In diesem Beitrag wird der Umgang mit wissenschaftssprachlichen Wortverbindungen in den beiden Textmustern Paraphrase und Argumentation von Texten luxemburgischer Studienanfänger der Germanistik mit L2 Deutsch genau unter die Lupe genommen. Dafür wird ein Korpus von 37 Lernendentexten nach korpuslinguistischen Kriterien aufbereitet und qualitativ analysiert. Es wird untersucht, welche Wortverbindungen für die beiden Textmuster typisch sind, welche Wortverbindungen bereits beherrscht werden und wo Schwierigkeiten auftreten. Die Untersuchung ergibt, dass die Verwendung von Wortverbindungen textmusterspezifisch ist. Die Fehleranalyse zeigt außerdem, dass von 195 verwendeten Wortverbindungen fast ein Drittel fehlerhaft sind. Dabei treten die größten Schwierigkeiten bei der Trennung zwischen Alltagssprache/Umgangssprache und Wissenschaftssprache auf. Als Maßnahmen für den Unterricht wird das Arbeiten mit Wortverbindungslisten, das selbstständige Ergänzen solcher Listen durch Analysen wissenschaftlicher Mustertexte, die Selbstkontrolle am Eigentext und das Arbeiten mit Korpora empfohlen.

Sentence completion, originally a semi-projective psychological technique, has been used as an effective and lightweight user research method in user experience (UX) design. More information is yet still needed to understand how different sentence stems probe users’ insights, thereby providing recommendations for effective sentence completion surveys. We used the completion method on a large-scale sample to explore (e-)readers’ experiences and needs. Depending on their reading habits, participants (N=1880) were asked to complete a set of sentences, as part of a web survey. With 14143 user ideas collected in two weeks, our results confirm that remote online sentence completion is a cost-effective data collection method able to uncover feelings, attitudes, motivations, needs, or frustrations. Variation in sentence stems affected collected data in terms of item response rate, idea quantity as well as variety and originality. Building on previous research, this paper delivers actionable insights to optimize the richness of sentence completion outputs. [less ▲]

Constructive data physicalization (i.e. the creation of visualizations by non-experts using physical elements) is a promising research area in a context of rapid democratization of data collection and visualization, driven notably by the quantified-self movement. Despite a prolific body of work developed to explore physicalization as a mean to communicate data to individuals, little is known about how people transform data into physical artefacts. Current research also falls short in studying constructive physicalizations using other sensory modalities than sight or touch. Building on the principles of data edibilization, we propose to use candies as a medium to study constructive data physicalization processes, due to their ability to leverage multiple sensory channels. We conducted a preliminary study (candy workshop) to gain insights into how people make use of various sensory modalities in the construction of data physicalizations. We hope to inspire new research using candies as accessible research material. [less ▲]

Office work presents health and wellbeing challenges, triggered by unhealthy working habits or environmental factors. While technologies for vitality in the office context gain popularity, they are often solution-focused and fall short in acknowledging personal needs. Building on approaches from personal informatics, we see value in opening up the design space of tracking and sensing technologies for office workers. We designed and deployed an open-ended sensor kit and conducted two complementary studies to investigate the value of empowering office workers to investigate their own working habits. Findings show that Habilyzer triggers curiosity about working habits, and wireless sensors contribute to inquire into those habits, possibly supported by additional tools. We contribute new insights into how an open-ended sensor kit can be designed to support self-tracking practices and underlying reflections in the underexplored context of office work. It is an alternative approach to workplace vitality, moving from solution-oriented technologies to inquiry-enabling tools. [less ▲]

Office work presents health and wellbeing challenges, triggered by working habits or environmental factors. While technological interventions gain popularity in the workplace, they often fall short of acknowledging personal needs. Building on approaches from personal informatics, we present our vision on the use of user-driven, situated sensor probes in an office context and how the community might deal with complex yet timely questions around the use of data to empower people in becoming explorers of their own habits and experiences. We demonstrate Habilyzer, an open-ended sensor toolkit for office workers, which enables user-driven explorations in self-tracking their work routines. This research contributes an alternative approach to improving working habits and vitality in the workplace, moving from solution-oriented technologies to inquiry-enabling tools. Through this demonstration, we also aim to trigger discussions on the use of sensors and data in the office context, in the light of privacy, consent and data ownership. [less ▲]

Promoting healthy and active lifestyles is an important objective for many governing agencies. The design of active urban environments can be an effective tool to encourage more active behaviors and water features can attract people, improving their experience of the urban space. To explore the potential of these concepts, we designed Fontana; an interactive public installation that aims to stimulate physical activity and social connectedness in the urban outdoor space, using the multidimensional attractiveness of water. We focus on the use of embedded interactive technology to promote physical activity, using water as a linking element between users. Adopting a research-through-design approach, we explored how such installations can nudge people into an active behavior while additionally strengthening social connectedness, using inclusive design principles. We report on insights gathered through this case study and findings of a preliminary user test, discussing the implications of this work for design researchers and practitioners. [less ▲]

