The Extended Atkinson Family and Changes in the Expenditure Distribution: Spain 1973/74-2003
No full textThis paper emphasizes the properties of a family of inequality measures which extends the Atkinson indices and is axiomatically characterized by a multiplicative decomposition property where the withingroup component is a generalized weighted mean with weights summing exactly to 1. This family contains canonical forms of all aggregative inequality measures, each bounded above by 1, has a useful and intuitive geometric interpretation and provides an alternative dominance criterion for ordering distributions in terms of inequality. Taking the Spanish Household Budget Surveys (HBS) for 1973/74, 1980/81, and 1990/91 and the more recent Continuous HBS for 2003, we show the advantages and possibilities of this extended family in regard to completing and detailing information in studies of inequality focussing on the tails of the distribution and on the changes in the distribution when the population is partitioned into population subgroups.inequality measurement, Atkinson indices
Evaluated kinetic and photochemical data for atmospheric chemistry: Volume III - gas phase reactions of inorganic halogens
No full textThis article, the third in the series, presents kinetic and photochemical data evaluated by the IUPAC Subcommittee on Gas Kinetic Data Evaluation for Atmospheric Chemistry. It covers the gas phase and photochemical reactions of inorganic halogen species, which were last published in J. Phys. Chem. Ref. Data, in 2000 (Atkinson et al., 2000), were updated on the IUPAC website in 2003 and are updated again in the present evaluation. The article consists of a summary sheet, containing the recommended kinetic parameters for the evaluated reactions, and five appendices containing the data sheets, which provide information upon which the recommendations were made

Corthylus microcorthyloides Atkinson 2020, new species
No full textCorthylus microcorthyloides Atkinson, new species Fig. 15 Diagnosis. This unusual species at first glance appears to be a species of Microcorthylus, especially because of its slender profile and the sulcate elytral declivity and small acute granules on interstriae 3. It differs from known species of that genus because the base of the pronotum has a fine raised lateral line. In most, possibly all species of Microcorthylus, the apices of the elytra are curved upwards and in direct posterior view the lower margin of the declivity is “v” shaped. In this species the apices are not upturned and the lower margin of the declivity forms a continuous curve. It could arguably be placed in that genus after revision of the character states that distinguish it from Corthylus. I have compared it to known species of Microcorthylus but it matches none of them. It would key to couplet 34 in Wood’s 1982 key to Corthylus, 53 in the 2007 key. In general appearance it most closely resembles C. convexifrons Wood. Female. Length: 1.6 mm, maximum width: 0.9 mm; length of elytra: 0.75 mm; length to width: 2.1; elytral length/ total length: 0.56; elytral length/width: 1.20. (n = 1). Color yellowish brown, slightly darker on declivity. Frons shining, flattened between eyes, weakly concave above epistoma to upper level of eyes; impunctate, without setae. A very faint longitudinal carina at upper level of eyes. Facets of compound eyes coarse, large in proportion to body size. Antennal club roughly oval, slightly asymmetrical. Short, erect, abundant setae distributed along entire perimeter of club, but not developed into a cirrus. Two straight sutures marked externally by shallow grooves, apparently not septate. Anterior margin of pronotum unarmed. Anterior slope with rows of flattened asperities to summit. Disc smooth, shining, impunctate. Elytra with discal striae and interstriae indistinct and confused at base, more distinct posteriorly with shallow punctures. Declivity abrupt in lateral profile, apex of elytra curved downwards. Interstriae 1 raised in a low costa; interstriae 2 impressed, impunctate. Interstriae 3 raised above level of 1 and 2, with 3 pointed denticles, each associated with a fine seta. Sparse, short setae also present on other posterolateral interstriae. Apical margin with a low, raised ridge, diverging from costal margin to about interstriae 7. Male. Unknown. Type material. Holotype: Mexico: Jalisco, Mascota, El Atajo, G.A. Quíroz R. and B.E. Díaz M., 2–31-X-2004, pitfall trap (NTP trap) (CNIN). Etymology. The specific name refers to the overall appearance which resembles a species of Microcorthylus.Published as part of Atkinson, Thomas H., 2020, New species, new records and synonymy of Mexican Corthylus Erichson, 1834 (Coleoptera: Curculionidae: Scolytinae), pp. 1-25 in Insecta Mundi 2020 (792) on page 22, DOI: 10.5281/zenodo.456489

Laguerre geometry of hypersurfaces in R-n
No full textLaguerre geometry of surfaces in R-3 is given in the book of Blaschke [Vorlesungen uber Differentialgeometrie, Springer, Berlin Heidelberg New York (1929)], and has been studied by Musso and Nicolodi [Trans. Am. Math. soc. 348, 4321-4337 (1996); Abh. Math. Sem. Univ. Hamburg 69, 123-138 (1999); Int. J. Math. 11(7), 911-924 (2000)], Palmer [Remarks on a variation problem in Laguerre geometry. Rendiconti di Mathematica, Serie VII, Roma, vol. 19, pp. 281-293 (1999)] and other authors. In this paper we study Laguerre differential geometry of hypersurfaces in R-n. For any umbilical free hypersurface x:M -> R-n with non-zero principal curvatures we define a Laguerre invariant metric g on M and a Laguerre invariant self-adjoint operator S:TM -> TM, and show that {g,S} is a complete Laguerre invariant system for hypersurfaces in R-n with >= 4. We calculate the Euler-Lagrange equation for the Laguerre volume functional of Laguerre metric by using Laguerre invariants. Using the Euclidean space R-n, the semi-Euclidean space R-1(n) and the degenerate space R-0(n) we define three Laguerre space forms URn, UR1n and UR0n and define the Laguerre embeddings URn1 -> URn and UR0n -> URn, analogously to what happens in the Moebius geometry where we have Moebius space forms S-n, H-n and R-n (spaces of constant curvature) and conformal embeddings H-n -> S-n and R-n -> S-n[cf. Liu et al. in Tohoku Math. J. 53, 553-569 (2001) and Wang in Manuscr. Math. 96, 517-534 (1998)]. Using these Laguerre embeddings we can unify the Laguerre geometry of hypersurfaces in R-n, R-1(n) and R-0(n). As an example we show that minimal surfaces in R-1(3) or R-0(3) are Laguerre minimal in R-3.MathematicsSCI(E)0ARTICLE173-9512
