Surface soil humidity retrieval by means of a semi-empirical coupled SAR model
2010
In the last years, the availability of new technologies of Earth Observation encouraged researches to use integrated approaches for environmental monitoring. Even for agro-hydrological applications, remotely sensed data are available on wide areas allowing the retrieval of cost-effective and representative estimation of high spatial and temporal variability of the soil-vegetation system variables. In particular, soil water content plays an important role determining the partition of precipitation between surface runoff and infiltration and, moreover, influences the distribution of the incoming radiation between latent and sensible heat flux. As a consequence, distributed soil water content …
Rural Society, Social Inclusion and Landscape Change in Central and Eastern Europe:A Case Study of Latvia
2009
The countryside of Europe is undergoing many social, economic and environmental changes as a result of depopulation and agricultural land abandonment. This trend, driven in part by the wide disparity of income levels between rural and urban inhabitants, is particularly evident in the Central and Eastern European countries such as Latvia, which joined the EU in 2004 and in 2007. Research was undertaken in Latvia in 2003, the year before it joined the EU, to explore this trend, as manifested in the relationship of people to the countryside, using focus groups and a questionnaire survey. The results showed that, although Latvians retain a strong regard for their traditional countryside landsca…
Assessment of site-specific drivers of farmland abandonment in mosaic-type landscapes: A case study in Vidzeme, Latvia
2018
Abstract Farmland abandonment, which causes changes in rural life and farming practices, can be observed throughout Europe. Over the last decades natural afforestation has decreased the area of farmland used for agricultural production, thereby leading to landscape homogenization and polarization. This process is explicitly evident in mosaic type landscapes consisting of highly complex land cover patterns, soil composition and topography. The aim of the study was to determine the site-specific driving forces of farmland abandonment at landscape scale in relation to agro-ecological and geographic factors, in a post-Soviet country in Eastern Europe. An extensive field survey approach with sta…
Dispersal of larval and juvenile seabream: Implications for Mediterranean marine protected areas
2015
International audience; In the marine context, information about dispersal is essential for the design of networks of marine protected areas (MPAs). Generally, most of the dispersal of demersal fishes is thought to be driven by the transport of eggs and larvae in currents, with the potential contribution of dispersal in later life stages relatively minimal.Using otolith chemistry analyses, we estimate dispersal patterns across a spatial scale of approximately 180 km at both propagule (i.e. eggs and larvae) and juvenile (i.e. between settlement and recruitment) stages of a Mediterranean coastal fishery species, the two-banded seabream Diplodus vulgaris. We detected three major natal sources …
The refugee entrepreneurship process from/in emerging economies
2021
The paper examines several refugee experiences in Mexico and presents their reasons for leaving their home countries. A gap in research is identifying the entrepreneurial process experienced by refugee entrepreneurs. We use the case study of 10 Latin American refugees in Mexico to propose a conceptual framework that describes the entrepreneurial process of refugee entrepreneurs. We have found that this process begins with the abandonment of the country of origin, followed by the traumatic experiences that caused flight and the difficulties they face in the pilgrimage to the host country. These events help shape the entrepreneurial intention of the refugees.
Choices and Enrollments in French Secondary and Higher Education: Repercussions for Second-Generation Immigrants
2013
En ligne sur http://www.jstor.org/discover/10.1086/670729?uid=16804784&uid=3738016&uid=2129&uid=2134&uid=2&uid=70&uid=3&uid=67&uid=16735408&uid=62&uid=5909928&sid=21102655856551; International audience; In France, the proportion of second-generation immigrants enrolling in tertiary education has increased as education has undergone a process of "democratization." This article analyzes their postsecondary choices, access to tertiary programs, dropout, and transition to the labor market, compared to those of students of French origin. Youths of Portuguese origin are more likely to enter vocational higher programs concordant with their preferences and have better chances of completing a tertia…
Quantitative Characteristics of Information Society and ICT Industry in Latvia
2015
Abstract The article is devoted to statistical analysis of information and communication technology (ICT) industry in Latvia and the development of Information Society in the country. On the basis of statistical data comparison of Latvia with other European countries is made. This comparison shows that Latvia belongs to countries with very well developed Internet. On the other hand the statistical data points on the fact that it is necessary to increase the awareness of population regarding possibilities offered by using of ICT and e-Government.
Consequences of the Abandonment of Mandatory Joint Audit : An Empirical Study of Audit Costs and Audit Quality Effects
2016
Abstract This paper focuses on the unique Danish setting in examining the consequences of abandoning a mandatory joint audit regime. We study the effects on audit costs (measured by audit fees) and audit quality (measured by abnormal accruals) of the abandonment of the mandatory joint audit in Denmark in 2005. We perform our analysis on non-financial listed Danish companies for the 2002–2010 period. Our results show that a joint audit is associated with higher fees, but that the association between joint audit and abnormal accruals is insignificant. This suggests that the higher audit fees cannot be explained by higher audit quality. Our results are robust to alternative measurements of fee…
Does strategy matter? A comparison of broadband rollout policies in Finland and Sweden
2008
This study investigates broadband policies applied in Finland and Sweden with special reference to the geographical coverage of the required network infrastructure. These two Nordic countries are seen as forerunners in the development of the information society, and they also share several other similarities bearing relevance to the take-up of broadband. However, they have applied different broadband strategies: Sweden, one of the first-movers in this field, already launched its ambitious and interventionist national ICT infrastructure program in 2000, whereas the Finnish broadband strategy, published in 2003, largely relies on market forces. The present article analyses these broadband str…
INFLUENCE OF THE CHEMICAL POTENTIAL ON THE CARRIER EFFECTIVE MASS IN THE THERMOELECTRIC SOLID SOLUTION Cu2Zn1-xFexGeSe4
2013
In this paper, we describe the synthesis and characterization of the solid solution Cu 2 Zn 1-x Fe x GeSe 4. Electronic transport data have been analyzed using a single parabolic band model and have been compared to Cu 2+x Zn 1-x GeSe 4. The effective mass of these undoped, intrinsically hole conducting materials increases linearly with increasing carrier concentration, showing a non-parabolic transport behavior within the valence band.
