Background: Kombucha is an increasingly consumed product classified as a nutraceutical. Legislative efforts about these products remain confusing and without global harmonization. This natural product has been developed to improve or promote physical and mental health. However, it needs regulatory guidelines to control the production and guarantee the product's efficacy and safety. Aim: The study intends to draw attention to the need for regulatory guidelines and the potential of this product in the market and peoples' health. Key findings and conclusions: The lack of regulation and the low level of literacy about this product can limit its development, marketing, and impact on health. Thus, it is essential to highlight the potential value of this product and invest in its development and marketing. Likewise, it is important to spread awareness among the population of these products and their impacts on people's health. Thus, this study focuses on a pertinent theme and alerts to the need for legislation for these products, to draw attention to the inexistent legislative control and the consequent need for regulatory guidelines for better and safer production and consumption. ; info:eu-repo/semantics/publishedVersion

In the academic agenda and in international organizations, the strength or fragility of states is a relevant thematic, especially in light of geopolitical changes and security issues in recent decades. While the concept of state refers to the methods of control that a government employs to manage a given territory, which refers to regimes and forms of government, the fragility of states, as well as concerns of the international community motivated by incapacities, generates a loss of legitimacy internal politics, leading to possible regional collapses and instabilities, the capacity for action is then seen as linked to political legitimacy, which is nourished by the confidence conferred on the internal and external levels. In this context, this work seeks to articulate some theoretical propositions in an attempt to broaden the view on the phenomenon of statehood and its relations with political legitimacy, such propositions are then guiding to a comprehensive model at the end of the article. In this sense, this essay presents as a general proposition: Political Legitimacy, constituent of Statehood, in its relations with regimes and forms of government, and with the trust attributed to political actions, is an intervening factor in Fragility manifest in the States.

O objetivo deste estudo foi analisar, de forma comparativa, os impactos da norma de responsabilidade social empresarial e a discriminação das mulheres negras, na indústria de transformação sergipana. Para tanto, foram utilizados os microdados da Relação Anual de Informações Sociais (RAIS) do Ministério do Trabalho e Emprego (MET) de 2007/2008 e 2013/2014. A partir da análise dos dados, nota-se, em relação à discriminação de gênero, uma tendência à predominância masculina no setor da indústria de transformação sergipana. Os dados indicam também que não apenas o sexo feminino é aquele com menor presença no setor industrial, mas é a mulher de cor preta que possui os menores percentuais de inclusão no setor industrial sergipano. Esse cenário comparativo de discriminação de gênero e raça pouco se alterou com a introdução da norma de responsabilidade social empresarial, a partir da década de 1990.

The changing demographic structure of the population, resulting in unparalleled growth of the elderly population, means that e-inclusion of this population group is considered to be a social and political priority in the context of the Information Society. Most research studies have only considered individual variables -such as age, gender, education, income and health- in the explanatory models of e-inclusion of senior citizens, while ignoring macro variables, such as the welfare systems and public policies in each country. Simultaneously, most studies focus on small-scale samples, lack international comparisons and do not consider the combined effect of several variables that influence Internet use. This study aims to analyse possible differences between two countries that have different welfare systems and public policies, after controlling for the effects of the individual variables that have been identified in the literature as relevant for Internet use. The study focuses on a sample of 8639 individuals, aged 50 years and over, residing in Portugal and Estonia, who participated in the SHARE project (Survey of Health, Ageing and Retirement in Europe). The results of the logistic regression analysis demonstrate that welfare systems and public policies have an impact on the likelihood of Internet use, thus reinforcing the importance of developing public policies to foster e-inclusion of senior citizens. ; This paper uses data from SHARE Wave 4 (DOI:10.6103/SHARE.w4.500), see Borsch-Supan et al. (2013) for methodological details.* The SHARE data collection has been primarily funded by the European Commission through FP5 (QLK6-CT-2001-00360), FP6 (SHARE-I3: RII-CT-2006-062193, COMPARE: CIT5-CT-2005-028857, SHARELIFE: CIT4-CT-2006-028812) and FP7 (SHARE-PREP: No211909, SHARE-LEAP: No227822, SHARE M4: No261982).

Este estudo teve como objetivo caracterizar a macrofauna associada às galerias perfuradas por Neoteredo reynei em toras de Rhizophora mangle em uma área de manguezal do estuário do rio Mojuim (São Caetano de Odivelas, Pará). As coletas foram realizadas em três ocasiões do período menos chuvoso (junho, julho e agosto de 2004), na zona de médio-litoral em três sítios de amostragem. Em cada ocasião, foi retirada, de cada sítio, uma tora de R. mangle em estado inicial de decomposição. Paralelamente à coleta biológica, foram registrados a temperatura do ar, o pH, a salinidade e a temperatura da água. Neoteredo reynei foi a única espécie de Teredinidae presente nas amostras. A macrofauna associada às suas galerias foi composta por um total de 452 indivíduos, distribuídos em 31 táxons pertencentes aos filos: Nemertea (um táxon), Mollusca (três táxons), Annelida (seis táxons) e Arthropoda (21 táxons). A composição da fauna registrada foi tipicamente estuarina, com exceção de alguns grupos terrestres. Os descritores biológicos (abundância, riqueza, diversidade e equitatividade) aumentaram seus valores ao longo dos meses, como provável reflexo do aumento da salinidade no estuário. A diversidade da macrofauna registrada no interior das toras reflete a importância deste nicho para os organismos e, consequentemente, para o funcionamento do ecossistema manguezal.

