Patienten gut geplant entlassen

Expertenstandard Entlassungsmanagement – Die Entlassung aus Krankenhaus oder Rehaklinik stellt viele Patienten und Angeh?rige vor eine Belastungsprobe. Wie soll der Alltag mit einer chronischen Krankheit oder Behinderung bew?ltigt werden? Noch zu h?ufig bleiben die Betroffenen mit ihren Problemen allein. Abhilfe verspricht ein gut geplantes Entlassungsmanagement, das alle Beteiligten einbindet.

Local Expected Shortfall-Hedging in Discrete Time

This paper proposes a self-financing trading strategy that minimizes theexpected shortfall locally when hedging a European contingentclaim. A positive shortfall occurs if the hedger is not willing to follow a perfect hedging or a superhedging strategy. In contrast to the classicalvariance criterion, the expected shortfall criterion dependsonly on undesirable outcomes where the terminal value of the writtenoption exceeds the terminal value of the hedgeportfolio. Searching a strategy which minimizes the expected shortfallis equivalent to the iterative solution of linear programs whosenumber increases exponentially with respect to the number of tradingdates. Therefore, we partition this complex overall problem intoseveral one-period problems and minimize the expected shortfall onlylocally, i.e., only over the next trading period. This approximation is quite accurate and the number of linear programs to be solved increases only linearly with respect to the number of trading dates.     

Where Are They Now? Tracking the Ph.D. Class of 1997

We report early career outcomes of economics Ph.D.s by tracking the U.S. class of 1996-1997. We examine employment outcomes, work activities, salaries, and graduates' attitudes toward their jobs. By 2003, all of the respondents were employed, although almost half changed employers during the six years. Salaries of the cohort increased at an average annual rate of 8.2% from 1997 through 2003. Academic-year salaries rose about 5.7% per year, whereas private sector salaries skyrocketed at 15% per year. Finally, the median salaries of first-year full-time permanent 9- to 10-month academic economists hired in 2002-2003 actually exceed the median 2003 salaries of their counterparts initially hired in 1997-1998. Some of this apparent salary inversion reflects a different mix of employers and departments between the two cohorts, with the younger group securing relatively more jobs at higher-paying institutions.     

Thailand’s third five year plan

Thailand’s third Development Plan sketches the framework within which it is intended to press forward with the country’s economic and social development during 1972–76. The present article surveys and critically discusses the main traits of the new Plan.     

Optimal Strategies in 2-Stage Sampling

In many survey situations simple random sampling of units and estimation of a total of interest by the expansion estimator are attractive methods, at least at first sight. Considering cost aspects suggests rather to use multiple stage sampling which, in general, is cheaper, but less effective. The design effect is an adequate criterion of the decrease of efficiency. We discuss this criterion for clusters (primary units) of equal size and derive exact conditions for a decrease of efficiency. The equality condition for cluster sizes seems not to be very restrictive, because in many cases one will be interested in clusters of approximately the same size, or, if sizes differ essentially, the clusters are partitioned into strata according to their sizes and the procedures for different strata are independent, each dealing with clusters of equal size or nearly so. In the context considered the use of the Horvitz–Thompson estimator is quite general. We examine a class of estimators with the Horvitz–Thompson estimator and a straight forward modification of it as special elements. As for the design effect all elements of the class are very similar, as for other aspects such as admissibility there are remarkable differences.     

η-Pseudolinearity

The notion of η-pseudolinearity is introduced. First, some characterizations of an η-pseudolinear function are obtained. Then characterizations of the solution set of an η-pseudolinear program are derived. The paper generalizes various results on pseudolinear functions and programs.
