基于FESA/TRIZ的机械产品创新设计方法

机械产品的设计一直注重于市场需求和产品功能的开发，随着科学和技术的发展，环境因素变得越来越重要。 提出一种基于功能一环境一结构分析( FESA)与TRIZ的机械产品创新设计方法，通过分析机械产品结构之间的功能要素 以及功能要素与环境要素的相互作用关系，确定机械产品中存在的问题。建立根原因模型图，寻找结构设计上的不足和 缺陷，利用TRIZ创新理论来实现机械产品的改进创新。通过污水处理系统的创新设计实例验证了该方法的可行性。

陕南商洛客家方言入声演变的特点

商洛客家方言古入声今读的情况是塞音韵尾已全部丢失，入声韵尾脱落后，古入声韵或以主要元音相近为原则，归入相应的阴声韵，或独立成韵，相对比较复杂。入声调的今读情况各地也存在差异，罗湾保留阴入、阳入，安乐只有阴入，其他地方没有入声调，清入字或归上声或归阳入，全浊字都归去声，次浊入字部分随清入字走，部分随全浊入字走。

国家级教学名师的优秀品质及其养成

通过对5位国家级教学名师的自述报告进行三级编码和主题凝练，研究发现国家级教学名师作为教师队伍的杰出代表，在其专业发展过程中养成了许多优秀品质。例如：教学方面注重实践、考虑周全，师德方面以德施教、追求卓越，科研方面以教带研、实现创新。国家级教学名师优秀品质的养成通常经历了漫长而曲折的过程，不仅需要精神与物质力量的共同推动，还需要家庭、学校和社会各环境要素的相互促进，以及社会取向养成方式和个人取向养成方式的互相配合。深入探究国家级教学名师的优秀品质及其养成之道，可以为教师专业发展提供借鉴与启示。     

中国传统行政的善治理想及其现代影响——以黄宗羲为例

中国传统行政理论在长期发展中积累了丰富的内容,形成了完整的理论形态,并在明清之际达到了它近乎顶峰的极限状态,黄宗羲的善治理论就是它在这个阶段的重要代表。黄宗羲视域中的善治在内容及方式上,都延续了儒家传统主流观点。它在内容上首先要求圣王,即唯有圣王才能以“不忍人之心”行“不忍人之政”,所谓善治实际上就是“不忍人之政”;其次它还将善治的具体内容确定为养民与教民,“养民”就是使民足以事父母及畜妻子,养生送死无憾,“教民”就是用圣王学说教育民众,使民衣食住行都合乎礼;再次它还主张治理目的是使民皆“至于至善”和“止于至善”。中国传统行政理论的善治理想在现实中还有强劲的生命力,它既表现为行政的强烈伦理导向,又表现为一种主动作为的积极政府观,还表现为一种彻底的以人为本的人文主义。     

Explicit analytical solutions for ARL of CUSUM chart for a long-memory SARFIMA model

This paper aims to derive explicit analytical solutions for Average Run Length (ARL) of CUSUM chart for the SARFIMA(P,D,Q)_S process with exponential white noise. Measurement of performance was done with the ARL in terms of percentage error and CPU time. The results obtained from the explicit formulas were compared focusing on the performance using the numerical integral equation (NIE) method. Both methods had similarly excellent agreement with the percentage error at less than 0.25%. Meanwhile, the explicit formulas consumed less CPU time than the NIE method. It is clear that the explicit formulas are a good alternative in real applications.     

Developing critical and empathic capabilities in intercultural education through the VaKE approach

One of the core goals of intercultural education is to develop critical and empathic reflection on social justice, particularly as related to humanistic choices and how individuals can counteract exclusion. The present article analyses the Values and Knowledge Education (VaKE) approach, which is aimed at raising awareness about implicit value-oriented priorities in decision-making. Through the Human Development and Capability Approach, the applicability of VaKE’s didactic principles is analysed in relation to young people’s perspectives on resettlement in Europe. The VaKE method was used at a 2013 summer camp in Austria with a culturally diverse group of young Europeans who were presented with a dilemma story that highlighted the complex issue of providing assistance to asylum seekers. The participants engaged in various knowledge and moral viability checks that enabled them to engage with opposing arguments. The participants evidenced critical reflection and self-scrutiny, as well as affiliation and empathic imagination, regarding problems that are encountered by asylum seekers.     

Association between sexually explicit messages and sleep health among French sexual minority men

It has been demonstrated that sexual minority men (SMM) participate in sexting. While research has shown that engagement in the exchange of sexually explicit media is associated with poor health outcomes, no previous research has investigated its association with sleep health outcomes. This study sought to examine the association between sexually explicit media and sleep health among SMM, a population that suffers from poor sleep health. A popular geosocial networking application was used to recruit SMM individuals (N?=?580) in the Paris, France, metropolitan area. Multivariate analyses, adjusting for sociodemographics, were used to test the association between the frequency of sexually explicit messaging and three dimensions of sleep health: (1) sleep quality, (2) sleep duration, and (3) two aspects of sleep problems. In multivariate analyses, those who reported engaging in sexually explicit messaging more were more likely to report getting less than seven?hours of sleep (aRR = 1.24; 95% CI = 1.08, 1.43) compared with those who reported engaging in sexually explicit messaging less. No significant associations were found between sexting and sleep quality or reporting sleep problems. Sexually explicit messaging was associated with shorter sleep duration. Intervention targeted at individuals who sext could potentially improve sleep health outcomes.     

Social and feminist design in emergency contexts: the Women’s Social Architecture Project,Cox's Bazar,Bangladesh

ABSTRACT

The rapid influx of Rohingya refugees into Cox's Bazar, Bangladesh, has led to the formation of huge camps, built on difficult terrain, short of space and with high population density. All these factors present numerous challenges to agencies seeking to provide latrines, water points, and bathing facilities. Feedback gathered from women and girls highlighted significant challenges around access, safety, privacy, and dignity, including management of personal hygiene and menstruation. Within the humanitarian community, site planning and WASH (water, sanitation and hygiene) infrastructure planning/design processes have mainly been dominated by male architects and engineers, often with gendered assumptions about the user. Acknowledging these challenges, Oxfam implemented the Women’s Social Architecture Project to work with women and adolescent girls, and female architects with a background or interest in social or feminist design and architecture, to add a different perspective into the design and siting of WASH facilities. The project has consisted of formative research with Rohingya women and girls, and design workshops with architects in which Rohingya women have co-created designs that tackle the issues they face regarding WASH facilities. This article provides an account of the progress to date, together with feedback from women and girls and the WASH Sector in Cox's Bazar ahead of the final completion of the project in June 2019.
