Investigating and adjudicating allegations of child sexual abuse are challenging tasks. In the present study, we examined defendant statements concerning charges of sexual abuse against young children in Swedish district court cases (87 defendants, 140 child complainants, tried between January 2010 to December 2015). A main objective was to test predictive factors for admissions of guilt using inferential statistical analyses. Furthermore, using qualitative thematical analysis, we sought to identify common patterns in the defendants’ explanations to the allegation. Approximately one-third of the defendants (31%) pleaded guilty during trial. Admissions of guilt were more likely if the defendant was young, if the child was young at the onset of abuse, if the child and perpetrator had an extrafamilial relationship, and if the defendant possessed child pornography. A conflict with the person who made the report (e.g. a custody dispute), a testimony from the child, a direct eyewitness, or an informal disclosure recipient were significantly more common in cases of denials. In the qualitative analysis, a range of alternative explanations behind the abuse allegations were identified. Legal professionals and investigators may benefit from considering these alternative hypotheses during their investigative and judicial work. 相似文献

In cases of disputed paternity, the scientific goal is to promote either the exclusion of a falsely accused man or the affiliation of the alleged father. Until now, in addition to anthropologic characteristics, the determination of genetic markers included human leukocyte antigen gene variants; erythrocyte antigens and serum proteins were used for that reason. Recombinant DNA techniques provided a new set of highly variable genetic markers based on DNA nucleotide sequence polymorphism. From the practical standpoint, the application of these techniques to paternity testing provides greater versatility than do conventional genetic marker systems. The use of methods to detect the polymorphism of human leukocyte antigen loci significantly increases the chance of validation of ambiguous results in paternity testing. The outcome of 2384 paternity cases investigated by serologic and/or DNA-based human leukocyte antigen typing was statistically analyzed. Different cases solved by DNA typing are presented involving cases with one or two accused men, exclusions and nonexclusions, and tests of the paternity of a deceased man. The results provide evidence for the advantage of the combined application of various techniques in forensic diagnostics and emphasizes the outstanding possibilities of DNA-based assays. Representative examples demonstrate the strength of combined techniques in paternity testing. 相似文献

Testing Legal Assumptions Regarding the Effects of Dancer Nudity and Proximity to Patron on Erotic Expression 总被引:1,自引:0,他引:1

A field experiment was conducted in order to test the assumptions by the Supreme Court in Barnes v. Glen Theatre, Inc. (1991) and the Ninth Circuit Court of Appeals in Colacurcio v. City of Kent (1999) that government restrictions on dancer nudity and dancer–patron proximity do not affect the content of messages conveyed by erotic dancers. A field experiment was conducted in which dancer nudity (nude vs. partial clothing) and dancer–patron proximity (4 feet; 6 in.; 6 in. plus touch) were manipulated under controlled conditions in an adult night club. After male patrons viewed the dances, they completed questionnaires assessing affective states and reception of erotic, relational intimacy, and social messages. Contrary to the assumptions of the courts, the results showed that the content of messages conveyed by the dancers was significantly altered by restrictions placed on dancer nudity and dancer–patron proximity. These findings are interpreted in terms of social psychological responses to nudity and communication theories of nonverbal behavior. The legal implications of rejecting the assumptions made by the courts in light of the findings of this study are discussed. Finally, suggestions are made for future research. 相似文献

During emerging adulthood, relationships with close friends may be particularly important and influential, yet most research on communication about sex-related topics focuses on emerging adults' communication with parents. Two hundred and five college students (61% female, mean age = 20.5) completed surveys about the frequency and quality of their sex-related conversations with same-sex best friends, and their sexual attitudes and behaviors. These conversations were more frequent between females, and between less religious youth. Sexually active youth discussed most topics more frequently than abstinent youth, although abstinent youth discussed abstinence more frequently. More frequent and comfortable conversations were generally associated with more liberal sexual attitudes, and more positive condom-related attitudes. Differential associations between the specific topics discussed and attitudes about sexuality, HIV, and condoms highlight the importance of examining multiple dimensions of sex-related communication rather than the unidimensional measures typically employed. 相似文献

