Indiana University-Purdue University Indianapolis (IUPUI) / Educating a sufficient nursing workforce to provide high quality, compassionate, and ethical care to an increasingly diverse population is an ongoing challenge and opportunity for nurse educators. Current literature highlights the importance of engaging students in learning to strengthen student achievements. Fostering student engagement within nursing courses is particularly important. Grit (consistency of interest and perseverance of effort) is a factor that may be associated with student course engagement. Demographic characteristics of age, gender, race/ethnicity, prior education, degree program, and self-reported grade point average (GPA) also may be factors associated with student course engagement. Guided by a conceptual model derived from the literature, the purpose of this study was to determine whether grit and demographic characteristics were associated with student course engagement (skills, emotion, participation/interaction, and performance) within a nursing course. Using an exploratory, descriptive, cross-sectional design, a convenience sample of 97 nursing students in a didactic health assessment course was administered the Student Course Engagement Questionnaire (SCEQ), visual analog scales for student engagement, Grit-S Scale, and a Student Demographic Characteristics form. Using multiple regression, 22% of the variance (21% Adjusted) of total student engagement (SCEQ) was explained by total grit scores (Grit-S) F(1,95) = 26.54, p<.001. Further analyses of student engagement were conducted using the SCEQ subscales and visual analog scales with similar results. Findings provided support for the conceptual model used to guide the study, although replication of the study was recommended across varied learning environments. Findings warrant further study regarding grit as a potential area for the future development of strategies to foster engagement of nursing students in the classroom.

Atualmente, existe uma tendência entre os projetistas brasileiros de valorizar a etapa de tratamento preliminar em projetos de novas estações de tratamento de esgoto (ETE). Neste ensejo foi concebido, construído e estudado um protótipo, em escala plena, de uma unidade composta de separador hidrodinâmico por vórtice (SHV) – empregado como desarenador – e grade fina cilíndrica de fluxo tangencial. Estudos acerca da hidrodinâmica da unidade, fundamentados em ensaios de estímulo-resposta com traçador (sal de cozinha) e simulações computacionais do padrão de escoamento em software de dinâmica dos fluidos computacional, demonstrou que ao se operar a unidade com taxas de aplicação superficial (TAS) de 764 'M POT.3'/'M POT.2'd; 1.146 'M POT.3'/'M POT.2'd e 1.528 'M POT.3'/'M POT.2'd o regime de macro-mistura do padrão de escoamento que se desenvolve no SHV aproximou-se do plug-flow, porém com certo grau de mistura que diminuiu com o aumento da TAS. Nesta pesquisa, foram desenvolvidos dois métodos um para determinação da concentração de areia no esgoto sanitário e outro para determinação da distribuição granulométrica dos grãos dessa areia. Ambos foram empregados na avaliação de desempenho da unidade de tratamento preliminar desenvolvida, que foi realizada na estação elevatória de ETE Jardim das Flores do município de Rio Claro, SP. Durante esta fase da pesquisa, o SHV demonstrou enorme potencialidade na remoção de areia para as TAS de 764 'M POT.3'/'M POT.2'd; 1.146 'M POT.3'/'M POT.2'd e 1.528 'M POT.3'/'M POT.2'd, porquanto, além de não remover significativamente matéria orgânica particulada (medida em termos de concentração de sólidos suspensos voláteis) presentes no esgoto sanitário, a unidade atingiu eficiências de remoção de grãos de areia de tamanho maior ou igual a 200 'mü'm entre 85% e 95%. Entretanto, a grade fina cilíndrica de fluxo tangencial (auto-limpante) revelou-se inviável. / Currently, there is a trend among the brazilian designers of valorizing the preliminary treatment in recently designed wastewater treatment plants (WWTP). In this context, a full scale prototype of a unit made up of a hydrodynamic vortex separator (HVS) – applied as a degritter – and a tangential flux fine screening was designed, built and evaluated. Research about the hydrodynamic of the prototype, based on stimulus-response essays with a salt tracer (sodium chloride) and computational simulations of the flow pattern using the computational fluid dynamic (CFD) software, showed that the macro mixture regime of the flow was similar to a plug-flow when the unit was operated with superficial loading rates (SLR) of 746 'M POT.3'/'M POT.2'd; 1.146 'M POT.3'/'M POT.2'd and 1.528 'M POT.3'/'M POT.2'd, however, the flow presented a certain mixture degree that reduced with the SLR increase. In this research, two methods were developed: one for the determination of grit concentration in sewage and another one for the assessment of grit grading. Both methods were used on the evaluation of the HVS prototype efficiency, which was carried out at Jardim das Flores WWT, in the city of Rio Claro, SP. During this phase of the research, the HVS presented a great potential for grit removal when the SLR of 746 'M POT.3'/'M POT.2'd; 1.146 'M POT.3'/'M POT.2'd and 1.528 'M POT.3'/'M POT.2'd were applied; for the reason that, besides not significantly removing the particulate organic matter present in sewage (measured as volatile suspended solids), the unit achieved grit removal efficiencies in the range of 85% to 95% for grit equal to or large than 200 'mü'm. However, the tangential flux cylindrical fine screening (self cleaning) did not reveal feasibility.

