The safety and reliability of high-speed trains rely on the structural integrity of their components and the dynamic performance of the entire vehicle system. This paper aims to define and substantiate the assessment of the structural integrity and dynamical integrity of high-speed trains in both theory and practice. The key principles and approaches will be proposed, and their applications to high-speed trains in China will be presented.

First, the structural integrity and dynamical integrity of high-speed trains are defined, and their relationship is introduced. Then, the principles for assessing the structural integrity of structural and dynamical components are presented and practical examples of gearboxes and dampers are provided. Finally, the principles and approaches for assessing the dynamical integrity of high-speed trains are presented and a novel operational assessment method is further presented.

Vehicle system dynamics is the core of the proposed framework that provides the loads and vibrations on train components and the dynamic performance of the entire vehicle system. For assessing the structural integrity of structural components, an open-loop analysis considering both normal and abnormal vehicle conditions is needed. For assessing the structural integrity of dynamical components, a closed-loop analysis involving the influence of wear and degradation on vehicle system dynamics is needed. The analysis of vehicle system dynamics should follow the principles of complete objects, conditions and indices. Numerical, experimental and operational approaches should be combined to achieve effective assessments.

The practical applications demonstrate that assessing the structural integrity and dynamical integrity of high-speed trains can support better control of critical defects, better lifespan management of train components and better maintenance decision-making for high-speed trains.

An important but much neglected aspect of service quality is integrity. Discusses the nature and benefits of service integrity. Begins by discussing what service integrity is and why it is important. Describes and discusses integrity breakdowns and the business benefits of service integrity. Concludes with some guidelines on how to manage service integrity and suggestions for further research.

The authors propose that international organizational leaders can and should be held accountable for enhancing the intangible strategic asset of integrity capacity in order to advance global organisational excellence. After defining integrity capacity and framing it as part of a strategic resource model of sustainable global competitive advantage, the stakeholder costs of integrity capacity neglect are delineated. To address this neglect issue, the authors link the four dimensions of integrity capacity (process, judgment, development and system dimensions) with leadership development challenges, and recommend four management practices to better prepare leaders to be accountable for enhancing integrity capacity as a strategic organizational asset.

The purpose of this paper is to examine what is meant by integrity and attempts to translate the concept into specific behaviors that can be taught and learned.

Highlights the topicality of integrity and shows why it is likely to become increasingly important in organizations.

Presents four basic leadership‐integrity behaviors – moral purpose, lawful and ethical, consistency and standing for something. Highlights the importance of discerning what is right and wrong, acting on what one has discerned, even at personal cost, and saying openly that one is acting on what one understands to be right or wrong.

Advances commercial arguments for developers to espouse and promote integrity and the importance of learning about it in their organizations. Shows that integrity underpins an organization's ultimate profitability and competitiveness, as well as increasing employees' pride, engagement with their jobs and customer loyalty. Claims that integrity has also been revealed to enhance company brand or reputation, improve efficiency, attract staff, conserve and sustain resources and mitigate business risk.

Emphasizes that, in communicating the need to focus on integrity and offering ways to help leaders to develop their performance in this area, it makes sense to focus on what is productive for both the individual and the organization.

Deterioration of integrity is featured in public service across the globe, including Tanzania. Local government authorities (LGAs) are among the areas where such practices have been reported. However, factors compromising integrity in LGAs receives less attention from the literature. Citing 19 LGAs from Tanzania, this study aims to examine contributes to this debate.

A sequential explanatory research design was applied. Data were collected from 54 respondents through survey questionnaires, interviews and a documentary review. The study was guided by Hoekstra theoretical framework for assessing integrity practices in LGAs.

The findings revealed that maintaining integrity in Tanzania's LGAs is still challenging. Poor institutionalization processes, institutional unpreparedness, insufficient integrity policy execution and being less informed of moral development of recruited public servants are said to compromise integrity in Tanzania LGAs. This qualifies to conclude that institutional pathologies and moral history of public servants are the major factors contributing to integrity deterioration in Tanzania LGAs. This has resulted in subpar service delivery and the waste of public funds.

This study confined itself to Tanzania LGAs. More studies could be conducted to LGAs in other countries struggling with the same problem. On the same ground, moral development should be studied more to ensure that the public service receives ethical public servants in the future.

The theoretical framework for assessing integrity systems in LGAs as proposed by Hoekstra (2022) could be applied by other countries struggling with the same challenge.

LGAs must implement an integrity-based self-reflection technique that will allow them to assess their current condition and come up with solutions. Furthermore, institutional policies must be strengthened to govern ethical behavior in LGAs.

In this study, the authors consider the mediating role of psychological capital (i.e. PsyCap) in the relationship between integrity and academic performance. Specifically, the authors propose that integrity is a relatively stable and distal character strength that is likely to have a minimal direct effect on academic performance. Going further, the authors argue that integrity is more likely to have an indirect effect on academic performance via the psychological resources that encompass one's PsyCap.

