Resumen
It has been suggested that there may exist quantum correlations that go beyond entanglement. The existence of such correlations can be revealed by information theoretic quantities such as quantum discord, but not by the conventional measures of entanglement. We argue that a state displays quantumness, that can be of local and nonlocal origin. Information theoretic measures not only characterize the nonlocal quantumness, but also the local quantumness, such as the “local superposition”. This can be a reason, why such measures are nonzero, when there is no entanglement. We consider a generalized version of the Werner state to demonstrate the interplay of local quantumness, nonlocal quantumness and classical mixedness of a state.

Resumen
This thesis is concerned with determining similarity in musical audio, for the purpose of applications in music content analysis. With the aim of determining similarity, we consider the problem of representing temporal structure in music. To represent temporal structure, we propose to compute information-theoretic measures of predictability in sequences. We apply our measures to track-wise representations obtained from musical audio; thereafter we consider the obtained measures predictors of musical similarity. We demonstrate that our approach benefits music content analysis tasks based on musical similarity. For the intermediate-specificity task of cover song identification, we compare contrasting discrete-valued and continuous-valued measures of pairwise predictability between sequences. In the discrete case, we devise a method for computing the normalised compression distance (NCD) which accounts for correlation between sequences. We observe that our measure improves average performance over NCD, for sequential compression algorithms. In the continuous case, we propose to compute information-based measures as statistics of the prediction error between sequences. Evaluated using 300 Jazz standards and using the Million Song Dataset, we observe that continuous-valued approaches outperform discrete-valued approaches. Further, we demonstrate that continuous-valued measures of predictability may be combined to improve performance with respect to baseline approaches. Using a filter-and-refine approach, we demonstrate state-of-the-art performance using the Million Song Dataset. For the low-specificity tasks of similarity rating prediction and song year prediction, we propose descriptors based on computing track-wise compression rates of quantised audio features, using multiple temporal resolutions and quantisation granularities. We evaluate our descriptors using a dataset of 15 500 track excerpts of Western popular music, for which we have 7 800 web-sourced pairwise similarity ratings. Combined with bag-of-features descriptors, we obtain performance gains of 31.1% and 10.9% for similarity rating prediction and song year prediction. For both tasks, analysis of selected descriptors reveals that representing features at multiple time scales benefits prediction accuracy.

Resumen
Los modelos poligonales actualmente dominan el campo de los gráficos interactivos. Esto es debido a su simplicidad matemática que permite que los más comunes algoritmos de visualización se implementen directamente en el hardware. Sin embargo la complejidad de estos modelos (medidos por el número de polígonos) crece más rápido que la capacidad del hardware grafico para visualizarlos interactivamente. Las técnicas de simplificación de polígonos ofrecen una solución para tratar estos modelos complejos. Estos métodos simplifican la geometría poligonal reduciendo el coste de visualización del modelo sin una pérdida del contenido visual del objeto. Esta idea aun sigue vigente aunque es una idea ya antigua en gráficos por ordenador. Durante los últimos años ha surgido un gran abanico de métodos de simplificación. La mayoría ha abordado el problema de la simplificación desde el punto de vista geométrico. Es decir, elaborando métricas que permiten guiar la simplificación calculando el error cometido en cada paso utilizando una medida puramente geométrica. Recientemente se han desarrollado nuevos métodos que intentan guiar el proceso de simplificación mediante una medida de similitud visual. En otras palabras, que los modelos simplificados se vean de forma parecida cuando se visualizan.
El error geométrico es uno de los factores que influye en la similitud visual pero no es el único. Otros factores como las siluetas, las propias oclusiones y transparencias, los atributos de superficie, etc. influyen notablemente. En esta tesis se presenta un nuevo método de simplificación de mallas de polígonos. Este método realiza una simplificación guiada por el punto de vista, acometiendo una simplificación cuyo objetivo es garantizar la similitud visual. Esto permite que muchas aplicaciones cuyo objetivo sea la visualización interactiva como por ejemplo los juegos de ordenador se beneficien en buena medida. Se han propuesto diferentes métricas para conducir el método de simplificación desarrollado, todas ellas están basadas en la Teoría de la Información. El empleo de una métrica u otra permite llevar a cabo tres grandes tipos de simplificaciones. En el primer grupo se consigue una simplificación cuyo factor primordial es la similitud visual lo que conduce a la obtención de modelos simplificados cuya geometría oculta ha sido simplificada en gran medida o en su totalidad.
