Chicas en Tecnología®: Reiniciando el sistema
by Mariana Varela Carolina Hadad Sofía ContrerasLa tecnología tiene un papel determinante en lo cotidiano: el trabajo, la educación y la vida social. Pero es un área desigual para las mujeres. Este libro da cuenta de la brecha de género en tecnología y de la invisibilización de las pioneras y las líderes, pero es también una invitación a reiniciar el sistema, a que las mujeres consideren a la tecnología como una aliada para mejorar el mundo. La tecnología tiene un papel determinante en lo cotidiano: el trabajo, la educación y la vida social. Pero es un área profundamente desigual para las mujeres. La disparidad comienza en la infancia -a las niñas les regalan una cocinita y a los niños, videojuegos- y continúa durante la escolarización, la formación profesional, la capacitación, en el ambiente laboral o cuando deciden emprender. Las mujeres chocan constantemente con la estigmatización, la mirada estereotipada, la brecha salarial, discriminación y violencia. Cuando en 2015 Sofía Contreras, Carolina Hadad, Melina Masnatta y Mariana Varela crearon la organización Chicas en Tecnología® con el objetivo de achicar la brecha de género en ese campo, el feminismo no tenía la fuerza de hoy en la escena pública, y si bien se ganaron derechos, aún falta mucho. Con datos, fuentes, investigaciones, análisis y la experiencia de las autoras, este libro evidencia las barreras que las mujeres enfrentan en el ambiente tecnológico, pero además propone cambios e ideas en educación, liderazgo, emprendedorismo, mentoreo. Rescata de la invisibilización a las pioneras y demuestra por qué es fundamental que haya cada vez más líderes mujeres y multiplicidad de voces. Chicas en Tecnología® es una invitación a reiniciar el sistema, a que las mujeres consideren a la tecnología como una aliada para mejorar el mundo.
Pyongyang
by Hernan Alberto VanoliCuentos de ciencia ficción política y biológica por uno de los autores jóvenes que más agitan la escena literaria argentina. Una empresa de carpooling convoca almas irredentas que son perseguidas por osos callejeros. Una pareja emprende novedosas técnicas de fertilización y logra sus propios bebés de Rosemary. Una logia mundial de cintas de correr planea una revolución. Y el copamiento de 1989 en La Tablada desemboca en una granja de trolls militada por tiernos ancianos. Las historias de Pyongyang hablan de un totalitarismo suave, cariñoso y veloz, donde hacer un duelo parece imposible, las máquinas nos odian y el progreso es la sagrada ideología oficial. Político y pospolítico, trágico e irónico, imaginativo y cruel, Hernán Vanoli es uno de los autores más singulares del panorama narrativo actual. «Su hiperrealismo lingüístico es un viaje por la sociedad, interesada como nunca en las tribus, los grupos, las fracciones, las camarillas y las bandas.» Beatriz Sarlo

Wiki Media Leaks: La relación entre medios y gobiernos de América Latina bajo el prisma de los cables de WikiLeaks
by Martín Becerra Sebastián Lacunza<P>El explosivo archivo ofrecido por Julian Assange y su organización WikiLeaks ha sido leído y reinterpretado desde diferentes ángulos, y desde cualquiera de ellos sigue revelando una trama compleja y a menudo ocultada de las relaciones internacionales. <P>Este libro aborda en exclusividad el material inédito sobre las tensas relaciones (o acuerdos de convivencia, en algunos casos) entre dueños de medios, periodistas y editores influyentes con los gobiernos latinoamericanos y la Casa Blanca. Se lee también como un gran mapa para saber quién es quién en la red informativa de la región y cómo el periodismo, desde siempre, ha sido un agente más en la construcción del poder político. Los autores, Martín Becerra y Sebastián Lacunza, así lo explican: #Los roles se alternan y se confunden: los medios de comunicación y los políticos o diplomáticos pueden ser fuentes y recolectores de información indistintamente, retroalimentando las versiones que se originan en esos círculos herméticos. En términos de eficacia sistémica, el margen de error en la validez de la información que circula es muy alto, por la endogamia que practican los agentes protagonistas#. <P>En la América Latina del siglo XXI, con nuevas leyes de medios y redefinición del vínculo de los gobiernos con gigantes de las telecomunicaciones y emergentes en el campo periodístico, el material diplomático de las embajadas estadounidenses resulta una crónica documental esencial de las relaciones de fuerza de este tiempo singular. Su propio contenido explica los silencios que se han registrado a la hora de difundir los cables de WikiLeaks, que este trabajo aspira a iluminar.

