    Essays on corporate social responsibility : a thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Finance, School of Accountancy, Economics and Finance, Massey University
    (Massey University, 2025-09-18) Zhang, Xiaochi
    This thesis comprises three essays advancing the literature on workplace safety, an important component of corporate social responsibility. The first essay examines how generalist CEOs with transferable managerial skills enhance workplace safety. These executives improve safety by optimizing labor investments, reducing employee workloads, and ensuring higher information quality. The relation is more pronounced among firms facing financing constraints or intense market competition. The study also shows that workplace injuries and illnesses reduce innovation, productivity, and firm value. The second essay explores the impact of shareholder distraction on workplace safety. Distracted shareholders are linked to higher rates of work-related injuries, especially in firms with weak governance and high competition risks. Our findings suggest that reduced monitoring by distracted shareholders leads to lower safety investments, increased workloads, and greater earnings management, resulting in a poorer safety environment. The third essay investigates how the inclusion of general counsel in top management improves employee safety. Firms with general counsel in senior leadership are associated with lower injury and illness rates. The relation is more pronounced for firms with better information quality, more efficient labor investment, leadership by lawyer CEOs, weaker governance structures, and heightened agency problems. Overall, these essays provide new insights into how corporate leadership and governance influence workplace safety. The thesis offers contributions to the literature on workplace safety by addressing critical gaps in existing research. This work extends theoretical frameworks such as upper echelon theory by applying it to the domain of workplace safety. It also underscores the practical implications of aligning leadership capabilities and governance mechanisms to safeguard human capital, ultimately driving sustainable firm performance.

    Adopting augmented reality to avoid underground utilities strikes during excavation : a thesis submitted in fulfilment of the requirements for the degree of Doctor of Philosophy, School of Built Environment, College of Science, Massey University, New Zealand
    (Massey University, 2025) Khorrami Shad, Hesam
    The construction industry constantly pursues innovative methods to improve safety, enhance productivity, and reduce costs and project durations. Augmented Reality (AR) is a promising technology, potentially bringing about transformative changes in construction. AR is a promising technology for visualizing data in construction sites and preventing clashes and accidents. One of its promising applications is in the excavation sector, where accidental strikes on underground utilities pose serious safety risks, delays, and costly damages. However, while AR has gained increasing attention in recent years, its integration into construction practice remains limited. To address this limitation, this research investigates the potential of AR to facilitate identifying underground utility locations through a systematic review, industry engagement, and user-centred experimentation. Initially, a systematic literature review was conducted to explore the current applications of AR in construction safety. This review identified the safety purposes of AR across three project phases: pre-event (e.g., training, safety inspections, hazard alerting, enhanced visualization), during-event (e.g., pinpointing hazards), and post-event (e.g., safety estimation). However, the review also revealed a notable lack of studies focused on AR applications in excavation activities, particularly for underground utility strike prevention. In response, a study was undertaken to understand the needs, expectations, and challenges associated with adopting AR in the excavation sector. 31 professionals from the excavation industry participated in the within-subject experiment, interacting with two AR prototypes, delivered via Optical See-Through (OST) and Video See-Through (VST) devices. The findings indicated a clear preference for AR over traditional methods such as paper-based drawings. Participants showed a preference for VST rather than OST, given their familiarity with VST devices such as tablets. Further, accessibility emerged as the primary barrier to adopting AR within the excavation industry. Building on the literature and industry insights, an experimental study was designed to evaluate the effectiveness of different AR visualization methods in underground utility detection. A within-subject experiment involving 60 participants was conducted to compare four of the most cited visualization techniques for underground utilities: X-Ray, Shadow, Cross-Sectional, and a newly developed Combination method. Drawing on the Theory of Affordances and Task Load analysis, the study found that the Combination and X-Ray visualization methods perform superior to the Shadow. These results provide empirical support for the user-centered design of AR visualization techniques in excavation practice. This research contributes to the fields of human-computer interaction, construction safety, and digital technology adoption by advancing the use of AR for underground utility strike prevention. The study shifts the focus of AR from general safety training to real-time, spatial visualization for excavation, offering both theoretical insights and practical applications. Methodologically, it follows a structured mixed-methods approach, combining literature review, industry engagement, and experimental testing. Practically, it identifies user preferences, visualization methods, and key adoption factors such as usability and accessibility. Overall, this thesis fills the gap between emerging AR technologies and their integration into safer excavation practices.

