description: Urban and peri-urban natural areas can serve as critical refugia for biodiversity and provide key ecosystem services, despite pressures from habitat fragmentation, invasive species, and climate change. Understanding which species inhabit these spaces over time is crucial, as this information both inspires conservation efforts and informs effective management strategies. However, collecting the necessary data to guide conservation efforts requires robust, ongoing monitoring. Community science, in which volunteers participate in data collection, addresses this need by enabling widespread, cost-effective data collection across large temporal and spatial scales. Beyond the value of the data itself, community science fosters ecological stewardship by connecting local communities with their natural areas, which increases participation in management activities and improves habitat quality. In southeastern Michigan, the City of Ann Arbor Parks & Recreation Department's Natural Area Preservation (NAP) division has collected nearly 30 years worth of ecological data in city parks and natural areas through community science wildlife surveys. These programs target three taxa—birds, butterflies, and herpetofauna (herps; referring to amphibians and reptiles)—and have amassed thousands of observations. Having data over so many years and across many different parks provides a rare opportunity to get a picture of which species are supported over time and how that has changed, and how that relates to site features and management efforts. However, in-depth analysis of large and complex datasets requires time and effort. Recognizing both the value of their datasets and the need for a more comprehensive analysis of outcomes to date, the City initiated a collaboration with our team of master’s students from the University of Michigan School for Environment and Sustainability in January 2024. 2 Our collaboration produced a suite of deliverables tailored to three key audiences: the City of Ann Arbor, local community volunteers, and urban ecology researchers. These include an internal report and data repository with R code to support NAP’s adaptive management and future analyses, an ArcGIS StoryMap for public engagement, a peer-reviewed paper to inform standardization methods for community science data use, and two professional conference presentations, the Natural Areas Association Conference 2024 and The Stewardship Network Conference 2025.
A theory of multinational banking

description: The paper represents a first attempt to develop a general theory of multinational banking capable of explaining the phenomenon with the help of a few price-theoretic principles. Such theorising is useful in the discussion of policy issues raised by the recent rapid growth of multinational banking and by proposed US legislation designed to curb it. The basic analytical question regards the source of comparative advantage. Specifically, the author looks at how a bank abroad can profitably offer lower lending and higher borrowing rates than its domestic competitors and thus attract customers away from them.

Partition functions of the tensionless string

description: We consider string theory on $\text{AdS}_3 \times \text{S}^3 \times \mathbb{T}^4$ in the tensionless limit, with one unit of NS-NS flux. This theory is conjectured to describe the symmetric product orbifold CFT. We consider the string on different Euclidean backgrounds such as thermal $\text{AdS}_3$, the BTZ black hole, conical defects and wormhole geometries. In simple examples we compute the full string partition function. We find it to be independent of the precise bulk geometry, but only dependent on the geometry of the conformal boundary. For example, the string partition function on thermal $\text{AdS}_3$ and the conical defect with a torus boundary is shown to agree, thus giving evidence for the equivalence of the tensionless string on these different background geometries. We also find that thermal $\text{AdS}_3$ and the BTZ black hole are dual descriptions and the vacuum of the BTZ black hole is mapped to a single long string winding many times asymptotically around thermal $\text{AdS}_3$. Thus the system yields a concrete example of the string-black hole transition. Consequently, reproducing the boundary partition function does not require a sum over bulk geometries, but rather agrees with the string partition function on any bulk geometry with the appropriate boundary. We argue that the same mechanism can lead to a resolution of the factorization problem when geometries with disconnected boundaries are considered, since the connected and disconnected geometries give the same contribution and we do not have to include them separately.

