Violencia física y efectos simbólicos. El caso de Tres Arroyos a fines del siglo XIX y principios del XX

En este trabajo se busca analizar aquellas presentaciones de las mujeres ante las autoridades judiciales de Tres Arroyos, un pueblo de reciente formación en el sur de la provincia de Buenos Aires, para denunciar la violencia a la que se veían expuestas, entre 1889 y 1904. Pretendemos encarar el tema con un enfoque que combine lo específicamente jurídico con una mirada de género y los aspectos culturales y sociales. Pretendemos adentrarnos en el valor simbólico de las situaciones de violencia en sí mismas, así como de su denuncia y exposición pública. En síntesis, lo que interesa es focalizar en el componente simbólico de algunas de estas acciones que, mas allá de las situaciones concretas que traslucen, tienen un fondo de racionalidad, comunican algo a una sociedad y, en algún punto, pretenden imponer o restaurar un orden.

Agenda y Cuaderno de Nueva York : La paradoja entre la identidad íntima y la máscara múltiple

José Hierro es recordado en la historia de la literatura española por la poetización en sus obras de posguerra de un claro yo autoral, que cobra sentido casi siempre en cuanto englobado en el nosotros de una generación concreta y real: los textos hierrianos dan la impresión de estar hablando siempre en clave personal, si bien las confesiones se quedan muchas veces en el ámbito de lo público, raras veces sumergiéndose en la introspección de lo íntimo, esfera que, como es sabido, el poeta solía respetar con abundante prudencia en todos los aspectos de su vida. Todo ello se construye con las oportunas marcas de realismo o realemas, que conducen al lector en la pista de una lectura más o menos realista, tendente a eliminar todo efecto de ficción, como era canónico en la época. La evolución de José Hierro le lleva a ir dejando de lado esta poética de razón histórica para adentrarse en otros caminos, que serían tan exitosos y productivos en los años subsiguientes. No es sorprendente, por tanto, que encontremos líneas evolutivas en un autor de cuya obra se extiende en tan largo período de tiempo -pensemos que se trata de más de cincuenta años-. Sin embargo, sí llama la atención que en sus últimos libros de poesía encontremos una peculiar manera de resolver el problema del pudor y de la identidad. Encontramos en ellos la imbricación de una creciente confesión íntima y un decreciente correlato autorial. No somos las primeras en advertir esta aparente paradoja, pero lo que queremos demostrar es que las frecuentes máscaras culturalistas ejercen una función múltiple en la obra hierriana; permitiéndole conectar con las jóvenes poéticas, el autor consigue dar cabida a las inquietudes íntimas sin sentirse violentado

Las huelgas de los estibadores portuarios en el sur santafesino en 1928

El 2 de mayo de 1928 se inicia una huelga de estibadores portuarios en Rosario después de años de tibia actividad sindical. Días más tarde, varios hechos de sangre provocaron la solidaridad obrera con dos paros generales que conmovieron a la ciudad por su agitación y violencia. Los portuarios villenses también se solidarizaron y, un mes más tarde, encabezaron un violento reclamo laboral. El motivo inicial de las huelgas fue el salarial, pero la cuestión de fondo que hilvana a ambas experiencias es la puja social por el deterioro de las condiciones laborales y las imposiciones empresarias en el control y selección de la fuerza de trabajo.En principio la espontaneidad de la protesta tomó por sorpresa a las organizaciones sindicales de izquierda que durante la década del 20 habían mostraban varias fracturas, no obstante será la oportunidad que explica la reorganización y difusión del movimiento obrero con posterioridad. En otro sentido, los conflictos en Rosario y Villa Constitución reflejan la compleja trama de la política santafesina y su conexión con el ámbito laboral. Asimismo, creemos que los sucesos de 1928 tienen una repercusión mayor que la estrictamente local engarzándose en un ciclo de conflictividad que involucra a buena parte de la economía agroexportadora

La fertilidad de la derrota : Identidades de frontera en Fuego en Casabindo de Héctor Tizón