Muchos no saben que esa parte es solo la punta de un iceberg comunicacional en el cual su mole sumergida multiplica muchas veces la red de acceso natural. Este sector es el llamado Deep Web (Internet Profunda) que contiene a su vez a la DarkNet (la Red Oscura), organizada en varios círculos, cada vez más profundos y con mayor dificultad de acceso, y donde solo se puede navegar con motores especiales de búsqueda. En ella se libran luchas planetarias de todo tipo entre imperios, terroristas y rebeldes, comercios ilegales, sórdidos vídeos y se replican amenazas constantes hacia la seguridad y el bienestar de la gente. <P> Entender esta parte de la existencia que se ha instalado entre nosotros es de capital importancia para proteger nuestras vidas. Nadie puede quedar al margen de estos conocimientos. La amenaza de Internet Profunda está entre nosotros y nos involucra a todos. Solo conociéndola en sus más recónditos espacios nos podrá prevenir, única manera de salvarnos de los peligros que encierra. Si usted quiere iniciar un viaje a las profundidades de la red, Deep Web es un libro imprescindible
Pacific Crossing
by Elizabeth SinnDuring the nineteenth century tens of thousands of Chinese men and women crossed the Pacific to work, trade, and settle in California. Drawn initially by the gold rush, they took with them skills and goods and a view of the world which, though still Chinese, was transformed by their long journeys back and forth. They in turn transformed Hong Kong, their main point of embarkation, from a struggling infant colony into a prosperous international port and the cultural center of a far-ranging Chinese diaspora. Making use of extensive research in archives around the world, Pacific Crossing charts the rise of Chinese Gold Mountain firms engaged in all kinds of transpacific trade, especially the lucrative export of prepared opium and other luxury goods. Challenging the traditional view that the migration was primarily a "coolie trade," Elizabeth Sinn uncovers leadership and agency among the many Chinese who made the crossing. In presenting Hong Kong as an "in-between place" of repeated journeys and continuous movement, Sinn also offers a fresh view of the British colony and a new paradigm for migration studies.

Viver sem plástico: Um guia para mudar o mundo e acabar com a dependência do plástico
by Will McCallumUm guia para mudar o mundo e acabar com a dependência do plástico. Todos os anos, cerca de 13 toneladas de plástico são largadas nos oceanos, matando mais de 1 milhão de aves e 100 000 mamíferos marinhos. Estima-se que, em 2050, o peso do plástico que invade os oceanos será superior ao peso do peixe que neles habita. A poluição pelo plástico é o flagelo ambiental da nossa era. Como podemos fazer a diferença? Neste guia claro e esclarecedor, Will McCallum, destacado activista antiplástico, vai ajudá-lo a levar a cabo pequenas mudanças que farão uma enorme diferença. Eis alguns conselhos práticos: - Lavar a roupa em sacos próprios, de modo a conter as microfibras de plástico, responsáveis por 30% da poluição por plástico nos oceanos - Substituir o champô vulgar por champô em barra - Evitar as embalagens de supermercado - Fazer festas de aniversário livres de plástico - Convencer os outros a juntarem-se a si nesta demanda O plástico não vai desaparecer sem dar luta. É preciso um movimento feito de milhões de pequenos gestos individuais, que juntarão pessoas de todas as origens e culturas, pessoas cuja vontade se fará sentir por toda a parte, desde a mais pequena aldeia ao mais alto dos arranha céus. Este é um apelo à luta: para unirmos forças, em todo o mundo, e acabarmos com a dependência do plástico.
