Vertraute Fremde? Jens Baggesens und H.C. Andersens Reisen durch Deutschland:Fremdheitswahrnehmung und ihre literarische Gestaltung in "Labyrinten" und "Skyggebilleder"

Jens Baggesen and H.C. Andersen are both aspiring young authors when they set out on their respective journeys to Germany. The literary accounts of their travels - Labyrinten and Skyggebilleder - show how the authors perceive a foreign country, which, despite having a culture closely linked to their own, still contains elements that strike them as being unfamiliar and even bizarre. Their curiosity towards the strange features they encounter is accompanied by a strong desire to reaffirm their own national and cultural identity, forever relying on the comfort of the familiar. When confronted with experiences of strangeness and unfamiliarity that threaten to alienate them, both authors develop similar literary strategies. The poetical programmes that both writers implicitly subscribe to are illustrated in the way they perceive strange and alien elements and are therefore fundamentally and intrinsically interlinked with their aesthetic convictions as writers.

A gazdaságpolitikai döntéshozatal nemzetek fölötti centralizációja és a közösségi gazdaságtan. Az adóverseny elméletének néhány tanulsága (Supranational centralization of economic policy-making and community economics: some lessons from the theory of tax competition)

Mennyiben képes jelenleg a közösségi gazdaságtan az adópolitikák nemzetek fölötti centralizációjára vonatkozó politikai döntések megalapozására? Válaszunk röviden az lesz, hogy a közösségi gazdaságtan főárama - noha számos releváns gazdasági és politikai tényező hatását sikeresen elemzi - jelenleg nem kínál kielégítőnek tekinthető döntési kritériumokat a döntéshozók számára. Ennek oka, hogy központi szerepet játszik benne egy, a modellek szempontjából exogén és a közgazdasági elmélettől idegen tényező: a kormányzatok jóindulatára, pontosabban annak mértékére vonatkozó premissza. Tanulmányunk az adóverseny fiskális föderalista elméletét vizsgálja, és megpróbál általánosabb szinten is a közszektor gazdaságelméletének jelenlegi állapotára, valamint továbbfejlesztésére vonatkozó tanulságokat levonni. A kiutat az elméleti zsákutcából a kormányzati működés és döntéshozatal, valamint a kívánatos gazdaságpolitikai döntések elméletének összekapcsolása jelentheti. Erre megtörténtek az első kísérletek, de a szisztematikus és átfogó elemzés egyelőre várat magára. / === / How far can community economics provide a basis for political decision-making on supranational centralization of taxation policies? The short answer here will be that although the mainstream of community economics succeeds in analysing many relevant economic and political factors, it fails at present to provide satisfactory criteria for decisionmakers. This is because a central role is played in it by a factor exogenous to the models and alien to economic theory: the premise of the measure of goodwill from governments. The study examines the fiscal federalist theory of tax competition. It tries to draw conclusions, on a more general level, about the present state of the economic theory of the public sector and future development of it. The way out of the theoretical blind alley could be to link the theories of government operation and decision-making and of desirable economic-policy decision-making. The first attempts to do so have been made, but a systematic and comprehensive analysis is still awaited.

Neumann versus Leontief. Két modell – két gazdaságkép (Neumann vs Leontief. Two models, two approaches to the economy)

A szerző a tisztán elméleti célokra kifejlesztett Neumann-modellt és a gyakorlati alkalmazások céljára kifejlesztett Leontief-modellt veti össze. A Neumann-modell és a Leontief-modell éves termelési periódust feltételező, zárt, stacionárius változatának hasonló matematikai struktúrája azt a feltételezést sugallja, hogy az utóbbi a Neumann-modell sajátos eseteként értelmezhető. Az egyes modellek közgazdasági tartalmát és feltevéseit részletesen kibontva és egymással összevetve a szerző megmutatja, hogy a fenti következtetés félrevezető, két merőben különböző modellről van szó, nem lehet az egyikből a másikat levezetni. Az ikertermelés és technológiai választék lehetősége a Neumann-modell elengedhetetlen feltevése, az éves termelési periódus feltevése pedig kizárja folyam jellegű kibocsátások explicit figyelembevételét. Mindezek feltevések ugyanakkor idegenek a Leontief-modelltől. A két modell valójában egy általánosabb állomány–folyam jellegű zárt, stacionárius modell sajátos esete, méghozzá azok folyamváltozókra redukált alakja. _____ The paper compares the basic assumptions and methodology of the Von Neumann model, developed for purely abstract theoretical purposes, and those of the Leontief model, designed originally for practical applications. Study of the similar mathematical structures of the Von Neumann model and the closed, stationary Leontief model, with a unit length of production period, often leads to the false conclusion that the latter is just a simplified version of the former. It is argued that the economic assumptions of the two models are quite different, which makes such an assertion unfounded. Technical choice and joint production are indispensable features of the Von Neumann model, and the assumption of unitary length of production period excludes the possibility of taking service flows explicitly into account. All these features are completely alien to the Leontief model, however. It is shown that the two models are in fact special cases of a more general stock-flow stationary model, reduced to forms containing only flow variables.

