This study aims to assess the sources of COVID-19 information respondents relied for COVID-19 pandemic information access and use, forms of misinformation and their influence on COVID-19 vaccine uptake hesitancy among frontline workers.

A Google Form developed questionnaire, distributed conveniently through link shared through WhatsApp groups was used to collect data from frontline workers from Dar es Salaam and Dodoma cities. Analysis was done using a binary regression analysis.

It was found that it was not the source that mattered for one to be hesitancy or not on COVID-19 vaccination, but the extent to which the information the source channels was manipulated or false.

Relying only Google Form questionnaire sent through a link on WhatsApp may have compromised the quality of information gathered and the quality of conclusion. Another study may have conducted through researcher administered questionnaire to a bigger sample to increase conclusion reliability and validity.

This study urges that to increase the COVID-19 vaccine uptake, it is important to ensure that the quality of information from the revealed dependable sources is checked to avoid possible consequential disquiet resulting from misinformation.

As the world is striving toward combating the COVID-19 or at least lessening its effects, this paper is of its own kind, using the theory of informative fictions to guide the assessment of the sources of information and the extent to which they influence misinformation on COVID-19 vaccine uptake hesitancy.

This paper aims to provide a systematic review of the academic literature on the determinants, processes and impacts of indigenous entrepreneurship (IE), highlights its contribution to current knowledge and identifies research gaps to guide future research.

Databases used in this study included Scopus, ABI, Business Source Complete, ProQuest and Emerald Insight. In total, 84 articles were included in the review.

The findings revealed that 33 studies were qualitative, 12 used a survey-based approach, 25 were conceptual and 14 used mixed approaches. The focus on theory-building research underlines the fact that more theory-testing research is needed in the future. In total, 38 studies were conducted in developed countries and 43 in developing countries. The findings indicated that IE was driven by many determinants such as family and clan ties, patriarchy and social stratification, government support and conducive entrepreneurial ecosystems. Processes related to policies, IE development programs, partnerships, expenditure mechanisms, equitable distribution of benefits and resource mobilization. The outcomes of IE included economic development, sustainability, increased indigenous economic participation, enhanced quality of life, self-determination and preserving cultural heritage.

The current paper has some limitations. Firstly, it focuses only on academic journals and excludes conferences, books and working papers. Secondly, it includes only English language academic articles. However, while the current systematic literature review (SLR) has these limitations, it presents a thorough view of the determinants, processes and impacts of IE. Future studies may consider other sources beyond academic journals and also include non-English publications, and this approach may identify interesting areas for future research.

Existing reviews of IE take a narrow perspective and fail to present a comprehensive view of the IE phenomenon. The current study aims to fill this gap in the literature and provides a SLR pertaining to IE’s determinants, processes and impacts. The review is both timely and relevant because it identifies gaps and serves as a springboard to guide future research.

The purpose of this study is to scrutinize the influence of individual learning styles on the effectiveness of augmented reality (AR)-based learning in structural engineering. There has been a lack of research examining the correlation between learning efficiency and learning style, particularly in the context of quantitatively assessing the efficacy of AR in structural engineering education.

Using Kolb’s experiential learning theory (ELT), a model that emphasizes learning through experience, students from the construction management department are assigned four learning styles (converging, assimilating, diverging and accommodating). Performance data were gathered, appraised, and compared through the three dimensions from the Knowledge, Attitude and Practices (KAP) survey model across four categories of Kolb’s learning styles in both text-graph (TG)-based and AR-based learning settings.

The findings indicate that AR-based materials positively impact structural engineering education by enhancing overall learning performance more than TG-based materials. It is also found that the learning style has a profound influence on learning effectiveness, with AR technology markedly improving the information retrieval processes, particularly for converging and assimilating learners, then diverging learners, with a less significant impact on accommodating learners.

These results corroborate prior research analyzing learners' outcomes with hypermedia and informational learning systems. It was found that learners with an “abstract” approach (convergers and assimilators) outperform those with a “concrete” approach (divergers and accommodators). This research emphasizes the importance of considering learning styles before integrating technologies into civil engineering education, thereby assisting software developers and educational institutions in creating more effective teaching materials tailored to specific learning styles.

Contemporary literature reveals that, to date, the poultry livestock sector has not received sufficient research attention. This particular industry suffers from unstructured supply chain practices, lack of awareness of the implications of the sustainability concept and failure to recycle poultry wastes. The current research thus attempts to develop an integrated supply chain model in the context of poultry industry in Bangladesh. The study considers both sustainability and supply chain issues in order to incorporate them in the poultry supply chain. By placing the forward and reverse supply chains in a single framework, existing problems can be resolved to gain economic, social and environmental benefits, which will be more sustainable than the present practices.

The theoretical underpinning of this research is ‘sustainability’ and the ‘supply chain processes’ in order to examine possible improvements in the poultry production process along with waste management. The research adopts the positivist paradigm and ‘design science’ methods with the support of system dynamics (SD) and the case study methods. Initially, a mental model is developed followed by the causal loop diagram based on in-depth interviews, focus group discussions and observation techniques. The causal model helps to understand the linkages between the associated variables for each issue. Finally, the causal loop diagram is transformed into a stock and flow (quantitative) model, which is a prerequisite for SD-based simulation modelling. A decision support system (DSS) is then developed to analyse the complex decision-making process along the supply chains.

