Only a small percentage of people with mental health issues utilize mental health services. This would seem contradictory given the increasing understanding of mental disorders, their high prevalence, and associated disability and distress. Research shows that individual level factors, such as perceptions of need, mental health knowledge, mental health attitudes, and mental health literacy, are related to individuals’ decisions to seek mental health services. The Health Belief Model (HBM) posits four types of health beliefs that affect an individual’s health behavior, in this case, the decision to seek mental health services. To date, researchers and clinicians have no assessment tool to empirically identify the factors affecting a particular individual’s decision making about using mental health services. Therefore, the goal of this study was to develop and validate a self-report instrument, called the Mental Health Belief Model Assessment (MHBMA), designed to assess readiness to seek formal mental health services. Based on the HBM, the MHBMA includes 76 items grouped into five scales: Perceived Susceptibility and Fears, Perceived Severity, Perceived Benefits, Perceived Barriers, and Self-efficacy. A 20-item short form was also developed. The responses of a validation sample of 192 adults provided the initial evidence for reliability and validity of the MHBMA. In terms of reliability, internal consistency reliability was high for each scale, with Cronbach’s alphas ranging from .90 to .97, and test-retest correlation coefficients for each scale were strong, ranging from .82 to .92. Evidence for validity was examined via test content, internal structure, and relations to other variables. Specifically, moderate to high correlations in the expected directions were found between the MHBMA and Attitudes Toward Seeking Professional Psychological Help Scale-Short Form and the Barriers to Help Seeking Scale. The scale scores on the MHBMA were also examined in relation to a number of demographic and service use variables. Guidelines for use and interpretation on the MHBMA, delimitations and limitations of the current study, and implications for research and practice are discussed.

Background. In England and the UK there has been a move to provide the consumer with more choice in over the counter medicine. In recognition of the number of drugs now available without prescription, new models and frameworks are being utilised with the aim to educate the public about self-treatment. How health information is sought has also undergone transformation with the advent of the internet, the adoption and utilisation of this resource has had a significant impact on how the healthcare consumer seeks information. Aims and Methods. The aim of this study was to investigate the provision of and access to consumer health information in England, specifically with reference to over the counter medicines to promote understanding of the consumers attitudes and opinions to this type of medicine and their health information seeking behaviours. The findings of the study were used to provide recommendations to the stakeholders involved; healthcare organisations, healthcare professionals and the healthcare consumer. The research consisted of a survey (n=324) and was analysed using quantitative and qualitative methods. Results. The majority of respondents utilised over the counter medicine responsibly and with few adverse events. The General Practitioner is the main source of information and online sources the next most utilised resource. Effectiveness and following advice/recommendations were amongst the themes identified that made a treatment episode with over the counter medicines successful. Unsuccessful treatment episodes included those with escalation of symptoms. Factors governing successful health information seeking were problem solving through self diagnosis and expanding knowledge on an existing health issue. Conclusions. Over the counter medicines are a widely used commodity but respondents continue to have a heavy reliance on the general practitioner for prescription medicines, especially for minor ailments. Evidence exists that individuals utilise information seeking behaviour for self treatment and the use of over the counter medicines. However, adoption of self care models need to be increased through educating health care consumers to maximise the potential benefits of these frameworks for the stakeholders.

