The role of vertical conflict in the relationship between leader self-enhancement and leader performance
No full textAlthough studies have shown that inflated self-perceptions of transformational leadership behavior negatively affect leader performance, insight into the underlying processes explaining this relationship is lacking. The current study addresses this gap by identifying vertical conflict between leaders and subordinates as one such underlying process. Using a sample of 52 leaders supervising 259 subordinates, it was found that leader self-enhancement of transformational leadership behavior is significantly and positively related to vertical conflict about both task and relationship issues. Results further indicate that vertical task conflict rather than vertical relationship conflict mediates the negative relationship between leader self-enhancement and leader performance.

Inclusionary housing in the Netherlands: breaking the institutional path?
No full textIn an international comparative perspective, the Netherlands was relatively late in introducing Inclusionary Housing (Buitelaar and De Kam in Housing Theory and Society 29(1):56–64, 2012). Referring to a conceptual framework of the institutionalisation of planning regulations, the article links this late introduction, as well as the specific content, and the actual use of inclusionary housing (IH) measures to the context of the Dutch housing and planning system. In the Netherlands, the legal ‘package’ that in 2008 explicitly introduced the powers for local authorities to require IH (both for social/affordable housing and—a unique feature of the Dutch rules—also for privately commissioned housing) was strongly tied to new rules for cost recovery. The article partly draws on a review of existing studies, of the use made of these different elements of the Dutch IH measures, but its main empirical data come from a large survey of strategic choices made by housing associations in the land market. The paper shows that local authorities do use the new legal opportunity to prescribe IH in their land-use plans, but that there is a relatively low actual use of IH requirements ‘with a bite’ in the Netherlands. This outcome reflects the level of congruence of the IH requirements with formal and informal institutions in the Dutch systems for planning and housing. The institutional design of the rules is well attuned to existing path-dependent local policies which still deliver substantial numbers of new social and affordable housing without the use of IH. In these practices, value capturing is partly internalized in the operations of housing associations that develop mixed projects of social and commercial housing. In this respect, the real test of IH measures in the Netherlands is yet to come, depending on the resilience of tried and trusted (other) practices for providing social housing
The development of trade blocs in an era of globalization
No full textThis study investigates the economic geography of international trade during the period 1950–2005. We introduce a new trade bloc variable that relies on the intramax hierarchical clustering technique to identify endogenous trade blocs with annual trade flows. Multivariate analysis with gravity-equation-based variables is used to explain how mechanisms of globalisation have affected trade patterns over the past half century. In particular, proximity and economic integration agreements are key to explaining the persistence of region-based trade blocs in a globalising world economy
For New Customers Only:A Study on the Effect of Acquisition Campaigns on a Service Company's Existing Customers' CLV
No full textThis study examines the effect of attractively priced acquisition campaigns on retention intention, and subsequently CLV, of existing customers. The main finding is that customers who are aware of the acquisition campaigns both have a significantly higher intention to stay and do actually stay longer than do customers who are unaware of these campaigns. However, since CLV is not only influenced by retention intention but also by revenues and costs, it is found that aware customers do not have a significantly different CLV than do unaware customers. The inclusion of attractiveness of the offer as an additional explanatory variable results in a positive effect of campaign attractiveness on retention intention, i.e. if the customer thinks the acquisition campaign is attractive, the retention intention will be higher. However, the effect that is found for intention cannot be directly translated in actual behavior. (C) 2014 Direct Marketing Educational Foundation, Inc., dba Marketing EDGE.</p
Control of Surface Wettability Using Tripodal Light-Activated Molecular Motors
No full textMonolayers of fluorinated light-driven molecular motors were synthesized and immobilized on gold films in an altitudinal orientation via tripodal stators. In this design the fimctionalized molecular motors are not interfering and preserve their rotary function on gold. The wettability of the self-assembled monolayers can be modulated by UV irradiation.</p
Herbivore-mediated structural diversity of vegetation
No full textGrote herbivoren kunnen een positieve invloed hebben op structurele diversiteit in de vegetatie, maar doen dit niet altijd. Het doel van dit proefschrift is om kennis te vergaren over de voorwaarden waaronder grote herbivoren een positieve invloed hebben op structurele diversiteit. Hiervoor combineerde ik modelstudies met beschrijvend en experimenteel veldonderzoek. De resultaten toonden dat abiotische heterogeniteit in grote mate voorspelt of herbivoren succesvol grasland-ruigte mozaïeken creëren. Daarnaast ontdekte ik dat grasland en ruigte patches in deze mozaïeken ongesynchroniseerde successie vertonen , omdat in ruigte er een grotere kans is op verjonging van houtige gewassen. Bovendien is plantensoortenrijkdom op kleine ruimtelijke schaal hoger in grasland-ruigte mozaïeken in vergelijking met onbeweide locaties. Bij grotere ruimtelijke schaal hangt het af van de onderliggende abiotische heterogeniteit of beweiding een positief effect heeft op plantensoortenrijkdom. Vervolgens onderzocht ik verjonging van houtige gewassen in de Oostvaardersplassen (OVP), waar de herbivoorgemeenschap volledig bottom-up gereguleerd is. De resultaten toonden dat verjonging van houtige gewassen in de OVP sterk wordt beperkt door herbivoren. Echter, fluctuerende herbivoordichtheden in tijd of ruimte hebben waarschijnlijk juist een positief effect op de verjonging van houtige gewassen in de OVP. Deze fluctuaties van herbivoordichtheid in de tijd kunnen worden gegenereerd door de interactie tussen herbivoren van verschillende lichaamsgrootte en predatoren van verschillende lichaamsgrootte. De bevindingen van dit proefschrift kunnen bijdragen aan succesvolle ontwikkelingen van ecosystemen met een hoge structurele diversiteit in de vegetatie die van grote ecologische en sociaaleconomische waarde zijn
Bacterial mass transport and adhesion using macroscopic fluorescense imaging
No full textMeer inzicht in transport bacteriën In dit onderzoek, is er gekeken naar de effectiviteit van eerder gepubliceerde operon predictiemethodes en zijn er nieuwe methodes hiervoor ontwikkeld. Van de 29 gepubliceerde operon predictiemethoden waren er vier vrijelijk beschikbaar. Uit deze methoden is een lijst van vaak gebruikte indicatoren van operonen gedestilleerd en met deze lijst hebben we eigen operon predictiemethoden ontwikkeld. Deze methoden zijn gebaseerd op een minimale set van indicatoren die zijn gecombineerd met verschillende machine learning algorithmen
