There were two purposes to the current set of studies. The first was to test the validity of the Adaptiveness of Defenses Scale (ADS), a new measure developed to assess variability within ego defense mechanisms. Study 1 addressed the validity of the ADS with a sample of 104 male undergraduates. The ADS was hypothesized to account for significant unique variance on dependent measures (the PAI, ECR, and final grade in introductory psychology) beyond that accounted for by the Defense-Q. Regression analyses showed that a different pattern emerged. The Defense-Q and ADS accounted for different aspects of the dependent variables, with the Defense-Q predicting PAI Somatization scale scores and the ADS predicting ECR avoidance scale scores. Study 2 addressed the validity of the ADS with a sample of 64 male federal inmates. The ADS was hypothesized to account for significant unique variance on dependent measures (the BPI, PCL-R, and PAS) beyond that accounted for by the Defense-Q. As with Study 1, the two measures tended to predict different aspects of the dependent measures. The Defense-Q predicted immature defense factor scores on the BPI as well as BPI total score, and it predicted affective instability factor scores on the PAS, as well as PAS total score. Conversely, the ADS predicted PCL-R total and Factor 1 scores. The relation between the Defense-Q ADP similarity score and the PCL-R interpersonal facet was significantly positive, while the relation between the ADS total score and this facet was significantly negative. The results of Studies 1 and 2 suggest that the ADS captures an aspect of defensive functioning different from that measured by the Defense-Q, likely related to interpersonal functioning. Study 3 examined the relation between defenses (measured by the Defense-Q and ADS) and correctional variables (offense history, institutional incidents, institutional charges, urinalysis outcomes, and correctional program outcomes), as well as examined Aboriginal and non-Aboriginal differences. The differences between Aboriginal and non-Aboriginal inmates tended to show that non-Aboriginal inmates were older and had more aggressive criminal histories as well as higher PCL-R total and Factor 1 scores. They also tended to have more problematic institutional adjustments, likely because of their higher levels of psychopathy. The Defense-Q was significantly related to general offence history for Aboriginal inmates and the ADS was significantly related to violence history for non-Aboriginal inmates, but other significant relations were sparse. The results of the current series of studies provides preliminary support for the idea that individual defenses have their own ranges of adaptiveness, as the ADS scores male undergraduates and male inmates were significantly different for the same defenses. Given the pattern of the relations of the ADS to the dependent variables, it appears that the ADS is sensitive to interpersonal functioning.

This study examined the extent to which the lifetime traumatic and stressful experiences of incarcerated youths cluster in meaningful and understandable ways. It also evaluated the differential effects of various types of these events on a variety of psychosocial outcomes for this population. The sample consisted of 185 incarcerated male and female adolescents (ages 12-19). Confirmatory factor analysis results suggested that an empirically-derived model based on negative event type (i.e., Community Violence, Interpersonal trauma/stress, and Loss) better predicted how negative life events group together on the Adolescent Stress and Trauma Exposure Questionnaire -Version 2 (ASTEQ-2) than the model based on a traditional framework of traumatic versus less severe stressful events in this population. Further, the empirically-derived factors varied substantially in their ability to uniquely predict different psychosocial outcomes, assessed with the Trauma Symptom Checklist for Children (TSC-C) and the Structured Interview for Disorders of Extreme Stress, Adolescent version (SIDES-A). For example, the Interpersonal trauma/stress factor accounted for substantially more unshared variance than other factors in TSC-C Depression and Posttraumatic stress outcomes, while the Community Violence factor accounted for substantially more unshared variance than other factors in TSC-C Anger and SIDES-A Self-Destructive Behavior outcomes. Results both partially support prior research, while also exposing its limitations with regard to the inappropriate generalization of a culturally bound trauma framework to traditionally marginalized adolescent populations.

Abstract This study is to elucidate the possibility of DNA fragment identification method in the forensic detection of marine microalgae (Chlorella sp. and Nannochloropsis oculata) from human (Homo sapiens) body by 3% agarose gel electrophoresis of amplification fragments via PCR-amplified ribosomal gene small subunit (SSU) rDNA molecules as primers, which are specific nucleotide segments on conserved regions (18S rDNA region (NS1-NS2 primers))on SSU rDNA and on variable regions (internal transcribed spacer (ITS) regions (primer 2/primer 5 for ITS1 region and primer 3/primer 4 for ITS2 region)). NS1-NS2-amplified PCR fragments are 550 bp for C. sp., 550 bp for N. oculata and 600 bp for human. ITS1-amplified PCR fragments are 1, 2 and 4 bands for C. sp. (350 bp), N. oculata (400 and 450 bp) and human (300, 450, 500 and 580 bp), respectively, while ITS2-amplified PCR fragments are 1, 2 and 1 bands for C. sp. (430 bp), N. oculata (430 and 600 bp) and human (400 bp), respectively. By using human-specific primers (AmpFlSTR® Profilerä PCR Amplification Kit), only human can be identified in the sample containing C. sp., N. oculata and human DNA, whereas C. sp. and N. oculata can not be detected, indicating the prevention of algal interference in human-specific primer-PCR procedures via AmpFlSTR® Profilerä PCR Amplification Kit. Detection limits of C. sp. and N. oculata DNA were 50 and 10 pg, respectively. The results of present investigation show that algae can be distinguished from human by NS1-NS2-amplified PCR fragments but not between C. sp. and N. oculata, while C. sp., N. oculata and human can be distinguished by ITS1- or ITS2-amplified PCR fragments. Evidently, the specificity of DNA segments in marine microalgal and human DNA provides the base for investigation of cause of death in drowning case in the marine environment.

