Mainstream human rights activists typically attribute the signature successes of their movement (e.g. antislavery, Gandhi, Martin Luther King) to their uncompromisingly principled stance on behalf of the weak and the exploited. Naming and shaming and ending impunity loom large in their lore. This attitude works well to recruit idealistic activists, but their moralism, legalism, and secular universalism miss the central role of the self-interest of the majority in powering the progress of human rights. A core of idealists has defined aspirational goals, but progress has depended on support from majority mass movements and reform parties that gained power through expedient compromise. The human rights enterprise is now facing fierce pushback from illiberal strongmen and populists who counter-shame the liberal order as decadent, degenerate, and threatening to deeply rooted values. Too often, contemporary rights rhetoric plays into the hands of these illiberal critics. Human Rights for Pragmatists explains how rights-based societies can recover a more accurate narrative of their past pragmatic successes, repair their tactical flaws, and withstand illiberal challenges.

To address vehicle drivetrain vibrations that cause discomfort and poor drivability, this study proposes a new active damping strategy with simple backlash compensation based on the simultaneous perturbation stochastic approximation (SPSA) with norm-limited update vector. First, an experimental device developed for a simplified drivetrain mechanism is demonstrated. A mechanism for reproducing both the contact mode and the backlash mode is included in the device. For the contact mode, a model-based H 2 controller is employed as the baseline damping strategy. Further, to mitigate the backlash effect, a simple algorithm based on mode-switching-based compensation is used with the H 2 controller. In particular, for the critical controller parameters, this article presents a systematic design approach to search for their optimal values. The key parameters, which are needed for the backlash and contact mode controllers, are simultaneously auto-tuned using norm-limited update vector-based SPSA, which ensures the stability in the iterative tuning. The novelty of this study is that both the backlash mode controller and the contact mode controller are simultaneously optimized by the improved version of SPSA, thus realizing a comprehensive auto-tuning design of an active drivetrain damping system. Finally, the active controller is experimentally verified using the actual test device. Comparative studies show that the proposed approach significantly reduces drivetrain vibrations and is robust against fluctuations in the backlash. [ABSTRACT FROM AUTHOR]

This study investigates the problems of eccentricity and backlash using an analytical spur gear model with 26 degrees of freedom (DOF). Previous studies have only investigated the case of eccentricity with a parallel shift of the axis of rotation of the gear relative to its geometric axis of symmetry. This study presents a novel method for determining the radius of eccentricity and its angular position at any distance from the bearing support, in which the axis of rotation and the geometric axis of symmetry of the gear are non-parallel. The effect of gear motion in the line of action (LOA) and off-line of action (OLOA) directions on backlash is precisely determined, despite the fact that most studies usually ignore gear displacement along the OLOA direction. Numerical simulations are performed to determine the effect of eccentricity on backlash, and their results confirm that the proposed method for determining the radius of eccentricity for any eccentricity type is correct. A gear slice model is used for dynamic analysis. Results show that the type of eccentricity has a significant effect on the gear dynamics and that eccentricity analyses have to include other cases than merely eccentricity with parallel axes of gears.

This paper aims to realize multi-objective optimization of cycloid-pin gears to improve the positioning accuracy and load-carrying capacity of the rotary vector (RV) reducer, via the consideration of backlash, transmission error, and torsional stiffness. Initially, the analytical models of the RV transmission backlash and transmission error are developed by using both purely geometrical and equivalent model methods individually. Based on the generalized Hooke's law, a torsion angle model is established to characterize the torsional stiffness of the system, utilizing methods such as Hertzian contact theory and bearing stiffness models. Subsequently, employing the Monte Carlo method, extremum method, and quality loss function, mapping objective functions for dimensional accuracy (tolerance) and transmission performance (backlash, transmission error, and torsional stiffness) are constructed. The geometry dimensions, dimensional accuracy, and modification of the cycloid-pin gear are considered as design variables to create a multi-objective optimization model. The improved Parallel Adaptive Genetic Algorithm using Deferential Evolution (PAGA-DE) is used for multi-objective solutions. Through example calculations, the impact of cycloid-pin gear parameters on transmission performance before and after optimization is determined. The reliability of backlash after optimization within 1.5′ reaches 99.99%, showing an increase of 8.24%. The reliability of transmission error within 1′ reaches 98.52%, demonstrating an increase of 1.35%. The torsional angle is reduced by 8.9% before optimization. The results indicate that the proposed multi-objective optimization design method for cycloid-pin gears can achieve the goal of improving the transmission performance of the RV reducer.

