This study applies wavelet coherency analysis to examine the relationship between the U.S. per capita real GDP and six income inequality measures over the period 1917 to 2012. Wavelet analysis allows the simultaneous examination of correlation and causality between the two series in both the time and frequency domains. Our findings provide robust evidence of positive correlation between the growth and inequality across frequencies. Yet, directions of causality vary across frequencies and evolve with time. Evidence that inequality leads per capita real GDP at both high- and low-frequencies exists for the Top 1 and 10% measures of inequality with little evidence that real GDP per capita leads inequality. In the time-domain, the time-varying nature of long-run causalities implies structural changes in the two series. These findings provide a more thorough picture of the relationship between the U.S. per capita real GDP and inequality measures over time and frequency, suggesting important implications for policy makers.  相似文献

Science fiction (sf) does more than provide a fleeting moment of entertainment; it has many personal and social functions. In addition to offering audiences “romantic escapism” (Gerrold, 1996, pp. 5–6), sf also enables the “postulation of an alternative reality from which to contemplate this one” (Gerrold, 1996, pp. 5–6); as such, it is especially important “for groups which have had limited stakes in the status quo” (Jenkins, 1995, p. 242). To date, no research has been undertaken on the relationship between Australian queers and sf fandom. This article reports the findings of an online survey and explores the psycho-social features of Australian queer sf fans and why they like the genre. While the characteristics of this sample mirror those of Australian queers generally, they also have slightly higher rates of mental illness and are far more likely to state they have “no religion.” Furthermore, while enjoying the “sciency” (P10, bisexual woman) aspects of sf, Australian queers also like the “poignant metaphors for our own civilization” (P45, asexual man)  相似文献

This study examines whether social‐emotional difficulties associated with higher body weight vary across schools as a function of the school's weight climate. Weight climate, characterized by weight‐policing, was assessed indirectly by examining how strongly self‐reported weight predicts victim reputation within 26 ethnically diverse middle schools. Social‐emotional indicators included self‐reported loneliness, school belonging, and self‐esteem. In schools with stronger weight‐policing at seventh grade, loneliness was intensified by eighth grade among both girls (= 2,101) and boys (= 1,985) with higher weight. Similar effects were found for low self‐esteem among girls. Additionally, boys—regardless of their weight—reported lower sense of belonging in schools with stronger weight‐policing. The study offers a new method to estimate school weight climate, and the findings provide insights for interventions.  相似文献

Collaboration is an increasingly important topic in the publicadministration and management literatures. A preponderance ofstudies focuses on how managers can build trust between thegovernment and collaborative partners by means of behavioralattributes and managerial skill. In this article, the authorsuggests that stable institutions and local government structurefacilitate collaboration by allowing public managers to morecredibly commit in a policy arena. Using county data on open-spacepolicy, the author finds empirical support for the propositionthat county form of government, along with rules governing debtaccumulation and administrative commitment, increases the breadthof county collaboration in open-space protection.  相似文献

In drug development, a common choice for the primary analysis is to assess mean changes via analysis of (co)variance with missing data imputed by carrying the last or baseline observations forward (LOCF, BOCF). These approaches assume that data are missing completely at random (MCAR). Multiple imputation (MI) and likelihood-based repeated measures (MMRM) are less restrictive as they assume data are missing at random (MAR). Nevertheless, LOCF and BOCF remain popular, perhaps because it is thought that the bias in these methods lead to protection against falsely concluding that a drug is more effective than the control. We conducted a simulation study that compared the rate of false positive results or regulatory risk error (RRE) from BOCF, LOCF, MI, and MMRM in 32 scenarios that were generated from a 2(5) full factorial arrangement with data missing due to a missing not at random (MNAR) mechanism. Both BOCF and LOCF inflated RRE were compared to MI and MMRM. In 12 of the 32 scenarios, BOCF yielded inflated RRE compared with eight scenarios for LOCF, three scenarios for MI and four scenarios for MMRM. In no situation did BOCF or LOCF provide adequate control of RRE when MI and MMRM did not. Both MI and MMRM are better choices than either BOCF or LOCF for the primary analysis.  相似文献

This paper presents data on red squirrel road casualties recorded in the four-year period 1993–1996 within the National Trust reserve and adjacent suburban gardens of Formby, Lancashire, England. A total of 130 adults and six subadults were recorded as road traffic victims. Road casualties accounted for 65% of the recorded adult mortality (26.7% of the reserve total and 88% in the suburban habitat). Adult males were killed more frequently than females during the winter months. Road traffic deaths were highly seasonal with a clear peak in the autumn months (53.7% of all casualties). It is suggested that this may be related to seasonal variation in foraging behavior and to the abundance of natural and supplemental foods.  相似文献

Intercommunity variation in growth machine activities, including the manipulation of the business climate and vertical integration with state economic development programs, net migration, and land use change are examined using a sample of 96 small urban places. A panel design and key informant methodology, 1970–90, permit cross-sectional and longitudinal observation. Using regression analysis with appropriate statistical controls, the research indicates that growth machines, particularly those in affluent communities, do intensify land uses. The business climate also negatively affects changes in business and industrial land uses as well as net migration. Some local efforts may not affect growth until the subsequent decade. The research suggests that growth machine activities are intensifying and may be exacerbating social inequality between places, especially affluent residential communities and declining working-class communities in the old industrial belt.  相似文献

This study examined the relationship between accuracy and confidence on the Interpersonal Perception Task (IPT-15). This version of the IPT contains 15 brief, real-life scenes on videotape for which there are objectively correct answers to questions about status, intimacy, kinship, competition, and deception. A total of 241 participants were run in a 2 (high vs. low cognitive demand) × 2 (first impression vs. nonverbal cues strategy) × 2 (sex of participant) design. Overall, no significant relationship was found when accuracy scores were correlated with two between-participant measures of confidence. There was, however, a significant relationship within-participants between accuracy and confidence. Thus, participants' rated confidence for each of the 15 scenes did predict accuracy in judgments about the scenes. In addition, a 2 × 2 × 2 ANOVA on participants' transformed accuracy-confidence correlations revealed a small, significant effect of strategy. Specifically, the accuracy-confidence correlations were higher when participants were instructed to attend to specific nonverbal cues in making their judgments than when they were told to rely on their first impressions. Although there were no differences between men and women in either their accuracy or their accuracy-confidence correlations, men rated their confidence significantly higher than did women. The factors affecting the accuracy-confidence relationship and their role in automatic judgments are discussed.  相似文献

Social work programs must effectively meet the needs of their diverse lesbian, gay, bisexual, transgender, and queer (LGBTQ) student populations as well as effectively train all students to work with minority groups including the LGBTQ community. While many undergraduate and graduate social work programs provide open, supportive, and affirming experiences for LGBTQ students, there remain ongoing challenges related to hostility, stigma, heterosexism, and homophobia within classroom settings across programs in the US and Canada. This study examines classroom experiences of homophobia among 1,018 social work students. Qualitative data associated with three optional open-ended questions were analyzed utilizing grounded theory. Main qualitative findings identified several major themes associated with social work student experiences of homophobia in the classroom including: (1) Coming out; (2) Faculty inaction; (3) Implicit and explicit content; (4) Direct language and actions; and (5) Religious rationalizations and non-affirming positions. Conclusions and recommendations for social work education are discussed that center around creating safe and affirming classroom settings; the vital role of out faculty, students, and allies; impactful integration of diversity content within curricula, policies, and accreditation standards; ongoing training and mentorship; understanding the role of power and oppression; and a call to action among social work educators and the profession.  相似文献
