Abstract
Purpose
This study aims to examine the causal and reciprocal relationships between participation in travel and recreational activities and depression alleviation among survivors of traumatic events. It seeks to uncover the transformative potential of these activities as nonpharmacological interventions and to provide insights that inform the therapeutic design of travel in rehabilitation contexts.
Design/methodology/approach
Using a longitudinal dataset, this study employs the random intercept cross-lagged panel model – a robust technique for evaluating causal relationships in nonexperimental longitudinal research – to assess the reciprocal effects between travel and recreation participation and depression severity over time.
Findings
Individuals with more severe depression are more likely to engage in travel as a coping mechanism. However, travel does not inherently alleviate depressive symptoms, likely because its physical and emotional demands often outweigh its benefits. This highlights the need to transform travel into structured interventions to maximize therapeutic potential. In contrast, recreational activities exhibit a stronger therapeutic effect, with early participation reducing depressive symptoms and lower depression levels, subsequently encouraging continued engagement in recreation over time.
Originality/value
By highlighting the interplay between social causation and social withdrawal theories, this research proposes transforming travel experiences into structured therapeutic interventions, pioneering a new perspective on integrating health and tourism studies. The study encourages researchers to adopt a holistic approach to understanding the health benefits of travel, considering both the influence of external factors on health and how individuals respond to their psychological state.
研究目的
本研究旨在深入探讨创伤事件幸存者参与旅行与娱乐活动与抑郁症状缓解之间的因果和相互作用关系, 旨在揭示这些活动作为非药物干预的潜在疗效, 并为康复场景下旅行的治疗性设计提供理论依据和实践参考。
研究方法
本研究利用纵向数据集, 采用随机截距交叉滞后面板模型(RI-CLPM)进行分析。该方法是一种适用于非实验性纵向研究的模型工具, 能够有效评估旅行与娱乐活动参与和抑郁严重程度之间的双向动态影响。
研究结果
研究发现, 抑郁程度较高的个体更倾向于将旅行作为一种应对机制。然而, 由于旅行活动的身体与情感成本通常超过其潜在收益, 旅行本身并未显著缓解抑郁症状。这表明, 需要将旅行体验转化为结构化的治疗干预, 以充分发挥其潜在价值。相较而言, 娱乐活动表现出更显著的治疗作用。早期参与娱乐活动能够有效降低抑郁症状, 而抑郁水平的降低反过来又会激励个体持续参与娱乐活动, 从而形成良性循环。
研究创新
本研究通过结合社会因果理论和社会退缩理论, 提出了有必要将旅行体验转化为结构化治疗干预的新视角, 为健康与旅游研究的整合提供了新的理论创新路径。同时, 本研究倡导从整体视角理解旅行的健康益处, 兼顾外部环境对健康的影响以及个体心理状态对行为的反馈作用, 为未来研究提供了重要启示。
Propósito
Este estudio tiene como objetivo examinar las relaciones causales y recíprocas entre la participación en actividades de viaje y recreación y el alivio de la depresión entre los sobrevivientes de eventos traumáticos. Busca descubrir el potencial transformador de estas actividades como intervenciones no farmacológicas y proporcionar ideas que informen el diseño terapéutico de viajes en contextos de rehabilitación.
Métodos
Utilizando un conjunto de datos longitudinales, este estudio emplea el Modelo de Panel Cruzado con Intercepto Aleatorio (RI-CLPM), una técnica robusta para evaluar relaciones causales en investigaciones longitudinales no experimentales, para analizar los efectos recíprocos entre la participación en viajes y recreación y la gravedad de la depresión a lo largo del tiempo.
Resultados
Las personas con depresión más severa tienden a participar en viajes como mecanismo de afrontamiento. Sin embargo, el viaje en sí no alivia inherentemente los síntomas depresivos, probablemente porque sus demandas físicas y emocionales suelen superar sus beneficios. Esto resalta la necesidad de transformar los viajes en intervenciones terapéuticas estructuradas para maximizar su potencial. En contraste, las actividades recreativas muestran un efecto terapéutico más fuerte, con una participación temprana que reduce los síntomas depresivos y niveles más bajos de depresión que fomentan la participación continua en recreación a lo largo del tiempo.
Originalidad
Al destacar la interacción entre las teorías de causalidad social y retirada social, esta investigación propone transformar las experiencias de viaje en intervenciones terapéuticas estructuradas, abriendo una nueva perspectiva para integrar estudios de salud y turismo. El estudio fomenta que los investigadores adopten un enfoque holístico para comprender los beneficios de salud de los viajes, considerando tanto la influencia de factores externos en la salud como cómo las personas responden a su estado psicológico.

