description: The conception of “floral strips” is a strategy to provide more and different food sources for pollinators. The impact of “homogeneous” Phacelia tanacetifolia (“Phacelia”) and “heterogeneous” (flower mix) food sources on the enzyme activity of bumblebees (Bombus terrestris) and honeybees (Apis mellifera) under urban conditions has not been reported. Organisms responding to challenging environmental conditions are known to exhibit increases in oxidative stress parameters which in turn affect both physiological and metabolic parameters. A field study was conducted in Berlin-Dahlem, Germany, using the response of the “marker” enzyme superoxide dismutase (SOD) on food sources for assessment. SOD data is also shown from the wild bee Megachile rotundata (Fabricius 1787), obtained from three different locations in the federal state Brandenburg, Germany. The results demonstrate that the enzyme activity of SOD significantly increased in bumblebees visiting the flower mix compared to the Phacelia. The experimental approach had individual effects at the level of the species, bumblebees and honeybees, respectively. The activity of the biomarker SOD could be successfully used to assess the effects of the compositions of homogeneous and heterogeneous flower fields.

description: Groundwater is the largest freshwater reservoir in the whole world. Α large proportion of consumers’ needs for water is covered by groundwater. So, it is necessary to protect the quantity and the quality of underground water reserves, through a series of measures. In order to ensure good quality of ground water resources, an important measure is definition of well protection zones. In these zones certain land uses are restricted or completely forbidden, in order to avoid pollution of groundwater resources. This Diploma Thesis investigates the location of new monitoring wells in order to inform us, six months earlier, the advent of pollution in each of existing production wells. The respective code has been developed in C++.

description: Roughness determines many functional properties of surfaces, such as adhesion, friction, and (thermal and electrical) contact conductance. Recent analytical models and simulations enable quantitative prediction of these properties from knowledge of the power spectral density (PSD) of the surface topography. The utility of the PSD is that it contains statistical information that is unbiased by the particular scan size and pixel resolution chosen by the researcher. In this article, we first review the mathematical definition of the PSD, including the one- and two-dimensional cases, and common variations of each. We then discuss strategies for reconstructing an accurate PSD of a surface using topography measurements at different size scales. Finally, we discuss detecting and mitigating artifacts at the smallest scales, and computing upper/lower bounds on functional properties obtained from models. We accompany our discussion with virtual measurements on computer-generated surfaces. This discussion summarizes how to analyze topography measurements to reconstruct a reliable PSD. Analytical models demonstrate the potential for tuning functional properties by rationally tailoring surface topography - however, this potential can only be achieved through the accurate, quantitative reconstruction of the power spectral density of real-world surfaces.

Στην έρευνα έλαβαν μέρος 10 νέοι υγιείς άνδρες ηλικίας 24.1 ± 2.2 ετών. Οι συμμετέχοντες, αφού προετοιμάστηκαν, τοποθετήθηκαν σε πάγκο, σε ύπτια θέση, με τα πόδια τους τεντωμένα και σε χαλάρωση. Πριν την έναρξη της άσκησης μετρήθηκαν με δύο υπερήχους για να βρεθεί το μυϊκό πάχος στην ηρεμία. Μετά το πέρας του πρωτοκόλλου και στο πρώτο λεπτό, τοποθετήθηκαν με τον ίδιο τρόπο στον πάγκο για επαναμέτρηση. Μετά τη πρώτη μέτρηση στους υπερήχους ακολούθησε η μέτρηση στο ισοκινητικό δυναμόμετρο. Αφότου είχαν τοποθετηθεί σε σωστή ανατομική θέση και είχαν τοποθετηθεί σωστά και τα ηλεκτρόδια του ηλεκτρομυογράφου, ακολούθησε το πρωτόκολλο άσκησης. Εκτέλεσαν 50 μέγιστες σύγκεντρες ισοκινητικές συσπάσεις, με γωνιακή ταχύτητα στις 120ο . Τα αποτελέσματα έδειξαν ότι το πάχος των δύο μυών αυξήθηκε με παρόμοιο τρόπο μετά την εφαρμογή του πρωτοκόλλου. Επιπλέον, στο σημείο 40% φάνηκε να εμφανίζεται στατιστικά η μικρότερη αύξηση (p < 0.05), ενώ τα σημεία 60% και 80% δεν εμφάνισαν στατιστικά σημαντικές διαφορές (p > 0.05). Τα συμπεράσματα αυτά μπορούν να χρησιμοποιηθούν σε προγράμματα προπόνησης ή αποκατάστασης που στόχο θα έχουν τη στοχευμένη μυϊκή υπερτροφία του τετρακεφάλου μηριαίου μυός
description: The aim of the present study was to study the differences in the thickness of vastus lateralis and vastus medialis, after a fatigue protocol, at the points 40% - 60% - 80% of the total length of the femur. The study involved 10 young healthy men aged 24.1 ± 2.2 years. The participants, after preparation, were placed on a bench, in a supine position, with their legs outstretched and relaxed. Before the start of the exercise, they were measured with two ultrasounds to find the muscle thickness at rest. After the end of the protocol and in the first minute, they were placed in the same way on the bench for recounting. The first ultrasound measurement was followed by the measurement on the isokinetic dynamometer. After the electromyograph electrodes were placed in the correct anatomical position and the electrodes were placed correctly, the exercise protocol was followed. They performed 50 maximum concentrated isokinetic contractions, with an angular velocity at 120ο. The results showed that the thickness of the two muscles increased in a similar way after the application of the protocol. In addition, the 40% point statistically showed the smallest increase (p 0.05). These findings can be used in training or rehabilitation programs that target the quadriceps femoris muscle growth

