The referral decision scale with mentally disordered inmates

Correctional facilities are increasingly burdened with mentally disordered offenders and are faced with the formidable task of effectively screening inmates for major mental disorders and suicide potential. Teplin and Swartz (1989) developed the Referral Decision Scale (RDS) as a rapid screen for schizophrenia and major mood disorders in jail populations. However, more recent research by Hart, Roesch, Corrado, and Cox (1993) has called into question the effectiveness of the RDS. In this study, we examined the convergent and discriminant validity of the RDS with the Schedule of Affective Disorders and Schizophrenia—Change Version (SADS-C) and the Personality Assessment Inventory (PAI) on a sample of 108 mentally disordered inmates. The RDS provided moderate evidence of convergent validity but failed to demonstrate acceptable discriminant validity, because of high intercorrelations on RDS subscales (heterotrait-monomethod coefficients). In comparison, the SADS-C yielded similar evidence of convergent validity and excellent discriminant validity.The authors would like to thank the Research Opportunities Program, University of North Texas for its grant support and Captain James Moore for his active cooperation.Tarrant County Mental Health and Mental Retardation Services.     

Dynamic Success on YouTube: A Longitudinal Analysis of Click Counts and Contents of Political Candidate Clips during the 2009 German National Election

Since the 2008 Obama victory, mass media and academic research have contributed to the widespread notion that modern political campaigns are won in the so-called ‘web 2.0’, more precisely on YouTube. While respective studies were able to identify some major factors for the success of political YouTube videos, some videos ‘failed’ to have the presumed success online. This lack of clarity has not been convincingly explained by cross-sectional designs without taking into account the dynamic aspects of the success of YouTube videos. This study evaluates and validates the impact of presentation, professionalism, topic, age and the typical slope of the website-visits over time on the total amount of page visits. Political YouTube videos were analysed over a five-month period before the 2009 German national election. Most strikingly, one has to ignore some of the YouTube conventions to be successful on the platform during an election campaign, like uploading user-generated content.     

Der sogenannte Auffüllungsanspruch bei der Mietkaution – insbesondere in der Insolvenz

In einem rezenten Judikat hatte sich der OGH mit einer zentralen Frage zur Mietkaution zu befassen. Entscheidungswesentlich war, ob und aus welchem Rechtsgrund der Bestandgaber im Fall von Mietzinsrückständen die Wiederauffüllung der vom Bestandnehmer bestellten Kaution auf den ursprünglichen erlegten Betrag verlangen kann. Zu prüfen war dabei auch die Behandlung dieses Anspruchs in der Insolvenz des Bestandnehmers. Der Beitrag stellt die wesentlichen Aussagen der Entscheidung vor, analysiert ihre Konsequenzen kritisch und zieht Schlussfolgerungen für die Praxis.     

Suspicious circumstances on discovery of the cadaver

The authors report on three autopsy cases in which the findings at the death scene gave rise to the suspect of non-natural, in two cases even violent causes of death. The medico-legal and criminalistic investigations led to surprising results: Death was due to acute intoxication with narcotics, supposed delirium tremens and a suicide attempt in the presence of bronchopneumonia. External force was ruled out in all three fatalities by cooperative work of police investigators and forensic medicine.     

Forensic interpretation of Y-chromosomal DNA mixtures

The mathematical concept previously introduced for the forensic interpretation of DNA mixtures using non-associated genetic markers has been adapted to the assessment of haplotypes. Such calculus is required, for example, when Y-chromosomal markers are used in forensics. In addition to outlining the general mathematical framework, we devise two approaches to its practical computational implementation, involving either the inclusion-exclusion principle of probability theory or a recursion in the number of unknown contributors invoked. The two approaches scale differently, depending upon the complexity of the case and the diversity of the markers used. The performance of Y-chromosomal microsatellites (Y-STRs) as a means of trace donor discrimination has been assessed by simulation, using the derived formulas. Based upon data from the Y-chromosomal Haplotype Reference Database (YHRD), the exclusion chance of a non-contributor is shown to vary between 95% in the case of two contributors, and 70% for five contributors. With only one additional contributor, half of all contributing suspects would yield a log-likelihood ratio in favour of donorship of 1.61 or higher, although the median drops to 0.66 with four additional contributors. It must be emphasised that these estimates of the discriminatory power of Y-STRs are likely to be conservative since the simulations involved only haplotypes known to occur in YHRD.     

