Rammed earth walls in the late middle age castles in the actual province of Soria, Spain

This paper analyzed the building techniques based in the use of rammed earth in the Late Medieval fortifications in the province of Soria, Spain. The manorial castles of Serón de Nágima and Yanguas were built completely with rammed earth. However, these techinques are different. Through the study of the constructive signals, we can reconstruct the constructive process and made an hypothesis of the auxiliary scaffolding necessary for the construction. After, other four cases in which there is presence of rammed earth are described: Ágreda, Arcos de Jalón, Caracena and the tower of Martín González or castle of La Raya (the Border). Rammed earth is used in some secondary architectural elements and also as a filling of the masonry walls, but somtimes there are ancient rammed earth walls overlaid with stone masonry.

Primate postcrania from the late middle Eocene of Myanmar

Fossil primates have been known from the late middle to late Eocene Pondaung Formation of Myanmar since the description of Pondaungia cotteri in 1927. Three additional primate taxa, Amphipithecus mogaungensis, Bahinia pondaungensis and Myanmarpithecus yarshensis, were subsequently described. These primates are represented mostly by fragmentary dental and cranial remains. Here we describe the first primate postcrania from Myanmar, including a complete left humerus, a fragmentary right humerus, parts of left and right ulnae, and the distal half of a left calcaneum, all representing one individual. We assign this specimen to a large species of Pondaungia based on body size and the known geographic distribution and diversity of Myanmar primates. Body weight estimates of Pondaungia range from 4,000 to 9,000 g, based on humeral length, humeral midshaft diameter, and tooth area by using extant primate regressions. The humerus and ulna indicate that Pondaungia was capable of a wide variety of forelimb movements, with great mobility at the shoulder joint. Morphology of the distal calcaneus indicates that the hind feet were mobile at the transverse tarsal joint. Postcrania of Pondaungia present a mosaic of features, some shared in common with notharctine and adapine adapiforms, some shared with extant lorises and cebids, some shared with fossil anthropoids, and some unique. Overall, Pondaungia humeral and calcaneal morphology is most consistent with that of other known adapiforms. It does not support the inclusion of Pondaungia in Anthropoidea.

Diplacanthid acanthodians from the Aztec Siltstone (late Middle Devonian) of southern Victoria Land, Antartica

One articulated and several partial, semi-articulated specimens of acanthodians were collected in 1970 from the freshwater deposits of the Aztec Siltstone (Middle Devonian; Givetian), Portal Mountain, southern Victoria Land, Antarctica, during a Victoria University of Wellington Antarctic Expedition. The Portal Mountain fish fauna, preserved in a finely laminated, non-calcareous siltstone, includes acanthodians, palaeoniscoids, and bothriolepid placoderms. The articulated acanthodian specimens are the most complete fossil fish remains documented so far from the Aztec assemblage, which is the most diverse fossil vertebrate fauna known from Antarctica. They are described as a new taxon, Milesacanthus antarctica gen. et sp. nov., which is assigned to the family Diplacanthidae. Its fin spines show some similarities to spine fragments named Byssacanthoides debenhami from glacial moraine at Granite Harbour, Antarctica, and much larger spines named Antarctonchus glacialis from outcrops of the Aztec Siltstone in the Boomerang Range, southern Victoria Land. Both of these are reviewed, and retained as form taxa for isolated spines. Various isolated remains of fin spines and scales are described from Portal Mountain and Mount Crean (Lashly Range), and referred to Milesacanthus antarctica gen. et sp. nov. The histology of spines and scales is documented for the first time, and compared with acanthodian material from the Devonian of Australia and Europe. Distinctive fin spines from Mount Crean are provisionally assigned to Culmacanthus antarctica Young, 1989b. Several features on the most complete of the new fish specimens - in particular, the apparent lack of an enlarged cheek plate - suggest a revision of the diagnosis for the Diplacanthidae.

The subjunctive mood in Late Middle English adverbial clauses: the interaction of form and function

