The study of public administration has been characterized as a strong international focus, as both governments and scholars have sought to learn from the experience of other societies. While in a perfect world, one would expect a sort of pragmatic universalism, instead, many scholars tend to bring lessons from one country, or from a single cultural reality. This modest contribution lies in showing a series of national experiences rarely brought to the discourse about public administration in Brazil: Canada, Australia, India and the Philippines. Special emphasis will be given to the following: the origins and the development of public administration; the influence of ideology; and the complex tension between global theory and local practices.

A radioactive Western-blotting technique was developed by which the reactivity of Immunoglobulins (Igs) from different classes to both membrane radiolabelled and internal parasite antigens is simultaneously identified. The method includes radioiodination of parasites, polypeptide fractionation by SDS-PAGE, Western-blot transfer and autoradiography of the immunoblots developed with anti-Igs conjugates labelled with enzymes. The analysis is then performed by the comparison of common bands on the autoradiograms and the respective substrate stained nitrocellulose blots. This technique was used to analyse T. cruzi trypomastigote surface labelled antigens reactive to IgM, IgA and IgG specific antibodies. A different pattern of reactivity with acute Chagas' disease patients sera was thus obtained.

Fertilizer recommendations for cranberry crops are guided by plant and soil tests. However, critical tissue concentration ranges used for diagnostic purposes are inherently biased by nutrient interactions and physiological age. Compositional data analysis using isometric log ratios (ilr) of nutrients as well as time detrending can avoid numerical biases. The objective was to derive unbiased nutrient signature standards for cranberry in Quebec and compare those standards to literature data. Field trials were conducted during 3 consecutive years with varying P treatments at six commercial sites in Quebec. Leaf tissues were analyzed for N, P, K, Ca, Mg, B, Cu, Zn, Mn and Fe. The analytical results were transformed into ilr nutrient balances of parts and groups of parts. High-yield reference ilr values were computed for cranberry yielding greater than 35 Mg ha-1. Many cranberry fields appeared to be over-supplied with K and either under-supplied with Mn or over-supplied with Fe as shown by their imbalanced [K | Ca, Mg] and [Mn | Fe] ratios. Nutrient concentration ranges from Maine and Wisconsin, USA, were combined into ilr values to generate ranges of balances. It was found that these nutrient ranges were much too broad for application in Quebec or outside the Quebec ranges for the [Ca | Mg] and the [Mn | Fe] balances, that were lower compared to those of high yielding cranberry crops in Quebec.

OBJETIVO: Analisar, retrospectivamente, os resultados da radioterapia externa (RT) combinada a braquiterapia de alta taxa de dose (BATD), adjuvantes à cirurgia para o carcinoma de endométrio. MATERIAIS E MÉTODOS: Avaliamos 141 pacientes tratados com RT e BATD adjuvantes à cirurgia, no período de janeiro de 1993 a janeiro de 2001. RT pélvica foi realizada com dose mediana de 45 Gy, e BATD realizada na dose mediana de 24 Gy, em quatro inserções semanais de 6 Gy. A idade mediana das pacientes foi de 63 anos e a distribuição por estádio clínico (EC) foi: EC I (FIGO), 52,4%; EC II, 13,5%; EC III, 29,8%; EC IV, 4,3%. RESULTADOS: Com seguimento mediano de 53,7 meses, a sobrevida livre de doença (SLD) em cinco anos foi: EC I, 88,0%; EC II, 70,8%; EC III, 55,1%; EC IV, 50,0% (p = 0,0003). A sobrevida global em cinco anos foi: EC I, 79,6%; EC II, 74,0%; EC III, 53,6%; EC IV, 100,0% (p = 0,0062). Fatores que influíram na SLD foram grau histológico e histologia seropapilífera. Dos 33 casos que apresentaram recidiva da doença, em 13 (9,2%) esta ocorreu na pelve, vagina ou cúpula vaginal. RT + BATD do fundo vaginal permitiram o controle da doença em 90,8% dos casos. CONCLUSÃO: A RT exerce papel fundamental no controle loco-regional do câncer de endométrio e permite excelentes taxas de cura nos estádios iniciais. Para os estádios mais avançados, a falha terapêutica tende a ser a distância, sugerindo a necessidade de complementação terapêutica sistêmica, com introdução de novas modalidades de tratamento, em particular a quimioterapia.
