The purpose of this paper is to explain why the high quality cassava flour (HQCF) value chain in Nigeria has not performed as well as expected. The specific objectives are to: analyse important sources of uncertainty influencing HQCF value chains; explore stakeholders’ strategies to respond to uncertainty; and highlight the implications of different adaptation strategies for equity and the environment in the development of the value chain.

The authors used a conceptual framework based on complex adaptive systems to analyse the slow development of the value chain for HQCF in Nigeria, with a specific focus on how key stakeholders have adapted to uncertainty. The paper is based on information from secondary sources and grey literature. In particular, the authors have drawn heavily on project documents of the Cassava: Adding Value for Africa project (2008 to present), which is funded by the Bill & Melinda Gates Foundation, and on the authors’ experience with this project.

Policy changes; demand and supply of HQCF; availability and price of cassava roots; supply and cost of energy are major sources of uncertainty in the chain. Researchers and government have shaped the chain through technology development and policy initiatives. Farmers adapted by selling cassava to rival chains, while processors adapted by switching to rival cassava products, reducing energy costs and vertical integration. However, with uncertainties in HQCF supply, the milling industry has reserved the right to play. Vertical integration offers millers a potential solution to uncertainty in HQCF supply, but raises questions about social and environmental outcomes in the chain.

The use of the framework of complex adaptive systems helped to explain the development of the HQCF value chain in Nigeria. The authors identified sources of uncertainty that have been pivotal in restricting value chain development, including changes in policy environment, the demand for and supply of HQCF, the availability and price of cassava roots, and the availability and cost of energy for flour processing. Value chain actors have responded to these uncertainties in different ways. Analysing these responses in terms of adaptation provides useful insights into why the value chain for HQCF in Nigeria has been so slow to develop.

Recent developments suggest that the most effective strategy for the milling industry to reduce uncertainty in the HQCF value chain is through vertical integration, producing their own cassava roots and flour. This raises concerns about equity. Until now, it has been assumed that the development of the value chain for HQCF can combine both growth and equity objectives. The validity of this assumption now seems to be open to question. The extent to which these developments of HQCF value chains can combine economic growth, equity and environmental objectives, as set out in the sustainable development goals, is an open question.

The originality lies in the analysis of the development of HQCF value chains in Nigeria through the lens of complex adaptive systems, with a particular focus on uncertainty and adaptation. In order to explore adaptation, the authors employ Courtney et al.’s (1997) conceptualization of business strategy under conditions of uncertainty. They argue that organisations can assume three strategic postures in response to uncertainty and three types of actions to implement that strategy. This combination of frameworks provides a fresh means of understanding the importance of uncertainty and different actors’ strategies in the development of value chains in a developing country context.

This paper aims to provide an experiential exercise for management and leadership educators to use in the course of their teaching duties.

The approach of this classroom teaching method uses an experiential exercise to teach Adams’ equity theory and Vroom’s expectancy theory.

This experiential exercise has proven useful in teaching two major theories of motivation and is often cited as one of the more memorable classes students experience.

To the best of the authors’ knowledge, this is an original experiential exercise for teaching the equity and expectancy theories of motivation.

Stakeholder engagement in construction projects is an ingredient that contributes to project optimal performance. Many developing countries have a paucity of literature about stakeholders' engagement in construction projects. Therefore, the study investigated South Africa's shareholders' engagement in construction projects and recommended possible measures to mitigate potential limitations.

The researchers collated data from South African experts in stakeholder engagement via a phenomenology type of qualitative research design. They explored the “perceived hindrances” facing stakeholders' engagement in construction projects and proffer measures to mitigate them. The study analysed collected data via thematic analysis and achieved saturation. Three themes emerged from the analysed data.

Findings show that efficient stakeholder engagement will enhance team collaboration and integrated construction project delivery. Results identified the perceived limitations facing stakeholders' engagement in South Africa's construction projects and categorised them into individual perceived hindrances, organisational perceived hindrances and government-related perceived hindrances. Also, findings proffer measures to mitigate perceived hindrances via policies and programmes within the sector.

