Several publications have contributed to improve the stratigraphy of the Paraíba Basin in northeastern Brazil. However, the characterization and distribution of sedimentary units in onshore areas of this basin are still incomplete, despite their significance for reconstructing the tectono-sedimentary evolution of the South American passive margin. This work provides new information to differentiate among lithologically similar strata, otherwise entirely unrelated in time. This approach included morphological, sedimentological and stratigraphic descriptions based on surface and sub-surface data integrated with remote sensing, optically stimulated luminescence dating, U+Th/He dating of weathered goethite, and heavy mineral analysis. Based on this study, it was possible to show that Cretaceous units are constrained to the eastern part of the onshore Paraíba Basin. Except for a few outcrops of carbonatic rocks nearby the modern coastline, deposits of this age are not exposed to the surface in the study area. Instead, the sedimentary cover throughout the basin is constituted by mineralogically and chronologically distinctive deposits, inserted in the Barreiras Formation and mostly in the Post-Barreiras Sediments, of early/middle Miocene and Late Pleistocene-Holocene ages, respectively. The data presented in this work support tectonic deformation as a factor of great relevance to the distribution of the sedimentary units of the Paraíba Basin.

Il lavoro di Elisa Tosi Brandi riguarda il mestiere del sarto nel basso Medioevo e si sviluppa utilizzando due prospettive differenti. Da un lato, infatti, si è deciso di seguire una tradizione di studi oramai consolidata, che privilegia l’indagine degli aspetti economici e politici, dall’altro si è scelto di non trascurare la storia dei prodotti degli artigiani. L’approccio utilizzato in questa tesi tiene insieme entrambe le prospettive di ricerca, tentando dunque di indagare i produttori e i prodotti così come le fasi e i metodi di lavoro. Ciò senza ignorare, da un lato, indagini di tipo politico, economico e sociale, poiché tali oggetti sono lo specchio della società che li ha ideati e creati e da cui non si può prescindere e, dall’altro, indagini di tipo tecnico, poiché gli oggetti sono rivelatori del complesso patrimonio di conoscenze artigianali. Partendo dal caso di studio della Società dei sarti della città di Bologna, la tesi di Elisa Tosi Brandi ricostruisce questo mestiere confrontando tra loro fonti inedite (statuti corporativi, matricole, estimi) e studi effettuati su altre aree italiane. La ricca documentazione conservata ha consentito di mettere in luce l’organizzazione di questo lavoro, di collocare abitazioni e botteghe nell’area del mercato e nel più ampio tessuto cittadino, di individuare i percorsi commerciali e di approvvigionamento. L’ultima parte della tesi offre l’analisi di alcune fonti materiali al fine di ricostruire le tecniche sartoriali medievali intrecciando tutte le fonti consultate: dai documenti scritti si passa pertanto agli abiti che offrono informazioni dirette sulle tecniche di taglio ed assemblaggio.

La ricerca pone al centro dell’indagine lo studio dell’importanza del cibo nelle cerimonie nuziali dell’Europa occidentale nei secoli V-XI. Il corpus di fonti utilizzate comprende testi di genere diverso: cronache, annali, agiografie, testi legislativi, a cui si è aggiunta un’approfondita analisi delle antiche saghe islandesi. Dopo un'introduzione dedicata in particolare alla questione della pubblicità della celebrazione, la ricerca si muove verso lo studio del matrimonio come “processo” sulla base della ritualità alimentare: i brindisi e i banchetti con cui si sigla l’accordo di fidanzamento e i ripetuti convivi allestiti per celebrare le nozze. Si pone attenzione anche ad alcuni aspetti trasversali, come lo studio del caso della “letteratura del fidanzamento bevuto”, ossia una tradizione di testi letterari in cui il fidanzamento tra i protagonisti viene sempre ratificato con un brindisi; a questo si aggiunge un’analisi di stampo antropologico della "cultura dell’eccesso", tipica dei rituali alimentari nuziali nel Medioevo, in contrasto con la contemporanea "cultura del risparmio". L'analisi si concentra anche sulle reiterate proibizioni al clero, da parte della Chiesa, di partecipare a banchetti e feste nuziali, tratto comune di tutta l’epoca altomedievale. Infine, la parte conclusiva della ricerca è incentrata sulla ricezione altomedievale di due figure bibliche che pongono al centro della narrazione un banchetto nuziale: la parabola delle nozze e il banchetto di Cana. L’insistente presenza di questi due brani nelle parole dei commentatori biblici mostra la straordinaria efficacia del “linguaggio alimentare”, ossia di un codice linguistico basato sul cibo (e su contesti quali l’agricoltura, la pesca, ecc.) come strumento di comunicazione sociale di massa con una valenza antropologica essenzialmente universale.

