This article establishes the role white women played in shaping the urban labor force and the economy in late colonial times in Lima, roughly from 1790 to 1822. It focuses on the impoverished elite women who, by the end of the colonial period, had to ask for alms to avoid working with their own hands. An important part of the Limeño elites could not respond to the twofold challenge: the negative consequences of the economic and administrative reforms of the Bourbons, and the relative flexibilization of the social order in Lima by the end of the eighteenth century. Instead of adapting to new conditions, the Spanish elites generated a social discourse that reaffirmed status and ethnicity as a means to distinguish themselves from the “vicious” plebeian sectors. More than one thousand applications to Church relief programs serve as the main foundation of this article; they are made up of at least one fifth of the white female population of the city in 1806. The article enters into dialogue with studies on socio-labor practices and the history of gender and ethnicity by engaging with concrete experiences of poor elite women in a city considered to be the opulent center of the Spanish colonial power.

Collaborative robotics is a field of growing industrial interest, within which understanding the energetic behavior of manipulators is essential. In this work, we present the electro-mechanical modeling of the UR5 e-series robot through the identification of its dynamics and electrical parameters. By means of the identified robot model, it is then possible to compute and optimize the energy consumption of the robot during prescribed trajectories. The proposed model is derived from data acquired from the robot controller during bespoke experimental tests, using model identification procedures and datasheet provided by manipulator, motors, and gearbox manufacturers. The entire procedure does not require the use of any additional sensor, so it can be easily replicated with an off-the-shelf manipulator, and applied to other robots of the same family.

The “Niu–Li Factional Strife,” named after Niu Sengru (779–847) and Li Deyu (787–850), is an enduring theme in Tang history. Based on accounts of personal animosity, a narrative evolved in which Niu and Li have become the ringleaders of two factions that drew in almost all high-profile literati of the ninth century. This article revises traditional and modern narratives of the Strife by first showing that the scattered and contradictory evidence in the earliest sources does not bear out the model of a decades-long struggle between two factions. Second, it demonstrates how “Niu and Li” first arose as an emblem of Tang weakness and a rallying cry for unity within the bureaucracy under the Northern Song two centuries later. Finally, it shows how modern historians picked up the loose ends and remoulded them into a struggle between different classes against the backdrop of factious politics in Republican China.

In nineteenth-century Britain, captive snakes in menageries and zoological gardens were routinely fed with live prey – primarily rabbits, pigeons and guinea pigs. From the late 1860s, this practice began to generate opposition on animal welfare grounds, leading to a protracted debate over its necessity, visibility and morality. Focusing on the c.1870–1914 period, when the snake-feeding controversy reached its zenith, this article charts changing attitudes towards the treatment of reptiles in captivity and asks why an apparently niche practice generated so much interest. By looking at the biological arguments put forward for and against live feeding, the article traces the changing nature of humanitarian activism in the late nineteenth century and shows how the shifting character of the live-feeding debate paralleled wider trends in the animal welfare movement. It also highlights the different types of knowledge and expertise involved in the debate, as naturalists, veterinary surgeons, legal professionals, zookeepers and humanitarians offered conflicting perspectives on questions of reptilian dietary requirements and animal sentience.

Finite Cartesian products of operators play a central role in monotone operator theory and its applications. Extending such products to arbitrary families of operators acting on different Hilbert spaces is an open problem, which we address by introducing the Hilbert direct integral of a family of monotone operators. The properties of this construct are studied, and conditions under which the direct integral inherits the properties of the factor operators are provided. The question of determining whether the Hilbert direct integral of a family of subdifferentials of convex functions is itself a subdifferential leads us to introducing the Hilbert direct integral of a family of functions. We establish explicit expressions for evaluating the Legendre conjugate, subdifferential, recession function, Moreau envelope, and proximity operator of such integrals. Next, we propose a duality framework for monotone inclusion problems involving integrals of linearly composed monotone operators and show its pertinence toward the development of numerical solution methods. Applications to inclusion and variational problems are discussed.

The main interpretative claims in the chapter on Kant’s critique of the ontological argument in Ian Proops’s The Fiery Test of Critique are critically discussed.

Drawing on theories of comparative regionalism, this article examines the construction of regionalist frames in Azerbaijan covering the period from 1993 to mid-2023. By examining more than 60 text passages from presidential speeches and statements, the study identifies two framings of regionalism that have dominated presidential discourses in Azerbaijan: the discourse of Turkic solidarity or unity (in the political-security domain) and the narrative of an East-West corridor or the revival of the Silk Road for transport of cargo and hydrocarbon resources (in the economic domain). By constructing these discursive frames, Azerbaijani state leaders crafted an alternative regional order reconstituting the geographic category of “South Caucasus” into a new, spatially broader area. In this formulation, “South Caucasus” is viewed as a central pillar of the Silk Road, and Azerbaijan as one of its focal points or nodes. While the study underscores a key role that actors and ideas play in the formation of regions and regional institutions, it also highlights how social construction of regional identities is embedded in and shaped by historical experiences and country-specific political-economic conditions such as historical memories, experiences of war, collective identities and cultural affinities, geographic location, domestic political economic structures, and international linkages.

