This study aims to examine how dynamic pricing impacts customer perceptions of restaurants and sentiment toward prices via online reputation metrics. In addition, to deepen the debate on dynamic pricing, a novel definition is drawn by exploring the specific forms of discrimination that can manifest in different industries.

Leveraging a comprehensive data set of restaurant reviews sourced from TripAdvisor, the study focuses on restaurants affiliated with one of the largest groups of restaurants in Spain. We used a quasi-experimental method (difference-in-differences), to study how dynamic pricing strategies influence customers’ perceptions of value based on numerical ratings. Meanwhile, we used a Bidirectional Encoder Representations from Transformers model on the textual component of reviews to dissect the emotional nuances of dynamic pricing.

Results did not reveal a causal impact of dynamic pricing strategies on customers’ perceptions. Moreover, the sentiment analysis shows no heightened negative view after introducing dynamic pricing in restaurants compared to the control group. Contrary to what previous literature suggests, our findings indicate that implementing dynamic pricing does not adversely affect customers’ perceptions or sentiments regarding prices in restaurants.

The quasi-experimental setting of the study presents inherent challenges in establishing causality that require further investigation using controlled experimental settings. Nevertheless, our study reveals that restaurant customers do not perceive dynamic pricing as unfair. This finding is critical for restaurant managers when considering the implementation of dynamic pricing and revenue management strategies. In addition, our study highlights the importance of considering not only numerical ratings but customer sentiment analysis as well. This more holistic approach to assessing the impact of pricing strategies can give restaurant managers a deeper understanding of customer reactions. In addition, a more rigorous definition of dynamic pricing is provided, clarifying its nature and its distinction in using different price discrimination.

This study contributes to the evolving understanding of dynamic pricing strategies’ impact on customers’ perceptions and sentiments in the restaurant industry. It aims to fill the gap in understanding customer reactions to algorithmically determined prices (via revenue management systems such as DynamEat) in this industry. The combination of causal inference and sentiment analysis offers a novel perspective, shedding light on the nuanced connections between dynamic pricing implementation and customers’ emotions.

本研究考察动态定价如何通过在线声誉指标影响顾客对餐厅的感知和对价格的情绪。此外, 为了深化对动态定价的讨论, 通过探索不同行业中可能表现出的具体歧视形式, 提出了一个新的定义。

利用从TripAdvisor获取的餐厅评论的全面数据集, 研究聚焦于与西班牙最大的餐厅集团之一相关联的餐厅。我们采用了准实验方法（差异中的差异）, 研究动态定价策略如何根据数值评分影响顾客对价值的感知。同时, 我们运用BERT模型对评论的文本成分进行分析, 以解析动态定价的情感细微差别。

结果没有揭示动态定价策略对顾客感知产生因果影响。此外, 情绪分析显示, 在餐厅引入动态定价后, 与对照组相比, 没有增加消极观点。与以往文献所述相反, 我们的发现表明, 实施动态定价并不会对顾客对价格的感知或情绪产生负面影响。

研究的准实验设置存在确立因果关系的固有挑战, 需要通过控制实验设置进一步调查。尽管如此, 我们的研究揭示了餐厅顾客不认为动态定价不公平。这一发现对餐厅经理在考虑实施动态定价和收入管理策略时至关重要。此外, 我们的研究强调, 考虑顾客情绪分析和数值评分的重要性。这种更全面的方法评估定价策略的影响, 可以让餐厅经理更深入地理解顾客反应。此外, 提供了一个更严格的动态定价定义, 澄清了其性质及其在使用不同价格歧视中的区别。

本研究对于理解动态定价策略对餐厅行业顾客感知和情绪影响的不断发展有所贡献。它旨在填补对客户对算法确定的价格（通过收入管理系统（RMS）例如DynamEat）在此行业中反应的理解空白。因果推断与情绪分析的结合提供了新的视角, 揭示了动态定价实施与顾客情绪之间微妙的联系。

Este estudio examina cómo la fijación dinámica de precios impacta en las percepciones de los clientes de los restaurantes y en el sentimiento hacia los precios a través de métricas de reputación en línea. Además, para profundizar en el debate sobre la fijación dinámica de precios, se propone una definición novedosa explorando las formas específicas de discriminación que pueden manifestarse en diferentes industrias.

