The linguistic time-series forecasting model (LTS-FM), which has been recently proposed, uses linguistic words of linguistic variable domains generated by hedge algebras (HAs) to describe historical numeric time-series data. Then, the LTS-FM was established by utilizing real numeric semantics of words induced by the fuzziness parameter values (FPVs) of HAs. In the existing LTS-FMs, just the FPVs of HAs are optimized, while the used word set is still chosen by human experts. This paper proposes a co-optimization method of selecting the optimal used word set that best describes numeric time-series data in parallel with choosing the best FPVs of HAs to improve the accuracy of LTS-FMs by utilizing particle swarm optimization (PSO). In this co-optimization method, the outer loop optimizes the FPVs of HAs, while the inner loop optimizes the used word set. The experimental results on three datasets, i.e., the "enrollments of the University of Alabama" (EUA), the "killed in car road accidents in Belgium" (CAB), and the "spot gold in Turkey" (SGT), showed that our proposed forecasting model outperformed the existing forecasting models in terms of forecast accuracy.

The aim of this study is to identify the most prolific countries in the field of special education and to discuss the widespread impact of their papers by taking into account the country's h-index. Through a bibliometric analysis, the data were collected in the Web of Science Core Collection category "Education, Special" in the Social Science Citation Index during 2011-2020. The 25 most prolific countries in the field of special education were determined in terms of paper productivity, and it was seen that the leading country was undisputedly the USA (54.42%). Meanwhile, a strong positive correlation was found between the h-index and the number of papers published by the countries (r=0.864). On the other hand, when the ranking in terms of the number of papers was reconfigured by the h-index, it was relatively changed. The possible reasons for this change for the countries with the most changing rankings were discussed by considering some definitive criteria such as the journal quartiles, the percentage of international and domestic, and the percentage of open access papers. This study reports a positive correlation between the quality and quantity in the field of special education for the publications of countries. It has been shown that where the positive correlation deviates, then especially, the journal quartiles, the percentage of international collaboration and the percentage of open access papers have a significant effect. The bibliometric findings may be useful to enrich the discussion about the widespread impact of papers and debate whether the use of h-index is acceptable for cross-national comparisons.

Introduction: European societies are rapidly becoming multicultural. Cultural diversity presents new challenges and opportunities to communities that receive immigrants and migrants, and highlights the need for culturally safe healthcare. Universities share a responsibility to build a fair and equitable society by integrating cultural content in the nursing curricula. This paper aims to analyze European student nurses´ experience of learning cultural competence and of working with patients from diverse cultural backgrounds. Materials and methods: A phenomenological approach was selected through a qualitative research method. 7 semi-structured focus groups with 5–7 students took place at the participants' respective universities in Spain, Belgium, Turkey and Portugal. Results: 5 themes and 16 subthemes emerged from thematic analysis. Theme 1, concept of culture/cultural diversity, describes the participants' concept of culture; ethnocentricity emerged as a frequent element in the students' discourse. Theme 2, personal awareness, integrates the students' self-perception of cultural competence and their learning needs. Theme 3, impact of culture, delves on the participants' perceived impact of cultural on both nursing care and patient outcomes. Theme 4, learning cultural competence, integrates the participants' learning experiences as part of their nursing curricula, as part of other academic learning opportunities and as part of extra-academic activities. Theme 5, learning cultural competence during practice placements, addresses some important issues including witnessing unequal care, racism, prejudice and conflict, communication and language barriers, tools and resources and positive attitudes and behaviors witnesses or displayed during clinical practice. Conclusion: The participants' perceived level of cultural competence was variable. All the participants agreed that transcultural nursing content should be integrated in the nursing curricula, and suggested different strategies to improve their knowledge, skills and attitudes. It is important to listen to the students and take their opinion into account when designing cultural teaching and learning activities. [ABSTRACT FROM AUTHOR]
