We synthesized pre-last glacial maximum pollen records to reconstruct North American pollen diversity since ca. 130 ka. Using taxonomic diversity (a measure of the number and abundance of taxa) and functional diversity (a measure of the number and abundance of different phenotypes) we identified temporal and spatial diversity trends for six North American bioregions: Arctic, Intermountain West, Mexico, Pacific Northwest, Southeast, and Yucatán. Reconstructed taxonomic temporal and spatial trends vary among bioregions, with regional diversity patterns captured in the functional metric, suggesting shifts in species composition coincide with shifts in ecosystem function. However, significant shifts in taxonomic pollen diversity differed in frequency, magnitude, and timing from their functional counterparts. Variations in both regional taxonomic and functional diversity response to global and regional temperature trends were evident, suggesting temperature alone does not fully explain changes in species composition. Regional richness estimates exhibited higher stability relative to the weighted diversity estimates indicating low levels of species turnover through Late Quaternary warming–cooling phases. Shifts in regional diversity did not predictably respond to stadial and interstadial transitions. Instead, North American patterns of plant diversity over the last ca. 130 ka differ geographically, likely responding to regional rather than global climate change.

The extant literature on diamond industries in Africa has predominantly focused on men, with few attempts to examine the industry from a gendered lens. I trace women and highlight their gendered roles in the diamond-mining industry in colonial Ghana (Gold Coast). Relying on archival, oral, and visual sources, this article highlights women’s involvement in Ghana’s diamond industry in different capacities—as discoverers, washers, licensed prospectors, and dealers. Ultimately, I argue that the dominance men have enjoyed in studies about diamond mining in Ghana (and Africa generally) reproduces the colonial archive but can be overcome through creative and innovative research.

On July 19, 2024, the International Court of Justice (ICJ) rendered an advisory opinion on Legal Consequences Arising from the Policies and Practices of Israel in the Occupied Palestinian Territory, Including East Jerusalem. By votes of 11–4, the Court found that Israel's continued presence in the Occupied Palestinian Territory (OPT) was unlawful and needed to be ended as rapidly as possible. By a 14–1 majority, the Court also found that Israel was obligated to cease all new settlement activities, evacuate existing settlers from the OPT, and make reparation. The ICJ further opined by votes of 12–3 that all states and international organizations were obliged not to recognize as legal the situation arising from Israel's unlawful presence in the OPT, that all states must refrain from giving aid or assistance to the maintenance of that situation, and that the United Nations “should consider the precise modalities” required to bring Israel's unlawful presence in the OPT to an end.

Academic blogging is a digital platform for “doing” knowledge translation in the humanities. Knowledge translation is the process of communicating research outcomes outside academia so the public can benefit. While science communication is widely recognized as a medium for communicating science, technology, engineering, and mathematics knowledge with the public, formal mechanisms for knowledge facilitation in the humanities are not as well established. Academic blogging is core to the social value and impact of the humanities, representing an important open access entry point into humanistic scholarly debates. Drawing on a developing literature about academic blogging as well as a survey we conducted with readers, authors, and editors of academic blogs, this article shows how doing knowledge translation with academic blogs can support the three core domains of a university’s mission: research, teaching, and public outreach. With your research, you can use academic blogs to facilitate networking and collaborations; with your teaching, you can use academic blogs as tools to introduce students to a new topic; with public outreach, doing academic blogging enables you to connect with diverse readerships. Academic blogs contribute to knowledge translation for and about the humanities, from foundational concepts to new research and the more hidden aspects of academic practice.

Which additional epistemic skills or attributes must a competent journalist possess in order to produce competent science journalism? I aim to answer this question by bringing together insights from journalism, science communication, and epistemology. In Section 2, I outline the Epistemic Challenge for Science Journalism. In Section 3, I present the dominant answer in the literature, the Knowledge-Based Solution, and argue against it. In Section 4, I propose an alternative, the Confirmation-Based Solution. In Section 5, I argue that this solution can address recent concerns regarding journalistic objectivity. Section 6 discusses my proposal in the context of epistemological debates about norms of assertion. Section 7 concludes.

We describe a geometric, stable pair compactification of the moduli space of Enriques surfaces with a numerical polarization of degree $2$, and identify it with a semitoroidal compactification of the period space.

Liouville-type theorems for the steady incompressible Navier–Stokes system are investigated for solutions in a three-dimensional (3-D) slab with either no-slip boundary conditions or periodic boundary conditions. When the no-slip boundary conditions are prescribed, we prove that any bounded solution is trivial if it is axisymmetric or $ru^r$ is bounded, and that general 3-D solutions must be Poiseuille flows when the velocity is not big in $L^\infty$ space. When the periodic boundary conditions are imposed on the slab boundaries, we prove that the bounded solutions must be constant vectors if either the swirl or radial velocity is independent of the angular variable, or $ru^r$ decays to zero as $r$ tends to infinity. The proofs are based on the fundamental structure of the equations and energy estimates. The key technique is to establish a Saint-Venant type estimate that characterizes the growth of the Dirichlet integral of non-trivial solutions.

It is widely presumed that privacy is ‘factive’, i.e. that it cannot be diminished by accessing or disseminating falsehoods. But if this is so, what wrongs are committed in cases where others access documents of ours (letters, medical records, etc.) which contain false information? In this article, I examine various ways of explaining the wrongfulness of accessing and dissemination falsehoods (defamation; that privacy can be violated without being diminished; ‘control’ accounts of privacy; downstream revelations of truths; that falsehoods diminish ‘propositional’ or ‘attentional’ privacy). I lay out what each of these accounts misses about accessing falsehoods, about privacy, and/or about the right to privacy. I then propose two alternative ways of accounting for the intuitive wrongfulness of accessing and disseminating falsehoods: viewing them as merely ‘attempted’ privacy violations and weakening the truth condition of privacy diminishments.

Children’s speech becomes longer and more complex as they develop, but the reasons for this have been insufficiently studied. This study examines how changing linguistic choices in children are linked to interactive factors by analysing Who-question sequences in Japanese child–caregiver conversations. The interactive factors in focus are progressivity and balanced joint activity, which are core aspects of conversational interaction. Our analysis reveals that as children respond to Who-questions, their responses grow in length and multifunctionality. This growth is positively associated with progressivity, namely a quicker completion of the question sequence, and reduced functional load in the interlocutor’s contributions, resulting in more balanced joint activity. These findings suggest that children adapt their linguistic choices by observing and aligning them with their interactive goals in conversational sequences.