description: Australia is the world's front runner in farmer-driven R&D system reforms. Collective funding bodies operate on the farmers' levy, and they budget public R&D projects satisfying farmers' needs. This paper applies an innovation system perspective to explain how those funding bodies steer R&D at the following stages: project setup, project management, and farmer adoption. The behaviors of actors in the system, such as managers of the funding body (Meat&Livestock Australia Ltd., MLA), researchers, and extension officers are examined. The findings are as follows: (i) Effective interactions among actors are observed in the northern beef sector. (ii) MLA promoted and controlled the interaction by flexibly designing who and how to interact at each stage. (iii) From the interaction, MLA obtained local specific information, such as farmers' technical problems, researchers' abilities, and research progress, which served as a basis for steering R&D rightly.
title: Sea ice thickness and iceberg distribution in the Southern Ocean
Creators: name: Banks, Christopher J.
Publisher: name: The Open University
Year: 2007

description: The sea ice thickness distribution, represented by the probability density function (PDF), is critical to Earth's climate system and knowledge of the distribution in the Antarctic is limited. A novel methodology, using an acoustic Doppler current profiler, was developed to measure sea ice draft based on measurements taken from Autosub (an autonomous underwater vehicle). The PDF has been derived for three missions undertaken in the eastern Amundsen Sea during March 2003. The PDFs for all missions were found to have a single mode although there is evidence for variability in mean thickness along the ice front, as the most western mission has a lower mean draft. Geostatistical analyses of the data have allowed the derivation of PDFs to account for the spatial sampling.

 A factor on the thickness of ice measured is the presence of icebergs within a study region. This thesis reports on work carried out to investigate whether a correction to the sea ice thickness PDF can be made to account for icebergs and over what scale(s) this correction is valid. To answer this question data from Autosub and satellite images were used to investigate whether icebergs were randomly distributed both in open ocean and within sea ice. In conclusion, it was found that icebergs do cluster on the scale of typical Autosub missions (~few km). However, there are differences between icebergs in sea ice compared with open water. Therefore, icebergs should be accounted for in the sea ice thickness PDF.

description: This paper aims to investigate the effects of the mass food poisoning caused by processed milk and the intentional mislabeling of beef on the market risk of the excess stock returns of three companies in the Japanese milk industry by using the event-study methodology, a branch of financial econometrics. The dynamic conditional correlation GARCH model is fit to the excess return data to estimate the volatilities and dynamic conditional correlations of the corporations concerned. The results show that both events rapidly change the volatilities of the mentioned company and that these events influence the volatilities of one of the remaining two companies. Moreover, we find that the dynamic conditional correlations between this firm and the other firms changed rapidly when the beef mislabeling scandal was exposed but changed gradually when the mass food poisoning occurred. Therefore, one can conclude that the stock market can react immediately to unethical behavior of food-related firms.
Inverse Cosmography: testing the effectiveness of cosmographic polynomials using machine learning

description: Cosmography has been referred to as a solution to the inverse scattering problem, which is reasonable since it allows us to calculate cosmological bounds from data samplers by performing an expansion of the cosmological observables around present time. Nevertheless, this approach is not properly an inverse scattering solution since the method only circumvents the problem to fit the equation of state (EoS) parameters (model-dependent) by replacing it with their fit of its cosmographic parameters (with a polynomial series-dependence). Therefore, can we construct a new cosmography approach where the cosmodynamical parameters can be fitted and then employ them to analyse the kinematics via its generic cosmographic parameters? By all means, without experimenting the problem of truncation of the series that all cosmography proposals in the literature argue. In this work we present a generic EoS depending solely on the form of $f_i(z)$ and its derivative is found, where this function can be any polynomial (mimicking a dark energy-like term) that allow the dynamics of a specific cosmological density. We test our generic EoS with standard cosmological models and with polynomials proposals as Padé and Chebyshev approximants. Interesting enough, a Padé (2,2) approximant has been considered inside a $f(z)$CDM-like model showing a transition in $z=1$. Also, we found that this is not assured since models with these characteristics have degeneracy and truncation problems that experiment a divergence at this redshift limit. To explore our results, also we present a new supernovae sample trained via a deep learning tool called Recurrent-Bayesian (RNN+BNN) network that can solve problems as overfitting at lower redshifts and increase the density of data points in this region, which can help to discern between cosmographies at 2-$σ$ of precision.

