    Individual Selection for Cooperative Group Formation

    No full text
    It is well known that certain environmental conditions, such as a spatially structured population, can promote the evolution of cooperative traits. However, such conditions are usually assumed to be externally imposed. In this paper, we present a model that allows the conditions that promote or hinder cooperation to arise adaptively via individual selection. Consequently, instead of selection simply favouring cooperation under imposed environmental conditions, in our model selection also operates on the conditions themselves via a niche construction process. Results are presented that show that the conditions that favour cooperation can evolve, even though those that favour selfish behaviour are also available and are initially selected for

    Bouwlogistieke innovaties weerbarstig te implementeren

    Toelevering van bouwmaterialen aan bouwprojecten is complex en verregaande gesegregeerd. De bouwsector staat voor een kans te innoveren op het vlak van de bouwlogistiek. In het verleden is ervaring opgedaan met ‘best-practices’ die voldoende kansen bieden de noodzakelijk innovatie door te voeren. Via proeftuinen wordt in het TKI-project ‘4C in Bouwlogistiek’ gewerkt aan het implementeren van de ‘best-practices’: bouwlogistiek hubs, bouwtickets, vandaag voor morgen, opstelstrips en mobiele voorraadcontainers. Ervaring leert dat cultuurverschillen tussen bouwkundigen en logistici, en gebrek aan meten en vastleggen van gegevens de implementatie bemoeilijken. Echte innovatie gaat mogelijk komen van bedrijven die logistiek geheel anders gaan doen. Voorbeelden van concepten die voor innovatie in bouwlogistiek kunnen zorgen zijn te vinden bij: IKEA, Toyota, Zara, Uber. Ook 3Dprinting gaat de bouwlogistiek sterk beïnvloeden.Engineering, Systems and ServicesTechnology, Policy and Managemen

    Delegated Portfolio Management

    No full text
    In this paper, we examine optimal portfolio decisions within a decentralized framework. There are many portfolio managers choosing optimal portfolio weights in a mean-variance framework and taking decisions in a decentralized way. However, the overall portfolio may not be efficient, as the portfolio managers do not take into account the overall covariance matrix. We show that the initial endowment that portfolio managers can use within the firm in order to manage their portfolios can be used as a control variable by the top administration and redistributed within the firm in order to achieve overall efficiency.

    Moral Dimensions of Humour : Essays on Humans, Heroes and Monsters

    No full text
    Tässä teoksessa tarkastellaan huumorin käsitettä ja sen suhdetta ihmisen käyttäytymiseen. Kirjan luvut kattavat laajan ajanjakson ulottuen 1500-luvulta nykypäivään. Niissä syvennytään erilaisiin kulttuurisiin konteksteihin, sosiaalisten normien rajoihin ja kannustetaan lukijoita pohtimaan huumorin eettisiä vaikutuksia. Teos tuo esiin lukuisia esimerkkejä sankareista ja hirviöistä, jotka toimivat vertauskuvina inhimillisyyden moraaliselle kirjolle. Nämä vertauskuvat, joita löytyy niin digitaalisen kulttuurin tuotteista, kansanperinteestä, viihdeteknologiasta kuin politiikasta, edustavat sekä tavoiteltavia ihanteita että ihmisyyden synkempiä puolia.This volume explores the concept of humour and its relationship with human behaviour. The interdisciplinary essays in this book cover a wide range of time, from the sixteenth century to the present day. They delve into various cultural contexts, challenging social norms and prompting readers to reflect on the ethical implications of humour. The collection highlights the varied metaphors of heroes and monsters in each case study, which are crucial to understanding the moral spectrum of human existence. These metaphors represent aspirational ideals and darker aspects of what it means to be human. The book encourages readers to critically analyse the complexity of humorous objects and social practices in contexts like digital culture, mythical folklore, entertainment technology, or politics, recognising their interconnectedness with societal issues and emphasising that different settings might call for different interpretations.
