Abstract

This case study focuses on user research that was conducted to enhance our users’ ebook discovery experience. We took an outward-facing approach by seeking the users’ perspectives. We wanted to know: How do users find ebooks? How do they perceive multiple records for the same title? Would users find additional metadata useful, such as download availability, file format, and chapter titles? We coordinated guerilla usability testing in our library lobby, inspired by low-overhead, high-impact user experience work at other academic libraries. The resulting data gave us a much-needed new perspective of ebook usage that supplements what we already know from our day-to-day work.  相似文献

ObjectiveTo undertake a systematic review of the literature to determine whether Asian ethnicity is an independent risk factor for severe perineal trauma in childbirth.MethodOvid Medline, CINAHL, and Cochrane databases published in English were used to identify appropriate research articles from 2000 to 2010, using relevant terms in a variety of combinations. All articles included in this systematic review were assessed using the Critical Appraisal Skills Programme (CASP) ‘making sense of evidence’ tools.FindingsAsian ethnicity does not appear to be a risk factor for severe perineal trauma for women living in Asia. In contrast, studies conducted in some Western countries have identified Asian ethnicity as a risk factor for severe perineal trauma. It is unknown why (in some situations) Asian women are more vulnerable to this birth complication. The lack of an international standard definition for the term Asian further undermines clarification of this issue. Nevertheless, there is an urgent need to explore why Asian women are reported to be significantly at risk for severe perineal trauma in some Western countries.ConclusionCurrent research on this topic is confusing and conflicting. Further research is urgently required to explore why Asian women are at risk for severe perineal trauma in some birth settings.  相似文献

Prior research on Mexican migration has shown that social networks and economic incentives play an important role in determining migration outcomes. We use experimental data from PROGRESA, Mexico's primary poverty-reduction program, to evaluate the effects of conditional cash transfers on migration both domestically and to the United States. Our study complements a growing body of literature aimed at overcoming longstanding hurdles to the establishment of causal validity in empirical studies of migration. Analysis based on the data collected before and after the program's onset shows that conditional transfers reduce U.S. migration but not domestic migration. The data also enable us to explore the role of existing family and community migration networks. The results show that migration networks strongly influence migration, but that the effect of conditional transfers on migration is apparently not mediated by existing migration network structures. Our results suggest that conditional transfers may be helpful in managing rural out-migration, particularly to the United States.  相似文献

Economic uncertainty is typically stressful and conflict-inducing for couples. The findings from the current study, however, suggest that economic uncertainty can also strengthen marriages. The sample included 82 Latino and Caucasian married couples. The couples engaged in a stressful conversation about their economic uncertainty in the wake of the Great Recession. Many of the couples were resilient and even grew from their experiences with the recession. The couples’ resilience and risk when talking about financial uncertainty and stress were revealed in four communicative pathways: unifying, thriving, pragmatic and at-risk. These communicative patterns predicted self-reported and physiological stress, mental health indices and divorce proneness. In general, unified/thriving couples had higher levels of psychological well-being and less self-reported stress, anxiety, and divorce proneness compared to pragmatic and at-risk couples.  相似文献

Objective: To help clarify the effect of gender on the bidirectional relationship between alcohol use and strenuous physical activity in college students. Participants: Five hundred twenty-four (52% female) college students recruited in August 2008 and 2009 and followed up in April 2009 and April 2011, respectively. Methods: Participants reported their alcohol use and strenuous physical activity on 2 occasions (baseline and follow-up) spaced approximately 1 or 2 years apart. Results: For females, alcohol use quantity at baseline was associated with increased strenuous physical activity at 1- and 2-year follow-ups, and alcohol use frequency at baseline was associated with decreased strenuous physical activity at 2-year follow-up. For males, alcohol use frequency at baseline predicted decreased strenuous physical activity at 1-year follow-up. Conclusions: Gender differences may be explained from an eating disorders perspective such that women use physical activity as a compensatory strategy to combat potential weight gain from calories consumed during alcohol use.  相似文献

Stalking is relatively common yet little is known of the longer-term health effects of stalking. Using the National Violence Against Women survey, we estimated lifetime stalking victimization among women and men, ages 18 to 65, identified correlates of being stalked, and explored the association between being stalked and mental and physical health status. With a criterion of being stalked on more than one occasion and being at least "somewhat afraid," 14.2% of women and 4.3% of men were victims. Among those stalked, 41% of women and 28% of men were stalked by an intimate partner. Women were more than 13 times as likely to be "very afraid" of their stalker than men. Negative health consequences of being stalked were similar for men and women; those stalked were significantly more likely to report poor current health, depression, injury, and substance use. Implications for victims, service providers, and the criminal justice system were reviewed.  相似文献

The effects of different sales strategies on consumer product evaluation were investigated. It was expected that direct product experience could decrease economic product valuation. Experiments 1 and 2 studied the effects of product trials and money-back guarantees on consumer willingness to pay (WTP). It appeared that WTP was significantly lower after a product trial than with a money-back guarantee or normal sale. In Experiment 3 a structural equation model showed that product trials had a positive effect on attitude toward the product. Also, a negative effect on WTP was found when the effect was measured directly, but a positive effect when the effect was measured indirectly (through attitude).  相似文献
