Resumo:

In visual and auditory scenes, we are able to identify shared features among sensory objects and group them according to their similarity. This grouping is preattentive and fast and is thought of as an elementary form of categorization by which objects sharing similar features are clustered in some abstract perceptual space. It is unclear what neuronal mechanisms underlie this fast categorization. Here we propose a neuromechanistic model of fast feature categorization based on the framework of continuous attractor networks. The mechanism for category formation does not rely on learning and is based on biologically plausible assumptions, for example, the existence of populations of neurons tuned to feature values, feature-specific interactions, and subthreshold-evoked responses upon the presentation of single objects. When the network is presented with a sequence of stimuli characterized by some feature, the network sums the evoked responses and provides a running estimate of the distribution of features in the input stream. If the distribution of features is structured into different components or peaks (i.e., is multimodal), recurrent excitation amplifies the response of activated neurons, and categories are singled out as emerging localized patterns of elevated neuronal activity (bumps), centered at the centroid of each cluster. The emergence of bump states through sequential, subthreshold activation and the dependence on input statistics is a novel application of attractor networks. We show that the extraction and representation of multiple categories are facilitated by the rich attractor structure of the network, which can sustain multiple stable activity patterns for a robust range of connectivity parameters compatible with cortical physiology.

An unresolved question in cognitive neuroscience is how representations of object categories at different levels (basic and superordinate) develop during the course of the neural response within an area. To address this, we decoded categories of different levels from the spiking responses of populations of neurons recorded in two fMRI-defined body patches in the macaque STS. Recordings of the two patches were made in the same animals with the same stimuli. Support vector machine classifiers were trained at brief response epochs and tested at the same or different epochs, thus assessing whether category representations change during the course of the response. In agreement with hierarchical processing within the body patch network, the posterior body patch mid STS body (MSB) showed an earlier onset of categorization compared with the anterior body patch anterior STS body (ASB), irrespective of the categorization level. Decoding of the superordinate body versus nonbody categories was less dynamic in MSB than in ASB, with ASB showing a biphasic temporal pattern. Decoding of the ordinate-level category human versus monkey bodies showed similar temporal patterns in both patches. The decoding onset of superordinate categorizations involving bodies was as early as for basic-level categorization, suggesting that previously reported differences between the onset of basic and superordinate categorizations may depend on the area. The qualitative difference between areas in their dynamics of category representation may hinder the interpretation of decoding dynamics based on EEG or MEG, methods that may mix signals of different areas.

The investment model of commitment has been used to understand relationship maintenance and dissolution across a variety of populations and relationship types. The current study used data from the Project on Partner Dynamics (POPD), a cohort study of young adults involved in nonmarital sexual relationships in the Los Angeles area, to test whether and how the investment model of commitment processes predicts individuals' self-reported categorizations of their relationships over time. We examined (1) how relationship categorizations are associated with variables outlined by the investment model and (2) whether model variables predict changes in relationship categorization over time. We found that changes in relationship self-categorization were associated with simultaneous changes in investment model variables, and that the model largely predicts the likelihood of future changes in relational self-categorization. These results are the first to examine how the investment model prospectively predicts the progression or regression of relationships beyond relationship dissolution.

Linguistic meaning is a convention. This article investigates how such conventions can arise for color categories in populations of simulated "agents". The method uses concepts from evolutionary game theory: A language game where agents assign names to color patches and is played repeatedly by members of a population. The evolutionary dynamics employed make minimal assumptions about agents' perceptions and learning processes. Through various simulations it is shown that under different kinds of reasonable conditions involving outcomes of individual games, the evolutionary dynamics push populations to stationary equilibria, which can be interpreted as achieving shared population meaning systems. Optimal population agreement for meaning is characterized through a mathematical formula, and the simulations presented reveal that for a wide variety of situations, optimality is achieved.

