Abstract
Purpose
Williams and Williams (2012, 2017) find multiple entrepreneurial motivations are experienced by entrepreneurs in deprived areas at different points in time. Drawing on this prior work this study aims to explore how and why the shifted motivations evolve, as well as, what factors cause this change in deprived areas. The work draws upon temporal motivational theory (TMT) that considers the influence of individuals' needs in determining their time-sensitive motivation.
Design/methodology/approach
Six semi-structured interviews with actual entrepreneurs are used to collect qualitative data from deprived areas of Nottingham, which is one of the most deprived cities in the UK. The study employs Interpretative Phenomenological Analysis (IPA) to consider each entrepreneurial endeavour as a unique journey to investigate the shifting of motivations.
Findings
A polarization is found in terms of how entrepreneurial motivations evolve in deprived areas. In considering the first task-specific entrepreneurial motivation, time plays a role either in accumulating job dissatisfaction and increasing confidence led by accumulated experience, or in creating random chances that enable individuals to realize that they are able to use existing skills and experiences to start a business. Regarding the second task-specific entrepreneurial motivation when the business becomes more established, it is usually stimulated by increased confidence based on perceived progress. The use of self-help methods and downward comparison found in this study should be noted as they help to re-consider individuals' needs in deprived areas.
Originality/value
This study produces a more comprehensive understanding of the phenomenon of the time effect on shifted motivation at different entrepreneurial phases in a deprived context, which contributes to enrich theoretical knowledge and raise policymakers' awareness of entrepreneurial motivations from these marginalized groups.

Abstract
Studies have suggested that entrepreneurship is a key mechanism for rejuvenating and facilitating economic growth in deprived areas. To provide further understanding of the persistently low entrepreneurial intentions found in deprived areas this chapter identifies key mechanisms and theoretical frameworks that link the formation of appropriate human capital to the prevailing environment, and that influences may flow in both directions. This contributes to the existing literature to provide a fuller understanding of interest to policy-makers of why past interventions have struggled to boost entrepreneurial intentions and where new interventions may be most effective in generating more positive entrepreneurial intentions in deprived areas.

Abstract
Purpose
This paper aims to realize an in-situ quality inspection system rapidly for new injection molding (IM) tasks via transfer learning (TL) approach and automation technology.
Design/methodology/approach
The proposed in-situ quality inspection system consists of an injection machine, USB camera, programmable logic controller and personal computer, interconnected via OPC or USB communication interfaces. This configuration enables seamless automation of the IM process, real-time quality inspection and automated decision-making. In addition, a MobileNet-based deep learning (DL) model is proposed for quality inspection of injection parts, fine-tuned using the TL approach.
Findings
Using the TL approach, the MobileNet-based DL model demonstrates exceptional performance, achieving validation accuracy of 99.1% with the utilization of merely 50 images per category. Its detection speed and accuracy surpass those of DenseNet121-based, VGG16-based, ResNet50-based and Xception-based convolutional neural networks. Further evaluation using a random data set of 120 images, as assessed through the confusion matrix, attests to an accuracy rate of 96.67%.
Originality/value
The proposed MobileNet-based DL model achieves higher accuracy with less resource consumption using the TL approach. It is integrated with automation technologies to build the in-situ quality inspection system of injection parts, which improves the cost-efficiency by facilitating the acquisition and labeling of task-specific images, enabling automatic defect detection and decision-making online, thus holding profound significance for the IM industry and its pursuit of enhanced quality inspection measures.

Abstract
Purpose
This paper aims to investigate the effect of frictional heat on the wear of high-speed rotary lip seals in engines.
Design/methodology/approach
In this research paper, the authors focus on the high-speed rotating lip seal of aircraft engines. Using the hybrid lubrication theory, a thermal-fluid-solid coupled numerical simulation model is established to investigate the influence of parameters such as contact pressure distribution, temperature rise and leakage rate on the sealing performance under different operating conditions. By incorporating the Rhee wear theory and combining simulation results with experimental data, a method for predicting the wear of the rotating seal lip profile is proposed. Experimental validation is conducted using a high-speed rotating test rig.
Findings
The results indicate that as the speed increases, the rise in frictional heat leads to a decrease in the sealing performance of the lip seal contact region. The experimental results show a similar trend to the numerical simulation results, and considering the effect of frictional heat, the predicted wear of the lip seal profile aligns more closely with the actual wear curve. This highlights the importance of considering the influence of frictional heat in the analysis of rotating seal mechanisms.
Originality/value
This study provides a reference for the prediction of wear profiles of engine high-speed rotary lip seals.

Abstract
This study explores the characteristics of high-speed rail (HSR) and air transportation networks in China based on the weighted complex network approach. Previous related studies have largely implemented unweighted (binary) network analysis, or have constructed a weighted network, limited by unweighted centrality measures. This study applies weighted centrality measures (mean association [MA], triangle betweenness centrality [TBC], and weighted harmonic centrality [WHC]) to represent traffic dynamics in HSR and air transportation weighted networks, where nodes represent cities and links represent passenger traffic. The spatial distribution of centrality results is visualized by using ArcGIS 10.2. Moreover, we analyze the network robustness of HSR, air transportation, and multimodal networks by measuring weighted efficiency (WE) subjected to the highest weighted centrality node attacks. In the HSR network, centrality results show that cities with a higher MA are concentrated in the Yangtze River Delta and the Pearl River Delta; cities with a higher TBC are mostly provincial capitals or regional centers; and cities with a higher WHC are grouped in eastern and central regions. Furthermore, spatial differentiation of centrality results is found between HSR and air transportation networks. There is a little bit of difference in eastern cities; cities in the central region have complementary roles in HSR and air transportation networks, but air transport is still dominant in western cities. The robustness analysis results show that the multimodal network, which includes both airports and high-speed rail stations, has the best connectivity and shows robustness.
