“…Other tools such as Relative Important Index (RII) and the One-sample t-test were also used. According to Rooshdi et al (2018), RII allows the identification of the most important criteria based on the responses of the participants of the survey and it is also an appropriate tool to prioritise the indicators rated on the Likert scale adopted for the study. The RII was calculated using the formula below: [W -weighting given to each statement by the respondents ranging from 1 to 5; Ahigher response integer ( The Cronbach's Alpha Coefficient test was used to ascertain the reliability and internal consistency of the scale adopted for the study.…”

Purpose The advances in green city growth are widely discussed in extant literature. The benefits of green cities to urban development in recent discussions of sustainability and sustainable development are well documented and cannot be overemphasised. Although a growing study on green building development in developing countries has been advanced in literature, there is a paucity of studies that explore green cities in developing countries. Moreover, evidence of studies that have focussed on green cities development in Ghana is lacking. Because of this identified knowledge gap, the purpose of this study is to establish the indicators/attributes for measuring the level of greenness of cities in developing countries. Design/methodology/approach A comprehensive literature review was conducted to identify the indicators/attributes for measuring the level of greenness of cities in developing countries. This study has adopted the pragmatism as its undergirding research philosophy and the deductive research approach. In terms of methodological choice, quantitative research strategy was used to collect data from experts in sustainable urban development. The primary data retrieved from this study was analysed using descriptive statistics, relative importance index and one-sample t-test. The reliability and validity of this study were measured with the Cronbach’s alpha test. Findings This study established eight indicators for measuring green city development: air quality, water, sanitation, land use, health and safety, transportation, energy and building and construction. It was discovered that the development of green cities should enhance air quality, improve water production and supply, improve management in sanitation, promote mixed and integrative land use, maintain the health and safety of city dwellers, reduce the demand for transportation and formalise public transport, adopt renewable and efficient energy technologies and promote sustainable construction and green buildings. These indicators are key to policymaking and implementation of green cities development. Research limitations/implications This study focusses primarily on Ghana; however, the findings of this study do not limit the generalisability, as it can be used as an example for other developing countries. Practical implications Theoretically, this study adopted quantitative indicators that are reproducible in another geographical context. This study contributively adds to the discourse on sustainability, especially in Ghana, and can be a source of reference to motivate others to conduct further research in related areas. The outcomes of this study will help the local government, policymakers, city stakeholders and industry expertise to gain insights of the overall indicators that underpin green city development. Originality/value This paper attempts to posit in literature the foremost appraisal of green city indicators adaptive in Ghana, which could motivate other developing countries to develop their own green cities.

“…The long-term impacts of green construction offer formidable solutions to promoting sustainability for future generations [64]. The evidence in the study indicates that there is a difference in the quality of highway engineering projects based on the costs incurred promoting green construction.…”

The implementation of green projects continues to encounter several challenges with regards to the project management techniques applied in different construction projects. This study aims to find out the relationship between green construction management and the quality of highway engineering projects, and to try to help innovators identify the best place to focus. This study adopted mixed research method where both quantitative and qualitative research approaches were used. The analysis techniques adopted included Pearson’s correlation, regression analysis, and Student’s t-test. The study found that the effect of financial issues, design codes and standards, and various risks will be the most effective green performance constructing strategies. It is revealed that there are eight determinants explained 77.5% of the variations in the quality of the highway engineering projects. The quality of highway engineering projects was expected to improve by 0.246 units for a unit change in the adoption of the green construction management. The research result will help stakeholders in improving the quality standards for highway engineering projects and help practitioners and experts in the construction project industry to better understand the relationship between green construction management and quality of highway engineering projects, and help them improve green construction management in an effort to promote sustainable development of project management. This research can be further studied in the future to expand the scope of data analysis to explain the differences in the level of social development.

“…where W is the weighting given by each participant on a 5-point Likert scale, in which 1 indicates low motivation and 5 indicates higher motivation; A is the highest weight, which was 5; N is the total number of participants. RII ranges between 0 and 1, where values between (0.8 ≤ RII ≤ 1) are high, (0.6 ≤ RII ≤ 0.8) are high-medium, (0.4 ≤ RII ≤ 0.6) are medium, (0.2 ≤ RII ≤ 0.4) are medium-low, and (0 ≤ RII ≤ 0.2) are low [36].…”

An Investigation of Healthcare Professionals’ Motivation in Public and Mission Hospitals in Meru County, Kenya

Strengthening health systems in developing countries such as Kenya is required to achieve the third United Nations’ Sustainable Development Goal of health for all, at all ages. However, Kenya is experiencing a “brain drain” and a critical shortage of healthcare professionals. There is a need to identify the factors that motivate healthcare workers to work in the health sector in rural and marginalized areas. This cross-sectional study aims to investigate the factors associated with the level and types of motivation among healthcare professionals in public and mission hospitals in Meru county, Kenya. Data were collected from 24 public and mission hospitals using a self-administered structured questionnaire. A total of 553 healthcare professionals participated in this study; 78.48% from public hospitals and 21.52% from mission hospitals. Hospital ownership was statistically nonsignificant in healthcare professionals’ overall motivation (p > 0.05). The results showed that sociodemographic and work-environment factors explained 29.95% of the variation in overall motivation scores among participants. Findings indicate there are more similarities than disparities among healthcare professionals’ motivation factors, regardless of hospital ownership; therefore, motivation strategies should be developed and applied in both public and private not-for-profit hospitals to ensure an effective healthcare workforce and strengthen healthcare systems in Kenya.
