Abstract
Purpose
The ability to measure and assess “quality” is essential in building and maintaining a safe and effective transportation system. Attaining acceptable quality outcomes in transportation projects has been a reoccurring problem at both the federal and state levels, at least partially, as a result of poorly developed, inefficient or nonexistent quality assurance/quality control (QA/QC) processes. The purpose of this paper is to develop and implement a new QA/QC process that focuses on a novel double-bounded performance-related specification (PRS) and corresponding pay factor policy that includes both lower and upper quality acceptance and payment reward boundaries for bridge concrete.
Design/methodology/approach
The authors use historical data to design different payment scenarios illustrating likely industry responses to the new PRS, and select the single scenario that best balances risk between the agency and industry. The authors then convert that payment scenario to a pay factor schedule using a search heuristic and determine statistical compliance with the PRS using percent-within-limits (PWL).
Findings
The methodology offers an innovative approach for developing an initial set of pay factors when lifecycle cost data are lacking and the PRS are new or modified. An important finding is that, with a double-bounded PRS, it is not possible to represent pay factors using the simplified table PWL currently employed in practice because each PWL value occupies two separate positions in the payment structure – one above the design target and one below it. Therefore, a more detailed set of pay factors must be employed which explicitly specify the mean sample value and the design target. The approach is demonstrated in practice for the Agency of Transportation in state of Vermont.
Research limitations/implications
The authors demonstrate a novel approach for developing a double-bounded PRS and introduce a payment incentive/disincentive policy with the goal of improving total product quality. The new pay factor policy includes both a payment penalty below the contracted price for failing to meet a specified performance criterion as well as a payment premium above the contracted price that increases as the sample product specification approaches an “ideal” design value. The PRS includes both an upper and lower acceptance boundary for the finished product as opposed to only a lower tail acceptance boundary, which is the traditional approach.
Practical implications
The authors illustrate a research collaboration between academia and a state agency that highlights the role academic research can play in advancing quality management practices. The study involves the use of actual product performance data and is operational as opposed to conceptual in nature. Finally, the authors offer important practical insights and guidance by demonstrating how a new PRS and pay factor policy can be developed without the use of site-specific historical lifecycle cost (LCC) data that include detailed manufacturing, producing and placement cost data, as data related to product performance over time. This is an important contribution, as the development and implementation of pay factor policies typically involve the use of historical LCC data. However, in many cases, these data are not available or may be incomplete.
Social implications
With the new PRS and pay factor schedule, the Agency expects shrinkage and cracking on bridge decks to decrease along with overall maintenance and rehabilitation costs. A major focus the new PRS is to actively involve industry partners in quality improvement efforts.
Originality/value
The authors focus on a major modification to an existing QA/QC process that involves the development of a new PRS and an associated pay factor policy undertaken by the Vermont Agency of Transportation. The authors use empirical data to develop a novel double bounded PRS and payment schedule for concrete and offer unique operational/practical insight and guidance by demonstrating how a new PRS and pay factor policy can be developed without the use of site-specific historical LCC. Typically, PRS for in-place concrete have only a lower tail acceptance boundary.

Abstract
Purpose
This paper introduces a novel quality measure, the percent-within-distribution, or PWD, for acceptance and payment in a quality control/quality assurance (QC/QA) performance specification (PS).
Design/methodology/approach
The new quality measure takes any sample size or distribution and uses a Bayesian updating process to re-estimate parameters of a design distribution as sample observations are fed through the algorithm. This methodology can be employed in a wide range of applications, but the authors demonstrate the use of the measure for a QC/QA PS with upper and lower bounds on 28-day compressive strength of in-place concrete for bridge decks.
Findings
The authors demonstrate the use of this new quality measure to illustrate how it addresses the shortcomings of the percent-within-limits (PWL), which is the current industry standard quality measure. The authors then use the PWD to develop initial pay factors through simulation regimes. The PWD is shown to function better than the PWL with realistic sample lots simulated to represent a variety of industry responses to a new QC/QA PS.
Originality/value
The analytical contribution of this work is the introduction of the new quality measure. However, the practical and managerial contributions of this work are of equal significance.

Abstract
Purpose
This paper aims to describe a method of teaching that is based on Novak's concept‐mapping technique.
Design/methodology/approach
The paper shows how concept mapping can be used to measure prior knowledge and how simple mapping exercises can promote the integration of teachers' and students' understandings in ways that are meaningful.
Findings
The concept‐mapping method facilitates quick and easy measures of student knowledge‐change so that teachers can identify the parts of the curriculum that are being understood and those that are not. This is possible even among very large student groups in the 50‐minute slots that are allocated to so much teaching in higher education.
Research limitations/implications
Concept mapping is discussed in the wider context of student learning style. The styles literature has been criticised because it tends to encourage undue labelling of people or behaviours. The approach described here also uses “labels” to typify learning (using the terms non‐learning and rote or meaningful learning to identify different qualities of change).
Originality/value
The difference in this approach is that terms are attached to empirical measures of learning outcome, not to personal or psychological styles. Concept mapping makes learning visible so that the actual quality of the learning that has occurred can be seen and explored. Using concept mapping in the course of teaching means that learning is no longer a complex and intractable process, measurable only by proxy, but an observable phenomenon.

Abstract
In the last four years, since Volume I of this Bibliography first appeared, there has been an explosion of literature in all the main functional areas of business. This wealth of material poses problems for the researcher in management studies — and, of course, for the librarian: uncovering what has been written in any one area is not an easy task. This volume aims to help the librarian and the researcher overcome some of the immediate problems of identification of material. It is an annotated bibliography of management, drawing on the wide variety of literature produced by MCB University Press. Over the last four years, MCB University Press has produced an extensive range of books and serial publications covering most of the established and many of the developing areas of management. This volume, in conjunction with Volume I, provides a guide to all the material published so far.

