Abstract
Purpose
This study aims to investigate the scientific impact of additive manufacturing in recent years, considering its evolution as an Industry 4.0 technology and also in the current context of Industry 5.0. For this aim, advanced statistics and scientometric tools have been used.
Design/methodology/approach
This study aims to explore the trends and impacts of additive manufacturing, focusing on its evolution and its relationship with Industry 4.0 and 5.0. For this purpose, a scientometric study and a meta-analysis of data extracted from the scientific Scopus database have been carried out. R programming and specific bibliometric software have been used to conduct the research. Initially, the data were evaluated from various perspectives, including sources, topics and impact indexes, to assess trends derived from the volume of publications, the impact of sources and affiliations, as well as the production segmented by country and the relationships between authors from different countries. Subsequently, a meta-analysis on keywords has been carried out using two distinct clustering methodologies: link strength and fractionalization. The results obtained were compared to establish a specific taxonomy of the AM subtopics, considering AM as a single body of knowledge related to Industries 4.0 and 5.0 paradigms. The analyses carried out have shown the impact and strong evolution of additive manufacturing as a field of knowledge at the world level, both from the point of view of manufacturing processes and from the point of view of materials science. In addition, some differences have been detected depending on the country. As a result of the meta-analysis, four different subtopics have been detected, some of which are highly related to other technologies and approaches in Industries 4.0 and 5.0 paradigms. Additionally, it establishes a comprehensive taxonomy for AM research, serving as a foundational reference for future studies aimed at exploring the evolution and transformative impact of this technology.
Findings
The analyses carried out have shown the impact and strong evolution of additive manufacturing as a field of knowledge at the world level, both from the point of view of manufacturing processes and from the point of view of materials science. In addition, some differences have been detected depending on the country. As a result of the meta-analysis, four different subtopics have been detected: one of them directly related to the use of recently developed Industry 4.0 technologies in additive manufacturing. The results provide a starting point for prospective studies to understand the evolution and disruption of this technology.
Originality/value
The paper is original and is based on data systematically extracted from scientific databases. Then, a specific methodology based on different advanced tools was applied for scientometric evaluation and meta-analysis.

Abstract
Purpose
This paper seeks to analyse the internal materials flow in lean manufacturing in an assembly line of the Bosch factory, located in Spain. The objective is to develop a handling system in a small space, capable of solving the problems of accumulated intermediate stocks of parts. An improvement is proposed adopting the milkrun handling system, while verifying the advances by means of lean metrics.
Design/methodology/approach
Based on this case study, the paper identifies data from value stream mapping and uses lean metrics, such as dock‐to‐dock time and lean rate. The case study develops a timetable and routing analysis for the milkrun to improve materials flow.
Findings
The proposed logistics allows an improvement of lean metrics, without modifying the layout and production planning. The routing flexibility of the milkrun reduced stocks, work‐in‐process and dock‐to‐dock time, while increasing lean rate.
Research limitations/implications
The findings are limited due to the focused nature of the case study. Although the solution is designed for a particular plant, the methodology is fully exportable.
Practical implications
The paper shows a real case study illustrative for systems management. This research shows significant benefit associated with the implementation of lean programs.
Originality/value
It details how the application of lean manufacturing tools could necessitate a study of materials handling to improve lean metrics.

Abstract
What is the present state of international disaster relief? Seeks to answer this important inquiry because the increased emphasis on prevention does not make post‐disaster response unnecessary. In so doing, this article will explore three important questions. Have practitioners overcome the obstacles to effective and efficient relief which have been identified in previous studies? What problems remain? What are the solutions to those issues which have not been resolved? Suggests numerous opportunities for improvement in both disaster management and scholarship.

Abstract
Purpose
The purpose of this study is to identify the most frequent themes related with social media governance in government by year, analyzing if these themes have evolved over time, as well as highlighting the main risks and challenges found as further research opportunities.
Design/methodology/approach
First, the authors have extracted 431 abstracts from Scopus database. Then, abstracts were grouped by year to apply topic modeling to discover the underlying topics. Specifically, the authors have applied latent Dirichlet allocation algorithm to identify the most frequent topics by year.
Findings
The results reveal 19 important topics related with social media governance in government. Then, these topics were assigned to each year to identify the evolution of the research themes over the years, proposing interesting avenues for further research based on the identification of the main risks and challenges.
Practical implications
The proposed research methodology can be applied not only for research purposes but also to discover themes in any discourse with applications in politics, marketing, business, etc. In addition, it can be used to save time and costs analyzing citizen comments in public debates to identify the most important topics.
Originality/value
This study can serve to highlight gaps in the literature, opening the possibility that researchers can adequately position their inquiries, as well as to be aware of overstudied themes to pay less attention to them in future projects. In addition, the results of this study could serve as a starting point for other researchers to analyze connections between topics, propose theories that explain what was found and validate them in future studies.

Abstract
Purpose
Late in 2019, massive protest demonstrations rocked both Chile and Colombia. They were an expression of discontent with the economic model and social policies implemented in both countries in recent decades. The purpose of this study is to investigate how Chilean and Colombian news websites framed these social protests and what aspects of the social movements promoted these media to public opinion.
Design/methodology/approach
The methodology of this research is empirical; the authors use quantitative and discourse analysis techniques to study the news published by the top three most visited main news websites in each country and deduce the main frameworks emerging from them. After analyzing the framing of reality by media in 4,252 news items, the authors suggest that the main news portals in these Latin American countries not only portrayed the collective actions but also promoted interpretations that did not necessarily reflect the demands of the demonstrations.
Findings
The findings were that in the 2019 protests in Chile and Colombia, the media approach to collective action was not necessarily positive for the activists. This was mainly because framing in the Chilean and Colombian websites had to do with negative aspects of the movements, such as violence or economic costs.
Originality/value
The originality and value of this research is that despite the fact that there are abundant case studies on the relationship between social movements and media framing in the literature, this study adds to the current knowledge because it compares two Latin American countries and focuses on Web news portals.

