This study investigated attachment security and behavior in 34 physically disabled infants and 26 non‐disabled infants by using convergent, categorical (secure, avoidant and ambivalent) and continuous (Attachment Behavior Q‐Set) measures of the relationship, based on the same set of home observations. Proportions of attachment classifications were not different for disabled and non‐disabled infants, but insecure infants in the disabled group scored consistently lower on the AQS security score than non‐disabled insecure infants. This result suggests that while proportions of attachment classifications may not vary as a function of infant status, insecure disabled infants are more insecure than insecure non‐disabled infants. An analysis of 5 behavioral dimensions of the AQS showed that secure infants emitted the same kinds of attachment behaviors without regard for infant status. Insecure disabled infants, however, showed lower levels of secure base behavior and physical contact with mother than their non‐disabled counterparts, and showed a marginal tendency to fuss more as well. Discussion focuses on the potential benefits of using convergent, categorical and continuous measures of attachment in the study of both typical and atypical groups of infants. 相似文献

Human resource shortages require effective human resource management (HRM). Findings from research about ongoing labor shortages
in air traffic control (ATC) are used to build a preliminary theory of appropriate HRM responses. Our international sample
of major ATC agencies generally developed a set of best HRM practices to attract, motivate, and retain human assets. Key factors
included (1) cultural and institutional norms, (2) technological change, (3) union responses, and (4) organizational form
and structure (e.g., civil service versus commercial firms). While ATC’s rare human aptitudes, lengthy training to develop
firm-specific human capital, and lifelong employment may limit the preliminary theory’s general applicability, crucial lessons
emerge about human resource planning.
This research was conducted with the support of the Social Sciences and Humanities Research Council, the Rice Fellowship,
the Ziegler Fellowship, and the Center for International Business Studies at the University of Alberta. We are indebted to
the individuals interviewed. 相似文献

Converse's definition of ideological contraint is expanded to provide for various respondent identified ideological dimensions rather than an all encompassing liberal-conservative dimension. Using this redefinition a sample of adults is shown to have high levels of ideological constraint. Ideological constraint is shown to vary with the degree of cognitive complexity and the degree of preference evaluability. The latter is a new concept that suggests that some issues will be easier for a respondent to demonstrate constraint on depending upon the availability and applicability of preference criteria. Salience is also shown to have a positive relationship with ideological constraint, but only when preference evaluability is high. 相似文献

Much of the existing scholarly works portray institutional voids (IVs) in emerging economies as impeding forces against the development of new ventures. However, little attention has been paid to how such voids generate positive outcomes in emerging market new ventures. Drawing on the institutional theory, we propose IVs as crucial enablers of new venture internationalization. In addition, we investigate both how and when IVs enhance the degree to which new ventures internationalize by examining international learning effort (ILE) as a mediator and two domestic market environmental factors (i.e., environmental dynamism and competitive intensity) as important contingencies. We test our moderated mediation model using primary data gathered from 211 new ventures from Ghana. We found that ILE mediates the relationship between IVs and new venture internationalization and that both environmental dynamism and competitive intensity moderate the indirect relationship between home-country IVs and new venture internationalization. We discuss the theoretical and practical implications of this study. 相似文献

Federal and other regulatory agencies often use or claim to use a weight of evidence (WoE) approach in chemical evaluation. Their approaches to the use of WoE, however, differ significantly, rely heavily on subjective professional judgment, and merit improvement. We review uses of WoE approaches in key articles in the peer‐reviewed scientific literature, and find significant variations. We find that a hypothesis‐based WoE approach, developed by Lorenz Rhomberg et al., can provide a stronger scientific basis for chemical assessment while improving transparency and preserving the appropriate scope of professional judgment. Their approach, while still evolving, relies on the explicit specification of the hypothesized basis for using the information at hand to infer the ability of an agent to cause human health impacts or, more broadly, affect other endpoints of concern. We describe and endorse such a hypothesis‐based WoE approach to chemical evaluation. 相似文献
