Work wellness in a financial services institution : a longitudinal study / Mark Orpen-Lyall

Orpen-Lyall, Mark Raymond January 2008 (has links)
Most employers agree that the effectiveness and success of their organisations depend on the effective utilisation of their human resources. Ill health in the workplace is a threat to optimal productivity, reduced absenteeism, provision of sustainable employee benefits, a motivated workforce, staff retention and maximisation of profits. Burnout and engagement are therefore important fields of investigation in the industrial psychology field. The aim of this study was to: test a model of work-related well-being; develop and evaluate a resilience intervention programme for a large financial services institution in South Africa. Article 1 used a cross-sectional survey design. The participants were predominantly in the administrative, call centre and IT divisions (N = 192). Article 2 was the development of a resilience model, which was based on the integration of thinking from an extensive literature review by the researcher. Article 3 used an experimental design, with a control group (n=51) and an experimental group («=55). Information was collected in a longitudinal research. The research method for each of the three articles of this study consisted of a brief literature review and an empirical study. The measuring instruments used in this study were the Maslach Burnout Inventory - General Survey (MBI-GS), Utrecht Work Engagement Scale (UWES), Job Demands-Resources Scale (JD-RS), Health subscales, Organisational Commitment subscales, the ASSET questionnaire, the Life Orientation Test - Revised (LOT-R) and a biographical questionnaire. In both article 1 and article 3, descriptive statistics were computed to describe the data; as were Pearson product-moment correlation coefficients to specify the relationship between the variables. In article 1, multiple regression analyses were conducted to determine the proportion of variance in the dependent variable that is predicted by the independent variables. In article 3, paired-samples f-tests were used to determine the difference in results for year 1 and year 2. Article 1 showed the central role that low optimism plays in contributing to burnout, and high optimism plays in work engagement. Interestingly, high social support was linked to increased cynicism, whilst low social support contributed to dedication. Burnout contributed to both physical and psychological ill health. Dedication and low cynicism contributed to affective commitment, whilst engagement and low cynicism contributed to behavioural commitment. Article 2 was the development of a multidimensional, proactive coping approach which consistently strives to develop and enhance the individual's resilience coping reservoir pools (mental, spiritual, socio-emotional and physical) leading to improved resilience, wellness and quality of life. Each reservoir pool has activities that enhance the fitness of the individual, namely physical (rest and relaxation, exercise and nutrition), mental (stimuli, reflection and empowering thinking), spiritual (coat of arms, pay it forward and gratitude), socio-emotional (breaking destructive relationships and nurturing relationships, responsibility). Article 3's results showed that the resilience intervention resulted in a statistically significant difference decrease in psychological ill health. Recommendations for future research were made. / Thesis (Ph.D. (Industrial Psychology))--North-West University, Potchefstroom Campus, 2009.

Exploring the sense of belonging of Setswana–speaking older women in Ikageng who were forcibly relocated during apartheid / Kolobe P.C.

Kolobe, Patricia Stockie January 2011 (has links)
The social displacement enforced by the South African Group Areas Act between 1954 and 1955 was understandably experienced as a destructive process with physical and emotional consequences arising from various types of losses, separation and feelings of helplessness. Although the forced removals affected all the people in the community - also in later years and generations, it seems as if older people are affected the more as they still remember the losses they experienced when they were removed from their homes and their communities, when their heritage and their culture were displaced. The sense of belonging being experienced by older people, who were subjected to these forceful removals, is therefore unclear. In this study the sense of belonging is defined as the effective participation, involvement, contribution and emersion of people when relating to their social, physical, spiritual, emotional and cultural places. In this study older (aged 60 and above) Setswana speaking residents of Ikageng, a community just outside Potchefstroom in the North West Province, South Africa, who were also forcibly relocated from Kloppersville to Ikageng, 10 kilometers away from Kloppersville, were asked to identify places that are important to them in Ikageng and to describe the meanings they attach to these places. In the research, no one identified any places of importance in Ikageng, instead throughout the research they kept on referring to their lives in Kloppersville, their former place of residence, the place where they were forcibly removed from – giving purpose and direction to this study and leading to the question: What are the experiences related to the sense of belonging of Setswana speaking older women who were forcibly relocated during Apartheid in South Africa? The older persons’ experiences of their sense of belonging in the place where they were forcibly relocated to must be understood in relation to the past. A qualitative research approach was used and a narrative research design followed. Two sets of data were gathered and are reported on in this article that focuses on the narrations of 11 older Tswana people from the Day Care Centre for the Aged in Ikageng. Narrative data collection and analysis, as well as a variety of qualitative research methods and media, were used to collect data. These include: focus group discussions, the Mmogo– MethodTM, videos, audio, photographs and observational notes. The thematic analysis of textual data, narrative–oriented inquiry as well as visual data, established trustworthiness of this research through crystallization. By drawing on the deeper symbolic meaning derived through the use of the MmogomethodTM, the study has revealed that the sense of belonging is a relational phenomenon that cannot be understood in absence of the different relational environments. In an African culture the relationship with the current environment resonates with the effects that historical processes, structural abuses, discrimination, racism and devaluation had on individuals whose lives have been uprooted. This study has shown that the older women have a micro–organic relational sense of belonging to the place of relocation and not to the whole context and other relational environments and that they revealed more sense of belonging towards the place where they were relocated from. / Thesis (M.A. (Research Psychology))--North-West University, Potchefstroom Campus, 2012.

