Three major puzzles, described later in this section, have captured the attention of macroeconomic finance: the equity-premium, riskfreerate and equity-volatility puzzles. A common strand of these three asset-return puzzles is that markets are behaving as if investors fear some unknown hidden randomness that isn’t obvious from the data. People are acting in the aggregate like there is much more...

Often debates about pros and cons of various techniques for formalising lambda-calculi rely on subjective arguments, such as de Bruijn indices are hard to read for humans or nominal approaches come close to the style of reasoning employed in informal proofs. In this paper we will compare four formalisations based on de Bruijn indices and on names from the nominal logic work, thus providing some...

Pairwise comparisons between alternatives are a well-established tool to decompose decision problems into smaller and more easily tractable sub-problems. However, due to our limited rationality, the subjective preferences expressed by decision makers over pairs of alternatives can hardly ever be consistent. Therefore, several inconsistency indices have been proposed in the literature to quantif...

A microbial biofilm is structured mainly by a protective sticky matrix of extracellular polymeric substances. The appreciation of such structures is useful for the microbiologist and can be subjective to the observer. Thus, quantifying the underlying images in useful parameters by means of an objective image segmentation process helps substantially to reduce errors in quantification. This paper...

We investigate people’s attitudes towards the possible use of mobile negotiation support systems (NSS) in different social contexts and the consequences for their design. For that purpose we developed an online survey based on existing models of technology acceptance. In the questionnaire we showed five filmed scenarios of NSS use contexts. The data collected from 120 respondents, showed (a) th...

METHODS We analyzed 2009 data from the Korea Adolescent Risk Behavior Web-Based Survey, conducted on a nationally representative sample of students in grades 7 to 12. A tot...

Using perception of quality of life survey by Eurostat we construct the City Ecosystem Index (CEI) – a systemic indicator that measures subjective well-being in European cities. The purpose of the index is to inform public, policy-makers and entrepreneurs by providing a holistic view on subjective well-being across European cities. Once contrasted with the Global and Regional Systems of Entrepr...

Based on the current state of practice, this paper examines the issues in measuring disaster preparedness, and the process of constructing indicators and indices. Existing indices are examined, and a proposed framework of creating a Disaster Preparedness Index (DPi), and Resiliency Index (Ri) with a suggested list of measurement indicators is put forward. The framework and indicator list is unw...
