The proliferation of lean principles in the construction industry is offset by the enduring uncertainty among industry stakeholders regarding their respective roles in lean implementation. This uncertainty is further compounded by the scarcity of empirical investigations in this area. Consequently, this study undertakes the task of bridging this knowledge gap by identifying the critical roles of lean learners and their indispensable contributions to achieving successful lean implementation.

A qualitative exploratory approach informed by an interpretivism perspective was adopted. The case study strategy was employed to gather data from three contracting organisations that had implemented lean practices. Empirical data was collected through in-depth semi-structured interviews with fifteen industry experts and complemented by document reviews. To analyse the data, a code-based content analysis approach was employed using NVivo software, while Power BI software was utilised to develop a comprehensive force-directed graph visualisation.

The research findings substantiated nine lean learners and unveiled a set of seventy-three roles associated with them. The force-directed graph facilitated the identification of lean learners and their connections to the emerged roles. Notably, the graph highlighted the pivotal role played by project managers and internal lean trainers in ensuring the success of lean implementation, surpassing the contributions of other lean learners.

The implications of findings extend to industry professionals seeking to establish a robust lean learning framework to expedite lean implementation within the construction sector. This study not only provides a comprehensive definition of lean learners’ roles but also transcends specific construction types, making it a significant catalyst for global impact.

This study aims to examine whether country of residence, sex trafficking attitudes, complainant gender, juror gender and right-wing authoritarianism (RWA) influenced juror decision-making within a sex trafficking case.

Jury-eligible participants from the USA and the UK participated in an online juror experiment in which an independent group design was used to manipulate the complainant’s gender. Participants completed the juror decision scale, the sex trafficking attitudes scale and the RWA scale.

Sex trafficking attitudes predicted the believability of both the defendant and complainant. Greater negative beliefs about victims predicted greater defendant believability and lower complainant believability. US jurors reported greater believability of both the complainant and defendant, and RWA was associated with greater defendant believability. However, none of the other factors, including complainant and juror gender, predicted participants’ verdicts. The findings suggest juror verdicts in sex trafficking cases may be less influenced by extra-legal factors, although further research is needed, especially with a more ambiguous case.

This is one of the few cross-cultural comparison studies in the area of jury decision-making, specifically regarding sex trafficking cases. The findings indicated that US participants held more problematic attitudes about sex trafficking than their UK counterparts, although all participants held problematic attitudes about sex trafficking. However, those attitudes did not affect verdict formation about either a male or female complainant. Participants who were more knowledgeable about sex trafficking reported greater complainant believability, suggesting that educational interventions may provide greater support for victims in court.

As part of a larger grant-funded project, a professional development (PD) series was conducted within the framework of a school–university partnership to improve teachers’ capacity to meaningfully include fathers and father figures in the school environment, with a particular focus on fathers of children with disabilities. The authors sought to understand the extent to which a school-wide PD framed through the lens of a father of a child with a disability might inform practice with sustainable implementation. Due to the pandemic, the original format of the PD was redesigned for virtual delivery.

A three-phase data collection and analysis approach included a pre-PD survey, a post-PD survey and a one-year follow-up survey. All surveys included both quantitative and qualitative self-report data components.

Results suggest school personnel found the virtual PD valuable, gleaning several useful strategies for reflecting on their own practices, working to improve communication with families of children with disabilities and more meaningfully including fathers and father figures in future school-related activities and programing.

First, the sample size of the present study was small, and participation was variable across PD sessions. In addition, participants self-selected into the series, and therefore, they may be more likely to value father-figure involvement with or without participation in the PD series. The small sample size may minimize the generalizability of these results across other replicable settings and participants. Second, the results of the pre-PD survey could be positively skewed since the university partner’s initial delivery of PD related to this topic began in 2018. In the pre-PD survey, the majority of respondents indicated, as an example, that they believed father involvement was correlated with higher academic achievement. It is not clear if respondents held these beliefs independently at the inception of the partnership or if they perhaps learned of these connections during an earlier PD offered by the authors.

The current study offers a small glimpse into the world of a school–university partnership and its ability to actualize meaningful reflection on family engagement practices. Results also indicate a greater awareness of significant male figures/fathers and their needs. Content delivered during each PD supports capacity building in terms of teachers’ ability to see fathers and father figures as meaningful contributors within the context of the school environment. Participants mentioned that the PD taught them ways to recognize and remediate some of the insidious communication barriers that exist.

Participants stated that they grew in their understanding of intentional connections with significant male figures, noting a concerted effort to ensure communication of information pertaining to school events, conferences and, in some cases, individualized educational programs (IEPs). Staff members also felt as though the pandemic fostered greater connections with fathers who were working at home and who were simultaneously helping their children access online learning platforms. However, it is noteworthy that the latter benefit was likely a positive side effect of mandatory home-based learning as opposed to a direct result of the present study. Socially, the authors all find ourselves embarking on a bit of social uncertainty, where perhaps it is no longer appropriate or significant to mention one's gender. Nonetheless, the research highlights the unique contributions that fathers and father figures can make to children's positive trajectory, and the authors espouse that the current study suggests that virtual PD sessions can help train school personnel to recognize and foster such relationships.

The past few decades have ushered in an awareness of significant male involvement and its importance in the development of young children. Despite this surge of interest, the research on father/significant male involvement in the school context remains limited. Additionally, the implementation of virtual PD and its potential positive impacts remain largely unexplored, especially when the intersection with father engagement practices is considered. As such, the authors espouse that the present study reflects a unique combination of content and pedagogy.
