On a practical realization of Kolb's experiential learning cycle

This study aims to extend prior knowledge on the learning and developmental outcomes of the experiential learning cycle of David Kolb by the analysis of its practical realization at Team Academy. The study is based on the constructivist approach to learning and considers, among others, the concepts of autonomy support, Nonaka and Takeuchi's knowledge creation model, Luft and Ingham's Johari Window and Deci and Ryan's Self-determination theory. For the investigation deep interviews were carried out with the participants of Team Academy, both learners and coaches. Taking the interview results and the above described theories into consideration this study concludes that experiential learning results not only in effective learning, but also in a remarkable soft skill acquisition, self-development and increase in motivation with an internal locus of causality. Real-life projects permit the learners to experience real challenges. By the practical activities and teamwork they also get the possibility to find out their personal strengths, weaknesses and unique capacities.

À la mesure du Dasein : la genèse des existentiaux dans la vie animale chez Heidegger (1919-1927)

Nous nous pencherons sur les travaux du jeune Heidegger afin de montrer que, s’il affirme dans Être et temps que les animaux ne sont ni chose, ni Dasein, mais participent d’un énigmatique mode d’être propre – le « simplement vivant », ce qui ne fait « rien de plus que vivre » – cela constitue un revirement dans la pensée heideggérienne. Dans les travaux qui préparent la rédaction de Sein und Zeit, l'animal avait toujours été considéré comme un être qui a un monde, comme un être auquel nous devons reconnaître le mode d'être du Dasein. En s’appuyant sur l’interprétation phénoménologique d’Aristote qu’il présente dans ses cours de 1919 à 1926, nous montrerons que les structures fondamentales de l'être-au-monde ont été élaborées sur le fond des capacités propres à la vie animale que sont l’affection (pathos), la perception (aisthēsis), la discrimination (krinein), la mobilité (kinesis kata topon) et le désir (orexis).

On the dependence of boundary-layer ventilation on frontal type

Case study simulations with idealized tracers have been used to determine the relationship between the dynamics and conceptual representations of different midlatitude frontal systems and the amount, distribution, and time scale of boundary layer ventilation by these systems. The key features of ventilation by a kata– and ana–cold frontal system are found to be quantitatively and also often qualitatively similar to the main ventilation pathways, which are the conveyor belts, cloud head, and other convection. The conveyor belts and cloud head occur within cloud, implying that they can be identified using satellite imagery. Differences in the transport by the two systems can be related to their conceptual representations and include a sensitive dependence on the diurnal cycle for the kata- but not the ana-cold frontal case.

Mapping the BDA20 Gene to BTAX

The lipocalin family is a large group of proteins that exhibits great structural and functional variation both within and among species, including a significant number of animal-derived aeroallergens, such as the bovine BDA20 (major cow dander allergen). This protein is classified as an occupational allergen causing asthma and other work-related allergic disorders among dairy farmers. Using a somatic cell panel the BDA20 gene was assigned to the bovine X chromosome (BTAX) with a significant concordant value of 97% to the previously mapped reference marker MAF45. A radiation hybrid (RH) mapping approach confirmed the assignment of BDA20 to BTAX. Two-point LOD scores showed that BDA20 is linked to XBM451 with a LOD score of 22.1 for a 0 value of 0.03.

Clarifications on breakpoints in HSAX and BTAX by comparative mapping of F9, HPRT, and XIST in cattle

The coagulation factor IX gene (179), the hypoxanthine phosphoribosyl transferase 1 gene (HPRT1), and the X-inactive specific transcript gene (XIST) were physically assigned in cattle to analyze chromosomal breakpoints on BTAX recently identified by radiation hybrid (RH) mapping experiments. Whereas the FISH assignment of XIST indicates a similar location on the q-arm of the human and cattle X chromosomes, the locus of HPRT1 supported the assumption of a chromosome rearrangement between the distal half of the q-arm of HSAX and the p-arm of BTAX identified by RH mapping. F9 previously located on the Cl-arm of BTAX was assigned to the p-arm of BTAX using RH mapping and FISH. The suggested new position of F9 close to HPRT I supports the homology between HSAXq and BTAXp. The F9 locus corresponds with the gene order found in the homologous human chromosome segment. XIST was assigned on BTAXq23, HPRT1 and F9 were mapped to BTAXp22, and the verification of the location of F9 in a 5000 rad cattle-hamster whole genome radiation hybrid panel linked the gene to markers URB10 and HPRT1.

