Abstract
Purpose
The US Government is challenged to maintain pace as the world’s de facto provider of space object cataloging data. Augmenting capabilities with nontraditional sensors present an expeditious and low-cost improvement. However, the large tradespace and unexplored system of systems performance requirements pose a challenge to successful capitalization. This paper aims to better define and assess the utility of augmentation via a multi-disiplinary study.
Design/methodology/approach
Hypothetical telescope architectures are modeled and simulated on two separate days, then evaluated against performance measures and constraints using multi-objective optimization in a heuristic algorithm. Decision analysis and Pareto optimality identifies a set of high-performing architectures while preserving decision-maker design flexibility.
Findings
Capacity, coverage and maximum time unobserved are recommended as key performance measures. A total of 187 out of 1017 architectures were identified as top performers. A total of 29% of the sensors considered are found in over 80% of the top architectures. Additional considerations further reduce the tradespace to 19 best choices which collect an average of 49–51 observations per space object with a 595–630 min average maximum time unobserved, providing redundant coverage of the Geosynchronous Orbit belt. This represents a three-fold increase in capacity and coverage and a 2 h (16%) decrease in the maximum time unobserved compared to the baseline government-only architecture as-modeled.
Originality/value
This study validates the utility of an augmented network concept using a physics-based model and modern analytical techniques. It objectively responds to policy mandating cataloging improvements without relying solely on expert-derived point solutions.

Abstract
Purpose
With the recent release of the National Standard for Mental Health and Well-Being for Post-Secondary Students, there is increased interest to integrate research and practice for mental health services on post-secondary campuses. Participant-oriented research is a useful framework to bridge this gap. This paper aims to describe the program development and evaluation process and reports challenges and lessons learned to inform future implementation strategies for similar endeavours.
Design/methodology/approach
A participant-oriented research approach was used to revise and evaluate an innovative interdisciplinary resilience program, entitled Roots of Resiliency, for post-secondary students.
Findings
This case analysis used the development and evaluation of Roots of Resiliency to demonstrate some of the strategies and challenges that exist for participant-oriented research related to mental health in the post-secondary context. Collaborative relationships among the various development team members contributed to an overall positive experience. Some challenges that others who work in post-secondary mental health field may consider include the need for content expertise, the ongoing need for communication among team members and the need for an effective system to give voice to all participants.
Originality/value
Any mental health program has a cultural component and is best co-developed by the particular students (e.g. indigenous students) who are to be served by the program. In this regard, the co-design and shared development and evaluation of the current mental health program is an example that can be emulated in other programs within the post-secondary context.

Abstract
Purpose
The presentation of in-vehicle warnings information at risky driving scenarios is aimed to improve the collision avoidance ability of drivers. Existing studies have found that driver’s collision avoidance performance is affected by both warning information and driver’s workload. However, whether moderation and mediation effects exist among warning information, driver’s cognition, behavior and risky avoidance performance is unclear.
Design/methodology/approach
This purpose of this study is to examine whether the warning information type modifies the relationship between the forward collision risk and collision avoidance behavior. A driving simulator experiment was conducted with waring and command information.
Findings
Results of 30 participants indicated that command information improves collision avoidance behavior more than notification warning under the forward collision risky driving scenario. The primary reason for this is that collision avoidance behavior can be negatively affected by the forward collision risk. At the same time, command information can weaken this negative effect. Moreover, improved collision avoidance behavior can be achieved through increasing drivers’ mental workload.
Practical implications
The proposed model provides a comprehensive understanding of the factors influencing collision avoidance behavior, thus contributing to improved in-vehicle information system design.
Originality/value
The significant moderation effects evoke the fact that information types and mental workloads are critical in improving drivers’ collision avoidance ability. Through further calibration with larger sample size, the proposed structural model can be used to predict the effect of in-vehicle warnings in different risky driving scenarios.

Abstract
Purpose
The purpose of this two-part research was to investigate the effect of remote learning on student progress in elementary education. Part 2, presented in this paper, is a follow-up study to examine how student progression in the two pandemic-induced environments compared to the pre-pandemic conditions.
Design/methodology/approach
The authors expanded the quantitative, quasi-experimental factorial design of the authors' initial study with additional ex-post-facto standardized test score data from before the pandemic to enhance the group comparison with a control: the conventional pre-pandemic classroom environment. Thus, the authors were able to examine in which ways the two pandemic-induced learning environments (remote and hybrid) may have affected learner progress in the two subject areas: English Language (ELA) and Math. Additionally, the authors provided a grade-by-grade breakdown of analysis results.
Findings
Findings revealed significant group differences in grade levels at or below 6th grade. In the majority of analyzed comparisons, learner achievement in the hybrid group was significantly lower than those in either the remote or the classroom group, or both.
Research limitations/implications
The additional findings further supported the authors' initial hypotheses: Differences in the consistency and continuity of educational approaches, as well as potential differences in learner predispositions and the availability of home support systems may have influenced observed results. Thus, this research also contributes to the general knowledge about learner needs in elementary education.
Originality/value
During the pandemic, remote learning became ubiquitous. However, in contrast to e-learning in postsecondary education, for which an abundance of research has been conducted, relatively little is known about the efficacy of such approaches in elementary education.

Abstract
Purpose
This study aims to understand better the student awareness and knowledge on how the Sustainable Development Goals (SDGs) are used in higher education institutions (HEIs) to motivate students’ learning on sustainability. It is essential to consider students’ understanding of sustainability at the end of their studies to assess whether they feel prepared to apply sustainability in their daily work life.
Design/methodology/approach
The study has a quantitative case study design, and the specific method used is an online survey with masters’ students using the university student platform EvaSys. The study assesses approaching how students perceive the overall education integrating sustainability into programs and curricula.
Findings
The results showed that work-integrated learning (WIL) projects learning and real-life experiences as part of their studies enhanced the students’ understanding of sustainability. Moreover, the study showed that integrating an understanding of the SDGs in teaching offers universities a way to frame students’ key competencies in ways that allow them to develop their interpersonal competencies as ambassadors for sustainability in their future work life.
Practical implications
This study supports the argument that WIL and real-life university experiences enhance students’ key competencies critical for sustainability.
Originality/value
The pedagogical approach advanced in this paper addresses how WIL and real-life experiences might develop students’ key competencies on sustainability. This approach indicates that working with SDGs in teaching encourages students to promote their interpersonal competencies for sustainability.
