About DNA databasing and investigative genetic analysis of externally visible characteristics: A public survey.

During the last decade, DNA profiling and the use of DNA databases have become two of the most employed instruments of police investigations. This very rapid establishment of forensic genetics is yet far from being complete. In the last few years novel types of analyses have been presented to describe phenotypically a possible perpetrator. We conducted the present study among German speaking Swiss residents for two main reasons: firstly, we aimed at getting an impression of the public awareness and acceptance of the Swiss DNA database and the perception of a hypothetical DNA database containing all Swiss residents. Secondly, we wanted to get a broader picture of how people that are not working in the field of forensic genetics think about legal permission to establish phenotypic descriptions of alleged criminals by genetic means. Even though a significant number of study participants did not even know about the existence of the Swiss DNA database, its acceptance appears to be very high. Generally our results suggest that the current forensic use of DNA profiling is considered highly trustworthy. However, the acceptance of a hypothetical universal database would be only as low as about 30% among the 284 respondents to our study, mostly because people are concerned about the security of their genetic data, their privacy or a possible risk of abuse of such a database. Concerning the genetic analysis of externally visible characteristics and biogeographical ancestry, we discover a high degree of acceptance. The acceptance decreases slightly when precise characteristics are presented to the participants in detail. About half of the respondents would be in favor of the moderate use of physical traits analyses only for serious crimes threatening life, health or sexual integrity. The possible risk of discrimination and reinforcement of racism, as discussed by scholars from anthropology, bioethics, law, philosophy and sociology, is mentioned less frequently by the study participants than we would have expected. A national DNA database and the widespread use of DNA analyses for police and justice have an impact on the entire society. Therefore the concerns of lay persons from the respective population should be heard and considered. The aims of this study were to draw a broader picture of the public opinion on DNA databasing and to contribute to the debate about the possible future use of genetics to reveal phenotypic characteristics. Our data might provide an additional perspective for experts involved in regulatory or legislative processes.

Simultaneous analysis of nuclear and mitochondrial DNA, mRNA and miRNA from backspatter from inside parts of firearms generated by shots at "triple contrast" doped ballistic models

When a firearm projectile hits a biological target a spray of biological material (e.g., blood and tissue fragments) can be propelled from the entrance wound back towards the firearm. This phenomenon has become known as "backspatter" and if caused by contact shots or shots from short distances traces of backspatter may reach, consolidate on, and be recovered from, the inside surfaces of the firearm. Thus, a comprehensive investigation of firearm-related crimes must not only comprise of wound ballistic assessment but also backspatter analysis, and may even take into account potential correlations between these emergences. The aim of the present study was to evaluate and expand the applicability of the "triple contrast" method by probing its compatibility with forensic analysis of nuclear and mitochondrial DNA and the simultaneous investigation of co-extracted mRNA and miRNA from backspatter collected from internal components of different types of firearms after experimental shootings. We demonstrate that "triple contrast" stained biological samples collected from the inside surfaces of firearms are amenable to forensic co-analysis of DNA and RNA and permit sequence analysis of the entire mtDNA displacement-loop, even for "low template" DNA amounts that preclude standard short tandem repeat DNA analysis. Our findings underscore the "triple contrast" method's usefulness as a research tool in experimental forensic ballistics.

Rachegefühle und posttraumatische Belastungsreaktionen bei Opfern von Gewalttaten

Theoretischer Hintergrund: Beschreibungen der posttraumatischen Belastungsstörung (PTB) besagen, dass Personen mit PTB häufig starke Rachegefühle erleben. Es besteht jedoch ein Mangel an bestätigenden empirischen Untersuchungen. Fragestellung: Der Zusammenhang zwischen Rachegefühlen und posttraumatischen Belastungsreaktionen wird untersucht. Methode: Die Daten wurden mittels Selbstbeurteilung bei 174 Opfern von Gewalttaten erfasst. Zur Messung der Belastungsreaktionen wurde die Impact of Event-Skala – revidierte Version (IES-R) eingesetzt. Ergebnisse: Rachegefühle korrelieren bedeutsam mit posttraumatischer Intrusion und Übererregung, jedoch nicht mit Vermeidung. Rachegefühle leisten einen Beitrag zur Varianzaufklärung, der über den Vorhersagebeitrag viktimologischer Standardvariablen hinausgeht. Der Zusammenhang wird jedoch erst mit wachsendem zeitlichen Abstand vom Ereignis enger. Schlussfolgerungen: Rachegefühle sind vermutlich als dysfunktionale Bewältigungsreaktion auf erlittene Ungerechtigkeit zu bewerten, jedoch nicht in der ersten Zeit nach einer kriminellen Viktimisierung.

