Differences in culture and mother tongue can have an important impact on the dynamics of an intercultural relationship. In this study the focus lies on the influence of culture and language on expressing love and affection and on other factors like commitment and romantic beliefs in intercultural romantic relationships, and the conflicts that might occur due to the cultural and linguistic differences in intercultural romantic relationships. Two intercultural couples participated in this study. They were interviewed using a semi-structured approach and were recorded. These were transcribed and coded with the coding scheme based on the Grounded Theory. The findings suggest that culture and language have a quite significant influence on expressing love and affection in intercultural romantic relationships. Furthermore, cultural and linguistic differences can have an influence on becoming committed to another person. The expression of romantic beliefs can also be influenced by the different cultural backgrounds. Cultural and linguistic differences can predict conflicts in intercultural romantic relationships. In this study, barriers in communication, differences in religion and different perspectives on concepts such as homosexuality are at the core of these conflicts. [less ▲]

Current humor research tends to accentuate the positive and neglect the negative. Often, the healing power is in the center of humor research; however, less is reported about the negative effects humor can have if not used adequately. In particular, less is known about the appropriate and in-appropriate use of humor in an intercultural context. The purpose of this bachelor thesis was to bridge this lack in humor research by trying to identify the fine line between appropriate and in-appropriate humor. If humor is used appropriately, it can have a huge power to bridge cultural divides. Thus, this thesis aimed as well to investigate the use of humor as a coping strategy in intimate intercultural couples. Thirdly, additional functions of humor shall be explored. Semi-structured, focused interviews were conducted with two intimate intercultural couples. Participants were of Irish, Luxembourgish, German and French-Canadian nationality. Interview data was then analyzed using qualitative content analysis. Results revealed that the appropriate use of humor depends on personal, linguistic, and cultural factors. Overall, self-deprecating humor seems to be the safest type of humor, whereas sarcasm can be experienced as hurtful even if not intended to be. Ethnic humor can have positive effects, too, if it is directed versus the own culture and not versus foreign cultures. Moreover, results revealed that humor mainly serves two functions in intimate intercultural relationships: the one of bonding and the one of coping. Humor as a coping strategy can be used internally, hence related to relationship issues, as well as externally, thus related to external stressors. One can conclude that the function of bonding and coping cannot be clearly distinguished. Consequently, it proves that humor can be a useful tool in bridging intercultural and interpersonal divides. Limitations of the study clearly lie in its sample size, which does not allow to draw any generalizations. In the future, similar studies with a larger sample size as well as with non-Western cultures would be interesting to investigate in the future. [less ▲]

There has not yet been any research done on future planning in international and intercultural couples. The purpose of this case study is to give a first insight into the process of future planning in intercultural couples. A qualitative case study with two participants, one from New Zealand and one from Belgium who are immigrating to New Zealand. One interview with each participant was held before the couple moved to New Zealand for three months and one more interview with each participant after they returned. Results are plentiful. A clear sign that different cultural backgrounds influence future planning seems to exist. Further the couple reported multiple projects and events in which decision making, goal hierarchy and future planning existed. Not all results have been analysed and are available for further use.This case study offers a first insight into future planning of international and intercultural couples. The next step would be to try to support the findings with quantitative data. [less ▲]

Due to the increasing fluctuation between countries and the ongoing emergence of intercultural intimate relationships, the purpose of our study was to investigate how cultural transition affects the identity of women, who migrated out of love to settle permanently with their culturally diverse partner in Germany. Semi-structured interviews were conducted and analyzed by using qualitative content analysis. The sample consists of five women originally from Ireland, Peru, Poland and the United States, who all married a German and have lived in Germany between 8 and 50 years. The results show that cultural transition can affect identity in both positive and negative ways, which supports the perception of bicultural identity being at once both a blessing and a burden.

The purpose of this study is to investigate the influence of culture on child-rearing practices in intercultural marriage. Four participants, respectively two intercultural couples with at least one child in common participated in this study. One couple consisted of a Hungarian woman and Luxembourgish man. The other couple consisted of a Portuguese woman and her husband is Macedonian. Qualitative research methods were used for this study, more specifically semi-structured interviews. These were audio-taped and transcribed afterwards. Grounded theory was used for the analysis of this study. There were no significant results. Cultural influence in child-rearing practices in intercultural marriages could not be fully shown. There is a minimal positive influence but concerning languages In addition, it could not be fully confirmed that parents who come from countries who are considered to be more individualistic value autonomy in their children and parents who come from countries considered to be more collectivistic value more relatedness and conformity. More research is needed in order to obtain significant results. [less ▲]

