The purpose of this article is to examine the antecedents and consequences of organizational silence and employee silence to determine whether these two concepts should be distinguished rather than used interchangeably in research.

This study conducted a systematic literature review of 79 studies on organizational silence and 113 on employee silence, leading to three major findings.

First, this study shows that organizational silence is a collective phenomenon and employee silence occurs at the individual level; therefore, indicating they should be treated as two distinct concepts. Second, both types of silence are influenced by contextual factors (internal and external) and leadership. Third, organizational silence impacts both individual and organizational outcomes, whereas employee silence mainly affects an individual’s psychological health and performance.

This research clarifies the distinction between organizational silence and employee silence, offering guidance for researchers on how to approach these concepts. It also highlights the critical need to address workplace silence and the potential harm it may cause to both organizational and individual well-being if left unaddressed. Furthermore, this research supports organizational leaders and human resource developers in fostering a healthier work culture, improving performance and driving continuous improvement.

The purpose of this study is to emphasize the important role of performance-oriented human resource (HR) practices and gender equality perceptions in supervisors and chief executive officers (CEOs) for career development among women in management.

This study used a quantitative methodology to examine relationships among variables. The authors conducted a survey to investigate factors influencing the career development of women managers in professional settings, with a sample of 1,502 female managers in South Korea.

The relationship between performance-oriented HR practices and career development for women managers was supported. In addition, self-leadership significantly mediated the relationship between performance-oriented HR practices and career development. Finally, double moderator effects of gender equality perceptions of CEOs and supervisors on the relationship between performance-oriented HR practices and self-leadership were significant.

This study emphasizes that career development for women in South Korea depends on gender equality awareness and institutional reorganization for best practices at top management levels. Specifically, this study identified the essential role of performance-based HR practices to support self-leadership and career development in women managers. Furthermore, this study recognized gender equality perceptions of CEOs and supervisors as a critical factor in the successful career development of women managers.

Textual information about restaurants, such as online reviews and food categories, is essential for consumer purchase decisions. However, previous restaurant recommendation studies have failed to use textual information containing essential information for predicting consumer preferences effectively. This study aims to propose a novel restaurant recommendation model to effectively estimate the assessment behaviors of consumers for multiple restaurant attributes.

The authors collected 1,206,587 reviews from 25,369 consumers of 46,613 restaurants from Yelp.com. Using these data, the authors generated a consumer preference vector by combining consumer identity and online consumer reviews. Thereafter, the authors combined the restaurant identity and food categories to generate a restaurant information vector. Finally, the nonlinear interaction between the consumer preference and restaurant information vectors was learned by considering the restaurant attribute vector.

This study found that the proposed recommendation model exhibited excellent performance compared with state-of-the-art models, suggesting that combining various textual information on consumers and restaurants is a fundamental factor in determining consumer preference predictions.

To the best of the authors’ knowledge, this is the first study to develop a personalized restaurant recommendation model using textual information from real-world online restaurant platforms. This study also presents deep learning mechanisms that outperform the recommendation performance of state-of-the-art models. The results of this study can reduce the cost of exploring consumers and support effective purchasing decisions.

关于餐厅的文本信息, 如在线评论和食品分类, 对于消费者的购买决策产生至关重要。然而, 先前的餐厅推荐研究未能有效利这些文本信息去预测消费者喜好。本研究提出了一种新颖的餐厅推荐模型, 以有效估计消费者对多个餐厅属性的评估行为。

我们从 Yelp.com 收集了来自25,369名消费者对 46,613 家餐厅的 1,206,587 条评论。利用这些数据, 我们通过结合消费者身份和在线消费者评论生成了消费者偏好向量。然后, 我们结合了餐厅身份和食品分类来生成餐厅信息向量。最后, 考虑到餐厅属性向量, 本研究调查了消费者偏好和餐厅信息向量之间的非线性交互关系。

我们发现, 所提出的推荐模型相比于之前最先进的模型表现出更优秀的性能, 这表明结合消费者和餐厅的各种文本信息是预测消费者喜好的基本因素。

据我们所知, 这是第一项利用来自真实在线餐厅平台的文本信息开发个性化餐厅推荐模型的研究。本研究还提出了胜过最先进模型的深度学习机制。本研究的结果可以降低探索消费者行为的成本并支持有效的购买决策。

There is significant amount of literature tackling different issues related to the port industry. The present chapter focuses on a single business unit of seaports aiming at the documentation of works related to container terminals.

