Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
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
Weight loss surgery for non-morbidly obese populations with type 2 diabetes: is this an acceptable option for patients?
No full textAim To explore the views of non-morbidly obese people (BMI 30-40 kg/m2) with type 2 diabetes regarding: (a) the acceptability of bariatric surgery (BS) as a treatment for type 2 diabetes, and (b) willingness to participate in randomised controlled trials comparing BS versus non-surgical intervention. BACKGROUND: Despite weight management being a key therapeutic goal in type 2 diabetes, achieving and sustaining weight loss is problematic. BS is an effective treatment for people with morbid obesity and type 2 diabetes; it is less certain whether non-morbidly obese patients (BMI 30-39.9 kg/m2) with type 2 diabetes benefit from this treatment and whether this approach would be cost-effective. Before evaluating this issue by randomised trials, it is important to understand whether BS and such research are acceptable to this population. METHODS: Non-morbidly obese people with type 2 diabetes were purposively sampled from primary care and invited to participate in semi-structured interviews. Interviews explored participants' thoughts surrounding their diabetes and weight, the acceptability of BS and the willingness to participate in BS research. Data were analysed using Framework Analysi
Perceptions of weight, diabetes and willingness to participate in randomised controlled trials of bariatric surgery for patients with type 2 diabetes mellitus and body mass index 30-39.9 kg/m2
No full textPurposeEvidence from high-quality randomised controlled trials (RCTs) is needed to establish the long-term benefit of bariatric surgery in people with type 2 diabetes mellitus (T2DM) and body mass index (BMI) 30–39.9 kg/m2. However, willingness amongst this group to be randomised and undergo surgery is uncertain. This study assessed UK patients’ perceptions of their weight and diabetes, and associations with willingness to participate in RCTs involving bariatric surgery, amongst this population.Materials and MethodsPostal survey of 1820 patients from four regions in England. Eligible patients were as follows: BMI 30–39.9 kg/m2, 18–74 years, diagnosis of T2DM ?2 years. A reminder survey was sent after 4 weeks. Independent predictors influencing patients’ willingness to consider RCT participation were identified using multiple logistic regression analysis.ResultsThirty-four per cent (614/1820) of patients responded. Weight was considered to be harder to control than diabetes [468/584 (80 %) vs. 107/600 (17 %)]. More people reported a negative impact on life for weight rather than diabetes [379/579 (63 %) vs. 180/574 (31 %)]. Feeling unsatisfied/very unsatisfied with weight loss ability was common 261/578 (45 %). Sixty-four per cent (379/594, CI?=?60–68) were willing to consider participating in an RCT. In multivariate analysis, negative impact of weight on life (OR?=?2.55, 95 % CI?=?1.68–3.89, P?<?0.001) and feeling unsatisfied with weight loss ability (OR?=?2.47, 95 % CI?=?1.55–3.95, P?<?0.001) positively influenced patients’ willingness to participate in an RCT.ConclusionStrong patient interest supports the feasibility of such trials for this group. Perceptions of obesity negatively impacting on life and difficulties in achieving weight loss were common and influenced attitudes to potential participation in bariatric surgery RCTs
Magdalenapalpus Mesa, Welbourn and Evans 2009
No full textMagdalenapalpus Mesa, Welbourn and Evans, 2009 Type species. Meyeraepalpus strandtmanni Smiley, Frost and Gerson, 1996, by original designation. Diagnosis. All life stages: dorsal opisthosoma with 12 or 13 pairs of lanceolate setae; c 2, d 2, and e 2 present; seta f 2 present or absent; setae e 2 inserted in more-or-less marginal position; setae h 2 similar in size and form to other dorsal setae; palps 5 -segmented, setal formula 0,0,0,2,3(1); immature stages with anterior margin of prodorsum smoothly rounded, without projections/notches, gnathosoma not concealed; ventral plate absent; 3 pairs of pseudanal setae (ps 1–3) on weakly developed anal plates. Adult female: anterior margin of prodorsum deeply incised, forming 1 pair of broad fleshy lobes, each lobe bearing setae v 2 (also in male); gnathosoma partially concealed by anterior margin of prodorsum (also in male); genital plate weakly developed, membranous; metapodal plates not developed; coxae I without setae 1 c; trochanters I–IV 0- 0-1 -0 (v ′ absent on tr I–IV; l ′ present on tr III); femora I–IV 3 - 3 - 2 - 1; genua 1 - 1 -0-0 (d present on ge I–II); tibiae 4 - 4 - 3 - 3; tarsi I–IV 8 (1)- 8 (1)- 4 - 4 (without tc′′). Solenidia of male much thicker and longer than in female. Species. Three species: M. strandtmanni, M. caperatus, M. forsteri. Hosts and distribution. Casuarinaceae, Australia. Remarks. The new species described herein differ from the type species by lacking seta f 2. Although this is an important difference, these species share the same leg setation, a deeply incised prodorsum with setae v 2 inserted on the resultant lobes, and a partially concealed gnathosoma.Published as part of Beard, Jennifer J., Seeman, Owen D. & Bauchan, Gary R., 2014, Tenuipalpidae (Acari: Trombidiformes) from Casuarinaceae (Fagales), pp. 1-157 in Zootaxa 3778 (1) on page 51, DOI: 10.11646/zootaxa.3778.1.1, http://zenodo.org/record/25133
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
