Eisenberg, J. F., and Edwin Gould. The Tenrecs: A Study in Mammalian Behavior and Evolution. Smithsonian Contributions to Zoology, 27: 1-137. 1970.—Tenrecs are found only on the island of Madagascar. The biology of the Tenrecidae is described by field and laboratory studies that focused on comparisons of social behavior and communication in several species. Detailed observations on the behavior...

This paper discusses necessary and sufficient conditions on a monoid S, such that a class D of left S-acts is first order axiomatisable. Such questions have previousely been considered by Bulman-Fleming, Gould, Stepanova and others. Let C be a class of embeddings of right S-acts. A left S-act B is C-flat if tensoring with any B ∈ D preserves the embeddings in C. We find one or two (depending on...

This article analyzes the impact of the resurgence of American creationism in the early 1980s on debates within post-synthesis evolutionary biology. During this period, many evolutionists criticized Harvard biologist Stephen Jay Gould for publicizing his revisions to traditional Darwinian theory and opening evolution to criticism by creationists. Gould's theory of punctuated equilibrium was a s...

The firefly luciferase protein contains a peroxisomal targeting signal at its extreme COOH terminus (Gould et al., 1987). Site-directed mutagenesis of the luciferase gene reveals that this peroxisomal targeting signal consists of the COOH-terminal three amino acids of the protein, serine-lysine-leucine. When this tripeptide is appended to the COOH terminus of a cytosolic protein (chloramphenico...

Let me say at once, the tentative and rather speculative ideas I am presenting here are not intended to answer the question of what time is, in an ontological sense. I am interested in how the thinking mind might come to have a concept of time. This concept has been a problem from the beginning of Western philosophy. It was implicit in the irreconcilable conflict between Parmenides' notion of a...

In recent years, large numbers of lithium-rich stars were discovered near several nearby star forming regions (SFRs). We present a detailed study of those stars discovered in and near the central region of the Taurus-Auriga T Tauri association, based on high-resolution echelle spectroscopy and proper motion data. We find that about 60 per cent of our sample can be regarded as pre-main sequence ...

In their paper, “Punctuated Equilibria: An Alternative to Phyletic Gradualism”, Eldredge and Gould (1972) argue that most evolution occurs during geologically rapid speciation events, with species exhibiting stasis the vast majority of the time. Gould (2002, 2007) demonstrates that an implication of Punctuated Equilibrium is that selectionist theory is expanded to the level of species defining ...

This paper concerns with a generalization of Sz?sz-Baskakov operators, which includes Boas-Buck-type polynomials. The convergence properties are studied in weighted space and the rate is obtained by using modulus continuity. A Voronovskaya-type theorem investigated. Also, theoretical results demonstrated choosing particular cases polynomials, namely Appell Hermite Gould-Hopper Laguerre polynomi...
