Sugestionabilidade interrogativa em crianças de 8 e 9 anos de idade

Para estudar a influência das variáveis idade, inteligência, memória, ansiedade geral e desejabilidade social na sugestionabilidade avaliaram-se crianças de 8 e 9 anos de idade com o Bonn Test of Statement Suggestibility (BTSS). Em 145 crianças averiguou-se o efeito das variáveis memória e inteligência não verbal e, numa subamostra de 74 crianças, para além das variáveis referidas, considerou-se também a inteligência verbal, ansiedade geral e desejabilidade social. As crianças de 8 anos são mais sugestionáveis do que as crianças mais velhas. No grupo dos 8 anos, aquelas com melhores desempenhos ao nível da inteligência não verbal (medida pelas Matrizes Progressivas Coloridas de Raven – MPCR), e na evocação da história do BTSS são menos sugestionáveis comparativamente às crianças com piores desempenhos nestas provas. De modo análogo, as crianças com 9 anos são tanto mais sugestionáveis quanto piores os desempenhos nas MPCR, evocação da história do BTSS e subtestes informação, vocabulário e aritmética da WISC–III. As crianças deste grupo etário que apresentam desejabilidade social elevada (avaliada pela RCMAS) são também mais sugestionáveis. Estes resultados são discutidos considerando a sua relevância para o âmbito forense.To study the influence of the variables age, intelligence, memory, general anxiety and social desirability in suggestibility, 8 and 9-year-old children were assessed using the Bonn Test of Statement Suggestibility (BTSS). The effect of the variables memory and non-verbal intelligence was studied in 145 children while, in a subsample of 74 children, the variables verbal intelligence, general anxiety and social desirability were also taken into account besides the ones previously referred to. Eight-year-old children are more suggestible than older children. In the eightyear- old group, those with better performances in nonverbal intelligence (measured by Raven’s Coloured Progressive Matrices – RCPM), and in the BTSS story recall are less suggestible compared to the children with worse performances in these tests. Similarly, the worse the performance achieved by nine-year-old children in RCPM, in the BTSS story recall and in the subtests of information, vocabulary and arithmetic of WISC-III are, the more suggestible they are. The children belonging to this age group who show high social desirability (evaluated by RCMAS) are also more suggestible. These results are discussed according to its relevance in the scope of the forensic field.info:eu-repo/semantics/publishedVersio

O papel do Conservatório de Música e Artes do Dão na formação profissional dos alunos através do ensino articulado de música: Retratos sociológicos de dez antigos alunos

Esta dissertação analisa as trajetórias individuais de carreira de um conjunto de dez jovens que frequentaram o ensino articulado de música, no Conservatório de Música e Artes do Dão, no segundo e terceiro ciclos, entre os anos 2007 e 2015. Através das entrevistas, de carácter biográfico, foi possível construir dez "retratos sociológicos", onde se analisaram os percursos dos antigos alunos, os tempos e os momentos da formação profissional, as desilusões e os sucessos, a importância da família, a influência dos professores e da escola do ensino articulado de música como um dos momentos cruciais de socialização destes jovens alunos. Nos seus discursos, os jovens destacam a qualidade de ensino do Conservatório de Música e Artes do Dão (CMAD), tendo este sido a sua "rampa de lançamento" para o "mundo das artes" da música. Aqueles que seguiram uma profissão artística mencionam a importância das atividades desenvolvidas no Conservatório para o enriquecimento dos seus interesses artísticos, despertando e desenvolvendo a sua criatividade. Por fim, os jovens que deixaram de lado a sua formação artística salientam a importância das ferramentas adquiridas durante a sua formação no ensino articulado de música, não só ao nível artístico, como também ao nível cognitivo e enquanto meio de socialização. Foi possível concluir que, independentemente da área profissional que estes jovens escolheram seguir, o ensino articulado de música teve um impacto positivo na sua trajetória de carreira académica e pessoal.This thesis analyzes the individual career paths of a group of ten young students who attended the articulated teaching of music at the Conservatório de Música e Artes do Dão (Conservatory of Music and Arts of Dão), between the years 2007 and 2015. Through the interviews, of a biographical nature, it was possible to construct ten "sociological portraits", where the career paths trajectories of the former students were analyzed, the times and moments of professional formation, the disappointments and successes, the importance of the family, the influence of the teachers and the school of the articulated teaching of music, as one of the crucial moments of socialization for these young students. In their speeches, the young students emphasized the quality of teaching at the Conservatório de Música e Artes do Dão (CMAD), which was their "beginning of the path" in the "art world" of music. Those who followed the artistic profession mention the importance of the activities developed at the Conservatory to enrich their artistic interests, awakening and developing their creativity. Finally, the young students who left their artistic training aside mention the importance of the tools acquired during their training in the articulated teaching of music, not only at the artistic level, but also at the cognitive and socialization level. It was possible to conclude that regardless of the professional domain they chose to pursue, the articulated teaching of music had a positive impact on their academic and personal trajectory of career