At the end of the middle Ages, financial savings institutions developed, largely in response to the increasingly usurious money-lending practices of the Jews and to the adaptation of church authorities to the by then well developed commercial and financial operations. It was the Franciscan Order that took the initiative to develop such institutions, first in Italy and later in other western European Mediterranean towns. These were the so-called Monte di Pieta, which lent money at low rates of interest taking objects in pawn as security. However, as they had to operate with circulating capital and on the principles of savings banks, they may be considered to be the predecessors of modern banks. Although charity was declared in the very names of these institutions, this was no longer in the sense of the medieval mercy towards the virtuous poor, but more a support for impoverished members of higher social strata, as loan applicants had to place valuable movable property in pawn, meaning that they first had to possess such property. In spite of this, the institutions had the character of the primeval accumulation of capital, although not so much for individuals as for a community or, in the latter's name, for a commune, i.e. the local authority, which at least in the cases of Koper and Piran was also the founder. However, the stagnation of trade with the hinterland and the decline in the economic power of the Venetian Republic, particularly in the late 17th and early 18th centuries, pushed pawnshops into a more miserable existence, with ups and downs linked with the irregularities of profit-making on behalf of the institution, particularly by its clerks.

This project considered the development of municipal self-government (particularly the Magdeburg-law type) in Ukraine through the late Middle Ages in the context of central and eastern European history, using a comparative analysis of different forms of self-government. The Magdeburg Law was brought to the lands of old Rus by German colonists in the period of the Galician-Volhynian State (in the late 13th-early 14th centuries). Municipal self-government based on this law in Ukraine was now however an external artificial phenomenon, but rather an intrinsic need that emerged during the historical development of the society. The Magdeburg Law reached Ukraine through Poland and acquired certain features which were different from the form used in German towns, and Ukrainian towns further adapted the Magdeburg model to their own circumstances. It was "purest" in the western part of the region, while further to the east Magdeburg-Law-type municipal government appeared later, was further removed from its original form, and had a weaker influence on the historical development of the towns. The Magdeburg Law came to be a legalisation of a historically determined process of the emergence of an urban estate.

Only a few sites in the Alps have produced archaeological finds from melting ice. To date, prehistoric finds from four sites dating from the Neolithic period, the Bronze Age, and the Iron Age have been recovered from small ice patches (Schnidejoch, Lötschenpass, Tisenjoch, and Gemsbichl/Rieserferner). Glaciers, on the other hand, have yielded historic finds and frozen human remains that are not more than a few hundred years old (three glacier mummies from the 16th to the 19th century and military finds from World Wars I and II). Between 2003 and 2010, numerous archaeological finds were recovered from a melting ice patch on the Schnidejoch in the Bernese Alps (Cantons of Berne and Valais, Switzerland). These finds date from the Neolithic period, the Early Bronze Age, the Iron Age, Roman times, and the Middle Ages, spanning a period of 6000 years. The Schnidejoch, at an altitude of 2756 m asl, is a pass in the Wildhorn region of the western Bernese Alps. It has yielded some of the earliest evidence of Neolithic human activity at high altitude in the Alps. The abundant assemblage of finds contains a number of unique artifacts, mainly from organic materials like leather, wood, bark, and fibers. The site clearly proves access to high-mountain areas as early as the 5th millennium BC, and the chronological distribution of the finds indicates that the Schnidejoch pass was used mainly during periods when glaciers were retreating.

