Alice Miel and Democratic Schooling: An Early Curriculum Leader\u27s Ideas on Social Learning and Social Studies
No full textAlice Miel, a nationally prominent curriculum development scholar-practitioner at Teachers College of Columbia University for some three decades (1942-1971), frequently has been overlooked in research on the nature and evolution of the curriculum field and the progressive education movement. Furthermore, her contributions have been overlooked even as attention to women in the curriculum field and in educational history has risen. This study addresses this oversight.
Miel became a leading figure in the curriculum field largely on the basis of her progressive-era advocacy and practice of democratic social learning as a primary goal of schooling in the United States. This study explores major influences on her ideas, her understandings of democratic concepts and principles, and her application of these concepts and principles both in her own college classroom and in her research on childhood education. It also explores Miel\u27s notions of the elementary school social studies :urriculum and situates those notions within the context of the conventional wisdom of her day regarding a discipline-centered curriculum.
In a broader context, this study contributes to the body of curriculum history scholarship. According to Kliebard (1992), for example, curriculum history often deals with the relationship between social change and changing ideas and contains significant social and cultural artifacts of knowledge that have become embodied in the curriculum of schools. Davis (1976, 1977) characterizes curriculum history as a reflective enterprise for curriculum workers that contributes to their understanding of present courses of study and of the professional field by lending a framework for thoughtful deliberation of what the schools should teach. With these observations in mind, Miel\u27s work may be understood as both artifact of curriculum history and as mindful reflection, situated within a particular social and historical context, on democratic meanings and processes. Biographies of Caswell, Taba, Tyler, Schwab, Kilpatrick, Rugg, Bobbitt, Zirbes, Stratemeyer, and others have yielded significant insights. In addition, Seguel\u27s study of early curriculum leaders (1966) constitutes an important theoretical contribution to the field. The study of Miel\u27s life and work adds to this body of knowledge

Afro-American artists--a handbook, 1985
No full textThis dissertation, which is structured as a handbook, provides the basic information needed to prepare and teach a unit on Afro-American artists to an undergraduate class in art history or interdisciplinary humanities. Chapter I is an overview of American art which includes the Afro-American artists who came to prominence during each of the five periods from the nineteenth century to the present. The names, dates and birthplaces of one hundred and twelve Afro-American artists are included on tables in this chapter. Chapter II recounts biographical and career infor-mation on twenty Afro-American artists as exemplars of the range of life-styles and contributions of Afro-American artists. The artists so treated are: Edmonia Lewis, Robert S. Duncanson, Edward M. Bannister, Henry 0. Tanner, Aaron Douglas, Archibald Motley, Jr., William H. Johnson, Hale Woodruff, Richmond Barthe, Horace Pippin, Lois Mailou Jones, Beauford Delaney, Romare Bearden, Elizabeth Catlett, Jacob Lawrence, Alma Thomas, Charles White, Richard Hunt, Sam Gilliam, and Betye Saar. Chapter III presents twenty illustrations--one for each exemplar artist--with a brief discussion of the work illustrated. The discussion identifies the medium, style, technique, and place in the artist's oeuvre of the particular work. Publications where the painting or sculpture appears, and the permanent collection in which each work is located are included. Chapter IV contains a detailed discussion of resources for the study of Afro-American art, including critical and biographical books, exhibition catalogues, and bibliographical works. Tables in Chapter IV indicate representation of over five hundred Afro-American artists in selected exhibitions and in critical and biographical books on Afro-American art.

Towards Understanding and Overcoming the Antibiotic Resistance Conferred by Acetyltransferases.
No full textAminoglycoside (AG) antibiotics have been widely applied to the treatment of bacterial infections since the discovery of streptomycin. Having enjoyed over 60 years of clinical success, AGs have encountered problems with bacterial resistance, as do all antibiotics. The covalent chemical modification of the AG structure by AG-modifying enzymes (AMEs) poses a large threat to the future applicability of AGs. Chloramphenicol (CAM), another natural product with excellent antibacterial properties, suffers from a similar resistance problem. The modification of CAM by chloramphenicol acetyltransferase (CAT) renders it inactive. This dissertation focuses on acetyltransferases conferring resistance to antibiotics, discussing progress towards understanding and overcoming a major hurdle in our ability to combat bacterial infections.
Our laboratory reported the unusual regio-versatility of the AG N-acetyltransferase (AAC), Eis, from Mycobacterium tuberculosis (Mtb). We sought to understand the order, number, and regio-specificity of the acetylations carried out by Eis by NMR spectroscopy. We found that Eis not only acetylates multiple positions, but that the positions acetylated and order varies based on the particular AG scaffold. Furthermore, Eis is capable of acetylating amines that have never been reported. We also investigated other anti-TB drugs to determine if it was possible that Eis could cause resistance across drug classes. We found that capreomycin (CAP), a cyclic peptide antibacterial agent, could also be acetylated by Eis.
Using our knowledge of AMEs, we sought to develop novel AGs with improved/maintained activity and the ability to avoid modification by AMEs. A series of molecules were synthesized and tested against numerous bacterial strains. These studies and the knowledge gained regarding Eis will serve as a guide to the development of novel AGs targeting Mtb and other pathogens.
Additionally, we determined the first X-ray crystal structure of CATI with its natural substrate, CAM, bound in the active site, along with a structure of the unbound form of CATI. Comparison to a structure with fusidic acid (FA) bound and CATIII with CAM bound allowed for a deeper understanding of the broader substrate preference of CATI. We hope that the insights provided in our studies may one day aid in the development of novel CAM analogs.PhDMedicinal ChemistryUniversity of Michigan, Horace H.

