Alcohol‐Induced Osteopenia Among In‐Custody and Homicide Deaths from the Harris County Institute of Forensic Sciences

Four cases of in‐custody or unlawful death are presented as examples of increased bone fragility with an associated increase in fracture rates due to ethanol‐induced osteopenia. In addition, one of the individuals suffered fractures several weeks premortem, allowing some healing to take place. Using radiographs and physical examination, the ribs from these individuals are compared with those retained from three individuals with no history of alcoholism to illustrate diagnostic characteristics that will be notable using standard autopsy and anthropological procedures. Trabecular bone mass is notably decreased in the alcoholic group leading to a greater chance of fracture occurring during conflict, including arrest and in‐custody situations. The average number of perimortem fractures among the alcoholic individuals is 15, while the control group is six. In the case of the individual with healing, the degree of bone repair on the ribs was less than is expected considering the interval between injury and death.     

We mind and we care but have things changed? Assessment of progress in the reporting,investigating and prosecution of allegations of rape

Abstract

This paper discusses three themes in relation to assessing progress in the Criminal Justice System's (CJS) ability to investigate and successfully prosecute rape. The themes are business as usual, the justice gap and implementation problems. They arose as a consequence of two discussion papers in this volume by Kate Cook and Jan Jordan, who take positions of optimism and pessimism with respect to improvements for rape victim survivors after a series of reforms and changes in police and prosecution procedures. The stimulus for these papers was the latest review in England and Wales into the CJS's approach to rape conducted by Baroness Stern (2010). The present paper observes that the lack of systematic evaluative research makes it difficult to assess whether innovations in the CJS with respect to rape have been effective or to partial out the relative contribution law reform and changing police or prosecution practice may have made to reporting and conviction rates. Finally, it is suggested that intensification of effort to fully implement review recommendations may achieve limited improvement because of the characteristics of an adversarial legal model.     

Using Booking Data to Model Drug User Arrest Rates: A Preliminary to Estimating the Prevalence of Chronic Drug Use

Public policy is often concerned with the size and characteristics of special populations that are difficult to reach in household surveys. Chronic drug users, who often live outside conventional households, provide the illustration motivating this paper. An alternative to household surveys is to question chronic drug users where they congregate—jails, treatment programs, and shelters, for example. Using such opportunistic data for prevalence estimation raises difficult problems for statistical inference: Study subjects who arrive at the collection points cannot be deemed a random sample of the general population. However, if we could estimate the rates at which chronic drug users arrive at the collection points, then we could use those estimates to weight the sample to represent the population. This paper presents a modified Poisson mixture model used to estimate the stochastic process that accounts for how chronic drug users get arrested. It uses that model to estimate arrest rates for 38 counties using up to sixteen quarters of data from the Arrestee Drug Abuse Monitoring survey.

CONCENTRATED DISADVANTAGE,TRADITIONAL MALE ROLE MODELS,AND AFRICAN‐AMERICAN JUVENILE VIOLENCE*

In a stagnating urban economy, Elijah Anderson's (1999) Code of the Street depicts a disadvantaged environment where residents face high levels of joblessness, poverty, racial residential isolation, and family disruption. Anderson argues that the loss of job opportunities for African‐American men deprived younger generations of traditional male role models. That is, in a disadvantaged urban setting with a lack of male role models participating in legitimate labor market activity, many young people may turn to violence. Drawing on insights from Anderson's ethnographic work, we assess the generality of Anderson's claims more broadly and explore the potential connection between his work and the macrolevel research on urban violence. Specifically, we explore the influence of male role models (older, employed black males) and the concentration of urban disadvantage on black juvenile arrests for violence across multiple cities in 2000. Overall, we find empirical support for Anderson's concerns over the removal of traditional male role models from urban areas as a result of concentrated disadvantage. Specifically, we find that the presence of traditional male role models reduces the rates of African‐American youth violence. Additionally, our measure of traditional male role models mediates the relationship between structural disadvantage and juvenile violence. We discuss the contributions of Anderson's work to the macrolevel study of urban violence.     

