Abstract: We explore inflation dynamics in the period following the Great Recession for ten different countries for which we have data on the natural rate of unemployment and agents’ inflation expectations. We find that, out of the ten countries analyzed, there is evidence of missing disinflation for seven of them, and, furthermore, the traditional Phillips curve predicts several quarters with negative average inflation (deflation) for six of those that experienced missing disinflation episodes. While analyzing possible explanations within the framework of an expectations-augmented Phillips curve, we find that controlling for the unemployment gap, accounting for a possible flattening of the Phillips curve across time, and considering either households’ or professionals’ inflation forecasts as proxies for firms’ inflation expectations can account for the absence of strong disinflationary pressures since 2009. Resumen: Exploramos las dinámicas inflacionarias de diez países para los que tenemos datos sobre la tasa natural de desempleo y expectativas de inflación de los agentes económicos, en el período posterior a la Gran Recesión. Encontramos que, de los diez países analizados, hay evidencia de una ausencia de desinflación en siete de ellos y, además, la curva de Phillips tradicional predice varios trimestres con inflación promedio negativa (deflación) para seis de los que experimentaron episodios de desinflación ausente. Al analizar las posibles explicaciones en el marco de una curva de Phillips con expectativas aumentadas, encontramos que controlar por la brecha de desempleo, tomar en cuenta un posible aplanamiento de la curva de Phillips a lo largo del tiempo, y considerar los pronósticos de inflación de los hogares o los profesionales como sustitutos de las expectativas de inflación de las empresas pueden explicar la ausencia de fuertes presiones desinflacionarias desde 2009.

Abstract: Currently, the Colombian government and the Revolutionary Armed Forces of Colombia (FARC, acronym in Spanish) are in peace negotiations. After more than 50 years of armed conflict, an ongoing process of reintegration of past demobilizations, and innumerable victims of conflict, peacebuilding becomes a key aspect for societal transformation and reconciliation. Although the transition from conflict to peace is difficult, education can play an important role to achieve this goal. The literature review suggests that there are links between education and peacebuilding. First, this relationship depends on society transformations that can result from inclusive education systems. Second, support education in peacebuilding could have positive effects for security, governance, and the economic and social sectors. Third, education can develop skills, shape non-violent behaviors, and tackle inequality issues. Fourth, peace education can offer a range of initiatives that contribute to peacebuilding. And fifth, there are challenges for education in peacebuilding, which are related to the different interpretation and approach from stakeholders and a lack of allocation of resources in social sectors. Due to the benefits of education and its importance after conflict, the Research Consortium on Education and Peacebuilding created the Theoretical Framework for Analyzing the Contribution of Education to Sustainable Peacebuilding: 4Rs in Conflict-Affected Contexts. The main argument of the 4Rs framework is that in order to achieve sustainable peacebuilding, education should address redistribution, recognition, representation and reconciliation. Under this premise, this study analyzes how education policies in Colombia from 2010 to 2014 tackle issues that contribute to sustainable peace.

Abstract: This research aimed to provide insight into the contribution of alternative online media in peacebuilding. Two alternative online media were chosen since they started creating narratives from the victim’s perspective, giving voice to communities typically neglected by society and mainstream media. Additionally, this research proposed an intersection between the concepts of participatory journalism and citizen media, from the reviewed theory. A qualitative study was developed to answer three research questions: How are social issues regarding peasants, indigenous people, and students represented in Colombian alternative online media Pacifista and Rutas del Conflicto in post-conflict times?, what are the motivations of Colombian alternative online media and their journalists when portraying marginalized in the media platforms?, and what are the challenges that alternative media in Colombia face when carrying out investigative journalism about these communities in post-conflict times? Data was collected using in-depth critical discourse analysis and semi structured interviews. For analysis, data collected from both methods was compared in order to strengthen the validity of the findings which were also enrolled in academic discussion with the theory and studies conducted in the field. The study found that alternative online media have helped in peacebuilding when portraying narratives about the communities and giving them visibility. The use of their journalistic work by experts on reparation and peace is also an evidence of their contribution. The enrollment of communities in editorial processes allowed the communities themselves to transform their self-image and identity. The intersection of theories proposed in this study grants sense to the evolution of citizen media in terms of appropriation of digital media. The limitations and implications of this study highlight the need for further research on the field.

