Online social networks allow for information to rapidly propagate throughout the world, and opinions expressed on such platforms can influence people’s decisions. During the COVID-19 pandemic, many influential public figures used these social networks to share their opinions about the vaccines developed to combat the virus. Many influencers encouraged vaccination, and a considerable number also expressed doubt and skepticism over the efficacy of the vaccines. This study modeled the impact that eleven influencers’ statements had on the overall sentiment towards COVID-19 vaccines, as expressed on Twitter. Sentiment is measured by collecting a series of publicly-available tweets made regarding the vaccine during the pandemic, and assigning each a sentiment score based on the VADER lexicon. Several models were used to analyze the impact of the influencers’ statements, including linear, sequential and tree-based models. The results were obtained by constructing a Bayesian structural time series model based on each model’s counterfactual estimate. The results found that influencers who share messages encouraging vaccination generally tend to increase the number of ”pro-vaccination” tweets over the next 20 days. Influencers sharing ”anti-vaccination” messages sometimes resulted in a decrease in anti-vaccine tweets, and other times in an increase over the next 20 days. The results from this study provide an introductory look into the complex issue of vaccine hesitancy and the effect of influencers on vaccine messaging, and inform public health strategy regarding this issue.
在线社交网络可使信息迅速传播到世界各地,而在此类平台上发表的意见可影响人们的决策。在 COVID-19 大流行期间,许多有影响力的公众人物利用这些社交网络分享他们对为抗击病毒而开发的疫苗的看法。许多有影响力的人鼓励人们接种疫苗,也有相当多的人对疫苗的功效表示怀疑和怀疑。本研究模拟了 11 位影响者的言论对 Twitter 上人们对 COVID-19 疫苗的整体情绪所产生的影响。情绪的测量方法是收集一系列在大流行期间公开发布的有关疫苗的推文,并根据 VADER 词典为每条推文分配一个情绪分值。分析影响者言论的影响时使用了多种模型,包括线性模型、序列模型和树状模型。结果是根据每个模型的反事实估计值构建贝叶斯结构时间序列模型得出的。结果发现,分享鼓励疫苗接种信息的影响者通常倾向于在接下来的 20 天内增加 "支持疫苗接种 "的推文数量。分享 "反疫苗接种 "信息的影响者有时会减少反疫苗接种推文的数量,有时则会在接下来的 20 天内增加。这项研究的结果对疫苗接种犹豫这一复杂问题以及影响者对疫苗信息传播的影响进行了初步探讨,并为有关这一问题的公共卫生策略提供了参考。

Healthcare Value Chain and the Impact of Analytics & BI 医疗保健价值链与分析和商业智能的影响
Pub Date : 2024-03-25 DOI: 10.17705/3jsis.00033
Rudolph T. Bedeley, Lakshmi Iyer
This study aims to investigate how the existing healthcare value chain system has significantly been impacted as a result of the increasing adoption and implementation of analytics and business intelligence (A&BI) capabilities. Given the increasing interest and investment in A&BI, it is important to have a good understanding of what A&BI capabilities healthcare organizations are utilizing to enhance value. Based on extensive search of the literature and a follow-up case study of a large regional hospital, it was found that the existing healthcare value chain (HCVC) framework is outdated and no longer effective. We therefore revised and updated the existing framework to meet the current needs of modern healthcare practices. Moreover, A&BI applications currently being deployed in healthcare organizations were identified and mapped onto the revised framework. The study contributes by illustrating how healthcare organizations currently utilize or should be using A&BI capabilities to enable them close the quality gaps.
本研究旨在探讨现有的医疗价值链系统如何因越来越多地采用和实施分析与商业智能(A&BI)功能而受到重大影响。鉴于人们对 A&BI 的兴趣和投资日益增加,我们有必要充分了解医疗机构正在利用哪些 A&BI 功能来提升价值。基于对文献的广泛搜索和对一家大型地区医院的后续案例研究,我们发现现有的医疗保健价值链(HCVC)框架已经过时,不再有效。因此,我们对现有框架进行了修订和更新,以满足现代医疗实践的当前需求。此外,我们还确定了目前在医疗机构中部署的 A&BI 应用程序,并将其映射到修订后的框架中。这项研究通过说明医疗机构目前如何利用或应该如何利用 A&BI 功能来缩小质量差距,从而做出了贡献。