An effort to review, collect and present the majority of the works present in the last 30 years, between 1980 and 2010, has been made in order to picture the problems dealt and methods used by the authors in the specific research field. To facilitate the reader, studies have been grouped under five categories of addressed problems (productivity and competitiveness, yard and equipment utilization, equipment scheduling, berth planning, loading/unloading) and four modelling methodologies (mathematics and operations research, management and economics, simulation, stochastic modelling).

The analysis shows that most works focus on productivity and competitiveness issues followed by yard and equipment utilisation and equipment scheduling. In reference to the methodologies used managerial and economic approaches lead, followed by mathematics and operations research.

In reference to future research, two fields have been identified where there is scope of significant contribution by the academic community: container terminal security and container terminal supply chain integration.

The present chapter provides the framework for researchers in the field of port container terminals to picture the so far works in this research area and enables the identification of gaps at both research question and methodology level for further research.

This study aims to ascertain whether technological diversification (TD) enhances firm performance and explores the effect of patent portfolio balancing (PPB) on firm financial performance and the moderating role of research and development (R&D) intensity.

This study empirically investigates a panel dataset based on 296 information and communications technology (ICT) small and medium-sized enterprises (SMEs) over 5 years, using a fixed-effects panel regression with time-lagged and moderating effects. Data are collected from a government survey and a firm and patent database.

The relationship between PPB and return on assets (ROA) is negative, indicating that TD in SMEs adversely affects firm performance. R&D intensity positively moderates the relationship between PPB and ROA, implying that follow-up R&D after creating new patents could weaken the negative relationship between TD and firm performance. This moderating effect only occurs when R&D intensity is sufficiently high, suggesting that high R&D firms could be more successful at diversification.

As TD consumes many resources, managers should set the optimal level of diversification and recognise the need for follow-up R&D for successful diversification.

This study conceptualises a unique theoretical framework for the PPB of ICT SMEs, revealing the moderating role of R&D intensity in changing the negative influence of PPB on firm performance.

The purpose of this paper is to examine the efficacy of microbial elimination using different sanitizers in raw vegetables (cherry tomatoes, spring onions, Chinese chives, and chicory) and to analyze the efficacy of Escherichia coli O157:H7 reduction by type of sanitizer and vegetable.

To assess the sanitizing effects of microbial elimination by variety of vegetable, the samples were grouped into four different washing methods: control (no sanitizer), 100 ppm chlorine, 100 ppm electrolyzed water, and 200 ppm electrolyzed water after prewashing. Subsequently, quantitative microbiological experiments were conducted to assess aerobic mesophilic plate count (APC), coliform, E. coli, and Bacillus cereus, and sensory changes of the sanitized vegetables were tested. Thereafter, measurement of the sanitizing effects on bacterial reduction after inoculation with E. coli O157:H7 was conducted.

The microbial levels of four types of vegetables ranged from 3.37 to 5.24 log CFU/g for APC, 2.41 to 5.57 log CFU/g for E. coli, 0.25 to 5.40 log CFU/g for coliform, and 0.83 to 5.44 log CFU/g for B. cereus. After three types of sanitizing treatments, microbial reduction effects showed 0.94-1.84 log CFU/g for APC, 0.56-1.00 log CFU/g for E. coli, 0.18-1.26 log CFU/g for coliform, and 0.56-1.23 log CFU/g for B. cereus (p<0.05). In sensory evaluation, there were no significant differences in taste and flavor between with and without sanitizing treatments. Regarding bacterial reduction after inoculation with E. coli O157:H7, the microbial reduction on vegetables was shown to be in the range of 0.27-1.57 log CFU/g with 100 ppm sodium hypochlorite, 0.66-3.07 log CFU/g with 100 ppm electrolyzed water, and 0.79-2.55 log CFU/g with 200 ppm electrolyzed water. Chicory, cherry tomato, and spring onion showed significant reduction levels of E. coli O157:H7 after sanitation (p<0.05).

