Abstract
Purpose
The purpose of this study is to advance the application of pulverised cow bone ash (PCBA) as a partial replacement of cement in soil stabilisation for the production of bricks. The study investigated the impact of PCBA substitution on the characteristic strength of clay bricks under variant curing media.
Design/methodology/approach
Dried cow bones were pulverised, and an energy-dispersive X-ray fluorescence test was conducted on PCBA samples to determine the chemical constituents and ascertain the pozzolanic characteristics. Ordinary Portland cement (OPC) and PCBA were blended at 100%, 75%, 50%, 25% and 0% of cement substitution by mass to stabilise lateritic clay at 10% total binder content for the production of bricks. The binder-to-lateritic clay matrixes were used to produce clay bricks and cylinders for compressive and splitting tensile strength tests, respectively.
Findings
The study found that PCBA and OPC have similar chemical compositions. The strength of the clay bricks increased with curing age, and the thermal curing of clay bricks positively impacted the strength development. The study established that PCBA is a suitable substitute for cement, up to 25% for stabilisation in clay brick production.
Practical implications
Construction stakeholders can successfully use a PCBA-OPC binder blend of 1:3 to stabilise clay at 10% total binder content for the production of bricks. The stabilised clay bricks should be cured at an elevated temperature of approximately 90°C for 48 h to achieve satisfactory performance.
Originality/value
The PCBA-OPC binder blend provides adequate soil stabilisation for the production of clay bricks and curing the clay bricks at elevated temperature. This aspect of the biomass/OPC binder blend has not been explored for brick production, and this is important for the reduction of the environmental impacts of cement production and waste from abattoirs.

Abstract
Purpose
The current landscape of management scholarship faces criticism for prioritising theoretical development over practical relevance, leading to a disconnect between academic research and industry practices or applications. By exploring Pavitt’s work, the authors aim to highlight the importance of contextual understanding in innovation processes and to advocate for recognising diverse scholarly contributions that challenge established norms. A pragmatic theorist and mentor to a whole generation of innovation science and policy scholars worldwide, especially in Europe, Keith Pavitt left a legacy that is insufficiently acknowledged. Ultimately, this paper seeks to bridge the gap between theory and practice and to defend an innovation management that is responsive to contemporary organisational challenges.
Design/methodology/approach
The authors review the most relevant works by Keith Pavitt as a practitioner and as a “pragmatic theorist” and his network of author relationships, including all papers, special issues and reports published after his passing. Then, the authors discuss how those seminal papers or reports have been used and could be used in the future. This paper argues for a balanced approach that integrates rigorous academic inquiry with practical insights, emphasising the contributions of Keith Pavitt as a pioneering figure in Innovation-as-Practice.
Findings
The authors highlight that much of the current understanding of science and policy of innovation can be traced back to Pavitt’s work and that many future debates about technology could be enhanced by considering his findings. He has the stature of a parental figure, and his taxonomy, based on practice and empirical data, much like other management analysis tools, is widely used but not widely recognised yet, especially by industry managers or employees.
Originality/value
This paper sheds new light on an unacknowledged transdisciplinary pioneer, whose work is situated at the intersection of theory and praxis in Innovation Management: Keith Pavitt. It also advocates for a more transdisciplinary and circumstantial historical approach to management scholars.

Abstract
Purpose
This paper aims to examine the effect of dividend policy on firm value for financial sector in an emerging country. Furthermore, it examines the moderating effect of IFRS adoption and the abolishment of mandatory dividend payment policy with considering the Lintner model of dividend smoothing.
Design/methodology/approach
Data were collected from 111 firms listed on Borsa Istanbul in the financial sector in Turkey over 1995–2017. Using an explanatory research design, this study performs various multivariate regression techniques to investigate the proposed relationships.
Findings
The outcomes demonstrate a positive and significant association between dividend policy and firm value. In addition, the relationship has strengthened after IFRS adoption, indicating that accounting information such as dividend-based ratios prepared under IFRS is more value relevant. The empirical outcomes supported the Lintner model, which is persistent with the signalling hypothesis. Moreover, the findings state that the abolishment of mandatory dividend payment in 2009 strengthened the association between dividend policy and firm value for financial institutions in Turkey.
Practical implications
These results provide an insight to the investors and managers that the effect of IFRS adoption and other policy changes could be greater on the association between dividend policy and firm value. The study empirically tests Lintner model of dividend smoothing for financial firms in an emerging economy.
Originality/value
This study contributes to the literature through providing vital insights on the relationship between dividend policy and firm value and empirically revisiting the Lintner model for financial sector in a developing economy, specifically Turkey. Furthermore, it addresses the influence of IFRS implementation on the association between dividend policy and firm value. These findings are robust to alternative sampling methods and to controlling for other factors which influence firm value.

Abstract
Purpose
The purpose of this study to improve the efficiency of customer acquisition and retention through the design of salary information disclosure mechanism.
Design/methodology/approach
This study develops a stylized game-theoretic model of delegating customer acquisition and retention, focusing on how firms choose delegation and wage information disclosure strategy.
Findings
The results confirm the necessity for enterprises to disclose salary information. When sales agents are risk neutral, firms should choose multi-agent (MA) delegation and disclose their wages. However, when agents are risk averse, firms may disclose the wages of acquisition agents or both agents in MA delegation, depending on the uncertainty of the retention market.
Originality/value
This paper contributes to the literature on delegation of customer acquisition and retention and demonstrates that salary disclosure can be used as a supplement to the incentive mechanism.

