It is known that interval type-2 fuzzy logic controllers (IT2FLC) with footprint of uncertainty (FOU) in terms of membership function (MF) have been developed as an effective control method to ensure control in systems where uncertainties and nonlinear situations are high, such as quadrotor control, and have been the subject of many studies. Designing and optimising parameters of IT2FLC controllers is complex and time-consuming. To overcome this situation, an optimisation method based on NSGA-II (Non-dominated Sorting Genetic Algorithm) was applied. ITAE (Integral Time Absolute Error) was chosen as the performance criterion. IT2FLC-NSGA-PID and NSGA-PID controllers were compared and it was observed that the IT2FLC-NSGA-PID controller gave better results. As a result, the superiority of the proposed controller over the other controllers is a better overshoot ratio, a faster settling time, a lower steady state error and a robust system response against uncertainties and disturbances in nonlinear systems.
Many attempts have been made to capture the essence of manipulation in a definition, but all have arguably failed. Exploring an alternative strategy, this chapter provides an account of “manipulation” as a cluster concept. Roughly, cluster concepts are characterized by sets of criteria none of which is necessary for the applicability of the cluster concept term; the different subsets of criteria that instantiate the concept are characterized by “family resemblance,” and the more criteria an instance possesses, the closer it is to be prototypical of the concept. The chapter provides a set of ten criteria that participate in the constitution of “manipulation.” They are: intention (kind); intention (intensity); getting into the target’s head; exploiting psychological vulnerability; bypassing or subverting rational control; nontransparency; effect on the target; whether the influence is exercised for the sake of the influencer; making the target a pawn in the influencer’s grand plan; and low baseline expectation of influence. Chapter 2 claimed that the concept “manipulation” is diagnosed perceptually; this fits well with understanding “manipulation” as a cluster concept, since perception determines which combinations of criteria qualify as manipulation.
The Second Sino-Japanese War (1937-1945) occupies an integral position in the memory politics of the People's Republic of China (PRC). In recent years, dominant representations of the war create a memory discourse which portrays the heroic triumph of the Chinese people led by the Chinese Communist Party (CCP) over Japan. This article shows how the war has been remembered from the victory of the Communist revolution in 1949 to the present in the PRC. It contributes to the debate on the effectiveness and limitations of the monopoly of war memory by the CCP.
Despite its relative invisibility to most people living in the urban Asia-Pacific, endemic malaria occurs across the region. The unique character of Asian-Pacific malaria includes a serious problem of drug resistance, dominance of a particularly difficult species to control and treat, and another that normally dwells in monkeys but often infects humans. Most nations in the region with endemic malaria have called for its elimination by the year 2030. Meeting that ambitious goal will require mobilizing technical and financial resources, and social and political will. Malaria is a formidable foe fully capable of defeating halfhearted efforts to eliminate it.
We report four repetitions of Falk and Kosfeld's (Am. Econ. Rev. 96(5):1611—1630, 2006) low and medium control treatments with 476 subjects. Each repetition employs a sample drawn from a standard subject pool of students and demographics vary across samples. We largely confirm the existence of hidden costs of control but, contrary to the original study, hidden costs of control are usually not substantial enough to significantly undermine the effectiveness of economic incentives. Our subjects were asked, at the end of the experimental session, to complete a questionnaire in which they had to state their work motivation in hypothetical scenarios. Our questionnaires are identical to the ones administered in Falk and Kosfeld's (Am. Econ. Rev. 96(5):1611—1630, 2006) questionnaire study. In contrast to the game play data, our questionnaire data are similar to those of the original questionnaire study. In an attempt to solve this puzzle, we report an extension with 228 subjects where performance-contingent earnings are absent i.e. both principals and agents are paid according to a flat participation fee. We observe that hidden costs significantly outweigh benefits of control under hypothetical incentives.
We conduct a field experiment with Amazon Mechanical Turk (“AMT”) workers to causally assess the effect of introducing a control mechanism in an existing work relationship on workers’ performance on tasks of varying difficulty. We find that introducing control significantly reduces performance. This reduction occurs primarily on challenging tasks, while performance on simple tasks is unaffected. The negative effects are primarily driven by workers who exhibit non-pecuniary motivation in the absence of control. Our results show that there are adverse effects of control, and they suggest that these adverse effects are of particular concern to firms that rely on high performance on challenging tasks.
This paper constitutes the first economic investigation into the potential detrimental role of smartphones in the workplace based on a field experiment. We exploit the conduct of a nationwide telephone survey, for which interviewers were recruited to work individually and in single offices for half a day. This setting allows to randomly impose bans on the use of interviewers’ personal smartphones during worktime while ruling out information spillovers between treatment conditions. Although the ban was not enforceable, we observe substantial effort increases from banning smartphones in the routine task of calling households, without negative implications linked to perceived employer distrust. Analyzing the number of conducted interviews per interviewer suggests that higher efforts do not necessarily translate into economic benefits for the employer. In our broad discussion of smartphone bans and their potential impact on workplace performance, we consider further outcomes of economic relevance based on data from employee surveys and administrative phone records. Finally, we complement the findings of our field experiment with evidence from a survey experiment and a survey among managers.
