New forms of youth social and political participation have been termed ‘Slacktivism’ – low-cost online forms of social engagement that decrease subsequent offline participation. Previous experimental work has provided support for a ‘Slacktivism effect,’ but it is unclear if this theoretical model applies to youth media sharing on social networking sites. This study uses a novel sharing simulation paradigm to test the effect of publicly vs. anonymously sharing a social cause video on subsequent willingness to engage in offline helping behavior. Results show that publicly (as compared to anonymously) sharing a selected video on one’s own Facebook wall led to a greater willingness to volunteer for an issue-related cause. Participants’ existing use of social media for engagement in social issues/causes moderated the effect, such that only participants low in use of social media for social engagement were susceptible to the sharing manipulation. Implications for reconceptualizing media sharing as a unique form of online participation beyond ‘Slacktivism’ are discussed.  相似文献

This paper examines the relationship between the entry of the baby boom into the workforce and the productivity slowdown. Lucas (Bell J Econ 9(2):508–523, 1978) shows how management quality plays a role in determining output. The baby boom’s entry into the workforce resulted in more managers from smaller, pre-baby boom cohorts. These marginal managers were necessarily of lower quality, leading to a drop in total factor productivity. As the boomers aged, this effect was reversed. A calibrated model of managers, workers, and firms suggests that the management effects of the baby boom may explain roughly 20% of the observed productivity slowdown and resurgence.  相似文献

Parents’ perceptions of their neighbourhoods are important for child health outcomes. This study compared views among mothers in inner versus outer suburbs of Melbourne, Australia using a mixed methods approach. Mothers of preschool-aged children were recruited via playgroups, mother’s groups and preschools and interviewed face-to-face regarding their local area as a good place to raise a family, with a second open-ended interview focussing on mothers’ ideals and experiences of raising children in their current location. Findings demonstrated that mothers had different ideals for, and experiences of, raising their children in their neighbourhoods. Inner suburban mothers valued a manageable work/family balance and access to public transport over the size of their homes. However, access to childcare, secondary schooling and heavy traffic were issues, with the latter two being reasons for moving from the municipality. In contrast, outer suburban mothers preferred a larger home in neighbourhoods that they perceived as low crime, over accessibility to work. Access to a car and activities for their children were also important. Findings suggest no ‘one size fits all’ in respect to what features mothers expect from a good place to raise a family, or how they experience these features. This has implications for service delivery and social planning of suburbs.  相似文献

By using economics, welfare and social network factors as frames of reference, this study aims to explore the relationship between these three factors and net migration to various US states. Adopting related variables collected from official aggregate data, this study first utilizes Logit Regression analysis to draw out seven variables that best explain net migration to the various states, then employs these variables in LISREL analyses to build a model explaining the factors influencing net migration to the various US states. Concretely, this research obtained the following findings: (1) the seven variables ‐‐ the average rate of net migrants of 2002–2005, Medicaid, federal aid, employment rate, non‐poverty population rate, and SSI subsidy ‐‐ all significantly affected (p < 0.01 or p < 0.05) net migration in 2006; (2) the main influences on net migration for the various states are, from highest to lowest, social network, economic, and welfare factors. More specifically, a better explanation is that, through the social network factor, economic and welfare factors exert an increased influence on the net number of migrants; and (3) as for the influence of social network factors on the number of net migrants, the social network factor for the previous year was found to best explain domestic migration flows, while the social network factor for the previous three‐to‐four years best explained international migration flows.  相似文献

We develop a regression decomposition technique for hazard rate models, where the difference in observed rates is decomposed into components attributable to group differences in characteristics and group differences in effects. The baseline hazard is specified using a piecewise constant exponential model, which leads to convenient estimation based on a Poisson regression model fit to person-period, or split-episode data. This specification allows for a flexible representation of the baseline hazard and provides a straightforward way to introduce time-varying covariates and time-varying effects. We provide computational details underlying the method and apply the technique to the decomposition of the black-white difference in first premarital birth rates into components reflecting characteristics and effect contributions of several predictors, as well as the effect contribution attributable to race differences in the baseline hazard .  相似文献

Abstract

Interest group conflict, power, and values have been prominent in recent attempts to analyze law as social control. The role of fact beliefs in creating, interpreting and administering legal norms has been relatively neglected, especially in the few efforts toward theories of law in society. Both fact beliefs and value beliefs are here related to legal norms, and also to group interests, power and conflict. Law is conceived of as the formal social control of the political state, a definition that does not at all require acceptance of Austin's view of law as commands of the sovereign. The forced choice between power elite and structural-functional theories is avoided, since law operates in a wide variety of power situations. The subjective meanings of interest group actions directed toward legal norms are seen as consisting of value and fact beliefs, an approach of particular promise in analyzing law and social change.  相似文献

Numerous studies suggest spirituality and subjective well-being (SWB) are positively associated. However, critics argue that popular spirituality instruments—including the Daily Spiritual Experiences Scale (DSES)—contain items that conflate religiosity/spirituality (R/S), prosociality and SWB. Advocates of the DSES retort that, despite this concern, the available evidence confirms a single underlying factor. The current paper evaluates the DSES’s development, factor structure, reliability and convergent and predictive validity using a community sample. Despite the full DSES scale’s excellent internal reliability, two related factors—theism and civility—are identified. Both scales are reliable and converge meaningfully with related R/S measures. As expected, given previous findings, the full DSES scale predicts higher SWB yet the two subscales display divergent associations. This finding offers new insights into the DSES and raises questions about the claimed belief-as-benefit effect.  相似文献
