Potential Shifts in Canadian High Arctic Sedimentary Organic Matter Composition With Permafrost Active Layer Detachments

Increased temperature and precipitation in Arctic regions have led to deeper thawing and structural instability in permafrost soil. The resulting localized disturbances, referred to as active layer detachments (ALDs), may transport organic matter (OM) to more biogeochemically active zones. To examine this further, solid state cross polarization magic angle spinning 13C nuclear magnetic resonance (CPMAS NMR) and biomarker analysis were used to evaluate potential shifts in riverine sediment OM composition due to nearby ALDs within the Cape Bounty Arctic Watershed Observatory, Nunavut, Canada. In sedimentary OM near ALDs, NMR analysis revealed signals indicative of unaltered plant-derived material, likely derived from permafrost. Long chain acyclic aliphatic lipids, steroids, cutin, suberin and lignin occurred in the sediments, consistent with a dominance of plant-derived compounds, some of which may have originated from permafrost-derived OM released by ALDs. OM degradation proxies for sediments near ALDs revealed less alteration in acyclic aliphatic lipids, while constituents such as steroids, cutin, suberin and lignin were found at a relatively advanced stage of degradation. Phospholipid fatty acid analysis indicated that microbial activity was higher near ALDs than downstream but microbial substrate limitation was prevalent within disturbed regions. Our study suggests that, as these systems recover from disturbance, ALDs likely provide permafrost-derived OM to sedimentary environments. This source of OM, which is enriched in labile OM, may alter biogeochemical patterns and enhance microbial respiration within these ecosystems.

Language Teaching Methodologies, Intercultural Awareness and Autonomous Learning

This paper will examine familiar reasons for including the teaching of intercultural competence within Language Teaching before adding some less familiar ones. It will focus in particular on the question of how far intercultural competence can be learned when students are formally studying languages and how far such competence needs to be acquired autono-mously. It will though also ask to what extent being initiated to the very varied facets of in-tercultural competence during formal language study plays an important role in allowing ef-fective autonomous acquisition to take place. The paper will conclude that a significant part of the intercultural development that students need to undertake if they are to be able to communicate effectively in a foreign language must happen autonomously, but that it is, nonetheless, vital that language courses at least sow the seeds of intercultural learning in ways that will facilitate autonomous learning. As such, language courses, if they are genuinely to meet student needs, should incorporate elements of intercultural training. The paper also concludes by outlining the type of empirical research that would need to be carried out for these claims to be fully substantiated.

"Lancea", Lusitanian Word, and the "Lancienses" Ethnogenesis

Analysis of the word lancea, of Hispanic origin after Varro, and of place names, people´s names and personal names derived from it. It confirms that the spear was the most important weapon in the Bronze Age, belonging to the iuventus and used as heroic and divine symbol. This analysis confirms also the personality of the Lusitanians, a people related to the Celts but with more archaic archaeological, linguistic and cultural characteristics originated in the tradition of the Atlantic Bronze in the II millennium BC. It is also relevant to better know the organisation of Broze and Iron Age societies and the origin of Indo-Europeans peoples in Western Europe and of pre-Roman peoples of Iberia.

Adesp. fr. 700 K.-Sn. y "Andrómeda" de Eurípides

adesp. fr. 700 Kn.-Sn. podría proceder de Andrómeda de Eurípides y no de una Níobe. Los siguientes elementos de los frs. (a) y (b) pueden responder a lo que se conoce de la tragedia de Eurípides: (a) la semejanza con una estatua; (b) la novia de Hades; (c) el silencio del personaje; (d) la colaboración con las Moiras; (e) el contraste entre la fortuna regia y la desgracia y el sufrimiento de los padres. No es, por tanto, necesario modificar el texto recibido para eliminar μάγους πάγας y la referencia a las trampas mágicas en el v. 5, que cuadra bien con Medusa y Perseo.

