Abstract
Web‐based document management applications serve to store, organize, and manage a collection of documents within the context of a building project. The organization of documents, using mechanisms for indexing and relating these, aims to build an information structure that supports effective searching and browsing. We present a methodology for a stronger integration of project documents of different formats into a rich, highly interrelated, information structure. Specifically, we propose a decomposition of project documents by content in relation to a semantic structure for the categorization of document components. We consider a notion of typologies from architecture as a guide for constructing such a semantic structure. We discuss the application of this methodology to building projects, and propose its use in Web‐based document management applications in the AEC industry. As an illustration of this methodology, we describe a prototype application, as a presentation tool for architectural analyses in an educational context.

Abstract
Purpose
The purpose of this paper is to assess the validity of Weller's b-ω flamelet model for practical swirl-stabilized combustion applications.
Design/methodology/approach
Swirl-stabilized premixed flame behavior is investigated utilizing an atmospheric combustor test rig. Swirl number of the flow is 0.74 with a cold flow Reynolds number of 19,400 based on the hydraulic diameter at the inlet pipe. Operating condition corresponds to an equivalence ratio of 0.7 at a thermal load of 20.4 kW. Reacting flow was seeded with TiO2 particles, and velocity distribution at the center plane was measured utilizing particle image velocimetry. These results serve as a validation dataset for numerical simulations. An open-source computational fluid dynamics (CFD) code library (OpenFOAM) is used for numerical computations. These unsteady Reynolds averaged Navier Stokes (RANS) computations were performed at the same load condition corresponding to experimental data. Parallel numerical simulations were carried out on 128 processor cores. To resolve turbulence, Menter's k-ω shear stress transport model was utilized; flame behavior, on the other hand, was described by Weller's b-ω flamelet model. A block-structured all-hexahedral mesh was used.
Findings
It is observed that two counter-rotating vortices in the main recirculation zone are responsible for flame stabilization. Weak secondary recirculation zones are also present at the sides above the dump plane. Flame front location was inferred from Mie scattering images. Experimental findings show that the flame anchors both on the tip of the center body and also at the rim of the outlet pipe. Numerical simulations capture the complex interactions between the flame and the turbulent flow. These results qualitatively agree with the flame structure observed experimentally.
Practical implications
Swirl-stabilized combustion systems are used in many practical applications ranging from aeroengines to land-based power generation systems. There are implications regarding the understanding of these combustion systems.
Social implications
Better understanding of combustion systems contributes to better performing turbine engines and reduced emissions with implications for the entire society.
Originality/value
The paper provides experimental insight into the application of a combustion model for a flame configuration of practical interest.

Abstract
Purpose
Even after establishing their business successfully, many business owners get demotivated, and it leads to unwillingness to grow. This study aims to propose a comprehensive model that represents interrelationships among various personal factors affecting “unwillingness to grow.”
Design/methodology/approach
The personal factors for unwillingness to grow were identified by extant literature, and expert interviews were conducted to establish the contextual relationships among these factors. The interrelationships among the filtered variables have been done using interpretive structural modeling (ISM) and MICMAC analysis was done to determine the importance of each factor in influencing “unwillingness to grow.”
Findings
In total, 30 personal attributes were identified from previous literature, out of which 15 were selected for the final study. The result identifies 7 variables having a strong impact on “unwillingness to grow.” These attributes are “absence of strong network,” “lack of vision,” “lack of proactiveness,” “reluctance to involve external consultants,” “absence of/small founding team,” “lack of ambition” and “improper attitude.”
Originality/value
The research attempts to create a bricolage of all the important personal factors affecting “unwillingness to grow.” Previous researches have used few attributes, but with the help of ISM, a graphical modeling technique, it became possible to draw interrelationship between 15 attributes. Further, with the help of MICMAC, the importance of each attribute was determined.

Abstract
Entrepreneurial orientation (EO) and entrepreneurial intentions (EI) both are prominent factors in the entrepreneurship domain to predict entrepreneurial behavior. Despite the fact, association between the EO sub-aspects and EI, as well as the indirect influence of the personality characteristic (Openness), has not been extensively investigated. The focus of this research study is to examine the association between sub-dimensions of EO, proactiveness, risk-taking, and innovativeness, and EI incorporating personality trait openness to experience (OTE) as mediating variable. Data is gathered from 164 professional course students. For the data analysis purpose, mediation analysis, multiple regression and confirmatory factor analysis (CFA) have been performed. Findings imply that all the sub-aspects of EO are significantly correlated with EI and personality trait OTE acted as mediating construct in link amidst EO and EI. Practical and theoretical contribution have been discussed in this study.

Abstract
The chapter discusses how adolescents are moving beyond the dichotomy of biological and linguistic socialization, forming interpretive meanings at home through the reading of literature in their mother tongue, Bengali. Involving cultural relevance and non-vulnerability, the chapter conceptualizes “leisure activities” and “leisure pursuits” of reading practice of the IXth and Xth graders from both Bengali and English medium schools in Kolkata. The discussion from the theoretical construction mentions the further conceptualization of reading habits and language choice. This is where adolescents derive their agency. Adolescents from the Indian and especially from the Bengali perspective have a path of colonial discourse. From historical standpoint, the change in Bengali language and its grammar structure has influenced the acceptance of Bengali literature among adolescents in varying degrees through generations. Using mixed methods and content analysis, the chapter focuses on young teenagers’ narration on the way they maneuver curriculum and literature in their respective homes. Authors, for example, Sunil Gangopadhyay, Satyajit Ray, and Bibhutibhushan Bandyopadhyay, form the Bengali identity construction in the present time. Rabindranath Tagore’s, Sarat Chandra Chattopadhyay’s and Bankim Chandra Chatterjee’s works are always prevalent in the Bengali language syllabus. These are considered the foundational modern literary figures of pre-independent India. These are taught from a nationalist and gender discourse perspective. The adolescents in this chapter also read those at a minimum level at home and attempt to juggle the difficult vocabulary involved. The simple language of post-independent literature is much sought after by teenagers compared to pre-independent literature. Sunil Gangopadhyay’s Kakababu series, Satyajit Ray’s Feluda and Professor Shanku series, and Bibhutibhushan Bandopadhyay’s Chander Pahar stand out among the adolescents from both English and Bengali medium unanimously in this chapter.

