Abstract

Purpose

The beliefs about this subject of N = 223 secondary education teachers were collected through an ex post facto research method using a descriptive and correlational design and a 27-item questionnaire.

Design/methodology/approach

The arrival of online learning, in this case m-learning, to secondary education, has made educators in this stage incorporate digital resources, such as Smartphones or mixed reality (MR), to their classroom methodologies. The present study describes the results obtained in the project design, implementation and evaluation of MR materials in learning environments (PID2019-108933GB-I00). The starting general objective is to determine the perception of Compulsory Education teachers-in-training from the areas of Experimental Sciences, Engineering and Architecture, and Health Sciences, on the use of MR as a teaching tool under the m-learning modality.

Findings

The main conclusion obtained was that neither sex nor age had an influence on the use of MR in the classroom, and its use was determined by elements associated with the classroom methodology, such as collaborative work and attention to diversity, which took place in the education center.

Research limitations/implications

The main obstacle found when conducting the research was being able to access the general population of teachers-in-training in the aforementioned Master's program.

Originality/value

The value of the article lies in publicizing the knowledge that secondary school teachers have of MR and giving clues to create training actions that encourage its incorporation into the classroom methodology.

Abstract

Does a strong commitment to an exchange rate peg reduce the cost of financial capital to less developed countries? We use a sample of twelve Caribbean countries to examine the impact that the Eastern Caribbean Currency Union (ECCU), a currency board/monetary union, has in lowering the cost of borrowing to its members. Results from estimations on individual and pooled annual data from 1976–1999 indicate that membership in the ECCU, in addition to other policy variables, significantly reduces the cost of financial capital.

Abstract

We present Bayesian models for finding the longitudinal causal effects of a randomized two-arm training program when compliance with the randomized assignment is less than perfect in the training arm (but perfect in the non-training arm) for reasons that are potentially correlated with the outcomes. We deal with the latter confounding problem under the principal stratification framework of Sommer and Zeger (1991) and Frangakis and Rubin (1999), and others. Building on the Bayesian contributions of Imbens and Rubin (1997), Hirano et al. (2000), Yau and Little (2001) and in particular Chib (2007) and Chib and Jacobi (2007, 2008), we construct rich models of the potential outcome sequences (with and without random effects), show how informative priors can be reasonably formulated, and present tuned computational approaches for summarizing the posterior distribution. We also discuss the computation of the marginal likelihood for comparing various versions of our models. We find the causal effects of the observed intake from the predictive distribution of each potential outcome for compliers. These are calculated from the output of our estimation procedures. We illustrate the techniques and ideas with data from the 1994 JOBS II trial that was set up to test the efficacy of a job training program on subsequent mental health outcomes.

Abstract

Purpose

Heart Failure (HF) is one of the leading mortality causes in elderly people. The purpose of this study is to assess readmission rates and reasons in elderly patients with HF.

Design/methodology/approach

The authors explored medical records of elderly patients with HF (75 years and more) at Chapidze Emergency Cardiology Center (Georgia) from 2015 to 2019. The authors analyzed the structure of the cardiovascular diseases and readmission rates of hospitalized patients with HF (I50, I50.0 I50.1). A multivariate logistic regression model was used to identify factors, associated with readmission for any reason during 6–9 months after the initial hospitalization for HF.

Findings

The major complication of cardiovascular diseases in elderly patients is HF (68.6%). Hospitalization rates due to HF in elderly patients have increased in recent years, which is associated with the population aging process. This trend will be most likely continue. Despite significant improvements in HF treatment, readmission rates are still high. HF is the most commonly revealed cause of readmission (48% of all readmissions). About 6–9 months after the primary hospitalization due to HF, readmission for any reason was 60%. Patients had concomitant diseases, including hypertension (43%), myocardial infarction (14%), diabetes (36%) and stroke (8%), affecting the readmission rate.

Originality/value

HF remains an important problem in public health. During HF-associated hospitalizations, both cardiac and non-cardiac conditions should be addressed, which has the potential for health problems and disease progression. Some readmissions may be prevented by the proper selection of medicines and monitoring.

