This paper examines how social relations and norms contribute to the emergence of generalized trust in economic action. Our core proposition is that the more positive the local social exchange relationship, the greater an actor’s propensity to place trust in strangers. Our research design integrates behavioral measures elicited by incentivized experimental trust games with survey data using a rand

The blade tip region encounters high thermal loads because of the hot gas leakage flows, and it must therefore be cooled to ensure a long durability and safe operation. A common way to cool a blade tip is to design serpentine passages with 180-deg turn under the blade tip-cap inside the turbine blade. Improved internal convective cooling is therefore required to increase the blade tip lifetime. Di

This paper presents a hardware mapping of an auto-correlator for Orthogonal Frequency Division Multiplexing stage for three radio standards: LTE, DVB-H, and IEEE 802.11n. Hardware cost is minimized by using only the sign bit in the autocorrelation function. The frequency offset estimation procedure is dramatically simplified by reducing the phase of the envelope to pi/2 resolution, which in turn r

Combustion phasing in a Homogeneous Charge Compression Ignition (HCCI) engine can be achieved by affecting the time history of pressure and temperature in the cylinder. The most common way has been to control the inlet air temperature and thereby the temperature in the cylinder at the end of the compression stroke. However this is a slow parameter to control, especially cycle to cycle. A multi- cy

This article deals with depictions of humans during the Vendel and Viking Age. While in earlier research, the iconographic approach has been predominant, the point of departure here are the functions pictures may have had in oral societies. As a new approach, the method of context analysis is presented. The main question is how depictions have been used differently by different social groups. In t

The forward to this collection of texts about the use of new media for protest politics by social movements aims to set the intellectual stage for the chapter that follow. In particular the socio-cultural origins as well as limitations of the internet in these civic contests are highlighted

Fuel cells are promising for future energy systems, since they are energy efficient and, when hydrogen is used as fuel, there are no emissions of greenhouse gases. Fuel cells have during recent years various improvements, however the technology is still in the early phases of development, this can be noted by the lack of dominant design both for singe fuel cells, stacks and for entire fuel cell sy

I kapitlet beskrivs grundläggande begrepp inom behaviouristisk inlärningsteori och kognitiv personlighetsteori. Fokus läggs på de teorier som haft störst praktisk betydelse genom att de ligger till grund för olika former av kognitiv terapi och beteendeterapi. Till de begrepp som behandlas hör: respondent och operant beteende, positiv och negativ förstärkning, modellinlärning, automatiska tankar, k