This thesis focuses on the history of the inflexional subjunctive and its functional substitutes in Late Middle English. To explore why and how the inflexional subjunctive declined in the history of English language, I analysed 2653 examples of three adverbial clauses introduced by if (1882 examples), though (305 examples) and lest (466 examples). Using a corpus-based approach, this thesis argues that linguistic change in subjunctive constructions did not happen suddenly but rather gradually, and the way it changed was varied , and that different constructions changed at different speeds in different environments. It is well known that the inflexional subjunctive declined in the history of English, mainly because of inflexional loss. Strangely however this topic has been comparatively neglected in the scholarly literature, especially with regard to the Middle English period, probably due to the limitations of data and also because study of this development requires very cumbersome textual research. This thesis has derived and analysed the data from three large corpora in the public domain: the Middle English Grammar Corpus (MEG-C for short), the Innsbruck Computer Archive of Machine-Readable English Texts (ICAMET for short), and some selected texts from The Corpus of Middle English Prose and Verse, part of the Middle English Compendium that also includes the Middle English Dictionary. The data were analysed from three perspectives: 1) clausal type, 2) dialect, and 3) textual genre. The basic methodology for the research was to analyse the examples one by one, with special attention being paid to the peculiarities of each text. In addition, this thesis draw on some complementary – indeed overlapping -- linguistic theories for further discussion: 1) Biber’s multi-dimensional theory, 2) Ogura and Wang’s (1994) S-curve or ‘diffusion’ theory, 3) Kretzchmar’s (2009) linguistics of speech, and 4) Halliday’s (1987) notion of language as a dynamic open system. To summarise the outcomes of this thesis: 1) On variation between clausal types, it was shown that the distributional tendencies of verb types (sub, ind, mod) are different between the three adverbial clauses under consideration. 2) On variation between dialects, it has been shown that the northern area, i.e. the so-called Great Scandinavian Belt, displays an especially high comparative ratio of the inflexional subjunctive construction compared to the other areas. This thesis suggests that this result was caused by the influence of Norse, relating the finding to the argument of Samuels (1989) that the present tense -es ending in the northern dialect was introduced by the influence of the Scandinavians. 3) On variation between genres, those labelled Science, Documents and Religion display relatively high ratio of the inflexional subjunctive, while Letter, Romance and History show relatively low ratio of the inflexional subjunctive. This results are explained by Biber’s multi-dimensional theory, which shows that the inflexional subjunctive can be related to the factors ‘informational’, ‘non-narrative’, ‘persuasive’ and ‘abstract’. 4) Lastly, on the inflexional subjunctive in Late Middle English, this thesis concludes that 1) the change did not happen suddenly but gradually, and 2) the way language changes varies. Thus the inflexional subjunctive did not disappear suddenly from England, and there was a time lag among the clausal types, dialects and genres, which can be related to Ogura and Wang’s S-curve (“diffusion”) theory and Kretzchmars’s view of “linguistic continuum”. This thesis has shown that the issues with regard to the inflexional subjunctive are quite complex, so that research in this area requires not only textual analysis but also theoretical analysis, considering both intra- and extra- linguistic factors.

Variabilité stylistique des occupations du Sylvicole moyen ancien (400 av. n.è. – 500 de n.è.) sur la station 3-arrière de Pointe-du-Buisson : approche typologique

Ce mémoire porte sur la variabilité observée dans un assemblage, composé à la fois d’artéfacts lithiques et céramiques, représentatif de la plus grande collection archéologique dominée par une composante du Sylvicole moyen ancien connue au Québec. Les traits caractéristiques des poteries qui ont été transportées, abandonnées, et en partie manufacturées sur la station 3-arrière du complexe de Pointe-du-Buisson, sont appréhendés à travers une acception holistique de la notion de «style», qui inclut tous les aspects des attributs qu’elle couvre, à savoir les technologiques, les morphologiques, les décoratifs et les fonctionnels. Grâce à l’application d’une méthode typologique, une approche peu utilisée depuis plusieurs décennies, du moins dans le Nord-Est américain, et dont le mérite propre réside dans sa capacité à traiter l’artéfact dans son ensemble, des schémas comportementaux (cognitifs et procéduraux) visibles sur les tessons de bord décorés ont été mis en lumière. Ces derniers sont intimement liés aux techniques décoratives employées par les potières, et semblent s’être modifiés au fil du temps de la manière suivante : type «sigillé» précédant les types plus récents «repoussé» et «basculant». Une analyse comparative, basée sur un échantillon de sites localisés dans la région de Haut-Saint-Laurent et dans celles avoisinantes, a par ailleurs souligné d’importantes similarités entre l’assemblage céramique de la composante du Sylvicole moyen ancien de BhFl-1d’ et ceux des sites de Vieux-Pont (Estrie), d’Oka (rivière des Outaouais), de Pointe-du-Gouvernement (Haut-Richelieu) et de Winooski (aux abords du Lac Champlain dans le Vermont). Ces résultats appuient l’identification d’une manifestation culturelle qui est très étroitement connectée aux phases Canoe Point et Winooski de la tradition Point Peninsula. Résultant des conclusions susmentionnées, et d’autres issues d’enquêtes récentes, des considérations d’ordre taxonomique s’ensuivent. Bien qu’une refonte complète du taxon «Sylvicole moyen» soit prématurée, une critique de ce taxon s’avère nécessaire. Aussi des taxons tels que l’Early Horticultural Period de Snow ou le «Sylvicole initial» de Wright et Clermont sont discutés, dans la mesure où ils pourraient renvoyer à une définition plus générale, mais aussi peut-être plus fidèle, des caractéristiques anthropologiques propres aux populations qui ont vécu le long du Saint-Laurent et de ses tributaires depuis le Sylvicole inférieur jusqu’à la fin du Sylvicole moyen tardif.

