The purpose of this paper is to provide a comprehensive analysis of dynamic pricing by Airbnb hosts.
Abstract
Purpose
The purpose of this paper is to provide a comprehensive analysis of dynamic pricing by Airbnb hosts.
Design/methodology/approach
This study uses attribute and sales information from 39,837 Airbnb listings and hotel data from 1,025 hotels across five markets to test different hypotheses which explore the extent to which Airbnb hosts use dynamic pricing and how their pricing strategies compare to those of hotels.
Findings
Airbnb is a unique and complex platform in terms of dynamic pricing where hosts make limited use of dynamic pricing strategies, especially as compared to hotels. Notwithstanding their limited use, hosts who own listings in high-demand leisure markets, manage entire places, manage more listings and have more experience vary prices the most.
Practical implications
This study identified a great need for Airbnb to encourage dynamic pricing among its hosts, but also warned of the potential perils of dynamic pricing in the sharing economy context. The findings also demonstrated challenges for hotel managers interested in actionable information related to Airbnb as a competitor.
Originality/value
This is the first Airbnb study to use a comprehensive set of data over a continuous period in multiple markets to look at a number of listing and host factors and determine their relation with dynamic pricing strategies.

Abstract
Purpose
The purpose of this paper is to reduce the crop losses at two ends and both sides of a plate in the rolling process, to produce a rectangular plan view pattern plate and to enhance the total product yield of the plates.
Design/methodology/approach
Based on sample data and the unchangeable principle of the slab volume in the rolling process, the predictive MAS control models were set‐up. They are width broad MAS predictive model, width broad MAS control model, gaugemeter automatic gauge control (GM‐AGC) model, and plates tracking model. After the models were tuned, the rolling test was implemented at LinFen Iron & Steel Co., Ltd.
Findings
It is found that by accurately predictive online modeling of MAS methods, the plan view pattern control can be applied in plate mills.
Research limitations/implications
As the rolling process is in high temperature, the plan view pattern is difficult to be detected. Normally, the real‐time abnormity distortion cannot be obtained.
Practical implications
The test results showed that the crop losses are reduced and the product yield is greatly increased.
Originality/value
This paper presents an accurately predictive online modeling of MAS method.

This paper aims to study the synergistic lubrication effects of Sn–Ag–Cu and MXene–Ti3C2 to improve the tribological properties of M50 bearing steel with microporous channels.
Abstract
Purpose
This paper aims to study the synergistic lubrication effects of Sn–Ag–Cu and MXene–Ti3C2 to improve the tribological properties of M50 bearing steel with microporous channels.
Design/methodology/approach
M50 matrix self-lubricating composites (MMSC) were designed and prepared by filling Sn–Ag–Cu and MXene–Ti3C2 in the microporous channels of M50 bearing steel. The tribology performance testing of as-prepared samples was executed with a multifunction tribometer. The optimum hole size and lubricant content, as well as self-lubricating mechanism of MMSC, were studied.
Findings
The tribological properties of MMSC are strongly dependent on the synergistic lubrication effect of MXene–Ti3C2 and Sn–Ag–Cu. When the hole size of microchannel is 1 mm and the content of MXene–Ti3C2 in mixed lubricant is 4 wt.%, MMSC shows the lowest friction coefficient and wear rate. The Sn–Ag–Cu and MXene–Ti3C2 are extruded from the microporous channels and spread to the friction interface, and a relatively complete lubricating film is formed at the friction interface. Meanwhile, the synergistic lubrication of Sn–Ag–Cu and MXene–Ti3C2 can improve the stability of the lubricating film, thus the excellent tribological property of MMSC is obtained.
Originality/value
The results help in deep understanding of the synergistic lubrication effects of Sn–Ag–Cu and MXene–Ti3C2 on the tribological properties of M50 bearing steel. This work also provides a useful reference for the tribological design of mechanical components by combining surface texture with solid lubrication.

Abstract
Purpose
The purpose of this paper is to determine the value of I‐Ching (also called Book of Changes), the ancient Chinese book of wisdom, which has been used for thousands of years to help people make decisions in daily life. Recently, eastern and western scholars have begun discussing how to apply the wisdom of I‐Ching to the field of business administration, particularly decision‐making practices.
Design/methodology/approach
A content analysis method was adopted to uncover possible modern management decision‐making constructs. The single words approach did not find frequently appearing words that integrated decision‐making constructs in the context of I‐Ching. Further uncovering I‐Ching's administrative decision‐making approach, the managerial decision‐making model of I‐Ching is explained, including the premises, the decision contingencies, and the decision process.
Findings
By using an academic comparative analysis method, as it applies to managerial decision making, I‐Ching's early management decision‐making model is subsequently compared with western management decision models, which include rational decision making, bounded‐rationality decision making, intuitive decision making, implicit favorite decision making, and garbage‐can decision making.
Research limitations/implications
The majority of scholars that study I‐Ching focus on “practice divination” research, paying attention to the interpretation or critique of the text only. Unfortunately, related literature based upon a social science research foundation is limited.
Originality/value
The value of I‐Ching was determined to lie in allowing flexibility in the decision‐making process.

