Gender Boundaries

In post-Socialist countries, cross-border labour migration has become a common individual and family livelihood strategy. The paper is based on the analysis of semi-structured interviews conducted with two ethnic Hungarian women whose lives have been significantly reshaped by cross-border migration. Focusing on the interplay of gender and cross-border migration, our aim is to reveal how gender roles and boundaries are reinforced and repositioned by labour migration in the post-socialist context where both the socialist dual-earner model and conventional ideas of family and gender roles simultaneously prevail. We found that cross-border migration challenged these women to pursue diverse strategies to balance their roles of breadwinner, wife, and mother responsible for reproductive work. Nevertheless, the boundaries between female and male work or status were neither discursively nor in practice transgressed. Thus, the effect of cross-border migration on altering gender boundaries in post-socialist peripheries is limited.

Abstract: In northern Brazilian Amazon, the crops, savannahs and rainforests form a complex landscape where land use and land cover (LULC) mapping is difficult. Here, data from the Operational Land Imager (OLI)/Landsat-8 and Phased Array type L-band Synthetic Aperture Radar (PALSAR-2)/ALOS-2 were combined for mapping 17 LULC classes using Random Forest (RF) during the dry season. The potential thematic accuracy of each dataset was assessed and compared with results of the hybrid classification from both datasets. The results showed that the combination of PALSAR-2 HH/HV amplitudes with the reflectance of the six OLI bands produced an overall accuracy of 83% and a Kappa of 0.81, which represented an improvement of 6% in relation to the RF classification derived solely from OLI data. The RF models using OLI multispectral metrics performed better than RF models using PALSAR-2 L-band dual polarization attributes. However, the major contribution of PALSAR-2 in the savannahs was to discriminate low biomass classes such as savannah grassland and wooded savannah.

Unscheduled Flows

Abstract Unscheduled power flows are a serious problem for the Central and Eastern Europe (CEE) region. One method of reducing these undesirable flows relies on the use of phase shifting transformers (PSTs). This paper presents how the installation of PSTs on the Polish-German and Czech-German borders affects cross-border power flows in the CEE region, as well as interactions between these devices. The essential parameters proposed for PSTs are based on the effects arising from the application of PSTs on the border between Poland and Germany. The results demonstrate that the use of PSTs in the CEE region can provide effective control of active power flows in tie-lines and significantly reduce unscheduled flows. However, the operation of these devices must be coordinated in order to achieve maximum controllability and to guarantee the secure operation of the interconnected systems.

AbstractExtending the Landscape Pattern Metric (LPM) model analysis in Smith et al. (2001) into a LPM decision model, decadal scale prediction of fecal coliform compromised South Carolina watersheds is developed. The model’s parameter variability identifies the greatest contributors to a compromised watershed’s prediction. The complete set of model parameters include Land Cover Land Use (LCLU) & slope,along stream proportion, Fourier Metric of Fragmentation (FMF), Fourier Metric of Proportion (FMP), and Least Squares Fourier Transform Fractal Dimension (LsFT). The 1992 National Land Cover Data (NLCD) Land Cover Land Use (LCLU) within fecal coliform compromised watersheds is used to train the model parameters, and the 2001 NLCD LCLU is used to test the LPM model. The most significant model parameters arealong stream bare rock LsFT,FMF between urban/recreational grasses and evergreen forests, andFMF between deciduous forests and high density residential areas. These metrics contribute significantly more than the bestproportiondescriptor:proportion of urban/recreational grasses. In training, the proposed model correctly identified 92 % of the compromised watersheds; while the Smith et al. (2001) model 94 % of the compromised watersheds were correctly identified. This study reveals the ability of Fourier metrics to interpret ecological processes, and the need for more appropriate landscape level models.

The Way

An important assumption of many environmental decisions is that some patterns or combinations of land cover are optimal or more preferable to others. Management plans fre quently seek to change the structure of a landscape to realise particular management goals, because it is recognized that the spatial arrangement of elements in a land cover mosaic control the ecological processes which operate within it. This study reviews some of the tools available to those who need to describe and understand the spatial structure of landscapes. In particular, it examines the way in which quantitative measures, or indices, can be used and what contri bution they might make to the management of forested landscapes in the UK. The paper dis cusses the way in which the different landscape indices can be used to assess the spatial impli cations of the various design guidelines that have been proposd to promote sustainable forms of forestry. It is concluded that while progress has been made in the development of a range of landscape pattern measures, and in our understanding of the factors constraining their use, there is a pressing need for further research into the relationship between landscape pattern and ecological process.
