T1 - Complex rupture mechanism and topography control symmetry of mass-wasting pattern, 2010 Haiti earthquake JF - GEOMORPHOLOGY N2 - The 12 January 2010 M-w 7.0 Haiti earthquake occurred in a complex deformation zone at the boundary between the North American and Caribbean plates. Combined geodetic, geological and seismological data posited that surface deformation was driven by rupture on the Leogane blind thrust fault, while part of the rupture occurred as deep lateral slip on the Enriquillo-Plantain Garden Fault (EPGF). The earthquake triggered >4490 landslides, mainly shallow, disrupted rock falls, debris-soil falls and slides, and a few lateral spreads, over an area of similar to 2150 km(2). The regional distribution of these slope failures defies those of most similar earthquake-triggered landslide episodes reported previously. Most of the coseismic landslides did not proliferate in the hanging wall of the main rupture, but clustered instead at the junction of the blind Leogane and EPGF ruptures, where topographic relief and hillslope steepness are above average. Also, low-relief areas subjected to high coseismic uplift were prone to lesser hanging wall slope instability than previous studies would suggest. We argue that a combined effect of complex rupture dynamics and topography primarily control this previously rarely documented landslide pattern. Compared to recent thrust fault-earthquakes of similar magnitudes elsewhere, we conclude that lower static stress drop, mean fault displacement, and blind ruptures of the 2010 Haiti earthquake resulted in fewer, smaller, and more symmetrically distributed landslides than previous studies would suggest. Our findings caution against overly relying on across-the-board models of slope stability response to seismic ground shaking. (C) 2012 Elsevier B.V. All rights reserved.

Im Laufe dieser Phasen, die keineswegs einer chronologischen Ordnung folgen, sondern zum Teil parallel verlaufen, nimmt Humboldt verschiedene soziale Rollen an, die ihren Ausdruck in spezifischen Haltungen und Handlungen finden. In ihrer Summe zeichnen sie ein für das Verständnis von Humboldts Persönlichkeit typisches Psychogramm: ein selbstbewusster Moralist, ein rigoroser, beinahe kriminalistisch agierender Wissenschaftler, ein politisch zurückhaltender Akteur. N2 - This text seeks to reframe the widely known and well-researched topic of “Humboldt and Slavery” biographically and subscribes to a simple premise: In the decades following his voyage through the American tropics (1799 –1804), Humboldt goes through various stages in addressing the topic of slavery. In the course of these stages, which by no means follow a chronological order but run partly parallel, Humboldt assumes different social roles that fi nd expression in specifi c attitudes and actions. Taken together, they draw a psychogram typical for understanding Humboldt’s personality: a self-confi dent moralist, a rigorous scientist, a politically reserved activist. N2 - El objetivo de este texto es reclasificar desde un punto de vista biográfico el ampliamente conocido e investigado tema de „Humboldt y la esclavitud“ y se guía por la siguiente tesis: Humboldt pasa por varias fases en su interés por el tema de la esclavitud en las décadas posteriores a su viaje por los trópicos americanos (1799 –1804). En el transcurso de estas fases, que no siguen en absoluto un orden cronológico sino que transcurren en parte paralelamente, Humboldt asume diferentes roles sociales que se expresan en actitudes y acciones específicas. En conjunto, presentan un psicograma típico para comprender la personalidad de Humboldt: un moralista confiado, un científico riguroso, un actor políticamente reservado.

Asking what makes the implementation of peacekeeping interventions complex and how complexity is resolved, I find that formal, contractual mechanisms only rarely effectively reduce complexity – and that micro relations fill this gap. Micro relations are personal relationships resulting from frequent face-to-face interaction in professional and – equally importantly – social contexts. This study offers an explanation as to why micro relations are important for coping with complexity, in the form of a causal mechanism. For this purpose, I bring together theoretical and empirical knowledge: I draw upon the current debate on ‘institutional complexity’ (Greenwood et al. 2011) in organizational institutionalism as well as original empirical evidence from a within-case study of the peacekeeping intervention in Haiti, gained in ten weeks of field research. In this study, scholarship on institutional complexity serves to identify theoretical causal channels which guide empirical analysis. An additional, secondary aim is pursued with this mechanism-centered approach: testing the utility of Beach and Pedersen’s (2013) theory-testing process tracing. Regarding the first research question – what makes the implementation of peacekeeping interventions complex –, the central finding is that complexity manifests itself in the dual role of organizations as cooperation partners and competitors for (scarce) resources, turf and influence. UN organizations, donor agencies and international NGOs implementing peacekeeping activities in post-conflict environments have chronic difficulty mastering both roles because they entail contradictory demands: effective cooperation requires information exchange, resource and responsibility-sharing as well as external scrutiny, whereas prevailing over competitors demands that organizations conceal information, guard resources, increase relative turf and influence, as well as shield themselves from scrutiny. Competition fuels organizational distrust and friction – and impedes cooperation. How is this complexity resolved? The answer to this second research question is that deep-seated organizational competition is routinely mediated – and cooperation motivated – in micro relations and micro interaction. Regular, frequent face-to-face interaction between individual organizational members generates social resources that help to transcend organizational distrust and conflict, most importantly familiarity with each other, personal trust and belief in reciprocity. Furthermore, informal conflict mediation and control mechanisms – namely, open discussion, mutual monitoring in direct interaction and social exclusion – enhance solidarity and mutual support.
