A new bioassay for comparing the palatability to avian predators of monarch butterflies reared on various asclepiadaceous food plants containing cardiac glycosides indicates a palatability spectrum. The monarchs reared on one plant species are six times as emetic as those fed another, while those raised on an asclepiad which lacks cardiac glycosides are not emetic at all.
A large body of evidence has documented the effectiveness of mass-media communication programs in increasing family planning use and changing reproductive behavior. But the potential impact of these programs on the mediating role of gender norms has not been systematically assessed in Nigeria. Regionally representative cross-sectional end line data collected for the evaluation of a long-running entertainment-education radio serial drama program aired in northern Nigeria are examined for program effects on both reproductive and gender outcomes as well as the relative effect of gender on reproductive outcomes. The drama was popular, with 70% of the sample listening weekly. Results show that the drama positively impacted both sets of outcomes especially the reproductive outcomes. Results further indicate a strong relative effect of gender on reproductive issues.
Population has waxed and waned as an issue of public consciousness and action by policymakers. The issue is on the ascendancy again in part because of climate change and food crises caused by escalating food prices, the energy crisis and growing shortages of fresh water. In the face of these problems, attempts of some governments to stimulate higher birth rates, over concern with aging populations, are misplaced and counterproductive. Vallentyne's longneglected 'demotechnic index' holds new promise for considering both population numbers and consumption rates when evaluating the impact of humans on the environment. Its appearance in publication now is all the more important because of the failure of political leaders to act on the numerous expert warnings issued over several decades regarding the impact of human population growth and expanding utilization of resources. Thus, the world community needs to act urgently to utilize the demotechnic index of Jack Vallentyne to look holistically at ways to achieve a sustainable society.
In 1994, the Programme of Action of the International Conference on Population and Development was adopted. The Programme conveys anthropocentric sensibilities when discussing the idea of sustainable development. Moreover, the Programme has largely been interpreted in such a way that it fails to hold the goal of ending population growth at the same level of esteem as the goal of ensuring reproductive health and rights. Despite some unfavorable outcomes, the Programme’s orientation around gender equality is to be celebrated. In section 11.23, the Programme highlights a key tactic to help achieve gender equality: effective use of the entertainment media, including radio and television soap operas and drama. Since 1998, Population Media Center has successfully used mission-driven entertainment to confront the most powerful drivers of ongoing rapid population growth: the social norms, attitudes and behaviors related to the status of women in various societies around the world; misinformation about contraception and cultural barriers to its use (such as male opposition); and perceived norms with regard to ideal family size.
is dating the prom queen, Vanessa de la Cruz, and Jessie does not think she has a chance. However, Vanessa leaves the prom to have sex in the back of a car with another student, and Jacob finds out.
