Design Thinking in Higher Education: Opportunities and Challenges for Decolonized Learning

This article builds upon current research to understand the value and limitations of teaching and learning design thinking (DT) in higher education. We implemented a mixed-methods study with faculty and students across 23 diverse courses in four higher education institutions in the United States. Findings showed that following structured learning processes, engaging in active listening, and focusing on others’ perspectives were the most valued DT practices across disciplines. In contrast, prototyping and experimentation were the least used DT practices, with widely varying understandings across disciplines. Additionally, we found consistent evidence that DT can support liberatory teaching and learning practices that decolonize students’ perceptions of power, encourage situated and action-oriented empathy, and provide opportunities for co-creation. This is particularly true when faculty intentionally encourage collaboration and project framing focused on critically analyzing dominant ways of knowing and power structures. Our analysis further revealed the challenges and importance of prototyping and conducting experiments with project partners. Ultimately, this approach can significantly enhance liberatory project outcomes and facilitate decolonized learning experiences. Given our findings, we point out limitations and challenges across current DT pedagogical practices and provide recommendations for integrating DT practices across disciplines in ways that center on issues of systemic oppression, social identity, and human-environmental relationships

Mushrooms may be good medicine

in “Medical and dietetic students often co-author a column for the Daily Reflector under Dr. Kolasa's byline. The students research the topic a reader or patient has asked. Dr. Kolasa reviews their draft for technical accuracy, patient friendly language, people first language. She fact checks the study or other evidence-based reference the student provides. If a physician review is appropriate, Dr. Kolasa requests a colleague from ECU physicians to review the article. The final draft is submitted to the Reflector with the editor having the final say. The headline is written by the Reflector headline writer. The food and nutrition column has run weekly since 1987. Starting in 2020, in addition to the Daily Reflector, the article is published in daily and weekly papers owned by the Adams Publishing Group East (https://adamspg.com)�This is a weekly Q and A newspaper column under the byline of Dr. Kathy Kolasa. Today's column is about medicinal mushrooms and some if the potential benefits and risks, especially related to cancer and neurogenerative disease.

Sorption behaviour of per- and polyfluoroalkyl substances (PFASs) in tropical soils

The sorption behaviour of three perfluoroalkyl substances (PFASs), namely perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid (PFOA) and perfluorohexane sulfonic acid (PFHxS), was determined on 28 tropical soils. Tropical soils are often highly weathered, richer in sesquioxides than temperate soils and may contain variable charge minerals. There are little data on sorption of PFASs in tropical soils. The highest Kd values were found for PFOS with mean values ranging from 0 to 31.6 L/kg. The Kd values for PFOA and PFHxS ranged from 0 to 4.9 L/kg and from 0 to 5.6 L/kg, respectively. While these values are in the range of literature sorption data, the average Kd values for PFOS and PFOA from the literature were 3.7 times and 3.6 times higher, respectively, than those measured in this study. Stepwise regression analysis did explain some of the variance, but with different explanatory variables for the different PFASs. The main soil properties explaining sorption for PFOS and PFOA were oxalate-extractable Al and pH, and for PFHxS was pH

Faculty experiences and motivations in design thinking teaching and learning

IntroductionDesign thinking (DT) is a creative, iterative approach to generating solutions that are desirable, feasible, and viable. Given its role in fostering creativity and innovation, a growing number of higher education instructors are teaching DT. Exploring how and what instructors know about DT and why they might teach it could provide critical insight into the ways in which DT is operationalized in higher education teaching and learning.Materials and methodsA convergent parallel mixed methods design was used for data collected from online surveys administered to faculty teaching DT. The survey included items about DT practices, outcomes from DT, demographic characteristics, and course characteristics. Five open-text survey items queried participants about their definition of DT, why they teach DT, and what additional outcomes they observed. Descriptive statistics were used to analyze quantitative items and thematic analysis was used to analyze qualitative items.ResultsParticipants (n = 49) represented various academic ranks, disciplines, types of institutions, and geographic locations. Analyses indicated clear congruence between quantitative and qualitative data. Definitions of DT aligned with well-known models of DT. Motivations for teaching DT included the promotion of personal development, DT proficiency, impact, and interpersonal skill development. Other positive student outcomes observed included increases in enthusiasm, self-awareness, empowerment, optimism, and a sense of belonging. Negative student outcomes included time constraints, teamwork conflicts, and student frustration.ConclusionFaculty believe that DT leads to highly valuable social innovation skill sets for students. This cross-institutional, multi-disciplinary study provides critical insight into faculty experiences and motivations for teaching DT, offering various strategies for instructors and institutions interested in fostering the uptake of DT within higher education

The role of surface charge and pH changes in tropical soils on sorption behaviour of per- and polyfluoroalkyl substances (PFASs)

The net surface charge became less negative with decreasing pH (from 7.5 to 3.5) in all soils. The rate of change in net surface charge varied from −0.6 to −2.8 (cmol/kg)/pH unit. The effect on sorption behaviour of PFASs was variable among soils. For two soils, the average sorption increased 54- and 45-fold for PFOS, 33- and 9-fold for PFOA, and 39- and 400-fold for PFHxS, across the pH range 7.5 to 3.5. Sorption in another sandier soil showed negligible change with decreasing pH. Sorption in the other soils did not change significantly until the pH decreased to approximately 5.5. The soils with high contents of sesquioxides (Fe and Al oxides) showed the most marked increase in sorption with decreasing pH. This study demonstrated that in addition to hydrophobic interactions with OC and other processes, electrostatic interactions are also important in the sorption process for these chemicals in soils. In acidic, variably charged tropical soils there is the possibility that any PFOS, PFOA or PFHxS sorbed to the soils may become desorbed if management practices (e.g. liming) raised soil pH

