Abstract
Purpose
This paper aims to introduce a new perspective on long-term stock return predictability by focusing on the relative (individual and hybrid) informative power of a wide range of accounting (firm-related), technical and macroeconomic factors while considering the past performance of the stocks using machine learning algorithms.
Design/methodology/approach
The sample includes a panel data set of 94 non-financial firms listed in Egyptian Exchange 100 index from 2014: Q1 to 2019: Q4. Relativity has been investigated by comparing relevant factors’ individual and combined informative power and differentiating between losers and winners based on historical stock returns. To predict the quarterly stock returns, Gaussian process regression (GPR) has been used. The robustness of the results is examined through the out-of-sample test. This study also uses linear regression (LR) as a benchmark model.
Findings
The past performance and the presence of other predictors influence the informative power of relevant factors and hence their predictive ability. The out-of-sample results show a trade-off between GPR and LR with proven superiority to GPR in limited experiments. The individual informative power outperforms the hybrid power, in which macroeconomic indicators outperform the remaining sets of indicators for losers, while winners show mixed results in terms of various performance evaluation metrics. Prediction accuracy is generally higher for losers than for winners.
Practical implications
This study provides interesting insight into the dynamic nature of the predictor variables in terms of stock return predictability. Hence, this study also deepens the understanding of asset pricing in a way that directly contributes to practitioners’ portfolio diversification strategies.
Originality/value
In concern of the chaos of factors in the literature and its accompanying misleading conclusions, this study takes another look at the approach that studies stock return predictability. To the best of the authors’ knowledge, this is the first study in the Egyptian context that re-examines the predictive power of the previously discovered factors from a different perspective that highlights their relative nature.

Abstract
Purpose
This paper aims to clarify the resistance degree of group road logistics to flood disaster resilience. The paper measures the resilience of group road logistics by establishing network structure model. The purpose of this study is to improve the resilience of road log.
Design/methodology/approach
This paper adopts Delphi method to collect data, interviews mainly flood management experts and supply chain risk management experts, and then analyzes the data through the network structure model combined with interpretative structure model (ISM) and analytical network process (ANP).
Findings
The results show that flood frequency and drainage systems are the main factors affecting the resilience of road transport logistics in urban areas. These research results provide useful guidance for the effective planning and design of urban road construction and infrastructure.
Research limitations/implications
However, the main factors affecting the resilience of road transport logistics are likely to change with the development of factors such as climate, economy and environment. Therefore, in future work, the authors' research will focus on the further application of this evaluation method.
Practical implications
The results show that the impact of flooding on the four dimensions of road logistics resilience varies. This shows that in deciding what intervention measures are to be taken to improve the resilience of the road network to flooding, various measures need to be considered.
Social implications
This paper provides a more scientific analysis of the risk management ability of the road network in the face of floods. In addition, it also provides a useful reference for urban road planners.
Originality/value
This paper addresses a clear need to study how to build models to improve the resilience of road logistics in flood risk.

Abstract
Purpose
Organizational wicked problems are ill-defined phenomena arising in complex environments with intertwined and evolving interests. This paper aims to use a nonlinear epistemological approach to explore how multiple management decision tools work together to form configurational paths to deal with organizational wicked problems and to propose some heuristic toolkits for tackling them.
Design/methodology/approach
Based on interviews with 53 senior executives dealing with 62 organizational wicked problems, this paper uses grounded theory to construct an antecedent theoretical framework and then uses qualitative comparative analysis (QCA) to conduct configuration analysis on the strategy portfolios that can tackle organizational wicked problems.
Findings
This paper used grounded theory to identify six theoretical dimensions as management decision tools for dealing with organizational wicked problems: change adaptation, goal performing, administration, mechanical integration, organic integration and entrepreneuring. In addition, this paper used QCA to explore and propose three heuristic toolkits – synergy oriented, institution oriented and innovation oriented – as multiple equivalent paths to help deal with organizational wicked problems.
Originality/value
This paper uses configuration analysis instead of the net effect analysis of the traditional econometric method and captures multiple antecedent conditions for decision-makers to deal with organizational wicked problems from a holistic perspective. This paper constructs three heuristic toolkits and matches each of them with the most suitable type of organizational wicked problem, constructing a complete research chain of “identifying–tackling” the organizational wicked problem and providing a reference for organizations facing similar situations in future practice.

