Urban Pattern

The archaeological excavation campaign carried out during the year 2014 on the plateau of Giribaile had the objectives of a) providing better knowledge of the inner structure of the oppidum and its urban pattern and b) documenting the floor of one house enclosed within Area 3. The archaeological excavation of Area 3 made it possible to characterise a multi-functional structure from fourth and third centuries BCE inside the urban pattern. Carpological, anthropological and soil micromorphology studies as well as phytoliths, pottery and 14C analyses were performed. The study of the urban pattern using orthophotography showed a planned design. The identification of numerous functions related to farming inside Area 3 suppose an important advancement towards the complete understanding of crop and livestock farming in the Iberian culture.

Livestock Farming Systems

Pasture characteristics, soil moisture relations and water balance were measured in open pasture and in a mature poplar understorey, to assess how land conservation practices modify a pastoral system. Mature poplars changed the environment of the understorey pasture, with light intensity decreased from September to April, and the soil generally colder and drier in autumn and early winter. Soil moisture relations did not suggest strong competition for water between trees and pasture in spring. Pasture under the poplars accumulated 40% less herbage mass and was of lower feed quality than pasture in the open. The case study highlights the complexity of silvipastoral systems in hill country and the need for a more complete understanding of the interactions if the potential of a multipurpose tree and livestock farming systems is to be realised.

And Function

The present knowledge of the three-dimensional structure of ribosomes is far too limited to enable a complete understanding of the various roles which ribosomes play in protein biosynthesis. The spatial arrangement of proteins and ribonuclec acids in ribosomes can be analysed in many ways. Determination of binding sites for individual proteins on ribonuclec acid and locations of the mutual positions of proteins on the ribosome using labeling with fluorescent dyes, cross-linking reagents, neutron-diffraction or antibodies against ribosomal proteins seem to be most successful approaches. Structure and function of ribosomes can be correlated be depleting the complete ribosomes of some proteins to the functionally inactive core and by subsequent partial reconstitution in order to regain active ribosomal particles.

Recent progress in the application of scanning tunneling microscopy (STM) and tunneling spectroscopy (STS) to oxide surfaces has allowed issues of image formation mechanism and spatial resolution limitations to be addressed. As the STM analyses of oxide surfaces continues, it is becoming clear that the geometric and electronic structures of these surfaces are intrinsically complex. Since STM requires conductivity, the oxides in question are transition metal oxides that accommodate aliovalent dopants or nonstoichiometry to produce mobile carriers. To date, considerable effort has been directed toward probing the structures and reactivities of ZnO polar and nonpolar surfaces, TiO2 (110) and (001) surfaces and the SrTiO3 (001) surface, with a view towards integrating these results with the vast amount of previous surface analysis (LEED and photoemission) to build a more complete understanding of these surfaces. However, the spatial localization of the STM/STS provides a level of detail that leads to conclusions somewhat different from those made earlier.

Abstract. Meta-accuracy and perceptions of reciprocity can be measured by covariances between latent variables in two social relations models examining perception and meta-perception. We propose a single unified model called the Perception-Meta-Perception Social Relations Model (PM-SRM). This model simultaneously estimates all possible parameters to provide a more complete understanding of the relationships between perception and meta-perception. We describe the components of the PM-SRM and present two pedagogical examples with code, openly available on https://osf.io/4ag5m . Using a new package in R (xxM), we estimated the model using multilevel structural equation modeling which provides an approachable and flexible framework for evaluating the PM-SRM. Further, we discuss possible expansions to the PM-SRM which can explore novel and exciting hypotheses.

Conversion of native vegetation into farmed grassland in the Lake Taupo catchment commenced in the late 1950s. The lake's iconic value is being threatened by the slow decline in lake water quality that has become apparent since the 1970s.

Hill Farming

This paper is not a formal review of hill farming literature. Rather, it is my view on the critical challenges and changes that we need to deal with if mixed livestock farming on hill lands is to be successful over the next 20 years. It is my hope that industry leaders, policy makers and agribusiness managers will give consideration to these views. Some people say that it is not smart to look into the rear-vision mirror, but I do not agree. Having a better understanding of the consequences of past events can help guide future decisions and changes.

Summary An archaeological excavation was carried out at Graham Street, Leith, Edinburgh by Glasgow University Archaeological Research Division (GUARD) as part of the Historic Scotland Human Remains Call-off Contract following the discovery of human remains during machine excavation of a foundation trench for a new housing development. Excavation demonstrated that the burial was that of a young adult male who had been interred in a supine position with his head orientated towards the north. Radiocarbon dates obtained from a right tibia suggest the individual died between the 15th and 17th centuries AD. Little contextual information exists in documentary or cartographic sources to supplement this scant physical evidence. Accordingly, it is difficult to further refine the context of burial, although a possible link with a historically attested siege or a plague cannot be discounted.

An archaeological excavation of four areas approximately 0.39ha in total, of land at Watery Lane, Church Crookham, Hampshire, was undertaken by Cotswold Archaeology in November and December 2016. It followed the recording of two Pill Boxes and a trial trench evaluation of a wider development area. In all four areas archaeological features were identified. The artefactual evidence indicated five phases of archaeological activity, with features dating from the late prehistoric, medieval, medieval/post-medieval, and post-medieval to modern wartime period. Several heavily truncated isolated prehistoric features were identified, as were field boundary ditches of medieval to the post-medieval date. Many undated, but presumed modern, postholes were found across the site. The postholes may have been the result of an extensive network of Second World War temporary timber structures known as tactical obstacles (including barbed wire entanglements and tank proof obstacles) erected during anti-invasion defence works. These structures were likely to have been part of the important Stop Line Defence network, Line A of the GHQ (General Headquarters) line of defences, which were planned to slow down a ground invasion.

In March 2016, archaeological excavation was undertaken at four areas of land at Oxlease Farm, Cupernham Lane, Romsey, Hampshire. The fieldwork recovered a lithic assemblage from all four excavation areas, although the majority was recorded from a single flint-bearing deposit in Area 1. The assemblage included several elements that may belong to the Terminal Upper Palaeolithic Long Blade industry, as well as three flints of Mesolithic date. A small number of undated features were also uncovered, including pits and possible postholes, which may have been of a prehistoric date. A small and residual assemblage of Late Roman (3rd – 4th century AD) pottery was also recovered from probable medieval/post-medieval field boundary ditches or plough furrows.
