Star formation histories in H II galaxies. I. Optical and radio observations
No full textIn this paper we report CCD photometry in broad band B, R, and I colors, as well as in the H , for a sample of eight Hii galaxies with strong radio emission. In addition, we present new radio continuum observations in the frequency range between 8 and 15 GHz. For seven of these galaxies, previous radio continuum observations have been reported by Deeg et al. (1993); data on Haro 1 are presented here for the rst time. Their unusual radio spectra, according to Deeg et al., are a consequence of rapidly changing star formation rates in their past. An independent veri cation of this conclusion is the motivation for the optical observations reported here. Their interpretation is the subject of the next article in this series. The new radio measurements con rm the interpretation of the radio spectra by Deeg et al. In combination with extinction corrected H fluxes, the new radio measurements allow the determination of thermal radio fluxes - a fundamental parameter for star formation rates - with higher reliability than is possible from one wavelength domain alone. Overlays of optical observations at different colors with radio maps, as well as a search of the literature, indicates that all sample galaxies are in interacting environments, which is a possible prerequisite for the strength of the radio emission and star formation observed in these galaxies

The Birth of the Buddha and Related Episodes as Represented in Chinese Art
No full textThe essay treats the theme of the representation of the events surrounding the birth of the Buddha and the ceremonies commemorating these episodes in India, China, Korea and Japan. It deals in particular with a specific iconology associated with the episode of the Seven Steps, which depicts the child Buddha with the right arm aloft and the left pointing to the earth in the act of proclaiming his superiority over the whole universe.
This image is unknown in the Indian cultural context and is still the object of celebrations held on the eighth day of the fourth month of the Chinese, Korean, Japanese and South-East Asian lunar calendar.
The study examines the earliest Chinese translations of the life of the Buddha (Xiuxing benqi jing, Taizi ruiying benqi jing) and other Chinese primary sources describing the cerimonies commemorating the birth of the Buddha, as well as a selection of bronze statuettes and stone reliefs from China datable from the 2nd to 5th centuries and others items from Korea and Japan

Equine recurrent uveitis - A spontaneous horse model of uveitis
No full textEquine recurrent uveitis (ERU) is an autoimmune disease that occurs with a high prevalence (10%) in horses. ERU represents the only reliable spontaneous model for human autoimmune uveitis. We already identified and characterized novel autoantigens (malate dehydrogenase, recoverin, CRALBP) by analyzing the autoantibody-binding pattern of horses affected by spontaneous recurrent uveitis (ERU) to the retinal proteome. CRALBP also seems to be relevant to human autoimmune uveitis. Proteomic screening of vitreous and retinal samples from ERU diseased cases in comparison to healthy controls has led to the identification of a series of differentially regulated proteins, which are functionally linked to the immune system and the maintenance of the blood-retinal barrier.

A risk profile for identifying community-dwelling elderly with a highrisk of recurrent falling: results of a 3-year prospective study
No full textIntroduction: The aim of the prospective study reported here was to develop a risk profile that can be used to identify community-dwelling elderly at a high risk of recurrent falling. Materials and methods: The study was designed as a 3-year prospective cohort study. A total of 1365 community-dwelling persons, aged 65 years and older, of the population-based Longitudinal Aging Study Amsterdam participated in the study. During an interview in 1995/1996, physical, cognitive, emotional and social aspects of functioning were assessed. A follow-up on the number of falls and fractures was conducted during a 3-year period using fall calendars that participants filled out weekly. Recurrent fallers were identified as those who fell at least twice within a 6-month period during the 3-year follow-up. Results: The incidence of recurrent falls at the 3-year follow-up point was 24.9% in women and 24.4% in men. Of the respondents, 5.5% reported a total of 87 fractures that resulted from a fall, including 20 hip fractures, 21 wrist fractures and seven humerus fractures. Recurrent fallers were more prone to have a fall-related fracture than those who were not defined as recurrent fallers (11.9% vs. 3.4%; OR: 3.8; 95% CI: 2.3-6.1). Backward logistic regression analysis identified the following predictors in the risk profile for recurrent falling: two or more previous falls, dizziness, functional limitations, weak grip strength, low body weight, fear of falling, the presence of dogs/cats in the household, a high educational level, drinking 18 or more alcoholic consumptions per week and two interaction terms (high educationx18 or more alcohol consumptions per week and two or more previous falls x fear of falling) (AUC=0.71). Discussion: At a cut-off point of 5 on the total risk score (range 0-30), the model predicted recurrent falling with a sensitivity of 59% and a specificity of 71%. At a cut-off point of 10, the sensitivity and specificity were 31% and 92%, respectively. A risk profile including nine predictors that can easily be assessed seems to be a useful tool for the identification of community-dwelling elderly with a high risk of recurrent falling. © International Osteoporosis Foundation and National Osteoporosis Foundation 2006

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
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
