Accurately estimating the severity of derailment is a crucial step in quantifying train derailment consequences and, thereby, mitigating its impacts. The purpose of this paper is to propose a simplified approach aimed at addressing this research gap by developing a physics-informed 1-D model. The model is used to simulate train dynamics through a time-stepping algorithm, incorporating derailment data after the point of derailment.

In this study, a simplified approach is adopted that applies a 1-D kinematic analysis with data obtained from various derailments. These include the length and weight of the rail cars behind the point of derailment, the train braking effects, derailment blockage forces, the grade of the track and the train rolling and aerodynamic resistance. Since train braking/blockage effects and derailment blockage forces are not always available for historical or potential train derailment, it is also necessary to fit the historical data and find optimal parameters to estimate these two variables. Using these fitted parameters, a detailed comparison can be performed between the physics-informed 1-D model and previous statistical models to predict the derailment severity.

The results show that the proposed model outperforms the Truncated Geometric model (the latest statistical model used in prior research) in estimating derailment severity. The proposed model contributes to the understanding and prevention of train derailments and hazmat release consequences, offering improved accuracy for certain scenarios and train types

This paper presents a simplified physics-informed 1-D model, which could help understand the derailment mechanism and, thus, is expected to estimate train derailment severity more accurately for certain scenarios and train types compared with the latest statistical model. The performance of the braking response and the 1-D model is verified by comparing known ride-down profiles with estimated ones. This validation process ensures that both the braking response and the 1-D model accurately represent the expected behavior.

The technical report released by the National Transportation Safety Board, along with the primary flight cockpit voice recorder data and archival interview data, were used as the basis for this case. Other available public data such as news reports were used to round out the synopsis of the case study.

United Express Flight 5925 was a scheduled commuter passenger flight operated by Great Lakes Airlines with a Beechcraft 1900 twin turboprop. It was a regularly scheduled flight from Chicago O'Hare International Airport to Quincy, Illinois, with an intermediate stop in Burlington, Iowa. Drawing from various first-hand accounts (cockpit voice recorder) and secondary evidence (news reports, archival interview data, and online sources) of the tragedy, the case provides a detailed account of the key events that took place leading up to the accident at Quincy regional airport. The case describes how the radio interactions, a jammed door and degradation of situational awareness all contributed to the accident. Through many of the quotes in the text and eyewitness accounts, readers gain an understanding of the impressions and perceptions of the pilots, including how they felt about many of the critical decisions in the last minutes of the flight and the situation at the airport.

When the authors teach this case, the students are required to read it as pre-reading before class. Various readings and materials (see supplemental readings below and Exhibit 3) are made available to students before class, and the instructor can choose to use some of these materials to further explore areas of interest. This case is best explored over a 90-min session but could be expanded to take up one 3-h session. This case can be covered in an undergraduate senior capstone organizational behaviour seminar, any general organizational behaviour class (including introductory in nature), an undergraduate communication theory class or an MBA class that focuses on applied organizational behaviour concepts. It works particularly well in the MBA class, as students with work experience can make the links between the behaviours explored in the case and their everyday workplaces.

In this study, we illuminate how techniques can be incorporated into interview protocols when conducting research with educational leaders who are being asked to discuss their experiences in crises.

We interviewed seven researchers about their role as a researcher in collecting data on a crisis event from participants. Our analysis concentrated on several key components of the interview.

In presenting our findings on how scholars can adopt a caring and just approach to interview studies with leaders regarding crises, we portray how this approach can be melded into research design, interview protocol and interview techniques.

We illuminate that specific interview techniques are required when interviewing participants who have undergone and survived crises in their work, and we recommend the use of this protocol especially when an interview requires researchers to “handle with care.”

The digital age requires people of all ages to communicate and organise their lives through digital technologies. The project EQualCare investigates how the growing population of older people living alone is managing this transition, how it shapes their (non-)digital social networks and what changes on a local level need to be brought about. This paper aims to give insight into the process of participatory action research (PAR) with older people in the community across four countries and reflects on experiences made by academic and co-researchers.

Following the emancipatory underpinnings of PAR, which aims to reduce inequalities through collaboration and co-design, EQualCare involved nine teams of co-researchers across Finland, Germany, Latvia and Sweden making older people the centre of policy development. Co-researchers were involved in formulating research aims, collecting data, reflecting on data, formulating and disseminating recommendations for local policy stakeholders.

Co-researchers’ motivation to invest considerable time and effort was driven by a desire to create a more equal future for older people living alone. Moreover, they were keen to involve marginalised older people and became frustrated when this proved difficult. Power dynamics played a role throughout the process but became productive as roles and responsibilities were renegotiated. Doing PAR with older people can be emotionally challenging for co-researchers when negative feelings around ageing are encountered.

The paper advances understanding on the process of PAR in ageing research by reflecting on the social, cultural and political contexts of doing PAR with diverse sets of older people.

The crane plays an essential role in modern construction sites as it supports numerous operations and activities on-site. Additionally, the crane produces a big amount of data that, if analyzed, could significantly affect productivity, progress monitoring and decision-making in construction projects. This paper aims to show the usability of crane data in tracking the progress of activities on-site.

