Abstract
Purpose
Evidence of the link between major sports events and increased participation at grassroots level is somewhat mixed. The purpose of this paper is to examine attitudinal changes to sport participation among spectators associated with seven sports events held in Great Britain in 2014.
Design/methodology/approach
Primary data were gathered from 4,590 spectators aged 16 and over who attended one of the events. Both positive (inspiration) effects and negative (discouragement) effects were considered through the lens of the transtheoretical model (TTM).
Findings
The evidence from this research indicates that event audiences belong primarily to the latter (more active) stages of the TTM. It was also found that attending sports events can further fuel the existing desire of contemplators to increase participation, whereas the catalytic effect among pre-contemplators is arguably less potent. Virtually no discouragement effects were observed across the different TTM stages.
Research limitations/implications
The research stops short of measuring actual changes in sport participation post-event of individuals in the different TTM stages and any attribution of such behaviour changes to events. This is both a limitation of the current research and a natural direction for future research.
Practical implications
The main implications for promoting sport participation through the medium of sports events include attracting more people in the early stages of the TTM, greater collaboration between different event stakeholders and the building of sport participation strategies into the event planning phase.
Originality/value
Models of behaviour change such as the TTM have seldom been applied to document the current and/or planned sport participation behaviour of individuals in a sport event context or to examine attitudinal changes towards sport as a result of attending an event. An adapted version of the TTM has been proposed to overcome the limitations of the traditional model.

Abstract
Purpose
To obtain a vascularized autologous bone graft by in-vivo tissue transformation, a biocompatible tissue transformation mold (TTM) is needed. An ideal TTM is of high geometric accuracy and X-ray radiolucent for monitoring the bone tissue formation. The purpose of this study is to present the TTM design and fabrication process, using 3D reconstruction, stereolithography (SLA) and silicone molding.
Design/methodology/approach
The rat mandible, the targeted bone graft, was scanned by micro-computed tomography (CT). From the micro-CT images, the 3D mandible model was identified and used as the cavity geometry to design the TTM. The TTM was fabricated by molding the biocompatible and radiolucent silicone in the SLA molds. This TTM was implanted in a rat for in vivo tests on its biocompatibility and X-ray radiolucency.
Findings
SLA can fabricate the TTM with a cavity shape that accurately replicates that of the rat mandible. The bone formation inside of the silicone TTM can be observed by X-ray. The TTM is feasible for in vivo tissue transformation for vascularized bone reconstruction.
Research limitations/implications
Research of the dimensional and geometrical accuracy of the TTM cavity is required in the future study of this process.
Practical implications
The TTM fabricated in this presented approach has been used for in-vivo tissue transformation. This technique can be implemented for bone reconstruction.
Originality/value
The precision fabrication of the TTMs for in-vivo tissue transformation into autogenous vascularized bone grafts with complex structures was achieved by using SLA, micro-CT and silicone molding.

To study the effects of velocity correction schemes for a temperature transforming model (TTM) for convection controlled solid‐liquid phase‐change problem.
Abstract
Purpose
To study the effects of velocity correction schemes for a temperature transforming model (TTM) for convection controlled solid‐liquid phase‐change problem.
Design/methodology/approach
The effects of three different solid velocity correction schemes, the ramped switch‐off method (RSOM), the ramped source term method (RSTM) and the variable viscosity method (VVM), on a TTM for numerical simulation of convection controlled solid‐liquid phase‐change problems are investigated in this paper. The comparison is accomplished by analyzing numerical simulation and experimental results of a convection/diffusion phase‐change problem in a rectangular cavity. Model consistency of the discretized TTM is also examined in this paper. The simulation results using RSOM, RSTM and VVM in TTM are compared with experimental results.
Findings
In order to efficiently use the discretized TTM model and obtain convergent and reasonable results, a grid size must be chosen with a suitable time step (which should not be too small). Applications of RSOM and RSTM‐TTM yield identical results which are more accurate than VVM.
Originality/value
This paper provides generalized guidelines about the solid velocity correction scheme and criteria for selection of time step/grid size for the convection controlled phase change problem.

