Purpose: This paper examines the nexus between supply chain social capital (relational social capital and structural social capital), supply chain responsiveness (operations system responsiveness and supplier network responsiveness) and firm performance. Additionally, the study examines the mediating role of supply chain responsiveness on the relationship between supply chain social capital and firm performance. Design/methodology/approach: The authors test their hypotheses on a sample of 120 firms operating in Ghana. The measurement model and hypothesized paths were assessed using partial least squares structural equation modelling. Findings: The findings revealed that structural social capital had a significant direct effect on firm performance, but relational social capital did not. It was also revealed that both relational and structural social capital have significant effects on operations system responsiveness and supplier network responsiveness. Additionally, operations system responsiveness fully mediated the effect of relational social capital on firm performance and partially mediated the effect of structural social capital on firm performance. Supplier network responsiveness, on the other hand, partially mediated the effect of both relational and structural social capital on firm performance. Originality/value: This study contributes to the limited literature on supply chain social capital by unearthing the mechanisms through which supply chain social capital enhances firm performance. Specifically, the study demonstrates the intervening role of operations system responsiveness and supplier network responsiveness in the supply chain social capital–firm performance link.

Purpose: This paper aims to evaluate the risk factors and determines the overall risk level (ORL) of public-private-partnership (PPP) power projects in Ghana using fuzzy synthetic evaluation methodology (FSEM). Design/methodology/approach: In this paper review of literature led to the development of a 67-factor risk list which was ranked by experts and industry practitioners through a questionnaire survey. Findings: These factors were grouped into principal risk factors (PRFs) using component analysis and they served as the input variables for fuzzy analysis. The seven components were: Contract and Payment risks, Environmental risks, Financial and Cost risks, Legal and Guarantee risks, Operation risks, Socio-Political and Performance risks (SPR) and Tender and Negotiation risks. Study showed that the ORL of Ghanaian PPP power projects is high implying they are risky to both the public and private sectors. Fuzzy analysis also confirmed SPR as the most critical principal factor. Originality/value: This study is significant and demonstrates that fuzzy methodology can be used as a useful risk evaluation tool and risk assessment framework for private investors, policy makers and public sector.

Purpose: This paper explores stakeholder perceptions on the nature and extent of sustainability reporting on the websites of technical universities (TUs) in Ghana. Design/methodology/approach: The authors collected data from the websites of the 10 TUs in Ghana and interviewed the stakeholders of the TUs. In analyzing the data, the authors used thematic analysis for the interview responses. The authors also adopted the global reporting initiative (GRI) guidelines and campus sustainability assessment tools for the presentation and analysis of the sustainability disclosures on the websites of the TUs. Findings: The authors found that due to weak institutional coercions, there were limited disclosures on the websites of the TUs, which aimed at gaining stakeholders' legitimacy; the disclosures were more focused on organizational profile, governance and educational aspects of sustainability. To a large extent, while some external stakeholders such as parents, regulators and alumni appear to be less interested in the disclosures on the TU's websites, internal stakeholders such as employees (teaching and non-teaching staff) and students who frequently visited the TU's websites perceived limited reporting and were not impressed with the extent of sustainability disclosures on these websites. Practical implications: The findings of this study are intended to assist policy-makers in the educational sector to appreciate the importance of sustainability reporting on their websites. The results of this study will assist higher educational institutions (HEIs) in increasing the success rate of sustainability implementation by overcoming the lack of sustainability disclosures on their websites. Thus, the results of this study have implications for sustainability implementations, particularly those in emerging economies and policy-makers of universities worldwide. Originality/value: This study could provide two significant values. First, to the best of the authors' knowledge, no other study has explored stakeholder perceptions of sustainability reporting in implementing sustainability within the education sector. Second, the results were arrived at by combining stakeholder consultations with content analyses, which could be a good guideline for sustainability implementation in the educational sector of developing countries.

Purpose: This paper investigates the combined effect of internal environmental management (IEM) and green human resource management (GHRM) on corporate reputation (CR), environmental performance (EP) and financial performance (FP). The paper further explores the indirect effects of CR and EP between the direct paths. Design/methodology/approach: Data are garnered from 164 firms from three industries in Ghana. Partial least square structural equation modeling (PLS-SEM) is the methodological technique used to test the hypothesized relationships. Findings: The result demonstrates that unlike IEM which has a significant effect on FP when implemented in isolation, GHRM does not have a significant effect on FP. However, the joint implementation of IEM and GHRM can provide better results in terms of improved CR, enhanced EP and significant FP improvement. CR and EP were further found to mediate the relationship between the direct paths. Practical implications: The results suggest that the joint implementation of IEM and GHRM is critical for firms that seek to enjoy superior reputation, enhance their environmental sustainability and achieve financial gains. Consequently, managers are strongly encouraged to create a sustainable and vibrant company via significant and rational investment in green initiatives like IEM and GHRM. Originality/value: This study happens to be one of the first to develop a research model that investigates the joint effect of IEM and GHRM within the context of CR, environmental sustainability and FP.

