An Examination of Intragroup Process in Service-Learning Teams
Small group work performed in the context of university service-learning projects has been seen as a vehicle well-suited to teaching students about group dynamics and how to work on real world problems as members of a team. Little research, however, has focused on the intragroup processes involved in service-learning. The present study was conducted in the context of a service-learning project in which twenty groups of four to five university business school students taught continuation high school students a series of lessons regarding life skills such as goal setting and career readiness. The lesson planning sessions of the university students were video recorded and the videos were then analyzed for patterns of utterances by group participants (questions; instructions; suggestions; etc.) that occurred during the sessions. An iterative process of coding and recoding was employed to capture each behavior for further study. The results suggest that the groups engaged in a surprising level of meaningful collaboration, with leadership shared among group members, and little evidence of individual dominance of groups, or conflict between students

Optimización de recursos en el diseño y construcción de pistas y veredas, aplicando la metodología de losas cortas en la ciudad de Puno
En la ciudad de Puno, muchas vías sin pavimentar, generan malestar no solamente en los que cuentan con vehículo para su transporte, sino a la población por la contaminación debido a la acumulación de lodos y emisión de partículas suspendidas, la presente tesis tiene como objetivo optimizar los recursos (mano de obra, materiales, equipos y herramientas) en el diseño y construcción de pistas y veredas, aplicando la metodología TCP en la ciudad de Puno, Jr. Valdizan vía con mayor área de intervención del proyecto “Mejoramiento de la transitabilidad vehicular y peatonal en los jirones y pasajes del sector noreste de la ciudad de Puno”. Teniendo como resultados, de acuerdo a la metodología TCP en relación a metodologías convencionales (AASHTO93 - PCA84), la optimización de recursos es de mano de obra 15.27 %, materiales 22.04 %, equipos 2.16%. Igualmente, las tensiones generadas en SAP2000, mediante la metodología TCP obtiene un espesor optimizado respecto a metodologías convencionales, según el tipo de tránsito. Los costos unitarios por metro cuadrado de estructura de pavimento mediante metodologías convencionales es S/. 108.06; y en metodología TCP de S/.91.25. Finalmente se evaluaron las propiedades físico-mecánicas de subbase y subrasante, detallando que en diseños convencionales es sumamente importante el valor de CBR al 95% de la subrasante como variable fundamental; y el CBR al 100% de la subbase es una variable incidente en la metodología TCP. Se utilizó metodología tipo aplicada porque busca modificar una realidad problemática, nivel descriptivo ya que especifica propiedades y características del análisis.Tesi
Constant Site Hemodialysis in the Pediatric Population: Successful use of VWINGs in Three Patients
Introduction: Reliable vascular access for hemodialysis is challenging in the pediatric population. The Venous Window Needle Guide (VWING; Vital Access Corp, Salt Lake City, Utah) is an implanted surgical device that allows for constant site access but has not been reported in pediatric patients.
Case description: Three patients under 18 years of had a brachiobasilic fistula created with a minimum of 6 weeks for fistula maturation prior to VWING placement. This paper describes the management of constant site dialysis using VWING as well as strategies used for successful long-term management. Patients include a 15-year-old male with end-stage renal disease (ESDR) secondary to hemolytic uremic syndrome (HUS), a 14-year-old female with ESRD secondary to systemic lupus, and a 17-year-old female with ESRD secondary to rapidly progressive glomerulonephritis. All three patients had successful placement of VWING allowing for improved AVF access for dialysis for several years.