This study revealed that different sanitization methods are required for different types of vegetables. Electrolyzed water treatment (100 ppm) is a more effective and safe method of washing raw vegetables. Given that the main purpose of sanitizing fresh-cut produce is to maximally reduce microorganism levels, different methods of sanitizing fresh-cut produce with an adequate washing method should be used according to vegetable type.

This study aims to propose and validate a model for e-Learning success based on students’ experiences in the “new normal.” To achieve this goal, this study focused on answering three research questions: (1) What are the students’ experiential factors that impact e-Learning? (2) How do these experiential factors affect e-Learning success? (3) In what ways does a multimethod provide a comprehensive perspective and an in-depth understanding of students’ e-Learning experiences in the new normal?

This study applied a mixed-methods sequential approach using exploratory, confirmatory and complementary studies. First, this study undertook a text-mining exploratory analysis of the review data to extract e-Learning topics. Then, based on the Information Systems (IS) success model, this study identified an integrated framework drawn from the results of the text-mining analysis. Second, this study proposed an e-Learning, experience-based success model and corresponding hypotheses and conducted a confirmatory study with surveys to validate the model. Third, this study conducted in-depth interviews to better identify the phenomenon of interest.

The five factors extracted from the first stage are system quality, lecture content, teaching quality, online interaction and achievement. This study subsequently confirmed the significant relationships between the e-Learning success factors in the second stage based on the IS success model. Finally, a complementary study identified the importance of interactivity for e-Learning success in the new normal.

To the best of the authors’ knowledge, this paper is the first to develop an e-Learning success model using a comprehensive mixed-methods approach.

The purpose of this paper is to help understand consumer acceptance of online health information services by integrating the health belief model and extended valence framework.

A laboratory-based, experimental-scenarios research design is used to collect data, and the structural equation modeling technique is used to test the research model.

The model explains 47.6 percent of the variance in intentions to use online health information services. Trust appeared to have the strongest effect on acceptance. Perceived risk also had a significant impact on acceptance. Furthermore, health belief variables are confirmed as important factors for consumer acceptance. Self-efficacy was found to moderate the effect of perceived severity on acceptance.

This study helped identify the relative salience of the health belief model and extended valence framework in consumer acceptance of online health information services.

This study can help practitioners better understand the development of trust and the profiles of consumers who may browse their sites. When online health service providers promote their information to encourage potential online health information seekers, they should use countermeasures against risk perceptions.

This study attempted to extend the valence framework to the non-commercial service context. Moreover, health beliefs and the valence framework are two fundamental aspects that health information seekers consider when making decisions about online health services.

This paper employs the concept of supply chain orientation in container port management and empirically tests whether the measurement models proposed in some notable previous research have universal application. In addition, this study attempts to identify any significant causal relationships between port supply chain orientation and port performance from the view point of shipping companies. In the current study port supply chain orientation was found to have limited effect on customer satisfaction and port competitiveness, which might has been caused by some implemental and practical issues. However, the present study reveals the potential importance of port supply chain management by empirically demonstrating that “closer relationship with shipping lines” and “innovative value added service” could function as critical components for container ports/terminals to improve customer satisfaction and enhance their competitiveness.

The purpose of this study is to demonstrate the lighter (entertainment and esthetic experiences) and darker sides (educational and escapist experiences) of dark tourism experiences. This study also examines the effect of lighter and darker sides of dark tourism experiences on functional and emotional value.

To investigate how and where visitors experience lighter and darker sides of dark tourism, the authors conducted in-depth interviews from visitors to the Korean demilitarized zone (DMZ). To demonstrate consequences of lighter and darker sides of dark tourism experiences on functional and emotional value, the authors collected field survey data. Taken together, the authors used mixed methods with exploratory sequential design.

Interviewees vividly described their entertainment (crossing the suspension bridge) and esthetic experiences (seeing a family of crane birds from a short distance) in the Korean DMZ. They also described educational (understanding the background of the civil war) and escapist experiences (limiting daily entries made them feel like they were entering a special place or even a foreign country). Survey results showed that educational and esthetic experiences increased emotional value, while educational and escapist experiences enhanced functional value of a tour of the Korean DMZ.

