As preferências humanas de iluminação nos ambientes internos estão relacionadas inicialmente à satisfação de conforto luminoso a partir de exigências não somente visuais, mas fisiológicas de saúde, conforme os objetivos do projeto e atividades. Este trabalho aborda a percepção da iluminação natural e artificial complementar diurna, em ambiente de escritório com o objetivo de identificar preferências humanas pesquisadas em um mock up, modelo que reproduz o ambiente em escala real. A partir do entendimento do ato de ver, procuramos mostrar como a luz pode alterar a percepção do espaço, revelar os contornos, alterar limites, escalas, cores e texturas das superfícies. A relação entre luz e espaço determina a nossa percepção visual do mundo que nos cerca e da maneira que o sentimos. Procuramos redefinir então o conceito de conforto visual, ampliando-o para conforto luminoso, que passaria a abordar aspectos não visuais da luz que exercem grande influência no metabolismo humano, através da regulação dos ritmos circadianos com desdobramentos na saúde, bem-estar e produtividade. Para a pesquisa experimental, o mock up foi construído simulando um ambiente de trabalho com mobiliário e objetos, onde as aberturas projetadas poderiam ser fechadas ou liberadas criando tipologias distintas de captação de luz, seja lateral e/ou zenital. Ao entrevistado, caberia escolher entre duas situações em que as variáveis consideradas foram: as posições e dimensões das aberturas para luz natural e inserção de luz artificial complementar. Para validação dos modelos e comparação dos resultados obtidos, trabalhamos com outros modelos, desde a maquete, à simulação computacional através do software Agi-32 e fotografias do ambiente em situações similares às pesquisadas no mock up. Os resultados confirmaram a hipótese de que as preferências de iluminação em escritórios estão relacionadas à satisfação do conforto luminoso em função das tarefas, incluindo aqui também a distribuição da luz, dos contrastes obtidos nas superfícies e plano de trabalho, ou distribuição harmoniosa de luminâncias. Nas situações em que a luz natural atende aos requisitos quantitativos da tarefa e conforto luminoso, ela é preferida em relação à luz artificial. A pesquisa pretende contribuir para trabalhos futuros, acerca do estudo da percepção da luz, relacionando atividade ou função do espaço, intenções do projeto, qualidade da luz arquitetural e luz tarefa. / The aim of this project is the study of people\'s preferences in interior lighting. These are initially connected to a sense of satisfaction and comfort, stemming from demands that are not only visual but also physiological. This study considers the perception of natural and complementary artificial daylight in an office environment and aims to identify preferences by means of a life size mock up model. Starting from the understanding of the act of seeing, the study seeks to show how light can change our perception of space, reveal outlines , and change limits, scale, colours and textures of surfaces. The relationship between light and space determines our visual perception of the world around us. This study seeks to redefine the concept of visual comfort, expanding it to the notion of luminous comfort. This notion comes to consider non visual aspects of light which greatly influence human metabolism by regulating our biorhythms, which in turn have ramifications for our health, well-being and productivity. In order to conduct our research a mock up was built which simulated a work environment. The space contained furniture and objects and openings could be closed or opened to create distinct types of lighting, whether lateral or zenithal. The subjects interviewed simply had to choose between tow situations. Variables considered were the aperture and position of the openings allowing in natural light and the use of complementary artificial light. To validate the models, results were compared with other models, computer simulations using Agi-32 software and photographs of the environment in similar situations as those investigated in the mock up. The results confirm the hypothesis that preferences for lighting in offices are connected to fulfilling the need for luminous comfort. Preferences are also linked to task lighting, including the distribution of light, contrast on surfaces and the work area as well as the harmonious placement of light sources. In those situations where natural light meets the quantitative demands of the lighting task luminous comfort is achieved and this is preferred to artificial light. The research contributes to future studies in how perception of light is linked to activity or the function of space. It also contributes to studies on the quality of light and task lighting.

Recognising Acute Deterioration: Active Response (RADAR) is a simulation based teaching session using simulated patients to portray acutely unwell adult hospital patients. The genesis, development and progress of RADAR will be discussed along with the findings of questionnaires and focus groups from two further cycles of action research. Readers will become aware of the impact which RADAR makes to the evidence and learning surrounding the recognition and assessment of clinical deterioration in adult hospital patients. The study investigated the impact of simulation on medical students’ confidence in recognising and responding to clinical deterioration in adult hospital patients using simulation, simulated patients and moulage (make-up).

