Objectives: Anxiety sensitivity (AS) is associated with cannabis use. People high in AS may use cannabis to cope with elevated anxiety. This association is consistently supported in the literature. However, we have much to learn about the mechanisms of the AS pathway to cannabis use. We aimed to examine negative urgency—the tendency to act impulsively when distressed—as a mediator of the association of AS with cannabis problems and cannabis dependence symptoms. We hypothesized that negative urgency would uniquely mediate the association of AS with cannabis outcomes after controlling for other facets of impulsivity. Participants and Methods: Postsecondary students (= 91; Fall 2012) completed online self-reports. To participate, students needed to be ≥18 years old, enrolled in postsecondary studies, and needed to report current cannabis use. Results: Negative urgency uniquely mediated associations between AS and cannabis problems and dependence symptoms. Conclusions: Our findings suggest a mechanistic role of negative urgency in the AS pathway to cannabis misuse.  相似文献

Considerable evidence has suggested that problem gambling may be transitory and episodic, with gamblers routinely moving in and out of clinical thresholds. Findings in qualitative and quantitative studies have converged on identifying preliminary evidence for the role of life events as motivators and contributing factors for gambling changes over time. The aim of this study was to conduct an exploratory analysis of the relationship between life events, their respective experience as positive or negative, and gambling trajectories among problem gamblers intending to quit. Life event occurrence and ratings as positive or negative, and changes in gambling severity were analyzed over a 12-month period for 204 adult problem gamblers intending to reduce or quit their gambling. Overall, mixed effects models revealed several relationships between life events and both the magnitude and direction of gambling change over time. In particular, gamblers who experienced a greater number of positive events or specific events such as legal events, the adoption/loss of a child, or negative changes to their social relationships, finances, work environments or social/health activities were more likely to exhibit greater gambling reductions over time. Conversely, gamblers who experienced a greater number of negative events, such as family bereavement, the dissolution of a marriage, or negative changes to their residence exhibited smaller gambling reductions or increases in gambling severity. Possible mechanisms which may explain the findings and the importance of examining the subjective experience of life events are discussed. Recommendations for future studies examining associations between life events and gambling trajectories are provided.  相似文献

ABSTRACT

In this article, we show how a common type of material environment in office organizations, namely offices with doors left open, enables and sustains the initiation of unscheduled, informal encounters. Using video recordings of naturally occurring interactions, we identify and describe a recurrent practice whereby visitors, mainly through their embodied conduct as they approach the doorway, are recognized by their recipients as initiating an encounter. We unpack the systematic practices and resources involved and analyze a series of variations through which co-workers deal with three interactional problems: obtaining the office occupant’s attention, negotiating availability, and negotiating entitlement. The article (1) demarcates a set of practices typical of unscheduled encounters in office organizations; (2) sheds new lights on how shared and fractured visual spaces can be used as resources to produce complex organizational meanings; and (3) proposes an approach of organizational activity and knowledge as inherently interactional, embodied and material.  相似文献

This article in the journal Gruppe. Interaktion. Organisation (GIO) presents mindfulness as a starting point for coping with the increasing and changing demands of today’s workplaces. Based on a differentiated analysis of mindfulness on the individual and organizational level, we discuss their separate contribution to resilient behavior in the workplace as well as on psychological well-being and work engagement. These assumptions were empirically verified. Overall, 172 persons participated in the study, which was implemented as a web-based questionnaire. The results showed that individual and organizational mindfulness independently contributed to resilient behavior in the workplace. Furthermore, individual mindfulness and resilient behavior promoted psychological well-being. Both individual and organizational mindfulness were significantly associated with work engagement. Additional analyses revealed that these effects were mediated by resilient behavior. In summary, the results demonstrated that individual and organizational mindfulness are distinct constructs whose influence on psychological well-being and work engagement could be partly explained by resilient behavior in the workplace.  相似文献

Reducing the prevalence of household food insecurity has been a long-standing objective of the federal government. Previous research has found many negative consequences of food insecurity for families and households but has not examined its relationship with housing instability. Using longitudinal data from the Fragile Families and Child Wellbeing Study, difference-in-difference models show that food insecurity is associated with housing instability. The association remains statistically significant after accounting for potential selection and unobserved heterogeneity using propensity score matching and excluding households that experienced prior housing instability from the sample. Examining potential mediating factors, I find that material hardship explains about half of this association. These findings suggest that maintaining a strong social safety net would reduce the risk that families experience material hardship and housing instability, which may also reduce the risk of homelessness.  相似文献

The conventional view of the value‐creation chain suggests offering high‐value propositions at the product level (in terms of benefits provided by elements of the product) to attain high‐value perceptions at the customer level, which should ultimately result in high‐value appropriation at the firm level (i.e. relationship, volume, pricing and financial success). This study challenges this view and provides a differentiated understanding of the value‐creation chain. With a multi‐industry sample of 339 companies and a sample of 626 customers to validate managerial assessments, the authors apply a configurational approach to identify whether and to what extent offering high‐value propositions at the product level is necessary or sufficient for achieving superior value perceptions at the customer level and high‐value appropriation at the firm level. Taking into account the company‐internal and company‐external environment of the value‐creation chain, the study identifies seven value‐creation chain constellations.  相似文献

There is great variation in views on and treatment of minorities such as gay men across the world. We are the first to pinpoint what features of societies are beneficial to gay men’s quality of life by using a unique new cross-country dataset covering 110 countries, the Gay Happiness Index. It covers how gays perceive public opinion about them, how they experience behavior towards them and how satisfied they are with their lives. Our study is based on the premise that it is important to look at minority-specific effects of policies and institutions and not solely at the effects for the average citizen, as well as the transmission mechanisms through which policies and institutions affect life satisfaction. We find that factors such as equal legal rights for gay people, GDP per capita, democracy and globalization relate positively to the quality of life of gay men, primarily by shaping public opinion and behavior in a pro-gay direction. Religion (the shares of Muslims and Orthodox Christians) and living in a post-communist country tend to relate negatively to our quality of life indicators. Most of these factors have been shown to matter for the well-being of people in general as well, which may be taken to suggest that gay people benefit from being included in society—legally, socially and economically—on the same terms as others.  相似文献
