The Use of Mindfulness-Based Cognitive Therapy for Patients with Inflammatory Bowel Disease
Background: Inflammatory Bowel Disease (IBD) is a group of chronic gastrointestinal diseases with a relapsing nature. The two main types are Crohn’s disease (CD) and ulcerative colitis (UC). Both CD and UC patients experience very similar and distressing symptoms: acute abdominal pain, vomiting, malnutrition, fever, fatigue, diarrhoea and rectal bleeding. These symptoms are disabling and have a severe impact on physical and psychosocial wellbeing. Around 30% of patients suffer from moderate to severe psychological distress and have difficulties coping with the illness even in remission. However, it appears that mental health is overlooked by clinicians who often focus on physical gastrointestinal symptoms only.
Mindfulness-Based Cognitive Therapy (MBCT) is evidence based, group psychological intervention that has been successful in reducing depression and anxiety scores in patients with depression while improving overall quality of life. However, MBCT has never been tested in the IBD population before.
PhD question: Can MBCT be used as an adjunct therapy to IBD symptom management, for improving IBD patients' general well-being and quality of life?
Aims and objectives: The overall aim of the thesis was to develop and collate the evidence for a definitive randomised controlled trial (RCT) testing the effectiveness of MBCT for patients with inflammatory bowel disease (IBD). The thesis brings together six publications. The six publications were integrated into four objectives that collectively contributed in answering the overall PhD question.
Results: The findings from the first three publications highlighted the disease-related concerns and psychological needs for patients with IBD. The findings from the last three publications highlighted how feasible it is to use MBCT in IBD and emphasised the IBD patients’ perspectives about MBCT.
Conclusion: The thesis concluded that a definitive RCT of MBCT for IBD patients is both feasible and acceptable
ORGANIZATIONAL THEORY PERSPECTIVES TOWARD SUCCESS IN DYNAMIC ENVIRONMENTS
How can special operations forces balance present-day readiness with the requirement to stay ahead of potential revolutionary changes in the operating environment? This question presents a challenge to any organization—military or otherwise—that seeks to sustain a competitive advantage over time. The challenges of tomorrow are different from those of today, and organizations in changing environments must deal with the often-competing requirements for present and future success. Within the field of organizational study resides a deep and diverse body of work that addresses this issue from varying perspectives. This thesis reviews three of these perspectives—ambidexterity, the dynamic capabilities view, and organizational ecology—and extracts useful concepts for United States Special Operations Command to consider as it plans for the increasingly dynamic environments of the twenty-first century. Each field is reviewed in some detail, and key concepts or frameworks are reviewed and assessed for applicability. Ultimately, a concise summary of conclusions is provided along with recommendations for further study into matters that impact special operations’ readiness in environments of evolutionary and revolutionary change.http://archive.org/details/organizationalth1094561264Lieutenant Commander, United States NavyApproved for public release; distribution is unlimited
Effect of motion frequency spectrum on subjective comfort response
In order to model passenger reaction to present and future aircraft environments, it is necessary to obtain data in several ways. First, of course, is the gathering of environmental and passenger reaction data on commercial aircraft flights. In addition, detailed analyses of particular aspects of human reaction to the environment are best studied in a controllable experimental situation. Thus the use of simulators, both flight and ground based, is suggested. It is shown that there is a reasonably high probability that the low frequency end of the spectrum will not be necessary for simulation purposes. That is, the fidelity of any simulation which omits the very low frequency content will not yield results which differ significantly from the real environment. In addition, there does not appear to be significant differences between the responses obtained in the airborne simulator environment versus those obtained on commercial flights
Guidelines for the analysis of student web usage in support of primary educational objectives
The Internet and World Wide Web provides huge amounts of information to individuals with access to it. Information is an important driving factor of education and higher education has experienced massive adoption rates of information and communication technologies, and accessing the Web is not an uncommon practice within a higher educational institution. The Web provides numerous benefits and many students rely on the Web for information, communication and technical support. However, the immense amount of information available on the Web has brought about some negative side effects associated with abundant information. Whether the Web is a positive influence on students’ academic well-being within higher education is a difficult question to answer. To understand how the Web is used by students within a higher education institution is not an easy task. However, there are ways to understand the Web usage behaviour of students. Using established methods for gathering useful information from data produced by an institution, Web usage behaviours of students within a higher education institution could be analysed and presented. This dissertation presents guidance for analysing Web traffic within a higher educational institution in order to gain insight into the Web usage behaviours of students. This insight can provide educators with valuable information to bolster their decision-making capacity towards achieving their educational goals
