  abstract  = {Turkey has been severely affected by many natural hazards, in particular earthquakes and floods. Although there is a large body of literature on earthquake hazards and risks in Turkey, comparatively little is known about flood hazards and risks. Therefore, with this study it is aimed to investigate flood patterns, societal and economic impacts of flood hazards in Turkey, as well as providing a comparative overview of the temporal and spatial distribution of flood losses by analysing EM-DAT (Emergency Events Database) and TABB (Turkey Disaster Data Base) databases on disaster losses throughout Turkey for the years 1960-2014. The comparison of these two databases reveals big mismatches of the flood data, e.g. the reported number of events, number of affected people and economic loss, differ dramatically. With this paper, it has been explored reasons for mismatches. Biases and fallacies for loss data in the two databases has been discussed as well. Since loss data collection is gaining more and more attention, e.g. in the Sendai Framework for Disaster Risk Reduction 2015-2030 (SFDRR), the study could offer a base-work for developing guidelines and procedures on how to standardize loss databases and implement across the other hazard events, as well as substantial insights for flood risk mitigation and adaptation studies in Turkey and will offer valuable insights for other (European) countries.},

  abstract  = {Since the economic crisis in 2008, European youth unemployment rates have been persistently high at around 20\% on average. The majority of European countries spends significant resources each year on active labor market programs (ALMP) with the aim of improving the integration prospects of struggling youths. Among the most common programs used are training courses, job search assistance and monitoring, subsidized employment, and public work programs. For policy makers, it is of upmost importance to know which of these programs work and which are able to achieve the intended goals - may it be the integration into the first labor market or further education. Based on a detailed assessment of the particularities of the youth labor market situation, we discuss the pros and cons of different ALMP types. We then provide a comprehensive survey of the recent evidence on the effectiveness of these ALMP for youth in Europe, highlighting factors that seem to promote or impede their effectiveness in practice. Overall, the findings with respect to employment outcomes are only partly promising. While job search assistance (with and without monitoring) results in overwhelmingly positive effects, we find more mixed effects for training and wage subsidies, whereas the effects for public work programs are clearly negative. The evidence on the impact of ALMP on furthering education participation as well as employment quality is scarce, requiring additional research and allowing only limited conclusions so far.},

We analyze in detail appearance and stability properties of this state in possibly the simplest setup of a biharmonic Kuramoto-Daido phase model as well as demonstrate the effect in limit-cycle relaxational Rayleigh oscillators. Such a regime extends the notion of splay state from a uniform distribution of phases to an oscillating one. Suitable collective observables such as the Kuramoto order parameter allow detecting the presence of an inhomogeneous distribution. The characteristic and most peculiar property of self-consistent partial synchrony is the difference between the frequency of single units and that of the macroscopic field.},

  abstract  = {Low Earth orbiting geomagnetic satellite missions, such as the Swarm satellite mission, are the only means to monitor and investigate ionospheric currents on a global scale and to make in situ measurements of F region currents. High-precision geomagnetic satellite missions are also able to detect ionospheric currents during quiet-time geomagnetic conditions that only have few nanotesla amplitudes in the magnetic field. An efficient method to isolate the ionospheric signals from satellite magnetic field measurements has been the use of residuals between the observations and predictions from empirical geomagnetic models for other geomagnetic sources, such as the core and lithospheric field or signals from the quiet-time magnetospheric currents. This study aims at highlighting the importance of high-resolution magnetic field models that are able to predict the lithospheric field and that consider the quiet-time magnetosphere for reliably isolating signatures from ionospheric currents during geomagnetically quiet times. The effects on the detection of ionospheric currents arising from neglecting the lithospheric and magnetospheric sources are discussed on the example of four Swarm orbits during very quiet times. The respective orbits show a broad range of typical scenarios, such as strong and weak ionospheric signal (during day- and nighttime, respectively) superimposed over strong and weak lithospheric signals. If predictions from the lithosphere or magnetosphere are not properly considered, the amplitude of the ionospheric currents, such as the midlatitude Sq currents or the equatorial electrojet (EEJ), is modulated by 10-15 \% in the examples shown. An analysis from several orbits above the African sector, where the lithospheric field is significant, showed that the peak value of the signatures of the EEJ is in error by 5 \% in average when lithospheric contributions are not considered, which is in the range of uncertainties of present empirical models of the EEJ.},