Archaeological finds from Schnidejoch (2756 m a.s.l.) and Lötschenpass (2690 m a.s.l.) cover the periods from the Early Neolithic to the Middle Ages (4800 BC - 1000 AD). The numerous finds from Schnidejoch discovered since 2003 can now be seen in relationship with Neolithic and Bronze Age settlements in the Rhone valley and together with the early use of alpine meadows and early transhumance. Finds of Early Bronze Age bows from Lötschenpass go back to the 1930ies. New finds of wooden objects and objects made from birch bark melted out from the ice in the summer of 2011. The lecture presents these new finds and an actualized view of Schnidejoch finds.

The heat of summer 2003 in Western and Central Europe was claimed to be unprecedented since the Middle Ages on the basis of grape harvest data (GHD) and late wood maximum density (MXD) data from trees in the Alps. This paper shows that the authors of these studies overlooked the fact that the heat and drought in Switzerland in 1540 likely exceeded the amplitude of the previous hottest summer of 2003, because the persistent temperature and precipitation anomaly in that year, described in an abundant and coherent body of documentary evidence, severely affected the reliability of GHD and tree-rings as proxy-indicators for temperature estimates. Spring–summer (AMJJ) temperature anomalies of 4.7 °C to 6.8 °C being significantly higher than in 2003 were assessed for 1540 from a new long Swiss GHD series (1444 to 2011). During the climax of the heat wave in early August the grapes desiccated on the vine, which caused many vine-growers to interrupt or postpone the harvest despite full grape maturity until after the next spell of rain. Likewise, the leaves of many trees withered and fell to the ground under extreme drought stress as would usually be expected in late autumn. It remains to be determined by further research whether and how far this result obtained from local analyses can be spatially extrapolated. Based on the temperature estimates for Switzerland it is assumed from a great number of coherent qualitative documentary evidence about the outstanding heat drought in 1540 that AMJJ temperatures were likely more extreme in neighbouring regions of Western and Central Europe than in 2003. Considering the significance of soil moisture deficits for record breaking heat waves, these results still need to be validated with estimated seasonal precipitation. It is concluded that biological proxy data may not properly reveal record breaking heat and drought events. Such assessments thus need to be complemented with the critical study of contemporary evidence from documentary sources which provide coherent and detailed data about weather extremes and related impacts on human, ecological and social systems.

The palynostratigraphy of two sediment cores from Soppensee, Central Switzerland (596 m asl) was correlated with nine regional pollen assemblage zones defined for the Swiss Plateau. This biostratigraphy shows that the sedimentary record of Soppensee includes the last 15 000 years, i.e. the entire Late-glacial and Holocene environmental history. The vegetation history of the Soppensee catchment was inferred by pollen and plant-macrofossil analyses on three different cores taken in the deepest part of the lake basin (27 m). On the basis of a high-resolution varve and calibrated radiocarbonchronology it was possible to estimate pollen accumulation rates, which together with the pollen percentage data, formed the basis for the interpretation of the past vegetation dynamics. The basal sediment dates back to the last glacial. After reforestation with juniper and birch at ca. 12 700 B.P., the vegetation changed at around 12 000 B.P. to a pine-birch woodland and at the onset of the Holocene to a mixed deciduous forest. At ca. 7000 B.P., fir expanded and dominated the vegetation with beech becoming predominant at ca. 50014C-years later until sometime during the Iron Age. Large-scale deforestation, especially during the Middle Ages, altered the vegetation cover drastically. During the Late-glacial period two distinct regressive phases in vegetation development are demonstrated, namely, the Aegelsee oscillation (equivalent to the Older Dryas biozone) and the Younger Dryas biozone. No unambiguous evidence for Holocene climatic change was detected at Soppensee. Human presence is indicated by early cereal pollen and distinct pulses of forest clearance as a result of human activity can be observed from the Neolithic period onwards.

