Teacher-child interaction quality and children's self-regulation in toddler classrooms in Finland and Portugal
2021
This study examines the association between teacher–child interaction quality and children's self‐regulation in Finnish and Portuguese toddler classrooms. The participants included 230 Finnish (M = 29; SD = 3 months) and 283 Portuguese (M = 30, SD = 4 months) toddlers and their teachers (n = 43 Finland; n = 29 Portugal). The children's behavioural self‐regulation (attention, working memory, and inhibition control) was individually tested, and the teachers evaluated the children's self‐regulation skills in the classroom. The quality of the teacher–child interactions (i.e., emotional and behavioural support and engaged support for learning) was evaluated using the CLASS‐Toddler observation in…
Microgastrinae (Hymenoptera: Braconidae) in the Forest State of Artikutza (Navarra: Spain): Diversity and Community Structure
2013
Microgastrinae is one of the largest subfamilies of the Braconidae with about 2,000 described species worldwide. These wasps are of enormous ecological interest due to their role in controlling the caterpillar populations. This study analyses diversity and community structure within the Microgastrinae in the Artikutza Forest, located in the Peñas de Aia Natural Park, western Pyrenees, Spain. The specimens were collected in two different habitats: mixed forest and beech forest. A total of 524 specimens, belonging to nine separate genera and 27 species were captured. Alpha, beta and gamma diversity were analyzed. Additionally, the relationship between Microgastrinae phenology and climatic con…
A New Phylogenetic Framework for the Animal-Adapted
2018
Tuberculosis (TB) affects humans and other animals and is caused by bacteria from the Mycobacterium tuberculosis complex (MTBC). Previous studies have shown that there are at least nine members of the MTBC infecting animals other than humans; these have also been referred to as ecotypes. However, the ecology and the evolution of these animal-adapted MTBC ecotypes are poorly understood. Here we screened 12,886 publicly available MTBC genomes and newly sequenced 17 animal-adapted MTBC strains, gathering a total of 529 genomes of animal-adapted MTBC strains. Phylogenomic and comparative analyses confirm that the animal-adapted MTBC members are paraphyletic with some members more closely relate…
Essential oil crops for sustainable agriculture - A review
2009
Multifunctionality and diversification of farming systems, integration of agricultural practices both inter se and with the non-agricultural productive systems operating on the territory, biodiversity safeguards, and reduction in off-farm inputs, are key factors for all modern development strategies in agricultural areas. Such issues are valid worldwide, but are especially true in areas in which the cultivation of the more widespread and “classical” crops is constrained by factors of varying degree and importance. In Mediterranean areas, where many environmental and economic factors often reduce rural areas to marginal conditions, the search for new crop opportunities has become one of the …
Wildflowers: opportunities for urban landscapes
2022
The concept of “sustainability” is also becoming of great interest in the management of ornamental and territorial greenery. The new trends in the design of green spaces are aimed both at enhancing their “natural” aspects and at researching schemes characterized by lower maintenance costs. Spontaneous vegetation represents a characteristic component of the urban environment and is always adequate to the conditions of the site in which it is located. In this context, the role of spontaneous herbaceous plants becomes fundamental and constitutes an effective response to the current demand for the defence, conservation and enhancement of biodiversity. So far, the use of spontaneous vegetation f…
Sparsity-aware multiple relay selection in large multi-hop decode-and-forward relay networks
2016
In this paper, we propose and investigate two novel techniques to perform multiple relay selection in large multi-hop decode-and-forward relay networks. The two proposed techniques exploit sparse signal recovery theory to select multiple relays using the orthogonal matching pursuit algorithm and outperform state-of-the-art techniques in terms of outage probability and computation complexity. To reduce the amount of collected channel state information (CSI), we propose a limited-feedback scheme where only a limited number of relays feedback their CSI. Furthermore, a detailed performance-complexity tradeoff investigation is conducted for the different studied techniques and verified by Monte …
Modele eklezjalnej jedności chrześcijan
2018
Dla rozwoju ruchu ekumenicznego potrzeba modeli określających możliwości jednoczenia się chrześcijan. Dialogi ekumeniczne pokazują, że w prawie każdym Kościele chrześcijańskim wyobrażenia o jedności są różne. Z problemem braku jednej wizji jedności łączy się drugi – brak jednego pojęcia Kościoła, a przynajmniej brak takiego jego rozumienia, które byłoby akceptowane przez wszystkich chrześcijan. Trzeci problem związany jest z dwoma poprzednimi i dotyczy ekumenicznej hermeneutyki, która jest uzależniona od różnych eklezjalnych modeli jedności. Wyznaniowe uwarunkowania sprawiają, że inną wizję jedności mają prawosławni, inną protestanci, a jeszcze inną katolicy. Artykuł prezentuje głównie w op…

Frontiera geografica e frontiere mentali nella «Saga di Eirik il Rosso»
2022
La «Saga di Eirik il Rosso» («Eiríks saga rauða») appartiene al gruppo delle “Family Sagas” ("Íslendinga sögur") dell’antica letteratura islandese. Essa si configura come un testo di straordinario interesse storico e antropologico perché contiene una delle più antiche narrazioni della penetrazione dei Vichinghi, prima in Groenlandia e poi nel Nuovo Continente (la cosiddetta Vinlandia), circa 500 anni prima della “scoperta” dell’America da parte di Cristoforo Colombo. Ma è anche un testo ricco di suggestioni che afferiscono alle dimensioni del magico, del meraviglioso, dell’immaginario, e insieme un’opera nella quale la “frontiera” geografica si fonde e si confonde – nella redazione scritta …
The “genetic erosion” of the soil ecosystem
2013
Abstract This paper takes into consideration the influence of human activities on the loss of pedodiversity in a Mediterranean area due to large scale farming. In particular it examines the quantitative and qualitative soil changes in a period of 53 years (from 1955 to 2008) evaluating the loss of soil diversity at soil subgroups level of the USDA Soil Taxonomy system. The following indices were used: richness; Shannon’s diversity index; Simpson diversity index; Shannon’s evenness index; Simpson’s evenness index. In this case study, considering what we observed in time, the human intervention in soil transformation could increase the diversity in the landscape in an initial phase, but forwa…