Abstract
Purpose
The purpose of this paper is to show that, since China's accession to the WTO in 2001, standards have emerged as an effective means to protect and promote domestic industries, especially in the ICT sector. China has made several attempts to set its own technological standards – different from international standards – within its own territory and world‐wide. This paper seeks to examine two cases of China's attempts to set its own standards in the ICT sector. By comparing similarities and differences in these cases, it aims to identify motivations and strategies of China's standards‐setting attempts in the ICT sector.
Design/methodology/approach
The paper examines the cases of wireless LAN security (WAPI) and 3G mobile communications (TD‐SCDMA). It draws on a set of concepts from the study of national technological innovation systems: techno‐nationalism and techno‐globalism. Data were collected from media and standards‐related institutions.
Findings
Despite similarities, each case has a distinguished orientation in terms of techno‐nationalism and techno‐globalism: WAPI is aligned with techno‐nationalism and TD‐SCDMA with techno‐globalism.
Research limitations/implications
China's recent attempts regarding its own standards in the ICT sector are not one‐off occasions, but China's standards policy towards international standards will continue. This research will be a foundation for further inquiry in this increasingly important area of study. A longitudinal follow‐up study tracking the development of each standard over time is required.
Originality/value
Despite the significance of these standard‐setting attempts for China's trade, technology policy and economic development, on the one hand, and for the world economy, on the other hand, there has been little research in this area. The paper offers an enhanced understanding of China's standards policy.

Abstract
Purpose
Disaster management information systems (DMISs) have been proposed in different parts of the world for effective response to a disaster. The purpose of this paper is to: compare design approaches of these DMISs; examine similarities in the design of databases and communication infrastructure; and draw conclusions. Based on the examination of the studies, future opportunities have been identified and discussed.
Design/methodology/approach
The studies in the available literature on the designs of automated DMISs have been reviewed in the presented paper to identify similarities in design premise, conceptual design and design considerations.
Findings
The examination of the available studies indicates that the research on DMIS has increased significantly in different countries of the world since 2004. Data of baseline information and available resources are required by most of the presented studies, as these data are necessary for effective response to a disaster. The communication infrastructures suggested include local area network, wide area network and satellite communication for better coordination between the responders and different relief agencies at different locations. The connectivity to these networks is possible through Ethernet, Wi-Fi, general packet radio service or satellite.
Research limitations/implications
Although the research on DMIS has increased significantly over the last one decade, the studies are still few in numbers. Similarly, only few of the proposed systems have been developed and tested during a real disaster.
Practical implications
The presented review of available studies provides a holistic view of the proposed DMISs which could be useful to the disaster management authorities.
Originality/value
The paper provides valuable information on the differences in the proposed DMISs. This can help in identifying the gaps for future improvements for increased effectiveness of a DMIS. The future opportunities have also been identified in the presented paper and are discussed.

Abstract
Purpose
This study aims to assess the pitting resistance of austenitic stainless steel welded joints fusion zone (FZ) with high density of inclusions before and after surface treatment, including potentiostatic pulse technique (PPT) and pickling.
Design/methodology/approach
The potentiodynamic polarization tests and critical pitting temperature tests were carried out for estimating pitting resistance. The PPT and pickling were performed as surface treatment. Scanning electron microscope (SEM) and energy dispersive spectrometer were used for characterize the microstructure and elemental distribution. Electron back-scattered diffraction (EBSD) was used to assess the portion of phases and morphology of grains.
Findings
The weld metal exhibits a higher degree of alloying compared to the base metal, and it contains d-phase and sulfur-containing inclusions. Sulfur-containing inclusions serve as initiation sites for pitting, and they diminish the pitting resistance of weld metal. Both PPT and pickling can remove sulfur-containing inclusions, but PPT causes localized dissolution of the weld metal matrix around the inclusions, while pickling does not. Because of the high density of inclusions, certain pits initiated by PPT are significantly deeper, which makes the formation of stable pitting easier. Because of the high density of inclusions, certain pits initiated by the PPT are deeper. This characteristic facilitates the progression of these initial defects into fully developed, stable pits.
Originality/value
Analysis of pitting initiation in shielded metal arc welding FZ with PPT and ex situ SEM tracking observation. Explanation of why the PPT surface treatment is not able to enhance the pitting resistance of stainless steel with a high inclusion density.

Abstract
Purpose
The purpose of this paper is to solve the problem of a three-dimensional computational analysis for an elliptic-shaped cavity in a pipe under constant temperature.
Design/methodology/approach
The three-dimensional computational solution of governing equations was performed by using finite volume method with different temperature difference.
Findings
The parafin wax was chosen as a phase change material (PCM), and melting fraction, streamlines and isotherms are formed for different time step. It is found that position B give better results than that of position A, and temperature difference effects the duration of melting of PCM.
Originality/value
The three-dimensional analysis of melting in an ellipsoidal pipe with inner pipe with higher temperature is the main originality of this work.