description: We tested the hypothesis that decrements in arterial oxyhaemoglobin saturation could be related to elevations in circulating endothelin-1 following 30 minutes of exercise at ventilatory threshold. Eight aerobically trained males (mean ± SEM: age 26.14 ± 1.77 years, height 182.36 ± 1 . 5 1 cm, mass 72.89 ± 2.62 kg) completed 2 maximal exercise tests (mean ± SEM: normoxia (n) 68.56 ± 2.06 mL.kg-¹min-¹; hypoxia (Fi02 0.14)(h) 53.88 ± 1.35 mL.kg-¹.min-¹), and two 30-minute steady state exercise protocols at the power achieved at threshold during maximal exercise tests (mean ± SEM: power (Watts) 257.14 ± 21.57 (n) 191.25 ± 10.79 (Fi02 0.14)(h); HR (bpm) 161.7 ± 5.34 (n) 156.6 ± 3.45 (h)). When participants exercised for 30 minutes at ventilatory threshold inspiring 14%02, a significant decrease in oxygen saturation (as measured by pulse oximetry) was observed, when compared to values in normoxia (80.2 ± 1.17 % (h) vs 94.12 ± 0.24 % (n); p<0.001). This desaturation was not accompanied by significant changes in plasma endothelin-1 (ET-1), big endothelin-1 (BigET-1) or nitric oxide (NO). Both pulmonary artery pressure (PAP) and oscillatory compliance (OC) were significantly greater following exercise (F[superscript omitted] = 4.74 p< 0.05), compared to pre-exercise values. These outcome variables were not different between normoxia and hypoxia. Plasma ET-1 or BigET-1 levels did not differ significantly over time or across conditions F[superscript omitted] = 4.74 p> 0.05). In conclusion, plasma ET-1 levels following 30-minutes of steady state exercise at ventilatory threshold are unrelated to decrements in oxyhaemoglobin saturation.

description: Once, OGURA Takekazu, who is one of the key persons behind the Agricultural Basic Law, made the following reflection. "I was caught by the theory of Western Europe and couldn't think over the reality of Japanese agriculture profoundly. It was necessary to conduct a study on the character of Japanese agriculture and the rural community, and to plan the structural reform based on it." The theme of this paper is to consider the type of structural reform based on the reflection of OGURA. The main reason why the agricultural structural reform hasn't proceeded well in Japan is that agricultural administration disregarded the power of rural society. In a traditional Japanese rural community, i. e., each plot of arable land was a separate territory, and its property rights belonged to the family of each peasant. In such a rural community with this tradition, it is necessary for agricultural administration to declare it would insure that farmers could defend their farmland property rights in the first place, and after that, to devise a way to to separate use right from the ownership of the arable land to execute the structural reform. After the mutual agreement of the landowners' group in the rural community is completed, it is necessary to entrust the farm management to a reliable person or group who has managerial skills. However, there is a great deal of room for the invention of these methods in each region. Therefore, the types might be diversified and a long term is also required. In the above-mentioned points, Japanese type agricultural structural reform will be greatly different from the image that WTO holds. It is necessary for agricultural administration to declare these clearly inside and outside Japan.

description: The combination of optical and mid-infrared (MIR) photometry has been extensively used to select red active galactic nuclei (AGNs). Our aim is to explore the obscuration properties of these red AGNs with both X-ray spectroscopy and spectral energy distributions (SEDs). In this study, we re-visit the relation between optical/MIR extinction and X-ray absorption. We use IR selection criteria, specifically the $W1$ and $W2$ WISE bands, to identify 4798 AGNs in the $\it{XMM-XXL}$ area ($\sim 25$deg$^2$). Application of optical/MIR colours ($r- W2 > 6$) reveals 561 red AGNs (14$\%$). Of these, 47 have available X-ray spectra with at least 50 net (background-subtracted) counts per detector. For these sources, we construct SEDs from the optical to the MIR using the CIGALE code. The SED fitting shows that 44 of these latter 47 sources present clear signs of obscuration based on the AGN emission and the estimated inclination angle. Fitting the SED also reveals ten systems ($\sim20\%$) which are dominated by the galaxy. In these cases, the red colours are attributed to the host galaxy rather than AGN absorption. Excluding these ten systems from our sample and applying X-ray spectral fitting analysis shows that up to $76\%$ (28/37) of the IR red AGNs present signs of X-ray absorption. Thus, there are nine sources ($\sim20\%$ of the sample) that although optically red, are not substantially X-ray absorbed. Approximately $50\%$ of these sources present broad emission lines in their optical spectra. We suggest that the reason for this apparent discrepancy is that the r-W2 criterion is sensitive to smaller amounts of obscuration relative to the X-ray spectroscopy. In conclusion, it appears that the majority of red AGNs present considerable obscuration levels as shown by their SEDs. Their X-ray absorption is moderate with a mean of $\rm N_H \sim 10^{22}\, \rm{cm^{-2}}$.

