The province of Macerata, Italy, is a topographically complex region which has been little studied in terms of its temperature and precipitation climatology. Temperature data from 81 weather stations and precipitation data from 55 rain gauges were obtained, and, following quality control procedures, were investigated on the basis of 3 standard periods: 1931–1960, 1961–1990 and 1991–2014. Spatial and temporal variations in precipitation and temperature were analysed on the basis of six topographic variable (altitude, distance from the sea, latitude, distance from the closest river, aspect, and distance from the crest line). Of these, the relationship with altitude showed the strongest correlation. Use of GIS software allowed investigation of the most accurate way to present interpolations of these data and assessment of the differences between the 3 investigated periods. The results of the analyses permit a thorough evaluation of climate change spatially over the last 60 years. Generally, the amount of precipitation is diminished while the temperature is increased across the whole study area, but with significant variations within it. Temperature increased by 2 to 3 °C in the central part of the study area, while near the coast and in the mountains the change is between about 0 and 1 °C, with small decreases focused in the Appennine and foothill belt (−1 to 0 °C). For precipitation, the decrease is fairly uniform across the study area (between about 0–200 mm), but with some isolated areas of strong increase (200–300 mm) and only few parts of territory in which there is an increase of 0–200 mm, mainly in the southern part of the coast, to the south-west and inland immediately behind the coast. The monthly temperature trend is characterized by a constant growth, while for precipitation there is a strong decrease in the amount measured in January, February and October (between 25 and 35 mm on average).

Extreme precipitation trends and events are fundamental for the definition of the region’s climate and allow the subsequent analysis of the risk for the territory and the possible countermeasures. This study takes into account the Marche Region (Central Italy) with 128 rain gauges from 1921 to 2017. Initially, in order to obtain a rainfall overview, the dominant trend of the period 1921–2017 was evaluated. Initially, in order to obtain a rainfall overview, the dominant trend of the period 1921–2017 was evaluated. In addition, to obtain a comparable analysis, the average precipitations grouped in climatological standard normals were analyzed. Finally, the main purpose of the research was achieved by analyzing extreme events in the middle Adriatic side. In addition, forecasts of extreme precipitation events, with a return period of 100 years, were made using the theory of “generalized extreme value” (GEV). The innovation of this research is represented by the use of geostatistics to spatialize the variables investigated, through a clear and immediate graphic representation performed through GIS software. This study is a necessary starting point for the study of climate dynamics in the region, and it is also a useful tool for land use planning.

AbstractUnderstanding the dynamics and distribution of CO2 in the subsurface atmosphere of carbonate karst massifs provides important insights into dissolution and precipitation processes, the role of karst systems in the global carbon cycle, and the use of speleothems for paleoclimate reconstructions. We discuss long-term microclimatic observations in a passage of Postojna Cave, Slovenia, focusing on high spatial and temporal variations of pCO2. We show (1) that the airflow through the massif is determined by the combined action of the chimney effect and external winds and (2) that the relationship between the direction of the airflow, the geometry of the airflow pathways, and the position of the observation point explains the observed variations of pCO2. Namely, in the terminal chamber of the passage, the pCO2 is low and uniform during updraft, when outside air flows to the site through a system of large open galleries. When the airflow reverses direction to downdraft, the chamber is fed by inlets with diverse flow rates and pCO2, which enter via small conduits and fractures embedded in a CO2-rich vadose zone. If the spatial distribution of inlets and outlets produces minimal mixing between low and high pCO2 inflows, high and persistent gradients in pCO2 are formed. Such is the case in the chamber, where vertical gradients of up to 1000 ppm/m are observed during downdraft. The results presented in this work provide new insights into the dynamics and composition of the subsurface atmosphere and demonstrate the importance of long-term and spatially distributed observations.

Abstract:This article focuses on the mechanisation of agriculture in central Italy in the thirty years or so after 1945. This provides a particular way of examining the major changes in the rural landscape in this period, especially the end of the sharecropping system. Land in these regions had for centuries been predominantly farmed under sharecropping contracts, but for political, economic, and demographic reasons this system, which had inhibited modernisation, entered a rapid decline. Whereas labour supply had previously exceeded demand, the reverse became the case, allowing sharecropping families more freedom in how they operated. Mechanisation was not a ‘push’ factor, but as the agricultural labour force contracted it was a necessary response. The article uses individual testimony to illustrate how tenant farmers started to work outside the sharecropping contract, some becoming outside contractors with other farms and supplying tractor hire. The mechanisation of agriculture was slow and uneven, but marked an irreversible change in the relationship between farming families and their land.

The present study suggests a method of integrating user performance and attitudes toward the computer system into the quality control procedures (QCP). The objective of this approach is to enable the decision makers to manage by exceptions (MBE) and thus be more effective and more efficient. Accordingly, this study computes the correlations between performance related variables and users' attitudes. The computer facility management will investigate only systems whose users have demonstrated performance or attitudes below a desirable minimum level and thus manage by exception. Likewise, the relationship between performance and attitude will be investigated.

