The behaviour of light in white prints is dominated by the presence of titanium dioxide pigment, which is responsible for opacity. The pigment also strongly influences gloss and is responsible for the whiteness of prints.

The areal (surface area density of bits) storage density of magnetic hard disks is continually increasing, with typical available commercial storage densities being around 10Gbits/in². It is predicted that densities in excess of 40Gbits/in² will be possible before the year 2003. A number of key issues arise from this development, such as the need to determine and control accurately the dynamic flying height (z‐axis) of the read‐write head, which is affected by the apparent distortion of the disk surface due to rotation‐induced disk resonance. As a result of the increasing storage density the positional control of the head in the plane of the disk (x‐y plane) also becomes more critical. This paper deals generally, but with a particular emphasis on optical and piezoelectric sensors used in our laboratory for characterisation of storage media and systems.

This paper aims to focus on hybrid projects as a type of building adaptation work. It seeks to discuss the hybrid building design process in subsets of information and resulting decisions by highlighting the relationship between them. It also aims to present a conceptual framework which was developed by refining, or customising the RIBA Plan of Work.

Field theory formed the theoretical basis for the approach to mapping the hybrid project process. The conceptual framework itself evolved from a comprehensive literature review, case studies and a practice survey. In total, 11 design and construction professionals evaluated the framework and their comments and feedback are also discussed.

The discussion presents an approach which can be used to manage the delivery of hybrid projects, although it was found that the proposed framework can be applied to a wider spectrum of construction projects.

The evaluation of the framework was limited by the number of participants involved and the limited client representation.

The paper makes an original contribution by further exploring an increasingly relevant area of construction activity; building adaptations. Although the research focused specifically on the design‐specific stages of hybrid project delivery, findings contribute towards process improvement by emphasising the need for early information acquisition, early and precise definition of design intent, and collaborative design decision making. These three factors contribute highly to client/user satisfaction (value) and effective project delivery.

The aim of this study is to systematise the entrepreneurial coaching (EC) literature by understanding how the phenomenon has been investigated along four dimensions inspired by Gartner’s (1985) conceptualisation of entrepreneurship: entrepreneurial process, context, target and outcomes. In so doing, this study will provide a frame of its multifunctional role and identify relevant gaps and suggestions for future research.

We conducted a systematic literature review to collect existing works on EC. We analysed 85 selected papers with a qualitative content analysis that allowed us to highlight relevant research themes for the entrepreneurial process, context, outcomes and target.

Our results demonstrate that EC has a multifunctional role in entrepreneurship that can be summarised in five different typologies, depending on the stage of the entrepreneurial process in which it is applied, the context, the target and the outcomes.

As one of the first attempts to systematise studies on EC, this work extends previous conceptualisation of EC by detailing different typologies of this intervention, thereby contributing to reduced fragmentation and conceptual ambiguity.

This paper aims to develop a framework for optimising building performance through the integration between risk management (RM) and building information modelling (BIM) during the design process.

To achieve this aim, a research strategy consisting of literature review, case studies and survey questionnaire is designed to accomplish four objectives. First, to examine the concepts of design process, building performance, RM and BIM; second, to present three case studies to explain the role of using RM and BIM capabilities towards optimising building performance; third, to investigate the perception and application of architectural design firms in Egypt towards the role of RM and BIM for enhancing building performance during the design process; and finally, to develop a framework integrating RM and BIM during the design process as an approach for optimising building performance.

Through literature review, the research identified 18 risks that hamper optimising building performance during the design process. In addition, 11 building performance values and 20 BIM technologies were defined. Results of data analysis showed that “Design budget overrun”, “Lack of considering life cycle cost” and “Inefficient use of the design time” were ranked the highest risks that affect the optimisation of building performance. Respondents ranked “Risk avoid” or “Risk transfer” as the most risk responses adopted in the Egyptian context. In addition, “BIM As Built” was ranked the highest BIM technology used for overcoming risks during the design process. These findings necessitated taking action towards developing a framework to optimising building performance.

The research identified the risks that affect optimising building performance during the design process. It focuses on improving the design process through using the capabilities of BIM technologies towards overcoming these risks during the design process. The proposed framework which integrates RM and BIM represents a synthesis that is novel and creative in thought and adds value to the knowledge in a manner that has not previously occurred.

Different process models have been developed by academia and industry to enhance the effectiveness and efficiency of the design and construction activity in response to the need for improving performance. However, the effective and widespread adoption and use of process models have been limited, and the benefits resulting from these endeavours have been ambiguous at best and non‐existent at worst. This paper synthesises the key general and construction‐specific literature related to process model implementation around a generic model, providing a systematic picture on the current knowledge on implementation.

Secondary data sources were reviewed, criticised and synthesised. The books and academic papers identified focused on the areas of process management in construction and manufacturing, change management and knowledge/technology transfer.

The paper concludes that the body of literature related to process model implementation lacks an integrated focus and cohesion, and the need to appropriately locate and operate the implementation strategy within a visible organisational context is not adequately addressed.

The paper review and synthesis are limited to relevant literature within the context of implementation of process models.

Gaps in the literature are identified and discussed, and a set of questions proposed to stipulate future research.

