ABSTRACTThis article provides an extended case example highlighting the value of a supportive approach to practice, in addition to the importance of holding a psychodynamic developmental frame of reference. Concepts of repetition compulsion, the holding environment, and object constancy are applied to the clinical material. The case is underscored for its value as a teaching tool. 相似文献

This is an evaluative study on the delivery of devolved programs in health, agriculture and social welfare. It aimed to identify the major devolved programs/projects implemented by the LGU of Columbio, Sultan Kudarat; the responsiveness of the actual delivery of devolve services in terms of human resources, facilities and fund allocation; the status of devolve services implemented if it was effective and efficient; and the inadequacies encountered. The “expose facto” method of research was used. There were 49 implementers and 132 beneficiaries of the various devolved programs. There were 181 total respondents. A four-part questionnaire was constructed and the gathered data were supplemented by information extracted through interviews with Key Informants, Focus Group Discussions and document analysis. There were three departments implementing the devolved social services programs such as the Municipal Health Office with 6 devolved health programs; the Municipal Agriculturist Office with 6 devolved agricultural projects; and the Municipal Social Welfare and Development Office with 7 devolved social welfare programs. The respondents rated the implementation of devolve services in health, agriculture and social welfare programs between rank 5 to 9 for the aspects of human resources, facilities and fund allocations. The respondents assessed the implementation of devolved programs as Very Efficient and Most Responsive programs to the needs of the people specially the children, youths and women. The study also found some inadequacies observed during the implementation of devolved social services programs which were Agreed by the majority of the respondents. These findings implied that the implementation of various devolved social services for several years has made a significant difference in the lives of the people of the Municipality of Columbio, Sultan Kudarat, the Local Government of Columbio and program implementers with their commitment and solidarity to serve the people especially the marginalized is a manifestation of their unselfish dedication to uplift the socio-economic condition and well-being of the people. Hence, continuing projects should further be strengthened and supported to ensure the sustainability of the projects even if the support of different institutions has been terminated. 相似文献

To test the hypothesis that social engagement is a foundational aspect of other peer social competence indicators during early childhood, 160 Portuguese preschool children (“3‐year‐olds”) were observed at least in two different school years, using a battery of validated social competence assessments based on direct observations and child interviews. Multilevel growth models tested whether social engagement predicted initial values and linear changes in the other social competence indicators. Results were consistent with the hypothesis, insofar as both initial values and changes in social engagement significantly predicted initial values and changes in other social competence indicators. Additionally, the number of children's reciprocated friendships was also predicted by social engagement. These results are discussed from the perspectives of conceptual frameworks that consider individual differences in social competence during early childhood as a consequence of attachment histories and/or emotional competence. 相似文献

This article examines the effect of product development restructuring (PDR) on shareholder value. The results are based on a sample of 165 announcements made during 2002–2011. PDR announcements are associated with an economically and statistically significant positive stock market reaction. Over a two‐day period (the day of the announcement and the day preceding the announcement), the mean (median) market reaction is 1.63% (0.87%). The market reaction is generally positive regardless of the PDR purpose or action. Although the market reaction is more positive for higher R&D intensity firms, it is not directly affected by the firm's prior financial performance or whether the firm's primary PDR objective is to increase revenues or cut costs. However, the interaction between the firm's prior financial performance and its primary PDR objective is significant. For firms that are financial outperformers, the market reaction is more positive if the firm's primary PDR objective is to increase revenues. For financial underperformers, the market reaction is more positive if the firm's primary PDR objective is to cut costs. 相似文献

The current contribution extends theorizing on leadership and the exploration–exploitation dilemma using an evolutionary perspective. A theoretical connection is made between the exploration–exploitation dilemma and age-biased leadership preferences for exploratory change versus stable exploitation. For the majority of human evolution our species was semi- or entirely nomadic and the trade-off between exploration versus exploitation had substantial physical- and experience-based requirements which align with leadership opportunities as moderated by age. Thus, given the consistency and importance of correctly assigning leadership for the exploration–exploitation dilemma, human evolution has likely selected for age-biased leadership endorsement. Across three experiments we find that younger-looking leaders are endorsed for times of exploratory change and older-looking leaders for stable exploitation. Further, our results indicated that older leaders are endorsed for leading conservative exploitation of nonrenewable resources and younger leaders for exploration of renewable alternatives (i.e., green leadership). The results introduce an age-biased leadership endorsement hypothesis. 相似文献

This study assesses the combined impact of multiple certifications (i.e. ISO 9001, ISO 14001, OHSAS 18001) on perceived performance dimensions related to quality, environmental and occupational health and safety. Using survey data collected from 59 Irish manufacturing plants in 2014, we employed MANCOVA and regression analysis to test our proposed hypothesis. The results suggest that companies that are simultaneously ISO 9001, ISO 14001 and OHSAS 18001 certified are significantly better performers with regard to environmental and occupational health and safety compared to companies without multiple certifications. However, from a perceived quality performance perspective, having these multiple certifications doesn’t seem to be an effective performance improvement tool. 相似文献

We present an evolutionary perspective on charismatic leadership, arguing that charisma has evolved as a credible signal of a person's ability to solve a coordination challenge requiring urgent collective action from group members. We suggest that a better understanding of charisma's evolutionary and biological origins and functions can provide a broader perspective in which to situate current debates surrounding the utility and validity of charismatic leadership as a construct in the social sciences. We outline several key challenges which have shaped our followership psychology, and argue that the benefits of successful coordination in ancestral environments has led to the evolution of context-dependent psychological mechanisms which are especially attuned to cues and signals of outstanding personal leadership qualities. We elaborate on several implications of this signaling hypothesis of charismatic leadership, including opportunities for deception (dishonest signaling) and for large-scale coordination. 相似文献

Perceptions of infectious diseases are important predictors of whether people engage in disease‐specific preventive behaviors. Having accurate beliefs about a given infectious disease has been found to be a necessary condition for engaging in appropriate preventive behaviors during an infectious disease outbreak, while endorsing conspiracy beliefs can inhibit preventive behaviors. Despite their seemingly opposing natures, knowledge and conspiracy beliefs may share some of the same psychological motivations, including a relationship with perceived risk and self‐efficacy (i.e., control). The 2015–2016 Zika epidemic provided an opportunity to explore this. The current research provides some exploratory tests of this topic derived from two studies with similar measures, but different primary outcomes: one study that included knowledge of Zika as a key outcome and one that included conspiracy beliefs about Zika as a key outcome. Both studies involved cross‐sectional data collections that occurred during the same two periods of the Zika outbreak: one data collection prior to the first cases of local Zika transmission in the United States (March–May 2016) and one just after the first cases of local transmission (July–August). Using ordinal logistic and linear regression analyses of data from two time points in both studies, the authors show an increase in relationship strength between greater perceived risk and self‐efficacy with both increased knowledge and increased conspiracy beliefs after local Zika transmission in the United States. Although these results highlight that similar psychological motivations may lead to Zika knowledge and conspiracy beliefs, there was a divergence in demographic association. 相似文献
