The Mainstream Misrepresentation of Muslim Women in the Media

I discuss the widespread misrepresentation of Islamic women in multiple sources of media and its subsequent effects on the general population\u27s perception of this demographic as a whole

Valuing iconic design: Frank Lloyd Wright architecture in Oak Park, Illinois

This study investigates the willingness of homebuyers to pay for co-location with iconic architecture. Oak Park, Illinois was chosen as the study area given its unique claim of having 24 residential structures designed by world-famous American architect Frank Lloyd Wright, in addition to dozens of other designated landmarks and three preservation districts. This study adds to the limited body of existing literature on the external price effects of architectural design and is unique in its focus on residential architecture. We find a premium of about 8.5% within 50-100m of the nearest Wright building and about 5% within 50-250m. These results indicate that an external premium to iconic architecture does exist, although it may partially be attributable to the prominence of the architec

Blacks are much more likely to be executed for killing whites than whites who have killed blacks

Last year saw the increased popularization of the “#BlackLivesMatter” movement in the wake of the killing of unarmed Black men by police in Ferguson, Missouri, and New York. In new research, Frank Baumgartner, Amanda Grigg, and Alisa Mastro find that in the area of capital punishment, Black lives seem to matter far less than whites’. They find that, since 1976, twice as many blacks have been executed for killing whites than whites have been for killing blacks, and that while Blacks make up 47 percent of all homicide victims, they are only 17 percent of the victims of those executed. They write that despite the arguments of those who feel that #BlackLivesMatter is a redundant movement, the racial disparities apparent in the justice system make it anything but

Liquid Phase Transition in the Postsynaptic Density?

An assembly of scaffold proteins termed the postsynaptic density (PSD) is attached to the postsynaptic membrane of excitatory glutamatergic synapses [1]. The scaffold serves to immobilize glutamate receptors in the membrane directly across from the position where glutamate is released from the presynaptic terminal. It also houses and organizes biochemical machinery whose job is to respond to particular patterns of electrical activity by increasing the strength of the synapse [2]. Synaptic strengthening helps to form new circuits that represent our experience [3]. These circuits are our memories. Biochemical machinery in the PSD strengthens the synapse by increasing the size of the PSD scaffold, the number of anchored receptors, and the size of the presynaptic active zone. A larger scaffold, more release sites, and more receptors means a stronger synapse, and vice versa

A sex difference in the response of the rodent postsynaptic density to synGAP haploinsufficiency

SynGAP is a postsynaptic density (PSD) protein that binds to PDZ domains of the scaffold protein PSD-95. We previously reported that heterozygous deletion of Syngap1 in mice is correlated with increased steady-state levels of other key PSD proteins that bind PSD-95, although the level of PSD-95 remains constant (Walkup et al., 2016). For example, the ratio to PSD-95 of Transmembrane AMPA-Receptor-associated Proteins (TARPs), which mediate binding of AMPA-type glutamate receptors to PSD-95, was increased in young Syngap1+/- mice. Here we show that only females and not males show a highly significant correlation between an increase in TARP and a decrease in synGAP in the PSDs of Syngap1+/- rodents. The data reveal a sex difference in the adaptation of the PSD scaffold to synGAP haploinsufficiency

Enseñanza estratégica en un entorno virtual : un estudio sobre la formación de tutores en educación continua /

Consultable des del TDXTítol obtingut de la portada digitalitzadaNos encontramos ante una época en la que la necesidad de «aprender a aprender» se hace cada vez más urgente. Esta necesidad que se ha extendido a casi todos los rincones de la actividad social como consecuencia de la velocidad de los avances científicos y tecnológicos, y la gran cantidad de información existente que producen permanentes cambios en el mundo actual. Ante este panorama, observamos una creciente demanda de formación permanente en los profesionales que se encuentran en el ejercicio de su carrera, debido a que lo que aprendieron en su formación inicial responde cada vez menos a las demandas del entorno laboral, lo que les plantea retos permanentes ante los cuales necesitan enfrentarse con éxito. Estos retos y demandas no escapan al ámbito de los educadores. De allí, el creciente número de ofertas educativas de actualización docente para mejorar su competencia académica y profesional. En este contexto, los docentes del Perú presentan grandes necesidades de formación permanente para mejorar sus condiciones profesionales y laborales. Pero, también es cierto que el acceso a programas de formación en la modalidad presencial se hace cada vez más difícil para los estudiantes adultos, que tienen que asumir otras responsabilidades personales, familiares y laborales. A ello se añade que, en el Perú, las condiciones económicas y la lejanía geográfica dificultan aún más este acceso. Ante esta situación, la Facultad de Educación de la Pontifica Universidad Católica del Perú, desde hace más de quince años, apostó por la educación a distancia como una alternativa válida de formación permanente, basada principalmente en medios impresos, por resultar más accesible

Minimum Cost Design of Cellular Networks in Rural Areas with UAVs, Optical Rings, Solar Panels and Batteries

Bringing the cellular connectivity in rural zones is a big challenge, due to the large installation costs that are incurred when a legacy cellular network based on fixed Base Stations (BSs) is deployed. To tackle this aspect, we consider an alternative architecture composed of UAV-based BSs to provide cellular coverage, ground sites to connect the UAVs with the rest of the network, Solar Panels (SPs) and batteries to recharge the UAVs and to power the ground sites, and a ring of optical fiber links to connect the installed sites. We then target the minimization of the installation costs for the considered UAV-based cellular architecture, by taking into account the constraints of UAVs coverage, SPs energy consumption, levels of the batteries and the deployment of the optical ring. After providing the problem formulation, we derive an innovative methodology to ensure that a single ring of installed optical fibers is deployed. Moreover, we propose a new algorithm, called DIARIZE, to practically tackle the problem. Our results, obtained over a set of representative rural scenarios, show that DIARIZE performs very close to the optimal solution, and in general outperforms a reference design based on fixed BSs

Viral Load Monitoring of Antiretroviral Therapy, cohort viral load and HIV transmission in Southern Africa: A Mathematical Modelling Analysis

In low-income settings, treatment failure is often identified using CD4 cell count monitoring. Consequently, patients remain on a failing regimen, resulting in a higher risk of transmission. We investigated the benefit of routine viral load monitoring for reducing HIV transmission

Strategic teaching in a virtual context : a study on tutor training in continuing education

Adult students who start a distance-studying program need to develop a strategic learning that allows them to adapt themselves to the demands of distance education and achieve their learning goals successfully. The tutor becomes a fundamental factor when it comes to facilitating these students' adaptation process to distance studying as well as the development of their strategic learning. In this article it is presented a qualitative study on the training process of a group of tutors in strategic distance teaching and learning; it is also presented the analysis of the changes generated in them regarding conceptual and strategic knowledge, both in an academic (as students in the course) and a professional (as tutors) level. Results point out that those tutors who managed to develop higher levels as strategic learners during the training course, accordingly developed a bigger conceptual knowledge and a better performance as strategic tutors
