Focus presuppositions
(2007)
This paper reviews notions related to focus and presupposition and addresses the hypothesis that focus triggers an existential presupposition. Presupposition projection behavior in certain examples appears to favor a presuppositional analysis of focus. It is argued that these examples are open to a different analysis using givenness theory. Overall, the analysis favors a weak semantics for focus not including an existential presupposition.
The aim of this work was the generation of carbon materials with high surface area, exhibiting a hierarchical pore system in the macro- and mesorange. Such a pore system facilitates the transport through the material and enhances the interaction with the carbon matrix (macropores are pores with diameters > 50 nm, mesopores between 2 – 50 nm). Thereto, new strategies for the synthesis of novel carbon materials with designed porosity were developed that are in particular useful for the storage of energy. Besides the porosity, it is the graphene structure itself that determines the properties of a carbon material. Non-graphitic carbon materials usually exhibit a quite large degree of disorder with many defects in the graphene structure, and thus exhibit inherent microporosity (d < 2nm). These pores are traps and oppose reversible interaction with the carbon matrix. Furthermore they reduce the stability and conductivity of the carbon material, which was undesired for the proposed applications. As one part of this work, the graphene structures of different non-graphitic carbon materials were studied in detail using a novel wide-angle x-ray scattering model that allowed precise information about the nature of the carbon building units (graphene stacks). Different carbon precursors were evaluated regarding their potential use for the synthesis shown in this work, whereas mesophase pitch proved to be advantageous when a less disordered carbon microstructure is desired. By using mesophase pitch as carbon precursor, two templating strategies were developed using the nanocasting approach. The synthesized (monolithic) materials combined for the first time the advantages of a hierarchical interconnected pore system in the macro- and mesorange with the advantages of mesophase pitch as carbon precursor. In the first case, hierarchical macro- / mesoporous carbon monoliths were synthesized by replication of hard (silica) templates. Thus, a suitable synthesis procedure was developed that allowed the infiltration of the template with the hardly soluble carbon precursor. In the second case, hierarchical macro- / mesoporous carbon materials were synthesized by a novel soft-templating technique, taking advantage of the phase separation (spinodal decomposition) between mesophase pitch and polystyrene. The synthesis also allowed the generation of monolithic samples and incorporation of functional nanoparticles into the material. The synthesized materials showed excellent properties as an anode material in lithium batteries and support material for supercapacitors.
Development and application of novel genetic transformation technologies in maize (Zea mays L.)
(2007)
Plant genetic engineering approaches are of pivotal importance to both basic and applied research. However, rapid commercialization of genetically engineered crops, especially maize, raises several ecological and environmental concerns largely related to transgene flow via pollination. In most crops, the plastid genome is inherited uniparentally in a maternal manner. Consequently, a trait introduced into the plastid genome would not be transferred to the sexually compatible relatives of the crops via pollination. Thus, beside its several other advantages, plastid transformation provides transgene containment, and therefore, is an environmentally friendly approach for genetic engineering of crop plants. Reliable in vitro regeneration systems allowing repeated rounds of regeneration are of utmost importance to development of plastid transformation technologies in higher plants. While being the world’s major food crops, cereals are among the most difficult-to-handle plants in tissue culture which severely limits genetic engineering approaches. In maize, immature zygotic embryos provide the predominantly used material for establishing regeneration-competent cell or callus cultures for genetic transformation experiments. The procedures involved are demanding, laborious and time consuming and depend on greenhouse facilities. In one part of this work, a novel tissue culture and plant regeneration system was developed that uses maize leaf tissue and thus is independent of zygotic embryos and greenhouse facilities. Also, protocols were established for (i) the efficient induction of regeneration-competent callus from maize leaves in the dark, (ii) inducing highly regenerable callus in the light, and (iii) the use of leaf-derived callus for the generation of stably transformed maize plants. Furthermore, several selection methods were tested for developing a plastid transformation system in maize. However, stable plastid transformed maize plants could not be yet recovered. Possible explanations as well as suggestions for future attempts towards developing plastid transformation in maize are discussed. Nevertheless, these results represent a first essential step towards developing chloroplast transformation technology for maize, a method that requires multiple rounds of plant regeneration and selection to obtain genetically stable transgenic plants. In order to apply the newly developed transformation system towards metabolic engineering of carotenoid biosynthesis, the daffodil phytoene synthase (PSY) gene was integrated into the maize genome. The results illustrate that expression of a recombinant PSY significantly increases carotenoid levels in leaves. The beta-carotene (pro-vitamin A) amounts in leaves of transgenic plants were increased by ~21% in comparison to the wild-type. These results represent evidence for maize to have significant potential to accumulate higher amounts of carotenoids, especially beta-carotene, through transgenic expression of phytoene synthases. Finally, progresses were made towards developing transformation technologies in Peperomia (Piperaceae) by establishing an efficient leaf-based regeneration system. Also, factors determining plastid size and number in Peperomia, whose species display great interspecific variation in chloroplast size and number per cell, were investigated. The results suggest that organelle size and number are regulated in a tissue-specific manner rather than in dependency on the plastid type. Investigating plastid morphology in Peperomia species with giant chloroplasts, plasmatic connections between chloroplasts (stromules) were observed under the light microscope and in the absence of tissue fixation or GFP overexpression demonstrating the relevance of these structures in vivo. Furthermore, bacteria-like microorganisms were discovered within Peperomia cells, suggesting that this genus provides an interesting model not only for studying plastid biology but also for investigating plant-microbe interactions.

