First results of PACTE group's experimental research on translation competence acquisition : the acquisition of declarative knowledge of translation
2014
Autors llistats per ordre alfabètic. Investigadora principal: A. Hurtado Albir This paper presents the first results of empirical-experimental research into the Acquisition of Translation Competence (ATC): the acquisition of declarative knowledge about translation. This study is based on our previous research about Translation Competence (TC). Some of the data collection instruments have, however, been adapted for current use. Details of our research design include type of study, universe and sample population, study variables, data collection instruments, and data analysis processes. The dependent variables were knowledge of translation; translation project; identification and solution of …
Schematic or taxonomic organisation of the reality and the development of class logic
1994
Abstract The experiment studied the effect of various methods of organising reality (taxonomic vs. schematic) on success in inclusion and logical complementation tasks. Seventy-two nine-year-old children were divided into four groups on the basis of their logical structuring abilities. Using three sets of material (Animals, Plants, Means of Transportation), the subjects performed a sorting task and an evaluation task in which the taxonomic and schematic modes of organising reality were opposed. Contrary to our hypothesis, the ″;logical included' did not exhibit a greater capacity for taxonomic organisation than the “empirical includers” of the same age, either in the sorting or the evaluati…
Asset modification for regional industrial restructuring: digitalization of the culture and experience industry and the healthcare sector
2021
This paper researches how firm- and system-level asset modification and alignment underpin and direct new path development from digitalization. It suggests that asset reuse mostly promotes path extension or path upgrading, while asset creation and asset destruction will be more evident in the process of path emergence. The empirics support asset modification as a key mechanism for regional restructuring from digitalization, but suggest that the typology should be more nuanced. Specifically, the empirics demonstrate asset upgrading as a key mechanism. publishedVersion
Personality traits and unemployment: Evidence from longitudinal data
2012
This study contributes to the literature on how personality is related to labour market success by providing evidence on the relationship between personality traits and unemployment. After accounting for reverse causality and measurement error, our results suggest that higher openness was associated with increased cumulative unemployment at the prime working age. It seems that this connection occurs because individuals with higher openness enter into unemployment spells more frequently – not because their unemployment spells would be particularly long. peerReviewed
Why Some Internet Users Don’t Buy Air Tickets Online
2010
This work attempts to identify the determinant variables that make some Internet users not to buy airline tickets online. The Technology Acceptance Model (TAM) and the Theory of Planned Behaviour (TPB) have been used as the conceptual reference framework, with the addition of the influence of perceived risk and trust. The results of the empirical study of Internet users who never have purchased an airline ticket online suggest that both subjective norm and attitude have a direct influence on airline ticket purchase intention. Ease of use has also proved to be a significant variable, because it has an indirect influence on behaviour through perceived usefulness, trust and risk. Risk, trust a…
The Impact of the Direct Participation of Workers on the Rates of Absenteeism in the Spanish Labor Environment.
2020
The aim of this research was to study the relationship between the different levels of direct participation of workers (passive, consultative or active-delegated) in risk prevention management with the levels of absenteeism in Spain. To this end, a transversal study was carried out using microdata from the Second European Survey of Companies on New and Emerging Risks (ESENER-2-Spain, 2014) with a master population of 3162 work centres. A multinomial logistic regression model was carried out, with the dependent variable being the levels of absenteeism and the independent variables, the participation indicators and preventive management, calculating the adjusted odds ratio (aOR) between all t…
A New Method of Velocity Estimation Based on Variable Temporal Basis Using Incremental Encoder
1997
Abstract This paper deals with analysis and synthesis of algorithms for digital conditioning of signals generated by incremental encoders to estimate velocity of rotating devices for control purposes. Main objectives are to obtain high accuracy at low and high velocity and low tracking delays during accelerations. A digital conditioning method is described, Which uses a polynomial of order n whose coefficients are updated so as to fit the n+1 most recent velocity data acquired on a variable temporal basis. Digital sinlulations and experimental findings are shown with the ainl to validate the proposed estimation method and compare it with other methods.
Single-chain variable fragment (scFv) antibodies against rotavirus NSP4 enterotoxin generated by phage display.
2004
The rotavirus non-structural NSP4 protein causes membrane destabilization as well as an increase in intracellular calcium levels in eukaryotic cells and induces diarrhea in young mice, acting as a viral enterotoxin. In this study the phage display technique was used to generate a panel of single-chain variable fragment (scFv) antibodies specific for the NSP4 protein of the human rotavirus strain Wa from a human semi-synthetic scFv library. After several rounds of panning and selection on NSP4 adsorbed to polystyrene tubes, individual scFv were isolated and characterised by fingerprinting and by sequencing the VH and VL genes. The isolated scFv antibodies specifically recognize NSP4 in enzym…
Sequence analysis of the VP7 and VP4 genes identifies a novel VP7 gene allele of porcine rotaviruses, sharing a common evolutionary origin with human…
2005
AbstractDuring an epidemiological survey encompassing several porcine herds in Saragoza, Spain, the VP7 and VP4 of a rotavirus-positive sample, 34461-4, could not be predicted by using multiple sets of G- and P-type-specific primers. Sequence analysis of the VP7 gene revealed a low amino acid (aa) identity with those of well-established G serotypes, ranging between 58.33% and 88.88%, with the highest identity being to human G2 rotaviruses. Analysis of the VP4 gene revealed a P[23] VP4 specificity, as its VP8* aa sequence was 95.9% identical to that of the P14[23],G5 porcine strain A34, while analysis of the VP6 indicated a genogroup I, that is predictive of subgroup I specificity. Analysis …
Rapid evolutionary adaptation to elevated salt concentrations in pathogenic freshwater bacteria Serratia marcescens.
2014
Rapid evolutionary adaptions to new and previously detrimental environmental conditions can increase the risk of invasion by novel pathogens. We tested this hypothesis with a 133-day-long evolutionary experiment studying the evolution of the pathogenic Serratia marcescens bacterium at salinity niche boundary and in fluctuating conditions. We found that S. marcescens evolved at harsh (80 g/L) and extreme (100 g/L) salt conditions had clearly improved salt tolerance than those evolved in the other three treatments (ancestral conditions, nonsaline conditions, and fluctuating salt conditions). Evolutionary theories suggest that fastest evolutionary changes could be observed in intermediate sele…