In general, limited numbers of individuals have been released to establish new populations. To evaluate the effects of reintroductions on the genetic status of lynx populations we used 12 microsatellite loci to study lynx populations in the Bohemian-Bavarian and Vosges-Palatinian forests. Compared with autochthonous lynx populations, these two reintroduced populations displayed reduced genetic diversity, particularly the Vosges-Palatinian population. Our genetic data provide further evidence to support the status of 'endangered' and 'critically endangered' for the Bohemian-Bavarian and Vosges-Palatinian populations, respectively. Regarding conservation management, we highlight the need to limit poaching, and advocate additional translocations to bolster genetic variability.},

  abstract  = {The current study investigates an interaction between numbers and physical size (i.e. size congruity) in visual search. In three experiments, participants had to detect a physically large (or small) target item among physically small (or large) distractors in a search task comprising single-digit numbers. The relative numerical size of the digits was varied, such that the target item was either among the numerically large or small numbers in the search display and the relation between numerical and physical size was either congruent or incongruent. Perceptual differences of the stimuli were controlled by a condition in which participants had to search for a differently coloured target item with the same physical size and by the usage of LCD-style numbers that were matched in visual similarity by shape transformations. The results of all three experiments consistently revealed that detecting a physically large target item is significantly faster when the numerical size of the target item is large as well (congruent), compared to when it is small (incongruent). This novel finding of a size congruity effect in visual search demonstrates an interaction between numerical and physical size in an experimental setting beyond typically used binary comparison tasks, and provides important new evidence for the notion of shared cognitive codes for numbers and sensorimotor magnitudes. Theoretical consequences for recent models on attention, magnitude representation and their interactions are discussed.},

Zahlreiche Veranstaltungen und Publikationen zum Jubeljahr beleuchten, wie sich die Universit{\"a}t seit ihrer Gr{\"u}ndung am 15. Juli 1991 entwickelt hat. Auch die Redaktion von Portal Alumni will dieses Vierteljahrhundert in den Blick nehmen und zwar aus der Perspektive der Studierenden und Alumni. Wir haben uns gefragt: Wie hat sich das Studium an der Universit{\"a}t Potsdam in der Vergangenheit ge{\"a}ndert? Was ist den Studierenden heute wichtig, was waren wichtige Themen vor zehn oder zwanzig Jahren? Welche Erinnerungen haben Alumni an ihre Hochschulzeit? In diesem Heft lassen wir Alumni zu Wort kommen, die zu unterschiedlichen Zeiten an der Universit{\"a}t studiert haben und die f{\"u}r uns einen Blick zur{\"u}ck werfen auf ihre Generation. Mit dabei ist etwa Stefan Uhlmann, der sein Studium kurz vor dem Wendeherbst aufgenommen hatte. Sein erstes Semester war noch gepr{\"a}gt von sozialer Sicherheit: Der Staat zahlte den monatlichen studentischen Unterhalt von 200 Mark, die Universit{\"a}t stellte den Wohnheimplatz. Selbst der Arbeitsplatz war nach den Gesetzen der Planwirtschaft sicher. Wenige Monate sp{\"a}ter war alles anders: Die Inhalte aller Studieng{\"a}nge wurden auf den Pr{\"u}fstand gestellt, alle Rahmenbedingungen neu gestaltet, die gesamte Gesellschaft und damit auch der Arbeitsmarkt waren im Umbruch. Zwischen der Generation von Stefan Uhlmann und der der jungen Bachelorabsolventin Friederike Bath liegen 25 Jahre Universit{\"a}tsgeschichte. Eine Zeit, in der sich Lehre und Studium gewandelt haben. Der Einf{\"u}hrung von einer Studienordnung nach bundesdeutschem Recht folgte in der Jahrtausendwende die Bologna-Reform, die nicht nur das Studieren ver{\"a}ndert hat. Sie hat auch einen Wertewandel mit sich gebracht, den der Sozialisationswissenschaftler Wilfried Schubarth in dieser Ausgabe beschreibt.},

