impact of Cuban social structure on organization behavior Likewise, social structure decides many social systems, such as legal system, cultural system, economic system, and political system. Individuals and groups obey the social systems, and organization behavior can be influenced by the social systems. 5.2.5 Impact of Cuban religion on organization behavior To be more specific, the Santeria in Cuba developed from Catholicism by combining the religion of African slaves and some local Americans. Institutions or organizations from foreign countries can take advantage of the religion to bring people together. 5.2.6 Impact of Cuban politics on organization behavior The former leader Castro controlled everything for years and the Cuban people have been under control. Under such political environment, behaviors of individuals and groups are influenced by the external political factors. 5.2.7 Impact of Cuban economic on organization behavior Foreign leaders may find it difficult in leading the local Cuban employees, and some measures should be taken, for example hiring the local managers. The Cuban people have high territoriality when working with the foreigners, which largely results from the political attitude of the communist society in the world (SÃ ©ror and Arteaga, 2000). 6 Conclusion and Recommendations Due to the different political ideology, Cuba closed the door and operated differently. In conclusion, the characteristics of Cuban culture are different, and cross cultural management in Cuba needs to consider the characteristics. Recommendations will be made in the following to operate the silk trade in an effective and efficient way. 6.1 Leadership styles of cross cultural management in Cuba There are many kinds of leadership styles, which include authoritarian, paternalistic, democratic, laissez-faire, and transactional. Taking the Cuban cultural characteristics into account, the kind of paternalistic leadership style can be put into practices in the Cuban business world. The leaders encourage the employees to compete the tasks, at the same time they take care of the employees as a parent will do, because the local employees are influenced by the external political factor. In order to do the silk trade, the leaders have to deal with the potential barriers in Cuba. 6.2 Communication styles of cross cultural management in Cuba In Cuba, the official language is Spanish. As for the management, the communication styles can be assertive, aggressive, passive, and passive-aggressive. The best style for the management in Cuba can be the assertive communication. To be more specific, the leaders can communicate with the local employees in an assertive way. The language barrier can be solved by hiring the translators, and the institutions and organizations can hire the local employees as the middle management level, for they can carry out the business strategies better and communicate with the local employees easily. 6.3 Negotiation skills of cross cultural management in Cuba Under the different cultural background, some negotiation skills are necessary in the process of cross cultural management. By understanding the Cuban culture, leaders in Cuba can learn how to work with the Cubans and avoid the cultural barriers. It can be recommended that the first one negotiation skill is to learn to flinch. In order to make the silk trade with the Cubans, the businessmen need to respect the local rules and the employees, thus make them feel comfortable in the trade process. The second one is to recognize that customers often ask for more than they expect to get. In the process of silk trade, the Cubans are provided good products and services. After the customers recognize the products and services, the company can build better brand awareness to increase the sales and make profits in Cuba. 6.4 Management styles and requirements of cross cultural management in Cuba The management process is not easy, but it can significantly influence the silk trade in Cuba. During the process of cross cultural management, the management can consider the Cuban cultural factors, as explained in the above cultural dimensions. Especially, when making important decisions, the cultural factors need to be taken into account, as well as the problem-solving process and team management. 6.4.1 Decision-making of cross cultural management in Cuba The process of decision-making is not easy in a different cultural background. In the Cuban culture, the first one is to take the political factor into account. The government interface with free trade can be the biggest barrier in Cuba. The decision-makers need to understand the Cubans, for example, things can be borrowed and shared often and easily. Cuban people have high territoriality when working with the foreigners, so the institutions and organizations can cooperate with the local groups. In the end, results of the potential decisions need to be reasonably predicted under such circumstances. 6.4.2 Problem-solving of cross cultural management in Cuba When facing with the conflicts, the management needs to solve the problems. Unlike the conventional situation, the local cultural may be more complex, for the conflicts in Cuba may involve many parties. At this time, the foreigners need to understand how the local residents deal with the problem. For example, the members of this country believes that inequities are usual and accepted by all layers of the society, and the leaders of an organization can have a lot of power. In simple words, the foreigners can seek for the support of the leaders if they are encountering the barriers in Cuba. More importantly, people in Cuba belong to the category of high uncertainty avoidance, and money can be the effective and efficient to solve the current problems. 6.4.3 Team management of cross cultural management in Cuba As a communist society, the Cuban people are regarded as the group. It is known that Cuba is a collectivist culture. Under such political environment, people work together and share the property. They believe that all the Cubans are important and cooperation is important in the society. In the process of team management, the leaders can learn to motivate the employees and increase the cohesion power among the team members. In addition to this, the dominant values in the society are caring for others and quality of life, rather than the competition, achievement, and success. If team members share the same values, they can come together to complete the common goals. The last but not the least, the leaders have a lot of concentrated power. During the process of cross cultural management, leaders need to develop an understanding of the Cuban culture.

