This chapter demonstrates how the process of decolonization and the ensuing separation of Vietnam into a northern and southern state as part of the Cold War in Asia led to different types of history-writing. In both Vietnamese regimes, the writing of history had to serve the state, and in both countries historians emphasized its political function. Whereas North Vietnam located itself in an East Asian and Marxist context, historians of South Vietnam positioned it within a Southeast Asian setting and took a determinedly anti-communist position. After 1986—over a decade after reunification—with past tensions now relaxed, the past could be revaluated more openly under a reformist Vietnamese government that now also permitted much greater interaction with foreign historians.

Abstract. Rainfall threshold determination is a pressing issue in the landslide scientific community. While major improvements have been made towards more reproducible techniques for the identification of triggering conditions for landsliding, the now well-established rainfall intensity or event-duration thresholds for landsliding suffer from several limitations. Here, we propose a new approach of the frequentist method for threshold definition based on satellite-derived antecedent rainfall estimates directly coupled with landslide susceptibility data. Adopting a bootstrap statistical technique for the identification of threshold uncertainties at different exceedance probability levels, it results in thresholds expressed as AR = (α±Δα)⋅S(β±Δβ), where AR is antecedent rainfall (mm), S is landslide susceptibility, α and β are scaling parameters, and Δα and Δβ are their uncertainties. The main improvements of this approach consist in (1) using spatially continuous satellite rainfall data, (2) giving equal weight to rainfall characteristics and ground susceptibility factors in the definition of spatially varying rainfall thresholds, (3) proposing an exponential antecedent rainfall function that involves past daily rainfall in the exponent to account for the different lasting effect of large versus small rainfall, (4) quantitatively exploiting the lower parts of the cloud of data points, most meaningful for threshold estimation, and (5) merging the uncertainty on landslide date with the fit uncertainty in a single error estimation. We apply our approach in the western branch of the East African Rift based on landslides that occurred between 2001 and 2018, satellite rainfall estimates from the Tropical Rainfall Measurement Mission Multi-satellite Precipitation Analysis (TMPA 3B42 RT), and the continental-scale map of landslide susceptibility of Broeckx et al. (2018) and provide the first regional rainfall thresholds for landsliding in tropical Africa.

AbstractCultural norms diverge substantially across societies, often within the same country. We propose and investigate a self-domestication/selective migration hypothesis, proposing that cultural differences along the individualism–collectivism dimension are driven by the out-migration of individualistic people from collectivist core regions of states to peripheral frontier areas, and that such patterns of historical migration are reflected even in the current distribution of cultural norms. Gaining independence in 939 CE after about a thousand years of Chinese colonization, historical Vietnam emerged in the region that is now north Vietnam with a collectivist social organization. From the eleventh to the eighteenth centuries, historical Vietnam gradually expanded its territory southward to the Mekong River Delta through repeated waves of conquest and migration. Using a nationwide household survey, a population census, and a lab-in-the-field experiment, we demonstrate that areas annexed earlier to historical Vietnam are currently more prone to collectivist norms, and that these cultural norms are embodied in individual beliefs. Relying on many historical accounts, together with various robustness checks, we argue that the southward out-migration of individualistic people during the eight centuries of the territorial expansion is an important driver, among many others, of these cultural differences.

The genus Morphostenophanes Pic, 1925 is redefined and revised. Seventeen new species and three new subspecies are described, including M. aenescens yelang Zhou, new subspecies, M. bannaensis Zhou, new species, M. brevigaster Zhou, new species, M. chongli Zhou, new species, M. crassus Zhou, new species, M. furvus Zhou, new species, M. furvus weishanus Zhou, new subspecies, M. gaoligongensis Zhou, new species, M. iridescens Zhou, new species, M. lincangensis Zhou, new species, M. linglong Zhou, new species, M. metallicus Zhou, new species, M. minor, Zhou, new species, M. planus Zhou, new species, M. purpurascens Zhou, new species, M. sinicus Zhou, new species, and M. yunnanus Zhou, new species from Yunnan, China; M. chongli glaber Zhou, new subspecies from Yunnan, China and North Vietnam; M. curvitibialis Zhou, new species from Guangxi, China, and M. luoxiaoshanus Zhou, new species from Hunan, Hubei and Jiangxi, China. M. birmanicus (Kaszab, 1980) is recorded from China (Yunnan) for the first time. M. papillatus Kaszab, 1941 is firstly recorded from Yunnan and Sichuan, China. Two poorly known species, M. aenescens Pic, 1925 and M. vietnamicus Kaszab, 1980 are redescribed. Male of M. atavus (Kaszab, 1960) is described in detail. Misidentifications of M. aenescens Pic. 1925 and M. atavus (Kaszab, 1960) in previous works are corrected. Six species groups are proposed. A species catalog, identification key and distributional maps for the genus are given.

The Relationship

This article analyses the relationship between vulnerable households and local authorities during floods using the concept of linking social capital. The analysis combines a narrow operationalisation that measures the stock of linking social capital in vulnerable communities, with a broader operationalisation that seeks to address the nature of linking social capital. The empirical data, collected across four provinces in Central and North Vietnam, suggests that while a substantial stock of social linking capital exists in the vulnerable communities concerned, the nature of the relationship between the communities and local authorities during floods is characterised by top-down linkages and limited community autonomy. These linkages appear to be susceptible to social inertia during times of stress. They also undermine the development and reproduction of strong bonding and bridging social capital.
