Abstract
Purpose
The primary purpose of this study is to investigate the relationship between leader bottom-line mentality (BLM) and employee innovative behavior, which may be interpreted by employees’ perceived creativity expectations and moderated by employee time orientation.
Design/methodology/approach
A multi-wave and multi-source questionnaire survey with 259 paired Chinese employee–leader dyads provided data to test the theoretical model. Hypotheses were tested with Statistical Package for the Social Sciences (SPSS).
Findings
Consistent with hypotheses, leader BLM reduces employees’ perceived creativity expectations and thus inhibits employees’ innovative behavior, and this effect is stronger for employees with short-term orientation.
Practical implications
Our findings highlight the negative influences of leader BLM on innovative behavior and the buffering role of employees’ long-term orientation. Organizations may incorporate BLM in leadership promotion and evaluation and provide corresponding training for leaders to overcome BLM. In addition, long-term orientation can be a valuable indicator in employee recruitment and selection.
Originality/value
This study contributes to a new theoretical perspective of the Pygmalion effects for understanding leader BLM’s influence on employee innovative behavior.

Abstract
Purpose
Given the current friction and wear challenges faced by automobile parts and bearings, this study aims to identify a novel texture for creating anti-friction and wear-resistant surfaces. This includes detailing the preparation process with the objective of mitigating friction and wear in working conditions.
Design/methodology/approach
Femtosecond laser technology was used to create a mango-shaped texture on the surface of GCr15 bearing steel. The optimized processing technology of the texture surface was obtained through adjusting the laser scanning speed. The tribological behavior of the laser-textured surface was investigated using a reciprocating tribometer.
Findings
The friction coefficient of the mango-shaped texture surface is 25% lower than that of the conventional surface, this can be attributed to the reduced contact area between the friction ball and the micro-textured surface, leading to stress concentration at the extrusion edge and a larger stress distribution area on the contact part of the ball and disk compared to the conventional surface and the function of the micro-texture in storing wear chips during the sliding process, thereby reducing secondary wear.
Originality/value
The mango-shaped textured surface in this study demonstrates effective solutions for some of the friction and wear issues, offering significant benefits for equipment operation under light load conditions.

Abstract
Purpose
This study conducts a systematic literature review on the determination of urban land value to offer a comprehensive understanding of the methods, datasets, themes and factors of land value. The study aims to identify research gaps and suggest directions for future research in urban land value.
Design/methodology/approach
The study adopts the systematic literature review (SLR) approach to synthesize the literature on urban land value. The SLR is structured according to a three-stage protocol, involving planning, conducting and reporting to ensure transparency and reproducibility. Quantitative bibliometric analysis and qualitative hierarchical thematic analysis are used to assess the evolution of research and to identify key themes and factors.
Findings
The study reveals an unbalanced research focus on developed economies and residential land in urban land value literature. A hierarchical framework categorizes 644 factors into 25 subthemes and 8 themes across physical dimensions (e.g. land attributes and structure attributes) and market dimensions (e.g. land market and macroeconomic conditions). Two primary estimation methods – regression and residual – are identified, each suitable based on data availability. The literature’s evolution is driven by advances in empirical methods. An extensive catalog of databases is compiled, and a corresponding menu of methods is discussed with a focus on empirical identification strategies.
Research limitations/implications
The study is limited by the focus on urban land value and the exclusion of agricultural, recreational and transportation land. Future research should expand to other land types and integrate new data sources and advanced methodologies such as machine learning to enhance empirical robustness.
Practical implications
The systematic review provides a foundation for practical applications and policy discussions on land value estimation and taxation. It offers a useful catalog of land value databases and a menu of land evaluation methods. They are useful for real estate businesses to perform accurate land evaluations and investment appraisals. They can also assist governments in determining precise land value for tax assessments and public policy formulation.
Originality/value
This paper is among the first to apply the SLR approach to urban land value – the price of an essential asset owned by households, businesses and governments. A key contribution is the identification of two distinct evolution patterns of literature: a “pine tree” pattern, showing linear, accumulative growth using homogeneous methodologies (e.g. regression methods) and a “palm tree” pattern, where diverse methods (e.g. residual methods) form independent branches. This analysis provides a new perspective on how methodological homogeneity influences the structure of research themes, offering insights into the dynamics of knowledge development in the field and in general.