Besides enhancing policymakers and other stakeholders in South Africa's construction industry to understand the benefits of stakeholder engagement better, the study may stir up the construction sector's stakeholders to embrace enhanced and effective stakeholders' management.

This study contributes to construction project practice that involves stakeholders, as it reveals the underlying causes of perceived hindrances facing stakeholders' engagement in construction projects. Also, it proffers feasible solutions to mitigate these hindrances and enhance stakeholders' engagement within South Africa's construction projects.

Leaders emerge from some very unlikely situations. They come in all ages, sizes, shapes, and from both genders. In this paper we discuss the relationship between the theoretic and practical applications evidenced by the Institute for Community Leadership’s (ICL) efforts to prepare people for civic leadership. We present background information about ICL including the Institute’s purposes and goals, an examination of its past achievements, current activities, and future projections, and we conclude with a discussion of “conditions for success in collaborative public ventures” (Hackman & Johnson, 2009, p. 293) as it relates to the Institute’s efforts to prepare people for community leadership.

Building trust and living interpersonal trust are crucial corporate executive virtues that are needed today. Once you have developed and solidified a high level of genuine interpersonal trust with all your stakeholders, especially customers, suppliers, and employees, then you are on the right path of managing and transforming your company. A high level of interpersonal trust between all stakeholders and corporates in a business situation will break down communication barriers, foster serious conversation and sharing of ideas, and will eliminate corporate transactional anxieties of fear, mistrust, guilt, rigidity, blame, and resentment. When stakeholders trust you and you trust them, then you speak freely, they speak freely, and your mutual sustained transparency is a gateway to survival, revival, and sustained corporate recovery and transformation, and steady growth and prosperity. Conversely, when there is low trust, high mistrust, and high distrust among stakeholders in a business situation, communications and conversations are stressed and fragmented, teamwork and team spirit are very low, and the company is heading toward its ruin and extermination. Such is the crucial role of interpersonal trust in business. This chapter explores the crucial phenomenon of corporate interpersonal trust. We review various cases, models, concepts, definitions, and theories of trust from the management literature in general, and from the marketing field in particular, to derive psychological, behavioral, ethical, and moral principles of corporate trust, trusting relations, and trusting strategies.

This study examines the adoption drivers of scale-appropriate mechanization in Nepal's maize-based farming systems. The authors also assess the contribution of scale-appropriate mechanization to the United Nations Sustainable Development Goals (SDGs) of zero hunger (SDG2) and no poverty (SDG1).

Propensity score matching and doubly robust inverse probability-weighted regression adjusted methods were applied to estimate the effects of mini-tiller adoption. These methods control the biases that arise from observed heterogeneities between mini-tillers users and nonusers.

The study findings show that farm size, labor shortages, draft animal scarcity, market proximity, household assets and household heads' educational level influence the adoption of mechanization in Nepal. Mechanized farms exhibited enhanced maize productivity, profits and household food self-sufficiency. Reduced depth and severity of poverty were also observed. Nevertheless, these effects were not uniform; very small farms (≤0.41 ha) facing acute labor shortages benefited the most.

The study results suggest that policymakers in developing nations like Nepal may wish to expand their emphasis on scale-appropriate mechanization to improve farm productivity and household food security, reduce poverty and contribute to the SDGs.

This first-of-its-kind study establishes the causal effects between scale-appropriate farm mechanization and SDG1 (no poverty) and SDG2 (zero hunger) in a developing nation.

The purpose of this paper is to produce an intelligent technique for modelling machine tool errors caused by the thermal distortion of Computer Numerical Control (CNC) machine tools. A new metaheuristic method, the cuckoo search (CS) algorithm, based on the life of a bird family is proposed to optimize the GMC(1, N) coefficients. It is then used to predict thermal error on a small vertical milling centre based on selected sensors.