Vor dem Hintergrund der Auffassung, dass ethnische Minderheiten eine Form so-zialer Organisation darstellen, verfolgt die Studie – unter Berücksichtigung der Mehr-deutigkeit des Raumbegriffs – das Ziel, anhand von Beispielen aus Rumänien ein Konzept zu entwickeln, mit dem sich die aktuelle Beziehung von Ethnizität und Raum im Transformationsprozess adäquat analysieren und beschreiben lässt.

The central melanin-concentrating hormone (MCH) system has been intensively studied for its involvement in the regulation of feeding behaviour and body weight regulation. The importance of the neuropeptide MCH in the control of energy balance has been underlined by MCH knock out and Melanin-concentrating hormone receptor subtype 1 (MCHR-1) knock-out animals. The anorectic and anti-obesity effects of selective MCHR-1 antagonists have confirmed the notion that pharmacological blockade of MCHR-1 is a potential therapeutic approach for obesity. First aim of this work is to study the neurochemical “equipment” of MCHR-1 immunoreactive neurons by double-labelling immunohistochemistry within the rat hypothalamus. Of special interest is the neuroanatomical identification of other hypothalamic neuropeptides that are co-distributed with MCHR-1. A second part of this study deals with the examination of neuronal activation patterns after pharmacological or physiological, feeding-related stimuli and was introduced to further understand central regulatory mechanisms of the MCH system. In the first part of work, I wanted to neurochemically characterize MCHR-1 immunoreactive neurons in the rat hypothalamus for colocalisation with neuropeptides of interest. Therefore I performed an immunohistochemical colocalisation study using a specific antibody against MCHR-1 in combination with antibodies against hypothalamic neuropeptides. I showed that MCHR-1 immunoreactivity (IR) was co-localised with orexin A in the lateral hypothalamus, and with adrenocorticotropic hormone and neuropeptide Y in the arcuate nucleus. Additionally, MCHR-1 IR was co-localised with the neuropeptides vasopressin and oxytocin in magnocellular neurons of the supraoptic and paraventricular hypothalamic nucleus and corticotrophin releasing hormone in the parvocellular division of the paraventricular hypothalamic nucleus. Moreover, for the first time MCHR-1 immunoreactivity was found in both the adenohypophyseal and neurohypophyseal part of the rat pituitary. These results provide the neurochemical basis for previously described potential physiological actions of MCH at its target receptor. In particular, the MCHR-1 may be involved not only in food intake regulation, but also in other physiological actions such as fluid regulation, reproduction and stress response, possibly through here examined neuropeptides. Central activation patterns induced by pharmacological or physiological stimulation can be mapped using c-Fos immunohistochemistry. In the first experimental design, central administration (icv) of MCH in the rat brain resulted in acute and significant increase of food and water intake, but this animal treatment did not induce a specific c-Fos induction pattern in hypothalamic nuclei. In contrast, sub-chronic application of MCHR-1 antagonist promoted a significant decrease in food- and water intake during an eight day treatment period. A qualitative analysis of c-Fos immunohistochemistry of sections derived from MCHR-1 antagonist treated animals showed a specific neuronal activation in the paraventricular nucleus, the supraoptic nucleus and the dorsomedial hypothalamus. These results could be substantiated by quantitative evaluation of an automated, software-supported analysis of the c-Fos signal. Additionally, I examined the activation pattern of rats in a restricted feeding schedule (RFS) to identify pathways involved in hunger and satiety. Animals were trained for 9 days to feed during a three hour period. On the last day, food restricted animals was also allowed to feed for the three hours, while food deprived (FD) animals did not receive food. Mapping of neuronal activation showed a clear difference between stareved (FD) and satiated (FR) rats. FD animals showed significant induction of c-Fos in forebrain regions, several hypothalamic nuclei, amygdaloid thalamus and FR animals in the supraoptic nucleus and the paraventricular nucleus of the hypothalamus, and the nucleus of the solitary tract. In the lateral hypothalamus of FD rats, c-Fos IR showed strong colocalisation for Orexin A, but no co-staining for MCH immunoreactivity. However, a large number of c-Fos IR neurons within activated regions of FD and FR animals was co-localised with MCHR-1 within selected regions. To conclude, the experimental set-up of scheduled feeding can be used to induce a specific hunger or satiety activation pattern within the rat brain. My results show a differential activation by hunger signals of MCH neurons and furthermore, demonstrates that MCHR-1 expressing neurons may be essential parts of downstream processing of physiological feeding/hunger stimuli. In the final part of my work, the relevance of here presented studies is discussed with respect to possible introduction of MCHR-1 antagonists as drug candidates for the treatment of obesity.