Amid growing polarisation in European societies, civil society elites, encompassing resource-rich, influential and often liberal-oriented civil society organisations (CSOs), are under increased attacks by conservative and progressive actors alike. This article aims to understand who challenges civil society elites, on what grounds, and with what means do they do so in the United Kingdom, by drawing on the cultural theory of frontlash/backlash. The article portrays two ideologically opposed challengers: one coming from within the charity sector in the form of the #CharitySoWhite campaign and another from outside the charity sector led by Conservative MPs, the Common Sense group. While these two challengers are not directly connected, they are part of the broader frontlash/backlash dynamic polarising public debates, with spillover effects in civil society. By applying a frontlash/backlash perspective, the article puts an emphasis on cultural cleavages as one of the central sources of polarisation in the civil space. [ABSTRACT FROM AUTHOR]

In this paper, a novel fuzzy adaptive sliding mode control method is proposed for realizing the asymptotic trajectory tracking of robotic manipulators with control backlash and uncertainties. The fuzzy logic system is introduced into the sliding mode control to estimate the system uncertainties. For compensating the unknown lumped disturbance and accelerating the convergence process, an adaptive super-twisting sliding mode controller is proposed with a novel adaptive law. The system states reach the sliding mode surface in a finite time and the control effect is continuous without over-estimation and control chattering. Depending on the Lyapunov stability theory, the tracking error converges to zero in a fast-exponential form. The effectiveness of the proposed method is fully indicated by the simulation of a robotic manipulator system. [ABSTRACT FROM AUTHOR]

In an increasingly digital Scotland, it is easy to think that generation equal has been achieved. Women make up almost 50% of MSPs at Holyrood, and Scotland has recently had the first woman First Minister. But, increasingly women in public and political life are being put off, turning away, and seeking to leave elected office because of the toll of social media abuse amounting to online violence against women. This paper will explore the concept of online violence against women (OVAW) in the context of women in politics and public life, and against the backdrop of Scottish society. It discusses the challenges, and obstacles of OVAW in Scottish political contexts, not least because of the impact that has been imposed on politically active and prominent women in Scotland. Finally, this paper explores whether the melting pot of misogyny, tempered by a new women-led political class, and facilitated by digital technologies is too much of an ask for women who are already shouldering the expectations and hopes of Scottish society.

In this theoretical article we present our hypothesis on the incompatibility of the inclusive education policy toward students with special educational needs with the meritocratic principle of education. If considering and recognizing the needs of these students is necessary to achieve a successful inclusive environment, we propose that this goal cannot be achieved within current educational systems driven by a meritocratic ideology. We base our rationale on social psychology theories such as system justification and backlash to argue that such incompatibility is particularly visible during the evaluation process. Finally, if we provide some incentives toward greater inclusion while considering the diverse contradictions such inclusivity generates, we also invite researchers to further empirically examine these contradictions in order to guide policy makers within their choices.

A steering control system is one of the key steps in the tractor's automatic navigation. Many nonlinear factors (such as hydraulic dead zone, saturation zone, and mechanical backlash) can dominate the performance of steering control, even the accuracy and stability of tractor navigation. In this study, the Lovol Europa M704-2H tractor was taken as the test platform with the electric steering wheel instead of the onboard steering wheel as the actuator, where the angle sensor on the steering wheel axle of the tractor to measure the size of the wheel turning angle. The steering control system included the steering angle calibration and the steering control. The steering angle calibration aimed to obtain the limit angle and median AD value size of the tractor, and then the steering wheel angle size at any angle by linear fitting. The limit steering angle calibration was required for the tractor steering wheel close to the limit through a circle, the satellite positioning of the trajectory point, and the least squares, in order to obtain the minimum turning radius of the tractor. The two-wheel model of the tractor was then utilized to calculate the maximum steering angle. The median steering angle calibration was required for the tractor to drive a section of an approximate straight-line trajectory. The least squares method (LSM) was also used to identify the correction of the zero position for the accurate median AD value. The TZ-QX2A6/5T front wheel angle meter was selected to compare the front wheel angle with the sensor measurement. The results show that the maximum error of calibrated angle measurement was 1.3°, and the average error was 0.11°, fully meeting the demand of steering control. At the same time, the mechanical backlash of the steering system was firstly quantified, in terms of the angular size of steering wheel reversal across the free travel. The accurate size of mechanical backlash was obtained through experimental identification. Then, the fuzzy PD steering control with backlash compensation was designed at the same time. When the electric steering wheel was out of the free travel, the fuzzy PD control was adopted; when the electric steering wheel was in free travel, the steering control was compensated to add the backlash P control into the output of the fuzzy PD control. Simulation results in Simulink show that better performance was achieved in the tracking of the steering angle signals of square wave and sinusoidal wave, fully meeting the requirements. The fuzzy PD steering control with/without the backlash compensation was also used to compare the tracking performance of square wave and sinusoidal steering angle signals. The experimental results show that the response time of the square wave angle signal tracking without backlash compensation was 1.3 s, where the maximum and average steady-state errors were 0.672°, and 0.244°, respectively. The average delay time of the sine wave angle signal tracking without backlash compensation was 0.5 s, where the maximum and average errors were 2.59° and 1.32°, respectively. Compared to the algorithm without backlash compensation, the time of steering angle error within ±0.2° was improved by 71%, the maximum steady state error was reduced by 0.022°, and the average steady state absolute error was reduced by 0.112°. Once the backlash compensation was performed, the response time of the square wave angle signal tracking was 1.1 s, where the maximum and average steadystate errors were 0.65°, and 0.132°, respectively. The average delay time of the sine wave angle signal tracking was 0.5 s, the maximum and average errors were 1.91° and 1.09°, respectively. Compared to the algorithm without backlash compensation, the maximum error was reduced by 0.68°, and the average error was reduced by 0.23°. The experimental results show that the backlash compensation outstandingly improved the stability of steering control for the less control error. The linear navigation test on the leveled field showed that the maximum and absolute average errors of angle tracking were 2.82° and 0.61°, respectively, when the system was in a steady state. Therefore, better performance was achieved with the high accuracy of the steering control system. [ABSTRACT FROM AUTHOR]

