Women, Labor Segmentation and Regulation: Varieties of Gender Gaps
No full textThis book re-shapes thinking on ‘gender gaps’—differences between men and women in their incomes, their employment and their conditions of work. It shows how the interaction between regulation distance and content, labor segmentation and norms helps us understand various aspects of gender gaps.
It brings together leading authors from industrial relations, sociology, politics, and feminist economics, who outline the roles the family, state public policy, trade unions and class play in creating gender gaps, and consider the lessons from international comparisons. While many studies have focused on the role of society or organizations, this book also pays attention to the role of occupations in promoting and reinforcing gender gaps, discussing groups such as apparel outworkers, film and video workers, care workers, public-sector professionals like librarians, chief executives, academics, and coal miners.
This book will be of interest to practitioners, policy makers, academics and students interested in understanding why inequality between men and women persists today—and what might be done about it.No Full Tex
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Seven-year experience with polytetrafluoroethylene as above-knee femoropopliteal bypass graft. Is is worthwhile to preserve the autologous saphenous vein?
No full textA 7-year experience with 90 polytetrafluoroethylene (PTFE) femoropopliteal bypass grafts in the above-knee (AK) position is presented. The 5- and 7-year actuarial patency rate was 58.3%. No statistical difference was found between the patency rate of this series and that of a group of 17 AK and 77 below-knee (BK) femoropopliteal bypass grafts performed during the same period with the autologous saphenous vein (ASV). During the follow-up period (range 6 to 84 months, mean 42 months) a new bypass in a more distal location was required in 20 limbs. The ASV was available in seven of the eight PTFE graft failures and in only one of the 12 ASV failures. The 3-year patency rate of these new groups was 58.3% and 16.7%, respectively (p less than 0.02). Eighteen of the 48 deaths occurring during the follow-up period were related to atherosclerotic heart disease, whereas only one patient underwent coronary artery bypass grafting. Five hundred patients randomly selected from our series of myocardial revascularization procedures were reviewed. In five a femorodistal reconstruction was performed before coronary artery bypass, and in only two (0.4%), the ASV was not available. PTFE use in the AK position may be a reasonable alternative to the ASV to preserve it for additional treatment of more distal occlusive disease. There is no evidence that such a need exists for further treatment of coronary artery disease
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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

No full textRetroperitoneal descending thoracic aorta-femoral artery bypass was performed in 18 patients over an 11-year period. The reconstruction was carried to both femoral arteries in 12 patients; in the other 6, only a single femoral artery was revascularized. The operative indication in Group 1 (3 patients) was infection of a previous aortoiliac reconstruction; in Group 2 (12 patients), occlusion of a previous aortoiliac reconstruction; and in Group 3 (3 patients), aortoiliac occlusive disease in which a direct transabdominal procedure was considered hazardous. Follow-up ranged from 6 months to 9 years (mean, 40 months). Cumulative patency rate was 96 ± 3.9% at 1 year and 85 ± 8.1% at 5 years. No alterations of serum creatinine and blood urea nitrogen values were recorded seven days and 6 months after operation. Retroperitoneal thoracic aorta-femoral artery bypass is a useful technique for accomplishing lower limb revascularization in patients in whom exposure or availability of the abdominal aorta poses a specific hazard. © 1985, The Society of Thoracic Surgeons.

Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
