The comparative Situation Awareness performance of older (to younger) drivers

Key, C. E. James January 2016 (has links)
The overall aim of this thesis is to corroborate whether the Situation Awareness (SA) of older drivers is deficient to that of younger driving groups, due to the onset of age-related cognitive decrements. This is important to ascertain due to a presumed linkage between the concept and accident causation. In addition, the research undertaken to date to investigate this linkage has exclusively utilised rather artificial driving simulators and simulations. Thus there is a need for data from more ecologically valid methods. The research studies reported here have sought to preference on-road assessments (of different complexity), and to capture what information was selectively perceived, comprehended and reacted to; rather than, as in previous work, what was recalled. To achieve this, a Think aloud methodology was chosen to produce narratives of a driver s thoughts. This method was advantageously unobtrusiveness, but also flexible - it could additionally be used to compare an individual's SA to a driving performance measure, Hazard Perception. The driving-based studies undertaken found that for a relatively non-taxing route, an older driver group could produce cohesive awareness in parity with a younger driver group. However, the concepts from which that awareness was based upon drew more on general, direction based, concepts, in contrast to the younger group s focus on more specific, action based, concepts, and rearward and safety-related cues. For a more cognitively taxing route, the younger group produced significantly higher (p < 0.024) individual SA-related scores than their older counterparts. But the concepts/cues both groups relied upon remained similar - particularly in regards to the ratio of those indicative of a rearward and/or a safety-related focus. In a video-based study, however, and in contrast, the older driver group s SA scores improved sufficient to outperform a younger group, but, despite this, not for video-based scores indicative of Hazard Perception (HP). In this latter regard, age-related decrements appeared to be more influential, as the older group felt they were under time pressure during a HP test. However, the difficulty this presented appeared to advantageously bring more attention and effort to the task, which were argued as important factors for the uplift in their SA scoring. The thesis also showed that older groups judgement of the actual complexity of a driving task could potentially be deficient to that of younger driver groups. This could cause problems as incorrect perceptions could deflate the relevance and cohesiveness of information being processing. In contrast, the perceived complexity of a task could bring a rise or fall in SA score for both groups. Such results raised questions as to the impact of cognitive decrements, relative to task difficulty and related effort whilst driving. It also provided evidence that Situation Awareness, rather than being uniformly good or bad, could, like any other psychological construct, be prone to change. These aspects were drawn together in a proposed model of driving SA.

Bara ett spel till : Tre delstudier om pengaspel och spelberoende

Carlsén, Anton January 2018 (has links)
Cirka 2 % av Sveriges befolkning beräknas ha ett spelberoende om pengar. Trots ökad medvetenhet om risken att utveckla spelberoende fortsätter spelandet med stora summor. Syftet med delstudie 1 var att undersöka upplevelser och erfarenheter av pengaspel. I en enkät berättade 29 högskolestudenter om erfarenheter av pengaspel. En tematisk innehållsanalys resulterade i tre teman: positiva upplevelser (vinst, nöje), negativa upplevelser (förlust, spelberoende, sociala problem, spelskulder, ointressant) och neutral upplevelse (kontroll). Syftet med Delstudie 2 och 3 var att undersöka spelberoendets effekt på livssituationen utifrån två olika perspektiv. Två män med tidigare spelberoende respektive två kvinnliga samtalsterapeuter intervjuades om sina upplevelser av spelberoendets effekt på livssituationen. En tematisk innehållsanalys resulterade i 13 respektive nio teman som besvarade tre frågeställningar inom vardera delstudie. Spelberoendeupplevelserna i Delstudie 2 innehöll: orealistiska målsättningar, tankefällor, återfall och ökad självinsikt. Spelberoendeupplevelserna i Delstudie 3 innehöll: skeva uppfattningar, storvinster, depression och skulder. Sammantaget var deltagarna negativa till pengaspel.

