Dalbergia miscolobium or Jacarandá do Cerrado is a species of legume in the Fabaceae family. It occurs in the sensu stricto Cerrado and in the dystrophic cerradão. It shows potential for landscaping and for recovering damaged areas. It is an endangered species and therefore is protected by the law that prevents cut in areas of the Federal District (Decree No. 14.783/93). The purpose of this study was to determine the best procedure to prepare seeds of Dalbergia miscolobium to assess viability in the tetrazolium test. We carried out the following treatments: i) hydration on filter paper at 25 ° C, ii) hydration on filter paper at 25 ° C followed by a cut in the tegument and iii) hydration on filter paper at 25 ° C followed bya complete removal of the tegument. The results were analyzed using analysis of variance and the Tukey range test. The analyzes showed that the best procedure to prepare seeds of Dalbergia miscolobium is the treatment in which there is a hydration followed by the complete removal of the integument. Where 78% of the seeds showed uniform staining, indicating that the seeds analyzed are of good quality. The other treatments, hydration and hydration followed by cutting, showed respectively 35% and 41% of viable seeds. RESUMO A Dalbergia miscolobium ou Jacarandá do Cerrado é uma espécie de leguminosa da família Fabaceae. Ocorre no sentido stricto Cerrado e no cerradão distrófico. Possui potencial para paisagismo e para recuperar áreas degradadas. É uma espécie ameaçada de extinção e, portanto, está protegida pela lei que previne o corte em áreas do Distrito Federal (Decreto 14.783 / 93). O objetivo deste estudo foi determinar o melhor procedimento de prepararação das sementes de Dalbergia miscolobium para serem submetidas à análise de viabilidade pelo teste de tetrazólio. Foram realizados os seguintes tratamentos: i) hidratação em papel de filtro a 25 ° C, ii) hidratação em papel de filtro a 25 ° C seguida de um corte no tegumento e iii) hidratação em papel de filtro a 25 ° C seguido de remoção completa do tegumento. Os resultados foram analisados utilizando-se a análise de variância e o teste de médias de Tukey. As análises mostraram que o melhor procedimento para preparar sementes de Dalbergia miscolobium é o tratamento em que há uma hidratação seguida pela remoção completa do tegumento, onde 78% das sementes apresentaram coloração uniforme, indicando que as sementes analisadas são de boa qualidade. Os demais tratamentos, hidratação e hidratação seguida de corte, mostraram respectivamente 35% e 41% de sementes viáveis.

En el presente artículo se estudia el imaginario urbano de la Ciudad de México valiéndose de la comparación de la perspectiva de una muestra de residentes del Distrito Federal con otra muestra de funcionarios encargados de la gestión de la metrópoli. Se parte del supuesto de que las imágenes que esta gran ciudad suscita corresponden a dos registros distintos: por un lado la experiencia urbana captada a través del discurso sobre la ciudad y por el otro las imágenes cartográficas que se materializan en mapas cognitivos del espacio. Se presentan aquí los resultados de estas dos perspectivas complementarias de análisis de las representaciones de la ciudad y se propone una metodología para su estudio. Asimismo se analiza si la vivencia y la representación de la ciudad corresponden a las propuestas teóricas que plantean que la metrópoli contemporánea ya no es más un lugar de convivencia, sociabilidad e identidad, sino que se ha convertido en un espacio únicamente funcional. AbstractThis article studies the urban imagination in Mexico City, using the comparison of the perspective of a sample of residents from the Federal District with another sample of functionaries in charge of managing the metropolis. It begins with the assumption that the images this great city evokes correspond to two different registers: on the one hand, the urban experience recorded through the discourse on the city and on the other, the cartographic images materialized in cognitive maps of space. This article presents the results of these two complementary methods of analyzing the representations of the city and proposes a methodology for studying them. It also analyzes whether the experience and the representation of the city correspond to the theoretical proposals suggesting that the contemporary metropolis is no longer a place of coexistence, sociability and identity but has become a purely functional space.

