Increasingly ‘Irrational’ Party Systems: Evidence that There Are Increasingly More Than Two Parties at the District Level

Chest Pain Patients at Veterans Hospitals Are Increasingly More Likely to Be Observed Than Admitted for Short Stays

Observation stays are an outpatient service used to diagnose and treat patients for extended periods of time while a decision is made regarding inpatient admission or discharge. Although the use of observation stays is increasing, little is known about which patients are observed and which are admitted for similar periods of time as inpatients. The aim was to identify patient characteristics as...

Abstract—intrusion Detection Systems Are Increasingly a Key

Intrusion Detection Systems are increasingly a key part of systems defense. Various approaches to Intrusion Detection are currently being used, but they are relatively ineffective. Artificial Intelligence plays a driving role in security services. This paper proposes a dynamic model Intelligent Intrusion Detection System, based on specific AI approach for intrusion detection. The techniques tha...

There are no Barker arrays having more than two dimensions

Davis, Jedwab and Smith recently proved that there are no 2-dimensional Barker arrays except of size 2×2. We show that the existence of a (d+1)-dimensional Barker array implies the existence of a d-dimensional Barker array with the same number of ±1 elements. We deduce that there are no Barker arrays having more than two dimensions, as conjectured by Dymond in 1992.

When parties are not teams: party positions in single-member district and proportional representation systems

Theoretical analyses of party positions commonly assume that parties act as teams to maximize their legislative representation. This assumption runs counter to another line of theorizing in which individual legislators maximize their own chances of winning reelection. To resolve this tension, the paper presents a model of party platform choice that relaxes only the assumption that parties are t...
