Morphology in autism spectrum disorders:local processing bias and language

We conducted a detailed study of a case of linguistic talent in the context of autism spectrum disorder, specifically Asperger syndrome. I.A. displays language strengths at the level of morphology and syntax. Yet, despite this grammar advantage, processing of figurative language and inferencing based on context presents a problem for him. The morphology advantage for I.A. is consistent with the weak central coherence (WCC) account of autism. From this account, the presence of a local processing bias is evident in the ways in which autistic individuals solve common problems, such as assessing similarities between objects and finding common patterns, and may therefore provide an advantage in some cognitive tasks compared to typical individuals. We extend the WCC account to language and provide evidence for a connection between the local processing bias and the acquisition of morphology and grammar.

The two limits debates: "Limits to Growth" and climate change

In this article we compare the current debate about global warming with the earlier discourse of Limits to Growth (LtG) of the 1970's. We are especially interested in the similarities of and differences between the two cases and therefore compare the policy challenges and lessons to be drawn. While the two debates differ on important issues, they share a technocratic orientation to public policy, and susceptibility to similar pitfalls. In both debates alarming scenarios about future catastrophes play an important role. We suggest that climate change policy discourse needs to focus more closely on the social, economic, and political dimensions of climate change, as opposed to its excessive emphasis on emission reduction targets. We also argue that an excessive faith in the market mechanisms to supply global warming mitigation technologies is problematic. In this respect, we provide a reality check regarding the political implications of emission targets and timetables and suggest how policy issues can be moved forward.

Distribution of A4 protein and neurofibrillary change in the hippocampus in Alzheimer's disease

The principal components of classical senile plaques (SP) in Alzheimer's disease (AD) appear to be A4/beta protein and paired helical filaments (PHF). A4 deposits may evolve into classical SP in brain regions vulnerable to the formation of PHF. We have investigated the diatribution of A4 deposits using an immunostain and the neurofibrillary change using the Gallyas stain in various regions of the hippocampus. This region is particularly affected in AD and also has relatively restricted inputs and outputs. In 6 patients we found a significant preponderance of A4 deposits in the adjacent parahippocampal gyrus (PHG) compared with all regions of the hippocampus. However, plaque-like clusters of PHF (Gallyas plaques) were more abundant in the subiculum while neurofibrillary tangles (NFT) were more abundant in the subiculum and region CA1 compared with the PHG and other hippocampal regions. Hence, A4 deposits appear to be concentrated in the region providing a major input into the hippocampus while the neurofibrillary changes are characteristic of the major output areas (subiculum and CA1). Hence, the data suggest that A4 formation and the neurofibrillary changes may occur in regions of the hippocampus that are connected anatomically.

Morningness-eveningness orientation and attitude change:evidence for greater systematic processing and attitude change at optimal time-of-day

This study examines the relationship between morningness-eveningness orientation and time-of day on attitude change, and tests the hypothesis that people will be more persuaded when tested at their optimal time-of-day (i.e., morning for M-types and evening for E-types) than non-optimal time-of-day (i.e., evening for M-Types and morning for E-types). Two hundred and twenty participants read a message that contained either strong vs. weak quality counter-attitudinal arguments (anti-voluntary euthanasia) in the morning (9.00. a.m.) or in the evening (7.00. p.m.). When tested at their respective optimal time-of-day (for both M- and E-types) there was a reliable difference in attitude change between the strong vs. weak messages (indicating message processing had occurred) while there was no difference between strong vs. weak messages when tested at their non-optimal time-of-day. In addition, the amount of message-congruent thinking mediated the attitude change. The results show that M- and E-types pay greater attention to and elaborate on a persuasive message at their optimal time-of-day, and this leads to increased attitude change, compared to those tested at their non-optimal time-of-day. © 2012.

Strategic groups, cognitive groups and environmental change in the UK pharmaceutical industry

This chapter explores the relationship between changes in strategy and environmental pressures within the UK Pharmaceutical Industry during a ten- year period. Two stable strategic time periods (SSTPs) were identified each of five years duration. Within each time period seven strategic groups were found but 11 out of 29 firms (37.9%) changed strategic groups membership during the period studied. The break between these two SSTPs was found to coincide with a sharp increase in the substitution of branded pharmaceuticals by cheaper parallel imports. A significant relationship was found between firms that changed groups and both their continent of origin and nationality. Firms whose home markets are more vulnerable to substitution were more likely to switch strategic groups. © 2011 Nova Science Publishers, Inc. All rights reserved.

The impact of Islamic banking on the cost efficiency and productivity change of Malaysian commercial banks

This study employs Stochastic Frontier Analysis (SFA) to analyse Malaysian commercial banks during 1996–2002, and particularly focuses on determining the impact of Islamic banking on performance. We derive both net and gross efficiency estimates, thereby demonstrating that differences in operating characteristics explain much of the difference in costs between Malaysian banks. We also decompose productivity change into efficiency, technical, and scale change using a generalized Malmquist productivity index. On average, Malaysian banks experience moderate scale economies and annual productivity change of 2.68%, with the latter driven primarily by Technical Change (TC), which has declined over time. Our gross efficiency estimates suggest that Islamic banking is associated with higher input requirements. However, our productivity estimates indicate that full-fledged Islamic banks have overcome some of these cost disadvantages with rapid TC, although this is not the case for conventional banks operating Islamic windows. Merged banks are found to have higher input usage and lower productivity change, suggesting that bank mergers have not contributed positively to bank performance. Finally, our results suggest that while the East Asian financial crisis had a short-term costreducing effect in 1998, the crisis triggered a long-lasting negative impact by increasing the volume of nonperforming loans.

Entrepreneurship in transition economies:the role of institutions and generational change

The transition economies have lower rates of entrepreneurship than are observed in most developed and developing market economies. The difference is even more marked in the countries of the former Soviet Union than those of Central and Eastern Europe. We link these differences partly with the legacy of communist planning, which needs to be replaced with formal market-supporting institutions. But many of these developments have now taken place, yet entrepreneurial activity still remains low in many places. To analyse this longer term issue, we highlight the necessarily slow pace of development of new informal institutions and the corresponding social attitudes, notably rebuilding the generalised trust. We argue that changes are even slower in the former Soviet Union than Central and Eastern Europe because communist rule was much longer, leading to a lack of institutional memory. We posit that changes in informal institutions may be therefore delayed until after full generational change.

Deindustrialisation and structural change during the post-Communist transition

The aim of this paper is to model the evolution of employment structure in post-communist economies in the broader context of deindustrialisation. The paper builds on the model of structural change developed by Rowthorn and Wells (1987). We show that the starting point of high industry sector share in total employment and its direct fall when productivity of sectors changes in favour of services can be explained in terms of this framework. Moreover, the model can also describe the phenomenon of a further expansion of the agriculture, observed in countries classified as "less consistent" in the reforms implementation. Hence, we distinguish two development paths, the efficient one, called "horizontal", and the inefficient one called "vertical". We illustrate it with empirical data, using alternative measures of structural change and patterns of structural evolutions during transition. Finally, we discuss the link between the EBRD indicators of reforms and structural change. We show that the "quality" of reforms, not the initial GDP level determines a country's development path.

UK business schools : historical contexts and future scenarios:summary report from an EBK/AIM Management Research Forum

This report begins with an analysis of the historical development of management education in Britain since 1945. It provides a context for understanding conflicting themes in current debates about business schools and examines how the different types of business school have evolved in the UK within very different education institutions. It places the current challenges faced by business schools in context, offers guidance on the strategic options available, and discusses some of the practical implications of the different paths outlined.
