Students' perspectives on the nature of mathematics

This paper reports on one small component of a much larger study that explored the perspectives of students towards mathematics learning. Students were asked “What do you think maths is all about?” Some students responded in terms of mathematical content. Others commented on learning in general, or on problem-solving in particular. Some students talked about the usefulness of mathematics for everyday life. An overwhelming number of students answered the question by talking about the importance of mathematics for the future

Advancing Women, Changing Lives A Comprehensive Evaluation of the Gap Inc. P.A.C.E. Program

Globally the garment industry is one of the biggest employers of low-skilled women workers. Despite their large numbers in the workforce, relatively few female garment workers advance to higher-level positions as they have limited opportunities to acquire the skills that would enable their professional and personal growth. In response to this need, Gap Inc. initiated the P.A.C.E. (Personal Advancement & Career Enhancement) workplace education program to teach women the managerial, interpersonal, organizational and other practical skills needed to move forward in work and in life. This report summarizes findings from program evaluations conducted by ICRW from 2009 - 2013 at six factory sites where P.A.C.E. is implemented - two in India and one each in Cambodia, Vietnam, Bangladesh and China.Research findings from these robust, multi-country evaluations demonstrate that P.A.C.E. is an effective, sustainable and scalable model that yields high returns for women, their families and the businesses where they work

Probing the charged state of layered positive electrodes in sodium-ion batteries : reaction pathways, stability and opportunities

Sodium-ion batteries have received significant interest as a cheaper alternative to lithium-ion batteries and could be more viable for use in large scale energy storage systems. However, similarly to lithium-ion batteries, their performance remains limited by the positive electrode materials. Layered transition metal oxides, with chemical formula NaxMO2, have been extensively investigated and appear to show the most promise. However, the inability to reversibly extract large amounts of sodium ions from these layered structures, by charging to high voltages, has limited the useful capacity and cycle life of these materials. To address this, numerous studies have attempted to resolve the structural and chemical changes that take place in positive electrode materials upon cycling. This is particularly important at and near the charged state, which is where the materials\u27 structures are highly sodium deficient. Following a brief introduction into the status of sodium-ion battery positive electrodes, this work focuses on the development of knowledge and understanding into the structure of layered oxides at the charged state by highlighting cutting edge characterisation techniques that have been utilised. Finally, a perspective on future development is provided to direct further structural characterisation research which will enable the rational design of new and improved energy storage materials

Global School-Based Childhood Obesity Interventions: A Review

Background: The issue of childhood overweight and obesity has become a global public health crisis. School-based interventions have been developed and implemented to combat this growing concern. The purpose of this review is to compare and contrast U.S. and international school-based obesity prevention interventions and highlight efficacious strategies. Methods: A systematic literature review was conducted utilizing five relevant databases. Inclusion criteria were: (1) primary research; (2) overweight or obesity prevention interventions; (3) school-based; (4) studies published between 1 January 2002 through 31 December 2013; (5) published in the English language; (6) child-based interventions, which could include parents; and (7) studies that reported outcome data. Results: A total of 20 interventions met the inclusion criteria. Ten interventions each were implemented in the U.S. and internationally. International interventions only targeted elementary-aged students, were less likely to target low-income populations, and were less likely to be implemented for two or more years in duration. However, they were more likely to integrate an environmental component when compared to U.S. interventions. Discussion: Interventions implemented in the U.S. and internationally resulted in successful outcomes, including positive changes in student BMI. Yet, varying approaches were used to achieve success, reinforcing the fact that a one-size-fits-all approach is not necessary to impact childhood obesity. However, building on successful interventions, future school-based obesity prevention interventions should integrate culturally specific intervention strategies, aim to incorporate an environmental component, and include parents whenever possible. Consideration should be given to the potential impact of long-term, frequent dosage interventions, and subsequent follow-up should be given attention to determine long-term efficacy

A systematic review of emerging information technologies for sustainable data-centric health-care

