- Control of the crystallization process is central to developing nanomaterials with atomic precision to meet the demands of electronic and quantum technology applications. Semiconductor nanowires grown by the vapor-liquid-solid process are a promising material system in which the ability to form components with structure and composition not achievable in bulk is well-established. Here, we use in situ TEM imaging of Au-catalyzed GaAs nanowire growth to understand the processes by which the growth dynamics are connected to the experimental parameters. We find that two sequential steps in the crystallization process - nucleation and layer growth - can occur on similar time scales and can be controlled independently using different growth parameters. Importantly, the layer growth process contributes significantly to the growth time for all conditions and will play a major role in determining material properties such as compositional uniformity, dopant density, and impurity incorporation. The results are understood through theoretical simulations correlating the growth dynamics, liquid droplet, and experimental parameters. The key insights discussed here are not restricted to Au-catalyzed GaAs nanowire growth but can be extended to most compound nanowire growths in which the different growth species has very different solubility in the catalyst particle.

Evaluating the Impact of Strategies on Students’ Perceptions of Digital Transformation – A Case Study of a Swedish Higher Education Institution

- Digital transformation (DT) in Higher Education Institutions (HEIs) affects the learning environment with digitally-enhanced teaching methods, student assistance, and administration processes. HEIs develop strategies to exploit the chances offered by DT. Our study investigates the connection between the strategic work of HEIs on DT and how students perceive the results of this work in their daily studies. We applied a case study design on a Swedish HEI to gather our results. Results show that students are somewhat positive about the strategic work but still perceive digitalization as a barrier to collaborating with peers and lecturers. Our research contributes to knowing if the time and effort spent on an HEI’s DT impact the student stakeholder group. By bringing forth ways of improvement, we generate new knowledge about DT processes in HEIs. Thus, we inspire educators and administrators in this industry by putting forward lessons learned and improvements.

- Rationale: To maintain patients’ dignity and well-being and alleviate suffering, it is essential that healthcare providers engage in caring behaviours. Yet, every year patient boards receive an increasing number of complaints from patients and significant others regarding healthcare providers’ non-caring behaviours. Defining and measuring both verbal and nonverbal caring and non-caring behaviour in healthcare delivery is vital to address such complaints. However, no studies were found that incorporated a comprehensive theory of caring to code encounters between healthcare providers and patients.Aim: The aim was to develop and test a Caring Behavior Coding Scheme based on Swanson’s Theory of Caring.Method: An instrument development process was used for behavioural coding including observational data from thirty-eight video recordings collected in an undergraduate nursing course at a Swedish University. The observational data involved interactions between undergraduate nursing students and a standardised patient.Result: The Caring Behavior Coding Scheme (the CBCS), contains seventeen verbal and eight nonverbal behavioural codes, categorised as caring and non-caring in accordance with Swanson’s Theory of Caring. Content and face validity were assessed. Timed-event sequential continuous coding was performed in INTERACT software. The coder achieved excellent agreement with the developed gold standard (k = 0.87) and excellent mean inter-rater reliability (k = 0.82). All domains in Swanson’s Theory of Caring were observed and coded in the interaction.Discussion/Conclusion: The CBCS is a theory-based instrument that contributes to research on healthcare providers’ behavioural encounters. It uses verbal and nonverbal caring and non-caring behavioural codes to assess the alignment of both the theory and practice of caring. The CBCS can contribute to both development and measurement of interventions focused on improving healthcare providers’ caring behaviour with the intended outcome of patient well-being.

Experiences of the Redesigning Daily Occupation programme - a qualitative study among persons with neurological diseases

Tidskriftsartikel (refereegranskat)abstract
- Background: The Redesigning Daily Occupations (ReDO) is a programme targeting persons who need to restructure activities and routines to achieve a healthier balance in everyday life. Issues that often is needed for persons with neurological diseases.Aims/Objectives: To describe how persons with neurological disease experienced the ReDo-programme and to investigate how their occupational patterns and fatigue changed during the programme.Material and Methods: A mixed method study with a convergent parallel design including ten participants. Questionnaires and individual semi-structured interviews have been used and data analysed by descriptive statistics and thematic analysis.Results: The findings indicated an increased participation in everyday life after the intervention. Furthermore, the main theme showed that the intervention enabled reflections and new insight. Sub-themes included: feeling pressured to perform, being part of a group and changing occupational pattern.Conclusions: Participants valued being a group; however, they experienced the intensity as being too high. The content of the intervention enabled reflections and new insights regarding their occupational pattern, which was experienced as a starting point towards behavioural changes and re-prioritisation of occupations in everyday life.Significance: A modified version with lower intensity and careful goal setting might be valuable for persons with neurological diseases.
