Efforts at improving earthquake recovery policies have been hampered by a lack of criteria and standards for evaluating and repairing damaged buildings. The Applied Technology Council has developed a performance-based methodology for the evaluation of earthquake-damaged concrete wall buildings and masonry wall buildings, recently published as FEMA 306/307/308. The methodology provides a way to quantify damage in terms of loss of seismic performance capability. It also provides guidelines for remedial measures to restore or improve seismic performance capability. In this methodology, the expected future seismic performance of a building is evaluated in its pre-event, damaged, and repaired conditions. Following the nonlinear static analysis procedure, displacement demands and capacities of the structure are used as indices of seismic performance. Identifying the governing mechanism of nonlinear deformation and the behavior mode of a structure and its components is shown to be a necessary first step towards evaluating expected seismic performance, interpreting indications of damage, and assessing their significance. The methodology provides a technical resource for understanding how buildings respond seismically on both global and component levels, and gives a basis for formulating post-earthquake policies.
PurposeThe purpose of this study is to examine the association between components of metabolic syndrome with health-related fitness (HRF) and perceived stress in a sample of law enforcement officers.Design/methodology/approachLaw enforcement officers (N = 28) from the Mountain West region of the US reported their HRF scores (1.5 mile run, push-up, and sit-ups), had their blood drawn (glucose, triglycerides, high-density lipoprotein (HDL)) and had their waist circumference and blood pressure measured in a fasted state. Officers also completed a short questionnaire to assess health-enhancing physical activity (SQUASH) and both the Organizational and Operational Police Stress Questionnaires (PSQ-Org, PSQ-Op).FindingsLinear regression models revealed a positive linear relationship between glucose levels and 1.5 mile run times (beta = 0.560, p = 0.021, R2 = 0.24). A bivariate positive linear relationship between waist circumference and 1.5 mile run times was found to be significant (R2 = 0.17, p = 0.041). For every minute increase in 1.5-mile run times, PSQ-Org scores significantly increased by 0.543 standard deviations (p = 0.022) with 25% of the variance explained (R2 = 0.25). There were no statistically significant parameter estimates from the logistic regression equations when dependent variables were treated on the categorical measurement scale using recommended cut-points.Research limitations/implicationsIn conclusion, those who performed better on the 1.5 mile run were more likely to have lower fasting glucose levels, experience less stress and have a smaller waist circumference.Practical implicationsTherefore, according to these findings, it is imperative for those in law enforcement to improve their cardiorespiratory endurance to minimize stress and reduce their risk of metabolic syndrome.Originality/valueThis research is novel according to a recent PubMed search using the keywords “law enforcement,” “Metabolic Syndrome” and “fitness testing.”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
