Interdependence in social and territorial planning theories and sustainable development principles
This paper intends to deal with interdependence relationships between social and planning theories and their environment principles in a context of a sustainable development. Within any community, people through their activities interact with the physical environment, giving to each region its characteristics and specificity. Then, the management of the activities and the environment needs regulations because the socially unsatisfactory outcomes of the development process give rise to the need of intervention of government. This intervention is enabled through the objectives and the implementation of development planning which, in context of sustainable development, will have to incorporate social and economic and natural environment requirements. Both the management and the planning are closely related in functional terms and complementary. Moreover, the environmental assessment will contribute to the improvement of the planning assessment by integrating the output into development planning and the development control decisions. All this requires a systematic approach to deal with some regional problems of development and of environmental protection. But potential conflicts between the objectives of management and planning or between development and environment principles, can occur
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
Déterminants socio-économiques de l’utilisation des engins et pratiques de pêche destructives des ressources halieutiques sur le lac Toho au Bénin (Afrique de l’Ouest)
La pêche est une activité importante qui contribue à la sécurité alimentaire dans le monde entier, en particulier dans les pays en développement. Elle représente l’une des activités principales dans le septième Pôle de Développement Agricole au Bénin. Elle constitue pour les populations locales non seulement une source de protéines animales hautement nutritives mais aussi une activité génératrice de revenus. Elle est l’une des principales activités humaines qui affectent les écosystèmes aquatiques. L’objectif de cette étude était d’analyser les déterminants socio-économiques de l’utilisation des engins et pratiques de pêche destructives des ressources halieutiques. L’étude a porté sur 129 pêcheurs dans les villages Vèha et Logbo (commune de Lokossa) et Tokpa et Tohonou (commune de Houéyogbé). La méthode d’échantillonnage aléatoire simple a été utilisée pour la sélection des unités d’enquête. Un modèle Logit binomial a été utilisé pour l’analyse des déterminants socioéconomiques. Les résultats de l’étude ont montré que le nombre d’années d’expériences dans la pratique de la pêche, le niveau d’instruction du pêcheur et la fréquence de pêche sont les déterminants de l’utilisation des engins et pratiques de pêche destructives des ressources halieutiques au niveau du lac Toho. L’utilisation des filets réglementés, le développement d’activités génératrices de revenus autres que la pêche, la réduction de la pêche à la main, la réduction de l’utilisation des épuisettes et le développement de la pisciculture sont des stratégies de gestion développées par les pêcheurs face à la baisse des ressources halieutiques dans le lac Toho.Mots clés : Ressources halieutiques, déterminants, engins et pratiques de pêche, modèle logit binomial.
English Title: Socio-economic determinants of the use of destructive fishing gear and practices of fishery resources on Lake Toho in Benin (West Africa)Fishery is an important activity contributing to food security in the world and particularly in developing countries. In south of Benin, fishery is one of the main activities in coastal regions. Fishery is not only a source of protein with high nutritious value but also an income generating activity. It is one of the main human activities which affect aquatic ecosystem. This study aims at analyzing the socio-economic determinants of the use of the destroy engine and practical in fisher. A total of 129 fishermen were interviewed in Vèha and Logbo villages in the district of Lokossa and Tokpa and Tohonou villages in the district of Houéyogbé in South of Benin. A simple random sampling was used for selecting the survey units. Binomial Logit model was used to analyze the data. The results revealed that the number of years in fishery activity, the level of education and the frequency of fish harvesting are the socioeconomic determinants of the use of destroy practical in fishery in Toho lake. The use of regulated nets, the development of income-generating activities other than fishing, the reduction of catching fish by hand, the development of aquaculture and the development of the ritual practices, are ways to cope with the decline in halieutic resources of the fishermen.Keywords: Fishery resources, determinants, fishing gear and practices, Binomial Logit model
Dispelling the Myths Behind First-author Citation Counts
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
Déterminants Des Montants De Consentement À Payer (CAP) Déclarés Par Les Ménages Pour Une Gestion Durable De La Forêt d’Adjamey Au SudOuest Du Bénin
The objective of this study is to analyze the factors that explain the amounts of willingness to pay (WTP) of households for the implementation of a sustainable management program of Adjamey forest in the district of Djakotomey in South-West of Benin. Indeed, the bordering populations of this forest are frequently faced with the problem of the devastation of their crops by the hippopotamuses. These in turn undergo anthropological actions causing the continued loss of their habitat. The data were collected on 110 bordering households using a semi-structured questionnaire. Based on the two-step selection model of Heckman, this study revealed that the households participation to the program of sustainable management of this forest is influenced by factors such as: the origin and level of education of the surveyed households, the fact of having been victims of the damage caused by the hippopotamuses and the fact that the household wishes an improvement of the management of this forest. Moreover, the study shows that the total area held in the forest, the total income drawn from the activities related to the forest, the membership in a management committee and the fact that the hippopotamuses are considered as a threat constitute to the explanatory factors of the amounts of willingness to pay (WTP) declared by the households
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
