The Physician-Patient Relationship Revisited - the Patient's View

The importance of the physician-patient relationship for the health care market is beyond controversy. Most theoretical work is done in a principal-agent framework, dealing with moral hazard problems. Recent work emphasizes a two-sided asymmetric information relationship between physician and patient (double moral hazard). In contrast to most work looking only at the physician's perspectives, our paper concentrates on the patient's view. Estimation results using panel data support the hypotheses that physician consultation and health-relevant behavior are not stochastically independent. This means that health care demand is determined by the patient and not only by the physician. In the recursive bivariate probit model, the patient’s health-relevant behavior has a significant positive influence on the probability of a physician visit. This should be taken into account in the discussion that primary care physicians should function as gatekeepers.physician-patient relationship, health behavior, bivariate probit

Health Relevant Behavior and its Impact on the Physician-Patient Relationship

The importance of the physician-patient relationship for the health care market is beyond controversy. Recent work emphasizes a two-sided asymmetric information relationship between physician and patient. In contrast to most work looking only at the physician's perspective, our paper concentrates on the patient's view. Estimation results support the hypotheses that physician consultation and health relevant behavior are not stochastically independent. In the recursive bivariate probit model, patient’s health relevant behavior has a significant influence on the probability of a physician visit. This means that health care demand and not only the contact decision is determined by both, patient and physician.physician-patient relationship, health behavior, bivariate probit panel

I feel good! Gender differences and reporting heterogeneity in self-assessed health

For empirical analysis and policy-oriented recommendation, the precise measurement of individual health or well-being is essential. The problem with variables based on questionnaires such as self-assessed health is that the answer may depend on individual reporting behaviour. Moreover, if individual‟s health perception varies with certain attitudes of the respondent reporting heterogenei-ty may lead to index or cut-point shifts of the health distribution, causing estimation problems. We analyse the reporting behaviour of individuals on their self-assessed health status, a five-point categorical variable. We explore observed heterogeneity in categorical variables and include unob-served individual heterogeneity using German panel data. Estimation results show different im-pacts of socioeconomic and health related variables on the five subscales of self-assessed health. Moreover, the answering behaviour varies between female and male respondents, pointing to gen-der specific perception and assessment of diseases. Reporting behaviour on self-assessed health questions in surveys is problematic due to a possible heterogeneity. Hence, in case of reporting heterogeneity, using self-assessed measures in empirical studies may be misleading or at least ambiguous.reporting heterogeneity, generalized ordered probit, self-assessed health

Position control of an industrial robot using an optical measurement system for machining purposes

A series of mechanical properties and disturbances limit the accuracy achievable in robotic applications. External control of the end effector position is commonly known as being an appropriate mean to increase accuracy. This paper presents an approach for position control of industrial robots using the pass-through between an industrial CNC and servomotors. A CNC-controlled robot is used together with an external optical measurement system to close the feedback loop of robot end effector and robot controller in order to improve robot accuracy. For short cycle times and implementation reasons a PLC is used for signal processing and control implementation. The relevance of the approach is outlined in experiments. The robot behaviour in free space motion and in machining application is analysed with the optical measurement system and a CMM

Alte Texte in neuen Medien : aktuelle Projekte und Projektvorhaben der Universitätsbibliothek Leipzig

Die Universitätsbibliothek Leipzig (UBL) steht zur Sächsischen Akademie der Wissenschaften in einer speziellen Beziehung: Sie ist deren Archivbibliothek. Außerdem versorgt sie natürlich die Wissenschaftler der Akademie mit der von ihnen gewünschten wissenschaftlichen Literatur. Seit dem 19. Jahrhundert – dem Jahrhundert der Gründung der Sächsischen Akademie der Wissenschaften zu Leipzig – hat die Universitätsbibliothek Leipzig eine große Zahl an Schätzen des Weltschrifterbes erhalten, die sie bis heute bewahrt. Nun kommen im 21. Jahrhundert neue technische Möglichkeiten hinzu, und eine kleine Revolution ist perfekt: Alte Texte können in neuen Medien präsentiert bzw. veröffentlicht werden, die Erschließungsleistung der Bibliothekare kann unmittelbar für die Forschung bereitgestellt werden, darüber hinaus sind die Originale im Tresor der Bibliotheca Albertina gerade durch ihre erheblich verbesserte Zugänglichkeit über digitale Sekundärformen besser geschützt. Die laufenden Projekte der Universitätsbibliothek kann man seit Anfang 2008 auf der Homepage der UBL (www.ub.uni-leipzig.de) eigens aufgelistet finden (s. dort unter ›Projekte‹). Sie lassen sich in vier Gruppen gliedern und sollen im Folgenden kurz erläutert werden. Neuere Projektvorhaben werde ich im Anschluss daran erläutern. Die vier thematisch-kulturellen Gruppen, innerhalb deren Katalogisierungs-, Erschließungs- und Forschungsleistungen an der Universitätsbibliothek Leipzig erbracht werden, sind 1. Texte der Antike, 2. Texte und Textträger des Mittelalters, 3. Texte aus dem orientalischen Kulturraum und 4. Quellentexte zur Wissenschaftsgeschichte der Neuzeit

