Although investors in financial markets have access to information from both mass media and social media, trading platforms that curate and provide this information have little to go by in terms of understanding the difference between these two types of media. This paper compares social media with mass media in the stock market, focusing on information coverage diversity and predictive value with respect to future stock absolute returns. Based on a study of nearly a million stock-related news articles from the Sina Finance news platform and 12.7 million stock-related social media messages from the popular Weibo platform in China, we find that social media covers less stocks than mass media, and this effect is amplified as the volume of media information increases. We find that there is some short-term predictive value from these sources, but they are different. Although mass media information coverage is more predictive than social media information coverage in a one-day horizon, it is the other way around in a two-to five-day horizon. These empirical results suggest that social media and mass media serve stock market investors differently. We draw connections to theories related to how crowds and experts differ and offer practical implications for the design of media-related IS systems.  相似文献

This paper reviews the institutional and cognitive profile of the information systems (IS) field in Europe, using the results of a survey of IS academics in 18 European countries. The emerging picture suggests that the study of IS in European academia is dispersed in small units with various names, which are hosted in various disciplines across the science/social science spectrum. Our survey confirms the widespread view that the IS field is concerned with the study of a wide range of themes, from developing technologies per se, to assessing the social impact of new information and communication technologies. Moreover, a variety of research perspectives and approaches is found to be pursued, drawing from both the positivist and interpretative epistemological traditions. Reflecting upon the survey findings, we argue that while the institutional dispersion is a weakness that requires remedying action, the cognitive diversity should not be considered as a characteristic of immaturity. In Europe, the diversity of themes and research perspectives probably manifests more fundamental differences of the socioeconomic context which gives rise to, and sustains, different types of IS research in different countries.  相似文献

While there is an increasing flow of media stories reporting cases of cyberbullying, particularly within online social media, research efforts in the academic community are scattered over different topics across the social science and computer science academic disciplines. In this work, we explored research pertaining to cyberbullying, conducted across disciplines. We mainly sought to understand scholarly activity on intelligence techniques for the detection of cyberbullying when it occurs. Our findings suggest that the vast majority of academic contributions on cyberbullying focus on understanding the phenomenon, risk factors, and threats, with the prospect of suggesting possible protection strategies. There is less work on intelligence techniques for the detection of cyberbullying when it occurs, while currently deployed algorithms seem to detect the problem only up to some degree of success. The article summarises the current trends aiming to encourage discussion and research with a new scope; we call for more research tackling the problem by leveraging statistical models and computational mechanisms geared to detect, intervene, and prevent cyberbullying. Coupling intelligence techniques with specific web technology problems can help combat this social menace. We argue that a multidisciplinary approach is needed, with expertise from human–computer interaction, psychology, computer science, and sociology, for current challenges to be addressed and significant progress to be made.  相似文献

This study examines the intention of environmentally-oriented social enterprises to continue using Green IS (an eco-localization website here) in Herefordshire located in the West Midlands region of the United Kingdom. The Herefordshire Greenlinks (HGL) Association is a local business community that operates primarily through the HGL Website in order to help local social enterprises find and trade local eco-friendly goods and services. It is an example of a “market-based” approach to solving social and environmental issues that is inspired by a bottom-up view of community development and eco-localization. Based on the theory of uses and gratification of media use and the new environmental paradigm, we propose a research model that outlines the various factors contributing to intention to continue using an eco-localization website. The research model and its associated hypotheses were empirically tested using a dataset generated from a survey of 83 small social enterprises. The results demonstrate the importance of three different types of gratification – content, social and performance gratification as well as users’ environmental concerns in determining the intention to continue using an eco-localization website. This study contributes to the Green IS literature by extending research to the social sector environment, and it also provides practical insight for designers of such community-led eco-localization websites.  相似文献

