Case Studies Of Nature-Based Preschool Models In The Midwest

The main motivation behind this capstone research project was to more fully understand the four major program models of nature-based preschools. This qualitative, multiple case study sought to uncover the benefits and challenges of these models and apply these benefits and challenges to opening a diverse, nature-based preschool in South Bend, Indiana. Data collection included interviews and site visits to four nature-based preschool program models in the Midwest and two interviews with local early childhood experts. The study concluded each nature-based preschool program model had both benefits and challenges unique to that model. Two additional differences were found as well. Furthermore, it was determined that evidence of barriers for low-income families in attending nature-based preschools exists across all models. These conclusions are relevant for anyone seeking to develop a new nature-based program. In relation to South Bend, Indiana the study found that new high-quality preschool programs are needed and two promising models were identified for opening a new diverse, nature-based preschool

Post-Concussion Symptom Score as a Possible Predictor of Protracted Recovery in High School Athletes

As concussion research shifts from diagnostic to managing return to play (RTF), many studies have sought to establish safe guidelines for recovery. Computer-based neuropsychological programs measure cognitive function performance typically affected by brain injury and include a self-report post-concussion symptoms scale. The use of the total score of a post-concussion symptoms scale as a possible predictor of protracted recovery in high school athletes following injury is still being researched. This study used stored data obtained from the Vanderbilt Sports Concussion Center involving concussed high school athletes with a post-concussion symptom score and subsequent documentation of recovery time. A one-way ANOVA compared the dependent variable of total initial symptom score to age, gender, days between, symptom change, and previous concussion history. A pot hoc regression analysis was used to determine if there was a relationship between the dependent initial post-concussion symptom score and independent variables above. Data analysis from this study presented evidence that a higher symptom load at injury correlated to a protracted recovery. Further results showed individuals with previous concussion history reported more symptoms at the onset of injury and had a protracted recovery from a concussion than those individuals with no previous history of concussion. There was also a significant effect of gender on symptom reporting

What can be shown, cannot be said: Wittgenstein's conception of philosophy in the Tractatus and the Investigations

My thesis is that the say-show distinction is the basis of Ludwig Wittgenstein’s conception of philosophy in both the Tractatus Logico-Philosophicus (1921) and the Philosophical Investigations (1953).Wittgenstein said that the Investigations should be read in conjunction with the Tractatus. To understand the Tractatus we must understand the say-show distinction: the principle that "what can be shown, cannot be said". A correct interpretation of Wittgenstein's philosophy will explain the significance of the say-show distinction for the Investigations. I evaluate three available readings of the say-show distinction which fail to meet this challenge. I argue that Wittgenstein's main purpose throughout his career was to replace traditional philosophy with an alternative conception of philosophy, which can only be understood through the say-show distinction. The Tractatus and the Investigations are different attempts to present the same conception of philosophy. I describe how, in both cases, they present a distinctive account of the nature of philosophical problems, the appropriate methods of philosophy, the end result of a philosophical task and the overall aim of philosophy. I argue that my interpretation provides a correct view of the significant continuities and discontinuities between the Tractatus and the Investigations. The failure of the Tractatus was not a flaw in the conception of philosophy presented in it, nor a flaw in the say-show distinction, hi the Tractatus, Wittgenstein failed properly to implement his proposed conception of philosophy, as he remained in the grip of traditional philosophical presuppositions. The Investigations presents the same conception of philosophy, but freed from the presuppositions of the Tractatus. The say-show distinction remains the basis of Wittgenstein’s conception of philosophy in the Investigations

The Relationship Between Selective Serotonin Reuptake Inhibitors and Romantic Relationship Quality

This investigation examined the relationship between selective serotonin reuptake inhibitors (SSRIs) use and romantic relationship quality. The research sample consisted of participants in the attachment phase of their romantic relationship who had been in the same, current romantic relationship for a minimum of two years. Participants were recruited via professional listservs, electronic social networking, and prior relationships with the principal investigator. A total of 165 individuals participated in the main analysis. Results revealed no significant differences on romantic relationship quality scores by SSRI use after controlling for interest in sexual activity, sexual relationship satisfaction, depression, anxiety, paranoid, dependent, schizoid, sexual activity per month, time spent with one?s partner, and dates per month. Correlational analysis revealed a significant positive relationship between SSRI use and interest in sexual activity, depressive symptoms, and dependent, paranoid, and passive-aggressive personality patterns. Results from independent T-tests found higher means on each of these variables with those using a SSRI. Higher scores on the scales that measured depressive symptoms and the personality patterns indicate the presence of more symptoms. However, higher scores on the interest in sexual activity variable indicate less interest in sexual activity. Correlational analysis revealed a significant negative relationship between partner?s antidepressant status and the overall score on the Dyadic Adjustment Scale, dyadic satisfaction, dyadic cohesion, sexual activity per month, and sexual relationship satisfaction. Results from a MANOVA analysis revealed differences in mean scores on sexual relationship satisfaction by partner?s antidepressant status. No significant differences in mean scores were found between scores on the dyadic consensus, dyadic adjustment, and dyadic satisfaction by partner?s antidepressant status

Seal Joint Analysis and Design for the Ares-I Upper Stage LOX Tank

The sealing capability of the Ares-I Upper Stage liquid oxygen tank-to-sump joint is assessed by analyzing the deflections of the joint components. Analyses are performed using three-dimensional symmetric wedge finite element models and the ABAQUS commercial finite element software. For the pressure loads and feedline interface loads, the analyses employ a mixed factor of safety approach to comply with the Constellation Program factor of safety requirements. Naflex pressure-assisted seals are considered first because they have been used successfully in similar seal joints in the Space Shuttle External Tank. For the baseline sump seal joint configuration with a Naflex seal, the predicted joint opening greatly exceeds the seal design specification. Three redesign options of the joint that maintain the use of a Naflex seal are studied. The joint openings for the redesigned seal joints show improvement over the baseline configuration; however, these joint openings still exceed the seal design specification. RACO pressure-assisted seals are considered next because they are known to also be used on the Space Shuttle External Tank, and the joint opening allowable is much larger than the specification for the Naflex seals. The finite element models for the RACO seal analyses are created by modifying the models that were used for the Naflex seal analyses. The analyses show that the RACO seal may provide sufficient sealing capability for the sump seal joint. The results provide reasonable data to recommend the design change and plan a testing program to determine the capability of RACO seals in the Ares-I Upper Stage liquid oxygen tank sump seal joint
