Studio della Peste dei Piccoli Ruminanti nei territori saharawi

La Peste dei Piccoli Ruminanti (PPR) è una patologia virale ed acuta che colpisce i piccoli ruminanti, diffusa in Africa Sub-Sahariana, in Medio Oriente ed in Asia Meridionale. Questo lavoro si propone di effettuare il primo studio epidemiologico sulla PPR nella Repubblica Araba Saharawi Democratica (RASD), che comprende i Campi Profughi Saharawi, in territorio algerino, ed i “Territori Liberati” del Sahara Occidentale, valutando la potenziale presenza, prevalenza e distribuzione del virus della PPR in questi territori. Lo studio si è basato su una metodica di campionamento “a cluster” secondo la tecnica “a due stadi”. Sono stati individuati 23 siti di campionamento dai quali sono stati raccolti un totale di 976 campioni di siero prelevati da pecore, capre e cammelli. I campioni sono stati prelevati in Marzo ed Aprile 2008. I risultati dei test Competitive-Elisa hanno evidenziato una sieroprevalenza nel 28,26% degli animali testati, benché durante la raccolta dei campioni nessun animale abbia presentato sintomi clinici riferibili alla PPR. Tra Gennaio e Maggio 2010, in seguito ad episodi di aumentata mortalità nella popolazione ovi-caprina presente nei Campi Profughi, le autorità veterinarie locali sospettarono un outbreak di PPR. Tra Maggio ed Ottobre 2010 è stato sviluppato un outbreak investigation nei Campi Profughi Saharawi con lo scopo di confermare la circolazione del PPRV. I risultati di laboratorio hanno confermato la presenza del virus nel 33,33% dei campioni. Il sequenziamento del genoma virale ha rivelato che il virus apparteneva al Lignaggio 4 e le analisi filogenetiche hanno indicato una stretta relazione (99.3%) con il PPRV isolato durante l'epidemia di PPR in Marocco del 2008.

Sustainable improvement of water networks : to achieve best decisions for rehabilitation plans using advanced GIS and statistical techniques

Many of developing countries are facing crisis in water management due to increasing of population, water scarcity, water contaminations and effects of world economic crisis. Water distribution systems in developing countries are facing many challenges of efficient repair and rehabilitation since the information of water network is very limited, which makes the rehabilitation assessment plans very difficult. Sufficient information with high technology in developed countries makes the assessment for rehabilitation easy. Developing countries have many difficulties to assess the water network causing system failure, deterioration of mains and bad water quality in the network due to pipe corrosion and deterioration. The limited information brought into focus the urgent need to develop economical assessment for rehabilitation of water distribution systems adapted to water utilities. Gaza Strip is subject to a first case study, suffering from severe shortage in the water supply and environmental problems and contamination of underground water resources. This research focuses on improvement of water supply network to reduce the water losses in water network based on limited database using techniques of ArcGIS and commercial water network software (WaterCAD). A new approach for rehabilitation water pipes has been presented in Gaza city case study. Integrated rehabilitation assessment model has been developed for rehabilitation water pipes including three components; hydraulic assessment model, Physical assessment model and Structural assessment model. WaterCAD model has been developed with integrated in ArcGIS to produce the hydraulic assessment model for water network. The model have been designed based on pipe condition assessment with 100 score points as a maximum points for pipe condition. As results from this model, we can indicate that 40% of water pipeline have score points less than 50 points and about 10% of total pipes length have less than 30 score points. By using this model, the rehabilitation plans for each region in Gaza city can be achieved based on available budget and condition of pipes. The second case study is Kuala Lumpur Case from semi-developed countries, which has been used to develop an approach to improve the water network under crucial conditions using, advanced statistical and GIS techniques. Kuala Lumpur (KL) has water losses about 40% and high failure rate, which make severe problem. This case can represent cases in South Asia countries. Kuala Lumpur faced big challenges to reduce the water losses in water network during last 5 years. One of these challenges is high deterioration of asbestos cement (AC) pipes. They need to replace more than 6500 km of AC pipes, which need a huge budget to be achieved. Asbestos cement is subject to deterioration due to various chemical processes that either leach out the cement material or penetrate the concrete to form products that weaken the cement matrix. This case presents an approach for geo-statistical model for modelling pipe failures in a water distribution network. Database of Syabas Company (Kuala Lumpur water company) has been used in developing the model. The statistical models have been calibrated, verified and used to predict failures for both networks and individual pipes. The mathematical formulation developed for failure frequency in Kuala Lumpur was based on different pipeline characteristics, reflecting several factors such as pipe diameter, length, pressure and failure history. Generalized linear model have been applied to predict pipe failures based on District Meter Zone (DMZ) and individual pipe levels. Based on Kuala Lumpur case study, several outputs and implications have been achieved. Correlations between spatial and temporal intervals of pipe failures also have been done using ArcGIS software. Water Pipe Assessment Model (WPAM) has been developed using the analysis of historical pipe failure in Kuala Lumpur which prioritizing the pipe rehabilitation candidates based on ranking system. Frankfurt Water Network in Germany is the third main case study. This case makes an overview for Survival analysis and neural network methods used in water network. Rehabilitation strategies of water pipes have been developed for Frankfurt water network in cooperation with Mainova (Frankfurt Water Company). This thesis also presents a methodology of technical condition assessment of plastic pipes based on simple analysis. This thesis aims to make contribution to improve the prediction of pipe failures in water networks using Geographic Information System (GIS) and Decision Support System (DSS). The output from the technical condition assessment model can be used to estimate future budget needs for rehabilitation and to define pipes with high priority for replacement based on poor condition. rn

