401	Environmental Design Research and the Design of Urban Open Space: A Study of Current Practice in Landscape Architecture Masters, Jennifer 01 January 2012 (has links) (PDF) A large and growing body of research exists on how the design of the environment can positively or negatively affect people’s health and well-being, as well as influence their behavior. Researchers in this field, known as “environmental design research,” have long acknowledged the challenge of translating their findings into formats that are accepted and used by practitioners. This study explores how environmental design research on urban open space and the practice-oriented translations of it are used by landscape architects who have been recognized in the profession for their designs of parks, plazas, and streets in urban areas. Through interviews with practitioners, an understanding emerges of the impact of environmental design research on contemporary practice, leading to recommendations that could enhance it in the future. Key findings of the study indicate that translations of the research, specifically in the form of design guidelines, while intended to inform practice, are not widely used by designers. Rather, to understand how design impacts human behavior, practitioners rely primarily on what they refer to as intuition, largely informed by their own direct observations of people in public space. The quality of their personal observations, therefore, is critical to their depth of understanding of human behavior and the environment. The study concludes with recommendations that could improve the skills of design students and practitioners to conduct, interpret, and apply their own direct observations in their designs, using methods and findings from the field of environmental design research to inform and enrich this process. urban open space environmental design research environment-behavior research human behavior human health and well-being design guidelines landscape architecture practice design education and pedagogy research methods post-occupancy evaluation Curriculum and Instruction Environmental Design Landscape Architecture
402	Modeling, Training, and Teaming Approaches for Cyber-Physical-Human Systems Sooyung Byeon (18431625) 26 April 2024 (has links) <p dir="ltr">Cyber-physical-human systems (CPHSs) integrate human cognitive capabilities into the decision and control processes of complex dynamical systems. While artificial intelligence (AI) has shown promise in controlling such systems, it often encounters challenges such as conflict with human behavior and brittleness. Moreover, even successful AI implementations may lead to negative impacts on humans, such as the degradation of manual skills and diminished situation awareness, thereby weakening humans' ability to effectively monitor and intervene in off-nominal conditions as the final decision-makers of the systems. To address these unique challenges within CPHSs, this dissertation proposes three key approaches. First, human behavior modeling approaches are proposed to enhance understanding and prediction of human behavior from the perspective of AI. Accurate modeling enables better calibration of AI's expectations regarding human teammates' intentions and skill-levels. Second, a novel shared control approach is developed to expedite human training for complex dynamic control tasks. An assistant agent supports human novices in emulating human experts by leveraging human behavior models to gauge the human's skill-levels and provide tailored assistance to help improve one's skill. Lastly, human-autonomy teaming (HAT) design is addressed from a resource allocation perspective. A systematic computational simulation approach is proposed to optimize function and attention allocation to manage trade-offs in performance, situation awareness, workload, and other considerations. The proposed frameworks are demonstrated via examples in drone applications. Numerical and experimental results, utilizing simulation platforms and human subjects, validate the efficacy of the proposed approaches. This dissertation presents significant progress in the design and implementation of CPHSs in that it offers insights and methodologies to enhance collaborative interactions between humans and autonomous systems in complex environments.</p> Cyber-physical-social system Cyber-physical-human system human-AI cooperation Human Behavior Modeling Human Training human-autonomy collaboration
