Functioning Well in a Dysfunctional System: Recommendations for Clinical Psychologists in Workers’ Compensation Settings

Clinical psychologists working in workers’ compensation (WC) settings face unique and complex professional and ethical challenges. The present paper provides recommendations to clinical psychologists for avoiding the largely unintentional harm to clients and unethical practices that can occur within the realm of WC. Although the psychologists working in WC settings more often than not act in ethical ways grounded in years of academic and professional training, the unique tasks required of psychologists in WC settings (e.g., rating injuries; determinations of causality) and the pressures inherent in the system can potentially lead even the most well-intentioned mental health professionals into unsavory ethical and professional scenarios. The authors examine the (un)witting contributions of psychologists to the current dysfunction in the WC system and provide recommendations for traversing the oft-serpentine terrain of mental health evaluations and treatment in WC settings. Specifically, the authors discuss, among the many possible potential pitfalls, (1) bringing personal bias into the evaluative setting, (2) engaging in unsavory advertising practices, (3) cherry-picking and other missteps in record review, (4) engaging in cursory consenting, (5) failure to engage in evidence-based assessment and report writing, and (6) role challenges.     

Problems of assessing sibship probabilities by means of genetic analysis

Nowadays, kinship studies based only on STR analysis are a very common practice. Apart from regular paternity cases, there is a rising number of cases in which the type of sibship between two persons has to be determined. Very often the parents or further relatives are unavailable for testing, so that the probability e. g. for a half-sibship has to be calculated as a deficiency situation. 50 unrelated persons (Group 1), 50 full siblings (Group 2), and 50 half-siblings (Group 3) were genotyped using the 15 STRs comprised by the AmpFlSTR Identifiler multiplex PCR-kit to investigate the reliability of common statistics programs and the indicative value of the calculated probabilities. Using a commercially available statistics program, we calculated probabilities for the following hypotheses: 1. The persons investigated are full siblings; 2. the persons investigated are half-siblings; 3. the persons investigated are unrelated. After STR analysis, half-sibling probabilities between 0.03 %-97.56% for group 1, between 0.01%-78.46% for group 2, and between 24.28%-90.18% for group 3 were calculated. In addition, the authors present two complicated deficiency cases which could be resolved only by extensive DNA typing using X- and Y-chromosomal loci, respectively, as well as the investigation of further relatives. The results of this study suggest that typing of autosomal STRs alone is no sufficient tool for resolving cases of possible half-sibship, even if probabilities of more than 90.0% are obtained. Due to the results of our study we suggest the implementation of mandatory standards for the investigation and interpretation of complicated kinship cases.     

Possible pitfalls in motherless paternity analysis with related putative fathers

Nowadays, more and more paternity cases are carried out investigating only child and putative father, mostly for economical or private reasons. Usually, reliable results can be obtained and the putative father can be included or ruled out with a high certainty. Considerable problems might arise when a relative of the biological father is investigated as being the putative father. In this study, we investigated 164 persons from 27 families creating artificial deficiency cases using the AmpFlSTRIdentifiler kit, which amplifies 15 STRs simultaneously. We analyzed 93 child/biological father pairs and the corresponding uncles, respectively the brothers of the biological fathers. The average paternity probability for the biological father was 99.9699% (paternity index (PI): 3321.26); only in three cases the results were under 99.9%. In five out of 125 child/uncle pairs no STR mismatches were found and paternity probabilities between 99.9726% (PI 3652) and 99.9970% (PI 33,545) were calculated. The average number of excluding loci was 3.4, but in 31.2% of the cases only zero, one or two mismatches were found. When both putative fathers were genetically typed, the biological father usually had a statistically higher paternity probability. Nevertheless, the differences between probabilities for father and uncle were only small. These results show that a reliable investigation of deficiency cases (i.e. child and putative father) seems to be more difficult than generally assumed. Especially in cases with an unknown familiar background and/or when investigating foreigners for immigration purposes, the laboratory expert should include the mother, increase the number of investigated loci or include a second method such as RFLP-analysis, some serological systems or typing of X-chromosome specific STRs to further ascertain the results.     

Development of a capillary zone electrophoresis method including a factorial design and simplex optimisation for analysis of amphetamine, amphetamine analogues, cocaine, and heroin

A capillary zone electrophoresis (CZE) method was developed for the analysis of amphetamine and 13 amphetamine analogues. A full factorial design was used to screen for important design variables (i.e. carrier electrolyte concentration, pH, and separation temperature), and a modified simplex was employed in a final optimisation step. The resolution values of the target compounds were used as responses in the screening and optimisation phases. This approach made it possible to control the effects of the design variables on the separation of the target compounds. The best results were obtained using a 100mM Tris/phosphate buffer (pH 3.1) at a separation temperature of 10 degrees C, and the analysis time was 23 min under these conditions. After slight modification, the method also enabled baseline resolution of the most commonly encountered amphetamine derivatives, as well as cocaine and heroin, within 7 min. There was a linear relationship between peak area and concentration for all substances, with correlation coefficients in the range of 0.9975-0.9999. Moreover, the technique was repeatable and exhibited relative standard deviation (R.S.D.) values in the ranges of 0.01-0.11% and 0.54-1.60% for relative migration time and corrected peak area, respectively. Lastly, the method was successfully applied to analyse street samples.     

Transnational organized crime challenges for future research

This essay and review seeks to assess the state of empirical research on transnational organized crime, drawing on a review of the English language academic literature. It identifies major themes and research questions as well as methodological approaches, and summarizes key findings. It also addresses challenges to meaningful research, arguing that internationally coordinated research projects will be necessary in the future to arrive at the insights necessary to inform theory and policy.     

Regulating government (’s share): the fifty-percent rule of the federal constitutional court in Germany

Some numbers in the political sphere seem to be chosen rather arbitrarily. One example might be the rule set out by the Second Senate of the German Federal Constitutional Court in 1995 that the overall tax load on assets must be limited to 50% of the yield on those assets. This rule was understood by many as a general principle for taxation. The article first sketches the socio-political climate under which the rule originated: a rise of neo-liberal thought met with the inability of the political institutions to reform the German welfare state with its ever-growing expenses. The Constitutional Court’s intervention is interpreted as a reaction to this stagnation in politics. An analysis from the perspective of Constitutional Law, however, reveals that the 50% rule cannot be convincingly based on the German Basic Law, and instead must be seen as a political move of the Court. But this move did not follow an economic rationality, either; for an optimal government’s share can only be determined in relation to the economic performance of a country and not by fixing it generally at a maximum of 50% of GDP. The demise of the 50% rule already began four years later. In 2006, finally, the Senate moved away from the individual rights-based approach of 1995 to a more general assessment, taking also into account an increasingly globalized tax competition. The reason for this clear-cut change in the Court’s jurisprudence can be found in a change of the socio-political and institutional parameters, thus witnessing to the effect of the political climate on court decisions. The analysis also shows that the rule was created and abandoned only on the basis of an “introverted” legal discussion, economic arguments hardly playing any role in the process. The new line of the Senate, however, might guarantee for a better integration of economic science into tax policy by exchanging fixed limits for a “discursive” model, demanding from the tax legislator better reasons for higher taxes.