Although previous studies have shown the potential of the antimicrobial peptide nisin for PD control, there is no information regarding its influence in the development of antimicrobial resistance or horizontal gene transfer (HGT). Nisin’s mutant prevention concentration (MPC) and selection window (MSW) were determined for a collection of canine oral enterococci. Isolates recovered after the determination of the MPC values were characterized for their antimicrobial profile and its nisin minimum inhibitory and bactericidal concentrations. The potential of vanA HGT between Enterococcus faecium CCGU36804 and nine clinical canine staphylococci and enterococci was evaluated. Nisin MPC values ranged from 400 to more than 600 µg/mL. In comparison with the original enterococci collection, the isolates recovered after the determination of the nisin MPC showed increased resistance towards amoxicillin/clavulanate (5%), vancomycin (5%), enrofloxacin (10%), gentamicin (10%) and imipenem (15%). The HGT of vanA gene was not observed. This work showed that nisin selective pressure may induce changes in the bacteria’s antimicrobial resistance profile but does not influence horizontal transfer of vanA gene. To our knowledge, this is the first report of nisin’s MPC and MSW determination regarding canine enterococci.Authors would like to acknowledge the Foundation for Science and Technology (Eva Cunha PhD fellowship SFRH/BD/131384/2017) and to CIISA–Centro de Investigação Interdisciplinar em Sanidade Animal, Faculdade de Medicina Veterinária, Universidade de Lisboa, Project UIDB/00276/2020 (Funded by FCT), for financial support of this work.info:eu-repo/semantics/publishedVersio

Proteins as hair styling agents

The perming of hair is a common styling procedure with negative impact on the overall properties of the hair fibers. Usually, this process uses harsh chemicals to promote the disruption of disulfide bonds and the formation of new bonds to change the shape of hair. Here, we explored bovine serum albumin (BSA), silk fibroin (SF), keratin and two fusion recombinant proteins (KP-UM and KP-Cryst) as new perming agents. A phosphate buffer prepared at different pH values (5, 7 and 9) was used to apply the proteins to virgin Asian hair, and a hot BaByliss was used to curl the hair fibers. To assess the potential of the protein formulations for hair styling, the perming efficiency and the perming resistance to wash were measured. Furthermore, the fiber water content was evaluated to assess if the proteins protected the hair during the styling process. Despite all of the proteins being able to assist in the curling of Asian hair, the best perming efficiency and perming resistance to wash results were observed for BSA and keratin. These proteins showed perming efficiency values close to that measured for a commercial perming product (chemical method), particularly at pH 5 and 9. The increase in the hairs internal and external water contents revealed a protective effect provided by the proteins during the application of heat in the styling procedure. This study shows the potential of proteins to be used in the development of new eco-friendly hair styling products.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.info:eu-repo/semantics/publishedVersio

Therapeutic textiles functionalized with keratin-based particles encapsulating terbinafine for the treatment of onychomycosis