This article uses the theoretical model of 'pushback-backlash' developed by Madsen, Cebulak and Wiebusch (2018) for a comparative analysis of the differing patterns of reaction to the European Court of Human Rights (ECtHR) by two Eastern European countries – Russia, and Poland. We argue that Russian Constitutional Court's (RCC) rejection of ECtHR authority, while extraordinary and legislated by the Duma, was in fact self-limiting, as observed in politically motivated cases. The decisions of the Polish Constitutional Tribunal (PCT), by contrast, go further than pushback, as rights enshrined in the Convention may soon become illusory to Polish citizens. Having chosen a country that was expelled from the Convention (Russia), and one that is still a member (Poland), we suggest opening the conceptual binary between 'pushback' and 'backlash' towards a dynamic continuum.

During activities of daily living (ADLs), the wrist is mainly engaged in positioning and directing the hand. Researches have demonstrated that restoring wrist mobility can significantly enhance the manipulation ability, reduce body distortion caused by motion compensation, and improve the quality of life for amputees. However, most daily activities, particularly the delicate ones, place high demands on the ability of wrist to maintain a certain rotation angle, also known as non-back-drivable ability, which poses a challenge to the design of prosthetic wrists. To address this issue, various solutions have been proposed, including motor holding brakes, high reduction ratio reducers, and worm gears. However, the motor holding brake only functions after a power outage and cannot continuously prevent torque from the load end. The latter two solutions may alter the transmission ratio, resulting in reduced movement speed and transmission efficiency. Therefore, how to design a miniaturized non-back-drivable mechanism without changing the transmission ratio so that the forearm rotational freedom can be locked at any position for any duration is a problem to be solved in the research of prosthetic wrist designs. This paper presents a line-contact based non-back-drivable clutch (NBDC) that does not cause changes in the transmission ratio, ensuring the motion performance of the prosthetic limb. At the same time, it does not introduce additional friction in the forward transmission process, guaranteeing the overall efficiency. Most importantly, it only allows the torque transmitting from the motor to the load, prevents the load reversely from driving back even in a power failure condition, significantly improving the stability, safety, and comfort. Detailed kinematic and static analyses of the working process has been conducted, and transient dynamics simulation has been performed to verify its effectiveness. Through experiments, it is demonstrated that the self-locking torque of the output end could reach approximately 600 Nmm, and the unlocking torque of the input end is about 80 Nmm, which can be effectively integrated in prosthetic wrist rotation joints, contributing to the performance, safety and energy saving of prosthetic joint systems.

Resumo O ciclo menstrual é um fator biológico, e a pessoa que menstrua, mensalmente, necessita de absorventes íntimos, água potável, banheiro adequado e medicações; isso é chamado de boa administração do período. Sua ausência, por questões socioeconômicas, incide no que denominamos pobreza menstrual, contrária à saúde, à vida e à dignidade. Por essa razão, o Legislativo levou à sessão plenária o Programa de Proteção e Promoção da Saúde Menstrual, que não teve objeção dos parlamentares, mas foi vetado parcialmente pelo Poder Executivo, o qual, em sequência, proferiu falas públicas para explicar o veto. Então, indaga-se: há backlash nos discursos que sustentam o veto parcial à Lei n. 14.214/2021, que instituía o Programa de Proteção e Promoção à Saúde Menstrual? A hipótese é de que o Executivo agiu de forma conservadora e contraproducente no que se refere aos direitos das mulheres. Para tanto, esta pesquisa utiliza metodologia descritiva e exploratória, com natureza qualitativa, seguida de análise do discurso presidencial no que tange aos insumos previstos pelo projeto de lei, e, ainda, delimita a categoria epistemológica do conceito de mulher. Conclui-se que há a institucionalização do backlash, já que o discurso define quem pode ter acesso a direitos, o que gera insegurança social para uma questão de saúde pública.

