A Biologia Molecular e a Biotecnologia e seus conceitos subjacentes estão inseridos no currículo escolar da educação básica e têm estado presentes na vida cotidiana dos estudantes, envolvendo a análise e tomada de decisão sobre aspectos éticos relacionados à produção e aplicação do conhecimento científico e tecnológico. As explicações de alguns fenômenos e processos relacionados a estes temas estão quase sempre no nível molecular e atômico, que é descrito e explicado com modelos conceituais e físicos, ou até mesmo imagens. À luz da Teoria dos Modelos Mentais de Johnson-Laird, as pessoas raciocinam através de modelos mentais, podendo utilizar outras formas de representações mentais como proposições e imagens. Nesse contexto propôs-se diagnosticar entre treze alunos dos cursos de Licenciatura em Ciências Exatas (LCE) e Bacharelado em Ciências Físicas e Biomoleculares (CFBio), ambos cursos da Universidade de São Paulo, quais as representações mentais que esses alunos possuíam sobre o tema proteínas, bem como a contribuição de uma sequência didática utilizando modelos táteis para o ensino e aprendizagem da estrutura e função de proteínas. Para tal, realizamos (a) uma entrevista com os alunos dos cursos mencionados (pré-teste), (b) dois cursos com duração de três dias para cada turma (LCE e CFBio) e (c) uma entrevista com os mesmos alunos transcorrida uma semana após a realização de cada curso (pós-teste). Os dados obtidos foram de três tipos: registros escritos (desenhos e/ ou esquemas); um ou mais modelos táteis montados com materiais de baixo custo; áudio e imagens oriundos das filmagens das entrevistas. Os registros escritos e os modelos táteis de cada aluno foram fotografados e os áudios das entrevistas transcritos, gerando um documento individual que possibilitou uma análise de conteúdo, permitindo a divisão da amostra em duas categorias: alunos modelizadores e não modelizadores, cada uma com subcategorias próprias. A detecção das representações mentais que os alunos possuíam antes e após o curso sinalizou que a contribuição da sequência didática aplicada no curso para o ensino/aprendizagem do tema proteínas foi positiva, promovendo o aumento do número de alunos modelizadores e possibilitando aos mesmos o aumento do nível de complexidade e sofisticação em suas representações externas (modelos táteis e desenhos) e a evolução e esclarecimento de conceitos antes não compreendidos. / The Molecular Biology and Biotechnology and its underlying concepts are embedded in the curriculum of basic education and have been present in the daily life of students, involving the analysis and decision making about ethical issues related to the production and application of scientific and technological knowledge. The explanations of some phenomena and processes related to these themes are almost always in atomic and molecular level, which is described and explained with physical and conceptual models, or even images. In light of the mental models theory of Johnson-Laird, people reason through mental models and may use other forms of mental representations as propositions and images. In this context we proposed diagnose mental representations that students in higher education had on the subject proteins, as well as the contribution of a didactic sequence using tactile models for teaching and learning the structure and function of proteins. Thirteen students of two undergraduation courses Teacher education course in Exact Sciences (LCE) and Bachelor in Biomolecular and Physical Sciences (CFBio) - participated of this research. The tools used for data collection were: (a) an interview with the students of the courses mentioned (pre-test), (b) two courses lasting three days for each group (CFBio and LCE) and (c) an interview with the same students made one week after completion of each course (post-test). The data were of three kinds: written records (drawings and/or diagrams), one or more tactile models assembled with low cost materials, audio and pictures from the filming of the interviews. Written records and tactile models of each student were photographed and audio interviews transcribed, generating an individual document that provided a content analysis, allowing the classification of students in two categories: modellers and non-modellers, each one with its own subcategories. The detection of mental representations that students had before and after the course indicated that the contribution of the didactic sequence for the teaching/learning of the subject proteins was positive, increasing the number of students modellers and enables them (a) increase the level of complexity and sophistication in their external representations (drawings and tactile models) and (b) the development and clarification of concepts not previously understood.

