The impact of wearable devices on employee wellness programs: A study of hotel industry workers

Hospitality workplaces are particularly challenging contexts in which to implement wellness initiatives. The present study implemented a technology-based wellness intervention to improve various aspects of employee wellness in contemporary hotel workplaces. The participants were given a wearable device (Fitbit, used here as an innovative tool) in order to monitor their activity levels and sleep patterns over a 14-day period. Additionally, the participants provided researchers with food diaries in separate electronic form. Information regarding job satisfaction, job engagement, organizational citizenship behaviors, and intention to leave was obtained before and after the observation period. The results demonstrate an increase in physical activity, an increase in healthy food consumption, and a reduction in overall caloric intake. Furthermore, positive changes in employee engagement, job satisfaction, and organizational commitment were noted. Care should be exercised when implementing such interventions in order to ensure data privacy and positive employee relations.

商务英语广告中模糊性语言积极创意及汉译对策

商务英语广告的语言模糊性处理是一种语言挑战,但这种语言运用及其跨语言转换时的积极歧义层面,也为商务英语广告制作及其汉译提供了创意空间。尤其是在修辞格使用与翻译操作中,更应该有意利用这种语言模糊特性的积极面,以追求生动、形象、动感的艺术效果。本文从模糊性语言理论着手,对商务英语广告的修辞格现象进行了分析和论述,并提出了相应的汉译策略。     

Stage-gate process for life sciences and medical innovation investment

Life science innovation has led to significant improvements in clinical outcomes and has been a source of financial growth for individuals and institutions capable of performing appropriate investments in this sector. Several groups have developed methodologies to assist medical technology innovators in the design and development activities. Unfortunately, these tools have not aided the general investment community to profit from these enterprises. This situation has contributed to a general reduction in risk capital directed towards life sciences compared to other industries. We review the current investment practices in the life science sector and present a comprehensive stage-gate model that aims to captures this investment process. An analysis of best practices and in-depth interviews with 68 life sciences investors and entrepreneurs worldwide are used to support such model. A single case-control study comparing life science investment execution within two similar investment firms was conducted to evaluate feasibility in the implementation of these practices. The stage-gate model includes (I) General vision and investment strategy definition; (II) Venture search, screening and rapid pre-evaluation; (III) Due diligence and negotiation of terms; (IV) Portfolio management, evaluation, and exit. The difference in execution of investment and results from a post-performance Root Cause Analysis were consistent with a reduction in perceived risk from the case company trained with the proposed model compared to the control. This suggests that our developed model and process may be useful in encouraging life sciences investment via evidence-based evaluations.