Fuego en Casabindo ficcionaliza desviaciones del regionalismo argentino a partir de una programática ubicación fronteriza, geográfica y literaria, que sustenta la indagación de identidades íntimas y colectivas, complejizando las construcciones de la memoria. Ante el quiebre entre un pasado épico y un presente árido de futuro, la ficción opta por la frontera y el reconocimiento presente del otro, afirmándose como cultura de un mundo derrotado. La reconstrucción de acontecimientos violentos de la historia argentina, desde versiones orales tamizadas por una cosmovisión mítica, conforma el relato de silenciosos derrotados, fragmentados en identidades agonizantes revitalizadas por una literatura absuelta de residuos regionalistas

Violencia y poder : Crímenes sexuales en Buenos Aires, 1850-1860

Este trabajo busca introducir al lector en una problemática tan antigua como actual: el de los crímenes sexuales, proponiéndo un acercamiento múltiple desde la visión jurídica y la social, desde las víctimas y su familia. Nos hemos concentrado especialmente en tratar de observar la violencia sexual jurídica que define a la víctima según su sexo, "cualidad moral" y el acto que se cometiera sobre ella, que le niega el derecho a reclamar, adoctrinando en el silencio como mejor opción que la denuncia. También nos propusimos mostrar como hay personas que desafiando este "disciplinamiento" busca el castigo del o los culpables del delito sabiendo sin embargo que existe un precio muy alto que pagar por ello: la deshonra pública de una hija o hijo

Thomas Hobbes : Sobre el miedo

Este trabajo pretende echar cierta luz sobre el papel del miedo en el pensamiento político de Hobbes. Sabido es que esta pasión subyace al contrato social, en el sentido de que impulsa al hombre a abandonar el estado de naturaleza a fin de encontrar seguridad y de deshacerse de la amenaza de la muerte violenta. Teniendo en cuenta que el miedo y la muerte son inseparables en la filosofía de Hobbes, surge una pregunta fundamental: ¿hasta qué punto podemos decir que el miedo desaparece completamente después del contrato social? En Hobbes, el miedo parecería ser una característica intrínseca del hombre.

Sediment facies of the Indian-Pakistan continental margin, Indian Ocean Expedition

