The link between vulnerability and social exclusion and criminal trajectories. An association study
2017
Este estudio tiene por objeto identificar la relación existente entre las trayectorias delictivas y los factores de vulnerabilidad y exclusión social en adolescentes en conflicto con la ley. Para ello se analizan 281 expedientes de adolescentes en conflicto con la ley de la ciudad de València y se generan 3 trayectorias delictivas: inicial, moderada y consolidada, que se asocian a indicadores de vulnerabilidad y exclusión social. Se muestran evidencias empíricas de su relación. Las trayectorias delictivas y los factores de vulnerabilidad y exclusión social se hallan plenamente conectados, entrelazados y superpuestos. La acumulación de factores de vulnerabilidad y exclusión social en adolesc…
Event-Based Trajectory Prediction Using Spiking Neural Networks
2021
International audience; In recent years, event-based sensors have been combined with spiking neural networks (SNNs) to create a new generation of bio-inspired artificial vision systems. These systems can process spatio-temporal data in real time, and are highly energy efficient. In this study, we used a new hybrid event-based camera in conjunction with a multi-layer spiking neural network trained with a spike-timing-dependent plasticity learning rule. We showed that neurons learn from repeated and correlated spatio-temporal patterns in an unsupervised way and become selective to motion features, such as direction and speed. This motion selectivity can then be used to predict ball trajectory…
Becoming a multilingual health professional in vocational education - two adult migrants’ translanguaging trajectories
2022
The number of migrant students in vocational education in Finland is rising. Their educational backgrounds and language resources are diverse, and research is needed to gain better understanding on how their existing knowledge can be acknowledged, supported, and deployed when they become multilingual professionals in their own fields. In this ethnographic study, we drew on the theoretical approaches of translanguaging and language architecture (García, O., and T.Kleyn. 2016. “Translanguaging Theory in Education.” In Translanguaging with Multilingual Students: Learning from Classroom Moments, edited by O. García, and T. Kleyn, 9–33. New York, London: Routledge; Li, Wei. 2018. “Translanguagin…
Career intentions of Australian physical education teachers
2015
The purpose of this study was to investigate Australian physical education (PE) teachers’ career intentions and factors influencing their intentions. A sample (N = 234) of Western Australian PE teachers responded to a questionnaire determining PE teachers’ work and the primary motivators for intention to leave the profession. Half (51.3%) of the respondents wanted a change from their current PE teacher job and 39.8% were intending to leave PE teaching. The most frequent reasons for wanting to leave PE related to: non-use of expertise, workload, school administration, and lack of opportunities for personal and professional development. Consideration should be given to mediation strategies th…

Optimal control of the Schrödinger equation with two or three levels
2007
In this paper, we present how techniques of “control theory”, “sub-Riemannian geometry” and “singular Riemannian geometry” can be applied to some classical problems of quantum mechanics and yield improvements to some previous results.