Conclusion: In our limited experience with VWINGs in the pediatric population, we have demonstrated a successful method of long-term constant-site dialysis using VWING as an adequate alternative to other interventions for difficult-to-access arteriovenous fistulas (AVFs)

Tubular space truss structure for SKITTER 2 robot
The Skitter 2 is a three legged transport vehicle designed to demonstrate the principle of a tripod walker in a multitude of environments. The tubular truss model of Skitter 2 is a proof of principal design. The model will replicate the operational capabilities of Skitter 2 including its ability to self-right itself. The project's focus was on the use of light weight tubular members in the final structural design. A strong design for the body was required as it will undergo the most intense loading. Triangular geometry was used extensively in the body, providing the required structural integrity and eliminating the need for cumbersome shear panels. Both the basic femur and tibia designs also relied on the strong geometry of the triangle. An intense literature search aided in the development of the most suitable weld techniques, joints, linkages, and materials required for a durable design. The hinge design features the use of spherical rod end bearings. In order to obtain a greater range of mobility in the tibia, a four-bar linkage was designed which attaches both to the femur and the tibia. All component designs, specifically the body, femur, and the tibia were optimized using the software package IDEAS 3.8A Supertab. The package provided essential deformation and stress analysis information on each component's design. The final structure incurred only a 0.0544 inch deflection in a maximum (worst case) loading situation. The highest stress experienced by any AL6061-T6 tubular member was 1920 psi. The structural integrity of the final design facilitated the use of Aluminum 6061-T6 tubing. The tubular truss structure of Skitter 2 is an effective and highly durable design. All facets of the design are structurally sound and cost effective
Psychometric Properties of the Hoarding Rating Scale-Interview
The present study tested the psychometric properties of an expanded version of the Hoarding Rating Scale (HRS-I), a semistructured interview for hoarding disorder (HD). Eighty-seven adults with HD and 44 healthy control (HC) participants were assessed using the HRS-I and completed a battery of self-report measures of HD severity, negative affect, and functional impairment. All interviews were audio recorded. From the HD participants, 21 were randomly selected for inter-rater reliability (IRR) analysis and 11 for test-retest reliability (TRR) analysis. The HRS-I showed excellent internal consistency (α = 0.87). IRR and TRR in the HD sample were good (intra-class coefficients = 0.81 and 0.85, respectively). HRS-I scores correlated strongly with scores on the self-report Saving Inventory-Revised (SI-R); partial correlations indicated that the HRS-I clutter, difficulty discarding, and acquiring items correlated significantly and at least moderately with corresponding SI-R subscales, when controlling for the other SI-R subscales. The HD group scored significantly higher on all items than did the HC group, with large effect sizes (d = 1.28–6.58). ROC analysis showed excellent sensitivity (1.00) and specificity (1.00) for distinguishing the HD and HC groups with a cutoff score of 11. Results and limitations are discussed in light of prior research
Tunable Blood Shunt for Neonates With Complex Congenital Heart Defects
Despite advancements in procedures and patient care, mortality rates for neonatal recipients of the Norwood procedure, a palliation for single ventricle congenital malformations, remain high due to the use of a fixed-diameter blood shunt. In this study, a new geometrically tunable blood shunt was investigated to address limitations of the current treatment paradigm (e.g., Modified Blalock-Taussig Shunt) by allowing for controlled modulation of blood flow through the shunt to accommodate physiological changes due to the patient’s growth. First, mathematical and computational cardiovascular models were established to investigate the hemodynamic requirements of growing neonatal patients with shunts and to inform design criteria for shunt diameter changes. Then, two stages of prototyping were performed to design, build and test responsive hydrogel systems that facilitate tuning of the shunt diameter by adjusting the hydrogel’s degree of crosslinking. We examined two mechanisms to drive crosslinking: infusion of chemical crosslinking agents and near-UV photoinitiation. The growth model showed that 15–18% increases in shunt diameter were required to accommodate growing patients’ increasing blood flow; similarly, the computational models demonstrated that blood flow magnitudes were in agreement with previous reports. These target levels of diameter increases were achieved experimentally with model hydrogel systems. We also verified that the photocrosslinkable hydrogel, composed of methacrylated dextran, was contact-nonhemolytic. These results demonstrate proof-of-concept feasibility and reflect the first steps in the development of this novel blood shunt. A tunable shunt design offers a new methodology to rebalance blood flow in this vulnerable patient population during growth and development
