The expansion of higher education raises the risk environment for school-leavers as more occupations become partially graduate with the result that occupational signals are fuzzy. This makes the educational decision more difficult and more risky, especially with more of the cost of higher education being transferred to the individual. After a discussion of the nature of risk, derived from Beck,...

The increasing consideration of behavioral aspects in operations management models has prompted greater use of choice-based conjoint (CBC) studies in operations research. Such studies can elicit consumers’ willingness ...

A new extraclion system has been designed and constructed which allows the extraction of gases from air bubbles in ice without melting it. The ice sample of abollt 500 g is crushed in an evacuated container by a milling cutter, and the gas escaping from the opened bubbles is collected by condensation at 15 K. Results of CO 2 analyses of extracted gases a re discussed with respcCI to possible co...

An adaption of the original HLL scheme for the one-dimensional nonconservative Euler system modeling gaz flow in variational porosity media is proposed . Numerical scheme is detailed and algorithm is tested with two Riemann problems.

Do people from different countries and different backgrounds have similar preferences for how much more the rich should earn than the poor? Using survey data from 40 countries (N = 55,238), we compare respondents' estimates of the wages of people in different occupations-chief executive officers, cabinet ministers, and unskilled workers-to their ideals for what those wages should be. We show th...
