Um estudo petrográfico foi conduzido na seção rifte do Grupo Lagoa Feia, Cretáceo Inferior da Bacia de Campos, margem leste brasileira, como parte de um projeto regional integrado. Os principais constituintes das rochas analisadas são grãos siliciclásticos e vulcanoclásticos, oóides e pelóides estevensíticos, e bioclastos de bivalves e ostracodes. Este estudo foi focado nas rochas clásticas, estevensíticas e híbridas, desde que os estudos precedentes ficaram limitados às rochas carbonáticas que constituem os reservatórios produtores. A maior parte da sedimentação rifte foi intrabacial, com concentração da contribuição extrabacial na proximidade das falhas de borda dos blocos rifteados. Nos arenitos e conglomerados clásticos, a mistura de fragmentos vulcânicos arredondados com grãos de quartzo e feldspatos e fragmentos plutônicos angulosos indica a reciclagem de depósitos epiclásticos do início do rifte, combinada com sedimentos de primeiro ciclo erodidos de blocos soerguidos do embasamento granítico-gnáissico. Os oóides e pelóides estevensíticos foram formados em ambientes lacustres alcalinos rasos, levemente agitados por ondas ou correntes. Eles foram misturados com bioclastos de bivalves e ostracodes e com sedimentos clásticos em toda seção rifte. Esta re-deposição gravitacional foi promovida por movimentos tectônicos ao longo das margens dos blocos estruturais falhados. Os principais processos diagenéticos nos arenitos e conglomerados clásticos e nos arenitos híbridos são a cimentação e substituição de grãos por esmectita, zeolitas, calcita e dolomita, compactação limitada e dissolução de feldspatos, fragmentos vulcânicos e bioclastos. Os arenitos estevensíticos sofreram cimentação precoce e substituição dos oóides e pelóides por quartzo, calcita e dolomita, ou intensa compactação dos grãos estevensíticos dúcteis nas áreas não cimentadas. Arenitos e conglomerados vulcanoclásticos com porosidade intergranular parcialmente reduzida por franjas de esmectita e com alguma dissolução de grãos podem constituir reservatórios de qualidade regular. Arenitos estevensíticos e híbridos com dissolução de grãos estevensíticos, bioclastos e de cimento de calcita podem também constituir reservatórios, com qualidade potencial limitada pela conexão restrita de tais sistemas porosos. A compreensão dos controles espaciais e temporais sobre a evolução deposicional e diagenética das litologias rifte carbonáticas e não-carbonáticas, gravitacionalmente re-depositadas, irá contribuir para o estabelecimento de novas estratégias de exploração para a Bacia de Campos. / A petrographic study was conducted on the rift section of the Lagoa Feia Group, Lower Cretaceous of the Campos Basin, eastern Brazilian margin, as part of a regional, integrated project. The main primary constituents of the analyzed rocks are siliciclastic and volcaniclastic grains, stevensitic ooids and peloids, and bivalve and ostracod bioclasts. This study focused in the clastic, stevensitic and hybrid rocks, as previous studies were limited to the bioclastic rudstones and grainstones that constitute the producing reservoirs. Most rift sedimentation was intrabasinal, with extrabasinal contribution concentrated at the proximity of border faults along rifted blocks. In the clastic sandstones and conglomerates, the mixture of rounded volcanic fragments with angular quartz, feldspars and plutonic fragments indicates the recycling of early rift epiclastic deposits, combined with first-cycle sediments eroded from uplifted granitic-gneissic basement blocks. Stevensitic ooids and peloids were formed in shallow, alkaline lacustrine environments, slightly agitated by waves or currents. They were mixed throughout the rift section with bivalve and ostracod bioclasts, and with clastic sediments. This gravitational re-deposition was promoted by intense and recurrent tectonic movements along the margins of rifted structural blocks. The main diagenetic processes in clastic sandstones and conglomerates and hybrid arenites are cementation and grain replacement by smectite, zeolites, calcite and dolomite, limited compaction and dissolution of feldspars, volcanic fragments and bioclasts. Stevensitic arenites experienced early cementation and replacement of ooids and peloids by quartz, calcite and dolomite, or intense compaction of the ductile stevensitic grains in uncemented areas. Volcaniclastic sandstones and conglomerates with intergranular porosity partially reduced by smectite rims and some grain dissolution may constitute fair hydrocarbon reservoirs. Stevensitic and hybrid arenites with dissolution of stevensitic grains, bioclasts and calcite cement may also constitute reservoirs, with potential quality limited by the poor connection of such pore systems. The understanding of the space and time controls on the depositional and diagenetic evolution of the dominantly intrabasinal, gravitationally re-deposited rift carbonate and non-carbonate rocks will contribute to new exploration strategies for the Campos Basin.

