description: Der Berufswahlpass besteht bereits seit ca. zwei Jahrzehnten und hat als papierbasiertes Portfolio-Instrument in der Vergangenheit seinen Weg in viele Curricula der Bundesländer gefunden. In der Schulpraxis wird der Berufswahlpass seither im berufsorientierenden Unterricht und darüber hinaus eingesetzt. Im Zuge der zunehmenden Digitalisierung – insbesondere auch der Lebenswelten von Schüler*innen – stellte sich jedoch in der Vergangenheit immer wieder die Frage, wie das traditionelle Verständnis des Berufswahlpass-Ordners als analoges Portfolio modernisiert werden kann und zukünftig insbesondere die Potenziale digitaler Medien für das Lehren und Lernen in der Beruflichen Orientierung nutzbar gemacht werden können. Diese Vision liegt dem Forschungs- und Entwicklungsprojekt „Berufswahlpass 4.0“ zugrunde, dessen Ziel es ist, ein innovatives, gebrauchswertorientiertes, nachhaltig einsetzbares, wirksames und erprobtes E-Portfolio-Konzept zu gestalten, das in der didaktischen Dimension eine Weiterentwicklung des Berufswahlpasses darstellt und in der technischen Dimension die Potenziale digitaler Medien konsequent und didaktisch begründet berücksichtigt. Damit soll ein Beitrag zur Förderung von Berufswahlkompetenz, zum Einsatz digitaler Medien in der Schule sowie zur E-Portfolio-Arbeit als Mittel zum selbstorganisierten und eigenverantwortlichen Lernen geleistet werden. Im Projekt entsteht als Kernprodukt die so genannte „berufswahlapp“, die perspektivisch als digitales Pendant zum Berufswahlpass-Ordner in der Schulpraxis zum Einsatz kommen wird.

Dieses gilt zweifelsohne für sämtliche potentielle Lernorte: Die Berufsschule, den Betrieb und überbetriebliche Lehrwerkstätten. Nicht nur die Lernorte sind variabel, auch die Lehrpersonen: Berufsschullehrer, Ausbilder (Trainer) und ausbildende Fachkräfte (Mentoren) unterstützen die Kompetenzentwicklung der Auszubildenden. Doch wie ist die Berufliche Bildung in verschiedenen europäischen Ländern (Deutschland, Italien, Litauen, Spanien) organisiert und wie werden die Lernorte genutzt? Berufliche Bildung zeichnet sich besonders durch das Lernen im Prozess der Arbeit aus. Wer lehrt in den teilnehmenden Ländern im Betrieb bzw. in überbetrieblichen Lehrwerkstätten? Und wie werden diese Personen ausgewählt und qualifiziert? Der vorliegende Forschungsbericht beantwortet diese Fragen für die vier genannten Länder und weist mittels nationaler SWOT (Stärken, Schwächen, Chancen, Risiken) Analysen auf Entwicklungsbedarfe hin.

description: The lungfish, the extant sister group of the tetrapods, have an evolutionary history illustrated by a fossil record extending for ∼420 million years. The post-Paleozoic fossil record of the clade is almost exclusively restricted to sediments deposited in freshwater paleoenvironments and is characterized by an abundance of highly mineralized tooth plates, whereas cranial and postcranial remains are scarce. Here, we report a sample of isolated tooth plates found in the Upper Triassic Pebbly Arkose Formation of the Mid-Zambezi Basin, Zimbabwe. It consists of pterygoid and prearticular tooth plates from adult individuals, plus some dental plates referred to juvenile individuals, which we refer to a new species of Ferganoceratodus. This discovery provides an opportunity to review briefly the tooth plates of the ‘ptychoceratodontid morphotype’ reported from around the world. We discuss how various occurrences previously referred to Ptychoceratodus may be more appropriately referred, with caution, to Ferganoceratodus. We also describe the histology of the tooth plates of the new species and note similarities with other Mesozoic taxa. The scarcity of histological data for Mesozoic lungfish tooth plates compounds the problem of assigning isolated tooth plates to genus and species level. Ferganoceratodus and closely related taxa arose in the Early Triassic in southern Gondwana and diversified worldwide in the Late Triassic. The genus then became more common in Laurasia during the Jurassic and Early Cretaceous and declined thereafter with relict Late Cretaceous occurrences in Madagascar and South America.