Utilizing Social Networks to Improve Success Metrics in Social E-Commerce 利用社交网络改进社交电子商务的成功指标
Pub Date : 2024-03-25 DOI: 10.17705/3jsis.00035
R. DaSouza, E. M. Church
Social e-commerce highlights the current trend of companies strategically using a multi-platform approach for their marketing plans and selling needs. This approach often consists of a company utilizing one or more social networks, along with a social e-commerce, to create an online community around their products. However, there is limited holistic research on how companies use social networks to maximize their branding and marketing efforts. This study theorizes the strategic social network actions of a social e-commerce platform. We collected data from a random sample of 1,458 social e-commerce users and their chosen social networks, including Instagram, Pinterest, Facebook, and X (formerly known as Twitter). This unique data set and analysis assessed the impact of social network marketing from firms across a wide variety of industries and platforms. The study provides empirical evidence on follower growth and sales and identifies impactful marketing strategies in a multi-platform web environment.
社交电子商务凸显了当前企业战略性地使用多平台方法来满足其营销计划和销售需求的趋势。这种方法通常包括公司利用一个或多个社交网络,再加上社交电子商务,围绕其产品创建一个在线社区。然而,关于企业如何利用社交网络最大限度地提升品牌和营销效果的整体研究还很有限。本研究对社交电子商务平台的社交网络战略行动进行了理论分析。我们随机抽样收集了 1458 名社交电商用户及其选择的社交网络(包括 Instagram、Pinterest、Facebook 和 X(前身为 Twitter))的数据。这一独特的数据集和分析评估了社交网络营销对各行各业公司和平台的影响。该研究提供了有关追随者增长和销售额的实证证据,并确定了多平台网络环境中具有影响力的营销策略。

The Impact of Choice Overload on Decision Deferral in Cybersecurity 选择过多对网络安全决策延迟的影响
Pub Date : 2023-11-02 DOI: 10.17705/3jsis.00032
Cristian Alecse
Since a large area of cybersecurity research is technically centered but most cyber incidents are human enabled (Nobles, 2018), a shift in focus towards behavioral issues is imperative to improve the understanding of these problems. Research in behavioral economics shows that cognitive biases can impact the decision-making process. For example, a seminal study conducted by Iyengar and Lepper (2000) reveals that a large array of product options attracted customers to browse, but fewer choices got them to buy. Similar research shows that when presented with a large array of options, customers tend to defer decisions, search for alternatives, or even opt not to choose (Dhar, 1997; Shafir, Simonson and Tversky, 1993). Choice overload bias, also known as over-choice, choice paralysis, or the paradox of choice, describes how individuals get overwhelmed when presented with a large number of options to choose from. While we tend to assume that more choice is a good thing (Ryan and Deci, 2001), behavioral economics related research has shown that people have a harder time choosing from a larger array of options (Chernev, Böckenholt and Goodman, 2015). This study translates extant behavioral economics based research on choice overload from various disciplines (e.g., business, public administration, medical science, sociology) and explores its impact on cybersecurity.
由于网络安全研究的很大一部分以技术为中心,但大多数网络事件都是人为造成的(Nobles,2018 年),因此必须将重点转向行为问题,以增进对这些问题的理解。行为经济学的研究表明,认知偏差会影响决策过程。例如,Iyengar 和 Lepper(2000 年)进行的一项开创性研究显示,大量的产品选项会吸引客户浏览,但较少的选择会让他们购买。类似的研究表明,当面对大量选择时,顾客往往会推迟做出决定,寻找替代品,甚至选择不做选择(Dhar,1997;Shafir、Simonson 和 Tversky,1993)。选择超载偏差,也被称为过度选择、选择瘫痪或选择悖论,描述了个人在面对大量可选项时如何不知所措。虽然我们倾向于认为更多的选择是件好事(Ryan 和 Deci,2001 年),但行为经济学的相关研究表明,人们很难从更多的选项中做出选择(Chernev、Böckenholt 和 Goodman,2015 年)。本研究将不同学科(如商业、公共管理、医学、社会学)现有的基于行为经济学的选择超载研究转化为现实,并探讨其对网络安全的影响。

