The ecological and socio-economic role of Prosopis juliflora in Eritrea

In Eritrea findet eine rasche Verbreitung von Prosopis (juliflora) statt, die sich negativ auf die Naturresourcen als auch die sozio-ökonomische Lage der ländlichen Bevölkerung auswirkt. Die Landbevölkerung Eritrea's ist davon überzeugt, dass die Pflanze vor allem die Ernährungssicherung beeinträchtigt und will deshalb, dass sie ausgerottet wird. Die vorliegende Dissertation beschreibt die Auswirkung von Posopis auf lokale Öko- und Wirtschaftssysteme und zieht Vergleiche mit der diesbezüglichen Situation in anderen Ländern. Im Weiteren stellt sie einen Prosopis Management-Plan vor, dessen Ziel es ist, die zunehmende Verbreitung zu verhindern. Auch liefert sie eine Gegenüberstellung der Ansichten von wissenschaftlichen Experten einerseits und Bauern und Nomaden andrerseits. Sie zeigt auf, dass die weit verbreitete Annahme der Experten das Problem Prosopis durch ökonomische Nutzung ("eradication by utilisation") in Schach halten zu können, fraglich ist.

"Talking about Marriage ..." : Polizeiarbeit in Upper West, Ghana /// Arbeitspapiere / Institut für Ethnologie und Afrikastudien ; 102

Polizei in Afrika ist korrupt und schlecht ausgebildet und eine „Marionette“ der Regierungen − so das nicht nur im populären, sondern auch sozialwissenschaftlichen Diskurs vermittelte Bild. Eine ethnographische Perspektive, die Polizeiarbeit im Alltag beobachtet und auf die Interaktionsstrategien der Polizisten mit Klienten und ihre Deutungen und Selbstbilder fokussiert, erlaubt neue Einsichten in das alltägliche Funktionieren der Organisation. Die vorliegende Arbeit basiert auf einem dreimonatigen Aufenthalt in der domestic violence unit der Police Headquarters in der Upper West Region Ghanas. Sie zeigt unter anderem, wie die Akteure die Ausbildung zum Polizisten, Gehaltsfragen, Versetzungen, Geschlechterverhältnis und Beförderungen konzeptionalisieren und wo sie sich in ihrer Arbeitswelt positionieren. Die besondere Aufmerksamkeit der Arbeit gilt der Interaktion der Polizisten mit Akteuren außerhalb ihrer Organisation, den „Klienten“. Eine zentrale Erkenntnis ist, dass die Klienten erst mit Hilfe typischer bürokratischer Praktiken und Redensarten als solche von den Polizisten konstruiert werden. Dabei sind die Klienten aber weder passiv polizeilicher Willkür ausgeliefert noch können einflussreiche Klienten die Polizei nach ihrem Gusto manipulieren. In zwei Fallstudien von Verhandlungssituationen wird deutlich, wie Polizisten Autorität in der Interaktion mit Klienten herstellen und legitimieren und welche Maßnahmen Klienten ihrerseits ergreifen, um die Situation zu ihren Gunsten zu gestalten.

Engineering Agent-Oriented Technologies and Programming Languages for Computer Programming and Software Development

Mainstream hardware is becoming parallel, heterogeneous, and distributed on every desk, every home and in every pocket. As a consequence, in the last years software is having an epochal turn toward concurrency, distribution, interaction which is pushed by the evolution of hardware architectures and the growing of network availability. This calls for introducing further abstraction layers on top of those provided by classical mainstream programming paradigms, to tackle more effectively the new complexities that developers have to face in everyday programming. A convergence it is recognizable in the mainstream toward the adoption of the actor paradigm as a mean to unite object-oriented programming and concurrency. Nevertheless, we argue that the actor paradigm can only be considered a good starting point to provide a more comprehensive response to such a fundamental and radical change in software development. Accordingly, the main objective of this thesis is to propose Agent-Oriented Programming (AOP) as a high-level general purpose programming paradigm, natural evolution of actors and objects, introducing a further level of human-inspired concepts for programming software systems, meant to simplify the design and programming of concurrent, distributed, reactive/interactive programs. To this end, in the dissertation first we construct the required background by studying the state-of-the-art of both actor-oriented and agent-oriented programming, and then we focus on the engineering of integrated programming technologies for developing agent-based systems in their classical application domains: artificial intelligence and distributed artificial intelligence. Then, we shift the perspective moving from the development of intelligent software systems, toward general purpose software development. Using the expertise maturated during the phase of background construction, we introduce a general-purpose programming language named simpAL, which founds its roots on general principles and practices of software development, and at the same time provides an agent-oriented level of abstraction for the engineering of general purpose software systems.

