Search for prompt neutrinos with AMANDA-II

A search for prompt neutrinos is performed with an analysis of the atmospheric neutrino data recorded by the AMANDA-II detector at the geographical South Pole in the years 2000-2003. The spectrum is reconstructed and limits on prompt production models spectrum are set according to our measurements.

Ringier (Familie)

Famille de pasteurs, politiciens et entrepreneurs de Zofingue, attestée pour la première fois en 1527, lorsque leur aïeul Jean, tonnelier originaire de Nîmes, obtint la bourgeoisie de Zofingue. Michael (1521-1605), avoyer, l'un de ses cinq fils, est l'ancêtre de la branche des imprimeurs et éditeurs. Après lui, de nombreux R. consolidèrent durablement l'influence de la famille. A partir du XVIIIe s., divers membres firent des carrières politiques, tels Samuel (1706-1786), avoyer, et Rudolf Friedrich (1805-1886), président de la ville. Les R. furent aussi très liés à l'Eglise. Le fils de Michael, Moritz (1557-1615), fut pasteur et doyen à Zofingue. Jusqu'au XIXe s., la famille compta une trentaine d'ecclésiastiques, essentiellement des pasteurs officiant sur le territoire bernois, tels Johann Heinrich ( -> 3) et Michael ( -> 8). Les conseillers Beat (1712-1778) et Niklaus (1734-1766) furent les premiers R. actifs dans la production protoindustrielle de drap. D'autres négociants suivirent jusqu'au milieu du XIXe s. L'architecte Niklaus Emanuel (1744-1815) construisit l'hôtel de ville de Zofingue (1792-1795) de style baroque tardif. Johann Rudolf ( -> 4) se distingua sous la République helvétique (1798-1803). Samuel (1767-1826), conseiller municipal de Zofingue, créa les armoiries du canton d'Argovie en 1803. Les R. s'affirmèrent sur le plan cantonal avec Karl Ludwig ( -> 6), chancelier, et Arnold ( -> 1), conseiller d'Etat et plusieurs fois landamman, et sur le plan fédéral avec Johann Rudolf ( -> 5), conseiller national, et Gottlieb ( -> 2), conseiller aux Etats et chancelier de la Confédération. Johann Rudolf (1803-1874) fonda, en 1833, l'imprimerie Ringier à Zofingue, reprise par son fils Franz Emil (1837-1898). A partir de 1898, Paul August ( -> 9), représentant de la troisième génération d'imprimeurs, agrandit l'entreprise dont il fit la principale imprimerie et maison d'édition de Suisse. Cette expansion se poursuivit après 1960 sous son fils Hans (1906-2003). Avec les fils de celui-ci, Christoph (naissance1941, dans la firme jusqu'en 1991) et Michael (naissance1949), Ringier devint, à partir de 1985, une entreprise multinationale et multimédia.

ON THE EFFECT OF VIRTUAL REALITY ON STUDENT UNDERSTANDING OF AND INTEREST IN PHYSICS

This study investigated the effect that the video game Portal 2 had on students understanding of Newton’s Laws and their attitudes towards learning science during a two-week afterschool program at a science museum. Using a pre/posttest and survey design, along with instructor observations, the results showed a statistically relevant increase in understanding of Newton’s Laws (p=.02<.05) but did not measure a relevant change in attitude scores. The data and observations suggest that future research should pay attention to non-educational aspects of video games, be careful about the amount of time students spend in the game, and encourage positive relationships with game developers.

Atmospheric CO₂, δ(O₂/N₂) and δ13CO2 measurements at Jungfraujoch, Switzerland: results from a flask sampling intercomparison program

We present results from an intercomparison program of CO2, δ(O2/N2) and δ13CO2 measurements from atmospheric flask samples. Flask samples are collected on a bi-weekly basis at the High Altitude Research Station Jungfraujoch in Switzerland for three European laboratories: the University of Bern, Switzerland, the University of Groningen, the Netherlands and the Max Planck Institute for Biogeochemistry in Jena, Germany. Almost 4 years of measurements of CO2, δ(O2/N2) and δ13CO2 are compared in this paper to assess the measurement compatibility of the three laboratories. While the average difference for the CO2 measurements between the laboratories in Bern and Jena meets the required compatibility goal as defined by the World Meteorological Organization, the standard deviation of the average differences between all laboratories is not within the required goal. However, the obtained annual trend and seasonalities are the same within their estimated uncertainties. For δ(O2/N2) significant differences are observed between the three laboratories. The comparison for δ13CO2 yields the least compatible results and the required goals are not met between the three laboratories. Our study shows the importance of regular intercomparison exercises to identify potential biases between laboratories and the need to improve the quality of atmospheric measurements.

Cognitive dysfunction in children with brain tumors at diagnosis

Background: Survivors of brain tumors have a high risk for a wide range of cognitive problems. These dysfunctions are caused by the lesion itself and its surgical removal, as well as subsequent treatments (chemo- and/or radiation therapy). Multiple recent studies have indicated that children with brain tumors (BT) might already exhibit cognitive problems at diagnosis, i.e., before the start of any medical treatment. The aim of the present study was to investigate the baseline neuropsychological profile in children with BT compared to children with an oncological diagnosis not involving the central nervous system (CNS). Methods: Twenty children with BT and 27 children with an oncological disease without involvement of the CNS (age range: 6.1 to 16.9 years) were evaluated with an extensive battery of neuropsychological tests tailored to the patient’s age. Furthermore, the child and his/her parent(s) completed self-report questionnaires about emotional functioning and quality of life. In both groups, tests were administered before any therapeutic intervention such as surgery, chemotherapy or irradiation. Groups were comparable with regard to age, gender and socioeconomic status. Results: Compared to the control group, patients with BTs performed significantly worse in tests of working memory, verbal memory and attention (effect sizes between 0.28 and 0.47). In contrast, the areas of perceptual reasoning, processing speed and verbal comprehension were preserved at the time of measurement. Conclusion: Our results highlight the need for cognitive interventions early in the treatment process in order to minimize or prevent academic difficulties as patients return to school.
