Research psychologists often complain that practitioners disregard research evidence whilst practitioners sometimes accuse researchers of failing to produce evidence with sufficient ecological validity. The tension that thus arises is highlighted, using the specific illustrative examples of two treatment methods for post-traumatic disorder (PTSD): Eye-Movement Desensitisation and Reprocessing (EMDR) and exposure based interventions. Contextual reasons for the success or failure of particular treatment models that are often only tangentially related to the theoretical underpinnings of the models are discussed. Suggestions regarding what might be learnt from these debates are put forward and implications for future research are discussed.

The optimum ordering strategies for the coded V-BLAST system with capacity achieving temporal codes on each stream are studied in this thesis. Mathematical representations of the optimum detection ordering strategies for the coded V-BLAST under instantaneous rate allocation (IRA), uniform power/rate allocation (URA), instantaneous power allocation(IPA) and instantaneous power/rate allocation (IPRA) are derived. For two transmit antennas, it is shown that the optimum detection strategies are based on the per-stream before-processing channel gains. Based on approximations of the per-stream capacity equation, closed-form expressions of the optimal ordering strategy under the IRA at low and high signal to noise ratio (SNR) are derived. Necessary optimality conditions under the IRA are given. Thresholds for the low, intermediate and high SNR regimes in the 2-Tx-antenna system under the IPRA are determined, and the SNR gain of the ordering is studied for each regime. Performances of simple suboptimal ordering strategies are analysed, some of which perform very close to the optimum one.

Background: The death of a child has been found to have long term consequences for both individual and family functioning. This is particularly true for bereaved siblings who have been found to be at increased risk of developing mental health difficulties in later life. Literature on parental bereavement proposes that the parenting phenomenon, such as replacement child syndrome, subsequent child syndrome and the parenting paradox, which can emerge after the death of a child, may account for this. However, there is very little research on these labels of observed parenting phenomenon and, as a result, any hypothesis offered remains under elaborated. In addition, limited evidence suggests that, due to the sudden, unexpected and unexplained nature of the loss, SIDS parents are more likely to experience a greater degree of distress and adjustment difficulties than other perinatally bereaved populations. Given this, it could be hypothesised that SIDS parents may be likely to experience these parenting phenomena. Despite this, however, SIDS remains a neglected area of research. Aims: As a consequence of this research gap, the study aims to explore mothers’ experiences of parenting in their transition from being a parent unaffected by Sudden Infant Death Syndrome to a parent affected by Sudden Infant Death Syndrome. Methodology: Semi-structured interviews were conducted with seven mothers who had experienced an incident of Sudden Infant Death Syndrome. The interviews were then transcribed and analysed using Interpretative Phenomenological Analysis (IPA). Results: Five master themes emerged from the analysis: ‘Channelling the Parent Within’, a naturally developing and responsive parenting style that is facilitated by internal mechanisms, such as flexibility and confidence; ‘Parenting Outside of Yourself’, a parenting style that develops in the aftermath of a SIDS event, which is characterised by self doubt and a reliance on external mechanisms such as reassurance and restriction; ‘Restoration Through You’, the restorative effect of the subsequent and surviving children, which allows vindication and re-establishes happiness; ‘The Bitter Restoration’, a restoration that encompasses internal knowledge and external evidence of loss, including a disrupted family composition and a continued awareness of existential threat; ‘A Disruptive Appreciation’, the development of a greater appreciation for the subsequent and surviving children that impacts discipline and incorporates indulgence. These, along with the subthemes contributing to them, are presented as a narrative account. Conclusion: The results imply that mothers who have experienced a SIDS event shift into a permissive and anxious style of parenting which is characterised by safety behaviours. A model of parenting in the aftermath of SIDS has been proposed in order to explain the underlying cognitions and processes which drive this behaviour and the factors which serve to maintain it. By doing this it is hoped that, when working with bereaved parents and siblings, clinicians will be better positioned to frame parenting practices and intervene at a cognitive level.

Background: Guidelines for the treatment of Post-Traumatic Stress Disorder recommend 8-12 session of trauma-focused CBT or EMDR, however there is an extensive body of literature criticising the PTSD paradigm and usefulness of recommended therapies in treating PTSD in the 'real world', particularly with the complex presentations of refugees . Alternative models for 'complex' PTSD have been proposed, as have transtheoretical phased stages for treatment. To date there has been no research into refugees' experience of trauma-therapy. Leaving a significant gap in understanding of how trauma therapy works. Aims: With this gap in the research in mind, and in line with the current focus on service user involvement in research, this study aims to investigate refugees' experiences of trauma-therapy. Methodology: Semi-structured interviews were conducted with six refugees who were coming towards the end of trauma-therapy with a specialist trauma service. The transcripts of the interviews were then analysed using Interpretative Phenomenological Analysis (IPA). Results: Six master themes emerged from analysis: 'Therapy as a light in a dark place', 'Rebuilding a shattered sense of self', 'A changing relationship with the world and others', 'Escaping the past to pursue a future', 'A journey from sceptic to convert' and 'From an unknown mystery to a known mystery'. These master themes along with the subordinate themes are expanded into a narrative account of participants' experiences. Implications & Conclusion: Amongst numerous implications for clinical practice the need for support to engage in therapy, thorough explanation of therapy and pre-empting of possible conflicts and difficulties arising were identified. Allowing time to build a therapeutic relationship, the usefulness of the PTSD construct for individuals and the importance of the 'non-specific' factors of therapy in addition to the teaching of techniques to manage symptoms were also found to be of importance. This study has made an important contribution to knowledge about refugees' experiences of therapy for trauma.

