Several recent papers presented at the annual meeting of the Transportation Research Board, Washington, D.C., and elsewhere have reported on efforts to make sustainability manageable. To this end, the papers suggested the use of indicators and performance measures to help conceptualize and operationalize sustainability for transportation-related planning and decision making. Often these studies presented frameworks that would allow sustainability indicators and measures to be included in, for example, agency strategies and practices. Moreover, some papers suggested criteria for the selection of individual indicators and performance measures. The studies, however, did not always agree on the definition of a framework or how to use one to make sustainability-based decisions, and they tended to differ on underscored aspects and concerns. The current study addressed the issue of frameworks more generically and explored what was termed a “metaframework” with a set of associated criteria to guide the framing of indicators for sustainable transportation. On the basis of an explicit framework theory, the three functions of conceptualization, operationalization, and utilization were found to provide a logical structure of complementary features with which to build indicator frameworks. Characteristics of robust indicator frameworks were evaluated in terms of their significance for the three key functions, and they were collected in a list of criteria. A review of the Brundtland Report provided an example of how a more finely grained understanding of sustainability can inform the conceptualization criterion ranking of sustainability impacts. The metaframework was intended primarily as a basis for empirical analysis and for meta-evaluation of existing practice frameworks with respect to the strength of the level of sustainability that they are likely to provide.

PurposeSupply chain agility (SCA) has recently received considerable attention in the literature and in practice. Despite its popularity, the concept of SCA seems to be vaguely defined and loosely structured. More specifically, definitional ambiguity and conceptual fragmentation have prevented the concept of SCA from reaching its full potential. The time is ripe to address these issues through a systematic literature review.Design/methodology/approachA review and synthesis of the literature on SCA was undertaken. The authors selected 56 top-tier related articles for further analysis after applying rigorous filtering procedures.FindingsThe results of the review confirm that several key themes surround SCA's definition and enablers. In addition, consensus needs to be reached in terms of its performance dimensions and measures. Accordingly, this study constructed an encompassing definition, scrutinized SCA enablers and outcomes and thus developed an original framework for SCA, providing a unique conceptual contribution. Several research directions were also addressed accordingly.Originality/valueThe novelty of this research lies in the selection of highly recognized publications. It also provides an encompassing definition of SCA, consolidates its enablers for better communication and synthesizes its performance implications.

Purpose – The purpose of this article is to encourage organizations to recognize the potential risks of retaining counterproductive employees on their payrolls and the steps they should take to prevent and/or correct the situation should it exist within their organizations. Design/methodology/approach – Literature examining a broader definition of the negligent retention doctrine, which includes employees who lack the qualifications for the positions they hold, those who are nonperformers, and/or those who exhibit toxic behaviours, and the consequences for retaining these counterproductive employees on the payroll. By using a multilayered approach, the article discusses the efforts organizations can use to identify potentially counterproductive employee behaviour and the steps the organizations should take to provide appropriate developmental strategies/programs to assist counterproductive employees, as well as, provide appropriate disciplinary action, as the situation dictates. Findings – The review highlights the potential financial drain and performance threats counterproductive employees create for organizations; offers explanations as to why counterproductive employees are often allowed to stay on the payroll; and provides suggestions for preventing the selection of counterproductive employees, for providing appropriate developmental. Practical implications – The article offers practical insights and suggestions to organizations that are interested in upholding their fiduciary responsibility to their stakeholders, while providing counterproductive employees opportunity to improve their performance/behaviours or to exit the organization. Originality/value – The article expands the definition of the negligent retention doctrine to include the often-ignored financial and emotional dangers of retaining unfit or counterproductive employees on the payroll.

Cybersecurity is an emerging field with a growing body of literature and publications. It is fundamentally based in computer science and computer engineering but has recently gained popularity in business management. Despite the explosion of cybersecurity, there is a scarcity of literature on the definition of the term ‘Cybers Security' and how it is situated within different contexts. Henceforth, this chapter presents a review of the work related to cybersecurity, within different contexts, mainly IT governance and firm performance context. The work reviewed is separated into four main categories: the importance of cybersecurity and how it is measured, corporate governance and IT governance, IT governance mechanisms, and financial performance measures.

The development of safe and dependable robots for physical human-robot interaction is actually changing the way robot are designed introducing several new technological issues. Outstanding examples are the adoption of soft covers and compliant transmissions or the definition of motion control laws that allow a compliant behavior in reaction to possible collisions, while preserving accuracy and performance during the motion in the free space. In this scenario, a growing interest is devoted to the study of variable stiffness joints. With the aim of improving the compactness and the flexibility of existing mechanical solutions, a variable stiffness joint based on the use of compliant flexures is investigated. The proposed concept allows the implementation of a desired stiffness profile and range along with the selection of the maximum joint deflection. In particular, this paper reports a systematic procedure for the synthesis of a fully-compliant mechanism used as a non-linear transmission, together with a preliminary design of the overall joint.

