Agricultural land use in Vietnam in the context of urbanization: status and policy implications
Authors: Huyen Phan Thi Thanh , Giang Pham Quy 
Published: March 2024

Abstract
This article generalizes the urbanization process and its impact on agricultural land use in Vietnam. The high rate of urbanization has led to a great demand for purchasing agricultural products, especially high-quality ones, and as a result, this affects agricultural development. On one hand, it offers new chances to expand the domestic market and to encourage exports. On the other hand, the conversion of agricultural land into non-agricultural land under accelerated urbanization leads to a large area of arable land being abandoned or polluted, consequently affecting food security and sustainable development. Therefore, to meet the people’s food needs in the context of urbanization, it is necessary to have proper solutions to improve the efficiency of agricultural land use, such as: implementing land laws aimed at developing agricultural production in the direction of large-scale, concentrated commodities; executing land-use planning, performing agricultural production planning towards specialized cultivation with a stable term to ensure profitable investment; boosting the restructuring of the agricultural sector; developing collective and cooperative economics in agriculture; having policies to support, forecast, and search for markets for consumption and the processing of agricultural products; creating a transparent land-use rights market.

Abstract
This paper investigates the dynamics of market synchronicity and International Financial Reporting Standards (IFRS) adoption in Africa. It seeks to determine whether or not IFRS is an augmentor or inhibitor of market synchronicity in Africa. This study is not only a foundational study that unfolds the dynamics of market synchronicity and IFRS adoption in Africa but also extends the scope of synchronicity from firm-level assessment to country-level market synchronicity. It is one of the few studies which have shifted the literature on synchronicity from one largely limited to firm-level synchronicity to country-level synchronicity through analyses of cross-border market synchronisation. It employs Dynamic Ordinary Least Square (DOLS) and Generalised Method of Moments (GMM) to investigate the market synchronicity-IFRS nexus. The study uses monthly data from March 2005 to November 2021 in five African markets: Botswana, Ghana, Namibia, Nigeria, and South Africa generating 1005 observations in an 18-year data span. The paper reveals a significant negative consequence of IFRS on market synchronicity. Thus, IFRS exhibits an inhibition role in market synchronicity (reduces synchronicity) and improves price informativeness. A decreasing pattern was also observed immediately after IFRS was adopted by the stock markets and persisted for about five years. It implies that the price informativeness of stock markets through IFRS makes them good candidates for intra-Africa portfolio diversification due to reduced investors’ risk exposure to market synchronicity.

Brothers under the Skin. The Portrait of Sir Arthur Hopton and his Secretary by Jacob van Oost
Authors: Sanzsalazar Jahel 
Published: March 2024

Amongst the most interesting and controversial paintings of American Museums, the impressive Portrait of Sir Arthur Hopton and a Secretary (Dallas, Meadows Museum) remains labelled as ‘Anonymous’ despite several attempts to identify its author. The work indeed has a long history of attributions, mostly to painters from the 17th century Spanish School, none of which proved convincing enough. When Matías Díaz Padrón proposed the Flemish painter Jacob van Oost the Elder as the possible author of the portrait, although solidly based on compelling stylistic considerations, scholars remained sceptical due to the lack of evidence of the possible contact between the sitter and the painter. The present article provides substantial new arguments to link Sir Arthur Hopton to Flanders, and more particularly to Bruges, Van Oost’s native city. Moreover, a closer look at the painting allows for an opportunity to question the assumed date of the portrait, 1641, considering 1649 instead. In this scenario, the sitter’s nephew, Sir Ralph Hopton is revealed as a key figure: his potential involvement in the commission and conception of the work providing answers to several questions that remained unexplained. Finally, an unnoticed inscription in the canvas possibly reveals much more.Resumen: Entre las pinturas más controvertidas de los museos norteamericanos, el imponente Retrato de Sir Arthur Hopton y su secretario (Dallas, Meadows Museum), continúa como “Anónimo” a pesar de las múltiples tentativas de encontrarle autor. Cuenta, en efecto, con un largo historial de atribuciones, mayoritariamente a la escuela española del siglo XVII, ninguna lo suficientemente convincente. Cuando Matías Díaz Padrón propuso al flamenco Jacob van Oost el Viejo como posible autor del retrato, a pesar de sus sólidas y convincentes consideraciones estilísticas, los estudiosos se mostraron escépticos, a falta de pruebas de un posible contacto entre el retratado y el pintor. El presente artículo aporta nuevos elementos que vinculan a Sir Arthur Hopton con Flandes de manera significativa y, más precisamente, con Brujas, la ciudad natal de Van Oost. De otra parte, una observación más detenida de la pintura conduce a cuestionar la fecha de 1641 hasta ahora asumida para el retrato, optando en su lugar por 1649. En este cruce de circunstancias, el sobrino del retratado, Sir Ralph Hopton, emerge como figura clave; su vinculación potencial con el encargo y la concepción de la pintura daría respuesta a varios interrogantes. Por último, una inscripción inadvertida podría desvelar algo más.

The first and second collisions of three atoms after departure from the surface of the condensed phase
Authors: Желтов С.А. , Плетнев Л.В. 
Published: March 2024

Важную роль в процессах массопереноса играет взаимодействие молекул с поверхностями систем и с поверхностью конденсированной фазы при испарении вещества. Интенсивность испарения вещества зависит от температуры поверхности, т.е. от количества молекул, вылетающих с единицы поверхности. Значительную роль в процессе испарения играют первые и вторые столкновения молекул, вылетающие с поверхности, которые образуют слой Кнудсена над поверхностью. В представленной работе, на основе модели жестких сфер, проведен анализ плотностей распределений столкновений трех атомов, одновременно вылетающих с поверхности конденсированной фазы во времени и в пространстве. Получены плотности распределений первых и вторых столкновений атомов во времени и в пространстве в зависимости от температуры поверхности и размера области вылета. Компьютерные эксперименты проводились методом Монте-Карло. Для получения результатов был разработан параллельный алгоритм, адаптированный к расчетам на графических процессорах с технологией CUDA.
An important role in the processes of heat and mass transfer is played by the interaction of molecules with the surfaces of systems and with the surface of the condensed phase during the evaporation of substance. The intensity of evaporation of the substance depends on the surface temperature, i.e. on the number of molecules departing from a unit of the surface. A significant role in the evaporation process is played by the first and second collisions of molecules departing from the surface, which form a Knudsen layer above the surface. In the presented work, the analysis of the collision densities of three atoms, simultaneously escaping from the surface of the condensed phase in time and space, has been carried out on the basis of the model of rigid spheres. The distribution of the first density and the second collision of atoms in time and space, depending on the surface temperature and the size of the departure area, have been obtained. Computer experiments were carried out using the Monte Carlo method. To obtain the results, a parallel algorithm adapted to calculations on graphics processors with CUDA technology was developed.