Syftet med den här kvalitativa studien var att studera några specialpedagogers uppfattningar angående mer eller mindre väl fungerande stöd till elever i språk-, skriv- och lässvårigheter i grundskolans senare år. Datamaterialet består av semistrukturerade intervjuer med sju specialpedagoger och har i en första analys tolkats utifrån hermeneutisk metod. Därefter har resultaten i den slutgiltiga analysen förklarats utifrån en teoretisk utgångspunkt som utgörs av två perspektiv på specialpedagogisk verksamhet, enligt Bengt Perssons (2013) modell: det relationella och det kategoriska perspektivet. Resultatet visade på flera faktorer för väl fungerande stöd, där vikten av en tillitsfull relation mellan lärare och elev sticker ut, liksom kunskap om specialpedagogiskt stöd hos lärare samt tidiga insatser såsom pedagogisk kartläggning och digitala verktyg. Samarbete och goda relationer mellan specialpedagog, pedagoger och vårdnadshavare var ytterliga faktorer som bidrog till fungerande stöd medan elevens egen inre vilja och drivkraft; sk grit var en annan intressant framgångsfaktor i uppfattningarna. Faktorer som hittades för mindre väl fungerande stöd var motsatsen; nämligen brist på specialpedagogisk kunskap hos rektorer, lärare men även hos specialpedagoger själva. Värt att uppmärksamma var också avsaknad av studiehandledning på modersmålet samt försummelse att sätta in stöd till elever i avvaktan på utredningsbeslut. Sammanfattningsvis så är de viktigaste resultaten från studien om faktorer för fungerande stöd följande: a) kunskap om specialpedagogiskt stöd hos rektorer och pedagoger, b) goda relationer och samarbete mellan lärare, elever, specialpedagoger och vårdnadshavare, c) tidiga insatser samt d) elevers drivkraft; sk grit och inre vilja att lyckas. Den faktor som utkristalliserades tydligast i studien för mindre väl fungerande stöd var just bristen på specialpedagogisk kunskap hos rektorer och skolans pedagoger, vilket förstärker det omvända resultatet, att specialpedagogisk kunskap hos rektorer och pedagoger är en framgångsfaktor för fungerande stöd. De flesta uppfattningar i resultatet utgick från ett relationellt perspektiv på specialpedagogisk verksamhet. / The aim of this qualitative study was to examine the perceptions of some special educators concerning more or less well functional support to students in language-, writing- and reading difficulties in secondary education. The data consists of semi structured interviews with seven special educators, which has been analyzed according to hermeneutic analysis method in the primary analysis. In order to explain the results, a theoretical framework was used in the final analysis, which proceeds from two perspectives on special education practices according to Bengt Perssons’ (2013) model: the relational and the categorical perspective. The result indicated several factors for well functional support, where the importance of a trusting relation between teacher and student stands out as well as knowledge about special educational support within teachers but also early interventions, such as pedagogical surveys and the use of digital tools. Good relations and collaboration in between special educators, teachers, students and caregivers were other important factors contributing to functional support while the student´s own will and inner urge to succeed; the so called grit was another interesting finding among the perceptions. Factors found working less well for functional support were the opposite; lack of knowledge concerning special educational support within principals, teachers but also within special educators themselves. Noticeable was lack of study guidance in the mother tongue and negligence to insert support to students in special education needs while awaiting results of inquiry. In summary; the most important results from this study concerning factors for functional support were a) knowledge about special educational support within school staff, b) good relations/collaboration between teachers, students, special educators and caregivers, c) early interventions and d) students’ grit and inner will to succeed. The most important result indicating less well functional support was the lack of knowledge about special educational support within staff, which stretches the opposite result, that knowledge about special educational support within principals and teachers is a success factor for functional support. Most perceptions in the result proceeded from a relational perspective on special education practices.