403	Enhanching the Human-Team Awareness of a Robot Wåhlin, Peter January 2012 (has links) The use of autonomous robots in our society is increasing every day and a robot is no longer seen as a tool but as a team member. The robots are now working side by side with us and provide assistance during dangerous operations where humans otherwise are at risk. This development has in turn increased the need of robots with more human-awareness. Therefore, this master thesis aims at contributing to the enhancement of human-aware robotics. Specifically, we are investigating the possibilities of equipping autonomous robots with the capability of assessing and detecting activities in human teams. This capability could, for instance, be used in the robot's reasoning and planning components to create better plans that ultimately would result in improved human-robot teamwork performance. we propose to improve existing teamwork activity recognizers by adding intangible features, such as stress, motivation and focus, originating from human behavior models. Hidden markov models have earlier been proven very efficient for activity recognition and have therefore been utilized in this work as a method for classification of behaviors. In order for a robot to provide effective assistance to a human team it must not only consider spatio-temporal parameters for team members but also the psychological.To assess psychological parameters this master thesis suggests to use the body signals of team members. Body signals such as heart rate and skin conductance. Combined with the body signals we investigate the possibility of using System Dynamics models to interpret the current psychological states of the human team members, thus enhancing the human-awareness of a robot. / Användningen av autonoma robotar i vårt samhälle ökar varje dag och en robot ses inte längre som ett verktyg utan som en gruppmedlem. Robotarna arbetar nu sida vid sida med oss och ger oss stöd under farliga arbeten där människor annars är utsatta för risker. Denna utveckling har i sin tur ökat behovet av robotar med mer människo-medvetenhet. Därför är målet med detta examensarbete att bidra till en stärkt människo-medvetenhet hos robotar. Specifikt undersöker vi möjligheterna att utrusta autonoma robotar med förmågan att bedöma och upptäcka olika beteenden hos mänskliga lag. Denna förmåga skulle till exempel kunna användas i robotens resonemang och planering för att ta beslut och i sin tur förbättra samarbetet mellan människa och robot. Vi föreslår att förbättra befintliga aktivitetsidentifierare genom att tillföra förmågan att tolka immateriella beteenden hos människan, såsom stress, motivation och fokus. Att kunna urskilja lagaktiviteter inom ett mänskligt lag är grundläggande för en robot som ska vara till stöd för laget. Dolda markovmodeller har tidigare visat sig vara mycket effektiva för just aktivitetsidentifiering och har därför använts i detta arbete. För att en robot ska kunna ha möjlighet att ge ett effektivt stöd till ett mänskligtlag måste den inte bara ta hänsyn till rumsliga parametrar hos lagmedlemmarna utan även de psykologiska. För att tyda psykologiska parametrar hos människor förespråkar denna masteravhandling utnyttjandet av mänskliga kroppssignaler. Signaler så som hjärtfrekvens och hudkonduktans. Kombinerat med kroppenssignalerar påvisar vi möjligheten att använda systemdynamiksmodeller för att tolka immateriella beteenden, vilket i sin tur kan stärka människo-medvetenheten hos en robot. / <p>The thesis work was conducted in Stockholm, Kista at the department of Informatics and Aero System at Swedish Defence Research Agency.</p> robotics Artificial Intelligence AI System Dynamics Wireless Body Area Network WBAN sensors Psychology physiology human behavior Human-Robot-Interaction HRI robot Human-Team awareness human-robot RapidMiner Vensim JaHMM hidden markov models HMM eclipse rcp ARFF recognizer classification cross-validation human behavior stress detection Galvanic Skin Response Heart Rate Skin Temperature Finger Temperature Electrocardiogram ECG GSR ST Pupil Diameter PD Patient monitoring GPS Data acquisition dataset data set MODERE Yerkes-Dodson SD model SD Confusion matrix spatial MOUT Java Agent robotic agent Machine Learning activity recognition team oriented robot Evaluation Decoding Learning Forward Algorithm Backward Algorithm Baum-Welch feedback loop Situation Awareness SA Shared Mental Models SMM
