This study looks at the impact of national diversity on task and relationship conflict in the context of global virtual teams (GVTs). We investigate the interaction effects of both English skills and openness to linguistic diversity on these relationships. We administered a questionnaire to 283 GVTs working on a collaborative experiential learning project to develop an international business plan. Our results show that, for teams exhibiting high levels of openness to linguistic diversity and high levels of English skills, increased levels of national diversity on the team are associated with lower levels of task and relationship conflict. The relationship is reversed, however, in teams where openness to linguistic diversity and team English skills are low. These findings shed light on the relationship between national diversity and conflict by suggesting that both English skills and team attitudes toward language diversity are important in reducing conflict. Moreover, openness to linguistic diversity may be more important in reducing conflict than the level of team members’ language proficiency. 
本研究着眼于全球虚拟团队(gvt)背景下国家多样性对任务和关系冲突的影响。我们研究了英语技能和对语言多样性的开放程度对这些关系的相互作用。我们对283名参与合作体验式学习项目的gvt进行了问卷调查,以制定一项国际商业计划。我们的研究结果表明,对于表现出对语言多样性高度开放和英语技能水平较高的团队来说,团队中国家多样性水平的提高与任务和关系冲突水平的降低有关。然而,在对语言多样性的开放程度和团队英语技能较低的团队中,这种关系是相反的。这些发现揭示了民族多样性和冲突之间的关系,表明英语技能和团队对语言多样性的态度在减少冲突方面都很重要。此外,在减少冲突方面,对语言多样性持开放态度可能比团队成员的语言熟练程度更重要。

Volatility Behaviour of Bitcoin as a Digital Asset 比特币作为数字资产的波动行为
Q2 Social Sciences Pub Date : 2022-06-10 DOI: 10.18080/jtde.v10n2.510
T. Gopane
The objective of this study is to use the South African financial markets (Johannesburg Stock Exchange or JSE and USD/ZAR) as a case study to understand the volatility spillover dynamics of Bitcoin as a digital asset. Methodologically, the study applies the exponential generalized autoregressive conditional heteroskedastic (EGARCH) model, followed by a robustness check by applying the time-varying conditional correlation multivariate GARCH (VCC-MGARCH) model. The study utilizes the data set for the period 2011 to 2019, a period before the COVID‑19 pandemic. The research outcome revealed three interesting observations. First, Bitcoin and the South African stock market are independent of each other. Second, there is a bidirectional shock transmission between Bitcoin and USD/ZAR in the mean returns only, but not variance. Lastly, results confirm the existence of a bidirectional volatility spillover in both the mean and variance between the JSE stock market and the USD/ZAR market. The study outcome should enlighten investors who may want to consider Bitcoin as a diversifier in their investment and portfolio strategies.
本研究的目的是使用南非金融市场(约翰内斯堡证券交易所或JSE和USD/ZAR)作为案例研究,以了解比特币作为数字资产的波动性溢出动态。在方法上,本研究采用指数广义自回归条件异方差(EGARCH)模型,然后采用时变条件相关多元GARCH (vc - mgarch)模型进行稳健性检验。该研究使用了2011年至2019年期间的数据集,这是COVID - 19大流行之前的一段时间。研究结果揭示了三个有趣的观察结果。首先,比特币和南非股市是相互独立的。其次,比特币与USD/ZAR之间存在双向冲击传导,仅在均值收益上存在,而方差不存在。最后,结果证实了JSE股票市场和USD/ZAR市场之间的均值和方差都存在双向波动溢出。研究结果应该启发那些可能希望将比特币视为投资和投资组合策略多元化的投资者。

