My PhD research focused on the development of environmentally sustainable methods for peptide synthesis. The traditional and toxic solvents and bases used in solid-phase peptide synthesis (SPPS) were replaced with eco-friendly alternatives to reduce the environmental impact. In particular, N-octylpyrrolidone was found to be an effective green solvent in combination with dimethyl carbonate, resulting in a 63-66% reduction in process mass intensity (PMI). In addition, a green base, DEAPA, was identified for Fmoc removal, which showed comparable results to piperidine, while being less regulated and toxic, and able to better control aspartimide-related side reactions. The study extended beyond SPPS to explore liquid-phase peptide synthesis (LPPS) and solution-phase peptide synthesis (SolPPS) using propylphosphonic anhydride (T3P®) as a coupling reagent. The developed green SolPPS using Cbz amino acids achieved exceptional efficiency, minimal racemisation and a PMI of 30 to introduce a single amino acid in the iterative process. This PMI value is the lowest ever reported for an oligopeptide synthesis protocol. This technique was extended to N-Boc amino acids in DCM, requiring aqueous workups and achieving 95% purity of Leu-Enkephalin. Finally, T3P® was found to be suitable for LPPS. An anchor, mimicking a resin, was used to allow precipitation or solubilisation of the growing anchored-peptide, depending on the polarity of the solvent used. Anisole and DCM resulted in a pentapeptide purity of over 95%. While at Oxford University, I synthesized a cleavable fragment that is sensitive to cathepsin B (CatB) and incorporated it into a cyclic antisense oligonucleotide (ASO) targeting the metastasis-associated lung adenocarcinoma transcript 1 (MALAT1). ASO demonstrated good stability in a simulated in vivo environment using human serum and high affinity with complementary RNA. The Cyclic-ASO was opened by CatB in optimal conditions. Experiments highlight therapeutic potential and a novel method for controlling cyclic oligonucleotide activity, potentially enhancing cellular uptake.

L'Open innovation (OI) rappresenta un concetto complesso, pieno di sfaccettature e dimensioni di analisi. Il seguente elaborato adotta un approccio micro-fondazionale (Abell et al., 2008) al fine di studiare l'Individuo nella sua relazione con questo costrutto. Nello specifico l'obiettivo è quello di studiare comportamenti che l'individuo adotta al fine di perseguire determinati "Social Outcomes"(pratiche di Open innovation implementate a livello di organizzazione). Allo studio dei comportamenti si aggiunge la proposta di un set di KPI, atti a misurarli in modo dinamico. Un driver fondamentale è il focus sul contesto scientifico: nello specifico vengono studiati i comportamenti collaborativi messi in atto da scienziati lungo il processo innovativo (Beck et al., 2022). Lo studio deriva da una meta analisi e interviste etnografiche. L'analisi è stata condotta su Scopus e Scholar dove è stato inserito un ampio set di parole chiave (e.g. ”Open innovation & Measures/scales”, "Open innovation in Science (OIS)", “University-Industry collaboration”, …). Sono stati estratti articoli rilevanti che proponevano scale per misurare diversi costrutti collegati ad OI(Antons et al., 2017) (Boardman and Corley, 2008). Sono stati estratti gli items dalle scale e convertiti in comportamenti relativi alla pratica di OIS, sulla base del framework proposto da Beck et al. (2022). Sono stati ottenuti 48 comportamenti unici da 8 scale diverse: sono stati clusterizzati al fine di ottenere 10 cluster di comportamenti omogenei. La clusterizzazione è stata condotta a partire da una matrice di similarità creata da 5 esperti, sottoposta al Software Ucinet. I cluster così formati sono stati la base per generare un set di 24 kpi, derivanti dai comportamenti, e suddivisi tra i vari cluster. Sono stati definiti 5 ulteriori indicatori a partire da interviste proposte a 13 partecipanti tra ricercatori e professori. Questi ultimi KPI derivano dai valori trainanti per i ricercatori, emersi come insights.

