Music, wellbeing and engagement in early childhood: reflections from a pilot study focused on sound as artistic matter

Recent research in Music Education and Music Psychology has established important connections between music and children's wellbeing (Hallam, 2015, 2016; Hallam, Creech & Varvarigou, 2017; Smith, 2021). Consequently, several researchers have highlighted the need to implement more inclusive and democratic practices in formal and non-formal educational contexts, involving all children in participatory and meaningful musical experiences (Benedict et al. 2015; Hess, 2017; Wright, 2015). Following this demand, some scholars have criticized hegemonic Eurocentric approaches to music education, suggesting instead a departure from sound and sounding phenomena as larger categories that might incorporate children's diverse trajectories and life experiences, and invite all children to participate in truly engaged ways (Recharte, 2019; Thumlert & Nolan, 2019; Thumlert, Harley & Nolan, 2020). This paper reports preliminary findings of a pilot study that is being developed in a Portuguese non-profit association located in the central area of Portugal. This association aims to develop inclusive and democratic projects with children from 0 to 6 years old - that are not integrated in other social facilities such as nursery schools or Kindergartens - and their respective families. One of the main goals of this association is to raise the awareness of children's rights among community members and beyond, namely the right children have to free play since their birth. The pilot study covers 12 music education sessions named "Sound Hunters", dedicated to the development of an approach to music education with an intense playful component, departing from sound as artistic matter and involving competences related to deep listening, sound exploration and experimentation. All the activities were planned and implemented in an action-research project, using a series of new devices and tools specially created and adapted to children, that could be easily explored and manipulated by them autonomously. The participants included 15 children with ages ranging from 18 months to 5 years old, the association team and the authors as facilitators. This study applied the Leuven Scales (Laevers, 2005) to assess the children's levels of involvement and wellbeing, using data from participant observation, field notes, and video and audio recordings. Results from this assessment were then triangulated with data from informal conversations and interviews with children and the association team. It was found that, during the periods of observation, children evidenced high and very high levels of wellbeing and involvement, especially manifested in their receptivity to the activities proposed during the sessions, self-confidence and self-assurance, and on their levels of attention, interest, and creativity. These findings were then corroborated by what children mentioned during the interviews and informal conversations about their personal experiences during the sessions. In this paper we argue that these findings emerge as a consequence of the opportunities offered to children to make connections with sound phenomena deeply related with their daily lives and interact collaboratively with sounds through participatory processes genuinely opened to creativity and experimentation. Finally, we discuss how this perspective might promote more meaningful and inclusive educational practices, discussing the implications and challenges posed to music education in early childhood.publishe

Sound hunters: an invitation for a soundwalk on the local community

This worshop is based on the pilot project "Sound Hunters: Towards a Pedagogy based on Listening and Sound Exploration in Early Childhood", that the authors are implementing in a non-formal educational context in Portugal. This workshop emerges from "a double call" that has recently been made in the field of music education. A call that asks, on the one side, for a new perspective on the concept of "music" - that might include the entire soundscape that surrounds us (Landy, 2007; Solomos, 2020) - and, on the other side, for more inclusive and democratic practices in music education, that might create learning opportunities for all children (Benedict et al. 2015; Hess, 2017; Wright, 2015). In this workshop we aim to give a contribution to this double call by inviting participants for a soundwalk, that will be used as a means to (re)connect participants with the local soundscape through active and attentive listening (Clarke, 2005; Deans, Brown & Dilkes, 2005), and to introduce the idea of Sound Ecology (Schaffer, 1977; Truax, 2019; Etmektsoglou, 2019). Departing from a previously prepared roadmap, and divided into 4 small groups, participants will take a route through the conference venue, while focusing on listening to the sounds that surround them, a process that has been defined as a Soundwalk (Westerkamp, 2011; Behrent, 2018 ). This route will have several stopping points where participants will find diverse listening tools such as "prepared headphones", devices for recording and manipulate sounds, "listening acoustic cones", among others. The purpose of these apparatus is to invite and facilitate different interactions with sounds, so that participants can engage in meaningful and active listening experiences related with the surrounding soundscape. In the end, participants will share their experiences with the group in an informal conversation, where they will be invited to talk about important moments and key events experienced during the soundwalk. This conversation will be guided by the authors and aims to better understand how the soundwalk affected participants' feelings and ideas about their sonic worlds, their relationships with sounds, the local landscape and local community, and their ideas about music. At the end of the workshop it is expected that the participants might be able to: (i) Identify sound as part of each person's sensory experience; (ii) Identify, describe and compare different sounds and soundscapes; (iii) Explore, in a creative way, different sound sources and tools related to the perception and appropriation of sound; (iv) Explore the idea of Sound Ecology, relating sounds with the diverse environments in which they usually participate; (v) reflect and rethink their ideas and conceptions of "music" and "musical". Target audience: Children (2-5 years old), their families, educators, musicians, researchers and general public.publishe

