The finite element analysis capabilities of DART and the design routines for the computerized design in accordance with CP 110 and BS 5337 are briefly described. The DART program is used to compare some reservoir roof systems including a novel floated dome. Temperature effects on reservoirs can appear to yield severe stresses, but do they? The DART program is used for the design of non‐axisymmetric loaded structures and examples are given of wind loads on water towers and chimneys. A simple procedure has been incorporated into DART to allow for soil—structure interaction. The DART program can print out reinforcing or prestressing requirements. An elementary cost study has been made on reservoir walls to compare the relevant merits of the two methods of design. A facility has been incorporated into the DART program to find the optimum shape of reservoirs and water towers for a given set of construction costs. The Dynamic Programming method has been used for this purpose. Natural frequencies and mode shapes can be determined by the DART program using the Sturm sequence property and inverse iteration respectively.

As a Data Envelopment Analysis (DEA) extension tool, cross-evaluation method was developed to evaluate Decision Making Units’ (DMUs) performances in a competitive situation with limited demand. It identifies DMUs with best performances and rank them by applying peer evaluation mode instead of self-evaluation mode. However, it has limitations in efficiency improvement. That is, it fails to give direct information on how to improve efficiencies of the inefficient DMUs. In this chapter, we propose an alternative way to apply cross-evaluation in efficiency improvement. First, an appropriate and feasible suggestion is proposed to minimize the variation between the weights of a DMU's own optimal Charnes-Cooper-Rhodes (CCR) efficiency and the weights guaranteeing its cross-efficiency score. We exploit several transformations to convert nonlinear programming into a linear one. As a result, an overall optimal set of the weights is obtained, which precisely illustrate the preferences of decision makers and exact characteristics of production process of the evaluated DMU. A further discussion is advanced to examine the existence of non-uniqueness of the weights and to differentiate various sets of the optimal weights by suggesting a unique feasible set of multipliers to best represent the alternative weights selection criterion. Moreover, we develop several models to reallocate the inputs and outputs of inefficient DMUs with minimum amelioration as well as consideration of the preference of decision makers. Finally, we apply our models to evaluate competitive advantages of Chinese cities.

The purpose of this paper is to present an objective decision-making framework and conduct a benchmarking study in the air cargo industry.

The decision-making framework and benchmarking methodology evaluates the aircraft value for money (VfM) as a benefit-to-cost ratio calculated adopting a measure of relative efficiency. This efficiency score is measured as a comprehensive efficiency index obtained by combining several efficiency scores calculated by implementing four data envelopment analysis (DEA) models.

The framework is used to carry on a benchmarking study in the air cargo industry on a sample of 27 airplanes. The average VfM is 67.04 percent, with measurements between 39.96 and 116.03 percent. Only three airplanes achieve full VfM and behave as benchmarks to the remaining airplanes. Boeing B727-200 is a broad player in the market. Some old cargo models (DC 9-30F) deliver the same amount of VfM as more recent aircraft models (i.e. MD-11F and A300-600F).

The decision-making framework and benchmarking methodology can usefully support managers to make sound decisions and plans. Even though DEA generates attributes weights to different alternatives that are independent of the buyer preferences, the framework flexibility allows introducing a weighting scheme to take into account the managers preferences for certain aircraft performance/functional features. It can easily include new functional/performance measurements and adapt the VfM measurement to the particular economic context, strategy, and business model of the airlines, or be transferred to different industries.

The framework combines technical, functional performance, and economic cost measurements to get a unique efficiency index to evaluate the airplane VfM.

