Automatic Identification of Large Fragments in a Pile of Broken Rock Using a Time-of-Flight Camera

This paper presents a solution to part of the problem of making robotic or semi-robotic digging equipment less dependant on human supervision. A method is described for identifying rocks of a certain size that may affect digging efficiency or require special handling. The process involves three main steps. First, by using range and intensity data from a time-of-flight (TOF) camera, a feature descriptor is used to rank points and separate regions surrounding high scoring points. This allows a wide range of rocks to be recognized because features can represent a whole or just part of a rock. Second, these points are filtered to extract only points thought to belong to the large object. Finally, a check is carried out to verify that the resultant point cloud actually represents a rock. Results are presented from field testing on piles of fragmented rock. Note to Practitioners—This paper presents an algorithm to identify large boulders in a pile of broken rock as a step towards an autonomous mining dig planner. In mining, piles of broken rock can contain large fragments that may need to be specially handled. To assess rock piles for excavation, we make use of a TOF camera that does not rely on external lighting to generate a point cloud of the rock pile. We then segment large boulders from its surface by using a novel feature descriptor and distinguish between real and false boulder candidates. Preliminary field experiments show promising results with the algorithm performing nearly as well as human test subjects.

Working with people affected by cancer – Phase 1 of a mixed methods exploration of practitioner perspectives in nutritional therapy

Introduction - Nutritional therapy (NT) is a bioscience-based branch of complementary and alternative medicine (CAM) with National Occupational Standards (NOS) and accredited training courses which include compulsory clinical training. Approximately 900 practitioners are registered with the voluntary regulator, the Complementary and Natural Healthcare Council (CNHC), but the number of unregulated practitioners is unknown. Cancer is a leading cause of death worldwide; nutrition and lifestyle factors may affect recurrence and survival rates. Many cancer patients and survivors seek individualised advice on diet and use of supplements and appropriately skilled nutritional therapy practitioners (NTP) may be well-placed to safely provide this advice. Little is known of NTPs’ perspectives on working with people affected by cancer; this study seeks to explore their views on training, use of evidence and other resources, to support the development of safe evidence-based practice in this important clinical area. Methods – An on-line anonymised questionnaire collected data from participants recruited from all UK registered NTPs. Recruitment was facilitated by the British Association for Applied Nutrition and Nutritional Therapy (BANT). Quantitative data on practitioner characteristics, years in practice, other therapies practiced and work with cancer clients were collected. Qualitative data on types of evidence used, barriers to practice and perceived training and support needs when working with clients with cancer, were collected and analysed. SPSS was used to produce descriptive statistics. Preliminary Results – 274/888 (31%) of registered NTPs participated. 61% respondents had accredited NT qualifications of which 46% were at degree or post-graduate level. 73% (202) participants indicated they also had other higher education qualifications, including 153 (56%) at degree or above. When asked to describe their position on cancer work, 17% respondents (40/238) indicated no interest, and 35% (84/238) respondents already work with cancer clients (cancer practitioners - CP). A further 48% (114/238) respondents expressed interest in starting cancer work, and typically requested specialist training and practice guidelines to support this area of clinical practice. Cancer practitioners (CP) rated searches of peer-reviewed literature as most useful for information to support practice, whereas commercial product information was rated least useful. CPs requested engagement with mainstream medicine, more access to research evidence and professional recognition to facilitate and support work with cancer clients. A need for professional networking, mentorship and/or supervision was noted by CP and non-CP respondents, which is of interest since 81% all participants worked as sole practitioners exclusively or as part of their practice, <1% worked within the NHS. Discussion & Conclusions – This is the first detailed documentation of NTP perspectives on cancer work. A number of areas have been identified for further detailed evidence to be collected using focus groups and interviews, including detailed training needs, communication with mainstream cancer professionals, access to research evidence, and professional recognition. This work will inform and support the development of professional practice guidelines for NT and inform the development of specialist training and other resources.

