论我国未成年犯社区矫正的必要性及可行性

当前,我国未成年人犯罪数量快速增长,且再犯罪率很高,这表明传统的未成年犯矫正工作已不适应现在矫正工作的需要。对未成年犯进行社区矫正,是近年来世界各国刑罚执行制度的一个发展趋势。它彰显了人道主义和人文关怀精神,有利于对未成年犯的再社会化,能够有效地克服对未成年犯科以监禁刑罚所产生的弊端。从未成年犯社区矫正的基本概念入手,论述我国未成年犯适用社区矫正的必要性及可行性。     

Profiles of Victimized Women Among the Child Welfare Population: Implications for Targeted Child Welfare Policy and Practices

Despite the call to address domestic violence along with child maltreatment, little information exists to guide services for victimized women involved with child welfare. Research shows that victimized women contend with multiple problems stemming from violent victimization. Unfortunately less is known about combinations of needs and resources among victimized women, especially for those involved with child welfare. Through an examination of needs and resources among families with child maltreatment and domestic violence, we aimed to help address this knowledge gap. Needs and resources among 1,229 victimized caregivers were examined using the National Survey of Child and Adolescent Well-being (NSCAW). Using latent class analysis, four distinct multivariate profiles of needs and resources among victimized caregivers were identified. Significant differences were found among the profile groups in the family violence they experienced in the 18 months following child welfare investigations. Based on these findings, we discuss implications for tailored practices to enhance the safety of victimized caregivers involved with child welfare. An earlier version of this paper was presented at the 9th Annual Conference of the Society for Social Work and Research, Miami, Florida in January 2005.     

The innovative performance of foreign-owned enterprises in small open economies

This paper compares the innovative performance of foreign-owned and domestically owned enterprises in five European countries. We look at innovation inputs, outputs, and examine how strong foreign-owned enterprises are embedded in the innovations systems of their host countries. We find that foreign ownership is associated with similar levels of innovation input, but higher levels of innovation output and higher labour productivity compared to domestic ownership. In four of the five countries, affiliates of foreign multinationals show a similar or even a higher propensity to co-operate with domestic partners than domestically owned enterprises.

Developmental Antecedents of Interpartner Violence in a New Zealand Birth Cohort

This paper examines the developmental antecedents of interpartner violence (IPV) victimization and perpetration in a New Zealand birth cohort (n = 828). The study found: (a) IPV occurred in 70% of relationships, with conflict ranging from minor psychological abuse to severe assault; (b) men and women reported similar experiences of victimization and perpetration of IPV; (c) exposure to abuse in childhood, family dysfunction and adversity, childhood and adolescent conduct problems, and alcohol abuse/dependence were significant predictors of IPV victimization and perpetration at age 25; and (d) the antecedents of IPV were largely the same for males and females, although the specific effects of these risk factors differed according to gender. Conduct disorder was more strongly predictive of IPV for females, whereas family adversity was more strongly predictive of IPV victimisation for males.     

Response to Tudor: Remorse-based Sentence Reductions in Theory and Practice

Steven Tudor defends the mitigation of criminal sentences in cases in which offenders are genuinely remorseful for their crimes. More than this, he takes the principle that such remorse-based sentence reductions are appropriate to be a ‘well-settled legal principle’—so well settled, in fact, that ‘it is among those deep-seated commitments which can serve to test general theories as much as they are tested by them’. However, his account of why remorse should reduce punishment is strongly philosophical in character. He sets to one side the many practical difficulties in implementing such reductions in the real world of criminal justice institutions so that he can focus on the question of whether a plausible account of sentencing can show that remorse should mitigate punishment. I contend that Tudor’s defense of such reductions is unpersuasive in certain respects. Yet even if it can be made more persuasive, I argue that the conditions that would have to be satisfied for remorse-based sentence reductions to be justifiably implemented are so many and various that they would likely exceed our abilities to responsibly grant them in real world legal contexts. I therefore claim that Tudor has failed to provide a defense of the ‘remorse principle’ that serves to explain or justify existing legal practices.

