As terminacións -anam e -anas en galego
Get PDFIn this work we study the results of the endings -ANAM and -ANAS in the municipality of Castrelo do Val, in the region of Verín, in the context of Galician and in the Galician-Portuguese dialect continuum. The data were obtained from our field research, ALGa, ALPI, NEnq and other research on Galician and Portuguese. We conclude that the reduction of the plural ending (-áns ˃ -ás) was firstly achieved by eliminating the final consonant in the singular form (-án ˃ -á). This explains why the westernising form -ns occupies a smaller territory than the singular variant -án. Changes recorded between the ALPI, ALGa, and NEnq surveys are small, and they show that there is a lot of linguistic continuity from 1934 to 2008, allowing us to see that the plural ending -ás and the singular form -á are slowly but surely gaining ground.Neste traballo estúdanse os resultados das terminacións -ANAM e -ANAS no concello de Castrelo do Val, na comarca verinesa, no conxunto do galego e no continuum dialectal galegoportugués. Os datos foron obtidos dunha indagación de campo propia, do ALGa, do ALPI, da NEnq e doutras investigacións sobre o galego e o portugués. Conclúese que a redución da terminación plural (-áns ˃ -ás) se deu primeiro cá eliminación da consoante final no singular (-án -˃ á). Isto explica que a forma occidentalizante -ns ocupe un territorio menor có da variante singular -án. Os cambios rexistrados entre as enquisas do ALPI, do ALGa e da NEnq son pequenos, mostran que hai moita continuidade lingüística de 1934 a 2008 e permiten ver que a terminación plural -ás e a singular -á gañan terreo moi devagar
A Cross-Lagged Panel Analysis of Reading, Writing, and Math in First-Grade Elementary Students
Get PDFThis longitudinal cross-lagged panel study, employing a data-driven approach, investigated the intricate relationships among reading, writing, and math during the learning process of first-grade elementary students. A sample of 392 first-grade students was selected, and assessments were conducted at three different time points: the beginning, middle, and end of the school year. The results revealed strong stability in the measures of reading, writing, and math across the three assessment points. Concurrent and temporal effects were analyzed, revealing bidirectional influences and underscoring the impactful role of reading. Model stability was assessed through resampling, which demonstrated consistency in a high percentage of configural vs. restricted comparisons, along with an RMSEA of less than 0.7. The educational implications of these findings are explored, emphasizing their relevance for enhancing learning processes in reading, writing, and math, particularly as concerns the interactions among these three domains.Este estudio longitudinal de panel con análisis cruzado, utilizando un enfoque basado en datos, investigó las relaciones entre la lectura, escritura y matemáticas durante el proceso de aprendizaje del alumnado de primer grado de primaria.

Efficacy of whole-body vibration on balance and motor function in children with osteogenesis imperfecta: A randomized controlled trial
Get PDFThe current study aimed to examine the influence of whole-body vibration (WBV) on balance and motor function in children with osteogenesis imperfecta (OI). This randomized controlled trial (single-blinded) included forty children with OI, aged 8 to 13 years. Two groups with equal numbers were randomly selected; the control group received 40 min. standard program of physical therapy while the WBV group received the identical program as the control group for 20 min. plus 20 min. of WBV training. The program was carried out for all children twice weekly for three successive months. Biodex Balance System was utilized to evaluate the dynamic balance by measuring the stability indices and Gross Motor Function Measure was employed to evaluate the motor function for two groups, pre and post intervention. Following intervention, results showed statistically significant improvements in all evaluated outcomes of both groups, with the favor of WBV group (p< 0.05). Incorporating WBV training into a standard program of physical therapy has a greater effect on dynamic balance and motor function than a standard program of physical therapy only among children with OI.The current study aimed to examine the influence of whole-body vibration (WBV) on balance and motor function in children with osteogenesis imperfecta (OI).

¿Pueden los consejeros delegados más capaces reducir la brecha entre la información interna y externa sobre RSE? Can more able CEOs reduce the gap between internal and external CSR disclosures?