Cette thèse porte sur la question de la sémantique causative. Elle propose une typologie sémantique pour les verbes causatifs analytiques CAUSE, MAKE, HAVE, GET et LET, fondée sur le modèle de la dynamique des forces. Le premier chapitre est une étude épistémologique de l’essence de la notion de causation et de son expression linguistique en anglais. Le second chapitre situe le cadre théorique de notre analyse, à savoir la sémantique cognitive. Le troisième chapitre est un tour d’horizon des idées les plus récurrentes dans la littérature au sujet de la sémantique des verbes causatifs analytiques. Dans le quatrième chapitre, nous proposons une étude de corpus portant sur les propriétés lexico-sémantiques des verbes CAUSE, MAKE, HAVE, GET et LET. Sur la base des donnés empiriques de notre étude de corpus, nous présentons, dans le dernier chapitre, une nouvelle typologie sémantique pour les verbes causatifs analytiques anglais
This thesis deals with the semantics of causative constructions. It develops a semantic typology for English periphrastic causative verbs CAUSE, MAKE, HAVE, GET, and LET, based on the force-dynamics model. The first chapter aims to capture the essence of the notion of causation from an epistemic as well as a linguistic viewpoints. The second chapter sets the theoretical framework, which is cognitive semantics. The third chapter offers a discussion of some of the most commonly shared hypotheses about the semantics of English periphrastic causative verbs in literature. In the fourth chapter, we propose a corpus study of the lexico-semantic features of the verbs CAUSE, MAKE, HAVE, GET and LET. The last chapter presents a newly semantic typology for English periphrastic causative verbs, drawn upon the data we collected from our corpus study

Ce travail doctoral s'intéresse aux effets des processus de catégorisations sociales à l'œuvre dans un marketing politique multiculturel. Cette recherche s'intéresse particulièrement au ciblage des électeurs binationaux Français et issus de l'un des pays du Maghreb et la manière avec laquelle il affecte les dynamiques identitaires des électeurs binationaux et leurs conceptions de la citoyenneté. Nous distinguons quatre dynamiques catégorielles : de repli identitaire, de probation, adaptative et d'ancrage. Les individus vont intégrer, selon les contextes et les discours politiques auxquels ils sont confrontés, l'une de ces quatre dynamiques. Plusieurs rapports à la citoyenneté ont été identifiés, démontrant tous un besoin incessant de citoyenneté des individus. Les pratiques de marketing politique jouent dans ce cadre un rôle important dans la fabrique de catégories, faisant ainsi l'objet de plusieurs critiques. Ce travail de recherche contribue aux théories de l'identité sociale, au marketing politique et aux études marketing sur l'ethnicité
This doctoral work focuses on the effects of social categorization processes in multicultural political marketing. This research specifically examines the targeting of French dual citizens of North African descent and how it affects the identity dynamics of these dual citizens and their perceptions of citizenship. Four categorical dynamics are distinguished: identity withdrawal, probationary, adaptive, and anchoring. Individuals will adopt one of these four dynamics depending on the contexts and political discourses they encounter. Several forms of citizenship relationships have been identified, all demonstrating an ongoing need for citizenship among individuals. Political marketing practices play a significant role in shaping categories within this framework, thus subject to various criticisms. This research contributes to social identity theories, political marketing, and marketing studies on ethnicity

Ontologies provide an organization of language, in the form of a network or graph, which is amenable to computational analysis while remaining human-readable. Although they are used in a variety of disciplines, ontologies in the biomedical field, such as Gene Ontology, are of interest for their role in organizing terminology used to describe—among other concepts—the functions, locations, and processes of genes and gene-products. Due to the consistency and level of automation that ontologies provide for such annotations, methods for finding enriched biological terminology from a set of differentially identified genes in a tissue or cell sample have been developed to aid in the elucidation of disease pathology and unknown biochemical pathways. However, despite their immense utility, biomedical ontologies have significant limitations and caveats. One major issue is that gene annotation enrichment analyses often result in many redundant, individually enriched ontological terms that are highly specific and weakly justified by statistical significance. These large sets of weakly enriched terms are difficult to interpret without manually sorting into appropriate functional or descriptive categories. Also, relationships that organize the terminology within these ontologies do not contain descriptions of semantic scoping or scaling among terms. Therefore, there exists some ambiguity, which complicates the automation of categorizing terms to improve interpretability. We emphasize that existing methods enable the danger of producing incorrect mappings to categories as a result of these ambiguities, unless simplified and incomplete versions of these ontologies are used which omit problematic relations. Such ambiguities could have a significant impact on term categorization, as we have calculated upper boundary estimates of potential false categorizations as high as 121,579 for the misinterpretation of a single scoping relation, has_part, which accounts for approximately 18% of the total possible mappings between terms in the Gene Ontology. However, the omission of problematic relationships results in a significant loss of retrievable information. In the Gene Ontology, this accounts for a 6% reduction for the omission of a single relation. However, this percentage should increase drastically when considering all relations in an ontology. To address these issues, we have developed methods which categorize individual ontology terms into broad, biologically-related concepts to improve the interpretability and statistical significance of gene-annotation enrichment studies, meanwhile addressing the lack of semantic scoping and scaling descriptions among ontological relationships so that annotation enrichment analyses can be performed across a more complete representation of the ontological graph. We show that, when compared to similar term categorization methods, our method produces categorizations that match hand-curated ones with similar or better accuracy, while not requiring the user to compile lists of individual ontology term IDs. Furthermore, our handling of problematic relations produces a more complete representation of ontological information from a scoping perspective, and we demonstrate instances where medically-relevant terms--and by extension putative gene targets--are identified in our annotation enrichment results that would be otherwise missed when using traditional methods. Additionally, we observed a marginal, yet consistent improvement of statistical power in enrichment results when our methods were used, compared to traditional enrichment analyses that utilize ontological ancestors. Finally, using scalable and reproducible data workflow pipelines, we have applied our methods to several genomic, transcriptomic, and proteomic collaborative projects.