Dengue, a reemerging disease, is one of the most important viral diseases transmitted by mosquitoes. Climate is considered an important factor in the temporal and spatial distribution of vector-transmitted diseases. This study examined the effect of seasonal factors and the relationship between climatic variables and dengue risk in the city of Rio de Janeiro, Brazil, from 2001 to 2009. Generalized linear models were used, with Poisson and negative binomial distributions. The best fitted model was the one with "minimum temperature" and "precipitation", both lagged by one month, controlled for "year". In that model, a 1°C increase in a month's minimum temperature led to a 45% increase in dengue cases in the following month, while a 10-millimeter rise in precipitation led to a 6% increase in dengue cases in the following month. Dengue transmission involves many factors: although still not fully understood, climate is a critical factor, since it facilitates analysis of the risk of epidemics.

Herbaria contain a cumulative sample of the world's flora, assembled by thousands of people over centuries. To capitalize on this resource, we conducted a specimen-based analysis of a major clade in the grass tribe Andropogoneae, including the dominant species of the world's grasslands in the genera Andropogon , Schizachyrium , Hyparrhenia and several others. We imaged 186 of the 250 named species of the clade, georeferenced the specimens and extracted climatic variables for each. Using semi- and fully automated image analysis techniques, we extracted spikelet morphological characters and correlated these with environmental variables. We generated chloroplast genome sequences to correct for phylogenetic covariance and here present a new phylogeny for 81 of the species. We confirm and extend earlier studies to show that Andropogon and Schizachyrium are not monophyletic. In addition, we find all morphological and ecological characters are homoplasious but variable among clades. For example, sessile spikelet length is positively correlated with awn length when all accessions are considered, but when separated by clade, the relationship is positive for three sub-clades and negative for three others. Climate variables showed no correlation with morphological variation in the spikelet pair; only very weak effects of temperature and precipitation were detected on macrohair density. This article is part of the theme issue ‘Biological collections for understanding biodiversity in the Anthropocene'.

Abstract. Interannual variations of catchment streamflow represent an integrated response to anomalies in regional moisture transport and atmospheric circulations, ultimately linked to large-scale climate oscillations. This study investigates the relationship between Taiwan's long-term summertime (July to September, JAS) streamflow and manifold teleconnection patterns. Lagged correlation analysis is conducted to calculate how JAS streamflow data derived at 28 upstream and 13 downstream gauges in Taiwan correlate with 14 teleconnection indices in the concurrent or preceding seasons. Out of the many indices, the West-Pacific and Pacific-Japan (PJ) patterns, both of which play a critical role in determining cyclonic activity in the western North Pacific basin, exhibit the highest concurrent correlations (most significant r = 0.48) with the JAS flows in Taiwan. At a one-month lead time, on the other hand, the Quasi-Biennial Oscillation significantly correlate with the JAS flows (most significant r = −0.66), indicating some forecasting utility. By further examining the correlation results using a 20-year moving window, peculiar temporal variations and possible climate regime shifts (CRS) can be revealed. To identify suspicious, abrupt changes in the correlation, a CRS test is employed. The late 1970s and 1990s are identified as two significant change points, and during the intermediate period, a marked in-phase relationship (r ~ 0.9) between Taiwan's streamflow and the PJ index is observed. It is verified that the two shifts are in concordance with the alteration of large-scale circulations in the Pacific basin. Discussion about the changes in pattern correlation and composite maps before and after the change point is carried out, and our results suggest that empirical forecasting techniques should take into account the effect of CRS on predictor screening.

The implementation of customs control occupies a significant share of the activities of customs officers. Customs control procedures make it possible to identify customs violations in a timely manner, to ensure the content of measures aimed at preventing customs offenses, reveals the possibility of identifying shortcomings in the work of customs officials who are responsible for a particular area of work. In addition, the customs control procedure reveals not only the shortcomings in the work of certain parts of the customs, but above all, establishes the level of compliance with the principles of customs control and performance of its functions. This thesis is based on the fact that in case of violation of these segments there is a certain area of activity, which usually acts as a zone of customs violations. At the same time, customs control helps to improve the quality of document flow and provides an opportunity to form more realistic information flows for management decisions. At the same time, customs control procedures provide an opportunity to determine the relationship between the elements of the organizational mechanism, to establish at what stage is the duplication of functional responsibilities of responsible persons, and on this basis to decide on its improvement in the future. However, these advantages of customs control are partially offset by a number of negative factors that have some impact on the effectiveness of the procedure itself. There are professional and scientific discussions about the content of negative factors influencing customs control procedures, among which the leading role is given to the shortcomings in the law-making process. Existing problems indicate the feasibility of conducting research in this area. The article highlights the existing problematic factors influencing the customs control procedures, reveals the legal regulations for their implementation and determines the content of the principles and functions that customs officers are obliged to adapt during their adaptation. Attention is paid to the expediency of expanding the functions of the customs control procedure, the advantage of such changes is outlined. The author's position of content of conceptual categories «customs control», «customs control procedure», «organization of customs control» with the substantiation of the chosen approach is offered. The specific features of the organization of the customs control procedure are revealed, the main tasks are determined and the directions of its improvement are established. The author's position on the expediency of choosing both legal and human factors in the development of measures to improve the customs control procedure is given. The relationship between the qualification level of the executors of control actions and the effectiveness of the customs control procedure is substantiated.
