Special relativity theory (SRT) has recently gained popularity as a first introduction to “modern” physics thinking in upper level secondary physics education. A central idea in SRT is the absolute speed of light, with light propagating with uniform speed relative to the reference frame of the observer. Previous research suggests that students, building on their prior understandings of light propagation and relative motion, develop misunderstandings of this idea. The available research provides little detail on the reasoning processes underlying these misunderstandings. We therefore studied secondary education students’ preinstructional reasoning about the speed of light in a qualitative study, probing students’ reasoning through both verbal reasoning and drawing. Event diagrams (EDs) were used as a representational tool to support student reasoning. Results show that students productively use EDs to reason with light propagation. In line with previous research, we found two alternative reference frames students could use for uniform light propagation. Most students show a flexibility in their use of reference frame: They not only evaluate light propagation in their preferred frame of reference, but also relative to other frames. Some students experienced conflict between an alternative reference frame and the speed of light and changed their reasoning because of that. This finding suggests promising directions for designing education.

Background: Profiling the plant root architecture is vital for selecting resilient crops that can efficiently take up water and nutrients. The high-performance imaging tools available to study root-growth dynamics with the optimal resolution are costly and stationary. In addition, performing nondestructive high-throughput phenotyping to extract the structural and morphological features of roots remains challenging. Results: We developed the MultipleXLab: a modular, mobile, and cost-effective setup to tackle these limitations. The system can continuously monitor thousands of seeds from germination to root development based on a conventional camera attached to a motorized multiaxis-rotational stage and custom-built 3D-printed plate holder with integrated light-emitting diode lighting. We also developed an image segmentation model based on deep learning that allows the users to analyze the data automatically. We tested the MultipleXLab to monitor seed germination and root growth of Arabidopsis developmental, cell cycle, and auxin transport mutants non-invasively at high-throughput and showed that the system provides robust data and allows precise evaluation of germination index and hourly growth rate between mutants. Conclusion: MultipleXLab provides a flexible and user-friendly root phenotyping platform that is an attractive mobile alternative to high-end imaging platforms and stationary growth chambers. It can be used in numerous applications by plant biologists, the seed industry, crop scientists, and breeding companies.

Background: Despite the increasing attention for the positive effects of physical activity (PA), nearly half of the Dutch citizens do not meet the national PA guidelines. A promising method for increasing PA are mobile exercise applications (apps), especially if they are embedded with theoretically supported persuasive strategies (e.g., goal setting and feedback) that align with the needs and wishes of the user. In addition, it is argued that the operationalization of the persuasive strategies could increase the effectiveness of the app, such as the actual content or visualization of feedback. Although much research has been done to examine the preferences for persuasive strategies, little is known about the needs, wishes, and preferences for the design and operationalization of persuasive strategies.Objective: The purpose of this study was to get insight in the needs, wishes, and preferences regarding the practical operationalization of persuasive strategies in a mobile application aimed at promoting PA in healthy inactive adults.Methods: Five semistructured focus groups were performed. During the focus groups, the participants were led into a discussion about the design and operationalization of six predefined theory-based persuasive strategies (e.g., self-monitoring, feedback, goal setting, reminders, rewards, and social support) directed by two moderators. The audio-recorded focus groups were transcribed verbatim and analyzed following the framework approach.Results: Eight men and 17 women between 35 and 55 years (mean age, 49.2) participated in the study. Outcomes demonstrated diverse preferences for implementation types and design characteristics of persuasive strategies in mobile applications. Basic statistics (such as distance, time and calories), positive feedback based on easy-to-achieve goals that relate to health guidelines, and motivating reminders on a relevant moment were preferred. Participants had mixed preferences regarding rewards and a social platform to invite other users to join PA.Conclusions: Findings indicated that in mHealth applications for healthy but inactive adults, persuasive strategies should be designed and implemented in a way that they relate to health guidelines. Moreover, there is a need for an app that can be adapted or can learn based on personal preferences as, for example, preferences with regard to timing of feedback and reminders differed between people.