La néolithisation dans la région de Montréal depuis le Sylvicole moyen tardif : apport archéopalynologique

Des preuves archéopalynologiques directes appuient maintenant l’hypothèse d’une lente adaptation horticole durant la néolithisation amérindienne de la région de Montréal. Les sites archéologiques Hector-Trudel (BhFl-1a) de Pointe-du-Buisson et Séminaire de Saint-Sulpice (BjFj-18) dans le Vieux-Montréal ont été retenus pour élaborer une méthodologie archéopalynologique d’étude des sols archéologiques. Cela a permis de caractériser l’impact de la présence humaine sur l'environnement végétal des sites et d’identifier des indices de culture et de gestion de plantes allogènes et indigènes. Un complexe horticole de production à petite échelle de maïs (Zea mays), de tournesol (Helianthus annuus) et de petit tabac (Nicotiana rustica) et une forme de gestion des arbustes à petits fruits sont identifiés au site Hector-Trudel durant le Sylvicole moyen tardif (500 à 1000 A.D.). Ces cultigènes sont aussi identifiés au site du Séminaire pour la fin du Sylvicole supérieur ancien (1200 à 1300 A.D.), dans des proportions toutefois plus importantes, et une activité de gestion forestière au profit des arbres à noix et du tilleul d’Amérique (Tilia americana), reflet des pratiques d’entretien des champs cultivés, témoignent d’une évolution dans les comportements

Évolution et transmission des savoir-faire céramiques au cours du Sylvicole (-1000 à 1550 de notre ère) : la station 3-avant de Pointe-du-Buisson (BhFl-1d), Haut-Saint-Laurent, Québec.

La station 3-avant de Pointe-du-Buisson (Beauharnois, Haut-Saint-Laurent, Québec) représente la plus importante collection de récipients de terre cuite datant du Sylvicole moyen ancien (-400 à 500 de notre ère) dans le Nord-Est américain. De plus, on trouve sur ce site une série continue d’occupations couvrant l’ensemble de la période Sylvicole. En dépit de complications d’ordre stratigraphique (terreau homogène et pédoturbations), des concepts et des méthodes évolutionnaires tirés de la théorie de l’hérédité duelle sont appliqués à l’étude de cet assemblage. D’un point de vue anthropologique, que nous apprend l’étude de l’évolution et de la transmission des savoir-faire d’une technologie que nous assumons exclusivement féminine au cours de la période Sylvicole? L’auteur défend que l’archéologie évolutionnaire permet de détecter le contexte de la transmission, c’est-à-dire l’organisation socioéconomique des populations du passé. L’examen des traits stylistiques suggère que la sédentarisation estivale des bandes amérindiennes à partir du Sylvicole moyen tardif favorise une homogénéisation des productions céramiques dans un contexte virilocal qui est la conséquence d’une transmission de type conformiste opérant sur un axe horizontal (entre pairs). Cependant, le passage probable des tribus iroquoiennes à l’uxorilocalité et à la matrilinéarité à la fin du Sylvicole se traduit par une saisissante hétérogénéisation des pots, qui s’explique possiblement par une sélection de marqueurs identitaire d’ordre clanique (transmission verticale entre parents et descendants). L’étude des traits techno-fonctionnels indique une diversification de la vaisselle de terre cuite à mesure que les populations intensifient leurs expériences sur les cultigènes. Dans l’ensemble, cette évolution trahit une attention accrue conférée à la performance des pots en tant que récipients culinaires. Par ailleurs, le concours de la sériation et de datations AMS permet la reconnaisance d’un taxon « Sylvicole moyen moyen » caractérisé par une modification morphologique et décorative des vases. Une enquête comparative portant sur un échantillon de 27 sites archéologiques de l’horizon Pseudo-scallop-shell démontre que la variation populationnelle est structurée en fonction de la localisation des communautés dans un bassin hydrographique spécifique. Par conséquent, l’auteur soumet des pistes en vue de l’élaboration d’une taxonomie robuste et propre au Sylvicole moyen ancien et au Sylvicole moyen moyen. Enfin, des indices de natures diverses (archéologiques, paléoethnobotaniques, ethnolinguistiques, paléoanthropologiques, et d’autres issus de la génétique des populations) suggèrent une identité proto-algonquienne des bandes des deux sous-périodes susmentionnées.