The magical transformation contest in the ancient storytelling tradition

El concurso de transformación mágica, esquema narrativo difundido en la tradición popular, se presenta en dos variantes principales: los hechiceros que compiten pueden metamorfosearse en varios seres o crear esos seres por medios mágicos. En cualquier caso el concursante ganador da a luz criaturas más fuertes que superan las de su oponente. La segunda variante fue preferida en el antiguo Cercano Oriente (Sumeria, Egipto, Israel). La primera se puede encontrar en algunos mitos griegos sobre cambiadores de forma (por ejemplo, Zeus y Némesis). El mismo esquema narrativo puede haber influido en un episodio de la Novela de Alejandro (1.36-38), en el que Darío envía regalos simbólicos a Alejandro y los dos monarcas enemigos ofrecen contrastantes explicaciones de ellos. Esta historia griega racionaliza el concurso de cuento de hadas, transfiriendo las fantásticas hazañas de creaciones milagrosas a un plano secundario pero realista de metáfora lingüística.

La exploración del litoral atlántico norteafricano según el periplo de Hannón de Cartago

El periplo de Hannón, frente a las propuestas que lo interpretan como una obra literaria, creemos que recoge un periplo auténtico, que sólo alcanzó cabo Juby y algunas de las Islas Canarias. Las refundaciones cartaginesas fueron todas en la Mauretania fértil, en los 7 primeros días de la expedición. Desde el islote de Kérne, en la expedición primó una primera exploración de evaluación, indicativo de que se trataba de apenas 2 o 3 barcos, con una tripulación limitada, que evitaban enfrentamientos con la población local. Los intérpretes Lixítai parecen conocer todos los puntos explorados, el río Chrétes, los etíopes del Alto Atlas costero, el gran golfo caluroso que finalizaba en el Hespérou Kéras, el volcán Theôn Óchema, o las gentes salvajes que denominaban Goríllai. Probablemente la mayor sorpresa fuese encontrar un volcán activo, emitiendo lava, que pudo ser la razón última para redactar este periplo. La falta de agua, alimentos y caza como razón para finalizar la expedición exploratoria sólo es comprensible en un trayecto corto que alcanzó hasta el inicio del desierto del Sahara. Otro tanto sucede con la ausencia de ríos importantes al Sur del río Chrétes, una clara prueba de que no se alcanzaron latitudes ecuatoriales y que los barcos se fueron alejando de la costa norteafricana.

Tifones y gigantes en el mundo macedonio: el rey como símbolo del orden cósmico

Este artículo analiza la existencia de un posible ritual en la antigua Macedonia que fuese similar al Akîtu babilonio. Pensamos que la victoria de Zeus sobre sus enemigos en la gigantomaquia y tifonomaquia fue celebrada por los reyes macedonios para fortalecer su posición en el poder. Aunque no hay evidencias directas de ello, tenemos una serie de diferentes fuentes en las cuales los macedonios están relacionados directa o indirectamente con Tifón y los gigantes. Además, la estratégica importancia del monte Olimpo para los macedonios nos hace pensar que la victoria de Zeus sobre las fuerzas del mal fue conmemorada de alguna forma por ellos.

Antiguas comunidades judías en Macedonia, Tracia y Épiro Superior

Evidencias de carácter literario, epigráfico y arqueológico-arquitectónicas, atestiguan la existencia de comunidades judías en Macedonia, Tracia y Épiro Superior (hoy Albania) durante los períodos romano y bizantino temprano. Los Hechos de los Apostoles mencionan la presencia de comunidades judías, y sus sinagogas, en Filipos, Tesalónica y Verroia, en Macedonia. El descubrimiento de inscripciones griegas en Bizya (Tracia), en Tesalónica y Dión, y en la antigua sinagoga de Stobia, sugieren que dichas comunidades preservaron su independencia religiosa y gozaron de un seguro estatus social, económico y cultural. Una antigua tumba judía encontrada en Tesalónica, decorada con una menorah, la sinagoga de Claudius Tiberius Polycharmos en Stobia y la de Saranda (Épiro Superior), añaden pruebas arqueológico- arquitectónicas a las fuentes literarias. A pesar de que las fuentes literarias, los datos epigráficos y los hallazgos arqueológicos son relativamente escasos, parece que en estas regiones, y en otras de la Península Balcánica, existieron también otras comunidades judías.

