Abstract
Purpose
This study aims to examine ship loading strategies during large-scale military deployments. Ships are usually loaded to a stowage goal of about 65% of the ship's capacity. The authors identify how much cargo to load onto ships for each sailing and propose lower stowage goals that could improve the delivery of forces during the deployment.
Design/methodology/approach
The authors construct several mixed integer programs to identify optimal ship loading strategies that minimize delivery timelines for notional, but realistic, problem variables. The authors study the relative importance of these variables using experimental designs, regressions, correlations and chi-square tests of the empirical results.
Findings
The research specifies the conditions during which ships should be light loaded, i.e. loaded to less than 65% of total capacity. Empirical results show cargo delivered up to 16% faster with a light-loaded strategy compared to fully loaded ships.
Research limitations/implications
This work assumes deterministic sailing times and ship loading times. Also, all timing aspects of the problem are estimated to the nearest natural number of days.
Practical implications
This research provides important new insights about optimal ship loading strategies, which were not previously quantified. More importantly, logistics planners could use these insights to reduce sealift delivery timelines during military deployments.
Originality/value
Most ship routing and scheduling problems minimize costs as the primary goal. This research identifies the situations in which ships transporting military forces should be light loaded, thereby trading efficiency for effectiveness, to enable faster overall delivery of unit equipment to theater seaports.

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
WHILE there is no doubt that the system of issuing books at “net” prices is of great benefit to booksellers, there is also no doubt that, unless care is taken, it is a serious drain upon a limited book‐purchasing income. A few years ago the position had become so serious that conferences were held with a view to securing the exemption of Public Libraries from the “net” price. The attempt, as was perhaps to be expected, failed. Since that time, the system has been growing until, at the present time, practically every non‐fictional book worth buying is issued at a “net price.”

Abstract
The following classified, annotated list of titles is intended to provide reference librarians with a current checklist of new reference books, and is designed to supplement the RSR review column, “Recent Reference Books,” by Frances Neel Cheney. “Reference Books in Print” includes all additional books received prior to the inclusion deadline established for this issue. Appearance in this column does not preclude a later review in RSR. Publishers are urged to send a copy of all new reference books directly to RSR as soon as published, for immediate listing in “Reference Books in Print.” Reference books with imprints older than two years will not be included (with the exception of current reprints or older books newly acquired for distribution by another publisher). The column shall also occasionally include library science or other library related publications of other than a reference character.

Abstract
Although fewer than 150 years have passed since Jacques Daguerre perfected the first photographic image in 1839, the flood of evolving equipment and applications has already generated a broad and richly varied field. Simultaneously one of the youngest arts and one of the newest technologies, photography is now used in medical research, space exploration, criminal investigations, agricultural production, design of industrial machinery, ad infinitum. At one extreme, it records family life and supplies the surest method of identification on drivers' licenses. At the other end of the spectrum, photography (once denounced in haute couture) has within the past five years not only become an “acceptable” art form, but has assumed centerstage in museums and exhibits throughout the United States and Europe.

Abstract
Purpose
The purpose of this paper is to reveal the assumptive concept of internationalization because it is discussed and understood in the international business (IB) literature. This paper develops a framework to reconceptualize internationalization in the context of global value chain (GVC) and sustainability. Based on this conceptual framework, this paper aims to formulate interrelated propositions to define internationalization.
Design/methodology/approach
This paper reviews the assumptive conceptualization process based on empirical evidence obtained through qualitative, illustrative and descriptive content analysis methods. Through the collection and qualitative content analysis of milestone papers, this paper demonstrates the fragmentation of the concept of internationalization. This paper reviews the evolving nature of the concept of internationalization, analyzing the accumulative issues associated with defining internationalization, as well as its potential future development.
Findings
This paper introduces a dynamic perspective on the evolving nature of the concept of internationalization and argue there is a need to reconceptualize internationalization in the context of the GVC and sustainability.
Originality/value
After reviewing the context in which the term “internationalization” has been applied and taking into consideration the current trends in the IB, this paper formulates an updated definition of the term internationalization. This paper offers a viewpoint on the future direction of the concept of internationalization in light of the growing importance of sustainability within IB.
