Aggregated dynamic demand equations for specialistic-outpatient medical care:(Estimated from a time-series of cross-sections)

In this paper a dynamic model is presented which describes the development of the demand for specialistic medical care in The Netherlands, during the period 1960-1972. The "regionally correlated, time-wise auto-regressive" model is consistently estimated from a time-series of cross-sections, using a modified Aitken estimator. The dependent variables are the number of publicly insured patients referred from general care to specialistic care, and the amount of care consumed per patient referred. As independent variables we took demographic factors, the supply of different levels of medical care and the insurance system. The estimation results show a.o. important substitution possibilities between general and specialistic care, and a significant influence of supply and supply-related variables on the demand for specialistic care.</p

Sharing a Top Manager’s Experience with the Next Generation: The Use of Electronic Discussions and Short Video Fragments in Teaching

In: A.J. Kallenberg and M.J.J.M. van de Ven (Eds), 2002, The New Educational Benefits of ICT in Higher Education: Proceedings. Rotterdam: Erasmus Plus BV, OECR ISBN 90-9016127-9This paper presents an effective educational method to transfer managerial knowledge to students. This method consists among other of online discussions between small groups of students and video clips of lectures. The set-up of the course and the ICT-tool used in the course were evaluated for two years through a questionnaire among the students. The results show that the applied e-learning concept is highly appreciated and serves as an effective tool to exchange knowledge

Are tearful individuals perceived as less competent? Probably not

What are the social signals of emotional tears? This question has fascinated scholars ever since Darwin. Studies have suggested several interpersonal effects of emotional tears. A recent study by Van de Ven, Meijs, and Vingerhoets (2017) presented evidence in three studies that tearful individuals are perceived as warmer, but also less competent than their non-tearful counterparts. However, the competence effect was relatively small, and a recent replication failed to find such an effect in two different populations while the warmth effect was replicated (Zickfeld &amp; Schubert, 2018). This questions the generalizability of the effect of tears on perceived competence. To test whether individuals expressing emotional tears are really perceived as less competent and what boundary conditions such an effect might have, we specified a decision tree of three different studies in which we test differences between the original reference study and the replication. We replicated previous findings of the perceived (in)competence in Study 1 (n = 531) but observed a considerably smaller non-significant effect when proceeding to Study 2 (n = 471), which increased the number of stimuli. The earlier and now repeated replication failure can therefore likely be attributed to an increased variation in stimulus material. We conclude that there is not enough evidence to argue that one social outcome of tears signals a relative lack of competence as the effect seems to depend on the specific stimuli used.info:eu-repo/semantics/acceptedVersio

The complex nature of the nuclear star cluster in FCC 277

Recent observations have shown that compact nuclear star clusters (NSCs) are present in up to 80% of galaxies. However, detailed studies of their dynamical and chemical properties are confined mainly to spiral galaxy hosts, where they are more easily observed. In this paper we present our study of the NSC in FCC 277, a nucleated elliptical galaxy in the Fornax cluster. We use a combination of adaptive optics assisted near-infrared integral field spectroscopy, Hubble Space Telescope imaging, and literature long slit data. We show that while the NSC does not appear to rotate within our detection limit of ~6 km/s, rotation is detected at larger radii, where the isophotes appear to be disky, suggesting the presence of a nuclear disk. We also observe a distinct central velocity dispersion drop that is indicative of a dynamically cold rotating sub-system. Following the results of orbit-based dynamical modelling, co-rotating as well as counter-rotating stellar orbits are simultaneously needed to reproduce the observed kinematics. We find evidence for varying stellar populations, with the NSC and nuclear disk hosting younger and more metal rich stars than the main body of the galaxy. We argue that gas dissipation and some level of merging have likely played an important role in the formation of the nucleus of this intermediate-mass galaxy. This is in contrast to NSCs in low-mass early- type galaxies, which may have been formed primarily through the infall of star clusters.Comment: 10 pages, 11 figures, MNRAS in press, changes to this version: co-author adde

Can Observers Predict Trustworthiness?

We investigate whether experimental subjects can predict behavior in a prisoner's dilemma played on a TV show. Subjects report probabilistic beliefs that a player cooperates, before and after the players communicate. Subjects correctly predict that women and players who make a voluntary promise are more likely to cooperate. They are able to distinguish truth from lies when a player is asked about her intentions by the host. Subjects are to some extent able to predict behavior; their beliefs are 7~percentage points higher for cooperators than for defectors. We also study their Bayesian updating. Beliefs do not satisfy the martingale property and display mean reversion

Which assessment tools address the categories of the Brief ICF Core Set for Hand Conditions?

Introduction The purpose of this study was to explore whether assessment tools address aspects that are relevant according to the Brief ICF Core Set for Hand Conditions (BICF-CS). Methods Assessment tools meant to assess functioning and/or environmental factors in adults with hand conditions were reviewed. MEDLINE and CINAHL databases, previously published reviews, the book Clinical Assessment Recommendations of the ASHT, and websites of assessment tools were used for the content comparison and linking to the 23 categories of the BICF-CS. The updated version of the linking rules was applied by two reviewers. Results Forty-six assessment tools, known within the areas of hand therapy and hand surgery, were linked to the 23 categories of the BICF-CS. Regarding Body functions and body structures, the categories that were most frequently addressed were b730 “Muscle power functions,” b280 “Sensation of pain,” b710 “Mobility of joint functions,” and s730 “Structure of upper extremity.” Regarding Activities and Participation, d440 “Fine hand use” was addressed mostly and 25 assessment tools (with a total of 146 items) were linked to this category. Regarding Environmental Factors, only one assessment tool was identified that could be linked to two categories. Fifteen points of discussion were encountered in the linking process. Conclusions Content comparison of 46 assessment tools revealed that 19 of the 23 categories of the BICF-CS were addressed. The environmental factors were hardly addressed

A SAURON view of galaxies

We have measured the two-dimensional kinematics and line-strength distributions of 72 representative nearby early-type galaxies, out to approximately one effective radius, with our panoramic integral-field spectrograph SAURON. The resulting maps reveal a rich variety in kinematical structures and linestrength distributions, indicating that early-type galaxies are more complex systems than often assumed. We are building detailed dynamical models for these galaxies, to derive their intrinsic shape and dynamical structure, and to determine the mass of the supermassive central black hole. Here we focus on two examples, the compact elliptical M32 and the E3 galaxy NGC4365. These objects represent two extreme cases: M32 has very regular kinematics which can be represented accurately by an axisymmetric model in which all stars rotate around the short axis, while NGC4365 is a triaxial galaxy with a prominent kinematically decoupled core, with an inner core that rotates about an axis that is nearly perpendicular to the rotation axis of the main body of the galaxy. Our dynamical models for these objects demonstrate that two-dimensional observations are essential for deriving the intrinsic orbital structure and dark matter content of galaxies.Comment: 7 pages (3 figures, full resolution Fig. 1 available at http://www.strw.leidenuniv.nl/~verolme/M32.ps).

R&D partnership portfolios and the inflow of technological knowledge

This article links research on parallel search and joint R&D to contribute a portfolio perspective to the study of knowledge flows within interfirm R&D partnerships. In a longitudinal analysis of firms engaged in R&D partnerships relating to information technology between 1975 and 1999, we show that the size of a firm's R&D partnership portfolio and its share of novel partners both have an inverted U-shaped effect on the inflow of technological knowledge from the firm's R&D partners. We also show how these direct effects vary as a function of the level of technological uncertainty within the portfolio