Effects of Perpetrator and Victim Gender on Negative Outcomes of Family Violence

Growing up in a violent home predisposes children to a host of behavioral and emotional difficulties. This study examined whether perpetrator and victim gender have an impact on depressive symptoms and aggressive behavior for victims of child physical abuse (CPA) and also with regard to witnessing interparental violence (IPV). This study also examined whether witnessing siblings being abused would elicit high levels of depressive symptoms and aggressive behavior. College students (n = 675) were assessed for both exposure to IPV and child physical abuse prior to age 18. Participants completed measures of depression and aggression. With regard to victims of CPA, participants victimized by both parents and those victimized by mothers only had significantly higher levels of aggression. For depressive symptoms, females having both parents as perpetrators or fathers only had significantly higher depressive symptoms. With regard to witnessing IPV, being abused by both parents was associated with endorsement of more aggression and depressive symptoms. With regard to witnessing sibling violence, the results were similar to those found for victims of CPA.

Characterization of human DNA in environmental samples

Environmental samples from indoor surfaces can be confounded by dust, which is composed largely of human skin cells and has been documented to contain roughly tens of micrograms of total DNA per gram of dust. This study complements previous published work by providing estimates of the quantity of amplifiable human DNA found in environmental samples from a typical indoor environment, categorized by the intensity of human traffic and visible quantity of dust. Dust was collected by surface swabbing standard 576 cm² areas in eight locations, and evaluated for total DNA quantity, presence of human DNA (mitochondrial and nuclear loci using conventional PCR), quantity of human nuclear DNA using quantitative PCR, and STR analysis. The total DNA content of 36 dust samples ranged from 9 to 28 ng/cm², and contained 0.2–1.1 pg/cm² of human DNA. Overall, human DNA was detected in 97% of 36 dust samples and 61% of samples yielded allele distributions of varying degrees of complexity when subjected to STR analysis. The implications of this study are twofold. First, the presence of dust in evidence can be a significant contamination source in forensic investigations because the human DNA component is of sufficient quality and quantity to produce allele calls in STR analysis. This can be effectively managed by implementing stringent protocols for collection and analysis of potential biological samples. A second implication is the use of dust as a source of evidence for identification of inhabitants within a defined location. In the latter case, a number of additional studies would be necessary to identify relevant pretreatments for environmental dust samples and to develop the necessary deconvolution techniques to separate the composite genotypes obtained.     

Interrogation of short tandem repeats using fluorescent probes and melting curve analysis: A step towards rapid DNA identity screening

Current forensic DNA profiling methods rely on the analysis of samples at specialised laboratories with an average turnaround time of several days. The ability to rapidly determine a partial profile of short tandem repeats at the point-of-arrest would be of great benefit to police forces around the world, for example enabling a suspect to be rapidly included or excluded from an investigation. We have developed a homogeneous PCR method for the interrogation of STR loci utilising fluorescent oligonucleotide probes and melting curve analysis. Alleles of the D18S51, TH01 and D8S1179 loci were differentiated and identified on the basis of target length and probe melting temperature. Assay performance was evaluated by comparing melting peak data with the AmpFlSTR^® SGM Plus^® system. The method is compatible with direct analysis of unpurified buccal swab samples, enabling a partial STR profile to be generated within 1 h.     

Examining the effects of paper type, pen type, writing pressure and angle of intersection on white and dark dominance in ESDA impressions of sequenced strokes--an application of the likelihood ratio

Questioned document casework can occasionally involve the sequencing of impressions. Although some conclusions can be drawn from looking at ESDA traces of intersections there is currently no way of assessing the strength of the observations made in any given case. Using a range of paper and pen types this work examines points of intersection and evaluates the results statistically in order judge the value of the results obtained.
