Optimising learning in the workplace

There are three bodies of research that suggest ways in which learning in the workplace can be optimised. The first is evident in the emergent literature endorsing the need to include workplace pedagogies as useful epistemological tools for learners. It is now widely recognised that the workplace provides various pedagogies that facilitate and support learning.

Deepening our understanding about school leadership : learning from educators and non-educators

Increasingly, leadership is argued as a way forward to improve performance and practice in a variety of contexts. School leadership is no different. There is little doubt that in the current globalised world characterized by change and complexity, effective school leadership is a key requirement. The contribution of this chapter is framed around a synthesis of current research, writing and theoretical insights regarding leadership. It draws upon three bodies of writing, Firstly, it begins by distilling several key themes and trends regarding educational leadership from the current research and writing. Secondly, it reports on the findings of a current research project carried out by the authors that explored the leadership stories of ten outstanding leaders from non-educational settings in Australia. Finally, it concludes by referring to some of the paradoxes and tensions inherent in the work of school leaders. It is argued that understanding and endeavouring to reconcile these dilemmas is a pre-requisite for school leaders as they continue to operate in an environment fraught with change and complexity.

Weaving yarns : the lived experience of Indigenous Australians with adult-onset disability in Brisbane

Indigenous Australians have lower levels of health than mainstream Australians and (as far as statistics are able to indicate) higher levels of disability, yet there is little information on Indigenous social and cultural constructions of disability or the Indigenous experience of disability. This research seeks to address these gaps by using an ethnographic approach, couched within a critical medical anthropology (CMA) framework and using the “three bodies” approach, to study the lived experience of urban Indigenous people with an adult-onset disability. The research approach takes account of the debate about the legitimacy of research into Indigenous Australians, Foucault‟s governmentality, and the arguments for different models of disability. The possibility of a cultural model of disability is raised. After a series of initial interviews with contacts who were primarily service providers, more detailed ethnographic research was conducted with three Indigenous women in their homes and with four groups of Indigenous women and men at an Indigenous respite centre. The research involved multiple visits over a period extending more than two years, and the establishment of relationships with all participants. An iterative inductive approach utilising constant comparison (i.e. a form of grounded theory) was adopted, enabling the generation and testing of working hypotheses. The findings point to the lack of an Indigenous construct of disability, related to the holistic construction of health among Indigenous Australians. Shame emerges as a factor which affects the way that Indigenous Australians respond to disability, and which operates in apparent contradiction to expectations of community support. Aspects of shame relate to governmentality, suggesting that self-disciplinary mechanisms have been taken up and support the more obvious exertion of government power. A key finding is the strength of Indigenous identity above and beyond other forms of identification, e.g. as a person with a disability, expressed in forms of resistance by individuals and service providers to the categories and procedures of the mainstream. The implications of a holistic construction of health are discussed in relation to the use of CMA, the interpretation of the “three bodies”, governmentality and resistance. The explanatory value of the concept of sympatricity is discussed, as is the potential value of a cultural model of disability which takes into account the cultural politics of a defiant Indigenous identity.

The lived experience of families living with spinal cord disability in Northeast Thailand

The experience of disability in the global South remains relatively underreported in spite of the greater focus on disability as both an impediment to development and frequently as a result of development. This article reports a qualitative study using ethnographic techniques undertaken in the province of Khon Kaen in Northeast Thailand. The primary participants were men who had experienced a severe spinal cord injury at a time when they were breadwinners, a role which is significant in the context of a modernising state that is an active participant in a global economy. The experiences, constructions and beliefs of these men, their family carers, and other informants illustrate the complex ways in which social and cultural factors interact with the opportunities, challenges and constraints of transition to modernity. The findings, interpreted according to the 'three bodies' approach, illustrate the intersection of colonising effects, governmentality and resistance, and embodied experience in a cultural context.

Evaluative decision-making for high-quality professional development: Cultivating an evaluative stance

Unprecedented policy attention to early childhood education internationally has highlighted the crucial need for a skilled early years workforce. Consequently, professional development of early years educators has become a global policy imperative. At the same time, many maintain that professional development research has reached an impasse. In this paper, we offer a new approach to addressing this impasse. In contrast to calls for a redesign of comparative studies of professional development programs, or for the refinement of researcher-constructed professional development evaluation frameworks, we argue the need to cultivate what we refer to as an ‘evaluative stance’ amongst all involved in making decisions about professional development in the early years – from senior bureaucrats with responsibilities for funding professional development programs to individual educators with choices about which professional development opportunities to take up. Drawing on three bodies of literature -- evaluation capacity building, personal epistemology, and co-production -- that, for the most part, have been overlooked with respect to early years professional learning this paper proposes a conceptual framework to explain why cultivating an evaluative stance in professional development decision-making has rich possibilities for systemic, sustainable, and transformative change in early years education.

