Show moreFuture generations of humans and our non-human relatives will face the environmental consequences of a human-first approach towards development. The transition from fossil fuels towards renewable energy sources represents a deviation in behavior back to the eco-centric principles practiced by our ancestors for millennia. Renewable energy technology and infrastructure development often faces barriers within communities for numerous reasons. Using Native Nation Building theory from the community development literature as a foundation, this thesis examines the perspectives of tribal affiliated individuals for initiating renewable energy development in a Michigan tribal community. The study relies on 14 semi-structured interviews with tribal citizens and employees in one Native American community that has repeatedly expressed interest in developing renewable energy infrastructure projects on tribal lands. Through thematic analysis, observations, and personal experience, I show how both required elements of Native Nation Building have not been fulfilled and barriers to development are a result of conditions witnessed during repeated site visits to conduct qualitative interviews. This research makes it clear that the barriers identified by academic literature are overshadowed by the conditions witnessed while interacting with tribal community members. In addition to participatory based action research strategies, I argue that addressing poor community conditions is necessary while attempting community development projects focused on renewable energy transitions.

The overwintering success of winter wheat (Triticum aestivum L.) along with heightened awareness of soil spatial variabilities have growers focusing more on season-long soil nutrient availability. Field trials were initiated in Richville and Lansing, MI to evaluate the effects of autumn starter, spring nitrogen (N), and varietal stature on winter wheat plant growth, grain yield, and expected net return.

Show moreThe overwintering success of winter wheat (Triticum aestivum L.) along with heightened awareness of soil spatial variabilities have growers focusing more on season-long soil nutrient availability. Field trials were initiated in Richville and Lansing, MI to evaluate the effects of autumn starter, spring nitrogen (N), and varietal stature on winter wheat plant growth, grain yield, and expected net return. Application of autumn starter (i.e., mid and high treatments compared to no autumn starter) increased grain and straw yield in all site years. Autumn starter and spring N applications indicate above-recommended spring N did not compensate for the lack of autumn-applied starter during establishment. Mid-rate autumn starter was the most economical option under the current environmental conditions to maximize grain and straw yield in soft red and white winter wheat. When fertilizing for straw production, varieties may respond to greater rates of autumn starter, but yield increases did not result in increased profitability. One of the more severe foliar pathogens capable of causing damage to sugarbeet is Cercospora beticola, the causal pathogen of Cercospora leaf spot (CLS). When not managed appropriately, CLS can reduce sugarbeet yield 40%. Management strategies including boron (B)-containing compounds have shown to have fungistatic properties with the ability to reduce disease severity in the field. Field studies were established to investigate the effects of foliar applied B on sugarbeet plant health and CLS disease severity. Application of foliar B did not reduce CLS in field environments across site years. Complementary in vitro studies were conducted to test B effects on C. beticola mycelial growth. Cercospora beticola EC50 values were 772-876 mg kg-1 for sodium tetraborate. Reduced control options, increased CLS resistance, and increase B requirement of sugarbeet enhance the need for further evaluation of alternative control. In-field evaluation of various B timing, increased B concentration, and addition of B-containing compounds may contribute to future CLS control.

Show moreDarkness, water, wind, and tragedy. The Great Cyclone of 1970 swept into East Pakistan on the evening of November 12, its surging waters wiping out whole villages. The final death toll is still unknown. But for one of the first times in history, relief aid came pouring in from around the world. Several countries participated in short term relief to provide food, water purification, and shelter to people within the hardest hit areas. Pakistan implemented an agricultural rehabilitation plan to provide food and agricultural aid to see the agrarian society through until the next harvest. Exactly where much of this aid went is not clear. Select aspects of the short- and medium-term aid effort that were connected to geographic locations were mapped. Maps were created from British and American accounts depicting national relief efforts and the international helicopter relief assistance. This paper also used post-cyclone surveys and aid reports to map the distribution of agricultural aid. It also discusses three of the factors that were considered when allocating the agricultural aid: season, manpower, and supplies and equipment. This paper also conducts content analysis of news coverage of the relief effort during this time using newspaper articles from the two largest international contributors: the United Kingdom and the United States. The purpose of this paper is to locate the cyclone and subsequent relief efforts in their geographic and historical context by mapping and analyzing the relief efforts and their contemporary perception.

