TY - JOUR A1 - Iturrizaga, Lasafam A1 - Charrier G., Reynaldo T1 - Sudden glacier advances in the Cachapoal Valley, Southern Central Andes of Chile (34 degrees S) JF - Journal of South American earth sciences N2 - Throughout the Andes Mountains of South America, a general trend of glacier shrinkage has taken place in modern times. However, a few glaciers have undergone considerable temporally advances or even surged during the mid-19th to 20th century CE. These valley glaciers are mainly located in the Central Andes of Chile and Argentina. The research presented here focuses on the changes of the Cachapoal Glacier in the Southern Central Andes of Chile. Spectacular glacier advances occurred at least three times in historical times, which lead to river blockages and successive lake outburst floods. The glacier advances were reconstructed with a multi-method approach including geomorphological mapping, Be-10 cosmogenic exposure dating of moraines, multi-temporal comparison of historical and recent photographs and paintings as well as the interpretation of aerial photographs and satellite images and the analysis of early travel reports. The article highlights the diversity of environmental conditions for the formation of glaciers in terms of the topographical and climatic setting and the resulting distinct glacier behavior along the Andes Mountains. It is argued for the Cachapoal Glacier that the glacier advances are intrinsic to the glacier type and may not be necessarily climate-dependent. This is characteristic for avalanche-fed glaciers of which the glacier dynamic is strongly controlled by the topographic setting and sudden inputs of ice and rock avalanches as well as by the specific debris transfer system and hydrological drainage pattern. At the regional level, the fluctuations of the Cachapoal Glacier are compared with glaciers of neighboring mountain ranges in the Southern Central Andes and at the global scale with those of the Karakoram Mountains in High Asia with a similar dynamic glacier behavior.

T1 - Bayesian detection of streamflow response to earthquakes JF - Water resources research : an AGU journal N2 - Detecting whether and how river discharge responds to strong earthquake shaking can be time-consuming and prone to operator bias when checking hydrographs from hundreds of gauging stations. We use Bayesian piecewise regression models to show that up to a fifth of all gauging stations across Chile had their largest change in daily streamflow trend on the day of the M-w 8.8 Maule earthquake in 2010. These stations cluster distinctly in the near field though the number of detected streamflow changes varies with model complexity and length of time window considered. Credible seismic streamflow changes at several stations were the highest detectable in eight months, with an increased variance of discharge surpassing the variance of discharge following rainstorms. We conclude that Bayesian piecewise regression sheds new and unbiased insights on the duration, trend, and variance of streamflow response to strong earthquakes, and on how this response compares to that following rainstorms.