EatWellNow: Formative Development of a Place-Based Behavioral “Nudge” Technology Intervention to Promote Healthier Food Purchases among Army Soldiers

Approximately 17% of military service members are obese. Research involving army soldiers suggests a lack of awareness of healthy foods on post. Innovative approaches are needed to change interactions with the military food environment. Two complementary technological methods to raise awareness are geofencing (deliver banner ads with website links) and Bluetooth beacons (real-time geotargeted messages to mobile phones that enter a designated space). There is little published literature regarding the feasibility of this approach to promote healthy behaviors in retail food environments. Thus, we conducted a formative feasibility study of a military post to understand the development, interest in, and implementation of EatWellNow, a multi-layered interactive food environment approach using contextual messaging to improve food purchasing decisions within the military food environment. We measured success based on outcomes of a formative evaluation, including process, resources, management, and scientific assessment. We also report data on interest in the approach from a Fort Bragg community health assessment survey (n = 3281). Most respondents agreed that they were interested in receiving push notifications on their phone about healthy options on post (64.5%) and that receiving these messages would help them eat healthier (68.3%). EatWellNow was successfully developed through cross-sector collaboration and was well received in this military environment, suggesting feasibility in this setting. Future work should examine the impact of EatWellNow on military service food purchases and dietary behaviors

Nucleic acid cytokine responses in obese children and infants of obese mothers

Almost a third of Irish children are now overweight and the country ranks 58th out of 200 countries for its proportion of overweight youths. With the rising obesity epidemic, and the impaired immune responses of this population, it is vital to understand the effects that obesity has on the immune system and to design future therapeutics, adjuvants and vaccines with overweight and obese populations in mind. Many current vaccines use adjuvants that have been found to be less effective at stimulating the immune response in children compared with adults and there is now substantial effort to design paediatric-focused adjuvants. Additionally, vaccine responses have been shown to be less effective in obese populations indicating that this is a particularly vulnerable population. We have recently identified cytosolic nucleic acids (CNAs), as novel candidate adjuvants for childhood vaccines. Here we investigated whether immune responses to these candidate adjuvants were adversely affected in infants born to overweight or obese mothers, and in overweight and obese children. Type I Interferon (IFN) and proinflammatory cytokines such as Tumor Necrosis Factor α (TNFα) are vital for driving innate and adaptive immune responses. We found that childhood obesity conferred no significant adverse effect on CNA-induced Type I IFN responses when compared with lean children. Similarly, Type I IFN responses were intact in the cord blood of babies delivered from overweight and obese mothers, when compared with lean mothers. There was also no significant impact of obesity on CNA-induced TNFα responses in children or from cord blood of infants born to overweight/obese mothers. In all cases, there was a tendency towards decreased production of innate cytokine Type I Interferon and TNFα, however there was no significant negative correlation. Interestingly, high maternal BMI showed weak and moderate positive correlation with IL-12p70 and IFNγ, respectively, in response to CNA stimulation. This study demonstrates that future adjuvants can be tailored for these populations through the use of activators of CNA sensors

Proportion of Concentrate in the Diet of Early Lactation Dairy Cows has Contrasting effects on Circulating Leukocyte Global Transcriptomic Profiles, Health and Fertility according to Parity

Publication history: Accepted - 16 December 2022; Published online - 20 December 2022The functionality of circulating leukocytes in dairy cows is suppressed after calving, with negative energy balance as a risk factor. Leukocyte transcriptomic profiles were compared separately in 44 multiparous (MP) and 18 primiparous (PP) Holstein–Friesian cows receiving diets differing in concentrate proportion to test whether immune dysfunction could be mitigated by appropriate nutrition. After calving, cows were offered either (1) low concentrate (LC); (2) medium concentrate (MC) or (3) high concentrate (HC) diets with proportions of concentrate to grass silage of 30%:70%, 50%:50% and 70%:30%, respectively. Cow phenotype data collected included circulating metabolites, milk yield and health and fertility records. RNA sequencing of circulating leukocytes at 14 days in milk was performed. The HC diet improved energy balance in both age groups. There were more differentially expressed genes in PP than MP cows (460 vs. 173, HC vs. LC comparison) with few overlaps. The MP cows on the LC diet showed upregulation of the complement and coagulation cascade and innate immune defence mechanisms against pathogens and had a trend of more cases of mastitis and poorer fertility. In contrast, the PP cows on the HC diet showed greater immune responses based on both gene expression and phenotypic data and longer interval of calving to conception. The leukocytes of MP and PP cows therefore responded differentially to the diets between age, nutrient supply and immunity affecting their health and subsequent fertility.This project received funding from the European Union’s Seventh Framework Programme (EU FP7, Brussels, Belgium) for research, technological development, and demonstration under grant agreement no. 613689 (GplusE).

Functional Capacity Assessed by the Map Task in Individuals at Clinical High-Risk for Psychosis

Recent studies have recognized that signs of functional disability in schizophrenia are evident in early phases of the disorder, and, as a result, can potentially serve as vulnerability markers of future illness. However, functional measures in the psychosis prodrome have focused exclusively on real-world achievements, rather than on the skills required to carry-out a particular real-world function (ie, capacity). Despite growing evidence that diminished capacity is critical to the etiology of the established disorder, virtually no attention has been directed towards assessing functional capacity in the pre-illness stages. In the present study, we introduce the Map task, a measure to assess functional capacity in adolescent and young-adult high-risk populations