This paper presents a pattern-based recognition method to detect concrete pouring activities on any concrete-based construction sites. A case study is presented to assess the methodology with a real-life example.

The analysis of the data helped build a theoretical pattern for concrete pouring activities and detect the different phases and progress of these activities. Accordingly, the data become useable to track progress and identify problems in concrete pouring activities.

The paper presents an example for construction practitioners and researcher about a practical and easy way to analyze the big data that comes from cranes and how it is used in tracking projects' progress. The current study focuses only on concrete pouring activities; future studies can include other types of activities and can utilize the data with other building methods to improve construction productivity.

The proposed approach is supposed to be simultaneously efficient in terms of concrete pouring detection as well as cost-effective. Construction practitioners could track concrete activities using an already-embedded monitoring device.

While several studies in the literature targeted the optimization of crane operations and of mitigating hazards through automation and sensing, the opportunity of using cranes as progress trackers is yet to be fully exploited.

In this article, I explore how critical realism influenced the methods and methodology as well as the translations of interviews from Japanese into English and the interpretations of teachers’ understanding of the school at the center of this research.

This article investigates the interaction of critical realism within an English-language-based study of a Japanese high school using ethnographic methods and methodology and its influence on translations within the study. Critical realism combines a postpositivist ontological view with an epistemological constructionism. There is a reality to the school, which cannot be completely measured. This reality, the physical dimensions and composition (breadth, height, volume and number of classrooms) of the school, does not change based upon time or viewing location of an observer.

Critical realism provided strategies for and a focus on the translation of participant interviews from Japanese into English within this ethnographic study of a high school in Japan. These helped to provide a better understanding of the teachers' perception of the reality of the school.

This is original research.

The purpose of this study is to highlight and demonstrate how the study of stress and related responses in construction can best be measured and benchmarked effectively.

A range of perceptual and physiological measures are obtained across different time periods and during different activities in a fieldwork setting. Differences in the empirical results are analysed and implications for future studies of stress discussed.

The results of this study strongly support the use of multiple psychometrics and biosensors whenever biometrics are included in the study of stress. Perceptual, physiological and environmental factors are all shown to act in concert to impact stress. Strong conclusions on the potential drivers of stress should then only be considered when consistent results apply across multiple metrics, time periods and activities.

Stress is an incredibly complex condition. This study demonstrates why many current applications of biosensors to study stress in construction are not up to the task and provides empirical evidence on how future studies can be significantly improved.

To the best of the author’s knowledge, this is the first study to focus explicitly on demonstrating the need for multiple research instruments and settings when studying stress or related conditions in construction.

This chapter reports on research that explores new and emerging extended reality [XR] technologies and how they might provide opportunities to trial, investigate, and put into practice their potential to reverse processes of atomisation, polarisation, and intercultural discomfort, in our contemporary society. This transdisciplinary practice-led research was underpinned by disciplines of computer science and engineering, social sciences, history, diverse community economics, human ecology, and Indigenous psychology. The collaboration between these various disciplines with the Māori and non-Māori community members allowed researchers to understand current societal stressors, prioritise relationality, and explore our shared values in the creation of XR experiences for exhibition in the galleries, libraries, archives, and museums [GLAM] sector.

A discursive design framework motivated, inspired, provoked, persuaded, and reminded inspiring collaborators, and visitors to the exhibitions, the value of (re)connecting with people and overcoming interracial awkwardness through these curated experiences. The XR technologies provided women a platform to discuss and reimagine first encounters between people from different cultural backgrounds. The technologies included a 180° stereoscopic projection, Common Sense, in which Māori Elder Irene Hancy shared her insight about social engagement and haptic HONGI in which visitors were greeted by a Māori woman Tania Remana via augmented reality. This research has been motivated by a desire to promote and support intercultural understanding in Aotearoa New Zealand, and it extends research by other non-Māori and Māori scholars.

Concerns regarding the dysfunctional behaviours of public officials have sparked renewed interest in public service ethics and spirituality. While national and organizational systems have been established to eliminate dysfunctional behaviours such as corruption, sexual harassment and misuse of confidential information, the practice continues to have a demoralizing impact on developing countries. The study aims to intend to investigate the empirical relation between the application of spirituality and ethics in reducting dysfunctional behaviours within Ghana's Public Sector.

The study conducted a qualitative case analysis that utilized 28 semi-structured interviews and four focus groups. Interviews and group discussions with public sector staff, managers and policymakers were used to collect qualitative data. This approach facilitated an in-depth investigation into their views on dysfunctional actions and the possible impact of workplace spirituality and ethics in the Ghanaian public service.

The study uncovered a persistent recurrence of dysfunctional behaviours, such as fraudulent activities, resource misuse, unofficial work and inappropriate use of official time. There was uncertainty regarding the effectiveness of integrating ethics and spirituality to curtail dysfunctional behaviours. Nevertheless, the results supported adopting spiritual and ethical rejuvenation in the public service as a universal solution to overcome these behaviours.

This study enhances comprehension of dysfunctional behaviours in Ghana's public service by providing insights into how spirituality and ethics can transform it. The potentials of workplace spirituality and ethics can lead to a strong public service that embodies accountability, integrity and effectiveness, thereby serving as a pivotal device for Ghana's holistic advancement.
