Information retrieval in the workplace: A comparison of professional search practices     

Tony Russell-Rose  Jon Chamberlain  Leif Azzopardi 《Information processing & management》2018,54(6):1042-1057

Legal researchers, recruitment professionals, healthcare information professionals, and patent analysts all undertake work tasks where search forms a core part of their duties. In these instances, the search task is often complex and time-consuming and requires specialist expertise to identify relevant documents and insights within large domain-specific repositories and collections. Several studies have been made investigating the search practices of professionals such as these, but few have attempted to directly compare their professional practices and so it remains unclear to what extent insights and approaches from one domain can be applied to another. In this paper we describe the results of a survey of a purposive sample of 108 legal researchers, 64 recruitment professionals and 107 healthcare information professionals. Their responses are compared with results from a previous survey of 81 patent analysts. The survey investigated their search practices and preferences, the types of functionality they value, and their requirements for future information retrieval systems. The results reveal that these professions share many fundamental needs and face similar challenges. In particular a continuing preference to formulate queries as Boolean expressions, the need to manage, organise and re-use search strategies and results and an ambivalence toward the use of relevance ranking. The results stress the importance of recall and coverage for the healthcare and patent professionals, while precision and recency were more important to the legal and recruitment professionals. The results also highlight the need to ensure that search systems give confidence to the professional searcher and so trust, explainability and accountability remains a significant challenge when developing such systems. The findings suggest that translational research between the different areas could benefit professionals across domains.  相似文献

From peripheral to full participation in a blended trade bargaining simulation     

Tony Carr  lenda Cox  ndrea Eden  Monique Hanslo 《British journal of educational technology : journal of the Council for Educational Technology》2004,35(2):197-211

This article considers the extent and nature of student participation in a trade bargaining simulation from a community of practice perspective. This third‐year economics module included a blend of online communication (through email, online chats and online discussions) and face‐to‐face meetings, both in smaller bargaining groups and in whole class plenary meetings. Our method of analysis includes the use of Exchange Structure Analysis of text chats and face‐to‐face learning conversations, triangulated by observation, survey and interview data. The focus on community of practice enables us to offer a nuanced interpretation of differences in crude participation data derived from the online chats. Superficially, the data may suggest marginalisation of participants, but Wenger's (1988 ) notion of peripheral participation with a trajectory towards full participation reframes the disparities in terms of an active community of practice. Some members are fully engaged with the practices of trade bargaining from the early stages of the simulation, while others move towards full participation over the duration of the simulation. Our results suggest that the laboratory‐based online text chats did provide opportunities for student participation in the simulation, and that male and female students exhibited different patterns of participation in the chats.  相似文献

Testing Measurement Invariance Across Unobserved Groups: The Role of Covariates in Factor Mixture Modeling     

Yan Wang  Eunsook Kim  John M. Ferron  Robert F. Dedrick  Tony X. Tan  Stephen Stark 《Educational and psychological measurement》2021,81(1):61

Factor mixture modeling (FMM) has been increasingly used to investigate unobserved population heterogeneity. This study examined the issue of covariate effects with FMM in the context of measurement invariance testing. Specifically, the impact of excluding and misspecifying covariate effects on measurement invariance testing and class enumeration was investigated via Monte Carlo simulations. Data were generated based on FMM models with (1) a zero covariate effect, (2) a covariate effect on the latent class variable, and (3) covariate effects on both the latent class variable and the factor. For each population model, different analysis models that excluded or misspecified covariate effects were fitted. Results highlighted the importance of including proper covariates in measurement invariance testing and evidenced the utility of a model comparison approach in searching for the correct specification of covariate effects and the level of measurement invariance. This approach was demonstrated using an empirical data set. Implications for methodological and applied research are discussed.  相似文献

Young People's Conceptions of Environment: A phenomenographic analysis     

Tony Loughland  Anna Reid  Peter Petocz 《Environmental Education Research》2002,8(2):187-197

Environmental education in schools is an important strategy in achieving environmental improvement. However, it needs to be based on children's understandings of environment rather than on assumptions of what children know and believe. This paper reports on a research project where school children's answers to a question 'I think the term/word environment means ' were analysed using the qualitative research method of phenomenography. Six distinct conceptions were isolated, ranging from the least sophisticated--environment as a place--to the most inclusive and expansive--environment and people in a relationship of mutual sustainability. An important qualitative difference was found between conceptions that treat the environment as an object and relational conceptions. The implications of these findings for environmental education are discussed.  相似文献   

Revisiting emancipatory teacher research: a psychoanalytic perspective   总被引：1，自引：0，他引：1  

Tony Brown 《British Journal of Sociology of Education》2004,25(1):67-79

This paper addresses the issue of how human beings construct themselves as subjects and the parameters within which this is achieved. We question models in which idealism shapes the trajectory of identity formation and consider how identity might be seen alternatively as a somewhat awkward amalgam of identifications with diverse discursive domains. The particular focus is on teachers conducting ‘emancipatory’ practitioner research and on how the researcher understands his/her interface with the situation he/she is researching. We survey a range of theoretical models as offered by some leading writers, with particular reference to Jacques Lacan, and consider each in relation to how the teacher researcher might be understood. We provide as an example an account of one teacher researcher examining issues of ethnicity and gender in her secondary school French classes.  相似文献
