Effect of composition information on the perception of innovative beverages mixing animal and plant ingredients by consumers
2021
We studied the reaction of consumers and non-consumers of plant-based alternatives towards beverages mixing cow milk with soy juice or oat juice. We focused on the liking of these products and on the perceived nutritional and environmental quality. We compared the results obtained by presenting the products with or without composition information, with two types of composition information (plant-based or mixed) and between consumers and non-consumers of plant-based alternatives. We found that the plant-based composition information increased the appreciation of products containing oat. Both composition information had a similar impact on the perceived nutritional quality. The mixed composit…
Cropping system dynamics, climate variability, and seed losses among East African smallholder farmers: a retrospective survey.
2014
Abstract Climate variability directly affects traditional low input and rain-fed farming systems, but few studies have paid attention retrospectively to the cropping system’s ability to mitigate climate risk. This study analyzes the impacts of rainfall variability on farmers’ seed variety losses over time, considering changes in smallholder farming systems. The cropping system dynamics, in favoring maize at the expense of sorghum and pearl millet, have induced an increasing risk of seed loss during drought. Combining ecological anthropology and climatology, a retrospective survey asking farmers about the period 1961–2006 was carried out at three altitudinal levels (750, 950, and 1100 m) on …
Biogeography of soil microbial communities: a review and a description of the ongoing french national initiative
2010
International audience; Microbial biogeography is the study of the distribution of microbial diversity on large scales of space and time. This science aims at understanding biodiversity regulation and its link with ecosystem biological functioning, goods and services such as maintenance of productivity, of soil and atmospheric quality, and of soil health. Although the initial concept dates from the early 20th century (Beijerinck (1913) De infusies en de ontdekking der backterien, in: Jaarboek van de Knoniklijke Akademie van Wetenschappen, Muller, Amsterdam), only recently have an increasing number of studies have investigated the biogeographical patterns of soil microbial diversity. A such …
Note preliminari sul rinvenimento di un'area artigianale da Contrada Amone e sulla produzione ceramica nel bacino idrografico del fiume Nocella
2019
Questo articolo esamina le evidenza archeologiche di età romana nella Piana di Partinico, un'area ad Est del Golfo di Castellammare ricca di insediamenti rurali e ville tra cui quella famosa di Sirignano. L'area di contrada Amone, già nota per la presenza di un impianto termale e la scoperta di lacerti di mosaici policromi, si arricchisce adesso di una nuova area artigianale. La scoperta di alcuni scarti di tegole ha fornito l'opportunità per riflettere sulla possibile origine delle tegole bollate ONASOY, di cui si accetta tradizionalmente la provenienza dalla baia di San Cataldo. Viene dunque presentato un esame preliminare degli impasti ceramici provenienti da contrada Amone e baia San Ca…

De l'école unifiée aux écoles plurielles. Évaluation internationale des politiques de différenciation et de diversification de l'offre éducative
2004
The last two decades have been marked in many developed and emerging countries by major educational reforms, around special themes: decentralization, the differentiation of courses and school content and the free choice of school. These three education policies, which aim to differentiate and diversify the educational offer, call into question the traditional organization of modern educational systems. This study seeks to evaluate the effects of these reforms on the performance of education systems, thanks to an econometric analysis based, on the one hand, on the results of the PISA 2000 international evaluation and, on the other, on a a fine description of the institutional characteristics…
A Combined Fuzzy-SEM Evaluation Approach to Identify the Key Drivers of the Academic Library Service Quality in the Digital Technology Era: An Empiri…
2017
A conceptual model of the Academic Library (AL) service quality is hypothesized in the present article, and then validated and analyzed by a novel evaluation approach. Specifically, the conceptual model integrates the fundamental attributes of the canonical AL service together with those more relevant of the new and widely considered AL Electronic Service (e-services). As concerns the evaluation approach, it incorporates the Fuzzy Sets Theory (FST) so as to deal with the students’ uncertainty over their own judgments on the AL service quality and a Structural Equation Model (SEM) to validate the conceptual model and to determine the key drivers of the AL service quality. The effectiveness o…
Explaining the Adoption and Habits of Playing Exergames: The Role of Physical Activity Background and Digital Gaming Frequency
2015
Exergaming, a form of digital gaming that combines physical exercise and video games, has become increasingly common in recent years. Exergaming has also become a subject of growing interest among academic researchers. They can be used to motivate people towards more active and a healthier lifestyle. This study examines the adoption and habits of playing exergames, focusing especially on whether and how exercise and gaming backgrounds are associated with the usage of these types of games. The study is based on analyzing an online survey sample of 1,091 respondents through contingency tables, the Pearson’s χ2 tests of independence, and the Cramér’s V coefficients. The results reveal interest…
Emocionālā intelekta dažādu konstruktu salīdzināšana
2015
Pētījuma mērķis ir savstarpēji salīdzināt Saloveja un Goldmena vispārīgo garastāvokļa iezīmju konstruktu un Šutes emocionālā intelekta konstruktu, un to mērījumu psihometriskos rādītājus. Pētījuma ietvaros tiek noskaidrots, kā saturiski un psihometriski atšķiras Saloveja un Goldmena vispārīgo garastāvokļa iezīmju konstrukts un Šutes emocionālā intelekta konstrukts, neskatoties uz to, ka abas aptaujas izmanto par pamatu vienu un to pašu emocionāla intelekta teoriju. Pētījuma dalībnieki ir studenti no dažādām Latvijas pilsētām – Rīgas (71%), Liepājas (22%), Ventspils (3%), Rēzeknes (3%), Jūrmalas (1%). Respondentu vecums ir no 18 līdz 33 gadiem (M = 22,9). Izlases apjoms ir 70 cilvēku, no tie…
Formare gli studenti universitari alla Cittadinanza Digitale
2023
Today digital media are configured as social environments that expand our personal, cultural, social and educational reality, therefore measuring citizens’ activities in online environments is of fundamental importance. In the last decade, different scholars have proposed different definitions of the digital citizenship and different measurement tools. Most definitions focus on two conceptions of digital citizenship, some more inherent in digital skills and others centered on critical aspects and civic engagement. In this study, we present the translation and Italian adaptation of two scales: the Digital Citizenship Scale by Al-Zahrani (2015) and the Digital Citizenship Scale by Choi, Glass…
