Work Based Learning in the Creative and Cultural Industries Assignment - 1
Work Based Learning in the Creative and Cultural Industries - Assignment Example When examining the swine flu and the responses that are a part of the work place and society, there is also a relation to the media and the way that information is portrayed to society. From one angle, the swine flu and the implications of this virus should be based on complete and truthful information. Having this would allow the public to respond in the correct way and would create a difference in how culture, businesses and different arenas of life looked at the flu. However, there are also other angles that the media adds into the swine flu and different pieces of news. Instead of basing this on complete fact and information, there is a change in the information that is presented. Often, this comes from limited knowledge on the swine flu. At other times, this is related to the cultural stigma that is surrounding what is happening. While writing this report, I found that it is important to recognize what the media is saying as well as how knowledgeable they are on a subject. It is important to look beyond cultural expectations, information that is presented at a surface level and the way that society responds as a whole as well as in places such as the work place. Looking at the way that media depicts certain ideas and being able to distinguish beyond this is essential to finding the real information and knowledge that is a part of different epidemics, such as the swine

Literacy Narrative Essay Example | Topics and Well Written Essays - 1250 words
Literacy Narrative - Essay Example As a result, I have not developed excellent English literacy and the confidence to use it. I realized that I can use my strengths of perseverance and good study habits to develop my English skills, but I continue to struggle because of my shyness and anxiety in speaking and writing in English. Nevertheless, I continue learning English through using personal, social, and academic resources, as well as imbibing positive psychology in learning a language that is so different in terms of values and structure to my native language, without weakening my cultural identity. My personal traits of shyness in using English resulted in anxiety that impeded my early progress in learning it. My school was a firm believer of immersion, where speaking in Chinese in the school is not allowed. Teachers easily embarrassed students who did not speak in English. My classmates and I preferred silence then, since we were not that good in English. This is what Kingston referred to as being tongue-tied in he r essay ââ¬Å"Tongue-Tied.â⬠Our tongues are tied due to not being able to speak a language that we have little knowledge of. One time, I forgot to speak in English in my class and my teacher berated me in front of so many people. I was so mortified, and since then I spoke very little. I did not want to make any mistake again. However, as I learned, bilingual education is also an effective means of teaching English to non-native speakers (Rhodes, Ochoa, and Ortiz 58). Bilingualism at the critical stage of my life would have helped my development of better English skills. The critical stage for me is during grade school (Gonzalez 3). Using Chinese to learn English would have helped me transition into English. By this time, however, I was not very confident in my English reading and writing skills. I became very conscious of my accent and choice of words because other students would laugh at me. I know they were just being children, but the impact on my self-esteem was devastati ng. The feeling of inferiority affected my motivation to learn English. I learned how to speak it in a form of conversation, but academic English is different. My shyness resulted in anxiety, which affected my confidence in learning English. To some extent, being a good student gave me high expectations of myself, which obstructed my language learning process. I am a good student and have strong studying skills. I have high grades in most of my subjects. English, however, is harder for me because I lack enough knowledge about it. It became my Achillesââ¬â¢ heel, and I felt disappointed with myself. This disappointment turned into a strong fear of failure. I did not want to fail as a language learner, and this hindered me from learning English. I also lacked practice in using English before, since we do not speak it at home. My parents wanted me to learn it fast, but they are not aware of how important the home environment is in learning new languages. In our neighborhood, we also did not use English. As with many non-native English learners, we lacked practice in everyday settings. Without practice, I did not feel confident in using English and I did not have anyone to test my skills on. That is also frustrating for students like me, who are used to attain their goals. When I came to America, I became more diffident as a language lea
Sexual Exploitation Essay Example | Topics and Well Written Essays - 1000 words