Social Media Data Analytics for Marketing Strategies 营销策略的社交媒体数据分析
Q2 Social Sciences Pub Date : 2022-06-10 DOI: 10.18080/jtde.v10n2.523
Teissir Benslama, Rim Jallouli
The analysis of social media data to extract new insights has attracted much attention, especially in the field of Marketing. Few researchers, however, have studied both the concepts of Social Media Data Analytics (SMDA) and Marketing Strategies. Previous publications have only focused on a particular technique or a well-defined Marketing Strategy in a specific context. To address this gap, this paper aims to explore how Social Media Data Analytics can guide and affect Marketing Strategies, and provide an overview of the range of Social Media Data Analytics techniques related to Marketing Strategies. We conducted a systematic review of 120 papers published between 2015 and 2021 on SMDA in Marketing. The findings are presented in terms of the main social media platforms, publication date, journal quality, social media data types, analytical techniques, fields of application, firm size, and related Marketing Strategies. The SMDA techniques are classified into six categories: Sentiment Analysis, Artificial Intelligence, Data Mining, Statistics, Coding and Modelling, and Simulation. A set of detailed Marketing Strategies guided by SMDA are also presented, as well as an integrative framework mapping how SMDA creates value. The results highlight several SMDA techniques that still lack exploration and outline their relevance.
通过分析社交媒体数据来获取新的见解已经引起了人们的广泛关注,尤其是在市场营销领域。然而,很少有研究人员同时研究了社交媒体数据分析(SMDA)和营销策略的概念。以前的出版物只关注特定环境下的特定技术或定义良好的营销策略。为了解决这一差距,本文旨在探讨社交媒体数据分析如何指导和影响营销策略,并提供与营销策略相关的社交媒体数据分析技术范围的概述。我们对2015年至2021年间发表的120篇SMDA in Marketing论文进行了系统回顾。研究结果包括主要社交媒体平台、出版日期、期刊质量、社交媒体数据类型、分析技术、应用领域、公司规模和相关营销策略。SMDA技术分为六大类:情感分析、人工智能、数据挖掘、统计、编码和建模以及仿真。一套详细的营销策略由SMDA指导,以及一个综合框架映射SMDA如何创造价值。结果强调了几个仍然缺乏探索的SMDA技术,并概述了它们的相关性。

Measuring E-Browsing Behaviour and Testing its Impact on Online Immersion 测量电子浏览行为并测试其对在线沉浸的影响
Q2 Social Sciences Pub Date : 2022-06-10 DOI: 10.18080/jtde.v10n2.546
Salma Ayari, Imène Ben Yahia, M. Debabi
In an online environment, enriched by different types of cues that may distract a consumer, investigating and operationalizing, e-browsing behaviour becomes a must to understand consumer behaviour online. Nevertheless, existing research on the online environment has only used and adapted scales measuring offline browsing. In fact, the existing literature fails to offer a scale measuring browsing specifically in the online context. Consequently, this study fills this gap by developing a scale measuring e-browsing following the Churchill paradigm enriched with the recommendations of Rossiter. For this purpose, a number of methodological instruments are used: two focus groups (the first with 4 experts and the second with 18 consumers) and three surveys (140 students for the first survey, 350 and 200 Internet users, respectively, for the second and third survey). Results put forth a unidimensional scale with 7 items, which seems to exhibit evidence of reliability and validity. The predictive validity was checked by testing the impact of e-browsing on online immersion. The proposed scale measure may help academicians perform better and more reliable studies on consumer behaviour online. It may help managers better understand the traffic on their websites and segment visitors to tailor better conversion strategies.
在网络环境中,不同类型的线索可能会分散消费者的注意力,调查和操作,电子浏览行为成为了解消费者在线行为的必要条件。然而,现有的在线环境研究只使用和调整了测量离线浏览的量表。事实上,现有的文献并没有提供一个衡量在线浏览行为的尺度。因此,本研究通过开发一个测量电子浏览的量表来填补这一空白,该量表遵循丘吉尔范式,并丰富了Rossiter的建议。为此目的,使用了一些方法工具:两个焦点小组(第一个有4名专家,第二个有18名消费者)和三个调查(第一次调查140名学生,第二次和第三次调查分别有350名和200名互联网用户)。结果得出一个包含7个条目的单维量表,具有一定的信度和效度。通过测试电子浏览对网络沉浸感的影响来检验预测效度。拟议的量表可能会帮助学者们对在线消费者行为进行更好、更可靠的研究。它可以帮助管理者更好地了解他们网站上的流量,并对访问者进行细分,从而制定更好的转化策略。

