Utilização de abacaxi (Ananas comosus L.) cv. Pérola e Smooth cayenne para a produção de vinhos: estudo da composição química e aceitabilidade

Foram estudadas as características químicas de vinhos produzidos com as cultivares de abacaxi Pérola e Smooth cayenne, com vistas a predizer a qualidade das bebidas, tomando-se como base a sua composição e aceitabilidade. Os mostos de abacaxi foram analisados quanto ao pH, acidez total, ácidos orgânicos fixos, açúcar total, pectina total, compostos fenólicos, K, Ca, Fe, Cu, N e P, enquanto nos vinhos analisou-se também a acidez volátil, teor alcoólico, alcoóis superiores, acetaldeído, acetato de etila, glicerol, metanol e cor. Os resultados indicaram que existem semelhanças em relação à composição química de mostos e vinhos de abacaxis e uvas. A análise dos compostos voláteis formados durante a fermentação alcoólica indicou que a composição do mosto de abacaxi interferiu nas quantidades de alguns voláteis produzidos pela levedura Saccharomyces cerevisiae. O teste de aceitabilidade com escala hedônica de nove pontos indicou que os vinhos elaborados com as duas cultivares de abacaxi foram igualmente aceitos.

Boulevard to broken dreams, Part 1: the Polonoroeste road project in the Brazilian Amazon, and the World Bank's environmental and indigenous peoples' norms

ABSTRACT Before the mid 1980s the World Bank conceived "nature" as something to be "conquered" and "environment" as a source of resources for "development". By the late 1980s the Bank incorporated norms of environmental sustainability and indigenous peoples' protection into its mandate, and other development-oriented IOs followed. This two-part paper describes how a fight over the Polonoroeste road project in the Brazilian Amazon - inside the Bank, between the Bank and NGOs supported by the US Congress, and between the Bank and the government of Brazil -helped to generate the far-reaching change of policy norms. The first part describes how the project was designed as an innovation in sustainable development in rainforests; and how it provoked a firestorm inside the Bank as it moved towards project approval.

Rittermere Farm Craft Studio Fonds, 1951-2006

During the 1950’s, the Rittenhouse family of Vineland in the Niagara Peninsula opened a craft store and studio. Within a short period of time, they realized that resources for the craft of rug hooking were in demand and they began to build their business around this niche. Edna Rittenhouse, the mother, was the wool dyer; Margaret Rowan, the daughter, was the pattern designer; Ted Rowan, the son-in-law, changed careers and became the manager of the family business. The 1960’s were a prosperous time, not only in the Niagara Peninsula, but also for the Rittenhouse business. Edna Rittenhouse had been hooking rugs for decades but she and her family worked at developing and sharing newer techniques with newer materials. Shading manuals were authored and published; students became teachers; creativity abounded in the demand for and the creation of new designs. Instead of using woolen yarn, they were using pure woolen fabric; instead of using a standard cutter, they began using a uniquely designed cutter; instead of using frames, they employed a table top method. The new material and technique resulted in a rug with a smooth, uniform texture and a soft nap. Since many crafters belonged to crafters guilds, Margaret and Ted Rowan began promoting the idea of a guild for rug hookers and in time the Ontario Hooking Craft Guild was also a reality. A joint project between Chatelaine magazine and the Rittermere studio for Canada’s centennial year of 1967 was extremely well received within the circle of hooking crafters and the Rittermere Farm Craft Studio became a North American landmark for crafters. From this point onward the studio had a large customer base not only in North America but also overseas. The studio remained popular until 1984 when Margaret and Ted Rowan decided to retire. The Rittermere name has been preserved in the name of Rittermere-Hurst-Field which is a similar business located in Aurora which is just north of Toronto.

A Continuum of Traversing Lines: Youth Political Participation in Gaia Online

This qualitative research project uses a Deleuzo-Guattarian theoretical framework to address the question: “How are the politically oriented social forums in Gaia Online experienced as a continuum of overlapping of lines, including molar lines, lines of flight, and molecular lines?” Although smooth lines of flight may occur in Gaia, there are always mechanisms that work to re-territorialize them as more striated molar operations. Conversely, while more striated molar lines may be evident in Gaia, there are also smooth lines of flight that attempt to deterritorialize them as smooth space. Founded in 2003, Gaia is a virtual community in which members use 3D avatars to socialize with others, create content, and play games. Deleuze and Guattari (1987) have defined space with three systems: on one end is state-oriented static space, on the other end is nomadic fluid space, and situated in the middle is molecular space which contains both smooth and striating elements. While state-oriented striated space is based on routines, rules, and specifications, nomadic smooth space is flexible, always changing, and full of possibility. Some of the smoother operations that are evident in Gaia include becoming other, decentred communications, desire as resistance, and lines of flight. Some of the more striated operations include social reproduction of gender norms/expectations, capitalist mechanisms, violence and intolerance linked to categories and binaries (racism/sexism/ageism), the regulation of desire, and the organisation of bodies.

Investigating the Relationships Between Teacher Identity Norms and Collaboration

The purpose of this study was to investigate how teacher identity norms relate to teacher collaboration among the practices of elementary teachers in Ontario. Using quantitative research methods, the data indicated two clusters of teacher identity norms. The norm cluster of innovation, interdependence, and cooperation showed positive correlations with collaboration and the norm cluster of conservatism, individualism, and competition showed negative correlations with collaboration. The two clusters of norms also correlated with each other. The data showed that teachers highly valued collaboration as part of their teaching practice but did not always experience it in their school setting. The analysis suggested that if schools reinforce norms of innovation, interdependence, and cooperation, collaboration will be nurtured. Further, the data showed that if norms of conservatism, individualism, and competition are continued in school cultures, then collaboration will not be sustained. As a broad educational reform agenda, teacher collaboration is used (a) to support school cultures, (b) to change teaching practices, and (c) to implement policy-based initiatives. This research is expected to benefit teachers in its capacity to inform policy makers concerning the highly complex nature of teacher collaboration and some of the factors that impact it. With an understanding of the relationships between teacher identity norms and collaboration, it may be possible for policy makers to provide appropriate support structures that reinforce collaboration in teachers' practices as well as predict potential levels of collaboration within school cultures.

Probabilistic Assignments of Identical Indivisible Objects and Uniform Probabilistic Rules.

We consider a probabilistic approach to the problem of assigning k indivisible identical objects to a set of agents with single-peaked preferences. Using the ordinal extension of preferences, we characterize the class of uniform probabilistic rules by Pareto efficiency, strategy-proofness, and no-envy. We also show that in this characterization no-envy cannot be replaced by anonymity. When agents are strictly risk averse von-Neumann-Morgenstern utility maximizers, then we reduce the problem of assigning k identical objects to a problem of allocating the amount k of an infinitely divisible commodity.
