Risk Factors in the progression from tuberculosis infection to disease

Ward, Heather A 07 January 2005
Tuberculosis (TB) is a two-stage disease, acquisition of infection and progression to disease. A complex interaction exists between the individual and their environment that determines who acquires infection and who progresses to disease. According to TB literature, 10% of individuals with infection will develop TB disease (1;2). Tuberculosis has been described a disease of poverty, but other factors may be important. The contribution of both individual measures, such as ethnic origin, gender and age and area-level measures, or socio-economic factors, to this two-stage process is not well understood. Understanding tuberculosis epidemiology and identifying those at risk for developing TB is important for effectively controlling the disease. The objective of this study was to determine the individual (age, gender, ethnic origin, geographic location) and area-level measures (income, home ownership, housing density, education, and employment) that contribute to the progression from tuberculosis infection to disease. Data from all Canadian-born Caucasians, Status Indians, and non-Status Indians and Metis, with an initial positive tuberculin skin test (TST) documented in the Saskatchewan TB Control database from January 1, 1986 to January 31, 2002 was analyzed. Exclusion criteria included any previous BCG vaccination, treatment for latent TB infection, or missing data. Individual data was obtained from the TB Control database. Area-level measures were obtained by matching individual postal codes with Canada census data to obtain information from enumeration areas. Outcome was time to TB disease at > 1 month following a documented positive tuberculin skin test. Analysis was completed using Cox regression proportional hazards model. 7588 individuals with a positive tuberculin skin test were included in the study and of these 338 (4.5%) developed TB disease. Thirty-four out of 4140 (0.8%) of Caucasians, 183 out of 2649 (6.9%) of Status Indians and 121 out of 799 (15.1%) non-Status Indians and Metis developed TB. The rate of progression to TB was 5.6/1000 person years for the entire study population. The incidence for Caucasians was 0.9/1000 person years, 7.7/1000 person years for Status Indians and 16.0/1000 person years for non-Status Indians and Metis. In the Cox regression model, including individual and area-level measures, the risk factors association with the progression to TB was age and ethnic origin (< 19 years of age HR 3.7, 95% CI 2.8 - 4.8 compared to > 19 years and ethnic origin HR 5.1, 95% CI 3.0 - 8.6 for Status Indians and HR 7.4, 95% CI 4.1-13.3 for non-Status Indians and Metis both compared to Caucasians). No socio-economic factor was consistently associated with progression to disease. We have found that age and ethnic origin are associated with an increased risk of TB infection progressing to disease. The differences in TB rates between Saskatchewan Caucasians and Status Indians, non-Status Indians and Metis can be explained by Grigg's natural history curve of TB epidemiology within a population (3). The Aboriginal population of Saskatchewan is much earlier in its epidemic resulting in higher disease rates compared to the Caucasian population. Identifying those at risk of developing TB and understanding the determinants of TB epidemiology are important for establishing successful TB control programs.

Can't Be Tamed: A Feminist Analysis of Apocrypha and Other Scripture

Ballard, Catherine Alison 20 April 2012 (has links)
This paper is my own unique feminist analysis of certain apocryphal texts. Though the texts I use have common themes, they are divided into what I consider the three most societally important aspects of an ancient woman’s identity: virgin, mother, and whore. The Acts of Thecla and The Acts of Xanthippe and Polyxena deal with virginity. II Maccabees, The Martyrdom of Perpetua and Felicitas, and select chapters of Augustine’s Confessions represent motherhood. Finally, the hagiographies Life of Pelagia and Life of Mary navigate through the mire of sexualities that deviate from norms.

The origin of naked barley (Hordeum vulgare L. ssp. vulgare) studied bythe nud gene

Gustafsson, Dan January 2013 (has links)
The exact origin of the peculiar naked barley is somewhat illusive. There   is a debate whether it has a single, monophyletic origin or a multiple, paraphyletic origin. It is from previous Asian studies on naked   barley known that a mutation   or a deletion of the nud gene expresses the   naked seed phenotype. Not much   investigation has been done outside of   Asia, least of all in the Nordic countries, on what gives naked   barley its character. Therefore this   study was set up to examine if   the Nordic variant of naked barley shares   the same nud allele as the Asian   and thus has a   close connection with it, or   if they have independent mutations. I   could confirm that the known alleles of the nud gene do determine the seed character of barley. Most of the   results of the PCR genotyping confirmed the phenotype of the tested   accessions, both naked and hulled barleys. However, one visually phenotyped naked   barley cultivar (NGB4580) still amplified with the known primers that would   match the Asian hulled allele, meaning that the Nordic accession NGB4580 of   naked barley did not carry the known nud   deletion. This suggests that naked barley has arisen independently in Asia   and in the Nordic countries.