Abstract

Purpose

Develop a comprehensive framework for assessing the knowledge organization systems (KOSs), including the taxonomy of Wikipedia and the ontologies of Wikidata, with a specific focus on enhancing management and retrieval with a gender nonbinary perspective.

Design/methodology/approach

This study employs heuristic and inspection methods to assess Wikipedia’s KOS, ensuring compliance with international standards. It evaluates the efficiency of retrieving non-masculine gender-related articles using the Catalan Wikipedian category scheme, identifying limitations. Additionally, a novel assessment of Wikidata ontologies examines their structure and coverage of gender-related properties, comparing them to Wikipedia’s taxonomy for advantages and enhancements.

Findings

This study evaluates Wikipedia’s taxonomy and Wikidata’s ontologies, establishing evaluation criteria for gender-based categorization and exploring their structural effectiveness. The evaluation process suggests that Wikidata ontologies may offer a viable solution to address Wikipedia’s categorization challenges.

Originality/value

The assessment of Wikipedia categories (taxonomy) based on KOS standards leads to the conclusion that there is ample room for improvement, not only in matters concerning gender identity but also in the overall KOS to enhance search and retrieval for users. These findings bear relevance for the design of tools to support information retrieval on knowledge-rich websites, as they assist users in exploring topics and concepts.

Abstract

Purpose

Disinformation has become a latent risk for online audiences, specifically for minors who are commonly exposed to a wide variety of online content at a time they are developing cognitively and emotionally. This paper aims to offer insight on minors’ perception and the tools used by this age group to verify the content to which they are exposed while online.

Design/methodology/approach

Twelve focus groups were held in Spain between April and June 2021 with a total of 62 participants aged 11–17. Besides age, sex and socioeconomic group were variables taken into consideration to select the participants. A script covering the intended questions was used to structure the discussion.

Findings

Result analysis reveals that minors are excessively confident in their ability to identify false news and feel the need to share content with their online community as a means of participation in discussions or trending topics. Although WhatsApp family groups are seen as a source of misleading news, the study reveals that the family and traditional media (mainly television) act as sources of verification of fake news for minors. In general, minors opt for actions that require less initiative to contrast the content they consume on the internet.

Originality/value

This study produces new findings by further deepening the results of the first quantitative study on the relationship between minors and disinformation in Spain using qualitative method from conducting virtual focus groups.

Abstract

UNDER steady load conditions, materials in gas turbines are subject to various forms of static and alternating stresses. Changes in the operating conditions such as starting, load variations and shut down cause additional thermal stresses which limit the permissible rate of these changes in service. In stationary plants these effects can be minimized by adjustment of the starting and shut down procedure or by protection of the sensitive parts with a cooling flow. In gas turbines for propulsion purposes load changes are governed by external conditions, are more frequent and take place at a higher rate. The consequent thermal stresses are then referred to as thermal shocks. Various methods for testing the resistance of materials to thermal shocks have already been suggested and applied. However, they differ very widely, and no quantitative, or even comparable figures are available as yet.

Abstract

Purpose

This study aims to explore the main concerns and attitudes Basque adolescents have regarding online privacy. It analyzes their motivations for sharing private information and the kind of information they share. Likewise, it examines whether they consider the potential consequences of revealing certain information online and analyzes if there are any differences between the motivations and attitudes of young people from Gipuzkoa and Labourd.

Design/methodology/approach

For this study, three methods were combined to collect the data in 17 schools in the Basque provinces of Gipuzkoa and Labourd: a survey carried out among 1,133 students, out of which 242 also completed a diary and 482 took part in discussion groups.

Findings

The data from this research does not fully support the “youth cultures of disclosure” (James, 2009) in the Basque Country; however, some of these practices have been observed.

Originality/value

Time spent online by adolescents has increased sharply in recent years. This increase has brought with it concerns about youth’s level of awareness regarding online privacy. This is the first cross-border study conducted in the Basque Country addressing this topic (in the Basque Autonomous Community, administratively belonging to Spanish territory, and in the Northern Basque Country, administratively in French territory).
