Abstract
Purpose
To predict the price of battery-grade lithium carbonate accurately and provide proper guidance to investors, a method called MFTBGAM is proposed in this study. This method integrates textual and numerical information using TCN-BiGRU–Attention.
Design/methodology/approach
The Word2Vec model is initially employed to process the gathered textual data concerning battery-grade lithium carbonate. Subsequently, a dual-channel text-numerical extraction model, integrating TCN and BiGRU, is constructed to extract textual and numerical features separately. Following this, the attention mechanism is applied to extract fusion features from the textual and numerical data. Finally, the market price prediction results for battery-grade lithium carbonate are calculated and outputted using the fully connected layer.
Findings
Experiments in this study are carried out using datasets consisting of news and investor commentary. The findings reveal that the MFTBGAM model exhibits superior performance compared to alternative models, showing its efficacy in precisely forecasting the future market price of battery-grade lithium carbonate.
Research limitations/implications
The dataset analyzed in this study spans from 2020 to 2023, and thus, the forecast results are specifically relevant to this timeframe. Altering the sample data would necessitate repetition of the experimental process, resulting in different outcomes. Furthermore, recognizing that raw data might include noise and irrelevant information, future endeavors will explore efficient data preprocessing techniques to mitigate such issues, thereby enhancing the model’s predictive capabilities in long-term forecasting tasks.
Social implications
The price prediction model serves as a valuable tool for investors in the battery-grade lithium carbonate industry, facilitating informed investment decisions. By using the results of price prediction, investors can discern opportune moments for investment. Moreover, this study utilizes two distinct types of text information – news and investor comments – as independent sources of textual data input. This approach provides investors with a more precise and comprehensive understanding of market dynamics.
Originality/value
We propose a novel price prediction method based on TCN-BiGRU Attention for “text-numerical” information fusion. We separately use two types of textual information, news and investor comments, for prediction to enhance the model's effectiveness and generalization ability. Additionally, we utilize news datasets including both titles and content to improve the accuracy of battery-grade lithium carbonate market price predictions.

Abstract
Purpose
This study reveals the green building development path and analyzes the optimal government subsidy equilibrium through evolutionary game theory and numerical simulation. This was done to explore the feasible measures and optimal incentives to achieve higher levels of green building in China.
Design/methodology/approach
First, the practice of green building in China was analyzed, and the specific influencing factors and incentive measures for green building development were extracted. Second, China-specific evolutionary game models were constructed between developers and homebuyers under the market regulation and government incentive mechanism scenarios, and the evolutionary paths were analyzed. Finally, real-case numerical simulations were conducted, subsidy impacts were mainly analyzed and optimal subsidy equilibriums were solved.
Findings
(1) Simultaneously subsidizing developers and homebuyers proved to be the most effective measure to promote the sustainability of green buildings. (2) The sensitivity of developers and homebuyers to subsidies varied across scenarios, and the optimal subsidy level diminished marginally as building greenness and public awareness increased. (3) The optimal subsidy level for developers was intricately tied to the building greenness benchmark. A higher benchmark intensified the developer’s responsiveness to losses, at which point increasing subsidies were justified. Conversely, a reduction in subsidy might have been appropriate when the benchmark was set at a lower level.
Practical implications
The expeditious advancement of green buildings holds paramount importance for the high-quality development of the construction industry. Nevertheless, the pace of green building expansion in China has experienced a recent deceleration. Drawing insights from the practices of green building in China, the exploration of viable strategies and the determination of optimal government subsidies stand as imperative initiatives. These endeavors aim to propel the acceleration of green building proliferation and materialize high-quality development at the earliest juncture possible.
Originality/value
The model is grounded in China’s green building practices, which makes the conclusions drawn more specific. Furthermore, research results provide practical references for governments to formulate green building incentive policies.

Abstract
Purpose
The purpose of this study is to present an exploration of green intrinsic motivation’s mediating role in the relationship between socially responsible human resource management (SRHRM) and employee workplace green behaviour. Additionally, green leadership behaviour’s moderating role within this relationship is investigated.
Design/methodology/approach
Data were collected via a survey using a convenience sampling approach with a sample of 300 employees in Vietnam. A path analysis and the bootstrapping technique in the SPSS Process macro were used to test the hypotheses.
Findings
The results demonstrate that employee green intrinsic motivation mediates the association between SRHRM and workplace green behaviour. Furthermore, the findings indicate that green leadership behaviour attenuates the mediation.
Practical implications
The findings suggest that managers should be aware of green intrinsic motivation’s role in encouraging employee workplace green behaviour that results from SRHRM implementation. Organisations should provide resources and enact policies to promote green intrinsic motivation and foster employees’ engagement in workplace environmental activities. Additionally, organisations must be aware of the potentially negative impact of green leadership behaviour and proactively ensure that such actions are authentic, aligned with SRHRM practices, applicable to employees’ work and administered carefully to prevent the perception of micromanagement.
Originality/value
This is the first study to examine green intrinsic motivation as the underlying psychological mechanism and green leadership behaviour as the boundary condition that affects the relationship between SRHRM and employee workplace green behaviour.

Abstract
Purpose
The current business environment is characterized by high levels of uncertainty that affect the global economic system and have the greatest impact on small and medium-sized enterprises (SMEs). With an elevated degree of perceived uncertainty, Chief executive officers' (CEOs) of SMEs find themselves in a situation where the old approaches to decision-making are irrelevant and the time to create new ones is limited. The purpose of this study is to examine whether appealing to personal values helps CEOs cope with a high level of perceived uncertainty and make decisions about the further development of the firm by undertaking business model innovations (BMI).
Design/methodology/approach
This study follows a multiple case study research design drawing on data collected from 10 Russian SMEs.
Findings
The authors show that CEOs’ communion values lead to innovations in the revenue model and value architecture dimensions of the business model. CEOs who are inclined to agentic values introduce innovations in the revenue model and value offering dimensions. Those executives who balance between the two types of values tend to also balance between different types of innovations in the elements of the business model.
Originality/value
The results indicate that personal values of CEOs play an important role in managerial processes and the strategic choice of a BMI type. Moreover, personal temporal focus orientation serves as a translation mechanism in the relationship between CEO values and BMI in SME settings.

