The purpose of this study is to provide insights and guidance for practitioners in terms of ensuring rigorous ethical and moral conduct in artificial intelligence (AI) hiring and implementation.

The research employed two experimental designs and one pilot study to investigate the ethical and moral implications of different levels of AI implementation in the hospitality industry, the intersection of self-congruency and ethical considerations when AI replaces human service providers and the impact of psychological distance associated with AI on individuals' ethical and moral considerations. These research methods included surveys and experimental manipulations to gather and analyze relevant data.

Findings provide valuable insights into the ethical and moral dimensions of AI implementation, the influence of self-congruency on ethical considerations and the role of psychological distance in individuals’ ethical evaluations. They contribute to the development of guidelines and practices for the responsible and ethical implementation of AI in various industries, including the hospitality sector.

The study highlights the importance of exercising rigorous ethical-moral AI hiring and implementation practices to ensure AI principles and enforcement operations in the restaurant industry. It provides practitioners with useful insights into how AI-robotization can improve ethical and moral standards.

The study contributes to the literature by providing insights into the ethical and moral implications of AI service robots in the hospitality industry. Additionally, the study explores the relationship between psychological distance and acceptance of AI-intervened service, which has not been extensively studied in the literature.

The purpose of this study was to investigate restaurant employee behaviors and their likelihood of intervening when witnessing food safety threats.

A mixed method was used for this study with the focus group interview and survey questionnaire. A total of eight focus groups ranging in number of participants from to 6 to 12 were asked to respond to presented scenarios that depicted restaurant employees committing food safety risk behaviors and threats in the restaurant environment that would present food safety risks such as out-of-stock bathroom supplies, dirty tables in the restaurant dining area, employee personal hygiene issues and unclean production equipment. These participants were also asked to complete a draft of the survey that would later be edited and distributed to the sample population.

Results suggest that social norms and perceived severity of threats impact the likelihood that restaurant employees will intervene. Implications for academics and practitioners are discussed.

This study was special as it provides a synthetic viewpoint that considers how service organizations can work to do a better job of interviewing employees before starting their jobs about their beliefs and personal practices of food safety at home, their previous work in the restaurant industry and food safety culture that they may have worked in before, as well as increasing the communication in restaurants to build a food safety culture. These practices can help to lower risks to the public regarding food safety and can help to build relationship trust in the brands that we all love to indulge in when dining out.

This paper is an empirical attempt to verify the interplay between political change, fleet nationality, and the evolution of shipping networks. North Korea offers a good example of a socialist maritime country that has experienced much contrasting geopolitical contexts since 1990. A database of vessel movements between North Korean ports and other ports is analyzed. Main results show differences between North Korean and foreign fleets in terms of traffic (vessel size, age, berthing time) and geographical coverage. South Korean ports tend to play a new role in the reorganization of North Korean-related flows in Northeast Asia.

The purpose of this paper is to provide an overview of the evolution of service supply chain management from a behavioural operations perspective, pointing out future research directions for scholars.

This study searched five databases for relevant literature published between 2009 and 2018, selecting 64 papers for this review. The selected literature was categorised according to two dimensions: a service supply chain link perspective and a behavioural factor perspective. Comparative analysis was used to identify gaps in the literature, and five future research agendas were proposed.

In terms of the perspective of service supply chain link, extant literature primarily focuses on service supply and service co-ordination management, and less on service demand and integration management. In terms of the behavioural factor’s perspective, most focus on classic behaviour factors, with less attention paid to emerging behaviour factors. This paper thus proposes five research agendas: demand-oriented management and integrated supply chain-oriented behavioural research; broadening the understanding of the scope of behavioural operations; integrating the latest backgrounds and trends of service industry into the research; greater attention to behavioural operations in service sub-industries; and multimethod combination is encouraged to be used to dig into the interesting research problems.

This study constitutes the first systematic review of service supply chain research from a behavioural perspective. By categorising the literature into two dimensions, the state of existing research is evaluated with an eye towards future research avenues.

Based on DNase I and reduced graphene oxide (rGO)-magnetic silicon microspheres (MNPS), a highly sensitive and selective fluorescent probe for the detection of PD-L1 was developed.

Here °C we present a feasibility of biosensor to detection of PD-L1 in lung tumors plasma. In the absence of PD-L1°C the PD-L1 aptamer is absorbed on the surface of graphene oxide modified magnetic nanoparticles °8rGO-MNPS°9 and leading to effective fluorescence quenching. Upon adding PD-L1°C the aptamer sequences could be specifically recognized by PD-L1 and the aptamer/PD-L1 complex is formed°C resulting in the recovery of quenched fluorescence.

This sensor can detect PD-L1 with a linear range from 100 pg mL⁻¹ to 100 ng mL⁻¹, and a detection limit of 10 pg•m⁻¹ was achieved.

This method provides an easy and sensitive method for the detection of PD-L1 and will be beneficial to the early diagnosis and prognosis of tumors.

The purpose of this paper is to examine the influence of earnings persistence and earnings power on equity valuation.

