Siendo la textil una rama de industria con una   mayoría de mano de obra femenina, el caso de la casa Gratry, donde el 60% de   los 800 obreros eran mujeres, aparece como ejemplar para la observación de la   actividad de las mujeres en conflicto.   En el trabajo se analiza el rol de las trabajadoras en   la huelga, su participación política, sus formas de organización y   resistencia, haciendo eje en las determinaciones de género y de clase que son   abordadas de manera complementaria e interrelacionada, así como el complejo   entramado de tensiones y solidaridades que éstas generan. De éste modo, se   pretende ahondar en la compleja conformación de una identidad obrera   femenina, a la vez que se discute con aquella mirada historiográfica tradicional   que ha restado importancia a la participación de la mujer en el conflicto   social. Esto se realizará a través de la exploración de una serie de   variables: las relaciones inter-género e inter-clase (fundamentalmente el   vínculo entre las trabajadoras y la patronal masculina), inter-género e   intra-clase (la relación entre trabajadoras y trabajadores), intra-género e   inter-clase (los lazos entre las trabajadoras y las vecinas comerciantes del   barrio), intra-género e intra-clase (relaciones de solidaridad entre   trabajadoras en huelga, y de antagonismo entre huelguistas y “carneras”).   Para ello se trabajó un corpus documental que incluye   información de tipo cuantitativa (las estadísticas del Boletín Informativo   del Departamento Nacional del Trabajo), y cualitativa: periódicos obreros   –fundamentalmente  El Obrero Textil , órgano gremial de la Unión   Obrera Textil,  Semanario de la CGT-Independencia  (órgano de   la Confederación General del Trabajo (CGT)-Independencia) y  La   Vanguardia  (periódico del Partido Socialista), entre otros, y   entrevistas orales a vecinas de Nueva Pompeya y familiares de trabajadoras de   la fábrica Gratry. Se desarrollará una metodología cuali-cuantitativa para el   cruce de estas fuentes.",

One such initiative by private citizens working with Portsmouth NH officials resulted in the installation of energy reducing lighting products on Court St. and the benefits to taxpayers are still coming after over 4 years of operation. This citizen initiative to save money and reduce CO2 emissions, while only one small effort, could easily be duplicated in many towns and cities. Replacing old lamps in just one street fixture with a more energy efficient (Non-LED) lamp has resulted after 4 years of operation ($\\sim $15,000 hr. life of product) in real electrical energy savings of $>$ {\\$}43. and CO2 emission reduction of $>$ 465 lbs. The return on investment (ROI) was less than 2 years. This is much better than any financial investment available today and far safer. Our street only had 30 such lamps installed; however, the rest of Portsmouth (population 22,000) has at least another 150 street lamp fixtures that are candidates for such an upgrade. The talk will also address other energy reduction measures that green the planet and also put more green in the pockets of citizens and municipalities.",

We explore examples of the ways indigenous and non-indigenous people use the Phips Proclamation to illustrate past violence directed against Indigenous peoples. This exploration is enhanced with an analysis of the re-introduction of the Phips Proclamation using concepts of decolonization theory.",

				"abstractNote": "This thesis examines decentralized meta-reasoning. For a single agent or multiple agents, it may not be enough for agents to compute correct decisions if they do not do so in a timely or resource efficient fashion. The utility of agent decisions typically increases with decision quality, but decreases with computation time. The reasoning about one's computation process is referred to as meta-reasoning. Aspects of meta-reasoning considered in this thesis include the reasoning about how to allocate computational resources, including when to stop one type of computation and begin another, and when to stop all computation and report an answer. Given a computational model, this translates into computing how to schedule the basic computations that solve a problem. This thesis constructs meta-reasoning strategies for the purposes of monitoring and control in multi-agent settings, specifically settings that can be modeled by the Decentralized Partially Observable Markov Decision Process (Dec-POMDP). It uses decision theory to optimize computation for efficiency in time and space in communicative and non-communicative decentralized settings. Whereas base-level reasoning describes the optimization of actual agent behaviors, the meta-reasoning strategies produced by this thesis dynamically optimize the computational resources which lead to the selection of base-level behaviors.",

In the network environment, the effects of the sensor saturation, output quantization, and network-induced delay are taken into simultaneous consideration, and the output measurements received in the filter side are incomplete. The random delays are modeled as a linear function of the stochastic variable described by a Bernoulli random binary distribution. The derived criteria for performance analysis of the filtering-error system and filter design are proposed which can be solved by using convex optimization method. Numerical examples show the effectiveness of the design method.",

				"abstractNote": "Northwestern University recently condemned the American Studies Association boycott of Israel. Unlike some other schools that quit their institutional membership in the ASA over the boycott, Northwestern has not. Many of my Northwestern colleagues were about to start urging a similar withdrawal.\nThen we learned from our administration that despite being listed as in institutional member by the ASA,  the university has, after checking, concluded it has no such membership, does not plan to get one, and is unclear why the ASA would list us as institutional member.\nApparently, at least several other schools listed by the ASA as institutional members say they have no such relationship.\nThe ASA has been spending a great deal of energy on political activism far from its mission, but apparently cannot keep its books in order. The association has yet to explain how it has come to list as institutional members so many schools that know nothing about such a membership. The ASA’s membership rolls may get much shorter in the coming weeks even without any quitting.\nHow this confusion came to arise is unclear. ASA membership, like that of many academic organizations, comes with a subscription to their journal. Some have suggested that perhaps  the ASA also counts as members any institution whose library happened to subscribe to the journal, ie tacking on membership to a subscription, rather than vice versa. This would not be fair on their part. A library may subscribe to all sorts of journals for academic research purposes (ie Pravda), without endorsing the organization that publishes it. That is the difference between subscription and membership.\nI eagerly await the ASA’s explanation of the situation. [...]",
