The age estimation of blood stains up to 30 days old using visible wavelength hyperspectral image analysis and linear discriminant analysis

A novel application of visible wavelength hyperspectral image analysis has been applied to determine the age of blood stains up to 30 days old. Reflectance spectra from selected locations within the hyperspectral image, obtained from a portable instrument, were subjected to spectral pre-processing. This was followed by the application of a linear discriminant classification model, making estimations possible with an average error of ± 0.27 days for the first 7 days and an overall average error of ± 1.17 days up to 30 days. This is also the first reported study of the determination of the age of fresh blood stains (less than one day old) with an error of ± 0.09 h. The studies have been made under controlled conditions and represent, at this stage, proof of concept results but also are the most accurate age estimation results for measurements between 0 and 30 days reported to date. The results are consistent with well-established kinetic processes suggesting that the pre-processing stages described are revealing spectroscopic changes which are reliably following the time dependent oxidation of HbO₂. The potential for parameterisation of environmental factors to make the method generally applicable at crime scenes is discussed, along with the developments required to further improve classification and to make the instrument genuinely portable.     

TWO CITIES Urban Migration and Settlement in Nineteenth-Century Sweden

This article examines how migrants settled and formed families in two Swedish towns—Linköping and Sundsvall—with different occupational structures during industrialization. Sex- and socio-economic differentials in the rural–urban and urban–urban migration are discussed, as well as persistence rates in the new urban environment among different social groups. Analysis of in-migration and marriage patterns shows that social and geographical endogamy are equally significant in the two towns. Migrants tended primarily to marry migrants and town-born primarily to marry town-born. Moreover, relatively closed marriage boundaries were found among the in-migrants: those that came from an urban background tended to find an “urban partner.”     

Eliciting cues to deception by tactical disclosure of evidence: The first test of the Evidence Framing Matrix

Purpose. Research on real‐life suspect interviews shows that disclosure of evidence is a very common tactic and that it occurs in all phases of the interview. It is therefore remarkable that there is hardly any research on the effectiveness of different disclosure tactics. The aim of this study was to examine the effects of three different disclosure tactics: presenting the evidence early and two versions of the Strategic Use of Evidence (SUE) technique. Methods. For the SUE‐Basic technique (SUE‐B), the evidence was disclosed late in the interview. For the SUE‐Incremental technique (SUE‐I), we used a stepwise disclosure tactic derived from the so‐called Evidence Framing Matrix. The tactic consists of revealing evidence of increasing strength and precision. A mock‐theft scenario was employed with 195 participants who were randomly allocated to one of six conditions: guilty or innocent suspects were interviewed with one of the three techniques. Two measures of inconsistency were used as dependent variables: statement‐evidence inconsistency and the newly developed within‐statement inconsistency. Results. By interviewing with SUE‐I, strong cues to deception were elicited, especially for the statement‐evidence inconsistency variable. For the SUE‐B, significant but smaller differences between guilty and innocent suspects were obtained. Conclusions. We found that both when and how the evidence was disclosed moderated the effectiveness of disclosure. With respect to when, it was more effective to disclose the evidence late (vs. early), and with respect to how, it was more effective to disclose the evidence in a stepwise (vs. direct) manner. The tactical aspects of evidence disclosure are discussed.

Pre-parliamentary backgrounds of Australian major party MPs: effects on representation