This paper describes the proof calculus LD for clausal propositional logic, which is a linearized form of the well-known DPLL calculus extended by clause learning. It is motivated by the demand to model how current SAT solvers built on clause learning are working, while abstracting from decision heuristics and implementation details. The calculus is proved sound and terminating. Further, it is shown that both the original DPLL calculus and the conflict-directed backtracking calculus with clause learning, as it is implemented in many current SAT solvers, are complete and proof-confluent instances of the LD calculus.
Intonation and discourse
(2007)
This paper surveys a range of constructions in which prosody affects discourse function and discourse structure.We discuss English tag questions, negative polar questions, and what we call “focus” questions. We postulate that these question types are complex speech acts and outline an analysis in Segmented Discourse Representation Theory (SDRT) to account for the interactions between prosody and discourse.
Die Apartheid in Südafrika war ein Unrechtssystem. Zu den Grausamkeiten des Regimes zählten Massaker, Folter, Mord, Freiheitsberaubung, Zwangsumsiedlung, ökonomische Benachteiligung und alltägliche Diskriminierung. Was nach dem Ende eines solchen Unrechtssystems bleibt, ist die Frage nach dem Umgang mit der Vergangenheit. Die drei grundlegenden Möglichkeiten der Vergangenheitsbewältigung sind die rein justiziare Aufarbeitung, eine Generalamnestie oder ein drittes Modell, das zum Ziel hat, die Vorteile der beiden anderen Strategien zu vereinen. In Südafrika versuchte man, auch als Kompromiss aller Beteiligter, diesen dritten Weg mit der Einrichtung der Wahrheits- und Versöhnungskommission, die mittlerweile weltweit zum Sinnbild dieser Form der Vergangenheitsbewältigung geworden ist. Das Ziel der Studie war dabei zu klären: War die Wahrheits- und Versöhnungskommission in Südafrika als Strategie der Vergangenheitsbewältigung erfolgreich? Im Einzelnen widmete sich die TRC in drei Hauptausschüssen (Menschenrechtsausschuss, Amnestieausschuss und Wiedergutmachungsausschuss) den folgenden Zielen: Aufklärung der Menschenrechtsverletzungen, Klärung des Verbleibs verschwundener Personen, Klärung dessen, was während der Apartheid und der Übergangsphase zerstört wurde um die Verbrechen zu verschleiern, Wiedergutmachung für die Opfer und Amnestierung der Täter bei politisch motivierten Taten. Dieser letzte Punkt war jedoch an die völlige Offenlegung der Tat und ein öffentliches Eingeständnis gebunden. Zum einen zeigt die Analyse die großen Erfolge der Wahrheits- und Versöhnungskommission in Südafrika. Sie hat mehr und vor allem genauere Informationen über die Apartheid zusammengetragen, als je eine andere Untersuchung es geschafft hat. Mit der starken Beteiligung der Bevölkerung am Prozess der Aufklärung konnte sie einen Prozess in Gang bringen, der zur Entstehung einer neuen Menschenrechtskultur beitrug und auch einen Anstoß zur Versöhnung gab. Durch die intensive Aufarbeitung der Vergangenheit in einem gesamtgesellschaftlichen Prozess schaffte es die TRC auch, eine politische Kultur anzuregen, die unentbehrlich ist, will man nach