Mokni, Ridha El, Guacchio, Emanuele Del, Iamonico, Duilio (2023): Further insights into the Stellaria media aggregate (Caryophyllaceae, Alsinoideae, Alsineae) in Africa: first reports of S. ruderalis in North Africa and S. cupaniana in Tunisia, with nomenclatural notes on the name Alsine cupaniana. Phytotaxa 584 (4): 264-274, DOI: 10.11646/phytotaxa.584.4.3, URL: http://dx.doi.org/10.11646/phytotaxa.584.4.3

Over the course of the recent decade, the composition of Alsineae has been drastically changed by means of molecular phylogeny. However, the genus Brachystemma has not been sampled in any of the previous studies, and its phylogenetic position is still pending. In addition, the related species Stellaria ovatifolia, which has at times been placed in Brachystemma, Schizotechium, or Stellaria, has also not been sampled. Here, nuclear ribosomal internal transcribed spacer (ITS) and four plastid regions (trnL-F, matK, rbcL, rps16) were used to conduct phylogenetic analyses within Caryophyllaceae and the tribe Alsineae. Ancestral characters (petal margin and number of seeds) were reconstructed in the tribe Alsineae based on the phylogenetic results. Our results indicate that Brachystemma is nested in the tribe Alsineae and forms a monophylum with S. ovatifolia, and apically lobed petals and numerous seeds may be the ancestral characters in the tribe Alsineae. Based on our study, Stellaria ovatifolia should be considered within Brachystemma, and Brachystemma is clearly a separate genus and now includes two species.

L'estructura bàsica d'aquest treball correspon a les clàssiques propostes de vida i obra, doncs considerem que és el primer pas que havíem de deixar assolit ja que era quelcom que amb Ramon Martí Alsina no s'havia fet fins ara. <br/>És de tots conegut que Ramon Martí Alsina sempre s'ha considerat com un dels gran renovadors de la pintura catalana, l'home que va recuperar una manera de crear aliena a les exigències acadèmiques com a professor compromès, i que des d'aquesta posició va desenvolupar una pedagogia pròpia amb la que va crear escola, a més de ser una de les figures que més i millor van col·laborar en la recuperació cultural de Catalunya. Però malgrat tot, encara no havia estat objecte de cap tesi doctoral. Sí havia estat objecte de nombrosos articles en revistes artístiques i apareix en totes les publicacions de caràcter general de pintura catalana, i la monografia que li va dedicar Joaquim Folch i Torres l'any 1920 era fins el moment l'eina bibliogràfica de referència per abordar el personatge. Però feia falta més, i aquest ha estat el nostre objectiu. <br/>Així doncs, per la complexitat que implicava l'estudi del pintor vam estructurar el treball en tres volums. <br/>El primer consta d'una primera part que engloba tot el recorregut biogràfic revisat amb les noves aportacions que hem extret d'una part de l'arxiu familiar que els descendents del pintor han posat a la nostra disposició. En aquesta part fem una immersió profunda de la seva personalitat, de la seva vida, la seva família, els viatges, les exposicions i les crítiques de l'època, el seu compromís amb la ciutat a nivell social, artístic i polític, una visió íntima dels seus pensament i de la seva lluita. Per il·lustrar aquesta part hem utilitzat algunes cites recollides directament de les seves notes manuscrites, que presentem íntegrament transcrites a l'apèndix documental, en el tercer volum. <br/>La segona part d'aquest primer volum vol ser un recorregut artístic cronològic des de la crítica, és a dir, com la seva vida queda manifestada en la seva obra a través de l'estil progressiu, el tractament dels gèneres, anàlisi i comentaris de les obres més importants, les exposicions i les influències rebudes que hem pogut establir fent alguna comparació amb artistes de la seva època, sobretot amb França, amb la voluntat d'entendre una mica millor la seva trajectòria. <br/>Aquesta part del recorregut crític de la seva obra va íntimament relacionada amb el segon volum que vol ser una aproximació al catàleg del pintor, i diem aproximació perquè no tenim la intenció de convertir aquesta tesi en un catàleg tancat, sinó en un recull aproximatiu de les millors obres que hem pogut aconseguir fins el moment, i moltes més prou conegudes. L'obra de Ramon Martí Alsina és immensa, i gairebé com a conseqüència, molt irregular, per la qual cosa, vam pensar que era una mica incoherent plantejar-nos un catàleg tancat. És per tant que el catàleg de Martí Alsina quedarà obert per futurs estudis més exhaustius. <br/>L'últim volum recull tot un apèndix on es presenta de manera inèdita la transcripció de la part de l'arxiu familiar que hem tingut el privilegi de consultar i estudiar. A banda de la novetat documental innegable que aporten aquests escrits, s'afegeix el fet del descobriment de Martí Alsina com a escriptor i poeta, facetes gens conegudes fins ara i que, realment, deixen al descobert la seva idiosincràsia com a persona i artista. També s'inclou documentació molt més concreta d'aspectes administratius o afins a la seva persona que hem pogut anar trobant al llarg d'aquesta investigació.<br>The main structure of this work is based on the classical proposals of the artist's life and work. This was the first step to reach because it had not been made before with Ramon Marí Alsina. <br/>Martí Alsina has always been considered one of the great reformers of the Catalan painting, the one who recovered the way to create without following the academic requirements as a committed teacher. From this position he developed his own pedagogy, creating a new school. <br/>He also was one of the most important figures involved in the collaboration with the cultural recuperation of Catalonia, but he had not been object of any doctoral thesis. <br/>Martí Alsina had been object of numerous articles in artistic magazines and he also appears in all Catalan painting publications of general interest. Matrí Alsina's biography, written by Joaquim Folch i Torres in 1920, has been the reference book to approach and study him. But it was necessary to go further, and this became our aim. <br/>Due to the complexity of studying the painter we structured the thesis in three volumes. <br/>The first contains a biographical itinerary revised with the new contributions we have extracted from a part of the family archive that the painter's descendants have put at our disposal. In this part we make a deep immersion in his personality, his life, his family, the journeys, the exhibitions and the critics of the period. We also focus on his social commitment with the city, in both artistic and political aspects, on his intimate vision of his thought and fight. To illustrate this first part we have picked up some quotes directly from his handwritten notes, which we completely transcribed in the documental appendix of the third volume. <br/>The second part of this first volume wants to be a chronological artistic itinerary from the criticism, how his life comes off manifested in his work through the progressive style, the treatment of the genres, analysis and comments of the most important works, the exhibitions and the influences that we have been able to establish making some comparisons with other artists of his period, especially from France. <br/>The second volume is an approach to the painter's catalogue, and we propose the word "approach" because we do not intend to convert this thesis into a complete catalogue, but into an approximate collection of the best works that we have been able to study including some pieces well known. <br/>The last volume is an appendix where we present the transcription of a part of the family's unedited archive, documentation that we have had the privilege of consulting and studying. These writings bring us the possibility to discover Martí Alsina as a writer and poet, aspects unknown until now and that they really show us his idiosyncrasy as a person and artist. We also include administrative and personal documentation that we have been able to find along this research.

