Amphetamines in washed hair of demonstrated users and workplace subjects

Cardiovascular complications of cocaine abuse include myocardial ischemia and infarction, dysrhythmias, cardiomyopathies and aortic dissection. The case in point pertains to a 26-year-old, Caucasian male, substance abuser who suffered a thoracic aortic dissection following the use of crack cocaine. The autopsy and histological findings showed a connective tissue abnormality including a focal microcystic medial necrosis and a fragmentation of the elastic fibers in the arterial walls. Blood concentrations of cocaine and benzoylecgonine, taken individually, were considered to be within a potentially toxic range. Blood concentrations of methadone also indicated use of this drug at the same time. The small amounts of morphine found in the blood and urine were compatible with heroine or morphine use more than 24 h before death.     

Incapacitation and fires

Traditionally quoted levels of the products of combustion are too high to account for all the problems of incapacitation and death in fires. Because people may not die instantly in a fire, they can continue to inhale toxic gases after collapse. Collapse may occur very quickly. Experience drawn from analysing the effects of the Manchester Boeing 737 accident and a building fire are used to debate this issue.     

Municipal Bond Issuance: Is There Evidence of a Principal-Agent Problem?

Is there evidence of a principal-agent problem in the municipal bond industry? Do public managers, either on their own or through private sector agents, act to increase their own utility at the expense of the public? This article examines municipal bond decisions in the context of principal-agent theory based on data collected through a random sample survey of municipal bond issuers. Principal-agent theory is not well developed in the public sector. In the municipal bond industry, however, we have evidence that it helps explain the actions of public managers and elected officials, in particular for pay to play and the importance of interest rates vis-à-vis relationships. These actions carry potential costs to citizens.     

Menarcheal status and parent-child relations in families of seventh-grade girls

The associations between menarcheal status and several child-rearing and outcome variables were examined for mother-daughter and father-daughter dyads. All variables were assessed with questionnaires as an extension of earlier observational studies. Analyses were conducted via multiple regression analyses wherein menarcheal status was treated as a continuous variable and was entered into the regression equation as a set of power polynomial terms. The results indicated that most of the significant relations occurred for the mother-daughter dyad, and most of these relations were curvilinear. When menarche occurs at or around the modal time, changes in parent-child relations may be best thought of as temporary perturbations, but when menarche occurs early the effects may persist.The research reported here was funded by Father Flanagan's Boys Home, Inc., and by a grant to the senior author from the John D. and Catherine T.

On the Meaning of Survey Reports of Roll‐Call “Votes”

Contemporary efforts to evaluate representation often compare survey measures of how citizens say they would vote on legislation to what elected officials do in office. These comparisons generally suggest poor representation. We argue here that this common design is unlikely to effectively evaluate representation because responses to survey questions differ in important aspects from voting in legislatures. Measurement error and construct validity undermine the comparison. Three survey experiments show that providing partisan and nonpartisan information readily available to legislators materially changes respondents' expressed preferences on roll‐call votes. With information, expressed policy positions are both less centrist and more closely matched to legislator behavior in their preferred party. Respondents also appear aware of their own lack of knowledge in evaluating roll‐call policy votes. The treatment effect of information decreases in confidence judging policy in that area. We show similar patterns for respondent opinions on Supreme Court decisions.     

The single most polymorphic STR Locus: SE33 performance in U.S. populations

The STR locus SE33 (ACTBP2) located on chromosome 6 (6q14) is arguably the most polymorphic marker examined thus far by the forensic community with a heterozygosity of >0.95 in some populations. Three different primer sets were utilized in this study in order to assess the possibilities of primer binding site mutations. Population variation was measured in 460 U.S. Caucasian, 445 African American, 336 Hispanic, and 202 Asian samples along with mutation rates from almost 400 father–son pairs. In addition, the 10 genomic DNA components in NIST Standard Reference Material SRM 2391b were sequenced and found to exhibit a variety of additional base changes, insertions, and deletions outside of the SE33 repeat region.     

An Investigation of Biographical Information as a Predictor of Employment Termination among Law Enforcement Officers

An important service that police psychology can offer law enforcement administrators is assistance in the selection of future officers. Police psychologists have traditionally focused on the identification of psychopathology and exclusion of applicants who were found to be mentally ill. The introduction of the Americans with Disabilities Act (1990) has changed what had been considered appropriate exclusion criteria because of the introduction of increased civil rights protections for persons with disabilities. At the same time, increasing civil liability for law enforcement departments in regard to officer misconduct has compelled police psychologist to evaluate potential for future misconduct by non-clinical means. The scientific examination of biographical data may be one method of establishing the relationship between officer candidate variables and future misconduct. This paper examined the predictive validity of biographical information for a sample of 2965 police officer candidates. Results indicated that several biographical variables were significantly correlated with later termination. However, results of regression analyses indicated that biographical variables alone accounted for limited variance in the prediction of police officer termination. The use of biographical information as a sole determinant of police candidate suitability was not supported and the use of additional sources of data would be required for effectual forecasting purposes.     

Expensive English: an accessible language approach for Papua New Guinea agricultural development

Language used in capacity development programmes is usually that of the donor country, often English. However, research shows that the language used can be detrimental to the success of the programme. Little attention has been given to the issue of language, yet it is important that programme participants fully understand the capacity development programme’s concepts to ensure that the programme achieves its full potential. This article explores an accessible language approach to a Papua New Guinea development programme. Arguments are based on an in-country research project designed to provide women and men with deeper understanding of gender equity.     

Modeling Temperature Variations Using Monte Carlo Simulation: Implications for Estimation of the Postmortem Interval Based on Insect Development Times*†

The association between insect development and temperature is well established. Thermal summation using accumulated degree-day measures is commonly used. However, the time at which evidence is collected is important in these estimates. The aim of this study was to provide a simulated model of the effect of temperatures on six dipteran species commonly associated with cadavers, from the death scene to the refrigerator, and finally at the time of autopsy. Temperatures measurements were sampled over a 16-month period from the external environment (external to the mortuary), within the mortuary refrigerator, and within the mortuary autopsy suite. Monte Carlo simulation using accumulated degree-days (ADD) was used to estimate the variations based on the mean and standard deviation of the temperature measurements. It was found that there was a negative correlation between the base temperature of the fly species (lowest temperature at which the flies will survive) and developmental likelihood. Species with high base temperatures (Chrysomya albiceps, Chrysomya chloropyga, and Musca domestica) were less likely to continue development in refrigerators than species with lower base temperatures (Lucilia sericata and Piophila casei). The findings of this study highlight the importance of recording temperature measurements and the period of refrigeration on PMI estimation especially when continued development occurs in spite of a period of cooling of the insect evidence.