Doctoral Supervisor: Coach, Mentor or Master? Developing an Alternative Paradigm for Doctoral Supervision

This working paper is the second in a series of working papers presenting the on-going findings from a longitudinal research project grounded in exploring the experience of doctoral supervision and developing practice. In the first paper and phase one of this research study, Cook, Nichol and Loon (2014) explored the existing context for doctoral supervision and, drawing from literature on the problematic nature of doctoral supervision and coaching and mentoring, considered the value of drawing on coaching and mentoring models in formulating alternative paradigms for doctoral supervision. This paper reports the findings of phase one, a mixed methods study of experiences of doctoral supervision with supervisors and students in one UK university business school, from which the Collaborative Action Doctoral Supervision conceptual model emerged. The paper also introduces phase two, a collaborative action research study with doctoral supervisors and students who are applying, reflecting on and developing further this doctoral supervision model. We are aiming to answer the question of whether the use of coaching and mentoring in doctoral supervision enables the transfer and sustainability of learning from the doctoral supervision session to outside the experience and improves the quality. Is the doctoral supervisor coach, mentor or master? Key words Doctoral supervision, coaching, mentoring, collaborative action research.

Public Protection? The Implication of Grayling's 'Transforming Rehabilitation' Agenda on the Safety of Women and Children

Abstract The Coalition Government's new Transforming Rehabilitation (TR) agenda jeopardises the work undertaken with perpetrators of domestic abuse by highly skilled, qualified probation staff. Under new changes outlined by Grayling, Lord Chancellor and Secretary of State for Justice, probation clients who are assessed as posing a medium/low risk of causing harm will be assigned to private sector/voluntary organisations rather than come under the remit of the National Probation Service. This article argues that victims of domestic abuse, primarily women and children, will be placed at an increased risk of harm given this latest TR strategy. The majority of domestic abuse cases will be assessed as posing a medium risk of causing harm and will receive lower levels of intervention by a variety of disparate agencies and organisations. The Ministry of Justice states that the National Probation Service will directly manage offenders who pose a high risk of serious harm to the public, this article will argue that all perpetrators of domestic abuse should be considered as an important exception to this stance, and should remain under the auspices of Probation supervision, irrespective of statistical risk assessment, as has sex offender case management and sex offender treatment programme delivery.

A Comparison of Audio Recordings and Therapist's Process Notes in Child and Adolescent Psychoanalytic Psychotherapy

Therapistsʼ process notes - written descriptions of a session produced shortly afterwards from memory - hold a significant role in child and adolescent psychoanalytic psychotherapy. They are central in training, in supervision, and in developing oneʼs understanding through selfsupervision and forms of psychotherapy research. This thesis examines such process notes through a comparison with audio recordings of the same sessions. In so doing, it aims to generate theory that might illuminate the causes of significantly patterned discrepancies between the notes and recordings, in order to understand more about the processes at work in psychoanalytic psychotherapy and to explore the nature of process notes, their values and limitations. The literature searches conducted revealed limited relevant studies. All identified studies that compare process notes with recordings of sessions seek to quantify the differences between the two forms of recording. Unlike these, this thesis explores the meaning of the differences between process notes and recordings through qualitative data analysis. Using psychoanalytically informed grounded theory, in total nine sets of process notes and recordings from three different psychoanalytic psychotherapists are analysed. The analysis identifies eight core categories of findings. Initial theories are developed from these categories, most significantly concerning the role and influence of a ʻcore transference dynamicʼ between therapist and patient. Further theory is developed on the nature and function of process notes as a means for the therapistʼs conscious and unconscious processing of the session, as well as on the nature of the influence of the relationships – both internal and external – within which they are written. In the light of the findings, a proposal is made for a new approach for learning about the patient and clinical work, ʻthe comparison methodʼ (supervision involving a comparison of process notes and recordings), and, in particular, for its inclusion within the training of psychoanalytic psychotherapists. Further recommendations for research are also made.

Self-Harm in Secondary Schools: What are the Perceptions and Experiences of Staff ?

