This article is based on a pilot study that examines the effects of recent organizational and public policy changes on Canadian academics' work practices and academic culture. It explores the differences between the use of online technologies by women and male academics in managing these effects. It interprets the complex and often contradictory findings of the study through the lens of time theorization, and speculates about the broader cultural implications of academics' changing work practices, including the possibility of a gestalt shift in the identity of the university, less as a site of research and reflection on society and increasingly as a productive and efficient part of the economy.  相似文献

To characterize infant reactions to jealousy evocation, 94 6‐month‐olds and their mothers were videotaped in an episode where the mothers directed positive attention toward a lifelike doll, and in 2 contrasting interactions: face‐to‐face play and a still‐face perturbation. Cross‐context comparisons of affects and behaviors revealed that jealousy evocation responses were distinguished by diminished joy and heightened anger and intensity of negative emotionality, comparable to levels displayed during the still‐face episode; heightened sadness, with durations exceeding those displayed during still‐face exposure; and an approach response consisting of interest, looks at mother, and diminished distancing, which was more pronounced than that demonstrated during play. Infants' heightened anger and sadness during jealousy evocation correlated with heightened maternal sensitivity and dyadic vocal turn‐taking, respectively, during play; and infants' diminished joy and interest during jealousy evocation were associated with heightened maternal withdrawal and intrusiveness, respectively, during play. Both fear and mother‐directed gaze were greater in girls. The discussion argues for interpreting the infant's mixed and agitated reaction to jealousy evocation as evidence of jealousy.  相似文献

Summary This article reports on the first extensive survey of ApprovedSocial Worker (ASW) activity under the Mental Health (NorthernIreland) Order 1986. The integrated health and social servicesorganizational structure, the adverse effects on individualmental health of the legacy of thirty years of civil conflictand the move from hospital to community care are significantfeatures which have influenced the delivery of mental healthsocial work services locally. The practice and experience ofASWs was surveyed by postal questionnaire and user and carerexperience of compulsory hospital admission was investigatedby a series of focus groups. The study revealed that two-thirdsof ASWs had experience of acting as an applicant in compulsoryhospital admission during the past two years. Nearly half (42per cent) of these ASWs had reported experience of between oneand five admissions and one-tenth had completed over twentyadmissions in the two-year period. In only a small minorityof cases did joint face-to-face assessment with the GeneralPractitioner (doctor) take place; nearly half of ASWs reporteddifficulties in obtaining transport; and only one-fifth of ASWshad experience of acting as a second approved social worker.Half of ASWs reported experience of guardianship, either asapplicant or in making the recommendation. Both service usersand carers reported a lack of understanding about the role ofthe ASW and complained about the lack of alternative resourcesthat ASWs could use to prevent hospital admissions. These findingsare discussed and a number of recommendations are proposed forimprovements to approved social worker practice.  相似文献

Risk Assessment for Invasive Species   总被引:10,自引:0,他引:10  
Although estimates vary, there is a broad agreement that invasive species impose major costs on the U.S. economy, as well as posing risks to nonmarket environmental goods and services and to public health. The domestic effort to manage risks associated with invasive species is coordinated by the National Invasive Species Council (NISC), which is charged with developing a science-based process to evaluate risks associated with the introduction and spread of invasive species. Various international agreements have also elevated invasive species issues onto the international policy agenda. The World Trade Organization (WTO) Sanitary and Phytosanitary (SPS) Agreement establishes rights and obligations to adhere to the discipline of scientific risk assessment to ensure that SPS measures are applied only to the extent required to protect human, animal, and plant health, and do not constitute arbitrary or unjustifiable technical barriers to trade. Currently, however, the field of risk assessment for invasive species is in its infancy. Therefore, there is a pressing need to formulate scientifically sound methods and approaches in this emerging field, while acknowledging that the demand for situation-specific empirical evidence is likely to persistently outstrip supply. To begin addressing this need, the Society for Risk Analysis Ecological Risk Assessment Specialty Group and the Ecological Society of America Theoretical Ecology Section convened a joint workshop to provide independent scientific input into the formulation of methods and processes for risk assessment of invasive species to ensure that the analytic processes used domestically and internationally will be firmly rooted in sound scientific principles.  相似文献

Wilson's generalization of Arrow's impossibility theorem has been proved for the realm of private goods and economic preferences by Border and by Bordes and Le Breton. However, their proofs require the exclusion of the zero vector from the commodity space. This paper assumes continuity of social preference to obtain the impossibility theorem for the entire allocation space, even if the society is infinite. A simple corollary reveals that there is some individual who is assigned the zero consumption vector at every social optimum whenever the social welfare function is nonnull and nonimposed, and satisfies Arrow's independence axiom and continuity and transitivity of social preference.Financial support from the Social Sciences and Humanities Research Council is gratefully acknowledged, as are the suggestions of Charles Plott and an anonymous referee. The author assumes responsibility for any errors.  相似文献

Objective. Research demonstrates that nonwhite, lower‐income households bear the Georgia Lottery's tax burden, yet receive fewer benefits. However, local disparities in grading standards may mitigate the observed income redistribution. Our objective is to determine whether certain localities obtain more HOPE scholarships than expected, mitigating the observed redistribution. Method. We use fixed‐effects regression and a sample of Georgia's counties (1996–2002). Results. Our results indicate that some localities obtain more HOPE scholarships than expected, mitigating the observed redistribution. Conclusions. We conclude the income‐redistribution research result does not reveal a complete picture because it overlooks the HOPE scholarship's extraordinary allocation mechanism.  相似文献

This research examined adolescents' gender identity in relation to the peer context and their self‐concept. Participants were 229 adolescents who completed questionnaire measures of self‐concept and multidimensional gender identity. Regression analysis indicated peer acceptance partially mediated the relation between self‐perceived gender typicality and self‐worth. Cluster analysis revealed four groups of adolescents with differing profiles of self‐perceived gender typicality, felt peer pressure for gender conformity, and peer acceptance. Findings highlight the inherently social and contextual nature of gender identity. Also, the pathologizing of gender‐nonconforming youth is discussed.  相似文献

This study examined positive and negative outcome expectancies for risk behaviors, and their association with engagement in risk behaviors, in a sample of 149 maltreated adolescents. “Outcome Expectancies” are evaluative social cognitions about what will occur as a consequence of one's actions. Risk behaviors and outcome expectancies for substance use, sexual behavior, and delinquency were assessed. In all regression models, positive expectancies were significantly related to risk behaviors while negative expectancies, with one exception, were not significantly related. In three of four regression models, significant interactions were found between positive and negative expectancies in predicting risk behaviors. The nature of the interaction differed by type of risk behavior. Beyond demonstrating associations between outcome expectancies and risk behaviors in a maltreated sample, this paper contributes to the study of social information processing by demonstrating significant interactions between positive and negative expectancies.  相似文献
