The Enforcement of the Treaty of Versailles, 1919-1923

This paper uses the episode of the Kapp putsch in March 1920 to isolate and analyze a number of high policy themes that dominated the period from the signature of the Treaty of Versailles through to the Franco-Belgian invasion of the Ruhr. These included: the questions of what mechanisms existed to enforce the treaty; the sanctions available to the victorious governments to enforce their will; the position and problems of the German government; the relationship and suspicions existing between Britain and France and the differing aims, ambitions, and approaches of the major participants.     

Examining the empirical relationship between prison crowding and inmate misconduct: A meta-analysis of conflicting research results

Incarceration rates in the United States dramatically increased over the past several decades. This trend has drawn significant academic attention to prison overcrowding and its potential effect on inmate misconduct. The empirical relationship between inmate misconduct and overcrowding, however, is less than clear. To be sure, studies indicating positive, negative, and null relationships can all be found in the literature. The current research subjects this body of literature to a meta-analysis in an effort to: (1) clarify the direction and strength of the relationship between overcrowding and rates of prison misconduct across all studies, and (2) to uncover the degree to which variation in research outcomes can be attributed to methodological differences across studies. Results indicate that prison crowding has little substantive impact on inmate misconduct. Implications of the findings are discussed in detail.     

Taking the Keys from Grandpa

Recent highly publicized traffic accidents involving older drivers have led to renewed interest in state policies and administrative practices that award and renew drivers’ licenses in the American states. Because the probability of traffic accidents is linked to the medical conditions that are more prevalent among the elderly, and because the number of older drivers is expected to rise over the next several decades, one might expect that this will be an increasingly important policy issue. This article discusses variations that are observed across states in law and administrative practice. A longitudinal analysis of data on crashes involving elderly drivers in fifteen states indicates that crash rates are directly related to the length of the renewal cycle for older drivers and inversely related to the stringency of testing at renewal. It is also likely that states requiring physicians to report conditions that would impair driving will experience lower crash rates. A secondary analysis of policy impacts on the licensing rates is not conclusive, a finding that is attributable to inaccuracies in the reported numbers of licensed drivers.     

Relating Seasonal Hunger and Prevention and Coping Strategies: A Panel Analysis of Malawian Farm Households

Relative to chronic hunger, seasonal hunger in rural and urban areas of Africa is poorly understood. This paper examines the extent and potential correlates of seasonal hunger in Malawi using panel data from 2011–2013. We find that both urban and rural households report seasonal hunger in the pre-harvest months. Certain strategies to smooth consumption, including crop storage and livestock ownership, are associated with fewer months of hunger. In addition, we find that Malawian households that experience seasonal hunger harvest their crops earlier than average – a short-term coping mechanism that can reduce the crop’s yield and nutritional value, possibly perpetuating hunger.     

Neighborhood challenges to economic development

This article analyzes neighborhood-based development challenges. The article examines six explanations for such challenges: use value, social status, growth, economic and fiscal, governmental structure, and suburban. Using data derived from several sources (survey, Census, I. C.M.A.), the results indicate that cities with higher housing values and reform government structures are more likely to have neighborhood-based development challenges. The analysis is extended to investigate successful neighborhood-based development challenges. These results indicate that a city's poverty rate depresses the potential for successful challenges and that challenges are more likely to be successful in central cities. Finally, the analysis indicates that those cities in which neighborhood groups are motivated by the desire to protect housing values are more likely have successful development challenges.     

Land reforms and voluntary resettlement: household participation and attrition rates in Malawi

ABSTRACT

This paper examines the factors influencing household participation in and withdrawal from a World Bank-funded voluntary resettlement scheme moving 15,000 low-income farming households within and across rural districts in Malawi. Using a survey of 203 beneficiary households, focus groups and in-depth interviews, we identify a lack of access to land and conflict over land in the area of origin as salient participation factors in resettlement, while withdrawal factors include lower access to infrastructure and poor soil quality in resettlement areas. We also highlight limited prior awareness of actual conditions in resettlement areas, low and biased participation in the decision to move, a greater desire for formal land titles due to loss of customary entitlement as a result of resettlement, and widespread ambiguity and confusion over titles for resettled plots. In this context, we point to a pattern of ‘negative resettlement’, in which households remain resettled despite major grievances, for lack of an alternative option, contrasting with ‘positive resettlement’, where households remain by choice. We suggest that intra-district resettlement is more likely to be successful than inter-district resettlement when there is a risk of informed consent deficiency. These findings point to the relative failures of this particular resettlement scheme, and suggest possible improvements for land redistribution schemes from agro-industrial projects to poor households.     

Empirical analysis of the STR profiles resulting from conceptual mixtures

Samples containing DNA from two or more individuals can be difficult to interpret. Even ascertaining the number of contributors can be challenging and associated uncertainties can have dramatic effects on the interpretation of testing results. Using an FBI genotypes dataset, containing complete genotype information from the 13 Combined DNA Index System (CODIS) loci for 959 individuals, all possible mixtures of three individuals were exhaustively and empirically computed. Allele sharing between pairs of individuals in the original dataset, a randomized dataset and datasets of generated cousins and siblings was evaluated as were the number of loci that were necessary to reliably deduce the number of contributors present in simulated mixtures of four or less contributors. The relatively small number of alleles detectable at most CODIS loci and the fact that some alleles are likely to be shared between individuals within a population can make the maximum number of different alleles observed at any tested loci an unreliable indicator of the maximum number of contributors to a mixed DNA sample. This analysis does not use other data available from the electropherograms (such as peak height or peak area) to estimate the number of contributors to each mixture. As a result, the study represents a worst case analysis of mixture characterization. Within this dataset, approximately 3% of three-person mixtures would be mischaracterized as two-person mixtures and more than 70% of four-person mixtures would be mischaracterized as two- or three-person mixtures using only the maximum number of alleles observed at any tested locus.     

Systematic differences in electropherogram peak heights reported by different versions of the GeneScan software

DNA profiling using STRs on the 310 and 3100 Genetic Analyzers routinely generates electropherograms that are analyzed with the GeneScan software available from the instrument's manufacturer, Applied Biosystems. Users have been able to choose from three different smoothing options that have been known to result in significant differences in the peak heights that are reported. Improvements in the underlying algorithm of the most recent version of the software also result in significant and somewhat predictable differences in peak height values. Laboratories that have performed validation studies using older versions of GeneScan should either reanalyze the data generated in those validation studies with the newest version of the software or otherwise take into consideration the systematically higher peak height values obtained as they begin following the recommendation of the manufacturer and use the new algorithm.