The purpose of this study is to explore the perceptions and experiences of secondary school staff with regard to adolescent self-harm. The research was conducted in a Local Authority where there were particular concerns about rising numbers of young people presenting with self-harm. While the majority of young people who self-harm are supported in the community and never access clinical services, surprisingly little research has considered the role of schools and their staff. The research that has been done suggests that school staff can feel underqualified and overwhelmed in their attempts to support young people who self-harm. Further, there is a growing evidence base that when young people experience negative attitudes towards self-harm it is distressing and reduces the chance of them seeking further help. To address this, qualitative exploratory research was conducted with thirteen members of staff working in secondary schools. Since the research was concerned not just with experiences, but also with perceptions of adolescent self-harm, the participants were from two groups: those with direct experience of supporting young people who have self-harmed and those without any direct experience. Data collection involved individual semi-structured interviews which were analysed using thematic analysis. The research indicated that secondary school staff are keen to help and understand young people who self-harm, but that they do not always feel skilled or confident enough to do so, often feeling that some kind of specialist is required and/or fearing that they might make a situation worse. Findings highlighted the emotional impact of this work and illustrated the importance of supporting staff, who expressed a desire for further training and other forms of professional support such as supervision.

Supervision For School Staff: What is Valuable about Solution Circles?

Group supervision is used for support, education and/or monitoring. Despite the potential value of these elements for school staff, it is rarely practised. This mixed methods research, from a critical realist perspective, explored the use of Solution Circles to structure staff supervision groups in three schools. Five circles were run in each school, involving thirty-one participants, eighteen of whom contributed data. Thirteen staff trained as facilitators. The self-efficacy, resilience and anxiety levels of the staff taking part were not found to be significantly different as a result of the intervention. However, a small effect size was noted for self-efficacy, perhaps worthy of further investigation in the context of the small sample size. Thematic analysis of participant feedback (gathered during the last circle, which ran as a Focus Group) indicated the following mechanisms as affecting the value of Solution Circles for staff supervision groups: the structure of the sessions; aspects linked to the groups meeting a ‘need to talk’; elements which helped participants to ‘feel like a team’; and, school context factors. Semi-structured interview data from six facilitators indicated that the structure of the circles, individual characteristics of facilitators, the provision of support for facilitators, and elements of the wider school context, were all mechanisms which affected the facilitation of the programme. Further research might implement elements of these mechanisms and measure their impact.

The Multi-Faceted Experience of Empathy in Intellectual Disability Settings: An IPA Study

This research thesis explored the concept of empathy. The specific purpose was to further understand the idea of empathy in relation to the experience of male support workers who provide residential care to adults with intellectual disabilities (ID) and challenging behaviour. The thesis aimed to provide some insights into how support workers develop and extract meaning from their experiences of relationships with clients and the impact of this on their own self-care, namely, self-compassion. Since personal accounts of experience were required, a qualitative methodology was employed, Interpretative Phenomenological Analysis (IPA) (Smith, 2004). This methodology was selected as it allows for the exploration and interpretation of idiographic lived experience and meaning making. 8 experienced support workers were interviewed using a semi structured interview. Four superordinate themes emerged from the data. These included: 1. Making sense of the others inner world; 2. Processes that enhance empathic practice; 3. Tensions and conflicts, and 4. Management of distressing feelings. Differing accounts of interpreting the needs of clients were identified which helped participants understand, make sense of their interpersonal experience and participate in their role. These included utilising academic knowledge and senses, particularly sight and hearing, which were seemingly complemented by a level of reflective practice. Additionally, to make sense of the experience of a client, they appeared to put themselves in their position, suggesting a form of empathy. Participants appeared to engage in a process of reflection on their relationships with clients, which helped them think about what they had learned about the person’s needs, moreover, this process enabled them to identify some of their own responses and feelings. However, participants seemed to struggle to recognise the occurrence or impact of distressing emotional experience and to express their feelings, possibly in response to a deep sense of responsibility and fear of transferring emotional distress to others. This dilemma of holding two potentially conflicting views of experience seemed to inhibit self-compassion. Although not specifically testing theories of empathy, from the overall findings, it could be suggested that empathy may be a dynamic, transient process that is influenced by reflexivity, values and context. The context in which participants discussed their practice, and situated within their accounts, suggested a sense of confusion and uncertainty. Consequently, it is suggested this impacted on how participants understood and related to clients, and to themselves. There were some specific implications for Counselling Psychology practice, mostly concerning training and supervision. These included recommendations for staff training and supervision, systemic organisational intervention, policy development, recommendations for revisions to models of specialist care frameworks and clinical training.