No Brasil, o ponto de vista de que a competição tributária (sempre retratada como "guerra fiscal") é algo conflituoso faz com que seja difundida uma visão negativa sobre um fenômeno que nem sempre é visto como tal na literatura econômica internacional. Muitos economistas veem essa competição como algo que, sendo capaz de coibir o comportamento rent-seeking por parte dos governantes, seria benéfico para a sociedade. Com base nessa ideia, usando o modelo de Eggert e Sorensen (2008), foi testado se variáveis proxy relativas à intensidade da competição tributária e ao comportamento rent-seeking de políticos no poder eram correlacionadas. Usou-se dados dos 26 estados brasileiros e do Distrito Federal para os anos de 2001 a 2009. Os resultados mostraram que, embora essas variáveis proxy não fossem correlacionadas para os níveis de escolaridade mais baixos, no nível mais alto, havia correlação entre essas duas variáveis, embora ela fosse positiva, o que rejeitava a hipótese de que uma maior competição tributária seria capaz de diminuir o comportamento rent-seeking dos políticos. / In Brazil, the point of view that tax competition (commonly referred to as a “fiscal war”) is something conflictive spreads a negative perspective on a phenomenon that is not always seen as such in the international economic literature. Many economists see this competition as something that, in being able to reduce rent-seeking behavior by politicians, would be beneficial to society. Stemming from this idea, and using the model from Eggert and Sorensen (2008), it was tested if proxy variables relating to the intensity of tax competition and to the rent-seeking behavior of politicians in office were correlated. Data from all the 26 Brazilian states and also Distrito Federal, from 2001 to 2009, were used. The results showed that, although the proxy variables were not correlated for the less skilled groups of workers considered, at the high skilled group, there was correlation between the two variables, but it was positive, which rejected the hypothesis that a more intense tax competition would be able to repress rent-seeking behavior by politicians.

Introdução: Estima-se que os comportamentos de risco no trânsito, como erros e violações, sejam responsáveis por aproximadamente 90% dos acidentes automobilísticos. Dentre as principais variáveis preditoras de comportamento de risco no trânsito estão os traços de personalidade do condutor. A associação positiva entre impulsividade, busca de sensações e comportamentos de risco no trânsito já é bem documentada na literatura. No entanto, estudos que explorem essas associações entre condutores infratores versus não infratores são escassos, principalmente no Brasil. Objetivo: Explorar as associações entre impulsividade, busca de sensações e comportamentos de risco no trânsito em uma amostra de condutores infratores versus não infratores da cidade de Porto Alegre. Método: A amostra foi composta por 158 condutores infratores que tiveram o direito de dirigir suspenso nos últimos 12 meses por acúmulo de pontos (68,4%) ou tipo de infração específica (31,6%), selecionados no Departamento Estadual de Trânsito do Rio Grande do Sul (79,7% homens) e 181 não infratores (76,2% homens) captados em três Centros de Formação de Condutores e em dois parques públicos locais. As medidas utilizadas foram: a Escala de Impulsividade de Barrat (BIS-11), o Inventário de Busca de Sensações de Arnett (AISS) e um questionário padronizado para coleta de informações demográficas e de comportamentos de risco no trânsito. As variáveis foram analisadas através de regressão logística de acordo com um modelo hierarquizado. O nível de significância adotado foi 5%. Resultados: Maior impulsividade (OR = 4,8, IC 95%: 2,68-8,6), anos de estudo (OR=0,91, IC 95%: 0,85-0,97); dirigir com maior frequência (OR = 4,01, IC 95%: 2,05-7,83), assumir infrações de outro condutor (OR = 2,91, IC 95%: 1,63-5,19), solicitar que outro condutor assumisse suas infrações (OR = 6,74, IC 95%: 2,39-19,25), envolvimento em acidentes de trânsito com vítima (OR = 2,73, IC 95%: 1,24-6,01) e consumir bebida alcoólica nos últimos 12 meses (beber não binge = OR 0,77, IC 95%: 0,38-1,55; binge drinking = OR 1,97, IC 95%: 0,87-4,47) foram significativa e independentemente associados à suspensão do direito de dirigir. Não foi constatada associação entre busca de sensações e ter o direito de dirigir suspenso. Conclusão: Os achados sugerem que a impulsividade, alguns comportamentos associados a risco – tais como envolvimento em acidentes graves, beber bebida alcoólica nos últimos 12 meses, assumir infrações de outro condutor, solicitar que outro condutor assumisse suas infrações - e a frequência com que o condutor dirige foram preditores para o cometimento de mais infrações; também se evidenciou que possuir mais anos de estudo representou um fator de proteção à direção segura. Nesse sentido, nossos resultados demonstram a natureza complexa e multideterminada do fenômeno. Espera-se que este trabalho, pioneiro no Brasil, contribua para a identificação de potenciais fatores de risco e associados ao cometimento de infrações, bem como contribua na discussão de medidas de avaliação, reabilitação e fiscalização para o trânsito. / Introduction: It is estimated that risk behaviors in traffic, such as errors and violations, are responsible for approximately 90% of all automobile accidents. Among the leading predictors of risk behavior in traffic are driver personality traits. The positive association between impulsivity, sensation seeking and risk behaviors in traffic is already well documented in literature. However, studies that explore these associations among offender drivers and non-offender drivers are scarce, especially in Brazil. Objective: To explore the association between impulsivity, sensation seeking and risk behavior in traffic in a sample of offender drivers versus non-offender drivers in the city of Porto Alegre. Method: The sample comprised 158 offender drivers whose right to drive had been suspended over the past 12 months due to an accumulation of points (68.4%) or a specific violation (31.6%), selected at the Rio Grande do Sul State Traffic Department (79.7% men) and 181 non-offender drivers (76.2% men) from three Driving Schools and in two local parks. Measures used were: the Barrat Impulsiveness Scale (BIS-11), the Arnett Inventory of Sensation Seeking (AISS) and a standardized questionnaire for the collection of information of demographics and risk behavior in traffic. The variables were analyzed through logistic regression according to a hierarchical model. The adopted level of significance was 5%. Results: More impulsiveness (OR = 4.8, IC 95%: 2.68-8.6), years in school (OR=0.91, IC 95%: 0.85-0.97); frequent driving (OR = 4.01, IC 95%: 2.05-7.83), take on other driver’s violations (OR = 2.91, IC 95%: 1.63-5.19), request that other driver’s take on one’s violations (OR = 6.74, IC 95%: 2.39-19.25), involvement in traffic accidents with a victim (OR = 2.73, IC 95%: 1.24-6.01) and drinking alcoholic beverages during the last 12 months (non-binge drinking = OR 0.77, IC 95%: 0.38-1.55; binge drinking = OR 1.97, IC 95%: 0.87-4.47) were significantly and independently associated with the suspension of driving privileges. We verified no association between sensation seeking and the suspension of driving privileges. Conclusion: The findings suggest that impulsivity and behaviors associated with risk – such as involvement in serious accidents, drinking alcoholic beverages within the last 12 months, taking on violations of other drivers, requesting that other drivers take on his/her violations - and the frequency of driving were indicative of committing additional violations; it was also shown that more years of study represented a factor favoring safe driving. In this sense, our results show the complex and multidetermined nature of the phenomenon. It is hoped that this pioneering study in Brazil contributes to the identification of potential risk factors and those associated with committing violations, as well as contributing to the discussion of measures for evaluation, rehabilitation and monitoring of traffic.