Show moreThere are many positive influences from greenspaces which are even more crucial in large urban cities such as Detroit, Michigan. The abandoned area of the old Belle Isle Park Zoo has been the subject of numerous redevelopment proposals. However, there is a gap in what designers have done and what this research proposes, which is that previous designs lacked community engagement. The purpose of this study is to demonstrate the importance and value in including community engagement into design choices. With a series of public workshops with stakeholders, landscape performance research has been adopted to assess the impact of the final design proposal. The success of a final design after community engagement aims to promote the use of community engagement in design as a beneficial and necessary factor when installing public space developments. The study will utilize the abandoned zoo space in Belle Isle Park to demonstrate that the community will benefit more from having input in what changes are made to their own community spaces while still allowing the designers room to implement environmental and socioeconomic beneficial tactics.

However, we do not know how injury-related fear is associated with other meaningful psychological responses to injury, or how patient perceptions of these psychological responses relate to their rehabilitation experiences. The purpose of this cross-sectional, explanatory sequential mixed-methods study was to explore how perceptions of self-determined motivation, athlete burnout, and injury-related fear affected psychological experiences during ACLR rehabilitation in patients between 4- and 6-months post-ACLR. 13 participants were recruited and completed questionnaires measuring self-determined motivation, athlete burnout, perceived stress, and injury-related fear. A sub-sample of 5 participants participated in a semi-structured interview to further underline patient experiences during ACLR rehabilitation. A strong, positive relationship was observed between perceived stress and injury-related fear (rho = 0.70, p = 0.008). Thematic analysis revealed five themes related to the rehabilitation experience: 1) struggling with the recovery process, 2) acknowledging negative emotional states, 3) drive to return to sport and normal life, 4) understanding and finding purpose in rehabilitation, and 5) successfully navigating the recovery process. These preliminary data suggest that negative emotional states, such as injury-related fear and athlete burnout, may be related to self-determined motivation and perceived stress after ACLR.

Mesotrione is sold alone or in premixture with other herbicides; bicyclopyrone is sold only in premixtures. There is limited data available on the response of other crops planted into fields where these herbicides were applied. Greenhouse and field experiments were conducted to evaluate alfalfa, cucumber, black and kidney bean, and sugarbeet response to bicyclopyrone and mesotrione. In the greenhouse, cucumber, black bean, kidney bean, and sugarbeet were more sensitive to mesotrione compared with bicyclopyrone. Sugarbeet was the most sensitive to both bicyclopyrone and mesotrione followed by alfalfa. Cucumbers were the most tolerant to bicyclopyrone and mesotrione followed by kidney bean and black bean. In field research, bicyclopyrone at 50 and 100 g ha-1 (1 and 2X rate), and mesotrione at 210 g ha-1 were applied in early June to V4 corn at two locations in 2015 and 2016. The following spring, alfalfa and sugarbeet were planted in mid-April and cucumber and dry edible bean in early-June and crop response was measured. In 2016, injury in all crops was less than 20%, regardless of herbicide treatment at either location. In 2017 at East Lansing, sugarbeet was severely injured and did not survive where mesotrione was applied the previous year. Sugarbeet and kidney bean injury was 15 and 5%, respectively from the 2X rate of bicyclopyrone. Neither mesotrione or bicyclopyrone affected crop growth or yield at Richville in 2017. Soil pH was 6.0 and soil organic matter was 4.2 to 4.5% at East Lansing and soil pH was 7.8 and soil organic matter 2.6% at Richville. While there were differences in soils at the two locations, rainfall within the first 30 days following application contributed to differences in herbicide carryover. At East Lansing, rainfall was 20.5 and 2.8 cm within the first 30 days following application in 2015 and 2016, respectively, contributing to more herbicide carryover in the 2017 growing season than in the 2016 growing season. Rainfall at Richville had a 60% reduction in precipitation within the first 30 days however, no herbicide carryover was experienced. From this research it appears that alfalfa, dry bean or cucumber can be planted the year following mesotrione or bicyclopyrone application. However, sugarbeet should not be planted the year following applications of mesotrione or bicyclopyrone.

