Unbounding ‘states of exception’, reconceptualizing precarity

ABSTRACT This provocation unbounds ‘state of exception’ to account for its sustainability and its role in daily life. I argue that sustaining a ‘state of exception’ requires a governmentality to govern and render the exceptional ‘normal’ over time, pointing to the mutual constitution of the two modes of governance. The omnipresent condition of possible shifts between sovereignty and governmentality relocates precarity from a statically defined objectified circumstance to the active slippage between these two fields of power. Yet whereas a ‘state of exception’ can become normalized, subjectivity cannot because the configuration of individuals’ multiple subjectivities differs relative to their lived experiences.

Planejamento metropolitano e grandes projetos urbanos: concepção e descaminhos da política de novas centralidades na RMBH

Resumo Nas últimas décadas, dois processos caracterizaram a política e a dinâmica urbana da Região Metropolitana de Belo Horizonte (RMBH): a retomada do planejamento metropolitano e a maior intensidade de grandes projetos urbanos (GPUs). Este trabalho investiga criticamente as relações entre um conjunto de GPUs, executados e/ou idealizados entre 2000 e 2018, e o planejamento em construção, com ênfase nos projetos para centralidades nos Vetores Norte e Sul da RMBH. Para tal, busca-se articular a análise do campo de poder dos GPUs com a análise do processo de planejamento. As conclusões evidenciam aproximações, contradições e descaminhos entre o planejamento, o Governo do Estado e o capital imobiliário, principalmente quanto à política de novas centralidades.

Ethics Events and Conditions of Possibility: How Sell-Side Financial Analysts Became Involved in Corporate Governance

Mobilizing Foucault’s genealogy, this article investigates how an “ethics event,” that is, the involvement by some sell-side financial analysts in the US and UK across the past two decades in corporate governance, emerged. It is found that the complex relations formed between specific historical precedents, normative discourses, and fields of power rendered certain issues in financial markets morally problematic and constructed analysts’ corporate governance work as a potential solution. Contributing towards finance ethics research, this article develops a novel perspective to conceptualize the rise of ethically relevant practices in financial markets, focusing on how ethical problems and their solutions are outcomes of discursive construction and power relations. This article also revises our understanding of the boundary between technical norms and moral norms in financial markets. When ethical crises occur, it is argued, transforming technical practices and revising the technical norms adopted by financial professionals has potential for tackling ethical concerns.

We show the importance of development and implementation of new hydrogen power systems for different branches of the Ukrainian economy. It is determined that the key technologies for the creation of hydrogen power in Ukraine are the technologies of hydrogen production using own energy sources and the direct conversion of chemical energy of hydrogen fuels into electricity in fuel cells. We present the main characteristics and advantages of fuel cell power plants (FCPP) and the global volume of their application for different industries. The total electric capacity of FCPP working in 2019 became more than 11 times greater as compared with 2009 and reached 1,100 MW. It was established that the introduction of fuel cell technologies in industrialized countries is considered as a basis for the creation of a centralized world hydrogen economy with the presence and further development of extensive hydrogen infrastructure. The state of work on standardization in the field of hydrogen power at the international level is analyzed, and the complexity and multiplicity of such tasks are shown. It is substantiated that the appropriate base of normative documents is necessary for the practical implementation of energy-efficient and environmentally friendly hydrogen technologies in Ukraine, in particular, for the production or import of equipment with its subsequent certification. These normative documents should be harmonized with European and international ones in order to remove possible technical barriers in trade.

The model coil manufacture and AC losses analysis of a 100-MJ HTS SMES

The second generation of high temperature superconducting (HTS) strip has the outstanding characteristics of high critical temperature, high load current density and high critical magnetic field, so the HTS coils wound by the strip have broad application prospects in the field of electric power, such as magnetic energy storage system, high speed maglev train and wind power generation system. In order to promote the further development of HTS magnetic energy storage system (SMES), this paper conducts the modelling and simulation research on the ac losses of a 100- MJ toroid-type HTS SMES. Firstly, the geometric structure of the system are introduced. Then, the ac loss models of HTS coils and the non-superconducting components in the energy storage system are established by H-formulation and A-formulation, respectively. Based on both the models, we calculate the ac losses of HTS coils and related components during the process of energy storage and release. Finally, the model coils are winded and impregnated to show the structure.