This chapter develops an approach to restructuring with control verbs in German that is based on the operation Remove. The approaches to restructuring in infinitival constructions developed over the last three decades postulate either uniformly monoclausal structures or uniformly biclausal structures, that is, they do not actually rely on a concept of syntactic restructuring. Against this background, the goal of this chapter is to outline an approach to restructuring with control verbs in German that radically departs from standard approaches in that it presupposes that genuine syntactic restructuring does indeed exist, and can be held responsible for conflicting pieces of evidence that suggest both a monoclausal and a biclausal structure. The chapter is organized as follows. Following an illustration of infinitival constructions in German, I present conflicting evidence for restructuring with control verbs in German: There are arguments for a monoclausal analysis and there are arguments for a biclausal analysis. The Remove-based approach is shown to capture both the evidence for monoclausality and the evidence for biclausality.
In this chapter, I pursue two main goals. First, I argue for a new empirical generalization: An external argument in German passive constructions is accessible from positions below it but inaccessible from positions above it. The evidence for downward accessibility comes from control into adjunct clauses, secondary predicates, and complement clauses, binding of reflexives and reciprocals, and disjoint reference effects. In contrast, the evidence for upward inaccessibility comes from long-distance binding in impersonal passives and standard passives, accessible subjects for control infinitives, criterial movement constraints, minimality of movement effects, and intervention for anaphoric binding. Second, I present a new theory of passivization from which this generalization can be derived: The elementary operation Remove accounts for both accessibility and inaccessibility of external arguments in the passive in German, by correctly predicting a short life cycle. After this, the chapter addresses the question of how variation in the area of passivization can be accounted for in the new model. Next, there is a brief extension of the analysis to adjectival passives, invoking external Remove. The chapter concludes with a discussion of alternative approaches that either maintain strict accessibility or postulate strict inaccessibility, as well of hybrid approaches.
Understanding the complex dynamics of climate patterns under different anthropogenic emissions scenarios is crucial for predicting future environmental conditions and formulating sustainable policies. Using Dynamic Mode Decomposition with control (DMDc), we analyze surface air temperature patterns from climate simulations to elucidate the effects of various climate-forcing agents. This improves upon previous DMD-based methods by including forcing information as a control variable. Our study identifies both common climate patterns, like the North Atlantic Oscillation and El Niño Southern Oscillation, and distinct impacts of aerosol and carbon emissions. We show that these emissions’ effects vary with climate scenarios, particularly under conditions of higher radiative forcing. Our findings confirm DMDc’s utility in climate analysis, highlighting its role in extracting modes of variability from surface air temperature while controlling for emissions contributions and exposing trends in these spatial patterns as forcing scenarios change.
Oscar Barbarin has served on the faculties of the Universities of Michigan, Maryland, and North Carolina as well as Tulane University. His scholarship examines social context, ethnicity and child development, particularly the impact of racism and material hardship on socioemotional development. He has studied the development of children with life-threatening illness, urbanization in South Africa, and quality of early childhood settings. His research has centered on boys of color and the identified auspicious conditions that promote their mental health, social competence and emotional resilience. These conditions include (a) systems of caring, (b) structures supporting their self-regulation of behavior and emotions, and (c) interpretive frameworks by which affirming familial relations, culture and spiritual values provide boys of color a sense of connection, purpose, and an understanding of their place in the world. He has proposed that paradoxical attributions are a key cognitive strategy in maintaining emotional balance by affirming personal agency.
In this paper, fractional-order (FO), intelligent, and robust sliding mode control (SMC) and stabilization of inherently nonlinear, multi-input, multi-output 6-DOF robot manipulators are investigated. To ensure robust control and better performance of the robot system, significant studies on various control transactions have been explored. First, a sliding proportional-integral-derivative (PID) surface is conceived and then its FO constitute is developed. It is an important fact that in SMC, the reaching phase is fast and the chattering is abated in the sliding phase. In particular, the discontinuity in the SMC is prevented in view of the boundary layer obtained by recommending the sigmoid function together with fuzzy logic to eliminate the chattering phenomenon. A hybrid tuning method consisting of gray wolf optimization and particle swarm optimization (GWO-PSO) algorithms is applied to tune the parameters of PID sliding mode control (PIDSMC), FO PIDSMC (FOPIDSMC), fuzzy PIDSMC (FPIDSMC), and FO fuzzy PIDSMC (FOFPIDSMC) controllers. In simulation results, the tuned FOFPIDSMC controller consistently outperforms PIDSMC, FOPIDSMC, and FPIDSMC controllers tuned by the GWO-PSO in dynamic performance, trajectory tracking, disturbance rejection, and mass uncertainty scenarios. It has been seen through a thorough performance analysis that 91.93% and 44.13% improvement are, respectively, obtained for mean absolute error (MAE) and torques root mean square (RMS) values of the joints when using from the PIDSMC to the FOFPIDSMC. Finally, the simulation outcomes reveal the superior aspects of the designed FOFPIDSMC and also demonstrate that the FOFPIDSMC controller enhances the dynamic performances of the 6-revolute universal robots 5 (6R UR5) robot manipulator under a variety of operating conditions.
