Portuguese Children's Sleep Habits Questionnaire - validation and cross-cultural comparison

Objective: to validate the Portuguese version of the Children's Sleep Habits Questionnaire (CSHQ-PT) and compare it to the versions from other countries. Methods: the questionnaire was previously adapted to the Portuguese language according to international guidelines. 500 questionnaires were delivered to the parents of a Portuguese community sample of children aged 2 to 10 years old. 370 (74\%) valid questionnaires were obtained, 55 children met exclusion criteria and 315 entered in the validation study. Results: the CSHQ-PT internal consistency (Cronbach's alpha) was 0.78 for the total scale and ranged from 0.44 to 0.74 for subscales. The test-retest reliability for subscales (Pearson's correlations, n=58) ranged from 0.59 to 0.85. Our data did not adjust to the original 8 domains structure in Confirmatory Factor Analysis but the Exploratory Factor Analysis extracted 5 factors that have correspondence to CSHQ subscales. Conclusion: the CSHQ-PT evidenced psychometric properties that are comparable to the versions from other countries and adequate for the screening of sleep disturbances in children from 2 to 10 years old.

A poluição do Rio Araguaia como questão socioambiental no ensino de ciências: Objetivações para a formação soiopolítica

This research analyzes how the application of a Didactic Sequence, guided by the Science-Technology-Society-Environment (STSE) assumptions, can contribute to the engagement of students in environmental sociopolitical actions. Therefore, the guiding question of this research is: how can the application of a Didactic Sequence, guided by the assumptions of CTSA Education, contribute to the engagement of students in socio-political-environmental actions? In this way, we present an analysis of the didactic-pedagogical proposal in the face of the potential of teaching strategies that address controversial case studies and guiding questions for the achievement of conceptual, procedural and attitudinal learning objectives, explicitly considering ethical questions, positions and learners' decision-making. The theme used for the elaboration of the case is the "Pollution of the Araguaia River", understood as a socio-environmental issue, based on problematized situations, contextualized and related to scientific content. The Didactic Sequence aimed to explore conceptual aspects of STSE relations in the areas of ethical, moral and socio-environmental justice development, in order to contribute to the sociopolitical formation of the students involved. The research methodology is of a qualitative nature, in the form of participatory research carried out in a 9th grade class of Elementary School, applied from august to september 2021. As a reference for analysis, we used categorical analysis for the elaboration of classes on the levels of engagement of students in the face of socio-environmental problems. We took as previous categories of analysis of engagement levels: i) awareness; ii) understanding of the problem and; iii) environmental socio-political training. The research indicated that the opportunity to address proposed resolutions for real situations through discussions of economic, social, political, ethical and moral aspects related to socio-environmental problems contribute to the engagement of students in the didactic-pedagogical activities proposed in Science teaching. We consider that the didactic-pedagogical proposals used in this research are propellers for future discussions about the potential of Socio-environmental Issues, mainly for the engagement of students in the training process in Science classes.Esta pesquisa analisa como a aplicação de uma Sequência Didática, orientada pelos pressupostos Ciência-Tecnologia-Sociedade-Ambiente (CTSA), pode contribuir para o engajamento de educandos em ações sociopolítico ambientais.