    The interface between ethical leadership and food safety culture in Aotearoa New Zealand food businesses : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy, School of Management, Massey University, Palmerston North, New Zealand
    (Massey University, 2025-05-20) Newport-Smith, Wendy
    Measuring, evaluating and improving food safety culture is a priority for Aotearoa New Zealand food businesses. This is driven by the desire to produce food of the highest quality that safeguards consumers, protects the reputation of New Zealand Inc., and meets the requirements of international standards and regulations. This is the first in-depth qualitative investigation into food safety culture and ethical leadership in Aotearoa New Zealand food businesses, including some of this country’s largest food exporters. Using a mixed methods approach this research has provided unique, contemporary understanding and insights, while simultaneously providing a novel contribution to the body of knowledge. Two research workstreams were used; the first a quantitative workstream involving a voluntary survey of manufacturing and distribution employees in New Zealand’s largest food business; a dataset of responses to food safety and ethical leadership questions from 1181 individuals. Using Principal Component Analysis (PCA) applied to Lickert-scale variables, combined with multivariable modelling, this research found a positive relationship between food safety culture and ethical leadership and evidence for differences in responses according to several respondee characteristics. These included associations between PCA coordinates that captured variation in individual responses to food safety and ethical leadership questions, and the supplementary variables: role (e.g. staff or supervisor), site and gender. Ethical leadership has been shown to improve effectiveness, performance and safety at an organisational and individual level. Therefore strategies to improve ethicality across Aotearoa New Zealand food businesses in order to improve food safety culture and ensure safer food outcomes are suggested: consultatively developing organisational values which are well communicated and lived; ensuring ethical considerations when hiring staff; ethical considerations when setting expectations, and in training and mentoring staff and managing performance processes including the use of consequences; and modelling good behaviour, making fair decisions, ensuring open, clear communication and giving employees a voice. While largely positive, the quantitative strand did reveal a level of dissatisfaction with both ethical leadership and food safety culture, suggesting room for improvement. Further research is needed to better understand management’s, supervisors’ and workers’ perspectives on both aspects. The second workstream involved one-on-one semi-structured interviews with 32 founders, owners and senior food safety and quality personnel from 31 Aotearoa New Zealand food companies with thematic data analysis resulting in five key themes: Values; Responsible Stewardship of Natural Resources; Māori Worldview; Ecosystem Pressures and Leadership. The issues identified to be important to Aotearoa New Zealand food businesses include: individual, managerial and organisational values; leadership and management commitment in influencing organisational, food safety and ethical climate and culture; inter-generational value-creation, sustainable practice and acting as kaitiakitanga meaning guardianship or protection. This research has also provided insight into the drivers for and primary challenges related to food safety for Aotearoa New Zealand food businesses. This research has contributed to an up-to-date understanding of the characteristics of ethical leaders in Aotearoa New Zealand, who, according to this study, are humble, honest, respect indigenous Māori values, and are not corrupt. They have a degree of relatedness, care about our natural environment, have a strong sense of identity or place, are collaborative, are fair, and are accountable. Our size, Indigenous Māori worldview, and our geographical isolation contribute to the unique interpretation and application of these leadership characteristics in Aotearoa New Zealand. Several limitations are acknowledged, not the least of which was the context for this research which began at the outset of the global pandemic, with both positive and negative consequences. The use of one, albeit large food business in the quantitative workstream is noted, as is the focus of the participants in the qualitative workstream. Broadening this research to all hierarchical levels in several food businesses would be of benefit, and this is one of a number of research recommendations for the future. The positive correlation between ethical leadership and food safety culture found in this research suggests that maintaining and improving the ethicality of leaders within Aotearoa New Zealand food businesses may positively influence food safety culture and therefore, the production of safer food.