A Grey model with convolution integral GMC(1, N) is used to design a thermal prediction model. To enhance the accuracy of the proposed model, the generation coefficients of GMC(1, N) are optimized using a new metaheuristic method, called the CS algorithm.

The results demonstrate good agreement between the experimental and predicted thermal error. It can therefore be concluded that it is possible to optimize a Grey model using the CS algorithm, which can be used to predict the thermal error of a CNC machine tool.

An attempt has been made for the first time to apply CS algorithm for calibrating the GMC(1, N) model. The proposed CS-based Grey model has been validated and compared with particle swarm optimization (PSO) based Grey model. Simulations and comparison show that the CS algorithm outperforms PSO and can act as an alternative optmization algorithm for Grey models that can be used for thermal error compensation.

This paper reviewed backgrounds and necessary items for education and capacity buildings in Future Earth projects by implementing three main priorities in Future Earth and current surrounding environments.

This paper then suggested a possible structure, competencies, contents and human resources for education and capacity building and education for Future Earth.

The suggestions can be implemented in capacity building and education programs associated with Future Earth.

Nigeria has one of the highest graduate unemployment rates in Africa, and there is no comprehensive policy framework to address it. Evidence shows that integrating craftsmanship into higher education academic programmes can enhance graduate employability. Therefore, there is a need to integrate it into the built environment programmes at institutions in Nigeria. The built environment craftmanship (BEC) in Nigeria's HEIs may have had some challenges, although studies about these challenges are scarce. In this regard, the study investigated BEC's perceived encumbrances and proffered measures to integrate craftsmanship skills in Nigerian HEIs built environment programmes.

The research adopted a qualitative research design using a virtual interview approach to solicit data from 34 experts across Nigeria. An exploratory approach was used to engage selected HEIs in Nigeria and thematic analysis was adopted to analyse the collected data, and saturation was achieved.

The study findings indicate that integrating BEC in built environment programmes will enhance graduate employment. However, possible encumbrances like institutional frameworks, funding, infrastructural development and pedagogical and social-cultural issues were found to be affecting BEC's integration into built environment programmes at higher education in Nigeria.

Future studies should explore more detailed large-scale investigations about integrating craftsmanship into higher education institution (HEI) programmes.

Given the dearth of pragmatic studies on the built environment graduates' unemployment in Nigeria, this research contributes to the academic community debates on reducing graduates' unemployment via BEC in HEIs.

The purpose of this paper is to examine how police authority – in its “soft” form – is used and understood by staff and detainees in police custody in England, examining how these meanings are shaped by this unique police setting. It is argued that the nature of this setting, as fraught and uncertain, along with the large volume of citizens who come into contact with the police therein, makes police custody the ultimate “teachable moment”.

The present paper is based on in-depth qualitative data collected between March 2014 and May 2015 in four custody suites (in four forces). In each site, the researchers spent three to four weeks observing and then interviewed 10-15 staff (largely police officers, detention officers but also a few other criminal justice practitioners) and 10-15 detainees. In total, the paper is based on 532 hours of observing and 97 interviews (47 with staff and 50 with detainees).

One way that the staff used their authority in the custody suites in the research was softly and innocuously; this entailed for example staff communicating in a respectful manner with detainees, such as by being deliberately polite. The authors conclude that this “soft” power was a dynamic, processual matter, shaped in particular by the physical conditions of the suite, the uncertain and insecure nature of detainees’ circumstances, as well as by the sense of disempowerment they felt as a result of being deprived of their liberty and autonomy, all of which contributed to police custody being the ultimate “teachable moment”.

The paper draws on a range of qualitative data collected from both staff and detainees in four types of police custody suites as part the “good” police custody study. It therefore makes an original contribution to the field which has tended to rely on cross-sectional surveys of citizens not policed populations (Harkin, 2015; Worden and Mclean, 2017).
