This study measures individual resilience to cyberterrorist attacks on financial systems and explores the antecedents of resilience. The research model integrates the resilience literature with the fear appraisal literature to address individuals’ fears of cyberterrorist attacks on financial systems. The model is tested using data collected through an online survey. The results show that (1) community support and family financial management significantly increase resilience toward cyberterrorist attacks, and (2) resilience to and fear of cyberterrorist attacks significantly influence individuals’ behaviors in handling their finances. This research helps IT practitioners to develop strategies to build cyber resilience capacities among individuals and communities.  相似文献

This study proposes and validates a new industry taxonomy to understand the use of IT that generates superior economic returns based on the specific economic and competitive characteristics of four different industry types and the strategic role of IT in each of these industry environments. Our findings extend the well-established industry taxonomy on the strategic role of IT (Automate, Informate, Transform) by considering how IT is changing the nature of the product/service in industries where transformational logics prevail. We found that in industries where the product/service is digital in nature, the firms that achieve higher economic returns are those where IT is used to support dual strategies based on the integration of cost leadership and differentiation. Conversely, in other industries – with the exception of those producing commodities – the firms that achieve superior returns are those that use IT to support differentiation. The results of this study can help managers make intelligent decisions about competitive strategies and IT investments, depending on the business environment of the sector in which the firm operates and the generative potential of emerging technologies to do new things.  相似文献

Early depression detection can enable timely intervention. Automatic depression detection has relied on features extracted from individual-level data, which may be too coarse to support effective detection. Existing detection models have largely overlooked interview questions commonly used in clinical depression assessment. This research proposes a two-layered multi-modal model for depression detection, which not only extracts features from responses at a level of individual interview questions, but also identifies semantic categories of those questions. The evaluation results demonstrate that the proposed model outperforms the state-of-the-art methods for depression detection. The research findings have broad and cross-disciplinary implications.  相似文献

This paper explores the role of citizen journalism in the improvement of slums through the Voice of Kibera (VoK) case study. To meet the research objectives, both qualitative and quantitative methods are applied. The study used content analysis, a survey and interview techniques. It concluded that citizen journalism in the VoK uses a participatory, bottom-up approach, with the residents taking a lead role in the production and consumption of news, and that it plays its part in improving the lives of people in Kibera, contributing to governance and processes of democracy. The core development values of participation and empowerment are central to this study, which examines how these values are being impacted on by information technology interventions in the communications area. The research also concludes that citizen journalism may be sustainable if it is financed, promoted, resourced with professional journalists, equipped with new technologies and citizens continue to participate. Lack of cooperation from the audience, finance both for the running of the project, salary and technical problems were cited as the major challenges of citizen journalism.  相似文献

Rather than tackle one particular topic in detail, this article will consider where IT security has got to across several fronts — in some areas considerable progress has been made, systems are “more” secure now than a few years ago. In other areas however, little has changed; the problem has just been moved around or hasn’t really been effectively solved. Certainly the threat landscape has changed, modern attacks are often intriguingly clever and powerful (witness the breadth of distribution mechanisms that the NIMDA virus used, the use of SQL injection against websites etc…). Technology has also presented further opportunity — just look at the flurry of threats that have surrounded wireless networks since their inception.  相似文献

This study investigated the compatibility of stimulus codes and response modalities and how it mediated the spatial Stroop effect. Stimulus code (word, arrow and moving dots), response modality (voice, keypress and mouse movement), directional information (left and right) and physical location (centre, left and right) of the stimulus were manipulated. Participants responded to the directional information of the stimulus. Spatial interference was expected when the stimulus’ directional information and physical location were incongruent. Results showed that more compatible pairings for the three response modalities were word–voice, arrow–keypress and arrow–movement. Incongruent spatial location delayed the reaction time for all response modalities with the word, speeded up the vocal and keypress responses with the moving dots, and had no effect with the arrow. Arrow was thus recommended for conveying directional information on interfaces. This study demonstrated that spatial interference was mediated by the stimulus code, response modality and their compatibility.  相似文献

