description: Internet censorship is a phenomenon of societal importance and attracts investigation from multiple disciplines. Several research groups, such as Censored Planet, have deployed large scale Internet measurement platforms to collect network reachability data. However, existing studies generally rely on manually designed rules (i.e., using censorship fingerprints) to detect network-based Internet censorship from the data. While this rule-based approach yields a high true positive detection rate, it suffers from several challenges: it requires human expertise, is laborious, and cannot detect any censorship not captured by the rules. Seeking to overcome these challenges, we design and evaluate a classification model based on latent feature representation learning and an image-based classification model to detect network-based Internet censorship. To infer latent feature representations fromnetwork reachability data, we propose a sequence-to-sequence autoencoder to capture the structure and the order of data elements in the data. To estimate the probability of censorship events from the inferred latent features, we rely on a densely connected multi-layer neural network model. Our image-based classification model encodes a network reachability data record as a gray-scale image and classifies the image as censored or not using a dense convolutional neural network. We compare and evaluate both approaches using data sets from Censored Planet via a hold-out evaluation. Both classification models are capable of detecting network-based Internet censorship as we were able to identify instances of censorship not detected by the known fingerprints. Latent feature representations likely encode more nuances in the data since the latent feature learning approach discovers a greater quantity, and a more diverse set, of new censorship instances.

Formation and evolution of nuclear star clusters with in-situ star-formation: Nuclear cores and age segregation

description: Nuclear stellar cluster (NSCs) are known to exist around massive black holes (MBHs) in galactic nuclei. Two formation scenarios were suggested for their origin: (1) Build-up of NSCs from consecutive infall of stellar cluster and (2) Continuous in-situ star-formation. Though the cluster-infall scenario has been extensively studied in recent years, the in-situ formation scenario have been hardly explored. Here we use Fokker-Planck (FP) calculations to study the effects of star formation on the build-up of NSCs and its implications for their long term evolution and their resulting structure. We use the FP equation to describe the evolution of several stellar populations, and add appropriate source terms to account for the effects of newly formed stars. We show that continuous star-formation even 1-2 pc away from the MBH can lead to the build-up of an NSC with properties similar to those of the Milky-way NSC. We also find that the general structure of the old stellar population in the NSC with in-situ star-formation could be very similar to the steady-state Bahcall-Wolf cuspy structure. However, its younger stellar population do not yet achieve a steady state. In particular, formed/evolved NSCs with in-situ star-formation contain differential age-segregated stellar populations which are not yet fully mixed. Younger stellar populations formed in the outer regions of the NSC have a cuspy structure towards the NSC outskirts, while showing a core-like distribution inwards; with younger populations having larger core sizes. In principal, such a structure can give rise to an apparent core-like radial distribution of younger (up to 2-3 Gyrs) stars, as observed in the Galactic center. Such an NSC still preserves an underlying stellar cusp of older stars, that can be potentially be missed by current observations of red-giants.

description: We analyze the global ground-state (quantum) phase diagram of the one-dimensional Holstein model at half-filling as a function of the strength of the electron-phonon coupling (represented by the strength of the phonon-induced attraction, $U$) and the phonon frequency, $ω_0$. In addition to reanalyzing the various asymptotic regimes, we have carried out density-matrix renormalization group simulations to correct previous inferences concerning the anti-adiabatic (large $ω_0$) and strong coupling (large $U$) regimes. There are two distinct phases - a fully gapped commensurate charge-density-wave and a spin-gapped Luther-Emery phase with a gapless charge mode - separated by a phase boundary, with a shape that reflects different microscopic physics in the weak and strong coupling limits.