Sharpe’s ratio is the most widely used index for establishing an order of priority for the portfolios to which the investor has access, and the purpose of this investigation is to verify that Sharpe’s ratio allows decisions to be made in investment portfolios considering different financial market conditions. The research is carried out by autoregressive model (AR) of the financial series of returns using Sharpe’s ratio for evaluations looking over the priority of financial assets which the investor can access while observing the effects that can cause autocorrelated series in evaluation measures for financial assets. The results presented in this study confirm the hypothesis proposed in which Sharpe’s ratio allows decisions to be made in the selection of investment portfolios under normal conditions thanks to the definition of a robustness function, whose empirical estimation shows an average 73% explanation of the variance in the degradation of the Spearman coefficient for each of the performance measures; however, given the presence of autocorrelation in the financial series of returns, this similarity is broken.

PurposeSustainable mobility will be the key to the survival of mankind in the 21st century. Cities with debt-ridden and poorly managed transport systems have to change to the ever-growing demands of the public transport system. The low cost of transport has been a key factor in sustainable development for any city. This study is trying to propose a framework for the selection of sustainable transport in context to an Indian case of NCR Delhi, India.Design/methodology/approachThe present study has identified eight criteria for the selection of a sustainable transport system. Criteria for selection of sustainable transport are CO2 emissions, cost of fuel, energy efficiency, cost of maintenance, number of accidents, congestion, number of injuries and road noise. Three alternatives of transport considered for this study are state-run bus, pooled car and Shuttl (App-based buses). The analytic hierarchy process (AHP) is used to prioritize the criteria. The study has further illustrated a framework for the selection of sustainable transport based on these criteria.FindingsIt is observed that CO2 emissions are the most important criterion for a sustainable transport system. It is followed by a reduction in congestion and the number of injuries. Three alternatives of transport considered for this study are state-run bus, pooled car and Shuttl (a service provider). Shuttl has been found to be the most sustainable transport system.Research limitations/implicationsAHP is not able to capture the vagueness in decision-making. Therefore, fuzzy AHP can be considered for further detailed analysis as future scope of study in a different context of a sustainable transportation system. Major implications for policymakers and stakeholders are that development of public transport in cities should be done after considering different dimensions of sustainable operations.Originality/valueThe study has proposed a unique framework for the selection of a sustainable transport system by the public based on sustainability criteria. Findings will help policymakers in formulating strategies for developing sustainable transport system.

Growth trends in Minnesota emphasize the need to ensure that travel on highway corridors linking regional trade centers in the state is safe, reliable, and efficient. In 1999, the Minnesota Department of Transportation initiated an interregional corridor study to define a system of interregional corridors that connect important regional trade centers. Minnesota’s effort to develop the interregional corridor system, performance expectations, and principles and policies for managing and guiding development along these corridors is described. The interregional corridor system and the corresponding management principles and policies were developed in several phases: ( a) definition of regional trade centers, ( b) identification of the interregional corridor system, ( c) development of interregional corridor principles and policies, and ( d) development of a corridor management plan guide. The study developed performance measures and performance targets to identify mobility risk corridors, which are corridors that perform below target speed or have a risk of signal proliferation. Methods used at a sketch-planning level to identify priority routes and performance levels are described. The study developed a more uniform process for developing corridor management plans.

The present study examined the failure of earlier researchers to find relationships between the Test of Attentional and Interpersonal Style and behavioral measures of attentional processes. Data are presented which illustrate the attenuation in correlations as a result of improper selection of subjects. When this problem is addressed, the predicted relationships between subjective and behavioral measures of attention are obtained. Results provide additional evidence of construct validity for the Test of Attentional and Interpersonal Style.

The quality of the sustainability plans of 11 state departments of transportation (DOTs) is systematically assessed with a content analysis methodology. Analysis reveals that state DOTs that have created a sustainability plan are also likely to have developed a policy framework aligned with the principles of sustainable transportation within their plan. The quality of a sustainability plan is driven by the strength of its policy framework, including plan visions, goals, policies, strategies, and performance measures. External drivers of plan quality include the presence of a prescriptive state sustainability mandate, external funding for plan development, and the involvement of a policy entrepreneur in plan development. Prescriptive mandates and external funding bolster the quality of the plan development process and the degree to which the plan is integrated with existing policies and practices of the DOT and other agencies. A policy entrepreneur's involvement in plan development strengthens the policy framework and helps unify plan content toward a consistent vision. In addition to conclusions relating to the development of transportation sustainability plans, this study illustrates the value of systematic and objective content analyses in assessing the quality of transportation planning documents.

The importance of examining stained 1 to 2μ plastic sections by light microscopy has long been recognized, both for increased definition of many histologic features and for selection of specimen samples to be used in ultrastructural studies. Selection of specimens with specific orien ation relative to anatomical structures becomes of critical importance in ultrastructural investigations of organs such as the lung. The uantity of blocks necessary to locate special areas of interest by random sampling is large, however, and the method is lacking in precision. Several methods have been described for selection of specific areas for electron microscopy using light microscopic evaluation of paraffin, epoxy-infiltrated, or epoxy-embedded large blocks from which thick sections were cut. Selected areas from these thick sections were subsequently removed and re-embedded or attached to blank precasted blocks and resectioned for transmission electron microscopy (TEM).