Abstract
Purpose
This study aims to propose a rapid optimization design framework for the electric propulsion system of tiltrotor aircraft with a comprehensive set of propeller and motor parameters.
Design/methodology/approach
To enhance the prediction accuracy, the authors have developed correction models for both the propeller and motor, i.e. the propeller performance model is based on blade element momentum theory, with the Reynolds-averaged Navier–Stokes method to obtain blade airfoil aerodynamic data, and the motor performance model incorporates an experimentally corrected second-order equivalent circuit model. Using Bayesian optimization algorithms, the authors have addressed the mixed-integer nonlinear programming design problem, which includes discrete variables such as the number of propeller blades and blade airfoil type, as well as continuous variables such as propeller diameter, pitch angle, chord length distribution, twist angle distribution, initial motor resistance, no-load current and KV value.
Findings
To estimate the aircraft-level performance, the authors have integrated the electric propulsion system into the tiltrotor’s overall mission profile, where an energy consumption reduction of 34.1% for the mission profile can be achieved after propeller and motor simultaneous optimization.
Originality/value
This study provides a valuable tool for the preliminary design and optimization of the electric propulsion systems for tiltrotor aircraft.

Abstract
Purpose
Political factors play a crucial role in China's initial public offering (IPO) market due to its distinctive institutional context (i.e. “economic decentralization” and “political centralization”). Given the significant level of IPO underpricing in China, we examine the impact of local political uncertainty (measured by prefecture-level city official turnover rate) on IPO underpricing.
Design/methodology/approach
Using 2,259 IPOs of A-share listed companies from 2001 to 2019, we employ a structural equation model (SEM) to examine the channel (voluntarily lower the issuance price vs aftermarket trading) through which political uncertainty affects IPO underpricing. We check the robustness of the results using bootstrap tests, adopting alternative proxies for political uncertainty and IPO underpricing and employing subsample analysis.
Findings
Local official turnover-induced political uncertainty increases IPO underpricing by IPO firms voluntarily reducing the issuance price rather than by affecting investor sentiment in aftermarket trading. These relations are stronger in firms with pre-IPO political connections. The effect of political uncertainty on IPO underpricing is also contingent upon the industry and the growth phase of an IPO firm, more pronounced in politically sensitive industries and firms listed on the growth enterprise market board.
Originality/value
Local government officials in China usually have a short tenure and Chinese firms witness significantly severe IPO underpricing. By introducing the SEM model in studying China IPO underpricing, this study identifies the channel through which local government official turnover to political uncertainty on IPO underpricing.

Abstract
Purpose
Consumers often face trade-offs between important product attributes. Previous research suggests that individuals tend to prioritize attribute differences that are easily processed and aligned. This paper aims to examine the contexts in which nonalignable attribute differences can positively impact consumers’ perceptions of products.
Design/methodology/approach
Four lab experiments were conducted to explore how consumer preferences for superior-alignable versus superior-nonalignable products vary based on purchase occasions, with a specific focus on routine and special occasions.
Findings
Consumers tend to prefer superior-nonalignable products on special occasions and superior-alignable products on routine occasions. This is driven by stronger uniqueness motives on special (vs routine) occasions, as consumers associate nonalignable attribute differences more closely with product specialness. The research also explores the moderating roles of consumers’ need for uniqueness (NFU) and psychological ownership. Consumers with higher levels of NFU consistently prefer superior-nonalignable products, regardless of the occasion type. Additionally, when consumers feel psychological ownership of products with superior-alignable attributes, the perceived specialness of these products increases, reducing the influence of occasion type on consumer preferences for attribute alignability.
Originality/value
This research emphasizes the importance of aligning product attribute differences with specific purchase occasions in marketing strategies.

