Personal, social, health and economic (PSHE) education: A mapping study of the prevalent models of delivery and their effectiveness

In October 2008, then Schools Minister Ji, Knight announced that Personal, Social, Health and Economic (PSHE) education would become compulsory (for Key Stages 1-4). Following this, In November 2009, Sheffield Hallam University was contracted by DCSF (now DfE) to conduct a mapping exercise of PSHE education in primary and secondary schools in England. This resulted from a recommendation in the Macdonald Review, whcih identified the need for research to establish and report on the prevalent models of delivery for PSHE education and their effectiveness in improving outcomes for children and young people (Macdonald, 2009:8)

Teams, HRM and innovation:an organisation-level analysis

For organizations to survive and prosper they have to develop new and improved products, services and ways of working. Innovation is vital for organizational survival. Much research and managerial attention is therefore devoted to understanding the factors that predict innovation in organizations. This paper describes a research study of product innovation in manufacturing organizations and explores the extent to which team based working and team working effectiveness in these organizations predict product innovation. It also considers whether combinations of good HRM systems and practices, extensive team based working and effective team working are associated with product innovation

Uniformity and Diversity in Handaxe Shape at the End of the Acheulean in Southwest Asia

This study examines parameters, causes, and spatio-temporal patterns of handaxe shape variation from Tabun cave in the Levant, and Khall Amayshan 4B and Khabb Musayyib in northern Arabia. These assemblages span the range of most pointy to most rounded handaxes found anywhere during the Acheulean. The AGMT3D program is used to conduct high resolution geometric morphometric analysis of handaxe form from 3D models. Shape variation is tested against blank type, allometry, and reduction intensity. None of these factors appears to be a strong influence, but there are significant assemblage-wise differences in form, suggesting the different shapes were intentionally produced. The analysis quantifies a pattern of high diversity in the assemblages from Tabun versus low diversity in the shorter occupations at the Arabian sites. We suggest possible explanations of emerging specificity in utilitarian functions, as well as the manifestation of social identities in artefacts at the end of the Acheulean

Plant, pigment, and bone processing in the Neolithic of northern Arabia-New evidence from Use-wear analysis of grinding tools at Jebel Oraf

Archaeological sites with surface hearths are a ubiquitous feature across the arid zones of the Arabian interior. At Jebel Oraf, in the Jubbah basin of the Nefud Desert of northern Arabia, numerous grinding stone fragments were found in association with hearths, though the original purpose of these stones was unclear owing to the poor preservation of faunal and botanic remains. Here we describe results from use-wear analysis on five grinding tools at Jebel Oraf, demonstrating that such artefacts were used during the Neolithic for plant processing, bone processing, and pigment production. Grinding stones were often broken up after initial use and fragments were subsequently re-used for alternative purposes, before finally being placed on hearths or discarded. More specifically, plants were ground or prepared and possibly cooked in the hearths, and bones were processed as well. The analyses also highlight the importance of pigment processing at Neolithic sites and provide a link to painted rock art. The frequent use of pigment in the archaeological record suggests that pigment was widely used, and that Neolithic painted art may have been more common than the surviving images suggest

An illustrated prehistory of the Jubbah Oasis: reconstructing Holocene occupation patterns in northwestern Saudi Arabia from rock art and inscriptions

A systematic survey of rock art and associated archaeological features in the Jubbah oasis provides evidence of Holocene occupation from the early Holocene to the present. In total, 1249 panels with rock art and inscriptions, and 159 archaeological sites were recorded on 12 different jebels. Analyses of rock art content and engraving stratigraphy indicate that the iconic Jubbah style had a long tradition amongst pre-pastoral hunters and continued to be used by early herders. We also identify a distinct body of rock art that pre-dates the Jubbah style and may be associated with a nearby Epipalaeolithic site. Our systematic dataset identifies a body of Bronze Age rock art that is further supported by the material culture and radiocarbon dates obtained from the remains of disturbed cairns. The rock art in Jubbah appears to have been created throughout the Holocene occupation of the oasis and similarities in the representation of animals, the choice of location, and the content of rock art scenes are evident from the Bronze Age to the early modern period, and perhaps into the 20th century. Moreover, rock art and epigraphy suggest that occupation phases in Jubbah were sustained long enough for the repeated development of unique local characteristics throughout the Holocene

A Quaternary sequence of terrestrial molluscs from East Africa: a record of diversity, stability, and abundance since Marine Isotope Stage 5 (78,000 BP)

A Quaternary sequence of subfossil terrestrial molluscs from tropical Kenya is described and discussed. It preserves a remarkably complete fauna of the Indian Ocean coastal forest from the surroundings of Panga ya Saidi cave, a site featuring repeated human occupation extending back at least 78, 000 years. Mollusc diversity, composition, and abundance are very similar to extant faunas of the coastal forest. They vary relatively little over the period studied (chiefly a 50,000-year sequence from MIS 5 to the start of MIS 2) apart from a short-lived decrease in the dominance of “forest-only” species around 45,800 BP. The fauna of the most recently preserved layers (MIS 1) is likewise similar. Most of the 72 snail (and slug) species found are still extant at the coast, including some narrow-range endemics, but 8 species are now more western in their known distribution. The native African status of Kaliella barrakporensis and 2 other snail species with Asian type localities are confirmed, as is the previously disputed occurrence of native Helicoidea at the coast. Two new subfossil species were identified and are described as Maizania meteor sp. n. (Maizaniidae) and Juventigulella saidii sp. n. (Streptaxidae). No major habitat or faunistic shifts are observed, confirming previous evidence for long-term ecological continuity at the site. The data are the first of their kind from coastal East Africa and provide a new independent proxy of the environmental context to the archaeological sequence, as well as a reference point for future studies of terrestrial molluscs in the region

Expedient synthesis and luminescence sensing of the inositol pyrophosphate cellular messenger 5-PP-InsP5

Inositol pyrophosphates are important biomolecules associated with apoptosis, cell growth and kinase regulation, yet their exact biological roles are still emerging and probes do not exist for their selective detection. We report the first molecular probe for the selective and sensitive detection of the most abundant cellular inositol pyrophosphate 5-PP-InsP5, as well as an efficient new synthesis. The probe is based on a macrocyclic Eu(III) complex bearing two quinoline arms providing a free coordination site at the Eu(III) metal centre. Bidentate binding of the pyrophosphate group of 5-PP-InsP5 to the Eu(III) ion is proposed, supported by DFT calculations, giving rise to a selective enhancement in Eu(III) emission intensity and lifetime. We demonstrate the use of time-resolved luminescence as a bioassay tool for monitoring enzymatic processes in which 5-PP-InsP5 is consumed. Our probe offers a potential screening methodology to identify drug-like compounds that modulate the activity of enzymes of inositol pyrophosphate metabolism