Accounting’s definition of accountability should include attributes of socioenvironmental degradation manufactured by unsustainable technologies. Beck argues that emergent accounts should reflect the following primary characteristics of technological degradation: complexity, uncertainty, and diffused responsibility. Financial stewardship accounts and probabilistic assessments of risk, which are traditionally employed to allay the public’s fear of uncontrollable technological hazards, cannot reflect these characteristics because they are constructed to perpetuate the status quo by fabricating certainty and security. The process through which safety thresholds are constructed and contested represents the ultimate form of socialized accountability because these thresholds shape how much risk people consent to be exposed to. Beck’s socialized total accountability is suggested as a way forward: It has two dimensions, extended spatiotemporal responsibility and the psychology of decision-making. These dimensions are teased out from the following constructs of Beck’s Risk Society thesis: manufactured risks and hazards, organized irresponsibility, politics of risk, radical individualization and social learning. These dimensions are then used to critically evaluate the capacity of full cost accounting (FCA), and two emergent socialized risk accounts, to integrate the multiple attributes of sustainability. This critique should inform the journey of constructing more representative accounts of technological degradation.

The reduction in IC package lead pitches in surface mount solder assembly and the current high emphasis on quality and reliability of printed circuit assemblies have created a requirement for microanalysis of fine pitch solder joints in manufacturing situations. Of particular interest are metallographic analysis, detection of solder joint defects and mechanical strength testing of solder joints. Much has been published in the literature on the results of such evaluations in specific applications but little has been available on procedures for use in the microanalysis itself, particularly for fine pitch solder joints. Detailed procedures for fine pitch solder joint microanalysis, which the authors have verified down to 0.5 mm (0.02 in.) lead pitches, are presented. In particular, the authors present procedures for metallographic examination of tin‐lead and tin‐lead‐silver solder joints. In addition, test parameters are given for a repeatable technique of fine pitch solder joint mechanical strength testing that allows mechanical strength measurements to be obtained from almost every lead on a fine pitch surface mount IC package.

This paper aims to examine the formal and informal workplace learning of professional chefs. In particular, it considers chefs’ learning strategies and outcomes as well as the barriers to and facilitators of their workplace learning.

The methodology is based on in-depth, face-to-face, semi-structured interviews with 12 executive chefs from a variety of restaurant types. Chefs were asked questions that focused on how they learned, the learning outcomes that they experienced and factors that inhibited or facilitated their learning.

Findings suggest that the strategies, outcomes, barriers and facilitators experienced by professional chefs are similar in many respects to those of other occupational/professional groups. However, there were some important differences that highlight the context of chefs’ workplace learning.

The sample, which is relatively small and local, focuses on one city in Canada, and it is limited in its generalizability. Future research should include a national survey of professional chefs.

Using a qualitative approach, this in-depth study adds to the literature on workplace learning, strategies, outcomes, barriers, facilitators and context factors by addressing a relatively understudied profession.

The relationship between religious belief and spousal choice in Nepal is examined, looking at how the importance that individuals place on their own religious faith influences their decision either to allow their parents and other relatives to arrange a marriage for them or to initiate their own love marriage. How the importance attached to religious faith within the individual’s family and neighborhood affects this decision, and how education modifies the relationship between religion and spousal choice are also looked at.

Ordinary least squares regression models are used to examine the relationship between spousal choice and key independent variables. Interaction terms are used to examine how education may moderate the relationship between personal, family, and neighborhood religious salience and spousal choice.

It is found that the effect of one’s neighbors’ faith operates differently based on one’s own level of education. The “moral communities” thesis is used to theorize that in neighborhoods where religion is regarded as very important, individuals need to expend more effort to maintain respectability, adhering to tradition by having arranged marriages. In neighborhoods where religion is less important, the weaker demands made by the “moral community” render individuals more free to choose their own spouses. For highly educated individuals, the effect of their neighbors’ religious belief is considerably reduced.

As Nepalis become more educated, they not only move out of the sphere of family influence, as discussed in previous research, but also away from being influenced by their neighbors.

The purpose of this article is to introduce, describe, and critically examine the IBM and Hewlett‐Packard PANOSE systems of (electronic) font classification. Microsoft's TrueType Font (TTF) file format allows font developers the option of classifying their fonts according to one or both systems, and writing that information into a special location in the TTF file for use by other software.

A comprehensive survey of 13,000 TTF files was examined for information about their use of either classification system.

