The productivity-driven Mortensen-Pissarides model predicts that labor productivity, defined as the ratio of output to employment, is strongly correlated with employment, unemployment, vacancies and wages whereas these correlations were argued to be much weaker in the data, especially since the mid 1980s. We first document that the size of these discrepancies between the data and the model beco...

Heart-related pathologies are among the most frequent health problems in western society. Symptoms that point towards cardiovascular diseases are usually diagnosed with angiographies, which allow the medical expert to observe the bloodflow in the coronary arteries and detect severe narrowing (stenosis). According to the severity, extension, and location of these narrowings, the expert pronounce...

The current study addresses the changing use of audio and visual cues in audio-visual speech perception during adulthood by testing young and middle-aged adults using stimuli with incongruent audio-visual consonants. Young adults gave more audio responses and fewer visual responses than middle-aged adults. Results show no age differences in auditory or visual sensitivity. The discrepancy in use...

Article history: Received 9 February 2011 Available online 8 July 2011 The current study investigated the role of approach and avoidance motives for unemployed job search behavior. Two approach motives (employment and PJ-fit) and two avoidance motives (low-expectation and low-interest) were distinguished. Antecedents and consequences of these motives were examined using a sample of 303 unemploy...

The current study examined whether preschoolers who are low achievers (LA) on mathematical tasks benefit more from a training programme that focuses on magnitude comparisons or ANS abilities (PLUS games) compared to games that target symbolic knowledge (DIGIT games). Twenty-four preschoolers played PLUS games and 21 children played DIGIT games 3 times per week for 5 weeks. Performance scores we...

Climatic data for the Continental United States for the 1850’s and 1860’s are compared with the currently valid normals. In the eastern half of the United States, these two decades continue the cooler and somewhat wetter character found in an earlier investigation, while in the western half, a distinctly warmer and decisively wetter climate existed in the mid-19th century, as compared to the co...

2 Acknowledgements I would like to thank my advisor, Karen Faulk, for all her help throughout the process of researching, writing, and refining this thesis. This project would not have been possible without her guidance and patience, and I am incredibly grateful she has been my advisor and mentor over the last year. I would also like to thank the History Department and the Global Studies facult...

Increasing user engagement is constant challenge for Intelligent Tutoring Systems researchers. A current trend in the ITS field is to increase engagement of proven learning systems by integrating them within games, or adding in game like components. Incorporating proven learning methods within a game based environment is expected to add to the overall experience without detracting from the orig...

The purpose of this note is to point out some very elementary examples of special Lagrangian tori in certain Calabi-Yau manifolds that occur as hypersurfaces in complex projective space. All of these are constructed as real slices of smooth hypersurfaces defined over the reals. This method of constructing special Lagrangian submanifolds is, of course, well known. What does not appear to be in t...

It has been recently discussed in linguistics that the notion of identity in the task of coreference resolution is of continuous nature, ranging from “complete” identity to non-identity. The current paper confronts this idea with experimental data for Polish, resulting in a new approach to the notion of identity. It extends the definition of coreference with speaker/recipient relation, believed...
