Heel-ball (HB) index: sexual dimorphism of a new index from foot dimensions

The present research is aimed to introduce Heel-ball (HB) index from foot dimensions and determine whether this index exhibits sexual dimorphism. The study was conducted on a sample of 303 North Indian individuals (154 men, and 149 women) aged between 13 and 18 years. The stature, body weight, foot breadth at the ball (BBAL), and foot breadth at heel (BHEL) were measured. The HB index was derived by the formula BHEL × 100/BBAL. Although the mean HB index was larger in women in both feet it showed statistically significant sex differences in the right foot only. The study shows that while the foot dimensions show a positive correlation with stature and weight, the HB index is independent of the stature and weight of an individual. This novel index (HB index) may be utilized in sex determination when a part of the foot is brought for medico-legal investigation.     

安宫牛黄丸治疗重症手足口病31例

目的 观察安宫牛黄丸治疗重症手足口病的临床疗效,并初步探讨其作用机制。方法 将62例重症手足口病患儿随机分为对照组及观察组,每组各31例。对照组给予抗病毒、降颅压、丙种球蛋白等治疗,观察组在对照组基础上加用安宫牛黄丸治疗。治疗7 d后,比较两组临床疗效,观察两组患儿治疗前后血清神经细胞特异性烯醇化酶(neuron specific enolase,NSE)、S-100β以及肿瘤坏死因子-α（tumor necrosis factor α,TNF-α）、白细胞介素-6（interleukin 6,IL-6）水平的变化。结果 观察组临床疗效明显优于对照组（P＜0.05）。与对照组比较,观察组退热时间、皮疹消退时间及住院时间均明显缩短（P＜0.05）。治疗7 d后,两组患儿血清NSE、S-100β、TNF-α和IL-6水平较治疗前均明显下降(P＜0.05),观察组患儿治疗后血浆NSE、S-100β、TNF-α、IL-6降低值明显大于对照组（P＜0.05）。结论 在常规治疗基础上加用安宫牛黄丸能有效减轻重症手足口病患儿炎性反应,提高临床疗效。

THE PHILADELPHIA FOOT PATROL EXPERIMENT: A RANDOMIZED CONTROLLED TRIAL OF POLICE PATROL EFFECTIVENESS IN VIOLENT CRIME HOTSPOTS*

Originating with the Newark, NJ, foot patrol experiment, research has found police foot patrols improve community perception of the police and reduce fear of crime, but they are generally unable to reduce the incidence of crime. Previous tests of foot patrol have, however, suffered from statistical and measurement issues and have not fully explored the potential dynamics of deterrence within microspatial settings. In this article, we report on the efforts of more than 200 foot patrol officers during the summer of 2009 in Philadelphia. Geographic information systems (GIS) analysis was the basis for a randomized controlled trial of police effectiveness across 60 violent crime hotspots. The results identified a significant reduction in the level of treatment area violent crime after 12 weeks. A linear regression model with separate slopes fitted for treatment and control groups clarified the relationship even more. Even after accounting for natural regression to the mean, target areas in the top 40 percent on pretreatment violent crime counts had significantly less violent crime during the operational period. Target areas outperformed the control sites by 23 percent, resulting in a total net effect (once displacement was considered) of 53 violent crimes prevented. The results suggest that targeted foot patrols in violent crime hotspots can significantly reduce violent crime levels as long as a threshold level of violence exists initially. The findings contribute to a growing body of evidence on the contribution of hotspots and place‐based policing to the reduction of crime, and especially violent crime, which is a significant public health threat in the United States. We suggest that intensive foot patrol efforts in violent hotspots may achieve deterrence at a microspatial level, primarily by increasing the certainty of disruption, apprehension, and arrest. The theoretical and practical implications for violence reduction are discussed.     

Sex estimation from foot dimensions in an indigenous Indian population

Dismembered/severed human remains are frequently found in cases of mass disasters and criminal mutilation. Sex estimation from foot dimensions, therefore, has a vital role in establishing personal identity. There is a paucity of literature on this issue from various Indian populations. The "Rajbanshi" is one such indigenous population located in the state of West Bengal, India. The present study attempts to estimate sex from foot length, foot breadth, and foot index among 350 living adult Rajbanshi (175 men and 175 women) individuals (age range: 18-50 years). The study concludes that foot dimensions show significant sex differences. Both sectioning point and regression analyses can be used to estimate sex from foot dimensions. However, multiple regression models appear to have the maximum accuracy in sex differentiation. Although statistically significant sex differences are evident for foot index, its practical utility appears to be limited because of considerable overlap.
