A forensic international market survey of condom lubricants and personal hygiene products using ATR-FTIR coupled to chemometrics

Condom residues may be encountered in forensic investigations as traces in sexual assault or rape cases. Casework studies have shown the value of distinguishing condom residues from other types of personal products used by women. However, up to now, there has been no investigation of their chemical variability within an international context. This work employed attenuated total reflectance Fourier transform infrared spectroscopy with chemometrics to provide objective characterisation of condom lubricants and personal hygiene products from the international market. 166 samples were obtained covering five major classes of products likely to be used by women. Principal component analysis distinguished most major classes based on their spectral profiles, with subsequent support vector machine models yielding discrimination accuracies over 90%. A two-step approach was subsequently developed and enabled both classification and a discrimination accuracy of 100%. This could provide greater confidence in chemical discrimination of residues from these products when conducting investigations and help assess the origin of the chemical profile obtained. Further testing using three validation sets produced an identification accuracy of 100% for generic classes, which may allow investigative leads to be more readily obtained from recovered evidence.     

Crowd Situations and their Policing from the Perspective of Finnish Police Officers—a Case Study of Finnish Police Knowledge

This study explores crowd situations from the perspective of the Finnish police. The qualitative data consist of focused face-to-face interviews with police officers (n = 15). The results of these interviews indicate that special crowd control units have shifted from being an innovation to being an ordinary part of public order policing, despite the infrequent use of these units. Furthermore, police knowledge concurrently involved diversity and polarity. Crowd situations vary from political protests to sporting events and street festivals, and the police play multiple roles and apply diverse measures and tactics depending on the situation. Polarity is linked to the way the police perceive different crowds and crowd events as ‘easy’ and ‘ordinary’ or ‘difficult’ and ‘deviant’. Finally, tension emerges between national and global aspects within police knowledge. This tension is linked to how police perceive crowd events and public order policing in terms of the past, the present, and the future.     

Determination of gamma-hydroxybutyrate (GHB) and its precursors in blood and urine samples: a salting-out approach

Gamma-hydroxybutyrate (GHB) is an increasingly popular drug of abuse that causes stimulation, euphoria, anxiolysis or hypnosis, depending on the dose used. Low doses of the drug are used recreationally, and also implicated in drug-facilitated sexual assaults. Because of the unusually steep dose-response curves, accidental GHB overdosing, leading to coma, seizures or death can occur. Being a controlled substance, GHB is often substituted with its non-scheduled precursors gamma-butyrolactone (GBL) and 1,4-butanediol (BD), which are rapidly metabolized into GHB in the body. Here we describe an assay for GHB, GBL and BD in blood and/or urine samples. GHB and BD were extracted from diluted 200 microL aliquots of samples with t-butylmethylether (plus internal standard benzyl alcohol) in test tubes preloaded with NaCl. After acidification and centrifugation the solvent phase was transferred to a test tube preloaded with Na(2)SO(4), incubated for 30 min, centrifuged again, and evaporated in vacuum. The residue was mixed with N-methyl-N-trimethylsilyl-trifluoroacetamide (MSTFA) in acetonitrile, and injected into a GC-MS. When analyzing GBL, the salting-out step was omitted, and analysis was performed with a GC-FID apparatus. As revealed by the validation data this procedure is suitable for quantitative determination of GHB and its precursors in blood and/or urine samples.

Is Ethnic Diversity Bad for Any Dimension of Social Capital? Trust,Networks and Voluntarism in Norwegian Communities

Ethnic diversity has been posed as a threat to social capital, but results from existing research are inconclusive. This study takes as its starting point that different aspects of social capital may be influenced differently by ethnic diversity and uses one specific welfare state context – Norway – to explore such variations. Analysing an original dataset, nine different measures are used to explore three dimensions of social capital in 61 communities in Norway, amongst the majority population and residents with immigrant background. The results suggest, first, a differentiated impact of ethnic heterogeneity on trust. Ethnic diversity is negatively associated with spatially bounded forms of trust, but not with generalized trust. Second, a negative association with traditional forms of voluntarism is found – albeit this latter relationship is much weaker than the former. Third, the results suggest that these relationships are fairly similar across different (immigrant) groups. Although residents with immigrant background typically express lower levels of generalized trust than the majority population, the relative differences between residents living in diverse or homogeneous communities are limited. Given its strong institutions Norway could be seen as a least likely case for studying the impact of ethnic diversity on social capital. On the one hand, effects are more limited than what has been found in studies from the United States. On the other hand, the fact that effects are found on community trust and volunteering indicates that this type of societal model can indeed be affected by ethnic diversification.     