Against the backdrop of the ongoing crisis-led migration from Southern to Northwestern Europe, the present paper reports on a case study of two families who have recently migrated from Greece to Luxembourg. Luxembourg has a trilingual education system and many pupils of migrant background face difficulties on this account. Drawing on the framework of Family Language Policy, this paper explores the language ideologies and management strategies of two families as well as factors influencing their policies. This qualitative study was based on interviews, observations, and videos recorded by one of the families. The findings show that the families have contrasting language ideologies and management strategies that are informed by their differing transnational experiences, competences and worldviews. This study can contribute to a better understanding of the ways in which migrant families use their language resources in their new country. [less ▲]

Abstract Deep brain stimulation (DBS) is a neurosurgical intervention where electrodes are permanently implanted into the brain in order to modulate pathologic neural activity. The post-operative reconstruction of the DBS electrodes is important for an efficient stimulation parameter tuning. A major limitation of existing approaches for electrode reconstruction from post-operative imaging that prevents the clinical routine use is that they are manual or semi-automatic, and thus both time-consuming and subjective. Moreover, the existing methods rely on a simplified model of a straight line electrode trajectory, rather than the more realistic curved trajectory. The main contribution of this paper is that for the first time we present a highly accurate and fully automated method for electrode reconstruction that considers curved trajectories. The robustness of our proposed method is demonstrated using a multi-center clinical dataset consisting of N=44 electrodes. In all cases the electrode trajectories were successfully identified and reconstructed. In addition, the accuracy is demonstrated quantitatively using a high-accuracy phantom with known ground truth. In the phantom experiment, the method could detect individual electrode contacts with high accuracy and the trajectory reconstruction reached an error level below 100 μm (0.046 ± 0.025 mm). An implementation of the method is made publicly available such that it can directly be used by researchers or clinicians. This constitutes an important step towards future integration of lead reconstruction into standard clinical care. [less ▲]

Multiple extensions of Dung's argumentation frameworks (AFs) have been proposed in order to model features of argumentation that cannot be directly modeled in AFs. One technique that has already previously proven useful to study and combine such extensions is the meta-argumentation methodology involving the notion of a flattening. In order to faithfully model the interaction between explanation argumentation in scientific debates, Šešelja and Straßer have introduced Explanatory Argumentation Frameworks (EAFs). In this paper, we first prove that the flattening technique works as expected for recursive (higher-order) attacks. Then we apply this technique in order to combine EAFs with multiple other extensions that have been proposed to AFs, namely with recursive attacks, joint attacks and a support relation between arguments. This gives rise to Extended Explanatory Argumentation Frameworks (EEAFs). We illustrate the applicability of EEAFs by using them to model a piece of argumentation from a research-level philosophy book. [less ▲]

It is necessary to identify predictors of early reading, foundation of children’s school success. No study in Serbia has investigated this before. The purpose of our study was to identify predictors of early reading and explore correlates of preschool children in Serbia. Children (N=159) age 5-8 were assessed three times over 14 months by an adaptive test, Performance Indicators in Primary School (PIPS). Reading at Time 3 was predicted by gender and mathematics and not by vocabulary and phonological awareness from Time 1. Older children performed higher than younger in vocabulary, phonological awareness, reading and mathematics at Time 1 only. Girls scored higher than boys and Romani scored the lowest in reading at all times. This study offers important information on early reading of an under researched population. Attrition of the sample limits the findings. [less ▲]

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.

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.

Robotic software development frameworks lack a possibility to present,validate and generate qualitative complex human robot interactions and robot de-velopers are mostly left with unclear informal project specifications. The devel-opment of a human-robot interaction is a complex task and involves different ex-perts, for example, the need for human-robot interaction (HRI) specialists, whoknow about the psychological impact of the robot’s movements during the in-teraction in order to design the best possible user experience. In this paper, wepresent a new project that aims to provide exactly this. Focusing on the interac-tion flow and movements of a robot for human-robot interactions we aim to pro-vide a set of modelling languages for human-robot interaction which serves as acommon, more formal, discussion point between the different stakeholders. Thisis a new project and the main topics of this publication are the scenario descrip-tion, the analysis of the different stakeholders, our experience as robot applicationdevelopers for our partner, as well as the future work we plan to achieve.

Human mobility has opened up to many themes in recent years. Human behavior and how a driver might react to certain situations, whether dangerous (e.g. an accident) or simply part of the evolution of new technologies (e.g. autonomous driving), leaves many avenues to be explored. Although experiments have been deployed in real situations, it remains difficult to encounter the conditions that certain studies may require. For this reason, we have set up a driving simulator (comprising several modules) that is able to reproduce a realistic driving environment. Although, as the literature has already demonstrated, the conditions are often far from reality, simulation platforms are nonetheless capable of reproducing an incredibly large number of scenarios on the fly. In this poster, we explain how we conceived the simulator, as well as the system we developed for collecting metrics on both the driver and the simulation environment. In addition, we take advantage of this conference to publicly share a dataset consisting of 25 drivers performing the same road circuit on the "Project Cars" game. [less ▲]