404	Gènes et comportements: au-delà de l'inné et de l'acquis / Gene and behaviors: beyond nature and nurture Perbal, Laurence 11 March 2009 (has links) Le contexte historique et épistémologique de l’émergence de la génétique des comportements en tant que discipline trouve ses racines dans différentes disciplines biologiques :la génétique, la biologie de l’évolution et la biologie moléculaire. Ces dernières font partie du paradigme néodarwinien moléculaire. De cette origine, elle a hérité deux grands domaines de recherche, la génétique quantitative et la génétique moléculaire. Ils ont chacun des objectifs et des méthodologies différents. Les études concernant l’intelligence, les comportements agressifs, les comportements addictifs et l’orientation sexuelle permettent notamment d’illustrer ces différences. Elles permettent également de faire un état des lieux des recherches menées dans ce domaine parfois hautement polémique. En fait, la génétique des comportements est marquée par deux ères épistémologiques, l’ère génomique qui a débuté dans les années 1980 et l’ère post-génomique, qui comme son nom l’indique, lui succède dès le début des années 2000. Les résultats apportés par l’ensemble de ces recherches imposent une conclusion, les approches théoriques et techniques phares de l’ère génomique sont insuffisantes à rendre compte de la complexité des phénomènes développementaux liés aux comportements. L’ère post-génomique tente donc de combler les faiblesses de l’ère précédente. Ainsi, la biologie développementale revient au premier plan et ce retour est souhaité depuis longtemps par un courant philosophique majeur né dans les années 1990, la Developmental Systems Theory. L’ère post-génomique est également caractérisée par un pluralisme pragmatique, à la fois théorique et expérimental. La nécessité de multiplier les modes d’appréhension des comportements s’impose car leur complexité intrinsèque est reconnue et tend à être assumée. Les résultats plus récents apportés par les recherches sur l’intelligence, les comportements agressifs, addictifs et l’orientation sexuelle illustrent cette évolution épistémologique. L’opposition entre inné et acquis échoue à rendre compte de la complexité et du dynamisme développemental des phénotypes comportementaux./ The historical and epistemological context of the birth of behavioral genetics as a discipline has its roots in different biological domains: genetics, evolutionary biology and molecular biology. They are parts of the molecular neo-Darwinian paradigm. From this multiple outset, behavioral genetics has inherited two major areas of research, quantitative genetics and molecular genetics. They each have different purposes and methodologies. The study of researches on IQ, aggressive behaviors, addictive behaviors and sexual orientation illustrate these differences. It also permits to make an overview of results provided in this field that is sometimes highly controversial. In fact, behavioral genetics is marked by two epistemological eras, the genomic era that began in the 1980s and the postgenomic era that began by the early 2000s. The results provided by all these researches lead to one conclusion, the theoretical and technical approaches of the genomic era is insufficient to show the complexity of developmental phenomena associated with behaviors. The postgenomic era attempts to correct the weaknesses of the previous era. Thus, developmental biology comes back in the foreground and the necessity of this return has been defended by a major philosophical theory born in 1990, the Developmental Systems Theory. The postgenomic era is also characterized by a theoretical and experimental pragmatic pluralism. The complexity of the developmental patterns of behaviors is recognized and tends to be assumed. The latest results produce by researches on IQ, aggressive behaviors, addiction and sexual orientation illustrate these epistemological changes. The opposition between nature and nurture fails to properly apprehend the developmental dynamism of behavioral phenotypes. / Doctorat en Philosophie / info:eu-repo/semantics/nonPublished Sciences humaines Philosophie de la religion Behavior genetics -- Philosophy Developmental biology -- Philosophy Human behavior -- Philosophy Eugenics -- Moral and ethical aspects Comportement humain -- Philosophie Génome humain -- Aspect moral Eugénisme -- Aspect moral nature humaine développement/ eugenism homosexualité eugénisme development human nature homosexuality
405	Emergence de concepts multimodaux : de la perception de mouvements primitifs à l'ancrage de mots acoustiques / The Emergence of Multimodal Concepts : From Perceptual Motion Primitives to Grounded Acoustic Words Mangin, Olivier 19 March 2014 (has links) Cette thèse considère l'apprentissage de motifs récurrents dans la perception multimodale. Elle s'attache à développer des modèles robotiques de ces facultés telles qu'observées chez l'enfant, et elle s'inscrit en cela dans le domaine de la robotique développementale.Elle s'articule plus précisément autour de deux thèmes principaux qui sont d'une part la capacité d'enfants ou de robots à imiter et à comprendre le comportement d'humains, et d'autre part l'acquisition du langage. A leur intersection, nous examinons la question de la découverte par un agent en développement d'un répertoire de motifs primitifs dans son flux perceptuel. Nous spécifions ce problème et établissons son lien avec ceux de l'indétermination de la traduction décrit par Quine