The second generation of high temperature superconducting (HTS) strip has the outstanding characteristics of high critical temperature, large current-carrying density and high critical magnetic field, and the HTS magnets made by the strip have broad application prospects in the field of electric power, such as magnetic energy storage system, high-speed maglev train and wind power generation system. In order to promote the further development of a superconducting magnetic energy storage (SMES) system, this paper conducts modelling and simulation research on the AC losses of single solenoid type magnet for 10 kJ SMES system. Firstly, this paper optimizes the geometric parameters of the HTS magnet in the SMES system, in which the inner diameter, turns and pancake number of the superconducting magnet are the optimization variables, energy storage is the constraint condition, and the total consumption of the HTS strip is the optimization objective. Secondly, based on the T-A method, this paper established the AC loss model of single solenoid HTS magnets and calculated the AC losses of HTS magnets and thermal-conducting copper plates during the energy storage and energy release of the energy storage system.

Avoiding Complex and Nonlinear Behaviour of Multilevel Power Inverter

In the present scenario to meet out the goal, recent technology of multilevel inverter has introduced which helps to provide a very useful alternative in the field of huge power and a moderate range of voltage applications. Under this work, an attempt has been made to study the complex nature due to nonlinearities and chaos in cascaded multilevel dc to the ac converter system. Nonlinear behavior phenomena are observed in three-phase inverter and cascaded multilevel H-bridge inverter using Matlab / Simulink software package. By various observations, it is reported that the dc to ac converter shifted their position from a stable operating condition to unstable operating conditions as the bifurcation parameter like load varied for the power inverter system. Simulation results obtained through software Matlab / Simulink demonstrate output voltage and current waveform of inverter along with its FFT spectrum. This study for getting information about the nonlinear behavior of power multilevel inverter system is playing a very vital role in designing and fabrication of practical circuits in the power electronics field.

Pierre Bourdieu on social transformation, with particular reference to political and symbolic revolutions

This article challenges what is now the orthodoxy concerning the heritage of Bourdieu (1930–2002): namely, the judgement that his distinctive sociological innovation has been his theory of social reproduction, and that he has failed to provide a necessary theory of social change. Yet Bourdieu consistently claimed to offer a theory of social transformation as well as accounting for continuities of power. Indeed, he provides two substantive keys for an understanding of historical transformation—first, a theory of prophets (religious or secular) as the authors of heresies or “symbolic revolutions” that dispel current doxa; second, a theory of the “corporatism of the universal”: the role of intellectuals or other educated professionals in pursuit of social justice and other universalistic goals. Moreover, Bourdieu fuses his theories of “symbolic revolutions” with a materialist analysis of their social preconditions, including a fresh account of social crises. Crises—war, famine, recession, and especially the intensified precarity of the educated—have, for him, a profound impact, both within differentiated fields and across fields. Conflicts that become effectively synchronized across fields acquire great resonance within the wider field of power, particularly due to hysteresis or “maladjusted habitus.” Indeed, the appearance of crises, together with new prophetic heresies, leads the subordinate classes to question the taken-for-granted order of things and to orchestrate their resistance. Alongside his corpus of published writings, this article draws widely on Bourdieu’s posthumously published lectures. These cast a distinctive new light on how his well-known conceptual instruments can aid us in the study of historical change. They also expand on how social science itself might be used to facilitate progressive social movements.

Playing the fields: Theorizing research impact and its assessment

Abstract How research is assessed affects what types of knowledge are valued, incentivized, and rewarded. An increasingly important element of contemporary research evaluation is the measurement of the wider impact of research (e.g. benefit to society, culture or economy). Although the measurement of impact has been highly contested, the area is under-theorized and dominated by pragmatic research policy imperatives. Informed by a sociological perspective, this article intervenes in this context by reframing research impact as the attainment and maintenance of capital (i.e. symbolic power or status) in various fields beyond academia. It argues that research impact occurs at the intersection of these fields of power. The article shows that impact involves various combinations of capital from the scholarly field, the field of politics, the field of application, the media field, and the economic field, which provide credibility, authority, utility, visibility, and weight, respectively. In exploring the forms of worth and value that underpin the pursuit of legitimacy in these fields, the article provides a new theoretical framework for understanding research impact and its assessment.

Os economistas-colunistas no debate sobre as reformas no Brasil

Esta pesquisa analisou a dinâmica estabelecida entre as posições dos economistas-colunistas no campo do poder e suas tomadas de posição acerca da PEC 241 e das reformas da Previdência e a Trabalhista. Para tanto, adotamos como objeto os colunistas economistas dos principais jornais generalistas do país – Folha de S.Paulo, O Estado de S. Paulo e O Globo. Delineando suas posições em relação aos poderes econômico e político assim como ao campo acadêmico e à mídia e analisando os discursos proferidos acerca das reformas, foi possível compreender as trocas simbólicas que esses agentes estabelecem entre si bem como com os jornais em que escrevem. Sublinhamos, ainda, a importância desses agentes para a ratificação e reiteração de determinados projetos para o país, como difusores de uma doxa forjada em lugares nos quais agentes provenientes de diferentes campos sociais estabelecem trocas.