description: We present a novel reinforcement learning based algorithm for multi-robot task allocation problem in warehouse environments. We formulate it as a Markov Decision Process and solve via a novel deep multi-agent reinforcement learning method (called RTAW) with attention inspired policy architecture. Hence, our proposed policy network uses global embeddings that are independent of the number of robots/tasks. We utilize proximal policy optimization algorithm for training and use a carefully designed reward to obtain a converged policy. The converged policy ensures cooperation among different robots to minimize total travel delay (TTD) which ultimately improves the makespan for a sufficiently large task-list. In our extensive experiments, we compare the performance of our RTAW algorithm to state of the art methods such as myopic pickup distance minimization (greedy) and regret based baselines on different navigation schemes. We show an improvement of upto 14% (25-1000 seconds) in TTD on scenarios with hundreds or thousands of tasks for different challenging warehouse layouts and task generation schemes. We also demonstrate the scalability of our approach by showing performance with up to $1000$ robots in simulations.

description: In this paper, we have examined the recently proposed modified symmetric teleparallel gravity, in which gravitational Lagrangian is given by an arbitrary function of non-metricity scalar $Q$. We have considered a constant jerk parameter to express the Hubble rate. Moreover, we have used 31 points of OHD datasets and 1701 points of Pantheon+ datasets to constraint our model parameters by means of the Markov Chain Monte Carlo analysis. The mean values and the best fit obtained give a consistent Hubble rate and deceleration parameter compared to the observation values. In order to study the current accelerated expansion scenario of the Universe with the presence of the cosmological fluid as a perfect fluid, we have considered two forms of teleparallel gravity. We have studied the obtained field equations with the proposed forms of $f(Q)$ models, specifically, linear $f\left( Q\right) =αQ+β$ and non-linear $f\left( Q\right) =Q+mQ^{n}$ models. Next, we have discussed the physical behavior of cosmological parameters such as energy density, pressure, EoS parameter, and deceleration parameter for both model. To ensure the validity of our proposed cosmological models, we have checked all energy conditions. The properties of these parameters confirm that our models describe the current acceleration of the expansion of the Universe. This result is also corroborated by the energy conditions criteria. the Finally, the EoS parameter for both models indicates that the cosmological fluid behaves like a quintessence dark energy model.

description: Internal crossing of trades between multiple alpha streams results in portfolio turnover reduction. Turnover reduction can be modeled using the correlation structure of the alpha streams. As more and more alphas are added, generally turnover reduces. In this note we use a factor model approach to address the question of whether the turnover goes to zero or a finite limit as the number of alphas N goes to infinity. We argue that the limiting turnover value is determined by the number of alpha clusters F, not the number of alphas N. This limiting value behaves according to the "power law" ~ F^(-3/2). So, to achieve zero limiting turnover, the number of alpha clusters must go to infinity along with the number of alphas. We further argue on general grounds that, if the number of underlying tradable instruments is finite, then the turnover cannot go to zero, which implies that the number of alpha clusters also appears to be finite.

description: We study the zero- and the finite-temperature behavior of the integrable spin-1/2 XXZ periodic chain with an impurity by the algebraic and thermal Bethe ansatz methods. We evaluate the impurity local magnetization at zero temperature analytically and derive the impurity susceptibility exactly from it. In the graphs of the impurity specific heat versus temperature, we show how the impurity spin becomes more liberated from the bulk many-body effect as the exchange coupling between the impurity spin and other spins decreases, and also that in low temperature it couples strongly to them such as the Kondo effect. Thus, we observe not only the crossover behavior from the high- to the low-temperature regime but also another one from the $N$-site chain to the $(N-1)$-site chain with a free impurity spin. We also show that the estimate of the Wilson ratio at a given low temperature is independent of the impurity parameter if its absolute value is small enough with respect to the temperature, and the universality class is described by the XXZ anisotropy in terms of the dressed charge.

