Ta Quynh Hoan video oral history interview and transcript
No full textThis recording and transcript form part of a collection of oral history interviews conducted by the Vietnamese American Heritage Foundation and donated to the Chao Center for Asian Studies at Rice University. This collection includes video recordings of interviews with Vietnamese Americans native to or living in Texas. This interview forms part of the national 500 Oral Histories Project conducted by the Vietnamese American Heritage Foundation.Ta Quynh Hoan was born in Ha Dong on 29 December 1945. Her family followed French troops to South Vietnam at the end of 1954, around the age of 10. Her mother and some other family members remained in the North. She visited them sporadically. When asked about her childhood, Ta Quynh Hoan speaks about her family genealogy and dynamic. Her paternal grandfather had at least four wives. Her biological father had 14 siblings. She specifically speaks about her grandfather’s third wife who lived with her family and had an exceptional singing ability. With regards to her education, Ta Quynh Hoan remembers being punished frequently by the nuns. It took her three tries to enter her school, making her a few years older than her peers
Effects on wave break, sea dike protection of the tree planting formula in the coastal salinity inundated areas
No full textField investigation by Vuong Van Quynh on the dissipation of wave energy in a mangrove field off the coast of southern Vietnam. Based on regression analysis a formula has been developed to determine the wave height decrease as function of the tree density and the tree sizes

Ru Diep and the Quynh Van culture of central Vietnam
No full textExcavations in 2015 at the site of Ru Diep in north-central Vietnam (Ha Tinh Province) raise significant questions about the transition into the Neolithic in this region, more than 5000 years ago. The material culture from the site reveals a mixture of both pre-Neolithic (Quynh Van culture) and Neolithic elements, in a shell mound context. The C14 dates for the site suggest that the surviving layers were deposited between outer limits of 3200 and 2900 cal. BC, but Bayesian analysis indicates a likely accumulation in less than 50 years. This date is almost one millennium older than expected for Neolithic-related materials in north-central Vietnam
Marché et production : une dynamique rénovatrice. Le cas de l'électroménager
No full textThe author, who thinks that the sociology of labor focuses too much on the modernization of manufacturing processes, tries to show that, if new technologies are taken into account in terms of the functionality of a consumer product, then deep changes are necessary in the organization of firms, in both the manufacturing process and methods of personnel management.Estimant que la sociologie du travail met trop l'accent sur la modernisation du processus de fabrication, l'auteur cherche à montrer que la prise en compte des technologies nouvelles dans la fonctionnalité d'un produit de consommation impose des modifications très profondes dans l'organisation de l'entreprise, jusques et y compris, dans les processus de fabrication ainsi que dans les méthodes de gestion du personnel.Delaunay Quynh.

Frontal to orbital margins cristate, lined with low, rounded granules, infraorbital margin (Fig. 5 a) interrupted just below external orbital angle; suborbital region smooth, without granules; subhepatic region covered with short rows of granules. External orbital angle right angled, slightly directed inwards, outer margin length about two times inner margin, outer margin cristate, lined with small granules, epibranchial tooth disconnected from outer margin of external orbital angle by short gap of crista, short, directed anteriorly; anterolateral margin moderately convex laterally, cristate, regularly lined with similar-sized granules, posterolateral margins convergent posteriorly. Posterior margin of epistome (Fig. 5 a) with three lobes, median longest, narrow, sharp, margin between median, lateral lobes composed of elongated granules.</p> <p>Ischium of third maxilliped broadly rectangular exopod flagellum longer than half width of merus.</p> <p>Male cheliped carpus with rugose outer surface, inner angle with sharp, long tooth, followed ventro-proximally by one to two small teeth; chela with swollen palm, scattered with low, rounded granules from outer to lower half of inner surfaces (Fig. 5 b); fingers as long as palm, straight, slightly hook-shaped distally, cutting edge regularly lined with teeth, without gap when closed. Male abdomen (Fig. 4 b) tongue-shaped, first somite with distal margin rimmed; second somite with sublateral notch on distal margin, forming rounded lateral lobes; third somite widest; sixth somite longer than telson, telson longer than width. G1 (Fig. 3 d, e) with distal third curved outwards; subterminal segment with wide convexity on proximal two-fifths of outer margin, distal part of outer margin concave, connected dorsally to shallow transverse slope; distal segment relatively stout, tip slightly directed proximally in dorsal view, dorso-outwards in anterior view, groove for G2 on dorso-lateral surface medially, on lateral surface distally, proximally, elongated opening on distal outer margin, dorsal flap (protuberance of ventral outer surface) low, slightly visible from dorsal view. G2 (Fig. 3 f) longer than G1, flagellum curving outwards, U-shaped.</p> <p> <b>Live colouration.</b> The dorsal carapace, chelipeds, and walking legs are mostly brownish-grey. The upper half of the third maxillipeds (from the palp to the anterior part of the ischium) and the suborbital, pterygostomial, subhepatic, and subbranchial regions are a light purplish. The fingers of the chelae are reddish-brown with the tips white, and the chela is dark to light reddish-brown (Fig. 6 e, f).</p> <p> <b>Habitat and distribution.</b> This species was collected from a mountain stream in a forested area, with a rock, sand and sometimes muddy bottom, at Ba Vi National Park in northern Vietnam. It is so far known only from its type locality.</p> <p> <b>Etymology.</b> The new species is named after the type locality, Ba Vi National Park. The name is used as noun in apposition.</p> <p> <b>Remarks.</b> <i>Indochinamon bavi</i> <b>n. sp.</b> can be distinguished from <i>I. kimboiense</i> by the characters of the chela, the carapace, and the G1. In <i>I. bavi</i> <b>n. sp.</b>, the palm of the chela is only sparsely granular (Fig. 5 b), the suborbital region of the carapace lacks granules, smooth (Fig. 5 a), and the opening of the distal tip of the G1 is placed laterally (Fig. 3 d, e). In contrast, <i>I. kimboiense</i> has the palm of the chela densely granular (Fig. 2 b), the suborbital region of the carapace is granular (Fig. 2 a), and the distal opening of the G1 is placed on ventral surface (Figs. 3 a, b).</p>Published as part of <i>Naruse, Tohru, Quynh, Nguyen Xuan & Yeo, Darren C.