Digital technologies materialized the court practices in ways unthinkable shortly before the pandemic creating resonances with judicial and legal regulation, as well as frictions. A better understanding of the dynamics at play in the digitalization of courts is paramount for designing justice systems that serve their users better, ensure fair and timely dispute resolutions, and foster access to justice. Building on three major bodies of literature —e-justice, digitalization and organization studies, and design research— Designing for Digital Justice takes a nuanced approach to account for human and more-than-human agencies. Using a qualitative approach, I have studied in depth the digitalization of Chilean courts during the pandemic, specifically between April 2020 and September 2022. Leveraging a comprehensive source of primary and secondary data, I traced back the genealogy of the novel materializations of courts’ practices structured by the possibilities offered by digital technologies. In five (5) cases studies, I show in detail how the courts got to 1) work remotely, 2) host hearings via videoconference, 3) engage with users via social media (i.e., Facebook and Chat Messenger), 4) broadcast a show with judges answering questions from users via Facebook Live, and 5) record, stream, and upload judicial hearings to YouTube to fulfil the publicity requirement of criminal hearings. The digitalization of courts during the pandemic is characterized by a suspended normativity, which makes innovation possible yet presents risks. While digital technologies enabled the judiciary to provide services continuously, they also created the risk of displacing traditional judicial and legal regulation. Contributing to liminal innovation and digitalization research, Designing for Digital Justice theorizes four phases: 1) the pre-digitalization phase resulting in the development of regulation, 2) the hotspot of digitalization resulting in the extension of regulation, 3) the digital innovation redeveloping regulation (moving to a new, preliminary phase), and 4) the permanence of temporal practices displacing regulation. Contributing to design research Designing for Digital Justice provides new possibilities for innovation in the courts, focusing at different levels to better address tensions generated by digitalization. Fellow researchers will find in these pages a sound theoretical advancement at the intersection of digitalization and justice with novel methodological references. Practitioners will benefit from the actionable governance framework Designing for Digital Justice Model, which provides three fields of possibilities for action to design better justice systems. Only by taking into account digital, legal, and social factors can we design better systems that promote access to justice, the rule of law, and, ultimately social peace. N2 - Durch COVID-19 mussten zu Beginn des Jahres 2020 die Gerichte weltweit, um ihren Dienst fortzusetzen, Onlinekommunikation und digitale Technologien nutzen. Die digitalen Technologien haben die Gerichtspraktiken in einer Weise verändert, die kurz vor der Pandemie noch undenkbar war, was zu Resonanzen mit der Rechtsprechung und der gesetzlichen Regelung sowie zu Reibungen führte. Ein besseres Verständnis der Dynamik, die bei der Digitalisierung von Gerichten im Spiel ist, ist von entscheidender Bedeutung für die Gestaltung von Justizsystemen, die ihren Nutzern besser dienen, faire und zeitnahe Streitbeilegung gewährleisten und den Zugang zur Justiz und zur Rechtsstaatlichkeit fördern. Aufbauend auf den drei großen Themenkomplexen E-Justiz, Digitalisierung und Organisationen sowie Designforschung verfolgt „Designing for Digital Justice“ einen nuancierten Ansatz, um menschliche und nicht-menschliche Akteure zu berücksichtigen. Mit Hilfe eines qualitativen Forschungsansatzes habe ich die Digitalisierung der chilenischen Gerichte während der Pandemie, insbesondere im Zeitraum von April 2020 und September 2022, eingehend untersucht. Auf der Grundlage einer umfassenden Quelle von Primär- und Sekundärdaten habe ich die Genealogie der neuartigen Materialisierung von Gerichtspraktiken zurückverfolgt, die durch die Möglichkeiten der digitalen Technologien strukturiert wurden. In fünf (5) Fallstudien zeige ich im Detail, wie die Gerichte 1) aus der Ferne arbeiten, 2) Anhörungen per Videokonferenz abhalten, 3) mit Nutzern über soziale Medien (beispielsweise Facebook und Chat Messenger) in Kontakt treten, 4) eine Sendung mit Richtern, die Fragen von Nutzern beantworten, über Facebook Live ausstrahlen und 5) Gerichtsverhandlungen aufzeichnen, streamen und auf YouTube hochladen, um die Anforderungen an die Öffentlichkeit von Strafverhandlungen zu erfüllen. Hierbei zeigt sich, dass digitale Technologien der Justiz zwar eine kontinuierliche Bereitstellung von Dienstleistungen ermöglichten. Sie bergen aber auch die Gefahr, dass sie die traditionelle gerichtliche und rechtliche Regulierung verdrängen. Als Beitrag zum Forschungsstrom zu „Liminal Innovation“ und Digitalisierung theoretisiert „Designing for Digital Justice“ vier Phasen: 1) Vor-Digitalisierung, die zur Entwicklung von Regulierung führt, 2) der Hotspot der Digitalisierung, der zur Ausweitung der Regulierung führt, 3) digitale Innovation, die die Regulierung neu entwickelt (Übergang zu einer neuen, provisorischen Phase) und 4) die Permanenz der temporären Praktiken, die die Regulierung verdrängt. Als Beitrag zur Designforschung bietet „Designing for Digital Justice“ neue Möglichkeiten für die Gestaltung von Justizsystemen, indem es Spannungen und Interventionsebenen miteinander verbindet. Forscherkolleg*innen finden auf diesen Seiten eine fundierte theoretische Weiterentwicklung an der Schnittstelle von Digitalisierung und Gerechtigkeit sowie neue methodische Hinweise. Praktiker sollen von dem Handlungsrahmen „Designing for Digital Justice Model“ profitieren, der drei Handlungsfelder für die Gestaltung besserer Justizsysteme bietet. Nur wenn wir die digitalen, rechtlichen und sozialen Akteure berücksichtigen, können wir bessere Systeme entwerfen, die sich für den Zugang zur Justiz, die Rechtsstaatlichkeit und letztlich den sozialen Frieden einsetzen. N2 - A principios de 2020, con la COVID-19, los tribunales de justicia de todo el mundo tuvieron que ponerse en línea para continuar con el servicio. Las tecnologías digitales materializaron las prácticas de los tribunales de formas impensables poco antes de la pandemia, creando resonancias con la regulación judicial y legal, así como fricciones. Comprender mejor las dinámicas en juego en la digitalización de los tribunales es primordial para diseñar sistemas de justicia que sirvan mejor a sus usuarios, garanticen una resolución de conflictos justa y oportuna y fomenten el acceso a la justicia. Sobre la base de tres grandes temas en la literatura -justicia electrónica, digitalización y organizaciones, e investigación del diseño-, Designing for Digital Justice adopta un enfoque matizado para tener en cuenta los organismos humanos y más que humanos. Utilizando un enfoque cualitativo, he estudiado en profundidad la digitalización de los tribunales chilenos durante la pandemia, concretamente entre abril de 2020 y septiembre de 2022. Aprovechando una amplia fuente de datos primarios y secundarios, he rastreado la genealogía de las nuevas materializaciones de las prácticas de los tribunales estructuradas por las posibilidades que ofrecen las tecnologías digitales. En cinco (5) estudios de caso, muestro en detalle cómo los tribunales llegaron a 1) trabajar a distancia, 2) celebrar audiencias por videoconferencia, 3) relacionarse con los usuarios a través de las redes sociales (es decir, Facebook y Chat Messenger), 4) emitir un espectáculo con jueces que responden a las preguntas de los usuarios a través de Facebook Live, y 5) grabar, transmitir y subir las audiencias judiciales a YouTube para cumplir con el requisito de publicidad de las audiencias penales. La digitalización de los tribunales durante la pandemia se caracteriza por una normatividad suspendida, que posibilita la innovación, pero presenta riesgos. Si bien las tecnologías digitales permitieron al poder judicial prestar servicios de forma continua, también crearon el riesgo de desplazar la normativa judicial y legal tradicional. Contribuyendo a la teoría de la innovación liminar y digitalización, Designing for Digital Justice teoriza cuatro fases: 1) la fase de pre-digitalización que da lugar al desarrollo de la regulación, 2) el hotspot de digitalización que da lugar a la ampliación de la regulación, 3) la innovación liminal que vuelve a desarrollar la regulación (pasando a una nueva fase preliminar), y 4) la permanencia de prácticas temporales que desplaza la regulación. Contribuyendo a la investigación sobre el diseño, Designing for Digital Justice ofrece nuevas posibilidades de intervención para el diseño de la justicia, conectando las tensiones y los niveles para intervenir en ellos. Los colegas investigadores encontrarán en estas páginas un sólido avance teórico en la intersección de la digitalización y la justicia y novedosas referencias metodológicas. Los profesionales se beneficiarán del marco de gobernanza Designing for Digital Justice Model, que ofrece tres campos de posibilidades de actuación para diseñar mejores sistemas de justicia. Sólo teniendo en cuenta las agencias digitales, jurídicas y sociales podremos diseñar mejores sistemas que se comprometan con el acceso a la justicia, el Estado de Derecho y, en última instancia, la paz social.

