Facilitando a mobilização de redes de conhecimento: as reformas políticas, parcerias e formação de professores

Educational researchers and policy-makers are now expected by funding agencies and their institutions to innovate the multidirectional ways in which our production of knowledge can impact the classrooms of teachers (practitioners), while also integrating their experiential knowledge into the landscape of our research. In this article, we draw on the curriculum implementation literature to complicate our understandings of knowledge mobilization (KMb). Policy implementation, we suggest, can be understood as one specific type of KMb. We draw on different models for KMb and curriculum implementation and develop a relational model for KMb. Utilizing our model we critically reflect on the specific successes and challenges encountered while establishing, building, and sustaining the capacity of our KMb network. Our findings suggest that faculties of education are uniquely positioned to act as secondary brokers for the implementation of policy reforms within public education systems. To this end, we discuss how a relational KMb network is a “best practice” for establishing and sustaining partnerships among policy makers, educational researchers, and public school practitioners.Los organismos de financiación y sus instituciones esperan que investigadores educativos y responsables de decisiones políticas en el área innoven  la forma multidireccional en la que la producción de conocimiento puede afectar a las aulas de los docentes, y al mismo tiempo integrar su conocimiento experiencial en el modelo de la investigación. En este artículo, nos basamos en la literatura la implementación del currículo de reflexionar sobre nuestro entendimiento de la movilización de los conocimientos (por su sigla en inglés KMB). La implementación de políticas, se sugiere, se puede entender como un tipo específico de KMB. Nos basamos en diferentes modelos para la aplicación KMB e implementación curricular y desarrollamos un modelo relacional para KMB. Utilizando nuestro modelo reflexionamos críticamente sobre los éxitos y desafíos específicos encontrados mientras se establece, la construcción y el mantenimiento de la capacidad de nuestra red de KMB. Nuestros hallazgos sugieren que las facultades de educación están en una posición única para actuar como agentes secundarios en la implementación de reformas de política dentro de los sistemas de educación pública. Con este fin, se discute cómo una red KMB relacional es una "mejor práctica" para el establecimiento y mantenimiento de alianzas entre responsables políticos, los investigadores de la educación, y los profesionales de las escuelas públicas. Agências de fomento e instituições de ensino esperam que os pesquisadores em educação assim como os que decidem políticas na área inovem na forma multidirecional  que a produção de conhecimento na pode afetar o professor em sala de aula, e ao mesmo tempo integrar os conhecimentos experienciais no modelo de pesquisa. Neste artigo, nós confiamos na implementação do currículo literatura para refletir sobre a nossa compreensão da mobilização de conhecimentos (a sigla KMB). Implementação de políticas, sugere-se, pode ser entendida como um tipo específico de KMB.

Interdisciplinary Design Studio: Programming Document Visioning for a Robotic Demonstration, Research, and Engagement Dairy

The 2022 COLLABORATE Design Studio brought together students from various disciplines to address a complex, real-world project which required collaborative input from different perspectives. The studio worked to advance the co-creation of knowledge between external stakeholders, students, and instructors. The course was co-taught by faculty from different disciplines, and areas of expertise. During the semester, Nate Bicak and Steven Hardy worked with students from Architecture and Interior Design in collaboration with students in Dr. Tami Brown-Brandl’s students in Biological Systems Engineering and Animal Science to explore the values, spatial qualities, and area requirements of a Robotic Demonstration, Research, and Engagement Dairy. Students organized a series of meetings and participatory activities to gather information from a range of project stakeholders including: Heather Akin (Agricultural Leadership, Education & Communication), Kris Bousquet (NE Dairy Association), Paul Kononoff (Animal Science), Eric Markvicka (Mechanical and Material Engineering), Julia McQuillan (Sociology), Santosh Pitla (BioSystems and Agricultural Engineering), Ling Ling Sun (NE Public Media), and Rosanna Villa Rojas (Food Science & Technology). The information gathered helped to frame the overall problem - both quantitative and qualitative - to be addressed during the design visioning stage (not included in this document). Student contributors included: Sarah Alduaylij, Noor Al-Maamari, Devyn Beekman, Kelsey Belgum, Lauren Chubb, Nicholas Forte, Mitchell Hill, Joshua Holstein, Dylan Lambe, Phuong Le, Mia LeRiger, Elizabeth Loftus, Josh Lorenzen , Megan Lovci, Alex Martino, Zade Miller, Hannah Morgan , Annabelle Nichols , Collin Shearman, Rebecca Sowl, Nalin Theplikhith, Angela Vu, Shaylee Wagner, Ethan Watermeier, Trever Zelenk

Large-Scale Structure, Performance and Brahms's Op. 119 No. 2

Research in musical performance studies has generated a healthy scepticism of the importance of large-scale structure to performance (in terms of both interpretation and perception): on the one hand, it might well be hardwired into notation, and on the other, prioritising it risks simply repeating outworn maxims that neglect the performer’s musical contributions. Recently, some scholars have begun to rethink the potential structural relevance of performance rather than necessarily determining structure on the basis of the musical score alone. In this article, I consolidate some of this thinking and draw out its implications for performers’ handling of large-scale structure; in doing so, I suggest that we should consider moving away from conventional large-scale score-based forms as structural certainties. I support this through a case study of Johannes Brahms’s Intermezzo in E minor, Op. 119 No. 2 in which I analyse recorded performances by Wilhelm Backhaus, Maria Yudina and Ilona Eibenschütz. I conclude by arguing that the inclusion and prioritisation of any particular musical material – whether the score, performance, or other – requires serious consideration and reflection in any analytical act

