‘Why do we need all this?’ A call against genetic engineering and reproductive technology

The central argument of this article is that the discussion on the new reproduction technology should not start with these technologies as such and their possible benefits and abuses but with the basic question whether we need this technology at all, whether the fundamental problems of women in capitalist-patriarchal societies can be solved by technology. According to the author, genetic engineering and reproductive technology are not only not capable of solving any of these questions, they are destructive to a human relation to our bodies, nature, other peoples. Exploitative and oppressive relations cannot be overcome by more sophisticated technology-even if it were in the hands of women—but only by a revolutionizing of these relations.     

Federal laboratory missions,products, and competitiveness

A number of initiatives over the past decade have tried to increase the federal laboratory system's impact on U.S. competitiveness, largely based on assumptions that the system is a reservoir of readily available technology appropriate to industry's competitive needs. However, there is a virtual absence of empirical data on the nature of research and development in the national laboratory system and the character of its R&D “products.” This paper reviews the limited data on R&D in the national laboratory system available from the General Accounting Office, the National Science Foundation, and the National Comparative Research and Development Project. The findings suggest that technologies available within the system are likely to emerge from the most strongly mission-oriented R&D, and are therefore the least likely to spin off and diffuse throughout the industrial base. Once the hardware needs of the Department of Defense (DOD), the Department of Energy (DOE), and the National Aeronautics and Space Administration (NASA) are excluded, most of the system's R&D output is fundamental knowledge, which flows through public domain literature and requires substantial additional processing to become commercial products. The implications are (1) there is no reason to believe the current federal laboratory system can directly enhance U.S. competitiveness; (2) in order for labs to contribute to competitiveness, they must have more explicit missions to do so; and (3) policy expectations of commercial impacts are inconsistent with policy requirements that labs conduct precommercial basic and applied research.     

Visualization of bridging veins by means of postmortem computed tomography

At autopsy, visualization of lesions of the bridging veins, a frequent source of subdural bleeding, is difficult due to their anatomical localization. On the other hand their demonstration is of great importance for the assignment to a chronologically defined trauma. For this reason a postmortem method using computed tomography was developed to visualize the intracranial venous system by means of X-ray contrast media. In subdural bleedings, in which the skull had not been opened up, ruptured vessels could be accurately localized with this method, so that targeted dissection was possible during the subsequent autopsy.     

Fungal DNA challenge in human STR typing of bone samples

The present study focuses on possible cross-reaction of fungal DNA with human STR primers that may affect subsequent forensic DNA analysis of forensic samples. Specificity of human STR markers namely HUMAMEL, HUMCSF1PO, D8S306, HUMTH01, HUMvWA, HUMFES/FPS, HUMF13A01, HUMDHFRP2, HUMFGA and HUMTPOX was tested using DNA of 24 different filamentous fungal isolates obtained from exhumed bone samples. The specificity of these ten STR markers for human DNA was demonstrated. Presence of non-human DNA in five bone samples analyzed did not alter scoring of detected alleles. Notably, amplification was inhibited in the presence of a high proportion of fungal DNA compared to human DNA (1000 ng: 1 ng) in DNA mixture experiments. The results of the present study underscore the importance of carefully analyzing the presence of non-human biological contaminants that may affect DNA typing of environmentally challenged forensic samples to avoid spurious data interpretation.     

Unexpected perinatal death and sudden infant death syndrome (SIDS): anatomopathologic and legal aspects

This work intends to be a review of the recent histopathological findings elicited by research into sudden and unexpected perinatal death and sudden infant death syndrome (SIDS) that have dictated a novel approach to the inherent problems by pathologists, especially those entrusted with forensic medical authority. The new approach stems from the recent advances made in the understanding of neuro- and/or cardiac-conduction-system diseases present in unexpected perinatal death and SIDS. These demand that an accurate morphologic examination be performed of these structures, which modulate respiratory, cardiovascular, digestive, and arousal activities, in all victims of sudden death. A histopathologic study of an ample register of cases of victims of sudden death, either perinatally or in early infancy, has demonstrated frequent alterations both of the autonomic nervous system (especially hypoplasia of the arcuate nucleus) and of the cardiac conduction system (accessory atrioventricular pathways). The present research provides an in-depth study of the many still-controversial aspects underlying perinatal unexpected death and SIDS and is recommended for professionals working in the forensic field, whose greater insight into this problem will allow more complete medicolegal documentation.     

Detecting Deception Via Strategic Disclosure of Evidence

Deception detection research has largely neglected an important aspect of many investigations, namely that there often exists evidence against a suspect. This study examined the potentials of timing of evidence disclosure as a deception detection tool. The main prediction was that observers (N = 116) would obtain higher accuracy rates if the evidence against the suspects (N = 58) was presented in a late rather than early stage of the interrogation. This prediction was based on the idea that late evidence disclosure would trigger lack of consistencies between the liars’ stories and the evidence; this could be used as a cue to deception. The main prediction received support. Late disclosure observers obtained an overall accuracy of 61.7%, compared to 42.9% of Early disclosure observers. Deceptive statements were identified with high accuracy (67.6%) in Late disclosure, indicating that the technique in this form is beneficial mainly for pinpointing lies.
