Formation of metallic magnetic clusters in a Kondo-lattice metal: Evidence from an optical study

Magnetic materials are usually divided into two classes: those with localised magnetic moments, and those with itinerant charge carriers. We present a comprehensive experimental (spectroscopic ellipsomerty) and theoretical study to demonstrate that these two types of magnetism do not only coexist but complement each other in the Kondo-lattice metal, Tb2PdSi3. In this material the itinerant charge carriers interact with large localised magnetic moments of Tb(4f) states, forming complex magnetic lattices at low temperatures, which we associate with self-organisation of magnetic clusters. The formation of magnetic clusters results in low-energy optical spectral weight shifts, which correspond to opening of the pseudogap in the conduction band of the itinerant charge carriers and development of the low- and high-spin intersite electronic transitions. This phenomenon, driven by self-trapping of electrons by magnetic fluctuations, could be common in correlated metals, including besides Kondo-lattice metals, Fe-based and cuprate superconductors.Comment: 30 pages, 6 Figure

Common Health: The Role of Non-Profit Organizations in Supporting Community Action for Health Equity and Justice

This dissertation explores the ways in which reporting requirements, evaluations, management decisions and other metrics and processes contribute to a growing gap between community development goals of community health centres and their practice. My argument is that there is a gap between the community development mandate of non-profit organizations and their practices, which is increasingly shaped toward direct service-delivery and steered away from the advocacy and community development pillars of their mandates. As a result, the capacity of non-profit organizations to support equitable community participation is curbed. Such a gap is largely facilitated through funding relations that prioritise functional accountability and results-based performance measurement that are consistent with extractivist capitalism. Extractivist goals of neoliberal capitalism imposed on non-profits undermine the goals of equity and social justice in urban community development. The purpose of this research is a careful examination and explication of power relations in everyday work of practitioners in the non-profit sector. I examine non-profit organizations as civil society actors, situated in the broader context of neoliberal capitalism where some actors are subordinate to others, and where subordination results from unequal access to and distribution of resources. I employ institutional ethnography and participatory action research as a methodology. I collected data from two community health centres and one inter-organizational network located in Torontos priority neighbourhoods and interviewed community volunteers, frontline workers, management staff and funders. I also reviewed documents such as reporting requirements and templates, evaluation frameworks and reports. In order to capture the ways in which reporting and functional accountability systems normalize extractivist processes in the non-profit sector, I constructed maps and diagrams to make such processes explicit. My research analyses how the role of non-profit organizations in regard to community action is shaped within capitalist power relations. To counteract and resists extractivist processes, I propose directions for strengthening the role of non-profit organizations as partners in collaborative processes involving co-production with community members

Features of insurance risks’ classification as the basis of risk management of insurance companies in the financial crisis

Since the global financial crisis had impacted on all aspects of insurance companies' activities, it became necessary to focus on the activities of insurers and further improve the integrated risk and capital management of global and regional insurers. The purpose of the research is to analyze differences between national and European standards for risk identification in Ukrainian insurance companies, and to provide suggestions for improving the mechanism of risk insurance management. Using the method of comparative analysis and the method of content analysis of national and international solvency standards for insurance companies, the national characteristics of the types of insurance risks and the organization of the implementation of European legislation in domestic practice were determined. By the method of generalization and deduction, the key challenges for improving the effectiveness of insurance risk management in Ukrainian practice were identified. The results of the study shows the necessity to implement a unified system of insurance risk management in Ukrainian practice, which contents national and global characteristics of the functioning of insurance markets. The results of the research have significant practical implications for insurance companies and state government insurance market and can serve as a basis for improvement of theoretical principles concerning the identification of insurance risks and implementing European experience of insurance companies in national practice

Experimental determination of the boundaries of the influence of a stope working on the earth's surface

The theoretical part of the research methodology is developed according to the scheme of subsidence of points on the earth's surface relative to the projection of the face. The curve of the trajectory of the subsidence of the earth's surface is divided by characteristic points at different stages of subsidence of the earth's surface. Such stages include: the beginning of the displacement of the earth's surface, the active stage of displacement, the end of the active stage and the attenuation of the processes of subsidence of the earth's surface. According to the goal and the design scheme, on the basis of experimental data, we determined the parameters corresponding to the location of a point on the earth's surface where it began to settle. In relation to the scheme under consideration, three well-known dependencies were analyzed to describe the subsidence curve of the earth's surface: the exponential equation, the hyperbolic tangent function, and the logistic curve. Based on them, it was established that the main influencing factor determining the boundary of the dynamic half-mold is the depth of mining operations, and the boundary angles are practically independent of this parameter

Water Conflicts in Central Asia: Some Recommendations on the Non-Conflictual Use of Water

Central Asian states, where freshwater is a strategic resource, are oriented towards regional conflict rather than cooperation. First, the article analyses the role of the unequal distribution of freshwater that has been generating conflicts in Central Asia in the post-Soviet period. Next, these conflicts are examined. Finally, we provide some recommendations on the non-conflictual use of water
