Therefore, the present study aims to explore the factors related to the time of diagnosis of CC (recent/non-recent), the barriers to participation and academic success (health condition, people's attitude towards CC and school physical environment), the physical and mental health (physical/psychological symptoms and concerns) and school-related variables (relationship with teachers and peers), regarding the school participation of first-year students with CC. This work is part of the HOUSE-Colégio F3 Project, University of Lisbon, which includes 1143 first-year university students from 17 Faculties and Institutes of the University of Lisbon. In this specific study, only the subsample of 207 students with CC was considered, 72.4% of which were female, aged between 18 and 54 years (M = 20.00; SD = 4.83). The results showed that students with a recent diagnosis of CC and students with school participation affected by the CC were those who presented more negative indicators regarding barriers to school participation, physical and mental health, and school-related variables. A greater impact of CC in terms of school participation was associated with having a recent diagnosis, with people's attitude towards CC and with the health condition as barriers, with more psychological symptoms and worse relationships with teachers and peers. This is a relevant message for the organization of health services for students with CC at the beginning of their university studies, especially since they are often displaced from home and managing their health conditions alone (in many cases, for the first time)., Ana Cerqueira—Foundation for Science and Technology (FCT) Grant (SFRH/BD/148403/2019).

Application of municipal sewage sludge to agricultural land, especially in shallow soils, demands to validate the maximum amount ofheavymetal, monitoring its effects on soil and on crops. To achieve this goal, four farms, considered replicates, were chosen in Castro Verde region, to apply four experimental treatments (T1 – conventional fertilization (CF); T2 – subsoiling (S) + (CF); T3 – (S) + (CF) + sludge injection (SI) and T4 – (S) + recommended fertilization (RF) + (SI)), to get mixing effects of sludge injection with fertilization modalities. They were sown wheat (Triticum aestivum) and oat (Avena sativa) as test crops, and sewage sludge, containing heavy metals level according to law (MAOTDR, 2009), was furnished by Castro Verde sewage treatment plants. Results did not show any soil pollution by the metals Cd, Cr, Ni, Pb, Cu, Zn and Hg, and the treatments did not affect significantly (p>0.05) the crops. This study validated, at these particular conditions,heavymetals limits established by law to avoid health and environmental risks., A valorização agrícola de lamas de ETAR (lamas residuais urbanas), através da sua aplicação ao solo, em especial numa zona com solos de pouca espessura, exige que se validem os limites considerados tóxicos de metaispesados, em relação ao solo e a culturas. Para a execução do objetivo em estudo foram selecionadas quatro explorações na área cerealífera de Castro Verde, às quais foram aplicados os tratamentos experimentais (T1- adubação tradicional (AT); T2- ripagem (R) + AT; T3 – R +AT+ injeção de lamas (IL) e T4 – R + adubação recomendada + IL), onde se pretendeu além de verificar o efeito da injeção de lamas, relacioná-la com modalidades de fertilização. Em três das explorações foi semeado trigo mole (Triticum aestivum)e numa delas semeou-se aveia (Avena sativa). Utilizou-se uma lama, proveniente da ETAR de Castro Verde, por apresentar níveis de microrganismos e teores de metaispesados*abaixo dos limites estabelecidos por lei (Decreto-Lei n.º 276/2009). Os resultados revelaram que a aplicação de lamas, com elevado teor de humidade, não poluiu o solo em Cd, Cu, Ni, Pb, Cr, Zn e Hg. Em todas as explorações os teores detetados destes metais, em todos os tratamentos, foram inferiores aos limites de concentração inaceitáveis. Os tratamentos também não provocaram diferenças significativas (p> 0,05) sobre os teores de metaispesadosdoseados nas culturas.

Agriculture is one of the obvious targets for recycling "sewage sludge" from WWTP, because of its potential in the physical, chemical and biological correction of agroforestry soils, being an advantageous option if it is ensured - by an analysis performed by a legal entity - that its application is allowed. This analysis, in addition to being an indicator of a possible harmful effect on the environment and on the targeted crop (preventing its use), makes it possible to assess the most adequate amount to be applied in each case, and the remaining deficiencies to be supplied by the chemical fertilization., A agricultura é um dos alvos óbvios na reciclagem das “Lamas de Depuração” das ETAR, pela sua potencialidade na correção física, química e biológica dos solos agro-florestais, podendo constituir uma opção muito vantajosa se for garantida - por análise efetuada por entidade idónea - que a sua aplicação é legal, tendo em conta a legislação vigente. Esta análise, para além de constituir um indicador de um eventual efeito nocivo para o ambiente e para a cultura (impeditivo da sua utilização), permite avaliar as dotações mais adequadas e eventuais carências remanescentes, em cada caso, sendo imprescindível face à variabilidade da composição das lamas.

La internacionalización de las empresas familiares se ha convertido en un campo relevante de la investigación económica, susceptible de ser abordado desde diferentes enfoques teóricos. En todos ellos, la perspectiva histórica es una herramienta muy útil, ya que un enfoque de largo plazo permite un conocimiento más profundo del proceso de internacionalización y de sus implicaciones geográficas, económicas y sociales. El propósito de este trabajo es indagar en los procesos de internacionalización seguidos por las empresas familiares, poniendo el énfasis en los factores que favorecen su éxito en el mercado mundial. En particular, presentamos un análisis histórico económico de tres empresas familiares relevantes en la historia del negocio del corcho a nivel mundial; primero, la empresa familiar Reynolds, que constituye un paradigma de éxito comercial en el negocio corchero hasta el último cuarto del siglo XIX, y de fracaso a partir de entonces; segundo, la empresa Mundet & Sons, que, a pesar de haber llegado a ser una empresa líder en el negocio corchero mundial, constituye también un ejemplo de fracaso paradigmático por su desenlace final en la década de 1980; y tercero, la empresa Corticeira Amorim, ejemplo de éxito y de liderazgo en el mercado internacional desde mediados del siglo XX hasta hoy. The internationalization of family firms has become an important field of economic research, which could be addressed from different theoretical approaches. In all of them, historical perspective is a very useful tool, since a long-term approach allows a deeper understanding of the internationalization process and their geographic, economic and social implications. The purpose of this work is to analyze the processes of internationalization followed by family firms, with an emphasis on factors linked to them which favor their success in the global markets. In particular, we present a historical analysis of three relevant family firms in the world cork business history; first, the Reynolds family firm, which is a paradigm of commercial success in the cork business until the last quarter of the nineteenth century, and of failure thereafter; second, the Mundet & Sons company, which, despite having become a leading company in the world cork business, is also a paradigmatic example of failure because of its final outcome in the 1980s; and third, Corticeira Amorim, an example of success and leadership in the international market since the mid-twentieth century to today.