description: Fossil snakes of the family Palaeophiidae are primarily known from rare, isolated vertebrae, leading to a poor understanding of the intra- and inter-columnar variation within a palaeophiid species. This leads to ambiguity in the taxonomic identity of these snakes, as in the case of the Eocene-age marine snakes of the genus Pterosphenus, in which the majority of species have been described by characters of problematic taxonomic value. Here, we propose a taxonomic revision of the genus based on an articulated to semi-articulated section of the vertebral column at the anterior to mid trunk-transition of Pterosphenus schucherti discovered from the middle Eocene (Bartonian) Harudi Formation, Kachchh (Kutch) Basin. The characters that separate Pterosphenus schucherti from ‘Pterosphenus schweinfurthi’ and ‘Pterosphenus biswasi,’ viz., the height of the pterapophysis and the anterior concavity of the zygosphene, have been found to be non-diagnostic, and the latter two species have been synonymized with the type species. Additionally, we utilized 2D and 3D landmark-based geometric morphometry to determine the morphometric affinity of palaeophiids amongst the alethinophidian snakes. The body size of the snake was estimated based on extant snakes with a morphometric affinity to Palaeophiidae. The cosmopolitan distribution of Pterosphenus schucherti is modelled based on the sea surface temperature (SST) constraints of the modern cosmopolitan snake Hydrophis platurus, and the known fossil localities of the species. The present findings provide crucial insights into the global paleoecological landscape of the Eocene, and the interactions of Pterosphenus schucherti with other palaeophiid snakes as well as the other Eocene fauna.
Cell Migration is Regulated by Mitochondria and Endoplasmic Reticulum Morphology.

description: Cell migration is essential for homeostasis and the development of metastases. We hypothesize that cell migration is regulated by mitochondria and endoplasmic reticulum morphology. Using live cell microscopy, we found that mitochondria specifically migrate into the biochemically dense leading edge of the cell interacting with focal adhesions as well. At the leading edge the mitochondria are visibly shorter and less tubular than the perinuclear area. This is related to the elevated levels of fission events per minute in the leading edge and elevated levels of fusion events per minute in the trailing edge. We observe that mitochondria migrate along microtubules and simultaneously interact with the ER. When the ER is sheet-like the mitochondria are longer and tubular and when the ER is tubular the mitochondria are shorter and punctate. This change in ER and mitochondria morphology changes the cell’s ability to migrate. CLIMP63 cells have more sporadic turns, take longer to make turns, have shorter distances travelled and shorter displacements. To determine whether mitochondria dynamics play a role we examined these cell migration parameters in the presence of OPA1 and Drp1. This allowed us to conclude that the ER morphology is responsible for the distance and displacement the cell travels while the mitochondria is responsible for the angles the cell turns. When the ER is sheet-like the cells will be travel shorter total distances and displacements and when the cell has longer mitochondria it will be sporadic turns and take longer to make these turns.

description: We present results of deep 153 ks Chandra observations of the hot, 11 keV, galaxy cluster associated with the radio galaxy 3C 438. By mapping the morphology of the hot gas and analyzing its surface brightness and temperature distributions, we demonstrate the presence of a merger bow shock. We identify the presence of two jumps in surface brightness and in density located at $\sim$400 kpc and $\sim$800 kpc from the cluster's core. At the position of the inner jump, we detect a factor of $2.3\pm 0.2$ density jump, while at the location of the outer jump, we detect a density drop of a factor of $3.5 \pm 0.7$. Combining this with the temperature distribution within the cluster, we establish that the pressure of the hot gas is continuous at the 400 kpc jump, while there is a factor of $6.2 \pm 2.8$ pressure discontinuity at 800 kpc jump. From the magnitude of the outer pressure discontinuity, using the Rankine-Hugoniot jump conditions, we determine that the sub-cluster is moving at $M = 2.3\pm 0.5$, or approximately $2600\pm 565$ km/s through the surrounding intracluster medium, creating the conditions for a bow shock. Based on these findings, we conclude that the pressure discontinuity is likely the result of an ongoing major merger between two massive clusters. Since few observations of bow shocks in clusters have been made, this detection can contribute to the study of the dynamics of cluster mergers, which offers insight on how the most massive clusters may have formed.