No full textThis study examines the association between chief executive officer (CEO) ability and the gap between internal and external corporate social responsibility (CSR) disclosure. We find that a firm’s CSR disclosure gap decreases when its CEO's ability increases. We also find that this negative association is strengthened when a CEO has political connections and when a CEO is internally promoted (inside CEO). Our results are robust after controlling for firm fixed effect and addressing endogeneity concerns. Overall our findings are consistent with our argument that more able CEOs significantly reduce the CSR disclosure gap and maintain the positive relationship between internal and external stakeholders. These results carry substantial implications for both theory and practice. From a practical standpoint, our findings emphasize the pivotal role of capable CEOs in orchestrating consistent CSR narratives that resonate internally and externally. This study offers valuable insights for corporate leaders striving to enhance their firms' CSR transparency and maintain favourable stakeholder relationships.Este estudio examina la relación entre la capacidad del consejero delegado y la brecha entre la divulgación interna y externa de la responsabilidad social corporativa (RSC). Se observa que la brecha de divulgación de la RSE de una empresa disminuye cuando aumenta la capacidad de su consejero delegado. También observamos que esta asociación negativa se refuerza cuando el CEO tiene conexiones políticas y cuando es promovido internamente (inside CEO). Nuestros resultados son robustos tras controlar el efecto fijo de la empresa y abordar los problemas de endogeneidad. En general, nuestros resultados son coherentes con nuestro argumento de que los CEO más capaces reducen significativamente la brecha de divulgación de la RSC y mantienen la relación positiva entre las partes interesadas internas y externas. Estos resultados tienen importantes implicaciones teóricas y prácticas. Desde un punto de vista práctico, nuestras conclusiones subrayan el papel fundamental que desempeñan los directores generales capaces de orquestar narrativas de RSC coherentes que resuenen interna y externamente. Este estudio ofrece valiosas ideas a los directivos de empresas que se esfuerzan por mejorar la transparencia de la RSE de sus empresas y mantener relaciones favorables con las partes interesadas
Escalas sobre Responsabilidad Social Universitaria en estudiantes universitarios: una revisión de alcance
Get PDFUniversity Social Responsibility (USR) emphasizes the need for institutions to respond to societal challenges through increased engagement. For university students, this means adopting not only a broader professional perspective but also an understanding of the political, social, and economic dimensions. Therefore, implementing USR among university students is a crucial aspect of this process. The aim of this scoping review was to analyze the validation processes of USR scales applied to university students. The review identified 161 results, 17 of which met the inclusion criteria. Most of the research was conducted in Latin America. All studies employed a Likert scale to assess USR, with 13 studies conducting an exploratory factor analysis and all performing assessments of internal consistency or overall reliability. Overall, the validity and reliability of the scales showed satisfactory results, though only one study included a test-retest analysis. These findings underscore that USR has a vital role in cultivating competent and socially responsible professionals. Additionally, it can serve as a key differentiator for universities in a competitive landscape, enhancing initiatives that provide students with opportunities to engage in more mindful and collective-oriented behaviors.La responsabilidad social universitaria (RSU) es un concepto que enfatiza en las instituciones el cumplir con los requerimientos generados por los retos de la sociedad por medio de una mayor participación. Para el caso de los estudiantes universitarios esto implica una mirada más amplia del ámbito profesional que involucra la comprensión de las dimensiones políticas, sociales y económicas; por lo anterior, la implementación de la RSU en estudiantes universitarios es crucial en este proceso. El objetivo de esta revisión de alcance fue analizar el proceso de validación de escalas de RSU aplicadas a estudiantes universitarios. La revisión arrojó un total de 161 resultados, 17 de ellos cumplieron los criterios de inclusión. La mayoría de las investigaciones fueron aplicadas en Latinoamérica. Todos los estudios usaron una escala Likert para valorar la RSU. 13 investigaciones realizaron análisis factorial exploratorio y la totalidad llevó a cabo evaluaciones de consistencia interna o confiabilidad global. En general, la validez y confiabilidad de las escalas presentaron adecuados resultados; solo un estudio realizó prueba-reprueba. De esta manera se evidencia que la RSU conlleva un rol significativo en adoptar profesionales competentes, socialmente responsables y puede ser un diferenciador clave para las universidades en un entorno competitivo en el cual se fortalezcan iniciativas que otorguen oportunidades a los estudiantes de ejercer comportamientos más conscientes en el entorno colectivo
