Analysis of the Effect of Cyclophosphamide and Methotrexate on Chrysomya megacephala (Diptera: Calliphoridae),

Forensic entomotoxicology investigates the effects of chemical substances in the development of scavenger insects and the reflection on estimating the minimum postmortem interval (PMI). To evaluate the impact of the chemotherapeutic drugs cyclophosphamide (CF) and methotrexate (MTX) on the postembryonic development of Chrysomya megacephala, controlled experiments were performed by rearing the larvae on spiked minced beef with different concentrations of these drugs. The results indicated that CF significantly decreased their developmental rate up to 28 h but had no significant effect on larval and adult sizes, survival rate, and sex ratio, whereas MTX decreased larval and adult sizes, survival rate, and there was a deviation in the expected sex ratio toward females in MTX‐exposed larvae but had no significant impact on developmental rate. These negative interference factors should be considered in cases of suspected death of people that have undergone chemotherapy.     

Fatal Hemorrhage from an Arteriovenous Fistula

In this study, we present two cases of sudden deaths of people with end‐stage kidney with arteriovenous fistulas for long‐term hemodialysis treatment. This procedure is associated with a number of known complications. While stenosis, thrombosis, and infection are well known, lethal hemorrhage from arteriovenous fistula is much less commonly encountered. Inspection of the bodies at the scene of the death by a medical examiner suggested that the deaths were due to exsanguination. Autopsies revealed visible defects on the front wall of the arteriovenous fistulas. Microscopic examination showed wall necrosis with infiltration of various inflammatory cells. Deaths were due to exsanguination from the ulcerated arteriovenous fistulas in patients with chronic renal failure. Further investigation revealed that complications in the area around the arteriovenous fistulas were known and were being treated until a sudden rupture of the vessels and hemorrhage from the arteriovenous fistulas resulted in the deaths.     

The Politics and the Demographics of Veganism: Notes for a Critical Analysis

The present essay aims to offer some reflections concerning the cultural and political aspects of veganism, on the basis of the available surveys and statistics, plus some more gathered by the authors—with the tools of different methodologies, including the semiotic one. After an introduction to veganism as phenomenon and movement, with general reflections and also a number of specific data, the essay proceeds to focus on the more political aspects, with an emphasis on some of the most intriguing and multifaceted data, such as the prevalence of female gender, leftist political inclinations and atheism within the vegan community. While the first connection has already been widely discussed (and to our mind, proved) since the times of Adams (The sexual politics of meat: a feminist-vegetarian critical theory, Continuum, New York, 1990), much less has been said (particularly at academic level) about the significance leftist ideologies and atheism within veganism. Moreover, within the domain of semiotics, this topic is entirely unexplored.     

Children’s voices on equal time-sharing arrangement following parents’ divorce

The article presents the final part of an Icelandic research project on parents and children of divorce, focusing on grown-up children’s experiences of equal time-sharing arrangements, ETSA, after their parents’ divorce. It consists of a quantitative analysis of firstly a nationally representative sample mapping the frequency and experience of 18–59 years old individuals of ETSA after parents’ divorce, and secondly a qualitative analysis of 16 long interviews with 16 children of divorce reflecting on their experiences. Both analyses indicate different experiences of this type of arrangement. The reality of the arrangement in practice is that parents chose the arrangement on the basis of their own preferences rather than a court imposing it or because the generally accepted core conditions for a positive outcome for children were in place. These negative experiences of ETSA are discussed in further detail and the need for law reform and service improvement is considered.     