Multidimensional item response theory models with general and specific latent traits for ordinal data

The aim of the thesis is to propose a Bayesian estimation through Markov chain Monte Carlo of multidimensional item response theory models for graded responses with complex structures and correlated traits. In particular, this work focuses on the multiunidimensional and the additive underlying latent structures, considering that the first one is widely used and represents a classical approach in multidimensional item response analysis, while the second one is able to reflect the complexity of real interactions between items and respondents. A simulation study is conducted to evaluate the parameter recovery for the proposed models under different conditions (sample size, test and subtest length, number of response categories, and correlation structure). The results show that the parameter recovery is particularly sensitive to the sample size, due to the model complexity and the high number of parameters to be estimated. For a sufficiently large sample size the parameters of the multiunidimensional and additive graded response models are well reproduced. The results are also affected by the trade-off between the number of items constituting the test and the number of item categories. An application of the proposed models on response data collected to investigate Romagna and San Marino residents' perceptions and attitudes towards the tourism industry is also presented.

Engineering in Transition. Approaches, strategies and technologies for implementing system innovation towards sustainability

With the aim to provide people with sustainable options, engineers are ethically required to hold the safety, health and welfare of the public paramount and to satisfy society's need for sustainable development. The global crisis and related sustainability challenges are calling for a fundamental change in culture, structures and practices. Sustainability Transitions (ST) have been recognized as promising frameworks for radical system innovation towards sustainability. In order to enhance the effectiveness of transformative processes, both the adoption of a transdisciplinary approach and the experimentation of practices are crucial. The evolution of approaches towards ST provides a series of inspiring cases which allow to identify advances in making sustainability transitions happen. In this framework, the thesis has emphasized the role of Transition Engineering (TE). TE adopts a transdisciplinary approach for engineering to face the sustainability challenges and address the risks of un-sustainability. With this purpose, a definition of Transition Technologies is provided as a valid instruments to contribute to ST. In the empirical section, several transition initiatives have been analysed especially at the urban level. As a consequence, the model of living-lab of sustainability has crucially emerged. Living-labs are environments in which innovative technologies and services are co-created with users active participation. In this framework, university can play a key role as learning organization. The core of the thesis has concerned the experimental application of transition approach within the School of Engineering and Architecture of University of Bologna at Terracini Campus. The final vision is to realize a living-lab of sustainability. Particularly, a Transition Team has been established and several transition experiments have been conducted. The final result is not only the improvement of sustainability and resilience of the Terracini Campus, but the demonstration that university can generate solutions and strategies that tackle the complex, dynamic factors fuelling the global crisis.

Managing a World Heritage Site: Potentials and limitations of transdisciplinary approaches

Balancing the frequently conflicting priorities of conservation and economic development poses a challenge to management of the Swiss Alps Jungfrau- Aletsch World Heritage Site (WHS). This is a complex societal problem that calls for a knowledge-based solution. This in turn requires a transdisciplinary research framework in which problems are defined and solved cooperatively by actors from the scientific community and the life-world. In this article we re-examine studies carried out in the region of the Swiss Alps Jungfrau-Aletsch WHS, covering three key issues prevalent in transdisciplinary settings: integration of stakeholders into participatory processes; perceptions and positions; and negotiability and implementation. In the case of the Swiss Alps Jungfrau-Aletsch WHS the transdisciplinary setting created a situation of mutual learning among stakeholders from different levels and backgrounds. However, the studies showed that the benefits of such processes of mutual learning are continuously at risk of being diminished by the power play inherent in participatory approaches.

