Estimating on the fly: The approximate number system in rufous hummingbirds (Selasphorus rufus)
Authors: Corliss Mia , Brown Theo , Hurly T. Andrew , Healy Susan D. , Tello-Ramos Maria C. 
Published: December 2020

AbstractWhen presented with resources that differ in quantity, many animals use a numerosity system to discriminate between them. One taxonomically widespread system is the approximate number system. This is a numerosity system that allows the rapid evaluation of the number of objects in a group and which is regulated by Weber’s Law. Here we investigated whether wild, free-living rufous hummingbirds (Selasphorus rufus) possess an approximate number system. The hummingbirds were presented with two experiments. In the first we investigated whether hummingbirds spontaneously chose an array containing more flowers than an alternate array. In the second we asked whether the hummingbirds could learn to use numerosity as a cue to which of two arrays contained the better reward. The birds did not spontaneously prefer an array containing more flowers. After minimal training, however, they learned to choose the more numerous array and could differentiate between arrays of five and seven flowers. These data support the presence of an approximate number system in the rufous hummingbird. It seems plausible that having such a system would enable much more efficient foraging in this species.
Taking the perspectives of many people: Humanization matters
Authors: Ye Tian , Furumi Fumikazu , Catarino da Silva Daniel , Hamilton Antonia 
Published: December 2020

AbstractIn a busy space, people encounter many other people with different viewpoints, but classic studies of perspective-taking examine only one agent at a time. This paper explores the issue of selectivity in visual perspective-taking (VPT) when different people are available to interact with. We consider the hypothesis that humanization impacts on VPT in four studies using virtual reality methods. Experiments 1 and 2 use the director task to show that for more humanized agents (an in-group member or a virtual human agent), participants were more likely to use VPT to achieve lower error rate. Experiments 3 and 4 used a two-agent social mental rotation task to show that participants are faster and more accurate to recognize items which are oriented towards a more humanized agent (an in-group member or a naturally moving agent). All results support the claim that humanization alters the propensity to engage in VPT in rich social contexts.
Helioseismic Finite-frequency Sensitivity Kernels for Flows in Spherical Geometry including Systematic Effects
Authors: Bhattacharya Jishnu 
Published: December 2020

Abstract
Helioseismic inferences of large-scale flows in the solar interior necessitate accounting for the curvature of the Sun, both in interpreting systematic trends introduced in measurements as well as the sensitivity kernel that relates photospheric measurements to subsurface flow velocities. Additionally, the inverse problem that relates measurements to model parameters needs to be well posed to obtain accurate inferences, which necessitates a sparse set of parameters. Further, the sensitivity functions need to be computationally easy to evaluate. In this work, we address these issues by demonstrating that the sensitivity kernels for flow velocities may be computed efficiently on the basis of vector spherical harmonics. We are also able to account for line-of-sight projections in Doppler measurements, as well as center-to-limb differences in line-formation heights. We show that given the assumed spherical symmetry of the background model, it is often cheap to simultaneously compute the kernels for pairs of observation points that are related by a rotation. Such an approach is therefore particularly well suited to inverse problems for large-scale flows in the Sun, such as meridional circulation.

Gaia Pulsars and Where to Find Them in EDR3
Authors: Antoniadis John 
Published: December 2020

Abstract
The Early Gaia Data Release 3 (EDR3) provides precise astrometry for nearly 1.5 billion sources across the entire sky. A few tens of these are associated with neutron stars in the Milky Way and Magellanic Clouds. Here, we report on a search for EDR3 counterparts to known rotation-powered pulsars using the method outlined in Antoniadis. A cross-correlation between EDR3 and the ATNF pulsar catalog identifies 41 close astrometric pairs (≲05 at the reference epoch of the pulsar position). Twenty six of these are related to previously known optical counterparts, while the rest are candidate pairs that require further follow-up. Highlights include the Crab Pulsar (PSR B0531+21), for which EDR3 yields a distance of

Gravitational Instability of a Magnetic Rotating Disk with Ohmic Dissipation and Ambipolar Diffusion
Authors: Das Indrani , Basu Shantanu 
Published: December 2020