The focus of this study is based on a web development team working within the confines of a Swedish authority. It has been recognized that web development teams are struggling to cooperate and work in high capacity efficiency, mostly due to the nature of the multifarious tasks at hand and their lack of understanding of each respective roles within the team. In lieu of this major downfall, establishing a mental model faceted way of thinking and working may improve effectiveness, communication and collaboration amongst all members of a functioning team. A shared mental model is developed through four stages of cognitive processes; knowing, learning, understanding and executing. The purpose of this study is to examine and show an example of how shared mental models can be developed in an existing web development team. By analyzing two workshop practices, this study aims to answer the following questions: How can workshop practices “visualizing user stories” as well as facilitating “design studio sessions” be used to establish common understanding within the web development team? How can four stages of cognitive processes (knowing, learning, understanding and executing) for developing shared mental models be understood? Participant observation and interviews are among research methods used. The ‘Shared Mental Model’ by Cannon-Bowers et al. (1993) is the primary theoretical framework used here. The results of this study indicate how workshop practices such as visualizing user stories well as conducting design studio sessions contribute to a common understanding due to increased social interaction among team members. The results also indicate that the web development team has been unable to process and exchange relevant information with each other during the initial stages of learning and development due to the lack of team building activities. This, in return affects further development of the shared mental model in the following steps. / I denna studie undersöks en svensk myndighets webbutvecklingsteam som i dag arbetar med att göra om myndighetens webbsida vilket inkluderar framtagning av nya gränssnitt och funktioner. I många fall har det visat sig att system- och webbutvecklingsteam har problem med att förhandla fram en gemensam förståelse. Dels på grund av de olika roller som ingår i ett team men även på grund av arbetsuppgifternas komplexitet och struktur. Svårigheter med att kommunicera, koordinera och samarbeta effektivt upplevs vara centralt i system- och webbutvecklingsprojekt. Att utveckla en gemensam förståelse tillika delade mentala modeller (hädanefter DMM, eng. Shared Mental Models) för lag- och uppgiftsarbetet kan förenkla kommunikation, koordination och samarbete inom ett team. Syftet med denna studie är därmed att illustrera ett exempel på hur DMM skulle kunna utvecklas inom ett webbutvecklingsteam. Webbutvecklingsteamet studeras och analyseras utifrån fyra steg av kognitiva processer (vetande, lärande, förståelse och verkställande) som demonstrerar hur DMM utvecklas steg för steg. Uppsatsen ämnar därmed att besvara följande frågor: Hur kan workshoppraktikerna ”visualisering av användarresa” och ”designstudio” bidra till etableringen av den gemensamma förståelsen inom myndighetens webbutvecklingsteam? Hur kan webbutvecklingsteamet förstås utifrån de fyra stegen av kognitiva processer; vetande, lärande, förståelse och verkställande om hur DMM utvecklas? Studien rymmer inom ramen för en fallstudie där deltagande observationer och intervjuer har nyttjats som metoder för insamling av empiriskt material. Teorin om DMM av Cannon-Bowers et al. (1993) är studiens primära teoretiska utgångspunkt. Sammanfattningsvis har studien lett fram till att de två workshoppraktikerna – visualisering av användarresa och designstudio – har bidragit till etablering av den gemensamma förståelsen i det stora hela genom social interaktion. Vidare har studiens resultat visat att webbutvecklingsteamet brister i vetandefasen eftersom teamet inte har utbyt relevant information om sig själva genom team building aktiviteter. Detta påverkar sedermera vidareutvecklingen av DMM i nästkommande steg.

