D.) University of Missouri-Columbia 2008.Education has proven one path out of poverty for low-income single mothers, yet many are not completing and transferring at high rates. Using theories of economic development as the lens for analysis, I sought to study how single mothers used certain government and institutional policies to facilitate their attendance at a rural community college in a Midwestern state, and how these policies shaped the women's choices about college attendance. More specifically, I wanted to understand how the single mothers' college-going decisions related to access, persistence, completion, and transfer were affected by the federal, state, and local policies they used to manage their economic circumstances. This was a qualitative study using a multiple-case study approach, and there were ten cases studied. For the participants in the study, the Pell Grant was an important avenue of access to the community college; however, it was not sufficient to serve as an avenue of access to the baccalaureate. As well, the lack of access to health coverage, child custody agreements, and an unwillingness to relocate proved to be important barriers to degree completion.Includes bibliographical reference
“Warming up” in the developmental sequence? Upward transfer conditional on dependency status
The purpose of this study was to determine predictor factors of upward transfer for Kentucky community college students enrolled in a developmental algebra course. For independent students, a mother with a college degree, a declared major, a federal work-study position, greater adjusted gross income, and a higher grade point average was positively correlated with upward transfer. For dependent students, a father with a college degree, a declared major, and a higher grade point average was positively correlated with upward transfer

Response of benthic foraminifera to ocean acidification in their natural sediment environment: a long-term culturing experiment
Calcifying foraminifera are expected to be endangered by ocean acidification, However,
the response of a complete community kept in natural sediment and over multiple generations
under controlled laboratory conditions has not been constrained to date. During
5 six month incubation, foraminiferal assemblages were treated with pCO2 enriched
seawater of 430, 907, 1865 and 3247 μatm pCO2. The fauna was dominated by Ammonia
aomoriensis and Elphidium species, whereas agglutinated species were rare. After
6 months incubation, pore water alkalinity was much higher in comparison to the overlying
seawater. Consequently, the saturation state of Òcalc was much higher in the sedi10
ment than in the water column in all pCO2 treatments and remained close to saturation.
As a result, the life cycle of living assemblages was largely unaffected by the tested
pCO2 treatments. Growth rates, reproduction and mortality, and therefore population
densities and size-frequency distribution of Ammonia aomoriensis varied markedly during
the experimental period. Growth rates varied between 25 and 50 μm per month,
15 which corresponds to an addition of 1 or 2 new chambers per month. According to
the size-frequency distribution, foraminifera start reproduction at a diameter of 250 μm.
Mortality of large foraminifera was recognized, commencing at a test size of 285 μm
at a pCO2 ranging from 430 to 1865 μatm, and of 258 μm at 3247 μatm. The total organic
content of living Ammonia aomoriensis has been determined to be 4.3% of dry
20 weight. Living individuals had a calcium carbonate production rate of 0.47 gm−2 yr−1,
whereas dead empty tests accumulated at a rate of 0.27 gm−2a−1. Although Òcalc was
close to 1, some empty tests of Ammonia aomoriensis showed dissolution features at
the end of incubation. In contrast, tests of the subdominant species, Elphidium incertum,
stayed intact. This species specific response could be explained by differences in
25 the elemental test composition, in particular the higher Mg-concentrations in Ammonia
aomoriensis tests. Our results emphasize that the sensitivity to ocean acidification
of endobenthic foraminifera in their natural sediment habitat is much lower compared
to the experimental response of specimens isolated from the sediment
Is Retention Enough? Learning and Satisfaction of First-Generation College Seniors
Progress has been made in retaining and graduating traditional-age first-generation college students at four-year institutions. First-generation students, however, often experience college differently because of external factors, which can negatively influence their learning experience and overall satisfaction. This study explored learning and satisfaction measures of seniors at a small private university in the Midwest. Using Astin’s I-E-O model (1970), the following variables were considered: precollege student characteristics (input); academic engagement, co-curricular activities, campus relationships (environment); and satisfaction, learning (outcome). The sample consisted of seniors participating in NSSE and/or ETS MAPP (n=342). Findings confirmed that first-generation students typically worked more for pay, commuted, and had greater financial need. Results of the analysis of learning and satisfaction however, indicated no difference between the two groups (
People of the British Isles: preliminary analysis of genotypes and surnames in a UK control population
There is a great deal of interest in fine scale population structure in the UK, both as a signature of historical immigration events and because of the effect population structure may have on disease association studies. Although population structure appears to have a minor impact on the current generation of genome-wide association studies, it is likely to play a significant part in the next generation of studies designed to search for rare variants. A powerful way of detecting such structure is to control and document carefully the provenance of the samples involved. Here we describe the collection of a cohort of rural UK samples (The People of the British Isles), aimed at providing a well-characterised UK control population that can be used as a resource by the research community as well as
providing fine scale genetic information on the British population. So far, some 4,000 samples have been collected, the majority of which fit the criteria of coming from a rural area and having all four grandparents from approximately the same area. Analysis of the first 3,865 samples that have been geocoded indicates that 75% have
a mean distance between grandparental places of birth of 37.3km, and that about 70% of grandparental places of birth can be classed as rural. Preliminary genotyping of 1,057
samples demonstrates the value of these samples for investigating fine scale population structure within the UK, and shows how this can be enhanced by the use of surnames
Sustaining The Saco Estuary: Final Report 2015
This study focuses on the Saco estuary, the tidal portion of the Saco River, which drains the largest watershed in southern Maine. With headwaters in the White Mountains of New Hampshire, the watershed encompasses more than 4,400 km2, and provides clean healthy drinking water to over 100,000 people living and working in communities in southern Maine.
