The eighteenth century is often thought of as an important era for the secularization of British philosophy. One dimension of this secularization involves philosophers developing theories that, while not explicitly rejecting God, are less reliant on claims about God for their intelligibility and plausibility. A comparison of Adam Smith with his teacher, Francis Hutcheson, reveals an underappreciated facet of this process. Hutcheson portrayed God as an impartial legislator and used this metaphor to clarify contested moral rules in a way that would make little sense if God did not exist. In contrast, Smith's impartial spectator does not require belief in a God who is the author of the moral law in order to determine the correct interpretation of contested moral principles. By pursuing this alternative conception of impartiality, Smith developed a theory that was, in this respect, less reliant on religious premises than Hutcheson's had been.

La qualité des soins apportés aux personnes vivant avec la maladie d’Alzheimer (MA) dépend en partie de la capacité des professionnels à déterminer le degré de conscience de la maladie chez les patients. La présente recherche s’est intéressée aux représentations des soignants concernant la conscience des troubles chez les résidents d’établissements de soins de longue durée présentant un diagnostic de MA. Le pouvoir prédicteur de l’anosognosie sur le fardeau soignant a également été examiné. L’anosognosie des troubles de la construction (r = 0,40, p = 0,0164) et de l’initiation (r = 0,32, p = 0,052) était corrélée au fardeau soignant. Les professionnels se représentaient les résidents comme ayant une conscience altérée de leurs capacités, même en l’absence d’anosognosie. Les scores réels d’anosognosie ne prédisaient pas les estimations soignantes, hormis le score global sous forme de tendance (χ2 = 3,38, p = 0,066). Les soignants surestimaient pourtant les performances cognitives des résidents, telles que mesurées au moyen du protocole Misawareness (prédictions aidants/performances réelles : DC = 12,32, p < 0,0001).

As regional chronologies become better defined, we are better able to track large-scale population movements and related cultural change. A dataset of 156 radiocarbon dates from the Middle Cumberland Region (MCR), evaluated with 199 more dates from the Ridge and Valley portions of northern Georgia and East Tennessee, enable modeling of population movements from the Central Mississippi Valley into the MCR, as well as subsequent movements and effects in the Ridge and Valley between AD 1200 and 1450. The dissolution of Cahokia is of particular interest, because the MCR falls geographically between the American Bottom and the Ridge and Valley province. This large-scale chronological perspective places key events in this part of the Southeast and Midwest into a unified historical framework that increases our understanding of the timing of cultural events. A related goal is to sort out possible external events and influences that may have affected this large region. This study makes apparent the relationships between cultural events and natural events, such as the drought sequences reported for the Central Mississippi Valley and beyond.

In recent years US prisons have failed to meet legally required minimum standards of care and protection of incarcerated people. Explanations for the failure to protect prisoners in the United States focus on the effects of the Prison Litigation Reform Act (PLRA) and lack of adequate external oversight. However, very little scholarship empirically examines how different systems of accountability for prisoners’ rights work (or do not work) together. In this article, we introduce an accountability framework that helps us examine the prisoners’ rights “accountability environment” in the United States. We then compare two post-PLRA case studies of failure to protect incarcerated women from sexual assault in two different states. We find that the prisoners’ rights accountability environment is a patchwork of legal, bureaucratic, professional, and political systems. The patchwork accountability environment consists of a web of hierarchical and interdependent relationships that constrain or enable accountability. We argue that ultimately the effectiveness of prisoners’ rights accountability environments depends on whether protecting prisoners’ rights aligns with the priorities of dominant political officials. Our argument has implications for efforts to improve prison conditions and incarcerated people’s well-being.

Closed-loop kinematics of a dual-arm robot (DAR) often induces motion conflict. Control formulation is increasingly difficult in face of actuator failures. This article presents a new approach for fault-tolerant control of DARs based on advanced sliding mode control. A comprehensive fractional-order model is proposed taking nonlinear viscous and viscoelastic friction at the joints into account. Using integral fast terminal sliding mode control and fractional calculus, we develop two robust controllers for robots subject to motor faults, parametric uncertainties, and disturbances. Their merits rest with their strong robustness, speedy finite-time convergence, shortened reaching phase, and flexible selection of derivative orders. To avoid the need for full knowledge of faults, robot parameters, and disturbances, two versions of the proposed approach, namely adaptive integral fractional-order fast terminal sliding mode control, are developed. Here, an adaptation mechanism is equipped for estimating a common representative of individual uncertainties. Simulation and experiment are provided along with an extensive comparison with existing approaches. The results demonstrate the superiority of the proposed control technique. The robot performs well the tasks with better responses (e.g., with settling time reduced by at least 16%).

