Desarrollo de la competencia comunicativa intercultural en los cursos acordes con la metodología Aprendizaje Integrado de Contenidos y Lenguas impartidos en la lengua francesa a través del andamiaje docente
The increasing popularity of Content and Language Integrated Learning (CLIL) courses has attracted the attention of Chinese language educators. Many scholars have examined its functions of facilitating the development of content and language. However, intercultural communicative competence (ICC), as a core aspect of CLIL’s 4Cs (communication, content, cognition, and culture) framework, has been hardly analysed. Moreover, most studies on CLIL courses have been conducted in English-medium contexts, with scant attention paid to CLIL programs delivered in languages other than English. Drawing from sociocultural theory, this study aims to investigate how Chinese students develop ICC through teacher scaffolding in French-medium CLIL courses and their views on facilitating ICC in CLIL courses. The study collected data from a six-week classroom observation of twenty Chinese French-major undergraduates and interviews with seven of these students. The findings revealed that teacher scaffolding, i.e. explaining academic language, drawing on previous knowledge and linguistic scaffolding, helped to develop the participants' ICC. This research addresses the gap in understanding how teacher scaffolding can facilitate students' ICC development in a French-medium CLIL course, providing pedagogical guidance for CLIL teachers on how to promote ICC.
FUNDING INFORMATION. The study was funded by the Fundamental Research Funds for the Central Universities in China (1103-413000094) and Major Projects of China National Language Commission (ZDA145-2).La creciente popularidad de los cursos en metodología Aprendizaje Integrado de Contenidos y Lenguas Extranjeras (AICLE) ha llamado mucho la atención de los pedagogos del idioma chino. Muchos estudiosos han examinado sus funciones relativas a facilitar el desarrollo del contenido y el lenguaje. Sin embargo, como aspecto fundamental del marco de enseñanza de las 4Cs (comunicación, contenido, cognición y cultura) de AICLE, la competencia comunicativa intercultural (CCI) ha sido poco analizada. Además, la mayoría de los estudios en los cursos de AICLE han sido realizados en contextos de la lengua inglesa, con poca atención prestada a los programas de AICLE impartidos en idiomas distintos del inglés. Basándose en la teoría sociocultural, el presente estudio tiene como objetivo investigar cómo los estudiantes chinos desarrollan la CCI a través del andamiaje de los docentes en los cursos acordes con la metodología AICLE impartidos en francés, y sus puntos de vista sobre la facilitación de la CCI en dichos cursos. Este estudio recopiló los datos a partir de una observación de seis semanas en un aula con veinte estudiantes universitarios de la Filología Francesa, y de las entrevistas con siete de ellos. Los resultados revelaron que el andamiaje de los docentes, por ejemplo, el idioma académico explicativo, basándose en el uso de conocimientos previos y el andamiaje lingüístico, ayudaron a desarrollar la CCI de los participantes. Esta investigación aborda el vacío de la comprensión de cómo el andamiaje de los docentes puede facilitar el desarrollo de la CCI de los alumnos en un curso en metodología AICLE impartido en la lengua francesa, proporcionando orientación pedagógica para los docentes de AICLE sobre cómo promover la CCI
Disentangling the Relationship between Portfolio Homogenization and Transaction of Non-fungible Tokens
There has been an explosion in the popularity of Non-Fungible Tokens (NFTs), drawing attention from practitioners and scholars alike since 2021. Each NFT denotes a digital asset in the likes of an artwork, a tweet, or a video that is recorded on the blockchain with a unique identifying code. In turn, the emergence of NFTs has transformed the digital asset landscape. With the rapid growth of the NFT market, there is a concern that the market is becoming increasingly homogenized due to readily available blockchain technologies and relatively low costs of NFT mints. To this end, this study attempts to elucidate how NFT portfolio homogenization affects transaction volume and variation in the marketplace. Particularly, we collected and analyzed a dataset of 2,004 collections comprising 7,151,515 NFTs from OpenSea, a leading NFT platform. We discovered significant inverted U-shaped relationships between NFT portfolio homogenization and transaction variation and transaction volume
Spiking Semantic Communication for Feature Transmission with HARQ
In Collaborative Intelligence (CI), the Artificial Intelligence (AI) model is
divided between the edge and the cloud, with intermediate features being sent
from the edge to the cloud for inference. Several deep learning-based Semantic
Communication (SC) models have been proposed to reduce feature transmission
overhead and mitigate channel noise interference. Previous research has
demonstrated that Spiking Neural Network (SNN)-based SC models exhibit greater