einem Unrechtssystem eine demokratische Zukunft aufbauen. Das Verständnis oder zumindest eine Ahnung von dem was Menschenrechtsverletzungen bedeuten, wurde in dieser Zeit tief im Bewusstsein der meisten Südafrikaner verankert. Es wurde eine „operative Wahrheit“ geschaffen, die, wenn auch unter Protesten aller Parteien, letztlich anerkannt wurde und somit ein zukünftiges Leugnen der Apartheidsverbrechen unmöglich machte. Aber auch die Befreiungsbewegungen mussten brutale Verbrechen eingestehen. Zum anderen wird ebenso deutlich, dass die gestellten Anforderungen bei weitem zu hoch waren. Obwohl große Bereiche der alltäglichen Apartheid komplett unberücksichtigt blieben. Bei der Wahrheitsfindung wurde deutlich, dass die drei Ausschüsse weit von einer wirklichen Aufklärung der Untaten der Apartheid entfernt blieben. Auch in Bezug auf die Täter erreichte die Kommission nur zum Teil ihre Ziele. Verglichen mit den aufgeklärten Verbrechen, beantragte nur ein Bruchteil der Täter Amnestie. Die Logik, durch den Anreiz der Straffreiheit eine rege Beteiligung der Täter am Aufklärungsprozess zu erreichen, ging nicht auf. Bei der Wiedergutmachung zeigte sich, dass es einer der größten Konstruktionsfehler der TRC war, die Umsetzung der Entschädigungen dem Parlament und der Regierung zu überlassen. Der Wiedergutmachungsausschuss erarbeitete lediglich Vorschläge an den Präsidenten. Die wurden jedoch nie in dieser Form umgesetzt und stellten damit die TRC als Ganze bei Teilen der schwarzen und farbigen Bevölkerung in Frage. Einen direkten Zusammenhang zwischen der TRC und einer Befriedung der Bevölkerung herzustellen, wäre vermessen. Noch immer ist Südafrika ein gespaltenes Land. Ähnliches gilt bei der Legitimierung und Konsolidierung der neuen demokratischen Ordnung. Auch hier ist die Kommission ein Baustein, auf den nicht verzichtet werden konnte. Ihr diesen Erfolg, und es ist ein Erfolg im heutigen Südafrika, alleine zuzuschreiben, wäre eine extreme Überschätzung ihrer Möglichkeiten. Unterm Strich bleibt: Die TRC konnte nicht all ihre Ziele erreichen, aber sie hat sich gerade unter den Voraussetzungen des Übergangsprozesses als eine sinnvolle Form der Vergangenheitsbewältigung erwiesen, die grundlegend wichtige Ergebnisse erarbeiten konnte. Sie kann somit trotz der Berücksichtigung einer Vielzahl von Problemen als Erfolg gewertet werden.
Reichsführer-SS Heinrich Himmler maß körperlicher Ertüchtigung und sportlichem Wettbewerb einen hohen Stellenwert zu. Die Angehörigen der SS waren verpflichtet, das SA-Sportabzeichen zu erwerben, um - gemäß der nationalsozialistischen Weltanschauung - eine natürliche Auslese zu erzielen und die Formierung einer elitären Truppe sicherzustellen. Während des "SS-Sportjahres" fanden paramilitärische Übungen statt, in denen sich die Schutzstaffeln auf deutschlandweite Wettbewerbe gegen andere NS-Organisationen vorbereiteten. Doch klafften Anspruch und Realität häufig weit auseinander. Die "Schwarzen Reiter" erwiesen sich hingegen als sportlich äußerst erfolgreich - die Hauptreitschule München versuchte am Vorabend des Zweiten Weltkrieges der Einberufung zu entgehen mit dem Hinweis, dass man sich auf die Olympischen Spiele von 1940 vorbereiten müsse.
