Last Wednesday, Cheryl posted an interesting analysis of the nature vs. nurture debate that has plagued the social and biological sciences since their emergence. More and more research, from both disciplinary areas, is accumulating to overturn this simplistic dichotomy. Rather than thinking of ourselves as purely determined by our body chemistry and structure OR by our social environment, it is useful to think of ourselves as what Donna Haraway terms “material-semiotic” entities—that is, as unique combinations of natural and cultural elements. This way of theorizing the relationship between nature and culture—or rather, the mutual and continuing construction of nature and culture—is given to us by critical science studies scholars. By thinking, as Haraway does, in terms of “naturecultures,” we escape the nature/nurture divide, merging the two inseparably. What we call “nature” and “culture”/“nurture” are actually mutually constituted. (more…)

Nature AND Nurture: Undermining Inequalities with Sociology and Biology

In the most recent issue of Sociology Compass, Lisa Wade contributed an article, “The New Science of Sex Difference,” about the relationship between biology and social identities and inequalities. The debate about socialization usually boils down to two seemingly opposed positions: nature versus nurture. Historically, biologists, and other fans of the life sciences, contended that natural forces in the body, like hormones, genes, and brains, determine the development of an individual. On the other hand, sociologists refute the claim that human behavior and identity can be reduced to biological phenomena; instead, our social environment, and how we are nurtured within that environment, constrain and enable our actions, life outcomes, and sense of self.

Yet, Wade cautions against this false dichotomy. Many biologists and sociologists now recognize the importance of social structures and experiences on the actual fabric of the body. That is, the issue should not be nature versus nature, but instead both nature and nurture. Wade points to numerous scientific and sociological studies that begin to bridge the gap between two previously polarized sides: these scholars show how our hormones, our brains, and even our genes are structured, and at times restructured, by our social experiences and encounters.

Girls Who Code: Gender, STEM, and the Importance of High School Intervention

Last fall, like any good teacher of the sociology of gender, I introduced my class to the patterns of gender bias in STEM fields (science, technology, engineering, and mathematics). My students were not shocked by the observation that few women enter these fields in college. In fact, one of my students raised her hand and explained the bias first hand. She was a computer science major, enrolled in a computer science course held in the same lecture hall in the time block before our class. She would see the composition of the classroom change as one course ended and the other began: mostly men would leave the computer science class, and then relatively equal numbers of men and women entered the sociology of gender class. My class discussed many ways to eliminate the gender bias in STEM fields, including high school level interventions to enable girls to excel in these majors. This is why I was so excited to open the New York Times this week and read an article about Girls Who Code, an organization that teaches computer code to high school girls in order to prepare them for a college major in computer science.

The Good and Bad News about HIV Infections

Source: CDC

Source: CDC

This week, great news emerged out of Mississippi: an infant, previously infected with HIV, has been cured of the virus. This development indicates promise for the future. We have now entered an era with the possibility of curing a once incurable disease. This is certainly a time to celebrate the progress of modern medicine and its ability to save the lives of millions of people. However, alongside this great news, the Center for Disease Control (CDC) has released new data on the rates of new HIV infections among adults and adolescents in the United States. This data reminds us that we still have a long way to go to eradicate this infection; many, many men and women are diagnosed with HIV every day.

Specifically, the CDC reports that southern states, like Texas, Florida, Louisiana, Alabama, Mississippi, North Carolina, South Carolina, and Georgia, have some of the highest rates of new HIV infection among adults and adolescents in the United States. The rates of diagnoses in these states is anywhere from 20.0 to 177.9 new HIV infections for every 100,000 people in the population. While some northern states, like New York and New Jersey, have comparable numbers, the greatest concentration of these astoundingly high rates can be found in the southern half of the United States. Something is clearly going on here.

Some analysts point to the lack of complete and factual sexual education in the disproportionately affected states. None of these southern states require comprehensive and accurate HIV/AIDS education. Two states, Florida and Texas, do not require any sexual education in public schools. While the CDC did not statistically test the relationship between comprehensive sex education and rates of new HIV infection, the link between the two seems pretty obvious: if students learn how to prevent the spread of the disease through safe sex practices, their risk of infection should decrease.

Why, then, are states still resistant to comprehensive sex education in their schools? We have moved past the days when the federal government espoused an abstinence-only agenda and tied education funds to states’ adherence to the “no sex outside of heterosexual marriage” motto. Since President Obama has entered office, an equal amount of funds for comprehensive sex education that teaches about safe sex practices, including abstinence, and about sexualities other than heterosexuality is available for states wishing to educate their students. Yet, some states, like Florida and Texas, do not take advantage of this funding.