An Assessment of Consumers’ Willingness to Pay for Attributes of Milk and Dairy Products with the 100% Canadian Milk Symbo

2013 July 1900 (has links)
Consumers are becoming increasingly concerned about their foods and more particularly, the origin of their foods and the ingredients they contain. In light of the demand for additional origin information, the 100% Canadian milk branding initiative was launched in 2009 as a means of informing consumers about the origin of milk in their dairy products. The information is indicated by the presence of the 100% Canadian milk symbol on dairy products and can be characterized a form of co-branding. The literature on co-branding stipulates that co-branding can result in changed product perceptions either negatively or positively. In addition, the willingness to pay (WTP) literature stipulates that WTP is determined by product attributes and individuals’ characteristics. This thesis therefore seeks to ascertain the factors affecting consumers’ preferences and WTP for products with the 100% Canadian milk symbol. Specifically, the effects of individual characteristics such as health consciousness, patriotic values and risk perceptions on preferences for dairy products with the symbol are evaluated. Concurrently, the study explores the relationship between respondents’ knowledge of the Canadian dairy industry and WTP for the symbol. Data were gathered from a total of 1012 milk and ice cream consumers using two nationwide internet surveys. Estimations are carried out using the Multinomial Logit (MNL) and the Random Parameter Logit models (RPL). The results suggest that consumers in general have positive perceptions of milk and ice cream with the 100% Canadian milk symbol but negatively perceive store brand and organic labels. However, in some cases, combining a store brand label or organic label with the 100% Canadian milk symbol, are shown to alter consumers’ perceptions of the product. Some socio-demographic variables and individual characteristics were also found to be influential in intended purchase behaviours and WTP for milk and ice cream. The findings from this study provide information on consumers’ perceptions and attribute preferences and are expected therefore to contribute to the marketing strategies of the Canadian dairy industry as a whole.

Marketing Opportunities for Companies Back-shoring to France

COGNE, Edouard, GUYARD, Arnaud January 2012 (has links)
Purpose of this paper: This paper aims at studying which marketing opportunities companies back-shoring to France can leverage through Mass Media communication. Design/methodology/approach: 2 analyses are performed: a Media analysis studies the message that is sent to consumers. A survey is then carried out to discover how consumers perceive what is broadcast. Hypotheses are designed based on the former, and guide the design of the survey. The discussion and analyses are made under a marketing approach. Findings: The phenomenon is globally understood, but Media are not always necessarily the most appropriate tool for back-shoring companies to communicate about the three marketing dimensions identified during Media analysis: Made-in-France, Social issues related to Sustainable Development and the Impact of Political Messages. Research limitations/implications: The analyses are restricted to a study of French Mass Media, and of French consumers. Therefore, this study cannot be generalized to other countries. What is original/value of paper: This paper helps complete the limited literature on back-shoring, especially in the area of Marketing. This study intends to benefit back-shoring companies willing to develop their marketing strategy.

Nyheternas födelse : En kvantitativ undersökning av källor till lokala nyheter i lokaltidningar

Ohlsson, Matilda, Spogardh, Johanna January 2008 (has links)
The purpose of this thesis was to study the origin of the local news in local newspapers. Do the news originate mostly from the police, the municipality, from press releases or from the reporters own ideas? We also wanted to find out what kind of content predominated in texts with its origin in press releases respectively the reporters own ideas. Of course we also wanted to find out if there were any similarities or differences between the two studied newspapers. We used a type of constructed week, but with non random selection instead of random. We chose one of each weekday the newspapers were published and studied the news covered in the papers that specific day. We talked over the phone with the news editors and the reporters and simply asked them about the origin of each news text separately. The results showed that every fourth text originates from the police, and that police news often ends up as news items rather than articles. We also came to the conclusion that local newspapers use fewer press releases than earlier research has shown. Only one sixth of the news studied originates from press releases, which is less than we thought it would be. News with its origin in advertisements was less often found. News with its origin in the reporters own ideas deal with various subjects. A text that is written on the basis of a press release on the other hand is often about some kind of event and has almost always a very positive tone. We could not notice any remarkable difference between the two studied newspapers.

Challenges in International Joint Venture of Clothing Retail Industry : Marks & Spencer in Taiwan

Santosa, Budianto 19 June 2010 (has links)
When deciding to internationalize, companies face the need to develop a foreign market strategy and a foreign market expansion strategy especially when the foreign country has very different culture from home country. Most research of company process of internationalization nevertheless is based on entry mode and mostly successful businesses. Here, the failure of joint venture between Marks and Spencer (M&S), one of the biggest of British Retail Company and Uni-President Corporation, the biggest food and drink enterprise in Taiwan is examined. Its recent large-scale withdrawal from such activity is also measured to some extend of theories about internationalization and marketing failure. The qualitative method and a case study were carried out. In addition, in-depth interviews with Uni-President representative, M&S Visual Display Manager and two groups of M&S customers and non M&S customers are the primary resources of data. The research suggested the joint venture between the two companies created many problems due to two extremely different cultures and lack of understanding of the local market. M&S marketing strategy did not draw Taiwanese consumers¡¦ interest. The products and stores are not attractive or follow the fashion trend. The promotion also did not appeal the consumers. The complexities of Taiwanese consumers¡¦ perspective toward M&S brand and country-of-origin, cultural differences and the potential reasons of M&S exited Taiwan are as well emphasized.
