Engineered bioactive glass-chitosan hybrid for dual tissue and bone regeneration multifunctional healing
No full textThe treatment of complex wounds, particularly those arising from conditions such as diabetes or trauma, presents a significant clinical challenge. These wounds often necessitate long-term care for soft tissue and bone repair, creating an urgent need for multifunctional wound dressings. This study introduces a chitosan-silica hybrid dressing enhanced with bioactive glass (BG), specifically designed to address this need. The hybrid material achieves molecular bonding through coupling agents, with the organic chitosan component providing swelling and hemostatic effects, while the inorganic silica and BG release ions (Si4+, Ca2+), promoting tissue regeneration and bone healing. With a controlled degradation profile (lasting 3 to 6 months in-vitro), the dressing is ideal for chronic wound management. Experimental results demonstrate excellent biocompatibility, no inflammatory response, and strong hemostatic properties due to the positively charged chitosan and cations. Adding BG significantly enhances bone regeneration, positioning this chitosan-silica hybrid as a promising solution for the simultaneous repair of soft tissue and bone
Minimizing hotel employees’ negative responses to adverse change practices: The application of attribution theory
No full textHospitality organizations need to make changes from time to time, which usually result in adverse human
resource (HR) practices, such as readjustments to job duties or salary cuts. To reduce negative employee responses to these adverse practices, scholars suggest the important role of change communication. However, it
remains unclear how change communication can alter employees’ cognition to minimize their negative responses. Drawing on the HR attribution theory, we hypothesize that high-quality change communication can
reduce employees’ turnover intentions through well-being attribution. We further argue that this indirect effect
depends on the seriousness of the negative impact on employees. We test this moderated mediation model with
two waves of time-lagged data from 223 employees of a hotel in Hong Kong when it had to implement a no-pay
leave program due to a renovation project. The results provide support for our proposed model. Important
implications for hotel practitioners are discussed
