This study aims to develop a specialized and economically feasible educational model using a combination of conventional approach and additive technology with a precision that proves to be sufficient for educational use. With the use of computer-aided design/computer-aided manufacturing models in educational stages, the possibility of infectious diseases transmission can be significantly reduced.

The proposed process involves the planning and development of specialized anatomical three-dimensional (3D) models and associated structures using omnipresent additive technologies. A short survey was conducted among dental students about their knowledge of applying additive technologies in dental medicine and their desire to implement such technologies into existing curricula.

The results revealed how an educational 3D model can be developed by optimizing the mesh parameters to reduce the total number of elements while maintaining the quality of the geometric structure. The survey results demonstrated that the willingness to adapt to new technologies is increasing (p < 0.001) among students with a higher level of education. A series of recent studies have indicated that the lack of knowledge and the current skill gap remain the most significant barriers to the wider adoption of additive manufacturing.

An economically feasible, realistic anatomical educational model in the field of dental medicine was established. Additive technology is a key pillar of new specialized-knowledge digital skills for the enhancement of dental training.

The novelty of this study is the introduction of a 3D technology for promoting an economically feasible model, without compromising the quality of dental education.

This essay explores the effects of school buildings closure during the coronavirus disease 2019 (COVID-19) pandemic on Chilean teachers' and principals' professional role and values, highlighting implications for reconceptualizing educators' professionalism for the post-pandemic era.

Competing versions of Chilean educators' professionalism during the pandemic were analyzed based on government guidelines, national teachers' association statements, news reports and testimonies from teachers and principals collected from webinars.

The guidelines that the ministry issued after school building were required to close motivated educators to challenge a version of professionalism founded on new public management (NPM) policies, which mandated external control and emphasized students' academic outcomes. By challenging the dominant NPM perspective of professionalism, educators advocated for professional autonomy as well as students' and communities' well-being.

This essay offers insights into how the Chilean school system's response to the crisis evidenced competing notions of educators' professionalism. As the pandemic continues to be an ongoing phenomenon, four implications for reconceptualizing educators' professionalism are drawn, which could inform and offer guidance to practitioners and policymakers in the post-pandemic era.

The purpose of this paper is to deploy an export dependency index to identify the sectors and countries in Latin America which are most exposed to fluctuations in Chinese demand. Bilateral trade between China and Latin America has grown very quickly in the past decade. As a consequence, economic relationships with Latin America intensified tremendously, as growing demand for resources drove China into relatively unexplored frontiers.

The Index measures the relative exposure of Latin American exporters to shifts in demand from China and is scaled from 0 to 1 (the higher the score, the more exposed an exporter is to disruptions of trade with China). The authors undertook the analysis using six-digit trade figures from the United Nations COMTRADE database (Harmonized System 2007 nomenclature) to ensure granularity and consistency and contrasted their results across two points in time, 2008 and 2014. The analysis was very comprehensive, covering the products that accounted for 80 per cent or more of all exports to China in 2014, for all countries in Latin America and the Caribbean.

According to our estimates, dependency on China increased overboard across Latin America for all countries and all sectors between 2008 and 2014. Absolute dependency levels were highest in Costa Rica, Colombia, Uruguay, Venezuela, Brazil, Panama, Peru, Chile, Guyana and Argentina. Of these, the largest exporters to China, namely, Brazil, Argentina, Chile, Peru, Colombia and Venezuela, featured high dependencies concentrated around just four commodities: soy in the form of soybeans and soybean oil; crude oil; copper in the form of copper ore, copper cathodes and unrefined copper; and iron ore. These four commodities accounted for 80 per cent of the regions’ total exports to China.

This is one of few studies that look into Latin America’s commodity export dependency on China at such granular level.

This study aims to the effect of NaF, Li₂CO₃ and H₃BO₃ minerals was investigated, and the best mineralizer was found to be H₃BO₃. Furthermore, the effect of temperature was investigated, and the synthesized samples were calcined at temperatures of 1100, 1200 and 1300 °C to select the optimum calcination temperature.

This study was aimed at thoroughly investigating the effects of mineralizer addition and temperature on the synthesis of malayaite pink pigment based on raw materials of SnCl₂-SiO₂-Ca(OH)₂-K₂Cr₂O₇. To this end, the optimization of the synthesis parameters such as mineralizer addition and temperature was completely perused.

The optimum temperature was 1300 °C, and the color efficiency of pigments was evaluated by colorimetric (CIE L*a*b* system) analysis, and these parameters were close to those of industrial pigments.

To the best of the authors’ knowledge, for the first time, the effect of mineralizer addition and temperature on the synthesis of malayaite pink pigment was investigated through the sol-gel method. Herein, different parameters were optimized to propose a novel pigment with a much better performance.

The retail sector is not largely studied in Italy. The study offers a comparison between youth retail shift work in Milan and London. The aim of this paper is to contribute to the debate on the one hand on youth work and on the other hand to the debate on agency and structural factors in life planning, representation of the future and the transition to adulthood, observed in the United Kingdom's and Italian labour market. Even if the second one is a Southern European Country, these contexts are both characterised by a service-oriented economy and the widespread of precarious and flexible jobs.

Qualitative methods were used: one year of ethnographic observation, 50 interviews and two focus groups were carried out between 2015 and 2018 with retail workers and trade unionists. The contexts are Corso Buenos Aires in Milan, Italy, and Oxford Street in London, United Kingdom. Analysing young workers' discourses, the author identifies narratives that allow to grasp their present agency and imagined future.

