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
Square Dancing with the Stars to Enhance Dynamic Hirschman Linkages?
No full textIn this Presidential Address, the author takes the reader on a reconnaissance of his life and time as a regional scientist. He points out scenery he found scintillating along the way, hoping that some may pick up the banner and chew on a few of the ideas for a while. He suggests a revisit to Albert O. Hirschman’s notion of key sectors and more empirical analysis related to Marcus Berliant’s and Masahisa Fujita’s notion of knowledge creation and transfer.Presidential Address, San Antonio, Texas, March 29, 2014 (53rd Meetings of the Southern Regional Science Association
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
Quality of life, functional status and cost-effectiveness of treatment after femoral shaft fractures in Malawi. A comparison of skeletal traction and intramedullary nailing in a low resource setting.
No full textIntroduction: The incidence of femoral shaft fractures in Low- and Middle-Income Countries(LMICs) ranges from 15.7 to 45.5 per 100,000 people per year. A recent study in Malawi, a low-income country (LIC), estimated the national incidence of femoral shaft fractures to be 26.5 per 100,000 people per year, and the prevalence at 1.38 per100,000 population. The femur is one of the principal weight-bearing bones in the body. Hence fractures of the femoral shaft affect weight bearing and mobility, which in turn affects various aspects of quality of life. Furthermore, these fractures occur frequently in the economically productive age group resulting in varying degrees of economic loss both for the patients, their families and the nation. The overall aim of this thesis was to compare the quality of life and functional status of adult patients with femoral shaft fractures treated with intramedullary (IM) nailing and skeletal traction.
Methods: This thesis is based on 4 studies. The first study assessed the clinimetric properties of the Chichewa EQ-5D-3L questionnaire. The questionnaire was administered to a sample of adult patients with both traumatic and non-traumatic musculoskeletal conditions. The second study translated and culturally adapted the English Short Musculoskeletal Function Assessment (SMFA) questionnaire into Chichewa using the multi-step linguistic validation (LV) method. The clinimetric properties of the Chichewa SMFA were then assessed by administering the questionnaire to adult patients with both traumatic and non-traumatic conditions. The third study assessed quality of life and functional status in adult patients with femoral shaft fractures treated with either IM nailing or skeletal traction. Quality of life and functional status were assessed using the Chichewa EQ-5D-3L and SMFA questionnaires respectively. Assessment was done at 6 weeks, 3 months, 6 months, and 1-year post injury. The fourth study assessed the cost-effectiveness of the two treatment modalities from both the government health care payer and societal perspectives. The time horizon was 1-year. This was a cost utility analysis where QALYs were calculated from EQ-5D-3L index scores and direct treatment costs calculated using time and motion analysis were obtained from a prospective costing study. Indirect costs included patient lost productivity, and patient transportation, meal, and childcare costs associated with hospital stay and follow-up visits.
Results: Both the Chichewa EQ-5D-3L and SMFA versions were found to demonstrate adequate validity, internal consistency, floor/ceiling effects, and reliability. Hence, they were found to be valid and reliable tools for measuring quality of life and functional status in patients with musculoskeletal conditions in populations where Chichewa (or Chinyanja) is the primary language. Patients treated with IM nailing had better quality of life and function at 6 weeks, 3 months and 6 months after injury, compared to those treated with skeletal traction. The study also found that IM nailing patients returned to work earlier than skeletal traction patients. There were no differences in quality of life and function at 1-year post injury. However, 30% of skeletal traction patients converted to IM nailing due to failed treatment; these would have ended up with poor quality of life and function at 1 year if they had continued with skeletal traction treatment. IM nailing was found to be a dominant approach being both cost saving and more effective than skeletal traction. Furthermore, the sensitivity analysis showed more than 90% certainty of the findings.
Conclusion: In summary, the studies included in this thesis have established that the Chichewa EQ-5D-3L and SMFA questionnaires are valid and reliable tools that can be used to assess quality of life and function respectively, in adults with musculoskeletal problems who use Chichewa as their primary language. IM nailing was associated with better quality of life, better function and earlier return to work, and was more cost-effective than skeletal traction in the treatment of adult femoral shaft fractures.Doktorgradsavhandlin

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