description: In Japan, the continuous reduction in family size during the post-war period has caused a decline in the efficiency of domestic production in households. The proportion of expenditure on foodstuffs for homemade meals in total food expenses has decreased; on the other hand, the proportion of expenditure on convenience foods (cooked food, fast food, etc.) and eating-out has increased. The changes in the diet of Japanese people prevent the household consumption of domestic agricultural products. The objective of this study is to provide a baseline about food consumption from the viewpoint of the household demand-side and to find a measure, which acts as a brake on the decrease in the household consumption of domestic agricultural products. The main outcomes of this study are as follows. First, the changes in the dietary habits of Japanese households during the post-war period depend on the economic factors associated with Japanese economy at that time in spite of dietetic issues. Second, the household consumption of domestic agricultural products is going to decline if we maintain the same conditions. Third, an improvement in the efficiency of domestic agricultural production is essential for keeping the volume of household demand for domestic products since progress in the efficiency of homemade meals is difficult for today's households. This is the measure of cooperation between households and domestic agriculture the study suggests.

description: This article analyzes the agricultural structure among rice sector, livestock sector, and vegetable sector in Japan, adopting the viewpoint of the movement of main production areas. This article also considers the influences of international market access, production adjustment, cultivated land lease market, land improvement and the logic of the farm household. The livestock and the vegetable sector experienced a structural change including the moves of the main production to areas such as Hokkaido and Kyushu, which had an economic rationality from the geographical point of view. Behind this change, there was stiff market competition from abroad as well as domestic products and improvement of infrastructure in production areas. In contrast, the rice sector maintains production areas widely all over Japan, and there are many small-scale rice farmers that don't aim at profit, while large-scale rice farm managements occupy a constant share of the rice sector of Japan. The issue of the structure of Japanese agriculture depends how the rice sector changes.

Abstract

Future climate and sea level projections depend sensitively on Antarctic Ice Sheet response to ocean-driven melting and the resulting freshwater fluxes into the Southern Ocean. Circumpolar Deep Water (CDW) in the Southern Ocean is increasingly recognised as a crucial heat source for ice shelf melt. Quantifying past changes in the temperature of CDW is therefore of great benefit for modelling ice sheet response to past warm climates, and for putting recent and projected CDW temperature changes into context. Here we use marine sedimentary evidence to estimate CDW temperature changes over the last eight glacial-interglacial cycles (800,000 years). Estimated interglacial warming reached 0.6 ± 0.4 °C relative to present, while glacial cooling was typically −1.5 to −2 °C. The peak warmth occurred in the last interglacial, when sea-levels were a few metres higher than present. For comparison, observations indicate CDW warming of around 0.1 °C/decade since the 1990s, while climate projections (CMIP6 SP585) suggest 0.6 °C warming could already be reached by 2100.

