Tuning of the Thermoelectric Figure of Merit of CHNHMI (M=Pb,Sn) Photovoltaic Perovskites
The hybrid halide perovskites, the very performant compounds in photovoltaic
applications, possess large Seebeck coefficient and low thermal conductivity
making them potentially interesting high figure of merit () materials. For
this purpose one needs to tune the electrical conductivity of these
semiconductors to higher values. We have studied the CHNHMI
(M=Pb,Sn) samples in pristine form showing very low values for both
materials; however, photoinduced doping (in M=Pb) and chemical doping (in M=Sn)
indicate that, by further doping optimization, can be enhanced toward
unity and reach the performance level of the presently most efficient
thermoelectric materials.Comment: 9 pages, 2 figures + toc figur
Psychosocial Outcomes in Long-Term Cochlear Implant Users
OBJECTIVES:
The objectives of this study were to investigate psychosocial outcomes in a sample of prelingually deaf, early-implanted children, adolescents, and young adults who are long-term cochlear implant (CI) users and to examine the extent to which language and executive functioning predict psychosocial outcomes.
DESIGN:
Psychosocial outcomes were measured using two well-validated, parent-completed checklists: the Behavior Assessment System for Children and the Conduct Hyperactive Attention Problem Oppositional Symptom. Neurocognitive skills were measured using gold standard, performance-based assessments of language and executive functioning.
RESULTS:
CI users were at greater risk for clinically significant deficits in areas related to attention, oppositional behavior, hyperactivity-impulsivity, and social-adaptive skills compared with their normal-hearing peers, although the majority of CI users scored within average ranges relative to Behavior Assessment System for Children norms. Regression analyses revealed that language, visual-spatial working memory, and inhibition-concentration skills predicted psychosocial outcomes.
CONCLUSIONS:
Findings suggest that underlying delays and deficits in language and executive functioning may place some CI users at a risk for difficulties in psychosocial adjustment
The internationalization of Italian firms in India: some empirical evidences
This study explores the characteristics of Italian foreign direct investment (FDI) in India and aims at filling the gap identified in the literature by providing a comprehensive empirical analysis on this issue. More specifically, we try to understand the reasons behind internationalization decisions in India, the strategic goals associated with them (i.e. manufacturing vs. commercial), the role played by the Indian subsidiary and its value chain configuration. In order to investigate the research questions, a unique database of Italian firms that invested in India was created. The first empirical confirmation we collected was about the low number of Italian companies with subsidiaries in India. In terms of internationalization goals it emerges clearly from the research that the main target is market seeking. In order to acquire that market share Italian companies have organized their subsidiaries as partially independent companies, adopting a typical “Multidomestic” approach customizing products and services to the local needs and demands.Moreover, the industry fragmentation suggests that so far only the best in each class hav approached India. This is indirectly confirmed by the fact that it is indeed almost impossible to find two Italian competitors present at the same in India.India, internationalization, FDI, value chain
Subsidiary’s Embeddedness of Italian SMEs in Central and Eastern European Countries (CEECs)
This paper is focused on relationships which involves the subsidiary both, at an internal (mainly with the headquarter) and at an external level (with economic actors at a local level, i.e. customers and suppliers). In so doing, corporate and external embeddedness (Andersson and Forsgren, 1996) are investigated under a network based approach. To reach this aim, the level of autonomy and control perceived by the subsidiary and the range of value chain activities managed at local level are used as proxy of the degree of corporate embeddedness. At the same time, the number, frequency, and type of relations activated with local supplier and customers and the number and types of cooperation agreements with local enterprises are used to investigate external embeddedness. The attention is focused on Italian SMEs internationalized in the Central and Eastern European Countries (CEECs). With this respect, the sample is composed by firms that widely differ in terms of location, size, year of subsidiary establishment, and industry. The main evidence resulting from the analysis is that in the CEECs – and particularly in the more developed countries within the Region (such as Poland) – is emerging a phenomenon we define “re-localization”. By this term we describe a rising number of firms that is progressively transferring in these countries a wider range of activities, including the more value added ones. The delocalization of less value added activities (typically high-labour intensive and not complex manufacturing) was generally considered the main strategic aim for companies in the CEECs. Our data, on the contrary, seems to demonstrate that such a delocalization do not represent the ultimate result of the internationalization process, but only a step of a wider process. A process aimed at transferring abroad the whole value chain activities in order to serve the local market. Therefore, the internationalization of most of the analysed firms is market-oriented, i.e. aimed at looking for a new market, able to replace the Italian one
