Item Knowledge and Attitudes of Montessori Teachers of Young Children as a Context for Guiding the Normalization and Self-Construction Process(1994) Schaefer Zener, Rita; Flatter, Charles; Human Development & Quantitative Methodology; Digital Repository at the University of Maryland; University of Maryland (College Park, MD)The purpose of this study was (1) to investigate the degree of agreement between AMI trained Montessori teachers' knowledge and attitudes and Montessori's recommendations for guiding the process of normalization among young children and (2) to discover the reasons for differences from those recommendations. Normalization is the central process in the Montessori method. Except for a study by this investigator (Zener, 1993) guiding the process of normalization had not been researched since Montessori's work some forty-five to eighty-five years ago. Therefore, this investigation also provided current teacher experiences of guiding the process of normalization. One hundred sixty five Montessori teachers attending various regional and national conferences were surveyed with knowledge and attitude scales. Semi-structured interviews were conducted with 10% of the participants. Mean scale scores from 4.0 to 5.0 on a five degree Likert scale and a SD less than 1.0 were projected as satisfactory levels of agreement with Montessori's recommendations. Descriptive statistics were used to analyze the scales, and content analysis was used to analyze the interviews. T-tests and ANOVAS indicated that demographic variables were not significant to the results.Item Riots and Revolution: Food Riots in the Department of the Seine-et-Oise, 1789-1795(1994) Sanyal, Sukla; Cockburn, James; History; Digital Repository at the University of Maryland; University of Maryland (College Park, MD)This dissertation is a diachronic study of the food riots that broke out in the department of the Seine-et-Oise from 1789 through 1795. The purpose of the dissertation is to study one of the most common forms of popular protest in France in all its complexity. This study traces the riots downs the years and situates them within a specific political and economic context. It argues that as the Political and economic circumstances changed, the riots changed in form and content from market riots to stoppages of convoys to invasions into the homes of farmers. The dissertation also examines how the Revolution affected the rioters, not only in their material lives, but in their thinking and ideology as well. Chapter II traces the breadth and scope of the riots. Chapter III is a study of the connections between the policies of the revolutionary governments towards the commerce of foodstuff and the outbreak of the riots. It is shown that the riots changed in form over the years as the rioters sought to deal with the consequences of governmental legislation at different periods. Chapter IV examines the causes of the riots. It studies the long term and short term causes of the riots as well as the immediate causes. In this context, the chapter examines the social structure of the Seine-et-Oise , the effects of the policy of liberalization of the commerce of foodstuff and the effects of war. Chapter V studies the motivations, the organization and the composition of the riot groups. It argues that the Revolution had a direct impact on the mentalities of the rioters. As the years progressed the outlook of the rioters became steadily more radical, and they came to believe that political rights, and a Constitution which protected their interests, would alone solve the problem of subsistence in France. The sources for this study are the administrative records, police records, judicial records, legislative edicts, price lists and propaganda pamphlets found in the Archives Nationales at Paris, the Departmental Archives at Yvelines and Corbeil-Essonnes and the Bibliotheque de la Ville de Paris.Item A SELF-SELECTED QUALITATIVE STUDY EXAMING THE RELATIONSHIP BETWEEN A FATHER AND HIS SON WHO HAS ATTENTION DEFICIT HYPERACTIVITY DISORDER (ADHD)(1996) Kilcarr, Patrick; Flatter, Charles; Human Development & Quantitative Methodology; Digital Repository at the University of Maryland; University of Maryland (College Park, MD)The purpose of this interpretive study was to examine the relationship that exists between a father and his son Who has Attention Deficit Hyperactivity Disorder (ADHD). Since very little information is extant describing the relationship between a father and his son with ADHD, an interview format was developed to explore paternal perceptions, affect, and behaviors in relation to raising a son with ADHD. Sixteen fathers from an upper-middle class socioeconomic environment, participated in a one hour phone interview. These interviews were tape recorded and later transcribed. The interview attempted to answer the five research questions driving this study. The narrative data was interpreted by using a qualitative research method developed by Ranata Tesch. method involved extracting themes (specific participant responses) and collapsing the themes into larger-overarching categories called metathemes. Metathemes represent shared thoughts and perceptions held in common by all participants. Ten metathemes emerged from the data. The metathemes included such topics as a father's decision to place a child on medication and how and when to use behavior management strategies. Editorial comments