The purpose of this paper is to realize the lightweight of connecting rod and meet the requirements of low energy consumption and vibration. Based on the structural design of the original connecting rod, the finite element analysis was conducted to reduce the weight and increase the natural frequencies, so as to reduce materials consumption and improve the energy efficiency of internal combustion engine.

The finite element analysis, structural optimization design and topology optimization of the connecting rod are applied. Efficient hybrid method is deployed: static and modal analysis; and structure re-design of the connecting rod based on topology optimization.

After the optimization of the connecting rod, the weight is reduced from 1.7907 to 1.4875 kg, with a reduction of 16.93%. The maximum equivalent stress of the optimized connecting rod is 183.97 MPa and that of the original structure is 217.18 MPa, with the reduction of 15.62%. The first, second and third natural frequencies of the optimized connecting rod are increased by 8.89%, 8.85% and 11.09%, respectively. Through the finite element analysis and based on the lightweight, the maximum equivalent stress is reduced and the low-order natural frequency is increased.

This paper presents an optimization method on the connecting rod structure. Based on the statics and modal analysis of the connecting rod and combined with the topology optimization, the size of the connecting rod is improved, and the static and dynamic characteristics of the optimized connecting rod are improved.

The OSCE is regarded as the gold standard of competence assessment in many healthcare programs, however, there are numerous internal and external sources of variation contributing to checklist marks. There is concern amongst organisers that candidates may be unfairly disadvantaged if they follow an “excellent” preceding candidate. This study assessed if average checklist scores differed depending on who a candidate follows accounted for different sources of variation.

This study examined assessment data from final year MBChB OSCEs at the University of Aberdeen and categorised candidates into three levels dependent on examiner awarded global scores of preceding candidates for each station. Data were modelled using a linear mixed model incorporating fixed and random effects.

A total of 349 candidates sat the OSCEs. The predicted mean (95% CI) score for students following an “excellent” candidate was 21.6 (20.6, 22.6), followed “others” was 21.5 (20.5, 22.4) and followed an “unsatisfactory” student was 22.2 (21.1, 23.3). When accounted for individual, examiner and station levels variabilities, students following an “excellent” candidate did not have different mean scores compared to those who followed “other” (p = 0.829) or “unsatisfactory” candidates (p = 0.162), however, students who followed an “unsatisfactory” student scored slightly higher on average compared to those who followed “other” (p = 0.038).

There was weak evidence that candidate's checklist variations could be attributed to who they followed, particularly those following unsatisfactory students; the difference in predicted mean scores may be of little practical relevance. Further studies with multiple centres may be warranted assuring perceived fairness of the OSCE to candidates and educators.

Based on social cognitive theory, this study aims to explore the influence of supervisor bottom-line mentality (SBLM) on employee knowledge behavior (knowledge territorial behavior and knowledge sabotage behavior). The study first investigates the role of an ethical decision-making mechanism (moral disengagement) in mediating this relationship. In addition, it considers the possible boundary conditions to supplement research on the influence of SBLM in the knowledge management field.

The authors collected 256 data points from employees across three stages using convenience sampling. The authors then tested the proposed hypothesis using hierarchical regression and bootstrap methods.

The results demonstrated that SBLM promotes employees’ moral disengagement, leading to more knowledge territorial behavior and knowledge sabotage behavior. Furthermore, high power distance orientation among employees exacerbates the ill effects of SBLM according to the first stage of a moderated mediation model. Employees with such an orientation are more likely to respond to a SBLM by exhibiting a higher level of moral disengagement, thus increasing their knowledge territorial behavior and knowledge sabotage behavior.

Research on the influence of SBLM in the knowledge management field is limited. This study not only clarifies the relationships between SBLM and two types of knowledge behavior (knowledge territorial behavior and knowledge sabotage behavior) but also enriches the research on the antecedents of these two types of knowledge behavior.