En el segundo grupo de métricas se aborda la simplificación con el objetivo de la similitud visual pero respetando en mayor medida la geometría oculta del modelo. Con lo que el error geométrico es menor que en grupo anterior a costa de un mayor error visual. Finalmente, el tercer grupo permite que se pueda acometer una simplificación que intenta preservar las regiones visualmente salientes de la malla mediante la aplicación del concepto de saliency de malla, definido a partir de la divergencia de Jeshen-Shannon. Estas pequeñas regiones se mantienen mejor si se hace uso de este método, de otra forma serían eliminadas ya que tienen un coste de simplificación bajo.

Resumen
Viewpoint selection has been an emerging area in computer graphics for some years, and it is now getting maturity with applications in fields such as scene navigation, volume visualization, object recognition, mesh simplification, and camera placement. But why is viewpoint selection important? For instance, automated viewpoint selection could play an important role when selecting a representative model by exploring a large 3D model database in as little time as possible. Such an application could show the model view that allows for ready recognition or understanding of the underlying 3D model. An ideal view should strive to capture the maximum information of the 3D model, such as its main characteristics, parts, functionalities, etc. The quality of this view could affect the number of models that the artist can explore in a certain period of time. In this thesis, we present an information-theoretic framework for viewpoint selection and object recognition. From a visibility channel between a set of viewpoints and the polygons of a 3D model we obtain several viewpoint quality measures from the respective decompositions of mutual information. We also review and compare in a common framework the most relevant viewpoint quality measures for polygonal models presented in the literature. From the information associated to the polygons of a model, we obtain several shading approaches to improve the object recognition and the shape perception. We also use this polygonal information to select the best views of a 3D model and to explore it. We use these polygonal information measures to enhance the visualization of a 3D terrain model generated from textured geometry coming from real data. Finally, we analyze the application of the viewpoint quality measures presented in this thesis to compute the shape similarity between 3D polygonal models. The information of the set of viewpoints is seen as a shape descriptor of the model. Then, given two models, their similarity is obtained by performing a registration process between the corresponding set of viewpoints
La selecció de punts de vista ha estat una àrea emergent en la computació gràfica des de fa alguns anys i ara està aconseguint la maduresa amb aplicacions en camps com la navegació d’una escena, la visualització de volums, el reconeixement d’objectes, la simplificació d’una malla i la col·locació de la càmera. Però per què és important la selecció del punt de vista? Per exemple, la automatització de la selecció de punts de vista podria tenir un paper important a l’hora de seleccionar un model representatiu mitjançant l’exploració d’una gran base de dades de models 3D en el menor temps possible. Aquesta aplicació podria mostrar la vista del model que permet el millor reconeixement o comprensió del model 3D. Un punt de vista ideal ha de captar la màxima informació del model 3D, com per exemple les seves principals característiques, parts, funcionalitats, etc. La qualitat d’aquest punt de vista pot afectar el nombre de models que l’artista pot explorar en un determinat període de temps. En aquesta tesi, es presenta un marc de teoria de la informació per a la selecció de punts de vista i el reconeixement d’objectes. Obtenim diverses mesures de qualitat de punt de vista a través de la descomposició de la informació mútua d’un canal de visibilitat entre un conjunt de punts de vista i els polígons d’un model 3D. També revisem i comparem en un marc comú les mesures més rellevants que s’han presentat a la literatura sobre la qualitat d’un punt de vista d’un model poligonal. A partir de la informació associada als polígons d’un model, obtenim diversos tipus de renderitzat per millorar el reconeixement d’objectes i la percepció de la forma. Utilitzem aquesta informació poligonal per seleccionar les millors vistes d’un model 3D i per la seva exploració. També usem aquestes mesures d’informació poligonal per millorar la visualització d’un model de terreny 3D amb textures generat a partir de dades reals. Finalment, s’analitza l’aplicació de les mesures de qualitat de punt de vista presentades en aquesta tesi per calcular la similitud entre dos models poligonals. La informació del conjunt de punts de vista és vista com un descriptor del model. Llavors, donats dos models poligonals, la seva similitud s’obté mitjançant la realització d’un procés de registre entre els conjunts de punts de vista corresponents

Resumen
Image matching is an area of significant use in the medical field, as there is a need to match images captured with different modalities, to overcome the limitation that can occur when dealing with individual modalities. However, performing matching of multimodal images may not be a trivial task. Multimodality entails changes in brightness and contrast that might be an obstacle when performing a match using similarity measures. This study investigated the convergence performance of information-theoretic similarity measures. The similarity measures analysed in this study are mutual information (MI), the cross-cumulative residual entropy (CCRE), and the sum of conditional variances (SCV). To analyse the convergence performance of these measures, an experiment was conducted on one data set introducing the concept of multimodality, and two single images displaying a significant variation in texture. This was to investigate the impact of multimodality and variations in texture on the convergence performance of similarity measures. The experiment investigated the ability for similarity measures to find convergence on MRI and CT medical images after a displacement has occurred. The results of the experiment showed that the convergence performance of similarity measures varies depending on the texture on images. MI is best suitable in the context of high-textured images while CCRE is more applicable in low-textured images. The measure SCV is the most stable similarity measure as it is little affected by the variation in texture. The experiment also reveals that the convergence performance of the similarity measures identified in the case of unimodality, can be preserved in the context of multimodality. This study gives better awareness of the convergence performance of similarity measures. This could improve the use of similarity measures in the medical field which could yield better diagnosis of patients’ conditions.