Trata-se de um estudo sobre políticas públicas para educação onde foram priorizadas as questões da melhoria de qualidade de ensino e da continuidade e descontinuidade na implementação dos programas. Através de pesquisa centrada nos planos quadrienais e propostas curriculares, verificou-se que o sistema público de ensino do Distrito Federal, no período de 1979/1988, foi objeto de duas gestões, cujas propostas, apesar do traço comum da busca de melhoria qualitativa, apresentavam-se diametralmente opostas. As diferenças de posturas teóricas e os procedimentos adotados pelas duas administrações — uma, marcada pelo centralismo, verticalismo e tecnicismo; outra, pelo esforço de democratização do espaço escolar — não asseguraram, todavia, o pretendido avanço qualitativo. Abstract This is a study on public education politicswhich privileged better quality schooling issues as well as continuity and discontinuity in the programmes implantation. This research shows that public education in the Federal District has gone through two different managements whose politics — although both were trying to enhance schooling quality — stand on diametrical opposi tes. The differences in theoretical postures and procedures adopted by both administrations — one characterized by centralism, verticality and technicality, the other by its school democratization effort — were not, however, successful in realizing the expected quality betterment. Résumé Ils 'agit ici d'une étude des différentes politiques pour l 'éducation publique qui ont privilégié les questions d'amélioration de la qualité de l'enseignement ainsi que celles de la continuité et des ruptures lors de l'implantation des programmes. La présente recherche a constaté que le système d'instruction publique du District Fédéral a connu deux gestions dont les politiques, bien qu 'ayant l'objectif commun d'amélioration de la qualité, se sont montrées diamétralement opposées — les différences de postures théoriques et manières de procéder adoptées par chacune des deux administrations. Resumen Este es un estudio sobre políticas públicas para la educación en el cual se ha dado prioridad a las cuestiones de mejora en la calidad de ensenanza, y continuidad/discontinuidad en la implementación de programas. La investigación demostró que el sistema público de ensenanza en el Distrito Federal ha sido objeto de dos gestiones que, malgrado proponiendo las dos la mejora en la calidad, sus políticas resultaron diametralmente opuestas entre si. Las posturas teóricas y los procedimientos prácticos se presentan muy distintos. Una adminstración se ha caracterizado por el centralismo, el verticalismo y el tecnicismo; mientras la otra, por el esfuerzo en la democratización del espacio escolar. Sin embargo, ni ¡a una, ni la otra, han logrado el prometido adelanto en la calidad de la ensenanza.

The late Miocene Chinese hipparions are morphologically diversified showing similarity to both western Old World's and North American forms. Two Chinese taxa that are phylogenetically related to western Old World's forms are Hipparion fossatum (= H. forstende) from Baode (Shanxi) and H. hippidiodus from Qingyang (Gansu) and Baode. The former is related to H. mediterraneum and the latter to H. urmiense - platygenys from the Turolian localities in the western Old World. H. fossatum and H. hippidiodus are associated with the “dorcadoides” (open-land) and “mixed” faunas in northern China. Hipparion fossatum that is characterized by POF located close to the orbit co-occurs with large and morphologically specialized form, H. dermatorhinum in Baode (Loc.30). H. hippidiodus with reduced POF is discovered with smaller H. coelophyes in Loc. 43, 44 (Baode) and Loc. 115 (Gansu).The hipparions associated with the “gaudryi” (forest) fauna are characterized by well defined and small POF located far from the orbit. Those forms are: H. platyodus from Loc. 70; H. ptychodus from Loc. 73; H. tylodus from Hsi-Liang in Yushe - Wuxiang basins; and H. sefvei from Loc. 12 at Xin-an in Henan province. H. coelophyes from Baode (Loc.43 & 44) and Qingyang (Loc. 115) also show similar facial morphology to the these forms, although it has small size and shallow POF. Those forms are similar in facial and dental morphology to Hipparion sensu stricto and some species of Cormohipparion in North America.The assemblages of Chinese hipparions are composed of two groups whose members are phylogenetically similar to the forms from both western part of Eurasia and North America. The “gaudryi” fauna is considered younger than the other two on the basis of faunal analyses. The similarity in hipparionine taxonomy between northern China and North America in the latest Miocene is an evidences for possible faunal interchange(s) occurred during that period, as suggested by taxonomic analyses on carnivores and proboscideans in eastern half of Eurasia and North America.

