Antibiotic use, environment and antibiotic resistance : A qualitative study among human and veterinary health care professionals in Orissa, India.

Sahoo, Krushna Chandra January 2008 (has links)
<p>Objective: To explore views of medical doctors, veterinarians and drug sellers on use of antibiotics on humans and nonhumans and on factors that influences the development of resistance to antibacterial agents. Further, to look at the bi-directional relationship between antibiotic use and environment. </p><p>Methods: The study was a qualitative explorative interview study, analysed using conventional content analysis. It was conducted in Orissa, India. Data were collected by face to face semi structured interview. The interviews were tape recorded and transcribed into Oriya, then translated in to English. Each paragraph or sentence was coded. Similar codes were clustered together and collapsed into sub categories and categories. The main themes were allowed to emerge, based on the relationship between categories.</p><p>Findings: The main finding of the study was mishandling and abuse of antibiotics in patients as well as at professional level due to weak implementation of legislation, which appears to be the major cause of antibacterial agent resistance. Incomplete course or dose due to poverty in rural area and self medication in urban area are more common. The study also showed that climatic factors, pollution and population density are the major ecological factors which influence antibiotic prescriptions. Another major finding of this study was that, due to improper disposal system of pharmaceuticals; antibiotics are contaminating air, water and terrains which can cause major risk to aquatic and grazing animals. </p><p>Conclusion: This study emphasises the need for comprehensive actions including information, training, legislation and education at all levels of drug delivery system to rationalize antibiotic use by improving prescribing pattern and creating awareness among consumers. Proper disposal of pharmaceutical wastes is required to prevent the contamination of environment from pharmaceutical pollutants. Further study is essential concerning environmental impact of antibiotics.</p><p>Key words: Antibiotic use; antibiotic resistance; environment; qualitative; conventional; content analysis; veterinarians; medical doctors; drug sellers; Orissa; India.</p>

Social Media Marketing vs. Prevalent Marketing Practices Master Thesis : A Study of Marketing Approaches for Micro firms in Sweden

Tariq, Muhammad, ghaffar, Abdul January 2010 (has links)
Background In Sweden almost 90% of businesses are micro in nature which plays a pivotal role in the economy by generating employment opportunities as well as serving a source of instilling entrepreneurial spirit and innovation. Due to their invaluable contributions to the economy, their survival through revenue generating marketing practices has become an area of much more interest than ever realized before. A common misconception prevalent is that marketing in micro businesses is just a miniature of larger enterprises. This is why earlier researchers have paid scarce treatment to marketing practices in micro businesses as evident from the scant published material on the topic, making it an intriguing area to study. Currently much hype has been created about social media applications like Facebook, Twitter, LinkedIn etc and their marketing value for small businesses. It is therefore, in this thesis we study social media and prevalent marketing practices in the context of micro business. Purpose Micro firms are often cash-strapped which limits their revenue generating ability through prevalent marketing practices which are resource intensive. In the back drop of all the hype about social media as a marketing tool we got the clue to find the right marketing approaches for these businesses regarding the choice of prevalent practices and social media as a new marketing tool. To achieve this purpose, we have formulated the following research questions.RQ1.Which of the two types of marketing is more effective in terms of targeted segment coverage and expenditures? RQ2.Which marketing approach enables micro firms to maintain better relationships with customers? RQ3.Whether or not it is the right time for micro firms in Sweden to adopt social media marketing practices? Method A qualitative approach has been used to achieve the exploratory purpose of the thesis. Overall; eight micro firms were chosen from a convenience sample, representing different regions and industries of Sweden. In the first phase, two pilot semi-structured interviews were conducted to attain a better understanding of the phenomenon under study. Later, six more semi-structured interviews were carried out from micro businesses representing different sectors in Skövde, Mariestad and Jönköping Counties. Conclusion This thesis suggests that micro businesses are mostly marketing weak organizations (MWO) as they are sales oriented and see marketing as more of a luxury. Micro businesses in the sample reveal a tendency to carry out marketing activities in a haphazard manner which limits their likelihood of achieving their targets. It has also been indicated that conventional approach to reach target segments, still has a strong effect on micro firms in Sweden and is therefore more appropriate for them as majority of their customers are geographically concentrated as well as a major strata of these are yet to start active participation on the social media landscape. In terms of costs social media Given, the small population of Sweden, it has also been showed that micro businesses are keeping good customer relationship with customers via word-of-mouth marketing which is considered as instrumental for success of majority of micro business. At the same time, this finding does not indicate any clear picture as to which form of marketing is doing better for these businesses. In terms of social media adoption the findings indicate that micro businesses see social media as a great marketing opportunity in which micro businesses can compete on a level playing field with their larger counterparts. This study also concludes that social media is in infancy stages of its development in Sweden as people though they are present on the social media landscape, but have not yet, thought of it as a mainstream marketing channel. Therefore, it is suggested that micro firms in Sweden need to adpot a (high volume, low expense) is more effective only when used in tandem with conventional marketing (low volume, high expense) approaches. It is therefore suggested that micro businesses can use a blend of social and conventional marketing practices till the time that the social media network externalizes to a greater extent. wait and see approach for the time being and start preparing to capitalize on social media soon when it becomes ripe and ready for marketing.

