Biodiversity Conservation and the Poor: Practical Issues beyond Global Conferences  [PDF]
Esther W. Dungumaro
Natural Resources (NR) , 2013, DOI: 10.4236/nr.2013.44040

The paper focuses on biodiversity—an issue that easily gets left out of consideration because it is hard to measure. While efforts to reduce over-fishing or conservation of water resources are relatively easy to discuss in quantitative terms, biodiversity in terms of plant species is usually covered by crude and even invalid figures. The paper begins by providing a brief historical overview of attempts to define biodiversity, going back to the early efforts in Africa to deal with conservation and showing how definitions have evolved overtime and how they have shaped conservation efforts. While the main focus of the paper is biodiversity conservation and the poor, the paper makes references to the World Summit on Sustainable Development (WSSD) and other important global conferences including the World Conference on Environment and Development and Convention on Biological Diversity. The paper finds that international conferences by and large do not adequately address the issue of biodiversity and the poor. The limited commitment shown by political leaders at the conferences should be a reason for global and local authorities to create an environment that enables communities to meet their daily needs, foster development and conserve biodiversity.


Economic Growth and Poverty: Pro-Poor Growth? In the Republic of Congo  [PDF]
Ngakoli Esther Victorie
Theoretical Economics Letters (TEL) , 2014, DOI: 10.4236/tel.2014.46059

Using a posterior approach from 2005 to 2011, this article seeks to answer the question: does economic growth benefit the poor or not in the Republic of Congo? The study found that across the country, the index of pro-poor growth has been positive and superior to one, which is indicative of pro-poor growth, but it is pro-rich in urban areas. However, the study conceals disparities in the regions due to the constraints of informational orders. The study recommends specific policy measures to increase, specifically household surveys in twelve regions in the Republic of Congo to better understand the extent of poverty.