Abstract
Over the last two decades, Japanese products have challenged Western ones, not only in terms of cost but also on quality, reliability and delivery. This has meant that meeting customer needs on time has now entered the competitive equation. Hence, in the 1990s, time to market (TTM) has become a focal point in achieving competitive advantage in the marketplace. Presents an overview of TTM and of how to do it. Considers the costs and benefits of TTM, and uses two case studies to compare and contrast the effect of adopting TTM and ignoring it. Looks at the key factors of: tools and techniques; technology; team management and logistics, with practical examples of the main points in achieving TTM successfully.

Abstract
Purpose
A crucial issue in educational management refers to helping teachers reach their full potential and manage their talents. Although managing talent is advised as an essential resource for organizational transformation to maximize performance and to promote a school’s knowledge capital increase, Teachers’ talent management (TTM) is not an agreed-upon concept in the literature. The aim of this study is threefold: (1) to propose a theoretical and operational TTM definition, (2) to develop a test to measure TTM and (3) to discuss the value of TTM implementation in educational settings.
Design/methodology/approach
A psychometric validation design according to international standards for test development is implemented. A cross-sectional intentional sampling with 200 schools is used for obtaining reliability and validity evidence. We operationalized TTM using 9 factors (10 items per factor, 6-point Likert scale): attraction, selection, development, retention, succession, climate, culture, evaluation and knowledge management.
Findings
Results show adequate evidence of reliability and validity, focusing on items' content and latent structure. The combined use of structural equation models (SEM) and psychometric networks (PN) detects a six-factor model with a test reduced version including 61 items, getting 64.28% of the total explained variance and adequate reliability indices and factor loadings.
Originality/value
The Teachers' Talent Management Assessment Test (TTMAT) can contribute educational institutions to create a culture of excellence and deliver the best possible education to their students. Educational transformation will only happen if teachers are professionalized, trained, motivated and supported to inspire and to guide their learners to reach their objectives and well-being.

Abstract
Purpose
This paper seeks to provide an insight into the design and development of the thermal test model (TTM) of X‐Sat, a 120 kg class micro‐satellite, being developed at the Centre. This model was specifically constructed for carrying out a thermal balance test (TBT) in a 4 m diameter vertical thermal vacuum chamber.
Design/methodology/approach
The construction of the thermal model followed a structural mock‐up model which was modified thermally to suit the purpose. Specific and careful consideration was given to the geometry and, more importantly, thermal characteristics such as thermal mass, surface properties, etc. to mimic the actual satellite configuration as closely as possible. Test plans were devised to qualify the fabricated components to meet the out‐gassing and other thermal requirements for the model. Design and qualification of supporting frame and linkages for TBT are also covered.
Findings
It is possible to simulate the thermal characteristics of a micro‐satellite in orbit under a different mission scenario through proper scaling and using alternative material options while developing TTM.
Originality/value
The paper discusses in detail the simplified cost‐effective approach of constructing TTM and also outlines the various issues to be considered for a TBT. It provides valuable information needed for micro‐satellite designers.

Abstract
Purpose
Based on the humane entrepreneurship perspective, this study examines the mediating relationship of organizational trust (OT) between corporate entrepreneurship (CE) and turnover intention (TI). In addition, it tests the moderating role of top talent management (TTM) between corporate entrepreneurship and OT.
Design/methodology/approach
This study uses a multi-level research method to provide a conceptually comprehensive understanding of how CE works in an organization by testing the relationship between organizational practices and employees' outcomes.
Findings
This study found the mediating role of OT between cooperate entrepreneurship and employee TI. The authors also found the moderating role of TTM between CE and OT.
Originality/value
In this study, it is meaningful that OT is set as a mediating variable to identify the relationship between CE and workers' attitudes (TI). Although previous studies have shown a positive correlation between CE and TI, there was a lack of specific research on the indirect process by which CE affects workers' attitudes. This study looked more closely at the impact of CE on workers' attitudes using a multiple quasi-analysis.

