Abstract
Purpose
The purpose of this paper is to investigate the use of Pinus wood waste in lead adsorption as a remediation technique in aqueous medium and its subsequent use in obtaining synthesis gas.
Design/methodology/approach
The capacity of the timber in the lead adsorption was studied in aqueous medium at various pH, determining the amount adsorbed in equilibrium. Then, the same timber was added in a fixed bed, co-current flow of two stage gasifier type, working temperature of 900°C, for obtaining synthesis gas. The synthesis gas composition was evaluated by the spectrophotometry in the infrared region and the gas chromatography and lead content in the ash and gas was determined by the atomic absorption spectrophotometry.
Findings
In laboratory tests carried out, the optimal pH for lead removal was pH 4 with 96.15 percent removal rate, reaching equilibrium after 180 min. In pilot scale the lead removal after 72 hours was 96 percent. The average production of syngas was 11.09 m³h−1. For tests with the motor-generator, the best condition occurred with charge of 2.0 kW, wherein gas consumption per kW produced reached 4.86 m³ kW−1, resulting in a 14.81 percent efficiency rate. The gas analysis showed an average concentration of 14.85 percent H2, 30.1 percent CO2, and 50.49 percent of atmospheric air. The concentration of lead in the gas was below the limit established by law. Pinus elliottii waste proved to be an excellent adsorbent, with removing more than 96 percent of the Pb ion present in aqueous solution and a starting material in the gasifier to generate synthesis gas.
Research limitations/implications
This paper describes the waste wood application in the treatment of contaminated environments and for obtaining syngas providing a sustainable process.
Originality/value
This paper shows a process that combines the remediation of contaminated environmental with power generation systems, allowing efficient management of contaminated environments.

Abstract
Purpose
The purpose of this paper is to study whether the effectiveness of innovation in improving a firm's performance varies in different competitive situations and to analyze whether the competitive forces act as a motivator or as an inhibitor.
Design/methodology/approach
The paper formulates some hypotheses from the literature review. These hypotheses are tested using structural equation modelling with data collected from 218 manufacturers.
Findings
The findings show that small firms must invest in innovation preferably when competitive forces are more intense. Moreover it is found the positive role that market orientation plays in promoting innovation and performance, no matter the level of the competitive forces.
Research limitations/implications
A decision had to be taken on the range of concepts and the domain used for measuring each concept. For future research the paper suggests considering different types of innovations (e.g. incremental vs radical) to get a more precise explanation of the set of relationships considered in this research.
Practical implications
SMEs have to use product innovation in accordance with their competitive situation. When competitive pressure is low, SMEs should be cautious about exaggerating investments on product innovation, whereas investments in other type of market oriented behaviours could be more productive. On the other hand, firms should focus on innovations based on market orientation when the competitive forces expose them to a harsh environment.
Originality/value
This paper provides a clarification of the reasons that may be behind a positive, a negative, or a non‐significant moderating effect of the firm's competitive forces on the market orientation‐product innovation relationship in small manufacturers.

Abstract
Purpose
This paper aims to demonstrate that aspects of a rational or functional character and aspects of an emotional and social nature condition the perceived value of the exchange relationships among firms in an industrial cluster.
Design/methodology/approach:
The research uses structural equation models (SEM) to test the models and applies the maximum likelihood estimation method in all the causal models obtained in the course of the data analysis.
Findings
The results obtained support the hypotheses put forward, and in particular the importance of emotional and social values in industrial relations.
Research limitations/implications
Recent advances in consumer and services marketing consider that perceived value and satisfaction are central to explaining customer loyalty. However, very few studies in B2B explain the multidimensionality of perceived value. For this purpose, the authors test their working hypotheses in the Spanish ceramic tiles cluster. Specifically, they analyze the relationships between manufacturers and a supplier of frits, enamels and ceramic colors and related services.
Practical implications
An empirical study demonstrates that experience and interpersonal relationships are more important than price and switching costs in an industrial cluster context. The empirical study and the results provide evidence for managers: the critical influence of the emotional and social values perceived by the customer on his level of satisfaction and on the achievement of final loyalty.
Originality/value
The paper highlights the importance of the most intangible dimensions of value for the relations between companies in an industrial cluster.

