Experiences of the foster care process in the Republic of Ireland: retrospective accounts from biological children of foster carers

This thesis examines the experiences of the biological children of foster carers. In particular it explores their experiences in relation to inclusion, consultation and decision-making. The study also examines the support and training needs of birth children in foster families. Using a qualitative methodology in-depth, semi-structured interviews were conducted with fifteen birth children of foster carers aged between 18 and 30 years. The research findings show that for the majority of birth children, fostering was overall a positive experience which helped them develop into individuals who were caring and nonjudgemental. However, from the data collected in this study, it is clear that fostering also brings a range of challenges for birth children in foster families, such as managing feelings of loss, grief, jealousy and guilt when foster children leave. Birth children are reluctant to discuss these issues with their parents and often did not approach fostering social workers as they did not have a meaningful relationship in order to discuss their concerns. The findings also demonstrate that birth children undertake a lot of emotional work in supporting their parents, birth siblings and foster siblings. Despite the important role played by birth children in the fostering process, this contribution often goes unrecognised and unacknowledged by fostering professionals and agencies with birth children not included or consulted about foster care decisions that affect them. It is argued here that birth children are viewed by foster care professionals and agencies from a deficit based perspective. However, this study contends that it is not just foster parents who are involved in the foster care process, but the entire foster family. The findings of this study show that birth children are competent social actors capable of making valuable contributions to foster care decisions that affect their lives and that of their family.

Elicitation techniques for the evaluation of speech under stress: Towards a framework for use in a controlled environment

Existing work in Computer Science and Electronic Engineering demonstrates that Digital Signal Processing techniques can effectively identify the presence of stress in the speech signal. These techniques use datasets containing real or actual stress samples i.e. real-life stress such as 911 calls and so on. Studies that use simulated or laboratory-induced stress have been less successful and inconsistent. Pervasive, ubiquitous computing is increasingly moving towards voice-activated and voice-controlled systems and devices. Speech recognition and speaker identification algorithms will have to improve and take emotional speech into account. Modelling the influence of stress on speech and voice is of interest to researchers from many different disciplines including security, telecommunications, psychology, speech science, forensics and Human Computer Interaction (HCI). The aim of this work is to assess the impact of moderate stress on the speech signal. In order to do this, a dataset of laboratory-induced stress is required. While attempting to build this dataset it became apparent that reliably inducing measurable stress in a controlled environment, when speech is a requirement, is a challenging task. This work focuses on the use of a variety of stressors to elicit a stress response during tasks that involve speech content. Biosignal analysis (commercial Brain Computer Interfaces, eye tracking and skin resistance) is used to verify and quantify the stress response, if any. This thesis explains the basis of the author’s hypotheses on the elicitation of affectively-toned speech and presents the results of several studies carried out throughout the PhD research period. These results show that the elicitation of stress, particularly the induction of affectively-toned speech, is not a simple matter and that many modulating factors influence the stress response process. A model is proposed to reflect the author’s hypothesis on the emotional response pathways relating to the elicitation of stress with a required speech content. Finally the author provides guidelines and recommendations for future research on speech under stress. Further research paths are identified and a roadmap for future research in this area is defined.
