The directions taken by young people on leaving compulsory education:a study in two Birmingham schools

The thesis addresses the relative importance of factors affecting working-class school-leavers' post-compulsory education transitions into post-sixteen education, training, employment and unemployment. It focuses on school-leavers choosing to enter the labour market, whether successfully or not and the influences affecting this choice. Methodologically, the longitudinal approach followed young people from before they left school to a period of months after. Discrepancies between young people's intended and actual destinations emphasised the diverse influences on post-sixteen transitions. These influences were investigated through a dynamic multi-method approach, drawing from quantitative and qualitative methodologies providing depth and insight while locating the research within a structural framework, allowing a comparison with local and national trends. Two crucial factors of school and gender affected young people's intended and actual post-sixteen directions. School policy, including treatment of disaffected pupils and recruitment to a large, on-site sixth form, influenced the number of pupils opting to continue their education. Girls were more likely to continue education after the end of compulsory schooling and gave different reasons to boys for doing so. Family and peer groups were influential, helping young people develop a 'horizon for action' incorporating habitus and subjective preferences that specified acceptable post-sixteen directions. These influences operated within the context of the local labour market. Perception of the latter rather than actual conditions informed post-sixteen decisions; however, labour market reality influenced the success of the school-leavers' endeavours. The research found that the economics-based rational choice model of decision-making did not apply to many working class school-leavers. The cohort made pragmatically rational decisions dependent on their 'horizon for action'. based on partial, occasionally inaccurate information. Policy recommendations consider the careers service and structure or school sixth forms as aiding successful transitions from compulsory education into education, employment or training. The maintenance allowance may be ineffectual in tackling its objective of social inclusion.

An advanced real-time predictive maintenance framework for large scale machine systems

This thesis introduces and develops a novel real-time predictive maintenance system to estimate the machine system parameters using the motion current signature. Recently, motion current signature analysis has been addressed as an alternative to the use of sensors for monitoring internal faults of a motor. A maintenance system based upon the analysis of motion current signature avoids the need for the implementation and maintenance of expensive motion sensing technology. By developing nonlinear dynamical analysis for motion current signature, the research described in this thesis implements a novel real-time predictive maintenance system for current and future manufacturing machine systems. A crucial concept underpinning this project is that the motion current signature contains infor­mation relating to the machine system parameters and that this information can be extracted using nonlinear mapping techniques, such as neural networks. Towards this end, a proof of con­cept procedure is performed, which substantiates this concept. A simulation model, TuneLearn, is developed to simulate the large amount of training data required by the neural network ap­proach. Statistical validation and verification of the model is performed to ascertain confidence in the simulated motion current signature. Validation experiment concludes that, although, the simulation model generates a good macro-dynamical mapping of the motion current signature, it fails to accurately map the micro-dynamical structure due to the lack of knowledge regarding performance of higher order and nonlinear factors, such as backlash and compliance. Failure of the simulation model to determine the micro-dynamical structure suggests the pres­ence of nonlinearity in the motion current signature. This motivated us to perform surrogate data testing for nonlinearity in the motion current signature. Results confirm the presence of nonlinearity in the motion current signature, thereby, motivating the use of nonlinear tech­niques for further analysis. Outcomes of the experiment show that nonlinear noise reduction combined with the linear reverse algorithm offers precise machine system parameter estimation using the motion current signature for the implementation of the real-time predictive maintenance system. Finally, a linear reverse algorithm, BJEST, is developed and applied to the motion current signature to estimate the machine system parameters.

Total productive maintenance implementation in the newspaper printing industry:an action research approach

The objective of Total Productive Maintenance (TPM) is to maximise plant and equipment effectiveness, to create a sense of ownership for operators, and promote continuous improvement through small group activities involving production, engineering and maintenance personnel. This paper describes and analyses a case study of TPM implementation at a newspaper printing house in Singapore. However, rather than adopting more conventional implementation methods such as employing consultants or through a project using external training, a unique approach was adopted based on Action Research using a spiral of cycles of planning, acting observing and reflecting. An Action Research team of company personnel was specially formed to undertake the necessary fieldwork. The team subsequently assisted with administering the resulting action plan. The main sources of maintenance and operational data were from interviews with shop floor workers, participative observation and reviews conducted with members of the team. Content analysis using appropriate statistical techniques was used to test the significance of changes in performance between the start and completion of the TPM programme. The paper identifies the characteristics associated with the Action Research method when used to implement TPM and discusses the applicability of the approach in related industries and processes.

Set-up and maintenance of syringe drivers for subcutaneous drug administration in palliative care

Focal points: Details of syringe driver use were collected from 11 inpatient hospice units in the West Midlands and compared with predetermined standards set by a multidisciplinary group We recorded 294 syringe driver events which complied with standards for the choice of administration site, protection of the syringe driver from light and the reason for initiation of the infusion Issues of nurse training, variability in prescribing practices, provision of written information for patients, labelling and documentation of the diluent used were all identified as areas in which compliance with standards could be improved