from the author preceded response segments from participants (these segments were indented and single spaced). The data indicated that fathers share a unique relationship with sons who have ADHD. Prior to diagnosis, the majority of fathers described the relationship as tense, frustrating, and often unfulfilling. The relationship following diagnosis was described as significantly more Positive and rewarding. This was attributed to two specific changes: 1. the advent of education for fathers' regarding ADHD issues; and, 2. medication. Fathers agreed that the most effective behavior management strategy was to remain calm, educated, and realistic regarding their Childrens' behavior. The intention of this research was to generate further questions regarding the father-ADHD son relationship. The results of this study are not and cannot be generalized to other cultlures or social groups. Further research is needed which addresses the impact of race, class, and culture on the father and son with ADHD relationship.Item The interaction between a parasitic barnacle, Loxothylacus panopaei (Cirripedia, Rhizocephala), and three of its crab host species (Brachyura, Xanthidae) along the east coast of North America.(1993) Alvarez, Fernando; Reaka-Kudla, Marjorie; Animal & Avian Sciences; Digital Repository at the University of Maryland; University of Maryland (College Park, MD)Rhizocephalan barnacles parasitize primarily decapod crustaceans (Bocquet-Vedrine 1968, Overstreet 1983). The principal effect of the parasites is often the permanent sterilization of the hosts (Bocquet-Vedrine 1972, O'Brien & Van Wyk 1984). Regardless of the processes involved, the end result of the infection is the creation of non-reproductive individuals that will use resources that otherwise would be available to the healthy traction of the host population. The potential impact on the host population then resides in the accumulation of sterile resource-using individuals in each generation. Prevalences of barnacles on anomuran and brachyuran crabs have been reported in a number of studies (e.g., Walker 1985, Hawkes et al. 1986, Johnson et al. 1986, Wardle & Tirpak 1991 ). Rhizocephalan infections can reach very high levels locally, suggesting that entire host populations may have a greatly reduced reproductive capacity. However, in most host species, the pattern of distribution of parasites is not uniform throughout the host's range. I examined the crab-rhizocephalan interaction using the system composed by the barnacle Loxothylacus panopaei and three of its crab host species: Panopeus lacustris, Eurypanopeus depressus, and Rhithropanopeus harrisii, occurring along the east coast of the North America. Through experimental infections conducted in the laboratory, it was determined that B. harrisii of a wide range of sizes could be infected by L. panopaei. The complete life-cycle of the parasite was manipulated in the laboratory. Neither host molting frequency nor host molt increments differed significantly between parasitized and control crabs. Host survival was significantly reduced during the parasite's developmental period; the heaviest mortality of the host occurred in the megalopal stage.Item PERFORMANCE OF THE VIOLIN CONCERTO AND SONATAS OF JOHANNES BRAHMS WITH AN ANALYSIS OF JOSEPH JOACHIM'S INFLUENCE ON HIS VIOLIN CONCERTO(1997) Hsieh, I-Chun; Heifetz, Daniel; Music; Digital Repository at the University of Maryland; University of Maryland (College Park, MD)This dissertation consists of a performance project and extensive studies of selected works by Johannes Brahms, including the Violin Concerto, Sonatensatz, and three Violin Sonatas. The performance project was presented in two recitals at the University of Maryland, College Park, on November 14, 1997, and November 16, 1997. The first recital featured Brahms' s Sonatensatz in C Minor, Violin Sonata No. I, Op. 78 in G Major, and Violin Sonata No. 3, Op. 108, in D Minor. The second recital included Brahms' s Violin Sonata No.2, Op. 100, in A Major and Violin Concerto Op. 77, in D Major. Section One gives an overview of this dissertation project. Section Two introduces the violin virtuoso Joseph Joachim, his relationship with Johannes Brahms, and Brahms' s life and major violin works. This section also analyzes Joachim' s performance practice and his teaching style. The end of this section focuses on the influence of Joseph Joachim on Brahms' s Violin Concerto and indicates the differences between Brahms' s original manuscript and the version suggested by Joachim. Section Three is composed of the programs of the two recitals. Section Four consists of program notes for the two recitals. The first recital was performed by I-Chun Hsieh, violin and Roy Hakes, piano. The second recital was performed by I-Chun Hsieh, violin and Chia-Hsuan Lee, piano.Item Baroque Plague Imagery and Tridentine Church Reforms(1990) Boeckl, Christine M.; Pressly, William; Art History & Archaeology; Digital Repository at the University of Maryland; University of Maryland (College Park, MD)This dissertation aims to achieve two goals: one, to assemble as many facts as possible about the plague, regardless of period, and to relate this material to images; and two, to present a well-defined group of religious baroque plague paintings in the context of social, political and religious history. This inquiry is primarily concerned with scenes that portray saints actively