Student field experiences: designing for different instructors and variable weather

This study compares the field experience and development of sense of place (in this case, human attributed meanings and attachments to the field area) in geoscience students on three separate course sections of a six-day introductory geological mapping field trip. Students stayed in a small farm station within their 4 km² field area, worked in groups of three or four, and produced an individual final assessment. Findings from student interviews and pre-post surveys indicated that there were no significant differences in perceptions of the field trip purpose or sense of place between field trip sections, despite differences in instructor pedagogy and sense of place, as well as varied weather conditions. There were significant increases in student sense of place on all field trips, in contrast with previous work on a “roadside” (regional, multi-site) field trip where no significant change in sense of place occurred. In-field observations and instructor interviews identified key characteristics that supported similar sense of place and experiences on all trips: (1) consistent intended learning outcomes, (2) a carefully selected and immersive field area valued by instructors, and (3) an assessment connected to the landscape/field area with flexibility in its implementation, especially when faced with adverse weather conditions.     

The Political Economy of Class Compromise: Trade Unions,Capital–Labour Relations and Development in North East Brazil1

Abstract: This article investigates how capital–labour relations (encompassing processes of class formation, representation, struggle and compromise) impact on emerging regions’ developmental trajectories. It does so because much of development studies portray labour simply as an input (human capital) subordinate to more fundamental processes such as capital investment and accumulation. The paper draws on and extends insights gained from the “new working class studies” and global commodity chains literatures in order to examine evolving capital–labour relations—from relatively militant struggles to class compromise—in an emerging sector of North East Brazilian export horticulture. It identifies sources of workers’ structural and associational power and uses these to explain significant gains achieved by the region's rural trade union during the formation of the export horticulture sector. It then asks, why, despite continuing structural power, the region's trade union has entered into a class compromise with the leading employers via (a) reducing its militancy and its strategy of striking against employers to win concessions, and (b) shifting its objectives in terms of concessions sought. It speculates on the impacts of these changing class relations on the region's developmental trajectory.     

From riches to rags: organic deterioration at Star Carr

The 11,000-year old lake edge archaeological site of Star Carr in the Vale of Pickering of North Yorkshire is one of the most famous Mesolithic sites in Europe, and one of the earliest, dated to the period of climatic warming that immediately followed the final termination of the last ice age. One of the main reasons for this international importance is the richness of its organic artefacts, faunal assemblage and environmental data. However, recent investigations have demonstrated that these organic remains have severely deteriorated over the last 60 years due to the decay and acidification of the surrounding peat. This paper presents research into the effects on the bone (histological analysis using light and polarising microscopy, and Transmission Electron Microscopy, bulk collagen analysis, and amino acid analysis), antler (visual and metrical analysis, loss on ignition and Scanning Electron Microscopy) and wood (visual analysis, decay assessment tests and Scanning Electron Microscopy).     

Ancient DNA insights from the Middle Neolithic in Germany

Genetic studies of Neolithic groups in central Europe have provided insights into the demographic processes that have occurred during the initial transition to agriculture as well as in later Neolithic contexts. While distinct genetic patterns between indigenous hunter-gatherers and Neolithic farmers in Europe have been observed, it is still under discussion how the genetic diversity changed during the 5,000-year span of the Neolithic period. In order to investigate genetic patterns after the earliest farming communities, we carried out an ancient mitochondrial DNA (mtDNA) analysis of 34 individuals from Wittmar, Germany representing three different Neolithic farming groups (ca. 5,200–4,300 cal bc) including Rössen societies. Ancient DNA analysis was successful for six individuals associated with the Middle Neolithic Rössen and observed haplotypes were assigned to mtDNA haplogroups H5, HV0, U5, and K. Our results offer perspectives on the genetic composition of individuals associated with the Rössen culture at Wittmar and permit insights into genetic landscapes in central Europe at a time when regional groups first emerged during the Middle Neolithic.     

The Elusive Maya Marketplace: An Archaeological Consideration of the Evidence

The modeling of ancient Maya economies has been a dynamic area of archaeological research in the past few decades, but in most cases there has been little attention on how goods actually changed hands. Through an overview of the literature, this paper considers marketplace exchange as one mechanism of distribution. Researchers have proposed a number of physical features and artifact characteristics that may be expected in association with marketplace activity, and new methods of data collection have been offered that can be used to build a case for marketplace exchange. What remains is the challenge of developing strategies to identify ancient Maya marketplaces convincingly through archaeological excavation.