Resumo: A intervenção em crianças disléxicas nem sempre é fácil uma vez que, à partida, serão crianças desmotivadas por insucessos repetidos, complexos de inferioridade, timidez, baixa autoconfiança e auto-estima, com pouca capacidade de atenção e concentração. A família, a escola e a sociedade em geral têm um papel decisivo, não deverão exigir nem impor metas complicadas, adaptando sempre uma postura de compreensão da criança. A criança disléxica aprende num ritmo diferente, como tal, precisa que a escola adeqúe as suas práticas educativas tendo em conta as suas características e especificidades. Pretende-se com este trabalho aprofundar conhecimentos sobre a temática da dislexia e sua aplicação, dentro da sala de aula, na disciplina Educação Visual e Tecnológica, numa turma do 2º Ciclo do Ensino Básico que inclui uma aluna considerada disléxica. Começámos por caracterizar a turma, a aluna e os contextos envolventes em que as mesmas se inserem, seguidamente fez-se uma intervenção estruturada, a longo e curto prazo, numa dinâmica de planificação, acção e reflexão, numa perspectiva de educação inclusiva, com práticas educativas cooperativas e diferenciadas. Ao longo das sessões de trabalho, a turma teve a oportunidade de se manifestar nas assembleias de turma, na negociação das actividades, de trabalhar em pares, em grande e pequeno grupo, criando desta forma um clima de inter-ajuda e de cooperação na sala de aula, funcionando com as duas professoras da disciplina, partilhando momentos de aprendizagem e socialização de saberes. A aluna considerada disléxica passou a interagir na turma com os colegas, de forma positiva, e estes com ela. As suas dificuldades foram superadas com a ajuda dos colegas, partilhando os seus saberes, dúvidas e experiências. Foi uma experiência positiva para o grupo, para a aluna e para as professoras da turma. Abstract: The intervention in dyslexic children is not always easy from the start, a priori, children will be discouraged by repeated failures, inferiority complexes, shyness, low selfconfidence and self- esteem, with little attention span and concentration. The family, school and society in general have a decisive role, should not require or impose complicated goals, always adapting an attitude of understanding of the child. The dyslexic children learn at a different pace, as such, requires the school to adjust its educational practices in view of their characteristics and specificities. The aim of this work to deepen knowledge on the subject of dyslexia and its application in the classroom, Visual and Technological Education as the subject, in a class of the 2nd Cycle of Basic Education that includes a student considered dyslexic. We have began by characterizing the class, the student and the surrounding contexts in which they are involved, then became a structured intervention in the long and short term, in order of creating a dynamic planning, action and reflection, with a inclusive education perspective, with cooperative practical education and differentiated. During the work seasons, the class had the opportunity to express themselves in class meetings, the negotiation activities, working in pairs, in large and small groups, thus creating a climate of mutual help and cooperation in the classroom, working with two teachers of the subject, sharing moments of learning and socialization of knowledge. The student consider as dyslexic has started to interact in the class with the colleagues in a positive way, and they with her. Their difficulties were overcome with the help of colleagues, sharing their knowledge, doubts and experiences. It was a positive experience for the group, to the student and the teachers of the class.

In the last years, an increase of the interest to develop educational practices in higher education, based on the approach of the reflective learning, is observed. Nevertheless, we scarcely find in our context researches or experiences that allow knowing students’ perceptions about this teaching and learning approach. We have developed an experience in the bachelor of Social Education at the University of Girona with the aim to contribute to the personal and professional development of future social educators in their initial training, using reflective learning methodology. In this article we present an evaluation of the experience based on students’ perceptions. They assessed the usefulness they think the module has for their training, the methodology and the activities. This evaluation has been carried out through in-depth interviews to 17 students who participated in the module in 2010-11 academic year. The results show that students assess positively the experience, either its general usefulness or the methodology of reflective learning, although they acknowledge some difficulties to carry out such a process which involves a high degree of introspection and a difficulty to set the boundaries in the narration of personal questions. The study also shows some challenges related on the need, but also the difficulty, to include personal and professional development as a powerful axis in the higher education curriculum, as well as elements linked to reflective learning assessment

This study is built up on the need to enhance the thinking over the decisions taken and the performances carried out by teachers and students in secondary education with regard to the evaluation of the learning result. The problem lies in that the information and - or - the results gathered from the evaluation practices do not always entail a serious consideration of these data. Hence the lack of a systematic modification of the educational practices. In this study a range of self-questioning tools are proposed in order to enhance ¡the teachers and students' ability to think about this topic as well as their ability to evaluate themselves. The proceeding has been the following: a) the issues that generate conflict have been identified according to the dimensions and categories of this research; b) a model to build the tools has been elaborated; c) finally, questions have been constructed for each one of the conflicts previously specified. This has been done bearing in mind the theoretical framework that has been chosen to carry out this research. The mechanism that is proposed here is formed by five tools for the teachers and one for the students. Each tool consists of a) the definition of the problem; b) the goal of the tool, and c) the three levels of consideration. In the first level, general questions are put forward in order to be discussed either individually or in a group. The goal of this activity is to gain consciousness of the key issues in order to solve the problems. In the second level, a more structured guide is proposed. Its goal is to direct the practice of the reflection of the issues that generate a conflict. Finally, in the third level, a method is proposed to increase the reflection and the viewpoints of this reflection, like written documents, web pages, specific references, experiences, and opinions about the topic.

