Sammanfattning : Hydrogeological and geophysical methods were applied in the Río Artiguas watershed, a mountain basin located in central Nicaragua. This area is under environmental stress from anthropogenic activities like gold mining using mercury and waste disposal into the streams. LÄS MER
Sammanfattning : The purpose of the thesis is to further understand key conceptual and operational challenges that international aid donors, and public and private institutions, face while designing and implementing alternative forms of social housing finance which aim to be inclusive for the urban poor. Based on an in-depth study of the work of the Foundation for the Promotion of Local Development (PRODEL) in three cities in Nicaragua during a period of 15 years, the thesis tries to answer three research questions: What are the constraints the urban poor face in financing the incremental way they build their individual housing and collective assets? Why does housing microfinance not always enhance inclusion of the urban poor? How does the tension between the goal of achieving financial sustainability and increasing financial inclusion affect the policy of international donors and governments, and the practice of local financial institutions? To answer these questions, the thesis adopts a realist approach as well as a critical case study method as used in disciplines such as political science and history to explain the trends and complexities of the phenomena investigated, and formulates an argument in the form of a proposition: if financial exclusion occurs in PRODEL it might also occur elsewhere.

3. On the nature of self-assembly in low-density condensed matter : A classical molecular dynamics approach
Sammanfattning : The study of the physics of self-assembly in low-density condensed matter is an extremely interesting, mostly unexplored field of scientific research. The contribution reported in this thesis explains how this problem can be addressed using molecular dynamics simulation of 3D systems composed by simple, identical particles, interacting via a spherically symmetric pair potential, which belongs to the class of Dzugutov potentials.

Sammanfattning : This thesis consists of three distinct articles that can be read separately. Each one has been awarded a chapter of its own. The independence of these chapters should not be taken as meaning that they are unrelated. Besides belonging all to the subfield of macroeconomics, they share the common feature of being inherently economic policy oriented. LÄS MER
