To motivate the supplier to exert more corporate social responsibility (CSR) effort, the manufacturer offers it either a revenue sharing contract or a cost sharing contract. We study the contract choice of the manufacturer.

We develop game theoretic models to investigate the manufacturer’s optimal contract choice and examine whether there is a conflict of contract preference between the manufacturer and the supplier.

First, the revenue sharing contract has more strict conditions regarding the unit cost of the supplier’s CSR effort and the manufacturer’s retail price. Second, the cost sharing contract enables the manufacturer to achieve a “win-win” performance in terms of both profitability and CSR effort. Finally, the supplier prefers the cost sharing contract when the manufacturer’s price is low, otherwise, it prefers the revenue sharing contract.

Differing from the papers on CSR, our paper focuses on the supplier CSR management problem, and analyzes the optimal contract to motivate the supplier to exert more CSR effort.

As information technology advances, the prevalence of AI chatbot products is on the rise. Despite optimistic market projections, consumer skepticism towards these agents persists. This paper aims to expand the scope of the technology acceptance model by integrating the aspect of appearance. It examines the influence of different attributes of AI chatbot, such as usefulness, ease of use and appearance, individually and in combination, on consumers' intentions to share and purchase.

Using an exploratory study of Web Texts, a 2 (usefulness: high vs low) × 2 (ease of use: high vs low) mixed design and a 2 (usefulness: high vs low) × 2 (ease of use: high vs low) × 2 (anthropomorphism appearance: humanoid vs cartoon) for between-subjects designs and the price level (high vs low) for within-subjects designs. The hypotheses were tested by Octoparse and SPSS 22.0.

The research highlights the significant role of usefulness, ease of use and anthropomorphic appearance in shaping consumer attitudes towards AI chatbots, thus influencing their intentions to share information and make purchases. Grouped regression analysis reveals that lower prices exert a more pronounced positive influence on consumers' inclinations to both share and purchase, compared to higher prices. Moreover, novelty-seeking behavior moderates the effect of perceived usefulness or ease of use on attitude. Specifically, heightened novelty-seeking tendencies mitigate the impact of low perceived usefulness or ease of use, leading to sustained positive attitudes towards AI chatbots among consumers.

This study innovatively incorporates product appearance into the Technology Acceptance Model (TAM), considering both the functional attributes and appearance of AI chatbot and their impact on consumers. It offers valuable insights for marketing strategies, extends the scope of TAM application and holds significant practical implications for enhancing enterprise product planning.

随着信息技术的进步, AI聊天机器人产品的普及正在增长。尽管市场对这些代理人持乐观态度, 但消费者对这些代理人的怀疑仍然存在。本文旨在通过整合外观方面来扩展技术接受模型的范围。它考察了AI聊天机器人的不同属性（如有用性、易用性和外观）对消费者分享和购买意图的影响, 单独以及组合。

使用Web文本的探索性研究, 一个2（有用性：高vs低）× 2（易用性：高vs低）的混合设计和一个2（有用性：高vs低）× 2（易用性：高vs低）× 2（人格化外观：类人形vs卡通）用于受试者间设计和价格水平（高vs低）用于受试者内设计。通过 Octoparse 和 SPSS 22.0 测试假设。

研究突出了有用性、易用性和拟人化外观在塑造消费者对AI聊天机器人态度方面的重要作用, 从而影响了他们分享信息和购买的意图。分组回归分析显示, 相对于高价格, 低价格对消费者分享和购买的倾向产生了更为显著的正面影响。此外, 新奇寻求行为调节了感知有用性或易用性对态度的影响。具体来说, 增强的新奇寻求倾向减轻了对低感知有用性或易用性的影响, 导致消费者对AI 聊天机器人持续保持积极态度。

本研究将产品外观创新地纳入技术接受模型（TAM）中, 考虑了AI 聊天机器人的功能属性和外观以及它们对消费者的影响。它为营销策略提供了有价值的见解, 拓展了TAM的应用范围, 并对增强企业产品规划产生了重要的实际影响。

The purpose of this paper is to design a climbing robot connected by a connecting rod mechanism to achieve multi-functional tasks such as obstacles crossing and climbing of power transmission towers.

A connecting rod type gripper has been designed to achieve stable grasping of angle steel. Before grasping, use coordination between structures to achieve stable docking and grasping. By using the alternating movements of two claws and the middle climbing mechanism, the climbing and obstacle crossing of the angle steel were achieved.

Through a simple linkage mechanism, a climbing robot has been designed, greatly reducing the overall mass of the robot. It can also carry a load of 1 kg, and the climbing mechanism can perform stable climbing. The maximum step distance of the climbing robot is 543 mm, which can achieve the crossing of angle steel obstacles.

A transmission tower climbing mechanism was proposed by analyzing the working environment. Through the locking ability of the screw nut, stable clamping of the angle steel is achieved, and a pitch mechanism is designed to adjust the posture of the hand claw.

This study aims to realize the multipurpose use of inorganic materials in adsorption treatment of pigment wastewater and preparation of core-modified Color Index Pigment Red 57:1 (C.I. Pigment Red 57:1, PR 57:1).

In this paper, the inorganic materials (sepiolite and SiO₂·nH₂O) were used in both PR 57:1 production wastewater treatment and its core-modification. The inorganic material firstly adsorbed 3-hydroxy-2-naphthoic acid (bon acid) in the pigment wastewater to reduce chemical oxygen demand. Then, the inorganic material adsorbed with bon acid was reused to prepare core-modified PR 57:1.