As project management (PM) and information technology (IT) evolved over the last decades, an increasing number of project management software products have emerged. Project managers in IT consulting can improve the success of projects through the utilization of such software. However, the diversity of software available cannot sensibly be grasped by a single individual. Based on this context, the study aims to examine the key considerations in the selectionof project management software in IT consulting from the project managers' perspective. A literature review identifies key aspects of IT consulting projects that may be relevant to the software selection. No evidence was found that provided a view on the process of the selection of PM software in IT consulting itself. The review also unveils the lack of common terminology in regard to PM software. The study addresses these gaps by utilizing interpretative phenomenological analysis (IPA) to understand the experiences made by project managers. To gather data, 17 semistructured interviews were conducted with experienced project managers. Thematic analysis was used to develop an understanding of the process employed by project managers in the software selection and the considerations they make along the way. The findings were synthesized to create a process guide, supported by a checklist and the working definition of key terminology. This study adds a broader perspective to the field of PM software through the application of qualitative methodology in an otherwise quantitatively dominated field of research. It addresses the lack of existing knowledge on the perspective of the project manager in the selection process through the generation of a 6-staged process guide. The detailed considerations of project managers were compiled into a checklist of selection criteria. These two also contribute to practice by providing a structured approach to PM selection for practitioners. The third output is a working definition of project management software as used in practice, which simplifies an exchange of knowledge between theory and practice.

Researchers have stressed the importance of addressing the social/emotional needs of early childhood (EC) children, including the development of resilience; however, some U.S. school personnel focus more on academics than on these needs. When young children possess these skills, they can handle social/emotional challenges later in life. The purpose of this qualitative bounded case study was to explore school social workers' (SWs) perspectives about resilience in EC settings. Research questions focused on knowledge of existing programs, participants' perceptions of the successes and challenges of working with EC students, and their recommendations to improve EC students' education. Bronfenbrenner's ecological systems theory and O'Neill's and Gopnik's work on needs of young children informed this study. Five elementary school SWs with at least 6 years' experience from 5 districts in the U.S. Midwest participated in 2 semistructured individual interviews. Interpretive phenomenological analysis, involving first-cycle, transition, and second cycle coding, was used to identify themes. SWs' experiences indicated a need for a clear definition of resilience, and needs of young children, including EC programs that develop psychological resilience of children's thoughts and an increase in adults to promote resilience. Additional research may expand and enhance educators' and families' understanding of resilience and help develop research-based preventive programs and strategies to foster psychological resilience in young children. These endeavors may enhance positive social change by adding components of psychological resilience to EC programs for school personnel and students and in parent/family workshops, which may result in sound mental health practices that enable them to become productive members of society.

