On the basis of discussion and analysis during and following an ATSDR science panel on the bioavailability of mercury in soils, it is apparent that the default assumption of 100% relative bioavailability for mercury-contaminated soils is excessively conservative. However, current knowledge does not allow the development of default assumptions or guidelines for determining relative bioavailability of mercury in soils. Until such default assumptions or guidelines can be developed, site-specific assays of bioavailability, preferably using either animal bioassays or validated in vitro techniques, may provide the best approach for estimating soil-mercury bioavailability. 相似文献

In this research case study, the competing hypothesis of socialization, structural and social role theories were derived and used to explore and compare the job attitudes and satisfaction of women and men in a Canadian insurance company subsequent to voluntary implementation of an employment equity programme. Gender comparisons of both managerial and clerical employees on individual facets of satisfaction indicated the most support for social role theory, some support for structural theory and the least support for socialization theory. These findings indicate that managerial women and men tend to derive work satisfaction from similar sources. The variation in facet results cautions against global conclusions about gender and job satisfaction. Unanticipated consequences such as a 'backlash' (Faludi, 1991) of managerial men and a 'glass escalator' (Williams, 1992) for clerical men were also suggested by the findings in this case. A key implication is the potential benefit to both organizations and managerial women from steps taken to level the structural playing field. 相似文献

The impact and management of cognitive gap in high performance product development organizations 总被引:1,自引:0,他引:1
Kathryn W. Jablokow David E. Booth 《Journal of Engineering and Technology Management》2006,23(4):313-336
The close alignment of applied research and development units with manufacturing operational structures can provide excellent opportunities for maintaining robust product pipelines and reducing product development cycle times. Within such an integrated organizational model (IOM), however, lies a potentially disruptive psychological mechanism that can lead to the dissolution of this delicate partnership if it is not handled properly. This mechanism is cognitive gap, which can take several basic forms: first, as differences between the nature and difficulty of the problem at hand and the cognitive resources of the problem solvers tasked with its solution; and second, as differences between the cognitive abilities and approaches of the problem solvers themselves. In this paper, we define and discuss cognitive gap within the context of Kirton's Adaption-Innovation theory, a useful framework for understanding problem solving (and problem solvers) in general. Specific implications (both favourable and potentially destructive) of cognitive gaps for high performance product development organizations are discussed, and suggestions for their effective management are offered. 相似文献

The Web proxy location problem in general networks is an NP-hard problem. In this paper, we study the problem in networks showing a general tree of rings topology. We improve the results of the tree case in literature and get an exact algorithm with time complexity O(nhk), where n is the number of nodes in the tree, h is the height of the tree (the server is in the root of the tree), and k is the number of web proxies to be placed in the net. For the case of networks with a general tree of rings topology we present an exact algorithm with O(kn

Local Governments Connecting to the Global Economy: Globalization as Catalyst in Governance of East African Cities 总被引:1,自引:0,他引:1
Eric E. Otenyo 《Public Organization Review》2004,4(4):339-360
This article responds to two questions: first, how are large local governments in East Africa responding to the emerging global economy? Second, is globalization a catalyst in enhancing local governance in Nairobi, Kampala, and Dar es Salaam? The paper is an empirical analysis of strategies adopted by local government organizations in search of meeting challenges brought by a globalization. While there are some similarities in the strategies and processes adopted, the implementation pace varies across the three organizations. At the end, an attempt is made to explain these differences. 相似文献

Internalized Other Interviewing in Relational Therapy: Three Discursive Approaches to Understanding its Use and Outcomes 下载免费PDF全文

For over 20 years, family therapist Karl Tomm has been engaging families and couples with a therapeutic intervention he calls Internalized Other Interviewing (IOI). The IOI (cf. Emmerson‐Whyte, 2010; Hurley, 2006) entails interviewing clients, from the personal experiences of partners and family members as an internalized other. The IOI is based on the idea that through dialogues over time, one can internalize a sense of one's conversational partner responsiveness in reliably anticipated ways. Anyone who has thought in a conversation with a family member or partner, “Oh there s/he goes again,” or anticipates next words before they leave the other's mouth, has a sense of what we are calling an internalized other. For Tomm, the internalized anticipations partners and family members may have offers entry points into new dialogues with therapeutic potential—particularly, when their actual dialogues get stuck in dispreferred patterns. 相似文献

Australia and the United Kingdom have mandatory systems of case reviews, which are conducted whenever a child known to welfare or health services has died or been seriously harmed due to maltreatment. In the United Kingdom those conducting case reviews are required to involve family members in their deliberations. This study employed discourse analysis to examine the representation of family voices in 41 Overview Reports of Serious Case Reviews undertaken in England and published during 2014. The findings revealed that the contributions of family members were generally relegated or their legitimacy undercut by the positivist framing of most overview reports. However, the research also identified how the framing of family contributions within an interpretivist paradigm could engender highly complex understanding of deficiencies in child protection systems and lead to crucial new learning for professionals. 相似文献

Peer sociometrics and teachers' friendship reports were compared in 2179 preschool dyads. One hundred twenty of 306 reciprocated friend dyads from peer sociometric data were also identified as good friends by their classroom teachers, and 301 of 600 of non‐reciprocated dyads in peer data were named as friends by one or both classroom teachers (overall kappa = .16). Friendship classifications from both peer and teacher data had significant relations with variables relevant to peer interactions, social skills, peer acceptance, and teacher‐rated scales (six of seven tests significant for peer data; five of eight significant for teacher data). Multilevel analyses indicated that friendship status effects were not qualified by classroom‐level differences. Findings suggest that sociometric tasks can identify preschoolers' peer friendships and that the range of correlates may be broader in peer‐choice data than in teachers' friendship evaluations. 相似文献

Previous scholarship has demonstrated the importance of individual characteristics and structural context for understanding social capital formation. However, a developmental approach to social capital formation has, so far, been absent. In this study, I argue that social capital formation must be understood intergenerationally as well as structurally. Using hierarchical linear modeling, I investigate the hypothesized intergenerational transmission of social capital using Waves 1 and 2 of the National Longitudinal Study of Adolescent Health. The results show that, in addition to individual characteristics, neighborhood‐level factors, and school‐level variables, parental social capital is an important predictor of adolescent social capital. This study also suggests that the intergenerational transmission of social capital functions, in part, through family structure and that structural differences account for only a relatively small share of the variation in adolescent social capital. Potential explanations for these findings are discussed. 相似文献
