English-Language Periodicals in Parisian Reading Rooms and the Cross-Channel Transfer of Editorial Innovation (1800–65)

In the historical context of the development and modernization of the press, of an increasingly intense transnational circulation of ideas and of editorial styles, this essay sets out to analyze the reasons why reading rooms specialized in the foreign-language press, especially in English—for which the market was narrow—were successful in Paris during the first half of the nineteenth century. It examines the consequences of the circulation of the normally difficult to access British periodicals and newspapers, such as the Edinburgh Review, the Quarterly Review and the Westminster Review present in these reading rooms, on the transformation of the French media system. In the 1850s and 1860s, the wind started to change direction. By then, on the other side of the Channel, Alexander Macmillan and Mathew Arnold had become fervent admirers of the famous Revue des deux mondes. This turnabout testifies to the complexity of the mechanisms at work behind transnational cultural transfers and media innovation in France and in Britain at the time.

Asymmetric Demand Response When Prices Increase and Decrease: The Case of Child Healthcare

This study tests whether demand responds symmetrically to price increases and decreases—a seemingly obvious proposition under conventional demand theory that has not been rigorously tested. Exploiting the rapid expansion in Japanese municipal subsidies for child healthcare in a difference-in-differences framework, we find evidence against conventional demand theory: when coinsurance, our price measure, increases from 0% to 30%, the demand response is more than twice that to a price decrease from 30% to 0%. This result indicates that while economists and policymakers pay little attention, price change direction matters and should be incorporated into welfare analysis.

LNG Loading Lines High Surge Analysis

Proper design of LNG loading lines and verification of emergency shutdown (ESD) interlock systems are critical in ensuring overall safety of the LNG facility. During an emergency, ESD interlock is activated with ESD valves closure initiated simultaneously with all loading pumps trip and the kickback valves open. During the ESD valves closure, the pipeline can be exposed to a risk of high surge pressures exerted onto the wall. A pressure surge or liquid hammering phenomenon in piping systems can be caused by a fluid in motion forced to stop or change direction suddenly (rapid momentum change) and also due to cavitation effect. Cavitation is caused by the formation and instantaneous collapse of vapour bubbles. The collapsing bubbles exert severe localized impact forces that can result in pressure surges. This paper discusses the methodology used to evaluate any potential occurrence of surge and the peak pressure associated with it, using several case studies for analysis. This paper also shares best practice identified from the study to facilitate with safe operations at an LNG loading facility.

Intersection-Based Routing with Fuzzy Multi-Factor Decision for VANETs

Due to the limitations of the urban environment, the data transferred between vehicles can only change direction at the intersections. Therefore, the routing decision at an intersection will largely affect the overall routing decision. In this article, we propose an Intersection-Based Routing with Fuzzy Multi-Factor Decision (IRFMF), which utilizes several factors to decide the next road segment. In the scheme, each intersection introduces three factors including the direction, the number of lanes, and the traffic. After the fuzzification and defuzzification of these factors, the candidate segment with the highest evaluation will be selected. The simulation shows a significant improvement of VANETs performance on packet delivery ratio and end-to-end delay.

Effect of simulated tennis steps and slides on tread element friction and wear

In hard court tennis, players change direction by either stepping or sliding. The shoe–surface friction during these movements is crucial to player performance. Too little friction when stepping may result in a slip. Too much friction when attempting to slide could cause the player to move only a short distance, or to fail to slide. To understand the influence of tread design on shoe–surface friction in tennis, experiments were performed on individual shoe tread elements that replicated the tribological conditions typically experienced during hard court step and slide movements. Tread element orientation had no effect on the static friction in step movements, but longer tread elements (in the sliding direction) had 9% lower dynamic friction during slide movements (p < 0.001). The friction between tennis shoe tread and hard court tennis surfaces is also shown to be influenced by the tread’s sliding history, and the wearing pattern that forms on the surface of the rubber.
