En este trabajo presentamos los resultados del análisis traceológico de una muestra cerámica procedente de sitios arqueológicos del sector meridional del valle de Abaucán (Tinogasta, Catamarca, Argentina), con el objetivo de visualizar cadenas operativas de los procesos de modelado durante el primer milenio de la era. Para ello la muestra seleccionada, de contextos arqueológicos y relevamientos de piezas de museos, fue sometida al análisis de traza a través de la propuesta de García Roselló y Calvo Trías (2013). Adicionalmente, nos valimos de la experimentación como método de estudio para observar el proceso de manufactura de forma directa y obtener un parámetro controlado que permita la comparación con el material arqueológico. Los resultados brindaron datos con un alto grado de detalle del levantado de las piezas, relacionando las trazas con elecciones técnicas específicas, con herramientas y gestos manuales aplicados por los alfareros en el pasado del oeste de Catamarca.

This thesis presents my contributions to various aspects of the theory of universally Baire sets. One of these aspects is the smallest inner model containing all reals whose all sets of reals are universally Baire (viz., $L(\mathbb {R})$) and its relation to its inner model $\mathsf {HOD}$. We verify here that $\mathsf {HOD}^{L(\mathbb {R})}$ enjoys a form of local definability inside $L(\mathbb {R})$, further justifying its characterization as a “core model” in $L(\mathbb {R})$. We then study a “bottom-up” construction of more complicated universally Baire sets (more generally, determined sets). This construction allows us to give an “L-like” description of the minimum model of $\mathsf {AD}_{\mathbb {R}} + \mathsf {Cof}(\Theta ) = \Theta $. A consequence of this description is that this minimum model is contained in the Chang-plus model. Our construction, together with Woodin’s work on the Chang-plus model, shows that a proper class of Woodin cardinals which are limits of Woodin cardinals implies the existence of a hod mouse with a measurable limit of Woodin cardinals whose strategy is universally Baire.

Another aspect of the theory of universally Baire sets is the generic absoluteness and maximality associated with them. We include some results concerning generic $\Sigma _1^{H(\omega _2)}$-absoluteness with universally Baire sets as predicates or parameters, as well as generic $\Pi _2^{H(\omega _2)}$-maximality with universally Baire sets as predicates. In the second case, we are led to consider the general question of when a model of an infinitary propositional formula can be added by a stationary-set-preserving poset. We characterize when this happens in terms of a game which is a variant of the Model Existence Game. We then give a sufficient condition for this in terms of generic embeddings.

We report new AMS radiocarbon dates of 16 samples from the Holocene deposits of the Vistula Spit, a large coastal barrier landform on the Southern Baltic coast. Collection of the samples was conducted directly from the sedimentary succession excavated during 2020–2022 construction of the Vistula Spit shipping canal. The dated material represents several paleosol horizons and peat lenses buried in the dune deposits, as well as their substrate – beach and shallow marine deposits.

Adam Smith seeks to explain in the Wealth of Nations and Lectures on Jurisprudence the persistence of slavery as an institution. In order to accomplish this, he also draws on arguments he had developed in The Theory of Moral Sentiments. The result is a sophisticated explanation that bridges economic, psychological, and moral considerations. After presenting Smith’s explanation, I will consider a discussion of the moral wrong of slavery in the work of Ottobah Cugoano, author of the incisive criticism of the slave trade Thoughts and Sentiments on the Evil of Slavery. I will suggest that Cugoano’s account of what is morally wrong in slavery shows an important lacuna in Smith’s views.

This special issue, “On Their Own Terms: Experts in Imperial China,” examines various kinds of expertise from Han times into the twentieth century from the angle of practitioners themselves, and sometimes even on their own terms.

Paul Erdős and R. Daniel Mauldin asked a series of questions on certain types of polygons of area $1$, the vertices of which can be found in every planar set of infinite Lebesgue measure. We address two of these questions, one on cyclic quadrilaterals and the other on convex polygons with congruent sides, with, respectively, positive and negative answers.

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.

Politicization is one of the most fundamental characteristics of Chinese society, manifested in the direct and comprehensive control of society by the Chinese Communist Party (CCP). Methods include soft control through ideology and coercive control through campaigns. Based on the varying degrees of the CCP’s social control, the trajectory of China’s regime politicization can be divided into four periods: (1) the politicized regime of 1949–1965, (2) the hyper-politicized regime of 1966–1978, (3) the de-politicized regime of 1979–2012, and (4) the re-politicized regime of 2013–2023. We established an annual politicization index for the years 1949 to 2023 through a content analysis of two million articles in the People’s Daily, validating the trajectory of politicization changes in China. We use a model analysis of CCP membership attainment to demonstrate the applicability of the index in assessing how regime dynamics affect Party membership across the four periods.
