Allegations of child sexual abuse in Family Court cases have gained increasing attention. The study investigates factors involved in Family Court cases involving allegations of child sexual abuse. A qualitative methodology was employed to examine Records of Judgement and Psychiatric Reports for 20 cases distilled from the data corpus of 102 cases. A seven-stage methodology was developed utilising a thematic analysis process informed by principles of grounded theory and phenomenology. The explication of eight thematic clusters was undertaken. The findings point to complex issues and dynamics in which child sexual abuse allegations have been raised. The alleging parent’s allegations of sexual abuse against their ex-partner may be: the expression of unconscious deep fears for their children’s welfare, or an action to meet their needs for personal affirmation in the context of the painful upheaval of a relationship break-up. Implications of the findings are discussed.

Emergence has the potential to effect complex, creative or open-ended interactions and novel game-play. We report on research into an emergent interactive system. This investigates emergent user behaviors and experience through the creation and evaluation of an interactive system. The system is +-NOW, an augmented reality, tangible, interactive art system. The paper briefly describes the qualities of emergence and +-NOW before focusing on its evaluation. This was a qualitative study with 30 participants conducted in context. Data analysis followed Grounded Theory Methods. Coding schemes, induced from data and external literature are presented. Findings show that emergence occurred in over half of the participants. The nature of these emergent behaviors is discussed along with examples from the data. Other findings indicate that participants found interaction with the work satisfactory. Design strategies for facilitating satisfactory experience despite the often unpredictable character of emergence, are briefly reviewed and potential application areas for emergence are discussed.

Australian men’s health status is poor, with a lower life expectancy than women and higher chronic disease risk due in part to poorer dietary habits. Previous studies and sociological theories have: - linked gender norms around food and masculine ideals to men’s eating patterns; and - aligned these forms of masculinity with certain occupations. This study sought to explore the drivers of young, Australian men’s diets, the link to ideas of masculinity and occupation groups to assist in the development of strategies to support healthier eating habits in this population.

Eat Well Queensland 2002-2012: Smart Eating for a Healthier State (EWQ) was developed by the Queensland Public Health Forum in 2002 as a 10-year strategy to improve the health of Queenslanders through better food and nutrition. This study aimed to evaluate the implementation of EWQ and identify future strategic action required. Queensland Health funded a mid-point review of EWQ in 2008, to identify achievements, gaps, barriers and emerging issues associated with EWQ. 31 key stakeholders were interviewed, 83 stakeholders responded to an online survey, 150 stakeholders attended a state-wide practitioner workshop and 209 EWQ-related project reports were assessed.

Despite the prominent use of the Suchey-Brooks (S-B) method of age estimation in forensic anthropological practice, it is subject to intrinsic limitations, with reports of differential inter-population error rates between geographical locations. This study assessed the accuracy of the S-B method to a contemporary adult population in Queensland, Australia and provides robust age parameters calibrated for our population. Three-dimensional surface reconstructions were generated from computed tomography scans of the pubic symphysis of male and female Caucasian individuals aged 15–70 years (n = 195) in Amira® and Rapidform®. Error was analyzed on the basis of bias, inaccuracy and percentage correct classification for left and right symphyseal surfaces. Application of transition analysis and Chi-square statistics demonstrated 63.9% and 69.7% correct age classification associated with the left symphyseal surface of Australian males and females, respectively, using the S-B method. Using Bayesian statistics, probability density distributions for each S-B phase were calculated, providing refined age parameters for our population. Mean inaccuracies of 6.77 (±2.76) and 8.28 (±4.41) years were reported for the left surfaces of males and females, respectively; with positive biases for younger individuals (<55 years) and negative biases in older individuals. Significant sexual dimorphism in the application of the S-B method was observed; and asymmetry in phase classification of the pubic symphysis was a frequent phenomenon. These results recommend that the S-B method should be applied with caution in medico-legal death investigations of Queensland skeletal remains and warrant further investigation of reliable age estimation techniques.