Abstract
We perform a linear analysis of the stability of isothermal, rotating, magnetic, self-gravitating sheets that are weakly ionized. We include a self-consistent treatment of thermal pressure, gravitational, rotational, and magnetic (pressure and tension) forces together with two nonideal magnetohydrodynamic (MHD) effects: Ohmic dissipation and ambipolar diffusion. Our results show that there is always a preferred lengthscale and associated minimum timescale for gravitational instability. The addition of rotation leads to a generalized Toomre criterion (that includes a magnetic dependence) and modified lengthscales and timescales for collapse. We show that both the nonideal MHD effects qualitatively behave in a similar way but have quantitative differences. We apply our results to protostellar disk properties in the early embedded phase and find that the preferred scale of instability can significantly exceed the thermal (Jeans) scale and the peak preferred fragmentation mass is likely to be ∼10–90M

Migración, racismo y humor. Estereotipos sobre el migrante andino en las historietas del Perú oligárquico
Authors: Rodríguez Luis 
Published: December 2020

La tesis estudia cómo se reprodujeron y fortalecieron los estereotipos sobre el migrante andino en un contexto de masiva migración durante los años cincuenta en Lima. Para ello, proponemos a la historieta como un artefacto cultural que permite conocer los discursos racistas de la época. En ese sentido, hemos estudiado a la historieta durante sus primeros diez años de publicación que coincidieron con el Perú oligárquico, hemos resaltado —desde el concepto de la etnicidad— aquellas viñetas que manifiestan un estereotipo que tiene como base la deformación intencional de la cultura. Así, la caricatura Serrucho transmitió la percepción racista limeña y los estereotipos que le imponían al migrante andino, estos deformaban sus características culturales como las costumbres, gustos, hábitos, conducta y moral, lo que generó la creación de una imagen inamovible e inalterable de lo que se supone era un migrante.
Feminismos y sexualidad: Placer y peligro, versus libertad y censura. De los debates feministas (inacabados) de fin de siglo, a los de hoy
Authors: Almirón Mengíbar Ana 
Published: December 2020

El 11/09/2019 la Universidade da Coruña (UDC) suspende una jornada de debate sobre trabajo sexual al no poder garantizar su seguridad, dado el “fuerte rechazo, acoso y crueldad” recibidos, tras la polémica protagonizada por activistas abolicionistas bajo el hashtag #UniversidadSinProstitución, denunciando la iniciativa y afirmando que formaba parte de la estrategia del “lobby proxeneta”. Apenas un mes después, el 18/10/2019, 22 universidades de todo el estado hacen público un programa colectivo tratando de abrir un debate en libertad sobre trabajo sexual, bajo el hashtag #UniversidadSinCensura, que pudiera arrojar luz sobre ello, dando voz además, como algo fundamental, a las propias protagonistas. Debate en el que se inscribe este Monográfico. Un debate por tanto no solo académico, sino social y político, pero ni novedoso ni con un único punto de vista feminista al respecto, a lo largo de los casi cincuenta años de debates feministas de este país, desde sus inicios como movimiento social (años 70) hasta la actualidad, transitando entre el placer y el peligro hacia el reconocimiento de la diversidad y libertad sexual, contra la estigmatización, censura y prohibición de derechos. Debates feministas que hemos querido trasladar aquí, de forma obligatoriamente resumida, mostrando la pluralidad de ideas y propuestas, desde entonces hasta hoy, planteándonos finalmente cuales podrían ser los retos actuales del movimiento feminista, en un contexto de creciente conservadurismo estatal y global.

Authors: Oliveira Adailson Regis de 
Published: December 2020

O presente trabalho é resultante da pesquisa de dissertação em Sociologia no PPGS/UFPB em 2016. Teve por objetivo analisar a participação política de jovens que integram ou integraram a Rede de Jovens do Nordeste. Buscou discutir uma das formas de participação política da juventude que se expressa, sobretudo, pela articulação em redes e pela abertura para a atuação em organismos governamentais. A pesquisa, de natureza qualitativa, foi feita a partir de relatos de 11 colaboradores, sendo 6 (seis) homens e 5 (cinco) mulheres, no sentido de apreender como atribuem significado a suas experiências como atores políticos, sejam nas práticas organizativas e de mobilização sejam como representantes da Rede em organismos governamentais. O período analisado é de 2005 a 2011, quando a Rede é mais atuante no Nordeste, e foram entrevistados jovens que participaram em diferentes momentos da história da Rede. As análises das falas dialogam com o conceito de juventude, entendido como uma categoria mutável que é significada também pelos próprios jovens a partir de suas experiências na família, no trabalho, na escola, na igreja e na política. A participação política é entendida num sentido ampliado envolvendo práticas organizativas de ação direta e de mediação, bem como a elaboração de representações sobre o significado da democracia, da participação e da cidadania.
