ABSTRACT In extreme circumstances such as pandemics, the presence of patients in hospital emergency departments becomes untenable. Healthcare professionals and organizations worldwide are leaning on technology as a crucial ally to deal with the COVID-19 outbreak. This article focuses on the positive impact of telemedicine for helping service provision, from enabling virtual triage to mitigating the negative psychological effects of social isolation. The authors discuss the challenges and opportunities to telemedicine practices. 相似文献

PurposeThe COVID-19 pandemic has suddenly brought about a number of disruptions to when and where work is undertaken for hospitality employees. The rapid spread of COVID-19 forced many hospitality managers to use digital technologies to perform work from home, termed digital work connectivity. Yet little is known about how hospitality employees cope with it. The purpose of this study is to investigate an important yet underspecified issue as to how digital work connectivity can be detrimental for employees’ work behavior.Design/methodology/approachWe test our hypotheses using multi-wave and multi-source data collected from 467 middle managerial-level hospitality employees in China.FindingsThe findings show that digital work connectivity can lead to self-control depletion, which in turn is associated with disengagement from work. Further, the findings show that relational energy is an important resource that can buffer the detrimental effects of digital work connectivity on hospitality employees.Practical implicationsThe association of digital work connectivity with employee withdrawal behavior highlights the urgent need for hospitality enterprises to have clear guidelines that regulate technology use at home for work purposes.Social implicationsOur research shows that the absence of clear guidelines in relation to the use of digital technology for work at home risks producing unintended consequences for both hospitality employees and their enterprises.Originality/valueOur research draws from recent advances in resource allocation theories of self-control and adopts a more nuanced approach to uncover a counterintuitive reality that while people use digital technology to remain connected with work, doing so can actually contribute to their withdrawal behavior. 相似文献

基于卡普兰复愈性环境理论,运用脑机接口设备、智能腕带传感器等无线生理指标检测技术,测试大学生被试人群在沉浸式虚拟现实(VR)情境下,对4种复愈性环境及城市环境在注意力恢复和压力减轻方面的反应及其作用强度,获得被试在不同环境中脑电、心率、肌电的客观生理数据。采用非参数统计方法R语言对数据进行分析。结果显示,多数被试在复愈性环境中较城市环境表现出更好的注意力恢复效果。其中具有逃离性和迷人性特征的自然环境,复愈效果最为明显;在虚拟现实环境中,观赏城市环境图片也具有一定的复愈效果。 相似文献

Given the marked heterogeneous conditions in smallholder agriculture in Sub-Saharan Africa, there is a growing policy interest in site-specific extension advice and the use of digital extension tools to provide site-specific information. Empirical ex-ante studies on the design of digital extension tools and their use are rare. Using data from a choice experiment in Nigeria, we elicit and analyze the preferences of extension agents for major design features of ICT-enabled decision support tools (DSTs) aimed at site-specific nutrient management extension advice. We estimate different models, including mixed logit, latent class and attribute non-attendance models. We find that extension agents are generally willing to use such DSTs and prefer a DST with a more user-friendly interface that requires less time to generate results. We also find that preferences are heterogeneous: some extension agents care more about the effectiveness-related features of DSTs, such as information accuracy and level of detail, while others prioritise practical features, such as tool platform, language and interface ease-of-use. Recognising and accommodating such preference differences may facilitate the adoption of DSTs by extension agents and thus enhance the scope for such tools to impact the agricultural production decisions of farmers. 相似文献

The purpose of the present study is to incorporate geographic analysis of FDI into the classic IDP model. By supplementing the traditional analysis of the net outward investment (NOI) position with an analysis of geographic patterns in inward and outward FDI, the authors strive to offer a better explanation of Poland’s current NOI position and provide more in-depth support to some necessary policy recommendations. Hence the main contribution of this study to the international business scholarship is two-fold. It (1) further develops the IDP research methodology; and (2) provides a better understanding of the idiosyncratic nature of the IDP of Poland. 相似文献

科技创新是立国之本、强国之路。政府在不同阶段制定相应的科技政策,以求持续激励企业参与创新活动、提高企业核心竞争力、促进产业结构转型升级。基于广东省2005-2017年上市公司数据,采用计数模型实证分析了地级市政府科技政策对企业创新的影响及作用机制。研究表明:科技政策力度越大,越能提高企业的创新水平;科技政策的激励作用主要通过研发强度这一中介变量产生;科技政策不仅能促进企业的策略性创新行为,同时也会导致企业的实质性创新行为;直接激励类型的政策对企业创新并无显著影响,而营造创新氛围的间接激励类型政策则对企业创新有着显著的正向影响;政策激励对非国有企业、非高科技企业的正向作用更加明显。 相似文献
