For the interaction between the biostatistician and the clinician or research investigator to be successful, it is important not only for the investigator to be able to explain biological and medical principles in a way that can be understood by the biostatistician, so, too, the biostatistician needs tools to help the investigator understand both the practice of statistics and specific statistical methods. In our practice, we have found it useful to draw analogies between statistical concepts and familiar medical or everyday ideas. These analogies help to stress a point or provide an understanding on the part of the investigator. For example, explaining the reason for using a nonparametric procedure (a general procedure used when the underlying distribution of the data is not known or cannot be assumed) by comparing it to using broad spectrum antibiotics (a general antibiotic used when the specific bacteria causing infection is unknown or cannot be assumed) can be an effective teaching tool. We present a variety of useful (and hopefully amusing) analogies that can be adopted by statisticians to help investigators at all levels of experience better understand principles and practice of statistics. 相似文献

The issue of dual career couples has gained considerable relevance in recent years. On the one hand, this results in an increase in the number of publications. On the other hand, some companies have become to recognize the needs of dual career couples and utilize this specifically in the search for the ??high potentials??. Furthermore, it is demonstrated why it is also important for an internal coach to take into account the challenges, specifics and opportunities of dual career couples. The most common areas of tension are identified and illustrated basing on examples and experiences. 相似文献

The developmental period of adolescence is characterized by increasing incidence of health risk behaviors (HRBs). Based on theoretical models that emphasize the moderating role of cognitive control, this study examined how neural correlates of cognitive control and risk sensitivity interact to predict HRBs among late adolescents (17–20 years). Neuroimaging data indicate that risk‐related hemodynamic activity in the anterior insula during anticipation of uncertain outcomes predicts HRBs among late adolescents exhibiting greater dorsal anterior cingulate cortex (dACC) activity during a cognitive interference task but not among late adolescents requiring less dACC activity. These results present neural evidence for a significant moderating effect of cognitive control on the link between risk sensitivity and HRBs among late adolescents. 相似文献

Mixed methods researchers usually discuss how to combine qualitative and quantitative data of the same data type (typically interviews). However, mixed methods research becomes vastly more complicated, when not only standardized data are combined with more open-ended data but simultaneously different data types are mixed (e.?g. ethnographical data with survey data). Using two examples from spatial sociology, this paper illustrates that the specific benefit of such combinations is that ethnography and surveys provide complementary information. The paper also discusses how to solve some problems typically arising in mixed methods studies with mixed data types. In particular, which mixed methods design is most suitable, strongly depends on the specific research question and the social theory used. Regardless, researchers have to decide which strand of the mixed methods study is core component and which is supplemental component. 相似文献

Previous studies of risk behavior observed weak or inconsistent relationships between risk perception and risk-taking. One aspect that has often been neglected in such studies is the situational context in which risk behavior is embedded: Even though a person may perceive a behavior as risky, the social norms governing the situation may work as a counteracting force, overriding the influence of risk perception. Three food context studies are reported. In Study 1 (N = 200), we assess how norm strength varies across different social situations, relate the variation in norm strength to the social characteristics of the situation, and identify situations with consistently low and high levels of pressure to comply with the social norm. In Study 2 (N = 502), we investigate how willingness to accept 15 different foods that vary in terms of objective risk relates to perceived risk in situations with low and high pressure to comply with a social norm. In Study 3 (N = 1,200), we test how risk-taking is jointly influenced by the perceived risk associated with the products and the social norms governing the situations in which the products are served. The results indicate that the effects of risk perception and social norm are additive, influencing risk-taking simultaneously but as counteracting forces. Social norm had a slightly stronger absolute effect, leading to a net effect of increased risk-taking. The relationships were stable over different social situations and food safety risks and did not disappear when detailed risk information was presented. 相似文献
