The Sustainability of Enterprise Mobility in Pandemic – Do Usage Location, Device Type and Device Ownership Matter?

With the trend of consumerization of IT and technology advancement, enterprise mobility or corporate mobile IT is becoming a necessity for companies to stay competitive and agile. This is especially the case during Covid-19 pandemic period, where employees usually have no choice but to use either their own mobile devices or devices provided by the company to complete daily tasks anytime and anywhere convenient for them. This study explores the effects of usage location (e.g., home/office), device type (e.g. smartphones, tablets, laptops) and device ownership (personal owned/company owned) on productivity and work-to-life conflict. A pilot test was conducted with 114 working employees, and a three-way MANOVA test was used to assess the effects. The results showed that there are significant differences in ownership and device in terms of their effects on work-to-life conflict and productivity; location, however, does not have the same effect on the two dependent variables

Telerehabilitation In The Treatment Of Frozen Shoulder: A Case Report

Background and objectives: Frozen shoulder is a common musculoskeletal condition. Telerehabilitation has seen emerging use in a variety of conditions. This case report aims to investigate the feasibility of adopting telerehabilitation in treating frozen shoulder. Case presentation: A 43-year old female presented with frozen shoulder of insidious onset. She underwent four sessions of physiotherapy. Sessions two and three were telerehabilitation sessions; the initial and final sessions were conducted in-person. Results: The subject was compliant with all exercises prescribed during her rehabilitation and achieved all rehabilitation goals in four sessions. She was then discharged from physiotherapy. Conclusion: Telerehabilitation is feasible in treating frozen shoulder. One barrier to implementation of telerehabilitation includes the lack of technical skills and knowledge despite the high prevalence of technology in today’s society. Telerehabilitation increases accessibility and ease of rehabilitation. Telerehabilitation can be considered for segments of the population that are most inclined to use technology

Predictor control for wave PDE / nonlinear ODE cascaded system with boundary value-dependent propagation speed

summary:This paper investigates predictor control for wave partial differential equation (PDE) and nonlinear ordinary differential equation (ODE) cascaded system with boundary value-dependent propagation speed. A predictor control is designed first. A two-step backstepping transformation and a new time variable are employed to derive a target system whose stability is established using Lyapunov arguments. The equivalence between stability of the target and the original system is provided using the invertibility of the backstepping transformations. Stability of the closed-loop system is established by Lyapunov arguments
