Comparison of motor oils using high-temperature gas chromatography-mass spectrometry

The analysis of motor oils has wide applications in the forensic science field from comparing lubricants transferred between an automobile and a victim or crime scene to differentiating the compositions of plastic explosives. In this study, 40 unused motor oils were analyzed and compared by high-temperature gas chromatography-mass spectrometry to determine the potential for oil individualization. Oil samples were also collected from the crankcase dipsticks of 30 cars. Twenty-six of these oils could be differentiated from each other based on visual comparisons of the unresolved envelope (baseline rise due to incomplete separation) and the resolved hydrocarbons in the raw total ion chromatograms (TICs) and smoothed TIC data. Four of these oils were analyzed as unknowns and were correctly related to the corresponding vehicle. The use of extracted ion profiles (EIPs) was explored as a means to further discriminate between the indistinct samples based on the polycyclic aromatic hydrocarbon (PAH) content. The research discussed in this paper demonstrated that differentiation of motor oils was possible by examining the TIC, smoothed TIC, and EIP data.     

Exploring the utility of entitlement in understanding sexual aggression

Purpose

Sexual aggression on college campuses has received a great deal of research attention. Little criminological theory, however, has systematically linked individual-level risk factors for sexual aggression with broader societal factors like patriarchy. DeKeseredy and Schwartz (1993) proposed that societal patriarchy is translated into individual attitudes of male sexual proprietariness and entitlement, which provide motivation and justifications for sexual violence.

Methods

This study explored the concept of entitlement through various measures and demonstrated the utility of the concept by linking it with other theoretically-relevant variables, including self-control, sexual partners, use of pornography, adversarial sexual beliefs, and rape myth adherence.

Results

Entitlement was significantly correlated with theoretically-relevant variables in the expected directions. Additionally, entitlement was able to distinguish sexually aggressive and nonaggressive men. Multivariate models provided support for the theoretical assertion that entitlement fosters rape-supportive attitudes and behaviors, which in turn was related to sexual aggression.

Conclusions

Entitlement is an important concept in understanding sexual aggression, and the causal relationships implied by theory should be explored further in future research. Implications and directions for future research and theory are discussed.     

Treatment of Concurrent Substance Dependence,Child Neglect and Domestic Violence: A Single Case Examination Involving Family Behavior Therapy

Although child neglect and substance abuse co-occur in greater than 60% of child protective service cases, intervention outcome studies are deplorably lacking. Therefore, a home-based Family Behavior Therapy is described in the treatment of a woman evidencing child neglect, substance dependence, domestic violence and other co-occurring problems. Treatment included contingency management, self control, stimulus control, communication and child management skills training exercises, and financial management components. Results indicated improvements in child abuse potential, home hazards, domestic violence, and drug use, which were substantiated by objective urinalysis testing, and tours of her home. Validity checks indicated the participant was being truthful in her responses to standardized questionnaires, and assessors were “blind” to study intent. Limitations (i.e., lack of experimental control and follow-up data collection) of this case example are discussed in light of these results.     

The "last vestiges of life"

On 4 June 2010, Deputy State Coroner Schapel of the Coroner's Court of South Australia ruled that he had jurisdiction to conduct an inquest into the death of Tate Spencer-Koch, who was declared deceased following complications during her home-birth. Coroner Schapel considered he had jurisdiction on the basis that Tate was a "person in the eyes of the law" under the born alive rule, as she had completely left her mother's body and she could be shown to have been alive after birth, evident from the PEA detected in her heart 10 minutes following her delivery. Close consideration of this ruling, however, reveals issues with the application of the born alive rule in the case.     

