Assessing the Effect of Drivers’ Gender on Their Intention to Use Fully Automated Vehicles
2021
Although fully automated vehicles (SAE level 5) are expected to acquire a major relevance for transportation dynamics by the next few years, the number of studies addressing their perceived benefits from the perspective of human factors remains substantially limited. This study aimed, firstly, to assess the relationships among drivers’ demographic factors, their assessment of five key features of automated vehicles (i.e., increased connectivity, reduced driving demands, fuel and trip-related efficiency, and safety improvements), and their intention to use them, and secondly, to test the predictive role of the feature’ valuations over usage intention, focusing on gender as a key …
FOTOHROMĀ EFEKTA IZCELSME AR DZELZI AKTIVĒTĀ BĀRIJA MAGNIJA SILIKĀTĀ
2022
BaMgSiO4:Fe ir viens no visizteiksmīgākajiem neorganiskajiem fotohromiem materiāliem, tomēr fotohromā efekta izcelsme BaMgSiO4:Fe nav viennozīmīgi izskaidrota. Darbā ir sintezēti BaMgSiO4:Fe paraugi, un tie ir pētīti ar difūzās atstarošanās optiskās spektroskopijas un elektronu paramagnētiskās rezonanses (EPR) spektroskopijas metodēm. Darbā apspriesta fotohromā efekta izcelsme BaMgSiO4:Fe, kā arī noteikta optimālā Fe koncentrācija un sintēzes apstākļi efekta pastiprināšanai.
Multifunctionality: Epistemic diversity and concept oriented research clusters
2008
International audience; This paper provides a mapping of the different uses of the word multifunctionality. To explore the diversity of meanings and interpretations, a comparative analysis was conducted through five national case studies in France, the Netherlands, Poland, Spain and Switzerland. The analysis conducted at national level makes it possible to identify eight Concept Oriented Research Clusters (CORCs), based on a relative homogeneity in the research practices, in the research questions addressed, in the concepts used or discussed by scientists to lead their work and in the scientific disciplines, the stream of thought or possibly the epistemic community researchers belong to. Th…
Multifunctionality: refocusing a spreading, loose and fashionable concept for looking at sustainability?
2008
International audience; The notion of agriculture's Multifunctionality (MF) emerged in the 1980s. It then followed two trajectories since the 1990s: a conflicting period linked to its use in the international trade negotiations on the one hand, a spreading in terms of meaning, use and geographically on the other hand. Specific meanings appeared in connection with policy making, at national or international levels, or through the involvement of new disciplines. Yet, very few authors discuss the implication of the chosen meaning on their findings. To explore and take advantage of using this word and to deliver it from its controversial use in international trade negotiations, it is absolutely…