The project aims to improve palliative care in China through the competence development of Chinese teachers, professionals, and students focusing on the horizontal priority of digital transformation.Palliative care (PC) has been recognised as a public health priority, and during recent years, has seen advances in several aspects. However, severe inequities in the access and availability of PC worldwide remain. Annually, approximately 56.8 million people need palliative care, where 25.7% of the care focuses on the last year of person’s life (Connor, 2020).China has set aims for reaching the health care standards of the developed countries by 2030 through the Healthy China Strategy 2030, where one of the improvement areas in health care includes palliative care, thus continuing the previous efforts.The project provides a constructive, holistic, and innovative set of actions aimed at resulting in lasting outcomes and continued development of palliative care education and services. Raising the awareness of all stakeholders on palliative care, including the public, is highly relevant and needed. Evidence based practice guidelines and education are urgently required for both general and specialised palliative care levels, to increase the competencies for health educators, professionals, and students. This is to improve the availability and quality of person-centered palliative care in China. Considering the aging population, increase in various chronic illnesses, the challenging care environment, and the moderate health care resources, competence development and the utilisation of digitalisation in palliative care are paramount in supporting the transition of experts into the palliative care practice environment.General objective of the project is to enhance the competences in palliative care in China through education and training to improve the quality of life for citizens. Project develops the competences of current and future health care professionals in China to transform the palliative care theory and practice to impact the target groups and the society in the long-term. As recognised by the European Association for Palliative Care (EAPC), palliative care competences need to be developed in collaboration. This includes shared willingness to learn from each other to improve the sought outcomes in palliative care (EAPC 2019). Since all individuals have a right to health care, project develops person-centered and culturally sensitive practices taking into consideration ethics and social norms. As concepts around palliative care can focus on physical, psychological, social, or spiritual related illnesses (WHO 2020), project develops innovative pedagogy focusing on evidence-based practice, communication, and competence development utilising digital methods and tools. Concepts of reflection, values and views are in the forefront to improve palliative care for the future. Important aspects in project development include health promotion, digital competences and digital health literacy skills of professionals, patients, and their caregivers. Project objective is tied to the principles of the European Commission’s (EU) Digital Decade that stresses the importance of placing people and their rights in the forefront of the digital transformation, while enhancing solidarity, inclusion, freedom of choice and participation. In addition, concepts of safety, security, empowerment, and the promotion of sustainable actions are valued. (European Commission: Digital targets for 2030).Through the existing collaboration, strategic focus areas of the partners, and the principles of the call, the PalcNet project consortium was formed by the following partners: JAMK University of Applied Sciences (JAMK ), Ramon Llull University (URL), Hanze University of Applied Sciences (HUAS), Beijing Union Medical College Hospital (PUMCH), Guangzhou Health Science College (GHSC), Beihua University (BHU), and Harbin Medical University (HMU). As project develops new knowledge, innovations and practice through capacity building, finalisation of the consortium considered partners development strategy regarding health care, (especially palliative care), ability to create long-term impact, including the focus on enhancing higher education according to the horizontal priority. In addition, partners’ expertise and geographical location was also considered important to facilitate long-term impact of the results.Primary target groups of the project include partner country’s (China) staff members, teachers, researchers, health care professionals and bachelor level students engaging in project implementation. Secondary target groups include those groups who will use the outputs and results and continue in further development in palliative care upon the lifetime of the project.
This project addresses the fundamental societal problem that encryption as a technique is available since decades, but has never been widely adopted, mostly because it is too difficult or cumbersome to use for the public at large. PGP illustrates this point well: it is difficult to set-up and use, mainly because of challenges in cryptographic key management. At the same time, the need for encryption has only been growing over the years, and has become an urgent problem with stringent requirements – for instance for electronic communication between doctors and patients – in the General Data Protection Regulation (GDPR) and with systematic mass surveillance activities of internationally operating intelligence agencies. The interdisciplinary project "Encryption for all" addresses this fundamental problem via a combination of cryptographic design and user experience design. On the cryptographic side it develops identity-based and attribute-based encryption on top of the attribute-based infrastructure provided by the existing IRMA-identity platform. Identity-based encryption (IBE) is a scientifically well-established technique, which addresses the key management problem in an elegant manner, but IBE has found limited application so far. In this project it will be developed to a practically usable level, exploiting the existing IRMA platform for identification and retrieval of private keys. Attribute-based encryption (ABE) has not reached the same level of maturity yet as IBE, and will be a topic of further research in this project, since it opens up attractive new applications: like a teacher encrypting for her students only, or a company encrypting for all employees with a certain role in the company. On the user experience design side, efforts will be focused on making these encryption techniques really usable (i.e., easy to use, effective, efficient, error resistant) for everyone (e.g., also for people with disabilities or limited digital skills). To do so, an iterative, human-centred and inclusive design approach will be adopted. On a fundamental level, scientific questions will be addressed, such as how to promote the use of security and privacy-enhancing technologies through design, and whether and how usability and accessibility affect the acceptance and use of encryption tools. Here, theories of nudging and boosting and the unified theory of technology acceptance and use (known as UTAUT) will serve as a theoretical basis. On a more applied level, standards like ISO 9241-11 on usability and ISO 9241-220 on the human-centred design process will serve as a guideline. Amongst others, interface designs will be developed and focus groups, participatory design sessions, expert reviews and usability evaluations with potential users of various ages and backgrounds will be conducted, in a user experience and observation laboratory available at HAN University of Applied Sciences. In addition to meeting usability goals, ensuring that the developed encryption techniques also meet national and international accessibility standards will be a particular point of focus. With respect to usability and accessibility, the project will build on the (limited) usability design experiences with the mobile IRMA application.
