Parent-adolescent conflict and stress as a parent: Are there differences between being a mother or a father?

Parent-adolescent conflict is viewed as a common dimension of the family during the teenage years. The purpose of the present study was to determine whether mothers and fathers of young adolescents differ in their report of conflict with their adolescent, level of stress, and parenting competence. Furthermore, the role of age and gender of the young adolescents was examined. One hundred and twenty-two adolescents and their parents participated in the study. All families were intact. The families were divided into groups according to the adolescent's age and gender. Analyses of variance with three factors (adolescent's age, adolescent's gender, mothers versus fathers) were performed. Mothers and fathers did not differ on personal (depression) or marital adjustment and on perceived parenting competency. In contrast, in terms of parent-adolescent conflict, mothers reported a less positive relationship, a greater number of conflicts, and more intense discussions of conflicts with their adolescents. Gender and age of the adolescent were not important contributors to the analyses. The results suggest that, in terms of the variables examined in this study, conflict in the parent-adolescent relationship is the primary difference between mothers and fathers.     

A quantitative comparison of smokeless measurements

Measurements of the type and concentration of propellant and stabilizer additives in smokeless gunpowder are used by forensic scientists investigating the source of explosives and by military laboratories assuring the safety and efficacy of munitions. The National Institute of Standards and Technology recently assessed the state-of-the-practice of smokeless powder measurements through an international measurement comparison exercise. We here present results provided by the five participants (of 20 total) reporting quantitative as well as qualitative values for two handgun reloading powders. All five of these participants reported values for nitroglycerin (NG), ethyl centralite (EC), diphenylamine (DPA), and N-nitrosodiphenylamine (NnDPA). Several participants additionally reported the concentrations of secondary stabilizer decomposition products. The unstable NG propellant additive appears to be more susceptible to method-specific calibration biases then are the stabilizer additives. All results from one participant were strongly biased relative to those of the other four. The within-participant measurement uncertainties for all analytes were self-reported to be 1 to 5% relative; among the four concordant participants, the measurement ranges are 5 to 10% relative. There was little consistency among the participants as to what components of measurement variance were included in their uncertainty statements. A discussion of the certainties in these measurements and factors that affect the accuracy of gunpowder additive determinations is presented.     

The Effect of pH on Electrolyte Detection of Fingermarks on Cartridge Cases and Subsequent Microscopic Examination

Cartridge cases may contain deposited fingermarks when the firearm was loaded ( http://www.nij.gov/pubs-sum/225320.htm , J Forensic Sci, 53 , 2008 and 812). Cartridge cases can be individualized with microscopic examination. However, heat and friction degrades the deposited fingermark on the fired cartridge cases, if any on the surface. Also, unfired and fired cartridge cases are made of metal, which is a nonporous surface that does not retain fingermarks well ( http://www.nij.gov/pubs-sum/225320.htm ). This study tests the effects of pH level on fingermark clarity on brass fired and unfired cartridge cases and microscopic striation examination (MSE). Two trials were performed to determine the optimal pH in fingermark clarity for both types of cartridges. This was performed through immersion in six pH range solutions from dilutions of sulfuric acid and sodium hydroxide for 24 h for the purpose of enhancing the fingermarks on the metal. The use of the optimal neutral pH level is suggested because immersion of the cartridge cases in pH 1–3 and 3–5 affects MSE.     

Development of a Computer‐Assisted Forensic Radiographic Identification Method Using the Lateral Cervical and Lumbar Spine

Medical examiners and coroners (ME/C) in the United States hold statutory responsibility to identify deceased individuals who fall under their jurisdiction. The computer‐assisted decedent identification (CADI) project was designed to modify software used in diagnosis and treatment of spinal injuries into a mathematically validated tool for ME/C identification of fleshed decedents. CADI software analyzes the shapes of targeted vertebral bodies imaged in an array of standard radiographs and quantifies the likelihood that any two of the radiographs contain matching vertebral bodies. Six validation tests measured the repeatability, reliability, and sensitivity of the method, and the effects of age, sex, and number of radiographs in array composition. CADI returned a 92–100% success rate in identifying the true matching pair of vertebrae within arrays of five to 30 radiographs. Further development of CADI is expected to produce a novel identification method for use in ME/C offices that is reliable, timely, and cost‐effective.     