Bioprocesses for air pollution control can generally be categorized as bioscrubber, biofilter, and biotrickling filter systems. These processes have been proven to be economical and effective for control of volatile organic compounds (VOCs) with concentrations of <1,000 mg C m-3 in gas streams. First, an activated sludge aeration tank (W x L x H = 40 x 40 x 300 cm) with a set of 2 mm orifice air spargers was utilized to treat gas-borne VOCs (toluene, p-xylene, and dichloromethane) in air streams. The effects of liquid depth (Z), aeration intensity (G/A), the overall mass transfer rate of oxygen in clean water (KLaO2), the Henry¡¦s law constant of the tested VOC (H), and the influent gaseous VOC concentration (C0) on the efficiency of removal of VOCs were examined and compared with a literature-cited model. Results show that the measured VOC removal efficiencies and those predicted by the model were comparable at a G/A of 3.75 ¡V 11.25 m3 m-2 hr-1 and C0 of around 1,000 ¡V 6,000 mg m-3. Experimental data also indicate that the designed gas treatment reactor with KLaO2 = 5 ¡V 15 hr-1, could achieve > 85% removal of VOCs with H = 0.24 ¡V 0.25 at an aerated liquid depth of 1 m, and > 95% removal of dichloromethane with H = 0.13 at a 1 m liquid depth. The model predicts that, for gas treatment in common activated sludge tanks, with KLaO2 = 5 ¡V 10 hr-1, depth = 3 ¡V 4.5 m, G/A = 9 ¡V 18 m3 m-2 hr-1, > 92% VOC removal can be achieved with operating parameters of Z of 3.0 m and KLaVOC/(G/A) of about 0.28 m-1, for VOCs with H < 0.3, such as most oxygen-containing hydrocarbons with low molecular weights, and benzene, toluene, ethylbenzene, and dichloromethane. Second, an activated sludge aeration tank and a sieve-plate column with six sieve plates were utilized to treat gas-borne VOCs in air streams. The tank was used for the biodegradation of the absorbed VOCs from the column which utilized the activated mixed liquor drawn from the tank as a scrubbing liquor. This research proposed a model for VOC absorption to a down-flow activated sludge liquor in a sieve-plate column. The experimental setup consisted of a pilot-scale activated-sludge tank and a sieve-plate tower, as demonstrated. The sieve-plate tower was constructed from a 25 x 25 x 162 cm (W x L x H) acrylic column with six custom-made sieve plates. Each plate has 382 holes which are 3 mm in diameter arranged on a square pitch. The holes give an open area of 3.82% of the whole plate area for gas flow. Two 25 mm-i.d. down-comer pipes were also equipped to allow for the downflow of the activated sludge liquor. Ports were provided at the column inlet, outlet, and each plate for gas and liquid sampling. Experiments were conducted and the model verified based on the results of tests on the removal efficiencies of isopropyl alcohol (IPA), toluene and p-xylene in the system operated at a range of influent VOC concentrations, air application rates, and liquid/gas flow ratios (L/G). The model developed by a material balance for the gaseous- and liquid-VOC over each plate of the column was developed and experimentally verified in this study. Superficial gas velocity over the column plate (U), number of plates (N), volumetric liquid-phase VOC-transfer coefficient (KLaVOC), aerated liquid depth over the plate (Z), volumetric liquid/gas flow-rate ratio (L/G), dimensionless Henry¡¦s law coefficient of the VOC to be absorbed (H), VOC content of the influent scrubbing liquor (xN+1), and the biodegradation rate constant of the VOC in the activated sludge mixed liquor (k) are among the affecting parameters to the effectiveness of the VOC removal. Model application by the model for effects of affecting parameters on the VOC removal effectiveness indicates that L/G, plate number N, biodegradation rate constant k, Henry¡¦s law constant of VOC H are among the important ones. A L/GH of greater than 2 and N of around 6 are enough for the effective (>90%) removal of the influent VOCs with H < 0.01 if no biodegradation occurred in the column. However, a N of over 16 is required for the influent VOCs with H of around 0.2. Biodegradation with a rate constant of around 100 hr-1 in the column greatly improves the column performance.

Aim: Whilst there is a wide range of research that explores ethics guidance and committee perspectives of research ethics processes, there is a lack of research into trainee experiences. The aim of this study was to explore Trainee Clinical Psychologists experience of the research ethics process and provide a platform to those voices. It was hoped that this research may be able to create a deeper understanding of applicants’ experiences, in which both positive and negative experiences of the application process can be shared and explored. This understanding could then potentially support ethics committees, training courses and applicants to work together and thus improve the application process and resulting research at a national level within the context of Clinical Psychology training. Method: This study adopted a qualitative approach in conducting semi-structured interviews with three Trainee and three Newly Qualified Clinical Psychologists who had applied for ethical approval for their Doctoral thesis. Interpretative Phenomenological Analysis (IPA) was used in an attempt to illuminate the lived experience of applying for research ethical approval. Results: From the analytic procedure, three main themes emerged regarding the experience of research ethics processes from participants’ accounts: The emotional intensity and personal impact of the ethics process; Responses to and ways of managing the ethics process; and Challenges within the ethics process. Implications: This study highlights the importance of recognising the impact of the relationships between Trainee Clinical Psychologists, Clinical Psychology training courses and Research Ethics Committees upon trainees’ journey through the research ethics process. A ‘them and us’ dynamic is being maintained by misunderstandings about each other’s roles, uncertainty and stereotyping, amongst other factors. Potential ways to change this dynamic and improve the research ethics process during clinical Psychology Training has been explored.

Autism-spectrum disorders (ASDs) are a group of neurodevelopmental disorders that are becoming increasingly more prevalent. A diagnostic criterion for autism is the presence of restricted, repetitive behaviours (RRBs), one of which is the intense fascinations for virtually any topic: circumscribed interests (CIs). CIs have the potential to be used for motivational purposes. This study employed semi-structured interviews using Interpretative Phenomenological Analysis (IPA) with individuals with ASDs and their parents. In total, 11 families participated in this study, comprising 33 individuals (16 parents and 17 individuals with ASDs). This study found five themes: He's Very Unique; They Don't Realize that Not Everyone Lives and Thinks the Same Thing All the Time; We Couldn't even Pronounce the Names of These Dinosaurs, and Jason was Telling Us; You Can't Change Them, You Can Only Love Them; and So I Can Do My Job at the Same Time and Observe the Weather at the Same Time.