Abstract
Purpose
The paper introduces the autoethnography as a healing and everyday resistance strategy for marginalized voices. The focus is to deliver the author’s own reflections on some key moments and experiences to stimulate the discussion on autoethnography as a critical instrument channeling one’s reflexivity in the higher education context.
Design/methodology/approach
The paper draws on a case study of Chinese academic professionals to inspire the discussion on the research and practical values of autoethnography. It also provides conceptual reflections on the political meaning and functions of autoethnography.
Findings
The paper highlights two key aspects of autoethnography in the higher education context. Firstly, it emphasizes the importance of autoethnography in navigating the personal political front. Secondly, it promotes the integration of autoethnography into the ordinary lives of overseas Chinese academic professionals for daily healing and resistance.
Originality/value
The paper explores political sensitivity as an important dimension of workplace ethnography. Recognizing political sensitivity avows autoethnography a political act and a research framework, through which the (auto)ethnographer examines his or her own principles for negotiating justice and interpreting the ownership of personal identity against the influx of politically-charged opinions from the surrounding.

Abstract
Purpose
This research objective was to explore how Romanian IT family businesses' co-founders enable entrepreneuring through familiness practices. The authors explored what familiness practices emerge and how these are facilitated and supported by the rhetoric framework.
Design/methodology/approach
Drawing on Romanian IT entrepreneurs' practice from five case studies of IT family businesses and purposive revelatory cases, the authors considered the family co-founders' narratives and representations of familiness presented in 31 interviews.
Findings
The respondents' communication in entrepreneuring is a joint collaborative effort of the family co-founders to function well. Family entrepreneurs generate positive perceptions in favour of enterprising families using persuasive communication via rhetoric appeals to familiness ethos, familiness logos and familiness pathos, leading to constructive conflict management. The rhetoric of persuasion supports family entrepreneuring.
Research limitations/implications
The authors conducted multiple case studies, profiling technological co-founders and family entrepreneurs in the challenging circumstances of an emerging economy.
Practical implications
The analysis of the use of rhetoric contributes to a better understanding of familiness practices in the family business. Through appeals to ethos, family business entrepreneurs enforce family values built on shared history, complementarity and moral exemplarity. The appeals to logos in entrepreneuring involve fulfilling complementary roles, alignment and continuous learning and coaching. The appeals to pathos are about emotions and how the family entrepreneurs' discourse enforces constructive handling of emotions.
Social implications
The perceived familiness communicated through appeals to ethos, logos and pathos contributes to legitimating the family firm structures.
Originality/value
Theorising from family entrepreneurs' familiness practices, the authors suggest that entrepreneuring requires good communication of the representation of familiness for co-founders, employees and other stakeholders to also serve constructive conflict handling. The perceived familiness communicated through appeals to ethos, logos and pathos helps family businesses leverage their unique strengths and resources in the entrepreneuring process.

Abstract
Purpose
This paper aims to suggest a multi-theoretical explanation using a success story to explain psychological well-being (PWB) among employees of K.C, a small enterprise found in Uganda, a developing country in Africa.
Design/methodology/approach
The study used qualitative methodology. Based on in-depth interviews with K.C employees, a story was developed describing the practical experience, focusing on the context, actions, results and lessons learnt. Regarding the sample size, the saturation point was attained on the seventh participant.
Findings
Findings reveal that employees that possess psychological capital set targets and generate avenues that allow them to achieve set goals, with personal initiative that makes them proactive to accomplish work tasks and individual adaptability that enables them to adjust their emotions and behavior to fit in a complex working environment, which makes them to think, feel and act positively. Furthermore, several theories, including broaden and build, personal initiative and complex adaptive systems theory, explain the manifestations of PWB of employees in small enterprises.
Research limitations/implications
The study was limited by focusing on the context of a small enterprise. Future research may investigate other study contexts whose findings might be different. In addition, the study being hypothetical lacked statistical testing. It would be a meaningful effort if future studies statistically tested the suggested model. Irrespective of the limitations, the findings of this study remain significant.
Practical implications
In practice, employees may replicate these findings to nurture PWB which eventually contributes to enterprises’ success. This could provide answers to the psychological challenges experienced by employees of small enterprises, especially in the African developing countries like Uganda where this is a major challenge. Specifically, the workers of K.C enterprise may depend on their PWB to deal with workplace challenges and sustain the enterprise’s performance.
Social implications
Socially, there is need to embrace positive social relationships among employees at the work place which will translate into well-being of society.
Originality/value
This paper is exceptional because it uses a success story showing practical experiences of how PWB of employees in small enterprises is nurtured in Uganda. In addition, a multi-theoretical perspective is used to explain the manifestations in the story, which is the greatest contribution of this paper. Further, a conceptual model is still proposed, depicting psychological capital, personal initiative and individual adaptability as antecedents of PWB.