A methodology for analyzing the influence of gear backlash in the axis drive systems of a Cartesian CNC machine on positional accuracy is developed. The approach is based on solving the machine dynamical equations in the context of an angular dead-zone backlash model and an osculating circle approximation of smooth paths in a neighborhood each path turning point, which admit an essentially exact solution for a P controller. This methodology is the basis for schemes to minimize backlash degradation of positional accuracy through feedrate or path geometry modifications, rather than hardware or controller upgrades (that may be expensive or disruptive for CNC machines in continuous production use). As a preliminary demonstration of the methodology, results are presented from the use of smooth feedrate reductions about each path turning point as a means to suppress positional inaccuracies incurred by gear backlash in CNC machine axis drive systems.

Northern Ireland is a case that lets us explore how people respond when deep‐set horizontal inequality is substantively reduced. This article focusses on the reform of horizontal inequality in the cultural sphere and argues that it is likely to be contentious because units and measures are directly related to conflicting constructs of group identity, meaning, and value, and intertwined with conflict over state legitimacy. Northern Ireland shows when and how this becomes politically problematic. The article traces an uneven but largely successful process of economic and political reform, followed by a reversal in the second decade of the 21st century, when unionist unease with cultural equality was reframed into political opposition which at times threatened the stability of the settlement itself. The backlash came when it did because of a confluence of processes: a particularly inappropriate presentation of cultural equality, at a time when the momentum of the peace process was coming to an end, and other opportunities, in particular for the Protestant working class, were closing. The case suggests the need to develop a conception of cultural (in)equality that is attuned to the asymmetric and contested constructions of “groupness” well before backlash occurs.

This paper provides the consequences for trajectory tracking of uncertain n-DOF robotic manipulators in the presence of external disturbances and backlash. The control strategy consists of decoupling system based on inverse dynamics, sliding mode controller, and optimal controller. The tendency of robotic manipulators with gear backlash is to function in two unique phases: contact phase or backlash phase. The sliding mode controller works in the contact phase, after the decoupling of the manipulator, a adaptive second-order sliding mode controller is designed to guarantee system achieve desirable tracking precision and robust stability. The optimal controller works in the backlash phase, which makes the motor quickly traverse the backlash gap and re-contact the joints without collision. Finally, the proposal is verified in simulation using a model of a PUMA560 robot manipulator identified from real data. [ABSTRACT FROM AUTHOR]

Jack Snyder's book Human Rights for Pragmatists: Social Power in Modern Times is less a theory of human rights than a political sociology of liberal modernization. Focusing on that account, this article argues that the story of liberal modernization Snyder's book presents is a distortional fable and, as such, undermines its own claims to pragmatism. This review further contends that this fable of liberal modernization creates a fantasy in which the solution to the problems of contemporary liberal states and the liberal international order is more liberalism. The review concludes by suggesting that any pragmatic account must at least take seriously the possibility that liberalism is part of the problem and, therefore, that it might not be the solution.

We investigated the effects of gender stereotype violations within the context of teaching during the COVID-19 pandemic as well as whether social penalties for violating gender stereotypes in this domain are moderated by trait levels of gender system justification. Participants (N = 254) rated four hypothetical teaching scenarios where target sex (male or female teacher) and reason for refusal to return to in-person teaching (advocating for one's self vs. advocating for others) were manipulated. Results showed that as predicted, participants with high levels of gender system justification rated self-advocating female teachers least favorably. Unexpectedly, participants with low levels of gender system justification rated self-advocating male teachers least favorably. Implications for gender stereotype violation are discussed as well as implications for those teaching during the COVID-19 pandemic. [ABSTRACT FROM AUTHOR]