description: We present the results of a new spectroscopic survey for dusty intervening absorption systems, particularly damped Ly$α$ absorbers (DLAs), towards reddened quasars. The candidate quasars are selected from mid-infrared photometry from the Wide-field Infrared Survey Explorer combined with optical and near-infrared photometry. Out of 1073 candidates, we secure low-resolution spectra for 108 using the Nordic Optical Telescope on La Palma, Spain. Based on the spectra, we are able to classify 100 of the 108 targets as quasars. A large fraction (50 %) is observed to have broad absorption lines (BALs). Moreover, we find 6 quasars with strange breaks in their spectra, which are not consistent with regular dust reddening. Using template fitting we infer the amount of reddening along each line of sight ranging from A(V)$\approx$0.1 mag to 1.2 mag (assuming an SMC extinction curve). In four cases, the reddening is consistent with dust exhibiting the 2175Å feature caused by an intervening absorber, and for two of these, a MgII absorption system is observed at the best-fit absorption redshift. In the rest of the cases, the reddening is most likely intrinsic to the quasar. We observe no evidence for dusty DLAs in this survey. However, the large fraction of BAL quasars hampers the detection of absorption systems. Out of the 50 non-BAL quasars only 28 have sufficiently high redshift to detect Ly$α$ in absorption.

description: Witten indices and partition functions are computed for abelian 6d tensor and hypermultiplets on $\mathbb{R}\times S^5$ in Lorentzian signature in an R gauge field background which preserves some supersymmetry. We consider a generic supersymmetric squashing that also admits squashing of the Hopf fiber. Wick rotation to Euclidean M5 brane amounts to Wick rotation of squashing parameters and the hypermultiplet mass parameter. We compute Casimir energies for tensor and hypermultiplets separately for general squashing, and match these with the corresponding gravitational anomaly polynomials. We extract Witten indices on $\mathbb{R}\times \mathbb{CP}^2$ and find that this is zero, again matching with the vanishing anomaly polynomial on an odd dimensional space.

Sampling-based model order reduction for stochastic differential equations driven by fractional Brownian motion

Subjects: subject: 510

description: In this paper, we study large-scale linear fractional stochastic systems representing, e.g., spatially discretized stochastic partial differential equations (SPDEs) driven by fractional Brownian motion (fBm) with Hurst parameter H > ½. Such equations are more realistic in modeling real-world phenomena in comparison to frameworks not capturing memory effects. To the best of our knowledge, dimension reduction schemes for such settings have not been studied so far. In this work, we investigate empirical reduced order methods that are either based on snapshots (e.g. proper orthogonal decomposition) or on approximated Gramians. In each case, dominant subspaces are learned from data. Such model reduction techniques are introduced and analyzed for stochastic systems with fractional noise and later applied to spatially discretized SPDEs driven by fBm in order to reduce the computational cost arising from both the high dimension of the considered stochastic system and a large number of required Monte Carlo runs. We validate our proposed techniques with numerical experiments for some large-scale stochastic differential equations driven by fBm.

