Qualitative Methodology in Education: A Multi-Case Study Focused on the Formative Mediation Area in Portugal and in France

Formative Mediation has arisen as a new and complex area in the field of Education and is questioning the traditional conceptions of curriculum, pedagogical relationship, conflict, citizenship and autonomy.The study we have developed is related to the emerging perspectives that are associated with the field of Education and Training of Adults, where we sought to understand what are the pedagogical dynamics, the professional profiles and the practices correlated with Formative Mediation in Courses of Adult Education and Training (AET Courses) and in the process of Recognition, Validation and Certification of Competences (RVCC) developed in Portugal and in the Validation des Acquis de l'Experience (VAE) undertaken in France.To accomplish this investigation, we used a predominantly qualitative and emerging design, where inductive analysis prevailed throughout the investigative process. In this sense, we carried out a multi-case study (three cases in Portugal and three cases in France) with nine participants in the investigation: two ETA Mediators, a Diagnosis and Referral Specialist (DRS), three Recognition and Validation of Competences Professionals (RVCPs) and three Professionals working in the VAE process. Autobiographical narratives, participant observations and semi-directive interviews were the techniques used and the data obtained was processed using the emerging and inductive categorisation. In this text, we intend to present the steps and processes used in the data analysis, characterise them and discuss some of the results achieved, while seeking to reflect on the advantages and potentialities of the use of qualitative research methods in the Educational field.

Carbon dioxide (co2) emissions by rock-derived organic carbon oxidation

The global carbon cycle controls Earth’s climate by the emission and drawdown of carbon dioxide (CO2) from the atmosphere. One of the major sources of CO2 is thought to be the oxidation of organic carbon contained in rocks during chemical weathering. Since the industrial revolution, this flux has been accelerated by burning fossil fuels. However, the natural rates of CO2 emission by rock-derived organic carbon oxidation are very poorly constrained – the only major CO2 source that has not been properly quantified – and the dominant controls on this flux remain unclear. The CO2 release is likely to be ~100 TgC/yr, similar to degassing from volcanoes. Without knowing the rate of CO2 emission and the controls on this flux, it is not possible to fully understand the evolution of atmospheric CO2 and global climate over geological timescales, nor to project future changes over hundreds to thousands of years. To address this deficit and quantify a major geological CO2 source, the proposal will:
1) Assess which factors govern rock-derived organic carbon oxidation.
2) Determine how environmental changes impact oxidation rates and CO2 release.
3) Quantify the global CO2 emissions by rock-derived organic carbon oxidation during chemical weathering, and assess how they may have varied both over Earth history and via anthropogenic change. 
By quantifying a major CO2 emission for the first time, this project will provide a step change in our understanding of the geological, as opposed to the anthropogenically-modified, carbon cycle. Measurement of rock-derived organic carbon oxidation will require a new approach, harnessing state-of-the-art geochemical proxies carried by rivers (rhenium). Data from river catchments spanning large gradients in the likely environmental controls (erosion, temperature), will elucidate the main factors governing this process, and enable construction of a data-driven numerical model to provide the first quantification of CO2 emissions by this process.
Derivation of the thermal characteristics of mesoscale eddies

This study aims at explaining the relationship between thermodynamic characteristics and direction of rotation of mesoscale eddies (MEs). The geometric characteristics of the MEs are under the following assumptions: the structure of the MEs is symmetrical, and changes of oceanic physical variables are close to linear features in the radial direction in the ME regions. Based on these assumptions, by using primitive equations without friction under a cylindrical coordinate system, the thermodynamic characteristics of the MEs are derived, showing that the conventional relationship of warm anticyclonic eddies with high sea surface height (SSH) and cold cyclonic eddies with low SSH is not consistent with the SSH and sea surface temperature (SST) observations of eddies. The results show that the symmetrical form is an ideal approximation for the geometric characteristics of MEs. In consideration of the above assumptions, there are advantages for derivation of the characteristics of the MEs under a cylindrical coordinate.

