TL;DR: This work proposes Krippendorff's alpha as the standard reliability measure, general in that it can be used regardless of the number of observers, levels of measurement, sample sizes, and presence or absence of missing data.
Abstract: In content analysis and similar methods, data are typically generated by trained human observers who record or transcribe textual, pictorial, or audible matter in terms suitable for analysis. Conclusions from such data can be trusted only after demonstrating their reliability. Unfortunately, the content analysis literature is full of proposals for so-called reliability coefficients, leaving investigators easily confused, not knowing which to choose. After describing the criteria for a good measure of reliability, we propose Krippendorff's alpha as the standard reliability measure. It is general in that it can be used regardless of the number of observers, levels of measurement, sample sizes, and presence or absence of missing data. To facilitate the adoption of this recommendation, we describe a freely available macro written for SPSS and SAS to calculate Krippendorff's alpha and illustrate its use with a simple example.

TL;DR: Empirical and conceptual developments over the past four years on attitudes and persuasion are reviewed, with particular attention paid to work on attitude accessibility, ambivalence, and the affective versus cognitive bases of attitudes.
Abstract: ▪ Abstract We review empirical and conceptual developments over the past four years (1992–1995) on attitudes and persuasion. A voluminous amount of material was produced concerning attitude structure, attitude change, and the consequences of holding attitudes. In the structure area, particular attention is paid to work on attitude accessiblity, ambivalence, and the affective versus cognitive bases of attitudes. In persuasion, our review examines research that has focused on high effort cognitive processes (central route), low effort processes (peripheral route), and the multiple roles by which variables can have an impact on attitudes. Special emphasis is given to work on cognitive dissonance and other biases in message processing, and on the multiple processes by which mood influences evaluations. Work on the consequences of attitudes focuses on the impact of attitudes on behavior and social judgments.

TL;DR: Older monozygous twins exhibited remarkable differences in their overall content and genomic distribution of 5-methylcytosine DNA and histone acetylation, affecting their gene-expression portrait, indicating how an appreciation of epigenetics is missing from the understanding of how different phenotypes can be originated from the same genotype.
Abstract: Monozygous twins share a common genotype. However, most monozygotic twin pairs are not identical; several types of phenotypic discordance may be observed, such as differences in susceptibilities to disease and a wide range of anthropomorphic features. There are several possible explanations for these observations, but one is the existence of epigenetic differences. To address this issue, we examined the global and locus-specific differences in DNA methylation and histone acetylation of a large cohort of monozygotic twins. We found that, although twins are epigenetically indistinguishable during the early years of life, older monozygous twins exhibited remarkable differences in their overall content and genomic distribution of 5-methylcytosine DNA and histone acetylation, affecting their gene-expression portrait. These findings indicate how an appreciation of epigenetics is missing from our understanding of how different phenotypes can be originated from the same genotype.

TL;DR: The Committee concluded that the prevalence of vitamin D inadequacy in North America has been overestimated and urgent research and clinical priorities were identified, including reassessment of laboratory ranges for 25-hydroxyvitamin D, to avoid problems of both undertreatment and overtreatment.
Abstract: This article summarizes the new 2011 report on dietary requirements for calcium and vitamin D from the Institute of Medicine (IOM). An IOM Committee charged with determining the population needs for these nutrients in North America conducted a comprehensive review of the evidence for both skeletal and extraskeletal outcomes. The Committee concluded that available scientific evidence supports a key role of calcium and vitamin D in skeletal health, consistent with a cause-and-effect relationship and providing a sound basis for determination of intake requirements. For extraskeletal outcomes, including cancer, cardiovascular disease, diabetes, and autoimmune disorders, the evidence was inconsistent, inconclusive as to causality, and insufficient to inform nutritional requirements. Randomized clinical trial evidence for extraskeletal outcomes was limited and generally uninformative. Based on bone health, Recommended Dietary Allowances (RDAs; covering requirements of ≥97.5% of the population) for calcium range...
