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
Functional outcomes in high risk ICU patients in Central Australia: a prospective case series
No full textINTRODUCTION: This case series reports the functional outcomes of a prospective group of patients, thought to be at high risk for future morbidity, admitted to a rural intensive care unit (ICU) for a life-threatening illness. METHODS: This prospective longitudinal observational study conducted between February and August 2009 in the Alice Springs Hospital ICU included patients considered 'high risk', as evidenced by profound physiological derangement. The participants were prospectively recruited when pre-defined criteria were met. Functional outcomes were measured by performance in the six-minute walk test, and the ability to undertake activities of daily living. Persisting morbidity was crudely measured by hospital re-admission rate. Mortality was measured at 6 months. RESULTS: Eighteen patients consented to take part in the study. Fourteen were Indigenous, and 14 were medical patients. Six-minute walk distance did not improve between ICU discharge and 6 months, and was significantly below that predicted. Almost all patients achieved scores consistent with full independence in basic activities of daily living. Five achieved scores consistent with independence in domestic activities of daily living. Twelve required at least one re-admission, with half the Indigenous subgroup requiring three or more re-admissions. There were four deaths, all Indigenous patients, and three were homeless.< CONCLUSION: This study demonstrates that follow up in this group at 6 months is both feasible and valuable. There is evidence of persisting morbidity, and increased mortality, particularly among Indigenous patients. Further avenues of research are suggested, including the need for a large multi-centre prospective study.P. J. Secombe, P. C. Stewart, A. Brow
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
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

Effectiveness and safety of conservative management of occult pneumothorax in mechanically ventilated patients: a systematic review protocol
No full textOBJECTIVE: This systematic review aims to synthesize the available evidence investigating the effectiveness and safety of conservative management of occult pneumothorax in mechanically ventilated patients. INTRODUCTION: Occult pneumothorax is air within the pleural cavity that is diagnosed on a CT scan but was not suspected on the basis of preceding clinical examination or supine chest x-ray. Currently, there is no consensus on how to manage occult pneumothoraces, especially in patients requiring mechanical ventilation. It is common practice to place a prophylactic intercostal catheter (ICC) to stop the potential development of a tension pneumothorax; however, there is a 20% risk of major complications from the ICC insertion. Recent evidence suggests that occult pneumothorax in mechanically ventilated patients can be managed conservatively, rather than using a prophylactic ICC as first-line management. INCLUSION CRITERIA: This review will include studies investigating stable patients of all ages who were diagnosed with traumatic occult pneumothorax via CT scan, received mechanical ventilation, and underwent either conservative management or ICC insertion. METHODS: Eligible studies will include randomized and non-randomized controlled trials, and prospective and retrospective cohort studies. PubMed, Embase, CINAHL, Web of Science and Cochrane Central Register of Controlled Trials will be searched. International Clinical Trials Registry, Australian New Zealand Clinical Trials Registry and ClinicalTrials.gov will be searched for unpublished studies. All included studies will be critically appraised using standardized JBI tools, with no exclusions based on methodological quality. Studies will, where possible, be pooled in statistical meta-analysis, with impact of methodological quality to be explored through sensitivity analysis.Jeremy A.
