This article deals with the issue of including gay, lesbian, and bisexual (GLB) themed materials in school curricula. It is argued not only that such materials should be included but also that the more radical notion of 'positive systematic inclusion' should be followed. Positive systematic inclusion requires the positive portrayal of GLB persons in the curriculum and prohibits teachers, at least in the early school years, from expressing opinions against homosexuality. Using a recent critique of this position provided in Sex Education by John Beck as a foil, the author argues that positive systematic inclusion is required by and promotes the liberal democratic tradition. Furthermore, positive systematic inclusion represents the radicalization of the liberal democratic tradition necessary to respond adequately to legitimate criticisms from postmodernists. 相似文献

Very few research papers and case studies have shown successful integration of both Facebook and Moodle in the educational experience of students. This study sought to evaluate the educational benefits of the increasingly popular Facebook—which plays an important role in students’ social life as well as their academic life—and to compare it with the widely used course management system Moodle. In this study, the authors surveyed students of the University of Belgrade’s Faculty of Organizational Science in Serbia on their attitude toward Facebook and Moodle as productive online tools for teaching and learning. An analysis of the results was carried out using the SPSS software package. The results of this research answer the question of whether or not using Facebook as an educational tool is more effective than using Moodle and how it affects students’ everyday learning activities. 相似文献

Introduction
Acute kidney injury (AKI) is significant problem in children with congenital heart disease (CHD) who undergo cardiac surgery. The economic impact of a biomarker-based diagnostic strategy for AKI in pediatric populations undergoing CHD surgery is unknown. The aim of this study was to perform the cost effectiveness analysis of using serum cystatin C (sCysC), urine neutrophil gelatinase-associated lipocalin (uNGAL) and urine liver fatty acid-binding protein (uL-FABP) for the diagnosis of AKI in children after cardiac surgery compared with current diagnostic method (monitoring of serum creatinine (sCr) level).Materials and methods
We developed a decision analytical model to estimate incremental cost-effectiveness of different biomarker-based diagnostic strategies compared to current diagnostic strategy. The Markov model was created to compare the lifetime cost associated with using of sCysC, uNGAL, uL-FABP with monitoring of sCr level for the diagnosis of AKI. The utility measurement included in the analysis was quality-adjusted life years (QALY). The results of the analysis are presented as the incremental cost-effectiveness ratio (ICER).Results
Analysed biomarker-based diagnostic strategies for AKI were cost-effective compared to current diagnostic method. However, uNGAL and sCys C strategies yielded higher costs and lower effectiveness compared to uL-FABP strategy. uL-FABP added 1.43 QALY compared to current diagnostic method at an additional cost of $8521.87 per patient. Therefore, ICER for uL-FABP compared to sCr was $5959.35/QALY.Conclusions
Our results suggest that the use of uL-FABP would represent cost effective strategy for early diagnosis of AKI in children after cardiac surgery.Key words: acute kidney injury, cardiac surgery, children, biomarkers, cost effectiveness analysis 相似文献6.

ABSTRACT In her recent book, All Must Have Prizes, Melanie Phillips makes several claims about the ‘disastrous’ influence that John Dewey had on education in the UK. The problem is that Phillips gets Dewey quite wrong. She is, of course, not alone in her misreading of Dewey. Using Phillips as a point of departure, I present several misinterpretations of Dewey. Specifically, Phillips and others make the following claims: (1) Dewey promoted ahistoric and cultureless education; (2) Dewey sacrificed knowledge, facts, and subject matter to skills and processes; (3) Dewey rejected the authority of teachers. I point out how Dewey speaks explicitly to each of these assertions. 相似文献

Introduction:
Urinary tract infection (UTI) is one of the most common bacterial infectious diseases in children. The aim of this study was to determine the total prooxidant and antioxidant capacity of children with UTI, as well as changes of oxidative status parameters according to acute inflammation persistence and acute kidney injury (AKI) development.Materials and methods:
The patients enrolled in the study comprised 50 Caucasian children (median age was 6 months) with UTI. Total oxidant status (TOS), total antioxidant status (TAS), oxidative stress index (OSI), inflammation marker C-reactive protein (CRP) and renal function parameters urea and creatinine were analyzed in patient’s serums.Results:
According to duration of inflammation during UTI, TAS values were significantly higher (0.99 vs. 0.58 mmol/L, P = 0.017) and OSI values were significantly lower (0.032 vs. 0.041 AU, P = 0.037) in the subjects with longer duration of inflammation than in the subjects with shorter duration of inflammation. We did not find significant difference in basal values of oxidative status parameters according to AKI development.Conclusions:
OSI values could detect the simultaneous change of TAS and TOS due to change in the oxidative-antioxidant balance during the recovery of children with UTI. TAS and OSI as markers of oxidative stress during UTI are sensitive to accompanying inflammatory condition. Further investigations are needed to evaluate whether TAS, TOS and OSI could be used to monitor disease severity in children with UTI. 相似文献8.

The Multiple Indicator Cluster Survey (MICS) is a nationally representative, internationally comparable household survey implemented to examine protective and risk factors of child development in developing countries around the world. This introduction describes the conceptual framework, nature of the MICS3, and general analytic plan of articles in this Special Section. The articles that follow describe the situations of children with successive foci on nutrition, parenting, discipline and violence, and the home environment. They address 2 common questions: How do developing and underresearched countries in the world vary with respect to these central indicators of children’s development? How do key indicators of national development relate to child development in each of these substantive areas? The Special Section concludes with policy implications from the international findings. 相似文献

Teaching about homosexuality, especially in a positive light, has long been held to be a controversial issue. There is, however, a view of the capacity for reason that finds that those who deem homosexuality to be controversial will ultimately contradict themselves, becoming unreasonable. By this standard of reason, homosexuality should be treated as non controversial in schools. In this essay, John Petrovic argues that this epistemic position is problematic. Instead, he defends a Deweyan epistemology that casts reason as, in part, a set of socially acquired habits of mind. People who have been socialized into heterosexist habits of mind must be exposed to counterhegemonic discourses. One such discourse can be found in the public values of liberal democracy through which the practice of reason must be pursued. Petrovic discusses the practical guidance provided by assuming a view of normative reason versus habituated reason in terms of both pedagogy and curriculum. 相似文献

AbstractThe authors present a materialist analysis of the effects of neoliberalism in education. Specifically, they contend that neoliberalism is a form of cultural invasion that begets necrophilia. Neoliberalism is necrophilous in promoting a cultural desire to fix fluid systems and processes. Such desire manufactures both individuals known and culturally felt experiences of alienation which are, it is argued, symptomatic of an imperialist nostalgia that permeates educational policy and practice. The authors point to ‘unschooling in schools’ as a mechanism for resisting the necrophilous tendencies of contemporary formations of education. 相似文献