Data Visualisation Does Political Things

In this paper I advance the theory of critical communication design by exploring the politics of data, information and knowledge visualisation in three bodies of work. Data reflects power relations, special interests and ideologies that determine which data is collected, what data is used and how it is used. In a review of Max Roser’s Our World in Data, I develop the concepts of digital positivism, datawash and darkdata. Looking at the Climaps by Emaps project, I describe how knowledge visualisation can support integrated learning on complex problems and nurture relational perception. Finally, I present my own Mapping Climate Communication project and explain how I used discourse mapping to develop the concept of discursive confusion and illustrate contradictions in this politicised area. Critical approaches to information visualisation reject reductive methods in favour of more nuanced ways of presenting information that acknowledge complexity and the political dimension on issues of controversy.

Expectativas del nuevo proyecto para la reforma al sistema de salud 2013

Esta investigación se desarrolla, bajo una hipótesis, la cual se busca comprobar, analizando la evidencia encontrada en documentos Teóricos investigativos de autores expertos y especialistas en el tema y en publicaciones de la prensa nacional además de las leyes que corresponden a las dos reformas de la salud la 1122 de 2007 y la 1438 de 2011. La hipótesis planteada para esta investigación es que “mientras los nuevos planteamientos para la reforma de la salud no incluyan dentro de su propuesta una solución evidente a los principales problemas encontrados en el sistema de salud actual y no establezca un control fiscal y una regulación verdadera sobre el manejo de los fondos del sistema de salud; Los principios de universalidad, eficiencia, integralidad, libre escogencia, competencia sana y calidad no serán cumplidos y por lo tanto el pueblo Colombiano no podrá ejercer su derecho a la salud como lo plantea la Constitución Política de Colombia de 1991 y la ley 100 de 1993. Para comprobar la hipótesis se han seleccionado como documentos a analizar, tres publicaciones de la prensa nacional, cuatro de autores expertos y especializados en el tema y tres documentos adicionales que corresponden a las dos reformas realizadas al sistema de salud en los años 2007 y 2011 y a la nueva propuesta radicada por el gobierno nacional a inicios de este año. Es de suma importancia conocer las apreciaciones de los autores sobre el grupo de variables que se utilizarán para desarrollar este estudio. Estas variables pertenecen a aquellas que influencian el equilibrio financiero y que adicionalmente afectan directamente a la población impactando su bienestar y su calidad de vida. Entre esas variables se destacan (i) aspectos demográficos y de la fuerza laboral, (ii) aspectos económicos como los niveles de ingreso, salarios y empleo, (iii) cobertura del sistema de salud, (iv) calidad y acceso a los servicios del sistema, (v) duplicidad del gasto (vi) flujo de los recursos del sistema de salud (problemas institucionales), (vii) Gasto en salud y estabilidad financiera y (viii) regulación financiera. El Formato utilizado para la comparación análisis y síntesis de los documentos teóricos investigativos y de las publicaciones de la prensa nacional, consta de tres cuerpos. El primero, contiene las características relacionadas con tiempo y espacio de la publicación. El segundo, hace énfasis en el contenido y en los temas y variables de interés para el desarrollo de la investigación. Y el tercero hace énfasis en el contenido y en los temas y variables de interés para el desarrollo de la investigación. Al hacer el análisis, síntesis y comparación de estos artículos se resolverán algunos interrogantes que pueden llevarnos a comprobar la hipótesis como los son:¿Cuáles han sido los principales logros en salud con el sistema actual?, ¿Cuáles han sido las principales fallas o problemas en el sistema actual de salud?, ¿Hay un buen manejo de los fondos destinados al sistema de Salud actual?, ¿La gestión financiera del Sistema de Salud Colombiano, permite que este sea un sistema de salud sostenible y perdurable para todos los colombianos?. Adicionalmente, existen otros interrogantes a destacar como lo son ¿En qué consiste la nueva reforma de Salud propuesta para el 2013?, ¿Los cambios planteados en la última propuesta para hacer una reforma al sistema de salud, realmente conducen a un avance o dejan de lado los principales problemas de la seguridad social en Colombia?, ¿La nueva propuesta para la reforma de la salud busca lograr una mejora radical en la gestión financiera del Sistema de Salud Colombiano?, ¿Cuál es la percepción de los principales autores, especialistas en el tema en cuanto a la erradicación total de los problemas más álgidos en el actual Sistema de Salud Colombiano, con la nueva propuesta para la reforma de la salud para el 2013? Este trabajo de investigación surgió debido a la radicación de una nueva propuesta para la reforma a la salud y la polémica que se ha generado alrededor de esta. Veinte años después de la aprobación de la ley 100, se han identificado logros importantes principalmente en cuanto a cobertura; lastimosamente, actualmente se han manifestado problemas financieros y de liquidez, a pesar de lo cual, vale la pena destacar que el sistema fue rentable e incluso generó excedentes financieros en su operación, durante sus primeros 10 años de funcionamiento. Ahora, según la evidencia teórica investigativa y de la prensa nacional, se determinará si la nueva propuesta para la reforma de la salud es una buena opción para el país.