Placing Identity: Town, Land, and Authenticity in Nunavut, Canada

Recent demographic changes have made settlement patterns in the Canadian Arctic increasingly urban. Iqaluit, capital of Canada’s newest territory, Nunavut, is home to the largest concentration of Inuit and non-Inuit populations in the Canadian North. Despite these trends, Inuit cultural identity continues to rest heavily on the perception that to learn how to be authentically Inuit (or to be a better person), a person needs to spend time out on the land (and sea) hunting, fishing, trapping, and camping. Many Inuit also maintain a rather negative view of urban spaces in the Arctic, identifying them as places where Inuit values and practices have been eclipsed by Qallunaat (‘‘white people’’) ones. Some Inuit have even gone so far as to claim that a person is no longer able to be Inuit while living in towns like Iqaluit. This article examines those aspects of Canadian Inuit identity, culture, and tradition that disfavor the acceptance of an urban cultural identity. Based on ethnographic research conducted on Baffin Island in the mid 1990s and early 2000s, the many ways Iqaluit and outpost camp Inuit express the differences and similarities between living on the land and living in town are described. Then follows an examination of how the contrast of land and town is used in the rhetoric of Inuit politicians and leaders. Finally, a series of counterexamples are presented that favor the creation of an authentic urban Inuit identity in the Arctic, including recent attempts on the part of the Nunavut Territorial Government to make education and wage employment in the region more reliant on Inuit Qaujimajatuqangit, or Inuit traditional knowledge.1

The interorganizational challenge of agricultural reform in Bosnia and Herzegovina

The case study reported below examines USAID's "Linking Agricultural Markets with Producers" program. This program complemented Bosnia and Herzegovina's overall sustainable agriculture policies. Implementing organizations quickly recognized that sustainability must be achieved not only from an environmental perspective, but in the interorganizational domain as well. Public, private and nonprofit players had to develop the social, economic and political infrastructure required for sustainable agricultural projects to succeed. These institutional changes were at times more difficult than the sustainable agriculture policies and practices they supported. Framed within LAMP's identification of constraints and proposed solutions for agricultural reform, we explored the interorganizational linkages required for success. We identified three distinct types: 1) those within the international community, 2) those within the local community and 3) those between international and local organizations. The case illustrates the institutional and managerial obstacles to and opportunities for implementing sustainable development reforms in transition settings.

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.

The Alliance for Progress and Housing Policy in Rio de Janeiro and Buenos Aires in the 1960s

This article explores the construction of publicly financed low-income housing complexes in Rio de Janeiro, Brazil, and Buenos Aires, Argentina, in the 1960s. These housing developments were possible thanks to the arrival of foreign economic and technical assistance from the Alliance for Progress. Urban scholars, politicians, diplomats and urbanists of the Americas sought to promote middle-class habits, mass consumption and moderate political behaviour, especially among the poor, by expanding access to homeownership and ‘decent’ living conditions for a burgeoning urban population. As a result, the history of low-income housing should be understood within broader transnational discourses and practices about the ‘modernization’ and ‘development’ of the urban poor.

Can Andean medicine coexist with biomedical healthcare? A comparison of two rural communities in Peru and Bolivia

