This paper aims to develop a parallel fast neighbor search method and communication strategy for particle-based methods with adaptive smoothing-length on distributed-memory computing systems.

With a multi-resolution-based hierarchical data structure, the parallel neighbor search method is developed to detect and construct ghost buffer particles, i.e. neighboring particles on remote processor nodes. To migrate ghost buffer particles among processor nodes, an undirected graph is established to characterize the sparse data communication relation and is dynamically recomposed. By the introduction of an edge coloring algorithm from graph theory, the complex sparse data exchange can be accomplished within optimized frequency. For each communication substep, only efficient nonblocking point-to-point communication is involved.

Two demonstration scenarios are considered: fluid dynamics based on smoothed-particle hydrodynamics with adaptive smoothing-length and a recently proposed physics-motivated partitioning method [Fu et al., JCP 341 (2017): 447-473]. Several new concepts are introduced to recast the partitioning method into a parallel version. A set of numerical experiments is conducted to demonstrate the performance and potential of the proposed parallel algorithms.

The proposed methods are simple to implement in large-scale parallel environment and can handle particle simulations with arbitrarily varying smoothing-lengths. The implemented smoothed-particle hydrodynamics solver has good parallel performance, suggesting the potential for other scientific applications.

Despite the fact that online is predicted to become the major channel for luxury purchases by 2025, there is scant literature related to online luxury buying behavior, mainly in the context of Generation Y (Gen Y) consumers in emerging societies like India. Therefore, the primary objective of this study is to empirically test the theoretical framework developed to assess the factors influencing luxury consumers' online shopping behavior based on the stimulus-organism-response model and technology acceptance model (TAM).

Data were collected from 233 Gen Y luxury consumers in India via purposive sampling method. The study used AMOS and PROCESS SPSS Macro to establish the overall fit of the measurement model and examine the hypotheses.

The findings revealed that perceived usefulness of buying online, perceived ease of buying online, economic benefit and webstore quality have significant impact on online luxury purchase intention. The perceived experiential values and perceived functional values mediate the influence of antecedent variables on online luxury purchase intention. Bandwagon luxury consumption behavior (BLCB) moderates the relationship between perceived functional values and online purchase intention.

This is one of the pioneer studies conducted to understand the influence of BLCB on value–intention relationship in online space among Gen Y luxury consumers. This study will help luxury retailers to create targeted strategies for this segment.

Recently, internet has turned out to be the fastest growing channel for luxury sales. Surprisingly, very few studies have focused on understanding the major drivers behind online luxury goods consumption, particularly in the emerging market context. Therefore, the key objectives of this study are to, first, develop a framework to understand factors affecting consumers' intention to purchase luxury fashion goods online. Second, measure the moderating effect of perceived risk and web atmospherics on the relationship between attitude toward buying luxury fashion goods online and online luxury purchase intention.

Data were collected through structured questionnaires from a sample of 250 luxury fashion consumers in India. Collected data were analyzed through confirmatory factor analysis (CFA) and Hayes Process macro in SPSS.

Study findings indicate that perceived usefulness, perceived ease of use, perceived enjoyment and price consciousness have a direct as well as an indirect relationship via attitude on online luxury purchase intention. The results also revealed that web atmospherics moderate the relationship between attitude toward buying luxury fashion goods online and online luxury purchase intention.

This is one of the first studies that explores the moderating role of perceived risk and web atmospherics in the context of luxury market. It will help luxury marketers to develop appropriate strategies for selling luxury goods online in emerging markets like India.

While the architect members of the Adam family have been subjected to considerable scrutiny over the years, architectural historians seem to have overlooked the information to be gleaned from the 1883 catalogue of the Blair Adam library, a copy of which is held in the National Library of Scotland. Of course a catalogue printed almost a hundred years after the death of the last of the architects in the family is hardly a totally reliable guide. Nevertheless, if used with care and in association with other surviving evidence, it can shed additional light on a number of aspects of Adam biography.

Although fewer than 150 years have passed since Jacques Daguerre perfected the first photographic image in 1839, the flood of evolving equipment and applications has already generated a broad and richly varied field. Simultaneously one of the youngest arts and one of the newest technologies, photography is now used in medical research, space exploration, criminal investigations, agricultural production, design of industrial machinery, ad infinitum. At one extreme, it records family life and supplies the surest method of identification on drivers' licenses. At the other end of the spectrum, photography (once denounced in haute couture) has within the past five years not only become an “acceptable” art form, but has assumed centerstage in museums and exhibits throughout the United States and Europe.

The following classified, descriptive list of titles is intended to provide reference librarians with a current checklist of new reference books, and is designed to supplement the RSR review column, “Recent Reference Books,” by Frances Neel Cheney. “Reference Books in Print” includes all additional books received prior to the inclusion deadline established for this issue. Appearance in this column does not preclude a later review in RSR. Publishers are urged to send a copy of all new reference books directly to RSR as soon as published, for immediate listing in “Reference Books in Print.” The prevailing policy of including all reference books received has temporarily allowed the listing of titles with imprints older than two years; with increased receipt of more current titles from a longer list of publishers, this policy will soon be discontinued (with the exception of older books newly acquired for distribution by another publisher). An additional copy of any title specifically requested by Mrs. Cheney should be sent to her for review. A decision to review titles appearing in the present column will then be made by Mrs. Cheney at her own discretion.
