Breakfast skipping and its associated factors among undergraduates in a public university in Kuala Lumpur
No full textGoing Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Cardiovascular risks among shift and non-shift workers in a public medical centre in Kuala Lumpur
No full textNight work and rotating shift work are found to be detrimental to the health of workers. A cross sectional analytical study was conducted among the employees of a public medical centre in Kuala Lumpur. A total of 380 employees participated in the health screening and questionnaire survey. The majority of the respondents were Malays, females, and with mean age of 49 years old. The shift workers persistently had higher but non-significant proportions of being overweight/obesity and unhealthy clinical indicators such as systolic and diastolic blood pressure, fasting blood glucose and lipid profile except waist circumferences and HDL-cholesterol. There were also slightly more shift workers diagnosed with diabetes mellitus, hypertension or coronary heart disease (p>0.05). Although the present study could not provide established evidence for a relationship between shift work and cardiovascular risks, this could serve as a pilot study for future studies in this area
Framingham risk scores and anthropometric measurements in predicting cardiovascular risks among Malay men
No full textFramingham Risk Scores is an established method to predict an individual\u27s 10-year risk for coronary heart disease (CHD). It provides a more precise delineation of risk which might lead to appropriate selection of therapy and opportunities for patient education and motivation. A Healthy Lifestyle Project was initiated to decrease the modifiable risk factors for CHD in a worksite in Kuala Lumpur. The participants were Malay men (n=186) working as security guards in a public university. Their mean age was 46.6 + 6.6 years. The majority had secondary education and were married. The participants\u27 10-year risks based on the Framingham Risk Scores were 55.4%, 39.8% and 4.8% respectively for categories of low (20%) risk. Their Framingham Risk Scores were then correlated with anthropometric measurements such as the Body Mass Index (BMI), waist circumference and waist-hip-ratio (WHR). All the anthropometric measurements had weak but significant correlation with the Framingham Risk Scores (WHR: r=0.26waist circumference: r=0.23BMI: r=0.16). In conclusion, 44.6% of our participants had more than 10% risk in developing CHD in the coming ten years. Hence, they are suitable target candidates for the promotion of a healthy lifestyle such as smoking cessation, weight control, healthy dietary patterns and increased physical activities. Indicators of abdominal obesity like WHR or waist circumference may be used to complement the Framingham Risk Scores for the prediction of CHD risk in this population
Perceived risks, barriers and stages of change on smoking cessation among The Malay security guards in a public university in Kuala Lumpur.
No full textIntroduction: The objective was to evaluate the perceived risks, barriers and stages of change on smoking cessation among the Malay male security guards. Materials and Methods: In the year 2004, a cross sectional survey was conducted on a group of security guards working in the campus and the hospital of a public university in Kuala Lumpur. Universal sampling (n=210) was conducted with a response rate of 88.6%. A self-administered questionnaire was used to survey the participants on their smoking status, stages of change, perceived risks and barriers to smoking cessation. Results: There were 37% current smokers and 23.7% ex-smokers. The mean year of smoking was 19.2 + 8.1 and the number of cigarettes smoked was 16.4 + 8.0 per day among the current smokers. About two-third of the smokers perceived the amount smoked currently was bad for health. However, only 23.3% and 30.9% of the smokers perceived themselves to be at higher risk for lung cancer and heart disease respectively. The three main reasons to quit smoking were health reasons, doctorsâ advice and cost. The main barriers were addiction (53.3%) and stress (28.3%). Most of the smokers (42%) were in the pre-contemplation stage with half of them not having thoughts of quitting. Conclusion: The smokers had misperception on smoking and majority was at the pre-contemplation stage of change in smoking cessation. The findings of this survey add on to the existing literature about the perception of risks, barriers and stages of change to smoking cessation. This will provide valuable information on the planning and delivering of smoking cessation programmes in the local context
Factors influencing the uptake of pap smear screening among malay women in a public university in Kuala Lumpur - a pilot study
No full text596.36), older age (OR: 1.12, 95% CI: 1.031.22) or perceived higher benefits of Pap smear (OR4.80, 95% CI: 1.1420.15)
were more lilcely to have undergone Pap smear screening. Measures in reducing barriers and educating the public on the benefits of Pap smear are strongly recommended
Variations on the Author
Get PDF“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
Get PDFWe 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
Get PDFWe 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