description: In this paper we extend the familiar continuum electrostatic model with a perturbation to the usual macroscopic boundary condition. The perturbation is based on the mean spherical approximation (MSA), to derive a multiscale hydration-shell boundary condition (HSBC). We show that the HSBC/MSA model reproduces MSA predictions for Born ions in a variety of polar solvents, including both protic and aprotic solvents. Importantly, the HSBC/MSA model predicts not only solvation free energies accurately but also solvation entropies, which standard continuum electrostatic models fail to predict. The HSBC/MSA model depends only on the normal electric field at the dielectric boundary, similar to our recent development of an HSBC model for charge-sign hydration asymmetry, and the reformulation of the MSA as a boundary condition enables its straightforward application to complex molecules such as proteins.

description: A key element of an agenda for farm management in the 21st Century should be productivity on farms. The gains from productivity since 1953 have been enough to offset declines in the real price of farm outputs at least in the broadacre sector. Productivity gains will remain important to the sector in this century. For public institutions, the focus of research and extension activities will continue to switch to the management of natural resources. Farmers and policy makers will need to know the on-farm impacts of technologies and policies that will effect resource stocks over many years. A challenge to farm management professionals will be how to present this information, derived from sophisticated modelling, to farmers and policy makers. My guess is that Malcolm’s ‘few figurings’ of a ‘few futures’ is the way to go.

description: We studied the characteristic physical properties and behavior of broadband microwave sub-second pulsations observed in an expanding coronal loop during the GOES C2.4 solar flare on 2011 August 10. We found sub-second pulsations and other different burst groups in the complex radio spectrum. The broadband (bandwidth about 1 GHz) sub-second pulsations (temporal period range 0.07-1.49 s, no characteristic dominant period) lasted 70 s in the frequency range 4-7 GHz. These pulsations were not correlated at their individual frequencies, had no measurable frequency drift, and zero polarization. In these pulsations, we found the signatures of fast sausage magnetoacoustic waves with the characteristic periods of 0.7 and 2 s. The other radio bursts showed their characteristic frequency drifts in the range of -262-520 MHz/s. They helped us to derive average values of 20-80 G for the coronal magnetic field strength in the place of radio emission. It was revealed that the microwave event belongs to an expanding coronal loop with twisted sub-structures observed in the 131, 94, and 193 A SDO/AIA channels. Their slit-time diagrams were compared with the location of the radio source at 5.7 GHz to realize that the EUV intensity of the expanding loop increased just before the radio source triggering. We reveal two EUV bidirectional flows that are linked with the start time of the loop expansion. Their positions were close to the radio source and propagated with velocities within a range of 30-117 km/s. We demonstrate that periodic regime of the electron acceleration in a model of the quasi-periodic magnetic reconnection might be able to explain physical properties and behavior of the sub-second pulsations. The depolarization process of the microwave emission might be caused by a plasma turbulence in the radio source. Finally, the observed EUV flows might be linked with reconnection outflows.

Before and after the duality, we observe interesting differences between the spectra and interpret them. The spectrum of masses and the interactions among mesonic excitations teach valuable lessons about the character of non-Abelian T-duality and its implications for Holography. The case of Abelian T-duality is also studied.

description: Stroke is a brain injury and the second leading cause of death globally, with most stroke survivors having physical or psychological sequels. Stroke survivors that actively engage with their own rehabilitation process have better recovery and rehabilitation results. Research has explored the use of technology in support of physical and cognitive rehabilitation, such as gamification or robotics. However, despite the growing use of Embodied Conversational Agents to support patients with healthcare management, their use in self-management rehabilitation for stroke survivors has not been reported. This MRes thesis presents results of the iTakeCharge study, which uses the conversational agent TaCIA (Taking Charge Intelligent Agent) to facilitate a narrative based self-management intervention for stroke recovery, inspired by the Taking Charge After Stroke (TaCAS) session. In previous studies, TaCAS has been shown to contribute to significant improvements in quality of life, independence, and reductions in disability health. The iTakeCharge study adapted the TaCAS session module ‘Look(ing) at the big picture’ to be deployed in a digital session by TaCIA, as opposed to a human facilitator. The objective of this research is to evaluate the feasibility of a TaCAS inspired digital session facilitated by a conversational agent in support of stroke survivors. Three pilot studies were conducted with different stakeholders: TaCAS researchers, former TaCAS session facilitators and stroke survivors; each cohort having a session with TaCIA. These participants provided feedback throughout questionnaires, including the System Usability Scale, Working Alliance Inventory and other crafted questions that aimed to evaluate feasibility and acceptability, as well as capture their perceptions and suggested improvements. The iTakeCharge study steps for system design, protocol intervention, feedback collection, system modification, as well as the discussion of the human-computer interaction approach to deliver self-management intervention for stroke recovery are presented in this thesis.

