A case study: the development of Stephanie's algebraic reasoning
No full textThis research provides an analysis of the mathematical growth and development of one student, Stephanie, as she worked on early algebra tasks during her eighth-grade year as part of a teaching experiment. Stephanie was among the original participants in a longitudinal study which investigated how students develop mathematical ideas under conditions that fostered independent exploration, reasoning, and justification of ideas (Maher, 2005). A qualitative approach based on the analytical model described by Powell, Francisco, and Maher (2003), was taken in analyzing videotape data from the Robert B. Davis Institute of Learning archive, along with student work. Seven task-based interview sessions were analyzed, spanning a six month period, beginning from November 8, 1995 to April 17, 1996. The research focused on Stephanie’s algebraic reasoning; in particular, how she built an understanding of the binomial theorem and related it to Pascal’s triangle. Stephanie’s representations, her explanations and justifications, and her methods of dealing with obstacles to understanding, were all examined and provided the basis for this research. The analysis shows that Stephanie built her mathematical understanding through the development of multiple representations of concepts and moved fluidly between and among the representations that she organized into ‘symbolic’ and ‘visual’ representations. Symbolic representations included algebraic expressions, combinatorics notation, and Pascal’s triangle while visual representations included drawings, tables, models formed by algebra blocks and other manipulatives, and towers built with unifix cubes. Furthermore, through Stephanie’s explanations and justification of her representations and reasoning in general, she invented strategies to convince herself as well as the researchers that she had fulfilled the requirements of the problem task. When dealing with obstacles to her understanding such as lack of information, or calculating obstacles, Stephanie acquired the use of several heuristic methods in order to overcome them. These included the use of substituting in numbers in order to test a conjecture; returning to basic meaning; drawing diagrams; building models; and considering a simpler problem. Throughout the task-based interviews, Stephanie retrieved knowledge from her earlier problem solving and extended this knowledge to build new ideas, while tackling more challenging problems. In particular, Stephanie mapped the coefficients in the binomial expansion to particular rows in Pascal’s Triangle; she connected these ideas to her problem solving from earlier work in the elementary grades. The findings are relevant to the timing and method of early algebraic instruction in schools.Ed.D.Includes bibliographical referencesby Eman Y. Aboelnag
Dietary adequacy of Egyptian children with autism spectrum disorder compared to healthy developing children
No full textAlthough the etiology and pathology of autism spectrum disorder (ASD) is still poorly understood, a number of environmental, anthropological, neurobiological and genetic factors have been related to the pathophysiology of ASD, even the impact of oxidative stress response related to the environment and nutrition intake. Usual recommended dietary habits are based on the combination of behavioral and dietary or nutraceutical interventions together with pharmacotherapy. Investigations about a reliable relationship between diet and ASD are still lacking. The present study aimed at comparing dietary regimens and habits of normally developing apparently healthy children, without diagnosed ASD, with a pediatric population of individuals affected by autistic disorder. Assessments of nutritional and anthropometric data, in addition to biochemical evaluation for nutrient deficiencies, were performed. A total of 80 children with autistic disorder and 80 healthy, normally developing pediatric individuals were enrolled in the study. Parents were asked to complete the standardized questionnaire regarding the different types of food and the proportion of a serving for their children. Biochemical analysis of micro- and macronutrients were also done. Plotting on the Egyptian sex-specific anthropometric growth (auximetric) chart, absolute weights as well as weight-related for age classes, were significantly higher in cases than healthy controls. No differences between groups were observed in regard to total kilocalories (kcal), carbohydrates, and fat intake. A total of 23.8% of children with autistic disorder vs. 11.3% in the healthy control group had a nutrient intake with features below the Recommended Dietary Allowance (RDA) of protein. Children with autistic disorder showed low dietary intake of some micronutrients; calcium (Ca), magnesium (Mg), iron (Fe), selenium (Se) and sodium (Na), also they had significantly high intake of potassium (K) and vitamin C compared to healthy controls. Serum Mg, Fe, Ca, folate and vitamin B12 in children with autistic disorder were significantly low compared with healthy children. Significant positive correlations between serum Mg, Fe, Ca, vitamin B12 and folate and their levels in food were present. These results confirmed that different nutritional inadequacy was observed in Egyptian children with autistic disorder. The evidence reported in the present study should recommend screening of the nutritional status of ASD children for nutrient adequacy to reduce these deficiencies by dietary means or by administering appropriate vitamin and mineral supplements. Nutritional intervention plan should be tailored to address specific needs

The principle of non-refoulement under the European Convention on Human Rights and the United Nations Convention Against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment /
No full textIn this study, Eman Hamdan examines the protection against refoulement under the European Convention on Human Rights and the UN Convention against Torture, with the aim to determine which of those Conventions affords better protection for international protection seekers. Hamdan explores the scope and content of the principle of non-refoulement under both Conventions and the application of the principle to the immigration control measures and the extraordinary rendition operations. The author provides a comprehensive and comparative analysis of the case-law of both the European Court of Human Rights and the UN Committee against Torture on the procedural and substantive aspects of the principle of non-refoulement, in order to help practitioners to determine which of these human rights treaty bodies is more favorable for their specific non-refoulement case. This book was chosen to participate in the Professor Walther Hug Prize 2014-2015, which is a prize for the best legal researches in Switzerland for each academic year
Isolation and identification of oil degrading bacteria from oil contaminated soil, 2015
