Planning for underground spaces has become an effective way to use central areas in cities given the steady economic growth in China. The development of underground spaces in mountainous cities has satisfied the needs of the diversification of the city commercial areas and pedestrian movement. Safety issues exist because these underground spaces were originally used for civil air defense. This study was based on the underground commercial street in Chongqing, which is a typical mountainous city. Based on the results of combined fieldwork and survey, this paper summarized current safety issues, which include the not-fully-open exit, the imbalanced exit location, blocked evacuation routes, and the poor awareness of the potential safety issues. This paper proposed a framework of the safety factors for the underground space and synopsized prevention strategies that are specific to potential disasters in the underground environment. The framework comprises ensuring that the exits are fully open, the underground corridors are kept unblocked, the open space on the street is increased for disaster prevention, and equipment security is maintained and managed. At last, This paper summarized disaster prevention strategies, which include ensuring unimpeded exits, balancing the locations of the exits, avoiding blocks, increasing the disaster prevention square area in the underground space, maintaining and managing the security of the equipment.

Due to the rapid urbanization in China, the living environment in urban areas improves considerably, while that in rural settlements does not improve remarkably, or even worsens. The purpose of the research is to propose an organizational approach to the improvement of the living environment in the poverty-stricken rural settlements and an architectural design pattern under a variety of requirements in the context of China’s rapid urbanization and socio-economic development in the redevelopment of rural settlements in Yongsheng Village, Lizhuang Town, Yibin City of Sichuan Province in Southwest China. In this redevelopment project, the architects, as the important third party, are not just architects in the traditional sense in that they are involved in the organizational process and architectural design throughout the whole project. The redevelopment project has been completed, and is aimed at providing a scientific redevelopment model and a design method for other rural residents by guiding them in the improvement of their living environment under a variety of restrictions.

The purpose of this paper is to examine issues academics at importing institutions face while delivering Australian degrees in Malaysia. Transnational higher education (TNE) has been widely researched. However, less widely researched is the area of understanding what academics at the offshore locations need to uphold the required academic standards of their partnered exporting universities. This area warrants close attention if Australian and other transnational education universities are to sustain their growth through a partnership model with offshore academics delivering a portion (often a substantial portion) of the teaching.

Two focus groups were conducted with a mix of long standing and newly recruited Malaysian lecturers who taught into an Australian degree through a partnership arrangement. The semi-structured questions which were used were derived from a preliminary literature review and previous internal institutional reports.

The findings from the focus groups indicate that TNE is largely “Australian-centric” when addressing the standard of academic quality and integrity. The findings pointed not so much to any sustained internationalisation of curriculum or administration or personnel but more as internationalisation as deemed required by the local academic.

To a greater extent, the findings highlighted that equivalent student outcomes do not necessarily equate to equivalent learning experiences or teaching workload. In fact, the frustration of the interviewees on the tension to fulfil the home institution curriculum and helping students to “comprehend” an Australian-centric curriculum translates to “additional and unrecognised workload” for the interviewees.

The purpose of this study is to discover and model the asymmetry in the price volatility of financial markets, in particular the foreign exchange markets as the first underlying applications.

The volatility of the financial market price is usually defined with the standard deviation or variance of the price or price returns. This standard definition of volatility is split into the upper part and the lower one, which are termed here as Yang volatility and Yin volatility. However, the definition of yin‐yang volatility depends on the scale of the time, thus the notion of scale space of price‐time is also introduced.

It turns out that the duality of yin‐yang volatility expresses not only the asymmetry of price volatility, but also the information about the trend. The yin‐yang volatilities in the scale space of price‐time provide a complete representation of the information about the multi‐level trends and asymmetric volatilities. Such a representation is useful for designing strategies in market risk management and technical trading. A trading robot (a complete automated trading system) was developed using yin‐yang volatility, its performance is shown to be non‐trivial. The notion and model of yin‐yang volatility has opened up new possibilities to rewrite the option pricing formulas, the GARCH models, as well as to develop new comprehensive models for foreign exchange markets.

The asymmetry of price volatility and the magnitude of volatility in the scale space of price‐time has yet to be united in a more coherent model.

The new model of yin‐yang volatility and scale space of price‐time provides a new theoretical structure for financial market risk. It is likely to enable a new generation of core technologies for market risk management and technical trading strategies.

This work is original. The new notion and model of yin‐yang volatility in scale space of price‐time has cracked up the core structure of the financial market risk. It is likely to open up new possibilities such as: a new portfolio theory with a new objective function to minimize the sum of the absolute yin‐volatilities of the asset returns, a new option pricing theory using yin‐yang volatility to replace the symmetric volatility, a new GARCH model aiming to model the dynamics of yin‐yang volatility instead of the symmetric volatility, new technical trading strategies as are shown in the paper.

This study investigates the influence of paradoxical leadership on employee transformative learning in higher education institutions (HEIs). Based on paradox theory, this research examines how a paradoxical mindset mediates this relationship and explores the moderating role of employees’ moral values in developing a paradoxical mindset and fostering transformative learning.

The research adopted a quantitative approach. In three phases, data were collected from 411 randomly selected faculty members of HEIs in Pakistan to assess their perceptions of paradoxical leadership, followers’ paradoxical mindset, moral values and transformative learning outcomes. Structural equation modeling was employed for analysis in AMOS26.

The findings reveal paradoxical leadership’s positive and significant impact on transformative learning, mediated by developing a paradoxical mindset. Moral values positively moderate the relationship between paradoxical leadership and developing a paradoxical mindset. However, the moderating effect of moral values on the link between a paradoxical mindset and transformative learning was insignificant.