Feminist Tigers and Patriarchal Lions: Rhetorical Strategies and Instrument Effects in the Struggle for Definition and Control over Development in Nepal

This article offers an analysis of a struggle for control of a women’s development project in Nepal. The story of this struggle is worth telling, for it is rife with the gender politics and neo-colonial context that underscore much of what goes on in contemporary Nepal. In particular, my analysis helps to unravel some of the powerful discourses, threads of interest, and yet unintended effects inevitable under a regime of development aid. The analysis demonstrates that the employment of already available discursive figures of the imperialist feminist and the patriarchal third world man are central to the rhetorical strategies taken in the conflict. I argue that the trans-discursive or “borderland” nature of development in general and women’s development in particular result in different constructions of “development” goals, means and actors based not only on divergent cultural categories but on historically specific cultural politics. I argue further that the apolitical discourse of development serves to cloak its inherently political project of social and economic transformation, making conflicts such as the one that occurred in this case not only likely to occur but also likely to be misunderstood.

Can Developing Women Create Primitive Art? and Other Questions of Value, Meaning and Identity in the Circulation of Janakpur Art

In this article, I examine the values and meanings that adhere to objects made by Maithil women at a development project in Janakpur, Nepal – objects collectors have called ‘Janakpur Art’. I seek to explain how and why changes in pictorial content in Janakpur Art – shifts that took place over a period of five or six years in the 1990s – occurred, and what such a change might indicate about the link between Maithil women’s lives, development, and tourism. As I will demonstrate, part of the appeal for consumers of Janakpur Art has been that it is produced at a ‘women’s development project’ seeking to empower its participants. And yet, the project’s very successes threaten to displace the producers (and what they produce) from their perceived qualities/identities as ‘traditional’ and ‘primitive,’ thereby bringing into question the authenticity of the ‘art’ they produce. The conundrum begs this question: can developing women produce primitive art?

Pond-Women Revelations: The Subaltern Registers in Maithil Women's Expressive Forms

Ponds are ubiquitous in the Maithil region of Nepal, and they figure prominently in folk narratives and ceremonial paintings produced by women there. I argue that in Maithil women's folktales, as in their paintings, the trope of ponds shifts the imaginative register toward women's perspectives and the importance of women's knowledge and influence in shaping Maithil society, even as this register shift occurs within plots featuring male protagonists. I argue further that in the absence of a habit of exegesis in their expressive arts, and given the cross-referential, dialogic nature of expressive practices, a methodology that draws into interpretive conversation the multitude of expressive forms exercised by Maithil women enhances analytical access to Maithil women's collective perspectives on their social and cosmological worlds.

Talking Tools, Suffering Servants, and Defecating Men: The Power of Storytelling in Maithil Women’s Tales

What can we learn about the way that folk storytelling operates for tellers and audience members by examining the telling of stories by characters within such narratives? I examine Maithil women’s folktales in which stories of women’s suffering at the hands of other women are first suppressed and later overheard by men who have the power to alleviate such suffering. Maithil women are pitted against one another in their pursuit of security and resources in the context of patrilineal formations. The solidarities such women nonetheless form—in part through sharing stories and keeping each other’s secrets—serve to mitigate their suffering and maintain a counter-system of ideational patterns and practices.