A Bacia de Campos localiza-se na margem sudeste da costa brasileira, entre os paralelos 20.5⁰ e 23S⁰, com aproximadamente 100.000 km² de área. A bacia possui significativos volumes de hidrocarbonetos na seção pós-sal, sendo a grande maioria destas reservas em depósitos turbidíticos. Este trabalho teve como foco os arenitos depositados durante o Cretáceo, que ocupam a porção basal da Formação Carapebus da Bacia de Campos, visando à caracterização faciológica e petrográfica, interpretação do ambiente deposicional, distribuição espacial, e da qualidade dos reservatórios na região estudada. Para tal caracterização, foi feita a descrição e análise faciológica de testemunhos de sondagem de cinco poços, correlação entre os perfis geofísicos e os dados de rocha, elaboração de mapas de espessura, análise petrográfica de quarenta e nove lâminas delgadas e integração dos resultados, gerando um modelo geológico. A análise faciológica dos testemunhos definiu quinze fácies, interpretadas e agrupadas em três associações fácies (Canal Turbidítico, Lobo Turbidítico Proximal e Lobo Turbidítico Distal ou Overbank), de acordo com as características litológicas e padrões de empilhamento. A distribuição das fácies nos testemunhos está diretamente relacionada com a localização espacial do mesmo em relação ao canal turbidítico. Mapas de espessura foram gerados com base nos testemunhos e perfis geofísicos, e mostraram uma calha principal de deposição das areias com orientação aproximada NW-SE. Através da análise petrográfica foram definidas dezessete petrofácies de reservatório, que foram classificadas em quatro associações de petrofácies definidas com base no impacto na qualidade de reservatório (Porosas, Parcialmente Cimentadas, Cimentadas_Compactadas e Lutitos). Os principais fatores que controlam a qualidade de reservatório são a quantidade de intraclastos e pseudomatriz lamosa e de cimento carbonático. De forma geral, os crescimentos secundários atuaram de forma positiva na porosidade, sustentando o arcabouço e reduzindo a compactação mecânica. As associações de fácies de Canal Turbidítico e Lobo Turbidítico Proximal possuem as melhores qualidades de reservatório, apresentando a maior ocorrência da associação de petrofácies Porosa. Com base na correlação entre os dados de rocha (testemunhos e lâminas delgadas) e os perfis geofísicos, foram definidas assinaturas especificas para as melhores e piores qualidades de reservatório. Foi ainda possível observar que os poços A e D possuem as melhores qualidades de reservatório, estando localizados na parte central da calha principal de deposição do sistema turbidítico em questão. A integração das ferramentas utilizadas neste estudo contribuiu para a caracterização dos arenitos santonianos estudados, especialmente no sentido de compreender as heterogeneidades dos reservatórios, identificando as barreiras de fluxo que compartimentam os mesmos. / The Campos Basin is located in the southeastern margin of the Brazilian coast, between the parallels 20.5⁰ and 23⁰ S, with an area of approximately 100.000 km². The basin contains significant volumes of hydrocarbons in the post-salt section, with most of the reserves accumulated in turbidite deposits. This dissertation focuses on the study of sandstones deposited during the Cretaceous, comprising the basal Carapebus Formation. The main objectives are to characterize these sandstones and associated rocks in terms of facies and petrography, to interpret the depositional environment, spatial distribution and reservoir quality of these deposits. For this characterization, the description and facies analysis of cores from five wells was carried out, correlation between well-log and rock data, elaboration of thickness maps, petrographic analysis of forty-nine thin sections and integration of the results, leading to the proposition of a geological model. Facies analysis of the cores defined fifteen facies, interpreted and grouped into three facies associations (Turbidite Channel, Proximal Turbidite Lobe and Distal Turbidite Lobe or Overbank), according to the lithologic characteristics and stacking patterns. Facies distribution in the cores is directly related to their spatial location in relation to the turbidite channel. Thickness maps were generated based on cores and well logs, and they showed the deposition of sands along an approximately NW-SEoriented main channel. Through petrographic analysis seventeen reservoir petrofacies were defined, grouped into four petrofacies associations based on the impact on reservoir quality (Porous, Partly Cemented, and Cemented_Compacted and Lutites). The main controls on reservoir quality are the amount of mud intraclasts and pseudomatrix and carbonate cement. Overall, the presence of overgrowths had a positive impact on porosity, supporting the framework against mechanical compaction. The Turbidite Channel and Proximal Turbidite Lobe facies associations display the best reservoir qualities, with the common occurrence of Porous petrofacies association. Based on correlation of rock (cores and thin section) and well-log data, specific signatures were defined for the best and worst reservoir qualities. It was also observed that wells A and D have the best reservoir quality, being located in the central part of the main turbidite channel in this system. The integration of tools in this study contributed to the characterization of the studied Santonian sandstones, especially in order to understand heterogeneities in the reservoirs, identifying flow barriers and reservoir compartmentalization.

