Mündliche Literatur in Amadou Hampaté Bâ’s Roman "Das seltsame Schicksal des Wangrin" /// Arbeitspapiere / Institut für Ethnologie und Afrikastudien ; 90

Amadou Hampaté Bâ legte mit „Das seltsame Schicksal des Wangrin“ einen vielstimmigen Roman vor, dessen Ästhetik entscheidend von der Einarbeitung und Inszenierung von Mündlicher Literatur bestimmt ist. In meinem Aufsatz gehe ich zum einen der Frage nach, inwieweit es Bâ unternimmt, den sinnlichen Reichtum Mündlicher Literatur, also entsprechende Sounds, Gestik, Mimik, Proxemik, musikalische Begleitung, in den einen graphischen Kommunikationskanal, in Schrift zu überführen, und zum anderen, inwiefern er die sprachlichen Anteile Mündlicher Literatur in das Romanganze hineinwebt, inwiefern er Verbindungen zwischen den Oraturen und den im Roman aufgerufenen sozialen Situationen herstellt. Im Zentrum der Untersuchung steht ein bestimmter Vortrag. Der Romanheld Wangrin lässt sich vor dem Haus der Mutter der von ihm umworbenen Rammaye Bira durch seinen Griot preisen, wirbt solcherart um die junge Frau. Herman Meyers Konzept der epischen Integration aufgreifend, lege ich dar, inwiefern diese eine Performanzsituation mit anderen Stellen, an denen im Roman Mündliche Literatur inszeniert wird, korrespondiert, um dadurch zu generelleren Aussagen über die Verfahrensweise Bâ’s hinsichtlich der Aufnahme von Mündlicher Literatur zu gelangen. Am Anfang des Aufsatzes fasse ich Charakteristika Mündlicher Literatur zusammen und problematisiere deren Überführung in den schriftlichen Modus.

Oxygen-containing polycyclic aromatic hydrocarbons (OPAHs) and their parent-PAHs in soil

