The objective of this research is to investigate the possible difference in accumulation of adversity over the life course among decedent gamblers and living control gamblers in the province of Quebec, Canada. A sample of 90 adult men, 41 living participants and 49 suicide decedents, met the criteria for at-risk and problem gambling over the last five years. Data were obtained from informants in the case of suicide and directly from living controls during semi-structured face-to-face interviews using SCID I and II, SOGS, Module K and a recount of life trajectories methodology. The results showed a high level of adversity throughout the life trajectories of both groups. However, the living gamblers faced more difficulties during their lifespan than the suicide victims. In the last six months before their death, suicide victims had a significantly higher number of mental health disorders, especially co-morbid mental health disorders and anxiety, compared to the living controls. We also observed a rapid escalation of difficulties, more life events and more psychological distress in the last six months of their lives among the suicide decedents. Suicidal behaviour needs to be carefully investigated by medical staff and mental health practitioners, especially when gamblers demonstrate evidence of mental health disorders or financial difficulties. 相似文献

Previous research suggests that parents may be less happy than non-parents. We critically assess the literature and examine parents’ and non-parents’ happiness-trends using the General Social Survey (N = 42,298) and DDB Lifestyle Survey (N = 75,237). We find that parents are becoming happier over time relative to non-parents, that non-parents’ happiness is declining absolutely, and that estimates of the parental happiness gap are sensitive to the time-period analyzed. These results are consistent across two datasets, most subgroups, and various specifications. Finally, we present evidence that suggests children appear to protect parents against social and economic forces that may be reducing happiness among non-parents. 相似文献

The current study examines how the horror-based AMC television series The Walking Dead portrays religion in terms of a reframing of the role, if any, of faith in a higher power, and the portrayal of the faithful. The religious-themed discourse of this highly successful story about survivors of a zombie apocalypse as presented through dialogic and visual imagery serves as the text analyzed here; specifically, related episodes set in churches at two separate points in the series that combine to offer a metaphor of “structure” used to disassemble and reconstruct the role of religion. These episodes interlace religious themes to develop an overarching message that forms a representative anecdote of replacement in which the notion of “faith” becomes redefined. 相似文献

This study examined whether prenatal reflective functioning (RF) was related to mothers’ interactive style across contexts with their 6‐month‐old infants (M age = 6.02 months, SD = 0.41, 54% boys), and to what extent quality of prenatal RF could account for the influence of accumulated risk on maternal interactive behavior. Accumulated risk was defined as the sum‐score of a selection of risk factors that have been associated with suboptimal infant development. Mother–infant dyads (N = 133) were observed during free play, two teaching tasks, and the Still‐Face Paradigm (SFP). Better prenatal RF was associated with more positive maternal behavior in all settings and less negative behavior during teaching and SFP reengagement. Accumulated risk and prenatal RF predicted shared variance in maternal interactive behavior (with unique predictive effects observed only for RF on sensitivity during teaching and SFP play, and for accumulated risk on sensitivity and positive engagement during SFP play, and internalizing‐helplessness during SFP reengagement). Accumulated risk had an indirect effect on maternal sensitivity during teaching and SFP play through prenatal RF. These findings suggest not only that RF may be targeted prenatally to improve mother–infant interactions, but also that enhancing RF skills may ameliorate some of the negative consequences from more stable perinatal risk factors that influence parent–child interactions. 相似文献

Interaction with employees is essential for organizational leaders. If executives do not communicate well, important processes like giving feedback, setting goals or guiding change processes can nevertheless lead to resistance from subordinates when communication is received as more threatening than challenging. Conveying messages in ways that provoke challenge instead of threat appraisals can be achieved via employee-oriented communication, but this may require taking peoples’ differing motivational orientations into account. This is because motivational orientations partially determine what kind of information is motivating to us, which goals and strategies we prefer, and how we deal with changes. In this regard, Regulatory Focus Theory (Higgins 1997) compares the gain- and success-sensitive promoter with the loss- and failure-sensitive preventer. This article applies this theory to the organizational psychological context and outlines practical implications for managers. The goal of the piece is to provide managers a leadership tool that acknowledges the diversity of peoples’ motivational styles and by that revealing a need-oriented and more efficient way in communication with subordinates. 相似文献

In this article, we define the concept of “risk work,” which aims to make visible working practices to assess or manage risk, in order to subject these practices to sociological critique. This article reviews and synthesizes existing published literature to identify components of risk work: (a) translating risk into different contexts, (b) minimizing risks in practice, and (c) caring in the context of risk. We argue that these three components of risk work raise important tensions for workers that have been inadequately explored in the literature to date. We propose that future research should additionally focus on practitioner subjectivity and identity in risk work. In addition, we argue that comparative research—across type of risk and different contexts—and methodological and theoretical diversity would enhance this emerging field of research. 相似文献

Analytic and conceptual ambiguity associated with the study of legitimacy have motivated debates over the utility of this construct in the analysis of violent political conflict. Using these debates as a point of departure, I review several challenges that have limited the study of legitimacy in this area and discuss two features of legitimation that have gone widely overlooked: (i) the asymmetric causes and effects of legitimacy and illegitimacy, and (ii) the relational dynamics of legitimation. I argue that turning explicit analytic attention to the asymmetry and relationality of legitimacy and illegitimacy allows us to overcome the most intractable challenges associated with the analysis of legitimation in violent conflict. 相似文献

This paper examines forecast error with an intention not to minimize forecast error so much as to bias the resultant error in order to achieve better managerial results. Much work has been accomplished by other researchers toward the goal of minimizing forecast error—sometimes by the use of sophisticated forecasting techniques. The results of this paper indicate that manipulating forecast error bias may be the better managerial strategy as opposed to going to great lengths to minimize forecast error. Subject Areas: Forecasting, Aggregate Planning, Capacity Planning, and Production/Operations Management. 相似文献

This study used a factorial experimental design and a new modeling methodology to investigate the impact of a number of labor scheduling flexibility alternatives and labor requirements characteristics on labor utilization within a tour scheduling environment. Break-placement flexibility and shift-length flexibility were found to be extremely effective in improving labor utilization for all labor requirement distributions used. Flexibility with respect to the number of days included in a tour schedule resulted in substantial improvement in labor utilization for all labor requirements distributions exhibiting daily and/or weekly variation. Surprisingly, virtually no improvement in labor utilization was achieved for any labor requirement distribution by the removal of requirements for consecutive days off. In addition, almost no improvement was found by allowing the shift start time to vary across the working days included in tours. High labor requirement amplitude was found to have a strong adverse effect on labor utilization while longer operational days were associated with improved labor utilization for all labor requirement distributions. We discuss the implications of these results for service operations management and provide suggestions for future research. 相似文献
