THE IMPACT OF URBAN GROWTH ON REGIONAL DEVELOPMENT OF AKURE METROPOLIS, ONDO STATE, NIGERIA
Get PDFThe paper posits that the impact of urban growth could be understood from regional development perspective, using Akure metropolis, Ondo State, Nigeria as a case study. The first stage in the collection of primary data involves the reconnaissance survey of the study area, followed by the random administration of 25 questionnaires in each of the six identified quarters. Secondary data were also adopted, while data were descriptively and inferentially analyzed. The research revealed that one of the major causes of urban growth is employment opportunities, while the impact of urban growth on employment has not been satisfactory. The paper has found out that the impact of urban growth on economic activities was very good, whereas it was insignificant on infrastructural development. The research shows a fair impact of urban growth on health status, the paper also shows a positive relationship between urban growth and social vices. It was further revealed that the impact of urban growth on the standard of living and on the urban sprawl was fair and fairly significant respectively. The impact of urban growth on housing was not satisfactory. The paper shows that birth control measures could be adopted in mitigating the regional adverse effect of urban growth. It was further recommended that, in order to ensure urban tranquility, livability, socio-economic advancement and sustenance, government should create more employment, prioritizing increase in government expenditure and adequate security provision should be endeavoured
Industrial Agglomeration and Environmental Problems Severity Perception, in the Lagos Region, Nigeria
Get PDFDespite all the advantages derived from agglomeration economies, it also has negative effects. This paper therefore underscores the severity of these environmental problems (negative effects) arising as a result of industrial agglomeration.. Data were collected in two different stages; first was the reconnaissance of the study area and second was the questionnaire administration. Information on the severity of agglomeration impact measured through responses was obtained through a questionnaire survey administered to the heads of the household. The choice of heads of household was done through a spatial systematic sampling procedure; on the whole 120 individuals were covered. This sample was chosen to portray the relationship between firms distance and perception of environmental problems resulting from firms. The paper has found out the negative effects arising from agglomeration of firms, which includes: land pollution, vibration, irritating fumes, heavy traffics, overcrowding, noise pollution, increase in house rent and crime rate. The paper revealed that of the ten impacts indicated by the respondents, air and noise pollution were the most significant. The research also shows that the environmental problems were severe; there is a distant decay effect in the impact. A correlation analysis between the severity of impact and distance resulted in a value of minus 0.641 which is significant at 5 % level. It is however recommended that government should invest in the industrial sector and encouraged agglomeration
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
