Electron beam is a way of radiation that can induce different reactions on polymers. The purpose of this work is to analyze the effect that the electron beam can produce on polyester fabrics.

Poly(ethylene terephthalate) (PET) fibres were treated at 0, 50, 100, 150, and 200 KGy. Later on surface modification was analyzed by Scanning Electron Microscopy (SEM) and Atomic Force Microscopy (AFM). Colorimetric and thermal measurements were studied too, as well as traction resistance.

Traction resistance showed no significant variations. As a result the authors could observe some changes in fabric witnesses and cristallinity increase, but no changes in traction resistance were observed. Moreover, when surface was studied, roughness was increased as oligomers moved towards fibre surface because of radiation dose.

The authors could appreciate roughness increased with radiation dose as well as yellowness and crystallinity.

The emerging industrial revolution referred to as Industry 5.0 is focusing on leveraging human creativity with intelligent and autonomous systems to derive user-friendly work environment for the businesses. Industry 5.0 stresses on people centric work ecosystem, zero accident policy and the well-being of labour within the production processes. This approach of Industry 5.0 to obtain human-centric safety solutions through the deployment of digital technologies deduces workplace accidents and costs leading to the development of Safety 4.0. This chapter aims to investigate the opportunities and challenges of Safety 4.0 and its enabling technologies aspiring towards the greater impact on safety management. Further, we have proposed a framework for the role of human centric digital transformations concerning safety in the manufacturing industry propelling Safety 4.0. Concluding, we discuss the implications for managers and practitioners. We found that Safety 4.0 will strengthen industrial safety, and instead of reacting to accidents, the concept evolved towards a preventive and proactive approach for a healthy industrial ecosystem.

This paper aims to draw up the state of scientific knowledge in the field of Formula 1 with relation to tourism and urban studies.

This study is based on a systematic review of the scientific literature regarding this issue. Using targeted keywords and the analysis of various documentary databases, 8,075 references were identified and 40 documents were analyzed in an exhaustive manner.

This study presents a very nuanced portrait of the urban and tourism impacts of Formula 1 on the host territories. In many of the studies analyzed, a gap may be noted, sometimes flagrant, between the development goals of the promoters of these mega-events and local realities. This study also highlights the fact that Formula 1 has established itself as a sports events industry that can renew and enhance the brand image of certain cities.

Very few recent studies have exhaustively reviewed the scientific literature published in English and French with regard to the field of Formula 1 from a tourism and urban perspective. This study makes it possible to identify the main analytical findings and research perspectives resulting from this scientific work while discussing them using a theoretical framework related to the hypermodern character of different societies.

The purpose of this paper is to present the evolution in notions from bibliometrics to altmetrics and confront them taking into consideration specific criteria. The objective of this paper is to present the evolution of research, regarding the above fields, the study of metrics and indicators used, and the strength and weaknesses resulting from the current literature. Furthermore, the authors present the manipulation techniques for both fields as their main weakness, as well as further key points, analyzing the alternative options of bibliometrics and altmetrics.

First, the authors present the evolution of the literature, concerning the specific field and metrics used, following with a brief description of basic indicators related to the field of bibliometrics (journal impact factor (JIF), eigenfactor, article influence score and h-index) discussing their advantages and disadvantages. In the second part, the authors describe altmetrics and present the differences with bibliometrics.

Both bibliometrics and altmetrics remain weak indicators as fraught with disadvantages with manipulation being the greatest of all. Nevertheless, the combination of the two is proposed in order to export safer conclusions on assessing the impact. Regarding the manipulation there is yet not a clean technique to eliminate manipulation. In specific, regarding bibliometrics, the manipulation of indicators refers only to the human factor intervention. The theoretical implication of this study constitutes of collecting the relevant literature regarding scientific indicators.

We must consider the study of new indicators, which combine metrics and methodologies used in both bibliometrics and altmetrics. The theoretical implication of this study constitutes of collecting the relevant literature regarding scientific indicators. Therefore, researchers are encouraged to test the proposed propositions further.

The practical contribution, on the other side, provides scholars with the knowledge of how making their work more accessible, increasing their impact.

The authors add to the originality by providing a framework of the relevant literature for bibliometrics and altmetrics for future researchers. The authors describe altmetrics and present the differences with bibliometrics. The authors conclude the research with the implications of the conducted analysis and the potential directions for future research. Regarding manipulation, the authors provide with the techniques so researchers are aware of the methods in order to protect their academic profile.

