Abstract
Vine is a Very Informal NEwsletter produced three or four times a year by the G6TI Library Automation Projects' Information Officer (based at Southampton University Library) and issued on request to interested librarians, systems staff and library college lecturers. Its object is to provide an up‐to‐date picture of the activities of the Projects and occasionally to feature other automation work of special interest not already reported elsewhere.

Abstract
This paper investigates the change in informational spillover between nine Asian capital markets and the United States as a result of the 1997–98 financial meltdown in Asia. Our study period extends from about three years prior to the start of the crises on July 2, 1997 to one year after this date. We conduct spillover studies on daily stock market index prices and returns to determine the changes in market interdependence. Our results indicate a considerable increase in cross‐border cointegration during the crisis. Dramatic shifts in predictability and volatility spillovers are observed in most Asian countries as a result of the Asian financial crisis, providing evidence of an increase of interdependence between Asian countries, and thus suggesting contagion. We observe a strong interdependence with the US markets before the crisis, which persists during the crisis. We also show that Hong Kong and Korea have emerged as the most dominant influences in the region during the Asian financial crisis.
Abstract

Purpose
Additive manufacturing (AM) or solid freeform fabrication (SFF) technique is extensively used to produce intrinsic 3D structures with high accuracy. Its significant contributions in the field of tissue engineering (TE) have significantly increased in the recent years. TE is used to regenerate or repair impaired tissues which are caused by trauma, disease and injury in human body. There are a number of novel materials such as polymers, ceramics and composites, which possess immense potential for production of scaffolds. However, the major challenge is in developing those bioactive and patient-specific scaffolds, which have a required controlled design like pore architecture with good interconnectivity, optimized porosity and microstructure. Such design not only supports cell proliferation but also promotes good adhesion and differentiation. However, the traditional techniques fail to fulfill all the required specific properties in tissue scaffold. The purpose of this study is to report the review on AM techniques for the fabrication of TE scaffolds.
Design/methodology/approach
The present review paper provides a detailed analysis of the widely used AM techniques to construct tissue scaffolds using stereolithography (SLA), selective laser sintering (SLS), fused deposition modeling (FDM), binder jetting (BJ) and advanced or hybrid additive manufacturing methods.
Findings
Subsequently, this study also focuses on understanding the concepts of TE scaffolds and their characteristics, working principle of scaffolds fabrication process. Besides this, mechanical properties, characteristics of microstructure, in vitro and in vivo analysis of the fabricated scaffolds have also been discussed in detail.
Originality/value
The review paper highlights the way forward in the area of additive manufacturing applications in TE field by following a systematic review methodology.

Abstract
HOW much is lightness worth? The question is one upon which many engineers have formed their own opinions. Their conclusions range in written expression from the epigrammatic observation of Major Green, of the British Armstrong Siddeley Company, that he would “spend a pound to save a pound any time,” to an estimate of $40 per pound offered by a well‐known American metallurgist. We are going in search of a definite answer, with arithmetic taking the place of speculation.

Abstract
Purpose
The objective of the paper is to examine the effect of brand name and promotion on consumers' perceived value, store image, and purchase intention.
Design/methodology/approach
An experiment with a 2×2 (well known versus unknown brand name, promotion versus no promotion) between‐subjects factorial design was conducted and completed by 392 college students.
Findings
Brand name had a positive effect on consumers' perceived store image and promotion positively influenced consumers' perceived value. There were positive relationships among perceived value, store image and behavioral intention.
Research limitations/implications
Since participants were primarily female college students at a Midwestern university in the USA, the results of the study cannot be generalized to the general population of college students.
Practical implications
Online retailers should consider the importance of enhancing their brand familiarity in terms of creating positive store image. Effective sales promotions could be used as a reward for loyal consumers and to attract more new consumers.
Originality/value
In spite of prevailing sales promotions and brand names in online shopping, little research has addressed the effect of promotion and brand name on online apparel shoppers' responses. The empirical evidence of this study will contribute to the literature in online apparel retailing fields.

Abstract
Purpose
This paper aims to review the advances in additive manufactured (AM) scaffolds for bone tissue engineering (TE). A discussion on the state of the art and future trends of bone TE scaffolds have been done in terms of design, material and different AM technologies.
Design/methodology/approach
Different structural features and materials used for bone TE scaffolds are evaluated along with the discussion on the potential and limitations of different AM scaffolds. The latest research to improve the biocompatibility of the AM scaffolds is also discussed.
Findings
The discussion gives a clear understanding on the recent research trend in bone TE AM scaffolds.
Originality/value
The information available here would be useful for the researchers working on AM scaffolds to get a quick overview on the recent research trends and/or future direction to work on AM bone TE scaffolds.

Abstract
Successes in scaffold guided tissue engineering require scaffolds to have specific macroscopic geometries and internal architectures to provide the needed biological and biophysical functions. Freeform fabrication provides an effective process tool to manufacture many advanced scaffolds with designed properties. This paper reports our recent study on using a novel precision extruding deposition (PED) process technique to directly fabricate cellular poly‐ε_rm;‐caprolactone (PCL) scaffolds. Scaffolds with a controlled pore size of 250 μm and designed structural orientations were fabricated.

Abstract
1. BLCMP has just published a document describing the Project's use of the MARC format:‐ BLCMP MARC Manual: input procedures for monographs cataloguing. With supplement: music and sound recordings. BLCMP, 1972. £1.50. ISBN 0 903154 03X. This is primarily an instruction manual for BLCMP staff but is likely to be of interest both to other MARC users and to those contemplating automation of cataloguing. The manual parallels the BNB MARC Documentation Service publication no.5; it describes the format for cataloguing monographs as it is applied by BLCMP, and shows how, on occasion, this differs from BNB practice. The format in use for serials cataloguing has already been described in MASS Working Paper no.1, 1970. In the United States the tendency appears to be for the Library of Congress to develop different, not necessarily compatible, formats for different media. In the UK, however, it is regarded as important, largely for economy of program development, that all media should conform to a basic format with extensions to it for special media. This is the case with the BLCMP cataloguing format for music and sound recordings and serials.