Origin of cadmium enrichments in carbonate rocks deposited in the Alpine Tethys area during the Middle-Late Jurassic

ABSTRACTThe pollution of air, soil and water by heavy metals through anthropogenic activities is an object of numerous environmental studies since long times. A number of natural processes, such as volcanic activity, hydrothermal fluid circulation and weathering of metal-rich deposits may lead to an additional and potentially important input and accumulation of heavy metals in the environment. In the Swiss and French Jura Mountains, anomalous high cadmium (Cd) concentrations (up to 16 ppm) in certain soils are related to the presence of underlying Cd-enriched (up to 21 ppm) carbonate rocks of Middle to Late Jurassic age. The aim of this study is to understand the processes controlling Cd incorporation into carbonate rocks of Middle and Late Jurassic age and to reconstruct the sedimentary and environmental conditions, which have led to Cd enrichments in these sedimentary rocks.Cd concentrations in studied hemipelagic sections in France vary between 0.1 and 0.5 ppm (mean 0.15 ppm). Trace-element behavior and high Mn concentrations suggest that sediment accumulation occurred in a well-oxygenated environment. Increases in Cd contents in the bulk-rock carbonate sediments may be related to increases in surface-water productivity under oxic conditions and important remineralization of organic matter within the water column. In platform settings preserved in the Swiss Jura Mountains, no correlation is observed between Cd contents and evolution of environmental conditions. Cd concentrations in these platform sections are often below the detection limit, with isolated peaks of up to 21 ppm. These important Cd enrichments are associated with peaks in Zn concentrations and are present in carbonate rocks independently of facies and age. The high Cd contents in these shallow-water carbonate rocks are partly related to the presence of disseminated, Cd-rich (up to 1.8%), sphalerite (ZnS) mineralization. The basement rocks are considered to be the source of metals for sulfide mineralization in the overlying Jurassic strata, as the sphalerite Pb isotope pattern is comparable to that of granite rocks from the nearby southern Black Forest crystalline massif. The Rb-Sr ages of sphalerite samples indicate that a main phase of sphalerite formation occurred near the boundary between the late Middle and early Late Jurassic, at around 162 Ma, as a result of enhanced tectonic and hydrothermal activity in Europe, related to the opening of the Central Atlantic and to the tectonic/thermal subsidence during spreading of the Alpine Tethys. I therefore propose to use unusually high Cd concentrations in carbonates as a tracer of tectonic activity in the Jura Mountains area, especially in the case when important enrichments in Zn co-occur. Paleoproductivity reconstructions based on records of authigenic Cd may be compromised not only by post-depositional redistribution, but also by incorporation of additional Cd from hydrothermal solutions circulating in the rock.The circulation of metal-rich hydrothermal fluids through the sediment sequence, in addition to specific environmental conditions during sedimentation, contributes to the incorporation of Cd into the carbonate rocks. However, only hydrothermal activity has led to the unusually high concentrations of Cd in carbonate rocks of Bajocian-Oxfordian age, through the formation of sphalerite mineralization.

Middle Eocene to late Oligocene calcareous nannofossils of ODP Hole 120-748B

A major deterioration in global climate occurred through the Eocene-Oligocene time interval, characterized by long-term cooling in both terrestrial and marine environments. During this long-term cooling trend, however, recent studies have documented several short-lived warming and cooling phases. In order to further investigate high-latitude climate during these events, we developed a high-resolution calcareous nannofossil record from ODP Site 748 Hole B for the interval spanning the late middle Eocene to the late Oligocene (~42 to 26 Ma). The primary goals of this study were to construct a detailed biostratigraphic record and to use nannofossil assemblage variations to interpret short-term changes in surface-water temperature and nutrient conditions. The principal nannofossil assemblage variations are identified using a temperate-warm-water taxa index (Twwt), from which three warming and five cooling events are identified within the middle Eocene to the earliest Oligocene interval. Among these climatic trends, the cooling event at ~39 Ma (Cooling Event B) is recorded here for the first time. Variations in fine-fraction d18O values at Site 748 are associated with changes in the Twwt index, supporting the idea that significant short-term variability in surface-water conditions occurred in the Kerguelen Plateau area during the middle and late Eocene. Furthermore, ODP Site 748 calcareous nannofossil paleoecology confirms the utility of these microfossils for biostratigraphic, paleoclimatic, and paleoceanographic reconstructions at Southern Ocean sites during the Paleogene.