The dismantling of the Tupac Amaru Neighborhood Organization in Jujuy, Argentina, a major provider of jobs and services, generated limited resistance even among people who had benefited from it. Exploration of the role of counterhegemonic challenges in this process through ethnographic fieldwork, interviews with activists and scholars, newspaper archives, and social movement materials shows that the organization purposefully increased the visibility of stigmatized segments of Jujuy society, defying official narratives about the province. This strategy allowed the organization to recruit members and raise its national profile but also engendered the unified opposition of local elites, which used their control of strategic assets to turn public opinion against activists, portraying them as violent, corrupt, and above all foreign. El desmantelamiento de la Organización vecinal Túpac Amaru en Jujuy, Argentina, un importante proveedor de empleos y servicios, generó una resistencia limitada incluso entre las personas que se habían beneficiado de ella. Una exploración de trabajo de campo etnográfico en torno al papel que jugaron los desafíos contrahegemónicos en este proceso, así como entrevistas con activistas y académicos, y consulta de materiales hemerotécnicos y de movimientos sociales muestra que la organización aumentó deliberadamente la visibilidad de segmentos estigmatizados de la sociedad jujeña, desafiando las narrativas oficiales sobre la provincia. Esta estrategia permitió a la organización reclutar miembros y elevar su perfil nacional, pero también engendró la oposición unificada de las élites locales, que utilizaron su control de activos estratégicos para volver a la opinión pública en contra de los activistas, presentándolos como violentos, corruptos y, sobre todo, foráneos.

Young girls have historically been symbols to be conjured by social movements to garner sympathy for social causes, but are frequently silenced as political agents. This study addresses the celebrification of non-celebrity girls such as Emma González, Greta Thunberg, and Marley Dias and analyzes how backlash politics promote their fame. Some ordinary girls become celebrity activists in part because the trolling and negative media coverage helps propel their visibility, while others enjoy relatively positive experiences with fame. Both of these types of representations of celebrity girl activists - whether fueled by backlash or not -can serve as cautionary tales or as inspiration for girls who wish to engage in activism. Through an intersectional feminist lens, I address the complex social media narratives that emerge about girl empowerment and negotiation of risk - emphasis on self-care and struggle - when girls are famous activists.

Why was the US intervention in Iraq in 2003 and thereafter unsuccessful? Many writers, such as Brendan R. Gallagher, have rightly pointed to the poor US planning and the prior conditions in Iraq. I suggest a third aspect--nationalist resistance to the idea of foreign forces controlling Iraq and denying Iraqis full decision-making autonomy. The heavy US application of military force sparked a backlash which manifested itself in three ways. First, US military intervention in Iraq created or facilitated the growth of actors who are or later become US adversaries. Second, it changed the balance of power in favor of US adversaries and against the United States and its allies. Third, it made the United States government central to the war narratives of some actors. Demonizing or fighting the United States became a rallying cry and a source of recruitment and fundraising.

This work studies on analytical model of the single–stage spur planetary gear in form of lumped–parameter model. It includes key nonlinear factors of planetary gear vibration such as mesh stiffness and backlash of meshing gears. The planetary gear set is modeled as a set of lumped masses and springs and dynamic model of the planetary gear set is presented. Nonlinear equations of motion are presented for each component and each component has three degrees of freedom in planar motion. We have numerically evaluated a set of linear and nonlinear equations to obtain natural frequencies and analysis of vibration behavior of the system under nonlinear factors and fixed output. In previous researches, natural frequencies of planetary gears were evaluated from two points of view: the first one considered fixed output for planetary gears and the second one consists of free rotational output. In this research, the influence of the output flexibility is evaluated on natural frequencies of the planetary gear. Meanwhile, by considering the fixed output, vibration behavior of the nonlinear system is investigated. Results show that the most important effect of the output flexibility is on the principal natural frequency. Because of chaotic phenomenon, vibration behavior of components in translational directions is different.

Despite their complex design, cycloidal gearboxes are characterized by high efficiency. Nevertheless, due to friction, some power is lost during gearbox operation. Basically, these losses occur in two structural nodes: the cycloid gearing and the output mechanism. Since the first of these nodes has been well discussed in the literature, the output mechanism will be discussed in this article. The design of the output mechanism has a significant impact on mechanical power losses. There are several mechanism design solutions. One of them is a mechanism with serially arranged rollers. Three solutions that are different in design but work identically will be discussed. Due to this affinity, a single, common mathematical model will be used to determine the value of losses. As will be shown, the value of losses is directly affected by the backlash, number, and diameter of the rollers used in the output mechanism and indirectly by the ratio and eccentricity of the cycloidal gearbox. Sample calculations were carried out using the developed model of mechanical power losses in the output mechanism. This made it possible to analyze the distribution of backlash created by manufacturing tolerances. It was also shown that the backlash has a significant effect on the number of rollers involved in torque transmission, as well as on the distribution of loads, contact pressures, and mechanical power losses.

