Abstract

Purpose

The purpose of this study is to examine the intricate dynamics within the hospitality service sector, which predominantly employs low-wage and low-skilled workers. These employees frequently encounter challenges related to breaches in their psychological contracts. Despite their critical role in customer service, their experiences are often overlooked in organizational inclusion research. We investigate the relationship between employees’ perceptions of organizational inclusion and their assessments of organizational ethical virtues (OEVs), considering the potential moderating effect of psychological contract breach. Furthermore, it explores how these factors influence customer- and organizationdirected organizational citizenship behaviors (OCBs).

Design/methodology/approach

Our research design incorporates a two-stage moderated-mediation model to test our proposed hypotheses empirically. A two-source sample of 451 European hotel managers and employees extends the inquiry with the proposed model. Structural Equation Modeling (SEM) was employed to analyze the proposed relationships.

Findings

Findings reveal that organization inclusion is positively associated with OEV and employee-perceived OEV mediates an indirect link between organization inclusion on customer-oriented OCB. Moreover, psychological contract breach (P CB) attenuates the association between organization inclusion and OEV at the first stage and OEV, and OCB at the second stage.

Originality/value

The findings robustly corroborate our proposed model. The study findings culminate in a discussion accentuating the extensive implications of our findings for both research and practicality within the hospitality sector. Anchored in empirical revelations, we delineate avenues for future exploration in this pivotal domain.

Abstract

Purpose

The purpose of this paper is to present a new method and model for determining the optimal decision-making for the pricing strategy to the Fuji apple in Shaanxi of Chain which is representing fresh agricultural products under the e-commerce environment.

Design/methodology/approach

Considering the rapid development of information technology as well as internet that actually motivate the e-commerce, Fuji apple is a distinctive product in China’s Shaanxi; its sales channels have extended to online sales under the wave of e-commerce. Internet trading platforms make it possible to trade online in real time between suppliers and customers who live in different geographical areas. In this paper, the authors study how to price online to maximize the total revenue. The challenge is to optimally price two different qualities of apple. Based on the consumer surplus theory, the authors use the method that builds the function of the relationship between the proportion of consumers purchasing different qualities of products and price.

Findings

This paper presents a generalized model to determine the optimal pricing that maximizes the total revenue of a fruit grower over a finite planning horizon. The authors divided discount into two intervals and discussed the optimal discounting and pricing at both intervals. Then they determined the optimal pricing strategy for Fuji apple in Shaanxi of Chain under the e-commerce environment.

Originality/value

This paper makes up for the lack of existing studies of pricing under the e-commerce environment. A new method and approach to the traditional pricing strategy is established and applied to a management decision-making problem with Chinese characteristics in reality.

Abstract

Purpose

This paper aims to investigate the relationship between emotional labor and workplace violence based on the social exchange theory. Drawing on the social exchange theory, this paper aims to investigate the relationship between emotional labor and workplace violence. Specifically, the authors take a relational approach by introducing positive patient treatment as the mediator. The moderating role of organizational support in the relationship between emotional labor and workplace violence is also considered.

Design/methodology/approach

The data of this study encompasses 536 nurses from 10 university hospitals in Turkey. Hierarchical multiple regression analysis was conducted to test the proposed model.

Findings

The findings of this study support the negative effect of emotional labor on workplace violence and the mediating effect of patient-positive treatment. Moreover, when organizational support is low, the relationship between emotional labor and workplace violence is strong. In contrast, the effect is weak when organizational support is high.

Practical implications

The findings of this study suggest that health-care administrators should offer more training to nurses to help them manage their emotions while interacting with their patients. This leads to positive interpersonal relationships, which, in turn, lowers workplace violence. Moreover, health-care administrators should pay more attention to the buffering role of perceived organizational support for those subordinates with low emotional labor and higher workplace violence.

Originality/value

The study provides new insights into emotional labor’s influence on workplace violence and the moderating role of organizational support in the link between emotional labor and workplace violence. The paper also offers practical assistance to nurses in the health-care industry interested in building positive patient treatment and trust with their patients and minimizing workplace violence.

Abstract

Man has been seeking an ideal existence for a very long time. In this existence, justice, love, and peace are no longer words, but actual experiences. How ever, with the American preemptive invasion and occupation of Afghanistan and Iraq and the subsequent prisoner abuse, such an existence seems to be farther and farther away from reality. The purpose of this work is to stop this dangerous trend by promoting justice, love, and peace through a change of the paradigm that is inconsistent with justice, love, and peace. The strong paradigm that created the strong nation like the U.S. and the strong man like George W. Bush have been the culprit, rather than the contributor, of the above three universal ideals. Thus, rather than justice, love, and peace, the strong paradigm resulted in in justice, hatred, and violence. In order to remove these three and related evils, what the world needs in the beginning of the third millenium is the weak paradigm. Through the acceptance of the latter paradigm, the golden mean or middle paradigm can be formulated, which is a synergy of the weak and the strong paradigm. In order to understand properly the meaning of these paradigms, however, some digression appears necessary.

Abstract

Purpose

The purpose of this study is to prepare a state-of-the-art review on advanced ceramic materials including their fabrication techniques, characteristics, applications and wettability.

Design/methodology/approach

This review paper presents the various types of advanced ceramic materials according to their compounding elements, fabrication techniques of advanced ceramic powders as well as their consolidation, their characteristics, applications and wetting properties. Hydrophobic/hydrophilic properties of advanced ceramic materials are described in the paper with their state-of-the-art application areas. Optical properties of fine ceramics with their intrinsic characteristics are also presented within. Special focus is given to the brief description of application-based manipulation of wetting properties of advanced ceramics in the paper.

