The study of information systems and their influence on organisational culture is a complex and highly contested area of research which has been the subject of much theorising. This paper intends to add to the debate through a longitudinal case study of an integrated information system implementation undertaken within a large UK university. The system known as SITS (Strategic Information Technology Services) was introduced into the university in 2006 and the focus of the research has been on culture change within the SITS environment. Document analysis, interviews and participant observation were used to collect the data for this study. What has emerged from this study is that current approaches are unable to account for the complexity of cultural studies within an integrated information systems environment and therefore we have developed the concept of the ‘cultural kaleidoscope’ as a heuristic to better understand the nature of cultural change within these circumstances. 相似文献

This research investigates the motivational aspects of information management practice by developing and performing an initial test of the theorization on the components and structural properties of a new variable, called information management motivation (IMM). Based on a synthesis of the motivation and information processing literature in the information systems, psychology, management, and information technology training fields, we theorize IMM as a second order construct composed of formative sub-constructs of proactiveness, sharing, transparency, and formality. New measures were developed for the constituent constructs of IMM and refined through two studies involving 120 knowledge workers. The model of IMM was tested, confirming the proposed structural relationships between the constituent constructs and IMM. The study findings provide important insights on understanding and improving individual knowledge workers’ information management activities. 相似文献

Websites play a critical role in attracting customers and providing information to assist Web customers in decision making. Despite the importance of such systems providing a satisfactory experience, as per our knowledge no effort has been made to systematically examine the underlying causal structure among important decision related variables such as perceived effort, perceived information accuracy, perceived effectiveness, and satisfaction using Web-based decision support systems (Web-based DSS) that provide information to potential customers. In this study, we develop a conceptual model for investigating cognitive antecedents to Web users’ satisfaction in the context of Web-based DSS. The empirical examination of the research model using structural equations modeling indicates that perceived effectiveness is influenced by perceived information accuracy and effort, and in turn, has positive impact on satisfaction in using Web-based DSS. The implications of this study suggest to information managers that providing customers with highly accurate information from web sites requiring lower effort is perceived as an effective system and such perception leads to increased satisfaction. 相似文献

A recommender system has an obvious appeal in an environment where the amount of on-line information vastly outstrips any individual’s capability to survey. Music recommendation is considered a popular application area. In order to make personalized recommendations, many collaborative music recommender systems (CMRS) focus on capturing precise similarities among users or items based on user historical ratings. Despite the valuable information from audio features of music itself, however, few studies have investigated how to utilize information extracted directly from music for personalized recommendation in CMRS. In this paper, we describe a CMRS based on our proposed item-based probabilistic model, where items are classified into groups and predictions are made for users considering the Gaussian distribution of user ratings. In addition, this model has been extended for improved recommendation performance by utilizing audio features that help alleviate three well-known problems associated with data sparseness in collaborative recommender systems: user bias, non-association, and cold start problems in capturing accurate similarities among items. Experimental results based on two real-world data sets lead us to believe that content information is crucial in achieving better personalized recommendation beyond user ratings. We further show how primitive audio features can be combined into aggregate features for the proposed CRMS and analyze their influences on recommendation performance. Although this model was developed originally for music collaborative recommendation based on audio features, our experiment with the movie data set demonstrates that it can be applied to other domains. 相似文献

This paper reviews the application of computer-based information systems for manufacturing, which has found a lack of strategic orientation. Critical factors for a strategic-oriented information system, i.e. external information scanning, data refining and information reporting, are discussed. A strategic-oriented system model that incorporates information scanning-refining-reporting into manufacturing automation and control systems is proposed. A case study of a corporate strategic information processing system in a UK company is explored. Limitations of the study and suggestions for future research are made. 相似文献

Using technology to facilitate learning in universities and other higher education institutions (HEIs) has become common practice due to its ability to reduce barriers related to time and space in traditional learning environments. However, current literature mostly focuses on the use of the technology and not on the use of the information it conveys. Also, very few studies focus on technology adoption in universities and HEIs in developing countries, especially those in Africa. Thus, we propose a model that explains the changing information behaviors of students in this digital age and the effect this has on their learning outcomes. We collected questionnaire data from 303 students and analyzed the data using structural equation modelling partial least squares (SEM-PLS). We found that our proposed model explains 60.2 % of student satisfaction, 24.2 % of academic performance, 24.1 % of information sharing, and 19.8 % of their information exchange behavior. This study confirms that the use of digital information and its antecedent factors have significant effects on the college experience of students. This has several implications for information systems research and practice, especially in the design and assessment of technology use in learning environments. 相似文献

