Skin changes following defibrillation. The effect of high voltage direct current

Previously, electrical injuries have been suggested caused only by the concomitant heat developed during the passage of an electrical current. Recent experimental studies on fully anesthetized pigs and the study of one human case have, however, shown typical electrical alterations. The purpose of the present study was further to evaluate the histology of electrically induced changes in the skin in humans. In addition, supplementary in vivo methods for evaluation of skin changes as high-frequency ultrasound and Raman spectroscopy were used. The skin of 11 patients treated with a defibrillation of the heart was examined for macroscopic changes, the skin of eight of them also for histologic changes and for changes observable via supplementary methods. Immediately and 7 days after the defibrillation, fractions of a narrow red ring were observed along the periphery of the tin-foil electrode. Epidermis showed signs previously observed following electrical influence: segmental alterations often related to the openings of sweat ducts, darkstaining or "empty" nuclei and homogeneous cytoplasm, eosinophilic or pale. Dermis did not show the specific sign of electrical influence: deposits of calcium salts on dermal fibres, neither via histologic examination nor via high-frequency ultrasonography and Raman spectroscopy. Fractions of a narrow red ring along the periphery of the electrode showing histological signs of electric influence in epidermis thus appear to be characteristic of high voltage electrical injury.     

Taking the bait: interrogation questions about hypothetical evidence may inflate perceptions of guilt

ABSTRACT

During suspect interviews, police will sometimes ask about hypothetical incriminating evidence to evoke a cue to deception – a technique known as a bait question. Previous research has demonstrated such questions can distort peoples’ memory for what evidence exists in a case. Here, we investigate whether such memory distortion can also cause people to see the suspect as more likely to be guilty. Across three experiments, we find exposure to bait questions led to participants hold inflated views of a suspect’s guilt. Further, we demonstrate bait questions cause reliable, robust memory distortion, leading participants to believe non-existent, incriminating evidence exists. However, we found no evidence to support the speculated mechanisms for this inflation – namely, (1) that source monitoring errors could lead people to misremember false evidence as real evidence and (2) that bait questions provide ‘key evidence’ to fill in the gaps of an incomplete theory of a case. In sum, bait questions have the problematic potential to shift jurors towards guilty verdicts. We suggest future research directions on bait questions, including the need for different designs to clarify why bait questions inflate guilt, and recommend practitioners avoid the use of bait questions.     

Menstrual fictions: languages of medicine and menstruation,c. 1850–1930

Abstract

Gynaecological narratives of menstruation in the late nineteenth century placed woman firmly within the orbit of domesticity by virtue of her biology. In the rhetoric of medical ‘truths’, menstruation was defined as a ‘ldisability’, a physical ‘illness’ and a threat to emotional stability. Thus, it was argued, women could not hope to achieve equality with men when the dictates of Nature (as opposed to society) stipulated that they remain mothers, carers and homemakers. This article explores the notion that narratives of menstruation were created and articulated through subjective readings of social and cultural truths: menstruation was perceived and defined through the medium of ideas relating to what femininity was and ought to be. An examination of the medical languages of menstruation articulated between 1850 and 1930 reveals that the creation of menstrual knowledge was in perpetual flux. What remained a constant, however, was the appropriation of the female body as a field for the definition of ‘difference’     

The Determinants of Capital Structure: Evidence from Chinese Listed Companies

This paper attempts to investigate the determinants of the capital structure of a sample of 972 listed companies on the Shanghai Stock Exchange and Shenzhen Stock Exchange in China in 2003. Various theories, namely, the trade-off, pecking order and agency theories, are deployed to explain and predict the signs and significance of each factor identified by Ragan and Zingales (1995) and Booth et al. (2001). Furthermore, we include institutional shareholdings, including state agency shareholdings, state-owned shareholdings and privately owned shareholdings, as corporate governance variables to examine the effects of corporate structure on the debt financing behaviours. As well documented, we find that profitability is negatively related to capital structure at a highly significant level. The size and risk of the firms are positively related to the debt ratio – but only in term of market value measures of capital structure. The years of the companies being listed on stock markets are positively related to capital structure, indicating the access of the firms to debt finance is more easily judged by book value. Tax is not a factor in influencing debt ratio. Ownership structure has a negative effect on the capital structure. The firms with higher institutional shareholdings tend to avoid using debt financing, a behaviour that can be explained by entrenchment effects. A further classification of the institutional shareholders reveals that, among the three groups of institutional shareholding, the state institutions, including state agency and state-owned institutions, were more averse to debt financing, particularly for state-owned institutions. There is no strong evidence indicating debt-averse behaviour by domestic institutional shareholders.     

Serving two masters: the interaction between Family and Medical Leave Acts and the ADA

The complex interaction between family leave acts and the new Americans with Disabilities Act (ADA) is just coming to light as employers begin to analyze how to comply with both laws. Specifically, the ADA implicates the procedures set forth in most family leave acts for verifying an employee's need for a leave through mandatory medical examinations and doctor's certificates. Many employees who are entitled to a leave of absence under state law are defined as "disabled" under the ADA. The ADA protects these employees with disabilities by regulating medical examinations and inquiries, and protecting the confidentiality of information obtained in such inquiries. This article offers some practical guidance for employers in providing leaves of absence under state family leave acts, while verifying the need for leaves in compliance with the ADA.     

‘Ground-Truthing’ Chinese Development Finance in Africa: Field Evidence from South Africa and Uganda

A new methodology, Tracking Underreported Financial Flows (TUFF), leverages open-source information on development finance by non-transparent, non-Western donors. If such open-source methods prove to be valid and reliable, they can enhance our understanding of the causes and consequences of development finance from non-transparent donors including, but not limited to, China. But open-source methods face charges of inaccuracy. In this study we create and field-test a replicable ‘ground-truthing’ methodology to verify, update, and improve open-source data with in-person interviews and site visits in Uganda and South Africa. Ground-truthing generally reveals close agreement between open-source data and answers to protocol questions from informants with official roles in the Chinese-funded projects. Our findings suggest that open-source data collection, while limited in knowable ways, can provide a stronger empirical foundation for research on development finance.