Desse modo, apresentamos uma análise sobre a proposta didático-pedagógica frente às potencialidades das estratégias de ensino que abordam estudos de casos controversos e questões orientadoras para o alcance dos objetivos de aprendizagem conceitual, procedimental e atitudinal, considerando, explicitamente, questionamentos éticos, posicionamentos e tomadas de decisão dos educandos. O tema utilizado para a elaboração do caso é a “Poluição do rio Araguaia”, compreendida em uma questão socioambiental, tomando-se por base situações problematizadas, contextualizadas e relacionadas com os conteúdos científicos. A Sequência Didática visou explorar aspectos conceituais das relações CTSA nas vertentes sobre desenvolvimento ético, moral e de justiça socioambiental, a fim de contribuir para a formação sociopolítica dos estudantes envolvidos. A metodologia da pesquisa é de caráter qualitativo, sob a forma de pesquisa participante realizada em uma turma de 9º ano do Ensino Fundamental, aplicada de agosto a setembro de 2021. Como referencial de análise, utilizamos a análise categorial para a elaboração de classes sobre os níveis de engajamento dos educandos diante dos problemas socioambientais. Tomamos como categorias prévias de análise dos níveis de engajamento: i) sensibilização; ii) compreensão da problemática e; iii) formação sociopolítica ambiental. A pesquisa sinalizou que a oportunidade de abordar propostas de resolução para situações reais por meio de discussões de aspectos econômicos, sociais, políticos, éticos e morais relacionados com problemas socioambientais contribuem para o engajamento dos educandos nas atividades didático-pedagógicas propostas no ensino de Ciências. Consideramos que as propostas didático-pedagógicas usadas nesta pesquisa sejam propulsoras de futuras discussões acerca das potencialidades das Questões Socioambientais, principalmente, para o engajamento dos educandos no processo formativo nas aulas de Ciências

Expression of human Hemojuvelin (HJV) is tightly regulated by two upstream open reading frames in HJV mRNA that respond to iron overload in hepatic cells

Acessível em: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4372701/The gene encoding human hemojuvelin (HJV) is one of the genes that, when mutated, can cause juvenile hemochromatosis, an early-onset inherited disorder associated with iron overload. The 5' untranslated region of the human HJV mRNA has two upstream open reading frames (uORFs), with 28 and 19 codons formed by two upstream AUGs (uAUGs) sharing the same in-frame stop codon. Here we show that these uORFs decrease the translational efficiency of the downstream main ORF in HeLa and HepG2 cells. Indeed, ribosomal access to the main AUG is conditioned by the strong uAUG context, which results in the first uORF being translated most frequently. The reach of the main ORF is then achieved by ribosomes that resume scanning after uORF translation. Furthermore, the amino acid sequences of the uORF-encoded peptides also reinforce the translational repression of the main ORF. Interestingly, when iron levels increase, translational repression is relieved specifically in hepatic cells. The upregulation of protein levels occurs along with phosphorylation of the eukaryotic initiation factor 2α. Nevertheless, our results support a model in which the increasing recognition of the main AUG is mediated by a tissue-specific factor that promotes uORF bypass. These results support a tight HJV translational regulation involved in iron homeostasis

A concordância nominal de gênero na língua falada de estudantes caboverdianos da UNILAB-CE

Este trabalho objetiva discutir o uso da concordância nominal de gênero na língua falada por estudantes caboverdianos da Universidade de Integração Internacional da Lusofonia Afro-Brasileira (UNILAB), localizada em Redenção-CE, tomando por base o contato linguístico entre o crioulo caboverdiano, língua materna desses falantes, e o português. Ademais, são objetivos específicos: a) verificar que contextos favorecem ou restringem o uso dessa concordância; b) observar se o maior grau de escolaridade exerce influência para um uso linguístico mais próximo da norma europeia do português e c) analisar o tipo de regra linguística relacionada à concordância em análise, partindo da proposta de Labov (2003). Para tanto, foram selecionados doze informantes: seis do sexo feminino e seis do sexo masculino, sendo o corpus constituído de 166 sintagmas nominais. Durante a análise, foi utilizada a Teoria da Sociolinguística Variacionista (LABOV, 2008 [1972]) e foram aplicados aos dados os princípios linguísticos propostos por Lucchesi (2009). Os resultados mostram que: a) a regra de concordância de gênero é semicategórica, b) o princípio da saliência é atuante nos dados com a variante não-padrão, c) as estudantes tendem a usar mais a variante padrão e d) estudantes com menos tempo de permanência no Brasil usam mais a variante não-padrão

Stroke rehabilitation and research: consideration of the role of the cortico-reticulospinal system

