- Small power is a power? The role and resilience of small and medium powers during the Great War 1914-1918Publication . Seminário Internacional "Small Power is a Power? The Role and Resilience of Small and Medium Powers During the Great War 1914-1918"; Telo, António José; Teixeira, Nuno Severiano; Reis, Bruno Cardoso; Gaspar, Carlos Eduardo de Medeiros Lino; Newman, John Paul; Kruizinga, Samuel; Sanz, Carolina Garcia; Almeida, Francisco Eduardo Alves de; Nave, Gaetano de la; Samson, Anne; Afonso, Aniceto; Schmidt, Jan; Pinto, Raquel Vaz; Zary, Julio Cezar; Matos, Sergio Reis; Maximiano, Cezar Campiani; Neto, Sérgio; Lemonidou, Elli; Ionita, Cosmin; Levy, Jack; Mulligan, William; Saraiva, Maria Francisca; Duarte, António Paulo; Dhenin, Miguel; Mendonça, Valterian Braga; Tuna, Cátia Sofia; Rodrigues, Ana Duarte; Ramos, Rui
- Orbitofrontal Cortex Is Required for Optimal Waiting Based on Decision ConfidencePublication . Lak, Armin; Costa, Gil M.; Romberg, Erin; Koulakov, Alexei A.; Mainen, Zachary F.; Kepecs, AdamConfidence judgments are a central example of metacognition-knowledge about one's own cognitive processes. According to this metacognitive view, confidence reports are generated by a second-order monitoring process based on the quality of internal representations about beliefs. Although neural correlates of decision confidence have been recently identified in humans and other animals, it is not well understood whether there are brain areas specifically important for confidence monitoring. To address this issue, we designed a postdecision temporal wagering task in which rats expressed choice confidence by the amount of time they were willing to wait for reward. We found that orbitofrontal cortex inactivation disrupts waiting-based confidence reports without affecting decision accuracy. Furthermore, we show that a normative model can quantitatively account for waiting times based on the computation of decision confidence. These results establish an anatomical locus for a metacognitive report, confidence judgment, distinct from the processes required for perceptual decisions.

- Electron and photon energy calibration with the ATLAS detector using LHC Run 1 dataPublication . ATLAS collaboration (2891 authors); Aguilar-Saavedra, Juan Antonio; Amor Dos Santos, Susana Patricia; Anjos, Nuno; Araque, Juan Pedro; Cantrill, Robert; Carvalho, João; Castro, Nuno Filipe; Conde Muiño, Patricia; Da Cunha Sargedas De Sousa, Mario Jose; Do Valle Wemans, André; Fiolhais, Miguel; Galhardo, Bruno; Gomes, Agostinho; Gonçalo, Ricardo; Jorge, Pedro; Lopes, Lourenco; Machado Miguens, Joana; Maio, Amélia; Maneira, José; Marques, Carlos; Onofre, António; Palma, Alberto; Pedro, Rute; Pina, João Antonio; Pinto, Belmiro; Santos, Helena; Saraiva, João; Silva, José; Tavares Delgado, Ademar; Veloso, Filipe; Wolters, HelmutThis paper presents the electron and photon energy calibration achieved with the ATLAS detector using about 25 fb$^{-1}$ of LHC proton–proton collision data taken at centre-of-mass energies of $\sqrt{s}=7$ and 8 TeV. The reconstruction of electron and photon energies is optimised using multivariate algorithms. The response of the calorimeter layers is equalised in data and simulation, and the longitudinal profile of the electromagnetic showers is exploited to estimate the passive material in front of the calorimeter and reoptimise the detector simulation. After all corrections, the $Z$ resonance is used to set the absolute energy scale. For electrons from $Z$ decays, the achieved calibration is typically accurate to 0.05 % in most of the detector acceptance, rising to 0.2 % in regions with large amounts of passive material. The remaining inaccuracy is less than 0.2–1 % for electrons with a transverse energy of 10 GeV, and is on average 0.3 % for photons. The detector resolution is determined with a relative inaccuracy of less than 10 % for electrons and photons up to 60 GeV transverse energy, rising to 40 % for transverse energies above 500 GeV.
- Metrópolis Golfe & ClubePublication . Vale Santos, Miguel; Barroso de Moura, RuiEste projeto foca-se no conceito do “golfe citadino”, em especial num driving range (bate bolas), aulas de golfe e uma zona de jogo curto. Este espelha a importância do conceito tendo em conta as sinergias que o nosso empreendimento e o tecido empresarial da metrópole Lisboa podem alcançar juntos. Após análise dos atuais players do mercado, nomeadamente possíveis concorrentes, chega-se à conclusão que não existe nenhum empreendimento que possa ser substituto direto do Metrópolis Golfe & Clube. A análise económico-financeira do mercado atual e do golfe em Portugal, permitiu aferir que existe procura para os serviços abrangidos neste projeto. Através do trabalho de campo realizado, entrevistas e questionários, constata-se que o mercado não se encontra totalmente satisfeito, havendo margem para novas ofertas. Considerando um cenário moderado o projeto atinge o seu ponto crítico no quarto ano de atividade, conforme é demonstrado na análise financeira. Por fim, indica-se a equipa que vai gerir este negócio e como se vai obter o financiamento para os 100.000€ necessários para fazer com que este sonho se torne realidade.
