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
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
Building a Web‐based e‐library may be the most important thing a library ever does. An important role for librarians in all types of libraries is the planning and/or building of Web‐based e‐libraries. Offers a practical discussion of developing and implementing a collection plan for building Web‐based e‐libraries. The starting point for developing any collection plan is an assessment of the function of and need for an information collection and the audience it will serve. Discusses some guidelines and practical strategies on where and how to find, identify, evaluate and select appropriate Web‐based information resources. Focuses on Web‐based information resources rather than other electronic information resources such as CD‐ROM or fee‐based databases that have been discussed extensively in recent literature.

Abstract
Purpose
Organizations often fail to utilize managerial personnel effectively for leadership development and succession planning systems, and many execute these critical practices through separate human resource functions that shift the responsibility for leadership development away from line managers. The purpose of this article is to present a best practices model for optimal development of the leadership pipeline and a series of practical recommendations for organizations.
Design/methodology/approach
A group of 30 CEOs and human resource executives across 15 best practice organizations were asked via semi‐structured interviews to describe the content and delivery of their respective organizations' leadership development and succession planning practices.
Findings
Analysis of interview data indicated that best practice organizations effectively integrate leadership development and succession planning systems by fully utilizing managerial personnel in developing the organization's mentor network, identifying and codifying high potential employees, developing high potentials via project‐based learning experiences and manager‐facilitated workshops, establishing a flexible and fluid succession planning process, creating organization‐wide forums for exposing high potential employees to multiple stakeholders, and establishing a supportive organizational culture.
Research limitations/implications
The interview data are drawn from a relatively small number of executives and from a single industry, which may limit the overall utility of the findings.
Originality/value
This study offers needed empirical support for the value of integrating leadership development and succession planning practices through utilization of managerial personnel. Management development practitioners will benefit from assessing their respective organizations' current practices vis‐à‐vis those discussed here, while scholars may utilize the best practices model for generating further research on the role of managerial personnel in talent management systems.

Abstract
Noel Tichy, who ran GE’s Leadership Development Center, is currently director of the Global Leadership Program at the University of Michigan’s Business School. His teaching model posits that CEO’s must be intimately involved in teaching their teams’ leaders. The basic premise is that companies are successful to the extent that they have leaders at all levels of the organization. Any institution that invests in the development of leaders at all levels is going to get ahead of its competition. It is a principal job of the leader to help develop the next generation of leaders. Unfortunately, many leading companies do not build good leadership pipelines because their leaders do not do the teaching of their own managers. An essential element for a leader to develop the next generation is to present a teachable point of view about how he/she believes they should run the organization. Also needed is a clear idea of what your want to teach them: ideas, product services, distribution channels, customer segments, and values. Leadership is about focusing on human capital as the organization’s most important asset. Unfortunately, many companies make only 10 percent of the investment they should make on development of their people and most of it is spent in the wrong ways. A better approach is to make 80 percent of the development investment be on‐the‐job life experiences. The other 20 percent can be potentially leveraged with very high impact development experiences. If you sit around and read business school cases for three weeks, you’re getting about 20 percent of what you could if you engaged people in action learning real projects. Developing leaders requires a rethinking of the leadership pipeline. You look for those career points where you can leverage the 80% with high impact development, and then you have to build teaching into every single management process.

Abstract
Purpose
The purpose of this research is to account for the internationalization of restaurants. The conceptual framework of upper echelons theory is applied to identify the demographic determinants of internationalization among chief executive officers (CEOs).
Design/methodology/approach
Data from 30 restaurant firms for the period 1999-2013 were collected from a variety of sources, primarily Compustat and Execucomp, based on Standard Industrial Classification (SIC) code 5812, the annual 10-K and public information. A panel feasible generalized least squares model was used as the main instrument of analysis.
Findings
The findings indicate that the CEO gender and share ownership negatively affect the internationalization of restaurant companies, whereas size, the extent of franchising, the type of restaurant and stock options positively affect the degree of internationalization. Additionally, an inverted U-shaped relation exists between CEO tenure and the degree of internationalization.
Practical implications
The presented information may provide shareholders and boards of directors with valuable guidelines regarding the assignment of appropriate managers depending on the extent to which their companies are pursuing internationalization strategies.
Originality/value
Most studies in hospitality sectors have focused only on accounting-based measures to explain strategic decision-making, although proponents of upper echelons theory have argued that CEO attributes influence strategic decisions/changes. This study contributes to the literature on hospitality by identifying the effects of CEO characteristics on internationalization decisions.

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.

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
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.
