The technology acceptance model (TAM) has long-term implications for management studies. However, the evolution of the literature on technology acceptance ideas received very little attention in the bibliographic review. Few research reviews provided a systematic overview of the development and progress of the TAM literature based on the entire citation network, while many research reviews focused on re-examining the links between TAM components through meta-analysis. This study investigates: a) how TAM research has evolved and expanded over the last 30 years; b) the main areas in which the TAM model has been used; and c) key contributors to TAM research and their collaborations. This bibliometric analysis was carried out based on 8207 papers published in the Scopus database between 1990 and 2020 to assess the feasibility of the model and its applicability. The findings revealed that early TAM research was conducted both by Eastern and Western scholars and that it has since continued to evolve and be shared widely. Nonetheless, most TAM publications have focused on the same narrow domains of computer science, social science, business, management, and accounting and the trendiest topics were usefulness, trust, ease of use, e-learning, adoption, e-commerce, and social media.
技术接受模型(TAM)对管理研究具有长期意义。然而,在文献回顾中,技术接受观念的文献演变很少受到关注。很少有研究综述基于整个引文网络对TAM文献的发展和进展进行系统概述,而许多研究综述侧重于通过荟萃分析重新审视TAM各成分之间的联系。本研究探讨了:a) TAM研究在过去30年中是如何演变和扩展的;b) TAM模型已被应用的主要领域;c) TAM研究及其合作的主要贡献者。本文基于Scopus数据库1990 - 2020年间发表的8207篇论文进行文献计量分析,以评估该模型的可行性及其适用性。研究结果表明,早期的TAM研究是由东方和西方学者共同进行的,并且自那以后一直在不断发展并被广泛分享。尽管如此,大多数TAM出版物都集中在计算机科学、社会科学、商业、管理和会计等相同的狭窄领域,而最流行的主题是有用性、信任、易用性、电子学习、采用、电子商务和社会媒体。

With increasing Internet-of-Things (IoT) protocols and connectivity, a growing number of attacks are emerging in the associated networks. This work presents approaches using deep learning (DL) to detect attacks in an IoT environment, particularly in narrowband Internet-of-Things (NB-IoT). By virtue of its low cost, low complexity and limited energy, an NB-IoT device will not likely permit cutting-edge security mechanisms, leaving it vulnerable to, for example, denial-of-sleep (DoSl) attacks. For performance analysis, a NB-IoT network was simulated, using ns-3, to generate a novel dataset to represent an implementation of DoSl attacks. After preprocessing, the dataset was presented to a collection of machine learning (ML) models to evaluate their performance. The considered DL recurrent neural network (RNN) models have proven capable of reliably classifying traffic, with very high accuracy, into either a DoSl attack or a normal record. The performance of a long short-term memory (LSTM) classifier has provided accuracies up to 98.99%, with a detection time of 2.54 x 10-5 second/record, surpassing performance of a gated recurrent unit (GRU). RNN DL models have superior performance in terms of accuracy of detecting DoSl attacks in NB-IoT networks, when compared with other ML algorithms, including support vector machine, Gaussian naïve-Bayes, and logistic regression. 
随着物联网(IoT)协议和连接性的增加,越来越多的攻击出现在相关网络中。这项工作提出了使用深度学习(DL)来检测物联网环境中的攻击的方法,特别是在窄带物联网(NB-IoT)中。由于其低成本,低复杂性和有限的能源,NB-IoT设备不太可能支持尖端的安全机制,使其容易受到拒绝睡眠(DoSl)攻击等攻击。为了进行性能分析,我们使用ns-3模拟了一个NB-IoT网络,生成了一个新的数据集来表示ddos攻击的实现。预处理后,将数据集呈现给机器学习(ML)模型集合以评估其性能。所考虑的DL递归神经网络(RNN)模型已被证明能够以非常高的准确率可靠地将流量分类为ddos攻击或正常记录。长短期记忆(LSTM)分类器的准确率高达98.99%,检测时间为2.54 x 10-5秒/条记录,超过了门控循环单元(GRU)的性能。与其他ML算法(包括支持向量机、高斯naïve-Bayes和逻辑回归)相比,RNN深度学习模型在检测NB-IoT网络中ddos攻击的准确性方面具有优越的性能。