Abstract
Purpose
Employability skills training programmes are an effective means for reducing unemployment rates. Such programmes also have the potential to improve the general well-being (e.g. self-efficacy) of disadvantaged individuals, however, reliable longitudinal evaluations of the psychological benefits of such programmes are limited. The present study evaluated the impact of an employability programme offered to disadvantaged adults in North-West England on self-efficacy. Additionally, the study aimed to identify risk factors for programme disengagement to identify at-risk groups that require further support.
Design/methodology/approach
Secondary longitudinal data pertaining to the background characteristics, programme engagement and self-efficacy scores (repeatedly measured on a monthly basis) of 308 programme users were analysed.
Findings
Results demonstrated that employability programme engagement significantly increased self-efficacy scores. Additionally, the findings suggested that individuals with mental health and learning difficulties were more likely to disengage from the programme. The findings demonstrate that employability programmes can have a positive impact on the well-being of individuals from disadvantaged backgrounds, however, prolonged engagement is needed for which some individuals require further support with.
Originality/value
The present study analysed longitudinal data from a diverse sample of disadvantaged individuals to reliably evaluate psychological outcomes from employability training programmes.

Abstract
Purpose
Drawn from the push–pull perspective, this research aims to identify the determinants of Chinese technology's outward foreign direct investments (OFDI) into the Eurasian region.
Design/methodology/approach
The authors argue that contrary to the extant literature, technology-driven OFDI from emerging-market multinationals (EMNEs) do not always seek developed countries, and EMNEs' technology investments in emerging economies are rising indicating that there are factors in these economies that can prove attractive. The authors recognize the influence of the macroeconomic environment and the interaction of home and host-country institutional contexts that influence the location choice of EMNEs technology-driven OFDI into other emerging economies, mediated by the industry sector and firm's ownership structure. The authors test our hypotheses using a sample of 1,656 observations of Chinese MNEs' tech-investments in the Eurasian region from 2005 to 2019.
Findings
The study results indicate that bilateral diplomatic relations pave the way of the host-country institutional environment for Chinese MNEs uncovering the role of the Chinese government as an OFDI facilitator. This study also unveils a lower technology level of the Chinese MNEs' investments in the Eurasian region connoting an interest in market opportunities exploitation through their existing technologies – through its comparative advantage in the global markets – rather than strategic assets acquisition aiming at augmenting their technological capabilities. This trend is similar to that of other major foreign direct investment (FDI) source countries.
Originality/value
This research contributes to a better understanding of the characteristics and the location choice of technology investments from EMNEs into other emerging economies that have received scant attention in the literature. In addition, it extends the institutional theory by analyzing how home-country institutions, through bilateral diplomatic relations, may smooth the host country institutional environment for home-country MNEs' foreign investments and contributes as well to the debate on the applicability of the existing theoretical framework in the case of emerging-market MNEs.

Abstract
Purpose
In view of the unknown environmental parameters and uncertain interference during gripping by the manipulator, it is difficult to obtain an effective gripping force with the traditional impedance control method. To avoid this dilemma, the purpose of this study is to propose an adaptive control strategy based on an adaptive neural network and a PID search optimization algorithm for unknown environments.
Design/methodology/approach
The method is based on a variable impedance model, and a new impedance model is established using a radial basis function (RBF) neural network to estimate unknown parameters of the impedance model. The approximation errors of the adaptive neural network and the uncertain disturbance are effectively suppressed by designing the adaptive rate. In the meantime, auxiliary variables are constructed for Lyapunov stability analysis and adaptive controller design, and PSA is used to ensure the stability of the adaptive impedance control system. Based on the Lyapunov stability criterion, the adaptive im-pedance control system is proved to have progressive tracking convergence property.
Findings
Through comparative simulations and experiments, the superiority of the proposed adaptive control strategy in position and force tracking has been verified. For objects with low flexibility and light-weight (such as a coke, a banana and a nectarine), this control method demonstrates errors of less than 10%.
Originality/value
This paper uses RBF neural networks to estimate unknown parameters of the impedance model in real-time, enhancing system adaptability. Neural network weights are updated online to suppress errors and disturbances. Auxiliary variables are designed for Lyapunov stability analysis. The PSA algorithm is used to adjust controller parameters in real-time. Additionally, comparative simulations and experi-ments are designed to analyze and validate the performance of controller.

