A inovação orientada à sustentabilidade é um assunto que se mostra cada vez mais pertinente e no qual muito se tem avançado em nível mundial. Além disso, empresa familiar é uma das configurações de empresa mais comuns no Brasil, portanto, é considerado relevante analisar o posicionamento das empresas familiares quanto à questão da sustentabilidade. O objetivo desse artigo é analisar, por meio de estudos de caso, a gestão estratégica da inovação orientada à sustentabilidade e sua relação com o modelo de negócio e o desempenho em empresas familiares. Para isso, foi levantado o perfil das empresas, analisada a postura estratégica e práticas de inovação sustentável por meio de dados qualitativos e verificada a relação da gestão estratégica da inovação sustentável com o modelo de negócios e o desempenho empresarial. Percebeu-se, então, que as empresas familiares demonstram incluir em seu planejamento estratégico ações pertinentes à sustentabilidade ambiental e social adotando práticas que demonstram isso. Também é possível perceber que essas empresas obtêm um retorno positivo dessas ações, o que é refletido em desempenho.

O texto apresenta uma reflexão sobre o papel da equipe gestora nas escolas da rede estadual de ensino do Rio Grande do Norte, a partir da Lei Complementar n. 585, de 30 de dezembro de 2016. A metodologia desenvolvida esteve pautada nas pesquisas bibliográfica e documental, as quais contribuíram para a compreensão das principais sistematizações presentes na Lei Complementar, instituída no contexto da rede estadual de ensino do Rio Grande do Norte. Como resultados, mediante a legislação sancionada pelo governo do Estado, foi possível perceber que: a) a equipe gestora das escolas estaduais é composta pelo diretor, vice-diretor, coordenador pedagógico e coordenador administrativo-financeiro; b) são muitas as atribuições para o desenvolvimento das atividades diárias, as quais apresentam desafios à dinâmica escolar; c) ainda não há uma democratização na escolha do coordenador pedagógico e do coordenador administrativo-financeiro, visto que estes são designados pelo diretor eleito; e, por fim, d) há contradições na Lei Complementar quando esta sinaliza a gestão democrática como concepção de gestão escolar, mas não democratiza todos os processos de escolha para a comunidade escolar.

Resumo A crescente preocupação dos stakeholders com a sustentabilidade motiva as empresas a adotar práticas que minimizem suas externalidades negativas. O objetivo do artigo é investigar o impacto da adoção de práticas de sustentabilidade no desempenho e na competitividade de indústrias brasileiras do setor moveleiro. Como práticas de sustentabilidade foram consideradas variáveis de gestão ambiental, práticas operacionais, práticas sociais para funcionários e para a comunidade. Os resultados indicaram relação positiva das práticas operacionais e sociais com o desempenho em sustentabilidade e com a competitividade. Contudo, tal comportamento não foi verificado para as práticas ambientais. O estudo evidencia como cada dimensão da sustentabilidade influencia no desempenho, motivando gestores para investir em práticas socioambientais, contribuindo para uma mudança sistêmica em prol da sustentabilidade. As evidências confirmam que o investimento em práticas de sustentabilidade melhora o desempenho e a competitividade das empresas.

Abstract Stakeholders' increasing concern with sustainability has been encouraging firms to adopt practices aimed at minimizing their negative externalities. The aim of the current article is to investigate the impact of adopting sustainability practices on the performance and competitiveness of the Brazilian furniture industry. Environmental management variables, operational practices, social practices focused on both the employees and the community were herein considered sustainability practices. Results have indicated the positive association of operational and social practices with sustainability performance and competitiveness. However, such behavior was not observed in environmental practices. The current study has shown the way each sustainability dimension influences performance by encouraging managers to invest in social and environmental practices, and by contributing to systemic changes on behalf of sustainability. Evidence has confirmed that investing in sustainability practices helps improving companies' performance and competitiveness.

Bauhinia scandens, an ornamental climbing vine, recently introduced in Brazil, in 2006 which has been gaining prominence due to its anti-tumor medicinal properties. A common feature amongst species of the Fabaceae family is dormancy due to the impermeability of the integument of the seed to water. The demand for seedlings of this species makes it necessary to elucidate the germination process and initial seedling growth. The objective of this study was to determine a method to overcome dormancy, thereby promoting seed germination and initial growth of B. scandens seedlings. The seeds were subjected to one of four treatments, besides the control: mechanical scarification, immersion in water (26 °C for 24 hours), immersion in hot water (86 °C for 24 hours, then 26 °C) and immersion in H2SO4 (95%) for 15, 30, 45, and 60 minutes. The seeds were evaluated for water content, germination (normal, abnormal seedlings, dormant and dead seeds), first count, mean germination time and relative frequency of germination. The seedlings were evaluated for emergence in sand, first count, emergence speed index, length and dry matter mass. B. scandens seeds should be immersed in H2SO4 for 45 and 60 minutes before sowing to overcome dormancy, in order to promote and standardize seed germination and enhance initial growth of the seedlings.

