Recovered Voices: Fairy Tales and the Reading Child
In the traditional literature classroom, students are typically guided through literature discussions by their teacher, and then assessed on how well they can reiterate predetermined interpretations of what they have read. Within these literature discussions, classroom talk creates a power structure, with the teacher as owner of knowledge, and students as those lacking this knowledge. This study seeks to upset this power structure, by removing the guiding force of the teacher in literature discussions, as well as the assessments which follow. In a further effort to allow for a literature discussion which is genuinely for students, the genre of fairy tales will serve as the selected literature. The field of curriculum studies is concerned with recognizing contexts, and working to understand how these many contexts contribute to the education of children. Located within the field of literary criticism, interpretive communities have been selected as a methodology which recognizes a way of looking at students looking at literature through unique perspectives. By allowing students the opportunity to experience literature without the attached traditional activities imposed on them, it is the intent that a novel discourse will be created; one that recognizes and values the interpretation of the child
Childhood Obesity: Prevention & Intervention
Childhood obesity rates have skyrocketed in the recent years. These trends are alarming since childhood obesity has been linked to numerous health conditions, socioemotional consequences, and academic consequences. This project examines the factors that have been associated with childhood obesity and the consequences of being obese or overweight for children. This project also presents lifestyle changes that parents can make to reduce the likelihood of their children becoming overweight or obese

Ab-initio-MO-Studie Methyl- und Phenyl-substituierter Allenyl-Kationen
An den Methyl- und Phenyl-substituierten Allenyl-Kationen 3 - 12 (Tab. 1) wurden ab-initio-MO-Berechnungen unter Verwendung des STO-3G Basissatzes durchgeführt. Die berechneten Bindungslängen und Ladungsverteilungen zeigen Delokalisierung der positiven Ladung an, wie in Formel 1 gezeigt. Mit Hilfe isodesmischer Reaktionen werden Stabilisierungsenergien von Substituenten in 1- und 3-Position ermittelt. Diese Werte ermöglichen in Kombination mit der experimentell bekannten Bildungswärme des Stammkörpers 2 die Bestimmung von H sämtlicher Allenyl-Kationen 3 - 12. Der Vergleich dieser Daten mit einigen experimentell bestimmten Bildungswärmen zeigt Übereinstimmung innerhalb von 2 kcal/mol. Es werden Voraussagen für das Reaktionsverhalten gegenüber n-Nucleophilen und -Systemen gemacht
PACE Technical Report Series, Volume 5: Mission Formulation Studies
This chapter summarizes the mission architecture for the Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission, ranging from its scientific rationale to the history of its realized conception to itspresent-day organization and management. This volume in the PACE Technical Report series focuses ontrade studies that informed the formulation of the mission in its pre-Phase A (2014-2016; pre-formulation:define a viable and affordable concept) and Phase A (2016-2017; concept and technology development).With that in mind, this chapter serves to introduce the mission by providing: a brief summary of thescience drivers for the mission; a history of the direction of the mission to NASA's Goddard Space Flight Center (GSFC); a synopsis of the mission's and instruments' management and development structures; and a brief description of the primary components and elements that form the foundation ofthe mission, encompassing the major mission segments (space, ground, and science data processing) and their roles in integration, testing, and operations
Fenomeno erosivo in corrispondenza di pile di ponte allocate in prossimità delle sponde.
La tesi presenta un analisi sperimentale riguardo gli effetti della posizione delle pile dei ponti lungo la sezione fluviale sia in presenza di materiale flottante (debris) che in sua assenza e la ricerca dell'equazione che descriva l'evoluzione temporale dello scavo.
La tesi è articolata in cinque capitoli:
-nel primo capitolo viene descritto lo stato attuale delle conoscenze riguardo l'erosione localizzata presso le pile dei ponti sia in presenza che in assenza di materiale flottante;
-il secondo capitolo descrive l'apparato sperimentale e le modalità d'esecuzione delle prove;
-il terzo capitolo tratta l'elaborazione dei dati, la ricerca delle equazioni e la verifica delle stesse;
-il quarto capitolo confronta, in maniera qualitativa, la morfologia del fondo al termine deli vari test;
-il quinto capitolo chiude il lavoro e riassume le conclusioni
Measuring changes in Schlemm’s canal and trabecular meshwork in different accommodation states in myopia children: an observational study
Abstract
Purpose: Studies were designed to evaluate changes in the size of the Schlemm's Canal (SC) and trabecular meshwork(TM) during accommodation stimuli and cycloplegia states in myopic children.
Methods: 34 children were enrolled. A -6D accommodation stimulus was achieved by looking at an optotype through a mirror. Cycloplegia state was induced with 1% tropicamide. Two states were confirmed by measuring the central lens thickness(CLT), the anterior chamber depth and the pupil diameter. The size of the Schlemm's Canal (SC) and Trabecular Meshwork(TM) was measured using swept-source optical coherence tomography. And the associations between the change of the SC and the CLT were analyzed.
Results: When compared with the relaxation state, under -6D accommodation stimuli, the size of SC increased significantly: the SC area (SCA) amplified from 6371±2517μm2 to 7824±2727 μm2; the SC length (SCL) from 249±10 μm to 295±12 μm, and SC width (SCW) from 27±9 μm to 31±8 μm. Under cycloplegia state, the SCA reduced to 5009±2028 μm2; the SCL to 212±μm and the SCW to 22±5 μm. In addition, the changed areas of SCA (r=0. 35; P=0.0007), SCL (r=0. 251; P=0.0172), and SCW (r=0. 253; P=0.016) were significantly correlated with the change in CLT. However, the size of TM did not change substantially when compared with the relaxation state. Only the TM length (TML) increased from 562±45μm to 587±47μm after -6D accommodation stimulus.
Conclusion: SC size enlarges after -6D accommodation stimuli and shrinks under cycloplegia. However, for TM, only the TM length increase under accommodation stimulus state.

An appraisal of rehabilitation regimes used for improving functional outcome after total hip replacement surgery
This study aimed to systematically review the literature with regards to studies of rehabilitation programmes that have tried to improve function after total hip replacement (THR) surgery. 15 randomised controlled trials were identified of which 11 were centre-based, 2 were home based and 2 were trials comparing home and centre based interventions. The use of a progressive resistance training (PRT) programme led to significant improvement in muscle strength and function if the intervention was carried out early (< 1 month following surgery) in a centre (6/11 centre-based studies used PRT), or late (> 1 month following surgery) in a home based setting (2/2 home based studies used PRT). In direct comparison, there was no difference in functional measures between home and centre based programmes (2 studies), with PRT not included in the regimes prescribed. A limitation of the majority of these intervention studies was the short period of follow up. Centre based program delivery is expensive as high costs are associated with supervision, facility provision, and transport of patients. Early interventions are important to counteract the deficit in muscle strength in the affected limb, as well as persistent atrophy that exists around the affected hip at 2 years post-operatively. Studies of early home-based regimes featuring PRT with long term follow up are needed to address the problems currently associated with rehabilitation following THR
