Although cloud computing offers many benefits, such as flexibility, scalability, and profitability, some small and medium enterprises (SMEs) are still unable to fully utilize cloud resources, such as memory, computing power, storage, and network bandwidth. This reduces their productivity and increases their expenses. Therefore, the central objective of this paper was to examine the key challenges related to the allocation of cloud computing resources in small and medium enterprises. The method used for this study is based upon qualitative research using 12 interviews with 12 owners, managers, and experts in cloud computing in four countries: the United States of America, the United Kingdom, India, and Pakistan. Our results, based on our empirical data, show 11 key barriers to resource allocation in cloud computing that are classified based on the technology, organization, and environment (TOE) framework. Theoretically, this research contributes to the body of knowledge concerning cloud computing technology and offers valuable understanding of the cloud computing resource allocation approaches employed by small and medium enterprises (SMEs). In practice, this research is useful to aid SMEs in implementing successful and sustainable strategies for allocating cloud computing resources.
尽管云计算具有灵活性、可扩展性和盈利能力等诸多优势,但一些中小企业(SMEs)仍无法充分利用内存、计算能力、存储和网络带宽等云资源。这降低了他们的生产力,增加了他们的开支。因此,本文的中心目标是研究与中小企业云计算资源分配相关的主要挑战。本研究采用的方法是基于定性研究,在美国、英国、印度和巴基斯坦四个国家对 12 位云计算企业主、经理和专家进行了 12 次访谈。根据我们的经验数据,我们的研究结果显示了云计算资源分配的 11 个关键障碍,这些障碍根据技术、组织和环境(TOE)框架进行了分类。从理论上讲,本研究为云计算技术相关知识体系做出了贡献,并为了解中小企业(SMEs)采用的云计算资源分配方法提供了宝贵的资料。在实践中,本研究有助于帮助中小型企业成功实施可持续的云计算资源分配策略。

This paper addresses the research gap in the realm of data-driven transformation by leveraging the Resource-Based View (RBV) theory and the dynamic capabilities concept to the contours of a data-driven enterprise. It confronts the limitations of conventional digital and data transformation programs, which often prioritize technological enhancements over crucial organizational and cultural shifts. Proposing a more holistic perspective, the Data-Driven Enterprise Architecture Framework (DDA) is introduced, emphasizing the domain decomposition and productization of an architecture, distributed ownership, and federated governance, while ensuring the continuous harmonization of data, application, and business architecture. A case study featuring a leading pharmaceutical company illustrates the practical implementation of the DDA framework as a pillar of their Digital Transformation Strategy. By integrating scalable and distributed data architecture into the overarching Enterprise Architecture landscape, the company has initiated their data-driven transformation journey, showcased through their initial and very early results. This research not only offers valuable insights for pharmaceutical organizations navigating the complexities of data-driven transformations, but also addresses a research gap in the field.

Generative Artificial Intelligence (GenAI) image tools hold the promise of revolutionizing a designer’s creative process. The increasing supply of this type of tool leads us to consider whether they suit future design professionals. This study aims to unveil if three GenAI image tools—Midjourney 5.2, DreamStudio beta, and Adobe Firefly 2—meet future designers’ expectations. Do these tools have good Usability, show sufficient User Experience (UX), induce positive emotions, and provide satisfactory results? A literature review was performed, and a quantitative empirical study based on a multidimensional analysis was executed to answer the research questions. Sixty users used the GenAI image tools and then responded to a holistic evaluation framework. The results showed that while the GenAI image tools received favorable ratings for Usability, they fell short in achieving high scores, indicating room for improvement. None of the platforms received a positive evaluation in all UX scales, highlighting areas for enhancement. The benchmark comparison revealed that all platforms, except for Adobe Firefly’s Efficiency scale, require enhancements in pragmatic and hedonic qualities. Despite inducing neutral to above-average positive emotions and minimal negative emotions, the overall satisfaction was moderate, with Midjourney aligning more closely with user expectations. This study emphasizes the need for significant improvements in Usability, positive emotional resonance, and result satisfaction, even more so in UX, so that GenAI image tools can meet future designers’ expectations.
生成式人工智能(GenAI)图像工具有望彻底改变设计师的创作过程。这类工具的供应量不断增加,促使我们思考它们是否适合未来的设计专业人士。本研究旨在揭示三款 GenAI 图像工具--Midjourney 5.2、DreamStudio beta 和 Adobe Firefly 2--是否符合未来设计师的期望。这些工具是否具有良好的可用性、足够的用户体验(UX)、诱发积极情绪并提供令人满意的结果?为了回答这些研究问题,我们进行了文献综述,并基于多维分析开展了一项定量实证研究。60 名用户使用了 GenAI 图像工具,然后对整体评估框架做出了回应。结果表明,虽然 GenAI 图像工具在可用性方面获得了好评,但却未能获得高分,这表明它们还有改进的余地。没有一个平台在所有用户体验方面都获得了积极的评价,这凸显了需要改进的地方。基准比较显示,除了 Adobe Firefly 的效率量表外,所有平台都需要在实用性和享乐性方面进行改进。尽管 "Midjourney "诱发了中性到高于平均水平的积极情绪和极少的消极情绪,但总体满意度一般,更符合用户的期望。本研究强调了在可用性、积极情感共鸣和结果满意度方面进行重大改进的必要性,在用户体验方面更是如此,从而使 GenAI 图像工具能够满足未来设计师的期望。

