Spatio-temporal trends of typhoid fever among youths attending Muhammad Abdullahi Wase Specialist Hospital in Kano Metropolis, Nigeria
Full text linkTyphoid fever continues to be significant causes of illness and death particularly among children and adolescents in developing countries as a result of poor sanitation and unsafe food and water supply especially where the water is contaminated by human feces. This study analysed the spatial and temporal trends of typhoid fever in Kano metropolis between 2010-2014. Hospital records for youths attending Muhammad Abdullahi Wase Specialist Hospital (MAWSH) were used. Coordinate of wards in the metropolis was also generated and imported into Arc GIS environment. G-Statistics was used to determine the distribution and cluster of typhoid prevalence. The results showed an upward trend with increase in age. It also showed a downward trend from 2010 to 2014, indicating that people are becoming aware of the disease and the predisposing factors. The findings also revealed higher prevalence among the males. The results of the G- Statistics showed higher prevalence in the northern part of the metropolis, with hot spots in Dakata and Tarauni wards. The study recommends frequent vaccination and good eating and drinking habits as well as good hygienic practices at home and outside home as remedies for addressing the problem.Keywords: Typhoid Fever, Spatial, Temporal, Youths, G-statistics, Kan
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
The status of integration of BIM into the curricula of construction education in Nigeria
No full textThis research appraises the status of BIM integration in the Curricula employed for training construction professionals in the Nigerian Construction industry. Using qualitative research approach, semi-structured interviews were conducted to the sample of nine (9) Construction Engineering and Management (CEM) programs offered in four tertiary institutions in Kaduna State. The heads of department of Architecture, Building and Quantity Surveying in these institutions were invited to participate in the survey. Data collected through the interviews were subsequently analysed using content analysis. The study found that although BIM is yet to be fully integrated into the curricula of the CEM programs of the surveyed institutions, the institutions have a fair awareness of the concept of Building Information Modeling and the potential benefits of its implementation in the industry. Also, several barriers such aslack of room in the existing curriculum for additional classeslack of staff with the knowledge of BIMhigh cost of trainin
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
