Nitrous Oxide Determination in Postmortem Biological Samples: A Case of Serial Fatal Poisoning in a Public Hospital*

Abstract: In a public hospital, eight cases of fatal poisoning by nitrous oxide (N₂O) occurred under oxygen administration, due to an erroneous swapping of the lines in the gas system. The aim of the study was to clarify the factors involved in asphyxia by characterizing gases from different lines and measuring N₂O concentrations in postmortem biological samples from bodies exhumed. Analyses carried out on the gas system confirmed the erroneous substitution of O₂ line with N₂O and air line with O₂. Consequently, high N₂O amounts were revealed in several tissues and gaseous biological samples. All specimens were analyzed by headspace gas chromatography technique. A rigorous quantitative analysis was possible only in blood (11.29–2152.04 mg/L) and urine (95.11 mg/L) and in air samples from stomach and trachea (from 5.28 to 83.63 g/m³). This study demonstrates that N₂O can be detected in biological samples even 1 month after death.     

The Multiple Bases of Social Return Platforms: Evidence of a Brazilian Initiative

The literature on platforms emphasizes the balance between supply and demand as precursors to network expansion, strategy development and strategy sustainability. This study questions this logic through the exploratory approach of a public platform based on social returns. Results demonstrate that when an institutional force supports a platform concerned with diffuse and collective interests, it is possible that the strategy could sustain and develop without the balance of its forces. The study contributes to the strategic platform literature by pointing out the distinct aspects of social platforms and underlining the support generated by institutions.     

Ex-combatants as social activists: war,peace and ideology in Burundi

In both academic literature and policy discourse, ex-combatants are at times depicted as a threat to peace rather than agents of positive change. However, many of my ex-combatant interlocutors in Burundi were working actively on conflict resolution and peace-building projects. In addition, their experience and knowledge of combat was frequently stated as a deterrent for going back to such a situation. Though it may seem contradictory, the reasons my informants gave for having joined the war sounded remarkably similar to motivations for social activism. They usually expressed it as a desire to contribute to a better, more just, community. I argue that ideology played an important part in motivation to join armed groups during the war and carries over in participation in social activism today. These decisions need not be seen as polar opposites, but rather as similar motivations towards contributing to positive change taken in different circumstances.     

A Solution to the Crimean Crisis: Egalitarian Shared Sovereignty Applied to Russia,Ukraine and Crimea

Abstract

Sovereignty is intrinsic to conflict in international relations. There are various sovereignty disputes around the world caught between legal and political limbo, the status quo and continuous tension, with various negative consequences for all the parties involved. It is increasingly clear that the available remedies have been less than successful, and that a peaceful and definitive solution is needed. The essay considers how theories of distributive justice, and particularly the hypothetical thought experiments proposed by Rawlsian theory, can be used productively with the concept of sovereignty and explores the possibility of a solution for sovereignty conflicts such as the Crimean case by the application of a Rawlsian methodology.     

Seizures of Clandestinely Produced Tablets in Santa Catarina,Brazil: The Increase in NPS from 2011 to 2017

Ecstasy is the name given to a large group of substances known as “club drugs” traded in the form of tablets, powder and liquid that present a varied composition, including mainly 3,4-methylenedioxymethamphetamine (MDMA) and analogous substances, in addition to the growing presence of new psychoactive substances. Based on this, clandestinely produced tablets (“ecstasy tablets”) seized by police in Santa Catarina in the period from 2011 to 2017 were analyzed. During the study period, 3472 seizures occurred, which resulted in total 498,443 tablets seized. Seventy nine substances were identified. In the year 2011, about 90% of the tablets contained MDMA. This number decreased to 66.6% in 2017. On the other hand, there was an increase in the number of tablets that mainly contained synthetic cathinones, as well as tryptamine and piperazine derivatives. Police seizures in the metropolitan region of Florianópolis and on the coast prevailed over the rest of the state.     

