BACKGROUND: The U.S. National Institutes of Mental Health Research Domain Criteria (RDoC) seek to stimulate research into biologically validated neuropsychological dimensions across mental illness symptoms and diagnoses. The RDoC framework comprises 39 functional constructs designed to be revised and refined, with the overall goal to improve diagnostic validity and treatments. This study aimed to reach a consensus among experts in the addiction field on the 'primary' RDoC constructs most relevant to substance and behavioural addictions. METHODS: Forty-four addiction experts were recruited from Australia, Asia, Europe and the Americas. The Delphi technique was used to determine a consensus as to the degree of importance of each construct in understanding the essential dimensions underpinning addictive behaviours. Expert opinions were canvassed online over three rounds (97% completion rate), with each consecutive round offering feedback for experts to review their opinions. RESULTS: Seven constructs were endorsed by >/=80% of experts as 'primary' to the understanding of addictive behaviour: five from the Positive Valence System (Reward Valuation, Expectancy, Action Selection, Reward Learning, Habit); one from the Cognitive Control System (Response Selection/Inhibition); and one expert-initiated construct (Compulsivity). These constructs were rated to be differentially related to stages of the addiction cycle, with some more closely linked to addiction onset, and others more to chronicity. Experts agreed that these neuropsychological dimensions apply across a range of addictions. CONCLUSIONS: The study offers a novel and neuropsychologically informed theoretical framework, as well as a cogent step forward to test transdiagnostic concepts in addiction research, with direct implications for assessment, diagnosis, staging of disorder, and treatment.

This contribution will give a brief overview of EU legislation encouraging self-regulation, such as codes of conduct, communications and recommendations and propose an alternative approach towards fighting illegal content on online platforms, which ventures squarely into co-regulation. There is no formal and straightforward definition on what constitutes illegal hate speech. However, hate speech might be classified as targeting minority groups in a way that promotes violence or social disorder and hatred. The use of social media and online platforms to spread illegal content and hate speech has increased progressively during recent years, as content may be disseminated anonymously and further shared by other users. Therefore, the timely removal or blocking of access to illegal content is essential to limit the wider dissemination and harm of individuals targeted by hate speech. The prominent role of online platforms in revolutionizing modern communication and as influencers of the public opinion has increasingly come to the attention of policy makers. Since online platforms provide an important stage for phenomena such as ‘fake news’, ‘hate speech’ or ‘disinformation’, the pressure to take more responsibility over content hosted by them has grown. The EU Commission took action via several attempts to set certain rules for online intermediaries, mostly relying on non-binding agreements, often in the form of self-regulatory measures, such as codes of conduct, guidelines and recommendations. These measures have raised concerns regarding possible limitations of Freedom of Expression, because they require online platforms to adjudicate on the legality of content, often by relying on automated systems. Meanwhile decisions over the unlawfulness of hate speech and “disinformation” are often notoriously difficult. The deployment of algorithms to analyse the content generated on platforms, such as recognition and filtering technologies, bear risks and pitfalls of automated compliance solutions. Although the use of algorithms to monitor content online still happens based on the “human-in-the-loop principle”, the diligence and efficiency with which illegal content can be reviewed is also dependent on the financial capacity and resources of each company. In addition, these privatized removal procedures maybe influenced by commercial interests and lack effective appeals mechanisms. All these issues throw up serious questions about the democratic legitimacy of self-regulatory removal procedures An alternative solution, proposed in this article, would require platforms to apply a risk-based approach to preventing and removing illegal content. The norms and standards of such an approach would be based on duty of care and be subject to regulatory oversight. It is suggested that the current self-regulatory proposals be replaced by co-regulatory solutions. [less ▲]

We discuss Bayesian inference for the identi cation of elastoplastic material parameters. In addition to errors in the stress measurements, which are commonly considered, we furthermore consider errors in the strain measurements. Since a difference between the model and the experimental data may still be present if the data is not contaminated by noise, we also incorporate the possible error of the model itself. The three formulations to describe model uncertainty in this contribution are: (1) a random variable which is taken from a normal distribution with constant parameters, (2) a random variable which is taken from a normal distribution with an input-dependent mean, and (3) a Gaussian random process with a stationary covariance function. Our results show that incorporating model uncertainty often, but not always, improves the results. If the error in the strain is considered as well, the results improve even more. [less ▲]

Numerous materials are essentially structures of discrete fibres, yarns or struts. Considering these materials at their discrete scale, one may distinguish two types of intrinsic randomness that affect the structural behaviours of these discrete structures: geometrical randomness and material randomness. Identifying the material randomness is an experimentally demanding task, because many small fibres, yarns or struts need to be tested, which are not easy to handle. To avoid the testing of hundreds of constituents, this contribution proposes an identification approach that only requires a few dozen of constituents to be tested (we use twenty to be exact). The identification approach is applied to articially generated measurements, so that the identified values can be compared to the true values. Another question this contribution aims to answer is how precise the material randomness needs to be identified, if the geometrical randomness will also influence the macroscale behaviour of these discrete networks. We therefore also study the effect of the identified material randomness to that of the actual material randomness for three types of structures; each with an increasing level of geometrical randomness.

