description: We study investments in R&D and the formation of R&D clusters of firms which are competitors in the market. In a three stage game, firms first decide on the budget allocated to their R&D department, then form research clusters and finally compete in quantities. The second stage cluster formation is modeled by the unanimity game introduced in Bloch(1995). We show that for any distribution of R&D investments, an equilibrium of the second stage cluster formation exists and is generically unique up to a permutation of firms which chose the same investment. Restricting to two investment levels in the first stage, we provide a complete characterization of the equilibria of the three stage game. We show that for some range of investment costs, equilibria with no-investment co-exist with equilibria where a large fraction or even all firms invest in R&D. Furthermore, in the high-investment equilibrium firms over{invest compared to a scenario where research clusters are ex-ante fixed and also compared to the welfare optimum.

description: Questo studio esamina la realizzazione discorsiva della visita guidata come genere di interazione specifico, mettendola in relazione con la natura e le propriet� dell?oggetto commentato. In particolare, l?analisi di un corpus di visite guidate di giardini etnobotanici consentir� di evidenziare gli effetti prodotti dalle specificit� del referente vegetale sia nella modalit� di co-costruzione del discorso che nel rapporto tra i partecipanti e l?oggetto dell?esposizione (exp�t). Dopo aver analizzato i procedimenti discorsivi che permettono alla guida di estrarre l?oggetto naturale dalla sua logica ordinaria per trasformarlo in segno culturale (procedimenti di tematizzazione e referenziazione, denominazione, definizione, ecc.), lo studio esplora gli effetti prodotti sull?interazione guida-visitatori dalla valorizzazione di un oggetto che non rientra nella concezione tradizionale di ?patrimonio artistico?. La natura specifica del referente vegetale influenza la dinamica del dialogo tra i partecipanti, orienta la costruzione della relazione interpersonale e attribuisce al visitatore un ruolo di prim?ordine nell?attivazione di uno spazio di memoria e di (ri-)appropriazione di conoscenze e competenze tradizionali o inedite. .

description: As for its inorganic counterparts the future developments in organic electronics are driven by an advanced device miniaturization. Therefore, the opto-electronic behavior of up-to-date devices is progressively governed by the local structural environment. However, there is a lack of organic semiconductor materials providing access to the fundamental structure-functionality relation, either due to limitations by their inherent growth or their optical characteristics. In this work we present a systematic investigation of the optical states, so-called excitons, and their temporal evolution in the prototypical organic semiconductor rubrene by means of time and temperature dependent photoluminescence studies. This material offers the unique possibility of preparing well-defined morphologies with adjustable degree of confinement. By this approach we are able to confirm the direct influence on the temperature dependent optical processes with picosecond resolution already for a spatial localization of excitation on the μm length scale. While in bulk single crystals the exciton decay dynamics are governed by thermally activated singlet fission, excitons created in microcrystals are trapped by dark states localized on the surface and leading to a pronounced enhancement of their average lifetime. Our results highlight the impact of the local environment on the excitonic states and their dynamics in organic semiconductors. With respect to the spatial dimensions of organic thin film devices, this correlation and the reported effects emerging by the confinement have to be considered upon further miniaturization and in the development of innovative device concepts, such as photovoltaic cells based on triplet-harvesting.

description: Layered transition metal dichalcogenides display a wide range of attractive physical and chemical properties and are potentially important for various device applications. Here we report the electronic transport and device properties of monolayer molybdenum disulphide (MoS2) grown by chemical vapour deposition (CVD). We show that these devices have the potential to suppress short channel effects and have high critical breakdown electric field. However, our study reveals that the electronic properties of these devices are at present, severely limited by the presence of a significant amount of band tail trapping states. Through capacitance and ac conductance measurements, we systematically quantify the density-of-states and response time of these states. Due to the large amount of trapped charges, the measured effective mobility also leads to a large underestimation of the true band mobility and the potential of the material. Continual engineering efforts on improving the sample quality are needed for its potential applications.

description: Rarely does a book about the modern ills of the welfare state excite to this degree. Cottam's accessibly written analysis of the lack of fit between Beveridge's plan for a welfare state that responded to discrete problems with specific 'neutral, depersonalised transactions' for health, income, housing and education designed to 'level opportunity and combat poverty' (p. 45) and today's chronic health conditions, persistent and elevated rates of inequality in relation to income, housing and education. Instead, Cottam argues, we need a welfare state that focuses on the relationships of kindness and care between people, and between institutions and people. Today's problems, she says, need 'collaboration, we need to be part of the change and we need systems that include all of us' (p. 46). Participation must be easy, intuitive and natural.