Multiple predator effects and native prey responses to two non-native Everglades cichlids

Non-native predators may have negative impacts on native communities, and these effects may be dependent on interactions among multiple non-native predators. Sequential invasions by predators can enhance risk for native prey. Prey have a limited ability to respond to multiple threats since appropriate responses may conflict, and interactions with recent invaders may be novel. We examined predator–prey interactions among two non-native predators, a recent invader, the African jewelfish, and the longer-established Mayan cichlid, and a native Florida Everglades prey assemblage. Using field enclosures and laboratory aquaria, we compared predatory effects and antipredator responses across five prey taxa. Total predation rates were higher for Mayan cichlids, which also targeted more prey types. The cichlid invaders had similar microhabitat use, but varied in foraging styles, with African jewelfish being more active. The three prey species that experienced predation were those that overlapped in habitat use with predators. Flagfish were consumed by both predators, while riverine grass shrimp and bluefin killifish were eaten only by Mayan cichlids. In mixed predator treatments, we saw no evidence of emergent effects, since interactions between the two cichlid predators were low. Prey responded to predator threats by altering activity but not vertical distribution. Results suggest that prey vulnerability is affected by activity and habitat domain overlap with predators and may be lower to newly invading predators, perhaps due to novelty in the interaction.

Conjugated polymer nanoparticles for effective siRNA delivery to tobacco BY-2 protoplasts

Background Post transcriptional gene silencing (PTGS) is a mechanism harnessed by plant biologists to knock down gene expression. siRNAs contribute to PTGS that are synthesized from mRNAs or viral RNAs and function to guide cellular endoribonucleases to target mRNAs for degradation. Plant biologists have employed electroporation to deliver artificial siRNAs to plant protoplasts to study gene expression mechanisms at the single cell level. One drawback of electroporation is the extensive loss of viable protoplasts that occurs as a result of the transfection technology. Results We employed fluorescent conjugated polymer nanoparticles (CPNs) to deliver siRNAs and knockdown a target gene in plant protoplasts. CPNs are non toxic to protoplasts, having little impact on viability over a 72 h period. Microscopy and flow cytometry reveal that CPNs can penetrate protoplasts within 2 h of delivery. Cellular uptake of CPNs/siRNA complexes were easily monitored using epifluorescence microscopy. We also demonstrate that CPNs can deliver siRNAs targeting specific genes in the cellulose biosynthesis pathway (NtCesA-1a and NtCesA-1b). Conclusions While prior work showed that NtCesA-1 is a factor involved in cell wall synthesis in whole plants, we demonstrate that the same gene plays an essential role in cell wall regeneration in isolated protoplasts. Cell wall biosynthesis is central to cell elongation, plant growth and development. The experiments presented here shows that NtCesA is also a factor in cell viability. We show that CPNs are valuable vehicles for delivering siRNAs to plant protoplasts to study vital cellular pathways at the single cell level.

Da educação infantil ao ensino fundamental: o que contam as crianças sobre essa travessia na cultura de escola

From inquiries concerning the child as an individual with rights, this work takes as its object of study the perception of 5-7 years old children on their journey from kindergarten to elementary school, in a school culture. The objective of the research is, therefore, to investigate what the children tell in narratives drawn into a conversation circle about their experiences of school life in kindergarten and the first grade of elementary school. The participants were 18 children from a public school in the city of Natal (RN). Five rounds of conversation were held in which the children told a little alien, who was unaware of the school culture, what they knew about school and what they did at it. The research is linked to the project "Children's Narratives. What the children tell about childhood schools?"(Passeggi et all, 2011) and adopts epistemological principles and research methods of (auto)biographical education, taking as a working hypothesis the child's ability to reflect on their experiences and understand from their point of view, what happens to them. Analyses were organized based on the concept of school culture (Barroso, 2012). In the narratives of children, the three dimensions of school culture: the functionalist (purpose and rules), structural (structure and pedagogical organization) and the interactional (relations with others, with the spaces and with knowledge) are considered intertwined in their school perceptions and signal experienced tensions in a process of "conversion" from child to student. Children seem to realize the uniqueness of each level of education. They recognize as a characteristic of early childhood education the recreational activities, and as injunctions of the first year of elementary school the "study", "learning to read and write" to "be smart" to "change." The schooling will thus, constitute, in their eyes, as a time and a place where the children's culture gives way to school culture, and in this journey they experience that the desire to play and the duty/want to study cross the three dimensions of school. At the end of the journey, the status of children as cultural beings with rights is confirmed, whose narratives about school and about their experiences of "conversion" in a student, reveal much about the power of reflection on themselves, the school and the society in which they live, legitimizing their place in educational research and in child care policies.

