Life cycle assessment and eco-innovations: What kind of convergence is possible?

Generation of goods and services are highly dependent on the use of natural resources. Until very recently, there was an implicit belief that the physical expansion of the economic system could be unlimited, as if the planet would have conditions and time enough to recover and continue to supply resources. This belief implies a confidence in an economic system that would provide whatever is necessary for a continuous growing production and consumption. Even believing that technology alone is not enough to solve the current environmental problems, it is certain that it can collaborate to mitigate climate change and to adaptation to changes in the environment. By bringing environmental aspects into discussions, eco-innovations can affect and transform the innovation system in order to create sustainable processes. However, the main challenge towards the transition to a more sustainable, cleaner and more equitable society is to set innovation in a new context, as until very recently it only considered the economic variables. This change means to value the social and environmental dimension of the innovation. In addition to eco-innovation, Life Cycle Assessment (LCA) is spreading in the industrial environment, offering promising perspectives. LCA is considered a valuable methodology in the environmental sustainability of industry. In this context, the present study addresses LCA and its relationship with the generation of eco-innovations. Drawing on contributions from literature on eco-innovation and LCA, the paper analyses available evidence on this relationship in a context of the transition towards sustainable development. To structure the debate, the paper offers a conceptual approach and an illustrative case on international researchers' and practitioners’ perceptions on the potentially positive relationship between eco-innovation and LCA. The study gathers data in the Web of Science (WoS) Core Collection and in Scopus, in order to provide a picture of the distribution of documents retrieved from these databases, dealing with both eco-innovation and LCA topics. The paper concludes that the convergence of the eco-innovation and LCA studies is quite plausible, but at least in its initial phase, the literature that unites both themes is scarcely found in publications in the area of innovation, being more frequent in the area of engineering and management that usually addresses LCA studies

Sempre alerta para servir: a importância das tecnologias na dinâmica do escutismo

Numa era em que a tecnologia está tão presente na vida das pessoas, o movimento escutista não é excepção. Ainda que o método escutista possa não fomentar a utilização frequente da tecnologia, os destinatários do método, crianças e jovens, são hoje nativos digitais que convivem diariamente com as TIC e social media. Deste modo, importa perceber qual o papel das tecnologias na dinâmica do escutismo em dois níveis: na aproximação dos jovens ao método escutista e na sua utilização para rentabilizar o tempo disponível para a preparação e realização das actividades. Para tal, a investigação levada a cabo, composta por duas fases, exploratória e inferencial, permitiu a recolha de dados, com recurso à aplicação de um questionário, a 264 participantes. Os dados recolhidos permitiram concluir que se reconhece a importância e utilização das TIC e social media, contudo não são o meio preferencial para por em prática as actividades e transmitir a informação, nomeadamente ao nível do sistema de progresso. A utilização das TIC e social media por parte do movimento escutista, poderá facilitar a aplicação do método escutista, sem descuidar a sua essência, não se trata de substituir as actvidades escutistas por tecnologia, mas utilizar a tecnologia em prol das actividades que são essenciais ao desenvolvimento dos jovens, que são os adultos do futuro. Trata-se de melhorar as condições em que estamos "Alerta", para Servir melhor.In an age where technology is so present in people's lives, the scout movement is no exception. Although the scout method may not encourage frequent use of technology, the method's target, children and young people, are today digital natives that coexist daily with ICT and social media. In this way, it is important to understand the role of technologies in the dynamics of scouting at two levels: the approach of young people to the scout method and its use to monetize the time available to prepare and make the activities. To do so, the investigation, which consisted of two phases, exploratory and inferential, allowed the data collection, through a questionnaire, with 264 participants. The data collected allowed to conclude that the importance and use of ICTs and social media are recognized, but they are not the preferred means of putting the activities into practice and transmitting information, especially at the level of the progress system. The use of ICT and social media by the scout movement, may facilitate the application of the scout method, without neglecting its essence, it is not a matter of replacing the scouts activities by technology, but using technology in favor of the activities that are essential to the young people, who are the adults of the future. It is about improving the conditions in which we are "alert" to better serve

A parallel metaheuristic for large mixed-integer dynamic optimization problems, with applications in computational biology