The following supporting information can be downloaded at: https://www.mdpi.com/article/10.3390/ijms232213999/s1.Onychomycosis is the most common nail fungal infection worldwide. There are several therapy options available for onychomycosis, such as oral antifungals, topicals, and physical treatments. Terbinafine is in the frontline for the treatment of onychomycosis; however, several adverse effects are associated to its oral administration. In this work, innovative keratin-based carriers encapsulating terbinafine were designed to overcome the drawbacks related to the use this drug. Therapeutic textiles functionalized with keratin-based particles (100% keratin; 80% keratin/20% keratin-PEG) encapsulating terbinafine were developed. The controlled release of terbinafine from the functionalized textiles was evaluated against different mimetic biologic solutions (PBS buffer—pH=7.4, micellar solution and acidic sweat solution—pH=4.3). The modification of keratin with polyethylene glycol (PEG) moieties favored the release of terbinafine at the end of 48 h for all the solution conditions. When the activity of functionalized textiles was tested against Trichophyton rubrum, a differentiated inhibition was observed. Textiles functionalized with 80% keratin/20% keratin-PEG encapsulating terbinafine showed a 2-fold inhibition halo compared with the textiles containing 100% keratin-encapsulating terbinafine. No activity was observed for the textiles functionalized with keratin-based particles without terbinafine. The systems herein developed revealed therapeutic potential towards nail fungal infections, taking advantage of keratin-based particles affinity to keratin structures and of the keratinase activity of T. rubrum.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 by LABBELS – Associate Laboratory in Biotechnology, Bioengineering and Microelectromechanical Systems, LA/P/0029/2020.

Gestão da investigação, desenvolvimento e inovação nas organizações

A competitividade empresarial Portuguesa cada vez mais se confronta com um contexto caracterizado pela globalização, pela economia do conhecimento e pelas mudanças tecnológicas. Em particular, e no contexto de crise em que vivemos, a atitude e postura das organizações tem que mudar. É sabido que os países pequenos podem tender a ser mais inovadores, por serem mais flexíveis. Portugal tem que reconhecer nesta característica uma vantagem, aproveitar o potencial e, em simultâneo, transformar o conhecimento em inovação e vantagens competitivas. Muito tem sido feito neste sentido, desde a criação de instituições, a apoios financeiros, à formação de recursos humanos. Apesar deste esforço de modernização e evolução das organizações, o domínio da inovação continua a ser um “Calcanhar de Aquiles” do tecido empresarial português. Com o surgimento da norma NP 4457:2007, guia de orientação para a gestão da IDI, projectaram-se expectativas que não foram realizadas uma vez que, até à data, poucas empresas adoptaram os seus requisitos. É necessário compreender o porquê! A existência de um SGIDI vai fomentar o espírito inovador nas organizações, tão necessário para a competitividade das empresas? Ou quem já desenvolve a IDI pode prescindir do referencial? A implementação de qualquer sistema de gestão, traz benefícios a médio e longo prazo para as empresas. Identificando, planeando, organizando, monitorizando as actividades dos processos, numa perspectiva de melhoria contínua, em prol de resultados positivos para as organizações. Mas, por outro lado, os sistemas exigem recursos e implicam custos, e os resultados e benefìcios não são imediatos…o que leva as empresas a não identificarem as suas vantagens no curto prazo. Foram questões como estas que estiveram na base deste trabalho e é a elas que se pretende dar resposta.The Portuguese enterprise competitiveness is increasingly confronted with a context characterized by globalization, the knowledge economy and technological changes. In particular, and in the crisis context we experience, the organizations’ attitudes have to change. It is known that small countries can tend to be more innovative, since they are more flexible. Portugal has to recognize in this characteristic an advantage, use its potential, and simultaneously transform knowledge into innovation and competitive advantages. Much has been done in this direction, from the creation of institutions, financial supports, to the human resources formation. Despite of this organizations’ modernization and evolution effort, dominating innovation continues to be the “Aquilles’ heel” of the Portuguese business environment. With Norm NP 4457:2007, orientation guide for the IDI (Investigation, Development and Innovation) management, projected expectations have not been accomplished, since, until now, few companies adopted its requirements. It is necessary to understand the reason! The existence of a SGIDI (Management System for Investigation, Development and Innovation) does foment the innovative spirit in the organizations, much-needed for the competitiveness of the companies? Or, who already develops the IDI can do without the referential? The implementation of any management system brings medium and long turn benefits for the companies. Identifying, planning, organizing, monitoring the processes’ activities, in a continuous improvement perspective, in favor of positive results for the organizations. But, on the other hand, systems demand resources and imply costs, and the results and benefits are not immediate… what leads companies not to identify its advantages in the short term. Questions such as these have been in the basis of this work and it is to those that it intends to give an answer
