Purpose - The purpose of this study is to examine the effect of VC investment on the IPO and post-IPO performance of Chinese firms. Design/methodology/approach - By utilizing CSMAR and VentureXpert database, we construct a firm-year panel data covering all listed firms in the Chinese stock market from 2006 to 2018. Findings - First, we find that VC-backed firms are significantly less underpriced than non-VC-backed firms. Our results show that the initial IPO-day return of VC-backed firms is 0.16% lower than that of non-VC-backed firms. Next, we find that VC-backed firms demonstrate significantly worse operating performance than non-VC-backed firms after the IPO. In the next three years following the IPO, VC-backed firms underperform non-VC-backed firms by 0.4% in terms of ROA and by 0.6% in terms of ROE. Research implications or Originality - Our results support the Grandstanding Hypothesis, among several competing hypotheses regarding the effect of VC investment, which suggests that VCs window dress their IPO firms for their early exit at the expense of a poor operating performance of the IPO firms after going public.

Purpose: This study aimed to describe the process of developing a validated pediatric nursing simulation scenario template using the real-time Delphi method. Methods: A panel of 13 pediatric nursing experts participated in a real-time Delphi survey conducted over two rounds. Initially, 83 items were included in the questionnaire focusing on the structure and content of the simulation scenario template. Data analysis involved calculating the content validity ratio (CVR) and the coefficient of variation to assess item validity and stability. Results: Through iterative rounds of the Delphi survey, a consensus was reached among the experts, resulting in the development of a pediatric nursing simulation scenario template comprising 41 items across nine parts. The CVR values ranged from 0.85 to 1.0, indicating a high consensus among experts regarding the inclusion of all items in the template. Conclusion: This study presents a novel approach for developing a pediatric nursing simulation scenario template using real-time Delphi methods. The real-time Delphi method facilitated the development of a comprehensive and scientifically grounded pediatric nursing simulation scenario template. Our template aligns with the International Nursing Association for Clinical Simulation and Learning standards, and provides valuable guidance for educators in designing effective simulation scenarios, contributing to enhanced learning outcomes and better preparation for pediatric clinical practice. However, consideration of cultural and contextual adaptations is necessary, and further research should explore alternative consensus criteria.

Purpose - This study aims to explore the relationship between housing and land prices, with a specific emphasis on the impact of government policies on these factors such as land supply quantity and the ratio of residential land to total land supplied. The goal is to identify the most effective government intervention strategies for controlling both housing and land prices. Design/methodology/approach - Data from 70 primary and medium-sized cities in China spanning from 2003 to 2017 are utilized in this research. The analysis employs a panel vector autoregressive (PVAR) model, with a primary focus on examining the relationships among housing prices, land prices, and government intervention policies. Findings - Housing and land prices are influenced by various factors. Through impulse response analysis and variance decomposition, it is observed that both housing and land prices are predominantly influenced by their internal dynamics, with comparatively weaker effects attributed to policy interventions. Research implications or Originality - By investigating the impact of government policies on housing and land prices, This study establishes a foundation for effective price control measures. Our study advocates for a comprehensive examination of China's land supply mechanism to enhance understanding of the pathways through which government policies influence the markets.

Purpose - Low fertility rate is a serious problem, and this study analyzes factors affecting total fertility rate using panel data from 16 metropolitan cities and provinces in Korea from 2000 to 2022. Design/methodology/approach - Estimating the SAR model considering the weak cross-sectional dependence that exists in variables related to the regional total fertility rate, and using the DKSE estimation method considering the strong cross-sectional dependence. Findings - Estimation results considering weak and strong cross-sectional dependence were similar, confirming the robustness of the results. Female labor force participation rate has a positive effect on total fertility rate, and employment rate has no effect. However, the interaction term is a negative (-) sign. Crude marriage rate has a positive effect on total fertility rate, and apartment price has a slightly positive effect. Environmental factor has no effect, and policy factor has a negative effect. Research implications or Originality - In order for an increase in the female labor force participation rate to lead to an increase in the total fertility rate, qualitative improvements in female employment must be made. Financial investment policies for childbirth must increase their effectiveness. The problem of low fertility rate requires not only population policy but also social, economic, cultural, environmental, and policy conditions to be considered.

Purpose - This study aims to examine the relationship between high-performance work systems and organizational ambidexterity. Additionally, it seeks to verify the mediating effect of organizational cultural diversity on this relationship. Design/methodology/approach - The study tested four hypotheses using data from manufacturing companies with more than 100 regular workers, sourced from the Human Capital Corporate Panel (HCCP). For empirical analysis, the generalized least squares (GLS) estimation method was employed, and the hypotheses were verified using a probabilistic effects model. Findings - The study revealed that high-performance work systems improve organizational ambidexterity by enhancing organizational cultural diversity. Research implications or Originality - This study confirms the mediating effect of organizational cultural diversity between high-performance work systems and organizational ambidexterity, explaining how high-performance work systems influence organizational ambidexterity through organizational cultural diversity. Additionally, it identifies an organizational cultural variable that closely aligns with the academic concept of organizational ambidexterity. The study demonstrates that the core elements of high-performance work systems are instrumental in cultivating an organization that simultaneously pursues seemingly competitive heterogeneous values.

Our research seeks to assess the influence of nuclear energy technology on carbon emissions in the top 10 European economies comprising the topmost nuclear energy R&D budget (France, Germany, Russia, the Netherlands, the UK, Finland, Spain, Sweden, Italy, and Switzerland). Unlike prior investigations predominantly relying on panel data methodologies without considering the distinctive characteristics of each economy, our study employs the advanced 'Quantile-on-Quantile' approach. This novel methodology enables us to investigate the interactions between variables within each unique nation, thereby improving the precision of our analysis. As a result, the study provides a thorough global perspective, revealing nuanced findings pertinent to each economy's specific attributes. Our outcomes demonSstrate a positive interconnection between nuclear energy technology and carbon emissions across various quantiles in our analyzed nations. Additionally, the study highlights diverse patterns in these associations within individual economies. These findings emphasize the significance of policymakers performing comprehensive measurements and devising effective strategies to monitor fluctuations in nuclear energy technology and carbon emissions.