Existing literature has begun to identify the agonistic and contested aspects of the ongoing development of accountability systems. These “contests” are particularly important during periods of change when an accountability “deficit” has been identified, that is, when existing accountability systems are deemed inadequate and requiring revision. The purpose of this paper is to explore one such set of contests in the case of large technology and social media firms: the so-called “big tech”. The authors focus specifically on “big tech” because of increasing societal concerns about the harms associated with their products, services and business practices.

The authors analysed four US Congressional hearings, in which the CEO of Facebook was held to account for the company's alleged breaches and harms. The authors conducted a discourse analysis of the dialogue between the account giver (Mark Zuckerberg) and account holders (Members of Congress) in the oral testimony at the four hearings.

Two areas of contestation in the dialogue between the account giver and account holders are identified. “Epistemic contests” involved contestation about the “facts” concerning the harms the company had allegedly caused. “Responsibility contests” involved contestation about who (or what) should be held responsible for these harms and according to what standards or criteria.

The study advances critical dialogical accountability literature by identifying two areas of contestation during periods of change in accountability systems. In so doing, they advanced the theory by conceptualising the process of change as underpinned by discursive contests in which multiple actors construct and contest the “problem” with existing accountability systems. The outcomes of these contests are significant, the authors suggest, because they inform the development of reforms to the accountability system governing big tech firms and other industries undergoing similar periods of contestation and change.

This paper illuminates our journey as accounting educators by exploring accounting as a technical, social and moral practice towards decolonising ourselves. It lays the foundations for decolonising the higher education curriculum and the consequences for addressing the Sustainable Development Goals (SDGs).

This paper focuses on the potential to foster a space for praxis by adopting dialogism-in-action to understand our transformative learning through Jindaola [pronounced Jinda-o-la], a university-based Aboriginal knowledge program. A dialogic pedagogy provided the opportunity to create a meaningful space between us as academics, the Aboriginal Knowledge holder and mentor, the other groups in Jindaola and, ultimately, our accounting students. Since Jindaola privileged ‘our way’ as the pedagogical learning process, we adopt autoethnography to share and reflect on our experiences. Making creative artefacts formed the basis for building relationships, reciprocity and respect and represents our shared journey and collective account.

We reveal our journey of “holding to account” by analysing five aspects of our lives as critical accounting academics – the overarching conceptual framework, teaching, research, governance and our physical landscape. In doing so, we found that Aboriginal perspectives provide a radical positioning to the colonial legacies of accounting practice.

Our journey through Jindaola contemplates how connecting with Country and engaging with Aboriginal ways of knowing can assist educators in meaningfully addressing the SDGs. While not providing a panacea or prescription for what to do, we use ‘our way’ as a story of our commitment to transformative change.

This study aims to use a theoretical-based case study of two distinct ownership groups of the Jack Daniel’s brand to explore how rhetorical history (i.e. malleability of the past for strategic goals) may evoke and capitalize on different forms of nostalgia. Within, the authors configure four forms of nostalgia (i.e. personal, historical, collective and cultural) from the individual or collective interaction and level of direct experience one has with the past as lived or happened.

This study uses an historical research approach which involved the identification of primary and secondary sources, facility tour, source criticism and triangulation to create themes of rhetorical history infused with nostalgic narratives using compelling evidence through rich description of this fusion.

The findings reveal how nostalgia-driven narratives reflecting different collective longing for the re-creation of an American Paradise Lost used by Jack Daniel (i.e. the man) and later but differently by Brown-Forman. This study uncovers how the company’s inherited past was used rhetorically throughout its history, beginning with the nostalgic story of Jack Daniel and the distillery’s nostalgically choreographed location in Lynchburg, Tennessee. This study delves into this setting to highlight the importance of symbols, details, emotional appeals and communications for collective memory and identity development and to showcase the ways in which they are influenced by different types and forms of nostalgia.

This study adds to a limited number of studies focused on understanding the impact of founders on an organization’s brand and how that is malleable. This study responds to scholarly calls to study the influence of sequenced historical rhetoric on an organization and highlight the relevance of social emotions such as nostalgia for rhetorical history. Finally, the theoretical contribution involves the advancing and construction of a theory typology of nostalgia previously proposed by Havlena and Holak in 1996.

