The Role of Structural Position in L2 Phonological Acquisition: Evidence from English Learners of Spanish as L2

FOREIGN LANGUAGE ANNALS, Issue 2 2008
Gabriela Vokic
Abstract: In this pilot study, the speech of 12 adult native speakers of English with intermediate to intermediate-high proficiency in Spanish as a second language (L2) was analyzed to determine whether L2 learners rely on distributional information in the process of L2 speech learning and if so, if similar or dissimilar distributional patterns of sounds are more easily acquired. The parameter for (dis)similarity was set around the notion of structural position in combination with native language (L1) and L2 phonemic inventories. The results show that the subjects were consistently more successful in producing the phonemes with overlapping distributional patterns in L1 and L2 than phonemes whose distribution differed in L1 and L2 as well as novel L2 contrasts.

Structural position of the Seba eclogite unit in the Sambagawa Belt: Supporting evidence for an eclogite nappe

ISLAND ARC, Issue 2 2002
Article first published online: 4 JUL 200, Mutsuki Aoya
Abstract Eclogite-bearing units in the Sambagawa Metamorphic Belt have long been considered tectonic blocks that have disparate tectonic and metamorphic histories that are distinct from each other and from the major non-eclogitic Sambagawa schists. However, recent studies have shown that eclogite facies metamorphism of the Seba eclogite unit is related to the subduction event that caused the metamorphism of the non-eclogitic Sambagawa schist. New structural data further show that the Seba eclogite unit, which appears to be isolated from the other eclogite units, is in fact in structural continuity with them, occupying the highest structural levels in the Sambagawa Belt. This suggests that eclogitic metamorphism of the other eclogite units is also related to the Sambagawa subduction event. It is, therefore, possible that all eclogite units in the Sambagawa Belt constitute a single coherent unit, the eclogite nappe, members of which underwent the same eclogitic metamorphism related to the Sambagawa subduction event.

THE EVOLUTION OF A MODEL TRAP IN THE CENTRAL APENNINES, ITALY: FRACTURE PATTERNS, FAULT REACTIVATION AND DEVELOPMENT OF CATACLASTIC ROCKS IN CARBONATES AT THE NARNI ANTICLINE

JOURNAL OF PETROLEUM GEOLOGY, Issue 2 2001
F. Storti
Recent hydrocarbon discoveries in the Southern Apennines of Italy have focussed attention on the importance of studying fracturing and cataclasis in carbonate rocks because of their fundamental impact on reservoir permeability and connectivity. The Narni Anticline in the central Apennines consists of a stack of easterly-verging carbonate thrust sheets compartmentalized by extensional and strike-slip fault zones. The structure provides afield analogue for studying the evolution of superimposed fold- and fault-related fractures in carbonate reservoir rocks. The fracture pattern at the Narni Anticline developed as a result of three mechanisms: (a) layer-parallel shortening predating folding and faulting; (b) thrust-related folding and further thrust breakthrough; and (c) extensional and strike-slip faulting. Along-strike (longitudinal) fractures developed during progressive rollover fault-propagation folding, and their intensity depends on the precise structural position within the fold: fracture intensity is high in the forelimb and low in the crest. The 3-D architecture of the mechanical anisotropy associated with thrusting, folding, and related fracturing constrained the location and geometry of subsequent extensional and strike-slip faulting. The superimposition in damage zones of a fault-related cleavage on the pre-existing fracture pattern, which is associated with layer-parallel shortening and thrust-related folding, resulted in rock fragmentation and comminution, and the development of cataclastic bands. The evolution of fracturing in the Narni Anticline, its role in constraining thrust breakthrough trajectories and the location of extensional and strike-slip faults, and the final development of low-permeability cataclastic bands, will be relevant to studies of known oilfields in the Southern Apennines, as well as for future exploration.

The illusion of progress in nursing

NURSING PHILOSOPHY, Issue 1 2001
Elizabeth A. Herdman RN Ba Social Science PhD
Abstract The notion that history is a record of continuous improvement has come to dominate the Western view of the world. This paper examines how nursing has embraced this ,Enlightenment project' and continues to be guided by a faith in ,history as progress' despite the fact that its structural position remains one of subordination and struggle. Faith in progress is manifested in nursing historiography and contemporary nursing literature, in the basic tenet of nursing orthodoxy, that professionalization is both inevitable and desirable, in the alignment of nursing with medical science and technology and the belief that Western nursing is the model for nursing world wide. It is argued that this uncritical faith in a continuously improving future has obscured nursing's vision for the future and rendered it powerless in the face of rapid global economic and social change.

Understanding public attitudes towards Social Security

INTERNATIONAL JOURNAL OF SOCIAL WELFARE, Issue 2 2006
Philip Yang
There has been very little research on why individuals hold different attitudes toward Social Security. In this article we integrate social location theory and political predisposition theory to provide a framework of explanation and test these theories using a unique sample from the 1998 General Social Survey. Our multivariate results reveal that social structural positions along the lines of race, gender, class and age play a more important role than political predispositions in explain-ing individual differences in support for the current Social Security system against privatisation. Political party affiliation also partly contributes to variation in support for Social Security, but political ideology does not have a significant effect. Our results suggest that with regard to support for Social Security, primary consideration must rest on social structural positions. Racial minorities, women, the poor and the elderly tend to dislike a drastic change in the current Social Security system, and Social Security reform ought to pay attention to their concerns. Our robust finding of a positive relationship between age and support for Social Security also challenges much of the established knowledge, pointing to an intergenerational discord over Social Security. It is also important to differentiate among social welfare programmes in order to uncover the real determinants of public attitudes towards them. [source]
