Abstract
Purpose
Regardless of the materials used, additive manufacturing (AM) is one of the most popular emerging fabrication processes used for creating complex and intricate structural components. This study aims to investigate the effects of process parameters – namely, nozzle diameter, layer thickness and infill density on microstructure as well as the mechanical properties of 17–4 PH stainless steel specimens fabricated via material extrusion AM.
Design/methodology/approach
The experimental approach investigates the effects of printing parameters, including nozzle diameter, layer thickness and infill density, on surface roughness, physical and mechanical properties of the printed specimens. The tests were triplicated to ensure reproducibility of the experimental results.
Findings
The highest ultimate tensile strength, 795.26 MPa, was obtained on specimen that was fabricated with a 0.4 mm nozzle diameter, 0.14 mm layer thickness and 30% infill density. Furthermore, a 0.4 mm nozzle diameter also provided slightly better ductility. This came at the expense of surface finishing, as a 0.25 mm nozzle diameter exhibited better surface finishing over a 0.4 mm nozzle diameter. Infill density was shown to slightly influence the tensile properties, whereas layer thickness showed a significant effect on surface roughness. By contrast, hardness and ductility were independent of nozzle diameter, layer thickness and infill density.
Originality/value
This paper presents a comprehensive analysis relating to various input printing parameters on microstructural, physical and mechanical properties of additively manufactured 17–4 PH stainless steel to improve the printability and processability via AM.

Abstract
Purpose
Poets House, a poetry special collection in New York, hosts an annual exhibit of the preceding year's poetry publications in the USA. This paper aims to offer a selection of recommended titles that reflect the range of poetry titles including single‐author works, anthologies, and prose about poetry.
Design/methodology/approach
The paper researched and requested donations of 2010‐2011 poetry titles from US poetry publishers to assemble and display a comprehensive collection of poetry publications, from which a selection of 50 titles was made. The selections should appeal to a range of poetry readers, from novices and students to poets looking to access the latest work from their peers.
Findings
Over 2,500 poetry titles were published and/or available to readers in the USA between June 2010 and June 2011. These titles range from mainstream publishers to independent presses to artists' collectives publishing works from established poets as well as emerging and international poets.
Research limitations/implications
Without a budget for collection development, the exhibit and resulting titles represent those which publishers have opted to donate to the library. Every effort is made to be all‐inclusive, with the understanding that publishers may send only a selection of their list. The selected titles herein are based on the titles received for the exhibition.
Practical implications
For 19 years Poets House's annual Showcase has been the main collection‐development tool. Publishers donate copies of their titles, which are arranged by publisher for a month‐long exhibition. This approach enriches the poetry special collection, a unique poetry library built on community participation. The all‐inclusive collection‐development approach results in a full representation of poetry publishing.
Originality/value
A selection made from a comprehensive collection of the year's poetry titles offers a sample of poetry publishing from large to small presses and the self‐published in the USA.

Abstract
Purpose
The purpose of this paper is to design a special automatic redundant robot painting system (RRPS), which can automatically navigate and paint in the long non-regular duct.
Design/methodology/approach
The RRPS is designed with three subsystems: a redundant robot, a spraying system and a control and safety system. Based on the modular design theory, the robot falls naturally into a mobile platform, a 4-DOF location mechanism and a 10-DOF manipulator. The restriction of the distance between the links and the duct axis is used to plan the trajectory of the manipulator so that it would not collide with the duct. The restriction model is constructed by minimizing the sum of the weighed distances between the duct axis and the special points.
Findings
A fully working prototype system has been developed. Test results show that the minimal distance between the robot joints and duct is 18 mm, and it can finish painting long non-regular ducts at the speed of 12.5 cm/s and the spraying distance of 16 cm. The quality of coating layers is good.
Practical implications
The RRPS was used to paint non-regular rectangular ducts, cylindrical ducts and long non-regular ducts. The feasibility of painting long non-regular duct is proved with the prototype implementation and successful test results.
Originality/value
The RRPS shows a novel solution that is based on the 14-DOF redundant robot design for painting long non-regular ducts which is used in airplane.

Abstract
Purpose
The paper aims to explore the extent to which the legal experience of minority shareholder actions in Hong Kong supports the sociological model of the Chinese family firm as developed by Wong Siu‐lun and reports some preliminary findings for the period 1980‐1995.
Design/methodology/approach
This paper is based upon the analysis of 275 minority shareholder petitions in the High Court of Hong Kong between the years 1980 and 1995 inclusive. It also draws upon material from a questionnaire sent to law firms involved in those petitions and interviews with members of the Hong Kong judiciary with experience of hearing minority shareholder cases, members of the legal profession and accounting and company secretarial professions directly or indirectly involved in the administration of companies in Hong Kong and regulators.
Findings
The findings indicate that the problematic early, emergent stage of the model as described by Wong Siu‐lun is quite accurate. Whilst there is considerable support for some aspects of the model of the Chinese family firm, the experience indicates a number of complex dynamics at play, some of which the model does not take into account. However, the findings, at least by implication, do point to the cohesive strength of the Chinese family firm with occasional fault lines resulting in some “disputes” of earthquake proportions which may rumble on in some cases for years.
Practical implications
The findings demonstrate the usefulness of lifecycle modeling of the family and other type of corporate firm. It also demonstrates some of the complex subtleties at play. The findings also have implications for the law matters thesis of La Porta et al.
Originality/value
This is one of the first studies to actually examine the legal experience of minority shareholder protection in a particular jurisdiction (Hong Kong) by examining the petitions and writs actually filed and relating them to a sociological model of the Chinese Family firm.

