Energy Expenditure Characteristics of Guo Lin Qi-Gong Exercise in Cancer Survivors: A Preliminary Report
No full textGuo Lin Qi-gong is a Chinese body-mind exercise, which includes a number of standing and walking components using a unique inhale-inhale-exhale breathing pattern and has been practiced by thousands of cancer survivors in China. Yet, its energy expenditure (EE) characteristics have not been studied.
PURPOSE: To determine EE characteristics of 9 key components of Guo Lin Qi-gong and compare them with a free-living walking.
METHOD: 40 (20 males/females; Age = 61.98±7.31 yr., HT = 163.92±6.19 cm, WT = 63.04±9.82 kg, Fat% by DXA =28.30±9.36) Chinese long-term (16.54±4.12 yr.) cancer survivors, who have practiced Guo Lin Qi-gong since their cancer diagnosis, were recruited for the study. Their resting metabolic rates (RMR) were measured by COSMED FITMAT calorimetry and EE (VO2 ml-1) during Guo Lin Qi-gong practice by component were measured by COSMED K4b2 pulmonary. Components were performed in a counter-balanced order, 10 min per component, with a 5-10 min break between each. The speed of the walking components was recorded. For comparison, their EE during a 10-min free-living walk at a comfortable speed were also measured. MET values of each component were computed.
RESULTS: M±SD of RMR are 204.74±34.15 ml/min; therefore, a slightly lower 1-MET value (3.29±.58 ml/min/kg). MET values of Guo Lin Qi-gong components, along with heart rate and walking speed, are summarized below (MET, Heart Rate in beat/min, & Speed in meter/min):
1. Warm-up (1.80, 88.22±12.45, NA)
2. Wind Breath Natural Walking (3.65, 102.06±13.65, 38.77±14.60)
3. Step-in-Place Gong (2.65, 96.28±13.34, NA)
4. Up-and-Down/Open-and-Close (2.72, 97.22±11.65, NA)
5. One-Step Toe Touch Walking (3.21, 98.68±12.07, 12.13±3.69)
6. Two-Step Toe Touch Walking (2.97, 98.55±11.64, 18.20±4.92)
7. Three-Step Toe Touch Walking (3.10, 100.01±12.57, 16.08±4.20)
8. Strong Wind Breath Fast Walking (4.83, 115.49±15.56, 72.90±11.59)
9. Close-up (1.89, 91.30±12.70, NA)
10. 10-Min Free-Living Walking (3.58, 96.09±12.32, 56.56±13.34).
CONCLUSION: Guo Lin Qi-gong is a low-to-moderate intensity aerobic exercise. With its unique breathing pattern, relative oxygen intake of several components is rather large considering the slow walking speed employed. Guo Lin Qi-gong is an excellent exercise format for cancer survivorship
Effects of Long-Term Guo Lin Qi-Gong Practice on Cancer Survivors\u27 Quality of Life and Aerobic Capacity: A Preliminary Report
No full textWhile the positive impact of aerobic and strength exercises on quality of life (QOL) and physical functions among cancer survivors has been well documented, limited efforts have been made to examine the effects of body-mind exercises.
PURPOSE: To determine the effects of long-term Guo Lin Qi-gong practice on QOL and aerobic capacity in cancer survivors. Guo Lin Qi-gong is a body-mind exercise that has been practiced by thousands of cancer survivors in China.
METHOD: 40 (20 males/females) Chinese long-term cancer survivors, who have practiced Guo Lin Qi-gong since their cancer diagnosis, were recruited in Shanghai, China and a control group (n=40) matched by types of cancer, age, gender and survival years was then recruited. Both groups were administered SF-36, a generic QOL measure (Ware & Donald-Sherbourne, 1992), Beck Depression Inventory (Beck, 1961), and did a 6-min walking test, and all results were compared using paired t-tests.
RESULTS: Both groups were well matched by Age in yr., HT in cm, WT in kg, DXA Fat% & Survival yr. (M±SD): Guo Lin Qi-gong (61.98±7.31, 163.92±6.19, 63.04±9.82, 28.30±9.36, 16.54±4.12) vs. Match-Control (60.98±7.75, 164.40±7.49, 64.14±10.95, 29.31±8.37, 15.67±4.61). It was found that long term Guo-Lin Qi-gong practice led to:
1. Better health status and QOL [e.g., Guo Lin Qi-gong group\u27s SF-36 and related subscale scores are all higher than the Control group, and the difference in body pain scores, 91.35±11.33 vs. 84.60±15.61 (note: the higher SF-36 score, the better health) is statistically significant, p \u3c.05];
2. Less depression (e.g., Guo Lin Qi-gong group 7.55±3.78 vs. Control group 8.91±6.64) although the difference was not statistically different (p \u3e.05);
3. Higher health fitness level (e.g., Guo Lin Qi-gong group walked longer distances, 566.65±70.63 vs. 542.68±85.19 meters, and took more steps, 837.75±81.05 vs. 775.95±71.56 steps, p \u3c.05, in 6-min walking test than the Control group).
Furthermore, it was found that Guo Lin Qi-gong group experienced a much lower cancer recurrence rate (4/40 = 10%) than the Control group (12/40 = 30%).
CONCLUSION: Guo Lin Qi-gong demonstrated to be an effective means in improving QOL and aerobic capacity for cancer survivors. Its possible effect in preventing cancer recurrence should be further investigated
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