This study utilizes an explanatory sequential mixed-methods design to examine the impact of COVID-19 on the career trajectories of information technology (I.T.) graduate students and professionals of color. Building on individual differences theory in the initial quantitative phase, data from a national survey of 356 STEM graduate students and professionals of color (Black, Indigenous, and Latino) were analyzed to investigate intersectional differences among I.T. and non-I.T. STEM graduate students and professionals by race/ethnicity, gender, and socio-economic characteristics. Findings suggest differential impacts of COVID-19 on I.T. graduate students and I.T. professionals. Among STEM graduate students, financial strain significantly affected their career plans, whereas among professionals, gender was a significant predictor. Qualitative evidence from I.T. respondents clarified quantitative findings. I.T. graduate students (n=239) were more concerned about research setbacks and career instability, while I.T. professionals (n=117) were concerned with setbacks in professional roles and networks, work/life stability, and increased desires for entrepreneurship.
本研究采用解释性顺序混合方法设计来检验COVID-19对信息技术(it)研究生和有色人种专业人员职业轨迹的影响。在初始定量阶段的个体差异理论的基础上,对356名STEM研究生和有色人种(黑人、土著和拉丁裔)专业人士的全国调查数据进行了分析,以调查it和非it之间的交叉差异。按种族/民族、性别和社会经济特征分类的STEM研究生和专业人员。研究结果表明,COVID-19对it研究生和it专业人员的影响是不同的。在STEM研究生中,经济压力显著影响他们的职业规划,而在专业人士中,性别是显著的预测因子。来自it受访者的定性证据澄清了定量结果。it研究生(n=239)更关心研究挫折和职业不稳定,而it专业人员(n=117)更关心职业角色和网络挫折、工作/生活稳定性和创业欲望增加。

The Persistent Digital Divide: The Case Study of a Minority Serving Institution 持续的数字鸿沟:一个少数民族服务机构的案例研究
Pub Date : 2022-06-17 DOI: 10.17705/3jsis.00025

The COVID-19 pandemic has laid bare the persistent digital divide between those that have access to technology and those that do not. As such, we conducted a case study that consisted of interviews and a survey of students along with interviews of administrators and faculty at a minority serving institution. The institution is used along with resources and appropriations theory as a lens to further understand the digital divide and how technology access and use have manifested during the pandemic. The results suggest that students perceived difficulty with access to and use of information communication technologies (such as hardware and software), which interfered with their engagement with learning. At the institution under investigation, the pre-pandemic lack of access to technological resources was eliminated during the pandemic thanks to additional funding. Nevertheless, the communication problems between the administration and students limited students’ access to the resources available.
2019冠状病毒病大流行暴露了能够获得技术的人和无法获得技术的人之间持续存在的数字鸿沟。因此,我们进行了一个案例研究,包括对少数民族服务机构的学生进行采访和调查,以及对管理人员和教师的采访。该机构与资源和拨款理论一起被用作进一步了解数字鸿沟以及大流行期间技术获取和使用情况的镜头。结果表明,学生在获取和使用信息通信技术(如硬件和软件)方面感到困难,这干扰了他们的学习。在接受调查的机构,由于获得了额外资金,大流行期间消除了大流行前无法获得技术资源的问题。然而,管理部门和学生之间的沟通问题限制了学生对现有资源的使用。

With the declaration of COVID-19 as a pandemic by the World Health Organization and associated public health concerns and emergency measures, the lives of many came to a grinding halt. Whether due to stay-at-home orders and lockdowns, or quarantines, many were required to change their day-to-day way of life overnight. This not only changed the mechanical activities performed daily, such as driving to the office, going out to a restaurant, or attending a party, but this also changed the resultant implications of the utility we received from those activities. Utility theory posits that individuals choose what activities to perform based on some utility function, where the utility satisfies some need. As these activities to meet existing needs were disrupted, we seek to use this as an opportunity to explore how contribution in open-source communities changed, specifically the English Wikipedia. We utilize a natural experiment methodology, centered around the COVID-19 pandemic, and explore contribution patterns before and after the pandemic. Our project will contribute to the understanding of IS during unusual times, specifically in the context of open-source communities that rely on volunteer time and effort.
随着世界卫生组织宣布COVID-19为大流行,以及相关的公共卫生关切和紧急措施,许多人的生活戛然停止。无论是由于居家令、封锁还是隔离,许多人都被要求在一夜之间改变他们的日常生活方式。这不仅改变了日常的机械活动,比如开车去办公室,去餐馆,或者参加聚会,而且这也改变了我们从这些活动中获得的效用的最终含义。效用理论认为,个人根据某种效用函数来选择从事什么活动,在这种效用函数中,效用满足了某种需要。由于这些满足现有需求的活动被打乱了,我们试图以此为契机来探索开源社区的贡献是如何变化的,特别是英文维基百科。我们采用自然实验方法,以COVID-19大流行为中心,探索大流行前后的贡献模式。我们的项目将有助于在不寻常的时期理解IS,特别是在依赖志愿者时间和努力的开源社区的背景下。