Objective: The purpose of this study was to develop and test psychometric properties of a Mealtime Interaction Clinical Observation Tool (MICOT) that could be used to facilitate assessment and behavioural intervention in childhood feeding difficulties. Methods: Thematic analysis of four focus groups with feeding and behaviour experts identified the content and structure of the MICOT. Following refinement, inter-rater reliability was tested between three healthcare professionals. Results: Six themes were identified for the MICOT, which utilises a traffic-light system to identify areas of strength and areas for intervention. Despite poor inter-rater reliability, for which a number of reasons are postulated, some correlation between psychologists’ ratings was evident. Healthcare professionals liked the tool and reported that it could have good clinical utility. Conclusion: The study provides a promising first version of a clinical observation tool that facilitates assessment and behavioural intervention in childhood feeding difficulties.

Aggression Replacement Training (ART) is a 10-week, multi-component intervention based in cognitive behaviour therapy (CBT), which aims to improve social competence. It has been applied internationally as part of offender rehabilitation (NOMS, 2010). However, more recent research has focused upon its application in school-based settings. The aim of the current research is to investigate the efficacy of ART when implemented in the UK with an adolescent sample in mainstream school settings. These sessions were facilitated by newly-trained staff from the Educational Psychology Service (EPS). A quasi-experimental design was employed to evaluate this initial pilot of the programme in one Local Authority. 41 participants across six settings were allocated to intervention (N=23) and wait-list control (N=18) conditions. The Social Skills Improvement System-Rating Scales (SSIS-RS), a multi-source measure, was used to assess the group member’s problem behaviours and social skills, with data gathered from teachers, parents and pupils themselves. The Sociomoral Reflection Measure-Short Form (SRM-SF) was also completed by the participants to ascertain their moral reasoning maturity. Non-parametric statistical tests demonstrated no significant improvements in the intervention participant’s social skills or problem behaviours. However, their moral reasoning ability did increase significantly from pre to post-test, achieving a large effect size (r=-0.64), which was not reflected in the data from the control group. In contrast to the quantitative findings, supplementary qualitative data gathered from the facilitators and group members involved in the ART programme demonstrated that all felt the intervention had resulted in positive outcomes for the young people. Factors which may have contributed to the success of the programme were also provided, including organisational support and group composition. Possible explanations for these findings, including methodological considerations and comparison with previous research are discussed and the implications of these findings in future practice and in guiding further research suggested.

CHAPTER ONE: The literature review critically evaluates research that has explored the psychological impact of parental acquired brain injury (ABI) on children. The review identifies a number of factors that affect the psychological well-being of children, including both adverse and protective factors. Evidence from the studies reviewed indicates that children are vulnerable to experiencing a range of emotional and behavioural difficulties following parental ABI. Clinical implications of the review findings are discussed, and directions for future research considered. CHAPTER TWO: The empirical paper aimed to explore the role of mutual support in Traumatic Brain Injury (TBI) survivors’ reformation of their identity among individuals attending a mutual support group. Using a Grounded Theory approach, a model of the participants experience was developed. The core category reflected how participants regained a sense of self through getting to know the “new” me. Five conceptual categories were identified in relation to identity formation: pre-injury self, comparison with others; accessing the social world of brain injury; purpose and self-efficacy; and acceptance of the post-injury self. The findings highlight a potentially important role for mutual support in identity reformation following TBI and implications for brain injury rehabilitation programmes are discussed. CHAPTER THREE: The third paper presents my personal and professional reflections of the research process and how my views have changed over the course of training. To illustrate these changes, elements of the grounded theory model proposed in the empirical paper (Chapter 2) have been applied to my own experiences. It is hoped that this approach will evidence my experience and exploration of getting to know the scientist-practitioner.