Resumo:

A document organization is a collection of documents composed of labeled clusters that contain similar documents. In any information system, a collection of documents always changes as time goes, since users access the collection to delete, add, and update documents. Dynamic Document Organization is a document organization that adapts automatically to such variable document collections. DDO poses two challenges, because of the decentralized mode of access. First, some clusters may have many documents, while others may have very few. Second, documents belonging to new topics may be added to the information system very often. Considering these two points, we need to reorganize the collection of documents, even if it was organized previously. Both text categorization and text clustering are limited when implementing DDO (Dynamic Document Organization) individually. Text categorization requires the manual preliminary tasks of the predefinition of a classification system and the preparation of sample labeled documents. Text clustering generates only unnamed clusters alone; each cluster should be labeled, manually by scanning contained documents. Therefore, this dissertation proposes approaches to the implementation of DDO that combined text clustering, cluster identification, and text categorization.

Ce travail de recherche a pour but d'investiguer du point de vue psychosocial l'identité " raciale " de la population des Noirs en France en particulier dans leur rapport avec les Blancs afin de mettre au jour les dynamiques identitaires qui existent entre les groupes.Le cadre théorique relève de la catégorisation sociale et plus particulièrement de l'un de ses développements, à savoir le concept des partitions sociales. Cette conception postule l'existence de plusieurs types de relations intercatégorielles (les partitions) qui permettent d'appréhender la nature du positionnement identitaire des individus dans le cadre d'une relation intergroupe (en fonction de l'intérêt identitaire de chacun) en y ajoutant un aspect dynamique à travers la notion de co-construction. La méthodologie utilisée relève principalement des représentations mutuelles, c'est-à-dire des représentations intercatégorielles (la représentation que l'on a de sa catégorie d'appartenance et celle que l'on a de l'exogroupe considéré) qui nous permettent de dégager les dynamiques identitaires existant entre des groupes socio-culturellement différents. Dans cette perspective, une série de d'études a été mise en œuvre. La première a mis en évidence l'existence de stratégies identitaires différentes de la part des Noirs antillais selon qu'ils vivent en Métropole ou aux Antilles. Les Antillais de Métropole s'insèrent dans une partition communautaire alors que ceux des Antilles semblent adopter une stratégie d'évitement en se recatégorisant à un niveau supraordonné. La deuxième étude a montré qu'en fonction de leur interlocuteur (opérationnalisé par les mots inducteurs " Black ", " Blanc " et " Beur "), les Français d'origine Afro-antillaise, Européenne ou Maghrébine adoptaient des positionnements identitaires différents. Enfin, une troisième étude a permis de dégager l'existence d'une discrimination implicite vis-à-vis des Noirs en France s'appuyant sur un stéréotype structuré de la même façon qu'aux États-Unis mais ne s'exprimant pas explicitement. De façon générale, ces études semblent montrer que l'appréhension des relations interethniques par le biais des partitions (et non plus en simples termes d'endofavoritisme ou d'exodéfavoritisme) permet de mieux comprendre les relations existant entre différentes communautés dans un contexte intra-national.

