Farmland abandonment has important impacts on biodiversity and ecosystem recovery, as well as food security and rural sustainable development. Due to rapid urbanization and industrialization, farmland abandonment has become an increasingly important problem in many countries, particularly in China. To promote sustainable land-use management and environmental sustainability, it is important to u...

Interpretation of archaeological sites with predominantly freshwater fish and reptile remains has been impeded by lack of documentation of how humans process such vertebrates, of bone modifications resulting from such handling, and of physical characteristics of sites produced by these activities. We report on 19 contemporary foraging camps on the shore of Lake Turkana, Kenya, with the creation...

This study examines the abandonment of organizational practices. We argue that firm choices in implementing practices affect how firms experience a practice and their subsequent likelihood of abandonment. We focus on utilization of the practice and staffing, i.e. career backgrounds of managers, as two important implementation choices that firms make. The findings demonstrate that practice utili...

OBJECT Although infant abandonment is a historical problem, we know remarkably little about the conditions or effects of abandonment to guide evidence driven policies. This paper briefly reviews the existing international evidence base with reference to potential mental health considerations before mapping current UK guidelines and procedures, and available incidence data. Limitations arising f...

This paper uses remote sensing data from 1989 to 2000 to examine the impacts of price liberalization, land tenure, and biophysical characteristics on farmland abandonment in the border region of Poland, Slovakia, and Ukraine. Using regression analysis and matching estimators, we find that differences in biophysical characteristics, rather than in tenure systems, best explain the variation in ab...

The 1993 flood of the Missouri River led to the abandonment of agriculture on considerable land in the floodplain. This abandonment led to a restoration opportunity for the U.S. Federal Government, purchasing those lands being sold by farmers. Restoration of this floodplain is complicated, however, by an imperfect understanding of its past environmental and vegetative conditions. We examined en...

Effects of passive restoration of mountain rivers on the organisms inhabiting exposed riverine sediments are considerably less understood than those concerning aquatic biota. Thus, the effects of a recovery of the Raba River after abandonment of maintenance of its channelization scheme on ground beetle (Coleoptera: Carabidae) communities were investigated by comparing 6 unmanaged cross-sections...

The subject of ‘orphan works’ and ‘abandonware’ is gaining legal attention lately. It concerns the status of copyrighted works which are still within the term of protection but are no longer commercially available to the public. This paper examines the question of orphan works and abandonware from a law and economics perspective. Orphan works and abandonware are classified into five types depen...

Amount, stability, and distribution of black carbon (BC) were studied at four sites of a large peatland (“Witzwil”) formerly used as a disposal for combustion residues from households to derive BC displacement rates in the profile. Possible artefacts from thermal oxidation with Differential Scanning Calorimetry (DSC) on BC quantification of C-rich deposits were inferred by choosing three sites ...
