As a part of the regression modeling, we conducted both “unadjusted” and “adjusted” regression analyses.

The “unadjusted” models only contain indicators for health insurance type. The “adjusted” models contain these insurance indicators plus the individual characteristics selleckchem listed in Exhibit 1. Exhibit 1. Survey Respondent Characteristics (Weighted) Results Survey Respondents Among the 3,014 survey respondents, 52% had private health insurance; 21% had Medicare (5% of all subjects were dual eligible for Medicare and Medicaid); 9% had Medicaid; and 18% were uninsured (Exhibit 1). Subjects differed considerably by insurance type with respect to socio-demographic, economic, and clinical characteristics. The percentage of private insurance beneficiaries with college degrees (53.5%) was higher

than the college-educated on Medicaid (17.2%) or who were uninsured (18%). More than half of all survey respondents were self-reported Internet users: 93% of privately insured adults and 56% of Medicare beneficiaries reported Internet use. Communication with health care providers occurs primarily offline (WITHOUT the Internet) Professional Advice (ALL RESPONDENTS):Thinking about the LAST time you had a serious health issue or experienced any significant change in your physical health… Did you get information, care or support from a doctor or other health care professional? All respondents were asked to indicate whether they sought professional advice (i.e., yes or no) and through what medium advice was sought (i.e., online, offline, or both online and offline). “Don’t know” and “Refused” options were available. Any respondents who were non-Internet users responding yes to this question were coded as yes,

offline responses. Substantially, more respondents reported seeking care through in-person visits or telephone calls than through online communication like email or Web messaging (Exhibit 2). Use of online consultations with a doctor varied across the insurance groups in unadjusted analysis (Exhibit 2), ranging from 12% of the Anacetrapib privately insured to 4% of uninsured adults. Exhibit 2. Percent Seeking Health Information from a Doctor, Any Online Efforts vs. Offline Only, by Insurance Type (unadjusted percent) After adjustment (Exhibit 3), Medicare beneficiaries had similar odds of seeking online consultations with doctors as privately insured adults (unadjusted OR=0.43, 95% CI: 0.37–0.50; adjusted OR=0.97, 95% CI: 0.80–1.17). After adjustment, Medicaid beneficiaries had greater odds (adjusted OR=1.45, 95% CI: 1.17–1.81) of seeking online physician consultations than privately insured adults (vs. having lower odds before adjustment, unadjusted OR=0.71, 95% CI: 0.59–0.85). Exhibit 3.

Due to the exclusion of proxy respondents for the Patient Activation Supplement, adjusted survey weights were created to

generalize estimates to the Medicare population.3 order SAR131675 With the survey weights, this sample represents 40,729,409 Medicare beneficiaries. Cut points for high, moderate, and low activation were assigned at +/– ½ standard deviation of the unweighted mean for each question set. The unweighted score was used to determine the cut points as the distribution did not differ from the weighted scores. Sensitivity analyses included altering the survey response thresholds and the activation cut points. For more details on how the scale was created, see Appendix B. Summary scores from the supplement have been used in other research to assign levels of patient activation (Butler et al., 2012), and our method of scale creation is similar to the method demonstrated by Hibbard and Cunningham (2008). Data were analyzed using SAS survey procedures, which take into account the complex survey design of the MCBS in reporting standard errors. Activation levels

were first described across sociodemographic characteristics. Next, exploratory data analysis for the model included univariate logistic regression for all variables under consideration for the model. Missing data on covariates was less than 1% for each variable and so an “all available” data analysis was utilized, resulting in 10,512 beneficiaries included in the model, representing 40.2 million beneficiaries with the use of the cross-sectional weights. The outcome of interest was low patient activation, defined by a patient

activation score under ½ standard deviation of the mean. Multicollinearity among predictor variables was assessed by fitting a multiple linear regression model and obtaining the variance inflation factor. Several models were fit and assessed using Akaike’s Information Criteria (AIC). Final covariates in the weighted model included Medicaid eligibility, marital status, education level, race, sex, age, self-reported health status, number of functional limitations measured by self-reported difficulty with activities of daily living (ADLs), and usual place of health Entinostat care. Influence diagnostics, including plots of Pearson residuals and leverage, were used to identify potential influential data points. Deletion of these observations resulted in no noticeable change to model coefficients; therefore, the observations were retained. Goodness of fit was assessed using the Hosmer-Lemeshow test and indicated good fit. Lastly, mean service utilization and costs were compared across activation levels. Cost and utilization data was only available for the fee-for-service (FFS) population of 7,370 survey participants who completed the supplement, representing 28,326,423 Medicare beneficiaries.

There are several effective methods for getting Rucaparib solubility efficient ontology similarity measure or ontology mapping algorithm in terms of ontology function. Wang et al. [11] considered the ontology similarity calculation in terms of ranking learning technology. Huang et al. [12] raised the fast ontology algorithm in order to cut the time complexity for ontology application. Gao and Liang [13] presented an ontology optimizing model such that the ontology function is determined by virtue of NDCG measure, and it is successfully applied in physics education.

Since the large part of ontology structure is the tree, Lan et al. [14] explored the learning theory approach for ontology similarity calculating and ontology mapping in specific setting when the structure of ontology graph has no cycle. In the multidividing ontology setting, all vertices in ontology graph or multiontology graph are divided into k parts corresponding to the k classes of rates. The rate values of all classes are determined by experts. In this way, a vertex in a rate a has larger score than any vertex in rate b (if 1 ≤ a < b ≤ k) under the multidividing ontology function f : V → R. Finally, the similarity between two ontology vertices

corresponding to two concepts (or elements) is judged by the difference of two real numbers which they correspond to. Hence, the multidividing ontology setting is suitable to get a score ontology function for an ontology application if the ontology is drawn into a noncycle structure. Gao and Xu [15] studied the uniform stability of multidividing ontology algorithm and obtained the generalization bounds

for stable multidividing ontology algorithms. In the above described ontology learning algorithms, their optimal ontology function calculation model or its solution strategy is done by gradient calculation. Specifically, the ontology gradient learning algorithm obtains the ontology function vector f→=(f1,f2,…,fn)T which maps each vertex into a real number (the value fi corresponds to vertex vi). In this sense, it is good or bad policy gradient calculation algorithm that will determine the merits of the ontology algorithm. In this paper, we raise an ontology gradient learning algorithm for ontology similarity measuring and ontology mapping in multidividing setting. The organization of the rest paper is as follows: the notations and ontology gradient Batimastat computing model are directly presented in Section 2; the detailed description of new ontology algorithms is shown in Section 3; in Section 4, we obtain some theoretical results concerning the sample error and convergence rate; in Section 5, two simulation experiments on plant science and humanoid robotics are designed to test the efficiency of our gradient computation based ontology algorithm, and the data results reveal that our algorithm has high precision ratio for plant and humanoid robotics applications. 2.