Performance of Islamic Banking and Conventional banking in Pakistan : a Comparative Study

Moin, Muhammad Shehzad January 2008 (has links)
Islamic banking and finance in Pakistan started in 1977-78 with the elimination of interest in compliance with the Principles of Islamic Shari’ah in Islamic banking practices. Since then, amendments in financial system to allow the issuance of new interest-free instrument of corporate financing, promulgation of ordinance to permit the establishment of Mudaraba companies and floatation of Mudaraba Certificates, constitution of Commission for Transformation of Financial System (CTFS), and the establishments of Islamic Banking Department by the State Bank of Pakistan are some of the key steps taken place by the governments.   The aim of this study is to examine and to evaluate the performance of the first Islamic bank in Pakistan, i.e. Meezan Bank Limited (MBL) in comparison with that of a group of 5 Pakistani conventional banks. The study evaluates performance of the Islamic bank (MBL) in profitability, liquidity, risk, and efficiency for the period of 2003-2007. Financial ratios (12 in total) such as Return on Asset (ROA), Return on Equity (ROE), Loan to Deposit ratio (LDR), Loan to Assets ratio (LAR), Debt to Equity ratio (DER), Asset Utilization (AU), and Income to Expense ratio (IER) are used to assess banking performances. T-test and F-test are used in determining the significance of the differential performance of the two groups of banks. The study found that MBL is less profitable, more solvent (less risky), and also less efficient comparing to the average of the 5 conventional banks. However, there was no significant difference in liquidity between the two sets of banks. The reasons are due to the facts that conventional banks in Pakistan have longer history and experience in doing banking business and hold dominating position in the financial sector with its large share in the overall financial assets of Pakistan, as compared to Islamic banks, which in true sense, started only a few years back with all letter and spirit.     Albeit, the study found that MBL is less profitable, more solvent (less risky), and less efficient during 2003-2007, however, it is improving considerably over time indicating convergence with the performance of the conventional banks.

Examining ethics from a moral point of view framework: a longitudinal analysis

Walker, Kent R. 27 July 2007 (has links)
By use of interview data, this thesis investigates how two moral points of view, the Conventional and Radical, held by study participants relate to: 1) factors that influence ethics; 2) role models of a self-defined well-lived life; 3) factors that help and hinder participants from living their well-lived life; and, 4) experience of pressures to compromise and freedom to live out their ideals within organizations. A longitudinal analysis is applied comparing participant moral point of view as students, to participant perceptions since entering the workforce as university graduates. The results show differences and similarities within the four areas of interest based on moral point of view. The implications of finding differences in participant perceptions based on moral point of view are discussed, and areas for future research are offered. / October 2006

Production and behaviour of four strains of laying hens kept in conventional cages and a free run system

Singh, Renu 05 1900 (has links)
Production, egg quality, behaviour, and physical condition were compared from Wk 20 to Wk 50 among three beak- trimmed commercial laying strains, Lohmann White (LW), H & N White (HN), Lohmann Brown (LB), and a non-commercial Cross between Rhode Island Red (male) and Barred Plymouth Rock (female) in conventional cages and in floor pens. All chicks were reared in their respective environments, and 450 and 432 pullets were housed at 18 and 7 weeks of age in cages and floor pens respectively. Hens in cages were provided with 688 cm2/bird and those in pens with over 6,000 cm2/bird, both of which are more than provided by commercial standards. Body weights and eggshell weights were higher for birds in floor pens than those in cages, and although they increased with age, body weight of hens in cages decreased at Wk 50. White-egg layers (LW, HN) used perches and nest boxes more than Brown-egg layers (LB, Cross). During the laying period, mortality was higher for all strains in cages and during the rearing period mortality was higher in floor pens for LB hens but not other strains. No aggressive behaviours were found, but the frequency of gentle feather pecking and pecking at the enclosure was higher in cages than in floor pens. Feather condition deteriorated over time in cages mainly because of contact with the cage wires whereas in floor pens, feather condition of birds at Wk 20 was not different from that at Wk 50. The frequency of keel bone deformities was higher for White-egg layers than for Brown-egg layers in cages and was higher for Cross hens than other strains in floor pens. Claws were longer in cages than in the floor pens. Foot condition was worse in floor pens than in cages. The welfare indicators used in this study showed that cages restricted the hens' behaviour compared to floor pens and resulted in higher laying period mortality, reduced body weight and deteriorated feather condition than floor pens. Both systems had advantages and disadvantages in regard to the hens’ health and welfare. The use of environmental complexities was strain specific in floor pens. The environment by genotype interactions suggests that the strain should be considered when considering alternative housing systems.

