Insider threats are one of the major potential risks jeopardizing organizational security. Many organizations have applied opportunity-reducing techniques to enhance security. These techniques have been classified into hard and soft forms based on their potential propensity to infringe on employees’ personal space. Hard form techniques have been widely adopted owing to their efficiency in saving cost and time. However, this study argues that hard form techniques would restrict personal autonomy, leading employees to disrespect the organizational security policies. To test the research hypotheses, a scenario-based questionnaire survey was conducted on 5,158 Prolific Academic members with working experience in the service industry and research and development, and the information industry. Two hundred and fifty-nine valid responses were analyzed using partial least square based structural equation modeling (PLS-SEM). The results show that the hard form techniques induce employees to feel intrusion of their privacy, making them morally irresponsible for their behavior, and even committing an insider attack. Hard form techniques can produce an adverse effect that is opposite to the intended purpose. The results imply that the practical method of making hard controls less intrusive, including the implementation of soft controls and horizontal decision-making processes for security policies, should be explored.

Digital transformation refers to the unprecedented disruptions in society, industry, and organizations stimulated by advances in digital technologies such as artificial intelligence, big data analytics, cloud computing, and the Internet of Things (IoT). Presently, there is a lack of studies to map digital transformation in the environmental sustainability domain. This paper identifies the disruptions driven by digital transformation in the environmental sustainability domain through a systematic literature review. The results present a framework that outlines the transformations in four key areas: pollution control, waste management, sustainable production, and urban sustainability. The transformations in each key area are divided into further sub-categories. This study proposes an agenda for future research in terms of organizational capabilities, performance, and digital transformation strategy regarding environmental sustainability.

The main sources of technological development are from abroad rather than domestic in many countries. The global networks for knowledge and technology flows are becoming sophisticated. This article examines how a country's embeddedness in the global knowledge spillover networks, particularly trade and FDI, is related to national innovation performance. Network closure and structural hole, the main arguments in network theory literature, represent the main objectives of our network analysis. The results are subsequently used to assess how these network characteristics are related to national innovation performance via panel negative binomial regression analysis. The findings show an overall tendency of a negative effect of network closure and a positive one of structural holes on a country's innovative outcome. In conclusion, this article not only highlights the significant role of network characteristics in national innovation performance, but also provides implications on how to leverage such network resources to improve national innovation systems.

The need to create and deploy business application systems rapidly has sparked interest in using web services to compose them. When creating mission-critical business applications through web service compositions, in addition to ensuring that functional requirements are met, designers need to consider the end-to-end reliability, security, performance, and overall cost of the application. As the number of available coarse-grain business services grows, the problem of selecting appropriate services quickly becomes combinatorially explosive for realistic-sized business applications. This article develops a business-process-driven approach for composing service-oriented applications. We use a combination of weights to explore the entire QoS criteria landscape through the use of a multi-criteria genetic algorithm (GA) to identify a Pareto-optimal multidimensional frontier that permits managers to trade off conflicting objectives when selecting a set of services. We illustrate the effectiveness of the approach by applying it to a real-world drop-ship business application and compare its performance to another GA-based approach for service composition.

Digital technology allows people to participate in various social activities easily. In politics, online crowdfunding has been gaining attention because it gives politicians benefits to raise political funds from the public. It is also convenient for backers to donate money to support their chosen politicians. This study examines the factors driving people’s intention to participate in online political crowdfunding. By employing the civic voluntarism model and cognitive dissonance theory, this study develops an integrated model to explain people’s intention to participate in online political crowdfunding. The results show that perceived congruence between politicians and individuals is one of the most influential driving factors for online political crowdfunding participation. The findings further reveal that perceived congruence is lowered by individuals’ negative perception of the political situation. This research proposes important implications for researchers as well as practitioners to promote online crowdfunding not only in politics but also in other domains.

Social Network Service (SNS) users are more incidentally exposed to heterogeneous expressions than those engage in off-line discussion networks. The literature has mainly focused on how participation in social media affects users' subjective well-being, while overlooking how the heterogeneous expression on social media affects the users' subjective well-being and consequent behaviors on SNS. Underlining the undesirable consequences of the users’ exposure to opposing views, this study developed a conceptual cognitive framework on the theory of cognitive dissonance, the extreme discomfort of simultaneously holding two conflict thoughts, and showed the existence of mental discomfort of the user in the face of heterogeneous opinions. We also discussed the kind of strategic behaviors the users may take to resolve the uncomfortable psychological state. To test, we first utilized projective technique to measure the uncomfortable psychological states of the respondents, and applied a covariance based structural equation modeling (CB-SEM) methodology with 425 questionnaire responses collected from Prolific Academic (Prolific.ac). We found that the more the users use social media, the more often they are exposed to opposite opinions and the more uncomfortable they feel. In order to resolve these uncomfortable feelings, it appears that these users tend to take selective exposure more than affective behavior. Robustness tests were conducted to check the controlling effects of personality traits and demographic variables on the main variables.

