Eine exemplarische Betrachtung des Einflusses von Genotyp und Fütterung auf Mastleistung, Schlachtkörperqualität und Fleischqualität in der ökologischen Schweinemast

In der ökologischen Schweinemast bestimmt das Vermarktungsziel die Auswahl der Genetik und Fütterungsintensität. Eine vornehmlich schlachtkörperqualitäts-orientierte Vermarktung, d. h. die Ausrichtung auf Fleischertrag, verlangt moderne Genotypen mit hoher körpereigener Proteinsynthesekapazität (also z. B. eher geringe Duroc-Genanteile im Masttier) und Rationen, die eine qualitativ hochwertige Aminosäurenversorgung gewährleisten, was zu einem mehr oder weniger hohen Nährstoffimport von außen in das landwirtschaftliche System hinein führt (high external input system). Fleischqualitäts-orientierte Vermarktungsziele tolerieren Genotypen mit niedrigerer körpereigener Proteinsynthesekapazität bzw. Rationen mit geringwertigerem Aminosäurenprofil bis hin zu Rationen vollständig betriebseigener Herkunft, woraus ein low external input system resultiert

Bildung und Lebensplanung im ländlichen Raum

Bildung ist Dreh- und Angelpunkt einer aktiven Lebensplanung. Der Bildungsgrad der Menschen einer Region ist unmittelbar mit der Entwicklungsfähigkeit des einzelnen Menschen und der Region insgesamt verbunden: Qualitativ hochwertige Bildung wirkt positiv in alle Lebensbereiche, denn sie ermöglicht ein Handeln nach dem Subsidiaritätsprinzip, ist Kulturgut und Wirtschaftsfaktor. Mangelnde Bildung hingegen verschärft nahezu alle mit dem demografischen Wandel einhergehenden Problembereiche einer Region. […]Wenn auch im ländlichen Raum qualitativ hochwertige und finanziell erschwingliche Bildungsangebote bestehen, wächst die Attraktivität dieser Region für die Menschen, die derzeit (noch) abwandern. […] Die allgemeine Bildungsplanung und auch die individuelle Lebensplanung dürfen sich nicht am Mangel (Finanzen, Bevölkerung usw.) orientieren, sondern müssen anhand positiver realistischer Perspektiven gestaltet werden.

2D cross-hole MMR - survey design and sensitivity analysis for cross-hole applications of the magnetometric resistivity method

The magnetometric resistivity (MMR) method measures low-level (typically < 1nT) magnetic fields associated with a low-frequency (1 - 20 Hz) electric current impressed into the ground to determine the subsurface resistivity structure. As a step towards the implementation of MMR for cross-hole imaging, in this Ph.D. thesis several aspects of survey design for near-surface applications are discussed. In numerical, laboratory and field studies the potential of MMR for advanced structural characterization and process monitoring at the field scale is assessed. The 2D cross-hole setup considers borehole measurements of the magnetic field as response to borehole current injection; in this case the magnetic field has only one non-zero component (perpendicular to the imaging plane – B$_{y}$). Optimal survey parameters are inferred from numerical studies regarding signal strength, source-generated noise level and resolving power. Modeling of MMR responses over 2D conductivity structures was performed using a newly developed 2.5D FE program MMRMod. It could be proven that current injection via vertical dipoles provides superior signal-to-noise ratio compared to other transmitter configurations. Analyzing resolving power in terms of sensitivity distribution reveals that dipole configurations reflect confined subsurface volumes, advantageous for tomographic surveys and that transmitter-receiver combinations exceeding an offset equal to the borehole separation do not contribute significantly to the overall crosshole resolution. With the assistance of laboratory testing two concepts for solving two major difficulties inherent in cross-hole MMR field surveying are derived: the correction for the arbitrary borehole sensor orientation and the correction for parasitic correlated noise fields induced by the measurement system itself. The (latter) measurement method with phase switching is thereby first-time successfully applied to the processing of MMR data. In addition, the proposed data processing procedure includes modern lock-in-technique and has proven to be an appropriate tool for an effective information extraction from the measured magnetic fields. Finally, cross-hole MMR data were collected during a water infiltration experiment at the Gorgonzola test site. Acquisition and processing are accomplished according to the developed tomographic measurement approach involving multiple-offset transmitter-receiver arrangements and repeated measurements with time (time-lapse mode). Data, obtained during initially conducted background measurement, are qualitatively validated based on two different conductivity models, one of which is obtained from the inversion of independently collected ERT data. Importantly, the comparison of field data with predicted model curves suggests better resolvability of contrasts by MMR than by ERT. Moreover, the analysis of time-lapse measurements reveals a clear spatiotemporal dependence of the anomalous MMRresponse (MMR response with respect to background value) based upon the water saturation

Evaluation der Qualität der Promotionskollegs der Hans-Böckler-Stiftung: Eine quantitative und qualitative Studie

In diesem Bericht werden die Ergebnisse eines Projektes referiert, das aus einer qualitativen und einer quantitativen Teilstudie besteht. Ziel des Projektes war es, unterschiedliche Aspekte der Qualität der von der Hans-Böckler-Stiftung im vergangenen Jahrzehnt an verschiedenen deutschen Universitäten eingerichteten Promotionskollegs zu untersuchen. Die gemeinsame Entwicklung der Forschungsinstrumente, regelmäßiger Austausch zwischen den qualitativ und quantitativ forschenden Evaluationsteams und schließlich der Versuch, anhand ausgewählter qualitativ generierter Thesen statistische Zusammenhangsanalysen zu erstellen, zeigt, dass es sich bei dieser Evaluationsstudie nicht um eine schlichte Addition zweier unterschiedlicher Forschungslogiken handelt.Auf Grundlage der Befunde werden Empfehlungen für die weitere Gestaltung der HBS-Kollegs formuliert, die nicht nur für deren Qualitätsentwicklung nützlich sein dürften. Die datengestützten Vorschläge können auch Grundlage für Diskussion über die zukünftige Weiterentwicklung des Kolleg-Modells sein

Die Verrechtlichung von Arbeitsbeziehungen in Joint Ventures und ausländischen Tochterunternehmen in der Volksrepublik China: Ein Zwischenbericht

Up to now, very little is known about human resource policies in Sino-foreign joint ventures and foreign subsidiaries in China. It is, therefore, the aim of this project to study variations in personnel strategies in order to find an economically reasonable explanation for the differing personnel policies. In view of the increasing significance of labour relations law in China, another aim of this project is to examine the relevance of labour regulations in companies with foreign equity participation: When do those concerned rely on legal methods and to what degree are they successful? As only very few studies currently exist, the necessity for collecting our own sample soon became evident. Since not only quantitative, but also qualitative data is required, the case study approach suggests itself as an appropriate starting point. In October 1998 eleven companies in Shanghai were interviewed. This will then be followed up by case studies in two other regions of China in the summer of 1999. The case studies in Shanghai revealed some evidence for the hypothesised dependence of the personnel policy on the product market strategy of the company: The effective use of the redundant cheap labour force in China requires that the firm employs relatively labour intensive production lines. As long as labour laws are not violated, the prices of products manufactured in Shanghai will however often be undercut by Chinese competitors from other regions. Therefore, profits from mass-produced goods can mainly be realised in the export business. In contrast to price-based competition, firms with a differentiation or niche strategy compete on some other dimension that is valued by the market (e.g. product quality, reliability, delivery, service). Whether the company is successful with this strategy depends a lot on its capabilities to implement effective policies to retain qualified employees. Therefore, a differentiation strategy cushions the impact of external market forces more than a mass-production strategy, which tends to be a primarily market-oriented personnel policy. --
