Systems Analysis to Promote Frames and Mental Models for Sustainable Water Management

In the water sector, there have been numerous failures in projects aiming at sustainable development and there have been some, but less numerous, examples of successes. However, the most striking observation is the near universal failure to learn from these examples. Somehow, scientists and decision makers have allowed the indications of new approaches and opportunities go undetected because they

How do scientists develop and use scientific software?

New knowledge in science and engineering relies increasingly on results produced by scientific software. Therefore, knowing how scientists develop and use software in their research is critical to assessing the necessity for improving current development practices and to making decisions about the future allocation of resources. To that end, this paper presents the results of a survey conducted on

När kvinnor och män får barn : Ett psykologiskt och könsspecifikt betraktande av psykisk hälsa och ohälsa

Popular Abstract in Swedish Avhandlingens huvudsakliga syfte är att öka kunskapen om kvinnors och mäns psykiska hälsa och välbefinnande i samband med att de väntar eller just har fått ett barn, och detta utifrån aspekter som är relevanta för mödra- och barnhälsovårdens insatser: Kunskap - erhåller kvin-nor och män för dem adekvata kunskaper när de står inför att bli föräldrar för första gången? StThe central issue is to increase knowledge of women's and men's mental wellbeing when their child is about to be born, as seen from four aspects relevant to maternity and child health care centres. Major psychological theories are the attachment theory and the affect theory, health psychology with theories on nervous tension, vulnerability, coping and individual resources, clinical psychology to u

Accuracy of the Hartree-Fock and Local Density Approximations for Electron Densities: A study for Light Atoms

We compare the electron densities and Hartree potentials in the local density and the Hartree-Fock approximations to the corresponding quantities obtained from more accurate correlated wavefunctions. The comparison is made for a number of two-electron atoms, Li, and for Be. The Hartree-Fock approximation is more accurate than the local density approximation within the 1s shell and for the spin pol

Digitizing Intangible Cultural Heritage

As part of the UNESCO project "Establishment of a National Inventory and Electronic Database of Lithuanian Intangible Cultural Heritage" the authors, representing the EU-funded project "European Cultural Heritage Online" (ECHO) were invited to give a course in digital archiving called "Digitizing Intangible Cultural Heritage" in Vilnius, Lithuania, March 15 to 20, 2004. The present report summariz

A 5GHz 90-nm CMOS all digital phase-locked loop

An all digital phase-locked loop (ADPLL) has been implemented in a 90-nm CMOS process. It uses a phase frequency detector (PFD) connected to two time-to-digital converters (TDC). To save power the TDCs use uneven delay time in the delay line cells. An automatic tuning bank controller selects active bank of the digitally controlled oscillator (DCO), which features three separate tuning banks. The P

Authorial voice and the addressee in Pausanias' Periegesis

Pausanias’ Hellados Periegesis has proven to be difficult to group with other ancient works, whether preserved or not. In light of its highly varied subject matter, it is tempting to sort Pausanias together with other authors of miscellanies from the second century AD, like Aelian and Athenaeus. Like the Deipnosophistae and the Varia historia among other works, the Periegesis is a collection of fa

Diffusion of the Balanced Scorecard in the Swedish Municipality Sector

This article examines the introduction of the Balanced Scorecard (BSC) among municipalities in Sweden from a diffusion perspective. The point of departure in the article is that there is a gap in our understanding concerning the diffusion of new management accounting constructs. Over the last decade, research has largely been based on empirical evidence regarding early adopters. Furthermore, these

Introductory Study of Variable Valve Actuation for Pneumatic Hybridization

Urban traffic involves frequent acceleration and deceleration. During deceleration, the energy previously used to accelerate the vehicle is mainly wasted on heat generated by the friction brakes. If this energy that is wasted in traditional IC engines could be saved, the fuel economy would improve. One solution to this is a pneumatic hybrid using variable valve timing to compress air during decele