The fifth generation (5G) mobile network technologies include ultra-Reliable Low Latency Communications (uRLLC) capability. To fully exploit uRLLC, distributed Multi- access Edge Computing (MEC) is being developed and introduced at the network edge with an architecture that supports applications and services. Some of the MEC applications will benefit from uRLLC, including virtual reality, augmented reality, education, health, online gaming, automatic manufacturing and Vehicle-to-everything. However, unique challenges and opportunities exist for 5G cellular networks and MEC due to a range of factors, including end-user device mobility and the implementation of the network Control Plane (CP) and User Plane (UP). In this regard, there is a need to optimize protocols and network architecture. This paper investigates latency and related network elements in the next generation mobile cellular network. We also analyze the 5G network latency in the CP and UP. Finally, the paper identifies protocol optimization considerations for MEC integration with 5G to achieve low end-to-end latency.
第五代(5G)移动网络技术包括超可靠低延迟通信(uRLLC)能力。为了充分利用uRLLC,分布式多访问边缘计算(MEC)正在开发和引入网络边缘,其架构支持应用程序和服务。一些MEC应用将受益于uRLLC,包括虚拟现实、增强现实、教育、健康、在线游戏、自动制造和车联网。然而,由于一系列因素,包括终端用户设备移动性以及网络控制平面(CP)和用户平面(UP)的实施,5G蜂窝网络和MEC存在独特的挑战和机遇。为此,需要对协议和网络架构进行优化。本文研究了下一代移动蜂窝网络中的时延及相关网元。我们还分析了5G网络在CP和UP中的延迟。最后,本文确定了MEC与5G集成以实现低端到端延迟的协议优化考虑因素。

Digital Marketing Strategies Driven by Wellbeing in Virtual Communities 虚拟社区幸福感驱动的数字营销策略
Q2 Social Sciences Pub Date : 2022-09-21 DOI: 10.18080/jtde.v10n3.612
Zeineb Ayachi, Rim Jallouli
In the new era ushered in by Covid-19, priority has been given to peoples’ wellbeing. Wellbeing in virtual communities was analysed from several perspectives, such as healthcare, technology, and social science: hence, the importance of a literature review that clarifies how studying health, happiness, comfort and quality of life of virtual communities’ members could guide firms to conceive their digital communication and marketing strategies. This work presents a literature review of papers spanning from 2010 to 2021, and which study digital marketing strategies driven by wellbeing in virtual communities. Results indicate a growing research interest after the pandemic regarding both positive and negative wellbeing dimensions, especially as drivers for digital segmentation, targeting and positioning strategies. Moreover, results highlight the remarkable increase of papers focusing on the tourism industry, game related strategies, and marketing analytics as relevant tools that support digital communication and influence strategies towards virtual communities. Finally, this literature review provides researchers with guidance for future studies in terms of relevant methodologies and areas of research not yet explored.

Regional Mobile Telecommunications Access, Competition and Public Benefits 区域移动通信接入、竞争与公共利益
Q2 Social Sciences Pub Date : 2022-06-30 DOI: 10.18080/jtde.v10n2.595

The Australian Competition and Consumer Commission (ACCC) received an application for merger approval from Telstra Corporation Limited and TPG Telecom Limited related to three interrelated agreements that would put in place a Multi-Operator Core Network (MOCN) arrangement. The three agreements include a MOCN Service Agreement, a Spectrum Authorisation Agreement, and a Mobile Site Transition Agreement. This paper considers the proposed arrangements, identifies that the ACCC’s failure to declare domestic mobile roaming in 2018 was, in some large part, responsible for the market environment that fostered the current proposal, and that the proposed arrangements are not a satisfactory mechanism to fundamentally improve the delivery of reasonably priced, open and competitive, reliable, and high-quality mobile telecommunications in regional and remote areas.
澳大利亚竞争与消费者委员会(ACCC)收到了澳大利亚电信有限公司(Telstra Corporation Limited)和TPG电信有限公司(TPG Telecom Limited)提出的合并批准申请,涉及三个相互关联的协议,这些协议将建立一个多运营商核心网络(MOCN)安排。这三份协议包括MOCN服务协议、频谱授权协议和移动站点过渡协议。本文考虑了拟议的安排,确定了ACCC未能在2018年宣布国内移动漫游,在很大程度上是促成当前提案的市场环境的原因,并且拟议的安排并不是一个令人满意的机制,无法从根本上改善区域和偏远地区提供价格合理、开放和竞争、可靠和高质量的移动通信。

Radio frequency spectrum is a scarce resource, hence its effective and efficient utilization for contemporary and future technologies is of paramount importance. This paper mainly focuses on analysing conventional models for spectrum management, such as command and control and market-based models, and their inefficacy to serve the upcoming technological demands globally. Generally outlined observations concerning spectrum mismanagement include lesser availability of unassigned spectrum and under-utilization of spectrum allocated to passive users. Due to the considerable urge for flexible spectrum assignment framework models and policies, new spectrum assignment approaches, such as Dynamic Spectrum Access, are investigated. Moreover, models such as Licensed Shared Access (LSA), which evolved from Europe, and Citizen Bands Radio Service (CBRS) from North America are also evaluated in this paper as potential choices for future spectrum management in Pakistan. In the aforesaid models, spectrum is shared among multiple users as per time, place and dimensions, keeping in view the security and priority of incumbent and licensed users. In addition, the efficiency of spectrum utilization and economic advantages of these models have also been analysed. Lastly, LSA and CBRS are studied comparatively, and spectrum management suggestions are made for effective implementation in Pakistan.
无线电频谱是一种稀缺资源,因此有效和高效地利用它对当代和未来的技术至关重要。本文主要分析了传统的频谱管理模型,如指挥控制模型和市场模型,以及它们在满足未来全球技术需求方面的不足。关于频谱管理不善的一般性观察包括未分配频谱的可用性较低以及分配给被动用户的频谱利用率不足。由于对灵活的频谱分配框架模型和策略的迫切需求,新的频谱分配方法,如动态频谱接入,被研究。此外,本文还对来自欧洲的许可共享接入(LSA)和来自北美的公民波段无线电服务(CBRS)等模式作为巴基斯坦未来频谱管理的潜在选择进行了评估。在上述模式中,频谱根据时间、地点和维度在多个用户之间共享,同时考虑到现有用户和授权用户的安全性和优先级。此外,还分析了这些模式的频谱利用效率和经济优势。最后,对LSA和CBRS进行了比较研究,并提出了在巴基斯坦有效实施的频谱管理建议。