Abstract
Purpose
This study aims to fabricate the reduced graphene oxide (rGO)/ethylene vinyl acetate copolymer (EVA) composite films with electric-driven two-way shape memory properties for deployable structures application. The effect of dicumyl peroxide (DCP) and rGO on the structure and properties of the rGO/EVA composite films were systematically investigated.
Design/methodology/approach
The rGO/EVA composite films were fabricated by melting blend and swelling-ultrasonication method, DCP and rGO were used the crosslinking agent and conductive filler, respectively.
Findings
The research results indicate that the two-way shape memory properties of rGO/EVA composite films were significantly improved with the increase of DCP content. The rGO endowed rGO/EVA composite films with excellent electric-driven reversible two-way shape memory and anti-ultraviolet aging properties. The sample rGO/EVA-9 can be heated above Tm within 8 s at a voltage of 35 V and can be heated above the Tm temperature within 12 s under near-infrared light (NIR). Under a constant stress of 0.07 MPa, the reversible strain of the sample rGO/EVA-9 was 8.96% and its electric-driven shape memory behavior maintained great regularity and stability.
Research limitations/implications
The rGO/EVA composite films have potential application value in the field of deployable structures.
Originality/value
With the increase of DCP content, the two-way shape memory properties of rGO/EVA composite films were significantly improved, which effectively solved the problem that the shape memory properties of EVA matrix decreased caused by swelling. The rGO endowed rGO/EVA composite films with excellent electric/NIR driven reversible two-way shape memory properties.

Abstract
Purpose
This paper aims to explore how corporate diversification influences corporate cash holdings (CCH) in India. It also assesses CCH behavior and its determinants during crisis, stability and recovery periods.
Design/methodology/approach
The study uses the system generalized method of moments (System GMM) on 1684 non-financial firms listed on the National Stock Exchange during 2002–2022. Further analyses are carried out for group-affiliated firms based on investment cash flow sensitivity, agency costs and debt capacity.
Findings
The findings show that firm diversification (at the group level) results in a roughly 6% fall in cash ratio, thereby implying that diversified firms (diversified business groups) hold lower cash levels than specialized firms. The reduced cash balances are attributed to the financially unconstrained nature of diversified business groups, higher debt capacity, good governance behavior and active internal markets. Additionally, the authors observe a time-varying cash policy for diversified firms, with mean cash holdings being 2% higher during crisis periods. Moreover, the findings reveal that the inverse relationship between diversified firms and CCH is less pronounced for unrelated diversified firms (2% fall in cash ratio) than related diversified firms (5% fall in cash ratio).
Originality/value
To the best of the authors’ knowledge, this is the first study to examine the relationship between corporate diversification and CCH in India during both crisis and non-crisis periods. The authors’ research uniquely uses System GMM on a large sample and differentiates between related and unrelated diversification.

Abstract
Purpose
This study aims to explore the relationship between managerial ownership and environmental innovation, particularly focusing on the impact of minority shareholder protection within the context of China’s A-share listed companies.
Design/methodology/approach
The study employs a fixed effect model over a decade-long sample, analysing secondary data from nonfinancial Chinese A-share firms. The two-stage least squares (2SLS) method is adopted to address endogeneity concerns.
Findings
The results demonstrate a significant positive influence of managerial ownership on environmental innovation, suggesting that top managers who have a say in the boardroom are inclined towards sustainable development. The presence of minority shareholders' protection positively moderates this relationship, underlining their roles in fostering environmentally friendly development. The subsample analysis showed that these relationships vary between state-owned enterprises (SOEs) and non-SOEs. It also differs between heavily and lightly polluting industries, which indicates that it is not enough to just have internal self-management, and more external pressure is necessary in heavily polluting industries.
Research limitations/implications
Our study underscores the importance for managers to recognize the potential of aligning their ownership interests with environmental objectives. Companies can enhance their commitment to sustainability by fostering an internal environment that supports minority shareholder rights.
Originality/value
This study specifically focuses on the role of top managers and minority shareholders, providing new empirical evidence on how their influence can drive sustainable development initiatives. It is also among the few studies that differentiate between firm characteristics and pollution intensity, which provides valuable insights into how the impact of managerial ownership and minority shareholder protection varies across different contexts.
