In this article we use a sample of 40 years of sociology journal articles (N = 1,024) on religion to ask what role funding plays in some of the leading trends in the subdiscipline. Our analysis reveals a considerable increase in the number of published articles on religion with funding over the past 40 years as well as a shift away from public funding as the primary source of funding. Engaging our findings in previous analyses of this database, we surprisingly find a positive correlation between public funding and positive socio‐evaluative findings in articles on religion, but not between private funding and positive socio‐evaluative findings. We also find a positive correlation between funding from religious organizations and research on religion in the United States and a weak, but negative, correlation between funding from religious organizations and research on non‐Christian religious traditions. We do not find a relationship between funding and causal order.  相似文献

This study examined the mediating roles of career decision‐making self‐efficacy (a domain‐specific motivational variable) and occupational engagement (a behavioral variable) on the relationship between internal locus of control (a general motivational variable) and career adaptability among college students in South Korea (N = 310). The findings extend past research on career adaptability by identifying a relationship among the variables.  相似文献

Adolescence is a developmental period with high vulnerability to sleep problems. However, research identifying distinct patterns and underlying determinants of sleep problems is scarce. This study investigated discrete subgroups of, changes in, and stability of sleep problems. We also examined whether peer victimization influenced sleep problem subgroups and transitions in patterns of sleep problems from late adolescence to young adulthood. Sex differences in the effects of peer victimization were also explored. In total, 1,455 male and 1,399 female adolescents from northern Taiwan participated in this longitudinal study. Latent transition analysis was used to examine changes in patterns of sleep problems and the effects of peer victimization on these changes. We identified three subgroups of sleep problems in males and two in females, and found that there was a certain level of instability in patterns of sleep problems during the study period. For both sexes, those with greater increases in peer victimization over time were more likely to change from being a good sleeper to a poor sleeper. The effects of peer victimization on baseline status of sleep problems, however, was only significant for males, with those exposed to higher levels of peer victimization more likely to be poor sleepers at baseline. Our findings reveal an important role of peer victimization in predicting transitions in patterns of sleep problems. Intervention programs aimed at decreasing peer victimization may help reduce the development and escalation of sleep problems among adolescents, especially in males.

The effects of the response–reinforcer dependency on resistance to change were studied in three experiments with rats. In Experiment 1, lever pressing produced reinforcers at similar rates after variable interreinforcer intervals in each component of a two‐component multiple schedule. Across conditions, in the fixed component, all reinforcers were response‐dependent; in the alternative component, the percentage of response‐dependent reinforcers was 100, 50 (i.e., 50% response‐dependent and 50% response‐independent) or 10% (i.e., 10% response‐dependent and 90% response‐independent). Resistance to extinction was greater in the alternative than in the fixed component when the dependency in the former was 10%, but was similar between components when this dependency was 100 or 50%. In Experiment 2, a three‐component multiple schedule was used. The dependency was 100% in one component and 10% in the other two. The 10% components differed on how reinforcers were programmed. In one component, as in Experiment 1, a reinforcer had to be collected before the scheduling of other response‐dependent or independent reinforcers. In the other component, response‐dependent and ‐independent reinforcers were programmed by superimposing a variable‐time schedule on an independent variable‐interval schedule. Regardless of the procedure used to program the dependency, resistance to extinction was greater in the 10% components than in the 100% component. These results were replicated in Experiment 3 in which, instead of extinction, VT schedules replaced the baseline schedules in each multiple‐schedule component during the test. We argue that the relative change in dependency from Baseline to Test, which is greater when baseline dependencies are high rather than low, could account for the differential resistance to change in the present experiments. The inconsistencies in results across the present and previous experiments suggest that the effects of dependency on resistance to change are not well understood. Additional systematic analyses are important to further understand the effects of the response–reinforcer relation on resistance to change and to the development of a more comprehensive theory of behavioral persistence.  相似文献

Drawing upon functional theories of attitudes and the organizational justice literature, the current research suggests that people's attitudes toward justice likely serve an instrumental function (grounded in self‐interest, rewards maximization, and punishment minimization) as well as a value‐expressive function (grounded in the expression of self‐concept and values). Importantly, these two functions co‐exist and interact to influence supervisors’ justice behavior and the consistency of such behavior via supervisors’ justification for unjust behavior. Findings from a set of experimental and correlational studies confirmed these predictions. The positive effects of supervisors’ value‐expressive function on justice behavior and its consistency were stronger when their instrumental function was lower (vs. higher), and justification for unjust behavior mediated these effects. Also, supplementary analyses showed that the consistency of supervisors’ justice behavior positively predicted subordinates’ overall justice perceptions beyond the effects of the overall level of justice behavior. We conclude by discussing the theoretical and practical implications of these findings.  相似文献

