Equitisation and stock-market development : the case of vietnam
No full textEquitisation is de Vietnamese variant van privatisering. Het proefschrift van Truong Dong Loc gaat voor een groot deel over de vraag wat het effect van equitisation is op de prestaties van de bedrijven. Uit het onderzoek bleek dat de winstgevendheid, efficiëntie en het inkomen van werknemers toenamen. Opmerkelijk, want het verschil tussen equitisation en privatisering is dat bij equitisation het aandeel dat de staat en werknemers behouden, aanzienlijk groter is dan bij privatisering. In de literatuur worden de verbeterde prestaties van geprivatiseerde bedrijven vaak toegeschreven aan de controle van aandeelhouders van buitenaf. Een bewering die nu dus enigszins op losse schroeven staat.

Panisea sondangii Aver. 2023, comb. nov.
No full textPanisea sondangii (Vuong, Aver. & V.H.Bui) Aver., comb. nov. ≡ Coelogyne sondangii Vuong, Aver. & V.H.Bui in, D.T. Vo et al. (2022: 201, fig. 1). Type: — VIETNAM. Lai Chau Province, Sin Ho District, Lang Mo Commune, forest around Tu Cua Phin Village, 23 March 2022, Truong Ba Vuong, Bui Van Huong, BV 1357 (holotype VNM 00069946). Notes:—Following almost all recent orchid assessments and monographs (Seidenfaden 1986, 1992, Lund 1987, Pearce & Cribb 2002, Schuiteman et al. 2008, Chen et al. 2009, Rokaya et al. 2013: 539, Zhou et al. 2016: 34, Ormerod et al. 2021: 74), we accept Panisea (Lindley 1833: 44) Steudel (1841: 265) as a genus separate from Coelogyne Lindley (1821: t. 33) due to clear morphological evidence. Hence, we proposed the new nomenclatural combination made above. Data on ecology, phenology, distribution, and conservation status were reported earlier (Vo et al. 2022).Published as part of Averyanov, Leonid V., Nguyen, Van Canh, Truong, Ba Vuong, Nguyen, Khang Sinh, Nguyen, Cuong Huu, Maisak, Tatiana V., Doan, Nga Thi, Nguyen, Tuan Hoang, Pham, Van The, Dat, Pham Thi Thanh, Thai, Tran Huy, Nguyen, Van Khuong & Trinh, Ngoc Bon, 2023, New orchids in the flora of Vietnam VI (Orchidaceae, tribes Arethuseae, Cymbidieae, Diurideae, Epidendreae, Vandeae, and Vanilleae), pp. 87-110 in Phytotaxa 597 (2) on page 93, DOI: 10.11646/phytotaxa.597.2.1, http://zenodo.org/record/792919

(Fig. 4). ≡ Cirrhopetalum refractum Zollinger 1847: 456. Type:— INDONESIA. Java, Zollinger, 2261 (G00165064 photo!). ≡ Phyllorkis refracta (Zollinger 1847: 456) Kuntze (1891: 677). ≡ Tripudianthes refracta (Zollinger 1847: 456) Szlachetko & Kras (2007: 96). Habitat and phenology: —Epiphyte on tall trees in primary evergreen broad-leaved forests. Flowering observed in December–February. Distribution: — Vietnam (Lam Dong, Gia Lai, Dak Nong, Binh Phuoc, Dien Bien provinces), Bhutan, India, Myanmar, Thailand, Java and Sumatra. Proposed conservation status:—According to currently available data, B. refractum seems quite common in Vietnam. Due to attractive nature of flowers, the species is widely collected for trade. Based on the national EOO 148,826.741 km 2 and AOO 28.000 km 2, and in accordance with IUCN criteria (IUCN, 2022), the species should be assessed in Vietnam as VU B2ab(v). The verifiable data for this species’ conservation status outside Vietnam is not available. Note:—Common in Vietnam, with relatively large flowers having a large dorsal sepal. The species is sometime misidentified as B. kanburiense; the main differences is indicated under the note for B. kanburiense. The drawing of Pham Hoang Ho (1992: 844) named as B. refractum possibly based on specimens of Tixier 15 (P 00348218) having a very small dorsal sepal typical for B. wallichii.
