Differential diagnosis of vital and postmortem processes in burn cadavers

After presenting the most important intravitam reactions in 114 burnt corpses of the G?ttingen autopsy material covering the years 1969-83 two cases are described with a) a so called burn haemorrhage in the stomach b) an extremely wide spreading of the upper thighs. Differential diagnosis and forensic significance of these findings according to chemical, histopathological and experimental examinations are discussed.     

Adolescent Victim Types Across the Popularity Status Hierarchy: Differences in Internalizing Symptoms

Pubic bone age estimation in adult women

In recent years, numerous physical anthropologists have pointed out the need for regional standards for estimating age in various world populations. While investigating aging methods for East European populations, dramatic changes were noted in the pubic symphyseal morphology and structure of older adult female individuals. These changes were not captured in the typically used pubic symphysis aging methods. This paper defines and tests the need for a new phase, phase VII, that follows the Suchey-Brooks phase VI. In addition, Suchey-Brooks phases V and VI are redefined. Phase definitions, decision-making rules, and comparison graphics for the new method are presented. Balkan (n = 85) and Eastern Tennessee (n = 104) samples, totaling 189 individuals, were used in the analysis. Pearson correlation coefficients between four observers and a control seriation were strong, indicating ease of replicability between investigators. No statistically significant intra-observer error was detected. Summary statistics show that individuals in phase V were on average in the early 50s, while individuals in phase VI were in their mid 50s to mid 60s, and individuals in phase VII were in their mid 70s. Since linear regression models tend to under-age the elderly and over-age the young, transition analysis, using an unrestricted cumulative probit model, was undertaken to evaluate the phases and to produce point estimates for the ages-at-transition for the Balkan sample. The highest posterior density region point estimates with their associated upper and lower bounds can be used for predicting age for unknown forensic cases related to the Balkan sample. Further, the mean ages and standard deviations for phases V-VII for the Tennessee sample are presented for use in American forensic cases.     

Practicability of the mobile one-finger scanner Cross Match MV5 in fingerprinting of corpses: are mobile fingerprinting scanners suitable for use in mass disasters?

Dactyloscopy is a special field in the police records department and a suitable means for identifying unknown dead persons as well as solving crimes by taking fingerprints from living persons. Apart from the conventional methods of dactyloscopy, mobile and more compact instruments are to facilitate taking prints of fingertips and palms also at the scene of mass disasters. In the presented study, living persons and corpses were examined to find out the possible uses and limits of mobile one-finger scanners. The concrete issue of the investigation was whether the mobile one-finger scanner Cross Match MV5 is suitable for application in mass disasters. The device was used in 12 corpses aged 5 weeks to 76 years (mean postmortem interval 5.5 days) and in 28 living persons aged 6 weeks to 87 years. In summary, the scanner produced qualitatively good prints in all age groups of the living individuals. In the corpses, the prints were only partly evaluable. In particular, fingers and fingertips with soot blackening and livid discoloration were difficult to analyse. Postmortem rigidity also complicated the handling of the scanner. In fresh corpses, the scanner can be recommended without reservation. Even if the epidermis was detached, the scanner was able to produce evaluable prints of the dermis of the hypothenar.     

Sexual offenders in preventive detention: data concerning the inmates and expert witness practice

In the last decade, preventive detention-especially that relating to sexual offenders- has gained relevance for the German legal system. However, data are lacking concerning the inmates and the modus operandi of the psychiatric experts. Court orders and psychiatric statements of 114 offenders with orders of preventive detention were examined, 57 of whom were incarcerated because of sexual offences. Sexual offenders mostly show antisocial personality traits or even disorders, with a history of poly-trophic delinquency. In only four cases, the diagnosis of a sexual disorder was given. The analysis showed a high rate of psychiatric expert testimonies' lacking basic information, with incomplete assessment of sexual history. None of the experts used standardized prognostic instruments, meaning that most of the risk factors included in the Sexual Violence Risk-20 and the Static-99 were not considered. Further work needs to be done to improve the quality of psychiatric statements concerning sexual offenders.     

