Family Structure, Community Context, and Adolescent Problem Behaviors

A number of models have been proposed to explain the relationship between family structure and adolescent problem behaviors, including several that consider parent-child relations, family income, stress, and residential mobility. However, studies have not explored whether the different types of communities within which families reside affect the association between family structure and problem behaviors. A community context model also suggests that the relationship between family structure and problem behaviors may be conditioned by community characteristics. The results of a multilevel regression model that used data from the National Educational Longitudinal Study (NELS; n = 10,286) indicated that adolescents from homes with a recently divorced mother, a mother and stepfather, a single mother, or a single father reported more problem behaviors regardless of the community context. Moreover, adolescents living in communities with a high proportion of impoverished residents, female headed households, or jobless males reported more problem behaviors irrespective of family structure.

The Individual-Level Determinants of German Party Membership

Why do citizens join German parties? Do specific attributes and abilities play a determinant role in participation in political parties? The German Party Membership Study of 2009 enables us to answer these questions. On the basis of the telephone survey, we will address these issues by way of a systematic comparison of current party members with fellow citizens who never joined a party. For the purpose of analysing the individual-level determinants of joining a party, we use fundamental explanatory approaches to political participation: The socioeconomic standard model, the social-psychological approach, and the general incentives model. The results of our analyses clearly show that social-psychological attributes best explain the decision to join a party. Nevertheless, the findings for the determinants in both the socioeconomic standard model and the general incentives model complete the picture of citizens who are party members.     

Tetracycline-like fluorescence in buried human skeleton parts

Some ubiquitous soil-living micro-organisms are producing tetracycline-like fluorescences in skeletal remains. For this reason, the possibility of using tetracycline fluorescences in dating or allocating displaced skeletal parts is severely limited.     

Understanding Mission Expansion in the Federal Home Loan Banks: A Return to Behavioral-Choice Theory

Congress established the Federal Home Loan Banks (FHLBs) in 1932 to pursue the public purpose of homeownership. Recently, three views of their mission have emerged; one is that their purpose is to help small banks to remain viable. Why did their mission expand in this direction? We argue that mission expansion is a process that is better understood in terms of behavioral choice than public choice. Change began when expert attention was directed to small banks in rural areas and officials innovated within the existing rules to address their needs. Recognizing the FHLBs' usefulness, community bankers sought a more fundamental change in their practice. Responding to the general interest in preserving small banks' viability, legislative entrepreneurs advanced permissive rule changes. These were implemented to different extents in individual FHLBs in response to local needs. The case illustrates the usefulness of the behavioral‐choice paradigm for understanding change in public agencies and suggests legitimacy for mission change and the value of maintaining publicly directed administrative capacity.     

Statistical evaluation of the evidential value of human hairs possibly coming from multiple sources

A concept of the mathematical evaluation of human hair evidence is derived. This concept can be realized in a special computer program, the output of which is an incrimination probability. The problems of not knowing the true number of sources and the correct partition of hairs corresponding to their sources are solved from the point of view of avoiding an unjustified incrimination.     

On the measurement of low self-control in Add Health and NLSY79

Limited attention has been devoted to the dimensionality of the low self-control scales commonly constructed in two nationally representative datasets routinely used to test self-control theory (SCT) – Add Health and NLSY79. We assess the measurement properties of the low self-control scales by comparing a series of exploratory and confirmatory models that are appropriate for the categorical nature of the observed items, including unidimensional, correlated factors, second-order factor, and bifactor models. Additionally, based on these results we explore the predictive validity of the respective scales on adolescents’ delinquent behavior. The results indicate that the low self-control scales in these data have acceptable levels of internal consistency but do not represent unidimensional latent factors. Rather, scales are best represented by a second-order factor structure. When measured this way, our Add Health scale is associated with delinquency in a cross-sectional context and our NLSY79 scale predicts delinquency longitudinally. This study reveals that low self-control is best conceptualized as a multidimensional construct within these data. The results of this study provide guidance to researchers measuring low self-control in either dataset (or other data sources) and inform the larger SCT measurement literature.