involved in charitable pursuits, dispensing the sacraments to victims of the most dreaded disease, the bubonic plague. Chapter I contains a bibliographical essay, divided into three parts: medicine, theology, and art history. The next chapter considers the sources and the formation of baroque plague iconography. The remaining two chapters discuss "documentary" plague scenes and how they relate to historic events. They are presented in two sections: Italy and transalpine countries. This interdisciplinary research resulted in a number of observations. First, these narrative plague scenes were produced in Italy and in Catholic countries bordering Protestant regions: Switzerland, France, Flanders, and in the Habsburg Empire (excluding Spain). Second, the painters were mostly Italian or Italian-trained. Third, the artists observed not only the requirements specified by the Church in the 1563 Tridentine Decree on the Arts but also reflected in their work the catechetic teachings of the Council. Fourth, these religious scenes were not votive paintings but doctrinal images that served either didactic or polemic functions. Fifth, the scenes were not intended as memento mori; rather, the iconology conveyed positive images which emphasized that the faithful needed the Roman Catholic clergy to gain life-everlasting. Sixth, these plague paintings were important documents not as recordings of the conditions experienced during an epidemic but as historic testimony of liturgical practices. Last, these selected scenes mirrored the baroque Church's views on the ultimate questions about life and death.Item The Washington Bronze Dionysos(1994) Bennet, Susanne Klejman; Venit, Marjorie Susan; Art History & Archaeology; Digital Repository at the University of Maryland; University of Maryland (College Park, MD)A life-size bronze of a nude youth was discovered in a river in Asia Minor in the early 1960's. The bronze no longer had the iconographic attributes that it had once held in its hands, but the head presented features which made it possible to identity the figure as representing the god Dionysos. The sculptor drew upon earlier prototypes, specifically a figure called the Westmacott athlete, which has been tentatively attributed to the Greek sculptor Polykleitos. The head of the statue reflects a different, possibly female, prototype. An investigation of a group of Roman life-size and three quarter life-size bronzes reveals that the iconographic details which identity the Washington Bronze also place it outside the category of lamp hearers to which the majority of the other statues belong. The physiques of the majority of the lamp bearers and of the Washington Bronze, however, reflect the same Polykleitan prototypes. The identification of the Washington Bronze as a devotional rather than functional statue is made through a study of the literary, religious, and archaeological evidence. The evolution in the iconography of the god is traced through his portrayals on Greek vases and in Graeco-Roman bronze and marble statuary. The Bronze was created in the Eastern Roman Empire. Through a comparative analysis of other bronzes it can be dated within the period between the beginning of the Augustan era and the third quarter of the first century A. D. A setting in the home of a devotee of the Dionysian Mysteries is adduced.Item Topics in the Syntax and Semantics of Coordinate Structures(1993) Munn, Alan Boag; Hornstein, Norbert; Linguistics; Digital Repository at the University of Maryland; University of Maryland (College Park, MD)This thesis is concerned with developing a syntax for coordinate structures which is compatible with both the syntactic behaviour of conjunction structures and with their semantics. It argues that coordinate structures are asymmetrical, hierarchical structures that conform with X-bar theory. The conjunction head projects a phrase which is adjoined to the first conjunct. This provides an account of a number of syntactic asymmetries in conjunct ordering including agreement and binding asymmetries and provides a principled analysis of Across-the-Board extraction as instances of parasitic gaps. It further argues that the Coordinate Structure Constraint cannot be a syntactic constraint, but rather must be a condition on conjoining identical semantic categories. This provides an account of unlike category coordination which is shown to be freely possible if semantic identity is preserved and no independent syntactic constraints are violated, a result which follows from the adjunct nature of the coordinate structure. In order to account for the semantic identity, it is proposed that at Logical Form, each conjunct is a predicate in an identification relation with the conjunction head, which raises to take scope over all the conjuncts. Assuming theta role assignment at LF, only the conjunction head receives a theta role; none of the conjuncts does. Because each conjunct is in a predication relation with the conjunction head at LF, the semantic identity constraint follows directly. The fact that the conjuncts do not receive a theta role accounts for their inability to act as antecedents for reflexive binding and for fact that modal adverbs can appear inside conjoined NPs. The proposed analysis assimilates coordinate structures directly to plurals, and argues that a consequence of the proposed LF is that all natural language conjunction and disjunction is group forming