American murder mystery revisited: do housing voucher households cause crime?

This paper reviews the current state of the housing market, particularly in the shadow of the foreclosure crisis, the collapse of the financial system, and persistent unemployment. The authors outline the policy priorities necessary to facilitate the recovery of the housing market in general and to encourage comprehensive revitalization of the hardest hit communities.     

Ripple effects: the groundnut scheme failure and railway planning for colonial development in Tanganyika, 1947–1952

While the reasons for the failure of the groundnut scheme are well understood, its effects on colonial development in Tanganyika are not. Drawing from the voluminous paper trail that development planning leaves in its wake, this paper traces the effects of the groundnut scheme demise on a contemporaneous plan to build a railway across Tanganyika to the Northern Rhodesian copperbelt. Tensions arose among the railway planners – civil servants, politicians, and consultants from Britain, Africa, and the United States – when, midway through the planning process, the scale of the groundnut scheme collapse became public. I demonstrate how this revealing crisis prompted planners to eschew the project's production-oriented impetus and embrace a welfare-oriented conclusion. By demonstrating the interlinked nature of development projects, this paper proposes a new angle for studying the history of development in an era characterised by the rapid proliferation of projects.     

Civil Servants on the Silver Screen: The Depiction of Government in American and Australian Cinema

With the prevalence of government, it is unsurprising to find it frequently represented on the silver screen. But, with the ability of film to influence perceptions and attitudes, questions arise, including: how is government portrayed on the silver screen? Are government bureaucrats berated or praised? This research examines the representation of government—and civil servants in particular—in a comparative setting. The top 100 box office grossing films of all time in the United States and Australia were selected to address the question: how do these films in the United States and Australia depict government? This study analyzes these 200 films and the more than 400 government characters in these films and suggests that government in both American and Australian films does not fare well. However, despite the generally negative—or at best mixed—depictions of government overall, individual government characters fare better.     

Substance Use Among African American Adolescents in the Midwest

The purpose of this article is to examine the attitudes and substance use behaviors of African American adolescents living in the Midwest. A baseline survey was administered to 463 African American teens between the ages of 11–19. The article examines the relationship between attitudes toward drugs and drug-using behavior in this African American sample. Drug use will be compared to national drug use norms established by the Youth Risk Behavior Surveillance Survey. Overall participants had fairly negative attitudes toward drugs. Sixty percent of the sample reported that they were committed to a drug-free life, 74% had made a decision to stay away from marijuana, 79% reported making a decision not to smoke cigarettes, and 71% reported they would not get drunk in the next year. Females were more likely to stay away from marijuana than males. In this current study there is cause for alarm; participants reported higher percentages of ever smoking cigarettes and marijuana than the Youth Risk Behavior Surveillance Survey. This study shows there is a need to provide substance abuse prevention programs for African American adolescents. Limitations and future directions are also discussed.     

Culture,Institutions and Campaign Effects: Explaining the Outcome of Malta's EU Accession Referendum

This survey examines the background to and the campaign preceding Malta's EU accession referendum. The result of the referendum, which was held on 8 March 2003, and which was the first of the EU accession referendums of 2003, was a 53.65% vote in support of membership, on a turnout of close to 91%. Explaining both the relatively low support for EU accession and the high turnout on referendum day involves weighing up the relative impact of distinctive features of Malta's political culture and institutional framework against more immediate campaign effects. While the conclusion is that the high turnout in the Maltese EU accession referendum can be traced to Malta's political culture, the relatively low but positive vote in favour of membership can only be fully understood by focusing on a range of factors, including campaign-related factors, such as the credibility of the arguments presented by the ‘yes’ and ‘no’ camps and the balance of resources available. The most important factor explaining the result of the Maltese referendum are, however, the cues provided by the political parties prior to and over the course of the referendum campaign.