Queue buildup is a problem that every fast food restaurant would like to reduce, as its effect on customer satisfaction and restaurant revenue is obviously negative. This thesis looks at how a dynamic menu management system would affect fast food restaurants, specifically how the promotion of fast products, in certain situations, would affect total revenue and queue lengths. A neural network was used to categorize products depending on their preparation time and to predict queue waiting times. A simulation approach was used to find out how the menu management system would affect the restaurant. The results are that in situations where long queues are formed, the promotion of fast products increases revenue by 7.8% and decreases queue lengths by 13.3%. In situations where little to no queues are formed, the same system still decreases queue lengths by 4.7%, but also decreases revenue by 0.2%

Cette thèse aborde la question du Changement Catégoriel dans la Perception et propose une approche Dynamique qui s'appuie sur la Théorie des Catastrophes et le modèle de la FRONCE. Dans nos travaux, nous assimilons les catégories perceptives à des attracteurs d'un système dynamique non linéaire. Si notre postulat est juste, alors, un ensemble de phénomènes non linéaires théoriquement associés doivent pouvoir être observé conjointement dans un changement catégoriel qui pourrait alors être considéré comme une transition de phase. Nous avons porté notre attention sur le phénomène d'Hystérèse, déjà abondamment exploré en perception, ainsi que sur les phénomènes de divergence et de ralentissement critique. Au travers d'une série de sept expérimentations, nous confrontons l'ensemble de ces hypothèses. Nous avons confirmé la présence de ces trois phénomènes lors d'un changement catégoriel. Les résultats montrent que l'hystérèse, la divergence et le ralentissement critique sont des phénomènes observés conjointement lors d'un changement de catégorie, mais qu'ils sont aussi quantitativement reliés, comme permettait de le prédire le modèle de la fronce issue de la théorie des catastrophes. D'une manière générale, nous avons conclu que les catégories perceptives étaient fortement similaires à des d'attracteurs et que l'étude et la modélisation des changements dans la perception devraient présenter un aspect nécessairement dynamique.

In three experiments we investigated the dynamics of impression formation when perceivers encounter unsurprising (e.g. male mechanic) versus surprising (e.g. female mechanic) social category conjunctions. In Experiment 1, participants took longer to form an impression of targets described using a surprising versus an unsurprising conjunction of categorizations. In Experiment 2, we investigated the stages during which impressions of category conjunctions are formed. While unsurprising category combinations were characterized with reference to ‘constituent’ stereotypic traits, surprising combinations were characterized initially by stereotypic traits but later by ‘emergent’ impressions. In Experiment 3, we investigated motivational states that drive the dynamics of category conjunction. We found that higher Personal Need for Structure (PNS) predicted the use of more emergent and fewer constituent attributes in the impressions formed of surprising combinations. Across all three experiments, more ‘causal attributes’ were used in descriptions of the surprising combination. We discuss the implications of these findings for developing a model of the dynamics and composition of social category conjunctions.

To understand how people experience diversity, researchers have focused on category-based perceptions of others who belong to different social groups and the subsequent impact on intergroup dynamics. Specifically, scholars have focused on the automaticity of such categorizations, including stereotyping and implicit bias. This chapter will discuss these automatic, nonconscious processes, including their antecedents and their association with and effects on individual, group, and organizational outcomes. Given the automaticity of such processes, measurement strategies and suggestions for their use in future research will also be discussed.

Chapter 4 examines poverty dynamics in three distinct ways: (i) through an examination of conjunctural aspects of poverty and the events that are described as precipitating hardship, (ii) through a discussion of chronic poverty as social re-categorization, and (iii) through an exploration of gendered aspects of poverty. Together these case studies demonstrate that the discourses of poverty discussed in Chapter 2 are contested by the penetes themselves, e.g. women were able to use their social networks to resist the discourses that devalued their labour.

