Thinking about complexity thinking in physical education

In the past two decades, complexity thinking has emerged as an important theoretical response to the limitations of orthodox ways of understanding educational phenomena. Complexity provides ways of understanding that embrace uncertainty, non-linearity and the inevitable ‘messiness’ that is inherent in educational settings, paying attention to the ways in which the whole is greater than the sum of its parts. This is the first book to focus on complexity thinking in the context of physical education, enabling fresh ways of thinking about research, teaching, curriculum and learning. Written by a team of leading international physical education scholars, the book highlights how the considerable theoretical promise of complexity can be reflected in the actual policies, pedagogies and practices of physical education (PE). It encourages teachers, educators and researchers to embrace notions of learning that are more organic and emergent, to allow the inherent complexity of pedagogical work in PE to be examined more broadly and inclusively. In doing so, Complexity Thinking in Physical Education makes a major contribution to our understanding of pedagogy, curriculum design and development, human movement and educational practice.

Population, globalization and urbanization: Trends and underlying prosesses

Third World hinterlands provide most of the settings in which the quality of human life has improved the least over the decade since Our Common Future was published. This low quality of life promotes a desire for large number of offspring, fuelling population growth and an exodus to the urban centres of the Third World, Enhancing the quality of life of these people in ways compatible with the health of their environments is therefore the most significant of the challenges from the perspective of sustainable development. Human quality of life may be viewed in terms of access to goods, services and a satisfying social role. The ongoing processes of globalization are enhancing flows of goods worldwide, but these hardly reach the poor of Third World countrysides. But processes of globalization have also vastly improved everybody's access to Information, and there are excellent opportunities of putting this to good use to enhance the quality of life of the people of Third World countrysides through better access to education and health. More importantly, better access to information could promote a more satisfying social role through strengthening grass-roots involvement in development planning and management of natural resources. I illustrate these possibilities with the help of a series of concrete experiences form the south Indian state of Kerala. Such an effort does not call for large-scare material inputs, rather it calls for a culture of inform-and-share in place place of the prevalent culture of control-and-command. It calls for openness and transparency in transactions involving government agencies, NGOs, and national and transnational business enterprises. It calls for acceptance of accountability by such agencies.

A agenda do desenvolvimento na promoção dos direitos humanos: uma análise da política externa brasileira no governo Lula

Os direitos humanos consolidaram um conjunto de valores ético-políticos considerados fundamentais para assegurar o respeito à dignidade do ser humano. A problemática do desenvolvimento é fundamental para as considerações de política externa de países como o Brasil. A consagração do Direito ao Desenvolvimento (DaD) como um direito humano desafia a divisão artificial dos direitos humanos e revela a evolução temática deste campo de estudo. Essa dissertação usa o instrumental dos direitos humanos para avaliar a relevância e a singularidade de algumas posições brasileiras. Após uma dissonância observada nos anos 1970, reflexo do ciclo autoritário por que passava o país, verificou-se postura cooperativa do Brasil nas proposições que versavam sobre o DaD. No mesmo sentido, observou-se que, conquanto não seja conceito recorrente no discurso oficial brasileiro, as posições do país, no que dizem respeito ao modelo de desenvolvimento defendido e aos direitos humanos, autorizam a inferência de que há uma harmonia em relação aos princípios fundamentais dispostos na Declaração sobre o DaD, de 1986. Da análise das posições brasileiras, tornou-se possível particularizar a política externa do governo Lula. Do levantamento das variáveis internas e externas que exercem influência sobre a formulação política do governo, bem como das iniciativas públicas e dos discursos oficiais, encontramos alguma evidência empírica no sentido de que a política externa brasileira para os direitos humanos, na administração de Luiz Inácio Lula da Silva, passa por um viés de promoção do desenvolvimento e de crítica à ordem internacional. A política se singulariza por incorporar uma dimensão de valores à crítica. Com isso, harmoniza-se com as posições defendidas pelo país nos plenários internacionais, onde o tema do DaD tem sido objeto de debate.