With the wide diffusion of information technology (IT) in our daily life and work, it is clear that product innovation and service innovation have more and more connection with IT, and IT has become an important tool or component in innovation. The purpose of this paper is to provide insights into future studies pertaining to this area by investigating the research development of IT innovation using bibliometric analysis. The status of IT innovation study is analysed through citation analysis with the help of CiteSpace. Influential references, hot topics, top-tier journals and important institutes are all detected, and the intellectual structure of recent studies is also mapped in this study, and we find that research on IT innovation is mainly from two directions, innovation study group and information systems study group. Finally, we follow the logic of Nambisan [2013. “Information Technology and Product/Service Innovation: A Brief Assessment and Some Suggestions for Future Research.” Journal of the Association for Information Systems 14 (4): 215–226] to explore the relationship between IT and innovation through reviewing papers in the top journals in this field. We find that most studies treat IT as an enabler of innovation. Although some recent studies try to pay attention to the role of IT as a trigger for innovation and give some rationale for the IT–innovation relationship, further studies are still required to uncover the trigger effect mechanism.  相似文献

Much computer science literature addresses the mechanics of the Unified Modelling Language (UML) and requirements modelling, but little research has addressed the role of UML in the broader organizational and project development context. This study uses a socio-technical approach to consider UML as a technology embedded in a social environment. In this study, project developers were interviewed in detail about their use of UML along with influences on their decisions to use this approach and the results of using it. Data were analyzed using causal mapping. Major findings included: (1) that definitions of success may differ by unit of analysis (e.g., developer, project, organization) and that the relationship among these definitions are complex; (2) a very large number of variables impacting project success were identified; (3) a number of important variables exist in complex (non-linear) relationships with project success; and (4) the majority of interviewees linked the use of UML to project success.  相似文献

Given that the Internet does not afford an opportunity to inspect products before purchase, some customers hesitate to shop online. Online interactivity can supplement online decision-making with added product information. Based on the theories of impression management and deception, this study focuses on sellers’ online interactivity strategies (SOIS) and aims to explore the role of SOIS played in online purchase decision-making process. According to the stimulus–organism–response (S–O–R) paradigm, this study aims to understand how each component of SOIS affects transaction intention through consumer perceptions (perceived deception and perceived diagnosticity) and how this affect is moderated by product types (search goods and experience goods) in online marketplaces. Data collected from 475 respondents support most of our hypotheses. Product type positively moderates only the link between image creation and perceived deception. Implications for theory and practice are also discussed.  相似文献

This paper examines the potential role of gatekeepers’ innovative use of information technology (IT) in organizational units and its ability antecedents. Using absorptive capacity theory as our theoretical lens, we theorize a model of innovative use of IT at the unit level. The proposed model was empirically validated using a survey of 204 unit gatekeepers. This paper develops a preliminary model of innovative use of IT that can inform and guide future research, specifically focusing on the key role of gatekeepers and the abilities needed by users in this role that can help in using IT in an innovative manner.  相似文献

Recent developments in information and communication technology have blurred the line between the workplace and the home. This can have a negative influence on employees' well-being and thus has gained increasing attention from academics and practitioners. In this study, we developed a research model based on the transactional perspective of stress and the challenge–hindrance stressor framework. We defined the two dimensions of work–family conflict as the perceptual stress resulting from a chronic challenge and hindrance technostressors, which ultimately affect employees' satisfaction in both the work and family domains. We tested our model using a three-wave time-lagged survey study with data collected from 268 employees. Challenge and hindrance technostressors had different effects on these two main forms of work–family conflict (time-based and strain-based) but further induced negative effects on both job and family satisfaction. Overall, we make both scientific and practical contributions to the fields of work-related technology use and work–family conflict.  相似文献

