The author discusses the importance of studying socio-structural factors of socio-economic development through a broader application of the economic approach. The resources of status positions of economic agents are in the spotlight. A possible platform for interdisciplinary interactions is proposed which allows to increase the contribution of both economics and sociology in improving governance at all levels.

Mechanism of catalysis with binary and triple catalytic systems based on redox inactive metal (lithium) compound {LiSt+L2} and {LiSt+L2+PhOH} (L2=DMF or HMPA), in the selective ethylbenzene oxidation by dioxygen into -phenylethyl hydroperoxide is researched. The results are compared with catalysis by nickel-lithium triple system {NiII(acac)2+LiSt+PhOH} in selective ethylbenzene oxidation to PEH. The role of H-bonding in mechanism of catalysis is discussed. The possibility of the stable supramolecular nanostructures formation on the basis of triple systems, {LiSt+L2+PhOH}, due to intermolecular H-bonds, is researched with the AFM method.

This study aims to determine the role of the Ombudsman of the Republic of Indonesia in North Sumatra Representative in the Supervision of Population and Civil Registry Service in Medan City. This study uses a qualitative approach with descriptive methods describing information about the data obtained from the field in the form of written and oral data from the parties studied. Data is collected based on interviews and documentation. The results of this study indicate that the role of the Ombudsman of the Republic of Indonesia in North Sumatra was carried out in the form of external supervision. External supervision is supervision carried out by the Ombudsman of the Republic of Indonesia Representative of North Sumatra to the Medan Population and Civil Registry Service. Actions taken in the supervision process are incoming reports, follow-up of the first report and follow-up of the report. Based on the research that has been carried out, it has been concluded that the role of the Ombudsman of the Republic of Indonesia in the North Sumatra Representative in supervising the service provider of the Population and Civil Registry services is carried out in the form of external supervision. In supervising the handling of public reports of alleged poor service in the area of population administration, it has been effective, with several efforts to handle reports such as: (1) Clarification; (2) Investigation; (3) Recommendations; (4) Monitoring.

AbstractCeO2, V2O5 and CeVO4 were synthesised as bulk oxides, or deposited over activated carbon, characterized by XRD, HRTEM, CO2-TPO, C3H8-TPR, DRIFTS and Raman techniques and tested in propane oxidative dehydrogenation using CO2. Complete oxidation of propane to CO and CO2 is favoured by lattice oxygen of CeO2. The temperature programmed experiments show the ~ 4 nm AC supported CeO2 crystallites become more susceptible to reduction by propane, but less prone to re-oxidation with CO2 compared to bulk CeO2. Catalytic activity of CeVO4/AC catalysts requires a 1–2 nm amorphous CeVO4 layer. During reaction, the amorphous CeVO4 layer crystallises and several atomic layers of carbon cover the CeVO4 surface, resulting in deactivation. During reaction, V2O5 is irreversibly reduced to V2O3. The lattice oxygen in bulk V2O5 favours catalytic activity and propene selectivity. Bulk V2O3 promotes only propane cracking with no propene selectivity. In VOx/AC materials, vanadium carbide is the catalytically active phase. Propane dehydrogenation over VC proceeds via chemisorbed oxygen species originating from the dissociated CO2.

Abstract Background The COVID-19 pandemic has uncovered the ways in which disabled people are made more vulnerable due to structural inequalities. These vulnerabilities are the result of the interaction between individual and structural factors that shape how risk is experienced by disabled people. In Australia, these vulnerabilities are influenced by the way disability services and care for disabled people are delivered through a consumer-directed approach. We analysed the policies and documentation made by the Australian Government and state and territory governments during the pandemic to explore whether these were disability-inclusive. We aimed to unpack how these policies shaped disabled people as vulnerable citizens. Methods Guided by documentary research, we used framework analysis to examine the policies of the Australian Government and state and territory governments. We analysed legislation that was given royal assent by the federal, state and territory governments, and documents (reports, fact sheets, guidance documents, etc.) published by the federal government and the state of Victoria (given that this state experienced the brunt of the epidemic in Australia) between February 2020 to August of 2020. Results We found that most of the resources were not aimed at disabled people, but at carers and workers within disability services. In addition, most policies formulated by the Australian Government were related to the expansion of welfare services and the creation of economic stimulus schemes. However, while the stimulus included unemployed people, the expansion of benefits explicitly excluded disabled people who were not employed. Most of the legislation and documents offered accessibility options, though most of these options were only available in English. Disability oriented agencies offered more extensive accessibility options. Conclusions The findings indicate a large number of documents addressing the needs of disabled people. However, disability-inclusiveness appeared to be inconsistent and not fully considered, leaving disabled people exposed to greater risk of COVID-19. Neoliberal policies in the health and welfare sector in Australia have led to an individualisation of the responsibility to remain healthy and a reliance on people as independent consumers. Governments need to take a clear stance towards the emergence of such a discourse that actively disvalues disabled people.
