While organisational collaborations are increasingly common they often fail. More effective design of collaborations should be facilitated by improved understanding of the relationships created. It is suggested that while the most commonly used theoretical lens is transaction cost economics it might not be the most appropriate. Resource dependency theory is proposed as an alternative since it a...

Background: Attention deficit hyperactivity disorder and conduct disorder are among relatively prevalent disorders during childhood and adolescence. Considering the negative impact of the parents' drug dependency and bipolar disorder, the present study aimed to determine the prevalence of ADHD and conduct disorder in children of drug-dependent and bipolar parents. Methods: In this case-control ...

This dissertation in a broad sense focuses on understanding the fundamental aspects of building a large-scale information integration system that can answer complex queries over a large number of heterogeneous Internet data sources. Among many challenges in achieving this goal, we focus on two key issues: efficient query processing and schema matching. Most of the data the integration system pr...

to be able to reach the level of ultimate attainment in the second language, learners need to acquire not only the grammar of the l2 but also the language processing mechanisms involved in the comprehension of sentences in real time. contrary to its importance, very little is known yet about online l2 processing. this study examines whether advanced iranian learners of english reactivate disloc...

a 21-year old man with cervical spinal cord damage due to diving was admitted in the icu. tracheostomy was performed due to prolonged mechanical ventilation. left lung atelectasis happened frequently. because of the difficulty of bronchoscopy and failing of recruitment, using a double lumen, two tracheal tubes were guided into the left and right lungs through the tracheostomy stoma site. after ...

Multi-resolution representation of simulated entities is considered essential for a growing portion of distributed simulations. Heretofore, modelers have represented entites at just one level of resolution, or have represented concurrent representations in an inconsistent mannel: We address the question of the cost of maintaining multiple, concurrent representations. We present a brief overview...

We propose a non-local cost aggregation algorithm to recognize the identity of face and person tracks in a TV-series. In our approach, the fundamental element for identification is a track node, which is built on top of face and person tracks. Track nodes with temporal dependency are grouped into a knot. These knots then serve as the basic units in the construction of a k-knot graph for explori...

A number of researchers have presented evidence that the hardest constraint satisfaction problems tend to arise near the \crossover" point, where around half the problems have solutions. Two recent papers , however, argue that while this is true of the median search cost, the mean search cost has an entirely diierent behavior. The mean search cost appears to be dominated by a relatively small n...
