The need to belong is fundamental to human beings and constitutes a basis for subjective well-being. It is closely linked to further concepts, such as identification, connectedness, attachment, fitting in and feeling “at home”. The present contribution will focus on the sense of belonging in the context of migration in its different facets - cultural, social and spatial - and in relation to different points of reference - national, ethnic and transnational belonging. Applying the lens of cultural psychology of semiotic mediation, the development of a sense of belonging will be discussed with regard to first generation migrants and their second-generation offspring in a life span perspective, drawing on concepts such as proculturation as well as the Trajectory Equifinality Approach.

The increasing levels of software- and data-intensive driving automation call for an evolution of automotive software testing. As a recommended practice of the Verification and Validation (V&V) process of ISO/PAS 21448, a candidate standard for safety of the intended functionality for road vehicles, simulation-based testing has the potential to reduce both risks and costs. There is a growing body of research on devising test automation techniques using simulators for Advanced Driver-Assistance Systems (ADAS). However, how similar are the results if the same test scenarios are executed in different simulators? We conduct a replication study of applying a Search-Based Software Testing (SBST) solution to a real-world ADAS (PeVi, a pedestrian vision detection system) using two different commercial simulators, namely, TASS/Siemens PreScan and ESI Pro-SiVIC. Based on a minimalistic scene, we compare critical test scenarios generated using our SBST solution in these two simulators. We show that SBST can be used to effectively and efficiently generate critical test scenarios in both simulators, and the test results obtained from the two simulators can reveal several weaknesses of the ADAS under test. However, executing the same test scenarios in the two simulators leads to notable differences in the details of the test outputs, in particular, related to (1) safety violations revealed by tests, and (2) dynamics of cars and pedestrians. Based on our findings, we recommend future V&V plans to include multiple simulators to support robust simulation-based testing and to base test objectives on measures that are less dependant on the internals of the simulators.

Emerging and future applications of robotic systems pose unique self-adaptation challenges. To support the research needed to address these challenges, we provide an extensible repository of robotic mission adaptation exemplars. Co-designed with robotic application stakeholders including researchers, developers, operators, and end-users, our repository captures key sources of uncertainty, adaptation concerns, and other distinguishing characteristics of such applications. An online form enables external parties to supply new exemplars for curation and inclusion into the repository. We envisage that our RoboMAX repository will enable the development, evaluation, and comparison of much-needed self-adaptation approaches for the robotic systems domain. [less ▲]

Efforts to combat the COVID-19 crisis were characterized by a difficult trade-off: the stringency of the lockdowns decreased the spread of the virus, but amplified the damage to the economy. In this study, we analyze public attitudes toward this trade-off on the basis of a survey and survey-embedded experiment of more than seven thousand respondents from Southeast Europe, collected in April and May 2020. The results show that public opinion generally favored saving lives even at a steep economic cost. However, the willingness to trade lives for the economy was greater when the heterogeneous health and economic consequences of lockdown policies for the young and the elderly were emphasized. Free market views also make people more acceptant of higher casualties, as do fears that the instituted measures will lead to a permanent expansion of government control over society. [less ▲]

Being capable of estimating the pose of uncooperative objects in space has been proposed as a key asset for enabling safe close-proximity operations such as space rendezvous, in-orbit servicing and active debris removal. Usual approaches for pose estimation involve classical computer vision-based solutions or the application of Deep Learning (DL) techniques. This work explores a novel DL-based methodology, using Convolutional Neural Networks (CNNs), for estimating the pose of uncooperative spacecrafts. Contrary to other approaches, the proposed CNN directly regresses poses without needing any prior 3D information. Moreover, bounding boxes of the spacecraft in the image are predicted in a simple, yet efficient manner. The performed experiments show how this work competes with the state-of-the-art in uncooperative spacecraft pose estimation, including works which require 3D information as well as works which predict bounding boxes through sophisticated CNNs.

The analysis of the concept of inclusion in a scientific context and the inflationary classification of different practices as inclusive suggest a rethinking of inclusion as a guiding concept in social work. Inclusion in the sociological sense means something other than the pedagogical postulate of education for all. Inclusion is sometimes understood as a method (inclusive education), sometimes as an ethical principle (human right) and sometimes as a global goal (the inclusive society). In the neoliberal model, inclusion represents a practice of obligation to contribute to economic growth and to comply with market requirements. Due to its proximity to the everyday life of the people, social work has a growing role to play in pointing out the tension between an inclusion promise in the front stage and a back stage on which social exclusion is legitimised.

Dans le rapport entre le principe de primauté et la protection des droits fondamentaux la question de la répartition des compétences ne semble pas, à première vue, se poser : la primauté nous place dans la sphère de compétence de l’Union, alors que la protection des droits fondamentaux, comme contestation de la primauté, relève de la sphère nationale. Le conflit entre primauté et droits fondamentaux relève ainsi du rapport des ordres juridiques et est résolu par leur interaction, exprimée dans la balance entre le principe de coopération loyale et la prise en compte des intérêts nationaux, sur la base du respect de l’identité nationale ou en invoquant l’article 53 de la Charte . En ce sens, la problématique des compétences n’entre pas en ligne de compte. Cependant, l’élaboration de standards européens de protection des droits fondamentaux, en tant qu’objet direct ou indirect de l’exercice des compétences de l’Union, peut servir le compromis issu du principe d’attribution. Ainsi, primauté et droits fondamentaux peuvent être abordés sous l’angle des compétences. Le rapport entre primauté et droits fondamentaux n’est toutefois pas forcément conflictuel. La Charte est source d’obligations pour les Etats membres au-delà du champ couvert par l’exercice des compétences de l’Union. Il est bien établi que la notion de mise en œuvre du droit de l’Union en tant que condition de l’application de la Charte à l’égard des Etats membres, est entendue dans le sens du domaine couvert par le droit de l’Union. Ainsi, les standards européens de protection sont eux-mêmes couverts par la primauté et interviennent dans l’encadrement de l’autonomie nationale et l’articulation des compétences [less ▲]

Deep neural networks (DNNs) are increasingly im- portant in safety-critical systems, for example in their perception layer to analyze images. Unfortunately, there is a lack of methods to ensure the functional safety of DNN-based components. We observe three major challenges with existing practices regarding DNNs in safety-critical systems: (1) scenarios that are underrepresented in the test set may lead to serious safety violation risks, but may, however, remain unnoticed; (2) char- acterizing such high-risk scenarios is critical for safety analysis; (3) retraining DNNs to address these risks is poorly supported when causes of violations are difficult to determine. To address these problems in the context of DNNs analyzing images, we propose HUDD, an approach that automatically supports the identification of root causes for DNN errors. HUDD identifies root causes by applying a clustering algorithm to heatmaps capturing the relevance of every DNN neuron on the DNN outcome. Also, HUDD retrains DNNs with images that are automatically selected based on their relatedness to the identified image clusters. We evaluated HUDD with DNNs from the automotive domain. HUDD was able to identify all the distinct root causes of DNN errors, thus supporting safety analysis. Also, our retraining approach has shown to be more effective at improving DNN accuracy than existing approaches. [less ▲]
