In this paper, we propose to detect an action as soon as possible and ideally before it is fully completed. The objective is to support the monitoring of surveillance videos for preventing criminal or terrorist attacks. For such a scenario, it is of importance to have not only high detection and recognition rates but also low time latency for the detection. Our solution consists in an adaptive sliding window approach in an online manner, which efficiently rejects irrelevant data. Furthermore, we exploit both spatial and temporal information by constructing feature vectors based on temporal blocks. For an added efficiency, only partial template actions are considered for the detection. The relationship between the template size and latency is experimentally evaluated. We show promising preliminary experimental results using Motion Capture data with a skeleton representation of the human body. [less ▲]

The Controlled Foreign Company (CFC) regime proposed by the Commission as part of the newly launched Common Corporate Tax Base (CCTB) project reflects the perceived need to strengthen the Union’s anti-tax avoidance measures, and specifically to discourage profit shifting to low-tax jurisdictions. The proposed rule largely reflects previous work done by the OECD as part of the BEPS project and the EU implementation measures in the Anti-Tax Avoidance Directive (ATAD), but it deviates from both in a number of its details. This contribution aims to provide a first technical analysis of the provision to reveal its scope, its mechanism, and apparent shortcomings. It furthermore tries to imbed it in its context of existing primary and secondary EU law. [less ▲]

Dry-stacked masonry walls gives rise to geometric imperfections: the height variation of different masonry blocks ΔH and the roughness of the support area Δh. This paper studies the effect of ΔH on the structural response and the load bearing capacity of masonry walls by highlighting the load percolation. Furthermore, an algorithm was developed to define a stress multiplier coefficient respecting the imperfections ΔH. The algorithm allowed predicting 77% of the amplified stress compared to the FE analysis and showed that the geometric imperfections govern the load percolation in a wall as well as the cracking mode and the bearing capacity.

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 ▲]

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.

In 2013 Juels and Rivest introduced the Honeywords System, a password-based authentication system designed to detect when a password file has been stolen. A Honeywords System stores passwords together with indistinguishable decoy words so when an intruder steals the file, retrieves the words, and tries to log-in, he does not know which one is the password. By guessing one from the decoy words, he may not be lucky and reveal the leak. Juels and Rivest left a problem open: how to make the system secure even when the intruder corrupted the login server’s code. In this paper we study and solve the problem. However, since “code corruption” is a powerful attack, we first define rigorously the threat and set a few assumptions under which the problem is still solvable, before showing meaningful attacks against the original Honeywords System. Then we elicit a fundamental security requirement, implementing which, we are able to restore the honeywords System’s security despite a corrupted login service. We verify the new protocol’s security formally, using ProVerif for this task. We also implement the protocol and test its performance. Finally, at the light of our findings, we discuss whether it is still worth using a fixed honeywords-based system against such a powerful threat, or whether it is better, in order to be resilient against code corruption attacks, to design afresh a completely different password-based authentication solution.

Aggressive drivers can make driving dangerous. Over 50% of traffic fatalities are caused by aggressive driving. Aggressive motorists make driving very dangerous. This research tests whether narcissists are more aggressive drivers than other individuals. Narcissists think they are special people who deserve special treatment. When they don’t get the special treatment they think they deserve, narcissists often lash out at others in an aggressive manner. Narcissists might think they “own the road” and can drive anyway they want, and that other drivers should get out of their way. In the article, we conduct three studies to test the link between narcissism and aggressive driving. In Studies 1 (N=139) and 2 (N=100), Luxembourgish motorists completed a measure of narcissism and a self-report measure of aggressive driving. In Study 3 (N=60), American university students completed a measure of narcissism and then completed a driving simulation scenario that contained a number of frustrating elements. Several measures of aggressive driving and road rage were obtained. In all three studies, narcissism was positively related to aggressive driving. A meta-analysis found an average correlation of r=.35 across the three studies. This research replicates previous research linking narcissism to aggression, and extends it to a driving context.
