Quantitative and Qualitative Aspects of Dissolved Organic Carbon Leached from Senescent Plants in an Oligotrophic Wetland

We conducted a series of experiments whereby dissolved organic matter (DOM) was leached from various wetland and estuarine plants, namely sawgrass (Cladium jamaicense), spikerush (Eleocharis cellulosa), red mangrove (Rhizophora mangle), cattail (Typha domingensis), periphyton (dry and wet mat), and a seagrass (turtle grass; Thalassia testudinum). All are abundant in the Florida Coastal Everglades (FCE) except for cattail, but this species has a potential to proliferate in this environment. Senescent plant samples were immersed into ultrapure water with and without addition of 0.1% NaN3 (w/ and w/o NaN3, respectively) for 36 days. We replaced the water every 3 days. The amount of dissolved organic carbon (DOC), sugars, and phenols in the leachates were analyzed. The contribution of plant leachates to the ultrafiltered high molecular weight fraction of DOM (>1 kDa; UDOM) in natural waters in the FCE was also investigated. UDOM in plant leachates was obtained by tangential flow ultrafiltration and its carbon and phenolic compound compositions were analyzed using solid state 13C cross-polarization magic angle spinning nuclear magnetic resonance (13C CPMAS NMR) spectroscopy and thermochemolysis in the presence of tetramethylammonium hydroxide (TMAH thermochemolysis), respectively. The maximum yield of DOC leached from plants over the 36-day incubations ranged from 13.0 to 55.2 g C kg−1 dry weight. This amount was lower in w/o NaN3 treatments (more DOC was consumed by microbes than produced) except for periphyton. During the first 2 weeks of the 5 week incubation period, 60–85% of the total amount of DOC was leached, and exponential decay models fit the leaching rates except for periphyton w/o NaN3. Leached DOC (w/ NaN3) contained different concentrations of sugars and phenols depending on the plant types (1.09–7.22 and 0.38–12.4 g C kg−1 dry weight, respectively), and those biomolecules comprised 8–34% and 4–28% of the total DOC, respectively. This result shows that polyphenols that readily leach from senescent plants can be an important source of chromophoric DOM (CDOM) in wetland environments. The O-alkyl C was found to be the major C form (55±9%) of UDOM in plant leachates as determined by 13C CPMAS NMR. The relative abundance of alkyl C and carbonyl C was consistently lower in plant-leached UDOM than that in natural water UDOM in the FCE, which suggests that these constituents increase in relative abundance during diagenetic processing. TMAH thermochemolysis analysis revealed that the phenolic composition was different among the UDOM leached from different plants, and was expected to serve as a source indicator of UDOM in natural water. Polyphenols are, however, very reactive and photosensitive in aquatic environments, and thus may loose their plant-specific molecular characteristics shortly. Our study suggests that variations in vegetative cover across a wetland landscape will affect the quantity and quality of DOM leached into the water, and such differences in DOM characteristics may affect other biogeochemical processes.

The Enchanter's Spell: J.R.R. Tolkien's Mythopoetic Response to Modernism

J.R.R. Tolkien was not only an author of fantasy but also a philologist who theorized about myth. Theorists have employed various methods of analyzing myth, and this thesis integrates several analyses, including Tolkien’s. I address the roles of doctrine, ritual, cross-cultural patterns, mythic expressions in literature, the literary effect of myth, evolution of language and consciousness, and individual invention over inheritance and diffusion. Beyond Tolkien’s English and Catholic background, I argue for eclectic influence on Tolkien, including resonance with Buddhism. Tolkien views mythopoeia, literary mythmaking, in terms of sub-creation, human invention in the image of God as creator. Key mythopoetic tools include eucatastrophe, the happy ending’s sudden turn to poignant joy, and enchantment, the realization of imagined wonder, which is epitomized by the character of Tom Bombadil and contrasted with modernist techno-magic seeking to alter and dominate the world. I conclude by interpreting Tolkien’s mythmaking as a form of mysticism.

The Saints of Banias

THE SAINTS OF BANIAS is a novel set in a fictional slavetown during the Reconstruction Era. The work seeks to blend myth, magic, and history to create a world that is both believable and otherworldly. The novel follows Beah, an ex-slave girl travelling to the town of Banias in hopes of finding her mother; Prophet Moon, an itinerant vision-seer who offers to help Beah with her goal; and the founder of the town, Claude Banias, who struggles to protect Banias from bloodthirsty radicals. As the characters’ lives intertwine, they face more challenges and secrets. THE SAINTS OF BANIAS is loosely based on the biblical story of David and Bathsheba, with Claude acting as David, Beah as Bathsheba, and Prophet Moon as a hybrid of Nathan and Uriah. The novel primarily explores destructive love, the value of hope, and the price of preserving a culture.

Fatores capazes de influenciar o encantamento do cliente de turismo de lazer a partir da experiência em parques temáticos