Abstract: In this dissertation I examine the ways in which the community of Coquí, Colombia negotiate their identity. I argue that local forms of representation are re-created in forms of daily life activities such as farming, fishing and cooking. At the same time, those negotiations are connected to structures such as the black and indigenous territorial autonomy, the National Development Plan of Colombia (PND), and the presence of structural violence and narco-traffic. I focus on the use of local discourses as a mechanism to explain the territorial tensions with modernity, race, food, political agency and autonomy. I conclude by suggesting that the local territorial autonomy has permitted the consolidation of local food activism, unique ontological relations with nature, perspectives of black political activism, race and, sustainable economies that dialogue in particular ways with the current global capitalist model.

Abstract: Form-Based Code (FBC) is an urban design tool that contributes to building a highquality public realm for cities and particularly, neighbourhood communities. Its principles including mix-uses, physical form over separation of uses, encouraging walkability, and cycling as well as community engagement through charrettes (1). Therefore, it is recognised as an alternative planning tool that can offer an illustrated compilation of regulations and required design elements for specific development to achieve a long-term vision of the cities. Since 2000, in Bogota, Colombia, most of the neighbourhood’s units have been developed by gated neighbourhoods that show lack of relation with the public realm, promoting insecurity and spatial segregation. Indeed, in most cases, the Colombian planning system does not control the development gated enclaves (Blandy & Parsons, 2003) being the housing type preferred by almost 2.7 million of citizens. Even though some regulations have been adopted in the land management plan (POT), partial plans (PP) and other planning tools, they are still wide and scarce to mitigate the unsustainable growth of gated enclaves. Through a comparative analysis, this dissertation address at studying to what extend the existing local regulations and guidelines for developing gated communities agree with the FBC’s principles. The research concluded with some recommendations and actions for applying the FBC in gated communities in Bogota that could be applied in other towns with similar urban conditions.

Resumen: Form-Based Code (FBC) es una herramienta de diseño urbano que contribuye a construir un ámbito público de alta calidad para las ciudades y, en particular, las comunidades barriales. Sus principios incluyen: usos mixtos, la forma física sobre la separación de usos, fomento de la transitabilidad y el ciclismo, así como la participación de la comunidad a través de charrettes (1). Por tanto, se reconoce como una herramienta de planificación alternativa que puede ofrecer una recopilación ilustrada de normativas y elementos de diseño requeridos para el desarrollo específico de una visión a largo plazo de las ciudades. Desde el año 2000, en Bogotá, Colombia, la mayoría de las unidades del barrio han sido desarrolladas a través de conjuntos cerrados que muestran falta de relación con el ámbito público, promoción de inseguridad y segregación espacial. De hecho, en la mayoría de los casos, el sistema de planificación colombiano no controla el desarrollo de enclaves cerrados (Blandy & Parsons, 2003), siendo este, el tipo de vivienda preferido por casi 2,7 millones de ciudadanos. Aunque se han adoptado algunas regulaciones en el plan de ordenamiento territorial (POT), planes parciales (PP) y otras herramientas de planificación, aún son amplias y escasas para mitigar el crecimiento insostenible de los enclaves cerrados. A través de un análisis comparativo, esta disertación aborda el estudio de hasta qué punto las regulaciones y pautas locales existentes para el desarrollo de comunidades cerradas están de acuerdo con los principios de las Formas Basadas en Códigos (FBC). La investigación concluye con algunas recomendaciones y acciones para la aplicación de los FBC, sobre los conjuntos cerrados de Bogotá, que bien podrían también aplicarse en otros lugares con similares condiciones urbanas.

