User-centric avatar design: A cognitive walkthrough approach for metaverse in virtual education 以用户为中心的头像设计：虚拟教育中的元宇宙认知演练方法

Data Science and Management

Pub Date : 2024-05-19 DOI: 10.1016/j.dsm.2024.05.001

Metaverse, once a concept confined to science fiction, has emerged as a transformative reality during the digital era. As this immersive virtual world gains prominence, the role of avatars and the digital representations of users in shaping educational experiences within a metaverse becomes increasingly crucial. This study examined the design of avatars and their effectiveness in virtual education. Using the cognitive walkthrough (CW) method, a well-established user-centric assessment approach, this study examined how users engage in avatar design in virtual educational settings, highlighting their cognitive processes. Through the CW approach, this study identified usability issues and learning challenges, providing valuable insights into the user experience. The investigation focuses on the VRoid platform for avatar design, selected for its user-friendly interface and robust customization features. Participants (n = 12; six men and six women) from diverse educational backgrounds were carefully selected to offer a comprehensive range of perspectives. They performed avatar design tasks that closely mirrored the learning environment of the metaverse, followed by in-depth post-exercise interviews. The findings of this study highlight the essential role of avatar design in enhancing user engagement and improving the learning outcomes of virtual education. Furthermore, we provide practical recommendations for educators and designers to effectively leverage avatar innovation. In a continuously evolving era of metaverse, this research contributes significantly to the ongoing discourse on user-centered design in educational settings, thereby influencing the future trajectory of virtual education.

元宇宙（Metaverse）曾经是科幻小说中的一个概念，但在数字时代已成为一种变革性的现实。随着这种身临其境的虚拟世界日益突出，化身和用户的数字代表在塑造元宇宙中的教育体验方面的作用变得越来越重要。本研究考察了虚拟化身的设计及其在虚拟教育中的有效性。认知演练（CW）是一种行之有效的以用户为中心的评估方法，本研究采用认知演练（CW）方法，考察了用户如何在虚拟教育环境中参与化身设计，突出了他们的认知过程。通过 CW 方法，本研究发现了可用性问题和学习挑战，为用户体验提供了宝贵的见解。调查的重点是用于化身设计的 VRoid 平台，该平台因其友好的用户界面和强大的定制功能而被选中。我们精心挑选了来自不同教育背景的参与者（n = 12；六男六女），以提供全面的视角。他们完成了与元宇宙学习环境密切相关的化身设计任务，随后进行了深入的练习后访谈。本研究的结果强调了虚拟化身设计在提高用户参与度和改善虚拟教育学习效果方面的重要作用。此外，我们还为教育者和设计者提供了切实可行的建议，以有效利用虚拟化身创新。在不断发展的元宇宙时代，本研究为当前教育环境中以用户为中心的设计讨论做出了重要贡献，从而影响了虚拟教育的未来发展轨迹。

Trust and involvement of Cameroonian software developers in open-source projects 喀麦隆软件开发人员对开源项目的信任和参与情况

Data Science and Management

Pub Date : 2024-05-06 DOI: 10.1016/j.dsm.2024.04.005

Although recent studies have examined collaboration within open-source software projects, the focus has primarily been on their motivations and governance. This study explores the complex dynamics of trust and involvement among Cameroonian software developers in open-source projects. In the context of a rapidly evolving software development landscape, these projects have emerged as a transformative force, redefining global collaboration standards. The qualitative methodological approach involved a survey of 22 participants in open-source software projects, including Cameroonian software developers, project governance actors, and open-source community members. Analyses revealed that the trust given to African software developers, including their effective integration into projects and consideration of their specificities and contributions, has a positive impact on their involvement in and ability to appropriate information technologies. By exploring the interaction between cultural, social, and technological factors, this study enhances our understanding of trust mechanisms within open-source communities, especially those involving remote developers.