Show moreTough love is often discussed in sport, but there is not a clear understanding of what tough love is, which tough love behaviors are commonly used by coaches and how effective they are, or which factors may influence the effectiveness of tough love strategies. Additionally, tough love may cross over into abuse or maltreatment if approached incorrectly. The purpose of this study was to propose a definition of tough love coaching, identify effective tough love strategies, determine whether tough love coaching can be inappropriate or harmful to the athlete, and identify individual factors that influence the way in which tough love is received by athletes. This study adopted a basic interpretive approach to qualitative research by using semi-structured interviews to investigate athletes’ experiences with and feelings toward tough love in sport. Specifically, in-depth interviews were conducted with 12 current and former athletes (three males, nine females) ranging in age from 18 to 27 who had or were participating in a variety of sports. Thematic analysis was conducted on the transcribed interviews to identify relevant themes, subthemes and categories in the data. Four major results were found. First, a definition of tough love coaching was proposed. Second, examples of effective, ineffective, and harmful tough love strategies were provided. Third, factors perceved to influence tough love’s effectiveness were identified, including the coach-athlete relationship, coach demographics, athlete characteristics, sport demographics, encouragement and support, clear feedback, frequency of use, motivational climate, and privacy. Fourth, the “line” between tough love and harmful or abusive coaching was identified. Results are discussed relative to the coaching feedback and approaches as well as maltreatment in sport reseach literature.

Show moreCOVID-19 pandemic news has become popular and topical content for the last couple of years. And the wide usage of social media across the globe makes it easy to share information, including misinformation, about COVID-19. Although sharing news on social media has been actively studied in most western countries, little attempt has been made to look into the issue from the perspectives of developing countries where the amount of social media use has been increasing enormously over the last years. Besides, almost nothing is known about the social media users’ choice of a particular platform when they decide to share information and misinformation, especially within the context of the COVID-19 pandemic. Therefore, this master’s thesis explored how motivation factors Kazakhstani people follow when sharing COVID-19 news shape their decision to share COVID-19 news on specific social media platforms and their COVID-19 misinformation sharing patterns.The study used a quantitative research method approach, surveying 288 people from Kazakhstan over 18 years old.

Show moreA growing body of literature suggests that how much support TGD individuals experience in the places they live, including their present context and context of origin, can influence their wellbeing. Other research about physical health has found exposure to stressors has physiological effects on sexual and gender minority people, which can be measured through allostatic load (a selection of multiple physiological indicators that reflects “wear and tear” on the body; AL). Research on mental health has also indicated that TGD individuals are at higher risk of depression and anxiety. TGD populations also have unique resilience factors that are important to consider, such as pride and community connectedness, which may influence health outcomes. This study used latent class analysis to examine how individuals clustered based on current and past levels of contextual support, and then examined the relationship between these classes and AL, depression, and anxiety, including whether pride and community connectedness moderated these relationships. Contextual support across the lifetime was also examined as a continuous variable. Participants either had lived consistently in contexts with high levels of support (High Support class), had moved from contexts with low levels of support to high levels of support (Low to High Support class), or had consistently lived in contexts with low levels of support (Low Support class). Individuals in the Low Support class had lower levels of AL compared to their peers in the High Support class. There were no associations between class and depression and anxiety, and there were no moderating effects of community connectedness or pride. This study suggests that contextual support may not influence depression and anxiety among TGD people, but that lower levels of support may actually correlate with decreased AL.

Show morePuberty is a period of increased risk for the development of binge eating in female adolescents. Studies thus far have examined changes in genetic factors and personality characteristics that could contribute to increased risk, but none have examined parenting practices that are known to change across development and significantly contribute to youth outcomes (e.g., parent-child conflict, parental warmth, parental overprotection). The current study examines whether interactions between puberty and parenting predict higher levels of binge eating symptoms during/after puberty in female youth. Analyses used cross-sectional data in a sample of 999 female youth (ages 8-16) and their parents from the Michigan State University Twin Registry. Youth provided ratings of binge eating, eating in the absence of hunger, emotional eating, perceived parental care and overprotection. and pubertal development. Both youth and parents provided ratings of parent-child conflict. Although higher levels of parental overprotection and conflict, and lower levels of parental care, significantly predicted all binge eating measures, none of the associations were significantly moderated by pubertal development or age. The quality of the parent-child relationship is significantly associated with binge eating in female pre-adolescents and adolescents regardless of developmental stage, highlighting the need for targeting harmful parenting strategies during adolescent eating disorder intervention.

