Background A low-cost virtual reality system that translates movements of the hand, fingers, and thumb into game play was designed to provide a flexible and motivating approach to increasing adherence to home-based rehabilitation. Objective Effectiveness depends on adherence, so did patients use the intervention to the recommended level? If not, what reasons did they give? The purpose of this study was to investigate these and related questions. Design A prospective cohort study, plus qualitative analysis of interviews, was conducted. Methods Seventeen patients recovering from stroke recruited to the intervention arm of a feasibility trial had the equipment left in their homes for 8 weeks and were advised to use it 3 times a day for periods of no more than 20 minutes. Frequency and duration of use were automatically recorded. At the end of the intervention, participants were interviewed to determine barriers to using it in the recommended way. Results Duration of use and how many days they used the equipment are presented for the 13 participants who successfully started the intervention. These figures were highly variable and could fall far short of our recommendations. There was a weak positive correlation between duration and baseline reported activities of daily living. Participants reported lack of familiarity with technology and competing commitments as barriers to use, although they appreciated the flexibility of the intervention and found it motivating. Limitations The small sample size limits the conclusions that can be drawn. Conclusions Level of use is variable and can fall far short of recommendations. Competing commitments were a barrier to use of the equipment, but participants reported that the intervention was flexible and motivating. It will not suit everyone, but some participants recorded high levels of use. Implications for practice are discussed.

Virtual reality has become a promising field in recent decades, and its potential now seems clearer than ever. With the development of handheld devices and wireless technologies, interest in virtual reality is also increasing. Therefore, there is an accompanying interest in inertial sensors, which can provide such advantages as small size and low cost. Such sensors can also operate wirelessly and be used in an increasing number of interactive applications. An example related to virtual reality is the ability to move naturally through virtual environments. This is the objective of the real-walking navigation technique, for which a number of advantages have previously been reported in terms of presence, object searching, and collision, among other concerns. In this article, we address the use of foot-mounted inertial sensors to achieve real-walking navigation in a wireless virtual reality system. First, an overall description of the problem is presented. Then, specific difficulties are identified, and a corresponding technique is proposed to overcome each: tracking of foot movements; determination of the user’s position; percentage estimation of the gait cycle, including oscillating movements of the head; stabilization of the velocity of the point of view; and synchronization of head and body yaw angles. Finally, a preliminary evaluation of the system is conducted in which data and comments from participants were collected.

BACKGROUND: As the COVID-pandemic has shown, the need for innovative (digitalized) solutions is in high demand across almost every field of interest. The implementation of advanced technologies in higher education provides an intriguing opportunity to expand its scope by reaching new audiences as well as ensuring a high quality of learning outcome. OBJECTIVE: In this article we tried to examine if virtual reality can be a suitable option by placing lectures into a virtual setup. METHODS: First, we explored the theoretical background if and how virtual reality has been adapted for usage in higher education. We then asked five lecturers from the IMC University of Applied Sciences Krems to test a virtual environment (Mozilla Hubs) and evaluate the platform for their teaching purposes. RESULTS: Among one of the results was, that 80 percent would recommend using the platform for lectures to their colleagues. Due to the small sample size the findings need to be further evaluated. CONCLUSIONS: In the foreseeable future virtual reality will become a valuable teaching assistance in higher education. Findings show that the response rate when training with virtual reality applications is much higher than to common studying methods.

Interactive simulation in automotive driving has enhanced the studies of driver behaviors, traffic control, and vehicle dynamics. The development of virtual reality (VR) technology leads to low cost, yet high fidelity, driving simulator become technically feasible. However, a good implementation of high realism and real-time interactive three-dimensional (3D) virtual environment (VE) in an automotive driving simulation are facing many technical challenges such as accessibility, dissimilarity, scalability, and sufficiency. The objective of this paper is to construct a virtual reality system for an automotive driving simulator. The technology with variations of terrain, roadway, buildings, and greenery was studied and developed in the VE of the simulator. Several important technical solutions in the construction of VE for driving simulation had been identified. Finally, the virtual reality system was interactively used in a driver-in-loop simulation for providing direct road elevation inputs to the analysis of vehicle dynamics model (VDM). The results indicated identical matching between the VDM inputs and the VE outputs. The outcomes of this paper lead to a human-in-the-loop foundation of a low-cost automotive driving simulator in the vehicle engineering research.

BACKGROUND DNA methylation of the differentially methylated regions (DMRs) of imprinted genes is relevant to neurodevelopment. METHODS DNA methylation status of the DMRs of nine imprinted genes in umbilical cord blood leukocytes was analyzed in relation to infant behaviors and temperament (n = 158). RESULTS MEG3 DMR levels were positively associated with internalizing ( β = 0.15, P = 0.044) and surgency ( β = 0.19, P = 0.018) behaviors, after adjusting for birth weight, gender, gestational age at birth, maternal age at delivery, race/ethnicity, education level, smoking status, parity, and a history of anxiety or depression. Higher methylation levels at the intergenic MEG3-IG methylation regions were associated with surgency ( β = 0.28, P = 0.0003) and PEG3 was positively related to externalizing ( β = 0.20, P = 0.01) and negative affectivity ( β = 0.18, P = 0.02). CONCLUSION While the small sample size limits inference, these pilot data support gene-specific associations between epigenetic differences in regulatory regions of imprinted domains at birth and later infant temperament.

Purpose The purpose of this paper is to determine the extent of voluntary corporate social responsibility (CSR) disclosure by Indonesian firms on their social media and to compare it with the mandatory disclosure on their annual reports. Design/methodology/approach The authors use publicly listed Indonesian firms that are included in the SRI-KEHATI Index as the sample. Further, by using NVIVO software, the authors qualitatively analyze CSR activities disclosed on firms’ social media and annual reports with an interpretive approach. Findings The findings indicate that Indonesian firms still exhibit early stages of social media-based voluntary CSR disclosure. Further, issues on training, education and skill building dominate firms’ disclosure. Finally, Indonesian firms disclose less CSR information in their social media than in their annual reports, thus confirming the early stages of social media-based CSR disclosure. Research limitations/implications The small sample size limits the generalizability of the results. Practical implications This paper provides insights on which CSR issues are commonly disclosed in firms’ social media. This study may also inform regulators the extent of disclosures that could be regulated in social media. Originality/value Social media-based CSR disclosure in developing countries is relatively understudied. Thus, this paper empirically shows the topic and intensity of CSR disclosure in social media and the comparison between this type of CSR disclosure with CSR disclosure using other media.

Practical Implications

Purpose – The purpose of this paper is to present a research from a study undertaken with Methodist circuit ministers in the UK and those that work closely with them. It considers in what way and to what extent ministers think of themselves as managers and to what extent and in what way they are expected to perform as managers by those they work with. Design/methodology/approach – The research that informs this paper was gathered through a qualitative study which involved in-depth semi-structured interviews with 22 participants both Methodist ministers and those who worked closely with them. Findings – The study shows that, whilst those who work with ministers typically do not problematize management and expect managers to be able to perform management tasks, the ministers themselves are ambiguous about or rejecting of the discourse of management. Research limitations/implications – The relatively small sample size limits generalizability. Practical implications – The study challenges trainers in this context and in other contexts where the “language” of management is contested or rejected to find a discourse of management which is acceptable. Originality/value – The study contributes to the small body of literature on management and the development of managers within religious organizations. It contributes to the literature on managerial identity and the importance of management language in becoming a manager by presenting an example where this language and identity is contested or rejected.
