Logistic Challenges in Urban Waste Management in Ghana (A case of Tema Metropolitan Assembly)
Get PDFWaste handling is one of the greatest challenges facing humankind in modern times in spite of the numerous technological advancements that the world has experienced in recent times. The issue of waste management is a major problem confronting Ghana with detrimental effects on the nation’s economy, health of the citizenry and the social standing of the nation among community of nations. This problem is of keen concern to Ghana, particularly when it is clear that Ghana is one of the nations in South Saharan African with the potential of becoming a major tourism destination to many nationals the world over. The study therefore sought to identify the logistical issues that confront the most industrious metropolis of Ghana - the Tema Metropolitan Assembly (TMA), in the management of waste within the metropolis. The researchers employed a combination of simple random and purposive sampling techniques to conduct cross sectional survey on 182 samples during the conduct of the study. The study found that waste management companies operating within the metropolis seriously lack the desired logistics to execute their mandates of ensuring a clean city. The study further established inadequacy of household waste collection bins as the key logistics that the waste management companies lacked. This therefore prevents households from separating waste into the various components for easy management. Food debris, plastic solid waste, paper waste, bottles, cans/metals as well as old clothes were the main waste generated in the TMA. The study concludes that there is a general lack of key logistics (waste collection bins, trucks and site technologies) to manage waste in the Tema Metropolitan Assembly.

Women in Management: “Women Their Own Enemies?” A Study of Formal Sector Organizations in Ghana
Get PDFThe objective of this study is to investigate the common slogan that, “Women are their own enemies”, and unravel the factors contributing to this perception within the context of formal sector employment as it relates to women’s ambition in climbing the corporate ladder to the top. 200 structured questionnaires were administered to employees in 20 well established formal sector organizations, all of which have been in existence for at least two decades. Respondents include male and female employees of both management and subordinate status. Findings negate the assumption that women are not interested in top management positions and so are not projecting themselves and applying for the positions. It, however, revealed that female managers often sabotage other female management aspirants through severe criticism and failure to project them as good management candidates. Findings in this regard cannot, therefore, rule out the perception that women are their own enemies and for that matter contributing towards their paucity in top management positions.

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