Secondary victimization of crime victims by criminal proceedings

It is conceivable that criminal proceedings cause psychological harm to the crime victims involved, that is, cause secondary victimization. To investigate this hypothesis, negative and positive effects of criminal proceedings were investigated, as perceived by 137 victims of violent crimes who were involved in trials several years previously. Trial outcome and procedure variables were measured as potential causes of secondary victimization. Results show a high proportion of victims reporting overall negative effects. Powerful predictors were outcome satisfaction and procedural justice, but not subjective punishment severity, interactional justice, and psychological stress by criminal proceedings. The practical implications of the results pertain to whether victims should be advised to report the crime to the police or not, and to appropriate prevention and intervention measures of secondary victimization by criminal proceedings.

Criminal Solicitation, Entrapment, and the Enforcement of Law

This paper examines the optimal use of criminal solicitation as a law enforcement strategy. The benefits are greater deterrence of crime (due to the greater likelihood of apprehension), and the savings in social harm as some offenders are diverted away from committing actual crimes through solicitation. The costs are the expense of hiring undercover cops and the greater likelihood of punishment. The optimal use of solicitation balances these factors. The paper also examines the justification for the entrapment defense, which exonerates those caught in a criminal solicitation but who otherwise had no predisposition to commit a crime.

Deterrence and Incapacitation: Towards a Unified Theory of Criminal Punishment

Economic models of crime have focused primarily on the goal of deterrence; the goal of incapacitation has received much less attention. This paper adapts the standard deterrence model to incorporate incapacitation. When prison only is used, incapacitation can result in a longer or a shorter optimal prison term compared to the deterrence-only model. It is longer if there is underdeterrence, and shorter if there is overdeterrence. In contrast, when a fine is available and it is not constrained by the offender's wealth, the optimal prison term is zero. Since the fine achieves first-best deterrence, only efficient crimes are committed and hence, there is no gain from incapacitation.

Deterrence, Incapacitation, and Repeat Offenders

This paper develops an economic model of criminal enforcement that combines the goals of deterrence and incapacitation. Potential offenders commit an initial criminal act if the present value of net private gains is positive. A fraction of these offenders become habitual and commit further crimes immediately upon release from their initial prison term (if any). The optimal punishment scheme in this setting generally involves a finite prison term for first-time offenders (based on the goal of deterrence), and an infinite (life) sentence for repeat offenders (based on the goal of incapacitation).

A Simple Theory of Increasing Penalties for Repeat Offenders

A feature of many penal codes is that punishments are more severe for repeat offenders, yet economic models have had a hard time providing a theoretical justification for this practice. This paper offers an explanation based on the wage penalty suffered by individuals convicted of crime. While this penalty probably deters some first-timers from committing crimes, it actually hampers deterrence of repeat offenders because of their diminished employments opportunities. We show that in this setting, an escalating penalty scheme is optimal and time consistent.

Prevalence and trends of substance abuse in Harris County, Texas, 1989 to 1991

In the late 1980s, Harris County, Texas began experiencing an escalation of drug-related activities. Various indicators used in this analysis tracked drug-related trends from 1989 to 1991 to determine patterns for comparison of local (Houston/Harris County, Texas) to national levels.^ An important indicator of the drug scenario was drug-related activities among youths, which increased during the period of this study. The Harris County Juvenile Probation Department showed that among arrests for drug-related activities, felonies increased from 25% in 1988 to 53% in 1991. With the rise in drug-related crimes, and substance abuse among the student body, school districts were forced to institute drug education programs in an effort to curtail such activities.^ Law enforcement agencies in the county saw increased demands for their services as a result of drug activities. Harris County Sheriffs Department reported a 32% plus increase in drug-related charges between 1986 and 1991. Houston Police Department reported an increase of 109% for the same period.^ Data from the Harris County Medical Examiner, the National Institute of Justice's Drug Use Forecasting System (Houston), and drug treatment facilities around Houston/Harris County, Texas indicated similar drug usage trends. Over a four-year period (1988-91), the drugs most frequently detected during blood and urine analyses were cocaine, followed by marijuana, heroin, LSD, and methamphetamines.^ From 1988 to 1991, most drug rehabilitation organizations experienced increased demands for their services by approximately 35%. Several other organizations experienced as much as a 70 percent increase. Males accounted for roughly 70% and females about 30% of persons seeking treatment. However, the number of females pursuing treatment increased, thereby reducing the gender gap.^ Blacks in Houston/Harris County were at higher risk for drug usage among the general population, but sought treatment more readily than other ethnic groups. Whites sought treatment in similar numbers as Blacks, but overall the risk appeared smaller because they made up a larger portion of the Houston/Harris County population.^ This analysis concluded that drug trends for the Houston/Harris County, Texas did not follow national trends, but showed patterns of its own. It was recommended that other communities carry out similar studies to determine drug use trends particular to their local. ^

