Interoceptive accuracy (IAc), i.e. the ability to accurately perceive one’s own bodily signals, is widely assumed to be a trait, although experimental manipulations, such as stress, may affect IAc. We used structural equation modeling to estimate the reliability of IAc, and the proportions of individual differences in IAc, explained by a trait and occasion-specific effects of situation and person-situation interactions. We assessed IAc in 59 healthy participants (40 women, MAge = 23.4 years) on three consecutive measurement occasions, approx. one week apart, in a ‘rest’ and ‘poststress’ condition, using a heartbeat counting and a heartbeat discrimination task. The results show fair temporal stability (intraclass correlation coefficients ≥ 0.38) and good reliability (Mdn = .63; range .49-.83) for both methods. While around 40% of the variance of a single IAc measurement could be explained by a trait, approx. 27% were accounted for by occasion-specific effects of situation and person-situation interaction. These results suggest that IAc measures are relatively consistent and that situations and person-situation interactions impact IAc as measured at a certain point in time. An aggregation across at least two measurements is recommended when using IAc as a trait variable. [less ▲]

The European Semester is an information-driven surveillance system that relies upon budgetary and economic statistics collected from the European Union’s member states and analyzed by the European Commission. This is true for both the Excessive Deficit Procedure (EDP) and the Macroeconomic Imbalance Procedure (MIP). This article employs Principal–Agent theory to analyze the politics of asymmetric information in the EDP and MIP. The study explores how the statistical requirements of the Six-Pack have been enforced by the Commission and the Economic and Financial Affairs Council to strengthen the EDP, even as the statistical integrity of the MIP received less protection. The article examines how the misrepresentation of statistics by Spain’s Autonomous Community of Valencia provoked the first financial sanction in the history of Economic and Monetary Union, as well as the Commission’s unsuccessful efforts to strengthen the reliability of MIP statistics.

This article considers the extent to which foreign investors in Member States of the Economic Community of West African States (ECOWAS) might be able to use the ECOWAS Court of Justice to protect their investments against actions of their host States. It does so taking into account the ECOWAS Supplementary Act on Investments and the jurisprudence of the Court of Justice on, in particular, the extent of its substantive jurisdiction. Although it is not suggested that the Court of Justice would be better forum than an international arbitral tribunal, it is argued that it has considerable advantages over national courts. [less ▲]

Ru has been considered a candidate to replace Cu-based interconnects in VLSI circuits. Here, a methodology is proposed to predict the resistivity of (Ru) interconnects. First, the dependence of the Ru thin film resistivity on the film thickness is modeled by the semiclassical Mayadas-Shatzkes (MS) approach. The fitting parameters thus obtained are then used as input in a modified MS model for nanowires to calculate wire resistivities. Predicted experimental resistivities agreed within about 10%. The results further indicate that grain boundary scattering was the dominant scattering mechanism in scaled Ru interconnects. [less ▲]

Sociology has made significant contributions to the conceptualisation of risk and critique of technical risk analysis. It has, however, unintentionally reinforced the division of labour between the natural/technical and social sciences in risk analysis. This paper argues that the problem with conceptualisations of risk is not a misplaced emphasis on calculation. Rather, it is that we have not adequately dealt with ontological distinctions implicit in both sociological and technical work on risk between material or objective risks and our socially-mediated understandings and interpretations of those risks. While acknowledging that risks are simultaneously social and technical, sociologists have not, in practice, provided the conceptual and methodological tools to apprehend risk in a less dualistic manner. This limits our ability both to analyse actors and processes outside the social domain and to explore the recursive relationships between risk calculus, social action and the material outcomes of risk. In response, this paper develops a material-semiotic conceptualisation of risk and provides an assessment of its relevance to more sociologically-informed risk governance. It introduces the ideas of co-constitution, emergent entities and enactment as instruments for reconciling the material and social worlds in a sociological study of risk. It further illustrates the application of a material-semiotic approach using these concepts in the nuclear industry. In deconstructing social-material dualisms in the sociology of risk, this paper argues that a material-semiotic conceptualisation of risk enables both technical and social perspectives on risk not only to co-exist but to collaborate, widening the scope for interdisciplinary research.

The Research Center for Autonomous Road Vehicles (RECAR) was founded in 2015 upon the initiative of the Faculty of Transportation Engineering and Vehicle Engineering of Budapest University of Technology and Economics. The research center is supported by industrial partners and other academic partners targeting research and educational purposes. In complement to this project, the construction of a new automotive test track is also under development especially for autonomous road vehicle testing serving as automotive proving ground in Zalaegerszeg, Hungary. Accordingly, an intensive research has been started in RECAR center in the field of autonomous vehicle technology. The paper’s goal is to share the main practical and methodological experiences with the scientific audience as well as the industrial sector. Based on the initial research actions we intend to enlighten the upcoming research challenges of driverless vehicles and automated intelligent transport system. Basically, three main topics are concerned. Firstly, the main issues concerning autonomous vehicle research are summarized. Secondly, the requirements for autonomous test track design are concluded. Thirdly, the legal questions that emerge with the appearance of driverless vehicles are investigated, especially concerning liability. [less ▲]

Data is a modern form of wealth in the digital world, and massive amounts of data circulate in cloud environments. While this enormously facilitates the sharing of information, both for personal and professional purposes, it also introduces some critical problems concerning the ownership of the information. Data is an intangible good that is stored in large data warehouses, where the hardware architectures and software programs running the cloud services coexist with the data of many users. This context calls for a twofold protection: on one side, the cloud is made up of hardware and software that constitute the business assets of the service provider (property of the cloud); on the other side, there is a definite need to ensure that users retain control over their data (property in the cloud). The law grants protection to both sides under several perspectives, but the result is a complex mix of interwoven regimes, further complicated by the intrinsically international nature of cloud computing that clashes with the typical diversity of national laws. As the business model based on cloud computing grows, public bodies, and in particular the European Union, are striving to find solutions to properly regulate the future economy, either by introducing new laws, or by finding the best ways to apply existing principles.

System testing plays a crucial role in safety-critical domains, e.g., automotive, where system test cases are used to demonstrate the compliance of software with its functional and safety requirements. Unfortunately, since requirements are typically written in natural language, significant engineering effort is required to derive test cases from requirements. In such a context, automated support for generating system test cases from requirements specifications written in natural language would be highly beneficial. Unfortunately, existing approaches have limited applicability. For example, some of them require that software engineers provide formal specifications that capture some of the software behavior described using natural language. The effort needed to define such specifications is usually a significant deterrent for software developers. This paper proposes an approach, OCLgen, which largely automates the generation of the additional formal specifications required by an existing test generation approach named UMTG. More specifically, OCLgen relies on semantic analysis techniques to automatically derive the pre- and post-conditions of the activities described in use case specifications. The generated conditions are used by UMTG to identify the test inputs that cover all the use case scenarios described in use case specifications. In practice, the proposed approach enables the automated generation of test cases from use case specifications while avoiding most of the additional modeling effort required by UMTG. Results from an industrial case study show that the approach can automatically and correctly generate more than 75% of the pre- and post-conditions characterizing the activities described in use case specifications.
