The environment of urban schools can be characterized by high teacher turnover; high student drop out rates; low performance by students on standardized tests; and a shifting demographic in student population. New teachers graduating from teacher education pre-service programs will almost surely teach in urban schools with students from different socio-economic, racial, and ethnic backgrounds than themselves. Students in these urban school environments often do not feel a connection to their teachers or their schools. This study shares oral narratives from teachers, students, a principal, and staff members from a high school for recent immigrants in the South Central United States which defies these odds. The interviews focus on how care is experienced by the teachers and students and sheds light on how teachers and students define the practice of care. Further the study looks at how school leadership and policies can impede and enhance the practice of care in the school setting. Among the several major findings, it was found that teachers and students both have a need, even a longing, for connection. The results provide implications for classroom practice, professional development, school leadership & decision-making practices, school culture, technology use, and overall school performance. / text

A study of the Strategic Sewage Disposal Scheme (SSDS) Stage 1 Tunnel F in Hong Kong was carried out as it is a great example of deep sub-sea hard rock TBM tunnelling through unfavourable, fault-affected ground conditions with heavy water inflows. The main objective of this study was to document events that took place during Tunnel F excavation and collate geological and geotechnical data related to the excavation, to aid future tunnel designers and contractors to assess the risk involved with such tunnelling projects. Data relevant to Tunnel F was collected from many personnel involved with the excavation, and from the Hong Kong Geological Survey (HKGS) of the Geotechnical Engineering Office. Geological maps, ground investigation data, tunnel mapping records, ground water inflow records and grouting records were reviewed and used to summarise the ground conditions and to analyse various potential relationships. Knowledge of ground conditions is the most important requirement for any tunnelling project. This dissertation addresses the differences between actual and predicted ground conditions and the consequences of lack of ground investigation data. The major difference between predicted and observed ground conditions during Tunnel F excavation was the amount of water ingress into the tunnel. Hundreds of liters per minute of water at up to 13bar pressure was encountered from a few probe and grout holes. In the Tolo Channel Fault area, low Q values and very high ground water inflows were experienced, and heavy temporary support and large grout volumes were required to complete the tunnel. / published_or_final_version / Applied Geosciences / Master / Master of Science

The leading cause of death for 15-20 year olds in the United States is unintentional injury. For this population, these injuries are often caused by motor vehicle accidents, alcohol and/or drug use, or a combination thereof. Sensation seeking is an internal drive to seek exciting and novel experiences. Congruous with normative developmental processes, adolescents are more likely to have a higher psycho-physiological drive towards sensation seeking than are younger children or adults. High sensation seeking is one of the risk factors for alcohol, tobacco, and other drug (ATOD) use. Other risk factors include: lack of adult-supervised time, high negative affect, and favorable attitudes and subjective norms regarding ATOD use. Sport participation addresses many of these risk factors. Sport and extracurricular activity participation have been examined in relation to ATOD use. However, the relationship between sport and ATOD use remains somewhat equivocal. This study aimed to determine the direction of the relationship between sport participation and ATOD use, and to elucidate putative, psychosocial mediators and moderators. Students in health classes (n=239, average age 16.06)) from three high schools in one suburban, Central Texas school district were given an anonymous survey regarding ATOD use, extracurricular activities, affect, attitudes, sensation seeking, social support, and subjective norms. Regression, ANOVA, and path analysis were the statistical methods employed. Consistent with previous research, favorable attitudes and subjective norms towards ATODs had a strong, positive effect on ATOD use. Sport participation was examined as moderator in the relationship between sensation seeking and ATOD use. An interaction between sport and ATOD use with sensation seeking was supported by the data. However, mean sensation seeking on the Arnett Sensation Seeking Scale was low for this sample, compared with that of other adolescent samples. Mean ATOD use was lower for sport participants compared with all other students, but not compared with extracurricular activity participants. / text