Forage pea is an important annual, cold climate crop with high levels of essential amino acids in its seeds, which are lacking in the composition of cereal grains. Therefore, livestock farmers use its seeds as a nutritious source of forage. To plant fields of this forage, it is necessary to know the quality of the seeds, determined through germination and vigor tests. In the literature, studies on vigor tests for forage pea seeds are scarce. This study aimed to verify the efficiency of vigor tests, with emphasis on accelerated aging to evaluate the physiological quality of forage pea seeds in order to select lots for seedling emergence in the field. Using accelerated aging tests, 10 lots of forage pea were evaluated for moisture content, thousand-seed weight, emergence percentage, emergence first count, speed index of seedlings in the field, germination, germination first count, and electrical conductivity. The following variations of methodology were used: temperatures of 41 and 42 °C, exposure times of 48 and 72 h, and different relative humidity values in the aging atmosphere, using distilled water (100 % RH), saturated solution of potassium chloride (87 % RH), and sodium chloride (76 % RH). The tests of germination, emergence first count of seedlings in the field, emergence speed index, and electrical conductivity are promising to evaluate the vigor of forage pea seed lots. The accelerated aging test conducted in a solution saturated with potassium chloride at 42 °C for 48 h is adequate to estimate the vigor of forage pea seed lots, providing information similar to that of the emergence of seedlings in the field.

The period of 21 days suggested by the Brazilian Rules for Seed Testing for the germination test of B. humidicola seeds seems too long for seed producing companies and laboratories since they depend on the results for decisions concerning the storage or the commercialization of the seed lots. So, the objective of this work was to evaluate the possibility of getting germination results of B. humidicola seeds in a shorter period. The procedures consisted in submitting the seeds to a dormancy breaking treatment and to alternating temperatures during the germination test. Seed samples of nineteen S1 and S2 seed lots were submitted to the following treatments: moistening the germination substratum with 1) deionized water (check treatment), 2) a KNO3 (0.2%) solution, and 3) scarifying the seeds with sulfuric acid for 10 minutes. The germination test was conducted under the conditions of 1) alternating temperatures of 20 and 35 °C and 2) alternating temperatures of 15 and 35 °C both with 8 hours of light. Normal seedlings were evaluated in daily countings. The results showed that the germination test of B. humidicola seeds may be carried out under alternating temperatures of 15 and 35 °C without breaking seed dormancy with a final evaluation of the germination 10 days after the sowing of the seeds.

Bauhinia scandens has potential importance as an ornamental and medicinal plant. Researchers have isolated and identified 1-O-alkylglycerol in the leaves of the B. scandens plant, and established antitumor properties using the Brine Shrimp toxicity test, an internationally accepted bioassay. Although this species has high potential, little is known about the viability of seedling production and the morphology of these plants, particularly in terms of seed characteristics and initial stages of germination. The objective of this study was to characterize the seed morphology, germination, and seedlings of B. scandens. Seed water content, weight, and coloration were evaluated. This study also included a description of seed biometrics, external and internal structures, germination, and seedling morphology. Internal seed morphology was evaluated by the anatomical sectioning and X-ray methods. The morphology data obtained were subjected to descriptive statistical analysis and germination data were determined using Cramér's V. B. scandens seeds have a coloration ranging from very dark grayish-red to dark reddish-brown, flat oblong shapes, and rounded bases and apexes with full or slightly undulating margins. Healthy seedlings are produced mainly by seeds with well-formed internal structures. The reddish petiole of the seedling leaves is a taxonomic character for B. scandens identification. The non-domestication and genetic variability of this species reflect on the seed and seedling color and size variation.

White oats are cereals that are grown in different regions of the globe because they have good adaptability and final destination. Thus, their cultivation has shown significant increases in order to meet demand, especially for forage production, grains, and animal and human consumption. High-quality seeds are necessary for crop cultivation and white oats are sown in winter when thermal fluctuations may occur. Therefore, the objective of this study was to evaluate the physiological changes in oat seeds exposed to different temperatures during the germination phase. The experiment was a completely randomized design with four replications in a 6 × 4 factorial design. Six cultivars were evaluated: Aphrodite, Altiva, Artemis, Brava, Corona, and Guará at temperatures of 15, 20, 25, and 30 °C, and the following measurements were taken: first germination count, germination, germination speed index (IVG), and seedling length and mass. The results were analyzed using analysis of variance (F test) and the means were compared using Tukey's test. The cultivars were physiologically affected at the minimum and maximum temperatures. At 15 °C, normal seedlings did not form, whereas the highest germination values were recorded at 20 and 25 ºC, which showed that these temperatures were the most favorable temperatures for the germination process. Vigor declined at 30 °C and there was a greater number of abnormal seedlings and dead seeds.