Abstract
Purpose
This review aims to describe the effectiveness of education with the transtheoretical model (TTM)-based on the self-care behavior of hypertension patients.
Design/methodology/approach
A systematic literature search was carried out on four databases: PubMed, Science Direct, Cochrane and Grey literature to identify studies reported in English which were published in the last ten years. The literature search was conducted from November 13 to December 10, 2020.
Findings
Based on the six studies that have been analyzed, TTM is effective in changing the stage of change and behavior of hypertension patients. These behavioral changes have an impact on the patient's controlled blood pressure. Various types of TTM-based educational interventions can be used, but the tailored behavior intervention is the most appropriate one with a minimum intervention duration of six months. Educational intervention is carried out through combine counseling and education using electronic media.
Originality/value
This review presents the effectiveness of transtheoretical-based health education in changing the self-care behavior of hypertension patients accompanied by evidence-based on its implementation. There is a high and unclear risk of bias on several items influence this systematic outcome. Nevertheless, this review can still provide an overview of the effectiveness of education based on the TTM in hypertension patients about the quality results of the reviewed studies.

Abstract
Purpose
The purpose of this paper is to present a novel method for integrating of chaotic exploration and thinning‐based topological mapping to deal with the “traverse targets and return” problem applied for robot navigation in unknown environments. This new strategy can guarantee the robot stronger ability of exploring unknown environments, as well as recording and selecting optimal trajectory to return.
Design/methodology/approach
The chaotic dynamic evolution of controlled multi‐scroll system is linked to the multi‐sensory perception and reactive behaviors of a mobile robot. The thinning‐based topological map (TTM), as the contextual layer of the cognitive system, is adopted to achieve the environmental recording in the process of robot exploration and navigation. Once the robot arrives at the terminal target via avoiding all the obstacles, the TTM has been built in real time. Based on the records in the topological map, a short and smooth point‐to‐point path is generated to achieve the exit from target and to move back to the starting point.
Findings
The simulation results confirmed that the proposed solution is suitable to resolve the robot's tasks of obstacle avoidance, target retrieving, and return, also has better performance than traditional strategies.
Originality/value
The presented novel method focuses integration of chaotic exploration and TTM self‐construction. The chaotic perception and control technique permits the robot to explore most of the environmental information within the smallest explored area. The introduced topological map, generated by applying a thinning algorithm, guarantees a short and smooth returning trajectory for the robot.

Abstract
Purpose
The purpose of this study is to determine how transtheoretical model (TTM) constructions change through nutrition education for fat intake modification among overweight and obese women living in Shazand city, Iran.
Design/methodology/approach
A semi-experimental design with intervention and control groups (50 women in each group) was performed. TTM constructions for dietary fat intake were measured through a questionnaire in four phases: before the intervention, immediately, one month and six months after the intervention. Participants in two groups were classified into inactive and active subgroups, based on their determined stage of change. Then in the intervention group, each subgroup received a separate education program of five or eight sessions for the active and inactive subgroups, respectively.
Findings
The intervention resulted in significant progress in participants' stage of change compared to the control group (p = 0.002). Also, it resulted in an increase in the self-efficacy and decisional balance scores in both of the intervention subgroups, with these effects being more pronounced in the inactive subgroup, and these significant differences, compared to the control group, remained in the third and fourth phases. The intervention also positively impacted the behavioral processes, but this effect was not so long-lasting and decreased after six months.
Originality/value
The results indicated the intervention effectiveness and the necessity of planning educational interventions to change fat consumption behavior. This study provides further insight into effective and sustainable nutrition education strategies based on behavioral change stages rather than traditional approaches. These methods should be used to design group interventions to change individuals' health behavior in future works.
