Objective. This study tests the claim that areas with higher levels of social capital have superior economic performance. Method. The 14‐measure index of social capital created by Robert Putnam is reconstructed for an extended time period and integrated into cross‐sectional regression models including physical capital, human capital, and other factors relevant to state economic performance. Results. The analysis shows that social capital has no discernable influence on aggregate measures of output and employment. However, it does have a positive and significant impact on measures of economic equality and employment stability. Conclusions. This study does not support the claim that social capital is a general prerequisite for prosperity, but it does suggest that it may serve to reinforce a particular mode of communitarian economic development.  相似文献

Much of what is known about emotions and sexuality explores the relationship enhancing qualities of positive affect. This research extends the current literature by focusing on the association between negative feelings and sexual thoughts and experiences in the context of close relationships, controlling for the effect of positive feelings. Specifically, the unique effects of daily negative feelings toward one's partner in general and specific negative feelings (i.e., anger, anxiety, and sadness) on the sexual experience of heterosexual, gay male, and lesbian relationships were explored. Participants completed an initial questionnaire followed by daily diary measures for 14 consecutive days. Positive feelings were positively associated with sexual variables as expected. Negative feelings were associated with increases in sexual behaviors for heterosexual men and women and gay men, but not lesbian women. Sadness showed a unique positive association with arousal, lust, wanted sexual behavior, and sexual behavior for heterosexual men and women and gay men, but not lesbian women. Neither anger nor anxiety was uniquely associated with the sexual experience for heterosexual or same-sex couples.  相似文献

Researchers have found linear associations among maternal and child characteristics. However, family systems theorists suggest that relationships are more complex and family members are interdependent. We used actor–partner interdependence modeling to unravel associations among maternal and child characteristics to predict outcomes in adolescence. We used data from 361 mother–child dyads from the Longitudinal Studies of Child Abuse and Neglect and found both actor and partner effects. Maternal depression and history of victimization were associated with children's later reports of lower mother–adolescent relationship quality. Children's perceptions of relationship quality were also associated with mothers' later depressive symptoms and perceptions of relationship quality. Overall, results highlighted interdependence among mothers and their children over time. We discuss implications for marriage and family therapists.  相似文献

Much attention has been devoted to the relationship between Hispanic immigration and violent offending at the macro‐level, including how it varies across racial and ethnic groups. Unfortunately, little attention has been paid to the conditioning effect of the race/ethnicity of the victim, or how Hispanic immigration is associated with crime by one racial/ethnic group against members of the same or different groups. Using National Incident‐Based Reporting System offending estimates and American Community Survey data, we examine the association between Hispanic immigration and black intra‐ and intergroup (black‐on‐white and black‐on‐Hispanic) homicide, robbery, and serious index violence in over 350 U.S. communities. We employ advanced imputation methods to address missing data that have constrained much prior research, as well as utilize crime measures adjusted for the likelihood of random contact between groups. Findings suggest that (1) Hispanic immigration has a positive association with black violence on the whole, but that (2) this association is conditioned by the race/ethnicity of the victim. Our results reinforce the importance of distinguishing across offender–victim dyads in research on the immigration–crime nexus, particularly in light of competing theoretical expectations. Directions for future research and policy are discussed.  相似文献

Understanding the trends and predictors of attrition rate, or the proportion of collected data that is excluded from the final analyses, is important for accurate research planning, assessing data integrity, and ensuring generalizability. In this pre-registered meta-analysis, we reviewed 182 publications in infant (0–24 months) functional near-infrared spectroscopy (fNIRS) research published from 1998 to April 9, 2020, and investigated the trends and predictors of attrition. The average attrition rate was 34.23% among 272 experiments across all 182 publications. Among a subset of 136 experiments that reported the specific reasons for subject exclusion, 21.50% of the attrition was infant-driven, while 14.21% was signal-driven. Subject characteristics (e.g., age) and study design (e.g., fNIRS cap configuration, block/trial design, and stimulus type) predicted the total and subject-driven attrition rates, suggesting that modifying the recruitment pool or the study design can meaningfully reduce the attrition rate in infant fNIRS research. Based on the findings, we established guidelines for reporting the attrition rate for scientific transparency and made recommendations to minimize the attrition rates. This research can facilitate developmental cognitive neuroscientists in their quest toward increasingly rigorous and representative research.  相似文献

Theories across cognitive domains propose that anticipating upcoming sensory input supports information processing. In line with this view, prior findings indicate that adults and children anticipate upcoming words during real-time language processing, via such processes as prediction and priming. However, it is unclear if anticipatory processes are strictly an outcome of prior language development or are more entwined with language learning and development. We operationalized this theoretical question as whether developmental emergence of comprehension of lexical items occurs before or concurrently with the anticipation of these lexical items. To this end, we tested infants of ages 12, 15, 18, and 24 months (N = 67) on their abilities to comprehend and anticipate familiar nouns. In an eye-tracking task, infants viewed pairs of images and heard sentences with either informative words (e.g., eat) that allowed them to anticipate an upcoming noun (e.g., cookie), or uninformative words (e.g., see). Findings indicated that infants' comprehension and anticipation abilities are closely linked over developmental time and within individuals. Importantly, we do not find evidence for lexical comprehension in the absence of lexical anticipation. Thus, anticipatory processes are present early in infants' second year, suggesting they are a part of language development rather than solely an outcome of it.  相似文献

Objective

In the current study, we seek to shed new light on the role of religion in American gun culture by considering whether images people hold of God affect the probability of gun ownership and the experience of empowerment through guns for religious Americans (i.e., the extent to which owners derive security, identity, and status from their guns).

Methods

We analyze nationally representative data from the 2021 Baylor Religion Survey in the United States. Binary logistic and ordinary least squares regression models were used.

Results

We failed to observe any associations between God images and gun ownership. However, among gun owners (n = 430), belief in an engaged God was associated with lower levels of gun empowerment, while belief in a judgmental God was associated with higher levels.

Conclusion

God images may contribute to the experience of empowerment through guns by representing spiritual connection and intimacy or divine anger and retribution. We suggest that future research delve deeper into the intersection of God images and gun-related beliefs and behaviors.  相似文献

信息哲学中存在的许多争议,大都是因为“信息”一词在不同使用语境中指称的现象不同导致的。香农将“信息”概念的形式缩减为通信媒介的统计属性,这使得它在以解释功能和指称为特色的领域中丧失了有用性。建议可以从区分媒介或信号属性、指称属性以及规范或功能属性的角度,更准确地描述信息概念。由此,基于符号媒介的内在统计特性所提供的功能可供性,信息理论可以对符号载体和指称对象的必要过程结构进行描述。  相似文献
