description: Σκοπός της παρούσας μελέτης είναι να διερευνήσει τις άμεσες ξένες επενδύσεις στην Ελλάδα, εστιάζοντας στην είσοδο των Κινέζων επενδυτών στην οικονομία της Ελλάδας με το πρόγραμμα Golden Visa. Αναπτύσσεται η σπουδαιότητα των ξένων επενδύσεων για την εθνική οικονομία, παρουσιάζονται τα πλεονεκτήματα των άμεσων ξένων επενδύσεων, αναλύεται το θεσμικό πλαίσιο που επικρατεί και επίσης αναλύεται η ωριμότητα της αγοράς ως παράγοντας ενίσχυσης των ξένων επενδύσεων. Επιπλέον εξετάζεται ο ρόλος της πολιτικής αξιοπιστίας ως ενθαρρυντικός παράγοντας της ανάπτυξης του εμπορίου. Στα πλαίσια της εργασίας διεξήχθη ποσοτική και ποιοτική έρευνα ώστε να αναδειχθούν οι αντιλήψεις όσων εμπλέκονται με το συγκεκριμένο πρόγραμμα. Συλλέχθηκαν ερωτηματολόγια από 230 Κινέζους επενδυτές στην Ελλάδα και ελήφθησαν συνεντεύξεις από τέσσερις Κινέζους επιχειρηματίες που δραστηριοποιούνται στην Ελλάδα. Τα ευρήματα της έρευνας κατέληξαν ότι υπάρχει στατιστικά σημαντική διαφορά στις αντιλήψεις μεταξύ των ανδρών και γυναικών Κινέζων επενδυτών. Επίσης, ότι ο βαθμός ικανοποίησης των Κινέζων επενδυτών από το πρόγραμμα συσχετίζεται θετικά με την αυξανόμενη απελευθέρωση του εμπορίου στην Ελλάδα, την ωριμότητα της αγοράς και την ισχύουσα οικονομική κατάσταση. Παράγοντες ανάσχεσης της ικανοποίησης είναι τα εμπόδια που θέτει το θεσμικό πλαίσιο σχετικά με την ανάπτυξη των ξένων επενδύσεων καθώς και η πολιτική ασυνέχεια.

description: This study examined several possible factors determining the profitability of small scale crop farmers in Trinidad and Tobago in the Caribbean. Industrial/urban influence on profit efficiency was tested by the creation of a special variable (IFOUR). This variable along with farming and socio-economic variables were incorporated into a translog augmented stochastic profit frontier. The significance of coefficients was tested as well as the calculation of the elasticity of profit with respect to the wage rate. The study found a significant negative impact of wage rates on profitability. Also the age of the farmer negatively affected profitability, while the number of years farming had a positive effect. This latter variable also significantly influenced both the one-sided error and idiosyncratic error terms. However IFOUR measuring industrial/urban influence did not significantly affect the profitability. The farmers had a mean profit efficiency of 48.4%, which was low in international comparisons.

description: Single-crystal nanoparticles of silicon, several tens of nm in diameter, may be suitable as building blocks for single-nanoparticle electronic devices. Previous studies of nanoparticles produced in low-pressure plasmas have demonstrated the synthesis nanocrystals of 2-10 nm diameter but larger particles were amorphous or polycrystalline. This work reports the use of a constricted, filamentary capacitively coupled low-pressure plasma to produce single-crystal silicon nanoparticles with diameters between 20-80 nm. Particles are highly oriented with predominant cubic shape. The particle size distribution is rather monodisperse. Electron microscopy studies confirm that the nanoparticles are highly oriented diamond-cubic silicon.

Census of bounded curvature paths

description: A bounded curvature path is a continuously differentiable piece-wise $C^2$ path with bounded absolute curvature connecting two points in the tangent bundle of a surface. These paths have been widely considered in computer science and engineering since the bound on curvature models the trajectory of the motion of robots under turning circle constraints. Analyzing global properties of spaces of bounded curvature paths is not a simple matter since the length variation between length minimizers of arbitrary close endpoints or directions is in many cases discontinuous. In this note, we develop a simple technology allowing us to partition the space of spaces of bounded curvature paths into one-parameter families. These families of spaces are classified in terms of the type of connected components their elements have (homotopy classes, isotopy classes, or isolated points) as we vary a parameter defined in the reals. Consequently, we answer a question raised by Dubins (Pac J Math 11(2), 1961).