Com isso adquirirem-se uma posição melhor sobre o que significa as outras áreas da matemática, que vem ao longo da vida e que iremos precisar estudar. Mas para esse momento, nossa preocupação será sobre as dificuldades que os alunos vêm desenvolvendo ao longo tempo, e que às vezes, não são sanadas, e que irá acompanha-los por um tempo ou para a vida toda. Então trazendo apenas a aritmética, que é área da nossa matemática, e que irá tratar das operações e números possíveis entre eles. Não apenas as quatro (4) operações que são extremamente fundamentais para o desenvolvimento do indivíduo, mas também a radiciação, porcentagens e exponenciação que fazem parte de toda a aritmética. Então um conteúdo importante que todo acadêmico deverá dominar ao longo da vida, é saber das quatro (4) operações básicas, com frações que até aconselha que se inteire e acesse sempre. Portanto, a aritmética se trata de um número puro, ou seja, sem letras. Se inserirmos na aritmética as letras, ela irá virar álgebra. É importante ter essa visão, para isso, abordam-se os problemas relacionados com o ensino e aprendizagem das quatro operações básicas: adição, subtração, multiplicação e divisão.

description: In composite Higgs models the Higgs is a pseudo-Goldstone boson of a high-energy strong dynamics. We have constructed the effective chiral Lagrangian for a generic symmetric coset, restricting to CP-even bosonic operators up to four momenta which turn out to depend on seven parameters, aside from kinetic terms. Once the same sources of custodial symmetry breaking as in the Standard Model are considered, the total number of operators in the basis increases up to ten, again aside from kinetic terms. Under these assumptions, we have then particularised the discussion to three distinct frameworks: the original $SU(5)/SO(5)$ Georgi-Kaplan model, the minimal custodial-preserving $SO(5)/SO(4)$ model and the minimal $SU(3)/(SU(2)\times U(1))$ model, which intrinsically breaks custodial symmetry. The projection of the high-energy electroweak effective theory into the bosonic sector of the Standard Model is shown to match the low-energy chiral effective Lagrangian for a dynamical Higgs, and it uncovers strong relations between the operator coefficients. Finally, the relation with the bosonic basis of operators describing linear realisations of electroweak symmetry breaking is clarified.

description: We analyse and report in detail new near-infrared (1.45 - 2.45 microns) observations of the Dusty S-cluster Object (DSO/G2) during its approach to the black hole at the center of the Galaxy that were carried out with ESO VLT/SINFONI between February and September 2014. Before May 2014 we detect spatially compact Br-gamma and Pa-alpha line emission from the DSO at about 40mas east of SgrA*. The velocity of the source, measured from the red-shifted emission, is 2700+-60 km/s. No blue-shifted emission above the noise level is detected at the position of SgrA* or upstream the presumed orbit. After May we find spatially compact Br-gamma blue-shifted line emission from the DSO at about 30mas west of SgrA* at a velocity of -3320+-60 km/s and no indication for significant red-shifted emission. We do not detect any significant extension of velocity gradient across the source. We find a Br-gamma-line full width at half maximum of 50+-10 Angstroem before and 15+-10 Angstroem after the peribothron transit, i.e. no significant line broadening with respect to last year is observed. Br-gamma line maps show that the bulk of the line emission originates from a region of less than 20mas diameter. This is consistent with a very compact source on an elliptical orbit with a peribothron time passage in 2014.39+-0.14. For the moment, the flaring activity of the black hole in the near-infrared regime has not shown any statistically significant increment. Increased accretion activity of SgrA* may still be upcoming. We discuss details of a source model according to which the DSO is rather a young accreting star than a coreless gas and dust cloud.

description: [Abridged] We consider extensions of the standard model based on open strings ending on D-branes. Assuming that the fundamental string mass scale M_s is in the TeV range and that the theory is weakly coupled, we discuss possible signals of string physics at the upcoming HL-LHC run (3000 fb^{-1}) with \sqrt{s} = 14 TeV, and at potential future pp colliders, HE-LHC and VLHC, operating at \sqrt{s} = 33 and 100 TeV, respectively. In such D-brane constructions, the dominant contributions to full-fledged string amplitudes for all the common QCD parton subprocesses leading to dijets and γ+ jet are completely independent of the details of compactification, and can be evaluated in a parameter-free manner. We make use of these amplitudes evaluated near the first (n=1) and second (n=2) resonant poles to determine the discovery potential for Regge excitations of the quark, the gluon, and the color singlet living on the QCD stack. We show that for string scales as large as 7.1 TeV (6.1 TeV), lowest massive Regge excitations are open to discovery at 5σin dijet (γ+ jet) HL-LHC data. We also show that for n=1, the dijet discovery potential at HE-LHC and VLHC exceedingly improves: up to 15 TeV and 41 TeV, respectively. To compute the signal-to-noise ratio for n=2 resonances, we first carry out a complete calculation of all relevant decay widths of the second massive level string states. We demonstrate that for string scales M_s