What motivates the engineers to patent? A study at the Chinese R&D laboratories of a European MNC

Corporate R&D engineers, being usually the initiators of a patent, are important contributors to the patenting performance of their employers. Hence, patenting motives of R&D engineers encompass an interesting and promising research field. However, the literature on patenting motivation of the engineers in the corporate context is scarce. We apply self-determination theory on human motivation to investigate patenting motives of a sample of local R&D engineers in China employed by a European-based multi-national corporation. Factor analysis reveals four groups of motives: “reward and recognition”, “reputation and promotion”, “making a contribution” and “interest and sense of achievement”. The results of multiple hierarchical regression show the influence of working climate on “making a contribution” and “interest and sense of achievement” motivation factors. Implications for patent management are discussed.

     

“Nerve” and violent encounters: An assessment of fearlessness in the face of danger

The findings from a large body of research on the ecology of violence indicate that individuals demonstrate a willingness to engage in violence to reduce their risk for violent victimization. Scholars have suggested that a reputation for toughness and aggression acts as an informal signal that deters mistreatment. Anderson (1999), in his street code thesis, in particular, argued that adherence to the street code functions as a signal that reduces violent victimization risk. Other research findings, however, reveal that the street code leads to an increase in victimization risk; moreover, violent offenders are routinely victimized at high rates given their lifestyle and routine activities. The evidence, therefore, does not show support for the position that a reputation for toughness or aggression effectively reduces violent victimization. In the current study, we operationalize the concept of nerve, which findings from criminological studies indicate is an important mechanism for protecting adolescents from victimization. Using data from the second national evaluation of the Gang Resistance Education and Training Program, we test this operationalization of nerve to determine whether the concept is associated with later violent offending and violent victimization in ways consistent with theory and research on the ecology of youth violence. Our results demonstrate support for the notion that nerve is positively associated with violent offending, whereas those at the highest levels of this construct experience fewer violent victimizations.     

Norway,Spitsbergen, and America, 1905-1920

In the Spitsbergen treaty of 1920, Norway acquired sovereignty over the Spitsbergen Islands. Rather than Woodrow Wilson, the American president, the architects behind the treaty were Robert Lansing, Wilson’s secretary of state, and, behind the diplomatic scene, the mining investor, John M. Longyear. In 1906, Longyear established a mining company to exploit the coal deposits at Spitsbergen. He induced Congress, the State Department, and the White House to forge an American policy for the European Arctic, including the appointment of Lansing, an international lawyer, as a counsel in the State Department. Lansing was a leading expert on both international law and the lack of state authority at the terra nullius, Spitsbergen. In 1915, he became secretary of State and, at the Paris Peace Conference, decided American policy regarding the Spitsbergen question. This analysis shows how the outcome of the Spitsbergen question was a result of American mining interests, supplemented by Norwegian-American shared interests in conflict resolution based on international law.     

Evaluating Transport Infrastructure Projects in Low Data Environments: An Application to Nigeria

Transport infrastructure consumes a large fraction of the development assistance envelope. Yet procedures for evaluating transport infrastructure projects are typically ad-hoc. This paper proposes an approach to assess the differential impacts of alternative investment proposals in data constrained environments where conducting reliable impact analyses is difficult. We first demonstrate a technique for estimating the cost of transporting products to markets. We then estimate the impact of improving the road network on economic activity. Finally, we perform simulations to demonstrate a methodology for prioritising alternative investments. The analysis demonstrates a pragmatic, though rigorous, approach for assessing transport infrastructure benefits.     

Small-Scale irrigation and income distribution in Ethiopia

Abstract

Irrigation stimulates agricultural productivity and economic growth, but this may come at the cost of growing inequality. Using data at community and household level, this paper analyzes the distributional impacts of irrigation in Ethiopia. Regression analyses reveal the direct effects of irrigation on expenditures and labour demand, and the indirect effects of irrigation on food prices and expenditures of non-irrigation households. The results indicate that past development of irrigation stimulated growth without deepening inequality, and that irrigation decreased dependence on food-for-work programs. Thus, irrigation has played a positive role in the development of Ethiopia.
