BILINGUAL ACQUISITION DATA: CROSS-SECTIONAL CORPUS_SORAUVALAL DATASET

  • Mujcinovic, Sonja
  • Fernández Fuertes, Raquel
This corpus contains oral and written experimental production data from a total of 106 sequential bilingual children for whom English was their L2. These children belong to three groups depending on whether their L1 was Spanish (n=33), Bosnian (n=39) or Danish (n=34). Within each language group, two subgroups appear depending on the time of exposure the children have had to the L2 (either 2 or 4 years). The data were collected in the schools the participants attended in the country where they lived (i.e., Spain, Denmark, and Bosnia). The criteria applied when selecting the participants were the following: - both parents and the child had to share the same L1 (Spanish, Bosnian or Danish depending on the group); - the L2 of the participants had to be English (if the participants had an L3 which they started learning as part of the curricula during the 3rd or the 4th year of instruction of the L2, they were not excluded from the study; otherwise, they were excluded); - the participants had only received instruction in the L2 in educational settings; - the participants had received instruction for either 2 or 4 years at their primary school; - the participants who took part in any exchange programs or lived in an English-speaking country for longer than two weeks were excluded from the study., UVALAL, 1.

BILINGUAL ACQUISITION DATA: SUBJECT OVERTNESS_SO-L2 DATASET

  • Mujcinovic, Sonja
  • Fernández Fuertes, Raquel
This investigation is focused on the contact between [+null subject] and [-null subject] languages. More specifically, it aims at characterizing the nature of crosslinguistic influence from the L1 into the L2 in the specific case of sentential subjects. The target language is L2 English (a [-null subject] language) and three different L1s are considered (i.e., Bosnian and Spanish as [+null subject] languages; and Danish as a [-null subject] language). The study addresses three issues: (i) the role of typology in terms of whether subjects in the L2 share the same parametric option as that in each participant’s L1; (ii) the role of the amount of L2 English exposure in institutional contexts (i.e., 2 and 4 years); and (iii) the role of modality in the data collection process (i.e., oral and written production data). A total of 78 sequential bilingual children with different language pairs have participated: 26 L1 Spanish-L2 English, 26 L1 Bosnian-L2 English and 26 L1 Danish-L2 English. Also 13 L1 English children participated as a control group. Both oral and written production data have been elicited via a free production task and a story telling task, respectively., UVALAL, 1.

CODESWITCHING EXPERIMENTAL DATA: GRAMMATICAL GENDER IN COPULA CONSTRUCTIONS WITH CODESWITCHING

  • Fernández Fuertes, Raquel
  • Gómez Carrero, Tamara
This investigation focuses on the role of Spanish grammatical gender in English-Spanish switched copulative constructions with an adjective as subject complement (e.g., la casa is beautiful / the house es bonita). In particular, the aim of this study is to determine (i) which directionality is preferred and easier to process (i.e., switches in which Spanish provides the subject determiner phrase (DP) and English provides the adjective or structures in which the subject DP is in English while the adjective is in Spanish -e.g., la casa is beautiful vs. the house es bonita-); and (ii) which gender agreement mechanisms are preferred and easier to process in copulative switches in which Spanish provides the adjective. Regarding the latter, two mechanisms are under consideration: the analogical criterion (AC), i.e., whether there is gender agreement between the Spanish adjective and the translation of the equivalent of the English DP subject ([+AC] switches; e.g., the house-SP FEM. es bonita-FEM.) or the lack of the analogical criterion ([-AC] switches; e.g., the house-SP FEM. es bonito-MASC./ the book-SP MASC. es bonita-FEM.); and the masculine as default, i.e., whether masculine adjectives are preferred and easier to process regardless of the gender of the translation equivalent of the English DP (e.g., the book-SP MASC. es bonito-DEFAULT and the house-SP FEM. es bonito-DEFAULT)., UVALAL, (1.)

CODESWITCHING EXPERIMENTAL DATA: GRAMMATICAL PERSON

  • Fernández Fuertes, Raquel
  • Gómez Carrero, Tamara
This investigation focuses on codeswitching happening between the subject and the verb. In particular, it aims at determining how English-Spanish subject-verb switches are perceived and processed by taking into account three issues: (i) the directionality of the switch (i.e., Spanish subject – English verb switches vs. English subject – Spanish verb switches – e.g., el niño-SP DP SUBJ. drinks-EN V / él-SP 3rd PERS. SING. PRON. SUBJ. drinks-EN V vs. the boy-EN DP SUBJ. bebe-SP V/ he-EN 3rd PERS. SING. SUBJ. bebe-SP V); (ii) the categorial nature of the subject (i.e., determiner phrase -DP- vs. pronoun- e.g.,el niño-SP DP SUBJ. drinks-EN V vs. él-SP 3rd PERS. SING. PRON. SUBJ. drinks-EN V ); and (iii) the grammatical person in the case of the pronominal subjects (i.e., first and second person vs. third person pronominal subjects - e.g., I-EN 1st PERS. SING. PRON. SUBJ. quiero-SP V / you-EN 2nd PERS. SING. PRON. SUBJ. juegas-SP V vs. he-EN 3rd PERS. SING. SUBJ. bebe-SP V)., UVALAL, 1. GENERAL INFORMATION : 1.1. Title of dataset ; 1.2.

