Abstract

Purpose

Vision transformers (ViT) detectors excel in processing natural images. However, when processing remote sensing images (RSIs), ViT methods generally exhibit inferior accuracy compared to approaches based on convolutional neural networks (CNNs). Recently, researchers have proposed various structural optimization strategies to enhance the performance of ViT detectors, but the progress has been insignificant. We contend that the frequent scarcity of RSI samples is the primary cause of this problem, and model modifications alone cannot solve it.

Design/methodology/approach

To address this, we introduce a faster RCNN-based approach, termed QAGA-Net, which significantly enhances the performance of ViT detectors in RSI recognition. Initially, we propose a novel quantitative augmentation learning (QAL) strategy to address the sparse data distribution in RSIs. This strategy is integrated as the QAL module, a plug-and-play component active exclusively during the model’s training phase. Subsequently, we enhanced the feature pyramid network (FPN) by introducing two efficient modules: a global attention (GA) module to model long-range feature dependencies and enhance multi-scale information fusion, and an efficient pooling (EP) module to optimize the model’s capability to understand both high and low frequency information. Importantly, QAGA-Net has a compact model size and achieves a balance between computational efficiency and accuracy.

Findings

We verified the performance of QAGA-Net by using two different efficient ViT models as the detector’s backbone. Extensive experiments on the NWPU-10 and DIOR20 datasets demonstrate that QAGA-Net achieves superior accuracy compared to 23 other ViT or CNN methods in the literature. Specifically, QAGA-Net shows an increase in mAP by 2.1% or 2.6% on the challenging DIOR20 dataset when compared to the top-ranked CNN or ViT detectors, respectively.

Originality/value

This paper highlights the impact of sparse data distribution on ViT detection performance. To address this, we introduce a fundamentally data-driven approach: the QAL module. Additionally, we introduced two efficient modules to enhance the performance of FPN. More importantly, our strategy has the potential to collaborate with other ViT detectors, as the proposed method does not require any structural modifications to the ViT backbone.

Abstract

Purpose

The paper aims to examine the relationships among marathon spectator motivation, satisfaction and behavioral intention in China.

Design/methodology/approach

Date were collected from three Chinese marathon races. The paper presents the conceptual model of the study and adopted a mixed method to identify the motivations of marathon spectators; structural equation modeling (SEM) was used to test the measurement and substantive models; regression analysis was used to detect the specific effects of the various spectator motivations on spectator satisfaction and behavioral intention.

Findings

The paper provides empirical evidences about how marathon spectator motivation affects the behavioral intention. The research results from a path analysis of the spectator motivation–satisfaction–behavioral intention model show that: spectator motivation has significant positive effects on behavioral intention, the indirect path dominates the total effect of motivation on behavioral intention via satisfaction as a mediating variable; satisfaction is positively associated with behavioral intention, and it plays mediate role between spectator motivation and behavioral intention. The result of regression analysis indicates that various spectator motivations have different influences on the satisfaction and behavioral intention, motives of excitement and diversion have significant effect on satisfaction and behavioral intention, but socialization motive is not significantly associated with the satisfaction and behavioral intention.

Originality/value

This paper first fulfills an identified need to explore mass sports event spectator motivations and its influential mechanism on behavioral intention among Chinese marathon races by survey. It contributes greatly to the literature of mass sports spectator motivation and consumption theory, provides important managerial implications for Chinese sports organizations as to how to improve spectator orientation degree.

Abstract

Purpose

Grounded in upper echelons theory (UET) and conflict theory, the purpose of this study is to analyzes the innovative behavior of family firms from the perspective of the cognitive differences between successors and senior managers.

Design/methodology/approach

This research employed a sample listed family firms in China. The obtained results were subjected to hierarchical regression analysis, complemented by rigorous model robustness testing through propensity score matching and regression with substitution variables.

Findings

Successors engender task conflicts with family members in the top management team (TMT) due to cognitive differences, thereby stimulating corporate innovation. Conversely, successors engender relationship conflicts with non-family members in the TMT, impeding innovation. Furthermore, the performance expectations and the gender of the successor CEO also influence the relationship between cognitive differences and innovation between the successor and the TMT.

Originality/value

This study's originality and value lie in its innovative application of UET and conflict perspectives to dissect the intricate layers of intergenerational cognitive differences and their impact on the innovative behavior of family firms. It augments our comprehension of how the internal dynamics within family firms shape strategic innovation decisions.

Abstract

Purpose

This study aims to explore the value of pocket parks and associated factors, as well as the differences between pocket parks and other green spaces, and finally to identify the role of pocket parks in cities.

Design/methodology/approach

This study adopts a systematic literature review method to identify 85 articles from the Web of Science and other sources. The Nvivo12plus software was employed to qualitatively analyse the value of pocket parks, and the key associated factors were visualised via the NVivo word cloud function.

Findings

As a result, pocket parks reflected high social, environmental ecological, cultural aesthetic values but low economic value. Compared to other large-scale green spaces, the particularity of pocket parks lies in their ambiguity and temporality of space and high reliance on the surrounding environment. Small and scattered pocket parks in the city are like “convenience stores” and “green magnets”, and connectivity should be strengthened to promote urban regeneration.

Originality/value

Compared with previous studies that mostly focused on large urban green spaces, the originality of this study is that it elaborates on the importance and values of pocket parks and proposes the particularity and roles of pocket parks in cities, which enriches the theoretical knowledge of pocket parks. In terms of practical applications, the proposed diverse values and associated factors contribute to guiding the planning, management and operation of pocket parks. Moreover, the roles of pocket parks help enhance park connectivity and establish a park network system.

Abstract

Purpose

Live-streaming platforms emphasize dynamic social interaction and fan engagement. Users integrate into the live-streaming community through continuous social learning activities, such as sending bullet comments, reviewing comments and interacting with celebrities. However, comprehensive research on the transactional intricacies of live-streaming e-commerce from the perspectives of community and learning is still lacking.

Design/methodology/approach

Focusing on the behavior characteristics of the reference group represented by online celebrities and fans in the live-streaming environment, this study utilized social learning as the theoretical basis to examine how reference groups affect consumer purchase intention through a series of intermediary effects. An empirical investigation and machine learning algorithms were utilized to explore and verify the hypothesized model.

Findings

The results show that: (1) reference groups’ behavior positively stimulated social presence and enhanced consumer purchase intention through the chain-mediating effect of social presence and trust in online celebrities; (2) celebrity characteristics (professionalism, attractiveness and interactivity) positively impacted consumer trust; (3) in addition, machine learning algorithms substantiated that reference groups’ behavior, social presence, trust and celebrity characteristics had a remarkably robust predictive effect on purchase intention.

Originality/value

These findings hold theoretical implications for understanding how the social community affects consumers’ purchase intention in the live-streaming context and practical significance for marketing strategies toward live-streaming e-commerce.