Water quality from advanced and conventional treatment process of raw water relating to quality and quantity

Lin, Jen-Yao 29 June 2011 (has links)
The purpose of this study is to study the effect of water quality and quantity of raw water on advanced and conventional treatment processes. We are using data of water quality and quantity to investigate difference of quality of treated water in water treatment plant. Finally we compared items of ware quality ( turbidity, free residual chlorine, total hardness, conductivity, pH, NH3-N) whether passed the Taiwan¡¦s national standard of drinking water or not. We are hoping the treated drinking water will all fit the goal of high quality. Results show that high variation of turbidity was found from May to October in every year. The high turbidity was frequently occurred from 9.9% (2008) to 39.5% (2010). It indicated the worsen trend of water quality of raw water is increased yearly. In all monitoring items of water quality, turbidity, conductivity, NH3-N was greatly influenced in seasons from June to September. The rest items had no significant affect by season¡¦s variation. The removal efficiency in items of water quality of advanced and conventional WTP we found there were high value at hardness and TDS with 49.3% and 43.3% respectively. These items, water quality of treated water (such as turbidity, free residual chlorine, total hardness, conductivity, pH, NH3-N), were all pass the current drinking standard in Taiwan ( i.e., turbidity¡Õ2NTU¡BTDS¡Õ500mg/L¡B6.0¡ÕpH¡Õ8.5¡B0.2mg/L¡Õfree residual chlorine¡Õ1.0mg/L¡BNH3-N¡Õ0.1mg/L ).

A Study of Businesses Acquiring Government R&D Subsidies: A Case Study of Conventional Industry Technology Development (CITD)

Huang, Ya-ling 01 September 2011 (has links)
To improve Taiwan's competitiveness, Taiwan's government actively encourages businesses to commit to innovative R&D activities by implementing R&D subsidies and incentives. They hope to accumulate intellectual capitals and nurture enough technical professionals to promote industrial upgrades and stimulate economic development. When applying for R&D subsidy, the application must go through the proper approval process. Approved applications will be awarded with substantial financial assistance to fuel further innovations such that R&D subsidy has become critical to many companies. This study used the "Conventional Industry Technology Development"(CITD) as an example and classifies the R&D subsidy applications for analysis based on the 5 variables: company's basic information, program type, commitment to R&D, past experience in applying for R&D subsidy, and strategic alliance with other institutions. Logistic regression is expected to sum up factors that are significant in obtaining R&D subsidies and formulate a predictive model. This enables the government to re-examine its policies and understand the conventional manufacturers' commitment to R&D. Furthermore, the study may assist the companies to assess their chances in obtaining R&D subsidies and serve as a reference for future endeavors. The study suggests that the factors most critical for companies to obtain R&D subsidies are the number of employees, capital size, number of government subsidies already obtained, number of companies non-R&D outsourced to, whether R&D intensity has increased for the past 2 years, and whether R&D funding has increased for the past 2 years. Although plan's duration and non-R&D outsourced dollar amount may have some influence, their impact was not obvious in the model.

A Genetic Algorithm For Tsp With Backhauls Based On Conventional Heuristics

Onder, Ilter 01 September 2007 (has links) (PDF)
A genetic algorithm using conventional heuristics as operators is considered in this study for the traveling salesman problem with backhauls (TSPB). Properties of a crossover operator (Nearest Neighbor Crossover, NNX) based on the nearest neighbor heuristic and the idea of using more than two parents are investigated in a series of experiments. Different parent selection and replacement strategies and generation of multiple children are tried as well. Conventional improvement heuristics are also used as mutation operators. It has been observed that 2-edge exchange and node insertion heuristics work well with NNX using only two parents. The best settings among different alternatives experimented are applied on traveling salesman problem with backhauls (TSPB). TSPB is a problem in which there are two groups of customers. The aim is to minimize the distance traveled visiting all the cities, where the second group can be visited only after all cities in the first group are already visited. The approach we propose shows very good performance on randomly generated TSPB instances.