Technology-enabled Personalization for Mobile Banking Services 移动银行服务的技术支持个性化
Q2 Social Sciences Pub Date : 2022-06-10 DOI: 10.18080/jtde.v10n2.545
Moetez Khemiri, Rim Jallouli
New technologies are giving very interesting potential to the personalization of products and services, in particular of mobile services. The study of the literature shows that technology-based personalization is an important factor in the adoption of mobile services. However, previous researchers are not unanimous as to the nature of this role: some studies confirm the moderating or mediating effect of personalization on the relationship between the adoption factors stated in the Unified Technology Acceptance and Utilization Theory (UTAUT) and the intention to adopt technology-based services. Other researchers consider that personalization rather exerts a causal relationship on the adoption of technology-based services. This paper undertakes a literature review with the aim of clarifying the impact of new technologies, such as artificial intelligence, Big Data, Internet of Things and Block Chain, on the personalization of mobile banking services. Moreover, this study presents a synthesis of previous research examining the role of personalization in relation to the factors affecting adoption and the intention to adopt mobile banking. Finally, this research proposes a conceptual model that can serve as a basis for future empirical research in the context of mobile services. Results and discussion could guide future empirical research in this area.
新技术为产品和服务的个性化提供了非常有趣的潜力,尤其是移动服务。文献研究表明,基于技术的个性化是移动服务采用的重要因素。然而,以往的研究人员对这一作用的性质并不一致:一些研究证实了个性化对统一技术接受和利用理论(UTAUT)中所述的采用因素与采用基于技术的服务的意愿之间的关系的调节或中介作用。其他研究人员认为,个性化对采用基于技术的服务产生了因果关系。本文进行文献综述,旨在阐明人工智能、大数据、物联网、区块链等新技术对手机银行个性化服务的影响。此外,本研究综合了以往的研究,考察了个性化在影响采用和采用移动银行意愿的因素中的作用。最后,本研究提出了一个概念模型,可以作为未来移动服务背景下实证研究的基础。研究结果和讨论可以指导该领域未来的实证研究。

Secure Attendance System using Raspberry Pi Face Recognition 使用树莓派人脸识别的安全考勤系统
Q2 Social Sciences Pub Date : 2022-06-10 DOI: 10.18080/jtde.v10n2.530
Rhouma Bin Hamed, Tarek Fatnassi
This study aims to develop a machine-learning-based attendance management system using face recognition and Raspberry Pi. The proposed system is composed of two main subsystems. The first is a Raspberry Pi, to be installed in each class, and the second is a web application fed by data from the Raspberry Pi. To take attendance, an instructor commands a Raspberry Pi camera through a web-based subsystem. Then, the camera takes a picture of the whole class and detects faces using trained Haar Cascades. It sends back a file with the class picture and Cartesian coordinates of the detected faces. The web application parses the file, looking for the coordinates of faces. For each Region of Interest, it uses the Support Vector Machine algorithm to recognize faces based on their HOG (Histogram of Oriented Gradients) features. The recognizer uses a pre-built dataset of that particular class containing the students’ personal photos, names and ID numbers. Features of each face were extracted using HOG and trained to construct the model over a given class of students. Once every detected face is recognized, the application generates a report for the instructor showing the list of students’ names and attendance status.
本研究旨在利用人脸识别和树莓派开发一个基于机器学习的考勤管理系统。该系统由两个主要子系统组成。第一个是树莓派,安装在每个班级中,第二个是一个web应用程序,由树莓派提供数据。要出勤,教师通过基于web的子系统命令树莓派相机。然后,相机拍摄整个班级的照片,并使用训练有素的哈尔瀑布检测人脸。它返回一个文件,其中包含类图片和检测到的人脸的笛卡尔坐标。web应用程序解析文件,查找面坐标。对于每个感兴趣的区域,它使用支持向量机算法基于HOG (Histogram of Oriented Gradients)特征来识别人脸。识别器使用预先构建的特定班级的数据集,其中包含学生的个人照片、姓名和身份证号码。使用HOG提取每张脸的特征,并对其进行训练,以构建给定班级的学生模型。一旦识别出每个检测到的人脸,应用程序就会为教师生成一个报告,显示学生姓名和出勤状态的列表。

Several years after introducing the mobile payment service to the Lebanese market, it is clear that the new payment method has failed to take off, which brings up questions about the reasons behind these unmet expectations. The current paper uses the Technology-Organization-Environment framework to explore the factors with respect to its three pillars that could have prevented the diffusion of mobile payment into the market. Using a qualitative approach of multiple case studies, the findings suggest that the reasons for the low diffusion of mobile banking lies as much in the incompatible nor open technology as in the highly competitive organizational structure of the banking industry and, finally, the merchants’ and consumers’ unwillingness to adopt it.
在黎巴嫩市场推出移动支付服务几年后,很明显,这种新的支付方式并没有起飞,这引发了人们对这些未达到预期的原因的疑问。本文使用技术-组织-环境框架来探讨可能阻碍移动支付向市场扩散的三大支柱因素。采用多案例研究的定性方法,研究结果表明,手机银行扩散低的原因既在于技术不兼容,也在于银行业高度竞争的组织结构,最后,商家和消费者不愿意采用它。

