Abstract
X‐ray laminographic image can provide more useful information about the internal state of electronic packaging than x‐ray radiographic image does. Many kinds of laminographic system have been developed for obtaining the cross‐sectional image. Proposes an axial laminographic system, which can be constructed by usual automatic radiographic system without any rotating x‐ray head and detector system. Explains that this method can be implemented to make the usual radiographic x‐ray inspection system equal to the power of a laminographic system.

Abstract
Purpose
As additive manufacturing techniques, such as selective laser melting, allow for straightforward production of parts on basis of simple computer-aided design files only, unauthorized replication can be facilitated. Thus, identification and tracking of individual parts are increasingly vital in light of globalized competition. This paper aims to overcome the susceptibility of additive manufacturing techniques for product piracy by establishing a method for introducing and reading out product identification markers not visible by naked-eye inspection.
Design/methodology/approach
Lasers of different nominal power were used for altering the solidification mechanisms during processing in distinct areas of the samples. The resulting local microstructural characteristics and mechanical properties, respectively, were determined by scanning electron microscopy and hardness measurements. The applicability of an advanced eddy current technique for reading out local differences in electro-magnetic properties was examined.
Findings
The findings show that distinct microstructural features are obtained in dependence of the locally applied laser power. These features manifest themselves not only in terms of grain morphology, texture and hardness but also induce changes in the local electro-magnetic properties. The inscribed pattern can be non-destructively visualized by using an advanced eddy current technique.
Originality/value
Conventional copy protection basically consists in supplementary labelling or surface modification. In the present study, a new method is proposed for additively manufactured parts, overcoming the drawbacks of the former methods through process-induced microstructure manipulation. Slight alterations in the electro-magnetic material properties can be detected by advanced eddy current method allowing for identification of arbitrary and inimitable component information in additively manufactured parts.

Abstract
The fall of the Soviet Union and the end of socialism has come as a surprise but has been hailed nearly all over the world. The failure of the socialist model seems to have shown the superiority of the capitalist approach. The first sentence of Erich Fromms famous work “The Sane Society”, written at the end of the Second World War, is not strong enough to stimulate a discussion any longer. It is not less true nowadays than it was some forty years ago: “Nothing is more common than the idea that we, the people living in the Western world of the twentieth century, are eminently sane”.

Abstract
This paper compares quality management practices in manufacturing companies in the East and the West. It uses data collected from three countries in the East, namely Japan, Korea and Taiwan and compares these with data collected from four countries in the West, namely Denmark, Finland, Sweden and Australia. Twenty‐five Japanese companies, 105 Korean companies, 48 Taiwanese companies, 65 Danish companies, 88 Swedish companies, 18 Finnish companies and 62 companies from Australia responded to the questionnaire. Comparison between the East and the West is carried out on the following: formulation and communication of a quality policy; education and training of employees in quality management; top management participation in quality activities, quality motivation and suggestions; and the use of quality tools and methods. The comparison shows that quality management practices are relatively more widespread in the Eastern companies than in the Western companies. The key differences between the East and the West are identified and suggestions made to close the gap.

Abstract
While liberals agree that the best society is one that supports the equal exercise of personal liberty, there is little agreement among them on what policies best achieve this end. Conflicts within liberalism over the place of socially derived goals vis-à-vis personal liberty and autonomy create tension and skew public discourse on policy alternatives. In this article, I characterize the debate among dominant strands of liberal ideology and consider the effort of Charles Taylor to resolve these tensions. Finding his resolution unsatisfying, I explore the alternative conception offered by American pragmatism. I argue that liberal theories fail because they fall prey to the problem of principles-they attempt to justify axiomatic thinking rather than perpetuate society and culture. Pragmatism provides a justification for liberal public discourse as the best mechanism for constructing, evaluating and revising policies that support cultural adaptation to social, economic and technological contingencies.

Abstract
Purpose
Studies that investigate the length of stay as a predictor of consumer post-purchase behavior are rare despite its importance in efficient hotel management. By analyzing online customer reviews, this study aims to fill this gap in the extant literature on the relationship between length of stay and customer satisfaction level.
Design/methodology/approach
The authors collected and used online review data on hotels in London for this study. A series of linear regression analyses were conducted to examine the effect of length of stay on customer satisfaction as measured by review ratings. The authors used the Mahalanobis matching approach to confirm the empirical findings.
Findings
This analysis shows that length of stay is negatively associated with customer satisfaction. Additionally, the authors find that this negative relationship is stronger in high-end hotels than in low-end hotels.
Research limitations/implications
The research findings contribute to the literature by shedding light on a new stream of research, namely, length of stay. Additionally, the research findings offer novel insights that could help hotel managers understand the trade-off between longer stays and customer satisfaction.
Originality/value
To the best of the authors’ knowledge, this is one of the first few studies to show the systematic impact of length of stay on the valence of online review ratings, as well as the moderating effect of hotel levels by analyzing customer online reviews on hotel experiences.

Abstract
Purpose
This paper aims to present findings from a research project that investigated the suitability of Lean in a seasonal horticultural setting, specifically the New Zealand (NZ) apple and pear (pipfruit) industry. The paper focusses on improvements made while deploying Lean elements in several apple pack-houses.
Design/methodology/approach
The literature review discusses how common theoretical Lean themes are not industry or contextually bound and may be transferable to other industries. An industry-wide survey assesses the current state of knowledge and Lean deployment within the industry using a unique “single-question-per-day” approach. Two case studies and one action research study are used to obtain rich data from organisations that have implemented Lean in recent times. Reliability and validity is achieved by selecting representative samples, using a case study protocol, a single researcher for consistency, participant verification, multiple sources of evidence within cases and replication logic.
Findings
The industry survey shows a low level of knowledge and applied Lean within the industry. Data demonstrate that significant progress is made, using different implementation approaches that lead to a measurable increase of Lean, supported by some positive financial indicators.
Research limitations/implications
This research is restricted to NZ apple pack-houses, but indicates that Lean can contribute significantly to general horticultural pack house performance.
Originality/value
Literature research shows that little research has been done to study Lean in the horticultural field generally and in the NZ pipfruit industry specifically. This paper contributes to filling that knowledge gap.

Abstract
This paper views the economic situation for electronic component manufacturers worldwide, focusing particularly on those in Europe. It notes that recovery will proceed at a greatly varying pace, not only from one country to another but also based on sector or company‐specific factors. It also states that, in future, consumer goods of all kinds – primarily mass‐market electronic products – will be produced almost without exception in China and south‐east Asia.

Abstract
The Taylorisation of the Production area over the last decades has brought mass manufacturing coupled with a dramatic decrease of unit costs, thus making most goods cheaper and, therefore, generally affordable. At the same time, however, a most costly and valuable resource, namely the employee's personal capacity, most notably his problem‐solving ability, has become greatly underutilized.

Abstract
This paper synthesizes existing experimental research in the area of investor perceptions and offers directions for future research. Investor-related experimental research has grown substantially, especially in the last decade, as it has made valuable contributions in establishing causal links, examining underlying process measures, and examining areas with little available data. Within this review, I examine 121 papers and identify three broad categories that affect investor perceptions: information format, investor features, and disclosure credibility. Information format describes how investors are influenced by information salience, information labeling, reporting and accounting complexity, financial statement recognition, explanatory disclosures, and proposed disclosure changes. Investor features describes investors’ use of heuristics, investor preferences, and the effect of investor experience. Disclosure credibility is influenced by external and internal assurance, management credibility, disclosure characteristics, and management incentives. Using this framework, I summarize the existing research and identify areas that would benefit from additional research.
