In December 2020, the World Health Organization (WHO) declared SARS-CoV2 a global pandemic. Home confinement, low social contacts, and fear of virus transmission played a major role as risk factors for suicides during the following period. Suicide pacts, in particular, showed a different pattern. A rare case of a triple suicide pact among members of the same family nucleus is presented. The victims were an elderly, severely ill woman and her adult children (a son and daughter), linked by a morbid relationship. The last time the family was seen alive was 40 days before the discovery. All corpses presented decompositional changes. After a full autopsy, the cause of death was determined to be a lethal intake of morphine for the mother and acute blood loss due to self-stabbing at the neck for the siblings. The younger woman was under the effects of a large amount of heparin. Toxicological analysis was positive for opioids and alcohol in both siblings. Suicide pacts have rarely been described during the COVID-19 pandemic. In the few cases reported, the victims were more often relatives than people in a romantic relationship. The involvement of three people is unusual, as is the use of different suicide methods among the victims. In the presented case, the elderly mother's imminent death from terminal cancer, her concern over dying in a nondomestic environment, and the siblings' fear of being alone likely led to the conception of the suicide pact. Social isolation and economic difficulties also played a contributing role. 相似文献

Although party system change has been widely explored, it is less so for the regional level. The article provides the first systematic attempt to discuss party system change at the regional level in Italy. Through a comprehensive overview of the five 1995–2015 regional elections, indicators of party system change, based on an original database, are explored. It will be showed that in the 2013–15 election cycle while party system fragmentation, volatility and recomposition reached their maximum high – parallel to what happened in 1995 – the level of bipolarism, one of the main features of Italian party system since the mid-1990s, dramatically dropped replaced by a three-pole configuration. These results, and their consistency with the relevant junctures at the national level in 1994 and 2013, may allow to state that a party system change at the regional level occurred and thus to consider 2013–15 elections as critical. 相似文献

This article critiques interregionalism as a concept that is trapped in the European Union (EU) foreign policy toolkit narrative, which in turn structures what can be said meaningfully and legitimately about interregionalism. Drawing on the experience of the Arab–South American (ASPA) Summit, it shows that, when speaking on interregionalism in International Relations (IR), one need not be speaking about the EU interregional model, which is understood as a vertical relationship established between the EU and an objectified regional partner of its choice. Rather, a broader definition for interregionalism is proposed, one that builds up from the basic ‘region-to-region’ dialogue–arrangement–cooperation and interrogates the meaning it has for those who engage in this practice. This was made possible by the construction of a framework for the analysis of the practices that lead to the materialisation of the ASPA interregional discourse and that reveal how this form of interregionalism in the Global South ‘matters’ in IR. 相似文献

This study moves beyond theories emphasising “state failure” as the cause for terrorist “spill-over”. The aim is to offer new theoretical and empirical considerations concerning the determinants of terrorist groups’ geographical strategies. The main argument this article presents is that transnationality for nationalistic terrorist organisations can be costly. This is the case due to the mobility, social and strategic costs of operating beyond controlled territories. Hence, the article proposes an interpretation of these decisions as being mainly generated by states’ counterterrorism strategies. Using data gathered from the GTD Dataset and secondary sources such as specialised reports and strategic documents, the article explores the argument by presenting observations and empirical findings on two groups, AQIM and Boko Haram. 相似文献

This article re-visits the friendship of Vera Brittain and Winifred Holtby through some (largely unpublished) correspondence exchanged in 1926. Building on a body of literature which asserts the personal and professional importance of this friendship, my own analysis moves beyond what I identify as a polarisation of ‘work’; and ‘sexuality’ and reveals a friendship where professional and erotic interests are engaged in a dynamic exchange. In addition, I argue that the ways in which work and desire ‘trade’ with each other in this friendship are symptomatic of material and discursive conditions concerning women's work and sexuality in the interwar period. Specifically, ‘work’ will be seen to stand in for and legitimise a friendship which may be placed under censorious scrutiny, while ‘desire’ is displaced onto real professional ambitions which become possible at this historical moment. Brittain and Holtby were among scores of middle-class women becoming professional writers in large numbers for the first time in English history. Their ‘trade’ in work and desire invites more complex readings of other intense friendships which enabled women to succeed in professional life like never before. 相似文献

This article investigates the causes and content of the ongoing reform of the German Trade Union Federation (DGB). We argue that problems predating German unification ‐ in particular, a skewed demographic profile, financial crisis and waning political clout ‐ are the central factors that led German unionists to undertake reform and have largely determined the reform's content. German unification acted simply as a catalyst rather than the cause prompting union reform. German unions can only retain their prominent economic and social position if they promote genuine democratic reform within their ranks. Otherwise unions will never attract employees from the high technology and service sectors that are essential to the union movement's survival in the coming century. German unions should also resist the temptation to take on all of the problems plaguing German society. They must instead concentrate on the essential tasks of all labour movements: discerning the ever‐changing wants of today's increasingly heterogeneous work force and fighting with employers and governments to obtain them. 相似文献

We report on the mitochondrial DNA (mtDNA) analysis of the supposed remains of Francesco Petrarca exhumed in November 2003, from the S. Maria Assunta church, in Arquà Padua (Italy) where he died in 1374. The optimal preservation of the remains allowed the retrieval of sufficient mtDNA for genetic analysis. DNA was extracted from a rib and a tooth and mtDNA sequences were determined in multiple clones using the strictest criteria currently available for validation of ancient DNA sequences, including independent replication. MtDNA sequences from the tooth and rib were not identical, suggesting that they belonged to different individuals. Indeed, molecular gender determination showed that the postcranial remains belonged to a male while the skull belonged to a female. Historical records indicated that the remains were violated in 1630, possibly by thieves. These results are consistent with morphological investigations and confirm the importance of integrating molecular and morphological approaches in investigating historical remains. 相似文献

Judging the validity of a disputed will is complex; however, one of the main issues is what the mental status of the testator was at the time of the will. If the will is handwritten, a handwriting analysis can provide information on the mental status of the testator. We tested how two writing parameters (the "writing score," a novel evaluation scale that we previously described, and the percentage of spelling mistakes) are capable to identify cognitively impaired persons. These parameters are especially helpful because they can be used to evaluate the mental status of a deceased person. We found a significant correlation between either parameter and established scales of neuropsychological evaluation (Mini Mental State Examination and Milan Overall Dementia Assessment scale). Specifically, a poor score on either parameter reliably identified a compromised cognitive status. These may represent helpful additions to existing techniques in posthumously identifying persons with severe cognitive impairment. 相似文献

This study explored risk factors for adolescent dating aggression (ADA) among Brazilian street youth. Forty-three adolescents, between the ages of 13 and 17 years, were recruited at services centers in Porto Alegre, Brazil. Simultaneous multiple regression revealed that ADA was significantly predicted by adolescent dating victimization (ADV), and that this relationship was moderated by peer involvement in dating aggression. Results also revealed that peer involvement in dating aggression did not significantly predict ADA. These findings suggested that having peers who are involved in dating aggression exacerbates the effects of dating victimization on ADA among Brazilian street youth. However, ADV might be a stronger risk factor for dating aggression in this population, because when controlling for the effects of victimization in dating conflicts peer abuse toward romantic partners did not uniquely contribute to ADA. 相似文献