Synthetic opioids (SO) are a major risk for public health across the world. These drugs can be divided into 2 categories, pharmaceutical and non-pharmaceutical fentanyls. A new generation of SO has emerged on the drug market since 2010. North America is currently facing an opioid epidemic of morbi-mortality, caused by over-prescription of opioids, illegally diverted prescribed medicines, the increasing use of heroin, is and the emergence of SO. Furthermore, this opioid crisis is also seen in Europe. SO are new psychoactive substances characterized by different feature such as easy availability on the Internet, low price, purity, legality, and lack of detection in laboratory tests. They have not been approved or are not recommended for human use. Opioid misuse is associated with somatic and psychiatric complications. For many substances, limited pharmacological information is available, increasing the risk of harmful adverse events. Health actors and the general population need to be clearly informed of the potential risks and consequences of the diffusion and use of SO. [less ▲]

This paper investigates whether long-term finance affects firm entry worldwide. We construct a new database on short-term and long-term credit provided by commercial banks to the private sector in 85 countries over the period 1995-2014. We then analyze whether differences in entrepreneurship are related to the provision of short-term and long-term bank credit. Data on entrepreneurship are extracted from two frequently used databases: the Global Entrepreneurship Monitoring dataset and the Entrepreneurship Database, each of which captures different aspects of firm creation. Econometric results indicate that long-term credit does not stimulate firm entry. By contrast, we find that short-term credit is positively related to firm creation, from birth to registration. Controlling for potential endogeneity by implementing an instrumental variables approach does not affect our conclusions. Our findings suggest that better provision of short-term credit allows entrepreneurs to apply for formal loan instead of having to rely exclusively on informal loans or internal funds. The absence of impact of long-term loans can be explained by the difficulty entrepreneurs face in getting access to long-term credit. [less ▲]

We introduce the notion of almost commutative Q-algebras and demonstrate how the derived bracket formalism of Kosmann-Schwarzbach generalises to this setting. In particular, we construct ‘almost commutative Lie algebroids’ following Vaintrob’s Q-manifold understanding of classical Lie algebroids. We show that the basic tenets of the theory of Lie algebroids carry over verbatim to the almost commutative world. [less ▲]

This paper studies experimentally the behaviour of circular FRP-steel-confined columns subjected to reversed cyclic loads. The influence of main structural factors on the cyclic behaviour of the columns is discussed. Test results show the outstanding seismic performance of FRP-steel confined reinforced concrete (RC) and steel-reinforced concrete (SRC) column. The lateral confinement effectiveness of FRP materials is verified in the steel tube confined RC columns. A simplified finite element method (FEM) model supported by OpenSees is developed to simulate the experimental results of the test columns. Based on the proposed FEM model, a parametric analysis is conducted for investigating the effects of several main factors on the reversed cyclic behaviour of GFRP-steel confined RC columns. Based on the test and numerical analyses, the study discusses the influence of variables such as the lateral confinement on the plastic hinge region and peak drift ratio of the studied concrete columns under reversed cyclic loads. Results indicate that the lateral confinement significantly affects the height of plastic hinge region of circular confined columns without H-steel. Based on the analysies of test data from the study and literature, the paper suggests a simple model to predict the peak drift ratio of the confined RC columns. [less ▲]

Brian Leiter (2016) throws down two gauntlets to philosophers engaged in dialogue with the broader public. If, with the first, public philosophers recognize that they cannot offer substantive answers but only sophisticated method, they nevertheless fail to realize that said method does not resonate with the very public whom they purport to help. For, with the second, that method does not engage the emotivist and tribalist cast of contemporary public discourse: emotivist because a person’s moral and political beliefs are a function of emotional attitudes or affective responses for which she adduces reasons post hoc; tribalist because the person tracks not the inferential relation between beliefs but her similarity with interlocutors. In order to understand the full extent of this critique, it is necessary, first, to parse strands of public philosophy, distinct discursive sites, and pictures of philosophical practice and, then, to probe the critique’s empirical groundedness and intended scope. These elements in place, it is then possible to sketch public philosophy reconceived along Leiter’s lines as equal part rigor and rhetoric. That sketch may be somewhat filled out through two tactics employed in Jeffrey Stout’s (2004, 2010) work. These form part of a toolkit for philosophical dialogue whereby philosophers get a discursive grip on non-discursive factors underlying public discourse and push back on Leiter's dilemma. [less ▲]

Conventional wisdom holds that building democracy takes time. Deliberative democracy will likely prove no exception. To that end, this chapter will explore one possible path towards more deliberative institutions and decision-making in the form of Gastil and Wright’s proposal for a Sortition Chamber. Our thesis is that deliberative innovations, notably a sortition chamber, require a gradualist approach to implementation. While other authors in this volume may take for granted that some form of sortition chamber will be institutionalized and focus instead on design questions, we probe the necessary conditions preceding institutionalization. To support this thesis, we shall make an argument comprising four main claims. 1.) Sortition is a promising deliberative innovation. 2.) A strong, unaccountable deliberative device like sortition may delegitimize citizen deliberation and future deliberative innovations, in particular a sortition chamber. 3.) A weaker deliberative device like citizens’ consultation is effective though often blocked by a lack of institutional footing. 4.) Citizens’ consultation, once proven to be effective and regular, opens one path towards enhanced deliberative innovations like the sortition chamber. Claim 1.) will not be developed here beyond the point that a sortition chamber’s “hybrid legitimacy” may allow it to overcome critiques addressed to one-shot, single-issue consultative or 1 empowered mini-publics which may lack institutional footing1. Such mini-publics face multiple challenges: significant social or political uptake, electoral accountability, capture by interests, political redundancy, representativeness, biases, frames2. If a sortition chamber prima facie meets or precludes these different critiques, it represents a striking contribution to democratic innovations beyond mini-publics. That said, we must work out claims 2.), 3.) and 4.) in individual sections below. While examples in 3.) and 4.) will mainly be drawn from the European Union, we maintain that this argument is broadly applicable at local, regional national and transnational levels. We argue that, if institutionalizing consultative mini-publics is desirable and feasible at the EU level, it will be all the more so at other levels throughout the decision-making process’ different stages.