© 2021 Elsevier B.V. Background: Of the Sustainable Development Goals (SDGs), the third presents the opportunity for a predictive universal digital healthcare ecosystem, capable of informing early warning, assisting in risk reduction and guiding management of national and global health risks. However, in reality, the existing technology infrastructure of digital healthcare systems is insufficient, failing to satisfy current and future data needs. Objective: This paper systematically reviews emerging information technologies for data modelling and analytics that have potential to achieve Data-Centric Health-Care (DCHC) for the envisioned objective of sustainable healthcare. The goal of this review is to: 1) identify emerging information technologies with potential for data modelling and analytics, and 2) explore recent research of these technologies in DCHC. Findings: A total of 1619 relevant papers have been identified and analysed in this review. Of these, 69 were probed deeply. Our analysis found that the extant research focused on elder care, rehabilitation, chronic diseases, and healthcare service delivery. Use-cases of the emerging information technologies included providing assistance, monitoring, self-care and self-management, diagnosis, risk prediction, well-being awareness, personalized healthcare, and qualitative and/or quantitative service enhancement. Limitations identified in the studies included vendor hardware specificity, issues with user interface and usability, inadequate features, interoperability, scalability, and compatibility, unjustifiable costs and insufficient evaluation in terms of validation. Conclusion: Achievement of a predictive universal digital healthcare ecosystem in the current context is a challenge. State-of-the-art technologies demand user centric design, data privacy and protection measures, transparency, interoperability, scalability, and compatibility to achieve the SDG objective of sustainable healthcare by 2030

Prescribing trends of proton pump inhibitors, antipsychotics and benzodiazepines of medicare part d providers

Background: Proton pump inhibitors, benzodiazepines, and antipsychotics are considered potentially inappropriate medications in older adults according to the American Geriatric Society Beers Criteria, and deprescribing algorithms have been developed to guide use of these drug classes. The objective of this study was to describe the number of beneficiaries prescribed these medications, provider specialty and regional trends in prescribing, and the aggregate costs for these claims in Medicare Part D. Methods: This was a retrospective cross-sectional study using publicly available Medicare Provider Utilization and Payment Data: Part D Prescriber data for years 2013–2019. Descriptive statistics and the Cochrane-Armitage test were used to summarize the trends. Results: Overall, 30.1%, 25.6%, 4.6% of Medicare Part D beneficiaries had a proton pump inhibitor, benzodiazepine, and antipsychotic claim in 2013, respectively. These rates decreased to 27.5%, 17.5%, 4.1% in 2019 (p-value \u3c 0.0001). However, the number of standardized 30-day claims increased from 63 million in 2013 to 84 million in 2019 for proton pump inhibitors, remained steady for benzodiazepines and slightly increased (10 million to 13 million) for antipsychotics. Total aggregate costs decreased by almost $1.5 billion for proton pump inhibitor,$100 million for benzodiazepine, and $700 million for antipsychotic from 2013 to 2019 (p-value \u3c 0.0001). Almost 93% of gastroenterologists prescribed a proton pump inhibitor, and 60% of psychiatrists prescribed benzodiazepines and antipsychotics all seven years. The Other region had the highest percentage of providers prescribing all three classes and the highest number of standardized 30-day benzodiazepine claims. Conclusions: The overall rate of use of proton pump inhibitors, benzodiazepines, and antipsychotics decreased from 2013–2019 among Medicare Part D beneficiaries. Despite the increase in raw number of standardized 30-day claims, the costs decreased which is likely due to generics made available. These prescribing trends may aid in identifying and targeting potential deprescribing interventions

STEM education from the perspective of The University of Sydney STEM Teacher Enrichment Academy

While STEM education is attracting much attention and is strongly advocated for, delivering on the promise of STEM education is still being researched (Rosicka, 2016; Margot & Kettler, 2019). The quest is on for understanding the essentials of STEM education and how to prepare teachers to capture the essence of STEM education in their professional practice. Drawing on ongoing research, the STEM Teacher Enrichment Academy, established within The University of Sydney in 2014, has developed in-service programs for teachers of both primary and secondary schools. The Academy is driven by the belief that STEM education is not a ‘fad’ and has the potential to transform pedagogy, thus motivating and enthusing students to participate more fully in the STEM disciplines, continue into senior secondary STEM subjects and beyond, ultimately addressing a shortage in STEM-related careers. With an expanding alumnus, currently at 800 teachers from 139 high schools and 370 teachers from 90 primary schools, the Academy has gathered scholarly evidence for the effectiveness and impact of its programs (Anderson, 2019; Anderson, Wilson, Tully, & Way, 2019). This presentation will share the design and structure of the Academy’s evidence-based programs as well as research on its efficacy. REFERENCES Margot, K. C. & Kettler, T. (2019).
