The purpose of the work. Elucidation of changes in the number and distribution of little bustard (Tetrax tetrax Linnaeus, 1758) on the territory of the Rostov Nature Reserve in the 20th-21st centuries and the reasons for their transformation. Place and methods of work. The reserve is located in the arid Eastern European steppes. The authors used their own observations from 1959 and publications on Tetrax tetrax L. The materials are collected using regular route methods and animal tracking at individual sites, as well as analysis of published information. Results. The little bustard is a characteristic steppe species that historically lived on the Don land. Since the mid-twentieth century, the steppes have experienced deep anthropogenic changes, which have had a great impact on this species. Currently, the little bustard in the steppe zone is a rare species. The creation of the reserve has had a positive impact on this species. In it, the little bustard is a small breeding species, and its number is constrained by a number of factors. The intensification of economic activity in the region and the aridization of the climate make it necessary to improve environmental protection work.

The Creation

The complex of mammals on the territory of the Rostov Nature Reserve located in the arid steppes in the 20th-21st centuries was studied and the reasons for the changes that occurred in it were determined. We used the authors' observations since 1959, data from the staff of the Rostov Nature Reserve and publications on mammals. A total of 46 species of mammals were recorded. Under the influence of human activity steppe ecosystems underwent profound transformations, which led to changes in the number, distribution and importance of many mammals and to the disappearance of some and the penetration of other species here. The creation of the Rostov Nature Reserve has had a positive impact on the restoration of biocenoses. However, their composition differs from that of the mid-twentieth century. In the 21st century steppe ecosystems, including mammals, are affected by increased economic activity and climate change.

Payment Instruments

Payments are an inherent element of economic activity (León and Ortega 2018). However, the evolution of payment instruments and the way individuals and businesses make daily payments has undergone enormous change in human history, particularly due to main innovations in payment systems in last decades (Gandhi 2016). The last innovation in payment system concerns mobile payment. The development of mobile payments market can have a positive impact on economic growth (Leon and Rodriguez 2012). Although the Polish market of mobile payments is in the initial phase of development, it is one of the pioneering and leading in Europe and globally. The main purpose of this article is to analyze, which feature (convenience, speed, availability, ease of use, safety) of mobile payments could be the most important for users from Poland.

AbstractOver the last decade, the EU’s fundamental values have been under threat at the national level, in particular among several Central and Eastern European states that joined the EU since 2004. During this time, the European People’s Party (EPP) has been criticized for its unwillingness to vote for measures that would sanction the Hungarian Fidesz government, one of its members, in breach of key democratic principles since 2010. In this paper, we seek to understand how cohesive the EPP group has been on fundamental values-related votes, how the position of EPP MEPs on these issues has evolved over time, and what explains intra-EPP disagreement on whether to accommodate fundamental values violators within the EU. To address these questions, we analyse the votes of EPP MEPs across 24 resolutions on the protection of EU fundamental values between 2011 and 2019. Our findings reveal below-average EPP cohesion on these votes, and a sharp increase in the tendency of EPP MEPs to support these resolutions over time. A number of factors explain the disagreements we find. While the EPP’s desire to maintain Fidesz within its ranks is central, this explanation does not offer a comprehensive account of the group’s accommodative behaviour. In particular, we find that ideological factors as well as the strategic interests of national governments at the EU level are central to understanding the positions of EPP MEPs, as well as the evolution of these positions over time. These results further our understanding of the nature of the obstacles to EU sanctions in fundamental values abuse cases, and the role of partisanship in fuelling EU inaction especially.

