This study aims to examine the relationship between green supply chain management (Green SCM) practices and environmental performance, and develop an integrated model to explain the mediating role of ecocentricity on the relationship between Green SCM practices and environmental performance in the context of the Ghanaian downstream petroleum industry.

To address the objectives of the study, a survey had been conducted among companies in the Ghanaian downstream value chain. The paper used the structural equation modeling approach and smart partial least squares (Smart-PLS) analytical tool.

The study revealed that Green SCM practices had a significant and positive relationship with supply chain ecocentricity and environmental performance. The study further revealed that supply chain ecocentricity significantly mediated the relationship between Green SCM practices and environmental performance.

The study has developed a new integrated model to enhance oil and gas marketing and distribution company's adaptation and implementation of Green SCM practices.

The study had successfully applied the natural resource-based view and the stakeholder theory in the context of Ghana's downstream petroleum industry. Specifically, these theories had been integrated to form a new model to explain the relationship between Green SCM practices, supply chain ecocentricity and environmental performance in the context of Ghana's downstream petroleum industry. The newly developed integrated model has wider predictability as compared to the individual theories.

Thus, this study aims to determine the status-quo of research on the role of IT in M&A from 2010 to 2022 by providing a summative meta-analysis of this phenomenon.

This study presents a meta-analysis of mergers and acquisitions (M&A) research in information systems (IS), aimed at accounting for themes in M&A literature over the past 13 years, research methodology, research frameworks, level of analysis and geographical distribution. A total of 47 articles from 24 peer review articles and 23 conference publications were analyzed from 2010 to 2022.

Findings of the study suggest that M&A research in IS emphasizes IS integration at the expense of other under-explored dimensions such as M&A context, stakeholder involvement and within-firm conditions. Although studies on M&A have increased over the past 10 years, a significant number of studies have not been underpinned by models and theories. Also, a large number of studies adopted the qualitative approach as research methodology compared to quantitative, design science and mixed methods.

This study contributes to the literature on M&A in IS by proposing an M&A in IS research framework that bridges the gap between existing and future studies on M&A in IS research by shedding more light into well research areas and opportunities for further studies.

The purpose of the study is to assess the nutritional and health status of people living with HIV/AIDS (18-60 years) in selected health facilities in the eastern region of Ghana and to determine the influence nutrition support programmes (NSP) have on the nutritional and health status of people living with HIV/AIDS.

A retrospective study design was used. Purposive and convenience sampling was used to select four hospitals and 200 beneficiaries and non-beneficiaries of the NSP. A structured questionnaire was used to collect the sociodemographic, anthropometric, biochemical and clinical history of the participants. Dietary intake was assessed with food frequency and 24-h dietary intake questionnaires. Previous data from the medical record within three to six months before the research was collected and compared with current data.

The prevalence of underweight (using body mass index) was 17 per cent and overweight/obesity was 37 per cent. Most respondents had adequate consumption of phosphorus (70.5 per cent); inadequate intake of calcium (95 per cent), vitamin E (77.5 per cent) and vitamin A (94 per cent); and excess intakes of sodium (93 per cent), selenium (77 per cent), copper (83.5 per cent) and manganese (76 per cent). There was no significant difference in nutrient intake of beneficiaries and non-beneficiaries of the NSP, although there were significant differences in the frequency of consumption of fruits (p < 0.001), vegetables (p < 0.001), legumes (p = 0.002), animal foods (p < 0.001) and cereals, grains and starch (p < 0.001) between beneficiaries and non-beneficiaries of NSP. About 38 and 20 per cent of respondents, respectively, had low haemoglobin (Hb < 11 g/dL) and high viral load (1,000 cp/mL). Comparing the current and previous (three to six months before the study) health and nutritional status of beneficiaries and non-beneficiaries of NSP, among the beneficiaries of NSP, monocytes increased by 40.6 per cent (p = 0.028) and mean weight decreased by 2.4 per cent (p = 0.007), Hb decreased by 7.1 per cent (p = 0.27) and viral load decreased by 4.2 per cent (p = 0.49), whereas among the non-beneficiaries, mean weight decreased by 0.05 per cent (p = 0.95) and Hb increased by 9.6 per cent (p = 0.06) and monocytes increased (p = 0.28) and viral load increased by 98.2 per cent (p = 0.34).

A significant proportion of people living with HIV/AIDS had a high prevalence of underweight and overweight/obesity, inadequate nutrients intake and high viral load. The NSP for people living with HIV/AIDS in the eastern region of Ghana did not significantly influence the nutritional and health status of these people.

Knowing the nutritional status will help health institutions plan activities towards improving the health and nutritional status of people living with HIV/AIDS. This research is aimed at not only contributing to the existing body of knowledge but also making recommendations of action towards improving NSPs of people living with HIV/AIDS.

Improvement in nutritional and health status of people living with HIV/AIDS will help reduce morbidity and mortality and its related cost to families, communities and the nation.

This study is first to determine the influence of NSPs on nutritional and health status of people living with HIV/AIDS in the eastern region of Ghana.
