The In-Sync City Historic Communities in a Changing World
The city of Honolulu recently adopted plans for a massâtransit system to service West âOahu because of escalating traffic problems, amongst other issues. The system will transport residents to and from the downtown business district. In doing so, surrounding communities are already being affected by multiple urban design options that are currently being explored to encourage growth along the transit route. In particular, the future downtown Chinatown transit station has potential to not only generate social and economic growth for the area but also to revitalize the community and protect the unique culture through the use of community participation techniques and TransitâOriented Development (TOD) principles. Based on a series of case studies, historicalâinterpretive research, firstâhand interviews, and mapping exercises this doctorate project discusses common trends based on the similarities and differences between the requirements of TODs and that of historic communities. The principles for TODs stress that station designs should be compact and should consist of multiple uses, all of which could transform the area into a destination for residents, visitors, and investors.1 Overall, the guidelines are written to apply to any community. In doing so, TODs tend to have a reputation for forcing a oneâsizeâfitsâall solution on how to successfully develop communities located along transit lines, which lends itself to controversy since communitiesâhistoric communities especiallyâdiffer drastically. Through the use of logical argumentation, a series of hypotheses is provided for how historic communities can respond positively to the implementation of not only massâtransit systems, but any modern stimulus. The overall objective is to provide a potential solution or guide for future developers, city officials, urban planners, architects, and community stakeholders of historic communities to follow when facing similar situations. Through testing the hypotheses on Honoluluâs Chinatown, a simplified, graphicâbased process is suggested. The process sets out to define how other historic communities can evaluate themselves and utilize a modern stimulus as a means to grow and evolve sustainably over time without compromising the unique culture of the area. 1 Robert T.

Protective Factors Among Postsecondary Students Enrolled in a First-Generation Program
For generations, researchers have examined attributes that contribute to the adaptability of low socioeconomic youth. Attributes that help one become resilient are known as protective factors. The purpose of this descriptive study was to explore the protective factor(s) that contributed to the enrollment of first-generation, low-socioeconomic status (SES) students at a southern land-grant university. The population consisted of postsecondary students in a First Scholars program during the 2015-2016 academic year. The authors examine the existing literature on the effects of low SES on postsecondary education in order to explore what assists these students in maintaining a steadfast behavior. Recommendations are made for the recruitment of students who display a higher resiliency to be successful at the postsecondary level and for the First Scholars program on how to further enhance the program
AGAINST THE ODDS: A STUDY OF LOW SOCIOECONOMIC STATUS STUDENTSâ ENROLLMENT IN HIGHER EDUCATION
For generations, researchers have been examining attributes that make low socioeconomic status students resilient. Attributes that help one become resilient are known as protective factors. The purpose of this study was to describe the protective factor(s) that contributed to the first-generation, low socioeconomic status studentsâ enrollment at The University of Kentucky. The population for this study consists of the University of Kentucky First Scholars participants during the 2015 â 2016 academic year. The researcher examines the existing literature on low socioeconomic status effects on post-secondary education. Recommendations were made for the University of Kentuckyâs First Scholars Program on how to further enhance their program and continue promoting low socioeconomic status students with opportunities in higher education

Ultra faint dwarfs: probing early cosmic star formation
We investigate the nature of the newly discovered Ultra Faint dwarf
spheroidal galaxies (UF dSphs) in a general cosmological context simultaneously
accounting for various ``classical`` dSphs and Milky Way properties including
their Metallicity Distribution Function (MDF). To this aim we extend the merger
tree approach previously developed to include the presence of star-forming
minihaloes, and an heuristic prescription for radiative feedback. The model
successfully reproduces both the observed [Fe/H]-Luminosity relation and the
mean MDF of UFs. In this picture UFs are the oldest, most dark matter-dominated
(M/L > 100) dSphs with a total mass M= 10^{7-8}Msun; they are leftovers of
H_2-cooling minihaloes formed at z > 8.5, i.e. before reionization. Their MDF
is broader (because of a more prolonged SF) and shifted towards lower [Fe/H]
(as a result of a lower gas metallicity at the time of formation) than that of
classical dSphs. These systems are very ineffectively star-forming, turning
into stars by z=0 only <3% of the potentially available baryons. We provide a
useful fit for the star formation efficiency of dSphs.Comment: 5 pages, 4 figures, accepted for publication in MNRAS

