Evolution has shaped all living organisms on Earth, although many details of this process are shrouded in time. However, it is possible to see, with one's own eyes, evolution as it happens by performing experiments in defined laboratory conditions with microbes that have suitably fast generations. The longest‐running microbial evolution experiment was started in 1988, at which time twelve populations were founded by the same strain ofEscherichia coli. Since then, the populations have been serially propagated and have evolved for tens (...) of thousands of generations in the same environment. The populations show numerous parallel phenotypic changes, and such parallelism is a hallmark of adaptive evolution. Many genetic targets of natural selection have been identified, revealing a high level of genetic parallelism as well. Beneficial mutations affect all levels of gene regulation in the cells including individual genes and operons all the way to global regulatory networks. Of particular interest, two highly interconnected networks—governing DNA superhelicity and the stringent response—have been demonstrated to be deeply involved in the phenotypic and genetic adaptation of these experimental populations.

Law provides a rich language for thinking about bioethical issues and is a tool for action as well as talk. But the language of the law, often inapt, regularly fails to achieve its desired effect.

In the deviance literature, sexual assaults at work have not been given the sustained attention that harm to property or violation of production guidelines has received. This omission suggests that sexual harassment is considered normative and that when women fail to accommodate this reality, it is the survivor rather than the perpetrator who is considered deviant. This article reports on 64 cases of attempted or completed rape in a sample of heterosexual and lesbian women workers in a wide range of (...) occupations. Two atypical responses, quitting the job or filing a complaint as a result of a workplace sexual assault, highlight the process by which informal deviance defining occurs in everyday interactions at work.

In America today, public policy governing an increasing number of social issues is made through the judicial enforcement of constitutional rights. Cruzan raised the question whether policy regarding the withdrawal of medical care from incompetent patients is to be handled similarly. This essay argues that privacy-rights doctrine provides a poor basis for constructing public policy in this area. It suggests that the Court has been unable to articulate a convincing basis for privacy rights and that the basis the Court seems (...) to assume poorly fits many circumstances to which it is applied. The essay further contends that the Court has been unable to describe a persuasive method of analyzing the state interests that are at stake in privacy cases and to accommodate those interests in a reasonable way. The essay concludes that these are issues as to which policy is better formed through a political, not judicial, process.

Almost nobody favors long consent forms for prospective research subjects. Almost everybody thinks they interfere with informed consent’s purpose—good decisions. Nevertheless, almost everybody believes consent forms have long been getting longer. Years ago, Paul Appelbaum lamented the “tendency to cram ever more information into consent forms.”1 Weeks ago, Ilene Albala and her colleagues (one of them Appelbaum) reported in IRB: Ethics & Human Research that the length of one institutional review board’s forms “increased roughly linearly by an average of 1.5 (...) pages per decade. In the 1970s, the average consent form was less than one page long and often only a paragraph or two, but by the mid-1990s the .. (shrink)

Book reviewed in this article: Rights Talk: The Impoverishment of Political Discourse. By Mary Ann Glendon.

Wicked problems are tricky to solve because of their many interconnected components and a lack of any single optimal solution. At the science–policy interface, all problems can look wicked: research exposes the complexity that is relevant to designing, executing and implementing policy fit for ambitious human needs. Expertise in philosophical research can help to navigate that complexity.

Eye movements during false-belief tasks can reveal an individual's capacity to implicitly monitor others' mental states (theory of mind - ToM). It has been suggested, based on the results of a single-trial-experiment, that this ability is impaired in those with a high-functioning autism spectrum disorder (ASD), despite neurotypical-like performance on explicit ToM measures. However, given there are known attention differences and visual hypersensitivities in ASD it is important to establish whether such impairments are evident over time. In addition, investigating implicit (...) ToM using a repeated trial approach allows an assessment of whether learning processes can reduce the ASD impairment in this ability, as is the case with explicit ToM. Here we investigated the temporal profile of implicit ToM in individuals with ASD and a control group. Despite similar performance on explicit ToM measures, ASD-diagnosed individuals showed no evidence of implicit false-belief tracking even over a one-hour period and many trials, whereas control participants did. These findings demonstrate that the systems involved in implicit and explicit ToM are distinct and hint that impaired implicit false-belief tracking may play an important role in ASD. Further, they indicate that learning processes do not alleviate this impairment across the presentation of multiple trials. (shrink)

James Fitzjames Stephen is remembered as a judge, legal historian, and the author of Liberty, Equality, Fraternity, a reply to J. S. Mill's late works. He is less well remembered for his journalism, though it earned him a reputation among his contemporaries as one of the most trenchant writers on topics ranging across the social, religious, political, moral, and philosophical questions debated in his time. It was largely in his journalistic writing that Stephen set forth his views on these questions. (...) Despite such a reputation, however, only a small proportion of this writing was collected during his lifetime, and very little has been republished since his death.Selected Writings of James Fitzjames Stephen: On Society, Religion, and Government includes thirty-five essays expressing Stephen's views on the questions of his day, which have not lost their interest in ours. He wrote at a time when much of the finest writing in English was published in periodicals, often anonymously. The essays in this volume are drawn mostly from Stephen's unsigned contributions to the Saturday Review, with additions, both signed and unsigned, from other periodicals, extending from the 1850s to the 1880s.

Let us look to America, not in order to make a servile copy of the institutions that she has established, but to gain a clearer view of the polity that will be the best for us; let us look there less to find examples than instruction; let us borrow from her the principles, rather than the details, of her laws. The laws of the French republic may be, and ought to be in many cases, different from those which govern the (...) United States; but the principles on which the American constitutions rest, those principles of order, of the balance of powers, of true liberty, of deep and sincere respect for right, are indispensable to all republics; they ought to be common to all …. —Alexis de Tocqueville Democracy in America.

In pursuit of the dream that patients' exercise of autonomy could extend beyond their span of competence, living wills have passed from controversy to conventional wisdom, to widely promoted policy. But the policy has not produced results, and should be abandoned.

Corporations and investors are responding to recent major ethical scandals with increased attention to the social impacts of business operations. In turn, business colleges and their international accrediting body are increasing their efforts to make students more aware of the social context of corporate activity. Business education literature lacks data on student attitudes toward such education. This study found that postscandal business students, particularly women, are indeed interested in it. Their interest is positively related to their past donation, volunteerism, and (...) non-profit organization membership activities, whether limited or extensive. Some evidence supports the proposition that education can modify internal principles over time. We offer suggestions for classroom and program uses of these findings in hopes of enriching the vision of future business managers. (shrink)
