Separation of visibly-excited fluorescent components in fingerprint residue by thin-layer chromatography

The use of lasers for the detection of fingermarks is widespread in the forensic field. Despite this, and the fact that many studies have been conducted into the composition of fingermark residue, the components responsible for the inherent visible fluorescence remain unidentified. Traditionally compositional studies have been performed on sweat, sebum, or skin surface washes, none of which are truly representative of the situation when a fingerprint is deposited on a surface. In this paper thin-layer chromatography (TLC) has been performed on sebum-rich fingermarks laid directly onto TLC plates and an argon ion laser used to visualize the separated components. It has been found to be a robust and reproducible method for studying the fluorescent components in fingermark residue and is considered to be more realistic than other methods of sample preparation as it eliminates the chances of extraneous matter being extracted from the skin surface. Investigations into the nature of the separated compounds have also been made and the results are reported.     

MI 6's Requirements Directorate: Integrating Intelligence into the Machinery of British Central Government

The following article examines the relationship between the British Secret Intelli-gence Service (SIS, a.k.a. MI 6) and the machinery of central government, particularly departments of state and other agencies which employ information generated by the SIS. It is argued the main link between the SIS and its consumers in British government is the SIS's requirements 'side', embodied throughout most of the post-war era in the form of a Requirements Directorate. The article argues that the Requirements mechanism operates as a line of communication between the SIS and its consumers separate from the Cabinet Office Joint Intelligence Organisation (JIO), although there is overlap and interdependency between the two architectures. This discussion traces the development of the 'requirements side' from the interwar period up to the post-Cold War era using information from archival sources and a programme of interviews with former UK intelligence officials. It is further argued that the structure and process of the SIS 'requirements side' has developed and changed as a consequence of changes in the structure of demand in the machinery of British government, including adapting to the increasingly central role of the JIO. However, despite that increasingly central role of the JIO, the 'requirements side' has continued to serve as the first point of contact between the SIS and its customers in Whitehall.

Predictive Crime Mapping: Arbitrary Grids or Street Networks?

Objectives

Decades of empirical research demonstrate that crime is concentrated at a range of spatial scales, including street segments. Further, the degree of clustering at particular geographic units remains noticeably stable and consistent; a finding that Weisburd (Criminology 53:133–157, 2015) has recently termed the ‘law of crime concentration at places’. Such findings suggest that the future locations of crime should—to some extent at least—be predictable. To date, methods of forecasting where crime is most likely to next occur have focused either on area-level or grid-based predictions. No studies of which we are aware have developed and tested the accuracy of methods for predicting the future risk of crime at the street segment level. This is surprising given that it is at this level of place that many crimes are committed and policing resources are deployed.

Methods

Using data for property crimes for a large UK metropolitan police force area, we introduce and calibrate a network-based version of prospective crime mapping [e.g. Bowers et al. (Br J Criminol 44:641–658, 2004)], and compare its performance against grid-based alternatives. We also examine how measures of predictive accuracy can be translated to the network context, and show how differences in performance between the two cases can be quantified and tested.

Results

Findings demonstrate that the calibrated network-based model substantially outperforms a grid-based alternative in terms of predictive accuracy, with, for example, approximately 20 % more crime identified at a coverage level of 5 %. The improvement in accuracy is highly statistically significant at all coverage levels tested (from 1 to 10 %).

Conclusions

This study suggests that, for property crime at least, network-based methods of crime forecasting are likely to outperform grid-based alternatives, and hence should be used in operational policing. More sophisticated variations of the model tested are possible and should be developed and tested in future research.

     

Gender Inequality and Patterns of Abuse Post Leaving

Drawing on Connell’s (Gender and power: Society, the person and sexual politics. California: Stanford University Press, 1987; Masculinities. Berkeley, CA: University of California Press, 1995) model of gender relations, this paper examines patterns of intimate partner violence among women who have recently left an abusive partner. In so doing, we attempt to better understand the social structural factors that shape the relations of power and control in intimate violent heterosexual unions. The data come from the first wave of a longitudinal prospective survey of 309 women who had left an abusive partner in the previous 3 years. Our data suggest that structured relations of inequality, namely relations of production, power and cathexis, shape women’s risk of abuse and harassment after leaving, and do so in ways that shape relations of coercive control. These results have implications for understanding the social context within which male violence against women occurs, and how this context constrains and/or enables women’s strategies for leaving and safety.

Effects of victim gender,victim sexual orientation,victim response and respondent gender on judgements of blame in a hypothetical adolescent rape

Objectives. Few studies have examined the judgements made towards adolescent rape victims, and none have investigated attributions towards gay male or lesbian adolescents. The current study examined the effects victim gender, victim sexual orientation, victim response, and respondent gender, on attributions of blame in the depicted rape of a 15‐year old adolescent. Methods. A total of 164 respondents read details of this assault before completing 15 attribution judgments. Results. Respondents were expected to attribute more blame to a victim who was male, gay, and who failed to resist the perpetrator. Male respondents were also expected to be more blaming of the victim than females. Overall these hypotheses were supported. Conclusion. Results are discussed in relation to the role gender stereotypes and homophobia play within attributions blame in sexual assault cases. Specifically, it seems male adolescent rape victims are subjected to the same negative stereotypes as male adult victims. Implications and ideas for future research are considered.
