Abstract
Rehabilitation is an important recovery process from dysfunctions that improves the patient's activities of daily living. On the other hand, collaborative robotic applications, where humans and machines can share the same space, are increasing once it allows splitting a task between the accuracy of a robot and the ability and flexibility of a human. This paper describes an innovative approach that uses a collaborative robot to support the rehabilitation of the upper limb of patients, complemented by an intelligent system that learns and adapts its behaviour according to the patient's performance during the therapy. This intelligent system implements the reinforcement learning algorithm, which makes the system robust and independent of the path of motion. The validation of the proposed approach uses a UR3 collaborative robot training in a real environment. The main control is the resistance force that the robot is able to do against the movement performed by the human arm.

Abstract
Developed focusing agriculture sustainability, mySense is a comprehensive close-range sensor-based data management environment to improve precision farming practices. It integrates discussion platforms for quick problem solving through experts support and a computational intelligence layer for multipurpose application (e.g. vine variety discrimination, plant disease detection and identification). Attending the need for keeping track of agricultural crops not only based on close-range sensing but also at a macro perspective, mySense was complemented with proper functionalities to unlock macro-monitoring features, through the implementation of a Web-based Geographical Information System (WebGIS) planned as a sidekick application that provides agriculture professionals with visual decision support tools over remote sensed data. This paper presents and discusses its specification and implementation.

Abstract
This paper deals with multi-objective location-routing problems (MO-LRPs) and follows a sectorizationapproach, which means customers are divided into different sectors, and a distribution centre is opened for eachsector. The literature has considered objectives such as minimizing the number of opened distribution centres,the variances of compactness, distances and demands in sectors. However, the achievement of these objectivescannot guarantee the geographical separation of sectors. In this sense, and as the geographical separation ofsectors can have significant practical relevance, we propose a new objective function and solve a benchmarkof problems with the non-dominated sorting genetic algorithm (NSGA-II), which finds multiple non-dominatedsolutions. A comparison of the results shows the effectiveness of the introduced objective function, since, in thenon-dominated solutions obtained, the sectors are more geographically separated when the values of the objectivefunction improve.

Abstract
This research analyzes the discrepancies respecting parents' and their children's perspectives on adolescents' risky online behaviors and parental mediation. Rather than focus solely on youth outcomes, this study explores dyadic data, by comparing reports from adolescents attending 7th to 12th grades in Portuguese schools and those of their parents (N=1016). Moreover, this research considers the existence of defense mechanisms influencing adolescents' reports, a factor that has been neglected in previous studies. Differences regarding adolescents' gender, parents' gender, and adolescents' school year are considered and tested using One-way ANOVA. Within the family unit, the only members considered by adolescents to have the same or more online and computer skills than the teenagers themselves are their older siblings. Practical implications aiming to mitigate the risk involved in adolescents' online experiences, and theoretical contributions to the field of prevention and youth well-being in the context of consumer behavior in the digital age are discussed.

Abstract
Nowadays the production systems are linear and the consumption patterns are essentially based on products with a short life cycle, which contribute to increase the demand for raw materials and environmental impacts. The Circular Economy (CE) is playing a major role among scholars and practitioners. Many aspects are now defining this new trending paradigm such as the roles of product development, transformation and remanufacturing/recycling, and/or management of waste, ensuring the economic and environmental benefits. The increasing demand causes instability of the prices and markets, and there is also the risk of supply rupture. This is very unsustainable and puts at risk countries' development. In this work we analyze and assess some EU critical raw material (CRM), considering existing global reserves and production. Correlation between several parameters was also analyzed. Under this assumption one scenario was considered to assess the depletion of two CRM. China is the main supplier in 15 out of 25 CRM considered in this analysis and its average percentage is 65%. Phosphate rock presents the highest value and antimony the lowest for depletion indicator. It was possible to conclude that no significant correlation was found between depletion, self-sufficiency and economic importance indicators. (C) 2019 Published by Elsevier Ltd.

Abstract
Purpose In the context of European consumers' experiences of austerity, this study aims to advance current resilience theory in marketing through developing persistent resilience from a context of austerity influenced consumption. Design/methodology/approach Following an interpretivist approach, 38 face to face, in-depth interviews were conducted with European consumers from Ireland, UK, Spain, Portugal, Italy and Greece who were affected in some way by the global financial crisis. Findings Building upon limited conceptual and empirical investigations in social geography, the analysis identifies the themes of persistent stressors and temporal orientation as constants, alongside day-to-day coping, relating and pragmatism, consumer adjustment, repertoires of resistance and transformation as key elements of persistent resilience within the consumption context of austerity. Research limitations/implications The study addresses the limited theoretical and empirical focus on persistent resilience and austerity and directly contributes to consumer behaviour and marketing theory in understanding persistent resilience and its implications. Practical implications Changes to behaviours as a result of persistent resilience included reducing and stopping consumption, discount shopping, alternative consumption in the form of growing or making and mindful consumption through wastage reduction and re-use. Social implications The study highlights the significant social impact of austerity while also identifying positive outcomes for social relations among family, friends and the wider community. Originality/value This study develops and extends Golubchikov's (2011) theory of persistent resilience through exploring European consumer responses to austerity, identifying key consumption characteristics relevant for marketing theory and practice.