Seit vier Jahrzehnten werden verschiedene Neurofeedbackmethoden bei der Behandlung unterschiedlicher Störungen, unter anderem bei AD/HS-Kindern, eingesetzt. Die Grundlage der Anwendung von Neurofeedback bei dieser Störung besteht darin, dass die Kinder Auffälligkeiten in ihrem EEG zeigen. Dort treten im Vergleich zu unauffälligen Kindern vermehrt Theta-Gehirnwellen und weniger Beta-Gehirnwellen auf. Mittels Neurofeedback wird versucht, die Gehirnfunktionen zu korrigieren. Zahlreiche Einzellfallstudien bestätigen die Wirksamkeit dieser Therapiemethode bei der AD/HS-Behandlung. Bisher wurde jedoch keine Studie veröffentlicht, in der die Wirksamkeit von Neurofeedback mit einer Placebogruppe verglichen wurde. Ziel der vorliegenden Studie war es, die Wirksamkeit eines Theta/Beta-Neurofeedbacks (NF) bei der Behandlung von AD/HS-Kindern zu überprüfen und mit einem EMG-Biofeedback (BF) als Placebobedingung zu vergleichen. Es wurden 35 ADHS-Kinder (6 -14 Jahre; 26 Jungen und 9 Mädchen) untersucht. Nach Standarddiagnostik und Vergabe der AD/HS-Diagnose durch einen unabhängigen Psychotherapeuten wurden die Kinder per Zufall zwei Gruppen (NF: n = 18 bzw. BF: n = 17) zugeteilt. Alle Kinder beider Gruppen erhielten ein 30 Sitzungen umfassendes Training mittels Theta/Beta-Neurofeedback bzw. EMG-Biofeedback. Unmittelbar vor und nach dem Training wurden Intelligenz- bzw. Aufmerksamkeitsleistungen untersucht und Einschätzungen des Verhaltens von Eltern und Lehrern erhoben. Im Anschluss an das Training erfolgte eine erneute diagnostische Einschätzung durch einen unabhängigen Psychotherapeuten. Die EEG-Daten in der NF-Gruppe zeigen eine Reduktion der Theta/Beta-Quotienten im Laufe der NF-Sitzungen. Die EMG-Daten zeigen für die EMG-Biofeedback-Bedingung gleichfalls eine Reduktion der EMG-Amplitude. Die Ergebnisse der zweifaktoriellen Varianzanalysen mit Messwiederholung auf einem Faktor zeigen für die angewendeten diagnostischen Verfahren die erwarteten signifikanten Interaktionen zwischen Messzeitpunkt und Gruppe. Die Ergebnisse des t-Tests zeigen signifikante Verbesserungen in der Aufmerksamkeitsleistung, dem Intelligenzniveau und im Verhalten der Kinder aus der NF-Gruppe im Vergleich zu den Resultaten des Prä-Tests. Die EMG-Biofeedbackgruppe zeigt mit Ausnahme einer Erhöhung des Arbeitstempos in den Paper-Pencil-Aufmerksamkeitstests (die im CPT nicht repliziert werden konnte) keine signifikanten Verbesserungen relativ zum Prä-Test. Nach dem Training erhielten 55,6 % (n = 10) der AD/HS-Kinder aus der Neurofeedbackgruppe und 23,5 % (n = 4) der Kinder aus der EMG-Biofeedbackgruppe keine AD/HS-Diagnose nach den Kriterien der ICD-10. Der Chi-Quadrat-Test zeigt jedoch lediglich einen tendenziell bedeutsamen Unterschied (p = .086). Insgesamt bestätigen die Ergebnisse die Wirksamkeit des Neurofeedbacks bei der Behandlung von ADHS-Kindern im Vergleich mit einer Placebogruppe. Weitere Studien in diesem Bereich sind notwendig, um die Wirksamkeit des Neurofeedbacktrainings im Vergleich zu einer Placebomethode bei der ADHS-Behandlung zu untersuchen.

In der Nanotechnologie und der molekularen Biologie werden immer kleinere Strukturelemente, wie beispielsweise einzelne Atomlagen oder Molekülgruppen, manipuliert, um bestimmte Funktionen zu erzielen. Veränderungen in solchen Systemen laufen auf atomarer Längen- und Zeitskala ab. Für das physikalische Verständnis dieser ultraschnellen Prozesse ist ein anschauliches Bild wichtig. Dank ihrer hohen Struktur- und Zeitauflösung liefert die Femtosekunden-Röntgenbeugung Bildsequenzen atomarer Bewegung von Molekülen und Festkörpern und ermöglicht somit Rückschlüsse über die komplexe Wechselwirkung zwischen Elektronen- und Kernbewegungen. Die aktuellen und zukünftigen Möglichkeiten, Atomen bei ihren Bewegungen zuzusehen, diskutiert der Referent an aktuellen Beispielen.

