Climate change and road safety: a review to assess impacts in Malaysia
No full textClimate change is very likely to cause a sharp increase in temperature, which in turn is likely to affect atmospheric water storage, and thereby the magnitudes, frequencies and intensities of rainfall. The road environment, including the weather factors is one of the major causes of accident across the world. Therefore, it is very certain that climate change induced changes in weather factors will affect road safety, if proper adaptation measures are not taken. The major objective of this article is to review the existing literatures on the influence of climatic variables on road accident in order to assess the possible impacts of climate change on road safety in Malaysia. The analysis of exiting literatures reveals that most imminent and certain impacts of climate change on road safety will be due to increase of temperature and rainfall related extremes. However, the impacts may not be very high in Malaysia due to moderate changes of those extremes over a long time. Any potential risk would be possible to mitigate by educating the people on possible impacts of climatic extremes on road environment and motivating them to change their driving behaviour during extreme weather events
Assessment of greenhouse gas emission reduction measures in transportation sector of Malaysia
No full textMalaysia has committed to reduce its greenhouse gas (GHG) emissions by up to 40% by the year 2020. The fact that transport sector of Malaysia shares a big portion of national GHG emissionsits role is paramount. The present study reviews the current state of GHG emission, the major technical and policy measures that can be adopted, and the measures that have been initiated in Malaysia for GHG emission reduction in transportation sector. Data related to road vehicles and GHG emission from road transportation are collected from open source databases and analyzed to reveal the present trends and possible future changes in GHG emission due to government initiatives. The result shows deceleration of GHG emission from transportation sector of Malaysia in recent years. However, the study reveals that the present measures may not be enough to reduce GHG emission up to the set target. Malaysia needs more prudent strategies for climate-friendly development of transportation to achieve sustainability goals. The study also examines the potential of Malaysia to reduce GHG and the measures that that can be initiated to streamline the effort towards GHG emission reduction are discussed
Spatial and temporal pattern of road accidents and casualties in Peninsular Malaysia
No full textRoad traffic accidents are often found to follow some spatial and temporal patterns as the factors that influence road accident changes with space and time. Knowledge on spatial and temporal variability of accident can be helpful for optimizing resources in order to improve traffic security management. The objective of the present study is to assess the spatial and temporal variation in the incidence of road traffic accidents and casualties across the states of peninsular Malaysia. Recent trends in number of accidents, casualties and fatalities are also accessed using non-parametric statistical method. The results show more accidents but lower fatalities in more urbanized and developed states, and lower accident levels but more serious fatalities in less urbanized or developed states of Peninsular Malaysia. Trend analysis reveals increasing number of accidents, but decreasing number casualties in recent years in most of the states of Peninsular Malaysia. The temporal analysis shows clear seasonal pattern in accident in some states of Malaysia. Most of the accidents are found to occur in festive month of Hari Raya Puasa festival followed by the month of mid-year school holiday. It is expected that the finding of the study will help in making recommendations in order to improve road safety and reduce road traffic accident in Malaysia
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