Les vidéos sont de plus en plus utilisées dans un contexte pédagogique, mais les formats de présentation sur les plateformes spécialisées (e.g., MOOC) sont variés et peu analysés. Il paraît cependant nécessaire de s’intéresser aux processus à l’oeuvre lors des tâches d’apprentissage et de recherche d’information (RI) pour adapter au mieux les environnements vidéo aux besoins et ressources cognitifs des individus. Au cours de ces deux tâches (RI et apprentissage), la littérature scientifique fait apparaître l’importance de la qualité du modèle mental de l’individu. Pour favoriser la construction d’un modèle mental pertinent par l’individu, deux types d’étayage sont envisagés au cours de cette thèse : la segmentation de la barre de navigation et la structuration du contenu de la vidéo par une table des matières. Les trois premières études ont permis de montrer que la présence conjointe des deux niveaux d’étayage a favorisé la performance en RI (étude 1), mais qu’elle n’a pas permis la construction d’un modèle mental efficace du contenu de la vidéo (étude 2). Au cours de l’étude 3, différents formats de présentation ont été comparés : le format pop-up a permis de diminuer la difficulté perçue de la tâche de RI. Les deux dernières études se sont centrées sur les effets de l’étayage lors d’une tâche d’apprentissage. La présence d’étayage n’a pas amélioré la qualité de l’apprentissage (étude 4). Néanmoins, lorsque l’apprenant est rendu actif, grâce à une tâche de RI par exemple, la mémorisation du contenu de la vidéo a été améliorée (étude 5). Les résultats sont discutés en termes de rôle organisateur de l’étayage permettant une récupération efficace de l’information. L’étayage organiserait l’information entrante dans l’environnement vidéo ou la mémoire de l’individu selon la tâche. / Videos are more and more used in pedagogical contexts, but presentation formats on specific platforms (e.g., MOOC) are varied and not so much analyzed. However, it seems necessary to focus on processes involved during learning and information seeking (IS) tasks to adapt video-based environments to individuals’ needs and cognitive resources. During learning and IS, scientific literature highlights the importance of individuals’ mental models. To encourage the construction of a relevant mental model, two types of scaffolding are considered in this thesis: the segmentation of the timeline and the structuration of the video content using a table of contents. The first three studies showed that the conjoint use of the two levels of scaffolding enhanced IS performance (study 1), but it did not promote the construction of a relevant mental model of the video content (study 2). During study 3, several presentation format were compared: the pop-up format reduced perceived difficulty of the IS task. The last two studies focused on the effects of scaffolding during a learning task. The presence of scaffolding did not enhanced learning performance (study 4). Nevertheless, when the learner was made active, thanks to an IS task for example, memorization of the video content was improved (study 5). Results are discussed in terms of organizing role of scaffolding enabling effective recovery of information. Scaffolding is here thought to organize incoming information in the video-based environment or in individual’s memory according to the task.