Mesmo após décadas de discussão na literatura jurídica, a temática do abortamento conserva seu aspecto polêmico nos meios social e jurídico. Embora a decisão sobre descriminalizar ou não a prática do abortamento geralmente seja tomada pelo Poder Legislativo, por meio de edição de lei formal, observam-se casos em que o Poder Judiciário se posiciona como protagonista diante da questão. O exemplo mais expressivo da última situação é o conteúdo da decisão tomada pela Suprema Corte dos Estados Unidos em 1973, no julgamento do caso Roe vs. Wade, que proibiu a criminalização do abortamento em todo o país até a décima segunda semana de gestação. A literatura jurídica, por seu turno, em várias ocasiões tomou Roe vs. Wade como paradigma para estudos sobre a atuação do Poder Judiciário, como Dworkin (2003) e Sarmento (2005), havendo o alerta, inclusive, para as possíveis consequências que esse papel judicial mais ativo poderia ter sobre os domínios social e político. Ilustrando que a polêmica sobre a questão nunca havia cessado, o precedente criado em Roe vs. Wade foi superado em 2022, com a finalização do julgamento pela Suprema Corte estadunidense do caso Dobbs vs. Jackson Women’s Health Organization. Diante dessas premissas, utilizando-se do método de pesquisa de revisão narrativa de literatura, o presente trabalho objetiva analisar como a atuação do Poder Judiciário na descriminalização do abortamento em Roe vs. Wade pode ter exercido influência para que o próprio precedente fosse derrubado décadas após e, ao cabo, avaliar se o mencionado overruling guarda relação com o chamado efeito backlash.

Under what conditions do citizens consider external sanctions against their country to be appropriate? Based on the literature on blame shifting, we argue that citizens should become less likely to support external sanctions if their government defends itself, especially if it seeks to shift the blame to the external actors (blame effect). However, this effect may be moderated by which actor identifies and claims the norm violation (source effect) and by whether citizens trust their government (trust effect). We test our expectations by conducting a survey experiment on EU sanctions against democratic backsliding in six countries (n = 12,000). Our results corroborate the blame and source effects, but disconfirm the trust effect. These findings have important implications for the literatures on blame shifting and external sanctions as well as for how the EU and other International Organizations should design their sanctioning mechanisms.

Electrophysical agents (EPAs) are core therapeutic interventions in academic physical therapy curricula around the world. They are used concomitantly with several other therapeutic interventions such as exercise, manual therapy techniques, medications, and surgery for the management of a wide variety of soft tissue disorders. Over the past decade, the practice of EPAs has been the subject of intense scrutiny in the U.S. This has been colored by some physical therapists publicly engaging in bashing rhetoric that has yet to be officially and publicly addressed by the guiding organizations which, together, regulate the practice of physical therapy in this country. Published in world renowned public media are unsubstantiated mocking remarks against the practice of EPAs and unethical allegations against its stakeholders. This rhetoric suggests that EPA interventions are "magical" treatments and that those practitioners who include them in their plans of care may be committing fraud. Such bashing rhetoric is in striking contradiction to the APTA's Guide to Physical Therapist Practice 4.0, which lists EPAs as one of its categories of interventions, the CAPTE's program accreditation policy, and the FSBPT's national licensing exam. The purpose of this commentary is to expose the extent of this discourse and to call to action the APTA, CAPTE, and FSBPT organizations, as well as physical therapists, with the aim at putting an end to this rhetoric.

When the first female president of a country is impeached, how does the disgraceful exit shape people's memory of her? Does sexism play a role in such retrospective evaluations? Do the voters who supported her remain loyal, or do they withdraw their support due to disappointment? This article utilizes the impeachment of Park Geun-hye of South Korea as a case to answer these questions. Using a public opinion survey conducted three years after the 2016 impeachment, I demonstrate that hostile sexism played a role in the negative retrospective evaluations of Park, while benevolent sexism did not. Moreover, those who voted for Park in the 2012 presidential election expressed more negative retrospective evaluations of Park than those who did not vote for her, suggesting a backlash effect. Voters who had high expectations of the first female president could experience deep disappointment when the historic first failed to meet their expectations. [ABSTRACT FROM AUTHOR]

Although quotas and other efforts to increase women's political participation can ensure that the descriptive representation of women changes dramatically over a short period of time, it is not clear that social norms and political interests can shift as quickly as the distribution of legislative seats. Rather than being interpreted as a move toward a more pluralistic and representative form of government, the increased number of women in office may represent a threat to those who benefit from the status quo, and their resistance to losing their privilege may manifest in myriad forms of discrimination and violence. The relationship between political violence targeting women and increasing numbers of women in politics is often overlooked, despite the recognized potential for "backlash" against women's empowerment initiatives. This article leverages data from the Armed Conflict Location & Event Data Project (ACLED) to explore the impact of increasing numbers of women in government on violence targeting women in Kenya. The findings show that rates of political violence targeting women have risen in tandem with the share of seats held by women in the lower chamber. That increasing women's representation in political office may result in violent backlash against women generally should prompt greater attention from policymakers and academics to patriarchal resistance to women's advancement.

