Bildungszielplanung in der Arbeitsförderung: Struktur und Funktion im Land Bremen

In der gegenwärtigen politischen Debatte über den aktuellen wie auch zukünftigen Fachkräftebedarf sowie die Beschäftigungsperspektiven für Arbeitsuchende wird der Weiterbildungsförderung durch die regionalen Arbeitsagenturen und der Jobcenter eine große Bedeutung beigemessen. Arbeitsagenturen und Jobcentern steht hierzu in erster Linie das arbeitsmarktpolitische Instrument Förderung der beruflichen Weiterbildung (FbW) zur Verfügung, dessen rechtliche und organisatorische Rahmenbedingungen sich im Zuge der Umsetzung des Ersten und Zweiten Gesetzes für moderne Dienstleistungen am Arbeitsmarkt (Hartz I-II) fundamental gewandelt haben: So gelten die Einführung von Bildungsgutscheinen und Änderungen im Anerkennungsverfahren von Trägern und Maßnahmen als notwendige Voraussetzungen für mehr Wettbewerb auf dem Markt für Weiterbildung. Darüber hinaus wird der konkrete Bedarf an Bildungsgutscheinen seitdem über eine Bildungszielplanung bestimmt. Mit diesem Planungsinstrument legen die lokalen Arbeitsagenturen und Grundsicherungsträger zum einen dar, welche Weiterbildungsförderung aus arbeitsmarktpolitischer Sicht erforderlich ist und mit welchen Schwerpunkten (Kontingent an Gutscheinen je Bildungssegment/Bildungsziel) sie ihr jeweiliges Mittelbudget umsetzen wollen. Zum anderen richtet sich die Bildungszielplanung an die einzelnen Bildungsträger, welche eine zeitnahe Einlösung der Bildungsgutscheine für die nach dem SGB III notwendigen Qualifizierungskapazitäten gewährleisten sollen..

Metabolomics of fecal samples: a practical consideration

Background Metabolic profiling is becoming increasingly popular to identify subtle metabolic variations induced by diet alterations and to characterize the metabolic impact of variations of the gut microbiota. In this context, fecal samples, that contain unabsorbed metabolites, offer a direct access to the outcome of diet - gut microbiota metabolic interactions. Hence, they are a useful addition to measure the ensemble of endogenous and microbial metabolites, also referred to as the hyperbolome. Scope and Approach Many reviews have focused on the metabolomics analysis of urine, plasma and tissue biopsies; yet the analysis of fecal samples presents some challenges that have received little attention. We propose here a short review of current practices and some practical considerations when analyzing fecal material using metabolic profiling of small polar molecules and lipidomics. Key Findings and Conclusions: To allow for a complete coverage of the fecal metabolome, it is recommended to use a combination of analytical techniques that will measure both hydrophilic and hydrophobic metabolites. A clear set of guidelines to collect, prepare and analyse fecal material is urgently needed

Towards a common description of liquid-state and solid-state cases

Chemically Induced Dynamic Nuclear Polarization (CIDNP) is an efficient method of creating non-equilibrium polarization of nuclear spins by using chemical reactions, which have radical pairs as intermediates. The CIDNP effect originates from (i) electron spin-selective recombination of radical pairs and (ii) the dependence of the inter-system crossing rate in radical pairs on the state of magnetic nuclei. The CIDNP effect can be investigated by using Nuclear Magnetic Resonance(NMR) methods. The gain from CIDNP is then two-fold: it allows one to obtain considerable amplification of NMR signals; in addition, it provides a very useful tool for investigating elusive radicals and radical pairs. While the mechanisms of the CIDNP effect in liquids are well established and understood, detailed analysis of solid-state CIDNP mechanisms still remains challenging; likewise a common theoretical frame for the description of CIDNP in both solids and liquids is missing. Difficulties in understanding the spin dynamics that lead to the CIDNP effect in the solid- state case are caused by the anisotropy of spin interactions, which increase the complexity of spin evolution. In this work, we propose to analyze CIDNP in terms of level crossing phenomena, namely, to attribute features in the CIDNP magnetic field dependence to Level Crossings (LCs) and Level Anti-Crossings (LACs) in a radical pair. This approach allows one to describe liquid-state CIDNP; the same holds for the solid-state case where anisotropic interactions play a significant role in CIDNP formation. In solids, features arise predominantly from LACs, since in most cases anisotropic couplings result in perturbations, which turn LCs into LACs. We have interpreted the CIDNP mechanisms in terms of the LC/LAC concept. This consideration allows one to find analytical expressions for a wide magnetic field range, where several different mechanisms are operative; furthermore, the LAC description gives a way to determine CIDNP sign rules. Thus, LCs/LACs provide a consistent description of CIDNP in both liquids and solids with the prospect of exploiting it for the analysis of short-lived radicals and for optimizing the polarization level

