The case study is carried out on a piece of gold brocade lined with handmade paper and used as mounting textile for historic Chinese paintings. This “light brown brocade with gold wefts and a lotus pattern” (specifically, a preserved sample of a precious ancient silk mounting textile taken from a piece of the deceased Master Chang Dai-Chien’s collection, and provided by Professor Sun Jia-Cin, Master Chang’s last disciple) is decorated with a gold lotus pattern against a background that is light brown in color. The ground warps and the gold patterns are interconnected in a structure of one warp and two wefts (light brown wefts and gold weft threads). The weave for the ground structure can be identified as a warp-faced 2/1 right twill with light brown warps and flossy light brown wefts. Flat strips of gold threads are applied as continuous supplementary wefts, and woven into the design in the mode of a 1/2 right twill weft backed weave. The ground weft is connected by warp to the gold weft in a 2:1 ratio called Ban-Yua. Based on an analysis by Fourier transform infrared spectroscopy (FTIR) and a combustion method for textile fiber analysis, both the ground warp and the weft are made of silk. In addition, according to the result given by energy dispersive X-ray spectroscopy (EDS), the primary material of the gilded weft is gold. The paper lining on the back of the gold strip is made of natural fibers, according to the result from a scanning electron microscope (SEM) and an FTIR examination. Based on the shape of the lotus motif, it is estimated that this gold brocade dates back to the Ming Dynasty period.

The purpose of this paper is to introduce an interpreting schema and semantic description framework for a collection of images of Xilankapu, a traditional Chinese form of embroidered fabric and brocade artwork.

First, the authors interpret the artwork of Xilankapu through Gillian Rose’s “four site” theory by presenting how the brocades were made, how the patterns of Xilankapu are classified and the geometrical abstraction of visual images. To further describe the images of this type of brocade, this paper presents semantic descriptions that include objective–non-objective relations and a multi-layered semantic framework. Furthermore, the authors developed corresponding methods for scanning, storage and indexing images for retrieval.

As exploratory research on describing, preserving and indexing images of Xilankapu in the context of the preservation of cultural heritage, the authors collected 1,000+ images of traditional Xilankapu, classifying and storing some of the images in a database. They developed an index schema that combines concept- and content-based approaches according to the proposed semantic description framework. They found that the framework can describe, store and preserve semantic and non-semantic information of the same image. They relate the findings of this paper to future research directions for the digital preservation of traditional cultural heritages.

The framework has been designed especially for brocade, and it needs to be extended to other types of cultural image.

The semantic description framework can describe connotative semantic information on Xilankapu. It can also assist the later information retrieval work in organizing implicit information about culturally related visual materials.

People have worked together since the beginnings of human time. Since then the forms of collaboration have barely changed. While a group of laborers building the pyramids of Egypt might seem to bear little resemblance to a team of machine operators working in a plant, they actually have much in common. Both groups are made up of people of similar backgrounds with clear loyalties and interests, interacting face-to-face to perform relatively well-defined tasks in pursuit of a shared goal.

The illegal backdating of stock options has been studied by economists and lawyers, but totally neglected by criminologists. We examine three cases in order to convey a sense of how backdating has played out in practice, and consider the results of empirical research that has been published on the subject. Traditional legal analyses, mostly by law students, have detailed the statutory history and standing of the law regarding stock options. Economic writings focus almost exclusively on structural features that may correlate with outcomes. The failure of financial writers to carefully distinguish between criminal and noncriminal backdating is in part a consequence of the limited theoretical interpretations in their field beyond cost–benefit analysis and rational choice calculations. Criminologists, while having a plethora of theoretical constructs that might be applied to backdating, generally have no training to allow them to comprehend the arcane elements of economic criminal behavior. We conclude that more multidisciplinary attention is necessary to overcome the current pigeonholing of research approaches that limits both understanding of illegally backdated stock options and effective policies designed to prevent it.