description: CoV2019 has evolved to be much more dangerous than CoV2003. Experiments suggest that structural rearrangements dramatically enhance CoV2019 activity. We identify a new first stage of infection which precedes structural rearrangements by using biomolecular evolutionary theory to identify sequence differences enhancing viral attachment rates. We find a small cluster of mutations which show that CoV-2 has a new feature that promotes much stronger viral attachment and enhances contagiousness. The extremely dangerous dynamics of human coronavirus infection is a dramatic example of evolutionary approach of self-organized networks to criticality. It may favor a very successful vaccine. The identified mutations can be used to test the present theory experimentally.

Neutrino scattering rates in the presence of hyperons from a Skyrme model in the RPA approximation
Creators: name: Mornas, L.
Publisher: name: arXiv
Year: 2004
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: The contribution of Lambda hyperons to neutrino scattering rates is calculated in the random phase approximation in a model where the interaction is described by a Skyrme potential. Finite temperature and neutrino trapping are taken into account in view of applications to the deleptonization stage of protoneutron star cooling. The hyperons can remove the problem of ferromagnetic instability common to (nearly) all Skyrme parametrizations of the nucleon-nucleon interaction. As a consequence, there is not any longer a pole at the transition in the neutrino-baryon cross section. However there still remains an enhancement in this region. In the absence of ferromagnetism the mean free path in npLambda matter is reduced compared to its value in np matter as consequence of the presence of this additional degree of freedom. At high density the results are very sensitive to the choice of the Lambda-Lambda interaction.

Understanding physical property : mineralogy relationships in the context of geologic processes in the ultramafic rock-hosted mineral deposit environment : aiding interpretation of geophysical data
Creators: name: Sterritt, Victoria Athena
Publisher: name: University of British Columbia
Year: 2011

description: Inversion of potential field geophysical data to generate physical property models is becoming increasingly common in the exploration industry. This study aimed to develop relationships between physical properties and mineralogy in ultramafic rock-hosted mineral deposits, based on an analysis of the crater facies-dominated Anuri kimberlite (Canada) and the intrusive magmatic sulfide deposit at Kabanga (Tanzania). Physical property distributions for rock types and minerals that contribute to density and magnetic susceptibility were characterized in both deposits. Magnetic susceptibility is directly related to magnetite abundance, which is an igneous phase and is produced by serpentinization of ultramafic rocks of both deposits. Magnetite in kimberlite also occurs in crustal xenoliths, which dilute the diamond content. Consequently, susceptibility in the Anuri kimberlite is inversely related to diamond grade. In the Kabanga magmatic sulfide deposit, susceptibility is unrelated to ore content, but does indicate the degree of serpentinization. Density is a function of dense minerals concentrated with ore during primary sorting and settling processes in both deposits. As such, density is directly correlated with ore in both volcaniclastic kimberlite breccia of the Anuri kimberlite and ultramafic rocks at Kabanga. However, serpentinization decreases the density of ultramafic rocks significantly, masking any density anomalies associated with sulfide minerals. Modeling demonstrates that a pervasively serpentinized rock with up to 50% sulfide minerals can have a density equal to that of a barren ultramafic rock. A combination of susceptibility and density can be used to identify high-grade rocks in both deposits. In the Anuri kimberlite, rocks with high diamond contents have susceptibilities less than 10 x 10⁻³ SI and densities of 2.42 - 2.51 g/cm³. In magmatic sulfide deposits, susceptibility and density can be used to accurately calculate ore mineral abundances. Relationships developed between physical properties and mineralogy for these deposits can not only be applied to other crater facies-dominated kimberlites and both intrusive and extrusive magmatic sulfide deposits, but also to other ultramafic rock-hosted mineral deposits with comparable geologic processes. Consequently, both magnetic and gravity surveys can be interpreted in combination to give a powerful remote tool in predicting grade.

