基因研究中的知情同意之惑

知情同意作为生命伦理的重要原则,在基因研究中同样占据重要的地位,由于基因研究中知情同意的异质性,在基因研究中面临着诸如如何理解其知情同意的异质性、群体知情同意、基因知情与基因隐私、利益冲突等问题.通过分析基因研究中知情同意的特殊性,综合国内外此领域的已有研究,运用理论联系实际的方法,得出结论认为,只有正确区分基因知情与基因隐私的权利主体,用伦理规范来解决利益冲突,在发展中不断完善知情同意,才能够取得科技与伦理的共赢.     

Social and Behavioral Researchers' Experiences With Their IRBs

This article examines the responsibilities of researchers who conduct exploratory research to provide a service to vulnerable respondents. The term “service” is used to denote the provision of a tangible benefit in relation to the research question that is apart from the altruistic research benefits. This article explores what this “service” could look like, who might be responsible for providing it, and the challenges associated with such a service. The article argues that not providing a tangible benefit to vulnerable research participants is inconsistent with the principle of social justice that undergirds much of the rationale for conducting health disparities research.     

The Effects of Artist Adoration and Perceived Risk of Getting Caught on Attitude and Intention to Pirate Music in the United States and Taiwan

Piracy is the greatest threat facing the global music industry today. This study explores the effects of artist adoration and the perceived risk of being caught on the attitude and intention to engage in pirating a digital song among college students. The moderating effect of cultural environment factor is also examined. Experiments using between-group factorial designs were conducted in the United States and Taiwan. The results show that perceived risk of getting caught and cultural environment are important factors that can significantly affect the attitude and intention toward downloading unauthorized music. In addition, a two-way (Perceived Risk × Culture) and a three-way interaction in the model are also observed.     

Assessing At‐Risk Youth Using the Reynolds Adolescent Adjustment Screening Inventory With a Latino Population

Factor analyses were conducted on scores from the Reynolds Adolescent Adjustment Screening Inventory (RAASI; Reynolds, 2001 ) representing at‐risk Latino youth. The 4‐factor model of the RAASI did not exhibit a good fit. However, evidence of generalizability for Latino youth was noted.     

Human food preferences and cultural identity: The case of Aragón (Spain)

This research aims to analyze the relationship between sociocultural values and human food preferences. The latter, as shown in this paper, are greatly influenced by cultural identity. This work stems from a theoretical context that originated in Europe and the United States towards the mid‐twentieth century, within the field of the anthropology of food. A qualitative and quantitative analysis has been performed in the Comunidad Autónoma de Aragón (Spain). Research methods include focus groups, in‐depth interviews, participant observation, and a questionnaire that was handed out to a representative sample of the Aragonese population (816 people over 21 years of age; confidence level of 95.5% and error margin of ±3.5). Regarding the research outcome, a highly significant qualitative and quantitative connection has been found between food selection and cultural identity. In other words, people prefer to consume foods that are symbolically associated with their own culture, in order to reinforce their sense of belonging. Although this study has been carried out in Aragón, it is our belief that the results can be generalized to other areas. The originality and interest of our findings are notable considering that, to date, few works have analyzed the sociocultural factors motivating food behavior. Moreover, these results could be used by public and private organizations to meet objectives such as health promotion and product marketing.     

Simulating Personal Wealth in the Laboratory

During laboratory gambling tasks participants are not typically allowed to wager their personal wealth. Instead, wealth is simulated by telling participants they have been endowed with game tokens that will be later exchanged for money. Past research indicates that participants undervalue game tokens following this procedure, which leads to elevated risk taking compared to procedures that add saliency or realism to the monetary payoff. A between-subjects experiment tested whether showing a picture of money during the endowment instructions and repeating token-money exchange information during the session influenced participants' preference for risky and riskless options. The results showed no effect of the money picture. However, repeated token-money exchange information significantly decreased risk taking. Together with past studies, this finding suggests that endowment procedures might establish greater value in game tokens, and therefore better simulate personal wealth, when the eventual exchange between game tokens and money is made more salient to participants.     

Maternal Depressed Mood and Perceptions of Child Temperament

Research has suggested that women who experience postpartum depression are subsequently more likely to perceive their preschool-aged children as temperamentally difficult and maladjusted. However, previous studies have not controlled for the effects of concurrent depression levels on maternal ratings of child temperament or evaluated the accuracy of maternal reports. In the present study we assessed maternal and paternal ratings of child temperament 2 years after subjects had participated in a study of postpartum depression. The findings indicate that correlations between postpartum depression and subsequent child temperament ratings were accounted for statistically by concurrent levels of depression. Although fathers' ratings corroborated some aspects of maternal perceptions, levels of parental agreement were only moderately high. Moreover, discrepancies between the parents' reports were significantly associated with maternal depression, indicating that parental disagreement is more likely when the wife is dysphoric.     

Communal Versus Individual Learning of a Math-Estimation Task: African American Children and the Culture of Learning Contexts

The authors compared the performance of 78 African American 5th-grade students who studied a math-estimation task in one of two learning contexts. Learning contexts differed in the degree to which they afforded the expression of communalism. ANCOVA confirmed that posttest performance was best for students who studied in the high communal-learning context. The findings support A. W. Boykin's (1994) contention that the cultural context of learning can be a critical mediator of children's performance.     

False Memories in Individuals at Risk for Developing an Eating Disorder

In the present study, the authors used the Roediger and McDermott paradigm (H. L. Roediger & K. B. McDermott, 1995) to examine the creation of false memories in individuals at risk for developing an eating disorder. Thirty-three controls and 34 individuals at risk for eating disorders studied 6 word lists taken from the paradigm. Three lists were food related (bread, fruit, sweet), and 3 were not food related (king, doctor, black). Both groups produced false memories (i.e., recalled or recollected words that were not presented in the lists), and controls actually produced more false memories than the at-risk individuals produced in the recall of the food-related items. Groups did not differ in their recall of items not related to food.     

Competition and men’s face preferences

Several studies have examined potentially adaptive shifts and sources of individual differences in women’s face preferences, but relatively few studies have looked for similar findings in men. Evidence suggests that men of higher mate-value may be better placed to compete for relationships with higher-quality women, and that contest competition may influence men’s perceptions of dominance. Here, we looked at the effects of winning/losing in male–male competition on men’s face preferences. Participants were randomly and unknowingly assigned to either win or lose the first-person shooter video game Counter-Strike: Source against an unseen male confederate who could control the outcome through game cheats. We found that, compared to men assigned to the losing condition, men assigned to the winning condition had significantly (p = 0.012) higher preferences for women’s facial femininity. Results suggest that the outcomes of male–male competition may alter men’s mate preferences.
