The fourth wave of the National Congregations Study (NCS-IV) was conducted in 2018–2019 with a nationally representative sample of congregations from across the religious spectrum. The NCS-IV included a fresh cross-section of congregations generated in conjunction with the 2018 General Social Survey and a panel of congregations that participated in the third NCS wave. Data were collected via a 65-minute interview with one key informant from 1,262 congregations. The cooperation rate was 74 percent; the conservatively calculated response rate was 69 percent. Information was gathered about multiple aspects of congregations’ social composition, structure, activities, leadership, and programming. Approximately two-thirds of the NCS-IV questionnaire replicates items from previous NCS waves. This introduction to the NCS-IV symposium describes NCS-IV methodology and special features of the new data. The three symposium articles present NCS-IV results about congregations’ political activities, racial and ethnic composition, and worship practices. 相似文献

Organizational settings are replete with changing stimulus contexts and contingencies, which makes relapse a particularly relevant framework for understanding the ways in which controlling stimuli influence employee responding. The purpose of the current study was to develop a translational model to assess renewal of desirable behavior in a simulated workplace with neurotypical adults. Experiment 1 assessed renewal of desirable behavior using a computerized check processing task. Experiment 2 extended the findings and the translational utility of the experimental arrangement to implementation of a behavior-analytic teaching procedure. Results across both experiments demonstrated renewal of desirable behavior. Overall, the current methodology and findings extend the human operant literature on renewal and demonstrate a translational model that brings together operant renewal and organizational behavior management. 相似文献

In the hope of complementing the structural perspective in upper echelon research and advancing a fine-grained understanding of dyadic leadership influence in management teams, the current study combines two types of intrateam structures—leadership network and friendship network—to create a multidimensional conceptualization of leadership structure in management teams. Specifically, we propose that management teams with a denser singular leadership network (i.e., a network consisting of many leadership ties that are not coupled with friendship ties) should have lower management team cohesion, which subsequently renders worse business unit performance. To contrast, management teams with a denser multiplex network (i.e., a network consisting of many leadership ties that are coupled with friendship ties) should have higher management team cohesion, which subsequently renders better business unit performance. Guided by structural contingency perspective, we further propose that management team task interdependence will strengthen team cohesion's positive impact on business unit performance. To test the hypothesized model, we collected team-level social network data and multiple-wave survey data from 697 managers nested in 148 hotels (i.e., 148 management teams) owned by a large hospitality company. We also obtained objective performance data for each hotel (i.e., occupancy percentage rate and revenue per available room per day) as the criterion measure. The data supported our hypotheses. The theoretical and practical implications of our findings are discussed. 相似文献

This study explored counselors’ conceptualization and use of encouragement as a therapeutic tool. Responses to two questions from 100 South Korean youth counselors were analyzed using consensual qualitative research–modified. As a result, six categories emerged under each domain. Implications for counseling and future studies are discussed. Este estudio exploró la conceptualización y el uso del apoyo como herramienta terapéutica por parte los consejeros. Usando el método modificado de investigación cualitativa consensual, se analizaron las respuestas proporcionadas a dos preguntas por 100 consejeros surcoreanos que trabajan con jóvenes. Como resultado, surgieron seis categorías bajo cada dominio. Se discuten las implicaciones para la consejería e investigaciones futuras. 相似文献

The Air Force SPACECAST 2020 study identified and prioritized some future space systems and technologies required in the next century. This paper presents the results of research on the SPACECAST 2020 value model. The model determines and prioritizes future space systems’ utility towards controlling and exploiting space. This research identifies the assumptions and simplifications in the additive utility function and assesses modifications. The research shows that mutual utility independence of the mission areas is a reasonable assumption. Mutual utility independence allows the use of the multiplicative and multilinear utility functions. Also, the SPACECAST 2020 scoring functions used the same scoring scale and only measured the utility of future capabilities. This study makes modifications to the SPACECAST 2020 measure-of-merit scoring functions. It replaces most of these functions with either a concave, convex, linear or ‘S’ scoring function, which have expanded capability ranges to include both current and future capabilities. The modified scoring functions and alternative utility functions do not alter the SPACECAST 2020 results but do improve the credibility and future usefulness of the model. This study shows that the initial assumption of using an additive utility function is also valid. © 1997 John Wiley & Sons, Ltd. 相似文献

Desirability bias is the tendency to overpredict desirable outcomes and underpredict unwanted outcomes. Previous research suggests that this bias is quite pervasive among non-experts but there is very scant evidence of its intensity among experts. For at least twenty years, financial academics and, to a lesser extent, practicing investment managers have claimed that the financial markets are among the most efficient and bias free in existence. Therefore, this paper examines the degree of desirability bias among expert and practicing US and Taiwanese investment managers. The empirical results suggest that desirability bias does appear to be a characteristic of these experts. © 1997 John Wiley & Sons, Ltd. 相似文献

Reservoir management is inherently multicriterial, since any release decision involves implicit trade-offs between various conflicting objectives. The release decision reflects concerns such as flood protection, generation of hydroelectric power, dilution of wastewater and heated effluent, supply of municipal, agricultural and industrial water, maintenance of environmental standards and satisfaction of recreational needs. This paper presents a framework for analysing trade-offs between several decision criteria and includes the dilution of heated effluents from downstream thermoelectric power generation in an optimization model for reservoir management. The model is formulated and analysed in an interactive multicriteria decision-making (MCDM) modelling framework. Rather than providing specific target levels or ad hoc constants in a goal-programming framework as proposed elsewhere, this multicriteria framework suggests a systematic way of evaluating trade-offs by progressive preference assessment. The MCDM model, based on a Chebyshev metric and a contracted cone approach, is learning-oriented and permits a natural exploration of the decision space while maintaining non-dominated decisions. A detailed case study of the Shellmouth Reservoir in Manitoba, Canada serves as an illustration of the model. © 1998 John Wiley & Sons, Ltd. 相似文献