In this paper the analysis of backlash influence on the spectrum of torque at the output shaft of a cycloidal gearbox has been performed. The model of the single stage cycloidal gearbox was designed in the MSC Adams. The analysis for the excitation with the torque and the analysis with constant angular velocity of the input shaft were performed. For these analyses, the amplitude spectrums of the output torque for different backlashes was solved using FFT algorithm. The amplitude spectrums of the combined sine functions composed of the impact to impact times between the cycloidal wheel and the external sleeves were computed for verification. The performed studies show, that the backlash has significant influence on the output torque amplitude spectrum. Unfortunately the dependencies between the components of the spectrum and the backlash could not be expressed by linear equations, when vibrations of the output torque in the range of (350 Hz – 600 Hz) are considered. The gradual dependence can be found in the spectrum determined for the combined sine functions with half-periods equal impact-to-impact times. The spectrum is narrower for high values of backlash.

We examined whether female leaders would be evaluated less favorably compared to male leaders regarding workplace bullying. Previous research has demonstrated that women violating prescriptive gender norms of communality experience backlash, and that female leaders are stereotyped of having a communality deficit. Building on that, we hypothesized (1) more moral outrage against and (2) more intentions to punish a female leader compared to a male leader. We further hypothesized (3) the accusations of workplace bullying against a female leader were going to be judged as more accurate than against a male leader. Further, defendants that stereotypically fit to the crime they are accused of were found to be judged guilty more often. So, we assumed, (4) a suspected bully that is a female leader was going to be judged as less credible, while (2) the suspected victim of a female leader bully was going to be judged as more credible compared to a male leader. Participants (N = 202) read a workplace bullying scenario with a female employee accusing either a female or a male leader of bullying. No effect of gender of suspected bully was found for moral outrage measures, punishment intention judgments, and credibility judgments. Contrary to our predictions, participants found the accusations against the male leader significantly more accurate than against the female leader. Gender and sex-role scores of participants were found to be linked to judgments. Implications for future research are discussed.

Conversations about work-family conflict are commonplace. However, most of the conversation is based on how individuals can best manage work and family demands. Little is known about how others perceive and react towards individuals who go through this experience. Building on theories of social evaluation and stereotype maintenance, we hypothesized that due to gender stereotypes, which prescribe the ideal woman as highly invested in family and the ideal man as highly invested in work, women who experience work interference with family (WIF) and men who experience family interference with work (FIW) would elicit negative reactions. Results of three experimental studies (NStudy1 = 569; NStudy2 = 299; NStudy3 = 275) and a field study (N = 219) provided only limited evidence for this assumption. However, they consistently showed across all four studies that both men and women who experience FIW were systematically judged and treated less favourably compared to employees with WIF, by observers and their supervisors, on several work-related dimensions (agency, dominance, respect, promotability, work performance, reward allocations). However, they were judged to be the better parents. We discuss the implications of our findings for work-family conflict research. [ABSTRACT FROM AUTHOR]

Given feminist backlash and stigma in society, whether people would publicly say that they are a feminist might depend on their social context, which could have implications for understanding who identifies as a feminist and why, as well as community and coalition-building. We therefore tested whether disclosure of feminist identity varies across interaction contexts and by gender/sex, given some gender/sex-specificities to stigma about feminist identity. In our study, we asked women, men, and nonbinary people who are feminists (N = 640) about their willingness to disclose their feminist identity in eight interaction contexts: immediate family, extended family, friends, partners, work, strangers, anti-feminists, and pro-feminists. Results revealed substantial intra-person contextual variability in feminist identity disclosure, suggesting participants' decision to disclose their feminist identity varies across contexts. In general, participants were most reluctant to disclose their feminist identity to a stranger, with anti-feminists and work contexts showing the next greatest likelihood to not disclose. Finally, participants were most likely to share their feminist identity with their immediate family, friends, pro-feminist, and romantic partners. We also examined the disclosure pattern for each gender/sex group (women, men, and nonbinary participants). Results emphasize that holding a feminist identity might not necessarily lead to identity disclosure and that disclosure decisions may depend on contextual pressure and gender/sex considerations.

