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.     

The free rider problem: Experimental evidence

This paper addresses the need to learn more about the relative desirability of the current FASB and its alternatives. It responds to this need by demonstrating how a given standards-setting alternative might be preliminarily analyzed in terms of its feasibility and the degree to which its theoretical objectives are operationally attainable. The analysis emphasizes that it is not the existence of possible operational shortcomings that is important, but how its operational properties compare with those of other available alternatives. The analysis itself reveals that, in spite of operational shortcomings, standards-setting by means of a demand-revealing process may be an alternative worthy of further consideration both in its own right, and as a basis of comparison for assessing the relative strengths and limitations of the current FASB.     

Characteristics of assaultive patients with schizophrenia versus personality disorder: six year analysis of the Assaulted Staff Action Program (ASAP)

Literature reviews of individual assaultive patients, repetitively violent patients, and restrained assaultive patients document that persons diagnosed with schizophrenia or personality disorder are at the highest risk to become assaultive. While there has been some initial research of possible predictor variables across diagnostic groups, this six-year retrospective study is the first to compare only persons with schizophrenia or personality disorder on basic demographic and the selected clinical variables of history of violence, personal victimization, and substance use disorder. In this study, the variance suggested that persons with schizophrenia and personality disorder were both likely to be assaultive. Assaults by persons with schizophrenia were somewhat proportional to their presence in the population studied. However, personality disordered patients represented a disproportional increase from the population studied. Younger females with a diagnosis of personality disorder and with histories of violence toward others and personal victimization appeared at increased risk to be assaultive and to require restraints. The findings and their implications for safety and clinical care are discussed.     

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.     

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.     

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.     

Antisocial Personality Disorder and Physical Partner Violence Among Single and Dual Substance-Abusing Couples

The current study examined how antisocial personality disorder (APD) and substance use disorder contributed to partners’ reports of physical partner violence among single and dual substance-abusing couples. Participants were 69 heterosexual couples entering treatment in which one or both partners met criteria for substance use disorder. APD diagnosis of the male partner was linked to significantly higher male-to-female and female-to-male perpetration of physical partner violence and victimization. Female partner’s APD diagnosis was associated with women’s reports of victimization by their male partners. Dual substance use diagnosis emerged as a moderator, in which the effect of men’s APD diagnosis on men’s perpetration of physical partner violence and victimization was significantly reduced if both partners had substance use disorder. Findings underscore the importance of both partners’ APD diagnosis and substance use status for understanding physical partner violence among single and dual substance-abusing couples.     

Does Strategic Planning Improve Organizational Performance? A Meta‐Analysis

Strategic planning is a widely adopted management approach in contemporary organizations. Underlying its popularity is the assumption that it is a successful practice in public and private organizations that has positive consequences for organizational performance. Nonetheless, strategic planning has been criticized for being overly rational and for inhibiting strategic thinking. This article undertakes a meta‐analysis of 87 correlations from 31 empirical studies and asks, Does strategic planning improve organizational performance? A random‐effects meta‐analysis reveals that strategic planning has a positive, moderate, and significant impact on organizational performance. Meta‐regression analysis suggests that the positive impact of strategic planning on organizational performance is strongest when performance is measured as effectiveness and when strategic planning is measured as formal strategic planning. This impact holds across sectors (private and public) and countries (U.S. and non‐U.S. contexts). Implications for public administration theory, research, and practice are discussed in the conclusion.
