Application of Infrared and Raman Spectroscopy in Paint Trace Examination

Raman spectroscopy has proved to be a promising technique in forensic examinations, where optical microscopy, micro‐infrared spectroscopy, and microspectrophotometry in the visible and UV range are used for identification and differentiation between paint traces. Often no organic pigments are detected using Fourier transform infrared spectroscopy, because their content in a trace is usually undetectable. Application of a micro‐Raman spectrometer equipped with several excitation lasers helps forensic experts in paint analysis enabling identification of main pigments. Three cases concerning comparative examination of car paint are discussed in detail. The comparison of Raman spectra of paint chips found on clothing of a victim or smears found on body of a damaged car to these of paint chips originated from the suspected car enabled us to identify the car involved in the accident. When no comparative material is available, the method can be useful in establishing the color and make of the car.     

The enhancement effect of social and employment integration on the delay of recidivism of released offenders trained with the R & R programme

Abstract

The aim of this study is to assess the extent to which social and employment integration enhances the efficacy of social–cognitive training carried out in prison through a Spanish adaptation of the Reasoning & Rehabilitation (R & R) programme. A quasi-experimental design was used to compare a group of inmates who received only social–cognitive training with a group of inmates who also received social and employment integration and with a comparison group who received neither of these interventions. The total sample was composed of 117 repeat offenders, serving sentence for property offences, drug dealing and offences against the person. The results obtained through a Kaplan–Meier survival analysis after a 6-year follow-up indicate that both intervention groups are significantly different from the comparison group. The group that received social and employment integration had the highest level of delayed recidivism, but the difference with the group that only received social–cognitive training was not statistically significant. The results are discussed in relation to the Good Lives Model and to the Risk–Needs–Responsivity Model of offender rehabilitation.     

From partisan to pluralist ideology: the changing practices of democracy through Spain’s 20th-century constitutional moments

This article explores the practices of democracy in Spain through the lens of its 20th-century constitutional moments, namely, those around the 1931 and the 1978 constitutions, with the aim of elucidating its changing ideological significance. Whereas in 1931, supporting democracy had a strongly partisan meaning, as every endorsement of the democratic ideal entailed a conflicting understanding of the Republic’s democratic character, in 1978 it gave rise to an integrative form of pluralism. Even if the former has left a deep imprint on Spanish politics, anticipating a kind of seemingly irreconcilable opposition between left and right, the latter has proved instrumental in the consolidation of the new democratic regime. After the institutional distortion of democracy during the four-decade dictatorship’s ‘organic democracy’, since 1977 the ideal of democracy was thoroughly recast into a pluralist ideology. Unlike views describing it as a consensual regime, the article argues that the politics of consensus tested since the 1977 constitutional debates paved the way for the accommodation of democratic pluralism; furthermore, the culture of pacts it contributed to set up has continued to inspire a new form of adversarial, parliamentary politics well beyond the transition years.

Improved estimation of postmortem interval based on differential behaviour of vitreous potassium and hypoxantine in death by hanging

Many formulae are available to estimate the relation between the potassium ([K+]) and hypoxantine ([Hx]) concentration in the vitreous humour and the postmortem interval (PMI). Typically these have been based on a correlation test and linear regression using the postmortal interval as the independent variable and [K+] or [Hx] as the dependent variable in order to estimate the confidence interval. However, a recent study has shown that a more precise measurement of PMI can be obtained if [K+] is used as the independent variable. The regression lines obtained from the most recent deceased subjects with forensic relevance received for autopsy in the Institute of Legal Medicine are [K+] = 5.589 + 0.174PMI and [Hx] = 26.459 + 3.017PMI, by changing the variables, we obtain PMI=3.967[K+] - 19.186 (R2 = 0.688, P < 0.001) and PMI = 0.172 [Hx] + 0.170 (R2 = 0.518, P < 0.001). In this paper we propose the cause of death as an extra factor which modifies the relationship and gives even greater precision in estimating PMI. In cases of death by hanging the results are considerably improved with [K+] = 5.224 + 0.225PMI and [Hx] = 15.161+4.957PMI, respectively, and consequently, PMI = 3.631[K+] - 17.334 (R2 = 0.818, P< 0.001) and PMI = 0.153[Hx] - 0.368 (R2 = 0.757, P < 0.001): the slope is less and the precision is obviously enhanced.     

