Social media emerged as a primary source of information among young users, but its severe effect on mental state due to information overload, still an area of concern for the researchers. Generation Z users' addiction to the mobile phone/gadgets is increasing with a rise in social media and consequently their behavioral outcomes have transformed completely. Nowadays behavioral issues including stress, fatigue, ‘fear of missing out’ and ‘phubbing’, anxiety etc. rising each day but the relationship among these issues and information overload is less examined. The social media users are unable to filter the trustworthy information due to its enormous size and thus role of information support from government becomes essential. The current study extends the S-O-R theory exploring relationship between the stimulus of enormous information on the responses generated among the Generation Z such as social media fatigue, ‘fear of missing out’, ‘phubbing’ and anxiety. The findings from a sample of 319 users belonging to Generation Z suggest that social media platforms need to understand user's compulsive usage that is resulting into fatigue and consequently anxiety. The role of government information support on reducing fatigue and anxiety is found to be positive. The relationship between ‘fear of missing out’, ‘phubbing’ and anxiety is found significant and shows presence of partial mediation. The study offers significant theoretical and practical implications. It is significant for the service providers and social media platforms to advance interfaces with minimum fatigue for the users and offers information support to the users to reduce stress caused by information load.  相似文献

近年来,劳动力价格的快速上涨已然成为中国农业生产所必须面对的内在挑战。对于机械作业难度相对较大的劳动密集型作物而言,在缓解劳动力约束瓶颈的同时,更应通过精细化的果园管理,以提高产品质量,进而提高其市场价格。然而,由于农产品具有典型的经验品属性,在信息不对称的外部约束下,农户通常难以获得应有的"质量溢价"。基于此,本文通过构建理论分析框架,以果品质量关键环节的精细管理技术作为研究对象,系统分析在劳动力价格上涨背景下农户精细管理技术投入的决策机制,以及在不同农产品质量识别程度中,劳动力成本变化对其影响的异质性,并基于全国18个省份农户的调研数据进行实证研究。研究结果表明:农户交易对象质量识别能力的提高,能够缓解农户与购买者之间存在的信息不对称性,将农产品质量信息传递给购买者,使农户获得更高的销售价格,进而在有效提高农户精细管理技术投入水平的同时,能够弱化劳动力价格对其所产生的负面影响。  相似文献

When the pandemic struck and teaching went online worldwide, universities had to make pressing decisions that balanced cybersecurity against other factors, including health and safety, usability, and cost. One such challenge Indiana University (IU) faced was how to accommodate the secure telecommunications needs of 130,000 faculty, staff, and students who would now be teaching, learning, doing research, and working from home. Some universities reflexively promoted virtual private network (VPN) use for all activities. Such an approach would have been unsustainable at IU, however, owing both to the licenses and resources needed for the sheer number of users and to the high-throughput applications on which they rely. Perhaps even worse, it would have increased the chances that the VPN would be unavailable during a critical incident or other situation in which secure communications must be guaranteed. Instead, IU launched an awareness campaign demonstrating exactly when VPN use is and isn’t needed. In addition, network staff employed a VPN feature called split tunneling to reduce the load. This article discusses the advantages and disadvantages of this approach and how IU made the decision to balance both sides of the risk equation to ensure the continued advancement of its mission throughout the pandemic.  相似文献

Due to the paucity of sources of negative firm‐specific information, US capital markets have more difficulty identifying and incorporating bad news into stock prices than they do good news. Even though insider selling is a potentially important proxy for undisclosed bad news, researchers have difficulty ex ante identifying information‐based sales due to an inability to separate liquidity‐motivated from information‐based insider trades. We hypothesize that when insiders in multiple firms sell shares of one firm in which they are insiders and at the same time buy shares of other insider portfolio firms, the sale is more likely to be information‐based, since the proceeds are reinvested. Conversely, when an insider sells one firm without purchasing others or sells multiple insider firms the sale is likely liquidity‐motivated. We find that insider sales identified as information‐based using this algorithm are followed by significant negative abnormal returns. Information‐based sales are also more likely to be associated with delistings, earnings declines and earnings restatements. Analysts are also more likely to revise their earnings forecasts downwards for these firms. It is thus possible to ex ante identify insider sales with information content. Our results will be of interest to investors and also to regulators designing insider trading rules.  相似文献

