Interview with Joan Pinkvoss and Nancy R. Barcelo
No full textTwo-part recorded testimonial about the work of Gloria Anzaldua and how it has impacted Joan Pinkvoss and Nancy Rusty Barcelo.
Joan Pinkvoss co-founded Aunt Lute Books (San Francisco, CA) in 1982, a nonprofit, multicultural press committed to publishing women writers whose voices and visions are underrepresented in mainstream presses by race, ethnicity, sexuality, socio-economic background, and or age. Aunt Lute has published such acclaimed authors as Alice Walker, Audre Lorde, and Gloria Anzaldúa.
Nancy “Rusty” Barceló is the former president of Northern New Mexico College; she is a leading figure with the National Initiative for Women in Higher Education (NIWHE) and has chaired Mujeres Activas en Letras y Cambio Social (MALCS) as well as the Washington State Native American Advisory Board (NAAB). In 2004, Barceló was awarded the Ohtli Award, which is a special recognition presented by the Mexican government to Mexicans or Latinos whose work has benefited Mexicans living abroad.https://scholarworks.utrgv.edu/gloriaanzalduatestimonios/1007/thumbnail.jp
Refringence, field theory, and normal modes
No full textIn a previous paper [Barcelo C et al 2001 Class. Quantum Grav. 18 3595610 (Preprint gr-qc/0104001)] we have shown that the occurrence of curved spacetime 'effective Lorentzian geometries' is a generic result of linearizing an arbitrary classical field theory around some nontrivial background configuration. This observation explains the ubiquitous nature of the 'analogue models' for general relativity that have recently been developed based on condensed matter physics. In the simple (single scalar field) situation analysed in our previous paper, there is a single unique effective metric; more complicated situations can lead to bi-metric and multi-metric theories. In the present paper we will investigate the conditions required to keep the situation under control and compatible with experiment-either by enforcing a unique effective metric (as would be required to be strictly compatible with the Einstein equivalence principle), or at the worst by arranging things so that there are multiple metrics that are all 'close' to each other (in order to be compatible with the Eotvos experiment). The algebraically most general situation leads to a physical model whose mathematical description requires an extension of the usual notion of Finsler geometry to a Lorentzian-signature pseudo-Finsler geometry; while this is possibly of some interest in its own right, this particular case does not seem to be immediately relevant for either particle physics or gravitation. The key result is that wide classes of theories lend themselves to an effective metric description. This observation provides further evidence that the notion of 'analogue gravity' is rather generic
Replication Data for: "National Personality Traits and Regime Type: A Cross-National Study of 47 Countries"
No full textDomestic theories of democratization emphasize the role of values, interests, and mobilization/opportunities as determinants of regime change. This article takes a step back and develops a model of national personality and democratization to ascertain the indirect effect of national personality traits on worldwide variation of regime type. In particular, I theorize that personality traits influence a country’s regime type by shaping citizens’ traditional and self-expression values, which, in turn, influence the establishment and consolidation of democratic institutions. Data from McCrae and Terracciano’s assessment of the five-factor model from 47 countries allow me to assess this hypothesis empirically. Results reveal that countries whose societies are high in Openness to experience tend to have more democratic institutions, even after adjusting for relevant confounders: economic inequalities, economic development, technological advancement, disease stress, climate demands, and methodological characteristics of the national sample. Although the effect of Extraversion on a country’s democratic institutions is also significantly positive, the inclusion of confounders weakens the reliability of this association. In an exploration of the mechanisms of these associations, a mediation analysis shows that the relationship between national Openness and democratic institutions is channeled through secular and especially self-expression national values. The same analysis with the effect of Extraversion on democracy indicates that the association between this trait and democracy is only channeled through national self-expression values but not national secular values. In short, this article constitutes a first step toward a more complete understanding of the cross-cultural psychological roots of political institutions

Replication Data for: "The Association between Agreeableness, Extraversion, and Support for Secessionist Movements: Evidence from A Large Survey of More Than 33,000 Respondents in Catalonia"
No full textDoes personality influence attitudes toward secessionism? Personality traits are important determinants of a wide range of political attitudes and behaviors. Prior work has mainly focused on the study of personality during regular processes of democratic political systems (e.g., vote choice, turnout, information acquisition, etc.). By contrast, this paper assesses that personality traits have an influence over the decision of individuals to support a secessionist movement. To test this, I rely on a survey distributed to more than 33,.000 respondents in Catalonia, a region with a salient secessionist movement. Beyond the effects of demographic characteristics, political factors, descent-based attributes, economic considerations, and even identity attachments, the results confirm that the personality trait of Agreeableness is associated with supporting the Catalan secessionist movement. Although less consistently, there is some preliminary evidence that extraverted individuals are more likely to support the movement. I conclude that combining insights from political science, sociology and psychology in the study of dispositional and situational determinants of attitudes toward secessionism is fertile research ground
Mass propagation for electromagnetic Schrödinger evolutions
No full textWe investigate the validity of Gaussian lower bounds for solutions to an electromagnetic Schrödinger equation with a bounded time-dependent complex electric potential and a time-independent vector magnetic potential. We prove that, if a suitable geometric condition is satisfied by the vector potential, then positive masses inside of a bounded region at a single time propagate outside the region, provided a suitable average in space–time cylinders is taken

On the interactions between multiple overlapping WLANs using channel bonding
No full textNext-generation wireless local area networks (WLANs) will support the use of wider channels, which is known as channel bonding, to achieve higher throughput. However, because both the channel center frequency and the channel width are autonomously selected by each WLAN, the use of wider channels may also increase the competition with other WLANs operating in the same area for the available channel resources. In this paper, we analyze the interactions between a group of neighboring WLANs that use channel bonding and evaluate the impact of those interactions on the achievable throughput. A continuous-time Markov network model that is able to capture the coupled dynamics of a group of overlapping WLANs is introduced and validated. The results show that the use of channel bonding can provide significant performance gains, even in scenarios with a high density of WLANs, although it may also cause unfair situations in which some WLANs receive most of the transmission opportunities while others starve
