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.     

Effects of Hurricane Katrina and Other Adverse Life Events on Adolescent Female Offenders: A Test of General Strain Theory

This study tested Agnew's General Strain Theory (GST) by examining the roles of anger, anxiety, and maladaptive coping in mediating the relationship between strain and three outcomes (serious delinquency, minor delinquency, and continued involvement in the juvenile justice system) among adolescent female offenders (N = 261). Strains consisted of adverse life events and exposure to Hurricane Katrina. Greater exposure to Hurricane Katrina was directly related to serious delinquency and maladaptive coping. Hurricane Katrina also had an indirect effect on minor delinquency and Post-Katrina juvenile justice involvement mediated through maladaptive coping. Adverse life events were associated with increased anger, anxiety, and maladaptive coping. Anger mediated the relationship between adverse life events and serious delinquency. Anxiety mediated the relationship between adverse life events and minor delinquency. Maladaptive coping strategies were associated with minor delinquency and juvenile justice involvement. Findings lend support to GST.     

Parenting without Protection: How Legal Status Ambiguity Affects Lesbian and Gay Parenthood

Through the lens of lesbian and gay parenthood we ask how individuals who experience “legal status ambiguity”—that which emerges when legal fluctuations combine with divided attitudes, ignorance of the law, and autonomous institutional gatekeepers—exercise their legal rights and responsibilities. The results from thirty‐one interviews with lesbian and gay parents in Oregon and their six adult children suggest that the state's fluctuating legal and social climates for lesbian and gay parenting between 1985 and 2013 presented significant challenges for two generations of same‐sex parents. Although both cohorts created and utilized a range of legal and social mechanisms to assert their legal rights, they found these rights to be controlled as much by gatekeeper perspectives as by legal force. After the 2015 Obergefell ruling on marriage equality, lesbian and gay parenting status remains a site of ongoing legal and social contestation, providing insight into the risks and challenges of legal status ambiguity.     

Killing the messenger: Environmental reporters under fire in the Philippines

Abstract

In much of the world, reporting on the environment is like reporting on motherhood. It cuts across all political, economic, and social lines, and it's a safe beat. This is not true in the Philippines, where being an environmental reporter means taking on the richest and most powerful forces in the country. It can be, as one reporter put it, “bad for your health.” More to the point, in the Philippines environmental reporting is a life-and-death issue.     

Private finance for social housing in Australia

Abstract

A significant change in the finance of social housing in the 1980s was a movement to transfer responsibility for funding to the private sector. This article argues that governments must continue to be involved in social housing finance as this movement progresses. Financing initiatives undertaken in Australia are used to signal the risks associated with the provision of social housing finance, to illustrate the mechanisms employed to manage these risks, and to highlight the conflicts that arise when a mix of public and private funding is attempted.

The article proposes the introduction of “equity bonds” as an innovative way to raise funds for social housing and to overcome inefficiencies arising from the present complex and costly administrative structures. However, a commitment to ongoing subsidies to close the full rental gap is necessary for equity bonds to serve those most in need.     

Press Secretaries,Journalists, and Editors: Shaping Local Congressional News Coverage

The news media plays a key role in American democracy, often serving as the primary means by which voters learn about their elected representatives. However, the news media varies in its coverage of representatives, presenting voters with more frequent and favorable information about some House members than others, which may in turn influence voters' decisions at the polls. Although many scholars have examined the determinants of congressional news coverage, few have focused on the role of the actors who perhaps exert the most direct effect on such coverage: congressional press secretaries, journalists, and editors. In this study, I explore the influence of these actors on the tone and frequency of local congressional news coverage. I rely on data from two sources: (a) a content analysis of newspaper coverage of 100 representatives during the month prior to the 2006 election and (b) in-depth interviews with 51 congressional press secretaries and 22 journalists. These sets of data illustrate the important roles of both newspaper staff and congressional press secretaries in shaping the coverage House members receive. I conclude by discussing the implications of the findings for U.S. representatives and their constituents.     

A Detailed Cost Evaluation of a Juvenile Drug Court that Follows the Juvenile Drug Court Model (16 Strategies)

Although juvenile drug courts (JDCs) have now been in operation for 17 years, there is still no definitive appraisal as to this model's cost effectiveness and in particular, no detailed cost analysis of a JDC program following the 16 strategies until this one. The cost data presented in this paper build on the process and outcome evaluations performed on the Clackamas County Juvenile Drug Court (CCJDC). The criminal justice costs incurred by participants in drug court are compared with the costs incurred by eligible non‐participants. CCJDC participants had far more positive outcomes than those who did not participate in the program. In the two years after drug court entry, CCJDC participants cost the taxpayers $961 less per participant than similar individuals who did not attend the drug court program.