    Digital vs paper-based checklists in high performance single pilot aircraft : a mixed methods investigation : a 190.895 (60 credit) research report presented in partial fulfilment of the requirements for the degree of Master of Aviation at Massey University, Palmerston North, New Zealand
    (Massey University, 2022) Barron, Peter
    The aircraft checklist has been described as the most critical man-machine interface in aviation. Checklists can significantly enhance flight safety when designed well and used properly. The ‘look’ and content of a checklist affects how well pilots interact with it. Emergency checklists in particular, are only accessed during emergency situations, a time of heightened stress and cognitive degradation for the pilot. It is crucial therefore, that emergency checklists are developed with precision and skill to facilitate ease of use during times of stress. A poorly designed checklist can hinder rectification of an emergency situation and can adversely affect flight safety. The aim of this study was to determine whether flying performance is improved, and pilot workload is lower, when using a digital checklist application created specifically for the T-6C Texan II compared with the existing paper-based Quick Reference Handbook (QRH). For this study, twenty pilots from the Royal New Zealand Air Force (RNZAF) underwent two emergency scenarios in a flight simulator using either the QRH or the digital checklist application. The independent variable was checklist type (paper or digital). Dependent variables were: i) time to find the checklist; ii) time to complete the checklist; iii) flight path accuracy; and iv) workload. Additionally, a qualitative investigation into error occurrences during checklist execution was undertaken. The results suggested that workload is lower when using the digital checklist application compared to the QRH, but there were mixed results regarding the improvement in flying performance with the digital checklist application. The time to find the checklist was quicker with the digital application, but checklist completion times and flight path accuracy were similar across both checklist types. The qualitative investigation noted that the digital checklist reduced errors and was easier to manipulate. The collection of qualitative data enabled the generation of a hypothesis that frequency and type of error occurrences are affected by checklist type. Despite the interface improvements of the digital checklist over the QRH, this research suggests that an enhanced checklist interface is secondary to checklist location or checklist content, and that the greatest gains in safety will likely be achieved by addressing these two factors over checklist interface. This research provides support for an iPad mount in front of the pilot in the T-6C. Additionally, this research provides further evidence that the T-6C checklist content is poorly written and can negatively impact flight safety and may assist in arguing for a content re-write. From a wider perspective, most RNZAF pilots fly with a kneeboard and this research may be relevant for other aircraft types operated by the RNZAF, noting also that other aircraft types are flown by two pilots which may negate some of the findings in this research. Further research should standardise the placement of the checklist to fully determine the relationship between flying performance and checklist type. Additionally, future research could also make use of eye tracking equipment to measure attention switching and could investigate the hypothesis generated from the qualitative data.

    Slot n' Slide : a concept design for a life jacket for flood events in India : an exegesis presented in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Design at Massey University, Wellington, New Zealand
    (Massey University, 2022) Shaik, Areef
    India endures numerous flood events every year due to its tropical monsoon climate. River delta regions affected by these disaster events are often heavily populated and experience considerable damage and loss of life through drowning. The life jacket currently in use by first responders in India negatively impacts performance with unsatisfactory levels of protection, comfort, and stowage. In addition, these products present fit and usability challenges and lack cultural sensitivity to end-users. This research project addresses the suitability of this life jacket to respond efficiently in an emergency by using a practice-led prototyping investigation to develop a specific flood rescue product that is reflective of the context of use and responsive to the cultural context of India. The outcome of this creative practice research is a ‘slot n slide’ panel life jacket inspired by the traditional Indian sari. This conceptual design accommodates a diverse range of body anthropometry in a one-size-fits-all solution, achieved by an innovative inter-panel strapping system with integrated side adjustments. This concept provides new and perceivable benefits, including improvements in utility for first responders, single product deployment, efficient stowage and provisioning with easier donning and doffing, broad size accommodation, and a single adjustment strap, improving usability for end-users.
