Ecological Knowledge and the Regional Economy: Environmental Management in the Asesewa District of Ghana

This study examines perceptions of the environment in farming communities in the forest ecotone of Ghana. It places local knowledge within a socio-economic and historical context and argues that knowledge is continually evolving, attempting to solve existing problems and discovering new ones. It maintains that favourable conditions exist in farming communities for environmental actions and development approaches based on sustainable development, since these areas have suffered from the negative effects of degradation. However, major constraints exist within the wider political economy and policy framework, which is still locked into environmentally-hostile export-oriented production, and political models which marginalize rural people.     

Australian bicameralism as semi-parliamentarism: patterns of majority formation in 29 democracies

The article analyses the type of bicameralism we find in Australia as a distinct executive-legislative system – a hybrid between parliamentary and presidential government – which we call ‘semi-parliamentary government’. We argue that this hybrid presents an important and underappreciated alternative to pure parliamentary government as well as presidential forms of the power-separation, and that it can achieve a certain balance between competing models or visions of democracy. We specify theoretically how the semi-parliamentary separation of powers contributes to the balancing of democratic visions and propose a conceptual framework for comparing democratic visions. We use this framework to locate the Australian Commonwealth, all Australian states and 22 advanced democratic nation-states on a two-dimensional empirical map of democratic patterns for the period from 1995 to 2015.     

Toward a Comparative Measure of Climate Policy Output

Comparative policy studies face a number of methodological challenges where conceptualization of the object of comparison—policy output—is the most fundamental. On the basis of three common approaches of the study of policy output, we reconsider this widely applied concept and propose a refined measure as a function of both density (number of policy instruments) and intensity (content of policy instruments). We theoretically derive six policy‐intensity measures (objectives, scope, integration, budget, implementation, and monitoring), which are used for weighting national policy instruments on an Index of Climate Policy Activity. The article presents an empirical application of this measurement approach. Focusing on national climate policy instruments in the energy production sector in Austria, Germany, and the United Kingdom, we investigate changes in the countries' policy portfolios from 1998 to 2010. The article demonstrates that our Index of Climate Policy Activity provides a reliable and valid measurement for national policy output that can be applied for comparative analyses of policy output.     

Flake scar patterns of Clovis points analyzed with a new digital morphometrics approach: evidence for direct transmission of technological knowledge across early North America

Clovis points are the principal diagnostic artifacts of a Clovis complex that spread across North America between ca. 11,050–10,800 radiocarbon years before present. Clovis may be the best documented Paleoamerican culture in North America, but much remains to be learned about the movement and interactions of Clovis peoples. Similarities among Clovis points from geographically diverse locations have led some researchers to suggest that a uniform projectile point technology existed across North America during Clovis times. Others have rejected this idea, proposing local and independent technological adaptations to different regional environments. To investigate these ideas, we used digital morphometrics to analyze 50 Clovis points from nine different contexts. First, 3D surface models of the points were created with a portable laser scanner. Next, these models were digitally cross-sectioned through both faces, yielding two-dimensional isoheight contours of flake scar patterns that reflect the original reduction techniques used to shape the projectile points. In the final step, the contours were transformed with elliptic Fourier analysis into Fourier coefficient series, and patterns of variation and symmetry were explored with principal components analysis. When compared to modern Clovis point replicas made by an expert knapper, the flake scar contours of the ancient Clovis points showed little morphological variation and a large degree of bifacial symmetry. Our results support the existence of a widespread standardized “Clovis” knapping technique, most likely transmitted through direct interaction between knappers from different groups.     

The Sheep Project (1): determining skeletal growth,timing of epiphyseal fusion and morphometric variation in unimproved Shetland sheep of known age,sex, castration status and nutrition

The Sheep Project was designed to investigate the effects of castration, breeding age and nutritional plane on bone growth, epiphyseal fusion, tooth eruption and tooth wear in sheep. The project investigates a population of 356 unimproved Shetland sheep skeletons evenly distributed between females bred at different ages, males and castrates, raised on either high or low nutritional planes. This first instalment focuses on two aspects of our larger study, namely bone growth and epiphyseal fusion as affected by sex, castration and nutrition. Nutrition, sex and castration are shown to influence bone growth in ways that are often element-dependant and not consistent through time. We demonstrate that metric variability (variance) is strongest in males, with little difference between females and castrates, and that, in our sample, nutrition has little influence on variance in any sex cohort. Of importance to the development of models of past animal management this study demonstrates that the standard epiphyseal fusion ranges used by zooarchaeologists are too narrow in most instances and do not account for the large variation between sexes or the lesser variation between planes of nutrition. We recommend methods for recognizing castration and the presence of more than one sheep breed, or type, within the zooarchaeological record.     

Die ‘Krüppelfürsorge’ in der Weimarer Republik. Zwischen eigenem Standpunkt und diskursiver Anschlussfähigkeit an eugenische Argumentationsstrukturen

The ‘Krüppelfürsorge’ during the Weimar Republic. Oscillating between an Own Position and the Adoption of Eugenic Arguments. This article examines the discourse about physical disability led by the German ‘Krüppelfürsor‐ge’. It deals with the exhibition GeSoLei (Gesundheitspflege, soziale Fürsorge and Leibesübungen), which took place in Düsseldorf in 1926. The GeSoLei was one of the most popular platforms of the healthy and aesthetic body in the 1920s. It stood in the context of the German ‘national recovery’ after World War I and collected all types of medical, social and athletic professionals to expose their work to a broader audience. Also representatives of the so called ‘Krüppelfürsorge’ presented themselves and at the same time their perspective on people with physical disabilities on this exhibition. The article points out the ambivalent character of their perspective and shows the mixture of including and excluding people with physical disabilities, which was typical for the view of the ‘Krüppelfürsorge’. It demonstrates that the ‘Krüppelfürsorger’ on the one hand were quite progressive towards people with disabilities, but on the other hand showed a striking openness towards eugenic values.
