Abstract
Purpose
This study aims to identify the location of the micropyle, the role of the micropyle in seed germination and the association between the micropyle size and seed weight of grass peas.
Design/methodology/approach
First, the micropyle was identified by cutting the seed in half and observing the seeds under the electron microscope. Second, the micropyle was covered by lanolin to block water imbibition. The rate of imbibition and germination was then observed. Lastly, micropyle sizes of various grass pea genotypes were identified by capturing seed images under a light microscope and converting the sizes to mm2 using computer software (ImageJ).
Findings
The location of micropyle was located nearby the hilum, similar to soybean seeds. Seed imbibition was significantly lower in lanolin application (<87%) than in the control (>124%) after 24 hours of submergence. Germination was a day delay for lanolin application on the micropyle compared to lanolin application on the non-micropyle. The germination delay resulted in a significantly lower germination percentage at <57% on the micropyle lanolin application than at >79% on the non-micropyle lanolin application after 10 days of sowing. There is no correlation between the micropyle size and seed weight.
Originality/value
These findings add information on the location and the role of the micropyle for grass pea seed germination.

Abstract
Purpose
This paper aims to investigate whether relational agency fosters relational people management using evidence from micro and small enterprises in Uganda, an African developing country. Specifically, the paper examines whether the individual relational agency dimensions (shared learning, mutual cooperation, collective efficacy and interaction enablement) also affect relational people management.
Design/methodology/approach
A cross-sectional survey design using a quantitative approach was used in this study. Data were collected from 241 micro and small enterprises in Uganda using a structured questionnaire and were analysed using the Statistical Package for Social Scientists.
Findings
The results indicate that relational agency is positively and significantly associated with relational people management. Findings further indicated that collective efficacy, mutual cooperation, shared learning and interaction enablement individually matter in relational people management.
Originality/value
To the best of the authors’ knowledge, this study may be among the first to demonstrate that relational agency and its individual dimensions (interaction enablement, shared learning, mutual cooperation and collective efficacy) foster relational people management in the context of micro and small enterprises of Uganda, an African developing country. Consequently, this study contributes to both theory and literature via the cultural historical activity theory, hence, adding to the scant existing literature on relational agency and relational people management.

Abstract
Dunkin’ Donuts is a global retailer of coffee and bakery products. The company is 99 per cent franchised and has used the franchising system as a route to market entry and expansion worldwide. The original historic roots of the company are in the USA and despite wide international expansion since the 1970s, the US market continues to serve as a testing ground for innovations prior to international roll‐out. Based on observation and key informant interviews with core members of the management team during a visit to Richmond Project in 1994, the case explores the initial phase of the introduction of a central production facility as an innovative route to pre‐eminence in one test market. Strategic and operational issues are discussed, highlighting the differences and efficiency gains of the central production facility cum satellite store approach compared to the traditional stand‐alone on‐site production approach. Implications for future developments are discussed.

Abstract
Tonya and Anete are new players at sc’MOI, but this theme emerges at the tail end of sc’MOI so they are best to explicate it. This chapter describes the theoretical contributions of quantum storytelling theory (QST) and practice. Building on the application of complexity theory in the hard sciences as well as social contexts and theory on multimodal constituency, this chapter considers the areas of overlap and difference between quantum storytelling and its theoretical fellows, with special attention given to sociomateriality, storytelling, feminism, fractal, and complexity theory.

Abstract
Purpose
The purpose of this study is to investigate the complexity of how demands and stress are mitigated to enhance employee performance in remote working arrangements.
Design/methodology/approach
A time-lagged snowball sample of 223 full-time remote working adults in the United States participated in an online survey. Data were analyzed using R 4.0.2 and structural equation modeling.
Findings
Results suggest remote job resources involving organizational trust and work flexibility increase performance via serial mediation when considering information communication technology (ICT) demands and work–life interference (WLI). The findings provide insights into counterbalancing the negative aspects of specific demands and stress in remote work arrangements.
Practical implications
This study provides insights for managers to understand how basic job resources may shape perspectives on demands and WLI to impact performance. Specific to remote working arrangements, establishing trust with the employees and promoting accountability with their work flexibility can play an important part in people and their performance.
Originality/value
This study contributes theoretically to the literature by evidencing how components of the E-Work Life (EWL) scale can be used with greater versatility beyond the original composite measurement because of the job-demand resource (JD-R) framework and conservation of resources theory (COR). This study answers several calls by research to investigate how ICT demands and WLI play a complex role in work performance.