Abstract: The development of new technologies in genetic research and the increasing understanding of the human genome has led, in the last decades, to an increase in the use of human tissue in the fields of research, diagnosis and medical treatment. Several legal models have been proposed for the protection of the rights of the original source of the tissue and for the circulation and use of this material for research. The main aim of this thesis is to explore the so-called contractual model. According to this model, the conclusion of contracts on human tissue could protect better than any other mechanism the rights and interests of the parties involved in the circulation of tissue for research. For this purpose, the objective of this thesis is to answer the following research question: what are the limits to the validity of contracts on human tissue in the Italian, English and EU legal system? In order to establish such limits, this study focuses on the following possible cases of contractual relations for the transfer and use of human tissue: a) Gratuitous contracts between the first transferor and the first recipient of human tissue; b) Non-gratuitous contracts between the first transferor and the first recipient; c) Contracts between the first and subsequent recipients. The research was carried out using two different legal methods. Firstly, the doctrinal research method was used to investigate the scope and content of the multi-level sources of law (national, supranational and international) that constitute the legal framework for the determination of the limits to the validity of contracts on human tissue. Secondly, the functional approach was used for the comparative analysis of the national legal systems of Italy and England. The research concludes that it is desirable to regulate, via contract law legislative provisions, the tissue transfers for the purposes of research. This regulation should place on the first recipient a clear set of information duties towards the first transferor of the tissue. In addition, such regulation should include mandatory and default rules for contracts between the first transferor and first recipient. The interaction between mandatory norms and default rules could achieve a strengthened protection of the autonomy of the first transferor of tissue. This research also demonstrates that the conclusion of sales and other non-gratuitous contracts on human tissue between first transferor and the first recipient should not be prohibited.

Abstract: Antimicrobial peptides (AMPs) are small chains of amino acids with the ability to cause bacterial death. AMPs are usually amphiphilic but diverse in charge and structure. The mechanism or mechanisms that AMPs implement to kill bacteria are still under discussion. Studies in model membranes have widely demonstrated the capacity of AMPs to interact with and disrupt the bacterial cell membrane. There are however, good reasons to suspect that AMP interactions with nonmembrane components of bacteria are important. For instance, there is an enormous discrepancy between the peptide to lipid molar ratio (P:L) necessary to generate membrane disruption in model systems (1:100), and the P:L necessary to stop bacterial growth, i.e. the minimal inhibitory concentration (MIC) (10-100:1). One potential explanation for this discrepancy is that AMPs may interact with non-membrane components of the bacterial cell envelope. The peptidoglycan (PGN) layer is one of the primary non-membrane components of Gram-positive bacterial cell envelopes and is responsible for cell shape and stability. Currently, there is an open discussion about whether PGN can entrap AMPs and prevent them from reaching the cell membrane or, instead promote the accumulation of AMPs on the cell membrane. The primary experimental approach employed in this thesis was 2H NMR spectroscopy of intact bacteria with 2H-labeled membranes. Specifically, since the quadrupolar splittings obtained from the spectra are proportional to the order parameter of the lipid acyl chains, the spectra reflect the structure and dynamics of the membrane. In particular, 2H NMR spectroscopy allows us to characterize the disruption of lipid bilayers caused by AMPs. In this study, different methods to grow 2H-membrane-enriched bacteria were optimized to obtain 2H NMR spectra of E. coli LA8, E. coli JM109 and B. subtilis. Additionally, 2H NMR was used to observe the level of disruption of the cell membrane of B. subtilis caused by the presence of different AMPs, MSI-78 and BP100. Both MSI-78 and BP100 caused the same level of membrane disruption at similar concentrations. Separately, comparison of the 2H NMR spectra of B. subtilis with intact and compromised PGN layers showed no differences. The lack of change in the spectra of PGN-compromised and PGN intact bacteria indicates that there is no change in the dynamics or structure of the lipid bilayer even with a weakened PGN layer. Finally, the disruption caused by MSI-78 and BP100 was measured in B. subtilis with a compromised PGN layer. The results indicate that there is no change in the level of membrane disruption caused by MSI-78 and BP100 when the PGN layer is partially removed.
