Abstract:
In the article introducing this special issue, we consider the prospects of cultural diffusionism. We show that diffusion is not a uniform phenomenon since it includes direct, partial, multi-layered, and reverse forms. The complex approach to diverse forms of diffusions is called by us the crossroads concept. It aligns with cultural relativism which examines cultural traits through diffusion and modification. In world-systems analysis, cultural diffusion is analyzed within the world-economy framework, rooted in the classical Marxism view of economic systems as foundational with culture as a su

AbstractDiffusion studies have rightly emphasized external ideas and resources that propel liberalization in the developing world. There remain two gaps: first, the literature has not covered the types of diffusers and the ways diasporas may shape liberalization in their homelands; second, it pays little attention to internal diffusion after national adoption within a country. This article explores the utility and conditions of diffusion by diasporas and examines the roles of diasporas and internal diffusion in China and India's FDI liberalization.

Abstract:
The diffusion behavior of Ti3+ along basal dislocations in sapphire has been investigated by SIMS technique. High-density unidirectional dislocations were introduced by the high-temperature mechanical deformation, and Ti3+ ions were subsequently diffused along the dislocations. The SIMS diffusion profiles clearly showed diffusion tail due to the short circuit diffusion along the dislocations called pipe diffusion. Lattice diffusion coefficient and pipe diffusion coefficient of Ti3+ at 1300°C were measured to be 1.0±0.2×10-19 [m2/sec] and 2.0±0.6× 10-13 [m2/sec], respectively.

Abstract:
Thermal-moisture analogy schemes for a moisture diffusion analysis are reviewed. Two schemes for practical applications are described using the governing equations of heat and mass diffusions: (1) direct analogy and (2) normalized analogy. The schemes are implemented to define valid domains of application. The results corroborate that the direct analogy is valid only for single-material systems, but the normalized analogy can be extended to multimaterial systems if thermal loading conditions are isothermal, spatially as well as temporally.

AbstractVirtually all studies of policy diffusion are based on statutory enactments by state legislatures. But a substantial number of medicalized marijuana laws were initiated through citizen initiatives and ratified by referenda (I&R). This case study suggests that the diffusion of laws adopted by I&R requires two modifications to the conventional model of policy diffusion. First, early policy adoptions must occur through direct democracy so that horizontal diffusion results when those past adoptions by the I&R process lead to future adoptions.

Abstract:
Text-guided diffusion models such as DALLE-2, Imagen, and Stable Diffusion are able to generate an effectively endless variety of images given only a short text prompt describing the desired image content. In many cases the images are of very high quality. However, these models often struggle to compose scenes containing several key objects such as characters in specified positional relationships. The missing capability to ``direct'' the placement of characters and objects both within and across images is crucial in storytelling, as recognized in the literature on film and animation theory. In

Abstract:
We present our research into the fabrication of fully three-dimensional metallic nanostructures using diffusion-assisted direct laser writing, a technique which employs quencher diffusion to fabricate structures with resolution beyond the diffraction limit. We have made dielectric 3D nanostructures by multiphoton polymerization using a metal-binding organic-inorganic hybrid material, and we covered them with silver using selective electroless plating. We have used this method to make spirals and woodpiles with 600 nm intralayer periodicity. The resulting photonic nanostructures have a smooth m

Abstract:
The degree of diffusion is an important index of aging asphalt regeneration process, and diffusion model can more direct regeneration of recycled asphalt pavement material is described. By comparing the different diffusion model, and a variety of different diffusion effect evaluation method, providing basic theoretical research for the regeneration agent in aging effect of diffusion asphalt.
