When two black male directors produce university productions of Jackie Sibblies Drury’s Fairview in different parts of the country at the same time, they bond over their shared understanding of the white gaze, and how black people are created and viewed in the white imagination, both in the play and in their own lives.

A range of sizes of eight sea urchin species in the Family Echinometridae (Echinostrephus aciculatus, Heliocidaris erythrogramma, Colobocentrotus atratus, Heterocentrotus mamillatus, Heterocentrotus trigonarius, Echinometra mathaei, Echinometra lucunter, and Echinometra vanbrunti) were digitized and their shapes decomposed using elliptical Fourier analysis to quantify shape differences. Coefficients of sines and cosines of harmonics were used in a principal components analysis to show the separation of species. The principal component analysis shows the Echinometridae shape morphospace with the greatest separation of Echinostrephus and Colobocentrotus from other species. Major loadings were related to morphological measurements: height/diameter, lift of the oral surface above the substrate, and position of the ambitus to height. All species showed an increase in height/diameter with size, but only some species showed a correlation of oral lift or position of the ambitus with Fourier coefficients.

Given $p\in[1,\infty)$ and a bounded open set $\Omega\subset\mathbb{R}^d$ with Lipschitz boundary, we study the $\Gamma$-convergence of the weighted fractional seminorm

\begin{equation*}[u]_{s,p,f}^p=\int_{\mathbb{R}^d} \int_{\mathbb{R}^d} \frac{|\tilde u(x)- \tilde u(y)|^p}{\|x-y\|^{d+sp}}\,f(x)\,f(y)\,\mathrm{d} x\,\mathrm{d} y,\end{equation*}

as $s\to1^-$ for $u\in L^p(\Omega)$, where $\tilde u=u$ on $\Omega$ and $\tilde u=0$ on $\mathbb{R}^d\setminus\Omega$. Assuming that $(f_s)_{s\in(0,1)}\subset L^\infty(\mathbb{R}^d;[0,\infty))$ and $f\in\mathrm{Lip}_b(\mathbb{R}^d;(0,\infty))$ are such that $f_s\to f$ in $L^\infty(\mathbb{R}^d)$ as $s\to1^-$, we show that $(1-s)[u]_{s,p,f_s}^p$ $\Gamma$-converges to the Dirichlet $p$-energy weighted by $f^2$. In the case $p=2$, we also prove the convergence of the corresponding gradient flows.

Recent corporate scandals and excessively egotistical behavior on the part of organizational leaders underscore the need for industrial and organizational (I-O) psychology and human resource (HR) scholars and practitioners to critically examine how organizational systems and practices can stimulate leader narcissism. Whereas most organizational scholarship considers leader narcissism to be a stable input that influences important organizational outcomes, we challenge organizational scholars and practitioners to further inspect how organizational practices may either stimulate or suppress leader narcissism. We focus on HR practices as one specific set of organizational practices within the area of expertise of I-O psychologists and HR professionals. Drawing on self-categorization theory, we argue that highly personalizing HR practices (e.g., hypercompetitive leader selection, high-potential programs, elevated leader pay) can encourage leaders to define themselves in terms of a “special” personal identity in ways that set them apart from the broader collective within organizations and in turn facilitate leader narcissism. In contrast, we argue that depersonalizing HR practices (e.g., rotational leader selection, inclusive developmental programs, interdependent rewards) can encourage leaders to act in group-oriented ways that benefit the interests of others in an organization—and beyond. We call on organizational scholars and practitioners to consider more carefully how HR practices—often designed with the goal of cultivating leadership potential—may unintentionally reinforce leader narcissism. With this analysis, we hope to stimulate research in this area and offer insights to shape HR policies and practices in ways that discourage destructive forms of leader narcissism.

Understanding the regional diversity of epiphytic bryophytes along elevation gradients is crucial for assessing forest ecosystems, particularly in areas vulnerable to climate change. The study aimed to compare the composition and richness of epiphytic bryophytes colonising on basal trunks of Cryptomeria japonica, a predominant conifer in the Darjeeling hills, across different altitude zones, and to assess the underlying macroclimatic factors driving such variations. The field surveys were performed at nine elevation zones of Darjeeling between 1450 and 2250 m above sea level. Bryophytes belonging to 37 genera, primarily from Dicranales and Hypnales, were recorded. Diversity profiles reflected low evenness, with Syrrhopodon confertus emerging as the dominant moss in the community. Species richness displayed a multimodal pattern along the altitudinal gradient. The trend exhibited an initial hump peaking at 1550 m and a subsequent rise of richness above 2150 m. About 43.24% of species were confined to a single altitude zone, signifying a narrow range of occurrence. The epiphyte compositions of 1450, 1550 and 2250 m were distinct compared to the other elevation zones. Furthermore, statistical evaluation predicted the influence of climatic parameters such as precipitation, temperature stability and solar radiation on bryophyte assemblage. Therefore, the outcome provides a broad overview of the distribution of bryophytes at managed conifer forests and underscores the significance of elevation-specific climatic conditions in shaping bryophyte diversity, which can be useful for designing their effective conservation strategies.

