De Graaf, R. (author), Van der Duin, P.M. (author)Since many of today's problems are becoming ever more complex, the way we look for and manage innovations to solve these problems should also be innovated. We introduce the ‘Collective Innovation’ approach to deal with these kind of ‘wicked problems’ that require the input of many different parties. Furthermore, in Collective Innovation it is...journal article 2013

Kleinknecht, A.H. (author), Naastepad, C.W.M. (author), Storm, S.T.H. (author)Versoepeling van het ontslagrecht past goed bij kostenbeheersing en loonmatiging. Maar worden bedrijven er ook slimmer van? Nee, laten Alfred Kleinknecht, Ro Naastepad en Servaas Storm zien. Flexibele arbeidsverhoudingen beïnvloeden innovatie en productiviteitsgroei negatief, vooral ook omdat kennismanagement bij kortere dienstverbanden...journal article 2012

Van Geenhuizen, M.S. (author), Nijkamp, P. (author)Smart high-tech companies are characterized by knowledge intensity and open innovation. Even when these companies emerge in spatial clusters or dense urban places, they may utilize knowledge networks on a global scale. However, there is not much insight into the factors that shape knowledge networks, the role of virtualization herein and the...journal article 2011

Alpay, L.L. (author), Blanson Henkemans, O. (author), Otten, W. (author), Rövekamp, T.A.J.M. (author), Dumay, A.C.M. (author)Objective: E-health may enable the empowerment process for patients, particularly the chronically ill. However, e-health is not always designed with the requirements of patient empowerment in mind. Drawing on evidence-based e-health studies, we propose directions for best practices to develop e-health that promotes patient empowerment. Methods:...journal article 2010

Blank, J.L.T. (author), Valdmanis, V.G. (author)This paper describes the efficiency of Dutch hospitals using the method of Data Envelopment Analysis (DEA). In particular the analysis focuses on explaining cost inefficiency measures due to each hospital’s operating environment. In previous works, the resulting DEA score is regressed on environmental factors via a Tobit approach. Previously,...journal article 2010

Blank, J.L.T. (author), Van Hulst, B.L. (author)This paper describes the efficiency of Dutch hospitals using the Data Envelopment Analysis (DEA) method with bootstrapping. In particular, the analysis focuses on accounting for cost inefficiency measures on the part of hospital corporate governance. We use bootstrap techniques, as introduced by Simar and Wilson (J. Econom. 136(1):31–64, 2007),...journal article 2010

Van Beers, C. (author), Van der Panne, G. (author)This study examines the impact of external and internal scale economies on the decision to start exporting and the level of exports of innovating firms. Based on new trade theory, increasing returns to scale—both internal and external scale economies—are considered an important source of comparative and competitive advantage. The empirical...journal article 2009

Van Geenhuizen, M.S. (author), Soetanto, D.P. (author)Support to enhance early growth of academic spin-off firms is at the core of many economic policies. Efficiency of this support has been recently questioned due to slow growth of spinoff firms in various European countries. However, despite many studies to improve support, there is virtually no empirical insight into resistance of obstacles that...journal article 2009

Van Beers, C. (author), Berghäll, E. (author), Poot, T. (author)This paper investigates domestic and foreign innovating firms’ determinants of R&D collaboration with domestic universities and public knowledge institutes in Finland and the Netherlands. We put particular emphasis on the impact of incoming academic spillovers on the probability to co-operate with these public R&D institutes. Based on data from...journal article 2009

Van Geenhuizen, M. (author), Nijkamp, P. (author)In the development of modern urban systems, we are facing a shift from central cities as the major location of coordination functions, high-order services and innovative activities, to interconnected nodes at some distance in a larger metropolitan area. However, which cities in the emerging new spatial constellation qualify to become such a node...journal article 2009

Blank, J.L.T. (author)In many public service industries, firms are constrained by a cost (budget) and characterized by non-maximizing output behavior, due to bureaucratic behavior, for instance. This paper proposes a model based on the assumption that firms with a cost constraint do not maximize service levels due to resource preferences. It derives the exact...journal article 2008

Hartmann, L. (author)Door handig gebruik te maken van kooldioxide onder hoge druk kan het voor de fijnchemische industrie veel interessanter worden om gebruik te maken van een bijzondere klasse milieuvriendelijke oplosmiddelen: ‘ionische vloeistoffen’. Onderzoekster dr.ir. Maaike Kroon liet zien dat de besparingen, in elk geval op papier, astronomisch zijn.journal article 2007

Andriessen, J.H.E. (author)Many modern knowledge intensive organisations rely on knowledge sharing communities, often called ‘communities of practice. These communities can be found in many organisations, but their forms and functions appear to be quite diverse. This implies that questions concerning the functioning of communities, (how do they work) and questions...journal article 2006

Andriessen, J.H.E. (author)Sharing knowledge is an important aspect of most modern organisation. Ideas about how to stimulate knowledge sharing abound, but without much theorising. The objective of this article is to link basic motivation theories to empirical studies of knowledge sharing and its conditions. The paper starts with an orientation on company strategies to...journal article 2006

Hartmann, L. (author)Huishoudelijk afval bevat veel koper, aluminium, nikkel, zink en zilver. Tot nu toe kan daarvan ongeveer 20% worden teruggewonnen, en jaarlijks verdwijnt voor 45 miljoen euro aan koper en aluminium de grond in. Nieuwe Delftse technologie en Amsterdamse innovatie scheiden bodemas in waardevolle non-ferro metalen en schone bouwstoffen.journal article 2006

Hartmann, L. (author)Aan een systeem in evenwicht waarop slechts twee krachten werken, zoals een schommel, is vrij eenvoudig te zien of het stabiel is. Bij drie krachten in evenwicht, zoals bijvoorbeeld een hangmat, was dat tot nu toe niet mogelijk. Een team van werktuigbouwkundig ingenieurs aan de TU Delft ontdekte een wiskundige methode om de stabiliteit te...journal article 2005

Hartmann, L. (author)In Nederland wordt jaarlijks 25 miljoen m3 minerale slib uit rivieren, kanalen en havens gebaggerd, waarvan zo'n twintig procent is verontreinigd. Het niet-vervuilde slib wordt meestal voor de kust gestort. De overige vijf miljoen m3 mag alleen maar op bepaalde, daartoe aangewezen plaatsen worden gedumpt, tegen een fors bedrag per kuub.journal article 2003