Abstract
Purpose
In the context of severe environmental pollution and resource shortage, this study aims to examine how knowledge flows affect the green activities of firms. Specifically, this paper explored whether the firms’ knowledge flows, namely, knowledge inflow (KIF) and knowledge outflow (KOF), play a moderating role in relationship between corporate environmental responsibility (CER) and green innovation in Chinese high-polluting firms.
Design/methodology/approach
The analysis was carried out based on a panel data set of 305 heavy-polluting Chinese listed firms from 2010 to 2020. Meanwhile, this paper adopted the fixed model to empirically attest the proposed hypotheses regarding the relationships among CER, knowledge flows and green innovation.
Findings
The results indicate that there is a U-shaped relationship between CER and green innovation, while the two dimensions of knowledge flows exert opposing effects on the nonlinear link between CER and green innovation. Specifically, KIF positively moderates the effect of CER on green innovation, whereas KOF negatively moderates the effect of CER on green innovation.
Originality/value
This study demonstrates how green innovation can be influenced by CER and, moreover, provides a more nuanced understanding of the value of knowledge management (KM) in firms’ green activities. In this way, this paper answers the call for understanding the importance of green transformation in the context of KM.

Abstract
Recently, the concept of frugal innovation (FI) has gained relevance in both academic and societal discourse. Whether disruptive frugal digital innovation is contributing to the growth of small and medium-sized businesses in Africa is a subject of debate. Generally speaking, frugal inventions are linked to developing nations where sizable consumer groups at the base of the pyramid have unfulfilled needs. Africa, a continent with growing economies, has witnessed a surge in disruptive FI, which makes this chapter an important discourse. Digital technologies such as the Internet of Things (IoT), social media, cloud computing, and Artificial Intelligence (AI) are finding their way in the market, and how it is affecting human development and small enterprises has been a subject for debate. This book chapter presents findings on how FI has led to sustainable human development and growth of micro, small-, and medium-sized enterprises (MSMEs) as revealed by a review of existing literature on the subject. According to findings from the literature, MSMEs' connections and interactions with partners, suppliers, and consumers have improved as a result of the adoption of disruptive digital platforms. Additionally, while operating in challenging settings in Africa, digital technologies offer certain intrinsic traits and information technology capabilities that allow firms to grow and flourish. Digital platforms are viewed as transparent, collaborative instruments that provide economic opportunities throughout the ecosystem. The results also show that disruptive digital technologies offer MSMEs an inexpensive, simple-to-use, and simple-to-deploy solution in order to compete with stronger incumbents across a range of industries.

Abstract
Purpose
This paper aims to investigate if, under which conditions, and with which consequences, nonfamily members have the perception of being discriminated against as a consequence of nepotism and adverse selection practices. This research also aims to investigate whether the carried-out role influences the perception of being discriminated against among nonfamily member employees.
Design/methodology/approach
A quantitative approach was carried out by adopting a structural equation model (SEM) analysis. The survey investigated a sample of Italian family SMEs (participating companies N = 186, total questionnaires collected N = 838).
Findings
Drawing on the multiple identities theory, findings show that role salience (RS) effectively contributes to reducing the unwanted effects of perceived discrimination (PD) among nonfamily member employees. In doing so, this study deepens the knowledge of nonfamily member employment conditions and their consequences on strategic outcomes such as organizational commitment (OC), organizational justice (OJ) and intention to quit (ITQ).
Research limitations/implications
By adopting a self-categorization approach, this study also advances current theoretical literature, as this methodological lens could help scholars further understand diversity in family business.
Practical implications
This study suggests it would be advisable to implement human resource management practices based on job rotation to promote cohesion and reduce perceived distances.
Social implications
SMEs are the most widespread type of firm in the world; as a consequence, avoiding PD among nonfamily member employees has general ethical relevance.
Originality/value
This study expands current literature by showing that RS plays an important role in determining levels of PD. This study also advances current literature by focusing on the impact of multiple identities on fairness and commitment at individual and group levels of analysis of family businesses.

Abstract
Purpose
This paper aims to decode how service descriptions contribute to consumer satisfaction in the peer-to-peer service context and how consumer clout interferes with such influence. Based on the expectation–confirmation theory, the authors hypothesise that lowered expectations induced by modest service descriptions strengthen the performance-satisfaction link. In addition, the authors posit that consumer clout influences the moderation effect of service descriptions.
Design/methodology/approach
The paper is an empirical study using data of Airbnb, a representative peer-to-peer service platform. The data includes all listings in San Francisco, where Airbnb is headquartered. A total of 5,567 listing descriptions with 241,791 review comments were analysed after removing non-English texts. The host descriptions and guest reviews are analysed with the Linguistic Inquiry and Word Count and Google Cloud. The Tobit and ordered logistic models were used for hypothesis testing.
Findings
Guests are more likely to give higher ratings when they feel positive about the accommodation services. Such effect is stronger for lower guest expectations induced by modest host descriptions, as lower expectations are more likely to generate positive surprise disconfirmation. The previous relationship is moderated by guest clout, as guests high in clout pay less attention to host descriptions and are less likely to be surprised.
Originality/value
The paper investigates the joint influence of service descriptions and consumer reviews on peer-to-peer service satisfaction. The paper conducted entity-level sentiment analysis to examine opinions expressed towards specific types of entities. The paper also explored how consumer clout moderates the relationship, a boundary condition that previous studies have not explored.
