Abstract
Purpose
Aims to develop a greyscale “painting system” by enabling the physical reproduction of digital texture maps on arbitrary 3D objects selectively exposing “pixels” of photographic emulsion with a robot mounted light source.
Design/methodology/approach
After reviewing existing methods of “decorating” 3D components, the properties of photographic emulsion are introduced and the nature of the rendering process' pixels discussed. A proposed path planning algorithm, used to derive both the robot's movement and the exposure times directly from a VRML representation, is then presented.
Findings
Results obtained from successfully rendering images on the surface of a test object are presented.
Research limitations/implications
Limitations of current system include the overall process time and the inability to handle objects with concave geometry.
Originality/value
The system requires no bespoke production tooling and fills an automation gap in rapid prototyping and manufacturing technology that is currently occupied by hand painting.

Abstract
A robust and non‐intrusive focus control system for laser welding has been developed under a collaboration between GSI Lumonics (Rugby) and Heriot‐Watt University in Edinburgh, as part of the Laser Engineering for Manufacturing Applications Programme (LEMA), funded by EPSRC. It uses the light generated by the process, together with the chromatic aberrations of the focusing optics to determine the focal position of the laser relative to the workpiece. Successful closed loop operation has been demonstrated over a wide range of welding conditions, including different materials and laser powers.

Abstract
Purpose
Globally, mobile technology is a significant factor influencing how libraries are changing the ways of delivering services to today’s users. This paper aims to explore academic librarians’ perceptions of the usefulness of mobile technology in delivering library services and the efforts required for its successful adoption.
Design/methodology/approach
The study was conducted within an interpretive paradigm. The research objectives were underpinned by the unified theory of acceptance and use of technology as a theoretical framework. Data were collected through semi-structured interviews and analyses using NVIVO for thematic analysis.
Findings
Results show that, in general, academic librarians support the use of mobile technology to provide services such as access to eBooks and Journals, Online Public Access Catalogue, Bookmyne application, information literacy consultations and training. Library managers, fellow librarians and users were identified as encouraging the adoption of mobile technology to enhance library services. The paper further confirms that the successful adoption of mobile technology requires some effort. However, due to some of the challenges presented in the study, a majority of respondents felt that their libraries are not yet ready to fully embrace mobile technology the way it is envisioned in today’s world.
Practical implications
The study endeavours to address the divergence between students and academic librarians’ viewpoints regarding the application of mobile technology in the provision of library services.
Originality/value
This paper highlights numerous ways that academic librarians could adopt and embrace mobile technology, which can benefit both academic libraries and other institutions of higher learning. The knowledge presented in this paper could assist academic librarians in assessing their institutions’ vulnerabilities, challenges and strengths in using mobile technologies to provide library services.

Abstract
Means, medians and SD for available socio‐economic status (SES) black‐white differences are here substituted for those of IQ in a between‐groups model published by the author over a decade ago. The goodness of fit of the SES variables used is compared with that for the earlier IQ data. Even when SES variables are relatively successful this can be viewed as additional evidence of the importance of IQ differences to black‐white differences in delinquency.

Abstract
Since their creation through the Industrial Training Act 1964 to hear appeals against levies, the jurisdiction of industrial tribunals has grown considerably. One aspect of this jurisdiction, unfair dismissal, is examined here. Basic principles related to the law of unfair dismissal are examined. The practice and procedure of an industrial tribunal solely in connection with unfair dismissal cases are examined in greater detail. A case study is used to illustrate the important aspects of procedure. Appendices give relevant forms and extracts from the appropriate Code of Practice.

Abstract
The U.S. Census Bureau, health data providers, and credit bureaus are information organizations (IOs). They collect, store, and process large sets of sensitive data on individuals, households, and organizations. Storage, processing, and dissemination technologies that IOs employ have grown in capability, sophistication, and cost‐effectiveness. These technologies have outpaced the design and implementation of procedures for protecting data in transfer from primary data provider to IO and from IO to data user. On the one hand, it is necessary to protect the confidentiality of such data; on the other hand, it is necessary to protect the accessibility to the data by users, including researchers and analysts. Conflicts ensue in the two corresponding arenas: between the IO and data providers concerned with inadequate privacy and confidentiality protection; and between the IO and data users who find their access to data restricted. In this article third‐party mechanisms for managing disputes in the privacy and information area are both theoretically justified and their empirical manifestations examined The institutional mechanisms considered include privacy and information clearinghouses, a “Better Data Bureau,” a privacy information advocate, a data ombuds, a privacy mediator, an internal privacy review board, and a data and access protection commission. Under appropriate circumstances, these arrangements promise a more flexible and responsive resolution of the conflict between privacy/confidentiality and legitimate information access than is possible through legislative action and administrative rulings alone.

Abstract
A collection of essays by a social economist seeking to balance economics as a science of means with the values deemed necessary to man′s finding the good life and society enduring as a civilized instrumentality. Looks for authority to great men of the past and to today′s moral philosopher: man is an ethical animal. The 13 essays are: 1. Evolutionary Economics: The End of It All? which challenges the view that Darwinism destroyed belief in a universe of purpose and design; 2. Schmoller′s Political Economy: Its Psychic, Moral and Legal Foundations, which centres on the belief that time‐honoured ethical values prevail in an economy formed by ties of common sentiment, ideas, customs and laws; 3. Adam Smith by Gustav von Schmoller – Schmoller rejects Smith′s natural law and sees him as simply spreading the message of Calvinism; 4. Pierre‐Joseph Proudhon, Socialist – Karl Marx, Communist: A Comparison; 5. Marxism and the Instauration of Man, which raises the question for Marx: is the flowering of the new man in Communist society the ultimate end to the dialectical movement of history?; 6. Ethical Progress and Economic Growth in Western Civilization; 7. Ethical Principles in American Society: An Appraisal; 8. The Ugent Need for a Consensus on Moral Values, which focuses on the real dangers inherent in there being no consensus on moral values; 9. Human Resources and the Good Society – man is not to be treated as an economic resource; man′s moral and material wellbeing is the goal; 10. The Social Economist on the Modern Dilemma: Ethical Dwarfs and Nuclear Giants, which argues that it is imperative to distinguish good from evil and to act accordingly: existentialism, situation ethics and evolutionary ethics savour of nihilism; 11. Ethical Principles: The Economist′s Quandary, which is the difficulty of balancing the claims of disinterested science and of the urge to better the human condition; 12. The Role of Government in the Advancement of Cultural Values, which discusses censorship and the funding of art against the background of the US Helms Amendment; 13. Man at the Crossroads draws earlier themes together; the author makes the case for rejecting determinism and the “operant conditioning” of the Skinner school in favour of the moral progress of autonomous man through adherence to traditional ethical values.

Abstract
A distinction must be drawn between a dismissal on the one hand, and on the other a repudiation of a contract of employment as a result of a breach of a fundamental term of that contract. When such a repudiation has been accepted by the innocent party then a termination of employment takes place. Such termination does not constitute dismissal (see London v. James Laidlaw & Sons Ltd (1974) IRLR 136 and Gannon v. J. C. Firth (1976) IRLR 415 EAT).
