A new laser-ranged satellite for General Relativity and space geodesy: I. An introduction to the LARES2 space experiment

We introduce the LARES 2 space experiment recently approved by the Italian Space Agency (ASI). The LARES 2 satellite is planned for launch in 2019 with the new VEGA C launch vehicle of ASI, ESA and ELV. The orbital analysis of LARES 2 experiment will be carried out by our international science team of experts in General Relativity, theoretical physics, space geodesy and aerospace engineering. The main objectives of the LARES 2 experiment are gravitational and fundamental physics, including accurate measurements of General Relativity, in particular a test of frame-dragging aimed at achieving an accuracy of a few parts in a thousand, i.e., aimed at improving by about an order of magnitude the present state-of-the-art and forthcoming tests of this general relativistic phenomenon. LARES 2 will also achieve determinations in space geodesy. LARES 2 is an improved version of the LAGEOS 3 experiment, proposed in 1984 to measure frame-dragging and analyzed in 1989 by a joint ASI and NASA study

Fundamental Physics and General Relativity with the LARES and LAGEOS satellites

Current observations of the universe have strengthened the interest to further test General Relativity and other theories of fundamental physics. After an introduction to the phenomenon of frame-dragging predicted by Einstein's theory of General Relativity, with fundamental astrophysical applications to rotating black holes, we describe the past measurements of frame-dragging obtained by the LAGEOS satellites and by the dedicated Gravity Probe B space mission. We also discuss a test of String Theories of Chern-Simons type that has been carried out using the results of the LAGEOS satellites. We then describe the LARES space experiment. LARES was successfully launched in February 2012 to improve the accuracy of the tests of frame-dragging, it can also improve the test of String Theories. We present the results of the first few months of observations of LARES, its orbital analyses show that it has the best agreement of any other satellite with the test-particle motion predicted by General Relativity. We finally briefly report the accurate studies and the extensive simulations of the LARES space experiment, confirming an accuracy of a few percent in the forthcoming measurement of frame-dragging.Comment: To be publihed in Nuclear Physics. arXiv admin note: substantial text overlap with arXiv:1306.1826, arXiv:1211.137

The unheard voices of Africa

This paper reflects on how the female subaltern constantly searches for a way to negotiate her repressive circumstances while she struggles against surrendering to a muted space. Different images of African women, as portrayed by two contemporary African female writers, namely Tsitsi Dangarembga (1959 -) and Yvonne Vera (1964 -2005), have been traced in order to depict these women's social realities. These authors present a critique of African societies that have been pushing women's voice into marginality. The paper argues that, contrary to Spivak's notion that the subaltern cannot speak, these authors present new and different subjectivities of women who challenge the myth of the silent subalternpeer-reviewe

Lifelong learning in later life : a handbook on older adult learning

Lifelong learning in later life is an essential handbook for a wide range of people who work alongside older adults in varied contexts. This handbook brings together both orthodox approaches to educational gerontology and fresh perspectives on important emerging issues faced by seniors around the globe. Issues discussed include the social construction of ageing, the importance of lifelong learning policy and practice, participation in later life learning, education of marginalised groups within older communities, inter-generational learning, volunteering and ‘active ageing’, the political economy of older adulthood, learning for better health and well-being, and the place of seniors in a learning society.N/

The construction of the risk of falling among and by older people

Risk is frequently invoked in contemporary accounts of ill health, but its construction is often constrained by a rationalist perspective that focuses on physical causes and functional outcomes, and that presents risk as external to the self and predictable. This paper describes an empirical study of the ways in which risk was realised and managed in a day hospital for older people. An ethnographic approach, with participant observation and semi-structured interviews, and discourse analysis were used to explore these issues with the staff and fifteen users. Whilst the service providers were orientated to the management of physical risk, as through the regimes for administering medication and their attention to risk reduction in the physical environment, the service users were more concerned with the risk to their personal and social identities, and they more frequently described its manifestations in inter-personal exchanges, sometimes as infantalisation and stereotyping. The paper develops this understanding of the potential for falls among older people to elucidate a broader interpretation of risk, and reveals that it is commonly constructed as a challenge to a person's self-image and identity. Such constructions help to explain older people's responses to complex health problems and to the services and treatments that attempt to solve them

Editor\u27s Introduction

IN recent years numerous reports have appeared in the news about the objections of various Hindu and Christian groups to the adoption of yoga by Christians and other non-Hindus. The main theme of this issue of the JHCS is to address this controversy from different perspectives, with Patañjali’s Yogasūtras as the main focus

Core Aspects of Dance: Schiller and Dewey on Grace

Part of a larger project of constructing a new, historically informed philosophy of dance, built on four phenomenological constructs that I call “Moves,” this essay concerns the third Move, “grace.” The etymology of the word “grace” reveals the entwined meanings of pleasing quality and authoritative power, which may be combined as “beautiful force.” I examine the treatments of grace in German philosopher Friedrich Schiller, who understands it as playful, naive transformation of matter; and in American philosopher John Dewey, for whom it represents rhythmic organism/environment reversal. I conclude by showing how “grace” can be used in analyzing various types of dance, which in turn suggests transformational potential for philosophy, dance, and society as a whole

What is the Evidence of the Experience of Having a Fall across the Life Course? A Qualitative Synthesis

Background: Alleviating the economic and human impacts of falls and fear of falling are critical health and social care issues. Despite some proven effectiveness of a number of falls prevention intervention programmes, uptake remains low and attrition high. There is a need for greater understanding of social, cultural and individual, life course positioning of falling, actual or perceived. Objective: To address the question: what is the evidence of the experience of having a fall across the life course? Method: A qualitative evidence synthesis with key electronic databases searched from 1990-2011 using terms related to the experience of falls and falling. Selected papers presented data from the perspective of the person who had fallen. Synthesis included collaborative coding of ‘incidents’ related to falling, theoretical sampling of studies to challenge emerging theories, and constant comparison of categories to generate explanations. Results: The initial focus was to access and assess the evidence for the experiences of a fall across the life course but the authors’ systematic search revealed that the vast majority of the published literature focuses on the experience of a fall in later life. Only 2 of the 16 studies included, provided perspectives of falling from a life stage other than that of older adults. However older adults’ perceptions of their falls experiences are likely to be influenced by lifelong attitudes and beliefs about falling and older age. Synthesis identified that a falls incident or fear of falling induces explicit or implicit ‘Fear’. Consequences are related to notions of ‘Control’ and ‘Social standing’. Recovery work involves ‘Adaptation’, ‘Implications’ ‘Social standing’ and ‘Control’. ‘Explanation’ is sought. Conclusions: How and why people make sense of falling across the life course should have positive impacts on developing falls intervention programmes that people will want to engage with and adhere to
