关于一类二阶发展方程的反周期解

本研究了在Hilbert空间中与极大单调算子族相联系的抽象的二阶发展方程的反周期问题．给出了关于算子族{A(t)：0≤t≤T}的新的假设，并在此假设下证明了反周期解的存在性与惟一性，推广了已有的结果．最后给出一个例子说明抽象的反周期问题在非线性偏微分方程中的简单应用．     

The worldwide spread of peace education: discursive patterns in publications and international organisations

ABSTRACT

To investigate the spread of peace education (PE), we examined 685 documents in SCOPUS between 1970 and 2018 in 70 countries and triangulated the information with 11369 news articles and 22 international organisation? founding dates. PE emerged in scientific databases in the 1970s, lost momentum in 1990 and then globalised after 2003. PE’s institutionalisation was furthered by: (a) the increasing search for discourses that highlighted individual agency of self-declared ‘peace educators’; (b) educational expansion that generated a greater demand for so-called best practices; and (c) the active role of professionals working on organisations such as UNESCO, UNICEF and the identified international organisations. We recognised five loosely coupled narratives: PE’s (a) philosophical foundations and relationship to critical pedagogy; (b) application to improve international relationships; c) solution to internal conflicts; (d) measurements of interventions; (e) linkages to religion. We reflect on the implications of PE as an educational discourse in curricular reforms.

Spying on children during a school playground intervention using a novel method for direct observation of activities during outdoor play

Our aims were to examine the efficacy of a new observational instrument ‘System for Observing Outdoor Play’ for detecting changes in outdoor play and chart the use of recycled and repurposed materials in the school playground during the course of an intervention to increase outdoor play. Children from one Sydney primary school were observed (N = 111; 5–12 years) using an observational instrument developed as part of the Sydney Playground Project. Data on types of activities and frequencies were collected at baseline and seven times during intervention. Use of intervention materials was consistently high and associated with increases in play-related activities (40–77%), while inactive pursuits decreased (52–31%), on average. The observational instrument proved efficacious in tracking changes in play. Modification of the school playground environment by introducing loose parts changed children’s play-related behaviour; the variety of activities increased, including construction and creative play. Physical inactivity decreased. Recycled materials can increase children’s creative, social and physical play.