La technologie de reprogrammation de cellules somatiques en cellules souches pluripotentes induites (iPS) offre aujourd’hui l’opportunité de modéliser des maladies neurodégénératives et d’étudier des neurones de patients. Nous avons utilisé cette technologie pour générer deux modèles de maladies neurodégénératives : la mucopolysaccharidose de type IIIB (MPSIIIB) et la forme ALS2 de la sclérose latérale amyotrophique (SLA). Dans le modèle MPSIIIB, nous avons montré que les iPS et les neurones de patients présentaient des défauts caractéristiques de la pathologie telle que l’accumulation de vésicules de surcharge. Des altérations de l’appareil de Golgi dans ces cellules ont également été mises en évidence. Une analyse du transcriptome de précurseurs neuraux MPSIIIB a montré des modifications transcriptionnelles touchant notamment des gènes impliqués dans les interactions de la cellule avec la matrice extracellulaire. Ainsi, dans une seconde étude, des altérations de la migration et de l’orientation de cellules de souris mutantes MPSIIIB ou de patients ont été démontrées. Ces altérations pourraient être responsables des perturbations de la neurogénèse et de la neuritogénèse chez les enfants malades. Dans le modèle SLA/ALS2, nous avons montré que les neurones de patients présentaient des défauts incluant une diminution de la surface des endosomes et des anomalies de la croissance neuritique. Alors qu’il n’existait jusqu’alors aucun modèle cellulaire pertinent reproduisant cette maladie, ce modèle permettra à présent d’étudier les processus physiopathologiques impliqués dans la maladie. En conclusion, la génération de cellules iPS permet de modéliser des maladies neurodégénératives et d’étudier les processus physiopathologiques qui sont associés sur des neurones humains en culture. Ces modèles cellulaires pourraient permettre dans un avenir proche de réaliser des criblages de molécules à visée thérapeutique<br>Reprogramming technology of somatic cells in induced pluripotent stem cells (iPS) now offers the opportunity to model neurodegenerative diseases and to study patient’s neurons. We used this technology for generating two models of neurodegenerative diseases: the muccopolysaccharidosis type IIIB (MPSIIIB) and the ALS2 form of amyotrophic lateral sclerosis (ALS). In the MPSIIIB model, we have shown that iPS and neurons of patients had characteristic defects of the disease such as the accumulation of storage vesicles. Alterations of the Golgi apparatus in these cells were also highlighted. Transcriptome analysis of MPSIIIB neural precursors showed transcriptional changes involving particularly genes implicated in cell-extracellular matrix interactions. Thus, in a subsequent study, alterations of migration and orientation of MPSIIIB mutant mouse cells and MPSIIIB patients’ cells have been demonstrated. These alterations may be responsible for the disruption of neurogenesis and neuritogenesis in sick children. In the ALS2 model, we have shown that patients’ neurons had defects including decreased endosomes’ surface and abnormal neurite outgrowth. As there was previously no relevant cellular model reproducing the disease, this model will now allow the study of physiopathological processes involved in the disease. In conclusion, the generation of iPS cells allows to model neurodegenerative diseases and to study associated physiopathological processes on cultured human neurons. These cell models could allow in the near future the screening of molecules of potential therapeutical interest

