We present a phrasal inversion transduction grammar as an alternative to joint phrasal translation models. This syntactic model is similar to its flatstring phrasal predecessors, but admits polynomial-time algorithms for Viterbi alignment and EM training. We demonstrate that the consistency constraints that allow flat phrasal models to scale also help ITG algorithms, producing an 80-times faste...

We present a mechanism able to show intrinsic bistable behaviour involving single Y b ions embedded into bromide lattices, in which intrinsic optical bistability (IOB) has been observed. The mechanism is based on the experimentally found coupling between the Y b ion and the totally symmetric local mode of vibration of the [Y bBr6] 3− coordination unit. The model reproduces the IOB observed in C...

according to the resource based attitude, the capabilities of information systems improve firms’ performance and competitive advantages through three ways: 1) inside-outside capabilities, 2) outside-inside capabilities and 3) spanning capabilities. because of the importance of systematic study on the relationship between these capabilities and firms’ performance this paper was aimed at investig...

The objective of this investigation was to identify nurses' practice in heath audit. The hermeneutic-dialectic method was used for the analysis. The study was performed in three loci: the internal audit service of a hospital; the external audit service of a private health service buyer, and the state audit service of the public health system (SUS, acronym in Portuguese for Sistema Unico de Saúd...
