Abstract
Purpose
This paper aims to present a multi-axis additive robot manufacturing system (ARMS) and demonstrate its beneficial capabilities.
Design/methodology/approach
ARMS was constructed around two robot arms and a fused filament fabrication (FFF) extruder. Quantitative experiments are conducted to investigate the effect of printing at different orientations with respect to gravity, the effect of dynamically changing build orientation with respect to the build tray when printing overhanging features, the effect of printing curved parts using curved, conformal layers. These capabilities are combined to print an integrated demonstrator showing potential practical benefits of the system.
Findings
Orientation with respect to gravity has no effect on print quality; dynamically changing build orientation allows overhangs up to 90° to be cleanly printed without support structures; printing an arch with conformal layers significantly increases its strength compared to conventional printing.
Research limitations/implications
The challenge of automatic slicing algorithms has not been addressed for multi-axis printing. It is shown that ARMS could eventually enable printing of fully-functional prototypes with embedded components.
Originality/value
This work is the first to prove that the surface roughness of an FFF part is independent of print orientation with respect to gravity. The use of two arms creates a novel system with more degrees of freedom than existing multi-axis printers, enabling studies on printing orientation relationships and printing around inserts. It also adds to the emerging body of multi-axis literature by verifying that curved layers improve the strength of an arch which is steeply curved and printed with the nozzle remaining normal to the curvature.

Abstract
This research is a 6-year extension of Bernardi's (2005) initial ranking of the top ethics authors in accounting; it also represents a broadening of the scope of the original data into accounting's top-40 journals. While Bernardi only considered publications in business-ethics journals in his initial ranking, we developed a methodology to identify ethics articles in accounting's top-40 journals. The purpose of this research is to provide a more complete list of accounting's ethics authors for use by authors, administrators, and other stakeholders. In this study, 26 business-ethics and accounting's top-40 journals were analyzed for a 23-year period between 1986 through 2008. Our data indicate that 16.8 percent of the 4,680 colleagues with either a PhD or DBA who teach accounting at North American institutions had authored/coauthored one ethics article and only 6.3 percent had authored/coauthored more than one ethics article in the 66 journals we examined. Consequently, 83.2 percent of the PhDs and DBAs in accounting had not authored/coauthored even one ethics article.

Abstract
Purpose
This paper aims to explore the development of the accountability ideals and practices of Quaker industrialists during the period 1840–1914.
Design/methodology/approach
The research employs a case study approach and draws on the extensive archives of Quaker industrialists in the Richardson family networks, British Parliamentary Papers and the Religious Society of Friends together with relevant contemporary and current literature.
Findings
Friends shed their position as Enemies of the State and obtained status and accountabilities undifferentiated from those of non-Quakers. The reciprocal influences of an increasingly complex business environment and radical changes in religious beliefs and practices combined to shift accountabilities from the Quaker Meeting House to newly established legal accountability mechanisms. Static Quaker organisation structures and accountability processes were ineffective in a rapidly changing world. Decision-making was susceptible to the domination of the large Richardson family networks in the Newcastle Meeting House. This research found no evidence of Quaker corporate social accountability through action in the Richardson family networks and it questions the validity of this concept. The motivations underlying Quakers’ personal philanthropy and social activism were multiple and complex, extending far beyond accountabilities driven by religious belief.
Originality/value
This research has originality and value as a study of continuity and change in Quaker accountability regimes during a period that encompassed fundamental changes in Quakerism and its orthopraxy, and their business, social and political environments.

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.

Town Clerk's Office, Town Hall, Bethnal Green, E. 18th November, 1916. To the Chairman and Members of the Public Health Committee. Mr. Chairman and Gentlemen, At a recent meeting of the Public Health Committee, the Chief Sanitary Inspector reported upon legal proceedings which had been unsuccessful owing to the case of “Hunt v. Richardson” decided by a King's Bench Divisional Court of five Judges on the 2nd June, 1916, and I then reported upon the legal aspect of the case.

Abstract
The deadhead subculture – centered around the band Grateful Dead – has been active for 50+ years. Despite its longevity, academic work is sparse compared to other music subcultures. Given its durability and resilience, this subculture offers an opportunity to explore subcultural development and maintenance. I employ a contemporary, symbolic interactionist approach to trace the development of deadhead subculture and subcultural identity. Although identity is a basic concept in subculture research, it is not well defined: I suggest that the co-creation and maintenance of subcultural identity can be seen as a dialectic between collective identity and symbolic interactionist conceptions of individual role-identity.

Abstract
East Asia's emergence as the forthcoming center of global manufacturing is leading nations in the region to reconsider their current and future role in the world economy. For its part, the Republic of Korea is pursuing a strategy to transform the country into the business hub of Northeast Asia. A central aspect in this strategy is the development of a regional “Pentaport” in the city of lncheon, which will consist of five components: an airport, a seaport, a business port, a technoport, and a leisure port. Hopefully, the Port of lncheon will be able to specialize in moving both coastal cargoes and transshipment cargoes to and from China and Japan using Short Sea Shipping (SSS). The first section of this paper provides an analysis of recent trade patterns between the Asian countries of the Asian-Pacific Economic Cooperation (APEC) agreement and the United States, with an emphasis on the Republic of Korea. The second part of the paper discusses current intermodal coastal shipping practices in the United States along the Gulf of Mexico and offers suggestions to the developers of Korea s Pentaport initiative; based upon observations in the United States, to maximize the likelihood of their success.

Abstract
In 1899 the medical practitioners of Dublin were confronted with an outbreak of a peculiar and obscure illness, characterised by symptoms which were very unusual. For want of a better explanation, the disorder, which seemed to be epidemic, was explained by the simple expedient of finding a name for it. It was labelled as “beri‐beri,” a tropical disease with very much the same clinical and pathological features as those observed at Dublin. Papers were read before certain societies, and then as the cases gradually diminished in number, the subject lost interest and was dropped.
