Effects of a Motivational Climate on Psychological Needs Satisfaction, Motivation and Commitment in Teen Handball Players

The aim of this study was to examine the effects of the motivational climate created by the coach and perceived by a group of young high-performance handball players on their sport motivation, self-determination, sport psychological needs and sport commitment. The study participants were 479 young handball players. The age range was 16–17 years old. Players were administered a battery composed of a Perceived Motivational Climate in Sport Questionnaire, Sport Motivation Scale, the Basic Psychological Needs in Exercise Scale and Sport Commitment Questionnaire to measure the above-mentioned theoretical constructs. Results showed that the handball players showed high levels of a task-involving climate, of basic psychological needs satisfaction and of self-determined motivation and commitment. Higher levels of basic psychological needs such as autonomy and competence were associated with a higher task-involving climate, self-determined index and sport commitment (task-involving climate–basic psychological needs (β = 0.55; 95% IC 0.387/0.682; p = 0.001); Ego-involving climate–basic psychological needs (β = 0.06; 95% IC −0.069/0.181; p = 0.387); Basic psychological needs–self-determined index (β = 0.48; 95% IC 0.376/0.571; p = 0.001); Self-determined index–commitment (β = 0.58; 95% IC 0.488/0.663; p = 0.001). The obtained model showed that basic psychological needs mediated the association between a task-involving climate and self-determination, and self-determination mediated the association between basic psychological needs satisfaction and commitment

Motivational determinants of physical education grades and the intention to practice sport in the future

Self-Determination Theory (SDT) is amongst motivational frameworks the most popular and contemporary approach to human motivation, being applied in the last decades in several domains, including sport, exercise and physical education (PE). Additionally, Achievement Goal Theory (AGT) has presented evidence of how contextual factors may influence student's behavior in this particular context. The main purpose of this study was to analyze the motivational climate created by the teacher in the classroom, students' satisfaction of Basic Psychological Needs (BPN), and how their behavioral regulation could explain PE grades and intention to practice sports in the future.Funding: This project was supported by the National Funds through FCT – Portuguese Foundation for Science and Technology (UID/ DTP/04045/2013) – and the European Fund for Regional Development (FEDER) allocated by European Union through the COMPETE 2020 Programme (POCI-01-0145FEDER-006969) – Competitiveness and Internationalization (POCI).info:eu-repo/semantics/publishedVersio

Expositions

The first comprehensive introduction to the origins, aspirations, and evolution of live coding. Performative, improvised, on the fly: live coding is about how people interact with the world and each other via code. In the last few decades, live coding has emerged as a dynamic creative practice, gaining attention across cultural and technical fields—from music and the visual arts to computer science. Live Coding: A User's Manual is the first comprehensive introduction to the practice and a broader cultural commentary on the potential for live coding to open up deeper questions about contemporary cultural production and computational culture. This multiauthored book—by artists and musicians, software designers, and researchers—provides a practice-focused account of the origins, aspirations, and evolution of live coding, including expositions from a wide range of live coding practitioners. In a more conceptual register, the authors consider liveness, temporality, and knowledge in relation to live coding, alongside speculating on the practice's future forms

Isolation and identification of fungi associated with Esca in Vinho Verde region (RDVV): northwest Portugal

In the Portuguese Vinho Verde region (RDVV), during the last years the esca incidence is taking serious proportions. In this context, in the summers of 2004 and 2005 three vineyards were selected (two within the Monção subregion and one outside) in order to isolate associated Esca-fungi. Cordons were taken from 10 infected Alvarinho cultivar grapevines showing esca foliar symptomatology. Results confirm the occurrence of species P. chlamydospora and P. angustius in RDVV. They identify for the first time the species P. viticola and P. inflatipes, both is this wine region and in the Alvarinho grape variety. Results show that there are different strains within one fungus specie in the majority of the isolated species, and also that the closer the vineyards, the higher the similarity of the fungi strains.Fundação para a Ciência e a Tecnologia (FCT) - bolsa (SFRHD/BD/32159/2006

Anatomical Intelligence: Live coding as performative dissection

This article describes the method of ‘dissective’ live coding, as developed through the artistic-research project Anatomies of Intelligence. In this work we investigate how live coding can be used as an approach for performative explorations of a data corpus and a machine learning algorithm operating on this corpus. The artistic framework of this project collides early Enlightenment-era anatomical epistemologies with contemporary machine learning, creating a fertile space for novel, embodied artistic methods to emerge. We engage audiences in an immersive, live-coded experience where image and sound are driven by our dissective approach, revealing the underlying rhythms and structures of a machine learning algorithm running live on an artist-made dataset. To support these performances we have developed a custom browser-based software, the Networked Theatre, used for both hybrid in-person/online audiovisual performances. In this article we describe this work and reflect on our experience as performers and audience feedback, which suggests that our dissective method of live coding, based on examining ‘ready-made’ algorithms, offers a unique experiential entryway into the bodies of machine learning and data corpi