Quality Control Methods Using Quality Characteristics in Development and Operations 在开发和运营中使用质量特性的质量控制方法
Pub Date : 2024-03-01 DOI: 10.3390/digital4010012
Daiju Kato, H. Ishikawa
Since the Software Quality Model was defined as an international standard, many quality assurance teams have used this quality model in a waterfall model for software development and quality control. As more software is delivered as a cloud service, various methodologies have been created with an awareness of the link between development productivity and operations, enabling faster development. However, most development methods are development-oriented with awareness of development progress, and there has been little consideration of methods that achieve quality orientation for continuous quality improvement and monitoring. Therefore, we developed a method to visualize the progress of software quality during development by defining quality goals in the project charter using the quality model defined in international standards, classifying each test by quality characteristics, and clarifying the quality ensured by each test. This was achieved by classifying each test by quality characteristics and clarifying the quality ensured by each test. To use quality characteristics as KPIs, it is necessary to manage test results for each test type and compare them with past build results. This paper explains how to visualize the quality to be assured and the benefits of using quality characteristics as KPIs and proposes a method to achieve rapid and high-quality product development.
自从软件质量模型被定义为国际标准以来,许多质量保证团队都在软件开发和质量控制的瀑布模型中使用这一质量模型。随着越来越多的软件以云服务的形式交付,人们意识到开发效率与运营之间的联系,从而创建了各种方法,以加快开发速度。然而,大多数开发方法都是以开发为导向,以了解开发进度为目的,而很少考虑采用以质量为导向的方法来实现持续的质量改进和监控。因此,我们开发了一种方法,通过使用国际标准中定义的质量模型在项目章程中定义质量目标,按质量特性对每个测试进行分类,并明确每个测试所确保的质量,从而在开发过程中可视化软件质量的进展情况。具体做法是根据质量特性对每个测试进行分类,并明确每个测试所确保的质量。要将质量特性用作关键绩效指标,就必须管理每种测试类型的测试结果,并将其与过去的构建结果进行比较。本文介绍了如何将需要确保的质量可视化,以及将质量特性作为关键绩效指标的好处,并提出了一种实现快速、高质量产品开发的方法。

This study aspires to contribute some initial results to the growing area of research regarding technology potential in the field of early foreign language literacy. An experiment was conducted to examine very young learners’ alphabet and vocabulary learning and retention in an early foreign language (FL) learning context when implementing augmented reality (AR) applications, while very young learners’ motivation was also assessed. A pilot intervention was implemented in a state school in northern Greece. The participants (n = 26) were primary school first-graders (5.5–6 years old) and were assigned into two groups, experimental (13) and control (13). To examine the effects of the intervention, this current study employed two instruments: (a) a pre-test–post-test model to assess young learners’ alphabet and vocabulary learning during three phases and (b) a questionnaire to assess their motivation during the learning process. The findings of this study reveal that both groups displayed significant improvements in FL alphabet and vocabulary learning; however, there are statistical differences in favor of the experimental group regarding long-term alphabet and vocabulary learning and retention. Furthermore, qualitative results regarding children’s perceptions of the technology used indicate that AR was highly appealing and motivating to participating students.
本研究旨在为早期外语扫盲领域日益增长的技术潜力研究贡献一些初步成果。研究人员进行了一项实验,以考察在早期外语(FL)学习环境中使用增强现实(AR)应用程序时,年幼学习者的字母和词汇学习及保持情况,同时还对年幼学习者的学习动机进行了评估。希腊北部的一所公立学校实施了一项试点干预措施。参与者(n = 26)为小学一年级学生(5.5-6 岁),被分为两组,实验组(13 人)和对照组(13 人)。为了考察干预的效果,本研究采用了两种工具:(a) 采用前测-后测模式,评估小学生在三个阶段的字母和词汇学习情况;(b) 采用问卷调查,评估小学生在学习过程中的学习动机。研究结果表明,两组学生在 FL 字母和词汇学习方面均有显著提高;但在字母和词汇的长期学习和保持方面,实验组学生的成绩在统计学上存在差异。此外,有关儿童对所使用技术的看法的定性结果表明,增强现实技术对参与研究的学生具有很强的吸引力和激励作用。

