    Public speaking is a widely requested professional skill, and at the same time an activity that causes one of the most common adult phobias (Miller and Stone, 2009). It is also known that the study of stress under laboratory conditions, as it is most commonly done, may provide only limited ecological validity (Wilhelm and Grossman, 2010). Previously, we introduced an inter-disciplinary methodology to enable collecting a large amount of recordings under consistent conditions (Aguiar et al., 2013). This paper introduces the VOCE corpus of speech annotated with stress indicators under naturalistic public speaking (PS) settings. The novelty of this corpus is that the recordings are carried out in objectively stressful PS situations, as recommended in (Zanstra and Johnston, 2011). The current database contains a total of 38 recordings, 13 of which contain full psychological and physiologic annotation. We show that the collected recordings validate the assumptions of the methodology, namely that participants experience stress during the PS events. We describe the various metrics that can be used for physiologic and psychological annotation, and we characterise the sample collected so far, providing evidence that demographics do not affect the relevant psychological or physiologic annotation. The collection activities are on-going, and we expect to increase the number of complete recordings in the corpus to 30 by June 2014

    Computer simulation of simultaneous evolution of individual texture components During recrystallization of an IF steel

    Computer simulation of simultaneous evolution of individual texture components during recrystallization of an IF steel is carried out. A new methodology has been developed that takes as its starting point experimental data of each texture component evolving during recrystallization. In particular, Magnusson et al. data on IF steel was analyzed in a previous work with the help of the exact analytical tools developed by Rios and Villa for simultaneous transformations. From this analysis parameters such as number of nuclei of each texture component per unit of volume could be obtained and were employed as input for the present computer simulation. From this input 3-d microstructures could then be generated. The methodology proposed here combines experimental data, exact analytical methods and computer simulation and may be employed to extract the maximum information from the experimental data

    BACKGROUND: Latin America Treatment and Innovation Network in Mental Health (LATIN-MH) is a research hub located in Brazil and Peru that conducts a research project to help reduce the treatment gap in mental health in Latin America (LA). Besides its research core, LATIN-MH has a Capacity Building (CB) component that aims to help young researchers receive the specific training to contribute to the growing scientific production in mental health in LA. METHODS: LATIN-MH proposal in CB includes a series of actions to prepare professionals in the research area. The main proposals are described here, which include online study groups, promotion of scientific meetings, hands-on training in different levels and sharing of information. RESULTS: LATIN-MH CB activities are at its initial stages but the proposed activities were well evaluated by the participants. The first participating fellows who finished their fellowships are contributing elsewhere in the mental treatment and human resources formation area. CONCLUSION: The repercussion of LATIN-MH actions in CB and its evaluation, particularly on the formation of human resources and dissemination of information, show that the hub is contributing to the critic formation of young researchers and the circulation of important information

    p518, a small floR plasmid from a South American isolate of Actinobacillus pleuropneumoniae

    A small (3.9 kb) plasmid (p518), conferring resistance to florfenicol (MIC >8 μg/mL) and chloramphenicol (MIC >8 μg/mL) was isolated from an Actinobacillus pleuropneumoniae clinical isolate from Southeastern Brazil. To date, this is the smallest florfenicol resistance plasmid isolated from a member of the Pasteurellaceae. The complete nucleotide of this plasmid revealed a unique gene arrangement compared to previously reported florfenicol resistance plasmids found in other members of the Pasteurellaceae. In addition to the floR gene and a lysR gene, common to various florfenicol resistance plasmids, p518 also encodes strA and a partial strB sequence. An origin of replication (oriV) similar to that in the broad host range plasmid, pLS88, was identified in p518, and transformation into Escherichia coli MFDpir confirmed the ability to replicate in other species. Mobilisation genes appear to have been lost, with only a partial mobC sequence remaining, and attempts to transfer p518 from a conjugal donor strain (E. coli MFDpir) were not successful, suggesting this plasmid is not mobilisable. Similarly, attempts to transfer p518 into a competent A. pleuropneumoniae strain, MIDG2331, by natural transformation were also not successful. These results suggest that p518 may be only transferred by vertical descent

    The distribution of neighbourhood walkability indicators in an African city: Praia, Cabo Verde

    This paper analyses disparities in walking conditions in neighbourhoods with different incomes and urbanization levels in Praia, the capital of Cabo Verde islands. Walkability is measured considering factors relevant to a semi-arid, post-colonial, fast growing, middle-income African city. The estimated indicators measure the availability of destinations accessible on foot and the quality of the walking experience. The study found that high income neighbourhoods have the lowest overall provision of pedestrian space and protection from traffic (in more urbanized areas) and the lowest walking accessibility to people, shops, and leisure areas (in less urbanized areas). Low income neighbourhoods have the highest environmental risks (in more urbanized areas) and the highest slopes, lowest provision of formal pedestrian space, and lowest accessibility to jobs, facilities, and bus stops (in less urbanized areas). The results provide insights into the type of public policies needed to improve walkability in the different parts of the city

    Depression Among Portuguese Pregnant Women During Covid-19 Lockdown: A Cross Sectional Study

    Get PDF
    Introduction: Coronavirus disease 2019 was declared as a pandemic on March 2020. Research on its psychological effects is still lacking. Perinatal depression is a medical complication of pregnancy, especially in situations of stress. In this study, we aimed to investigate the presence of symptoms of depression in pregnant women during the lockdown period in Portugal. Methods: This study consisted in a cross-sectional study among Portuguese pregnant women, who completed an online self-report questionnaire between 25th April and 30th April 2020. An anonymous online questionnaire was developed to assess depression and concerns related to COVID-19. This study was approved by the IRB of Hospital Dona Estefânia and performed in accordance with the ethical standards laid down in the 1964 Declaration of Helsinki. Eligibility criteria included pregnant women, ≥ 18 years and living in Portugal. The primary outcome was to evaluate the presence of depressive symptoms and its association to socio-demographic characteristics and to concerns related to COVID-19. Results: A total of 1698 pregnant women were enrolled. The mean age was 31.9 years. 82.4% felt a negative impact of the pandemic in the surveillance of pregnancy and 43% felt insufficient support. 26.3% showed "possible depression" according to the EPDS. A regression analysis revealed the possibility of depression increased as the concerns about COVID increased and was lower for women with support. The possibility of depression was higher for women with psychiatric medical history. Conclusion: This study demonstrated a significant increase in clinically significant depressive symptoms in pregnant women during the lockdown. It also revealed some of the socio-demographic characteristics of women at risk for depression. If left untreated, depression tends to persist, affecting the woman and also the child. Our findings suggest that COVID-19 represents a serious challenge for this population and reinforce the urgent need for early detection and intervention on mental health issues during pregnancy, especially during the pandemic.info:eu-repo/semantics/publishedVersio

    A democracia como um terreno em disputa: as tensões do liberalismo com a ampliação dos direitos políticos

    Get PDF
    O conceito de democracia foi sempre um terreno de disputa. Nesse sentido, a sua significação assume tons diferentes conforme o seu contexto histórico e geopolítico. Apesar disso, naturalizou-se uma relação indissolúvel entre democracia e liberalismo, que não corresponde à história do pensamento político liberal, tampouco o regime político instaurado pelas revoluções burguesas. Para desvelar tal questão, este estudo objetiva analisar a contradição entre o liberalismo (em particular, de Benjamin Constant e Alexy de Tocqueville) e a ampliação dos direitos políticos a partir da adoção do sufrágio universal
