Abstract

Purpose

This paper aims to evaluate the sulfide stress cracking (SSC) resistance of L80 casing steels with different alloying chemistries (e.g. Ti-B and Mn-Cr-Mo) by correlating the reduction in area ratio with the mechanical property, inclusion and carbide.

Design/methodology/approach

SSC tests were conducted in 5.0 Wt.% sodium chloride and 0.5 Wt.% acetic acid solution saturated with H2S using constant load tensile method. The microstructure and fracture morphology of the steel were observed using scanning electron microscope. The inclusion and carbide were identified by energy dispersive spectroscopy and auger electron microscope.

Findings

Among all the testing steels, electric resistance welding (ERW) L80-0.5Mo steel demonstrates the highest SSC resistance because of its appropriate mechanical properties, uniform microstructure and low inclusion content. The SSC resistance of L80 steels generally decreases with the rising yield strength. The fracture mode of steel with low SSC resistance is jointly dominated by transgranular and intergranular cracking, whereas that with high SSC resistance is mainly transgranular cracking. SSC is more sensitive to inclusions than carbides because the cracks are easier to be initiated from the elongated inclusions and oversized oxide inclusions, especially the inclusion clusters. Unlike the elongated carbide, globular carbide in the steel can reduce the negative effect on the SSC resistance. Especially, a uniform microstructure with fine globular carbides favors a significant improvement in SSC resistance through precluding the cracking propagation.

Originality/value

The paper provides the new insights into the improvement in SSC resistance of L80 casing steel for its application in H2S environment through optimizing its alloying compositions and microstructure.

Abstract

Purpose

The purpose of this paper is to illustrate the systematic role played by Six Sigma methodology in improving the quality of healthcare. The literature review identifies the relevant opportunities for successful introduction and development of Six Sigma approach in healthcare sector.

Design/methodology/approach

A systematic methodology to identifying literature on Six Sigma in healthcare is presented. Web of Science, Medline, Emerald Insight, ASQ and ProQuest databases (1998-2016) were searched, and 68 papers of fair methodological quality were identified.

Findings

The findings of the systematic review reveal a growing interest in research on Six Sigma adoption in healthcare. The findings indicate that Six Sigma applications in healthcare have been focused on the entire hospital with no real focus on a particular department or function. The key findings on benefits, success factors, challenges and common tools of Six Sigma from the existing literature are also presented in the paper.

Research limitations/implications

The papers included in the systematic review were peer-reviewed papers available in English. Due to these limitations, relevant papers may have been excluded. Moreover, the authors have excluded all conference and white papers for their inclusion in this study.

Originality/value

This paper can serve as a guide on how Six Sigma approach can be applied to improve the quality of healthcare. The authors also believe that this is possibly the most comprehensive systematic literature review on the topic and will set the foundation for various research avenues based on the key findings of this study.

Abstract

Purpose

The paper aims to investigate disclosure practices in the annual reports of Libyan banks in the run‐up to the opening of the nation's first stock exchange. Banks dominate this embryonic market but very little research has examined the extent (or determinants) of transparency achieved by these firms, an issue argued by Stiglitz and others to be crucial in the post‐crisis era. Currently, no detailed evidence of disclosure practices prior to the launch of the exchange exists, making an accurate assessment of the market's impact in this area impossible; the present study therefore contributes in this regard as well.

Design/methodology/approach

The study employs two main methods: a disclosure index‐based analysis of mandatory and overall disclosure levels; and panel regression analysis of the determinants of the overall disclosure levels.

Findings

The results suggest that while many items are disclosed on a regular basis, on average barely more than half of all possible items appear in the annual reports. As regards compliance with mandatory requirements, the figures are higher but, worryingly, begin to fall as the launch of the market neared. The results of panel‐data analysis suggest that the overall extent of disclosure is non‐random, instead reflecting the profits achieved by the banks concerned.

Originality/value

This paper is the first detailed analysis of disclosure practices in Libyan banks and the results suggest that market authorities should be looking for an improvement in the figures, in particular the reversal of a downward trend in compliance with mandatory requirements. The paper reports a link between profit level and disclosure propensity; this evidence might be of use to regulators charged with increasing disclosure levels in the future. More generally, the results provide a comparative basis on which to assess the effect of the market's launch on disclosure practices in Libya.

Abstract

Purpose

The purpose of this study is to outline a conceptual framework that can be used to organise and guide future research into how celebrity product endorsement creates equity for both the endorsed product‐brand and the endorsing celebrity.

Design/methodology/approach

The theoretical perspective adopted in this study is that celebrity product endorsement is a form of co‐branding.

Findings

The central thesis is that both endorser image and brand image serve as mediators in the equity‐creation process of celebrity product endorsement.

Originality/value

Research contributions and directions for future research are provided.

Abstract

MID‐OCTOBER sees the activities of the library world in full swing. Meetings, committee discussions, schools at work, students busy with December and May examinations in view, and a host of occupations for the library worker. This year—for in a sense the library year begins in October—will be a busy one. For the Library Association Council there will be the onerous business of preparing a report on State Control; for libraries there will be the effort to retain readers in a land of increasing employment and reduced leisure; and for the students, as we have remarked in earlier issues, preparations for the new syllabus of examinations which becomes operative in 1938. It is a good month, too, to consider some phases of library work with children, “which,” to quote the L.A. Resolutions of 1917, “ought to be the basis of all other library work.”

Abstract

At a recent inquest upon the body of a woman who was alleged to have died as the result of taking certain drugs for an improper purpose, one of the witnesses described himself as “an analyst and manufacturing chemist,” but when asked by the coroner what qualifications he had, he replied : “I have no qualifications whatever. What I know I learned from my father, who was a well‐known ‘F.C.S.’” Comment on the “F.C.S.” is needless.

Abstract

Purpose

Through a critical review of the impact of luxury international business, this study aims to contribute to an understanding of business activities that depend on an unequal distribution of income and wealth.

Design/methodology/approach

Drawing on a wide range of academic and practitioner literature, this study adopts a critical luxury studies approach to provide an assessment of the economic and social impact of luxury international business.

Findings

Luxury is an increasingly important sector of the economy, which contributes to the welfare of increasing numbers of people across the world. Alongside its dependence on an unequal distribution of income and wealth and the negative aspects to which this gives rise, luxury business generates significant benefits to the economy and society through promoting economic growth, innovation, cultural enrichment, improved quality of the built environment and environmentally sustainable business practices. Nevertheless, an appropriate level of regulation and taxation on the excesses of contemporary luxury consumption could improve the welfare of all. Hence, luxury international business warrants investigation by critical scholars who recognize the complexity of the benefits and dark sides arising from luxury.

Research limitations/implications

This study draws on an extensive review of academic and practitioner literature. However, primary research is required to investigate further the key issues identified.

Social implications

Through an exploration of the impact of the production and consumption of luxury, this study reveals how luxury businesses serving the super-rich can contribute to the welfare of society whilst also giving rise to negative outcomes.

Originality/value

By adopting a critical luxury studies approach, this study offers an original contribution to the field of international business and introduces avenues for future critical international business research.