Sociologically, we know that a fear of adolescent sexuality underlies many of the concerns about sexual education in public schools. In my first Sociology Lens post back in 2012, I described some of these fears by drawing on Jessica Field’s Sociology Compass article, Sexuality Education in the United States: Shared Cultural Ideas Across the Political Divide. In this article, Fields insightfully points out that regardless of political position on the issue of sex education, most people are motivated by the desire to regulate an out-of-control or dangerous adolescent sexuality. Fields’ argument continues to be relevant today; the new statistics on rates of HIV infection seem to be an unfortunate consequence of these publicfears.

While I am very optimistic about the health of the Mississippi baby, I am hesitant to say that this medical progress is enough. Can the same procedure be used to cure older individuals infected with HIV? Will the procedure be widely available at a reasonable rate? In the absence of these answers, we need to remember that one of the ways to eradicate HIV is to spread knowledge about safe sex practices so that new infections decrease. In addition to new medicine, we need to continue to raise awareness about safe sex and disease prevention through publically funded education.

Gender, Sexuality, and the HPV Vaccine: Part 2

 

Source: Consumer Reports

In mid-October, I posted about a recent study that assesses the relationship between rates of sexual activity-related outcomes and the Human Papillomavirus (HPV) vaccination. The researchers found that injection of the vaccine is not associated with elevated rates of sexual activity-related outcomes in young girls, specifically pregnancy, contraceptive counseling, and sexually transmitted infection testing and diagnosis. While removing the stigma around the vaccine will help girls and women, I asked why the vaccine continues to be associated with women, even though Gardasil is approved for men, too.

Gardasil, the vaccine that prevents 70% of HPV-related cervical cancers and 90% of genital warts, was first approved for use in women by the Food and Drug Administration (FDA) in 2006. Soon after, the Center for Disease Control (CDC) recommended that the vaccine become a part of the normal vaccination schedule for girls. In 2009, the FDA approved the vaccine for men, but the CDC initially did not recommend the vaccine as part of the normal vaccination schedule for boys (the CDC changed its mind in 2011, though). In this next post, I will go into more depth about the research guiding the CDC’s initial decision and suggest that the guidelines were only possible when assuming a heteronormative model of transmission, as well as women’s general responsibility for reproductive health. Both of these assumptions continue to perpetuate the link between the vaccine and women.

Gender Bias in Mentoring Practices

Source: Forbes.com

In a recent article in the Proceedings of the National Academy of Sciences in the United States, a group of scholars reported on the continued gender discrimination in the hard sciences. The researchers asked 127 male and female professors in biology, chemistry, and physics to rate male and female job candidates for a position in their labs. The portfolios of the candidates were exactly the same, but half used the name, “Jennifer,” and the other half, “John.” The professors rated the male candidates as more competent and hireable; they also decided on higher starting salaries for the men.

The findings from this study are disturbing, but not so surprising. Decades of research documents higher salaries and more job opportunities for men in most careers and professions. What surprised me most about this study was that, in addition to rating male candidates as more competent and hireable, the professors reported that they would be less willing to mentor the female candidates. Since mentoring often goes hand in hand with job opportunities, achievements, and salaries, perhaps I should not be so shocked. Still, this finding from the study sits uneasily with me.

As a graduate student, I know the importance of a good mentor (fortunately, I have benefited from great mentoring at every step of my graduate and undergraduate career). In her Sociology Compass article, Feminist Mentoring and Female Graduate Student Success: Challenging Gender Inequality in Higher Education, Priya Dua explains the many benefits of good mentoring, especially for women: female students with mentors are more likely to be involved in professional activities and are more productive than those without mentors; the status of female student mentees increases with the encouragement of faculty mentors; female students learn how to balance the expectations of academia and other aspects of life (including family responsibilities) when they have a supportive role model. These are all great reasons why the mentor/mentee relationship between faculty member and student is so important.

The Social Construction of Scientific Knowledge: The New AAP Policy on Male Circumcision

The American Academy of Pediatrics (AAP) recently released a revised policy statement regarding male circumcision. Unlike previous policies on the issue, this one got a lot of media attention, probably because male circumcision itself has been in the news more than usual. The past few years have seen increasing mobilization against male circumcision (for example, intactivists (the term activists fighting for genital integrity have given themselves) tried to ban the practice in the city of San Francisco last year, though the attempt was unsuccessful). And the surgery gained some global attention this year after a German court ruled that it constituted grievous bodily harm against a minor. Many national governments and religious groups/leaders spoke out against the court ruling, the court’s decision has caused many to think a bit more about neonatal circumcision.

Progressing from game theory to agent based modelling to simulate social emergence

This article discusses some of the fundamental flaws in game theory and discusses agent based modelling as a successor to model social emergence.

