Forensic Identification of Blood in the Presence of Contaminations Using Raman Microspectroscopy Coupled with Advanced Statistics: Effect of Sand,Dust, and Soil

Body fluid traces recovered at crime scenes are among the most common and important types of forensic evidence. However, the ability to characterize a biological stain at a crime scene nondestructively has not yet been demonstrated. Here, we expand the Raman spectroscopic approach for the identification of dry traces of pure body fluids to address the problem of heterogeneous contamination, which can impair the performance of conventional methods. The concept of multidimensional Raman signatures was utilized for the identification of blood in dry traces contaminated with sand, dust, and soil. Multiple Raman spectra were acquired from the samples via automatic scanning, and the contribution of blood was evaluated through the fitting quality using spectroscopic signature components. The spatial mapping technique allowed for detection of “hot spots” dominated by blood contribution. The proposed method has great potential for blood identification in highly contaminated samples.     

New ‘Mass Line’ Campaign

The Communist Party of China(CPC)recently began a new training campaign for Party members and cadres as part of a multi-pronged approach designed to confront a number of challenges facing China today.The purpose of the campaign is to reassert and deepen the Party’s values and connection with the Chinese masses,and to establish in the clearest of terms the professional and ethical requirements of service.     

Police and Alcohol Use: A Descriptive Analysis and Associations with Stress Outcomes

Alcohol misuse is a significant problem in police work. This study describes alcohol use correlates and examines psychological outcomes of stress associated with the use and level of alcohol by police officers. Measures: (1) AUDIT-Alcohol Use Disorders Identification Test; (2) demographics; (3) Center for Epidemiological Studies Depression scale; (4) Impact of Events Scale (PTSD); and (5) life events scale. The mean AUDIT score was M = 5.64 (low risk <8). Male officers had significantly higher scores in overall AUDIT total, hazardous alcohol use domain, and dependent symptoms domain (p = 0.004, 0.002, 0.031, respectively). Women officers in the hazardous drinking range on the AUDIT were significantly younger than women officers in the lower AUDIT range (p = 0.050). Males in the hazardous drinking range had significantly higher external life event scores than females (p = 0.037), suggesting a need for increased attention to the spillover effect of police work.     

Sub-Saharan African randomised clinical trials into male circumcision and HIV transmission: methodological, ethical and legal concerns

In 2007, WHO/UNAIDS recommended male circumcision as an HIV-preventive measure based on three sub-Saharan African randomised clinical trials (RCTs) into female-to-male sexual transmission. A related RCT investigated male-to-female transmission. However, the trials were compromised by inadequate equipoise; selection bias; inadequate blinding; problematic randomisation; trials stopped early with exaggerated treatment effects; and not investigating non-sexual transmission. Several questions remain unanswered. Why were the trials carried out in countries where more intact men were HIV-positive than in those where more circumcised men were HIV-positive? Why were men sampled from specific ethnic subgroups? Why were so many participants lost to follow-up? Why did men in the male circumcision groups receive additional counselling on safe sex practices? While the absolute reduction in HIV transmission associated with male circumcision across the three female-to-male trials was only about 1.3%, relative reduction was reported as 60%, but, after correction for lead-time bias, averaged 49%. In the Kenyan trial, male circumcision appears to have been associated with four new incident infections. In the Ugandan male-to-female trial, there appears to have been a 61% relative increase in HIV infection among female partners of HIV-positive circumcised men. Since male circumcision diverts resources from known preventive measures and increases risk-taking behaviours, any long-term benefit in reducing HIV transmission remains uncertain.     