In spite of the higher toxicity of oxygen-containing polycyclic aromatic hydrocarbons (OPAHs) than of their parent-PAHs, there are only a few studies of the concentrations, composition pattern, sources and fate of OPAHs in soil, the presumably major environmental sink of OPAHs. This is related to the fact that there are only few available methods to measure OPAHs together with PAHs in soil. rnThe objectives of my thesis were to (i) develop a GC/MS-based method to measure OPAHs and their parent-PAHs in soils of different properties and pollution levels, (ii) apply the method to soils from Uzbekistan and Slovakia and (iii) investigate into the fate of OPAHs, particularly their vertical transport in soilrnI optimized and fully evaluated an analytical method based on pressurized liquid extraction, silica gel column chromatographic fractionation of extracted compounds into alkyl-/parent-PAH and OPAH fractions, silylation of hydroxyl-/carboxyl-OPAHs with N,O-bis(trimethylsilyl)trifluoracetamide and GC/MS quantification of the target compounds. The method was targeted at 34 alkyl-/parent-PAHs, 7 carbonyl-OPAHs and 19 hydroxyl-/carboxyl-OPAHs. I applied the method to 11 soils from each of the Angren industrial region (which hosts a coal mine, power plant, rubber factory and gold refinery) in Uzbekistan and in the city of Bratislava, the densely populated capital of Slovakia.rnRecoveries of five carbonyl-OPAHs in spike experiments ranged between 78-97% (relative standard deviation, RSD, 5-12%), while 1,2-acenaphthenequinone and 1,4-naphtho-quinone had recoveries between 34-44%% (RSD, 19-28%). Five spiked hydroxyl-/carboxyl-OPAHs showed recoveries between 36-70% (RSD, 13-46%), while others showed recoveries <10% or were completely lost. With the optimized method, I determined, on average, 103% of the alkyl-/parent-PAH concentrations in a certified reference material.rnThe ∑OPAHs concentrations in surface soil ranged 62-2692 ng g-1 and those of ∑alkyl-/parent-PAHs was 842-244870 ng g-1. The carbonyl-OPAHs had higher concentrations than the hydroxyl-/carboxyl-OPAHs. The most abundant carbonyl-OPAHs were consistently 9-fluorenone (9-FLO), 9,10-anthraquinone (9,10-ANQ), 1-indanone (1-INDA) and benzo[a]anthracene-7,12-dione (7,12-B(A)A) and the most abundant hydroxyl-/carboxyl-OPAH was 2-hydroxybenzaldehyde. The concentrations of carbonyl-OPAHs were frequently higher than those of their parent-PAHs (e.g., 9-FLO/fluorene >100 near a rubber factory in Angren). The concentrations of OPAHs like those of their alkyl-/parent-PAHs were higher at locations closer to point sources and the OPAH and PAH concentrations were correlated suggesting that both compound classes originated from the same sources. Only for 1-INDA and 2-biphenylcarboxaldehyde sources other than combustion seemed to dominate. Like those of the alkyl-/parent-PAHs, OPAH concentrations were higher in topsoils than subsoils. Evidence of higher mobility of OPAHs than their parent-PAHs was provided by greater subsoil:topsoil concentration ratios of carbonyl-OPAHs (0.41-0.82) than their parent-PAHs (0.41-0.63) in Uzbekistan. This was further backed by the consistently higher contribution of more soluble 9-FLO and 1-INDA to the ∑carbonyl-OPAHs in subsoil than topsoil at the expense of 9,10-ANQ, 7,12-B(A)A and higher OPAH/parent-PAH concentration ratios in subsoil than topsoil in Bratislava.rnWith this thesis, I contribute a suitable method to determine a large number of OPAHs and PAHs in soil. My results demonstrate that carbonyl-OPAHs are more abundant than hydroxyl-/carboxyl-OPAHs and OPAH concentrations are frequently higher than parent-PAH concentrations. Furthermore, there are indications that OPAHs are more mobile in soil than PAHs. This calls for appropriate legal regulation of OPAH concentrations in soil.

Genetic dynamics across early life stages in the tropical tree Prunus africana (Rosaceae)

In many plant species, the genetic template of early life-stages is formed by animal-mediated pollination and seed dispersal and has profound impact on further recruitment and population dynamics. Understanding the impact of pollination and seed dispersal on genetic patterns is a central issue in plant population biology. In my thesis, I investigated (i) contemporary dispersal and gene flow distances as well as (ii) genetic diversity and spatial genetic structure (SGS) across subsequent recruitment stages in a population of the animal-pollinated and dispersed tree Prunus africana in Kakamega Forest, West Kenya. Using microsatellite markers and parentage analyses, I inferred distances of pollen dispersal (father-to-mother), seed dispersal/maternal gene flow (mother-to-offspring) as well as paternal gene flow (father-to-offspring) for four early life stages of the species (seeds and fruits, current year seedlings, seedlings ≤ 3yr, seedlings > 3yr). Distances of pollen and seed dispersal as well as paternal gene flow were significantly shorter than expected from the spatial arrangement of trees and sampling plots. They were not affected by the density of conspecific trees in the surrounding. At the propagule stage, mean pollen dispersal distances were considerably (23-fold) longer than seed dispersal distances, and paternal gene flow distances exceeded maternal gene flow by a factor of 25. Seed dispersal distances were remarkably restricted, potentially leading to a strong initial SGS. The initial genetic template created by pollination and seed dispersal was extensively altered during later recruitment stages. Potential Janzen-Connell effects led to markedly increasing distances between offspring and both parental trees in older life stages. This showed that distance and density-dependent mortality factors are not exclusively related to the mother tree, but also to the father. Across subsequent recruitment stages, the pollen to seed dispersal ratio and the paternal to maternal gene flow ratio dropped to 2.1 and 3.4, respectively, in seedlings > 3yr. The relative changes in effective pollen dispersal, seed dispersal, and paternal gene flow distances across recruitment stages elucidate the mechanisms affecting the contribution of the two processes pollen and seed dispersal to overall gene flow. Using the same six microsatellite loci, I analyzed genetic diversity and SGS across five life stages, from seed rain to adults. Levels of genetic diversity within the studied P. africana population were comparable to other Prunus species and did not vary across life stages. In congruence with the short seed dispersal distances, I found significant SGS in all life stages. SGS decreased from seed and early seedling stages to older juvenile stages, and it was higher in adults than in late juveniles of the next generation. A comparison of the data with direct assessments of contemporary gene flow patterns indicate that distance- or density-dependent mortality, potentially due to Janzen-Connell effects, led to the initial decrease in SGS. Intergeneration variation in SGS could have been driven by variation in demographic processes, the effect of overlapping generations, and local selection processes. Overall, my study showed that complex sequential processes during recruitment contribute to the spatial genetic structure of tree populations. It highlights the importance of a multistage perspective for a comprehensive understanding of the impact of animal-mediated pollen and seed dispersal on spatial population dynamics and genetic patterns of trees.