Com o aumento da demanda por empreendimentos no ramo do entretenimento, observa-se o aumento da competitividade no setor de turismo, gerando a necessidade de diferenciação em meio aos demais, visando à fidelização de clientes. Nesse sentido, os profissionais de Marketing passaram a acreditar que, para oferecer algo que fosse capaz de fidelizar os clientes, as empresas deveriam oferecer um produto ou serviço que fosse além das necessidades dos consumidores, surgindo então o termo “encantamento do cliente”. Nesse contexto, o presente estudo tem o objetivo de analisar fatores considerados como capazes de influenciar o encantamento do cliente (Customer Delight) de turismo de lazer, a partir de experiências em parques temáticos, por meio de uma abordagem baseada na Teoria da Avaliação Cognitiva. Para tanto, a investigação apresentou caráter exploratório-descritivo com enfoque analítico-quantitativo. A pesquisa foi do tipo Levantamento (Survey). Os dados foram coletados a partir de um público composto por 176 adolescentes que viajaram em excursão para o Walt Disney World, localizado em Orlando, Flórida, em junho de 2014, por uma agência de viagem localizada na cidade de Natal/ RN. O parque escolhido para objeto da pesquisa foi o Magic Kingdom. Para análise das respostas, foram utilizadas as análises descritiva, fatorial exploratória e confirmatória, assim como a modelagem de equações estruturais. Os resultados apontam para um grande nível de encantamento do entrevistado com o objeto, seja relacionado com a importância do objetivo da viagem, assim como à dimensão Inesperado da viagem. Pelas relações causais encontradas, observou-se que as dimensões “Coerência do Objetivo” e “Importância do Objetivo”, ambas consideradas como antecedentes do Encantamento, têm impactos significativos na formação do Encantamento do Cliente. As constatações permitiram ampliar a compreensão sobre o comportamento do consumidor no turismo de lazer.

ESPÍRITOS DO UNIVERSO RESPONSÁVEIS PELO DESTINO: ESTUDO EXEGÉTICO EM COLOSSENSES 2.8-3.4

Esta dissertação de mestrado analisará a expressão grega ta. stoicei/a tou/ ko,smou, “os elementos do mundo”, que ocorre na carta de Colossenses nos versículos 8 e 20 do segundo capítulo. Será feito um estudo exegético na perícope bíblica 2.8-3.4 da referida carta, bem como uma análise histórica especificamente do termo stoicei/a. O estudo desta expressão é importante para poder se compreender a filosofia colossense mencionada em Cl 2.8. A igreja cristã na cidade de Colossos estava inserida em um contexto social religioso sincrético. Esse sincretismo é percebido claramente em textos de magia como os Papiros Mágicos Gregos, muito comuns na região da Ásia Menor, a mesma onde a igreja colossense estava situada. O sincretismo religioso, envolvendo crenças judaicas e pagãs, reflete as bases dessa filosofia. O autor da carta aos Colossenses refuta a crença nos “elementos do mundo”, bem como a subserviência aos mesmos. Dentre outras crenças, acreditava-se que esses “elementos” poderiam influenciar os acontecimentos sobre a terra e o destino das pessoas. Questões que envolvem práticas acéticas, adoração a anjos e observância de calendário litúrgico, dão os contornos dessa filosofia. O autor da carta enfatiza o senhorio de Cristo, bem como as obras dele em favor dos cristãos colossenses, que proporcionavam a eles, segurança quanto a terem um bom destino. E, além disso, é assegurada uma liberdade aos cristãos colossenses que não podia lhes ser cerceada por quaisquer outras crenças religiosas. Então, as obras de Cristo, bem como o seu senhorio, são os principais argumentos utilizados pelo autor da carta, a fim de afirmar aos cristãos em Colossos que eles não precisam mais temer o destino e nem se submeter aos “elementos do mundo”.

Using knowledge management to give context to analytics and big data and reduce strategic risk

At the moment, the phrases “big data” and “analytics” are often being used as if they were magic incantations that will solve all an organization’s problems at a stroke. The reality is that data on its own, even with the application of analytics, will not solve any problems. The resources that analytics and big data can consume represent a significant strategic risk if applied ineffectively. Any analysis of data needs to be guided, and to lead to action. So while analytics may lead to knowledge and intelligence (in the military sense of that term), it also needs the input of knowledge and intelligence (in the human sense of that term). And somebody then has to do something new or different as a result of the new insights, or it won’t have been done to any purpose. Using an analytics example concerning accounts payable in the public sector in Canada, this paper reviews thinking from the domains of analytics, risk management and knowledge management, to show some of the pitfalls, and to present a holistic picture of how knowledge management might help tackle the challenges of big data and analytics.

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.

Fleshing Out and Losing Flesh: The Decomposing Corpse as Narrative Object in American Hardboiled Detective Fiction

This dissertation examines the corpse as an object in and of American hardboiled detective fiction written between 1920 and 1950. I deploy several theoretical frames, including narratology, body-as-text theory, object relations theory, and genre theory, in order to demonstrate the significance of objects, symbols, and things primarily in the clever and crafty work of Dashiell Hammett (1894-1961) and Raymond Chandler (1888-1959), but also touching on the writings of their lesser known accomplices. I construct a literary genealogy of American hardboiled detective fiction originating in the writings of Edgar Allan Poe, compare the contributions of classic or Golden Age detective fiction in England, and describe the socio-economic contexts, particularly the predominance of the “pulps,” that gave birth to the realism of the Hardboiled School. Taking seriously Chandler’s obsession with the art of murder, I engage with how authors pre-empt their readers’ knowledge of the tricks of the trade and manipulate their expectations, as well as discuss the characteristics and effect of the inimitable hardboiled style, its sharpshooting language and deadpan humour. Critical scholarship has rarely addressed the body and figure of the corpse, preferring to focus instead on the machinations of the femme fatale, the performance of masculinity, or the prevalence of violence. I cast new light on the world of hardboiled detective fiction by dissecting the corpse as the object that both motivates and de-composes (or rots away from) the narrative that makes it signify. I treat the corpse as an inanimate object, indifferent to representation, that destabilizes the integrity and self-possession, as well as the ratiocination, of the detective who authors the narrative of how the corpse came to be. The corpse is all deceptive and dangerous surface rather than the container of hidden depths of life and meaning that the detective hopes to uncover and reconstruct. I conclude with a chapter that is both critical denouement and creative writing experiment to reveal the self-reflexive (and at times metafictional) dimensions of hardboiled fiction. My dissertation, too, in the manner of hardboiled fiction, hopes to incriminate my readers as much as enlighten them.

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.

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.