The transition takes place either upon increasing the number density of atoms in a strong field or upon increasing the field at a high enough density. It has many characteristic features of a disorder-driven (Anderson) transition but is strongly influenced by near-field interactions between atoms and the anisotropy of the atomic medium induced by the magnetic field.

description: We show theoretically that excitons can form from spatially separated one-dimensional ground state populations of electrons and holes, and that the resulting excitons can form a quasicondensate. We describe a mean-field Bardeen-Cooper-Schrieffer theory in the low carrier density regime and then focus on the core-shell nanowire giving estimates of the size of the excitonic gap for InAs/GaSb wires and as a function of all the experimentally relevant parameters. We find that optimal conditions for pairing include small overlap of the electron and hole bands, large effective mass of the carriers, and low dielectric constant of the surrounding media. Therefore, one-dimensional systems provide an attractive platform for the experimental detection of excitonic quasicondensation in zero magnetic field.

Gleichzeitig entstanden europaweit, in deutschsprachigen Raum und in Österreich, viele Musikprojekte mit „Geflüchteten“, über sie eine genaue Dokumentation, welche die Situation möglichst ersichtlich darstellt, kritische Reflexionen über gesammelte Erfahrungen präsentiert und Perspektiven der Akteur*innen („Geflüchteten“) miteinbezieht, fehlt. Im Rahmen dieser Arbeit wird versucht, durch die Untersuchung verschiedener Aspekte des Workshops „ Join in“ an der Anton Bruckner Privatuniversität Linz, der ein regelmäßiger offener Musik-Workshop für Jugendliche und Erwachsene inklusive Menschen mit Fluchterfahrung mit dem Hauptkonzept „Elementares Musizieren“ ist, mit besonderem Fokus auf die Perspektive der Farsi-sprechenden Teilnehmenden, jugendliche Afghanen und Iraner*innen, dieses Phänomen möglichst genau durchschaubar zu machen, um im weiteren Schritt anhand der Ergebnisse herauszufinden, inwieweit - und ob überhaupt - so ein Musizierprojekt zum Empowerment und/oder zur Lösung eines sozialen Problems, etwa bei kulturellen Konflikten, beitragen kann, welches das Anliegen der angewandten Ethnomusikologie ist. Die Datenerhebung erfolgte nach Methoden der Ehnomusikologie, eine Feldforschung im Laufe der 19 Musiziereinheiten in Wintersemester 2018 und Sommersemester 2019, die aktiven und passiven teilnehmenden Beobachtungen, mehrere informelle Gespräche mit den Farsi-sprechenden Teilnehmenden, den zwei Betreuern der jugendlichen Afghanen und den zwei Leiterinnen des Workshops sowie semistrukturierte Interviews mit ihnen, umfasst. Neben den Wirkungen des Workshops, wie dem Abbau von Berührungsängsten, Kontakthemmungen und Depressionen, zeigen die analysierten Daten eher ungleiche Machtverhältnisse, die das Entstehen der Möglichkeit zum Empowerment behinderten, sowie unveränderte kulturelle Konflikte zwischen zwei Farsi-sprechenden Gruppen nach der zweisemestrigen Teilnahme am Workshop. Darüber hinaus scheint es, die Nutzung von ethnomusikologischem Wissen durch die aktive Teilnahme von Ethnomusikolog*innen neben Pädagog*innen für ein effektiveres Musizierprojekt notwendig zu sein.