I investigated the role of IT governance in driving the success of ERP projects. The tool for assessing ERP value was a comprehensive, multivariate and validated model adapted from the widely used Delone and McLean model of IS success. This showed that ERP investments were more effective in organizations having an IT governance domain consisting of proactive strategic guidance and participatory team building. Large enterprises, however, under-performed compared to SMEs and needed specific performance drivers, such as top management commitment to become effective.  相似文献

The purpose of this study is to better understand the digital divide by identifying the variety of ways in which people in Europe use the Internet. First, by using cluster analysis on survey data (N=12,666/age: 16–74 years) from Eurostat on Internet usage in Norway, Sweden, Austria, the UK, and Spain, we identified five user types: Non-Users (42%), Sporadic Users (18%), Instrumental Users (18%), Entertainment Users (10%), and Advanced Users (12%). These user types differ in their distributions over country, age, access, household members, and gender. An alarming finding is that 60% of the population was found to be either Non-Users or Sporadic Users, which reflects a large digital divide in Europe. Second, we conducted a logistic regression to identify the predictors for different user types. We found on a cross-national level that age and Internet access are the most salient predictors, whereas gender and household seems to be less relevant. However, the amount of variance explained differs between countries. We also suggested a future increase in the digital divide between the identified user types—a user type divide. The user typology and the identified predictors might help researchers, practitioners, and decision makers to better understand Internet users and the multi-complex variations among individuals and countries. This knowledge will also serve as a means to understand the digital divide by providing a more nuanced perspective on Europeans' unequal usage of the Internet and participation in an increasingly digital society.  相似文献

We examined the positive impact of transformational leadership on IS success in organizations via two psychological mechanisms of system users’—perceived organizational support and systems self-efficacy. Our conceptual model was assessed using a sample of 251 employees from a multi-national bank in Korea. Overall, our results supported the hypothesized relationships: transformational leadership was positively related to system users’ IS success, and both perceived organizational support and systems self-efficacy of the system users mediated the relationship between transformational leadership and IS success. The results call for manager's attention to the importance of transformational leadership development in organizations.  相似文献

Abstract

The understanding and applications of scientific and everyday knowledge by high school students was documented among 52 secondary students in Kenya. The study utilized a socio-cultural framework, a pre- and post-data-collecting strategy, and theme building in data analysis. Posttest data showed an increase of claims that referred to the conduct of scientific inquiry or systematic “finding out.” It appears that the content of the lecture prompted students’ to consider using scientific knowledge to solve problems in everyday life. The implications of the study point to a reconsideration of the practices of science education in Kenya and similar contexts.  相似文献

While researchers have increasingly recognized the importance of information technology (IT) in leveraging a firm’s competitive strategy for achieving superior firm performance, our understanding of the nature of how a firm’s competitive strategy aligns with its industry IT strategic role and how such alignment influences firm performance remains limited. Drawing upon strategic alignment perspective, this study aims to theorize and empirically test how the firm’s competitive strategy (i.e., cost leadership, differentiation, and dual strategy) aligns with its industry IT strategic role to improve firm performance. Based on the data of Chinese publicly listed firms during 2009–2015, our results indicate that different competitive strategy aligns with different industry IT strategic roles for achieving superior performance. Specifically, cost leadership strategy aligns with automate IT strategic role, dual strategy aligns with informate IT strategic role, and differentiation strategy aligns with transform IT strategic role in generating superior firm performance. We also discuss the theoretical and practical implications of the current study.  相似文献

Although e-commerce adoption and customers’ initial purchasing behavior have been well studied in the literature, repeat purchase intention and its antecedents remain understudied. This study proposes a model to understand the extent to which trust mediates the effects of vendor-specific factors on customers’ intention to repurchase from an online vendor. The model was tested and validated in two different country settings. We found that trust fully mediates the relationships between perceived reputation, perceived capability of order fulfillment, and repurchasing intention, and partially mediates the relationship between perceived website quality and repurchasing intention in both countries. Moreover, multi-group analysis reveals no significant between-country differences of the model with regards to the antecedents and outcomes of trust, except the effect of reputation on trust. Academic and practical implications and future research are discussed.  相似文献
