Roughly speaking, the compositional semantics analysis of natural language consists in mapping a sentence to a logical formula which depicts its meaning. To do so, a lexicon endow each word with a partial formula (a λ-term over the base type t for propositions and e for individuals), and the (binary) parse tree of the sentence specifies for each node which subtree is the function and which one ...

In this article, we study the school bus routing and scheduling problem with transfers arising in the field of nonperiodic public transportation systems. It deals with the transportation of pupils from home to their school in the morning taking the possibility that pupils may change buses into account. Allowing transfers has several consequences. On the one hand, it allows more flexibility in t...

The paper is focused on classes of lexical units which arise as a result of derivational processes – word formation and semantic transfers, acting either in isolation or together, on the basis of common semantic foundations that bind targets and sources of derivation. The lexical items which constitute the classes under study vary in their denotative characteristics and due to their categ...

BACKGROUND Little is known about inter-facility patient transfers in populations. In 2003, detailed information about inter-facility patient transfers began to be systematically collected in Ontario. METHODOLOGY The authors undertook a descriptive examination of inter-facility patient transfers using a newly created population-based information system. RESULTS Approximately 1,000 inter-faci...

BACKGROUND Intergenerational transfer patterns in sub-Saharan Africa are poorly understood, despite the alleged importance of support networks to ameliorate the complex implications of the HIV/AIDS epidemic for families. OBJECTIVE There is a considerable need for research on intergenerational support networks and transfers to better understand the mechanisms through which extended families co...