The tropical analogue of the lemma on the logarithmic derivative is generalised for noncontinuous tropical meromorphic functions, that is, piecewise linear functions that may have discontinuities. In addition, two Borel type results are generalised for piecewise continuous functions. With the generalisation of the tropical analogue of the lemma on the logarithmic derivative, several tropical analogues of Clunie and Mohon’ko type results are also automatically generalised for noncontinuous tropical meromorphic functions.

Debate regarding the continuity of Cypriot political forms from the Late Bronze Age to the Cypro-Archaic is persistent, resulting in a scholarly divide with few signs of resolution. This article reviews the historiography of political forms proposed for Cyprus as the essential context for this debate. It considers several major themes that emerge from the debate: the use of anthropological models for state formation, regionalism, social networks, and the nature of spatial power. The author views the debate as centred on two equally valid motivations: using related social science theory to enhance archaeological explanation and emphasizing Cypriot autonomy. These motivations need not be set in opposition but, together, illustrate the island's unique history and provide the basis for vibrant scholarship.

We demonstrate that a large class of discrete choice models of demand can be approximated by real analytic demand models. We obtain this result by combining (i) a novel real analytic property of the mixed logit and the mixed probit models with any distribution of random coefficients and (ii) an approximation property of finite mixtures of Gumbel and Gaussian distributions. To illustrate some of the implications of this result, we discuss how real analyticity facilitates nonparametric and semi-nonparametric identification, extrapolation to hypothetical counterfactuals, numerical implementation of demand inverses, and numerical implementation of the maximum likelihood estimator.

On the report model of appreciating fiction, one imagines learning about a fictional world through a report: reading or viewing someone’s account or listening to them tell their story. On the transparency model, one simply imagines the things that are fictional in the story, without imagining anything about how that information is acquired. It is argued that the transparency model is the default, in literature and cinema, but in comics, it is the report model that is the default.

As the largest and most comprehensive Chinese database in the world, China National Knowledge Infrastructure (CNKI: Zhong guo zhi shi ji chu she shi gong cheng 中国知识基础设施工程, also commonly known as Zhi wang 知网)1 is supervised by Tsinghua University and Tonfang Knowledge Network (TKN), a high-tech enterprise funded by Tsinghua University in 1997. It is supported by the Chinese Ministry of Education, the Publicity Department of the Communist Party of China, the Ministry of Science and Technology, the State Administration of the Press, Publication, Radio, Film and Television of the People's Republic of China and the State Planning Commission of the PRC. In December 1996, CNKI began providing CD-ROM and CAJ-CD for Chinese academic journals, and it was officially launched in 1999. This repository initially focused on Chinese academic journals and later expanded its coverage to PhD dissertations, masters’ theses, conference proceedings, yearbooks, books and patent documents. It is divided into three categories: ‘databases’, ‘specialized sources’, and ‘international sources’, including ProQuest and Taylor and Francis journal databases. Ten service centres are established across the world, including Beijing, North America, Japan, Korea, Taiwan and Hong Kong; users include universities, research institutions, government think tanks, industries, hospitals and public libraries.2 CNKI (or CIKRD) updates its information on a daily basis, and its current growth rate is approximately 350,000 new journal articles per month.

Resonant Bessel-beam launchers (BBLs)are radiating devices constituted by a cylindrical metallic cavity with a partially reflecting sheet (PRS) on top. Millimeter-wave resonant BBLs typically exhibit transverse magnetic (TM) polarization due to the use of coaxial probes as feeders and homogenized metasurfaces as PRS. Launchers showing either a purely transverse electric (TE) or a hybrid (quasi-TE) polarization have recently been proposed for realizing wireless power transfer (WPT) links in the radiative near-field region at millimeter waves. The former are obtained by means of a radial slot array as a feeder and a homogenized metasurface as a PRS. The latter are obtained by using a loop antenna as a feeder and an annular strip grating in the homogenization limit as radiating aperture. In this work, based on an original semi-analytical model, such a metasurface is demonstrated to show a dichroic behavior. This interpretation explains the improvement in terms of polarization purity with respect to more nondichroic conventional homogenized metasurfaces. The behavior of the annular strip grating under a pure TM polarization is tested with a coaxial feeder, whereas its behavior under a pure TE polarization is tested by means of the radial slot array feeder. Results confirm the validity of the proposed analysis, which is finally exploited to evaluate the WPT performance.

Runway overruns (ROs) are the result of an aircraft rolling beyond the end of a runway, which is one of the accident’s types that most frequently occurs on aviation. The risk of an RO arises from the synergistic effect among its precursors, such as unstable approaches, long touchdowns and inadequate use of deceleration devices. To analyse this complex socio-technical system, the current work proposes a customised functional resonance analysis method, called FRAM-FDM, as traditional techniques of risk and safety assessment do not identify the interactions and couplings between the various functional aspects of the system itself, especially regarding human and organisational components. Basically, FRAM-FDM is the coupling of a traditional FRAM with flight data monitoring (FDM) techniques, used here to quantify the variabilities of the flight crew performance while executing the required activity (i.e. the landing). In this proposal, these variabilities (i.e. the FRAM functions aspects) are aggregated by the addend of a logistic regression, resulting in a model to evaluate the flare operations and the brake application profile effect on the remaining distance to the end of the runway, used as a reference to classify the landing as acceptable or not. The present application of the FRAM-FDM assesses the operational risk of a sample fleet in overrunning the runway during landing, highlighting the brake pedal application profile as the most relevant contributor. The model improves the knowledge about the system behaviour, being useful to direct flight crew training.