A intencionalidade educativa do educador de infância num contexto de pedagogia-em-participação: avaliação e qualidade da intervenção educativa na educação de infância

Doutoramento em Didáctica e Formação - AvaliaçãoA presente investigação enquadra-se na avaliação e qualidade da intervenção educativa na Educação de Infância, assumindo neste estudo um relevante enfoque as questões da intencionalidade educativa. Tendo como suporte um estudo de caso qualitativo, realizado num contexto de Jardim de Infância que desenvolve a Pedagogia-em-Participação enquanto perspetiva educacional sustentadora da intervenção educativa, procurou-se compreender quais eram as intencionalidades que os educadores de infância detinham e de que forma é que estas se manifestavam, a três níveis: i) o que o profissional pensava relativamente à sua intervenção educativa; ii) como é que organizava a sua intervenção e como intervinha no contexto onde estava inserido; iii) o que procurava observar, registar e documentar, enquanto forma de dar visibilidade às aprendizagens das crianças e às suas próprias intencionalidades. Enquanto forma de atribuição de uma sustentação teórica a esta investigação e enquanto estratégia de definição dos procedimentos do traçado investigativo, procedeu-se ao estudo do pensamento de alguns pedagogos e à sua relação com a questão da intencionalidade educativa. Realizou-se, equitativamente, um aprofundamento de compreensões em torno de modelos pedagógicos de cariz participativo. Procedeu-se à análise e compreensão teórica e empírica do objeto de estudo, tendo subjacente dimensões da pedagogia da infância referenciadas no quadro teórico desta investigação, a saber: tempo pedagógico, espaços e materiais pedagógicos, interações, atividades e projetos, observação, planificação e registo, avaliação e documentação pedagógica. A fase de investigação empírica desenvolveu-se entre setembro de 2010 e julho de 2012 e considerou quatro subfases: subfase 0 – Negociação do estudo e acesso ao campo; subfase I – Familiarização com o contexto; subfase II – Observação sistemática e registo de notas de campo; subfase III – Análise dos portefólios de aprendizagem das crianças; subfase IV – Inquérito por entrevista aos educadores de infância.Os resultados do estudo apontam para a expressão da intencionalidade a diversos níveis. A intencionalidade evidenciou-se tanto nas ações e pensamentos dos intervenientes no processo educativo, como no ambiente educativo e na documentação pedagógica. Tanto as crianças como os educadores foram protagonistas da ação e participaram na definição, concretização e avaliação de intencionalidades. Apesar de emergirem de sujeitos diversos e em circunstâncias diferentes do quotidiano educativo, as intencionalidades dos sujeitos harmonizaram-se com os propósitos pedagógicos delineados pela Pedagogia-em-Participação para os tempos da rotina educativa, que tanto as crianças como os educadores conheciam. Os resultados do estudo clarificam que, para se identificar e interpretar a intencionalidade educativa do educador de infância, há necessidade de se atentar para a organização do ambiente educativo (espaços e materiais), para a sua dinâmica (tempo pedagógico) e para os propósitos subjacentes a esta mesma dinâmica. Para além disso, o ambiente educativo materializa e facilita a emergência das intencionalidades tanto do educador como das crianças. Os resultados do estudo revelam que a documentação assume-se um espelho de evidências dos propósitos dos sujeitos: espelho da forma como pensam, observam, sentem, valorizam e representam a realidade experienciada. Uma visão integradora e holística em torno dos resultados permite, por fim, evidenciar a necessidade de se proceder a mais estudos no âmbito desta temática, nomeadamente, no domínio das pedagogias participativas.This investigation focuses on the assessment and quality of educational intervention in Childhood Education. This study assumes a relevant approach to the issues of educational intentionality in the scope of Pedagogy-in- Participation. Having as support a case study of ethnographic nature, developed in the context of a Pedagogy-in-Participation kindergarten, as an educational perspective of intervention for early childhood educators, we sought to explore and understand what were the intentions