FULLY BIO-BASED FILMS BASED ON PURIFIED BIOPOLYMER FRACTIONS FROM HYDROTHERMAL EXTRACTION OF DISCARDED CARROTS

  • Ramos Andrés, Marta
  • Hu, Liqiu
  • Grénman, Henrik
  • Xu, Chunlin
  • García Serna, Juan
Flexible 100 % bio-based films were produced from discarded carrots fractions. The main ingredient was purified high molecular weight fractions of hemicelluloses and pectins previously obtained by hydrothermal treatment and ultrafiltration/diafiltration. A fraction of lignin-containing cellulose nanofibers was used as an additive. These nanofibers were obtained from the residual pulp of the hydrothermal treatment after a mechanical treatment. Low content of lignin-cellulose nanofibers (< 5 % w/w) improved oxygen permeability (up to 29 %) but worsened water vapor permeability and tensile properties. A higher addition of lignin-cellulose nanofibers (5-25 % w/w) allowed to recover the properties of the reference film (without fibers) and provided a higher hydrophobicity, increasing the water contact angle from 79.9° to 125.8°. The study of the influence of the molecular weight (67.77-102.75 kDa) and composition of the hemicellulose and pectin fraction in films containing 1 % lignin-cellulose nanofibers showed that a higher molecular weight decreased oxygen permeability (from 48.18 to 41.14 cm3·µm/m2/kPa/day), increased water vapor permeability (from 21.56 to 24.01 g·mm/m2/kPa/day) and decreased hydrophobicity (from 86.84° to 71.10°). Tensile stress was higher with higher pectin content and lower molecular weight (from 1.13 to 2.84 MPa), while elongation was higher with higher hemicellulose content (from 5.92 to 15.28 %). The obtained films had acceptable properties for food packaging and high hydrophobicity, with the great advantage of being 100 % from agri-food waste by applying environmentally friendly processes and without the need for chemical modification., Grupo de Tecnologías a Presión (PressTech), Agencia Estatal de Investigación (Gobierno de España) and FEDER Funds EU [PID2019-105975GB-I00 (MICINN/FEDER, EU)], Junta de Castilla y León - Consejería de Educación and FEDER Funds [CLU-2019-04]

Discarded carrots were valorized to obtain different films. The pulp was subjected to hydrothermal treatment (140 and 180 °C) at pilot scale, with one and with several flow-through reactors in series, allowing the extraction of pectin-containing arabinogalactan (P-AG) of very high molecular weight. Ultrafiltration and diafiltration allowed obtaining purified fractions with molecular weights be-tween 3.48-102.75 kDa. The solid residue from the hydrothermal process was subjected to mechanical treatments to obtain lignin-containing cellulose nanofibers (L-CNFs). The P-AG film had a better oxygen barrier (67.73 vs. 239.83 cm3·µm/m2/kPa/day) and the L-CNFs film had a higher tensile strength (7.74 vs. 3.14 MPa). The combination of both fractions showed that L-CNFs should be added in percentages higher than 15 % (w/w) so that their presence does not harm the P-AG based film. There was a synergistic effect on hydrophobicity when mixing both fractions, reaching a 57.5 % higher water contact angle (125.8 °). As for the P-AG sample, a higher molecular weight decreased the oxygen permeability up to 14.6 % (41.14 cm3·µm/m2/kPa/day) but increased the water vapor permeability up to 11.4 % (24.01 g·mm/m2/kPa/day). The tensile strength was up to 150.9 % higher at lower molecular weight and higher pectin content (2.84 MPa) due to the high degree of branching of the arabinogalactan. Elongation was up to 157.9 % higher at higher arabinogalactan content (15.28 %). For the first time, purified fractions of P-AG and L-CNFs from carrot waste were obtained and used for film formation. The films had acceptable properties for food-packaging., Grupo de Tecnologías a Presión (PressTech), Instituto de Bieconomía de la Universidad de Valladolid, Agencia Estatal de Investigación (Gobierno de España) and FEDER Funds EU [PID2019-105975GB-I00 (MICINN/FEDER, EU)] Junta de Castilla y León - Consejería de Educación and FEDER Funds [CLU-2019-04]