Sensibilidade à situação em sistemas educacionais na web

Fleischmann, Ana Marilza Pernas January 2012 (has links)
Adaptação e sensibilidade ao contexto andam juntos em diferentes tipos de aplicações. A sensibilidade ao contexto não necessariamente implica em adaptação, mas para que um sistema sensível ao contexto possa guiar uma adaptação efetiva, precisa acompanhar a ocorrência de determinados eventos no sistema e reagir de forma adequada a estes eventos. Este caráter adaptativo tem sido buscado em sistemas Web, de forma a se comportarem de maneira personalizada em atendimento às necessidades particulares do usuário. Dentre uma diversidade de sistemas Web que se propõem a apresentar como diferencial caráter sensível ao contexto do usuário, este trabalho estuda um domínio de aplicação específico: os sistemas de educação adaptativos baseados na Web. Este domínio se mostra crítico, pois necessita ser personalizado tendo em vista um usuário não comum e com uma série de particularidades que devem ser levadas em conta: o aluno. O objetivo principal deste trabalho é apresentar uma solução para o problema da adaptação de ações sensíveis às situações vivenciadas por alunos em um sistema de educação adaptativo baseado na Web. Este problema engloba diversas questões que são atualmente foco de pesquisa em áreas relacionadas à sensibilidade ao contexto, entre elas: (i) as formas de obtenção dos dados relativos ao contexto do aluno; (ii) a análise dos diferentes grupos e modelos de contexto que descrevem a situação em si, vivenciada pelo aluno no momento atual; (iii) as formas de avaliação e relacionamento dos dados de contexto do aluno, de forma a permitir inferência de sua situação atual. Para este fim, foi desenvolvida uma solução capaz de auxiliar o funcionamento de sistemas de educação adaptativos, de forma a apresentarem caráter reativo à situação vivenciada pelo aluno. A solução desenvolvida consiste de um módulo de sensibilidade à situação, construído com o objetivo de analisar as diversas particularidades existentes no cotidiano atual do aluno, se mantendo útil a ele independentemente do seu local atual, do dispositivo computacional utilizado e da tarefa em curso, respeitando as características individuais do aluno. De acordo com a situação detectada, ações de adaptação são fornecidas à mídia adaptativa, com intuito de prover uma experiência educacional voltada às necessidades reais do aluno. Ao final, o funcionamento da solução proposta foi simulado em conjunto a um ambiente de ensino real, de forma a verificar sua aplicabilidade prática. / Adaptation and context awareness walk together in different kinds of applications. Context awareness doesn’t imply necessarily in adaptation, but an adaptive system in order to guide an effective adaptation need to be aware about the occurrence of specific events and properly react to them. This adaptive character has been looked in web systems, in order to behave in a personalized way in attending the particular needs of the user. Among a variety of web systems that propose to present a context aware character, this work presents a case study in a specific application domain: web-based adaptive educational systems. This area is critical because the system needs to be customized in order to attend a not common user, with a variety of particularities that should be taken into account: the student. The main objective of this work is to present a solution to the problem of adaptation of situation-aware actions lived by students in a web-based adaptive educational system. This problem involves several issues that are currently focus of research in areas related with context-awareness, like: (i) the ways of obtaining student’s context data, which often lead to uncertain and ambiguous analysis (ii) the analysis of different groups and context models that describe the situation itself, experienced by the student at the present time, (iii) the ways of evaluating and correlating student’s context data, to allow the inference of their current situation. To this end, we developed a solution capable to assist the functioning of adaptive educational systems; in order to present a reactive character to the situations lived by the student. The solution consists on situation-aware module which aiming at evaluating the several particularities of the student’s actual routine to remain useful to him, regardless of his current location, the computing device used, day of week and the ongoing task, respecting the individual characteristics of the student. According to the detected situation, adaptive actions are presented to the adaptive hypermedia, aiming at providing a better educational experience to the student. At the end of this work, the solution developed is tested with a real e-learning environment to verify its practical appliance.

