Cellular dedifferentiation is an important developmental response to perturbations in morphogenesis. In the cellular slime mold Dictyostelium discoideum this process gives cells the flexibility, when multicellular development is disrupted, to respond to nutrients and reinitiate vegetative growth. Recent studies in D. discoideum described by Soll and colleagues(1) show that genes previously thought to be expressed only during spore germination are also expressed during induced dedifferentiation, suggesting that similar molecular mechanisms are involved in these two developmental processes. It should now be (...) possible to determine whether the developmental programs that control dedifferentiation during spore germination also control conversion of cell types in the multicellular organism.

In lieu of an abstract, here is a brief excerpt of the content:14 Feminist Studies 46, no. 1. © 2020 by Feminist Studies, Inc. Melissa Oliver-Powell Beyond the Spectacle of Suffering: Agnès Varda’s L’Unechante,l’autrepas and Rewriting the Subject of Abortion in France In the spring of 1971, three years after the revolutionary fervor of May 1968 in France, 343 women put their names to a courageous manifesto announcing that they were criminals of a particularly gendered nature. The authors of (...) Manifeste des 343 (Manifesto of the 343) comprised a large group of culturally eminent French women and activists declaring that they had all illegally undergone abortions, which at this point, despite growing decriminalization throughout much of Western Europe, were still outlawed within their republic. Though many of the revolutionary fires had now eased to embers, French feminists demonstrated that reproductive rights were still a vital and unresolved topic of social justice. Including names as weighty as Simone de Beauvoir, Jeanne Moreau, and Catherine Deneuve, the manifesto brought together exceptional women from the fields of academia, law, theater, film and literature, alongside grassroots activists. Their action was a bold challenge to the French authorities, daring them to arrest some of the country’s brightest thinkers and cultural innovators under a law the signatories felt was deeply unjust, sexist, and antithetical to the values of individual liberty and citizenship. It was a case of those with the broadest shoulders weaponizing their privilege to present a robust front line in the wider struggle for women’s rights. One of the signatories was filmmaker Agnès Varda. Her name, like those of several others on the list, demonstrates the symbiosis between Melissa Oliver-Powell 15 cultural production and gender politics that has often characterized French feminist thought. From the multidisciplinary writings of Beauvoir, to the novels of the écriture féminine movement, to the lyrical academic prose of Hélène Cixous, Luce Irigaray, Julia Kristeva, and others, French and Francophone feminist writers have tended to connect art and politics with a great deal of fluidity. As a committed activist and a filmmaker, Agnès Varda falls very much within this tradition, often adopting and developing feminist practices within her cinema. This article examines how Varda’s 1977 film, L’Une chante, l’autre pas (One Sings, The Other Doesn’t) interacts with and participates in the feminist political project of reproductive rights as well as the ongoing intellectual and moral debates over abortion taking place in France throughout the late 1960s and 1970s. I look particularly at the adversarial construction of abortion narratives within these debates and the location of victimhood therein. Within mainstream cultural representations in and beyond France, abortion is typically constructed as either a traumatic or a transgressive moment. The same is often true on either side of political and social debates on abortion, which have tended either to characterize the women who get abortions as irresponsible and amoral or as sympathetic victims in need of protection. Though the transgressive element persists, it is the interaction with representations of trauma that interests me here. In approaching discussions of gendered injustice, it is common for feminist writers and activists to leverage pathos as a rhetorical strategy. While suffering can be a highly effective and galvanizing expression of oppression, such discourses also run the risk of producing excessive depictions of victimhood, which can displace the capacity for action from the subject of hardship onto the privileged oppressor. This risk is particularly at stake within the cultural form of film, as its visuality and identificatory mechanics have the potential to spectacularize the female victim and make her relatable only through suffering. This was often the case in earlier French films that featured abortion such as Les Mauvaises rencontres (1955), Des gens sans importance (1956), Journal d’une femme en blanc (1965), and Une femme en blanc se révolte (1966), all of which made their subjects sympathetic by entwining them in long narratives of victimization ending in death or disgrace. This article looks at how Varda’s L’Une chante, l’autre pas disengages from the spectacle of suffering that so often characterizes representations of women’s experiences 16 Melissa Oliver-Powell and rejects the idea that abortion narratives must...

Based on the Mahlon Powell lectures given at Indiana University, this slim, well translated book is surprisingly rich and visionary in its pursuit of a metaphysics of language. Dufrenne, a phenomenologist, argues that positivistic and syntactical linguistics wrongly ignore the phenomenon of living speech, while formal logic, seeking to rid itself of its natural and intuitive origins, is necessarily rooted in them. What is needed is a phenomenology of human speech which would lead to a metaphysics of man's spoken (...) intercourse with the world. In the end, poetry has the last word.--A. B. D. (shrink)

Charting significant growth in science production over the 20th century in four European Union member states, this neo-institutional analysis describes the development and current state of universities and research institutes that bolster Europe’s position as a key region in global science. On-going internationalization and Europeanization of higher education and science has been accompanied by increasing competition as well as collaboration. Despite the policy goals to foster innovation and further expand research capacity, in cross-national and historical comparison neither the level of (...) R&D investments nor country size accounts completely for the differential growth of scientific productivity. Based on a comprehensive historical database from 1900 to 2010, this analysis uncovers both stable and dynamic patterns of production and productivity in Germany, France, Belgium, and Luxembourg. Measured in peer-reviewed research articles collected in Thomson Reuters’ Science Citation Index Expanded, which includes journals in the fields of Science, Technology, Engineering, Mathematics, and Health, we show the varying contributions of different organizational forms, especially research universities and research institutes. Comparing the institutionalization pathways that created the conditions necessary for continuous and strong growth in scientific productivity in the European center of global science emphasizes that the research university is the key organizational form across countries.

