Abstract
Purpose
The purpose of this paper is to present Design Rules for additive manufacturing and a method for their development.
Design/methodology/approach
First, a process-independent method for the development of Design Rules was worked out. Therefore, geometrical standard elements and attributes that characterize the elements’ shapes have been defined. Next, the standard elements have been manufactured with different attribute values with Laser Sintering, Laser Melting and Fused Deposition Modeling, and their geometrical quality was examined. From the results, Design Rules for additive manufacturing were derived and summarized in a catalogue.
Findings
Due to the process independent method, Design Rules were developed that apply for the different considered additive manufacturing technologies equally. These Design Rules are completely function-independent and easily transferable to individual part designs.
Research limitations/implications
The developed Design Rules can only apply for the considered boundary conditions. To extend the Design Rules’ validity, their applicability should be proven for other boundary conditions.
Practical implications
The developed Design Rules practically support the design of technical parts. Additionally they can be used for training and teaching in the field of “design for additive manufacturing”.
Originality/value
The developed Design Rules constitute a first step toward general Design Rules for Additive Manufacturing. Thus, they might form a suitable basis for further scientific approaches, and the Design Rules can be used to set up teaching documentations for lessons and seminars.

Abstract
Globalisation is generally defined as the “denationalisation of clusters of political, economic, and social activities” that destabilize the ability of the sovereign State to control activities on its territory, due to the rising need to find solutions for universal problems, like the pollution of the environment, on an international level. Globalisation is a complex, forceful legal and social process that take place within an integrated whole with out regard to geographical boundaries. Globalisation thus differs from international activities, which arise between and among States, and it differs from multinational activities that occur in more than one nation‐State. This does not mean that countries are not involved in the sociolegal dynamics that those transboundary process trigger. In a sense, the movements triggered by global processes promote greater economic interdependence among countries. Globalisation can be traced back to the depression preceding World War II and globalisation at that time included spreading of the capitalist economic system as a means of getting access to extended markets. The first step was to create sufficient export surplus to maintain full employment in the capitalist world and secondly establishing a globalized economy where the planet would be united in peace and wealth. The idea of interdependence among quite separate and distinct countries is a very important part of talks on globalisation and a significant side of today’s global political economy.

Abstract
Purpose
The purpose of this paper is to explore the key features of fashion rental from a business model perspective with a focus on the role played by digital platforms.
Design/methodology/approach
A qualitative research design was used based on multiple case studies of three Italian fashion rental enterprises.
Findings
The findings reveal the key aspects characterizing fashion rental business models and the centrality of digital platforms in value creation, configuration and capture activities. The study also found that fashion rental platforms are likely to exhibit further successful development in the future.
Originality/value
The academic literature on fashion rental has been mainly focussed on examining consumers' motivations and concerns, paying little attention to the enterprise's viewpoint. To date, no previous study has examined fashion rental business models from the retailer's perspective. This paper is the first to explore the key components of fashion rental business models and how digital platforms influence them from the perspective of retailers. The originality of the study is further strengthened by the unique context of analysis, namely, Italy, a leading country for global fashion.

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
The purpose of this paper is to investigate the relationship between religious involvement and attitudinal (importance of helping others and of being socially active) and behavioral components of prosociality (volunteering, charitable giving, and blood donations) in Germany.
Design/methodology/approach
The empirical analyses are based on representative, longitudinal data from the German Socio-Economic Panel, which allows avoiding issues of reverse causality.
Findings
The results suggest for a moderate, positive link between individuals’ religious involvement as measured by church affiliation and church attendance and the prosociality aspects addressed. Despite the historic divide in religion, the results in West and East Germany do not differ substantially in terms of the underlying mechanisms.
Originality/value
The paper complements the growing literature from experimental economics on the relationship between individuals’ religiosity and their prosociality. Based on representative longitudinal data, it contributes by providing evidence for Germany for which there is barely any insight yet and by addressing a wider range of attitudinal and (self-reported) behavioral components of prosociality.

Abstract
IT is evident from the numerous press cuttings which are reaching us, that we are once more afflicted with one of those periodical visitations of antagonism to Public Libraries, which occasionally assume epidemic form as the result of a succession of library opening ceremonies, or a rush of Carnegie gifts. Let a new library building be opened, or an old one celebrate its jubilee, or let Lord Avebury regale us with his statistics of crime‐diminution and Public Libraries, and immediately we have the same old, never‐ending flood of articles, papers and speeches to prove that Public Libraries are not what their original promoters intended, and that they simply exist for the purpose of circulating American “Penny Bloods.” We have had this same chorus, with variations, at regular intervals during the past twenty years, and it is amazing to find old‐established newspapers, and gentlemen of wide reading and knowledge, treating the theme as a novelty. One of the latest gladiators to enter the arena against Public Libraries, is Mr. J. Churton Collins, who contributes a forcible and able article, on “Free Libraries, their Functions and Opportunities,” to the Nineteenth Century for June, 1903. Were we not assured by its benevolent tone that Mr. Collins seeks only the betterment of Public Libraries, we should be very much disposed to resent some of the conclusions at which he has arrived, by accepting erroneous and misleading information. As a matter of fact, we heartily endorse most of Mr. Collins' ideas, though on very different grounds, and feel delighted to find in him an able exponent of what we have striven for five years to establish, namely, that Public Libraries will never be improved till they are better financed and better staffed.

