Secondary transfer of organic gunshot residues: Empirical data to assist the evaluation of three scenarios

The present study aimed at providing data to assess the secondary transfer of organic gunshot residues (OGSR). Three scenarios were evaluated in controlled conditions, namely displacing a firearm from point A to point B, a simple handshake and an arrest involving handcuffing on the ground. Specimens were collected from the firearm, the hands of the shooter and the non-shooter undergoing the secondary transfer in order to compare the amounts detected.Secondary transfer was observed for the three scenarios, but to a different extent. It was found that displacing a firearm resulted in secondary transfer in <50% of the experiments. The firearm also had an influence, as contrary to the pistol, no secondary OGSR were detected using the revolver. Shaking the hand of the shooter also transferred OGSR to the non-shooter's hand. In that case, the amount of OGSR was generally higher on the shooter than on the non-shooter. Finally, the largest secondary transfer was observed after the arrest with handcuffing with positive results in all cases using the pistol. In that scenario, the amounts on the shooter and the non-shooter were in the same range.This study highlights that the secondary transfer must be taken into account in the interpretation of OGSR. Indeed, an individual's hands might be contaminated by handling a firearm or having physical contact with a shooter.     

A Statistical Validation of the Individuality and Repeatability of Striated Tool Marks: Screwdrivers and Tongue and Groove Pliers*

Abstract: Tool mark identification relies on the premise that microscopic imperfections on a tool’s working surface are sufficiently unique and faithfully transferred to enable a one‐to‐one association between a tool and the tool marks it creates. This paper presents a study undertaken to assess the validity of this premise. As part of this study sets of striated tool marks were created under different conditions and on different media. The topography of these tool marks was acquired and the degree of similarity between them was quantified using well‐defined metrics. An analysis of the resulting matching and nonmatching similarity distributions shows nearly error‐free identification under most conditions. These results provide substantial support for the validity of the premise of tool mark identification. Because the approach taken in this study relies on a quantifiable similarity metric, the results have greater repeatability and objectivity than those obtained using less precise measures of similarity.     

Isolation and characterisation of a novel sildenafil analogue adulterant,desmethylpiperazinyl propoxysildenafil,in a dietary supplement

A new sildenafil analogue was detected during routine screening of dietary supplements suspected to be adulterated with an erectile dysfunction drug(s) using HPLC-DAD. The UV spectrum of this compound was highly similar to that of sildenafil and almost identical to that of desmethylpiperazinyl sildenafil. The analogue was purified by using semi-preparative HPLC and structurally elucidated by performing mass spectrometric and NMR spectroscopic experiments. The spectral data revealed that this sildenafil analogue bears an n-propoxy group instead of an ethoxy group and possesses no methylpiperazinyl moiety. The isolated compound, structure of which was further confirmed by spectral comparison with synthetic one, was thus named as desmethylpiperazinyl propoxysildenafil.     

Socialisation to interdisciplinary legal education: an empirical assessment

This article provides novel empirical survey evidence on socialisation factors leading lecturers to implement interdisciplinary teaching in law. Recent debates on legal scholarship and higher education legal institutions advocate the introduction of interdisciplinary approaches to legal studies. Nevertheless, there is still little evidence of how this lecturing philosophy might be affected by socialisation with other disciplines. To address this, we analyse the case of external lecturers in the Faculty of Law at the University of Copenhagen in Denmark, who constitute the majority of the teaching staff in this institution. To explain the adoption of interdisciplinary teaching, we rely on socialisation factors connected to their former higher education and socialisation in research and multidisciplinary environments.     

Patterns of victim marginalization in victim-offender mediation: some lessons learned

This article discusses issues that restorative justice programs may face during implementation and lessons learned from an exploratory study. We examined various perspectives of multiple participants who experienced a Victim-Offender Mediation (VOM) program in a mid-sized Midwestern city in the U.S. The primary data source comprised 34 interviews with 37 participants including adult crime victims, juvenile offenders and their parents, mediators, and representatives from referring agencies. Observations complemented the interview data. Findings revealed patterns of victim marginalization during the processes used: victims were not prepared appropriately; were at times pressured by mediators to behave in certain ways; and, occasionally felt intimidated by offenders and/or their families. We discuss some factors that may have influenced the emergence of these patterns. This study revealed gaps between the guiding principles of restorative justice theory and field practices, particularly sensitivity toward victims to meet their needs. We suggest that restorative justice programs should consider using a monitoring system to ensure that the processes used remain consistent with the values and principles of restorative justice.     