Comparing social,emotional, and behavioral health risks among youth attending public versus parochial schools

Parochial schools are assumed to provide better social and academic experiences; however, few studies account for selection bias when comparing with public schools. This study contrasted public versus parochial schools using propensity score matching across a range of outcomes (e.g., perceptions of school, emotional symptoms, substance use, bullying). Using a sample of 58 public and 5 parochial high schools, the nonmatched analyses suggested a significant advantage for parochial schools students (e.g., better on 23 of 32 indicators). However, the propensity score matched analyses revealed nine differences (e.g., weapon carrying, smoking), two of which (i.e., stress and cyberbullying) favored public schools. While at first glance parochial schools generally appear to be healthier and safer learning environments, accounting for selection bias, the gap was narrowed. Students in parochial schools may struggle with issues related to social, emotional, and behavioral health risk, and thus prevention programs should also be implemented in these settings.     

Examining the demographic profile and attitudes of citizens,in areas where organized crime groups proliferate

Whilst studies refer to the community impact of Organized Crime (OC), no survey currently exists to examine the views of those citizens who reside in areas where Organized Crime Groups (OCGs) proliferate. 431 questionnaires from households co-existing in high density OCGs areas were analysed in relation to: a) demographic information; b) views on the community and the police; and c) how they expected other residents to react to illegal incidents. Overall respondents thought the average citizen would refuse to intervene in 10% - 48% of illegal incidents, with the specific case influencing whether and how they would respond. The analysis then compared three communities who lived in high density OCG areas with a control community (n?=?343). The ‘OCG’ communities were more likely to report low collective efficacy and were generally least likely to expect their neighbours to confront a crime in action. Conversely, whilst the control group showed higher levels of collective efficacy and expected the average resident to be more likely in confronting illegal behaviour, this trend did not extend to street drug dealing and serious crime associated with OC. The study discusses the unreported intimidation associated with OCGs and the challenges of policing hostile environments.     

Performance Reporting: Assessing the Annual Reports of Malaysian Local Authorities

There have been calls for Malaysian local authorities to be more transparent and accountable in the discharge of their functional responsibilities. This study empirically evaluates the extent and quality of current performance reporting by local authorities. The disclosure of relevant information for discharging accountability obligations, as defined by a broad range of stakeholders, falls short of best practice. Therefore, the performance of Malaysian local authorities lacks transparency. The findings could assist in the development of more comprehensive guidelines for local authority reporting and raise awareness of information stakeholders expect to be reported in the context of accountability.     

The impact of interpersonal style on aggression and treatment non-completion in patients with personality disorder admitted to a medium secure psychiatric unit

Abstract

The aim of this study was to examine the impact of interpersonal style and psychopathy on treatment non-completion and aggressive behaviour. Participants were patients with personality disorder admitted for treatment to a structured group program operating within a medium secure psychiatric hospital. Assessment of personality disorder and psychopathy occurred prior to admission. Interpersonal style was assessed on admission with the Impact Message Inventory (IMI), a self-report transactional inventory. Files were subsequently reviewed to determine whether patients were aggressive during their hospital stay and whether they were prematurely expelled from the unit and therefore did not complete treatment. Results showed that patients who completed treatment were more nurturing and help-seeking. Aggressive patients were more competitive and dominant. Psychopathy did not differentiate treatment completers from non-completers or aggressive from non-aggressive patients. Clinical implications and opportunities for further research are explored.     

Criminal attitudes and psychopathic personality attributes of youth gang offenders in Singapore

Gang-affiliated youth are responsible for a disproportionate amount of serious and violent offenses. However, there is scant focus on the psychological variables that could be important for treatment planning and program development. Awareness of these variables is important for treatment planning and program development and also, potentially, for understanding which youth may be attracted to gangs. This study compared the criminal attitudes and psychopathic personality attributes of gang- and nongang-affiliated youth offenders (N=168) residing in youth correctional institutions in Singapore. Multivariate analyses indicated that favorable attitudes toward gangs (ATG), violence, and criminal associates remained significantly associated with gang membership after accounting for favorable attitudes toward violence and criminal associates, as well as increased attitudes of entitlement and impulsive/irresponsible traits. These attitudes were likely to perpetuate gang affiliation and criminal behavior, and thus should be a focus for intervention and rehabilitation efforts.