Barriers to the acceptance of road safety programmes among rural road users : developing a brief intervention

Sticher, Gayle January 2009 (has links)
Motorised countries have more fatal road crashes in rural areas than in urban areas. In Australia, over two thirds of the population live in urban areas, yet approximately 55 percent of the road fatalities occur in rural areas (ABS, 2006; Tziotis, Mabbot, Edmonston, Sheehan & Dwyer, 2005). Road and environmental factors increase the challenges of rural driving, but do not fully account for the disparity. Rural drivers are less compliant with recommendations regarding the “fatal four” behaviours of speeding, drink driving, seatbelt non-use and fatigue, and the reasons for their lower apparent receptivity for road safety messages are not well understood. Countermeasures targeting driver behaviour that have been effective in reducing road crashes in urban areas have been less successful in rural areas (FORS, 1995). However, potential barriers to receptivity for road safety information among rural road users have not been systematically investigated. This thesis aims to develop a road safety countermeasure that addresses three areas that potentially affect receptivity to rural road safety information. The first is psychological barriers of road users’ attitudes, including risk evaluation, optimism bias, locus of control and readiness to change. A second area is the timing and method of intervention delivery, which includes the production of a brief intervention and the feasibility of delivering it at a “teachable moment”. The third area under investigation is the content of the brief intervention. This study describes the process of developing an intervention that includes content to address road safety attitudes and improve safety behaviours of rural road users regarding the “fatal four”. The research commences with a review of the literature on rural road crashes, brief interventions, intervention design and implementation, and potential psychological barriers to receptivity. This literature provides a rationale for the development of a brief intervention for rural road safety with a focus on driver attitudes and behaviour. The research is then divided into four studies. The primary aim of Study One and Study Two is to investigate the receptivity of rural drivers to road safety interventions, with a view to identifying barriers to the efficacy of these strategies.

Dispositional optimism and attentional bias to happy facial expressions

Klarén, Anton January 2018 (has links)
Research suggests that the human attentional system is biased towards emotional events in the environment. This attentional bias is believed to be an adaptive function that can provide survival benefits for the organisms that possess it. Dispositional optimism is a trait defined as a general expectation that good things will happen in the future. This trait has received interest as an adaptive trait that has a multitude of psychological and physical benefits for the individuals who exhibit it. The aim of this study is to examine whether there is a difference in the attentional bias towards happy and angry facial expressions based on level of dispositional optimism using the dot-probe paradigm. Thirty-two psychologically and neurologically healthy females (mean age = 26.5, SD = 5.8) participated in the study. They completed a questionnaire measuring dispositional optimism and performed the dot-probe task in a laboratory setting in the University of Skövde. In the dot- probe task a short exposure (100 ms) of photographs depicting happy, angry and neutral facial expressions was used as emotional cues. A general bias towards happy faces across all participants was detected. Also, a clear trend towards an interaction between DO and AB to emotional faces was found in the group high in DO displaying and AB towards happy facial expressions. This study implies that for the psychologically and neurologically healthy population, a fast operating and automatic AB for positive stimuli exists, moreover, this AB may be modulated by individual differences in DO.