Abstract
Purpose
The purpose of this paper is to examine gender differences in lifetime substance use and non-substance use (non-SUD) psychiatric disorders among illicit drug users and determine factors associated with non-SUD psychiatric disorders independently for males and for females.
Design/methodology/approach
Secondary analysis of five cross-sectional studies conducted in Barcelona, Spain during 2000-2006. Lifetime DSM-IV substance use and non-SUD psychiatric diagnoses were assessed using the Spanish Psychiatric Research Interview for Substance and Mental disorders (PRISM) among 629 people who use substances (68 per cent male) recruited from treatment (n=304) and out of treatment (n=325) settings. Odds ratios (OR) and 95% confidence intervals (CI) were calculated using binary logistic regression.
Findings
The prevalence of any lifetime psychiatric (non-SUD) disorder was 41.8 per cent, with major depression (17 per cent) and antisocial personality disorder (17 per cent) being the most prevalent disorders. After adjusting for age and study, the odds of having any lifetime non-SUD (OR 2.10; 95%CI 1.48, 2.96); any mood disorder (OR 2.13; 95%CI 1.46, 3.11); any anxiety disorder (OR 1.86; 95%CI 1.19; 2.92); any eating disorder (OR 3.09; 95%CI 1.47, 6.47); or borderline personality disorder (OR 2.30; 95%CI 1.36, 3.84) were greater for females than males. Females were less likely than males to meet criteria for antisocial personality disorder (OR 0.59; 95%CI 0.36, 0.96) and attention deficit disorder (OR 0.37; 95%CI 0.17, 0.78).
Research limitations/implications
Psychiatric disorders are common among people who use substances, with gender differences reported for specific disorders. Gender-sensitive integrated treatment approaches are required to prevent and to address comorbidity psychiatric disorders among this population.
Originality/value
This secondary analysis of five cross-sectional studies included a large sample size allowing sufficient power to examine the differences between men and women. An additional strength of the methodology is the use of the gold standard PRISM which was used to assess disorders.

Abstract
Purpose
The access to the rare originals of the early Spanish colonial imprints of the Philippines remains problematic. The reference librarians often are restricted to directing the students and scholars to the secondary resources that are available both in print and as a part of the digital assets within the North American academic libraries. This paper aims to focus on the select primary source editions including select Spanish language colonial imprints that are available electronically on the Web along the Open Access. These Web-based resources serve as the reference tools for the early history of the Philippines and Southeast Asia. As many of these publications are rare and extremely expensive for most libraries, the Open Access resources serve as an aid to building a virtual collection of these items.
Design/methodology/approach
The author had to create a data set of the early imprints of the Spanish Philippines using several bibliographic resources. The data set will be submitted as an Appendix for this research paper. The author did both qualitative and quantitative analysis of the data set along with the voyant-based digital humanities approach for topic modeling.
Findings
The goals of this paper were to not only survey the early Spanish printing of the Philippines but also provide the reader with a somewhat complete picture of how the printing began in the Spanish Philippines, what kind of the first books were printed and how one can access them given their rarity and fragility. The collection building paradigms are undergoing significant shifts, and the focus of many academic libraries is shifting toward providing access to these items. As these items high-value low-use items continue to be part of the Special Collections, the access to these is problematic. The virtual collections thus serve as a viable alternative that enables further research and access. While the creators of these works are long gone, the legacy of the Spanish colonial domination, printing and the religious orders in the Philippines remain alive through these works.
Research limitations/implications
As this is an introductory paper, the author focused on the critical editions rather than providing a comprehensive bibliographic landscape of the presses that produced these editions. He also did not take into consideration many pamphlets that were published in the same period. He also did not consider the Chinese language publications of the Islands. The Chinese had been block printing since medieval times (Little, 1996). In the context of the Spanish Philippines, the Chinese migration and trade have been studied in detail by Chia (2006), Bjork (1998) and Gebhardt (2017). The scope of this paper also was centered toward building a virtual collection of these rare books.
Practical implications
Rare books are often expensive and out-of-reach for many libraries; the virtual collection of the same along the Open Access model represents an alternative to collect and curate these collections. The stewardship of these collections also acquires a new meaning in the digital milieu.
Social implications
This research paper will allow scholars to see past the analog editions and help them focus on curating a virtual collection. The questions of electronic access are often ignored when it comes to visiting and using them in a controlled environment of the reading room in the Special Collections. The author argues that one way to enable access to these rare and expensive books is to provide access to their digital counterparts. These digital/virtual surrogates of the originals will facilitate further research.
Originality/value
The author could not find similar research on the publications of the early Spanish colony of the Philippines.

This paper aims to examine how the level of corporate governance disclosures by Spanish universities is influenced by a set of variables.
Abstract
Purpose
This paper aims to examine how the level of corporate governance disclosures by Spanish universities is influenced by a set of variables.
Design/methodology/approach
To do this, the authors carried out a content analysis of the website disclosures of all Spanish universities identified by the Universities Rectors’ Conference in Spain.
Findings
Results show that the amount of corporate governance information disclosed by Spanish universities is far from being adequate and does not meet the stakeholders’ demands, as well as those requirements imposed by the law. The findings have revealed that the most influential variables associated with better disclosure levels of corporate governance information are the public–private status and institution size.
Originality/value
Compared to the private sector, the researchers have paid less attention to corporate governance disclosures in universities. In the Spanish university context, there is limited literature on the level of corporate governance disclosures.
