In recent work [quant-ph/0405174] by Schumacher and Werner was discussed an abstract algebraic approach to a model of reversible quantum cellular automata (CA) on a lattice. It was used special model of CA based on partitioning scheme and so there is a question about quantum CA derived from more general, standard model of classical CA. In present work is considered an approach to definition of a scheme with "history", valid for quantization both irreversible and reversible classical CA directly using local transition rules. It is used language of vectors in Hilbert spaces instead of C*-algebras, but results may be compared in some cases. Finally, the quantum lattice gases, quantum walk and "bots" are also discussed briefly.

ESG reporting is a key process through which companies provide detailed information regarding their impact on the environment (E), society (S) and corporate governance (G). The aim of the article is to present the authors' research results on the reporting of environmental information in the field of ESG among companies from the energy sector and the defence industry, represented by the example of PIT-RADWAR, listed on the Warsaw Stock Exchange in 2022-2023. The methodology was based on a review of the literature on the subject, legal acts and own research, which used non-financial reports of listed companies regarding ESG information. According to the authors, the article adds value to the literature on the subject, in particular in terms of gathering source material and discussing it. Considering the growing importance of ESG factors in the defence sector, the article also highlights the emerging trend of ESG reporting in this industry using the example of PIT-RADWAR S.A., emphasising its growing importance and the sector's first steps towards increasing the transparency of non-financial reporting. The subject matter of the article can form the basis for further detailed empirical research on ESG reporting.

Ernst Haeckel (1834-1919) foi um renomado pesquisador alemão da segunda metade do século XIX e início do século XX. Parte de sua produção científica foi devotada a defender e divulgar as ideias darwinianas de modificação das espécies em seu país. Entre as ideias de Haeckel, destaca-se a Lei Biogenética Fundamental, na qual ele afirmava que os estágios de desenvolvimento pelos quais passam os embriões recapitulam a história evolutiva do filo. Para explicar essa ideia, na obra Natürliche Schöpfungsgeschichte (História Natural da Criação) de 1868, Haeckel utilizou ilustrações de embriões que foram alvo de críticas e acusações de fraude e plágio. Este artigo tem por objetivos analisar o uso que Ernst Haeckel fez dessas ilustrações, relatando algumas das críticas de cientistas contemporâneas e posteriores e proporcionar um material para atividades pedagógicas voltadas ao ensino de evolução biológica e desenvolvimento embrionário. Em aproximação a análises realizadas por alguns historiadores da ciência, conclui-se que Haeckel se defendeu razoavelmente e que a motivação maior das críticas era o ataque ao darwinismo.

This article offers a new perspective on children and youth’s coerced displacement in the context of the Ottoman Middle East and highlights their potential as a social group to inform studies of children, kinship, and family vis-a-vis the state. Using iltizām contracts, I argue that the Ottoman state prioritized its stability and economic interests and turned a blind eye to promises it made to ensure the “well-being” of young Ottoman subjects. The contracts recorded around the mid-eighteenth century document an institutionalized practice by the state to remove and incarcerate young and minor males associated with the families of multazims, or tax farmers, who generally hailed from the class of provincial notables, or a‘yān, to persuade the latter to render payment of taxes. Although multazims appeared to be indifferent to the fate of their castaway children, evidence suggests that multazims took advantage of geopolitical changes toward the last quarter of the eighteenth century to avoid the incarceration of their children, as the practice completely disappeared at that time. This article also attempts to approach the question of whether this forced displacement of children represents a form of mobility, in comparison to other forms of children’s mobility, like the devširme, and explores what this meant for the expansion, or retraction, of the state power and its governing policies.

The southern Mediterranean region, particularly North Africa, is a crucial area for biodiversity conservation. However, the impacts of climate change on plant species in this region are not well understood. Dendroecology, the study of tree rings, is a valuable technique for analyzing the effects of environmental changes on woody plants over time. In this study, we intend to assess the state of the art in dendrochronological research in North Africa and identify knowledge gaps and limitations in the field. The period of analysis spans from 1979 to 2023. We used all the available literature in Dendrobox and Google Scholar during this period. Our study revealed several research gaps in the region, including the need for more studies on the history of forest fires and their relationship to climate conditions in Morocco, Algeria, and Tunisia, the impact of climate on the anatomical characteristics of growth rings, and the effects of climate change on tree species diversity and forest health. Applying this technique in the future would allow for detailed insights into the effect of climate on the internal structure and growth of forest trees. The findings of this study will help guide future research and contribute to a better understanding of the climate-growth relationship of woody plants in North Africa.

Dynamic Stochastic General Equilibrium (DSGE) models are nowadays a crucial quantitative tool for policy-makers. However, they did not emerge spontaneously. They are built upon previously established ideas in Economics and relatively recent advancements in Mathematics. This essay provides a comprehensive coverage of their history, starting from the pioneering Neoclassical general equilibrium theories and eventually reaching the New Neoclassical Synthesis (NNS). In addition, the mathematical tools involved in formulating a DSGE model are thoroughly presented. I argue that this history has a mixed nature rather than an absolutist or relativist one, that the NNS may have emerged due to the complementary nature of New Classical and New Keynesian theories, and that the recent adoption and development of DSGE models by central banks from different countries has entailed a departure from the goal of building a universally valid theory that Economics has always had. The latter means that DSGE modeling has landed not without loss of generality.