et de la séparation aveugle de source tels qu'étudiés en acoustique.Nous en étudions successivement quatre sous-problèmes et formulons une définition expérimentale de chacun. Des modèles d'agents résolvant ces problèmes sont également décrits et testés. Ils s'appuient particulièrement sur des techniques dites de sacs de mots, de factorisation de matrices et d'apprentissage par renforcement inverse. Nous approfondissons séparément les trois problèmes de l'apprentissage de sons élémentaires tels les phonèmes ou les mots, de mouvements basiques de danse et d'objectifs primaires composant des tâches motrices complexes. Pour finir nous étudions le problème de l'apprentissage d'éléments primitifs multimodaux, ce qui revient à résoudre simultanément plusieurs des problèmes précédents. Nous expliquons notamment en quoi cela fournit un modèle de l'ancrage de mots acoustiques / This thesis focuses on learning recurring patterns in multimodal perception. For that purpose it develops cognitive systems that model the mechanisms providing such capabilities to infants; a methodology that fits into thefield of developmental robotics.More precisely, this thesis revolves around two main topics that are, on the one hand the ability of infants or robots to imitate and understand human behaviors, and on the other the acquisition of language. At the crossing of these topics, we study the question of the how a developmental cognitive agent can discover a dictionary of primitive patterns from its multimodal perceptual flow. We specify this problem and formulate its links with Quine's indetermination of translation and blind source separation, as studied in acoustics.We sequentially study four sub-problems and provide an experimental formulation of each of them. We then describe and test computational models of agents solving these problems. They are particularly based on bag-of-words techniques, matrix factorization algorithms, and inverse reinforcement learning approaches. We first go in depth into the three separate problems of learning primitive sounds, such as phonemes or words, learning primitive dance motions, and learning primitive objective that compose complex tasks. Finally we study the problem of learning multimodal primitive patterns, which corresponds to solve simultaneously several of the aforementioned problems. We also details how the last problems models acoustic words grounding.

406	Barriers and bridges: interdisciplinary collaboration in addiction and mental health care Mitchell, Amber Risha Turner 19 December 2009 (has links) The objective of this thesis is to explore the factors that enhance collaboration in the interdisciplinary environment of front-line addiction and mental health care. This research will explore these factors by posing the question, What do mental health and addiction professionals report as determining the success of an Inter-Disciplinary Collaborative environment? Using McCracken‘s Long Interview (1988) and principles drawn from Flanagan‘s Critical Incident Technique (1954) the participants discuss their experiences with collaboration in the interdisciplinary environment of integrated addiction and mental health care. The findings are presented according to three overarching themes: 1) Interpersonal and Group Relations, 2) Organizational Supports, and 3) Challenges / Sources of Conflict. Finally, a dispute resolution perspective is taken in order to discuss the findings according to implications for practice, dispute resolution, and leadership and policy. conflict inter-group dispute resolution group interprofessional multidisciplinary concurrent collaboration cooperation
407	Exploring the feasibility of using tabletop displays for construction design meetings Chakrabarty, Subhanil 24 March 2011 (has links) We have investigated the feasibility of using digital tabletop displays during design team meetings to improve access to design information. To achieve this goal, we have applied various design guidelines for tabletop interface design and requirements for digital meeting scenarios in order to implement design ideas (in a prototype named Mozaic) that specifically cater to design team meetings. Mozaic intends to improve information retrieval and browsing activities during meetings thereby improving information access through a tile based layout, pop-up menu control and filtered list. We have evaluated the features of Mozaic through an exploratory study on a tabletop display (in comparison to a commonly used desktop software tool, which was also used on the tabletop) to evaluate various design ideas and ferret out design ideas for future iterations of Mozaic. We present the result of this study as observations and user feedback and discuss them in the light of interface development for design meeting situations.

