Blogs Comment On Ryan-DeLauro Bill, Sex Education Funding, State Reproductive Health Legislation
The following summarizes selected women"s health-related blog entries.~ "A Taxing Problem," Jessica Arons, Huffington Post blogs: The five Democrats who last week sent a letter to House Speaker Nancy Pelosi (D-Calif.) "suggesting a "common ground" solution to the abortion "roadblock" in health care reform" should be "applauded" for keeping the debate"s focus on covering the uninsured and "for being unwilling to sacrifice health care reform on the altar of abortion politics," writes Jessica Arons, director of the Women"s Health & Rights Program at the Center for American Progress. Arons adds that while the proposal, led by antiabortion-rights Rep. Tim Ryan (D-Ohio), "is in welcome contrast to the stonewalling and ultimatums coming from Rep. Bart Stupak (D-Mich.) and his allies," it is "based on a misguided and attenuated definition of government spending, and it conflicts with what Americans want and expect from health care reform." She continues that the "suggestion that a health plan might offer abortion coverage, and it might be used by someone, who might have paid a lower premium than someone else, because the government might have helped pay their premium is a horrible reason for Congress to carve out an explicit exception to a bill that is otherwise entirely silent on coverage options." Taxpayers "do not have the right to specify how their tax money should be spent," she writes, adding, "I understand why people would want to withhold their taxes from purposes they oppose, but our system does not -- nor should it -- work that way" (Arons, Huffington Post blogs, 7/30).~ "The Breakup of the Pro-Life Movement," Cristina Page, Birth Control Watch: Rep. Ryan is "in many ways a typical pro-life American" who opposes abortion rights and, "like most pro-life Americans, ... supports every effort to prevent the need for it," including contraception, Page writes. However, because of his support for contraception and sponsorship of the "Preventing Unintended Pregnancies, Reducing the Need for Abortion and Supporting Parents Act," Ryan was "banished" from the board of Democrats for Life of America, Page writes, adding that antiabortion-rights publications have "taken to qualifying his pro-life status as "allegedly" pro-life or referring to him as someone "who claims to be" pro-life." The bill, also known as the Ryan-DeLauro bill, would increase funding for contraception, and support comprehensive sex education and services for women who choose to carry unintended pregnancies to term, Page writes. She notes that the bill is supported by "many prominent pro-life individuals" and groups that support abortion rights, though "[n]ot one leading pro-life group signed onto the bill." Page writes, "Pro-life Americans favor expanding access to contraception because of the undeniable pro-life results," adding, "Unintended pregnancy is the root cause of abortion. We know when used properly, contraception works." It is "time for the disagreement over contraception to be addressed by the pro-life community at large," she writes, adding, "We will have no chance of making a real impact on unintended pregnancy and abortion rates without dramatic, informed strategies on prevention" (Page, Birth Control Watch, 7/28).~ "Senate Subcommittee: Ab-Only Out, Syringe Ban Still In; Advocates Hope for Further Changes in Conference Committee," Jodi Jacobson, RH Reality Check: The spending bill approved yesterday by the Senate Appropriations Committee "zeroes out funding" for the Community-Based Abstinence Education program, which has "for years [been] the main of support for now-discredited abstinence-only programs," Jacobson writes. The "elimination of these funds parallels similar action in the House, ... so unless amendments are proposed, accepted and passed during either the full committee vote or on the Senate floor, this bill spells "the end of abstinence-only programs as we know them," said one advocate, "at least for this year,"" Jacobson writes. The Senate version of the bill allocate

Mate Selection: How Does She Know He'll Take Care Of The Kids

Throughout the animal kingdom brilliant colors or elaborate behavioral displays serve as "advertisements" for the process of attracting mates. But, what do the ads promise and is there truth in advertizing? Researchers at Yale theorize that when males must provide care for the survival of their offspring, the males" "advertisements" will always be honest - and they may devote more of their energy to caring for their offspring than to attracting females. The idea that males try to advertise their best qualities to attract females for mating isn"t a new one, nor is the idea that they might be deceptive in what they are advertising. According to Natasha Kelly, a graduate student in ecology and evolutionary biology and lead author, their new model more closely predicts the requirement for honesty in advertizing as a function of the male"s suitability for parenting. The peacock"s tail, or the primping and posturing guy in a bar are "advertisements" or mating displays that take substantial energy to maintain. When a male"s energy is heavily focused on keeping up his appearance, he may have little energy to devote to caring for offspring. But that may be ok - he may not need to tend to the kids. Previous research suggested that, under certain circumstances, males could be dishonest about their parenting skills and still have high reproductive success. This new model, appearing June 11 online before print in the Proceedings of the Royal Society B, examines the reliability of males" mating signals when they must care for offspring - an aspect that was missing in earlier studies. There are many species where males should, but do not have to, provide parental care -where females pick up the slack. These researchers focuses on those species where females can"t pick up the slack and males pay the price of not providing care. "This new work shows that when males can not escape the cost of their own failure to provide care, their advertisements will always be reliable," said principal investigator Suzanne Alonzo, assistant professor of ecology and evolutionary biology at Yale. "The qualifier in this case is where males are obligated to provide care," said Kelly. "In that case, the quiet guy in the corner might be the better choice for fatherhood." The National Science Foundation and Yale University funded this research.
