Paper Session I-C - Commercial Infrastructure Participation in the Space Station Freedom Program
The evolution phases of Space Station Freedom offer the private sector the opportunity to provide commercial infrastructure to NASA and other users of the Space Station. This paper discusses the opportunities for infrastructure beyond the baseline Space Station and describes several approaches to initiating the provision of commercial infrastructure. These approaches include unsolicited proposals from the private sector, commercial development of infrastructure, and commercial operation of infrastructure
Delivering Urban Wellbeing through Transformative Community Enterprise: Final Report
Urban communities around the world are using farming and gardening to promote food security, social inclusion and wellbeing (Turner, Henryks and Pearson, 2011). In the New Zealand city of Christchurch, a recently formed social enterprise known as Cultivate currently operates two such urban farms. The farms, which use vacant urban land and green waste to grow and distribute locally grown food, are based around an innovative community form of economy that provides care and training for urban youth. The farms provide a therapeutic environment that is co-created by youth interns, urban farmers, social workers and community volunteers. Cultivate’s urban farms are a valuable example of a creative urban wellbeing initiative that may be useful for other organisations seeking to promote youth wellbeing, hauora,1 social development and urban food security in Aotearoa New Zealand and further afield. To document and measure the holistic impact of Cultivate, we collaborated with Cultivate staff, youth interns and other stakeholders to extend an already existing assessment tool: the Community Economy Return on Investment (CEROI). The CEROI tool was workshopped with urban designers, planners, and community practitioners to test its potential for documenting the non-monetary return of Cultivate’s work, and then communicating this return to those involved in other urban wellbeing projects. This report summarises the research and explains how we used the CEROI tool to document and measure the transformative social and environmental outcomes of Cultivate’s activities. Cultivate is the site in which effort, relationships, money and materials are brought together. It is a site which produces a significant amount of food, but its benefits also extend to changed lives, changed relationships, and a more positive sense of Christchurch as a post-disaster city. These returns on Cultivate’s activities are not captured by notions of profit, ‘savings from helping young people to avoid the justice system’, or even the production of ‘good workers for the economy’. Instead, they might be described as ‘something more’. This research responds to the need to develop a language and an approach to thinking about value that helps us to represent this ‘something more’. We show how the concept of return on investment from a community economies perspective can enable us to describe and document this return in a more holistic sense (especially in comparison to conventional financial accounting approaches). We also suggest that the Cultivate case study offers an important example of how mental wellbeing and access to therapeutic urban environments can be addressed through the work of a self-sustaining community enterprise. In offering this perspective, we acknowledge that further work is required to refine the CEROI tool, so that it can be used to support the work of other community and social enterprises
Kant’s Causal Power Argument Against Empirical Affection
A well-known trilemma faces the interpretation of Kant’s theory of affection, namely whether the objects that affect us are empirical, noumenal, or both. I argue that according to Kant, the things that affect us and cause representations in us are not empirical objects. I articulate what I call the Causal Power Argument, according to which empirical objects cannot affect us because they do not have the right kind of power to cause representations. All the causal powers that empirical objects have are moving powers, and such powers can only have spatial effects. According to Kant, however, the representations that arise in us as a result of the affection of our sensibility are non-spatial. I show that this argument is put forward by Kant in a number of passages, and figures as a decisive reason for rejecting empirical affection and instead endorsing affection by the things in themselves
Design simplicity influences patient portal use: the role of aesthetic evaluations for technology acceptance
Objective This study focused on patient portal use and investigated whether aesthetic evaluations of patient portals function are antecedent variables to variables in the Technology Acceptance Model
Temperature acclimatisation of swimming performance in the European Queen Scallop
The phenotypic plasticity of muscle performance and locomotory physiology allows the maintenance of essential activity capacity in the face of environmental change, and has been demonstrated in a wide phylogenetic range of eurythermal vertebrates. This study used the scallop, Aequipecten opercularis, as a model eurythermal invertebrate. Animals caught in different seasons demonstrated marked differences in their swimming performance and the relationship between, temperature and performance. When stimulated to swim at natural ranges of temperature, Winter (cold acclimatised), animals accelerated faster than autumn collected animals swimming at the same temperature (x 2 at 11degreesC) and attained higher velocities during jetting. The effects of acclimatisation were confined to the jetting phase and may be a mechanism for the maintenance of acceleration during predator-prey interactions. This is the first demonstration of the thermal acclimatisation of muscle performance in a mollusc and one of very few studies in invertebrates

Assessing air quality and physical risks to E-scooter riders in urban environments through artificial intelligence and a mixed methods approach
The need to develop green and smart transport solutions for NetZero cities to reduce carbon emissions through the use of clean energy is driving innovation in cities around the world. A result of this trend is a rise in micro-mobility solutions such as e-scooters in cities around the globe. Nottingham (UK) is one of the cities that conducted an e-scooter pilot scheme permitting the rental of e-scooters to travel around the city in a bid to encourage more sustainable personal transport use. However, to ensure pedestrian safety, e-scooters are required to be ridden on the road network among cars. Hence, giving rise to two potential risks for e-scooter users: the air quality that they breathe and the physical risk of being near cars, whose drivers may be unfamiliar with seeing e-scooters on the road.
