    Daniel Deronda: A Consideration of George Eliot\u27s Concept of Culture

    Get PDF
    Daniel Deronda (published 1876) is George Eliot\u27s last and in many ways most controversial novel. Contemporary readers resent her writing anything which would compete with Middlemarch, an immensely popular novel and Deronda\u27s immediate predecessor. Even today Deronda suffers due to its location in the George Eliot canon. Whereas Middlemarch is universally acclaimed, Daniel Deronda is often dismissed as a failure (limited or otherwise) when it is compared with the book Virginia Woolf calls one of the few English novels written for grown-up people

    The Work Adjustment of Expatriate Teachers Employed in Chinese Internationalized Schools: A Hermeneutical Phenomenology

    Get PDF
    The purpose of this hermeneutical phenomenological study was to understand the work adjustment of expatriate teachers employed in Chinese internationalized schools. The theory guiding the study was Dawis and Lofquist’s theory of work adjustment. This theory explained the process of employee adjustment at the workplace as the result of job dissatisfaction leading to attempts at restoring the person-environment fit. The central research question was: How do expatriate teachers experience work adjustment in Chinese internationalized schools? The four sub-questions addressed the facets of work adjustment: activeness, reactiveness, perseverance, and flexibility. Chinese internationalized schools were an appropriate setting for the study because of the extraordinary work adjustment challenges in these institutions. The study employed a purposefully selected sample of 16 expatriate teachers who have worked in Chinese internationalized schools for at least one school year and have experienced work adjustment. Three data collection methods aided in gathering in-depth descriptions of participants’ lived experiences: individual interviews, written protocols, and focus groups. Data analysis relied on eclectic coding and van Manen’s hermeneutical framework. Four major themes summarized participants’ work adjustment experiences: discovering what lies behind the façade, trying to be a real teacher, navigating relationships with the paying customers, and trying to function in a multicultural work environment. Ryan and Deci’s self-determination theory aided the interpretation of findings and linked participants’ adjustment attempts to unfulfilled needs for relatedness, competence, and autonomy

    Weep Hole Inspection for Radial Fatigue Cracks by Circumferential Creeping Waves

    Get PDF
    Weep holes are drilled through risers in wet-wing structures in order to permit remanent fuel to be evenly distributed during flight. Unfortunately, they can become the sites from which fatigue cracks tend to originate. Figure 1 shows the schematic diagram of weep holes cut into the vertical risers of an airplane wing used as a fuel tank. The cracks have been found to grow in either the upward or downward or both directions. These fatigue cracks initially grow in a radial direction perpendicular to the wing skin surface. Downward growing cracks can be easily detected using a 45-degree shear wave transducer. The main objective of this study was the development of an ultrasonic detection technique for the less accessible upward growing cracks. The blowup in Figure 1 shows the geometrical configuration of such an upward growing fatigue crack

    Studium aktivních center v zeolitových katalyzátorech pro kaskádovou Prins-Friedel-Craftsovu reakci