In the pigment wastewater adsorption experiment, it was found that under pH = 3, the adsorption percentage of bon acid by inorganic material can reached up to 46.00%. The pigment characterization results showed that the core-modified PR 57:1 had a core-shell structure. Under UV light irradiation for 1 h, the core-modified PR 57:1 prepared with sepiolite and SiO₂·nH₂O showed total color difference ΔE value of 1.43 and 2.05, respectively, which was lower than that of unmodified PR 57:1 (ΔE = 2.89). In addition, the transmittance of pigment water suspension test results showed that the core-modified PR 57:1 showed better water dispersibility.

This paper attempts to develop a synergistic strategy based on the multipurpose use of inorganic materials in adsorption treatment of pigment wastewater and preparation of core-modified PR 57:1.

The purpose of this study is uncovering the connotative and symbolic meaning of “luxury-lite brands” [轻奢].

Applying mixed methods, this study conducted two studies: (1) a semiotic analysis of a focus group discussion and 10 interviews on luxury-lite brands and (2) a content analysis of 248 Weiblog posts from 10 luxury-lite brands in a two-month period.

Study 1 showed that luxury-lite brands are interpreted as foreign brands that serve people's needs for social presence, and symbolize youthfulness, tastefulness, and aspirations. Other descriptors of luxury-lite brands included unique design, and less than the best quality offered by luxury brand. Study 2 suggested brands are missing out on a wide range of stories that resonate with their core segments in their social media advertising.

Based on the definition of luxury-lite brands in the context of China proposed by the researchers, we recommend that managers broaden topics of stories, make more effort to create desirable symbolic brand meaning, and use social media to excite these young crowds.

Luxury-lite brands have been a cultural sign in the Chinese market projected to grow into an over 90 billion USD business by 2025. Therefore, an insightful understanding of the masstige market of China is a must for any Western masstige brand to be successful and competitive.

Based on the socially embedded model of thriving at work and using the Conservation of Resources theory, this study examines how different resources promote thriving at work. Thus, we investigate the mediating role of psychological capital, as a personal resource, in the positive relationship between social support, as a job resource, and thriving at work, as well as the impact of psychological safety climate, as an organizational resource, on thriving and its moderating role in the relationship between psychological capital and thriving at work.

Eighty correctional officers (NL2 = 80) completed self-reported questionnaires at the beginning of the study and throughout six consecutive weeks (NL1 = 480), yielding a multi-level dataset.

The results supported the proposed weekly mediated process, also confirming the fact that a psychosocial safety climate has a positive effect on thriving at work. However, no moderation of the psychosocial safety climate was found.

In an environment with social support, correctional officers are full of hope at work, resilient, confident, and optimistic, contributing to increased energy and learning. Also, supervisors should promote psychological well-being at work to increase thriving.

The contribution of this study pertains to exploring the relationship between the psychosocial safety climate and thriving at work, as well as the role that various resources play in promoting thriving among correctional officers.

The geological conditions of Longyang Reservoir are complex and it is located in strong earthquake area. In order to determine its seismic characteristics, the seismic response and residual deformation of embankment dam should be studied to provide calculation basis for dam design and construction.

Based on the geological survey data of Longyang Reservoir, the dam filling materials are tested by dynamic deformation tests, and the equivalent linear constitutive model parameters of the filling materials are obtained. Based on Duncan-Chang E-B model, the stress state of embankment dam in Longyang Reservoir before earthquake is calculated, and the dynamic response and earthquake residual deformation of embankment dam in Longyang Reservoir under earthquake condition are calculated by using equivalent linear model and Shen Zhu-jiang’s residual deformation model.

The results show that with the increase of dynamic shear strain, the dynamic shear modulus decreases and the damping ratio increases. The scatter plot between dynamic shear modulus and dynamic shear strain, and the scatter plot between damping ratio and dynamic shear strain under different confining pressures show strips. The calculation results shows that the acceleration of embankment dam in Longyang Reservoir increases with the increase of dam height, and the acceleration distribution has obvious amplification effect. Combined with the maximum dynamic shear strain during the earthquake and the state before the earthquake, the maximum vertical residual deformation of embankment dam in Longyang Reservoir is 2.98 cm which occurs at the top of the dam, calculated by the Shen Zhu-jiang’s residual deformation model.

Finite element calculation model parameters of embankment dam are obtained by dynamic triaxial tests. Seismic dynamic responses and residual deformation of embankment dam are analyzed. With the increase of dam height, the acceleration distribution shows an obvious amplification effect. The vertical displacement of embankment dam is larger along the dam axis and decreases in the upstream and downstream direction. The maximum horizontal displacement of embankment dam occurs in the middle of upstream and downstream dam slopes.

This paper's objective is to propose an integrated framework to investigate the adoption intention of mobile banking technology and to test it in the Brazilian context.

A total of 666 respondents from the most economically developed cities in Brazil were surveyed. The sample comprised 333 mobile banking users and 333 mobile banking non‐users. Partial least squares was used to analyze the proposed framework's construct relations.

The framework offers an integrated view, taking into account more predictors than other studies on the adoption of innovations. For non‐users, the framework was able to explain approximately 69 percent of the dependent variable (intention to adopt mobile banking) variation, which is a figure higher than those obtained in previous studies. However, for current users of mobile banking, only 27 percent of the dependent variable variation was explained by the framework. It was also observed that the predictors' influence over the criterion variable was different for each group of mobile banking users and non‐users.

The findings suggest that the proposed integrated framework offers a deeper understanding of the variables that influence the adoption of mobile banking.
