Nonconvergence,improper solutions,and starting values in lisrel maximum likelihood estimation 总被引:1,自引:0,他引:1
Anne Boomsma 《Psychometrika》1985,50(2):229-242
In the framework of a robustness study on maximum likelihood estimation with LISREL three types of problems are dealt with: nonconvergence, improper solutions, and choice of starting values. The purpose of the paper is to illustrate why and to what extent these problems are of importance for users of LISREL. The ways in which these issues may affect the design and conclusions of robustness research is also discussed. 相似文献

语义联系类型和强度对预期推理生成的制约作用 总被引:3,自引:2,他引:1
首先采用开放式问卷实验方法,由被试生成日常生活中的事件以及组成这些事件的各种活动和活动的参加者。然后,对这些事件熟悉性、对活动的典型性和可区分性三个维度进行主观评价,形成事件以及每个事件活动序列,并据此编制实验材料。实验主要考察活动的典型性和可区分性对于熟悉性高的事件的预期推理的影响,以及不同工作记忆能力的被试进行事件预期推理时的加工模式。实验结果表明:(1)高工艺记忆能力的被试对事件的预期量小于 相似文献

Recent studies have documented substantial variability among typical listeners in how gradiently they categorize speech sounds, and this variability in categorization gradience may link to how listeners weight different cues in the incoming signal. The present study tested the relationship between categorization gradience and cue weighting across two sets of English contrasts, each varying orthogonally in two acoustic dimensions. Participants performed a four-alternative forced-choice identification task in a visual world paradigm while their eye movements were monitored. We found that (a) greater categorization gradience derived from behavioral identification responses corresponds to larger secondary cue weights derived from eye movements; (b) the relationship between categorization gradience and secondary cue weighting is observed across cues and contrasts, suggesting that categorization gradience may be a consistent within-individual property in speech perception; and (c) listeners who showed greater categorization gradience tend to adopt a buffered processing strategy, especially when cues arrive asynchronously in time. 相似文献

以往炫耀性消费研究多囿于自尊补偿视角,本文着眼于驱动炫耀性消费动机的自我增强属性,提出敬畏的自我超越属性可以降低个体对自身目标重要性的评估(即提升“小我”水平),进而降低炫耀性消费倾向。四个研究采用三种炫耀性消费倾向测量方式,通过测量特质敬畏(研究1a)和操纵状态敬畏(研究1b)均验证了敬畏对炫耀性消费倾向的抑制作用。研究2表明敬畏不影响非炫耀性消费倾向。研究3发现“小我”在敬畏与炫耀性消费倾向之间起到了中介作用。 相似文献

AbstractIn this research, we hypothesized that employees’ belief in a just world (BJW) would be positively related to their voice behavior, i.e., the expression of ideas or opinions with the intention of engendering organizational improvement or change, and that this relation would be mediated by perceived voice efficacy and perceived voice risk. To test these hypotheses, we collected self-reported data from employees in two different countries: China (N?=?313) and Germany (N?=?190). The results revealed a positive association between BJW and employee voice behavior in both samples. The two-mediator model was confirmed in the Chinese sample, while only perceived voice efficacy played a mediating role in the German sample. Possible reasons for these differences may be related to differences in cultural dimensions and education levels between the samples. The findings emphasize the importance of bolstering employees’ belief in justice and the organizational climate, which influence perceived voice efficacy and risk, as means to increase organizational voice behavior. 相似文献

I present the scope andcharacteristics of Marx's interest in Russiaand review its evolution. Initially, Marx'sattitudes were marked by russophobia,pronounced anti-panslavism, assessments ofRussia as an outpost of European reaction andcounterrevolution, and even as the head of aconspiracy to block the world revolution. Withtime, however, Marx came to consider Russia asthe country in which the outbreak of theRevolution was most likely. In his research forsucessive volumes of Capital, he readRussian theoretical works by, among others, V.Bervi-Flerovskij and A. Koshelev. Marx'sattitudes to the anticipated peasant revolutionin Russia remained ambivalent; to a certaindegree he feared its occurrence suspecting thatit could take on an `asiatic' hue. 相似文献

15名被试在摄人酒精BAL≤0.5‰前后的四个时段内接受一套简单的运算操作任务,近2/3被试的认知一操作能力显示受酒精影响发生变异:酒后30分钟操作时间延滞,至60分钟更具显著性;同时,操作错误亦大幅上升,但变化趋势不同于操作时间。酒精干扰呈现认知“近视”与“远视”的迹象。 相似文献

Professional autonomy is often described as a claim of professionalsthat has to serve primarily their own interests. However, it can also beseen as an element of a professional ideal that can function as astandard for professional, i.e. medical practice. This normativeunderstanding of the medical profession and professional autonomy facesthree threats today. 1) Internal erosion of professional autonomy due toa lack of internal quality control by the medical profession; 2)the increasing upward pressure on health care expenses that calls for ahealth care policy that could imply limitations for the professionalautonomy of physicians; 3) a distorted understanding of theprofession as being based on a formal type of knowledge and relatedtechnology, in which other normative dimensions of medical practice areneglected and which frustrates meaningful communication betweenphysicians and patients. To answer these threats a normative structureanalysis of medical practice is presented, that indicates whichprinciples and norms are constitutive for medical practice. It isconcluded that professional autonomy, normatively understood, should bemaintained to avoid the lure of the technological imperative and toprotect patients against third parties' pressure to undertreatment.However, this professional autonomy can only be maintained if members ofthe profession subject their activities and decisions to a criticalevaluation by other members of the profession and by patients and ifthey continue to critically reflect on the values that regulate today'smedicine. 相似文献

This paper argues that both the relativist and the pessimist critiques of the idea of progress are inadequate. Progress is defined as increase in global quality of life (QOL). Such QOL is intrinsically subjective, but not relative. It can be reliably measured through life satisfaction-type questions. The World Database of Happiness provides extensive data on social, economic and psychological factors that correlate with overall QOL. They include wealth, health, security, knowledge, freedom and equality. Various statistical data suggest that all these QOL indicators have undergone significant improvements during the last half century, in most of the world. This gives strong support to the thesis that progress objectively occurs. 相似文献