description: While the extant innovation literature has provided extensive evidence of the so-called "demand-pull" effect, the possible diverse impact of demand evolution on product vs process innovation activities has not been yet investigated. This paper develops a formal model predicting a larger inducing impact of past sales in fostering product rather than process innovation. This prediction is then tested through a dynamic microeconometric model, controlling for R&D persistence, sample selection, observed and unobservable individual firm effects and time and sectoral peculiarities. Results are consistent with the model and suggest that an expansionary economic policy may benefit the diffusion of new products or even the emergence of entire new sectors.

description: As technologies become more complex, the question of how transparent they should be for users and how transparency cues should be designed comes to the fore. Transparency refers to the extent to which users learn, for example, how the technology works or arrives at certain results. The increased interest in this topic also stems from legal changes such as the debate about a European AI regulation, which demands transparent AI systems and thus necessitates solutions for an optimal design of transparency cues. The paper discusses examples and risks of lacking transparency and approaches and the state of knowledge for improving the user experience by technology-based transparency cues. Finally, we present an outlook on the promising directions for design guidelines and next steps of research.

description: Im vorliegenden Forschungsprojekt wurden Webseiten der Zürcher Hochschule für Angewandte Wissenschaften (ZHAW) auf deren Web- Accessibility für Menschen mit Sehbehinderung mithilfe von Usability-Testing untersucht. Dabei wurde getestet, ob und welche digitalen Hindernisse sich bei der Nutzung der Navigations- und Webseitenelemente ergeben. Besonderer Fokus wurde auf den Aspekt der verschiedenen Zielgruppen der Webseite wie Studiums-, Weiterbildungs- und Forschungsinteressierte sowie auf Medien gelegt. Es wurden Usability-Tests mit 12 Teilnehmenden mit verschiedenen Graden von Sehbehinderung durchgeführt, die vordefinierte Aufgaben auf der Webseite lösten. Das Testing wurde sowohl mit der Desktop- als auch mit der mobilen Version durchgeführt, in Abhängigkeit der Ausgabegeräte der Teilnehmenden, die diese zum Test mitbrachten. Bei der Konzipierung und Umsetzung des Usability-Testings mussten methodische Aspekte adaptiert und praktische Aspekte einbezogen werden. Daraus konnten wertvolle Erfahrungen für Usability-Testing gewonnen werden, die für zukünftige Projekte in diesem Bereich relevant sein können. Unter anderem konnte aufgezeigt werden, dass die Kombination von ICT-Accessibility-Testing mit einem nachfolgenden Usability-Testing einen Mehrwert liefert und dies für zukünftige Projekte eine empfehlenswerte Mixed-Method-Vorgehensweise darstellt.
The life cycle of Drosophila orphan genes

description: Orphans are genes restricted to a single phylogenetic lineage and emerge at high rates. While this predicts an accumulation of genes, the gene number has remained remarkably constant through evolution. This paradox has not yet been resolved. Because orphan genes have been mainly analyzed over long evolutionary time scales, orphan loss has remained unexplored. Here we study the patterns of orphan turnover among close relatives in the Drosophila obscura group. We show that orphans are not only emerging at a high rate, but that they are also rapidly lost. Interestingly, recently emerged orphans are more likely to be lost than older ones. Furthermore, highly expressed orphans with a strong male-bias are more likely to be retained. Since both lost and retained orphans show similar evolutionary signatures of functional conservation, we propose that orphan loss is not driven by high rates of sequence evolution, but reflects lineage specific functional requirements.

description: This paper analyzes how the transferability of production capacities from an established to a new product influences the incentives of a firm to invest in R&D. A dynamic duopoly model is considered, where initially both firms offer a homogeneous product. The firms invest in production capacities and simultaneously in R&D which determines their innovation rate. The firm that innovates first extends its product line and obtains a patent for the new product that prevents the other firm from catching up. Upon the launch of the new product, the innovator then has the option to transfer part of the capacity for the established product to the production process of the new product. If capacities can be rolled over to the new product, a trade-off can be detected in that this rollover option gives the larger firm more incentive to innovate, whereas the cannibalization effect gives the smaller firm a higher innovation incentive. As a logical consequence we find that the larger firm is expected to innovate first when the capacity transfer does not involve a too high capacity loss. However, if the losses of capacity transfer are considerable, the cannibalization effect starts to dominate and the smaller firm’s incentive to innovate is larger.

