TL;DR: In this article, the role of transaction costs in a macroeconomic model of monopolistic competition is analyzed and it is shown that if there is sufficient increasing returns to scale in transaction technology, the economy exhibits multiple equilibria even if the production technology is constant or decreasing return to scale.

TL;DR: This article employed an automated text linguistic approach to create an indicator that measures the tone of the 1,618 speeches delivered by members of the Governing Council (GC) during the period 1999M1-2014M4.
Abstract: Speeches are an important vehicle for central bankers to convey individual views on the preferred policy stance. In this paper, we employ an automated text linguistic approach to create an indicator that measures the tone of the 1,618 speeches delivered by members of the Governing Council (GC) during the period 1999M1-2014M4. We then relate this variable to euro-area and national macroeconomic forecasts. Our key findings are as follows. First, inflation and growth expectations have a positive and significant impact on the hawkishness of a speech. Second, the voiced preferences of national central bankers largely coincide with the level of independence their banks had at the time of the Maastricht Treaty. Third, country-specific macroeconomic conditions matter for speeches delivered inside the central banker's home country but not for those made abroad. Fourth, differences in central banker preferences are the key source of variation in their speeches before the financial crisis, whereas divergent national economic conditions are the main factor in the second part of the sample.

TL;DR: Les resultats obtenus montrent que les concepteurs enoncent significativement plus de contraintes liees a l’utilisateur que de contraints liees au commanditaire.
Abstract: RESUME. Dans cette etude, des concepteurs de sites web debutants, professionnels et des utilisateurs doivent evaluer un site web realise par un concepteur exterieur. Cette recherche vise a determiner l’effet du niveau d’expertise de concepteurs de sites web et du niveau de precision du cahier des charges a traiter sur (1) le nombre et la nature de contraintes enoncees (liees a l’utilisateur vs liees au commanditaire) et (2) sur le nombre de problemes d’utilisabilite identifies lors de l’evaluation d’un site donne. Les resultats relatifs au nombre de problemes d’utilisabilite identifies par les concepteurs sont mis en correspondance avec ceux identifies par les utilisateurs. Les resultats obtenus montrent que les concepteurs enoncent significativement plus de contraintes liees a l’utilisateur que de contraintes liees au commanditaire. Neanmoins, peu de problemes d’utilisabilite sont identifies par les concepteurs, quel que soit le cahier des charges a traiter, ni meme par les utilisateurs. Des hypotheses pour tenter d’expliquer ces resultats ainsi que des perspectives de recherche pour tester ces hypotheses et pour aider les concepteurs a realiser des sites web plus simples d’utilisation sont proposees.

TL;DR: Rouelle, Venel and Macquer as mentioned in this paper showed that they shared Boerhaave's dual view of elements as constituents of matter and instruments in the hands of chemists.
Abstract: Students' manuscript notes from Rouelle's and Venel's chemistry courses offer a picture of chemistry in France in the mid-eighteenth century that is quite different from the one given by the Encyclopedie. The teachers shared Boerhaave's dual view of elements as constituents of matter and instruments in the hands of chemists. They clearly distinguished elements en masse, on which they conferred the instrumental role, from elements integrated in mixts, which, losing their common properties, constituted the real elements. This distinction was systematically applied to all four elements: Fire, Water, Air, and Earth. This article emphasises Venel's original views about Earth and Air. It also confirms the recent reassessment of the role attributed to Phlogiston in eighteenth-century chemistry. Students' notes also reveal that Rouelle, Venel and Macquer taught a consistent synthesis of Stahl, Newton, and Boerhaave.

TL;DR: This pilot study provides the first evidence that MEL intake alone or associated with intradialytic exercise displays potential immunoregulatory and anti-inflammatory effects and may be an appropriate anti- inflammation therapy for HD patients.
Abstract: The present study aimed to investigate the effects of melatonin (MEL) intake on systemic inflammation and immune responses during intradialytic exercise. Thirteen hemodialysis (HD) patients volunteered to participate in the current randomized-crossover study. Immunological responses were monitored in four HD sessions at different conditions: [Exercise (EX) + MEL], [EX + Placebo (PLA)], [Control (CON) + MEL] and [CON + PLA]. MEL (3 mg) or PLA was ingested 1 h before starting exercise or the equivalent time in CON condition. During all sessions, peripheral blood samples were collected to assess c-reactive protein, complete blood count, and immune cells phenotypes before HD (T0), immediately after exercise (T1) and 1 h after exercise (T2) or at corresponding times in the CON condition. HD therapy induced a significant decrease in natural killer (NK) (p = 0.001, d = 0.85; p < 0.001, d = 1.19, respectively) and CD8+ T-lymphocytes rates (p = 0.001, d = 0.57; p < 0.001, d = 0.75, respectively) at T1 and T2 compared to T0. MEL intake prevented the decrease in NK and CD8+ T-lymphocytes, increased the proportion of CD4+ T-lymphocytes at T1 and T2 compared to T0 (p = 0.002, d = 1.18; p = 0.001, d = 1.04, respectively) and decreased the proportion of CD14++CD16+ Monocytes at T2 compared to T0 (p = 0.02, d = 1.57) in peripheral blood during HD therapy. Similar results were found in [EX + MEL] and [EX + PLA] conditions. This pilot study provides the first evidence that MEL intake alone or associated with intradialytic exercise displays potential immunoregulatory and anti-inflammatory effects. The combination of MEL with intradialytic exercise may be an appropriate anti-inflammatory therapy for HD patients.
