Implementação da técnica de extração de dispersão da matriz em fase sólida ("MSPD") para determinação de resíduos de agrotóxicos em laranjas

Um método de extração de multiresíduos baseado na técnica de dispersão da matriz em fase sólida ("MSPD"), foi otimizado e validado para a extração e análise cromatográfica de 27 agrotóxicos (isômeros a, b, g, d do hexaclorociclohexano (HCH), dieldrin, endrin, heptacloro e seu epóxido (HE), a e b-endosulfan, o,p'-DDD, p,p'-DDD, o,p'-DDE, p,p'-DDE, o,p'-DDT, p,p'-DDT, dicofol, metoxicloro, mirex, hexaclorobenzeno (HCB), clorotalonil, parationa metílica, fenitrotiona, malationa, folpete, diazinona, cis e trans-permetrina em laranjas. A amostra macerada é inicialmente homogeneizada com C18, o homogeneizado é transferido para uma coluna de vidro contendo sílica gel onde se adiciona 10mL de acetato de etila como solvente de eluição. O eluente é concentrado, diluído em isooctano e 1mL deste é injetado no cromatógrafo a gás. Para a separação e quantificação dos 27 agrotóxicos, foi utilizado um CG/DCE. A confirmação dos mesmos foi feita por espectrometria de massas. Para a quantificação dos 27 agrotóxicos utilizou-se a padronização externa. As recuperações dos mesmos variaram de 70 a 120%, considerando-se os níveis de adição agrotóxicos/amostra de 0,02 e 2,0mg/kg. Os limites de quantificação variaram de 0,01 a 0,5mg/kg.

Efeito da idade da matriz sobre o rendimento e qualidade da carne de frangos de corte

O experimento foi conduzido na Faculdade de Medicina Veterinária e Zootecnia da UNESP, Campus de Botucatu, para avaliar o efeito da idade da matriz no desenvolvimento, rendimento e qualidade da carne de frangos de corte. Ovos de matrizes da linhagen Ross x Ross provenientes de lotes com 29, 41, 58, 68 e 98 semanas de idade foram selecionados e incubados em idênticas condições. Após a eclosão, três mil e seiscentos pintinhos de um dia foram alojados, ao acaso, em um esquema fatorial 5 x 2, ou seja, 5 idades e 2 sexos, e criados até 49 dias de idade. Com 21, 28, 35, 42 e 49 dias de idade, 25 aves de cada tratamento foram selecionadas e abatidas após um período de 8 horas de jejum alimentar. De acordo com resultados obtidos, a idade da matriz afetou (P<0,05) a espessura do filé do peito e o rendimento de carne de peito aos 49 dias de idade, com melhores resultados para frangos originados de matrizes com 29 semanas de idade. O pH do peito e da perna sofreu uma variação bastante acentuada, sendo menor nas aves oriundas de matrizes mais velhas e maior nas aves oriundas de matrizes mais novas. Já a perda de peso por cozimento e a força de cizalhamento não foram afetados pela idade da matriz.

THE ROLE OF CULTURAL AWARENESS IN BUILDING CHINESE HEALTH FOOD BRANDS Using Netnography in Searching Cultural Arguments to Be Used for Marketing Health Foods in China

Despite the complexity of the Chinese culture consumer product businesses should apply them in building brands for Chinese markets. There are reasons to believe that cultural values and attitudes affect the buying behavior of Chinese consumers. Companies that wish to create brands in China should therefore be aware of the prevailing cultural values and consumer attitudes. This thesis will examine which values and attitudes mostly affect Chinese consumers of health food products. The study will be done by conducting a netnography. Because netnography is actually a collection methods rather than a single method, other auxiliary methods will also be applied. These methods are emotion, language and sentiment analysis (ELS analysis). Emotion analysis will be conducted because cultural values are mostly built on emotional basis. Sentiment analysis will assist in recognizing the key factors that help to locate values and attitudes. Because the netnography will be conducted in Chinese web forums by a non-native researcher, linguistic aspects should also be analyzed in parallel with emotions and sentiment analysis. The study shows that the Chinese consumers of health food products put much importance on functional, analytical and collectivistic attitudes as well as social and psychological values. Of all the twelve cultural values defined, the role of family rose above all. Also perseverance, frugality, guanxi and harmony were highly presented. The attitudes were found by recognizing certain attitude factors. Of all the factors, health foods’ functional benefits and aesthetic content together with consumers’ value consciousness surpassed other factors. Besides these results that can be applied by foreign health food companies willing to enter Chinese consumer markets, also academia can benefit this new approach for conducting ethnographies online.

Representations of cultural encounters in the global business press – The importance of cross-cultural competence

This qualitative study has started from the interest to examine how the reality of crosscultural encounters is presented in the global business press. The research paper emphasizes different ways to classify culture and cross-cultural competency, both from the point of view of individuals and organizations. The analysis consists of public discourses, where cross-cultural realities are created through different persons, stories and contexts For data collection, a comprehensive database search was performed and 10 articles from the widely known worldwide business magazine The Financial Times were chosen as the data for the study paper. For the functions of addressing the research study questions, Thematic Content Analysis (TCA) and also Discourse Analysis (DA) are utilized, added with the continuous comparison method of grounded theory in the formation of the data.The academic references consist of literary works and articles presenting relevant concepts, creating a cross-cultural framework, and it is designed to assist the reader in the navigation through the topics of culture and cross-cultural competency. The repertoires were formed from the data and following, the first repertoire is contrast difference between home and target culture that the individual was able to discern. As a consequence of the first repertoire, the companies then offer cultural training to their employees to prepare them to situations of increasing levels of cultural variation. The third repertoire is increased awareness of other cultures, which is conveyed as a result of cultural training and contextual work experience. The fourth repertoire is globalization as an international business environment, where the people in the articles perform their job functions. It is stated in the conclusions that the representations emphasize Western values and personal traits in leadership.