Matching av bilder har en stor betydelse inom det medicinska området. Detta eftersom det finns ett behov av att matcha bilder som tagits med olika modaliteter för att övervinna begränsningarna som kan uppkomma när man arbetar med en modalitet. Dock är det inte alltid trivialt att utföra matchning av multimodala bilder. Multimodalitet medför förändringar i ljusstyrka och kontrast som kan vara ett hinder vid utförande av matchning med likhetsmått.                                                           Denna rapport undersökte konvergens prestanda av informationsteoretiska likhetsmått. Likhetsmåtten som behandlades i denna studie var mutual information (MI), cross­cumulative residual entropy (CCRE), och the sum of conditional variances (SCV). För att analysera konvergens perstandat av likhesmåtten, utfördes ett experiment på en dataset som introducerar multimodalitet, och två enskilda bilder som har en betydande variation i struktur. Detta för att undersöka om konvergens av likhetsmåttena påverkas av multimodalitet och variation i struktur. Experimentet fokuserades till att undersöka möjligheten för de olika likhetsmåtten att hitta konvergens på MRI och CT medicinsiska bilder, efter att en manipulering av deras positioner har skett.                                                           Resultaten av denna studie visade att konvergens prestanda av likhetsmåtten varierade beroende på mängd struktur i datat. MI visade sig vara bäst lämpad i samband med tydlig struktur medan CCRE var mer lämplig när strukturen var mindre. SCV visade sig vara det mest stabila likhetsmåttet eftersom det inte påverkades märkbart av struktur variation. Studien visade också att konvergens beteendet av likhetsmåtten som identifierades i samband med unimodalitet, kunde bevaras i multimodalitet.                                                           Denna studie ger ökad medvetenhet om konvergens prestanda hos likhetsmåtten. Detta kan leda till en förbättrad användning av likhetsmåtten inom det medicinska området vilket kan ge möjligheter till att ställa bättre diagnoser av patienter.