Traditionally software products have been classified as utilitarian or hedonic based on the value they provide to the users. In this cross-disciplinary study, we introduce another category of software products called social products i.e., those which provide symbolic value to its users. However, we also suggest these three types of software products are ideal types. In reality, most software products are likely hybrid. They provide differing magnitude of all three values: Utilitarian, Hedonic and Social. We use the different levels (high, medium, and low) of these three values to classify products as predominantly Utilitarian, predominantly Hedonic, predominantly Social and five types of Hybrids. This classification of products offers a fresh perspective into how users view different products in terms of the value they provide to them. The insights from the study can be used to assess software product positioning and to develop suitable product development strategies.
传统上,软件产品根据其为用户提供的价值被分为实用主义和享乐主义两类。在这个跨学科的研究中,我们引入了另一类被称为社会产品的软件产品,即那些为其用户提供象征价值的产品。然而,我们也建议这三种类型的软件产品是理想类型。实际上,大多数软件产品可能是混合型的。它们提供了三种价值的不同程度:功利主义、享乐主义和社会主义。我们使用这三种价值的不同水平(高、中、低)将产品分为以功利为主、以享乐为主、以社交为主和五种混合类型。这种产品分类提供了一个全新的视角,让我们了解用户如何根据产品提供给他们的价值来看待不同的产品。该研究的见解可用于评估软件产品定位,并制定合适的产品开发策略。

The insights from the study can be used to assess software product positioning and to develop suitable product development strategies.","PeriodicalId":186837,"journal":{"name":"The Journal of the Southern Association for Information Systems","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123798430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The COVID-19 pandemic has been a hectic time for faculty at the higher education and K-12 levels. With many institutions having to switch to remote learning, faculty had to find tools and resources that could be used to create virtual educational communities. In this milieu of remote learning, the technology tools must foster a thriving educational environment and facilitate communications. In the undergraduate Cybersecurity and Network Management (CNM) program at Murray State University (MSU), the faculty adopted Discord for teaching classes, lab work, and for social events. Discord has been used by the CNM faculty for over a year now and has shown positive results. Students like using Discord for streamlining the communication process and for having the ability to establish real time communication with faculty. In this paper, the authors present their approach to developing and managing the use of Discord in the CNM program at MSU.
COVID-19大流行对高等教育和K-12级别的教师来说是一个忙碌的时期。随着许多机构不得不转向远程学习,教师们不得不寻找可用于创建虚拟教育社区的工具和资源。在这种远程学习的环境中,技术工具必须营造一个繁荣的教育环境,促进交流。在默里州立大学(MSU)的本科生网络安全和网络管理(CNM)项目中,教师们在教学、实验室工作和社交活动中使用了Discord。CNM教师使用Discord已经一年多了,并取得了积极的成果。学生们喜欢使用Discord来简化沟通过程,并有能力与教师建立实时沟通。在本文中,作者介绍了他们在密歇根州立大学CNM项目中开发和管理Discord使用的方法。

Social media has had a huge impact on how we live and interact as a society. Yet, research literature is sparse on the psychology of users who participate enthusiastically in the social media. In this exploratory study with 222 student users we apply the theory of fundamental human needs to predict and assess the psychological profile of users who actively engage in social media. Overall the finding of the study support our hypothesis but with a few unexpected findings. Need of relationship, self-esteem and popularity-influence were found to positively impact the behavioral intention, frequency and time users spent on social media. The findings have useful practical implications for product/ project managers in understanding what motivates users to engage in social media and how social media can be designed to further enhance user participation.
社交媒体对我们作为一个社会的生活和互动方式产生了巨大的影响。然而,关于热心参与社交媒体的用户心理的研究文献很少。在这项针对222名学生用户的探索性研究中,我们运用人类基本需求理论来预测和评估积极参与社交媒体的用户的心理特征。总的来说,这项研究的发现支持了我们的假设,但也有一些意想不到的发现。人际关系需求、自尊和人气影响对用户使用社交媒体的行为意向、频率和时间有正向影响。这些发现对产品/项目经理理解是什么促使用户参与社交媒体以及如何设计社交媒体以进一步提高用户参与度具有实用意义。
