From comparative to international genocide studies: the international production of genocide in 20th-century Europe

Genocide is widely seen as a phenomenon of domestic politics, which becomes of international significance because it offends against international law. Hence there are as yet inadequate International Relations analyses of the production of genocide. This article challenges the idea of the domestic genesis of genocide, and critiques the corresponding approach of ‘comparative genocide studies’ which is dominant in the field. It analyses the emergence of more fruitful ‘relational’ and ‘international’ approaches in critical genocide studies, while identifying the limitations of their accounts of the ‘international system’. As first steps towards an adequate international account, the article then explores questions of the international meaning and construction of genocidal relations, and of international relations as the context of genocide. It argues for a historical and sociological approach to the international relations of genocide, and examines 20th-century European genocide in this light. Arguing for a broader conception of this historical experience than is suggested by an exclusive focus on the Holocaust, the article offers an interpretation of genocide as increasingly endemic and systemic in international relations in the first half of the century. It concludes by arguing that this account offers a starting point, but not a model, for analyses of genocide in global international relations in the 21st centur

Heart Rate Variability and Cardio-respiratory Coupling During Sleep in Patients Prior to Bariatric Surgery

Obesity is associated with increased cardiac risk of morbidly and mortality and for the development and progression of obstructive sleep apnea (OSA). Severity of obesity negatively affects the heart rate variability (HRV) in patients with indication for bariatric surgery (BS). The purpose of this study is to determine if the severity of obesity alters the autonomic cardiac regulation and the cardio-respiratory coupling during sleep using spectral analysis of HRV and respiration variability signals (RS) in patients prior to BS. Twenty-nine consecutive preoperative BS and ten subjects (controls) underwent polysomnography. The spectral and cross-spectral parameters of the HRV and RS were computed during different sleep stages (SS). Spectral analysis of the HRV and RV indicated lower respiration regularity during sleep and a lower HRV in obese patients (OP) during all SS when compared with controls (p < 0.05). Severely (SO) and super-obese patients (SOP) presented lower values of low frequency/high frequency (LF/HF) ratio and LF power during REM sleep and higher HF power (p < 0.05), while morbidly obese (MO) patients presented lower LF/HF ratio and LF power in SS-S2 and higher HF power when compared to controls (p < 0.05). The cross-spectral parameters showed that SOP presented lower percentage of tachogram power coherent with respiration in SS-S3 when compared to controls (p < 0.05). Patients prior to BS presented altered HRV and RV in all SS. SO, MO, and SOP presented altered cardio-respiratory coupling during sleep, and these alterations are related with severity of obesity and OSA parameters
