Great form through architecture i a goal we strive to reach. In the educational world, a professor assigns a topic or project. Design a velodrome, a house, a museum. These are formal ideas with formal identities that allow for shaping, pushing and pulling and, our hope, some innovation. The finished design is theoretically meant to be functional and real
The Primacy of Openness in Ecological Complexity Theory
Five principles are at the foundation of complex systems theory: emergence, openness, contingency, historicity, and indeterminacy. Of those five, the principle of emergence is easily the most prevalent. Simply put, emergence refers to the idea that some wholes cannot be properly accounted for by appealing to individual explanations of the parts that compose it. In ecological complexity theory, the principle of emergence is strongly associated with the self-organizing feedbacks that often identify the structural framework of ecosystems.
Within the last half century, the intense focus on the principle of emergence has engendered the development of many conceptual distinctions that have importantly contributed to explanations of ecological patterns and ideas about environmental management and restoration. I argue, however, that ecological complexity theory has become somewhat stagnant and myopic in its devout commitment to the principle of emergence.
This dissertation highlights the issue of ecological complexity theory’s overreliance on the principle of emergence by investigating the role of the principle of openness. I argue the reverse of what is typically maintained in the literature – the principle of openness possesses metaphysical, epistemological, and ethical primacy. By beginning with the principle of openness and working towards the use of the principle of emergence in explanations of ecological phenomena, I urge greater appreciation for an ecosystem’s complete causal narrative and a reconsideration of the formulation and carrying out of future management and restoration practices and policies
Place-bo-burbi-agri-culture to Place-ive-ianure Methods for place making: Increasing value with representation
This thesis examines how to turn space into place. In the digital age, place is more important than ever before. Around the world communities are dealing with the issue of placelessness. The food system has become standardized and suburbia has become a monotonous repetition in cities across the country. As people search for a sense of place in their communities, creation of place can be a tool for exploring these issues. Through experience, individuals can begin to understand and become aware of the place they call home. This thesis discusses three methods for the comprehension of place. They are narrative writing, deep mapping, and photography. These methods provide a catalyst to investigate how a person’s personal experiences, the history of a place, and visual representations of a place can help create a sense of place that can carry into the future
Comparison Of Cognitive Performance Following One Hour Of Passive Heating Or Walking In Older Adults: A Preliminary Analysis
Moderate-intensity exercise increases measures of cognitive performance such as working memory and cognitive flexibility. Hyperthermia can result in declines in cognitive performance through reduced motor function and response inhibition. However, these results have been observed during cognitive performance in the heat while core temperatures remain elevated. Heat therapy may promote improvements in cognitive function after treatment similar to exercise training by inducing a stress-related response. The purpose of this study was to compare cognitive performance immediately following one hour of moderate-intensity aerobic exercise or one hour of whole-body passive heating. METHODS: Four adults (age: 67.3 + 3.3 years, BMI: 29.0 + 5.4 kg/m2, 2 female) participated in a randomized repeated measures study. Participants completed either one hour of moderate intensity walking on a treadmill (TM; 65-75% age-predicted maximum heart rate) or one hour of seated passive heating (HEAT) in a controlled environmental heat chamber (32-35 degrees Celsius, \u3c 40% humidity). Cognitive performance was measured using computerized software (Automated Neuropsychological Assessment Metrics, ANAM, Vista LifeSciences, Inc.), which provides objective measures of cognitive performance through a variety of test batteries designed to measure variables such as motor coordination, cognitive flexibility, and response inhibition. Variables were analyzed as a change in score from the familiarization exam (pre- or post-treatment minus – baseline) to minimize the learning effect. RESULTS: No differences between measures of motor coordination (TM: 6 + 12.7 vs. 5 + 12.7; HEAT: 0 + 1.4 vs. -1 + 1.4), cognitive flexibility (TM: -1 + 1.4 vs. 1.5 + 0.7; HEAT: 3.5 + 0.7 vs. 3.5 + 0.7), or response inhibition (TM: 17 + 22.6 vs. 23.5 + 23.3; HEAT: 1.5 + 2.1 vs. 8 + 2.8) were found following either treatment. CONCLUSION: One bout of moderate intensity aerobic exercise or whole-body passive heating does not impair cognitive performance. In addition, one hour of passive heating does not result in decreased cognitive performance in older adults. Post-hyperthermic stress response did not impair cognitive function

Anaerobic Performance in Female Collegiate Wrestlers During Ovulation Versus the Mid-luteal Phase of the Menstrual Cycle: A Pilot Study
