Educational psychologists’ responses to a post-16 service user film on their practice: a participatory research project

A film was made by a group of young people (YP) which aimed to inform educational psychologists (EPs) about how they would like EPs to work with them. A participatory research project was established with the YP which aimed to find out EPs’ views on the film through two focus groups. EPs responded positively to the film; they valued hearing from YP and expressed feelings including pride and guilt . Interest was shown in plans for the distribution of the film and critical reflections on the representativeness of the film were made. Findings are discussed in relation to the current context for EP work in which there is a focus on gaining the voice of children and YP and on improving services through service-user feedback. The authors reflect on the strengths and limitations of using a participatory approach, considering challenges regarding methodological rigour and the opportunity research poses for widening participation

Involution products in Coxeter groups

For W a Coxeter group, let = {w ∈ W | w = xy where x, y ∈ W and x 2 = 1 = y 2}. It is well known that if W is finite then W = . Suppose that w ∈ . Then the minimum value of ℓ(x) + ℓ(y) – ℓ(w), where x, y ∈ W with w = xy and x 2 = 1 = y 2, is called the excess of w (ℓ is the length function of W). The main result established here is that w is always W-conjugate to an element with excess equal to zero

Firewood, food and niche construction : the potential role of Mesolithic hunter-gatherers in actively structuring Scotland's woodlands.

Over the past few decades the potential role of Mesolithic hunter–gatherers in actively constructing their own niches, through the management of wild plants, has frequently been discussed. It is probable that Mesolithic hunter–gatherers systematically exploited specific woodland resources for food and fuel and influenced the ‘natural’ abundance or distribution of particular species within Mesolithic environments. Though there has been considerable discussion of the pollen evidence for potential small-scale human-woodland manipulation in Mesolithic Scotland, the archaeobotanical evidence for anthropogenic firewood and food selection has not been discussed in this context. This paper assesses the evidence for the active role of Mesolithic hunter–gatherer communities in systematically exploiting and managing woodlands for food and fuel in Scotland. While taphonomic factors may have impacted on the frequency of specific species in archaeobotanical assemblages, it is suggested that hunter–gatherers in Mesolithic Scotland were systematically using woodland plants, and in particular hazel and oak, for food and fuel. It is argued that the pollen evidence for woodland management is equivocal, but hints at the role of hunter–gatherers in shaping the structure of their environments, through the maintenance or creation of woodland clearings for settlement or as part of vegetation management strategies. It is proposed that Mesolithic hunter–gatherers may have actively contributed to niche construction and that the systematic use of hazel and oak as a fuel may reflect the deliberate pruning of hazel trees to increase nut-yields and the inadvertent – or perhaps deliberate – coppicing of hazel and oak during greenwood collection

Measurement of electron density and temperature in plasmas

Application of two laser wavelengths passing through plasma measures electron density and temperature. Function depends on determining absorption of light at two wavelengths. Nature of reaction is explained and schematic diagram of equipment is included

Zooarchaeology and the elusive feast: from performance to aftermath

Ethnographic descriptions of feasts reveal that consumption of meat is usually prominent. Zooarchaeological evidence may thus provide the best way of seeing feasts in the archaeological record. The accumulation of trophy arrays and ongoing high-status activities are confusing behaviours that may be misconstrued as archaeological evidence of feasts. A four-fold classification of zooarchaeological evidence for feasts is put forward: ‘over the top’ (high status); ‘ritually charged garbage’ (often religious); ‘small but special’ (nevertheless sometimes visible); and ‘was this feasting?’ (sometimes equivocal). This typology may allow archaeologists to distinguish between the ethnographic categories of competitive feasts and solidarity feasts

Derivation and application of a Food Utility Index (FUI) for European wild boar (Sus scrofa L.)

A Food Utility Index (FUI) is presented for European wild boar (Sus scrofa L.), derived from the experimental butchery of two individuals of differing ages. The results differ from FUIs produced for other species because of the different conformation of the species. Application of the FUI to the wild boar assemblage from the Mesolithic site of Ringkloster (Denmark) allows increased understanding of field butchery, transport and processing of the animals

Mesolithic domestic pigs at Rosenhof – or wild boar? A critical re-appraisal of ancient DNA and geometric morphometrics

We challenge the claim by Krause-Kyora et al. (2013) that there were domestic pigs at Mesolithic sites in northern Germany. A small number of animals from Rosenhof and Poel have ancient DNA and geometric morphometric signatures elsewhere associated with domestic animals. At this time Neolithic farming settlements were present 150km to the south, but the Mesolithic specimens are, however, metrically wild boar, much larger than domestic pigs, and cannot be domestic individuals acquired from the farmers. A more likely explanation for these ‘domestic’ traits is that animals that escaped from farmers’ pig herds interbred with local wild boar. Their descendants were morphologically and behaviourally wild, and were shot by Mesolithic foragers in the course of normal hunts. Their presence at Mesolithic sites is not a precursor to agriculture

Wild things in the north? Hunter-gatherers and the tyranny of the colonial perspective

The paper argues for a synthesis of Darwinian and Marxist theories of evolution. We challenge claims that hunter-gatherer societies evolve via a natural progression from simple to complex, arguing instead that huntergatherer social strategies are adaptations to specifiable ecological conditions, while having emergent consequences that shape the political structure of hunter-gatherer society. We review the various theories of which we make use, and those that we challenge, and test them against data from the ethnographic and archaeological literature on hunter-gatherers, discussing the evidence for variation in technology, mobility, territoriality and egalitarianism versus social inequality. We conclude that human societies do not evolve via a natural progression from simple to complex forms, and that complex hunter-gatherers are not necessarily incipient farmers. Many of the assumptions that colour common views of the development of hunter-gatherer complexity and the appearance of agriculture in prehistoric Europe have their roots, consciously or unconsciously, in nineteenth-century European colonialism