Loneliness in Middle and Old Age

Purpose of the research: (a) To identify the degree of much loneliness reported in the Portuguese population over 50 years of age and (b) test whether loneliness can be predicted by socio-demographic, health related or social characteristic of the sample other than age. Materials and methods: 1174 late middle age and older adults were interviewed face to face by different interviewers across the country; after the informed consent was signed, we asked the participants several socio-demographic and health-related questions; finally we asked ‘‘How often do you feel lonely?’’ and participants responded according to a five point Likert scale. Principal results: The results showed that 12% of participants reporting feeling lonely often or always, whereas 40% reporting never feeling lonely. The remaining 48% self-reported they felt lonely seldom or sometimes. Additionally, results show that, when taken together, variables such as marital status, type of housing, residence settings, health conditions, social satisfaction, social isolation, lack of interest, transportation, and age were predictors of loneliness. Major conclusions: (1) The association of loneliness with advanced age has been greatly exaggerated by mass media and common sense; (2) But although our findings did not confirm the most alarmist views, the 12% of older adults reporting that they are feeling lonely always or often should be cause for attention and concern. It is necessary to understand the meaning, reasons and level of suffering implied on those feelings of loneliness. (3) Our findings suggest that it makes no sense to construe age as a singular feature or cause for feelings of loneliness. Instead, age and also a number of other features combine to predict feelings of loneliness. But even with our predictor variables there was a substantial of variance left unexplained. Therefore it is necessary to continue exploring how feelings of loneliness arise from the experience of living and how they can be changed.

New Early to Middle Triassic U-Pb ages from South China: Calibration with ammonoid biochronozones and implications for the timing of the Triassic biotic recovery

New zircon U-Pb ages are proposed for late Early and Middle Triassic volcanic ash layers from the Luolou and Baifeng formations (northwestern Guangxi, South China). These ages are based on analyses of single, thermally annealed and chemically abraded zircons. Calibration with ammonoid ages indicate a 250.6 +/- 0.5 Ma age for the early Spathian Tirolites/Columbites beds, a 248.1 +/- 0.4 Ma age for the late Spathian Neopopanoceras haugi Zone, a 246.9 +/- 0.4 Ma age for the early middle Anisian Acrochordiceras hyatti Zone, and a 244.6 +/- 0.5 Ma age for the late middle Anisian Balatonites shoshonensis Zone. The new dates and previously published U-Pb ages indicate a duration of ca. 3 my for the Spathian, and minimal durations of 4.5 +/- 0.6 my for the Early Triassic and of 6.6+0.7/-0.9 my for the Anisian. The new Spathian dates are in a better agreement with a 252.6 +/- 0.2 Ma age than with a 251.4 +/- 0.3 Ma age for the Permian-Triassic boundary. These dates also highlight the extremely uneven duration of the four Early Triassic substages (Griesbachian, Dienerian, Smithian, and Spathian), of which the Spathian exceeds half of the duration of the entire Early Triassic. The simplistic assumption of equal duration of the four Early Triassic subdivisions is no longer tenable for the reconstruction of recovery patterns following the end Permian mass extinction.

Evolution of the Pelagonian carbonate platform complex and the adjacent oceanic realm in response to plate tectonic forcing (Late Triassic and Jurassic), Evvoia, Greece

The Late Triassic and Jurassic platform and the oceanic complexes in Evvoia, Greece, share a complementary plate-tectonic evolution. Shallow marine carbonate deposition responded to changing rates of subsidence and uplift, whilst the adjacent ocean underwent spreading, and then convergence, collision and finally obduction over the platform complex. Late Triassic ocean spreading correlated with platform subsidence and the formation of a long-persisting peritidal passive-margin platform. Incipient drowning occurred from the Sinemurian to the late Middle Jurassic. This subsidence correlated with intra-oceanic subduction and plate convergence that led to supra-subduction calc-alkaline magmatism and the formation of a primitive volcanic arc. During the Middle Jurassic, plate collision caused arc uplift above the carbonate compensation depth (CCD) in the oceanic realm, and related thrust-faulting, on the platform, led to sub-aerial exposures. Patch-reefs developed there during the Late Oxfordian to Kimmeridgian. Advanced oceanic nappe-loading caused platform drowning below the CCD during the Tithonian, which is documented by intercalations of reefal turbidites with non-carbonate radiolarites. Radiolarites and bypass-turbidites, consisting of siliciclastic greywacke, terminate the platform succession beneath the emplaced oceanic nappe during late Tithonian to Valanginian time.