Resumen
This Thesis is devoted to the construction of global climate networks (CNs) built from time series -surface air temperature anomalies (SAT)- using nonlinear analysis. Several information theory measures have been used including mutual information (MI) and conditional mutual information (CMI). The ultimate goal of the study is to improve the present understanding of climatic variability by means of networks, focusing on the different spatial and time-scales of climate phenomena. An introduction to the main components of this interdisciplinary work are offered in the first three chapters. Climate variability and patterns are introduced Chapter 1, network theory in Chapter 2, and nonlinear time series analysis -especially information theoretic methodology- in Chapter 3. In Chapter 4, the statistical similarity of SAT anomalies in different regions of the world is assessed using MI. These climate networks are constructed from time series of monthly averaged SAT anomalies, and from their symbolic ordinal representation, which allows an analysis of these interdependencies on different time scales. This analysis allows identifying topological changes in the networks when using ordinal patterns (OPs) of different time intervals. Intra-seasonal (of a few months), inter-seasonal (covering a year) and inter-annual (several years) timescales are considered. The nature of the interdependencies is then explored in Chapter 5 by using SAT data from an ensemble of atmospheric general circulation model (AGCM) runs, all of them forced by the same historical sea surface temperature (SST). It is possible to separate atmospheric variability into a forced component, and another one intrinsic to the atmosphere. In this way, it is possible to obtain climate networks for both types of variability and characterize them. Furthermore, an analysis using OP allows to construct CNs for several time scales, and evaluate the connectivity of each different network. This selecting both time scale and variability type allows to obtain a further insight into the study of SAT anomalies. The connectivity of the constructed CNs allows to assess the influence of two main climate phenomena: ENSO and the North Atlantic Oscillation (NAO). In Chapter 6, a natural extension of the network construction methodology is implemented in order to infer the direction of the links. A directionality index (DI) is used. DI can be defined as the difference of the CMI between two time series x(t) and y(t), calculated in two ways: i) considering the information about x(t) contained in t time units in the past of y(t), and ii) considering the information about y(t) contained in t time units in the past of x(t). DI is used to quantify the direction of information flow among the series, indicating the direction of the links of the network. Two SAT datasets -one monthly-averaged and another daily-averaged- are used. The links of the obtained networks are interpreted in terms of known atmospheric tropical and extra-tropical variability phenomena. Specific and relevant geographical regions are selected, the net direction of propagation of the atmospheric patterns is analyzed, and the direction of the inferred links is tested using surrogate data. These patterns are also found to be acting on various time scales, such as synoptic atmospheric waves in the extra-tropics or longer time scale events in the tropics. The final Chapter 7 presents the main conclusions, and a discussion of future work.
El objetivo de esta tesis es la creación de redes climáticas (CN por las siglas en inglés) a partir de un conjunto global de series temporales de temperatura del aire superficial (SAT), utilizando técnicas de análisis no lineal de series temporales. Varias metodologías son aplicadas al estudio de la variabilidad climática, incluyendo la Información mutua (MI) y la información mutual condicional (CMI). El objetivo principal de esta tesis es estudiar la variabilidad climática a través del análisis de redes haciendo énfasis en los diferentes patrones espaciales y temporales del sistema climático. Una introducción a los componentes principales de este trabajo interdisciplinario se presenta en los primeros tres capítulos. La variabilidad climática y los patrones atmosféricos se introducen en el Capítulo 1, la teoría de redes en el Capítulo 2, y el análisis no lineal de series temporales, especialmente metodos en teorá de la información, en el Capítulo 3. En el Capítulo 4, la similitud estadística de las anomalías de SAT en diferentes regiones del mundo es evaluada utilizando MI. Estas redes climáticas globales son construidas a partir de series temporales de SAT promediadas a escalas de tiempo mensuales, y a partir de su representación simbólica, permitiendo un análisis de estas interdependencias en varias escalas temporales. Se identifican cambios topológicos entre las redes, como resultado de variaciones en el intervalo de construcción de losOP. Escalas intra-estacionales (unos meses), inter-estacionales (cubriendo un año) e inter-anuales (varios años), son consideradas. Se encuentra que un incremento en el espaciado de los patrones ordinales (por lo tanto, en la escala de tiempo del análisis ordinal), resulta en redes climáticas con un incremento en la conectividad en el Pacífico ecuatorial. Al contrario, el número de conexiones significativas decrece al realizar el análisis ordinal en una escala de tiempo más corta (es decir, comparando meses consecutivos). Este efecto es interpretado como una consecuencia del efecto de