The cytoskeletal motor protein kinesin-1 (conventional kinesin) is the fast carrier for intracellular cargo transport along microtubules. So far most studies aimed at investigating the transport properties of individual motor molecules. However, the transport in cells usually involves the collective work of more than one motor. In the present work, we have studied the movement of beads as artificial loads/organelles pulled by several kinesin-1 motors in vitro. For a wide range of motor coverage of the beads and different bead (cargo) sizes the transport parameters walking distance or run length, velocity and force generation are measured. The results indicate that the transport parameters are influenced by the number of motors carrying the bead. While the transport velocity slightly decreases, an increase in the run length was measured and higher forces are determined, when more motors are involved. The effective number of motors pulling a bead is estimated by measuring the change in the hydrodynamic diameter of kinesin-coated beads using dynamic light scattering. The geometrical constraints imposed by the transport system have been taken into account. Thus, results for beads of different size and motor-surface coverage could be compared. In addition, run length-distributions obtained for the smallest bead size were matched to theoretically calculated distributions. The latter yielded an average number of pulling motors, which is in agreement with the effective motor numbers determined experimentally.
Exploring elections features from a geographical perspective is the focus of this study. Its primary objective is to develop a scientific approach based on geoinformation technology (GIT) that promotes deeper understanding how geographical settings affect the spatial and temporal variations of voting behaviour and election outcomes. For this purpose, the five parliamentary elections (1991-2005) following the political turnaround in 1990 in the South East European reform country Albania have been selected as a case study. Elections, like other social phenomena that do not develop uniformly over a territory, inherit a spatial dimension. Despite of fact that elections have been researched by various scientific disciplines ranging from political science to geography, studies that incorporate their spatial dimension are still limited in number and approaches. Consequently, the methodologies needed to generate an integrated knowledge on many facets that constitute election features are lacking. This study addresses characteristics and interactions of the essential elements involved in an election process. Thus, the baseline of the approach presented here is the exploration of relations between three entities: electorate (political and sociodemographic features), election process (electoral system and code) and place (environment where voters reside). To express this interaction the concept of electoral pattern is introduced. Electoral patterns are defined by the study as the final view of election results, chiefly in tabular and/or map form, generated by the complex interaction of social, economic, juridical, and spatial features of the electorate, which has occurred at a specific time and in a particular geographical location. GIT methods of geoanalysis and geovisualization are used to investigate the characteristics of electoral patterns in their spatial and temporal distribution. Aggregate-level data modelled in map form were used to analyse and visualize the spatial distribution of election patterns components and relations. The spatial dimension of the study is addressed in the following three main relations: One, the relation between place and electorate and its expression through the social, demographic and economic features of the electorate resulting in the profile of the electorate’s context; second, the electorate-election interaction which forms the baseline to explore the perspective of local contextual effects in voting behaviour and election results; third, the relation between geographical location and election outcomes reflecting the implication of determining constituency boundaries on election results. To address the above relations, three types of variables: geo, independent and dependent, have been elaborated and two models have been created. The Data Model, developed in a GIS environment, facilitates structuring of election data in order to perform spatial analysis. The peculiarity of electoral patterns – a multidimensional array that contains information on three variables, stored in data layers of dissimilar spatial units of reference and scales of value measurement – prohibit spatial analysis based on the original source data. To perform a joint spatial analysis it is therefore mandatory to restructure the spatial units of reference while preserving their semantic content. In this operation, all relevant electoral as well as socio-demographic data referenced to different administrative spatial entities are re-referenced to uniform grid cells as virtual spatial units of reference. Depending on the scale of data acquisition and map presentation, a cell width of 0.5 km has been determined. The resulting fine grid forms the basis of subsequent data analyses and correlations. Conversion of the original vector data layers into target raster layers allows for unification of spatial units, at the same time retaining the existing level of detail of the data (variables, uniform distribution over space). This in turn facilitates the integration of the variables studied and the performance of GIS-based spatial analysis. In addition, conversion to raster format makes it possible to assign new values to the original data, which are based on a common scale eliminating existing differences in scale of measurement. Raster format operations of the type described are well-established data analysis techniques in GIT, yet they have rarely been employed to process and analyse electoral data. The Geovisualization Model, developed in a cartographic environment, complements the Data Model. As an analog graphic model it facilitates efficient communication and exploration of geographical information through cartographic visualization. Based on this model, 52 choropleth maps have been generated. They represent the outcome of the GIS-based electoral data analysis. The analog map form allows for in-depth visual analysis and interpretation of the distribution and correlation of the electoral data studied. For researchers, decision makers and a wider public the maps provide easy-to-access information on and promote easy-to-understand insight into the spatial dimension, regional variation and resulting structures of the electoral patterns defined.

