BACKGROUND This study examined associations between anxiety and work-related outcomes in an anxiety disorders clinic population, examining both pretreatment links and the impact of anxiety change over 12 weeks of treatment on work outcomes. Four validated instruments were used to also allow examination of their psychometric properties, with the goal of improving measurement of work-related qual...

This paper proposes several improvements to the correlationbased location features recently used in meeting speaker diarization. A speech-specific alternative to the generalized cross correlation phase transform (GCC-PHAT) algorithm is tested and shown to provide equal or better results without noise reduction or continuity-enforcing smoothing. The limitations of a single correlation reference ...

Runtime techniques bring new promises of accuracy and flexibility in enforcing security policies. While static security enforcement was previously studied and classified, this work is the first to survey the state of the art on runtime security enforcement. Our purpose is to encourage a better understanding of limitations and advantages of enforcement techniques and their implementations. We cl...

This paper introduces a new hyperspectral unmixing method called Dependent Component Analysis (DECA). This method decomposes a hyperspectral image into a collection of reflectance (or radiance) spectra of the materials present in the scene (endmember signatures) and the corresponding abundance fractions at each pixel. DECA models the abundance fractions as mixtures of Dirichlet densities, thus ...

Reputation-management, as proposed for dynamic and open systems aims to provide mechanism for analysing the behaviour of agents, and to distribute this information so that the impact of the actions of those acting against the interests of a community can be limited. We study the assumptions that underpin this decisionmaking role for reputation-management and highlight its limitations with regar...

We propose a novel approach to the semantics of quantified μ-calculi, considering models where states are algebras; the evolution relation is given by a counterpart relation (a family of partial homomorphisms), allowing for the creation, deletion, and merging of components; and formulas are interpreted over sets of state assignments (families of substitutions, associating formula variables to s...

There is great need and potential for traditional transaction support in a mobile computing environment. However, owing to the inherent limitations of mobile computing, we need to augment the well-developed techniques of Database Management Systems with new approaches. In this paper, we focus on the challenge of assuring data consistency. Our approach of localization is to reformulate global co...

substitution management planning, as one of the important issues in manpower planning, is referred to as a process of filling the gaps and fulfilling the needs of very crutial and key elements of organization in managerial levels. meeting the needs by means of using external and internal manpower of the organization seems to be rational. however, it has some advantages and disadvantages. this p...

BACKGROUND Health impairments can result in disability and changed work productivity imposing considerable costs for the employee, employer and society as a whole. A large number of instruments exist to measure health-related productivity changes; however their methodological quality remains unclear. This systematic review critically appraised the measurement properties in generic self-reported...