description: Wide variation in visual field configuration across avian species is hypothesized to be driven primarily by foraging ecology and predator detection. While some studies of selected taxa have identified relationships between foraging ecology and binocular field characteristics in particular species, few have accounted for the relevance of shared ancestry. We conducted a large-scale, comparative analysis across 39 Anatidae species to investigate the relationship between the foraging ecology traits of diet or behaviour and binocular field parameters, while controlling for phylogeny. We used phylogenetic models to examine correlations between traits and binocular field characteristics, using unidimensional and morphometric approaches. We found that foraging behaviour influenced three parameters of binocular field size: maximum binocular field width, vertical binocular field extent and angular separation between the eye-bill projection and the direction of maximum binocular field width. Foraging behaviour and body mass each influenced two descriptors of binocular field shape. Phylogenetic relatedness had minimal influence on binocular field size and shape, apart from vertical binocular field extent. Binocular field differences are associated with specific foraging behaviours, as related to the perceptual challenges of obtaining different food items from aquatic and terrestrial environments.

description: Given a set $\mathcal{F}$ of graphs, a graph $G$ is $\mathcal{F}$-free if $G$ does not contain any member of $\mathcal{F}$ as an induced subgraph. Barrus, Kumbhat, and Hartke [M. D. Barrus, M. Kumbhat, and S. G. Hartke, Graph classes characterized both by forbidden subgraphs and degree sequences, J. Graph Theory (2008), no. 2, 131--148] called $\mathcal{F}$ a degree-sequence-forcing (DSF) set if, for each graph $G$ in the class $\mathcal{C}$ of $\mathcal{F}$-free graphs, every realization of the degree sequence of $G$ is also in $\mathcal{C}$. A DSF set is minimal if no proper subset is also DSF. In this paper, we present new properties of minimal DSF sets, including that every graph is in a minimal DSF set and that there are only finitely many DSF sets of cardinality $k$. Using these properties and a computer search, we characterize the minimal DSF triples.

description: Ethical design can mitigate potential risks of digital systems through deliberate analysis, open communication, and concretisation of potential negative effects of digital products and services for users, the environment, and society. Considering psychological needs and values helps to address ethical aspects of interactive products and services by focusing on the users’ psychological well-being. The tutorial provides knowledge about psychological needs and values as well as the ethical implications for (user) experience design. After a theoretical introduction, the participants learn first how to make the rather abstract values and psychological needs tangible. Subsequently, the participants will apply the acquired insights to conduct ethical reflection in the context of a practical experience design process. The tutorial concludes with a summary of the newly gained knowledge and a discussion about the applied methods. The results are documented and subsequently made available.

Per il primo aspetto sono indagati in particolare gli ordinamenti del terzo quarto del Settecento che interessarono entrambi gli archivi e che ne connotano tuttora la fisionomia; quindi, al di sotto di questa struttura, gli assetti che gli archivi avevano via via assunto a diverse altezze cronologiche, a partire dagli anni '20 del Quattrocento. Per quanto attiene la produzione documentaria sono analizzati in prospettiva diacronica la composizione delle strutture di cancelleria e i sistemi di organizzazione della documentazione prodotta.

Das ist wahrscheinlich der Grund, warum Design gemeinhin als die Disziplin der „kreativen Köpfe“ betrachtet wird.

description: We examine the profitability of different R&D location strategies of firms in a dynamic industry model. Firms engage in imitative and innovative activities in order to improve their products' quality, which determines their competitiveness. When choosing the set of locations in which to operate firms face a fundamental trade-off: co-locating with competitors' generates opportunities to improve product quality through imitation, but at the same time it increases the risk of losing one's competitive edge through outgoing spillovers. Being unable to fully predict competitors' moves, in making location choices firms rely on heuristics based on the expected present values associated with alternative location patterns. In a positive perspective, our model replicates key stylized facts highlighted in the pertinent empirical literature. On normative ground, we identify industry scenarios in which a firm should enter (not enter) a location even if the expected present value of doing so is negative (positive). Our key contribution is to provide a taxonomy of suitable firm location strategies depending on firm type and industry characteristics in a dynamic environment with endogenous cluster formation.

