Students reading aloud and reading silently for group work
Gavin Farrell 미래영어영문학회 2012 미래영어영문학회 학술대회 자료집 Vol.2012 No.12
For in-class group work assignments based on new texts teachers either have the students read the texts aloud to each other (taking turns, best readers, etc.), or have them read the texts silently before doing comprehension tasks, discussion questions, etc. A third, and less used technique, is to have the students read the text silently and then have someone read it aloud. This paper will explore the beliefs, observations, and outcomes of group student reading practices of a study conducted at Hankuk University of Foreign Studies for a course in newspaper editorial reading and writing. Each week various reading techniques were utilized. Students were surveyed on their experiences, and following weeks had slightly varying or repeated reading techniques. This paper will look at what students found to be effective group reading procedures. Sometimes a guide is wanted by students and sometimes fount of knowledge is wanted. This paper will expound the realpedagogik of what students need and want.

Objective: Lurasidone is an antipsychotic drug that shows a relative lack of weight gain common to many antipsychotics. Aripiprazole and ziprasidone also show little weight gain and can reduce olanzapine-induced food intake and weight gain in animals, paralleling some clinical findings. We hypothesized that lurasidone would have similar actions. Methods: Female Lister-hooded rats received intraperitoneal injection either 2× vehicle (saline), lurasidone (3 mg/kg) and vehicle, olanzapine (1 mg/kg) and vehicle, or olanzapine and lurasidone. Following drug administration food intake was measured for 60min. A further series of rats underwent a seven-day regime of once-daily administration of the above doses and free access to food and water. Weight gain over the course of the study was monitored. Results: Olanzapine induced a significant increase in food intake while lurasidone showed no significant effect. Co-administration of lurasidone with olanzapine suppressed the increase in food intake. Repeated dosing showed an increase in body weight after seven days with olanzapine, and no significant effect observed with lurasidone, while repeated administration of lurasidone with olanzapine reduced the effect of olanzapine on the increase in body weight. Conclusion: These findings support our hypotheses in that lurasidone, in addition to a lack of effect on acute food intake and short term weight gain, can reduce olanzapine-induced food intake and weight gain in rats. This indicates the drug to have an active anti-hyperphagic mechanism, rather than solely the absence of a drug-induced weight gain that is such a severe limitation of drugs such as olanzapine.
Pharmacogenetic Aspects of Antipsychotic Drug-induced Weight Gain - A Critical Review
Gavin P. Reynolds 대한정신약물학회 2012 CLINICAL PSYCHOPHARMACOLOGY AND NEUROSCIENCE Vol.10 No.2
Treatment with several antipsychotic drugs can result in weight gain, which may lead to further morbidity such as type 2 diabetes and cardiovascular disease via the development of metabolic syndrome. These important and problematic metabolic consequences of antipsychotic drug treatment probably reflect a pharmacological disruption of the mechanisms involved in control of food intake and body weight. The extent of weight gain following antipsychotic drug treatment shows substantial variability between individuals, due in part to genetic factors. Common functional polymorphisms in many candidate genes implicated in the control of body weight and various aspects of energy and lipid metabolism have been investigated for association with weight gain in subjects receiving antipsychotic drug treatment, and with metabolic pathology in chronic schizophrenia. Perhaps the strongest and most replicated findings are the associations with promoter polymorphisms in the 5-HT2C receptor and leptin genes, although many other possible genetic risk factors, including polymorphisms in the fat mass and obesity associated (FTO)gene and genes for the alpha2A adrenoceptor and melanocortin4 receptor, have been reported. Genome-wide association studies (GWAS) have also addressed antipsychotic-induced weight gain and other indicators of metabolic disturbances. However there is as yet little consistency between these studies or between GWAS and classical candidate gene approaches. Identifying common genetic factors associated with drug-induced weight gain and its metabolic consequences may provide opportunities for personalized medicine in the predictive assessment of metabolic risk as well as indicating underlying physiological mechanisms.
Localization of lung abnormalities on chest X-rays using self-supervised equivariant attention
Gavin D’Souza,N. V. Subba Reddy,K. N. Manjunath 대한의용생체공학회 2023 Biomedical Engineering Letters (BMEL) Vol.13 No.1
Chest X-Ray (CXR) images provide most anatomical details and the abnormalities on a 2D plane. Therefore, a 2D view of the 3D anatomy is sometimes sufficient for the initial diagnosis. However, close to fourteen commonly occurring diseases are sometimes difficult to identify by visually inspecting the images. Therefore, there is a drift toward developing computer-aided assistive systems to help radiologists. This paper proposes a deep learning model for the classification and localization of chest diseases by using image-level annotations. The model consists of a modified Resnet50 backbone for extracting feature corpus from the images, a classifier, and a pixel correlation module (PCM). During PCM training, the network is a weight-shared siamese architecture where the first branch applies the affine transform to the image before feeding to the network, while the second applies the same transform to the network output. The method was evaluated on CXR from the clinical center in the ratio of 70:20 for training and testing. The model was developed and tested using the cloud computing platform Google Colaboratory (NVidia Tesla P100 GPU, 16 GB of RAM). A radiologist subjectively validated the results. Our model trained with the configurations mentioned in this paper outperformed benchmark results.
Why We Still Need Multiculturalism: A Critical Review of Approaches to Cultural Accommodation
Gavin Hart 숙명여자대학교 아시아여성연구원 2020 OMNES: The Journal of Multicultural Society Vol.10 No.2
In the twenty first century we see an increasingly interconnected world with greater possibilities for the movement of people across national borders. Despite the rhetoric of nationalist politicians across the globe, migration will continue to be an important feature of contemporary societies in most of the advanced industrial economies. Furthermore, political questions related to sub-state nationalism remain an important part of the social landscape in many states. The question of how best to accommodate diversity has a significant history explored in a wide body of theoretical literature. Throughout the latter part of the twentieth century, the doctrine of multiculturalism became a common feature of approaches to diversity across the majority of liberal democratic states. More recently, multiculturalism has been the subject of a range of political and theoretical controversies. Critics suggest that this approach has the effect of dividing people into arbitrary categories, failing to promote real integration. This article contributes to this debate through carrying out a critical review of approaches to the accommodation of cultural diversity. It is argued that despite the appeal of other theoretical frameworks, that multiculturalism still represents the best all-round package to help us understand diversity and to accommodate difference in an equitable fashion.

The coercivity of a single 27 nm-spherical barium ferrite (S-BaFe) particle was simulated using three models: 1) Gibbs free energy (GFE), 2) Landau-Lifshitz-Gilbert (LLG), and 3) Stoner-Wohlfarth (S-W). Spherically and hexagonally shaped particles were used in the GFE and LLG simulations to investigate coercivity with the different shape anisotropies. The effect of shape was not included in the S-W model. It was found that the models using a spherical shape resulted in a coercivity higher than the models using the hexagonal shape with both shapes having the same diameter. The coercivity estimated with the S-W model was approximately the same as that for the spherical-shape models, which indicates that spherical shape has no significant effect on the particle’s coercivity at nanoscale.
