A generic lexical URL segmentation framework for counting links,colinks or URLs     

Mike Thelwall  David Wilkinson 《Library & information science research》2008

Large sets of Web page links, colinks, or URLs sometimes need to be counted or otherwise summarized by researchers to analyze Web growth or publishing. Computing professionals also use them to evaluate Web sites or optimize search engines. Despite the apparently simple nature of these types of data, many different summarization methods have been used in the past. Some of these methods may not have been optimal. This article proposes a generic lexical framework to unify and extend existing methods through abstract notions of link lists and URL lists. The approach is built upon decomposing URLs by lexical segments, such as domain names, and systematically characterizing the counting options available. In addition, counting method choice recommendations are inferred from a very general set of theoretical research assumptions. The article also offers practical advice for analyzing raw data from search engines.  相似文献

Test-retest stability of the Task and Ego Orientation Questionnaire     

Lane AM  Nevill AM  Bowes N  Fox KR 《Research quarterly for exercise and sport》2005,76(3):339-346

Establishing stability, defined as observing minimal measurement error in a test-retest assessment, is vital to validating psychometric tools. Correlational methods, such as Pearson product-moment, intraclass, and kappa are tests of association or consistency, whereas stability or reproducibility (regarded here as synonymous) assesses the agreement between test-retest scores. Indexes of reproducibility using the Task and Ego Orientation in Sport Questionnaire (TEOSQ; Duda & Nicholls, 1992) were investigated using correlational (Pearson product-moment, intraclass, and kappa) methods, repeated measures multivariate analysis of variance, and calculating the proportion of agreement within a referent value of +/-1 as suggested by Nevill, Lane, Kilgour, Bowes, and Whyte (2001). Two hundred thirteen soccer players completed the TEOSQ on two occasions, 1 week apart. Correlation analyses indicated a stronger test-retest correlation for the Ego subscale than the Task subscale. Multivariate analysis of variance indicated stability for ego items but with significant increases in four task items. The proportion of test-retest agreement scores indicated that all ego items reported relatively poor stability statistics with test-retest scores within a range of +/-1, ranging from 82.7-86.9%. By contrast, all task items showed test-retest difference scores ranging from 92.5-99%, although further analysis indicated that four task subscale items increased significantly. Findings illustrated that correlational methods (Pearson product-moment, intraclass, and kappa) are influenced by the range in scores, and calculating the proportion of agreement of test-retest differences with a referent value of +/-1 could provide additional insight into the stability of the questionnaire. It is suggested that the item-by-item proportion of agreement method proposed by Nevill et al. (2001) should be used to supplement existing methods and could be especially helpful in identifying rogue items in the initial stages of psychometric questionnaire validation.  相似文献

Stability of psychometric questionnaires     

Nevill AM  Lane AM  Kilgour LJ  Bowes N  Whyte GP 《Journal of sports sciences》2001,19(4):273-278

In 1999, Wilson and Batterham proposed a new approach to assessing the test-retest stability of psychometric questionnaires. They recommended assessing the proportion of agreement - that is, the proportion of participants that record the same response to an item - using a test-retest design. They went on to use a bootstrapping technique to estimate the uncertainty of the proportion of agreement. The aims of this short communication are (1) to demonstrate that the sampling distribution of the proportion of agreement is well known (the binomial distribution), making the technique of 'bootstrapping' redundant, and (2) to suggest a much simpler, more sensitive method of assessing the stability of a psychometric questionnaire, based on the test-retest differences (within-individuals) for each item. Adopting methods similar to Wilson and Batterham, 97 sport students completed the Social Physique Anxiety Scale on two occasions. Test-retest differences were calculated for each item. Our results show that the proportion of agreement ignores the nature of disagreement. Items 4 and 11 showed similar agreement (44.3% and 43.3% respectively), but 89 of the participants (91.8%) differed by just +/-1 point when responding to item 4, indicating a relatively stable item. In contrast, only 78 of the participants (80.4%) recorded a difference within +/- 1 point when responding to item 11, suggesting quite contrasting stability for the two items. We recommend that, when assessing the stability of self-report questionnaires using a 5-point scale, most participants (90%) should record test-retest differences within a reference value of +/- 1.  相似文献   

Felder and Silverman's Index of Learning Styles and Honey and Mumford's Learning Styles Questionnaire: How do they compare and do they predict academic performance?     

N. Van Zwanenberg  L. J. Wilkinson  A. Anderson 《教育心理学》2000,20(3):365-380

Samples of engineering and business students at undergraduate, postgraduate and post-experience levels at two UK universities completed the Index of Learning Styles (ILS) (N = 284) or the (Learning Styles Questionnaire LSQ) (N = 182) and a biographical data questionnaire. Broad psychological aspects of the two learning style instruments are examined and compared. Psychometric properties of the instruments, including factor structure, internal reliability and inter-scale correlation are analysed. Potential limitations are commented on, in particular those related to the construct validity and relatively low internal reliability of the ILS scales (alpha = 0.41 to 0.65). These compare with alphas of 0.59 to 0.74 for the LSQ. Relationships between the scales are discussed and a circumplex arrangement of the LSQ is proposed. Proposals for augmenting the circumplex are made. Academic performance results and scores on each of the two instruments are compared. The general lack of significant correlations between learning style scores and performance in these samples is discussed. Conclusions are drawn about the disappointing psychometric robustness of the measures, the activity-centred nature of learning styles and the advantages of viewing styles as a circumplex.  相似文献   

The Roles of Intuition and Informants’ Expertise in Children's Epistemic Trust          下载免费PDF全文

Jonathan D. Lane  Paul L. Harris 《Child development》2015,86(3):919-926

This study examined how children's intuitions and informants’ expertise influence children's trust in informants’ claims. Three‐ to 8‐year‐olds (N = 192) watched videos in which experts (animal/biology experts or artifact/physics experts) made either intuitively plausible or counterintuitive claims about obscure animals or artifacts. Claims fell either within or beyond experts’ domains of expertise. Children of all ages were more trusting of claims made by informants with relevant, as opposed to irrelevant, expertise. Children also showed greater acceptance of intuitive rather than counterintuitive claims, a differentiation that increased with age as they developed firmer intuitions about what can ordinarily happen. In summary, children's trust in testimony depends on whether informants have the relevant expertise as well as on children's own developing intuitions.  相似文献   

Digital media as a reflective tool: creating appropriate spaces for students to become introspective     

Lane Perry  Lee Stoner  Max Schleser  Krystina R. Stoner  Daniel Wadsworth  Rachel Page 《Compare》2015,45(2):323-330

Global citizenship and competency development have become integral parts of political, economic and education discourses. This is particularly true in the USA, where higher education institutions are answering the global citizenship call through the promotion of short-term study abroad. Unfortunately, the ‘just do it’ analogy too often influences the ideology of study abroad, whereby simply providing students with an international experience is perceived to be sufficient in shaping global citizenship. Global citizenship, as an educational outcome, is optimally facilitated when educational experiences are married with appropriate pedagogy, including the shaping of subsequent understandings and actions with critical reflection. We postulate that reflective experiences can be further enhanced by meeting students on the platforms and forums where they live, communicate and already engage. Specifically, this communication, using the context of short-term study abroad programmes, will argue that: (1) critical reflection is an essential step to fostering global citizenship and (2) digital story telling (mobile pedagogy) can be a powerful tool for enriching the critical reflection process.  相似文献