This chapter describes the change efforts and action research projects at a Dutch multinational which, over a period of 25 years, produced in one of its businesses a zigzag path toward collaborative leadership dynamics at the horizontal and vertical interfaces. The chapter also identifies the learning mechanisms that helped achieve this transformation. Changing the patterns at the vertical interfaces proved to be a most tricky, complex, and confusing operation. The data show that organizations need hierarchical interfaces between levels, but are hindered by the hierarchical leadership dynamics at these interfaces. The data furthermore show that competitive performance requires more than redesigning horizontal interfaces. A business can only respond with speed and flexibility to threats and opportunities in the external environment when the leadership dynamics at agility-critical vertical interfaces are also changed.

A comparison of the coverage provided by BIOSIS Previews (BP) and Medline databases was carried out by VOGIN, a group of professional searchers based in The Netherlands. The area chosen was clinical medicine, and the group looked at problems requiring diagnosis and treatment. The data provided by this study show that while it is more economical to use Medline, BP provides a greater degree of completeness and often provides an unexpectedly large amount of new information. A strong point of BP is its coverage of abstracts of books and meetings, which are either not provided or difficult to find in Medline.

The purpose of this paper is to explore query expansion via conceptual distance in thesaurus indexed collections

An extract of the National Museum of Science and Industry's collections database, indexed with the Getty Art and Architecture Thesaurus (AAT), was the dataset for the research. The system architecture and algorithms for semantic closeness and the matching function are outlined. Standalone and web interfaces are described and formative qualitative user studies are discussed. One user session is discussed in detail, together with a scenario based on a related public inquiry. Findings are set in context of the literature on thesaurus‐based query expansion. This paper discusses the potential of query expansion techniques using the semantic relationships in a faceted thesaurus.

Thesaurus‐assisted retrieval systems have potential for multi‐concept descriptors, permitting very precise queries and indexing. However, indexer and searcher may differ in terminology judgments and there may not be any exactly matching results. The integration of semantic closeness in the matching function permits ranked results for multi‐concept queries in thesaurus‐indexed applications. An in‐memory representation of the thesaurus semantic network allows a combination of automatic and interactive control of expansion and control of expansion on individual query terms.

The application of semantic expansion to browsing may be useful in interface options where thesaurus structure is hidden.

The objective of this research is to address issues that relate to the assembly of Sn/Ag/Cu bumped flip chips.

Flip chips bumped with Sn/Ag/Cu bumps were assembled onto different lead‐free surface finishes at lead‐free soldering temperatures. Sensitivity to fluxes, reflow profiles, pad finishes and pad designs were all investigated and the potential consequences for assembly yields were calculated numerically.

Soldering defects, such as incomplete wetting and collapse and poor self‐centring were observed in the assemblies. Defect levels were sensitive to contact pad metallurgy and flux type, but not to flux level and reflow profile within the ranges considered. Owing to a particularly robust substrate‐pad design, defects observed in this work were limited to incomplete wetting and collapse, as well as poor self‐centering.

The scope of this work is limited to the lead‐free fluxes available at the time of research. A switch to lead‐free solder alloys in flip chip assemblies raises concerns with respect to the compatibilities of materials and the quality of soldering that is achievable. While this may be less of an issue in the case of larger area array components, such as ball grid arrays and chip scale packages, it is more of a concern for applications that use flip chips due to the smaller size of the solder spheres. Assembly yields tend to become more sensitive to the reduced collapse of the joints. More work is essential to investigate the potential benefits of more active lead‐free fluxes, both no‐clean tacky and liquid fluxes, in reducing or eliminating soldering defects.

The paper offers insights into assembly issues with Sn/Ag/Cu bumped flip chips.

The most powerful and effective forces of hierarchizing are those that naturalize difference so that it is beyond dispute and something to be tacitly accepted. In the Classic Maya world, this “social speciation” was materialized and naturalized through a complex web of ritual practice, deity emulation, enhancement of body aesthetics, and the fabrication and possession of hypertrophic goods. The architecture of Classic Maya royal courts broke with an older Maya residential pattern of accretional construction filled with ancestral burials in order to materialize more effectively social difference, to provide space for exclusive ritual performance, and to showcase the highly valued and gendered labor of textile production. Such instruments of authority are “weapons of exclusion” that can be wielded to fend off assaults on hierarchy. From this perspective, informed by the ritual economy approach, the profound transformations of the 9th century in the Maya lowlands are considered an assault that was not defendable.
