Specimen examined. [CNU] Holotype: 1♂, Cuc Phuong National Park (20°19´07˝ N 105°36´18˝E), Ninh Binh Prov., Vietnam, 10.v.2017, on Schizostachyum dullooa, J. Kim leg.; [CNU] Paratypes: 5♂♂ 6♀♀, same data as holotype; [VNMN] Paratypes: 1♂ 1♀, same data as holotype. Host: Schizostachyum dullooa (Gamble) Majumdar (Poaceae)* (Fig. 3). Biology. This species was only collected on Schizostachyum dullooa with specific host relationship. All nymphal stages (1–5 instars) and adults of this species were found on this host plant. Etymology: Named after I. Lansbury as a recognition for his taxonomical study on the Mecistoscelini; a noun in genitive case. Distribution: Vietnam (Northern). Remarks. This species is similar to its congener M. scirtetoides, but can be distinguished by larger body; right paramere with three spines; and distinct endosomal sclerites of male genitalia. In particular, the character state (three spines of right paramere) is consistent, which can be one of the important characters for this species. Lansbury (1963) also indicated the numbers of spines were one of the diagnostic characters of Mecistoscelis species in comparative notes and key.Published as part of Kim, Junggon, Roca-Cusachs, Marcos, Pham, Hong-Thai & Jung, Sunghoon, 2018, A new species of the genus Mecistoscelis Reuter from Vietnam (Hemiptera: Miridae: Mecistoscelini), with key to Mecistoscelis species, pp. 396-400 in Zootaxa 4434 (2) on pages 397-399, DOI: 10.11646/zootaxa.4434.2.13, http://zenodo.org/record/129054

La persistance du déficit commercial américain dans les années 1980
No full textDas anhaltende amerikanische Handelsdefizit,
von Yannick L'Horty, Kim Sébastien Pham.
Seit mehr als zehn Jahren häuft die Handelsbilanz der Vereinigten Staaten ununterbrochen Defizit um Defizit an. Der 1986 begonnene allmähliche Abbau ist jedoch Anfang der 90er Jahre wieder ins Stocken geraten. Zur Erklärung der Handelsbilanzbewegungen werden gewöhnlich zwei Hauptdeterminanten angeführt: der konjunkturelle "Lag" und die Preiswettbewerbsfähigkeit. In diesem Artikel werden nun die Auswirkungen dieser beiden Determinanten auf die Entwicklung des amerikanischen Defizits seit Anfang der 80er Jahre analysiert und diskutiert.The Enduring American Trade Deficit,
by Yannick L'Horty and Kim Sébastien Pham.
The United States trade deficit is the result of ten consecutive years of deficits. Its gradual decrease, which started in 1986, is now tailing off in the early 1990s. Two main deciding factors are traditionally put forward to explain movements in balances of trade: the business lag and price competitiveness. The contributions of these determining factors to the development of the American deficit since the beginning of the 1980s are analyzed and discussed.La persistance du déficit commercial américain dans les années 1980,
par Yannick L'Horty, Kim Sébastien Pham.
La balance commerciale des États-Unis cumule plus de dix années consécutives de déficits, et son redressement progressif, amorcé en 1986, s'essoufle au début des années 1990. Pour expliquer les mouvements des balances commerciales, deux principaux déterminants sont traditionnellement mis en avant : le décalage de conjoncture et la compétitivité prix. Les contributions de ces déterminants à l'évolution du déficit américain depuis le début des années 1980 sont analysées et discutées.Persistencia del déficit comercial estadounidense,
por Yannick L'Horty y Kim Sébastien Pham.
La balanza comercial de los Estados Unidos lleva acumulados más de diez años consecutivos de déficits y su recuperación progresiva, inidada en 1986, comenzó a perder fuerza a prindpios de los años 90. Para explicar los movimientos de las balanzas comertiales, suelen ponerse de relieve dos printipios determinantes: la differencia de coyuntura y la competitividad-precios. Por último se analiza y discute la contribución de estos principios a la evolución del déficit estadounidense desde printipios de los años 80.L'Horty Yannick, Pham Kim Sébastien.