[Abstract] Background: We consider a general class of global optimization problems dealing with nonlinear dynamic models. Although this class is relevant to many areas of science and engineering, here we are interested in applying this framework to the reverse engineering problem in computational systems biology, which yields very large mixed-integer dynamic optimization (MIDO) problems. In particular, we consider the framework of logic-based ordinary differential equations (ODEs). Methods: We present saCeSS2, a parallel method for the solution of this class of problems. This method is based on an parallel cooperative scatter search metaheuristic, with new mechanisms of self-adaptation and specific extensions to handle large mixed-integer problems. We have paid special attention to the avoidance of convergence stagnation using adaptive cooperation strategies tailored to this class of problems. Results: We illustrate its performance with a set of three very challenging case studies from the domain of dynamic modelling of cell signaling. The simpler case study considers a synthetic signaling pathway and has 84 continuous and 34 binary decision variables. A second case study considers the dynamic modeling of signaling in liver cancer using high-throughput data, and has 135 continuous and 109 binaries decision variables. The third case study is an extremely difficult problem related with breast cancer, involving 690 continuous and 138 binary decision variables. We report computational results obtained in different infrastructures, including a local cluster, a large supercomputer and a public cloud platform. Interestingly, the results show how the cooperation of individual parallel searches modifies the systemic properties of the sequential algorithm, achieving superlinear speedups compared to an individual search (e.g. speedups of 15 with 10 cores), and significantly improving (above a 60%) the performance with respect to a non-cooperative parallel scheme. The scalability of the method is also good (tests were performed using up to 300 cores). Conclusions: These results demonstrate that saCeSS2 can be used to successfully reverse engineer large dynamic models of complex biological pathways. Further, these results open up new possibilities for other MIDO-based large-scale applications in the life sciences such as metabolic engineering, synthetic biology, drug scheduling.Ministerio de Economía y Competitividad; DPI2014-55276-C5-2-RMinisterio de Economía y Competitividad; TIN2016-75845-PGalicia.

Intersetorialidade e potenciais conflitos de interesse entre governos e setor privado comercial no âmbito das ações de alimentação e nutrição para o enfrentamento de doenças crônicas não transmissíveis | Intersectoriality and potential conflicts of interest between governments and private, commercial sector within the context of food and nutrition actions to deal with chronic non-communicable diseases

Neste artigo foram analisados os potenciais conflitos entre interesses governamentais e privados de caráter comercial em torno das ações de alimentação e nutrição (AN) no âmbito de propostas intersetoriais de enfrentamento das DCNT no Brasil. Para tal, foram identificados artigos acadêmicos e documentos institucionais publicados a partir de 2000 que abordassem as ações de AN em políticas de DCNT pautadas pela intersetorialidade. Foram priorizados elementos que contribuíssem para a compreensão dos potenciais conflitos de interesse entre governos e o setor privado comercial no âmbito de estratégias intersetoriais de enfrentamento de DCNT. Concluiu-se que o princípio da intersetorialidade, desassociado de um processo político que problematize os critérios de eleição e as práticas institucionais dos setores que respondem pelo conjunto de ações que compõe as políticas governamentais, pode servir como facilitador do favorecimento de interesses comerciais. A participação no processo decisório de setores de interesse comercial cujas práticas ferem objetivos e princípios das políticas públicas, movidos pela expansão da demanda por seus produtos e pela concentração progressiva de poder, pode retardar, atenuar ou impedir ações efetivas na redução de DCNT. Esta possibilidade é particularmente relevante no âmbito de atribuições que são próprias aos entes Estatais, especialmente as estratégias regulatórias. ------------------------------------------------------------------------------------------- This article analyzed the potential conflicts of interest between government and private commercial sectors in the area of food and nutrition (FN) activities within the context of intersectoral proposals for dealing with chronic non-communicable diseases (CNCD) in Brazil. To this end, academic articles and institutional documents published after 2000 were identified that addressed FN actions in CNCD policies guided by intersectoriality. Elements that contributed to understanding the potential conflicts of interest between governments and the private, commercial sector within the context of intersectoral strategies to deal with CNCD were prioritized. It was concluded that the principle of intersectoriality disassociated from a political process that complicates the eligibility criteria and institutional practices of the sectors responsible for the set of actions that comprise government policies may serve as facilitators for favoring commercial interests. Participation in the decision-making process of the sectors of commercial interest whose practices, driven by increased demand for their products and the progressive concentration of power, contradict the purposes and principles of public policy, may delay, reduce, or prevent effective actions to reduce CNCD. This possibility is particularly relevant in the context of attributions that are specific to government entities, especially regulatory strategies