Understanding Assistive Programs: Evaluating the Impact of Various Math Services on Student Performance
High school math performance has the potential to have a positive impact on later educational success. This project seeks to determine the role of math services and intervention programs including online and in-person tutoring, workshops, coaching, physical tools, and other class services on studentsâ performance in the North Carolinaâs High School Math 1 course. Data being used was gathered from rural North Carolina middle and high schools by the college access program GEAR UP (Gaining Early Awareness and Readiness for Undergraduate Programs). The effects of these services will be measured by End of Grade (EOG) test and course grades in the Math 1 course. This project will help develop a deeper understanding of how these types of intervention services impact students\u27 performance in current and future math courses
First stars in Damped Lyman Alpha systems
In order to characterize Damped Lyman Alpha systems (DLAs) potentially
hosting first stars, we present a novel approach to investigate DLAs in the
context of Milky Way (MW) formation, along with their connection with the most
metal-poor stars and local dwarf spheroidal (dSph) galaxies. The merger tree
method previously developed is extended to include inhomogeneous reionization
and metal mixing, and it is validated by matching both the Metallicity
Distribution Function of Galactic halo stars and the Fe-Luminosity relation of
dSph galaxies. The model explains the observed NHI-Fe relation of DLAs along
with the chemical abundances of [Fe/H] < -2 systems. In this picture, the
recently discovered z_abs ~ 2.34 C-enhanced DLA (Cooke et al. 2011a), pertains
to a new class of absorbers hosting first stars along with second-generation
long-living low-mass stars. These "PopIII DLAs" are the descendants of
H2-cooling minihalos with Mh ~ 10^7 Msun, that virialize at z > 8 in neutral,
primordial regions of the MW environment and passively evolve after a short
initial period of star formation. The gas in these systems is warm Tg \sim
(40-1000) K, and strongly C-enriched by long-living, extremely metal-poor stars
of total mass M* \sim 10^{2-4} Msun.Comment: 5 pages, 4 figures, accepted for publication in MNRAS lette

Predictors of Contemporary under-5 Child Mortality in Low- and Middle-Income Countries: A Machine Learning Approach
Child Mortality (CM) is a worldwide concern, annually affecting as many as 6.81% children in low- and middle-income countries (LMIC). We used data of the Multiple Indicators Cluster Survey (MICS) (N = 275,160) from 27 LMIC and a machine-learning approach to rank 37 distal causes of CM and identify the top 10 causes in terms of predictive potency. Based on the top 10 causes, we identified households with improved conditions. We retrospectively validated the results by investigating the association between variations of CM and variations of the percentage of households with improved conditions at country-level, between the 2005â2007 and the 2013â2017 administrations of the MICS. A unique contribution of our approach is to identify lesser-known distal causes which likely account for better-known proximal causes: notably, the identified distal causes and preventable and treatable through social, educational, and physical interventions. We demonstrate how machine learning can be used to obtain operational information from big dataset to guide interventions and policy makers
A versatile and user-friendly approach for the analysis of proteins in ancient and historical objects
Identification and characterization of ancient proteins still require technical developments towards non-invasiveness, sensitivity, versatility and ease of use of the analyses. We report that the enzyme functionalized films, described in Cicatiello et al. (2018), can be used efficiently on the surface of different objects ranging from fixative-coated paper to canvas to the coating on an albumen photograph, as well as the much harder surfaces of ivory objects and the proteinaceous binders in the decoration of a wooden Egyptian coffin. The mixture of digested peptides that are efficiently captured on the functionalized surface are also amenable to LC-MS/MS analysis, which is necessary to confidently identify chemical modifications induced upon degradation, in order to characterize the conservation state of proteins. Moreover, in a two-step procedure, we have combined the trypsin functionalized film with a PNGaseF functionalized film, which adds a deglycosylation pretreatment allowing improved detection of glycosylated proteins. SIGNIFICANCE: User friendly trypsin functionalized films were implemented to expand their potential as versatile, modular tools that can be widely exploited in the world of diagnosis of cultural heritage objects, ancient proteins, and palaeoproteomics: a procedure that could be carried out by conservators or archaeologists first on-site and later analysed with standard MS techniques