Abstract
Purpose
This study aims to examine the relationship between managerial ability and innovation efficiency, the mediating effect of digital transformation and the moderating effect of internal control.
Design/methodology/approach
This study collected A-share manufacturing listed companies in China from 2008 to 2019 and analyzed the data by means of multiple regression analysis, mediating effect test, moderating effect test and heterogeneity test. Finally, the authors conducted robustness test by remeasuring key variables and adding control variables.
Findings
The empirical results show that the higher managerial ability can improve innovation efficiency, internal control has a positive moderating effect and digital transformation plays a partial mediating effect on the relationship between managerial ability and innovation efficiency. Specially, it is found that the mediating effect of digital transformation is not significant in non-state-owned firms.
Practical implications
This study suggests that it is necessary to focus on the managerial ability in terms of both cultivation and supervision, to further deepen the digital transformation from the aspects of firms, government and society, especially to support the digital transformation of non-state-owned firms, and to make efforts to improve the corporate governance mechanism and internal control system, so as to better comprehensively realize the improvement of enterprise innovation efficiency.
Originality/value
Based on the mediating effect analysis of digital transformation and the moderating effect analysis of internal control, this study explores the role of managerial ability on innovation efficiency from a new perspective, expanding the related theoretical framework and research boundaries.

Abstract
Purpose
Tacit and explicit knowledge sharing play crucial roles in today’s rapidly changing business environment, particularly in fostering innovation. However, uncovering tacit knowledge sharing remains complex. The purpose of this study is to analyze the mediating roles of tacit and explicit knowledge in the relationship between a knowledge-sharing culture and organizational creativity.
Design/methodology/approach
In this study, the authors developed an extended analytical process to analyze the impact of explicit and tacit knowledge on a knowledge-sharing culture and organizational creativity. This process combines two analytical techniques: necessary condition analysis (NCA) and partial least squares structural equation modeling (PLS-SEM). NCA identifies essential bottlenecks for a specific outcome, while PLS-SEM uncovers strong connections between predictor and outcome variables. The authors applied these analyses to a sample of 155 IT experts from a leading telecom company in the Turkish ICT industry to test the relevant hypotheses.
Findings
The findings of this study indicate that tacit knowledge, rather than explicit knowledge, partially mediates the relationship between a knowledge-sharing culture and organizational creativity. This mediating role of tacit knowledge is particularly pronounced in the ICT sector. Additionally, the impact of organizational capabilities on organizational creativity is amplified by higher levels of tacit knowledge sharing.
Originality/value
The effect of organizational capabilities on organizational creativity was found to increase because of tacit knowledge sharing compared to explicit knowledge sharing, depending on the knowledge-sharing climate.

Abstract
Purpose
This study investigates the nonlinear relationship between inventory leanness and ESG (environmental, social and governance) performance, exploring how market concentration and digital transformation moderate this connection in manufacturing enterprises.
Design/methodology/approach
Using a large panel data collected from Chinese listed manufacturing enterprises over the period from 2012 to 2021, this research employs the instrumental variable method combined with two-stage least squares estimators to explore the U-shaped relationship between inventory leanness and ESG performance. Furthermore, the moderating roles of market concentration and digital transformation are demonstrated.
Findings
The results reveal an inverted U-shaped relationship between inventory leanness and ESG performance, indicating that moderate lean inventory management enhances ESG outcomes, but excessive reduction hinders them. Additionally, market concentration and digital transformation positively moderate this relationship, suggesting that competitive market conditions and technological advancement mitigate the adverse effects of overly lean inventories.
Practical implications
Managers are advised to balance inventory management with market dynamics and embrace digital transformation to optimize ESG performance. Policymakers can leverage these insights to guide firms in sustainable inventory practices.
Originality/value
This study contributes to the literature by unveiling the nonlinear dynamics between inventory leanness and ESG performance and highlighting the moderating roles of market concentration and digital transformation.