Patterns of Technology Transfer in Chinese Hotspots of Innovative Development — The Perspective of the Recipient Firms  [PDF]
Henning Kroll, Esther Schnabl
Chinese Studies (ChnStd) , 2014, DOI: 10.4236/chnstd.2014.33012
Abstract: In China, as in other countries, pre-competitive research constitutes the basis of techno-economic development beyond imitation and adaptation. While acknowledging the nation’s concerted efforts to improve the situation, most empirical accounts of science-industry linkages in China remain sceptical about local universities’ ability to meaningfully transfer knowledge and technologies. Against this background, we change perspective and analyse the perceptions of selected technology-oriented firms in Beijing. Interestingly, we find that there is a notable core of technology firms with fairly close linkages to universities and research institutions.
In Vitro Antifungal Efficacies of Maize Associated Microorganisms  [PDF]
Esther Aanuoluwa Ekundayo, Bolatito Esther Boboye, Fatusa Clement Adetuyi
Advances in Microbiology (AiM) , 2015, DOI: 10.4236/aim.2015.54024
Abstract: Microorganisms (bacteria and fungi) were isolated from different parts of yellow maize (stem, cob, husk, leaf, root) as well as from rhizosphere and non-rhizosphere soil of maize using conventional microbiological techniques. A total number of twenty-six bacteria and thirteen fungi were isolated. The antagonistic efficacies of these isolates were tested against Sclerotium rolfsii, Aspergillus repens, Penicillium notatum and Pythium sp. using streak bioassay, food poisoning and dual culture techniques. None of the bacteria was antagonistic to the test fungi at 25°C on PDA using streak bioassay. However, there was reduction in the population density of the test fungi using food poisoning technique. The fungal isolates were antagonistic to the test fungi in varying degrees. Generally, S. rolfsii was susceptible to seven out of the eight fungal antagonists while P. notatum was least susceptible. The percentage reduction of S. rolfsii ranged from 40.00 ± 5.78 to 64.07 ± 2.31. Efficacies of chemical fungicides; mancozeb, camazeb and red force at 3 different concentrations— 0.05%, 0.1% and 1.0% (w/v) on the test fungi were also determined. No growth of the test fungi was observed at 1% (w/v) of all the fungicides while at lower concentration (0.05%), red force did not have any inhibitory effect. The growth of S. rolfsii was completely inhibited at 0.05% of mancozeb whereas there was reduction in mycelial growth of A. repens. Effect of inoculation time and nutrients (PDA and MEA) was determined on the antagonistic activities of Trichoderma viride. There were significant differences in inhibitory potentials of the two isolates of Trichoderma viride when pre-inoculated on the culture medium. The antagonistic potentials were more pronounced on malt extract agar than potato dextrose agar.
Optimizing the Physical, Mechanical and Hygrothermal Performance of Compressed Earth Bricks
Esther Obonyo
Sustainability , 2011, DOI: 10.3390/su3040596
Abstract: The paper is based on findings from research that assesses the potential for enhancing the performance of compressed earth bricks. A set of experiments was carried out to assess the potential for enhancing the bricks’ physical, mechanical and hygrothermal performance through the design of an optimal stabilization strategy. Three different types of bricks were fabricated: soil-cement, soil-cement-lime, and soil-cement-fiber. The different types of bricks did not exhibit significant differences in performances when assessed on the basis of porosity, density, water absorption, and compressive strength. However, upon exposure to elevated moisture and temperature conditions, the soil-cement-fiber bricks had the highest residual strength (87%). The soil-cement and soil-cement-lime bricks had residual strength values of 48.19 and 46.20% respectively. These results suggest that, like any other cement-based material, compressed earth brick properties are affected by hydration-triggered chemical and structural changes occurring in the matrix that would be difficult to isolate using tests that focus on “bulk” changes. The discussion in this paper presents findings from a research effort directed at quantifying the specific changes through an analysis of the microstructure.
Safari tipográfico: Gráfica y tipografía popular de las calles de Santiago de Chile.
ARQ (Santiago) , 2002, DOI: 10.4067/S0717-69962002005000016
Abstract: from her foreign point of view, the author has made a research about traditional chilean sign painters. displaced progressively by digital graphic media and cut and paste techniques, this craft fights in order to survive: it is time to appreciate the value of these procedures and their influence in chilean popular graphics, before it is too late
Violência e pobreza no cinema brasileiro recente: reflex?es sobre a idéia de espetáculo
Hamburger, Esther;
Novos Estudos - CEBRAP , 2007, DOI: 10.1590/S0101-33002007000200011
Abstract: the article analyses recent works of fiction or non-fiction that made more visible the visual presence of the poor, black, dwellers of slums and neighborhoods in the periphery in brazilian television and cinema. when they bring the subject to public attention, these movies have intensified and stimulated a quarrel for the control of the visuality, for the definition of which subjects and characters will have audiovisual expression, how and where, which is an strategic element in the definition of contemporary order (or disorder).
La Psicología Ambiental y el desarrollo sostenible. Cual psicología ambiental? Cual desarrollo sostenible?
Wiesenfeld, Esther;
Estudos de Psicologia (Natal) , 2003, DOI: 10.1590/S1413-294X2003000200007
Abstract: this article raises some reflections on some approaches to sustainable development (sd) and on the contributions environmental psychology (ep) can make in order to promote sustainable communities, in the latin american context. for this purpose: a) some of the proposals for sd, formulated in various contexts and disciplines, are analysed in terms of the place they assign to the psychosocial dimension and the way they deal with it, b) some of the theoretical approaches and methodological strategies which, in general terms, have oriented professional practice in ep are briefly described on the basis of their potential contributions for a sd in our continent, c) some considerations on the requirements for an ep oriented towards producing relevant knowledge for sd are outlined. finally, and taking as example the articulation between urban unplanned settlements and the "formal city", some of the challenges and requirements for a model of sd, based on the principles suggested for an ep oriented towards promoting sustainability are pointed out.
Entre la invasión y la consolidación de barrios: análisis psicosocial de la resistencia al desalojo
Wiesenfeld, Esther;
Estudos de Psicologia (Natal) , 1998, DOI: 10.1590/S1413-294X1998000100003
Abstract: in the present paper we will illustrate some of the processes by which the habitants of a "barrio" are simultaneously subject to practices of inclusion and exclusion coming from the state policies. this generates contradictions in the backbone of the official institutions same as in the habitants exposed to such policies. we will analyze, stemming from a case study, strategies employed by the habitants for facing the threats of displacement to which they see themselves constantly exposed and we will suggest that the solutions to housing problems conducted and solved by the citizens themselves, pose among other things, the dilemma between necessity and legality.
Telenovelas e interpreta??es do Brasil
Hamburger, Esther;
Lua Nova: Revista de Cultura e Política , 2011,
Abstract: over the last forty years, soap operas - primetime series exhibited six times a week, targeting an imagined predominately female audience, but watched, in their most popular phase by a 40% male audience - have become a privileged niche for the interplay of interpretations of brazil. a complex web of relationships involves the authoritarian military agenda (1964-1984); advertisers agenda; and left-wing screenwriters, actors and directors coming from cinema and theater. filmed as they go on air, soap operas captured and expressed at least three different interpretations of a country undergoing rapid structural changes. the principal aesthetic conventions of the genre fueled rival broadcasting companies to propose three views of the country. from 1969 on, in tune with a brazil envisioned for the future, rede globo's soaps revolved around the dramas accompanying urbanization, social differences, the liberalization of conjugal relationships, and consumerism. in 1990, manchete tv proposed the re-interpretation of the country centered on the exotic landscapes found in the pantanal region, in the "heart of brazil". in 2006, following film approach to poverty and violence, record network introduces the favela scenario and the threats represented by drug trafficking.
