This paper aims to propose a robust and efficient method for vanishing point detection in unstructured road scenes.

Abstract

Purpose

This paper aims to propose a robust and efficient method for vanishing point detection in unstructured road scenes.

Design/methodology/approach

The proposed method includes two main stages: drivable region estimation and vanishing point detection. In drivable region estimation stage, the road image is segmented into a set of patches; then the drivable region is estimated by the patch-wise manifold ranking. In vanishing point detection stage, the LSD method is used to extract the straight lines; then a series of principles are proposed to remove the noise lines. Finally, the vanishing point is detected by a novel voting strategy.

Findings

The proposed method is validated on various unstructured road images collected from the real world. It is more robust and more efficient than the state-of-the-art method and the other three recent methods. Experimental results demonstrate that the detected vanishing point is practical for vision-sensor-based navigation in complex unstructured road scenes.

Originality/value

This paper proposes a patch-wise manifold ranking method to estimate the drivable region that contains most of the informative clues for vanishing point detection. Based on the removal of the noise lines through a series of principles, a novel voting strategy is proposed to detect the vanishing point.

Abstract

Purpose

This paper aims to propose a “Four-F (finding facts, fostering alternates, fulfilling implementation and feasibility testing)” action plan to global food service businesses (FSB) such as restaurants (dine-in/take away) to build resilience during times of global crises. The 2019 Coronavirus disease and FSBs apply as working examples elaborating the proposed Four-F action plan with several managerial implications for the internal and external stakeholders of FSBs.

Design/methodology/approach

The method involves reviewing and coding 108 articles using the PRISMA approach, then applying findings to develop the Four-F action plan integrating multiple theoretical concepts (such as stakeholder, crisis management and dynamic capabilities).

Findings

There are two key findings. First, though all four crisis phases should be considered by decision-makers as part of their contingency planning process, the pre and post-crisis stages need higher attention. Second, the Four-F action plan provides specific recommendations to FSBs stakeholders (consumers, suppliers and government) for each crisis phase (pre-crisis, crisis emergence, crisis occurrence and post-crisis).

Originality/value

To the best of the authors’ knowledge, this is the first paper that has incorporated multiple theoretical frameworks (stakeholder theory, crisis management and dynamic capabilities) within the FSBs context and provided the Four-F action plan for decision-makers to understand and manage crisis phases.

Abstract

Purpose

This conceptual paper aims to provide a further understanding of the impact of economic policy uncertainty (EPU), news framing and information overload on panic buying behavior during the COVID-19 pandemic.

Design/methodology/approach

Drawing on earlier research and news releases about the COVID-19 outbreak, this paper advances testable propositions based on the protection motivation theory and information processing theory.

Findings

This paper infers that the major shift in consumer decision-making towards panic buying is a result of high EPU. International reports have contributed to deepening this uncertainty, and the consequences of this EPU are expected to affect the economic recovery through 2022. Furthermore, the adoption of particular frames of the pandemic has played a key role in the dissemination of misinformation and fake news during the public health crisis and affected purchasing decisions. The study also infers that the perceived threat among consumers is driven by information overload as a source of mistrust towards economic and health information sources.

Originality/value

This paper addresses two theoretical gaps associated with consumer buying behaviour. First, it highlights the impact of EPU, as a macroeconomic indicator, on consumer buying behaviour. Second, this paper is an attempt to integrate theories from different disciplines to foster an adequate understanding of buying behavior during the COVID-19 outbreak period.

The purpose of this study is to evaluate the impact of reward structure on the customer's value perception of the program, loyalty to the program and loyalty to the firm.

Abstract

Purpose

The purpose of this study is to evaluate the impact of reward structure on the customer's value perception of the program, loyalty to the program and loyalty to the firm.

Design/methodology/approach

A 2 (type of reward) x 2 (timing of redemption) between subjects experimental design was conducted. In addition, the indirect effect of the customer's value perception of the program on loyalty to the firm via loyalty to the program is tested with Hayes and Preacher's mediation procedure.

Findings

Study results indicated that type of reward has a positive impact on the perceived value of a loyalty program. Program loyalty mediates the relationship between the perceived value of the loyalty program and customer loyalty, as well as the relationship between type of reward and customer loyalty.

Originality/value

The findings of this study demonstrate the importance of the type and timing of loyalty program rewards on customer perceptions of the value of the loyalty program. In addition, this study is a step forward in providing a deep understanding of the impact of such perceptions on loyalty. These findings fill a number of research gaps and provide tangible guidance for practitioners.

This study provides insights on the perceptions of residents in destinations offering different tourism products at different levels of tourism development.

Abstract

Purpose

This study provides insights on the perceptions of residents in destinations offering different tourism products at different levels of tourism development.

Design/methodology/approach

A total of 1,122 valid responses were gathered through surveys from the residents of three unique destinations, with different levels of tourism development. Non-parametric tests were performed since the data was gathered on an ordinal scale and not distributed normally.

Findings

The tourism perceptions of the residents formed a five-factor structure, namely “socioecological negative”, “socioeconomic positive”, “socioecological development (wellbeing)”, “negative perceptions of tourism” and “tendency to become visitor”. All dimensions except for “socioeconomic positive” differed significantly by destinations in terms of level of tourism development or type of tourism product offered.

Research limitations/implications

Residents' perceptions of tourism differ based on different tourism products and different levels of tourism development of destinations. The residents of the most mature destinations in terms of tourism development have the most negative perceptions of tourism.

Originality/value

Although there are studies investigating how residents' perceptions differ based on the level of tourism development of destinations, this study, with its holistic approach, aims to provide insights on how residents' perceptions of tourism differ based on the tourism products offered by different destinations. The selected destinations differ from each other in both their level of tourism involvement and products they offer, hence the originality of the current study with its unique contribution to the related body of knowledge.
