In-depth analysis of network security vulnerability must consider attacker exploits not just in isolation, but also in combination. The general approach to this problem is to compute attack paths (combinations of exploits), from which one can decide whether a given set of network hardening measures guarantees the safety of given critical resources. We go beyond attack paths to compute actual se...

This paper describes an error detection mechanism which helps in validation of dependency treebank annotation. Consistency in treebank annotation is a must for making data as errorfree as possible and for assuring the usefulness of treebank. This work is aimed at ensuring this consistency and to make the task of validation cost effective by detecting major errors induced during completely manua...

We present experiments with a dependency parsing model defined on rich factors. Our model represents dependency trees with factors that include three types of relations between the tokens of a dependency and their children. We extend the projective parsing algorithm of Eisner (1996) for our case, and train models using the averaged perceptron. Our experiments show that considering higher-order ...

This paper presents a large-scale evaluation study of dependency-based distributional semantic models. We evaluate dependencyfiltered and dependency-structured DSMs in a number of standard semantic similarity tasks, systematically exploring their parameter space in order to give them a “fair shot” against window-based models. Our results show that properly tuned window-based DSMs still outperfo...

Powerholders may engage in two stereotyping processes: (a) by default, inattention to stereotype-inconsistent information, due to lack of dependency, and (b) by design, effortful attention to stereotype-consistent information, due to explicit control. Study 1 manipulated control (not dependency) over internship applicants; powerful decision-makers increased attention to stereotypic attributes, ...

The overall aim of this study is to empirically investigate the cost structure of a management agreement type agri-environmental instrument and to identify factors for cost variation over space and time. We control for the actual level of compliance by using compliance weighted average scheme cost ratios. Beside technological and economic performance measures, we also incorporate risk proxies. ...

Mapping species composition is a focus of the wetland science community as this information will substantially enhance assessment and monitoring abilities. Hyperspectral remote sensing has been utilized as a cost-efficient approach. While hyperspectral instruments can record hundreds of contiguous narrow bands, much of the data are redundant and/or provide no increase in utility for distinguish...

BACKGROUND Carer burden is high during First Episode Psychosis (FEP) and evidence suggests that this is a predictor of poor long-term outcome. However our understanding of factors associated with higher burden is poor. We propose that carers' cultural backgrounds and health belief models will influence their perceived burden of care, over and above that explained by severity of illness. METHO...

Laser forming of sheet metal offers the advantages of requiring no hard tooling and thus reduced cost and increased flexibility. It also enables forming of some materials and shapes that are not possible now. In single-axis laser bending of plates, the bending edge is found to be somewhat curved and the bending angle varies along the laser-scanning path. These phenomena are termed edge effects,...

The onset of bathing disability among older people is critical for a decline in functioning and has implications for both the individuals' quality of life and societal costs. The aim of this study was to evaluate long-term cost effectiveness of an intervention targeting bathing disability among older people. For hypothetical cohorts of community-dwelling older people with bathing disability, tr...