Obtaining a college degree benefits individuals and society, yet only 20% of students are graduating from community colleges. At many institutions, graduation rates have decreased over the last 5 years, including one historically Black community college in the southern United States. To explore possible causes of low graduation rates at this unique and understudied type of college, this correlational study examined the relationships among student engagement, academic performance, and grit-persistence and passion toward long-term goals. Tinto's theory of student persistence served as the theoretical framework for this study. The convenience sample included 116 college students who already had a first-year grade point average (FYGPA). Grit was measured by the Grit-Short Scale; student engagement by the Student Engagement Instrument-College, and academic performance by FYGPA. No statistically significant relationships were found between grit and academic performance, or between student engagement and academic performance, however. Recommendations included additional research with larger samples of students and other HBCUs. Recommendations also included exploring other non-cognitive constructs, such as academic mindsets, learning strategies, socials skills, and academic behaviors to understand those relationships with academic performance. Implications for positive social change include disseminating initial research findings to the college administration for continued research on efforts toward producing more graduates, thereby increasingly providing quality higher education to underserved groups of students.

<p>  </p> <p>Food insecurity describes the lack of access to foods and affects 10.2% of general U.S. households and 27% of low-income households in 2021. Food insecurity is a pervasive public health concern in the United States and has been linked to poor dietary intake and diet quality, overweight and obesity (especially among women), and risk of other chronic diseases, such as diabetes, hypertension and dyslipidemia. </p> <p>To better understand food security status and address its associated health and dietary outcomes among low-income populations, a conceptualized model was built and served as research framework for the dissertation, including 1) internal factors and motivations, such as traits related to self-efficacy and sufficiency that may influence diet and health; 2) external factors of temporary support, such as financial benefits from assistance programs that low-income populations are eligible for that may influence diet and health; and 3) external factors of potentially long-term support, such as nutrition education programs targeting low-income groups that may foster internalized knowledge that could sustain impact and improvement of diet and health in the long-term. Each chapter of this dissertation addresses a component of the model.</p> <p>Cross-sectional analysis of a sample of rural veterans using food pantries quantified psychological traits related to self-motivation and efficacy including grit and help seeking, at the individual and internal factors level of the conceptualized model, and their links to food security and resource use, and revealed an inverse association between grit score and risk of food insecurity. The findings provided evidence for future interventions targeting food insecurity improvement to include education and resources that address traits related to self-efficacy, such as grit, among low-income populations to improve health outcomes directly or through improving food security or use of resources. </p> <p>Using nationally representative data, the second study investigated relationships between food assistance through the Supplemental Nutrition Assistance Program (SNAP) participation, a type of societal level external support, and dietary outcomes among low-income older U.S. adults. There were no differences in dietary quality, usual nutrient intake or risk of inadequacy between SNAP participants and eligible nonparticipants. Furthermore, results revealed a high prevalence of not meeting the Estimated Average Requirement from dietary sources for several nutrients (vitamins A, C, D, E, calcium, and magnesium) but the prevalence was lower when nutrients from dietary supplements were included. The results highlight a need for continued effort to improve nutrient and dietary intake among low-income older adults.</p> <p>External factors of potentially long-term support (e.g. nutrition education and food assistance) were evaluated for relationships with body mass index. A longitudinal sample of low-income women interested in participating in nutrition education through SNAP-Education (SNAP-Ed) was examined to determine the relationship between nutrition education (SNAP-Ed) and food assistance program participation through (SNAP, WIC), separately and in combination, with long-term changes in body mass index. No differences in changes of weight status over time were observed by nutrition education, food assistance, or combination participation. The prevalence of obesity was high among this sample, calling for targeted obesity prevention interventions and further support of healthy lifestyle promotion among low-income populations. </p> <p>The findings shown in this dissertation further reveal a high health burden among low-income groups. The studies filled several research gaps described in the conceptualized model. The results may be used to inform future tailored interventions to address food insecurity, dietary and health outcomes at individual and societal levels, incorporating internal motivation and external support to mediate health and dietary risks among low-income population.</p>