The studies described here base mainly on sedimentary material collected during the "Indian Ocean Expedition" of the German research vessel "Meteor" in the region of the Indian-Pakistan continental margin in February and March 1965. Moreover,samples from the mouth of the Indus-River were available, which were collected by the Pakistan fishing vessel "Machhera" in March 1965. Altogether, the following quantities of sedimentary material were collected: 59.73 m piston cores. 54.52 m gravity cores. 33 box grab samples. 68 bottom grab samples Component analyses of the coarse fraction were made of these samples and the sedimentary fabric was examined. Moreover, the CaCO3 and Corg contents were discussed. From these investigations the following history of sedimentation can be derived: Recent sedimentation on the shelf is mainly characterized by hydrodynamic processes and terrigenous supply of material. In the shallow water wave action and currents running parallel to the coast, imply a repeated reworking which induces a sorting of the grains and layering of the sediments as well as a lack of bioturbation. The sedimentation rate is very high here. From the coast-line down to appr. 50 m the sediment becomes progressively finer, the conditions of deposition become less turbulent. On the outer shelf the sediment is again considerably coarser. It contains many relicts of planktonic organisms and it shows traces of burrowing. Indications for redeposition are nearly missing, a considerable part of the fine fraction of the sediments is, however, whirled up and carried away. In wide areas of the outer shelf this stirring has gained such a degree that recent deposits are nearly completely missing. Here, coarse relict sands rich in ooids are exposed, which were formed in very shallow stirred water during the time when the sea reached its lowest level, i.e. at the turn of the Pleistocene to the Holocene. Below the relict sand white, very fine-grained aragonite mud was found at one location (core 228). This aragonite mud was obviously deposited in very calm water of some greater depth, possibly behind a reef barrier. Biochemic carbonate precipitation played an important part in the formation of relict sands and aragonite muds. In postglacial times the relict sands were exposed for long periods to violent wave action and to areal erosion. In the present days they are gradually covered by recent sediments proceeding from the sides. On the continental margin beyond the shelf edge the distribution of the sediments is to a considerable extent determined by the morphology of the sea bottom. The material originating from the continent and/or the shelf, is less transported by action of the water than by the force of gravity. Within the range of the uppermost part of the continental slope recent sedimentation reaches its maximum. Here the fine material is deposited which has been whirled up in the zone of the relict sands. A laminated fine-grained sediment is formed here due to the very high sedimentation rate as well as to the extremely low O2-content in the bottom water, which prevents life on the bottom of the sea and impedes thus also bioturbation. The lamination probaly reflects annual variation in deposition and can be attributed to the rhythm of the monsoon with its effects on the water and the weather conditions. In the lower part of the upper continental slope sediments are to be found which show in varying intensity, intercalations of fine material (silt) from the shelf, in large sections of the core. These fine intercalations of allochthonous material are closely related to the autochthonous normal sediment, so that a great number of small individual depositional processes can be inferred. In general the intercalations are missing in the uppermost part of the cores; in the lower part they can be met in different quantities, and they reach their maximum frequency in the upper part of the lower core section. The depositions described here were designated as turbid layer sediments, since they get their material from turbid layers, which transport components to the continental slope which have been whirled up from the shelf. Turbidites are missing in this zone. Since the whole upper continental slope shows a low oxygen-content of the bottom water the structure of the turbid layer sediments is more or less preserved. The lenticular-phacoidal fine structure does, however, not reflect annual rhythms, but sporadic individual events, as e.g. tsunamis. At the lower part of the continental slope and on the continental rise the majority of turbidites was deposited, which, during glacial times and particularly at the beginning of the post-glacial period, transported material from the zone of relict sands. The Laccadive Ridge represented a natural obstacle for the transport of suspended sediments into the deep sea. Core SIC-181 from the Arabian Basin shows some intercalations of turbidites; their material, however, does not originate from the Indian Shelf, but from the Laccadive Ridge. Within the range of the Indus Cone it is surprising that distinct turbidites are nearly completely missing; on the other hand, turbid layer sediments are to be found. The bottom of the sea is showing still a slight slope here, so that the turbidites funneled through the Canyon of the Swatch probably rush down to greater water depths. Due to the particularly large supply of suspended material by theIndus River the turbid layer sediments show farther extension than in other regions. In general the terrigenous components are concentrated on the Indus Cone. It is within the range of the lower continental slope that the only discovery of a sliding mass (core 186) has been located. It can be assumed that this was set in motion during the Holocene. During the period of time discussed here the following development of kind and intensity of the deposition of allochthonous material can be observed on the Indian-Pakistan continental margin: At the time of the lowest sea level the shelf was only very narrow, and the zone in which bottom currents were able to stir up material by oscillating motion, was considerably confined. The rivers flowed into the sea near to the edge of the shelf. For this reason the percentage of terrigenous material, quartz and mica is higher in the lower part of many cores (e.g. cores 210 and 219) than in the upper part. The transition from glacial to postglacial times caused a series of environmental changes. Among them the rise of the sea level (in the area of investigation appr. 150 m) had the most important influence on the sedimentation process. In connection with this event many river valleys became canyons, which sucked sedimentary material away from the shelf and transported it in form of turbidites into the deep sea. During the rise of the sea level a situation can be expected with a maximum area of the comparatively plane shelf being exposed to wave action. During this time the process of stirring up of sediments and formation of turbid layers will reach a maximum. Accordingly, the formation of turbidites and turbid layer sediments are most frequent at the same time. This happened in general in the older polstglacial period. The present day high water level results in a reduced supply of sediments into the canyons. The stirring up of sediments from the shelf by wave action is restricted to the finest material. The missing of shelf material in the uppermost core sections can thus be explained. The laminated muds reflect these calm sedimentation conditions as well. In the southwestern part of the area of investigation fine volcanic glass was blown in during the Pleistocene, probably from the southeast. It has thus become possible to correlate the cores 181, 182, 202. Eolian dust from the Indian subcontinent represents probably an important component of the deep sea sediments. The chemism of the bottom as well as of the pore water has a considerable influence on the development of the sediments. Of particular importance in this connection is a layer with a minimum content of oxygen in the sea water (200-1500 m), which today touches the upper part of the continental slope. Above and beyond this oxygen minimum layer somewhat higher O2-values are to be observed at the sea bottom. During the Pleistocene the oxygen minimum layer has obviously been locatedin greater depth as is indicated by the facies of laminated mud occuring in the lower part of core 219. The type of bioturbation is mainly determined by the chemism. Moreover, the chemism is responsible for a considerable selective dissolution, either complete or partial, of the sedimentary components. Within the range of the oxygen minimum layer an alkaline milieu is developed at the bottom. This causes a complete or partial dissolution of the siliceous organisms. Here, bioturbation is in general completely missing; sometimes small pyrite-filled burrowing racks are found. In the areas rich in O2 high pH-values result in a partial dissolution of the calcareous shells. Large, non-pyritized burrowing tracks characterize the type of bioturbation in this environment. A study of the "lebensspuren" in the cores supports the assumption that, particularly within the region of the Laccadive Basin, the oxygen content in the bottom sediments was lower than during the Holocene. This may be attributed to a high sedimentation rate and to a lower O2-content of the bottom water. The composition of the allochthonous sedimentary components, detritus and/or volcanic glass may locally change the chemism to a considerable extent for a certain time; under such special circumstances the type of bioturbation and the state of preservation of the components may be different from those of the normal sediment.

