Evidence from both clinical reports and empirical research suggests that symbolic play may help heal children’s traumas. Playfulness, an enduring individual characteristic, also contributes to resilience. However, trauma often sabotages children’s ability to engage in imaginary play and parents’ ability to be involved in playful interactions with their young children. This paper describes an innovative preventive group-intervention program by the name of NAMAL (Hebrew acronym for Let’s Make Room for Play), designed for mothers and their toddlers who live under the chronic stress of recurrent missile attacks in Israel. The major objective of the program is to bolster children’s resilience by enhancing their playful interactions with their mothers. The theme and activities of each session are organized around a saying with a relational or developmental message. Reports collected from 70 mothers after their participation in the program highlighted the success of the intervention and the changes in the children and parents, as well as in their interactions with each other. Follow-up interviews conducted a year after the intervention provided further information on the long-term positive effects of the program.  相似文献

This paper develops a model which explains breadth and depth of firms’ demand for employee voice. The theory innovation is to model employee voice as a factor input in production and derive a voice demand curve. Differences in voice productivity determinants across firms act as shift factors and cause cross-section variation in voice demand curves which translates into an empirically observable voice frequency distribution. Insights from institutional economics are incorporated to show that transition from a nonunion to union form of voice may cause a large discontinuity in the demand curve. Other contributions include: sharpened definition and delineation of the employee voice construct, use of the voice frequency distribution as a dependent variable in empirical research, graphical representation of the firm’s benefit-cost choice of voice, distinction between employee voice as communication and influence (muscle) and graphical demonstration of conditions under which one is preferred to the other, clarification of the participation/representation gap concept, and policy insights regarding pros and cons of the regulation of employee voice in American labor law.  相似文献

This paper examines year‐on‐year changes to the composition of performance peer groups used for relative performance evaluation in setting CEO pay in FTSE 100 companies and finds evidence of peer selection bias. The authors find that firms keep their peer groups weak by excluding relatively stronger performing peers. They also show that peer selection bias is less pronounced in firms with higher institutional investor ownership, which suggests that institutional investors might be aware of the risks of peer selection bias. The results suggest that peer group modifications can be viewed, at least in part, as an expression of managerial rent‐seeking.  相似文献

This paper examines task, relationship, and overload stress orientations of people in the high-context cultures of Russia and in the low-context cultures of Germany based on their government work experience. A Two-way ANOVA methodology is used for hypotheses testing in this research. As a result of the comparative, cross-national analysis of 462 responses, some significant differences were found between the two samples. Russians have higher scores on task and relationship orientations than German respondents. There is a marginally significant difference in the task scores between respondents who have government experience and those who do not. Respondents who have government experience are more task-oriented and experience more stress than those who do not have government experience. Finding reveals significant interaction between government experience and country in the task scores. Literature on German and Russian cultures is presented along with practical applications, suggestions, and implications for future studies.  相似文献

In some organizations, the hiring lead time is often long due to responding to human resource requirements associated with technical and security constrains. Thus, the human resource departments in these organizations are pretty interested in forecasting employee turnover since a good prediction of employee turnover could help the organizations to minimize the costs and impacts from the turnover on the operational capabilities and the budget. This study aims to enhance the ability to forecast employee turnover with or without considering the impact of economic indicators. Various time series modelling techniques were used to identify optimal models for effective employee turnover prediction. More than 11-years of monthly turnover data were used to build and validate the proposed models. Compared with other models, a dynamic regression model with additive trend, seasonality, interventions, and a very important economic indicator effectively predicted the turnover with training R2?=?0.77 and holdout R2?=?0.59. The forecasting performance of optimal models confirms that time series modelling approach has the ability to predict employee turnover for the specific scenario observed in our analysis.  相似文献