Abstract
Purpose
This study aims to explore the impact of green inclusive leadership (GIL) on green creativity (GCRY) within the context of higher education institutions (HEIs) in China. Specifically, it aims to examine the mediating roles of green intrinsic motivation (GIM), environmental knowledge (EK) and green thinking (GT) according to the componential theory of creativity (CTC).
Design/methodology/approach
The study employed a series of questionnaire surveys to collect data at three different time points from various sources. A total of 583 leader-faculty matched samples were obtained from two universities in China. The hypothesized relationships were tested using PROCESS macro in SPSS.
Findings
The findings indicate a beneficial influence of GIL on GCRY, mediated by GIM, EK and GT. Noteworthy interaction effects were observed, with GIM fostering EK and GT, and EK laying the groundwork for GT.
Practical implications
This research contributes to the existing literature by confirming the implementation of GIL and supporting the CTC, offering insights into the motivational processes driving GCRY and with practical implications discussed for the effective management of GIL and GCRY in higher education settings.
Originality/value
The novelty of this research model lies in its operationalization of environmental sustainability within the CTC. This study is the initial investigation highlighting the role of GIL in fostering GCRY within HEIs. The key contribution of the study is the investigation of GIM, EK and GT as potential mediators in the relationship between GIL and GCRY. This expands the theoretical boundaries of the CTC framework.

Abstract
Purpose
The purpose of this study is to find out the role of positive personality traits such as honesty-humility, emotionality, extraversion, agreeableness, conscientiousness and openness to experience (HEXACO) in the development of empowering leadership, and also determine the impact that mastery goal orientation and work engagement play in linking the effects of an empowering leader on the creative performance of their followers.
Design/methodology/approach
The quantitative research design is used along with a deductive approach to achieve the objectives of the study. Data from 337 employees in the telecom sector was collected through self-administered questionnaires using the purposive sampling method. SEM-AMOS methods were used to conduct the analysis, and regression analysis was used to test the formulated hypotheses.
Findings
The study’s findings indicated that each component of HEXACO (honesty-humility beta values = 0.086, p < 0.05, emotionality values as β = 0.275, p < 0.001, extroverts β = 0.217, p < 0.001, consciousness β = 0.277, p < 0.001 and agreeableness β = 0.063) played a significant role in fostering empowered leadership. The results also suggested that there is a sequential mediation of mastery goal orientation and work engagement in the relationship between empowering leadership and creative performance.
Originality/value
This study is unique since it covers the antecedents and outcomes of empowering leadership. For antecedents, the study used the HEXACO personality model with all its elements to identify its role in the development of empowering leadership. Moreover, the study also used mastery goal orientation and work engagement as sequential mediators to check the impact of empowering leadership on the creative performance of employees.

Abstract
Purpose
This paper aims to examine a range of factors that may influence the intention of ultra-micro-SMEs in Indonesia in choosing the type of microfinance facilities in the case of getting better offerings.
Design/methodology/approach
Drawing from the theory of planned behavior (TPB) framework, religious elements factors include religious leader endorsements, religiosity and Sharia compliance, whereas socially/commercially driven factors include social and rational sociodemographic indicators. Data was obtained from 319 ultra-micro-SMEs in emerging economies such as Indonesia, and structural equation modeling was used to analyze the survey data.
Findings
The findings reveal that commercial aspects, as rational variables, have a negative influence on the intention to switch from Islamic to conventional microfinancing. On the contrary, social influence from peers and family positively influences the intention to switch from Islamic to conventional microfinancing. Religious aspects, however, have no influence on the intention to switch or actual switching behavior from Islamic to conventional. Intention to switch was shown to positively influence actual switching behavior as per the prediction of the TPB.
Originality/value
There is a lack of research on the choice or behavior of ultra-micro-SMEs when deciding whether to use Islamic or conventional microfinance. This study enriches the literature by providing empirical evidence on the factors affecting this choice-making.

Abstract
Purpose
Recent literature in environmental management suggests that fostering employees’ innovative behaviour in green service is vital for enhancing the environmental sustainability of hospitality organizations. Despite this, few efforts have been made to understand how green entrepreneurial leadership (GEL) relates to green service innovative behaviour (GSIB). This study aims to examine whether GEL can promote GSIB among hospitality employees through the serial mediation of green learning orientation (GLO) and green knowledge acquisition (GKA) using the conservation of resources theory. The authors expect environmental dynamism to strengthen the relationship between GEL and employees’ GSIB, leveraging the resource-based view theory.
Design/methodology/approach
This study collected data through a multi-wave survey (four waves, two weeks apart) from 341 employees working in three-to-five-star hotels in Pakistan’s major cities. The authors used partial least squares structural equation modelling to evaluate the hypotheses proposed in the theoretical model.
Findings
The study revealed a significant relationship between GEL and employee GSIB, mediated by GLO and GKA. In addition, environmental dynamism strengthened the relationship of GEL with employee GSIB.
Originality/value
The research advances the literature on GEL in the hospitality sector by providing insights into the mediating and moderating processes that translate GEL into GSIB among hospitality employees. Moreover, the research provides important implications for hotels investing in green initiatives and looking for ways to foster employees’ GSIB.
