This study explores how online publics are engaging with organizations by creating and sharing brand-related content online, outside corporate-controlled communication environments. This research employs a quantitative content analysis of memes shared on the social networking site Imgur to reveal how user-generated content conveys meaning about organizations. The analysis reveals brand-centric memes are generally classified as orphan memes, or memes that have distinct textual and visual characteristics separating them from established or emerging meme families. Memes about organizations are neither an overwhelming reflection of biting criticism or support, but rather a reflection of online public engagement with organizations that primarily use humor and textual brand features (or quiddities) to convey their commitment and satisfaction with the organization and unite meme families. 相似文献

Using behavioral self-regulation processes may facilitate exercise among older women with heart disease. Data from women in a heart disease-management program (n = 658, mean 73 years), was used to explore associations among exercise self-regulation components (i.e., choosing to improve exercise and observing, judging, and reacting to one's behavior) and exercise capacity. General linear models showed that choosing exercise predicted higher exercise self-regulation scores postprogram and 8 months later. In turn, these scores predicted greater improvements in exercise capacity concurrently and 8 months later. Interaction analyses revealed that the effect of self-regulation on exercise capacity was stronger among women who chose to work on exercise. 相似文献

This research examines land use change in Israel––an intriguing but understudied setting with regard to population–environment
dynamics. While Israel is fairly unique with regard to its combined high levels of economic prosperity and high population growth, this case study has relevance for developed countries and regions (like the south and southwest regions
of the USA) which must balance population growth and urban development with open space conservation for ecosystem services
and biological diversity. The population–land development relationship is investigated during the period from 1961 to 1995
at three spatial scales: national, regional (six districts), and local (40 localities). There is a positive correlation between
population growth and land development rates at the national scale, and while remaining positive, the strength of the relationship
varies greatly at regional and local scales. The variation in population–land use dynamics across scales is used to garner
insight as to the importance of geography, policy and historical settlement patterns. 相似文献

We explore whether the growing labor force attachment of married women has increased the importance of the wife’s characteristics
in determining the household migration decision. To the contrary, we find that surprisingly little changed between 1960 and
2000. Wives were a weak determinant of family migration over the entire period. Our results suggest that it is difficult to
balance two careers simultaneously, with households finding it optimal to focus primarily on the husband’s career rather than
settling for significantly inferior labor market outcomes for each spouse. 相似文献

Previous research has revealed a significant bivariate relationship between anabolic-androgenic steroid (AAS) use and reduced condom use among adolescent boys. However, to date, no known studies have explored the psychological mechanisms that may explain this relationship. Thus, the current study sought to examine two possible mediators in the association between AAS and condom use: depressive symptoms and substance use. Data were extracted from a nationally representative sample of U.S. adolescents. Participants were 3,780 U.S. high school boys who responded to self-report items assessing a number of health behaviors, including symptoms of depression, substance use, AAS use, and use of condoms during their most recent act of intercourse. Both depression and substance use were significant mediators in the relationship between AAS and condom use. However, when these effects were contrasted, the indirect effect of substance use was significantly stronger in magnitude than the effect of depression. Although AAS use was associated with sexual risk behaviors among adolescent boys, significant variance in this relationship was accounted for by elevated levels of depression and substance use, with substance use demonstrating a particularly salient pathway. 相似文献

We propose a procedure for dividing a set of indivisible items between two players. We assume that each player’s preference over subsets of items is consistent with a strict ranking of the items, and that neither player has information about the other’s preferences. Our procedure ensures an envy-free division—each player receives a subset of items that it values more than the other player’s complementary subset—given that an envy-free division of “contested items,” which the players would choose at the same time, is possible. We show that the possibility of one player’s undercutting the other’s proposal, and implementing the reduced subset for himself or herself, makes the proposer “reasonable,” and generally leads to an envy-free division, even when the players rank items exactly the same. Although the undercut procedure is manipulable and its envy-free allocation may be Pareto-inferior, each player’s maximin strategy is to be truthful. Applications of the procedure are discussed briefly. 相似文献

Non-market economy including volunteer work is often ignored in estimations of the shadow economy because no money changes hands. Whilst volunteers stricto sensu are not paid for their activities, a tendency is noted that legal frameworks do allow for reimbursement for actual expenses incurred. However, if the latter receive reimbursements beyond the scope of regulations and labour law this can also be regarded as undeclared work. In this article, the size and motives of this type of undeclared work in non-profit sports clubs in Flanders (Belgium) are explored. As this kind of informal work, by its nature, is difficult to measure, a mixed method approach was used. The results show that at least 10% of volunteers can be considered as undeclared workers. The tax and social security contribution burdens are considered as the main causes for this undeclared work. It is argued that a new employment status for paid volunteers in sports is necessary to guarantee the provision of qualitative sports services. 相似文献

Friends are among the most influential social forces affecting adolescent behavior, yet little work has focused on the influence of friends on the decision to apply to college. Using data from the senior cohort of the Texas Higher Education Opportunity Project, we employed propensity score matching with sensitivity analyses to investigate links between having college-oriented friends and applying to college. We found that college-oriented friends increased the likelihood of applying to any college and to 4-year colleges, both for White and Latino students. However, Latino students benefited less from college-oriented friends compared to White students. Our findings suggest that college-choice models should more directly account for the influence of friends in applying to college, taking account of racial and ethnic differences, and future research should explore why Latino students benefit less. 相似文献

The operating microscopes may be a significant cause of fatigue and discomfort in surgeons. The need for the microscope to be placed over the operating field forces surgeons to remain at the microscope's eyepieces at an uncomfortable posture for the entirety of the surgery. This study compared the effects on microsurgical task performance for four visualization methods: a monocular microscope, a binocular microscope, a three-dimensional (3D) flat-panel television display and a two-dimensional (2D) flat-panel television display. Eleven subjects each performed two microsurgical tasks and their performance was documented by video camera. The statistical analysis performed indicated utilization of the microscope as a visualization method increased subject performance. No significant difference in performance between the 2D and stereoscopic visualization methods. 相似文献