The spread of influenza A subtype H5N1 has recently heightened pandemic concern and preparedness for a pandemic influenza virus has become a global priority. Research in risk communication emphasizes the importance of providing the recipients with information they need to make informed independent judgments. This entails understanding how these judgments are made, and what kind of information that serves this purpose. Decisions have been examined in a wide variety of scientific disciplines and produced several interesting methods and models to understand judgment and decisions. These methods and models were investigated and compared with regard to their fit to these conditions. The work in this thesis was oriented toward three main questions. The first question was how to find out how people would react during an emergency. The second question was what kind of research in decision theory could explain and be used to predict these results. The third question was whether a mental model of the threat of pandemic influenza can be described, and what is its implication on risk communication. A mental model approach to explore risk communications was used with qualitative interviews with health care workers in Östergötland, Sweden. The transcripts were analyzed according to methods drawn from mental models research and risk communication to extract influence diagrams. These influence diagrams serves as an abstract representation of the respondents’ mental model of the threat of pandemic influenza. This influence diagram was compared to a corresponding expert mental model developed from literature and interviews with influenza experts. The mental models approach has been shown to provide a description of comprehension with several benefits. One benefit is that the method is a relatively easy way to gather notions in the target population which can be used for drafting risk information. Another benefit is that the existing notions and sense of causal patterns can be described, instead of merely memorized facts. The comparison between the mental models of health care workers and influenza experts revealed both functional and destructive misconceptions. Unrelated information received by the respondents was also shown to be linked together in a way that is in conflict with expert knowledge. This tendency to create causal connections in order to organize knowledge may be important to consider in risk communication.

This is an educational design project exploring how prehospital care training can be altered to improve mental proficiency for emergency medical professionals.  The London Air Ambulance performs a complex life-saving procedure known as REBOA (Resuscitative Endovascular Balloon Occlusion of the Aorta) on the roadside; the only emergency medical service to do so worldwide. Teams consisting of a doctor-paramedic pairing are required to perform at their peak in extreme environments, making training for such circumstances crucial. As a result, this project strategically maps current mental processes into a framework, identifying multiple design opportunities to approach chaotic accident scenes. The framework acts as the basis for defining a curriculum, which, using Instructional Design principles, develops into a learning programme that highlights how learners experience training activities to modify communication habits and on-scene behaviour. A three-part toolkit embodies this learning programme, functioning as a sensory guide to explicitly direct attention at pre-, mid- and post-procedure interaction events between team members.

This thesis is entitled The Role of Management in the Turnaround Process and is presented for the degree of Doctor of Business Administration at the University of Manchester by Ian Roberts in April 2015. Inquiry into turnaround has largely has been carried forward in two broad areas of study: strategy and management. Strategy research has attempted to identify a single or limited number of strategies which apply in all turnaround situations, while management studies have concentrated on managers themselves or some of the techniques they employ. Neither school has systematically analysed how turnarounds are actually implemented in dysfunctional organisations and both schools are weak in extant theory. As a consequence, a holistic explanation of the process leading from crisis to viability is lacking. This thesis addresses these lacunae in three ways. Firstly, it provides a systematic study of how professional turnaround managers implement the turnaround process over time. Secondly, it applies a unique and complementary mix of extant theory which addresses both cognitive and organisational aspects of strategy formulation and implementation. Thirdly, it presents a holistic turnaround model based on six core constructs which are argued to be necessary and sufficient to explain the dynamics of the turnaround process. The thesis adopts a mixed-methods approach. A survey is used in order to gather data from turnaround professionals on implementation methods. This data is then subjected to statistical analysis in order to identify the most important factors for implementation. These concepts are then blended into a conceptual framework which is tested for its explanatory and predictive power on a matched pair of turnaround case studies of two mid-sized UK manufacturing companies in the household goods sector, one of which executed a successful turnaround and one of which failed in the attempt. The model is able to explain and predict the outcome in both cases. The thesis is one of only a handful of turnaround studies which employs a rigorous case study research protocol. Its principal contribution is that of a middle range turnaround theory of the causal factors leading from organisational crisis to dissolution or viability.