  abstract  = {We analyzed the population genetic pattern of 12 fragmented Geropogon hybridus ecological range edge populations in Israel along a steep precipitation gradient. In the investigation area (45 x 20 km(2)), the annual mean precipitation changes rapidly from 450 mm in the north (Mediterranean-influenced climate zone) to 300 mm in the south (semiarid climate zone) without significant temperature changes. Our analysis (91 individuals, 12 populations, 123 polymorphic loci) revealed strongly structured populations (AMOVA I broken vertical bar(ST) = 0.35; P < 0.001); however, differentiation did not change gradually toward range edge. IBD was significant (Mantel test r = 0.81; P = 0.001) and derived from sharply divided groups between the northernmost populations and the others further south, due to dispersal or environmental limitations. This was corroborated by the PCA and STRUCTURE analyses. IBD and IBE were significant despite the micro-geographic scale of the study area, which indicates that reduced precipitation toward range edge leads to population genetic divergence. However, this pattern diminished when the hypothesized gene flow barrier was taken into account. Applying the spatial analysis method revealed 11 outlier loci that were correlated to annual precipitation and, moreover, were indicative for putative precipitation-related adaptation (BAYESCAN, MCHEZA). The results suggest that even on micro-geographic scales, environmental factors play prominent roles in population divergence, genetic drift, and directional selection. The pattern is typical for strong environmental gradients, e.g., at species range edges and ecological limits, and if gene flow barriers and mosaic-like structures of fragmented habitats hamper dispersal.},

  abstract  = {Turbidity measurements are frequently implemented for the monitoring of heterogeneous chemical, physical, or biotechnological processes. However, for quantitative measurements, turbidity probes need calibration, as is requested and regulated by the ISO 7027:1999. Accordingly, a formazine suspension has to be produced. Despite this regulatory demand, no scientific publication on the stability and reproducibility of this polymerization process is available. In addition, no characterization of the optical properties of this calibration material with other optical methods had been achieved so far. Thus, in this contribution, process conditions such as temperature and concentration have been systematically investigated by turbidity probe measurements and Photon Density Wave (PDW) spectroscopy, revealing an influence on the temporal formazine formation onset. In contrast, different reaction temperatures do not lead to different scattering properties for the final formazine suspensions, but give an access to the activation energy for this condensation reaction. Based on PDW spectroscopy data, the synthesis of formazine is reproducible. However, very strong influences of the ambient conditions on the measurements of the turbidity probe have been observed, limiting its applicability. The restrictions of the turbidity probe with respect to scatterer concentration are examined on the basis of formazine and polystyrene suspensions. Compared to PDW spectroscopy data, signal saturation is observed at already low reduced scattering coefficients.},

  abstract  = {Let's be honest: even science wants to make it big, at least when it comes to discovering new knowledge. Yet if one thing belongs in the annals of successful research, it is definitely small things. Scientists have long understood that their job is to explore things that they don't see right away. Seneca once wrote, "If something is smaller than the great, this does not mean at all that it is insignificant." The smallest units of life, such as bacteria or viruses, can often have powerful effects. And again and again, (seemingly) large things must first be disassembled or reduced to small pieces in order to recognize their nature. One of the greatest secrets of our world - the atom, the smallest, if no longer indivisible, unit of chemical elements - revealed itself only by looking at its diminutive size. By no means is 'small' (German: klein) merely a counterpoint to large, at least in linguistic terms; the word comes from West Germanic klaini, which means 'fine' or 'delicate,' and is also related to the English word 'clean.' Fine and clean - certainly something worth striving for in scientific work. And a bit of attention to detail doesn't hurt either. This doesn't mean that researchers can be smallminded; they should be ready to expect the unexpected and to adjust their work accordingly. And even if they cannot attain their goals in the short term, they need staying power to keep themselves from being talked down, from giving up. Strictly speaking, research is like putting together a puzzle with tons of tiny pieces; you don't want it to end. Every discovery worthy of a Nobel Prize, every major research project, has to start with a small idea, with a tiny spark, and then the planning of the minutest details can begin. What follows is work focused on minuscule details: hours of interviews searching for the secret of the cerebellum (Latin for 'little brain'), days of field studies searching for Lilliputian forms of life, weeks of experimentation meant to render visible the microscopically tiny, months of archival research that brings odds and ends to light, or years of reading fine print. All while hunting for a big hit... This is why we've assembled a few 'little' stories about research at the University of Potsdam, under the motto: small, but look out! Nutritional scientists are working on rescuing some of the earth's smaller residents - mice - from the fate of 'lab rats' by developing alternatives to animal testing. Linguists are using innovative methods in several projects to investigate how small children learn languages. Astrophysicists in Potsdam are scanning the skies above Babelsberg for the billions of stars in the Magellan Cloud, which only seem tiny from down here. The Research Center Sanssouci, initiated by the Prussian Palaces and Gardens Foundation and the University of Potsdam, is starting small but will bring about great things for Potsdam's cultural landscape. Biologists are drilling down to the smallest building blocks of life, looking for genes in barley so that new strains with positive characteristics can be cultivated. Like we said: little things.