What do students really know about criminal justice?

This survey of three hundred and twenty undergraduate students attempted to determine their knowledge of crime and punishment in North Carolina. Respondents answered a series of open- and closed-ended questions regarding various legal topics, such as statutory rape and the legal ages for tobacco and alcohol use. The participants were also asked to list punishments for various offenses, such as possession of marijuana, driving while intoxicated, and rape. They were then asked to define certain legal terms such as larceny. The results indicated that most students were unable to provide correct corresponding punishments for many offenses. They were also unable to accurately define various legal terms, such as robbery or rape. The implications for stronger education in the area of criminal justice are discussed.     

Collaborative Behavior and the Performance of Government Agencies

ABSTRACT

While collaboration among individuals, work groups, and organizations is central for understanding the performance of public agencies, most studies have focused on collaboration between organizations or sectors. We develop a model that focuses on two types of collaborative behavior: between persons (both horizontal and vertical) and between work units. We empirically test our hypotheses using data on work collaboration and perceptions of public agency performance from the United States federal government. We introduce a method for estimating the impact of different types of collaborative behavior that also accounts for nonlinear effects and a dependent variable that takes ordered values. We find that intra-organizational collaborative behavior has a large impact on organizational performance and that horizontal collaborative behavior between workers has the greatest impact among the specific types.     

David Marr's ‘Vietnamese anticolonialism’

Abstract

Because of its legendary resistance against the United States and its struggle for national salvation, Vietnam has entered into the consciousness of progressive mankind and has begun to attract the attention of foreign historians. In the United States, the war of aggression waged by the U.S. government has been costly in lives and property and has seriously weakened the country in all aspects, leading to the increasing opposition among the American people to the war. While protesting against the policy of the U.S. government of continuing and widening its aggression in Vietnam, for the purpose of defending America's honor and to fight for their democratic rights and economic livelihood, the American people from all walks of life have been building a friendly relationship with the Vietnamese people. Because of this reason, the American people would like to have a better understanding of the land and people of Vietnam, past and present. However, in the United States “the study of Vietnamese anti-colonial movements has been largely the preserve of the political scientist, the practicing journalist, and the intelligence specialist.” Since nearly all of these people have conducted their research according to strict political guidelines from the White House and the Pentagon, they have ignored the historical truth in an effort to justify present-day American neo-colonialism. Despite these limitations, Marr's Vietnamese Anticolonialism is one of the first historical studies published in the United States which makes a larger contribution to America's understanding of the Vietnamese struggle for freedom and independence, and thereby shows that the present U.S. war of aggression is doomed to failure.     

Socialist development: The political economy of agrarian reform in Vietnam

Abstract

Since reunification in 1976, Vietnam's faltering economy has produced a crisis of grave proportions, the causes of which are not yet fully understood. The drawn-out consequences of 45 years of war and international isolation are obviously important elements affecting the Vietnamese economy, but the crisis has continued—if not worsened since the end of the war. Grain production—16.2 million tons in 1983—has not kept pace with consumption needs. Official figures indicate that during 1983 per capita food production was 296 kg., up from a 1978 low of 243 kg., but still well below war-time levels.     

Television and attitudes toward foreign countries: A report on a survey of Scandinavian children

Children of all ages are more likely to use electronic sources of information such as television and radio-than they are print sources-such as newspapers and magazines-according to a variety of studies. This study examines whether this tendency continues if the children are forced by their primary and secondary school teachers to use multiple news sources-of their own choice-to follow an election campaign. Based on responses from an extraordinarily large sample of 24,348 children, this study focuses on media use by participants in the Kids Voting USA civics education program. Study results demonstrate that even when seeking campaign information in 1994, a non-presidential election year when the emphasis was more on state and local races, children overwhelmingly preferred television and radio as sources of information. Newspaper usage trailed both electronic forms even when a child's family subscribed to a paper. The study found no significant difference between White and non-White children in their choices and uses of information sources. The large sample size also allowed for a detailed look at often neglected subgroups such as Native American children (n = 1,114) and Asian-American children (n = 768).
