College students (those enrolled in two- and four-year postsecondary institutions) with caregiving responsibilities for children or other dependents face unique challenges balancing academic and caregiving duties. This scoping review aimed to describe the prevalence of food insecurity among United States college student caregivers and their experiences with food insecurity, dietary quality/intake, academic outcomes, and food security programming. A search of peer-reviewed and grey literature was conducted in four databases: CINAHL, GOOGLE SCHOLAR, EMBASE, and MEDLINE. Identified articles were evaluated against inclusion criteria. Of 162 articles identified, 61 articles met eligibility criteria and underwent data extraction and descriptive analysis. Forty-two articles (69%) reported the prevalence of food insecurity among college student caregivers, with prevalence ranging from 9-79%. Single parents, students of color, LGBTQ+ individuals, and those with multiple dependents had increased food insecurity risk. Thirteen studies examined dietary patterns, finding caregiving students prioritized feeding their children, reduced their own meal sizes, and chose low-cost, low-nutrient foods due to budget constraints. Academic challenges included difficulties in time management and scheduling stress. No studies examined GPA or academic performance. Thirteen studies identified the use of food assistance programs. Food assistance programs were underutilized due to limitations like restricted pantry hours and availability. Housing insecurity frequently co-occurred with food insecurity. Food insecurity disproportionately affects college student caregivers compared to non-caregiving students. Comprehensive programming is needed to support food and nutrition security, including connections to government and university food assistance programs, childcare services, and program modifications to reduce barriers to academic success for caregiving students.

Archaeological sampling is a critical yet inconsistently applied aspect of field methodology. Poorly designed strategies produce biased or irreproducible results, especially when recovery is labor-intensive and research expectations are high. This article addresses that challenge through the lens of spatial microrefuse analysis, using simulation modeling to evaluate current practices and improve sampling design, training, and planning. A review of 27 published microrefuse studies reveals wide variation in sampling strategies, unit sizes, and volumes, with little evidence of statistical justification. To explore the consequences of this variation, I introduce the Archaeological Sampling Experiment Laboratory (tASEL), an open-source simulation tool developed in NetLogo and archived in the CoMSES model library. tASEL allows archaeologists to construct artifact distributions and test random, systematic, or hybrid sampling frames with immediate visual and statistical feedback. I used tASEL to conduct 22,000 virtual sampling experiments across two artifact distributions: a diffuse random scatter and a highly clustered pattern. Results show that sampling performance varies significantly by distribution, sample size, and frame design. Random strategies produced the highest accuracy and lowest bias. I conclude by demonstrating how tASEL can be used in classroom and field contexts to improve sampling literacy and support more robust archaeological practice.

This study investigates the impact of socio-economic status (SES) on children’s vocabulary, focusing on the distinction between vocabulary breadth (number of words known) and vocabulary depth (quality of word knowledge). It aims to determine whether SES affects both dimensions equally and whether the relationship between SES and vocabulary depth is mediated by vocabulary breadth. Participants were 219 children schooled in France in fourth and fifth grades who had French as their dominant language. Analyses showed that SES significantly influences vocabulary breadth, as predicted by previous research. Importantly, it also impacts vocabulary depth. Mediation analysis revealed that vocabulary breadth can mediate this effect depending on the task used to measure vocabulary depth.

This article argues that it is not possible to understand a nation’s ideals, values, goals, and institutional practices or its past, present, and future possibilities without an examination of its foundational philosophy and the historical evolution of that philosophy. Canada is no exception in this regard. Canada’s underlying philosophy is objectively idealistic, inclusive, duty and community oriented, examines life as it is lived, and moves forward in an evolutionary and dialectical fashion. If this hypothesis is true, then why is it the case that the study of this philosophy is largely absent from Canadian university curricula and public discourse?

We study the asymptotic properties, in the weak sense, of regenerative processes and Markov renewal processes. For the latter, we derive both renewal-type results, also concerning the related counting process, and ergodic-type results, including the so-called $\varphi$-mixing property. This theoretical framework permits us to study the weak limit of the integral of a semi-Markov process, which can be interpreted as the position of a particle moving with finite velocities, taken for a random time according to the Markov renewal process underlying the semi-Markov one. Under mild conditions, we obtain the weak convergence to scaled Brownian motion. As a particular case, this result establishes the weak convergence of the classical generalized telegraph process.