RH maps of bovine chromosomes 15 and 29: conservation of human chromosomes 11 and 5

Comparative mapping data on evolutionary conserved coding sequences and synteny maps between human and cattle are insufficient to define the extent and distribution of conserved segments between these two species, because the order of loci is often rearranged. A 5000-rad cattle whole-genome radiation hybrid (WG-RH) panel was constructed to provide high-resolution comparative maps and also to integrate linkage maps of microsatellites with evolutionary conserved genes and transcripts in a single ordered map. We used the WG-RH panel to construct radiation hybrid maps of bovine Chromosomes (Chrs) 15 and 29 (BTA15 and BTA29), integrating microsatellites from published linkage maps with selected genes. The comprehensive map of BTA15 consists of 24 markers. 13 of which were placed in the framework map. Eleven molecular markers compose the comprehensive map of BTA29. seven of which were placed in the framework map. We identified the homologous regions between bovine Chr 15 (BTA15) and human Chrs 5 and 11 (HSA5 and HSA11), as well as between BTA29 and HSA11, the present study demonstrates that WG-RH mapping is an efficient method for integrating multiple genetic maps into one map and for incorporating monomorphic Type I loci into ordered maps for comparison between species.

A radiation hybrid map of bovine X Chromosome (BTAX)

We present a comprehensive radiation hybrid map of the bovine X chromosome (Chr) containing 20 new markers, including both microsatellites and expressed genes. This study was conducted with a 5000-rad whole genome RH cell panel consisting of 90 hybrid cell lines. Retention frequencies of individual markers range from 7.8% for XIST to 31.1% for TGLA325. Statistical analysis with RHMAPPER placed all the loci into five linkage groups under a LOD score criterion of 6.0. These groups could be oriented relative to each other because they included multiple microsatellite loci from the consensus linkage map of the X Chr. Markers included in both this RH map and the bovine cytogenetic map were in a consistent order. The comparative bovine-human map thus generated consists of five blocks of genes, the order of which is conserved, although in the opposite direction when presented as ideograms with p and q arms. Inversions of three blocks account for the difference in gene order across the entirety of the two X Chrs.

Duktile Gesteinsdeformation durch zeitabhängige Kataklase

In Gesteinen, die bei schwach- bis mittelgradiger Metamorphose deformiert wurden, sind Mikrostrukturen, wie z.B. undulöse Auslöschung, Subkörner und kristallographische Regelungen, typisch. Sie werden i.a. als das Resultat eines kristallplastischen Deformationsprozesses interpretiert. Das häufige Auftreten dieser Strukturen führte zu der Annahme, daß kristallplastische Deformationsprozesse zu den dominierenden duktilen Deformationsmechanismen während der Erdkrustendeformation gehören.Die vorliegende Arbeit beschäftigt sich mit Experimenten, bei denen die zeitabhängige kata-klastische Deformation polykristalliner, kompaktierter Aggregatproben des sehr gut löslichen, elastisch/spröden Salzes Natriumchlorat (NaClO3) untersucht wurde. Dieses Salz wurde als Analogmaterial gesteinsbildender Minerale wie Quarz und Feldspat ausgewählt. Es wurde nun untersucht, ob und in welcher Weise spröde Deformationsmechanismen in Anwesenheit von Wasser scheinbar kristall-plastische Mikrostrukturen hervorrufen können.Aus den Versuchen ergibt sich nun die Folgerung, daß scheinbar kristallplastisch erzeugte Mikrostrukturen wie Subkörner auch durch spröde zeitunabhängige Risse und subkritische (langsame) Kataklase entstehen können. Diese Erkenntnisse sind wichtig für das rheologische Verhalten der Erdkruste und somit auch für Modellierungen der Erdkrustendeformation. Ihre Betrachtung und Übertragung auf die Deformationsstrukturen der natürlich deformierten kontinentalen, oberkrustalen Gesteine der Erde würde die Interpretation der Mikrostrukturen in diesen Bereichen stark ändern. Dies hätte eine wesentliche Änderung auf den Verlauf der Gesteinsfestigkeitskurven in den Spannungsprofilen der Erdoberkruste zur Folge.

Pulmonary edema at recovery after colic operation with in-situ nasogastric tube in a horse

After an uneventful general anesthesia, in a horse negative pressure pulmonary edema developed due to acute upper airway obstruction during the anesthetic recovery phase after colic surgery. No pathologic alteration of respiration was observed until the horse stood up and began suffocating. The horse had recovered with the nasogastric tube in situ. This, together with the postmortem diagnosis of laryngeal hemiplegia resulted in impairment of airflow through the larynx and development of pulmonary edema. Our objective is to alert clinicians about the possible hazard of recovery with an in-situ nasogastric tube.