Peces de planicies de inundación tropical de la cuenca baja del río Magdalena, Colombia

Se estudió la diversidad de peces y se evaluaron los factores determinantes en la estructuración de los ensamblajes de peces capturados en una llanura de inundación tropical de la cuenca del río Magdalena, Colombia. Se identificó que la riqueza íctica reportada en este estudio (43 especies) corresponde aproximadamente al 38 % de la diversidad de la cuenca baja del río Magdalena (112 especies) y a cerca del 19 % de la diversidad total del sistema Magdalena-Cauca. Las planicies con mayor conectividad entre sí y con el río presentaron comunidades más similares que los hábitats más distantes y aislados. Asimismo, la estructura de las comunidades de peces estuvo determinada por las condiciones del medio ambiente y el tipo de hábitat en términos de conectividad. Las variables ambientales que más influyeron en la estructura de las comunidades fueron las que estuvieron asociadas a procesos de eutrofización, tales como dureza, cloruros, nitratos, nitrógeno total, sólidos suspendidos totales y salinidad, y al pulso del caudal, como la profundidad, pero el principal factor de regulación fue la poca o nula conexión entre las zonas inundables y el cauce principal del río Magdalena. Se considera que la información generada pueda ser empleada para estimar la composición real de especies de peces dulceacuícolas, sustentar la toma de decisiones por parte de las entidades gubernamentales, priorizar áreas para la conservación de la biodiversidad o contribuir al adecuado uso y manejo de los recursos naturales presentes en este complejo sistema lagunar tropical.
Connecting the extreme

Advances in technology and methodology over the last decade, have enabled the study of galaxies to the highest redshifts. This has revolutionized our understanding of the origin and evolution of galaxies. I have played a central role in this revolution, by discovering that at z=2, when the universe was only 3 Gyr old, half of the most massive galaxies were extremely compact and had already completed their star formation. During the last five years I have led a successful group of postdocs and students dedicated to investigating the extreme properties of these galaxies and place them into cosmological context. Combining a series of high profile observational studies published by my group and others, I recently proposed an evolutionary sequence that ties together the most extreme galaxies in the universe, from the most intense dusty starburst at cosmic dawn, through quasars: the brightest sources in the universe, driven by feedback from supermassive black holes, and galaxy cores hosting the densest conglomerations of stellar mass known, to the sleeping giants of the local universe, the giant ellipticals. The proposed research program will explore if such an evolutionary sequence exists, with the ultimate goal of reaching, for the first time, a coherent physical understanding of how the most massive galaxies in the universe formed. While there is a chance the rigorous tests may ultimately reveal the proposed sequence to be too simplistic, a guarantied outcome of the program is a significantly improved understanding of the physical mechanisms that shape galaxies and drive their star formation and quenching
Controlled interaction of benzaldehyde thiosemicarbazones with palladium: formation of bis-complexes with cis-geometry and organopalladium complexes, and their catalytic application in C–C and C–N coupling

Reaction of a 1 : 1 mixture of 4-R-benzaldehyde thiosemicarbazone (R = OCH3, CH3, H, Cl and NO2) and 2-picolinic acid with an equivalent quantity of Na2[PdCl4] in ethanolic medium, under relatively mild reflux, affords a group of complexes of type [Pd(NS–R)2] as the major product and another family of complexes of type [{Pd(CNS–R)}n] as the minor product (where NS–R and CNS–R denote the N,S- and C,N,S-coordinated thiosemicarbazone, respectively). The [{Pd(CNS–R)}n] complexes are conveniently obtained in good yields from similar reactions carried out under prolonged reflux. The sulfur-bridge in the [{Pd(CNS–R)}n] complexes undergoes facile cleavage upon their reaction with triphenylphosphine to yield complexes of type [Pd(CNS–R)(PPh3)]. Crystal structures of [Pd(NS–OCH3)2], [Pd(NS–CH3)2], [Pd(NS–Cl)2], [Pd(CNS–CH3)(PPh3)], [Pd(CNS–H)(PPh3)] and [Pd(CNS–Cl)(PPh3)] have been determined. In the [Pd(NS–R)2] complexes the thiosemicarbazones are coordinated to the metal center, via dissociation of the acidic proton, as monoanionic bidentate N,S-donors forming five-membered chelate rings, while in the [Pd(CNS–R)(PPh3)] complexes they are coordinated to palladium, via dissociation of the acidic proton and activation of an ortho C–H bond, as dianionic tridentate C,N,S-donors forming two adjacent five-membered chelate rings. The [Pd(NS–R)2] and [Pd(CNS–R)(PPh3)] complexes show characteristic 1H NMR signals, and in dichloromethane solution they all display intense absorptions in the visible and ultraviolet regions. The [Pd(NS–R)2] and [Pd(CNS–R)(PPh3)] complexes have shown notable efficiency in catalyzing C–C and C–N coupling reactions.
Effect of forest fragment size on Polistinae (Hymenoptera, Vespidae) in a transitional area of Cerrado and Atlantic Forest in south central Minas Gerais state, Brazil

