TL;DR: In this article, the authors extend Mousseau et al. (2003) to incorporate information about the confidence attached to each assignment example, hence providing inconsistency resolutions that the DMs are most likely to accept.
Abstract: Sorting models consist in assigning alternatives evaluated on several criteria to ordered categories. To implement such models it is necessary to set the values of the preference parameters used in the model. Rather than fixing the values of these parameters directly, a usual approach is to infer these values from assign- ment examples provided by the decision maker (DM), i.e., alternatives for which (s)he specifies a required category. However, assignment examples provided by DMs can be inconsistent, i.e., may not match the sorting model. In such situations, it is necessary to support the DMs in the resolution of this inconsistency. In this paper, we extend algorithms from Mousseau et al. (2003) that calculate different ways to remove assignment examples so that the information can be represented in the sorting model. The extension concerns the possibility to relax (rather than to delete) assignment examples. These algorithms incorporate information about the confidence attached to each assignment example, hence providing inconsistency resolutions that the DMs are most likely to accept.

TL;DR: It is found that longevity in individuals with DS will necessitate complex adult and geriatric care and more evidenced-based and standardized follow-up could support better long-term comorbidity management and dementia care among aging adults with DS.
Abstract: Importance As the life expectancy of people with Down syndrome (DS) has markedly increased over the past decades, older adults with DS may be experiencing a higher incidence of aging conditions. In addition to longevity, the amyloid precursor protein gene located on chromosome 21 places individuals with DS at a high risk for developing Alzheimer disease. Yet, few studies have determined prevalence of dementia and comorbidities among older people with DS. Objective To determine the prevalence of dementia and aging-related comorbidities in older adult individuals with DS. Design, Setting, and Participants Cross-sectional analysis of 2015 California Medicare claims data. We examined 1 year of cross-sectional Medicare claims data that included 100% of Californian Medicare beneficiaries enrolled in both Medicare Part A and B in 2015. Of these 3 001 977 Californian Medicare beneficiaries 45 years or older, 878 individuals were identified as having a diagnosis of DS. Data were analyzed between April 2017 and February 2018. Main Outcomes and Measures The frequency of DS dementia was assessed across different age categories. The number and frequency of 27 comorbidities were compared among individuals with DS with and without dementia and by age and sex groups. Results A total of 353 DS individuals (40%) were identified as having dementia diagnoses (mean, 58.7 years; 173 women [49%]) and 525 without dementia diagnoses (mean, 55.9 years; 250 women [48%]). The frequency of DS dementia among those 65 years or older rose to 49%. The mean number of comorbidities per individual increased with age in general. Comorbid conditions were more numerous among those with dementia compared with those with DS without dementia (mean, 3.4 vs 2.5, respectively), especially among those younger than 65 years. In particular, 4 treatable conditions, hypothyroidism, epilepsy, anemia, and weight loss, were much more frequent in DS dementia. Conclusions and Relevance Older Medicare beneficiaries in California with DS, especially those with dementia, have a high level of multimorbidity including several treatable conditions. While DS follow-up has long been confined to the pediatric sphere, we found that longevity in individuals with DS will necessitate complex adult and geriatric care. More evidenced-based and standardized follow-up could support better long-term comorbidity management and dementia care among aging adults with DS.

21 May 2013TL;DR: In this paper, a generalized 1d periodic SPDE of Burgers type was studied, where the noise provided a regularizing effect allowing to prove existence and suitable estimates when the noise > 1/2.
Abstract: We study a generalized 1d periodic SPDE of Burgers type: $$\begin{aligned} \partial _t u =- A^\theta u + \partial _x u^2 + A^{\theta /2} \xi \end{aligned}$$
where $$\theta > 1/2$$
, $$-A$$
is the 1d Laplacian, $$\xi $$
is a space–time white noise and the initial condition $$u_0$$
is taken to be (space) white noise. We introduce a notion of weak solution for this equation in the stationary setting. For these solutions we point out how the noise provide a regularizing effect allowing to prove existence and suitable estimates when $$\theta >1/2$$
. When $$\theta >5/4$$
we obtain pathwise uniqueness. We discuss the use of the same method to study different approximations of the same equation and for a model of stationary 2d stochastic Navier–Stokes evolution.

TL;DR: In this article, the authors show that the abnormal returns of sovereign wealth fund (SWF) equity investments in publicly traded firms are positive but lower than those of comparable private investments.
Abstract: We document that announcement-period abnormal returns of sovereign wealth fund (SWF) equity investments in publicly traded firms are positive but lower than those of comparable private investments. Further, SWF investment targets suffer from declining return on assets and sales growth over the following three years. Our results are robust to controls for target and deal characteristics and are not driven by SWF target selection criteria. Larger discounts are associated with SWFs taking seats on boards of directors and with SWFs under strict government control acquiring greater stakes, supporting the hypothesis that political influence negatively affects firm value and performance
