This piece is a short rejoinder to César Bolaño’s paper The Political Economy of the Internet and related articles (e.g., Comor, Foley, Huws, Reveley, Rigi and Prey, Robinson) that center around the relevance of Marx’s labor theory of value for understanding social media. I argue that Dallas Smythe’s assessment of advertising was made to distinguish his approach from the one by Baran and Sweezy. Smythe developed the idea of capital’s exploitation of the audience at a time when both feminist and anti-imperialist Marxists challenged the orthodox idea that only white factory workers are exploited. The crucial question is how to conceptualize productive labor. This is a theoretical, normative, and political question. A mathematical example shows the importance of the “crowdsourcing” of value-production on Facebook. I also point out parallels of the contemporary debate to the Soviet question of who is a productive or unproductive worker in the Material Product System.

Analisa uma proposta de um controlador digital para o regulador de velocidade da Usina Hidroelétrica de Curuá-Una, utilizando duas estratégias de projeto, a estratégia indireta com o projeto do controlador sendo feito no plano contínuo e depois discretizado e a estratégia direta, em que o controlador é projetado inteiramente no plano discreto. O conhecimento gerado no simulador é de grande importância, pois é uma das grandes ferramentas para avaliar o comportamento dos controladores digitais propostos, em ambiente seguro. O estudo dos controladores também permite uma substituição de equipamentos antigos, com produção descontinuada, por equipamentos novos que permitem a confecção de controladores modernos, digitais e inteligentes, que proporcionam uma substituição de técnicas antigas de controle por estratégias avançadas de controle, maximizando o rendimento do sistema em condições adversas de operação. O trabalho levanta as diferenças, vantagens e desvantagens de cada controlador, com o objetivo de auxiliar na escolha do controlador mais adequado para projetos de controladores avançados: tipo um controle adaptativo, controle fuzzy ou controle neural. As dificuldades de projeto e os resultados das simulações foram os principais indicadores na avaliações dos dois RV digitais projetados. De uma forma geral o RV digital direto apresentou melhor desempenho, estabilidade e menor esforço computacional, entretanto, o RV digital indireto mostrou desempenho similar, menor degradação devido às não linearidades e ao menor esforço de projeto.

This memoir chronicles the three summers I spent working in the factories at Chestnut Hill Gazebos. It focuses on three narrative strands: the day-to-day life of a factory worker, the struggles within and eventual breakdown of my relationship with my girlfriend, and how my job at Chestnut Hill helped me critique my fundamentalist Christian roots by forcing me into a deeper understanding of my faith and its relationship to the world outside the confines of my upbringing. The critical afterword uses essays by Leona Toker and other theorists as a framework for understanding how I approached several different problems when writing my memoir, such as how to present incomplete memories of events, whether or not to condense events for the sake of a more streamlined narrative, and whether or not a memoirist should use composite characters. I explain how various practitioners and critics influenced my decisions, and I also compare my approach to the practices of other memoirists.

Luke Banas is a young video artist who lives illegally in the disused Domino sugar refinery in Williamsburg, Brooklyn. While his art is an attempt to fully record and share his own life story, developers want to tear down the building where he works; a building that’s a monument to his hip neighborhood’s industrial past. The novel’s narrator, Lila Fairfax, is a journalist writing her first feature article about Luke and the fate of the factory. Observant and astute, she soon realizes that, despite his obsessive self-revelation, Luke is hiding a secret. Lila’s rational, detached approach to life is disrupted as, in the course of her reporting, she falls in love with Luke and as a result, learns far more than she anticipated. Though primarily a love story, The Sugar Factory is also an investigation of art, and art’s interaction with commerce, history, and new technology.