description: This thesis presents five essays that compare rational-inattentiveness models and sticky-information models with rational-expectations models in several respects. Assumptions about rationality in both types of models are tested for, implications derived from rational-inattentiveness models are investigated, models' accuracies are evaluated, predicted information acquisition behavior is tested, and assumptions about information costs are inspected. Chapter 2 presents an empirical test of the two different concepts of rationality underlying rational-expectations models and rational-inattentiveness models. The results support the concept used in rational-inattentiveness models. Chapter 3 tests implications of rational-inattentiveness models with respect to forecasting macroeconomic variables. Rational-inattentiveness models predict a negative correlation between the amount of news and the forecast deviation. A negative correlation between news coverage and forecast deviation occurs empirically for inflation whereas a positive correlation is found in the context of unemployment. A comparison between the sticky-information and the sticky-price Phillips curve is made in Chapter 4. The overall results of the empirical performances allow no clear distinction between the two concepts. However, if one is predominantly interested in matching unconditional moments of inflation dynamics, sticky prices should be used. Researchers who focus on co-movements of inflation with demand will obtain better results applying sticky information. In Chapters 5 and 6, the information acquisition behavior predicted by rational-inattentiveness models and the assumptions about information costs in these models and in rational-expectations models are tested in an experimental environment. The overall results in Chapter 5 indicate that the prediction of information acquisition derived from rational-inattentiveness models cannot be rejected. The analysis in Chapter 6 shows that assumption about information costs of the rational-inattentiveness models cannot be rejected in contrast to the assumptions in rational-expectations models.

description: This is a ribbon map of the Mekong river, inspired by 19th century river length comparisons and the Father of Waters, a ribbon map for Mississippi steam boat captains. The map "straightens" the Mekong river into an elongated map by cutting and re-orienting the river course to fit within the bounds. The map starts from the river mouth in Vietnam at the bottom of the map, and reaches the source of the river in Tibet at the top. It contains many interesting features and pieces of information on the culture and geography of the region. There are two versions of the map with small differences. The main difference between them is size and the inclusion of an elevation model. Version 1 is approximately 550 cm in length and 19 cm in length, and does not contain an elevation model. Version 2 is 650mm in length and 40cm in width, and shows an elevation model along the river. Note that Adobe Acrobat reader is not able to open the larger version 2 of the map, because it exceeds the maximum page size. Other PDF-readers do work, however.  If you have any comments on the contents, or wish to add something, please let me know at marko@markokallio.fi. This is the first "finished" version but I'm keen to keep working with it.

description: 1. Biodiversity is an important component of natural ecosystems, with higher species richness often correlating with an increase in ecosystem productivity. Yet, this relationship varies substantially across environments, typically becoming less pronounced at high levels of species richness. However, species richness alone cannot reflect all important properties of a community, including community evenness, which may mediate the relationship between biodiversity and productivity. If the evenness of a community correlates negatively with richness across forests globally, then a greater number of species may not always increase overall diversity and productivity of the system. Theoretical work and local empirical studies have shown that the effect of evenness on ecosystem functioning may be especially strong at high richness levels, yet the consistency of this remains untested at a global scale. 2. Here, we used a dataset of forests from across the globe, which includes composition, biomass accumulation and net primary productivity, to explore whether productivity correlates with community evenness and richness in a way that evenness appears to buffer the effect of richness. Specifically, we evaluated whether low levels of evenness in speciose communities correlate with the attenuation of the richness–productivity relationship. 3. We found that tree species richness and evenness are negatively correlated across forests globally, with highly speciose forests typically comprising a few dominant and many rare species. Furthermore, we found that the correlation between diversity and productivity changes with evenness: at low richness, uneven communities are more productive, while at high richness, even communities are more productive. 4. Synthesis. Collectively, these results demonstrate that evenness is an integral component of the relationship between biodiversity and productivity, and that the attenuating effect of richness on forest productivity might be partly explained by low evenness in speciose communities. Productivity generally increases with species richness, until reduced evenness limits the overall increases in community diversity. Our research suggests that evenness is a fundamental component of biodiversity–ecosystem function relationships, and is of critical importance for guiding conservation and sustainable ecosystem management decisions.