Acid alteration of several ignitable liquids of potential use in arsons

Ignitable liquids such as fuels, alcohols and thinners can be used in criminal activities, for instance arsons. Forensic experts require to know their chemical compositions, as well as to understand how different modification effects could impact them, in order to detect, classify and identify them properly in fire debris. The acid alteration/acidification of ignitable liquids is a modification effect that sharply alters the chemical composition, for example, of gasoline and diesel fuel, interfering in the forensic analysis and result interpretation. However, to date there is little information about the consequences of this effect over other accelerants of interests. In this research paper, the alteration by sulfuric acid of several commercial thinners and other accelerants of potential use in arsons is studied in-depth. For that purpose, spectral (by ATR-FTIR) and chromatographic (by GC–MS) data were obtained from neat and acidified samples. Then, the spectral and chromatographic modifications of each studied ignitable liquid were discussed, proposing several chemical mechanisms that explain the new by-products produced and the gradual disappearance of the initial compounds. Hydrolysis, Fischer esterification and alkylation reactions are involved in the modification of esters, alcohols, ketones and aromatic compounds of the studied ignitable liquids. This information could be crucial for correctly identifying these accelerants. Additionally, an exploratory analysis revealed that some of the most altered ignitable liquid samples might be very similar with each other, which could have impact on casework.     

Stranger rape: classifying Spanish sexual offences using multiple correspondence and cluster analyses

We have analysed the information in 342 police reports of stranger sexual offences recorded in 2010. We have carried out a multiple correspondence analysis and a cluster analysis using modus operandi variables to identify differential profiles in these types of sexual offences. We have come up with three profiles of stranger sexual offences, which concur in the two techniques used. By analysing the personal variables of the offenders with such profiles, we have found differences in terms of the offender’s country of origin and age. We will discuss the consequences of these results on the police investigation of stranger sexual offences.     

Education for territorial peace in Colombia: what role for transrational peace?

ABSTRACT

In this article, we present the idea of a territorial peace and explore it in the context of Colombia. We locate our investigation in peace education, particularly in Colombia’s Catedra de Paz, and explore the adaptations and application of the iPEACES programme (originally the iPEACE programme, developed by one of the authors with Bevington in 2017) as a possible way of contributing to sustaining the plurality of many peaces in this and other contexts. We outline the Innsbruck school’s many peaces approach and Elicitive Conflict Mapping (ECM) framework in order to show how they contributed to developing the iPEACES programme – which is responsive to territorial peace in the Colombian context. We end by presenting limited findings from four surveys with teachers in Colombia who attended a taster day for the iPEACES programme in 2018. We discuss their contributions and perspectives, and the ways in which we feel the iPEACES programme might be taken up more widely in schools in Colombia and elsewhere.     

Where Do I Belong? Narratives of Rodina among Russian-speaking Youth in Kazakhstan

Abstract

This essay engages critically with the personal narratives of rodina (home, motherland) among Russian-speaking youth in post-Soviet Kazakhstan. It is argued that the concept of rodina as an important locus of belonging cannot be imbued with a single meaning; instead, it is characterised by internal conflicts and variations. Supported by empirical material, the essay moves beyond the confines of ‘nation’ and ‘nationality’ to illustrate the different ways in which Russian speakers frame their perception of rodina, and how such narratives can influence the construction of self- and community-identification.     

Understanding Multilevel Governance Processes through Complexity Theory: An Empirical Case Study of the Quebec Health-Care System

This paper aims to contribute to a better understanding of multilevel governance processes. We do so by focusing on the in-depth examination of the institutional changes recently implemented in the Quebec health care delivery system that require a close collaboration between interdependent actors acting at various levels of governance. Our three research questions are: (1) How does multi-level governance emerge in a pluralist institutuional context? (2) How do multi-level governance processes shape the adaptive capacity of the organization to its environment? (3) How does institutional context influence these multi-governance processes?Our empirical investigation is inspired by the theory of complexity which invites us to pay attention to three processes: self-organization, eco-self organization and co-evolution. This study shows that the effectiveness of multi-level governance processes do not only go through the implementation of instruments aiming at aligning the action of lower government levels with the objectives of the upper levels as suggested by numerous existing works. More precisely, it suggests that more distributed and coordinated processes favor a more homogenous form of adaptation (Miller and Page, 2007) taking into account the interdependence between stakeholders.     

The Contribution of Open Government to Prosperity of Society

The study finds that open government does not only have effect on economic prosperity, but on social capital and environment through the mechanisms of Rule of Law and Control of Corruption. The role of Rule of Law and Control of Corruption are emphasized in this study, because of their significance in mediating open government and prosperity. Unless mechanisms like regulation formulation, law enforcement and control of corruption are not put into practice; open government itself will not be a driving force to a prosperous society.