University Students’ Engagement with Devices and Technology 大学生对设备和技术的参与
Q2 Social Sciences Pub Date : 2022-06-29 DOI: 10.18080/jtde.v10n2.594
L. Cradduck, M. Gregory, L. Campbell
In this paper, through the replication of a pre-COVID-19 research project, we seek to test and compare first-year Australian university students’ study and private uses of technology; compare the desires and capacities of different cohorts (Law and Justice vs Engineering) for technology use; and identify any impacts arising from COVID-19 to their learning experiences. Quantitative and qualitative data, collected by an online questionnaire, identified that, while some participants had more experience with different technologies, there were limited differences between the cohorts’ willingness to use, and their use of, technology for study purposes. Concerns expressed by participants related to where, when, and for what purpose technology was used. Participants all had access to a smart phone, and almost all used a laptop for study purposes. The results suggest the combination of online or pre-recorded lectures and synchronous (either face-to-face or online) tutorials was the most favoured option. While participants were comfortable with the use of technology in teaching and learning, they were wary about using such tools for private communications; however, Zoom and Microsoft Teams, appeared to be in common use. The results confirm the need for a broader and more in-depth understanding of students’ technology uses, needs, and desires.
在本文中,通过复制covid -19前的研究项目,我们试图测试和比较澳大利亚大学一年级学生的学习和私人使用技术;比较不同群体(法律与司法vs工程)对技术使用的愿望和能力;并确定COVID-19对他们的学习经历产生的任何影响。通过在线问卷收集的定量和定性数据表明,虽然一些参与者对不同的技术有更多的经验,但在队列中使用技术的意愿和他们对技术的使用之间存在有限的差异。与会者对技术的使用地点、时间和目的表示关注。所有参与者都可以使用智能手机,几乎所有人都使用笔记本电脑进行学习。结果表明,在线或预先录制的讲座与同步(面对面或在线)教程的结合是最受欢迎的选择。虽然参与者对在教学和学习中使用技术感到满意,但他们对将此类工具用于私人通信持谨慎态度;然而,Zoom和Microsoft Teams似乎是常用的。研究结果证实,需要更广泛、更深入地了解学生的技术使用、需求和愿望。

Quantitative and qualitative data, collected by an online questionnaire, identified that, while some participants had more experience with different technologies, there were limited differences between the cohorts’ willingness to use, and their use of, technology for study purposes. Concerns expressed by participants related to where, when, and for what purpose technology was used. Participants all had access to a smart phone, and almost all used a laptop for study purposes. The results suggest the combination of online or pre-recorded lectures and synchronous (either face-to-face or online) tutorials was the most favoured option.

In a context of overabundance of information on social media, the challenge for an organization is to stand out and to create a link with its target. A Facebook page is a means for a company to federate the users around communities and to drive their engagement. The objective of this research is to test the effect of the use of humour in Facebook posts on perception, attitude and intention of engagement of social media users. An experimental study was conducted on a sample of fans of a Facebook page where we manipulated absence/presence of humour, and humour types. Results show a positive effect of perceived humour on attitude toward the publication, which influences the Facebook user’s intention to engage. Need for humour does not moderate the effect of humour on the attitude and the results do not reveal any difference between the types of humour tested.
在社交媒体上信息过剩的背景下,一个组织面临的挑战是脱颖而出,并与目标建立联系。Facebook页面是公司在社区中联合用户并推动他们参与的一种手段。本研究的目的是测试Facebook帖子中幽默的使用对社交媒体用户的感知、态度和参与意图的影响。我们对Facebook页面的粉丝样本进行了一项实验研究,其中我们操纵了幽默的缺失/存在以及幽默的类型。结果显示,感知到的幽默对对出版物的态度有积极的影响,这影响了Facebook用户的参与意愿。对幽默的需求并没有缓和幽默对态度的影响,结果也没有显示出被测试的幽默类型之间的任何差异。
