Abstract Women's contributions to the farm and farm household have historically been undervalued. An analysis of farm magazine “success” stories through six decades indicates that these stories may be a vehicle for reproducing and transmitting a traditional domestic ideology that separates farm production from the rest of the farm household and that rarely portrays women as significant contributors to the economic well-being of either. Magazine stories depict women as spouses or farm helpers, but not as producers or decision-makers. Farm magazines thus offer few models of realistic gender relations for either farm women or farm men. 相似文献

Conflict frequently occurs between community members and environmental/public health officials when an unusual number of cancer cases is reported. This conflict may result from different ways in which laypeople and experts interpret facts to judge whether there is an environmental cause of the cancer cases, but little is known about this issue. Volunteer laypeople (N= 551) and epidemiologists (N= 105) read a hypothetical scenario about cases of cancer on one neighborhood block. Participants judged whether each of the 23 facts about the situation made it “much more likely” to “much less likely” that something in town was causing the cancer cases (7‐point scale). The facts were designed to be “alarming,”“reassuring,” or “neutral” (i.e., according to epidemiological principles, should increase, decrease, or have no impact on the likelihood of an environmental cause). The laypeople were alarmed by most of the facts (mean response significantly greater than the scale midpoint), including all of the neutral facts and over half of the reassuring facts. The experts were more balanced: they were alarmed by none of the neutral or reassuring facts. Their responses showed significantly less alarm than the laypeople's responses (p < 0.0001 for all comparisons). This study reveals that laypeople are not reassured by information that substantially lowers the chance of an environmental cause for cancer cases. Lay responses differ significantly and systematically from experts who are far less alarmed by relevant facts. These findings may help explain the conflicts between the two groups in situations where concern about cases of cancer arises in a community. 相似文献

This study investigated the behaviour and communication of seven‐ to eight‐year‐old children during a dyadic computer task. The children participating were identified by peers as: (1) initiators of bullying (‘bullies’); (2) defenders of those victimised (‘defenders’); and (3) those who generally do not take on a consistent role in relation to bullying (‘non‐role’ children). Children were videotaped during the task and the interaction was coded, 34 dyads participated. Defenders used significantly higher levels of supportive communication such as explanation and guidance than bullies. The task performance of dyads consisting of defenders with non‐role children was significantly superior to that of dyads comprising bullies plus non‐role children. The behaviour of the non‐role children was influenced according to whether they were working with a bully, a defender or another non‐role child. The study suggests that the roles that children adopt in relation to bullying influence their behaviour in other, non‐bullying contexts. 相似文献

This study compares levels of physical activity of 9–14-year-old children from a self-reported time diary with those measured using an accelerometer. Children (N = 92) wore an accelerometer for one weekend day and completed a 24-hour time diary for that day. The time children spent in moderate to vigorous physical activity from time diaries was moderately highly correlated with the measured results. Self-reported and objective measures of intensity were correlated, but the correlation varied substantially by activity and characteristics of the family. This study provides empirical evidence to support the validity of time-diary estimates when accelerometer data are not available. 相似文献

The annual meeting of the Ohio Valley Group of Technical Services Librarians (OVGTSL) was held May 16–18, 2007, at the Holiday Inn-University Plaza in Bowling Green, Kentucky. One hundred twenty technical services librarians from Indiana, Ohio, Kentucky, and points beyond gathered for programming centered around the theme of “Mapping Our Way: New Formations in Technical Services.” 相似文献

The authors consider a special case of inference in the presence of nuisance parameters. They show that when the orthogonalized score function is a function of a statistic S, no Fisher information for the interest parameter is lost by using the marginal distribution of S rather than the full distribution of the observations. Therefore, no information for the interest parameter is recovered by conditioning on an ancillary statistic, and information will be lost by conditioning on an approximate ancillary statistic. This is the case for regular multivariate exponential families when the interest parameter is a subvector of the expectation parameter and the statistic is the maximum likelihood estimate of the interest parameter. Several examples are considered, including the 2 × 2 table. 相似文献

This paper explores the reasons why rural firms choose to adopt and use information and communications technologies. Evidence for rural restructuring and its implications for conceptualising the rural economy, is reviewed. Information on firms is obtained by means of a questionnaire survey and intensive in-depth interviews. Pronounced variations in adoption are identified. They are explained by the pressures exerted by customers and suppliers and the ways these are responded to by managers. The concept of a two-tier rural economy, based upon levels of adoption, is introduced. The need to focus upon global–local rather than urban–rural differences is emphasised. Implications for those who advise and seek to help rural businesses are considered. 相似文献