rather than propositional. All semantic ambiguities between distributed and collective coordination can then be derived with the appropriate logical representation for plurals in general, rather than having a separate semantics altogether for coordination.Item Learning Newton's Second Law Using a Microcomputer Based Laboratory Curriculum(1995) Morse, Robert Alan; Layman, John W.; Education; Digital Repository at the University of Maryland; University of Maryland (College Park, MD)This study investigated the effect of theory-based Microcomputer Based Laboratory instruction on high school students' understanding of Newton's second law in a high school physics course taught by the teacher-researcher. The study focused on 1) the effect of the theory-based MBL instructional design on student understanding of Newton's second law, 2) on the changes in conceptual understanding that occurred, and 3) on the effect of student learning beliefs on conceptual change. Data sources included pretest and posttest measures of conceptual understanding, audiotape debriefings of students during a seven day unit, and pretest and posttest measures of students' motivational and self-regulated learning beliefs. The design of the instructional unit was based on prior research and theory. It is important to specify the characteristics as well as the content of the knowledge we would like students to construct. Desirable characteristics of physics knowledge are that it be accurate, extendable, integrated with other knowledge, recognized as knowledge, related to experience and experiment, strategic, and available in multiple representations including verbal, graphical, algebraic, pictorial, and story representations. Proponents argue that appropriately designed Microcomputer Based Laboratory instruction can promote construction of such knowledge. The theory-based instructional unit employed real-time computer graphing of force and motion variables in a novel "iconographic" experiment which enabled students to determine the relationship between force and motion variables by simple recognition. The study found that the nature of students' conceptual change was consistent with the mechanisms postulated for MBL instruction, that the short chain of reasoning in the iconographic force and motion experiment allowed students to readily identify and focus on the goals of the experiment rather than be distracted by a profusion of sub-goals, that this instruction is more effective than some traditional instruction and as effective as some other theory-based instruction in Newton's second law, based on Force Concept Inventory (Hestenes, Wells, & Swackhamer, 1992) and Force and Motion Concept test (Thornton, 1992a) scores. The study failed to achieve the goal of relating motivational, cognitive and performance measures using the Motivated Strategies for Learning Questionnaire (Pintrich & DeGroot, 1990).Item MOLECULAR ANALYSIS OF CYCLOPHILIN FUNCTION IN THE YEAST SACCHAROMYCES CEREVISIAE(1994) Davis, Edward S.; Brennan, Miles S.; Digital Repository at the University of Maryland; University of Maryland (College Park, MD)The cyclophilins are a family of proteins first identified as receptors for cyclosporin A (CsA), a cyclic peptide of fungal origin. CsA inhibits T-lymphocyte activation, and is thus a potent immunosuppressant. Although cyclophilins are ubiquitous, and highly conserved, among eukaryotes, their normal physiological functions are unknown. As the receptors for CsA, cyclophilins might be involved in regulating signal transduction pathways. Cyclophilns also have peptidyl-prolyl, cis-trans isomerase (PPIase) activity in vitro, suggesting a role in protein folding in vivo. While CsA inhibits cyclophilin's PPIase activity, this inhibition is insufficient to account for the pharmacological activity of CsA. Therefore, previous results cannot be readily synthesized into a model for cyclophilin function. The goal of this project was to define and characterize physiological roles of cyclophilins using the yeast S. cerevisiae. Three S. cerevisiae cyclophilin genes were cloned and inactivated by insertional mutagenesis. I demonstrated that one, CPR3, is necessary for the efficient metabolism of non-fermentable carbon sources. The CPR] gene product, Cpr3, is localized to the mitochondrial matrix, and a truncated version of Cpr3 expressed in bacteria binds CsA. CPR3 inactivation does not significantly compromise the induction of transcription of two nuclear cytochrome genes. Thus, Cpr3 is not necessary for the signal transduction pathway governing cytochrome gene expression. To identify biochemical targets of Cpr3, I demonstrated that inactivation of a mitochondrial lactate dehydrogenase is insufficient to account for the growth defect of cpr3 mutants. An exhaustive search for high-copy suppressors of the growth defect of cpr3 mutants led to the identification of a novel gene, JEN1, that suppresses the growth defect at elevated temperature. JEN1 encodes a protein that is probably a lactate transporter, and thus not a direct biochemical target of Cpr3. A dominant mutation in a nuclear gene, JEN2, suppresses the growth defect of cpr3 mutants on lactate at 30°C and 37°C. JEN2 might encode a direct biochemical target of Cpr3. In summary, the cyclophilin, Cpr3, plays a general role in the efficient function of yeast mitochondria, and presents an excellent model system for studying cyclophilin function.
