Abstract
Purpose
This paper seeks to explore the necessity to incorporate technology as a key component in studying business operations of industrial entities.
Design/methodology/approach
Reviews of key management theories that shaped organization‐centric and process‐centric views in industrial management research are conducted. The paper then identifies the limitations of these two schools of thinking and develops a technology‐centric framework that integrates technology, organization, and process in general. A series of case studies that apply the framework at multiple levels of observations are presented. The research concludes with theoretical and managerial implications.
Findings
This paper presents a “trinity” framework that includes three core constructs that can simultaneously develop into variants. Technology as a holistic concept must be taken into consideration when researchers or practitioners take a dynamic view to study business entities. A multi‐dimensional, technology‐centric framework acknowledges technology as the transformational resource and helps the practitioners and researchers to examine technology as potential facilitators for organizational operations.
Originality/value
A review of the cases found that technology, organizational structures, and business processes impact one another. Firms' actions are indicative that in today's technology‐intensive environment, organizational structures and business processes need to be developed or modified in coordination with technological development. In doing so, organizations will gain the potential to harvest benefits from technology‐organization‐process integration.

Abstract
Purpose
Honeycomb cellular structures exhibit unique mechanical properties such as high specific strength, high specific stiffness, high energy absorption and good thermal and acoustic performance. This paper aims to use numerical modeling to investigate the effective elastic moduli, in-plane and out-of-plane, for thick-walled honeycombs manufactured using selective laser melting (SLM).
Design/methodology/approach
Theoretical predictions were performed using homogenization on a sample scale domain equivalent to the as-manufactured dimensions. A Renishaw AM 250 machine was used to manufacture hexagonal honeycomb samples with wall thicknesses of 0.2 to 0.5 mm and a cell size of 3.97 mm using 304 L steel powder. The SLM-manufactured honeycombs and cylindrical test coupons were tested using flatwise and edgewise compression. Three-dimensional finite element and strain energy homogenization were conducted to determine the effective elastic properties, which were validated by the current experimental outcomes and compared to analytical models from the literature.
Findings
Good agreement was found between the results of the effective Young’s moduli ratios numerical modeling and experimental observations. In-plane effective elastic moduli were found to be more sensitive to geometrical irregularity compared to out-of-plane effective moduli, which was confirmed by the analytical models. Also, it was concluded that thick-walled SLM manufactured honeycombs have bending-dominated in-plane compressive behavior and a stretch-dominated out-of-plane compressive behavior, which matched well with the simulation and numerical models predictions.
Originality/value
This work uses three-dimensional finite element and strain energy homogenization to evaluate the effective moduli of SLM manufactured honeycombs.

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
Purpose
In additive manufacturing (AM), “complexity for free” is often cited as a major technological benefit. This generalized view has been found inaccurate by several authors dealing with the evaluation of part complexity. However, the term “complexity” is not defined uniformly. The reasons for this are the various AM processes and different evaluation factors used by the respective authors. This is critical because build time heavily depends on the impact of complexity on the additive process through the processing tool (point-to-point-, line- and mask-based) defining competitiveness. This study aims to define appropriate complexity indicators and evaluate the impact on productivity of PBF-LB/P (laser sintering).
Design/methodology/approach
An assessment methodology for geometric complexity is developed for point-to-point-based processes using the PBF-LB/P process. First, an overview of part characteristics and their interrelationships with the generation process is provided. In this way, relevant factors, e.g. part volume and perimeter length, are identified. Subsequently, these are used to create a metric to select and manufacture test samples to quantify the impact on build time.
Findings
The results indicate a strong impact of geometrical complexity on build time and build-up rate. Consequently, optimizing the geometry in the early design stage and adjusting process parameters during production planning allow to influence the build-up rate.
Originality/value
This paper demonstrates the effects of geometric complexity using manufacturing jobs. As a result, the suitability of existing methods and KPIs is shown to be insufficient. Hence, meaningful indicators for laser sintering, such as contour length vs hatch length, contour length vs part volume and number of hatches vs part volume, are defined and verified.

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
Librarians have been urged to emphasize social justice and human rights issues in their library mission, but they may find themselves challenged to provide additional services, such as access to legal information for those who cannot afford an attorney. Social justice services in libraries are seldom adequately funded and providing services in this area is labor intensive. In addition, there is an emotional intensity in library services for social justice that is often not considered in the initial enthusiasm of providing services in this area. Yet there seems to be no limit to the need. An interesting and useful perspective on how a public agency such as a library responds in circumstances of limited resources and unlimited demand can be found in the book Street-Level Bureaucracy: Dilemmas of the Individual in Public Service, by Michael Lipsky. In this perspective, lower level civil servants who interact directly with members of the general public exercise a level of discretion in the amount of services provided and how those services are administered. This chapter explores how this can generate tensions between more traditional library bureaucracy and social justice services, such as providing public access to justice resources in law libraries. However, the “street-level” response is evolving into a sustainability perspective as librarians embrace a more social justice–oriented outlook in library service planning.

Abstract
Depending on the research approach one uses, the development of particular bodies of knowledge over time is the result of a combination of agency, chance, opportunity, patronage, power, or structure. This particular account of the development of geographies of tourism stresses its place as understood within the context of different approaches, different research behaviors and foci, and its location within the wider research community and society. The chapter charts the development of different epistemological, methodological, and theoretical traditions over time, their rise and fall, and, in some cases, rediscovery. The chapter concludes that the marketization of academic production will have an increasingly important influence on the nature and direction of tourism geographies.

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.

Abstract
In order to manage library or information functions you must be able to persuasively communicate with your management. To accomplish this, you must communicate in the language of your management, marshalling trendy and persuasive points on your own behalf With that as a given, there has been a very heartening development over the last few years for library and information managers—a burgeoning management attention to information.