description: Magnetic chemically peculiar (mCP) stars are important to astrophysics because their complex atmospheres lend themselves perfectly to the investigation of the interplay between such diverse phenomena as atomic diffusion, magnetic fields, and stellar rotation. The present work is aimed at identifying new mCP stars using spectra collected by the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST). Suitable candidates were selected by searching LAMOST DR4 spectra for the presence of the characteristic 5200A flux depression. Spectral classification was carried out with a modified version of the MKCLASS code and the accuracy of the classifications was estimated by comparison with results from manual classification and the literature. Using parallax data and photometry from Gaia DR2, we investigated the space distribution of our sample stars and their properties in the colour-magnitude diagram. Our final sample consists of 1002 mCP stars, most of which are new discoveries (only 59 previously known). Traditional mCP star peculiarities have been identified in all but 36 stars, highlighting the efficiency of the code's peculiarity identification capabilities. The derived temperature and peculiarity types are in agreement with manually derived classifications and the literature. Our sample stars are between 100 Myr and 1 Gyr old, with the majority having masses between 2M(Sun) and 3M(Sun). Our results could be considered as strong evidence for an inhomogeneous age distribution among low-mass (M < 3M(Sun)) mCP stars. We identified several astrophysically interesting objects: two mCP stars have distances and kinematical properties in agreement with halo stars; an eclipsing binary system hosting an mCP star component; and an SB2 system likely comprising of an mCP star and a supergiant component.

title: Molecular phylogeny, phylogeography and population genetics of the red seaweed genus Asparagopsis
Creators: name: Andreakis, Nikolaos
Publisher: name: The Open University
Year: 2006

description: The red seaweed genus Asparagopsis Montagne (Bonnemaisoniales) was studied with respect to its taxonomy, phylogeny, phylogeography and population genetics. The representatives of this genus, A. armata Harvey and A. taxiformis (Delile) Trevisan, are notorious invaders. Both species occur worldwide and show disjunct distribution patterns. Such patterns may result from recent jump-dispersal or from fragmentation of once panglobally distributed species. First, a phylogeographic approach was deployed in order to delineate the taxonomic units in local scale and to assess if European populations of each of the species originated from a single introduction or multiple cryptic ones. Results showed that the two species recognized A. armata and A. taxiformis are also genetically distinct. Asparagopsis armata was found to consist of a single species worldwide, whereas A. taxiformis constituted three and probably four morphologically cryptic but genetically distinct lineages. At times, lineages were encountered in sympatry and two of them were detected in the Mediterranean Sea.

In order to confirm distinction between lineages and to assess invasive potential and colonization mechanisms of the species along the western Italian coast, eight nuclear micro satellite markers were identified against the invasive lineage 2 of A. taxiformis. The markers cross-hybridised only with lineages I and 2. Moreover, it was demonstrated that carpogonia present on many female thalli can affect microsatellite reading patterns because of external (male) allelic contribution. Even after removal of the carpogonia, gametophyte thalli exhibited multiple allelic patterns, which is indicative for polyploidy. The markers were then used to assess genetic structure and diversity within and among Mediterranean populations of A. taxiformis lineages 1 and 2. Analyses based on statistics developed for polyploid species showed that the lineage l-population (HAW) was distinct from Mediterranean lineage 2 populations. A geographically distant Californian lineage 2· population was genetically distinct from the Mediterranean ones as well. The Mediterranean lineage 2-samples showed panmixia. High genotypic diversity, high gene flow, and low differentiation encountered amongst these populations probably are due to a recent invasion of this lineage into the basin.

Publisher: name: PSL Quarterly Review
Year: 2014
Subjects: subject: IMF, special drawing right, SDR, international monetary system
subject: F33, E42

description: The amended articles of the IMF stipulate that member countries must cooperate with the IMF and among themselves to make the special drawing right (SDR) the principle reserve instrument of the international monetary system. The present paper discusses some of the issues which will have to be analysed in this framework. It deals first with the role of the SDR after the important changes which have taken place in the international monetary system. It then stresses the present weaknesses of the SDR and goes on to make suggestions as to how they could be dealt with. JEL: F33, E42