Personality has long been linked to performance. Evolutions in this relationship have brought forward new questions regarding the true nature of how personality impacts performance. Both direct and indirect relationships have been proven significant. This study further investigated potential indirect relationships by including a mediating variable, mental model formation, in the personality-performance relationship. Undergraduate students were assessed in a 6-week period, Time 1 - Time 2 experiment. Conceptualizations of personality included measures of the Big 5 model and Self-efficacy, with performance measured by content quiz and overall course scores. Findings showed that the Big 5 personality traits, extraversion and agreeableness, positively and significantly impacted commonality with the instructor’s mental model. However, commonality with the instructor’s mental model did not impact performance. In comparison, commonality with an expert mental model positively and significantly impacted performance for both the content quiz and overall course score. Furthermore, similarity with an expert mental model positively and significantly impacted overall course performance. Hypothesized full mediation of mental model formation for the personality-performance relationship was not supported due to a lack of direct effect relationships required for mediation. However, a revised conceptualization of results emerged. Findings from the current study point to the novel and unique role mental models play in the personality-performance relationship. While personality traits do impact mental model formation, accuracy in the mental models formed is critical to performance.

Despite disaster managers’ best efforts, inter-organizational disaster management suffers from varying levels of success. One factor that is likely to account for these variations is team mutual understanding, also known as common ground. To validate the potential effect of common ground in disaster management, the thesis investigates common ground in several interviews with disaster managers and in an experimental study involving an inter-organizational disaster event scenario. Analysis of interviews revealed that disaster managers perceived gaps in understanding between responders, the importance of mutual understanding, and perceived common ground similarly to depictions in theory with a few exceptions. Analyses of the experimental study indicated that contextual factors of Team composition, Problem solving approach and Type of tasks differently impacted measures of performance and implicit coordination, and that implicit coordination partially mediated and supressed the relationship between contextual factors and decision quality. Findings suggest the variation in disaster managers’ performance can be ascribed to common ground, implicit coordination, and contextual factors. Moreover, results showed the satisfaction with outcome did not correlate with expert rated quality of decision; and that while satisfaction related to consensus and quality of the decision was linked to generating alternative ideas and debate. Collaboration proved to be more effective in public communication tasks, especially for homogenous team composition. The findings support initiatives for more cross-training and further lab and field experiments.

abstract: ABSTRACT The cold and the flu are two of the most prevalent diseases in the world. Many over the counter (OTC) medications have been created to combat the symptoms of these illnesses. Some medications take a holistic approach by claiming to alleviate a wide range of symptoms, while others target a specific symptom. As these medications become more ubiquitous within the United State of America (USA), consumers form associations and mental models about the cold/flu field. The goal of Study 1 was to build a Pathfinder network based on the associations consumers make between cold/flu symptoms and medications. 100 participants, 18 years or older, fluent in English, and residing in the USA, completed a survey about the relatedness of cold/flu symptoms to OTC medications. They rated the relatedness on a scale of 1 (highly unrelated) to 7 (highly related) and those rankings were used to build a Pathfinder network that represented the average of those associations. Study 2 was conducted to validate the Pathfinder network. A different set of 90 participants with the same restrictions as those in Study 1 completed a matching associations test. They were prompted to match symptoms and medications they associated closely with each other. Results showered a significant negative correlation between the geodetic distance (the number of links between objects in the Pathfinder network) separating symptoms and medications and frequency of pairing symptoms with medication. This provides evidence of the validity of the Pathfinder network. It was also seen that, higher the relatedness rating between symptoms and medications in Study 1, higher the frequency of pairing symptom to medication in Study 2, and the more directly linked those symptoms and medications were in the Pathfinder network. This network can inform pharmaceutical companies about which symptoms they most closely associate with, who their competitors are, what symptoms they can dominate, and how to market their medications more effectively. / Dissertation/Thesis / Masters Thesis Engineering 2020
