The Prevalence of Female Representation in Supervisory and Management Positions in American Law Enforcement: An Examination of Organizational Correlates

Increasing gender diversity in American policing has long been a focus of reform efforts since the 1960s. Although the proportion of women in the profession improved initially and research has focused on the gender breakdown of police organizations in general, less scholarly and empirical attention has been directed to female representation in positions of power (i.e., supervisory and management roles). Using data from the 2013 Law Enforcement Management and Administrative Statistics survey, the current study examined the prevalence as well as the organizational correlates of female representation in supervisory (e.g., sergeants), mid-level management (e.g., lieutenants) and chief executive roles in departments across the United States. The findings indicate a number of factors associated with female representation in supervisory and mid-level management positions, including the size and type of agencies, geographic region of the country, and potential indicators of professionalism. Policy implications and directions for future research are discussed.     

Bioinformatics Approach to Assess the Biogeographical Patterns of Soil Communities: The Utility for Soil Provenance,

Soil DNA profiling has potential as a forensic tool to establish a link between soil collected at a crime scene and soil recovered from a suspect. However, a quantitative measure is needed to investigate the spatial/temporal variability across multiple scales prior to their application in forensic science. In this study, soil DNA profiles across Miami‐Dade, FL, were generated using length heterogeneity PCR to target four taxa. The objectives of this study were to (i) assess the biogeographical patterns of soils to determine whether soil biota is spatially correlated with geographic location and (ii) evaluate five machine learning algorithms for their predictive ability to recognize biotic patterns which could accurately classify soils at different spatial scales regardless of seasonal collection. Results demonstrate that soil communities have unique patterns and are spatially autocorrelated. Bioinformatic algorithms could accurately classify soils across all scales with Random Forest significantly outperforming all other algorithms regardless of spatial level.     

Childhood Abuse,Intrapersonal Strength,and Suicide Resilience in African American Females who Attempted Suicide

There is a significant association between childhood abuse and suicidal behavior in low-income African American women with a recent suicide attempt. Increasingly, empirical focus is shifting toward including suicide resilience, which mitigates against suicidal behavior. This cross-sectional study examines childhood abuse, intrapersonal strengths, and suicide resilience in 121 African American women, average age of 36.07 years (SD?=?11.03) with recent exposure to intimate partner violence and a suicide attempt. To address the hypothesis that childhood abuse will be negatively related to suicide resilience and that this effect will be mediated by intrapersonal strengths that serve as protective factors, structural equation modeling examined the relations among three latent variables: childhood abuse (measured via physical, sexual, and emotional abuse), intrapersonal strengths (assessed by self-efficacy and spiritual well-being), and suicide resilience (operationalized via the three components of suicide resilience—internal protective, external protective, and emotional stability). The initial measurement model and the structural model both indicated excellent fit. Results indicated that childhood abuse was negatively associated with intrapersonal strengths and suicide resilience, intrapersonal strengths were positively associated with suicide resilience, and intrapersonal strengths fully mediated the association between childhood abuse and suicide resilience. Thus, the results suggest a positive and protective influence of intrapersonal strengths on suicide resilience in the face of childhood abuse in suicidal African American women. The clinical implications and directions for future research that emerge from these findings are discussed.     

Higher Capillary Electrophoresis Injection Settings as an Efficient Approach to Increase the Sensitivity of STR Typing

Abstract:  Evidentiary traces may contain low quantities of DNA, and regularly incomplete short tandem repeat (STR) profiles are obtained. In this study, higher capillary electrophoresis injection settings were used to efficiently improve incomplete STR profiles generated from low-level DNA samples under standard polymerase chain reaction (PCR) conditions. The method involves capillary electrophoresis with higher injection voltage and extended injection time. STR peak heights increased six-fold. Inherent to the analysis of low-level DNA samples, we observed stochastic amplification artifacts, mainly in the form of allele dropout and heterozygous peak imbalance. Increased stutter ratios and allele drop-in were rarely seen. Upon STR typing of 10:1 admixed samples, the profile of the major component did not become overloaded when using higher injection settings as was observed upon elevated cycling. Thereby an improved profile of the minor component was obtained. For low-level DNA casework samples, we adhere to independent replication of the PCR amplification and boosted capillary electrophoresis.

Les pratiques de fonctionnaires canadiens et québécois au chapitre des innovations du travail

This research focuses on the evolution and transformation of work organization and labour relations in the public service in Quebec and Canada. It seeks to determine the nature of innovations in the workplace and the level of employee participation in the innovation process. A survey of 2308 employees in six departments and agencies of the public service in Quebec and Canada reveals that the autonomy of employees, participation and shared responsibility for the development of innovations reflect an important transformation of the workplace. The effect of these innovations depends on the departments in which they occurred. However, the survey results do not permit an analysis of the scope of transformation of the organizational structure. Finally, this article shows that employees and managers are key players in the innovation process.