description: Advanced AO systems will likely utilise Pyramid wave-front sensors (PWFS) over the traditional Shack-Hartmann sensor in the quest for increased sensitivity, peak performance and ultimate contrast. Here, we wish to bring knowledge and quantify the PWFS theoretical limits as a means to highlight its properties and use cases. We explore forward models for the PWFS in the spatial-frequency domain for they prove quite useful since a) they emanate directly from physical-optics (Fourier) diffraction theory; b) provide a straightforward path to meaningful error breakdowns, c) allow for reconstruction algorithms with $O (n\,log(n))$ complexity for large-scale systems and d) tie in seamlessly with decoupled (distributed) optimal predictive dynamic control for performance and contrast optimisation. All these aspects are dealt with here. We focus on recent analytical PWFS developments and demonstrate the performance using both analytic and end-to-end simulations. We anchor our estimates with observed on-sky contrast on existing systems and then show very good agreement between analytical and Monte-Carlo estimates for the PWFS. For a potential upgrade of existing high-contrast imagers on 10\,m-class telescopes with visible or near-infrared PWFS, we show under median conditions at Paranal a contrast improvement (limited by chromatic and scintillation effects) of 2x-5x by replacing the wave-front sensor alone at large separations close to the AO control radius where aliasing dominates, and factors in excess of 10x by coupling distributed control with the PWFS over most of the AO control region, from small separations starting with the Inner Working Angle of typically 1-2 $λ/D$ to the AO correction edge (here 20 $λ/D$).

Targets and techniques of monetary policy in Western Europe
Creators: name: MCCLAM, W.D.
Publisher: name: PSL Quarterly Review
Year: 2014
Subjects: subject: Growth targets, monetary policy, interest rate, monetary aggregates
subject: E52, E43

description: In recent years a growing number of western European countries have adopted the practice of setting growth targets for money supply and/or other monetary aggregates. For these countries, of course, the new approach has implied a shift away from reliance upon interest rate objectives as an intermediate target of policy. This article looks at the story lying behind the spreading use of this technique. In particular, the author examines whether central banks have suddenly become converted to the precepts of “monetarism”, or rather whether this shift is simply a pragmatic response to changing economic environment. The reasons for the adoption of published monetary targets is first analysed. Then, international comparisons of target fixing and their results are made and the problems of targeting are considered.

Fiscal versus monetary rules
Creators: name: VACIAGO, G.
Publisher: name: PSL Quarterly Review
Year: 2014
Subjects: subject: Inflation, monetary targets, England, deficit, money supply, credit, policy
subject: E63, E44, E52

description: In recent years policy-makers have been confronted with the twin tasks of reducing the pace of inflation and attempting to stabilise the economy, while these very problems make the outcome of their policies less certain. An attempt to break this vicious circle has been the adoption, in several countries, of publicly announced monetary targets. In 1976 the British Government provided publicly quantified targets for not one but three different variables: the public sector deficit, money supply, and domestic credit. Not surprisingly, this strategy based on multiple targets raises a host of questions. The present article tackles some of these questions by examining, first, the assumptions that lead to a rule for each of the three variables. Then the author quantifies their differences with a simulation experiment, using a simplified macroeconomic model capable of reproducing the main features of those opposite approaches.

description: Die vorliegende Literaturarbeit untersucht den aktuellen Forschungsstand zum integrativen Sport-unterricht mit Kindern mit externalisierendem Verhalten. Externalisierendes Verhalten ist eine Ver-haltensstörung die sich insbesondere durch aggressives, impulsives, überaktives und mitunter regel-verletzendes Verhalten beschreiben lässt. Die Facetten der Thematik werden im ersten Teil der Ar-beit anhand des Wissensstands der Fachliteratur aufgezeigt. Der zweite Teil beinhaltet ein Literaturreview. Bei der systematischen Literaturrecherche in deutsch- und englischsprachigen Fachdatenbanken wurden 569 Treffer (mit Doppelnennungen) erzielt, wobei 52 Artikel als relevant bezeichnet werden konnten. Nach verschiedenen Ein- und Ausschlusskriterien wurden schliesslich sieben Studien und zwei Reviews ausgewählt und mit der Methode der qualitativen Inhaltsanalyse bearbeitet. In der anschliessenden Diskussion der Ergebnisse fliessen sowohl Resultate aus dem ersten als auch aus dem zweiten Teil ein. Die Ergebnisse zeigen, dass die Interaktion der Lehrperson mit den Kindern einen Einfluss auf das Verhalten der Kinder hat. Wie die Lehrperson interagiert und ihren Unterricht gestaltet, wird unter anderem von ihrer Haltung beeinflusst. Mehr Wissen zu Themen der Integration und zum Umgang mit Verhaltensstörungen können die Haltung der Lehrperson positiv beeinflussen. Daher werden Schulische Heilpädagoginnen ermutigt, den Wissenstransfer aus der Forschung insbesondere auch in die Turnhallen zu unterstützen. Zur methodisch-didaktischen Gestaltung von integrativem Sport-unterricht und zur Förderung von emotionalen und sozialen Kompetenzen werden konkrete Empfehlungen abgegeben.