El Niño-Oscilación Sud (ENSO) actuando en escalas de tiempo más largas y de una mayor estocasticidad en las series temporales en escalas de tiempo más cortas. La naturaleza de las interdependencias es explorada en el Capítulo 5, utilizando datos de SAT, resultantes de un conjunto de salidas de un modelo atmosférico de circulación global (AGCM), todas forzadas por la misma temperatura de la superficie del mar (SST). Es posible separar la variabilidad atmosférica en una componente forzada y otra intrínseca a la atmósfera. De esta forma, se obtienen redes climáticas para ambos tipos de variabilidad, lo que posibilita caracterizarlas. Un análisis utilizando OP permite crear CNs para diferentes escalas temporales, y encontrar la escala de OP para la cual las diferentes redes presentan mayor conectividad. Este doble proceso de selección permitie estudiar la variabilidad de las anomalías de SAT desde un nuevo punto de vista. La conectividad de las redes climáticas así construídas permite evaluar la influencia de dos fenómenos climáticos: ENSO y la Oscilación del Atlántico Norte (NAO). Para esto, se pueden comparar las redes originales, con redes provenientes de series temporales a las que se les quitaron linealmente estos fenómenos. Un resultado clave de este análisis es que la conectividad de la red de variabilidad forzada es muy afectada por ENSO: eliminando el índice NINO3.4 (que caracteriza ENSO), se provoca una pérdida general de la conectividad en la red. El hecho de que incluso conexiones entre áreas muy alejadas del océano Pacífico ecuatorial se hayan perdido al quitar el índice, sugiere que estas regiones no están directamente conectadas sino que ambas son influenciadas por la zona dominada por ENSO, especialmente en escalas de tiempo interanuales. Por otro lado, en la red de variabilidad interna, independiente del forzado de las SST, las conexiones delMar del Labrador con el resto del mundo resultan significantemente afectadas por NAO, con un máximo en escalas intra-anuales. Aunque las conexiones no locales más fuertes resultan las forzadas por el océano, se muestra la presencia de teleconexiones asociadas con la variabilidad interna. En el Capítulo 6, una extensión natural de la metodología de construcción de redes es implementada, permitiendo inferir la dirección de las conexiones. Un índice de direccionalidad (DI), puede ser definido como la diferencia entre la CMI entre dos series temporales x(t ) e y(t ) calculada de dos formas: i) considerando la información de x(t ) contenida en τ unidades de tiempo en el pasado de y(t ) y ii) considerando la información de y(t ) contenida en τ unidades de tiempo en el pasado de x(t ). Este índice DI, se utiliza para cuantificar la dirección del flujo de información entre las series, lo que equivale a la dirección de la conexión entre los respectivos nodos de la red. Dos conjuntos de series temporales, uno promediado mensualmente y el otro promediado diariamente, son usados. Las conexiones de las redes resultantes son interpretadas en términos de fenómenos de variabilidad tropical y extratropical conocidos. Regiones específicas y relevantes son seleccionadas, la dirección neta de propagación de los patrones atmosféricos es analizada y contrastada con un test de inferencia estadística. Se encuentra que diferentes patrones de variabilidad, actúan en varias escalas de tiempo, tales como ondas sinópticas atmosféricas en los extra-trópicos o escalas de tiempo mayores en los trópicos. La dependencia de valores de DI con τ es investigada. Para la escala sinóptica (τ Ç 10 días), DI presenta una dependencia con τ, con un mínimo en los trópicos y máximos (en forma de trenes de ondas) en los extra-trópicos. Para valores mayores de τ, los links resultan ser relativamente robustos a la elección del parámetro, mostrando una conectividad alta en los trópicos y baja en los extra trópicos. El análisis demuestra la capacidad de DI de inferir la dirección neta de las interacciones climáticas, y de mejorar la compresión actual de fenómenos climáticos y de la predictabilidad climática. La red resultante está en total acuerdo con los conocimientos actuales de fenómenos climáticos, validando esta metodología para inferir, directamente de los datos, la dirección neta de las interacciones climáticas. Finalmente, el Capítulo 7, presenta las conclusiones, y una discusión de trabajo futuro.

Resumen
The textbook reveals the concept and meaning of digital technologies, the legal nature of information interaction in the implementation of control measures based on general theoretical concepts and regulatory legal acts. Special attention is paid to the types of information systems used in the control process in the financial and budgetary sphere. The necessity of creating information systems based on international experience, global indices and rules of the Organization for Economic Cooperation and Development (OECD) is justified. The article defines the specific characteristics of the state information systems used in the control (monitoring) in the financial and budgetary sphere, and also considers the subsystems that make up the state integrated information system "Electronic Budget" and other information systems in the information space of the Russian Federation. The article analyzes interdepartmental information interaction and digital methods that ensure the protection of information in the course of financial control. For graduate students, postgraduates and teachers of law and non-legal universities, as well as for practitioners.