Drawing from a sample of 179 undergraduate business students and student grade point average (GPA) data, the authors find support for the notion that PsyCap partially mediates the relationship between integrity and academic performance.

These findings reveal the key role that PsyCap plays in translating a student's integrity toward behaviors that lead to higher levels of academic performance.

Prior research suggests the direct relationship between integrity and academic performance has been mixed. In this study, the authors consider how mediation may help explain this relationship. The authors believe this to be among the first empirical studies to consider integrity, PsyCap and academic performance.

This study aims to investigate the effect of leadership integrity on employees’ success. In this regard, the mediating role of ethical leadership and the moderating role of psychological capital and psychological empowerment were considered as well.

This study is an applied research and a descriptive-correlation survey that used quantitative data. Data were collected from 302 employees of a large factory in Iran who was selected randomly. The research questionnaire consisted of 54 statements and was distributed among the sample. Data was analyzed through confirmatory factor analysis and structural equation modeling.

The findings of this study show that leader integrity and ethical leadership have a positive effect on employees’ success and psychological capital and psychological empowerment moderate these effects. Moreover, leader integrity has an indirect effect on employees` success through employees’ perception of ethical leadership.

This study mainly contributes by explaining two sets of variables related to leaders’ behavior and employees’ cognitive competence which are complementary in improving employees’ potential success. The results highlight that leaders’ behavioral integrity can amplify ethical leadership which can ultimately leads to employees’ success if they have a high psychological empowerment and psychological capital.

The aim of this study is to look into the factors that influence the level of ethics and integrity in Malaysian public sector.

This study uses a quantitative approach by delivering 128 questionnaires to Federal Chief Integrity Officers (CIOs), of which 83 were received and usable. The data were analysed using multiple regression analysis and descriptive statistics.

The quality of CIO in terms of competency, work performance and ethical climate has significant impact on the level of ethics and integrity. According to the study, having certified CIOs who can effectively perform their function and promote and nurture a transparent ethical climate are critical for the Malaysian Federal government to maintain a high level of ethics. Employees who have a high level of ethics are more likely to stay with the organization.

In addition, this study will assist policymakers in taking the required actions to strengthen public sector integrity practices for the establishment of a more dependable and efficient government in Malaysia.

This study addresses a gap in the Malaysian public sector’s level of ethics and integrity.

This paper aims to evaluate the effects of fraud risk elements and integrity on asset misappropriation in the Royal Malaysian Police (RMP). In addition, this research also examines whether integrity moderates the relationship between fraud risk elements and asset misappropriation.

Data are gathered from the responses of the questionnaires distributed to the RMP. A total of 200 questionnaires were distributed based on simple random selection from five RMP centres in the capital city. Out of 200 questionnaires distributed, only 189 were returned.

The findings indicate that the existence of fraud risk elements significantly affects the incident of asset misappropriation. An interesting finding was made that integrity is negatively related to asset misappropriation. This implies that integrity is an important value in minimising the occurrence of asset misappropriation. The results also indicate that minimising fraud risk elements is crucial in reducing the incident of asset misappropriation.

This present paper contributes to the literature by investigating a commonly proposed but underexplored elements of integrity in mitigating fraud. Incorporating integrity and fraud risk elements simultaneously in a single framework in context of RMP would enhance the understanding and will be able to provide a framework for practitioners on how to mitigate the incident of fraud.

The purpose of this paper is to develop an integrity monitoring method using ERAIM (Extended Receiver Autonomous Integrity Monitoring) for the integrated GNSS/Inertial (Global Navigation Satellite System and inertial navigation system) of general aviation aircraft.

First the tightly integrated GNSS with Strapdown Inertial Navigation System (GNSS/SINS) and the Kalman filter is designed. Then the processing of ERAIM is presented, in which the least‐squares theory is used to calculate the best estimators by integrating the predicted states with measurement states of Kalman filter. Based on the new measurement model, the integrity monitoring for GNSS/inertial system is carried out, including the fault detection, identification, reliability and separability. Lastly, the simulation and analysis for ERAIM vs RAIM are performed to validate the proposed method.

Simulation results show that the ERAIM method is able to detect and identify effectively any type of failure including step failure and ramp failure. Compared to the RAIM method for only GNSS, the ERAIM increases the redundant information and reduces the correlation of test statistics, as well as enhancing the reliability and thus can significantly improve the performance of integrity monitoring.

In safety critical sectors such as aviation, stringent integrity performance requirements must be met. The ERAIM method cannot only be used in integrity monitoring for the integrated GNSS/Inertial system, but also can be applied to only GNSS or other integrated navigation systems for general aviation aircraft.

The paper presents a new integrity monitoring method of ERAIM, which is able to improve the fault detection and identification capabilities significantly by extending GNSS‐used RAIM method into the GNSS/Inertial integrated system.