Sexual Exploitation - Essay Example Across the world, there are numerous women caught in the same trap as Meena. Women are the main victims of sexual exploitation since most societies disregard them. This is more so in countries like India where women are likely to be force into practices such as forced marriage. This paper focuses on the issue of sexual exploitation. The paper will involve an analysis of Kristof and WuDunn perspective on sexual exploitation as well as views by Meghan regarding women and girls as major victims of sexual exploitation. Chapter 1 of Half the Sky: Turning Oppression into Opportunity for Women Worldwide by Kristof and WuDunn tells the story of human trafficking for sexual exploitation purposes. The story of Meena, who was forced into commercial sex at a tender age, demonstrates the extreme exploitation of young girls in brothels. In Nepal, government agencies such as police seem adamant about the issue, which has led to increase in sexual exploitation. Moreover, some government employees such police officers act in support of the brothel owners since they are beneficiaries of the sexual services offered in the brothels. Globalization has had great effects on sexual exploitation. With improved transport system, human trafficking is more rampant. Sexual exploitation is an offence against human dignity. The malpractice if often associated with forced prostitution and human trafficking (WuDunn and Kristof 3-6). As opposed to the belief that most people engage in prostitution willingly or for economic purposes, a considerable number of people are forced into prostitution. Globalization has resulted in an alarming increase in human trafficking. ââ¬Å"While there has been progress in addressing many humanitarian issues in the last few decades, sex slavery has actually worsenedâ⬠(Kristof and WuDunn 11). The increased in sex slavery is attributable to increased human trafficking. Human trafficking is mainly related to globalization. With improved

Spreading Inovation Article Example | Topics and Well Written Essays - 500 words
Spreading Inovation - Article Example The program trains professionals who serve low-income children, mostly in health centers. In the program, health providers are taught how to integrate oral health risk assessment and fluoride varnish applications into services that are usually offered to young children (DHHS, 2012). There are particular main problems that affect the oral health of children. These problems include tooth decay, sucking of the thumb, tongue thrusting, and lip sucking. Although baby teeth will later be replaced with permanent teeth, keeping the teeth of children healthy is critical to their health and well-being (Kramer et al., 2013). The mouth has many bacteria, although most of them are harmless. Good oral health care can help to keep the bacteria at bay. Nonetheless, without appropriate oral hygiene, these bacteria can cause oral infections such as gum disease and tooth decay. Many children, especially in low-income families face the problem of tooth decay, and it is important that they get help in order to overcome these issues (Salem et al., 2012). The Colorado community-based health program is aimed at ensuring that the health care professionals are well-equipped to ensure that childrenââ¬â¢s oral health is maintained. As the manager of Colorado Health Center, I find ââ¬Å"Cavity Free at Three" program to be a very noble idea. The first step in the introduction of the program to the organization is to offer training for all health professionals that work in the organization. Proper training will ensure that every employee understands the idea behind the innovation in order to implement it. The training will involve explaining to the staff the importance of the program and what the organization aims to achieve. The organization will collaborate with the community and other health organizations in its implementation. In order to maintain the program for a long time, the organization will ensure that it sets aside enough funds to be
Potential Short-Run Economic Impacts of the Recent Japanese Disaster Essay
Potential Short-Run Economic Impacts of the Recent Japanese Disaster on the Australian Economy - Essay Example According to the research findings, it can, therefore, be said that specifically, the study of microeconomics allow us to have better understanding about the movements of money from the local firms to household which often times is dictated by the movements of a curve in demand and supply of goods and services in domestic and global markets. Furthermore, the study of microeconomics allows us to reflect on interrelated between salary and wages, employment and unemployment rate, its potential effects on business performances, and the economy as a whole. Based on the Keynesian model, economic recession and contractions are usually caused by the presence of inadequate demand for Australian goods and services. In fact, the post-Keynesian economics proposed the theory of aggregate employment such that the distribution of income, economic growth and developments in trading practices are dictated by the demand-side curve, Although the post-Keynesian economic theory suggests that the market o f a competitive economy is dictated by the demand-side curve and will never attain or satisfy the idea of full employment, economists generally believe the presence of inadequate demand for goods and services can cause a serious market failure and economic problems. With this in mind, the presence of inadequate demand can result in the presence of high unemployment rate. The recent tsunami in Japan has to lead to a significant decrease in the demand for Australian coal and iron ore. The problem with a sudden decrease in demand for goods and services is that the business owners of local firms in Australia may simply lay-off some of its current employees.