The Effect of Situation Presence Assessment Method (SPAM) on Air Traffic Control Students' Workload and Performance in High-Fidelity Simulations

January 2016 (has links)
abstract: This study examined the impact of Situation Presence Assessment Method (SPAM) administration on air traffic control (ATC) students’ task workload and performance in high-fidelity ATC simulations. ATC students performed high-fidelity en-route simulations in two conditions: baseline conditions (without SPAM questions) and SPAM conditions. The data collected show that while workload in the two conditions were not significantly different, there was a trend of higher mental workload in SPAM conditions than in baseline conditions. Performance immediately following SPAM questions was revealed to be poorer than that preceding the SPAM questions and that over the equivalent time periods in the baseline conditions. The results suggest that a "Ready" signal before a SPAM question may not be enough to eliminate the impact of SPAM administration on ATC students’ workload and performance in high-fidelity en-route simulations. / Dissertation/Thesis / Masters Thesis Technology 2016

Traffic Light Status Detection Using Movement Patterns of Vehicles

January 2016 (has links)
abstract: Traditional methods for detecting the status of traffic lights used in autonomous vehicles may be susceptible to errors, which is troublesome in a safety-critical environment. In the case of vision-based recognition methods, failures may arise due to disturbances in the environment such as occluded views or poor lighting conditions. Some methods also depend on high-precision meta-data which is not always available. This thesis proposes a complementary detection approach based on an entirely new source of information: the movement patterns of other nearby vehicles. This approach is robust to traditional sources of error, and may serve as a viable supplemental detection method. Several different classification models are presented for inferring traffic light status based on these patterns. Their performance is evaluated over real-world and simulation data sets, resulting in up to 97% accuracy in each set. / Dissertation/Thesis / Masters Thesis Computer Science 2016

Dificuldades que não estão relacionadas apenas às limitações auditivas, visuais, mentais, físicas e/ou motoras, mas principalmente àquelas imposta pela sociedade e pelo capital e se manifesta muitas vezes através da segregação, do estigma e do preconceito. Nesse estudo limitamo-nos a estudar os portadores de deficiência física, buscando descrever e discutir as condições em que eles vivem. Essa pesquisa foi desenvolvida na cidade de Botucatu – São Paulo. Inicialmente foi feito um inquérito em 25% dos domicílios da área urbana de Botucatu, para localizar os portadores de deficiência física. Identificados os endereços, selecionamos apenas os que residem na área do Centro Saúde Escola. Fizemos uma caracterização biomédica e social dos portadores de deficiência física e suas famílias, utilizando um roteiro com questões abertas e fechadas. Foram entrevistadas 82 famílias e 93 pessoas portadoras de deficiência física. Observamos que no município de Botucatu há uma maior prevalência de pessoas portadoras de deficiência física em áreas de alta exclusão social. Em relação às pessoas portadoras de deficiência física temos que 51% são do sexo masculino. A idade média é de 49 anos, 36,3% tem mais de 60 anos. A escolaridade média é 4,2 anos de estudos. A maioria é aposentado, pensionista ou inativo (71%). Apenas 14,5% estão ocupados e destes, 45,5%, estão inseridos em atividades predominantemente manuais não especializadas. O rendimento médio é de 0,9 salários mínimos e 39,2% não possuem nenhuma fonte de renda.

Such difficulties are not only related to auditory, visual, mental, physical and/or motor limitations but mainly to those established by society and capital and most of the times it is demonstrated through segregation, stigma and prejudice. Physically disabled people were the aim of this study and their living conditions were discussed and described. This research was carried in Botucatu – São Paulo. At first, a survey was performed in 25% of houses in the urban area of Botucatu to identify the physically disabled people. When the addresses were identified, one selected only the ones, which lived at “Centro de Saúde Escola” vicinities. A biomedical and social characterization was performed on physically disabled people and their families, following open and closed questions round. One observed that in Botucatu there is a higher prevalence of physically disabled people among high social excluded ones. Related to physically disabled people, 51% are male. Average age is 49 years old, 36.3% is more than 60 years old. Average education is 4.2 years of study, most of them are retired, pensioner or inactive. (71%). Only 14.5% have an occupation and from these 45.5% are inserted in predominantly non-specialized manual activities. Average income is 0.9 minimum wages and 39. 2% do not have any income. The family of physically disabled people has an average of 3.7 people; 57.5% of families are cellular like, and from these, 18.8% are extended families, which are being dispersed. According to the scale used by Seade Foundation, 17% of families are considered wretched, 71% poor and 12,1% not poor.