Youth alcohol use and dating abuse victimization and perpetration: a test of the relationships at the daily level in a sample of pediatric emergency department patients who use alcohol

Objective: This study retrospectively examined the daily-level associations between youth alcohol use and dating abuse (DA) victimization and perpetration for a 6-month period. Method: Timeline Followback (TLFB) interview data were collected from 397 urban emergency department patients, ages 17 to 21 years. Patients were eligible if they reported past month alcohol use and past year dating. Generalized estimating equation (GEE) analyses estimated the likelihood of DA on a given day as a function of alcohol use or heavy use (≥4 drinks per day for women, ≥5 drinks per day for men), as compared with nonuse. Results: Approximately 52% of men and 61% of women participants reported experiencing DA victimization ≥1 times during the past 6 months, and 45% of men and 55% of women reported perpetrating DA ≥1 times. For both men and women, DA perpetration was more likely on a drinking day as opposed to a nondrinking day (ORs = 1.70 and ORs = 1.69, respectively). DA victimization was also more likely on a drinking day as opposed to a nondrinking day for both men and women (ORs = 1.23 and ORs = 1.34, respectively). DA perpetration and DA victimization were both more likely on heavy drinking days as opposed to nondrinking days (2.04 and 2.03 for men's and women's perpetration, respectively, and 1.41 and 1.43 for men's and women's victimization, respectively). Conclusions: This study found that alcohol use was associated with increased risk for same day DA perpetration and victimization, for both male and female youth. We conclude that for youth who use alcohol, alcohol use is a potential risk factor for DA victimization and perpetration.     

The State in World History: Perspectives and Problems

This paper investigates the role of the state in world history and analyses some of the major issues confronting such an investigation with a particular focus on the relationship between the modern European state and the other historical forms of the state. Firstly it considers the problems raised by the fact that the terminology of state analysis is derived from a discourse that arose to explain the particularity of European state development. Secondly it considers the problem of the origins of the state. It examines two major issues: van Creveld's argument that only modern European states are real states and the chiefdom/state distinction. It argues that new political forms occurred both with the emergence of civilisation and the "state" in the ancient world and with the development of the modern European state after 1300. Thirdly it considers the issue of a typology of states through an examination of the model developed by Finer in his The History of Government . It argues that this model is only really effective in dealing with pre–modern political forms and that the modern European state needs to be understood as a deviant from the Eurasian norm of the agrarian empire.     

The impact of rational participation models on voting attitudes

Rational models generally predict that only a few people should vote in most elections. A major reason why turnout is so high today is because of the numerous positive messages which citizens are routinely given about the value of their vote. A month after discussion of a model of rational participation, individuals were found to be more negative toward the institution of elections. A major reason for voting continued to be the feeling of duty to participate; subjects who felt no moral obligation would not go to the polls even if they were very interested in an election.     

On the reputation of state supreme courts

A state supreme court, in making and justifying choices, uses a variety of sources of information and authority—its own precedents, scholarly commentaries, articles in law reviews, encyclopedias, restatements, and so forth. Quite often a state supreme court appeals to the wisdom or rejects the lack of it in the decision of a sister court in order to arrive at or buttress reasoning in a particularly problematic case. These citations—construed as derogation or deference—yield very handy and nonreactive indicators of hierarchies of prestige between and among the highest appellate courts of the several states. In this paper, I develop a simple and general measure of judicial reputation, present evidence on the hierarchy of state supreme courts as of 1975, show how this ranking has changed in the last 50 years, and examine competing and sometimes complementary explanations of judicial prestige. Taken together, social diversity, judicial professionalism, political ideology, and the size of case load provide an impressive explanation of the reputation of state supreme courts.     

Spatial analysis of crime and region in the united states

The regionality of crime has been presented, debated, and questioned for over a centruy of this Nation’s history, usually involving a segmental approach to crime rates or treating the various crime rates separate from one another. This paper, using states as a real unit of analysis, develops two general crime dimensions using discriminant function analysis. These two dimensions, based upon complete estimation, demonstrate the discriminating power of crime profiles in assessing regionality. Also, region as an independent variable is shown to possess strong explanatory power regarding crime patterns. Although crime viewed at the state and regional level is highly generalized, it does draw attention to spatial and temporal consistencies in the general crime pattern. This level of analysis and this paper allows a greater understanding about the country and integrates available information on crime variations within our society. Finally, implications of this study for the current criminal justice system in the united States are discussed.
