Psychometrics of Halpin Nausea and Vomiting Scales for use in clinical practice
No full textSession presented on:Tuesday, July 23, 2013:
Purpose: To communicate psychometric properties of the new 0-5 Halpin Nausea and Vomiting (HNV) scales with descriptors, so learners can use scales in clinical practice.
Methods: A methodological design was applied to establish psychometrics of HNV scales using three groups of patients, N = 163. Group I was admitted with a diagnosis of NV, n=54. Group II consisted of cancer patients scheduled for chemotherapy, n=52. Group III was a control group with medical-surgical diagnoses and no expected NV, n=57.
Results: HNV scales had a high inter-rater reliability (Kappa test=.851, p\u3c.001). Concurrent validity was established between the HNV scales and Morrow\u27s worst nausea ratings, significant\u27(r=.318, p=.03). HNV was found to measure fine differences between and within groups, establishing sensitivity. Chi square tests were non-significant for ethnicity, gender, coronary artery disease, hypertension, diabetes, congestive heart failure, other medical surgical diagnosis and risk for PONV. Group I had more nausea patients (X2=63.94, p\u3c.001) and higher degree of the diagnosis of pancreatitis (X2=8.72, p=.01). Group II had more cancer (X2=76.00, p\u3c.001), and chemo patients (X2=93.06, p\u3c.001). In terms of age, one way analysis of variance indicated that the groups are significantly different (F=6.12, p=.003). Scheffe\u27s test indicates that group I (the NV group) were significantly younger (p\u3c.05) than the control and the cancer group. Group II and III were homogenous with no significantly difference in age.
Conclusion: Accurate assessment of NV with valid and reliable scales can lead to more accurate and timely treatment. Alleviation of patient\u27s discomfort is improved by scales with descriptors because the specific patient response has an individual measurement. Patients can rank and use the descriptors to communicate their symptom severity. Knowing the intensity of NV predictors in surgical and chemotherapy patients supports use of HNV scales to promote symptom management and improves quality of life
Emergence of consensus and shared vocabularies in collaborative tagging systems
No full textThis article uses data from the social bookmarking site del.icio.us to empirically examine the dynamics of collaborative tagging systems and to study how coherent categorization schemes emerge from unsupervised tagging by individual users. First, we study the formation of stable distributions in tagging systems, seen as an implicit form of “consensus” reached by the users of the system around the tags that best describe a resource. We show that final tag frequencies for most resources converge to power law distributions and we propose an empirical method to examine the dynamics of the convergence process, based on the Kullback-Leibler divergence measure. The convergence analysis is performed for both the most utilized tags at the top of tag distributions and the so-called long tail. Second, we study the information structures that emerge from collaborative tagging, namely tag correlation (or folksonomy) graphs. We show how community-based network techniques can be used to extract simple tag vocabularies from the tag correlation graphs by partitioning them into subsets of related tags. Furthermore, we also show, for a specialized domain, that shared vocabularies produced by collaborative tagging are richer than the vocabularies which can be extracted from large-scale query logs provided by a major search engine. Although the empirical analysis presented in this article is based on a set of tagging data obtained from del.icio.us, the methods developed are general, and the conclusions should be applicable across other websites that employ tagging
A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