This article contributes to the hitherto limited scholarship on the Chinese federalist movement in the 1910s and 1920s by conducting a thorough investigation of its ideological underpinnings and political blueprints. It compares the federalist ideas, plans, and activism of three thinkers—Zhang Taiyan, Zhang Shizhao, and Chen Jiongming—who stood firmly against the centralist trajectory of state-building in China after 1911 and advocated the formation of a Chinese federation. It argues that Chinese federalists, instead of emulating Western models, critically engaged with a broad spectrum of ideologies—Daoism, Buddhism, social Darwinism, parliamentarianism, guild socialism, anarchism etc.—when formulating their federalist agendas. Emphasizing the Chinese tradition of self-government, which underwent reinterpretations during the late Qing and early Republican periods, this article examines the extent to which Chinese federalism presented an alternative to Western political modernity.

A system-in-package for a wideband digital radar, in D-band, requires broadband, high-gain antennas combined with broadband chip-to-package and package-to-printed circuit board (PCB) interconnects. This paper demonstrates a wideband, low-loss quasi-coaxial signal transition, and a novel electric split ring resonator (eSRR)-based antenna-in-package (AiP) with a modified reflector concept, for improved gain, in embedded wafer level ball grid array (eWLB) technology. A complete chip-to-package-to-PCB interconnect is also demonstrated by combining the quasi-coaxial transition with a chip-to-package interconnect. The quasi-coaxial signal transition has the largest impedance bandwidth among ball grid array-based quasi-coaxial signal transitions. For the modified reflector concept, a horn-shaped cavity is micromachined in the PCB substrate and remetallized with aerosol-jet printing, placing the reflector 0.25λ from the antenna. The antenna gain is improved with up to 5.3 dB. The AiP with the horn-shaped reflector is the single element with the highest gain, in eWLB technology, above 100 GHz.

This paper systematically investigates a soft-rigid hybrid pneumatic actuator (SRHPA), which consists of a rigid-foldable twisting skeleton capable of a large range of helical motion and a soft bellows muscle with high linear driving force. Considering the unique varying-pitch helical motion of the foldable skeleton, the analytical model mapping the input force generated by the bellows muscle and output forces of the actuator is revealed and verified with a simulation of the force analysis. Prototypes of the actuator are developed by fabricating the twisting skeleton with multilayered aluminum composite panels and 3D-printing the bellows muscle with thermoplastic polyurethane (TPU) 95A filament. The static and dynamic performances of the prototypes are tested to validate the analytical modeling of output forces. Using the actuator as a module, a novel bipedal inchworm robot with four modules is developed and tested to demonstrate its adaptability in confined space by switching between the going-straight, the turning-around, and the rotating gaits. The hybrid actuator and the inchworm robot with zero onboard electronics have the potential to be deployed in extreme environments where pneumatically actuated systems are preferred over electrical machines and drives, such as in nuclear and explosive environments.

In examining wares discovered from the cultures of Sanxingdui and Jinsha and from the former site of the ancient kingdom of Dian in Sichuan and Yunnan provinces, this article highlights a number of shared features and trends that suggest a continued artistic, technological and cultural transmission through time and space. The article aims to supplement established theories on the rich material culture of this region. It will look in particular at the development of its striking bronze metallurgy, largely deriving from the established traditions of the Yellow River valley in China’s Bronze Age. It highlights the function of a dense network of trading routes, referred to in modern scholarship as the “Southwest Silk Road”, as an important facilitator of cultural and artistic exchange and reciprocation from ancient times.

In this paper, we introduce a compact 6 × 8 channel multiple-input multiple-output frequency-modulated continuous-wave radar system capable of determining the three-dimensional positions of targets despite utilizing a linear virtual array. The compact system, containing two cascaded radar transceiver ICs, has 48 virtual channels. We conduct a direction of arrival estimation with these virtual channels to determine the azimuth angle. To overcome the spatial limitation of the linear array, we use frequency-steered transmit antennas, which vary their main lobe direction during the frequency chirp, allowing the elevation angle to be determined by using a sliding window fast Fourier transform algorithm. In this study, we present the system’s concept along with the associated signal processing. By taking measurements in different scenarios, each with differently placed corner reflectors, we investigate the capability of the system to separate adjacent targets concerning range, azimuth, and elevation. These measurements are additionally employed to point out the design trade-offs inherent to the system.

The article analyzes the contemporary material, political, and symbolic construction of Hamburg's free port, zooming in on its festive opening in 1888, when Kaiser Wilhelm II visited to perform this ceremonious act. Asking why the “Speicherstadt” (warehouse city) was right away dubbed a “city” even though this was an exclusively commercial space devoid of inhabitants, the article uses this case study to argue that process concepts like “urbanization” frame our perspectives in ways that eclipse how older ideas about urbanity still defined a late-nineteenth-century political imaginary. The article shows how the opening ceremony, staged as an imperial adventus, alongside the “Speicherstadt's” neo-Gothic red-brick architecture, made recourse to established cultural forms that historians and other commentators often deem premodern. To counteract the prospect that port expansion could turn Hamburg into a working-class city, Hamburg's bourgeois merchant elite tried to construct the free port as a global urban bourgeois space embodying the city's history and its longevity as a space of urban trade privilege. The latter had erstwhile been defined by Hamburg's city walls, which, as the article argues, were symbolically rebuilt in the form of the Speicherstadt. The latter was the “city” into which this modern-day imperial adventus led.