The Ponto-Caspian basin as a final trap for southeastern Scandinavian Ice-Sheet meltwater

This paper provides new data on the evolution of the Caspian Sea and Black Sea from the Last Glacial Maximum until ca. 12 cal kyr BP. We present new analyses (clay mineralogy, grain-size, Nd isotopes and pollen) applied to sediments from the river terraces in the lower Volga, from the middle Caspian Sea and from the western part of the Black Sea. The results show that during the last deglaciation, the Ponto-Caspian basin collected meltwater and fine-grained sediment from the southern margin of the Scandinavian Ice Sheet (SIS) via the Dniepr and Volga Rivers. It induced the deposition of characteristic red-brownish/chocolate-coloured illite-rich sediments (Red Layers in the Black Sea and Chocolate Clays in the Caspian Sea) that originated from the Baltic Shield area according to Nd data. This general evolution, common to both seas was nevertheless differentiated over time due to the specificities of their catchment areas and due to the movement of the southern margin of the SIS. Our results indicate that in the eastern part of the East European Plain, the meltwater from the SIS margin supplied the Caspian Sea during the deglaciation until ∼13.8 cal kyr BP, and possibly from the LGM. That led to the Early Khvalynian transgressive stage(s) and Chocolate Clays deposition in the now-emerged northern flat part of the Caspian Sea (river terraces in the modern lower Volga) and in its middle basin. In the western part of the East European Plain, our results confirm the release of meltwater from the SIS margin into the Black Sea that occurred between 17.2 and 15.7 cal kyr BP, as previously proposed. Indeed, recent findings concerning the evolution of the southern margin of the SIS and the Black Sea, show that during the last deglaciation, occurred a westward release of meltwater into the North Atlantic (between ca. 20 and 16.7 cal kyr BP), and a southward one into the Black Sea (between 17.2 and 15.7 cal kyr BP). After the Red Layers/Chocolate Clays deposition in both seas and until 12 cal kyr BP, smectite became the dominant clay mineral. The East European Plain is clearly identified as the source for smectite in the Caspian Sea sediments. In the Black Sea, smectite originated either from the East European Plain or from the Danube River catchment. Previous studies consider smectite as being only of Anatolian origin. However, our results highlight both, the European source for smectite and the impact of this source on the depositional environment of the Black Sea during considered period

Minimal information for studies of extracellular vesicles (MISEV2023): From basic to advanced approaches

Extracellular vesicles (EVs), through their complex cargo, can reflect the state of their cell of origin and change the functions and phenotypes of other cells. These features indicate strong biomarker and therapeutic potential and have generated broad interest, as evidenced by the steady year-on-year increase in the numbers of scientific publications about EVs. Important advances have been made in EV metrology and in understanding and applying EV biology. However, hurdles remain to realising the potential of EVs in domains ranging from basic biology to clinical applications due to challenges in EV nomenclature, separation from non-vesicular extracellular particles, characterisation and functional studies. To address the challenges and opportunities in this rapidly evolving field, the International Society for Extracellular Vesicles (ISEV) updates its 'Minimal Information for Studies of Extracellular Vesicles', which was first published in 2014 and then in 2018 as MISEV2014 and MISEV2018, respectively. The goal of the current document, MISEV2023, is to provide researchers with an updated snapshot of available approaches and their advantages and limitations for production, separation and characterisation of EVs from multiple sources, including cell culture, body fluids and solid tissues. In addition to presenting the latest state of the art in basic principles of EV research, this document also covers advanced techniques and approaches that are currently expanding the boundaries of the field. MISEV2023 also includes new sections on EV release and uptake and a brief discussion of in vivo approaches to study EVs. Compiling feedback from ISEV expert task forces and more than 1000 researchers, this document conveys the current state of EV research to facilitate robust scientific discoveries and move the field forward even more rapidly

Evaluation of a modified Cheatham-Platinum stent for the treatment of aortic coarctation by finite element modelling

Objectives: Stent implantation for the treatment of aortic coarctation has become a standard approach for the management of older children and adults. Criteria for optimal stent design and construction remain undefined. This study used computational modelling to compare the performance of two generations of the Cheatham-Platinum stent (NuMED, Hopkinton, NY, USA) deployed in aortic coarctation using finite element analysis. Design: Three-dimensional models of both stents, reverse engineered from microCT scans, were implanted in the aortic model of one representative patient. They were virtually expanded in the vessel with a 16 mm balloon and a pressure of 2 atm. Results: The conventional stent foreshortened to 96.5% of its initial length, whereas the new stent to 99.2% of its initial length. Diameters in 15 slices across the conventional stent were 11.6-15 mm (median 14.2 mm) and slightly higher across the new stent: 10.7-15.3 mm (median 14.5 mm) (p= 0.021). Apposition to the vessel wall was similar: conventional stent 31.1% and new stent 28.6% of total stent area. Conclusions: The new design Cheatham-Platinum stent showed similar deployment results compared to the conventional design. The new stent design showed slightly higher expansion, using the same delivery balloon. Patient-specific computational models can be used for virtual implantation of new aortic stents and promise to inform subsequent in vivo trials
