The impact of stress on cognitive components of child abuse potential

The purpose of the present research was to test the effects of situational stress on the components of the cognitive behavioral model, including expectations, interpretations, and behavioral responses to child behaviors (Twentyman et al., 1985). It was predicted that parental abuse potential would be positively related to inappropriate expectations, to negative and internally caused interpretations of child behavior, and to negative parental responses. Second, it was expected that interpretations and responses would be more negative as child abuse potential increased. Sixteen mothers from a child abuse prevention and treatment program completed the Child Abuse Potential Inventory (Milner and Wimberly, 1980) and provided interpretations, evaluations, and responses to a set of vignettes depicting normal child behaviors. The data supported the hypotheses. As abuse potential increased, parent responses were judged as more controlling, punishing, rejecting, and aroused. High stress strengthened the magnitude of these responses. These findings were interpreted within the context of a cognitive behavioral model.     

Quantitative analysis of multiple illicit drugs in preserved oral fluid by solid-phase extraction and liquid chromatography-tandem mass spectrometry

We present a validated method for the simultaneous analysis of basic drugs which comprises a sample clean-up step, using mixed-mode solid-phase extraction (SPE), followed by LC-MS/MS analysis. Deuterated analogues for all of the analytes of interest were used for quantitation. The applied HPLC gradient ensured the elution of all the drugs examined within 14 min and produced chromatographic peaks of acceptable symmetry. Selectivity of the method was achieved by a combination of retention time, and two precursor-product ion transitions for the non-deuterated analogues. Oral fluid was collected with the Intercept, a FDA approved sampling device that is used on a large scale in the US for workplace drug testing. However, this collection system contains some ingredients (stabilizers and preservatives) that can cause substantial interferences, e.g. ion suppression or enhancement during LC-MS/MS analysis, in the absence of suitable sample pre-treatment. The use of the SPE was demonstrated to be highly effective and led to significant decreases in the interferences. Extraction was found to be both reproducible and efficient with recoveries >76% for all of the analytes. Furthermore, the processed samples were demonstrated to be stable for 48 h, except for cocaine and benzoylecgonine, where a slight negative trend was observed, but did not compromise the quantitation. In all cases the method was linear over the range investigated (2-200 microg/L) with an excellent intra-assay and inter-assay precision (coefficients of variation <10% in most cases) for QC samples spiked at a concentration of 4, 12 and 100 microg/L. Limits of quantitation were estimated to be at 2 microg/L with limits of detection ranging from 0.2 to 0.5 microg/L, which meets the requirements of SAMHSA for oral fluid testing in the workplace. The method was subsequently applied to the analysis of Intercept samples collected at the roadside by the police, and to determine MDMA and MDA levels in oral fluid samples from a controlled study.     

Criminal history and assaults on intimate partners by Mexican American and non-Mexican White college students

This study analyzed a sample of 348 college students to examine the role that criminal history and Mexican ethnicity play in predicting intimate partner violence. Respondents who committed crimes in the past (before the age of 15) had a higher probability of severely physically assaulting a partner than those respondents who had committed crime later in life (after the age of 15). A history of property crime was found to be a better predictor of severe partner assault than a history of violent crime. The results support a generalist perspective on crime, which states that most individuals typically do not commit one type of crime solely but commit a variety of different crimes (property and violent). This study also found differences between Mexican American and non-Mexican White students in reference to minor assaults on a partner.     

Cracked Ceilings, Firmer Floors, and Weakening Walls: Trends and Patterns in Gender Representation among Executives Leading American State Agencies, 1970–2000

Trends of female access to and presence in responsible governmental positions have gained substantial attention. The research reported here assesses and seeks convergence on several issues associated with gender representation. It extends the research by focusing on top executive posts in American state governments. In particular, the presence of women agency heads in all 50 states is examined from 1970 through 2000 using the lenses of passive representativeness and active representation. The authors find, first, that women face fewer blockages in securing top posts—the glass ceilings are cracking. Second, women's access to peak executive positions springs from more solid educational, career, and organizational foundations or "floors." Third, lateral career movements are penetrating the "walls" surrounding traditionally male-dominated agency types. The essay concludes with a framework for understanding relationships involving passive representativeness, active representation, and representative results. That framework assists in shifting attention toward the consequences of both passive and active representation.