robustness on digital channels compared to Deep Neural Network (DNN)-based SC
models. However, the existing SNN-based SC models require fixed time steps,
resulting in fixed transmission bandwidths that cannot be adaptively adjusted
based on channel conditions. To address this issue, this paper introduces a
novel SC model called SNN-SC-HARQ, which combines the SNN-based SC model with
the Hybrid Automatic Repeat Request (HARQ) mechanism. SNN-SC-HARQ comprises an
SNN-based SC model that supports the transmission of features at varying
bandwidths, along with a policy model that determines the appropriate
bandwidth. Experimental results show that SNN-SC-HARQ can dynamically adjust
the bandwidth according to the channel conditions without performance loss
Oral Cancer Screening Habits Performed by Registered Dental Hygienists
The purpose of this study was to assess if registered dental hygienists perform thorough and complete extraoral and intraoral assessments for cancer detection through the use of palpation techniques, visualization and adjunctive screening devices. Our goal was to assess if these exams are being performed routinely and thoroughly, and if not, what possible barriers to regular exams may exist. This study will determine if registered dental hygienists perform thorough and complete extra oral and intra oral assessments for cancer detection. If there is a lack of performance of extra oral and intra oral assessments, it is essential to determine the barriers that are preventing the hygienist from performing them. This information will be generalizable to all RDH’s
Facilitating Supplementary Innovation in the Digital Game Industry: The Role of Modding Toolkits
Game modifications (mods) developed by users are common in the digital game industry, serving as a form of user-driven supplementary innovation that enables game developers to extend the lifespan of their core games. Companies have recognized the strategic value of such innovation and offered official modding toolkits to support users’ endeavors. Nevertheless, the effects of modding toolkits on mod performance are not well understood, as extant literature is fragmented and descriptive, lacking an examination of the relationship between official modding toolkits and mod performance. This study plans to address this knowledge gap by analyzing official toolkit documents and behavioral data from platforms such as Nexus Mod and investigating the effects of modding toolkit features on mod performance. By advancing our knowledge of the supplementary innovation toolkit as a strategic approach in the digital game industry, the study is expected to provide valuable insights into extending product lifespan and utility
A one-year cost–utility analysis of resuscitative endovascular balloon occlusion of the aorta versus resuscitative thoracotomy with aortic cross-clamping for non-compressible torso haemorrhage
Introduction
Major trauma is a leading cause of death and disability in young adults, especially from massive non- compressible torso haemorrhage. The standard technique to control distal haemorrhage and maximise central perfusion is resuscitative thoracotomy with aortic cross-clamping (RTACC). More recently, the minimally invasive technique of resuscitative endovascular balloon occlusion of the aorta (REBOA) has been developed to similarly limit distal haemor- rhage without the morbidity of thoracotomy; cost–utility studies on this intervention, however, are still lacking. The aim of this study was to perform a one-year cost–utility analysis of REBOA as an intervention for patients with major traumatic non-compressible abdominal haemorrhage, compared to RTACC within the U.K.’s National Health Service.
Methods
A retrospective analysis of the outcomes following REBOA and RTACC was conducted based on the published literature of survival and complication rates after intervention. Utility was obtained from studies that used the EQ- 5D index and from self-conducted surveys. Costs were calculated using 2016/2017 National Health Service tariff data and supplemented from further literature. A cost–utility analysis was then conducted.
Results
A total of 12 studies for REBOA and 20 studies for RTACC were included. The mean injury severity scores for RTACC and REBOA were 34 and 39, and mean probability of death was 9.7 and 54%, respectively. The incremental cost- effectiveness ratio of REBOA when compared to RTACC was £44,617.44 per quality-adjusted life year. The incremental cost-effectiveness ratio, by exceeding the National Institute for Health and Clinical Effectiveness’s willingness-to-pay threshold of £30,000/quality-adjusted life year, suggests that this intervention is not cost-effective in comparison to RTACC. However, REBOA yielded a 157% improvement in utility with a comparatively small cost increase of 31.5%.
Conclusion
Although REBOA has not been found to be cost-effective when compared to RTACC, ultimately, clinical experience and expertise should be the main factor in driving the decision over which intervention to prioritise in the emergency context
