Chapter 4: Between consolidation and innovation: The international criminal court's trial chamber judgment in the lubanga case
The judgment delivered by Trial Chamber I of the International Criminal Court on 14 March 2012 in the case of The Prosecutor v. Thomas Lubanga Dyilo was welcomed by a number of experts as a landmark decision. Not only was the judgment the first ever adopted by the Court, thus marking a new step in the operationalization of the Rome Statute, but it also provided an opportunity for addressing a number of procedural and substantive issues that are essential to the progressive development of both international criminal and humanitarian law. This chapter does not seek to provide a comprehensive analysis of all these issues. It focuses instead on the core of the judgment, i.e., the definitions of the war crimes for which Thomas Lubanga Dyilo was convicted (Sect. 4.3). The Trial Chamber found that the accused was guilty of conscripting and enlisting children under 15 into an armed group, namely the Forces Patriotiques Pour la Libération du Congo (UPC/FPLC), and of using them to participate actively in hostilities. These crimes occurred in the Ituri region of the Democratic Republic of the Congo from September 2002 to August 2003. This article also examines how the Trial Chamber addressed the preliminary question of the characterization of the situation during the relevant period (Sect. 4.2). The judgment provides essential insight into the Trial Chamber's understanding of the notion of armed conflict within the framework of the Rome Statute. Copyright © T.M.C.

La formation des enseignants primaires genevois
La formation universitaire des instituteurs genevois s’est historiquement constituée à la fois en référence aux sciences de l’éducation et en lien avec les attentes politico-administratives de l’institution scolaire. Multiréférentiels, les savoirs professionnels qu’elle propose échappent à la production pure et simple de pratiques instrumentalisées. Sur cette base, nous questionnons les transactions autour de la formation en termes de tension dialectique, à l’heure où le pilotage externe du système éducatif se met en place en Suisse romande et à Genève.Genevan primary school teachers’ university training has historically built up both with reference to educational sciences and linked with the political and administrative expectations of the school institutions. The professional knowledge it proposes is multi-referential and escapes the mere production of instrumentalized practices. On this basis, dealings around training in terms of dialectical tension are questioned, at a time when the external management of the educational system is being set up in French-speaking Switzerland and in Geneva.Historisch beruft sich die universitäre Ausbildung der Grundschullehrer auf die Erziehungswissenschaft und hat zugleich eine Verbindung mit den politisch-administrativen Erwartungen der Schulinstitution. Die multireferentiellen Berufskenntnisse, die sie vorschlägt, entgehen der puren Produktion von instrumentalisierten Tätigkeiten. Infolgedessen studieren wir die Transaktionen um die Ausbildung herum aus der Perspektive der dialektischen Spannung, in einer Zeit, wo die externe Steuerung des Bildungssystems in der französischen Schweiz und in Genf eingeführt wird.La formación universitaria de los maestros ginebrinos históricamente se ha constituido à la vez en referencia a las ciencias de la educación y en relación con las expectativas político-administrativas de la institución escolar.

Stem emissions of monoterpenes, acetaldehyde, and methanol from Scots pine (Pinus sylvestris L.) affected by tree water relations and cambial growth
Abstract Tree stems are an overlooked source of volatile organic compounds (VOCs). Their contribution to ecosystem processes and total VOC fluxes is not well studied, and assessing it requires better understanding of stem emission dynamics and their driving processes. To gain more mechanistic insight into stem emission patterns, we measured monoterpene, methanol, and acetaldehyde emissions from the stems of mature Scots pines (Pinus sylvestris L.) in a boreal forest over three summers. We analysed the effects of temperature, soil water content, tree water status, transpiration, and growth on the VOC emissions, and used generalized linear models to test their relative importance in explaining the emissions. We show that Scots pine stems are considerable sources of monoterpenes, methanol, and acetaldehyde, and their emissions are strongly regulated by temperature. However, even small changes in water availability affected the emission potentials: increased soil water content increased the monoterpene emissions within a day, whereas acetaldehyde and methanol emissions responded within two to four days. This lag corresponded to their transport time in the xylem sap from the roots to the stem. Moreover, the emissions of monoterpenes, methanol, and acetaldehyde were influenced by the cambial growth rate of the stem with six- to ten-day lags. This article is protected by copyright.

Protons in near earth orbit
The proton spectrum in the kinetic energy range 0.1 to 200 GeV was measured
by the Alpha Magnetic Spectrometer (AMS) during space shuttle flight STS-91 at
an altitude of 380 km. Above the geomagnetic cutoff the observed spectrum is
parameterized by a power law. Below the geomagnetic cutoff a substantial second
spectrum was observed concentrated at equatorial latitudes with a flux ~ 70
m^-2 sec^-1 sr^-1. Most of these second spectrum protons follow a complicated
trajectory and originate from a restricted geographic region.Comment: 19 pages, Latex, 7 .eps figure
Search for antihelium in cosmic rays
The Alpha Magnetic Spectrometer (AMS) was flown on the space shuttle
Discovery during flight STS-91 in a 51.7 degree orbit at altitudes between 320
and 390 km. A total of 2.86 * 10^6 helium nuclei were observed in the rigidity
range 1 to 140 GV. No antihelium nuclei were detected at any rigidity. An upper
limit on the flux ratio of antihelium to helium of < 1.1 * 10^-6 is obtained.Comment: 18 pages, Latex, 9 .eps figure
A Study of Cosmic Ray Secondaries Induced by the Mir Space Station Using AMS-01
The Alpha Magnetic Spectrometer (AMS-02) is a high energy particle physics
experiment that will study cosmic rays in the to range and will be installed on the International Space Station
(ISS) for at least 3 years. A first version of AMS-02, AMS-01, flew aboard the
space shuttle \emph{Discovery} from June 2 to June 12, 1998, and collected
cosmic ray triggers. Part of the \emph{Mir} space station was within the
AMS-01 field of view during the four day \emph{Mir} docking phase of this
flight. We have reconstructed an image of this part of the \emph{Mir} space
station using secondary and emissions from primary cosmic rays
interacting with \emph{Mir}. This is the first time this reconstruction was
performed in AMS-01, and it is important for understanding potential
backgrounds during the 3 year AMS-02 mission.Comment: To be submitted to NIM B Added material requested by referee. Minor

Isotopic Composition of Light Nuclei in Cosmic Rays: Results from AMS-01
The variety of isotopes in cosmic rays allows us to study different aspects
of the processes that cosmic rays undergo between the time they are produced
and the time of their arrival in the heliosphere. In this paper we present
measurements of the isotopic ratios 2H/4He, 3He/4He, 6Li/7Li, 7Be/(9Be+10Be)
and 10B/11B in the range 0.2-1.4 GeV of kinetic energy per nucleon. The
measurements are based on the data collected by the Alpha Magnetic
Spectrometer, AMS-01, during the STS-91 flight in 1998 June.Comment: To appear in ApJ. 12 pages, 11 figures, 6 table