We identified the potential to offer interprofessional care for patients with chronic pain combined with interprofessional education at the Academic Interprofessional Chronic Pain Outpatient Clinic of the School of Medicine and Life Sciences of The Pontifícia Universidade Católica do Paraná in south Brazil. The Interprofessional Teaching-Assistance Program began in 2020 and involved initially medicine and psychology students, being expanded in 2023 to include nursing, nutrition, physiotherapy, architecture and fine arts students. We collected experience reports of some students. In three years, 315 patients were treated, 28 (8,8%) in 2020, 87 (27,6%) in 2021, 108 (34,2%) in 2022 and 92 (29,2%) in 2023. The faculty-team managed the outpatient clinic, planned teaching-learning activities, tutored students in providing interprofessional individual care and in organizing psychoeducation groups. Students report good practical learning experiences, recognition of the importance of interprofessional teamwork, development of clinical competencies and collaboration skills. The implementation of the IPE was carried out gradually and overcame the challenges. We recognize the limitations of the program and the necessity to expand the program for more students, to implement an IPE-curriculum and systematize the measures of patients and students benefits. The experience of the first years showed that it was possible to organize and manage an interprofessional assistance service for patients with chronic pain, implement an IPE teaching-learning program for medicine, psychology, nursing, physiotherapy, architecture and fine arts students. The implementation of the IPE program in the care of patients with chronic pain appears to be advantageous and benefits both patients and students.
title: Scherzkommunikation als Spiegel politischer Verhältnisse
Creators: name: Demmelbauer, Katharina
Year: 2021

description: In der vorliegende Arbeit wird untersucht, inwiefern sich die politischen Verhältnisse in den Jahren 1930 bis 1940 auf die verschiedenen Parameter der Scherzkommunikation auswirken. Als Untersuchungsgegenstand dient dabei der Comic-Strip „Tobias Seicherl“, welcher in diesen Jahren regelmäßig erschienen ist. Zunächst erfolgt eine theoretische Auseinandersetzung mit verschiedenen Aspekten der Scherzkommunikation, anschließend werden spezifische Merkmale von Comic-Strips sowie ihr Einsatz in der Politik beleuchtet. Danach erfolgt eine Auseinandersetzung mit der politischen Situation in Österreich in den Untersuchungsjahren sowie insbesondere mit den Veränderungen im Bereich des Pressewesens. Der Theorieteil schließt mit einigen allgemeinen Bemerkungen zum Comic-Strip „Tobias Seicherl“ ab, wobei vor allem auf die Besonderheit des Einsatzes des Wiener Dialekts eingegangen wird. Im praktischen Teil werden die „Seicherl-Comics“ schließlich anhand bestimmter Parameter untersucht. Zunächst erfolgt die Auswertung empirisch gewonnener Daten zu 145 „Seicherl-Geschichten“. Da es sich bei Comic-Strips um synkretistisch-semiotische Objekte handelt, werden in der Analyse neben sprachlichen Kategorien auch Bildelemente berücksichtigt. Die gewonnenen Daten werden schließlich in Hinblick auf die politischen Veränderungen interpretiert. Abschließend erfolgt eine qualitative Analyse dreier Geschichten, die sich an der Stilanalyse von Christian Braun orientiert. Die Ergebnisse fließen ergänzend in die Auswertung ein.

description: We report the realization of tunable spin-dependent splitting in intrinsic photonic spin Hall effect. By breaking the rotational symmetry of a cylindrical vector beam, the intrinsic vortex phases that the two spin components of the vector beam carries, which is similar to the geometric Pancharatnam-Berry phase, is no longer continuous in the azimuthal direction, and leads to observation of spin accumulation at the opposite edge of the beam. Due to the inherent nature of the phase and independency of light-matter interaction, the observed photonic spin Hall effect is intrinsic. Modulating the topological charge of the vector beam, the spin-dependent splitting can be enhanced and the direction of spin accumulation is switchable. Our findings may provide a possible route for generation and manipulation of spin-polarized photons, and enables spin-based photonics applications.

