Photoluminescence properties of S2 molecule trapped in Melanophlogite
2015
We studied the photoluminescence properties of a sample of SiO2-clathrate Melanophlogite, a crystalline microporous material which is found in nature as a rare mineral. Upon β irradiation, the material displays an intense light emission under near-UV illumination. We studied in detail this optical activity by steady-state and time-resolved photoluminescence measurements as a function of temperature. The spectroscopic properties we find can be ascribed to a population of quasi-free molecules trapped within each of the two different types of cage available in the structure of this clathrate, although the spectroscopic properties of the guest molecules are affected by their interactions with t…
Stable carbon and oxygen isotope fractionation in bivalve (Placopecten magellanicus) larval aragonite
2008
Abstract The relationship between stable isotope composition (δ13C and δ18O) in seawater and in larval shell aragonite of the sea scallop, Placopecten magellanicus, was investigated in a controlled experiment to determine whether isotopes in larval shell aragonite can be used as a reliable proxy for environmental conditions. The linear relationship between δ13CDIC and δ13Caragonite (r2 = 0.97, p δ 13 C DIC = 1.15 ( ± 0.05 ) ∗ δ 13 C aragonite - 0.85 ( ± 0.04 ) The relationship between δ13CDIC and δ13Caragonite described for P. magellanicus resulted in larval shell aragonite that was depleted on average by 1.82‰ (SD = 0.22‰, range = 1.1–2.1‰) from predicted equilibrium values based on the r…

Postharvest quality and sensory attributes of organically grown Ficus carica L.
2021
This study evaluates some physical and chemical characteristics and sensory descriptors of fig fruit cultivars ‘Petrelli’ and ‘Fico di Terlizzi’, belonging to the national germplasm bank of fig trees and cultivated in Southern Italy. For the sensory evaluation of external appearance, the descriptors skin color, pulp color, odor, sweetness, stickiness, bitterness, juiciness, firmness, tannic taste and presence of achenes were measured. Results showed that fresh weight, total soluble solids (TSS), titratable acidity (TA), TSS:TA, firmness, and sensory properties were different for the two cultivars. SSC was more correlated with sensory attributes than TA, but other factors were also important…
Italica (Seville, Spain): use of local marble in Augustan age
2010
This study concerns 51 marble finds made of “Cipollino verde” coming from the ancient city of Italica (north of the modern city of Santiponce, 9 km NW of Seville, Spain), the earliest Roman settlement in Spain, founded in 206 B.C. The aim of this work was to determine their provenance from Greek and Italian quarries or from local quarries worked in the Iberian Peninsula. Thin-section optical microscopy, X-ray powder diffraction, bulk rock chemistry and O, C and Sr stable isotope analyses were carried out. Results were compared with literature data on “Cipollino verde” marbles quarried in southern Euboea (Greece), Apuan Alps (Italy), Almería, Extremoz, Seville (Spain) and Évora (Portugal). T…
Autobiographical texts written by learners of Catalan as an Additional Language: From formative needs to reflection in the teaching of narrative genr…
2022
In this article we analyse autobiographical narrative texts written by university students studying Catalan as an Additional Language at a CEFR (2020) B1 level. The goal is to analyse the formative needs related to the writing of this genre in order to foster metadiscursive reflection in the classroom that will allow students to improve their written output. To this end, we analyzed a corpus of 39 autobiographies at both the macrotextual level (i.e., rhetorical moves) and the microtextual level (i.e., deictic elements which channel the narrative’s organization). Our results show that the problems that these texts present for students are related to awareness of the elements that define the …
Latvijas kredītiestāžu klientu izpētes veikšanas problemātika starptautisko un nacionālo prasību ievērošanas kontekstā
2021
Starptautisko ekspertu (MONEYVAL) 2018. gada neapmierinošs vērtējums par Latvijas valsts spējām nepieļaut savas finanšu sistēmas izmantošanu noziedzīgi iegūtu līdzekļu legalizēšanai, kā arī potenciālie draudi tikt iekļautai “pelēkajā sarakstā”, rezultējās valdības lēmumā par finanšu sektora “kapitālo remontu”. Veiktās izmaiņas, t.sk. normatīvajā regulējumā, tika atzinīgi novērtētas no starptautisko ekspertu puses, tomēr šobrīd, pētot notikušo pārmaiņu samērīgumu un ietekmi tiesību zinātnieki, finansisti un ekonomisti nonāk pie secinājumiem, ka veicot “kapitālo remontu” esam pārcentušies. Praksē tas izpaužas virknē problēmu, piemērām, pārspīlēti detalizētā regulējumā, kas pēc būtības ietekmē…

2022
本研究の目的は，大学教員養成におけるグローバル教員研修が，大学院生（現 職教員・大学生）の「教員 21 世紀型スキル」に関する自己効力感にどのような変容を もたらすかを明らかにすることである。研修は，１ . 対話型ボトムアップ研修，２ ．フィン ランドの教育改革研修，及び，３ ．教科連携の CLIL・STEAM に拠る授業訪問を特徴 とする。次世代の児童・生徒が，学びを実社会へ転移するような教育を実現する教員の 21 世紀型スキルとは何か，国際間比較をとおした俯瞰的な研修を目指す。研究方法は， 『Edu 21st：教員 21 世紀型スキルの自己効力感尺度』の 47 質問項目をもちいた事前 と事後の変容，およびポートフォリオ記述分析である。その結果，Edu21st（３ 因子構 造）で差が認められ，「分析的デザイン思考能力」で最も変化が大きいことが明らかにな り，異分野連携の協働中に起こる異質な考えに対する葛藤への価値付けが見られた。 peerReviewed