Show moreThe abandoned industrial crisis in Michigan, USA calls for the redevelopment of abandoned industrial site areas into functioning public spaces. These neglected spaces develop negative impacts on the surrounding communities regarding aesthetic, safety, economic, and environmental issues. The purpose of this study is to examine the redevelopment of an underused site, especially featuring an industrial site element, and the effects on the nearby community by applying quantitative measures. The Michigan Central Station in Detroit, Michigan, USA was selected as a case study. Landscape performance research was applied to quantitively analyze the environmental, social and economic benefits of reclaiming abandoned industrial sites and their inner elements. In this research, findings showed the case study redesign resulted in positive environmental impacts. These impacts included: expanded areas of ecologically valuable land, increases in carbon sequestration, increases in retained stormwater, the use of recycled content and reductions in sulfur dioxide. The case study redevelopment showed impacts on the surrounding economics through savings on water treatment cost through stormwater retention, increases in property values, and job creation. Furthermore, the redesign also impacted social aspects for the surrounding areas including increases in the area of proposed gathering space, safety enhancements, additions of sidewalks and bike lanes, and increases in the area of public open space. In addition, the major findings support the benefits of public physical health by promoting outdoor activities. The findings of this study will help designers and urban planners to see the value in reusing existing industrial sites instead of undergoing the harmful demolition process and eventually lead to a more sustainable community design.

Show moreWhen observers view a perceptually bistable stimulus, their perception changes stochastically. Various studies have shown across-observer correlations in the percept durations for different bistable stimuli including Necker cube, binocular rivalry (BR) and bistable moving plaids (MP), which suggests a shared mechanism underlying perception in these paradigms. In this project we explore such shared mechanisms by examining what determines whether a given set of bistable perception paradigms will exhibit correlations in percept durations, and also by examining correlations with other perceptual phenomena that do not directly involve bistability. In our first experiment, we hypothesize that the presence or absence of a certain type of motion can influence whether different bistable paradigms will exhibit correlated percept durations. We found that the correlations between some bistable stimuli are strong, but others are fragile and inconsistent, which prevents us from drawing direct conclusions. In the second experiment, we examine whether between-observer variability in cortical inhibition underlies correlated percept durations between binocular rivalry and bistable moving plaid perception. As a behavioral measure of cortical inhibition, we used center-surround suppression of perceived contrast. While we were able to successfully replicate the correlations between bistable paradigms, there was no correlation between center-surround suppression strength and percept durations for any bistable paradigm. Moreover, the results from a mediation analysis indicate that center-surround suppression is not the mediating factor in the correlation between BR and MP, suggesting that cortical inhibition cannot explain the correlation between various bistable paradigms.

Show moreBackground: Relatively little work has quantified associations between prenatal food insecurity and breastfeeding practices; however, understanding the implications of prenatal food insecurity may support food insecurity screening recommendations during prenatal care. Therefore, the purpose of this study was to investigate associations between prenatal food insecurity and breastfeeding initiation and duration until 3 months postpartum. Method: This study utilized data from a prospective Michigan pregnancy cohort. Women were recruited during their first prenatal visit with planned follow-up through early childhood. Prenatal food insecurity was assessed during pregnancy, and breastfeeding initiation and duration were assessed at the 3-month postpartum visit. Multiple logistic regression models were used to evaluate associations between prenatal food insecurity and the two primary outcomes: breastfeeding initiation and breastfeeding status at 3-months postpartum. Cox proportional hazard ratios were used to assess differences in the risk of breastfeeding cessation until 3 months postpartum by food insecurity status. An adversity index was created to stratify women into higher- and lower-risk groups for not breastfeeding. Associations between food insecurity and breastfeeding at 3 months postpartum (yes/no) were assessed via Fisher’s Exact test within each group. Results: In the unadjusted models, women who reported food insecurity during pregnancy were less likely to initiate breastfeeding (OR = 0.39; 95% CI: 0.21-0.69) and continue breastfeeding until 3 months postpartum (OR = 0.35; 95% CI: 0.20-0.61) compared to food secure women, but the associations were no longer significant after adjustment for sociodemographic and health-related factors. Prenatal food insecurity was not associated with breastfeeding at 3 months postpartum in analyses stratified into high- and low-adversity groups. Conclusions: Prenatal food insecurity is a strong predictor of breastfeeding practices. Though not significantly associated with breastfeeding practices after adjustment, screening for prenatal food insecurity may help clinicians identify women who may need more supports to initiate and maintain breastfeeding.

