The Colorado Trust’s Healthy Communities Initiative: Results and Lessons for Comprehensive Community Initiatives
No full text· This article summarizes how 29 diverse communities throughout Colorado implemented the Colorado Healthy Communities Initiative (CHCI), which was conceived and funded by The Colorado Trust to engage community residents in the development of locally relevant strategies to improve community health.
· In line with the World Health Organization’s Healthy Cities model, CHCI emphasized (a) inclusive, representative planning; (b) a broad definition of “health”; (c) consensus decision making; and (d) capacity building among local stakeholder groups.
· Communities implemented an array of projects (on average, six per community) that extended well beyond traditional health promotion and disease prevention. The most common action projects focused on community problem solving, civic engagement, and youth development. Many of the grantees established projects or new institutions that had a long-term community impact.
· Key success factors for CHCI included (a) a wellspecified planning model, (b) a planning process facilitated by expert consultants, (c) a unifying “healthy community” vision developed at the beginning of the process by diverse stakeholders, (d) a willingness by stakeholders to work collaboratively to define “key performance areas” and then to implement “action projects” to achieve them, and (e) an appropriate level of funding for implementation ($50,000 per site per year).
· The outcomes and impacts of CHCI might have been improved by better anticipating the requirements for sustaining the energy and work initiated during the planning process.
· At the end of the initiative, CHCI provided the funders with a broader, deeper understanding of the requirements, opportunities, and realities associated with promoting “community health.

Allan Findlay’s work was supported by an Economic and Social Research Council grant [ES/K007394/1].While researchers are increasingly re-conceptualizing international migration, far less attention has been devoted to re-thinking short-distance residential mobility and immobility. In this paper we harness the life course approach to propose a new conceptual framework for residential mobility research. We contend that residential mobility and immobility should be re-conceptualized as relational practices that link lives through time and space while connecting people to structural conditions. Re-thinking and re-assessing residential mobility by exploiting new developments in longitudinal analysis will allow geographers to understand, critique and address pressing societal challenges.Peer reviewe

Contact fatigue : life prediction and palliatives
No full textThesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Materials Science and Engineering, 2002.Includes bibliographical references (p. 125-135).This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Fretting fatigue is defined as damage resulting from small magnitude (0.5-50 microns) displacement between contacting bodies where at least one of the bodies has an applied bulk stress. The applicability and limits of a fracture mechanics based life prediction is explored. Comparisons are made against highly controlled experiments and less controlled but more realistic experiments using a novel dovetail attachment fixture. Surface engineering approaches are examined from a mechanics perspective. Using a new tool, depth sensing indentation, the mechanical properties of an aluminum bronze coating are determined. Fretting fatigue experiments are performed on specimens coated with aluminum bronze and on specimens treated with low plasticity burnishing. Low plasticity burnishing is a new method of introducing beneficial compressive residual stresses without significant cold work at the surface. A mechanics based approach to the selection of palliatives is addressed.by Brett P. Conner.Ph.D
Marijuana use impacted by legalization and individual factors
No full text2016 Summer.Includes bibliographical references.In 2014, marijuana became legal for recreational use for adults 21 and older in Colorado (Colorado Const. art XVIII § 16., 2012). There are potential health risks related to marijuana dependence, which are more prominent in adolescent users (Volkow, Baler, Compton, & Weiss, 2014). Medical marijuana legalization has not been shown to increase marijuana use or prevalence of dependence (Cerdá, Wall, Keyes, Galea, & Hasin, 2012). Changes related to legalization may include increased availability and social acceptance, as well as decreased price and perceived harm of use (Hopfer, 2014). There also may be increased interest in moving to Colorado related to the changes in marijuana laws (United States Census Bureau, 2015; Institutional Research & Analysis, 2014). The facets of sensation seeking, risk seeking and experience seeking, influence marijuana use (Zuckerman, 2007; Conner & Henson, 2011). Sexual orientation has a quadratic relation to marijuana use (Ford & Jasinski, 2006). Use among bisexuals is higher than use at either end of the spectrum (Eisenberg & Wechsler, 2003). Based on these findings, several hypotheses were made. First, marijuana use would increase in college students after legalization, however just for those 21 and older. Next, risk seeking and experience seeking would both uniquely moderate marijuana use before and after legalization and in underage and of-age students. Third, sexual orientation would have a quadratic relation with marijuana use. Finally, the relation between the influence of marijuana leglislation on non-residents decisions to attend a Colorado college and marijuana use was examined. Data was collected from undergraduate students (N = 5241) at a Colorado university. Participants were assessed for marijuana use behavior, sensation seeking, sexual orientation, and influence of marijuana laws on non-resident decision to attend Colorado schools. Pearson’s Chi-square, analysis of variance, negative binomial regressions, and polyserial correlations were used to test the hypotheses. Results indicated that marijuana use has increased since legalization for all students, but moreso for those over 21 (p < .001). No differences in frequency of past month use was found between pre and post legalization (p = .615). Regression analysis found experience seeking to be a significant predictor of past 30 day use (p <.05). Additionally, risk seeking predicted use for those under 21 (p <.01). A quadratic relation was found between sexual orientation and past month use, where use increased at a decreasing rate from the homosexual end of the spectrum to the heterosexual end (p <.01). Correlations were found between degree of marijuana law influence and both past 30 and lifetime use among non-resident college students (ρ = 0.29, p < .001; ρ = 0.17, p < .001). Overall, legalization, experience seeking, underage risk seeking, sexual orientation, and legislation influence on decision making all predicted marijuana use. These findings may help inform other states considering legalization of potential outcomes and groups at higher risk of marijuana use. Future research should examine longer term effects of legalization, as well as effective interventions

