    We report here on a diagnostic tool for improving doctoral supervision that supervisors in training at Lund University use to develop strategies for supporting their student’s learning. The tool has been developed by combining two theoretical models, an empirically generated model of orientations to doctoral supervision (Lee, 2008) and a meta-perspective on professional learning (Dall'Alba & Sandberg, 2006), with supervision strategies that has emerged in our study of supervisors in training. In this session we will present the tool and how it has been developed in our workshops for supervisors. Such workshops are mandatory for doctoral supervisors at Lund University and are held across all eight faculties as well as within single faculties. The number of supervisors that has attended is exceeding 500. We will also demonstrate how we use the tool to help supervisors explore their supervision strategies and departmental practices for doctoral education. References Dall'Alba, G., & Sandberg, J. 2006.

    Trouble in virtual heaven : Origin and consequences of social conflict in online consumption communities

    Get PDF
    This paper analyzes social conflicts among amateur computer gamers who are playing online multiplayer games. Whereas prior research tends to focus on the passion and fun of consumption community, or negative individual consequences of gaming, our research contributes with theorization of the role of social conflicts within and across gaming communities. The empirical data consists of two data collecting phases. We develop our understanding of gaming communities and culture through virtual ethnography and netnography. Then we conduct interviews with young adult gamers who belong to six communities. Our findings show four types of social conflicts; those between casual versus competitive logics, depending on skills and power, immoral behavior, and troubles of team alignment, which are related to routinized, prerogative or transgressive conflict cultures. We discuss how the study contributes with new knowledge on consumption mediated social conflicts and suggest a model of the relationship between conflict cultures, conflict types and implications.publishedVersio

    Efecto de tres bioestimulantes sobre la producción de caña de azúcar (Saccharum spp), diagnóstico y servicios realizados en área de campo Ingenio Magdalena, administración El Chaparral, Escuintla, Guatemala, C.A.

    La investigación se realizó en el Ingenio Magdalena, Escuintla, Guatemala. El Ingenio Magdalena es uno de los máximos productores de caña de azúcar en Guatemala, por eso es fundamental la condición de sus fincas en la actualidad, para saber si están realizando bien sus conocimientos en el campo, en el capítulo I está integrado por el diagnóstico en donde se reconocieron las fincas que tiene a cargo la administración, sus labores y como lo ejecuta su personal, mediante el diagnóstico fue la base principal y el punto de partida para lograr entender cómo funcionan las fincas, así como la agroindustria azucarera. Una vez conociendo de una forma más profunda las fincas se hizo más fácil los procesos y la línea de trabajo con la cual se trabajó durante toda la investigación. El capítulo II, abarca la realización del trabajo de investigación, el cual consistió en el efecto de tres bioestimulantes sobre la producción de caña de azúcar (saccharum spp), una de las partes más esenciales para la producción de azúcar lo constituye el tallo ya que en éste se acumula un jugo rico en sacarosa, con el uso de diferentes bioestimulantes (Radix 35%+TB, Regnum 25 EC y Algamar Plus), sustancias que promueven el crecimiento y desarrollo de las plantas, mejorando su metabolismo, haciéndola más resistente a condiciones adversas, estrés (abiótico y biótico), plagas o enfermedades. El capituló III está enfocado en la realización de los servicios prestados al área de malezas. Estos servicios fueron distribuidos en muestreos en los lotes de la finca La Llave de la zona tres de la administración el Chaparral, Escuintla del Ingenio Magdalena. Dichos servicios fueron de utilidad para mejorar y apoyar las labores realizadas

    Branding: The Past, Present, and Future: A Study of the Evolution and Future of Branding

    Get PDF
    Branding, as any other concept, has evolved over time: from the days when sheep of one herd started to be branded to distinguish them from another herd to the current era when everything, from water and flowers to clothes and food, is branded. Throughout these times, there have been numerous theories to describe and understand the underlying nuances. This paper finds the relationships in previous literature and reveals how these theories see branding from various perspectives and how they can be integrated to form a coherent view. It is also discussed how branding and society affect each other. Based on the knowledge of how branding theories have been developed as dependent variables of each other and the society, we are able to form a better understanding of the past, the present, and the future of branding

    A national cohort study of parental socioeconomic status and non-fatal suicidal behaviour-the mediating role of school performance

    Get PDF
    Background: A link between low parental socioeconomic status and mental health problems in offspring is well established in previous research. The mechanisms that explain this link are largely unknown. The present study investigated whether school performance was a mediating and/or moderating factor in the path between parental socioeconomic status and the risk of hospital admission for non-fatal suicidal behaviour. Methods: A national cohort of 447 929 children born during 1973-1977 was followed prospectively in the National Patient Discharge Register from the end of their ninth and final year of compulsory school until 2001. Multivariate Cox proportional hazards and linear regression analyses were performed to test whether the association between parental socioeconomic status and non-fatal suicidal behaviour was mediated or moderated by school performance. Results: The results of a series of multiple regression analyses, adjusted for demographic variables, revealed that school performance was as an important mediator in the relationship between parental socioeconomic status and risk of non-fatal suicidal behaviour, accounting for 60% of the variance. The hypothesized moderation of parental socioeconomic status-non-fatal suicidal behaviour relationship by school performance was not supported. Conclusions: School performance is an important mediator through which parental socioeconomic status translates into a risk for non-fatal suicidal behaviour. Prevention efforts aimed to reduce socioeconomic inequalities in non-fatal suicidal behaviour among young people will need to consider socioeconomic inequalities in school performance

    Secular Trends on Birth Parameters, Growth, and Pubertal Timing in Girls with Turner Syndrome.

    BACKGROUND: Whether children with chromosomal disorders of growth and puberty are affected by secular trends (STs) as observed in the general population remains unanswered, but this question has relevance for expectations of spontaneous development and treatment responses. OBJECTIVES: The aim of the study was to evaluate STs in birth parameters, growth, and pubertal development in girls with Turner syndrome (TS). STUDY DESIGN: Retrospective analysis of KIGS data (Pfizer International Growth Database). We included all TS patients who entered KIGS between 1987 and 2012 and were born from 1975 to 2004, who were prepubertal and growth treatment naïve at first entry (total number: 7,219). Pretreatment height and ages at the start of treatment were compared across 5-year birth year groups, with subgroup analyses stratified by induced or spontaneous puberty start. RESULTS: We observed significant STs across the birth year groups for birth weight [+0.18 SD score (SDS), p < 0.001], pretreatment height at mean age 8 years (+0.73 SDS, p < 0.001), height at the start of growth hormone (GH) therapy (+0.38 SDS, p < 0.001) and start of puberty (+0.42 SDS, p < 0.001). Spontaneous puberty onset increased from 15 to 30% (p < 0.001). Mean age at the start of GH treatment decreased from 10.8 to 7.4 years (-3.4 years; p < 0.001), and substantial declines were seen in ages at onset of spontaneous and induced puberty (-2.0 years; p < 0.001) and menarche (-2.1 years; p < 0.001). CONCLUSION: Environmental changes leading to increased height and earlier and also more common, spontaneous puberty are applicable in TS as in normal girls. In addition, greater awareness for TS may underlie trends to earlier start of GH therapy and induction of puberty at a more physiological age
