Abstract

Purpose

This study investigates the relationship between social media use and loneliness among adolescents and the moderating role of media literacy in this relationship.

Design/methodology/approach

This study utilizes secondary cross-sectional data from the Korea Media Panel Survey conducted in 2021 by the Korea Information Society Development Institute. The sample comprised 480 Korean adolescents aged 13–18 years who had experience using social media.

Findings

The results showed that social media use was positively associated with adolescents’ loneliness and that media literacy moderated this relationship. Adolescents with low media literacy felt lonelier with increased social media use, while those with high media literacy felt less lonely as social media use increased. For those with average media literacy, social media use had no effect on loneliness.

Originality/value

The findings suggest that media literacy can serve as a protective factor against the negative effects of social media use, in particular, adolescent loneliness. This study underscores the importance of media literacy education and interventions by parents, educators and policymakers for adolescents.

Abstract

Purpose

The purpose of this paper is to investigate the factors influencing small and medium enterprises’ (SMEs) adoption of innovation approaches.

Design/methodology/approach

The methodology involves two steps. First, all the variables relevant to the adoption of innovation in SMEs are identified. Subsequently, primary data are gathered from decision makers of 213 SMEs, and a multinomial logistic regression analysis is performed.

Findings

The results indicate that SMEs adopt both open innovation and closed innovation approaches. The firm-level factors such as firm age, firm size, education qualification, work experience and culture, and external factors such as customers, competition, technological advances and ecosystem influence adoption of open innovation approach compared to closed innovation approach. Factors such as culture among firm-level factors and competition among external factors influence the adoption of closed innovation approach.

Practical implications

The study helps the managers or the decision makers of the SMEs to know the suitable factors influencing the firm to adopt innovation which could potentially help the firms in their business strategy.

Originality/value

The study explores the adoption of innovation approaches of SMEs in emerging economies. The outcomes of this research have far-reaching implications for theory and practitioners in emerging economies.

Abstract

Purpose

The purpose of this paper is to investigate the application of the postponement strategy by wineries in the state of Minas Gerais (Southeastern Brazil), in order to identify the types of postponement adopted by these companies, the implementation process and the results obtained after their adoption.

Design/methodology/approach

Twelve exploratory case studies were conducted in wine-producing companies, as well as on-site visits and semi-structured interviews with the managers of the companies surveyed.

Findings

The adoption of form postponement was verified in the companies studied mainly for table wine production, occurring most commonly during the bottling and labeling stages.

Research limitations/implications

This paper analyzed the application of the postponement strategy in Southeast Brazil. Future research should analyze the application of this strategy in other regions of the country and abroad.

Practical implications

The information acquired in this research can contribute to a more adequate practical application of the postponement strategy in a little-known industry sector.

Originality/value

In addition to discussing and verifying the application of the postponement strategy in the wine industry, this research presents information to assist in its implementation, use and consolidation.

Abstract

Purpose

The purpose of this paper is to present and apply a parasitic extraction approach for the calculation of DC busbar inductances.

Design/methodology/approach

A computational approach based on the finite integration technique and computed magnetic energy is developed to extract parasitic inductances. The finite integration analysis is conducted via the magnetoquasistatic solver of CST EM Studio® capturing the 3D geometrical effects of the design, as well as the skin and proximity effects.

Findings

The method is applied successfully to evaluate the leakage inductances of two printed circuit boards structures; a backplane sample for the verification purpose and a real DC bus employed in a three‐phase pulse width modulation inverter.

Research limitations/implications

The paper demonstrates that the method calculates the loop inductances accurately. It does not, however, verify the used technique to split loop inductances into partial inductances.

Practical implications

The extraction method is easy‐to‐use and able to handle complex geometries within acceptable computation time and accuracy.

Originality/value

The paper introduces a way to compute the parasitic inductances from the results of a numerical electromagnetic field solver.

Abstract

Purpose

Digital literacy is not the mere ability to use a digital device or know to use various software. It is a domain of exploration for sociology, psychology, education and, of course, technology. This study aims to present a quantitative analysis of the literature on digital literacy using a bibliometric approach.

Design/methodology/approach

Using data from the Web of Science database, the importance of the research is evaluated by reviewing 2307 publications and examining the yearly publication, field category productivity, citation structure, most cited resources, documents, most-cited authors, most productive authors, and country in the field of digital literacy. Further, a cluster analysis is conducted to see the most recurrent keywords and emerging trends in this field. At last, the authors analyzed the thematic progression of keywords over these five years based on the normalized citations. Additionally, a graphical representation of the bibliometric data using VOSviewer is presented in the paper.

Findings

The results suggest a steady rate of publication in this field, with most of the research published in education and library fields and the USA leading the country in this realm. The emerging themes in this field are ‘Fake News’, ‘Competence’, ‘Educational Technology’, ‘Health Literacy’, ‘Self-Efficacy’ and, interestingly, ‘COVID-19’. The results also revealed that COVID-19 has been examined and associated with fake news, higher education, social media and information literacy.

Originality/value

This paper provides an overall summary of the most recent research work published from 2017 to 2021 on digital literacy in the backdrop of COVID-19. The study presents the thematic progression over the years and particularly the new keywords that emerged in the limelight of the pandemic. It contributes by updating the existing body of knowledge in the field of digital literacy and presents preliminary results related to COVID-19.

