Designing In Argentina With Indigenous Groups, Catalina Lucía Agudin
Designing In Argentina With Indigenous Groups, Catalina Lucía Agudin
DRS Biennial Conference Series
Indigeneity in Argentina has historically been oppressed. The project presented here is a collaboration between design researchers and students from Buenos Aires and Indigenous groups in Northern Argentina that combines anthropologi-cal and design methods. Participatory experiences are at the core of the pro-posal. Interactions within the communities led to various lines of work. The top-ics varied from textile production, natural coloring, traditional nourishment, and construction to didactic materials for schools within intercultural bilingual edu-cation. The results show not only material outcomes, but also how the project moved its participants. In light of the widely differing worldviews, the learning process became …

Empowering Urban Wellbeing And Biodiversity Through Design-Driven Citymaking, Laura Cipriani, Francesca Foglieni, Francesco Leoni, Stefano Maffei
DRS Biennial Conference Series
This paper presents a practice-based account of the roles that design can play in the realization of a biodiversity-driven approach to citymaking, specifically as part of urban regeneration. The authors first retrace the evolving relationship between design and citymaking in light of contemporary urban regeneration challenges, to identify the potential roles design can play in these contexts. Urban biodiversity is then explored as a factor relevant to urban well-being, ecosystem services, and proactive citizenship, clustering the types of actions that can support a biodiversity-sensitive urban regeneration. Following these premises, a portfolio of initiatives centered on urban biodiversity within a large-scale …

Rethinking 'Terms Of Service' Through Programmatic Time Travel, Seda Özçetin, Johan Redström
DRS Biennial Conference Series
The contexts of design are constantly changing, sometimes to the extent that once a ‘good’ designerly response to an issue, over time becomes increasingly problematic. Therefore, there is often a need to rethink design and its concepts. Programmatic design research may provide an exploratory space for inquiry through specific examples in relation to certain theoretical and conceptual framings. In this paper, we explore [dis/re]orientations towards design histories for creating alternative programmatic research spaces. We work through an everyday challenge, ‘Terms of Service’ (ToS), a regulatory mechanism amplifying power asymmetries in relating to data-intensive things. Disorienting design by making an odd …

Situated Partnerships To Face Food Waste Within A Neighborhood-Based Food Redistribution Service: The Case Of "Sospesa", Davide Fassi, Valentina Ferreri
DRS Biennial Conference Series
Neighborhoods can be seen as experimental hubs where innovative design strat-egies are tested within local communities, addressing the social and environ-mental issues that impact global cities and promoting more equitable futures. In current times of crisis, amid substantial food waste, urban areas are witnessing a growing phenomenon of vulnerable groups suffering from food poverty, often coupled with limited access to fresh food. This scenario has led to a proliferation of diverse charitable initiatives, concurrently fueling researchers' exploration of sustainable food commons and circular systems. However, to foster community-driven development of such models, it becomes imperative to structure services around local, …

Discovering Design Implications For Future Food Experiencing Artifacts, Yağmur Kocaman, Damla Gözde Kocaman, Oğuzhan Özcan
DRS Biennial Conference Series
Despite the growing number of research in Human-Food Interaction (HFI), studies mainly adopt a technology-oriented approach. The field focuses on creating foods computationally, leaving the device design neglected. This paper addresses this oversight by focusing on a prominent technology as a case study (i.e., 3D Food Printing) and exploring new forms and meanings HFI technologies may embody. We first explored domestic users' food-related dynamics, habits, and preferences in everyday life (N=19). We then present the outcomes of design workshops with 25 professional designers, resulting in 73 unique concepts aligned with the in-sights from domestic kitchen users. Overall, we extracted ten …

‘Does Phosphorus Want To Sound Like That?’: Experiencing More-Than-Human Futures, Anton Poikolainen Rosén, Camillo Sanchez, Felix Anand Epp
DRS Biennial Conference Series
The paper explores the learning possible from including the public in explora-tions of more-than-human future visions. We presented an installation at a de-sign festival of a speculative scenario that emerged from ethnographic research with urban permaculture farmers, using sounds to represent concentrations of nutrients in soil. We studied how visitors wearing a sensor ring experienced the playing of these sounds upon insertion of a finger in the installation’s soil. Re-sponses underscore the importance of cultivating the skill of noticing through deep listening, alongside the profound connection thus established between humans and the more-than-human world. In a further contribution to more-than-human …

Preventing Diabetic Foot Ulcers With Ehealth: Rethinking Digital Care In Co-Design, Deborah Pelders, Roy Van Den Heuvel, Mark Arts, Ittay Mannheim, Rens Brankaert
DRS Biennial Conference Series
The number of people with diabetes is projected to increase over the upcoming years, putting pressure on care systems. Many patients with diabetes are at high risk of developing foot ulcers. These patients often struggle to relate to and monitor the health of their feet in everyday life. While eHealth technologies show promise in supporting self-management of diabetes, their use is still limited in the context of diabetic feet. By following a design process using co-design practices, we developed a suitable eHealth application that supports people in preventing diabetic foot complications. Through a participatory design approach, we uncovered 11 design …
Becoming Microbes: An Approach To Cultivating Microbial Sensibilities In Biodesign, Jiho Kim, Raphael Kim, Joana Martins, Elvin Karana
Becoming Microbes: An Approach To Cultivating Microbial Sensibilities In Biodesign, Jiho Kim, Raphael Kim, Joana Martins, Elvin Karana
DRS Biennial Conference Series
Microbes assume an indispensable role in design, given their inherent adaptability, functional diversity, and abundance. Yet, designing with microbes presents notable challenges for biodesigners, stemming from, for example, the distinct temporalities and scales of microbes. Conversely, cultivating microbial sensibilities—reflecting human comprehension and alignment with the distinctive characteristics of microbes—stands out as a unique potential of biodesign for fostering a deep connection between humans and other living entities. In response, we present the concept of “becoming microbes”, a philosophically grounded approach advocating for a non-anthropocentric stance in biodesign, aiming at immersing biodesigners in the realms of microbes with a fresh perspective …