The study suggests that organizations, particularly HEIs, should cultivate paradoxical leadership to navigate inherent tensions and contradictions, fostering an environment conducive to transformative learning. Developing a paradoxical mindset among employees is crucial for enhancing adaptability and learning, with moral values playing a pivotal role in amplifying the effectiveness of paradoxical leadership.

This study contributes to the literature by providing empirical evidence on the mechanism through which paradoxical leadership influences transformative learning. It extends paradox theory to the context of transformative learning, highlighting the importance of cognitive and ethical dimensions in leadership and learning processes within HEIs.

The purpose of this paper is to determine the influence and interaction of social networks and personality traits on the self-disclosure behavior of social network site (SNS) users. According to social capital theory and the Big Five personality model, the authors hypothesized that social capital factors would affect the accuracy and amount of self-disclosure behavior and that personality traits would moderate this effect.

A survey was conducted to collect data from 207 SNS users. The questionnaire was administered in university classrooms and libraries and via e-mail. The measurement model and structural model were examined by using LISREL 8.8 and SmartPLS 2.0.

Based on the path analysis, the authors identified several interesting patterns to explain self-disclosure behavior on SNSs. First, the centrality of SNS users has a positive effect on their amount of self-disclosure. Moreover, people who are more extroverted disclose personal information that is more accurate with the level of the cognitive dimension held constant and disclose a greater amount of personal information with the level of the structural dimension held constant. From a practical perspective, the results may provide useful insight for companies operating SNSs.

This study analyzed the influence of social capital factors on SNS users’ self-disclosure, as well as the interactions between personality and social capital factors. Specifically, the authors examined six important variables of social capital divided into three dimensions. This research complements current research on SNSs by focusing on SNS users’ motivation to disclose self-related information in addition to information sharing.

Despite the importance of platform digitization capability to established firms, empirical research related to platform digitization capability, resource reconfiguration and organizational resilience remains scarce. Based on resource action view and contingency theory, this study constructs an integrated theoretical framework to examine the mediation effect of resource reconfiguration and the moderation effect of environmental munificence in the relationship between resource reconfiguration and organizational resilience.

Survey data comprising 312 valid responses are collected from manufacturing firms in China. Partial least squares equation modeling (PLS) was used in this study to test the hypotheses.

Results showed that platform digitization capability is positively related to organizational resilience. Resource recombination and resource reallocation mediate the platform digitization capability–organizational resilience relationship. Furthermore, environmental munificence significantly strengthens the relationship between resource recombination and organizational resilience while weakens the relationship between resource reallocation and organizational resilience.

This study reveals the path of platform digitization capability affecting organizational resilience, discusses the different role of resource recombination and resource reallocation and makes incremental contributions to resource action view. It also studies the impact of resource reconfiguration on organizational resilience under the condition of environmental munificence, which provides a new perspective for the study of organizational resilience and enriches the application of contingency theory in the crisis context.

Considering the external disturbances and dynamic uncertainties during the process of the trajectory tracking, this paper aims to address the problem of the welding robot trajectory tracking with guaranteed accuracy.

The controller consists sliding mode control, fuzzy control and low pass filter. The controller adopts low-pass filter to reduce the high frequency chattering control signal in sliding mode control. The fuzzy control model is used to simulate the external disturbance signal and the dynamic uncertainty signal, so that the controller can effectively restrain the chattering caused by the sliding mode control algorithm, realizing the track of the welding robot effectively and improving the robustness of the robot.

An innovative experiment device was adopted to realize the performance of the proposed controller. Considering the kinematic and dynamic uncertainty during the process of robot tracking, the tracking accuracy was realized within 0.3 mm.

This paper uses Lyapunov stability theory and Barbalat theorem to analyze the stability of the proposed controller.

This paper aims to examine the internal logical relationship between two intergenerational inheritance ways of passing property rights and residual control rights (RCR) and to construct a conceptual model comprising transfer elements, paths and timing of succession in this process.

Driven by the cases of Haixin, Tianyijiao and Changhe Group, this paper applies research methods of copying and expanding analysis logic, progressive deduction, content analysis and comparative research based on the perspective of HeXie theory to explore the deep interrelation of transfer elements, paths and timing during family business succession.

The findings present that the content of intergenerational inheritance of a family firm is the inheritance of property rights and RCR. First, the inheritance of property rights is a static inheritance of time-point delivery, whereas the inheritance of RCR is a dynamic inheritance process for a period of time. Second, the inheritance of property rights and RCR are not independent; only a “HeXie” succession of both rights can realize a successful inheritance of family firms.

This paper constructs the paths and timing model of intergenerational inheritance of property rights and RCR in family firms. This paper integrates the current literature studies on the family inheritance of property rights and RCR and explains their internal mechanisms. This paper also provides a theoretical foundation and empirical evidence for family business transitions in the business world.

For the purpose of saving nickel, this study aims to develop new duplex stainless steel cored wires suitable for wire arc additive manufacturing (WAAM) with the addition of nitrogen.

The effect of nitrogen content on the microstructure and mechanical properties of the thin-walled deposits is investigated in detail.

The microstructure of thin-walled deposits mainly consists of austenite, ferrite and secondary austenite. With increasing nitrogen content, the austenite in the deposited metals increases. The austenite proportion in the bottom region is more than that in the top region of the deposited metals. The χ phase is randomly distributed at the grain boundaries and within ferrite. The σ phase is mainly precipitated at ferrite and austenite grain boundaries. With increasing nitrogen content, the tensile strength of the deposited metals increases, but the impact toughness of the deposited metals deteriorates.

This study proposes new duplex stainless steel cored wires for WAAM, which realizes the objective of saving nickel.