The study of the nature reserve oak forest near the village of Pelya-Khovanskaya ecosystem was done in the region of Nizhny Novgorod. The investigated wood is unique for its complex structure. It is situated in the forest-steppe zone, characterized by a high species diversity of small mammals and vegetation, which indicates the complexity of trophic and spatial connections. Several series of sample plots were described: 41 of 2020 m and a number of 11 m sites, totaling 300. Abundance of species by Brown-Blanke scale and the number of specimens of adolescence were specified for each 1 sq. m. plot. Mammals were trapped with the help of trapping grooves and transects method. Vegetation cover is characterized by the presence of a clear intra-differentiation as well as the existence of two basic ecologo-coenotic groups/cores - the nemoral (with Pulmonaria obscura Dum. as the center species of the core) and the meadow-fringe. The most distinct group is formed by forest-shoot species. It can be explained by more forest-steppe rather than nemoral nature of vegetation. Small mammals are represented by the following species: common and small shrews, small forest mouse, yellow-throated and field mice and harvest mouse, vole-housekeeper, common, plowed and red voles, European mole. Two species among them - vole-housekeeper and mouse-baby - are listed in the Red Book of the Nizhny Novgorod Region. Matching burrows of mouse-like rodents with soil richness with nitrogen and humidity, two well-defined peaks are observed. The greatest number of burrows is found in places where the soil is high in nitrogen. Moles were found in areas with a large projective coating of Primula veris: coefficient Spearman rank 0,50. There was a negative correlation of the number of moles and vegetation covering of Pyrethrum corymbosum (-0,46), which is the marker of the driest parts in the forest. In general, the nature reserve oak forest near the village of Pelya-Khovanskaya is of considerable interest, both from botanical and from zoological point of view. Long-term studies of biocoenosis will allow to monitor the facility and to correct the proposed protective measures.

Abstract Since reserve requirement is the only monetary policy instrument used in Montenegro, it has been subject to frequent amendments since the global crisis outbreak. The analysis of the monetary demand model showed that there is an active transmission mechanism of change in the reserve requirement rate on the deposits trend reflects on lending activity. Also, there is a significant impact of FDIs on deposits trending in the banking system, as well as the positive impact of turnover on stock exchange on the deposits and loans trend. Finally, it was found that the financial crisis has caused negative trends in loans and deposits. On the other hand, the impact of changes in the reserve requirement on the economic activity in Montenegro could not be determined. This is primarily due to the fact that the transmission mechanism of the effect of reserve requirement on economic activity is too long to be able to estimate the model that does not allow the dynamics of the independent variables. The second reason is that industrial output index is only an indirect indicator of the economic activity.

Transportation is the backbone in creating social welfare in Jakarta. Therefore, if there are problems in the transportation system, it will have an impact on the smooth traffic flow and will ultimately hamper the achievement of public welfare. This study used a descriptive-qualitative method. This study refers to the theory proposed by Anderson (in Tachjan, 2006: 23) and Sarana, et al (2009: 9). The results of the study are as follows. Policy implementation transportation system in Jakarta has been able to improve the social welfare of most citizens, which means some people have to feel and enjoy the outcome of transportation development  in Jakarta. However, others have not optimally felt the positive impact of the policy. Even, it is perceived negatively; such as traffic jams which are almost evenly distributed throughout Jakarta causing high air pollution, hampered economic activity and generated high economic costs that social welfare was also weakened. This is reinforced by the increasing poverty rate in 2014 that reached 393,980 people thousand compared to previous years.

Use Of Social Media

Use of social media creates positive or negative impacts on adolescents. There are a number of factors enabling adolescents to make use of social media positively. One of the factors studied in this research is the adolescent worldview. The adolescent worldview greatly determines the way she behaves and her attitude towards social media. The result of this research shows that adolescent worldview may release and enables her to reject negative impacts of social media, particularly from modern cultural -isms as relativism, individualism, emotionalism, presentism (present-time ism), materialism, autonomy, victimism, and turn it into a positive impact on herself. Worldviews may be differentiated based on three categories namely religion, spirituality and secularity. This research is conducted by explorative-qualitative approach, using case study research method. Data collection was conducted by in-depth interview with late adolescents.

The Impact

Generational differences present a new aspect of diversity among employees in the workplace. The increasing number of older employees and negative attitudes of younger employees toward them create the need for better understanding between generations and the need to improve mutual cooperation among age-diverse employees in an organisation. The main objective of the paper is to determine the impact of intergenerational synergy on the work engagement of older employees in Slovenia. For this purpose, empirical research was conducted in medium-sized and large companies among employers and older employees in Slovenia. Factor analysis was used to replace a large number of statements with a smaller number of factors - new variables with which we performed a simple linear regression. Based on the results, we confirmed the hypothesis that promoting intergenerational synergy in companies has a statistically significant positive impact on the work engagement of older employees in Slovenia. In this context, companies should take the following measures: eliminate discrimination of older employees, promote intergenerational synergy, and promote intergenerational understanding between young and older employees.
