Abstract: coffee mother tree selection and progeny tests are being carried on at five localities in s. paulo. in order to test the most promising progenies simultaneously at these localities, five coffee regional selection trials were planted in 1951 at the experimental stations of the instituto agron?mico located at campinas, ribeir?o prêto, pindorama, mococa and jaú. data referring to the first six consecutive yielding years from the campinas trial are here discussed. this trial comprises 100 entries, corresponding to selected progenies of the cultivars 'mundo novo', 'bourbon amarelo', 'bourbon vermelho', 'caturra amarelo', 'caturra vermelho' and 'sumatra' and tester, unselected progenies of each one of these cultivars. four strains of typica variety were also taken as a general standard in order to measure the selection progress. besides the yield, expressed in kg of cherries and clean coffee, data were gathered referring to vegetative vigor, plant height, diameter of the plant at 50 cm from the soil, percentage of normal flat beans, peaberry and elephant seeds, seed weight and density, and also information about symptoms of zinc deficiency and frost damage. progenies of the cultivars 'mundo novo', 'bourbon amarelo' and 'bourbon vermelho' presented different yielding levels. the total (1954-1959) average yield of 'mundo novo' progenies was 9.81 kg of clean coffee per plot (plots of one single hole with four seedlings) while 'bourbon amarelo' progenies yielded 8.33 kg and 'bourbon vermelho' progenies, only 6.39 kg of clean coffee. 'caturra vermelho' gave 6.29 kg, while the 'caturra amarelo' progenies yielded 7.20 kg. comparisons between means indicated significant differences for the 'mundo novo' group of progenies. all 15 'mundo novo' selected progenies produced significantly more than the average standard of this cultivar. among the 'bourbon amarelo' progenies only 6 in 13 yielded more than the average standard and among the 51 'bonbon vermelho' progenies only 7 (13%) hav

Abstract: Se describe el dise o y los experimentos llevados a cabo con un simulador de un ecosistema sintético de tres componentes (autótrofos, consumidores primarios y consumidores secundarios) por autómatas celulares, de tipo IBM (individual-based model), donde cada agente exhibe su propia singularidad por responder a una serie de etiquetas fijas que se pueden denominar de modo algo laxo genes , en tanto que otras de tipo variable definen su estado interno. Este modelo, a modo de experimento pensado opaco , se destinó al estudio de la autoorganización, manifestada a través de la aparición y conservación de un orden espontáneo y al análisis de los factores que pudieran desestabilizar dicha estructura. Mientras que el simulador cuenta con un limitado número de interacciones codificadas de corto alcance, su desenvolvimiento exhibe efectos no codificados, de largo alcance, o emergentes, que suponen la presencia de procesos de autoorganización subyacentes.

Abstract: the coffee selection program of the instituto agronomico at campinas has been carried on in five experimental stations located in different ecological conditions. after identifying the best progenies in each station, a series of five trials was established to evaluate the adaptability of these selections to different localities. the present paper refers to a trial planted in the experimental station at mococa in the northeastern part of the stale of s. paulo, with heavy clay soil (massapê-salmour?o). the selected progenies of 'mundo n?vo' cultivar were superior to any other progenies studied in all characteristics considered: yield, vigor, and size and weight of flat seeds. among them the progenies cp 387-17, mp 386-2, cp 379-19 and mp 376-4 revealed to be the most promising ones for high yield, vigor and seed size. the progeny cp 387-17 produced 250 per cent more clean coffee than the tester 'tipica' commonly grown in the mococa region at the beginning of the coffee selection project. remarkable progress was observed in the selection of progenies by the pedigree method from the originai population of 'mundo n?vo'. the four best selections had an average production 100 percent higher than the original population. the results obtained confirm observations made for the same progenies grown in campinas and jau, in that the 'mundo n?vo' progenies have a very broad adaptation giving high yields in diverse ecological conditions.