description: Urban water scarcity is an ongoing reality in California, especially, in Southern California with its arid climate and cyclical droughts. Southern California relies on upstate water imports provided by the Metropolitan Water District of Southern California (MWD) for a significant portion of its water supply. MWD also imports water from the Colorado River, conveyed through the Colorado River Aqueduct. Key to the transportation of water from the mountains in Northern California to the south is the Sacramento-San Joaquin River Delta, vulnerable to aging levees, subsidence and saltwater intrusion. In addition, the environmental deterioration of the Sacramento-San Joaquin River Delta, habitat to several endangered species, has led to ongoing restrictions on MWD water deliveries to Southern California water agencies. This has renewed efforts to both provide for the environmental improvement of the Delta ecosystem, as well as to find a solution for water conveyance, either through a canal, or more recently, through twin tunnels. In addition, the susceptibility of the Sacramento-San Joaquin River Delta to a major Bay Area earthquake increases the threat of disruption of water imports for Southern California.

description: Fluctuations in fluid velocity and fluctuations in electric fields may both give rise to forces acting on small particles in colloidal suspensions. Such forces in part determine the thermodynamic stability of the colloid. At the classical statistical thermodynamic level, the fluid velocity and electric field contributions to the forces are comparable in magnitude. When quantum fluctuation effects are taken into account, the electric fluctuation induced van der Waals forces dominate those induced by purely fluid mechanical motions. The physical principles are applied in detail for the case of colloidal particle attraction to the walls of the suspension container and more briefly for the case of forces between colloidal particles.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.

description: Vor allem aus ertragsteuerlicher Sicht kam es in den letzten Jahren zu einschlägigen neuen Regelungen bzw. Änderungen in der Gesetzgebung und Rechtsprechung im Zusammenhang mit der Behandlung von Grundstückstransaktionen (zB 1. StabG 2012 und 1. AbgÄG 2012). Dies stellt Immobilienprojektgesellschaften immer wieder vor neue Herausforderungen in der Praxis. Die vorliegende Arbeit beinhaltet einen Überblick über die ertragsteuerrechtliche Behandlung von Immobilien im Betriebsvermögen mit besonderem Blick auf Projektgesellschaften basierend auf der aktuellen Rechtslage und Rechtsprechung. Sie erklärt zunächst die unterschiedlichen Definitionen und Begriffsbestimmungen der Gesetzgebung im Zusammenhang mit Liegenschaften und erklärt weiterführend die möglichen unterschiedlichen Rechtsformen bei der Gründung einer Projektgesellschaft sowie die beliebtesten Rechtsformen in Österreich. Ein weiterer Themenbereich dieser Arbeit stellt die Veräußerung von betrieblichen Grundstücken dar, bei welcher die Einteilung in Neu- und Alt- Grundstücke bzw. die Unterteilung, ob es sich um ein steuerverfangenes oder ein nicht steuerverfangenes Grundstück handelt, essentiell ist. Anschließend wird ein praxisorientierter Abschnitt in dieser Arbeit angeführt, bei welchem die steuerlichen Unterschiede eines asset deals zu einem share deal erläutert werden, um Immobilienprojektgesellschaften einen Überblick über die Konsequenzen dieser beiden Veräußerungsformen zu geben. Danach werden die wesentlichen Merkmale der Einkünfteermittlung einer Projektgesellschaft dargelegt sowie die Begrifflichkeiten der einzelnen Posten der Einkünfteermittlung erklärt. Abschließend wird der Sonderfall der steuerlichen Liebhaberei inklusive der Prognoseberechnung im Zuge der Vermietung von Liegenschaften diskutiert. Hierbei soll geklärt werden, wann es sich um eine sogenannte große bzw. kleine Vermietung handelt und was beim Abweichen der Prognoserechnung zu beachten ist.

Ennek megfelelően nagyon kismértékű e szervezetek piaci koncentrációja, illetve nagyon alacsony szintű a másodlagos szövetkezetek piaci részesedése is. A tanulmány célja, hogy kritikai áttekintést adjon az ún. új típusú (beszerző, értékesítő, szolgáltató stb.) szövetkezetek, mezőgazdasági termelői szervezetek magyarországi helyzetének és jelentőségének alakulásáról. A cikk emellett elemzi a szövetkezetek előnyeit, illetve a sikeres szövetkezés akadályait és feltételeit, végül javaslatokat fogalmaz meg az együttműködés erősítése érdekében. ------------------- According to a recent (2011-2012) research project: “Support for Farmers’ Cooperatives” which has been commissioned and funded by European Commission, DG Agri, agricultural co-operation is underdeveloped in most of the 27 European Union Member States, a statement that is especially true in the New Member States, like Hungary. The level of market concentration of producer owned organisations (like producer groups and producer organisations) and secondary co-operation is extremely low. The aim of this study is to give a critical overview of the changes of importance and positions of the sotermed “new type” agricultural (like purchasing, marketing, service etc.) co-operatives and other producer organisations. Advantages of co-operatives, as well as obstacles and requirements of successful co-operation are analysed also and the study concludes with recommendations for strengthening co-operation among agricultural producers.