This study aspires to contribute some initial results to the growing area of research regarding technology potential in the field of early foreign language literacy. An experiment was conducted to examine very young learners’ alphabet and vocabulary learning and retention in an early foreign language (FL) learning context when implementing augmented reality (AR) applications, while very young learners’ motivation was also assessed. A pilot intervention was implemented in a state school in northern Greece. The participants (n = 26) were primary school first-graders (5.5–6 years old) and were assigned into two groups, experimental (13) and control (13). To examine the effects of the intervention, this current study employed two instruments: (a) a pre-test–post-test model to assess young learners’ alphabet and vocabulary learning during three phases and (b) a questionnaire to assess their motivation during the learning process. The findings of this study reveal that both groups displayed significant improvements in FL alphabet and vocabulary learning; however, there are statistical differences in favor of the experimental group regarding long-term alphabet and vocabulary learning and retention. Furthermore, qualitative results regarding children’s perceptions of the technology used indicate that AR was highly appealing and motivating to participating students.
本研究旨在为早期外语扫盲领域日益增长的技术潜力研究贡献一些初步成果。研究人员进行了一项实验,以考察在早期外语(FL)学习环境中使用增强现实(AR)应用程序时,年幼学习者的字母和词汇学习及保持情况,同时还对年幼学习者的学习动机进行了评估。希腊北部的一所公立学校实施了一项试点干预措施。参与者(n = 26)为小学一年级学生(5.5-6 岁),被分为两组,实验组(13 人)和对照组(13 人)。为了考察干预的效果,本研究采用了两种工具:(a) 采用前测-后测模式,评估小学生在三个阶段的字母和词汇学习情况;(b) 采用问卷调查,评估小学生在学习过程中的学习动机。研究结果表明,两组学生在 FL 字母和词汇学习方面均有显著提高;但在字母和词汇的长期学习和保持方面,实验组学生的成绩在统计学上存在差异。此外,有关儿童对所使用技术的看法的定性结果表明,增强现实技术对参与研究的学生具有很强的吸引力和激励作用。

The COVID-19 pandemic led to widespread restrictions globally, prompting governments to implement measures for containment. Vaccines, while aiding in reducing virus transmission, have also introduced the challenge of identifying vaccinated individuals for the purpose of easing restrictions. The European Union (EU) addressed this through the “digital COVID-19 certification” system, allowing citizens to travel within the EU based on their vaccination, recovery, or negative test status. However, the system’s digital format poses challenges for those who are not digitally proficient, such as seniors and those with low educational or socioeconomic status. This study aims to propose enhancements to the current system, considering the mobility needs of all citizens. The methodology involves reviewing literature on digital literacy, the digital divide, and information systems related to vaccination and certification. The paper presents straightforward recommendations to make the COVID-19 certificate more accessible to digitally excluded individuals. These proposals may serve as a valuable starting point for healthcare executives to evaluate and adapt the certification scheme to be inclusive of a broader range of stakeholders.
COVID-19 大流行导致全球范围内的广泛限制,促使各国政府采取遏制措施。疫苗在帮助减少病毒传播的同时,也带来了如何识别已接种疫苗的个人以放宽限制的难题。欧盟(EU)通过 "数字 COVID-19 认证 "系统解决了这一问题,该系统允许公民根据其疫苗接种、康复或阴性检测状况在欧盟境内旅行。然而,该系统的数字格式给那些不精通数字技术的人带来了挑战,例如老年人和教育或社会经济地位较低的人。本研究旨在考虑到所有公民的移动需求,对当前系统提出改进建议。研究方法包括回顾有关数字素养、数字鸿沟以及与疫苗接种和认证相关的信息系统的文献。本文提出了一些简单明了的建议,使 COVID-19 证书更便于被数字鸿沟排除在外的个人使用。这些建议可作为医疗保健管理人员评估和调整认证计划的宝贵起点,使其能够包容更广泛的利益相关者。