Online video-based resistance training improves the physical capacity of junior basketball athletes

Junior basketball athletes require a well-designed resistance training program to improve their physical development. Lack of expert supervision and resistance training in junior development pathways may be overcome by implementing an online video-based program. The aim of this study was to compare the magnitude of improvement (change) in physical performance and strength and functional movement patterns of junior basketball athletes using either a fully supervised or an online video-based resistance training program. Thirty-eight junior basketball athletes (males, n = 17; age, 14 ± 1 year; height, 1.79 ± 0.10 m; mass, 67 ± 12 kg; females, n = 21; age, 15 ± 1 year; height, 1.70 ± 0.07 m; mass, 62 ± 8 kg) were randomly assigned into a supervised resistance training group (SG, n = 13), video training group (VG, n = 13) or control group (CG, n = 12) and participated in a 6-week controlled experimental trial. Pre- and posttesting included measures of physical performance (20-m sprint, step-in vertical jump, agility, sit and reach, line drill, and Yo-Yo intermittent recovery level 1), strength (15 s push-up and pull-up), and functional movement screening (FMS). Both SG and VG achieved 3-5% ± 2-4% (mean ± 90% confidence limits) greater improvements in several physical performance measures (vertical jump height, 20-m sprint time, and Yo-Yo endurance performance) and a 28 ± 21% greater improvement in push-up strength compared with the CG. The SG attained substantially larger gains in FMS scores over both the VG (12 ± 10%) and CG (13 ± 8%). Video-based training appears to be a viable option to improve physical performance and strength in junior basketball athletes. Qualified supervision is recommended to improve functional movement patterns in junior athletes.

Clinical supervision training across contexts.

BACKGROUND: Clinicians require specific skills to teach or supervise students in the workplace; however, there are barriers to accessing faculty member development, such as time, cost and suitability. The Clinical Supervision Support Across Contexts (ClinSSAC) programme was designed to provide accessible interprofessional educator training to clinical supervisors across a wide range of clinical settings. CONTEXT: In Australia there are increasing numbers of health care students, creating pressure on existing placements. Students are now increasingly learning in community settings, where clinicians have traditionally had less access to faculty member development. INNOVATION: An interprofessional team collaborated in the development and implementation of ClinSSAC. A total of 978 clinicians participated in a face-to-face, interactive, introductory module to clinical supervision; 672 people accessed the equivalent online core module, with 23 per cent completing all activities. Additional profession-and discipline-specific modules were also developed. IMPLICATIONS: Formal project evaluation found that most participants rated the workshops as helpful or very helpful for their roles as clinical supervisors. Interdisciplinary learning from the workshops was reported to enable cross-discipline supervision. Large participant numbers and favourable ratings indicate a continuing need for basic training in education. Key factors to workshop success included expert facilitators, the interprofessional context and interactive model. The online modules were an important adjunct, and provided context-specific resources, but the low online completion rate suggests protected face-to-face time for faculty member development is still required. Programmes such as ClinSSAC have the capacity to promote interprofessional education and practice. There are barriers to accessing faculty member development, such as time, cost and suitability.

Desistance: The “other side” of change and implications for maintenance programs

How offenders cease offending and engage in the desistance process is a key consideration for effective rehabilitation. While attention is increasing on desistance and its utility in the supervision and case management of offenders postrelease, it’s yet to be integral to postrelease programs. This paper considers the implications of the desistance process for psychological postrelease programs, such as community maintenance programs. There will be a brief review of some of the theories of desistance, consideration of the interrelationship between desistance theory and community maintenance programs and discussion about the implications of desistance theory for the delivery of community maintenance programs.