Odolnost vůči psychické zátěži u cyklistů s handicapem v kontextu užívání návykových látek / Resistibility Against Psychological Stress of Cyclists with Disabilities in Context with Usage of Addictive Substances

NOSKOVÁ, Alena January 2012 (has links)
The thesis deals with a resistance to a psychological stress at cyclists with disabilities in context of addictive substances use. The theoretical part of the thesis summarizes findings concerning handicapped people cycling, personal characteristics of sportsmen, and also an influence of a sports performance by used substances together with an institutional framework of this issue. In the theoretical part there are described various views of the resistance to the psychological stress with an emphasis on an arousability, dispositional optimism and Sense of Coherence. A score of these three indicators was determined at respondents within an empirical part of the thesis. The aim of the thesis was to define a level of a psychological resistance at cyclists with disabilities and its relation to the addictive substances use. Partial aims of the thesis were focused on respondents´ awareness of effects of addictive substances on the sports performance, particular substances used by respondents, an openness to the addictive substances use to influence the sports performance and views of such a use in the sports environment. Scales of the arousability, Optimism Scale and Sense of Coherence, detecting levels of the arousability, dispositional optimism and Sense of Coherence, were applied in the research investigation. The research sample consisted of men ? cyclists with physical or sense handicaps, participating in cycle racing disciplines in the Czech Republic. Three hypotheses were tested in this investigation. The empirical part of the thesis has led to conclusions concerning a level of the psychological resistance at cyclists with disabilities from aspects of the Sense of Coherence, arousability and dispositional optimism. A frequency of the addictive substances use to influence the sports performance was in accordance with a predetermined hypothesis, the research sample of cyclists with disabilities showed a lower use of addictive substances to influence the sports performance compared to the cyclists without disabilities. Similarly, the openness to the addictive substances use was lower at the research sample.

Decisões de financiamento e de investimento das empresas sob a ótica de gestores otimistas e excessivamente confiantes / Financing and investment decisions of firms by overconfident and optimistic managers