Before the onset of COVID-19, the political mood in Europe shifted to the right. This is indicated, for example, by efforts to close the borders to migrants, an undermining of legislative and executive democratic structures as well as restrictions on free speech. Such anti-democratic developments have also impacted gender equality – at the level of policy and in daily life. Our paper aims to examine the policies on gender equality of the center-right Austrian government from 2017 to 2019 and their influence on feminist organizing. Applying a participatory, action-based research approach in the context of a neoliberal conservative nation state, the data shows a clear backtrack from a pluralist perspective of gender equality policies and regression towards heteronormativity, complemented by a focus on the gender binary that discounts the social construction of gender. These trends clearly influence feminist organizing. [ABSTRACT FROM AUTHOR]

In order to improve the state monitoring and adaptive control capability of inertial stabilization platforms (ISPs) with unknown loads, it is necessary to estimate the dynamic parameters comprehensively online. However, most current online estimation methods regard the system as a linear dual-inertia model which neglects the backlash and nonlinear friction torque. It reduces the accuracy of the model and leads to incomplete and low accuracy of the estimated parameters. The purpose of this research is to achieve a comprehensive and accurate online estimation of multiple parameters of ISPs and lay a foundation for state monitoring and adaptive control of ISPs. First, a dual-inertia model containing backlash and nonlinear friction torque of the motor and load is established. Then, the auto-regressive moving average (ARMA) model of the motor and load is established by the forward Euler method, which clearly expresses the online identification formula of the parameters. On this basis, the adaptive identification method based on the recursive extended least squares (RELS) algorithm is used to realize the online estimation of multiple parameters. The simulation and experimental results show that the proposed adaptive multi-parameter estimation method can realize the simultaneous online identification of the moment of inertia of the load, the damping coefficient of motor and load, the transmission stiffness, the Coulomb friction torque of motor and load, and the backlash, and the steady-state error is less than 10%. Compared with the traditional linear dual-inertia model, the similarity between the model based on the proposed adaptive parameter estimation algorithm and the actual system is increased by 65.3%.

Research suggests that White women often experience more gender backlash than women of color in response to expressions of agency. We consider whether this differential in backlash is driven by the match or mismatch of the race of both perceivers and targets. Much of the existing work in this space examines the perspective of White perceivers, which might underestimate racial minority women's susceptibility to backlash if backlash occurs primarily in same-race interactions. We examine how the racial group memberships of targets and perceivers jointly affect backlash against gender-norm violating women. In analyses of Dr. Christine Blasey-Ford's accusations of sexual assault against Brett Kavanaugh and Anita Hill's accusations against Clarence Thomas during their respective U.S. Supreme Court confirmation hearings, an archival analysis of the 2016 U.S. presidential election, and two experiments, we find that perceivers of different races tend to express more backlash toward racial in-group than out-group women.

This paper focuses on the public debate in Poland and Italy concerning the right to abortion in the contemporary rise of populist neo-conservative forces in Europe and of a global feminist movement. In both countries, the historical Catholic interference into women's reproductive rights and self-determination has been enforced by the renewed alliance of right-wing governments and pro-life groups to converge into a transnational “anti-gender war”. This represents a real backlash against women’s achievements over the last decades in terms of reproductive and sexual citizenship, which appears to be the battlefield for redefinition of western citizenship in times of global crisis. Although different genealogies, we identified a common framing of neo-conservative discourse, and of feminist claims and practices, as that of feminist strikes and social mutualism. In this perspective, we consider these practices as a normativity from below, arguing that feminist movement is addressing a new paradigm of citizenship.

This paper aims to realize multi-objective optimization of cycloid-pin gears to improve the positioning accuracy and load-carrying capacity of the rotary vector (RV) reducer, via the consideration of backlash, transmission error, and torsional stiffness. Initially, the analytical models of the RV transmission backlash and transmission error are developed by using both purely geometrical and equivalent model methods individually. Based on the generalized Hooke’s law, a torsion angle model is established to characterize the torsional stiffness of the system, utilizing methods such as Hertzian contact theory and bearing stiffness models. Subsequently, employing the Monte Carlo method, extremum method, and quality loss function, mapping objective functions for dimensional accuracy (tolerance) and transmission performance (backlash, transmission error, and torsional stiffness) are constructed. The geometry dimensions, dimensional accuracy, and modification of the cycloid-pin gear are considered as design variables to create a multi-objective optimization model. The improved Parallel Adaptive Genetic Algorithm using Deferential Evolution (PAGA-DE) is used for multi-objective solutions. Through example calculations, the impact of cycloid-pin gear parameters on transmission performance before and after optimization is determined. The reliability of backlash after optimization within 1.5′ reaches 99.99%, showing an increase of 8.24%. The reliability of transmission error within 1′ reaches 98.52%, demonstrating an increase of 1.35%. The torsional angle is reduced by 8.9% before optimization. The results indicate that the proposed multi-objective optimization design method for cycloid-pin gears can achieve the goal of improving the transmission performance of the RV reducer.