The paper originality relates to providing a broad, systemic perspective on the complexity of process models implementation, analysing it from different but interrelated conceptual lenses.

The purpose of this paper is to develop a framework integrating risk management (RM) into the architectural design process (ADP) as an approach for delivering sustainable construction projects.

A research methodology, which consisted of literature review and field study, is designed to accomplish four objectives. First, to provide a comprehensive literature review of the concepts of sustainability, ADP and RM. Second, to present and synthesis the results of two relevant studies focused on identifying, quantifying and classifying the risks associated with ADP; and investigating the perception and application of Egyptian architectural design firms (ADFs) towards integrating RM into ADP as an approach for delivering sustainable construction projects. Third, to develop a framework that integrates RM into ADP towards delivering sustainable construction projects. Finally, to draw conclusions and recommendations to improve the practice of delivering sustainable construction projects among ADFs, construction professionals and governmental authorities.

ADP is a fundamental phase of the construction process because the decisions adopted during this phase affect the project performance throughout its life cycle. While RM is widely applied in different sectors of the construction industry, its application in ADP received scant attention in construction literature. The research identified 18 key risks that affect the sustainable delivery of construction projects during ADP. The architect, the client and the project manager are the highest ranked responsible parties for the occurrence of these key risks. The field study highlighted the need to develop a framework to facilitate integrating RM into ADP.

This paper focused only on the integration of RM into ADP.

The conducted literature review and field study provided an in-depth understanding of the key risks that affect the sustainable delivery of construction projects during ADP. Through its five stages, the proposed framework is expected to serve as a foundation for integrating RM into ADP as an approach for delivering sustainable projects. This ideology has received scant attention in construction literature. The developed framework represents a synthesis that is novel and creative in thought and adds value to the knowledge in a manner that has not previously occurred.

The purpose of this paper is to docoment a randomized controlled trial, with follow‐up at three and six months, to determine the impact of a coronary risk factor modification program for employees.

Intervention participants received a 12‐week health promotion program involving exercise, education seminars, nutritional analysis and smoking cessation counselling. Outcome measures included differences in coronary risk factors of control and intervention participants between baseline and three and six‐month follow‐up visits.

The participants included 566 individuals employed in the Halifax area, Nova Scotia, Canada. They were between 19 and 66 years old with at least two modifiable coronary risk factors. There were statistically significant differences at three months in coronary risk score improvement, smoking cessation, physical activity level increases, body mass index reductions and serum cholesterol. At six months, improvements remained significant except for cholesterol. Reduction in blood pressure was not significantly different. Intervention participants compared to control participants showed significant differences in both cardiac and stroke risk at three and six‐month visits.

This study demonstrates that employees had a significant coronary disease risk reduction as a result of a relatively short health promotion intervention. Benefits three months post‐intervention were not sustained to the same extent as during the intervention. This underscores the need for long‐term commitment with lifestyle changes and raises the issue of the need for a comprehensive approach that also addresses environmental factors.

This paper contributes to the current research base on this topic as there are few well‐designed studies to reduce coronary risk factors for employees.

This chapter considers the role of entrepreneurship theory in the development of ideation techniques for entrepreneurship education. It begins by considering how metatheories impact theory construction in entrepreneurship research and discusses the role of ontology, epistemology, axiology, as well as the role of assumptions about human nature and social change. The chapter presents four different paradigms of thought that apply different philosophies and illustrates how these different paradigms conceptualize entrepreneurship and entrepreneurial opportunity differently. The four paradigms include the equilibrium paradigm, the disequilibrium paradigm, the disruptive innovation paradigm, and the social constructionism paradigm. Within each paradigm, the nature of entrepreneurial opportunity is discussed, and the chapter provides examples to show how different ideation techniques can be generated from these different conceptualizations. Forms of ideation technique are presented and explained, as they relate to each paradigm, and the chapter concludes by explaining the value of these techniques for ideation, opportunity discovery, and creation, in the entrepreneurial process.

This study aims to evaluate factors influencing undergraduate students’ acceptance of a computer-aided learning resource using the Phantom Omni haptic stylus to enable rotation, touch and kinaesthetic feedback and display of names of three-dimensional (3D) human anatomical structures on a visual display.

The software was developed using the software development life cycle, and was tested by students enrolled in various bachelor degrees at three stages of development within the technology acceptance model, action research and design research methodology frameworks, using mixed methods of quantitative and qualitative analysis.

The learning system was generally well-accepted, with usefulness (72 ± 18, mean ± standard deviation, 0-100 visual analogue scale) rated higher (p < 0.001) than ease of use (57 ± 22). Ease of use ratings declined across the three versions as modules were added and complexity increased. Students with prior experience with 3D interfaces had higher intention to use the system, and scored higher on identification of anatomical structures. Students with greater kinaesthetic learning preferences tended to rate the system higher. Haptic feedback was considered the best aspect of the system, but students wanted higher spatial resolution and lower response times.

Previous research relating to haptic devices in medical and health sciences has largely focused on advanced trainees learning surgical or procedural skills. The present research suggests that incorporating haptic feedback into virtual anatomical models may provide useful multisensory information in learning anatomy at the undergraduate level.
