Abstract

Purpose

The purpose of this paper is to design a robust tracking algorithm which is suitable for the real-time requirement and solves the mistake labeling issue in the appearance model of trackers with the spare features.

Design/methodology/approach

This paper proposes a tracker to select the most discriminative randomly projected ferns and integrates a coarse-to-fine search strategy in this framework. First, the authors exploit multiple instance boosting learning to maximize the bag likelihood and select randomly projected fern from feature pool to degrade the effect of mistake labeling. Second, a coarse-to-fine search approach is first integrated into the framework of multiple instance learning (MIL) for less detections.

Findings

The quantitative and qualitative experiments demonstrate that the tracker has shown favorable performance in efficiency and effective among the competitors of tracking algorithms.

Originality/value

The proposed method selects the feature from the compressive domain by MIL AnyBoost and integrates the coarse-to-fine search strategy first to reduce the burden of detection. This paper designs a tracker with high speed and favorable results which is more suitable for real-time scene.

Abstract

Purpose

Prefabricated construction (PC) can benefit construction industry due to its high efficiency, energy saving, consumption reduction and safety. However, the high capital cost is a critical challenge hindering its development in China. The collaboration of PC stakeholders is conducive to improving cost management efficiency and optimizing resource allocation which has been ignored in previous studies. Therefore, this study aims to explore the collaboration paths of stakeholders in the process of solving critical cost influencing factors (CIFs) of PC to reduce costs.

Design/methodology/approach

Firstly, 25 CIFs and five main stakeholders that affect PC capital cost were identified through literature research and expert interviews. Then, questionnaires were used to investigate the relationship between stakeholders and CIFs from the perspectives of three stakeholder attributes of proximity, attitude and power, respectively. Finally, based on the survey data, three stakeholder-CIF networks from three attributes perspective and a comprehensive network were constructed and used for subsequent social network analysis.

Findings

(1) Stakeholders mainly show willingness and potential to collaborate on organization and management factors; (2) More stakeholders pay attention to incentive policies and the setting of prefabrication rates and assembly rates, while all stakeholders have the right to facilitate information and resource sharing in the PC supply chain; (3) The comprehensive network shows a core-periphery structure. As core stakeholders, contractor, designer and manufacturer are more likely to actively manage the 14 core CIFs.

Originality/value

This paper innovatively combined stakeholder and cost management in PC, and used two-mode network based on three stakeholder perspectives to reveal the collaboration potential and motivation of stakeholders in PC cost management. The findings not only provide guidance for stakeholders to find potential partners and optimize resource allocation in solving specific cost issues, but also facilitate stakeholders' sustainable collaboration to achieve PC's cost performance.

Abstract

Although an important facet of modernist architecture in which function plays a prominent role, building flexibility is not entirely a new concept. Its relevance transcends generations, allowing space and structure to evolve through time. This paper investigates the relationship among main building structures, infill elements, and space by studying examples in ancient Chinese architecture. It reveals the role of building owners, users, and craftsmen from a survey of historical documentation. In studying these examples, it is concluded that craftsmen in ancient China were involved not only during the construction phase but throughout the period of use as well. Thus, in select cases, the relationship between craftsmen and owners or users had been preserved for generations. Finally, this paper suggests potential strategies for the building industry and technology in the move towards sustainable development.

Abstract

Purpose

In the post-pandemic era urban ecosystem planning has become critically important. Given the emphasis on relevant issues concerning the complex interactions between human civilizations and natural systems within urban environments in the new normal, this article aims to enrich the field of knowledge management developing a cross-cultural analysis for clarifying the role of knowledge in planning and urban ecosystems.

Design/methodology/approach

This paper is conceptual in nature. Based on a theoretical foundation built by a critical literature review and data from the China Statistical Yearbook and China’s National Bureau of Statistics, this paper introduces some emerging real-impact topics regarding the connections between humanistic knowledge and urban planning. A comparative analysis between the capital city of Chang’an in the Tang dynasty of China and the capital city of Athens in Ancient Greek was used for explaining the influence of knowledge on successful urban planning.

Findings

The understanding the role of cross-cultural differences in knowledge management and practices for urban ecosystems offer the opportunities for rethinking consolidated approach to the interaction among social, economic, and environmental dimensions in urban settings.

Originality/value

This paper implies a new inter-disciplinary research field of great interest for the real impact KM community by illuminating how knowledge management is central in urban planning and across cultures.

Abstract

Purpose

Based on object–object congruity, this study aims to clarify the driving factors and antecedent mechanism of tourists’ willingness to purchase intangible cultural heritage (ICH)-souvenirs.

Design/methodology/approach

This study used a five-point Likert scale to collect data and proposed a structural equation model to explore this issue.

Findings

ICH-inheritor/souvenir-congruity is positively related to tourists’ purchase intention for ICH-souvenirs and perceived authenticity; perceived authenticity and brand identity play a chain mediating effect between ICH-inheritor/souvenir-congruity and the purchase intention for ICH-souvenirs.

Research limitations/implications

This paper excludes individual, situational and cultural factors, ignoring the possible moderating roles of these factors. This treatment simplifies the feasibility of the present study but might lead to the deviation between the results of the current research and the actual outcomes.

Practical implications

The retailers of ICH-souvenirs should encourage the ICH-inheritors to endorse and promote their products while creating. They could tell a good story about their experience or create entertainment experiences for tourists through hand-in-hand teaching.

Originality/value

This study explores the driving factors and antecedent mechanism of tourists’ purchase intention for ICH-souvenirs from the third perspective of image congruity theory, namely, object–object congruity.

Recuerdos del patrimonio cultural inmaterial:

la influencia de la consistencia de la imagen y la marca en la intención de compra de los turistas

Resumen

Propósito

Basado en la congruencia objeto-objeto, el presente estudio busca esclarecer los factores impulsores y el mecanismo antecedente sobre la disposición de los turistas a adquirir recuerdos del PCI.

Diseño/metodología/enfoque

El presente estudio utiliza una escala de Likert de cinco puntos para recopilar datos y plantea un Modelo de Ecuaciones Estructurales (MEE) para estudiar este asunto.

Resultados

La congruencia entre el heredero/recuerdo del PCI se relaciona de forma positiva con la intención de compra de recuerdos del PCI por parte de los turistas y con la autenticidad percibida; la autenticidad percibida y la identidad de marca ejercen un efecto mediador en cadena entre la congruencia entre el heredero/recuerdo del PCI y la intención de compra de recuerdos del PCI.

Originalidad/valor

El presente estudio explora el mecanismo antecedente de la intención de compra de los turistas de recuerdos de PCI a partir de la tercera perspectiva de la teoría de congruencia de la imagen (la congruencia objeto-objeto).

Implicaciones teóricas

El presente estudio justifica la validez y racionalidad de la congruencia objeto-objeto, extendiendo la teoría de la congruencia de imagen.

Implicaciones prácticas

Los minoristas de los recuerdos del PCI deben fomentar que los herederos del PCI respalden y promocionen sus productos al mismo tiempo que los crean. Ellos pueden contar sus propias experiencias o crear experiencias entretenidas para turistas mediante la enseñanza mediante ejemplos.

Limitaciones/implicaciones del estudio

El presente documento no tiene en cuenta los factores individuales, situacionales y culturales e ignora el posible papel moderador de estos factores. Dicho tratamiento simplifica la viabilidad de este estudio, aunque podría dar lugar a una desviación entre los resultados de la presente investigación y los resultados reales.