Axelrod (1984) made a major contribution to Game Theory in his book “Evolution of Cooperation” but thirteen years later he, dissatisfied with game theory, moves onto agent based modelling to rework his view of cooperation in his book in 1997 “The complexity of Cooperation: Agent-based Models of Competition and Collaboration”.  In a similar move, the Santa Fe Institute in the US was established in 1984 to grapple with complex social issues and used agent based modelling amongst other techniques to “collaborate across disciplines, merging ideas and principles of many fields — from physics, mathematics, and biology to the social sciences and the humanities — in pursuit of creative insights that improve our world”.  Additionally, the EU acknowledges the failure of traditional economics so adopts agent based modelling.

Agent based modelling captures the interaction between agents to simulate emergence whether at the physical or social level. NetLogo  provides an extensive library of simulations of both physical and social emergence that shows the diversity of application of agent based modelling.  These sample simulations can be readily tailored to meet the needs of social scientists.  The software is free and there is a thriving enthusiastic community support group.

Why is there a move by a prominent game theorist, the Santa Fe Institute and the EU to agent based modelling?  The article Game Theory as Dogma by Professor Kay (2005) discusses ample reasons to search for alternative techniques to model competition and collaboration  and emergence in general.  For instance.

The trouble with game theory is that it can explain everything. If a bank president was standing in the street and lighting his pants on fire, some game theorist would explain it as rational. (Kay 2005, p. 12) (more…)

Sustainability, social progress, environmental protection, economic growth and energy

Sustainability, social progress, environmental protection, economic growth and energy are discussed using the sustainability framework in Figure 1, where sustainability is at the confluence of social progress, environmental protection and economic growth.

There are designs being made toward Ecological Civilization and welcome moves to address the shortcomings of GDP in Completing the picture – environmental accounting in practice by the Australian Bureau of Statistics .  Extending the national accounts to include degradation of natural resources makes a measurable target for politicians to focus on rather than purely GDP.    However, there are problems when social progress is overlooked in the move toward more environmental protection.

Rosie O’Donnell Reminds Us About Women’s Heart Health

Source: http://www.realage.com/womens-health/hidden-heart-attack-signs-in-women

Last week, media sources reported that Rosie O’Donnell had a heart attack. Though Rosie explained that she did “google” her symptoms, she did not believe she was having a heart attack and never called 911. Like many women, Rosie explained that she did not know enough about female heart issues, specifically identifying the problem and getting immediate medical attention. Rosie hopes she can use her fame and platform to raise awareness about heart attacks and issues in women.

While Rosie lived to tell her story, many women don’t. Researchers estimate that 1 in 4 women in the United States die of heart diseases every year. And, like Rosie mentions, many women don’t know their suffering from a heart attack until it is too late. Many of us know the ways in which heart attacks appear in men: pain in the left arm, pains in the chest. But studies suggest that women may not have the benefit of these tell-tale signs. Notably, women are less likely to present with chest pains when suffering a heart attack.  If heart diseases are common in women, why do so many women lack potentially lifesaving knowledge about the signs and symptoms of a heart attack?

At least part of the answer is historical. There was a time when women’s cardiovascular health was understudied and even ignored by some in the medical community. In the late 1980s, feminists in and around the field of medicine demonstrated that our knowledge about certain health issues emerged from research on the male body. For example, several studies on blood pressure, heart issues, and the “normal” functions of human aging were based almost exclusively on findings from the male population. Now, medical researchers recognize the importance of studying these same issues in the female population, but still, the research for women is years behind that of men.

Though the medical community now recognizes the importance of studying a broader spectrum of diseases in women, it seems that when we think of “women’s health,” we think about issues specific to the female anatomy. Though women may be afflicted with other major medical concerns, a huge amount of money and time is devoted to maintaining the healthy development and stability of the distinctively “female” parts of the body.  Organizations, like Susan G. Komen for the Cure, draw substantial resources to find a cure for breast cancer. Pharmaceutical companies develop vaccines, like Gardasil, targeted at preventing cervical cancer. Physicians and gynecologists recommend that women have their breasts and reproductive organs examined every year (though some have loosened up on this recommended frequency). Yet, heart disease, one of the largest “killers” of women, gets one day of awareness, Wear Red Day.

Don’t get me wrong. All of these developments are good for women. The emphasis on reproductive and breast issues has surely helped many women, who may have died from a disease of these organs or who wish to expand their reproductive options. But this obsession may have left other common problems unexamined and women without the resources or knowledge to combat them. The fact that many women do not know about the signs of a heart attack is evidence of this.

I don’t think that this should mean a decrease in research and outreach for women specific health issues. This needs to continue. Instead, we need an equal amount of research on other issues, as well as public health campaigns informing women of other risks to their health.