Cognitive Skills You Need for the 21st Century begins with the Future of Jobs Report 2018 of the World Economic Forum that describes trending skills through the year 2022. To assist with the development of these skills, the book describes techniques that should benefit everyone. The 20 chapters occupy 6 sections on acquiring knowledge (comprehension, action, categorization, abstraction), organizing knowledge (matrices, networks, hierarchies), reasoning (visuospatial reasoning, imperfect knowledge, strategies), problem-solving (problems, design, dynamics), artificial intelligence (data sciences, explainable AI, information sciences, general AI), and education (complex systems, computational thinking, continuing education). Classical research, recent research, personal anecdotes, and a few exercises provide a broad introduction to this critical topic.

Group-based disparities in education and training, employment, health, and income persist even though there is growing attention to issues of race, gender, sexuality, and economic class by academics and the public at large. This chapter reviews the contributions made by cognitive psychology, namely social identity theory and social categorization theory, to our understanding of why differences matter. Furthermore, it seeks to provide greater attention to the social and cultural context in which meaning is ascribed and enacted to group differences through turning its focus to issues of privilege, power, and diversity ideologies, which complicate the cognitive dynamics typically explored. It also seeks to understand the experience of marginalization due to group membership through an examination of group-based discrimination through the lenses of identity development theory and subsequently intersectionality.

The underlying theme of this book is that a widespread, taxonomically diverse group of animals, important both from ecological and human resource perspectives, remains poorly understood and in delcine, while receiving scant attention from the ecological and conservation community. This volume proposes a comprehensive overview of the world's river turtles' ecology, conservation, and management. It begins with a categorization of taxa which inhabit flowing water habitats followed by information on their evolutionary and physical diversity and biogeography. Within the framework of ecology, the authors discuss the composition of river turtle communities in different types of lotic habitats and regions, population dynamics, movements, reproductive characteristics and behavior, predators, and feeding relationships. In a conservation and management section, the authors identify and evaluate the nature and intensity of factors which threaten river turtle survival--almost all of which involve direct human exploitation or indirect effects of human induced habitat alteration and degradation. They then list and evaluate the various schemes which have been proposed or employed to halt declines and restore populations, and make recommendations for future management plans for specific species and regions. In closing, they state their viewpoint concerning future research directions and priorities, and an evaluation of future prospects for survival of the world's river turtle species.

This chapter provides a summary for the volume as a whole and discusses prospects for a cognitive grammar of music going forward. The first portion of the chapter reviews the main questions explored over the course of the book and the answers provided by the theoretical framework that has been set out. The second portion of the chapter sets out three ways a cognitive grammar of music might be furthered: first, through empirical research on processes of categorization, memory function, and analogies involving dynamic processes, all of which are connected with musical understanding; second, through an exploration of the relationship between the familiar constructs of music theory (like intervals, scales, and chords) and the sonic analogs for dynamic processes fundamental to musical grammar; and, third, through a continued investigation into the ways musical materials shape humans’ cultural interactions.

Michael J. McClymond traces Johannine themes in Jonthan Edwards’ theology. He first introduces some such themes in Edwards’ writings, particularly the notion of God’s continually increasing grace into eternity. Then he explores how Edwards understood the Gospel of John as a book that emphasizes spiritual meanings. He goes on to consider “the logic of fullness” in Edwards’ theology as seen in his Johannine exegesis, a logic that highlights the work of the Holy Spirit and the inexhaustible, ever-increasing grace that comes in Christ. McClymond highlights how Edwards’ treatments of Johannine themes cross multiple theological subdisciplines and thus defy neat categorization. Instead, Edwards integrated (at least) three Johannine themes into his theology—realized eschatology, interpersonal indwelling, and dynamic union—using the original concept of “the eternal and yet ever-increasing union of blessed creatures with God.”

In Liberia’s diamond sector, the dynamics of the BOPC Group show how diamond mines remain vulnerable to takeover long after war has ended. From mining to taxing to exporting, West African governments have long struggled to control the supply of diamonds within their territories and the physical and social isolation of diamond mining areas has meant that they effectively govern themselves. This geographical buffer gives extralegal groups room to grow, develop organizational structures, and build up local networks of influence. Yet their claims to legitimacy are ultimately rooted in whether their mining activities are classified as legal or illegal, formal or informal, legitimate or illegitimate. Characterizing artisanal diamond mining as an “illicit” activity also feeds into the international community’s desire to sanitize the industry—even at the expense of miners’ livelihoods. This chapter demonstrates that these categorizations are not simply claims of law, but claims of power.