Resumen
The book Geography of Barriers: Examples of Good Barrier-free Practice offers a collection of texts that are interested in making space, services, and information accessible. Thus, the collection is primarily about barriers, their nature, localization, and possible effects. Under barriers, most people imagine material barriers for wheelchair users in the form of steps or sidewalk curbs. Only a few would think that barriers can be represented by loosely placed rugs, unfit lighting, large glass surface, a doorbell without visual output, unwanted attention, frequent asking and offering help, lack of language knowledge, pity, etc. Thus, the book broadens awareness of what can be considered a barrier. The texts are divided into three parts – theoretical, methodic, and empirical – and their arrangement follows the logic of thematic focusing from the most general to the most concrete types of barriers. While the theoretical part places the policies of accessibility into the wider context of scientific disciplines and their development – such as disability studies, disability geography or service design, the methodic part discusses the introduction of accessibility policies in the city of Brno, describing how it tried to make its space, services, and information more accessible. Finally, the empirical part offers 18 examples of relatively good barrier-free implementations that have been recently realized in Brno. This division reflects an effort to target several groups of readers. The first part thus addresses mainly students interested in accessibility issues, the second, methodic part is intended for politicians and municipalities searching for inspiration to implement their own accessibility measures and policies. The last part stating concrete examples of good barrier-free implementations is aimed at general public, at people who like to think about a whole range of topics related to accessibility of space, services, and information.

Resumen
In this paper we describe how the language skill of listening is operationalized and measured on the Duolingo English Test (DET). This work is situated in the DET’s theoretical assessment ecosystem (Burstein et al., 2022), a set of evidence-based frameworks that reflect the iterative processes for assessment design, computational psychometrics, and test security. In this ecosystem, the Language Assessment Design Framework stipulates that the domain for tested constructs be described. To achieve this goal, the present paper is one in an ongoing series of skills construct whitepapers that describes the underpinnings for each language skill construct, in this case for listening (see also Park et al., 2022 for reading; Goodwin et al., 2022 for writing; LaFlair et al., 2023 for interactional competence; Park et al., 2023 for speaking). The paper first gives background information on the DET. We then describe the DET’s conceptualization of the second language listening construct using the multi-layered framework of Aryadoust and Luo (2023). Within this framework, we consider how subskills, cognitive processes, attributes (i.e., task and test-taker traits) contribute to the overall listening construct. We also exemplify how these different elements of listening are measured through the DET item types.

Resumen
The review is about textbook on television and radio communication for students, teachers of faculties and departments of journalism, as well as journalists-practitioners, prepared by the author’s team edited by Vasyl Lyzanchuk. Textbok absorbed some considerations and conclusions from previous theoretical developments, which found a new meaning here, deeper argumentation, supplemented by many interesting observations that correspond to the spirit of the time, the innovations that have appeared in recent years in the media space of Ukraine. The textbook has ten sections, each of which is designed to enrich the student with knowledge of television and radio communications, teach him or her all that a media professional should know and be able to apply it in practice. The titles of the sections indicate their practical orientation: «Basic methodical measures of functioning of information radio and television genres», «How we analyze, interpret, explain facts, events, phenomena», «Features of the creation of artistic programs on radio and television» and others. All sections of the textbook are meaningfully connected and constructed in such a way as to provide students with the opportunity to gradually, step by step to deepen their theoretical and practical knowledge of television and radio communications. This is undoubtedly the merit of the authors of the edition. The student will benefit from the numerous examples of television and radio materials prepared by the students themselves. Their creative work should convince that this work can serve as a stimulus for creative work for future journalists during their years of study. In addition to professional competence, as rightly emphasized in the textbook by Professor Vasyl Lyzanchuk, “It is very important to form in students, future journalists, socio-national competence, deep understanding of the essence of freedom of speech and responsibility for the content of the spoken word and image, to develop the belief that they are active participants in the Ukrainian state-building processes, and not intermediaries or repeaters of information”. It should be noted that the educational element is present throughout the textbook starting with the first chapter, historical (author Professor Ivan Krupskyi). While studying this textbook, students should realize that from the honor of journalists, their dignity, patriotism depends on the honor, authority, bright name of Ukraine, its future; that their assertion of Ukrainian national identity is the key to further prosperity of our state.

