Abstract
The mid-1990s marked a paradigm shift in the way physical activity is promoted, and walking is now considered the most suitable type of physical activity for widespread promotion. Accurate measurement underpins public health practice, hence the aims of this chapter are to: (1) provide a typology for the measurement of walking; (2) review methods to assess walking; (3) present challenges in defining walking measures; (4) identify issues in selecting instruments for the evaluation of walking and (5) discuss current efforts to overcome measurement challenges and methodological limitations. The taxonomy of walking indicates that secondary purpose walking is a more complex set of behaviours than primary purpose walks. It has many purposes and no specific domain or intensity, may lack regularity, and therefore poses greater measurement challenges. Objective measurement methods, such as accelerometers, pedometers, smartphones and other electronic devices, have shown good approximation for walking energy expenditure, but are indirect methods of walking assessment. Global Positioning System technology, the ‘Smartmat’ and radio-frequency identification tags are potential objective methods that can distinguish walkers, but also require complex analysis, are costly, and still need their measurement properties corroborated. Subjective direct methods, such as questionnaires, diaries and direct observation, provide the richest information on walking, especially short-term diaries, such as trip records and time use records, and are particularly useful for assessing secondary purpose walking. A unifying measure for health research, surveillance and health promotion would strongly advance the understanding of the impact of walking on health.

Abstract
This chapter discusses how attachment theory, a theory that provides insight into the processes through which psychological and emotional bonds are developed in relationships, can be useful for understanding mentoring relationships. We develop a conceptual model emphasizing how attachment-related constructs and their relationships with mentors’ and protégés’ behaviors and emotions influence each phase of a mentoring relationship. Recognizing reciprocity in the mentoring process, the model also explains how the interpersonal dynamics of the mentor–protégé relationship influence the benefits gained by both partners. Propositions for future research on mentoring relationships are provided. We contend that examining mentoring through the lens of attachment theory can increase our understanding of the underlying factors or mechanisms that determine individuals’ involvement in mentoring relationships and differentiate successful from unsuccessful mentoring relationships. The research and practical implications are discussed.

Abstract
The spectral boundary element method for solving two‐dimensional transient heat conduction problems is developed. This method is combined with the fast Fourier transform (FFT) to convert the solution between the time and frequency domains. The fundamental solutions in the frequency domain, required for the present method, are discussed. The resulting line integrations in the frequency domain are discretized using constant boundary elements and used in a Fortran boundary element program. Three examples are used to illustrate the accuracy and effectiveness of the method in both the frequency and time domains. First, the frequency domain solution procedure is verified using the steady‐state example of a semi‐infinite half space with a heat flux applied to a patch of the surface. This spectral boundary element method is then applied to the problem of a circular hole in an infinite solid subjected to a time‐varying heat flux, and solutions in both the frequency and time domains are presented. Finally, the method is used to solve the circular hole problem with a convection boundary condition. The accurary of these results leads to the conclusion that the spectral boundary element method in conjunction with the FFT is a viable option for transient problems. In addition, this spectral approach naturally produces frequence domain information which is itself of interest.

Abstract
Total Quality Management (TQM), this framework proposes, can be achieved only when the organization develops the ability to cater to customers' needs, monitor the internal and external environments on an ongoing basis to obtain and disseminate information needed by empowered group decision makers, establish and maintain an atmosphere where there is strong vertical and horizontal communication, collaboration, and cooperation among individuals in internal units, as well as among individuals in external units, develop and maintain a bond and a “sense of ownership” among employees; and develop and maintain ongoing training programs.