Abstract
Purpose
This study aims to examine the effect of structural transformation on poverty alleviation in Sub-Saharan Africa (SSA) countries with a higher share of services as a percentage of gross domestic product (GDP). The study specifically focuses on the value-added share as a percentage of GDP in the agricultural, manufacturing, industrial, and service sectors using time series data from 1988 to 2019.
Design/methodology/approach
The study utilizes the autoregressive distributive lag (ARDL) bound test framework for estimation, based on the conclusions drawn from the augmented Dickey-Fuller and Phillips–Perron unit root tests, which provide evidence of a mixed order of integration.
Findings
The result reveals that agriculture value-added (AVA), manufacturing value-added (MVA), industrial value-added (IVA), and services value-added (SVA) have a positive and significant impact on poverty alleviation in both the short and long run. However, the agriculture sector is found to be more effective in reducing poverty compared to the other sectors examined in this study. Additionally, this study challenges the notion that SSA countries have undergone an immature structural transformation. Instead, it reveals a pattern of stagnant structural transformation, as indicated by the lack of growth in the industrial and manufacturing value-added shares of GDP.
Practical implications
To enhance productivity and reduce poverty, SSA economies should adopt a development strategy that prioritizes heavy manufacturing and industrial sectors, leading to a transition from the agricultural to the secondary and tertiary sectors.
Originality/value
The study contributes to the emerging literature on structural transformation by investigating which sector is more efficient in reducing poverty in SSA countries, using the value-added share as a percentage of GDP for agricultural, manufacturing, industrial, and service sectors. The study also aims to determine if SSA countries have experienced immature structural transformation due to the growing share in the service sector.

Abstract
Purpose
This study is focused on achieving operational resilience through the practices of kaizen across the operational structure. The research is based on a case study of a commercial livestock farm in Nigeria. The study views the practice of kaizen from the perspective of the commitment of the members of the case study organisation who are directly involved with the operations of the organisation.
Design/methodology/approach
The study applies a qualitative approach to explore the topic, engaging members of the case study organisation in the research to gather relevant data on the implementation of kaizen practices and the drive to attain resilience in the case study organisation. Semi-structured personal interviews and workshops were used for data collection. The study adopts systems theory to explore the topic, identifying and engaging relevant stakeholders.
Findings
Parts of the findings relating to kaizen are the issues with the livestock production process, aggressive leadership and the issue of livestock mortality in the case study organisation. These were discussed based on extant literature. The study affirms the importance of organisational members' commitment and adequate leadership support to achieve sustainable kaizen practices. The study highlights the need to align kaizen practices with relevant organisational practices, such as reward systems and contextual requirements for its implementation in an operational process. The study suggests that further study can focus on the dynamics of the legal system on the implementation of kaizen, especially from a developing economic background like Nigeria, where this study was conducted.
Originality/value
The study projects learning about the spatial factors that can affect the practices of kaizen in critical sectors like livestock management.

Abstract
Purpose
The purpose of this paper is to share findings from empirically driven conceptual research into the implications for English teachers of understanding generative AI as a “tool” for writing.
Design/methodology/approach
The paper reports early findings from an Australian National Survey of English teachers and interrogates the notion of the AI writer as “tool” through intersectional feminist discursive-material analysis of the metaphorical entailments of the term.
Findings
Through this work, the authors have developed the concept of “coloniser tool-thinking” and juxtaposed it with First Nations and feminist understandings of “tools” and “objects” to demonstrate risks to the pursuit of social and planetary justice through understanding generative AI as a tool for English teachers and students.
Originality/value
Bringing together white and First Nations English researchers in dialogue, the paper contributes a unique perspective to challenge widespread and common-sense use of “tool” for generative AI services.

Abstract
Purpose
Based on the social exchange theory, the aim of the present study is to examine the effects, both direct and indirect (through sustainability-oriented innovative behaviors [SIBs]), of sustainable project leadership (SPL) on sustainable project performance (SPP). Project management approaches (PMAs) (traditional, hybrid and agile) were examined as conditional factors in the “SPL–SIBs” relationship.
Design/methodology/approach
The study employs structural equation modeling based on data collected from 197 software engineering project team members working in the financial industry in Poland.
Findings
The study revealed that SPL significantly, positively affected SPP. It also provided evidence for the significant mediating impact of SIBs in the relationship between SPL and SPP and the conditional effect of agile and hybrid PMAs on the “SPL–SIBs” relationship.
Originality/value
The novelty of this work lies in introducing sustainable leadership into project management research, proposing and testing a unique and complex research framework, designing valid scales for measuring SPL and SPP, and suggesting many theoretical and empirical implications.
