This paper deals with information needs, seeking, searching, and uses within scholarly communities by introducing theory from the field of science and technology studies. In particular it contributes to the domain-analytic approach in information science by showing that Whitley’s theory of ‘mutual dependence’ and ‘task uncertainty’ can be used as an explanatory framework in understanding similarity and difference in information practices across intellectual fields. Based on qualitative case studies of three specialist scholarly communities across the physical sciences, applied sciences, social sciences and arts and humanities, this paper extends Whitley’s theory into the realm of information communication technologies. The paper adopts a holistic approach to information practices by recognising the interrelationship between the traditions of informal and formal scientific communication and how it shapes digital outcomes across intellectual fields. The findings show that communities inhabiting fields with a high degree of ‘mutual dependence’ coupled with a low degree of ‘task uncertainty’ are adept at coordinating and controlling channels of communication and will readily co-produce field-based digital information resources, whereas communities that inhabit fields characterised by the opposite cultural configuration, a low degree of ‘mutual dependence’ coupled with a high degree of ‘task uncertainty’, are less successful in commanding control over channels of communication and are less concerned with co-producing field-based digital resources and integrating them into their epistemic and social structures. These findings have implications for the culturally sensitive development and provision of academic digital resources such as digital libraries and web-based subject portals. 相似文献

This paper examines the changes of information searchers’ topic knowledge levels in the process of completing information tasks. Multi-session tasks were used in the study, which enables the convenience of eliciting users’ topic knowledge during their process of completing the whole tasks. The study was a 3-session laboratory experiment with 24 participants, each time working on one subtask in an assigned 3-session general task. The general task was either parallel or dependently structured. Questionnaires were administered before and after each session to elicit users’ perceptions of their knowledge levels, task attributes, and other task features, for both the overall task and the sub-tasks. Our results support the assumption that users’ knowledge generally increases after each search session, but there were exceptions in which a “ceiling” effect was shown. We also found that knowledge was correlated with users’ perceptions of task attributes and accomplishment. In addition, task type was found to affect several aspects of knowledge levels and knowledge change. These findings further our understanding of users’ knowledge in information tasks and are thus helpful for information retrieval research and system design. 相似文献

To improve search engine effectiveness, we have observed an increased interest in gathering additional feedback about users’ information needs that goes beyond the queries they type in. Adaptive search engines use explicit and implicit feedback indicators to model users or search tasks. In order to create appropriate models, it is essential to understand how users interact with search engines, including the determining factors of their actions. Using eye tracking, we extend this understanding by analyzing the sequences and patterns with which users evaluate query result returned to them when using Google. We find that the query result abstracts are viewed in the order of their ranking in only about one fifth of the cases, and only an average of about three abstracts per result page are viewed at all. We also compare search behavior variability with respect to different classes of users and different classes of search tasks to reveal whether user models or task models may be greater predictors of behavior. We discover that gender and task significantly influence different kinds of search behaviors discussed here. The results are suggestive of improvements to query-based search interface designs with respect to both their use of space and workflow. 相似文献

The acquisition of information and the search interaction process is influenced strongly by a person’s use of their knowledge of the domain and the task. In this paper we show that a user’s level of domain knowledge can be inferred from their interactive search behaviors without considering the content of queries or documents. A technique is presented to model a user’s information acquisition process during search using only measurements of eye movement patterns. In a user study (n = 40) of search in the domain of genomics, a representation of the participant’s domain knowledge was constructed using self-ratings of knowledge of genomics-related terms (n = 409). Cognitive effort features associated with reading eye movement patterns were calculated for each reading instance during the search tasks. The results show correlations between the cognitive effort due to reading and an individual’s level of domain knowledge. We construct exploratory regression models that suggest it is possible to build models that can make predictions of the user’s level of knowledge based on real-time measurements of eye movement patterns during a task session. 相似文献

The goal of the study presented in this article is to investigate to what extent the classification of a web page by a single genre matches the users’ perspective. The extent of agreement on a single genre label for a web page can help understand whether there is a need for a different classification scheme that overrides the single-genre labelling. My hypothesis is that a single genre label does not account for the users’ perspective. In order to test this hypothesis, I submitted a restricted number of web pages (25 web pages) to a large number of web users (135 subjects) asking them to assign only a single genre label to each of the web pages. Users could choose from a list of 21 genre labels, or select one of the two ‘escape’ options, i.e. ‘Add a label’ and ‘I don’t know’. The rationale was to observe the level of agreement on a single genre label per web page, and draw some conclusions about the appropriateness of limiting the assignment to only a single label when doing genre classification of web pages. Results show that users largely disagree on the label to be assigned to a web page. 相似文献