description: Unter dem Namen „Van Selow“ werden im Kunsthandel solche Objekte angeboten, die in der von Johann Michael van Selow im Jahr 1756 gegründeten und zunächst von ihm, dann von Nachfolgern geleiteten Braunschweiger Manufaktur hergestellt wurden. Für die von Van Selow als neue, eigene Erfindung bezeichnete Technik in der Verwendung von Glasperlen lassen sich weder direkte Vorbilder noch Weiterentwicklungen finden. Dies macht die nur etwa zwei Jahrzehnte lang existierende Manufaktur einerseits zu einem räumlich und zeitlich stark begrenzten Phänomen, während andererseits ihre Produkte damals wie heute internationale Verbreitung fanden. Die hohen Preise, die heutzutage bei internationalen Auktionen erzielt werden, etablieren Van Selow als wertvolle Marke und die Objekte der Manufaktur als gefragte Raritäten. Die vorliegende Arbeit beleuchtet das Schaffen der Manufaktur von verschiedenen Seiten. Neben einer kunsthistorischen Betrachtung der stilistischen Einflüsse auf die Formenwelt Van Selows, stellt diese Arbeit die erste umfassende Einordnung der Glasperlenmosaike in Kittmasse in das vielfältige Kunstschaffen des 18. Jahrhunderts dar. Hierbei werden kulturhistorische Aspekte wie die Nutzung oder die Bedeutung der Farbigkeit ebenso untersucht wie eine Vielzahl der verwendeten Materialien und ihr spezifischer Einsatz an diesen außergewöhnlichen Objekten. Auch die Frage nach Authentizität wird behandelt, indem traditionelle Zuschreibungen hinterfragt und Kunstwerke unter anderem aus England und Dänemark diskutiert werden, die bisher in diesem Zusammenhang kaum Beachtung fanden. Eine Kombination aus stilistischen Eigenheiten und technologischen Besonderheiten liefert die Kriterien für Zuweisungen zum unsignierten Œvre dieses vielseitigen Künstlers und geschickten Unternehmers. So vielgestaltig die Objekte der so genannten „Corallenfabric“ Van Selows sind, so divers und interdisziplinär sind auch die hier erstmals in dieser umfassenden Form vorgelegten Forschungsansätze, die zu einem besseren Verständnis des Künstlers und seiner Schaffensweise sowie zu einer Eingliederung dieser speziellen Objektgruppe in das Kunsthandwerk des 18. Jahrhunderts beitragen können. Auf diesen Ergebnissen aufbauend wird die bisher in der Forschung unerwähnt gebliebene Rezeption der Werke Van Selows sowohl zur Zeit ihrer Entstehung als auch bis zum heutigen Tag beleuchtet. Diese Arbeit leistet einen Beitrag dazu, das bislang ausschließlich als Kuriosität wahrgenommene Glasperlenmosaik in einen größeren Zusammenhang zu stellen und ihm einen Rahmen zu geben.

description: An improved finite difference method with compact correction term is proposed to solve the Poisson equations. The compact correction term is developed by a coupled high-order compact and low-order classical finite difference formulations. The numerical solutions obtained by the classical finite difference method are considered as fundamental solutions with lower accuracy, whereas compact correction term is added into source term of classical discrete formulation to improve the accuracy of numerical solutions. The proposed method can be extended from two- to multi-dimensional cases straightforwardly. Numerical experiments are carried out to verify the accuracy and efficiency of this method.

description: A mathematical modeling was done to determine the demographic impact ofHIY/AIDS epidemic in Addis Ababa. It was found that:- a) the adult HIY prevalence will reach a plateau level of [0.78% in the year 2001 and then declines to 10.28% in the year 2004. b) AIDS will slow the decline in infant mortality rate and under 5 mortality rates and will increase crude death rate and lowers the life expectancy at birth. c) AIDS will reduce the size ofthe Addis Ababa population by about 160,000 people in the year 2004, but will not stop or make its growth negative. d) AIDS will also reduce fertility but, e) it will not worsen the traditional dependency ratio (i.e., the population under age 15 and over age 64, as a proportion of the population of age 15-64). Similar trends were reported by studies conducted in other subSaharan African countries. Based on the above findings, preventive measures such as STD control, condom promotion, IEC and blood screening, approaching the problem multisectorally, incorporating the HIY/ AIDS epidemic in the demographic projection, and establishing HIY/AIDS data base were recommended.

description: Kinder mit Verhaltensstörungen entsprechen nicht den Idealvorstellungen eines sogenannt normalen Schülers und sind darum mit vielen Vorurteilen und negativen Stigmatisierungen konfrontiert, was ihren (Schul-) Alltag oftmals erschwert. Es fällt ihnen schwer, sich an Regeln und Abmachungen zu halten, sie sind oft laut und stören. Der Umgang mit solchen Kindern stellt eine der grössten Herausforderungen der Schule heute dar; Praxisbeispiele und Erfahrungen zeigen dies deutlich. Die schulische Integration von Kindern mit Verhaltensstörungen ist unbestritten. Auf Interessen und Wohlergehen des Kindes wird besonders geachtet. Durch ein quantitatives und qualitatives Forschungsvorgehen wurden Einflussfaktoren und Gelingensbedingungen der schulischen Integration von Kindern mit Verhaltensstörungen auf der Unterstufe ermittelt. Dabei stellte sich heraus, dass sowohl für Lehrpersonen wie auch für Schulische Heilpädagogen die Beziehung zwischen ihnen und dem Schüler, eine positive Einstellung gegenüber der Integration allgemein und gutes Classroom-Management im Zentrum steht.
Efficiency Trends and Challenges in MENA Financial Markets