We analyze a decade of continuous Global Positioning System observations along the South American continent to estimate changes in deformation rates between the 2010 Maule (M8.8) and 2015 Illapel (M8.3) Chilean earthquakes. We find that surface velocities increased after the 2010 earthquake, in response to continental-scale viscoelastic mantle relaxation and to regional-scale increased degree of interplate locking. We propose that increased locking occurs transiently during a super-interseismic phase in segments adjacent to a megathrust rupture, responding to bending of both plates caused by coseismic slip and subsequent afterslip. Enhanced strain rates during a super-interseismic phase may therefore bring a megathrust segment closer to failure and possibly triggered the 2015 event.

We document changes in discharge in eight streams in Chile following two or more large earthquakes. In all cases, discharge increases. Changes in discharge occur for peak ground velocities greater than about 7-11cm/s. Above that threshold, the magnitude of both the increase in discharge and the total excess water do not increase with increasing peak ground velocities. While these observations are consistent with previous work in California, they conflict with lab experiments that show that the magnitude of permeability changes increases with increasing amplitude of ground motion. Instead, our study suggests that streamflow responses are binary. Plain Language Summary Earthquakes deform and shake the surface and the ground below. These changes may affect groundwater flows by increasing the permeability along newly formed cracks and/or clearing clogged pores. As a result, groundwater flow may substantially increase after earthquakes and remain elevated for several months. Here we document streamflow anomalies following multiple high magnitude earthquakes in multiple streams in one of the most earthquake prone regions worldwide, Chile. We take advantage of the dense monitoring network in Chile that recorded streamflow since the 1940s. We show that once a critical ground motion is exceeded, streamflow responses to earthquakes can be expected.