Characterization of the murine cytomegalovirus genes encoding the major DNA binding protein and the ICP18.5 homolog

In several herpesviruses the genes for the major DNA binding protein (MDBP), a putative assembly protein, the glycoprotein B (gB), and the viral DNA polymerase (pol) coliocate. In murine cytomegalovirus (MCMV), two members of this gene block, pol (Elliott, Clark, Jaquish, and Spector, 1991, Virology 185, 169-186) and gB (Rapp, Messerle, BOhler, Tannheimer, Keil, and Koszinowski, 1992, J. Virol., 66,4399-4406) have been characterized. Here the two other MCMV genes are characterized, the gene encoding the MDBP and the ICP18.5 homolog encoding a putative assembly protein. Like in human cytomegalovirus (HCMV) the genes order is pol, gB, ICP18.5, and MDBP. The 4.2-kb MDBP mRNA is expressed first in the early phase, whereas the 3.0-kb ICP18.5 mRNA is a late transcript. The open reading frame of the MDBP gene has the capacity of encoding a protein of 1191 amino acids with a predicted molecular mass of 131.7 kDa. The MCMV ICP18.5 ORF is translated into a polypeptide of 798 amino acids with a calculated molecular mass of 89.1 kDa. Comparison of the amino acid sequences of the predicted proteins of MCMV with the respective proteins of HCMV, Epstein-Barr virus (EBV), and herpes simplex virus type-1 (HSV-1) reveals a striking homology ranging from 72% (HCMV), 50% (EBV), to 45% (HSV-1) for the MDBP sequence and from 74% (HCMV), 51 % (EBV), to 49% (HSV-1) for the ICP18.5 sequence. These results establish the elose relationship of the two cytomegaloviruses, and underline the usefulness of the murine model for studies on the biology of the CMV infection

Eclecticism rediscovered: [Rezension zu: ]Michael Albrecht, Eklektik. Eine Begriffsgeschichte mit Hinweisen auf die Philosophie- und Wissenschaftsgeschichte, Stuttgart 1994 und Patrice Vermeren, Victor Cousin. Le Jeu de La Philosophie et de l''Etat, Paris 1995

Whatever the significance of the postmodern state of mind, recent views concerning philosophical eclecticism are largely the product of researches into the history of philosophy. There is an obvious inclination of today''s intellectual historians to investigate background figures of European modernity. The increasing willingness of historians to enlarge the notion of philosophy in both its disciplinary and historical definition seems to be in agreement with a similar disposition of contemporary philosophers. As we can learn from Michael Albrecht''s and Patrice Vermeren''s books, a critical appreciation of eclecticism throws light both on the conditions of contemporary philosophizing and on the politics of philosophy in the modern age

Coherent Interaction of a Single Fermion with a Small Bosonic Field

We have experimentally studied few-body impurity systems consisting of a single fermionic atom and a small bosonic field on the sites of an optical lattice. Quantum phase revival spectroscopy has allowed us to accurately measure the absolute strength of Bose-Fermi interactions as a function of the interspecies scattering length. Furthermore, we observe the modification of Bose-Bose interactions that is induced by the interacting fermion. Because of an interference between Bose-Bose and Bose-Fermi phase dynamics, we can infer the mean fermionic filling of the mixture and quantify its increase (decrease) when the lattice is loaded with attractive (repulsive) interspecies interactions.Comment: 4+ pages, 5 figures, updated to <a href="http://dx.doi.org/10.1103/PhysRevLett.106.115305">published version</a
