Macroeconomic data on the Spanish economy during the Second Republic is not accurate, the interpretation of historical events from the figures obtained is divergent and misleading. Hasty laws were enacted in attempts to resolve social problems arising mainly from deep economic inequalities, but they were often nothing more than declarations of good intentions. Spain suffered in the aftermath of the international economic downturn as it began to be felt at the end of the dictatorship of General Primo de Rivera. Economic policy was developed under the Constitution,but, despite the differences between the first and second biennium, there was a tendency to maintain the guidelines from the previous stage and in general, sometimes unfairly, it aimed at least to avoid the destabilization of the financial system. Nonetheless, it ultimately failed to achieve its goals, mainly because of the frequent changes of government mediated by a social crisis of greater significance that had relegated economic issues into the background.
We present the results of a comprehensive survey conducted among members of the Spanish Astronomical Society (Sociedad Espanola de Astronomia, SEA) to assess well-being, professional satisfaction, and family-work balance of researchers in astronomy. The survey addressed multiple aspects of professional life, including happiness, career stability, publication pressure, and access to childcare services during scientific meetings. Responses were examined across gender and career stages to identify trends and sources of dissatisfaction.
Stone duality establishes a contravariant equivalence between the category of Boolean algebras and the category of compact, Hausdorff, totally disconnected topological spaces (Stone spaces). These spaces are precisely the profinite spaces and form the natural environment for arithmetic objects such as the $p$-adic integers, absolute Galois groups, and profinite completions. In this article we give a rigorous and self-contained development of the construction of the Stone space associated to a Boolean algebra, prove Stone's representation theorem, and describe profinite spaces as inverse limits of finite systems. From there we introduce the Stone--Čech compactification via its universal property and discuss central arithmetic examples (such as $β\mathbb{N}$ and profinite completions), emphasizing their structural role in arithmetic geometry and in the framework of Condensed Mathematics of Clausen--Scholze. The text is aimed at advanced undergraduate and beginning graduate students, as well as readers interested in the interface between topology, number theory, and new categorical formulations of topology.
The current situation of open research data in Spanish university repositories is analyzed by means of twelve indicators that allow us to compare them with each other. The twelve self-developed indicators deal with research datasets and institutional policies linked to open access, as well as some of the key characteristics of the repositories. The methodology used consists of comparing the repositories of the different universities linked to REBIUN. The result has been that datasets in institutional repositories are scarce, and the situation is heterogeneous across the territory. This raises questions about future open access policies for research data in the country's main scientific institutions.
Climate change-associated disasters have become a significant concern, principally when affecting urban areas. Assessing these regions' resilience to strengthen their disaster management is crucial, especially in the areas vulnerable to windstorms, one of Spain's most critical disasters. Smart cities and machine learning offer promising solutions to manage disasters, but accurately estimating economic losses from windstorms can be difficult due to the unique characteristics of each region and limited data. This study proposes utilizing ML classification models to enhance disaster resilience by analyzing publicly available data on windstorms in the Spanish areas. This approach can help decision-makers make informed decisions regarding preparedness and mitigation actions, ultimately creating a more resilient urban environment that can better withstand windstorms in the future.
The aim of this paper is to carry out a systematic analysis of the literature to show the state of the art of Business Processes Management Systems (BPMS). BPMS represents a technology that automates business processes connecting users with their tasks. For this, a systematic review of the literature of the last ten years was carried out, using scientific papers indexed in the main databases of the knowledge area. The papers generated by the search were later analysed and filtered. Among the findings of this study, the academic interest and the multidisciplinary nature of the subject, as this type of studies have been identified in different areas of knowledge. Our research is a starting point for future research eager to develop a more robust theory and broaden the interest of the subject due its economic impact on process management.

Scientists have generated quantum entanglement directly from sunlight, potentially offering a lower-energy alternative to the lasers normally used in quantum technology。 Their outdoor experiment produced entangled photons with about 94% similarity to an ideal state。 The result could pave the way for simpler quantum satellites, secure communications
Researchers have found a way to build much larger “twisted” oxide materials while precisely controlling how their atomic layers line up。 Because these materials can be made over large areas and transferred onto different surfaces, the technique could help turn twistronics from a laboratory curiosity into a practical platform for next-generation ele
NASA’s Psyche spacecraft aced its Mars flyby, using the planet’s gravity to speed toward its 2029 encounter with a metal-rich asteroid。 The spacecraft tested its cameras, magnetometer, and particle-detecting instruments, capturing unusual views of Mars and measuring its magnetic environment。 It also detected neutrons from the planet and spotted the
A massive magma reservoir has been detected deep beneath Tuscany, despite showing no obvious signs at the surface。 Scientists mapped the roughly 6,000-cubic-kilometer body using natural ground vibrations recorded by dozens of seismic sensors。 It poses no immediate danger, but the discovery reveals how enormous volcanic systems can remain hidden and
