Risk-taking, when unregulated by good executive function, may predispose youth to potentially dangerous behaviors such as substance abuse, unsafe sex practices, and criminal activity. The computer-based Balloon Analogue Risk Task (BART) has been widely used to study risk-taking propensity and predict real-world risky behaviors. We administered the youth version BART-Y to 6,929 children between grades K-8 and hypothesize that executive function, a cognitive skillset for self-regulation controlled by the frontal lobe, improves risk tolerance. Our preliminary results show that BART Total Points increased across grades and also significantly improved (p < 0.001) over repeated trials, supporting our proposition that risk tolerance is strengthened in parallel with cognitive development.

Harvesting tasks gather information to a central repository. We studied 880560 harvesting tasks from 3446 harvesting services in 354 harvesting rounds during a period of 15 months, of which 382705 failed and the remaining tasks occasionally returning fewer records. A significant part of the Open Archive Initiative harvesting services never worked or have ceased working while many other services fail occasionally. A harvesting task includes many stages of information exchange, and each one of them may fail - but with different consequences each time. We studied the reported warning messages, the number of records returned, and the required response time to discover relations among them. We found that about half of the harvesting tasks on each harvesting round fail, and the number of failing tasks is slowly increasing. We developed a method of analysis that can be used to reverse engineering such complex network systems and to categorize the reasons of failure into useful classes. Our results do not indicate a new approach to harvesting or conclude to a breakthrough advice, but make clear the complexity of the operation in an ever changing networking environment and alarm the reader that some facts that may be considered trivial, actually they are not! They help us to better understand the risks involved, and to design more reliable procedures and improved ways to closely monitor them.

Technology assisted home based rehabilitation therapy offers a potentially cost-effective and convenient solution for those affected by neuro and musculoskeletal impairments. Home based solutions, however, face many challenges, the most significant of which is trying to reproduce a complex adaptive therapy experience in the home without the continuous presence of the therapist. Building on our prior work creating interactive systems for the clinic, we present our home-based system that integrates customized therapy objects, camera based movement capture and assessment techniques, and a flexible exercise protocol aimed at generalizing to variable daily life activities. We present findings from two pilot studies with unimpaired and impaired users and describe how insights from these studies will guide future work.

Unfortunately, today people drive more and walk less. The use of vehicles has become the main way of traveling, even for short distances. This has a negative impact on many socioeconomic areas, some of which are related to the planning of cities, the health of people, the natural environment, and generally the quality of life. This paper presents a market research study investigating citizens' attitudes on the pedestrian network conditions as well as the potential for a smartphone application that provides users relevant information for effective route selection and connectivity to enhance and improve their walking experience. For this purpose, an on-site survey was carried out in two selected areas, one with low quality pedestrian network conditions and the other with high quality pedestrian network conditions. Based on the analysis of the collected data, we see that citizens are aware that walking is beneficial for their health and have a positive attitude towards walking. However, it seems that the adverse walking conditions negatively influence the actual decision to walk. Further, there seems to be a demand for a smartphone pedestrian network application that provides relevant information to citizens, but this is dependent on specific business models. This paper contributes to sustainable development and the idea of a smart city. The findings support further research to be carried out to develop and market such a system, which would be useful both for citizens and local governments in order to improve urban spaces, the natural environment and the quality of life.

In this paper, a novel approach for the analysis of the movement evolution in patients with Parkinson's disease is presented. The system offers the capabilities of detecting significant degradations in the motor-skills of the patients according to the physiotherapy evaluations, where seven items are measured, including: posture, balance, walking, postural changes, involuntary movements, movement coordination and rigidity. To assess their evolution, two modules are employed: a data analysis module, which uses a clustering algorithm to distribute patients according to their skills and analyses their evolution based on the last three evaluations, and a Decision Support Tool based on a Fuzzy-Logic system, which measures the state of the patient according to the results from the mentioned data analysis module and generates a report per patient including his/her state at each item as well as recommendations considering convenient exercises to be practiced. Thus, the system provides meaningful information to physiotherapists, to support them in the decision-making process.

This paper presents COIN-O-RAMA, an interactive exhibit designed for exploring and further engaging with coins in physical exhibitions. The key motivation was to create an appealing and user friendly system, augmenting and complementing the overall experience of visiting the exhibition, also offering the means for creating a personalized digital souvenir (a coin with the user's head engraved on it), working as a post-visit link to the exhibition and to related information, as well as an artifact to share with friends and the social media. In this paper the requirements and preferences upon which the creation of COIN-O-RAMA was based are presented, followed by an account of the conceptual and interaction / user interface design of the system. Subsequently, a technical description of the process followed to achieve the engraving effect used for creating the personalized digital coin is offered. Then, the results of an expert evaluation of a fully working prototype of the system are reported, comprising issues raised by the evaluators and the corresponding re-design of the system. The paper wraps up with some conclusions and pointers to future work.

We are experiencing a trend of personal fabrication that allows non-experts to produce highly individualized objects. Beyond 3D printing, this maker movement also approaches larger-scale production machines such as computer numerically controlled (CNC) milling machines that are available in local fabrication laboratories (FabLabs). While the user interfaces and interaction techniques of small-scale 3D printers for household use adapted to the new requirements of non-experts in the last years, such an overhaul of the interfaces for larger machinery is still missing. In this work, we explore the use of augmented reality methods to support novice users in the operation of CNC milling machines. As a first step towards better support for users, we provide a camera-supported graphical and easy-to-use interface for the measurement of raw workpieces inside the machine. In this paper, we contribute our concept CaMea alongside its' prototype implementation. We further report on the findings of a first early user study.

A key issue in studying the performance of wireless sensor networks is the study of load and, depending on the case, different definitions can be found in the literature. These definitions may vary significantly and they may not allow for further investigation of particular aspects of the network's behavior, thus impending the researcher's work. The purpose of this paper is to lift any ambiguities with respect to widely used load definitions, analyze their properties and provide for a new perspective to study wireless sensor networks' performance, particularly for the case of uniform random node deployment. First, definitions regarding the node load, the average area load and the average point load, the most widely used cases considered in the literature, are presented. Subsequently, the relation among these definitions is analytically investigated, resulting in an analytical expression between the average area load and the average load of the points within this area. As it is concluded, average load can be seen as a property of every single point, even if that point is not occupied by a sensor, which introduces a different way to tackle average load problems in wireless sensor network environments.

In this paper, we present a taxonomy in Robot-Assisted Training; a growing body of research in Human-Robot Interaction which focuses on how robotic agents and devices can be used to enhance user's performance during a cognitive or physical training task. The proposed taxonomy includes a set of parameters that characterize such systems, in order to highlight the current research trends and needs for the design, development and evaluation of Robot-Assisted Training systems. Towards this direction, we review related taxonomies in Human Robot Interaction, as well as recent works and applications in Robot-Assisted Training. The motivation of this research is to identify and discuss issues and challenges, focusing on the personalization aspects of a Robot-Assisted Training system.