Technology acceptance research has shown that trust is an important factor fostering use of information systems (IS). As a result, numerous IS researchers have studied factors that build trust in IS. However, IS research on trust has mainly focused on the trust relationship between the user and the IS itself, largely neglecting that other targets of trust might also drive IS use from a user’s point of view. Accordingly, we investigate the importance of different targets of trust in IS use. Therefore, we use the concept of a network of trust and identify four different targets of trust that are prevalent from a user’s point of view. Afterwards, we develop our research model and evaluate it using a free simulation experiment. The results show that multiple targets of trust are important in the context of IS use. In particular, we highlight the importance of a second target – trust in the provider – which is equally important as trust in the IS itself. Consequently, IS providers should focus not only on fostering users’ trust in their IS but also on positioning themselves as trustworthy providers. In addition, we show that a third target – trust in the Internet – has significant indirect effects on multiple constructs that impact IS use.  相似文献

Managing information systems (IS) projects requires what we refer to as ‘control ambidexterity’, which is the use of different types of control to meet conflicting demands. This leads to the use of contrasting styles of IS project management and creates tensions in managerial practice, neither of which are well understood. We address this theoretical gap in our understanding based on an exploratory case study of an IS implementation project in the financial services industry. Adopting the lens of management styles as a meta-theoretical perspective, we sought to address two research questions: (1) Which management style(s) do IS project managers draw upon in practice and why? (2) What kinds of tensions result for IS project managers and team members from drawing upon contrasting management styles in combination – and how do IS project managers and team members deal with these tensions? Two contrasting styles of management emerged from our data – bureaucratic and collaborative – that are drawn upon by IS project managers to achieve control ambidexterity. Furthermore, drawing upon these two different styles in combination within the confines of a single project creates tensions. We explore these tensions and present an illustrative example of how IS project managers can deal with these tensions successfully in practice. Specifically, we find that they can be dealt with effectively by a tandem of two project managers who share responsibility for managing the IS project. The findings of this study have important implications for our understanding of control ambidexterity in IS projects.  相似文献

“Wisdom” has been at the heart of practical, philosophical, and spiritual disciplines since antiquity and is now increasingly receiving organizational as well as academic attention in scholarly areas that include psychology and organizational studies among others. However, practical wisdom has not received adequate focus in the information systems (IS) discipline. In this commentary, we make the case for a systemic focus on the role of wisdom in IS research, teaching, and practice. We introduce underlying theoretical concepts of wisdom; review relevant key research linking wisdom and IS; propose a framework to link wisdom with IS research, practice, and education; and discuss the implications of the framework and illustrate how it can be used to generate research opportunities for IS. We conclude that wisdom, whose goal is the common good, can provide a foundation to discover, view, understand, and resolve myriad issues that lie at the nexus of wisdom and information technologies.  相似文献

A significant recent technological development concerns the automation of knowledge and service work as a result of advances in Artificial Intelligence (AI) and its sub-fields. We use the term Intelligent Automation to describe this phenomenon. This development presents organisations with a new strategic opportunity to increase business value. However, academic research contributions that examine these developments are spread across a wide range of scholarly disciplines resulting in a lack of consensus regarding key findings and implications. We conduct the first interdisciplinary literature review that systematically characterises the intellectual state and development of Intelligent Automation technologies in the knowledge and service sectors. Based on this review, we provide three significant contributions. First, we conceptualise Intelligent Automation and its associated technologies. Second, we provide a business value-based model of Intelligent Automation for knowledge and service work and identify twelve research gaps that hinder a complete understanding of the business value realisation process. Third, we provide a research agenda to address these gaps.  相似文献

