Wirklichkeit und Fiktion in Günter Grass Im Krebsgang : Eine erzähltheoretische Analyse

Die Novelle, Im Krebsgang, von Günter Grass ist eine Mischung aus Zeitgeschichte, persönlicher Biografie des Autors und lebhafter Fantasie. Diese Komponenten auseinanderzuhalten könnte die Verständigung der Novelle verbessern. Nach den Annahmen, dass der engste Personenkreis um die Familie Pokriefke Fiktion ist, und die Geschichten um den U-Boot-Kommandanten Marinesko, den Medizinstudenten Frankfurter, den Nationalsozialisten Gustloff und das KdF-Schiff Wilhelm Gustloff faktual sind, wurden sechs Textabschnitte ausgewählt. Durch eine literaturwissenschaftliche Analyse dieser Textabschnitte wurden sechs Punkte gefunden, die die Trennlinie zwischen den fiktionalen und faktualen Textabschnitten identifizieren. Gefunden wurde, dass in den faktualen Texten der Erzähler immer auktorial, aus großer Distanz berichtet, und immer von der Fokalisierung getrennt ist. In den fiktionalen Texten aber liegt immer die Fokalisierung beim Erzähler, der stets szenisch erzählt.

Poverty as an Abuse of Human Rights in Ghana. : A grass roots perspective on poverty and human rights.

The study aimed at getting a grass root opinion on poverty and why Ghana is still poor after 50 years of independence in spite of her richness in natural resources, second largest producer of cocoa in the word and appreciable stable political environment. The opinions of the ordinary people in the Bia district and their observed living conditions was analysed in line with theoretical basis of the study and previous studies to justify the stance that poverty should be considered as an abuse of human rights. It was concluded based on position of informants and previous data available that though many factors have been raised by previous scholars as the cause of poverty, the actions and inactions of both internal and external power-holders is the main source of poverty in Ghana. It was proposed that for poverty to be reduced in a sustainable way there should be strong civil society groups and active citizens through civic education to hold power-holders accountable. Until the actions and inactions of power-holders which have subjected many Ghanaians into intergenerational poverty are seen as human rights abuse, the rights of many Ghanaians would be constantly abused. This will eventually defeat the promotion of human rights culture in Ghana.

Estimating the economic value of Mount Buffalo National Park with the travel cost and contingent valuation models

The Mount Buffalo National Park is the oldest national park in Victoria, Australia. There has been a rapid increase in the number of visitors to the park during the last decade and park management has been a concern, especially in the light of declining budgetary allocations and potential damage due to the increased visitor numbers. Policy options to increase park revenue remain unclear because of a lack of information on demand parameters and user costs. This study estimates the economic value of the park using the travel cost method (TCM) and the contingent valuation method (CVM). The TCM gives higher consumer surplus (CS) than the CVM. The CS shows that the economic value of the park is high and that there are opportunities to introduce innovative fee schemes to enhance its revenue. Present entry fee systems do not capture the economic value of the park.

Exotic grass fuel in south eastern Australia

One potentially serious impact of environmental weed invasion is an alteration to the fuel characteristics and subsequent fire regimes of an area. Considerable global evidence indicates that environmental weed invasion may produce 'new' fuel types, but there is little documented evidence of the impact of invasive exotic species on fuel characteristics and fire regimes in south-eastern Australia. This study on the impact of invasive exotic grasses in southeastern Australia has revealed major changes to fuel characteristics, particularly fuel loads.

Release of allergens in respirable aerosols : a link between grass pollen and asthma

Background: Asthma incidence has long been linked to pollen, even though pollen grains are too large to penetrate into the airways where asthmatic responses originate. Pollen allergens found in small, respirable particles have been implicated in a number of asthma epidemics, particularly ones following rainfall or thunderstorms.

Objective: The aim of this study was to determine how pollen allergens form the respirable aerosols necessary for triggering asthma.

Methods: Flowering grasses were humidified and then dried in a controlled-environment chamber connected to a cascade impactor and an aerosol particle counter. Particles shed from the flowers were analyzed with high-resolution microscopy and immunolabeled with rabbit anti-Phl p 1 antibody, which is specific for group 1 pollen allergens.

Results: Contrary to what has been reported in other published accounts, most of the pollen in this investigation remained on the open anthers of wind pollinated plants unless disturbed—eg, by wind. Increasing humidity caused anthers to close. After a cycle of wetting and drying followed by wind disturbance, grasses flowering within a chamber produced an aerosol of particles that were collected in a cascade impactor. These particles consisted of fragmented pollen cytoplasm in the size range 0.12 to 4.67 μm; they were loaded with group 1 allergens.

Conclusion: Here we provide the first direct observations of the release of grass pollen allergens as respirable aerosols. They can emanate directly from the flower after a moisture-drying cycle. This could explain asthmatic responses associated with grass pollination, particularly after moist weather conditions.

Cellular localization of water soluble, allergenic proteins in rye-grass (Lolium perenne) pollen using monoclonal and specific IgE antibodies with immunogold probes

A postembedding method has been developed for localizing water soluble allergens in rye-grass pollen. This uses dry fixation in glutaraldehyde vapour, followed by 2,2-dimethoxypropane, prior to a 100% ethanol series leading into embedment in LR Gold. This has allowed the attachment of specific monoclonal antibodies to the allergen, which are themselves probed with specific immunogold labels to the antibodies. Wall and cytoplasmic sites have been identified, representing an improvement of fixation and localization of allergens over previous studies employing polyclonal, broad spectrum antibodies.

Rye-grass allergens are labelled in mature pollen grains in the exine (tectum, nexine and central chamber), and in the electron opaque areas of the cytoplasm, especially mitochondria. The allergens are absent from the intine, polysaccharide (P) particles, amyloplasts, Golgi bodies and endoplasmic reticulum. IgE antibodies derived from humans allergic to rye-grass pollen, bind to similar sites in the cytoplasm but only to the outer surface of the pollen grain wall. This method now provides a valuable tool for further developmental studies on the pollen grains, in order to establish the site/s of synthesis of the allergens.