Molecular genetics of the imprinted gene - SPROUTY3 (SPRY3)

Sprouty proteins are key regulators of cell growth and branching morphogenesis during development. Human SPRY3 which maps to the pseudoautosomal region 2, undergoes random X-inactivation in females and preferential Y-inactivation in males, behaving as though genetically X-linked. Spry3 is widely expressed in neuronal tissues, being found at high levels in the cerebellum and particularly in the Purkinje cells which, notably, are deficient in the autistic brain. Spry3 is also highly expressed in other ganglia in adults including retinal ganglion cells, dorsal root ganglion and superior cervical ganglion. SPRY3 enhancer can drive SPRY3 expression in the lung airway, which is consistent with a role in branching morphogenesis and the function of the original Drosophila Spry gene, which is critical for lung morphogenesis, providing a possible explanation for an observed anatomic abnormality in the autistic lung airway. In the human and mouse, the SPRY3 core promoter contains an AG-rich repeat and we found evidence of coexpression, promoter binding and regulation of SPRY3 expression by transcription factors EGR1, ZNF263 and PAX6. Spry3 over-expression in mouse superior cervical ganglion cells inhibits axon branching and Spry3 knockdown in those cells increases axon branching, consistent with known functions of other Sprouty proteins. Novel SPRY3 upstream transcripts that I characterised originate from three start sites in the X-linked F8A3 – TMLHE gene region, which is recently implicated in autism causation. Arising from these findings, I propose that the lung airway abnormality and low levels of blood carnitine found in autism suggest that deregulation of SPRY3 may underpin a subset of autism cases.

Violence Exposure and Welfare over Time: Evidence from the Burundi Civil War

We investigate the relationship between exposure to conflict and poverty dynamics over time, using original three-waves panel data for Burundi which tracked individuals and reported local-level violence exposure from 1998 to 2012. Firstly, the data reveal that headcount poverty has not changed since 1998 while we observe multiple transitions into and out of poverty. Moreover, households exposed to the war exhibit a lower level of welfare than non-exposed households, with the difference between the two groups predicted to remain significant at least until 2017, i.e. twelve years after the conflict termination. The correlation between violence exposure and deprivation over time is confirmed in a household-level panel setting. Secondly, our empirical investigation shows how violence exposure over different time spans interacts with households' subsequent welfare. Our analysis of the determinants of households' likelihood to switch poverty status (i.e. to fall into poverty or escape poverty) combined with quantile regressions suggest that, (i) exposure during the first phase of the conflict has affected the entire distribution, and (ii) exposure during the second phase of the conflict has mostly affected the upper tail of the distribution: initially non-poor households have a higher propensity to fall into poverty while initially poor households see their propensity to pull through only slightly decrease with recent exposure to violence. Although not directly testable with the data at hand, these results are consistent with the changing nature of violence in the course of the Burundi civil war, from relatively more labour-destructive to relatively more capital-destructive.

Modelling pedestrian escalator behaviour

This paper presents an escalator model for use in circulation and evacuation analysis. As part of the model development, human factors data was collected from a Spanish underground station. The collected data relates to: escalator/stair choice, rider/walker preference, rider side preference, walker travel speeds and escalator flow rates. The dataset provides insight into pedestrian behaviour in utilising escalators and is a useful resource for both circulation and evacuation models. Based on insight derived from the dataset a detailed microscopic escalator model which incorporates person-person interactions has been developed. A range of demonstration evacuation scenarios are presented using the newly developed microscopic escalator model.

Relación entre los estilos de liderazgo y los niveles de resiliencia de los subordinados

El presente documento hace un análisis de la influencia que ejercen los diferentes tipos de liderazgo, carismático y transaccional, de un directivo de una organización sobre los subordinados de la misma, que a su vez afecta positiva o negativamente el nivel de resiliencia de los mismos. De la misma forma, se ha identificado la relación que existe entre el nivel de resiliencia de los subordinados de una organización y el cumplimiento de objetivos corporativos de la misma. Todo lo anterior se justifica en la economía globalizada de la que ahora hacemos parte que obliga a las empresas a generar nuevas estrategias de competitividad dentro de ambientes turbulentos y cambiantes donde, el desarrollar y motivar el recurso humano de la organización toma importancia para la ejecución exitosa de estrategias diferenciales.