Abstract. The objectives of the research were to identify factors enabling or inhibiting the adoption and use of information systems and technology (IS/IT) in Portuguese manufacturing small and medium‐sized enterprises (SMEs) and understand how these factors interrelate in determining relative success in the adoption and use of IS/IT. This research elicited factors from previous quantitative and qualitative research, which had been shown to influence IS/IT adoption in SMEs in other contexts. A strategic change framework was used to structure the factors and ensure that comprehensive evidence about their nature and effects could be obtained in the empirical research. Further factors were identified by initial fieldwork, before carrying out 12 in‐depth case studies, across a range of situations – different industries, different levels of adoption and a range of degrees of success in IS/IT use. The pattern that emerged from the analysis of the data shows that certain factor combinations and relationships appear to determine the relative degrees of IS/IT success across the firms. This pattern can also be explained by interpreting the roles and relationships of the key actors involved in the process of IS/IT adoption and use. Top management perspectives and attitudes towards IS/IT adoption and use play an important role in the development of internal IS/IT competencies and provide an important contribution to the development of a context that enables IS/IT success.  相似文献

A well-designed field trip can promote active learning and reinforce classroom materials. Few studies have examined the potential for social media to enhance IS field trip experiences by promoting active and collaborative learning. One major barrier to the exploitation of this potential is the lack of the adoption of social media by students as a learning tool to enhance field trip experiences. Therefore, the first task is to understand how to increase the satisfaction of students in their use of social media to enhance IS field trips. This research sets out to understand the factors that could help increase students’ satisfaction with the use of social media to enhance IS field trips, and thereby their intentions to continue to use social media in future field trips. The results show that to increase user satisfaction, course instructors should ensure that students perceive the social media sites used for enhancing field trip study to be trustworthy, effortless, useful and accepted by their peers. Future research could determine how we can incorporate the use of social media to enhance the field trip learning experience.  相似文献

Scale adaptation, where authors alter the wording of an already published scale, is a deeply rooted social practice in IS research. This paper argues that the time is ripe to question this activity as well as the beliefs that have progressively formed around it. We identify and challenge five fallacious scale adaptation beliefs that hinder the development of more robust measure development norms. Contributing to this area of research, this paper offers a conceptual definition of the cognitive validity concept, defined as the extent to which a scale is free of problematic item characteristics (PICs) that bias the survey response process and subsequent empirical results. Building on this conceptualization effort, a new methodological process for assessing the cognitive validity of adapted IS measures is introduced. Through a series of three programmatic studies, we find converging evidence that the method can benefit the IS field by making the scale adaptation process more robust, transparent, and consistent. Along with the method, we introduce a new index that IS scholars can use to benchmark the cognitive quality of their scales against venerable IS measures. We discuss the implications of our work for IS research (including detailed implementation guidelines) and provide directions for future research on measurement in IS.  相似文献

This review discusses the challenges associated with the sustainability of remote workplaces, which have become more prevalent due to the growing trend of work digitalization and the pandemic-induced push to remote work. These challenges are highlighted in literature across various disciplines, including information systems, but these discourses have remained isolated from each other. In this review, we consolidated and synthesized research on remote work from the perspective of individual workers by reviewing 187 articles published between 1999 and 2020 in recognized academic journals from fields including information systems, organizational studies, economics, human resources, sociology, and psychology. We identified five key themes that concern opportunities and challenges to sustainable remote workplaces: (1) key characteristics, (2) work-life boundaries; (3) health and well-being; (4) social interaction, and (5) leadership. Building on our findings we created a framework that recognizes two interrelated categories of factors influencing remote workplace sustainability – rigid base characteristics and contextual remote workplace variables – that together shape the trajectory of remote workplace sustainability in the long term. The framework also identifies the potential role of information systems in modulating the impact of the base characteristics to build continuities that encourage more sustainable remote workplaces. The paper concludes by offering a research agenda for information systems for sustainable remote workplaces based on the three IS theoretical frames: inclusion, dignity, and boundary objects.  相似文献

Various studies show that social media is used in emergencies – and that in spite of possible challenges for emergency services, beneficial use cases can be identified. However, relatively little empirical data is available regarding the attitudes of emergency services towards social media, and almost none of a comparative nature. This article summarizes the findings of a survey conducted of the EU project ‘EmerGent’ with 761 emergency service staff across 32 European countries from September to December 2014. The main aims of the survey were to explore the attitudes expressed by emergency service staff towards social media for private and organizational use as well as the levels and main factors influencing the current and likely future use of social media in their organizations. Based on our results, we discuss possible enhancements of the emergency management cycle using social media.  相似文献

