HUMAN BALANCE EVALUATION IN SUBJECTS WITH CERVICAL INJURIES COMPARED TO HEALTHY SUBJECTS: RESULTS OF A PILOT STUDY
No full textIntroduction It is very important that forensic medicine properly calculates the biological damage not only through the disturbance indicated
by the patient, but more accurately through instrumental diagnosis. Our aim was to verify through posturography the qualitative
and quantitative alterations of postural stability in subjects with cervical trauma, compared to the control group. Methods We analysed 78
subjects, selecting 42 volunteers and distinguishing a control group of 22 normal men (NM) and a group of 20 men (WM) with a positive
anamnesis of whiplash injury for six months. Through a force platform, we recorded the Centre of Pressure (CoP) movements of these
groups, both with their eyes open, and closed. The data was used to compare between the two groups, with both open and closed eyes.
Results During the closed eyes test, those subjects with cervical injuries, displayed a significant increase in anterior-posterior oscillation
velocity (p<0.05) compared to the control group, with a significant reduction (p<0.01) of ratio between Shifting Length (SL) of CoP on the
polygon support and total envelop area (EA, mm2) of CoP movements in the polygon support (SL/EA-ratio, mm-1). During the closed eyes
test, subjects with cervical injury showed a significant anterior shifting of the mean position of CoP compared to the other group performing
the open eyes test. Discussion Our results suggest that posturographic tests can be used to assess and confirm human body imbalance
in subjects with whiplash injury. Further studies with more subjects from both sexes are necessary to confirm this pilot study. References

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
Influence of family history of NIDDM on basal metabolic rate in sedentary and active women
No full textAIM AND METHODS: The influence of family history of non-insulin-dependent diabetes (NIDDM) on basal metabolic rate (BMR) has been investigated in 116 voluntarily women: 25 sedentary and 34 athletes without a family predisposition to type 2 diabetes (FH-); 21 sedentary and 15 athletes with a second degree predisposition to NIDDM (FH+); 10 sedentary and 11 athletes with a first degree predisposition to NIDDM (FH++). RESULTS: The results showed that family history on type 2 diabetes is strongly related to sedentary in women with significant high body weight values and an increased fat mass. There was no significant difference in the body parameters among the athletes groups, confirming the protective role of regular physical activity on these parameters. Analysing basal energy expenditure showed that sedentary FH++ women had a significant increase in BMR in absolute values; however there were no differences in BMR when reported to body weight and body fat-free mass. In contrast, the FH++ athletes group had lower BMR (absolute values) than the sedentary group. No differences were found in the relative BMR either. By comparing the recorded BMR of the groups with the theoretical values, it has been shown that the FH++ athletes had a reduced increase in BMR with respect to the other groups. The FH- athletes showed a higher energy turnover compared to the other women and relative to predicted values. CONCLUSION: This study confirms that family history of type 2 diabetes has an important influence on the phenotype of women and it can be associated with significant metabolic and anthropometric modifications in young healthy subjects. It may also account for changes in the body composition and basal metabolic rate alterations in subjects with a predisposition to type 2 diabetes, by reducing the metabolic basal output expected in active subjects
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
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
INFLUENCE OF FAMILY HISTORY OF TYPE 2 DIABETES ON PHENOTYPE AND PERFORMANCE IN YOUNG PEOPLE OF BOTH SEX.
No full textThe type 2 diabetes is commonly considered a complex genetic disease,
resulting from interactions between multiple genes and environmental factors
without any single factor having strong independent effects. We studied the
influence of family history to type 2 diabetes on physical phenotype of 47 health
adolescents. In both sexes groups with positive family history (FH+) had the
highest values of stature and body weight (p<0.05 for males, not significant for
females), waist circumference (p<0.05 for males, not significant for females), and
wrist circumference (p=0.05 for males, not significant for females). Considering
performance, FH+ males showed a significant higher performance in power
exercises than FH- males; no significant differences were found between FH+ and
FH- female groups. Family history to type 2 diabetes can induce in both sexes
precocious phenotype and performances linked-related variations; more studies
are necessary to confirm these data and to verify preventive interventions
promoting significant life-style changes