description: The properties of non-product states, both (anti)symmetrized and entangled, have been extensively studied in the literature. In this paper, by extending previous partial results, we introduce a general framework to describe atomic absorption and emission in these states. Our approach shows the existence of some fundamental differences between entanglement and (anti)symmetrization and between absorption and emission. For instance, modifications of the emission properties with respect to that of uncorrelated systems occur for any (anti)symmetrized state but only for some very specific entangled states.

description: Conventional dual-frequency fringe projection algorithm often suffers from phase unwrapping failure when the frequency ratio between the high frequency and the low one is too large. Zhang et.al. proposed an enhanced two-frequency phase-shifting method to use geometric constraints of digital fringe projection(DFP) to reduce the noise impact due to the large frequency ratio. However, this method needs to calibrate the DFP system and calculate the minimum phase map at the nearest position from the camera perspective, these procedures are are relatively complex and more time-cosuming. In this paper, we proposed an improved method, which eliminates the system calibration and determination in Zhang's method,meanwhile does not need to use the low frequency fringe pattern. In the proposed method,we only need a set of high frequency fringe patterns to measure the object after the high frequency is directly estimated by the experiment. Thus the proposed method can simplify the procedure and improve the speed. Finally, the experimental evaluation is conducted to prove the validity of the proposed method.The results demonstrate that the proposed method can overcome the main disadvantages encountered by Zhang's method.

description: Blue metal-poor stars (BMPs) are main sequence stars that appear bluer and more luminous than normal turnoff stars. They were originally singled out by using B-V and U-B colour cuts. Early studies found that a larger fraction of field BMP stars were binaries compared to normal halo stars. Thus, BMP stars are ideal field blue straggler candidates for investigating internal stellar evolution processes and binary interaction. In particular, the presence or depletion in lithium in their spectra is a powerful indicator as to their origin. They are either old, halo blue stragglers experiencing internal mixing processes or mass transfer (Li-depletion), or intermediate-age, single stars of possibly extragalactic origin (2.2dex halo plateau Li). However, we note that internal mixing processes can lead to an increased level of Li. Hence, this study combines photometry and spectroscopy to unveil the origin of various BMP stars. We first show how to separate binaries from young blue stars using photometry, metallicity, and lithium. Using a sample of 80 BMP stars (T>6300K), we find that 97% of the BMP binaries have V-Ks_0 < 1.08$\pm0.03$, while BMP stars that are not binaries lie above this cut in 2/3 of the cases. This cut can help classify stars which lack radial velocities from follow-up observations. We trace the origin of two BMP stars from the photometric sample by conducting a full chemical analysis using new high-resolution and high SN spectra. Based on their radial velocities, Li, alpha, and s- and r-process abundances we show that BPS CS22874-042 is a single star (A(Li)$=2.38\pm0.10$dex) while with A(Li)$=2.23\pm0.07$dex CD-48 2445 is a binary, contrary to earlier findings. Our analysis emphasises that field blue stragglers can be segregated from single metal-poor stars, using V-Ks colours with a fraction of single stars polluting the binary sample, but not vice versa.(Abridged)

description: SCIAMACHY (Scanning Imaging Absorption Spectrometer for Atmospheric Chartography) on-board the ESA Envisat satellite platform provided daily solar spectra in the wavelength region from 0.24 μm to 2.4 μm. The instrument was operating for nearly a decade from August 2002 to April 2012. This document reports on the validation of the SCIAMACHY solar spectral irradiances (SSI) in its data version 8. Like other UV satellite sounders, the SCIAMACHY spectrometer suffers from optical degradation due to polymerisation of optical surfaces from the harsh UV radiation in space (e.g. Bramstedt et al., 2009; DeLand et al., 2012; Krijger et al., 2014). In data version 8 of SCIAMACHY a physical model of the scanner unit was implemented to provide a degradation correction (Bramstedt et al., 2009; Krijger et al., 2014). Comparisons with several other established solar reference spectra show agreement to within 4 % in most parts of the visible and near infrared from 350 to 1400 nm.

