Who is responsible for health and safety of temporary workers? EU and UK perspectives

There have been several attempts to provide certain protection to temporary agency workers at the EU level by Directive 91/383/EEC in respect of health and safety and most recently by Directive 2008/104/EC in respect of other working conditions. However, the precarious employment status of temporary workers has been a stumbling block in clear understanding of who owes duties and responsibilities for health and safe of these workers. By seeking to address this issue, the paper analyses the existing legal provisions relating to health and safety of temporary agency workers at the EU and UK levels in the context of a more general problem associated with the employment status of such workers, and suggests a number of alternatives to the existing legal regime which could potentially clarify the situation

An overview of aid effectiveness, determinants and strategies

This paper provides an overview of issues relating to aid effectiveness. It argues that it is impossible to give a definitive answer to the question of whether aid is effective, and that it is more useful to ask what can be done to make aid more effective. The paper then groups the various determinants of aid effectiveness, as well as strategies to improve effectiveness, under three headings: the performance of the recipient (developing) country government; the performance of the aid agency of the donor (developed) country; and the interaction between the two. This provides, it is argued, a useful framework within which to understand different and competing arguments about how to improve aid effectiveness.aid, aid effectiveness

Neural coding of high-frequency tones

Available evidence was presented indicating that neural discharges in the auditory nerve display characteristic periodicities in response to any tonal stimulus including high-frequency stimuli, and that this periodicity corresponds to the subjective pitch

The TAVERNS emulator: An Ada simulation of the space station data communications network and software development environment

The Space Station DMS (Data Management System) is the onboard component of the Space Station Information System (SSIS) that includes the computers, networks and software that support the various core and payload subsystems of the Space Station. TAVERNS (Test And Validation Environment for Remote Networked Systems) is a distributed approach for development and validation of application software for Space Station. The TAVERNS concept assumes that the different subsystems will be developed by different contractors who may be geographically separated. The TAVERNS Emulator is an Ada simulation of a TAVERNS on the ASD VAX. The software services described in the DMS Test Bed User's Manual are being emulated on the VAX together with simulations of some of the core subsystems and a simulation of the DCN. The TAVERNS Emulator will be accessible remotely from any VAX that can communicate with the ASD VAX

Rainbow Schlieren

The rainbow schlieren is an apparatus in which the usual schlieren knife edge cutoff is replaced by a radial rainbow filter with a transparent center and an opaque surround. With this apparatus most refractive index nonuniformities in the test section appear varicolored whereas uniformities appear white. The rainbow schlieren is simple, easy to use, and relatively inexpensive and gives much greater detail regarding nonuniformities than does the ordinary schlieren. Moreover, the rainbow schlieren permits quantitative evaluation of certain refractive index distributions, including those involving turbulence, by simple calculations

Thermal fatigue and oxidation data on TAZ-8A, MAR-M 200, and Udimet 700 superalloys

The fluidized bed technique was used to determine the relative thermal fatigue and oxidation resistance of three superalloys: TAZ-8A, Mar-M 200, and Udimet 700. The alloys TAZ-8A and MAR-M 200 were also tested in the directionally-solidified form. For the 13 combinations of composition, solidification method, surface protection, and specimen geometry, the cycles to cracking varied from 1250 to 15,000. The alloy/coating having the best resistance to thermal fatigue cracking was coated directionally-solidified NASA TAZ-8A. This combination also had excellent oxidation resistance

Loudness (annoyance), prediction procedure for steady sounds

Method has been devised to predict loudness level of any steady sound solely from its measured power spectrum level. Method is based on assumption that, with respect to loudness sensation, the human auditory system acts as open-loop transmission system with transmittance function determined from measured tone curves
