Household consumption patterns and income inequality in EU countries: Scenario analysis for a fair transition towards low-carbon economies

The growing awareness of the current and future consequences of climate change has led to a range of international commitments aimed at ensuring sustainable development as part of the United Nations Framework Convention on Climate Change, and the Paris Agreement. These agreements reflect a concern of how to reduce carbon emissions and the pathway towards environmental improvement. Recent literature has pointed out the role of households as direct and indirect drivers of environmental impacts and as key agents in achieving low carbon economies and climate-resilient development. Disparities in income distribution and lifestyles within and among countries, however, entail a different starting point for each country to reach sustainable pathways. The EU is fully committed to delivering on the United Nations 2030 Agenda and its implementation. Inequality continues to be a significant concern, reflected in the UN''s Sustainable Development Goals. In this context, we explore the relationships between household consumption patterns in the EU, income inequality, and global carbon emissions trends, using an environmentally extended multiregional and multisectoral input-output model. We study the trends in global carbon emissions associated with the different household consumption patterns and income categories over 15 years, and evaluate the role of income distribution, consumption patterns, and technological conditions by country and income group. Additionally, we study, through certain scenarios, the potential achievement of double dividends, by alleviating poverty and reducing emissions

Polymorphisms in the MTHFR gene influence embryo viability and the incidence of aneuploidy

MTHFR is an important enzyme in the metabolism of folic acid and is crucial for reproductive function. Variation in the sequence of MTHFR has been implicated in subfertility, but definitive data are lacking. In the present study, a detailed analysis of two common MTHFR polymorphisms (c.677C>T and c.1298A>C) was performed. Additionally, for the first time, the frequencies of different MTHFR alleles were assessed in preimplantation embryos. Several striking discoveries were made. Firstly, results demonstrated that maternal MTHFR c.1298A>C genotype strongly influences the likelihood of a pregnancy occurring, with the 1298C allele being significantly overrepresented amongst women who have undergone several unsuccessful assisted reproductive treatments. Secondly, parental MTHFR genotypes were shown to affect the production of aneuploid embryos, indicating that MTHFR is one of the few known human genes with the capacity to modulate rates of chromosome abnormality. Thirdly, an unusual deviation from Hardy-Weinberg equilibrium was noted for the c.677C>T polymorphism in subfertile patients, especially those who had experienced recurrent failure of embryo implantation or miscarriage, potentially explained by a rare case of heterozygote disadvantage. Finally, a dramatic impact of the MTHFR 677T allele on the capacity of chromosomally normal embryos to implant is described. Not only do these findings raise a series of interesting biological questions, but they also argue that testing of MTHFR could be of great clinical value, identifying patients at high risk of implantation failure and revealing the most viable embryos during in vitro fertilisation (IVF) cycles

Effect of age and severity of cognitive dysfunction on spontaneous activity in pet dogs - Part 1: Locomotor and exploratory behaviour

Age-related cognitive dysfunction syndrome (CDS) has been reported in dogs and it is considered a natural model for Alzheimer’s disease in humans. Changes in spontaneous activity (including locomotor and exploratory behaviour) and social responsiveness have been related to the age and cognitive status of kennel-reared Beagle dogs. The aim of this study was to assess the influence of age and severity of CDS on locomotor and exploratory behaviour of privately owned dogs. This is the first part of a two-part report on spontaneous activity in pet dogs. An open-field (OF) test and a curiosity test were administered at baseline and 6 months later to young (1–4 years, n = 9), middle-aged (5–8 years, n = 9), cognitively unimpaired aged (⩾9 years, n = 31), and cognitively impaired aged (⩾9 years, n = 36) animals. Classification of cognitive status was carried out using an owner-based observational questionnaire, and in the cognitively impaired group, the dogs were categorised as having either mild or severe cognitive impairment. Dogs were recorded during sessions in the testing room and the video-recordings were subsequently analysed. The severity of CDS (but not age) influenced locomotion and exploratory behaviour so that the more severe the impairment, the higher the locomotor activity and frequency of corner-directed (aimless) behaviours, and the lower the frequency of door-aimed activities. Curiosity directed toward novel stimuli exhibited an age-dependent decline although severely affected animals displayed more sniffing episodes directed towards the objects. OF activity did not change after 6 months. Testing aged pet dogs for spontaneous behaviour might help to better characterise cognitively affected individuals