Abstract

While in some districts having drinking water is a given reality, there are others where there is a lack of access to this resource. Unfortunately, even today, 10.2% of the world population lives this situation and it could be worse in the coming years, according to UNICEF. Inhabitants in Pamplona Alta at southern Lima, Peru, daily suffer this harsh reality. This social challenge study attempts to define a methodology for an effective logistic planning of water distribution in Torres Minas. Currently, they obtain it from unsanitary and informal vendors. This chapter provides the basis of a new layout of the water distribution network based on clusters to efficiently satisfy water demand. Specifically, we propose the use of orderly delivery points called “bus-stops of water” in a two-echelon distribution system, whose optimization relies on a mixed-integer linear programming (MILP) technique. The objective of these guidelines is minimizing the transactional and transportation cost, while increasing the bargaining power of the community. Results showed a reduction of 52.67% and 26% in transactional and transportation costs, respectively, and a reduction of the associated risks of shortage and contamination of a tight delivery of water. Moreover, we foster the application of this methodology in other similar situations to produce sustainable growth for human settlements; regardless, there is a lack of access to water or a steep geography.

Abstract

Purpose

The purpose of this study is to present an overview of the existing knowledge on the combined application of lean, off-site and simulation (LOS) in housing delivery.

Design/methodology/approach

A systematic literature review approach was adopted. Based on a comprehensive search using Scopus, Web of Science and the International Group for Lean Construction databases, 66 relevant journal articles were identified and analysed.

Findings

This study found that the most significant impacts of the combined application of LOS in housing delivery are the capacity to visualise the production processes as a whole in real time, exposure and removal of non-value-adding activities from the production and faster delivery. However, the combined application of LOS is low compared to a single application of each technique in housing delivery.

Practical implications

The results provide relevant stakeholders and actors in the housing sector (private and public housing developers, off-site housing manufacturers and constructors, housing associations and government housing agencies, among others) with the information needed to improve the outcomes of housing delivery through the application of LOS.

Originality/value

This study contributes to the ongoing debate on addressing the global housing shortage by presenting an integrated overview of the existing knowledge on the impact of the nexus of LOS and providing compelling evidence for its usage in housing delivery. It also demonstrates how the combined application of LOS supports the achievement of the flow and value view in the transformation flow value model, which was not previously reported.

This study aims to investigate the factors influencing the data sharing habits of psychologists with respect to academic reciprocity.

Abstract

Purpose

This study aims to investigate the factors influencing the data sharing habits of psychologists with respect to academic reciprocity.

Design/methodology/approach

A research model was developed based on Ostrom’s (2003) theory of collective action to map psychologists’ underlying motivations for data sharing. The model was validated by data from a survey of 427 psychologists, primarily from the psychological sciences and related disciplines.

Findings

This study found that data sharing among psychologists is driven primarily by their perceptions of community benefits, academic reciprocity and the norms of data sharing. This study also found that academic reciprocity is significantly influenced by psychologists’ perceptions of community benefits, academic reputation and the norms of data sharing. Both academic reputation and academic reciprocity are affected by psychologists’ prior experiences with data reuse. Additionally, psychologists’ perceptions of community benefits and the norms of data sharing are significantly affected by the perception of their academic reputation.

Research limitations/implications

This study suggests that Ostrom’s (2003) theory of collective action can provide a new theoretical lens in understanding psychologists’ data sharing behaviours.

Practical implications

This study suggests several practical implications for the design and promotion of data sharing in the research community of psychology.

Originality/value

To the best of the authors’ knowledge, this is one of the initial studies that applied the theory of collective action to the mechanisms of reputation, community benefits, norms and reciprocity in psychologists’ data sharing behaviour. This research demonstrates that perceived community benefits, academic reputation and the norms of data sharing can all encourage academic reciprocity, and psychologists’ perceptions of community benefits, academic reciprocity and data sharing norms all facilitate their data sharing intentions.

Abstract

Purpose

Most of the research on collaborative consumption platforms (CCPs) has focused on motivational drives, and little research has been conducted on the problem of unbalanced information sharing, also known as the “lemons problem,” and signals. The paper aims to discuss these issues.

Design/methodology/approach

This study conducted a netnography and an experiment.

Findings

The netnographic study showed that participants tend to use low ratings and negative reviews as cues implying more searches, use ratings as an anchor to adjust other information, and employ differing cognitive information-processing styles. The experimental results show that, in a normal environment (when ratings are high), visualizers (verbalizers) have more of an intention to use CCPs when they are exposed to abundant pictures (textual cues); however, when the cues lead to a further information search (when the ratings are low), this search behavior pattern is reversed: visualizers (verbalizers) have more of an intention to use CCPs when they are exposed to abundant textual cues (pictures).

Research limitations/implications

This study extends previous research by showing that people frequently use differing heuristics depending on the context; that ratings have an anchoring effect and guide people in selecting a signal to use and condition how they use it; and that visualizers prefer text cues to pictorial cues when trying to make informed decisions under a condition that points to a further information search. These results are opposite of previous assertion.

Practical implications

Marketers are advised to provide a mechanism by which users can extract the cues they need and reduce the less urgent ones; devise a mechanism that screens participants and divides them into two categories: those who post honest evaluations and those who do not; and reduce the opportunistic behaviors of partners on both sides.

Originality/value

The current study addresses consumers’ use of information posted by other consumers on CCPs and demonstrates that participants use low ratings and negative reviews as cues implying more searches, use ratings as an anchor to adjust other information, and employ differing cognitive information-processing styles. Previous research rarely addressed these information search behaviors of consumers on CCPs.
