In the nineteenth century, the Dutch established time signals in their Atlantic colonies to synchronise maritime navigation with European standards. In Paramaribo (Suriname), a sophisticated sequence of apparatus -- including time balls, noon guns, discs and flags -- operated from 1851 until World War I. Naval officers aboard guard ships used sextants equipped with artificial horizons to determine local noon, thus integrating the colony into the global Greenwich-based cartographic system. This infrastructure was not merely technical; it became a civic ritual, with the daily noon gun structuring urban life and becoming a point of political negotiation between naval commanders and the colonial governor. In contrast, the Dutch Caribbean islands employed simpler, pragmatic systems. Curaçao used a daily time flag, a cost-effective solution suited to its climate and harbour scale, while smaller islands like Aruba and St. Eustatius relied on occasional noon guns. This diversity reflected a decentralised colonial administration that adapted technologies to local conditions and budgets. The history of these time signals reveals a process of hybrid adaptation, not simply replication of European models. They were shaped by environmental challenges, fiscal constraints and local politics, functioning simultaneously as navigational aids and civic landmarks. Their eventual decline, owing to budgetary pressures and new technologies like wireless telegraphy, underscores the fragile and negotiated nature of colonial scientific infrastructures.
This study provides a comparative analysis of the teaching workload of physical education and sport (PES) teachers in 17 countries across Central, Eastern, and South-Eastern Europe: Romania, Hungary, Poland, Czechia, Bulgaria, Estonia, Lithuania, Latvia, Serbia, Greece, Slovakia, Slovenia, Albania, Montenegro, North Macedonia, Croatia, and Bosnia and Herzegovina. The research highlights significant differences between countries with sustainable educational policies (Estonia, Slovenia, Greece, Czechia, Croatia) and those where teachers are overburdened and poorly supported (Romania, Bulgaria, Albania, North Macedonia, Bosnia and Herzegovina). The results show that teaching workload varies between 16 and 21 hours per week, directly impacting teaching quality, teacher health, and the social prestige of the discipline. Positive models are characterized by reduced workloads (16–17 hours), official recognition of extracurricular activities, and investments in modern infrastructure. In contrast, high workloads (19–21 hours), combined with the lack of recognition of invisible work, lead to professional fatigue, demotivation, and lower quality of education.

Language models have led to a leap forward in web automation. The current web automation approaches take the current web state, history actions, and language instruction as inputs to predict the next action, overlooking the importance of history states. However, the highly verbose nature of web page states can result in long input sequences and sparse information, hampering the effective utilization of history states. In this paper, we propose a novel web history compressor approach to turbocharge web automation using history states. Our approach employs a history compressor module that distills the most task-relevant information from each history state into a fixed-length short representation, mitigating the challenges posed by the highly verbose history states. Experiments are conducted on the Mind2Web and WebLINX datasets to evaluate the effectiveness of our approach. Results show that our approach obtains 1.2-5.4% absolute accuracy improvements compared to the baseline approach without history inputs.
This paper explores the potential of contextualized word embeddings (CWEs) as a new tool in the history, philosophy, and sociology of science (HPSS) for studying contextual and evolving meanings of scientific concepts. Using the term "Planck" as a test case, I evaluate five BERT-based models with varying degrees of domain-specific pretraining, including my custom model Astro-HEP-BERT, trained on the Astro-HEP Corpus, a dataset containing 21.84 million paragraphs from 600,000 articles in astrophysics and high-energy physics. For this analysis, I compiled two labeled datasets: (1) the Astro-HEP-Planck Corpus, consisting of 2,900 labeled occurrences of "Planck" sampled from 1,500 paragraphs in the Astro-HEP Corpus, and (2) a physics-related Wikipedia dataset comprising 1,186 labeled occurrences of "Planck" across 885 paragraphs. Results demonstrate that the domain-adapted models outperform the general-purpose ones in disambiguating the target term, predicting its known meanings, and generating high-quality sense clusters, as measured by a novel purity indicator I developed. Additionally, this approach reveals semantic shifts in the target term over three decades in the unlabeled Astro-HEP Corpus, highlighting the emergence of the Planck space mission as a dominant sense. The study underscores the importance of domain-specific pretraining for analyzing scientific language and demonstrates the cost-effectiveness of adapting pretrained models for HPSS research. By offering a scalable and transferable method for modeling the meanings of scientific concepts, CWEs open up new avenues for investigating the socio-historical dynamics of scientific discourses.
