När vi jämför människan med andra djur, letar vi gärna efter särdrag som gör henne unik. Hur Homo blev sapiens lyfter fram människans alldeles speciella förmåga att tänka och att skaffa sig kunskap om världen. Under människans långa utveckling blir tänkandet gradvis alltmer avancerat. Gärdenfors vägleder oss genom hjärnans och tankeförmågornas vindlande tillblivelse, och visar hur människans inre

Innovations should create value for increasingly individualistic consumers with varying demands and for other stakeholders. Today, retailers have the power in the supply/value chain. This research investigates how Swedish food retailers view innovations, their role and that of customers and suppliers in the development process, and how they see future development. The study is based on open-ended

Increasing noise regulations at urban airports force jet engine manufactures to develop and build more quiet engines. Over recent years, a significant reduction in fan and mechanical noise has been achieved. However, the jet exhaust is the principal source of noise. The acoustical field that is generated by a turboengine jet exhaust running near the ground level is considered. The full equations o

Att utöva ledarskap är ofta svårt. Inte sällan krackelerar eller kull­kastas försök att leva upp till tjusiga ledarskapsideal. Boken skildrar ledarskapsförsök i praktiken och den bökiga verklig­heten snarare än ledarskapsfantasier i en perfekt värld. Även om chefer gärna vill se sig som ledare med ambitioner att åstadkomma allt möjligt strategiskt och visionärt så är medarbetare inte alltid lyhörd

This paper describes the design, simulation and measurement of a GaN power amplifier suitable for envelope and phase signal combination. The low-frequency envelope signal is used to vary the gate (bias) voltage of the device, resulting in a pulse width modulated drain voltage, while modulation of supply voltage or current is avoided. The test circuit is implemented using a discrete GaN HEMT power

Malmö stad antog 1997 en ny personalpolicy, P2006, vilken är indelad i sju profilområden. Ett av dessa profilområden har som målsättning att utveckla flexibla arbetstidsmodeller som ska tillgodose verksamhetens, kundens och den anställdes önskemål, samt skapa förutsättningar för alternativa karriärvägar för personalen. I samband med en utvärdering av de flexibla arbetstidsmodellerna uppdrogs åt S

Organizations have boundaries that serve various purposes; for example, differentiating internal operations from external activities and controlling flows of information. Boundaries can however hinder knowledge exchange in inter‐organizational collaboration, leading to less effective outcomes. Empirical results from comparative case studies on how boundaries between organizations in a project can

With a worldwide increase in disasters, the effects of climate change are already being felt, and it is the urban poor in developing countries that are most at risk. There is an urgent need to better understand the factors that determine people’s capacity to cope with and adapt to adverse climate conditions. This paper examines the influence of formal education in determining the adaptive capacity

We observe and analyze a considerable enhancement of photoelectron intensity of the valence band features in solid B2O3 upon tuning the photon energy across the B 1s → π*2pz resonance. This enhancement is an evidence of the strong 2p electron correlations in pre-edge photoionization dynamics in boron oxide. Such strength of the correlation is unusual for a solid, whose valence band is composed of