The findings reveal that integration of the supply chain can bring economic, social and environmental sustainability along with a structured production process. It is also observed that the poultry industry can apply the model outcomes in the real-life practices with minor adjustments. This present research has both theoretical and practical implications. The proposed model’s unique characteristics in mitigating the existing problems are supported by the sustainability and supply chain theories. As for practical implications, the poultry industry in Bangladesh can follow the proposed supply chain structure (as par the research model) and test various policies via simulation prior to its application. Positive outcomes of the simulation study may provide enough confidence to implement the desired changes within the industry and their supply chain networks.

The composition and subject balance of manuscripts in this Open Issue of OPEN HOUSE INTERNATIONAL range from experimental housing, through to mass customisation to Post-Disaster housing procurement methods and community oriented high rise building and Open Building. Starting with the Validity of PREVI, Lima, Peru, (p.6, Salas and Lucas, 2011) the focus is on an evaluation some forty years later after initial construction. Then on to Mass Customization of Housing, Malaysia, (p.16, 2011) for promoting customer satisfaction and contributing in the long run to sustainability of the housing industry. The overall conclusion was that there is a promosing future for customised housing coming directly from prospective buyers. In both cases large scale industrialised operations are the key words BUT rather than huge three dimensional elements, the proposals opted for precast small elements on an industrial basis deployed in a rationalised construction philosphy thus allowing users to participate in the design and building process.

This study aims to develop a system dynamics (SD) simulation model to forecast the performance of the Indonesian halal industry to verify whether decision-making has been properly executed to increase the contribution of the success factors.

This study establishes a SD-based model using three subsystems, namely, the halal assurance and certification process, the government and the export–import subsystem.

The best scenario is the third scenario or the combined scenario of providing facilities to accelerate the micro-, small- and medium-sized enterprises (MSMEs), carrying out halal certification, reducing the time for the certification process, increasing the number of the halal auditor and increasing the awareness from enterprises (both MSMEs and large enterprises) to carry out halal certification because of the internal and external motivations.

First, the demand for certification of the type of food product is acquired using the number of SMEs and large companies. Second, the model does not include the government budget as a constraint.

This study provides essential insights into implementing the best policies that can increase the performance of the halal industry.

This study revealed that relevant policy scenarios could be built after simulating and analyzing each scenario’s effect on the halal industry’s performance.

This study will enrich the scientific insight related to institutional theory and resource-based view, as those theories identify success factors associated with the performance of the halal food industry. This study will also enrich the scientific insight related to system dynamic methodology, as it is used to model the performance of the halal industry.

The purpose of this paper is to study the influence of centralization and formalization on the frequency of political tactics (FPT) used by employees. It also examines political will as the underlying variable that mediates the relationship between the focal variables.

The study uses data (n = 234) collected from a large public sector organization in India. The interrelationships are tested empirically using structural equation modeling.

The findings suggest that both centralization and formalization significantly influence the FPT used by employees. Also, political will partially mediate the relationship between centralization, formalization and FPT.

The study provides evidence of the influence of centralization and formalization as two organizational realities that lead to employee engagement in political tactics. It also elucidates the importance of political will and the need to develop social astuteness to maneuver through the maze of organizational politics. The study is conducted in a public sector organization in India and uses cross-sectional data. Therefore, generalizations must be made with caution.

The study establishes political will as an important mediator between centralization, formalization and political behavior, fostering in-depth research into the structural aspects of public sector organizations. It also establishes political will as an important individual disposition of employees that augments the engagement of employees in political behavior in highly centralized and formalized organizations.

The purpose of this paper is to study the correlational and effect relationship between Halal standards and the performance of Halal-certified Palestinian Food Companies.

Quantitative method was used, using a questionnaire survey of 40 Halal-certified Palestinian organizations out of a total of 47 certified organizations, the analysis was done using the partial least squares structural equation modeling (PLS-SEM) and the literature review was conducted using a well-known systematic literature review methodology.

Halal implementation and certification had a positive impact on performance (operational, financial and marketing). The depth/intensity of implementation fully mediates operational performance and partially mediates marketing and financial performance.

As the sample size is small, it is recommended to conduct the study using a larger sample size, once the number of Palestinian Halal-certified organizations increases. A longitudinal or panel study is recommended to capture data that are more accurate and avoid objectivity and bias issues using a cross-sectional research design method. Finally, the study recommends to conduct additional research in the field of Halal awareness for customers to gage their intention and welling to buy Halal products within the Middle East region.

The importance of this study exists in the lack of previous Halal-related studies in the Palestinian context and the previously described gap in the literature. Nevertheless, the quality management drivers and impact are limited in the Palestinian context compared with other contexts; the results of the previously published studies revealed mixed results such as the drivers of quality management are based on the type of business. Finally, this research gives small insights and directions toward conducting additional studies concerning customer awareness about Halal products.

