Advocating Ideal Type Policy for Police Officer Wellness Based on Body Mass Index as a Predictor of Self-Reported Occupational Stress

Scholars have validated both the damaging presence of police officer stress and separately, their increasing obese condition in the United States. Previous studies of police officers focus on stress or body weight, but not these variables conjointly. The purpose of this study was to inform policy creation by examining the problem of officer stress in relation to the calculated body mass index (BMI) values and to gain insight into stress outcomes. Lazarus and Folkman\u27s stress-coping theory served as the research lens to examine if BMI would significantly contribute to the percent change of R2 variance accounted for in the predictive effect of self-reported organizational and operational stress in the past 6 months after controlling for age, gender, rank, marital status, shift work, and seniority. This quantitative research consisted of survey data that were collected from 132 volunteer officers using McCreary\u27s Police Stress Questionnaires. Multiple regression analysis tested the predictive relationship between BMI and stress and regression model outputs illustrated no statistically significant relationship between officer stress and BMI; however, post hoc analyses found shift work to be a significant stress predictor (p = .01). Based on regression results and this body of research, social change implications include police administrators promoting policies and training which protects officers from the harmful effects of stress and BMI. Lessened stress can have a positive influence on the police and the entire public they serve

Product Module Rig Test

The low emissions potential of a Rich-Quench-Lean (RQL) combustor for use in the High Speed Civil Transport (HSCT) application was evaluated as part of Work Breakdown Structure (WBS) 1.0.2.7 of the NASA Critical Propulsion Components (CPC) Program under Contract NAS3-27235. Combustion testing was conducted in cell 1E of the Jet Burner Test Stand at United Technologies Research Center. Specifically, a Rich-Quench-Lean combustor, utilizing reduced scale quench technology implemented in a quench vane concept in a product-like configuration (Product Module Rig), demonstrated the capability of achieving an emissions index of nitrogen oxides (NOx EI) of 8.5 gm/Kg fuel at the supersonic flight condition (relative to the program goal of 5 gm/Kg fuel). Developmental parametric testing of various quench vane configurations in the more fundamental flametube, Single Module Rig Configuration, demonstrated NOx EI as low as 5.2. All configurations in both the Product Module Rig configuration and the Single Module Rig configuration demonstrated exceptional efficiencies, greater than 99.95 percent, relative to the program goal of 99.9 percent efficiency at supersonic cruise conditions. Sensitivity of emissions to quench orifice design parameters were determined during the parametric quench vane test series in support of the design of the Product Module Rig configuration. For the rectangular quench orifices investigated, an aspect ratio (length/width) of approximately 2 was found to be near optimum. An optimum for orifice spacing was found to exist at approximately 0.167 inches, resulting in 24 orifices per side of a quench vane, for the 0.435 inch quench zone channel height investigated in the Single Module Rig. Smaller quench zone channel heights appeared to be beneficial in reducing emissions. Measurements were also obtained in the Single Module Rig configuration on the sensitivity of emissions to the critical combustor parameters of fuel/air ratio, pressure drop, and residence time. Minimal sensitivity was observed for all of these parameters

Green Supply Chain Management: A review of recent scientific production (2001-2012) Green Supply Chain Management: Uma análise da produção científica recente (2001-2012)

The goal of this study was to analyze international scientific production in the area of constant-production green supply chain management from 2001 to 2012 using the Business Source Complete database (EBSCO Host). The database was checked for cooperation between authors and institutions, author entrants, production and continuity categories, regularity of publication and distribution of publications over time. Ninety articles were included in the sample, and the results showed a reduction in the number of publishing authors, concentrated in one-timers category with 68.90. The highest yield for a single author was 10 articles, and the most prolific periodical was the Journal of Cleaner Production, with 12 articles published on the subject. Clark University (USA) stood out in terms of output, with 12 affiliated authors. It was concluded that the subject had experienced a significant rise in published literature over that time period