No full textOil spills are a universal threat impacting local, national and world communities alike. Bioremediation that is natural, efficient, economical and safe is the best solution for protecting the environment from oil related damages. In this study, motor oil degrading bacteria were isolated from oil-contaminated soil samples from a suburban Atlanta, Georgia community. Mineral salt broth containing 1 Ow-40 motor oil as the sole carbon source was used to isolate motor oil degrading bacteria. Motor oil tolerant and metabolizing bacteria were identified using morphological and biochemical tests. Two bacterial isolates were then tested for their tolerance varying concentrations of diesel and kerosene oils for comparison with motor oil consumption. Observed results suggest that the isolated bacteria from oil contaminated soil possess abilities to metabolize motor oil, kerosene and diesel. Knowledge of the tolerance ranges of the isolated bacteria can indicate their potential to be of use in the remediation of terrestrial petroleum oil spills in a manner that is natural, economical, quick and efficient
Nations without nationalisms: on Palestinian and American Indian literary imaginations
No full text“Nations without Nationalisms: On Palestinian and American Indian Literary Imaginations” approaches settler colonialism as a story that exhibits complex identity politics, competing concepts of humanity, and overlapping narratives of diaspora and trauma. It is also a story that is constantly disputed by Indigenous presence and decolonial and international movements of resistance. I explore indigeneity as a category of identification to better understand forced and voluntary migrations and what constitutes the concepts of settler, refugee, and migrant in the United States and Israel. Building on an interpretive framework that situates Indigenous theory alongside Palestine studies, my dissertation has two major arguments. First, I critique settler nationalism and approach the United States and Israel as exhibiting a discursive allegiance to each other and, more broadly, to European principles of nationhood. I develop this analysis by drawing a transnational web of literary exchanges in the nineteenth century that includes Emma Lazarus, George Eliot, Mordecai Noah, Theodor Herzl, and Israel Zangwill. Second, I argue that Indigenous nations, as land-based collectives that have functioned without statehood, intervene in popular assumptions that the nation-state is the only form of legitimate belonging. Here, I analyze expressions of indigeneity in Palestinian and American Indian writings towards conceptualizing “Indigenous literature” as a global literary genre with shared literary patterns and significant political interventions. Approaching this genre comparatively, I analyze representations of being, land, and political movement as an Indigenous literary modulation of character, setting, and plot, and as they unfold in the writings of Mahmoud Darwish, Samih Al-Qasim, Suheir Hammad, Steven Salaita, Leanne Simpson, and LeAnne Howe. As it exists today, U.S. scholarship can benefit from incorporating a global narrativization of indigeneity and ongoing colonialisms and attending more closely to their cultural nuances. Furthermore, learning from Palestine as a microcosmic example of modern-day settlement, exile, and ethnic conflict can help us understand the precarious relationship between displacement and nationalism in the U.S. and in many other parts of the world.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2022-08-01The student, Eman Ghanayem, accepted the attached license on 2020-07-10 at 02:25.The student, Eman Ghanayem, submitted this Dissertation for approval on 2020-07-10 at 02:58.This Dissertation was approved for publication on 2020-07-10 at 15:53.DSpace SAF Submission Ingestion Package generated from Vireo submission #15556 on 2020-10-02 at 15:50:12Made available in DSpace on 2020-10-07T22:49:51Z (GMT).

Comparative Analysis of Japanese Folklore Ama No Hagoromo and Indonesian Folklore Jaka Tarub
No full textThis research focuses on the Comparative Analysis of Japanese Folklore Ama No Hagoromo and Indonesian Folklore Jaka Tarub. The author chose this title because the author is interested in Japanese folktales Ama No Hagoromo and Jaka Tarub which are two folktales that come from different countries, but have almost the same story structure. These two folktales have a similar theme, which tells the main character who is an ordinary young man, but gets a wife who is an angel from heaven. In the end, the young man had to lose his wife because his lie was known by his wife. This research method uses a qualitative method with a structural approach to find out the similarities and differences in themes, characters, settings, plot, and mandate contained in the two folktales. After conducting the analysis, the author will compare the intrinsic elements of the two stories using the comparative literature method. The results of this study show that there are similarities in the theme, namely both have a major theme, namely love at first sight and the minor theme is crime (stealing), in the characters, namely both have main characters and additional characters, in the plot, namely both have a forward plot, in the setting, namely both have a place setting and time setting, and in the mandate, namely both the message conveyed must be honest. The basic differences in the two folktales to be compared in local wisdom are in the Ama No Hagoromo folktale the angels who appear are eight while in the Jaaka Taarub folktale the angels who appear are seven, in the Ama No Hagoromo folktale the angel's shawl is white while in the Jaka Tarub folktale the angel's shawl is red. The conclusion of this research is that folktales are not only used as entertainment and are only seen as oral traditions of children's bedtime. However, it can try to understand the positive values obtained as learning in everyday life.127 PagesSkripsi Sarjan
Analysis of Amae's Behavior Reflected in the Characters of Mikage and Yuichi in the Novel "Kitchen" Works Yoshimoto Banana
No full textJapan has a unique culture called "Amae" which describes the behavior of a person's dependence on others for attention and affection. This concept is explored in the novel "Kitchen" by Yoshimoto Banana. The research theory used is the moral approach and sociological aspects in the novel. In this research, the author specializes in describing amae behavior as reflected in the characters Mikage and Yuichi in the novel Kitchen and describes the lives of Mikage and Yuichi with the concept of amae. The results of the research show that amae's behavior is reflected in the characters Mikage and Yuichi and explains the lives of the characters Mikage and Yuichi with the concept of amae used by the author in the novel "Kitchen" through three sub-concepts, namely kuyami (feeling regret), toriiru (attracting attention), and tanomu (relying on oneself). These concepts show that good relationships can provide motivation and survival for the characters Mikage and Yuichi. In the novel, the concept of amae is a real example of how Japanese society interacts, influences and relates to its social environment.48 pagesSkripsi Sarjan