Abstract
Purpose
Trust and commitment are the central tenets in building successful long‐term relationships in the online retailing context. In the absence of physical interaction between the buyer and the seller, how websites can gain the trust of the buyers and deliver on the promises made have become central issues in online customer relationship management. This paper aims to re‐examine the commitment‐trust theory (CTT) of relationship marketing in the online retailing context. It seeks to theorize the antecedents and consequences of commitment and trust in the online context and identify how CTT can be adapted in a digitized business environment.
Design/methodology/approach
Modified constructs and their measures are developed to understand the antecedents and the outcomes of commitment and trust. Survey data from British online customers (n=651) are used to test CTT hypotheses with structural equation modelling.
Findings
The study suggests a significant modification to the traditional CTT model in the online environment. Privacy and security features of the website along with shared values are the key antecedents of trust, which in turn positively influences relationship commitment. Behavioural intentions of customers are consequences of both trust and commitment. The relationship termination cost has a negative impact on customer commitment.
Research limitations/implications
The paper identifies interesting differences between the original work by Morgan and Hunt and the findings presented, but basically concludes that the commitment‐trust theory applies to online retailing.
Originality/value
Contributions of this study in re‐examining the CTT model of relationship marketing in an online context are manifold. This paper proposes a modified model to understand the role of consumer trust and commitment in a digitized environment. The modified constructs and measures truly reflect the dynamism of online business. The extended CTT model can provide better insight into managing customer relationships in online retailing.

Abstract
Purpose
The purpose of this paper is to test flow as a construct distinctly separate from its antecedents, and the resulting impact on brand attitudes and purchase intent within realistic online shopping three-dimensional virtual environments (3-DVEs).
Design/methodology/approach
This research utilizes a field study, combined with a survey research design of 348 3-DVE participants.
Findings
The findings reveal that flow is not a unidimensional construct but rather, a mental state that should be measured separately from its antecedents, with the possibility that certain antecedents may be more relevant than others in different activities. Furthermore, the authors received strong support for the overarching hypothesized model separating the nine dimensions associated with engagement in an activity as antecedents of flow, which, in turn, influences brand attitude and thereafter purchase intention.
Research limitations/implications
This study was limited to one type of activity within one 3-DVE but is balanced by the difficulty in gaining access to organizations and computer-mediated environments of this type for examining such phenomena.
Practical implications
Businesses using 3-DVEs to market brands should focus their efforts on creating highly enjoyable experiences that result in the feeling of a loss of sense of time for the participants in order to ultimately positively influence purchase intentions.
Originality/value
Prior research focused on fantasy-based, game-oriented environments, while also neglecting to test all elements of flow, examining “similar to flow” constructs or measuring flow as a unidimensional construct.

Abstract
The most serious barrier to achieving a “forgiving building” is the cost of its special building systems. The library is increasingly becoming a “hi tech” and “smart” building. A sophisticated facility is required to support current collections and the emerging electronic and optical technologies that will occupy (and perhaps dominate) the future library. It is far less expensive to provide the capacity to support future components at the time of initial construction than to subsequently renovate a building to provide needed capacities at a later date. The real challenge for librarians is to convince those who fund library construction that the “forgiving building” is the least expensive alternative in the long run.

Abstract
The Bureau of Economics in the Federal Trade Commission has a three-part role in the Agency and the strength of its functions changed over time depending on the preferences and ideology of the FTC’s leaders, developments in the field of economics, and the tenor of the times. The over-riding current role is to provide well considered, unbiased economic advice regarding antitrust and consumer protection law enforcement cases to the legal staff and the Commission. The second role, which long ago was primary, is to provide reports on investigations of various industries to the public and public officials. This role was more recently called research or “policy R&D”. A third role is to advocate for competition and markets both domestically and internationally. As a practical matter, the provision of economic advice to the FTC and to the legal staff has required that the economists wear “two hats,” helping the legal staff investigate cases and provide evidence to support law enforcement cases while also providing advice to the legal bureaus and to the Commission on which cases to pursue (thus providing “a second set of eyes” to evaluate cases). There is sometimes a tension in those functions because building a case is not the same as evaluating a case. Economists and the Bureau of Economics have provided such services to the FTC for over 100 years proving that a sub-organization can survive while playing roles that sometimes conflict. Such a life is not, however, always easy or fun.

Abstract
Purpose
The paper aims to investigate how a tablet's design features, namely, its navigation design and visual appearance, influence users' enjoyment, concentration and control, when using tablets for problem-solving, and thereafter how their core flow experiences impact their perceived performance and efficiency with problem-solving.
Design/methodology/approach
This study uses a field survey approach to engage 87 participants in a decision sciences class to use eTextbooks and a few other associated educational apps including CourseSmart app for e-notes and highlighting, sketchbook app and a calculator app in tablets to resolve class problems at a large US university.
Findings
This study finds that the tablet's interface design features (navigation and visual appearance) make users engrossed in their problem-solving processes with perceived enjoyment, concentration and control. This, in turn, impacts their perceived performance and efficiency. Moreover, visual appearance plays the most significant role in arousing users' affective emotions (i.e. enjoyment), while interface navigation is crucial to engage users' deep concentration (i.e. cognition) and control for problem-solving.
Practical implications
Modern tablets are being used widely in various sectors. More in-depth user flow experience design associated with tablet use for problem-solving contexts should be further advocated in order to provide more engaging and meaningful flow experiences to users.
Originality/value
This study shows that the design of the tablet interface can engage users in problem-solving processes in both affective and cognitive ways. It provides valuable insights on tablet interface design for problem-solving.