Review: Pharmacokinetics of illicit drugs in oral fluid

This article reviews studies that have measured drug concentrations in oral fluid following controlled dosing regimens. A total of 23 studies have been identified over the last 15 years. These show that the amphetamines including designer amphetamines, cocaine, cannabis and cocaine are quickly found in oral fluid following dosing and usually have similar time-courses to that in plasma. Following common doses peak oral fluid concentrations exceed 0.1 microg/mL and often even 1 microg/mL. The drug concentration will depend on whether a dilution step occurs with buffer as part of the sampling procedure. The uses of collectors that stimulate oral fluid usually reduce the drug concentration compared to a non-stimulated manner. This reduction will not disadvantage the recipient since it will potentially reduce the detectability of drug in oral fluid compared to non-stimulated collections. Only one recent study has been reported for a benzodiazepine. This showed nanogram per milliliter concentrations for flunitrazepam. More studies are required for benzodiazepines and indeed for other drugs, particularly in multiple drug situations and where disease may affect the pharmacokinetics of drugs.     

First‐Hand Experience and Second‐Hand Information: Changing Trust across Three Levels of Government

Little is known about how different sources of information drive citizen trust in government. To address that gap this article compares disaster evacuees to observers, noting how trust differs as attention to media coverage increases. First‐hand experience supplies information to update trust through biological and personal processes and performance assessments, while secondary sources provide information about other people's experiences, filtered through lenses that take an active role in crafting information. These two types of information have varying effects depending on the level of government being trusted. Using surveys administered a year after Hurricane Katrina, I find that Katrina evacuees have the highest trust in federal government, until they start paying attention to media coverage, and that attention to coverage has the most dramatic effect on these evacuees compared to all other groups. I also find that increasing attention to second‐hand information corresponds with higher trust in local officials, and that this effect decreases as the level of government increases. It appears media coverage creates a comparison in the mind of hurricane evacuees, causing them to update their performance assessments based on comparing their own experience to that which they observe, thereby updating their political trust.     

Demands on scientific studies in different fields of forensic medicine and forensic sciences. Traffic medicine--impaired driver: alcohol, drugs, diseases

Since human performance is a key factor in crash causation detailed knowledge of the involvement of alcohol, drugs and diseases is of fundamental interest for road safety. To better understand the effect of these influencing factors it is important to use a combination of witness observations and a range of experimental and epidemiological studies. Epidemiological approaches to research such as road-side-surveys, case-control-studies, culpability analysis, pharmaco-epidemiological studies are usually seen as being able to provide the best answers. This article discusses the relative merits of experimental and epidemiological approaches.     

Age estimation and the developing third molar tooth: an analysis of an Australian population using computed tomography

The third molar tooth is one of the few anatomical sites available for age estimation of unknown age individuals in the late adolescent years. Computed tomography (CT) images were assessed in an Australian population aged from 15 to 25 years for development trends, particularly concerning age estimation at the child/adult transition point of 18 years. The CT images were also compared to conventional radiographs to assess the developmental scoring agreement between the two and it was found that agreement of Demirjian scores between the two imaging modalities was excellent. The relatively wide age ranges (mean ± 2SD) indicate that the third molar is not a precise tool for age estimation (age ranges of 3-8 years) but is, however, a useful tool for discriminating the adult/child transition age of 18 years. In the current study 100% of females and 96% of males with completed roots were over 18 years of age.
