This chapter explores the responsibility of armed non-state actors for reparations to victims. Traditionally international law has focused on the responsibility of the state, and more recently the responsibility of convicted individuals before the International Criminal Court, to provide reparations for international crimes. Yet despite the prevalence of internal armed conflict over the past few decades, there responsibility of armed groups for reparations has been neglected in international law. Although there is a tentative emerging basis for armed groups to provide reparations under international law, such developments have not yet crystallized into hard law. However, when considering the more substantive practice of states in Northern Ireland, Colombia and Uganda, a greater effort can be discerned in ensuring that such organizations are responsible for reparations. This paper finds that not only can armed non-state actors be held collectively responsible for reparations, but due to the growing number of internal armed conflict they can play an important role in ensuring the effectiveness of reparations in remedying victims’ harm. Yet, finding armed groups responsible for reparations is no panacea for accountability, due to the nature of armed conflicts, responsibility may not be distinct, but overlapping and joint, and such groups may face difficulties in meeting their obligations, thus requiring a holistic approach and subsidiary role for the state.

Civic participation is important for peacebuilding and democratic development; however, the role of mental health has been largely overlooked by policymakers aiming to stimulate engagement in civil society. This study investigated antecedents of civic participation in Colombia, a setting of protracted political conflict, using bootstrapped mediation in path analysis. Past exposure to violence, experience with community antisocial behavior, and perceived social trust were all significantly related to civic participation. In addition, depression mediated the impact of past exposure to political violence and perceived social trust, but not community antisocial behavior, on civic participation. In this context, findings challenged depictions of helpless victims and instead suggested that when facing greater risk (past violence exposure and community antisocial behavior), individuals responded in constructive ways, taking on agency in their communities. Social trust in one’s neighbors and community also facilitated deeper engagement in civic life. Relevant to the mediation test, interventions aiming to increase civic participation should take mental health into account. Limitations and possible future research are discussed.

Given the increase of reconciliation processes initiated amid on-going violence, this study focuses on community reconciliation and its relation to structural transformation, or social reconstruction through reforming unjust institutions and practices that facilitate protracted violent conflict. Drawing lessons from the Caribbean coast of Colombia, mixed method analyses include eight in-depth interviews and 184 surveys. Four key dimensions of reconciliation truth, justice, mercy, peace are examined. In the interviews, participants prioritize reconstructing the truth and bringing perpetrators to justice as essential aspects of reconciliation. Notions of mercy and forgiveness are less apparent. For the participants, sustainable peace is dependent on structural transformation to improve livelihoods. These data, however, do not indicate how this understanding of reconciliation may relate to individual participation in reconciliation processes. Complementing the qualitative data, quantitative analyses identify some broad patterns that relate to participation in reconciliation events. Compared to those who did not participate, individuals who engaged in reconciliation initiatives report higher levels of personal experience with violence, live alongside demobilized paramilitaries, are more engaged in civic life, and express greater preference for structural transformation. The paper concludes with policy implications that integrate reconciliation and structural transformation to deepen efforts to rebuild the social fabric amid violence.

El presente trabajo quiere presentar un panorama de los grupos étnicos indígenas que hoy pueblan el territorio colombiano. La "visión etnológica sobre los grupos étnicos indígenas actuales de Colombia con su bibliografía" tiene como objeto presentar la riqueza étnica de las minorías indígenas que, junto con los negros y blancos, conforman el pueblo colombiano. Como lo indica el título, esta no es una investigación profunda sobre cada grupo, pero es una recopilación de datos, informes y libros ya existentes para dar una visión de cada grupo étnico mencionado, aunque sobre algunos los datos son escasos, por varias razones que especialmente debido a la poca literatura eústente en la etnología actual. Después del índice, la introducción y agradecimientos, se encuentra la bibliografia general, a la cual sigue la presentación de los deparamentos, intendencias y comisarías donde existen los resguardos y las reservas indígenas, complementados al final del trabajo con su respectivo mapa; en cada resguardo o reserva aparece entre paréntesis el número bajo el cual se puede buscar en el mapa. A continuación se éncuentta la clasificación de los grupos étnicos por familias lingüísticas y la descripción de cada uno, ordenados alfabéticamente, divididos en subtítulos como nominación, o bajo cuales nombres se conoce el grupo, localización, resguardos y/o reservas indígenas, lengua y/o familia linguística a Ia cual pertenece, vivienda, economía, vestidos y adornos, organización socio-política, creencias y rituales, aculturación. Aunque los subtítulos no se compaften siempre, debido a la escasez de trabajos sobre algunos grupos y/o a su falta de disponibilidad, espero que aún de este modo el presente trabajo será de utilidad y por ello despuás de cada gupo se menciona la bibliografía de los trabajos existentes sobre el mismo, para quienes quieran profundizar sus conocimientos sobre el tema.

