Purpose The purpose of this paper is to assess the relationship between five green practices and firm performance. In addition, this paper investigates the influence of each green practice on environmental performance, economic benefits, and economic costs. Design/methodology/approach Data were collected based on a cross-sectional survey of owner/managers of 200 manufacturing SME firms in Uganda, Africa. SPSS was used to find descriptive means and test relationships between green practices and performance outcomes. Structural equation modelling was used to test for the influence of each practice on performance outcomes. The structural equation modelling results were obtained using the Covariance-Based Structural Equation Modelling software. Results were compared with similar studies conducted in developing countries. Findings Different green practices affect different performance dimensions in different ways across different industries. For example, eco-design and internal environmental management practices significantly influence environmental performance; green purchasing and internal environmental management practices significantly influence economic benefits; and internal environmental management practices affect economic costs. Overall internal environmental management is the key to positive outcomes across the three performance criteria. The authors show how the results obtained vary from similar studies conducted in developing countries and explain possible reasons for the difference. Research limitations/implications Africa is a rapidly industrialising nation faced with difficult choices between economic growth and increased pollution. Because SMEs represent the majority of manufacturing firms, they are the main polluters. Hence, better understanding of the costs and benefits, both environmental and economic, is important to encourage green practice adoption for the betterment of community health and prosperity. Originality/value Despite numerous studies on the relationships between green practice adoption and performance outcomes, only a few studies include both economic costs and benefits in addition to environmental performance. The study covers five green supply chain practices, whereas most similar studies are limited in the number of practices examined. The African context is unique and important because industrial development and environmental protection goals are in conflict. Similar studies are predominant in an Asian context which is more developed than Africa. The findings and comparisons raise important questions for further research in relation to the roles of national regulations, geographical markets and industry types in furthering green practices in manufacturing.

Purpose – The purpose of this paper is to advance enviropreneurial orientation (EO) as a new internal driver for green supply chain practice adoption. Because manufacturing supply chains are major contributors to environmental pollution, green practice adoption is a means of reducing environmental pollution. However, why owner/managers adopt green practices remains uncertain. The concept of EO is a potential and important motivation for adoption of green supply chain practices that has yet to be explored. The study investigates the relationship between EO and green supply chain practice adoption. Design/methodology/approach – Cross-sectional survey design was employed to collect data from owners/managers of SME manufacturing firms in Uganda. The structural equation modelling was used to analyse results on the influence of each of nine EO on green supply chain practice adoption and the influence of EO dimensions on green supply chain practice adoption. Findings – Findings show that EO positively influences green supply chain practice adoption. All but two of nine dimensions of EO were significant predictors of green supply chain practice adoption. Competitive aggressiveness and perceived pressure from environmental regulations were not significant predictors for green supply chain practice adoption. Research limitations/implications – The study was cross-sectional. A longitudinal survey was more appropriate because of the presence of a behavioural variable green supply chain practice adoption. Further a comparative study is required because of the existence of differences in classifications of SMEs in both the developing and developed countries. Originality/value – The research contributes to further scholarly understanding of green practice adoption in SMEs through offering a new construct, EO, and its role in influencing green supply chain practice adoption. The authors develop EO as a construct, a concept that has not been developed for more than two decades.

In Uganda, small and medium enterprises (SMEs) form the majority of firms in the private sector (90% of the firms in the private sector are SMEs). Their importance in Uganda's economy cannot be under looked because of the contribution that they make to national and economic development. The SMEs employ a high percentage of the non -farming population and contribute 70% of the total GDP (BID Country Guide Series, 2008: Hatega, 2007. SMEs in Uganda however face numerous challenges which affect their performance and survival in the long run. In their study on improving information access to SMEs in Northern Uganda, Okello -Obura (2008) established that SMEs have structural and operational challenges that need to be addressed imme-diately if economic development is to be attained because they are the engine of growth, employment creation and socioeconomic transformation. Hindrances that affect the performance of SMEs, their competitiveness and survival include limited information on financing options, inadequate and expensive supply of utilities and limited access to networks that are needed to enhance competitiveness (Hatega, 2007;Kigozi, 2006). SMEs also suffer delivery of poor quality products, late deliveries or no deliveries at all in their supply chains Ntayi, Rooks, Eyaa and Zeija, 2010). These aspects are indicators of poor performance of SME supply chains. Given that SMEs are very important in Uganda's economy, it is vital that the performance of their supply chains is addressed. Therefore, it is therefore important to gain

Purpose The purpose of this paper is to propose a new model that is inclusive and practical because of the deficiencies in models for construct measurement. Further, the authors demonstrate the value of the proposed model by describing its application to the development and validation of a multi-dimensional construct, enviropreneurial orientation. Although used in the literature, enviropreneurial orientation had not been developed nor tested as a construct. The paper provides detailed explanation of development and validation processes exemplified by experiences of research into the factors that motivate individual enviropreneurial orientation among owner/managers in supply chains. Design/methodology/approach The authors review models of construct development and propose an eight step model to overcome the deficiencies in the existing models. The eight steps are: defining the construct; identifying its dimensions; generating measurement items for each dimension; pretesting the measurement items; collecting data; constructing scales; analysing reliability; and evaluating the relationships. Each step is explained through examples based on the authors’ experience in using the model to develop the new construct – enviropreneurial orientation. Findings All correlation results were positive and significant as were the multiple regression results with one exception, competitive aggressiveness. Originality/value The authors provide a practical model to guide new construct measurement development which can be used by researchers and research students for multi-dimensional constructs, especially they are constrained by time and financial resources. By using an example to demonstrate the applicability of the model, the authors go beyond the usual description of construct development models to make the proposed model more comprehensible and thus useful.

PurposeThe study examined the influence of relational capital on inter-cluster coordination and service delivery of humanitarian organisations; the mediating and moderating role of inter-cluster coordination on the relationship between relational capital and service delivery.Design/methodology/approachData was collected from 60 humanitarian organisations. Potential respondents were five officers from each humanitarian organisation involved in delivering humanitarian assistance. Respondents from the different organisations were selected using purposive sampling. The SPSS software, SMART PLS and CB-SEM software were used to obtain results on the influence of relational capital on inter-cluster coordination and service delivery in humanitarian organisations; and the mediating and moderating role of inter-cluster coordination on the relationship between relational capital and service delivery.FindingsFindings indicated that relational capital influences inter-cluster coordination and service delivery in humanitarian relief chains; inter-cluster coordination partially mediates the relationship between relational capital and service delivery in humanitarian relief chains; and no interactive effect was found when the moderation effect of inter-cluster coordination on the relationship between relational capital and service delivery in humanitarian organisations was examined.Research limitations/implicationsThe study was mainly focused on humanitarian organisations excluding beneficiaries and the logistics suppliers. The research has implications to decision-makers in government and humanitarian organisations concerned with providing relief aid to beneficiaries.Originality/valueThe influence of relational capital on inter-cluster coordination and service delivery in humanitarian relief chains; the mediating role and moderating role of inter-cluster coordination on the relationship between relational capital and service in humanitarian relief chains are aspects that have not been given significant attention empirically.