Una propuesta de consenso sobre el concepto de exclusión: implicaciones metodológicas

En este texto se analiza la exclusión social desde los niveles institucional y político e individual-grupal y se profundiza en su origen estructural, su carácter multidimensional y su naturaleza procesual. En particular, se analiza la exclusión como fenómeno estructural en lo relativo a las transformaciones ocurridas en los últimos años en estructuras de integración social como el empleo, el Estado de Bienestar y las redes sociales, comunitarias y de parentesco. También se analizan diversas investigaciones nacionales e internacionales sobre la exclusión social que destacan por sus aportaciones metodológicas y se reflexiona en torno a las metodologías de análisis de la exclusión social. A este respecto, se plantean diversas sugerencias sobre los sistemas de información de los dispositivos de atención a población excluida, tanto públicos como de iniciativa social y se realiza una propuesta de indicadores multidimensional que abarca aspectos económicos, políticos y sociales

A crise social desenhada pelas crianças: imaginação e conhecimento social

A crise social e económica que tem atingido o mundo desde 2008, com efeitos especialmente sentidos nos países do Sul da Europa, causou impactos fortes e visíveis na infância, como o aumento das taxas efetivas e de risco de pobreza e a vulnerabilidade e a exposição a fatores de risco social e de perda consistente de direitos. A análise dessas incidências tem vindo a ser trabalhada num conjunto de relatórios nacionais e internacionais, de ONG’s e estudos académicos. No entanto, poucos estudos têm dedicado atenção ao modo como a interpretação das representações das crianças sobre a crise é feita e sobre as expressões específicas que estas assumem na sua vida quotidiana. As crianças são capazes de observar os modos como a crise impacta o seu próprio grupo geracional, bem como os adultos que mais lhe são próximos. Da mesma forma, promovem interpretações económicas sobre os fenómenos, sejam elas mais “ingénuas” ou mais complexas. Este artigo incide sobre as representações das crianças sobre a crise social e económica em Portugal. São especialmente analisadas narrativas gráficas produzidas por crianças oriundas de classes trabalhadoras, com idades compreendidas entre os 6 e os 10 anos de idade. Por meio dessas narrativas, as crianças constroem formas visuais a partir da sua imaginação sobre a sua condição. Assim, a imaginação das crianças é um modo de acesso ao conhecimento na sociedade onde se inserem e aos seus modos próprios de compreensão de realidades complexas.The social and economic crisis that has hit the world since 2008, with effects strongly felt in the countries of Southern Europe, has had fierce and visible impacts in childhood with the increase of the effective rates, the risk of poverty and vulnerability, and the exposure to factors of social risk and consistent loss of rights. The analysis of these incidents has been worked on in a series of national and international reports from NGOs and academic studies. However, few studies have devoted attention to the way in which the interpretation of the representations of children about the crisis is made and the specific expressions that they assume in their daily lives. Children are able to observe the ways in which the crisis affects their own generational group as well as the adults closest to them. In the same way, they promote economic interpretations of phenomena, whether “naïve” or more complex. This article focuses on the representations of children about the social and economic crisis in Portugal. Graphical narratives produced by children from working classes, aged between 6 and 10 years old, are given focus. From these narratives, children construct visual forms from their imagination about their social condition. Thus, the child’s imagination is a way of accessing knowledge in the society they belong to and their own way of understanding complex realities.CIEC - Centro de Investigação em Estudos da Criança, IE, UMinho (UI 317 da FCT), Portugalinfo:eu-repo/semantics/publishedVersio

Desarrollo de Soluciones para E-Learning: Diferentes Enfoques, un Objetivo Común

Abstract— As result of the discussions maintained at the Panel Session on “Software Development for E-Learning” of the 3rd Workshop on Software Engineering for E-Learning (ISELEAR’12), several points of view emerged regarding the conception, development and maintenance of E-Learning solutions. This paper summarizes and confronts these points of view: automated approaches, combination of different methodologies, emphasis on human and social aspects, domain- specific development approaches, model-driven / language- driven development and system integration approaches, and grammar-oriented development. While these points of view support different approaches to the engineering process, all of them share a common goal: to facilitate the development of complex E-Learning applications and solutions by multidisciplinary teams of software developers, instructors, domain experts, students and final users

