Robert M. Sauer of the University of Bristol reviews “Economic Modeling and Inference” by Bent Jesper Christensen and Nicholas M. Kiefer. The Econlit Abstract of the reviewed work begins “Graduate-level textbook explores how to combine modern economic theory with the latest statistical inference methods to get the most out of economic data. Discusses components of a dynamic programming model; discrete states and controls; likelihood functions for discrete state/control models; random….”

Graduated control models are often used to explain the variety of government treatment of social organizations in China. These models have been slowly losing their explanatory power in recent years, with advocacy-oriented grass-roots groups participating in the policymaking process. Why are these social groups not regulated in the way the graduated control models predict? Based on an analysis of three recent policy advocacy cases, this article proposes a graduated control 2.0 model to explain the new dynamics in Chinese state–society interactions. The upgraded model argues that the government officials’ behaviour patterns are influenced by numerous factors such as the inherent nature of social groups highlighted by graduated control models, and inter-ministerial competition – the power position of the state sector and its rival sector in the bureaucratic system. Some contingent factors also play a part, such as timing and the NGO’s onstage performance. This research contributes to the ongoing discussion on Chinese state–society relations by developing a theoretical model that highlights both the fragmentation and reactiveness of state control over social groups and further unpacks the ‘monolithic state’ in China studies.

Abstract This study focuses on the control of movable Venetian blinds. Multiple improvements to an existing on/off open-loop control strategy in a case-study apartment have been simulated in TRNSYS 18, thanks to the detailed optical and thermal modelling allowed by the Bidirectional Scattering Distribution Function (BSDF) used as input to the Type56_CFS. The control strategy improvements include the combination of rule-based, closed-loop and discrete state control, in addition to four control strategy activation methods (three use a schedule, and one measures the external temperature). Simulated control inputs include internal temperature, external temperature and vertical irradiance. The results show reductions in overheating, achieved without completely blocking natural illumination or compromising heating demand. While on/off control in winter often leads to increased heating energy consumption, the space sees regular overheating when on/off control is inactive over winter. Conversely, discrete state control is able to more precisely control solar gains in winter to maintain an adequate temperature without utilising the heating system, all the while allowing some level of natural illumination. Ultimately, it is concluded that the choice of the control strategy depends on which objective (minimisation of heating energy consumption, maximisation of daylight harvesting, reduction of overheating risk, etc.) is prioritised.

<p class="resumoabstract">O professor Giorgio Agamben tem elaborado críticas à engenhosa estrutura política ocidental moderna. Avalia os mecanismos de controle estatal, nos quais os denomina ‘dispositivos’, cuja força está na imbricação às normas jurídico-teológicas com seus similares ritos e liturgias. Suas ocorrências e legitimidade preponderam no tecido social cuja organização sistêmica se põe quase como elemento natural e não cultural. O texto tem por objetivo explorar a concepção política de Agamben sobre a política contemporânea, especialmente considerando seu livro: ‘Estado de Exceção’, cuja investigação apresenta a possibilidade de atenuação dos direitos de cidadania e o enfraquecimento da prática da liberdade política e o processo de relação dos indivíduos no meio social através da redução das subjetividades ‘autênticas’. Analisamos ainda a transferência do mundo sacro elaborado pelos teólogos católicos presente na modernidade à política cuja democracia moderna faz do homem (sujeito) tornar-se objeto do poder político. Faz também, reflexão dos conceitos de subjetivação e dessubjetivação relacionando-os às implicações políticas do homem moderno. A pesquisa é bibliográfica com ênfase na análise dos conceitos elaborados por Agamben, especialmente quanto ao ‘dispositivo’. Conclui que o indivíduo ocidental, de modo geral, sofre o processo de dessubjetivação e está ‘nu’, indefeso e alienado politicamente. Ele precisa voltar-se ao processo de ‘profanação’ dos dispositivos para libertar-se das vinculações orientadoras que forçosamente o descaracteriza enquanto ser ativo e livre.</p><p class="resumoabstract"><strong>Palavras-chave</strong>: Política.

It evaluates the mechanisms of state control, in which it calls them 'devices', whose strength lies in the overlap with legal-theological norms with their similar rites and liturgies. Its occurrences and legitimacy preponderate in the social fabric whose systemic organization is almost as a natural and not a cultural element. The text aims to explore Agamben's political conception of contemporary politics, especially considering his book 'State of Exception', whose research presents the possibility of attenuating citizenship rights and weakening the practice of political freedom and the individuals in the social environment through the reduction of 'authentic' subjectivities. We also analyze the transfer of the sacred world elaborated by the Catholic theologians present in the modernity to the politics whose modern democracy makes of the man - subject - to become object of the political power. It also reflects on the concepts of subjectivation and desubjectivation, relating them to the political implications of modern man. The research is bibliographical with emphasis in the analysis of the concepts elaborated by Agamben, especially with regard to the 'device'. He concludes that the Western individual, in general, suffers the process of desubjectivation and is 'naked', defenseless and politically alienated. He must turn to the process of 'desecration' of devices to free himself from the guiding bindings that forcibly demeanes him while being active and free.</p><p class="resumoabstract"><strong>Keywords</strong>: Politics.