In leaving the more traditional territories of the concert performance for broader societal contexts, professional musicians increasingly devise music in closer collaboration with their audience rather than present it on a stage. Although the interest for such forms of devising co-creative musicking within the (elderly) health care sector is growing, the work can be considered relatively new. In terms of research, multiple studies have sought to understand the impact of such work on musicians and participants, however little is known about what underpins the musicians’ actions in these settings. With this study, I sought to address this gap by investigating professional musicians’ emerging practices when devising co-creative musicking with elderly people. Three broad concepts were used as a theoretical background to the study: Theory of Practice, co-creative musicking, and Praxialism. Firstly, I used Theory of Practice to help understand the nature of emerging practices in a wider context of change in the field of music and habitus of musicians and participants. Theory of Practice enabled me to consider a practice as “a routinized type of behaviour which consists of several elements, interconnected to one another: forms of bodily activities, forms of mental activities, ‘things’ and their use, a background knowledge in the form of understanding, know-how, states of emotion, and motivational knowledge” (Reckwitz, 2002, p. 249). Secondly, I drew the knowledge from co-creative musicking, which is a concept I gathered from two existing concepts: co-creation and musicking. Musicking (Small, 1998), which considers music as something we do (including any mode of engagement with music), provided a holistic and inclusive way of looking at participation in music-making. The co-creation paradigm encompasses a view on enterprise that consists of bringing together parties to jointly create an outcome that is meaningful to all (Prahalad & Ramaswamy, 2004; Ramaswamy & Ozcan, 2014). The concept served as a lens to specify the jointness of the musicking and challenge issues of power in the engagement of participants in the creative-productive process. Thirdly, Praxialism considers musicking as an activity that encompasses “musical doers, musical doing, something done and contexts in which the former take place” (Elliott, 1995). Praxialism sets out a vision on music that goes beyond the musical work and includes the meanings and values of those involved (Silverman, Davis & Elliott, 2014). The concept allowed me to examine the work and emerging relationships as a result of devising co-creative musicking from an ethical perspective. Given the subject’s relative newness and rather unexplored status, I examined existing work empirically through an ethnographic approach (Hammersley & Atkinson, 2007). Four cases were selected where data was gathered through episodic interviewing (Flick, 2009) and participant observation. Elements of a constructivist Grounded Theory (Charmaz, 2014) were used for performing an abductive analysis. The analysis included initial coding, focused coding, the use of sensitizing concepts (Blumer 1969 in Hammersley, 2013) and memoing. I wrote a thick description (Geertz, 1973) for each case portraying the work from my personal experience. The descriptions are included in the dissertation as one separate chapter and foreshadow the exposition of the analysis in a next chapter. In-depth study of the creative-productive processes of the cases showed the involvement of multiple co-creative elements, such as a dialogical interaction between musicians and audience. However, participants’ contributions were often adopted implicitly, through the musicians interpreting behaviour and situations. This created a particular power dynamic and challenges as to what extent the negotiation can be considered co-creative. The implicitness of ‘making use’ of another person’s behaviour with the other not (always) being aware of this also triggered an ethical perspective, especially because some of the cases involved participants that were vulnerable. The imbalance in power made me examine the relationship that emerges between musicians and participants. As a result of a closer contact in the co-creative negotiation, I witnessed a contact of a highly personal, sometimes intimate, nature. I recognized elements of two types of connections. One type could be called ‘humanistic’, as a friendship in which there is reciprocal care and interest for the other. The other could be seen as ‘functional’, which means that the relationship is used as a resource for providing input for the creative musicking process. From this angle, I have compared the relationship with that of a relationship of an artist with a muse. After having examined the co-creative and relational sides of the interaction in the four cases, I tuned in to the musicians’ contribution to these processes and relationships. I discovered that their devising in practice consisted of a continuous double balancing act on two axes: one axis considers the other and oneself as its two ends. Another axis concerns the preparedness and unpredictability at its ends. Situated at the intersection of the two axes are the musicians’ intentionality, which is fed by their intentions, values and ethics. The implicitness of the co-creation, the two-sided relationship, the potential vulnerability of participants, and the musicians’ freedom in navigating and negotiation, together, make the devising of co-creative musicking with elderly people an activity that involves ethical challenges that are centred around a tension between prioritizing doing good for the other, associated with a eudaimonic intention, and prioritizing values of the musical art form, resembling a musicianist intention. The results therefore call for a musicianship that involves acting reflectively from an ethical perspective. Doctoral study by Karolien Dons
