APPRENDENTI UCRAINI DI ITALIANO L2 IN PROGETTI DI ACCOGLIENZA: CASE-STUDY
No full textIl presente contributo presenta uno studio di caso nell’ambito dell’insegnamento/ apprendimento dell’italiano presso un gruppo di discenti di origine ucraina rifugiati in Italia. Si presentano alcuni dati di contesto che descrivono l’immigrazione ucraina in Italia, pre e post emergenza, la situazione linguistica nel Paese di origine, le specificità dell’apprendente adulto e i contesti di accoglienza in cui si è svolta la ricerca. La ricerca, di tipo qualitativo, ha visto la somministrazione di due questionari: uno dedicato agli studenti e l’altro ai relativi docenti con quesiti sulle modalità glottodidattiche messe in atto, il loro apprezzamento e la valutazione dell’efficacia percepita. Nel contributo, dopo la descrizione delle rispettive survey, si riportano e analizzano i dati raccolti contestualizzandoli. In fase finale si provano a fornire a docenti suggerimenti e pratiche operative adatte ad immigrati adulti ucraini per un apprendimento proficuo della lingua italiana.
Ukrainian learners of Italian L2 in reception projects: case-study
This contribution presents a case study in the field of teaching/learning Italian language among a group of learners who are refugees of Ukrainian origin living in Italy. Contextual data are presented which describes Ukrainian immigration to Italy, pre and post emergency, the linguistic situation in the country of origin, the specificities of the adult learner and the reception contexts in which the research was carried out. The qualitative research saw the administration of two questionnaires: one dedicated to the students and the other to the relative teachers with questions on the language teaching methods implemented, their appreciation and the evaluation of the perceived effectiveness. In the contribution, after the description of the respective surveys, the collected data are reported and analyzed by contextualizing them. In the final phase they try to provide teachers with suggestions and operational practices suitable for adult Ukrainian immigrants for a productive Italian language learning experience
A computational framework to explore optimality in human movement
No full textPredictive model-based simulations of system dynamics are powerful tools to explore optimality criteria underlying human movement (e.g. walking). This field of research is raising interest from the biomechanics and robotics communities, as predictive approaches can provide new insights in many areas, such as in the design and control of robotic assistive devices
Identification of Motor Control Objectives in Human Locomotion via Multi-Objective Inverse Optimal Control
No full textPredictive simulations of human motion are a precious resource for a deeper understanding of the motor control policies encoded by the central nervous system. They also have profound implications for the design and control of assistive and rehabilitation devices, for ergonomics, as well as for surgical planning. However, the potential of state-of-the-art predictive approaches is not fully realized yet, making it difficult to draw convincing conclusions about the actual optimality principles underlying human walking. In the present study we propose a novel formulation of a bilevel, inverse optimal control strategy based on a full-body three-dimensional neuromusculoskeletal model. In the lower level, prediction of walking is formulated as a principled multi-objective optimal control problem based on a weighted Chebyshev metric, whereas the contributions of candidate control objectives are systematically and efficiently identified in the upper level. Our framework has proved to be effective in determining the contributions of the selected objectives and in reproducing salient features of human locomotion. Nonetheless, some deviations from the experimental kinematic and kinetic trajectories have emerged, suggesting directions for future research. The proposed framework can serve as an inverse optimal control platform for testing multiple optimality criteria, with the ultimate goal of learning the control objectives that best explain observed human motion
“Second Language Teaching with Refugees: Educational Experiences and Welcoming Environments”
No full textThis qualitative research aims to gain a deeper understanding of the relationship between previous schooling experiences and second language learning among a group of adult refugees and asylum seekers. Refugees and asylum seekers present unique challenges to educators in host countries. Issues related to forced migration, low literacy levels, cultural estrangement are among the many challenges encountered (Shapiro et al., 2019). These multiple small case studies were conducted at a school in Northern Italy. The paper examines the refugees' educational histories and explores how humanizing teaching practices can facilitate both teaching and learning (Freire, 1970/2018; Pasquarella et al., 2022). Through one-on-one interviews and a focus group, the authors found that the refugees’ educational backgrounds were markedly different. The analysis reveals that previous schooling experiences and challenging living conditions shaped the refugees' attitudes toward education. Despite these challenges, participants affirmed that the humanistic approach adopted by the teachers was effective in alleviating the anxieties and fears about language learning of many refugees, helping to bridge an important gap in language teaching across cultures
