The relationship between life satisfaction, risk-taking behaviors, and youth violence

This study builds on existing criminological theories and examines the role of life satisfaction and self-control in explaining youth violence. Using data from a stratified cluster sample of 5,414 public high school students who responded to the South Carolina Youth Risk Behavior Survey, the study examines the relationship between adolescents'perceptions of life satisfaction, behavioral risky acts, and self-reported acts of violence. Analyses indicate that higher levels of life satisfaction are associated with lower violence. Participation in work and involvement in health-related risk-taking behaviors pertaining to sex, drugs, and alcohol are also associated with increased violence. The implications of these findings for criminological theory and for school-based violence prevention programs are discussed.     

Prior Experiences as Temporal Frames of Reference in Social Justice: The Influence of Previous Fairness Experiences on Reactions to New and Old Supervisors

This paper focuses on the psychology of social change and social justice. Specifically, we focus on subordinates’ reactions to new and old supervisors, and we argue that in evaluating these different types of supervisors, subordinates may rely on prior fair or unfair experiences as temporal frames of reference. We further propose that a result of these frames of reference may be that previous fairness experiences have a bigger impact on subordinates’ reactions to subsequent neutral communications when an old rather than when a new supervisor is the source of that communication. Findings of two empirical studies indeed show that subordinates who had had fair experiences with a particular supervisor reacted more positively toward subsequent neutral messages when the communication was coming from the old supervisor rather than from the new supervisor. Subordinates who had had unfair experiences, however, reacted more negatively toward the communication when the source was the old rather than the new supervisor. Some evidence was also found for contrast effects such that people who react to a new supervisor may react more positively with the neutral demand from this authority figure when they have earlier experienced unfair as opposed to fair treatment by a different supervisory agent. These findings were obtained on subordinates’ satisfaction with the supervisors’ communication and their acceptance of the supervisor. Finally, we discuss the implications for the psychology of social change and social justice.     

Using spectral information in forensic imaging

Improved detection of forensic evidence by combining narrow band photographic images taken at a range of wavelengths is dependent on the substance of interest having a significantly different spectrum from the underlying substrate. While some natural substances such as blood have distinctive spectral features which are readily distinguished from common colorants, this is not true for visualization agents commonly used in forensic science. We now show that it is possible to select reagents with narrow spectral features that lead to increased visibility using digital cameras and computer image enhancement programs even if their coloration is much less intense to the unaided eye than traditional reagents. The concept is illustrated by visualising latent fingermarks on paper with the zinc complex of Ruhemann's Purple, cyanoacrylate-fumed fingerprints with Eu(tta)(3)(phen), and soil prints with 2,6-bis(benzimidazol-2-yl)-4-[4'-(dimethylamino)phenyl]pyridine [BBIDMAPP]. In each case background correction is performed at one or two wavelengths bracketing the narrow absorption or emission band of these compounds. However, compounds with sharp spectral features would also lead to improved detection using more advanced algorithms such as principal component analysis.     

The High Court and Australian Federalism

This article analyzes the constitutional role of the High Courtof Australia during its first hundred years and the effect ofthat role on the Australian federation. The High Court has acceptedas axiomatic that part of its function is the judicial reviewof legislation of both the federal and state legislatures. Itsapproach is relatively modest and "textualist." That approachhas been affected by historical changes, including Australia'sindependence from Great Britain. The decisions of the High Courthave provided a framework for the development of the Australianfederation over the last century in increasing the relativeimportance of the federal government at the cost of the stategovernments. However, those decisions are probably best viewedas reflecting, rather than creating, the changes and developmentsin the federation.     

A functional approach to sudden unexplained infant deaths

There is a great deal of variation in the methods and wording used by medical examiners in the medicolegal investigation and certification of infant deaths. This paper was created by the NAME Ad Hoc Committee on Sudden Unexplained Infant Death to address several specific issues, namely: * To establish a functional approach to the investigation of sudden unexplained infant deaths; * To outline a "bare minimum" set of recommendations to define the scope of investigation required; * To recommend methods and wording to be used when certifying infant deaths; * To develop a list of potential stressors or possible external causes of death that should be identified and reported on the death certificate and/or within a medical examiner/coroner office database. This paper was electronically posted for NAME member review and comment for a period of 30 days. The paper was further revised based on member comments and then submitted to the NAME board of directors in the fall of 2005 prior to the annual meeting. This text of this paper was officially approved and endorsed by the NAME board of directors on October 14, 2005, at the annual meeting in Los Angeles, CA.     

Population data from sub-populations of the Northern Territory of Australia for 15 autosomal short tandem repeat (STR) loci

It is a requirement that forensic DNA profiling evidence be accompanied by an estimation of its weight, in order that the court can assign an appropriate probative value to the evidence during legal proceedings. There are various models by which this estimation can be made, but each relies on approximations of the allele frequencies in the relevant population. It is also important to assess relevant population genetic features of the available data. This report provides allele frequencies and estimates of common population genetic parameters for the major sub-populations of the Northern Territory of Australia genotyped at 15 autosomal short tandem repeat (STR) loci.     

The Indiana Toll Road Lease as an Intergenerational Cash Transfer

In a recent incarnation of the public–private partnership, state or city governments agree to lease revenue‐producing assets to a private operator for a lengthy period, up to 99 years. The government receives an up‐front payment, allowing it to collect many years of future revenue at once. This article evaluates the distributional consequences across time of one asset lease, the Indiana Toll Road. The analysis finds that the majority of benefits, in the form of road construction, are enjoyed in the early part of the lease, while the bulk of the costs fall late in the lease, raising important questions about intergenerational fairness.