El ritual en los "Textos de las Pirámides": sintaxis, texto y significado

Este trabajo pretende explorar la dimensión ritual en los Textos de las Pirámides, el corpus de literatura religiosa extensa más antiguo de la humanidad. La naturaleza variada de sus componentes textuales ha impedido que los egiptólogos comprendan en profundidad las complejidades de la colección y los contextos originales en los que estos textos (ritos) aparecieron. La aplicación de la teoría del ritual, principalmente la aproximación de la sintaxis ritual, ofrece a los investigadores un marco excelente de análisis e interpretación del corpus, su estructura y función. Sujeto a las reglas de la sintaxis ritual es posible exponer los múltiples niveles de significado en el corpus para la resurrección y salvación del difunto.

Technical metaphor in Spanish-English translation of the fields of blindness, fatigue, and the spiritual world

The correspondence in the Spanish-English translation is analyzed of three different fields of technical metaphors based upon blindness, fatigue, and the spiritual world. Some terms have been left aside that under the appearance of metaphors were mere samples of no-deviated language or cases of homonymy. The study reveals a higher presence of the metaphor in the Spanish language in the three fields of study, although the English language also shows a high index of metaphors. In between metaphors and non-metaphors, we find a lack of metaphorical equilibrium between Spanish and English in certain cases, which is a sign of the different perception of the reality. Finally, the conclusions shed light on the meaning of these words: blind, annoyance, fatigue, antifading, core, angels, espectrum, phantom, ghost, magic, postmortem, dead, etc.

Biomarker analysis in oesophagogastric cancer: Results from the REAL3 and TransMAGIC trials.

BACKGROUND: REAL3 (Randomised ECF for Advanced or Locally advanced oesophagogastric cancer 3) was a phase II/III trial designed to evaluate the addition of panitumumab (P) to epirubicin, oxaliplatin and capecitabine (EOC) in untreated advanced oesophagogastric adenocarcinoma, or undifferentiated carcinoma. MAGIC (MRC Adjuvant Gastric Infusional Chemotherapy) was a phase III study which demonstrated that peri-operative epirubicin, cisplatin and infused 5-fluorouracil (ECF) improved survival in early oesophagogastric adenocarcinoma. PATIENTS AND METHODS: Analysis of response rate (RR; the primary end-point of phase II) and biomarkers in the first 200 patients randomised to EOC or modified dose (m) EOC+P in REAL3 was pre-planned to determine if molecular selection for the on-going study was indicated. KRAS, BRAF and PIK3CA mutations and PTEN expression were assessed in pre-treatment biopsies and results correlated with response to mEOC+P. Association between these biomarkers and overall survival (OS) was assessed in MAGIC patients to determine any prognostic effect. RESULTS: RR was 52% to mEOC+P, 48% to EOC. Results from 175 assessable biopsies: mutations in KRAS (5.7%), BRAF (0%), PIK3CA (2.5%) and loss of PTEN expression (15.0%). None of the biomarkers evaluated predicted resistance to mEOC+P. In MAGIC, mutations in KRAS, BRAF and PIK3CA and loss of PTEN (phosphatase and tensin homolog) were found in 6.3%, 1.0%, 5.0% and 10.9%, respectively, and were not associated with survival. CONCLUSIONS: The RR of 52% in REAL3 with mEOC+P met pre-defined criteria to continue accrual to phase III. The frequency of the mutations was too low to exclude any prognostic or predictive effect.

Vänskap är magisk : En reparativ läsning av samtida svensk seriekonst

In this thesis, I do a reparative reading of contemporary Swedish comics, that uses feminine signifiers, both in their imagery and writing. A crucial point of departure, in this thesis, is how literature can ”do” theory and be seen as a way of creating knowledge. I explore what the comics does to me, as a reader, and how. I experiment with the form and style of academic writing in order to clearly define my position and situate the production of knowledge. By focusing on the affects and nourishment, that the comics contain, I try to imagine a feminist other, with the help of my figuration: Nietzsche Minaj, and my imaginary utopian place: ”mitt flick(tionella) rum”. I conclude, that the comics both reproduce and transform feminine signifiers, while challenging the idea of dichotomies, in the spirit of gurlesque theory.