Internal Atomic-Scale Structure Determination and Band Alignment of II-VI Quantum Dot Heterostructures
No full textThis
work shows that ZnTe/CdSe core/shell quantum dots synthesized by standard
literature procedures in actuality have an alloyed CdxZn1-xTe
core. We employ X-ray absorption spectroscopy (XAS) at all four K-shell
ionization edges (Zn, Te, Cd, Se) and perform a global fitting analysis in
order to extract the first-shell bond distances. We combine our XAS results
with transmission electron microscopy (TEM) sizing and elemental analyses,
which allows us to propose models of the internal particle structure. Our
multimodal characterization approach confirms (1) the presence of Cd-Te bonds, (2) cation alloying in the particle core (and the
absence of anion alloying), and (3) a
patchy pure-phase CdSe shell. We synthesize particles of different shell
thicknesses and performed synthetic control studies that allowed us to discard a
ZnTe/CdTe/CdSe core/shell/shell structure and confirm the alloyed core/shell
structure. Our structural analysis is
extended with electronic band structure calculations and UV/vis absorption spectroscopy,
demonstrating that the alloyed CdxZn1-xTe/CdSe
core/shell quantum dots exhibit a direct band gap, different from the predicted
type-II band alignment of the intended ZnTe/CdSe core/shell quantum dots. This study highlights the challenges with
synthesizing II-VI quantum dot heterostructures and the power of XAS for
understanding the internal structure of heterogenous nanoparticles.</p
Performance Aspects of the New Orleans Jazz Style: A Guide for Jazz Musicians
No full textNew Orleans jazz is America’s first original art form. It is a shining example of what can be achieved in a multicultural environment. Since the first jazz album was released in 1917, jazz has steadily evolved and changed into an array of substyles. In the process, New Orleans jazz has become more and more distant and less understood. This essay seeks to counter that trend by analyzing and explaining the main performance aspects of the New Orleans jazz style. The analysis section of this essay will be divided into three chapters. Chapter 1 will focus on improvisation. Chapters 2 and 3 will focus on the roles of the instruments of the standard New Orleans jazz ensemble. In order to gain insight into the characteristics of the style, eight solos by prominent New Orleans jazz musicians will be transcribed and analyzed. In addition, scholarly articles, books, music scores, and videos will be referenced. Music examples will also be composed by the author. The goal is to provide a guide for jazz musicians seeking to better understand the New Orleans jazz style.</p

Current Views on Teacher Word Choice in American College Flute Lessons
No full textThe purpose of this study is to explore the factors that influence a teacher’s word choice in American private college-level flute lessons. Most of the research that has been conducted on music instruction focuses on technical methods for the purpose of enhancing curricula. Some research exists which explores the more psychological side of teaching and learning; however, the research that studies the private music lesson often seeks to understand either the teacher-student relationship through the eyes of students, or to understand music teacher perceptions on the ways in which their teaching informs their performing. While many studies and publications indirectly speak to the use of language in teaching and learning music, most research that explores the effectiveness of teaching approaches for specific techniques does not explore the verbal delivery used in the method. There is little literature in print which addresses teacher word choice, and even less, still, in the flute world. An examination of the available literature on subjects relevant to the factors that influence teacher word choice revealed six major topics: artist-teacher background, teacher’s responsibility to meet student’s needs and expectations, significance of the one-to-one teacher-student relationship, verbal teacher feedback, heightened sensitivities in music instruction, and words and music learning. Careful review of the prose relating word choice and existing practices in music instruction today led the author to pose the following research questions: 1. What elements of a teacher’s background influence their word choice in lessons? 2. To what degree does student individuality affect a teacher’s word choice from student to student? 3. How do teachers reflect their goals and values in their word choice? The research questions were addressed first by conducting semi-structured interviews with five of the nation’s leading flute pedagogues, chosen based on both the longevity and prestige of their performing career and the notable successes of current and former students. In alphabetical order, the subjects were: Leone Buyse, Marianne Gedigian, Amy Porter, Jim Walker, and Carol Wincenc. The interview questions were designed to uncover perceptions about the artist-teachers’ language use and how it relates to the six overarching topics discovered in the literature review. Upon completing and transcribing the interviews, the author “encoded” each transcription to discover common themes regarding the influences on the type of language used in lessons. The author performed every stage of research involved in this study, including the interview design, execution, and analyses. The study would be of use to any flutist, music teacher, or flute teacher who wishes to expand their knowledge of the complexity of music learning, increase their understanding of the intricacies of the one-to-one instruction model and explore the potentials for interconnectedness and musical creativity that result from thoughtful word choice.</p