This paper aims to offer a better understanding of the state of the literature on assessing the urban environment and health through mapping the field of research through a scoping review and illuminating emerging trends and future research using keyword frequency and bibliometric analysis. Uniquely, this study drew 495 articles from four distinct journal databases (PubMed, Scopus, Web of Science, and ProQuest), whereas traditional bibliometric analyses draw from a single source. By drawing from a broader base of knowledge, this study offers a more holistic view of the trends in the field of research on the connection between urban environments and well-being to better identify future research pathways. The results show trends of a consistent increase in research on the topic over the last decade. Research published on this topic is fragmented, with consistent but isolated focus on physical health, mental health, and environmental characteristics. Overall, in this field, physical health is most often assessed in relationship to the urban built environment, while mental health is most often assessed in connection to the urban natural environment. This paper also provides information on influential authors in this field of research. This study concludes by highlighting gaps and making recommendations for future research in the field. Prominent gaps are related to using interdisciplinary and scalable approaches to understanding the relationship between urban environments and overall well-being.

This blurriness of understanding promoted the opportunity for research, and with the availability of new and improved technology, an opportunity for high accuracy analysis also arises. This study showed that ice ridge location corresponded to the bar and trough system in lakebed morphology, rather than just a nearshore bar or trough. Along with that, the ice presence lowered the overall elevation of the lakebed profile, and this promoted erosion throughout the remainder of the study period. During the entirety of the research study period, the most change that was documented was found between August and November 2020 due to a large, recoded storm event that moved through the study location.

Show moreThere is limited empirical evidence on how the growth of large- and medium-scale farms is affecting employment outcomes across the whole agricultural sector in developing countries, and especially among young people (age 15-35 years). A priori, it is impossible to determine how medium- and large-scale farms affect employment for young people in agriculture. Using employment data for young people in Tanzania, this study examines whether increases in the region-level share of cropping households that are medium- and large-scale farms (MLSFs) improve or worsen agricultural employment outcomes for young people. The outcomes include: (i) employment in crop/livestock production on own farm; (ii) self-employment in agribusiness activities and (iv) employment in agriculture via any of the first three categories above.Correlated random effects probit model results suggest that the growth of medium-scale farms is associated with reductions in the participation of young people in the production of crops/livestock on their own or their family’s farms. It is also associated with a reduction in the employment of young people in the agricultural sector overall. The growth of large-scale farms is associated with an increase in self-employment in agriculture by young people. The government needs to be cognizant of the effects of different farm sizes on employment. Medium-scale farms may not be an avenue to improve young people’s involvement in agriculture. However, large-scale farm expansion may improve young adult’s employment in agricultural employment

This study examines experiences of discrimination in a sample of 158 TGD individuals and the relationship between discrimination, mental health, and social disadvantage. The current study used latent class analysis (LCA) to separate participants into classes based on their experiences of discrimination based on their identities: Class 1 (All Types)- had the highest probability of endorsing all types of discrimination experiences, Class 2 (Few Types)- had a low probability of endorsing discrimination experiences based on their identity, and Class 3 (SGM Types)- had a high probability of endorsing discrimination experiences related to gender identity, gender presentation, and sexuality, but a low probability of endorsing discrimination based on race and ancestry. Class membership did not significantly predict mental health outcomes; however, social disadvantage was a predictor of mental health outcomes. Thus, social disadvantage should be systematically addressed to prevent poor mental health outcomes in TGD populations.

