Everyday understanding takes empathy to be not just emotional mirroring with a specific etiology, but also a form of feeling for, or on behalf of, another. This article proposes an analysis of that for-relation. The analysis begins with the phenomenon of acting on behalf, which is then used as a template for an analysis of generic on behalfness, applicable to both action and emotion. The key to the relation turns out to be an agent’s espousal of a target’s goal, in light of which the agent acquires reasons for acting or feeling.
We present a method for reconstructing evolutionary trees from high-dimensional data, with a specific application to bird song spectrograms. We address the challenge of inferring phylogenetic relationships from phenotypic traits, like vocalizations, without predefined acoustic properties. Our approach combines two main components: Poincaré embeddings for dimensionality reduction and distance computation, and the neighbour-joining algorithm for tree reconstruction. Unlike previous work, we employ Siamese networks to learn embeddings from only leaf node samples of the latent tree. We demonstrate our method’s effectiveness on both synthetic data and spectrograms from six species of finches.
We explore the drawing of an axisymmetric viscoelastic tube subject to inertial and surface tension effects. We adopt the Giesekus constitutive model and derive asymptotic long-wave equations for weakly viscoelastic effects. Intuitively, one might imagine that the elastic stresses should act to prevent hole closure during the drawing process. Surprisingly, our results show that the hole closure at the take-up point is enhanced by elastic effects for most parameter values. However, the opposite is true if the tube has a sufficiently large hole size at the inlet nozzle of the device or if the axial stretching is sufficiently weak. We explain the physical mechanism underlying this phenomenon by examining how the second normal stress difference induced by elastic effects modifies the hole evolution process. We also determine how viscoelasticity affects the stability of the drawing process and show that elastic effects are always destabilising for negligible inertia. On the other hand, our results show that if the inertia is non-zero, elastic effects can be either stabilising or destabilising depending on the parameters.
Accurate absorption analysis of metasurface absorbers, considering all reflected modes, is critical. This corrigendum addresses a significant error in recent papers [19 and 20] as two selected samples, which misinterpret absorption mechanisms by neglecting the main contribution of cross-polarized reflections. According to the review of highly authoritative and highly referenced research, metasurface absorbers with losses can achieve wideband absorption, while low-loss structures typically exhibit resonant narrowband absorption or convert incident power to cross-polarized reflections – an aspect overlooked in [19 and 20]. We present key principles for accurate simulation in HFSS software, emphasizing correct handling of symmetrical and asymmetrical meta-cells and determining all reflected components. Re-analysis of the designs in [19 and 20] using these simulation principles reveals a significant overestimation of reported absorption; they are, in fact, polarization converters rather than perfect absorbers. Finally, we propose potential recommendations for these designs without using a loss mechanism.
If G is a graph, then $X\subseteq V(G)$ is a general position set if for every two vertices $v,u\in X$ and every shortest $(u,v)$-path P, no inner vertex of P lies in X. We propose three algorithms to compute a largest general position set in G: an integer linear programming algorithm, a genetic algorithm and a simulated annealing algorithm. These approaches are supported by examples from different areas of graph theory.
Russian nation-building policy has often been described as ambiguous, blending a rhetorical commitment to the state’s multinational character together with more exclusionary rhetoric and policies. Drawing from original survey questions on national identity commissioned in December 2022, I find that Russian citizens continue to endorse a multinational vision of the Russian state during wartime. Respondents are simultaneously likely to exclude minorities from being fully considered as “true Rossians” [istinnye rossiiane], while socioeconomic and political factors are meaningfully associated with these patterns. In line with previous scholarship, these findings underscore the blurriness of the russkii/rossiiskii distinction in practice: just as russkii should not always be interpreted as an exclusively ethnic term, rossiiskii should not be seen as a non-ethnic category, either. The findings in the Russian case carry implications for understanding how nation-builders in multiethnic contexts may seek to cater to ethnic majorities while simultaneously signaling commitments to ethnic diversity.
We investigate the motion of weakly negatively buoyant spheres settling in surface gravity waves using laboratory experiments. The trajectories of the settling spheres are tracked over most of the water depth with simultaneous measurements of the background fluid flow. These experiments are conducted in the regime relevant for environmental and geophysical applications where both particle inertia and fluid inertia are important. Using these data, we show that the sphere motion is well described by the kinematic sum of the undisturbed fluid velocity and the particle terminal settling velocity as long as the fluid inertia is not too large. We show how this result can be understood in the context of an ad hoc Maxey–Riley–Gatignol-type equation where the drag on the particle is given by the Schiller–Naumann drag correlation. We also evaluate whether inertial particles experience enhanced settling in waves, finding that measurement uncertainties in the particle terminal settling velocity and the presence of Eulerian-mean flows do not allow the small percentage increase in the settling velocity to be measured. When the fluid inertia becomes large enough, we observe path instabilities caused by particle wake effects in both quiescent and wavy conditions. However, the particle velocity fluctuations associated with the path instabilities are unaffected by the background flow. The minimal influence of the wavy flow on the particle path instabilities is thought to be due to the large-scale separation between the waves and the particle.
under the homogeneous Neumann boundary condition for u, vi and the homogeneous Dirichlet boundary condition for $\bf{w}$ in a smooth bounded domain $\Omega \subset {\mathbb{R}^n}\left( {n \geqslant 1} \right),$ where ρ > 0, µ > 0, α > 1 and $i=1,\ldots,k$. We reveal that when the index α, the spatial variable n, and the number of equations k satisfy certain relationships, the global solution of the system exists and converges to the constant equilibrium state in the form of exponential convergence.
