Sensometrics: a análise sensorial de bebidas numa perspetiva estatística
Conferência plenária apresentada em 20 de Maio de 2016 no Fórum ALABE 2016A utilização de pessoas como instrumentos de medida, desde «simples» consumidores a participar em estu-dos de mercado até provadores treinados ou peritos integrando painéis de provadores, é cada vez mais importante no desenvolvimento e controlo de qualidade de produtos alimentares e de bebidas.
O vinho é uma bebida fascinante e complexa, na qual uma grande multiplicidade de aromas e sabores po-dem ser identificados e dependem de vários fatores, das castas ao terroir ou ao processo de vinificação. A avaliação da sua qualidade é essencial e, tradicionalmente, realizada pelos enólogos, mas outros intervenien-tes na indústria têm a responsabilidade de avaliar a qualidade do vinho. Essa avaliação é, muitas vezes, reali-zada recorrendo à análise sensorial (viz. "ciência envolvida na avaliação das características organoléticas de um produto pelos sentidos"). Para além das condições ambientais e do “protocolo laboratorial”, os testes sensoriais são, em termos de planeamento e análise (estatística) de resultados, como testes de hipóteses estatísticas/significância estatística cujo modus operandi está relacionado com o método cientifico.
Neste contributo, proponho a tradução e definição do conceito de Sensometria, apresento de forma ele-mentar e sumária algumas das técnicas e métodos estatísticos mais relevantes e/ou emergentes em análise sensorial, com referência ao software utilizável e que facilita a tarefa (com enfoque na linguagem de pro-gramação e sistema de computação R), assim como exponho os aspetos importantes a considerar no plane-amento e análise de resultados de provas/testes sensoriais que contribuem para a validade e generalidade das conclusões

Seasonal variations in gross biochemical composition, percent edibility, and condition index of the clam Ruditapes Decussatus cultivated in the Ria Formosa (South Portugal)
The grooved carpet shell clam, Ruditapes decussatus (L. 1758), is one of the most popular and profitable molluscs exploited in rearing plots in the Mediterranean. However, annual catch has been declining steadily since the early nineties. In order to understand the seasonality of its nutritional value, thus providing an improved basis for economical valuation of the resource, gross biochemical composition, percentage edibility and condition index were investigated during a year with monthly periodicity in a commercially exploited population of the clam Ruditapes decussatus in the Ria Formosa, a temperate mesotidal coastal lagoon located in the south of Portugal. Our results show that total and non-protein nitrogen co-varied during the year, resulting in a protein content that peaked in the warmest months. Although complementary in summer, carbohydrate and lipid contents showed irregular annual trends. The observed seasonality was comparable to that shown by studies elsewhere at similar latitudes, and are underpinned by the reproductive cycle of the species. Our results show the clams to be at their prime nutritional value at the beginning of summer, when protein content peaks
Composing music with case-based reasoning
Comunicação apresentada na International Conference on Computational Models of Creative Cognition, Dublin, 1997.Music is one of the most intriguing and joyful
domain of research and analysis. Driven by this
insatiable curiosity, Musical Analysis has
emerged to formally understand and structure
music and its intrinsic intention and causality.
Each complete analysis of a piece points to
issues that go far beyond the normal graphical
music representation. A better analysis is
important not only to a better interpretation, but
also to a more perfect composition. An
exceptional composer is indeed an exceptional
analyst.
This paper presents a computational approach to
music composition through the use and
exploration of musical analysis. Centered on
Case-Based Reasoning and Planning techniques,
it consists on creating new solutions by keeping,
transforming and extrapolating knowledge from
already expert-made music analysis. For our
approach, each analysis is represented as a
precisely structured Case, divisible into all of its
components.
The process of composition we adopt is
progressive, left-to-right, and top-to-bottom and
has some similarities with (Wallas’ 1926) theory
for creative production (Macedo et al. 1996a)
which we adapted for this specifically structured
and complex domain.
The resulting implemented program has already
generated several different musical pieces, which
were examined and analyzed by experts, bringing
up precious questions and advice
Lna santé - the home care pioneer in France
Begun operating in 1992 and today is ready to be bought and to grow massively in the upcoming years .LNA Santé, the fifth French player in the long-term care market ,will be acquired in 2019 in a Private Equity deal and will improve its operations in Europe. This deal is expected to return 3.1 x the money invested by the fund and an internal rate of return of almost 26% with an exit in five years(2023). This successful exit is possible due to an ageing population that is set to in crease demand for dependent care which is reflected in the number of nursing home beds forecasted to double. By the time of exit, the firm will amount €828 Mofre venues and €94 Mof EBITD As treaming from consolidation of operations in the current operating countries–France and Belgium–and an internationalization bet in the Netherlands. It is presumed that this paper will inform how a deal in Private Equity -term care market in Europe is conducted