The purposive sampling method was applied to determine the samples of selected 100 firms. This study employed secondary data obtained from the annual reports and financial statements of consumer goods firms listed on the Indonesian Stock Exchange for the period 2010–2014. The analysis technique used a multiple regression analysis.

The study result shows that, partially, earnings persistence and earnings power affect equity valuation by investors. Earnings persistence has a negative influence, whereas earnings power has a positive influence on equity valuation.

This study throws additional lights on equity valuation specific to consumer goods industries.

The study aims to explain the communicative basis of conflicts in which actors stand in opposition in defining a negotiated situation and to deepen knowledge of environmental conflict development, in particular on how frames are (re)shaped through discursive choices in interaction.

This study adopts an interactional approach to framing and 1) identifies the frames shaped and reshaped in four environmental debates and 2) analyzes how framing activities affect the course of the debates.

This study contributes to understanding 1) the interactive nature of conflicts; 2) how the reception and interpretation of issue framing depends on the surrounding identity and characterization framing and 3) how framing activities, like identity work, emotional alignment and reframing, can affect the course of environmental debates toward polarizing or bridging.

On a methodological level, this study contributes to communication research by applying methodologies for investigating framing processes on a micro-level. This study investigates interactional framing, considering the perspectives of frame strategists engaging in issue arenas. The study provides an in-depth discourse analysis of the debates but lacks an overview on the entire issue arena regarding this conflict.

Skilled actors span boundaries by articulating issue frames that accommodate opponents' concerns and values while demonstrating the added value of the new frame, adjusting identity work in favor of relations with opponents. Furthermore, calibrating emotional intensity offers opportunities to mobilize support.

This research investigates which communicative competences are essential to act adequately in environmental conflicts, given their intractable nature, and suggests opportunities for cocreation by making discursive choices. This approach helps to uncover the micro-processes that escalate and de-escalate a conflict.

The literature on ‘mixed’ families (in which members are socially viewed as ‘different’ due to their varying ethnicities and/or nationalities) identifies several stakes of mixedness. One of them arises from childbirth, after which parents need to give name(s) to their offspring. How does the parent–child dyad understand the giving of names in their mixed family? What does naming children unveil regarding interpersonal interactions and the value of children within this social unit? The chapter delves into these questions through a case study of forenaming children in Filipino-Belgian families in Belgium. Interview data analysis reveals two modes of forenaming in these families: individualisation through single forenames and reinforcement of collective affiliation through compound forenames. Through the analytical framework of social relatedness, this chapter uncovers the way the act of naming a child bridges families based on biological and social ties, generations, and parents' nations of belonging in their transnational spaces. The complex process of naming reflects the power dynamics not only within the parental couple but also within the wider set of social relations. Although the use of forename(s) in everyday life and in legal terms differ, the value of children in the mixed families studied lies in their symbolic role as social bridges linking generations and non-biological relationships, the then and now, and the here and there.

The paper aims to identify and analyze passengers’ riding paths for providing better operational support for digital transformation in megacity metro systems.

The authors develop a method to leverage certain passengers’ deterministic riding paths to corroborate other passengers’ uncertain paths. Using Automatic Fare Collection data and train schedules, a witness model is built to recover the actual riding paths for passengers whose paths are unknown otherwise. The identification and analysis of passenger riding paths between three different types of origin–destination) pairs reveal the complexity of passenger path choice.

The results show that passenger path choice modeling is usually characterized by complexity, experience and partial blindness. Some passengers choose paths that are not optimal due to their experience and limited access to overall metro system information. These passengers could be the subject of improved path guidance in light of riding efficiency improved through digital transformation.

This research contributes to the improvement of metro management and operations by leveraging ongoing digital transformation in megacity metro systems. Based on the riding paths and trip chains of a large number of individual passengers identified by the proposed method, metro operation management could prevent risks in areas with concentrated passenger flow in advance, optimally adjust train schedules on a daily basis and deliver real-time riding guidance station by station, which would greatly improve megacity metro systems’ service safety, quality and operational efficacy over time.

The purpose of this paper is to observe whether the entrenchment of managers can affect firms’ dividend disbursement decisions and investor sentiment in the Tunisia context.

The sample includes all non-financial listed stocks in the Tunisia stock exchange during the years 2004–2017. Moreover, the entrenchment of managers is measured by five proxy explained the managers rooting from all listed firms. The propensity to pay dividends is measured by the dividend yield.

The findings yield qualitatively consistent with the previous research. After controlling for the effect of a manager’s behavior and different entrenchment phase, the result shows that entrepreneurial the firm’s decision to pay dividends could be influenced by the managers’ entrenchment.

The result is limited at the level of the non-financial companies listed in the BVMT, but in future studies, the investigation with other countries can be compared.

Moreover, investors in Tunisia show their preference for a dividend to self-control and satisfaction and increase their profit, especially in an abnormal economic situation explained by the Tunisian political crisis.

The originality of this paper is to investigate both the important role of the entrenchment and cycle life of the manager on the decision to distribute dividends and the investor sentiment. Moreover, the author’s problem may be a reference for future investigation talking about the managers’ psychology like opportunism.