“CAMINHOS PARA DEUS” PROPOSTAS RELIGIOSAS DIVERGENTES E IDENTIDADE DO GRUPO JOANINO: UMA LEITURA EM JOÃO 13.33-14.31

No Quarto Evangelho Jesus se apresenta por meio de metáforas, sendo o objeto de nossa pesquisa a frase: “Eu sou o caminho, e a verdade, e a vida”, que será o ponto de partida condutor em busca da identidade do grupo joanino. No final do primeiro século, o grupo joanino se entende como fiéis herdeiros de Jesus, agora seguidores do discípulo João (filho de Zebedeu), o qual caminhou com Jesus. O grupo não se apresenta alheio à realidade da multiplicidade religiosa do período, mas está atento aos conflitos e aos caminhos divergentes para Deus. Isso nos aponta o quão identitário é o tema. A partir de uma leitura em João 13.33-14.31, nossa dissertação tem como objeto o modo como o grupo joanino recebe essa mensagem no imaginário, a exterioriza e reage no cotidiano, bem como os grupos posteriores do gnosticismo —como o Evangelho da Verdade da Biblioteca Copta de Nag Hammadi, elaborado a partir de leituras ulteriores que plasmam o mundo simbólico imaginário, cultivando diferentes características de pertença, gerando a identidade do grupo joanino.

Spaces of Order: An African Poetics of Space

“Spaces of Order” argues that the African novel should be studied as a revolutionary form characterized by aesthetic innovations that are not comprehensible in terms of the novel’s European archive of forms. It does this by mapping an African spatial order that undermines the spatial problematic at the formal and ideological core of the novel—the split between a private, subjective interior, and an abstract, impersonal outside. The project opens with an examination of spatial fragmentation as figured in the “endless forest” of Amos Tutuola’s The Palmwine Drinkard (1952). The second chapter studies Chinua Achebe’s Things Fall Apart (1958) as a fictional world built around a peculiar category of space, the “evil forest,” which constitutes an African principle of order and modality of power. Chapter three returns to Tutuola via Ben Okri’s The Famished Road (1991) and shows how the dispersal of fragmentary spaces of exclusion and terror within the colonial African city helps us conceive of political imaginaries outside the nation and other forms of liberal political communities. The fourth chapter shows Nnedi Okorafor—in her 2014 science-fiction novel Lagoon—rewriting Things Fall Apart as an alien-encounter narrative in which Africa is center-stage of a planetary, multi-species drama. Spaces of Order is a study of the African novel as a new logic of world making altogether.

Oxygen Utilization and Downward Carbon Flux in an Oxygen-Depleted Eddy in the Eastern Tropical North Atlantic

The occurrence of mesoscale eddies that develop suboxic environments at shallow depth (about 40-100 m) has recently been reported for the eastern tropical North Atlantic (ETNA). Their hydrographic structure suggests that the water mass inside the eddy is well isolated from ambient waters supporting the development of severe near-surface oxygen deficits. So far, hydrographic and biogeochemical characterization of these eddies was limited to a few autonomous surveys, with the use of moorings, under water gliders and profiling floats. In this study we present results from the first dedicated biogeochemical survey of one of these eddies conducted in March 2014 near the Cape Verde Ocean Observatory (CVOO). During the survey the eddy core showed oxygen concentrations as low as 5 µmol kg-1 with a pH of around 7.6 at approximately 100 m depth. Correspondingly, the aragonite saturation level dropped to 1 at the same depth, thereby creating unfavorable conditions for calcifying organisms. To our knowledge, such enhanced acidity within near-surface waters has never been reported before for the open Atlantic Ocean. Vertical distributions of particulate organic matter and dissolved organic matter (POM and DOM), generally showed elevated concentrations in the surface mixed layer (0-70 m), with DOM also accumulating beneath the oxygen minimum. With the use of reference data from the upwelling region where these eddies are formed, the oxygen utilization rate was calculated by determining oxygen consumption through the remineralization of organic matter. Inside the core, we found these rates were almost 1 order of magnitude higher (apparent oxygen utilization rate (aOUR); 0.26 µmol kg-1 day-1) than typical values for the open North Atlantic. Computed downward fluxes for particulate organic carbon (POC), were around 0.19 to 0.23 g C m-2 day-1 at 100 m depth, clearly exceeding fluxes typical for an oligotrophic open-ocean setting. The observations support the view that the oxygen-depleted eddies can be viewed as isolated, westwards propagating upwelling systems of their own, thereby represent re-occurring alien biogeochemical environments in the ETNA.