Effective Optimization of Billboard Ads Based on CDR Data Leverage 基于CDR数据杠杆的广告牌广告有效优化
Q2 Social Sciences Pub Date : 2022-06-10 DOI: 10.18080/jtde.v10n2.527
Imed Eddine Semassel, Sadok Ben Yahia
Call Detail Records (CDRs) provide metadata about phone calls and text message usage. Many studies have shown these CDR data to provide gainful information on people's mobility patterns and relationships with fine-grained aspects, both temporal and spatial elements. This information allows tracking population levels in each country region, individual movements, seasonal locations, population changes, and migration. This paper introduces a method for analyzing and exploiting CDR data to recommend billboard ads. We usher by clustering the locations based on the recorded activities' pattern regarding users' mobility. The key idea is to rate sites by performing a thorough cluster analysis over the achieved data, having no prior ground-truth information, to assess and optimize the ads' placements and timing for more efficiency at the billboards.
话单(Call Detail Records)提供了有关通话和短信使用情况的元数据。许多研究表明,这些CDR数据提供了有关人们流动模式和与时间和空间元素的细粒度方面的关系的有益信息。这些信息可以跟踪每个国家区域的人口水平、个人流动、季节性地点、人口变化和迁移。本文介绍了一种分析和利用CDR数据来推荐广告牌广告的方法。我们根据用户的移动性,根据记录的活动模式对位置进行聚类。其关键思想是通过对已获得的数据进行彻底的聚类分析来对网站进行评级,而不需要事先的基本事实信息,从而评估和优化广告的放置位置和时间,以提高广告牌的效率。

How to Manage Companies in the Digital Age 如何在数字时代管理公司
Q2 Social Sciences Pub Date : 2022-06-10 DOI: 10.18080/jtde.v10n2.498
O. Stoianova, T. Lezina, V. Ivanova
The period of high expectations of digital transformation benefits is followed by a period of discussion on strategies and methods for managing digital changes. Not only the rapid development of technology, but also the turbulence of the external environment contribute to the view that traditional approaches to strategic management of the company are irrelevant. Understanding the need to modify classic strategic management methods actualises the task of developing new methodological fundamentals for strategic management. The initial stage of solving this problem is the analysis of the current state of research in this area. This study analyses the Russian research community viewpoints on the prospects of companies' strategic management regarding the digital economy status quo and trends in Russia. This paper answers the following research questions. What impact does the digital economy environment of Russian companies have on their management systems and what are the prerequisites for changing approaches and mechanisms of strategic management? How do the basic strategic management approaches differ for companies with different experiences, capabilities, and expectations of digital transformation? The key managerial prospects of the study concern the benefits of various strategic management approaches for companies with different backgrounds, capabilities, and expectations of digital transformation.

Measuring and managing customer experience is increasingly becoming a priority in the experience-laden hospitality context. With the growing desire of consumers for living more authentic experiences, the collaborative consumption (CC) model has gained significant popularity in this industry. However, to date, the underlying structure of customer experience in a hospitality CC context has not been uncovered and a generalizable quantitative measure is yet to be developed. To fill this gap, this research aims to develop and validate a scale for measuring customer experience in a hospitality CC context. Based on a sample collected from Airbnb customers, results yield a 17-item five-dimensional scale (Platform brand experience, Accommodation sensory experience, Social experience with the host, Platform responsive capacity, and Quality of interaction with the host). This work demonstrates that providing an excellent customer experience in a CC context stems from a customer-centred approach from all the involved parties. Theoretical and managerial implications are also presented, along with relevant research avenues.
衡量和管理客户体验正日益成为充满体验的酒店业的首要任务。随着消费者对生活更真实体验的渴望日益增长,协作消费(CC)模式在这个行业得到了极大的普及。然而,迄今为止,酒店CC背景下的客户体验的基本结构尚未被揭示,一种可推广的定量测量方法尚未开发。为了填补这一空白,本研究旨在开发和验证一个衡量酒店CC背景下客户体验的量表。基于从Airbnb客户中收集的样本,结果产生了17个项目的五维量表(平台品牌体验,住宿感官体验,与房东的社交体验,平台响应能力和与房东的互动质量)。这项工作表明,在CC环境中提供优秀的客户体验源于所有相关方以客户为中心的方法。理论和管理意义也提出,以及相关的研究途径。
