This study seeks to explore digital natives' mobile usage behaviors and, in turn, develop an analytic framework that helps articulate the underlying components of mobile addiction syndrome (MAS), its severity levels and mobile usage purposes.

The investigation adopts a survey method and a case study. The results of the former are based on 411 random classroom observations and 205 questionnaire responses, and the insights of the latter are derived from 24 interviews and daily observations.

The findings validate five distinctive signs that constitute MAS and their significant correlations with each of the Big Five personality traits. Classroom observations confirm the prevalence of addiction tendency among digital natives in the research context. Seven levels of MAS and six different mobile usage purposes further manifest themselves from case analysis. There appears to be a sharp contrast between the addicted and non-addicted groups in their mobile purposes and behavioral patterns. Additionally, family relationships seem influential in shaping non-addictive mobile usage behaviors.

Psychological perspectives on MAS may be important but insufficient. Empirical investigation on a global scale, especially with distinctive cross-cultural comparisons, will be highly encouraged. How MAS evolves over time should also serve as future research interests.

Teaching pedagogy of college education might need certain adjustments to intrigue digital natives' learning interests. Future managers might also need to adopt better performance measurements for digital natives who barely separate work from personal matters in their mobile devices.

Parents and healthcare institutions may need to develop response mechanism to tackle this global issue at home and in society. The long-term effects of the COVID-19 pandemic on MAS might also deserve global attention.

The analytic framework developed provides an original mechanism that can be valuable in identifying MAS severity and associated behavioral patterns.

This paper aims to investigate accessibility and usage of mobile smartphones by Arabic-speaking visually impaired people in Saudi Arabia.

In total, 104 participants with visual impairments were interviewed about their use of mobile phones with the following questions: What is the most commonly used mobile phone? What is the popular domain for which they use mobile phones? What are their favorite applications? What accessibility challenges do they usually face while using mobile phones? How often do they use the Internet via mobile phones and what are the reasons behind that?

This research is the first study with such magnitude to investigate smartphone usage by Arabic-speaking visually impaired people. The survey has revealed that Arabic-speaking visually impaired people utilize mobile phones in different ways and strategies. Getting assistance in performing daily tasks and navigating independently are two of the most common uses for mobile phones.

Based on the findings, the authors are going to propose some guidelines to developers to improve smartphone accessibility, application design and Internet usage to improve accessibility for visually impaired people.

This study aims to make the mobile robot better adapt to the patrol and monitoring in industrial field substation area, a multi-mode mobile carrying mechanism which can carrying data collector, camera and other equipment is designed.

Based on the geometric axis analysis and interference analysis, the multi-mode mobile carrying mechanism is designed. The screw constraint topological theory and zero-moment point (ZMP) theory is used to kinematic analysis in mechanism mobile process.

The mobile carrying mechanism can realize the folding movement, hexagonal rolling and quadrilateral rolling movement. A series of simulation and prototype experiment results verify the feasibility and actual error of the design analysis.

The work of this paper provides a mobile carrying mechanism for carrying different data acquisition equipment and surveillance camera in industrial field substation zone. It has excellent folding performance and mobile capabilities. The mobile carrying mechanism reduces the workload of human being and injuries suffered by workers in industrial substation area.

This paper aims to provide an in-depth analysis of the process of standards setting based on the case of long-term evolution time division duplex (LTE TDD) deployment in China.

Using actor-network theory (ANT) as a theoretical framework, multi-level analyses are presented to explain the process of adoption of LTE TDD at a global level.

Findings identified the complex interaction between the social and technical aspects of fourth-generation (4G) by highlighting the co-evolving nature, diversity and interface that constitute the next-generation network environment.

ANT provides a framework of ideas for describing the process of technology adoption and for developing stories that explain it.

The findings shed light on a critical insight of the interrelationships between TD-SCDMA and LTE TDD and identify the policy successes and failures of 4G mobile networks.

This study aims to expand previous work on website stage models by proposing a new model including a dimension encompassing digital integration and the context of mobile, digital marketing and new technologies. Also, this study aims to classify Brazilian wineries using the stage model proposed and verify if the designated stages influence the wineries’ presence in digital and mobile media.

Observational research and quantitative content analysis were adopted to examine a sample of winery websites (N = 150) located in different states and regions of Brazil and create a new website stage model. After the new model’s development, the authors conducted a statistic analysis by running a one-factor analysis of variance to assess the influence of the company’s stage in the use of digital media and mobile strategies, as well as its impacts on market development.

The results suggested a quite mature market regarding website stage position, even though there is still room for growth and technological innovation. Also, the research findings show that there is a positive association between the company’s stage in the use of digital and mobile media strategies. In other words, the more advanced the winery stage, the greater its digital media and mobile presence.

While previous studies attempted to identify wineries’ stages through models, this study presents a new approach by updating the past studies’ stages as well as providing and testing a digital media and mobile dimension. This research contributes to consolidating the Brazilian wine industry position regarding its presence in digital and mobile media, bringing reflections to organizations, society and theory development.

The purpose of this paper is to focus on the relationship between the corporate governance (CG) environment, governance behavior and governance performance and place it into the research of the evolution and revolution of the Chinese telecommunication industry, a complex economic system.

On the basis of information about the Chinese telecommunication industry from 1949 to 2009 and China Mobile from 1997 to 2007, the authors analyze the Chinese telecommunication industry from two levels, namely industry level and firm level, with the combination of a critical incident method and time series method.

The results demonstrate that the evolution of the Chinese CG environment and governance behavior presents characteristics of punctuated equilibrium; governance behavior lags behind governance environment and it can cause the governance environment to evolve to benefit its development through exerting active effects; governance environment and governance performance strongly relate to and have an effect on each other; and the improvement of governance structure and mechanisms, together with the enhancement of strategic capability, can greatly contribute to the governance performance of firms.

This paper has divided the development of the Chinese telecommunication industry into four stages, revealing the relationship between governance environment, governance behavior and governance performance with a case study of the Chinese telecommunication industry and China Mobile.