As tecnologias telemáticas se desenvolveram, trouxeram novas formas de viver e se incorporaram ao cotidiano de indivíduos e empresas. No mundo contemporâneo, a comunicação à distância tem-se mostrado importante instrumento para o desenvolvimento dos países, organizações públicas e empresas, integrando diferentes comunidades e agilizando processos de decisão. No cenário de desenvolvimento dessas tecnologias, a videoconferência é a ferramenta que agrega a maior quantidade de informações para um encontro mediado por tecnologia. Ela potencializa a comunicação pela integração das tecnologias de áudio, vídeo, e informática. Por outro lado, as reuniões realizadas por videoconferência ainda têm um potencial limitado de comunicação, demandando estudos para seu aprimoramento. A Ergonomia foca seus estudos nos aspectos físicos, psíquicos e cognitivos, intervindo nas relações entre o homem, seu trabalho e meio físico. Por isso, apresenta-se como um instrumento adequado de intervenção para melhorar a comunicação de uma reunião por videoconferência. Iniciamos esta tese mostrando como as tecnologias de comunicação fizeram parte da vida cotidiana dos povos ocidentais e como as tecnologias de videoconferência se situam enquanto instrumento de comunicação empresarial. Em seguida, realizamos uma comparação entre os aspectos ergonômicos de uma reunião presencial e os de uma reunião em videoconferência. Identificamos os ruídos provocados pela utilização dos sistemas de videoconferência e verificamos que grande parte deles diz respeito à questão da ambientação da interface de comunicação no espaço. Mostramos ainda como diversos tipos de interface de comunicação (pinturas, panoramas, espelhos, cinema, fotografia e desenho animado) foram utilizados para ambientar o espaço com a interface de comunicação. Exploramos as várias formas de intervenção no espaço, buscando identificar os aspectos ergonômicos que valorizam a informação comunicada e os elementos do contexto espacial que fazem com que esta se potencialize. A partir desses estudos, propomos critérios a que uma interface de comunicação deveria atender a fim de valorizar a comunicação da reunião por videoconferência. Indicamos ainda uma alternativa tecnológica para cada um dos critérios especificados. Concluímos com uma discussão sobre os caminhos abertos para novas pesquisas em diversas áreas do conhecimento, e com uma reflexão sobre a influência da incorporação destes no desenvolvimento dos projetos de arquitetura. / In contemporary time, distant communication has been an important tool for business development, since it permits people from all over the world to meet quickly by using telematic technologies. Videoconference has been used as an ordinary tool for that purpose, which provides the sharing of audio, video and computer information. Unfortunately, videoconference communication is a poor means for distance meetings and its efficiency must urgently be improved. Besides, ?the central approach of human factors is the systemic application of relevant information about human characteristics and behavior to design the man-made objects, facilities and environments that people use?1. Therefore, it is a relevant instrument for achieving more efficient distant meeting. Firstly, we give an overview of communication technologies applied to business, identifying how videoconferencing systems have been used as a corporative communication instrument. Secondly, we compare live meetings to videoconference ones, searching for differences in human factors that indicate loss of information caused by the use of a communication system. Thirdly, we demonstrate how different communication interfaces produced by man were used to integrate the perception of the physical space and the virtual space shown on them. Consequently, we propose a list of criteria that an interface should meet, in order to improve human factors in distant meetings through a videoconference system. Finally, we provoke a discussion about other possible applications and we also examine how architecture can be modified by considering those criteria in regard to its design.

Student Number : 9802206M - MA dissertation - School of Psychology - Faculty of Humanities / Before this study took place, the social psychology perspective of Attribution theory was yet to be fully utilised in South African research within the maintenance error landscape. Attributional approaches see the person on the street operating like a scientist, obtaining information from his or her social surroundings and discerning the causes and consequences of ongoing behavioural and environmental events (Harvey et.al.,1976). It is very possible that due to the unique South African socio-political and economic landscape, strongly influenced by Apartheid, new combinations of known and unknown error attributions are at play, that are unique to this landscape and have not yet been studied or uncovered. Thus, a better understanding of the South African landscape, through a study such as this, could have serious cost benefits to maintenance companies, benefits to staff in terms of reduced risk of injury, as well as form the basis of improved policies, procedures and equipment. Twenty-five team leaders and 125 minor maintenance staff at a South African Aircraft Maintenance Company formed the population group from which the sample for this study was drawn. Within each group, 5 individuals were interviewed on a personal basis. Further, for each group, one focus group was carried out consisting of two and four individuals respectively. The individuals who participated in the focus groups were different to those who participated in the interviews. In total 28 percent of team leaders participated in the study and 7 percent of maintenance staff, which calculates to just over 10 percent of minor maintenance employees at the organisation involved. The Qualitative data acquired through this in-depth interview and focus group discussion process, and subsequent transcription was coded and analysed using Thematic Content Analysis. Content analysis is a research technique for making replicable and valid inferences from data to their context (Krippendorf, 1980). The discussion of primary error attributions comparing maintenance staff and team leaders, focussed on the predominant primary error attribution theme and related attributions under the descriptor Organisational Culture which included both the dimensions of employee motivation and managerial culture. Finally, results of secondary error attributions comparing maintenance staff and team leaders raised the discussion around the theme, Tools and Equipment. This research is an exploratory study that brings together the field of attribution theory and maintenance error. Its main strength is that it provides a theoretical framework, upon which is based a methodology that explores the primary and secondary error attributions made by employees for maintenance errors in their work environment. In other words, it is felt that this methodology can be implemented in a range of maintenance environments to unearth the error attributions of staff in that environment. Information such as this is very beneficial to companies and organisations in their planning, strategising, problem solving and general organisational development.

