Competences of Flexible Professionals: Validation of an Invariant Instrument across Mexico, Chile, Uruguay, and Spain
[EN] The purpose of this study was to validate and test latent mean differences in a second-order factorial structure for self-assessed competences across four Spanish-speaking countries (Spain, Chile, Mexico, and Uruguay). Assessments of 11,802 higher education graduates about their own level of competences were examined. According to our findings, latent mean differences observed in our data lend support to earlier findings in the context of universities from these four countries. In order to compare assessments from different countries, we previously found support for metric and scalar invariance in a second-order factor structure, including innovation, cooperation, knowledge management, and communication, organizational and participative competences. These findings have serious managerial implications in regard to institutional evaluations developed by national accreditation bodies and identification of competence requirements by the labor market. In addition, our research provides a powerful tool for young students and employers, as it contains valuable information about what competences should be expected by students when finishing their studies.This research was funded by the European Commission, grant number AML/19.0902/04/16909/II-0546-A, and grant number CIT2-CT-2004-506352.Conchado Peiró, A.; Carot Sierra, JM.; Vázquez Barrachina, E.

Strong and weak points in competence - based training according to Spanish Higher Education graduates
[EN] The objective of this study is to analyze from a descriptive point of view the competences considered by
higher Education graduates as strengths or weaknesses in their studies. This objective arises from the
growing importance that competences have acquired during the preceding years due to the adaptation
process of university degrees to the European Higher Education Area. With this aim in mind some
specific results, based on a sample of 5,474 Spanish university graduates and thirteen study programs,
are described. Data were obtained from the research project REFLEX «The Flexible Professional in the
Knowledge Society: New Demands on Higher Education in Europe». Universities from fourteen
European countries and Japan participated in the project, and one of the aims was the analysis of
competencies in Higher Education. Results describe how graduates point out to competences related
to traditional teaching methods as strengths of their studies, such as knowledge of the field of study,
ability to analyze and learn and teamwork, whereas competences related to information and
communication technology, and also leadership and ability to speak foreign languages, are revealed as
weaknesses of university studies. Besides, several peculiarities have been identified according to the
following fields of study: Humanities, Sciences, Engineering, Architecture and Economy and finally Fine
Arts.[ES] El objetivo del trabajo es el análisis exploratorio descriptivo de las competencias que los titulados
universitarios consideran puntos fuertes o débiles en sus estudios. Este objetivo se plantea a raíz de la
creciente importancia que las competencias han cobrado en los últimos años debido al proceso de
adaptación de las titulaciones universitarias al Espacio Europeo de Educación Superior. Para ello se
describen los resultados obtenidos en base a una muestra de 5.474 graduados universitarios españoles y
trece titulaciones universitarias. Dichos datos proceden del proyecto de investigación REFLEX «El
Profesional Flexible en la Sociedad del Conocimiento: Nuevas exigencias en la Educación Superior en
Europa» en el que participaron universidades de catorce países europeos y Japón, entre cuyos objetivos
se encontraba el estudio de las competencias en el ámbito universitario. Los resultados muestran que
los graduados universitarios señalan como puntos fuertes de sus estudios las competencias relacionadas
con las metodologías docentes tradicionales como los conocimientos, la capacidad de análisis y
aprendizaje o el trabajo en equipo. Por el contrario, las competencias relacionadas con la gestión de las
tecnologías de la información y las comunicaciones así como las habilidades de liderazgo y comunicación
en idiomas extranjeros se revelan como puntos débiles de los estudios universitarios. Asimismo se han
identificado determinadas particularidades de la formación en competencias en función de las
siguientes áreas de estudio: Humanidades, Ciencias, Ingeniería, Arquitectura y Economía y finalmente
Bellas Artes.Conchado Peiró, A.; Carot Sierra, JM. (2013). Puntos fuertes y débiles en la formación por competencias según los graduados universitarios españoles. REDU. Revista de Docencia Universitaria. 11(1):429-446. https://doi.org/10.4995/redu.2013.5608S42944611
Proposal of a composite indicator for measuring social media presence in the wine market
[EN] Cybermetrics field is attracting considerable interest due to its utility as a
data-oriented technique for research, though it may provide misleading
information when used in complex systems. This paper outlines a new
approach to market research analysis through the definition of composite
indicators for cybermetrics, applied to the Spanish wine market. Our findings
show that the majority of cellars were present in only one or two social media
networks: Facebook, Twitter or both. Besides, the presence on the Web can be
summarized into three principal components: website quality, presence on
Facebook, and presence on Twitter. Three groups of cellars were identified
according to their position in these components: cellars with a high number of
errors in their website with complete absence of information in social media,
cellars with strong presence in social media, and cellars in an intermediate
position. Our results constitute an excellent initial step towards the definition
of a methodology for building composite indicators in cybermetrics. From a
practical approach, these indicators may encourage cellar managers to make
better decisions towards their transition to the digital market.This work was carried out within the framework of a Spanish research project ‘eMarketwine:
diseño de un método y una herramienta de online information intelligence orientada a la
recomendación geolocalizada para el mercado del vino’ (Ref. CSO2016-78775-R), founded
by the Ministerio de Economía y Competitivad (Spanish Ministry of Economy and
Competitiveness).Conchado Peiró, A.; Carot Sierra, JM.; Vázquez Barrachina, E.; Orduña Malea, E. (2020). Proposal of a composite indicator for measuring social media presence in the wine market.

