The Cigarette Purchase Task is a behavioral economic assessment tool designed to measure the relative reinforcing efficacy of cigarette smoking across different prices. An exponential demand equation has become a standard model for analyzing purchase task data, but its utility is compromised by its inability to accommodate values of zero consumption. We propose a two‐part mixed effects model that keeps the same exponential demand equation for modeling nonzero consumption values, while providing a logistic regression for the binary outcome of zero versus nonzero consumption. Therefore, the proposed model can accommodate zero consumption values and retain the features of the exponential demand equation at the same time. As a byproduct, the logistic regression component of the proposed model provides a new demand index, the “derived breakpoint”, for the price above which a subject is more likely to be abstinent than to be smoking. We apply the proposed model to data collected at baseline from college students (N = 1,217) enrolled in a randomized clinical trial utilizing financial incentives to motivate tobacco cessation. Monte Carlo simulations showed that the proposed model provides better fits than an existing model. We note that the proposed methodology is applicable to other purchase task data, for example, drugs of abuse. 相似文献

The purpose of this study was to explore how environmental factors (family environment and school education) and individual characteristics (personality, creative attitudes, and divergent thinking) collectively affect creative achievement of American and Chinese college students. Data were collected from 378 college students in the United States (N = 193) and China (N = 185). Results showed that the US sample had significantly higher means in home resources, high-school education, Conscientiousness, creative achievement, and all four dimensions of the Abbreviated Torrance Test for Adults (ATTA) than the China sample. In contrast, the China sample scored significantly higher in understanding the importance of creativity. Results indicated creative attitudes and divergent thinking sequentially mediated the effects of parental values on creative achievement for the US sample, whereas Openness mediated the effect of high-school education on creative achievement for the China sample. For both samples, creative attitudes mediated the effect of Openness on divergent thinking. The results suggested cultural differences in the effects of environmental factors on creativity, yet more similar findings in the effects of individual characteristics on creativity between the two samples. The results and implications are discussed. 相似文献

Family theory has refocused attention from deficits to family strengths, and interest in family resilience across cultures has become more widespread. However, few instruments were designed for quantitative research on family resilience. The Family Resilience Assessment Scale (FRAS) was designed to measure family resilience and has been administered in Western populations. The aim of this study was to adapt the FRAS for use with Chinese populations and examine its psychometric properties. The study was conducted using a sample of 991 university students in China (62.9 % female, mean age 20, SD = 1.12). First, the scale was translated and modified into Chinese, and good language equivalency was found. Next, confirmatory factor analysis was used to identify the best-fitting model. Results showed that the 3-factor model consisting of 32 items was an adequate fit. The goodness-of-fit index values for the model were χ 2/df = 5.97, CFI = .84, RMSEA = .08, SRMR = .05. Total scale reliability was α = .95. According to these values it can be said that the modified Chinese version of the FRAS was adapted successfully to the Chinese culture. Moreover, researchers and clinicians can use this instrument to assess family strengths when working with individuals in families experiencing adversity. 相似文献

This article is based on the author's extensive research on the missionaries to Tibet from the Disciples of Christ (Christian Church) USA, and discusses various missionary efforts to transmit scientific and practical knowledge such as medicine, building, and agriculture in Eastern Tibet from 1904–1919. It shows that American missionaries played a prominent and distinctive role in the dissemination of scientific and practical knowledge as a result of their hard work and wisdom. In this sense, they made an important contribution to the development of Tibetan society and the modernization movement in early twentieth‐century Eastern Tibet. 相似文献

This article argues against the non-cognitivist theory of vision that has been formulated in the work of Nico Orlandi. It shows that, if we understand ‘representation’ in the way Orlandi recommends, then the visual system’s response to abstract regularities must involve the formation of representations. Recent experiments show that those representations must be used by the visual system in the production of visual experiences. Their effects cannot be explained by taking them to be non-visual effects involving attention or memory. This contradicts Orlandi’s version of the non-cognitivist hypothesis, but does so while vindicating her methodological position. 相似文献
