Abstract. The dependence of rainfall on elevation has frequently been documented in the scientific literature and may be relevant in Italy, due to the high degree of geographical and morphological heterogeneity of the country. However, a detailed analysis of the spatial variability of short-duration rainfall extremes and their connection to the landforms does not exist. Using a new, comprehensive and position-corrected rainfall extreme dataset (I2-RED), we present a systematic study of the relationship between geomorphological forms and the average of rainfall extremes (index rainfall) across the whole of Italy. We first investigated the dependence of sub-daily rainfall depths on elevation and other landscape indices through univariate and multivariate linear regressions. After analyzing the results, we repeated the analysis on geomorphological subdivisions of Italy. The results of the national-scale regression analysis did not confirm the assumption of elevation being the sole driver of the variability of rainfall extremes. The longitude, latitude, distance from the coastline, morphological obstructions and mean annual rainfall resulted to be significantly related to the index rainfall, and to play different roles for different durations (1- to 24-hours). However, when comparing the results of the best multivariate regression models with univariate regressions for morphological subdivisions, we found that “local” rainfall-topography relationships within the geomorphological subdivisions outperformed the country-wide multiple regressions and offered a reasonable representation of the effect of morphology on rainfall extremes.

Abstract. Historical in situ sub-daily rainfall observations are essential for the understanding of short-duration rainfall extremes but records are typically not readily accessible and data are often subject to errors and inhomogeneities. Furthermore, these events are poorly quantified in projections of future climate change making adaptation to the risk of flash flooding problematic. Consequently, knowledge of the processes contributing to intense, short-duration rainfall is less complete compared with those on daily timescales. The INTENSE project is addressing this global challenge by undertaking a data collection initiative that is coupled with advances in high-resolution climate modelling to better understand key processes and likely future change. The project has so far acquired data from over 23 000 rain gauges for its global sub-daily rainfall dataset (GSDR) and has provided evidence of an intensification of hourly extremes over the US. Studies of these observations, combined with model simulations, will continue to advance our understanding of the role of local-scale thermodynamics and large-scale atmospheric circulation in the generation of these events and how these might change in the future.

<p>The intensity and the spatial distribution of precipitation depths are known to be highly dependent on relief and geomorphological parameters. Complex environments like mountainous regions are prone to intense and frequent precipitation events, especially if located near the coastline. Although the link between the mean annual rainfall and geomorphological parameters has received substantial attention, few literature studies investigate the relationship between the sub-daily maximum annual rainfall depth and geographical or morphological landscape features.<br>In this study, the mean of the rainfall extremes in Italy, recently revised in the so-called I<sup>2</sup>-RED dataset, are investigated in their spatial variability in comparison with some landscape and also some broad climatic characteristics. The database includes all sub-daily rainfall extremes recorded in Italy from 1916 until 2019 and this analysis considers their mean values (from 1 to 24 hours) in stations with at least 10 years of records, involving more than 3700 stations.<br>The geo-morpho-climatic factors considered range from latitude, longitude and minimum distance from the coastline on the geographic side, to elevation, slope, openness and obstruction morphological indices, and also include an often-neglected robust climatological information, as the local mean annual rainfall.<br>Obtained results highlight that the relationship between the annual maximum rainfall depths and the hydro-geomorphological parameters is not univocal over the entire Italian territory and over different time intervals. Considering the whole of Italy, the highest correlation is reached between the mean values of the 24-hours records and the mean annual precipitation (correlation coefficient greater than 0.75). This predominance remains also in sub-areas of the Italian territory (i.e., the Alpine region, the Apennines or the coastal areas) but correlation decreases as the time interval decreases, except for the Alpine region (0.73 for the 1-hour maximum). The other geomorphological parameters seem to act in conjunction, making it difficult to evaluate, with a simple linear regression analysis, their impact. As an example, the absolute value of the correlation coefficient between the elevation and the 1-hour extremes is greater than 0.35 for the Italian and the Alpine regions, while for the 24-hours interval it is greater than 0.35 over the coastal areas.<br>To further investigate the spatial variability of the relationship between rainfall and elevation, a spatial linear regression analysis has been undertaken. Local linear relationships have been fitted in circles centered on any of the 0.5-km size pixels in Italy, with 1 to 30 km radius and at least 5 stations included. Results indicate the need of more comprehensive terrain analysis to better understand the causes of local increasing or decreasing relations, poorly described in the available literature.</p>

The article is devoted to the consideration of the history of the development of the system of diocesan administrations of the unrecognized Belarusian Autocephalous Orthodox Church (BAOC). Formed in 1948–1949, the named religious organization over the next several decades was an influential center for the consolidation of the Belarusian post-war Diaspora. The activities of the parishes of the BAOC were not limited to the organization of services and involved the conduct of social, cultural, educational, publishing and other work. In turn, the control, management and coordination of parish activities largely depended on the principles of organizing diocesan administration. On the basis of the study, it is concluded that the volume of administrative powers of the episcopate is gradually reduced and the role of the laity in the administration of dioceses is strengthened. The noted instability of the diocesan structures of the BAOC in the period under review is explained by the high degree of dependence of the diocesan affiliation of parishes on the relationship with a particular hierarch.

The aim of the study is twofold. On the one hand it concerns the measurement and the examination of the subjects’ self-concept and on the other the detection and justification of the role of family in its configuration. The study analyzed the data collected from the answers to a research questionnaire of 1344 15-and 16-year-old school students in the Prefecture of Thessaloniki, Greece) with the use of a stratified random sampling technique. The first important finding concerned the high degree of the general self-concept of the adolescents. Among the seven specific sectors of the general self-concept a major variation was noted, with the higher average to be traced in the relationship that the students have configured with their peers and the lower one in the valuation of their academic competence. The second important finding was the ascertainment of the essential contribution of the family.