Computer learner corpora: analysing interlanguage errors in synchronous and asynchronous communication
[EN] This study focuses on the computer-aided analysis of interlanguage errors made by the
participants in the telematic simulation IDEELS (Intercultural Dynamics in European
Education through on-Line Simulation). The synchronous and asynchronous
communication analysed was part of the MiLC Corpus, a multilingual learner corpus of
texts written by language learners from different language backgrounds. The main
research questions centred on the differences in the amount and types of errors found in
both the synchronous and asynchronous modes of communication, and whether different
L1 groups committed certain errors more than their counterparts from other mother tongue
backgrounds. As we hypothesised, more errors were found in the synchronous mode of
communication than in the asynchronous; however, when examining the exact types of
errors, some categories were more frequent in the synchronous mode (the formal and
grammatical errors, among others), while in the asynchronous, errors of style and lexis
occurred more frequently. A analysis of the data revealed that the frequency of error types
varied with each different L1 group participating in the simulation, this same analysis also
showed that highly relevant associations could be established the participants’ L1 and
specific error types.Penny MacDonald would like to acknowledge the research grant awarded by the Research and Development Support Programme (PAID-00-10) of the Universidad Politécnica de Valencia in 2010Mac Donald, P.; García Carbonell, A.; Carot Sierra, JM.

Are Water User Associations Prepared for a Second-Generation Modernization? The Case of the Valencian Community (Spain)
[EN] This work focuses on the situation of the technological transition to new technologies in drip irrigation in the Valencian Community (Spain). The study covers the last decade with data from interviews to managers of Irrigation Communities in 2010 and 2018. We analyze the main technological problems in seven topics: (i) Catchment & Pumping; (ii) Storage & Regulation; (iii) Treatment & Filtering; (iv) Transport & Distribution; (v) Maneuver, Regulation & Protection; (vi) Automation; (vii) Theft and Vandalism. We also have researched the influence of the performance of the Automation system, the presence of a technician in the Irrigation Community and the use of sensors or climatic data. Results show that problems related to technological maintenance of filtering systems or automation are very common and important and they are more important in large Irrigation Communities. We have also observed that mostly large ICs are using sensors or climatic data for their irrigation schedule. We can conclude that their current situation is focused in the daily maintenance of technological problems, inherited from the first modernization processes at the beginning of 21st century. Hence, they are far away from a second stage of modernization or the smart irrigation pushed by the new advances on technology.González-Pavón, C.; Arviza Valverde, J.; Balbastre Peralta, I.; Carot Sierra, JM.; Palau-Salvador, G.

[ENG] On these last years an intense research work has been developed in the field of
“competencies based education”. This interest come from the need for European universities
to adapt to the new European Space for Higher Education but also from the compromise for
Higher Education Institutions to improve the quality of its services, this is “education”. Up to
now there is not a thorough consensus about the meaning of “competencies”. Only and as a
product of the progressive implementation of Bologna process has been a bigger stress on the
concept of “learning outcomes”. Such concept is directly related to the former but there are
some aspects related to different agents involved in both processes that make some
difference. At the beginning the concept of “competency” was restricted to the set of manual
or instrumental capabilities needed to the correct performance of the tasks required in the job
position. Or either to the capability to accumulate knowledge related to a certain subject.
Fortunately during these last years new ideas have been introduced that allow to surpass the
simple consideration of manual or practical skills adding new dimensions to the conpt of
“competency”. The Project is based on a survey on university graduates that engaged on work five years
previous to the moment of the study
Assessment of vine-shoots in a model wines as enological additives
[EN] For the first time, the possibility of using vine-shoots as enological additives, similar to oak chips, is proposed. Their volatile and phenolic compounds contribution to a model wine was studied. Variables such as vine-shoot vinifera (Airen and Cencibel), size (chip and granule), toasting (toasted and non-toasted), dosage (4 and 12 g/L) and maceration time (1, 7, 21, 35 and 120 days) were tested. Results showed an important transference of high-value enological compounds after 35 days of maceration with 12 g/L of toasted vine-shoots. Vanillin or guaiacol were found in concentrations always higher than their wine odor thresholds, depending on the variety and vine-shoot formats used. Moreover, trans-resveratrol and ellagic acid stand out for their high concentrations. This transference rate shows the enological aptitude of vine-shoots with a possibly positive contribution in real wines, both at sensory and functional level, although future studies in real wines must be carried out.Many thanks for the financial support given by the Ministry of Economy and Competitiveness-FEDER of the Spanish Government to the Project AGL2015-65133-C2-1-R.