Although evidence-based practices (EBPs) have been shown to improve a variety of outcomes for autistic children, they are often inconsistently implemented or not implemented in community settings where many autistic children primarily receive care. One multi-faceted implementation strategy that researchers have developed and tested in a pilot study to support the implementation of EBPs for ASD in community settings is The Autism Community Toolkit: Systems to Measure and Adopt Research-Based...
Show moreAlthough evidence-based practices (EBPs) have been shown to improve a variety of outcomes for autistic children, they are often inconsistently implemented or not implemented in community settings where many autistic children primarily receive care. One multi-faceted implementation strategy that researchers have developed and tested in a pilot study to support the implementation of EBPs for ASD in community settings is The Autism Community Toolkit: Systems to Measure and Adopt Research-Based Treatments (ACT SMART Toolkit). Here, we used a case study approach to assess fidelity to the toolkit during its pilot study (implementation strategy fidelity) using measures of adherence, dose, and participant responsiveness and examined the relationship between implementation strategy fidelity and EBP use in an exploratory analysis. Overall, we found that adherence, dose, and participant responsiveness to the ACT SMART Toolkit were high with some variability by toolkit phase and activity. However, our exploratory analysis was ultimately unequipped to evaluate the relationship between increased fidelity and increased EBP use given the limited sample size of the pilot study. Our case study evaluation provides one of the first models of considering fidelity in the context of multi-faceted implementation strategies as well as important insights into potential core and peripheral components of the ACT SMART Toolkit.

This thesis focuses on two invasive species, spotted wing drosophila (Drosophila suzukii) and the brown marmorated stink bug (Halyomorpha halys). The first chapter investigates the potential of native parasitoids to increase their developmental success on D. suzukii. Two native parasitoids were subjected to 10 generations of selection on D. suzukii and fitness metrics were measured in generations 0, 3, and 10. Both parasitoid species responded rapidly to selection, reaching peak developmental...
Show moreThis thesis focuses on two invasive species, spotted wing drosophila (Drosophila suzukii) and the brown marmorated stink bug (Halyomorpha halys). The first chapter investigates the potential of native parasitoids to increase their developmental success on D. suzukii. Two native parasitoids were subjected to 10 generations of selection on D. suzukii and fitness metrics were measured in generations 0, 3, and 10. Both parasitoid species responded rapidly to selection, reaching peak developmental success on the novel host within three generations, which they then maintained for seven additional generations. There was no increase in preference towards the novel host or changes in development time or body size associated with adaptation. The sex ratio became less female biased for both parasitoids after three generations of selection but rebounded in one species by generation 10. These results indicate that artificial selection can increase the performance of native parasitoids within a few generations and may be used to improve biocontrol when co-adapted natural enemies of invasive species are not available. The second chapter investigates how the fitness of the adventive parasitoid of H. halys, Trissolcus japonicus, may change in response to intermittent or continuous exposure to a non-target native stink bug species. Acceptance of the native stink bug species did not increase with either intermittent or continuous exposure. However, reproduction on the native host resulted in a significant fitness cost for T. japonicus and compromised the fitness of the parasitoid on its original host species. These results suggest that non-target effects of T. japonicus may remain insignificant in nature given the fitness cost of attacking native species.

For people with Serious Mental Illness (SMI), attendance to behavioral health care services is linked to a an increased probability of recovery and a decreased risk for suicide, involuntary hospitalization, incarceration, mental distress, and preventable mortality. Within the population of people with SMI, women and men who are Black, Indigenous, and other People of Color (BIPoC) are most likely to experience barriers to services and are the least likely groups to attend services.

Show moreFor people with Serious Mental Illness (SMI), attendance to behavioral health care services is linked to a an increased probability of recovery and a decreased risk for suicide, involuntary hospitalization, incarceration, mental distress, and preventable mortality. Within the population of people with SMI, women and men who are Black, Indigenous, and other People of Color (BIPoC) are most likely to experience barriers to services and are the least likely groups to attend services. Thus, most studies examining behavioral health care attendance trends for people with SMI focus on the relationship between marginalized race and/or sex and barriers to service attendance. However, few studies examine the relationship between barriers and attendance among those who occupy multiple marginalized identity groups. This study seeks to fill that gap. Using Multiple Jeopardy theory, which asserts that membership in multiple marginalized groups increases the risk of experiencing negative life events, this study examines the impact of holding multiple marginalized social group identities and of experiencing barriers to attendance on the probability of attending behavioral health services among people with SMI.