A cerebrovascular accident, otherwise known as stroke, has the potential to damage multiple areas within the brain affecting descending motor control via a multitude of pathways resulting in a wide variety of movement problems. The cortico-reticulospinal system, one of the largest motor systems, is frequently affected, compromising its output, resulting in postural control deficits. The identification of clinically relevant instruments and scales to document and evaluate recovery in post-stroke patients is vital. However, the availability of such measures and scales which take into consideration the role of postural control as an integral component of functional movement performance are scarce. This paper will critically discuss the importance of integrating current neuroscience and motor control knowledge in order to better understand and describe the clinical presentation of persons post-stroke such that the effectiveness of stroke rehabilitation can be appropriately measured.info:eu-repo/semantics/publishedVersio

Land allocation and suitability analysis for the production of food, feed and energy crops in the period 2010 - 2050 EU Reference Scenario 2013 LUISA platform – Updated Configuration 2014

Since land is a finite resource, the competition for land among different uses has become a real problem. Competition for land takes place when different alternative uses (such as agriculture, forestry, energy or/and natural conservation) are competing for the same piece of land. When the competition for land is highly intense in a given territory, a specific land use/cover might cause the displacement of another one, leading to land-use conversion and, potential negative environmental, economic and social impacts. In the long term, this exacerbated competition might increase the pressure on the land and the impacts on the land capacity to support ecosystems and productive systems. Methodologies and tools to assess the potential impacts of bioenergy development in the EU on land uses and functions provide useful insight to shed light on the environmental impacts of energy policies. The territorial assessment carried out by the Land Use-based Sustainability Assessment (LUISA) modelling platform highlights where in Europe the current macro-economic trends and energy policy targets might pose a threat to our land resources in the mid to long term. This might happen, for instance, in regions where the demand for energy crops and the need for residential and industry/commerce/services functions, is forecasted to increase. Essential land uses, such as agriculture for food and feed production, could therefore be transferred to less suitable lands at a regional or local scale. The herein report explores in detail the land uses that are expected to be in direct competition for land (food, feed and energy) as a result of the EU bioenergy targets and considering the suitability characteristics of the land for these uses. The analysis is carried out per main crop group (cereals, maize, root crops, other arable crops and energy crops), as simulated by the LUISA modelling platform. The results presented highlight where and how the displacement of food and feed crops from highly suitable land to lower levels of suitability can be caused by different drivers, among which the expansion of built-up areas and dedicated energy crops. In summary, the majority of cereal, maize and root crops in Europe are allocated on land classified as highly suitable (according to local biophysical conditions, possible fertiliser input and current cropping patterns) between 2020 and 2050. However, the amount of land cultivated with food crops (cereal, maize and root crop production) is shown to experience a substantial decrease in the majority of the MSs, on average higher than 10% across the entire simulation period. On the opposite, energy crop production increases at fast pace, at times doubling the amount of allocated land from the year 2020, when they first appears in the modelling, to 2050. Due to the growth of residential and ICS (industry, commercial and services) sites, land highly suitable for the cultivation of food crops and non-food crops is increasingly being used for artificial uses. In general terms, growing crops on highly suitable land results in a cost reduction associated to inputs use, such as fertilizers, pesticides and water. However, as result of the competition, there is – in several areas in Europa - an increasing shift towards low quality land for growing food and feed crops, with environmental and economic impacts to be carefully evaluated.JRC.H.8-Sustainability Assessmen

Accessibility and territorial cohesion in a case of transport infrastructure improvements with changing population distributions

In the last decade or so many studies have looked into the impacts of infrastructure improvements on decreasing territorial disparities. In those studies population levels are usually assumed static, although future population levels likely change in response to changing accessibility levels as well as to other factors. This study uses future population distributions simulated by the LUMP land-use model to assess the impacts of large transport network investments on regional accessibility disparities. The results indicate that contrasting local urbanization patterns only modestly affect average national accessibility levels, but that those patterns have a considerable effect on regional inequality indicators. This underpins the importance of incorporating future population levels when assessing cohesion impacts of infrastructure investments.JRC.H.8-Sustainability Assessmen