'Listen, Rama’s Wife!’: Maithil Women’s Perspectives and Practices in the Festival of Sāmā-Cakevā

As a female-only festival in a significantly gender-segregated society, sāmā cakevā provides a window into Maithil women’s understandings of their society and the sacred, cultural subjectivities, moral frameworks, and projects of self-construction. The festival reminds us that to read male-female relations under patriarchal social formations as a dichotomy between the empowered and the disempowered ignores the porous boundaries between the two in which negotiations and tradeoffs create a symbiotic reliance. Specifically, the festival names two oppositional camps—the male world of law and the female world of relationships—and then creates a male character, the brother, who moves between the two, loyal to each, betraying, in a sense, each, but demonstrating, by his movements, the currents and avenues of power. This article makes available to other scholars of South Asian culture and society an extended description and analysis of this distinctive festival, while also contributing to the scholarly discussion of women’s expressive traditions.

The Politics of Purchasing Power: Feminist Tourism and Women's Development in Nepal

My purpose in this essay is to explore how ideas about women and development are created and circulated at the moment of consumption of wares produced at a women's development project in Nepal. I analyze the project as an example of the ways that women's development is an object of material and discursive consumption. Artifacts produced and sold by Nepali women, and purchased by tourists from the "first world," become part of an international exchange of power, money, and meaning. Based on a survey of consumers and ethnographic observations, I conclude that feminist tourists forge relations with disempowered "Others" through the pleasurable activity of an alienated market transaction. Consumers of crafts produced at a women's development project assume a position of empowerment and enlightenment, ready to help out their "women" counterparts through their support of an enterprise with circular logic: within the industry of development (although not necessarily for feminist tourists themselves), at least one of the central projects of development is the development project itself. At the same time, feminist tourists locate themselves outside the oppressive structures and ideologies affecting their "third-world sisters." This is a relation of sympathy and imagined empathy, with no sense of differential location within systems of oppression. They fail to examine or articulate the global link between their own purchasing power and local living conditions of Maithil women; the connection is effectively built out of the discourse.

Narrating Boundaries: Framing and Contesting Suffering, Community, and Belonging in Enclaves along the India-Bangladesh Border

This paper explores the politics of community making at the India-Bangladesh border by examining the public and private narratives of history and belonging in a Bangladeshi enclave-a sovereign piece of Bangladesh completely territorially surrounded by India. Drawing on framings of political society, this paper argues that understanding populations at the margins of South Asia and beyond requires attention to two processes: first, to the ways that para-legal activities are part and parcel of daily life; and second, to the strategies through which these groups construct themselves as moral communities deserving of inclusion within the state. Border communities often articulate narratives of dispossession, exceptionality, and marginalization to researchers and other visitors-narratives that are often unproblematically reproduced in academic treatments of the border. However, such articulations mask both the complicated histories and quotidian realities of border life. This paper views these articulations as political projects in and of themselves. By reading the more hidden histories of life in this border enclave, this article reconstructs the notion of borders as experienced by enclave residents themselves. It shows the ways that the politics of the India-Bangladesh border are constitutive of (and constituted by) a range of fractures and internal boundaries within the enclave. These boundaries are as central to forging community-to articulating who belongs and why-as are more public narratives that frame enclave residents as victims of confused territorial configurations.

Recent increase in black carbon concentrations from a Mt. Everest ice core spanning 1860-2000 AD

A Mt. Everest ice core spanning 1860–2000 AD and analyzed at high resolution for black carbon (BC) using a Single Particle Soot Photometer (SP2) demonstrates strong seasonality, with peak concentrations during the winter-spring, and low concentrations during the summer monsoon season. BC concentrations from 1975–2000 relative to 1860–1975 have increased approximately threefold, indicating that BC from anthropogenic sources is being transported to high elevation regions of the Himalaya. The timing of the increase in BC is consistent with BC emission inventory data from South Asia and the Middle East, however since 1990 the ice core BC record does not indicate continually increasing BC concentrations. The Everest BC and dust records provide information about absorbing impurities that can contribute to glacier melt by reducing the albedo of snow and ice. There is no increasing trend in dust concentrations since 1860, and estimated surface radiative forcing due to BC in snow exceeds that of dust in snow. This suggests that a reduction in BC emissions may be an effective means to reduce the effect of absorbing impurities on snow albedo and melt, which affects Himalayan glaciers and the availability of water resources in major Asian rivers.
