Abstract
Rapid Prototyping (RP) technologies provide the ability to fabricate initial prototypes from various model materials. Stratasys Fused Deposition Modeling (FDM) is a typical RP process that can fabricate prototypes out of ABS plastic. To predict the mechanical behavior of FDM parts, it is critical to understand the material properties of the raw FDM process material, and the effect that FDM build parameters have on anisotropic material properties. This paper characterizes the properties of ABS parts fabricated by the FDM 1650. Using a Design of Experiment (DOE) approach, the process parameters of FDM, such as raster orientation, air gap, bead width, color, and model temperature were examined. Tensile strengths and compressive strengths of directionally fabricated specimens were measured and compared with injection molded FDM ABS P400 material. For the FDM parts made with a 0.003 inch overlap between roads, the typical tensile strength ranged between 65 and 72 percent of the strength of injection molded ABS P400. The compressive strength ranged from 80 to 90 percent of the injection molded FDM ABS. Several build rules for designing FDM parts were formulated based on experimental results.

Abstract
The impact rapid prototyping (RP) can have on the design process and the product development process as a whole is demonstrated in this paper. The speed and flexibility of RP technologies decreased the overall time to complete the new product. This also ensured that the final mechanical enclosure of the new handheld video game incorporated the ergonomic design features that users desired.

IT is fitting that a new series of this magazine should be introduced by some reflections on the whole question of book selection, both for the general public and libraries.

Abstract
Rough sex - or what is referred to in this chapter as ‘consensual aggression and violence during sex’ (CAVS) - has been the focus, in the United Kingdom and internationally, of some attention and also concern. The latter derives especially from criminal justice proceedings relating to incidents where male suspects have seriously or fatally injured another individual, usually female, and then made claims - that are widely believed to be false - that the incident was a ‘sex game gone wrong’. Despite the importance of this subject, there is little or no understanding of the state of knowledge surrounding CAVS. This chapter outlines results from what is believed to be the first scoping (literature) review of CAVS in the general population. The review was based largely on a search, during June and July 2021, of 15 major databases using 18 search terms, which was conducted in accordance with the JBI Manual for Evidence Synthesis. A total of 74 sources were identified. The research reviewed covered a quite large number and diverse range of areas in respect of CAVS, comprising: conceptualization; attitudes; extent; context, dynamics and nature; explanations; CAVS-related pornography; effects; alleged CAVS; policy and practice responses; methodological weaknesses; and future research needs. Overall, the review highlights two distinct perspectives on CAVS: in the first, individuals chose to take part in CAVS, which they like and enjoy; in the second, individuals, especially women and girls, have experiences of CAVS that are non-consensual or unwanted, and which they find upsetting, frightening or scary.

Abstract
Aim of the present monograph is the economic analysis of the role of MNEs regarding globalisation and digital economy and in parallel there is a reference and examination of some legal aspects concerning MNEs, cyberspace and e‐commerce as the means of expression of the digital economy. The whole effort of the author is focused on the examination of various aspects of MNEs and their impact upon globalisation and vice versa and how and if we are moving towards a global digital economy.

Abstract
The librarian and researcher have to be able to uncover specific articles in their areas of interest. This Bibliography is designed to help. Volume IV, like Volume III, contains features to help the reader to retrieve relevant literature from MCB University Press' considerable output. Each entry within has been indexed according to author(s) and the Fifth Edition of the SCIMP/SCAMP Thesaurus. The latter thus provides a full subject index to facilitate rapid retrieval. Each article or book is assigned its own unique number and this is used in both the subject and author index. This Volume indexes 29 journals indicating the depth, coverage and expansion of MCB's portfolio.

Abstract
In the last four years, since Volume I of this Bibliography first appeared, there has been an explosion of literature in all the main functional areas of business. This wealth of material poses problems for the researcher in management studies — and, of course, for the librarian: uncovering what has been written in any one area is not an easy task. This volume aims to help the librarian and the researcher overcome some of the immediate problems of identification of material. It is an annotated bibliography of management, drawing on the wide variety of literature produced by MCB University Press. Over the last four years, MCB University Press has produced an extensive range of books and serial publications covering most of the established and many of the developing areas of management. This volume, in conjunction with Volume I, provides a guide to all the material published so far.
