The Internet of Things (IoT) relies on sensor devices to measure real-world phenomena in order to provide IoT services. The sensor readings are shared with multiple entities, such as IoT services, other IoT devices or other third parties. The collected data may be sensitive and include personal information. To protect the privacy of the users, the data needs to be protected through an encryption algorithm. For sharing cryptographic cipher-texts with a group of users Attribute-Based Encryption (ABE) is well suited, as it does not require to create group keys. However, the creation of ABE cipher-texts is slow when executed on resource constraint devices, such as IoT sensors. In this paper, we present a modification of an ABE scheme, which not only allows to encrypt data efficiently using ABE, but also reduces the size of the cipher-text, that must be transmitted by the sensor. We also show how our modification can be used to realise an instantaneous key revocation mechanism.

Aims: Intercultural competence has become a key-competence, since the world has become more and more volatile, uncertain, complex and ambiguous. Therefore, insights in the development of intercultural competence and its´ links to individual traits are crucial for companies and researchers to face the requirements in a VUCA world. This study examines the relationship between the time, students spent abroad, personality traits and circumstances during this time with the student’s intercultural competence and integration performance in the target culture. The study had a correlative cross-sectional design. Design and sample: A total of 202 academic subjects were surveyed. The average age was 22 years. There was one measuring time, to which 58 % of the participants stated that they have had a stay abroad. Measurements: Metacognitive, cognitive, motivational and behavioural intercultural competence were measured with the Cultural Intelligence Scale. The personality traits involvement, discipline, social competence, cooperation, dominance and stability were captured with the "Bochum inventory for job-related personality description-6F". Work-related attitudes as patterns of behaviour and experience were measured using the "Work-related Behaviour and Experiencing Pattern 44" (German: Arbeitsbezogene Verhaltens- und Erlebensmuster, AVEM). This scale captures the way participants relate to work in general based on the measurement of personality traits and their fit to specific clusters, which describe, whether individuals have healthy or risky patterns. In addition, the demographic factors and characteristics of stays abroad as well as the integration into the target culture based on the Sociocultural Adaption Scale were examined. The data was tested for relationships and differences by tests for mean differences, variance and regression analyses. Results: There was a positive correlation between duration and cognitive, motivational and behavioural intercultural competence. The motivational competence is higher in subjects who have no risk pattern in the AVEM. The different types of competence influence each other at diverse times. Moreover, the suggested structural equation model could be confirmed. This showed the effect of the AVEM pattern on intercultural competence, moderated by the stay abroad and the social competence. Thus, the study contributes to the understanding of both the measurement of intercultural competence and the development process of intercultural competence in a globalized world.

The increasing complexity of caseloads in SLT practice, e.g. due to higher comorbidity, lacking information or experience in the treatment of complicated cases, calls for support from experienced as well as specialist practitioners from within the field - especially for novice therapists. One way to tackle these challenges may be peer coaching and how it can be employed within the educational and professional SLT setting. Peer coaching was implemented across five semesters of a successive SLT study programme at a University of Applied Sciences in Germany. The approach was embedded in a clinical reasoning seminar with 25 SLT students who each presented a challenging case study from their current workload. All participants completed a short online survey to evaluate the feasibility of the team approach within this setting as well as their personal benefit and development re. the discussed case studies. Students felt encouraged by being able to share their experience and tackle actual challenges. They particularly valued receiving answers from a broad range of other SLTs but also contributing to other students’ queries and providing practical solutions for them. All participants felt that peer coaching was an appropriate approach for clinical reasoning to support their professional as well as personal development. Other outcomes were a perceived increased ability to employ metacognitive reflection to be used with their whole caseload but also a prospective need for further training. Some students suggested the employment of peer coaching within their work setting. In the educational as well as professional SLT setting, peer coaching can be successfully employed, triggering metacognitive reflection re. practitioner’s thinking and acting, resulting in an increased awareness of needs and skills as part of the clinical reasoning process.

Teachers in health informatics have a broad variety of international and national educational recommendations to rely on when designing programmes, curricula, courses and educational material. However, in addition they often need very specific information for their setting, blue-prints, hands-on experience and encouragement to try something new. This workshop presents three case studies from European universities who have implemented inter-professional, technology enabled health informatics courses in undergraduate, postgraduate and open university settings. These approaches will be put into the context of the TIGER recommendation framework that includes priority ratings of health informatics competencies and case studies to illustrate them. The workshop attendees will have ample opportunity to exchange ideas with the presenters and start a mutual learning process for health informatics teachers.

The demographic shift in the age structure has the effects that many ageing employees work in organisations. Migration can slow down the ageing of population but could not stop it. More and more people with immigration background work in organisations. Therefore, the question is, whether diversity sensitive attitudes count for all diversity aspects. The central aim of the study is to deal with the problem fields of multicultural teamwork. Thereby, the focus is on the collaboration of employees with and without immigration background. The interviews with employees with and without an immigra-tion background of various company branches were conducted. The results show that employees with an immigration background have more contact and feel comfortable with persons from different cultures than employees without an immigration back-ground. The qualitative analysis indicates that there is a high need of competence devel-opment, especially intercultural and social competences in organisations. The results of the study reveal that personality traits and characteristics of employees play a role to what extent they accept diversity and are willing to work with persons from another culture. Age is not important regarding intercultural competence development.