The urgent need of digital transformation is caused by the colossal increase in the volumes of bibliographical information and with the aim of openness, availability and efficiency of delivering information to consumers. Digital technologies allow to significantly improve processes of search, selection and structuring of information, categorization and indexing, selectively and momentarily deliver information to consumers, create digital libraries and much more. In the article there are examples of digital technologies used in leading foreign libraries. It considers government projects of Russian Federation on digital transformation, involvement of university libraries in the process of digital transformation of bibliographical work. On the example of a selected library of Donetsk People's Republic the instruments of bibliographical work are considered. It is concluded that bibliographical work is being done in automated regime and needs further digital transformation.

Abstract This paper reviews oil (and gas) supply forecasting models and subsequently espouses atypical modeling approaches for the optimal allocation of crude oil production. This paper becomes imperative within the context of the global energy transition and the future of the oil and gas industry in Africa in general and Nigeria, in particular. A categorization framework has been utilized to classify oil supply forecasting models based on regional focus, modelling techniques, and outcomes. The log – log functional form is adopted in this paper to forecast oil production in Nigeria and subsequently optimize its allocation. A review of literature indicates that oil (and gas) supply forecasting has a long history and in recent times, there has been the tendency to rely on models that integrate engineering with economics. The models used to project oil and gas production to meet climate goals have now inputted environmental targets. This review of oil production forecast models is carried out against the backdrop of the need to optimally allocate Nigeria's future oil production to diverse uses. This will have impact on expected oil export earnings, domestic fuels’ imports, and the potential for petroleum products’ export earnings.

Abstract Within the Queensland energy industry, unconventional gas, such as Coal Seam Gas (CSG) production holds significant importance. This study employs the Continuous Wavelet Transform (CWT) to analyze variations in CSG production, aiming to comprehend its complex production dynamics. The primary objectives of this research are to identify and categorize gas rate production variations, quantify their attributes—such as frequencies, durations, and magnitudes—and explore their integration into forecasting models. The study's results demonstrate successful identification and categorization of significant variations, specifically categorizing two types of variations impulse and step events. Through the CWT, the attributes of these events are quantified. Moreover, the obtained attributes are used to refine production forecasting via applying recreated production variations to conventionally smooth forecasting models such as type curves or history matching. The broader impact of the study lies in its ability to provide deeper insights into CSG reservoir behavior. By uncovering patterns often obscured by traditional analysis methods, the CWT approach allows for better understanding of the operational dynamics. Quantifying the production variation into meaningful metrics results in more accurate and reliable production forecasts and more informed decision-making in optimizing production strategies.

<div class="section abstract"><div class="htmlview paragraph">A state-of-the-art review of the technical meaning and application of the term ‘maneuver’, used by the U.S. Army and ground vehicle engineering communities, was performed with regard to various military activities, including modeling and simulation (M&S), to focus on the value and applicability of the term to military vehicle dynamics. As shown, U.S. military doctrine has built through history and experience a unique concept of maneuver-in-general and its application in U.S. Army unified land operations. Yet, the term ‘maneuver’ needs further technical categorization and characterization for the purpose of dynamics of military unmanned ground vehicles (UGVs) and vehicle design for maneuver. While the NHTSA and SAE standards and definitions provide solid foundations for M&S of cars and trucks to enhance the safety of those vehicles (manned and autonomous), occupants, and pedestrians on roads, the standards cannot address all needs of military vehicles in maneuver. Military UGVs are designed to operate in hyper-dynamic battlefield and tactical conditions on severe terrains where manned systems cannot operate. These operational conditions require a different approach to modeling, simulation, and real-time UGV-self-assessment of its dynamic behavior to be technically capable to fulfill autonomous missions and tasks for the sake of the safety of warfighters and the UGV itself. In the paper, a technical definition for a military vehicle maneuver is presented with the purpose of encompassing vehicle agile movements with extended safety due to controllable instability and also unsafe movements on a need basis. Sub-element definitions of a vehicle maneuver and new ideation of agile movement is proposed to narrow the scope to vehicle military tasks in austere environments. Along with formulation, a graphical interpretation is provided to illustrate advantages of the proposed approach for planning UGV motion using geometric and kinematics characteristics. The contextual application is shown in an operation study to illustrate where the terms can improve M&S.</div></div>
