A two-stage LDA algorithm for ranking induced topic readability
2022
Probabilistic topic models, such as LDA, are standard text analysis algorithms that provide predictive and latent topic representation for a corpus. However, due to the unsupervised training process, it is difficult to verify the assumption that the latent space discovered by these models is generally meaningful and valuable. This paper introduces a two-stage LDA algorithm to estimate latent topics in text documents and use readability scores to link the identified topics to a linguistically motivated latent structure. We define a new interpretative tool called induced topic readability, which is used to rank topics from the one with the most complex linguistic structure to the one with the…
Il ruolo della comprensione del testo nel processo di matematizzazione e modellizzazione
2017
In questo articolo vengono analizzate le risposte fornite a un interessante item relativo alla Prova standardizzata di matematica somministrata nel maggio 2015 a tutti gli allievi di quinta elementare del Canton Ticino. A partire dai risultati statistici emersi da un campione di 508 protocolli selezionati, viene presentata un’analisi qualitativa effettuata su un campione più ristretto di 174 studenti di prima media, allo scopo di rintracciare le cause delle difficoltà emerse nella risoluzione. Da questa analisi si rileva come le risposte sbagliate di diversi studenti siano legate a difficoltà nella comprensione del testo dell’item, in particolare a difficoltà di interpretazione linguistica.…
Development of silent reading fluency and reading comprehension across grades 1 to 9 : unidirectional or bidirectional effects between the two skills?
2022
Purpose This study examines the developmental interplay between silent reading fluency and reading comprehension from Grade 1 to Grade 9 (age 7 to 15) in a large Finnish sample (N = 2,518). Of particular interest was whether the associations are bidirectional or unidirectional. Methods Children’s silent reading fluency and reading comprehension skills were assessed using group-administered tests, at seven time points, in Grades 1, 2, 3, 4, 6, 7, and 9. A random intercept cross-lagged panel model with latent factors was used to identify between- and within-person associations between silent reading fluency and reading comprehension. The use of latent factors allowed for the controlling of me…

Hacia una metodología del análisis crítico del discurso desde la enacción aplicada al género y la traducción: Una visión liminar en Bridget Jones. Ma…
2023
En esta investigación se abordan los presupuestos biológico-cognitivos de la Enacción y se refieren a un sistema lingüístico-perceptivo mediante la Gramática Liminar (GL) y el Análisis Crítico del Discurso (ACD) aplicado al estudio enactivo entre Bridget Jones. Mad about The Boy (2013) y Bridget Jones. Loca por él, de H. Fielding. Analizamos cómo la enacción sexista resulta de la forma sistémica de comunicarnos, incardinada en el cuerpo como matriz cognitiva biológica-cultural, donde el lenguaje actúa como bucle de retroalimentación en perpetua intratraducción entre el ser/mundo y viceversa, y se configura en lenguas de cuya intertraducción depende el grado de connotación sexista. This rese…
An Integrated Theory for the Accumulation of Mentally Ill Offenders and the Effect of Realignment in California
2018
High mental illness prevalence in California state prisons has drawn much attention of scholars and policymakers in the past three decades. Various studies suggest that the mental illness prevalence in prison has increased from 0.14 to 0.3 from 1987 to 2014. The problem with a high concentration of mentally ill prisoners culminated when the California Department of Corrections and Rehabilitation (CDCR) was sued for the violation of inmates’ rights under the Eighth Amendment in the early 1990s. Consequently, CDCR’s health care was placed under Federal receivership to reform prison health care. Receivership is an uncommon remedy adopts by a federal court when other court orders have failed to…
Influence of brand image of a sports event on the recommendation of its participants
2020
The aim of this research is to test the psychometric properties and relationships of a model where, from brand congruence of a sport event, trust and commitment to it can be generated, influencing future behavior of participants and resulting in a higher recommendation also called Word of Mouth (hereinafter WOM). A quantitative approach has been carried out by means of a validated questionnaire with Likert-type responses, and data were analyzed with the EQS 6.4 software. The findings indicated that the model is adequate, and also confirm that from congruence, we can explain, at a theoretical level, 45% of trust, and in the same way, from the congruence and trust, we can explain 67% of the c…
Describing a network using the ‘Resource-Competences, Organizations, Value’ Business Model
2021
International audience; The network literature reveals some trouble to reconciliate the ambivalence between individual and collective goals inside a network. The purpose of this research is to develop a tool to identify key insights of a network and associated organizations. In particular, following the Resource-Competencies Organization Value (RCOV) framework, this study identifies the contributions of each organization inside a network. Knowing the responsibility of each organization in their network’s strength and tensions could help to solve those ambivalences. Applied to a network, the Demil and Lecocq‘s (2010) RCOV Business Model, could reveal key inputs of a network that each organiz…
Teoría de la educación : educación y cultura en la sociedad de la información
2011
Se exponen las principales perspectivas en el estudio del comportamiento informacional: la perspectiva del usuario y la del sistema. En el primer caso, se asume una visión global del proceso de búsqueda de información y se desarrollan modelos teóricos y metodológicos para guiar la investigación en este campo. Se presentan como ejemplo la teoría del Sense-Making de Brenda Dervin y el modelo de Proceso de Búsqueda de Información de Carol Kuhlthau. En el segundo caso, se asume una perspectiva parcial del proceso de búsqueda de información, centrándose fundamentalmente en las transacciones entre usuario y el sistema o entre el usuario y la información. Se describen los estudios del uso de recur…