Utilizando un conjunto de datos exhaustivo de reseñas de restaurantes obtenidas de TripAdvisor, el estudio se centra en los restaurantes afiliados a uno de los mayores grupos de restaurantes en España. Empleamos un método cuasiexperimental (diferencias en diferencias) para estudiar cómo las estrategias de precios dinámicos influyen en las percepciones de valor de los clientes basándonos en las calificaciones numéricas. Mientras tanto, empleamos un modelo BERT en el componente textual de las reseñas para desentrañar los matices emocionales de la fijación dinámica de precios.

Los resultados no revelaron un impacto causal de las estrategias de precios dinámicos en las percepciones de los clientes. Además, el análisis de sentimiento no muestra una visión negativa aumentada después de introducir la fijación dinámica de precios en los restaurantes en comparación con el grupo de control. Contrariamente a lo que sugiere la literatura previa, nuestros hallazgos indican que la implementación de precios dinámicos no afecta negativamente las percepciones o los sentimientos de los clientes respecto a los precios en los restaurantes.

La configuración cuasiexperimental del estudio presenta desafíos inherentes para establecer la causalidad que requieren una investigación más profunda utilizando entornos experimentales controlados. Sin embargo, nuestro estudio revela que los clientes de restaurantes no perciben la fijación de precios dinámica como injusta. Este hallazgo es crítico para los gerentes de restaurantes al considerar la implementación de la fijación de precios dinámica y estrategias de gestión de ingresos. Además, nuestro estudio resalta la importancia de considerar no solo las calificaciones numéricas sino también el análisis del sentimiento del cliente. Este enfoque más holístico para evaluar el impacto de las estrategias de precios puede dar a los gerentes de restaurantes una comprensión más profunda de las reacciones de los clientes. Además, se proporciona una definición de fijación de precios dinámica más rigurosa, aclarando su naturaleza y su distinción en el uso de diferentes discriminaciones de precios.

Este estudio contribuye a la comprensión en evolución del impacto de las estrategias de fijación de precios dinámicos en las percepciones y sentimientos de los clientes en la industria restaurantera. Su objetivo es llenar el vacío en la comprensión de las reacciones de los clientes a los precios determinados algorítmicamente (a través de sistemas de gestión de ingresos (RMS) como DynamEat) en esta industria. La combinación de inferencia causal y análisis de sentimientos ofrece una perspectiva novedosa, arrojando luz sobre las conexiones matizadas entre la implementación de la fijación de precios dinámicos y las emociones de los clientes.

Given the growing significance of contemporary socio-economic and infrastructural conversations of Public-Private Partnerships (PPP), this research seeks to provide a general overview of the academic landscape concerning PPP.

To offer a nuanced perspective, the study adopts the Latent Dirichlet Allocation (LDA) methodology to meticulously analyse 3,057 journal articles, mapping out the thematic contours within the PPP domain.

The analysis highlights PPP's pivotal role in harmonising public policy goals with private sector agility, notably in areas like disaster-ready sustainable infrastructure and addressing rapid urbanisation challenges. The emphasis within the literature on financial, risk, and performance aspects accentuates the complexities inherent in financing PPP and the critical need for practical evaluation tools. An emerging focus on healthcare within PPP indicates potential for more insightful research, especially amid ongoing global health crises.

This study pioneers the application of LDA for an all-encompassing examination of PPP-related academic works, presenting unique theoretical and practical insights into the diverse facets of PPP.

This study aims to explore and unfold the problems in designing and delivering employer-initiated financial education programs (FEPs) from the perspective of working women who attend such programs.

The researchers conducted in-depth interviews and utilized an interpretive qualitative approach to explore the expectations and experiences of women employees regarding such programs.

