Fostering improved learning about sustainability

University business graduates must not only understand but also be equipped to apply a sustainable thought process to today's business challenges. However, evidence suggests that standard approaches to teaching business courses have not advanced to reflect changing student needs, especially for NetGen students who have differing expectations than earlier cohorts. The current challenge for instructors concerns the preservation of rigor and integrity in course design, while responding to the needs of a new generation of learners. This article presents a conceptual framework incorporating experiential learning, reflective practice, and the use of metaphor, with application to the teaching of sustainability within a number of business courses

Thermal infrared spectroscopy of Europa and Callisto

The trailing hemispheres of Europa and Callisto were observed at 9–13 μm, and a spectrum of Europa with better spectral resolution and a better signal-to-noise ratio than was previously possible has been derived. The ratio spectrum of the two satellites has a signal-to-noise ratio of approximately 30 for a spectral resolving power of approximately 50. The disk-integrated, effective color temperature ratio for the two satellites is consistent with broadband, thermal infrared photometry from previous ground-based studies and from the Galileo photopolarimeter radiometer. The ratio spectrum was combined with the average Voyager 1 spectrum of Callisto to obtain a 9–13 μm spectrum of Europa with a signal-to-noise ratio that is a factor of 10 better than that in the average Voyager spectrum of Europa. After convolving the measured spectrum to the expected width of water ice emissivity features, ∼1 μm, no spectral features that could be attributed to water ice on the surface of Europa are apparent at the 0.6–0.7% level. The absence of spectral features attributable to water ice is consistent with the proposal that the equatorial region of Europa that was observed may be composed primarily of a heavily hydrated mineral. The absence of water ice features may also be the result of a large fractional abundance of fine particles, such as that found on the surface of the Moon

The impact of solar cell technology on planar solar array performance

The results of a study into the potential impact of advanced solar cell technologies on the characteristics (weight, cost, area) of typical planar solar arrays designed for low, medium and geosynchronous altitude earth orbits are discussed. The study considered planar solar array substrate designs of lightweight, rigid-panel graphite epoxy and ultra-lightweight Kapton. The study proposed to answer the following questions: Do improved cell characteristics translate into array-level weight, size and cost improvements; What is the relative importance of cell efficiency, weight and cost with respect to array-level performance; How does mission orbital environment affect array-level performance. Comparisons were made at the array level including all mechanisms, hinges, booms, and harnesses. Array designs were sized to provide 5kW of array power (not spacecraft bus power, which is system dependent but can be scaled from given values). The study used important grass roots issues such as use of the GaAs radiation damage coefficients as determined by Anspaugh. Detailed costing was prepared, including cell and cover costs, and manufacturing attrition rates for the various cell types

Missed That! Roadway Drainage Lessons Learned

Intersection improvements and downtown beautification projects are common essential improvements that benefit motorists and residents of urban communities. When scoping, it is easy to disregard drainage in order to minimize cost and reduce staffing needs. However, sometimes big problems can happen when roadway drainage is not assessed. Come take a deep dive into a few examples of drainage oversights and how they were remedied

Proactively Upgrading Aging Infrastructure for Multi-modal Corridor Renewal

Indiana is experiencing urban renewal. Urban multi- modal corridor renewal in an aging, socioeconomically challenged area has its challenges on the surface; however, what is underground can be equally challenging. In Florida, Burgess & Niple partnered with FDOT and the City of Tampa to proactively resolve the flooding on 8 miles of one-way pairs. Twelve existing 100-year-old drainage systems discharging to the Hillsborough River were modeled and upgraded, setting the foundation for the surface Complete Streets improvements

Molecular Simulations of Alternate Frame Folding in Engineered Protein-Based Switches

Living organisms take advantage of proteins in order to carry out most of the biological tasks that keep them alive. Although most proteins do not drastically change shape, some behave as conformational switches: in response to an outside signal from its environment, the protein will shape-change to either an “on” or “off” position. These properties of conformational switches have motivated recent efforts towards the conversion of regular ligand binding proteins into novel switches for use as optical sensors and therapeutics. Here we seek to examine one such design that exhibits an intermolecular tug-of-war between two alternate frames of folding that can be made sensitive to calcium. The challenges of elucidating structural and mechanistic details from a partially unfolded protein have led us to consider coarse-grained simulation techniques. We plan to demonstrate that results from these simulations are in agreement with experimental data and can provide novel insight into the mechanisms of switching in this class of engineered proteins

Does Hydrotherapy Impact Behaviours Related to Mental Health and Well-Being for Children with Autism Spectrum Disorder? A Randomised Crossover-Controlled Pilot Trial

Background: Children diagnosed with Autism Spectrum Disorder (ASD) are less physically active than typically developing children due to reduced socialisation and delayed gross-motor skills, negatively impacting social, emotional and physical well-being. This study aimed to determine whether hydrotherapy influences behaviours which impact mental health and well-being in children with ASD. Methods: A within-subjects, randomised crossover-controlled pilot trial was used over 8 weeks. Children aged 6–12 years and diagnosed with ASD (n = 8) were randomly allocated to Group 1 (n = 4) or Group 2 (n = 4). All children participated in hydrotherapy intervention from either weeks 1 to 4 or weeks 5 to 8. The Child Behaviour Checklist (CBCL) measured behaviour changes impacting mental health and well-being, administered at weeks 0, 4 and 8. Results: No observable differences were found in CBCL subscales between Group 1 or 2 at baseline (week 0). Paired-samples t-tests revealed significant improvements post-intervention: Anxious/Depressed subdomain (p = 0.02) and the Internalising Problems Domain Summary (p = 0.026), with large effect size (d = 1.03 and d = 1.06 respectively). Thought Problems (p = 0.03) and Attention Problems (p = 0.01) both significantly improved post-intervention. The Total Problems score significantly improved post-intervention (p = 0.018) with a large effect size (d = 1.04). Conclusion: Hydrotherapy may enhance behaviours impacting mental health and well-being of children with ASD and could be considered a beneficial therapy option
