This thesis examines the roles of governors within the contexts of the national framework for governance and the effect they have on schools. The field of research into the effects of school governors is an infant one. Little direct observation of governance has taken place and there is no true experimental research. In the absence of such work, the project developed a definition of effective governance through consideration of the descriptions of and prescriptions for governor activity. It used the definition to develop two research instruments. The first of these, a national questionnaire, produced some specific examples of a range of activities for governors and lead to the development of a second instrument. This, a schedule for semi- structured interviews, was applied to six case study schools. In these studies, governors and headteachers were interviewed conceming the characteristics of their goveming bodies and the outcomes for the schools were set against these characteristics. What emerges from these comparisons are some clear associations between effective outcomes and certain governor activities. These include training, monitoring, clear support for the school, the degree of trust gained with the staff, detailed knowledge of the school, and participation in school development planning. Overall, the conclusions point to connections between the manner in which governors conduct themselves and their business and the successes of the school that they govern.

Classifying pipe cracks by size from their pulse-echo ultrasonic signal is difficult but highly significant for the defect evaluation required in pipe testing and maintenance decision making. For this thesis, a binary Support Vector Machine (SVM) classifier, which divides pipe cracks into two categories: large and small, was developed using collected ultrasonic signals. To improve the performance of this SVM classifier in terms of reducing test errors, we first combined the Sequential Backward Selection and Sequential Forward Selection schemes for input feature reduction. Secondly, we used the data dependent kernel instead of the Gaussian kernel as the kernel function in the SVM classifier. Thirdly, as it is time-consuming to use the classic grid-search method for parameter selection of SVM, this work proposes a Kernel Fisher Discriminant Ratio (KFD Ratio) which makes it possible to more quickly select parameters for the SVM classifier.

This thesis describes the relationship between adult attachment style, coping strategies, identity development and perception of social support. 107 participants answered four self-report questionnaires examining their attachment style, coping strategies, identity development status and perception of social support. Correlation analyses were used. Results showed secure attachment to significantly positively correlate with identity moratorium and to negatively correlate with identity foreclosure. Avoidant attachment significantly positively correlated with denial and mental disengagement and negatively correlated with seeking social support. Individuals with high avoidant attachment scores were more likely to have high scores for identity diffusion, more likely to perceive fewer available social supports and were less likely to be satisfied with this support. Anxious ambivalence positively correlated with denial and mental, behavioural and alcohol/drug disengagement, and negatively correlated with active and planning which are pro-active coping strategies. Anxious ambivalence positively correlated with identity diffusion and negatively with identity foreclosure. Individuals with high anxious ambivalence scores were more likely to be dissatisfied with social support. Overall, secure attachment was found to correlate with acknowledging the need for an identity search. Insecure attachment was found to relate to less effective coping methods, to correlate with not acknowledging the need for an identity search and dissatisfaction with social support. Results are considered in terms of attachment styles and applications, for example in therapeutic settings.

Refugees come from diverse backgrounds and the issues they face depend on their particular circumstances. Some of the issues refugees face include cultural shock, language difficulties, lack of established networks and often discrimination. Christchurch has a growing refugee community with their own social needs. The survey detailed in this dissertation was undertaken in response to the Canterbury Refugee Council identifying the lack of comprehensive data available for refugee resettlement outcomes in Christchurch. The aim was to gain a better understanding of the living conditions experienced by the refugee community in Christchurch. The participants were from the four main refugee groups resettled over the past decade, namely people coming from Afghanistan, Kurdistan area, Ethiopian, Somalia and Eritrea. This survey was undertaken at a time when international literature concludes that refugees are one of the most vulnerable groups in society and emphasises the vital role that housing alongside other factors have on positive resettlement outcomes. A quantitative approach was adopted to gather information rather than test hypotheses; it was designed to investigate housing, neighbourhood and sources of income. It also included what, if any, social support is available from the wider community, and explored some of the main current problems faced by the refugee families. The survey concludes that despite good intentions and some successes, there are still many obstacles for refugees resettling into their new environment. Refugees continue to experience chronic unemployment and struggle to access suitable housing for their families. The issues raised in this survey highlight the importance of acknowledging and responding to refugee diversity.