Understanding teachers' perspectives on AI in Education (AIEd) is crucial for its effective integration into the educational framework. This paper aims to explore how teachers currently use AI and how it can enhance the educational process. We conducted a cross-national study spanning Greece, Hungary, Latvia, Ireland, and Armenia, surveying 1754 educators through an online questionnaire, addressing three research questions. Our first research question examines educators' understanding of AIEd, their skepticism, and its integration within schools. Most educators report a solid understanding of AI and acknowledge its potential risks. AIEd is primarily used for educator support and engaging students. However, concerns exist about AI's impact on fostering critical thinking and exposing students to biased data. The second research question investigates student engagement with AI tools from educators' perspectives. Teachers indicate that students use AI mainly to manage their academic workload, while outside school, AI tools are primarily used for entertainment. The third research question addresses future implications of AI in education. Educators are optimistic about AI's potential to enhance educational processes, particularly through personalized learning experiences. Nonetheless, they express significant concerns about AI's impact on cultivating critical thinking and ethical issues related to potential misuse. There is a strong emphasis on the need for professional development through training seminars, workshops, and online courses to integrate AI effectively into teaching practices. Overall, the findings highlight a cautious optimism among educators regarding AI in education, alongside a clear demand for targeted professional development to address concerns and enhance skills in using AI tools.
Understanding how cooperation emerges in public goods games is crucial for addressing societal challenges. While optional participation can establish cooperation without identifying cooperators, it relies on specific assumptions -- that individuals abstain and receive a non-negative payoff, or that non-participants cause damage to public goods -- which limits our understanding of its broader role. We generalize this mechanism by considering non-participants' payoffs and their potential direct influence on public goods, allowing us to examine how various strategic motives for non-participation affect cooperation. Using replicator dynamics, we find that cooperation thrives only when non-participants are motivated by individualistic or prosocial values, with individualistic motivations yielding optimal cooperation. These findings are robust to mutation, which slightly enlarges the region where cooperation can be maintained through cyclic dominance among strategies. Our results suggest that while optional participation can benefit cooperation, its effectiveness is limited and highlights the limitations of bottom-up schemes in supporting public goods.
For a long time, Julius Africanus’ Chronicle has only been known through hundreds of fragments scattered across Greek, Latin and Oriental (Syriac, Arabic, and Armenian) manuscripts. About fifteen years ago, a long and coherent Slavonic excerpt from Africanus’ Chronicle was found in a chronographic compilation that survives in the five Russian witnesses of the 15th–16th centuries. The compilation has been erroneously identified as a Slavic translation of an abridged version of the Chronicle of George Synkellos. The excerpt contains Africanus’ main narrative devoid of the pre-Olympic history of nations except for the history of the Judeans. Taking up about two thirds of the whole text, it covers the years from the Creation to Christ’s Resurrection. The compilers complemented it with an excerpt from a common edition of the Chronicles of George Synkellos and Theophanes the Confessor, thus taking their account to the foundation of Constantinople. Created most likely in Greece, the Compilation was translated in the early 10th century in Bulgaria, during the reign of Simeon the Great, only a few decades after the nation’s conversion to Christianity. This paper analyses the periphrastic practices of the Bulgarian translators who had to adequately render the biblical and non-biblical toponyms, adapting them to the Old Bulgarian phonetics and morphology. The analysis is complicated by the fact that the Greek original of the
Compilation has been lost (or has not yet been identified). In order to identify the toponyms and their meanings, the author, where appropriate, makes use of parallels from the Septuagint and the Chronicle of Synkellos. The analysis shows that the Bulgarian translator/s had a good command of Greek and a good knowledge of the biblical geography – the number of correctly translated toponyms exceeds the number of those that were misspelled (the misspellings probably occurred during the long text transmission).

Neural Language Models (LMs) offer an exciting solution for general-purpose embodied control. However, a key technical issue arises when using an LM-based controller: environment observations must be converted to text, which coupled with history, results in long and verbose textual prompts. As a result, prior work in LM agents is limited to restricted domains with small observation size as well as minimal needs for interaction history or instruction tuning. In this paper, we introduce diff history, a simple and highly effective solution to these issues. By applying the Unix diff command on consecutive text observations in the interaction histories used to prompt LM policies, we can both abstract away redundant information and focus the content of textual inputs on the salient changes in the environment. On NetHack, an unsolved video game that requires long-horizon reasoning for decision-making, LMs tuned with diff history match state-of-the-art performance for neural agents while needing 1800x fewer training examples compared to prior work. Even on the simpler BabyAI-Text environment with concise text observations, we find that although diff history increases the length of prompts, the representation it provides offers a 25% improvement in the efficiency of low-sample instruction tuning. Further, we show that diff history scales favorably across different tuning dataset sizes. We open-source our code and data to https://diffhistory.github.io.
