ABSTRACT Employee financial wellness programs (EFWPs) are a new practice that may promote financial inclusion by making it easier for workers with low- and moderate-incomes (LMI) to access financial services. We examine the strengths and limitations of workplace financial counseling, credit-building services, and small-dollar loans, and describe community collaboration to promote employee financial wellness. Findings suggest that these services are reaching a population that experiences financial exclusion, though evidence is mixed concerning how these services help workers with LMI resolve key financial challenges. Community collaboration focused on employee financial wellness presents opportunities to advocate for higher wages and better benefits. 相似文献

AbstractObjective: Examine receptivity and motivation to use/quit tobacco among college students after viewing Truth ads. Participants: Random sample of 10,000 college students invited to complete online survey February 2016 (8.5% response rate). Methods: Quasi-experimental. Participants (N?=?854) watched four ads and answered survey items for each ad. Results: Students rated ad receptivity and decreased motivation to use tobacco higher for the Catmageddon ad than the others. Regardless of ad, men and current cigarette smokers reported lower receptivity. Younger age was associated with lower motivation to use tobacco for all ads. Tobacco users reported greater motivation to quit with the Catmageddon ad. Conclusions: College students were receptive to the Truth ads, and many indicated lower motivation to use tobacco. Men, older college students, and current cigarette smokers were less receptive to the ads, reinforcing the need to develop tailored campaigns to reach these subgroups. 相似文献

One of the most dynamic and fruitful areas of current health‐related research concerns the various roles of the human microbiome in disease. Evidence is accumulating that interactions between substances in the environment and the microbiome can affect risks of disease, in both beneficial and adverse ways. Although most of the research has concerned the roles of diet and certain pharmaceutical agents, there is increasing interest in the possible roles of environmental chemicals. Chemical risk assessment has, to date, not included consideration of the influence of the microbiome. We suggest that failure to consider the possible roles of the microbiome could lead to significant error in risk assessment results. Our purpose in this commentary is to summarize some of the evidence supporting our hypothesis and to urge the risk assessment community to begin considering and influencing how results from microbiome‐related research could be incorporated into chemical risk assessments. An additional emphasis in our commentary concerns the distinct possibility that research on chemical–microbiome interactions will also reduce some of the significant uncertainties that accompany current risk assessments. Of particular interest is evidence suggesting that the microbiome has an influence on variability in disease risk across populations and (of particular interest to chemical risk) in animal and human responses to chemical exposure. The possible explanatory power of the microbiome regarding sources of variability could reduce what might be the most significant source of uncertainty in chemical risk assessment. 相似文献

ABSTRACTLoneliness negatively affects young and older adults. Intergenerational activities foster social connectedness. Using quantitative and qualitative methods, this study explored which intergenerational activities are most enjoyable for college students and retirement community residents. Demographics, loneliness, enjoyment, conversation level, and type of activity were analyzed. The enjoyment and conversation variables were positively correlated (r = .59, p < .001) which was supported by participants’ narratives. Both populations most enjoyed the activities with higher conversation levels, with the first being committees, followed by meals, one on one activities, and transportation. Retirement communities and universities should promote intergenerational activities, which include meaningful conversations. 相似文献

We construct a quantitative equilibrium model with firms setting prices in a staggered fashion and use it to ask whether monetary shocks can generate business cycle fluctuations. These fluctuations include persistent movements in output along with the other defining features of business cycles, like volatile investment and smooth consumption. We assume that prices are exogenously sticky for a short time. Persistent output fluctuations require endogenous price stickiness in the sense that firms choose not to change prices much when they can do so. We find that for a wide range of parameter values, the amount of endogenous stickiness is small. Thus, we find that in a standard quantitative model, staggered price‐setting, alone, does not generate business cycle fluctuations. 相似文献

Carol Cramer and Ellen Daugman of Wake Forest University discussed faculty attitudes toward ebooks in the library collection. Cramer and Daugman shared communication strategies based on their experience balancing the print book preferences of some faculty with the budgetary and collection development needs of the library. 相似文献

Due to growing work-family demands, supervisors need to effectively exhibit family supportive supervisor behaviors (FSSB). Drawing on social support theory and using data from two samples of lower wage workers, the authors develop and validate a measure of FSSB, defined as behaviors exhibited by supervisors that are supportive of families. FSSB is conceptualized as a multidimensional superordinate construct with four subordinate dimensions: emotional support, instrumental support, role modeling behaviors, and creative work-family management. Results from multilevel confirmatory factor analyses and multilevel regression analyses provide evidence of construct, criterion-related, and incremental validity. The authors found FSSB to be significantly related to work-family conflict, work-family positive spillover, job satisfaction, and turnover intentions over and above measures of general supervisor support. 相似文献

在19世纪晚期技术革命发生前,中国出版业的类型出现了重大变化,时间上主要是乾隆晚期、嘉庆和道光年间(1796-1850),即19世纪上半叶。在19世纪晚期"古腾堡式的机械印刷"传入上海时,机械化出现了,而在此之前正发生四种变化,它们导向的正是所谓文学现代性的后期标志。这四种变化包括小说的产量、发行方式、小说中表现的国际意识以及小说预期的读者构成。这些趋势的出现早于 19世纪晚期印刷技术革命,也早于 20世纪初期教育和文学生活中的变化。这表明在试图定义文学现代性时,必须既关注突然的外部影响或内部革命造成的因果变化的力量,也要关注连续性。 相似文献
