Do Dutch Musea Compete Or Cooperate?

This paper looks into the effect of distance on market shares of Dutch museums. To this end, we assume a generic distance decay function for all museums. In addition, we allow for spatial dependence between museums to account for local competition or synergy effects. Using a unique transaction database with the visiting behavior of 80,821 museum cardholders to 108 Dutch museums, we are able to calculate market shares of each museum in all 484 Dutch municipalities. To account for possible measurement error in the market shares, we adopt a spatial two error component model. Finally, we allow for additional heterogeneity by segmenting the 108 museums using a mixture approach. Without segmenting, preliminary results indicate positive spatial dependence between museums, which points to the conclusion that -- in general -- museums benefit from each others presence.

Questionbank: computer supported self-questioning

Self-questioning is a learning strategy that focuses on knowledge acquisition and concept comprehension by the learner generating questions. This paper describes the development of an internet-based application that supports self-questioning, referred to as Questionbank, and presents a case study of its implementation, and an evaluation. The findings in this paper suggest that Questionbank is a very useful tool to support self-questioning, but that the system in itself is not sufficient to improve the learning experience of students. Additional instructional measures for this are suggested

Design of Cross-chain Internet Order Fulfillment Centres

Many consumers have embraced the option of ordering via the Internet, which has resulted in an enormous increase in direct orders compared to the times when direct ordering was done by catalogue and phone. The fulfillment process in the supply chain is an important factor for these consumers impacting how long they must wait between ordering and delivery. This fact has significantly increased the importance of the back-end fulfillment process. We present a novel supply chain design to enable cross-chain coordination of order fulfillment operations for internet sales. Shared warehousing facilities are used more and more to achieve competitive advantage. This situation asks for new models to enable a smooth warehousing process for each web shop, but at the same time to ensure overall efficiency and effectiveness. This paper introduces a layout model for shared operations under one roof by simultaneously optimizing the overall facility layout and the area layout

Action Plan to enhance self-management and early detection of exacerbations in COPD patients; a multicenter RCT

<p>Abstract</p> <p>Background</p> <p>Early detection of exacerbations by COPD patients initiating prompt interventions has shown to be clinically relevant. Until now, research failed to identify the effectiveness of a written individualized Action Plan (AP) to achieve this.</p> <p>Methods/Design</p> <p>The current multicenter, single-blind RCT with a follow-up period of 6 months, evaluates the hypothesis that individualized AP's reduce exacerbation recovery time. Patients are included from regular respiratory nurse clinics and allocated to either usual care or the AP intervention. The AP provides individualized treatment prescriptions (pharmaceutical and non-pharmaceutical) related to a color coded symptom status (reinforcement at 1 and 4 months). Although usually not possible in self-management trials, we ensured blinding of patients, using a modified informed consent procedure in which patients give consent to postponed information. Exacerbations in both study arms are defined using the Anthonisen symptom diary-card algorithm. The Clinical COPD Questionnaire (CCQ) is assessed every 3-days. CCQ-recovery time of an exacerbation is the primary study outcome. Additionally, healthcare utilization, anxiety, depression, treatment delay, and self-efficacy are assessed at baseline and 6 months. We aim at including 245 COPD patients from 7 hospitals and 5 general practices to capture the a-priori sample size of at least 73 exacerbations per study arm.</p> <p>Discussion</p> <p>This RCT identifies if an AP is an effective component of self-management in patients with COPD and clearly differentiates from existing studies in its design, outcome measures and generalizability of the results considering that the study is carried out in multiple sites including general practices.</p> <p>Trial Registration</p> <p>NCT00879281</p

Mapping film programming across Post-War Europe (1952): Arts and media

This data paper and the data collection from which it emerges aim to present a fully harmonized data set originating in several research projects on post-war cinema programming. The paper will reflect on the collection and structure of this aggregated data set, that consists of titles of feature films screened for public viewing in cinemas in the cities Bari (Italy), Antwerp and Ghent (Belgium), Gothenburg (Sweden), Leicester (United Kingdom) and Rotterdam (Netherlands) for the year 1952. As comparisons of movie-going patterns between European countries are still rare, this paper offers a model for constructing a data set which can be replicated, scaled up and used to compare, contextualize, and eventually theorize practices of cinema-going across countries at a global level

Employing Travel Time to Compare the Value of Competing Cultural Organizations

A number of studies have applied non-market valuation techniques to measure the value of cultural goods. Virtually all of these studies are single case applications and rely mostly on stated preferences, such as contingent valuation techniques. We compare the relative value of multiple, competing goods and show how revealed preferences, in particular travel time, may be used for this. In addition, we account for heterogeneity. Using a unique transaction database with the visiting behavior of 80,821 Museum Cardholders to 108 Dutch museums, we propose a latent class application of a logit model to account for the different distances of museums to the population and for differences in willingness-to-travel.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/44648/1/10824_2005_Article_5796.pd

The importance of website content in online purchasing across different types of products

Several authors have suggested that the importance of website content elements in online purchasing varies across different types of products. Our aim is to empirically test this proposition. Here, we focus on goods versus services and hedonic versus utilitarian products. After reviewing the literature on the role of website content, we hypothesize which elements are more important for which type of product. The results of an empirical study confirm most of the different roles across different types of products. This suggests that retailers would profit from taking the differences in product types into account in designing their online stores.Goods versus services; hedonic versus utilitarian products; online purchasing; website content

Assessing the Value of Museums with a Combined Discrete Choice / Count Data Model

We develop a model for museum visits and estimate it on a large sample of holders of a museum card that provides free access to all museums. Our model distinguishes two stages, referring to the determination of the number of trips and destination choice and can deal with an effect of income on destination choice. We use a mixed logit model for destination choice and a count data model for explaining the number of trips. The model implies that welfare analyses should not only take into account the change in the logsum variables, but also changes in the number of trips. In our empirical application we find substantial local interest effects that cause a correlation between the attractiveness of a museum and its distance to the residential location of the visitor. The ranking of museums on the basis of their estimated attractiveness differs substantially from that based on the change in income that would be needed to compensate for its disappearance.museums; travel cost method; two stage budgeting
