This paper studies convergence of credit structure worldwide. We hand-collect data on credit to household and firm credit for 143 countries over the period 1995-2014. First, we separately document the existence of a convergence process of total credit, household credit and firm credit, respectively. Second, we find that convergence of household credit occurs faster than firm credit, inducing a process of convergence of the share of household credit to total credit. Third, convergence occurs faster in low-income countries and in countries with a lower initial level of total credit but slows down after the 2008 global financial crisis. Finally, our data investigation does not support the idea that convergence is driven by changing conditions in developing countries. [less ▲]

Attack trees provide a systematic way of characterizing diverse system threats. Their strengths arise from the combination of an intuitive representation of possible attacks and availability of formal mathematical frameworks for analyzing them in a qualitative or a quantitative manner. Indeed, the mathematical frameworks have become a large focus of attack tree research. However, practical applications of attack trees in industry largely remain a tedious and error-prone exercise. Recent research directions in attack trees, such as attack tree generation, attempt to close this gap and to improve the attack tree state-of-thepractice. In this position paper we outline the recurrent challenges in manual tree design within industry, and we overview the recent research results in attack trees that help the practitioners. For the challenges that have not yet been addressed by the community, we propose new promising research directions. [less ▲]

The discrete Pompeiu problem is stemmed from an integral-geometric question on the plane. The problem is whether we can reconstruct a function if we know the average values of the function on every congruent copy of a given pattern. After introducing the theory of spectral analysis on discrete Abelian groups, I show some results for the discrete version of the problem. One of the arguments is connected to a coloring problem of the plane. One of them is a geometric construction and some others based on some geometric and combinatoric properties of the plane. I also mention some unsolved questions of the topic. My talk is based on a joint work with M. Laczkovich and Cs. Vincze. [less ▲]

Robert Triffin (1911-1993), a Belgian-born economist who spent much of his career in America, had a major influence on 20th-century economic thinking. He is particularly known for his monetary approach. His intellectual legacy revolves ariund the 'Triffin dilemma' or 'Triffin paradox'. Triffin accurately predicted the end of the Bretton Woods system, though not for the right reasons. Triffin stuck by his monetary theory that it was much harder to achieve sound international economic management with flexible exchange rates and that best practices were by no means a guarantee of global stability if they were not accompanied by genuine international coordination. Triffin was also a committed European. He was close to Jean Monnet and Pierre Werner and worked alongside them from the early 1960's onwards in favour of European monetary integration. [less ▲]

The investigation and condition assessment of bridges have a very high priority in the construction industry today. Particularly, due to the fact that many bridge structures are getting old and partly reach the end of their useful life, the control and condition assessment of bridge structures have become very important and essential. The present research work introduces an efficient new method for condition assessment called the Deformation Area Difference (DAD) Method. This new method represents an attractive alternative to visual inspection and long-term monitoring. In this paper, the new method with its theoretical background is presented and explained by means of a laboratory experiment and some additional theoretical calculation examples. The experimental investigations have been realised on a reinforced concrete beam, which has been gradually loaded until failure. For each load step, the stiffness reduction and the apparent cracking have been monitored. High-precision measurements such as close-range photogrammetry, digital levelling and displacement sensors have been used for the determination of the deflection curve. The DAD method has been applied to identify the area of the crack pattern of the laboratory experiment. Furthermore, the method is discussed with regard to the load level and the precision of the deformation measurements. On the basis of the laboratory experiment, the applicability of the DAD method for damage detection could be proven. Furthermore, the sensitivity of the method with regard to the damage degree, the static system, the damage position and the impact of temperature variation were analysed. [less ▲]

Young children’s socio-emotional skills are important for understanding their own and other’s behaviours and interactions. No study in Serbia has investigated this before. In this study we explored the links between early socio-emotional skills, behaviour and cognitive development of preschool children in Serbia over time. Children (N=159) aged 5-8 were rated by the teachers on their socio-emotional skills and behaviour, and their literacy and mathematics assessed, at three-time points over 14 months. At Time 3, children’s socio-emotional skills and behaviour were associated with gender and mathematics. Mathematics was associated with children’s social skills and literacy. Literacy was associated with adjustment, gender and mathematics. At all three times, girls were rated more positively than boys. This study offers the first insight into the relationship between socio-emotional skills, behaviour and mathematics and literacy performance of preschool children in Serbia which will inform the development and evaluation of interventions. Attrition of the sample limits the findings. [less ▲]

The interest in studying addictive use of online sexual activities (OSA) has grown sharply over the last decade. Despite the burgeoning number of studies conceptualizing the excessive use of OSA as an addictive disorder, few have tested its relations to impulsivity, which is known to constitute a hallmark of addictive behaviors. To address this missing gap in the literature, we tested the relationships between addictive OSA use, impulsivity traits, and affect among a convenience sample of men (N = 182; age, M = 29.17), building upon a theoretically driven model that distinguishes the various facets of impulsivity. Results showed that negative urgency (an impulsivity trait reflecting the tendency to act rashly in negative emotional states) and negative affect interact in predicting addictive OSA use. These results highlight the pivotal role played by negative urgency and negative affect in addictive OSA use, supporting the relevance of psychological interventions that focus on improving emotional regulation (e.g., to reduce negative affect and learn healthier coping strategies) to mitigate excessive use of OSA.
