Abstract

Purpose

Using the decision tree model, this study aims to understand the online travelers booking behaviors on Expedia.com, by examining influential determinants of online hotel booking, especially for longer-stay travelers. The geographical distance is also considered in understanding the booking behaviors trisecting travel destinations (i.e. Americas, Europe and Asia).

Design/methodology/approach

The data were obtained from American Statistical Association DataFest and Expedia.com. Based on the US travelers who made hotel reservation on the website, the study used a machine learning algorithm, decision tree, to analyze the influential determinants on hotel booking considering the geographical distance between origin and destination.

Findings

The results of the findings demonstrate that the choice of package product is the prioritized determinant for longer-stay hotel guests. Several similarities and differences were found from the significant determinants of the decision tree, in accordance with the geographic distance among the Americas, Europe and Asia.

Research limitations/implications

This paper presents the extension to an existing machine learning environment, and especially to the decision tree model. The findings are anticipated to expand the understanding of online hotel booking and apprehend the influential determinants toward consumers’ decision-making process regarding the relationship between geographical distance and traveler’s hotel staying duration.

Originality/value

This research brings a meaningful understanding of the hospitality and tourism industry, especially to the realm of machine learning adapted to an online booking website. It provides a unique approach to comprehend and forecast consumer behavior with data mining.

Abstract

Purpose

The past five years have seen a growth in studies of police body-worn cameras (BWCs). A large share of the research focused on individual officer attitudes toward these new law enforcement tools. The scholarship, however, focused almost exclusively on their positive and negative perceptions of body cameras or correlations between those attitudes and general officer characteristics. This study examined whether the influence of negative or “concerning” policing attitudes toward body cameras is mediated by other variables, such as officer outlooks toward law enforcement, officers' perceptions of citizen cooperation or their opinions of the public.

Design/methodology/approach

An online survey was distributed to a convenience sample of police offices from two Northeastern police agencies.

Findings

Findings indicate that the relationship between experience and concerning perceptions of body cameras is mediated by distrust in citizens and perceived civilian cooperation. Further, an office's outlooks regarding aggressive law enforcement tactics do not have a direct effect on concerning perceptions of body cameras, nor do they serve as a mediator between years of experience and concerning perceptions of body cameras.

Originality/value

Findings uncover the nuance and complexity of studying and understanding police officer outlooks and perceptions of BWCs. Future experimental designs should include general outlook measures.

Abstract

Purpose

This experimental study aims to examine the effectiveness of cause-related marketing messages that incorporate both text and visuals, as compared to messages comprised solely of text, on the attitudes and behavioral intentions of restaurant customers, and to see if the impact varies across four categories of social causes (health, animal welfare, human services and the environment).

Design/methodology/approach

This experimental study uses a 2 (type of message) × 4 (cause category) between-subjects design.

Findings

Restaurant messages that combine text and visuals are more effective than restaurant messages with only text in engendering positive attitudinal and behavioral responses. This paper also found interaction effects between advertisement type and cause category on individuals’ responses (i.e. attitudes and behavioral intentions).

Practical implications

The messaging strategies suggested by this research will allow the restaurant industry to capitalize on the value of cause-related marketing initiatives.

Originality/value

This research contributes to the hospitality literature by expanding the realm of research on effective cause-related marketing initiatives.

Abstract

Purpose

The purpose of this study was to identify the relationship between customer values, satisfaction and loyalty in the context of Airbnb.

Design/methodology/approach

The survey questionnaires were developed based upon review of previous studies. The samples were collected from US- based Airbnb users. The data were analyzed using structural equation modeling.

Findings

The result of this study indicates that first, Airbnb users’ hedonic value has a positive impact on satisfaction and loyalty, while utilitarian value influences only on satisfaction. Second, this study also shows that product involvement plays as a moderating role in the paths between hedonic value and customer satisfaction.

Research limitations/implications

Study findings may help researchers understand the roles of hedonic and utilitarian values and their impacts on satisfaction and loyalty in the context of Airbnb. This study also contributes to Airbnb marketers in fulfilling users’ expectations about the company.

Originality/value

This research contributes to the hospitality literature by expanding the realm of research on Airbnb, which is a unique company applying the sharing economy concept in the lodging industry.

Abstract

Purpose

This study aims to examine the brand tourism effect observed in luxury hotels. The study assumed that when loyal customers of luxury hotels perceive two different types of non-loyal customers, loyal customers’ perceptions might influence their behavioral intention. In addition, two emotions (i.e. anger and pride) might mediate the relationship between perceptions and behavioral intention.

Design/methodology/approach

This study used a scenario-based experimental design. Data from 1,013 responses were analyzed using partial least squares-structural equation modeling.

Findings

The study reveals that when loyal customers view brand tourists, infringement has a positive influence on switching intention, and likability positively effects brand loyalty. This study indicated that loyal customers perceive brand immigrants negatively, whereas brand tourists are comparably positively perceived by loyal customers. Only pride mediates these two relationships, respectively.

Originality/value

The study confirmed the brand tourism effect in luxury hotels by indicating a clearer relation between perception, emotion and behavioral intention. The theoretical implications could suggest insightful guidelines for future studies regarding loyalty in luxury hotels.