Findings

The study of wetting/hydrophobicity/hydrophilicity of ceramic materials is important by which it can be further modified to achieve the required applications. It also makes some sense that the material should be tested for its wetting properties when it is going to be used in some important applications like biomedical and dental. Also, these advanced ceramics are now often used in the fabrication of filters and membranes to purify liquid/water so the study of wetting characteristics of these materials becomes essential. The optical properties of advanced ceramics are equally making them suitable for many state-of-the-art applications. Dental, medical, imaging and electronics are the few sectors that use advanced ceramics for their optical properties.

Originality/value

This review paper includes various advanced ceramic materials according to their compounding elements, different fabrication techniques of powders and their consolidation, their characteristics, various application area and hydrophobic/hydrophilic properties.

Abstract

Purpose

The purpose of this study to investigate acetaminophen (ACT) degradation efficiencies by using ozone/persulfate oxidation process in a batch reactor. In addition, the effects of various parameters on the ACT removal efficiency toward pathway inference of ACT degradation were investigated.

Design/methodology/approach

The experiments were in the 2 L glass vessels. Ozone gas with flow rate at 70 L.h−1 was produced by ozone generator. After the adjustment of the pH, various dosages of persulfate (1, 3, 5, 7 and 9 mmol.L−1) were then added to the 500 mL ACT-containing solution with 150 mg.L−1 of concentration. Afterward, ozone gas was diffused in glass vessels. The solution after reaction flowed into the storage tank for the detection. The investigated parameters included pH and the amount of ozone and persulfate addition. For comparison of the ACT degradation efficiency, ozone/persulfate, ozone and persulfate oxidation in reactor was carried out. The ACT concentration using a HPLC system equipped with 2998 PDA detector was determined at an absorbance of 242 nm.

Findings

ACT degradation percentage by using ozone or persulfate in the process were at 63.7% and 22.3%, respectively, whereas O3/persulfate oxidation process achieved degradation percentage at 91.4% in 30 min. Degradation efficiency of ACT was affected by different parameter like pH and addition of ozone or persulfate, and highest degradation obtained when pH and concentrations of persulfate and ozone was 10 and 3 mmol.L−1 and 60 mg.L−1, respectively. O3, OH and SO4− were evidenced to be the radicals for degradation of ACT through direct and indirect oxidation. Gas chromatography–mass spectrometer analysis showed intermediates including N-(3,4-dihydroxyphenyl) formamide, hydroquinone, benzoic acid, 4-methylbenzene-1,2-diol, 4-aminophenol.

Practical implications

This study provided a simple and effective way for degradation of activated ACT as emerging contaminants from aqueous solution. This way was conducted to protect environment from one of the most important and abundant pharmaceutical and personal care product in aquatic environments.

Originality/value

There are two main innovations. One is that the novel process is performed successfully for pharmaceutical degradation. The other is that the optimized conditions are obtained. In addition, the effects of various parameters on the ACT removal efficiency toward pathway inference of ACT degradation were investigated.

Abstract

Purpose

Friction and wear are very important factors in predicting the performance of journal bearings, particularly under heavy load in start-up processes. However, there are few relevant studies on the numerical model. This study aims to establish a transient-mixed lubrication model to predict the performance of journal bearings, focusing on the friction and wear behavior under heavy load during start-up.

Design/methodology/approach

The average Reynold equation, three-dimensional energy equation, shear stress model for friction and Archard model for wear are coupled in the transient model by finite difference method. The linear wear simulation method is bought out to reduce the update times and the calculation time.

Findings

The different start-up accelerations and linear wear times set are compared and discussed, which indicates a reasonable start-up acceleration is necessary for journal bearings under heavy load during start-up, and setting linear wear times is an effective method to reduce the simulation time significantly. Furthermore, the wear profile in the start-up process spreads in both the clearance and circumferential directions, but mainly in the clearance direction, which increases the minimum film thickness and affects the friction performance.

Originality/value

This study is of great significance for the numerical prediction of the transient performance of journal bearings during start-up considering friction and wear.

Abstract

L'objet de cet article est de ramener les regards sur le fait touristique et sur les circonstances qui l'entourent. Celles‐ci sont très diverses. Il en est qui intéressent l'histoire diplomatique des Etats (telle la tension entre le Gouvernement français et les vallées d'Andorre dans l'été 1953, agissant négativement sur la fréquentation touristique estivale de ce coin des Pyrénées). D'autres sont en relation avec des faits d'actualité politique (la crise de Trieste en novembre 1953 a rempli les hôtels de Viareggio de touristes américains). Une mesure administrative (l'avancement des dates de vacances scolaires en France de 15 jours en 1953) se répercute sur le chiffre d'affaires des hôteliers bretons. Le progrès technique est partout décisif: l'ouverture d'une route pour aller, en Suisse, de Viège à Saas‐Fee change radicalement l'équation touristique de cette station. Quelque fois le tourisme repousse le tourisme: la création de services touristes aériens entre Paris et la Scandinavie porte tort aux services de première classe et conduit la compagnie aérienne à les rétablir (octobre 1953).

Abstract

Les stations de tourisme sont fréquentées par des clientèles appartenant à des milieux sociaux bien différents. Il y aurait plusieurs moyens pour s'en rendre compte. Il suffirait par exemple de faire une enquête dans la localité en pleine saison en s'informant de la profession des hôtes, de ce qu'ils veulent dépenser, du niveau de leur revenu. On pourrait relever les marques et la puissance des automobiles, la possession de «signes distinctifs» de richesse, etc… On pourrait encore faire une enquête directe auprès de certains commerces: salons de thé, dancings, casinos, coiffeurs pour dames, moniteurs de ski ou de danse, etc.