description: We report on the discovery of a hydrogen-deficient compact binary (CXOGBS J175107.6-294037) belonging to the AM CVn class in the Galactic Bulge Survey. Deep archival X-ray observations constrain the X-ray positional uncertainty of the source to 0.57 arcsec, and allow us to uniquely identify the optical and UV counterpart. Optical spectroscopic observations reveal the presence of broad, shallow He i absorption lines while no sign of hydrogen is present, consistent with a high state system. We present the optical lightcurve from Optical Gravitational Lensing Experiment monitoring, spanning 15 years. It shows no evidence for outbursts; variability is present at the 0.2 mag level on timescales ranging from hours to weeks. A modulation on a timescale of years is also observed. A Lomb-Scargle analysis of the optical lightcurves shows two significant periodicities at 22.90 and 23.22 min. Although the physical interpretation is uncertain, such timescales are in line with expectations for the orbital and superhump periods. We estimate the distance to the source to be between 0.5 - 1.1 kpc. Spectroscopic follow-up observations are required to establish the orbital period, and to determine whether this source can serve as a verification binary for the eLISA gravitational wave mission.

Ranks of the Rational Points of Abelian Varieties over Ramified Fields, and Iwasawa Theory for Primes with Non-Ordinary Reduction

description: Let $A$ be an abelian variety defined over a number field $F$. Suppose its dual abelian variety $A'$ has good non-ordinary reduction at the primes above $p$. Let $F_{\infty}/F$ be a $\mathbb Z_p$-extension, and for simplicity, assume that there is only one prime $\mathfrak p$ of $F_{\infty}$ above $p$, and $F_{\infty, \mathfrak p}/\mathbb Q_p$ is totally ramified and abelian. (For example, we can take $F=\mathbb Q(ζ_{p^N})$ for some $N$, and $F_{\infty}=\mathbb Q(ζ_{p^{\infty}})$.) As Perrin-Riou did, we use Fontaine's theory of group schemes to construct series of points over each $F_{n, \mathfrak p}$ which satisfy norm relations associated to the Dieudonne module of $A'$ (in the case of elliptic curves, simply the Euler factor at $\mathfrak p$), and use these points to construct characteristic power series $\bf L_α \in \mathbb Q_p[[X]]$ analogous to Mazur's characteristic polynomials in the case of good ordinary reduction. By studying $\bf L_α$, we obtain a weak bound for $\text{rank} E(F_n)$. In the second part, we establish a more robust Iwasawa Theory for elliptic curves, and find a better bound for their ranks under the following conditions: Take an elliptic curve $E$ over a number field $F$. The conditions for $F$ and $F_{\infty}$ are the same as above. Also as above, we assume $E$ has supersingular reduction at $\mathfrak p$. We discover that we can construct series of local points which satisfy finer norm relations under some conditions related to the logarithm of $E/F_{\mathfrak p}$. Then, we apply Sprung's and Perrin-Riou's insights to construct \textit{integral} characteristic polynomials $\bf L_{alg}^{\sharp}$ and $\bf L_{alg}^{\flat}$. One of the consequences of this construction is that if $\bf L_{alg}^{\sharp}$ and $\bf L_{alg}^{\flat}$ are not divisible by a certain power of $p$, then $E(F_{\infty})$ has a finite rank modulo torsions.

description: We report on six new Chandra observations of the Geminga pulsar wind nebula (PWN). The PWN consists of three distinct elongated structures - two $\approx 0.2 d_{250}$ pc long lateral tails and a segmented axial tail of $\approx 0.05 d_{250}$ pc length, where $d_{250}=d/(250 {\rm pc})$. The photon indices of the power law spectra of the lateral tails, $Γ\approx 1$, are significantly harder than those of the pulsar ($Γ\approx 1.5$) and the axial tail ($Γ\approx 1.6$). There is no significant diffuse X-ray emission between the lateral tails -- the ratio of the X-ray surface brightness between the south tail and this sky area is at least 12. The lateral tails apparently connect directly to the pulsar and show indication of moving footpoints. The axial tail comprises time-variable emission blobs. However, there is no evidence for constant or decelerated outward motion of these blobs. Different physical models are consistent with the observed morphology and spectra of the Geminga PWN. In one scenario, the lateral tails could represent an azimuthally asymmetric shell whose hard emission is caused by the Fermi acceleration mechanism of colliding winds. In another scenario, the lateral tails could be luminous, bent polar outflows, while the blobs in the axial tail could represent a crushed torus. In a resemblance to planetary magnetotails, the blobs of the axial tail might also represent short-lived plasmoids which are formed by magnetic field reconnection in the relativistic plasma of the pulsar wind tail.