El objetivo principal de este trabajo es abordar, desde diversos ángulos de análisis, las maneras en que una persona puede utilizar las herramientas del Derecho. Si tuviésemos que definir el problema o el conjunto de problemas planteados a lo largo de los ocho capítulos que siguen, la respuesta sería cómo vive la gente el Derecho y sus propios derechos. Tomamos como objeto de estudio a un personaje típico del mundo colonial americano, un piloto llegado a Buenos Aires a mediados del siglo XVIII aprovechando el ascenso económico del puerto, y que se convirtió rápidamente en uno de los comerciantes más prósperos. Jaime Alsina i Verjés fue, para la vida jurisdiccional de la ciudad de Buenos Aires, uno de sus ´vecinos legales´ más importantes.<br>The main objective of this work is addressed, from different angles of analysis, the ways that a person can use the tools of law. If we were to define the problem or set of problems along the eight chapters, the answer would be how people live the law and their rights. We take as a case study of a typical character of American colonial world, a pilot come to Buenos Aires in the mid-eighteenth century, using the economic rise of the port, and quickly became one of the most prosperous merchants. Jaime Alsina i Verjés was for the court life of the city of Buenos Aires, one of its most important ''vecinos legales”.

This chapter extends the s-structure analysis of Deictic SVCs in Barayin to semantically similar constructions in Choctaw (Broadwell 2000) and Wambaya (Nordlinger 2010). Both languages have morphemes expressing directionality or associated motion that combine with a verb as a co-predicate. Previous LFG analyses have treated these as cases of predicate composition based on work of Alsina (1993) and Butt (1995), and both have used Lexical Conceptual Structures (Jackendoff 1990) to model the semantic composition. In this chapter, the constructions are reanalyzed as cases of argument sharing in a connected s-structure. The semantics of the Choctaw motion co-predicates suggests an alternate conceptualization of motion meaning in s-structure, and this alternate view is applied to Barayin and Wambaya.

Researchers have posited different types of engagement, distinguishing between behavioral, cognitive, and affective engagement and theoretical frameworks have helped explain the psychological aspects of engagement. However, game researchers should examine all types of engagement using multiple methodologies as a means to understand what students are learning from educational games during game play. Conclusive results require psychological aspects and learning characteristics to be considered, but also require a deeper understanding of the intricate links between learning and game mechanics for engagement. This article presents the findings from a qualitative study with thirty participants that focuses on the importance of affective and cognitive engagement during game play with educational games. To do this, the researchers used Ferran Alsina, a game that would help to develop learning competences of primary education skills. Researchers obtained the experiences of students through a game play session, basic game metrics, think-aloud protocol, observation and focus groups. Results shows that the game provided participants an active participation associated with both affective and cognitive engagement. Without attention to cognition the atuhors risk losing valuable data that relate to a student's learning. Researchers should consider multiple qualitative methodologies and game play experience analysis as student experiences are qualitative.

The aim of this study is to conduct a bibliometric analysis of articles related to environmental education in early childhood (EEEC). The sub-objectives of the study were to determine the distribution of studies on EEEC by years, the most used keywords, the most cited articles, the most active researchers, the most cited journals and the most active collaborating countries. Bibliometric analysis methods were used in the research. Bibliometric mapping analysis was preferred to provide visual representations of the relationships between the main concepts. The data were obtained from the Web of Science (WoS) database and the 191 articles accessed because of filtering were analysed using VOSviewer software. As a result of the research, it was determined that studies on EEEC have increased over the years. Among the keywords, “early childhood education”, “environmental education” and “sustainability” came to the fore respectively. The most cited study was “Beyond Stewardship: Common World Pedagogies for the Anthropocene”. Prominent journals included “Australian Journal of Environmental Education” and “Sustainability”, while the most influential authors were identified as “Alsina, A.” and “Rodrigues-Silva, J.”. Among the countries, “Australia”, “Canada” and “Brazil” are at the forefront. Encouraging more co-operation and interdisciplinary studies in the field of EEEC will help deepen research in this field.