This paper aims to trace how Asian American girls engaged with civic learning in a virtual out-of-school literacy community featuring a curriculum of diverse literary texts.

The researcher used practitioner inquiry to construct a virtual literacy education community dedicated to the civic learning of Asian American girls.

The paper explores how participants mobilized critical practices of textual consumption and production rooted in their intersectional identities and embodied experiences to make meaning of the civic constraints and affordances of marginalized identities and to read and (re)design author choices for civic purposes. These findings – examples of youths’ critical civic meaning-making – indicate how they claimed space for Asian American civic girlhoods in literacy education.

This paper foregrounds how Asian American girls mobilize critical processes of text consumption and production to assert civic identities in literacy education – a significantly under-examined topic in literacy studies. This work has implications for how literacy practitioners and scholars can prioritize Asian American civic girlhoods through pedagogy and research.

PhD graduates are entering an increasing range of careers, but past research has highlighted a lack of preparation for these careers. This study aims to explore the reflections of PhD graduates from science and humanities and social science disciplines regarding support for career development (CD) during their study.

The authors used an explanatory sequential mixed-methods design and collected 136 survey responses and interviewed 21 PhD graduates from two US and one New Zealand universities to investigate their career readiness. Using the lens of Cognitive Information Processing theory, the authors explored the development of self-knowledge and career options-knowledge, and how support at the macro (institutional), meso (departmental) and micro (supervisors) levels influenced CD.

During doctoral study, there was very poor engagement with CD activities. Graduates displayed limited self-knowledge and poor knowledge about career options. Graduates reported drawing mainly on their departments and supervisors for career guidance. Although there were pockets of good practice, some departments were perceived as promoting academia as the only successful outcome, neglecting to support other possible pathways. Some graduates reported excellent supervisor support for CD, but others described disinterest or a damaging response if students said they were not wanting to pursue academia.

The enabling aspects for developing self- and options-knowledge are collated into a conceptual model, which identifies key factors at institutional, departmental and supervisor levels, as well as for PhD students themselves.

Meetings with colleagues are an essential activity in workplace collaboration. The iterative nature of collaborative work demands spaces that team members can access quickly and easily. Creating suitable meeting spaces will become more critical if the hybrid work model continues and the workplace environment becomes the hub for face-to-face collaborative time, learning and training. Workspace and fit-out is expensive so it is crucial that the investment in meeting spaces supports employees’ collaboration activities.

This paper presents a case study of a corporate organisation undertaken in New Zealand to investigate how employees from two business units use their workspace to collaborate within their own team and across other teams in their organisation. The study uses ethnographic techniques, including participant observation and in-depth face-to-face interviews.

The findings show that the frequency and nature of small group work in collaboration was underestimated in the initial planning of the new workspace. Although participants found the design and fit-out of the formal meeting rooms supportive of collaborative work, the meeting rooms were in high demand, and it was difficult to find a room at short notice. The breakout spaces were confusing because they lacked key design attributes identified by the participants as conducive to small group work. Design shortfalls together with fit-out features perceived as supportive of collaborative work are identified.

The research reports on employees’ perceptions and experiences across two functionally diverse business units, reflecting their different needs and concerns.

The literature on communication in change processes, although fundamental, appears to still be very fragmented. The purpose of this study is to provide an explanatory and integrated framework for the communication process in organizational change processes.

The authors conducted 22 semi-structured interviews with employees from 21 companies and 13 different sectors in Germany. The four-step Gioia inductive coding approach was adopted as the methodological approach of the current study.

A final research model reveals that the organizational change communication (OCC) process is marked by specific change-restraining forces associated with the fear of the unknown, habits and convenience. Results also suggest the importance of communication timing and factors that help shape the OCC process, namely the scope, contents and channels of the communication process. Finally, the current research highlights contextual variables of the OCC process, such as credibility or the level of honesty.

The importance of OCC, in particular the understanding of the scope, contents of the message and the channels of communication adopted in the change management process, are important variables in the complexity of change. The paper illustrates the intricacy of communication in change and reinforces the internal and external variables that help shape the OCC process, with implications for change agents and scholars.