Fifty-two mother-adolescent dyads (mean adolescent age = 16.3) participated in an observational study of communication about
health topics. The aim of the study was to examine mother-adolescent conversations about health issues—drugs/alcohol, sexuality,
nutrition/exercise—to determine the extent to which the mothers treat these issues similarly. Across conversations, mothers
spent more time asking questions than lecturing or discussing negative consequences. Mothers discussed negative consequences
less in the nutrition/exercise and sexuality conversations than in the drug/alcohol conversation. Mothers asked fewer questions
when discussing nutrition/exercise than drugs/alcohol, and lectured more in the nutrition/exercise conversation than in the
sexuality conversation. The results of this study have implications for intervention programmers advocating in the media that
parents “talk to your kids” about these health issues.

Most commercially available STR amplification kits have never been fully validated for low template DNA analysis, highlighting the need for testing different PCR kits and conditions for improving single-cell profiling. Here, current strategies rely mainly on adjusting PCR cycle number and analytical threshold settings, with a strong preference for using 30 amplification cycles and thresholds at 30–150 RFU for allele detection. This study aimed to (1) determine appropriate conditions for obtaining informative profiles utilizing a dilution series, and (2) test the outcome on single cells using the DEPArray™ technology. Four routinely applied forensic STR kits were compared by using three different amplification volumes and DNA dilutions down to 3.0 pg, while two well-performing kits were used for single/pooled leucocyte and sperm cell genotyping. Besides reduced costs, the results demonstrate that a 50%–75% PCR volume reduction was beneficial for peak height evaluation. However, this was counteracted by an increased artifact generation in diluted DNA volumes. Regarding profile completeness, the advantage of volume reduction was only prominent in samples processed with Fusion 6C. For single and pooled cells, ESIFast and NGMDetect provided a solid basis for consensus profiling regarding locus failure, although locus dropouts were generally observed as stochastic events. Amplification volume of 12.5 μL was confirmed as appropriate in terms of peak heights and stutter frequencies, with increased stutter peaks being the main artifact in single-cell profiles. Limitations associated with these analyses are discussed, providing a solid foundation for further studies on low template DNA. 相似文献

In this study we provide new evidence on the much-discussed effect of education on political participation by utilizing the quasi-experiment of twinning. By looking at the relationship between education and participation within monozygotic (MZ) twin pairs we are able to circumvent traditional sources of confounding of the relationship rooted in genes and early life family environment because MZ twins share both. The results of within-twin pair analyses based on surveys from the United States, Denmark and Sweden show that while the relationship between education and political participation is highly confounded by genes and/or familial environment in all three countries, a positive impact remains of years of education in the US and of high school completion in Denmark. No effect is found in Sweden. Robustness checks suggest that the observed effect is not confounded by within-twin pair differences in prenatal environment nor differential treatment during childhood, and, if anything, that it most likely constitutes a lower bound estimate. 相似文献

Social order and security depend on mutual cooperation between the police and the public. Since the majority of crime is not detected by the police itself, informal control is needed to ensure order in society. This article aims to describe the circumstances under which people´s willingness to cooperate with the police is enhanced. Recent studies show that public compliance and cooperation with authorities who carry out criminal proceedings are linked with the extent to which people perceive these authorities as trustworthy and legitimate. Importantly, trust in police procedural fairness leads to the perception that institutions of justice are legitimate, which in turn enhances people´s willingness to cooperate with them in order to fight crime and disorder. This normative perspective is supported in many European countries. However, evidence exists that instrumental judgements, which focus on one´s self-interest and on outcomes of the justice system, could also be important in some countries. Drawing on procedural justice theory, we examine the importance of normative and instrumental factors in eliciting people´s readiness to help the police fight crime in four Central European countries: the Czech Republic, the Slovak Republic, Hungary, and Poland. While the procedural justice pattern, i.e. the normative perspective, holds well in the Czech Republic and Hungary, in other analysed countries trust in police effectiveness or fear of crime, i.e. instrumental judgements, are relevant too. 相似文献