description: Wie kann man sich die ideale Persönlichkeit von UX Leaders vorstellen? Welche Persönlichkeitseigenschaften müssen UX Leaders jenseits der obligatorischen fachlichen Skills besitzen, um entscheidende Herausforderungen in ihren Unternehmen bewältigen zu können? Dieser Frage wird anhand signifikanter UX-spezifischer Problemstellungen, welche in einer Vielzahl von Unternehmen auftreten, nachgegangen. Indem wir favorisierte Bewältigungsstrategien dazu genauer untersuchen, werden wir herausfinden, wie UX Leaders oder Manager*innen gebaut sein müssen, um hier erfolgreich bestehen zu können. Es wird sich zeigen, dass UX Leaders eben mehr sein müssen als UX Professionals mit Management-Fähigkeiten. Zudem wird untersucht, welche Motivationskonstellationen UX Leaders helfen, ihre Ziele zu erreichen oder im Gegenteil einem Erfolg strukturell im Weg stehen. Schließlich wird der Bogen zur Praxis gespannt und ausgelotet, was diese Erkenntnisse für die Ausübung von UX Education und UX Hiring bedeuten.

description: An assessment is a useful tool for identifying weaknesses in human-centered design processes. An assessment is performed according to a process assessment model. Now, the latest process assessment model for HCD processes is in its final phase before the ISO standard is published (ISO/FDIS 9241-221). Using a pilot assessment based on the process reference model in the DIN ISO EN 9241-220 standard and the process assessment model, which is designed for the assessment of human-centered design processes, all 24 HCD processes have been analyzed and assessed, checking whether and how well the HCD process assessment model fulfills its purpose (proof of concept) using the previous version, ISO/DIS 9241-221. The results show that the assessment of HCD processes according to the process assessment model in ISO 9241-221 is a useful means for identifying detailed weaknesses in the HCD processes and for producing corresponding optimization opportunities for the HCD processes within organizations.

description: We investigate the scaling behavior in the statistical properties of Barkhausen noise in ferromagnetic films. We apply the statistical treatment usually employed for bulk materials in experimental Barkhausen noise time series measured with the traditional inductive technique in polycrystalline ferromagnetic films having different thickness from 100 up to 1000 nm, and investigate the scaling exponents. Based on this procedure, we can group the samples in a single universality class, characterized by exponents τ\sim 1.5, α\sim 2.0, and 1/σνz \sim \vartheta \sim 2.0. We interpret these results in terms of theoretical models and provide experimental evidence that a well-known mean-field model for the dynamics of a ferromagnetic domain wall in three-dimensional ferromagnets can be extended for films. We identify that the films present an universal three-dimensional magnetization dynamics, governed by long-range dipolar interactions, even at the smallest thicknesses, indicating that the two-dimensional magnetic behavior commonly verified for films cannot be generalized for all thickness ranges.

description: In this study we compare the evolution of labour productivity across the majority of EU member countries over the span of 1995-2016. Productivity growth combined with cross-sectoral employment shifts from manufacturing industries towards the service sectors can be observed in all countries. A shift-share analysis suggests that throughout this period most of the labour productivity growth was due to productivity gains within sectors. Labour movements between sectors, on the other hand, had small and often negative impact on labour productivity growth, especially in older EU member countries. Furthermore, the role of sectoral R&D, as one channel affecting productivity and employment is examined. We find considerable heterogeneity across sectors of the correlation between R&D expenditure and employment, but several patterns can be identified. Employment in high-tech sectors both in manufacturing and service exhibits a positive, significant correlation with R&D expenditure, while for low- and medium-tech manufacturing results are predominantly negative but sensitive to dividing the sample into subgroups of countries. There is no significant correlation between R&D expenditure and employment in low-tech service sectors.

description: Image fusion is to reduce uncertainty and minimize redundancy in the output while maximizing relevant information from two or more images of a scene into a single composite image that is more informative and is more suitable for visual perception or processing tasks like medical imaging, remote sensing, concealed weapon detection, weather forecasting, biometrics etc. Image fusion combines registered images to produce a high quality fused image with spatial and spectral information. The fused image with more information will improve the performance of image analysis algorithms used in different applications. In this paper, we proposed a fuzzy logic method to fuse images from different sensors, in order to enhance the quality and compared proposed method with two other methods i.e. image fusion using wavelet transform and weighted average discrete wavelet transform based image fusion using genetic algorithm (here onwards abbreviated as GA) along with quality evaluation parameters image quality index (IQI), mutual information measure (MIM), root mean square error (RMSE), peak signal to noise ratio (PSNR), fusion factor (FF), fusion symmetry (FS) and fusion index (FI) and entropy. The results obtained from proposed fuzzy based image fusion approach improves quality of fused image as compared to earlier reported methods, wavelet transform based image fusion and weighted average discrete wavelet transform based image fusion using genetic algorithm.