Emerging technologies in the renewable energy sector: A comparison of expert review with a text mining software

This paper compares the results from quantitative text mining to qualitative expert reviews to identify emerging technologies in the fields of solar photovoltaics (PV), wind power, ocean and tidal energy, hydropower. The text mining analysis is based on the software “Tools for Innovation Monitoring” (TIM). The TIM software extracts a set of relevant keywords from a corpus of pertinent scientific publications. TIM outputs are compared to those extracted by the software VOSviewer, showing agreement. The top 300 ranked keywords are the optimum trade-off between retrieved technologies and analyst efforts. The emerging technologies identified by the experts can be retrieved in the top 300 keywords with a probability of 65 %, 25 %, depending on the technology sector and the algorithm adopted. The more salient keywords tend to correspond to technologies with an established and univocal jargon such as: "dye sensitised solar cells" or "vertical axis wind turbines". Two methods are here used and compared: the frequency of author keywords and the term frequency-inverse document frequency (TF-IDF) algorithm. The comparison of their performances is not showing a general prevalence of one method against the other, but rather a different suitability to different technology sectors.

Political Field and Zone of Power: Ideal Type Varieties and an Empirical Verification

In the article, the concepts “political field” and “zone of power” are analyzed in order to evaluate their applicability to the sociologacal study of conditions for emergence of modern-type politics in Russia – based on goal-setting and competition. The attempted conceptualization was based on neoinstitutional, deliberative and neo-republican approaches. Models developed by the authors were verified using the data of a 2018 nationwide representative population survey. It is demonstrated that, according to different understanding of rules and their role in politics, political sphere in Russia is precieved either as a closed and deformalized zone of power or as an open political field. These perceptions influence how the possibility of interests’ realization in politics is assessed and how attitudes towards participation are formed. The approaches used in the article also help to reveal how the zone of power can potentially be transformed into political field.

Synthesis of robust control algorithms for linear interval dynamic systems in the electric power industry

When studying the objects of management in the field of electric power, we meet with various inaccuracies in determining their parameters. One of the methods of dealing with uncertainties is the use of various estimates of the parameters of the control object. modern science has developed various methods for assessing the uncertain parameters of the control object in the electric power industry. parameter uncertainty occurs when the set of parameters of the control object is more than one point. If this set is defined using probabilistic characteristics, then this is the so-called probabilistic uncertainty of the object parameters. If the boundaries of the intervals in which they are enclosed are known for the object parameters, then such uncertainty is called interval uncertainty. if the object parameters are set using the membership function, then the theory of fuzzy logic is used. Interval determination of parameters of the control object is used when working with values for which only the boundaries of the intervals within which their values are enclosed are known. The interval approach in the description of object parameters is used to account for rounding and errors that occur during calculations on a computer and is a strong method in the representation of objects with uncertain parameters, which are very common in the electric power industry. The reason why interval systems are used is the incompleteness of information about the control object, errors in measuring the parameters of the object, linearization errors, and so on. Various problems of the classical theory of automatic control allow us to replace the concentrated parameters with their interval analogues. Many interval problems are adequate for practical applications. The synthesis of linear quadratic regulators refers to the classical method, which allows us to obtain regulators that minimize the integral quality criterion with respect to the resource of regulated and regulatory quantities. In this paper, we study the possibility of synthesizing linear quadratic regulators for electric power facilities specified in intervals. This application of two well-known methods makes it possible to work with nonlinear objects using the classical linear control theory.

Atomic diagnostics of ultrahigh laser intensities

SynopsisWe suggest and discuss a method for precise measurement of ultrahigh laser intensities in the 1020 – 1024W/cm2 range of intensities. The method is based on the observation of multiple sequential tunneling ionization of heavy atoms in the focus of an intense laser beam. It can be of use for probing electromagnetic fields of record power expected to achieve at new multi-petawatt laser facilities.

Study on Electrical Characteristics of Titanium Diboride Powder Applied in Power Field

Based on the properties of Titanium Diboride (TiB2) combined with the knowledge of electrical engineering, a novel application of TiB2 in the field of electric power has been proposed. The contact resistance of the particulate matter changes greatly when the external stress changes. Therefore, particulate matter can be used as a variable resistor in the field of fault current limiting. First, the pressure-resistance characteristics of TiB2 were studied experimentally, and the law of resistance change with pressure was summarized. The explanation was given from the perspective of particle mechanics. Then, combined with the operating mechanism, a device with variable resistance was fabricated. And the curve of material resistance with time was tested. Finally, the material was passed through current, which proved that the material properties have not changed under large current. Thus the feasibility of the application of the material in the power field was verified.