Allama Iqbal and the Concept of Muslim Nation

IQBAL' S CONTRIBUTION TO THE REAWAKENING OF THE MUSLIM WORLD Muhammad Aman Hob ohm Some time before his death the poet and philosopher Mohammad Iqbal, in whose memory this meeting is held, wrote the following quatrain: â€Å"When I depart from this world everyone will say: â€Å"He was known to me But in truth, none knows this traveller, Or what he said, and to whom nor whence he came. â€Å"I have neither the good fortune of knowing Iqbal personally nor am 11 an Iqbal scholar. When I was asked by the Honorary General Secretary, Pakistan Cultural Group, to participate in this meeting and to share with you some of my thoughts on the contribution made by Mohammad Iqbal to the renaissance of the Muslim World in general and to the re-awakening of Muslims of pre-partitioned India in particular, I accepted, mainly for the following two reasons:Firstly I feel that as a Muslim whose own understanding of Islam has been deeply influenced by Iqbal it was my duty to join you in paying homage to this great and noble soul repaying some of the debt of gratitude I owe him for enlightening me through his writings on so many aspects of Islamic teachings and for in-creasing my love and respect for the Messenger (peace be upon him) — and his message through Iqbal's inspired exposition of the religion of Islam, — the religion of my choice.Secondly acceptance of your kind invitation to address tonight lies in the fact that I hail from a country for which Iqbal has always had the highest esteem and what is more, a deep and abiding love and admiration i. e. Germany. Iqbal himself tells us in the preface to Payam-e-Mushriq the book in which his art has probably reached the height of power and perfection, that of the two great sages who have influenced him more than anyone else in his career as a thinker and poet, one was Maulana Jalal-ud-Din Roomi — who hailed from the East, the other was Goethe, who came from West.Iqbal went to Germany in 1906 when he studied p hilosophy at the Universities of Heidelberg and Munich. He presented his doctoral thesis entitled â€Å"The Development of Metaphysics in Persia† to the Munich University which, in November 1907, conferred on him the degree of Doctor of Philosophy. His thesis was an original contribution to the subject and it still retains its importance. During his stay in Heidelberg and Munich he developed deep admiration for Germany, German thought, and poetry.As every scholar of Iqbal knows there are innumerable instances in his writings, his letters and in recorded conversation with him which clearly indicate that the works of German philosopher and poets have been a source of great inspiration to him. I have in my possession a number of letters which Iqbal wrote to his German tutor in Heidelberg. These letters, some of them written in fluent German, express his love and admiration for Germany in a most touching and convincing way. â€Å"It is impossible for me†, writes Iqbal to h is tutor â€Å"to forget your beautiful country where I have learned so much†. My stay in Heidelberg is nothing now but a beautiful dream. How I'd wish I could repeat it†. â€Å"I am very fond of Germany. It has had great influence on my ideals, and I shall never forget my stay in that country†. Never shall I forget the days I spent at Heidelberg, where you taught me Goethe's Faust, those were very happy days, indeed†. — And a final quotation, â€Å"Germany was a kind of second home to my spirit. I learned much and I thought much in that country. The home of Goethe has found a permanent place in my soul†.Iqbal's stay in Europe from 1905 till 1908 has had, I think one can call it, â€Å"revolutionizing† effect on his attitude to life, and nowhere does this find a more forceful expression than in his poetry. Iqbal's career as a poet began during his school days. His earlier poems show him as a lover of nature and as a patriot to his count ry, undivided India. Iqbal was, indeed, an ardent Indian nationalist, until he went abroad. However, during his stay in Europe he had an opportunity of studying modern nationalism at close quarters in its arious manifestations, with the- result that he came to realize the fundamental, antithesis between the narrow creed of racial and geographical loyalty and the broad humanistic outlook of Islam. Now he was no longer the poet of a particular nations. Despite he became the poet of Islam, and as such I dare say the poet of humanity. Likewise, his penetrating study of Western philosophy and social thought at their source, so to say, his stay in Europe enabled him probably as the first Muslim in Modern lines, — to study Islam in the light of modern philosophical concepts.In this process and this is significant as it shows the mettle of which Iqbal was made, his faith in his religion — Islam and significance and lasting character of the fundamental values of Islam which far from weakening, gained so much in strength and conviction and assumed such dimensions that from now on he devoted himself wholly and solely to The Reconstruction of Religious Thought in Islam — to use the title, of his well known collection of lectures on the subject — he became the foremost