论社会主义市场经济法律体系——兼论社会主义市场经济法律体系与有中国特色社会主义法律体系的关系

<正> “依法治国,建设社会主义法治国家”,是邓小平理论的重要内容。要依法治国,建设社会主义法治国家,必须加强法制建设;要加强法制建设,必须以“加强经济法制建设”为重点;要加强经济法制建设,必须“加强经济立法”。加强经济立法的目标,是建立和完善“社会主义市场经济法律体系”。可见,建立和完善社会主义市场经济法律体系,是实行依法治国,建设社会主义法治国家的需要,是坚持邓小平理论的内在要求。但是,中国法学界对社会主义市场经济法律体系的研究还比较肤浅,在社会主义市场经济法律体系的概念、结构以及建立和完善社会主义市场经济法律体系的意义和对策等问题上,还存在着不少意见分歧。因此,对社会主义市场经济法律体系的研究亟待深入。

Childhood abuse and neurocognitive performance in adulthood: a preliminary study of executive functioning in offenders

Childhood abuse has an important negative influence on long-term executive functioning performance. Although this has been studied in non-offenders (controls), few investigations have examined offender samples. The aims of this study were: to study the influence of childhood abuse history on adulthood executive functioning in offenders, and to examine whether executive performance is affected differentially by different abusive events. It was found that in comparison with controls (n?=?17) and with non-abused offenders (n?=?22), the abused offenders (n?=?18) have poorer performance on psychomotor-cognitive processing speed and cognitive flexibility. In abused offenders, it was also found that physical abuse events primarily and significantly affected adulthood performance in these cognitive abilities. In conclusion, this study helps us to know, preliminarily, the neurocognitive profile of abused offenders and how different abusive events suffered in childhood (e.g. physical and emotional abuse) differentially affect executive functioning of this sample.     

The Relationship Between Mental Disorders and Types of Crime in Inmates in a Brazilian Prison

This cross‐sectional study conducted in prisons in the city of Salvador, Bahia, Brazil, investigated the association between the presence of psychiatric disorders in 462 prisoners and the types of crimes committed by them. Psychiatric diagnosis was obtained by means of the Brazilian Portuguese version of the Mini‐International Neuropsychiatric Interview. A statistically significant association was found between some psychiatric disorders and specific groups of crime: lifelong substance addiction with sex crimes and homicide; antisocial personality disorder with robbery and with kidnapping and extortion; borderline personality disorder with sex crimes; and lifelong alcohol addiction with fraud and conspiracy and with armed robbery and murder. It was concluded that the mental disorders considered more severe (psychosis and bipolar disorder) were not associated with violent crimes, suggesting that the severity of the psychotic disorder may be the factor that has caused psychosis to be associated with violent crimes in previous studies.     

Interest groups in Brazil: a new era and its challenges

This article provides general and specific insights into Brazil's developing interest group system. In doing so, it presents a theoretical foundation for understanding this group activity, past and present. The general insights of the role of interest groups under limited political participation and authoritarian regimes down to the 1980s plus the period of democracy since then, provide background for the specific insights of the article. The specifics focus on three aspects of Brazil's contemporary interest group activity: (1) utilization of a neo-institutional analytical approach for understanding the interest group environment; (2) an analysis of the types of lobbying activity that takes place in Brazil today, including a case study; and (3) an assessment of the level of development of the group system by placing it in a comparative perspective with both advanced liberal democracies and other Latin American countries. The findings show that Brazil is, indeed, taking on many of the characteristics of a developed interest group system; but its past, its political culture, its political economy, and, paradoxically, its new-found status as an international power, work to present several challenges to its group system and thus to a full democratization of the country.