The global Alzheimer's Association round robin study on plasma amyloid β methods

Introduction: Blood-based assays to measure brain amyloid beta (Aβ) deposition are an attractive alternative to the cerebrospinal fluid (CSF)-based assays currently used in clinical settings. In this study, we examined different blood-based assays to measure Aβ and how they compare among centers and assays. Methods: Aliquots from 81 plasma samples were distributed to 10 participating centers. Seven immunological assays and four mass-spectrometric methods were used to measure plasma Aβ concentrations. Results: Correlations were weak for Aβ42 while Aβ40 correlations were stronger. The ratio Aβ42/Aβ40 did not improve the correlations and showed weak correlations. Discussion: The poor correlations for Aβ42 in plasma might have several potential explanations, such as the high levels of plasma proteins (compared to CSF), sensitivity to pre-analytical sample handling and specificity, and cross-reactivity of different antibodies. Different methods might also measure different pools of plasma Aβ42. We, however, hypothesize that greater correlations might be seen in future studies because many of the methods have been refined during completion of this study

Disability, support and long-term social care of an elderly Spanish population, 2008-2009: an epidemiologic analysis

BACKGROUND: Though poorly known, relationships between disability, need of help (dependency) and use of social services are crucial aspects of public health. The objective of this study was to describe the links between disability, officially assessed dependency, and social service use by an industrial population, and identify areas of inequity. METHODS: We took advantage of a door-to-door survey conducted in the Cinco Villas district, Spain, in 2008–2009, which provided data on disability, morbidity, and service use among 1216 residents aged ≥50 years, and officially assessed dependency under the 2006 Dependency Act (OAD). Using logistic regression, we combined data collected at homes/residences on 625 disability screened-positive participants, and administrative information on degree of OAD and benefits at date of visit. RESULTS: Based on 163 disabled persons, the prevalence of residential/community-care users was 13.4% overall, with 6.0% being market-provided, 2.5% supported by the 2006 Act, and 4.9% supported by other public funds. Of 111 OAD applicants, 30 had been assigned an OAD degree; in 29 cases this was the highest OAD degree, with 12 receiving direct support for residential care and 17 receiving home care. Compared to unassessed dependency, the highest OAD degree was linked to residential care (OR and 95% CI) 12.13 (3.86–38.16), declared non-professional care 10.99 (1.28–94.53), and publicly-funded, non-professional care 26.30 (3.36–205.88). In contrast, 43 persons, 58% of the severely/extremely disabled, community-dwelling sample population, 81% of whom were homebound, including 10 persons with OAD but no implemented service plan, made no use of any service, and of these, 40% lacked a non-professional carer. CONCLUSIONS: Formal service use in the Cinco Villas district attained ratios observed for established welfare systems but the publicly-funded proportion was lower. The 2006 Act had a modest, albeit significant, impact on support for non-professional carers and residential care, coexisting with a high prevalence of non-use of social services by severely disabled persons

Molecular genetic mechanisms of allelic specific regulation of murine Comt expression

A functional allele of the mouse catechol-O-methyltransferase (Comt) gene is defined by the insertion of a B2 short interspersed repeat element in its 3′-untranslated region (UTR). This allele has been associated with a number of phenotypes, such as pain and anxiety. In comparison with mice carrying the ancestral allele (Comt+), ComtB2i mice show higher Comt mRNA and enzymatic activity levels. Here, we investigated the molecular genetic mechanisms underlying this allelic specific regulation of Comt expression. Insertion of the B2 element introduces an early polyadenylation signal generating a shorter Comt transcript, in addition to the longer ancestral mRNA. Comparative analysis and in silico prediction of Comt mRNA potential targets within the transcript 3′ to the B2 element was performed and allowed choosing microRNA (miRNA) candidates for experimental screening: mmu-miR-3470a, mmu-miR-3470b, and mmu-miR-667. Cell transfection with each miRNA downregulated the expression of the ancestral transcript and COMT enzymatic activity. Our in vivo experiments showed that mmu-miR-667-3p is strongly correlated with decreasing amounts of Comt mRNA in the brain, and lentiviral injections of mmu-miR-3470a, mmu-miR-3470b, and mmu-miR-667 increase hypersensitivity in the mouse formalin model, consistent with reduced COMT activity. In summary, our data demonstrate that the Comt+ transcript contains regulatory miRNA signals in its 3′-untranslated region leading to mRNA degradation; these signals, however, are absent in the shorter transcript, resulting in higher mRNA expression and activity levels
