The JCMT BISTRO Survey: Multi-wavelength polarimetry of bright regions in NGC 2071 in the far-infrared/submillimetre range, with POL-2 and HAWC+
Polarized dust emission is a key tracer in the study of interstellar medium and of star formation. The observed polarization, however, is a product of magnetic field structure, dust grain properties and grain alignment efficiency, as well as their variations in the line of sight, making it difficult to interpret polarization unambiguously. The comparison of polarimetry at multiple wavelengths is a possible way of mitigating this problem. We use data from HAWC+/SOFIA and from SCUBA-2/POL-2 (from the BISTRO survey) to analyse the NGC 2071 molecular cloud at 154, 214 and 850 μm. The polarization angle changes significantly with wavelength over part of NGC 2071, suggesting a change in magnetic field morphology on the line of sight as each wavelength best traces different dust populations. Other possible explanations are the existence of more than one polarization mechanism in the cloud or scattering from very large grains. The observed change of polarization fraction with wavelength, and the 214-to-154 μm polarization ratio in particular, are difficult to reproduce with current dust models under the assumption of uniform alignment efficiency. We also show that the standard procedure of using monochromatic intensity as a proxy for column density may produce spurious results at HAWC+ wavelengths. Using both long-wavelength (POL-2, 850 μm) and short-wavelength (HAWC+, ≲200μm) polarimetry is key in obtaining these results. This study clearly shows the importance of multi-wavelength polarimetry at submillimeter bands to understand the dust properties of molecular clouds and the relationship between magnetic field and star formation
The applied psychology of addictive orientations : studies in a 12-step treatment context.
The clinical data for the studies was collected at The PROMIS Recovery Centre, a Minnesota Model treatmentc entre for addictions,w hich encouragesth e membership and use of the 12 step Anonymous Fellowships, and is abstinence based. The area of addiction is contextualised in a review chapter which focuses on research relating to the phenomenon of cross addiction. A study examining the concept of "addictive orientations" in male and female addicts is described, which develops a study conductedb y StephensonM, aggi, Lefever, & Morojele (1995). This presents study found a four factor solution which appeared to be subdivisions of the previously found Hedonism and Nurturance factors. Self orientated nurturance (both food dimensions, shopping and caffeine), Other orientated nurturance (both compulsive helping dimensions and work), Sensation seeking hedonism (Drugs, prescription drugs, nicotine and marginally alcohol), and Power related hedonism (Both relationship dimensions, sex and gambling. This concept of "addictive orientations" is further explored in a non-clinical population, where again a four factor solution was found, very similar to that in the clinical population. This was thought to indicate that in terms of addictive orientation a pattern already exists in this non-clinical population and that consideration should be given to why this is the case. These orientations are examined in terms of gender differences. It is suggested that the differences between genders reflect power-related role relationships between the sexes. In order to further elaborate the significance and meaning behind these orientations, the next two chapters look at the contribution of personality variables and how addictive orientations relate to psychiatric symptomatology. Personality variables were differentially, and to a considerable extent predictably involved with the four factors for both males and females.Conscientiousness as positively associated with "Other orientated Nurturance" and negatively associated with "Sensation seeking hedonism" (particularly for men). Neuroticism had a particularly strong association with the "Self orientated Nurturance" factor in the female population. More than twice the symptomatology variance was explained by the factor scores for females than it was for males. The most important factorial predictors for psychiatric symptomatology were the "Power related hedonism" factor for males, and "Self oriented nurturance" for females. The results are discussed from theoretical and treatment perspectives
Studies of strategic performance management for classical organizations theory & practice
