Recent advances in nanotechnology have prompted the need for tools to accurately and non-invasively manipulate individual nano-objects. Among the possible strategies, optical forces have been widely used to enable nano-optical tweezers capable of trapping or moving a specimen with unprecedented accuracy. Here, we propose an architecture consisting of a nanotip excited with a plasmonic vortex enabling effective dynamic control of nanoparticles in three dimensions. The structure illuminated by a beam with angular momentum can generate an optical field which can be used to manipulate single dielectric nanoparticles. We demonstrate that it’s possible to stably trap or push the particle from specific points, thus enabling a new platform for nanoparticle manipulation. [less ▲]

OBJECTIVES: We aimed to develop the transaddiction craving triggers questionnaire (TCTQ), which assesses the propensity of specific situations and contexts to trigger craving and to test its psychometric properties in alcohol use disorder (AUD). METHODS: This study included a sample of 111 AUD outpatients. We performed exploratory factor analysis (EFA) and calculated item-dimension correlations. Internal consistency was measured with Cronbach's alpha coefficient. Construct validity was assessed through Spearman correlations with craving, emotional symptoms, impulsivity, mindfulness, and drinking characteristics. RESULTS: The EFA suggested a 3-factor solution: unpleasant affect, pleasant affect, and cues and related thoughts. Cronbach's coefficient alpha ranged from .80 to .95 for the three factors and the total score. Weak positive correlations were identified between the TCTQ and drinking outcomes, and moderate correlation were found between the TCTQ and craving strength, impulsivity, anxiety, depression, and impact of alcohol on quality of life. CONCLUSIONS: The 3-factor structure is congruent with the well-established propensity of emotions and cues to trigger craving. Construct validity is supported by close relations between the TCTQ and psychological well-being rather than between the TCTQ and drinking behaviors. Longitudinal validation is warranted to assess sensitivity to change of the TCTQ and to explore its psychometric properties in other addictive disorders. [less ▲]

Inclusive education has become a leading theme internationally over the past several decades, as it addresses key issues, often controversial, of exclusion/inclusion, learning opportunities, and educational equality and justice. Among international organizations as well as supranational governments, we find an increasing emphasis on recognizing diversity and enabling education for all. This is visible in the Salamanca Declaration (1994), the overall “education-for-all” agenda, the Sustainable Developments Goals (e.g., Education, SDG 4), and the worldwide ratification of the UN Convention on the Rights of People with Disabilities (e.g., Article 24 on Education), which mandates among state parties the establishment of an inclusive education system across levels, from early childhood to lifelong learning. This frame of reference is not only significant in terms of definitions and contents but also in the context of the strengthening of world society. The world societal level is not the same as what occurs in the relations between nation states, as important as such learning in policies and practices may be but extends beyond. This is evident in the definition of “inclusion” that has become significant internationally as a category signifying attempts to guarantee access and participation in different levels of education systems, but one that has contrasting and divergent understandings, implications, and implementation consequences between national and local contexts. The goal of participation that follows normatively and legally from such understandings of inclusion, is recontextualized differently, sometimes even paradoxically, when in fact segregated and separate settings are extended under the banner of inclusion. In Germany, for example, despite inclusion discourse flowing from such international agendas that focus on processes of integration and participation, the structures, cultures, and practices that disadvantage and disable continue to exist or even become strengthened. Even if the myriad dimensions of diversity are increasingly discussed and intersectional approaches become more important, the emphasis on difference of disability or “special educational needs” continues. In educational research, numerous publications have delineated the establishment of inclusive education from diverse perspectives. Over the past decade in particular, this has occurred in relation to the UN CRPD, which also implies a connection to the world society-frame; however, theorization and in-depth empirical analyses are lacking to explain more recent developments on multiple levels. Even for nation-states, few systematic and comparative studies have analyzed the diverse forms of inclusive education in different contexts. The consequence has been a divergence between the national discourses of inclusive education, for example, in the German-speaking countries, that remain focused on special educational needs, and the more global discourse that understands inclusive education in human rights terms and a key developmental process in democracies. Although some recent comparative research projects and dissertations provide insights into specific country contexts, a more comprehensive publication that collects such research results of international inclusive educational research has been lacking. Furthermore, the opportunity presents itself to extend the dialogue through a world society perspective on inclusion to reflect global inequalities via integrating case studies from the Global South. International and intercultural perspectives enable the investigation of structures, cultures and practices of different countries to the crucial comparison of educational processes. This is especially necessary in the case of inclusive education, whether as a source of inspiration, a reflexive critique of taken-for-grantedness or as a means to identify disparities and social inequalities. Thus, in several dozen chapters, the Handbook Inclusion International presents diverse global, national, and local perspectives on inclusive education. [less ▲]

