The present study tested Spanish heritage speakers' (HSs') production and selection of subjunctive mood in volitional clauses. Four groups participated to expose the effects of age on subjunctive acquisition: Spanish-dominant bilingual adults (SDBA; n = 18), HSs in fifth grade (HS5; n = 41), HSs in seventh/eighth grades (HS7/8; n = 34) and HS adults (HSA; n = 34). SDBAs produced and selected the subjunctive more than HS groups. There were no differences in production and selection between the HS7/8 and HSA groups, both of whom produced and selected subjunctive mood more frequently than the HS5 group. These results point toward protracted heritage language development. HSs selected the subjunctive more than they produced it, supporting theories that dissociate between mapping forms onto morphology and underlying syntactic competence. Finally, proficiency and frequency of use modulated individual variability between HSs. Results are addressed relative to incomplete acquisition, protracted development and feature reassembly.

One of the elegant achievements in the history of proof theory is the characterization of the provably total recursive functions of an arithmetical theory by its proof-theoretic ordinal as a way to measure the time complexity of the functions. Unfortunately, the machinery is not sufficiently fine-grained to be applicable on the weak theories, on the one hand and to capture the bounded functions with bounded definitions of strong theories, on the other. In this paper, we develop such a machinery to address the bounded theorems of both strong and weak theories of arithmetic. In the first part, we provide a refined version of ordinal analysis to capture the feasibly definable and bounded functions that are provably total in $\textrm{PA}+\bigcup _{\beta \prec \alpha } \textrm{TI}({\prec_{\beta}})$, the extension of Peano arithmetic by transfinite induction up to the ordinals below $\alpha$. Roughly speaking, we identify the functions as the ones that are computable by a sequence of $\textrm{PV}$-provable polynomial time modifications on an initial polynomial time value, where the computational steps are indexed by the ordinals below $\alpha$, decreasing by the modifications. In the second part, and choosing $l \leq k$, we use similar technique to capture the functions with bounded definitions in the theory $T^k_2$ (resp. $S^k_2$) as the functions computable by exponentially (resp. polynomially) long sequence of $\textrm{PV}_{k-l +1}$-provable reductions between $l$-turn games starting with an explicit $\textrm{PV}_{k-l +1}$-provable winning strategy for the first game.

This article presents a business history of the Barranquilla Railway and Pier Company (BRPC) and its impact on Colombia’s Caribbean region. It explores the company’s operations, profitability, shareholders, infrastructure development, and competition with other coastal railways for insights into the role of foreign capital in regional growth. The BRPC’s railway and port infrastructure connected the coastal city of Barranquilla with the Colombian interior, allowing the city to supplant Cartagena as the country’s principal international port. Statistical analysis reveals the railway’s remarkable profitability, which attracted transnational investors, who consolidated majority control. The company’s ability to leverage engineering expertise and capital underscored its strategic significance, yet its interests centered on protecting its transport monopoly. The railway’s lack of visibility in London and information asymmetries shaped investor perceptions. Extending the pier demonstrated BRPC’s role in accommodating rising export volumes during Colombia’s “despegue cafetero.” However, the railway faced obsolescence, as the government opened the obstructing Bocas de Ceniza sandbank and pursued railway nationalization. The railway’s redundancy, demographic shifts, and rise of Buenaventura underscore its eventual decline. This paper reveals the complex dynamics between foreign capital, infrastructure, and trade monopolies in shaping uneven development. It highlights the BRPC’s overlooked yet fundamental role in Colombia’s export economy and Barranquilla’s ascendancy.

This paper studies a bi-dimensional compound risk model with quasi-asymptotically independent and consistently varying-tailed random numbers of claims and establishes an asymptotic formula for the finite-time sum-ruin probability. Additionally, some results related to tail probabilities of random sums are presented, which are of significant interest in their own right. Some numerical studies are carried out to check the accuracy of the asymptotic formula.

