    "The Division of Jurisdiction Over Concentrations in the EEC"

    Get PDF
    [From the Introduction]. The EEC Merger Control Regulation divides jurisdiction over concentrations in a fashion that may appear straight forward but is actually quite complex. The basic outline is clear: concentrations that have a "Community dimension" fall within the Commission's jurisdiction, whereas those that lack a "Community dimension" do not. For the moment the "Community dimension" is measured by a three-part test: (1) Each of at least two undertakings must have an "aggregate worldwide turnover" exceeding ECU 5 billion;(2) each must have an "aggregate Community-wide turnover" of ECU 250 million; and (3) at least one of the undertakings must achieve more than one-third of its aggregate Community-wide turnover outside of a single EC member state. The Commission would have preferred lower thresholds (of ECU 2 billion and 100 million), respectively), and may get them when the matter is reviewed by the Council in 1993

    Capitate and hamate fracture in a child: the value of MRI imaging

    Get PDF
    Carpal bone fractures in children are rare, and little is known about the appropriate tools to diagnose them, particularly in toddlers. We present a 2-year-old child with a capitate and hamate fracture. Based on our experiences with this case and on a review of the literature, we discuss the value of magnetic resonance imaging in carpal trauma in children

    Social use of facial expressions in hylobatids

    Non-human primates use various communicative means in interactions with others. While primate gestures are commonly considered to be intentionally and flexibly used signals, facial expressions are often referred to as inflexible, automatic expressions of affective internal states. To explore whether and how non-human primates use facial expressions in specific communicative interactions, we studied five species of small apes (gibbons) by employing a newly established Facial Action Coding System for hylobatid species (GibbonFACS). We found that, despite individuals often being in close proximity to each other, in social (as opposed to non-social contexts) the duration of facial expressions was significantly longer when gibbons were facing another individual compared to non-facing situations. Social contexts included grooming, agonistic interactions and play, whereas non-social contexts included resting and self-grooming. Additionally, gibbons used facial expressions while facing another individual more often in social contexts than non-social contexts where facial expressions were produced regardless of the attentional state of the partner. Also, facial expressions were more likely ‘responded to’ by the partner’s facial expressions when facing another individual than non-facing. Taken together, our results indicate that gibbons use their facial expressions differentially depending on the social context and are able to use them in a directed way in communicative interactions with other conspecifics

    I Know My Neighbour: Individual Recognition in Octopus vulgaris

    Background: Little is known about individual recognition (IR) in octopuses, although they have been abundantly studied for their sophisticated behaviour and learning capacities. Indeed, the ability of octopuses to recognise conspecifics is suggested by a number of clues emerging from both laboratory studies (where they appear to form and maintain dominance hierarchies) and field observations (octopuses of neighbouring dens display little agonism between each other). To fill this gap in knowledge, we investigated the behaviour of 24 size-matched pairs of Octopus vulgaris in laboratory conditions. Methodology/Principal Findings: The experimental design was composed of 3 phases: Phase 1 (acclimatization): 12 ‘‘sightallowed’’ (and 12 ‘‘isolated’’) pairs were maintained for 3 days in contiguous tanks separated by a transparent (and opaque) partition to allow (and block) the vision of the conspecific; Phase 2 (cohabitation): members of each pair (both sight-allowed and isolated) were transferred into an experimental tank and were allowed to interact for 15 min every day for 3 consecutive days; Phase 3 (test): each pair (both sight-allowed and isolated) was subject to a switch of an octopus to form pairs composed of either familiar (‘‘sham switches’’) or unfamiliar conspecifics (‘‘real switches’’). Longer latencies (i.e. the time elapsed from the first interaction) and fewer physical contacts in the familiar pairs as opposed to the unfamiliar pairs were used as proxies for recognition. Conclusions: Octopuses appear able to recognise conspecifics and to remember the individual previously met for at leas