Development and evaluation of a 44 Ti, 44 Sc radionuclide generator and labeling of biomolecules with 44 Sc and 68 Ga for PET imaging

Non-invasive molecular-imaging technologies are playing a key role in drug discovery, development and delivery. Positron Emission Tomography (PET) is such a molecular imaging technology and a powerful tool for the observation of various deceases in vivo. However, it is limited by the availability of vectors with high selectivity to the target and radionuclides with a physical half-life which matches the biological half-life of the observed process. The 68Ge/68Ga radionuclide generator makes the PET-nuclide anywhere available without an on-site cyclotron. Besides the perfect availability 68Ga shows well suited nuclide properties for PET, but it has to be co-ordinated by a chelator to introduce it in a radiopharmaceuticals.rnHowever, the physical half-life of 68Ga (67.7 min) might limit the spectrum of clinical applications of 68Ga-labelled radiodiagnostics. Furthermore, 68Ga-labelled analogues of endoradiotherapeuticals of longer biological half-live such as 90Y- or 177Lu-labeled peptides and proteins cannot be used to determine individual radiation dosimetry directly. rnThus, radionuclide generator systems providing positron emitting daughters of extended physical half-life are of renewed interest. In this context, generator-derived positron emitters with longer physical half-life are needed, such as 72As (T½ = 26 h) from the 72Se/72As generator, or 44Sc (T½ = 3.97 h) from the 44Ti/44Sc generator.rnIn this thesis the implementation of radioactive gallium-68 and scandium-44 for molecular imaging and nuclear medical diagnosis, beginning with chemical separation and purification of 44Ti as a radionuclide mother, investigation of pilot generators with different elution mode, building a prototype generator, development and investigation of post-processing of the generator eluate, its concentration and further purification, the labeling chemistry under different conditions, in vitro and in vivo studies of labeled compounds and, finally, in vivo imaging experiments are described.

L'agentività dell'interprete-figlia: un case study di interpretazione ad-hoc in contesto medico