Trioctahedral micas in xenolithic ejecta from recent volcanism of the Somma-Vesuvius

This study reports the first crystal chemical database resulting from a detailed structural investigation of trioctahedral micas found in xenolithic ejecta produced during the AD 1631, 1872 and 1944 eruptions, three explosive episodes of recent volcanic period of Vesuvius volcano (Southern Italy). Three xenolith types were selected: metamorphic/metasomatic skarns, pyrometamorphic/hydrothermally altered nodules and mafic cumulates. They are related to different magma chemistry and effusive styles: from sub-plinian and most evolved (AD 1631 eruption) to violent strombolian with medium evolution degree (AD 1872 eruption) to vulcanian-effusive, least evolved (AD 1944 eruption) event, respectively. Both xenoliths and micas were investigated employing multiple techniques: the xenoliths were characterized by X-ray fluorescence, inductively-coupled plasma-mass spectrometry, optical microscopy, X-ray powder diffraction, and quantitative energy-dispersive microanalysis; the micas were studied by electron probe microanalysis and single crystal X-ray diffraction. The mica-bearing xenoliths show variable texture and mineralogical assemblage, clearly related to their different origin. Based on the major oxide chemistry, only one xenolithic sample falls in the skarn compositional field from the Somma-Vesuvius literature, some fall close to the skarns and cumulate fields, others plot close to the syenite/foidolite/essexite field. A subgroup of the selected ejecta does not fall or approach any of the compositional fields. Trace and rare earth element patterns show some petrological affinity between studied xenoliths and erupted magmas with typical Eu, Ta and Nb negative anomalies. Strongly depleted patterns were detected for the 1631 metamorphic/metasomatic skarns xenoliths. Three distinct mica groups were distinguished: 1) Mg-, Al-rich, low Ti-bearing, low to moderate F-bearing varieties (1631 xenolith), 2) Al-moderate, F- and Mg-rich, Ti-, Fe-poor varieties (1872 xenolith), and 3) Al-, Ti- and Fe-rich, F-poor phases (1944 xenolith). All the analysed mica crystals are 1M polytypes with the expected space group C2/m. Micas from xenoliths of the 1631 Vesuvius eruption are phlogopites characterized by a combination of low extent of oxy-type and variable extent OH-F-substitutions, as testified by the range of F concentration (from ~ 0.20 to 0.80 apfu). Micas from xenoliths of the 1872 Vesuvius eruption exhibit structural peculiarities typical of fluorophlogopites, i.e. OH-F-substitution is predominant. Micas from the xenolith of the 1944 Vesuvius eruption display features typical of oxy-substituted micas. The variability of the crystal chemical features of the studied micas are consistent with the remarkable variation of their host rocks. Micas from 1631 nodules are related to metasomatic, skarn-type environment, deriving from the metamorphosed wall-rocks hosting the magma reservoir. The fluorophlogopites from the 1872 xenoliths testify for strongly dehydrated environmental conditions compared to those of the 1631 and 1944 hosts. Finally, magma storage condition at depth, associated to a decreasing aH2O may have promoted major oxy-type substitutions in 1944 biotites.