What is it like to have a medical condition that few people have ever heard about? How does it feel to have to question whether daily physical activities are dangerous for you, whilst you watch your friends enjoy those activities without a care? Can you imagine that you need to have a complicated heart surgery, with risks such as paralysis or death? Or even imagine facing the painful recovery period and scars after such a surgery? Then imagine that you are a child or teenager dealing with this medical condition when all your friends are simply occupied with school and normal life. Now consider that surgery has been undertaken to extend your lifespan, but the operation is so new that the long-term outcomes are just not known? All you really know is that you might have ‘surgical repairs’ to your heart and symptoms may be relieved or managed by medications or cardiac devices, but you are never going to be cured. What if you had already experienced painful, frightening, lonely and tedious hospitalisations and you were forced to put your life on hold to re-enter that situation, time and time again. This may be your life, as a Congenital Heart Disease or CHD patient. How do such patients cope and in many cases even thrive? This chapter will review current international literature regarding the medical and personal impact of CHD. Our qualitative study of the perspectives of young CHD patients and their parents contributes to the Australian story of CHD, as well as highlighting the potential for CHD related adversity to promote personal development.

Background: End-of-life care is a significant component of work in intensive care. Limited research has been undertaken on the provision of end-of-life care by nurses in the intensive care setting. The purpose of this study was to explore the end-of-life care beliefs and practices of intensive care nurses. Methods: A descriptive exploratory qualitative research approach was used to invite a convenience sample of five intensive care nurses from one hospital to participate in a semi-structured interview. Interview transcripts were analysed using an inductive coding approach. Findings: Three major categories emerged from analysis of the interviews: beliefs about end-of-life care, end-of-life care in the intensive care context and facilitating end-of-life care. The first two categories incorporated factors contributing to the end-of-life care experiences and practices of intensive care nurses. The third category captured the nurses’ end-of-life care practices. Conclusions: Despite the uncertainty and ambiguity surrounding end-of-life care in this practice context, the intensive care setting presents unique opportunities for nurses to facilitate positive end-of-life experiences and nurses valued their participation in the provision of end-of-life care. Care of the family was at the core of nurses’ end-of-life care work and nurses play a pivotal role in supporting the patient and their family to have positive and meaningful experiences at the end-of-life.Variation in personal beliefs and organisational support may influence nurses’ experiences and the care provided to patients and their families. Strategies to promote an organisational culture supportive of quality end-of-life care practices, and to mentor and support nurses in the provision of this care are needed.

Nurse researchers are increasingly adopting qualitative methodologies for research practice and theory development. These approaches to research are, in many cases, more appropriate for the field of nursing inquiry than the previously dominant techno-rational methods. However, there remains the issue of adapting methodologies developed in other academic disciplines to the nursing research context. This paper draws upon my own experience with interpretive research to raise questions about the issue of nursing research within a social science research framework. The paper argues that by integrating the characteristics of nursing practice with the characteristics of research practice, the researcher can develop a 'nursing lens', an approach to qualitative research that brings an added dimension to social science methodologies in the nursing research context. Attention is drawn to the unique nature of the nurse-patient relationship, and the ways in which this aspect of nursing practice can enhance nursing research. Examples are given from interview transcripts to support this position.

Spatio-Temporal interest points are the most popular feature representation in the field of action recognition. A variety of methods have been proposed to detect and describe local patches in video with several techniques reporting state of the art performance for action recognition. However, the reported results are obtained under different experimental settings with different datasets, making it difficult to compare the various approaches. As a result of this, we seek to comprehensively evaluate state of the art spatio- temporal features under a common evaluation framework with popular benchmark datasets (KTH, Weizmann) and more challenging datasets such as Hollywood2. The purpose of this work is to provide guidance for researchers, when selecting features for different applications with different environmental conditions. In this work we evaluate four popular descriptors (HOG, HOF, HOG/HOF, HOG3D) using a popular bag of visual features representation, and Support Vector Machines (SVM)for classification. Moreover, we provide an in-depth analysis of local feature descriptors and optimize the codebook sizes for different datasets with different descriptors. In this paper, we demonstrate that motion based features offer better performance than those that rely solely on spatial information, while features that combine both types of data are more consistent across a variety of conditions, but typically require a larger codebook for optimal performance.

