Why can some countries perform better in resolving some social problems:A comparative study

引用

Economic and Political Studies 2024年第3期12卷 250-266页

作者： Wilson X.b.Li tina t.He Faculty of business and Management BNU-HKBU United International CollegeZhuhaiChina

this study explores the rationale why some countries fare better in resolving social problems such as poverty and the cOVID-19 *** simple model introduces the term of resident viability and points out that the solution to a social problem with a large ratio of nonviable to viable residents requires the mobilisation of more societal resources,and the affordable price ratio of societal to individual resources is determined by country characteristics such as the cultural background,political regime,ideology towards the free-market mechanism,government efficiency and social *** study also makes between-country comparisons and conducts preliminary regression analyses with cross-country data,and all the results are consistent with the model predictions on the relationship between country characteristics and country performances in fighting poverty and handling the cOVID-19 pandemic.

the thermoluminescence(tL)emission of synthetic and natural ce-monazites was characterized here to determine the potential application in the identification of microscopic defects from a qualitative point of view trying to link each tL peak to a chemical-physical *** kinetic parameters that lead the luminescence processes were calculated by means of variable heating rate and computing glow curve deconvolution methods and allow identifying three groups of components at~90,130 and 290℃(for the mineral sample)and~90,170,220,270 and 320℃(for the synthetic cePO_(4):Nd_(0.20),La_(0.25)).the main differences appreciated in these complex tL curves are mainly due to(i)the content of impurities(natural sample contains lanthanides as well as U 0.60%and th 5.22%)and(ii)the degree of crystallinity of the samples which is directly related to the type of impurities(synthetic monazite relies only on Nd and La).the behavior of the dose response in the range of 1-8 Gy is similar for both samples;the tL intensity increases linearly as the dose increases without changes in the position of the maxima,denoting first-order kinetic luminescence *** peak could be mostly associated with structural defects(i.e.,phase transitions),chemical reactions(i.e.,ce3+?ce4+redox reaction,dehydration or dehydroxylation processes)or intrinsic defects(i.e.,Frenkel defects,ODcs or NbOHcs).
