Poverty and income inequality undermine women's health in a myriad of ways. This article discusses findings from the Full Plate Project, which addressed women's experience of food security, obesity, and chronic disease in Atlantic Canada. Through first-hand accounts, it identifies a vicious cycle surrounding the food insecurity–obesity paradox. The cycle's core elements included experiences of poverty, food insecurity and nutritional deprivation, weight gain leading to obesity, stress, and experiences of chronic illness. These mainly qualitative findings provide a vivid and multi-layered analysis of the effects of inequalities on health. A majority of Full Plate participants were lone mothers and unattached women, and existing outside of a two-adult member household framework. The vicious cycles experienced are intertwined and cannot be addressed by compartmentalising elements of health or social services. Evidence indicates that policies must respond fully to the social determinants of health and multiple inequalities related to poverty, gender, age, mobility, disability, location, culture, coping skills, and other dynamics. 相似文献

Michael Johnson's differentiation of “types” of domestic violence has had a significant impact on courts and providers, in part because of its claim to an empirical basis. Unfortunately, the label “situational couple violence” has already been used by judges and evaluators to minimize abuse claims in custody cases. Johnson's repeated assertion that SCV is the most common form of domestic violence reinforces the marginalizing of domestic violence. But what do his data actually show? Here Professor Meier takes a close look at the research Johnson relies on and finds that it fails to prove his thesis. Rather, the data suggest that Johnson has it exactly backward: Control-based abuse is probably far more common than “situational” domestic violence. 相似文献

In regenerative simulation, one frequently requires an estimate or a confidence interval for the ratio of the means of the two components of a certain bivariate random quantity. Estimation of this ratio has been studied by many authors and most recently by Asmussen and Rydén(2010). Here, we propose an estimate that performs better than the best of the known estimates. Our estimate is also lot simpler than the best known estimate. 相似文献

Infants in laboratory settings look longer at events that violate their expectations, learn better about objects that behave unexpectedly, and match utterances to the objects that likely elicited them. The paradigms revealing these behaviors have become cornerstones of research on preverbal cognition. However, little is known about whether these canonical behaviors are observed outside laboratory settings. Here, we describe a series of online protocols that replicate classic laboratory findings, detailing our methods throughout. In Experiment 1a, 15-month-old infants (N = 24) looked longer at an online support event culminating in an Unexpected outcome (i.e., appearing to defy gravity) than an Expected outcome. Infants did not, however, show the same success with an online solidity event. In Experiment 1b, 15-month-old infants (N = 24) showed surprise-induced learning following online events—they were better able to learn a novel object's label when the object had behaved unexpectedly compared to when it behaved expectedly. Finally, in Experiment 2, 16-month-old infants (N = 20) who heard a valenced utterance (“Yum!”) showed preferential looking to the object most likely to have generated that utterance. Together, these results suggest that, with some adjustments, online testing is a feasible and promising approach for infant cognition research. 相似文献

IntroductionThis study seeks to explore midwives’ perceptions about childbirth and in particular their beliefs about normality and risk. In the current climate of increasing interventions during labour, it is important to understand the thought processes that impact on midwifery care in order to examine whether these beliefs influence midwifery clinical decision-making.Method12 Midwives who worked in a variety of metropolitan hospitals in Sydney, Australia were interviewed about how they care for women during labour. The study utilised an inductive qualitative design using photo elicitation during the interview process.ResultsSix themes emerged from the data that clearly indicated midwives felt challenged by working in a system dominated by an obstetric model of care that undermined midwifery autonomy in maintaining normal birth. These themes were: desiring normal, scanning the environment, constructing the context, navigating the way, relinquishing desire and reflecting on reality. Most midwives felt they were unable to practice in the manner they were philosophically aligned to, that is, promoting normal birth, as the medical model restricted their practice.DiscussionThe polarised views of childbirth held by midwives and obstetricians do little to enhance normal birth outcomes. Midwives in this study expressed frustration that they were unable to practice midwifery in a way that reflected their belief in normal birth. This, they cite is a result of the oppressive obstetric model prevalent in maternity care facilities in Sydney and the over use of technological interventions during childbirth. 相似文献
