Perceptions of the implementation of a whole-school reform model : all-female single-sex education

Lofton, Susan Claire 19 November 2013 (has links)
The purpose of this study was to explore the implementation experiences of school leaders and teachers in a public, all-female, single-sex campus that experienced successful student outcomes. This research examined the participants' views of the factors that influence successful implementation of this model. Three research questions guided the study: (1) What are stakeholder perceptions of the factors that influenced the successful implementation of an all-female, single-sex, whole-school reform? (2) What are stakeholder perceptions of the successes experienced during the successful implementation of an all-female, single-sex, whole-school reform? (3) What are stakeholder perceptions of the challenges to the successful implementation of an all-female, single-sex, whole-school reform? This qualitative study used a grounded theory approach and a case study design to examine the implementation of whole-school, single-sex reform on a campus that experienced successful student outcomes, as evidenced by receiving the highest rating from the state accountability system in 2010-2011. Participants for this study were selected through purposive, theoretical sampling using a referral technique to generate the participant pool. Data were collected through semi-structured interviews, an open-ended questionnaire, and a review of documents. To produce a substantive theory, data analysis followed the open, axial, and selective coding processes outlined by Strauss and Corbin (1990). The participant perceptions and major findings were analyzed to determine the relationships between causal conditions in order to develop theoretical explanations about the factors that influenced the implementation. The major factors influencing the implementation of the all-female, single-sex campus in this study were: (1) Community, (2) External factors, (3) District-level factors, and (4) School-level factors. The data and findings from this research were used to generate a substantive theory regarding the factors that influence successful implementation of this model so that leaders in public school districts may have a greater knowledge base with which to augment the decision-making process when considering the implementation of all-female, single-sex campuses as a whole-school reform model. Also, districts planning to implement this model may use the findings as a guide when considering the factors in their own districts that may influence implementation. / text

Food Deserts and Eating Habits of Children Participating in the WIC Program

Jewell, Kassi Kae 16 December 2013 (has links)
The USDA’s “My Plate” recommends that preschool-aged children consume specific amounts of fruits, vegetables, and whole grains. These foods contain essential nutrients that children and adults alike require to maintain good health. Researchers have shown, however, that a significant number of children do not consume the recommended amounts of these foods, specifically vegetables and whole grains. Investigators have become increasingly interested in food deserts and whether living in these areas results in lower consumption of healthy foods. Food deserts by definition are areas where inhabitants have limited access to nutritious food. This study investigated the fruit, vegetable and whole grain consumption levels for preschool age children living in food desert or non-food desert areas. The NATFAN (National Food and Nutrition Questionnaire) survey of WIC participants was compared to the USDA’s food desert location data in order to learn the impact of living in a food desert. Using IBM SPSS to test the hypothesis, separate two-sample t-tests were conducted to determine if the mean difference between frequencies of fruit, vegetable, and whole grain consumption equaled zero. The data showed no difference in consumption of fruits and vegetables between food desert residing children and their non-food desert counterparts. There was, however, a difference in means for the consumption of whole grains. Specifically, food desert residing participants were consuming less brown rice. Using consumption amounts estimated from frequency data, it was discovered that, overall, WIC participants were under consuming fruits, vegetables, and whole grains.

Causal relevance and the mental : towards a non-reductive metaphysics

Garrett, Brian. January 1996 (has links)
My aim in this thesis is to explain how a non-reductionist metaphysics can accommodate the causal relevance of the psychological and of the special sciences generally. According to physicalism, all behavior is caused by brain-states; given "folk-psychology", behavior (such as the waving of my hand) is caused by some psychological state. If psychological states are distinct from brain states (event dualism), then our behavior is overdetermined and this, it is claimed, is unacceptable. I argue that this consequence is not unacceptable. I claim that our explanatory practice should guide our ontological commitment. If we can offer true explanations that appeal to more than one event (or property), then we are committed to overdetermination for the event explained. I argue that accepting overdetermination is not absurd and that we can give an adequate account of causal relevance for psychological and other supervenient properties. The result is a partial defense of both property and event pluralism. Recent work by Davidson, Fodor, Jackson, Kim, Pettit and Yablo receives explicit and critical discussion.

The spatially restricted theory of composition

Ksiazek, Richard 06 April 2011 (has links)
Determining when some xs compose a y provides the answer to the Special Composition Question. There are three types of possible answers: always, sometimes, never. All of the competing views fall into one of these three categories. I present these competing theories, and explain the advantages and objections to each, and in the cases of those falling into the “always”, and “never” categories explain why the categories cannot provide a satisfactory response. Then I present my own answer to the Special Composition Question and show that it is not vulnerable to the objections the competitor theories cannot overcome. I also present a novel solution to the General Composition Question.

