The Dash of Faith pilot used a community-based participatory research approach to design an experiential dietary intervention based on two African-American churches, one intervention and one comparison. Congregation members identified components that were incorporated into 12 weekly and 4 monthly sessions, with a goal of increasing fruit and vegetable and lowering fat intake. At 2 months, a marginally significant (p = 0.07) increase in fruit and vegetable consumption was observed in the intervention group but was not maintained at study conclusion. We propose that these mixed findings may be attributable, in part, to bias introduced by the participatory nature of the design.  相似文献

While the expanding body of attribute framing literature provides keen insights into individual judgments and evaluations, a lack of theoretical perspective inhibits scholars from more fully extending research foci beyond a relatively straightforward examination of message content. The current research applies construal level theory to attribute framing research. The authors conduct a meta-analysis of 107 published articles and then conceptually expand this knowledge base by synthesizing attribute framing research and construal level concepts. Results suggest that attribute framing is most effective when there is congruence between the construal level evoked in a frame and the evaluator’s psychological distance from the framed event. A follow-up experiment confirms that the congruence between a frame’s construal level and psychological distance—not simply its valence—appears to be driving attribute framing effects. This research proposes to shift the focus in attribute framing research from that of message composition to a more complex relationship between the message and the recipient.  相似文献

Following metaphorical theories of affect, several research studies have shown that the spatial cues along a vertical dimension are useful in qualifying emotional experience (HAPPINESS is UP, SADNESS is DOWN). Three experiments were conducted to examine the role of vertical motion in affective judgment. They showed that positive stimuli moving UPWARD were evaluated more positively than those moving DOWNWARD, whereas negative stimuli moving DOWNWARD were evaluated as less negative than those moving UPWARD. They showed a valenced congruency effect, but an alternative hypothesis in terms of MORE is UP and LESS is DOWN was also examined. Finally, fluency mechanisms were investigated to confirm that relationships between affect and verticality were in accordance with a valenced congruency effect.  相似文献

Newborn screening (NBS) is a minimally invasive lifesaving test. There is currently no federal mandate for NBS, thus states determine their own screening panel based on the recommendations of the Secretary’s Advisory Committee on Heritable Disorders in Newborn and Children (SACHDNC), which was recently re-chartered as the Discretionary Advisory Committee on Heritable Disorders in Newborns and Children (DACHDNC). After NBS is completed, a couple of residual blood spots remain. While some states allow these spots to be used for public health and scientific research purposes, parents are not always informed about these additional uses. This paper addresses the National Society of Genetic Counselors’ (NSGC’s) position about NBS and blood spot storage/use and the rationale for these positions. The National Society of Genetic Counselors strongly supports newborn screening for the uniform screening panel of conditions recommended by the Secretary’s Advisory Committee on Heritable Disorders in Newborns and Children. NSGC also supports storage and use of blood spot samples by newborn screening laboratories and transparent policies that govern these activities.  相似文献

The aim of this study was to compare the effect on interval discrimination of the presentation of disgusting mutilation images and the presentation of faces expressing disgust. In Experiments 1 and 2, participants had to say whether the second of two images was presented for a shorter or a longer duration than the first (intervals = 400 ms vs. 482 ms). Although the overall probability of responding “long” was not exactly the same in these two experiments, participants reported that duration was longer more often when disgusting mutilation images were presented than when neutral or disgusted faces were presented. In Experiment 3, in which a single-stimulus method was employed, mutilation images were once again reported to be presented for a longer duration than neutral or disgusted faces. The investigation also reveals that discrimination levels are not higher when mutilation images are presented. It is argued that the effect of mutilation images on perceived duration is not due to attention; it is rather attributed to the increased arousal caused by these images.  相似文献

Although often ignored, establishing and maintaining congruence in team members’ temporal perceptions are consequential tasks that deserve research attention. Integrating research on team cognition and temporality, this study operationalized the notion of a temporal team mental model (TMM) at two points in time using two measurement methods. Ninety eight three-person teams participated in a computerized team simulation designed to mimic emergency crisis management situations in a distributed team environment. The results showed that temporal TMMs measured via concept maps and pairwise ratings each positively contributed uniquely to team performance beyond traditionally measured taskwork and teamwork content domains. In addition, temporal TMMs assessed later in teams’ development exerted stronger effects on team performance than those assessed earlier. The results provide support for the continued examination of temporal TMM similarity in future research.  相似文献

The increasing interconnectedness of academic research and external industry has left research vulnerable to conflicts of interest. These conflicts have the potential to undermine the integrity of scientific research as well as to threaten public trust in scientific findings. The present effort sought to identify themes in the perspectives of faculty researchers regarding conflicts of interest. Think-aloud interview responses were qualitatively analyzed in an effort to provide insights with regard to appropriate ways to address the threat of conflicts of interest in research. Themes in participant responses included disclosure of conflicts of interest, self-removal from situations where conflict exists, accommodation of conflict, denial of the existence of conflict, and recognition of complexity of situations involving conflicts of interest. Moral disengagement operations are suggested to explain the appearance of each identified theme. In addition, suggestions for best practices regarding addressing conflicts of interest given these themes in faculty perspectives are provided.  相似文献

Adaptive behavior scales are vital in assessing children and adolescents who experience a range of disabling conditions in school settings. This article presents the results of an evaluation of the design characteristics, norming, scale characteristics, reliability and validity evidence, and bias identification studies supporting 14 norm-referenced, informant-based interviews and rating scales designed to measure adaptive behaviors. To derive these results, the manuals for each of these scales were reviewed using a standardized coding procedure, and information about each scale was double-coded by reviewers. Findings reveal that several evidence-based adaptive behavior scales are available to school psychologists. Concluding recommendations address selection and use of adaptive behavior scales as part of a comprehensive assessment, using the optimal methods of administration of adaptive behavior scales, and interpreting resultant scores that have demonstrated the highest levels of reliability and the largest body of validity evidence.  相似文献

This study examines the role of perceived shared understanding with regard to team performance, taking into account the motivational mechanisms (i.e., group potency and team effort) involved in this relationship and the moderating role of task routineness. Using a multisource approach and a team‐level design, we collected data from 101 teams (i.e., 381 members and their 101 immediate superiors) working in a Canadian public safety organization. The results support the mediating role of group potency and team effort in the relationship between perceived shared understanding and team performance. Moreover, the results show that the relationship between team effort and team performance is moderated by task routineness, such that this relationship is stronger when task routineness is high. On the whole, the findings of this study help to better understand why and under what circumstances perceived shared understanding may enhance team performance.  相似文献