This study examines the individual and contextual factors associated with sociopolitical control expressed by immigrants in southern Spain. We used hierarchical linear modeling to evaluate the relations between individual (community participation, social connectedness, and perceived cultural competence of receiving community services) and municipality characteristics (city community participation, city social connectedness, and city community services’ cultural competence) and immigrants’ feelings of sociopolitical control. Data were analyzed using a two‐level model based on 707 Moroccan immigrants in 25 municipalities. After adjusting for gender, educational level, and psychosocial confounding factors, we observed a positive association between social connectedness and sociopolitical control at the individual level. At the contextual level, we observed a positive association between (a) city community participation, (b) city social connectedness, and (c) city community services’ cultural competence, and sociopolitical control. Indeed, living in a municipality where there are community services with high levels of cultural competence and where, on average, many people participate in organizations and neighbors are connected, was associated with higher levels of perceived control in the sociopolitical domain for immigrants. We also discuss implications for community‐based research and practice.  相似文献

Research to date has underlined the importance of positive organizational psychology to improve health and psychological well‐being (PWB) in the workplace. The purpose of the present research is to test a model linking satisfaction of the basic psychological needs for autonomy, competence, and relatedness, as identified by self‐determination theory (SDT), and various individual work‐related outcomes, such as job satisfaction, PWB, and health problems in Spanish employees. Nationally representative data from the sixth European Survey on Working Conditions is Spain were used. Structural equation modeling was performed to examine the mediational role of job satisfaction in the relationships between psychological need satisfaction in the workplace and its consequences for PWB and health problems in Spanish employees. The results indicated that the fulfillment of basic psychological needs in the workplace is related to higher job satisfaction and that higher job satisfaction is associated with higher PWB and fewer health problems. Higher perceived competence and relatedness in the workplace were also related to greater PWB and fewer health problems. These results suggest that SDT is a valid approach that may guide interventions in the workplace to promote job satisfaction, PWB, and physical health in employees.  相似文献

The present research focused on two primary goals: (a) identifying the content of sentiments about the Roma to which Hungarians are exposed during everyday family conversations, and (b) determining which types of everyday sentiments about the Roma most strongly predict Hungarian respondents’ anti‐Roma prejudice. Content analyzing open‐ended responses from a representative sample of Hungarians (N = 505), we found that more than 76% of the respondents reported being exposed to negative stereotypes about the Roma, 27% to threats posed by Roma, and 16% to overt dehumanization of Roma; additionally more than 20% reported hearing no positive sentiments about the Roma in everyday family conversations. We then examined which negative and positive sentiments most strongly predicted respondents’ anti‐Roma prejudice (using measures of social distance and modern racism). Higher social distance scores were predicted by a lack of positive sentiments, whereas lower social distance scores were most strongly predicted by unambiguously positive sentiments expressed during family conversations. Higher modern racism scores were further predicted by sentiments expressing dehumanization, threat, and violence against Roma. Together, these results attest to the extremity of anti‐Roma sentiments expressed regularly by Hungarians, and suggest how exposure to specific sentiments may foster anti‐Roma hostility. Moreover, these findings provide guidance regarding the specific negative anti‐Roma sentiments that should be combated to enhance the effectiveness of anti‐prejudice interventions.  相似文献

Research on tact acquisition by children with autism spectrum disorder (ASD) has often focused on teaching participants to tact visual stimuli. It is important to evaluate procedures for teaching tacts of nonvisual stimuli (e.g., olfactory, tactile). The purpose of the current study was to extend the literature on secondary target instruction and tact training by evaluating the effects of a discrete‐trial instruction procedure involving (a) echoic prompts, a constant prompt delay, and error correction for primary targets; (b) inclusion of secondary target stimuli in the consequent portion of learning trials; and (c) multiple exemplar training on the acquisition of item tacts of olfactory stimuli, emergence of category tacts of olfactory stimuli, generalization of category tacts, and emergence of category matching, with three children diagnosed with ASD. Results showed that all participants learned the item and category tacts following teaching, participants demonstrated generalization across category tacts, and category matching emerged for all participants.  相似文献
