U-Pb zircon age of the youngest magmatic activity in the High Tatra granites (Central Western Carpathians)

Detailed cathodoluminescence (CL) imaging of zircon crystals, coupled with Laser Ablation Multi-Collector Inductively Coupled Plasma Mass Spectrometry (LA-MC-ICP-MS) U-Pb zircon dating was used to develop new insights into the evolution of granitoids from the High Tatra Mountains. The zircon U-Pb results show two distinct age groups (350±5 Ma and 337±6 Ma) recorded from cores and rims domains, respectively. Obtained results point that the last magmatic activity in the Tatra granitoid intrusion occurred at ca. 330 Ma. The previously suggested age of 314 Ma reflects rather the hydrothermal activity and Pb-loss, coupled with post-magmatic shearing.     

Archaeology and in situ Preservation in Canton Thurgau,Switzerland

Canton Thurgau (approximately 1000 km²) is situated in the north-east of Switzerland. Its diverse landscape is notable for its hills, the Thur Valley, and Lake Constance. The Archaeology Department of Canton Thurgau is responsible for its archaeology. The archaeological map is quite complete and has over one thousand sites, ranging from the Palaeolithic to post-medieval periods. Particularly remarkable are the prehistoric lakeside dwellings (among them, four UNESCO World Heritage Sites) and the Roman sites, some of which have extraordinarily good conditions for preservation. The vicus Tasgetium (Eschenz) has produced one of the largest collections of Roman wooden objects and features found anywhere in the world. The Archaeology Department of Canton Thurgau conducts field surveys, excavations and scientific research. Its collections and archive are also of great importance. A major goal is to preserve the numerous sites of the canton in situ. In sensitive shore areas, where erosion (wave action, shipping etc.) threatens the exposed prehistoric cultural layers of the pile dwellings, measures are being taken to cover the areas and keep destruction at bay. These interventions are accompanied by monitoring. But numerous Roman and medieval ruins have also been restored according to the latest standards and thus prevented from gradual destruction. Thanks to zoning plans and a close working relationship with the local authorities, timely intervention can take place when sites are threatened. The results of the archaeological research are conveyed to the public and professional circles through the Museum for Archaeology and by way of popular and subject-specific publications.     

Gendered division of labour and feminisation of responsibilities in Kenya; implications for development interventions

Analysing gender roles as a social organisation element of a community is critical for understanding actors’ rationales and agency with regard to allocation and use of resources. This article discusses gender relations and how they determine development outcomes, based on a highland-lowland case-study of participants of Farmer Field Schools in Kakamega Central Sub-County (highland) and Mbeere South Sub-County (lowland). The gender relations at stake include the gendered division of labour, gender roles and intra-household power relations as expressed in access and control of resources and benefits and their implications for agricultural development. The study used mixed methods, the Harvard Analytical Framework of gender roles and draws on the Neo-Marxist position on exploitation, categorisation and institutionalisation of power relations, empowerment and the critical moments framework to discuss the results. Results in both Sub-Counties show that patriarchy prevails, determining institutional design, access and control of resources and benefits. Social positions shape capabilities and strategies of actors in decision-making and use of resources to justify gender-specific institutional arrangements. In Kakamega, men get the lion share of incomes from contracted sugarcane farming despite overburdening workloads on women, while in Mbeere, both men and women derive incomes from Khat (Catha Edulis) enterprises. However, women are expected to spend their earnings on household expenditures, which were hitherto responsibilities of men, thereby contributing to the feminisation of responsibilities. Development policies and interventions thus need to be based on an understanding of men and women’s differential access and control over resources and the institutions underpinning men and women’s bargaining power in order to adopt more effective measures to reduce gender inequalities.