How candidate characteristics matter : Candidate profiles, political sophistication, and vote choice
Our study examines the influence of various candidate characteristics (sociodemographic profile, competence and experience, issue positions, and party affiliation) on voters' preference for a candidate, and investigates the impact of voters' levels of political sophistication on their likelihood of considering various candidate characteristics voters when deciding whom to support. Using data from the 2015 Finnish National Election Study, this study is situated within the complex Finnish open list system with many candidates at display and mandatory preference voting. We find that voters mostly argue to make their choice based on candidate characteristics with direct politically relevant information such as candidate party affiliation and issue positions. Candidate sociodemographic profile has relatively little stated impact. Overall, voters with higher levels of political sophistication tend to be more likely to consider a broad range of candidate characteristics. When investigating the relative impact of each candidate characteristic (that is, their impact relative to the other candidate characteristics) on voting behaviour, political sophistication increases the likelihood of saying to rely on candidate characteristics that are more demanding in terms of information processing such as competence and experience, and issue positions. Our analyses also show how different measures of political sophistication have distinct effects.Peer reviewe
Policy or person? : The electoral value of policy positions and personal attributes in the Finnish open-list system
Under open-list proportional representation (OLPR), individual candidates compete for personal votes and representation has a distinctly individualistic dimension. This article provides a unique analysis of this individualistic representational dimension, by comparing the effects of policy positions with personal vote-earning attributes on individual electoral success within the context of the Finnish OLPR. The study confirms that personal attributes related to experience, locality and celebrity status have a strong positive effect on candidates’ ability to attract personal votes. On a more novel account, it also demonstrates that even under decidedly complex electoral settings, policy positions matter for candidates’ electoral fortunes, and that candidates who take on moderate positions within the context of their respective party are more successful than candidates who deviate from the party-median.Under open-list proportional representation (OLPR), individual candidates compete for personal votes and representation has a distinctly individualistic dimension.

Participants' perspectives on mindfulness-based cognitive therapy for inflammatory bowel disease:a qualitative study nested within a pilot randomised controlled trial
Background: Mindfulness-based interventions have shown to improve depression and anxiety symptoms as well as quality of life in patients with inflammatory bowel disease (IBD). However, little is known about the experiences of this group of patients participating in mindfulness interventions. This paper sets out to explore the perspectives of patients with IBD recruited to a pilot randomised controlled trial (RCT) of mindfulness-based cognitive therapy (MBCT) about the intervention. Methods: In a qualitative study nested within a parallel two-arm pilot RCT of mindfulness-based cognitive therapy for patients with IBD, two focus group interviews (using the same schedule) and a free text postal survey were conducted. Data from both were analysed using thematic analysis. Data and investigator triangulation was performed to enhance confidence in the ensuing findings. Forty-four patients with IBD were recruited to the pilot RCT from gastroenterology outpatient clinics from two Scottish NHS boards. Eighteen of these patients (ten from mindfulness intervention and eight from control group) also completed a postal survey and participated in two focus groups after completing post intervention assessments. Results: The major themes that emerged from the data were the following: perceived benefits of MBCT for IBD, barriers to attending MBCT and expectations about MBCT. Participants identified MBCT as a therapeutic, educational and an inclusive process as key benefits of the intervention. Key barriers included time and travel constraints. Conclusions: This qualitative study has demonstrated the acceptability of MBCT in a group of patients with IBD. Participants saw MBCT as a therapeutic and educational initiative that transformed their relationship with the illness. The inclusive process and shared experience of MBCT alleviated the sense of social isolation commonly associated with IBD. However, time commitment and travel were recognised as a barrier to MBCT which could potentially influence the degree of therapeutic gain from MBCT for some participants.</p