Ecosystem fragmentation negatively affects biological diversity and compromises different environmental services. This situation occurs in two important biomes in Brazil, the Atlantic Forest and the Cerrado. There is little information on the effects of fragmentation on animal taxa, including social wasps. It was hypothesized that fragments that are small in size and subject to anthropogenic pressures have reduced social wasp richness and colony numbers. This study aimed to investigate the effect of forest fragmentation on Polistinae richness and colony number at Atlantic Forest and Cerrado sites in southern central Minas Gerais State, southeastern Brazil. The study was conducted in three fragments, Mata do Baú, Cachoeira da Lajinha, and Cachoeira do Padeiro, from October 2020 to March 2021, using active collection to record social wasp species and colony numbers. A total of 42 species and 80 colonies were recorded in the three fragments. Forest fragment size alone did not influence social wasp communities, but communities were significantly affected by a combination of factors, including fragment size, adjacent vegetation, and anthropogenic pressures. Species richness was higher in Mata do Baú and Cachoeira da Lajinha, which did not differ from each other, than in Cachoeira do Padeiro; however, all fragments had exclusive communities. Therefore, an increase in anthropogenic pressure in any of the three fragments may lead to losses in social wasp species.
In Vitro Comparison of Mechanical and Degradation Properties of Equivalent Absorbable Suture Materials from Two Different Manufacturers

To compare the mechanical, knotting, and absorption properties of 3 synthetic absorbable suture materials (polyglactin 910, polydioxanone, poliglecaprone 25) from 2 different manufacturers (Huaiyin Medical Instruments Co. Ltd. and Ethicon Inc.).Suture material samples from the same manufacturing lot for each suture type and manufacturer.Part 1: 10 samples of each suture were incubated in bovine serum and tested for ultimate load and stiffness at days 0, 1, 7, 14, 21, and 28. Part 2: 10 knotted samples were similarly evaluated, without incubation.Huaiyin polydioxanone had a greater (P<.001) ultimate load on days 0, 1, and 7; and a consistently greater stiffness for the duration of the study, compared with the Ethicon polydioxanone. Ethicon poliglecaprone 25 had a greater ultimate load on days 0, 1, 7 (P<.001); on day 21 Huaiyin had a greater ultimate load. Ethicon poliglecaprone had greater stiffness on days 0, 1, 7 (P<.001). Ethicon polyglactin 910 had a greater (P<.001) ultimate load at all times and a greater stiffness (P<.001) at days 0, 1, 7, and 14 compared with Huaiyin polyglactin 910. Huaiyin polydioxanone and polyglactin 910 had greater knot breaking strengths than Ethicon equivalents (P<.001).Differences in mechanical properties exist between nominally identical suture materials from different manufacturers.
Artificial intelligence techniques for ice core analyses