我国于2012年实现了社会保障在制度上的全覆盖。然而,对于自愿参与型社会保障项目,政策目标人群的参保率过低,无法充分发挥社会保障体系的风险分担和福利保障作用。2020年,党的十九届五中全会将健全社会保障体系作为“十四五”时期经济社会发展主要目标之一。分析政策目标人群的参保决策,有针对性地提高群众参保率,对于充分发挥社会保障制度的功能和健全社会保障体系具有重要意义。本文以新型农村社会养老保险(新农保)为例,使用家庭调查数据和工具变量方法,考察同群效应在社会保障项目参与决策中的作用。研究发现:同村居民参与新农保的比例每增加10个百分点,个体参保概率显著增加4.24个百分点;同村居民之间的信息传递以及其内部形成的社会规范是同群效应发挥作用的重要渠道;男性的参保行为具有更强的示范效应。本文的研究结论表明,加强基层政策宣传和提高政策透明度,以及有针对性地提高特定群体的参保率是提高社会保障项目整体参与率的有效手段。  相似文献

Online travel agencies (OTAs) allow lodging businesses to select one cover photograph to represent itself on the OTA site. The cover photograph plays a crucial role for attracting customers’ attention from among alternatives, and lure viewers to view the webpage with detailed information. The present study investigates how the content of a business’ cover photograph on OTAs’ sites influences customers’ behavior when searching for information. The content of a cover photograph may fall within five categories according to attributes: façade, type of place, room amenities, scenery, and property amenities. Only façade and property amenities have positive impacts on customers’ viewing times of the webpages with the detailed information of businesses. In contrast, scenery has a negative influence on customers’ viewing times. The results of the study contribute, theoretically and methodologically, to OTAs’ knowledge base and can assist practitioners’ identification of effective cover photographs.  相似文献

Metaverse is the next disruptive technology that will impact society in the coming decades, by enabling immersive experiences in both virtual and physical environments. Although still conceptual, Metaverse converges the physical and digital universe, allowing users to seamlessly traverse between them. Digital immersion offers opportunities for people to travel in time, supporting users to experience virtually ancient encounters, space explorations or dangerous natural phenomena, such as volcano eruptions. Users can explore immersive environments for working, learning, transacting, exploring interests and socialising with others. This is already evident in gaming ecosystems, where gamers effectively interact in the metaverse. Although still experimental, Metaverse is expected to revolutionize travel and tourism management and marketing. It empowers destination awareness, positioning and branding, as well as coordination and management, through digital twins. Metaverse provides opportunities to support trip planning, interaction and engagement, effectively transforming consumer behaviour. Visiting and engaging with destinations virtually is expected to motivate real travel, rather than replace it. This paper provides a vision of how Metaverse can revolutionize tourism experiences and transform tourism management and marketing. Drawing on a systematic review of scholarly works, articles from media and industry reports, this study defines and conceptualizes the Metaverse ecosystem for tourism and travel. It explores the foundations of the disruptions that Metaverse brings to tourism destinations and organisations and identifies the building blocks of Metaverse tourism. The study outlines research directions so that the tourism industry can take full advantage of the Metaverse capabilities and opportunities emerging as well as identify challenges for the future.  相似文献

Research Summary: We study the use of corporate philanthropy as a form of reputation insurance, developing a formal model of such insurance to examine how the terms of insurance in equilibrium change under different assumptions about the firm and its stakeholders. We then test the predictions from this model in the U.S. petroleum industry and find that philanthropic donations offer insurance‐like benefits, but are also positively associated with subsequent oil spills—firms that give more, spill more—with this association being stronger for spills that are under firms’ control and in states with low civic capacity. These results are consistent with an adverse selection/moral hazard equilibrium and suggest that the use of philanthropy as reputation insurance may benefit firms at the cost of society. Managerial Summary: Firms that donate to social causes develop a reputation for being socially responsible, and are often given the benefit of doubt when negative information about them comes to light. But are philanthropic firms truly more responsible? We argue that firms that donate more may be more likely to do harm—those that expect to do harm later are likely to give more now, and those that know their reputation protects them may become less careful. Evidence from the U.S. petroleum industry is consistent with this argument, with firms that give more having more subsequent oil spills, but only the type of spills that are under the firm's control, and only in states where the firm faces weaker scrutiny.  相似文献

Demand forecasting is critical to sales and operations planning (S&OP), but the effects of sales promotions can be difficult to forecast. Typically, a baseline statistical forecast is judgmentally adjusted on receipt of information from different departments. However, much of this information either has no predictive value or its value is unknown. Research into base rate discounting has suggested that such information may distract forecasters from the average uplift and reduce accuracy. This has been investigated in situations in which forecasters were able to adjust the statistical forecasts for promotions via a forecasting support system (FSS). In two ecologically valid experiments, forecasters were provided with the mean level of promotion uplift, a baseline statistical forecast, and quantitative and qualitative information. However, the forecasters were distracted from the base rate and misinterpreted the information available to them. These findings have important implications for the design of organizational S&OP processes, and for the implementation of FSSs.  相似文献
