Some determinants of sick leave for respiratory disease : occupation, asthma, obesity, smoking and rehabilitation
No full textThe cost to society of sick leave and disability pensions is currently the most urgent economic problem in Sweden. The availability of a large sick-listing database, Collective Group Health Insurance, AGS (in Swedish: Avtalsgruppsjukförsäkring) provides a rare opportunity to study sick leave in Sweden. Periods of sick leave exceeding 14 days are recorded together with a mandatory diagnosis by a physician, gender, age, residential area, name of the employer, and occupation.Aim: The overall aim was to investigate some determinants of sick leave because of respiratory disease, and to validate the AGS sick leave register regarding asthma.Methods: In paper I data of sick leave periods exceeding 14 days, for all manual and service employees in the private sector in Sweden during 1992-94 (n--221,249) were analysed with special regard to respiratory diseases and occupation. In paper 11 a validated asthma qpestionnaire was distributed to persons less than 56 years of age registered with a sick leave period starting in 1994 due to a) asthma, b) any other respiratory diagnosis and c) a random sample of 8% of all persons registered under any other diagnosis. In papers III, IV and V a diagnosis of asthma was made using a three-stage model (questionnaire, telephone interview and clinical examination) in persons less than 56 years of age on sick leave due to any respiratory disorder. In paper III the prevalence of obesity was investigated; in paper IV differences between subjects with and without a previous asthma diagnosis were studied and in paper V the long-term effects of a structured rehabilitation programme for asthmatics were analysed.Results: The incidence of long-term (>=90 days) sick leave due to respiratory diseases differed three times between occupations. There was a high correlation (r=0.80) between the incidence of long-term sick leave due to respiratory disease and long-term sick leave due to other conditions, suggesting that market and selection factors may play an important role in determining the overall risk of sick leave in various occupations. Agricultural workers, industrial workers, food industry workers and painters were occupations with an increased risk of respiratory sick leave. In the questionnaire study, asthma was found to be an underreported diagnosis, approximately by a factor of three. In the study of obesity in paper III the prevalence of obesity in asthmatics on sick leave was 20.7%, compared with 13.7% in the non-specific pain patients on sick leave and in 6.5% of a random general population sample (pConclusions: Major differences regarding long-term sick leave due to respiratory disease were found among manual and service occupations. Several occupations, where exposure to respiratory sensitisers and irritants are known to occur, were among those where workers had an increased risk of long-term respiratory disease. There is evidence that asthma is an underreported diagnosis among persons on sick leave due to respiratory diagnosis, either because the reason for an asthma exacerbation is stated on the certificates of illness, or that asthma is not diagnosed among persons seeking medical attention due to respiratory problems. This is most evident in mild disease but also among smokers. The prevalence of asthma among persons on sick leave due to respiratory symptoms was 27% in the questionnaire study and 43% when the structured three-stage model for an asthma diagnosis was employed. Persons on sick leave for more than 14 days due to respiratory symptoms should therefore be clinically investigated with the suspicion of asthma. Obesity is substantially more prevalent among persons with asthma than in a general population sample, especially among women. It is, however, not clear whether the increased prevalence of obesity among asthmatics reflects a true increase of obesity in persons with asthma or whether asthma-like symptoms occur because of obesity. Obesity and asthma could also have a common primary factor. Morphological studies on obese patients with asthmatic symptoms are needed.Smoking seems to worsen asthma symptoms during exacerbations in patients with mild disease, leading to periods of sick leave where the duration is similar to that which is found in patients with more severe asthma. The extensive in-patient asthma rehabilitation programme had major effects on sick leave only for those who did not currently smoke. This could indicate that smoking is the major determinant for respiratory sick leave, regardless of cause and regardless of treatment.List of scientific papersI.

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

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