The concept of information is clearly foundational to the ‘information’ disciplines but lacking in a clear conceptual foundation. In this paper we propose that the concept is clearly overloaded and suggest that a new vocabulary is needed to enhance our powers of understanding and explanation. We argue that information is better situated at the intersection of signs, patterns and systems, which involves the enactment of forma (the substance of a sign), informa (the content of a sign) and performa (the use of signs in coordinated action). Within this perspective ‘information’ is considered an accomplishment not only of humans but also of animals. This leads us to use a well-documented case from the animal kingdom, that of communication amongst Gunnison prairie dogs, to both ground and expand upon significant elements from our conceptual framework. This we believe helps shed new light on what the juxtaposition of information with behaviour actually means. 相似文献

Current awareness services are designed to keep users informed about recent developments based around user need profiles. In organisational settings, they may operate through both electronic and social interactions aimed at delivering information that is relevant, pertinent and current. Understanding these interactions can reveal the tensions in current awareness dissemination and help inform ways of making services more effective and efficient. We report an in-depth, observational study of electronic current awareness use within a large London law firm. The study found that selection, re-aggregation and forwarding of information by multiple actors gives rise to a complex sociotechnical distribution network. Knowledge management staff act as a layer of “intelligent filters” sensitive to complex, local information needs; their distribution decisions address multiple situational relevance factors in a situation fraught with information overload and restrictive time-pressures. Their decisions aim to optimise conflicting constraints of recall, precision and information quantity. Critical to this is the use of dynamic profile updates which propagate back through the network through formal and informal social interactions. This supports changes to situational relevance judgements and so allows the network to ‘self-tune’. These findings lead to design requirements, including that systems should support rapid assessment of information items against an individual’s interests; that it should be possible to organise information for different subsequent uses; and that there should be back-propagation from information consumers to providers, to tune the understanding of their information needs. 相似文献

In this paper, we present the state of the art in the field of information retrieval that is relevant for understanding how to design information retrieval systems for children. We describe basic theories of human development to explain the specifics of young users, i.e., their cognitive skills, fine motor skills, knowledge, memory and emotional states in so far as they differ from those of adults. We derive the implications these differences have on the design of information retrieval systems for children. Furthermore, we summarize the main findings about children’s search behavior from multiple user studies. These findings are important to understand children’s information needs, their search strategies and usage of information retrieval systems. We also identify several weaknesses of previous user studies about children’s information-seeking behavior. Guided by the findings of these user studies, we describe challenges for the design of information retrieval systems for young users. We give an overview of algorithms and user interface concepts. We also describe existing information retrieval systems for children, in specific web search engines and digital libraries. We conclude with a discussion of open issues and directions for further research. The survey provided in this paper is important both for designers of information retrieval systems for young users as well as for researchers who start working in this field. 相似文献

Scientists continually work with information to move their research projects forward, but the activities involved in finding and using information and their impact on discovery are poorly understood. In the Information and Discovery in Neuroscience (IDN) project we investigated the information work involved as researchers make progress and confront problems in the practice of brain research. Through case studies of recent neuroscience projects, we found that the most difficult and time-consuming information activities had parallels with Simon’s explication of weak methods in scientific problem solving. But, while Simon’s weak/strong distinction is an effective device for interpreting information work, his general conception of how discovery takes place is artificially constrained. We present cross-case and case-based results from the IDN project to illustrate how the conditions of problem solving Simon associated with weak methods relate to information work and to identify additional weak aspects of the research process not considered by Simon. Our analysis both extends Simon’s framework of what constitutes the discovery process and further elaborates how weak approaches influence the conduct of research. 相似文献

Organisations increasingly realise that they must transform into true digital enterprises to create competitive advantage and ensure corporate survival. However, many organisations do not realise that successful digital transformation (DT) requires much more than technology; it can only succeed if they manage their data, information and knowledge as true business assets. This paper describes collaborative research conducted by academic and industry partners, a mutually beneficial journey spanning the past ten years. The aim was to develop a Holistic Information Asset Management (HIAM) model indicating the important areas of information asset management (IAM) that support the DT journey. Interviews were conducted with C-level executives in organisations from all industries on three continents to investigate their IAM practices, the barriers to good IAM and the benefits of managing information assets (IAs) well. This paper proposes that organisations should focus on ten domains in their quest for effective IAM: i) business benefits, ii) business environment, iii) executive awareness, iv) leadership and management, v) information environment, vi) information systems, vii) information behaviour, viii) information attributes/quality, ix) information performance and x) justification. 相似文献

