Recent years have seen the emergence of accounts of the origins of the Disorganized attachment relationship in early mother–infant interaction, each building on the pioneering work of Main and Hesse—dysfunctional emotional processes figure prominently in all these accounts. This paper applies a framework based on two complementary theories of emotion socialization, Gianino and Tronick's (1992 ) Mutual Regulation Model and Gergely and Watson's (1996 ) Social Biofeedback Theory, to suggest an emotion‐based mechanism consistent with recently proposed models of the development of Disorganized attachment. The framework is used to generate hypothetical accounts of the role of dysfunctional emotional processes and maladaptive emotion socialization in early mother–infant interaction in the development of Disorganized attachment along two distinct pathways, one associated with actual abuse of the infant and the other associated with maternal unresolved trauma.  相似文献

Mercury contamination of aquatic ecosystems is a global environmental concern. Bioaccumulation of mercury in fish exposes consumers to risk. We interviewed ice anglers on Monona Bay, Wisconsin during the 2001-2002 ice fishing season to determine risk associated with fish consumption and methyl mercury (MeHg) intake. The majority of anglers (95%) were not at risk of mercury toxicity because they ate less fish than would be required to create health problems. The remaining 5% of ice anglers barely exceeded the mercury toxicity threshold, with the exception of one angler who exceeded the threshold by 0.926 ppm. Anglers encountered were all male and predominantly Caucasian. Fish consumption by ice anglers was independent of awareness of consumption advisories, education, income, and age. This suggests that future awareness efforts should (1) identify groups of anglers most at risk and (2) create policies to effectively reach these audiences.  相似文献

Gene expression data analysis provides scientists with a wealth of information about gene relationships, particularly the identification of significantly differentially expressed genes. However, there is no consensus on the analysis technique that will solve the inherent multiplicity problem (thousands of genes to be tested) and yield a reasonable and statistically justifiable number of differentially expressed genes. We propose the Multiplicity-Adjusted Order Statistics Analysis (MAOSA) to identify differentially expressed genes while adjusting for the multiple testing. The multiplicity problem will be eased by performing a Bonferroni correction on a small number of effects, since the majority of genes are not differentially expressed.  相似文献

La présente étude sur les pharmaciens en milieu hospitalier démon-tre que, depuis 20 ans, ce que l'on qualifie de «perspectives d'avenir>> présentées par ce secteur en pleine expansion attire un nombre disproportionné de femmes, dont la plupart sont tenues à l'écart lorsqu'il s'agit d'avancement professionnel. Même si les détentrices de qualifications postbaccalauréats ont accédéà de meilleurs postes de premier échelon, elles ont néanmoins perdu l'avantage pendant la première décennie de leur carrière, ce qui correspond aux résultats de recherches préalables réalisées sur les professions non féminisées. Cette situation semble indiquer que ce sont des facteurs liés au sexe, et non à la productivité, qui influent de façon négative sur les per-sonnes qui sont en mesure d'accorder les avancements; de la même manière, au moment de l'embauche pour des postes de premier échelon, ce sont les qualifications plutôt que la productivité qui influent sur leurs décisions.
This study of hospital pharmacists shows that the "opportunity" presented by this rapidly-expanding field over the past 20 years differentially attracted women, most of whom became ghettoized in terms of career advancement. Those women who acquired post-baccalaureate educational credentials obtained better entry-level positions, but, consistent with previous research on less-feminized professions, lost this advantage over the first decade of their careers. The pattern of advancement suggests that gender-related factors serve as a "negative signal" to gatekeepers, irrespective of productivity, just as credentials serve as a signal or proxy for productivity in hiring for entry-level positions.  相似文献

Abstract

Healthy built environments place people and communities at the heart of urban planning, encouraging decision-making based on human health, well-being and environmental sustainability. This paper describes the development of a set of indicators to assist in this endeavour—by translating and linking the research evidence base with policy-makers and other practitioners. The paper describes how the indicators were chosen, contextualized and subsequently structured to maximize useability for urban planners and health professionals working together to improve community health and neighbourhood sustainability.  相似文献

The Duckworth–Lewis method is steadily becoming the standard approach for resetting targets in interrupted one-day cricket matches. In this paper we show that a modification of the Duckworth–Lewis resource table can be used to quantify the magnitude of a victory in one-day matches. This simple and direct application is particularly useful in breaking ties in tournament standings and in quantifying team strength.  相似文献

A mixture experiment involves combining two or more components in various proportions and collecting data on one or more responses. A linear mixture model may adequately represent the relationship between a response and mixture component proportions and be useful in screening the mixture components. The Scheffé and Cox parameterizations of the linear mixture model are commonly used for analyzing mixture experiment data. With the Scheffé parameterization, the fitted coefficient for a component is the predicted response at that pure component (i.e. single-component mixture). With the Cox parameterization, the fitted coefficient for a mixture component is the predicted difference in response at that pure component and at a pre-specified reference composition. This article presents a new component-slope parameterization, in which the fitted coefficient for a mixture component is the predicted slope of the linear response surface along the direction determined by that pure component and at a pre-specified reference composition. The component-slope, Scheffé, and Cox parameterizations of the linear mixture model are compared and their advantages and disadvantages are discussed.  相似文献