Since the beginning of the 20th century, a continuous evolution and perfection of what we today call the standard cosmological model has been produced, although some authors like to distinguish separate periods within this evolution. A possible historical division of the development of cosmology into six periods is: (1) the initial period (1917-1927); (2) the period of development (1927-1945); (3) the period of consolidation (1945-1965); (4) the period of acceptance (1965-1980); (5) the period of enlargement (1980-1998); and (6) the period of high-precision experimental cosmology (1998-now). The last period started with a epistemological optimism that has declined with time, and the expression "crisis in cosmology" is now stubbornly reverberating in the media. The initial expectation of removing the pending minor problems arising from the increased accuracy of measurements has backfired: the higher the precision with which the standard model tries to fit the data, the greater the number of tensions that arise, the problems proliferating rather than diminishing.
Greece has a variety of cheeses that are registered as protected designation of origin and protected geographical indications, and many others that are produced in a traditional way, without such registration. This article aims to describe the characteristics of these cheeses, which do not bear a certification of geographical indication, in order to increase their significance. Therefore, in this work, the scientific data published about the history, production, composition, and other specific properties of some milk cheeses (Kariki, hard Xinotyri, soft Xinotyri, Kefalotyri, Kashkaval Pindos, Graviera, Manoura Sifnos, Teleme, Tsalafouti, Tyraki Tinou, Ladotyri Zakynthou, Touloumotyri, and Melichloro) and whey cheeses (Anthotyros, Myzithra, and Urda) are presented. This information may contribute to their better promotion and recognition, protecting their heritage, and supporting the local economy.
Constraints on the Higgs boson self-coupling are set by combining double-Higgs boson analyses in the bb¯bb¯, bb¯τ+τ− and bb¯γγ decay channels with single-Higgs boson analyses targeting the γγ, ZZ⁎, WW⁎, τ+τ− and bb¯ decay channels. The data used in these analyses were recorded by the ATLAS detector at the LHC in proton–proton collisions at s=13 TeV and correspond to an integrated luminosity of 126–139 fb−1. The combination of the double-Higgs analyses sets an upper limit of μHH<2.4 at 95% confidence level on the double-Higgs production cross-section normalised to its Standard Model prediction. Combining the single-Higgs and double-Higgs analyses, with the assumption that new physics affects only the Higgs boson self-coupling (λHHH), values outside the interval −0.4<κλ=(λHHH/λHHHSM)<6.3 are excluded at 95% confidence level. The combined single-Higgs and double-Higgs analyses provide results with fewer assumptions, by adding in the fit more coupling modifiers introduced to account for the Higgs boson interactions with the other Standard Model particles. In this relaxed scenario, the constraint becomes −1.4<κλ<6.1 at 95% CL.
Introduction
Transhistorical psychiatry defends that a psychic alteration can be interpreted as a cultural, historical and personal construction, subject to incessant variations.
Objectives
A journey through the history of the disorder and the successive pathomorphoses it has undergone could provide us with a better understanding of it and explain the reason for the epidemiological trend towards a decrease in its diagnosis; and bring us closer to a universal definition of the phenomenon.

The word hysteria and all its subsequent meanings, not only contain a particular conception of the pathology, but also reflect its different forms of presentation in specific periods of time. Hysteria is presented as a voluble material that can take on any form: from the wandering womb theory of classical Greece to the demonic possessions of the Middle Ages; from the neurological degeneration of Charcot (1825-1893) to the conversion and dissociation of Freud (1856-1939). With the entry of the 20th century, its dramatic clinic has been progressively overshadowed by somatoform disorders and emerging functional somatic syndromes. Today, it is practically unrecognisable and very difficult to diagnose, to the point of having disappeared as a term from the official classifications of our time.
Conclusions
Hysteria is an entity that has not always been the same, neither in its conception nor in its manifestations. Depending on the socio-cultural context in which it is framed, it will be interpreted and expressed in different ways.

A priori, there is a “tension” between the principles of Stoic philosophy, which include a rejection of anything in rhetoric that deviates from a pure and hard dialectic, and the cultural environment where Arrien and Epictetus evolved, where rhetoric was omnipresent, and this from the initial training. The purpose of this article is to analyze the manifestations of this presence of rhetoric in Book 3 of the Discourses, both as a traditional target of criticism and as an instrument of an extremely sophisticated pedagogy.
Alexander the Great (356 B.C – 323 B.C) has gone down in history as one of the greatest conquerors of Antiquity. By the time he was 30, he had conquered most of the known world. The territory under his control lay from Greece in the west, southward through Egypt and eastward to India. His military successes made him an inspiration to many writers of his time and later. Since his life span corresponds to the era that today we call Hellenism, he is mentioned in all the educational systems of Europe. From their first appearance on this continent, school books have alluded to Alexander and his conquests. The first history textbooks in the Serbian language emerged in Serbia in the mid-19th century and they, too, included Alexander the Great. In this paper, we shall show how the history of Alexander was taught at the time and how his feats influenced generations of Serbian children educated at the first schools founded in the areas of the Habsburg Empire that they inhabited.