Despite the prevalence of depression in lactating mothers, there is a lack of knowledge about the excretion of antidepressants into breast milk and its potential adverse effects on infants. This creates concern, making depressed lactating mothers more likely to avoid pharmacological treatment. Clinical lactation studies are the most accurate and direct method to predict and demonstrate the excretion of antidepressants into human breast milk, and results from clinical studies can be included in drug labels to help physicians and patients make decisions on antidepressant use during lactation. However, there are limited clinical trials and studies on the pharmacokinetics of antidepressants …

Symbiotic Potential And N Returns In Forage And Grain Legumes For Improving The N Economy Of Tropical Cropping Systems, F D. Dakora, J A. Abdogoba
IGC Proceedings (1977-2023)
There were marked cultivar and species differences in the amounts of N fixed and potential N returns in five forage legumes and ten groundnut (Arachis hypogaea L.) cultivars evaluated for symbiotic performance in both Guinea and Sahel savanna environments. Of the forage legumes, the Crotalaria and Lablab species accumulated greater symbiotic N and therefore showed higher potential N returns for improving the N economy of soils in both Guinea and Sahel savanna in Africa. However, Lablab appeared to be better adapted to the drier Sahel environment compared to the other species. When nutrient imbalances in the Guinea savanna soil …

Integration Of Forage Legumes Into Maize/Elephant Grass Systems For Dairy Farming, E N. Sabiiti, J S. Mugerwa, P Ngategize, G Kyeyune
IGC Proceedings (1977-2023)
The livestock sector contributes about 30% of the total value of agricultural production but the sector does not meet the demand for milk. Currently, there is serious migration of the rural population to urban centres and this will lead to high demand for milk and milk products. Therefore, the development of peri-urban dairy production by the small scale farmers appears a promising option to solve the problems of malnutrition, increase household incomes and improve the quality of life of these farmers. The dominant production system practised is zero-grazing using improved dairy breeds and feeding elephant grass (Pennisetum purpureum) …

Exploring The Mechanistic Trail Connecting Cellular Function, Health, And Athletic Performance With Phase Angle: A Review On The Physiology Of Phase Angle And Exercise-Based Interventions, Trevor Short, Paulette Yamada
Topics in Exercise Science and Kinesiology
Topics in Exercise Science and Kinesiology Volume 5: Issue 1, Article 7, 2024. Bioelectrical impedance analysis-derived phase angle (PhA) has been widely used in clinical and sports settings, as it is positively associated with health and fitness. However, what PhA is measuring at the cellular level has not been addressed, which limits our interpretation of PhA. The purpose of this review is to provide a roadmap, starting with the mechanistic link between the dielectric properties of mammalian cells and their physiological function. In simplistic terms, PhA measures cellular permittivity and electrical conductivity. These characteristics determine cellular health and function. This …

Common Toadflax (Linaria Vulgaris) A Persistent Weed In Alfalfa (Medicargo Sativa) Hay Fields, J R. King, L Zaychuk
IGC Proceedings (1977-2023)
The spread and persistence of common toadflax (Linaria vulgaris) when growing alone and in competition with alfalfa (Medicargo sativa) maintained as a hay crop in central Alberta Canada was monitored over a four year period. Competition from alfalfa reduced the rate of spread of the weed, and multiple harvests of the crop prevented toadflax seed set. The presence of the weed did not significantly affect the yield of alfalfa.

IGC Proceedings (1977-2023)
Grass hay was baled with a variety of balers and tying materials in June, 1994 and 1995, at Jackson, Ohio. The bales were prepared and stored several ways. Waste hay accounted for less than ten percent of the dry matter after storage for six and eighteen months in all cases except one (a plastic wrap system intended for use with haylage). Bales stored inside had no waste. The best outdoor storage system, with less than one percent waste, used a ‘bale bonnet’ (top half covered with a plastic sheet) with the bale on a slatted pallet. One group of bales …

The effect of poultry litter (15% wet basis) additive on the quality of king grass (Pennisetum purpureum x P. americanum) silage was studied in a randomized block design experiment (8 replications). Compared with grass silage (G), grass + poultry litter (G+P) caused significant (P<0.05) reduction in moisture (G, 716 v G+P, 670 g/ kgDM), pH (5.41 v 4.72) and butyric acid (9.6 v 5.5 g/kgDM). Crude protein (CP, Nx6.25, g/kgDM), in vitro digestibility (IVOMD, g/ kgDM) and metabolizable energy (ME, MJ/kgDM) increased from (G)104, 536 and 8.00 to (G+P) 127, 613 and 9.19. In a feeding trial using St. Elizabeth x Barbados Blackbelly lambs G+P gave significantly (P<0.05) higher daily gain (182 v 149 for G). This was related to significantly (P<0.05) higher intake of CP and ME from G+P (71.9 v 55.1 g/d and 5.20 v 4.24 MJ/d).
