Abstract

Purpose

Ventilation of indoor spaces is required for the delivery of fresh air rich in oxygen and the removal of carbon dioxide, pollutants and other hazardous substances. The COVID-19 pandemic brought the topic of ventilating crowded indoors to the front line of health concerns. This study developed a new biologically inspired concept of biomimetic active ventilation (BAV) for interior environments that mimics the mechanism of human lung ventilation, where internal air is continuously refreshed with the external environment. The purpose of this study is to provide a detailed proof-of-concept of the new BAV paradigm using computational models.

Design/methodology/approach

This study developed computational fluid dynamic models of unoccupied rooms with two window openings on one wall and two BAV modules that periodically translate perpendicular to or rotate about the window openings. This study also developed a time-evolving spatial ventilation efficiency metric for exploring the accumulated refreshment of the interior space. The authors conducted two-dimensional (2D) simulations of various BAV configurations to determine the trends in how the working parameters affect the ventilation and to generate initial estimates for the more comprehensive three-dimensional (3D) model.

Findings

Simulations of 2D and 3D models of BAV for modules of different shapes and working parameters demonstrated air movements in most of the room with good air exchange between the indoor and outdoor air. This new BAV concept seems to be very efficient and should be further developed.

Originality/value

The concept of ventilating interior spaces with periodically moving rigid modules with respect to the window openings is a new BAV paradigm that mimics human respiration. The computational results demonstrated that this new paradigm for interior ventilation is efficient while air velocities are within comfortable limits.

Abstract

Purpose

The purpose of this study is to assess students’ perceptions of four teaching and learning (T&L) methods used in a blended learning Contract Law course, namely, frontal, written assignments, simulations and online asynchronous T&L.

Design/methodology/approach

Law students (n = 417) filled in an anonymous questionnaire on their relative satisfaction with the four methods and their preferences. Participation was voluntary. The questionnaire was administered at the end of term, in class, prior to the Covid-19 restrictions. The results were calculated using Statistical Package for Social Sciences.

Findings

The students preferred face-to-face T&L in class and ranked online T&L last. Notably, 84% preferred blended learning combining all four methods. These results suggest that the online T&L for this Contract Law course setting was unsuccessful and that teachers should experiment with blending various T&L methods to maximize learning effectiveness and students’ satisfaction.

Research limitations/implications

The results only reflect one course in one year among law students, thus affecting the generalizability of the findings. This is further exacerbated by the convenience sample and the fact that only one type of blending was evaluated. Overall, the findings indicated that the survey participants were not yet ready to embrace online T&L as a primary component of blended T&L.

Practical implications

This study Alternative online solutions should be sought to foster social learning when face-to-face learning is not feasible for reasons, such as geographic distance, students’ disabilities or the current pandemic that prohibits social gatherings. This conclusion is particularly pertinent with respect to the impact of Covid-19 on face-to-face learning. Designers of blended learning programs should listen more carefully to students’ voices, and bear in mind that minimizing face-to-face T&L for various reasons might jeopardize students’ satisfaction, which is likely to decrease learning effectiveness.

Social implications

It is important that students’ perceptions be considered when building future T&L programs, especially students’ need for collaborative and social learning.

Originality/value

This study assessed four T&L methods administered in one course during the pre-Covid-19 era. This setting, which is rare, enabled a real-life assessment of the effectiveness of these popular methods as perceived by students.

Abstract

Purpose

Despite the actual prevalence of diverse types of multimedia information, research on video news is still in an early stage. Improving the accessibility of video news seems worth investigating, therefore, the purpose of this paper is to present a new combination mode of video news text clustering and selection. This method is useful for sorting out and classifying various types of news videos and media texts based on sentiment analysis.

Design/methodology/approach

A novel system is proposed, whereby video news are identified and categorized into good or bad ones via the authors' suggested Hidden Markov Model (HMM) and Support Vector Machine (SVM) hybrid learning method. Actually, an exploratory video news sentiment analysis case study, conducted on various news databases, has proven that the feature‐selection‐combining method, encompassing the Information Gain (IG), Mutual Information (MI) and CHI‐statistic (CHI), performs the best classification, which testifies and highlights the designed framework's value.

Findings

In fact, the system turns out to be applicable to several areas, especially video news, where annotation and personal perspectives affect the accuracy aspect.

Research limitations/implications

The present work shows the way for further research pertaining to the personal attitudes and the application of different linguistic techniques during the classification.

Originality/value

The achieved results are so promising, encouraging and satisfactory, that they highlight the originality and efficiency of the authors' approach as an effective tool enabling to secure an easy access to video news and multi‐media texts.

Abstract

Purpose

This study aims to investigate the impact of various board characteristics on environmental innovation (EI) among companies listed on the STOXX Europe 600. It also examines the moderating role of CSR committees on the board–EI nexus.

Design/methodology/approach

The sample consists of companies listed on the STOXX Europe 600 index over 12 years (2011–2022). This study uses the Refinitiv Eikon database to evaluate the extent of EI. Panel data regression analysis is used, with two-stage least squares and lagged models used as robustness tests to control for endogeneity.

