Resilient and Nonresilient Hispanic English Language Learners' Attitudes Toward Their Classroom Learning Environment in Mathematics     

Héctor H. Rivera  Hersh C. Waxman 《Journal of Education for Students Placed at Risk》2013,18(3):185-200

This study examines resilient and nonresilient characteristics in mathematics among Hispanic students in a major metropolitan city located in the south central region of the United States. The study examined data from semistructure interviews of 118 resilient and nonresilient English language learners (ELLs) in 4th and 5th grade. The interviews focused on a variety of factors including: (a) individual attributes (e.g., students’ motivation); (b) school and classroom factors (e.g., satisfaction, involvement, and affiliation); (c) family factors (e.g., parent involvement in academics); and (d) students’ use of time (e.g., doing homework). Additional indicators that were examined include help-seeking behaviors and skills that allow students to cope with academic difficulties. Overall, the findings indicate significant differences between resilient and nonresilient students on academic performance and their self-efficacy on perceived mathematical abilities. Significant differences were also found in the home learning environment, indicating that resilient students receive more assistance at home on academic tasks than non-resilient students.  相似文献   

Sickle Cell Trait Presenting as Chronic Calcific Pancreatitis with Pseudocyst- A Case Report

Sickle cell disease is known to cause acute pancreatitis either due to gall stones obstructing the pancreatic duct or by vaso-occlusive mechanism. However chronic pancreatitis is a very rare complication in sickle cell anemia. We report a case of sickle cell trait presenting with chronic pancreatitis with pseudo cyst. USG abdomen and CT abdomen confirmed the diagnosis of chronic calcific pancreatitis with pseudocyst. Etiological work up for other causes did not reveal anything except sickle cell trait. This case represents a rare association between chronic calcific pancreatitis and sickle cell trait.  相似文献   

Individual differences: Either relational learning or item-specific learning in a same/different task     

L. Caitlin Elmore  Anthony A. Wright  Jacquelyne J. Rivera  Jeffrey S. Katz 《Learning & behavior》2009,37(2):204-213

Three pigeons were trained in a three-item simultaneous same/different task. Three of six stimulus combinations were not trained (untrained set) and were tested later. Following acquisition, the subjects were tested with novel stimuli, the untrained set, training-stimulus inversions, and object shape and color manipulations. There was no novel-stimulus transfer—that is, no abstract-concept learning. Two pigeons showed partial transfer to untrained pairs and good transfer to stimulus inversions, suggesting that they had learned the relationship between the stimuli. Lack of transfer by the third pigeon suggests item-specific learning. The somewhat surprising finding of relational learning by 2 pigeons with only six training pairs suggests restricted-domain relational learning that was controlled more by color than by shape features. Individual differences of item-specific learning by 1 pigeon and relational learning by 2 others demonstrate that this task can be learned in different ways and that relational learning can occur in the absence of novel-stimulus transfer.  相似文献   

Mutation Analyses in Selected Exons of the MUT Gene in Indian Patients with Methylmalonic Acidemia     

Chandrawati Kumari  Seema Kapoor  Bijo Varughese  Sunil Kumar Pollipali  Siddarth Ramji 《Indian journal of clinical biochemistry : IJCB》2017,32(3):266-274

Deficiency or diminished activity of a cobalamin dependent enzyme methylmalonyl-CoA mutase causes inborn error of metabolism called methylmalonic acidemia (MMA). In this study we elucidated the spectrum of mutations in 21 Indian mut MMA patients by direct sequencing. Sequence analysis identified a total of 70 mutations in exon 2, 9, 11 and 12 of MUT gene. Out of which 26 mutations were predicted to be deleterious and rest were benign. The 23 novel mutations consist of four nonsense mutations (p.N6*, p.G539*, p.E609* and p.I671*), twelve missense mutations (p.K128I, p.N547T, p.D554Y, p.A558T, p.R559P, p.A631T, p.I647T, p.E656D, p.V657E, p.Q660H, p.K679N, and p.G696Y) and seven frame shift mutations (c.375_376insA, c.1642delA, c.1655delC, c.1825_1826insT, c.1957delGA, c.2014delA and c.2062_2063insGA). All of them are point mutations or micro rearrangements. Three of these mutations (p.K621N, p.G648D, p.G630E) have been previously reported; all of them are missense mutations. The mutations are distributed throughout the exon 2, 9, 11 and 12, 38.4 % mutation are located in exon 12.  相似文献

