Recovering the role of reasoning in moral education to address inequity and social justice

This article reasserts the centrality of reasoning as the focus for moral education. Attention to moral cognition must be extended to incorporate sociogenetic processes in moral growth. Moral education is not simply growth within the moral domain, but addresses capacities of students to engage in cross-domain coordination. Development beyond adolescence in moral thinking is in two forms: (1) the gradual application of morality in broader adult contexts, and (2) the result of social discourse and progressive readjustments at the individual and societal level of views of the morality of societal practices. Postconventional moral reasoning is not a rarified stage of moral cognition, but an orientation and set of discourse skills potentially available to all normally developing adult moral reasoners.     

关于教师的幼儿事务自主观念的研究

儿童对个人事务的自主权对其自我的发展、自主性的增强及个性的形成有着重要的意义。本研究对大连市区371名幼儿教师进行了问卷调查和访谈。结果表明：（1）教师区分了个人事务、道德事务和常规事务；（2）教师在各事务领域给予幼儿自主权限的程度差异显著；（3）教师在各事务领域对待幼儿的方式差异显著；（4）教师给予幼儿各事务自主权限的程度在教师工作年限、幼儿年龄等因素上的差异不显著。     

Domain Coloring and the Argument Principle

Abstract

The domain-coloring algorithm allows us to visualize complex-valued functions on the plane in a single image—an alternative to before-and-after mapping diagrams. It helps us see when a function is analytic and aids in understanding contour integrals. The culmination of this article is a visual discovery and subsequent proof of the Argument Principle, which relates the count of poles and zeros of a meromorphic function inside a contour to the accumulated change in argument of the function around the contour. Throughout, I offer connections to standard learning goals of courses in complex variables.     

果蝇振翅鸣声信号特征分析

发声是动物间进行交流的信息方式,声音信号的特征对应于动物的某种行为.以Matlab为工具,对采集到的雌、雄地中海果蝇飞行时振翅产生的声音进行了时域和频域的分析、比较,并提取其声音信号特征参数,即正常飞行鸣声的波形都为正弦波,声音的基频为147Hz,并带有多个谐波,其窄带声谱图具有良好的频率分辨率.研究还表明这种果蝇种内雌雄两性飞行时振翅特征有很大相似性.

互联网企业员工知识领地行为的研究

在对互联网企业发展形势和知识员工的个性特征分析的基础上,梳理相关文献和理论知识,界定知识领地行为概念,开发出知识领地行为量表,以深圳市五家大型互联网企业的245位员工为研究对象,研究员工的知识领地行为。研究发现,知识领地行为是普遍存在的;女性比男性员工有着更强烈的知识领地行为意向;高学历员工,尤其是具有博士学历的员工担当行为意向非常明显。     

Troponin T and Heart Type Fatty Acid Binding Protein (h-Fabp) as Biomarkers in Patients Presenting with Chest Pain

Acute coronary syndrome (ACS) is a term for a range of clinical signs and symptoms suggestive of myocardial ischemia. It results in functional and structural changes and ultimately releasing protein from injured cardiomyocytes. These cardiac markers play a major role in diagnosis and prognosis of ACS. This study aims to assess the efficacy of heart type fatty acid binding protein (h-FABP) as a marker for ACS along with the routinely used hs-TropT. In our observational study, plasma h-FABP (cut-off 6.32 ng/ml) and routinely done hs-Trop T (cutoff 0.1 and 0.014 ng/ml) were estimated by immunometric laboratory assays in 88 patients with acute chest pain. Based on the clinical and laboratory test findings the patients were grouped into ACS (n = 41) and non-ACS (n = 47). The diagnostic sensitivity, specificity, NPV, PPV and ROC curve at 95 % CI were determined. Sensitivity of hs-TropT (0.1 ng/ml), hs-TropT (0.014 ng/ml) and h-FABP were 53, 86 and 78 % respectively and specificity for the same were 98, 73 and 70 % respectively. Sensitivity, specificity and NPV calculated for a cut-off combination of hs-TropT 0.014 ng/ml and h-FABP was 100, 51 and 100 % respectively. These results were substantiated by ROC analysis. Measurement of plasma h-FABP and hs-TropT together on admission appears to be more precise predictor of ACS rather than either hs-Trop T or h-FABP.

对域名权利属性的再认识

域名权利属性问题的争论仍在继续,由于思路与方法不同,争执数年未能取得一致意见.从域名的民事权利属性、域名的知识产权属性和域名的法律独立性视角对域名的权利属性进行界定,域名应为受民法保护的权利,属于知识产权的范畴,为知识产权新客体.