description: A cornerstone of modern financial theory, with many theoretical and practical implications, the theory of the informational efficiency of financial markets plays an important role in the day-to-day practice of market finance.

Developed by Eugene Fama in 1965, this theory has been the subject of several empirical tests in different financial markets. Many studies have attempted to verify the truth or falsity of this hypothesis in different types of markets, often developed; however, few studies have focused on developing markets, especially those in the MENA region.

The aim of our study is to verify this hypothesis in this region, by analyzing the time series of daily logarithmic returns of the main stock market indices in a sample of 7 countries with different characteristics, using a range of econometric tests including normality and serial autocorrelation tests. We then attempt to explore the factors likely to explain the efficiency or inefficiency of these markets, using probit modeling.

description: An intervention study to assess the impact of participative goal setting and feedback on the staff of health service facilities was conducted in three districts of East Shewa Zone over a period of three months, from October to December, 1993. A pretested questionnaire was administered twice to measure the motivational force score (MFS) for seven selected primary health care (PHC) activities. The correlation of these scores with the performance of each activity was calculated to determine their association. The study included a total of 12 health institutions: six in the intervention group and six in the control group with 48 and 46 health workers respectively. Health institutions in the intervention group participatively set goals and developed strategies to attain them for the selected PHC activities for three months (October to December, 1993). were also conducted during this Feedback sessions period. Health insti tutions in the control group had assigned goals without feedback but conducted clinical sessions in the same period. Comparison of the pre- and post-intervention period mean changes in coverage for the selected PHC variables together revealed a significant difference (t : 2.28, p < 0.05) between the intervention and control groups, and a positive association was found between the participatively set goal levels ' and mean change in coverage of the variables ( r = 0.762, 95% CI = 0.642 to 0.882) in the intervention group . Comparison of both the first and second MFS for the variables between the intervention and control groups showed significantly higher MFS in the intervention group (t = 2.49 , p < 0.05 and t = 4.53, p < 0 . 001) than in the control group. between MFSs But no significant association was found and mean changes in coverage of the variables in both study groups. These findings are suggestive of the potential usefulness of participative goal-setting and feedback acti vi ties to improve organizational performance . Participatory goal-setting with feedback appears to have both cognitive and motivational impact on the staff of health service facilities. On the other hand, higher expectancy or valence for PHC activiti es by health workers alone was found not to lead to increased performance .
Rotating Stars from Kepler Observed with Gaia DR1

description: Astrometric data from the recent Gaia Data Release 1 has been matched against the sample of stars from Kepler with known rotation periods. A total of 1,299 bright rotating stars were recovered from the subset of Gaia sources with good astrometric solutions, most with temperatures hotter than 5000 K. From these sources, 894 were selected as lying near the main sequence using their absolute G-band magnitudes. These main sequence stars show a bimodality in their rotation period distribution, centered roughly around a 600 Myr rotation-isochrone. This feature matches the bimodal period distribution found in cooler stars with Kepler, but was previously undetected for solar-type stars due to sample contamination by subgiants. A tenuous connection between the rotation period and total proper motion is found, suggesting the period bimodality is due to the age distribution of stars within ~300pc of the Sun, rather than a phase of rapid angular momentum loss. This work emphasizes the unique power for understanding stellar populations by combining temporal monitoring from Kepler with astrometric data from Gaia.

