Study of doubly strange systems using stored antiprotons

Bound nuclear systems with two units of strangeness are still poorly known despite their importance for many strong interaction phenomena. Stored antiprotons beams in the GeV range represent an unparalleled factory for various hyperon-antihyperon pairs. Their outstanding large production probability in antiproton collisions will open the floodgates for a series of new studies of systems which contain two or even more units of strangeness at the P‾ANDA experiment at FAIR. For the first time, high resolution γ-spectroscopy of doubly strange ΛΛ-hypernuclei will be performed, thus complementing measurements of ground state decays of ΛΛ-hypernuclei at J-PARC or possible decays of particle unstable hypernuclei in heavy ion reactions. High resolution spectroscopy of multistrange Ξ−-atoms will be feasible and even the production of Ω−-atoms will be within reach. The latter might open the door to the |S|=3 world in strangeness nuclear physics, by the study of the hadronic Ω−-nucleus interaction. For the first time it will be possible to study the behavior of Ξ‾+ in nuclear systems under well controlled conditions

Children First? Changing Attitudes Toward the Primacy of Children in Five European Countries

Parenting support is a new policy field, directed toward teaching parents how to assume their role. Its foundations are embedded in a child-centered social investment approach, which is becoming dominant in Western European welfare states. This article aims at exploring the extent to which ideas underlying these policies are coherent with individual attitudes toward children, parents, their relationship and their change over time. We analyze how these attitudes changed in five selected countries (France, Germany, the Netherlands, the United Kingdom, and Sweden), using data from all four waves of the European Values Study (1981, 1990, 1999, 2008). We also test what kind of values are behind these attitudes, employing logistic regression as method. Our main finding is that there has been a value shift in public sentiments regarding the primacy of children, which is no longer to be viewed as a traditional type of attitude
