The Impact

Ecosystem services (ES), as an interconnection of the landscape mosaic pieces, along with temporal rivers (IRES) are an object of research for environmental planners and ecological economists, among other specialists. This study presents (i) a review on the importance of IRES and the services they can provide to agricultural landscapes; (ii) a classification tool to assess the impact of IRES to provide ES by agricultural landscapes; (iii) the application of the proposed classification to the Caia River in order to identify the importance of this intermittent river for its surrounding agricultural landscape. The classification of the ES follows the Common International Classification of Ecosystem (CICES) classification that was adapted for the purposes of this study. Firstly, the list of ES provided by agricultural landscape was elaborated. In the next step, we assessed the potential of IRES to provide ES. Next, IRES impacts to ES within the agricultural landscape were evaluated according to observations from the conducted field monitoring in the study area. This study focuses on the relevance of the intermittent Caia River—a transboundary river in Spain and Portugal—and its ephemeral tributaries in the agricultural landscape. Our study estimates that each hydrological phase of IRES increases the ES provided by the agricultural landscape. However, the dry phase can potentially have negative impacts on several services. The intensification of the agricultural sector is the main provision of the water resource within the Caia River basin, but we were able to identify several other ES that were positively impacted. The present study is in line with the conclusions of other authors who state that IRES constitute a valuable resource which should not be underestimated by society.

The Impact

The Tagueleft basin is geographically located in the northern edges of the Middle High Atlas, which is a geomorphological fragile area. The impact of human activity has accelerated water erosion in this mountains area. This is reflected in dynamic and unstable foothills, a decrease in forests density and degradation in the production of the land. On the other hand, land degradation due to human overexploitation of natural resources has increased land degradation in the area. The interest in the risk of erosion on the foothills in the area under study comes in the context of our contribution to clarify the role of geomatical and geomorphological approaches in explaining and identifying the mechanisms responsible for current foothills dynamism through water erosion and its negative impacts on the environment and local development. The aim of the study was to use the EPM (Erosion Potential Méthod) which is formulated by Slobodan Gavrilovic for erosion in mountainous areas and to test the reliability of its results based on fieldwork and remote sensing data. The results of the erosion assessment and its quantification by applying the coefficient (W) for the theoretical model in the area under study have shown that erosion is very important and it touches on wide areas as it appears through the domain classification of the distribution erosion in Tagueleft basin.

The current study was heading for determining the impact of Pakistani university students’ socioeconomic classes on their personality traits. Demographic and personality questionnaires were filled by available university students online. The stepwise regression technique facilitated to generate regression models to define impacts of different socioeconomic classes on students’ different personality traits. Different regression models highlighted the significant negative impacts of the middle upper socioeconomic class on Agreeableness, Extraversion and Neuroticism personality traits. The lower socioeconomic class was found to have positive impact on only one personality sub-trait self-discipline. Whereas, the upper lower socioeconomic class caused positive impacts on students’ trust sub-trait, Conscientiousness trait and negative impact on excitement seeking sub-trait of personality. The importance of these impacts of socioeconomic classes on different personality traits and the possible implications are discussed with respect to university students’ academic performance and academic behaviour.

The Impact

Bracing is the most common non-operative treatment option for patients with adolescent idiopathic scoliosis (AIS). However, existing brace designs have deficiencies, including a long production lead time and low patient compliance caused by the negative impacts of bracing on quality of life (QoL). The aim of this study was to address these problems by developing a new textile-based scoliosis brace in accordance with the biomechanics used in the existing braces for spinal correction. A case study of interface pressure had been carried out to determine the optimum combination of pads to be used in the proposed brace to correct a scoliotic spine. AIS patients who were undergoing hard brace treatment were recruited to complete a questionnaire (BrQ) on hard braces and on the proposed brace. The BrQ scores of the two types of braces were compared to assess their respective impacts on the QoL. The findings show that the proposed brace can address the issue of patient compliance by reducing the impact of bracing on QoL, and shorten the production lead time through incorporation of the mass customization concept into the design. Similar to most of the commonly-used scoliosis braces, the selected combination of pads used in the proposed brace for spinal correction shows a sufficient amount of exerted pressure and a similar function of active spinal correction.

