Literature on maternal exposures and the risk of epigenetic changes or diseases in the offspring is growing. Paternal contributions are often not considered. However, some animal and epidemiologic studies on various contaminants, nutrition, and lifestyle‐related conditions suggest a paternal influence on the offspring's future health. The phenotypic outcomes may have been attributed to DNA damage or mutations, but increasing evidence shows that the inheritance of environmentally induced functional changes of the genome, and related disorders, are (also) driven by epigenetic components. (...) In this essay we suggest the existence of epigenetic windows of susceptibility to environmental insults during sperm development. Changes in DNA methylation, histone modification, and non‐coding RNAs are viable mechanistic candidates for a non‐genetic transfer of paternal environmental information, from maturing germ cell to zygote. Inclusion of paternal factors in future research will ultimately improve the understanding of transgenerational epigenetic plasticity and health‐related effects in future generations. (shrink)

Idealism and relativism were designed to assess different ethical ideological views. Their relation with attitudes toward a variety of outgroups has not been previously studied. Understanding how concerns over ethical principles and consequences are related to prejudiced attitudes could provide some insight into these constructs and into the nature of prejudice. In two studies totaling 311 participants, participants completed measures on ethical ideologies, right-wing authoritarianism, and attitudes toward various outgroups. The differential predictive validities of ethical ideologies, in comparison to right-wing (...) authoritarianism, on prejudicial attitudes toward dangerous, derogated, and dissident outgroup members were examined. We found that both idealism and relativism contributed to predicting attitudes regarding outgroup members, over and above right-wing authoritarianism. As such, people’s personal moral standards and code of conduct for dealing with interpersonal problems and transgressions can partly explain their negative attitudes toward outgroup members. More research is required to determine the unique influence of ethical ideologies over other constructs previously shown to predict prejudice. (shrink)

Noncoding RNA has arrived at centre stage in recent years with the discovery of “hidden transcriptomes” in many higher organisms. Over two decades ago, noncoding transcripts were discovered in Drosophila Hox complexes, but their function has remained elusive. Recent studies1-3 have examined the role of these noncoding RNAs in Hox gene regulation, and have generated a fierce debate as to whether the noncoding transcripts are important for silencing or activation. Here we review the evidence, and show that, by taking developmental (...) timing into account, some of these apparently conflicting results can be resolved. We examine current models that explain these data and explore alternative interpretations. BioEssays 30:110–121, 2008. © 2008 Wiley Periodicals, Inc. (shrink)

What are the effects of our environment on human development and the next generation? Numerous studies have provided ample evidence that a healthy environment and lifestyle of the mother is important for her offspring. Biological mechanisms underlying these environmental influences have been proposed to involve alterations in the epigenome. Is there enough evidence to suggest a similar contribution from the part of the father? Animal models provide proof of a transgenerational epigenetic effect through the paternal germ line, but can this (...) be translated to humans? To date, literature on fathers is scarce. Human studies do not always incorporate appropriate tools to evaluate paternal influences or epigenetic effects. In reviewing the literature, I stress the need to explore and recognize paternal contributions to offspring's health within the Developmental Origins of Health and Disease hypothesis, and coin this new concept the Paternal Origins of Health and Disease paradigm. A better understanding of preconceptional origins of disease through the totality of paternal exposures, or the paternal exposome, will provide evidence-based public health recommendations for future fathers. A father's hereditary contribution exceeds that of his DNA sequence. The environment can regulate systems such as the sperm epigenome, which is inheritable as well and may steer the genome and health status of his offspring. We here suggest a new concept, the Paternal Origins of Health and Disease, as part of the DOHaD theory. (shrink)

Ideas surrounding mechanicism and materialism are so prevalent and fundamental in early modern and modern philosophy and critical theory that almost all key intellectual, political, and theological questions have been cast in their terms. From the 1730s onward, such questions were increasingly connected to the idea of the "man-machine" – the mechanical android. This was not least due to Jacques de Vaucanson's work from the 1730s, and the work of other artisans in the following decades, whose mechanical androids quickly became (...) well-known and provided actual manifestations of man-machines. Eighteenth-century mechanical androids were more sophisticated in regard to mechanical complexity and craftsmanship than those of... (shrink)

Governments, or at least the clever ones among them, are aware of the factors guiding business activities. In the course of adopting and enforcing economic legislation, they seek to attract business activities in order to increase national income, generate employment opportunities, and, very generally, please voters. Hence economic law may be considered an economic good, as suggested by the title of this book. That function, which most rules of economic law have in the competition of systems, was strengthened by the (...) worldwide liberalization of trade. Today, it is of greater significance than ever before. Lawyers, economists, academics, and practitioners, from inside and outside Germany, have taken a look at the facts and have discussed approaches to conceptualizing them. The resulting 30 essays, collected in this volume, contribute to the interpretation of existing, and the making of new, economic law. (shrink)
