Assessment of Lean Construction Adoption Level to TETFund-Sponsored Construction Projects in Tertiary Institutions in Ekiti State, Nigeria
Full text linkThe construction industry plays a significant role in long-term national development and economic progress, most especially for emerging nations. The construction industry produces waste in terms of time and other resources to the tune of 57%. This enormous waste contributes greatly to inefficiency, high cost of production and eventually to low productivity. This brought about the concept of lean construction (LC) principles and its adoption. This study therefore seeks to examine the level of adoption of lean construction practices in the Nigerian construction industry, particularly within the context of public tertiary education infrastructure. The data used for this study was obtained through the administration of questionnaires to elicit responses from the target respondents. Data were analyzed using frequency, percentages and Relative Importance Index (RII) to measure the level of importance of various factors. The study revealed that the majority of the respondents was aware of and adopted lean construction and this eventually resulted in high-quality work output and elimination of waste on site. These findings underscore the importance of integrating lean methodologies at every stage of construction. The findings of this study will also provide valuable insights for researchers, policymakers, practitioners, and stakeholders, enhancing their understanding of the adoption of lean construction principles and identifying research gaps. A further study that can review the level of the adoption of lean construction using a wider scope in term of number of target respondents and not limited to only TETFund-Sponsored construction projects that can give a clearer picture is therefore recommended
PERFORMANCE EVALUATION OF STATE SUBSIDIZED HOUSING SCHEME: A CASE STUDY OF OGUN STATE HOUSING PROJECTS
Full text linkThe problems of housing in Nigeria are enormous and complex, exhibiting apparent and marked regional differences. In most urban centres, the problem is not only restricted to quantity but also to the quality of available housing units and the environment. This study therefore evaluated the building performance of State Subsidized Housing Schemes in Ogun State and ascertained whether or not the public housing estates fulfil the initial design/goal of government and the needs of the users with regard to the occupants` satisfaction. The objectives of the study were to examine housing delivery process, evaluate the physical characteristics and conditions of the housing units, examine the socio-economic characteristics of the residents, ascertain factors which influence levels of residents’ expectations and satisfaction with the housing estates and compare the occupants` expectations of the housing units, with their housing experience in the estates.
The study obtained both primary and secondary data. Qualitative data was obtained from key management staff of (OPIC) by means of in-depth interview. Quantitative data was obtained through administration of questionnaires on 716 housing units based on purposeful sampling of ten existing low-income housing estates spread across the State. Descriptive and inferential techniques were used for the analysis.
The result of study showed a positive and significant correlation between age range (r=0.397), marital status (r=0.297), and household size (r=0.189), however, Socio economic status (r=-0.275), educational attainment (r=-0.213) and ownership status (r= -0.285) had negative, but significant correlations at 0.05 level of significance. The study concluded that most residents found their housing units satisfactory but at different levels of satisfaction based on the age, length of residency, marital status and educational level. It is thus recommended that public agencies for low-income housing should pay proper attention to the management of support and public facilities to enhance residential satisfaction of the inhabitants and also adopt a policy to build different sizes of units to cater for the needs of the residents with large families in order to enhance quality of life of the low-income urban community in the country
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
