China's Emergence and Its Implications for Europe's Economies
Sandra Poncet 연세대학교 동서문제연구원 2015 Global economic review Vol.44 No.4
This paper assesses how the competition between China and the EU in export markets has affected the trade performance of European countries. It first draws on a comparison between Germany and France before turning to discuss the economic and social impact of China’s internationalization on Europe’s economies. The results suggest that even in the recent years when China has gained prominence, it should not be blamed for more than half of the measured effects for emerging countries.
`French Firms Penetrating Asian Markets : Role of Export Spillovers
( Sandra Poncet ),( Florian Mayneris ) 세종대학교 경제통합연구소(구 세종대학교 국제경제연구소) 2013 Journal of Economic Integration Vol.28 No.2
In this study, we explore the role of export spillovers on the capacity of French firms to penetrate Asian markets. We confirm previous results, that is, the presence of other exporters raises the probability that firms start exporting a given product to a given country in the case of France. We find that export spillovers are more important for exports to Asia than to other destinations. Moreover, the presence of other exporters appears particularly beneficial to small and less productive firms. More intense benefits for start-up companies are observed in tough Asian markets characterized by low GDP per capita and tough administrative procedures on imports.

This paper documents business cycles` fluctuations in Chinese provinces. China`s de facto federalism, within a context of great geographical and economic diversity, suggests the great importance of policy coordination between provinces. We investigate the role of various potential determinants of provincial business cycles` synchronization. We consider exogenous factors like distance and size as well as policy factors such as industrial, fiscal and trade policy. Results emphasize the benefits of domestic trade and local fiscal policy rationalization on the stabilization of output fluctuations. However, they also identify international trade and local economic policy heterogeneity as growing centrifugal forces.

Purpose: This study included all patients treated at the University Hospital of Geneva for a first episode of uncomplicated diverticulitis. Risks of recurrence and treatment failure were evaluated by comparing the results between short-course and long-course intravenous (IV) antibiotic therapy groups. Methods: The records of all patients hospitalized at our facility from January 2007 to February 2012 for a first episode of uncomplicated diverticulitis (Hinchey Ia), as confirmed by computed tomography, were prospectively collected. We published an auxiliary analysis from this registered study at Clinicaltrials.gov (identifier number: NCT01015378). Two groups of patients were considered: one received a short-course IV antibiotic arm (ceftriaxone and metronidazole) for up to 5 days (followed by 5 days of oral antibiotics); the other received a long-course IV arm between days 5 and 10. The primary outcome was the recurrence-free survival time. Results: Follow-up was completed for 256 patients—50% men and 50% women, with a median age of 56 years (range, 24–85 years). The average follow-up was 50 months (range, 19–89 months). Of the 256 patients included in the study, 46 patients received a short-course IV antibiotic treatment and 210 received a long-course treatment. The recurrence-free survivals were very similar between the two groups, which was supported by a log rank test (P = 0.772). Four treatment failures, all in the long-course IV antibiotic treatment group, occurred. Conclusion: Treatment of diverticulitis with a short IV antibiotic treatment is possible and does not modify the recurrence rate in patients with uncomplicated diverticulitis.
Nonlinear Instability of the Two-Dimensional Striation Model About Smooth Steady States
Besse, C.,Degond, P.,Hwang, HJ.,Poncet, R. Marcel Dekker, Inc 2007 Communications in partial differential equations Vol.32 No.7
<P> The two-dimensional striation model consists of a nonlinear system of PDE's which arises in the modeling of the ionospheric plasma. The local-in-time existence of strong solutions is first proved using Banach's fixed point theorem. Then, under physically relevant assumptions, the system is shown to be nonlinearly unstable as soon as it is linearly unstable. Moreover, the instability occurs before the possible blow-up time of the solution. The proof relies on an earlier work of Hwang and Guo (2003). The first step of the proof is to investigate under which conditions the linearized system is unstable and to prove that its spectrum is bounded, by means of a variational formulation. The second one consists in constructing a family of solutions depending on the parameter &dgr; measuring the smallness of the perturbation to the steady-state. Thanks to the boundedness of the linearized spectrum, this family of solutions is shown to be unstable by means of a power series expansion in &dgr;.</P>

This study was designed to measure the effect of regrowth age of Digitaria decumbens (D. decumbens) on the intake and dynamics of digesta in the rumen of rams. Six Black-belly rams (mean liveweight: 51.6 (s.d. 0.68) kg) fitted with rumen cannulae were fed twice daily a 14-, 28-, 42- and 56-day old fresh D. decumbens successively for 4 experimental periods. The daily dry matter intake decreased curvilineary from 75.2 to 48.5 (s.e. 2.0) g/kg $BW^{0.75}$ as the age of the D. decumbens grass increased from 14 to 56 days. Dry matter intake for the first 3 h after the morning meal was 863.6, 598.3, 576.4 and 401.5 (s.e. 55.6) g for the 14-, 28-, 42- and 56-day old grasses respectively. The pool of NDF in the rumen at the end of the 3-h feeding period did not vary significantly among the four diets. Twelve hours after the beginning of the morning meal, the pool of NDF increased with the forage regrowth age. Within the total pool of NDF, the pool of large particles tended to increase with the regrowth age. It was concluded that high intake was associated with fast evacuation of NDF from the rumen. Moreover, digestion (cellulolysis) rate and degree of particle reduction by rumination are highly correlated, though speed of physical degradation of forage seems to be the driving force behind intake.

A pollen/food-associated syndrome (PFAS) has been described between peach and cypress pollen. Cross-reactive allergens were characterized which belong to the Gibberellin-regulated protein (GRP) family, BP14 in cypress pollen and Pru p 7 in peach. GRP are small cationic protein with anti-microbial properties. A patient suffering from a peach/cypress syndrome was explored clinically and biologically using 2 types of immunoglobulin E (IgE) multiarray microchip, immunoblots and a basophil activation test to assess the clinical relevance of various extracts and purified allergens from fruits or cypress pollen. In addition to PR10 sensitization, the patient showed specific IgE to Pru p 7, BP14 and allergen from pomegranate. These last 3 allergens and allergenic sources are able to induce ex vivo basophil activation characterized by the monitoring of the expression of CD63 and CD203c, both cell surface markers correlated with a basophil mediator release. Up to 100% of cells expressed CD203c at 50 ng/mL of BP14 protein. In contrast, snakin-1, a GRP from potato sharing 82% sequence identity with Pru p 7 did not activate patient's basophils. These results strongly suggest that, like Pru p 7, BP14 is a clinically relevant allergenic GRP from pollen. Allergen members of this newly described protein family are good candidates for PFAS where no cross-reactive allergens have been characterized.
