John P. Liefeld 《Journal of Consumer Behaviour》2004,4(2):85-87
This paper reports an investigation of American and Canadian consumer acquisition and/or knowledge of the country of origin of products at the time of purchase. Consumer knowledge of the country of origin of purchased products was tested as purchasers left the cash register. If the purchaser knew the country of origin of the product just purchased, they were further questioned to discover the role such knowledge might have played in their choice between alternatives. More than 93 per cent of 1,248 purchasers intercepted at the cash register had not acquired while shopping, or did not know from prior experience, the country of origin of a product they had just purchased. Of the 91 (6.5 per cent) who had acquired or knew the country of origin of a product they had just purchased, only 27 (2.2 per cent of the total) indicated that their knowledge of the product's country of origin possibly might have played a role in their product choice. These findings reveal that the country of origin of products is not an important attribute in the choice processes of the great majority of North American consumers. Confirmation of these findings by replication with less obtrusive and more externally valid measures of consumer acquisition and use of product information prior to purchase is needed.

Statistics of Intuitionistic versus Classical Logics 总被引:2,自引:1,他引:1
For the given logical calculus we investigate the proportion of the number of true formulas of a certain length n to the number of all formulas of such length. We are especially interested in asymptotic behavior of this fraction when n tends to infinity. If the limit exists it is represented by a real number between 0 and 1 which we may call the density of truth for the investigated logic. In this paper we apply this approach to the intuitionistic logic of one variable with implication and negation. The result is obtained by reducing the problem to the same one of Dummett's intermediate linear logic of one variable (see [2]). Actually, this paper shows the exact density of intuitionistic logic and demonstrates that it covers a substantial part (more than 93%) of classical prepositional calculus. Despite using strictly mathematical means to solve all discussed problems, this paper in fact, may have a philosophical impact on understanding how much the phenomenon of truth is sporadic or frequent in random mathematics sentences. 相似文献

Data in social and behavioral sciences typically possess heavy tails. Structural equation modeling is commonly used in analyzing
interrelations among variables of such data. Classical methods for structural equation modeling fit a proposed model to the
sample covariance matrix, which can lead to very inefficient parameter estimates. By fitting a structural model to a robust
covariance matrix for data with heavy tails, one generally gets more efficient parameter estimates. Because many robust procedures
are available, we propose using the empirical efficiency of a set of invariant parameter estimates in identifying an optimal
robust procedure. Within the class of elliptical distributions, analytical results show that the robust procedure leading
to the most efficient parameter estimates also yields a most powerful test statistic. Examples illustrate the merit of the
proposed procedure. The relevance of this procedure to data analysis in a broader context is noted.

Stephen Goss 《Counselling and Psychotherapy Research》2003,3(2):155-158
This paper seeks to summarise recent discussions within the British Association for Counselling and Psychotherapy (BACP) about the strategic direction and priorities for the organisation, the profession as a whole and, ultimately, the service users. The standing research policy commitment to a pluralist approach to research is affirmed and a number of competing approaches are briefly considered. The direction of general policy and specific aims are noted. The paper does not seek to define a BACP position, as such, and is intended to stimulate further debate and discussion which will feed directly into the development of the BACP research policies and activities during this crucial development period. 相似文献

Inattentiveness and social desirability might be particularly problematic for self‐report scales in creativity and arts research. Respondents who are inattentive or who present themselves favorably will score highly on scales that yield positively skewed distributions and that assess socially valued constructs, such as scales measuring creativity and arts knowledge. A total of 204 undergraduates completed an online survey with several self‐report measures (the Creative Achievement Questionnaire, the Biographical Inventory of Creative Behavior, and the Aesthetic Fluency Scale). Many metrics of inattentiveness were included, such as directed response items, self‐reported attentiveness, and scales to catch inconsistent and patterned responses. The Balanced Inventory of Desirable Responding measured facets of social desirability. We found high rates of inattentive responding. A latent class analysis indicated that around 25% of the sample was potentially inattentive, and inattentive respondents received higher scores on the creativity and arts scales. Excluding problematic participants increased the effect sizes of interest, consistent with the coarsening effect of careless participants. Social desirability, in contrast, had essentially no relationship with the creativity and arts scales. These findings suggest that social desirability is probably less of a problem than researchers fear, but that inattentiveness is an underappreciated threat. Some practical guidelines are suggested. 相似文献

Reduction of cancer‐related disparities requires strategies that link medically underserved communities to preventive care. In this community‐based participatory research project, a public library system brought together stakeholders to plan and undertake programs to address cancer screening and risk behavior. This study was implemented over 48 months in 20 large urban neighborhoods, selected to reach diverse communities disconnected from care. In each neighborhood, Cancer Action Councils were organized to conduct a comprehensive dynamic trial, an iterative process of program planning, implementation and evaluation. This process was phased into neighborhoods in random, stepped‐wedge sequence. Population‐level outcomes included self‐reported screening adherence and smoking cessation, based on street intercept interviews. Event‐history regressions (n = 9374) demonstrated that adherence outcomes were associated with program implementation, as were mediators such as awareness of screening programs and cancer information seeking. Findings varied by ethnicity, and were strongest among respondents born outside the U.S. or least engaged in care. This intervention impacted health behavior in diverse, underserved and vulnerable neighborhoods. It has been sustained as a routine library system program for several years after conclusion of grant support. In sum, participatory research with the public library system offers a flexible, scalable approach to reduce cancer health disparities. 相似文献

本研究旨在探索自我欺骗的研究方法、产生的原因和认知机制,以及这一领域中有待解决的新问题。近期研究发现:基于自我欺骗产生的动机特点,主要存在三类不同的定义方式,大多数心理学家是基于第三类定义来研究自我欺骗。研究方法上,适用性较强的自欺问卷是自欺性提升量表(SDE),操作性较强的经典实验范式是点追踪任务。在认知过程的任一阶段中,调节心理状态是个体产生自我欺骗的直接动机,改变个体的心理状态或对事物的模糊感知可能阻止个体自我欺骗的产生。未来应从如何调节个体心理状态的角度探讨和研究自我欺骗,能够利用点追踪任务,结合ERPs或fMRI技术为之后研究自欺产生的具体阶段、认知机制以及神经机制提供实证研究基础。 相似文献

CD-CAT是CDA同CAT的相结合的产物,适用于课堂教学,是教师补救教学、学生自我学习的重要工具。作为CD-CAT重要组成部分的初始阶段项目选取方法是影响测验判准率的重要因素。本文基于现有研究和CDA的项目区分度提出了四种新的初始阶段项目选取方法:CTTID法、CDI法、CTTIDR*法和CDIR*法。通过模拟研究发现,在定长的CD-CAT下,题库质量是HD-HV下,初始阶段结束时,CTTIDR*法的PCCR比现有的T阵法高了.2999,比PWKL高了.1707,其它题库下趋势相同。整个测验结束时CTTIDR*法的判准率仍然是最高的。在变长的CD-CAT下,最大后验概率大于.7、.8、.9下,CTTIDR*法的被试平均测验长度比T阵法分别缩短了2.6170、2.2347、1.7470道题。 相似文献

摘 要 采用问卷法调查法,以广东省627 名中小学教师为被试,以结构方程模型考察组织特征、组织认同与教学方式转变的关系。结果表明:(1)组织特征能显著正向预测组织认同和教学方式转变,组织认同能显著正向预测教学方式转变。(2)组织认同在组织特征影响教学方式转变中起完全中介作用。这启示我们可以通过提升教师对他们所属学校的组织认同水平有效地促进其教学方式的转变。 相似文献