held by early childhood educators and their manifestations, at three levels: i) what the professional thought regarding his/her educational intervention, ii) how he organized his intervention and how he intervened in the context where he was inserted iii) what he sought to observe, record and document as a way to give visibility to children's learning and their own intentions. We analysed the theories of world-renowned pedagogues with special emphasis on the correlations of their educational perspectives with educational intentionality, to provide theoretical support to this research and to better define the proceedings of the investigation. It was also essential for the study to gain insights in models and in participatory pedagogical perspectives, Analysis and understanding of the theoretical and empirical object of study were performed, underlying the childhood pedagogy dimensions referenced in the theoretical framework of this research, namely: pedagogical time, pedagogical space and materials, interactions, activities and projects, observation, planning and evaluation, groups and pedagogical documentation. The phase of empirical research was developed between September 2010 and July 2012 and considered four subphases: subphase 0 – Study negotiation and access to the research field; subphase I - Familiarization with the context; subphase II - Systematic observation and recording of field notes; subphase III - Analysis of children’s learning portfolios, subphase IV - Interview survey to the educators.The results of this study point to the expression of intentionality at different levels, owing to the fact that intentionality was shown in an implicit and explicit way, either in thoughts and actions of those involved in the educational process (educators and children), or in the educational environment and in pedagogical documentation. In the context of Pedagogy-in-Participation both children and educators were the central character in each action and participated in the definition, concretion and evaluation of intentions. Although the intentions emerged from different individuals and situations of the everyday educational routine, they were in harmony with the pedagogical purposes outlined by the Pedagogy-in- Participation theory, in what concerns the routine educational times known by that both children and educators. The study also clarified that in order to identify and interpret the educational intentionality of the early childhood educator, one needs to know the organization of the educational environment (spaces and materials), its dynamics (pedagogical time) and the objectives underlying that dynamics, since the educational environment materializes and facilitates the emergence and development of the intentions of both the educator and the children. The pedagogical documentation was interpreted as a mirror of each individual’s purposes, of how they thought, saw, felt, valued and represented the reality experienced by themselves and by others. A holistic and integrated insight of the results emerging from this research allowed evidencing the need for more studies in the particular research area of participatory pedagogies

Adenoid bacterial colonization in a paediatric population

Adenoids play a key role in both respiratory and ear infection in children. It has also been shown that adenoidectomy improves these symptoms in this population. The main goal of the present study was to evaluate adenoid bacterial colonization and document a possible relation with infectious respiratory disease. A prospective observational study was designed to evaluate the proposed hypothesis in a paediatric population submitted to adenoidectomy by either infectious or non-infectious indications and compare these two cohorts. A total of 62 patients with ages ranging from 1 to 12 years old were enrolled in the study. Adenoid surface, adenoid core and middle meatus microbiota were compared. A close association between adenoid colonization and nasal infection was found, supporting that adenoids may function as bacterial reservoir for upper airway infection. The obtained results also contribute to explain the success of adenoidectomy in patients with infectious indications.Nacional de Saúde Dr. Ricardo Jorge (Grant 2015DDI1143)info:eu-repo/semantics/publishedVersio

