NS Branes in Type I Theory
We consider novel nonperturbative effects of type I theories compactified on
singular ALE spaces obtained by adding NS branes. Such effects include a
description of small instantons at singularities.Comment: 6 pages, Harvmac.tex, updated referenc
Children's naming and word-finding difficulties: descriptions and explanations
Purpose: There are a substantial minority of children for whom lexical retrieval problems impede the normal pattern of language development and use. These problems include accurately producing the correct word even when the word?s meaning is understood; such children are often referred to as having word-finding difficulties (WFDs). This review examines the nature of naming and lexical retrieval difficulties in these and other groups of children. Method: A review of the relevant literature on lexical access difficulties in children with word finding difficulties was conducted. Studies were examined in the terms of population parameters and comparison groups included in the study. Results and Conclusions: Most discussions of the cognitive processes causing lexical retrieval difficulties have referred to semantics, phonology and processing speed. It is argued that our understanding of these topics will be further advanced by the use of appropriate methodology to test developmental models that both identify the processes in successfully performing different lexical retrieval tasks and more precisely locating the difficulties experienced by children with such tasks
The fundamental challenge: human and organisational factors in an ERP implementation
Organisations encounter obstacles when implementing ERP systems. This paper intends to explore some of the problems that occur throughout the implementation of an ERP system. Using a combination of the work of Markus et al (2001) and Kim et al (2005), a framework is constructed of Human and Organisational and Technical problems in ERP Implementations during the project phase. Drawing on empirical evidences from a UK furniture manufacturer, this study then discusses and analyses each problem identified in the framework and its affect on the implementation of their ERP system. The findings of this paper reveal that the fundamental challenge of ERP implementation is not technology but organisational and human problems, which, if not properly comprehended and addressed, can lead to ERP failure. Understanding that organisational and human issues are extremely important will encourage practitioners to address these problems and succeed in their ERP system implementations
Calculation of Nonperturbative Terms in Open String Models
Nonperturbative corrections in type II string theory corresponding to Riemann
surfaces with one boundary are calculated in several noncompact geometries of
desingularized orbifolds. One of these models has a complicated phase structure
which is explored. A general condition for integrality of the numerical
invariants is discussed
The relation between naming and literacy in children with word-finding difficulties
Difficulties with picture naming tasks are associated with literacy problems. Children with dyslexia, when given naming tasks, are slower to produce words and have a higher proportion of errors (Wolf and Bowers, 1999). However, little is known about the relation between literacy and naming in other populations. This study investigates this relation in 20 children (aged 6:6 â 7:11) with word-finding difficulties (WFDs). The children in our sample performed very poorly on assessments of naming, but unlike children with dyslexia, were found to have decoding and spelling abilities within the normal range. In addition, their abilities on phonological awareness tasks were at a similar level to their decoding abilities. In contrast, performance on reading comprehension and language comprehension was significantly worse than for decoding, spelling and rhyme awareness. The implications of our findings for models concerned with understanding the relation between naming speed and literacy abilities are discussed
