The squatting facet on femora of West Coastal Indian population

104 out of 108 adult femora from the West Coastal region of India show a distinct identifiable squatting facet on their popliteal surface. The data on such features are reviewed and its relevance to medico legal and anthropological science is discussed.     

A Note on the Use of County-Level UCR Data

County-level crime data have major gaps, and the imputation schemes for filling in the gaps are inadequate and inconsistent. Such data were used in a recent study of guns and crime without considering the errors resulting from imputation. This note describes the errors and how they may have affected this study. Until improved methods of imputing county-level crime data are developed, tested, and implemented, they should not be used, especially in policy studies.

江苏环境库兹涅兹曲线形状研究——基于面板数据模型

该文分析了江苏省1999年至2009年各市GDP数据与各市环境污染三废数据的关系,提出江苏省环境污染情况并不完全符合环境库兹涅兹曲线。该文采用面板模型对苏南、苏中、苏北的三废污染数据与经济增长水平的数据的关系曲线进行分析描绘,结果发现在江苏三大区域九种经济与三废污染的关系曲线形状中,有的呈现“N”型,有的呈现“-”型,有的呈现“S”型,总体并无特定规律。研究结果表明,江苏省经济发展情况与三废污染之间有其自身的特点,因此,在经济发展过程中要采取切合实际的措施,在推动经济发展的同时注意保护环境。     

Does social capital increase public support for economic globalisation?

The dominant explanation of public attitudes vis‐à‐vis economic globalisation focuses on re‐distributional implications, with an emphasis on factor endowments and government‐sponsored safety nets (the compensation hypothesis). The empirical implication of these theoretical arguments is that in advanced economies, on which this article focuses, individuals endowed with less human and financial capital will be more likely to experience income losses. Hence they will oppose economic openness unless they are compensated by the government. It is argued here that including social capital in the analysis can fill two gaps in explanations relying on factor endowments and the compensation hypothesis. First, generalised trust – one key aspect of social capital – constitutes a personal endowment alongside human and financial capital. Second, structural social capital – another key aspect of social capital – can be regarded as a nongovernmental social safety net that can compensate for endowment‐related disadvantages of individuals. Both aspects of social capital are expected to contribute, for distinct reasons, to more positive views on economic openness. The empirical testing relies on survey data for two countries: Switzerland and the United States. For both countries, the results indicate that generalised trust has a strong, positive effect on public opinion of economic globalisation, whereas structural social capital has no effect.     

Comparing Self-Report to Official Measures of Inmate Misconduct

Studies have revealed systematic measurement errors in self-report data on crime and deviance resulting from poor recall and/or underreporting by certain groups of respondents. Official crime data have also been criticized, but for different reasons (e.g. gross underestimations of less serious offenses). Very similar observations have been made in studies of inmate crime (misconduct committed by prison inmates). Despite these criticisms, official data on inmate misconduct continue to be the most frequently used data in related studies. This study compared self-report and official data on inmate assaults, property thefts, and drug offenses for samples of inmates from 46 correctional institutions for adults in Ohio and Kentucky. Findings revealed that officially recorded misconduct underestimates the total volume of inmate crime. Analyses designed to uncover sources of the divergence between self-reported misconduct and officially recorded misconduct revealed far more consistencies than differences in the magnitude of inmate and facility effects on the different types of offenses. A few important differences did emerge in the magnitude of effects such as amount of time served (at the individual level) and facility population size (at the aggregate level).