Kinematic analysis of the Lolotte technique in rock climbing
No full textThe lolotte or drop-knee technique is a fundamental of rock climbing that particularly involves lower limbs, and especially knee joints. To the authors' best knowledge, no biomechanical analysis of the lolotte seems to have ever been conducted, despite its widespread use. As a first contribution to this research topic, the present work deals with an athlete-specific kinematic analysis of the lolotte aimed at quantifying the hip and knee joint angle trajectories and knee ligament strains. A marker-based motion capture system was employed to track the execution of the lolotte on a purposely designed climbing structure. The marker trajectories were then used as input for a numerical simulation in the OpenSim program, where an athlete-specific musculoskeletal model was set up to perform an inverse kinematics analysis and obtain the joint angle trajectories as well as their ranges of motion. Further processing of the model allowed to estimate the strain of the knee medial collateral ligament. Such kinematic analysis revealed characteristic hip and knee joint angle patterns and highlighted a critical phase in which the knee is considerably abducted (increased valgus). As a consequence, the medial collateral ligament is remarkably recruited, thereby substantiating the claim diffused among climbers that drop-kneeing may cause ligament injury
On the estimation of hip joint loads through musculoskeletal modeling
No full textNoninvasive estimation of joint loads is still an open challenge in biomechanics. Although musculoskeletal modeling represents a solid resource, multiple improvements are still necessary to obtain accurate predictions of joint loads and to translate such potential into practical utility. The present study, focused on the hip joint, is aimed at reviewing the state-of-the-art literature on the estimation of hip joint reaction forces through musculoskeletal modeling. Our literature inspection, based on well-defined selection criteria, returned seventeen works, which were compared in terms of methods and results. Deviations between predicted and in vivo measured hip joint loads, taken from the OrthoLoad database, were assessed through quantitative deviation indices. Despite the numerous modeling and computational improvements made over the last two decades, predicted hip joint loads still deviate from their experimental counterparts and typically overestimate them. Several critical aspects have emerged that affect muscle force estimation, hence joint loads. Among them, the physical fidelity of the musculoskeletal model, with its parameters and geometry, plays a crucial role. Also, predicted joint loads are markedly affected by the selected muscle recruitment strategy, which reflects the underlying motor control policy. Practical guidelines for researchers interested in noninvasive estimation of hip joint loads are also provided
Primi tentativi di figurazione: l'inizio dell'arte nelle lezioni berlinesi di Hegel
No full textThe object of the present study is Hegel’s conception of the symbolic form of art, as it is described in Hegel’s Lectures on the Philosophy of Art. I will focus on the problem of the symbolic form of art in order to highlight its essential traits and to define the role it plays in the development of art.
Hegel gave a series of lectures on the philosophy of art in several university terms (in 1820/21, 1823, 1826 and 1828/29), but never published a book of his own on this topic. In order to highlight the peculiarities of Hegel’s mature conception of symbolic art, I will read transcripts of Hegel's lectures made by his students, the §§ 556–63 of the Encyclopaedia (1830) and some Hegel’s reviews published by him on magazines. In order to point out the development of Hegel's conception of symbol and symbolic art, I will also contemplate the notions of art and symbol in some texts dated from his period in Jena, Nürnberg and Heidelberg.
The first chapter is devoted to recreate the specific background in which Hegel develops his conception of art. More specifically, I will offer a terminological and historic-philosophical analysis of the concepts of art and symbol, which characterize Germany during the early years of the 19th century.
The second chapter is dedicated to the concept of symbol. In this chapter I will first analyze the concept of symbol which Hegel presents in the Encyclopaedia’s section devoted to the Psychology. Then I will focus on the properties that Hegel confers to the symbol in his lectures on the philosophy of art and I will try to highlight the complexity of this concept.
In the third chapter, I will deal with the issue of the end of the symbolic art: does the symbolic art end before or after the classical art? In order to answer to this question, I will compare the creation, the contents and the fruition of the classical form of art with the creation, the contents and the fruition of the symbolic form of art. I will also try to show that Hegel doesn’t define the classical beauty as the reconciliation of figure and content.
In the last chapter I will consider the connection between Hegel’s concept of symbolic art and the human ability to break with the habits and with what is already known, and to become open to something new.
