Cooperative activities among coworkers can provide valuable group-level benefits; however, previous research has often focused on artificial activities that require extraordinary efforts away from the worksite. We investigate organizational benefits that firms might obtain through various supports for coworkers to engage in commensality (i.e., eating together). We conducted field research within firehouses in a large city to explore the role that interacting over food might have for work-group performance. Using a mix of qualitative and quantitative methods, our field research shows a significant positive association between commensality and work-group performance. Our findings establish a basis for research and practice that focuses on ways that firms can enhance team performance by leveraging the mundane and powerful activity of eating.  相似文献

Organizational and applied sciences have long struggled with improving causal inference in quasi‐experiments. We introduce organizational researchers to propensity scoring, a statistical technique that has become popular in other applied sciences as a means for improving internal validity. Propensity scoring statistically models how individuals in a quasi‐experiment have been assigned to conditions in order to estimate treatment effects among individuals with approximately equal probabilities of receiving the treatment. If propensity scores are created from relevant covariates, matching on the propensity score makes treatment assignment ignorable and approximates a true experimental design. We illustrate how matching on the propensity score can be applied by using 2 examples: examining the effects of online instruction and estimating the benefits of preparatory coaching for the SAT. In both cases, propensity‐scoring methods effectively reduced inequivalence between treatment and control groups on many variables. Propensity scoring stands out as a valuable technique capable of improving causal inference from many of organizational research's quasi‐experiments.  相似文献

Alvin Plantinga’s Evolutionary Argument Against Naturalism aims to show that the conjunction of contemporary evolutionary theory (E) with the claim that there is no God (N) cannot be rationally accepted. Where R is the claim that our cognitive faculties are reliable, the argument is:
  1. The probability of R given N and E is low or inscrutable.
  2. Anyone who sees (1) and accepts (N&E) has a defeater for R, and this defeater cannot be defeated or deflected.
  3. Anyone who has an undefeated, undeflected defeater for R has an undefeated, undeflected defeater for everything she believes.
  4. Therefore she has an undefeated, undeflected defeater for (N&E).
Plantinga (2011) defends the second premise. It examines and rejects several candidate defeater defeaters and defeater deflectors. One candidate is Millikan’s teleosemantics. I show that Plantinga’s motives for rejecting teleosemantics as a defeater deflector are inadequate. I then show that teleosemantics is not on its own an adequate defeater deflector. Then I offer an additional premise that constitutes a defeater deflector in conjunction with teleosemantics.  相似文献

This paper considers recent developments in the relations between state, education and religion in Britain in the light of analogous developments in pre-war Japan. The discussion focuses on the emergence of a government-sponsored state cult developed in the late 19th century and retrospectively referred to as ‘state Shinto’. Defined as ‘non-religious’ and disseminated through the school system, it eventually incorporated all other Japanese religions. The analogy with contemporary Britain involves an examination of the background and content of the 1988 Education Reform Act and subsequent (1994) government ‘Guidance’ to schools, particularly in relation to schools religious worship and Religious Education (RE). The analogy with pre-war Japan highlights shifts in the ‘constitutional topography of the sacred’, only partially achieved so far in Britain, whereby religious authority passes from ‘real’ religions to the state, and is then disseminated through the education system as morality.  相似文献

Children with autism spectrum disorders (ASD) experience high rates of anxiety, sensory processing problems, and gastrointestinal (GI) problems; however, the associations among these symptoms in children with ASD have not been previously examined. The current study examined bivariate and multivariate relations among anxiety, sensory over-responsivity, and chronic GI problems in a sample of 2,973 children with ASD enrolled in the Autism Treatment Network (ages 2–17 years, 81.6 % male). Twenty-four percent of the sample experienced at least one type of chronic GI problem (constipation, abdominal pain, bloating, diarrhea, and/or nausea lasting three or more months). Children with each type of GI problem had significantly higher rates of both anxiety and sensory over-responsivity. Sensory over-responsivity and anxiety were highly associated, and each provided unique contributions to the prediction of chronic GI problems in logistic regression analyses. The results indicate that anxiety, sensory over-responsivity and GI problems are possibly interrelated phenomenon for children with ASD, and may have common underlying mechanisms.  相似文献

Whilst survival rates for childhood cancer have improved dramatically over the past three decades, it is still a devastating diagnosis for family members and an illness which severely disrupts the lifestyle of the family unit. Developing an understanding of the impact of the illness on the family is crucial to better support families’ deal with the demands of the illness. In this study nine families in which a child was diagnosed with cancer were interviewed twice over a 12 month period, approximately 6 months apart. Using Interpretative Phenomenological Analysis, a semi-structured interview was used to explicate parent's experience of childhood cancer. The results revealed five super-ordinate themes; (1) a pivotal moment in time, (2) the experience of adaptation in relation to having a sick child, (3) the nature of support, (4) re-evaluation of values during a critical life experience and (5) the experience of optimism and altruism. Findings indicate that parents express both negative and positive experiences as they re-evaluate the meaning and purpose of life, seek to redefine themselves, often in terms of priorities, relationships, sense of community and achieve degrees of optimism and altruism. Implications for addressing the needs of parents and for further research are discussed.  相似文献

ObjectivesThere is growing evidence that mindfulness has positive consequences for both psychological and physical health in both clinical and non-clinical populations. The potential benefits of mindfulness underpin a range of therapeutic intervention approaches designed to increase mindfulness in both clinical and community contexts. Self-guided mindfulness-based interventions may be a way to increase access to the benefits of mindfulness. This study explored whether a brief, online, mindfulness-based intervention can increase mindfulness and reduce perceived stress and anxiety/depression symptoms within a student population.MethodOne hundred and four students were randomly allocated to either immediately start a two-week, self-guided, online, mindfulness-based intervention or a wait-list control. Measures of mindfulness, perceived stress and anxiety/depression were administered before and after the intervention period.ResultsIntention to treat analysis identified significant group by time interactions for mindfulness skills, perceived stress and anxiety/depression symptoms. Participation in the intervention was associated with significant improvements in all measured domains, where no significant changes on these measures were found for the control group.ConclusionsThis provides evidence in support of the feasibility and effectiveness of shorter self-guided mindfulness-based interventions. The limitations and implications of this study for clinical practice are discussed.  相似文献

The use of attention training protocols for the treatment of generalized social anxiety disorder (SAD) is undergoing increased examination. Initial investigations were positive but more recent investigations have been less supportive of the treatment paradigm. One significant limitation of current investigations is overreliance on self-report. In this investigation, we expanded on initial investigations by using a multimodal assessment of patient functioning (i.e., including behavioral assessment). Patients with a primary diagnosis of SAD (n = 31) were randomly assigned to eight sessions of attention training (n = 15) or placebo/control (n = 16). Participants were assessed at pre- and posttreatment via self- and clinician-report of social anxiety as well as anxious and behavioral response to two in vivo social interactions. Results revealed no differences between groups at posttreatment for all study outcome variables, suggesting a lack of effect for the attention training condition. The results are concordant with recent investigations finding a lack of support for the use of attention training as an efficacious treatment for patients with SAD.  相似文献