Muslim thinker of our age.But we cannot say him the philosopher of Islam, for he was far more than a mere lover of wisdom. His feet were too firmly planted in the earth. The very essence of his teachings was movement, dynamism, creative activity and not passive contemplation. Art thou alive? Be enthusiastic, be a creator, Be a conqueror of the Universe like me Smash the World into pieces if it does not suit thee And bring forth another world from the depth of thy being It is irritating for a free man to live in a World made by othersHe who is devoid of creative power Is naught for me but an infidel and a heretic. This is the spirit which made him take upon himself the gigantic tas k of rousing millions of fellow countrymen, millions of human beings and making them cast off the moral inertia which had paralysed their mind and spirit in the course of centuries. And this is also the spirit which prompted him, perhaps even compelled him to associate himself actively with politics from the later 1920s till the day of his death. It is because the political ideas such as are taking shape in India today, may affect the structure of Islam†, Iqbal is reported to have said, â€Å"that I am interested in politics†. And he said elsewhere: â€Å"Politics has its roots in the spiritual life of man — Religion is a force of great importance in the life of the individual as well as of nations†. â€Å"And religion which in its highest manifestations is neither dogma nor priesthood nor mere ritual, can alone ethically pre-pare modern man for the burden of the great responsibility which the advancement of modern science necessarily involves†¦.It i s only by rising to a fresh vision of his origin and future, his whence and whither, that man will eventually triumph over a society motivated by an inhuman competition and a civilization which has lost its spiritual unity by its inner conflict of religious and political values†. So far Iqbal, the political thinker and visionary, who in this capacity too has found a place in history, through his famous presidential address at the Annual Session of the All India Muslim League at Allahabad in December 1930, in which he gave the world the concept of a consolidated, independent Muslim State in the Indo-Pakistan Sub-Continent.He thus became the founder, the originator of the Pakistan idea, though the word â€Å"Pakistan† was not coined by him. Iqbal's unique contribution to Muslim thought is his concept of the Ego and of the perfect man, as other speakers tonight are likely to dwell upon at length. This is a point, should like to make according to Iqbal –man can achie ve his highest possibilities only within and through society. This society must, however, fulfil certain conditions which Iqbal has formulated very clearly and which I may be permitted to enumerate, because of the importance which I personally attach to them.The ideal society must have a spiritual basis which is provided by the principle of Tawhid. â€Å"The state according to Islam, is only an effort to realize the spiritualism in a human organization†. â€Å"Islam, as a policy, is only a practical means of making this principle, the principle, of Tawhid, a living factor in the intellectual and traditional life of mankind. It demands loyally to God, and, this in my opinion is a pointed reference to British raj in lndia, not to thrones. And since God is the ultimate spiritual basis of all life, loyalty to God virtually amounts to man's loyally to his ideal nature. Iqbal further insists that it must centre around the Prophet (peace be upon him), that it must have a code †” the Holy Quran and a focus — Mecca, and it ought to apply itself to conquering the forces of nature. Iqbal was convinced that the decadence of the East as it obtained in his days and before, its economic and political disintegration were caused to a large ex-tent by its neglect of science. But let us not forget that he also demanded that his ideal society must maintain traditions, for traditions are a factor of stability. His ideal society is the Ummah as envisaged by Islam.His ideal man the Prophet (peace be upon him). At a time when the East was in an extremely distressing and difficult situation, defeated and humiliated by an adversity who seemed to be all powerful while the West stood at the apex of its glory, when no one would have given a frame for the Muslims and their future – he brought out in verse/and rhyme/and prose — thus laying the foundation for the resurgence of Islam of which we are witnesses — he brought out restated fundamentals, na y essentials of Islam in a clarity which cannot be surpassed.And by doing so he restored confidence in the hearts of millions of our brethren, fortified their belief and gave them new hope for the future. A future — and that was Iqbal's most cherished vision — in which alI Muslims would form an indivisible community, united in the belief that their religion, the religion of Islam — and here I may be permitted to quote Iqbal once again — that their religion, i. e. Islam is not a departmental affair. That is neither mere thought nor mere feeling, nor mere action; that it is the expression of the whole man. May God bless his soul.