Abstract
Purpose
This paper aims at discussing the impact of quality electricity on household income (HI) in rural areas with complementarities and intermediary resources context.
Design/methodology/approach
Partial least square-structural equation modelling (PLS-SEM) was used to estimate complex variables of quality electricity (QEC), development assets (DEA) and individual motivation (IMO) on rural HI. Age, education and gender were treated as moderators of antecedents for HI whilst household strength (HS) was treated as a mediator.
Findings
The findings show that QEC is an important predictor for HI in rural areas. In similar vein, land, social network, financial and physical resources cannot be undermined in bringing HI on stage. Moreover, IMO is a best complementary for electricity to bear impact on income. In fact, income cannot be equated with one factor; hence, moderating roles of education and gender should be considered.
Research limitations/implications
The results are limited to QEC, IMO and DEA as key resources which are associated with HI.
Practical implications
The findings should be twinned with rural development policy. There must be a multi-dimensional approach in diversifying development resources to the rural people for aggregated benefits.
Social implications
The rural communities remain in dire need of electricity which is a precious resource for income generation. Electricity works better with other resources.
Originality/value
Previous scholars have inferred HI in relation to electricity. Income is a function of many resources. This study inculcated complementaries and intermediaries along QEC. Unique PLS-SEM was used in rethinking some of the rethinking of QEC–income relationships.

The purpose of this study is to investigate the range of explanations for why wine club members defect and move on.
Abstract
Purpose
The purpose of this study is to investigate the range of explanations for why wine club members defect and move on.
Design/methodology/approach
This quantitative research study uses data from US wine consumers, gathered through an online survey of 399 former wine club members who had quit their membership in the recent past. Consistent with literature on customer churn rates in subscription markets, data are analyzed using descriptive statistics, factor analysis, hierarchical multiple regression and analysis of variance.
Findings
The results reported by respondents indicate that higher levels of perceived product quality, fair value in pricing, variety seeking and commitment to customer service at the beginning and at the end of a wine club membership lead to higher levels of customer satisfaction and a desire to recommend the club to others even after quitting. Though variety seeking is more commonplace among experienced wine drinkers, the good news for wineries is that consumers are more likely to recommend a wine club to others if at least a year has passed after they decided to quit.
Practical implications
The results provide implications for wine club managers seeking to improve wine club retention with suggested means for mitigating the rate of customer attrition.
Originality/value
This paper presents original research addressing a variety of reasons why wine club members quit. The extant research has found that factors such as product quality, fair pricing, service commitments and variety-seeking behavior affect members’ satisfaction with their wine club, as well as their desire to recommend it to others. The authors have attempted to combine all these factors into a single study to gain insight into wine club members’ switching behavior, and to find out what the wineries can do to improve customer loyalty.

Abstract
Purpose
The purpose of this paper is to investigate a benchmarking project carried out by the Dubai Electricity and Water Authority (DEWA) as part of a structured benchmarking initiative. The project was based on the TRADE benchmarking methodology and this paper examines the tools, activities and outcomes that relate to each stage of the adopted methodology.
Design/methodology/approach
This study is based on case study methodology. Data were collected from various sources including analysis of project reports written by DEWA’s benchmarking team reporting on their activities during the project. Data were also collected from four project presentations given at different stages of the project. In addition, the research team held three meetings with the DEWA benchmarking team at different stages of the benchmarking project.
Findings
The results show the key challenges and successes faced during each stage of the benchmarking project. It indicates the actions taken to overcome the challenges and the role played by internal and external stakeholders in facilitating the success of the benchmarking project.
Practical implications
The study presents information that would guide organisations that wish to carry out a benchmarking project – and particularly those implementing benchmarking for the first time. The study provides a summary of the key lessons learnt by DEWA’s benchmarking team as a guide for other organisations.
Originality/value
Academic research has not adequately examined and analysed the stage-by-stage elements of a benchmarking project from the perspective of the implementing organisation. This study addresses this gap by detailing and analysing the experiences of a benchmarking project by tracking the stage-by-stage activities of the benchmarking team.