Lucas Ayres Barreira de Campos Barros 19 December 2005 (has links)
Esta pesquisa investiga empiricamente as possíveis influências de gestores cognitivamente enviesados sobre as decisões de financiamento e de investimento das empresas. Especificamente, dois vieses cognitivos amplamente documentados na literatura comportamental e psicológica são enfocados: o otimismo e o excesso de confiança. As hipóteses de pesquisa são derivadas de um crescente corpo de teorias dedicadas à exploração das implicações para a empresa da presença destes traços psicológicos nos seus gestores. Embora o otimismo e o excesso de confiança tendam a se manifestar conjuntamente, é possível tratá-los separadamente para fins analíticos. Genericamente, o otimismo costuma ser modelado como uma superestimação da probabilidade de ocorrência de eventos favoráveis, ao passo que o excesso de confiança reflete-se na subestimação da volatilidade ou do ruído de processos que envolvem incerteza. Argumenta-se que uma predição central emerge do conjunto dos modelos considerados, qual seja, empresas geridas por indivíduos otimistas e/ou excessivamente confiantes são mais propensas ao endividamento, ceteris paribus. Alguns modelos que enfocam apenas o viés do otimismo também sugerem que estas empresas são mais propensas a adotar uma hierarquização de preferências por fontes de financiamento conhecida como pecking order. Quanto ao impacto destes vieses sobre o valor de mercado e sobre as decisões de investimento das empresas os resultados teóricos são ambíguos. O estudo oferece duas contribuições principais. A primeira é o teste pioneiro das predições referidas acima e a segunda é a proposição de uma estratégia inovadora de identificação destes vieses entre os gestores. Especificamente, sólidas evidências empíricas apoiadas por argumentos teóricos diversos sugerem que os indivíduos que gerenciam o seu próprio negócio (empreendedores) são particularmente propensos a exibir excesso de confiança e otimismo exacerbado em seus julgamentos. Alternativamente, estes vieses são identificados com base no padrão de posse de ações da própria empresa por parte dos seus gestores. Utiliza-se uma amostra de 153 empresas brasileiras observadas entre os anos de 1998 e 2003. Diferentes métodos foram empregados para estimar os parâmetros dos modelos empíricos, com destaque para o procedimento baseado no Método dos Momentos Generalizado conhecido como GMM Sistêmico, sempre com o objetivo de controlar os problemas de endogeneidade relacionados, em particular, com variáveis omitidas, erros de mensuração e com a provável determinação simultânea de algumas variáveis. Os dados não mostram evidências favoráveis à hipótese da hierarquização de fontes de financiamento. Tampouco é possível divisar qualquer impacto sistemático das variáveis substitutas do otimismo/excesso de confiança dos gestores sobre medidas do valor de mercado e do volume geral de investimentos das empresas. Um resultado bastante significativo emerge, não obstante, da análise empírica: empresas geridas por indivíduos classificados como otimistas/excessivamente confiantes revelam-se, depois de isolados diversos fatores intervenientes, substancialmente mais alavancadas financeiramente do que as demais. Esta evidência, compatível com a predição central do conjunto de teorias comportamentais consideradas, é robusta a variações do método de estimação, da especificação do modelo empírico e da definição operacional escolhida para os vieses de interesse. A significância econômica aliada à significância estatística da influência observada sugere que otimismo e o excesso de confiança dos gestores podem exercer impacto significativo sobre decisões corporativas e, em especial, podem ser importantes determinantes da estrutura de capital das empresas. / This research empirically investigates the possible impacts of cognitively biased managers on firms\' financing and investment decisions. Specifically, two cognitive biases that are widely recorded in the behavioral and psychological literature are considered: optimism and overconfidence. The testable hypotheses are derived from a growing body of theories that focus on the implications of biased managers for firms. Although optimism and overconfidence tend to appear together, it is possible to treat them separately for analytical purposes. Generically, optimism is usually modeled as an overstatement of the probability of occurrence of favorable events and overconfidence is reflected in the understatement of the volatility or of the noise of processes that involve uncertainty. It is argued that one central prediction emerges from the set of models considered, namely, that companies managed by optimistic and/or overconfident individuals are more inclined towards debt financing, ceteris paribus. Some models that focus on the bias of optimism alone suggest, in addition, that these companies are more prone to establishing an ordering of preferences for alternative sources of financing known as pecking order. When it comes to the impact of these biases on the firm\'s market value and on its investment decisions the theoretical results are more ambiguous. The study offers two main contributions. Firstly, it pioneers in testing the above mentioned predictions. Secondly, it proposes a novel strategy for identifying these biases among managers. Specifically, solid empirical evidence supported by diverse theoretical arguments suggests that people who run their own business (entrepreneurs) are particularly prone to showing overconfidence and optimism in their judgments. Alternatively, these biases were identified based on the amount of firm\'s stock owned by its manager. The available sample comprises 153 Brazilians firms observed from years 1998 to 2003. Different methods were applied for estimating the parameters of the empirical models, emphasizing a procedure based on the Generalized Method of Moments and known as System GMM, aiming at controlling endogeneity problems related to omitted variables, measurement errors and the likely simultaneous determination of some variables. The empirical evidence obtained does not favor the pecking order hypothesis. It is also not possible to distinguish any systematic impact of the proxies for managerial optimism/overconfidence on indicators of firm\'s market value or of its general level of investments. A quite significant result emerges from the empirical analysis, nevertheless: firms managed by individuals that were classified as optimists/overconfident reveal themselves, after intervening factors have been isolated, to be substantially more financially leveraged. This evidence is compatible with the central prediction of the set of theories considered and is robust to variations of the estimation method, specification of the empirical model and to differing operational definitions for the cognitive biases of interest. The economic significance allied to the statistical significance of the observed impact suggests that managerial optimism and overconfidence can indeed play a role in corporate decision making and, specifically, they may be important determinants of firms\' capital structure.

Essays in behavioural economics / Essais en économie comportementale

Cosic, Hana 15 December 2014 (has links)
Pourquoi prend-on ou non des risques ? Pourquoi ne recycle-t-on pas davantage ? En situation d'incertitude, quels prix immobiliers peut-on anticiper ? Pour d'éventuelles explications et pronostics concernant ces questions, les principes d'économie comportementale peuvent être invoqués. L'économie comportementale (CE) est l'association de la psychologie et de l'économie ayant pour but de donner une explication aux comportements observés sur les marchés, comportements humains faisant preuve de rationalité limitée et de raisonnements complexes (Mullainathan et Thaler, 2000). L'étude de l'économie comportementale a inspiré un grand nombre de théories différentes et a été utilisée dans de nombreuses applications empiriques et cette thèse suit le même schéma en explorant différentes applications de l'économie comportementale. Cette thèse développe trois nouvelles extensions de l'économie comportementale aux champs du management, du choix en termes de politiques et en termes de décision d'investissement immobilier. / Why do we take risks or we do not? Why do not we recycle more? Under uncertainty what do we expect will happen to our home prices? These and many other questions are asked on daily basis.For possible explanations and answers to these and similar questions principles of behavioural economics can be used. Behavioural economics (BE) is the combination of psychology and economics that investigates what happens in markets in which some of agents display human limitations and complications (Mullainathan and Thaler, 2000). Behavioural economics provides more realistic psychological foundations to increase explanatory and predictive power of economic theory. The study of behavioural economics has inspired a number of different theories and has been used in many applications, and this thesis follows the same path and investigates different applications of behavioural economics. This thesis explores three novel applications of behavioural economics to management, policy making and property investment decision making.