abstract: Human-robot interaction has expanded immensely within dynamic environments. The goals of human-robot interaction are to increase productivity, efficiency and safety. In order for the integration of human-robot interaction to be seamless and effective humans must be willing to trust the capabilities of assistive robots. A major priority for human-robot interaction should be to understand how human dyads have been historically effective within a joint-task setting. This will ensure that all goals can be met in human robot settings. The aim of the present study was to examine human dyads and the effects of an unexpected interruption. Humans’ interpersonal and individual levels of trust were studied in order to draw appropriate conclusions. Seventeen undergraduate and graduate level dyads were collected from Arizona State University. Participants were broken up into either a surprise condition or a baseline condition. Participants individually took two surveys in order to have an accurate understanding of levels of dispositional and individual levels of trust. The findings showed that participant levels of interpersonal trust were average. Surprisingly, participants who participated in the surprise condition afterwards, showed moderate to high levels of dyad trust. This effect showed that participants became more reliant on their partners when interrupted by a surprising event. Future studies will take this knowledge and apply it to human-robot interaction, in order to mimic the seamless team-interaction shown in historically effective dyads, specifically human team interaction. / Dissertation/Thesis / Masters Thesis Engineering 2019

Diagnostic errors cause significant patient harm and occur among 15 percent of all clinical diagnoses, but research has yet to effectively target, prevent, and mitigate diagnostic errors from occurring. So far, literature has examined how diagnostician decision-makers perform and reach a clinical diagnosis individually. However, the impact of team-based activities on diagnosis is unknown. The purpose of this study is to describe provider perception on how providers come together as a team in order to complete a clinical diagnosis. As a qualitative descriptive study with overtones of grounded theory, 18 semi-structured interviews of medical intensive care unit providers were audio-recorded, transcribed, and coded generating themes of diagnostic teamwork structure and functioning. Diagnostic teams are described using themes of inter-professional and intra-professional teamwork among roles with and without diagnostic team identity. Novel approaches to diagnostic error research, practice implications for current providers, and applications provided for improving education and team training. By providing preliminary insights on the role of teamwork in diagnostic decision-making, this study may assist future studies that improve diagnostic teamwork and prevent diagnostic errors.

This research compares methods for measuring pilot mental workload (MWL) from the electrocardiogram (ECG) signal. ECG-based metrics have been used extensively in MWL research. Heart rate (HR) and heart-rate variability (HRV) exhibit changes in response to varying levels of task demand. Classical methods for HRV analysis examine the ECG signal in the linear time and frequency domains. More contemporary research has advanced the notion that nonlinear elements contribute to cardiac control and ECG signal generation, spawning development of analytical techniques borrowed from the domain of nonlinear dynamics (NLD). Applications of nonlinear HRV analysis are substantial in clinical diagnosis settings; however, such applications are less frequent in MWL research, especially in the aviation domain. Specifically, the relative utility of linear and non-linear HRV analysis methods has not been fully assessed in pilot MWL research. This thesis contributes to aforementioned research gap by comparing a non-linear HRV method, utilizing transition probability variances (TPV), to classical time and frequency domain methods, focusing the analysis on sensitivity and diagnosticity. ECG data is harvested from a recent study characterizing spatial disorientation (SDO) risk amongst three candidate off-boresight (OBS) helmet-mounted display (HMD) symbologies in a tactically relevant live-flight task. A comparative analysis of methods on this dataset and supplemental workload analysis for the HMD study are presented. Results indicate the TPV method may exhibit higher sensitivity and diagnosticity than classical methods. However, limitations of this analysis warrant further investigation into this question.

