Executive Committee The eighth session of the Executive Committee of the World Meteorological Organi zation (WMO) was held in Geneva from April 17 to 30, 1956 under the presidency of Mr. A. Viaut. Extensive discussion based on a report of a working group was held about plans for the International Geophysical Year 1957–1958, and several resolutions were passed asking all countries to participate, establishing a meteorological data center to ensure exchange of information, and setting up a method of financing. The Executive Committee also established a panel of experts to study meteorological as pects of atomic energy and discontinued its inquiry into the effect of atomic experimentation on the weather after agreeing that on the basis of the material submitted by the Secretary-General, there was no large-scale effect on weather from nuclear explosions. Material relating to a world climatic atlas was referred back to a working group which was asked to revise it for consideration at the second session of the Commission for Climatology scheduled for January 1957, and directives were laid down for consideration of the panel of experts on water resource development.

The idea for a Working Group (WG) on “Future Large Scale Facilities in Astronomy” grew from a discussion held on 20 August, 1994, during the IAU General Assembly in The Hague. The IAU Executive Committee approved its formation in August, 1995, and its composition in October, 1995. The WG will remain active at least until the XXIIIrd General Assembly in Kyoto in 1997. Members are: H. Butcher (Chairman), R. Ekers, B. Fort, N. Kardashev, M. Longair, F. Pacini, L. Rodriguez, G. Swarup, Y. Tanaka, H. Tananbaun, and L. Woltjer (ex officio). The WG carries out its work mostly by email and FAX.

The Executive Committee of the World Meteorological Organization (WMO) met in Geneva for its ninth session, September 24 to October 14, 1957, under the presidency of André Viaut. Discussing the International Geophysical Year (IGY), which had taken precedence in WMO activities, the committee approved the report of the working group on the IGY, re-established the group with revised terms of reference, and adopted a resolution on IGY world data centers. In its consideration of the meteorological aspects of the peaceful uses of atomic energy the committee endorsed the existing policy for action and examined the report of a panel of experts which had met in Geneva in December 1956. The committee pointed out the need for members to keep informed on the subject, and suggested that the Secretary-General prepare and distribute consolidated bibliographical lists from information supplied by members of the panel and by other WMO members. The Secretary-General was also authorized to negotiate an agreement with the International Atomic Energy Agency.

In the coming years, the Anthropocene Working Group (AWG) will submit its proposal on the ‘Anthropocene’ to the Subcommission of Quaternary Stratigraphy (SQS) and the International Commission on Stratigraphy (ICS) for approval. If approved, the proposal will be sent to the Executive Committee of the International Union of Geological Sciences (IUGS) for ratification. If the proposal is approved and ratified, then the ‘Anthropocene’ will be formalized. Currently, the ‘Anthropocene’ is a broadly used term and concept in a wide range of scientific and non-scientific situations, and, for many, the official acceptance of this term is only a matter of time. However, the AWG proposal, in its present state, seems to not fully meet the requirements for a new chronostratigraphic unit. This essay asks what could happen if the current ‘Anthropocene’ proposal is not formalized by the ICS/IUGS. The possible stratigraphic alternatives are evaluated on the basis of the more recent literature and the personal opinions of distinguished AWG, SQS, and ICS members. The eventual impact on environmental sciences and on non-scientific sectors, where the ‘Anthropocene’ seems already firmly rooted and de facto accepted as a new geological epoch, are also discussed. This essay is intended as the editorial introduction to a Quaternary special issue on the topic.

The Impact

AbstractModern data center networks typically adopt multi-rooted tree topologies such leaf-spine and fat-tree to provide high bisection bandwidth. Load balancing is critical to achieve low latency and high throughput. Although the per-packet schemes such as Random Packet Spraying (RPS) can achieve high network utilization and near-optimal tail latency in symmetric topologies, they are prone to cause significant packet reordering and degrade the network performance. Moreover, some coding-based schemes are proposed to alleviate the problem of packet reordering and loss. Unfortunately, these schemes ignore the traffic characteristics of data center network and cannot achieve good network performance. In this paper, we propose a Heterogeneous Traffic-aware Partition Coding named HTPC to eliminate the impact of packet reordering and improve the performance of short and long flows. HTPC smoothly adjusts the number of redundant packets based on the multi-path congestion information and the traffic characteristics so that the tailing probability of short flows and the timeout probability of long flows can be reduced. Through a series of large-scale NS2 simulations, we demonstrate that HTPC reduces average flow completion time by up to 60% compared with the state-of-the-art mechanisms.