The results of this study demonstrate that employer-led FEPs may not benefit women employees due to specific misaligned actions of both employers and employees at every stage, which make the programs ineffective.

While this study encompasses women from varied age groups and marital statuses, the researchers acknowledge that the sample size is limited and represents a specific socioeconomic group.

The findings of this study have policy and practical implications for addressing perceived issues in FEPs initiated by employers for women employees.

The novel contributions of this study include suggesting a process model for building FEPs, highlighting the existing problems at each step in designing and delivering an FEP and expanding the application of Self-Determination Theory in FEPs.

The purpose of this study is to propose a comprehensive model of a hybrid organizational structure through action research, aiming to fill a gap in the literature on organizational structure implementation. The focus is on designing a model that integrates structural elements (centralization and specialization) and a non-structural element (competence), emphasizing operational efficiency and innovation capacity. The study was conducted in the production scheduling and control department (PSC) of a manufacturing company, with quantitative results demonstrating the feasibility of the proposed model.

The study employs an action research approach to develop a hybrid organizational structure model in three phases comprising ten steps. It focuses on integrating structured elements like centralization and specialization, alongside a non-structural component, competence. The research was conducted within the PSC of a manufacturing firm. This methodological framework facilitates the systematic design and implementation of the organizational structure model, allowing for a comprehensive analysis of its impact on performance indicators.

The quantitative results of the action research revealed a 3% increase in Overall Equipment Efficiency (OEE) and a 4% improvement in On Time/In Full (OTIF) performance metrics. These findings demonstrate the effectiveness and feasibility of the hybrid organizational structure model implemented in the PSC. The structured elements (centralization and specialization) combined with the non-structural element (competence) contributed to enhancing operational efficiency and meeting production goals, underscoring the significance of aligning organizational structure with strategic objectives for improved performance in dynamic competitive environments.

This study contributes to the literature by addressing the gap in research on implementing organizational structures. It offers a novel approach through action research, proposing a comprehensive model of a hybrid organizational structure. By integrating structured elements (centralization and specialization) with a non-structural element (competence), the model enhances operational efficiency and innovation capacity. The quantitative findings demonstrate the model’s effectiveness in improving performance metrics, emphasizing its value in guiding organizational design processes. This research underscores the importance of aligning organizational structures with strategic objectives to foster competitiveness and adaptability in dynamic business environments.

This study employed the viewer factors of live streamers on Instagram to influence the attachment and flow and then to investigate the impact of live streamer viewers’ relatedness needs satisfaction and entertainment needs satisfaction.

This study emphasized target audiences who followed live streamers on Instagram. We employed quota sampling to dispatch questionnaires on social media platforms. Therefore, 600 valid samples were collected in Taiwan and analyzed using structural equation modeling.

Empirical results show that the major route was from cognitive curiosity positively influencing attachment, then primarily positively affecting followers’ relatedness needs satisfaction. The empirical results also indicate that social media dependency positively influenced attachment, then contributing to viewers’ entertainment needs satisfaction.

Future research should explore various social media platforms (e.g. Line, Twitter, YouTube) to compare differences. Studies could also examine cross-national attitudes toward live-streaming and brands due to cultural or religious factors. With more funding, future research should increase sample sizes beyond 600 to reduce statistical bias. Additionally, incorporating homophily between viewers and live streamers into the viewer model on Instagram is recommended for further investigation.

This study is the novelty to enlarge the influences of emotional connection to two types of needs satisfaction when highlighting that perceived loneliness, cognitive curiosity and social media dependency positively affect needs satisfaction through attachment and flow in live streamer recommendations.

The aim of this research is to gain insight into the emotional impact and cognitive evaluations that these applications have on users from their own perspective.

Sentiment analysis methodology is used to analyze users’ comments and ratings, assess perceived benefits and determine the emotional impact these applications have on them.

