在后现代主义中建构犯罪学理论

现代犯罪学留给我们至少11种互不融合的理论结构,但它们的要塞基础随着现代社会理论的消亡而土崩瓦解。在后现代社会里,能否建构起一种一般性的犯罪学理论或融合不同的犯罪学理论?怀疑不是绝望的理由,而是意识到需要采取创造性行动的证据。     

Consensus on validation of forensic voice comparison

Since the 1960s, there have been calls for forensic voice comparison to be empirically validated under casework conditions. Since around 2000, there have been an increasing number of researchers and practitioners who conduct forensic-voice-comparison research and casework within the likelihood-ratio framework. In recent years, this community of researchers and practitioners has made substantial progress toward validation under casework conditions becoming a standard part of practice: Procedures for conducting validation have been developed, along with graphics and metrics for representing the results, and an increasing number of papers are being published that include empirical validation of forensic-voice-comparison systems under conditions reflecting casework conditions. An outstanding question, however, is: In the context of a case, given the results of an empirical validation of a forensic-voice-comparison system, how can one decide whether the system is good enough for its output to be used in court? This paper provides a statement of consensus developed in response to this question. Contributors included individuals who had knowledge and experience of validating forensic-voice-comparison systems in research and/or casework contexts, and individuals who had actually presented validation results to courts. They also included individuals who could bring a legal perspective on these matters, and individuals with knowledge and experience of validation in forensic science more broadly. We provide recommendations on what practitioners should do when conducting evaluations and validations, and what they should present to the court. Although our focus is explicitly on forensic voice comparison, we hope that this contribution will be of interest to an audience concerned with validation in forensic science more broadly. Although not written specifically for a legal audience, we hope that this contribution will still be of interest to lawyers.     

Power,politics and policy in the appropriation of urban wetlands: the critical case of Sri Lanka

Little is known about the drivers and governance strategies of appropriation of urban nature in the global south. We compare urban land-grabbing in the city of Colombo, Sri Lanka, with broader understanding of rural land-grabbing in the developing world. We show that the colonial legacy of appropriation and alteration of urban wetlands in Colombo has attained new heights in the neo-liberal period. This cyclical process has caused acute irreversible damage to the wetland ecosystem and a vast majority of the urban poor, with the marginalised continuing to suffer dispossession and environmental hazard. In recognition of the inherent limitations of ‘uncontrollable’ hybrid ecologies, potent social struggles have emerged to resist the continued appropriation agenda. As this cycle is perpetuated, broader social struggles for democratic urban governance have overtaken the pursuit of narrow political-economic goals and internal policy reform.     

Surveying the terrain: Current issues in the prevention and management of sexually abusive behaviour by males

Abstract

This paper focuses on critical issues and challenges concerning five areas: the prevention of sexually aggressive behaviour; inter-agency collaboration; groupwork programmes for adult offenders; eligibility levels regarding services for adolescent offenders; and professional issues.

Key messages which emerge are: the need to prevent punitive parenting in early childhood; the importance of healthy intra-agency processes as a foundation for effective inter-agency working; ensuring careful selection of clients for groupwork programmes; developing a tiered set of service thresholds for adolescent offenders; and the need to sustain the emotional responsiveness of staff.     

The forensic evaluation and treatment of children: ethics and values

This article will review the history of ethics and values in the forensic evaluations and treatment of children. Topics to be discussed include paternalism, advocacy, parental responsibility, and legal doctrine of parens patriae. Various aspects of the treatment of children, including medications, behavior modification, and psychotherapy, are also examined for ethical considerations. Agency consultation in conflicts of ethics that are associated with public laws are also addressed. The ethical implications of the use of children in any research as research subjects is also addressed.     

Immunofixation of complement component C3 phenotypes in bloodstains after cellulose acetate electrophoresis

The determination of the polymorphic C3 phenotypes was accomplished by electrophoresis on cellulose acetate followed by immunofixation. The three common phenotypes resulting from the two common codominant alleles C3S and C3F were clearly distinguishable in blood and bloodstain samples. Storage and degradation of C3 in blood samples as well as the stability of C3 in dried bloodstains is discussed.     

An empirical estimate of the precision of likelihood ratios from a forensic-voice-comparison system

An acoustic-phonetic forensic-voice-comparison system was constructed using the time-averaged formant values of tokens of 61 male Chinese speakers' /i/, /e/, and /a/ monophthongs as input. Likelihood ratios were calculated using a multivariate kernel density formula. A separate set of likelihood ratios was calculated for each vowel phoneme, and these were then fused and calibrated using linear logistic regression. The system was tested via cross-validation. The validity and reliability of the results were assessed using the log-likelihood-ratio-cost function (C(llr), a measure of accuracy) and an empirical estimate of the credible interval for the likelihood ratios from different-speaker comparisons (a measure of precision). The credible interval was calculated on the basis of two independent pairs of samples for each different-speaker comparison pair.