Research on infidelity has suffered from inconsistency in how infidelity has been operationalized across studies. This study was designed to advance methodological considerations for defining infidelity and identifying offending spouses. A subjective definition of infidelity was obtained from each respondent via both closed- and open-ended items. The open-ended responses were applied to explore the definition of infidelity. Additionally, an indirect questioning method was adopted to identify offending spouses according to their own subjective definitions of cheating and test the effectiveness of this approach relative to direct questioning for identifying offending spouses. Furthermore, gender differences in acknowledging infidelity through both direct and indirect approaches in general as well as across the four self-defined categorical infidelity were examined. A community sample of 465 married or divorced individuals anonymously completed the survey via MTurk. Results showed two defining characteristics of infidelity that cut across modes of infidelity (sexual, emotional, computer-mediated, and solitary) were that infidelity occurs outside the relationship and without consent. The definition of infidelity of infidelity provided in response to an open-ended inquiry tended to be shorter among offending spouses—especially male offending spouses—than among non-offending spouses. More offending spouses were found via the indirect (42.9%) approach than the direct approach (12.7%), and more men than women acknowledged engaging in infidelity behaviors according to both the direct (16.6% vs. 9.1%) and indirect (48.2% vs. 38.0%) approaches. That said, gender-based statistical differences in propensity to commit self-defined infidelity were only found in sexual and computer-mediated forms of infidelity; propensity to commit self-defined emotional and solitary infidelity did not statistically differ between men and women; in all cases, however, gender differences were small. Results suggested that the indirect approach is better than direct questioning for identifying infidelity behaviors; the indirect approach elicited less social desirability bias. Implications for research and clinical practice are provided.

Although humans engage in committed, long-term pair bonds, many romantic relationships end because one partner no longer desires to be in the relationship. Much of the literature on romantic relationship psychology and behavior has focused on mechanisms related to maintaining a partner. Mate retention behavior functions to deter romantic partners from defection and fend off potential alternative partners. However, when individuals are in a relationship where the costs of remaining in the relationship outweigh the benefits of leaving the relationship, mate expulsion, not retention, may be the desired goal. The present thesis examines mate expulsion behavior and psychology with the goal of developing a measure of mate expulsion to parallel a widely-used measure of mate retention. In my pilot studies, participants (n= 103) nominated behaviors and tactics that people use to reduce commitment in and terminate relationships. I identified 168 unique mate expulsion behaviors from these nominations that fell in the following four categories:signaling a lack of commitment to their partner, signaling their availability to others potential partners, extracting oneself from shared relationship commitments or investments, and reducing dependency on one’s partner or relationship. A separate set of participants (n= 131) rated the frequency with which they had used the behaviors, or had seen their partner use the behaviors, in their actual past break-ups. This procedure reduced the list of utilized tactics to 51 mate expulsion behaviors. A third set of participants (n = 290) in relationships rated the frequency with which they engaged in the 51 behaviors in their current relationship and completed measures of relationships satisfaction and mate retention. As expected, mate expulsion was negatively related to relationship satisfaction. I conducted a preliminary factor analysis using these data, which revealed 7 clusters of mate expulsion behavior: For my thesis, I collected a larger, less gender-biased sample to 1) confirm the factor structure of the mate expulsion inventory and 2) examine the relationships between the mate expulsion inventory, mate retention, and relationship satisfaction. Participants (n = 410) completed the Couple Satisfaction Index-16, the Mate Retention Inventory Short-Form, and the Mate Expulsion Inventory. Mate expulsion was again negatively correlated with relationship satisfaction and a similar, small positive correlation was replicated between mate expulsion and mate retention. My hypothesized model for the confirmatory factor analysis was acceptable but not excellent. I attempted several modifications to improve the measures of fit. Ultimately, the best model included the removal of specific items and eliminating a latent variable. This thesis produced a concise list of mate expulsion behaviors and has expanded on the literature of mating psychology in respect to relationship termination. These results suggest human mating psychology may include mechanisms that function to terminate and maintain relationships.

Industry and research have shown that, in addition to the knowledge, skills, and abilities of individuals, other factors play an influential role in the efficiency of a team. The research questions for this study examined the influence of functional characteristics, defined as the cognitive and evaluative processes such as intentions, emotions, planning, and perception that influence decisions, on team outcomes and the time it takes to complete a task. Using a quantitative, experimental research design, the research questions were grounded in personality systems interactions as the theoretical framework. Analysis of variance was applied to evaluate the hypotheses with an independent measure used to analyze 114 student participant responses to an online assessment and a team task. Results of a test of between-subjects effect identified their functional characteristic levels. Findings displayed statistical significance with main effect for (a) action orientation and (b) the time it takes to complete an assigned task, F(2, 57) = 3.24, p = 0.047. These findings could serve to decrease organizational costs such as those associated with human resource selection processes, team training, or team performance outcomes. The findings support positive social change by increasing social and behavioral psychologists' understanding of human-to-human behavioral interactions and the influence of functional characteristics on organizational teams.