description: Mit dem geplanten EU Ecolabel für Finanzprodukte möchte die EU ein auf EU-Ebene etabliertes Label zur Zertifizierung nachhaltiger Geldanlagen schaffen. Ziel der Masterarbeit war es herauszufinden, welchen Stellenwert ein solches Siegel für junge Privatanlegende hätte und ob es für sie für die nachhaltige Geldanlage relevant wäre. Zur Beantwortung der Fragestellung wurde eine quantitative Studie unter Studierenden in Österreich und Deutschland im Alter von 18 bis 29 Jahren durchgeführt, welche für diese Arbeit als junge Privatanlegende definiert wurden. Zur Definition und Messung der Akzeptanz wurde ein Einstellungsmodell gewählt. Die Ergebnisse zeigen, dass das geplante EU Ecolabel für Finanzprodukte für die Zielgruppe für die Nutzung zur nachhaltigen Geldanlage relevant wäre und entsprechend der in der Studie verzeichneten Einstellungshaltung eine Chance auf Akzeptanz bei ihnen hätte. Letztere könnte sich jedoch bei Veränderung der Meinungshaltung von Gesellschaft oder Umfeld verändern. Eine Nutzung des Siegels hätte mehrheitlich den Stellenwert der Unterstützung von Nachhaltigkeit im Allgemeinen sowie der Leistung eines persönlichen Beitrags zur Nachhaltigkeit. In einem nächsten Schritt könnte sich weiterführende Forschung mit der Resonanz der Finanzinstitutionen und Unternehmen zum geplanten EU Ecolabel für Finanzprodukte beschäftigen.
description: With the planned EU Ecolabel for financial products, the EU wants to create a label established at EU level for the certification of sustainable investments. The aim of the master’s thesis was to find out what significance such a label would have for young private investors and whether it would be relevant for them for sustainable investment. To answer the question, a quantitative study was conducted among students in Austria and Germany aged 18 to 29, who were for this thesis defined as young private investors. An attitudinal model was chosen to define and measure acceptance. The results show that the planned EU Ecolabel for financial products would be relevant for the target group to use for sustainable investment and would have a chance of acceptance among them according to the attitudes recorded in the study. However, the latter could change if the attitude of society or the environment were to change. The majority of respondents would use the label to support sustainability in general and to make a personal contribution to sustainability. In a next step, further research could deal with the response of financial institutions and companies to the planned EU Ecolabel for financial products.
Stability of cosmological solutions in extended quasidilaton massive gravity

description: We consider the stability of self-accelerating solutions to extended quasidilaton massive gravity in the presence of matter. By making a second or extended fiducial metric dynamical in this model, matter can cause it to evolve from a Lorentzian to Euclidean signature, triggering a ghost instability. We study this possibility with scalar field matter as it can model a wide range of cosmological expansion histories. For the $Λ$CDM expansion history, stability considerations substantially limit the available parameter space while for a kinetic energy dominated expansion, no choice of quasidilaton parameters is stable. More generally these results show that there is no mechanism intrinsic to the theory to forbid such pathologies from developing from stable initial conditions and that stability can only be guaranteed for particular choices for the matter configuration.