Nature, chemistry, and origin of late Cenozoic megascopic tephras in Legs 89 and 90 Cores from the Southwest Pacific

Several thin (1-10 cm) megascopic vitric tephras occur in the late Cenozoic calcareous oozes on Lord Howe Rise in the Tasman Sea and off eastern South Island, New Zealand. Of the 18 tephras analyzed 15 are silicic (75-78% SiO2) with abundant clear glass shards and a biotite ± hypersthene ± green hornblende ferromagnesian mineralogy. The Neogene silicic tephras were derived from the now-extinct Coromandel volcanic area in New Zealand, and the Quaternary ones from the presently active Central Volcanic Region of New Zealand. On the basis of glass chemistry and age, several of the Quaternary tephras are probably correlatives, and at least two can be matched to the major on-land Mt. Curl tephra (-0.25 m.y.). The occurrence of correlative silicic tephras both northwest and southeast of New Zealand may result from particularly violent eruptions, the ash below and above an altitude of -20 km being dispersed in opposite directions toward the Pacific Ocean and Tasman Sea, respectively. Ash drifting eastward into the southeasterly trade wind belt off northeastern New Zealand could also be carried into the central and northern Tasman Sea. Three megascopic tephras consist of altered basic shards and common labradorite crystals. They record Neogene explosive basaltic to andesitic activity from nearby ocean island or ridge sources in the Ontong-Java Plateau and Vanuatu regions. The megascopic tephras are a very incomplete and biased record of late Cenozoic explosive volcanism in the southwest Pacific because the innumerable, thin, green argillaceous layers in the cores (Gardner et al., this volume) probably represent devitrified intermediate to basic tephras derived mainly from oceanic arc volcanism along the Pacific/Australia plate boundary. In contrast to the New Zealand-derived silicic glass shards, the preservation potential of these more basic shards in Leg 90 calcareous sediments was low.

Democratizing Indonesia: Reformasi Period in Historical Perspective

Introduction : Triggered by the Asian currency crisis, Indonesia plunged into the times of violent change. With the downfall of the long-standing Soeharto rule in May 1998, changes of　the state order started with great magnitude and rapidity under a new banner of　“reformasi” (reform). What changes have occurred in this reformasi period? What do　these changes signify? To answer these questions, it would be better to have a certain　yardstick to allow us comparison. One possibility is to use a yardstick of history. What　picture will emerge if we see the current array of changes in long-term historical　perspectives is a main question of this paper. This paper intends to provide a bird’s-eye picture illustrating where in the Indonesian history the current restructuring of the state order is located. Rather than focusing on a specific area, I here attempt to broaden our outlook on Indonesia’s political, economic and social arenas in order to identify what are happening in these arenas, how they are mutually related, and what those events signify in the Indonesia’s historical context.

Features of Land Conflicts in Post Civil War Rwanda

Land conflicts in Rwanda have attracted particular attention because they have both environmental and political causes. This paper attempts to shed light on the nature of land conflicts in present-day Rwanda based on popular justice records and interviews collected in two rural areas. From the analyses of these data, two types of land confl ict can be distinguished. The first type consists of those among family members. Given that land is the most important asset for ordinary rural households, its inheritance often brings about conflicts between right-holders. Those of the second type are triggered by political change. Impacts of the two national-level violent conflicts in Rwanda, the “social revolution” just before independence and the civil war in the 1990s, are of tremendous significance in this context. The military victory of the former rebels in 1994 caused a massive return of Tutsi refugees, who were officially permitted to acquire land from the original inhabitants. Although no serious protestation against this policy has occurred thus far, it has produced various land conflicts. Dealing with potential grievances among original inhabitants is an important challenge for the present government.