“Europe and the money muddle” revisited
Creators: name: TRIFFIN, R.
Publisher: name: PSL Quarterly Review
Year: 2014
Subjects: subject: Europe, international monetary system, inflation, unemployment, reform
subject: E42, E31, E24

description: The inability of European governments to negotiate the long overdue reform of an anachronistic international monetary system finally brought about its total collapse, and the “new economic policy” launched in 1971 by the Nixon Administration has certainly failed so far to remedy either the world inflation or the world recession and unemployment. The present article looks at how the world economy got to this point and how it can get out. The author first considers the role that non-monetary causes, national monetary permissiveness, international monetary institutions and policies, and the abdication of responsibility to the private market have played. Possible solutions to the principal economic problems (inflation, unemployment, balance of payments disequilibria and income disparity) are then identified in international monetary reform and exchange rate interventions. Finally the author assess the challenges that face the European Community going forward. JEL: E42, E31, E24

description: Kochunterricht ist eine sehr vielschichtige, komplexe und verbindende Unterrichtseinheit, da dabei auf eine lebenspraktische Art und Weise zahlreiche Fähigkeiten und Kompetenzen – von Mathematik über Sprache, von motorischen Fähigkeiten über Umgang mit Anforderungen, von sozialen Kompetenzen, beruflicher und lebenspraktischer Orientierung über Ernährung bis hin zu kulturellen Inhalten – vermittelt, gefördert und miteinander in Beziehung gesetzt werden können. Als Erweiterung meines Praxisprojekts zum Thema «Förderung der Handlungsfähigkeit im Kochunter-richt», in welchem ich konkrete Kochunterrichtslektionen in einer heilpädagogischen Mittelstufenklasse geplant, gestaltet und durchgeführt habe, werden in dieser Masterarbeit aus den gewonnenen Erkennt-nissen drei beispielhafte Bildungspläne nach Hollenweger und Bühler (2019) auf unterschiedlichen Lernniveaustufen für den Kochunterricht entwickelt und vorgestellt. Grundlage solcher Bildungspläne bilden einerseits die Lernniveaustufen der einzelnen Schülerinnen und Schüler, andererseits der Kompetenz-katalog des Lehrplans 21, welcher anhand von Befähigungsbereichen für Lernende mit komplexen Be-einträchtigungen erweitert und durch Elementarisierung, Kontextualisierung und Personalisierung indivi-duell den individuellen Voraussetzungen angepasst wird. Ziel dieser Masterarbeit ist es aufzuzeigen, welche Kompetenzen des Lehrplans 21 bei der Kochunter-richtsplanung alle berücksichtigt werden können und wie sich daraus Bildungspläne fürs Kochen gestal-ten lassen. Ergebnis dieser Auseinandersetzung bilden 3 konkrete Bildungspläne für 3 Schülerinnen und Schüler auf unterschiedlichen Lernniveaustufen. In der Evaluation werden zum Abschluss die erarbeite-ten Bildungspläne miteinander verglichen sowie die Vorgehensweise, der Kompetenzkatalog des Lehrplans 21 und die Bedeutung der Ergebnisse für die Praxis reflektiert.
