How Network Strategies and Institutional Transitions Evolve in Asia

Abstract: This article contributes to the literature on network strategies and institutional transitions in emerging economies in Asia by identifying a realistic, intermediate phase between the early and late phases of institutional transitions suggested by Peng (2003). Focusing on the intermediate phase, we advance two arguments based on network strength and network content. First, in terms of network strength, we leverage earlier insights that networks can be classified as strong ties and weak ties. Consequently, we suggest that as institutional transitions unfold, strong-tie-based networks, instead of being phased out, are being transformed into weak-ties-based networks. Second, from a network content standpoint, we argue that the various scale and scope of institutional transitions shape the content of different networks which focus on business-to-government (B2G) ties and business-to-business (B2B) relationships. Our propositions delineate how different transitions of political and legal institutions affect the evolution of B2G and B2B networks. Overall, we suggest that networks not only differ in strength but also in content, and that their evolution is driven by the impact of different dimensions of institutional transitions governing B2G and B2B relationships.

On the role of surface diffusion in determining the shape or morphology of noble-metal nanocrystals

Abstract: Controlling the shape or morphology of metal nanocrystals is central to the realization of their many applications in catalysis, plasmonics, and electronics. In one of the approaches, the metal nanocrystals are grown from seeds of certain crystallinity through the addition of atomic species. In this case, manipulating the rates at which the atomic species are added onto different crystallographic planes of a seed has been actively explored to control the growth pattern of a seed and thereby the shape or morphology taken by the final product. Upon deposition, however, the adsorbed atoms (adatoms) may not stay at the same sites where the depositions occur. Instead, they can migrate to other sites on the seed owing to the involvement of surface diffusion, and this could lead to unexpected deviations from a desired growth pathway. Herein, we demonstrated that the growth pathway of a seed is indeed determined by the ratio between the rates for atom deposition and surface diffusion. Our result suggests that surface diffusion needs to be taken into account when controlling the shape or morphology of metal nanocrystals.

Therapeutic Hypothermia after Out-of-Hospital Cardiac Arrest in Children

Abstract: BackgroundTherapeutic hypothermia is recommended for comatose adults after witnessed out-of-hospital cardiac arrest, but data about this intervention in children are limited. MethodsWe conducted this trial of two targeted temperature interventions at 38 children's hospitals involving children who remained unconscious after out-of-hospital cardiac arrest. Within 6 hours after the return of circulation, comatose patients who were older than 2 days and younger than 18 years of age were randomly assigned to therapeutic hypothermia (target temperature, 33.0°C) or therapeutic normothermia (target temperature, 36.8°C). The primary efficacy outcome, survival at 12 months after cardiac arrest with a Vineland Adaptive Behavior Scales, second edition (VABS-II), score of 70 or higher (on a scale from 20 to 160, with higher scores indicating better function), was evaluated among patients with a VABS-II score of at least 70 before cardiac arrest. ResultsA total of 295 patients underwent randomization. Among the 260 pat...
