Strategic Group Formation in the Mekong Delta: The Development of a Modern Hydraulic Society

The lower Mekong Delta, one of the largest river deltas in Asia, is a landscape shaped by the waters of the Mekong River that flows, as last part of its long way from the Tibetan Plateau to the South Chinese Sea, through a dense river and canal network in the Southwest of Vietnam. People in this area are, traditionally, exposed to a water-shaped environment and have lived for generations in adaptation to their natural surrounding without much human interference into the complex natural hydraulic system of the delta. However, this has changed dramatically during recent decades when hydraulic management started to become a key issue for the development of the lower Mekong Delta constantly, in particular with respect to the agricultural sector, which is the backbone of the delta’s economy. After the Second Indochinese War ended in 1975 the delta started to shift from human adaption to human control, transforming itself into what Wittfogel has described as a hydraulic society. This was mainly due to the new socialist government’s policy of rapid agricultural extension and growing endeavours in hydraulic management for fostering irrigated rice production. By now, in many places of the delta hydraulic works such as additional canals, dykes and sluices have been set up, constructed for regulating water flows. Technical innovations in hydraulic management and agricultural production have not only had significant impact on the delta’s environment and ecology, but also have triggered social transformation, in particular the appearance of new social groups struggling for access to resources and power. This paper intends to analyzes recent trends of social development and water management in the Mekong Delta from a scientific approach that is based on two social theories, firstly “strategic group analysis”, and secondly selected core aspects of Wittfogel’s social theory of “hydraulic society”. By presenting recently collected data, it is illustrated how the Mekong Delta has been transformed into a modern hydraulic society, in which certain strategic groups emerged as a consequence of growing activities in hydraulic management and agricultural-based economic growth. More specifically, the paper aims to give an overview of strategic group development in the delta by putting a strong focus on the process of forming a state bureaucracy of hydraulic management and the appearance of hydraulic construction companies as its clients. The paper shows how the strategic alliance between both groups has increased the chances for mutually appropriating government funds spent on hydraulic works and how this has caused ecologically and socially far-reaching impacts for the Mekong Delta.Vietnam; Mekong Delta; strategic groups; hydraulic society; social transformation and power; water management; hydraulic bureaucracy; economic development

Chemically triggered formation of two-dimensional epitaxial quantum dot superlattices

Two dimensional superlattices of epitaxially connected quantum dots enable size-quantization effects to be combined with high charge carrier mobilities, an essential prerequisite for highly performing QD devices based on charge transport. Here, we demonstrate that surface active additives known to restore nanocrystal stoichiometry can trigger the formation of epitaxial superlattices of PbSe and PbS quantum dots. More specifically, we show that both chalcogen-adding (sodium sulfide) and lead oleate displacing (amines) additives induce small area epitaxial superlattices of PbSe quantum dots. In the latter case, the amine basicity is a sensitive handle to tune the superlattice symmetry, with strong and weak bases yielding pseudohexagonal or quasi-square lattices, respectively. Through density functional theory calculations and in situ titrations monitored by nuclear magnetic resonance spectroscopy, we link this observation to the concomitantly different coordination enthalpy and ligand displacement potency of the amine. Next to that, an initial similar to 10% reduction of the initial ligand density prior to monolayer formation and addition of a mild, lead oleate displacing chemical trigger such as aniline proved key to induce square superlattices with long-range, square micrometer order; an effect that is the more pronounced the larger the quantum dots. Because the approach applies to PbS quantum dots as well, we conclude that it offers a reproducible and rational method for the formation of highly ordered epitaxial quantum dot superlattices

Assessing user experience of context-aware interfaces in a retail store

Context-awareness is becoming an essential functionality of mobile applications. However, it remains challenging to capture the contextual experience in innovation research, since early-stage technologies have not reached maturity to be implemented in a real-life context. Moreover, users have difficulty in evaluating implicit interactions with context-aware interfaces since imagination of users is limited. Assuming that context impacts user experience, virtual reality (VR) provides an untapped potential for the domain of innovation research. The aim of this study (in progress) is to investigate the potential of user tests in virtual reality (here virtual retail store) for human-computer interaction to better match the needs of users and designers. Initially, the mock-up has been implemented in a retail store with its context-awareness being simulated using the Wizard of Oz methodology (N = 18). This approach is found to be time-consuming and not sufficient for evaluating radical context-aware innovations
