A prickly problem: developing a volunteer-friendly tool for monitoring populations of a terrestrial urban mammal,the West European hedgehog (<Emphasis Type="Italic">Erinaceus europaeus</Emphasis>)

Across Europe, hedgehogs (Erinaceus europaeus) appear to be in decline in both urban and rural landscapes. Current methods used to monitor urban populations are, however, associated with several potential limitations. In this study, we conducted hedgehog footprint-tunnel surveys in 219 residential gardens across Reading, UK between May–September in 2013 and/or 2014; gardens were surveyed for five continuous days. Single-species occupancy models were used to investigate factors influencing hedgehog occupancy and two-species occupancy models were used to estimate a species interaction factor (SIF) between hedgehogs and (a) badgers (Meles meles), (b) foxes (Vulpes vulpes) and (c) dogs (Canis familiaris). The five-day survey protocol was associated with a false-absence error rate of 0.1–0.4%, indicating that it was a reliable method for determining hedgehog presence; conversely, 34.7% of householders were not able to correctly predict hedgehog presence or absence. Hedgehogs were widely distributed across Reading, but detected in only 32–40% of gardens. None of the within-garden or outside-garden factors investigated significantly affected hedgehog occupancy in the single-species models, but the two-species models indicated that badgers (SIF?=?0.471?±?0.188), but not foxes (SIF?=?0.954?±?0.048) or dogs (SIF?=?0.780?±?0.228), negatively affected the presence of hedgehogs in gardens, although not significantly. Overall, footprint-tunnels represent a viable field method for monitoring urban hedgehog populations, however, other approaches are required to identify factors that make gardens “hedgehog friendly”.     

“I Just Want to Do God's Will:” Teaching Martin Luther King,Jr. as a Religious Leader

Teachers often respond to the perils of teaching about religion by simply avoiding the subject. An investigation of secondary lesson plans on three prominent Martin Luther King, Jr. websites reveals little attention to the ideology of the civil rights movement, especially those touching on religious ideas. Ignoring King's religious views risks fundamentally misrepresenting his identity, his ideology, and his motivation for nonviolence. Stride Toward Freedom: The Montgomery Story, King's 1958 account of the Montgomery Bus Boycott articulates three key features of the theological framework that inspired his activism: the spiritual motivation for his leadership, the ethical basis for his strategy of nonviolent direct action, and the theological understanding of human nature that undergirded his leadership and strategy. These points provide a useful model for introducing King's ideas in the classroom. The effort to intentionally and thoughtfully teach religion could contribute one step toward inculcating genuine tolerance among students. Civil discourse is not fostered simply by identifying core principles everyone shares but also through thoughtful, critical engagement with disparate ideas, including what are, for many people, the most heavily freighted ideas.

Determinants of motion picture box office and profitability: an interrelationship approach

Introduction  Producing and marketing motion pictures is notoriously risky, with only three out of ten movies breaking even and one becoming profitable at the box office. Extending knowledge on the factors that influence a movie’s box-office and on the interrelations between these factors can be seen as major contribution to aid in lowering the number of failures in the motion picture industry. The major aim of this study is to distinguish direct and indirect effects between potential success drivers and motion picture success by understanding the interrelationships among different determinants of movie success. Methods  Hypotheses are developed with regard to the relationships among a number of factors that have been shown to impact motion-picture box office as well as movie profitability. Applying path analysis, which allows a simultaneous testing of factor interrelations, the hypotheses are subsequently tested against a sample of 331 movies. Results and conclusion  The factors considered in the analysis explain a remarkable amount of a movie’s success. The findings improve the movie industry’s understanding of motion picture success because for the first time interrelationships between the various factors are considered, which enables the separation of direct and indirect (i.e., mediated) effects. By understanding different kinds of effects on movie success, studios are enabled to allocate budgets more effectively. In addition, the findings offer explanations for previous contrary findings of several factors’ influences on success.      

What Affects the Quality of Economic Analysis for Life‐Saving Investments?‡

Economic analysis of life-saving investments in both the public and private sectors has the potential to dramatically improve longevity and the quality of life, but only if the analyses on which decisions are based are done well. In this article, we analyze a data set that provides information on the content and quality of journal articles that measure the cost-effectiveness of life-saving investments. Our study is the first to provide a detailed multivariate analysis of factors affecting objective measures of quality. We also explore whether a series of recommendations by an expert panel convened by the U.S. Public Health Service affect the way analyses of specific life-saving investments are done. Our results suggest that four factors are positively correlated with an index we construct to measure analytical quality: (1) having at least one author affiliated with a university, (2) publication in a journal that has experience in publishing these analyses, (3) if the life-saving investment is located in the United States, and (4) if the analysis considers a measure of social costs or benefits. Somewhat surprisingly, a study's funding source and whether it is affiliated with industry are not significantly correlated with the quality index. Finally, neither time nor the panel guidelines had an impact on the index.     

‘My Grandfather Would Roll Over in His Grave’: Family Farming and Tree Plantations on Farmland*

Abstract In this paper we hypothesize that farmers with a stronger valuation of family farming will be more resistant to converting farmland to tree plantations. Our survey data analysis from 106 farmers in northern Alberta reveals that general opposition to trees on farmland is the strongest predictor of farmers' resistance to the establishment of poplar tree plantations on privately‐owned land. Valuation of family farming is the strongest determinant of resistance to trees on farmland. Among the potential intervening variables influencing support for tree plantations, including county, age, gender, number of children, and percent of income from farming, number of children and percent of income from farming had significant direct effects on valuation of family farming. This study suggests that economic incentives alone are unlikely to influence farmers' willingness to convert their land to non‐traditional uses, and that intergenerational transfer of land, and its relationship to valuation of family farming, deserves further attention in rural sociological scholarship.     

Mehr Arbeit,mehr Armut? Ausmaß und Hintergründe der Entkoppelung von Erwerbsarbeit und materieller Sicherheit von Alleinerziehenden im Ländervergleich

Labour market reforms implemented in recent years in a number of countries have aimed to increase participation rates among single parents in order to reduce the disproportionately high poverty rate and share of benefit recipients among them. However, our quantitative analyses based on EU-LFS and EU-SILC indicate that paid work has to some extent become dissociated from material security. Although participation rates among single parents rose in the five years before the financial and economic crisis, their risk of being in poverty remained the same or actually increased. This finding holds true for different types of welfare state, as the comparison between Germany, France, Sweden and the UK shows. The potential poverty-reducing effects of increasing labour market participation are clearly being weakened by certain counter-trends. Possible explanations, which apply to varying extents in the four countries, are declining market wages and reductions in social transfers. Moreover, previously latent material risks of lone parenting unfold with the modernisation of gender roles and the erosion of lone mothers ‘avant-garde’ role as working parents. This is a common challenge across countries which has so far not been addressed sufficiently by social and labour market policies.     

The long run consequences of unilateral divorce laws on children—evidence from SHARELIFE

Previous research has shown adverse effects of growing up under unilateral divorce laws on long-term outcomes of children. It remains an open question of whether these effects of early childhood conditions arise due to divorce laws raising the likelihood of parental marital disruption or whether unilateral divorce laws also affect children in intact marriages by changing intra-household bargaining. Using recently available data from SHARELIFE for 11 Western European countries, we address this question employing a difference-in-differences approach and controlling for childhood family structure and socioeconomic status. Like previous research, we find adverse effects of growing up under unilateral divorce laws on the well-being of children. This effect remains even when controlling for childhood variables. We conclude that unilateral divorce laws affect children by changing family bargaining in intact marriages.