In dieser Masterarbeit wird ein, aus einer Interaktion bzw. einem gedolmetschten medizinischen Aufklärungsgespräch bestehendes Korpus mithilfe der Instrumente und der methodischen Vorgehensweise der Konversationsanalyse untersucht. Die Gesprächspartner sind ein privater Arzt, eine Patientin und ihre, als Dolmetscherin fungierende Tochter. Die Untersuchung des Gesprächsverhaltens der Ad-hoc-Dolmetscherin durch die Anwendung der participation framework Theorie dient zur Festlegung der folgenden, nicht a priori festgelegten Verhaltensmuster: Die Dolmetscherin nimmt de facto im Gespräch eine invasive Rolle ein, die auf die Umstände ihrer Zweisprachigkeit und ihres Verwandtheitsgrades zur Patientin zurückzuführen ist. Die Tochter der Patientin – eine ausgebildete Krankenpflegerin – agiert als Laiengesprächsdolmetscherin, da sie zu einem früheren Zeitpunkt als ihre Mutter ins Gastland ausgewandert ist und die Landessprache bereits gemeistert hat. Es wird also erstmals das Bild der medizinisch ausgebildeten dolmetschenden Tochter geprägt, die die markante Tendenz aufweist, eine Advocate- und Proxyrolle einzunehmen, welche konversational als nicht neutral eingestuft wird. Dies scheint trotzdem die Qualität des gedolmetschten Textes nicht zu beeinträchtigen, da die Kommunikation zumeist reibungslos verläuft, obwohl die widergegebenen Inhalte sichtlich manipuliert werden. Aus der Analyse der gewählten Gesprächssituation lässt sich schließen, dass diese Ad-Hoc Dolmetscherin, die – im Fall des behandelten Gesprächs aus beruflichen Gründen – im behandelten medizinischen Fachbereich ausreichendes Hintergrundwissen aufweist, verglichen mit jenen Ad-Hoc Dolmetschern, die nicht über dieses Wissen verfügen, trotz stellenweiser fehlerhafter Dolmetschung und Abänderung der gesprochenen Inhalte kaum Missverständnisse aufwirft und so einen vergleichsweise ungestörten Gesprächsfluss ermöglicht.

Shading Silhouettes of Smaller Ones

I am truly honored to have been given the amazing opportunity to create this original piece, this powerful journey through memory and emotive exploration of the loss of childhood. How do we feel about the loss of our child-self? Could we ever get them back? How long, how deep would one have to dig in the graveyards, the playgrounds of memory, to uncover what was buried there... to un-erase what waserased? shading silhouettes of smaller ones will ultimately encourage a reconnection with the Inner Child hidden inside all of us, as well as an intimate awareness of the adult version of the self by looking back to the smaller ones. The main inspiration for this piece is then of course, Inner Child Work. Most people may not be familiar with this therapeutic exploration of childhood... It wasimportant to me then, to present this concept in an imaginative, theatrical way, as a gift to you - a comprehensive and intensely moving gift. Speaking from experience, working on my Inner Child - my little Bianca - has been the most painful, frightening, yetrewarding and powerful experience within my personal life. Some people spend their entire lives trying to love themselves, to prove themselves, or be accepted. Some are too afraid to look back to where it all began. The characters within this piece will face thatfear... in a regression from the complexities of adulthood to the confusion of adolescence, all the way back to the wonder and bliss of childhood. They will reveal memories, of both joy and pain, love and abandonment, journeying backwards through time - through memory - through a playground - back to the beginning... We will enter a world where a push of a merry-go-round spins us to games of Truth or Dare after a high school dance at 16 - or the slam of a metal fence reminds us of the door Dad slammed in our face at 9 - where the sound of chain links swings us back to scrapping our knee by the sandbox at 5 This piece will attempt to connect everyone, both cast and audience, through a universal understanding and discussion of what it means to grow up, as well as a discovery of WHY we are the way we are - how experiences or relationships from our childhood have shaped our adult lives. We will attempt to challenge your honesty and nerve by inviting you to ask questions of yourselves, your past - to remember what it's like to have the innocence and hope of a child, to engage with and discover your Inner Child, to realize when or why you left them behind, and if you want to this magical part of yourself. It is my hope that you will join us in a collective journey - gather the courage to dig up the little kid you buried so long ago...* The creation, design, choreography, and direction for shading silhouettes of smaller ones mark the culminating experience of a year-long independent study in Theatre.

Targeted next generation sequencing as a diagnostic tool in epileptic disorders

Epilepsies have a highly heterogeneous background with a strong genetic contribution. The variety of unspecific and overlapping syndromic and nonsyndromic phenotypes often hampers a clear clinical diagnosis and prevents straightforward genetic testing. Knowing the genetic basis of a patient's epilepsy can be valuable not only for diagnosis but also for guiding treatment and estimating recurrence risks.

