This volume explores and critiques one of the most dynamic terrains of political theory sometimes referred to as 'Autonomist Marxism' or post-Operaismo. Taking three divergent manifestations of Autonomist Marxism found in the works of John Holloway, Antonio Negri and Paul Virno, David Eden examines how each approach questions the nature of class and contemporary capitalism and how they extrapolate politics.

Abstract. Background and Aims: Given the effectiveness of the National Confidential Inquiry into Suicide and Homicide by People with Mental Illness (NCI) in the UK, the present study evaluated this approach in Southwestern Ontario. A systematic confidential examination of suicides in Ontario was developed to guide quality improvement of services and suicide prevention. Method: A 3-year case series of consecutive suicides in Southwestern Ontario identified by the Office of the Chief Coroner was compiled. Clinicians who provided care to suicide decedents completed an online confidential suicide questionnaire offered through a secured portal. Results: A total of 476 suicide cases were analyzed. In all, 270 invitations to clinicians were sent, 237 (87.8%) responded to the invitation and 187 (69.3%) completed the online questionnaire. The majority of the suicide decedents (54.6%, n = 260), were between the ages of 40 and 64 (x = 47.2, SD = 17.1), White (91.4%, n = 416), single (34.2%, n = 439), and male (74.4%, n = 476). Of the 86 cases of self-poisoning, prescription medications were used in 66.3%. Almost two thirds of decedents visited the clinician in the month prior to their death. Limitations: The results of the survey were drawn from suicides in Southwestern Ontario and generalizing these findings should be done with caution. Conclusion: This study highlights (a) the value of the clinicians' survey to identify gaps in clinical services and (b) the necessity of improvements in suicide risk assessment/management and restriction of prescription medications.

Prestellar cores are self-gravitating dense and cold structures within molecular clouds where future stars are born. They are expected, at the stage of transitioning to the protostellar phase, to harbor centrally concentrated dense (sub)structures that will seed the formation of a new star or the binary/multiple stellar systems. Characterizing this critical stage of evolution is key to our understanding of star formation. In this work, we report the detection of high-density (sub)structures on the thousand-astronomical-unit (au) scale in a sample of dense prestellar cores. Through our recent ALMA observations toward the Orion Planck Galactic Cold Clumps, we have found five extremely dense prestellar cores, which have centrally concentrated regions of similar to 2000 au in size, and several 10(7) cm(-3) in average density. Masses of these centrally dense regions are in the range of 0.30 to 6.89 M. For the first time, our higher resolution observations (0.8 '' similar to 320 au) further reveal that one of the cores shows clear signatures of fragmentation; such individual substructures/fragments have sizes of 800-1700 au, masses of 0.08 to 0.84 M, densities of 2 - 8 x 10(7) cm(-3), and separations of similar to 1200 au. The substructures are massive enough (greater than or similar to 0.1 M) to form young stellar objects and are likely examples of the earliest stage of stellar embryos that can lead to widely (similar to 1200 au) separated multiple systems. ; Ministry of Science and Technology, China 108-2112-M-001-048- 108-2112-M-001-052- international partnership program of the Chinese Academy of Sciences 114231KYSB20200009 National Natural Science Foundation of China (NSFC) 12073061 Shanghai Pujiang Program 20PJ1415500 ANID AFB 170002 AFB-170002 National Natural Science Foundation of China (NSFC) U1631237 NRC Canada Natural Sciences and Engineering Research Council of Canada (NSERC) Spanish Government AYA2017-88754-P State Agency for Research of the Spanish Ministry of Science and Innovation through the "Unit of Excellence Maria de Maeztu 2020-2023" award CEX2019-000918-M Basic Science Research Program through the National Research Foundation of Korea (NRF) - Ministry of Education, Science and Technology NRF-2019R1A2C1010851 National Science Foundation (NSF) AST-1715876 National Natural Science Foundation of China (NSFC) 11911530226 11725313 11873086 Ministry of Education, Culture, Sports, Science and Technology, Japan (MEXT) Japan Society for the Promotion of Science Grants-in-Aid for Scientific Research (KAKENHI) 20H05645 Yunnan Province of China 2017HC018 Chinese Academy of Sciences MoST 108-2112-M-001-017 MoST 109-2112-M-001-023 ; Versión publicada - versión final del editor