A practical solution to estimate the sample size required for clinical prediction models generated from observational research on data
[EN] Background Estimating the required sample size is crucial when developing and validating clinical prediction models. However, there is no consensus about how to determine the sample size in such a setting. Here, the goal was to compare available methods to define a practical solution to sample size estimation for clinical predictive models, as applied to Horizon 2020 PRIMAGE as a case study. Methods Three different methods (Riley's; "rule of thumb" with 10 and 5 events per predictor) were employed to calculate the sample size required to develop predictive models to analyse the variation in sample size as a function of different parameters. Subsequently, the sample size for model validation was also estimated. Results To develop reliable predictive models, 1397 neuroblastoma patients are required, 1060 high-risk neuroblastoma patients and 1345 diffuse intrinsic pontine glioma (DIPG) patients. This sample size can be lowered by reducing the number of variables included in the model, by including direct measures of the outcome to be predicted and/or by increasing the follow-up period. For model validation, the estimated sample size resulted to be 326 patients for neuroblastoma, 246 for high-risk neuroblastoma, and 592 for DIPG. Conclusions Given the variability of the different sample sizes obtained, we recommend using methods based on epidemiological data and the nature of the results, as the results are tailored to the specific clinical problem. In addition, sample size can be reduced by lowering the number of parameter predictors, by including direct measures of the outcome of interest.This work is funded by the HORIZON2020 PRIMAGE project (RIA, topic SC1DTH 07-2018), from the EU Framework Programme for Research and Innovation of the European Commission.Baeza-Delgado, C.; Cerdá Alberich, L.; Carot Sierra, JM.; Veiga-Canuto, D.; Martinez De Las Heras, B.; Raza, B.; Marti-Bonmati, L.

Glioblastoma versus solitary brain metastasis: MRI differentiation using the edema perfusion gradient
[EN] Background and Purpose:
Differentiation between glioblastoma multiforme (GBM) and solitary brain metastasis (SBM) remains a challenge in neuroradiology with up to 40% of the cases to be incorrectly classified using only conventional MRI. The inclusion of perfusion MRI parameters provides characteristic features that could support the distinction of these pathological entities. On these grounds, we aim to use a perfusion gradient in the peritumoral edema.
Methods:
Twenty-four patients with GBM or an SBM underwent conventional and perfusion MR imaging sequences before tumors' surgical resection. After postprocessing of the images, quantification of dynamic susceptibility contrast (DSC) perfusion parameters was made. Three concentric areas around the tumor were defined in each case. The monocompartimental and pharmacokinetics parameters of perfusion MRI were analyzed in both series.
Results:
DSC perfusion MRI models can provide useful information for the differentiation between GBM and SBM. It can be observed that most of the perfusion MR parameters (relative cerebral blood volume, relative cerebral blood flow, relative Ktrans, and relative volume fraction of the interstitial space) clearly show higher gradient for GBM than SBM. GBM also demonstrates higher heterogeneity in the peritumoral edema and most of the perfusion parameters demonstrate higher gradients in the area closest to the enhancing tumor.
Conclusion:
Our results show that there is a difference in the perfusion parameters of the edema between GBM and SBM demonstrating a vascularization gradient. This could help not only for the diagnosis, but also for planning surgical or radiotherapy treatments delineating the real extension of the tumor.This studywas partially funded by SERAM (Spanish Society of Medical Radiology) Grant Becas Seram-Industria 2014.Aparici-Robles, F.; Davidhi, A.; Carot Sierra, JM.; Perez-Girbes, A.; Carreres-Polo, J.; Mazón-Momparler, M.; Juan-Albarracín, J....
