    Ethiopian urban land allocation policy and its contribution to urban densification

    No full text
    Urban densification is considered as the best tool for efficient urban land utilization, containment, and minimizing urban development costs. It is also a widely accepted approach to mitigate shortages of urban land and urban sprawl. With this in mind, Ethiopia has adopted a standard-based urban land allocation policy. The policy relies on population size during the urban planning process to address issues related to sustainable urban development by increasing the densities of its urban areas. However, the impact of the existing urban land allocation policy on urban densification has not been investigated adequately. Thus, this study examines the contribution of existing urban land allocation policies to urban densification in Ethiopia. A mixed research approach was employed to achieve the objective of the study. The study revealed that the policy gives more attention to the immediate and tangible conditions than the efficient use of land resources. Therefore, it allocated an average of 223 square meters of land to each person for urban development. The study implies that the country's urban land allocation policy is ineffective in achieving the intended outcome of urban densification. Instead, coupled with uncontrolled urban population growth, it has been exacerbating the rapid horizontal expansion of urban areas. With the current trend of horizontal expansion of urban areas, the country's land resources is expected to be converted into a built-up environment within the next 127 years unless the policy is radically changed. Thus, this paper calls for revisiting the existing urban land allocation strategy of the country in a way that responds towards efficient urban land allocation and sustainable urban development

    Evaluation of the urban Land use plan’s effectiveness in achieving resource efficiency: the case of Bahir Dar city- Ethiopia

    Urban land use plans (ULUPs) contribute to the efficient use of resources for sustainable urban development. However, the metered contribution of Bahir Dar’s ULUPs to the efficient use of resources has not yet been known. Bahir Dar is the capital of the Amhara Region and a scenic city on the southern shore of Lake Tana, Ethiopia’s largest lake and the source of the Blue Nile. It attracts many visitors from inside and outside the country. This study evaluates the effectiveness of ULUPs in Bahir Dar to achieve efficient use of resources such as water, energy, and food. Thus, the study developed criteria to assess the effectiveness of ULUPs based on the global indicator framework for the Sustainable Development Goals (SDGs). The results show that its ULUPs were not resource efficient in terms of food production, water quality and yield, and transport energy usage

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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 PDF
    We 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

    EXPECTATIONS AGAINST PRE-CONSIDERATIONS ON QUALITY OF URBAN LAND USE PLAN: THE CASE OF AMHARA REGION- ETHIOPIA

    Get PDF
    As the urban land use plan is a tool for urban land governance, this paper explores customers’ expectations that the service providers have not considered as the quality during urban land use plan preparation in Amhara Region - Northern Ethiopia. The study was conducted on 90 urban areas of the Amhara regional state who made the formal complaint against the quality of their urban plan in the year of 2017/18 (2010 Ethiopian calendar). Data were collected by means of the survey using questionnaires and document review. Then focused group discussions were made on the identified quality issues on land use plan presented by customers. The study identified six major types of quality disapprovals on the urban land use plan. Inappropriate strategies and difference in understanding of concepts of land use plan preparation are the two identified major causes or gaps, emanated from the service providers, for the customers’ dissatisfaction

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    We 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