The results suggest a benefit for happiness scholars, professionals, users and organizations focused on employee well-being and provide valuable insights into the evolving landscape of happiness applications. While the study relies on publicly available user data, it complements, but does not replace, market research or product evaluation conducted by app developers and companies.

Among the myriad channels disseminating the assumption that the good life is attainable through personal means and psychological know-how, smartphone applications have emerged as accessible, cost-effective and attractive tools to help users become happier and alleviate feelings of distress and discomfort.

Referring to transaction costs theory, resource based view and social exchange theory, this paper examines the interplay between selected dimensions of suppliers’ relationships with foreign buyers, specifically relational trust, contract specificity and relationship-specific investments, as well as analyzes the effects those dimensions have on the suppliers’ product innovation.

This study uses survey data from 179 small- and medium-sized Polish manufacturing suppliers of high-tech products. Information was collected on dyadic relationships with their key foreign buyers and used as an input to a structural model consisting of multiple linear regressions.

It was discovered that trust and investments have a mutual positive impact on each other and individually contribute to the supplier’s product innovation. However, once both trust and investments were included in the model, only the latter showed significant effect. Contracts, on the other hand, showed different impact on innovation depending on how it was measured.

Managers should treat trust only as a mechanism to create supportive environment for investments, which exclusively have the power to improve supplier’s product innovation. Contracts’ role, in turn, should be limited to facilitating business relationships.

Only single quantitative studies analyzed trust, investments and contracts as determinants of supplier’s product innovation. Also, focus was not placed on high-tech SMEs in relationships with foreign buyers. As a result, our study provides unique insights on such relationships and unveils new details on an indirect link between trust and product innovation.

Research on the impact of the engagement of online medical teams (OMTs) on patient evaluation, for example, satisfaction, remains insufficient. This study attempts to recognize the underlying mechanism of how OMTs’ engagement influences patient satisfaction by adopting social support as the mediator. This study also scrutinizes the moderating effects of the transactive memory system (TMS) on the link between OMTs’ engagement and social support.

We utilized a linear model that had fixed effects controlled at the team level for analysis. A bootstrapping approach using 5,000 samples was employed to test the mediation effect.

Our results reveal that OMTs’ engagement improves informational and emotional support, thereby promoting patient satisfaction. Specialization and credibility strengthen the impact of OMTs’ engagement on informational and emotional support. Simultaneously, coordination has an insignificant influence on the link between OMTs’ engagement and social support.

This study contributes to the literature on OMTs, social support, and TMS, providing insights into patients’ perceptions of OMTs’ engagement during online team consultation. This study also generates several implications for the practice of online health communities and OMTs.

People with visual impairments or blindness (PwVIB) are mostly excluded from tourism activities. Despite the rise of assistive technology (AT) solutions in Tourism, acceptance remains low because of the difficulty of providing the right functionality, effectiveness and usability. Arguably, it can be said that disability-oriented training can affect the latter two and, therefore, an AT solution’s acceptance. This paper aims to contribute to the theory development and conceptualization of technology acceptance of AT solutions in Tourism by studying, in the context of the Unified Theory of Acceptance and Use of Technology (UTAUT), the effects of training PwVIB on using AT solutions. This study presents the effects of training on the tourism behavior of PwVIB and provides valuable information to the stakeholders.

Questionnaire data collected from 128 PwVIB after evaluating an AT were subjected to exploratory and confirmatory factor analysis and structural equation modeling followed by post-evaluation interviews. The used application, called BlindMuseumTourer, enables high-precision autonomous indoor navigation for PwVIB in tourist places like museums and places of health care.

The results of this study indicate the partial satisfaction of the extended model validating the importance of performance expectancy and training (the new factor) in predicting the behavioral intention of PwVIB tourists toward using ATs during their tourist activities. This suggests that practitioners have to provide performant technological solutions accompanied by special training sessions for improved engagement and satisfaction.

This study contributes to the UTAUT theory in the context of Tourism for PwVIB by adding a new factor and replacing two moderator variables. To the best of the authors’ knowledge, no similar work is studying AT acceptance by PwVIB in the tourism literature. Furthermore, the validation process used a novel indoor navigation application, demonstrating its effectiveness in the Tactual Museum of Greece.