Abstract: five coffee regional selection trials were established in 1951 in five localities representative of the main coffee producing regions of s?o paulo. these trials included selected strains of the cultivars 'mundo n?vo', 'bourbon amarelo', 'bourbon vermelho', 'caturra amarelo', 'caturra vermelho' and 'sumatra' and they will furnish information about the most adapted progenies for each locality. data obtained in the experiment station of the instituto agron?mico located at jaú, in the central plateau of the state, are discussed in the present paper. besides selected progenies this trial comprises a population without selection of each one of the cultivars and also of the tester 'típica' in order to have information about the effectiveness of the pedigree method for coffee breeding. the data point out the 'mundo n?vo' progenies are more vigorous and more productive than any other selection. their seeds are larger and heavier and the percentage of normal flat beans is also higher. the 'mundo n?vo' strains produce on the average 35, 84, 178 and 232 per cent more clean coffee than those of 'bourbon amarelo', 'bourbon vermelho', 'caturra' and 'típica', respectively. they rank also 77 per cent higher than the tester 'mundo novo' without selection. the best 'mundo n?vo' progenies in this trial are the same that had given the highest yields in the campinas trial indicating their broad adaptation to different ecological conditions. the 'mundo n?vo' progenies mp 376-4, cp 379-19, jp 381-3 and cp 387-17 are already being used for replanting the old coffee areas in the vicinity of jaú. these results confirm those previously obtained about the different yielding levels of the cultivars 'mundo n?vo', 'bourbon amarelo', 'bourbon vermelho' and 'caturra'.
Alternativas de análise de ensaios em látice no melhoramento vegetal
Pesquisa Agropecuária Brasileira , 2000,
Abstract: Compararam-se diferentes formas de análise de experimentos em blocos incompletos, abordadas como casos particulares de modelos mistos, quais sejam: (a) análise intrablocos, em que apenas o efeito do erro experimental é suposto aleatório; (b) análise interblocos (látice), com efeitos de blocos supostos aleatórios; (c) análise BLUP, com os efeitos de tratamentos supostos aleatórios, e (d) modelo aleatório. Além disso, montou-se a ANAVA, considerando duas alternativas: (e) usando o quadrado médio de tratamentos ajustados para blocos e o quadrado médio do erro efetivo do látice; (f) tomando as repeti es como blocos completos. Um exemplo de análise de um teste de progênies de Eucalyptus grandis (Hill) Maiden ilustra as implica es da escolha dos modelos para fins de sele o e de caracteriza o genética de popula es. Observou-se que em geral o ordenamento dos tratamentos sofreu maiores altera es ao se mudar a alternativa de análise do que as estimativas do progresso esperado pela sele o. Tendência que se refor a com a sele o mais intensa. As formas de análise que consideram a restri o da casualiza o (blocos incompletos) foram as mais precisas, e dentre estas, a análise BLUP de tratamentos é conceitualmente a melhor, pois os tratamentos eram progênies de poliniza o livre, sendo a que mais difere da análise usual do látice. Isto indica ser possível minorar os erros de sele o nas análises de blocos incompletos no melhoramento vegetal.

The 1964 Wellington Study of Beatlemania Revisited  [PDF]

Psychology (PSYCH) , 2014, DOI: 10.4236/psych.2014.515190
Abstract: In June 1964, an Honours class in clinical psychology set out to objectify the major parameters of crowd and audience reaction to the Beatles’ during the group’s three-day visit to Wellington, New Zealand. Advance publicity had warned of the “mass-hysteria” to be expected at the sight, sound and lyrics of the four lads from Liverpool. Adolescents anticipated their arrival eagerly, while the authorities were disparaging and somewhat fearful of the breakdown in law and order that might occur. The findings were published in Britain in 1966, taken a little further in the United States in1968, and the original published once more in Britain in 1992 by special request to encourage more psychologists to undertake research off campus. When writers from those countries mentioned the study recently near the 50th anniversary of the Beatles’ visit, it seemed interesting to review the accretion of similar studies that might have occurred. Sadly, the outcome showed that psychologists had not taken mass-audience research any further. Hence it was thought appropriate to lift the Wellington study from obscurity, in the hope of inspiring the next generation to make amends.
Estado novo: o fim das politicas regionais?  [PDF]
Abreu, Luciano Aronne de
Estudos Ibero Americanos , 2007,
Abstract: Em geral, a História Republicana do Brasil divide-se em antes e depois da Era Vargas, sendo este período o marco divisório entre o Brasil arcaico, marcado pelo clientelismo e pelo poder das tradicionais oligarquias políticas regionais, e o Brasil moderno, onde vigoram o universalismo de procedimentos e o ideal de manuten o da ordem e da unidade nacional. Ao longo deste texto, porém procuramos demonstrar que o Brasil é, na verdade, um pais sincrético, como define Edson Nunes, onde a arcaico e o moderno mantém-se em constante intera o, mesmo após as reformas de tipo universalista implementadas durante os anos Vargas. Durante este período, portanto, ainda que as políticas regionais tenham, de fato, sido limitadas em sua autonomia, novos canais de acesso e influência ao poder central permitiram às tradicionais oligarquais a manuten o de seu poder regional. Brazilian republican history is generally divided between before and after Vargas Era, landmark of the end of the “archaic Brazil”, ruled by traditional oligarchies regionally based, and the “modern Brazil”, characterized by the adoption of universal social proceedings and ideals of political order and national unity. Nevertheless, this paper aims to demonstrate that Brazil should rather be considered as a synchretic society, like defined by Edson Nunes. It means that archaism and modernity constantly interacted with each other, even though Vargas’ government intended to put into operation some reforms to establish the universality of political-administrative procedures. During this time, the autonomy of regional politics was in fact restricted, but new channels of influence in federal government allowed traditional oligarchies to keep power in their political supporting basis.