This paper presents a reconstruction of the historical trajectory of the Escola Industrial de Natal (Industrial School of Natal), in the period 1942 to 1968, based on the analysis of its cultural, social and pedagogical characteristics in a process in which its educational practices and the individuals who constructed them were getting involved in their actions. In this sense, the concepts of memory and school culture occupied a central place to understand the elements that characterized its administrative and pedagogical organization such as, for example, its curriculum, aims, disciplinary rules, clientele, teachers, leaders and the configuration of the institutional power. Designed to meet the demands of an industrial process that has strengthened in the country, throughout its history, the Escola Industrial de Natal was becoming a space predominantly occupied by individuals, from economically disadvantaged social groups in society, in search of a professional training that would guarantee them the exercise of a profession. The time frame from 1942 to 1968 allowed us to verify the changes caused by the Organic Law of Industrial Education of 1942, and the Law number 3.552, from 1959, in the organizational structure of this school. In this context, a characteristic that was evident was the purpose of making it flow between the students the love for the country, the respect for civic values and the belief that industrial education would be able to boost the country's development, an aspect that reached a bigger dimension from the 1950 s. Marked the disciplinary character of this institution the control over the actions of individuals, developed through its multiple educational practices in specific areas and in the predetermined time, under the constant gaze of those who participated, in some from, in driving this process. On the other hand, the vocational and human training, provided to students, allowed new opportunities for social integration, not only in the state of Rio Grande do Norte, but also in other regions of Brazil. Conversely, during his career, the Escola Industrial de Natal has remained being seen as an organized institution, with good teachers, but intended for the children of others

Há poucas investigações quanto às práticas educativas escolas, ou seja, os procedimentos que são utilizados pelo educador para promover a aprendizagem de seus alunos. Deste modo, o objetivo deste trabalho é analisar as práticas educativas escolares, e verificar em que medida essas práticas contribuem para a inclusão do aluno com Necessidades Educacionais Especiais. O presente estudo optou pelo estudo exploratório contemplando observações em sala de aula, bem como, no ambiente escolar. As observações ocorriam semanalmente sem datas fixas, e em horários diferentes, a fim de que fosse possível observação num ambiente típico. Utilizou-se também a entrevista e a análise de documentos do aluno (redação, provas, atividades acadêmicas) e da escola. Participaram do presente estudo um aluno que apresenta dismotria cerebral ontogenética, sua mãe, bem como, as professoras que lecionaram à ele durante os anos de 2000 e 2001. Os dados coletados auxiliaram para definir a categoria que foi foco da presente pesquisa: desempenho e rendimento escolar e percepção do aluno sobre seu processo de aprendizagem. Como conclusão o presente estudo constatou que o processo de inclusão do aluno, no tocante à inclusão física social, responde até certo grau às suas necessidades. No entanto, do ponto de vista de aprendizagem, não houve inclusão educacional, as práticas educativas observadas não contemplavam a especificidade curricular e de aprendizagem a fim de atender às necessidades do aluno.

Muitas práticas educacionais no ensino e aprendizagem de línguas parecem ainda dominadas por uma visão de cultura essencialista, na qual os alunos, suas habilidades e atitudes de aprendizagem são caracterizadas por estereótipos problemáticos e/ou imaginários de suas culturas religiosas, étnicas e nacionais. As novas ferramentas e aplicativos para comunicação trazidos pela internet têm contribuído para o aumento de práticas comunicativas entre indivíduos de diferentes culturas e o uso da língua inglesa entre falantes não nativos, o que também tende a trazer impactos sobre a maneira como entendemos e ensinamos cultura na aprendizagem de tal língua. Este artigo pretende explicitar a visão de cultura presente nos conceitos de competência comunicativa e competência intercultural, e discutir a necessidade de reformulação do componente cultural no ensino e aprendizagem de línguas, para que ele objetive a exploração da complexidade advinda do pragmatismo dos encontros interculturais na contemporaneidade.