Abstract
The purpose of this chapter is to conduct a structured literature review to examine the relationship between entrepreneurship and emotional intelligence in academic settings as well as the current entrepreneurship pedagogy for flexible, innovative and creative graduates. One hundred and twenty-eight peer-reviewed papers were analysed based on Webster’s and Watson’s (2002) methodology. Papers classified into three topics and a content analysis was implemented to discuss about the publication year, journals, authors, frequency of keywords and research method adopted. The contribution of this chapter is twofold. It is a bibliometric study which provides a macropicture of a research field, its evolution and connections among studies, in order to be a starting point for future researchers who are already studying entrepreneurial education or entrepreneurship-related scientific areas. Also, this chapter helps academics to improve educational programmes and curriculum to increase students’ entrepreneurial intention taking into account the factors that affect it.

Abstract
Geotechnologies have a long tradition in several areas of society and research. The recent development of the ‘Internet of Everything’ (IoE) and Geographic Information Systems (GIS) technologies opened several doors to the contribution of tourism. Emergent technologies contributions to tourism and planning such as web mapping, augmented reality (AR), crowdsourcing and crowdsensing are relatively recent, and there is a lack of research around their potential for Creative Tourism enhancement. For example, combining web mapping with AR or storytelling can be an excellent contribution to operators, planners and tourists. For research purposes, new opportunities are open, particularly by integrating community-shared data. It is well known for the popularity of social networks, the exponential growth of photo sharing, but few studies have been implemented to understand their contribution to research. This chapter focuses on emerging geotechnologies concerning cultural mapping, Creative Tourism and sustainability. Since it is a new growing niche, more research is needed to develop and understand the potential of new approaches. Besides traditional techniques such as quantitative (e.g. surveys) and qualitative ones (e.g. interviews, focus groups and world café), it revises the role of geotechnologies on Creative Tourism development and growing activities. Results from case studies from Europe are analysed.

Abstract
Purpose
The purpose of this paper is to establish a conceptual model adopted from a strategy-structure-performance paradigm for investigating the fit between the supply chain integration and halal food supply chain integrity and the impact of halal food supply chain integrity on firms’ performance in a Malaysian context.
Design/methodology/approach
This study comprises a sample of a halal manufacturing firm in Malaysia. A cross-sectional research design was used in this study. Data were gathered based on mailed and personally administered questionnaires. SmartPLS was used to analyse the 254 valid responses.
Findings
The research findings indicate that internal integration and strategy have positive impact on halal food supply chain integrity. The study results confirmed that customer integration and supplier integration contributes to halal food supply chain integrity. It also finds that halal food supply chain integrity has a significantly positive impact.
Research limitations/implications
The results suggested that a strategic collaboration with the supplier pivoted around the quality and integrity of the raw materials should be undertaken.
Practical implications
The results from this study supports that the managers should adopt all halal food supply chain integrity components to achieve a superior performance. Even though some of the components did not yield significant results in terms of their relationships with firms’ performance, these dimensions were generally related to the standardised industry requirements, such as certifications.
Originality/value
The findings are original and unique and are based on established theories from the literature on supply chain management practices. The research findings are useful to academics and policymakers interested in fostering a halal supply chain in Malaysia.

Abstract
Purpose
This paper presents a critical review of studies which map the urban environment using continuous physiological data collection. A conceptual model is consequently presented for mitigating urban stress at the city and the user level.
Design/methodology/approach
The study reviews relevant publications, examining the tools used for data collection and the methods used for data analysis and data fusion. The relationship between urban features and physiological responses is also examined.
Findings
The review showed that the continuous monitoring of physiological data in the urban environment can be used for location-aware stress detection and urban emotion mapping. The combination of physiological and contextual data helps researchers understand how the urban environment affects the human body. The review indicated a relationship between some urban features (green, land use, traffic, isovist parameters) and physiological responses, though more research is needed to solidify the existence of the identified links. The review also identified many theoretical, methodological and practical issues which hinder further research in this area.
Originality/value
While there is large potential in this field, there has been no review of studies which map continuously physiological data in the urban environment. This study covers this gap and introduces a novel conceptual model for mitigating urban stress.

Abstract
Purpose
The purpose of this study is to investigate the impact of the Big Five personality traits on the entrepreneurial intentions of undergrad university students in Jordan. It further investigates the mediating role of entrepreneurial alertness.
Design/methodology/approach
A quantitative survey method was conducted with a convenience sample of Jordanian university students. A total of 323 valid questionnaires were received and analyzed. A structural equation modeling with partial least square (PLS) is used to analyze data.
Findings
Results revealed that conscientiousness, openness and alertness were associated with entrepreneurial intention. Extraversion and openness were associated with alertness, while agreeableness and neuroticism were unrelated to either outcome. Finally, alertness mediates the relationship between extraversion and openness with entrepreneurial intention.
Originality/value
There is a lack of previous studies investigating the relationship between the Big Five personality traits and students’ entrepreneurial intentions in Jordan, particularly the role of mediating variables in this relationship. This study is considered the first one that examined the mediating role of entrepreneurial alertness in the relationship between personality traits and entrepreneurial intentions.