Creators: name: Eberhardt, Lisa
Year: 2021

description: Die vorliegende Diplomarbeit beschäftigte sich mit der Vorwissenschaftlichen Arbeit aus dem Blickwinkel von Schüler*innen mit anderen Erstsprachen als Deutsch. Die VWA ist seit dem Schuljahr 2014/15 als dritte Säule der SRDP verankert. Den Rahmen der Forschungsarbeit bildete dabei das Kooperationsprojekt VWA-Werkstatt. Im theoretischen Teil der Arbeit wurde zunächst auf die Bildungssprache und deren ungleichheitsproduzierende Rolle und das Konzept der durchgängigen Sprachbildung eingegangen. Der weitere Fokus lag auf der VWA und den Herausforderungen, die diese insbesondere für Schüler*innen mit anderen Erstsprachen als Deutsch und ihren Schreibprozess mit sich bringt. Im empirischen Teil der Arbeit fand mittels Auswertung qualitativer Interviews die Darstellung der Perspektive der Schüler*innen statt. Dabei wurde auf die Schwierigkeiten, mit denen sie konfrontiert sind sowie auf den individuellen Schreibprozess der Schreiber*innen eingegangen. Zudem erfolgte eine qualitative Evaluation des Kooperationsprojekts und die Sammlung der Wünsche und Forderungen, die Schüler*innen hinsichtlich der Vorbereitung auf das Schreibprojekt äußern. Es wurden auch die Gründe für verspätete Abgaben betrachtet und dazu verwendet, Lösungen zur besseren Unterstützung von Schüler*innen mit Deutsch als Zweitsprache vorzuschlagen, um einen Beitrag zum erfolgreichen Schulabschluss zum Haupttermin von Schüler*innen zu leisten und ihnen einen guten Start in die akademische Zukunft zu ermöglichen.

description: We investigate the sensitivity of tritium $β$-decay experiments for keV-scale sterile neutrinos. Relic sterile neutrinos in the keV mass range can contribute both to the cold and warm dark matter content of the universe. This work shows that a large-scale tritium beta-decay experiment, similar to the KATRIN experiment that is under construction, can reach a statistical sensitivity of the active-sterile neutrino mixing of $\sin^2θ\sim 10^{-8}$. The effect of uncertainties in the known theoretical corrections to the tritium $β$-decay spectrum were investigated, and found not to affect the sensitivity significantly. It is demonstrated that controlling uncorrelated systematic effects will be one of the main challenges in such an experiment.

description: Die Unternehmensplanung ist ein Pfeiler der Unternehmenssteuerung und dient zur Prognose der zukünftigen Geschäftsentwicklung sowie als Grundlage für Entscheidungen und Maßnahmen. Es wird auf diverse Charakteristiken der Unternehmensplanung eingegangen, wie die strategische und operative Planung. Die Planungsarten fokussieren sich auf Budget und Forecast. Zu diesen werden verschiedene bisherige Studien vorgestellt. Die Forschungsfrage untersucht, wie sich in den vergangen zwei Jahren der Planungsprozess in der Bodenseeregion verändert hat und welche Treiber es für die Veränderungen gab. Die quantitative Untersuchung mittels einer Online-Umfrage erfolgt vor dem Hintergrund einer nicht nachlassenden Unsicherheit bedingt durch die Corona-Pandemie. Ein neuer Blickwinkel auf die Unternehmensplanung ist die Analyse von Unterschieden aufgrund der gewählten Unternehmensausrichtung Massenproduktion oder Auftragsfertigung. In den Ergebnissen zeigen sich keine signifikanten Unterschiede zwischen den beiden Geschäftsmodellen. Die Hälfte der befragten Unternehmen hat die Planung angepasst und z.B. die Planungsdauer verkürzt oder Szenarien verwendet.
description: Corporate Planning is a pillar of the management of companies and serves as a prognosis of the future business development as well as a basis for decisions and measures. Various characteristics of corporate planning are discussed, such as strategic and operational planning. The types of planning focus on budget and forecast. In addition, various previous studies on these are presented. The research question examines how the planning process in the Lake Constance region has changed in the past two years and what the drivers for the changes were. The quantitative investigation via an online survey is carried out against the background of an ongoing uncertainty caused by the Corona pandemic. A new perspective on corporate planning is the analysis of differences due to the chosen corporate orientation towards mass production or contract manufacturing. The results show no significant differences between the two business models. Half of the companies surveyed have adapted their planning and, for example, shortened the planning period or used scenarios.