Abstract
Purpose
The purpose of this paper is to explore how the emerging, post‐Newtonian twenty‐first century worldview, integrating elements of holistic Chinese philosophy and individualistic Western Newtonianism, is also driving a new model of organization, the articulation of which Chinese managers and thinkers must take a leadership position.
Design/methodology/approach
The author focuses, first, on the similarities between the worldviews of Chinese philosophy and post‐Newtonianism; second, on how those changes in worldview support the emerging model of organization, whose management style one writer refers to as “unmanaging”; and, third, on the benefits available for Chinese business people who apply their acculturated understanding of principles that still seem foreign to Western business people.
Findings
This essay asserts that the worldview emerging from twentieth century science – primarily quantum mechanics and complexity theory – will reinforce many of the basic assumptions basic to Chinese culture and philosophy. As a result, Chinese managers and thinkers have the opportunity to make critical contributions to an emerging model of organization, which Western management thinkers have been predicting for nearly half a century.
Practical implications
The paper offers a series of theoretical tools, taken from fields of study ranging from the philosophy of science to organizational dynamics, with which Chinese managers and thinkers can develop a leadership position in the discussion that has begun about what the author calls the post‐Newtonian organizational model.
Originality/value
The value of the essay lies in its integration of twentieth century science, Chinese philosophy and the study of organizations to indicate how Chinese managers and thinkers can help shape a new, trans‐cultural way of understanding organizations, markets and finally, the world.

Abstract
Purpose
For measuring the effect of crop root content on soil water retention curves (SWRC), a simulation approach (multi-gene genetic programming (MGGP)), which develops the model structure and its coefficients automatically can be applied. However, it does not perform well due to two vital issues related to its generalization: inappropriate formulation procedure of the multi-gene model and the difficulty in model selection. The purpose of this paper is to propose a heuristic-based-MGGP (N-MGGP) to formulate the functional relationship between the water content and two input parameters (soil suction and volumetric crop root content).
Design/methodology/approach
A new simulation approach (heuristic-based-MGGP (N-MGGP)), was proposed to formulate the functional relationship between the water content and two input parameters (soil suction and volumetric crop root content). The proposed approach makes use of a statistical approach of stepwise regression and classification methods (Bayes naïve and artificial neural network (ANN)) to tackle the two issues. Simulated data obtained from the models was evaluated against the experimental data.
Findings
The performance of proposed approach was found to better than that of standardized MGGP. Sensitivity and parametric analysis conducted validates the robustness of model by unveiling dominant input parameters and hidden non-linear relationships.
Originality/value
To the best of authors’ knowledge, an empirical model is developed that measures the effect of crop root content on the SWRCs. The authors also proposed a new genetic programming approach in simulating the crop root content dependent SWRCs.

Abstract
The purpose of this paper is to provide an overview of account planning by tracing its origins, development and role from its genesis to its current status. Account planning grew out of dissatisfaction with advertising agencies’ ability to meet the challenges they were facing in the early 1960s. It started out by combining elements of research and strategic planning to inform creative development and to provide the guidance and direction needed to use consumer insight to drive successful creative solutions. Since those early beginnings, a changing advertising environment has fuelled account planning’s exodus as it has been adopted internationally and by marketing communications fields that extend beyond advertising. While the paper brings us to the current day, account planning continues to evolve. It is expected that the trend of adoption by a range of marketing communications specialist agencies will persist but that a new account planning “revelation” will be in the form of independent strategy consultancies and increased client activities.