Resumen
In modern conditions, innovative augmented reality technologies are actively developing, which are widespread in many areas of human activity. Introduction of advanced developments in the process of professional training of future specialists of socionomic professions in the conditions of adaptive training, contributes to the implementation of the principles of a personalized approach and increase the overall level of competitiveness. The relevant scientific article is devoted to the theoretical and empirical analysis result of conducting a psychodiagnostic study on an innovative computer complex HC-psychotest. of the features of the implementation of augmented reality technologies in the construct of traditional psychological and pedagogical support aimed at the development of emotional intelligence of the future specialist. The interdisciplinary approach was used while carrying out the research work at the expense of the general fund of the state budget: “Adaptive system for individualization and personalization of professional training of future specialists in the conditions of blended learning”. A comprehensive study of the implementation of traditional psychological-pedagogical and innovative augmented reality technologies was conducted in the framework of scientific cooperation of STEAM-Laboratory, Laboratory of Psychophysiological Research and Laboratory of Psychology of Health in Bogdan Khmelnitsky Melitopol State Pedagogical University. The theoretical analysis considers the structural model of emotional intelligence of the future specialist of socionomic professions, which is represented by two structural components: intrapersonal construct of emotional intelligence and interpersonal construct of emotional intelligence. Each component mediates the inherent emotional intelligence of interpretive, regulatory, adaptive, stress-protective and activating functions. The algorithm of the empirical block of research is presented by two stages: ascertaining and forming research. According to the results of the statement, low indicators were found on most scales, reflecting the general level of emotional intelligence development of future specialists, actualizing the need to find and implement effective measures for the development of emotional intelligence components in modern higher education and taking into account information development and digitalization. As part of the formative stage of the research implementation, a comprehensive program “Development of emotional intelligence of future professionals” was tested, which integrated traditional psychological and pedagogical technologies and innovative augmented reality technologies. This program is designed for 24 hours, 6 thematic classes of 4 hours. According to the results of a comprehensive ascertaining and shaping research, the effectiveness of the influence of augmented reality technologies on the general index of emotional intelligence is proved. The step-by-step model of integration of augmented reality components influencing the ability to analyze, understand and regulate emotional states into a complex program of emotional intelligence development is demonstrated. According to the results of the formative study, there is a dominance of high indicators of the following components: intrapersonal (50%), interpersonal (53.3%). Thus, we can say that intrapersonal and interpersonal emotional intelligence together involve the actualization of various cognitive processes and skills, and are related to each other. Empirical data were obtained as a

Sett, Dominic, Florian Waldschmidt, Alvaro Rojas-Ferreira, Saut Sagala, Teresa Arce Mojica, Preeti Koirala, Patrick Sanady et al. Climate and disaster risk analytics tool for adaptive social protection. United Nations University - Institute for Environment and Human Security, marzo de 2022. http://dx.doi.org/10.53324/wnsg2302.

Texto completo
Resumen
Adaptive Social Protection (ASP) as discussed in this report is an approach to enhance the well-being of communities at risk. As an integrated approach, ASP builds on the interface of Disaster Risk Management (DRM), Climate Change Adaptation (CCA) and Social Protection (SP) to address interconnected risks by building resilience, thereby overcoming the shortcomings of traditionally sectoral approaches. The design of meaningful ASP measures needs to be informed by specific information on risk, risk drivers and impacts on communities at risk. In contrast, a limited understanding of risk and its drivers can potentially lead to maladaptation practices. Therefore, multidimensional risk assessments are vital for the successful implementation of ASP. Although many sectoral tools to assess risks exist, available integrated risk assessment methods across sectors are still inadequate in the context of ASP, presenting an important research and implementation gap. ASP is now gaining international momentum, making the timely development of a comprehensive risk analytics tool even more important, including in Indonesia, where nationwide implementation of ASP is currently under way. OBJECTIVE: To address this gap, this study explores the feasibility of a climate and disaster risk analytics tool for ASP (CADRAT-ASP), combining sectoral risk assessment in the context of ASP with a more comprehensive risk analytics approach. Risk analytics improve the understanding of risks by locating and quantifying the potential impacts of disasters. For example, the Economics of Climate Adaptation (ECA) framework quantifies probable current and expected future impacts of extreme events and determines the monetary cost and benefits of specific risk management and adaptation measures. Using the ECA framework, this report examines the viability and practicality of applying a quantitative risk analytics approach for non-financial and non-tangible assets that were identified as central to ASP. This quantitative approach helps to identify cost-effective interventions to support risk-informed decision making for ASP. Therefore, we used Nusa Tenggara, Indonesia, as a case study, to identify potential entry points and examples for the