Je mehr, desto weniger? Das Verhältnis von Wachstumskritik und alternativen Wirtschaftskonzepten des Postwachstums zum kapitalistischen System
Creators: name: Wilmsen, Felix
Publisher: name: Universität Bremen
Year: 2015
Subjects: subject: Postwachstum
subject: Wachstumskritik
subject: 330

description: Seit der Jahrtausendwende nimmt eine Bewegung Fahrt auf, die Ungerechtigkeiten und globale ökologische Problemlagen als direkte und indirekte Folgen einer kompromisslosen Wachstumsorientierung deutet. Mit den Debatten um Konvivialismus und neue Ansätze solidarischer Ökonomie mehren sich zugleich die Versuche, Formen des guten Zusammenlebens jenseits der Zwänge des Wachstumsparadigmas zu suchen und eine Ära des „Postwachstums“ einzuläuten. Felix Wilmsen untersucht in seiner Studie zentrale Diskursstränge der Wachstumskritik und ihr Verhältnis zur kapitalistischen Wirtschaftsordnung. In einer anspruchsvollen theoretischen Analyse identifiziert er Konfliktlinien und Spannungspunkte zwischen der kapitalistischen Gegenwart und den Zukunftsentwürfen des Postwachstumsdiskurses. Sein theoretischer Zugriff ist dabei bewusst kritisch und folgt einem neomarxistischen Ansatz.

Non-homogeneous square functions on general sets: suppression and big pieces methods

description: We aim to showcase the wide applicability and power of the big pieces and suppression methods in the theory of local $Tb$ theorems. The setting is new: we consider conical square functions with cones $\{x \in \mathbb{R}^n \setminus E: |x-y| < 2 \operatorname{dist}(x,E)\}$, $y \in E$, defined on general closed subsets $E \subset \mathbb{R}^n$ supporting a non-homogeneous measure $μ$. We obtain boundedness criteria in this generality in terms of weak type testing of measures on regular balls $B \subset E$, which are doubling and of small boundary. Due to the general set $E$ we use metric space methods. Therefore, we also demonstrate the recent techniques from the metric space point of view, and show that they yield the most general known local $Tb$ theorems even with assumptions formulated using balls rather than the abstract dyadic metric cubes.

title: Human sustainability, relational coordination and worker outcomes
Creators: name: Meleti, Elli
Publisher: name: University of Glasgow
Year: 2020
Subjects: subject: Human sustainability, relational coordination, stakeholder management, work engagement, proactive work behaviour, job satisfaction.

description: This study focuses on human sustainability in the university context and argues that human sustainability in this context and elsewhere needs to take a more central position in research, education, business and public policy. Its contribution to knowledge is twofold: First, this thesis aims to make a contribution to the theory of relational coordination, which argues that the personal transformation of people in organisations is fundamental for organisational and social transformation, by explaining how the personal transformation of people takes place in the university context and how the University can help its employees to positively transform themselves. Second, this thesis aims to legitimise the concept of human sustainability by theorising and defining it, given that theory and research on this topic remain limited.
Indirect Regulation: A Remedy to Cure the Defects of European Environmental Policy? – The EMAS-Regulation
Creators: name: Becke, Guido
Publisher: name: Universität Bremen
Year: 2004
Subjects: subject: Eco-Management and Audit Scheme (EMAS)
subject: Umweltpolitik
subject: 320

description: The Eco-Management and Audit Scheme (EMAS) belongs to new forms of reflexive or indirect regulation in European environmental policy. The development of European environmental policy is outlined in respect to indirect regulation. By the example of EMAS the paper analyses the impacts of indirect regulation. At the first level the analysis focuses on the EMAS-participation within the European Union emphasising that EMAS turns out to be more a German rather than a European project. At the second level the analysis concentrates on the effects of EMAS-participation in respect to in-company processes of ecological modernisation as well as to external, mainly market-based impacts. The results are ambivalent: Positive effects are an improved level of in-company environmental protection and enhanced legal compliance. However, innovative potentials to organisational environmental learning are only partly exhausted. Market effects and improved relationships to external stakeholders seldom occur. To attribute these outcomes to specific instruments of environmental regulation would negate the multi-level and multi-centred institutional setting of European environmental policy. Therefore, starting points for a more effective European environmental policy are discussed, which combine aspects and instruments of direct and indirect regulation. Moreover, options to increase the participation of firms in EMAS are outlined.