The structure of an evolving network contains information about its past. Extracting this information efficiently, however, is, in general, a difficult challenge. We formulate a fast and efficient method to estimate the most likely history of growing trees, based on exact results on root finding. We show that our linear-time algorithm produces the exact stepwise most probable history in a broad class of tree growth models. Our formulation is able to treat very large trees and therefore allows us to make reliable numerical observations regarding the possibility of root inference and history reconstruction in growing trees. We obtain the general formula $\langle \ln \mathcal{N} \rangle \cong N \ln N - cN$ for the size-dependence of the mean logarithmic number of possible histories of a given tree, a quantity that largely determines the reconstructability of tree histories. We also reveal an uncertainty principle: a relationship between the inferrability of the root and that of the complete history, indicating that there is a tradeoff between the two tasks; the root and the complete history cannot both be inferred with high accuracy at the same time.
The concept of indistinguishable particles in quantum theory is fundamental to questions of ontology. All ordinary matter is made of electrons, protons, neutrons, and photons and they are all indistinguishable particles. Yet the concept itself has proved elusive, in part because of the interpretational difficulties that afflict quantum theory quite generally, and in part because the concept was so central to the discovery of the quantum itself, by Planck in 1900; it came encumbered with revolution. I offer a deflationary reading of the concept "indistinguishable" that is identical to the Gibbs concept of "generic phase", save that it is defined for state spaces with only finitely-many states of bounded volume and energy (finitely-many orthogonal states, in quantum mechanics). That, and that alone, makes for the difference between the quantum and Gibbs concepts of indistinguishability. This claim is heretical on several counts, but here we consider only the content of the claim itself, and its bearing on the early history of quantum theory rather than in relation to contemporary debates about particle indistinguishability and permutation symmetry. It powerfully illuminates that history.
Conversational search is an emerging topic in the information retrieval community. One of the major challenges to multi-turn conversational search is to model the conversation history to answer the current question. Existing methods either prepend history turns to the current question or use complicated attention mechanisms to model the history. We propose a conceptually simple yet highly effective approach referred to as history answer embedding. It enables seamless integration of conversation history into a conversational question answering (ConvQA) model built on BERT (Bidirectional Encoder Representations from Transformers). We first explain our view that ConvQA is a simplified but concrete setting of conversational search, and then we provide a general framework to solve ConvQA. We further demonstrate the effectiveness of our approach under this framework. Finally, we analyze the impact of different numbers of history turns under different settings to provide new insights into conversation history modeling in ConvQA.
Identity studies live. This latest batch of publications explores what made not just the Romans but the Italians, Christians, and Etruscans who they were. We begin with both age and beauty, the fruits of a special exhibition at the Badischen Landesmuseum Karlsruhe in the first half of 2018 into the most famous of Roman predecessors, the Etruscans. Most of the exhibits on display come from Italian museums, but the interpretative essays that break up the catalogue – which are also richly illustrated – are by both Italian and German scholars. These are split between five overarching sections covering introductory affairs, the ages of the princes and of the city-states, the Etruscans’ relationship with Rome, and modern reception. The first contains essays treating Etruscan origins, history, identity, and settlement area. The second begins with the early Iron Age Villanova site, before turning to early Etruscan aristocratic culture, including banqueting, burials, language, writing, and seafaring. The third and longest section considers the heyday of Etruscan civilization and covers engineering and infrastructure, crafts and production, munitions, women's roles, daily life, dance, sport, funerary culture, wall painting, religious culture, and art. The fourth section treats both the confrontation between Etruscan and Roman culture and the persistence of the former after ‘conquest’ by the latter. The fifth section contains one essay on the modern inheritance of the Etruscan ‘myth’ and one on the history of scholarship on the Etruscans. Three aspects to this volume deserve particular praise. First, it includes not only a huge range of material artefacts but also individual essays on Etruscan production in gold, ceramic, ivory, terracotta, and bronze. Second, there is a recurring interest in the interconnections between the Etruscans and other cultures, not just Romans but Greeks, Iberians, Celts, Carthaginians, and other Italian peoples. Third, it includes the history of the reception of Etruscan culture. Amid the just-shy-of-200 objects included (almost every one with description and high-quality colour image), the reader can find everything from a mid-seventh-century pitcher made from an Egyptian ostrich egg painted with birds, flowers, and dancers (147), through the well-known third- or second-century bcTabula Cortonensis – a lengthy and only partially deciphered Etruscan inscription that documents either a legal transaction or a funerary ceremony (311) – to the 2017 kit of the Etruschi Livorno American Football team (364). Since we have no extant Etruscan literature, a volume such as this is all the more valuable in trying to get a sense of these people and their culture, and the exceptionally high production value provides quality exposure to material otherwise scattered throughout Italy.