Highlighting the biological potential of the brown seaweed Fucus spiralis for skin applications

Skin aging is a biological process influenced by intrinsic and extrinsic factors. The last ones, mainly exposure to UV radiation, increases reactive oxygen species (ROS) production leading to a loss of extracellular matrix, also enhanced by enzymatic degradation of matrix supporting molecules. Thus, and with the growing demand for eco-friendly skin products, natural compounds extracted from brown seaweeds revealed to be good candidates due to their broad range of bioactivities, especially as antioxidants. The aim of this study was to assess the dermo-cosmetic potential of di erent fractions obtained from the brown seaweed Fucus spiralis. For this purpose, in vitro antioxidant (Total Phenolic Content (TPC), 1,1-Diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, Ferric Reducing Antioxidant Power (FRAP), Oxygen Radical Absorbance Capacity (ORAC)), anti-enzymatic (collagenase, elastase and hyaluronidase), antimicrobial, anti-inflammatory (NO production) and photoprotective (ROS production) capacities were evaluated. Although nearly all fractions evidenced antioxidant e ects, fraction F10 demonstrated the highest antioxidant ability (EC50 of 38.5 g/mL, DPPH assay), and exhibited a strong e ect as an inhibitor of collagenase (0.037 g/mL) and elastase (3.0 g/mL). Moreover, this fraction was also the most potent on reducing ROS production promoted by H2O2 (IC50 of 41.3 g/mL) and by UVB (IC50 of 31.3 g/mL). These bioactivities can be attributed to its high content of phlorotannins, as evaluated by LC-MS analysis, reinforcing the potential of F. spiralis for further dermatological applications.info:eu-repo/semantics/publishedVersio

The protective effect of Staphylococcus epidermidis biofilm matrix against phage predation

Staphylococcus epidermidis is a major causative agent of nosocomial infections, mainly associated with the use of indwelling devices, on which this bacterium forms structures known as biofilms. Due to biofilms’ high tolerance to antibiotics, virulent bacteriophages were previously tested as novel therapeutic agents. However, several staphylococcal bacteriophages were shown to be inefficient against biofilms. In this study, the previously characterized S. epidermidis-specific Sepunavirus phiIBB-SEP1 (SEP1), which has a broad spectrum and high activity against planktonic cells, was evaluated concerning its efficacy against S. epidermidis biofilms. The in vitro biofilm killing assays demonstrated a reduced activity of the phage. To understand the underlying factors impairing SEP1 inefficacy against biofilms, this phage was tested against distinct planktonic and biofilm-derived bacterial populations. Interestingly, SEP1 was able to lyse planktonic cells in different physiological states, suggesting that the inefficacy for biofilm control resulted from the biofilm 3D structure and the protective effect of the matrix. To assess the impact of the biofilm architecture on phage predation, SEP1 was tested in disrupted biofilms resulting in a 2 orders-of-magnitude reduction in the number of viable cells after 6 h of infection. The interaction between SEP1 and the biofilm matrix was further assessed by the addition of matrix to phage particles. Results showed that the matrix did not inactivate phages nor affected phage adsorption. Moreover, confocal laser scanning microscopy data demonstrated that phage infected cells were less predominant in the biofilm regions where the matrix was more abundant. Our results provide compelling evidence indicating that the biofilm matrix can work as a barrier, allowing the bacteria to be hindered from phage infection.This study was supported by the Portuguese Foundation for Science and Technology (FCT)under the scope of the strategic funding of UIDB/04469/2020 unit, and Project PTDC/SAU-PUB/29182/2017 [POCI-01-0145-FEDER-029182].