Resiliencia organizacional y capital psicológico

Desde la noción universal sobre la empresa como un sistema de interacción con un entorno determinado para alcanzar un objetivo, de manera planificada y en función de satisfacer las demandas de un mercado mediante la actividad económica, su viabilidad, sostenibilidad y crecimiento dependerán, por supuesto, de una serie de estrategias adecuadas no solo para tales fines, sino también para enfrentar diversidad de agentes endógenos y exógenos que puedan afectar el normal desempeño de su gestión. Estamos hablando de la importancia de la resiliencia organizacional y del Capital Psicológico. En un escenario tan impredecible como el de la economía mundial, donde la constante son los cambios en su comportamiento —unos propios de su dinámica e interdependencia, naturales de fenómenos como la globalización, y otros derivados de eventos disruptivos— hoy más que nunca es necesario implementar el modelo de la empresa resiliente, que es aquella entidad capaz de adaptarse y recuperarse frente a una perturbación. Al mismo tiempo, más allá de su tamaño, naturaleza u objeto social, es indispensable reconocer básicamente que toda organización está constituida por personas, lo cual implica la trascendencia que para su funcionamiento tiene el factor humano-dependiente, y por lo tanto se crea la necesidad de promover el Capital Psicológico y la resiliencia a nivel de las organizaciones a través de una cultura empresarial.

Desarrollo de Montelíbano y Unión Matoso a partir de la explotación de Cerro Matoso S.A (2005-2015)

En este trabajo estudiaremos la explotación minera que realiza Cerro Matoso S.A en el sur del departamento de Córdoba a través del método cualitativo de investigación, basado en revisión de fuentes oficiales, entrevistas estructuradas y no estructuradas, como también en libros y fuentes académicas. Mediante este enfoque se pretende ver de qué manera ha influido la explotación de Cerro Matoso S.A en el desarrollo de los municipios Montelíbano y La Unión Matoso en el departamento de Córdoba, ya que a simple vista la explotación minera en dicho departamento no ha contribuido al desarrollo. Para ello se utilizaran los aportes teóricos de Amartya Sen y su teoría sobre desarrollo y libertades. Finalmente, este trabajo busca contrastar los discursos institucionales, y los testimonios de los habitantes de Montelíbano y La Unión Matoso.

Digital technology and creative arts career patterns in the UK creative economy

The creative industries have attracted the attention of academics and policy makers for the complexity surrounding their development, supply-chains and models of production. In particular, many have recognised the difficulty in capturing the role that digital technologies play within the creative industries. Digital technologies are embedded in the production and market structures of the creative industries and are also partially distinct and discernible from it. This paper unfolds the role played by digital technologies focusing on a key aspect of its development: human capital. Using student micro-data collected by the Higher Education Statistical Agency (HESA) in the United Kingdom, we investigate the characteristics and location determinants of digital graduates. The paper deals specifically with understanding whether digital skills in the UK are equally embedded across the creative industries, or are concentrated in other sub-sectors. Furthermore, it explores the role that these graduates play in each sub-sector and their financial rewards. Findings suggest that digital technology graduates tend to concentrate in the software and gaming sub-sector of the creative industries but also are likely to be in embedded creative jobs outside of the creative industries. Although they are more likely to be in full-time employment than part-time or self-employment, they also suffer from a higher level of unemployment.

