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).

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.

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.

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.

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.

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).

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.

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.

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.

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.

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.

The purpose of this article is to understand how academics in management deal with the concept of generation in the workplace. We begin by conducting an interdisciplinary literature analysis, thereby elaborating a conceptual framework concerning generational diversity. This framework consists of four levels of analysis (society, career, organisation and occupation) and three dimensions (age, cohort and event/period). We then conduct a meta-analysis using this conceptual framework to analyse papers from the management field. The results from this analysis reveal the existence of a diversity of generational approaches, which focus on the dimensions of age and cohort on a societal level. Four factors seem to explain these results: the recent de-synchronisation of generational dimensions and levels, the novelty of theoretical models, the amplification of stereotypes by mass media and the methodologies employed by researchers. In sum, this article contributes to a more realistic view of generational diversity in the workplace for both academics and practitioners.

In 1767, did Sir James Steuart predict the political and financial crises that started the French Revolution? Étienne de Sénovert, the editor and translator of Steuart’s work, seems to argue to this effect in the introduction to the first French edition of An Inquiry into the Principles of Political Economy in 1789. The visionary “prediction” set forth by Steuart was the following: if the king of France had introduced public credit, this would have changed the political balance in French political society, making it very unstable. The English and the French governments used different ways of borrowing money in 1760: the French king contracted debts with a network of financiers close to the government, while the English government borrowed on the credit markets through the intermediary of the Bank of England. The second of these methods constitutes public credit and has proved its efficiency. According to Steuart, implementing the English public credit system in France could have dangerous consequences. Landed interests and moneyed interests would compete for the control of the State. The author realized that the French nobility, the landowners, as a social and economic group would have no chance in facing such a powerful rival (the public creditors). In this chapter, the author analyzes Steuart’s “prediction” as a coherent part of his systematic and original approach to political economy. Steuart’s theories about the role of political economy and the role of “interest” are connected to his understanding of institutions. Introducing such a complex support for the value as public credit might have different consequences in France and England. Steuart thinks each country’s economy should be analyzed according to its own institutional and social context.

Steuart’s work was still relevant in 1789 for two reasons. Firstly, the author’s prediction of political antagonism between capitalists and nobility anticipated the political conflict about debt expressed by pamphleteers such as Sieyès, Mirabeau, and Clavière between 1787 and 1789. This is the context of Étienne de Sénovert’s claim: the political narrative built by the revolutionaries of 1789 (rescuing the “sacred” public debt from royal despotism) fitted Steuart’s prediction. This may have been the incentive for the translation and publication of his work in 1789 and 1790. Secondly, Steuart’s financial and monetary theory was at the heart of the project of financial reform that would lead to the assignats. Steuart’s (1767) theory of public finance and state power in 1789 provides a key to the understanding the events of the time, and to how actors tried to make sense of them. Steuart made another crucial observation about the deep effect of what he called “the modern economy” upon the power of the governments of Europe: even an absolute monarch could not damage public credit without destroying his own sovereignty.

This paper aims to assess service quality in professional football and to examine the effects of service quality and ticket pricing on satisfaction and behavioural intention. Data were collected among football fans and the results of a confirmatory factor analysis (CFA) supported the psychometric properties of the service quality model. A structural equation model (SEM) revealed that the service quality construct impacts both satisfaction and behavioural intention. Also, behavioural intention is influenced by ticket pricing and satisfaction. Managerial implications of these results are discussed and guidelines for future research are suggested.

The following classified, annotated list of titles is intended to provide reference librarians with a current checklist of new reference books, and is designed to supplement the RSR review column, “Recent Reference Books,” by Frances Neel Cheney. “Reference Books in Print” includes all additional books received prior to the inclusion deadline established for this issue. Appearance in this column does not preclude a later review in RSR. Publishers are urged to send a copy of all new reference books directly to RSR as soon as published, for immediate listing in “Reference Books in Print.” Reference books with imprints older than two years will not be included (with the exception of current reprints or older books newly acquired for distribution by another publisher). The column shall also occasionally include library science or other library related publications of other than a reference character.

Constructivist grounded theory method (GTM) as outlined by Kathy Charmaz has its explicit roots in the American pragmatism and symbolic interactionism primarily developed at the University of Chicago during the early and mid-twentieth century. Symbolic interactionism considers people as active and interpretative agents who co-construct selves, identities, meanings, social actions, social worlds, and societies through interactions. Charmaz argues that symbolic interactionism is an open-ended theoretical perspective that fosters studying action, process, and meanings, with a focus on how people co-construct and negotiate meanings, orders, and actions in their everyday lives. In this chapter, I argue that constructivist GTM, including its theory-method package built upon symbolic interactionism and the Chicago School tradition, can be further combined with the new sociology of childhood to study children's social worlds and negotiated meanings, orders, and actions.