Family farming in Brazil: evolution between the 1996 and 2006 agricultural censuses

This article compares the main findings of Brazilian agricultural census data of 1996 with the same of 2006 by applying the methodology known as ‘FAO/INCRA’ (Food Agriculture Organization/Instituto Nacional de Colonização e Reforma Agrária) which allows the characterization of family farms in relation to the total universe of farms. In this comparison several variables are shown, including the share of family farming in the total value of production, in the total number of farms, utilization of modern technology and partial factor productivity. Census data shows that family farming has changed from 37.91 percent of total production value to 36.11 percent during a decade of strong expansion of agriculture as a whole, demonstrating the economic relevance of this segment which, besides producing food, is integrated in the most important productive agricultural chains of the Brazilian agribusiness. Family farming is a heterogeneous segment, with different sub-segments. During the studied period of ten years the most rich of these sub-segments (A) has increased participation in total production, while the poorer sub-segments (C and D) have only grown in absolute terms without a corresponding increase in production.     

Manners of Killing and Rituals in Apulian Mafia Murders*

Abstract: The Apulian (South of Italy) territory saw the birth of a criminal organization called Sacra Corona Unita (SCU, United Holy Crown) which transformed the rules of traditional mafia organizations. This work examined 83 victims of the SCU between 1980 and 2000. The bodies were mainly of SCU members and in some cases, of police and law enforcement officers and other citizens caught in the crossfire. Some of these were discovered; thanks to the collaboration of “repented” SCU members who became police informers. The condition of the bodies varied in relation to the date and manner of killing. In some cases anthropometric research methods were necessary. In 73% of the cases, lesions of the head were the only marks left on the body. In conclusion, the existence of some social aspects connected with the symbolisms and membership rites that characterized the origin, evolution, and decline of the SCU is stressed.     

Assessing risk markers in intimate partner femicide and severe violence: a new assessment instrument

The aim of this study is to develop a scale to predict intimate partner femicide and severe violence. The sample consists of 1,081 batterer men who were reported to the police station. First, the most significant differences between the severe violence group (n = 269) and the less severe violence group (n = 812) in sociodemographic variables are determined. Both aggressors and victims of the severe violence group have a higher rate of immigration. Second, the proposed 20-item scale is derived from a larger 58-item scale, where only the most discriminative items between severe and nonsevere intimate partner violence are taken into account. Psychometric properties of reliability and validity are rather good. Cutoff scores have been proposed according to sensitivity and specificity. This easy-to-use tool appears to be suitable to the requirements of criminal justice professionals and is intended for use in safety planning. Implications of these results for further research are discussed.     

Dispositional empathy in neglectful mothers and mothers at high risk for child physical abuse

This study investigates whether mothers who are neglectful and at high risk for child physical abuse present a deficit in empathy. Participants were neglectful mothers (n=37), mothers at high risk for child physical abuse (n=22), and nonmaltreating mothers (n=37). The Interpersonal Reactivity Index, a self-report measure assessing specific dimensions of empathy, was used to assess dispositional empathy. No differences between neglectful and non-neglectful mothers were found for perspective taking, empathic concern, and personal distress. High-risk mothers reported less perspective taking and more personal distress than nonmaltreating mothers. No difference between groups was found for empathic concern. The present study supported the hypothesis that parents at high risk for child physical abuse show a deficit in particular aspects of dispositional empathy: personal distress and perspective taking. However, no differences were found between neglectful and nonmaltreating mothers in any dimension of dispositional empathy.     

Drug consumption among sexual offenders against females

This article aims to evaluate the role of drug consumption among sexual offenders against females. Three groups of participants (N = 133) comprising sexual offenders against girls, pubertal females, and women were examined with reference to history of drug and/or alcohol use, impulsivity level, sexual addiction, and recidivism risk. Sexual offenders against women were found to have significantly more difficulties with drug use, higher impulsivity level, and to be younger than the sexual offenders against girls and pubertal females. The combination of drug consumption and higher level of impulsivity may contribute to sexual aggression against adult females.
