University Recreational Facilities Service Quality and Students’ Physical Activity Level
No full textAbstractService quality of recreational facilities is an important factor in attracting people to get involved in physical activities such as fitness training, outdoor recreation and sports. This study aims to examine the relationship between university recreational facilities service quality and students’ physical activity level. 390 university students (n = 390) from Universiti Teknologi MARA, Universiti Tenaga Nasional and National Defence University of Malaysia participated in the study. The instruments used were International Physical Activity Questionnaire-Short Form and Service Quality survey. The questionnaire used was based on three main dimensions that represented service quality, namely, ambience of the facility, operations quality and competency of the staff. The items were measured using the Likert scale in which one (1) represented ‘poor’ and five (5) represented ‘excellent”. The overall service quality was measured by calculating the mean score for each dimension and the grand mean of all items. The data was analyzed using Spearmen Correlation. The findings indicated that there was no significant relationship between service quality and physical activity level p = 0.312 (p > 0.05). Thus, service quality did not affect the level of physical activity of the students. However, there was evidence indicating that the universities were still lacking in recreational facilities and quality operation - factors that could attract the students to be physically active
Going 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
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
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
Optimisation of kitchen waste composting
Get PDFThe problems of limited spaces for new opening of landfills and shortened life span of existing landfills have encouraged moves to reduce the amount of waste sent to landfills nationwide. Composting is a good recycling method to fully utilise all the organic materials from kitchen waste as it contains high nutritious matter within the waste. Optimisation of kitchen waste mixture proportions containing vegetable scraps, fish processing waste and newspaper or onion peels were investigated to find the optimum initial moisture content and carbon-to-nitrogen (CN) ratio to commence a more effective composting process. By applying the simplex-centroid mixture design method using a commercial software, the best mixtures proportion for blend with newspaper was at 48.5% of vegetable scraps, 17.7% of fish processing waste and 33.7% of newspaper, while for blend with onion peels, was at 44.0% of vegetable scraps, 19.7% of fish processing waste and 36.2% of onion peels to produce desired initial moisture content of 60% and CN ratio of 30. Utilising the optimal mixture proportions, following composting studies were conducted. The evaluation of the performance of the composting process was through measurements of CN ratio while monitoring its changes in temperature, moisture content, volatile solids content, pH, electrical conductivity, bulk density, colour, microbial numbers, headspace oxygen and carbon dioxide content. A kitchen waste composter which enables controlled composting conditions was designed and fabricated. It allows control of temperature inside the composter by either switching on or off a bulb attached on top of composter, and for control of moisture content of composting materials, the small holes at the bottom of the composter allows excessive water to flow out and then collect from the underside of the composter. The composter is insulated with 2 mm thickness of cloth to reduce the heat loss. The effects of using two bulking agents, newspaper and onion peels in kitchen waste composting were investigated by creating parallel composting using two kitchen waste composter. The optimum kitchen waste mixture compositing was used for a composting process of 30-days where temperature profiles were recorded and the CN ratio measured as indication of compost maturity. It was found that blends with onion peels decomposed more quickly than the newspaper, which by 30-days of composting period, the blends with onion peels produced end product with CN ratio of 8.15, while the newspaper with CN ratio of 37.04 and did not achieve any thermophilic stage. The results suggest that the onion peels are more suitable and the newspaper did not assist in acceleration of the composting process. The effects of kitchen waste compost load size were then investigated using kitchen waste mixtures with onion peels at 2 and 6 kg. The smaller load, 2 kg, decomposed more rapidly than the 6 kg because the temperature decreased to mesophilic temperature was 10 days earlier than in 6 kg and the CN ratio of 2 kg reaching 15 at 8 days earlier than 6 kg. Although the 2 kg of waste undergone shorter time of thermophilic phase at time range of about 3 days, it was still sufficient to kill the pathogens. This experiment suggests that a 2 kg of kitchen waste is enough to commence such composting. In accelerating composting processes, the use of microorganisms as an accelerant for this kitchen waste composting tested at 6 kg of kitchen waste with onion peels blend. Microbes’ cocktail consisting a mixture of seven types of bacteria and eight types of fungi priory isolated from soil, was added at the early stage of composting period in one composter while a control, a similar compost without adding the starter culture was compared. Analysis of variance (ANOVA) performed on the compost maturity indices did not show significant differences between the microbe added compost and control since p = 0.8158. The starter culture is therefore not necessarily to be added in the composting of food waste. In conclusion, composting of kitchen waste can be made simple and efficient with the right mixture proportion and type of waste to begin, using a minimal load of about 2 kg and without additional accelerant microbes. The effort of recycling kitchen waste is important in helping to build a sustainable environment that promises balanced ecosystems