Findings

The results indicate that board independence and gender diversity significantly increase EI, whereas CEO duality negatively impacts it. Other board attributes, such as board size, show no impact on EI. In addition, the presence of CSR committees moderates these relationships, enhancing the positive effects of gender diversity and board independence and mitigating the negative impact of CEO duality.

Practical implications

This study provides valuable insights for policymakers and corporate strategists aiming to advance environmental responsiveness through strategic board composition and establishing CSR committees. Emphasizing the importance of board independence, gender diversity and CSR committees, the findings suggest practical pathways for enhancing the adoption of EI by creating governance structures that support sustainable practices.

Originality/value

To the best of the authors’ knowledge, this is the first study to examine the moderating role of CSR committees on the associations between board characteristics and EI. This research addresses a crucial gap in the current literature, enriching the understanding of corporate governance and sustainability. It provides critical insights for developing policies and strategies that promote EI through effective board composition and the implementation of CSR committees.

Abstract

What are the consequences of urban life in an ethno-nationally contested city? How do everyday practices confront municipal strategies that attempt to control such urban situations? Focusing on urban life in which daily negotiation of ethno-national differences occurs, this chapter considers the nuances of urban politics and the use and meaning of the urban space, i.e., the micro-politics and the social dynamic of place-making, and their role in the struggle for urban citizenship in an ethno-nationally mixed city. Discourse analysis and ethnographic encounters define the annual Holiday of Holidays festival in the Israeli–Palestinian neighborhood of Wadi Nisnas as integral to Haifa's strategy for promoting itself as a site of coexistence. The neighborhood serves the entire city in that its “Arab” urban space has become the emblem of that coexistence. This manipulation by the municipality is, however, not reinforced by urban regeneration and heritage management of the local Palestinian community. Nonetheless coexistence discourse is also employed by the residents themselves, suggesting a more nuanced understanding of the role of urban space in promoting the city, as well as of concepts of local identity and citizenship.

Abstract

Purpose

Misinformation on social media has become a great threat across the globe. Therefore, the authors aim to provide a comprehensive understanding of social media users' misinformation combating behavior, especially during the COVID-19 pandemic. Specifically, the authors merged the uses and gratifications theory, social cognitive theory and theory of prosocial behavior into one theoretical framework (e.g. information seeking, status seeking, entertainment and norms of reciprocity) to understand their effect on users' prosocial media sharing experience and misinformation self-efficacy to combat misinformation.

Design/methodology/approach

The authors collected data from 356 social media users through “Google Forms” during the third wave of coronavirus in Pakistan. Further, the authors applied structural equation modeling for hypotheses testing.

Findings

The authors noted that entertainment and perceived norms of reciprocity positively affect social media users' prior experience and misinformation self-efficacy to enhance their misinformation combating intention. However, information seeking positively affects social media users' prior experience and insignificantly affects their misinformation self-efficacy. Similarly, status seeking was noted to be insignificantly associated with social media users' prior experience and misinformation self-efficacy.

Research limitations/implications

The authors tested this model of misinformation combating intention in a developing country during the COVID-19 pandemic and noted that entertainment and status seeking motives are context-specific. Therefore, this study may likely benefit researchers, academicians and policymakers to understand the causal relationship between motivations and the behavior of combating misinformation on social media within a developing country.

Originality/value

In this study the authors merged three theories (e.g. uses and gratifications theory, social cognitive theory and theory of prosocial behavior) to understand information seeking, status seeking, entertainment and norms of reciprocity as the main motives for social media users' misinformation combating intention.

Abstract

Purpose

The aim of this study is to reveal the contribution that Journal of Business & Industrial Marketing has to scientific research and its most influential thematic work in B-to-B since its beginning in 1986 until 2015, in commemoration of the 30th anniversary.

Design/methodology/approach

The paper begins with a qualitative introduction: the emergence of the magazine, its origins, editorial and positioning. Subsequently, it is based on bibliometric methodologies to develop quantitative analysis. The distribution of annual publications is analyzed, the most cited papers, the keywords that are mostly used, the influence on the publishing industry and authors, universities and the countries that have the most publications.

Findings

The predominant role of the USA at all levels is highlighted. It also highlights the presence (given its size and population) of the countries of Northern Europe. There is great interest in appreciating the evolution of the number of publications that are always increasing which demonstrates the growing and sustained interest in these types of articles, with certain times of retreat (often coincide with economic crisis).

Research limitations/implications

The Scopus database gives one unit to each author, university or country involved in the paper, without distinguishing whether it was one or more authors in the study. Therefore, this may bring some deviations in the analysis. However, the study considers some figures with fractional counting to partially solve these limitations.

Practical implications

After observing the different perspectives of the journal’s production, it allows to give an objective view of the evolution that the Journal of Business & Industrial Marketing has had in the past 30 years.

Originality/value

It is part of the trend that several journals (Journal of Marketing, Journal of Public Policy & Marketing, Journal of Marketing Research, Journal of Business Research) made special sections to show progress and contribution of these journals to scientific research.