Magnetic field and orientation dependence of solid-state CIDNP

The magnetic field dependence of Chemically Induced Dynamic Nuclear Polarization (CIDNP) in solid-state systems is analyzed theoretically with the aim to explain the puzzling sign change of polarization found at low fields [D. Gräsing et al., Sci. Rep. 7, 12111 (2017)]. We exploit the analysis of polarization in terms of level crossings and level anti-crossings trying to identify the positions of features in the CIDNP field dependence with specific crossings between spin energy levels of the radical pair. Theoretical treatment of solid-state CIDNP reveals a strong orientation dependence of polarization due to the spin dynamics conditioned by anisotropic spin interactions. Specifically, different anisotropic CIDNP mechanisms become active at different magnetic fields and different molecular orientations. Consequently, the field dependence and orientation dependence of polarization need to be analyzed together in order to rationalize experimental observations. By considering both magnetic field and orientation dependence of CIDNP, we are able to explain the previously measured CIDNP field dependence in photosynthetic reaction centers and to obtain a good qualitative agreement between the experimental observations and theoretical results

Facies types and depositional environments of a morphologically diverse carbonate platform : a case study from the Muschelkalk (Middle Triassic) of Upper Silesia, southern Poland

The detailed sedimentological study of the 150-m-thick Muschelkalk succession, deposited on a small (~200 by 80 km), morphologically diverse Upper Silesian carbonate platform during four major marine-transgressive pulses of the Tethys Ocean, enhanced the understanding of the depositional history, palaeogeography, and facies distribution. A total of thirty-five lithofacies types were identified, described and interpreted in terms of depositional settings. These different lithofacies represent various shallow-marine environments along the platform transect, from peritidal to offshore areas. The vertical and lateral organization of the lithofacies delineated was caused by the interplay of platform morphology, third-order eustasy and the long-term tectonic evolution of the area. Accordingly, the carbonate system studied is a good example of the influence of large-scale processes on the facies architecture of carbonate platforms. In general, all of the four Transgressive Systems Tracts are characterized by similarity in lithofacies composition and vertical succession and by minor lateral change, indicating only limited influence of the three large-scale factors mentioned on lithofacies development and distribution during transgressions. In contrast, each of the four associated Highstand Systems Tracts comprises an individual (unique) lithofacies assemblage displaying substantial regional and local variation, which indicates that the filling of accommodation space during highstands strongly depended on the extrinsic processes

Reefal environments and sedimentary processes of the Anisian Karchowice Beds in Upper Silesia, southern Poland

The Anisian shallow-marine Karchowice Beds of the Upper Silesia represent reefal habitats and circum-reefal environments, where biological-mechanical interactions determine sedimentary processes and facies pattern. The purpose of this study was recognition of the interaction between biological and mechanical controls of carbonate deposition. Such interdependence resulted in considerable lateral variability of thickness and lithological features, observed at a distance of 25 km. The western part of the basin is dominated by proximal facies (reefal facies), whereas the eastern one represents distal facies (fore-reef). Sedimentary succession in the western area is twice as thick than the eastern one. It resulted from different rate of subsidence owing to block tectonics, controlled by reactivated ancestral Silesian-Moravian Fault. Small-scale synsedimentary faults confirm syndepositional tectonic activity in the region. Palaeogeographical position caused that the Upper Silesia was strongly affected by monsoon climate, generating storms. These storms contributed to episodic deposition, prevailing during the sedimentation of Karchowice Beds. However, most of time was represented by prolonged non-deposition periods, recorded as interstratal hiatuses, but also by forming of firmgrounds, micritization and coating of bioclasts or substrate recolonisation by organisms

Sedimentology of the "ore-bearing dolomite" of the Kraków-Silesia region (Middle Triassic, southern Poland)

The depositional history and facies heterogeneity of the epigenetically dolomitized Middle Triassic carbonates of southern Poland are poorly recognized, and existing concepts of fluid circulation entirely overlook the primary lithology as a factor controlling fluid flow. This study reconstructs the consecutive phases of Kraków-Silesia Sub-basin history in the Anisian and highlights their influence on the development of the so-called “ore-bearing dolomite”. Extensive fieldwork and microfacies analyses were carried out in order to decipher the original depositional fabric of the ore-bearing dolomites. As a rule, epigenetic dolomitization affected a horizon of porous strata, 35 m thick and resting directly on impermeable, wavy-nodular clay-rich calcilutites of the Gogolin Formation, which represent the interval of deepest and fully marine (offshore) sedimentation. The sedimentary succession of the porous strata is bipartite. The lower part (Olkusz Beds) is composed of Balanoglossites and Thalassinoides micritic firmgrounds and peloidal packstones-grainstones, representing shoreface-foreshore facies assemblages, whereas the upper part (Diplopora Beds) consists of dolocretes, rhizolites, cryptalgal laminites, peloidal packstones-grainstones and bioturbated fine-grained dolostones, formed in a system of tidal flats and lagoons. These two parts are separated by a subaerial disconformity, which marks a sequence boundary. During emersion, the underlying deposits were subjected to meteoric diagenesis, which led to the development of moldic porosity. This combination of depositional history and diagenetic alteration determined the routes of initial migration of dolomitizing solutions on the one hand, and the location of cavern formation on the other. Owing to progressive dissolution, small caverns were changed into large karstic forms, in which the ore minerals precipitated ultimately. These findings emphasize the importance of sedimentological analysis to the understanding of the evolution of the Kraków-Silesia ore province