What do we mean by backlash against rights? How does backlash vary? What explains its variation? Although backlash is recognized as a crucial problem in the legal mobilization literature, it is treated as a residual category. This paper proposes a conceptual apparatus and research agenda for its identification and analysis. We propose a definition of backlash that distinguishes it from ordinary legal mobilization, and identify key dimensions along which backlash varies – actors, realms, tactics, goals, and outcomes. We propose typologies to explore how backlash differs across these dimensions. For each dimension, we offer criteria to distinguish between the different forms of backlash, use examples to illustrate their particularities, and propose hypotheses regarding the factors that may explain variation. The main innovation of our approach is the concept of veiled backlash, which occurs in the backdoor of state agencies when regressive networks have dominant influence thereon. We claim that veiled backlash often employs pseudolegal tactics, which are difficult to detect and challenge, thus increasing the likelihood of backlash’s success. We further argue that veiled backlash tends to be cumulative; it has the ambitious goal of curtailing pro-rights policies or state agencies, yet it can go unnoticed because it relies on tactics that appear like ordinary legal mobilization.

This paper adopts a sociosemiotic perspective to examine how normative consensus and legitimacy are constructed in global artificial intelligence (AI) governance discourse. Drawing on a corpus of forty-seven international normative documents, the study identifies an emerging cross-textual consensus around three core principles – Safety, Human-centric and Fairness – and analyses how these are semiotically encoded. The findings reveal tensions between state and non-state actors, and between semiotic agreement and practical implementation. For instance, ‘Safety’ is often framed through securitisation discourse, while ‘Human-centric’ is increasingly grounded in international human rights frameworks. The study further shows that discursive strategies such as nominalisation help establish surface-level consensus but introduce ambiguity that undermines enforceability. By conceptualising governance texts as dynamic semiotic systems, this research moves beyond the hard law–soft law dichotomy, revealing global AI regulation as a contested arena of meaning-making. It offers a theoretical basis for advancing more inclusive and operational governance models.

The shared-syntax argument of bilingual language representations has support from studies of cross-linguistic structural priming. However, more research needs to be conducted to support the grammatical co-activation hypothesis. The current study investigates the behavioral patterns of bilingual grammatical co-activation in comprehension, taking into account the age of immersion (AoI), which significantly affects the performance of bilinguals. Specifically, we tested 114 native speakers of English: 84 English–French bilinguals (53 early and 31 late learners of French) and 30 functional English monolinguals with a grammatical maze task using English stimuli manipulated with the two opposing English and French rules of adverb placement. Early bilinguals with an AoI earlier than 7 appear to be more accepting of the French adverb placement while reading English sentences. This suggests that earlier bilinguals are more likely to show co-activation (and competition) of the two languages. Results support the shared-syntax system of bilingual grammatical representations.

Our research set out to determine how the distinctive social ethos and tactile appeal of physical modular synthesisers could be transferred into extended reality contexts. Employing a ‘netnographic’ approach, the research examined content drawn from social media platforms including YouTube, Discord and Reddit. Particular attention was given to an analysis of ‘PatchWorld’ as the most prominent commercially available virtual modular synthesis tool. Additionally, ‘OpenSoundLab’, an open-source mixed-reality modular sound laboratory that was developed in earlier research, was adapted to allow multi-user sessions in mixed reality (MR), both locally co-located or remotely. Commercial standalone headsets were handed out to three artists in order to observe how they translate their patch and performance practices into extended realities. Distributing both the headsets and software functioned as a form of ‘cultural probe’, enabling the collection of detailed user experiences and acting as a prompt for informed conversations. Through this process, the evaluation yielded evidence that some of the most valued aspects of using physical modular systems can be translated to virtual modular systems, especially since these share a similar – if not greater – potential for creative and social immersion in a spatial instrument.

We analyzed the determinants and potential of U.S. agricultural exports to South Asian, Southeast Asian, and Southern African countries by employing a stochastic frontier gravity model. Our estimated results suggest that importers’ GDP, institutional quality, globalization level, and participation in Trade and Investment Framework Agreement significantly promote U.S. exports, while geographic distance and landlocked status act as major constraints. The derived technical efficiency scores reveal considerable underperformance of U.S. exports. We recommend that the United States can expand and strengthen its Trade and Investment Framework Agreement, institutional cooperation, interconnectedness, and direct policy focus toward countries with the largest export gaps.

