A New Species of \u3ci\u3eEuryurus\u3c/i\u3e From Southern Alabama and Remarks on the Status of \u3ci\u3eIlliniurus Beattyi\u3c/i\u3e Shear (Diplopoda: Polydesmida: Euryuridae).

A new species of polydesmidan millipede of the family Euryuridae, Euryurus lecythanoictes, is described. Another millipede of Euryuridae, Illiniurus beattyi Shear, is considered to be an aberrant specimen and therefore not a true species. The family taxonomic history of Euryuridae is briefly covered with a discussion of gonopod anatomy

Mandated Disclosure, Stock Returns, and the 1964 Securities Acts Amendments

The 1964 Securities Acts Amendments extended the mandatory disclosure requirements that had applied to listed firms since 1934 to large firms traded Over-the-Counter (OTC). We find several pieces of evidence indicating that investors valued these disclosure requirements, two of which are particularly striking. First, a firm-level event study reveals that OTC firms most impacted by the 1964 Amendments had abnormal excess returns of about 3.5 percent in the weeks immediately surrounding the announcement that they had begun to comply with the new requirements. Second, we estimate that the most affected OTC firms had abnormal excess returns ranging between 11.5 and 22.1 percent in the period between when the legislation was initially proposed and when it went it went into force, relative to unaffected listed firms and after adjustment for the standard four-factor model. While we cannot determine how much of shareholders' gains were a transfer from insiders of these same companies, our results suggest that mandatory disclosure causes managers to more narrowly focus on the maximization of shareholder value.

Caenorhabditis elegans rab-3 mutant synapses exhibit impaired function and are partially depleted of vesicles

Journal ArticleRab molecules regulate vesicular trafficking in many different exocytic and endocytic transport pathways in eukaryotic cells. In neurons, rab3 has been proposed to play a crucial role in regulating synaptic vesicle release. To elucidate the role of rab3 in synaptic transmission, we isolated and characterized Caenorhabditis elegans rab-3 mutants. Similar to the mouse rab3A mutants, these mutants survived and exhibited only mild behavioral abnormalities. In contrast to the mouse mutants, synaptic transmission was perturbed in these animals