description: Purpose: We have been investigating 2D antiscatter grids (2D ASG) to reduce scatter fluence and improve image quality in cone beam computed tomography (CBCT). In this work, two different aspects of 2D ASGs, their scatter rejection and correction capability, were investigated in CBCT experiments. To correct residual scatter transmitted through the 2D ASG, it was used as a scatter measurement device with a novel method: grid-based scatter sampling. Methods: Three focused 2D ASG prototypes with grid ratios of 8, 12, and 16 were developed for linac-mounted CBCT geometry. In the first phase, 2D ASGs were used as a scatter rejection device, and the effect of grid ratio on CT number accuracy and contrast-to-noise ratio (CNR) evaluated in CBCT images. In the second phase, the grid-based scatter sampling method was implemented. The percent change in CT numbers was measured by changing the phantom size from head to pelvis configuration.Results: When 2D ASG was used as a scatter rejection device, CT number variation due to change in phantom dimensions was reduced from 23% to 2 - 6%. A grid ratio of 16 yielded the lowest CT number variation. All three 2D ASGs yielded improvement in CNR, up to a factor of two in pelvis-sized phantoms. When 2D ASG prototypes were used for both scatter rejection and correction, CT number variations were reduced further, to 1.3 - 2.6%. Conclusions: When 2D ASG was used solely as a scatter rejection device, substantial improvement in CT number accuracy could be achieved by increasing the grid ratio. 2D ASGs could also provide significant CNR improvement even at lower grid ratios. When 2D ASG was used in conjunction with the grid-based scatter sampling method, it provided further improvement in CT number accuracy, irrespective of the grid ratio, while preserving 2D ASG's capacity to improve CNR.

Bestimmte Beschaffenheit und Aufträge sind vom Anwendungsbereich des Bundesvergabegesetz (BVergG) ausgenommen. Diese Ausnahmebestimmungen sind insbesondere in § 10 und § 175 BVergG taxativ aufgelistet und eng auszulegen. § 10 Z 8 BVergG normiert, dass das BVergG nicht für Verträge über Erwerb oder Miete von oder Rechte an Grundstücken oder vorhandenen Gebäuden oder anderem unbeweglichen Vermögen, ungeachtet deren Finanzierungsmodalitäten, ausgenommen Verträge über finanzielle Dienstleistungen jeder Form, die gleichzeitig, vor oder nach dem Kauf- oder Mietvertrag abgeschlossen werden, gilt. Hintergrund für die Ausnahmeregelung ist insbesondere, dass es sich bei Grundstücken um individuelle Objekte handelt, die nicht austauschbar sind und über die daher kein Wettbewerb organisiert werden kann. Das Ziel dieser Arbeit besteht darin, einerseits eine allgemeine Einführung des Vergaberechts (BVergG) darzustellen und andererseits die Ausnahmebestimmung für Immobilien, insbesondere Miete durch öffentliche Hand, aus vergaberechtlicher Sicht systematisch darzustellen und anhand der entsprechenden Judikatur zu beurteilen. Konkret soll zunächst dargestellt werden, welche Verträge ausgenommen sind, wie diese Verträge definiert werden und in weiterer Folge soll eine Abgrenzung zwischen einem Mietvertrag und einem Bauauftrag im Sinne des § 4 Z 3 BVergG vorgenommen werden. Entsprechend der Judikate wurden in der Praxis einige Kriterien ausgearbeitet, anhand derer sich eine Abgrenzung zwischen Mietverträgen, die von der Anwendung des Vergaberechts ausgenommen sind, und Bauaufträgen, die grundsätzlich unter den Anwendungsbereich des Vergaberechts fallen, aber Elemente des Mietvertrages enthalten, vornehmen lässt. Diese Kriterien dienen lediglich als Orientierung. Die Überprüfung bedarf einer Gesamtbetrachtung und Einzelfallentscheidung.