Stem Barks of Bauhinia Acuminata | Analysis
Stem Barks of Bauhinia Acuminata | Analysis Materials and Methods Plant collection The stem barks of Bauhinia acuminata L. were collected from Rajshahi university campus, Bangladesh, in the month of September, 2013. The plant was authenticated by a taxonomist of Department of Botany, University of Rajshahi. A voucher specimen (Voucher No. MN-13) was deposited to the herbarium in the Department of Botany, University of Rajshahi. The stem barks were then washed separately with fresh water to remove dirty materials and were shade dried for several days with occasional sun drying. The dried barks were then ground into coarse powder by grinding machine and the materials were stored in dark at room temperature for future use. Extract preparation The extraction was performed according to method described by Alam el al. (Alam et al., 2002). About 400 gm of dried powdered stem bark were taken in an amber colored reagent bottle (2.5-liter capacity) and the materials were soaked in 2.0 liter of 100% methanol. The bottle with its contents were sealed and kept for a period of about 7 days with occasional shaking and stirring. The whole mixture was then filtered through cotton and then through Whatman No.1 filters paper and were concentrated with a rotary evaporator (Bibby Sterlin Ltd, UK) under reduced pressure at 45Ãâà °C temperature to afford crude extract of the bark. The crude extract was mixed with 90% methanol in water to obtain a slurry of satisfactory volume of 100ml. The slurry was taken in a separating funnel and added equal amount of different partitioning solvent sequentially as like n-hexane, chloroform, ethyl acetate and finally water. The funnel was shaken vigorously and allowed to stand for a few minutes for sep aration of the compounds according to their partition co-efficient and thus extracts were prepared for the experiment purpose. The process was repeated three times. At last, the different fractionated parts were evaporated using rotary evaporator at 400C to obtain n-hexane fraction (NHF, 1.12 gm), chloroform fraction (CHF, 1.33 gm), ethyl acetate fraction (EAF, 2.27 gm) and aqueous fraction (AQF, 8.86 gm) respectively. Chemicals 1,1-diphenyl-2-picrylhydrazyl (DPPH), potassium ferricyanide, catechin (CA), ferrous ammonium sulphate, butylated hydroxytoluene (BHT), gallic acid (GA), ascorbic acid (AA), AlCl3, trichloro acetic acid (TCA), sodium phosphate, sodium nitrate, ammonium molybdate, 2-deoxy ribose, sodium hydroxide, EDTA and FeCl3 were purchased from Sigma Chemical Co. (St. Louis, MO, USA); potassium acetate, phosphate buffer, thiobarbituric acid(TBA),Ãâà HCl, H2SO4, H2O2were purchased from Sigma-Aldrich, vinblastine sulphate (VBS) from Cipla India, folin-ciocalteuss phenol reagent and sodium carbonate were obtained from Merck (Dam-stadt, Germany). Determination of total phenolics Total phenolic contents in the extracts were determined by the Folin-Ciocalteu method described by Singleton et al. (Slinkard Singleton, 1977). 40 Ãâà µl of the extract/fractions (250Ãâà µg/ml) were taken in test tubes and to each 3.16 ml of water was added to make up the volume 3.2ml. 200 Ãâà µl of folin-Ciocalteu (Undiluted) reagent solution was added into the test tubes and kept for 5-8min. 600 Ãâà µl of sodium carbonate (20%) solution was added into the test tubes and shake to mix. The test tubes were incubated for 2 hours at 20Ãâ¹Ã
