This study reviews the evolution of scientific research on climatic droughts in Spain over the last few decades. The complexity of this natural hazard and the wide incidence of droughts in Spain have led to great interest from scientists in Spain, and generated a significant amount of scientific work on the topic over the last two decades. Climatic drought studies have evolved from predominantly descriptive studies up to the 1990s to highly diverse research topics, which include the development of indices, tools and datasets, the study of drought hazard probability, the analysis of drought variability and trends, including research on long term drought reconstructions and analysis with instrumental data, an assessment of drought mechanisms and drivers, and drought modeling, including how models represent droughts, and applying models to drought forecasting and future projections. The study of climatic droughts in Spain is highly internationalized, since most of the current scientific studies are published in high-impact international journals and, nowadays, do not only cover Spain, but also other world regions as well as continental and global studies.

The use of 3D point clouds to improve the understanding of natural phenomena is currently applied in natural hazard investigations, including the quantification of rockfall activity. However, 3D point cloud treatment is typically accomplished using nondedicated (and not optimal) software. To fill this gap, we present an open-source, specific rockfall package in an object-oriented toolbox developed in the MATLAB® environment. The proposed package offers a complete and semiautomatic 3D solution that spans from extraction to identification and volume estimations of rockfall sources using state-of-the-art methods and newly implemented algorithms. To illustrate the capabilities of this package, we acquired a series of high-quality point clouds in a pilot study area referred to as the La Cornalle cliff (West Switzerland), obtained robust volume estimations at different volumetric scales, and derived rockfall magnitude–frequency distributions, which assisted in the assessment of rockfall activity and long-term erosion rates. An outcome of the case study shows the influence of the volume computation on the magnitude–frequency distribution and ensuing erosion process interpretation.

Experience plays a critical role in crafting high-impact scientific work. This is particularly evident in top multidisciplinary journals, where a scientist is unlikely to appear as senior author if he or she has not previously published within the same journal. Here, we develop a quantitative understanding of author order by quantifying this “chaperone effect,” capturing how scientists transition into senior status within a particular publication venue. We illustrate that the chaperone effect has a different magnitude for journals in different branches of science, being more pronounced in medical and biological sciences and weaker in natural sciences. Finally, we show that in the case of high-impact venues, the chaperone effect has significant implications, specifically resulting in a higher average impact relative to papers authored by new principal investigators (PIs). Our findings shed light on the role played by experience in publishing within specific scientific journals, on the paths toward acquiring the necessary experience and expertise, and on the skills required to publish in prestigious venues.

Three new species of Collembola are described from small shallow caves in Southeastern Brazil: Arrhopalites glabrofasciatus sp. nov., Pseudosinella ambigua sp. nov. and Pseudosinella guanhaensis sp. nov. The species were found in surveys performed as part of the process to accomplish the permits for high impact enterprising. The change in the legislation is discussed and a suggestion is made to improve the process. The long term effects of the law resulted in the discovery of many new species and genera, most of them being (or to be) described.

Introduction. The aim of the study was to use trajectory analysis to categorise high-impact users based on their long-term readmission rate and identify their predictors following AAA (abdominal aortic aneurysm) repair. Methods. In this retrospective cohort study, group-based trajectory modelling (GBTM) was performed on the patient cohort (2006-2009) identified through national administrative data from all NHS English hospitals. Proc Traj software was used in SAS program to conduct GBTM, which classified patient population into groups based on their annual readmission rates during a 5-year period following primary AAA repair. Based on the trends of readmission rates, patients were classified into low- and high-impact users. The high-impact group had a higher annual readmission rate throughout 5-year follow-up. Short-term high-impact users had initial high readmission rate followed by rapid decline, whereas chronic high-impact users continued to have high readmission rate. Results. Based on the trends in readmission rates, GBTM classified elective AAA repair (n=16,973) patients into 2 groups: low impact (82.0%) and high impact (18.0%). High-impact users were significantly associated with female sex (P=0.001) undergoing other vascular procedures (P=0.003), poor socioeconomic status index (P<0.001), older age (P<0.001), and higher comorbidity score (P<0.001). The AUC for c-statistics was 0.84. Patients with ruptured AAA repair (n=4144) had 3 groups: low impact (82.7%), short-term high impact (7.2%), and chronic high impact (10.1%). Chronic high impact users were significantly associated with renal failure (P<0.001), heart failure (P = 0.01), peripheral vascular disease (P<0.001), female sex (P = 0.02), open repair (P<0.001), and undergoing other related procedures (P=0.05). The AUC for c-statistics was 0.71. Conclusion. Patients with persistent high readmission rates exist among AAA population; however, their readmissions and mortality are not related to AAA repair. They may benefit from optimization of their medical management of comorbidities perioperatively and during their follow-up.

AbstractThe paper’s conceptual framework is the United Nations Agenda 2030 and the long-term Sustainable Development Goals. Scientific work on environmental issues has underlined the urgency and profoundness of the transformations needed to achieve the COP21 global warming thresholds in the short time left. Despite the systemic character of sustainability, most suggested innovation policies do not consider the advantages of an integrated view of environmental and social issues. The paper explores this possibility by analysing the chances of minor centres (small towns and peripheral communities) to combine these challenges in sustainable development models. Transformative innovation steps inspired by the responsible innovation approach are vital instruments to reach that goal. The paper’s conjecture about the minor centres is supported by analysing three main courses in the sustainability route: the conversion to renewable energy, the circular economy, and the digitalisation process. The analysis offers innovation hints for the responsible development of plans such as the Next Generation EU, launched to support Europe’s economic revival in the post-pandemic phase.

This article proposes a duplex theory for understanding the scientific impact of contributions to psychological science. I argue that articles that we “love” can be understood in terms of (a) triangular elements of intimacy, passion, and commitment and (b) types of stories that characterize high-impact articles. Certain kinds of stories (e.g., review articles) are more likely to have lasting impact, on average, than other kinds of stories (e.g., data-driven empirical articles).

The Great Patriotic War was a decisive challenge not only for the military power and material and technical base of our country, but also for its spiritual, cultural and ideological foundations. Many Russian philosophers became participants in the hos­tilities, but the role of philosophers who continued scientific work was no less im­portant, the plans of which were adjusted and aimed at implementing projects re­lated to the strengthening of patriotism, the development of national identity, the revival of the classical forms of science and culture, consistent with historical heritage of Russia. This scientific work was in the context of the socio-cultural and spiritual processes that intensified in the USSR during the war and responded to the tasks of strengthening defense capability and the formation of a new socio-state identity. The main undertakings implemented in this connection by the Institute of Philosophy of the USSR Academy of Sciences were the development of the history of Russian philosophical thought and the creation of a new textbook of formal logic. These areas of research activity have shown their relevance in the light of the chal­lenges of wartime and prospects in terms of the long-term development of science.