The COVID-19 pandemic has forced many organisations to undergo significant transformation, rethinking key elements of their business processes and use of technology to maintain operations whilst adhering to a changing landscape of guidelines and new procedures. This study offers a collective insight to many of the key issues and underlying complexities affecting organisations and society from COVID-19, through an information systems and technological perspective. The views of 12 invited subject experts are collated and analysed where each articulate their individual perspectives relating to: online learning, digital strategy, artificial intelligence, information management, social interaction, cyber security, big data, blockchain, privacy, mobile technology and strategy through the lens of the current crisis and impact on these specific areas. The expert perspectives offer timely insight to the range of topics, identifying key issues and recommendations for theory and practice. 相似文献

Information technology (IT) has transformed business practices in the last several decades: operations, product strategies, distribution, and customer service have become increasingly dependent on IT. Moreover, IT has changed its orientation from that of pure operational utility in the 1960s and 1970s to that of a competitive weapon in the 1990s and today. These phenomena have affected the way modern organizations are managed, as well as the way IT affects the strategic activities of an organization's value-chain.In particular, aligning an organization's business and IT strategies in order to deliver higher business performance presupposes a strategic business opportunity to which information systems technology is integral. In other words, Strategic Alignment between business and IT can have a positive business impact only if we see an organization's IT components as parts of a well-integrated organizational system. If business strategy is viewed separately from IT strategy or IT strategy is viewed only as a “support” tool, then there is little likelihood that the above positive impact of strategic alignment can take place.This research suggests, develops and tests a strategic co-alignment model by examining three types of integration that impact the planning process and the overall performance of information-intensive organizations: technological integration (TI), functional integration and strategic integration (SI).The results of this research yield some useful set of guidelines for theory building for IS, as well as for the business practice aspect of IS: most interesting is the role of consistency (co-alignment) between an organization's business and strategic information systems plans to improve overall firm performance. Other recommendations include having a high degree of involvement of IS executives in corporate planning, the use of outsourcing services to promote organizational systems integration, and the importance of internal coordination mechanisms to facilitate both systems consistency and lower transaction costs. Finally, this study has employed cluster analysis and discriminant analysis to interpret the research findings. 相似文献

The ability to internationalize has become a competitive necessity for many SMEs, enabling their survival and access to larger markets. From an IS research perspective, one important issue is the strategic role played by the firm's IT capabilities in responding to greater environmental uncertainty and correspondingly greater information requirements, and in enabling the firm's internationalization performance. Given that such a major aspect of the influence of IT on the performance of SMEs has so far been ignored, the following research question is posed: to what extent does the match between the IT capabilities and information requirements of SMEs contribute to their internationalization performance? Our research model and hypotheses are based on Tushman and Nadler's information processing model. In revisiting this model, the aim was to show its continued relevancy and extend its domain of applicability. In order to answer the research question, we conduct a survey-based empirical study of 174 Canadian SMEs that have internationalized their activities. Our results show that a better match between IT capabilities and information requirements does indeed exert a positive influence on internationalization performance. We also find that the SMEs’ IT capabilities are influenced externally by the environmental uncertainty and internally by their internationalization mode. 相似文献

A perspective is presented to bring into focus the state-of-the-art and development of methods and criteria which relate to the problem of design and performance evaluation of information systems. Two major aspects of design and evaluation are considered. These are the initiation, planning, development and testing of new information systems, to include modification of existing structures; and the appraisals and measurement of operational systems and their components. A taxonomy of information systems is presented in order to provide for a basis of organized evaluation of system performance. 相似文献

The thesis of this study is to propose an extended methodology for laboratory based Information Retrieval evaluation under incomplete relevance assessments. This new methodology aims to identify potential uncertainty during system comparison that may result from incompleteness. The adoption of this methodology is advantageous, because the detection of epistemic uncertainty – the amount of knowledge (or ignorance) we have about the estimate of a system’s performance – during the evaluation process can guide and direct researchers when evaluating new systems over existing and future test collections. Across a series of experiments we demonstrate how this methodology can lead towards a finer grained analysis of systems. In particular, we show through experimentation how the current practice in Information Retrieval evaluation of using a measurement depth larger than the pooling depth increases uncertainty during system comparison. 相似文献