Nowadays, the activities of "Performance Management" have spread very broadly in actually every part of business and management. There are numerous practitioners and researchers from very different disciplines, who are involved in exploring the different contents of performance management. In this thesis, some relevant historic developments in performance management are first reviewed. This includes various theories and frameworks of performance management. Then several management science techniques are developed for assessing performance management, including new methods in Data Envelopment Analysis (DEA) and Soft System Methodology (SSM). A theoretical framework for performance management and its practical procedures (five phases) are developed for "classic" organizations using soft system thinking, and the relationship with the existing theories are explored. Eventually these results are applied in three case studies to verify our theoretical development. One of the main contributions of this work is to point out, and to systematically explore the basic idea that the effective forms and structures of performance management for an organization are likely to depend greatly on the organizational configuration, in order to coordinate well with other management activities in the organization, which has seemingly been neglected in the existing literature of performance management research in the sense that there exists little known research that associated particular forms of performance management with the explicit assumptions of organizational configuration. By applying SSM, this thesis logically derives some main functional blocks of performance management in 'classic' organizations and clarifies the relationships between performance management and other management activities. Furthermore, it develops some new tools and procedures, which can hierarchically decompose organizational strategies and produce a practical model of specific implementation steps for "classic" organizations. Our approach integrates popular types of performance management models. Last but not least, this thesis presents findings from three major cases, which are quite different organizations in terms of management styles, ownership, and operating environment, to illustrate the fliexbility of the developed theoretical framework

Conflict and climate factors and the risk of child acute malnutrition among children aged 24–59 months: a comparative analysis of Kenya, Nigeria, and Uganda
Acute malnutrition affects a sizeable number of young children around the world, with serious repercussions for mortality and morbidity. Among the top priorities in addressing this problem are to anticipate which children tend to be susceptible and where and when crises of high prevalence rates would be likely to arise. In this article, we highlight the potential role of conflict and climate conditions as risk factors for acute malnutrition, while also assessing other vulnerabilities at the individual- and household-levels. Existing research reflects these features selectively, whereas we incorporate all the features into the same study. The empirical analysis relies on integration of health, conflict, and environmental data at multiple scales of observation to focuses on how local conflict and climate factors relate to an individual child’s health. The centerpiece of the analysis is data from the Demographic and Health Surveys conducted in several different cross-sectional waves covering 2003–2016 in Kenya, Nigeria, and Uganda. The results obtained from multi-level statistical models indicate that in Kenya and Nigeria, conflict is associated with lower weight-for-height scores among children, even after accounting for individual-level and climate factors. In Nigeria and Kenya, conflict lagged 1–3 months and occurring within the growing season tends to reduce WHZ scores. In Uganda, however, weight-for-height scores are primarily associated with individual-level and household-level conditions and demonstrate little association with conflict or climate factors. The findings are valuable to guide humanitarian policymakers and practitioners in effective and efficient targeting of attention, interventions, and resources that lessen burdens of acute malnutrition in countries prone to conflict and climate shocks
Los géneros discursivos prototípicos de la Licenciatura en Administración de Empresas : conformación de un corpus textual con fines pedagógicos
Especialización en Didáctica de la Lenguas ExtranjerasEn el contexto de enseñanza de lectura comprensiva en lengua extranjera en el nivel superior,
la selección textual para conformar un corpus pedagógico representa un aspecto fundamental,
dado que este constituye la base de los materiales didácticos con los que se organiza la
enseñanza (Hurtado Albir, 2011). En este sentido, dicho corpus debería incluir géneros
prototípicos de las comunidades disciplinares (Bhatia, 1993; Cassany, 2008; Hyland, 2002)
sobre temáticas de interés para los estudiantes atendiendo también a la opinión de los
especialistas del área disciplinar. El presente trabajo aborda la problemática del diseño de
materiales de comprensión lectora en inglés en el ámbito universitario. En cuanto al propósito
principal, este estudio procura contribuir al mejoramiento de las prácticas pedagógicas en dicho
contexto, a través de la descripción de los géneros y temáticas afines a la disciplina para la
conformación del corpus pedagógico del nuevo manual para Lengua Inglesa II de la
Licenciatura en Administración de Empresas, UCC. La problemática planteada es abordada
desde un enfoque teórico que articula el concepto de lectura comprensiva en el nivel superior y
los aportes de la teoría del género, según la Escuela de Inglés con Fines Específicos, y de la
lingüística textual de base germánica. La presente investigación de alcance descriptivo y con