Validity and responsiveness of the Core Outcome Measures Index (COMI) for the neck

Patient-orientated outcome questionnaires are essential to evaluate treatment success. To compare different treatments, hospitals, and surgeons, standardised questionnaires are required. The present study examined the validity and responsiveness of the Core Outcome Measurement Index for neck pain (COMI-neck), a short, multidimensional outcome instrument.

Les incitations à l'investissement et la relance des investissements au Cameroun

Depuis l’accession du Cameroun à l’indépendance, les autorités du pays ont été conscientes de la nécessité pour elles d’attirer les investissements pour atteindre leurs objectifs de développement. Cette volonté de promouvoir l’investissement s’est traduite aussi bien par l’adoption de textes législatifs et réglementaires encourageant l’investissement , de même par l’adoption de politiques publiques en faveur des investisseurs. Ces différentes mesures ont produit le résultat que chacun de nous constate chaque jour que Dieu nous permet de vivre sur cette terre. Pourtant, tout n’est pas perdu. Le Cameroun possède en son sein les ressources ainsi que les instruments nécessaires à son salut. Ceux qui en parcourant les lignes qui précèdent auront l’impression que rien de nouveau n’a été fait aurons raison, car tout ce qu’il nous faut a toujours été entre nos mains. Il ne nous reste qu’à nous armer du courage pour les mettre en œuvre. Dans la dure bataille qui l’attend, le gouvernement du Cameroun doit faire de la théorie du droit qui au Cameroun, s’est donné pour mission de rechercher des solutions innovantes, voir inédites aux problèmes du Cameroun. C’est une alliée précieuse pour remporter la victoire dans la guerre contre la pauvreté et la souffrance dans le pays. Avant de terminer, nous allons avoir le dernier mot pour ceux qui bienpensant rejetterons ce papier comme inutile, l’intention de l’auteur n’était pas de poser de nouvelles règles pour l’encadrement de notre société, mais bien de considérer quelques chiffres : 21 millions, c’est le nombre estimé d’habitants du Cameroun en 2013, 43% ont moins de 15 ans Cela signifie à peu près 10 millions de personnes pour lesquelles il faudra tout inventer, tout créé, tout tenté. Puisse ces données produire en chaque camerounais le sursaut nécessaire pour faire comme le président de la république l’a indiqué dans son discours d’investiture en novembre 2011 : oser

Duplication of the sodium channel gene cluster on 2q24 in children with early onset epilepsy

Sodium channel gene aberrations are associated with a wide range of seizure disorders, particularly Dravet syndrome. They usually consist of missense or truncating gene mutations or deletions. Duplications involving multiple genes encoding for different sodium channels are not widely known. This article summarizes the clinical, radiologic, and genetic features of patients with 2q24 duplication involving the sodium channel gene cluster.

Adapting health-risk communication to the specific cultural contexts of diverse populations : an assessment of malaria-treatment programs in Liberia