AbstractThe systematics of Acalymma sensu stricto of North America including Mexico are revised. Acalymma sensu stricto is defined and distinguished from the other species groups of Acalymma. Sixteen species are discussed including four new species: A. blomorum, A. palomarense, A. invenustum, and A. luridifrons all from Mexico. Three new subspecies of A. blandulum (LeConte) are described: blandulum (LeConte) new status, nigriventre, and yucatanense. Acalymma coruscum costaricense Bechyné is placed as a synonym of A. innubum (Fabricius). Keys are presented to all species and subspecies. Habitus and male genitalia drawings are given for all species and distribution maps are given where appropriate.

Range Test

If used only when a preliminary F test yields significance, the usual multiple range procedures can be modified to increase the probability of detecting differences without changing the control of Type I error. The modification consists of a reduction in the critical value when comparing the largest and smallest means. Equivalence of modified and unmodified procedures in error control is demonstrated. The modified procedure is also compared with the alternative of using the unmodified range test without a preliminary F test, and it is shown that each has advantages over the other under some circumstances.

1. The colour of the minnow Phoxinus phoxinus L. and its ability to undergo colour change were studied after partial and complete blinding. The blinding was accomplished either by section of the optic nerve or by tectal ablation. 2. Following bilateral section of the optic nerve the blinded minnows darken. After the initial darkening, half of the fish pale and the other half remain dark. 3. The colour of the fish blinded by bilateral section of the optic nerve could not be affected by external conditions. 4. Following complete removal of the optic tectum the fish at first paled, but after 24 h they darkened to very variable tints. 5. Unilateral section of the optic nerve coupled with unilateral tectal removal on the same or opposite side did not affect the ability of the fish to change colour. 6. The bilateral removal of the anterior tectum from a blinded darkened fish did not affect its colour. 7. The bilateral removal of the posterior tectum of a darkened fish caused maximal pallor. 8. By a series of lesions an area in the dorsal posterior part of the optic tectum was found to cause darkening in the blinded fish because following its removal the fish paled. 9. It is suggested that the fibres from the tectum may act by exciting or inhibiting the neurones of the paling centre in the anterior medulla.

The chirostyloidean squat lobster genus Gastroptychus Caullery, 1896 is revised and is split into two genera: Gastroptychus sensu stricto (type species, Ptychogaster spinifer A. Milne-Edwards, 1880) and Sternostylus new genus (type species, Ptychogaster formosus Filhol, 1884). Gastroptychus sensu stricto, is restricted to nine species with a sternal plastron, at sternite 3, abruptly demarcated from the preceding sternites (excavated sternum) by a distinct step forming a well-defined transverse or concave anterior margin at the articulation with maxillipeds 3, the maxillipeds 3 widely separated, with the distal parts accommodated in the excavated sternum between the left and right maxillipeds 3 when folded, and the P2–4 dactyli with the terminal spine demarcated by a suture. Sternostylus new genus, represented by 12 species, has the sternite 3 anteriorly bluntly produced medially and steeply sloping anterodorsally to the anterior sternite, with a pair of spines directly behind the anterior margin, the left and right maxillipeds 3 adjacent, and the P2–4 dactyli ending in an indistinctly demarcated corneous spine. The above-mentioned characters of Gastroptychus are consistent with Chirostylidae sensu stricto. Published molecular phylogenies indicate, however, that Sternostylus is the sister group to all the other Chirostylidae, and is designated the type genus of a new family, Sternostylidae.