  abstract  = {A point is more than meets the eye. In geometry, a point is an object with zero dimensions - it is there but takes up little space. You may assume that something so small is easily overlooked. A closer look reveals that points are everywhere and play a significant role in many areas. In physics, for example, a mass point is the highest possible idealization of a body, which is the theoretical notion that the entire mass of a body is concentrated in a point, its "center of mass". Points are at the beginning (starting points), at intersections (pivot points), and at the end (final points). A point symbolizes great precision. There is a reason we "get to the point". In writing, a point abbreviates, structures, and finalizes what is said. Physicians puncture, and athletes collect points on playing fields, courses, and on tables. It's no wonder that researchers are "surrounded" by points and work with them every day: Points bring order to chaos, structure the unexplained, and name the nameless. A point is often the beginning, an entry to worlds, findings, or problems. Points are for everyone, though. German mathematician Oskar Perron wrote, "A point is exactly what the intelligent yet innocent, uncorrupted reader imagines it to be." We want to follow up on this quotation: The latest edition of Portal Wissen offers exciting starting points, analyzes points of view, and gets right to the point. We follow a physicist to the sun - the center point of our solar system - to ponder the origin of solar eruptions. We talked to a marketing professor about turning contentious points into successful deals during negotiation. Business information experts present leverage points that prepare both humans and machines for factories in the age of Industry 4.0. Enthusiastic entrepreneurs show us how their research became the starting point of a successful business idea - and also make the world a bit better. Geoscientists explain why the weather phenomenon El Ni{\~n}o causes - wet and dry - flashpoints. Just to name a few of many points … We hope our magazine scores points with you and wish you an inspiring read! The Editorial},