Customer Journey Mapping is a widespread service design tool that synthesizes and communicates user research insights to stakeholders. In its common form, a journey map is a synthetic (typically non-interactive) visualization of the key steps of the users’ experience with a service or product. By decomposing the elements of a journey map and staging them under the form of a physical and interactive installation, we intend to leverage the power of journey mapping to break silos and prompt employees within an organization to discover end-users journeys in a compelling and empathic way. This aims to support the user-centered maturity of the organization by developing employees’ curiosity and empathy towards users. We illustrate this approach through a case study on railway passengers’ experiences. We explore the value of richer transfers of user research insights through physical journey maps and discuss design processes and mediums enabling journey maps to come to life. [less ▲]

Empathy towards users is crucial to the design of user-centered technologies and services. Previous research focused on defining empathy and its role in the design process for triggering empathy for end-users. However, there is a lack of empathy measurement instruments in design. Most previous work focused on designers, overlooking the need for other stakeholders to develop empathy towards the users to break organizational silos and deliver high-quality user-centered services and products. In this contribution, we share the preliminary stages of the development of an empathy scale for service design. We build on empathy literature from psychology and design to define 18 items representing four empathy dimensions. We report on the definition of these dimensions and their underlying items, and present preliminary studies in which we reviewed the first version of the scale with experts and stakeholders.

Ambient backscatter communication (AmBC) is an emerging technology that has the potential to offer spectral- and energy-efficient solutions for the next generation wireless communications networks, especially for the Internet of Things (IoT). Intelligent reflecting surfaces (IRSs) are also perceived to be an integral part of the beyond 5G systems to complement the traditional relaying scheme. To this end, this paper proposes a novel system design that enables the co-existence of a backscattering secondary system with the legacy primary system. This co-existence is primarily driven by leveraging the AmBC technique in IRS-assisted unmanned aerial vehicle (UAV) networks. More specifically, an aerial-IRS mounted on a UAV is considered to be employed for cooperatively relaying the transmitted signal from a terrestrial primary source node to a user equipment on the ground. Meanwhile, capitalizing on the AmBC technology, a backscatter capable terrestrial secondary node transmits its information to a terrestrial secondary receiver by modulating and backscattering the ambient relayed radio frequency signals from the UAV-IRS. We comprehensively analyze the performance of the proposed design framework with co-existing systems by deriving the outage probability and ergodic spectral efficiency expressions. Moreover, we also investigate the asymptotic behaviour of outage performance in high transmit power regimes for both primary and secondary systems. Importantly, we analyze the performance of the primary system by considering two different scenarios i.e., optimal phase shifts design and random phase shifting at IRS. Finally, based on the analytical performance assessment, we present numerical results to provide various useful insights and also provide simulation results to corroborate the derived theoretical results.

We assessed parental reflective functioning (PRF) with the Parent Development Interview - Revised, and investigated its association with parenting behaviors, i.e., autonomy support and psychological control (operationalized in terms of behaviors promoting and undermining autonomy relatedness), and stress responses (cortisol reactivity) during a parent-child conflict interaction task (Family Interaction Task). Participants were 40 mothers and 28 fathers, who took part in the study together with their adolescent children (N = 49). Mothers had significantly lower PRF and displayed more psychologically controlling behaviors in the interaction with their children than fathers. Rather than sex per se, high levels of PRF were the best predictors of autonomy support, whereas lower levels of PRF predicted more psychological control. Higher levels of PRF were also the best predictor for lower levels of parenting stress. Stress in the context of parenting was neither related to autonomy support nor to psychological control, which were best predicted by divorced family status. The findings point to the potential utility of interventions aimed at improving PRF and stress management in the context of parenting, especially in divorced families, given their protective effects on parenting behaviors.

Envisioned use cases of unmanned aerial vehicles (UAVs) impose new service requirements in terms of data rate, latency, and sensing accuracy, to name a few. If such requirements are satisfactorily met, it can create novel applications and enable highly reliable and harmonized integration of UAVs in the 6G network ecosystem. Towards this, terahertz (THz) bands are perceived as a prospective technological enabler for various improved functionalities such as ultra-high throughput and enhanced sensing capabilities. This paper focuses on THz-empowered UAVs with the following capabilities: communication, sensing, localization, imaging, and control. We review the potential opportunities and use cases of THz-empowered UAVs, corresponding novel design challenges, and resulting trade-offs. Furthermore, we overview recent advances in UAV deployments regulations, THz standardization, and health aspects related to THz bands. Finally, we take UAV to UAV (U2U) communication as a case-study to provide numerical insights into the impact of various system design parameters and environment factors. [less ▲]