The classification systems are intended to help perform font substitution, as used when (part of) a document asks to be displayed in a font that is not present on the user's computer system, in which case the next nearest font is automatically chosen. However, of the nine sources of font compendia examined, only three had supplied adequate information about their fonts’ classifications in order to make this process workable. The other six sources had almost no coverage. When a font was classified by both classification systems, the two systems mapped poorly on to each other, suggesting that at least one system must be ill‐specified. PANOSE, the more detailed and slightly more popular system, showed poor internal consistency.

Sampling of the universe of fonts was opportunistic, and avoided expensive font developers who may be more conscientious adopters of the classification systems. The reliance on historic secondary data means that it is not always possible to distinguish between limitations of the systems per se and limitations of the users of the systems. This article's arguments are based on data derived from difficult‐to‐picture distinctions.

Fonts are rarely classified at the source of manufacture or distribution. To compensate for this shortcoming, software tools are required that can classify TTF files at the point of use (i.e. on one's own system) and fill in the information which is missing from the TTF files found there. Furthermore, a better classification of fonts is required, in particular one that does justice to the variety and richness of display fonts. This should break free from the hard‐to‐perceive minutiae of traditional, historically‐derived methods. Instead, it should be psychologically grounded in the distinctions that people (i.e. the users) see in fonts, rather than those taught to graphic designers.

Provides an examination of font classification in TTF files from three angles and calls for an empirically‐driven font classification.

This study aims to investigate how art events can enrich novice visitors by transforming their practices.

This research uses an interpretive case study of the art exhibition “1/1/1/1/1” in the Oppenheim gallery in Wroclaw. It draws on multiple sources of evidence, namely, novice visitors’ interviews, observation including photo studies and content analysis of art-makers’ mediation sources. This study is an example of contextual theorizing from case studies and participatory action research with researchers as change agents.

The evidence highlights that aesthetic values and experiences are contextual to practices and are transformable into other values. The findings illustrate the role of practice theory in studying how art-makers inspire the transformation of practices, including values driving the latter.

The findings provide implications for transformations of co-creating contextual values in contemporary visual art consumption and customer experience management.

Practical implications to arts organizations are also provided regarding cultural mediation conducted by art-makers. Exhibition makers should explain the meanings of the particularly visible artefacts to allow visitors to develop a congruent understanding of the meanings. The explanations should not provide ready answers or solutions to the problem art-makers suggest to rethink.

The social implication of our findings is that stakeholders in artistic ventures may undertake adequate, qualified and convergent actions to maintain or transform the defined interactive practices between them in co-creating contextual aesthetic values.

The study provides new insights into co-creating values in practices in the domain of contemporary art exhibitions by bringing the practice theory together with an audience enrichment category, thus illustrating how novice visitors get enriched by transforming their practices led by contextual values of “liking” and “understanding”.

This study aims to evaluate casino-hotel visitors’ tourism experiences which consist of multiple dimensions, and test their joint effects on visitors’ positive emotions and satisfaction. The findings are expected to reveal how multi-dimensional tourism experiences could shape visitors’ positive emotions, and empirically support positive emotions as the mediator between tourism experiences and satisfaction in the context of casino hotels.

A quantitative survey was conducted for this study. In all, 500 valid questionnaires were collected at four major casino hotels in Macao. Respondents were Chinese tourists who visited casino hotels in June. A structural model was developed and tested to understand the relationships between multi-dimensional tourism experiences, positive emotions and satisfaction.

Positive emotions were identified as “light pleasure” and “intense fun” emotions based on the context-specific measurement of casino hotels. The “light pleasure” emotions were found to be more effective in influencing respondents’ satisfaction than “intense fun” emotions. Different dimensions of tourism experiences were found to have different levels of impact on respondents’ positive emotions. The findings revealed how multi-dimensional tourism experiences influenced respondents’ positive emotions which in turn determined their satisfaction.

The findings advanced the understanding of the relationships between tourism experiences, positive emotions and satisfaction in the context of casino hotels. The two types of positive emotions identified in the study add values to the literature of casino-hotel visitors and emotional experiences. This study suggests a further investigation into the scope and measurement of each dimension of tourism experiences in different tourism settings in future research. The findings provided some practical suggestions for the management of positive emotions and tourism experiences in casino hotels.