The Relationship Between Crime and Stop,Question, and Frisk Rates in New York City Neighborhoods

The current study builds on prior research in an analysis of the relationship between monthly violent and property crime rates in New York City census tracks and the New York City Police Department’s highly contentious stop, question, and frisk (SQF) policy. We find that higher doses of SQF are associated with small crime reductions generally and specific crime reductions for stops of blacks, Hispanics, and whites. But the way the policy was implemented precludes strong causal conclusions. Now that a federal court has intervened and SQF is undergoing change, the court monitor, New York Police Department, and city officials should partner with researchers in experimental evaluations to determine the optimal mix and dosage of enforcement strategies that safeguard the rights and liberties of citizens while enhancing public safety.     

利率市场化对国民经济的影响及对策

利率市场化是经济市场化的必然要求。在商品价格绝大部分已经实现市场化的条件下,货币的资金价格———利率客观上也就有了市场化的需要。利率实现市场化,管制利率对市场均衡利率的偏离将逐步消除,从而可以自行化解由利率管制导致的货币市场与商品市场难以同时均衡的矛盾,解决“储蓄居高不下”或“投资饥渴症”等极端现象,有助于金融效率的提高,有利于新时期社会经济的良性发展。但是,利率市场化作为一种制度的变革,在其实施的过程中,必然给国民经济带来一定的负面影响,对此,我们应有充分的认识和准备。     

Unproductive Activities and the Rate of Surplus Value at the Industry Level in Korea, 1995–2015

ABSTRACT

In order to explain how the Korean economy underwent structural change through the two crises of 1997– 1998 and 2008 within the context of globalisation, this article focuses on class analysis and inter-sectoral value transfer by estimating the sectoral rates of exploitation along with the sectoral monetary expressions of labour time. Our data indicate the possibility that the expansion of unproductive activities, accompanied by intensification of exploitation within the unproductive sectors, might not have overtaken capital accumulation in Korea during 1995–2015. It can also be concluded that the condition for manufacturing’s capital accumulation steadily improved since the 1997–1998 crisis but started to deteriorate after 2011. Our value-theoretic analysis provides a foundation for understanding the context of the regime change, which may plausibly characterise the Korean economy in the last couple of decades.     

Novices cannot fill the examiners’ shoes: Evidence of footwear examiners’ expertise in shoe comparisons

The value of a footwear examiner’s opinion centres on their ability to determine whether a particular shoe made an impression with greater accuracy than a novice. However, there has been limited research on the expertise of footwear examiners and the accuracy and reproducibility of their decisions. In the current study, we measured the accuracy and consensus of 31 footwear examiners versus a comparison group of 29 novices. Participants completed 20 ground truth known mock shoe comparisons. Results demonstrated that footwear examiners were more accurate than novices, regardless of comparison difficulty. Overall, on trials where probative decisions were given, examiners made false identifications and false exclusions on a total of 3% and 2% of trials, while novices made false identifications and false exclusions on a total of 19% and 17% of trials. Examiners also demonstrated better consensus in their opinions than novices, although both groups demonstrated low levels of agreement in their responses and variability in their interpretation of the conclusion scale. In summary, these findings support the proposition that footwear examiners show expert-level performance in matching known and unknown footwear impressions. These performance estimates may help the criminal justice system to appropriately value footwear examination evidence.     

教育收益率的性别差异分析

很多研究均发现女性的教育收益率显著高于男性。本文利用中国城镇居民入户调查数据,也发现2004年中国城镇女性职工的教育收益率比男性高约2个百分点。进一步的分析表明,职工的教育水平与其面临的工资性别歧视程度呈反向关系,即低教育水平职工中的工资性别歧视程度更高,结果导致不同教育水平的女性之间的工资差异比男性更大,从而女性的教育收益率更高。