Le polar de la Caraïbe francophone : enjeux de l’appropriation du genre

Pour minoré et ignoré qu’il fût, le roman policier est désormais légitimé par l’institution littéraire. À parcourir les livres publiés dans la Caraïbe francophone, le genre demeure dans la marge de cette production [issue de la Caraïbe francophone (Haïti, Guadeloupe, Guyane française, Martinique)]. Quoiqu’il en soit, on notera que les années 1990 ont inauguré une véritable éclosion de publications de polars. Tout cela augure d’une acclimatation de ce genre qui ne s’accompagne pas moins de questionnements sur les spécificités éventuelles du polar caribéen francophone. Se situe-t-il dans la convention? Tente-il au contraire d’établir une distanciation avec la norme? C’est pour répondre à ces interrogations que cette thèse se propose d’explorer les enjeux de l’appropriation du polar provenant de cette aire géographique. À l’aune de la poétique des genres, de la sociocritique et de l’intermédialité, un corpus composé de quatorze romans fait l’objet d’une étude approfondie. Dans le premier chapitre, un bref récapitulatif permet de situer les œuvres à l’étude dans l’histoire littéraire du genre tout en soulignant l’adaptation du polar dans la Caraïbe de langue française. Il en ressort qu’un nombre significatif d’écrivains, attentifs à la latence du magico-religieux dans leur société, mettent en scène le surnaturel alors que le roman policier conventionnel plébiscite la méthode logico-déductive. C’est la raison pour laquelle le second chapitre s’intéresse à l’usage de l’inexplicable et son rapport avec le cartésianisme. Quant au troisième chapitre, il se penche sur un topos du genre : la violence telle qu’elle surgit dans ses dimensions commémoratives et répétitives de l’histoire tumultueuse de la Caraïbe. Notre corpus tend à relier la notion du crime, fut-il d’emprise originelle, à l’histoire post-coloniale. Dans la mesure où les personnages constituent un élément clé du genre, ils sont sondés, dans un quatrième chapitre, en regard de la critique sociale qu’ils incarnent et véhiculent. Le dernier chapitre cherche à circonscrire l’intermédialité qui structure et qualifie l’œuvre au sein du roman policier depuis sa genèse. Somme toute, ces divers axes contribuent à mieux comprendre le phénomène de transposition du polar dans cette région du monde.

Principles and Practice of Fire Modelling: A Collection of Lecture Notes for a Short Course

Once the preserve of university academics and research laboratories with high-powered and expensive computers, the power of sophisticated mathematical fire models has now arrived on the desk top of the fire safety engineer. It is a revolution made possible by parallel advances in PC technology and fire modelling software. But while the tools have proliferated, there has not been a corresponding transfer of knowledge and understanding of the discipline from expert to general user. It is a serious shortfall of which the lack of suitable engineering courses dealing with the subject is symptomatic, if not the cause. The computational vehicles to run the models and an understanding of fire dynamics are not enough to exploit these sophisticated tools. Too often, they become 'black boxes' producing magic answers in exciting three-dimensional colour graphics and client-satisfying 'virtual reality' imagery. As well as a fundamental understanding of the physics and chemistry of fire, the fire safety engineer must have at least a rudimentary understanding of the theoretical basis supporting fire models to appreciate their limitations and capabilities. The five day short course, "Principles and Practice of Fire Modelling" run by the University of Greenwich attempt to bridge the divide between the expert and the general user, providing them with the expertise they need to understand the results of mathematical fire modelling. The course and associated text book, "Mathematical Modelling of Fire Phenomena" are aimed at students and professionals with a wide and varied background, they offer a friendly guide through the unfamiliar terrain of mathematical modelling. These concepts and techniques are introduced and demonstrated in seminars. Those attending also gain experience in using the methods during "hands-on" tutorial and workshop sessions. On completion of this short course, those participating should: - be familiar with the concept of zone and field modelling; - be familiar with zone and field model assumptions; - have an understanding of the capabilities and limitations of modelling software packages for zone and field modelling; - be able to select and use the most appropriate mathematical software and demonstrate their use in compartment fire applications; and - be able to interpret model predictions. The result is that the fire safety engineer is empowered to realise the full value of mathematical models to help in the prediction of fire development, and to determine the consequences of fire under a variety of conditions. This in turn enables him or her to design and implement safety measures which can potentially control, or at the very least reduce the impact of fire.