Bacteria play a key role in the world's oceans, supporting nutrient remineralisation and mediating carbon transfer. Little is known about annual changes in bacterial concentration, production and metabolism during the extreme seasonal changes in biological productivity in Antarctic waters. We measured rates of bacterial production, concentrations of viruses and bacteria and environmental parameters between February 2004 and January 2005 at an Antarctic coastal site. Concentrations of total bacteria and viruses were obtained using 4', 6-diamidino-2- phenylindole (DAPI) and SYBR Green I (Molecular Probes), respectively. Populations of bacteria in different metabolic states were estimated using vital stains. Concentrations of bacteria with intact or compromised plasma membranes were estimated using BacLight (Molecular Probes) and active cells estimated using 6-carboxyfluorescein diacetate (6CFDA). Our study showed 6CFDA and BacLight gave rapid and ecologically valuable insights into bacterial physiology, production and growth in natural Antarctic communities that were poorly represented by changes in total cell concentrations. Concentrations of total, active and intact bacteria declined rapidly at the end of summer probably owing to viral infection and microheterotrophic grazing. The decline continued over winter, likely owing to substrate limitation, and concentrations only increased after the phytoplankton bloom in spring and summer. Bacterial abundance was positively correlated with particulate organic carbon (POC) and nitrogen (PON), but not dissolved organic carbon (DOC), reflecting the refractory nature of the DOC pool. Only active and intact bacteria were significantly correlated with concentrations of chl a and rates of bacterial production. Furthermore, the obtained rates of [H-3]thymidine uptake suggest that bacterial growth rates can be sustained by the populations identified as intact or by active cells alone.
In ihrer Vorlesung zeigt Sabine Beuermann, unter welchen Bedingungen Kohlendioxid als Reaktionsmedium für die Herstellung von polymeren Materialien genutzt werden kann. Fluides Kohlendioxid ist ein attraktives Reaktionsmedium, da es ungiftig und nicht brennbar ist. Zudem leistet es einen wichtigen Beitrag zur Entwicklung nachhaltiger chemischer Prozesse, da durch den Einsatz von Kohlendioxid die Verwendung von organischen Lösungsmitteln vermieden werden kann.

Sulphur, a macronutrient essential for plant growth, is among the most versatile elements in living organisms. Unfortunately, little is known about regulation of sulphate uptake and assimilation by plants. Identification of sulphate signalling processes will allow to control sulphate acquisition and assimilation and may prove useful in the future to improve sulphur-use efficiency in agriculture. Many of genes involved in sulphate metabolism are regulated on transcriptional level by products of other genes called transcription factors (TF). Several published experiments revealed TF genes that respond to sulphate deprivation, but none of these have been so far been characterized functionally. Thus, we aimed at identifying and characterising transcription factors that control sulphate metabolism in the model plant Arabidopsis thaliana. To achieve that goal we postulated that factors regulating Arabidopsis responses to inorganic sulphate deficiency change their transcriptional levels under sulphur-limited conditions. By comparing TF transcript profiles from plants grown on different sulphate regimes, we identified TF genes that may specifically induce or repress changes in expression of genes that allow plants to adapt to changes in sulphate availability. Candidate genes obtained from this screening were tested by reverse genetics approaches. Transgenic plants constitutively overproducing selected TF genes and mutant plants, lacking functional selected TF genes (knock out), were used. By comparing metabolite and transcript profiles from transgenic and wild type plants we aimed at confirming the role of selected AP2 TF candidate genes in plant adaptation to sulphur unavailability. After preliminary characterisation of WRKY24 and MYB93 TF genes, we postulate that these factors are involved in a complex multifactorial regulatory network, in which WRKY24 and MYB93 would act as superior factors regulating other transcription factors directly involved in the regulation of S-metabolism genes. Results obtained for plants overproducing TOE1 and TOE2 TF genes suggests that these factors may be involved in a mechanism, which is promoting synthesis of an essential amino acid, methionine, over synthesis of another amino acid, cysteine. Thus, TOE1 and TOE2 genes might be a part of transcriptional regulation of methionine synthesis. Approaches creating genetically manipulated plants may produce plant phenotypes of immediate biotechnological interest, such as plants with increased sulphate or sulphate-containing amino acid content, or better adapted to the sulphate unavailability.