This paper aims to shed light on the dynamics of information systems (IS) as a discipline in the making. We use the ideas of the sociologist Abbott to propose three different stages of a discipline's development: differentiation, competition, and absorption. These stages reflect how disciplines go through different cycles and how they acquire, consolidate or lose elements of knowledge. We map these stages using citation and co-citation analyses of two main IS academic journals (EJIS and MISQ) from 1995 to 2008. Our results indicate that IS is currently in a stage of absorption, with research being consolidated around the theme of ‘IS acceptance’. Dominant models and frameworks related to this theme are predictive and thus lend themselves usable for positivistic and quantitative research. In this stage there is also a healthy degree of variety in IS including dormant elements which could reignite. Implications derived from our findings aim to help in the consolidation and extension of knowledge about IS in both academia and practice.  相似文献

Research across different disciplines provides enormous potential for creativity and innovation. To exploit these vast innovation opportunities, technology transfer becomes pivotal. However, yet little is known about technology transfer in interdisciplinary settings. Thus, this paper focuses on the bioeconomy, an emerging area where innovation is triggered by the combination of knowledge rooted in different disciplines. Given the potential of the bioeconomy to address the major challenges of the twenty‐first century, understanding technology transfer in this interdisciplinary research setting is of key importance. In this context, this paper explores the effectiveness of technology transfer in the interdisciplinary research setting of the bioeconomy. Empirical evidence is gathered from eight comprehensive case studies to understand how these interdisciplinary institutions manage technology transfer. We contribute to the existing body of literature by extending Bozeman's “Contingent Effectiveness Model of Technology Transfer”. Specifically, we include the increasing attention being paid to interdisciplinary collaborations. Finally, we derive managerial recommendations to improve the effectiveness of technology transfer in interdisciplinary settings.  相似文献

Social enterprises (SE) have developed various innovative business models to accomplish both social and business values for years. Not few SE’s persons have observed some critical and urgent social issues as well as human problems, but just few SE’s social media or crowdsourcing services can be provided people an efficient way to interact for these social problems. Thus, the research is to solve the need which is an integrative platform of social media and crowdsourcing service to support business innovation of social enterprise. Such a SE-specific crowdsourcing social network service (SNS) facilitate people can obtain the shared resources to further achieve the projects (i.e, volunteer activities) or even start up an innovative SE (i.e., lumni, 20%+, The Big Issue). In order to achieve SE’s charitable objective, this research is to propose and design an integration of social network and crowdsourcing service – HIVE that can provide people to post ideas, share resources, or even attend the crowdsourcing projects by the different resources. Thus, HIVE can give users to seek business opportunities, collect, connect, and users’ data analysis for social and human resources. HIVE even can provide several ways to facilitate human and resource corporations to support SE’s business innovation based on six pre-defined areas of SE and deal with the critical matching process.  相似文献

Social media has emerged over the last decade and consequently has accompanying information systems (IS) research. In this paper, however, we argue that researchers cannot keep pace with the rapid changes this topic engenders. This claim is substantiated by a database built from 28,283 articles published in either top IS journals, i.e., ELMA, BISE, and all AIS basket journals, or IS conference proceedings, i.e., ICIS, ECIS, AMCIS, WI, HICSS, and PACIS. We derive a set of 13 keywords that have been used to describe what we call the ‘social media phenomenon’. The results are transformed into a four-phase model and a taxonomical categorization, which provides an exhaustive overview of social media terms and trends and reflects the main research issue facing academia: The fact that the versatile social media phenomenon in its current phase is dominated by just two terms—“social media” and “social network”—or imprecise “such-as-Facebook” analogies.  相似文献
