Learning by Seeing by Doing: Arithmetic Word Problems

Learning by doing in pursuit of real-world goals has received much attention from education researchers but has been unevenly supported by mathematics education software at the elementary level, particularly as it involves arithmetic word problems. In this article, we give examples of doing-oriented tools that might promote children\u27s ability to see significant abstract structures in mathematical situations. The reflection necessary for such seeing is motivated by activities and contexts that emphasize affective and social aspects. Natural language, as a representation already familiar to children, is key in these activities, both as a means of mathematical expression and as a link between situations and various abstract representations. These tools support children\u27s ownership of a mathematical problem and its expression; remote sharing of problems and data; software interpretation of children\u27s own word problems; play with dynamically linked representations with attention to children\u27s prior connections; and systematic problem variation based on empirically determined level of difficulty

Wages, Benefits, Hours, Commuting Time, and License Renewal for Iowa Registered Nurses

The Iowa Board of Nursing licensing database for Registered Nurses (RNs) contains information on Registered Nurses who have renewed their licenses including age, race, gender, education, and location of employment.  It also contains comparable information on nurses who opted not to renew at the time of their last renewal. This report contains an analysis of the nurses’ characteristics that increase the likelihood of license renewal based on all useable information contained in the licensing database.  In addition, we randomly sampled subpopulations of nurses who had current licenses and nurses who had allowed their licenses to expire.  A survey of these nurses was analyzed to provide insights into the effects of individual wages, benefits, family income, family responsibilities, hours worked, and commuting time on the decision to work, work in nursing, and maintain a nursing license. Wages; workforce; benefits; labor force; nurses; health care

Translating Autoimmune Pathogenesis into Targeted Therapies for Systemic Sclerosis

Targeted therapies including tumour necrosis factor α (TNFα) inhibitors have transformed the management of a number of autoimmune conditions over the past 20 years. One autoimmune rheumatological condition with significant potential for the development of targeted therapies is systemic sclerosis (SSc). In this chapter, we use SSc as an example of how research into the pathogenic processes underlying autoimmune conditions can be translated into novel targeted therapies. We review the evidence base for a range of targeted therapies for SSc identified from a systematic literature search, before highlighting a number of studies currently underway

Biomarkers of Pediatric Brain Tumors

Background and Need for Novel Biomarkers: Brain tumors are the leading cause of death by solid tumors in children. Although improvements have been made in their radiological detection and treatment, our capacity to promptly diagnose pediatric brain tumors in their early stages remains limited. This contrasts several other cancers where serum biomarkers such as cancer antigen (CA) 19-9 and CA 125 facilitate early diagnosis and treatment. Aim: The aim of this article is to review the latest literature and highlight biomarkers which may be of clinical use in the common types of primary pediatric brain tumor. Methods: A PubMed search was performed to identify studies reporting biomarkers in the bodily fluids of pediatric patients with brain tumors. Details regarding the sample type [serum, cerebrospinal fluid (CSF), or urine], biomarkers analyzed, methodology, tumor type, and statistical significance were recorded. Results: A total of 12 manuscripts reporting 19 biomarkers in 367 patients vs. 397 controls were identified in the literature. Of the 19 biomarkers identified, 12 were isolated from CSF, 2 from serum, 3 from urine, and 2 from multiple bodily fluids. All but one study reported statistically significant differences in biomarker expression between patient and control groups. Conclusion: This review identifies a panel of novel biomarkers for pediatric brain tumors. It provides a platform for the further studies necessary to validate these biomarkers and, in addition, highlights several techniques through which new biomarkers can be discovered