Contra a maré cremos, crianças, que basta edificar mais cubos e muralhas de areia

This work is not a scientific paper and therefore does not follow the typical structure. This text is a collection of the opinions of several researchers that share a common interest in coastal areas. They were asked to reflect – based on their personal and professional experience – about present coastal management, using as a start the phrase of the plastic artist Carlos Augusto Ribeiro – Like children we believe that stopping the tide is only a matter of building more sand walls. Several themes are addressed: traditional populations and knowledge, maritime engineering works, conflict management, ecosystems destruction and unsustainability, new models for coastal management and participative citizenship.info:eu-repo/semantics/publishedVersio

Grey platelet disease

Grey Platelet disease is a rare disease characterized by morphologic changes in platelets alpha-granules. These proteins are essential for the homeostasis, so the patients with this blood defect present hemorrhagic disturbs. The blood discrasia is usually mild, however some patients could present more serious manifestations, usually after a severe trauma. The authors present the following clinical report about a patient that was admitted in a Medical Department with a severe bleeding and mild thrombocytopenia. The patient was submitted to an extensive study to determine the etiology (autoimmunity serology, myelogram, coagulation study) that were all normal. The diagnosis of Idiopathic Thrombocytopenic Purpura was considered. Six months after a worsening of the hemorrhagic discrasia and thrombocytopenia the patient was assisted. Corticotherapy was initiated without improvement. The morphology of the platelets was revised and the blood smear with Wright coloration revealed the presence of large, pale and grey platelets. The electronic microscopy confirmed the diagnosis of Grey Platelet disease. The family of the patient was studied and we found that two direct relatives were affected with the same disease. In these family these syndrome probably has autossomic dominant inherence.publishersversionpublishe

Different locations but common associations in subcortical hypodensities of presumed vascular origin: cross-sectional study on clinical and neurosonologic correlates

BACKGROUND: Subcortical hypodensities of presumed vascular etiology (SHPVO) are a clinical, radiological and neuropathological syndrome with a still largely unexplained pathophysiology. Parallel to the clinical heterogeneity, there is also recognised cerebral topographical diversity with undetermined etiological implications. Our aim is to assess clinical and neurosonological predictors of SHPVO according to their location. METHODS: Cross sectional analysis of consecutive patients that underwent neurosonologic evaluation and head CT within one month, during a one year period. We excluded patients with absent temporal sonographic window, any pathology with a possible confounding effect on cerebral arterial pulsatility, atrial fibrillation and other etiologies of white matter diseases. The mean pulsatility index (PI) of both middle cerebral arteries was measured in the middle third of the M1 segment; intima media thickness was evaluated in the far wall of both common carotid arteries. SHPVO were rated by analysis of head CT in deep white matter (DWMH), periventricular white matter (PVWMH) and basal ganglia (BGH). We conducted a multivariate ordinal logistic regression model including all clinical, demographic and ultrasonographic characteristics to determine independent associations with SHPVO. RESULTS: We included 439 patients, mean age 63.47 (SD: 14.94) years, 294 (67.0%) male. The independent predictors of SHPVO were age (OR = 1.067, 95% CI: 1.047-1.088, p < 0.001 for DWMH; OR = 1.068, 95% CI: 1.049-1.088, p < 0.001 for PVWMH; OR = 1.05, 95% CI: 1.03-1.071, p < 0.001 for BGH), hypertension (OR = 1.909, 95% CI: 1.222-2.981, p = 0.004 for DWMH; OR = 1.907, 95% CI: 1.238-2.938, p = 0.003 for PVWMH; OR = 1.775, 95% CI: 1.109-2.843, p = 0.017 for BGH) and PI (OR = 17.994, 95% CI: 6.875-47.1, p < 0.001 for DWMH; OR = 5.739, 95%CI: 2.288-14.397, p < 0.001 for PVWMH; OR = 11.844, 95% CI: 4.486-31.268, p < 0.001 for BGH) for all locations of SHPVO. CONCLUSIONS: Age, hypertension and intracranial pulsatility are the main independent predictors of SHPVO across different topographic involvement and irrespective of extracranial atherosclerotic involvement
