The effects of delay on voice recognition accuracy

Two experiments were conducted in which 176 listeners heard male and female objectively defined high- and low-recognition voices and then attempted to identify these voices from a voice parade containing 20 distractors after either 10, 40, 100, or 130 minutes (experiment 1), or 10 minutes, one day, seven days, or 14 days (experiment 2). In experiment 1 delay had no overall effect, although further analysis revealed that the shortest delay did produce better performance than all other delay conditions. Further, high-recognition voices were better identified than low-recognition voices. In experiment 2 delay had an overall effect, with the shortest delay interval again being significantly better than all other conditions, which did not differ among themselves. High- and low-recognition voices, however, did not exhibit a statistically significant difference, although these two factors entered into a marginally significant interaction. Theoretical speculation and forensic implications were drawn.This research was funded by the British Home Office, research grant no.

FDA regulation of medical software

Currently the FDA is reviewing its policy on the regulation of computer software in the medical arena. Healthcare practitioners hope that the FDA will take the least possible regulatory action required by law to fulfill its public health responsibility and will take into account the unique status of the ever-changing software industry. Innovations in telemedicine and medical informatics have yielded significant improvements in the quality and cost of healthcare, and the imposition of cumbersome regulatory requirements on the medical software industry would slow the development and introduction of medical software products.     

Youth participation and agency in the United Nations Framework Convention on Climate Change

This article examines the participation and agency of young non-state actors (NSAs) in the United Nations Framework Convention on Climate Change (UNFCCC). It utilizes the constituency of Youth NGOs: YOUNGO, as a case study to examine the relationship between selection of participatory strategies, power sources (following Nasiritousi et al. in Int Environ Agreem Politics Law Econ 16(1):109–126, 2016), recognition and agency using ego and alter perceptions. It finds that young people’s selection of participatory strategies and power sources is shaped by the level of agency which they perceive to be available to them. When self-perception of agency is high, young participants offer constructive policy amendments which can lead to recognition and agency, though only within certain policy areas and the silos in which they are negotiated. When self-perception of agency is low, youth interpret this as lack of recognition, leading to efforts to assert their relevance and/or to challenge procedural legitimacy: neither of which are well received by decision-makers. In reality, several of the challenges faced by young participants are not structurally unique to their constituency; however, their lack of financial resources does hinder their ability to fully utilize modes of participation which previous studies have found to be beneficial to other NSAs, such as side-events. Financial constraints also restrict the ability of youth participants, many of whom are volunteers, to develop professional relationships with key actors over time, meaning that the level of agency developed by more established, better-resourced NSAs remains largely out of reach. These findings have implications for the understanding of NSA agency, which has previously been treated as homogeneous and raises further questions regarding procedural legitimacy of the UNFCCC and its role in mobilizing and empowering the next generation.     

Lord Woolf's Access to Justice: Plus ça change…

The one great principle of the English law is to make business for itself. There is no other principle distinctly, certainly and consistently maintained through all its narrow turnings. Viewed by this light it becomes a coherent scheme, and not the monstrous maze the laity are apt to think it. Let them but once clearly perceive that its grand principle is to make business for itself at their expense, and surely they will cease to grumble. (Dickens, Bleak House, Ch XXXIX)     

A severe case of multiple metal poisoning in a child treated with a traditional medicine

A child who had been treated orally with a traditional medicine was admitted to hospital with diarrhoea, vomiting and severe metabolic acidosis. Following treatment for renal failure and supportive therapy, the child was discharged well. Analysis of the traditional remedy, a black powder, using inductively coupled plasma-optical emission revealed very high concentrations of iron and manganese. Other metals were also present at lesser, but still high concentrations. The composition suggested that this was a sample obtained from a surface fracture in Transvaal dolomite.Metal poisoning is not uncommon following the use of non-herbal traditional remedies in South Africa, but in this case the mixture appears to have been a combination of many metals and salts.