description: The properties and applications of auxetics have been widely explored in the past years. Through proper utilization of auxetic structures, designs with unprecedented mechanical and structural behaviors can be produced. Taking advantage of this, we present the development of novel and lowcost 3D structures inspired by a simple auxetic unit. The core part, which we call the body in this paper, is a 3D realization of 2D rotating squares. This body structure was formed by joining four similar structures through softer material at the vertices. A monolithic structure of this kind is accomplished through a custom-built multi-material 3D printer. The model works in a way that, when torque is applied along the face of the rotational squares, they tend to bend at the vertex of the softer material, and due to the connected-ness of the design, a proper opening and closing motion is achieved. To demonstrate the potential of this part as an important component for robots, two applications are presented: a soft gripper and a crawling robot. Vacuum-driven actuators move both the applications. The proposed gripper combines the benefits of two types of grippers whose fingers are placed parallel and equally spaced to each other, in a single design. This gripper is adaptable to the size of the object and can grasp objects with large and small cross-sections alike. A novel bending actuator, which is made of soft material and bends in curvature when vacuumed, provides the grasping nature of the gripper. Crawling robots, in addition to their versatile nature, provide a better interaction with humans. The designed crawling robot employs negative pressure-driven actuators to highlight linear and turning locomotion.

description: We prove that every two-player nonzero-sum stopping game in discrete time admits an ε-equilibrium in randomized strategies for every ε>0. We use a stochastic variation of Ramsey's theorem, which enables us to reduce the problem to that of studying properties of ε-equilibria in a simple class of stochastic games with finite state space.

description: Silver nanoparticles on a glass substrate are experimentally investigated by aperture scanning near-field optical microscopy (a-SNOM). To understand the experimental results, finite-element-method simulations are performed building a theoretical model of the a-SNOM geometry. We systematically vary parameters like aperture size, aluminum-coating thickness, tip cone angle, and tip-surface distance and discuss their influence on the near-field enhancement. All these investigations are performed comparatively for constant-height and constant-gap scanning modes. In the end, we establish a reliable and stable optical model for simulating a-SNOM measurements, which is capable of reproducing trends observed in experimental data.

description: The aim of the study was to carry out the environmental performance of agricultural production at the regional level, taking into account production efficiency and greenhouse gas emissions from agriculture. To measure the environmental performance of agriculture a nonparametric DEA method was used. The study covered the years 2007 and 2011. It has been shown that in Poland, on average, during that period both improved utilization of production resources and reduced negative impact of production on environment have occurred. In 2011, provinces that belonged to the group with a high environmental index were: Lubuskie, Podlaskie and Kujawsko-Pomorskie. Compared to the production resources of reference province, those ones were able to produce hypothetically the largest amount of positive effects and to burden an environment with gas emissions in the relatively lowest degree, as was indicated by the indicator values of positive and negative effects. Current direction of agriculture development utilizing technological progress is favourable for production efficiency and mitigation of environmental effects
title: Active buckling control of a beam-column with circular cross-section using piezo-elastic supports and integral LQR control

description: Buckling of slender beam-columns subject to axial compressive loads represents a critical design constraint for light-weight structures. Active buckling control provides a possibility to stabilize slender beam-columns by active lateral forces or bending moments. In this paper, the potential of active buckling control of an axially loaded beam-column with circular solid cross-section by piezo-elastic supports is investigated experimentally. In the piezo-elastic supports, lateral forces of piezoelectric stack actuators are transformed into bending moments acting in arbitrary directions at the beam-column ends. A mathematical model of the axially loaded beam-column is derived to design an integral linear quadratic regulator (LQR) that stabilizes the system. The effectiveness of the stabilization concept is investigated in an experimental test setup and compared with the uncontrolled system. With the proposed active buckling control it is possible to stabilize the beam-column in arbitrary lateral direction for axial loads up to the theoretical critical buckling load of the system.

description: This article is concerned with the analysis of the one-dimensional compressible Euler equations with a singular pressure law, the so-called hard sphere equation of state. The result is twofold. First, we establish the existence of bounded weak solutions by means of a viscous regularization and refined compensated compactness arguments. Second, we investigate the smooth setting by providing a detailed description of the impact of the singular pressure on the breakdown of the solutions. In this smooth framework, we rigorously justify the singular limit towards the free-congested Euler equations, where the compressible (free) dynamics is coupled with the incompressible one in the constrained (i.e. congested) domain.