From authoritarianism to upheaval : the political economy of the Syrian uprising and regime persistence

The ensuing bloodshed and deteriorating humanitarian crisis in Syria, the failure of the United Nations Security Council to reach a consensus on what action to take, and the involvement of contending external actors partially reflect the complexity of the current impasse. Despite the importance of regional and international factors, however, this papers attempts to argue that the domestic dynamics of the Syrian crisis have been vitally important in determining the course of the popular uprising and the regime’s response. In this, Syria’s crisis belongs with the Arab Spring the trajectories and prospects of which have been shaped by dynamics within regimes. It will be seen that the formal and informal institutional structure of the Ba‘thist regime in Syria has been critical to its resilience and ability to stay united so far while attempting to crush a peaceful popular uprising that turned into insurgency in the face of the regime’s violent crackdown.

Trajectories and outcomes of the 'Arab Spring' : comparing Tunisia, Egypt, Libya and Syria

Almost three years have passed since the 'Arab Spring' began in late 2010. In the major sites of popular uprisings, political conditions remain unsettled or violent. Despite similarities in their original opposition to authoritarian rule, the outcomes differed from country to country. In Tunisia and Egypt, processes of transiting from authoritarian rule produced contrasting consequences for democratic politics. Uprisings led to armed rebellion in Libya and Syria, but whereas Gaddafi was overthrown, Asad was not. What explains the different trajectories and outcomes of the Arab Spring? How were these shaped by the power structure and levels of social control of the pre-uprising regimes and their state institutions, on the one hand, and by the character of the societies and oppositional forces that rose against them? Comparing Tunisia with Egypt, and Libya with Syria, this paper discusses various factors that account for variations in the trajectories and outcomes of the Arab Spring, namely, the legacy of the previous regime, institutional and constitutional choices during "transition" from authoritarian rule, socioeconomic conditions, and the presence of absence of ethnic, sectarian and geographic diversity.

Shower approach in the simulation of ion scattering from solids

An efficient approach for the simulation of ion scattering from solids is proposed. For every encountered atom, we take multiple samples of its thermal displacements among those which result in scattering with high probability to finally reach the detector. As a result, the detector is illuminated by intensive “showers,” where each event of detection must be weighted according to the actual probability of the atom displacement. The computational cost of such simulation is orders of magnitude lower than in the direct approach, and a comprehensive analysis of multiple and plural scattering effects becomes possible. We use this method for two purposes. First, the accuracy of the approximate approaches, developed mainly for ion-beam structural analysis, is verified. Second, the possibility to reproduce a wide class of experimental conditions is used to analyze some basic features of ion-solid collisions: the role of double violent collisions in low-energy ion scattering; the origin of the “surface peak” in scattering from amorphous samples; the low-energy tail in the energy spectra of scattered medium-energy ions due to plural scattering; and the degradation of blocking patterns in two-dimensional angular distributions with increasing depth of scattering. As an example of simulation for ions of MeV energies, we verify the time reversibility for channeling and blocking of 1-MeV protons in a W crystal. The possibilities of analysis that our approach offers may be very useful for various applications, in particular, for structural analysis with atomic resolution.

Comparison of experimental and numerical sloshing loads in partially filled tanks

Sloshing describes the movement of liquids inside partially filled tanks, generating dynamic loads on the tank structure. The resulting impact pressures are of great importance in assessing structural strength, and their correct evaluation still represents a challenge for the designer due to the high level of nonlinearities involved, with complex free surface deformations, violent impact phenomena and influence of air trapping. In the present paper, a set of two-dimensional cases, for which experimental results are available, is considered to assess the merits and shortcomings of different numerical methods for sloshing evaluation, namely two commercial RANS solvers (FLOW-3D and LS-DYNA), and two academic software (Smoothed Particle Hydrodynamics and RANS). Impact pressures at various critical locations and global moment induced by water motion in a partially filled rectangular tank, subject to a simple harmonic rolling motion, are evaluated and predictions are compared with experimental measurements. 2012 Copyright Taylor and Francis Group, LLC.