Commercial Sexual Exploitation and Missing Children in the Coastal Region of Sao Paulo State, Brazil

The commercial sexual exploitation of children (CSEC) has emerged as one of the world’s most heinous crimes. The problem affects millions of children worldwide and no country or community is fully immune from its effects. This paper reports first generation research of the relationship that exists between CSEC and the phenomenon of missing children living in and around the coastal regions of the state of Sao Paulo, Brazil, the country’s richest State. Data are reported from interviews and case records of 64 children and adolescents, who were receiving care through a major youth serving non-governmental organization (NGO) located in the coastal city of Sao Vicente. Also, data about missing children and adolescents were collected from Police Reports – a total of 858 Police Reports. In Brazil, prostitution is not a crime itself, however, the exploitation of prostitution is a crime. Therefore, the police have no information about children or adolescents in this situation, they only have information about the clients and exploiters. Thus, this investigation sought to accomplish two objectives: 1) to establish the relationship between missing and sexual exploited children; and 2) to sensitize police and child-serving authorities in both the governmental and nongovernmental sectors to the nature, extent, and seriousness of many unrecognized cases of CSEC and missing children that come to their attention. The observed results indicated that the missing children police report are significantly underestimated. They do not represent the number of children that run away and/or are involved in commercial sexual exploitation.

La configuración del tiempo mítico en Los recuerdos del porvenir de Elena Garro

En el presente trabajo abordamos la novela de Elena Garro Los recuerdos del porvenir a partir de los elementos de la narración configuradores de un "tiempo mítico". Este concepto, de larga tradición en Ia literatura hispanoamericana, sirve a la novelista para reflexionar sobre los procesos históricos, que ella juzga inevitablemente circulares; una penosa reiteración de los crímenes e injusticias del pasado. La voz narrativa, la creación de un campo semántico de la inmovilidad y la persistencia de un episodio real de la Conquista de México (la "Malinche"), son los elementos que, juzgamos, configuran el tiempo mítico y dan a esta novela una singular unidad ideológica y estilística.

Ronald Dworkin y los delitos sexuales : De la filosofía del derecho a la historia del derecho

El presente trabajo propone realizar un análisis interdisciplinario histórico-iufilosófico y de derecho tomando como eje el caso especial de los delitos contra la honestidad (actualmente delitos contra la integridad sexual) a la luz de cuatro aspectos de la teoría dworkiniana: el uso de la jurisprudencia y el precedente para resolver problemas jurídicos, el lugar de la moralidad en el derecho -especialmente en el argentino-, el concepto de "caso difícil" y el lugar del juez en su resolución. En este punto, pretendo mostrar cómo el objeto histórico se relaciona estrechamente con los desarrollos posteriores y problemas contemporáneos de la filosofía del derecho

La iniciativa privada en los delitos sexuales [Bs. As. 1863-1921]

Los delitos sexuales entre la segunda mitad del siglo XIX y principios del XX presentan problemas particulares en relación a la posibilidad de su imputación y castigo vinculados a la forma particular como se conciben estos crímenes. Propongo, a partir del análisis de expedientes judiciales, problematizar algunas de estas cuestiones partiendo desde el análisis de su concepción como "dependientes de iniciativa privada" y por tanto la necesidad de una "acusación particular" que implicó largos debates en los tribunales ya que la interpretación de esta situación tuvo más de una lectura posible: quedaban satisfechos los requerimientos de la ley con la denuncia o debía continuarse la participación de la parte hasta la misma sentencia, es decir, llegar hasta la vista de acusación? En este contexto se pone entonces en discusión la participación del Agente Fiscal en el proceso en tanto acusador y por lo tanto el interés del Estado como tal en la persecución de estos crímenes. Busco, simultáneamente mostrar las discusiones que se dieron en la práctica penal, que reflejan distintas formas de interpretar y pensar estos delitos; las razones implícitas en su persecución y castigo o por el contrario de su finalización y falta de pena