Forensic social work is a new field in South Africa. Forensic social work is regarded as a speciality, but has not been registered as such by the South African Council for Social Service Professions. There is a growing need to utilize experts in South African courts. Social workers are not trained to provide in this need. Social workers in private practice have recognized this need and equipped themselves to render this service to courts. The South African Police Service employs forensic social workers to assist the Child Protection Units. Despite this there was no formal training available in forensic social work, until recently. This study aims at investigating the availability of forensic training for social workers in order to develop guidelines for forensic training programmes. Universities agree that statutory social work forms part of the duty of every social worker and that training in this regard is needed. They also indicate that existing training does not prepare the social worker for effective services to the courts. It is clear that universities regard forensic social work as a specialised field and do not believe that under-graduate training is realistic. All participating institutions agree that a need exists for post-graduate forensic training. / Thesis (M.A. (MW))--North-West University, Potchefstroom Campus, 2008.

Within Canada’s federal correctional system, prison-hospitals provide both in-patient and ambulatory services to incarcerated male offenders. With at least 12% of incarcerated men being identified at intake as having a mental health disorder, the need for these services is significant (Sampson, Gascon, Glen, Louie & Rosenfeldt, 2007). While some description of the mental health services provided, internal operational reviews, and external health services accreditation surveys of these prison-hospitals are available, there has been very little attention paid to the challenge of trying to balance the dual correctional and mental health mandates of these facilities. Research in comparable facilities and services in the United States describe mental health care as a ‘non-system’ of care and state that mental health staff receive very little system-wide direction regarding the provision of services (Cruser & Diamond, 1996; Elliot, 1997). This is a study that critically analyses how mental health care has become subordinated to correctional and security priorities in a Canadian prison-hospital. Five key elements identified in the policy implementation literature are used to explicate the everyday experiences of frontline staff as they work to provide mental health services in this correctional environment. The thesis argues that the mental health work of frontline prison staff is subverted by a lack of vision for mental health care within organizational policy structures, allowing the detailed correctional policy structures to become the dominant force in implementation and decision making. Using the theory and method of institutional ethnography developed by sociologist Dorothy Smith, the analysis displays how the everyday activities of frontline staff are systematically organized by routine organizational policy structures to advance the correctional mandate of the prison-hospital while mental health care has slowly declined. The study finds that mental health care is socially organized as a ‘zero-sum game’. As policy texts have concerted and coordinated the everyday activities of frontline staff in predictable ways, gains for the correctional and security priorities of the prison-hospital have meant significant and repeated losses for mental health care. However, there are ‘windows of opportunity’ for frontline staff to advance the mental health mandate of the prison-hospital if they work together. / Thesis (Ph.D, Rehabilitation Science) -- Queen's University, 2010-04-28 14:46:36.212

Protecting privacy of individuals is critical for forensic genetics. In a kinship/identity testing, related DNA profiles between user's query and the DNA database need to be extracted. However, unrelated profiles cannot be revealed to each other. The challenge is today's DNA database usually contains millions of DNA profiles, which is too big to perform privacy-preserving query with current cryptosystem directly. In this thesis, we propose a scalable system to support privacy-preserving query in DNA Database. A two-phase strategy is designed: the first is a Short Tandem Repeat index tree for quick fetching candidate profiles from disk. It groups loci of DNA profiles by matching probability, so as to reduce I/O cost required to find a particular profile. The second is an Elliptic Curve Cryptosystem based privacy-preserving matching engine, which performs match between candidates and user's sample. In particular, a privacy-preserving DNA profile matching algorithm is designed, which achieves O(n) computing time and communication cost. Experimental results show that our system performs well at query latency, query hit rate, and communication cost. For a database of one billion profiles, it takes 80 seconds to return results to the user.

This project uses radionuclides from the uranium-238 decay chain series in conjunction with lead, strontium carbon and nitrogen stable isotope ratios to achieve accurate dating and geographical sourcing of human skeletal remains. A pilot study was conducted in order to test the hypothesis that 210pb stored within the skeleton during life decays at a known rate once death occurs. Samples of femur were used from 12 Portuguese individuals whose year of death was known.