Emerging health issues: the widening challenge for population health promotion

The spectrum of tasks for health promotion has widened since the Ottawa Charter was signed. In 1986, infectious diseases still seemed in retreat, the potential extent of HIV/AIDS was unrecognized, the Green Revolution was at its height and global poverty appeared less intractable. Global climate change had not yet emerged as a major threat to development and health. Most economists forecast continuous improvement, and chronic diseases were broadly anticipated as the next major health issue. Today, although many broadly averaged measures of population health have improved, many of the determinants of global health have faltered. Many infectious diseases have emerged; others have unexpectedly reappeared. Reasons include urban crowding, environmental changes, altered sexual relations, intensified food production and increased mobility and trade. Foremost, however, is the persistence of poverty and the exacerbation of regional and global inequality. Life expectancy has unexpectedly declined in several countries. Rather than being a faint echo from an earlier time of hardship, these declines could signify the future. Relatedly, the demographic and epidemiological   transitions have faltered. In some regions, declining fertility has overshot that needed for optimal age structure, whereas elsewhere mortality increases have reduced population growth rates, despite continuing high fertility. Few, if any, Millennium Development Goals (MDG), including those for health and sustainability, seem achievable. Policy-makers generally misunderstand the link between environmental sustainability (MDG #7) and health. Many health workers also fail to realize that social cohesion and sustainability—maintenance of the Earth’s ecological and geophysical systems—is a necessary basis for health. In sum, these issues present an enormous challenge to health. Health promotion must address population health influences that transcend national boundaries and generations and engage with the development, human rights and environmental movements. The big task is to promote sustainable environmental and social conditions that bring enduring and equitable health gains.

HRM research in China : looking back and looking forward

Purpose – The purpose of this paper is to provide an overview of the field of human resource management (HRM) in China, with insights drawn from recent times to several millennia earlier, with a view to informing the further work that needs to be done to better understand managing people in China.
Design/methodology/approach – The authors examined Chinese ancient texts related to people management and drew on reviews of HRM research in China since the establishment of the People’s Republic of China in 1949 till current times, to draw lessons for HRM in China today and for the future.
Findings – The 2,500 year gap that separates the literatures studied as part of this review cannot hide the striking similarities between the conceptual views about the importance of people and their management in the two periods. Yet, there remains a lack of empirical studies of the Chinese style of HRM practices. The majority of recent research in the field of HRM in China is focussed on comparison between HRM practices in various types of enterprises operating in China and those in the west, with the apparent aim of better understanding the latter rather than the former.
Originality/value – As China is rapidly becoming a key global player, and its enterprises represent an increasing share of the global market, it is crucial to understand how Chinese firms have managed their people at home and globally to achieve performance outcomes. Are there lessons other firms, especially those in emerging markets could learn? What are the implications for building global
management and organisational knowledge? This paper provides some directions for future research about HRM in China, which may help gain a better understanding of the Chinese style of management and further develop management and organisation theories in the China context.

Cancer stem cells in prostate cancer chemoresistance

There is currently no cure for metastatic castration-resistant prostate cancer (CRPC). Chemoresistance and metastatic disease remain the main causes of treatment failure and mortality in CaP patients. Although several advances have been made in the control of CRPC with some newly developed drugs, there is still an urgent need to investigate the mechanisms and pathways of prostate cancer (CaP) metastasis and chemoresistance, identify useful therapeutic targets, develop novel treatment approaches, improve current therapeutic modalities and increase patients' survival. Cancer stem cells (CSCs), a minority population of cancer cells characterised by self-renewal and tumor initiation, have gained intense attention as they not only play a crucial role in cancer recurrence but also contribute substantially to chemoresistance. As such, a number of mechanisms in chemoresistance have been identified to be associated with CSCs. Therefore, a thorough and integral understanding of these mechanisms can identify novel biomarkers and develop innovative therapeutic strategies for CaP treatment. Our recent data have demonstrated CSCs are associated with CaP chemosensitivity. In this review, we discuss the roles of putative CSC markers in CaP chemoresistance and elucidate several CSC-associated signaling pathways such as PI3K/Akt/mTOR, Wnt/β-catenin and Notch pathways in the regulation of CaP chemoresistance. Moreover, we will summarize emerging and innovative approaches for the treatment of CRPC and address the challenging CRPC that is driven by CSCs. Understanding the link between CSCs and metastatic CRPC will facilitate the development of novel therapeutic approaches to overcome chemoresistance and improve the clinical outcomes of CaP patients.