This paper proposes to review and assess social scientific debate about the origins and nature of innovation in modern society. It focuses on three sub-sets of conceptualisation, critique and commentary that refer specifically to sub-national or regional innovation systems. Research in the latter field has grown enormously in recent years. Moreover, new perspectives from other disciplines than regional science have been promoted. One distinctive view of relevance in that it is focused on the role in innovation of specific ‘entrepreneurial universities’ in relation to industry and government is, of course, the ‘Triple Helix’ approach. This is reviewed and sympathetically critiqued. A second view, less sympathetically critiqued here, is one that itself attacks all so-called ‘new regionalism’ for stressing the importance of institutions, industry embeddedness and the micro-science of regional economic development. Dazzled by ‘Globalisation 1’ and the totalising power of ‘scale’ geographies, this rejection of the worth of spatial analysis at less than the global or national ‘scalar envelope’ is assessed for its potential insights into weaknesses of the regional innovation systems approach but found wanting in both technical accuracy and scholarly competence. Finally, the state of the art in regional innovation systems research is sketched by reference both to recent longitudinal findings and elaborations into specific technological fields, particularly but not only Bioregional Innovation Systems that help move us towards a newer theory of economic geography in the knowledge economy, based on ‘regional knowledge capabilities.’ The analysis conclusively proposes ‘Globalisation 2’, a ‘ground-up’ knowledge-driven evolution of the earlier ‘top-down’ multilateral trade institution and corporately driven ‘Globalisation 1.’ 相似文献

On the innovativeness of foreign affiliates: Evidence from companies in The Netherlands 总被引：1，自引：0，他引：1
In examining the distinctive contributions of foreign subsidiaries and domestic firms to innovative performance in Dutch manufacturing, the paper shows that foreign ownership is an important factor in explaining inter-firm differences affecting innovativeness. It characterizes innovativeness by distinguishing between products that are new to the firm (‘imitative’ innovations), and those products that are new to the market (‘real’ innovations). It uses firm-level data for 4780 firms which took part in the Community Innovation Survey (CIS-2) for 1996 in The Netherlands. It concludes that foreign subsidiaries are more innovative, they are more likely to introduce ‘imitative’ as well as ‘real’ innovations compared to domestic firms. In comparison with the population of innovative companies, however, there is greater heterogeneity among foreign subsidiaries, i.e. they are not more likely to introduce ‘real’ innovations if they cannot utilize knowledge transfer from an associated company. 相似文献

Research on technological partnerships has traditionally sought explanation of their high failure rates in partner characteristics and relationship features. This study introduces the notion of a ‘bumpy road’ in technology partnerships which refers to undesired outcomes such as ‘partnership mal-functioning’ and ‘instability’ to the degree to which innovation activities are hampered. We explain how firm-level strategies can reduce the probability of a ‘bumpy road’ in partnerships. We also assess the impact of this ‘bumpy road’ on innovative performance. We find that firms that excel in diversification of external activities (in terms of different types of partners) perform best. Moreover, a persistent product oriented innovation strategy geared at developing new products, new markets, or higher product quality will yield more stable partnership outcomes. Our results confirm that engagement in partnerships is beneficial for innovative performance. However, firms that experienced a ‘bumpy road’ in their technological partnerships have to pay a price in terms of a negative effect on their innovative performance. 相似文献

Rethinking the market-technology relationship for innovation 总被引：1，自引：0，他引：1

This paper revisits the ‘what causes innovation — market pull or technology push?’ debate to argue that the conceptualisation is flawed and that the firm is the only ‘agent’ capable of innovative action. The paper differentiates between ‘use’, ‘need’ and ‘intended use’ to obtain greater precision with respect to the technology-market matching process that is fundamental to innovation. The validity of the approach is demonstrated through empirical examples. These examples also show the value of distinguishing between two types of market concept used by the innovating firm. These are the ‘reference market’ which is a traded product that is a principal source of ‘use’ ideas for the mental construction of the ‘innovation market’ concept. It is the latter that can be thought to guide the construction of innovative production technology. 相似文献

