Avantages comparatifs et dynamiques de spécialisation : le cas des pays africains.
2021
In this thesis we analyze the mechanisms linking trade openness and industrialization patterns. We are particularly interested in developing countries, especially those belonging to the African continent, because of their particular form of production specialization— essentially based on agricultural and mining products. Our goal is to better understand the evolution of these forms of specialization in order to identify possible paths of industrial development. Chapter 1 provides a comprehensive overview of the literature on the theoretical determinants of international specialization and pays particular attention to theories emphasizing a dynamic view of comparative advantage. This chapter…
Dynamic Analysis of sectorial Specialization and Agglomeration Economies in the Sicilian Local Labour Systems
2008
This paper examines the spatial dependence among productive specialization, variety of the economic environment and knowledge spillovers. With the aim of identifying localization benefits in a particular area, some aspects of business settling are compared with trends in the development of economic activities and, particularly, with agglomeration process of the firms. On the basis of the model proposed by Ellison and Glaeser (1997) it is possible identifying an “agglomerate space” that is to say a “continuous set of territorial areas specialized in a specific sector one of which, at least, proves to be provided with a level of specialization noticeably exceeding the expected value under the…
Children show right-lateralized effects of spoken word-form learning
2017
It is commonly thought that phonological learning is different in young children compared to adults, possibly due to the speech processing system not yet having reached full native-language specialization. However, the neurocognitive mechanisms of phonological learning in children are poorly understood. We employed magnetoencephalography (MEG) to track cortical correlates of incidental learning of meaningless word forms over two days as 6±8-year-olds overtly repeated them. Native (Finnish) pseudowords were compared with words of foreign sound structure (Korean) to investigate whether the cortical learning effects would be more dependent on previous proficiency in the language rather than ma…
Change detection to tone pairs during the first year of life – Predictive longitudinal relationships for EEG-based source and time-frequency measures
2019
Abstract Brain responses related to auditory processing show large changes throughout infancy and childhood with some evidence that the two hemispheres might mature at different rates. Differing rates of hemispheric maturation could be linked to the proposed functional specialization of the hemispheres in which the left auditory cortex engages in analysis of precise timing information whereas the right auditory cortex focuses on analysis of sound frequency. Here the auditory change detection process for rapidly presented tone-pairs was examined in a longitudinal sample of infants at the age of 6 and 12 months using EEG. The ERP response related to change detection of a frequency contrast, i…
Transient topographical amnesia and cingulate cortex damage: A case report
1996
Transient topographical amnesia (TTA) is the temporary inability to find one's way in familiar or unfamiliar surroundings due to the inability to use well known environmental landmarks for route finding. The syndrome has not been described as having any obvious aetiology and has been thought to be caused by a vascular deficit in right hemispheric structures which are crucial for topographic recognition, i.e. parietal association and parahippocampal cortex. The patient described in the present study complained of several critical episodes of TTA and tonic rigidity of the left limbs. Neuropsychological assessment was normal except for a deficit in spatial memory tasks. Magnetic resonance (MR)…
A longitudinal study on the information needs and preferences of patients after an acute coronary syndrome.
2016
Background Research has shown that the provision of pertinent health information to patients with cardiovascular disease is associated with better adherence to medical prescriptions, behavioral changes, and enhanced perception of control over the disease. Yet there is no clear knowledge on how to improve information pertinence. Identifying and meeting the information needs of patients and their preferences for sources of information is pivotal to developing patient-led services. This prospective, observational study was aimed at exploring the information needs and perceived relevance of different information sources for patients during the twenty-four months following an acute coronary synd…
Contrasting parental roles shape sex differences in poison frog space use but not navigational performance
2022
Sex differences in vertebrate spatial abilities are typically interpreted under the adaptive specialization hypothesis, which posits that male reproductive success is linked to larger home ranges and better navigational skills. The androgen spillover hypothesis counters that enhanced male spatial performance may be a byproduct of higher androgen levels. Animal groups that include species where females are expected to outperform males based on life-history traits are key for disentangling these hypotheses. We investigated the association between sex differences in reproductive strategies, spatial behavior, and androgen levels in three species of poison frogs. We tracked individuals in natura…
Zooming into firm’s location, capabilities and innovation performance: does agglomeration foster incremental or radical innovation?
2022
[EN] This study answers the question on whether areas of agglomeration or high industry specialization constitute supportive prone-to-innovation environments for the generation of radical innovation. By drawing on the CIS distinction between incremental vs radical innovation, we disentangle the effect of industry specialization on the occurrence of radical innovations, a phenomenon mostly overlooked. By analysing a large dataset of 3,602 firms from CIS and other geographic datasets, results show that a firm's location in high industry specialization areas primarily trims incremental but not radical innovation. Firms' internal knowledge bases do matter more for radical innovation to occur, r…
Micrometer-resolution reconstruction and analysis of whole mouse brain vasculature by synchrotron-based phase-contrast tomographic microscopy
2021
AbstractNervous tissue metabolism is mainly supported by the dense thread of blood vessels which mainly provides fast supplies of oxygen and glucose. Recently, the supplying role of the brain vascular system has been examined in major neurological conditions such as the Alzheimer’s and Parkinson’s diseases. However, to date, fast and reliable methods for the fine level microstructural extraction of whole brain vascular systems are still unavailable. We present a methodological framework suitable for reconstruction of the whole mouse brain cerebral microvasculature by X-ray tomography with the unprecedented pixel size of 0.65 μm. Our measurements suggest that the resolving power of the techn…
Parents' role in adolescents' decision on a college major: A weekly diary study
2011
Abstract This study examined 39 adolescents during their transition to university. In standardized weekly diaries over several weeks (M = 8.13) adolescents reported on engagement in career exploration (in-breadth and in-depth self and environmental exploration), their parents' transition-related involvement (frequency of conversations, support, and interference), and their satisfaction with how the transition progressed. The results showed that exploration largely fluctuated across weeks, whereas parent involvement was more stable. Family members' engagement varied according to the phase of the application process the adolescent was involved in. The more adolescents explored during a given …
