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 ▲]

Background: Impulsivity is a multidimensional construct playing a pervasive role in psychiatry and neuropsychology. Lynam et al. (2006) have developed the 59-item UPPS-P Impulsive Behavior Scale, which assesses five distinct impulsivity dimensions: positive urgency, negative urgency, lack of perseverance, lack of premeditation, and sensation seeking. The short, 20-item version of the UPPS-P (SUPPS-P; Billieux et al. 2012) has been developed and adapted into several languages, including English, French, Italian, Spanish, and Arabic. The aim of the present study was to test four theoretical models of the SUPPS-P in a large sample of Hungarian adults. Methods: A total of 15,703 participants (64.76% male; Mage = 33.42 years, SD = 11.06) completed the SUPPS-P using an online questionnaire. Results: Confirmatory factor analyses corroborated the first-order five-factor model of impulsivity and a hierarchical model representing three higher-order constructs (urgency, lack of conscientiousness, sensation seeking), whereas the one-factor and three-factor model were not supported. The factor structure of the SUPPS-P preserved the original, theory-driven structure of the UPPS-P model and this instrument demonstrated good internal consistency. Hypersexual behavior consequences were positively associated with most SUPPS-P components, thus criterion validity was also supported. Conclusion: The SUPPS-P had strong psychometric properties that reflected the theoretical structure of the original UPPS-P model, thus it constitutes a theoretically grounded and time saving multidimensional instrument for assessing impulsivity.

A recent paper by Zamariola and colleagues is widely cited as an authority on the invalidity of the Heartbeat Counting Task as a measure of interoceptive accuracy. Given the widespread interest in this field, it is essential that papers about methods are conceptually sound. However, only one of the authors' four criticisms appears substantiated - that people count too few heartbeats. Their arguments about "simple bivariate correlations" and their finding that interoceptive accuracy and heart rate correlate, depend on 'spurious correlations' arising from the overlooked point that interoceptive accuracy is a ratio. Moreover, scrutiny of the authors' data shows that their fourth criticism (that interoceptive accuracy is lower on longer trials) is confounded by differences in mean heart rate between trials. We present data from our own labs to refute it. We draw the authors' and editors' attention to these issues and trust that they will reconsider these erroneous conclusions. [less ▲]

Slender constituents are present in many structures and materials. In associated mechanical models, each slender constituent is often described with a beam. Contact between beams is essential to incorporate in mechanical models, but associated contact frameworks are only demonstrated to work for beams with circular cross-sections. Only two studies have shown the ability to treat contact between beams with elliptical cross-sections, but those frameworks are limited to point-wise contact, which narrows their applicability. This contribution presents initial results of a framework for shear-deformable beams with elliptical cross-sections if contact occurs along a line or at an area (instead of at a point). This is achieved by integrating a penalty potential over one of the beams’ surfaces. Simo-Reissner Geometrically Exact Beam (GEB) elements are employed to discretise each beam. As the surface of an assembly of such beam elements is discontinuous, a smoothed surface is introduced to formulate the contact kinematics. This enables the treatment of contact for large sliding displacements and substantial deformations. [less ▲]

Disablement is a complex social phenomenon in contemporary societies, reflected in disability policies oriented towards contrasting paradigms. Fraught with ambivalence, disability raises dilemmas of classification and targeted supports. Paradoxical universalism emphasizes that to achieve universality requires recognizing individual dis/abilities and particularity contextual conditions and barriers that lead to disablement. Myriad aspects of educational and disability policies challenge both conceptualization and realization of universal policies, such as compulsory schooling, with widespread exclusion or segregation prevalent. Tensions between providing supports and ubiquitous stigmatization and separation that results are endemic—particularly evident during life course transitions that imply shifting memberships in institutions and organizations. Young adults’ transitions from school-to-work are fundamentally challenged by contrasting policies, institutional logics, and institutionalized organizations, particularly visible during inter-institutional transitions. Analyzing institutional logics facilitates understanding of the lack of inter-institutional coordination that hinders successful transitions for disabled youth. Examining such challenges in the United States and Switzerland, we compare two cases with liberal labor markets and federal governance structures but also with contrasting education, welfare and employment systems. Whereas lacking inter-institutional coordination negatively impacts disabled young adults in the US, Switzerland’s robust vocational education and training (VET) system, while not a panacea, does provide more coordinated support during transitions from school-to-work. These two countries provide relevant cases to examine ambivalence and contestation around the human right to inclusive education as well as the universality of the right (not) to work. [less ▲]

This study introduced a fatigue-based approach to design and implement an indicator channel into an in-tank hydrogen valve. It was aimed at providing a mean to point out multiple early valve’s damages. To achieve the goal, the study was proposed to handle via three main phases. They included (i) the risk point determinations, (ii) the new valve design and the crack nucleation life estimations, as well as (iii) the simplified crack growth analyses. The obtained results firstly highlighted the construction of the test channel (TC), whose branches were located close to the predicted damage’s sites. The damages could be identified either when a crack reaches the TC (then forms a leakage) or indirectly via the crack propagations’ correlation. The results also pointed out that the TC-implemented valve could perform as similarly as the non-TC one in the non-treated condition. More importantly, this new structure was proved to have a capacity of satisfying the required minimal life of 1.5E5 cycles, depending on the combined uses of the specific material and the pre-treatment, among those considered. In addition, the results emphasized the complexity of the TC that could not be formed by the traditional manufacturing process. Hence, direct metal laser sintering was proposed for the associated prototype and the final TC was issued based on the fundamental requirements of the technique. Finally, it was suggested that practical experiments should essentially be carried out to yield more evidence to support the demonstrated results. [less ▲]

This article explores the application of evolutionary algorithms and agent-oriented programming to solve the problem of searching and monitoring objectives through a fleet of unmanned aerial vehicles. The subproblem of static off-line planning is studied to find initial flight plans for each vehicle in the fleet, using evolutionary algorithms to achieve compromise values between the size of the explored area, the proximity of the vehicles, and the monitoring of points of interest defined in the area. The results obtained in the experimental analysis on representative instances of the surveillance problem indicate that the proposed techniques are capable of computing effective flight plans.

International migration between economically highly developed countries is a central component of global migration flows. Still, surprisingly little is known about the international mobility of the populations of these affluent societies. The aim of the German Emigration and Remigration Panel Study (GERPS) is to collect data to analyse the individual consequences of international migration as well as the consequences for the country of origin. GERPS is based on an origin-based multistage probability sample using the German population registers as a sampling frame. The realised net sample includes more than 11,000 persons who recently moved abroad from Germany and persons returning to Germany after having lived abroad. The study follows a multi-destination country design and allows comparative analyses of migrants and non-migrants who stayed in the country of origin. GERPS is a panel study with at least four waves during a period of at least 24 months. This documentation, however, presents the methodology and the data for the first wave providing the baseline survey. Detailed information is provided to invite external researchers to apply the new data infrastructure to their own research and to disseminate the innovative research design to construct migrant samples.
