Whence philosophy of biology?

A consensus exists among contemporary philosophers of biology about the history of their field. According to the received view, mainstream philosophy of science in the 1930s, 40s, and 50s focused on physics and general epistemology, neglecting analyses of the ‘special sciences’, including biology. The subdiscipline of philosophy of biology emerged (and could only have emerged) after the decline of logical positivism in the 1960s and 70s. In this paper, I present bibliometric data from four major philosophy of science journals (Erkenntnis, Philosophy of Science, Synthese, and the British Journal for the Philosophy of Science), covering 1930-1959, which challenge this view

Is greater decisionmaking power of women associated with reduced gender discrimination in South Asia?

"Recent research has shown that improving women's decisionmaking power relative to men's within households leads to improvements in a variety of well-being outcomes for children. In South Asia, where the influence of women's power is particularly strong, these outcomes include children's nutritional status and the quality of feeding and health care practices. Focusing on nutritional status, this paper presents the results of a study investigating whether increases in women's power have a stronger positive influence on the nutritional status of their daughters than their sons. If so, then increasing women's power not only improves the well-being of children as a group, but also serves as a force to reduce long-standing discrimination that undermines female capabilities in many important areas of life as well as human and economic development in general. To investigate this issue, the study draws on Demographic and Health Survey data collected during the 1990s in four countries: Bangladesh, India, Nepal, and Pakistan. The main empirical technique employed is multivariate regression analysis with statistical tests for significant differences in effects for girl and boy children. A total of 30,334 women and 33,316 children under three years old are included in the analysis. The study concludes that, for the South Asia region as a whole, an increase in women's decisionmaking power relative to men's, if substantial, would be an effective force for reducing discrimination against girl children. However, this finding is not applicable in all countries and for all areas and age groups of children. Indeed the study finds evidence that in some areas, for instance the northern and western states of India as a group, increasing women's power would lead to a worsening of gender discrimination against girls. This is likely the result of deeply embedded son preference associated with highly patriarchal social systems. The lesson for policymakers and development practitioners is that while increasing women's power is likely to improve the well-being of children, in some geographical areas it will not necessarily diminish discrimination against girls, which violates human rights and undermines the region's economic development and the health of its population. In these areas, to overcome son preference, economic returns to girls will have to be increased and efforts to change customs regarding marriage and inheritance associated with patriarchal kinship systems, which favor males, will have to be made."

A la recherche du “sens” perdu: Copyrightable Creativity Deconstructed

The primary goal of this article is to show how the concept of “creativity” as defined and applied by courts in copyright cases fails to map any reasonable concept of creativity in certain critical respects. Accordingly, the first charge undertaken here is a deconstructive one—to show the lack of meaningful overlap between the legal definition of creativity and the “actual” meanings of that same term. To undertake this comparison, Part II of this Article focuses on perhaps the more easily determined of these two definitions of the term—“creativity” as defined by courts. Rather than giving an unduly broad berth to this analysis, however, the Article will limit its review to creativity as applied in the context of Feist- based threshold creativity reviews. As a matter of further distillation, such cases will be highlighted where courts rely on an alternatives-based test to find creativity. This very commonly-applied test dictates that a creator’s work is creative under copyright if she enjoyed sufficient alternative means of communicating the idea underlying her work. Part III of the Article will show how the alternatives-based conception of creativity—while perhaps well-meaning and successful in promoting unrelated policy objectives—is ill-suited to measure the presence of actual creativity. This limited fit is demonstrated, in part, via a Proustian hypothetical that reveals inconsistent results between creativity according to courts and creativity in literary practice. Part III also attempts to prove such inconsistencies by drawing on scholarly legal literature on the topic of creativity. Having completed a deconstruction of the legal notion of “creativity,” part IV of this Article concludes on a more constructive, if not wholly restructuring, note by invoking a separate model of creativity that would seem to improve on the views of courts and computers—a model indirectly proposed by the Nobel laureate Bergson in his work The Creative Evolution, among others. Although the Bergsonian model may not be limited to rigid categorization, it focuses on creativity as a function of indeterminacy in the creative process and its embodied result. It is through just such a model that a more accurate, if more fluid, view of the term “creativity” may be conceived, in both general and copyrightable meanings of the word

