Early human use of marine resources and pigment in South Africa during the Middle Pleistocene

Abstract: Genetic and anatomical evidence suggests that Homo sapiens arose in Africa between 200 and 100 thousand years (kyr) ago, and recent evidence indicates symbolic behaviour may have appeared approximately 135-75 kyr ago. From 195-130 kyr ago, the world was in a fluctuating but predominantly glacial stage (marine isotope stage MIS6); much of Africa was cooler and drier, and dated archaeological sites are rare. Here we show that by approximately 164 kyr ago (+/-12 kyr) at Pinnacle Point (on the south coast of South Africa) humans expanded their diet to include marine resources, perhaps as a response to these harsh environmental conditions. The earliest previous evidence for human use of marine resources and coastal habitats was dated to approximately 125 kyr ago. Coincident with this diet and habitat expansion is an early use and modification of pigment, probably for symbolic behaviour, as well as the production of bladelet stone tool technology, previously dated to post-70 kyr ago. Shellfish may have been crucial to the survival of these early humans as they expanded their home ranges to include coastlines and followed the shifting position of the coast when sea level fluctuated over the length of MIS6.

INTRODUCTION Since January 1993, ‘Progress in Photovoltaics’ haspublished six monthly listings of the highest confirmedefficiencies for a range of photovoltaic cell and moduletechnologies [1–3]. By providing guidelines for theinclusion of results into these tables, this not only providesan authoritative summary of the current state of the art butalso encourages researchers to seek independent confir-mation of results and to report results on a standardisedbasis. In a recent version of these tables (Version 33) [2],results were updated to the new internationally acceptedreferencespectrum(IEC60904–3,Ed.2,2008),wherethiswas possible.Themostimportantcriterionforinclusionofresultsintothe tables is that they must have been measured by arecognised test centre listed elsewhere [1]. A distinction ismade between three different eligible areas: total area;aperture area and designated illumination area [1]. ‘Activearea’ efficiencies are not included. There are also certainminimum values of the area sought for the different devicetypes (above 0.05cm

Are All Smiles Created Equal? How Emotional Contagion and Emotional Labor Affect Service Relationships:

Abstract: In this study, the authors examine the effects of two facets of employee emotions on customers' assessments of service encounters. Drawing on emotional contagion and emotional labor theories, they investigate the influence of the extent of service employees' display of positive emotions and the authenticity of their emotional labor display on customers' emotional states and, subsequently, on customers' assessments of the service interaction and their relationship with the service provider. To test the study hypotheses, 223 consumers participated in a simulated service encounter in which actors played the roles of service employees. In a 2 × 2 factorial design, the employees varied both the extent of their smiling behavior and their emotional labor display by engaging in surface or deep acting. The results show that the authenticity of employees' emotional labor display directly affects customers' emotional states. However, contrary to expectations, the extent of employee smiling does not influenc...

The kernel polynomial method

Abstract: Efficient and stable algorithms for the calculation of spectral quantities and correlation functions are some of the key tools in computational condensed-matter physics. In this paper basic properties and recent developments of Chebyshev expansion based algorithms and the kernel polynomial method are reviewed. Characterized by a resource consumption that scales linearly with the problem dimension these methods enjoyed growing popularity over the last decade and found broad application not only in physics. Representative examples from the fields of disordered systems, strongly correlated electrons, electron-phonon interaction, and quantum spin systems are discussed in detail. In addition, an illustration on how the kernel polynomial method is successfully embedded into other numerical techniques, such as cluster perturbation theory or Monte Carlo simulation, is provided.

Economic Rationalism in Canberra: A Nation-Building State Changes its Mind

Abstract: Throughout the world since the 1970s, state and public sector reform has been driven by a conservative agenda emphasising notions of 'streamlining' and 'rationalisation'; Australia has been no exception. Michael Pusey undertakes a detailed analysis of top bureaucrats in Canberra who have been responsible for this recasting of national policy. He concludes that economist rationalist view dominate each of the key ministries, and have altered the traditional balance between the economy, the state and society. The book also discusses the social significance of economic rationalisation and public sector reform from a theoretical perspective, contributing to contemporary understanding of modernisation, public morality and citizenship in the new global order.