Regulation for Safe Food: A Comparison of Five European Countries

This article explores food safety regulation in five European countries by comparing their main legislation and organizational characteristics. The aim is to gain insight into the particular characteristics of food safety regulation, understand major differences and similarities, and reach a firmer understanding of how regulation evolves. Food safety regulation concerns vital questions, and is a field with a long history. Food scandals – in particular the 1996 BSE crisis – and European integration have prompted major changes. The BSE scandal revealed important underlying conflicts of interest and dilemmas concerning the twin objectives of ensuring safe food while also ensuring honest trade in food. This led to a questioning of existing structures and paved the way for new regulation. The authors' main finding is that food safety regulation has similar origins, addresses similar tasks, and raises similar problems and conflicts in all five countries. A tension between protecting public health and paying heed to business interests, and a struggle for control over this policy field between the administrations of health and agriculture, are common features. However, the configuration of food safety regulation in legislative and organizational terms varies. The comparative focus reveals that national context and history are important for understanding change. This leads to the conclusion that the framing and reframing of the field depend largely on how it is structured and regulated initially, as well as on the constellations of interests and values that are operative and legitimate in each context.     

Reintegration and the relevance of social relations: the case of Lebanon

The DDR process that took place in Lebanon after the internal wars (1975–89), based on the Ta'if Accord (1989), was not co-ordinated by any international organisation. This paper assesses the reintegration of a number of combatants of one of the militias, the Lebanese Forces, placing particular emphasis on the context in which it unfolded. A programme of reintegration into the Lebanese Armed Forces (LAF) was proposed to the ex-combatants, but because of the high number on one side and because of the situation within the LAF itself (a pluri-religious organisation under reorganisation) this programme had little effect on the process. Instead the majority of the ex-combatants came to rely on their family and network established within the militia for their social and economic reintegration. This study finds that there has been little rupture between life as combatants and life as civilians. Three contextual factors were particularly important: the small size of the country, the rhythm of the war where periods of combat alternated with periods of calm, and the close contact combatants managed to keep with their family, work, schools and universities. A key lesson for DDR processes more generally stems from the study: DDR initiatives are likely to be most effective when they work alongside and augment indigenous positive social processes contributing to reintegration.     

What helps and what hinders the process of surviving the suicide of somebody close?

This paper presents similar findings about the lack of support and understanding for people bereaved through suicide from four different countries and reports on each country's unique response to this challenge. This paper reports on presentations made at the conference workshop of the International Association for Suicide Prevention meeting in Chennai in 2001, and on participants' suggestions of how best to help the bereaved.     

Jurors' Perceptions of Adolescent Sexual Assault Victims Who Have Intellectual Disabilities

Children and adolescents with intellectual disabilities are especially likely to be sexually abused. Even so, their claims are not likely to be heard in court, possibly because people assume that jurors will not believe them. We tested this assumption in a mock-trial study in which 160 men and women watched videotaped excerpts from an actual trial. As predicted, when the 16-year-old sexual assault victim was portrayed as mildly mentally retarded instead of as having average intelligence, jurors were more likely to vote guilty and had more confidence in the defendant's guilt; considered the victim to be more credible and the defendant to be less credible as witnesses; and rated the victim as more honest, less capable of fabricating the sexual abuse accusation, and less likely to have fabricated the sexual abuse accusation. Men and women were affected similarly by the disability manipulation, but women were generally more pro-prosecution in their case judgments and perceptions than were men. Finally, jurors who had more liberal views toward persons with disabilities were more likely than other jurors to make pro-prosecution judgments on measures of guilt. Implications for psychological theory and the law are discussed.
