A Demographic Analysis of Flora Thew Elementary School: An Investigation of Title I Elementary Schools and Minority Student Education
No full textabstract: Flora Thew Elementary School is a Title I elementary school in the Tempe Elementary School District. The student body is predominantly Hispanic with an additional large portion of African American students, all coming from low-income backgrounds. The purpose of this project was to investigate the efficacy of American education in these groups of students as well as a personal analysis of the organization, Arizona Mentor Society, that serves to promote student success. The investigation found that while the American education system already fails these students in many ways, the elementary school itself propagates this failure in a faculty body that is unfamiliar with the culture of their student body. Solutions to this problem would include the diversification of the teacher workforce, more strict but inclusive training of educators, and changes in the assessment of these students
The hydrocyclone for separating light dispersions
No full textVarious new hydrocyclone designs developed by the author for
separating light dispersions from heavier carrying fluids are demonstrated and
their relative efficiencies compared using dispersions of plastic powders in water
and suitable non-dimensional equivalence relations. Detailed measurements of
the flow structure with in these hydrocyclones that have aided design work are also
discussed.
The mixture entering the cylindrical hydrocyclone body
tangentially generates a vortex and due to the centrifugal acceleration in this
vortex the less dense particles migrate towards the axis forming a core. This is
then removed through an axially placed outlet in the upstream end wall of the hydrocyclone
with 5-10% of the total through flow while the remaining particle depleted stream
passes out of the downstream end.
The work investigates the effects upon hydrocyclone
performance of changes in total flow rate, mode of operation, and geometry by
comparing particle concentrations in influent and effluent and the probability
of separation of individual particles, which is calculated from input and
output drop size spectra. From a flow of 60 L/min through an efficient
hydrocyclone of diameter 30 mm with a total head loss of 3.2 bar, it is found
that for particles with a relative differential density of 0.1 in water at 50°C,
99% at 50 µm are separated while 80% are separated at 17 µm and 50% separation
occurs at less than 10 µm.
Measurements of the flow structure within the hydrocyclones
have been made using a Laser Doppler Anemometer and from radial profiles of
axial and tangential velocities particle trajectories have been calculated.
With the application of the hydrocyclone for use with other
mixtures and dispersions in mind, an equivalence relation dependent upon
hydrocyclone Reynolds number is employed by which hydrocyclone performance may
be predicted from standard experimental results. The validity of this
relationship is demonstrated by comparing results from similar geometry
hydrocyclones over a range of sizes with different dispersions and changes in
medium viscosity by using water at various temperatures.</p
An examination of the perceptions of functional capacity evaluations in Prince George, British Columbia: A case study.
No full textFunctional Capacity Evaluations assist with work related decisions when limitations in a worker's functional abilities have been identified. A review of the literature revealed that there are a number of concerns regarding the limitations of the information gathered during a Functional Capacity Evaluation, as well as, the subsequent interpretation and application of the information. This intrinsic case study explored the perceptions of four key stakeholders (evaluee, clinician, employer, and funder) regarding Functional Capacity Evaluations in Prince George, British Columbia. --P.ii.The original print copy of this thesis may be available here: http://wizard.unbc.ca/record=b132601
Experiencing Climate Change and Living Through It—Provocations for Education Based on South African Youth Experiences of Climate Change Policymaking and Politics
No full textThis research investigates youth participation in climate change politics and policymaking in South Africa, responding to a notable lack of Global South-facing studies in the literature on youth climate activism. Guided by our lead author’s substantial engagement in South Africa’s youth climate movement from 2014–2024 and drawing upon semi-structured interviews with 12 young climate activists, we offer rich insights into young South Africans’ motivations to participate in climate politics and policymaking. We then draw upon these insights to offer a series of provocations for climate change education. On investigating why youth participate, we find that although they report similar intrinsic and extrinsic motivations for participation to their Global North counterparts, South African youth climate activists place far greater emphasis on situated awareness and lived experience. We further improve the understanding of how young people perceive meaningful participation and climate (in)justices and how this shapes and is shaped by their activism. We therefore emphasise the value of incorporating both local case studies and affective elements in climate change pedagogies to encourage participation in collective climate action. Ultimately, we call for an enhanced recognition and inclusion of youth as active contributors to, and educators within, climate change governance and for the reconceptualization of youth climate activism, and policy engagement as key sites of transformative learning

Driving and Elderly Primes in a Simulated Driving Environment
No full textabstract: ABSTRACT Research studies have demonstrated that stereotypes can elicit a priming response. An experiment was conducted to test the effects of priming elderly and young stereotypes on driving behavior. Participants drove in a driving simulator while navigating through two driving routes. Participants were guided by a neutral voice similar to "Siri" that informed them where to turn. Each route primed the participants with names that were deemed "old" or "young" as determined by a survey. The experiment yielded slower driving speeds in the elderly condition than in the young consistent with previous research regarding elderly stereotypes (Bargh et al, 1996; Branaghan and Gray, 2010; Taylor, 2010; Foster, 2012). These findings extend research on priming and behaviors elicited by participants in a simulated driving environment.Dissertation/ThesisM.S. Applied Psychology 201

First use of intracoronary beta‐radiation to prevent recurrent in‐stent restenosis in a transplanted heart
No full textEcuaciones en Diferencias Finitas Parciales en Mallas Eléctricas
No full textThis paper presents a method to analyze a triangular network of equal electrical impedances, and composed by triangular meshes constituted themselves by these impedances; and shows how to obtain a partial, finite differences equation, relating the Maxwell current in each mesh (n,m) with those currents in the currents in the neighboring meshes. The differences equation is solved by the method of Lagrange, and boundary conditions are applied in order to obtain explicitly the total, equivalent impedance of the network and the distribution of the Maxwell currents across thew hole network. This treatment surpasses the usual one of isolating meshes and nodes, applying the two laws of Kirchhoff tocurrents and voltages and finally solving a large system of linear algebraic equations by numerical or algebraic methods. During many years as an electrical engineer, the author has not seen used this methodology, so that he considers this is an original and useful addition to the theory of electric circuits
