Thermal Impacts of the Internal Courtyards in Compound Houses: The Case of Tamale Metropolis
No full textThe research seeks to understand the effects of internal courtyards onthermal comfort conditions in compound houses in Ghana’s TamaleMetropolitan area. Internal courtyards are an integral part of the design ofcompound houses in this location.Their inclusion in building designs is largely as a point of domestic activitysuch as cooking and cleaning and also for social interaction. However, a lotof interchanges in thermal conditions between structures and the outdoorstake place within these internal courtyards. Various design details of thebuilding will engender different thermal responses of the internal courtyard.This paper assesses thermal comfort in compound houses as againstbungalow type houses in the Tamale Metropolis, Ghana by the applicationof the Predicted Percentage of Dissatisfied Persons (PPD) and PredictedMean Votes (PMV) model. This prototype compares with the InternationalStandards Organization (ISO) 7730 and American Society of Heating,Refrigeration and Air-Conditioning Engineers (ASHRAE) Standard 55(estimated values between 23˚C - 26˚C seen as the allowable temperatures).Ambient indoor conditions (dry bulb temperature and relative humidity)of five (5) buildings each from the two building typologies from wererecorded over a period of ten calendar months. These ambient conditionswere analyzed, consequently generating the Predicted Percentage ofDissatisfied Persons (PPD) and Predicted Mean Votes (PMV) recordings.The investigations uncovered relatively high PPD - PMV recordingsrelating to the Bungalow type buildings while the compound housesattune to the comfort zone. The Actual Mean Votes (AMV) of residentssuggests the two building typologies are all rated comfortable however; thecompound houses are rated above the bungalow type houses
Comprehensive Investigation into the Menace of Roof Collapse in Tamale and the Way Forward
No full textThere is a perpetual problem of partial or complete roof collapse withinthe Tamale Metropolis and other parts of Ghana. This has become an issueof grave public concern since this menace affects both public buildingsof all kinds (schools, offices, churches, mosque etc.) as well as domesticbuildings.This research sets out to conduct comprehensive investigations into thenature of roof failures, causes, and effects and then propose remedialactions towards stemming the tide.The study employed the use of roof construction affirmation surveys,questionnaires, interviews and focus group discussions. Relevantinformation synthesized indicates that the roof type, construction materials,building type and environmental conditions are crucial causative factors.Major consequences of roof failures include damage to personal belongingsand exposure to inclement weather conditions, the psychological traumavictims are subjected and pressure on incomes and living conditions as aresult of the cost of repair or replacement of the roofs.It is recommended that expert advice be sought in checking maintenancerequirements of existing roofs in the study area and also during the designand construction of new roofs. Tree planting programmes for this heavilydeforested region should be encouraged. The use of green timber for roofconstruction must be replaced with well-seasoned ones. Proper constructiondetailing and placement openings buildings should be done so that windflow during a windstorm is optimized
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