Geobacillus genties bakterijų kamienų giminingumo nustatymas visų ląstelės baltymų analizės metodu / Relationship determination of the strains of the genus geobacillus by electrophoretic whole cell protein profile analysis

Jasinskytė, Džiuginta 20 June 2014 (has links)
Santrauka Visų ląstelės baltymų analizė – tai metodas teikiantis fenotipinės informacijos. Jis plačiai naudojamas grupuoti bakterijų kamienus, nustatyti jų pirminį identitetą. Rezultatų patikimumas daugeliu atvejų prilygsta DNR-DNR hibridizacijai – pagrindiniam genotipinės informacijos metodui. Tuo pačiu visų ląstelės baltymų analizės metodas yra greitai atliekamas ir pigus. Dėl šių priežasčių metodas plačiai naudojamas medicininės diagnostikos, o taip pat su maisto pramone susijusiose laboratorijose. Šiuolaikiniame pasaulyje pramonėje labai svarbūs yra termostabilūs fermentai, o Geobacillus genties bakterijų kamienai būdami termofilai, yra tokių fermentų producentai. Dėl šios priežasties Geobacillus gentis yra aktualus tyrimų objektas. Labai svarbu tiksliai identifikuoti kamienus produkuojančius tiriamus fermentus. Vienu iš pirminio identifikavimo būdų galėtų būti visų ląstelės baltymų analizės metodas. Šiame darbe buvo parodyta, kad Geobacillus genties kamienų tarpusavio panašumas gali būti nustatytas visų ląstelės baltymų analizės metodu. Tarp G. stearothermophilus rūšies kamienų visų ląstelės baltymų elektroforetinių profilių panašumas buvo apie 80% ir atitiko DNR-DNR hibridizacijos rezultatus. Taip pat sutapo ir 22 kamieno panašumas su tipiniu G. vulcani kamienu: WCPP parodė 84% panašumą, DNR-DNR hibridizacija – 93,9%. Pagal visų ląstelės baltymų analizės metodą gauti rezultatai paneigė G. stearothermophilus 10 DSM 13240 kamieno priklausomybę šiai rūšiai. Pagal panašumo... [toliau žr. visą tekstą] / Summary Electrophoretic whole-cell protein profile analysis (WCPP) – is a method providing phenotypic information. It is widely used to group bacterial strains and estimate their primal identity. In most cases reliability of this method is equal to DNA-DNA hybridization – that is the main method of genotypic information. WCPP is performed quickly and it is cheap. Therefore this method is widely used in laboratories of medical diagnostic and laboratories related to food industry. In modern world termostable enzymes are very important in industry, whereas thermophilic bacterial strains of the genus Geobacillus are producers of these enzymes. Consequently genus Geobacillus is an actual object of research. It is very important to strictly identify bacterial strains producing needed enzymes. One of the primal ways for identification of this genus could be WCPP. During this work it was shown that similarity of strains of the genus Geobacillus can be determined by WCPP. There was an 80% similarity among strains of G. stearothermophilus. These results matched with DNA-DNA hybridization of these strains. Also there were similar results of WCPP and DNA-DNA hybridization between strain 22 and typical strain of G. vulcani: 84% and 93,9% respectively. Results of WCCP denied dependence of strain G. stearothermophilus 10 DSM 13240 to this species. According to similarity dendrogram this strain should be assigned to G. vulcani because of its 97% similarity to this species. There were also... [to full text]

The MANE process of generating continuous energy hot-operating temperature cross sections

Chapman, Christopher Weeks 12 January 2015 (has links)
MANE (MCNP ACE from NJOY & ENDF), a code for generating continuous energy cross sections at arbitrary temperatures, was created. Cross sections were evaluated using NJOY99 such that they would agree with the cross sections provided by MCNP5. The MANE cross sections were found to be in very good agreement with those provided by MCNP5 with some minor exceptions caused by round-off errors and some differences in the unresolved resonance region. Differences in the resonance region are caused by differences in the random number generator used to start the cross section calculations. The MANE cross sections were verified against the MCNP5 cross sections in five unique MCNP configurations: an 8.7% enriched MOX fuel pin cell, a UO₂ assembly (controlled and uncontrolled), a MOX assembly, and a whole core configuration containing the 3 assemblies. In each of these cases, eigenvalue and tally density results were found to be in very good agreement with one another.