Ocean Drilling Program Leg 167 represents the first time since 1978 that the North American Pacific margin was drilled to study ocean history. More than 7500 m of Quaternary to middle Miocene (14 Ma) sediments were recovered from 13 sites, representing the most complete stratigraphic sequence on the California margin. Diatoms are found in most samples in variable abundance and in a moderately well-preserved state throughout the sequence, and they are often dominated by robust, dissolution-resistant species. The Neogene North Pacific diatom zonation of Yanagisawa and Akiba (1998, doi:10.5575/geosoc.104.395) best divides the Miocene to Quaternary sequences, and updated ages of diatom biohorizons estimated based on the geomagnetic polarity time scale of Cande and Kent (1995, doi:10.1029/94JB03098) are slightly revised to adjust the differences between the other zonations. Most of the early middle Miocene through Pleistocene diatom datum levels that have been proven to be of stratigraphic utility in the North Pacific appear to be nearly isochronous within the level of resolution constrained by sample spacing. The assemblages are characterized by species typical of middle-to-high latitudes and regions of high surface-water productivity, predominantly by Coscinodiscus marginatus, Stephanopyxis species, Proboscia barboi, and Thalassiothrix longissima. Latest Miocene through Pliocene assemblages in the region of the California Current, however, are intermediate between those of subarctic and subtropical areas. As a result, neither the existing tropical nor the subarctic (high latitude) zonal schemes were applicable for this region. An interval of pronounced diatom dissolution detected throughout the Pliocene sequence apparently correspond to a relatively warmer paleoceanographic condition resulting in a slackening of the southward flow of the California Current.

El artículo se compone de una introducción que examina el pasaje evangélico de Mc 12, 13-17 en relación con el pago de los impuestos, como la fuente sustancial de la arcaica problemática religioso-política cristiana. El tema de religión y política de intrínseca complejidad incluye el estudio de un documento gnóstico directo, el Tratado Tripartito (NHC I, 5), porque él encierra el vocabulario filosófico político usado por los primeros cristianos. El estudio del testimonio investigado es, además, de utilidad, porque permite analizar con superior tecnicismo la concepción político-religiosa de Pablo de Tarso y sus posibles aplicaciones a la cultura política cristiana en formación. Teniendo en cuenta este contexto es posible ir más a fondo en la captación del sentido del kath’ ékhon que aparece en la epístola deutero-paulina a los tesalonicenses (2 Tes. 2, 1-12) y la relación de este conjunto de conceptos político-religiosos con las ideas paralelas, aunque ambivalentes, acuñadas por los autores de las generaciones inmediatas, es decir, los Padres Apostólicos. Las conclusiones abordan las consecuencias que se pueden extraer de estos planteamientos antiguos que se han mantenido en el Medioevo, y su posible efectividad para el mejoramiento de la concepción cristiana actual de la política.