New classes of spatial central configurations for the n+3-body problem

In this paper, we show the existence of new families of spatial central configurations for the n + 3-body problem, n >= 3. We study spatial central configurations where n bodies are at the vertices of a regular n-gon T and the other three bodies are symmetrically located on the straight line that is perpendicular to the plane that contains T and passes through the center of T. The results have simple and analytic proofs. (c) 2010 Elsevier Ltd. All rights reserved.

ASTER: A Brazilian mission to an asteroid

The first Brazilian mission to an asteroid is being planned. The target is the asteroid 2001 SN263, which has a NEA orbit of class AMOR. Spectral analysis indicated that this is a C-type asteroid. This type of asteroids are dark and difficult to be studied from Earth. They hold clues of the initial stages of planetary formation and also the origin of water and life on Earth. In fact, radar data showed that 2001 SN263 is composed of three bodies with diameters of about 2.8 km, 1.1 km and 0.4 km. Therefore, the spacecraft will have the opportunity to explore three bodies on the same trip. The mission is scheduled to be launched in 2015, reaching the asteroid in 2018. It will be used a small spacecraft (150 kg) with 30 kg for the payload. The set of scientific instruments being considered to explore the target of this mission include an Imaging Camera, a Laser Rangefinder, an Infrared Spectrometer, a Synthetic Aperture Radar and a Mass Spectrometer. The main measurements to be made include the bulk properties (size, shape, mass, density, dynamics, spin state), the internal properties (structure, gravity field) and surface properties (mineralogy, morphology, elemental composition). The mission also opens an opportunity for some relevant experiments, not directly related to the target. Two such experiments will take benefit from being on board of the spacecraft along the journey to the asteroid system, which will take about three years. The first is an astrobiology experiment. The main goal of this experiment is to determine the viability of the microorganisms survival in extraterrestrial environments simulated in laboratory (chemical atmosphere, temperature, desiccation, vacuum, microgravity and radiation). The second experiment is a plasma package. The main objectives of this experiment are to study the structure and electrodynamics of plasma along the trajectory, the plasma instability processes and the density and temperature of plasma of solar wind origin along the trajectory and near the asteroids. This mission represents a great challenge for the Brazilian space program. It is being structured to allow the full engagement of the Brazilian universities and technological companies in all the necessary developments to be carried out. In this paper, we present some aspects of this mission and details of the payload that will be used and the scientific expectations. Copyright ©2010 by the International Astronautical Federation.

The aster mission: Exploring for the first time a triple system asteroid

2001 SN263 is a triple system asteroid. Although it was discovery in 2001, in 2008 astronomical observation carried out by Arecibo observatory revealed that it is actually a system with three bodies orbiting each other. The main central body is an irregular object with a diameter about 2.8 km, while the other two are small objects with less than 1 km across. This system presents an orbital eccentricity of 0.47, with perihelion of 1.04 and aphelion of 1.99, which means that it can be considered as a Near Earth Object. This interesting system was chosen as the target for the Aster mission - first Brazilian space exploration undertaking. A small spacecraft with 150 kg of total mass, 30 kg of payload with 110 W available for the instruments, is scheduled to be launched in 2015, and in 2018 it will approach and will be put in orbit of the triple system. This spacecraft will use electric propulsion and in its payload it will carry image camera, laser rangefinder, infrared spectrometer, mass spectrometer, and experiments to be performed in its way to the asteroid. This mission represents a great challenge for the Brazilian space program. It is being structured to allow the full engagement of the Brazilian universities and technological companies in all the necessary developments to be carried out. In this paper, we present some aspects of this mission, including the transfer trajectories to be used, and details of buss and payload subsystems that are being developed and will be used.

A new analysis of the GJ581 extrasolar planetary system

We have done a new analysis of the available observations of the GJ581 exoplanetary system. Today this system is controversial due to choices that can be done in the orbital determination. The main ones are the occurrence of aliases and the additional bodies-the planets f and g-announced in Vogt et al. (Astrophys J 723:954-965, 2010). Any dynamical study of exoplanets requires the good knowledge of the orbital elements and the investigations involving the planet g are particularly interesting, since this body would lie in the habitable zone (HZ) of the star GJ581. This region, for this system, is very attractive of the dynamical point of view due to several resonances of two and three bodies present there. In this work, we investigate the conditions under which the planet g may exist. We stress the fact that the planet g is intimately related with the orbital elements of the planet d; more precisely, we conclude that it is not possible to disconnect its existence from the determination of the eccentricity of the planet d. Concerning the planet f, we have found one solution with period a parts per thousand 450 days, but we are judicious about any affirmation concerning this body because its signal is in the threshold of detection and the high period is in a spectral region where the occurrence of aliases is very common. Besides, we outline some dynamical features of the HZ with the dynamical map and point out the role played by some resonances laying there.