This paper presents recently published resources on library instruction and information literacy. It provides an introductory overview and a selected annotated bibliography of publications covering various library types, study populations and research contexts. The selected bibliography is useful to efficiently keep up with trends in library instruction for busy practitioners, library science students and those wishing to learn about information literacy in other contexts.

This article annotates 424 English-language periodical articles, monographs, dissertations, theses and reports on library instruction and information literacy published in 2021. The sources were selected from the EBSCO platform for Library, Information Science, and Technology Abstracts (LISTA), Education Resources Information Center (ERIC), Scopus, ProQuest Dissertations and Theses, and WorldCat, published in 2021 that included the terms “information literacy,” “library instruction,” or “information fluency” in the title, abstract or keywords. The sources were organized in Zotero. Annotations summarize the source, focusing on the findings or implications. Each source was categorized into one of seven pre-determined categories: K-12 Education, Children and Adolescents; Academic and Professional Programs; Everyday Life, Community, and the Workplace; Libraries and Health Information Literacy; Multiple Library Types; and Other Information Literacy Research and Theory.

The paper provides a brief description of 424 sources and highlights sources that contain unique or significant scholarly contributions.

The information may be used by librarians, researchers and anyone interested as a quick and comprehensive reference to literature on library instruction and information literacy within 2021.

The spatial development of urban areas affects the characteristics of landscape as well as people’s aesthetic perception of it. Specifically, sprawl results in an urban morphology which is diametrically opposed to the compact city model and which assumes several kinds of patterns: for example “striped”, “ribbon” or “leapfrogged” urban development. Assessing urban morphology in spatial terms is crucial to urban policy, while landscape metrics are the key to a comprehensive understanding of different urban development patterns. The purpose of this paper to design and test an urban morphology indicator (UMI) for the Lombardy Regional Landscape Plan.

The paper describes an UMI that can be used to identify the heterogeneity of built-up patterns according to urban porosity, fragmentation and patch shape. This UMI is a result of Esri ArcGIS 10.3 “grouping analysis” which works by applying a spatial statistical metric for clustering geometries in a given geographical area.

Morphological analysis was used in regional urban development policies with a view to minimising impact on surrounding ecosystems and preserving the natural environment and landscape. It defines 28 different urban morphology patterns in the region, which are divided into systems, polarities and urbanised units.

The proposed methodology differs from those traditionally used in qualitative/descriptive landscape planning and supports the identification of morphological features with quantitative statistical and spatial data, allowing a fine-scale assessment of complex metrics.

Continuous training in professional teaching competencies has become one of the challenges of the school of the 21st century, especially if we refer to the mastery of digital competence. The aim of this study is to analyze the degree of digital competence of secondary school teachers of different areas of knowledge during the global pandemic of COVID-19 in the Galician autonomous community and obtain data that allow us to infer whether there is an association between individual variables such as age, gender, degree, work experience and their mastery of digital competence.

A cross-sectional descriptive quasi-experimental study is performed using an accidental sample of secondary school teachers from different fields of knowledge.

The different results obtained determine that the level of knowledge and use of digital media and tools is low. There are no significant differences depending on the variables analyzed, but it is necessary to establish specific continuing education plans for the improvement of digital competence in secondary school teachers to enable the effective use and management of information and communication technologies in future professionals.

Therefore, the findings of this study allow the development of educational interventions focused on increasing the digital competence of teachers, taking into account their individual characteristics.

The purpose of this paper is to describe and analyse the methodology quality of the literature search protocols of systematic reviews and to assess the relevance of the search filter that applies PubMed for retrieving this type of publication of the MEDLINE database.

For the selection of the document type, a literature search about nutritional and metabolic diseases was carried out in MEDLINE and the PubMed filter was used for retrieving “Systematic Reviews”, selecting “Nutritional and Metabolic Diseases” from the Medical Subject Headings (MeSH) database as Major Topic to determine the area of knowledge. Data analysis was carried out using “External Logistic Biplot”, a novel multivariate statistical technique in the field of medical documentation.

The results highlight the large variability of the methodology used in the literature search protocols of the systematic reviews analysed and confirm the low precision of the filter used by PubMed for the recovery of systematic reviews.

The Logistic Biplot used in this research allows an optimal categorization of the different documentary typologies and classifies the documents by their methodological quality, demonstrating its usefulness for the future development of the bibliometric analysis.