Die Colonia Dignidad (dt.: Kolonie der Würde) wurde 1961 von Mitgliedern einer deutschen Sekte im Zentrum des Landes, ca. 400 km südlich von Santiago entfernt, gegründet. Nach außen präsentierte sich die Gemeinschaft als glückliche und zufriedene deutsche Enklave, die ihre heimatlichen Traditionen und Bräuche im Ausland weiterhin pflegt. Mit dem Ende der Militärdiktatur unter Augusto Pinochet 1990 und dem damit verbundenen Wegfall der politischen Rückendeckung der Gemeinschaft, begann die chilenische Justiz die schon länger bestehenden Vorwürfe gegen den damaligen Sektenführer Paul Schäfer, u. a. wegen Kindesmissbrauchs und Folter an chilenischen Oppositionellen während der Militärdiktatur, zu untersuchen. Dem chilenischen Haftbefehl acht Jahre später entzog sich Paul Schäfer durch seine Flucht nach Argentinien. Die zurückbleibenden Mitglieder der Colonia Dignidad waren aufgrund des einsetzenden Zerfalls der alten Gemeinschaftsordnung gezwungen, sich ein neues Gemeinschaftskonzept zu erarbeiten, eines, in dem die bisher so dominante Führerfigur fehlte. Sowohl das Gemeinschaftsleben in der Colonia Dignidad zwischen 1961 und 1998 als auch das Zusammenleben in der heutigen Villa Baviera ab 1998 wird anhand der Theorien zur Gemeinschaftsforschung von Ferdinand Tönnies, Georg Vobruba, Zygmunt Baumann, Matthias Grundmann und Stephan Drucks analysiert. Im Findungsprozess eines neuen Gemeinschaftskonzeptes waren die Mitglieder der ehemaligen Colonia Dignidad gezwungen, sich mit der Vergangenheit auseinanderzusetzen. In diesem Zusammenhang wird der Frage nachgegangen, inwiefern eine Aufarbeitung der Vergangenheit (memoria) im kulturwissenschaftlichen und psychologischen Sinne stattfand bzw. stattfindet und wenn ja, wie sich diese gestaltete bzw. gestaltet. Hierzu wird untersucht, welche staatlichen Maßnahmen zur Unterstützung des Neuanfangs der Gemeinschaft getroffen wurden und welchen Erfolg diese Maßnahmen hatten. Basierend auf den daraus gewonnenen Resultaten und der aktuellen Selbstdarstellung der Villa Baviera in ihrer Webpräsenz, wird das neue Gemeinschaftskonzept der ehemaligen Colonia Dignidad auf die Chancen des Zusammenlebens hin analysiert. Weiterführend werden Konzepte zum kollektiven Gedächtnis untersucht, von dem „Familiengedächtnis“ auf ein „Gemeinschaftsgedächtnis“ übertragen und mit der Frage nach der konstruktiven memoria innerhalb der Villa Baviera verbunden. Abschließend wird der Frage nachgegangen, welche positiven Aspekte des Gemeinschaftslebens einer intentionalen Gemeinschaft auf das Gemeinschaftsleben der Villa Baviera übertragen werden könnten. N2 - This work analyzes the dangers and opportunities of communal living in exile using the example of the former Colonia Dignidad in Chile. Colonia Dignidad (Engl.: Colony of Dignity) was founded in 1961 by members of a German sect in the center of the country, about 400 km south of Santiago. To the outside world, the community presented itself as a happy and contented German enclave that continued to maintain its native traditions and customs abroad. With the end of the military dictatorship under Augusto Pinochet in 1990 and the associated loss of political backing for the community, the Chilean judiciary began to investigate the long-standing accusations against the then cult leader Paul Schäfer, including charges of child abuse and torture of Chilean opposition members during the military dictatorship. Paul Schäfer evaded the Chilean arrest warrant eight years later by fleeing to Argentina. As the old community order began to disintegrate, the members of Colonia Dignidad who remained behind were forced to devise a new community concept, one that lacked the leader figure who had been so dominant until then. Both the community life in Colonia Dignidad between 1961 and 1998 and the community life in today's Villa Baviera from 1998 onwards are analyzed on the basis of the theories of community research by Ferdinand Tönnies, Georg Vobruba, Zygmunt Baumann, Matthias Grundmann and Stephan Drucks. In the process of finding a new community concept, the members of the former Colonia Dignidad were forced to deal with the past. In this context, the question is examined to what extent a reappraisal of the past (memoria) in the cultural and psychological sense took place and, if so, how this took place. To this end, the study examines which state measures were taken to support the community's new beginning and what success these measures had. Based on the results obtained and the current self-representation of Villa Baviera in its web presence, the new community concept of the former Colonia Dignidad is analyzed in terms of the opportunities for living together. Further on, concepts of collective memory are examined, transferred from the "family memory" to a "community memory" and connected to the question of constructive memoria within Villa Baviera. Finally, the question is explored which positive aspects of the community life of an intentional community could be transferred to the community life of Villa Baviera.