Drawing on theories of technical communication, rhetoric, literacy, language and culture, and medical anthropology, this dissertation explores how local culture and traditions can be incorporated into health-risk-communication-program design and implementation, including the design and dissemination of health-risk messages. In a modern world with increasing global economic partnerships, mounting health and environmental risks, and cross-cultural collaborations, those who interact with people of different cultures have “a moral obligation to take those cultures seriously, including their social organization and values” (Hahn and Inhorn 10). Paradoxically, at the same time as we must carefully adapt health, safety, and environmental-risk messages to diverse cultures and populations, we must also recognize the increasing extent to which we are all becoming part of one, vast, interrelated global village. This, too, has a significant impact on the ways in which healthcare plans should be designed, communicated, and implemented. Because communicating across diverse cultures requires a system for “bridging the gap between individual differences and negotiating individual realities” (Kim and Gudykunst 50), both administrators and beneficiaries of malaria-treatment-and-control programs (MTCPs) in Liberia were targeted to participate in this study. A total of 105 people participated in this study: 21 MTCP administrators (including designers and implementers) completed survey questionnaires on program design, implementation, and outcomes; and 84 MTCP beneficiaries (e.g., traditional leaders and young adults) were interviewed about their knowledge of malaria and methods for communicating health risks in their tribe or culture. All participants showed a tremendous sense of courage, commitment, resilience, and pragmatism, especially in light of the fact that many of them live and work under dire socioeconomic conditions (e.g., no electricity and poor communication networks). Although many MTCP beneficiaries interviewed for this study had bed nets in their homes, a majority (46.34 percent) used a combination of traditional herbal medicine and Western medicine to treat malaria. MTCP administrators who participated in this study rated the impacts of their programs on reducing malaria in Liberia as moderately successful (61.90 percent) or greatly successful (38.10 percent), and they offered a variety of insights on what they might do differently in the future to incorporate local culture and traditions into program design and implementation. Participating MTCP administrators and beneficiaries differed in their understanding of what “cultural incorporation” meant, but they agreed that using local indigenous languages to communicate health-risk messages was essential for effective health-risk communication. They also suggested that understanding the literacy practices and linguistic cultures of the local people is essential to communicating health risks across diverse cultures and populations.

Ungarische Sexarbeiterinnen in Zürich zwischen Marginalisierung und Selbstbestimmung

Seit 2008 arbeiten vermehrt Roma-Frauen (Romnija) aus dem Nordosten Ungarns in westeuropäischen Städten auf dem Straßenstrich. Sie haben in den Jahren davor mit ihren Körpern Prostitutionsorte in Ungarn konstituiert bis schließlich die Prostitutionsverordnung von staatlicher Seite neu interpretiert wurde. Heute verändern sie Räume in Städten wie Amsterdam und Zürich. Mit ihrer Entscheidung, Sex an legalen Orten in Europa anzubieten, versuchen sie ihre Familien finanziell zu unterstützen. So wurden sie von einer durch ein patriarchalisches System geprägten Romni zur transnationa-len Mutter, Arbeitsmigrantin, Ausländerin und Sexarbeiterin. Diese neue Wirklichkeit führte nicht nur zu räumlichen Veränderungen an den verschiedensten Orten in Europa, sondern auch zu einem Wandel mit ethnischen, sozialen und geschlechterspezifischen Dimensionen.

Geschlechtsuntypische Berufswahlen bei jungen Frauen: Muss das Vorbild weiblich sein?

Im Zentrum des vorliegenden Beitrags steht die Analyse der Bedeutung elterlicher Vorbilder für eine geschlechtsuntypische Berufswahl bei jungen Frauen. Die Fragestellungen werden auf der Datengrundlage einer standardisierten Befragung von Jugendlichen, die in beruflicher Ausbildung stehen (N = 1431), untersucht. Die Ergebnisse zeigen, dass die Familie für Jugendliche ein wichtiger Herkunftsbereich für Vorbilder darstellt, wobei Mutter und Vater am häufigsten als Vorbilder genannt werden. Zudem wird ersichtlich, dass Jugendliche zumeist gleichgeschlechtliche Vorbilder wählen. Weibliche Jugendliche verhalten sich bei der Wahl ihrer Vorbilder jedoch weniger geschlechterstereotyp als männliche Jugendliche, die fast nur Personen gleichen Geschlechts als Vorbilder wählen. Im Hinblick auf die elterliche Vorbildfunktion bei der Berufswahl zeigen unsere Ergebnisse, dass die Wahrscheinlichkeit der Wahl eines frauenuntypischen Berufs durch junge Frauen am größten ist, wenn deren Mutter oder Vater einen männertypischen oder geschlechtsneutralen Beruf ausüben.