Previous research operationalized lighter and darker sides of dark tourism based on characteristics of dark tourism sites. Specifically, darker and lighter aspects of dark tourism were determined, depending on whether such sites are directly related to human death or not. However, the current study draws on tourist experiences to operationalize lighter and darker sides of dark tourism. While previous research focused on the supply side, this study shifts focus to the demand side, thereby advancing knowledge in hybrid dark tourism experiences.

本研究旨在通过娱乐和审美体验（相对于教育和逃避现实的体验）展示黑暗旅游的光明（相对于黑暗）的一面。除此, 本研究以到访频率和到访目的作调节变量, 分别探讨上述四个类别的黑色旅游体验、功能性或情感性价值和访客满意度的关系。

为了深入探究上述四个类别的黑色旅游体验的性质, 我们与韩国非军事区的访客进行了深入的访谈。我们收集了田野问卷数据来测试上述四个类别的黑色旅游体验、价值观和满意度。运用测量不变性测试和多组分析试验了到访频率和到访目的之调节变量。

受访者在韩国非军事区生动地描述他们的娱乐（走过吊桥）和审美经历（近距离观赏一群鹤鸟）。他们还描述了教育（解释了韩战的背景）和逃避现实的经历（每日入场人数限制让访客觉得他们正在进入一个特别的地方甚至是国外）。问卷结果显示了教育和审美经历引致了情感价值, 教育和逃避现实经历则引致功能价值。

先前的研究根据黑色旅游地点的特点, 对黑色旅游的光明面和黑暗面进行了展示。具体来说, 根据这些地点是否与人类死亡直接相关, 确定了黑暗旅游的光明及黑暗的方面。然而, 本研究利用旅游体验来定义黑色旅游的光明面和黑暗面。虽然之前的研究侧重于旅游供应方面, 但本研究将重点转移到需求方面, 从而推进了混合黑色旅游体验的知识发展。

El propósito de este estudio es demostrar el encendedor (entretenimiento y estética) experiencias) y los lados más oscuros (experiencias educativas y escapistas) de las experiencias de turismo oscuro. Este El estudio también examina el efecto de los lados más claros y más oscuros de las experiencias de turismo oscuro en funcional y valor emocional.

Para investigar cómo y dónde los visitantes experimentan más claro y más oscuro lados del turismo oscuro, los autores realizaron entrevistas en profundidad a visitantes del desmilitarizado coreano zona desmilitarizada (DMZ). Demostrar las consecuencias de los lados más claros y más oscuros de las experiencias de turismo oscuro en valor funcional y emocional, los autores recopilaron datos de encuestas de campo. En conjunto, los autores utilizaron métodos mixtos con diseño secuencial exploratorio.

Los entrevistados describieron vívidamente su entretenimiento (cruzar el puente colgante) y Experiencias estéticas (ver una familia de pájaros grulla desde una corta distancia) en la DMZ coreana. Ellos también describió experiencias educativas (comprendiendo los antecedentes de la guerra civil) y escapistas (limitar las entradas diarias les hizo sentir como si estuvieran entrando en un lugar especial o incluso en un país extranjero). Los resultados de la encuesta mostraron que las experiencias educativas y estéticas aumentaron el valor emocional, mientras que Las experiencias educativas y escapistas mejoraron el valor funcional de un recorrido por la DMZ coreana.

Investigaciones anteriores operacionalizaron los lados más claros y más oscuros del turismo oscuro con base en Características de los sitios de turismo oscuro. Específicamente, los aspectos más oscuros y más claros del turismo oscuro fueron determinado, dependiendo de si tales sitios están directamente relacionados con la muerte humana o no. sin embargo, el El estudio actual se basa en las experiencias turísticas para operacionalizar los lados más claros y más oscuros del turismo oscuro. Si bien la investigación anterior se centró en el lado de la oferta, este estudio cambia el enfoque hacia el lado de la demanda, por lo que avanzar en el conocimiento de experiencias híbridas de turismo oscuro.