Sustainability transformation of agri-food systems: spaces of governance and coordination for territorial scaling. An empirical analysis in Italy.
Creators: name: Passaro, Alessandro
Publisher: name: Universit� degli studi di Trento
Year: 2022

description: Faced with increasing risks from climate change, food systems will need to transition away from dominant industrial paradigms and move towards a more sustainable way of producing, distributing, and consuming food. One solution or one side alone though might not have the desired systemic change or might not capture the full complexity of food systems. To go beyond two known criticisms of local food sustainable initiatives, i.e., to be rather small and to be developed outside policy frameworks and/or in stark opposition to current food systems, in this thesis I argue to look at governance spaces of transformation at local level where community members, professionals, and governments get together to share knowledge, deliberate, and collectively devise place-based strategies to address complex food systems issues. The thesis is divided into three chapters. To completely understand spaces of transformation, the first chapter provides a conceptual framework of analysis combining ideas from sustainability transitions, environmental governance and sustainable food communities? approaches. With the first chapter laying out the theoretical framework, chapter 2 and 3 will rely on the empirical analysis of data gathered through interviews and surveys. The conceptualization of territorial spaces of transformation and the analysis of whether biodistricts can be considered such spaces of transformation for food systems, will be laid out in chapter 2. Chapter 3 will consider two additional research questions, namely how territorial characteristics influence the emergence of a biodistrict, and what role the biodistricts have in territorial transformations towards agroecology. The aim of the thesis is to generate solid and harmonized evidence on the impact of biodistricts on key sustainability characteristics, such as a biodiverse environment, inclusive societal and cultural values, sustainable economic development, sound governance systems and organic, regenerative agricultural practices. The results allow to develop a blueprint for biodistricts as meso-spaces, showing how the presence of actors, the objectives, activities, and governance structure should evolve according to the maturity phases. Moreover, the application of the CAET-TAPE assessment shows that the biodistricts are performing solidly on agroecological transitions.

description: We present a detailed two-dimensional stellar dynamical analysis of a sample of 44 cosmological hydrodynamical simulations of individual central galaxies and their satellites. Kinematic maps of the stellar line-of-sight velocity, velocity dispersion, and higher-order Gauss-Hermite moments $h_3$ and $h_4$ are constructed for each central galaxy and for the most massive satellites. The amount of rotation is quantified using the $λ_{\mathrm{R}}$-parameter. The velocity, velocity dispersion, $h_3$, and $h_4$ fields of the simulated galaxies show a diversity similar to observed kinematic maps of early-type galaxies in the ATLAS$^{\rm{3D}}$ survey. This includes fast (regular), slow, and misaligned rotation, hot spheroids with embedded cold disk components as well as galaxies with counter-rotating cores or central depressions in the velocity dispersion. We link the present day kinematic properties to the individual cosmological formation histories of the galaxies. In general, major galaxy mergers have a significant influence on the rotation properties resulting in both a spin-down as well as a spin-up of the merger remnant. Lower mass galaxies with significant in-situ formation of stars, or with additional gas-rich major mergers - resulting in a spin-up - in their formation history, form elongated fast rotators with a clear anti-correlation of $h_3$ and $v/σ$. An additional formation path for fast rotators includes gas poor major mergers leading to a spin-up of the remnants. This formation path does not result in anti-correlated $h_3$ and $v/σ$. The galaxies most consistent with the rare class of non-rotating round early-type galaxies grow by gas-poor minor mergers alone. In general, more massive galaxies have less in-situ star formation since $z \sim 2$, rotate slower and have older stellar populations. (shortened)