La ciencia es cosa de mujeres
by Margarita MicheliniLas once científicas uruguayas retratadas en este libro cuentan sus sueños, su día a día, sus logros y sus peajes. No es casualidad que en el nivel más alto del Sistema Nacional de Investigadores haya una mujer por cada 3,4 varones. Tampoco que en los grados iniciales la participación femenina se equipare a la de ellos. Habla de una lógica de obstáculos y prejuicios, más o menos conscientes y vastamente estudiados, que lentamente va cambiando. Las once científicas uruguayas retratadas en este libro cuentan sus sueños, su día a día, sus logros y sus peajes. Estas páginas guardan la esperanza de contagiar a quienes se plantean seguir sus pasos y a los lectores todos, para que puedan darle a su labor el lugar que merece. Sin ellas, la ciencia tendría otro tinte. Trabajan con pasión, la mayoría en silencio, en temas que parecen lejanos y sin embargo repercuten en la vida de todos. Productos naturales que contrarres-ten el uso de plaguicidas, sistemas de información para cuidar el ambiente, el amor por partículas tan imperceptibles como poderosas, el tesón de una loca idea, la estadística aplicada para modelar el comportamiento del SARS-CoV-2 y la carrera para fabricar en Uruguay un kit para detectarlo se cruzan con una científica emprendedora, una doctora del clima especialista en enfrentar temporales, una experta en mecatrónica que hace hablar a las máquinas o una jugadora de elite en las matemáticas. Cuando la creatividad y las neuronas se conjugan con entrega, el resultado no tiene límites.
Bees, Honey and Beekeeping in the United Arab Emirates
by Denis L. Anderson Ihsan Abu AlrubBees and Beekeeping in the United Arab Emirates (UAE) marks the first publication in the UAE of a book focusing on bees, honey bees, and beekeeping. Wild and managed bees are known as "keystone species" because of their significance as pollinators of flowering plants in nature and agriculture, but despite this, little is known about bees in the UAE. This book is designed to captivate a broad audience, blending general knowledge about the diversity, significance, and conservation of bees with specific insights into challenges unique to honey bees (Apis mellifera) in the UAE. Key topics include sustainable beekeeping practices, managing hives in hot, arid environments, and identifying and addressing major pests and diseases. Special attention is given to the wild dwarf honey bee (Apis florea), a prevalent species in the UAE. While not a basic guide to beekeeping, this book offers valuable information for both novice and experienced beekeepers.
Einstein en Uruguay: Crónica de un viaje histórico
by Diego MoraesUn exhaustivo trabajo de investigación en el que Diego Moraes reconstruye el viaje de uno de los personajes más importantes en la historia de la humanidad y un Uruguay a la vanguardia de la cultura y el pensamiento. En 1925 el famoso físico alemán Albert Einstein realizó una histórica visita al Uruguay. Casi cien años han pasado desde entonces pero, en la actualidad, ¿qué sabemos los uruguayos sobre aquel episodio? Una estatua ubicada en la Plaza de los Treinta y Tres, en el Centro montevideano, recuerda el momento más famoso de aquella visita: el célebre encuentro mantenido en ese mismo sitio entre Einstein y el filósofo Carlos Vaz Ferreira. Sin embargo, es poco más lo que se conoce, en términos generales. ¿Qué vino a hacer Einstein al Uruguay? ¿Quién lo invitó a nuestro país y por qué? ¿Qué personajes prominentes de la sociedad uruguaya conoció durante su estadía? ¿Dónde se alojó? ¿Qué actividades realizó durante la semana que permaneció en suelo uruguayo? ¿Qué impresión dejó entre los compatriotas de 1925? E, inversa mente, ¿qué opinión guardó luego de su paso por estas tierras? Estas son solo algunas de las preguntas que este libro aspira a responder.
