Sustainability is a topic that is increasingly discussed in society and organizations, leading many companies to adopt communication strategies focused on this theme. The objective of this article was to identify in the literature the ways, means, or tools that companies use to communicate sustainability. This article was based on a systematic review of the literature on the topic, resulting in a final sample of 18 articles from 14 different journals. Seven potential topics were identified in the systematic review: (i) communication strategies, (ii) the relationship between communication and Citation: Borges, E.; Campos, S.; Teixeira, M.S.; Lucas, M.R.; Ferreira-Oliveira, A.T.; Rodrigues, A.S.; Vaz-Velho, M.

The results obtained allowed us to conclude that the strategies that companies can use to communicate sustainability are as follows: use new technologies (internet, social networks, websites, etc.), make value propositions based on consumer behaviors, disseminate clear and consistent information, and ensure broader work teams, among others. These results contribute to the advancement of scientific literature and to the definition and implementation of more efficient and effective public policies that facilitate communication between companies and consumers. Finally, this paper offers practical suggestions to formulate sustainable communication strategies.

Purpose | The eco-labelling of food products is an integral part of the transition to a sustainable food system, as it allows consumers to make informed, healthier and more sustainable choices. It reinforces the reputation of companies, showing that they are socially responsible and concerned about environmental issues. The aim of this study is to identify the determinants of the purchase of eco-labelled food products in the Portuguese context. Methodology/Approach | An online questionnaire was carried out among the Portuguese population over 18 years old. Data analysis techniques including descriptive analyses, parametric and non-parametric tests, linear correlation and regression analysis were applied. Expected Results | We expect to identify a positive correlation between consumers' attention to companies' Green Marketing communication and green purchasing behaviour, as well to obtain a positive correlation between the Communicated Socio-environmental Use (CSU) of the producer's declared commitment and green purchasing behaviour. These results are valuable for companies’ managers to develop and evaluate specific communication and marketing actions to the markets, taking into account current consumer preferences.

Resumo A questão das cotas raciais gera grande polêmica na sociedade brasileira fortemente marcada pela crença na ideologia da “democracia racial”. Assim sendo, conquista uma grande rejeição em vários setores da sociedade, inclusive entre a população negra e carente para as quais a medida foi desenvolvida. O objetivo deste artigo é desenvolver uma análise sobre a percepção de estudantes pretos e pardos sobre a política de cotas e os discursos que visam deslegitimar aos olhos desse grupo o ingresso no ensino superior mediante cotas raciais. Palavras-chave: Cotas raciais; Ensino superior; Percepções. Abstract The question of racial quotas generates great controversy in Brazilian society strongly marked by belief in the "racial democracy" ideology. Therefore it earns a great rejection in several sectors of society, including among the black and poor for which the measure was developed . The purpose of this article is to develop a analysis on the perception of black and brown students about the quota policy and speeches aimed  to delegitimizing at the eyes of this group the entry into higher education by racial quotas. key-words:  Racial quotas; High Education; Perceptions.

The best of our knowledge no study in the literature has compared the bilateral electromyographic activation of the multifidus and longissimus dorsi muscles between the squat and hip thrust exercise. The aim of the present study was to compare the electromyographic activation by bilateral measurement of the multifidus and longissimus dorsi muscles between the squat and hip thrust exercise in 9 university bodybuilding competitors who were using both exercises in their training routine. The results show that both muscles increased electromyography activity in the ascending phase. Regarding the exercise effect, the multifidus show greater activation in pelvic elevation (80.9 ± 21.4 x 58.5 ± 17.7 for the peak, p < 0.05, and 50.1 ± 17.6 x 34.5 ± 12.1 for the mean, p < 0.05). There was no difference between the exercises for the longuissimus. We conclude that the multifidus muscles are more requested in the hip thrust exercise and both show greater activation in the ascending phase.

A indústria automobilistica sempre enfrentou alguns obstáculos na montagem dos veículos, seja devido ao grande volume de pedidos, limitação da linha de montagem, dificuldades geradas por atrasos na entrega de insumos por fornecedores, e pelas multiplicidades oferecidas pelas próprias montadoras, nos opcionais disponíveis para cada modelo ou versão do veículo. O presente trabalho apresenta uma simulação com o propósito de beneficiar a linha de produção, com a eliminação de um dos gargalos presentes no processo de manufatura. A partir de simulações de uma linha em formato “U” acoplada na linha de montagem principal, onde os veículos são movidos para a linha suplementar, na qual efetuará a montagem dos tetos-solares. Sendo a simulação alicerçada a partir de tempos padrões na indústria automobilística disponibilizados em artigos científicos. Com a aplicação de uma linha de instalação adjunta de opcionais de baixa demanda pode-se analisar que existem ganhos consideráveis de tempo, viabilização da linha principal para manufatura de veículos sem o opcional, e possibilitando a diminuição de custos no volume total de opcionais vendidos.

A simple and low cost device (ca. US$ 150) that comprises two photodiodes fixed in lab-made Perspex flow cell is proposed for chemiluminescence measurements. The characteristics of the device (large observation window and reduced thickness) allow maximizing the amount of the emitted radiation detected. A sensitivity improvement of ca. 50 % was observed by employing two photodiodes for signal measurements. The performance of the device was assessed by the oxidation of luminol by hydrogen peroxide, yielding a linear response within the range of 2.50 to 500 µmol L-1 H2O2. The detection limit was estimated as 0.8 µmol L-1 hydrogen peroxide which is comparable with those obtained by using equipments based on photomultipliers.

An automatic flow analysis procedure for bromide determination in L-alanine aminoacid employing detection by chemiluminescence is described. The procedure was based on the bromide oxidation by chloramine-T followed by reaction with luminol. Spiking sample with standard solution gave recoveries values ranging from 94 to 106 %. Profitable features such as linear response ranging from 0.01 to 1.000 mg L-1 bromide (R = 0.999); detection limit of 8.9 µg L-1 Br-; relative standard deviation of 3.0% (n = 10); sampling throughput of 18 determination per hour; and reagent consumption 0.07 mg luminol and 0.4 mg chloramine-T per determination were achieved.

In this work an automatic flow procedure for L-alanine determination in the synthesis medium without a prior sample treatment is described. The method was based on oxidation of L-alanine by L-amino acid oxidize followed by the reaction of the H2O2 with luminol and chemiluminescence detection. In order to overcome the severe alkaline condition of the synthesis medium, a zone sampling strategy was employed for automatic sample dilution and pH adjustment. The procedure allows L-alanine determination in the range of 0.5 to 25.0 mmol L-1, a limit of detection of 0.08 mmol L-1 and a variation coefficient lower than 4% (n = 10). Other advantageous feature such as a sampling throughput of 44 determination per hour and low reagent consumption, 0.2 mg luminol and 16.4 mg hexacinoferrate(III) per determination, respectively, were also achieved.
