Gender differences in occupational wage mobility in the 1958 cohort

This article examines the wage growth of British men and women between the ages of 33 and 42 who were employed full time at both of these ages using the 1958 National Child and Development Study. Wage growth is examined in the differences of the log of hourly wage rates reported at the 33 and 42 year old interviews of this cohort study. Men were found to have higher wage growth rewards than women when in higher occupations and be more likely than women to be in these higher wage growth occupations. Women's wages grew more slowly over the period than men's wages because they were located disproportionately in lower growth and feminized jobs. Domestic ties did not explain the differences in wage growth for this group, where the occupational penalties of gender widened. Copyright © 2008 BSA Publications Ltd

Market Signals Transmitted by Grid Pricing

Grid pricing improves the flow of information to producers, but market signals sent by grids may not be clearly understood. This study uses a two-stage Coefficients of Separate Determination process, four sets of fed cattle carcass data, and sensitivity analyses to identify market signals sent by grid pricing. Weight sends a stronger market signal than carcass quality characteristics such as quality and yield grade. Although grids are shaping production, market signals indicate that lower quality carcasses are penalized more than higher quality carcasses are rewarded. Sensitivity analyses suggest changes in quality and yield grade discounts have the greatest impact on market signals.beef cattle, Coefficients of Separate Determination, grid pricing, market signals, value-based marketing, Demand and Price Analysis,

Psychosexualism in Victorian Literature: A Psychoanalysis of Jane Eyre and Dracula

My thesis consists of historical facts and literary analysis and is made up of three chapters. In the first chapter, I look at two varying elements of psychosexualism, the emotional and the physical, and discuss how each can be applied to Jane Eyre and Dracula. The chapter also contains an explanation for the term psychosexualism and provides a brief history of: the Victorian notion of hysteria and spermatorrhea, the twentieth-century classifications of love and sex addiction, as well as the twenty-first-century to Histrionic Personality Disorder and Sexual Sadism Disorder. The second chapter provides an analysis of Jane Eyre, specifically looking at Edward Fairfax Rochester. This chapter also focuses on the evolution of Rochester’s disorder as seen throughout the centuries. The third chapter is an analysis of Dracula, specifically looking at how spermatorrhea, sex addiction, and sexual sadism disorder affect the characters of Johnathan Harker, Renfield and Dracula. The evolution of the physical element of psychosexualism between the three characters listed above makes up the connection to the previous chapters

Development Of A Personal Diet Plan Database Application For Persons With Severe Food Allergies

This project will research, analyze, design, and implement a computerized system that will assist patients in creating a personal diet plan based upon a rotation diet. This diet, specifically designed for patients with severe food allergies, requires that a patient may only eat a particular food every n days (where n is any number), and foods from the same biological food family every n days. Currently, patients use either pen-and-paper or a computerized spreadsheet to create weekly or monthly food meal plans for the diet plan. The meal plans are usually transferred by hand to their daily or weekly shopping lists. There are three main problems with the current system. First, many patients complain that in order to make their meal plans simple enough to follow easily, they tend to eat the same foods in the same order each week, so their diets have become very plain and uninteresting. Second, patients frequently make mistakes on their meal plans relating to which foods belong to a given food family, which defeats the purpose of the rotation diet plan. Finally, hand transferring the meal plans to shopping lists is time consuming and often inaccurate. The ultimate goal of this project is to create a computerized system that will assist patients to make up a personalized diet plan that allows them to enjoy a broader range of meals, and also to quickly and accurately make up shopping lists for the meals

The genetic and environmental basis for CHC biosynthesis in Drosophila

Cuticular hydrocarbons (CHCs) are produced by insects and primarily used to prevent desiccation. In Drosophila, certain compounds have secondary roles as infochemicals that may act during courtship to influence mate choice. Certain CHCs may stimulate courtship with heterospecifics or act to repel conspecifics. The CHC profile produced by an individual is the result of the interaction between its genetic background and the environment, though the genes that underlie species differences in CHC production and how the environment can modulate the abundance of individual compounds within a species is not well known. Here, candidate gene CG5946 was found to be involved in species differences in the production of 7,11-heptacosadiene and 7-tricosene in hybrids between D. melanogaster and D. simulans. In addition, diet, but not microbial content, was found to influence the proportion of long-chain CHCs produced by D. melanogaster. This study provides insight into the factors influencing CHC production in Drosophila

Delivering hot food on motorcycles: A mixed method study of the impact of business model on rider behaviour and safety

In Great Britain, motorcyclists have the highest fatality rate per billion passenger miles of all road users, and people who work on motorcyclists have a much greater risk of injury compared to other motorcyclists. Many hot meal delivery services are provided by people using motorcycles. Work can be accessed by an app or by being employed by a restaurant. There is a need to understand whether the business model under which riders work influences their experience of risk or whether this is just related to the risks of delivering food by motorbike per se. Interviews were conducted with six gig riders and 14 employed riders and an online survey was completed by 164 riders working via apps and 155 employed by restaurants. Gig workers were significantly more likely to agree that that their phone was a distraction and that they violated traffic laws related to speeding, red light running and, unsurprisingly, they had more points on their licence compared to employed riders. Gig riders were also more likely to be incentivised to ride in dangerous conditions and carry unstable loads. Gig workers were more likely to report being involved in collisions where their vehicle was damaged and where someone was injured. These findings were also evident in interview narratives. More needs to be done to make gig companies embed practices that do not increase risks for delivery riders

Risk Factors in the progression from tuberculosis infection to disease

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 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