description: Der Usability Test ist eine der wichtigsten benutzerbasierten Methoden im Human Centered Design Prozess. Der Beitrag beschreibt, wie sich möglichst viele Ergebnisse menschzentrierter Evaluationsmethoden in einem skalierten Scrum Setup verwerten lassen. Anhand der Case Study eines Großprojekts werden Erfahrungswerte vorgestellt, welche Vorgehensweisen in einem komplexen Multistakeholder-Projekt-Setup (u.A. Projektsponsor, Businessanalyse, IT-Architektur, Entwicklung, User Experience) praktikabel bzw. nicht zielführend sind. Im Besonderen wird auf Ansätze zur Übersetzung von Usability Problemen in ein Scrum taugliches Format eingegangen. Effektiv war die Weiterentwicklung vom monolithischen Usability Test Report über Epics als Sammelbecken zum konkreten Jira „Finding“. Das kompakte Format hat Potenzial eine möglichst hohe Umsetzungsquote von Testergebnissen zu sichern. So verfügen Stakeholder über gebrauchstaugliche Teilstücke für die kontinuierliche Optimierung der Nutzungsqualität des Systems.

description: The key role in the derivation of the Knizhnik-Zamolodchikov equations in the $WZW$-theory is played by the energy-momentum tensor, that is constructed from a central Casimir element of the second order in a universal enveloping algebra of a corresponding Lie algebra. In the paper a possibility of construction of analogs of Knizhnik-Zamolodchikov equations using higher order central elements is investigated. The Gelfand elements of the third order for a simple Lie algebra of series $A$ and Capelli elements of the fourth order for the a simple Lie algebra of series $B$, $D$ are considered. In the first case the construction is not possible a the second case the desired equation is derived.

description: In this paper we explore the role of social influence for the coordination of effort choice in a game with strategic complementarities. Players are repeatedly randomly partitioned in groups to play a minimum effort game and choose their effort based on their beliefs about the minimal effort among the other members of their group. Individual expectations about this minimal effort is influenced by own experience as well as by communication of beliefs within a social network. We show that increasing the importance of social influence in the expectation formation process has positive effects on the emerging (long run) effort level, thereby improving the efficiency of the outcome. Furthermore, a more centralized social network leads to higher average efficiency, but also to increased variance of outcomes. Finally, communication of actual minimum effort cannot replace the communication of beliefs as a device fostering the emergence of high long run effort.

description: We introduce fractional realizations of a graph degree sequence and a closely associated convex polytope. Simple graph realizations correspond to a subset of the vertices of this polytope. We describe properties of the polytope vertices and characterize degree sequences for which each polytope vertex corresponds to a simple graph realization. These include the degree sequences of pseudo-split graphs, and we characterize their realizations both in terms of forbidden subgraphs and graph structure.

description: Polynomial threshold gates are basic processing units of an artificial neural network. When the input vectors are binary vectors, these gates correspond to Boolean functions and can be analyzed via their polynomial representations. In practical applications, it is desirable to find a polynomial representation with the smallest number of terms possible, in order to use the least possible number of input lines to the unit under consideration. For this purpose, instead of an exact polynomial representation, usually the sign representation of a Boolean function is considered. The non-uniqueness of the sign representation allows the possibility for using a smaller number of monomials by solving a minimization problem. This minimization problem is combinatorial in nature, and so far the best known deterministic algorithm claims the use of at most $0.75\times 2^n$ of the $2^n$ total possible monomials. In this paper, the basic methods of representing a Boolean function by polynomials are examined, and an alternative approach to this problem is proposed. It is shown that it is possible to use at most $0.5\times 2^n = 2^{n-1}$ monomials based on the $\{0, 1\}$ binary inputs by introducing extra variables, and at the same time keeping the degree upper bound at $n$. An algorithm for further reduction of the number of terms that used in a polynomial representation is provided. Examples show that in certain applications, the improvement achieved by the proposed method over the existing methods is significant.

description: We present a formula for the calculation of K-edge resonant inelastic x-ray scattering on transition metal compounds, based on a local interaction between the valence shell electrons and the $1s$ core hole. Extending a previous result, we include explicit momentum dependence and a basis with multiple core-hole sites. We apply this formula to a single-layered charge, orbital and spin ordered manganite, La$_{0.5}$Sr$_{1.5}$MnO$_4$, and obtain good agreement with experimental data, in particular with regards to the large variation of the intensity with momentum. We find that the screening in La$_{0.5}$Sr$_{1.5}$MnO$_4$ is highly localized around the core-hole site and demonstrate the potential of K-edge resonant inelastic x-ray scattering as a probe of screening dynamics in materials.