Programa de Intervención psicológica para la optimización del concepto de equipo (team building) en jóvenes futbolistas

This study aims to develop a team-building program, a multidimensional psychological intervention based on the principles of team building (TB) (Spink and Carron, 1993, Vicente, 1999), and assess whether it can foster the development of team satisfaction and cohesion. The participants were 20 young footballers from one team. The Cohesion and Satisfaction perception variables were accessed with the Portuguese version of the ASQp and GEQp. The results showed that after the TB intervention, social cohesion increased, task cohesion held steady and satisfaction associated with aspects that converged towards the goals decreased. In the follow-up phase, task cohesion was steady and social cohesion declined. In conclusion, a psychological intervention programme may be a catalyst of cohesion, team satisfaction and performance within the context of this group

Effects of Esca disease on leaf gas exchange of cv. Alvarinho in a vineyard of the Portuguese Vinho Verde region

Esca is a very complex disease that is usually noticed when the grapevine show external symptoms. However, the grapevines can be infected for a long period of time and rarely manifest the typical leaf symptoms. Moreover, little is know about the consequences of Esca on vineyard productivity. In Portugal, in Vinho Verde region, Alvarinho sub-region, most vineyards are infected with Esca. In this work we evaluate the impact of Esca on some physiological parameters of grapevines cv. Alvarinho.This preliminary work reveal the importance that these kind of physiological measurements can have in the valuation of the infected Esca grapevine physiological conditions. These results may be used as a pattern to predict the damage magnitude of Esca disease in grapevines.Fundação para a Ciência e a Tecnologia (FCT)Fundação Luso-American

Choreographies of the Circle & Other Geometries

Choreographies of the Circle & Other Geometries, in Critical Coding Cookbook: Intersectional Feminist Approaches to Teaching and Learning. In the context of modern computer programming, the origin tale of code often begins with the Difference Engine and the Analytical Engine invented by Charles Babbage in 19th century Europe. This beginning, buoyed by the industrial revolution and militarization, fostered an embedded set of values into computation aligned with an ideology of standardization, optimization, and flawlessness. “Good” code is efficient code that operates on a scarcity mindset, limited by hardware and energy resources. And yet, there are histories to math, engineering, and computing that are less prominently recognized because they do not neatly fit into the narratives of capitalist production. Ada Lovelace and her contribution to the development of modern computing has only recently been more broadly recognized. Textile production, which led to the invention of the Jacquard Loom, was a great inspiration to Charles Babbage’s research. Gendered and racialized preconceptions greatly impact what is validated as technical and creative work. We believe that it is time to confront how computational history has been retrofitted to tell a single narrative by recentering marginalized ways of knowing. For example, one may trace back to poe divination to gain a new perspective on the boolean variables. Quipu may be seen as one of the oldest examples of data storage. Fractals, which are often reduced to mathematical formulas in computer science classrooms can be traced back to multiple beginnings throughout ancient history such as traditional African architecture. The Critical Coding Cookbook perceives history as a messy entanglement rather than a linear graph. There is a growing awareness towards reclaiming ancestral knowledge and a movement to decolonize computation. Through centering marginalized bodies and identities, we aim to build a collection of alternative histories, narratives, and approaches to computation. This volume of material can serve as an open-source educational resource across a spectrum of learning communities

A Trans-Disciplinary Tool for Collaborative, Choreographed, and Embodied Audio-Visual Live Coding

Seeking balanced and mutual interaction, the authors designed and implemented tools to connect a live coding system for audio built in Haskell with Javascript tools for live coding browser-based visuals to enable a collaborative audio-visual performance. Each system generates and emits OSC messages through functions developed by the authors and triggered by preexisting functions in those systems. The systems also gained subsystems for receiving incoming messages and modifying system state according to those messages. Means for displaying transmitted data were also implemented, allowing audiences greater insight into performer interactions. The system was designed to enhance the possibility of equal dialogue between the performers and avoid disastrous changes to a partner’s system state. It was developed following an on-going research and recollection of musical and choreographic scores that reference principles of non-linear composition, non-hegemonic time and space constructs, and techno-feminist perspectives