Abstract
An appeal under the Food and Drugs Acts, reported in the present number of the BRITISH FOOD JOURNAL, is an apt illustration of the old saying, that a little knowledge is a dangerous thing. In commenting upon the case in question, the Pall Mall Gazette says: “The impression among the great unlearned that the watering of the morning's milk is a great joke is ineradicable; and there is also a common opinion among the Justice Shallows of the provincial bench that the grocer who tricks his customers into buying coffee which is 97 per cent. chicory is a clever practitioner, who ought to be allowed to make his way in the world untrammelled by legal obstructions. But the Queen's Bench have rapped the East Ham magistrates over the knuckles for convicting without fining a milkman who was prosecuted by the local authority, and the case has been sent back in order that these easygoing gentlemen may give logical effect to their convictions.”

Abstract
This paper presents an overview of past and present research projects associated with electronic document delivery. The paper briefly outlines the Follet Report and introduces the UK's Electronics Libraries Programme, including the recently funded Focused Investigation of Document Delivery (FIDDO) project at Loughborough University. Four research areas have been identified as follows: resource sharing projects; network communication projects; electronic scanning projects and electronic document delivery systems. Conclusions highlight the major impact that technological developments are currently having on this area, the need for librarians to reassess their role in the information chain, and the need for delivery systems capable of handling different formats and a wider coverage of material to satisfy requests.

Abstract
Purpose
If proficient boards result in better governance, as the literature on the subject generally suggests, engaging independent directors and having in place an effective audit committee would certainly facilitate productive corporate functioning and enhanced accountability. Motivated by such a viewpoint, the purpose of this paper is to unravel the reporting quality and performance of the Indian central public sector enterprises (CPSEs) and its private counterparts.
Design/methodology/approach
The well premeditated propositions of the study resulted in a final sample comprising 47 CPSEs and 30 peer companies. The auditors' report on financial statements was scanned to determine the quality of company's accounting and financial reporting systems. The BSE‐500 Index companies were ranked on select financial parameters to gauge relative performance of the sample companies.
Findings
An analysis of the CPSEs shows that non‐compliance with the corporate governance provisions with regards to the required number of independent directors on the board did not have any concomitant effect on their performance. Further, an examination of auditors' report revealed that the CPSEs provide a better insight into books of accounts, unlike the private sector.
Originality/value
The study is timely and relevant, given the expanded role of the state and renewed interest in boards. A case for collaborative engagement between the government and the corporate sector is proposed to address legal as well as regulatory lacunae for building trust and fostering good corporate governance. To ensure better compliance and enforcement of financial regulations it envisions an integrated accounting/auditing and taxation administration platform.

Abstract
Purpose
This study aims to examine whether the presence of advisory directors affects firm discretionary accruals (DACC), a widely used proxy for financial reporting quality. The authors argue that the advisory director weakens the board monitoring role and impairs the firm financial reporting quality by increasing DACC.
Design/methodology/approach
The sample consists of listed firms on the Australian Stock Exchange from 2001 to 2015 using 7,649 firm-year observations. The authors perform descriptive statistics, regression and propensity score matching analyses to examine the research hypothesis.
Findings
The research evidence that firms with a higher presence of advisory directors have more DACC, indicating poor financial reporting quality. Furthermore, the authors categorize the DACC and find that the firm has higher income-increasing DACC in the presence of higher advisory directors. The findings are robust concerning endogeneity issues.
Research limitations/implications
The research evidence that firms with a higher presence of advisory directors have more DACC, indicating poor financial reporting quality. Furthermore, the authors categorize the DACC and find that the firm has higher income-increasing DACC in the presence of higher advisory directors. The findings are robust concerning endogeneity issues.
Practical implications
The research contributes valuable insights for regulators and policymakers seeking to comprehend the implications of firms using more advisory directors. Additionally, the authors recognize the potential significance of the findings for the institution of directors, as they can provide a nuanced understanding of the specific roles played by advisory directors in organizational dynamics.
Originality/value
While the extensive body of literature on corporate governance and financial reporting quality has been well-established, a noticeable void exists in academic research delving into the relationship between advisory directors and DACC management. This study seeks to fill this gap, making a distinctive and original contribution to the existing literature on corporate governance.