¡C to complete the reaction. Then the absorbance of the solution was measured at 765 nm using a spectrophotometer (Shimadzu, USA) against blank solution. A typical blank solution contains all reagents except plant extract or standard solution. Standard Gallic acid solutions (50-250ÃŽà ¼g /ml) concentrations were also treated as above. The total content of phenolic compounds in plant methanol extract and in different fractions wa s expressed as Gallic acid equivalent (GAE)/gm of dry extract in respect to standard gallic acid curve equation (y = 0.0008x 0.005, RÃâà ² = 0.975). Determination of total flavonoids Total flavonoids were estimated using aluminum chloride colorimetric assay described by Zhishen et al. (Zhishen, Mengcheng, Jianming, 1999). To 0.5 ml of samples/standard, 150 Ãâà µl of 5% sodium nitrate and 2.5 ml of distilled water were added. After 5 min, 0.3 ml of 10% AlCl3 was added. At 6 min, 1 ml of 0.001M NaOH and 0.55 ml distilled water was added to the mixture and left at RT for 15 min.Ãâà Absorbance of the mixtures was measured at 510 nm. Total flavonoid contents were expressed in terms of catechin equivalent, CAE /gm of dry extract in respect to standard curve equation (y = 0.0178x+0.0524, RÃâà ² = 0.9862). Determination of free radical scavenging activity DPPH radical scavenging activity Free radical scavenging ability of the extracts was tested by DPPH radical scavenging assay (DRSA) as described by Braca et al. (Braca et al., 2001). Aliquots of 2.5mL of methanolic solution containing sample at different concentration was mixed with 2.5 ml of 0.008% DPPH solution in methanol. The reaction mixture was vortexed thoroughly and left in the dark at room temperature for 30 minutes. The absorbance of the mixture was measured spectrophotometrically at 517 nm. Ascorbic acid was used as reference. Percentage DPPH radical scavenging activity (% DRSA) was calculated by the following equation, % DRSA = (A0-A1/A0) x 100 Where, A0 = Absorbance of control and A1 = Absorbance of sample. IC50 values denote the concentration of sample required to scavenge 50% DPPH free radicals. Hydrogen peroxide scavenging activity Hydrogen peroxide scavenging activity of extract was assessed by the method described by Zhang et al. (Zhang He). Aliquot of 1.0 ml of 0.1mmol/L H2O2 and 1.0 ml of various concentrations of extracts were mixed. Followed by 2 drops of 3% ammonium molybdate, 10 ml of 2M H2SO4 and 7.0 ml of 1.8 mol/L KI. The mixed solution was titrated with 5.09mmol/L Na2S2O3 until yellow color disappeared. The extent of scavenging of hydrogen peroxide was calculated as: % scavenging of hydrogen peroxide = [(V0-V1) / V0] ÃÆ'- 100 Where, V0 = Volume of Na2S2O3 solution used to titrate the control sample in the presence of hydrogen peroxide (without sample), V1 = Volume of Na2S2O3 solution used in the presence of samples. Hydroxyl radical scavenging activity Hydroxyl radical scavenging activity (HRSA) of the extracts was determined by the method of Halliwell et al. (Halliwell, Gutteridge, Aruoma, 1987) with a slight modification. 100 Ãâà µl of various concentrations of extracts were mixed with 100 Ãâà µl of hydrogen peroxide (10mmol/L). To this 200 Ãâà µl premixed FeCl3 (100mmol/L) and EDTA (100mmol/L) solution (1:1;v/v) was added. Followed by addition of 500 Ãâà µl of 2.8mmol/L 2-deoxyribose in phosphate buffer (PH7.4) and finally the reaction was triggered by adding 100 Ãâà µl ascorbate (300mmol/L).Ãâà Then the reaction mixture was incubated at 37.5Ãâ¹Ã
¡C for 1 hour. To the above reaction mixture 2 ml of TCA (2.8% w/v aqueous solution) and 2 ml of TBA (1% w/v aqueous solution) was added. The final reaction mixture was heated for 15min in boiling water bath, cooled and absorbance was taken at 532nm using a spectrophotometer. The hydroxyl radical scavenging capacity was evaluated with the inhibition percentage of 2-deoxyribose oxidation on hydroxyl radicals. The percentage of hydroxyl radical scavenging (%HRSA) activity was calculated according to the following formula: % HRSA = [A0 (A1-A2] ÃÆ'-100/A0 where A0 is the absorbance of the control without a sample. A1 is the absorbance after adding the sample and 2-deoxyribose. A2 is the absorbance of the sample without 2-deoxyribose. REFERENCES Alam, A., Rahman, M., Baki, M., Rashid, M., Bhuyan, M., Sadik, G.
