Heterogeneity in behavioural response to pricing policies in the transition from motorcycles to private cars in motorcycle-based societies
No full textPricing instruments are widely seen as an effective tool for reducing the travel demand for private vehicles. In contrast to developed countries, the design of pricing policies in certain developing countries is more challenging, owing to the mixed use of private cars and motorcycles. This study argues for the existence of a transitional group of motorcycle users who will switch to being car users. An investigation of the behavioural responses to a pricing policy from private car users and motorcycle users is implemented in Ho Chi Minh City, Vietnam. A propensity score-matching technique is used to identify the transitional group. The results regarding the mode choice models for various pricing policies show similar responses between the transitional motorcycle users and car users. Such characteristics of the transitional group imply that ignorance of travellers' heterogeneity may cause significant bias, especially when modelling pricing policies.This research was financed by the Special Research Fund of Hasselt University.

PHOENIX/PHUNG HOANG: A STUDY OF WARTIME INTELLIGENCE MANAGEMENT (VIETNAM WAR, COUNTERINSURGENCY)
No full textPhoenix/Phung Hoang (1967-1970) was an administrative-military operation for South Vietnam, conceived by the U.S. Central Intelligence Agency (CIA) and administered in conjunction with the Military Assistance Command of the U.S. Army and the Government of South Vietnam. The author, recently deceased (d. 1982), had a long and distinguished career with the CIA, spent some 20 years in Vietnam, and was deeply involved with the Phoenix/Phung Hoang Program. Phoenix/Phung Hoang was a new administrative operation and concept geared to the guerrilla tactics of modern warfare rather than the "big-unit" operations favored in the past. Theoretically, the Program was part of a larger Pacification Effort. In practice, Phoenix/Phung Hoang concentrated on new approaches to counter-insurgency. The author provides an indepth, detailed analysis of logistics, bureaucratic conflicts, U.S.-host government difficulties, legal problems, and the interrelationships of civilian and military components. The conclusions are carried into a philosophical or theoretical matrix. They deal with the changing nature of war, command and operations, policy-making, and decision-making, moral implications, law and due process, labeling, and media. The significance of the study lies primarily in the sources used as documentation. The author was able to obtain declassification of materials previously categorized by the Army and the CIA as "confidential" or "secret." These materials demonstrate, among other things, a significant official terminology. "Pacification" describes counter-insurgency. "Neutralization" refers to killings, assassinations, and abductions relating to "quotas" and "bounties" targeted on both the civilian and military enemy population. For both the general reader and the specialist on wartime intelligence mangement, there is a unique perspective, authentically documented. The implications are far-reaching.</p
APPROACHING THE BELIEF OF THANH HOANG IN SOUTHEASTERN VIETNAM FROM THE PERSPECTIVE OF FUNCTIONAL THEORY
No full textThe belief in Thanh Hoang (tutelary deities) is an important part of the spiritual life of Vietnamese village communities. This article focuses on analyzing the belief in Thanh Hoang in the Southeast region of Vietnam not only as a folk religious phenomenon but also as a specific socio-cultural institution reflecting the needs for organization and stability of the community life of Vietnamese residents during their migration and settlement in the Southeast region. Based on fieldwork at two typical communal houses, Tan Lan communal house (Dong Nai Province) and Tan An communal house (Binh Duong Province), the author analyzes the typical functions of this belief from the functionalist approach of Radcliffe-Brown and Malinowski to clarify the prominent functions of the Thanh Hoang belief, including: This psychological function reflects the community’s reliance on the supernatural protection of Thanh Hoang deities as a source of spiritual reassurance; the community cohesion function, maintaining order, organizing festival activities, educating morality and shaping local cultural values, fostering village solidarity, and expressing a sense of origin

Capsule trigonousellipsoid, ca. 9 mm long, 6 mm thick (wings excluded), reddish-green when fresh; wings unequal, ca. 11 mm long, lateral wings ca. 2 mm wide, abaxial wing triangular, ca. 5 mm wide. Distribution and ecology:— Begonia minhaniae is only known from the type locality in Van Tran District. It grows on moist cliff faces in shady lower primary evergreen broad-leaved forests, elevation ca. 512 m. Etymology:— The species is named in honor of Ms. Minh An Hoang, the second daughter of the first author. She is always the first author’s motivation to research and find new species. Conservation status:— We assess B. minhaniae to be Endangered based on criteria ENC2a(i) (IUCN 2022). This species has only four known populations in one single location with the number of mature individuals being less than 100, all of the populations were in areas which have no formal legal protection (its distribution overlapping the Mu Cang Chai Protection Forest, but it is not included on any national protected areas system). In the areas, the most prominent threat to the new species is deforestation, along with other human activities such as such as farming from around the habitat, which means it is prone to the risk of extinction due to chance events. Notes:— Like Begonia phouchomvoyensis Lanors., Lamxay & Souvann. (Lanorsavanh et al., 2020), this new species belongs to sect. Platycentrum. The two share several characters including rhizomatous habit, hairy petioles and abaxial lamina, 4-tepaled staminate flowers, pistillate flowers with 3 tepals and ovary 3 locules, but the new species can be distinguished by its stipule margin ciliate (vs. entire), the petiole densely subappressed yellowish-brown tomentose (vs. red villous), the leaf is glabrous on the adaxial surface (vs. strigose), the peduncle sparsely yellowish-brown tomentose (vs. red villous) and pedicel of pistillate flowers with two bracteoles (vs. bracteoles absent). A comparison of B. minhaniae and B. phouchomvoyensis is presented in Table 1. The character of pistillate flowers with unequal 3 tepals is uncommon in sect. Platycentrum, shared between B. phouchomvoyensis and B. minhaniae.Published as part of HOANG, THANH SON & LIN, CHE-WEI, 2022, Two new species, Begonia minhaniae and B. dieuanhiae (sect. Platycentrum, Begoniaceae), from northwestern Vietnam, pp. 87-96 in Phytotaxa 572 (1) on pages 87-88, DOI: 10.11646/phytotaxa.572.1.6, http://zenodo.org/record/730569
