Master Thesis on Friday Sep 23, 2022 at 09:00 Place: IFISC Seminar Room Title: Modeling preferences in language contact Speaker: Pablo Rosillo, IFISC Abstract: <div> <div> <div> <div> <div> <div> <p><span style="font-family:'Calibri'; font-size:12.000000pt">Since the publication of the pioneering work on language contact by Abrams and Strogatz in 2003, different models based on quantitative dynamical approaches have been developed to try to gain more insight in the forces that lead to the coexistence or extinction of languages. These phenomena are also observed in varieties of major languages. In this work we present a model that takes into account sociological factors to describe contact of different varieties of a same language. Our model considers both a fixed prestige hierarchy and the effect of the preferences of the speakers. Importantly, we find that preferences determine the fate of the different varieties, often independently of their prestige. </span></p> <p>https://us06web.zoom.us/j/87822578801?pwd=VTdqT25GTkQxeGRLb3FHandmcFNjdz09</p> <p>Supervisors: David Sanchez and Maxi San Miguel</p> <p>Further jury members: Jose J.

Master Thesis on Thursday Sep 22, 2022 at 14:30 Place: Zoom Seminar Title: CREATIVITY AS A RANDOM WALK SEARCH ON A SEMANTIC NETWORK Speaker: Nicoleta Kyosovska, IFISC Abstract: <p>Creativity is a fascinating quality of our minds. It is an essential ingredient for innovation, creating beauty, or solving everyday problems. &rdquo;Little-C&rdquo; creativity is particularly indispensable in everyday cognitive functioning, yet research still hasn&rsquo;t come up with a full account of the psychological and neurobiological mechanisms underpinning it. Since it is multi-faceted and is, by definition, a very high-level process, it is a challenge to create a model which encompasses all stages of the creative process and unifies all its low-level mechanisms.<br /> In this work, we focus on studying creative thinking under the associative theory of creativity. We do so by using a simple dynamical model for undirected search. We evaluate it on a widely-used test for creativity. We want to see whether a simple local search process on a network can lead to finding the solution to a multiply-constrained problem. By using an open-ended process on a closed-solution task we attempt to achieve a unification of the distinct aspects of creative ability.</p> <p>Supervisors: Ra&uacute;l Vicente, V&iacute;ctor Egui&iacute;luz</p> <p>Tutor: Claudio Mirasso</p> <p>Jury:<br /> David S&aacute;nchez</p> <p>Lucas Lacasa</p> <p>Claudio Mirasso</p> <p>zoom link:&nbsp;<span style="font-size:large"><span style="font-family:Book Antiqua"><a class="moz-txt-link-freetext" href="https://uibuniversitat.zoom.us/j/92448886619">https://uibuniversitat.zoom.us/j/92448886619</a></span></span></p> <p>&nbsp;</p> Url event:https://ifisc.uib-csic.es/en/events/seminars/creativity-as-a-random-walk-search-on-a-semantic-n/

IFISC Seminar on Wednesday Sep 21, 2022 at 14:30 Place: IFISC Seminar Room Title: The Knowledge Acquisition process from a Complex System perspective Speaker: Fátima Velásquez-Rojas, IFISC Abstract: <p>The process of acquiring knowledge is one of the most complex for the human being since it involves individual and social processes that have been studied by various epistemological currents. The educational context where this process is developed is of great relevance since it represents the meeting space between teachers and students, in which a fundamental part of the construction of new knowledge occurs. On this occasion, I will share the results of the works published during the time I was working in this area, which, although it has been little explored from complex systems, offers a phenomenological richness that is not indifferent to us. We will start by proposing the modeling of the knowledge acquisition process in a known regular educational context and then move on to how this process was affected during the COVID-19 pandemic. These works shed light on the internal dynamics of the classroom and allow us to understand some global aspects of the teaching-learning process.</p> <p>Presential seminar, with parallel Zoom stream:&nbsp;&nbsp;https://zoom.us/j/98286706234?pwd=bm1JUFVYcTJkaVl1VU55L0FiWDRIUT09</p> Url event:https://ifisc.uib-csic.es/en/events/seminars/the-knowledge-acquisition-process-from-a-complex-s/

Talk on Tuesday Sep 20, 2022 at 12:00 Place: IFISC Seminar Room Title: New simple model for pattern formation in coral reefs Speaker: Miguel Álvarez-Alegría, IFISC Abstract: <p>Coral reefs are one of the most fascinating ecosystems in the world. Even without considering interactions with the whole reef wildlife, corals biology is plenty of complex phenomena such as the symbiosis with microalgae and emergent properties such as synchronized sexual events under very specific conditions. Many coral species self-organize&nbsp;into well defined structures such as: massive, branching and table coral colonies.&nbsp;Colonies living in the same region constitute a reef. Various coral species synthesize aragonite (a phase of calcium carbonate) during their clonal growth to build themselves a hard exoskeleton. When an entire colony dies, another new coral polyp can settle over the hard structure left behind by the dead colony and start a new colony on top of these remains. This process is repeated over centuries leading to the formation of large aragonite structures which display some recognizable patterns that can be spotted around the world. These include closed atolls and parallel stripes, together with large groups of closed atolls and little halos inside these big atolls (an example of self-similarity in this system).</p> <p><br /> In this work, we address the study of pattern formation in coral reefs by proposing a set of differential equations that govern the spatiotemporal evolution of some variables describing the system, taking into account corals ecology and the&nbsp;key role of hydrodynamics in reef shaping.</p> Url event:https://ifisc.uib-csic.es/en/events/seminars/new-simple-model-for-pattern-formation-in-coral-re/