With the impending development of green buildings in Kuala Lumpur, the capital city of Malaysia, managing the criteria within the requirements of the rating tool’s certification shall be the responsibility of the respective parties when these buildings are in operations. In tenanted buildings, a lease agreement spells out the responsibilities of the owner/landlord and the tenants. The paper aims to discuss these issues.

The main aim of this study is to gauge the implementation of green lease among office buildings in Kuala Lumpur. This is made through an initial review of the adoption of green building criteria as well as the determination of the drivers and barriers perceived by office building managers in implementing green lease.

A survey amongst the managers of top grade office buildings in Kuala Lumpur revealed that the majority practiced some of the green criteria outlined in the Green Building Index. It also revealed that the most significant green lease terms commonly acknowledged by the respondents were energy and water-saving consumption as well as recycled material usage.

Through the identification of the barriers to implement green lease, the most significant barriers identified were related to cost and financing. Having identified these obstacles, appropriate action can be taken to bring forward green lease awareness amongst the various stakeholders in the office building sector in ensuring the successful operation of green buildings.

Globally, the business organisations are experiencing a transformation due to the Fourth Industrial Revolution (4IR). The need for an effective 4IR leadership has placed new demands on organisations to develop and select leaders to effectively lead the organisations in the 4IR era. Hence, it becomes important to understand the attributes for an effective 4IR leadership. This study examines the relationships between leadership styles, leadership traits, leadership intelligence and effective 4IR leadership to empirically validate the effective 4IR leadership framework that was conceptualised. The hypothesised relationships from the framework were tested using a survey of 416 senior construction executives across the nine provinces of South Africa.

To achieve the study objectives, an online survey was sent to construction firms across the nine provinces of South Africa. “Construction”, for the purpose of this study comprised building and civil engineering firms listed on the construction industry development board (cidb) register of contractors in South Africa. The target group was the upper echelon executives, i.e. Chairman, CEOs, managing directors and chief operating officers, and the survey was directed to contact e-mail of the study samples. The professional service providers (architects, consultants and surveyors) were not part of the survey sample. The database of the organisational leaders was obtained from the cidb. The online survey was created on the 23rd of August 2019 and closed on the 23rd of April 2020, thereby making the duration of the survey eight months. The total number of respondents at the time of closure of the survey was four hundred and sixteen (416). Structural equation modeling (SEM) was used for the analysis of the results.

This study validates the effective 4IR leadership framework as proposed by Alade and Windapo (2019) by empirically examining relationships between leadership styles, leadership traits, leadership intelligence and effective 4IR leadership. The findings from this study have shown that effective 4IR leadership is positively associated with leadership styles, leadership traits and leadership intelligence. Hence, an effective 4IR leader must spread the knowledge and understanding of the 4IR opportunities and threats in the organisations. The leader must ensure that the executives in the construction organisation become change conversant and ensure that the employees acquire 4IR skills. Multiple leadership intelligence is essential to effective 4IR leadership. These multiple intelligence are the ability to adapt knowledge and skills to different situations, ability to handle interpersonal relationships judiciously, a high level of understanding, ability to process and analyse information and ability to utilise knowledge from many disciplinary boundaries.

This study is focused on construction business organisations in South Africa. As such, similar studies on 4IR leadership effectiveness can be carried out in other countries and across other organisations. Future studies should also consider using a case study approach specifically focused on organisations with high implementations of 4IR technologies. Interacting with the leaders of such organisations and their employees will give a broader perspective in understanding the reasons of their effectiveness.

The leadership of construction organisations must partner with the academia, industry players and team members in their efforts to implement 4IR in their organisations. Also, the existence of a positive association between leadership traits and effective 4IR leadership implies that to ensure a 4IR-driven work process in construction organisations, the leadership must embrace disruption and quickly respond to change. Further, it can be concluded from the findings of this study that appropriate leadership styles are required for effective 4IR leadership. The appropriate leadership style for effective 4IR leadership requires the leadership of construction organisations to delegate some of the 4IR function. The 4IR function must be performed based on the challenges that are associated with 4IR. The positive correlation between leadership intelligence and leadership styles makes it possible to conclude that the competencies of leadership of construction organisations in a 4IR-driven change depend on the level of leadership intelligence of the executives of construction organisations. It is evident that 4IR will change the business environment; hence, leadership intelligence is required to adapt construction organisations to the change dynamics. This study has provided information on what 4IR leadership entails in construction organisations. The study has contributed a framework for ensuring effective and smooth flow 4IR implementation in construction organisations through a purposeful leadership that combines leadership styles, leadership traits and leadership intelligence.

This research will be useful to government agencies and board members of construction organisations, in appointing leaders to see the construction industry and organisations perform better in the 4IR era. Young individuals who are also aspiring to take on leadership role in the industry will benefit from this study.

This study is a new and original research that seeks to investigate the need for an effective 4IR leadership in construction business organisations. Construction as an industry is usually criticised for her slow response to change. Since leadership is required to drive the change agenda, this study examines the relationships between leadership styles, leadership traits, leadership intelligence and effective 4IR leadership to empirically validate the effective 4IR leadership framework that was conceptualised.