Background It is commonly assumed that indigenous medical systems remain strong in developing countries because biomedicine is physically inaccessible or financially not affordable. This paper compares the health-seeking behavior of households from rural Andean communities at a Peruvian and a Bolivian study site. The main research question was whether the increased presence of biomedicine led to a displacement of Andean indigenous medical practices or to coexistence of the two healing traditions. Methodology Open-ended interviews and free listing exercises were conducted between June 2006 and December 2008 with 18 households at each study site. Qualitative identification of households’ therapeutic strategies and use of remedies was carried out by means of content analysis of interview transcriptions and inductive interference. Furthermore, a quantitative assessment of the incidence of culture-bound illnesses in local ethnobiological inventories was performed. Results Our findings indicate that the health-seeking behavior of the Andean households in this study is independent of the degree of availability of biomedical facilities in terms of quality of services provided, physical accessibility, and financial affordability, except for specific practices such as childbirth. Preference for natural remedies over pharmaceuticals coexists with biomedical healthcare that is both accessible and affordable. Furthermore, our results show that greater access to biomedicine does not lead to less prevalence of Andean indigenous medical knowledge, as represented by the levels of knowledge about culture-bound illnesses. Conclusions The take-home lesson for health policy-makers from this study is that the main obstacle to use of biomedicine in resource-poor rural areas might not be infrastructural or economic alone. Rather, it may lie in lack of sufficient recognition by biomedical practitioners of the value and importance of indigenous medical systems. We propose that the implementation of health care in indigenous communities be designed as a process of joint development of complementary knowledge and practices from indigenous and biomedical health traditions.

Building the New Society in the Shell of the Old: Finnish-Canadian Hall Socialism and the Canadian Industrial Unionist Support League

The literature on Finnish immigrant working-class movements in North America frequently makes reference to the phenomenon of "hall socialism," so-called because of the central position that the socialist or labor hall occupied in the political, associational, and cultural life of many Finnish communities throughout the twentieth-century. In the 1930s, over 80 such Finnish halls were spread across Canada, and many people associated with these halls vigorously supported the mission of organized labor. This paper will examine the history, ideas, and practices of the Industrial Workers of the World-influenced Canadan Teollisuusunionistien Kannatus Liitto (CTKL; Canadian Industrial Unionist Support League), and its connections to Finnish Canadian hall socialism. The paper will consider the role of the CTKL in supporting workers' struggles, the significance of the hall as a part of the infrastructural bedrock that sustained this support, and the broader interaction between social and radical organizing commitments.

Preparing writing centers and tutors for literacy mediation for working class campus-staff

Writing centers work with writers; traditionally services have been focused on undergraduates taking composition classes. More recently, centers have started to attract a wider client base including: students taking labs that require writing; graduate students; and ESL students learning the conventions of U.S. communication. There are very few centers, however, which identify themselves as open to working with all members of the campus-community. Michigan Technological University has one such center. In the Michigan Tech writing center, doors are open to “all students, faculty and staff.” While graduate students, post docs, and professors preparing articles for publication have used the center, for the first time in the collective memory of the center UAW staff members requested center appointments in the summer of 2008. These working class employees were in the process of filling out a work related document, the UAW Position Audit, an approximately seven-page form. This form was their one avenue for requesting a review of the job they were doing; the review was the first step in requesting a raise in job level and pay. This study grew out of the realization that implicit literacy expectations between working class United Auto Workers (UAW) staff and professional class staff were complicating the filling out and filing of the position audit form. Professional class supervisors had designed the form as a measure of fairness, in that each UAW employee on campus was responding to the same set of questions about their work. However, the implicit literacy expectations of supervisors were different from those of many of the employees who were to fill out the form. As a result, questions that were meant to be straightforward to answer were in the eyes of the employees filling out the form, complex. Before coming to the writing center UAW staff had spent months writing out responses to the form; they expressed concerns that their responses still would not meet audience expectations. These writers recognized that they did not yet know exactly what the audience was expecting. The results of this study include a framework for planning writing center sessions that facilitate the acquisition of literacy practices which are new to the user. One important realization from this dissertation is that the social nature of literacy must be kept in the forefront when both planning sessions and when educating tutors to lead these sessions. Literacy scholars such as James Paul Gee, Brian Street, and Shirley Brice Heath are used to show that a person can only know those literacy practices that they have previously acquired. In order to acquire new literacy practices, a person must have social opportunities for hands-on practice and mentoring from someone with experience. The writing center can adapt theory and practices from this dissertation that will facilitate sessions for a range of writers wishing to learn “new” literacy practices. This study also calls for specific changes to writing center tutor education.