Nearly complete Paleogene sedimentary sequences were recovered by Leg 114 to the subantarctic South Atlantic. Silicoflagellate assemblages from the Paleogene and immediately overlying lower Neogene from Sites 698 (Northeast Georgia Rise), 700 (East Georgia Basin), 702 (Islas Orcadas Rise), and 703 (Meteor Rise) were examined. The described assemblage from Hole 700B represents the most complete yet described from the Paleocene, encompassing planktonic foraminifer Zones Plb (upper part) through P4 and Subchrons C25N to C23N. All lower Eocene sediments are barren as a result of diagenesis, except for a single sample from Hole 698A. Middle Eocene silicoflagellates described from Hole 702B range in age from early middle Eocene (P10) to late Eocene (PI5), with correlations to Subchrons C21N to C18N. Hole 703A contains late Eocene through early Miocene assemblages, with paleomagnetic control from Subchrons C16R to C6AAN. Leg 114 biosiliceous sequences contain exceptionally diverse assemblages of silicoflagellates. Approximately 155 species and separate morphotypes are described from the Paleogene and earliest Neogene. New taxa described from Leg 114 sediments include Bachmannocena vetula n. sp., Corbisema animoparallela n. sp., Corbisema camara n. sp., Corbisema constricta spinosa n. subsp., Corbisema delicata n. sp., Corbisema hastata aha n. subsp., Corbisema praedelicata n. sp., Corbisema scapana n. sp., Corbisema triacantha lepidospinosa n. subsp., Dictyocha deflandreifurtivia n. subsp., Naviculopsis biapiculata nodulifera n. subsp., Naviculopsis cruciata n. sp., Naviculopsis pandalata n. sp., Naviculopsis primativa n. sp., and Naviculopsis trispinosa eminula n. subsp. Taxonomic revisions were made to the following taxa: Corbisema constricta constricta emended, Corbisema disymmetrica crenulata n. comb., Corbisema jerseyensis emended, and Distephanus antarcticus n. comb. Silicoflagellate assemblages from the Paleogene and earliest Neogene of Holes 698A, 699A, 700B, 702B, and 703A are the basis of a silicoflagellate zonation spanning the interval from 63.2 to 22.25 Ma. Silicoflagellate zones recognized in this interval include the Corbisema hastata hastata Zone, Corbisema hastata aha Zone, Dictyocha precarentis Zone, Naviculopsis constricta Zone, Naviculopsis foliacea Zone, Bachmannocena vetula Zone, Dictyocha grandis Zone, Naviculopsis pandalata Zone, Naviculopsis constricta-Bachmannocena paulschulzii Zone, Bachmannocena paulschulzii Zone, Naviculopsis trispinosa Zone with subzones a and b, Corbisema archangelskiana Zone, Naviculopsis biapiculata Zone, Distephanus raupii Zone, Distephanus raupii-Corbisema triacantha Zone, and Corbisema triacantha mediana Zone.

En "Estructura y dinámica del dominio de Santo Toribio de Liébana (siglos XIII-XVI)" se trata de explicar las características diferenciales que presenta un dominio monástico del área septentrional de la Península Ibérica. En la primera parte, siglo XIII y principios del siglo XIV, se considera que la pobreza material que ostenta el cenobio, observable en el escaso volumen de la renta y en las sucesivas enajenaciones de bienes efectuadas por sectores jerarquizados locales, es el resultado de la dispar consolidación de las estructuras feudales en el espacio. Frente a áreas cercanas al emplazamiento del monasterio en donde el señor limita la movilidad campesina y extrae excedentes elevados y estables, existen otras, consideradas como la "periferia" del dominio, en donde la pervivencia del ejercicio del derecho de retorno limitaba seriamente la consolidación de la propiedad dominical señorial. En dichas áreas, la estabilización de los derechos de propiedad del señor sólo se concretó a partir de la conformación de estructuras coercitivas de poder a nivel local que anularon el ejercicio efectivo del retorno familiar. En la segunda parte, siglos XIV-XVI, se analizan las estrategias específicas que permitieron el incremento del volumen de la renta en el largo plazo. Frente a las tesis que sostienen una temprana parcelación de la reserva y una conmutación de las prestaciones de trabajo, se observa aquí, por el contrario, el aumento de su extensión en los siglos finales de la Edad Media. Al mismo tiempo se detecta un proceso de parcelación de las tenencias campesinas, impulsado por el señor, que propiciaba un incremento de los fuegos sobre los que recaían las exacciones. Ambos aspectos, apropiación señorializada del espacio y aumento de la tasa de la renta, fueron el resultado del ejercicio efectivo de la coacción política.

A la hora de abordar empíricamente la problemática de la marginalidad en la baja edad media y temprana modernidad, período cuando este fenómeno se expandió en múltiples formas, la categorización resulta en una dificultad epistemológica para el análisis. Así, se hace necesaria la revisión de las diversas propuestas teóricas para poder delimitar el problema. Veremos específicamente la definición teórica de la marginalidad de aquellos hombres que fueron estigmatizados por ser pobres y, a pesar de ello, no integrarse a la comunidad mediante el trabajo. Elaboraremos un estado de la cuestión, para poder así realizar un balance con críticas y aportes referentes al problema epistemológico planteado