408	Akciové cenové bubliny / Stock Price Bubbles Li, Xiaokun January 2010 (has links) Economic bubbles are playing an increasingly significant role in the current global economy. We believe these bubbles are to a certain extent dominating the real economy, and, therefore, research based on this specific economic phenomenon is becoming increasingly popular and important. The focus of this master's thesis is based upon analysis of stock price bubbles. This thesis contains author analyzed historical cases representative of stock price bubbles; summarizations of their traditional features; common factors causing their formation; and reasons leading to their bursting. Solutions to the dilemma of stock price bubbles are discussed in depth, and emphasis is placed upon clearly deciphering different theoretical approaches regarding this phenomenon-not only from the efficient market hypothesis viewpoint but also from the perspective of behavioral finance. The research contains testing and measuring methodologies of stock price bubbles, and the author's view concerning them is strongly supported by the results within the empirical data-testing chapter. Upon reading, one can expect to achieve a basic overview of this forefront science.
409	Ecological Influences on Weight Status in Urban African-American Adolescent Females: A Structural Equation Analysis Stanford, Jevetta 01 January 2012 (has links) The present study employed a quantitative, non-experimental, multivariate correlational research design to test a hypothesized model examining associative paths of influence between ecological factors and weight status of urban, African-American adolescent females. Anthropometric and self-report survey data of 182 urban, African- American adolescent females were collected during after-school programs, health and physical education classes, and community events in an urban area in northeast Florida. Descriptive analyses were conducted to characterize the study participants based upon their age, study setting, and weight status. A scale reliability analysis was conducted to assess the internal consistency reliability of the sample data using selected measures within the context of the study’s specific population and subsequently guided the structural equation model (SEM) analyses. The SEM path analysis was used to develop two measurement models to control for observed error variance for variables demonstrating poor internal consistency reliability (diet behaviors and nutrition selfefficacy) and a final structural model to test the associative paths of influence between latent (diet behaviors and nutrition self-efficacy) and manifest variables (teacher social support and friend social support) on weight status. The results of the path analysis indicated that both teacher social support and friend social support demonstrated a positive, indirect influence on child weight status through nutrition self-efficacy and diet behaviors following two different and specific paths of influence. Diet behaviors, in turn, demonstrated a positive, direct effect on child weight status. These findings provide clear implications for educational leaders that call for the integration of health behavior change theory into traditional education and leadership practice and actively addressing the childhood obesity epidemic in the school environment by implementing health behavior change strategies at various ecological environmental levels.

410	Mänskligt beteende - ett ofrånkomligt hot mot informationssäkerhet? Swartz, Erik January 2021 (has links) Information har idag kommit att bli så viktigt att det av många aktörer kallas för den nya digitala oljan, och med anledning av just detta är information idag en av de främsta tillgångar en organisation kan besitta. För att skydda informationen lägger organisationer massiva summor pengar på tekniska och fysiska åtgärder. Tillsammans med dessa åtgärder utfärdas även interna bestämmelser och riktlinjer för hur IT-system och information får eller inte får hanteras. Trots detta sker både intrång och andra säkerhetsrelaterade incidenter som kan härledas till mänskligt felaktigt beteende, eller den så kallade mänsklig faktorn. I den här uppsatsen har därför författaren gjort en djupdykning i ämnet för att studera vilka samband som kan finnas mellan beteendevetenskapliga teorier och efterlevnad av informationssäkerhet. Med kvalitativa metoder har bland annat litteraturstudier genomförts för att ta reda på vilka teorier som är mest relevanta i sammanhanget. Intervjuer har sedan nyttjats för att bredda författarens uppfattning om vilka faktorer som kan påverka mänskligt beteende. De personer som intervjuats har bland varit yrkesverksamma som säkerhetschefer, säkerhetskyddshandläggare och ledande forskare inom det specifika området.