Legislative recruitment patterns are an important study in the field of political science, given their consequences for the practice of parliamentary government. The Australian parliament is a bicameral legislature, including a powerful elected upper chamber. This article details the pre-parliamentary party backgrounds of Australia's two major parties, the Australian Labor Party (ALP) and the Liberal/National Party coalition (LNP) in the 39th Australian Parliament (1998–2001). It is hypothesised that the pre-parliamentary backgrounds of Upper House major party MPs are dominated by central party experience, while the party experience of Lower House MPs is more significantly localised. It is further hypothesised that these differences in pre-parliamentary backgrounds will remain constant when the respective parties are evaluated individually. This appears something of a paradox given that one would expect central party activists to prefer a legislative career in the lower house, affording them greater ministerial opportunities. The causes of such deviations from expected background distributions amongst legislators is explored. Contrary to traditional findings, upper house MPs are highly partisan, performing functionary roles to assist their lower house colleagues secure re-election. Strong senator partisanship is reflected in the non-parliamentary practice of major party senators. Such partisanship is a consequence of party selection methods, the electoral system and pre-parliamentary party backgrounds, not necessarily the uniquely powerful Australian Senate. It is therefore significant in the Australian polity and may have consequences for less powerful and/or unelected upper chambers in other bicameral parliaments.

Violence against Women in Scandinavia: a Description and Evaluation of two new Laws Aiming to Protect Women

Violence against women by a present or former male partner has over the last decade been given a higher priority in the political discussion in all of the Scandinavian countries. Increasingly, violence in intimate relationships is viewed as a public rather than a private matter in these countries. With this change in attitudes and levels of political interest, higher expectations are placed on official authorities, including the criminal justice system, to deal actively with this social problem. In all of the Scandinavian countries it may, for example, be decided by a prosecutor that a woman should be protected from a man by issuing a restraining order. Moreover, a new offence called ‘gross violation of a woman's integrity’ was introduced into the Swedish penal code in 1998. With this offence, less serious but repeated violent acts committed by a man against a present or former female partner are to be judged as one serious offence. The stipulated sanction for this offence is imprisonment between 6 months and 6 years. The purpose of this article is to evaluate how the police, the prosecutors and the courts deal with this new offence. The article also present results from an evaluation of restraining orders in Sweden.     

Japan’s Ivory Trade in the Face of the Endangered Species Convention

Abstract

Commercial trade in ivory remains one of the major threats to the survival of an iconic wildlife resource: the elephant, in particular the African species (Loxodonta africana). At its 2016 Johannesburg meeting, the Conference of the Parties to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) adopted by consensus an urgent call for the closure of domestic markets for ivory. The only Party which has openly defied that call is Japan – claiming that its own domestic ivory market is strictly controlled, and does not contribute to elephant poaching elsewhere. The present study analyzes that claim in light of the evidence, including the country's legislation (as recently amended) and its application in practice (as documented by multiple recent surveys). The author's findings do not support Japan's claim to a sweeping exemption from the global ban agreed by the CITES Conference. On the contrary, in view of serious shortcomings in the Government's current legislative and administrative controls over the ivory trade (especially with regard to internet transactions), the author recommends effective termination of Japan's domestic ivory market; and pending such closure, a reclassification of Japan in category 2 of the CITES legislation list (‘legislation believed not to meet all the requirements for CITES implementation’).     

Understanding Victim Support as Crime Prevention Work: The Construction of Young Victims and Villains in the Dominant Crime Victim Discourse in Sweden

Starting from the observation that a new victim category has emerged in the form of the ‘young crime victim’, this article explores the notion of support to young crime victims as crime prevention work, considering it as an important constituent of the dominant crime victim discourse among support professionals. In the context of the support work, the (young) ‘victim’ and the (young) ‘villain’ provide mutually necessary counterparts constructed in relation to each other. Corresponding to this division, two approaches in criminal and crime prevention policy and practice are then analysed using Garland's notions of ‘the criminology of the self’ and ‘the criminology of the other’. The first of these strategies is generally associated with rehabilitative measures (with the resulting normalization of the crime, its victims, and villains), while in the second punitive measures remain the norm (with the crime, its victims, and villains becoming ‘Otherized’). Yet, as shown within the context of rehabilitation organized as support to young crime victims, both of these (at first glance mutually contradictory) discourses are drawn upon and operationalized by the professional support staff constructing images of young victims and villains in their daily work. Help-seeking youths resistant to identifying as victims remain represented as (possible future) villains.