The cry of “Get married women out of the factories!” echoed across the Spanish industrial landscape at the turn of the twentieth century, driven by two intertwined factors. From a societal perspective, women's place was at home, not in factories. On an economic note, concerns arose over women's lower wages displacing men from jobs. This research delves into a case study of a workers’ claim aimed against women. It aims to illuminate the interplay of social demands and gender dynamics in labour history and business operations. Using as a case study a strike among male workers at the Amatller chocolate factory in May 1890, it seeks insights into gender complexities and women's challenges when joining the workforce. Male factory workers sought better conditions but directed their frustrations at women, influenced by prevailing social discourse. Women joined the factory, but portraying them as victors would be an oversimplification. Their presence was restricted, confined to manual tasks, with few opportunities for advancement.

In the current pre-registered study, we examined the associations between shared book reading, daily screen time, and vocabulary size in 1,442 12- and 24-month-old Norwegian infants. Our results demonstrate a positive association between shared reading and vocabulary in both age groups, and a negative association between screen time and vocabulary in 24-month-olds. Exploratory analyses revealed that the positive relationship between shared reading and expressive vocabulary in 12-month-olds was stronger in lower SES groups, suggesting that shared reading may act as a compensatory mechanism attenuating potentially impoverished learning environment and parent-infant interactions in low-SES families.

We propose a systematic design approach for the precast concrete industry to promote sustainable construction practices. By employing a holistic optimization procedure, we combine the concrete mixture design and structural simulations in a joint, forward workflow that we ultimately seek to invert. In this manner, new mixtures beyond standard ranges can be considered. Any design effort should account for the presence of uncertainties which can be aleatoric or epistemic as when data are used to calibrate physical models or identify models that fill missing links in the workflow. Inverting the causal relations established poses several challenges especially when these involve physics-based models which more often than not, do not provide derivatives/sensitivities or when design constraints are present. To this end, we advocate Variational Optimization, with proposed extensions and appropriately chosen heuristics to overcome the aforementioned challenges. The proposed approach to treat the design process as a workflow, learn the missing links from data/models, and finally perform global optimization using the workflow is transferable to several other materials, structural, and mechanical problems. In the present work, the efficacy of the method is exemplarily illustrated using the design of a precast concrete beam with the objective to minimize the global warming potential while satisfying a number of constraints associated with its load-bearing capacity after 28 days according to the Eurocode, the demolding time as computed by a complex nonlinear finite element model, and the maximum temperature during the hydration.

Retrieval-augmented generation (RAG) adds a simple but powerful feature to chatbots, the ability to upload files just-in-time. Chatbots are trained on large quantities of public data. The ability to upload files just-in-time makes it possible to reduce hallucinations by filling in gaps in the knowledge base that go beyond the public training data such as private data and recent events. For example, in a customer service scenario, with RAG, we can upload your private bill and then the bot can discuss questions about your bill as opposed to generic FAQ questions about bills in general. This tutorial will show how to upload files and generate responses to prompts; see https://github.com/kwchurch/RAG for multiple solutions based on tools from OpenAI, LangChain, HuggingFace transformers and VecML.

The scarce literature on the processing of internally headed relative clauses (IHRCs) seems to challenge the universality of the subject advantage (e.g., Lau & Tanaka [2021, Glossa: A Journal of General Linguistics, 6(1), 34], for spoken languages; Hauser et al. [2021, Glossa: A Journal of General Linguistics, 6(1), 72], for sign languages). In this study, we investigate the comprehension of subject and object IHRCs in Italian Sign Language (LIS) deaf native and non-native signers, and hearing LIS/Italian CODAs (children of deaf adults). We use the eye-tracking Visual-only World Paradigm (Hauser & Pozniak [2019, Poster presented at the AMLAP 2019 conference]) recording online and offline responses. Results show that a subject advantage is detected in the online and offline responses of CODAs and in the offline responses of deaf native signers. Results also reveal a higher rate of accuracy in CODAs' responses. We discuss the difference in performance between the two populations in the light of bilingualism-related cognitive advantages, and lack of proper educational training in Italian and LIS for the deaf population in Italy.