Abstract
Purpose
While the impact of digitalization on businesses has been extensively studied, the influence of digitalization on marketing outcomes in private enterprises has not received sufficient attention. The current study aims to examine how and when digitalization affects international marketing decisions in the context of private enterprises.
Design/methodology/approach
This study employs data from a survey of Chinese private enterprises conducted in 2020, which constitutes the world's largest dataset of its kind. Nearly 19,000 samples were included in the study. Additionally, we also incorporate supplementary data on digitalization in the Chinese region. Employing various methods, this study empirically and robustly examines the proposed research framework within the context of Chinese private enterprises.
Findings
Based on the resource-based view and agency theory, this paper found that digitalization can positively impact private enterprises’ direct and indirect international marketing decisions. Furthermore, we introduce the inclusion of innovation capacity and board governance as moderators in the model and find that board governance attenuates the influence of digitalization on international marketing decisions, while innovation capacity enhances the impact of digitalization on direct international marketing but diminishes its effect on indirect international marketing.
Originality/value
This study advances the understanding of the impact of digitalization on international marketing in private enterprises, thereby addressing the gap in the limited focus on digitalization in private enterprises. It also demonstrates how private enterprises effectively utilize digitalization to gain marketing advantages in the international market.

This study aims to investigate the mechanical and tribological behavior of 70Mn steel with different laser re-melted textured patterns.
Abstract
Purpose
This study aims to investigate the mechanical and tribological behavior of 70Mn steel with different laser re-melted textured patterns.
Design/methodology/approach
Laser surface re-melting (LSR) was used to manufacture various textured patterns (i.e. line, grid and mixed) on both the original and heat-treated 70Mn steel plates. The micro-hardness, microstructure, tensile strength, yield strength, elongation, coefficients of friction (COF) and worn morphologies were characterized to evaluate the impact of different textured patterns on the overall performance.
Findings
The results show that re-melted unit exhibited the highest surface hardness on the subsurface. The increase in surface hardness of the re-melted unit for the heat-treated 70Mn steel samples was much lower than that of the original ones. The re-melted textured patterns did not improve the tensile strength, yield strength and elongation of either original or heat-treated 70Mn steel samples. The re-melted textured patterns effectively reduced the average COFs of heat-treated 70Mn steel samples, but increased friction of the non-heat-treated samples.
Originality/value
This study provides valuable insights into enhancing the mechanical properties and tribological characteristics of 70Mn steel, particularly in the automotive, heavy machinery and high-load application sectors. These industries have stringent requirements for durability and friction control, and the findings of this research are expected to effectively extend the lifespan of mechanical components.

Abstract
Purpose
As an ancient art form, embroidery has strong practicality and artistic value. However, current embroidery style migration models produce images with unclear textures and a lack of stitch detail. So, in this paper, we propose a cyclic consistent embroidery style migration network with texture constraints, which is called Texture Cycle GAN (TCGAN).
Design/methodology/approach
The model is based on the existing Cycle GAN network with an additional texture module. This texture module is implemented using a pre-trained Markovian adversarial network to synthesize embroidery texture features. The overall algorithm consists of two generative adversarial networks (for style migration) and the Markovian adversarial network (for texture synthesis).
Findings
Qualitative and quantitative experiments show that, compared with the existing convolutional neural network style transfer algorithm, the introduction of the texture-constrained embroidery style transfer model TCGAN can effectively learn the characteristics of style images, generate digital embroidery works with clear texture and natural stitches and achieve more realistic embroidery simulation effects.
Originality/value
By improving the algorithm for image style migration and designing a reasonable loss function, the generated embroidery patterns are made more detailed, which shows that the model can improve the realism of embroidery style simulation and help to improve the standard of embroidery craftsmanship, thus promoting the development of the embroidery industry.