description: When being online, young users are often confronted with insulting, hateful, or misleading messages. To handle these dark forms of participation, it is essential to equip them with resources that support their social literacy in today’s complex online environments. In the present article, we deployed a previously established scale on self-perceived participatory-moral literacy and conducted a broad online survey study with 1,489 adolescents and young adults aged 16–22 years (M = 19.74; SD = 1.65; 51% female) across eight different European countries (Austria, France, Germany, Hungary, Italy, Poland, Slovakia, and the United Kingdom). The results provided a configural identical model of participatory-moral abilities, motivation, and behavior across the considered European countries. We could confirm weak invariance, satisfactory psychometric qualities, and convergent validity of the scale across the different countries. Implications for digital literacy research are discussed.
Multichannel calculation for Ds* vector states and the Ds(2632) resonance

description: We study bound states below threshold and resonances above threshold in the D0-K+ and Ds-eta systems, using a many-coupled-channel model for non-exotic meson-meson scattering applied to states with the quantum numbers of c-sbar quark-antiquark vector mesons. We fit the ground state at 2.112 GeV, whence the lowest resonances in D0-K+ come out at 2.61, 2.72, 3.03, and 3.08 GeV. The resonance at 2.61 GeV acquires a width of about 8 MeV, while its partial P-wave cross section is up to six times larger in Ds-eta than in D0-K+, provided a mechanism accounting for Okubo-Zweig-Iizuka--forbidden decays is included. The latter finding is in agreement with the observations of the SELEX collaboration with respect to the recently reported DsJ(2632) resonance. Therefore, we conclude that the DsJ(2632) is most probably the first recurrence excitation of the Ds*(2112) meson.

description: First principles computations of Raman intensities were performed for perovskite-family compound CaAl$_{1/2}$Nb$_{1/2}$O$_3$ (CAN). This compound features 1:1 (NaCl-type) ordering of Al and Nb superimposed onto the $b^-b^-c+$ octahedral tilting. Raman tensor for CAN was computed using the package for first-principles computations ABINIT (URL \underline {http://www.abinit.org}). Computations performed for both untilted cubic ($Fm\bar{3}m$) and tilted monoclinic ($P2_1/n$) CAN structures showed that the strongest Raman lines are associated with the ordering of Al and Nb. The computed spectrum agreed qualitatively with the experimental data measured on powder (CAN is available in polycrystalline form only). The effect of cation disorder on the Raman intensities was considered using phenomenological theory of light scattering in the vicinity of a phase transition. We suggest that, for certain modes, the corresponding Raman intensities depend primarily on the average long range order while, for other modes, the intensities are determined by fluctuations of the order parameter.

description: The phase difference, period and amplitude of the ACO and RCO models employed by the stochastic analysis We varied the coupling dissociation constant KC, while fixing the remaining parameter values (Table 1) and simulated the phase difference, period, and amplitude. We used the asymACO and asymRCO. For a unique time-delay of 5 h, the ACO provided the anti-phase oscillators (A); the RCO the in-phase oscillations (D). The periods of the anti-phase ACO and in-phase RCO showed the robustness to a change in KC (B, E). The amplitude of the anti-phase ACO decreased with an increase in KC (C), while the in-phase RCO determined constant amplitude (F). The amplitude of the ACO is less robust than that of the RCO.

description: Expert interviews can provide interesting data for the use in qualitative comparative analysis (QCA) to investigate complex social phenomena. To guide the challenging task of data calibration from qualitative data sets, techniques have already been suggested for the transformation of qualitative data into fuzzy sets. The current article follows existing guidelines and extends them with a system for indicator-based data calibration of expert interviews. While the underlying data set is confidential due to its corporate setting, in this article the analysis of the data is made transparent and hence reproducible for potential follow-up studies. First, the process of data collection is described, and the final data sample is characterized. Consequently, a system for indicator-based data calibration is presented and the calibration results for the empirical sample are provided in form of the set membership of cases and truth tables. • Data collection from expert interviews is described for a configurational setting • A combined indicator-based system is used for the calibration of qualitative data