Abstract
THE CATEGORICAL TABLES of the S.C. which are used entirely for the sub‐division of subjects have only been criticized for two reasons, and neither is very serious. It has been said that in many cases they make the notation too cumbrous and the numbers too long; and someone has objected to these tables for including subjects which are already in the main schedules. A lengthy symbol is almost inseparable from minute classification, because it is impossible without enormously increasing the main tables to provide for the many forms and standpoints which require expressing if an attempt is to be made to get right up to the specific subject. An example of enormous expansion will be found in the uncompleted Library of Congress Classification, in which no fewer than 7,079 numbers are used for music, a subject which in the S.C. is even more fully detailed in 332 numbers. For instance, there is no place in the Congressional scheme for the viol family of instruments, in connection with which there is a very large literature, so that, in spite of its great array of numbers, it appears that it is possible to miss important headings even in the most ambitious scheme. This inflation is caused by the constant repetition of forms, localities, and other categories, which in the S.C. are expressed once and for all in separate tables, by numbers which always mean the same thing. Thus:—

Abstract
THE pages of the Library World have at all times been open to receive the opinions of every side, on all questions of library policy, and we believe that it can be fairly claimed that no other English professional journal can show a greater record of catholicity and freedom from prejudice. Just recently we have published three articles in succession, which plead for, or advocate, some method of mitigating what the writers term the “Fiction Nuisance,” and one result of our complaisance may be witnessed in the stir which has been caused in journalistic quarters, over the alleged shortcomings of Public Libraries, and their scandalous distribution of nothing but fiction! It is argued, with some justice, that, if librarians are so quick to admit the existence of a fiction nuisance, then the case must be very serious indeed; and that it is regarded in this light may be gathered from the article on “Free Libraries,” by Mr. J. Churton Collins, in the June Nineteenth Century. For some reason or another, best known, no doubt, to themselves, certain librarians are always ready to join in the hue and cry against Public Libraries, and to lend the sanction of their authority to the general execration of fiction reading, thus giving a weapon to the enemy which is promptly used to thrash municipal libraries into a pulp. For months past this outcry against libraries has been going on, and there cannot be a single doubt that it has been stimulated by, if it did not originate in, the injudicious apologies for high fiction percentages in some library reports, and the publication of articles by librarians who admit too much, without giving substantial grounds for their conclusions. We are unable to say whether such apologies and articles are dictated by the weak, but human, desire to side with the majority, but there can be no doubt as to their harmful tendency and the evil they are causing all over the country. It is time, therefore, that the other, and, we believe, true side of the question should be put forward, and we propose to devote a series of articles to show that the charges made against Public Libraries of being nothing but huge engines for the distribution of fiction, mostly bad in tone and quality, are either gross misrepresentations, or exaggerations capable of explanation, and justification. As an introduction to this series, we have obtained permission from Mr. Thomas Greenwood, to use the greater part of the paper entitled, “The Great Fiction Question,” which is printed in Greenwoods Library Year Book, 1897, and is now becoming scarce and difficult to procure, owing to the book being out‐of‐print; like the later Year Book of 1900–1901. This paper is a vigorous, fair, and able statement of the case for fiction, which has not received the amount of attention it deserves, and we think it will be performing a service to librarians if we reprint it as a preliminary to our own proposed examination of the question of Fiction Reading in Public Libraries:

Abstract
IN his admirable survey of library methods and problems in Great Britain, read—unfortunately by proxy—at the St. Louis meeting of the American Library Association, which the author of this paper had the pleasure of hearing, Mr. Bond, in writing of open access, was courageous enough to say that the system in question was the system of the future. It is true that he put that future a long way off, but it is none the less creditable to Mr. Bond's fairness and foresight that he recognises and admits that some time the system of shelf access—perhaps a better term than open access—is bound to prevail, and become the rule rather than the exception in the library administration of this country. One has therefore a shrewd suspicion that much of the fierceness with which the system and the personalities of those who have adopted and approved it, have been assailed, is due to an uneasy feeling on the part of its opponents that time is on the other side, and that they can at best only put the clock back, not stop it.

Abstract
Purpose
The purpose of this paper is to explore the origin of economics as a separate science.
Design/methodology/approach
A very comprehensive approach is presented for determining the origin of economics as a science. Three kinds of inter‐related issues are discussed: how to interpret and evaluate earlier, particularly ancient, writings, the specification of the requirements for declaring economics as a science and the definition, scope and methodology of economics.
Findings
Application of the most stringent requirements for declaring economics as a separate science to Kautilya's Arthashastra validated A.K. Sen's claim that it is the first book on economics.
Research limitations/implications
According to Kautilya, economics is a separate science but not independent of other disciplines and particularly of ethics. Whereas, most of the current research ignores this inter‐dependence and consequently does not fully capture reality.
Practical implications
It implies that the inter‐dependence between economics and other disciplines should be encouraged and vigorously explored.
Originality/value
It validates Redman's assertion, “The history of economics as a science is, in my view, still waiting to be properly written”.
