To many, genomics is merely exploitable technology for the leviathan of biotechnology. This is both shallow and short sighted. Genomics is applied knowledge based on profound and evolving science about how living things develop, how healthy or sick we are, and what our future will be like. In health care, genomics technologies are disruptive yet potentially cost-effective because they enable primary prevention, the antidote to runaway costs and declining productivity. The challenges to integration are great, however, and many bioethical and social-policy implications are alarming. Because it is poorly understood today, we must debate genomics vigorously if we are to act wisely. Public policy must lead.  相似文献

Feminist theory needs a constructivist account of biological sex for at least two reasons. The first is that as long as female and male are the only two sexes that are taken for granted, being cisgender, heterosexual, and preferably a parent will be the norm, and being intersexed, transgender, bi- or homosexual, infertile or voluntarily childless will be deemed failure. The second is the fact that, usually, sex and gender come together in the way that is expected, i.e. the fact that most females are women and most males are men needs to be explained. This paper provides a constructivist theory of sex, which is that the sex categories depend on norms of reproduction. I argue that, because the sex categories are defined according to the two functions or causal roles in reproduction, and biological function is a teleological concept involving purposes, goals, and values, female and male are normative categories. As there are no norms or values in nature, normative categories are social constructions; hence, female and male are not natural but social categories. Once we understand that biological normativity is social, biological norms of heterosexuality, fertility, and so on are no longer incontestable. In addition, as many gender norms also concern reproduction—socially mediated reproduction—this simple theory of sex explains the common confluence of sex and gender.  相似文献

Bullying, a form of interpersonal violence, has emerged in the 21st century as an important public health issue. Bullying during childhood and adolescence is a common problem and occurs almost universally. It may be viewed on a continuum as a relationship problem in which power and aggression are inflicted on a vulnerable person to cause distress. However, teasing and bullying can turn deadly. A deeply troubled youth, after years of chronic bullying, may decide he has no alternative but suicide. The Daniel Scruggs case is one such example. Alternatively, the troubled youth may be attracted to the violent hero presented in the media that demonstrates his power via weapons as in the cases of school shootings.

Why does bullying continue? Some of the problem is the belief that bullying is simply a part of growing up; adults who believe this are often unwilling to intervene. Bullies are not always easy to identify, as they are adept at concealing bullying behavior. Anti-bullying school programs have shown promise in reducing unacceptable behaviors. The next step is to educate teachers, law enforcement, and mental health staff members to identify the red flags of teasing and bullying that indicate an at-risk youth for either suicide or homicide.  相似文献

Forensic science professionals are routinely exposed to potentially traumatizing evidence. This study aimed to estimate the prevalence of occupational posttraumatic stress disorder (PTSD) among forensic science professionals, identify job-related correlates of PTSD symptoms, and examine the role of social support in mitigating PTSD symptomology. In response to recruitment through the American Academy of Forensic Sciences, the American Society of Crime Laboratory Directors, and Evidence Technology Magazine, 449 forensic science professionals participated in the current study. Results found that 73.5% (n = 330) of the overall sample experienced at least one work-related traumatic event consistent with meeting Criterion A for PTSD, and these rates were higher for field-based respondents (n = 203, 87.9%). The prevalence of past-month provisional PTSD was 21.6% for the full sample. Disaggregated PTSD rates were 29.0% and 14.5% for field-based and non-field-based respondents, respectively. These rates were 6- to 8-fold higher than the past-year prevalence of PTSD in the general US population, estimated to be 3.5%, and were found to be at least as high as those observed in prior epidemiological research with non-treatment seeking members of the US military deployed to war zones in Iraq and Afghanistan. Results further showed that social support was protective against PTSD symptomology. The high rates of occupational exposure to trauma and consequent PTSD symptomology observed in this large sample of forensic science professionals highlight the under-acknowledged psychological risks of these occupations and the need for enhanced attention to mental health resources for these professionals.  相似文献

Eight complete baboon carcasses were fed individually to two captive leopards. These experimental feedings generated two separate bone assemblages, one composed of those bone specimens not ingested by the leopards (i.e., the refuse assemblage), and one composed of those bone specimens ingested and subsequently voided by the leopards (i.e., the scat assemblage). The two assemblages are separable using measurements of skeletal part representation. Distinguishing characteristics of the assemblages are summarized and explained in relation to observations of leopard feeding behavior and intrinsic qualities of baboon postcranial bones (i.e., bulk bone mineral density, maximum length, volume and cross-sectional area). Because baboons and humans share the fundamental primate body plan, these baboon carcasses approximate human cadavers ravaged by large felids. Thus, our results can inform death scene investigators about the expected human body part representation in large felid feeding residues versus those expected in regurgitations and feces. Since different body parts have different body-identification potentials, knowing these expected differences in body part representation is particularly valuable in forensic settings.  相似文献

Postcards are an important resource that has been largely overlooked in mainstream research on historical events, political attitudes, perceptions, propaganda, and communication. Accordingly, this article expands the relevance of the postcard from social artifact to historical document embodying social and political messages. In particular, the article examines the images and representations used in cartographic postcards during and after the Russo-Japanese War (1904–1905). Not only is this relevant to the study of political propaganda, but also for the study of historic media, popular consumption of political messaging, and as an additional tool with which to study the history of international politics and communication. The political history leading up to the outbreak of the Russo-Japanese War is briefly covered. Images of cartographic postcards are examined in context of the conflict, with the goal of gaining a greater appreciation for postcards as a form of early “soft news” visual mass media. As such, this is a means by which imperial attitudes and public opinion were shaped. Recommendations are made to broaden the use of postcards as primary documents, especially as these cards are enjoying an online renaissance (e.g., collecting, displaying, discussing). They are valuable in augmenting a variety of research agendas and are fruitful for the study of early modern mass media, social history, public discourse, and political messaging with regard to soft news and public opinion.  相似文献
