INTRODUCTION: Media accountability

The sole aim of media is to make as much money as they can. Or again, the media are to serve only the people in power, political or economic. If you agree to that, you might as well stop reading this. This issue of Pacific Journalism Review is predicated on the principle that media should serve the public. Journalists can only achieve that if they enjoy independence from financial and political pressures. It is not often enough underlined that they cannot enjoy that independence without the support of the public, the masses of voters and consumers. There is no way the profession can obtain public support unless it listens to readers/listeners/viewers— unless it is accountable to them

High magnetic field induced charge density waves and sign reversal of the Hall coefficient in graphite

We report on the investigation of magnetic field induced charge density wave and Hall coefficient sign reversal in a quasi-two dimensional electronic system of highly oriented pyrolytic graphite under very strong magnetic field. The change of Hall sign coefficient from negative to positive occurs at low temperature and high magnetic field just after the charge density wave transition, suggesting the role of hole-like quasi-particles in this effect. Angular dependent measurements show that the charge density wave transition and Hall sign reversal fields follow the magnetic field component along the c-axis of graphite

Alteration and release of aliphatic compounds by the polychaete Nereis virens (Sars) experimentally fed with hydrocarbons

In the laboratory, marine worms were fed with a mixture of algae and several aliphatic hydrocarbons for 15 days. After ingestion by the worms, 34.9% of hydrocarbons are found in the faeces and only 3.1% accumulated in the gut. The comparison between the initial mixture and the faeces shows that the worm’s digestive process lead to changes in the distribution of the n-alkane mixture. These changes are different from those only due to physical processes in the experimental conditions. In our experiment, no variation in the distribution of hydrocarbons in faeces with time and no microbial hydrocarbon biodegradation were evidenced. Our results suggest that marine worm feeding can substantially affect the fate of hydrocarbons in the sedimentary marine ecosystem by predominantly stimulating dissolution processes

Le Premier Amendement : un mythe

Ce papier, plein de verve, d’humeur et d’humour, pose, comme sait si bien le faire l’auteur, des questions profondes sous une apparence paradoxale. Il a été présenté lors d’un colloque sur le Premier amendement organisé à l’Université Lumière-Lyon 2 les 17 et 18 janvier 2003. Certaines communications ont été publiées dans le volume XXIV, n°1 (2003), « Le premier amendement : un modèle américain des libertés » (sous la direction de Vincent Michelot) de la Revue Tocqueville

Media Accountability Systems

Autor je postavio MAS kao sustav vrijednosti suvremenog novinarstva i samoregulacije profesije koja pruža odgovore na goruća pitanja poštovanja etičkih načela i deontologije novinarstva. Na temelju MAS-a osnivaju se vijeća za medije koji mogu utjecati na poštovanje profesionalnih standard novinarstvaM*A*S could have contributed more if they had been used more. What was needed at the beginning of the 21st century was a wider, clearer awareness of what media accountability meant for the pres

Hydrocarbon influence on denitrification in bioturbated Mediterranean coastal sediments

An in situ experiment has been carried out inbioturbated Mediterranean coastal marine sediments (Gulfof Fos) in order to study the influence of hydrocarbons ondenitrification after 1, 4 and 6 months. In theabsence of hydrocarbons in the control sediments, the presenceof macrofauna stimulated denitrificationby 160%. This stimulation is induced by sediment reworkingthat favours both direct NO-3 supply fromthe water column and the penetration of O{2}, which in turnstimulated nitrification, the other source ofNO-3 in sediment. The presence of hydrocarbons in theexperimental sediments either stimulated orinhibited the denitrification. The denitrification response tothe presence of hydrocarbon is dependent onthe quantity of matter buried by the macrofauna activity. Insmall quantities, the organic matter relatedto hydrocarbons 120% enhanced the denitrification compared tothe controls. On the other hand, whenburied hydrocarbon concentrations were higher (>100 mgsaturated hydrocarbon fraction kg-1 drysediment), the denitrification was inhibited.On the basis of the results obtained, a descriptive model ofthe patterns of denitrification in relation to the presence ofmacrofauna and the distribution of hydrocarbons in sediments is proposed

Inhibition of denitrification by hydrocarbons in marine sediments. Role of Nereis diversicolor

An in vitro experiment has been carried out in order to illustrate the influence of the burrowing polychaete Nereis diversicolor on denitrification in hydrocarbon-loaded sediments. After 15 and 45 days, the denitrification activity in the different contaminated or non-contaminated control (without macro-fauna) and experimental (colonized by polychaetes) sediments was compared. In control contaminated sediments, the inhibition of denitrification is solely located in the surface layer (0–2 cm). In the presence of polychaetes, the hydrocarbon buried in the burrows extends the inhibition of denitrification in the sediment. As a function of the quantity of buried hydrocarbon, the inhibition of denitrification is observed up to a depth of 6 and 10 cm, after 15 and 45 days, respectively
