Motive und Motivationen als Grundlage menschlichen Verhaltens – Überlegungen zu einer integrativen Motivationstheorie
No full textDie Untersuchungen der Autorin zur Motivation führen zu dem Schluss, dass Grundmotive im Menschen genetisch angelegt sind. Diese sind implizit in seinem Menschen- und Weltbild vorhanden und werden in situativen Motivationsprozessen aktualisiert. Das Motiv der Hilfeleistung, das in therapeutischen oder beraterischen Prozessen beim Therapeuten aktiviert ist, findet ein Gegenüber im Motiv der Suche nach Hilfe beim Klienten. Beide Seiten folgen einem, von der Autorin dargestellten intersubjektiven Motivationsprozess.The author’s research focuses on the origin and development of motives and moti¬vation with special emphasis on the motive of helpfulness in therapy or consulting. Helpfulness is an essential of the human character. It determines our concepts of the world and of mankind. From an integrative point of view the author discusses the origins of motives in man and develops a structural model of the process of motivation and behaviour of both, client and therapist.https://www.fpi-publikation.de/polyloge/13-2012-jaekel-brigitte-motive-und-motivationen-als-grundlage-menschlichen-verhaltens/peerReviewedpublishedVersio

Multimodal characterization of lignocelluloses in the frame of biofuel production
No full textInternational audienceLignocellulosic biomass bioconversion is hampered by the structural and chemical complexity of the network created by cellulose, hemicellulose and lignin. The conversion of cell wall biomass to sugar for fermentation to ethanol thus requires chemical or physical pretreatments to disrupt the recalcitrant plant cell walls and to make the cellulose accessible to cellulolytic enzymes. Within the frame of a French national project on the production of 2G ethanol, we have developed a multimodal approach to investigate lignocellulose (LC) traits related to enzymatic saccharification. Besides classical wet chemistry characterization, multiscale analysis of LC was implemented using 2D NMR and non-invasive methods, such as fluorescence and infrared spectroscopy. Using representative biomass feedstocks (poplar, miscanthus and wheat straw) which were pretreated at different severity levels during a steam explosion step, we have shown that easily-measured spectral features showed strong correlation with enzymatic saccharification (1-2). Complementary, evaluation of plant cell wall accessibility through a combination of innovating fluorescence microscopy techniques using small probes (FRAP, FRET) brought further insights into the impact of physicochemical pretreatments on LC samples (3-4).1- Auxenfans et al.

Changes in the cell wall network during the thermal dehydration of alfalfa stems
No full textThe effects of heat treatments used to dry alfalfa stems were investigated. Heating at 70 or 100 °C caused no major change in the cell wall composition, but xylanase had lower activity on the cell wall of heated material and the amount of xylose released varied with the temperature used. Chemical fractionation of cell wall carbohydrates showed that the main changes occurring during stem dehydration concerned pectic polymers and probably hemicelluloses. There was less material soluble in ammonium oxalate from alfalfa heated at 100 °C than from fresh alfalfa. The results suggest that heat processing causes some changes in the cell wall network. Environmental scanning electron microscopy was used to examine fully hydrated tissues at high resolution. There was cell distortion without disruption of cell walls as water was lost

Exploring accessibility of pretreated poplar cell walls by measuring dynamics of fluorescent probes
No full textBackground: The lignocellulosic cell wall network is resistant to enzymatic degradation due to the complex chemical and structural features. Pretreatments are thus commonly used to overcome natural recalcitrance of lignocellulose. Characterization of their impact on architecture requires combinatory approaches. However, the accessibility of the lignocellulosic cell walls still needs further insights to provide relevant information. Results: Poplar specimens were pretreated using different conditions. Chemical, spectral, microscopic and immunolabeling analysis revealed that poplar cell walls were more altered by sodium chlorite-acetic acid and hydrothermal pretreatments but weakly modified by soaking in aqueous ammonium. In order to evaluate the accessibility of the pretreated poplar samples, two fluorescent probes (rhodamine B-isothiocyanate-dextrans of 20 and 70 kDa) were selected, and their mobility was measured by using the fluorescence recovery after photobleaching (FRAP) technique in a full factorial experiment. The mobility of the probes was dependent on the pretreatment type, the cell wall localization (secondary cell wall and cell corner middle lamella) and the probe size. Overall, combinatory analysis of pretreated poplar samples showed that even the partial removal of hemicellulose contributed to facilitate the accessibility to the fluorescent probes. On the contrary, nearly complete removal of lignin was detrimental to accessibility due to the possible cellulose-hemicellulose collapse. Conclusions: Evaluation of plant cell wall accessibility through FRAP measurement brings further insights into the impact of physicochemical pretreatments on lignocellulosic samples in combination with chemical and histochemical analysis. This technique thus represents a relevant approach to better understand the effect of pretreatments on lignocellulose architecture, while considering different limitations as non-specific interactions and enzyme efficiency

Recenzja: Wiedeński okres w życiu Adolfa Hitlera w ujęciu Brigitte Hamann i Augusta Kubizka
No full text THE VIENNESE PERIOD IN ADOLF HITLER’S LIFE AS PRESENTED BY BRIGITTE HAMANN AND AUGUST KUBIZEKThe article discusses the literature and the findings concerning the relatively least explored questions concerning Adolf Hitler, namely those of his youth. As the author stresses, just over a dec­ade ago Polish readers interested in the Hitler phenomenon knew much less than they do now. Thanks to several books recently published in Poland they have had a chance to considerably expand their knowledge. The present author points to two figures, Brigitte Hamann and August Kubizek, focusing on the similarities and differences in their approach to this period of Hitler’s life.