    Get PDF
    Conventional zeolites are important shape-selective heterogeneous acid catalysts due to the presence of acid sites accessible through uniform micropores. Recently designed hierarchical zeolites with combined micro-mesoporosity also contain acid sites on the external surface or in mesopores. These highly accessible acid sites are promising active centres for the transformation of bulky molecules, which cannot pass through the micropore openings of conventional zeolites. An example of a reaction that can benefit from the use of zeolites is the one-pot cascade Prins-Friedel-Crafts (PFC) reaction of an aldehyde, homoallylic alcohol, and aromatic compound, which yields valuable heterocyclic compounds containing 4- aryltetrahydropyran moieties. In this work, the acidic characteristics of a series of hierarchical aluminium- and gallium- containing MFI and MWW zeolites were evaluated by FTIR-monitored thermodesorption of probe molecules and further related to the catalytic properties of zeolites in the PFC reaction of butyraldehyde, 3-buten-1-ol, and anisole. The nature, strength, and total concentration of acid sites in the catalysts were evaluated using thermodesorption of pyridine (kinetic diameter 0.54 nm), while the characteristics of the external surface Brønsted acid sites were probed using...Konvenční zeolity jsou důležité tvarově selektivní heterogenní katalyzátory díky přítomnosti jejich kyselých center, která jsou přístupná skrze stejnoměrné mikropóry. Nově navržené hierarchické zeolity kombinující mikro a mezoporozitu obsahují tyto centra kyselosti také na svém vnějším povrchu, nebo v mezopórech. Tyto vysoce přístupná centra kyselosti se jeví jako slibná aktivní centra pro transformaci rozměrnějších molekul, která nejsou schopna vstoupit do mikropórů konvenčních zeolitů. Jako příklad reakce, pro kterou by použití zeolitů bylo prospěšné, je kaskádová Prins-Friedel-Craftsova reakce aldehydu, homoallylického alkoholu, a aromatické sloučeniny, která vede k cenným heterocyklickým sloučeninám obsahující 4-aryl tetrahydopyranovou skupinu. Tato práce se zabývá analýzou kyselých vlastností série hierarchických MFI a MWW zeolitů obsahujících hliník, nebo galium metodou FTIR analyzované desorpce adsorbovaných molekul. Tyto vlastnosti byly následně uvedeny do souvislostí s katalytickými vlastnostmi těchto zeolitů v PFC reakci butyraldehydu, 3-buten-1-olu, a anisolu. Typ, síla, a celková koncentrace kyselých center studovaných katalyzátorů byla vyhodnocena termodesorpcí pyridinu (kinetický průměr 0.54 nm), zatímco vlastnosti Brønstedových center kyselosti na vnějším povrchu byly vyhodnoceny...Department of Physical and Macromolecular ChemistryKatedra fyzikální a makromol. chemiePřírodovědecká fakultaFaculty of Scienc

    Celebrate Your Plate: Nutrition Education Through Social Marketing

    Get PDF
    The State Nutrition Action Committee (SNAC) was created in 2007 to bring together several health- and community-based organizations throughout the state of Ohio including SNAP-Ed, EFNEP, Department of Aging, Department of Education, Department of Health including WIC, Creating Healthy Communities and the Early Childhood Obesity Prevention Program, Department of Aging, Department of Job and Family Services, and the Mid-Ohio Foodbank. SNAC's aim is to promote shared goals and collaborate on related programming efforts. In the spring of 2016, SNAC decided to embark on a social marketing campaign together. SNAP-Ed facilitates the partnership between The Ohio State University and the program assistants (PAs), program coordinators (PCs) and FCS educators who are in 80 of Ohio's 88 counties delivering direct education and community programming. The SNAP-Ed social marketing campaign, Celebrate Your Plate (CYP), will support existing direct education programming across the state and encourage low-income audiences to increase their fruit and vegetable consumption. Social marketing is defined as "the application of commercial marketing technologies to the analysis, planning, execution, and evaluation of programs designed to influence voluntary behavior of target audiences to improve their personal welfare and that of society." (Andreasen, 1995). Work on a SNAP-Ed social marketing campaign began in early 2016 with the formation of the Social Marketing Core Team (SMCT) and the development of a campaign plan with the members of SNAC. The objectives of the SNAP-Ed social marketing campaign are as follows: 1) Plan, design, implement, and evaluate a social marketing campaign that increases fruit and vegetable consumption in low-income audiences by supporting the existing OSU Extension SNAP-Ed direct education program. 2) Create and document the processes of the social marketing campaign and its pilot and staged implementation throughout Ohio. Formative research was conducted during the summer of 2016 to inform the direction of the campaign; and a marketing agency, Fahlgren Mortine, was hired through the Ohio State University bid process to handle materials development and media purchasing. Data from formative research informed the direction of the campaign and determined the tone of the campaign, media approaches, and material design. Based on results from the pilot, a selection of marketing materials will be used in different quadrants across the state during the next two years. Fruit and vegetable consumption is the dietary guideline with the lowest achievement rate among all Ohioans. Celebrate Your Plate will facilitate additional partnerships to advance health and wellness through increasing fruit and vegetable consumption.AUTHOR AFFILIATION: Alisha Ferguson, SNAP-Ed Program Assistant, Social Marketing, [email protected] (Corresponding Author); Beth Hustead, SNAP-Ed Program Coordinator, Social Marketing; B.R.
