Girls@Play     
This paper reports on findings from a three-year, Canadian federally funded research project entitled “Education, Gender and Gaming” in which we documented the play practices of girls and boys playing console-based games. We show, in particular, how many of the presumptions and assumptions about “girls playing games” simply do not hold over time, or given a particular context. We therefore attempt to show how our research practices and methodologies help to shape what we have thus far taken as “evidence” or “facts” about gender and illustrate how some of those presumptions might not necessarily hold over time or given different contexts.  相似文献

Concern about high infant mortality and its suspected connection with the lack of breast-feeding stimulated the collection of statistics about the frequency of breast-feeding in several German states during the late roth and early 20th centuries. Contrary to the assumption that universal and extended breast-feeding is customary among rural agricultural populations, large regional variations existed both in the proportion of children who were breast-fed and in the average duration of the period for which they were breast-fed. An analysis of these data in connection with statistics of infant mortality and marital fertility confirms the association between high infant mortality and the absence of breast-feeding. An hypothesis linking breast-feeding and fertility, however, is not confirmed. Marital fertility appears to be much more closely associated with infant mortality than with breast-feeding.  相似文献

This paper explores the relative importance of social factors and health measures in predicting educational achievement in early and late adolescence using population-based administrative data. The sample was made up of 41,943 children born in Manitoba, Canada between 1982 and 1989 and remaining in the province until age 18. Multilevel modeling nests each individual (level 1) within a family (level 2) residing within a neighborhood (level 3). Most important in predicting adolescent achievement were a broad socioeconomic status index (and a narrower measure of household income), being on social assistance, mother’s age at first birth, gender, residential mobility, the presence of ADHD/Conduct disorders, and measures of family functioning (child taken into care or offered protection services and family structure history). Family size, birth order, and newborn characteristics (birthweight, APGAR, gestational age) were statistically significant but of little importance in explaining the outcomes. Both examining regression coefficients and systematically omitting variables showed social factors (often emphasized by epidemiologists) to have markedly greater effects than the combination of health measures (often stressed by economists) in predicting achievement. However, mental health in childhood is identified as among the important predictors. Record linkage across population datasets from health, education, and family services ministries allowed: tracking health and educational attainment at different times in a child’s life, following a large number of cases across childhood, considerable sensitivity testing, controlling for unmeasured family and neighborhood effects, generating an extensive list of predictors, estimating effect sizes, and comparing Manitoba results with those of well-known American studies.  相似文献

The literature on happiness or subjective well-being has explored the determinants of happiness without taking into consideration the role that water plays. In this paper we attempt to draw attention to water in subjective well-being studies. Approximately one hundred million people do not have access to water. A lack of clean water causes diseases such as diarrhea and cholera, responsible for around 5% of the total deaths in the world. Access to water should therefore be a necessary asset in life. In order to consider access to water, we estimate its influence on subjective well-being using data from rural Yucatan, Mexico. Residents in Yucatan suffer from low quality access to water and there are also imperfections in the management of the service, such as water cuts. We estimate the influence of water on subjective well-being, finding a positive and significant relationship. In a second stage of the research, we relate water access variables to subjective well-being, the health and the water domain of life, finding significant results. These results make it possible to formulate political measures concerning access to water and happiness maximization. We demonstrate that access to water is important for well-being in Yucatan and might be important in many other places; we therefore encourage future research to contemplate water satisfaction and water variables in their analysis.  相似文献

Abstract

Universal services focus on prevention and providing the support to parents that will help them meet the challenges of parenthood and deal with problems before they become entrenched. Many countries now have good universal services available for new families, and significant advances have been made in recent years to recognize the importance of the early years in the optimal development of the child. This article is based on a qualitative study of transition to parenthood. The study explored the experience of 25 first-time mothers in socioeconomically diverse circumstances in New Zealand. Eleven partners of these women also participated. Mothers were interviewed three times, first in late pregnancy, then 3 and 12?months after giving birth. Partners were interviewed once, mid-way through the baby’s first year. The article focuses on how participants experienced service support. It illustrates some of the diverse needs of new parents, and explains ways in which prevention services might become more responsive to parents’ expressed needs. The authors offer a case for stronger interplay between universal services and informal systems of support, and the development of a new generation of universal services that act as enablers of natural support hubs for new families within their own communities.  相似文献

Seaports are introduction hotspots for invasive alien species (IAS). This is especially true for rodents, which have accompanied humans around the globe since the earliest days of ocean-going voyages. The rapid spread of IAS soon after arrival in a new environment is facilitated by further human-mediated transport or landscape features, like roads. By measuring genetic diversity and structure to investigate dispersal pathways, we gained insight into the transport, spread and establishment stages of a biological invasion, leveraging the most common rodent species (R. norvegicus) in this setting. We characterized the genetic structure of three Norway rat populations along a busy industrial road used by trucks to access the Port area in Paranaguá city (Brazil). A total of 71 rats were genotyped using 11 microsatellite markers. The results revealed a pattern of gene flow contrary to the expected stepping-stone model along the linear transect, with the two furthest apart populations being clustered together. We hypothesize that the observed outcome is explained by natural dispersal along the corridor being lower than human-mediated transport. The sampled area furthest from the port is a gas station frequented by trucks which are considered the most likely mode of transportation. In terms of management strategies, we suggest more emphasis should be put on cargo surveillance to lower the risk of Norway rat dispersal, not only for biosecurity, but also for sanitary reasons, as this port is a major grain trading point.

This cross-sectional questionnaire study presents a multi-level analysis on 2565 workers in 188 departments in 36 organizations in the Netherlands. A three-level model is used in which individual workers are nested within departments, which in turn are nested within organizations. Research questions concern (1) the amount and distribution of variance in job-related stress explained for the three levels in the study (individuals, departments, organizations), and (2) the specificity of relationships between psychosocial job demands and job-related stress in the three-level model. Well-being showed slightly more raw variance to be explained at supra-individual levels than strain. The full regression model explained about 35% of the total variance in both work-related strain and well-being. Psychosocial job conditions did not exceed the expected amount of 10 to 15% contribution to this explained variance. These results do not differ from comparable studies that do not use multi-level analysis. The variance distribution in the full model, however, showed unexplained variance to be located at the individual level for both strain and well-being, and at the departmental level only for well-being. This last finding shows a direction for possible improvement of work stress models. Specificity of relationships was also shown: psychological job demands were more strongly related to strain, whereas job content variables (i.e. job variety, job control) were more strongly related to well-being. Results also suggested that social support was more strongly associated with well-being than with strain. Well-being appeared to have a more widely varying range of predictors than strain.  相似文献

This article investigates the ways sexual violence experienced on college campuses in the United States is situated within the neoliberal university. Feminist theories are utilized to explore the relationship between sexual violence and neoliberal ideologies. The authors evaluate how neoliberal tenets imbedded in higher education have contributed to, and exacerbated, an environment where sexual victimization is common. An institutional level of analysis is utilized to examine the neoliberal influence on campus sexual violence and investigate the utility of the term everyday terrorism. The authors also address “crimes of omission”, institutional betrayal, and the significance of institutional bravery/courage. The authors provide recommendations for future research in the areas of everyday terrorism and campus violence.  相似文献
