Fig. 1. A) The proximal femur was marked to identify three locations: base of the head, the neck-trochanter junction, and the base of the lesser and greater trochanters. B) The specimens were cut to provide three sections per femur, and trabecular cores were obtained from these three bone sections 6

Materials and Methods: A total of 162 trabecular bone cores were obtained from six regions (femoral head, superior and inferior regions of the neck, and superior/middle and inferior regions of the trochanter) of twenty-seven normal femora of Korean male cadaver donors, aged 40-90 years. These specimens were scanned using high-resolution micro-computed tomography (micro-CT). The following 3D microstructural parameters were calculated: bone volume fraction (BV/TV), trabecular thickness (Tb.Th), separation (Tb.Sp) and number (Tb.N), structure model index (SMI) and degree of anisotropy (DOA).
Results: The results showed that the trabecular microstructure changed significantly with age, as well as varied from different regions of the proximal femur. There was a significant decrease in bone volume fraction and an almost identical decrease in trabecular thickness associated with aging at any region. Regional analysis demonstrated a significant difference not only in BV/TV, Tb.Th, Tb.Sp, Tb.N, DOA between superior and inferior neck, but also difference in BV/TV, Tb.Sp, Tb.N, SMI, DOA between superior and inferior trochanter.
Conclusions: Age-related changes in bone loss and trabecular microstructure within the male proximal femur are not uniform in this Korean cadaveric population. As a result of mechanical and age-related adaptation, significant regional variations in microstructural properties of trabecular bone are likely to be an important factor affecting the mechanical properties of the proximal femur

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

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

Reflections on the Crisis of Comparative Literature in the Contemporary West
Full text linkIn their Article Reflections on the Crisis of Comparative Literature in the Contemporary West Zhoukun Han and Wen Quan review the challenges met during the evolution of comparative literature as a discipline between the turn of nineteenth century and 1958. They maintain that comparative literature in the contemporary West is indeed experiencing a crisis, explicate the reasons for this. Apart from the pursuit of sameness inherent in conventional comparative studies and the position of western-centrism, the shift from literary comparison to cultural study has exacerbated the crisis. In view of this situation, some western scholars call for a return to comparison and literature. Furthermore, they resuscitate the conception of world literature and give it new meanings to address the crisis. Meanwhile Chinese scholars have responded with cross-civilization studies and variation theory, which promises of a new theoretical construction for comparative literature
