Creating Critical Viewers

This essay is a personal reflection on the implementation of Creating Critical Viewers, a national media literacy program sponsored by the National Academy of Television Arts and Sciences (NATAS), an industry association, in 1995. The television industry’s decision to develop a media literacy curriculum in the 1990s was a powerful statement by certain broadcasters to take seriously the ethical and social questions being raised about the impact of their work and to learn how to address those questions through education

Adaptations to adoptive parenthood.

This project studied the parental self-picture of adopters, processes of adjustment to adoption, assessment of adjustment, and adopters’ attitudes regarding racially mixed adoptions. The adopters had been unable to procreate their families, and in this respect were different from natural parents. Some adopters might be conscious of this difference, while others might- feel that the adoptive family approximates the natural. These feelings of “sameness” or “difference” were thought to affect the adopters’ adaptability to adoption

Exercise and gene expression: physiological regulation of the human genome through physical activity

The current human genome was moulded and refined through generations of time. We propose that the basic framework for physiologic gene regulation was selected during an era of obligatory physical activity, as the survival of our Late Palaeolithic (50 000–10 000 BC) ancestors depended on hunting and gathering. A sedentary lifestyle in such an environment probably meant elimination of that individual organism. The phenotype of the present day Homo sapiens genome is much different from that of our ancient ancestors, primarily as a consequence of expressing evolutionarily programmed Late Palaeolithic genes in an environment that is predominantly sedentary. In this sense, our current genome is maladapted, resulting in abnormal gene expression, which in turn frequently manifests itself as clinically overt disease. We speculate that some of these genes still play a role in survival by causing premature death from chronic diseases produced by physical inactivity. We also contend that the current scientific evidence supports the notion that disruptions in cellular homeostasis are diminished in magnitude in physically active individuals compared with sedentary individuals due to the natural selection of gene expression that supports the physically active lifestyle displayed by our ancestors. We speculate that genes evolved with the expectation of requiring a certain threshold of physical activity for normal physiologic gene expression, and thus habitual exercise in sedentary cultures restores perturbed homeostatic mechanisms towards the normal physiological range of the Palaeolithic Homo sapiens. This hypothesis allows us to ask the question of whether normal physiological values change as a result of becoming sedentary. In summary, in sedentary cultures, daily physical activity normalizes gene expression towards patterns established to maintain the survival in the Late Palaeolithic era