Purpose: Based on the trait activation theory, the current study systematically integrates how autonomy interacts with proactivity to influence the relationship between ethical leadership style and employee creativity. Design/methodology/approach: Using simple random sampling and questionnaires, a sample of 475 engineering employees of 3 leading telecommunication companies in Ghana were obtained. The analysis was done using structured equation modeling (SEM), using SmartPLS. Findings: The results showed that ethical leadership style provides employees with job autonomy which facilitates individual creativity. Employee proactivity also moderates a positive relationship between autonomy and creativity such that high-proactive employees are well placed to produce more creative outcomes when given autonomy. At the individual level, personal characteristics determine the degree of creativity. Practical implications: The current study implies that telecommunication companies should put in more efforts to train and encourage leaders to be ethical in leaders' dealings with employees and employees must be rewarded for taking initiative. Originality/value: With a focus on the integrative approach from a developing economy, this work is novel in exploring how contextual and personal features impact creativity. [ABSTRACT FROM AUTHOR]

Purpose: The objective to achieve economic growth and sustainable development (SD) within the maritime industry has ever since been the ultimate goal of the International Maritime Organization and its stakeholders. Coupled with this effect, the United Nations organization has also mandated all its bodies to adopt sustainable working policies and practices towards the achievement of SD in its 2030 Agenda. From the standpoint of an emerging economy, this study aims to examine green maritime practices adopted by maritime authorities towards the achievement of SD in the maritime industry of Ghana. The proposed conceptual model of this study supports the natural resource-based view theory advocated by Hart (1995). Design/methodology/approach: The dataset of this study was gathered using semi-structured questionnaires. A total of 635 valid responses were received as feedback which were tested and analyzed using partial least square structural equation modelling. The rationale for the adoption of this analytical tool is its resilient ability to handle a relatively small quantity of datasets. It is also suitable for empirical studies involving model development and at the early stage of theory development. Findings: The findings of the study are as follows; firstly, quality maritime education and training directly and significantly influence green maritime transport (GMT), clean ocean and maritime resource conservation (COMRC), green port operations and services (GPOS), SD and waste management and treatment systems (WMTS). Secondly, GMT, COMRC, GPOS and WMTS have a direct significant influence on SD. Lastly, GMT, COMRC, GPOS and WMTS partially mediate the relationship between quality maritime education and training and SD. Practical implications: This study proposes a conceptual model that attempts to explain to maritime authorities and stakeholders that although the adoption of green maritime practices significantly influences SD, yet, it may be insufficient without quality maritime education and training provided to maritime professionals. Hence, emphasizing that all maritime personnel receive quality maritime education and training to enhance the long-term achievement of SD in the maritime industry. It also attempts to prove and suggest to maritime authorities how they can collectively integrate both onshore and offshore green maritime practices to achieve SD. Originality/value: The originality of this study shows in testing a conceptual model that affirms that, achieving SD in the maritime industry is dependent on quality maritime education and training received by maritime personnel, hence, demonstrating the significant role of maritime training institutions towards the maritime industry and the achievement of SD.

Purpose: Using the institutional and natural resource-based view theories, the purpose of this study is to examine the influence of religious, cultural and mimetic orientations on proactive environmental strategy, corporate environmental responsibility and traditional environmental strategy. Relying on data collected from managers of small and medium-sized enterprises (SMEs), the study further examines how proactive environmental strategy, corporate environmental responsibility and traditional environmental strategy drive relational capital and firm performance of SMEs operating in Ghana. Design/methodology/approach: The study employed a survey research design, a quantitative approach and a partial least square structural equation modelling technique in making data analysis and interpretations due to its appropriateness for predictive research models. Findings: The results suggest that mimetic orientation robustly and significantly influence the dimensions of environmental orientation. While religious orientation only had a robust and significant influence on proactive environmental strategy, cultural orientation robustly and significantly influences both proactive and traditional environmental strategies. Despite the positive and significant interactions that exist between proactive environmental strategy, corporate environmental responsibility, traditional environmental strategy, relational capital and firm performance, the findings particularly revealed that proactive and environmental strategies insignificantly correlated with relational capital contrary to past study findings. Originality/value: The study is among the few to examine how religious, cultural and mimetic orientations interrelate with proactive and traditional environmental orientations, relational capital and firm performance in an emerging economy. Based on the findings, implications and directions for future research are discussed while also providing guidance for policymakers, regulatory bodies, scholars and practitioners.