尽管最近的研究对开源软件项目中的合作进行了研究，但重点主要放在其动机和管理上。本研究探讨了喀麦隆软件开发人员对开源项目的信任和参与的复杂动态。在软件开发领域迅速发展的背景下，这些项目已成为一股变革力量，重新定义了全球协作标准。采用定性方法对开源软件项目的 22 名参与者进行了调查，其中包括喀麦隆软件开发人员、项目管理人员和开源社区成员。分析表明，对非洲软件开发人员的信任，包括将他们有效地纳入项目并考虑他们的特殊性和贡献，对他们参与和利用信息技术的能力产生了积极影响。通过探索文化、社会和技术因素之间的相互作用，本研究加深了我们对开源社区内信任机制的理解，尤其是那些涉及远程开发人员的社区。

Will China’s carbon-trading policy foster coordinated innovation in green technologies? 中国的碳交易政策能否促进绿色技术的协调创新？

Data Science and Management

Pub Date : 2024-05-04 DOI: 10.1016/j.dsm.2024.04.004

Accelerating green innovation is crucial for achieving high-quality development in China. Despite this importance, empirical evidence on the harmonization techniques in the context of carbon-trading policies has been remarkably thin. To address this gap, we employed the difference-in-difference (DID) and spatial difference-in-difference (S-DID) models using panel data from 2007 to 2017 for 30 Chinese provinces. Our findings reveal that the carbon-trading policy contributes significantly to the coordinated advancement of green technologies across Chinese provinces and exhibits a local siphoning effect. Specifically, the pilot areas of the policy have attracted talent from neighboring regions, which has fostered local cooperation and promoted coordinated innovation in green technologies within the region.

加快绿色创新对中国实现高质量发展至关重要。尽管如此重要，但有关碳交易政策背景下协调技术的实证证据却少得可怜。为了弥补这一不足，我们利用 2007 年至 2017 年中国 30 个省份的面板数据，采用了差分（DID）和空间差分（S-DID）模型。我们的研究结果表明，碳交易政策极大地促进了中国各省绿色技术的协调发展，并表现出地方虹吸效应。具体而言，政策试点地区吸引了周边地区的人才，促进了地方合作，推动了区域内绿色技术的协调创新。

The research community and digital sector are currently engaged in the development of diverse services within the metaverse ecosystems. Conversely, as concerns about safeguarding personal privacy mount, individuals anticipate exercising greater authority over the way third parties make use of sensitive information, such as medical data. This study aims to develop tools that can facilitate the provision of healthcare services within the metaverse ecosystem in a safe and trustworthy way. This project proposes a trust framework for digital healthcare applications to run in a metaverse environment. The framework is based on the use of self-sovereign identity (SSI) and has been tested on the design principles outlined for the SSI-based architecture. This study outlines two use-case scenarios that can serve as foundations for implementing a trust framework.

目前，研究界和数字部门正在开发元宇宙生态系统中的各种服务。与此相反，随着人们对个人隐私保护的日益关注，个人希望对第三方使用医疗数据等敏感信息的方式行使更大的权力。本研究旨在开发工具，以安全、可信的方式促进在元宇宙生态系统中提供医疗保健服务。该项目为在元宇宙环境中运行的数字医疗保健应用程序提出了一个信任框架。该框架以使用自我主权身份（SSI）为基础，并根据基于 SSI 架构的设计原则进行了测试。本研究概述了可作为实施信任框架基础的两个用例场景。

Comparative analysis of manual and programmed annotations for crowd assessment and classification using artificial intelligence 利用人工智能进行人群评估和分类的人工和注释比较分析

Data Science and Management

Pub Date : 2024-04-05 DOI: 10.1016/j.dsm.2024.04.001

Funding agencies play a pivotal role in bolstering research endeavors by allocating financial resources for data collection and analysis. However, the lack of detailed information regarding the methods employed for data gathering and analysis can obstruct the replication and utilization of the results, ultimately affecting the study’s transparency and integrity. The task of manually annotating extensive datasets demands considerable labor and financial investment, especially when it entails engaging specialized individuals. In our crowd counting study, we employed the web-based annotation tool SuperAnnotate to streamline the human annotation process for a dataset comprising 3,000 images. By integrating automated annotation tools, we realized substantial time efficiencies, as demonstrated by the remarkable achievement of 858,958 annotations. This underscores the significant contribution of such technologies to the efficiency of the annotation process.

资助机构通过为数据收集和分析分配财政资源，在支持研究工作方面发挥着举足轻重的作用。然而，如果缺乏有关数据收集和分析方法的详细信息，就会阻碍结果的复制和利用，最终影响研究的透明度和完整性。对大量数据集进行人工标注需要投入大量的人力和财力，尤其是在需要聘请专业人员的情况下。在我们的人群计数研究中，我们采用了基于网络的注释工具 SuperAnnotate 来简化由 3,000 张图像组成的数据集的人工注释过程。通过整合自动注释工具，我们大大提高了时间效率，858,958 次注释的显著成果就证明了这一点。这凸显了此类技术对提高注释过程效率的重大贡献。