  abstract  = {Seien wir mal ehrlich: Auch Wissenschaft hat das Ziel, groß rauszukommen, zumindest im Namen der Erkenntnis. Dabei gilt doch: Wenn etwas ins Stammbuch erfolgreicher Forschung geh{\"o}rt, dann ist es wohl die Vorstellung vom Kleinen. Schließlich ist es schon immer ihr Selbstverst{\"a}ndnis gewesen, das zu ergr{\"u}nden, was sich nicht auf den ersten Blick erschließt. Schon Seneca war der Ansicht: „Wenn etwas kleiner ist als das Große, so ist es darum noch lange nicht unbedeutend." Kleinste Einheiten des Lebens wie Bakterien oder Viren bewirken Gewaltiges. Und immer wieder m{\"u}ssen (scheinbar) große Dinge erst ver- oder zerkleinert werden, um ihre Natur zu erkennen. Eines der gr{\"o}ßten Geheimnisse unserer Welt - das Atom als kleinste, wenn auch (nicht mehr) unteilbare Einheit der chemischen Elemente - hat sich erst beim Blick auf Winzigkeiten offenbart. Dabei war klein mitnichten immer nur das Gegenst{\"u}ck zu groß. Zumindest sprachlich, denn das Wort geht auf das westgermanische klaini zur{\"u}ck, das so viel wie „fein" und „zierlich" bedeutet, und ist dar{\"u}ber hinaus auch mit dem englischen clean, also „sauber", verwandt. Fein und sauber - durchaus ein erstrebenswertes Credo f{\"u}r wissenschaftliches Arbeiten. Auch ein wenig Kleinlichkeit schadet nicht. Dabei darf ein Forscher beileibe kein Kleingeist, sondern sollte bereit sein, das Unvermutete zu ahnen und seine Arbeit entsprechend darauf auszurichten. Und wenn das Ziel nicht kurzfristig zu erreichen ist, braucht es den namhaften langen Atem, sich nicht kleinreden zu lassen und klein beizugeben. Genau genommen ist Forschung eigentlich ein nicht enden wollendes Klein-klein. Jede nobelpreisw{\"u}rdige Entdeckung, jedes Großforschungsprojekt muss mit einer kleinen Idee, einem F{\"u}nklein beginnen, nur um anschließend bis ins Kleinste durchgeplant zu werden. Was folgt, die Niederungen der Ebene, ist Kleinarbeit: stundenlange Interviews auf der Suche nach dem Geheimnis des Kleinhirns, tagelange Feldstudien, die Kleinstlebewesen nachsp{\"u}ren, wochenlange Experimentreihen, die das mikroskopisch Kleine sichtbar machen sollen, monatelange Archivrecherche, die Kleinkram zutage f{\"o}rdert, oder jahrelange Lekt{\"u}re des Kleingedruckten. All das auf der Jagd nach dem großen Wurf … Darum haben wir Ihnen ein paar „Kleinigkeiten" aus der Forschung an der Universit{\"a}t Potsdam zusammengestellt, ganz nach dem Motto: Klein, aber oho! So arbeiten Ern{\"a}hrungswissenschaftler daran, einigen der kleineren Erdenbewohner - den M{\"a}usen - das Schicksal von „Laborratten" zu ersparen, indem sie Alternativen zu Tierversuchen entwickeln. Wie H{\"a}nschen klein Sprachen lernt, untersuchen Sprachwissenschaftler gleich in mehreren Projekten und mit innovativen Methoden. Nur scheinbar klitzeklein sind dagegen die Milliarden von Sternen der Magellanschen Wolken, die Potsdamer Astrophysiker im Blick haben - vom Babelsberg aus. Die Geowissenschaftler des Graduiertenkollegs „StRATEGy" wiederum waren vor Ort in Argentinien, um das (Klein-)„Kind" - das Wetterph{\"a}nomen El Ni{\~n}o - und seine Ursachen einmal genauer unter die Lupe zu nehmen. Klein anfangen, aber (die Potsdamer Kulturlandschaft) groß rausbringen soll das Research Center Sanssouci, das die Stiftung Preußische Schl{\"o}sser und G{\"a}rten und die Universit{\"a}t Potsdam gemeinsam initiiert haben. Schließlich zeigen wir, dass schon jetzt eine ganze Reihe von Projekten und Initiativen angeschoben wird, um 2019 ein Kleinod der Region neu zu entdecken: den Wanderer durch die Mark, Theodor Fontane. Wie gesagt: Kleinigkeiten. Wir w{\"u}nschen viel Spaß beim Lesen! Die Redaktion},