Abstract

Urban sociological research posits a strong correlation between social isolation and the growth in illicit activities of street culture, namely the drug trade and violent gang activities. However, in this article we offer an explanation for why, even in the absence of extreme poverty and social isolation from mainstream institutions, youths in Cambridge, Massachusetts feel vulnerable to illicit street cultural activities. We also offer an explanation for why these youths perceive the effects of social dislocation to be similar to that experienced by youths from larger central cities. As we will elaborate below, some students in Cambridge are affected by illicit street cultural activities because: (1) social dislocation is a relative phenomenon and not merely an absolute phenomenon as described by William J. Wilson; (2) there is a social dislocation spill‐over effect from larger central cities that intensifies or amplifies the experiences of youths in the relatively poorer neighborhoods of Cambridge; (3) and some youths, from stable working‐class or wealthier neighborhoods in Cambridge, view involvement in the illicit activities of street culture as a reputable means of gaining peer respect through status group affiliation.

Abstract

Purpose

In the tourism industry, unmanned aerial vehicles (UAVs) can perform monitoring and patrol missions to protect assets and tourists at attractions such as coastal areas, canyons, national parks, etc. Such use of UAVs can improve safety and security of tourism attraction and facilitate tourism industry. However, there is a key issue regarding economic investment and efficient operation for actual system implementation. The purpose of this paper is to provide a guideline for supporting economic investment and the efficient operation of UAV system in the tourism industry.

Design/methodology/approach

Ideas and methodologies have been proposed to overcome the fundamental limitations of commercial UAVs. A mathematical optimization model is developed to determine the optimal number of UAVs to be purchased, and its operation schedules simultaneously.

Findings

Using proposed concept and methodology, UAVs can support long duration of missions. Economic system design as well as the operation schedule is derived with the hypothesis data in Kkot-Ji beach in Korea. The proposed methodology and approach is expected to have huge potential at many tourism attractions to achieve the safety and security of tourists.

Practical implications

The result of this study can facilitate practical use of UAVs in the tourism industry. Furthermore, it is applicable in many industries that need UAV systems such as national defence, agriculture, disaster management, etc.

Originality/value

The proposed study suggests a solution to handle fundamental weakness of UAVs and support long duration of missions. In addition, this study incorporates economic system design issue and operation issue simultaneously.

Abstract

Purpose

This study investigates the pricing and inventory control decisions of a company that owns a coffeehouse chain providing drip coffee and a coffee manufacturing factory producing ready-to-drink (RTD) coffee. To determine a way to maximize profit, optimal pricing and inventory control strategies are studied for both the RTD coffee as well as the coffeehouse chain network.

Design/methodology/approach

It is assumed that the company sells only drip coffee through its coffeehouse chain and would like to launch RTD coffee via other channels such as convenience stores, supermarkets and so on to maximize its total profit. A mathematical model–based optimization is adopted to address the decision-making for the given problem situation, where the demand for both drip and RTD coffee are dependent on the values of decision variables. To solve the proposed mathematical model, particle swarm optimization (PSO) is applied due to nonlinearity of the developed model.

Findings

It is confirmed that a company can earn more profit by launching RTD coffee, even though the profit from drip coffee would reduce. In addition, the scenario analysis shows that by launching RTD coffee under various conditions, the total profits would also improve.

Originality/value

The value of this study is the proposed basic framework for the industry. In addition to the modeling framework and cost structure, realistic cost figures and technical details can be considered when applying the model to a practical setting.

Abstract

Purpose

This paper aims to propose an operation policy of multi-capacity room service robots traveling within a hotel. As multi-capacity robots can serve many requests in a single trip, improved operation policy can reduce the investment cost of robots.

Design/methodology/approach

Using a mathematical model-based optimization technique, an optimal set of robots with minimum installation cost is derived while serving the entire room service demands. Through testing a variety of scenarios by changing the price and function of robots to be installed, insights that consider the various situations are offered.

Findings

Though the increase in capacity saves much time for room service at a lower capacity level, the amount of time saved gradually decreases as the capacity increases. Besides, the installation strategy is divided into two cases depending on the purchase cost of robots.

Research limitations/implications

Currently, the studies focusing on the adoption of service robots from an operations view are rarely be found. To reduce the burden of investment cost, this study takes the unique approach to improve the operation policy of service robots by using the multi-capacity robots.

Practical implications

This study guides the hotel to install an adequate set of robots. The result confirms that the optimal installation set of robots is affected by various factors, such as the room service information, the hotel structure and the unit execution cycle.

Originality/value

After the outbreak of COVID-19, people avoid face-to-face contact and interest in non-contact service is growing. This paper deals with the efficient way to implement non-contact delivery through logistic robots, a timely and important topic.

Abstract

Purpose

This study examines the impact of response time on user experience for mobile applications and considers the moderating influence of gender and network environment on this relationship.

Design/methodology/approach

An experiment was conducted with 50 young adults to evaluate their user experience of a mobile application that simulates variations in network environment and response time. User experience was evaluated based on the three constituent dimensions of tolerance, acceptance, and satisfaction.

Findings

Analytical results demonstrate that response time not only adversely affects user experience of mobile applications, but that this effect is not homogeneous across the three dimensions of tolerance, acceptance and satisfaction. The findings also illustrate that gender moderates the effect of response time on user experience, however, the negative influence is more salient for males than females, which is opposite to our hypothesis. The joint moderating influence of gender and network environment turned out to be partly significant.

Practical implications

By illuminating users' tolerance, acceptance, and satisfaction with varied response times, findings from this study can inform the design of mobile applications such that desired levels of user experience can be assured with minimum resources.

Originality/value

Although response time has been hailed as a key determinant of user experience for desktop applications, there is a paucity of studies that have investigated the impact of response time on user experience for mobile applications. Furthermore, prior research on response time neglects the multi-dimensional nature of user experience. This study bridges the above mentioned knowledge gaps by delineating user experience into its constituent dimensions and clarifying the effects of response time on each of these dimensions.