Climate change and impact on renewable energies in the Azores strategic visions for sustainability

The energy sector is the largest contributor to global greenhouse gas emissions, but could also be seriously affected by climate change, calling into question society’s current consumption patterns. In this communication, climate projections based on a set of numerical models of global circulation are used to simulate the climate until the end of the century and keep in mind the alternative scenarios of pollutant emissions. Apart from solar energy, the results for the Azores region show a negative impact on the production and consumption of renewable energies. In the regional context, this issue assumes special relevance, given the geographical constraints, such as territorial discontinuity and insularity. Based on these assumptions, measures and recommendations are pointed out for the sectors that most penalize greenhouse gas emissions, considering the energy sustainability in the Azores and the commitments and goals assumed under international agreements.info:eu-repo/semantics/publishedVersio

Reliability and validity of the geriatric depression scale in a sample of portuguese older adults with mild-to-moderate cognitive impairment

Although the Geriatric Depression Scale (GDS) is a well-established instrument for the assessment of depressive symptoms in older adults, this has not been validated specifically for Portuguese older adults with cognitive impairment. The objective of this study was to analyze the psychometric properties of two Portuguese versions of the GDS (GDS-27 and GDS-15) in a sample of Portuguese older adults with mild-to-moderate cognitive impairment. Clinicians assessed for major depressive disorder and cognitive functioning in 117 participants with mild-to-moderate cognitive decline (76.9% female, Mage = 83.66 years). The internal consistency of GDS-27 and GDS-15 were 0.874 and 0.812, respectively. There was a significant correlation between GDS-27 and GDS- 15 with the Beck Depression Inventory-II (GDS-27: rho = 0.738, p < 0.001; GDS-15: rho = 0.760, p < 0.001), suggesting good validity. A cutoff point of 15/16 in GDS-27 and 8/9 in GDS-15 resulted in the identification of persons with depression (GDS-27: sensitivity 100%, specificity 63%; GDS-15: sensitivity 90%, specificity 62%). Overall, the GDS-27 and GDS-15 are reliable and valid instruments for the assessment of depression in Portuguese-speaking older adults with cognitive impairmentS

Tracking the Origin of a Rabbit Haemorrhagic Virus 2 Outbreak in a Wild Rabbit Breeding Centre in Portugal; Epidemiological and Genetic Investigation

As key prey, the wild rabbit downsize constitutes a major drawback on the endangered Iberian lynx (Lynx pardinus) re-introduction in the Iberia. Several captive breeding units mostly located in Alentejo, endeavour the wild rabbit repopulation of depleted areas assigned for the lynx re-introduction. Here we report an RHDV2 outbreak that occurred in early 2016 in a wild rabbit captive breeding unit located in Barrancos municipality. The estimated mortality rate between March and April 2016 was approximately 8.67%. Anatomopathologic examination was carried out for 13 victimized rabbits. Molecular characterization was based on the complete vp60 capsid gene. The 13 rabbit carcasses investigated showed typical macroscopic RHD lesions testing positive to RHDV2- RNA. Comparison of the vp60 nucleotide sequences obtained from two specimens with others publically available disclosed similarities below 98.22% with RHDV2 strains originated in the Iberia and Azores and revealed that the two identical strains from Barrancos-2016 contain six unique single synonymous nucleotide polymorphisms. In the phylogenetic analysis performed, the Barrancos-2016 strains clustered apart from other known strains, meaning they may represent new evolutionary RHDV2 lineages. No clear epidemiological link could be traced for this outbreak where the mortalities were lower compared with previous years. Yet, network analysis suggested a possible connection between the missing intermediates from which the strains from Barrancos 2013, 2014 and 2016 have derived. It is therefore possible that RHDV2 has circulated endemically in the region since 2012, with periodic epizootic occurrences. Still, six years after its emergence in wild rabbits, RHDV2 continues to pose difficulties to the establishment of natural wild rabbit populations that are crucial for the self-sustainability of the local ecosystems