  abstract  = {Ein Punkt hat es in sich, auch wenn man es ihm nicht unbedingt ansieht. Immerhin gilt er in der Geometrie als Objekt ohne Ausdehnung - etwas, das da ist, aber sich nicht „breit macht". Man sollte annehmen, was so klein ist, wird leicht {\"u}bersehen. Aber Punkte sind, wenn man genauer hinschaut, nicht nur {\"u}berall zu finden, sondern auch pr{\"a}sent und spielen gewichtige Rollen. In der Physik etwa ist ein Massepunkt die h{\"o}chstm{\"o}gliche Idealisierung eines realen K{\"o}rpers: Er beschreibt die - theoretische - Vorstellung, die gesamte Masse des K{\"o}rpers w{\"a}re in einem Punkt, seinem Schwerpunkt, vereinigt. Punkte finden sich am Anfang (Ausgangspunkt), an den {\"U}berg{\"a}ngen (Dreh- und Angelpunkt) und am Ende (Schlusspunkt). Ein Punkt ist das Symbol gr{\"o}ßter Pr{\"a}zision, nicht umsonst kommt man sprichw{\"o}rtlich „auf den Punkt". Als Bestandteil unserer Schrift k{\"u}rzt er ab, gliedert und bringt Gesagtes zu Ende. Sogar Musiker und Mediziner punktieren. Und Sportler aller Arten sammeln Punkte auf Pl{\"a}tzen, Bahnen und in Tabellen. Kein Wunder, dass gerade Wissenschaftler von Punkten „umgeben" sind und t{\"a}glich mit ihnen arbeiten: Sie bringen Ordnung ins Chaos, strukturieren das Unerkl{\"a}rte, benennen das Namenlose. Allzu oft macht ein Punkt den Anfang, von dem aus sich Zug{\"a}nge er{\"o}ffnen, zu Welten, Erkenntnissen oder Problemen. Aber Punkte sind f{\"u}r alle da! Der deutsche Mathematiker Oskar Perron schrieb: „Ein Punkt ist genau das, was der intelligente, aber harmlose, unverbildete Leser sich darunter vorstellt." So wollen wir es halten: Das vorliegende Heft will spannende Ankn{\"u}pfungspunkte bieten, Standpunkte analysieren und punktgenau erkl{\"a}ren. So folgen wir etwa einem Physiker zur Sonne, in den Mittelpunkt unseres Sonnensystems, um zu ergr{\"u}nden, wie Sonneneruptionen entstehen. Mit einem Juristen diskutierten wir {\"u}ber Streitpunkte zwischen Recht und Religion, w{\"a}hrend Religionswissenschaftler in einem Reisetagebuch von einzigartigen Ber{\"u}hrungspunkten mit der (Wissenschafts-)Kultur im Iran berichten. Kognitionsund Literaturwissenschaftler er{\"o}ffnen gemeinsam besondere Blickpunkte - n{\"a}mlich, wie wir Comics lesen und verstehen - und Wirtschaftsinformatiker zeigen Ansatzpunkte, mit denen sie Mensch und Maschine gemeinsam fit machen f{\"u}r Fabriken im Zeitalter von Industrie 4.0. Bildungswissenschaftler wiederum erl{\"a}utern ihr Konzept daf{\"u}r, wie das kreative Potenzial von K{\"u}nstlern zum Ausgangspunkt werden kann, um Sch{\"u}lern einen individuellen Zugang zu Kunst zu erm{\"o}glichen. Psychologen offenbaren, warum die Farbe Rot uns zu Anziehungspunkten macht, w{\"a}hrend Geowissenschaftler erkl{\"a}ren, warum ein Klimaph{\"a}nomen namens El Ni{\~n}o weltweit - nasse und trockene - Brennpunkte verursacht. Und das sind nur einige Punkte von vielen … Mit all dem hoffen wir nat{\"u}rlich, auch bei Ihnen zu punkten. Wir w{\"u}nschen Ihnen eine anregende Lekt{\"u}re! Punkt. Aus. Ende. Nein, Anfang!

  abstract  = {We examined the spontaneous association between numbers and space by documenting attention deployment and the time course of associated spatial-numerical mapping with and without overt oculomotor responses. In Experiment 1, participants maintained central fixation while listening to number names. In Experiment 2, they made horizontal target-direct saccades following auditory number presentation. In both experiments, we continuously measured spontaneous ocular drift in horizontal space during and after number presentation. Experiment 2 also measured visual-probe-directed saccades following number presentation. Reliable ocular drift congruent with a horizontal mental number line emerged during and after number presentation in both experiments. Our results provide new evidence for the implicit and automatic nature of the oculomotor resonance effect associated with the horizontal spatial-numerical mapping mechanism.},