Neste trabalho foram estudadas as interacções entre Mycobacterium bovis e células hospedeiras, na perspectiva de aplicar os conhecimentos resultantes desse estudo ao melhoramento do diagnóstico da tuberculose bovina. Foi estudada a dinâmica da infecção de células fagocíticas com estirpes de M. bovis, com ênfase para a invasão e multiplicação intracelular das micobactérias. Avaliações efectuadas por citometria de fluxo, microscopia de fluorescência e contagem de colónias demonstraram que as micobactérias invadiram e replicaram em todos os modelos celulares, sendo que as células epiteliais de pulmão de bovino foram as mais permissivas ao seu crescimento. Foi nas células macrofágicas J774 e THP-1 que se verificaram as maiores concentrações micobacterianas, pelo que foram utilizadas para a detecção e identificação de M. bovis por um método molecular. A optimização da extracção de DNA, por um processo mecânico, e o desenvolvimento do método de PCR-RFLP baseado no gene gyrB, com controlo interno, permitiram a identificação de M. bovis. A sensibilidade deste método foi de 100% quando aplicado a estirpes isoladas e apenas de 40% quando utilizado directamente em amostras de macerados de tecidos de bovinos com tuberculose. Uma pré-incubação (3 dias) das amostras nas culturas celulares contribuiu para melhorar significativamente a sensibilidade (77%) do PCR-RFLP gyrB. A cultura celular, como matriz a ser utilizada para aumentar a quantidade de M. bovis presente em amostras biológicas, revela-se um método promissor para o diagnóstico laboratorial rápido, específico e sensível da tuberculose bovina. ### - Summary - Interactions between Mycobacterium bovis and host cells were studied with the purpose to apply the outcome knowledge in the improvement of bovine tuberculosis diagnosis. The dynamic of infection of four cell models with three strains of M. bovis was evaluated, with emphasis given to the invasion and intracellular multiplication of mycobacteria. Assessments by flow cytometry, fluorescence microscopy and colony counting showed that every cell models permitted the replication of mycobacteria, although bovine lung epithelial cells had been the most permissive one. The highest mycobacteria) load was found, however, in J774 and THP-1 macrophages, and hence these cells were used for the optimization of a molecular method for detection and identification of M. bovis. The optimisation of a DNA extraction step, by a mechanical process, and the development of PCR-RFLP based on gyrB gene, with an internal control, allowed the identification of M. bovis. The sensitivity of this method was 100% when applied to isolated strains and only 40% when directly used on samples of macerated of tissues from cattle with tuberculosis. Assays in which a pre-incubation step (three days) of biological samples in cell cultures was introduced significantly improved the sensitivity (77%) of the gyrB PCR-RFLP. Cell cultures as a support for growth and rapid isolation of M. bovis is a promising method for the specific, sensitive and rapid laboratorial diagnosis of bovine tuberculosis.

The potential of online learning has long afforded the hope of providing quality education to anyone, anywhere in the world. The recent development of Massive Open Online Courses (MOOCs) heralded an exciting new breakthrough by providing free academic instruction and professional skills development from the world’s leading universities to anyone with the sufficient resources to access the internet. The research in Advancing MOOCs for Development Initiative study was designed to analyze the MOOC landscape in developing countries and to better understand the motivations of MOOC users and afford insights on the advantages and limitations of MOOCs for workforce development outcomes. The key findings of this study challenge commonly held beliefs about MOOC usage in developing countries, defying typical characterizations of how people in resource constrained settings use technology for learning and employment. In fact, some of the findings are so contrary to what has been reported in the U.S. and other developed environments that they raise new questions for further investigation.

Colombia’s Internet connectivity has increased immensely. Colombia has also ‘opened for business’, leading to an influx of extractive projects to which social movements object heavily. Studies on the role of digital media in political mobilisation in developing countries are still scarce. Using surveys, interviews, and reviews of literature, policy papers, website and social media content, this study examines the role of digital and social media in social movement organisations and asks how increased digital connectivity can help spread knowledge and mobilise mining protests. Results show that the use of new media in Colombia is hindered by socioeconomic constraints, fear of oppression, the constraints of keyboard activism and strong hierarchical power structures within social movements. Hence, effects on political mobilisation are still limited. Social media do not spontaneously produce non-hierarchical knowledge structures. Attention to both internal and external knowledge sharing is therefore conditional to optimising digital and social media use.
