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   

Impact of combining data from multiple instruments on performance of patient-based real-time quality control

IntroductionIt is unclear what is the best strategy for applying patient-based real-time quality control (PBRTQC) algorithm in the presence of multiple instruments. This simulation study compared the error detection capability of applying PBRTQC algorithms for instruments individually and in combination using serum sodium as an example.Materials and methodsFour sets of random serum sodium measurements were generated with differing means and standard deviations to represent four simulated instruments. Moving median with winsorization was selected as the PBRTQC algorithm. The PBRTQC parameters (block size and control limits) were optimized and applied to the four simulated laboratory data sets individually and in combination.ResultsWhen the PBRTQC algorithm were individually optimized and applied to the data of the individual simulated instruments, it was able to detect bias several folds faster than when they were combined. Similarly, the individually applied algorithms had perfect error detection rates across different magnitudes of bias, whereas the error detection rates of the algorithm applied on the combined data missed smaller biases. The performance of the individually applied PBRTQC algorithm performed more consistently among the simulated instruments compared to when the data were combined.DiscussionWhile combining data from different instruments can increase the data stream and hence, increase the speed of error detection, it may widen the control limits and compromising the probability of error detection. The presence of multiple instruments in the data stream may dilute the effect of the error when it only affects a selected instrument.  相似文献

Humanities in the primary school – philosophical considerations     

Tony Eaude 《Education 3-13》2017,45(3):343-353

ABSTRACT

Drawing on a range of philosophical traditions, this article argues that the humanities are essential aspects of the development of the whole child. The humanities help children to understand themselves and other people in relation to place, time, belief, identity and culture and to become empathetic, thoughtful and critical citizens. Learning the content, language, concepts, skills and ways of working associated with separate disciplines is important, as is exploration of key ideas related to human experience and culture, including controversial ones. Defining the humanities in the primary years by the types of knowledge, qualities and values involved may be more appropriate than by subject. These can be learned, and reinforced, in all subject areas, with some offering particularly fertile opportunities, and through cross-curricular approaches. An emphasis on factual knowledge is too limiting, with active, first-hand experience helping to engage and include children. To teach and demonstrate appropriate ways of working and thinking, teachers require pedagogical content knowledge and enthusiasm as well as subject knowledge.  相似文献   

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

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   

Towards a method to disseminate knowledge from the post project review     

Davar?RezaniaEmail author  Tony?Lingham 《知识管理研究与实践》2009,7(2):172-177

In this paper we review several issues associated with post project review and dissemination of knowledge in information technology projects. We reflect on our practice of coaching project teams. In identifying the role of social pressure in forming teams’ perception of their performance, we suggest what could potentially be an interesting and fruitful avenue of future research on an approach to post project review and dissemination of knowledge in organizations.  相似文献   

Mentoring for Principals: Pre-Service and In-Service Models     

Tony Bush 《Asia Pacific Journal of Education》1995,15(1):1-13

Mentoring is an increasingly important element in the preparation of principals in many countries, including Singapore, the United States (US) and the United Kingdom (UK). In Singapore and the US, mentoring forms part of a pre-service programme of training for intending principals. In the UK, it is a voluntary programme which takes place during their first year as principals. The efficacy of mentoring depends on the quality of the mentor/protege relationship at least as much as the organisational and cultural framework within which it operates. Definitions and conceptions of mentoring are remarkably similar in different societies and its advantages appear to outweigh its disadvantages in both Singapore and the UK.  相似文献   

NEW TECHNOLOGY FOR HOME‐BASED LEARNING: THE CHALLENGE TO CAMPUS‐BASED INSTITUTIONS     

Tony Bates 《Learning, Media and Technology》1978,4(2):4-13

Although there may be little expansion for conventional higher education on campus in the next decade, there is an unmet and growing need to provide home‐based continuing education. This will require an effective means of delivering learning materials to homes on a greater scale than can be handled by broadcasting alone, as well as the production of high quality software appropriate both to the means of delivery and the needs of students. There are several developments in technology which hold out promise for home use; these need to be developed as part of a wider learning system. Campus‐based institutions are well placed both to develop the hardware and to produce suitable learning materials, but this means that higher education institutions must show a much more flexible attitude to continuing education and to co‐operation with other organisations.  相似文献