Anaerobic performance may vary during different phases of the menstrual cycle. The greatest differences occur between the late-follicular phase (i.e., ovulation) and the mid-luteal phase. Optimal anaerobic performance may be observed during the mid-luteal phase. PURPOSE: To explore differences in upper and lower body anaerobic performance during ovulation versus the mid-luteal phase of the menstrual cycle in collegiate female wrestlers. METHODS: Six female collegiate wrestlers (age = 18.6 ± 0.2 yrs; height = 165.0 ± 0.5 cm; body mass = 79.7 ± 9.6 kg; lean body mass = 45.6 ± 2.8 kg; % body fat = 31.4 ± 6.6%) performed both upper and lower body Wingate tests, each lasting 30 seconds, during the ovulation and the mid-luteal phases of the menstrual cycle. Upper and lower body tests were performed 24 hours apart. Menstrual cycle phases were determined by calendar tracking, reverse estimation of ovulation, and administration of a urinary luteinizing hormone test assessed daily until positive results indicated ovulation. Lower body power was measured using a Velotron cycle ergometer, with a resistance of 0.075 kg/kg applied after a 5-second sprint at a resistance of 1 kg (50 W). Peak power (W) and relative power (W/kg) were measured. Upper body power was measured using a Monark hand ergometer with a 0.045 kg/kg resistance applied after a 5-second sprint at a resistance of 0.5 kg (25 W). Peak power (W) and relative power (W/kg) was calculated using rotation count, weight applied, and distance per rotation. Paired t-tests were used to analyze differences in means during the ovulation vs mid-luteal phases with a significance level of 0.05. RESULTS: There were no significant differences between trials for any variables measured. Lower body peak power (W) was 848.3 ± 126.1W vs 855.0 ± 143.9W. Lower body relative power (W/kg) was 11.8 ± 0.7W/kg vs 11.9 ± 0.8W/kg. Upper body peak power (W) was 162.1 ± 29.6 vs 160.2 ± 13.2W. Upper body relative power (W/kg) was 2.3 ± 0.4W/kg vs 2.2 ± 0.2W/kg. CONCLUSION: There may not be an optimal timing of significantly increased anaerobic performance in regard to menstrual phase in these wrestlers

Both/And: Mixed methods analysis of network composition, communication patterns, and socio-economic support within social networks of transgender women involved in sex work in Lima, Peru
IntroductionSocial networks contribute to normative reinforcement of HIV prevention strategies, knowledge sharing, and social capital, but little research has characterized the social networks of transgender women (TW) in Latin America. We conducted a mixed methods analysis of three network clusters of TW in Lima, Peru, to evaluate network composition, types of support exchanged, and patterns of communication.MethodsWe recruited TW residing in or affiliated with three "casas trans" (houses shared among TW) in Lima between April-May 2018. Eligible participants were 18 or older, self-reported HIV-negative, and reported recent intercourse with a cis-male partner. Participants completed demographic questionnaires, social network interviews, and semi-structured interviews to assess egocentric network structures, support exchanged, and communication patterns. Quantitative and qualitative data were analyzed using Stata v14.1 and Atlas.ti, respectively.ResultsOf 20 TW, median age was 26 years and 100% reported involvement in commercial sex work. Respondents identified 161 individuals they interacted with in the past month (alters), of whom 33% were TW and 52% family members. 70% of respondents reported receiving emotional support from family, while 30% received financial support and instrumental support from family. Of the 13 (65%) respondents who nominated someone as a source of HIV prevention support (HPS), the majority (69%) nominated other TW. In a GEE regression analysis adjusted for respondent education and region of birth, being a family member was associated with lower likelihood of providing financial support (aOR 0.21, CI 0.08-0.54), instrumental support (aOR 0.16, CI 0.06-0.39), and HPS (aOR 0.18, CI 0.05-0.64). In qualitative interviews, most respondents identified a cis-female family member as their most trusted and closest network member, but other TW were more often considered sources of day-to-day support, including HPS.ConclusionTW have diverse social networks where other TW are key sources of knowledge sharing and support, and family members may also represent important and influential components. Within these complex networks, TW may selectively solicit and provide support from different network alters according to specific contexts and needs. HIV prevention messaging could consider incorporating network-based interventions with TW community input and outreach efforts for supportive family members
Monetary Cost of the MyPlate Diet in Young Adults: Higher Expenses Associated with Increased Fruit and Vegetable Consumption
Background. Cost is a commonly reported barrier to healthy eating. This is a secondary research analysis designed to examine the food expenditures of young adults on a university campus following the United States Department of Agriculture (USDA) MyPlate guidelines for fruits and vegetables. Methods. Meal receipts and dietary intake were recorded weekly. Anthropometrics and clinical assessments were recorded before intervention. Researchers rated compliance based on the participant’s dietary food log, receipt matching, food pictures, and reports during weekly 1-hour consultations. Results. Fifty-three young adults (18–30 years old) at-risk of, or diagnosed with, metabolic syndrome (MetS) were enrolled in the study, with 10 excluded (n = 43) from analyses due to enrollment in a fixed cost university campus dining meal plan. A two sample t-test assessed differences in food costs and regression analysis determined associations between food cost and diet compliance while controlling for confounding factors of age, sex, and body mass index (BMI). Diet compliant subjects (n = 38) had higher weekly food cost at 66.24 (). A regression analysis controlling for age, sex, BMI, and geographical region also indicated cost differences based on diet compliance (). Conclusion. Results indicate an ∼$29.00 per week increase in food cost when eating the recommended amount of fruit and vegetables. These findings can contribute to research incentive design, program planning cost, and determining effective interventions to improve diet in this population