Projecting Changes in the Distribution and Productivity of Living Marine Resources: A Critical Review of the Suite of Modeling Approaches used in the Large European Project VECTORS

We review and compare four broad categories of spatially-explicit modelling approaches currently used to understand and project changes in the distribution and productivity of living marine resources including: 1) statistical species distribution models, 2) physiology-based, biophysical models of single life stages or the whole life cycle of species, 3) food web models, and 4) end-to-end models. Single pressures are rare and, in the future, models must be able to examine multiple factors affecting living marine resources such as interactions between: i) climate-driven changes in temperature regimes and acidification, ii) reductions in water quality due to eutrophication, iii) the introduction of alien invasive species, and/or iv) (over-)exploitation by fisheries. Statistical (correlative) approaches can be used to detect historical patterns which may not be relevant in the future. Advancing predictive capacity of changes in distribution and productivity of living marine resources requires explicit modelling of biological and physical mechanisms. New formulations are needed which (depending on the question) will need to strive for more realism in ecophysiology and behaviour of individuals, life history strategies of species, as well as trophodynamic interactions occurring at different spatial scales. Coupling existing models (e.g. physical, biological, economic) is one avenue that has proven successful. However, fundamental advancements are needed to address key issues such as the adaptive capacity of species/groups and ecosystems. The continued development of end-to-end models (e.g., physics to fish to human sectors) will be critical if we hope to assess how multiple pressures may interact to cause changes in living marine resources including the ecological and economic costs and trade-offs of different spatial management strategies. Given the strengths and weaknesses of the various types of models reviewed here, confidence in projections of changes in the distribution and productivity of living marine resources will be increased by assessing model structural uncertainty through biological ensemble modelling.

Concluyendo tras el análisis semántico de dibujos y relatos, que las imágenes representativas de la mujer en los videojuegos transgreden las identidades tradicionales de género al interior de un marco androcéntrico predominante.

Las edades de Hitler. De Satán a un ser de carne y hueso, y su representación en clave paródica

Adolf Hitler suscitó desde su entrada en la escena política alemana una fascinación perversa, un sentimiento que, con el tiempo, ha dado lugar a numerosas representaciones culturales sobre el Führer. La muestra, rica y variada tanto en el fondo como en la forma, nos permitirá trazar tres estadios en lo referente al proceso de construcción historiográfica del hitlerismo, iniciado con la caída del Tercer Reich. Estos responden en buena medida al devenir sociopolítico y cultural de la sociedad a escala global desde el final de la guerra y hasta nuestros días y pueden resumirse en tres: primero, la satanización; segundo, la humanización; tercero, el retrato caricaturesco. Proponemos un recorrido histórico por diversos productos culturales del dictador alemán cuyo propósito es desentrañar el retrato psicológico poliédrico que se ha construido en torno a la figura de Hitler.

"Unha espía no Reino de Galicia" de Manuel Rivas: O humor e a construción da identidade nacional galega

Este estudo analiza como Manuel Rivas aproveita a ambigüidade do concepto de estereotipo para crear una identidade cultural galega. En Unha espía no Reino de Galicia (2004), Rivas propón que a imaxe paródica do galego e o conxunto de trazos estereotipados que se lle asignan non son un elemento alleo a cultura galega, senón que é un trazo integral da dialéctica da súa identidade nacional. Desta maneira, ó feito diferencial galego, ademais da lingua, a unidade territorial, o celtismo, ou a emigración, habería que engadir a capacidade do galego de parodiar o seu propio discurso nacional.

Latina Super-heroines: Hot Tamales in Tights vs. Women Warriors, Wrestlers and Guerrilla Fighters of La Raza

The year 1977 saw the making of the first Latino superhero by a Latino artist. From the 1980s onwards it is also possible to find Latina super-heroines, whose number and complexity has kept increasing ever since. Yet, the representations of spandexed Latinas are still few. For that reason, the goal of this paper is, firstly, to gather a great number of Latina super-heroines and, secondly, to analyze the role that they have played in the history of American literature and art. More specifically, it aims at comparing the spandexed Latinas created by non-Latino/a artists and mainstream comic enterprises with the Latina super-heroines devised by Latino/a artists. The conclusion is that whereas the former tend to conceive heroines within the constraints of the logic of Girl Power, the latter choose to imbue their works with a more daring political content and to align their heroines with the ideologies of Feminism and Postcolonialism.