The detection of insoluble particles trapped in ice or sediment cores, like pollen grains, foraminiferal and diatom assemblages, volcanic and dust particles represents the basis for paleoresearch on the biosphere, volcanism and oceanic and atmospheric realms. To date, except for ice core dust, this analytical goal is achieved during years of particle observations by manual microscopy. Artificial Intelligence predictive models are already applied to several research fields within geoscience, but up to date its implementation to paleoclimate is missing. With ICELEARNING, I aim to develop a two-phase routine for the automatic quantification of insoluble particles trapped in ice cores. The routine is based on a commercial Flow Imaging Microscope producing particle images from within melted ice samples. The images are then analyzed by Pattern Recognition algorithms which will be developed for automatic particle classification and counting. The routine will be specifically developed in order to be implemented in Continuous Flow Analysis (CFA) systems, therefore surpassing the traditional methods by providing continuous particle records from ice cores. ICELEARNING methodology is suitable to any diluted sample, thus representing a ground-breaking analytical advancement from ice core science to marine geology. This innovative routine is automatic and non-destructive, imperative prerequisites for the future Antarctic ice core project analytical measurements, aiming to retrieve a continuous climatic and environmental record covering the last 1.5 Myr. ICELERNING will be developed at Ca’ Foscari University of Venice with Prof. Carlo Barbante, leading expert in trace and ultra-trace level impurity detections in ice cores and with the University of Bergen, a top institution in marine geology and paleoceanography. This unique synergy, in addition to the proposer’s knowledge of CFA systems and machine learning techniques will provide the best preconditions for the project success.
Cavity-Enhanced optical microscope

Visualization of material objects is instrumental for our perception and understanding of nature. Nanoscale matter, however, escapes direct visualization by optical imaging due to weak interaction with light. Thus, studies of nanoparticles and molecules with common light absorption or emission microscopes are predominantly limited to macroscopic samples. Our recent developments of cavity-enhanced light-matter coupling provide means to boost the sensitivity of optical microscopy to the level of single nanoparticles and molecules. Our innovative technology enables detection, spectroscopy and label-free imaging of individual nano-objects that are instrumental for the development of novel functional materials and devices. In contrast to most alternative techniques of sensitive visualization, it operates with versatile and affordable light sources and detectors. Moreover, the technological platform is not limited to specific materials or sophisticated sample preconditioning and thus is applicable to fields as diverse as quantum physics and medicine. It capitalizes on the enhancement of light-matter coupling by an optical cavity to enable direct and quantitative optical absorption imaging of nanoscale matter. This ERC Proof of Concept project aims at leveraging the vast potential of our innovative technology towards its commercialization with the ultimate goal to create a consistent product concept and to advance our highly sensitive cavity-enhanced optical microscope into an affordable and widely spread enabling analytic tool.
Development and Evaluation of an Interactive WebQuest Environment: "Web Macerasi"

This study was conducted to develop a web-based interactive system, Web Macerasi, for teaching-learning and evaluation purposes, and to find out the possible effects of this system. The study has two stages. In the first stage, a WebQuest site was designed as an interactive system in which various Internet and web technologies were used for infusion of technology into teaching and learning process. The Web Macerasi site was used for project work by 92 prospective students who attended different courses in different years. For collecting the students’ perceptions about the implementations of the system, a questionnaire of WebQuest effectiveness and a focus group interview guide were developed. Next, the first phase of the study was concluded, and the WebQuest system was updated based on the data gathered from students. In the second phase, 27 students from a different course used the system, and their perceptions were collected through the questionnaire and analyzed. It was found that the students favored the technology-supported media, were more willing to collaborate, found the feedback very useful, and agreed on the positive contribution of planned works. Consequently, the Web Macerasi site was found to be successful and to have been used effectively in terms of its aims. Further studies should be carried out for diffusion of this technology into the teaching-learning processes.
Updated bioavailability and 48 h excretion profile of flavan-3-ols from green tea in humans

Green tea is a popular beverage, prepared with infusion of unfermented dried leaves of Camellia sinensis, and is one of the most relevant sources of polyphenolic compounds in the human diet. This study reports green tea flavan-3-ol absorption, metabolism and complete urinary excretion up to 48 h in 20 healthy volunteers. Urinary and tea samples were analysed by high-performance liquid chromatography coupled with tandem mass spectrometry. Green tea contained monomeric flavan-3-ols and proanthocyanidins with a total polyphenol content of 728 μmol. A total of 41 metabolites were identified in urines, all present in conjugated forms. Among these, six colonic metabolites of green tea flavan-3-ols were identified for the first time after green tea consumption in humans. The average 48 h bioavailability was close to 62%, major contributors being microbial metabolites. Some volunteer showed a 100% absorption/excretion, whereas some others were unable to efficiently absorb/excrete this class of flavonoids. This suggests that colonic ring fission metabolism could be relevant in the putative bioactivity of green tea polyphenols.