Planar particle image velocimetry (PIV) measurements were conducted to investigate turbulent flows through a square duct roughened by transverse rectangular ribs of four blockage ratios (${\textit{Br}}=0.1$, 0.15, 0.2 and 0.25) at a bulk Reynolds number of ${\textit{Re}}_b = 9400$. In contrast to the classical two-dimensional (2-D) rib-roughened boundary-layer flows, the turbulent flow studied here is intrinsically three-dimensional (3-D) and inhomogeneous, complicated by not only the internal shear layers (ISLs) triggered by the rib crests, but also the intense interaction of the four boundary layers developing over duct sidewalls. It is observed that turbulent motions near the rib crest are mainly dominated by the ejection and sweep events. As the blockage ratio increases, the magnitudes of Reynolds stresses near the rib crest increase significantly attributed to enhanced sweep events and large-scale flapping motions. The results of temporal auto-correlations and spatial two-point auto-correlations show that both temporal and spatial integral scales of turbulence structures are dominated by the streamwise velocity fluctuations, which increase as the rib height increases. Based on proper orthogonal decomposition (POD) analyses, it is interesting to observe that the ISL near the rib crest is dominated by both the low- and high-frequency flapping motions characteristic of the first POD mode.

A potentially powerful argument for police abolition appeals to root causes of crime. The root causes of crime are (e.g.) poverty and inequality caused by capitalism. By targeting crime at the roots, we can render the police obsolete and abolish them. I argue here that the root cause argument fails. Despite the suggestive metaphor, the fundamental causes of crime are deep and valuable, or in other words not uproot-able. They are essential to us, or we have good reason not to uproot them. To show this, I develop some simple models or recipes for crime inspired by Thomas Hobbes’s model of conflict in the state of nature and by contemporary theories of crime. The models suggest that at best we can manage these causes, and in turn the resulting crime. There is, however, no hope of fundamental reforms that do away with the need for social monitoring and sanctioning, or policing.

The Fremouw Formation of the Central Transantarctic Mountains preserves the southernmost record of Early to Middle Triassic terrestrial ecosystems that developed in the aftermath of the end-Permian mass extinction. Although the well-studied vertebrate fossil assemblage in the lower member of the Fremouw Formation provides a detailed snapshot of subpolar ecosystems immediately following the end-Permian mass extinction, the nature of how long these earliest Triassic communities persisted at the southern extremes of Pangaea is virtually unknown. Importantly, the timing and extent of the major faunal turnover between the lower and upper members of the Fremouw Formation have been obscured by the paucity of fossil specimens historically recovered from the middle member. Here, we describe the first vertebrate assemblage from the middle member of the Fremouw Formation, including occurrences of procolophonids (including Procolophon trigoniceps) and archosauromorphs (including Prolacerta broomi), as well as infilled vertebrate burrow casts referrable to the ichnogenus Reniformichnus. We also summarize and expand on lithostratigraphic shifts between the lower, middle and upper members of the Fremouw Formation. Although the sample size of vertebrate body fossils is small compared to the lower and upper members of the Fremouw Formation, we discuss the evidence for a taphonomic shift between the lower and middle members of the Fremouw Formation that favours preservation of smaller-bodied taxa and individuals in the latter. Together, these preliminary data add crucial context to the persistence of subpolar vertebrate communities in the earliest Mesozoic.

This article examines the creation in the early 1710s of a library at the Dublin military hospital for old soldiers known as the Royal Hospital Kilmainham (RHK). It shows that the library was created after an appeal by the master of the RHK, describes the books in the collection, and examines the gifts from a significant pool of seventy-one high-status men and women across Ireland from which the collection was constructed. It considers why the library was created at this time and its use during the two centuries that would elapse before the final closure of the hospital in the wake of Irish independence. This article is the first ever examination of the physical books and makes significant use of the minute books of the board of the RHK and its sub-committees, manuscript records that historians have tended to assume were lost or destroyed after the evacuation of British troops from the twenty-six counties.