We show that an infinite group G definable in a $1$-h-minimal field admits a strictly K-differentiable structure with respect to which G is a (weak) Lie group, and we show that definable local subgroups sharing the same Lie algebra have the same germ at the identity. We conclude that infinite fields definable in K are definably isomorphic to finite extensions of K and that $1$-dimensional groups definable in K are finite-by-abelian-by-finite. Along the way, we develop the basic theory of definable weak K-manifolds and definable morphisms between them.

Politics in environmental education is conspicuous by its absence. This article is a plea to make politics–the study of who gets what, when, and how–central to our field and the keystone of a better way forward.

We test whether tissue moisture content affects settling and feeding behaviours of Monochamus galloprovincialis, a forest insect that feeds on multiple pine species and is a vector of tree disease. In a watering experiment using potted Aleppo pine trees, Pinus halepensis Miller (Pinaceae), water deprivation reduced mid-day shoot water potentials and corresponded to lower phloem water content. In short-term choice assays allowing prereproductive beetles to select among P. halepensis phloem for maturation feeding, beetles preferred to settle and initiate feeding on phloem with lower moisture content and over a 24-hour period consumed more phloem from oven-dried phloem punches. No differences in settling and feeding preferences between males and females were observed. In no-choice feeding assays where beetles were confined to either “dry” or “fresh” shoots (moisture differential ∼10%) over a five-day period, beetles fed on fresh shoots excreted on average 38% more frass, potentially consistent with higher consumption requirements. Our data suggest that water input affects shoot water potentials of Aleppo pine and corresponding phloem water content, which influences feeding preferences of newly emerged M. galloprovincialis.

Fire is a material and social process that is different in different periods and places. This article examines the fires set during the largest, and last, uprising of the enslaved in Jamaica, which occurred in the island's western parishes after Christmas 1831. It argues that different sorts of fire were central to processes of production and everyday life under plantation slavery, and examines what the burnings of 1831–32 reveal about the fight against enslavement in the early nineteenth century. A close reading of the records of the trials that followed the uprising details the methods used to burn plantations; the decisions over what to burn and what to save; and the contested social and political relations involved in encouraging or extinguishing the flames. This demonstrates that fire was a material means of creative destruction for the rebels that turned the everyday practices of commodity production and coerced social reproduction against the plantation infrastructure; that destroying buildings by fire both denied and made claims on the land, and sought to remake the Jamaican landscape for other forms of inhabitation; and that the collectivities forged through fire were inevitably shaped by both shared endeavors and tensions within and between groups of plantation inhabitants facing an uncertain future. Overall, it seeks to understand the use of fire in the 1831–32 uprising to fight for freedom as part of a “politics of habitation.”

Although the Lower Kasai was identified by Jan Vansina as a likely center for highly complex societies, he failed to recognize that sixteenth-century sources had mentioned the Empire of Mwene Muji as a large polity in that region. Studying the well known and recently discovered literature on West Central Africa, as well as a critical study of oral tradition, shows considerable evidence for the antiquity and existence of Mwene Muji.

A rise in the number of moral individuals in a group can hurt the morality of the group’s collective action. In this paper, we characterize strategic environments and models of morality where this is true solely because, after all, individual morals are private information.

The period 1974–1999 were transition years for government school systems in Australia and New South Wales (NSW), where government agencies issued numerous policies and documents to influence and manage education and resultant classroom pedagogy. During those years, many music syllabi were produced for enactment in NSW, placing multiple demands on teacher accountability. This paper forms part of a larger study involving three generations of music teachers representing different career stages and experiences and presents the voices of the group of experienced music teachers (EMTs), exploring the impact of syllabus change, teacher identity, pedagogical skills, and eventual flourishing as confident teachers.