Durante su expedición a América Latina, A. v. Humboldt tuvo numerosos ayudantes indios que le prestaron servicios indispensables, entre otros, como porteadores, remeros, guías de montaña e intérpretes. Sólo conocemos a unos pocos de esos acompañantes por sus nombres: uno de ellos es Carlos del Pino, que acompañó al grupo de viajeros durante dieciséis meses. Los conocimientos lingüísticos de Zerepe resultaron extremadamente útiles a los exploradores durante la travesía del Orinoco. Felipe Aldas compartió con Humboldt los peligros de la ascensión a los Andes. Un indio o mulato le acompañó incluso en su travesía a Europa. Los indicios señalan que se trataba de José de la Cruz, mencionado varias veces en los diarios de viaje. Humboldt sabía que tenía que agradecer a sus compañeros el feliz desenlace de su célebre viaje.

We explored the extent of interspecific hybridisation between alien and native plant species in Germany with a special focus on the potential threat for native biodiversity. In total we listed 134 hybrids which are interpreted as products of hybridisation between 81 alien and 109 native plant species (including 13 archeophytes) that occur in Germany Seventy-five of these hybrids have been recorded in Germany, while the remaining 59 hybrids have not been detected in Germany yet, although both parental species currently occur in Germany. Interspecific hybridisation between abundant alien and rare native species can threaten populations of the native species through outbreeding depression and/ or through high rates of gene flow swamping native populations. We identified 37 threatened native plant species which hybridise with aliens. Seventeen of these threatened plant species may suffer from outbreeding depression when hybridising with a more abundant alien invader (minority disadvantage). Using hybrid abundance as an indicator of hybrid fitness we argue that introgression of alien genes may affect the gene pool of eight threatened native plant species. Consequently, hybridisation with aliens has to be considered as an additional risk potentially leading to a loss of biodiversity and should be included in the repertoire of causes for rare species extinction in German Red Lists of threatened plant species.
The acinar salivary gland of the cockroach, Periplaneta americana, is innervated by dopaminergic and serotonergic nerve fibers. Stimulation of the glands by serotonin (5-hydroxytryptamine, 5-HT) results in the production of a protein-rich saliva, whereas stimulation by dopamine results in saliva that is protein-free. Thus, dopamine acts selectively on ion-transporting peripheral cells within the acini, and 5-HT acts on protein-producing central cells. We have investigated the pharmacology of the 5-HT-induced secretory activity of isolated salivary glands of P. americana by testing several 5-HT receptor agonists and antagonists. The effects of 5-HT can be mimicked by the non-selective 5-HT receptor agonist 5-methoxytryptamine. All tested agonists that display at least some receptor subtype specificity in mammals, i.e., 5-carboxamidotryptamine, (+/-)-8-OH-DPAT, (+/-)-DOI, and AS 19, were ineffective in stimulating salivary secretion. 5-HT-induced secretion can be blocked by the vertebrate 5-HT receptor antagonists methiothepin, cyproheptadine, and mianserin. Our pharmacological data indicate that the pharmacology of arthropod 5-HT receptors is remarkably different from that of their vertebrate counterparts. (C) 2007 Elsevier Ltd. All rights reserved.
Interaction between CRHR1 gene and stressful life events predicts adolescent heavy alcohol use
(2007)
Background: Recent animal research suggests that alterations in the corticotropin releasing hormone receptor 1 (CRHR1) may lead to heavy alcohol use following repeated stress. The aim of this study was to examine interactions between two haplotype-tagging single nucleotide polymorphisms (SNPs) covering the CRHR1 gene and adverse life events on heavy drinking in adolescents. Methods: Data were available from the Mannheim Study of Children at Risk, an ongoing cohort study of the long-term outcome of early risk factors followed since birth. At age 15 years, 280 participants (135 males, 145 females) completed a self-report questionnaire measuring alcohol use and were genotyped for two SNPs (rs242938, rs1876831) of CRHR1. Assessment of negative life events over the past three years was obtained by a standardized interview with the parents. Results: Adolescents homozygous for the C allele of rs1876831 drank higher maximum amounts of alcohol per occasion and had greater lifetime rates of heavy drinking in relation to negative life events than individuals carrying the T allele. No gene X environment interactions were found for regular drinking and between rs242938 and stressful life events. Conclusions: These findings provide first evidence in humans that the CRHR1 gene interacts with exposure to stressful life events to predict heavy alcohol use in adolescents.
