Prohibitive factors to the acceptance of Internet of Things (IoT) technology in society: A smart-home context using a resistive modelling approach

With the advent of various Internet of Things (IoT) technologies, smart-homes have become an important application area. However, the low end-user penetration of the smart-home market as of 2021 points out towards the fact that the users are resistant to use home IoT and smart-home solutions. Privacy concerns is an important factor that hinders the smart-home adoption as per existing literatures. Unfortunately, current smart-home literatures have not focused enough on the theoretical aspect of the privacy concern construct per se, what are its various antecedents, and what constitutes the users’ privacy concerns. Consequently, in this work a resistive modelling approach is used focusing on the privacy aspect that hinders the diffusion of IoT-based smart-homes in the society. Innovation Resistance Theory (IRT) and Multidimensional Development Theory (MDT) are used as the theoretical background. Multiple antecedents of privacy concern are considered ranging from individual (user skill), technological to environmental factors (legal & policy aspect). Moreover, privacy concern is treated from three aspects of informational privacy, physical privacy, and psychological privacy. The proposed model is validated and tested using data collected from 463 users residing in Thailand. The differences in privacy perception and its effect on user resistance depending on gender and residence type is also discussed. Results show that the user characteristics of user skill has the highest impact on privacy concern, followed by legal & policy aspect, and technological aspect respectively. Moreover, physical, and psychological privacy are more important than informational privacy concerns. Appropriate theoretical and practical suggestions are provided based on the results.     

How people access the internet and the democratic divide: Evidence from the Chilean region of Valparaiso 2017, 2018 and 2019

The Internet has been often described as a tool that fosters the inclusion of traditionally marginalized people in the democratic process. Yet, if the type of device used by people to access the Internet impacts their online democratic engagement, uneven Internet penetration and differences in the devices used by social groups will result in a deeper democratic divide. After discussing the impact of the types of internet use and type of access devices on civic engagement, we postulate 3 hypotheses on how democratic values and type of access to the Internet—place and devices—are related to the civic use of social media. We use data from a Valparaíso Regional poll in Chile in 2017, 2018 and 2019 to test those hypotheses. People who access the Internet via mobile phones are less likely to use social media with a civic purpose, while those who access the Internet at home or work are more likely to do so. Since low-income sectors primarily access the Internet via mobile phones while higher income groups have a wider array of Internet connection options, the rapid growth of cell phone use for accessing the Internet risks deepening social and income gaps in civic engagement.     

How Do People Value Data Utilization?: An Empirical Analysis Using Contingent Valuation Method in Japan

In this study, we tested the following three hypotheses regarding the data utilization of online services: 1) Service users are concerned about the data utilization of service providers, and there exists a privacy paradox. 2) Consumer evaluations of data utilization are diverse, and some service users are positive about data utilization. 3) People with familiarity with the Internet are more positive about data utilization. In order to quantitatively measure people's evaluation of data utilization, we used contingent valuation method (CVM) in a survey by questionnaire of 5986 people to find out their willingness to pay for data utilization. The results of the empirical analysis show that all hypotheses were supported. We can obtain the following two policies and service providers implications. First, there is a privacy paradox with respect to data utilization, so the service providers need to create an environment where people can choose the level of data utilization. Second, it is necessary to design a rule that takes diverse values into account.     

Non-iterative privacy preservation for online lotteries

Unlike gambling, lottery games can exist in a lawful form to raise funds for charitable institutions. Owing to the expeditious development of network technology, lotteries over the Internet have become an inevitable trend. Since the Internet allows people to communicate with each other without direct contact, it is more difficult to guarantee the security and fairness of online lotteries than for conventional lottery games. However, electronic lottery methods can also provide something that conventional lottery mechanisms cannot: they allow players to purchase tickets at any time and in any place where they can access the Internet. The authors propose an online lottery mechanism that can confirm the propositions of general lottery games. Specifically, this novel method not only allows players to make t-out-of-n numbers in lotteries without iterative selection but also preserves the privacy of players' choices, making the system more similar to traditional lottery games.

Why do people want to use location-based application for emergency situations? The extension of UTAUT perspectives

This study aims to determine the factors that influence user intention to use location-based emergency applications. The Unified Theory of Acceptance and Use of Technology (UTAUT) is used as a fundamental theory by adding other relevant variables: trust, privacy concern, and fear of crime. Data were collected through questionnaires distributed to the users of the X-Igent Panic Button application. A total of 348 data were collected online using random sampling and processed using structural equation modeling. This study concludes that this application adoption's determinant factors are performance expectancy, trust, social influence, fear of crime, and collection as privacy concerns. These factors become significant predictors of behavioral intention by explaining about 60.5% of the total variation. The study also concludes that trust in services or service providers has the most significant positive impact on the behavioral intention to use location-based mobile applications in emergencies.     

Investigating the effect of online and offline reputation on the provision of online counseling services: A case study of the Internet hospitals in China

The sustainable development of Internet hospitals and e-health platforms relies on the participation of patients and physicians, especially on the provision of health counseling services by physicians. The objective of our study is to explore the factors motivating Chinese physicians to provide online health counseling services from the perspectives of their online and offline reputation. We collect the data of 141029 physicians from 6173 offline hospitals located in 350 cities in China. Based on the reputation theory and previous studies, we incorporate patients’ feedback as physicians’ online reputation and incorporate physicians’ offline professional status as physicians’ offline reputation. Results show that physicians’ online reputation significantly and positively influence their online counseling behaviors, whereas physicians’ offline reputation significantly and negatively influence their online counseling behaviors. We conclude that physician’s online and offline reputations show a competitive and substitute relationship rather than a complementary relationship in influencing physicians to provide online counseling services in Internet hospitals. One possible explanation for the substitute relationship could be the constraints of limited time and effort of physicians.     

Public benefit and risk perceptions of nanotechnology development: Psychological and sociological aspects

Nanotechnology enables the development of new and improved products. However, the public is also concerned about uncertain risks associated with nanotechnology-enabled products. To address this concern, the study aims to expand the understanding about public benefit and risk perceptions as a basis for the effective formulation of policy that addresses public interests. The study investigates public benefit and risk perceptions of nanotechnology development from the psychological and sociological aspects through a questionnaire survey conducted on Klang Valley, Malaysia. Analysis of variance (ANOVA) illustrates that demographics indeed influences public benefit and risk perceptions of nanotechnology development. However, public knowledge about nanotechnology exerts no effect on public benefit and risk perceptions of nanotechnology development based on independent t-tests. Simple linear regression reveals that the lack of public trust in government increases risk perception. Public attitude perceives nanotechnology to be more beneficial than risky, thus influencing benefit perception rather than risk perception. Public lifestyle, such as culture, religious beliefs and social group influence benefit perception but not risk perception. Result is expected to deliver better communication of benefit and risk of nanotechnology to the public as well as ensure an ethical policy regarding nanotechnology development.     

Continuance in online participation following the compromise of older adults’ identity information: a literature review

ABSTRACT

This paper presents findings from a literature review on older adults continued use of the Internet following an identity theft incident. Globally, identity theft is increasing, statistics show that the number of older adults falling victim to identity theft is growing. Victims of identity theft suffer emotional, physical, psychological, and social problems; many change their behaviour as a result. The aim of the review was to examine literature to determine what is known regarding how older adults use the Internet and/or modify their online behaviour following an identity theft event. It was found that knowledge is lacking regarding the impact that identity theft events have on older adults’ continuation of Internet use. Little research has been undertaken to understand the factors and interrelationships that contribute to the situation. The review highlights that a systems ergonomics approach should be considered as an appropriate framework to drive future research in this area.