Observing the crisis of the narrative (Sennett, 2020) allows to highlight the social consequences of working times on young workers' everyday life and future. The author argues that young workers struggle with the narrative of their present everyday life and the representation of the future. This relates to the condition of time alienation due to the flexible schedules and the fast pace of work in retail, both affecting the work-life balance.

The social consequences of flexible schedules in retail and fast fashion sector, which are new issues not yet sufficiently explored, are here investigated from the perspective of young workers. The study is focussed on the representations of young people working with customers in social and economic contexts characterised by flexible schedules and the deregulation of shop openings, the so-called 24/7 service society, not largely investigated in the sociological scientific literature, above all in the Italian context.

With an explosion of datasets available on the Web, dataset search has gained attention as an emerging research domain. Understanding users' dataset behaviour is imperative for providing effective data discovery services. In this paper, the authors present a study on users' dataset search behaviour through the analysis of search logs from a research data discovery portal.

Using query and session based features, the authors apply cluster analysis to discover distinct user profiles with different search behaviours. One particular behavioural construct of our interest is users' expertise that the authors generate via computing semantic similarity between users' search queries and the title of metadata records in the displayed search results.

The findings revealed that there are six distinct classes of user behaviours for dataset search, namely; Expert Research, Expert Search, Expert Explore, Novice Research, Novice Search and Novice Explore.

The user profiles are derived based on analysis of the search log of the research data catalogue in this study. Further research is needed to generalise the user profiles to other dataset search settings. Future research can take on a confirmatory approach to verify these user groups and establish a deeper understanding of their information needs.

The findings in this paper have implications for designing search systems that tailor search results matching the diverse information needs of different user groups.

We propose for the first time a taxonomy of users for dataset search based on their domain expertise and search behaviour.

This study aims to examine the evolution of the tourism supply chain (TSC) and its future development factors. To this end, a quantitative bibliometric analysis was conducted to provide insights from a statistical perspective, including the evolution of the TSC and an outlook on current characteristics and future research trends.

This paper presents a quantitative bibliometric study of selected papers on the Web of Science. The study of the evolution of the TSC is based on analyses of bibliographic coupling and co-occurrence of keywords.

Bibliographic coupling analysis identified 10 clusters defined by coherent groups of theoretical perspectives. The keyword analysis explains the occurrences in the TSC concept. It also helps to determine the future main drivers of TSC research. In the post-COVID-19 era, the tourism industry needs to focus on green transformation and new technologies to transform TSC, supply chain management and B2B relationships. It also needs to ensure employee retention and policies to attract new talent.

This study provides a comprehensive, objective and integrative overview of the evolution of TSC. It is one of the few original works on supply chain development and will be helpful for scholars and practitioners alike to understand the subject.

This study examines one of the managerial practices inspired by local value systems and ethics. The masaza system of governance is valued by the respective authorities in Uganda. Role clarity which is fundamental to social service delivery is one of the central tenets in the strategy. This calls for the adoption of role clarity in order to promote its application as an approach to effective service delivery. The masaza system in Buganda was applied under the guidance of the value and ethical arrangements of the Baganda people that reside in central Uganda and has been in use for a long period of time. Prior to colonisation, Buganda kingdom in central Uganda employed this structure of governance (ssaza-single/masaza-many) under the strict adherence to role clarity. The kingdom was divided into 18 administrative units (masaza). Each of which was under the stewardship of a head (owessaza), there were smaller units of eggombolola, omuluka, and obutongole whose roles were clearly defined to trickle down to the village level for equitable social service(s) provision. This study, therefore, examined the contribution of role clarity in promoting social service delivery in Uganda. The researchers used qualitative data, analysed and summarised information of vignettes to demonstrate the relevancy of applying role clarity in enhancing social services delivery in public institutions. The study concluded that role clarity influences social services in public institutions.

The purpose of this investigation is to analyze the role of perceived organizational support (POS) and intrinsic motivation in the relationship between high-performance work systems (HPWS) and job satisfaction.

The sample used in this study consists of 180 engineers from 25 companies. The model entails a cross-level moderated mediation process that was tested using multilevel structural equation modeling.

This research shows that the effect of HPWS via POS on job satisfaction is stronger among engineers with low intrinsic motivation than engineers with high intrinsic motivation.

Given the findings of this paper, organizations are advised to consider the importance of HPWS perceptions and intrinsic motivation to help strengthen engineer satisfaction.

This is the first study to provide evidence for the mediating effect of POS in the relationship between employees’ shared perceptions of the HPWS implemented at their companies and their job satisfaction, and the moderating role of employee intrinsic motivation in the relationship between POS resulting from HPWS and job satisfaction.

The current world is characterized by VUCAT (Volatility, Uncertainty, Complexity, Ambiguity, and Technology). These elements provoke in workers a need for leadership that must be addressed continuously (Deepika & Chitranshi, 2021). Companies must dedicate efforts to leading their employees in a homogeneous way for team integration (Contreras et al., 2020; Sandeep & Latasri, 2021). It should be noted that remote work is a permanent feature for more organizations. Despite the difficulties that workers at all levels have had to adapt to remote work, an adaptation has been achieved in general terms based on communication technology. However, in many cases, it has altered the traditional performance of resources in companies, which makes the leading global and local institutions design new rules in favor of the health of workers and, at the same time, contribute to their better performance. For that, managers in the areas of Human Resources, Finance, and Information Technology (IT) must be able to propose strategies to take care of the human capital of companies in all their departments. For the process to work efficiently, leadership is necessary. The transition of workers from the Asia Pacific region to teleworking, the influence of leadership, and the impact on job satisfaction, which is a measure that shows the optimal management of this new way of working in companies, are described. The organizational models related to business management, the barriers in the first steps of teleworking, the strategies used, the legislation created, and the results achieved by the company are described.