Despite the growing importance of developing countries to the global economy and their increasing role in innovation, limited academic attention has been given to the national innovation systems (NIS) of these countries. Given that they commonly suffer a lack of resources, efficiency in the operation of innovation seems crucial. This study aims to assess the innovation efficiency of developing countries. Breaking down the NIS into two stages, knowledge production and application process, we additionally introduce the knowledge absorption perspective in the latter stage as the consideration for the context of developing countries. Based on the results of the efficiency assessment, clustering analysis is implemented to identify several typologies of the operation of NIS in developing countries and to provide implications for each case. This study will constitute a meaningful attempt to provide a general understanding of innovation status and operations in developing countries, thereby suggesting policy directions for several cases.

A wide range of studies in various disciplines has focused on the Internet of Things (IoT) and cyber‐physical systems (CPS). However, it is necessary to summarize the current status and to establish future directions because each study has its own individual goals independent of the completion of all IoT applications. The absence of a comprehensive understanding of IoT and CPS has disrupted an efficient resource allocation. To assess changes in the knowledge structure and emerging technologies, this study explores the dynamic research trends in IoT by analyzing bibliographic data. We retrieved 54,237 keywords in 12,600 IoT studies from the Scopus database, and conducted keyword frequency, co‐occurrence, and growth‐rate analyses. The analysis results reveal how IoT technologies have been developed and how they are connected to each other. We also show that such technologies have diverged and converged simultaneously, and that the emerging keywords of trust, smart home, cloud, authentication, context‐aware, and big data have been extracted. We also unveil that the CPS is directly involved in network, security, management, cloud, big data, system, industry, architecture, and the Internet.

The increase in data traffic calls for investment in mobile networks; however, the saturating revenue of mobile broadband and increasing capital expenditure are discouraging mobile operators from investing in next‐generation mobile networks. Mobile network sharing is a viable solution for operators and regulators to resolve this dilemma. This research uses a difference‐in‐differences analysis of 33 operators (including 11 control operators) to empirically evaluate the cost reduction effect of mobile network sharing. The results indicate a reduction in overall operating expenditure and short‐term capital expenditure by national roaming. This finding implies that future technology and standards development should focus on flexible network operation and maintenance, energy efficiency, and maximizing economies of scale in radio access networks. Furthermore, mobile network sharing will become more viable and relevant in a 5G network deployment as spectrum bands are likely to increase the total cost of ownership of mobile networks and technical enablers will facilitate network sharing.

This study examines how the characteristics of cooperative research and development (R&D) projects in the public domain impact information and communication technology (ICT) convergence. Based on the analysis of 416 cooperative R&D projects under the ICT-based industry convergence R&D program in Korea, the study finds that the characteristics of cooperative R&D projects significantly impact ICT convergence. Moreover, the participation of public research institutes and universities is critical for ICT convergence compared with that of firms. However, in firm-to-firm cooperation, the participation of small and medium enterprises contributes to cross-sectional convergence, while the participation of large firms leads to overall and longitudinal convergence. R&D inputs such as the number of partners and government subsidies exhibit an inverted U-shaped relationship (negative quadratic effect) with technology convergence. Project duration and homogeneous partners are also critical factors for ICT convergence. The results indicate several implications and guidelines on how to effectively organize cooperative R&D projects to facilitate technology convergence.

This study examines makerspace continuance intention using self-determination theory.Technical, economic, and social support enhance a users basic psychological needs.Psychological need fulfillment increases intrinsic motivation. Makerspaces are informal physical spaces located in community settings or educational institutions where people immerse themselves in creative making. Makerspaces hold incredible potential for fostering essential skills needed for the future and are increasing in number worldwide. Previous research has identified many diverse makerspace initiatives and has demonstrated their potential, but few research has examined makerspace sustainability. Makerspace sustainability is a significant issue as diminished participation, activity, utilization, and retention limit its success. This study examines makerspace sustainability by understanding which factors influence makerspace continuance intention. This study proposes and empirically tests a conceptual framework based on self-determination theory to identify the motivations of makerspace users. An analysis of data collected from 121 South Korean makerspace users indicates that makerspace environmental support is significantly related to a makerspace users basic psychological needs. Those psychological needs positively impact intrinsic motivation, which ultimately influences makerspace continuance intention. This research has several implications for academics while recommendations are proposed that have immediate application for practitioners which are informed by the study results.

Media tablets have been one of the most innovative and popular mobile devices with the rapid development of mobile computing technology. The purpose of this study is to offer a clear understanding of the overall adoption processes by starting from the characteristics of a media tablet to adoption intention via perceived value. This study investigates the relationships between the value of media tablet (e.g., usefulness, enjoyment, social image, and risk) and the product characteristics (e.g., design, functionality, contents, brand, and price). Perceived benefits including perceived usefulness, perceived enjoyment, and social image seem to have a greater impact than the level of perceived sacrifice on perceived value. Perceived usefulness is the strongest factor determining adoption intention through perceived value. An innovative design affects social image, and brand name positively affects both perceived usefulness and social image. Functionality and content have a positive influence on both perceived usefulness and enjoyment. Price positively affects perceived risk. This research also finds that smartphone experience moderates the effect of perceived usefulness on perceived value, and personal innovativeness offsets the negative effect of perceived risk on perceived value as a moderator. These findings contribute a number of implications for academia and practitioners.

