However, unlike their urban coastal peers, many have not addressed or acknowledged climate change. Few existing research projects have explored the reasons why. To begin filling the knowledge gap and understanding the complexities of the rural Florida climate story, this research aims to answer the question: What challenges are preventing rural inland communities in Florida from addressing climate change, and what do they need to overcome them? To characterize these obstacles and identify next steps, a combination of primary (i.e. surveys) and secondary sources from the author, government agencies, scientists, universities, and other expert organizations were analyzed holistically. The four challenges identified include: community sentiment, investment capacity, gaps in climate literacy, and external connections and coordination. These challenges are linked to numerous underlying issues characteristic of rural communities, such as socioeconomic levels, physical and social isolation, the availability of human capital, and cultural values and perceptions. Based on this information, the discussion section reviews how various stakeholders - local governments, community members, and external supporting agents - can actively curtail disparities in climate preparedness.","PeriodicalId":278243,"journal":{"name":"UF Journal of Undergraduate Research","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126374267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, only a few works have been reported for biological applications, especially, DNA associated. Contemporary gene-editing science through CRISPR technology is advantageous as all types of nucleic acid chains such as RNA, single-stranded DNA, and double-stranded DNA can be modified. There are numerous reports that base pairs of nucleic acids are nonpolar and 2D perovskites that are capped with aliphatic chains possibly can operate as an optical sensor for detecting a specific sequence of DNA. Here, we demonstrate organic-inorganic halide 2D perovskite’s – capped with eight carbon long aliphatic chains – optical and structural properties. Self-assembly of tin-based perovskites showed near-unity photoluminescence quantum yield but had poor stability in water or ambient condition due to hydrolysis whereas lead-based perovskites showed less PL but were stable in water at high concentration. 2D perovskites’ unique multiple emission peaks at different wavelengths, water stability, and intensity discrepancy when conjugated in nucleoside dispersed solution were studied. However, complex multiple directionalities of PL emission, water stability by concentration, minor PL intensity or wavelength discrepancy, and toxicity followed by the lead source for the perovskites are conflicting with robust and convenient detection technique for the DNA.","PeriodicalId":278243,"journal":{"name":"UF Journal of Undergraduate Research","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131400725","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the efficacy of combined pharmacological and nonpharmacological treatments for the management of FM symptoms in a clinical population was assessed. Participants were injected with 4x5 mL 1% lidocaine HCl solution and given education materials and support on increasing their daily steps walked and to engage in mindfulness techniques to reduce their overall pain and accompanying symptoms of their condition. Participants self-reported pain intensity, unpleasantness, anxiety, fatigue, and depression three days prior to and after each injection. Overall ratings of pain intensity and unpleasantness showed statistically significant reductions of 34.7 and 47.2 percent respectively with the combined use of treatments. Additionally, fatigue levels had a significant decrease but depression and anxiety ratings were not significantly modified by this treatment modality. Patients who had a greater adherence to their protocol had an improved pain relief when compared to others. These results suggest that the use of a combination treatment method for FM in a clinical setting and when used in combination is effective. This pilot study can be used as a model for future randomized controlled studies on comprehensive treatments for FM.

Participatory arts interventions are popular to address wellbeing. Participatory drum circles can lead to social resilience, emotional completeness, and mental health benefits. The literature in the field of arts in health demonstrate the specific ways a drum circle may affect wellbeing through socialization, rhythmic entrainment, and expression. Although there are many great resources, many lack the specific tools to facilitate a drum circles as it pertains to specific technique and styles often utilized in percussion in the field of arts in health. \u0000Methods: The project used a mixed methods research design. A convergent mixed methods design will be used to collect quantitative data from the Warwick Edinburgh Mental Wellbeing Scale and the qualitative data will be received from a focus group. The results will be compared with the hopes of yielding similar themes. \u0000Results: The results of the Warwick Edinburgh Mental Wellbeing scale demonstrate an increase of the average wellbeing score after the four-week intervention by 2.88 points. The focus group’s final themes were 1) the core of the drum circle is driven from the facilitator fostering a strong sense of community that supports being inclusionary, respectful, and social; 2) Learning new skills in a community group benefits participants confidence because a) the curriculum progresses naturally and easily and b) rhythm is an innate and natural part of everyday life for individuals, making drum circles more comfortable.","PeriodicalId":278243,"journal":{"name":"UF Journal of Undergraduate Research","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129357180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Outdoor therapies have been used as treatments for mental health for years, so the researchers investigated if stargazing has the potential to have the same benefits. Rather than surveying people on how often they stargaze, the researchers used light pollution data as a metric for the ability of a region to stargaze. The light pollution data was gathered from the Visible Infrared Imaging Radiometer Suite (VIIRS) and the mental health data was collected from a survey conducted by the Substance Abuse and Mental Health Services Administration (SAMHSA). All fifty states were stratified based on light pollution and ten were chosen for analysis. From these states, the number of people with mental illness, number of people who received mental illness treatment, and number of attempted suicides were all considered. Linear regression was performed for these three metrics against light pollution. Overall, the correlation coefficient is too low to confidently establish correlation. Further research and different methods are required to determine the existence of a correlation.","PeriodicalId":278243,"journal":{"name":"UF Journal of Undergraduate Research","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128005594","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Evidence shows that healthcare professionals who work in EDs are more prone to violence from patients and visitors than those working in other healthcare settings. While many studies have highlighted organizational and operational policies to minimize the risk of violence against healthcare workers, very few studies have focused on the role of facility design. This research aimed to (1) gain an understanding of environmental design features in EDs that may impact the occurrence of violet events, and (2) propose potential environmental design scenarios for future examination of ED design through primary research. Peer-reviewed and gray literature on ED design were reviewed, and case examples of ED facility design projects were identified from online sources and were spatially analyzed. Findings from the literature suggested that entry zones of EDs, including entrance doors and vestibules for walk-in patients, reception areas/desks, and waiting areas are associated with the most security issues. Based on this finding, the spatial analysis was limited to the entry zones. The design examples were categorized based on their spatial patterns and visibility properties. This typology of entry layouts helped with developing three design scenarios with different levels of visibility. The design scenarios represent the most common layouts of entry design in ED facilities. A walk-through video of each scenario is developed for future research. A future study can identify the perceived security level of each scenario by presenting them to healthcare workers and security professionals working in EDs. This research highlights the importance of interior environmental design in improving security and reducing the risk of violent behavior against healthcare workers in EDs.","PeriodicalId":278243,"journal":{"name":"UF Journal of Undergraduate Research","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116574318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The primary purpose of this research was to determine whether the businesses GrubHub, UberEats, and DoorDash were successful in facilitating growth with the seemingly advantageous circumstances provided by the national emergency. Financial performance was evaluated utilizing economic key performance indicators (KPIs) for revenue, liquidity, and profitability. All data was collected from eight quarterly income statements and balance sheets from 2019 and 2020 for each company. Averages of the KPIs were computed for cumulative quarters prior to and including March 2020, after the announcement of COVID-19 restrictions, and the quarters subsequent to that date range; the mean values were then compared across both time periods. Results suggest an overall positive trend for DoorDash for all metrics and negative trend in terms of liquidity for UberEats and GrubHub. Furthermore, revenues for all three platforms possessed an increased expansion rate during COVID-19 within a range of 9.07-12.60%. Implications of this experiment include possible research of non-food delivery platforms that operate based on the sale of virtual products during the pandemic or further exploration of such companies as COVID-19 begins to subside.","PeriodicalId":278243,"journal":{"name":"UF Journal of Undergraduate Research","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129012972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
