Examining the Role of Ethnic Identity in the Relationship Between Characteristics of Autism Spectrum Disorders and Eating Disorders

The present work provides a synthetic literature review investigating the potential role of ethnic identity in the relationship between Autism Spectrum Disorders (ASD) and eating disorders (EDs). To date, there is no literature that directly examines the role that ethnic identity may play in the relationship between these two disorders. However, there is reason to believe it may; previous literature has shown that race/ethnicity plays a role in both of these disorders, and the role of ethnic identity has been more fully explored in the ED population. Notably, there is little research that examines the role of ethnic identity on ASD diagnoses. Based on the literature addressing the roles of race/ethnicity and ethnic identity in EDs along with the role of race/ethnicity in ASD, a hypothesis was formulated and explored in an attempt to facilitate an understanding of the role that ethnic identity has on the relationship between EDs and ASD. The thesis concludes by highlighting implications for clinical practice and offering suggestions for future research

Algo de lo nuevo en la conducta empresarial

Después de los dos momentos en que los empresarios mexicanos entraron en abierta confrontación con el grupo gobernante -los últimos años del sexenio de Luis Echeverría y al producirse la nacionalización bancaria-, éstos parecen haber definido una conducta de amplia independencia y de articulación clasista, que lo mismo les permite apoyar que criticar las medidas gubernamentales y que, principalmente, les ha permitido una mayor influencia directa en la conducción del país. A través de la politización de mecanismos antes exclusivamente económicos, los capitalistas no sólo han dejado constancia de su fuerza, sino que han hecho un uso de ella sumamente costoso para el país

Geometric Constructions from an Algebraic Perspective

Many topics that mathematicians study at times seem so unrelated such as Geometry and Abstract Algebra. These two branches of math would seem unrelated at first glance. I will try to bridge Geometry and Abstract Algebra just a bit with the following topics. We can be sure that after we construct our basic parallel and perpendicular lines, bisected angles, regular polygons, and other basic geometric figures, we are actually constructing what in geometry is simply stated and accepted, because it will be proven using abstract algebra. Also we will look at many classic problems in Geometry that are not possible with only straightedge and compass but need a marked ruler

Política de la gran burguesía en México frente a la crisis

Al sobrevenir las primeras adversidades serias, fundamentalmente debido a la crisis económica, la gran burguesía mexicana ve ahora la necesidad de intervenir directamente en campos en los que antes no lo hacía, despliega un programa político; exige el repliegue estatal del ámbito económico; desarrolla una gran empresa ideológica; exige una nueva forma de gobernar y no acepta más la subordinación política a la burocracia estatal

Testing Multiple Climate Stressors at the Cold Range Limit of a Marine Calcifier

Coastal marine ecosystems have been identified as at particularly high risk from global climate change. Laboratory mesocosm experiments with model organisms can be useful in elucidating the effects of multiple climate change stressors on marine species. Here I examine the combined effects of marine heatwaves (MHWs) and ocean acidification (OA) on early embryonic development of the sea urchin Arbacia punctulata taken from its cold (northern) range limit in the Northwest Atlantic. I observed additive effects of MHWs and OA on developmental rates, with rates enhanced by MHWs and hindered by OA as compared to ambient conditions. Hence, MHWs mitigated a negative effect of OA on development of the species at its cold range limit. My results provide an improved understanding of how MHWs and OA can combine to affect the sensitive early life-history stages of calcifying marine invertebrates and may be useful in predicting future shifts in species distributions

Las acciones de la banca. Conservar lo importante

¿Cuáles y cuántas son las acciones no bancarias de la banca? ¿Qué implicaría que el gobierno las integrara dentro de una política del sector paraestatal? ¿Qué significado tendría que dichos títulos se vendieran? Sería difícil creer que en los últimos años la banca privada disminuyó sus controles en la industria, el comercio y los servicios. Al parecer, la solución de este enigma está en la segunda lista, que comprende 129 empresas, de las cuales una de ellas es el propio Banco de México, ahora nacionalizado en su serie B que estaba en poder de los bancos privados; otra más es Telmex. Otras 35 son bancos, en algunos de los cuales la participación es mayoritaria como producto de absorciones o fusiones en proceso. Salta a la vista que la banca nacional tiene una importante participación industrial, cuyo futuro no puede resolverse de manera aventurada

SMART Moves in Math: Unveiling Student and Teacher Perceptions on SMART Goal Setting in Second-Grade Math Instruction

Goal setting is a growing strategy in education and has been shown to improve task performance. Studies that have focused on the effects of goal-setting in the past have highlighted both positive perceptions from students and an increase in academic performance. This study investigated student and teacher perceptions of the integration of SMART goals in second-grade math instruction as well as the perceived effects of SMART goals. The researcher collected data through observational field notes, a survey at the end of the study, student artifacts and interviews. The researcher analyzed the data using the constant comparative method. The resulting secondary codes were positive effects and success, student agency and perseverance, and mixed feelings and future changes. Findings suggest that students varied in their perceptions of SMART goals. Beyond the students’ perceptions were findings of an increase in literacy, motivation, and a need for more teacher feedback

Microswimmer-driven agglutination assay

Lab-on-a-chip systems for point-of-care testing demonstrate a promising development towards more accurate diagnostic tests that are of extreme importance for the future global health. This work presents an agglutination assay performed in micrometer sized well using Janus PS/Ag/AgCl micromotors to enhance the interactions between goat anti-human IgM functionalized particles and Human IgM. The fabricated microwell chips are a suitable platform to analyze the interaction between different particles and to perform the agglutination assays. The interaction between active Janus particles and passive and functionalized particles is studied, as well as the influence of ions on the motion of the Janus particles. Agglutination assays are performed with and without the presence of Janus particles, and in different PBS concentrations. Once illuminated with blue light, passive SiO2 particles were effectively excluded from Janus particles, while SiO2 NH2 particles revealed attraction. In contrast, functionalized SiO2 NH2 Ab particles suspended in PBS did not show any interaction. It was found that the optimal working conditions for antibodies and Janus particles differed and, as a result, the Janus particles did not reveal a desirable interaction between the functionalized particles and IgM. Further experiments should be performed to find the proper conditions in which the antibodies and the Janus particles maintain their activities. It is believed that an effective interaction between the functionalized and Janus particles could be achieved by modifying the parameters that affect their interaction such as the zeta potential and the medium in which the assay is being performed. This preliminary work provides the first steps towards the development of a fully integrated lab on a chip system for point of care testing.:Abstract ........................................................................................................................ iii Acknowledgments.......................................................................................................... v Table of Contents .......................................................................................................... vi List of Tables ............................................................................................................. viii List of Figures ............................................................................................................... ix Abbreviations ................................................................................................................. x 1.