视障或失明人士（PwVIB）大多被排除在旅游活动之外。尽管辅助技术（AT）解决方案在旅游业中兴起, 但由于难以提供适当的功能、有效性和可用性, 接受度仍然很低。可以说, 以残疾为导向的培训会影响后两者, 从而影响对辅助技术解决方案的接受程度。本文旨在通过在技术接受和使用统一理论（UTAUT）的背景下, 研究培训 PwVIB 对使用 AT 解决方案的影响, 为旅游行业对 AT 解决方案的技术接受的理论发展和概念化做出贡献。本研究将介绍培训对 PwVIB 旅游行为的影响, 并为利益相关者提供有价值的信息。

对 128 名无身份者在评估了辅助设施后收集的问卷数据进行了探索性因素分析、确认性因素分析和结构方程模型分析, 然后进行了评估后访谈。所采用的应用程序名为 “BlindMuseumTourer”, 可在博物馆和医疗场所等旅游景点为 PwVIB 提供高精度的自主室内导航。

结果表明, 扩展模型的部分结果验证了性能预期和培训（新因素）在预测无障碍游客在旅游活动中使用自动视听设备的行为意向方面的重要性。这表明, 从业人员必须提供性能优越的技术解决方案, 并辅以专门的培训课程, 以提高参与度和满意度。

本研究通过增加一个新因素和替换两个调节变量, 为UTAUT 理论在无障碍游客旅游方面的应用做出了贡献。据我们所知, 在旅游文献中, 还没有类似的工作是研究 PwVIB 对 AT 的接受程度。此外, 在验证过程中还使用了一个新颖的室内导航应用程序, 并在希腊触觉博物馆展示了其有效性。

Las personas con discapacidad visual o ceguera (PwVIB) están excluidas en su mayoría de las actividades turísticas. A pesar del auge de las soluciones de tecnología de asistencia (TA) en el turismo, su aceptación sigue siendo baja debido a la dificultad de proporcionar la funcionalidad, eficacia y usabilidad adecuadas. Podría decirse que la formación orientada a la discapacidad puede afectar a las dos últimas y, por tanto, a la aceptación de una solución de TA. Este artículo pretende contribuir al desarrollo teórico y a la conceptualización de la aceptación de las soluciones de tecnología de apoyo en el turismo estudiando, en el contexto de la Teoría Unificada de la Aceptación y el Uso de la Tecnología (UTAUT), los efectos de la formación de las PwVIB en la utilización de las soluciones de tecnología de apoyo. El estudio presentará los efectos de la formación en el comportamiento turístico de las PwVIB y proporcionará información valiosa a las partes interesadas.

Los datos del cuestionario recogidos de 128 PwVIB tras la evaluación de una TA se sometieron a un Análisis Factorial Exploratorio y Confirmatorio y a un Modelado de Ecuaciones Estructurales, seguidos de entrevistas posteriores a la evaluación. La aplicación empleada, denominada BlindMuseumTourer, permite la navegación autónoma en interiores de alta precisión para PwVIB en lugares turísticos como museos y lugares de asistencia sanitaria.

Los resultados indican la satisfacción parcial del modelo ampliado validando la importancia de la expectativa de rendimiento y la formación en la predicción de la intención conductual de los turistas PwVIB por lo que sugieren a los profesionales que las sesiones especiales de formación son esenciales para el compromiso y la satisfacción de los usuarios.

Este estudio contribuye a la teoría UTAUT en el contexto del turismo para PwVIB añadiendo un nuevo factor y sustituyendo dos variables moderadoras. Hasta donde se sabe, no existe ningún trabajo similar que estudie la aceptación de la TA por parte de las PwVIB en la literatura sobre turismo. Además, en el proceso de validación se utilizó una novedosa aplicación de navegación en interiores que ha demostrado su eficacia en el Museo Táctico de Grecia.