further development and application of such an approach. METHODS & RESULTS: The report presents an analysis of central risks and related impacts on communities in the context of ASP. In addition, central social protection dimensions (SPD) necessary for the successful implementation of ASP and respective data needs from a theoretical perspective are identified. The application of the quantitative ECA framework is tested for tropical storms in the context of ASP, providing an operational perspective on technical feasibility. Finally, recommendations on further research for the potential application of a suitable ASP risk analytics tool in Indonesia are proposed. Results show that the ECA framework and its quantitative modelling platform CLIMADA successfully quantified the impact of tropical storms on four SPDs. These SPDs (income, access to health, access to education and mobility) were selected based on the results from the Hazard, Exposure and Vulnerability Assessment (HEVA) conducted to support the development of an ASP roadmap for the Republic of Indonesia (UNU-EHS 2022, forthcoming). The SPDs were modelled using remote sensing, gridded data and available global indices. The results illustrate the value of the outcome to inform decision making and a better allocation of resources to deliver ASP to the case study area. RECOMMENDATIONS: This report highlights strong potential for the application of the ECA framework in the ASP context. The impact of extreme weather events on four social protection dimensions, ranging from access to health care and income to education and mobility, were successfully quantified. In addition, further developments of CADRAT-ASP can be envisaged to improve modelling results and uptake of this tool in ASP implementation. Recommendations are provided for four central themes: mainstreaming the CADRAT approach into ASP, data and information needs for the application of CADRAT-ASP, methodological advancements of the ECA framework to support ASP and use of CADRAT-ASP for improved resilience-building. Specific recommendations are given, including the integration of additional hazards, such as flood, drought or heatwaves, for a more comprehensive outlook on potential risks. This would provide a broader overview and allow for multi-hazard risk planning. In addition, high-resolution local data and stakeholder involvement can increase both ownership and the relevance of SPDs. Further recommendations include the development of a database and the inclusion of climate and socioeconomic scenarios in analyses.

Resumen
The objective of this research was to develop and apply a conceptual framework for evaluating the potential of trans-boundary bargaining with respect to water resource sharing. The research accomplished this objective by developing a framework for trans-boundary bargaining, identifying opportunities for application, and illustrating the potential benefits that can be gained thereby. Specifically, we have accomplished the following: - Developed a framework to measure the potential for improving economic efficiency considering issues of political feasibility and sustainability that are crucial in trans-boundary cooperation. - Used both cooperative and non-cooperative game theory to assess feasible coalitions among the parties involved and to model potential bargaining procedures. - Identified empirically alternative schemes of cooperation that both improve upon the economic efficiency of present water usage and appease all of the cooperating parties. - Estimated the potential short-run and long-run affects of water reallocation on the agricultural sector and used this information to understand potential strategies taken by the countries in bargaining processes. - Performed case studies in Israeli-Jordanian relations, the relationship of Israel to the Palestinian Authority, and cooperation on the Chesapeake Bay. - Published or have in process publication of a series of refereed journal articles. - Published a book which first develops the theoretical framework, then presents research results relating to the case studies, and finally draws implications for water cooperation issues generally. Background to the Topic The increase in water scarcity and decline in water quality that has resulted from increased agricultural, industrial, and urban demands raises questions regarding profitability of the agricultural sector under its present structure. The lack of efficient management has been underscored recently by consecutive years of drought in Israel and increased needs to clean up the Chesapeake Bay. Since agriculture in the Middle East (Chesapeake Bay) is both the main water user (polluter) and the low-value user (polluter), a reallocation of water use (pollution rights) away from agriculture is likely with further industrial and urban growth. Furthermore, the trans-boundary nature of water resources in the case of the Middle East and the Chesapeake Bay contributes to increased conflicts over the use of the resources and therefore requires a political economic approach. Major Conclusions, Solutions, Achievements and Implications Using game theory tools, we critically identify obstacles to cooperation. We identify potential gains from coordination on trans-boundary water policies and projects. We identify the conditions under which partial (versus grand) coalitions dominate in solving water quality disputes among riparian countries. We identify conditions under which linking water issues to unrelated disputes achieves gains in trans-boundary negotiations. We show that gains are likely only when unrelated issues satisfy certain characteristics. We find conditions for efficient water markets under price-determined and quantity-determined markets. We find water recycling and adoption of new technologies such as desalination can be part of the solution for alleviating water shortages locally and regionally but that timing is likely to be different than anticipated. These results have been disseminated through a wide variety of publications and oral presentations as well as through interaction with policymakers in both countries.
