What do patients think after lung-transplantation about their self, body, and social network? A quantitative analysis of categorical interview data

Objective: Psychosocial aspects have been investigated in transplant medicine mainly by the means of various structured questionnaires. To date only few interview data are available on patients thoughts about their self, the transplanted lung or the medication, and the relationship between these thoughts and compliance or gender. Methods: Twenty patients were interviewed after transplantation about their perceptions on self, body, transplanted lung, medication and social network. Their compliance was rated by the attending physicians. The overall interrater-reliability for the category groups was Kappa=.8. The article presents quantitative results of the content analysis. Results: Statements were made most frequently about the patients' social network and their self, and significantly less frequently about their body, lung and medication. "Closeness", "distance" and "depression" where main issues that these patients were dealing with. "Closeness" and "distance" played major roles in interpersonal relationships as well as in the relationship to the new lung. Depression mainly had to do with health burdens and the psychosocial consequences of the transplantation (e.g. financial worries). Women made significantly more statements about their social network than men; furthermore they formulate more accented emotional evaluations. Patients with low compliance were more frequently preoccupied with their self, their body as well as the experience of "dependence" and "achievement" than patients with high compliance; also low compliant patients made more critical statements. Conclusions: For lung transplant recipients social relationships are the prime topic of their daily experience. With respect to compliance behaviour, special attention should be paid to the patients' self and body perception as well as to their experience of dependence. These results should be confirmed in studies with larger sample sizes

Algorithm Engineering in Robust Optimization

Robust optimization is a young and emerging field of research having received a considerable increase of interest over the last decade. In this paper, we argue that the the algorithm engineering methodology fits very well to the field of robust optimization and yields a rewarding new perspective on both the current state of research and open research directions. To this end we go through the algorithm engineering cycle of design and analysis of concepts, development and implementation of algorithms, and theoretical and experimental evaluation. We show that many ideas of algorithm engineering have already been applied in publications on robust optimization. Most work on robust optimization is devoted to analysis of the concepts and the development of algorithms, some papers deal with the evaluation of a particular concept in case studies, and work on comparison of concepts just starts. What is still a drawback in many papers on robustness is the missing link to include the results of the experiments again in the design

Compressed representation of a partially defined integer function over multiple arguments

In OLAP (OnLine Analitical Processing) data are analysed in an n-dimensional cube. The cube may be represented as a partially defined function over n arguments. Considering that often the function is not defined everywhere, we ask: is there a known way of representing the function or the points in which it is defined, in a more compact manner than the trivial one

Measurement of the production cross section for Z gamma -> nu(nu)over-bar gamma in pp collisions at √s=7 TeV and limits on ZZ gamma and Z gamma gamma triple gauge boson couplings

This article is the pre-print version of the final published paper that is available from the link below.A measurement of the Z → vvγ cross section in pp collisions at root s = 7TeV is presented, using data corresponding to an integrated luminosity of 5.0 fb-1 collected with the CMS detector. This measurement is based on the observation of events with an imbalance of transverse energy in excess of 130 GeV and a single photon in the absolute pseudorapidity range |n| < 1:4 with transverse energy above 145 GeV. The Z →vvγ production cross section is measured to be 21.1±4.2 (stat:)±4.3 (syst:)±0.5 (lum:) fb, which agrees with the standard model prediction of 21.9±1.1 fb. The results are combined with the CMS measurement of Z production in the l+l- γ final state (where l is an electron or a muon) to yield the most stringent limits to date on triple gauge boson couplings: |hZ3|< 2.7 x 10-3, |hZ4| < 1,3 x 10-5 for ZZγ and |hγ3| < 2.9 x10-3, |hγ4| < 1.5 x 10-5 for Zγγ couplings