Economic inequality is not the only form of inequality in urban contexts. In this chapter, I discuss other forms of marginalization in public spaces. Although my main focus is on social relations among citizens, the state’s control of public spaces is consequential in creating and sustaining structural inequalities that directly or indirectly impact social relations in public spaces. Whether controlling appearance and behavior (particularly for women) or suppressing certain belief systems and lifestyles, these state-imposed restrictions create inequalities that extend well beyond economic inequality in use of space. I argue that discriminatory laws or conventions (especially against women and those whose lifestyles or beliefs are not aligned with the ideals promoted by the state) are translated into unequal power relations in public spaces. This chapter examines how these inequalities impact perceptions of class and culture as social groups interact in public spaces and how public spaces are used to create spaces of being and belonging for marginalized groups.
This chapter investigates the securitisation logic of control animating the AKP’s new securitisation technologies by enumerating the impact of four relevant factors on society: authoritarian lateral surveillance; centralised digital politics; shared contingency governance; and extra-legal and religious over-reach into domestic life. By focusing on these four factors in each section, I argue that under the sway of an authoritarian politics of securitisation, the AKP government combines the technologies of lateral surveillance and centralised digital politics to transgress the principle of individual criminal responsibility in favour of ‘shared responsibility’, a familial ‘sharing in the referent object of securitisation,’ and participation in the maintenance of security. I further suggest that this new development marks a shift away from state of emergency rule to an authoritarian securitisation in which Turkey uses peer-to-peer surveillance pervasively and invasively in the service of state protection.
This chapter opens a series of chapters with case studies on France, the Netherlands, Hungary, and Poland. The institution of French laïcité is commonly understood as referring to a strict separation of church and state. This chapter explains how laïcité has become entangled in the pseudo-constitutional notion of vivre ensemble and the rising significance of social norms for the substantiation of the legal concept of l’ordre public. This is inferred from two particular expressions of constitutional intolerance: first, the overly general and restrictive prohibition of the full-face veil in public spaces, which culminated in the S.A.S. v. France case. Second, it details the expansion of the legal concept of laïcité as expressed in the 2021 Law Concerning the Respect for the Principles of the Republic, which exercises extensive control over the organisation of religious institutions, sources of funding, and their political loyalty to the Republic.
We use an experiment to evaluate the effects of participatory management on firm performance. Participants are randomly assigned roles as managers or workers in firms that generate output via real effort. To identify the causal effect of participation on effort, workers are exogenously assigned to one of the two treatments: one in which the manager implements a compensation scheme unilaterally or another in which the manager cedes control over compensation to the workers who vote to implement a scheme. We find that output is between seven and twelve percentage points higher in participatory firms.
What does it mean for a government to declare its citizens 'dead' while they still live? Following the failed 2016 coup, the Turkish AKP government implemented sweeping powers against some 152,000 of its citizens. These Kanun hükmünde kararnameli ('emergency decreed') were dismissed from their positions and banned for life from public service. With their citizenship rights revoked, Seçkin Sertdemir argues these individuals were rendered into a state of 'civic death'. This study considers how these authoritarian securitisation methods took shape, shedding light on the lived experiences of targeted people. Bringing together approaches from political philosophy, social anthropology, and sociology, Sertdemir outlines the approaches and justifications used by the Turkish government to dismiss opponents, increase surveillance, and brand citizens as 'terrorists'. At the same time, extensive archival research and in-depth interviews bring focus to the impact of these measures on the lives of women, and the disabled and LGBTQ+ communities.
In most scholarly accounts, borders are portrayed simply as thin, jurisdictional lines; they define where one sovereignty ends and a new one begins. Recently, scholars have shown that borders are increasingly becoming wide and zonal – an important advance in our understanding. In this chapter, however, it is suggested that even these accounts are insufficient to change our paradigm as they still rely on the state/territory/border triad as their baseline and see contemporary changes as deviations from this norm. In other words, while such work can generate shifts in our understanding of borders, they nonetheless perpetuate the border’s naturalness. To redress this problem, this chapter begins by defining the “Westphalian” border as it is conventionally understood – distinguishing two features, borders-as-authority and borders-as-control. Second, it looks at the development of modern bordering to locate when this “Westphalian” border starts to take shape. The chapter concludes with a reconceptualization – referred to as the Accordion Model – which captures the conditional and oscillating relationship between states, territories, and borders. The hope is that by doing so, we might chip away at the hegemonic hold that the linear border – and the state/territory/borders triad – has on our political imaginaries
The transnational movement of peoples across the globe is one of the most bitterly contested political issues of our times, eliciting populist anger against migrants and refugees. This public outcry has muffled, however, a more dramatic process: the contemporaneous reconfiguration of territory, rights, and jurisdiction. This chapter highlights the formation of “shifting borders” that enable states to create lawless zones as well as rightless subjects. It then explores a combination of juridical and democratic possibilities for resistance and claims-making in a world of shifting borders and cosmopolitanism without illusions.