Scientism is an attempt to apply the methods and approach of the natural sciences to matters of human social and political concern. Scientism‐based discourse has been used to reframe the public debate about controversial science and technology into a risk assessment carried out by experts. The biotechnology industry has used a scientism‐based discourse to avoid regulation and labeling, claiming that the scientific makeup of their products is all that matters for governing regulatory policy, not their social, economic, or environmental impact. In this case study I examine the discourse used in support of and opposition to AquaAdvantage salmon, the first genetically engineered animal approved for human consumption. This case inspired an opposition coalition of consumer and environmental groups that led the FDA to organize a public meeting about its review of the fish. The analysis finds support for previous studies showing that regulatory debates over biotechnology in the United States are dominated by scientism, and that scientism generates public skepticism rather than confidence. In previous cases citizen groups were unable to challenge the authority of scientism‐based regulatory policy, but in this case the agency's decision not to require labeling was overruled by a congressional labeling mandate driven by citizen mobilization.  相似文献

Paternal involvement and acceptance were compared among 218 custodial fathers, 222 married fathers, and 105 divorced noncustodial fathers. Findings show that the custodial fathers were more involved with their children, coordinated less with their children’s mother, and viewed their children as more difficult than the other fathers. Two regression analyses were conducted. One revealed that greater paternal involvement was predicted by greater self-differentiation, greater sense of having received care from one’s own father, and a less avoidant caregiving disposition. The other showed that greater paternal acceptance was predicted by greater self-differentiation, greater sense of having received care from one’s own father, and a less anxious caregiving disposition. Finally, the findings show that coparenting, social support, and sense of the child as difficult moderated the associations between the fathers’ personal variables and their involvement, but not their acceptance.  相似文献

Society has a negative attitude toward people with intellectual disabilities or psychiatric disabilities. It is well documented that they are subjected to prejudice, stigma, and negative attitudes (Di Giulio, 2003 ; Finger, 1994 ). Professional literature indicates that information about disabilities and encounters with persons with disabilities can change negative attitudes (Carter, Hughes, Copeland, & Breen, 2001 ; Krajewski & Flaherty, 2000 ). This study accompanied 164 9th-grade students from various junior high schools throughout Israel. Half of the students participated in an integration program for changing attitudes toward persons with disabilities, and the other half served as the control group. The research examined the existence and the degree of relationship between participation in the program, changes in attitudes toward people with disabilities, and self-image. The research findings pointed to a positive change in attitudes of the participants of the program in comparison with the control group, resulting mainly from personal contact with people with disabilities. No relationship was found between levels of self-image of the research group and attitudes toward people with disabilities.  相似文献

Theories and traditions emphasizing the centrality of caring have guided the evolution of the healthcare professions. In contemporary practice, creating a therapeutic context in which healing can occur relies not just on the caring dispositions of individual clinicians, but also on the collective relational capacities of interprofessional healthcare teams. This article describes the intersection and complementarity of relational and interprofessional learning approaches to health education, provides exemplars of shared learning models and discusses the benefits and obstacles to integrating relational and interprofessional philosophies into real world practice.  相似文献

Well-designed office workspaces require good anthropometric data in order to accommodate variability in the worker population. The recent obesity epidemic carries with it a number of anthropometric changes that have significant impact on design. We examine anthropometric change among US civilians over the last 50 years, and then examine that change in a subset of the US population--the US military--as military data sets often have more ergonomic dimensions than civilian ones. The civilian mean stature increased throughout the period 1962 to 2006 for both males and females. However, the rate of increase in mean weight was considerably faster. As a result, the male obesity rate changed from 10.7% in 1962 to 31.3% in 2006. The female change for the same period was 15.8% to 33.2%. In the Army, the proportion of obesity increased from 3.6% to 20.9%, in males. In the absence of national US ergonomic data, we demonstrate one approach to tracking civilian change in these dimensions, applying military height/weight regression equations to the civilian population estimates. This approach is useful for population monitoring but is not suitable for establishing new design limits, as regression estimates likely underestimate the change at the ends of the distribution.  相似文献