An increasing proportion of people in the United Kingdom are living longer with long-term conditions. The National Health Service is facing the challenge of increased pressure on its service provision. A number of key health policy initiatives encourage individuals to make informed choices and purport to give them rights and control over their own health and healthcare. Within this context, people are actively encouraged to self-care, manage diseases, and make decisions and choices about healthcare in an informed way. To facilitate this, it is important to gain an understanding of the health information seeking behaviours of older people. Health information is available from various sources but little is known about the health information seeking behaviours of older people and what affects this. By exploring this, it helps to reveal how health information is sought regarding on-going health conditions and provides greater depth in understanding the health information seeking process. The study explores older people's experiences and views on their health information seeking behaviours and endeavours to gain a better understanding of these experiences and views. The study draws on constructivist grounded theory with two phases to data collection: Nine participants completed un-structured diaries over two months with follow up semi-structured interviews, a further twenty participants participated in semi-structured interviews. Major categories were inductively drawn from participant's responses. Strategies of health information seeking behaviours are not necessarily fixed, but subject to change over time. The analysis suggested three main categories that explained the health information seeking behaviours of older people. Three interrelated conceptual categories were identified: (1) Regulating self (2) Self managing and (3) Self-mobilisation. These categories formed the basis of the emergent substantive theory called 'navigating later life'. There were different patterns of behaviours between participants which captured variations in information seeking; these informed the development of a typology of health information seekers. Ageing in the 21st century is a complex process; with older people inhabiting a world of more choice, multiple sources of knowledge, changed healthcare roles and increased self-care undertaken within the home. The study provides important insights for healthcare professionals and raises implications for strategies aimed at improving older people's access to appropriate health information. The navigation model provides a potentially valuable tool for policy makers when considering the support older people require to self-care.

The research presented in this thesis develops an improved design methodology for designing complex systems. While traditional methods have been able to create complex systems, their success is usually overshadowed by long delays and expensive overruns. The method developed within this research is known as Value Seeking System Design (VSSD) and builds upon the foundations of the System Engineering (SE) and Value Driven Design (VDD) approaches. Creation and implementation of the new design environment is provided, including a method on how to create the value model for any complex system. Key conclusions from this work include a need to redefine the process in which stakeholder needs are currently defined and captured as well as a need to create an improved value model. Defining all stakeholders’ needs as requirements constrains the designer to a rigid solution space, which may not include the “best” solution for the stakeholder. Similarly not including the social aspects within a value model causes the designer to make poor value trades. To overcome these problems the VSSD technique incorporates desirements and their associated design desirability functions within the design process to create a non-rigid solution space while the value model has been redeveloped to easily incorporate the performance, economic and social aspects of a design, to allow a more accurate and balanced value trade off analysis to occur. Benchmarking the VSSD approach against the current state of the art methods (SE and VDD) highlighted the advantages of adapting a value approach to complex system design compared to traditional requirement based techniques. Additionally while all three approaches were capable of designing complex systems the VSSD approach was demonstrated to be an improved design methodology as it possessed the benefits inherent within both the SE and VDD approaches without suffering from their limitations.