Abstract Non-forest tree stands are important habitats for many species of birds in the agricultural landscape. They are also the main habitat of the Syrian Woodpecker Dendrocopos syriacus, whose numbers have been decreasing in recent years in some parts of Europe. Recognition of the habitat requirements of this species may help better planning of its protection in the context of the treed agricultural landscapes. During this study, the habitat preferences of the Syrian Woodpecker were determined in the agricultural landscape of South-Eastern Poland. A set of 12 habitat parameters of tree stands located in the breeding territories of the Syrian Woodpecker (n = 122) and in randomly chosen control areas (n = 122) located outside the range of the breeding territories of this species were characterized. The number and species diversity of trees was significantly higher in stands located in Syrian Woodpecker territories than in the random control areas. Stands occupied by breeding pairs also had trees of worse health condition and a larger proportion of fruit trees. The model best explaining the probability of the occurrence of the species indicates that the Syrian Woodpecker requires mainly the presence of tree stands with a greater species diversity of trees, as well as tree stands in worse health condition. When planning the protection of this species’ habitats in the agricultural landscape, the characteristics of non-forest tree stands noted above should be taken into account.

Тhe problems of valuation of ecosystem services in connection with the activation of economic activity of the Russian Federation in the Arctic zone are discussed. The types of negative impacts on the Arctic ecosystems and their assessment, investment risks existing in ecosystem services are considered. It is shown that the application of the methodology and apparatus of ecosystem services contributes to the adequate assessment and creation of a hierarchical classification of "usefulness" and "benefits" that society can get from the existence, use and nonuse of ecosystems. The concept of ecosystem services in relation to Arctic consists of three components: identification, monetization and ecological risk assessment. The example of the Arctic ecosystems shows that the susceptibility to assessment and the accuracy of the assessment can be quite different and is largely dependent on the type of service in the classification. The analysis of possible ecosystem services and their relationship with the quality of life of people in the Russian Arctic indicates significant investment risks.

The Impact

A comprehensive diachronic analysis (1951–2010) of precipitation and temperature regimes has been carried out at the national and regional scale in Italy to investigate the impact of climate aridity on the agricultural system. Trends in climate aridity have been also analysed using UNEP aridity index which is the ratio between rainfall and potential evapotranspiration on a yearly basis. During the examined time period, and particularly in the most recent years, a gradual reduction in rainfall and growing temperatures have been observed which have further widened the gap between precipitation amounts and water demand in agriculture.

Ecosystem services are the benefit human populations derive directly and indirectly from the natural environment. They suffer from both the human intervention, like land use zoning change, and natural intervention, like the climate change. Under the background of climate change, regulation services of ecosystem could be strengthened under proper land use zoning policy to mitigate the climate change. In this paper, a case study was conducted in the middle reaches of the Heihe River Basin to assess the ecosystem services conservation zoning under the change of land use associated with climate variations. The research results show the spatial impact of land use zoning on ecosystem services in the study area which are significant reference for the spatial optimization of land use zoning in preserving the key ecosystem services to mitigate the climate change. The research contributes to the growing literature in finely characterizing the ecosystem services zones altered by land use change to alleviate the impact of climate change, as there is no such systematic ecosystem zoning method before.

Translational Models

The article discusses the conventional models and translation techniques, which are most common among the Polish translators of the weird fiction by Howard Phillips Lovecraft. The proposed classification of such models, aimed at either “popularisation,” “stereotypisation” or “revision” of Lovecraft’s short stories, presents the impact of extra-textual factors (vision of the writer, target group of readers, cultural and political influences) on the content, language and style of translated works by the American author. The comparative analysis takes into consideration one of the early short stories by Lovecraft, “Dagon” (1917), and its Polish versions by Arnold Mostowicz (1973), Robert Lipski (1994) and Maciej Płaza (2012).
