Condcrcet's criterion states that an alternative defeats every other by a simple majority is the socially optimal choice. Condorcet argued if object of voting to determine “best” decision for society but voters sometimes make mistakes in their judgments, then (if it exists) statistically most likely be best Strictly speaking, this claim not true; some situations Bordas rule gives sharper estimate alternative. Nevertheless, did propose novel and correct finding ranking alternatives. This...
Condorcet’s principle of choosing the majority alternative whenever one exists is violated not only by Borda’s rule but any scoring method; nevertheless essential property functions—“consistency” outcome under aggregation subgroups—is shown to be compatible with principle. Moreover these two properties, suitably interpreted, together neutrality, determine a unique known as Kemeny’s rule.
Let a committee of voters be considering finite set $A = \{ {a_1 ,a_2 , \cdots ,a_m } \}$ alternatives for election. Each voter is assumed to rank the according his preferences in strict linear order. A social choice function rule which, every with specified preference orders, assigns nonempty subset A, interpreted as "winners". consistent if, whenever two disjoint committees meeting separately choose same winner(s), then jointly precisely these winner(s). The symmetric if it does not depend...
Study objectiveThe goal of this study is to create a predictive, interpretable model early hospital respiratory failure among emergency department (ED) patients admitted with coronavirus disease 2019 (COVID-19).MethodsThis was an observational, retrospective, cohort from 9-ED health system adult severe acute syndrome 2 (COVID-19) and oxygen requirement less than or equal 6 L/min. We sought predict within 24 hours admission as defined by greater 10 L/min low-flow device, high-flow noninvasive...
Different methods for allocating the joint costs of water supply projects among users are compared on basis certain commonsense principles equity. We contrast separable costs‐remaining benefits (SCRB) method with simple proportional allocation schemes and more sophisticated from cooperative game theory, including Shapley value variants core. Advantages disadvantages in practice examined using a regional system Sweden. It is argued that these provide useful framework choosing intelligently...
AbstractAbstractThe problem of apportionment is explained together with an account the methods used by United States Congress beginning first decennial 1792. Fairness and historical precedent dictate that several properties must be satisfied any method which may deemed acceptable. It shown presently violates one these a new procedure, quota method, unique satisfying essential properties.
Severe acute respiratory syndrome virus (SARS-CoV-2) has infected millions of people worldwide. Our goal was to identify risk factors associated with admission and disease severity in patients SARS-CoV-2.
Methods to allocate seats in proportional representation systems are investigated terms of underlying common-sense properties. Important among these concepts stability, coalition encouragement and schism encouragement. In addition, a new concept uniformity is introduced which seems inherent the very idea word “method, ” it shown that this essentially equivalent previously property called consistency. These other criteria uniquely determine certain methods. particular, Jefferson method...
Abstract The emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants continues to shape the disease 2019 (Covid-19) pandemic. detection and rapid spread SARS-CoV-2 ‘ Omicron’ variant (lineage B.1.1.529) in Botswana South Africa became a global concern because it contained 15 mutations spike protein immunogenic receptor binding domain was less neutralized by sera derived from vaccinees compared previously dominant Delta variant. To investigate if Omicron is more...
The Jefferson method of apportionment is characterized by three properties; consistency, house monotonicity, and satisfying lower quota. smallest divisors similarly substituting upper quota for
Abstract Diagnosis codes are used to study SARS-CoV2 infections and COVID-19 hospitalizations in administrative electronic health record (EHR) data. Using EHR data (April 2020–March 2021) at the Yale-New Haven Health System three hospital systems of Mayo Clinic, computable phenotype definitions based on ICD-10 diagnosis (U07.1) were evaluated against positive SARS-CoV-2 PCR or antigen tests. We included 69,423 patients Yale 75,748 Clinic with either a code test. The precision recall for test...
A (generalized) Huntington method for apportioning representatives among states, or seats parties, is one which distributes by using a rank index that determines how deserving state, party, to receive the next available seat. characterization of these methods given two basic properties; consistency and monotonicity. The arguments used establish this result are combinatorial in nature use classical theorems concerning partial orders their representation real-valued function.
A model is presented to describe how a calculating lobbyist should allocate resources most effectively among voters in legislature, given that there no opposition lobbying effort. Equilibrium prices exist provided veto player. When opposition, different and concept of equilibrium result. The outcome this treated for case when the opposing forces have unequal resources. This results an which essentially nucleolus. Application made us Presidential campaigning Electoral College, setting...