title: Understanding water chemistry in biofilters using chemometric methods

Publisher: name: University of Glasgow

description: Biological activated carbon filtration operating in slow flowing mode is a compromise between slow sand filtration and rapid-rate biological activated carbon filtration. It brings together the benefits of both systems: good control of microbial pathogens and dissolved organic matter removal. In this thesis the change in water chemistry in such biofilters was studied as a possible alternative for small-scale decentralised water treatment in Scotland. Change in chemical water quality was monitored in the influent, effluent, and pore water of labscale biofilters of varying lengths. Also, the effect of pore water chemistry on carbon processing by microbial communities from various filter depths was studied by batch experiment. Finally the effect of spatial and temporal water quality variation in Scotland on biofilter performance was studied via a metadata study. Results showed that dissolved organic matter was removed via multistage adsorption with filter length having a positive impact on the removal efficiency in apparent steady state. Applying the biofilters to other Scottish fresh waters with lower DOM concentrations will increase their performance. Within the filters, different ecological niches were formed. The community at the top processed the easily available low molecular weight acids, the community at the bottom was able to degrade the more recalcitrant humic substances. This indicates that specific microbes inhabit this bottom niche and are able to survive on the limited choice of DOM species. These research findings contribute to further optimisation of the biofilter design and for the scientific community to further understand biofilter stratification and its impact on DOM removal.

description: We investigate the short interval expansion of the Rényi entropy for two-dimensional conformal field theory (CFT) on a torus. We require the length of the interval $\ell$ to be small with respect to the spatial and temporal sizes of the torus. The operator product expansion of the twist operators allows us to compute the short interval expansion of the Rényi entropy at any temperature. In particular, we pay special attention to the large $c$ CFTs dual to the AdS$_3$ gravity and its cousins. At both low and high temperature limits, we read the Rényi entropies to order $\ell^6$, and find good agreements with holographic results. Moreover, the expansion allows us to read $1/c$ contribution, which is hard to get by expanding the thermal density matrix. We generalize the study to the case with the chemical potential as well.

description: There is an understanding that effective HJV / AIDS prevention programs should be based on the models and theories of behavior change so that the programs can be designed to change those factors which lead to the Lmdesirable risk behaviors and maintain the desirable once. With the objectives of determining HIV / AIDS related sex ual behaviors and assessing their relation with variables derived from the classical models of health behavior, a study using a pre-tested selfadministered questiOlUlaire to collect information from a random sample of six hundred and sixty high school students was conducted in Jimma town on March 2000. Among the high school students 6.7% of female students and I 1.2% of male students were found to have involved in sexual activity with worst lifetime sexual behavior index. Of the sexually active students the rate of unprotected sexual intercourse and intercourse with more than one sexual pminer in the past year were 81. 7% and 19.3%, respectively. There is a significant gender difference in HIV -related risk sexual act and belief-intention factors. Higher propOliions of males were involved in these high-risk sexual acts. Independent and significant predictors of intention to limit sexual paltners were perceived barriers and normative belief for female students and normative belief and perceived behavioral control for male students. On the other hand, knowing an individual who has/had HIV / AIDS, motivation to comply, normative belief, and perceived behavioral conh'ol for females; while only perceived susceptibility and perceived behavioral control for males independently and significantly predicted the intention to use condom in the next sexual intercourse. It was concluded that high school students are at risk of HIV infection because of the high-risk behaviors they have. Pattems of gender difference are found and theOly-driven and gender appropriate educational interventions and researches are recommended. ii

Masterarbeit

description: Diese Forschungsarbeit widmet sich der Frage, wie exekutive Funktionen von Schüler/innen in der Arbeit mit Wochenplan gefördert werden können, so dass insbesondere auch Schüler/innen mit besonderem Förderbedarf in diesem Bereich davon profitieren. Sie zeigt auf, wie die Ziele und Anforderungen des Wochenplanunterrichts mit exekutiven Funktionen wie Planen, Organisation (innere und äussere), Selbstregulation der Aufmerksamkeit, Selbstregulation des Affekts, Metakognition u.a. zusammenhängen. Sie erläutert Kriterien für einen Wochenplanunterricht, welcher exekutive Funktionen tatsächlich fördert und zeigt insbesondere Wichtigkeit und Prinzipien effektiver Strategievermittlung auf. Vor diesem theoretischen Hintergrund wurde mittels Interviews und einer qualitativen Inhaltsanalyse untersucht, was Lehrpersonen in ihrem Wochenplanunterricht zur Förderung exekutiver Funktionen tun. Ideen aus der Praxis wurden mit Handlungskonzepten aus der Literatur verknüpft und in einer Ideensammlung (s. Beilage) zusammengestellt. Ergebnisse aus den Befragungen deuten darauf hin, dass das Thema der exekutiven Funktionen und deren gezielte Förderung insbesondere im Bereich der Selbstregulation in der Praxis noch wenig Fuss gefasst haben. Die Ideensammlung zur Förderung exekutiver Funktionen im Wochenplanunterricht zeigt daher praxisnah und konkret auf, wie exekutive Funktionen im Rahmen der Wochenplanarbeit gefördert werden können.
