The purpose of this study was to investigate the implications of green knowledge sharing (GKS), organizational green culture (OGC) and green training and development (GTD) for organizational environmental citizenship behavior (OECB) in the hotel sector in Ghana.

Using self-administered survey procedures, 415 operational-level employees in hotel facilities provided the data and was analyzed through partial least square structural equation modeling. Bootstrapping was conducted using 10,000 subsamples and Importance-Performance Map Analysis (IPMA) performed.

It was established that GKS influences both OECB and OGC. OGC also influenced OECB and played a mediating role in the influence of GKS on OECB. Similarly, GTD played a positive moderating role in the link GKS has on OECB. Finally, it was revealed via IPMA that OECB’s most important antecedent is GKS.

Due to the roles of GKS and GTD in promoting OGC and OECB, organizations should motivate their employees to share green knowledge and also invest more in GTD. Gamification and sponsoring employees to attend GTD programs are examples of actions to be taken in this regard.

This study explores antecedents of OECB which is overlooked in the literature in general and specifically, hospitality industry-focused green studies. Using IPMA, it also determines the most important antecedent of OECB which most studies focused on the hospitality industry do not go further to do.

The purpose of this study was to investigate the implications of green knowledge sharing, green empowerment and participation and green values toward hotel employees’ green creativity.

Data was gathered from operational level employees of hospitality facilities Ghana. Through the partial least square structural equation modeling, bias-corrected and accelerated (BCa) confidence intervals obtained from 10,000 bootstrap subsamples were used to determine the significance of the hypothesized paths. This was preceded by examining the quality of the measurement and structural models.

It was established that green knowledge sharing is a positive predictor of green empowerment and participation. Green empowerment and participation also positively predicted employee green behavior and also partially mediated the link between green knowledge sharing and employee green behavior. Green values also positively moderated the connection green knowledge sharing has with employee green behavior.

To enhance the green creativity of their employees so that the sustainability objectives are attained, general managers in hotels should institute strategies that promote green knowledge sharing among their employees, ensure the green empowerment and participation of their employees and inculcate green values in their employees.

This study expands the hotel greening literature by establishing the mediating and moderating processes for employee green creativity which is underrepresented in the literature. Besides, it extends the social learning theory in a green context.

The purpose of this study was to investigate the likely causes of failure of some sections of road pavements in Ajaokuta, Northcentral Nigeria. This was achieved through a geotechnical assessment of subgrade soils in affected areas.

The methods entailed field and laboratory methods and statistical analysis. Subgrade soil samples were retrieved from a depth of 1,000 mm beneath the failed portions using a hang auger. The soils were analyzed for natural moisture content (NMC), Atterberg limit (liquid limit, plastic limit and linear shrinkage), grain size distribution, compaction and California bearing ratio (CBR), respectively.

The results of the geotechnical tests ranged from NMC (12.5%–19.4%), sand (84%–98%), fines (2%–16%), LL (16.0%–32.2%), PL (17%–27.5%), LS (2.7%–6.4%), PI (2.5%–18.4%), maximum dry density (1756 kg/m2–1961 kg/m2), optimum moisture content (13.2%–20.2%), unsoaked CBR (15.5%–30.5%) and soaked CBR (8%–22%), respectively. Pearson’s correlation coefficient performed on the variables showed that some parameters exhibited a strong positive correlation with r2 > 0.5.

Funding was the main limitation.

Comparing the results with Nigerian standards for road construction, and the AASHTO classification scheme, the subgrade soils are competent and possess excellent to good properties. The soils also exhibited very low plasticity, a high percentage of sand, high CBR and low NMC, which implies that it has the strength required for road pavement subgrades. The likely causes of the failures are, therefore, due to the use of poor construction materials, technical incompetence and poor compaction of sub-base materials, respectively.
