Abstract
Purpose
The purpose of this paper is to propose a novel curvilinear path estimation model employing multivariate adaptive regression splines (MARS) for mid vehicle collision avoidance. The two-phase path estimation scheme initially uses the offset (position) value of the front and the mid (host) vehicle to build the crisp model. The resulting crisp model is MARS regressed to deliver a closely aligned actual model in the second phase. This arrangement significantly narrows the gap between the estimated and the true path analyzed using the mean square error (MSE) for different offsets on Next Generation Simulation Interstate 80 (NGSIM I-80) data set. The presented model also covers parallel parking by encompassing the reverse motion of the host vehicle in the path estimation, thereby, making it amicable for real-road scenarios.
Design/methodology/approach
The two-phase path estimation scheme initially uses the offset (position) value of the front and the mid (host) vehicle to build the crisp model. The resulting crisp model is MARS regressed to deliver a closely aligned actual model in the second phase.
Findings
This arrangement significantly narrows the gap between the estimated and the true path studied using MSE for different offsets on real (Next Generation Simulation-NGSIM) data. The presented model also covers parallel parking by encompassing the reverse motion of the host vehicle in the path estimation. Thereby, making it amicable for real-road scenarios.
Originality/value
This paper builds a mathematical model that considers the offset and host (mid) vehicles for appropriate path fitting.

Abstract
Purpose
The purpose of this interdisciplinary study is to identify the aspects that faculty, student affairs educators and students indicate as salient for effective mentoring relationships that enhance ethical leadership development.
Design/methodology/approach
This exploratory qualitative inquiry used the Relational-Ethical-Affective-Dialogic (READ) mentoring model as a framework to examine the experiences of 13 undergraduate mentees and faculty/staff mentors in a formal mentoring program. Each study participant engaged in one semi-structured interview. Researchers coded and analyzed data using the sort and sift, think and shift process identifying power quotes to guide the thematic analysis.
Findings
The data collected in this study revealed insights into the aspects of mentor relationships that both undergraduate mentees and their mentors perceived as contributing to students' ethical leadership development. Salient elements included: (1) relational features of the mentee-mentor dynamic including trust and reciprocity; (2) structural features of the mentoring program including its focus on ethics; and (3) mentoring approaches that were attentive to power and positionality within the mentoring relationship and involved professional judgment about self-disclosure.
Originality/value
This study adds to the literature by exploring effective mentoring for ethical leadership development across disciplines. With colleges and universities serving a vital role in preparing the next generation of leaders for ethical engagement in their democratic and professional roles after graduation, it is imperative to broaden our understanding of how faculty and staff can support students' ethical leadership development.

Abstract
Purpose
Based on the research, the authors identify how four key concepts in disaster studies—agency, local scale, memory and vulnerability—are interrupted, and how these interruptions offer new perspectives for doing disaster research from and for the South.
Design/methodology/approach
Meta-analysis of case studies and revision of past and current collaborations of authors with communities across Chile.
Findings
The findings suggest that agency, local scale, memory and vulnerability, as fundamental concepts for disaster risk reduction (DRR) theory and practice, need to allow for ambivalences, ironies, granularization and further materializations. The authors identify these characteristics as the conditions that emerge when doing disaster research from within the disaster itself, perhaps the critical condition of what is usually known as the South.
Originality/value
The authors contribute to a reflexive assessment of fundamental concepts for critical disaster studies. The authors offer research-based and empirically rich redefinitions of these concepts. The authors also offer a novel understanding of the political and epistemological conditions of the “South” as both a geography and a project.

Abstract
Discussion of religion and education continues to evoke conceptions of confessional teaching; however, research and educational practices in recent decades illustrate an expanded understanding that relates to the teaching of, about, and from religion across formal and non-formal educational spaces in secular and religious spheres. An expanded understanding also illustrates various intersections between religion and education that extend beyond religious or non-sectarian instruction, to include everything from the recognition and accommodation of religious student identities in K-12 public school settings, to the internationalization of religious higher education. Drawing on the Comparative and International Education Society’s Religion & Education Special Interest Group’s programing and activities, this paper aims to present a brief summary of trends observed both in research and practice concerning religion and education among educators worldwide, and highlights the place of religion in our growing recognition of intersectionality, one that occurs between academics and the community.

Abstract
Purpose
The purpose of this paper is to make visible the ways in which peoples’ experiences of mental ill health are coordinated and produced in the workplace setting.
Design/methodology/approach
This institutional ethnography draws from data collected from 16 informants in one Canadian industrial manufacturing plant to explicate how texts organize activities and align worker consciousness and actions with company expectations of a “bona fide” illness.
Findings
The findings demonstrate how a “bona fide” illness is textually mediated by biomedical and physical work restrictions, thus creating a significant disjuncture between an experiential and ruling perspective of mental ill health.
Research limitations/implications
The work of employees living with self-reported depression becomes organized locally and translocally around the discourse of “mental illness is an illness like any other.” This presents a profound disjuncture between the embodied experience of being too unwell to mentally perform work duties, and the textually coordinated practices of what it means to access sick time for a “bona fide illness” within a biomedical-based attendance management protocol.
Originality/value
The current study adds to the literature by shedding light on the disjuncture created between the embodied experience of mental health issues and the ruling perspective of what constitutes a bona fide illness, adding a unique focus on how people’s use of attendance management-related supports in the workplace.

Abstract
Purpose
Sport management research that examines children as a distinct group of sport consumers is sparse, and therefore the authors know relatively little about how and why children become fans of sport teams. The purpose of this paper is to explore the game-day experiences of children in order to better understand how these experiences allow children to socialize into the team community and become fans of the team.
Design/methodology/approach
The authors examine this through exploratory observational analysis and 26 semi-structured interviews with children at professional sporting events.
Findings
Among the results, it was found that children primarily focus on exploring ways to build membership in the fan community as opposed to initially building connections to the team itself. In addition, those children that watched the games with their peers demonstrated greater in-game emotional responses than those children that viewed the game with family.
Research limitations/implications
This study provides support for the importance of community membership in the initial stages of sport team fandom as well as the varying effects of different groups within fan communities on child fans. However, further research is needed to increase the generalizability of the results.
Practical implications
It is recommended that sport teams increasingly target groups that will bring children to games with their peers in order to enhance their game experience and increase their socialization into fandom.
Originality/value
This paper is one of the first in sport management to directly look to better understand children and the ways in which they become fans of sports teams.

Abstract
There is substantial anecdotal evidence that, whilst popular in current international consumer markets, the grape variety sauvignon blanc is viewed ambivalently by some wine industry professionals. This study examines evidence for that anecdotal perspective. It reports first the findings from a qualitative research project that provided some support for the proposition that wine industry attitudes to the grape variety are ambivalent. Further qualitative research, involving semi‐structured interviews, was then carried out to examine precisely why that ambivalence exists, and to explore in depth the perspectives of Australian wine industry professionals towards sauvignon blanc. The findings suggested both physiological and social reasons for this dislike. The study has relevance in two areas. The first is in the development of a theoretical understanding of how those who are responsible for the production of aesthetic products may approach working with material that they may dislike, or have little regard for. The second is more practical, and informs how those marketing sauvignon blanc should view the product.