<p>Trends are customarily identified in rainfall data in the framework of explanatory modelling. Little insight however has been gained by this type of analysis with respect to their performance in foresight. In this work, we examine the out-of-sample predictive performance of linear trends through extensive investigation of 60 of the longest daily rainfall records available worldwide. We devise a systematic methodological framework in which linear trends are compared to simpler mean models, based on their performance in predicting climatic-scale (30-year) annual rainfall indices, i.e. maxima, totals, wet-day average and probability dry, from long-term daily records. Parallel experiments from synthetic timeseries are performed in order to provide theoretical insights to the results and the role of parsimony in predictive modelling is discussed. In line with the empirical findings, it is shown that, prediction-wise, simple is preferable to trendy.</p>

Abstract Could the environmental regulation promote green innovation? This is a very controversial issue. In view of the fact that the existing literature only studies the relationship between the two, lacks effective heterogeneity research, and pays less attention to the deeper analysis mechanism between the two. This study fills the gap. This paper selects the panel data of 285 prefecture level cities in China from 2000 to 2019 for empirical research. The results show that environmental regulation has a significant and continuous positive impact on green innovation.From the perspective of heterogeneity, we find that cities with higher level of green innovation are suitable to improve the intensity of environmental regulation; Cities with low level of green innovation can not formulate high-intensity environmental regulation policies. The intermediary mechanism shows that under the situation of stricter environmental regulations, producers will pay more attention to the promotion and accumulation of human capital, and provide strong intellectual support for green innovation activities. The adjustment mechanism shows that the cities with high degree of marketization and financial R&D investment are conducive to strengthening the promotion of environmental regulation on green innovation. On the contrary, it weakens the role of environmental regulation in promoting green innovation. In addition, this paper uses SYS-GMM model and selects appropriate instrumental variables to solve the endogeneity problem of the model. We find that after reducing the endogeneity of the model, improving the intensity of environmental regulation can still promote the level of green innovation. Using SDM decomposition model, we find that environmental regulation has spatial spillover effect on green innovation, and the formulation of environmental regulation strategy is conducive to the coordinated development of regional green innovation.

The pastoral trips of Pope Francis to Cuba and to the United States were not only religious. The political activity that he organized to consolidate the relationship between the two recently reconciled countries was remarkable. Through visits, meetings and masses the Pope expressed his position and concerns about various arguments, beyond the recomposed Cuban-American relationship. During the trip he addressed subjects including the environment, poverty, family, union, freedom, all of which were themes that the Pontiff had clearly stated in his encyclical Laudato Si ‘(2015) and his Apostolic Exhortation Evangelii Gaudium (2013). With this trip, Pope Francis ended up consolidating his status as a global politician as well as a pastor with a high degree of acceptance not only among Catholics.

The interpretation of the concept of idiomatization and the related concept of phraseologization was performed by analyzing the process of metaphorical reinterpretation of the collocation (a phraseological unit with partial reinterpretation) resulting in the formation of an idiom (a phraseological unit with a high degree of reinterpretation). In this paper, idiomatization is regarded as the process of reinterpretation of a collocation. The interpretation of the concepts of idiomatization and phraseologization was clarified. The object of research is German idioms, which emerged from collocations that have undergone a semantic shift. Common collocations do not always undergo the reinterpretation process. Therefore, there is no direct dependence between their idiomatization and usage frequency. In addition, language unobservability does not always provide an accurate image of the diachronic changes that a particular collocation is subject to. In this regard, the question was raised about the relationship between the concepts of development and reproducibility (frequency) of a collocation. The high relevance of the research is due to the need to understand idiomatization in the light of both corpus linguistics and language philosophy. The purpose of the study is to define the role played by the development of a collocation in the process of idiomatization. To solve this problem, a diachronistic approach was used during the research. The accumulation of reproducibility changes over the collocation history was interpreted as development. The process of collocation idiomatization was considered as a qualitative-quantitative transition: the degree of development of the collocation (the result of quantitative changes) can become the basis for its transition to an idiom (qualitative change). The paper is intended for specialists in the field of diachronic phraseology of the German language, general linguistics, corpus linguistics, and philosophy of language.

Abstract Background Previous research has illustrated a relationship between emotion dysregulation and suicidal ideation, both cross-sectionally and longitudinally. However, it is not yet understood how this relationship manifests. The aim of this study was to explore if two beliefs about suicide, (1) suicide as a way to escape from emotional pain and (2) suicide as a solution to a problem, moderate the relationship between emotion dysregulation and suicidal ideation. Methods One hundred one community participants completed questionnaires examining emotion dysregulation, suicidal ideation, and beliefs in the functions of suicide. Inclusion criteria were used to over-sample individuals within the community experiencing higher levels of suicidal ideation and emotion dysregulation. Hierarchical linear regressions with interaction terms were used to assess moderation effects. The moderating role of beliefs in the function of suicide was examined both cross-sectionally and longitudinally. Results Suicide as an escape significantly moderated the relationship between global emotion dysregulation and suicidal ideation cross-sectionally, while it moderated the relationship between a facet of emotion dysregulation and suicidal ideation longitudinally. Greater endorsement of this belief resulted in a stronger relationship between emotion dysregulation and suicidal ideation. The function of suicide as a solution to a problem did not moderate the emotion dysregulation-suicidal ideation relationship. Conclusions These findings underscore the importance of not only addressing emotion dysregulation but also addressing the underlying belief that suicide is an escape in individuals who experience both emotion dysregulation and suicidal ideation. Intervention efforts to address belief in suicide as an escape along with emotion dysregulation are delineated.