This thesis explores what ‘woman centred care’ means to both women and midwives and how this care is offered by midwives and perceived by women. It is set within the context of current health care policy and the way in which this impacts on both the organisation and implementation of maternity care. A flexible qualitative design was used to explore both women’s and midwives’ experiences of current maternity care over the full trajectory of maternity provision. A modified grounded theory approach was used framed within a feminist perspective. The fieldwork was undertaken in two phases. In phase one and interviews were undertaken with twelve women in early pregnancy, later pregnancy and after the birth; a total of twenty-five interviews with women were completed. Nine midwives were also interviewed in phase one. Preliminary and tentative categories were identified from both sets of interviews and were used to inform phase two of the study. Five women participated in the second phase of data collection. This included both informal, telephone contact and in-depth interviews spanning from early pregnancy until after the birth and included observation of their care in labour. The community midwives and delivery suite midwives specifically involved in their care were also interviewed. The data demonstrated a continued mismatch between the women’s and the midwives’ perspectives and it was evident that despite the policy drivers and consumerist rhetoric of ‘woman centred care’ and its original underpinning principles of continuity, choice and control, that this was not the overriding experience for the women who participated in the study. Data analysis highlighted some opportunities for negotiation but these were not explicitly recognised or realised by the women or midwives and there was little time or flexibility in the system to accommodate such opportunities. The increasing bureaucracy of the maternity care system also constrains continuity of carer over the full spectrum of the childbearing trajectory and reduces the potential for women to know the midwife who provided care. Thus for many midwives being ‘with the institution’ was more likely than ‘being ‘with woman’.

Since the late 1990s there has been an increasing focus on parenting ability, support and education which is reflected in policy, practice and research in the UK. This research analyses how nurses might intervene to provide this support, specifically in relation to crying baby and the role of nurses at NHS direct. It involves collection and analysis of data from NHS Direct call data in 2002, and solo focus group data in 2006. Within the wider tradition of grounded theory, the methodology includes use of discourse and thematic analytical approaches. The research analyses the means by which NHS Direct nurses make different use of the algorithms and organisational protocols to make decisions and give advice to parents with crying babies, how their clinical knowledge and experience influences these decisions, and how nurses explore parents’ ability to cope. This is seen within the organisational context of NHS Direct, a 24 hour government funded telephone service described as both a triage service and an advice/helpline service. Findings from the study indicate a degree of tension between the essentially humanistic nursing culture and the highly scripted, protocol driven rules based system that underpins NHS Direct. Despite this tension, nurses will sometimes combine their knowledge with that of the algorithm where the call is involved with eliminating emergencies. The same synthesis of knowledge is not apparent with the knowledge contained in the algorithm regarding non-medical, nonemergency, value-sensitive issues relating to parental coping with excessive infant crying. Findings suggest that NHS Direct nurses use the ‘crying baby’ algorithm differently and this variance is influenced by experience and familiarity with the algorithm. Adherence to the algorithm is perceived by nurses as safe in relation to the medical questions which exclude emergencies. The non-medical elements of the algorithm, which include prompting the nurse to ask about parent coping ability and the possibility of shaking their child, are treated differently and it is considered safe to not ask, or ask around the question and to not offer the advice prompted by the decision aid software. The algorithm prompt to assess parental coping ability is rarely successful in encouraging the nurse to do so overtly. From these findings, consideration might be given to enhancing nurses’ knowledge, skills and confidence, supported with appropriate supervision, to provide effective intervention in relation to value sensitive, non-medical issues such as parental coping ability and in handling the uncertainty such issues may yield. Allied to this would be establishing clarity and recognition of the inherently different, but not opposing functions of providing a triage service and an advice/ helpline service.