We examine the complex relationship between money and happiness. We find that both permanent income and wealth are better predictors of life satisfaction than current income and wealth. They matter not only in absolute terms but also in comparative terms. However, their relative impacts differ. The first exerts a comparison effect – the higher the permanent income of the reference group, the lower life satisfaction – the second exerts an information effect – the higher the permanent wealth of the reference group, the higher life satisfaction. We also show that negative transitory shocks to income reduce life satisfaction while transitory shocks to wealth have no effect. Lastly, we analyse the effects of their components and find that not all of them predict life satisfaction: permanent taxes do not matter, while only the value of permanent real estate, financial and business assets do. Finally, we use quantile regression and analyse to what extent our results vary along the well-being distribution, finding the impacts to be larger at lower levels of life satisfaction. [less ▲]

High quality attenuated intracellular action potentials from large cell networks can be recorded on multi-electrode arrays by means of 3D vertical nanopillars using electrical pulses. However, most of the techniques require complex 3D nanostructures that prevent the straightforward translation into marketable products and the wide adoption in the scientific community. Moreover, 3D nanostructures are often delicate objects that cannot sustain several harsh use/cleaning cycles. On the contrary, laser optoacoustic poration allows the recording of action potentials on planar nanoporous electrodes made of noble metals. However, these constraints of the electrode material and morphology may also hinder the full exploitation of this methodology. Here, we show that optoacoustic poration is also very effective for porating cells on a large family of MEA electrode configurations, including robust electrodes made of nanoporous titanium nitride or disordered fractal-like gold nanostructures. This enables the recording of high quality cardiac action potentials in combination with optoacoustic poration, providing thus attenuated intracellular recordings on various already commercial devices used by a significant part of the research and industrial communities.

Purpose of Review Along with the expansion of on-demand viewing technology, the practice of binge-watching (i.e., watching multiple episodes of TV series back-to-back) has recently gained increasing research interest, given its potential harmfulness and presumed addictive characteristics. The present article provides the first systematic review of the evidence regarding this increasingly widespread behavior. Recent Findings The results of this systematic review (including 24 studies and 17,545 participants) show that binge-watching remains an ill-defined construct as no consensus exists on its operationalization and measurement. Although such methodological disparities across studies hinder the comparability of results, the preliminary findings gathered here mainly point to the heterogeneous nature of binge-watching which covers at least two distinct realities, i.e., high but non-harmful engagement and problematic involvement in TV series watching. Summary In these early stages of research, there is a major need for more consistency and harmonization of constructs and their operationalizations to move forward in the understanding of binge-watching. Just as important, future research should maintain the distinction between high and problematic involvement in binge-watching to avoid overpathologizing this common behavior [less ▲]

This paper examines the effect of risk disclosure on firm operational efficiency using a unique database of nonfinancial, and non-utility French firms belonging to the SBF 120 index over the period 2007–2015. In a first step, we use a data envelopment analysis output-oriented variable returns to scale model to determine firm operational efficiency scores based on one output (i.e., sales revenue) and three inputs (i.e., net property, plant, and equipment; cost of goods sold; and selling, general, and administrative costs). These scores are used in a second step to estimate the effect of risk disclosure on operational efficiency after controlling for a set of other factors. The empirical results show a statistically significant positive relation between risk disclosure and operational efficiency, suggesting that firms tend to be relatively more efficient when they disclose more about their risk exposure. Overall, we provide evidence that firms with greater risk disclosure are seen by stakeholders as more credible and trustworthy, leading them to conduct better transactions and, consequently, to improve their operational efficiency. This result is consistent with the notion that stakeholders perceive transparent firms positively, particularly those revealing bad news. [less ▲]

Cyber-Physical Systems are usually subject to dependability requirements such as safety and reliability constraints. Over the last 50 years, a body of efficient fault-tolerance mechanisms has been devised to handle faults occurring at run-time. However, properly implementing those mechanisms is a time-consuming task that requires a great deal of know-how. In this paper, we propose a general framework which allows system designers to decouple functional and non-functional concerns, and express non- functional properties at design time using domain-specific languages. In the spirit of generative programming, functional models are then automatically “augmented” with dependability mechanisms. Importantly, the real-time behavior of the initial models in terms of sampling times and meeting deadlines is preserved. The practicality of the approach is demonstrated with the automated implementation of one prominent software fault-tolerance pattern, namely N-Version Programming, in the CPAL model-driven engineering workflow.

The key novelty of this contribution is a dedicated technique to e fficiently determine the distance (gap) function between parallel or almost parallel beams with circular and elliptical cross-sections. The technique consists of parametrizing the surfaces of the two beams in contact, fixing a point on the centroid line of one of the beams and searching for a constrained minimum distance between the surfaces (two variants are investigated). The resulting unilateral (frictionless) contact condition is then enforced with the Penalty method, which introduces compliance to the, otherwise rigid, beams' cross-sections. Two contact integration schemes are considered: the conventional slave-master approach (which is biased as the contact virtual work is only integrated over the slave surface) and the so-called two-half-pass approach (which is unbiased as the contact virtual work is integrated over the two contacting surfaces). Details of the finite element formulation which is suitably implemented using Automatic Di fferentiation techniques are presented. A set of numerical experiments shows the overall performance of the framework and allows a quantitative comparison of the investigated variants. [less ▲]
