We present a one per cent measurement of the cosmic distance scale from the detections of the baryon acoustic oscillations in the clustering of galaxies from the Baryon Oscillation Spectroscopic Survey, which is part of the Sloan Digital Sky Survey III. Our results come from the Data Release 11 sample, containing nearly one million galaxies and covering approximately 8500 square degrees and the redshift range 0.2 < z < 0.7. We also compare these results with those from the publicly released (...) DR9 and DR10 samples. Assuming a concordance Λ cold dark matter cosmological model, the DR11 sample covers a volume of 13 Gpc3 and is the largest region of the Universe ever surveyed at this density. We measure the correlation function and power spectrum, including density-field reconstruction of the BAO feature. The acoustic features are detected at a significance of over 7σ in both the correlation function and power spectrum. Fitting for the position of the acoustic features measures the distance relative to the sound horizon at the drag epoch, rd, which has a value of rd,fid = 149.28 Mpc in our fiducial cosmology. We find DV = at z = 0.32 and DV = at z = 0.57. At 1.0 per cent, this latter measure is the most precise distance constraint ever obtained from a galaxy survey. Separating the clustering along and transverse to the line of sight yields measurements at z = 0.57 of DA = and H =. Our measurements of the distance scale are in good agreement with previous BAO measurements and with the predictions from cosmic microwave background data for a spatially flat CDM model with a cosmological constant. © 2014 The Author Published by Oxford University Press on behalf of the Royal Astronomical Society.

Concept definitions applicable to human and non-human animals should be usable for both. Awareness is a state during which concepts of environment, self, and self in relation to environment result from complex brain analysis of sensory stimuli or constructs based on memory. There are several proposed categories of awareness. The widespread usage of the term conscious is 'not unconscious' so a conscious individual is an individual that has the capability to perceive and respond to sensory stimuli. It is confusing and (...) scientifically undesirable if conscious is also used to mean aware. Hence it is proposed that conscious should be used only as above. Fully functioning and adequately developed humans and members of many other animal species are sentient. Sentience means having the capacity, the level of awareness and cognitive ability, necessary to have feelings. The welfare of an individual is its state as regards its attempts to cope with its environment. This includes feelings, which are important coping mechanisms, and health. Since feelings involve awareness, there is overlap between welfare assessment and awareness assessment. Methods for assessing awareness, consciousness, sentience, and welfare and links to morality are briefly discussed. (shrink)

Human attitudes to animals have changed as non-humans have become more widely incorporated in the category of moral agents who deserve some respect. Parallels between the functioning of humans and non-humans have been made for thousands of years but the idea that the animals that we keep can suffer has spread recently. An improved understanding of motivation, cognition and the complexity of social behaviour in animals has led in the last 30 years to the rapid development of animal welfare science. (...) Early attempts to define welfare referred to individuals being in harmony with nature but the first usable definition incorporated feelings and health as part of attempts to cope with the environment. Others considered that welfare is only about feelings but it is argued that as feelings are mechanisms that have evolved they are a part of welfare rather than all of it. Most reviews of welfare now start with listing the needs of the animal, including needs to show certain behaviours. This approach has used sophisticated studies of what is important to animals and has replaced the earlier general guidelines described as freedoms. Many measures of welfare are now used and indicate how good or how poor the welfare is. Naturalness is not a part of the definition of welfare but explains why some needs exist. In recent years, welfare has become established as one of various criteria used to decide on whether a system is sustainable because members of the public will not accept systems that cause poor welfare. The study of welfare has become part of the scientific basis upon which important political decisions are made. (shrink)

Donald Broom argues that morality and the central components of religion are of great value, and presents two central ideas. He asserts that morality has a biological foundation and has evolved as a consequence of natural selection, and that religions are essentially the structures supporting morality. Many philosophers and theologians write about morality and its origins without reference to biological processes such as evolution. Likewise, biologists discuss phenomena of importance to human morality and religion without taking account of the (...) thoughts of others on these subjects. (shrink)

Drawing on convergent work in a broad range of disciplines, this article uses the tipping point paradigm to frame a new account of how early human ancestors may have first broken free from, as Bickerton calls it, the “prison of animal communication.” Under building pressure for an enhanced signaling system capable of supporting joint attentional-intentional activities, a cultural tradition of disambiguated indexical pointing, combined with increasingly sophisticated mindreading circuitry and prosocial tendencies, may have sparked the first in the series of (...) biocultural explosions that led from a simple protolanguage to fully modern human language. This account successfully integrates at least ten other competing hypotheses, and is shown to pass nine important tests that have been proposed for language origin scenarios of its type. (shrink)

This paper sets out to give sufficient detail to the notion of mental simulation to allow an appraisal of its contribution to ‘mindreading’ in the context of the ‘false-belief tasks’ used in developmental psychology. We first describe the reasoning strategy of ‘modified derivation’, which supports counterfactual reasoning. We then give an analysis of the logical structure of the standard false-belief tasks. We then show how modified derivation can be used in a hybrid strategy for mindreading in these tasks. We then (...) formulate the hypothesis that children become able (around the age of 4 years) to pass these tasks when they acquire the counterfactual reasoning ability required in this strategy. We find this to be consistent with various empirical findings. We then discuss the implications for the theory/simulation debate, meta-representation and pretence. (shrink)

In _The Body in Late-Capitalist USA_, Donald M. Lowe explores the varied social practices that code and construct the body. Arguing that our bodily lives are shaped by a complex of daily and ongoing practices—how we work, what we buy and consume—Lowe contends that as a result of the commodification of these and other social practices in the late-twentieth century, what we often understand to be the needs of the body are in fact means for capital accumulation. Moving beyond (...) studies of representations and images of the body, Lowe focuses on the intersection of body practices, language, and the Social to describe concretely the reality of a lived body. His strongly synthetic work brings together Marxist critique, semiotics, Foucaultian discourse analysis, and systems and communications theory to examine those practices that construct the body under late capitalism: habits of work and consumption, the ways we give birth and raise children, socialization, mental and physical healing, reconstructions and contestations of sexuality and gender. Lowe draws upon a wide range of sources, including government and labor studies and statistics, diagnostic and statistical manuals on mental illness, computer manuals, self-help books, and guides to work-related stress disorders, to illustrate the transformation of the body into a nexus of exchange value in postmodern society.