"Portugal in the 21st Century provides a thorough yet accessible picture of contemporary Portugal in the first two decades of the twenty-first century. It examines and elucidates Portugal's recent trajectory, its current position, and the main challenges it faces through an examination of the principal dimensions of cultural, economic, political, and social development in the country. Bringing together some of the foremost Portuguese experts in each of these areas, it draws on a diverse knowledge across the social sciences and humanities - including anthropologists, art historians, economists, historians, legal scholars, literary scholars, political scientists, biologists, and sociologists - to create a multidimensional portrait of contemporary Portuguese society. Key features: Organised into nine substantive chapters - each of which covers a major area of Portugal's contemporary existence - from its national identity and political system to its economy, scientific, literary, and artistic production. Opens with a general introduction providing historical context, and a chapter on Portuguese national identity. Thematic chapters focus on social, political, economic, and cultural developments of the last two decades. This book provides a comprehensive, erudite yet accessible introduction to contemporary Portugal and is essential reading for students, scholars, and readers interested in Portugal, Portuguese and Southern European politics and culture, Iberian, or Iberian-American studies and more broadly to European and Comparative Politics"--

A concepção da lógica dominante de serviço pode ser compreendida a partir do contexto do ensino superior. Em um ambiente de sala de aula, alunos e professores podem cocriar valor contribuindo para um melhor aproveitamento das disciplinas e, consequentemente, maior engajamento dos alunos e melhor resultado para as universidades. Nesse sentido, o objetivo do presente estudo foi analisar o efeito da cocriação de valor em sala de aula como um antecedente do engajamento de estudantes do ensino superior. A partir de uma amostra de 320 estudantes de universidades da região sul do Brasil e utilizando-se de modelagem de equações estruturais, os resultados apontaram que a cocriação de valor aumenta o engajamento dos estudantes com a disciplina. As descobertas também forneceram apoio empírico, demonstrando que o tipo de metodologia aplicada pelo professor exerce um papel moderador na relação entre a coprodução e o engajamento do aluno com a disciplina. Os resultados têm implicações para as universidades e para os professores ao instigar o desenvolvimento de metodologias que sejam centradas na cocriação de valor do aluno.

A proposta deste ensaio consistiu em refletir sobre os impactos epistemológicos e práticos que o desenvolvimento da Data Science trouxe para a área de marketing, focando a discussão em torno do conceito de marketing analytics. Neste ensaio teórico, defendemos a posição de que marketing analytics decorre de um diálogo interdisciplinar entre marketing e Data Science com impactos na prática gerencial de marketing. Também entendemos que, em termos epistemológicos, a lógica abdutiva está subjacente ao marketing analytics. Sendo assim, essa vertente, com preceitos epistemológicos e operacionais distintos do convencional, também tem potencial de revolucionar o universo acadêmico, e consequentemente, o pensamento e a prática de pesquisa em marketing, apontando para novas oportunidades de construção de conhecimento, baseada em dados intensivos e em métodos mais flexíveis.

Curricular internships are increasingly seen as an effective strategy capable of contributing to the objectives and targets of the sustainable development paradigm, both in its social, economic and institutional dimensions. This positive outlook is ingrained within the large bulk of existing research, which has been focused on the discussion of positive outputs, such as the enhancement of graduates′ competences (employability) and their work integration (employment). An important, albeit relatively unexplored, feature of the sustainable institutional politics of curricular internship management pertains to the assessment of its associated liabilities and tensions. This article seeks to address this challenge, by analyzing two interrelated dimensions. First, it seeks to understand the internship processes ranging from the planning to the implementation stages. Second, it elicits the associated negative aspects (the 'lunar side') of internships, allowing for an assessment of the features where there is room for improvement. Empirically, this article draws on in‐depth qualitative research. It presents the results of four focus groups, voicing the perceptions of top management structures and students involving first cycle degrees in the areas of Marketing, Management, and Accounting from four public Portuguese Higher Education Institutions (HEIs)‐three polytechnics and one university. Findings confirm the general positive outlook of internships. Perceived negative perspectives report to both internal problems (such as the lack of institutional support and curricular design) and external problems (e.g., the shortage of suitable internship placements), constituting barriers towards sustainable institutional policies and strategies. Adaptive strategies to overcome specific difficulties are highlighted (e.g., establishment of advisory committees with local businessmen). Finally, recommendations regarding curricular internship management at HEIs are delineated (e.g., investment in monitoring and evaluation strategies of ...
