Connexions bascocatalanes: les impersonals de subjecte suprimit
(Publicacions de l'Abadia de Montserrat, 2024) Fernández Fernández, Beatriz; Berro Urrizelki, Ane; Pérez Saldanya, Manuel
En aquest article analitzarem les impersonals de subjecte suprimit (ang. subject-suppressing impersonals; Blevins 2003), és a dir, les construccions amb un subjecte implícit i indefinit. Aques- tes construccions han rebut el nom de impersonals en basc (Rodet 1992; Ortiz de Urbina 2003; Fernández & Berro 2021) i s’han designat oracions pronominals de subjecte inespecífic en català (Bartra 2002). En totes dues llengües, aquestes construccions impersonals han estat considerades intransitives, ja que, en comptes de dos arguments, només se n’explicita un (o cap). Com a exponent de la intransitivitat d’aquestes construccions, en basc es fa servir l’auxiliar intransitiu izan ‘ser’ en comptes del transitiu *edun ‘haver’. En català, per la seva banda, aquestes construccions presenten el clític pronominal es. En aquest article tractarem de mostrar que, en aquestes construccions, el subjecte suprimit és sintàcticament actiu en totes dues llengües i que, per tant, les construccions poden ser considerades tipològicament com a impersonals de subjecte suprimit (Blevins 2003)
Benchmarking performance through efficiency analysis trees: improvement strategies for colombian higher education institutions
(Elsevier Ltd, 2024-04) Zofío Prieto, José Luis; Aparicio, Juan; Barbero Jiménez, Javier; Zabala Iturriagagoitia, Jon Mikel
We introduce benchmarking analysis based on state-of-the-art machine learning techniques applied to the measurement of efficiency to assess the performance of Higher Education Institutions (HEIs). We rely on Efficiency Analysis Trees (EAT) and its Convexified frontier counterpart (CEAT) to assess the efficiency of 144 private HEIs in Colombia and compare the results with those achieved with classical Data Envelopment Analysis (DEA). Both EAT and CEAT show a higher discriminatory power than DEA when determining efficiency scores. Our results identify the different splits of the production frontier, corresponding to each node of the efficiency tree, which groups HEIs according to specific management models. By identifying relevant peers for inefficient observations at the node level, we show which strategic guidelines can be adopted to improve the performance of each HEI. This process encourages mutual learning and suggests potential changes within each node leading to efficiency improvements
Optimal methodology for addressing the social impact component within project proposals and Curriculum Vitae
(Hipatia Press, 2024) Gutiérrez Fernández, Nerea; Zubiri Esnaola, Harkaitz; López de Aguileta, Garazi; Elboj Saso, Carmen; Soler Gallart, Marta; Flecha García, José Ramón
The scientific and grey literature have highlighted the increasing relevance of the social impact of research. More and more, funding and evaluation agencies are using social impact as a required criterion when assessing the excellence of research proposals and researchers’ CV. However, research has identified elemental confusions about what social impact is in most research proposals, CVs and consulting companies. Based on the communicative methodology which co-led the creation and elaboration of the priorities of social impact and co-creation, the study presented in this paper includes the knowledge co-created along years of dialogues with scientists and citizens and a documentary analysis of four official documents on social impact and researcher evaluation. Results identify the first scientific six guidelines to date on how to include researchers’ actual or potential social impact in the research proposals and CVs1) To avoid confusing social impact with dissemination or transference; 2) To identify the concrete social impact of the specific scientific knowledge created by the authors; 3) To precise the concrete indicators of each social impact; 4) To specify the concrete sources; 5) To identify the interactive social impact; 6) To include the potential social impact
A multi-site study on sex differences in cortical thickness in non-demented Parkinson’s disease
(Nature Research, 2024-12) Oltra, Javier; Segura, Barbara; Strafella, Antonio P.; Eimeren, Thilo; Ibarretxe Bilbao, Naroa; Díez Cirarda, María; Eggers, Carsten; Lucas Jiménez, Olaia; Monté Rubio, Gemma Cristina; Ojeda del Pozo, Natalia; Peña Lasa, Javier; Ruppert, Marina C.; Sala Llonch, Roser; Theis, Hendrik; Uribe, Carme; Junqué i Plaja, Carme
Clinical, cognitive, and atrophy characteristics depending on sex have been previously reported in Parkinson’s disease (PD). However, though sex differences in cortical gray matter measures in early drug naïve patients have been described, little is known about differences in cortical thickness (CTh) as the disease advances. Our multi-site sample comprised 211 non-demented PD patients (64.45% males; mean age 65.58 ± 8.44 years old; mean disease duration 6.42 ± 5.11 years) and 86 healthy controls (50% males; mean age 65.49 ± 9.33 years old) with available T1-weighted 3 T MRI data from four international research centers. Sex differences in regional mean CTh estimations were analyzed using generalized linear models. The relation of CTh in regions showing sex differences with age, disease duration, and age of onset was examined through multiple linear regression. PD males showed thinner cortex than PD females in six frontal (bilateral caudal middle frontal, bilateral superior frontal, left precentral and right pars orbitalis), three parietal (bilateral inferior parietal and left supramarginal), and one limbic region (right posterior cingulate). In PD males, lower CTh values in nine out of ten regions were associated with longer disease duration and older age, whereas in PD females, lower CTh was associated with older age but with longer disease duration only in one region. Overall, male patients show a more widespread pattern of reduced CTh compared with female patients. Disease duration seems more relevant to explain reduced CTh in male patients, suggesting worse prognostic over time. Further studies should explore sex-specific cortical atrophy trajectories using large longitudinal multi-site data
Cross-cultural adaptation, reliability and validity of the Spanish version of the long-term quality of life questionnaire

Purpose: The aim of this study was to translate, culturally adapt, and evaluate the psychometric properties of the Spanish Long-Term Quality of Life (LTQL) questionnaire. Methods: The LTQL was initially translated into Spanish and cross-culturally adapted based on established guidelines. The Spanish LTQL was administered to patients with breast cancer who had completed their initial treatment 5 years earlier, along with other self-report measures: Quality of Life in Adult Cancer Survivors (QLACS), Hospital Anxiety and Depression Scale (HADS) and EORT-QLQ-BR23. Reliability was evaluated using internal consistency and test-retest. Convergent and known-groups validity were examined. Structural validity as determined by confirmatory factor analysis (CFA) and Rasch analyses was used to assess the unidimensionality and item-functioning of the LTQL domains. Results: Cronbach’s alpha were above 0.7 in all domains. Test-retest coefficients were between 0.72 to 0.96 for LTQL domains. LTQL total score was correlated with others total scores of other measures: QLACS (r=-0.39), HADS depression (r=-0.57), HADS anxiety (-0.45) and EORTC-QLQ-BR23 (r=-0.50). CFA provided satisfactory fit indices, with RMSEA value of 0.077 and TLI and CFI values of 0.901 and 0.909, respectively. All factor loadings were higher than 0.40 and statistically significant (P<0.001). Rasch analysis showed that Somatic Concerns domain had 4 misfitting items, and Philosophical/Spiritual View of Life and social Support domains only 1 misfit item. However, unidimensionality was supported for the four domains. Conclusion: The findings support the validity and reliability of the Spanish version of LTQL questionnaire to be used in long-term cancer female survivors
