ABSTRACT
The purpose of this study was to investigate the effects of moderate intensity exercise (MIE) and low intensity exercise (LIE) with equal energy expenditure (900 Kcal) on high-density lipoprotein cholesterol (HDL-C). Ten healthy, no smoking habit male college students (18-28 yrs.) counterbalancedly performed treadmill running with MIE at 55%VO2max and walking with LIE at 35%VO2max on 7 days separately. Exercise was performed at 3 hours after dinner. For each trial, blood samples were collected at the morning pre-exercise in a fasted state for baseline, 10 min pre-exercise, 10 min post-exercise (IPE) and 11h post-exercise (11h PE, the next morning in a fasted state). Plasma HDL-C, total-cholesterol(TC), triacylglycerol(TG), and very low-density lipoprotein triacylglycerol (VLDL-TG) were measured. All samples were corrected for plasma volume changes. A significant increase (p<0.05) in HDL-C was observed at IPE and 11h PE after MIE trial, and there was no decrease in TC after both two trials. Both of the increasing magnitude and percentage of HDL-C after MIE were significantly higher than LIE (3.11±1.88mg/dl vs. -0.34 ±.85mg/dl; 8.09±5.24％ vs. -0.74±6.86％). VLDL-TG was significantly decrease after MIE trial but not LIE trial. These results suggest that MIE is better than LIE to elevate HDL-C with equal energy expenditure, and the elevating effect of MIE on HDL-C is related to the consumption of VLDL-TG. It also suggests that 900 Kcal energy expenditure is enough to promote favorable changes in HDL-C by MIE but not LIE.

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

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
Decay of stationary light pulses in ultracold atoms
No full textstanding-wave electromagnetically induced transparency. We rely on full numerical solutions of the Maxwell-
Liouville equations without invoking secular and adiabatic approximations and arbitrary initial state assumptions.
These approximations and assumptions can conceal, e.g., significant loss and diffusion responsible for the decay
of stationary light pulses in cold atomic samples. The complex decay dynamics of a stationary light pulse is
here analyzed in terms of higher-order spin and optical coherences that arise from nonlinear interactions of the
stationary light pulse with the two counterpropagating components of a standing-wave driving field. Specific
results for stationary light pulses in cold 87Rb atoms have been discussed for temperature regimes where the
residual Doppler broadening is negligible
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