abstract: Many medical students are reluctant to seek help during the course of their four years of medical school. When they do finally ask for help, some are already burned out or in a crisis. One of the main reasons students are apprehensive about seeking help is stigma. This mixed methods action research study was conducted to explore whether a help-seeking, anti-stigma campaign improved help-seeking behaviors. The innovation was an anti-stigma campaign consisting of three components: (a) video vignettes of upper class students normalizing help-seeking, (b) a Friends and Family of Medical Students session to educate those closest to the student about medical school, and (c) an anonymous, online mental health screening tool. Data from the General Help-Seeking Questionnaire, individual interviews, and institutional data from the medical school provided information about the effects of the campaign and determined factors influencing help-seeking. Using these strategies, I hoped to normalize help-seeking and break down the barriers of stigma. Major findings included: Students were more likely to seek help from personal resources (close family and friends); Students may be more proactive with personal resources, but need prompting for college or formal resources; Students’ beliefs and attitudes were influenced by those closest to them and; First year students were more likely to seek help than their second year classmates. In addition, data inspired future research ideas and programming regarding the topic of help-seeking in medical school. / Dissertation/Thesis / Doctoral Dissertation Leadership and Innovation 2016

abstract: Adolescent substance use carries a considerable public health burden, and early initiation into use is especially problematic. Research has shown that sensation seeking traits increase risk for substance use experimentation, but less is known about individual and contextual factors that can potentially protect against this risk. This study utilized a longitudinal sub sample of youth (N=567) from a larger study of familial alcoholism to examine sensation seeking in early adolescence (ages 10-15) and its relations to later substance use experimentation. Hypotheses tested whether individual executive control, parenting consistency, neighborhood disadvantage, and neighborhood ethnic concentration moderated sensation seeking’s effects on substance use experimentation using multilevel zero-inflated Poisson modeling. Across models, higher levels of sensation seeking were predictive of a higher likelihood of having initiated substance use, but sensation seeking was not significantly related to the number of different substance use classes tried. Only neighborhood disadvantage emerged as a significant moderator of the path from sensation seeking to substance use initiation. The strength of sensation seeking effects on substance use initiation increased as neighborhood disadvantage decreased below average levels, with the most advantaged neighborhoods exhibiting the strongest link between sensation seeking and substance use. There was also a trend towards the most disadvantaged neighborhoods exhibiting increased sensation seeking effects on substance use initiation. These results highlight the importance of focusing on relatively more advantaged areas as potentially risky environments for the externalizing pathway to substance use. / Dissertation/Thesis / Doctoral Dissertation Psychology 2016

abstract: Online social media is popular due to its real-time nature, extensive connectivity and a large user base. This motivates users to employ social media for seeking information by reaching out to their large number of social connections. Information seeking can manifest in the form of requests for personal and time-critical information or gathering perspectives on important issues. Social media platforms are not designed for resource seeking and experience large volumes of messages, leading to requests not being fulfilled satisfactorily. Designing frameworks to facilitate efficient information seeking in social media will help users to obtain appropriate assistance for their needs and help platforms to increase user satisfaction. Several challenges exist in the way of facilitating information seeking in social media. First, the characteristics affecting the user’s response time for a question are not known, making it hard to identify prompt responders. Second, the social context in which the user has asked the question has to be determined to find personalized responders. Third, users employ rhetorical requests, which are statements having the syntax of questions, and systems assisting information seeking might be hindered from focusing on genuine questions. Fouth, social media advocates of political campaigns employ nuanced strategies to prevent users from obtaining balanced perspectives on issues of public importance. Sociological and linguistic studies on user behavior while making or responding to information seeking requests provides concepts drawing from which we can address these challenges. We propose methods to estimate the response time of the user for a given question to identify prompt responders. We compute the question specific social context an asker shares with his social connections to identify personalized responders. We draw from theories of political mobilization to model the behaviors arising from the strategies of people trying to skew perspectives. We identify rhetorical questions by modeling user motivations to post them. / Dissertation/Thesis / Doctoral Dissertation Electrical Engineering 2017