When the study began in 2009, very little was known about the ecology of the Saco estuary. Researchers at the University of New England and the Wells National Estuarine Research Reserve employed the process of collaborative learning to bring together people who care about the estuary in order to identify their concerns. A Stewardship Network composed of people employed by municipal, state and federal governments, water supply organizations and businesses, volunteers from municipal boards making land use decisions, land trusts, property owners and representatives from other organizations that are uniquely focused on the region was formed. The Stewardship Network helped to define the project goals and objectives, and provided input and guidance over the five-year project.
This report explains what the researchers discovered about the ecology of the estuary, along with what they learned about its social and economic components. This baseline assessment contributes to the long-term goal of restoring and sustaining the structure and function of the estuary, and supports the efforts of government, businesses and local organizations that value the estuary and depend upon the natural services it provides
Etiology and antimicrobial susceptibility of udder pathogens from cases of subclinical mastitis in dairy cows in Sweden
<p>Abstract</p> <p>Background</p> <p>A nationwide survey on the microbial etiology of cases of subclinical mastitis in dairy cows was carried out on dairy farms in Sweden. The aim was to investigate the microbial panorama and the occurrence of antimicrobial resistance. Moreover, differences between newly infected cows and chronically infected cows were investigated.</p> <p>Methods</p> <p>In total, 583 quarter milk samples were collected from 583 dairy cows at 226 dairy farms from February 2008 to February 2009. The quarter milk samples were bacteriological investigated and scored using the California Mastitis Test. Staphylococci were tested for betalactamase production and presence of resistance was evaluated in all specific udder pathogens. Differences between newly infected cows and chronically infected cows were statistically investigated using logistic regression analysis.</p> <p>Results</p> <p>The most common isolates of 590 bacteriological diagnoses were <it>Staphylococcus (S) aureus </it>(19%) and coagulase-negative staphylococci (CNS; 16%) followed by <it>Streptococcus (Str) dysgalactiae </it>(9%), <it>Str. uberis </it>(8%), <it>Escherichia (E.) coli </it>(2.9%), and <it>Streptococcus </it>spp. (1.9%). Samples with no growth or contamination constituted 22% and 18% of the diagnoses, respectively. The distribution of the most commonly isolated bacteria considering only bacteriological positive samples were: <it>S. aureus </it>- 31%, CNS - 27%, <it>Str. dysgalactiae </it>- 15%, <it>Str. uberis </it>- 14%, <it>E. coli </it>- 4.8%, and <it>Streptococcus </it>spp. - 3.1%. There was an increased risk of finding <it>S. aureus, Str. uberis </it>or <it>Str. dysgalactiae </it>in milk samples from chronically infected cows compared to findings in milk samples from newly infected cows. Four percent of the <it>S. aureus </it>isolates and 35% of the CNS isolates were resistant to penicillin G. Overall, resistance to other antimicrobials than penicillin G was uncommon.</p> <p>Conclusions</p> <p><it>Staphylococcus aureus </it>and CNS were the most frequently isolated pathogens and resistance to antimicrobials was rare.</p
Go-stimuli proportion influences response strategy in a sustained attention to response task
The sustained attention to response task (SART)
usefulness as a measure of sustained attention has been questioned. The SART may instead be a better measure of other psychological processes and could prove useful in understanding some real-world behaviours. Thirty participants completed four Go/No-Go response tasks much like the SART, with Go-stimuli proportions of .50, .65, .80 and .95. As Go-stimuli proportion increased, reaction times decreased while both commission errors and self-reported task-related thoughts increased. Performance measures were associated with task-related thoughts but not taskunrelated thoughts. Instead of faster reaction times and increased commission errors being due to absentmindedness or perceptual decoupling from the task, the results suggested participants made use of two competing response strategies, in line with a response strategy or response inhibition perspective of SART performance. Interestingly, performance measures changed in a nonlinear manner, despite the linear Go proportion increase. A threshold may exist where the prepotent motor response becomes more pronounced, leading to the disproportionate increase in response speed and commission errors. This research has implications for researchers looking to employ the SAR