The editors of the new fragment of Gallus draw attention to line 6, ‘fecerunt carmina Musae’. They say ‘“fecerunt” is unusual in such a context, and to a Roman reader would inevitably suggest ; the Muses of Gallus provided craftsmanship as well as inspiration’. It is possible to be more precise: cf. Euphorion fr. 118 Powell.

Synthetic biology is an increasingly high-profile area of research that can be understood as encompassing three broad approaches towards the synthesis of living systems: DNA-based device construction, genome-driven cell engineering and protocell creation. Each approach is characterized by different aims, methods and constructs, in addition to a range of positions on intellectual property and regulatory regimes. We identify subtle but important differences between the schools in relation to their treatments of genetic determinism, cellular context and complexity. These distinctions tie into (...) two broader issues that define synthetic biology: the relationships between biology and engineering, and between synthesis and analysis. These themes also illuminate synthetic biology's connections to genetic and other forms of biological engineering, as well as to systems biology. We suggest that all these knowledge-making distinctions in synthetic biology raise fundamental questions about the nature of biological investigation and its relationship to the construction of biological components and systems.

The model of major transitions in evolution devised by Maynard Smith and Szathmáry has exerted tremendous influence over evolutionary theorists. Although MTE has been criticized for inconsistently combining different types of event, its ongoing appeal lies in depicting hierarchical increases in complexity by means of evolutionary transitions in individuality. In this paper, we consider the implications of major evolutionary events overlooked by MTE and its ETI-oriented successors, specifically the biological oxygenation of Earth, and the acquisitions of mitochondria and plastids. By (...) reflecting on these missed events, we reveal a central philosophical disagreement over the explanatory goals of major transitions theory that has yet to be made explicit in the literature. We go on to argue that this philosophical disagreement is only reinforced by Szathmáry’s recent revisions of MTE in the form of MTE 2.0. This finding motivates us to propose an alternative explanatory strategy: specifically, an interactionist metabolic perspective on major transitions. A metabolic framework not only avoids many of the criticisms that beset classic and revised MTE models, but also accommodates missing events and provides crucial explanatory components for standard major transitions. Although we do not provide a full-blown alternative theory and do not claim to achieve unity, we explain why foregrounding metabolism is crucial for any attempt to capture the major turning points in evolution, and why it does not lead to unmanageable pluralism.

John Sallis of Duquesne University has edited this fine collection of essays on Heidegger as a tribute to the latter on the occasion of his eightieth birthday. Some of the contributions are papers that were read at a Heidegger Symposium at Duquesne in October, 1966. There is a brief letter by Heidegger addressed to Arthur Schrynemakers, chairman of the Symposium, in which Heidegger submits a set of questions for the consideration of the Symposium participants. Sallis contributes an article which responds (...) to these questions. Zygmunt Adamczewski's contribution is a commentary and elaboration of some issues, e.g., the translation of Wesen, which he discussed personally with Heidegger in 1968. Edward Ballard gives a very clear-headed account of Heidegger's critique of science. There is an excellent account of the "Ereignis" by Theodore Kisiel and of "Time and Being" by André Schuwer. Other contributors include C. D. Keyes, Thomas Langan, Ralph Powell, Anna-Teresa Tymieniecka and John Wild. The volume is lacking in two respects. Except for a brief piece by Langan and for certain implications of Powell's study, there is no really sustained and well-developed critique of Heidegger either internal or external, sympathetic or unsympathetic, a failure not uncommon among Heideggerians. Moreover, there is no index of any kind--of topics, of names, or of texts of Heidegger--which impairs the book's usefulness. --J. D. C. (shrink)

Over the past decade, scores of articles have been published debating whether and when it is ethical for physicians to refuse requests from patients for legal, professionally permitted interventions. Numerous voices have condemned "conscientious refusals" for obstructing patients' access to needed and "standard" health-care services, for imposing physicians' personal ideologies on patients, and for contradicting physicians' professional ethical obligations. Conversely, other voices argue that conscientious refusals are essential for maintaining the integrity of clinicians as moral agents, for assuring the renown (...) of the broader medical profession, and for preventing the imposition of moral viewpoints onto minorities...

Local health departments and their employees are at the forefront of emergency preparedness and response. Yet, recent studies have found that some local public health workers are unwilling to report to work in a variety of disaster scenarios. This can greatly compromise a response, as many local health departments need “all hands on deck” to effectively meet increased demands. To address these concerns, local health departments have employed varied policy strategies to ensure that employees do report to work. After describing (...) different approaches taken by local health departments throughout the United States, we briefly identify and explore key ethics considerations that arise for local health departments when employees are required to report to work for emergency responses. We then discuss how these ethics considerations may inform local health department practices intended to promote a robust emergency response. (shrink)