This paper employs the three concepts of ‘gold’ (financial rewards), ‘ribbon’ (reputational/career rewards) and ‘puzzle’ (intrinsic satisfaction) to examine the extrinsic and intrinsic aspects of scientists’ motivation for pursuing commercial activities. The study is based on 36 individual interviews and an on-line questionnaire survey of 735 scientists from five major UK research universities. It finds that there is a diversity of motivations for commercial engagement, and that many do so for reputational and intrinsic reasons and that financial rewards play a relatively small part. The paper draws on self-determination theory in social psychology to analyse the relationship between scientists’ value orientations with regard to commercial engagement and their personal motivations. It finds that those with traditional beliefs about the separation of science from commerce are more likely to be extrinsically motivated, using commercialization as a means to obtain resources to support their quest for the ‘ribbon’. In contrast, those identify closely with entrepreneurial norms are intrinsically motivated by the autonomy and ‘puzzle-solving’ involved in applied commercial research while also motivated by the ‘gold’. The study highlights the primacy of scientists’ self-motivation, and suggests that a fuller explanation of their commercial behaviour will need to consider a broader mix of motives to include the social and affective aspects of intrinsic motivation. In conclusion, the paper argues that policy to encourage commercial engagement should build on reputational and intrinsic rather than purely financial motivations. 相似文献

This paper reports on the findings from a longitudinal case study exploring Kuhlthau’s information search process (ISP)-model in a group based academic setting. The research focus is on group members’ activities and cognitive and emotional experiences during the task process of writing an assignment. It is investigated if group members’ information behavior differ from the individual information seeker in the ISP-model and to what extent this behavior is influenced by contextual (work task) and social (group work) factors. Three groups of LIS students were followed during a 14 weeks period in 2004/2005 (10 participants). Quantitative and qualitative methods were employed, such as demographic surveys, process surveys, diaries and interviews. Similarities in behavior were found between group members and the individual in Kuhlthau’s ISP-model with regard to the general stages of information seeking, the cognitive pattern associated with focus formulation and the tendency towards an increase in writing activities while searching activities decreased. Differences in behavior were also found, which were associated with contextual and social factors beyond the mere search process. It is concluded that the ISP-model does not fully comply with group members’ problem solving process and the involved information seeking behavior. Further, complex academic problem solving seems to be even more complex when it is performed in a group based setting. The study contributes with a new conceptual understanding of students’ behavior in small groups. 相似文献

Entrepreneurship: Exploring the knowledge base 总被引：1，自引：0，他引：1
Entrepreneurship research has a long tradition and since the 1980s the field has grown significantly. In this study we identify the ‘knowledge producers’ who have shaped the field over time and their core entrepreneurship research works. A unique database consisting of all references in twelve entrepreneurship ‘handbooks’ (or state-of-the-art books) has been developed. The chapters in these handbooks were written by experts within the field, and it can be assumed that the most frequently cited references represent ‘core knowledge’ with relevance to entrepreneurship research.From our analysis, it appears that entrepreneurship is a rather changeable field of research, closely linked to disciplines such as ‘management studies’ and ‘economics’. Over time, the field has become more formalized with its own core knowledge, research specialities and an increasing number of ‘insider works’. However, it is still based on some fairly old theoretical frameworks imported from mainstream disciplines, although during the last decade we have seen the emergence of a number of new field-specific concepts and theories. We argue that to successfully develop entrepreneurship research in the future, we need to relate new research opportunities to earlier knowledge within the field, which calls for a stronger ‘knowledge-based’ focus. We would also like to see greater integration between the fields of entrepreneurship and innovation studies in the future. 相似文献

‘Lower-tech’ sectors are still commonly regarded as unusual suspects in the modern process of innovation and economic change. In this paper we try to understand better how organisations specialising in traditional businesses have been transformed by a period of paradigm-shift such as the one that characterised the final decades of the twentieth century. We focus on a population of nearly 500 of the world's largest innovative companies to assess the extent to which companies belonging to ‘old-economy’ sectors have been developing cutting-edge knowledge about clusters of new technologies such as ICT, new materials and biotechnology. We find that ‘non-high-tech’ corporations transformed their patent portfolios in a non-trivial way. Companies in mature trades contributed significantly to the development of technologies that are at the core of the so-called Third Industrial Revolution. 相似文献

