对15种测验等值方法的比较研究

此项研究通过试验方法对４种基于经典测验理论的等值方法和１１种基于项目反应理论的等值方法进行了比较研究。研究数据为ＨＳＫ正式考试的数据,研究采用了较为可靠的检验标准。研究结果表明,在有些情况下,进行等值处理并非是最好的选择;在题库建设中,某些ＩＲＴ方法是可行的;至少对于ＨＳＫ数据,不论是单、双、三参数,不论是ｍｓ方法和ｍｍ方法,ＩＲＴ参数转换等值方法的误差都较大,均不足取。     

They do what they are told to do: the influence of instruction on (chess) expert perception-commentary on linhares and brum (2007)

Linhares and Brum (2007) argue that they provide evidence for analogy as the main principle behind experts' acquisition of perceptual knowledge. However, the methodology they used—asking players to pair positions using abstract similarity—raises the possibility that the task reflects more the effect of directional instructions than the principles underlying the acquisition of knowledge. Here we replicate and extend Linhares and Brum's experiment and show that the matching task they used is inadequate for drawing any conclusions about the nature of experts' perception. When expert chess players were instructed to match problems based on similarities at the abstract level (analogy), they produced more abstract pairs than pairs based on concrete similarity. However, the same experts produced more concrete pairs than abstract ones when instructed to match the problems based on concrete similarity. Asking experts to match problems using explicit instructions is not an appropriate way to show the importance of either analogy or similarity in the acquisition of expert knowledge. Experts simply do what they are told to do.     

“Other selves”: moral and legal proposals regarding the personhood of cryopreserved human embryos

This essay has two purposes. The first is to argue that our moral duties towards human embryos should be assessed in light of the Golden Rule by asking the normative question, “how would I want to be treated if I were an embryo?” Some reject the proposition “I was an embryo” on the basis that embryos should not be recognized as persons. This essay replies to five common arguments denying the personhood of human embryos: (1) that early human embryos lack ontological individuation; (2) that they are members of the species Homo sapiens but not yet human persons; (3) that the argument for personhood commits the “heap argument” fallacy; (4) that since human procreation in nature is inefficient, human embryos cannot be persons; and (5) the “burning building” scenario proves that all arguments for personhood are irrational or inconsistent. The second purpose is to set forth and criticize in light of the normative judgement defended in part one the present legal situation of cryo-preserved embryos in the U.S. The essay ends by proposing legislative reforms to protect ex utero human embryos.     

政策满意度、教师支持对免费师范生职业认同的作用:从教动机的中介效应

本研究以733名免费师范生为被试,采用问卷测量法,考察师范生对免费教育政策的满意度、所感知到的教师支持,及其师范生从教动机与职业认同的特点及其相互之间的关系,并检验了从教动机在政策满意度、教师支持与职业认同之间的中介效应。结果表明：（1）师范生在政策满意度、从教动机上存在年级差异,在职业认同上存在年级和性别差异。（2）政策满意度、教师支持、从教动机与职业认同两两之间均呈显著正相关。（3）政策满意度与教师支持对职业认同的直接效应显著,从教动机在政策满意度与职业认同之间、教师支持与职业认同之间均起部分中介作用,其中从教动机对政策满意度的中介效应显著高于对教师支持的中介效应。本研究围绕这些结果进行了讨论,并提出了相应的建议和对策。     

Parent–child value similarity in families with young children: The predictive power of prosocial educational goals

Value transmission from one generation to the next is a key issue in every society, but it is not clear which parents are the most successful in transmitting their values to their children. We propose parents’ prosocial educational goals as key predictors of parent–child value similarity. Accordingly, we hypothesized that the more parents wanted their children to endorse values of self‐transcendence (helping, supporting, and caring for others) and the less parents wanted their children to endorse the opposing values of self‐enhancement (striving for power and achievement), the higher would be parent–child overall value similarity. Findings from two studies of families – Study 1: 261 Swiss families, children aged 7–9 years; Study 2: 157 German families, children aged 6–11 years – confirmed this hypothesis. The effect was even stronger after controlling for values that prevail in the Swiss and German society, respectively. We integrate evidence from this study of values in families with young children with existing findings from studies with adolescent and adult children, and we discuss potential pathways from parents’ educational goals to parent–child value similarity.     

Understanding Our Understanding of Strategic Scenarios: What Role Do Chunks Play?

There is a crucial debate concerning the nature of chess chunks: One current possibility states that chunks are built by encoding particular combinations of pieces-on-squares (POSs), and that chunks are formed mostly by "close" pieces (in a "Euclidean" sense). A complementary hypothesis is that chunks are encoded by abstract, semantic information. This article extends recent experiments and shows that chess players are able to perceive strong similarity between very different positions if the pieces retain the same abstract roles in both of them. This casts doubt on the idea that POS information is the key information encoded in chess chunks, and this article proposes, instead, that the key encoding involves the abstract roles that pieces (and sets of pieces) play-a theoretical standpoint in line with the research program in semantics that places analogy at the core of cognition.     

改良教育心理学:来自认知神经科学的影响

在教育心理学发展了百余年之后,脑研究以认知神经科学的形式,重新回到她的怀抱。认知神经科学对教育心理学的影响,主要体现在能力、学习和教学上;对这两个领域的关系,应采用开放而谨慎态度,以促进各自研究的科学发展。     

Has Emergency Medicine Research Benefited Patients? An Ethical Question

From an ethical standpoint, the goal of clinical research is to benefit patients. While individual investigations may not yield results that directly improve patients’ evaluation or treatment, the corpus of the research should lead in that direction. Without the goal of ultimate benefit to patients, such research fails as a moral enterprise. While this may seem obvious, the need to protect and benefit patients can get lost in the milieu of clinical research.Many advances in emergency medicine have been based upon the results of research studies conducted both within the specialty and by others outside of the field. But has this research benefited patients? Has it followed the Hippocratic commitment “to do good or at least do no harm”? The answer is: yes, and no. This paper attempts to demonstrate this: first by citing advances from applied research that have benefited emergency department patients over the past three decades, and follows with some aspects of emergency medicine research that makes one question both its safety and its efficacy. While enormous gains have been made in patient care as a result of emergency medical research, ethical considerations complicate this rosy picture, and point to future areas of concern for researchers.Some aspects of clinical research and research oversight fall short of meeting the ethical standards of safety and patient benefit. Research agendas are still driven largely by the availability of funds, both from private industry and from government agencies. Many vital patient groups are harmed by omitting or sorely under-representing them as research subjects, most notably those that are critically ill and injured. Finally, questions still arise about clinical researchers’ fiduciary responsibility to their subject-patients. Even more important than the institutional safeguards, such as the Institutional Review Boards, is the individual researcher’s moral compass, which must serve to protect the subject-patients of clinical research.Overall, emergency medicine research has been and continues to be a moral endeavor. Perhaps the greatest moral lapse has been the lack of attention to key populations within emergency medicine research, and the patients most needing acute intervention are the ones who suffer.
