Family contexts of pubertal timing

This study examined the influence of pubertal timing upon family interactions in normal and psychiatric adolescent samples. An important feature of our approach is its emphasis upon micro-analysis of family behaviors (individual speeches) and family processes (theoretically specified speech pairings). Rather than assume that global family patterns (e.g., power) shift in response to pubertal changes, we follow how types of speeches and speech sequences are associated with different pubertal timing. Using the previously constructed family coding system, the Constrainig and Enabling Coding System, we found that on-time adolescents and their parents differed from both off-time groups (early or late). These results are discussed in terms of current implications and suggestions for future research.An earlier version of this paper was presented at the SRCD Study Group on Timing of Maturation, October, 1983, at the Education Testing Service, Princeton, NJ.

Searching for Symptoms of Political Shirking: Congressional Foreign Travel

Despite the hypothesized propensity for shirking to marklegislative institutions, the evidence is rather equivocal;moreover, most of the research has focused exclusively onlegislator voting, thereby constraining whatevergeneralizations might emerge. The purpose of this paper is tocontribute to the debate over the question of politicalshirking by extending the range of phenomena examined toinclude congressional foreign travel. Our analysis providesevidence that opportunism is a problem in Congress. We findthat last-period problems have arisen in the area of foreigntravel, and that increased scrutiny to the problem on the partof Congress only shifted consumption patterns, i.e.,legislators began taking foreign junkets near, but not at theend of, their legislative careers. Not all foreign travelshould be construed as worthless junketing since there isstrong evidence that some foreign travel is related tomembers' responsibilities on congressional committees.     

Criminal justice and ethical ideology: an exploration of a loyalty-truthfulness dilemma

The notion of loyalty is well established in the criminological literature pertaining to ethics, ethical decision making, and ethical and ideological orientations. The present research addresses the topic of ethics and loyalty in an attempt to address three research questions germane to these areas within criminal justice and criminology. Using two samples equivalent in characteristics other than academic major, this research examines: (1) what impact gender, college major, and the ethical perspective of the observer and the nature of the actor’s action have upon the observer’s attitude toward the action (specific act of deception/truth); (2) what impact gender, college major, and the ethical perspective of the observer and the nature of the actor’s action have upon the observer’s perception of the social attractiveness of the deceiver; and (3) what impact gender, college major, the ethical perspective of the observer, and the nature of the actor’s action have upon the observer’s perception of the task attractiveness of the deceiver. Using a vignette design in this exploratory research, attempts are made to shed light on the impact of gender, major (criminal justice v. others), and ethical orientation on perceptions of an actor confronted with an ethical dilemma of loyalty versus disloyalty involving deception.     

Evaluating the discriminating power of amino acid ratios on distinguishing dark colored hair samples

Human hairs are one of the most commonly encountered items of trace evidence. Currently, conventional methods for hair analysis include microscopic comparison and DNA analysis (nuclear and mitochondrial). Each approach has its own drawbacks. Hair proteins are stable and offer an alternative to DNA testing, as demonstrated with proteomics for distinguishing humans. However, proteomics is complicated and requires identifying peptides to remain intact following harsh sample preparation methods. Alternatively, the actual amino acid content of a hair sample may also offer important identifying information and actually requires proteins and peptides to be broken down completely rather than remaining intact. This study evaluated the discriminating power of using hair amino acid ratios to differentiate hair samples from 10 unrelated individuals with dark colored hair. Hair proteins were digested, derivatized, and analyzed using gas chromatography–mass spectrometry. Amino acid ratios were calculated for each individual and comparisons using ANOVA and post-hoc pairwise t-test with Bonferroni correction were made with amino acid ratios for individuals. Overall, out of the 45 possible pairwise comparisons between all hair samples, 38 (84%) were differentiable. Out of the 36 possible pairwise comparisons between brown haired individuals, 32 (89%) were considered differentiable using univariate statistics. Multivariate statistics were also attempted but, overall, univariate models were sufficient for exclusionary purposes. These results indicate that amino acid ratio analysis can potentially be used as an exclusionary method using hair if DNA analysis cannot be performed, or to corroborate conclusions made following microscopic analysis.
