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
The influence of smoking cessation, regular physical exercise and/or physical activity on survival: a 13 years cohort study of the Indonesian population in Jakarta
Full text linkPreventing atherosclerosis with smoking cessation, regular physical exercise and/or physical activity known as SOK (S-top/ no S-moking, sp-O-rt/ physical exercise, wor-K/ physical activity) is a simple preventive measure, which can be applied in the community. To determine the role of SOK on survival, to create cardiovascular risk score for Indonesian patients and to have a special formula to predict survival. A historical cohort study over thirteen years recruited from the subpopulation MONICA patients who resided at three districts of South Jakarta. Patients were divided into two groups, those with SOK and those without (non-SOK group). Assessment included complete history including cardiovascular risk factors (hypertension, diabetic, hyperlipidemia, obesity), physical examination, laboratory examination, twelve-lead ECG recording and level of physical activity/exercise. Outcomes included survival rate and all-cause of mortality. Statistical analysis included kappa statistic and various survival analyses. 479 participants were included in the SOK study. Mean age 46 years (range 25-64), 56% female. Cardiovascular mortality rate (including stroke) was 1.2% per year and 42.9% of mortality caused by heart disease. Survival rate was higher in SOK group compared with non-SOK (95.7% vs 81.1%) with Hazard Ratio (HR) 0.2 for SOK group (95% CI 0.08-0.57, p=0.002) In relation to the cardiovascular mortality rate: 1) any physical activity/exercise (OK) vs no-OK will lower the risk; low-OK (HR 0.4, p=0.003), medium-OK (HR 0.32, p=0.004), high-OK (HR 0.000, p=0.000) 2) Smoking will increase the risk vs non-smoking (HR 4.99, p=0,000). For predicting the cardiovascular events in ten-year time (CV10), we formulated the Jakarta Cardiovascular Score. The score was divided into low-risk (-7-1) with CV10 <10%, average-risk (2-4) with CV10 = 10-20%, high-risk (score > 5) with CV10 >20%. Smoking cessation, regular physical exercise and/or physical activity is an effective method to reduce cardiovascular death, thus enhances the survival. We formulated a simple method to predict cardiovascular events in our community known as the Jakarta Cardiovascular Score.

The profile of physical activity and coronary risk factors in Monica Jakarta survey
No full textA population study was done to know the profile of daily physical activity including sports, and its influence on major coronary risk factors in three districts of Jakarta using questionnaire, physicaL and laboratory examination, and 12 leads ECC. The questionnaire gave the data about physical activity (work load and sport), and smoking habit. Work load was divided into light, moderate and heavy. Sport activity was divided into regular (≥ twice a week, 20 minutes or more), irregular (≤ once or occasional), and no sport activity. In addition, blood pressure (hypertension was grouped according to WHO criteria), total cholesterol (regarded as hypercholesterolemia when > 200 mg%), and ECG were measured. ECG interpretation was done using Minnesota Code. Statistical analysis was done using SPSS. Out of 2400 people there were 2073(86.4%) respondents that consist of 1086 females and 987 males. The profile of physical activity as a whole showed 33.4% light, 50.7% moderate and 15.8% heavy activity. OnLy 22.5% of respondents had sport regularly, while 30.3% had sport irregularly, and 47.2% had no sport activity. The type of sport was walking (45.0%), callisthenic (22.0%) jogging/running (15.6%), badminton (6.5%), volley ball/soccer (4.1%), tennis (3.8%), and golf (0.1%). There was a significant difference in the prevalence of hypertension between people with heavy (12.0%), moderate (44.8%) and light work load (43.2%) (P<0.003), in the prevalence of hypercholesterolemia (13.2%: 50.8%: 36%) (P<0.0003), and smoking (19.7%; 44.1%: 36.2%) (P<0.00001), respectively. The difference also occurred in the prevalence of abnormal ECG (Q/QS, ST and T abnormalities) between people having regular sport (19.0%), irregular (22.7%), and no sport activity (58.3% (P<0.05). The number of respondents having enough physical activity (including regular sport) was relatively low. Therefore, promotion should be done as a preventive method to overcome cardiovascular risk factors. (Med J Indones 2001; 10: 34-41)

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
Pengaruh diet dan olahraga jalan cepat untuk mengendalikan tekanan darah laki-laki penderita prahipertensi
No full textThe objective of this study was to evaluate the effect of dietary approaches to stop hypertension for Indonesian at Jakarta (DASHI-J) and brisk walking exercise on the reduction of body weight and blood pressure of males prehypertension. A randomised clinical trial was conducted in Jakarta for 100 subjects, aged 25 – 55 years. Subjects were randomly assigned to a DASHI-J diet group (A), a brisk walking exercise group (B), a DASHI-J and brisk walking exercise group (C), and a control group (D). A and C groups received diet for lunch, snack and dinner five days a week for two months. The DASHI-J was given for lunch, snack, early dinner and 45 minutes brisk walking exercise for five days a week for two months. At the baseline, the mean of body weight, body mass index (BMI), visceral fat (VF), pulse pressure, blood fat, and blood electrolit were not significantly different among the four groups. After two months of intervension, the body weight, BMI, body fat, visceral fat, waist circumference, systole, diastole, and cholesterol serum of the groups reduce significantly (α<0.05). The highest reduction was in the DASHI-J and brisk walking exercise which reduced body weight 4.18 kg, BMI 1.50 kg/m2, and blood pressure 12.00/8.6 mmHg. This implies that DASHI-J and brisk walking exercise play a significant role in reducing body weight, BMI, systolic, and diastolic blood pressure