Apolipoprotein E4 polymorphism as risk factor for coronary heart disease among Indian subjects     

Tester F. Ashavaid  Seema P. Todur  Kappiareth G. Nair 《Indian journal of clinical biochemistry : IJCB》2002,17(1):83-93

Apolipoprotein E genotypes and lipid and lipoprotein levels were determined in hypercholesterolemic and angiographically vertified CHD subjects and compared against 90 normolipidemic controls. The ε4 allele was significantly prevalent in the hypercholesterolemic and CHD subjects. Significant increase in total cholesterol levels in apo ε4 containing subjects were observed in the hypercholesterolemic and CHD group. The study suggests that the ε4 allele by influencing the lipid levels could act as a risk factor for CHD.  相似文献   

Burning a Candle in a Vessel, a Simple Experiment with a Long History     

Francisco Vera  Rodrigo Rivera  César Nú?ez 《Science & Education》2011,20(9):881-893

The experiment in which a candle is burned inside an inverted vessel partially immersed in water has a history of more than 2,200 years, but even nowadays it is common that students and teachers relate the change in volume of the enclosed air to its oxygen content. Contrary to what many people think, Lavoisier concluded that any change in volume in this experiment is negligible; moreover, the explanation relating oxygen consumption in the air with its change in volume is known to be wrong. In this work we briefly review the history behind the candle experiment and its relationship with some typical erroneous explanations. One of the key factors behind Lavoisier’s success was the use of experiments carefully designed to test different hypotheses. Following these steps, we performed several closed volume experiments where the candle wick was replaced by a capillary stainless steel cylinder supported and heated by a nichrome filament connected to an external power supply. Our recorded experiments are displayed as web pages, designed with the purpose that the reader can easily visualize and analyze modern versions of Lavoisier’s experiments. These experiments clearly show an initial phase of complete combustion, followed by a phase of incomplete combustion with elemental carbon or soot rising to the top of the vessel, and a final phase where the hot artificial wick only evaporates a white steam of wax that cannot ignite because no oxygen is left in the closed atmosphere. After either a complete or incomplete combustion of the oxygen, our experiments show that the final gas volume is nearly equal to the initial air volume.  相似文献   

Oxidant-antioxidant status in colorectal cancer patients—Before and after treatment     

Sharmila Upadhya  Subramanya Upadhya  S. Krishna Mohan  K. Vanajakshamma  Mamatha Kunder  Seema Mathias 《Indian journal of clinical biochemistry : IJCB》2004,19(2):80-83

Erythrocyte antioxidant glutathione and malondialdehyde levels in erythrocytes and plasma glutathione S-transferase levels were estimated in patients with colorectal cancer and compared to controls. Further, the patients underwent four weeks of radiotherapy with adjuvant chemotherapy. The same parameters were estimated after four weeks of radiotherapy and compared with pretreatment levels. It was observed that there was a decrease in erythrocyte glutathione and malondialdehyde levels in patients with colorectal cancer compared to controls, but not in case of GST. However, after chemoradiotherapy, there were no statistically significant differences in all the parameters studied.  相似文献   

Using food as a tool to teach science to 3 grade students in Appalachian Ohio     

Duffrin MW  Hovland J  Carraway-Stage V  McLeod S  Duffrin C  Phillips S  Rivera D  Saum D  Johanson G  Graham A  Lee T  Bosse M  Berryman D 《Journal of Food Science Education》2010,9(2):41-46

The Food, Math, and Science Teaching Enhancement Resource (FoodMASTER) Initiative is a compilation of programs aimed at using food as a tool to teach mathematics and science. In 2007-2008, a foods curriculum developed by professionals in nutrition and education was implemented in 10 3(rd)-grade classrooms in Appalachian Ohio; teachers in these classrooms implemented 45 hands-on foods activities that covered 10 food topics. Subjects included measurement; food safety; vegetables; fruits; milk and cheese; meat, poultry, and fish; eggs; fats; grains; and meal management. Students in four other classrooms served as the control group. Mainstream 3(rd)-grade students were targeted because of their receptiveness to the subject matter, science standards for upper elementary grades, and testing that the students would undergo in 4(th) grade. Teachers and students alike reported that the hands-on FoodMASTER curriculum experience was worthwhile and enjoyable. Our initial classroom observation indicated that the majority of students, girls and boys included, were very excited about the activities, became increasingly interested in the subject matter of food, and were able to conduct scientific observations.  相似文献