Abstract
Purpose
In light of the recent changes in the internal audit (IA) landscape, the role of auditors has undergone a significant transformation. This paper aims to investigate the effects of applying Lean Six Sigma (LSS) techniques on the effectiveness and efficiency of IA.
Design/methodology/approach
The study used a quantitative approach, surveying Iranian internal auditors with a sample size of 384 participants. Data analysis involved confirmatory factor analysis and structural equation modeling.
Findings
The analyses demonstrate a significant association between LSS application and IA effectiveness and efficiency. In addition, an exploratory analysis indicates that the application of LSS techniques by less experienced internal auditors had a reverse effect on IA function quality as a component of IA competency. However, IA motivation factors, including education and position, did not mediate the impact of LSS on IA effectiveness and efficiency.
Research limitations/implications
This study was conducted with Iranian internal auditors, which may limit the generalizability of the findings to other countries. However, the primary academic implication of this research lies in its novel perspective on emphasizing the concept of continuous improvement in IA through the use of LSS techniques. By focusing on the need for internal auditors to add value to the business in new ways, this research contributes to the literature on IA quality.
Practical implications
This study has significant implications for the effective management of IA departments. By promoting the application of LSS techniques in IA, lean auditing is enhanced, and IA can create value by improving the quality of its functions. Moreover, IA regulators can benefit from this study as it emphasizes providing guidance and training on LSS techniques to enhance IA skills.
Originality/value
This research is pioneering in applying LSS methodology to enhance the effectiveness and efficiency of internal auditing. It also considers the integration of lean thinking into current audit practices, making it unique and valuable in internal auditing research.

Abstract
Purpose
Literature on “gender and organisation” in developing countries is scarce. The purpose of this paper is to unveil the way in which gender construction is understood and operates within public organisational settings in the Dominican Republic.
Design/methodology/approach
Semi‐structured interviews were conducted with 27 women and 13 men from three organisations in the public sector in the Dominican Republic. The research was developed using a feminist poststructuralist methodological framework and used discourse analysis.
Findings
Gender construction and dynamics in the Dominican public sector reproduce paternalistic assumptions and beliefs. Organisational culture operates as a gendered system where sexualised structures and processes perpetuate ideas about male superiority and female inferiority, which translate in expectations of men being dominant and women being submissive.
Research limitations/implications
The experience of a group of employees from three public institutions cannot generalise the whole of the public sector all around the country. More importantly, it cannot be assumed to represent all feminist voices from developing countries.
Practical implications
The implications of this research are significant both for gender sensitive employment public policy reform and human resource management practices in the public sector.
Originality/value
The research focused on how gender is articulated in organisational culture, situating this problematisation in the public sector in the Dominican Republic. The paper contributes to the limited knowledge of gender and organisation in the Hispanic Caribbean, particularly the Dominican Republic.

This paper seeks to systematically review and synthesise existing research knowledge on African women entrepreneurship to identify gaps for future studies.
Abstract
Purpose
This paper seeks to systematically review and synthesise existing research knowledge on African women entrepreneurship to identify gaps for future studies.
Design/methodology/approach
The paper conducted a systematic literature review of published studies from 1990 to 2020 on women entrepreneurship in Africa using a 5M gender aware framework of Brush et al. (2009).
Findings
The systematic literature review of published studies found the fragmentation, descriptive and prescriptive orientation of studies on Africa women entrepreneurship and devoid of theoretical focus. Further, women entrepreneurship studies tended to be underpinned from various disciplines, less from the entrepreneurship lens, mostly quantitative, and at its infancy stage of development. With a primary focus on development, enterprise performance and livelihood, studies rarely attended to issues of motherhood and the nuanced understanding of women entrepreneurship’s embeddedness in family and institutional contexts of Africa.
Research limitations/implications
The paper questions the view that women entrepreneurship is a “panacea” and unravels how family context, customary practices, poverty and, rural-urban and formal/informal divide, significantly shape and interact with African women entrepreneurs’ enterprising experience and firm performance.
Practical implications
The findings and analyses indicate that any initiatives to support women empowerment via entrepreneurship should consider the socially constructed nature of women entrepreneurship and the subtle interplay of the African institutional contexts’ intricacies, spatial and locational differences which significantly influence women entrepreneurs’ choices, motivations and goals for enterprising.
Originality/value
The paper contributes to a holistic understanding of women entrepreneurship in Africa by using a 5M framework to review the research knowledge. In addition, the paper not only identifies unexplored/or less examined issues but also questions the taken-for-granted assumptions of existing knowledge and suggest adoption of context- and gender-sensitive theories and methods.
