Petechial Hemorrhages and Ethanol in Deaths from Intoxication

Petechiae in conjunctivae and in the palpebrae/skin of the eyelids are of particular interest for the forensic pathologist, because of their association with pressure on the neck. They have been described in the eyelids of intoxicated persons both in case reports and in text books of forensic pathology. We studied 590 deaths caused by intoxication, and 75 had petechiae either in the conjunctivae, the eyelids, or in both locations. We examined the influence of drugs and ethanol on the location of the petechial hemorrhages in these deaths. Deaths with ethanol in blood and in urine/vitreous humor more often had petechiae in both locations than those without. This association was statistically significant, independent of body position and livor mortis. No association between the location of petechiae, medicinal drugs, or narcotics was found. These results suggest that ethanol may contribute to the development of petechial hemorrhages in deaths from intoxication.     

Fluorescence Imaging of Posterior Spiracles from Second and Third Instars of Forensically Important Chrysomya rufifacies (Diptera: Calliphoridae),

Entomological protocols for aging blowfly (Diptera: Calliphoridae) larvae to estimate the time of colonization (TOC) are commonly used to assist in death investigations. While the methodologies for analyzing fly larvae differ, most rely on light microscopy, genetic analysis, or, more rarely, electron microscopy. This pilot study sought to improve resolution of larval stage in the forensically important blowfly Chrysomya rufifacies using high‐content fluorescence microscopy and biochemical measures of developmental marker proteins. We established fixation and mounting protocols, defined a set of measurable morphometric criteria and captured developmental transitions of 2nd instar to 3rd instar using both fluorescence microscopy and anti‐ecdysone receptor Western blot analysis. The data show that these instars can be distinguished on the basis of robust, nonbleaching, autofluorescence of larval posterior spiracles. High‐content imaging techniques using confocal microscopy, combined with morphometric and biochemical techniques, may therefore aid forensic entomologists in estimating TOC.     

Unwanted Online Attentions Among an Italian Students Sample

The use of the Internet and new technologies now seems to permeate the entire society, affecting every aspect of daily life. Although this change is characterized by undeniable positive aspects, it simultaneously bears a number of risks which are higher especially with respect to the growing number of younger users. In fact, young people, as the most involved in cyber space, are an age group most exposed to the dangers of improper and not aware use of electronic tools. The specific aim of this research was to study unwanted online attentions (UOA) among a sample of Italian students (N?=?585, mean age?=?14.5), identifying UOA as all those behaviors carried out through the Internet and technology to annoy, disturb, offend, humiliate, intimidate, threat, harass, harm or attack others. The online questionnaire investigated the online habits of the students, the presence of UOA and the characteristics of victims and perpetrators, the perception and emotional impact of such conducts, and the victims' possible reactions. The findings offer an estimate of the prevalence of these behaviors in the population of this age group in the area considered. More importantly, the results reveal a very high involvement in technology by the students accompanied by a lack of awareness regarding the risks connected to technology use as well as a low perception of UOA. These results give evidence of the needs in terms of prevention and education instruments in order to improve the system of responses to cybervictimization among young people.     

Determinants of the university technology transfer policy-mix: a cross-national analysis of gap-funding instruments

University–industry technology transfer (TT) has become increasingly institutionalized and is supported by numerous reforms and initiatives at the national, regional and university levels. Most countries have implemented a policy mix involving a range of instruments to support the commercialization of research. Still, there is no systematic evidence indicating why the mix of policy instruments differs between countries. This study offers a novel cross-national investigation of the policy mix emphasizing the level of centralization and decentralization of policy instruments. We map and analyze two specific types of public instruments aimed at addressing the so-called funding gap in TT: proof of concept programs (POCs) and university-oriented seed funds (USFs). Based on a survey across 21 European countries, we find that such instruments are widely used but are organized differently depending on the level of implementation of TT practices in the country and the specific type of instrument considered. More precisely, we find a U-shaped relationship between the use of centralized gap-funding instruments and the country’s implementation of TT practices. Moreover, the type of gap-funding instrument (POC or USF) moderates this relationship. We discuss the implications of our findings and suggest that the policy mix of gap-funding instruments evolve with the maturity of the national TT infrastructure.     

'Your personality is the intervention': a grounded theory of mental health nurses’ beliefs about hope and experiences of fostering hope within a secure setting

Hope is an important factor in psychological resilience and change, and recovery from mental health difficulties. Recently, there has been an increased focus on recovery-oriented practice within forensic mental health settings. Several policies include calls for mental health practitioners to inspire hope for recovery in the individuals they work with. However, there is little suggestion of how to implement such recommendations in practice or research exploring how staff foster hope in forensic settings. This study used grounded theory to explore nurses’ perspectives and experiences of hope within a medium secure setting. A model was developed from the data that integrated nurses’ beliefs about hope, practices to develop service users’ hope and the emotional impact of this work. The nurses’ values played a significant role in their work to develop hope. Recommendations are made to help manage the emotional impact and address challenges unique to fostering hope within forensic settings.     

Bribery and Public Debt Repudiation

In cases where policy makers accept ``bribes'' offered by organised lobbies or interestedparties, government decisions can be modelled as a first price menu auction. In this paper we adaptthis structure to model debt repudiation. We considera one-period model in which two generations, parents and children, are present, and debt titles are unevenlydistributed among parents. The government can repaythe debt by a combination of taxes on the children'sincome and on the outstanding debt. We excludeintergenerational conflicts, assuming that the parents'and children's objective is to maximise the utility ofthe family. In this perspective, families make offersthat relate monetary contributions to the taxstructures chosen by the government. On the hypothesisthat all interests are represented, we obtain theresult that the government is indifferent to the taxstructure.