This study investigated whether and how different factors in relation to task, user-perceived knowledge, search process, and system affect users’ search tactic selection. Thirty-one participants, representing the general public with their own tasks, were recruited for this study. Multiple methods were employed to collect data, including pre-questionnaire, verbal protocols, log analysis, diaries, and post-questionnaires. Statistical analysis revealed that seven factors were significantly associated with tactic selection. These factors consist of work task types, search task types, familiarity with topic, search skills, search session length, search phases, and system types. Moreover, the study also discovered, qualitatively, in what ways these factors influence the selection of search tactics. Based on the findings, the authors discuss practical implications for system design to support users’ application of multiple search tactics for each factor. 相似文献

Many user-centred studies of electronic information resources include a think-aloud element – where users are asked to verbalise their thoughts, interface actions and sometimes their feelings whilst using these resources to help them complete one or more information tasks. These studies are usually conducted with the purpose of identifying usability issues related to the resource(s) used or understanding aspects of users’ information behaviour. However, few of these studies present detailed accounts of how their think-aloud data was collected and analysed or provide detailed reflection on methodological decisions made. In this article, we discuss and reflect on the methodology used when planning and conducting a think-aloud study of lawyers’ interactive information behaviour. Our discussion is framed by Blandford et al.’s PRET A Rapporter (‘ready to report’) framework – a framework that can be used to plan, conduct and describe user-centred studies of electronic information resource use from an information work perspective. 相似文献

Professional, workplace searching is different from general searching, because it is typically limited to specific facets and targeted to a single answer. We have developed the semantic component (SC) model, which is a search feature that allows searchers to structure and specify the search to context-specific aspects of the main topic of the documents. We have tested the model in an interactive searching study with family doctors with the purpose to explore doctors’ querying behaviour, how they applied the means for specifying a search, and how these features contributed to the search outcome. In general, the doctors were capable of exploiting system features and search tactics during the searching. Most searchers produced well-structured queries that contained appropriate search facets. When searches failed it was not due to query structure or query length. Failures were mostly caused by the well-known vocabulary problem. The problem was exacerbated by using certain filters as Boolean filters. The best working queries were structured into 2–3 main facets out of 3–5 possible search facets, and expressed with terms reflecting the focal view of the search task. The findings at the same time support and extend previous results about query structure and exhaustivity showing the importance of selecting central search facets and express them from the perspective of search task. The SC model was applied in the highest performing queries except one. The findings suggest that the model might be a helpful feature to structure queries into central, appropriate facets, and in returning highly relevant documents. 相似文献

This paper presents a new approach to query expansion in search engines through the use of general non-topical terms (NTTs) and domain-specific semi-topical terms (STTs). NTTs and STTs can be used in conjunction with topical terms (TTs) to improve precision in retrieval results. In Phase I, 20 topical queries in two domains (Health and the Social Sciences) were carried out in Google and from the results of the queries, 800 pages were textually analysed. Of 1442 NTTs and STTs identified, 15% were shared between the two domains; 62% were NTTs and 38% were STTs; and approximately 64% occurred before while 36% occurred after their respective topical terms (TTs). Findings of Phase II showed that query expansion through NTTs (or STTs) particularly in the ‘exact title’ and URL search options resulted in more precise and manageable results. Statistically significant differences were found between Health and the Social Sciences vis-à-vis keyword and ‘exact phrase’ search results; however there were no significant differences in exact title and URL search results. The ratio of exact phrase, exact title, and URL search result frequencies to keyword search result frequencies also showed statistically significant differences between the two domains. Our findings suggest that web searching could be greatly enhanced combining NTTs (and STTs) with TTs in an initial query. Additionally, search results would improve if queries are restricted to the exact title or URL search options. Finally, we suggest the development and implementation of knowledge-based lists of NTTs (and STTs) by both general and specialized search engines to aid query expansion. 相似文献

Science and Technology Studies (STS) is one of a number of new research fields to emerge over the last four or five decades. This paper attempts to identify its core academic contributions from the perspective of the authors of chapters in authoritative ‘handbooks’ and the references they cite. Besides identifying the most prominent publications, institutions and authors, we examine whether the core contributions can be broken down into identifiable clusters. The study also analyses the impact of these contributions by exploring the research fields, journals, and geographical location of the researchers that have cited the STS core contributions in their own work. Together, these analyses reveal a number of phases in the development of STS with periods of convergence and divergence of the field, including the gradual separation of quantitative studies of science and technology from the main body of STS. The paper ends with some conclusions about the evolution of STS, such as the role of ‘institution builders’ in developing new research fields and the structures required to hold them together. 相似文献