The Frenchman

They spilled out over the German countryside in all directions. They stood bareheaded along the roads gaping pitifully at the invaders, still dumbfounded by their sudden release from the slave labor camp. A few hours before, their guards had fled inland to escape the long steel probing fingers of the allied armies. Like wild animals fleeing a forest fire, the prisoners that could still walk had poured forth (rum the hated camp as soon as their guards disappeared. They had no destination. At that moment they were nothing but starved animals putting all possible space between them and their infamous cages, looting and foraging along the way. It was like the lancing of a great carbuncle

Reactive self-heating model of aluminum spherical nanoparticles

Aluminum-oxygen reaction is important in many highly energetic, high pressure generating systems. Recent experiments with nanostructured thermites suggest that oxidation of aluminum nanoparticles occurs in a few microseconds. Such rapid reaction cannot be explained by a conventional diffusion-based mechanism. We present a rapid oxidation model of a spherical aluminum nanoparticle, using Cabrera-Mott moving boundary mechanism, and taking self-heating into account. In our model, electric potential solves the nonlinear Poisson equation. In contrast with the Coulomb potential, a "double-layer" type solution for the potential and self-heating leads to enhanced oxidation rates. At maximal reaction temperature of 2000 C, our model predicts overall oxidation time scale in microseconds range, in agreement with experimental evidence.Comment: submitte

Of evolution, information, vitalism and entropy: reflections of the history of science and epistemology in the works of Balzac, Zola, Queneau, and Houellebecq

This dissertation proposes the application of rarely-used epistemological and scientific lenses to the works of four authors spanning two centuries: Honoré de Balzac, Émile Zola, Raymond Queneau, and Michel Houellebecq. Each of these novelists engaged closely with questions of science and epistemology, yet each approached that engagement from a different scientific perspective and epistemological moment. In Balzac’s La Peau de chagrin, limits of determinism and experimental method tend to demonstrate that there remains an inscrutable yet guided excess in the interactions between the protagonist Raphaël and his enchanted skin. This speaks to an embodiment of the esprit préscientifique, a framework that minimizes the utility of scientific practice in favor of the unresolved mystery of vitalism. With Zola comes a move away from undefinable mystery to a construction of the novel consistent with Claude Bernard’s deterministic experimental medicine. Yet Zola’s Roman expérimental project is only partially executed, in that the Newtonian framework that underlies Bernard’s method yields to contrary evidence in Zola’s text of entropy, error, and loss of information consistent with the field of thermodynamics. In Queneau’s texts, Zola’s interest in current science not only remains, but is updated to reflect the massive upheaval in scientific thought that took place in the last half of the nineteenth and early part of the twentieth centuries. If Queneau’s texts explicitly mention advances like relativity, however, they often do so in a humorously dismissive manner that values pre-entropic and even early geometric constructs like perpetual motion machines and squared circles. Queneau’s apparent return to the pre-scientific ultimately yields to Houellebecq’s textual abyss. For Houellebecq, science is not only to be embraced in its entropic and relativistic constructs; it is these very constructs - and the style typically used to present them – that serve as a reminder of the abjection, decay, and hopelessness of human existence. Gone is the mystery of life in its totality. In its place remain humans acting as a series of particles mechanically obeying deterministic laws. The parenthesis that opened with Balzac’s positive coding of pre-scientific thought closes with Houellebecq’s negative coding of modern scientific theory

Common trends and common cycles in Canada: who knew so much has been going on?

It is generally accepted that convergence is well established for regional Canadian per capita outputs. The authors present evidence that long-run movements are driven by two stochastic common trends in this time series. This evidence casts doubt on the convergence hypothesis for Canada. Another prevalent belief is that Canada forms an optimal currency area (OCA). The authors uncover three serially correlated common cycles whose asymmetries suggest Canada is not an OCA. Their common trend-common cycle decomposition of regional outputs also reveals that trend shocks dominate fluctuations in Ontario, Quebec, and the Maritimes in the short run and long run but not in British Columbia and the Prairie region. Thus, regional Canadian economic fluctuations are driven by a rich, diverse, and economically important set of propagation and growth mechanisms.
