An international consensus for assessing internet gaming disorder using the new DSM-5 approach

Abstract: Aims For the first time, the Diagnostic and Statistical Manual for Mental Disorders (DSM-5) introduces non- substance addictions as psychiatric diagnoses. The aims of this paper are to (i) present the main controversies surrounding the decision to include internet gaming disorder, but not internet addiction more globally, as a non-substance addiction in the research appendix of the DSM-5, and (ii) discuss the meaning behind the DSM-5 criteria for internet gaming disorder. The paper also proposes a common method for assessing internet gaming disorder. Although the need for common diagnostic criteria is not debated, the existence of multiple instruments reflect the divergence of opinions in the field regarding how best to diagnose this condition. Methods We convened international experts from European, North and South American, Asian and Australasian countries to discuss and achieve consensus about assessing internet gaming disorder as defined within DSM-5. Results We describe the intended meaning behind each of the nine DSM-5 criteria for internet gaming disorder and present a single item that best reflects each criterion, translated into the 10 main languages of countries in which research on this condition has been conducted. Conclusions Using results from this cross-cultural collaboration, we outline important research directions for understanding and assessing internet gaming disorder. As this field moves forward, it is critical that researchers and clinicians around the world begin to apply a common methodology; this report is the first to achieve an international consensus related to the assessment of internet gaming disorder.

Letter of intent for KM3NeT 2.0

Abstract: The main objectives of the KM3NeT Collaboration are (i) the discovery and subsequent observation of high-energy neutrino sources in the Universe and (ii) the determination of the mass hierarchy of neutrinos. These objectives are strongly motivated by two recent important discoveries, namely: (1) the high-energy astrophysical neutrino signal reported by IceCube and (2) the sizable contribution of electron neutrinos to the third neutrino mass eigenstate as reported by Daya Bay, Reno and others. To meet these objectives, the KM3NeT Collaboration plans to build a new Research Infrastructure consisting of a network of deep-sea neutrino telescopes in the Mediterranean Sea. A phased and distributed implementation is pursued which maximises the access to regional funds, the availability of human resources and the synergistic opportunities for the Earth and sea sciences community. Three suitable deep-sea sites are selected, namely off-shore Toulon (France), Capo Passero (Sicily, Italy) and Pylos (Peloponnese, Greece). The infrastructure will consist of three so-called building blocks. A building block comprises 115 strings, each string comprises 18 optical modules and each optical module comprises 31 photo-multiplier tubes. Each building block thus constitutes a three-dimensional array of photo sensors that can be used to detect the Cherenkov light produced by relativistic particles emerging from neutrino interactions. Two building blocks will be sparsely configured to fully explore the IceCube signal with similar instrumented volume, different methodology, improved resolution and complementary field of view, including the galactic plane. One building block will be densely configured to precisely measure atmospheric neutrino oscillations.

Policy without polity? Policy analysis and the institutional void

Abstract: How should policy analysis respond to the changing context of policy making? This article examines three aspects of policy analysis in this changing context: polity, knowledge and intervention. It argues that policy making now often takes place in an ‘institutional void’ where there are no generally accepted rules and norms according to which politics is to be conducted and policy measures are to be agreed upon. More than before, solutions for pressing problems transgress the sovereignty of specific polities. Furthermore, the role of knowledge changes as the relationship between science and society has changed: scientific expertise is now negotiated rather than simply accepted. And, with the weakening of the state, it is far less obvious that the government is the sole actor to intervene in policy making. This article calls for a reconsideration of the analysis of policy making in the light of this changing context. Based on a contextual perspective it calls for a revitalization of the commitments of Harold Lasswell toward a policy science of democracy by proposing a new ‘deliberative’ policy analysis.
