Social Perceptions and Attitudes Towards Climate Change in Poland and in Turkey
2017
Climate change is perceived as a threat to future human well-being and a challenge to sustainable development of local communities and economies world-wide. While some countries and regions are expected to experience slight gains from the climatic changes the other are exposed to major losses. Ever more frequent natural disasters come as warning symptoms of the changes. However, for the sake of effective and efficient adaptation in various world regions answers to the following questions are important: do people notice this changes, do they experience their negative effects, are they satisfied with the climate change mitigation and adaptation actions taken by the governments, are they willi…
Heterogeneity in general practitioners’ preferences for quality improvement programs: a choice experiment and policy simulation in France
2016
International audience; Despite increasing popularity, quality improvement programs (QIP) have had modest and variable impacts on enhancing the quality of physician practice. We investigate the heterogeneity of physicians’ preferences as a potential explanation of these mixed results in France, where the national voluntary QIP – the CAPI – has been cancelled due to its unpopularity. We rely on a discrete choice experiment to elicit heterogeneity in physicians’ preferences for the financial and non-financial components of QIP. Using mixed and latent class logit models, results show that the two models should be used in concert to shed light on different aspects of the heterogeneity in prefer…
Meat quality of commercial chickens reared in different production systems: industrial, range and organic
2020
Abstract Meat is an important part of the human diet since it provides several nutrients. However, the amount of these nutrients can differ according to several factors. With this in mind, the present research was designed with the main objective of evaluating the effect of production system of broiler chickens (industrial, range and organic) on meat quality. The physicochemical, chemical and nutritional characteristics were determined in breast and drumstick meat. The organic chickens presented the lowest amounts of fat and cholesterol and the highest amounts of protein. The colour was also influenced by the production system, where organic and range chickens had the highest values of redn…

Neoclassical Convergence Versus Technological Catch-Up : A Contribution for Reaching a Consensus.
2004
http://www.businessperspectives.org/files/ppm/PPM_EN_2004_03pp15_42.pdf; International audience; New macro empirical evidence is provided to assess the relative importance of object andidea gaps in explaining the world income distribution dynamics over a benchmark period of 1960-1985. Results are then extended through 1995. Formal statistical hypothesis tests allow us to discriminatebetween two competing growth models: (i) the standard neoclassical growth model similarto that employed by Mankiw, Romer, and Weil (1992), and (ii) an endogenous growth modelclosely related to the Nelson and Phelps' approach (1966) that emphasizes the importance of technologytransfer in addition to factor accumu…
Rice cooking and sensory quality
2019
International audience; This chapter provides a state-of-the-art review of the diversity and dynamics of consumer demand with respect to the eating quality of rice worldwide. Quality includes both tangible measurable factors (rice characteristics) and the context of consumption. The main sensory attributes evaluated around the world are described, and their relationship with the diversity of consumer demand is discussed. Instrumental methods for predicting quality measured on either raw or cooked grains are reviewed. The changes that occur in the rice grain during cooking are described along with a modeling approach able to predict the changes and their spatial distribution in the rice grai…
The role of passenger modal shift nodes in the interaction between land use and transport system
2011
In the last years we have observed a sub-urbanization process or 'sprawl' process (low density inhabitant models), caused by new economic and production conditions, by a free diffusion of new habitant models in territory, by new organization models of social relationships and by one-side power of road mode and in particular the private use. Commuters need to reach quickly own destinations and the traffic and parking problems in central areas increase mainly the importance of multi-modal displacements in an integrated transport system between public and private mode. Planner role should re-balance modal choice in favour to public transport and motivate passenger intermodality integrating the…
Past and present “Urban voids” as resources for the future. The case-study of Catania
2002
Since the end of the 1960s, the landscapes of major cities have been more and more characterized by the presence of "urban voids". Today these "voids", which are often heterogeneous in their manifestation, dominate the discussions about the transformation and the future of urban areas. The reclaiming and re-use of derelict sites and "cultural heritage" has the duty to assure for the next generation the knowledge of the cultural values of the past. In this paper we will focus our attention on a re-used "cultural heritage": the Multifunctional Centre of Catania (Sicily, Objective 1 region). Thanks to the Urban Programme this "urban void"- abandoned for decades and deteriorated - was recovered…
Geographies of markets: Materials, morals and monsters in motion
2010
Approaching processes of capitalist market exchange from a cultural economic perspective, we identify three strands of research that are all part of a widespread ‘pragmatic turn’ in the study of economic activities: (1) the conceptualization of markets as heterogeneous arrangements of people, things and sociotechnical devices; (2) the insight that multiple frames of reference are mobilized in everyday market activities in addition to instrumental rationality; and (3) approaches that combine an interest in the performance of diversity and difference in concrete market contexts with an attention to mobility in network capitalism.
Factors Influencing Point Measurement of Near-surface Saturated Soil Hydraulic Conductivity in a Small Sicilian Basin
2017
Hydraulic conductivity of saturated soil, Ks, controls many hydrological processes. Parameterization of basin hydrological models in terms of Ks is complicated and uncertain owing to the very high spatial variability of this soil property. A small Sicilian basin was intensively sampled by the simplified falling head technique to obtain spatially distributed Ks data, and an attempt to explain their spatial variability on the basis of soil physical characteristics, digital elevation model-derived topographic attributes and land cover was carried out. High Ks values were obtained when clay content was low and both elevation and mean slope were high. Moreover, differences in Ks among land cover…