description: Mail order companies like Zalando or Amazon reported a significant increase regarding the number of incoming customer orders in recent years. Customers are served from a central distribution center (warehouse) where requested items of the orders have to be retrieved (picked) from their storage locations. The picking process is performed by human operators (order pickers) who are employed on a large scale in order to enable a fast processing of the orders. However, due to limited space, aisles are often very narrow in warehouses, and order pickers cannot pass or overtake each other. Thus, an order picker may have to wait until another picker has performed his/her operations. The arising waiting times may significantly increase the processing times of the orders, implying that a large number of pickers does not guarantee for small processing times. Therefore, in this paper, the impact of several problem parameters on the amount of waiting time is investigated first and situations are identified where the consideration of waiting times is inevitable for an efficient organization of the picking process. In the second part of the paper, a solution approach, namely a truncated branch-and-bound algorithm, is proposed which aims for the minimization of the waiting times. By means of extensive numerical experiments, it is demonstrated that this approach provides high-quality solutions within a very small amount of computing time.

description: Der Aufsatz unterstreicht – schwerpunktmäßig aus einer (religions)didaktischen Perspektive – die Relevanz der Beziehungsdimension für das Gelingen von Lehr- und Lernprozessen.  Vier Mosaiksteine beleuchten verschiedene Facetten des Themas. Mit der anschließenden kurzen Reflexion des „Lernens am Modell“, eines systemisch-konstruktivistischen Ansatzes in der Didaktik sowie der Bedeutung des Feedback-Gebens werden einige Aspekte einer professionellen Beziehungskompetenz aufgegriffen, die für die LehrerInnenbildung besonders bedeutsam erscheinen.
description: This paper stresses the importance of relationship for functioning teaching and learning processes. It does so from a mainly didactic perspective. Four aspects of the topic are highlighted, and then a short reflection on the “learning on a model” approach is given. Based on this systemic-constructivist approach in didactics and by stressing the importance of giving feed-back, some aspects of acquiring professional competence in building relationships, that are especially important for teacher education, are being highlighted.

Der Kampf des Gehirns gegen eindringende Krebszellen

description: Auch heute noch versterben viele Menschen an den Folgen der Metastasierung durch solide Tumore (Lungenkrebs, Dickdarmkrebs, Brustkrebs etc.). Dennoch sind der genaue zeitliche Ablauf und die molekularen Mechanismen nur partiell verstanden. Vereinfacht kann dieser komplexe Prozess nach dem Aufenthaltsort der Krebszellen in drei Blöcke eingeteilt werden: i) die Phasen am Entstehungsorgan; ii) die Phasen im Blut- oder Lymphsystem; iii) und die Phasen im fremden Organ. In den letzten Jahren hat man durch genetische Untersuchungen festgestellt, dass sich erfolgreich metastasierte Krebszellen früher als erwartet vom Entstehungsort lösen und sich andernorts sogar weiter entwickeln (parallele Evolution). Zudem ist bekannt geworden, dass sich bei vielen Patienten Krebszellen im Blut oder Knochenmark nachweisen lassen, die aber erstaunlicherweise später keine Metastasen entwickeln. Somit müssen viele Krebszellen noch im Blut oder im fremden Organ erfolgreich aufgehalten werden. Aber gerade die letzten Phasen der Metastasierung im fremden Organ sind nur rudimentär erforscht. Interessanterweise ergaben einige Arbeiten, das beinahe alle Krebszellen kurz nach dem Austritt aus dem Blutgefäß in dem fremden Organ sehr schnell absterben. Somit scheint das Überleben in einer unbekannten Umgebung für die Krebszellen nicht nur das größte Hindernis, sondern auch der entscheidende Faktor über Leben und Tod zu sein. Aus diesen Gründen widmet sich unsere Arbeitsgruppe intensiv dieser letzten Phase der Metastasierung und der Frage, wie sich das fremde Organ gegen eindringende Krebszellen wehrt.
