酸碱滴定可行性的经典理念及其存在的问题

酸碱滴定可行性的经典理念是以终点误差为根据，以弱酸的平衡浓度Csp和离解常数Ka来表征酸碱滴定可行性，并把CspKa≥10^-8作为表征酸碱滴定反应可行性的判据．这种观点是片面的，只有根据终点观测误差推导酸碱滴定可行性才有实际意义，即根据平衡浓度Csp和酸与碱之间滴定反应的平衡常数Kt来表征酸碱滴定可行性．相应地，表征酸碱滴定反应可行性的判据应该是CspKt≥10^6．     

Social‐emotional well‐being and resilience of children in early childhood settings – PERIK: an empirically based observation scale for practitioners

Compared with the traditional focus on developmental problems, research on positive development is relatively new. Empirical research in children's well‐being has been scarce. The aim of this study was to develop a theoretically and empirically based instrument for practitioners to observe and assess preschool children's well‐being in early childhood settings. The analysis of preschool teachers' ratings yields six dimensions of social‐emotional well‐being: (1) making contact/social performance, (2) self control/thoughtfulness, (3) self‐assertiveness, (4) emotional stability/coping with stress, (5) task orientation, (6) pleasure in exploration. Composite scales were constructed. PERIK consists of six scales of six items each. The scales differentiate in both the upper and lower range and despite their brevity have good psychometric qualities. The instrument was published together with a booklet containing examples of how PERIK observations can be employed in practical work with children.     

"倾听哲学"与"观的哲学"--诠释学发展的两种取向

伽达默尔奠定了"倾听哲学"的基础,但他同时也面对着在诠释过程中,作为生命本体体验的时间始终不在场的困境。德里达的解构主义与成中英建立本体诠释学的尝试,使我们看到了立足于汉字的文字中心论诠释传统,建立一种真正自由开放的"观的哲学"的可能性与必要性。

Building a whole school approach and teacher efficacy with English language learners

Current professional development initiatives show a preference for whole school approaches. However, pedagogy related to English language learners (ELLs) is often not widely dispersed in New Zealand primary schools, impacting on teacher efficacy with these learners. This paper discusses findings from a qualitative study which aimed to identify influences shaping the dispersal of ELL-related pedagogy in two schools in contrasting socio-economic areas. Data from semi-structured individual interviews with teachers at different class levels revealed unique patterns for the dispersal of ELL-related pedagogy in each school. Teacher data indicated that these patterns were influenced by the performance of ELLs in national standards testing, as well as the special characteristics of ELLs in each setting and the distinctive nature of each context. The dispersal of ELL pedagogy in each school impacted differentially on opportunities to build a sense of collective teaching efficacy with ELLs in that setting, but also raised questions about whether one size should be expected to fit all.     

田野调查法在民族学研究中的作用

我国早期的民族学研究方法大多来自西方,本土化水平并不高,但随着国内民族学学科发展,研究方法也愈渐成熟,作为民族学学科的主要研究方法,田野调查法也日益展现出其重要作用。但对于年轻的研究者来说,如何去运用这个方法却面临着种种问题,如书面知识与实际操作化的差异,参与观察中价值中立的原则性难题,学科道德规范与世俗伦理的碰撞,何为真实性的原则问题等。即使在田野调查法如此成熟的今天,研究者进行实际操作时仍然面临不少问题,而这些问题对民族学学科发展提出了新的挑战。同时也是对研究者的挑战,对研究者提出更高的要求:要拥有创新意识,拓宽思维模式,为民族学开创新的道路。

丹栀逍遥散配合心理干预治疗艾滋病抑郁症60例临床观察

目的:探讨和研究丹栀逍遥散配合心理干预治疗艾滋病抑郁症患者的临床效果。方法:采用口服丹栀逍遥散治疗30例,并予应用HARRT药物和常规对症治疗的30例进行对照观察,两组疗程均为8周。结果:两组间比较无显著性差异(P>0.05),但两组治疗后汉密尔顿抑郁量表(HAMD量表)评分均较治疗前改善(P<0.05),且治疗后的治疗组评分低于对照组(P>0.05)。结论:治疗艾滋病抑郁症应用丹栀逍遥散配合心理干预有良好的疗效。
