The Importance of Students Engaging in Anti-Racism Education: A Case Study

While adults generally acknowledge that children are susceptible by what they see and hear in their social surrounds, many do not believe children can be shaped by racist discourse. Based on anti-racism learning outcomes achieved among two cohorts of 12-14-year-old Grade Eight students—the entirety of who initially held racist perspectives of Aboriginal Australians, this paper argues the need for schools to engage all students in anti-racism education

Increasing Empathy, Decreasing Prejudice: The Role Of Empathy In Challenging Prejudice Among Students

Is empathy a remedy for prejudice? This short paper argues it has a large role to play. It explores the authors’ observations as a Humanities teacher engaging Grade 8 Australian students between the ages of 12 and 14 in a study of the film Rabbit-Proof Fence. As students empathised with Aboriginal (Indigenous Australian) children forcibly removed from their families under Australian government policy in the twentieth century, they questioned the negative things they themselves had come to believe about Indigenous Australians

Understanding Teacher Leadership in Middle School Mathematics: A Collaborative Research Effort

We report findings from a collaborative research effort designed to examine how teachers act as leaders in their schools. We find that teachers educated by the Math in the Middle Institute act as key sources of advice for colleagues within their schools while drawing support from a network consisting of other teachers in the program and university-level advisors. In addition to reporting on our findings, we reflect on our research process, noting some of the practical challenges involved, as well as some of the benefits of collaboration

Haematological problems associated with Gaucher's disease

Five recent cases of Gaucher's disease seen at Groote Schuur Hospital illustrate the haematological complications. The main problem is hypersplenism with secondary thrombocytopenia. Two patients underwent splenectomy for this reason, and one gained lasting improvement. None of the more rare haematological problems was seen in this series.S. Afr. Med. J., 48, 1300 (1974)

Profile, Plan and Section: Three Developments for Sea-Bed Survey

The purpose of this article is to offer a response to some of the requirements, indicated in previous contributions, in underwater measurement and detection. The instruments described here were demonstrated to delegates during the International Hydrographic Conference in April 1967. Most of the accompanying records were taken during the course of the Conference

Nivolumab-induced fulminant diabetic ketoacidosis followed by thyroiditis

Five days following the 3rd cycle of nivolumab, a monoclonal antibody, which acts as immune checkpoint inhibitor against the programmed cell death protein-1, for metastatic lung adenocarcinoma, a 56-year-old woman presented at the hospital critically ill. On admission, she had severe diabetic ketoacidosis (DKA), as evidenced by venous glucose of 47 mmol/L, blood ketones of 7.5 mmol/L, pH of 6.95 and bicarbonate of 6.6 mmol/L. She has had no personal or family history of diabetes mellitus (DM), while random venous glucose, measured 1 week prior to hospitalisation, was 6.1 mmol/L. On admission, her HbA1c was 8.2% and anti-GAD antibodies were 12 kIU/L (0–5 kU/L), while islet cell antibodies and serum C-peptide were undetectable. Nivolumab was recommenced without the development of other immune-mediated phenomena until 6 months later, when she developed hypothyroidism with TSH 18 U/L and low free T4. She remains insulin dependent and has required levothyroxine replacement, while she has maintained good radiological and clinical response to immunotherapy. This case is notable for the rapidity of onset and profound nature of DKA at presentation, which occurred two months following commencement of immunotherapy. Despite the association of nivolumab with immune-mediated endocrinopathies, only a very small number of patients developing type 1 DM has been reported to date. Patients should be closely monitored for hyperglycaemia and thyroid dysfunction prior to and periodically during immunotherapy

Optimized Effective Potentials in Finite Basis Sets

The finite basis optimized effective potential (OEP) method within density functional theory is examined as an ill-posed problem. It is shown that the generation of nonphysical potentials is a controllable manifestation of the use of unbalanced, and thus unsuitable, basis sets. A modified functional incorporating a regularizing smoothness measure of the OEP is introduced. This provides a condition on balanced basis sets for the potential, as well as a method to determine the most appropriate OEP potential and energy from calculations performed with any finite basis set.Comment: 23 pages, 28 figure

A retrospective study of anxiety disorder diagnoses in the military from 2000 to 2009

The objective of this study was to describe trends in the diagnostic rates for anxiety disorders (ADs) types in the U.S. military from 2000 to 2009. Data for the numbers of diagnosed cases for the first documented occurrence of ADs during ambulatory visits while serving in the military were obtained from the Defense Medical Epidemiology Database for all active duty service members and examined across branch of service and by gender. Results indicate that Anxiety Not Otherwise Specified (ANOS) was the most frequently diagnosed AD type in each of the 10 years between 2000 and 2009, with an average rate of 0.8 per 100 service members for first service occurrence, followed by PTSD at a rate of 0.5 out of every 100. Starting in 2002, the yearly first occurrence rates of ANOS and PTSD were significantly higher (p \u3c 0.001) compared to each proceeding year, with the same pattern present among males and females separately. The majority of first occurrence AD diagnoses were diagnosed in the Army (47% of Anxiety NOS and 60% of PTSD cases) compared to the other service branches (i.e., Navy, Air Force, and Marines)

Validation of electron density profiles derived from oblique ionograms over the United Kingdom

Inversion algorithms are available to derive the vertical electron density profile at the midpoint of an oblique sounder path. The techniques open up the possibility of monitoring the ionosphere at otherwise inaccessible locations, such as over sea or inhospitable terrain. A new method of monitoring the ionosphere based on radio tomography can be used to create two-dimensional images of electron density. The results in this paper compare midpoint profiles derived from oblique ionograms with corresponding profiles obtained from tomographic images of electron density and from a vertical ionospheric sounder. The comparisons illustrate the oblique sounder inversion technique and its inherent limitations. The results provide useful information on the complementary nature of the separate ionospheric measurement techniques and have implications for the use of these measurements as inputs to real-time ionospheric models

Infrastructure Redesign and Instructional Reform in Mathematics: Formal Structure and Teacher Leadership

Designing infrastructures to support instruction remains a challenge in educational reform. This article reports on a study of one school system\u27s efforts to redesign its infrastructure for mathematics instruction by promoting teacher leadership. Using social network and interview data from 12 elementary schools, we explore how the district\u27s infrastructure redesign efforts were internally coherent with and built upon existing infrastructure components. We then explore relations between infrastructure and school practice as captured in the instructional advice- and information-seeking interactions among school staff, finding that teacher leaders emerged as central actors and brokers of advice and information about mathematics within and between schools. Further, changes in school advice and information networks were associated with shifts in teachers\u27 beliefs about and practices in mathematics toward inquiry-oriented approaches consistent with district curriculum. We argue that the district\u27s redesign efforts to support teacher leadership coupled district curriculum and school and classroom practice in mathematics