Adam Smith is often read as having sought to develop a systematic and universally applicable science of political economy, but in fact he did not believe that it was even possible to do so. This is true for a variety of reasons. First, Smith was generally skeptical of system-building, holding that intellectual systems tend to be reductive and distorting. Although Smith aspired to develop a theory of natural jurisprudence that would lay out a set of universally applicable laws, such laws were in fact incompatible with his own conception of justice. Smith’s general approach to politics and political economy also tended to be far more pragmatic, in several senses of that term, than universal or scientific. Finally, Smith’s aversion to the “spirit of system” in politics led him to be wary of implementing even his own preferred policies immediately or in their entirety.

This paper presents the design and implementation of Jaeger UTFPR, an open-source, low-cost, remote-controlled tiny humanoid robot measuring just 12 cm in height. Developed with a focus on accessibility and affordability, the robot integrates 3D-printed components, cost-effective electronics, embedded systems, and wireless communication to provide real-time audio and video feedback through a virtual reality (VR) interface. Operators control Jaeger UTFPR using a VR headset and motion controllers, enabling immersive telepresence and direct manipulation of the robot’s movements. With a total cost of just a few tens of dollars, this innovative solution offers broad applications in education, entertainment, research, and remote inspection, serving as an accessible platform for robotics enthusiasts and developers. Experimental evaluations demonstrate the system’s effectiveness in balancing performance and cost, validating its potential as a tool for immersive robotics experiences.

Another scholarly journal has apparently decided that no book should be reviewed by somebody named in the book’s acknowledgements. Margaret Bent has over seventy names in her main list, and she warmly thanks or praises dozens of others in the course of her book, which is a definitive report on the state of play in research on the motet repertory of the years 1300–1420. It is safe to say that nobody who is at all qualified to review the book is omitted. That is partly because Bent has been inviting authorities from across the world to speak at her monthly All Souls seminars for over thirty years, and since the time of the Covid lockdown the seminars have been seen internationally on Zoom, with respondents also from across the world. An astonishing and massive public has contributed to making her book what it is. (Declaration: I am indeed named, but I learnt so much from the book that I feel required to make my statement.)

Adam Smith’s Wealth of Nations is standardly assumed, by apologists and critics alike, to have offered a theory of what money is: a “means of exchange” whose raison d’etre is to ease the inconveniences of barter. The present discussion rejects this consensus. Read charitably, neither Smith’s origin story in Book I nor his account of “the great wheel of circulation” in Book II traffics in a theory of what money is. Rather, the Wealth of Nations offers no theory of the nature of money at all. What Smith presents, instead, is a functionalist story of a piece with David Hume’s empiricism, which does not make any claims about natures or essences. Smith’s reply to the mercantilist theory of money—that money is specie—is not a rival theory of money’s true nature, but rather a broad depiction of the various ways money brings “conveniency.”

Este trabajo vincula la evolución del poder de mercado de la banca española con la liberalización financiera entre 1970 y 1990. Se realiza una cronología de las medidas de desregulación y se mide empíricamente el poder de mercado, para lo que se ha elaborado un indicador directo, el índice Lerner. Se comprueba que la desregulación bancaria no fue lineal, y las entidades bancarias compitieron incluso antes de la liberación completa. Se aprecia que el poder de mercado disminuyó en los años 70, por la mayor competencia a través de la red de oficinas, seguido por un aumento en los 80, coincidiendo con un parón en las medidas liberalizadoras. Desde 1988, la competencia se intensificó de nuevo con la consolidación de las medidas liberalizadoras. Además, los resultados permiten descartar la tesis de las reformas financieras consideradas como un pacto entre la banca y las autoridades que no alteró el marco competitivo permitiendo a los grandes bancos cartelizar el sector.

Nacera Belaza asks a dancer to “be sound.” This is not a metaphor, nor is it a request for the dancer to produce sound, talk, or sing. It is a task given with little explanation but meant to unlock a way of performing without pretending, stirring up questions about the historically racialized possibility of realness, transparency, and transmission, and drawing attention to profound sensory experiences that might never be clear. Here, performing one impossible task (being sound) becomes instructive in doing another (writing dance).
