Forensic veterinary radiology: ballistic-radiological 3D computertomographic reconstruction of an illegal lynx shooting in Switzerland

The most popular handgun in Brazil is the single round-barrel caliber 0.38 revolver. In recent years, however, owing to the modernization of police arms and their availability on the legal and illicit markets, pistols have become increasingly popular and currently represent about 20% of police seizures. In a previous paper we presented a novel collection method for gunshot residues (GSR) using a sampling procedure based on ethylenediamine-tetraacetic acid (EDTA) solution as a complexing agent on moistened swabs with subsequent detection using sector field-high resolution-inductively coupled plasma-mass spectrometry (SF-HR-ICP-MS). In the present paper, we discuss the capability of this methodology to identify antimony (Sb), barium (Ba) and lead (Pb) on the hands of volunteers after shot tests with 9 mm and 0.40 in. caliber pistols. Two types of munitions were tested: 9 mm Taurus and clean range. The use of a technique with high sensitivity, such as SF-HR-ICP-MS, permits the identification of low concentrations (less than 1 microg/L) of metals in firearm residue and constitutes a powerful tool in forensic science. We also discuss the importance of the sampling procedure, including collection from a different body part than the gun hand of the suspect. Comparison of the analytical data obtained allows clear discrimination between samples from the hands of shooters and non-shooters.     

The Limits of Theoretical Integration

The integration of theoretical knowledge is often seen as the ultimate goal of research activity in the social sciences. In this article I explore limits in the form and degree to which our knowledge can be integrated, as well as limits in the worth and desirability of some kinds of integration. Most of the analysis depends on drawing two kinds of distinctions in theoretical activity—between theoretical and metatheoretical work and among different types of integration in each kind of work. Using primarily examples from theory and research on justice issues, I articulate three different ways in which work at the theoretical level can be integrated. Each type represents a distinct kind of knowledge development, requires different criteria of evaluation, and involves a varying degree of difficulty to achieve. Nevertheless, each of these types of integration is well worth pursuing. Justice research shows evidence of work involving all three types. Using a somewhat broader range of examples, I also distinguish three different ways in which metatheoretical work might be integrated. Again, each type is quite distinct and should be evaluated in different ways. However, each of these types is significantly more difficult to achieve than any of the types of theoretical integration. Moreover, I suggest that the last metatheoretical type—involving the integration of entire strategies, perspectives or schools of thought—is probably not even a desirable goal. As a consequence of these analyses, I recommend (1) that social scientists in general (and justice researchers in particular) focus most of our attention on one or another of the types of theoretical integration, and (2) that we articulate clearly which type of integration we are pursuing and evaluate our success at the effort using only the appropriate criteria. An earlier version of this paper was presented at the Social Justice Conference in Bremen, Germany, 10–12 March 2005.

Impact of deception detection errors on public's trust in the police

Purpose. The present study explored the public's attitude towards errors in police officers’ detection of deception. Based on findings on trust in the police after responses to terrorist threats, we predicted a positive influence of a correct credibility assessment and of a risk‐averse response bias of police officers on public's trust. Methods. A general population sample (N= 151) read a hypothetical scenario concerning a credibility judgment and indicated their trust in the officers making the judgment. Decision outcome was manipulated by varying the four outcomes of a signal‐detection task, namely, Hit, Miss, False Alarm, and Correct Rejection. Results. In line with findings on trust in the police following responses to terrorist threats, people trusted police officers more if they judged the credibility of a suspect correctly. Moreover, officers who disbelieved the suspect's statement were trusted more than officers who believed, independently of outcome correctness. Furthermore, this effect was moderated by individual differences in error weighting. Conclusions. In sum, these findings indicate that lie‐biased credibility judgments made by police officers are supported by the public and increase their trust in the police. In addition, the present findings suggest that an asymmetrical weighting of judgment errors is a relevant factor in explaining the development of and attitude towards lie bias.     

The New Chum girl: Upending Colonial Clichés in Lilian Turner's Emigration Novel

This essay analyses Lilian Turner's Three New Chum Girls (1910) to show how settler authors played with colonial clichés as part of a critical reaction to shifting imperialist and nationalist ideologies at the turn of the century. In particular, Turner redefines the derogatory colonial term “new chum”—commonly used to describe a recent emigrant in the settler colonies—to suggest what the welcome of new arrivals ought to be like. Yet if her deliberate reworking of stereotypes consequently contains an element of wish-fulfilment, the narrative also offers a startlingly stark portrayal of settler life. Emigration, Turner contends in the novel, is neither easy nor a solution to problems at home. Nor does settler Australia provide a convenient space for fortune-seeking sojourns. Turner thus dismantles two clusters of common clichés: emigration as a pat ending in fiction and settlers' return to the homeland as an equally expedient plot twist. The self-irony that runs through much of her intertextual rewriting of both metropolitan fiction and male-coded settler writing reveals how emigration and return were being imagined and written about differently in the settler colonies and how Turner was utilising the exposure of false expectations to promote her vision of a welcoming settler community.