Trichinellosis is a parasitic zoonosis caused by a nematode parasite of the Trichinella (T.) genus. It poses significant public health issues due to limited effective and safe treatment options, especially for the muscle-encysted larval stage. Citrus paradisi (C. paradisi), with its high content of flavonoids and polyphenols, has been recorded to possess anti-parasitic properties and numerous therapeutic applications. The present work aimed to assess the efficacy of C. paradisi extract peel extract as a therapeutic agent, either alone or combined with albendazole (ABZ), against T. spiralis in experimentally infected mice. Sixty-six lab-bred Swiss albino mice were divided into control and treatment groups, then received either ABZ, C. paradisi extract, or a combination of both during the enteral, migratory, and encapsulation phases of infection. Parasitological, histopathological, and immunohistochemical examinations were performed to evaluate the efficacy of the treatments. All treated groups displayed a highly significant difference (p < 0.001) in larval counts compared to the positive control group, with the combination therapy group having the highest efficacy and the lowest mean count value during different treatment regimens. In addition, treated groups showed improved muscle integrity compared to the positive control group. Moreover, the nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) showed the highest expression reduction in the combination therapy group. These findings highlight the potential of C. paradisi as a complementary therapy to albendazole for treating trichinellosis through muscle larva reduction and mitigation of inflammation.
This study from the Luoxiao Mountains, southeastern China, combines historical information with paleoecological data from two wetlands, yielding a detailed reconstruction of landscape changes over recent centuries. The historical record suggests that people first settled in the region in the late Tang dynasty (618 to 907 CE), and wetland sediments show an increase in charcoal from about this time. During the Qing dynasty in the mid-seventeenth century, a temple complex and a Tea and Salt trade road were constructed near the study sites. Greater impacts are recorded in the wetland closer to the temple site. In the last few hundred years, pollen data show a regional decline of forest cover and the expansion of open vegetation as nearby lowland areas were settled and cleared for agriculture. Proxies for erosion show human impacts in the vicinity of the wetlands. Changes in charcoal inputs reflect regional fire activity, with elevated values around 1500 CE, low values during the Qing dynasty, and a subsequent peak during the twentieth century.
This study explores the impact of market-seeking internationalization, including exporting, industry linkages with foreign multinational enterprises (MNEs) at home (e.g., being a supplier), and market-seeking foreign direct investment (FDI) on the digital transformation of large manufacturing firms from an emerging economy. I revisit the springboard perspective, arguing that serving international customers contributes to emerging market firms gaining dynamic capabilities and eventually leads to the adoption of digital technologies. A four-step mediation analysis, as well as path analysis using structural equation modeling, is employed to test the hypotheses. The results show that dynamic capabilities mediate the relationship between internationalization and digital transformation for exporting and market-seeking FDI, while industry linkages with foreign MNEs at home directly lead to digital transformation. With strategic asset-seeking FDI being controlled, our findings highlight that capability upgrading is not only about acquiring knowledge from outward internationalization but also through the endogenous growth path of learning by doing and knowledge acquisition from inward internationalization.
How can everyday entertainment shape gender politics in authoritarian regimes? Despite autocrats’ heavy control over media, political scientists studying authoritarianism largely neglect television programming. Particularly surprising given their target demographics, cooking shows are absent in political science gender analyses. Drawing from over 600 hours of Turkish cooking show content, I introduce conservative gender edutainment to capture the mechanisms by which TV shows facilitate authoritarian regimes’ gender construction projects. Using quantitative analysis of cooking show content, I first identify two complementary pedagogies — modeling and othering — that respectively teach adherence to, and vilify deviation from, regime-specified behavioral norms. I then use intertextual analysis to extract content that engagingly instructs viewers in the ideal woman in “New Turkey,” the neoconservative vision articulated by Turkey’s ruling (Justice and Development Party) AKP. Findings provide novel insight into vernacular channels of gender construction, while underscoring the added value TV-as-data holds for studies of identity politics in authoritarian contexts.
Justin Garson has argued, contrary to the claims of proponents of purportedly ahistorical theories of functions, that there are no ahistorical theories of functions. In the interest of satisfying uncontroversial desiderata on a theory of functions, the most influential ahistorical views all smuggle in history. I argue that Garson’s case relies on a misinterpretation of the ahistorical accounts he targets and that the details of the misinterpretation are instructive. They highlight often unquestioned assumptions about how a theory of functions fits into a broader account of scientific practice and what theoretical work a definition of function should do.
Over the past 20–30 years, women’s parties have consistently formed across Europe, aiming to improve women’s substantive representation by politicizing gender issues. Despite their potential impact on the policy agenda, empirical knowledge of the full range and scope of issues these parties mobilize is limited. This paper presents a novel mixed-method text analysis of the issue concerns in an original dataset of European women’s parties’ manifestos spanning a 30-year period. I find that parties across contexts share concerns in social justice and social policy. However, two subtypes of women’s party can be differentiated based on issue focus and framing. Essentialist women’s parties predominantly represent women’s material interests, whereas feminist parties additionally tackle structural gender inequality issues, including gender-based violence and human security. These findings provide a foundation for incorporating women’s parties into growing research on party competition over gender issues.
We strengthen two results of Moretó. We prove that the index of the Fitting subgroup is bounded in terms of the degrees of the irreducible monomial Brauer characters of the finite solvable group G and it is also bounded in terms of the average degree of the irreducible Brauer characters of G that lie over a linear character of the Fitting subgroup.