Purpose The purpose of this paper is to extend the theory of consumption values by investigating the influence of aesthetic, conditional, convenience, monetary, epistemic, self-gratification, and social value on customer pre-adoption choice behavior to use mobile financial services. Design/methodology/approach Data were collected using an online survey questionnaire resulting in 524 total responses from registered users of M-PESA mobile financial services in Kenya, ultimately resulting in a usable sample of 384 responses. Partial least squares was used to evaluate the research model and associated hypotheses. Findings Aesthetic, conditional, convenience, monetary, epistemic, and self-gratification value are positive determinants of customer pre-adoption choice behavior to use M-PESA mobile financial services, but not social value. Research limitations/implications Survey participants were limited to customers of M-PESA mobile financial services in Kenya. The study findings present important implications for managers and academic researchers in the mobile financial services market. Originality/value This is one of the first empirical studies to investigate customer pre-adoption choice behavior to use M-PESA mobile financial services from the perspective of customer perceived value.

Purpose The purpose of this paper is to develop a comprehensive research model that can explain potential customers’ behavioral intentions to adopt and use smart home services. Design/methodology/approach This study proposes and validates a new theoretical model that extends the theory of planned behavior. Partial least squares analysis is employed to test the research model and corresponding hypotheses on data collected from 216 survey samples. Findings Mobility, security/privacy risk, and trust in the service provider are important factors affecting the adoption of smart home services. Practical implications To increase potential users’ adoption rate, service providers should focus on developing mobility-related services that enable people to access smart home services while on the move using mobile devices via control and monitoring functions. Originality/value This study is the first empirical attempt to examine user acceptance of smart home services, as most of the prior literature has concerned technical features.

Technological development in the past decade has motivated governments in developing countries to focus on leveraging new technologies for efficient and effective public service delivery. M-government has been singled out as one of the fundamental aspect for socio-economic growth in developing countries. Therefore, this study aims at investigating the factors that influence individuals in adoption of new technology, specifically m-government in the context of developing countries. Precisely, this study was to present and empirically validate a research model based on user behavior that examine m-government acceptance in developing countries and inspect the moderating role of facilitating conditions on m-government adoption. The research model was tested using data from 248 respondents from Kenya, surveyed between August and September 2011. The results indicated that the proposed model explained a variance of 60.5 percent of behavior intention to use m-government. In addition, facilitating conditions were found to be a crucial spur to m-government acceptance in developing countries.

Firms continuously search for external knowledge that can contribute to product innovation, which may ultimately increase market performance. The relationship between external knowledge sourcing and market performance is not well-documented. The extant literature primarily examines the causal relationship between external knowledge sources and product innovation performance or to identify factors which moderates the relationship between external knowledge sourcing and product innovation. Non-technological innovations, such as organization and marketing innovations, intervene in the process of external knowledge sourcing to product innovation to market performance but has not been extensively examined. This study addresses two research questions: does external knowledge sourcing lead to market performance and how does external knowledge sourcing interact with a firm’s different innovation activities to enhance market performance. This study proposes a comprehensive model to capture the causal mechanism from external knowledge sourcing to market performance. The research model was tested using survey data from manufacturing firms in South Korea and the results demonstrate a strong statistical relationship in the path of external knowledge sourcing (EKS) to product innovation performance (PIP) to market performance (MP). Organizational innovation is an antecedent to EKS while marketing innovation is a consequence of EKS, which significantly influences PIP and MP. The results imply that any potential EKS effort should also consider organizational innovations which may ultimately enhance market performance. Theoretical and practical implications are discussed as well as concluding remarks.

This study develops a research model that explains the continuance of corporate SNS pages. To find antecedents that influence end-users’ continuance intention, this study adopts communicative ecology theory from media and communication studies. Results indicate that the quality of social interaction is the most salient factor, as indicated by the fact that it has the greatest impact on perceived usefulness and enjoyment. Moreover, content quality also increases both perceived usefulness and enjoyment, while SNS platform quality and service quality increase perceived usefulness only. In addition, perceived network size moderates the impact of social interaction quality on perceived enjoyment.

The successful assimilation of group decision support systems (GDSS) in the Command, Control, Communications, Computers, and Intelligence (C4I) systems of military organizations is critical for making fast and accurate modern military operations decisions. This study empirically examines factors affecting military group decision support systems’ (MGDSS) assimilation and the mediating effect of structural appropriation in the Korean Army in a technology-organization-environment (TOE) framework. Two hundred and forty-eight users or former users of the Army Tactical Command Information System (ATCIS) participated in the survey and a partial least squares (PLS) analysis was used to analyze the data. The results found that institutional pressure (IP) has the strongest effect on structural appropriation, followed by IT infrastructure (ITI) and top management support (TMS). Structural appropriation plays a significant mediating part between the TOE factors and MGDSS assimilation. The results provide implications and contribute valuable insights for military organizations’ successful assimilation of MGDSS.
