Effects of caffeine on persuasion and attitude change:the role of secondary tasks in manipulating systematic message processing

Two experiments are reported that examine the effects of caffeine consumption on attitude change by using different secondary tasks to manipulate message processing. The first experiment employed an orientating task whilst the second experiment employed a distracter task. In both experiments participants consumed an orange-juice drink that either contained caffeine (3.5?mg/kg body weight) or did not contain caffeine (placebo) prior to reading a counter-attitudinal communication. The results across both experiments were similar. When message processing was reduced or under high distraction, there was no attitude change irrespective of caffeine consumption. However, when message processing was enhanced or under low distraction, there was greater attitude change in the caffeine vs. placebo conditions. Furthermore, attitudes formed after caffeine consumption resisted counter-persuasion (Experiment 1) and led to indirect attitude change (Experiment 2). The extent that participants engaged in message-congruent thinking mediated the amount of attitude change. These results provide evidence that moderate amounts of caffeine increase systematic processing of the arguments in the message resulting in greater agreement.

The process of strategic change:a management perspective

This thesis is concerned with the management processes concerned with complex strategic decision in organisations. The research has sought to explore these processes by taking as its focus the reconstruction of decision processes a) on the basis of an historical study of an industry and in particular a major company in that industry; and b) the perception and understanding of strategic decision processes and change by managers involved in companies in that industry. The main body of analysis and theoretical contributions arise from the detailed analysis of extended depth interviews with managers carried out in 1980 and 1983 which trace thirteen years of the strategic development of a firm. In so doing, extensive use is made of verbatim accounts by managers of events and their interpretation of events. This is then compared with data gathered from.similar interviews with managers of two other companies and examined in the light of existing research and theory in the field. The thesis both provides a detailed insight into the processes associated with the identification and resolution of complex strategic issues and also generates a body of theory concerning the mechanisms by which strategic decisions and the processes of strategic change are interwoven with the cultural and political fabric of organisations. The thesis is divided into four parts. The first part deals with the background to the research, provid1ng a fuller summary of the purpose, structure and content of the thesis and a discussion of relevant previous research and the methodology employed herein. The second part mainly provides case studies of the industry and the main company studied. The third part is a detailed presentation and analysis of data. The fourth part is a synthesis of the findings and consolidation of the theoretical interpretation advanced in the thesis.

Change in third sector organisations: the impact of European Union funding in cross-national perspectives

This is a study of third sector organisations and organisational change resulting from European Union funding. While there is a growing body of research which shows how governmental funding can contribute to the organisational challenges that third sector organisations encounter, research on how European Union funding affects third sector organisations is limited. This thesis contributes towards closing this gap in knowledge by identifying a number of organisational changes which can be attributed to the use of European Union funding. A qualitative approach was taken to explore organisational change resulting from the use of URBAN II funding in nine third sector organisations which were studied in the context of the URBAN II programmes of Belfast, Berlin and Bristol. The conceptual framework for this study draws on organisation theory and resource dependence theory, together with concepts of co-production and multi-level governance. URBAN II funding was found to have affected organisational structures, processes, services, goals and participants, as well as the interactions of organisations with their external environment. In contrast to earlier research however, the findings from this study suggest that many of these organisational changes improved the capacity of third sector organisations to carry out their work. The cross-national comparison of the findings further showed that organisational impacts resulting from the use of URBAN II funding can vary significantly between different countries. Programme Managers were found to have played a critically important' role in enabling third sector organisations to obtain benefits from URBAN II funding. Many positive organisational changes arose from a close collaboration between Programme Managers and third sector organisations. Conversely, many negative organisational impacts were found to be due, not to the regulations associated with European funding, but primarily to the approach adopted by the Programme Managers and Local Development Partnerships towards engaging third sector organisations in programme delivery.

Gender differences in the relationships between bullying at school and unhealthy eating and shape-related attitudes and behaviours

Background. Previous research has found links between being a victim of bullying and reporting more unhealthy eating behaviours and cognitions, particularly in girls. However, little is known about the factors that might mediate these relationships. Aim. The present study compared the relationships between bullying, emotional adjustment, restrained eating, and body dissatisfaction in adolescent boys and girls. Sample/method. Self-report data were collected from a sample of 11- to 14-year-olds (N= 376) on experiences of bullying, emotional symptoms, and unhealthy eating and shape-related attitudes and behaviours. Results. Bullying, emotional symptoms, restrained eating, and body dissatisfaction were all correlated. Emotional symptoms were found to significantly mediate the relationships between verbal bullying with body dissatisfaction in girls but not in boys. Conclusions. Findings suggest that the experience of being verbally bullied places adolescent girls at risk of developing emotional problems which can then lead to body dissatisfaction. Longitudinal research is necessary to disentangle these pathways in more detail to facilitate the development of informed interventions to support children who are being bullied.

Partnering with governments and other institutions:driving change in diabetes care

The human and material cost of type 2 diabetes is a cause of increasing concern for health professionals, representative organisations and governments worldwide. The scale of morbidity and mortality has led the United Nations to issue a resolution on diabetes, calling for national policies for prevention, treatment and care. There is clearly an urgent need for a concerted response from all interested parties at the community, national and international level to work towards the goals of the resolution and create effective, sustainable treatment models, care systems and prevention strategies. Action requires both a 'bottom-up' approach of public awareness campaigns and pressure from healthcare professionals, coupled with a 'top-down' drive for change, via partnerships with governments, third sector (non-governmental) organisations and other institutions. In this review, we examine how existing collaborative initiatives serve as examples for those seeking to implement change in health policy and practice in the quest to alleviate the health and economic burden of diabetes. Efforts are underway to provide continuous and comprehensive care models for those who already have type 2 diabetes; in some cases, national plans extend to prevention strategies in attempts to improve overall public health. In the spirit of partnership, collaborations with governments that incorporate sustainability, long-term goals and a holistic approach continue to be a driving force for change. It is now critical to maintain this momentum and use the growing body of compelling evidence to educate, inform and deliver a long-term, lasting impact on patient and public health worldwide. © 2007 The Authors.

The 'law of requisite variety' may assist climate change negotiations:a review of the Kyoto and Durban meetings

Ashby wrote about cybernetics, during which discourse he described a Law that attempts to resolve difficulties arising in complex situations – he suggested using variety to combat complexity. In this paper, we note that the delegates to the UN Framework Convention on Climate Change (UNFCCC) meeting in Kyoto, 1997, were offered a ‘simplifying solution’ to cope with the complexity of discussing multiple pollutants allegedly contributing to ‘climate change’. We assert that the adoption of CO2eq has resulted in imprecise thinking regarding the ‘carbon footprint’ – that is, ‘CO2’ – to the exclusion of other pollutants. We propose, as Ashby might have done, that the CO2eq and other factors within the ‘climate change’ negotiations be disaggregated to allow careful and specific individual solutions to be agreed on each factor. We propose a new permanent and transparent ‘action group’ be in charge of agenda setting and to manage the messy annual meetings. This body would be responsible for achieving accords at these annual meetings, rather than forcing this task on national hosts. We acknowledge the task is daunting and we recommend moving on from Ashby's Law to Beer's Viable Systems approach.