The political orientations of blacks in three bi-racial predominantly rural counties in Georgia: the cases of Brooks, Burke and Peach counties, 1975
No full textBased on a definition culled from modern black liberation rhetoric (1966 to present), the study explores the extent of black nationalist sentiment, level of political participation, and socio-emotional commit�ment to political action among blacks in the rural situational context. Research findings are based on a one percent random sample of non�leadership using a cluster bloc approach, and a selected sample of black leaders in each county identified through a reputational approach. The study is basically descriptive due to the nature of the data on hand. Political institutions in the Southern rural milieu are under the domination of an agrarian elite and its agents whose basic relationship with the black population may best be described as of a patron-client variety. The Southern white value framework in support of the clientage system is traditionalism which had been forged out of the logic of the slave economy, and refined and distilled during the Civil War, Reconstruc-tion and Counter-Reconstruction. It has been perpetuated through the maintenance of blacks in a position of subjugation to assure their avail-ability as a cheap labor supply. Political and social development of the rural South is, in part, the result of the intervention of the Federal government, the civil rights struggle and the black power movement. Heightened political awareness in Southern rural black communities followed the Civil Rights Movement of the early 1960's; the passage of the Civil Rights Act of 1964; the Voting Rights Act of 1965; and Federal enforcement of public school desegregation. This heightened political activity in the black community is evidenced in the black political history of all three counties since 1966. It was found that black political participation in Brooks, Burke and Peach counties today does not conform to the portrait of blacks given in the literature on Southern politics. In that literature, blacks are portrayed as non-political, apathetic black individuals who dare not dis-cuss politics for fear of economic reprisals from the white community, and who use non-political institutions to channel and sublimate their aggressions and ambitions. The literature also suggests that blacks are socialized as parochial subjects of the political system, with expecta�tions that the political system will act upon them without their partici�pation. Although differences were found among the three counties, generally, there was a definite trend toward political participation and politiciza-tion among respondents. There also appeared to be a basic level of black identity in existence in which respondents saw themselves as belonging to a large collectivity of blacks whose bonds transcended their sub-community. Blacks in rural Georgia also expressed a deep level of belief that they have a heritage to be proud of
Analysis of the relationship between upper elementary students' skills in classifying and inferring and their achievement in reading comprehension and vocabulary

A qualitative process evaluation of electronic session-by-session outcome measurement in child and adolescent mental health services
No full textBackground: Regular monitoring of patient progress is important to assess the clinical effectiveness of an intervention. Recently, initiatives within UK child and adolescent mental health services (CAMHS) have advocated the use of session-by-session monitoring to continually evaluate the patient’s outcome throughout the course of the intervention. However, the feasibility and acceptability of such regular monitoring is unknown. Method: Semi-structured qualitative interviews were conducted with clinicians (n= 10), administrative staff (n=8) and families (n= 15) who participated in a feasibility study of an electronic session-by-session outcome monitoring tool, (SxS), which is based on the Strengths and Difficulties Questionnaire (SDQ). This study took place in three CAMHS clinics in Nottinghamshire. The interview transcripts were thematically analysed. Results: We found clinicians accepted the need to complete outcome measures, particularly valuing those completed by the patient. However, there were some difficulties with engaging clinicians in this practice and in the training offered. Generally, patients were supportive of completing SxS in the waiting room prior to the clinic session and assistance with the process from administrative staff was seen to be a key factor
An investigation into the relationship between fiction and nonfiction reading exposure, and factors of critical thinking
No full textReading fiction has been associated with improved social and imaginative reasoning that could lead to improved critical thinking. This observational study investigated the relationship between fiction and nonfiction exposure, narrative transportation, and factors of critical thinking (critical thinking disposition, and epistemological orientation). Self-selecting participants (N = 335) completed an online survey including an author recognition test and self-report scales. Fiction scores were significantly associated with higher critical thinking disposition, while nonfiction had an inverse effect correlating with lower disposition. Fiction reading was associated with decreased absolutism, and nonfiction score conversely with higher absolutism. Total and nonfiction print exposure were associated with lower multiplism, with no significant association for fiction. Total and fiction print exposure were associated with higher evaluativism, with no significant association for nonfiction. Narrative transportation mediated some of these relationships. These findings provide a basis for further research into reading fiction and nonfiction, and critical thinking
Blowin' in birdland: Improvisation and the Australian pied butcherbird
No full textThis paper challenges the assumption that improvisation is a process unique to humans. Despite the general reluctance of biologists to consider birdsong "music," they routinely comment on improvisation found in the signals of songbirds. The Australian pied butcherbird (Cracticus nigrogularis) is such a species. Analysis (including transcriptions and sonograms) of solo song, duets and mimicry illustrates their remarkable preoccupation with novelty and variety, and traces improvisation's role in the creation of their complex song culture. The author suggests further zoömusicological case studies for the relevance this research could have to other human (musical) capacities. ©2010 ISAST