História e ontologia na obra de Jean-Paul Sartre / History and ontology on Jean-Paul Sartres work

Igor Silva Alves 10 May 2017 (has links)
Nesta pesquisa, busca-se analisar alguns aspectos da vinculação entre dois momentos da obra de Jean-Paul Sartre a partir da relação entre ontologia e história. O primeiro momento, marcado pela ontologia fenomenológica de O ser e o nada, apresentaria estruturas caracterizadas por uma a-historicidade; o segundo momento, marcado principalmente pela aproximação do marxismo e um grande peso dado à história, encontra-se principalmente em Questão de método e Crítica da razão dialética. Ao contrário das interpretações que afirmam a incompatibilidade entre esses dois momentos da obra de Sartre, mostra-se ao longo do texto que as estruturas da ontologia fenomenológica, se não apresentam uma formulação sobre a história, são uma abertura para ela, pois descrevem um processo de totalização de si do sujeito que o lança em uma totalização de totalizações a qual, por sua vez, é o próprio processo histórico. / This research aims to analyze some aspects of the link between two moments of Jean-Paul Sartre\'s philosophy regarding the relation between ontology and history. The first moment, marked by the phenomenological ontology of Being and Nothingness, would present structures characterized by a-historicity; the second moment, marked by an approach of Marxism and by a great weight being ascribed to history, is found mainly in Question of method and in Critique of dialectical reason. Contrary to the interpretations that sustain the existence of an incompatibility between these two moments of Sartre\'s thought, this work argues that the structures of phenomenological ontology, if they do not present a formulation about history, they nonetheless hold an opening towards it, since they describe a process through which the subject carries out a totalization of herself that throws her into a totalization of totalizations which, in turn, is the historical process itself.

O paradoxo da liberdade: Psicanálise e História em Sartre / The paradox of freedom: Psychoanalysis and History in Sartre

Renato dos Santos Belo 19 June 2006 (has links)
Logo após a sua publicação, 1943, a obra O Ser e o Nada de Sartre foi alvo de comentários críticos que apontavam seu caráter idealista. Essas leituras enfatizavam a incompatibilidade entre a afirmação sartriana de uma liberdade absoluta do homem e as condições históricas que acabariam por determiná- lo. Quando Sartre publicou em 1960 a sua Crítica da Razão Dialética (\"encontro\" com o marxismo), tudo se passou como a confirmação do idealismo presente em O Ser e o Nada, a ponto de se operar a divisão de seu pensamento em antes e depois da Crítica. Sartre, no entanto, ao defender o absoluto da liberdade afirma também que não há liberdade sem situação. Tentaremos enfatizar essa difícil relação entre liberdade e situação a partir da apresentação da concepção sartriana de liberdade, bem como pelo exame da proposta psicanalítica de Sartre. / Right after its publication in 1943, Sartre\'s Being and nothingness has received critical commentaries that pointed out its idealistic character. These lectures emphasized the incompatibility between Sartre\'s assertion of man\'s absolute freedom and the historical conditions which would determine it. When Sartre publishes, in 1960, his Critique of dialectic reason (\"encounter\" with Marxism), everything is seen as the confirmation of the idealism of Being and nothingness, overcoming the division of his thought in before and after the Critique. However, when Sartre defends the absolute of freedom he also affirms that there is no freedom without situation. We will try to emphasize this difficult relation between freedom and situation through the presentation of Sartre\'s concept of freedom, as well as through the examination of his psychoanalytic proposal.
