Restabilization Process in Matching Markets with Workers Proposing

Open Journal of Discrete Mathematics 2022年第4期12卷 101-112页

作者： millán beatriz Instituto de Matemática Aplicada San Luis IMASL Universidad Nacional de San Luis and CONICET San Luis Argentina Departamento de Matemática Universidad Nacional de San Juan San Juan Argentina

This paper is focused on the analysis, in the framework of lattice theory, of the matchings obtained from restabilization (after disruption) of stable matchings. When the disruption is due to entry workers or closure of firms the unemployed workers make offers to firms. The stable matching obtained is the firms-worst stable matching of the set of stable matchings that the firms weakly prefer to the initial stable matching (i.e., before being disrupted by changes in the population). More precisely, their position within the lattice of stable matchings is shown.

Sleep Quality in non Dialysis Chronic Kidney Disease: Associated Factors and Influence on Prognosis

International Journal of Clinical Medicine 2016年第7期7卷 481-486页

Deficient sleep quality (SQ) has been linked with a higher hospitalization rate and mortality in dialysis patients, however the prevalence of sleep disorders and their influence on prognosis in non-dialysis chronic kidney disease (CKD) has been poorly investigated. The aim of this study was to assess factors related with SQ in CKD patients (stages I-IV) followed in a nephrology outpatient clinic as well as the long-term impact of SQ on patient’s outcome. Between January and May 2008, Pittsburgh Sleep Quality Index (PSQI) was self-administered by 122 patients (68 males and 54 females) with a mean age of 65 years. Patients were classified as “good” (global PSQI nd “poor” sleepers (global PSQI ≥ 6). We identified 66 (54%) poor sleepers (PS), characterized by an older age (66 ± 14.2 vs 57 ± 17.0, p nance (59% vs 26%, p nd worse renal function (49 ± 19.1 vs 57 ± 23.2 ml/min, p nificant correlation between phosphate and PSQI score (r = 0.234, p = 0.01), however no correlation with calcium or PTH. Vitamin D was also lower in PS (17 ± 7.2 vs 23 ± 15.1 ng/ml, p ntil June 2015, hospitalization rate was higher among PS (64% vs 44%, p n this period, there was also a trend towards higher mortality for PS (18% vs 16%). In summary, over 50% of CKD patients have poor SQ, which was associated with older age, female gender, worse renal function, lower vitamin D and higher phosphate levels. Deficient sleep was associated with a greater probability of hospitalization and might be a prognostic marker in CKD.