  abstract  = {The complexity of eye-movement control during reading allows measurement of many dependent variables, the most prominent ones being fixation durations and their locations in words. In current practice, either variable may serve as dependent variable or covariate for the other in linear mixed models (LMMs) featuring also psycholinguistic covariates of word recognition and sentence comprehension. Rather than analyzing fixation location and duration with separate LMMs, we propose linking the two according to their sequential dependency. Specifically, we include predicted fixation location (estimated in the first LMM from psycholinguistic covariates) and its associated residual fixation location as covariates in the second, fixation-duration LMM. This linked LMM affords a distinction between direct and indirect effects (mediated through fixation location) of psycholinguistic covariates on fixation durations. Results confirm the robustness of distributed processing in the perceptual span. They also offer a resolution of the paradox of the inverted optimal viewing position (IOVP) effect (i.e., longer fixation durations in the center than at the beginning and end of words) although the opposite (i.e., an OVP effect) is predicted from default assumptions of psycholinguistic processing efficiency: The IOVP effect in fixation durations is due to the residual fixation-location covariate, presumably driven primarily by saccadic error, and the OVP effect (at least the left part of it) is uncovered with the predicted fixation-location covariate, capturing the indirect effects of psycholinguistic covariates. We expect that linked LMMs will be useful for the analysis of other dynamically related multiple outcomes, a conundrum of most psychonomic research.},

  abstract  = {Die Projektierung und Abwicklung sowie die statische und dynamische Analyse von Gesch{\"a}ftsprozessen im Bereich des Verwaltens und Regierens auf kommunaler, L{\"a}nder- wie auch Bundesebene mit Hilfe von Informations- und Kommunikationstechniken besch{\"a}ftigen Politiker und Strategen f{\"u}r Informationstechnologie ebenso wie die {\"O}ffentlichkeit seit Langem. Der hieraus entstandene Begriff E-Government wurde in der Folge aus den unterschiedlichsten technischen, politischen und semantischen Blickrichtungen beleuchtet. Die vorliegende Arbeit konzentriert sich dabei auf zwei Schwerpunktthemen: • Das erste Schwerpunktthema behandelt den Entwurf eines hierarchischen Architekturmodells, f{\"u}r welches sieben hierarchische Schichten identifiziert werden k{\"o}nnen. Diese erscheinen notwendig, aber auch hinreichend, um den allgemeinen Fall zu beschreiben. Den Hintergrund hierf{\"u}r liefert die langj{\"a}hrige Prozess- und Verwaltungserfahrung als Leiter der EDV-Abteilung der Stadtverwaltung Landshut, eine kreisfreie Stadt mit rund 69.000 Einwohnern im Nordosten von M{\"u}nchen. Sie steht als Repr{\"a}sentant f{\"u}r viele Verwaltungsvorg{\"a}nge in der Bundesrepublik Deutschland und ist dennoch als Analyseobjekt in der Gesamtkomplexit{\"a}t und Prozessquantit{\"a}t {\"u}berschaubar. Somit k{\"o}nnen aus der Analyse s{\"a}mtlicher Kernabl{\"a}ufe statische und dynamische Strukturen extrahiert und abstrakt modelliert werden. Die Schwerpunkte liegen in der Darstellung der vorhandenen Bedienabl{\"a}ufe in einer Kommune. Die Transformation der Bedienanforderung in einem hierarchischen System, die Darstellung der Kontroll- und der Operationszust{\"a}nde in allen Schichten wie auch die Strategie der Fehlererkennung und Fehlerbehebung schaffen eine transparente Basis f{\"u}r umfassende Restrukturierungen und Optimierungen. F{\"u}r die Modellierung wurde FMC-eCS eingesetzt, eine am Hasso-Plattner-Institut f{\"u}r Softwaresystemtechnik GmbH (HPI) im Fachgebiet Kommunikationssysteme entwickelte Methodik zur Modellierung zustandsdiskreter Systeme unter Ber{\"u}cksichtigung m{\"o}glicher Inkonsistenzen (Betreuer: Prof. Dr.-Ing. Werner Zorn [ZW07a, ZW07b]). • Das zweite Schwerpunktthema widmet sich der quantitativen Modellierung und Optimierung von E-Government-Bediensystemen, welche am Beispiel des B{\"u}rgerb{\"u}ros der Stadt Landshut im Zeitraum 2008 bis 2015 durchgef{\"u}hrt wurden. Dies erfolgt auf Basis einer kontinuierlichen Betriebsdatenerfassung mit aufwendiger Vorverarbeitung zur Extrahierung mathematisch beschreibbarer Wahrscheinlichkeitsverteilungen. Der hieraus entwickelte Dienstplan wurde hinsichtlich der erzielbaren Optimierungen im dauerhaften Echteinsatz verifiziert.
