Comparison of modern techniques for saliva screening

Saliva stains present a unique challenge in the forensic setting, often challenging the analyst to weigh the value of presumptive indication of the fluid versus the potential for DNA analysis to yield identification information. There are many situations in which determining the presence of a body fluid is probative and further corroborates DNA evidence. That said, even a minute portion of sample consumed by a screening test could mean the difference between a full, partial, or null profile obtained through DNA analysis. The basis of presumptive testing or screening of saliva has historically been based on the presence of amylase, a component found in relatively high concentrations in human saliva versus other body fluids and substances. Though the current available methods for the screening of saliva in a forensic application have grown in number, the popularity of these methods seemingly has not. This study attempts to identify a specific and sensitive saliva screening test by comparing three modern techniques--the recently released SALIgAE, Phadebas, and starch-iodine mini-centrifuge test--on the basis of sensitivity, specificity, mixtures, and simulated casework samples while also considering sample consumption. The Phadebas method for presumptive saliva testing detected dilutions of neat saliva down to 1:200 versus considerably less sensitive results with SALIgAE and the starch-iodine mini-centrifuge test. Utilizing a screening test with a high degree of sensitivity, such as Phadebas, allows an analyst to gain a maximum amount of information in the form of body fluid indication and DNA results because of the consumption of a small portion of sample.     

The relationship between serial sexual murder and autoerotic asphyxiation

This case series documents and examines the association between autoerotic asphyxiation, sadomasochism, and serial sexual murderers. Autoerotic asphyxiation, along with other paraphilias found in this population, is reviewed. Five cases of serial sexual killers who engaged in autoerotic asphyxiation were identified worldwide: four from the United States and one from Russia. Case reports for each are provided. All (100%) were found to have sexual sadism in addition to autoerotic asphyxiation. Furthermore, two (40%) had bondage fetishism, and two (40%) had transvestic fetishism, consistent with these paraphilias co-occurring in those with autoerotic asphyxiation. Overall the group averaged 4.0 lifetime paraphilias. Some possible relationships were observed between the offenders' paraphilic orientation and their modus operandi, e.g., all of these serial killers strangled victims-suggesting an association between their sadistic and asphyxiative paraphilic interests. The overlap of seemingly polar opposite paraphilias in this sample--sexual sadism and autoerotic asphyxiation--is explored from a historical and clinical perspective. Multiple commonalities shared between these five offenders and serial sexual murderers in general are addressed. A primary limitation of this study is its small sample size and empirical basis; the results may not be generalizable beyond the sample. The findings from this study support the supposition that crime scene behaviors often reflect paraphilic disturbances in those who commit serial sexual homicides.     

Adolescent Self-Esteem and Gender: Exploring Relations to Sexual Harassment, Body Image, Media Influence, and Emotional Expression

Self-esteem plays a central role in mental health, yet not enough is known about how youth evaluate themselves as they move across adolescence. This study used a cross-sectional design to examine age and gender patterns in self-esteem and to explore how contemporary social influences relate to adolescent self-esteem. Self-reported influences on self-esteem involving the media, sexual harassment, body image, family and peer relationships, and emotional expression were evaluated with 93 boys and 116 girls in Grades 5, 8, and 12. Girls reported lower self-esteem than boys in early adolescence, and late adolescent boys reported lower self-esteem than younger boys. The predictors as a set accounted for a significant portion of the variance in self-esteem, while the best predictor of self-esteem varied by age and gender. Large gender differences were present for emotional expression, with boys becoming more restrictive across adolescence. Girls reported more negative body image and media influence scores than did boys in late childhood and early adolescence. Body image appeared to mediate the relationships between certain predictors and self-esteem for girls, while gender and grade appeared to moderate the relationship between media influence and self-esteem for girls and boys.     

Hero or Villain? Cinematic Lawyers and the Delivery of Justice

This essay is concerned with two specific issues that have as their backdrop the heroic central figure, the trial lawyer. First it considers the role of screen lawyers in seeking to maintain public (in this sense the public is the community within the film) support for the due process of law. The issue is the link between the lawyer and the initiation of the formal legal process. Essentially it is the extent to which the lawyer defends the institution of law. The second part of the piece considers when screen lawyers are permitted to go outside the formal process of law to ensure that the right result is achieved. It examines instances of where lawyers have been prepared to go 'beyond law' to achieve justice. Such acts raise a number of questions concerning how such behaviour affects perception of the legitimacy of the law, professional ethics, and the relationship between law and justice     

A China Divided since the Turnover of Political Power in Taiwan

Since March 2000 the turnover of political power in Taiwan to the Democratic Progressive Party (DPP) and President Chen Shui-bian has been associated with a bitter clash between two visions for Taiwan's future: a vision of Taiwanese nationalism promoted by President Chen and the DPP versus one of engagement with mainland China that aims to create a special relationship while engaging the Western world, as promoted by the KMT and some of its allies. These conflicting visions will continue to interact and influence political life in significant ways.     

The Local Government Review: An Inter-Organizational Perspective

This article uses Benson's 'political economy' model of inter-organizational relations to interpret inter-authority relationships during the course of the local government review process in England (1992-95) and in particular to explain the preparedness of large numbers of district councils to support proposals which implied their own destruction. Six more specific influences are identified which led to this outcome:
(i) The changing pattern of expectations and perceived possibilities as the Review progressed.
(ii) The conflictual context of relations within the network linking individual counties and districts, and their respective associations.
(iii) The influence of the districts' national representative body - the ADC - which was arguing strongly for a 'super-district' solution.
(iv) The plausibility of the view of some mergers as de facto takeovers of one authority by another.
(v) The special nature of local authorities as (party) political institutions as well as public sector bureaucracies.
(vi) The rationing of information through central-local networks, in the context of 'unclear rules'.
It is concluded that with certain modifications Benson's framework provides a helpful explanatory mechanism.