Background: Ankle fractures are one of the more commonly occurring forms of trauma managed by orthopaedic teams worldwide. The impacts of these injuries are not restricted to pain and disability caused at the time of the incident, but may also result in long term physical, psychological, and social consequences. There are currently no ankle fracture specific patient-reported outcome measures with a robust content foundation. This investigation aimed to develop a thematic conceptual framework of life impacts following ankle fracture from the experiences of people who have suffered ankle fractures as well as the health professionals who treat them. Methods: A qualitative investigation was undertaken using in-depth semi-structured interviews with people (n=12) who had previously sustained an ankle fracture (patients) and health professionals (n=6) that treat people with ankle fractures. Interviews were audio-recorded and transcribed. Each phrase was individually coded and grouped in categories and aligned under emerging themes by two independent researchers. Results: Saturation occurred after 10 in-depth patient interviews. Time since injury for patients ranged from 6 weeks to more than 2 years. Experience of health professionals ranged from 1 year to 16 years working with people with ankle fractures. Health professionals included an Orthopaedic surgeon (1), physiotherapists (3), a podiatrist (1) and an occupational therapist (1). The emerging framework derived from patient data included eight themes (Physical, Psychological, Daily Living, Social, Occupational and Domestic, Financial, Aesthetic and Medication Taking). Health professional responses did not reveal any additional themes, but tended to focus on physical and occupational themes. Conclusions: The nature of life impact following ankle fractures can extend beyond short term pain and discomfort into many areas of life. The findings from this research have provided an empirically derived framework from which a condition-specific patient-reported outcome measure can be developed.

Background Dieting has historically been the main behavioural treatment paradigm for overweight/obesity, although a non-dieting paradigm has more recently emerged based on the criticisms of the original dieting approach. There is a dearth of research contrasting why these approaches are adopted. To address this, we conducted a qualitative investigation into the determinants of dieting and non-dieting approaches based on the perspectives and experiences of overweight/obese Australian adults. Methods Grounded theory was used inductively to generate a model of themes contrasting the determinants of dieting and non-dieting approaches based on the perspectives of 21 overweight/obese adults. Data was collected using semi-structured interviews to elicit in-depth individual experiences and perspectives. Results Several categories emerged which distinguished between the adoption of a dieting or non-dieting approach. These categories included the focus of each approach (weight/image or lifestyle/health behaviours); internal or external attributions about dieting failure; attitudes towards established diets, and personal autonomy. Personal autonomy was also influenced by another category; the perceived knowledge and self-efficacy about each approach, with adults more likely to choose an approach they knew more about and were confident in implementing. The time perspective of change (short or long-term) and the perceived identity of the person (fat/dieter or healthy person) also emerged as determinants of dieting or non-dieting approaches respectively. Conclusions The model of determinants elicited from this study assists in understanding why dieting and non-dieting approaches are adopted, from the perspectives and experiences of overweight/obese adults. Understanding this decision-making process can assist clinicians and public health researchers to design and tailor dieting and non-dieting interventions to population subgroups that have preferences and characteristics suitable for each approach.

Systematic studies that evaluate the quality of decision-making processes are relatively rare. Using the literature on decision quality, this research develops a framework to assess the quality of decision-making processes for resolving boundary conflicts in the Philippines. The evaluation framework breaks down the decision-making process into three components (the decision procedure, the decision method, and the decision unit) and is applied to two ex-post (one resolved and one unresolved) and one ex-ante cases. The evaluation results from the resolved and the unresolved cases show that the choice of decision method plays a minor role in resolving boundary conflicts whereas the choice of decision procedure is more influential. In the end, a decision unit can choose a simple method to resolve the conflict. The ex-ante case presents a follow-up intended to resolve the unresolved case for a changing decision-making process in which the associated decision unit plans to apply the spatial multi criteria evaluation (SMCE) tool as a decision method. The evaluation results from the ex-ante case confirm that the SMCE has the potential to enhance the decision quality because: a) it provides high quality as a decision method in this changing process, and b) the weaknesses associated with the decision unit and the decision procedure of the unresolved case were found to be eliminated in this process.