un enfoque predominantemente cualitativo se desarrolló entre el segundo semestre de 2018 y
el primer semestre de 2019. El proceso metodológico se organizó en torno a tres instrumentos
clave para la recolección de datos, a saber, la ficha bibliográfica, el cuestionario a estudiantes
y el cuestionario a docentes. A su vez, la información recolectada a partir de estas herramientas
permitió realizar la selección textual y el consiguiente análisis multinivel de los textos del
corpus. Los resultados obtenidos han permitido sugerir no solo una propuesta de corpus
ejemplar con fines pedagógicos para el contexto educativo mencionado, sino también algunos
posibles lineamientos que podrían considerarse para conducir una futura ampliación del corpus

School Reintegration Following Hospital Treatment for an Eating Disorder; Two Case Studies with Multiple Perspectives on the Reintegration Process
School reintegration following hospitalisation has been explored for children and young people (CYP) with medical and mental health needs. No previous research was identified that specifically focused on the experiences of CYP who have returned to school following inpatient care for an eating disorder. A multiple case study design was used to retrospectively explore the experiences of two young people who successfully reintegrated to school following hospital support for an eating disorder. The study compromised of two case studies. The research focused on exploring ‘what went well’ and ‘what could have been even better’ during the school reintegration process.
Semi-structured interviews were used in two case studies of a young person who had spent time at inpatient unit for over 6 months for support with anorexia nervosa before reintegrating into sixth form. Views were gathered from four participants in each case study: the young person, their parent, the young person's previous hospital school key teacher and the home school key person (who supported with the reintegration). The interviews were carried out remotely, via Microsoft Teams, due to the coronavirus pandemic. The dataset from each case study was analysed separately using thematic analysis and an overall thematic map was presented for the findings from each case study.
Three themes were identified in Case Study One: young person’s strengths, preparation for young person’s return and supportive relationships and environment. Four themes were identified in Case Study Two: young person’s internal motivators and external motivators, preparing for school return, support systems, and sense of school belonging and connectedness. Findings are discussed in relation to previous research that has explored school reintegration following hospital support for mental health difficulties more broadly and psychological theory. Strengths, limitations and implications for schools, families and educational psychologists are highlighted. Recommendations for future research are also discussed
The Lived Experiences of Yoga Practice for Female Survivors of Child Sexual Abuse: An Interpretative Phenomenological Analysis
Childhood sexual abuse (CSA) permeates all aspects of personhood including the body. There is a surge in the interest in reviewing yoga’s potential usefulness for trauma survivors in clinical trials. However, very little research focuses on women’s perspectives who experienced CSA and have subsequently practised yoga in community settings. This study investigated six women’s lived experiences of yoga practice, mainly focusing on the helpful and unhelpful aspects of yoga that mediated their recovery. Adult women survivors with experience of movement-based yoga in a group setting for at least eight weeks in the last year were recruited. Data were collected using individual, face-to-face, and semi-structured interviews. The transcribed data were analysed using Interpretative phenomenological analysis (IPA) underpinned by constructivist ontology, phenomenological epistemology, and feminist axiology. Three emergent themes were identified- “Coming to yoga”, “Process of becoming” and “Reclaiming life”. Women’s narratives in this study illustrated that they found yoga a useful and resilience-building resource in their journey of healing. With consistent and frequent practice, they reported feeling more present, self-aware, and compassionate towards themselves. Teacher’s qualities such as fostering safety, choice and holistic focus were identified as significant mediating factors that aided this journey, whereas crowded, mixed-gender, and posture-focused practice presented challenges for some respondents. This study has the potential to help Counselling psychologists (CoP), therapists, psychologists, mental health practitioners, yoga teachers, and health professionals involved in the care of the CSA survivors in implementing an evidence-based and holistic approach that facilitates self-directed recovery of CSA survivors. Further research is needed to establish if the benefits and challenges of different aspects of practice apply to the diverse population and its potential usefulness in various phases of recovery. Also, find ways to standardize the yoga practice considering variations in the approach to ensure safe and ethical practice