This study seeks to explore this interaction using a mixed methods approach to explore the experiences of e-scooter riders in respect to their physical safety and exposure to air pollution. The research makes use of two quantitative surveys an international e-scooter user survey n = 801 and a survey of UK car drivers n = 92, focussed qualitative e-scooter rider interviews and quantitative in-depth road data collection trials comprising of air quality particulate sensing, video capturing around the rider and GPS tracking. The in-depth road data was analysed using an AI approach utilising the ASPS approach, the automated sensor and signal processing approach, implemented for image and signal processing to detect the existence of cars alongside the pollution readings.
The findings show that e-scooter riders are typically aware of physical dangers to their safety from other road users, as well as how their presence among pedestrians can impact on more vulnerable users; however, they were unaware of the prevalence and effects of air pollution on them whilst riding. The study highlights the need for a multifaceted approach to improvements in safety for micro-mobility users, predominately considering suitable infrastructure to sperate them from motor vehicles and pedestrians but also the need to consider the proximity to emission emitting vehicles, developing infrastructure in green spaces to address these air pollution levels

Towards more sustainable urban transportation for NetZero cities: assessing air quality and risk for e-scooter users using sensor fusion and artificial intelligence
The need to develop smart and NetZero cities and reduce carbon emission is driving innovation in cities around the world to use electric transportation technologies. Among that the use of e-scooters. Nottingham (UK) is one of the cities that has an e-scooter scheme where people could rent e-scooters to travel around the city. However, in the current situation, to ensure pedestrian safety e-scooters need to be ridden on the road amongst cars, most of them are fossil fuelled. This gives rise to two potential risks for e-scooter users: the air quality that they breathe and the physical risk of being near cars, where drivers may not be familiar with seeing e-scooters on the road. This paper uses a mixed methods approach by conducting surveys to drivers and e-scooter users, jointly with an experimental work to monitor the journey of e-scooter users combining air quality, GPS data and 360 degrees camera footage to assess the risk to e-scooter riders using sensor fusion and artificial intelligence. The results indicate that the suggested novel methodology is effective in understanding the current limitations and the potential air quality and physical risks to e-scooter users
Social work education in the shadow of confederate statues and the specter of white supremacy
Driven by our code of ethics and our call to reckon with our embeddedness within a white supremacist institution in the US South, the UNC-Chapel Hill School of Social Work re-visioned our approach to the MSW curriculum. Using case study methods, we trace our history and on-going work through interviews, document review, and community conversations, centering student voices. Students interviewed spoke about activism prompted by racist events on campus and nationally, and the inadequate response from the administration. Their efforts led to school-wide initiatives including curriculum shifts and accountability and action. The first-year generalist course, Confronting Oppression and Institutional Discrimination was restructured and resituated. Critical Race Theory was infused across the coursework. Two new working groups were created: The Anti-Racism Task Force and Reconciliation Standing Committee. Efforts to address racism and white supremacy in academic spaces require sustained activism to expose how racism is embedded within our institutions. While much work remains in the practice of becoming an antiracist institution, this model can serve as a prototype for others as they work to create programs that are site-specific and universally reflective of the institutional changes we need
Density data for Lake Ontario benthic invertebrate assemblages from 1964 to 2018
Benthic invertebrates are important trophic links in aquatic food webs and serve as useful bioindicators of environmental conditions because their responses integrate the effects of both water and sediment qualities. However, long-term data sets for benthic invertebrate assemblages across broad geographic areas are rare and, even if collected, historic data sets are often not readily accessible. This data set provides densities of benthic macroinvertebrates for all taxa collected during lake-wide surveys in Lake Ontario, a Laurentian Great Lake, from 1964 to 2018. This information resulted from surveys funded by the governments of the United States and Canada to investigate the status and changes of Lake Ontario benthic community. Of the 13 lake-wide benthic surveys conducted in Lake Ontario over the course of 54 yr, we were able to acquire taxonomic data to the species level for 11 of the surveys and data to the group level for the other two surveys. Density data are provided for taxa representing the Annelida, Arthropoda, Mollusca, Cnidaria, Nemertea, and Platyhelminthes phyla. Univariate and multivariate analyses revealed that the compositional structure of Lake Ontario invertebrate assemblages differed markedly by depth and were also significantly altered by the Dreissena spp. invasion in early 1990s. The introduction of invasive dreissenids has changed the community historically dominated by Diporeia, Oligochaeta, and Sphaeriidae, to a community dominated by quagga mussels and Oligochaeta. Considering the rarity of long-term benthic data of high taxonomic resolution in lake ecosystems, this data set could be useful to explore broader aspects of ecological theory, including effects of different environmental factors and invasive species on community organization, functional and phylogenetic diversity, and spatial scale of variation in community structure. The data set could also be useful for studies on individual species including abundance and distribution, species co-occurrence, and how the patterns of dominance and rarity change over space and time. Use of this data set for academic or educational purposes is encouraged as long as the data source is properly cited using the title of this Data Paper, the names of the authors, the year of publication, the journal name, and the article number