A and B horizons increase in thickness and elemental depletion or enrichment increases from north (similar to 26 degrees S) to south (similar to 38 degrees S) in these horizons. Differences in the degree of chemical weathering, quantified by the chemical depletion fraction (CDF), are significant only between the arid and sparsely vegetated site and the other three sites. Differences in the CDF between the sites, and elemental depletion within the sites are sometimes smaller than the variations induced by the bedrock heterogeneity. Microbial abundances (bacteria and archaea) in saprolite substantially increase from the arid to the semi-arid sites. With this study, we provide a comprehensive dataset characterizing the Critical Zone geochemistry in the Chilean Coastal Cordillera. This dataset confirms climatic controls on weathering and denudation rates and provides prerequisites to quantify the role of biota in future studies.

As predicted, risky sexual scripts were linked to higher odds of perpetration through more risky sexual behavior cross-sectionally in both the Chilean and the Turkish sample and indirectly predicted perpetration 12 months later. High sexual self-esteem increased the likelihood of perpetration via higher initiation assertiveness in the Turkish sample only. High religiosity reduced the odds of perpetration through less risky sexual scripts and less risky sexual behavior in both samples. In addition, high religiosity increased the probability of perpetration through lower sexual self-esteem in the Turkish sample. Implications of these findings and the role of cultural factors contributing to the differential functioning of religiosity and sexual self-esteem are discussed.

Little research has been conducted on the prevalence of sexual aggression in developing countries, including Chile. This article presents the first systematic review of the evidence on the prevalence of sexual aggression victimization and perpetration among women and men in Chile. Furthermore, it reports differences in prevalence rates in relation to victim and perpetrator characteristics and victim–perpetrator relationships. A total of N = 28 studies were identified by a three-stage literature search, including the screening of academic databases, publications of Chilean institutions, and reference lists. A great heterogeneity was found for prevalence rates of sexual victimization, ranging between 1.0% and 51.9% for women and 0.4% and 48.0% for men. Only four studies provided perpetration rates, which varied between 0.8% and 26.8% for men and 0.0% and 16.5% for women. No consistent evidence emerged for differences in victimization rates in relation to victims’ gender, age, and education. Perpetrators were more likely to be persons known to the victim. Conceptual and methodological differences between the studies are discussed as reasons for the great variability in prevalence rates, and recommendations are provided for a more harmonized and gender-inclusive approach for future research on sexual aggression in Chile.

We evaluate the sediment flux response to the Maule earthquake in the Chilean Andes (Mw 8.8) using daily suspended sediment records from 31 river gauges. The catchments cover drainage areas of 350 to around 10,000 km(2), including a wide range of topographic slopes and vegetation cover of the Andean western flank. We compare the 3- to 8-year postseismic record of sediment flux to each of the following preseismic periods: (1) all preseismic data, (2) a 3-year period prior to the seismic event, and (3) the driest preseismic periods, as drought conditions prevailed in the postseismic period. Following the earthquake, no increases in suspended sediment flux were observed for moderate to high percentiles of the streamflow distribution (mean, median, and >= 75th percentile). However, more than half of the examined stations showed increased sediment flux during baseflow. By using a Random Forest approach, we evaluate the contributions of seismic intensities, peak ground accelerations, co-seismic landslides, hydroclimatic conditions, topography, lithology, and land cover to explain the observed changes in suspended sediment concentration and fluxes. We find that the best predictors are hillslope gradient, low-vegetation cover, and changes in streamflow discharge. This finding suggests a combined first-order control of topography, land cover, and hydrology on the catchment-wide erosion response. We infer a reduced sediment connectivity due to the postseismic drought, which increased the residence time of sediment detached and remobilized following the Maule earthquake.
