Cantaloupe melon ( Cucumis melo L.) conservation using hydrocooling

ABSTRACT Maintaining cantaloupe melon at field temperature impairs conservation as it speeds up cell metabolism and transpiration, and, consequently, reduces shelf life. This study aimed to evaluate the conservation of Torreon hybrid cantaloupe using the hydrocooling treatment. Fruits were harvested at the commercial maturity stage (60 days after planting), in the morning, at the Nova California Farm, municipality of Mossoró-RN, in September 2007. One set of fruit was immersed in chilled water at 5 ºC for 5 min, at the packing house, while the remaining set was not hydro cooled. Then, both sets (treated and untreated with hydrocooling) were pre-cooled in air forced tunnels at 7 ºC, until the temperature in the pulp reached 10 ºC. Both fruit sets were stored for 0, 14, 21, 28 and 35 days under modified atmosphere at 3 ± 1 oC and 90 ± 5% RH. After each storage period, the fruits were incubated in an atmosphere-controlled chamber at 20 ± 2 oC and 80 ± 5% de RH, for seven days. The following characteristics were evaluated: external and internal appearance, mass loss, soluble solids, firmness and titrable acidity. The experiment was arranged in a completely randomized split-plot design with four replications of three fruits. The plots consisted of the hydrocooling conditions (with and without fruit soaking in chilled water), and the sub-plots consisted of the storage times (0, 14, 21, 28 and 35 days).The treatment with hydrocooling was efficient in keeping the firmness and soluble solids of the fruits and shortened the pre-cooling time in the cooling tunnel. However, hydrocooling did not increase fruit shelf-life.

L'APPORT DE LA SOCIOLOGIE PRAGMATIQUE FRANÇAISE AUX ÉTUDES CRITIQUES EN MANAGEMENT

La sociologie pragmatique française (SP), inspirée des travaux de Luc Boltanski et Laurent Thévenot, est de plus en plus utilisée par les études organisationnelles en management. Pourtant, la dimension critique de cette approche n'a pas encore été intégrée au profit de la connaissance en management et organisations (MOK). Dans cet article, nous explicitons l'apport que cette sociologie peut représenter pour les études critiques en management (CMS). En tant que science de la science des acteurs, nous suggérons que la SP est fertile pour développer une approche de performativité critique. En particulier, nous démontrons que l'approche permet de mettre en lumière les nouvelles formes de domination plus complexes s'exerçant dans les organisations contemporaines. En utilisant des études empiriques d'organisations mobilisant la SP, nous montrons comment les concepts de compromis et d'épreuve développés par cette approche présentent un outillage permettant de renouveler la critique des organisations au profit de la MOK.

Migrations, Exils Et Reconfigurations Identitaires Dans Aaron D'yves Thériault Et L'espérance Macadam, De Gisèle Pineau

Utilisant à la fois la méthodologie des études littéraires et celle des études culturelles, le présent travail se propose de délimiter, dans les romans L'Espérance Macadam de l'Antillaise Gisèle Pineau et Aaron du Québécois Yves Thériault, la problématique de la migration et de l'exil ainsi que la conséquente rencontre des cultures à l'origine à la trans-culturalité, en mettant en évidence de nouvelles approches qui rompent avec les paradigmes ethnocentriques et en signalant de nouveaux pactes sociaux qui fondent une culture de la paix entre les hommes.

ESTRADAS LÍQUIDAS, COMÉRCIO SÓLIDO: ÍNDIOS E REGATÕES NA AMAZÔNIA (SÉCULO XIX)

O artigo analisa as relações entre os índios e os comerciantes ambulantes que, na Amazônia do século XIX, eram conhecidos como regatões. Com base em documentos da época, constata-se que nem sempre os índios foram vítimas ingênuas e passivas diante dos regatões e que é necessário enfatizar a dimensão simbólica das trocas, a fim de recuperar o protagonismo indígena nas relações estabelecidas com os comerciantes e com as mercadorias que eles vendiam.