Des prescriptions aux comportements de protection du risque sismique en région Provence-Alpes-Côte d'Azur : développement d'un paradigme substitutif / From guidelines to earthquake protection behavior in the Provence-Alpes-Côte d'Azur region : development of a substitutive paradigm

Chesterman, Adam 20 November 2015 (has links)
Ces travaux, menés en région PACA, visent à comprendre comment amener les individus à se protéger du risque sismique. Dans ce cadre, nous avons exploré les effets comportementaux de la substitution de soi à autrui, puis observé les comportements effectifs de protection lors d’une étude de terrain. En interprétant la consigne de substitution en termes de comparaison sociale, le paradigme repose sur une distinction entre la contrôlabilité des effets d’un séisme et l’incontrôlabilité de son occurrence. Après avoir activé un élément central ou périphérique de la représentation sociale des séismes, il s’agit dans un premier temps d’inviter les individus à évaluer la probabilité des effets d’un séisme en consigne de substitution, et ensuite à évaluer la probabilité d’occurrence d’un séisme en consigne standard. Sous l’effet d’un biais d’optimisme comparatif, les individus déclarent systématiquement une probabilité des effets d’un séisme supérieure en consigne de substitution qu’en consigne standard. De même, selon un principe de consistance cognitive, ils déclarent une probabilité d’occurrence d’un séisme supérieure après avoir évalué la probabilité de ses effets selon une consigne de substitution. Les comportements de protection étaient ensuite mesurés à l’aide de la version française de l’échelle de préparation aux séismes. Les comportements de protection auto-déclarés sont significativement plus favorables suite à une réponse en consigne de substitution plutôt que standard. Toutefois, les effets du paradigme sur les comportements effectifs de protection sont plus mitigés. / The goal of this research, conducted in the PACA region, was to understand how to lead individuals to adopt earthquake protection behaviour. To this end, we explored the behavioural effects of self-other substitution, and observed actual protection behaviours in a field study. By interpreting self-other substitution in terms of social comparison, the paradigm relies on a distinction between the uncontrollability of an earthquake and the controllability of its consequences. After having activated a central or peripheral element of the social representation of earthquakes, participants are required to evaluate the probability of an earthquake’s effects in a substitutive context, and then the probability of an earthquake in a standard context. Comparative optimism leads participants to declare that the effects of an earthquake are more probable in a substitutive rather than standard context. Furthermore, a cognitive consistency principle seems to lead participants to declare that an earthquake is more likely after having evaluated the probability of its effects in a substitutive rather than standard context. Protection behaviours were measured using the French version of the Earthquake Readiness Scale. Self-declared protection behaviours were more favourable after a substitutive rather than standard answer. However, the effects on actual behaviours are mixed.

The relationship between intention to quit, pyschological capital and job satisfaction in the tourism industry in the Western Cape

Appollis, Verna Patricia January 2010 (has links)
Magister Commercii - MCom / The current research aims to identify the variables that influence turnover intentions. In particular, this research explored the concept of turnover intentions by investigating the mediating effects of job satisfaction and psychological capital amongst a sample of 70 employees involved in the tourism industry. The study highlights that employees within the tourism industry within the Western Cape were the most satisfied with work content, and the least satisfied with leadership / supervision. The results emanating from the current study indicate that there is a strong, inverse relationship between job satisfaction and turnover intention amongst tourism employees in the Western Cape. Furthermore, the study revealed that a statistically significant, inverse relationship exists between psychological capital and turnover intention. Multiple regression analysis revealed these variables significantly explained the variance in turnover intention. / South Africa

Investigating the experiences of gratitude during organizational change

Titus, Shirleen January 2010 (has links)
Magister Commercii - MCom / The interpretation of this qualitative study indicates that individuals, teams and the organisation can benefit through allowing focus of unlocking that which provides a positive stimulus during challenging times in organisational settings. For social scientists, and in particular behavioural scientists, including industrial psychologists that are interested in positive psychology, it is hoped that there is an invitation to grow this area of research further and to gain new insights and direction for what are the enablers to experience positive change and gratitude. / South Africa
