This article addresses theoretical issues concerning differentiation and class formation using North American data. It explores how socio‐economic characteristics vary and impact survival in agriculture. The study is based on panel data collected from a sample of smallholders in three Piedmont North Carolina counties. Factor analysis reveals five major dimensions of differentiation: scale, household labour, off‐farm family labour and income, demographic characteristics, and land tenure. An index of propensity to survive in agriculture, constructed from three waves of panel data is regressed upon five indices measuring the underlying dimensions of differentiation. Land tenure manifests a statistically significant net effect on survival in agriculture. These empirical results support theoretical arguments in favour of integrating analyses of socio‐economic and demographic differentiation in the study of agricultural enterprises.  相似文献

At 17%, women represent a significant proportion of all offenders under criminal justice supervision in the US. Drawing on the findings from their report, “Gender-Responsive Strategies: Research, Practice, and Guiding Principles for Women Offenders,” the authors maintain that public policy has ignored the context of women's lives and that women offenders have disproportionately suffered from the impact of ill-informed public policy. This discussion of the implications of gender within the criminal justice system is based on a simple assumption: responding to the differences between women and men in criminal behavior and to their antecedents is critical to gender-responsive policy. Building on the pathway theoretical perspective, we find that in addition to the gendered impact of the war on drugs, policy changes in welfare reform, housing, and other social policy arenas combine to create a disparate impact on drug abusing women and women of color. Key policy areas affecting the lives of women offenders and their children include welfare benefits, drug treatment, housing, education, employment, and reunification with children. We conclude that addressing the realities of women's lives through gender-responsive policy and programs is fundamental to improved outcomes at all criminal justice phases. A blueprint for gender-responsive policy development is described through six guiding principles and their policy implications.  相似文献

At the wheels of railroads and streetcars, the law of accidental personal injury, known as negligence, became a discrete body of law between 1870 and 1920. The defining component of negligence was "fault"–the notion that the individuals (injured and injurer) must have failed to act according to some minimal standard of caution. Theorists of the history of negligence have explained that the conduct of all was measured against what a "reasonable man" would have done under the circumstances. The author here challenges this fundamental assertion. Through trial records, lawyer's written arguments, and appellate opinions, she reconstructs the critical role of gender in shaping the law of accidental injury. As she argues, in 19th- and 20th-century America, injury was a gendered event. The fact that courts in these years held men and women to different standards of care undermines theorists' arguments that economic considerations drove the law of accidental injury. Moreover, the reification of gender nm in private law, in turn, vitally affected the experience of gender in turn-of-the-century America.  相似文献

Calibration is commonly used in order to specify a numerical computable general equilibrium model. As it involves the evaluation of model parameters on the basis of a single observation, there is a concern about the reliability of the results obtained from the model. A one-sector model for the Polish economy is specified and calibrated using various years as a benchmark equilibrium. Different assumptions are also made about some elasticity parameters. The model response is examined by simulating an increase in government expenditure. The results are quite robust to the choice of the base year but very sensitive to some elasticity parameters such as trade substitution elasticities.  相似文献

Multiple-item measures of self-reported offending typically provide the principal outcome measures for individual level research on the causes of crime and deviance. This article directs attention to the substantial problems presented by the task of forming composite scores for these measures, and it presents a possible solution to those problems. We consider scaling by means of the graded response model from item response theory (IRT) as a potential means of overcoming the shortcomings of traditional summative scaling and of obtaining valuable information about the strengths and weaknesses of our measures. We illustrate this strategy through a scale analysis of a fourteen-item, self-report measure of delinquency, using three years of data from the Monitoring the Future study, an annual national survey of high school seniors. The graded response model proves to be consistent with the data, and it provides results that address important substantive questions about self-report measures. The findings are informative about the strengths and weaknesses of alternative strategies for developing self-report instruments, indicating that there is little to be gained by making fine distinctions in the frequency of individual delinquent acts.  相似文献

This article examines the state of intensive family preservation services (IFPS) research. Using studies of IFPS in five states, this article seeks to establish whether IFPS can be regarded as an evidence-based practice, an increasingly important standard for publicly funded services. While reporting rates of repeat child maltreatment, the analysis uses placement rates as the main outcome measure and compares effect sizes using Cohen's arcsine transformation for data reported as proportions. Significant differences in rates of child out-of-home placement and repeat maltreatment were found in some studies, particularly for higher risk families. The findings also underscore the difficulty of identifying which families to serve (targeting), ensuring treatment fidelity, and employing rigorous and appropriate evaluation methods. Overall, additional research is needed to move IFPS from a promising practice to an evidence-based practice.  相似文献
