To address the safety concerns generated by truck crashes occurred in big cities, this paper analyzes the zip code tabulation area (ZCTA)-based truck crash frequency across four temporal intervals – morning (6:00–10:00), mid-day (10:00–15:00), afternoon (15:00–19:00), and night (19:00–6:00) in New York City in 2010. A multivariate conditional autoregressive count model is used to recognize both spatial and temporal dependences. The results prove the presence of spatial and temporal dependencies for truck crashes that occurred in neighboring areas. Built environment attributes such as various types of business establishment density and traffic volume for different types of vehicles, which are important factors to consider for crashes occurred in an urban setting, are also examined in the study.

There is significant amount of literature tackling different issues related to the port industry. The present chapter focuses on a single business unit of seaports aiming at the documentation of works related to container terminals.

An effort to review, collect and present the majority of the works present in the last 30 years, between 1980 and 2010, has been made in order to picture the problems dealt and methods used by the authors in the specific research field. To facilitate the reader, studies have been grouped under five categories of addressed problems (productivity and competitiveness, yard and equipment utilization, equipment scheduling, berth planning, loading/unloading) and four modelling methodologies (mathematics and operations research, management and economics, simulation, stochastic modelling).

The analysis shows that most works focus on productivity and competitiveness issues followed by yard and equipment utilisation and equipment scheduling. In reference to the methodologies used managerial and economic approaches lead, followed by mathematics and operations research.

In reference to future research, two fields have been identified where there is scope of significant contribution by the academic community: container terminal security and container terminal supply chain integration.

The present chapter provides the framework for researchers in the field of port container terminals to picture the so far works in this research area and enables the identification of gaps at both research question and methodology level for further research.

In an attempt to promote sport employees’ well-being, the purpose of this paper is to examine the more traditional constructs of psychological capital (i.e. hope, efficacy, resiliency and optimism) and to feature the inclusion of authenticity, an often overlooked construct, among sport employees.

This conceptual paper is designed to create an expanded sport employee psychological capital construct, labeled A-HERO, and a subsequent theoretical model to improve their well-being.

In detailing a conceptual model of A-HERO for well-being, the model includes and explains the relationships among sport employee antecedents (i.e. sport employee identification, pride and passion), an organizational contextual variable (person–organization fit), and an important employee and organizational outcome (i.e. employee well-being) in contemporary sport organizations.

A-HERO offers a necessary first step for future theoretical research and empirical applications to improve sport employees’ well-being.

By elucidating the role of authenticity at work with traditional psychological capital constructs in the current sport industry, this paper stimulates sport business and management scholars to validate empirically the A-HERO construct and examine proposed relationships for an improved prediction of sport employees’ well-being.

Purpose – Driver distraction and other forms of driver inattention remain significant road safety problems. The purpose of this chapter is to explore recent developments in theoretical and empirical research on driver distraction and inattention and provide the reader with a sense for, and understanding of, the key issues.

Methodology – Key references from the literature are reviewed and discussed.

Findings – First, we discuss one way of conceptualising the distinction between driver distraction and other forms of inattention, as well as the mechanisms which may underlie these forms of inattention. Second, we underscores how driver distraction may derive from a plethora of sources, and how the potential for performance degradation deriving from driver interaction with these sources may be moderated by a range of factors. Third, we review recent literature on the types of impairments in driving performance and safety associated with driver distraction. Fourth, we outline recent literature on driver distraction and inattention in the realm of highly automated vehicles that will drive the transport future. Finally, we discuss some promising strategies aimed at preventing and mitigating the impact of driver distraction.

Research implications – There are many gaps in the driver distraction literature that need to be addressed. In addition, further research needs to be undertaken to examine the role of driver distraction in the realm of highly automated vehicles.

Practical implications – The findings point towards of a range of injury prevention countermeasures that have potential to prevent and mitigate driver distraction.

The study aims to find new anticorrosive components from a plant source, namely, Pachysandra terminalis Sieb. et Zucc. (P. terminalis), a traditional medicinal shrub predominantly used by Tujia people.

Because phenolic components from plants are known for its numerous values in several fields, the corrosion inhibitive ability of P. terminalis extract was analyzed by electrochemical studies (polarization, electrochemical impedance spectroscopy) and surface examination (by scanning electron microscopy [SEM], energy-dispersive X-ray spectroscopy [EDX] and atomic force microscopy [AFM]).

The examination of total phenolic content (TPC), total flavonoids content (TFC) and individual phenols (UHPLC) showed the presence of 85.21 mg/g (TPC), 25.38 mg/g (TFC), protocatechuic acid (62.10 µg/g), gentisic acid (60.21µg/g), rutin (50.12 µg/g), kaempferol (46.58 µg/g) and p-Coumaric acid (42.35µg/g) . The polarization study shows that the maximum shift is (16 mV), imposing a mixed mode of inhibition, dominantly anodic. The surface morphology studies by SEM, EDX and AFM confirmed the adsorption of phytochemical components on the low carbon steel surface blocking the active sites.

The study unveils the inhibitive nature of P. terminalis, preventing aggressive attack by 0.5 M HCl on low carbon steel. This also exhibits few phenols present in methanolic leaf extract which may be the role player of corrosion inhibition.

This chapter models the number of ferry round trips per day in order to make suggestions for future ferry schedules for an island – in this case Bornholm. Calendar effects, including the effect of moving religious holidays, as well as the overall annual level of economic activity, are taken into account. The model for the number of round trips per day is also applicable to the number of passengers per day. If the number of passengers (and arrivals) per day is forecast, this may be used as a basis for forecasting daily, weekly and monthly activity levels for service providers at the destination, including service providers in the accommodations sector. For islands, data for all passengers to/from the destination may be available (ferries and airlines). Based on these daily, weekly or monthly passenger numbers, both domestic and international numbers may be modelled and forecast. Other destinations may model and forecast daily, weekly and monthly international arrivals by air in order to support decisions at the destination site.

Assigning business process activities to agents (human or automated) for their performance or supervision is a critical issue in business process management. Role‐based approaches are commonly used to specify work assignment policies, with roles defined as collections of capabilities and privileges required to perform job functions. The purpose of this paper is to address the activity assignment problem through a competency‐based approach. In this context, an ontology‐based competency model is developed to assist in identifying the competencies that exist in an organization and the competencies required, by workflow activities and in performing a competency gap analysis as a prerequisite for domain‐specific user development through competency‐based training.

An approach for developing a business process activity assignment policy based on an ontology‐based competency model is presented. This model is also used to define domain‐specific training courses that enable users meet the competency requirements of process activities. In broad terms, the approach consists of the following steps: identification of the competencies required in order to perform the various activities involved in each business process and definition of roles based on these competencies; identification of the competencies acquired in the organization and assignment of users to roles; performance of competency gap analysis to identify the missing user competencies for role playing and identification of user development needs; and development of competency‐based training scenarios intended to fill the user competency gaps.

An experimental implementation of the ontology‐based competency model proposed in the banking domain provided a fine‐grained role structure that was based on the competencies required by business process activities, and a user‐to‐role assignment that closely matched the competencies required for role playing, and brought forward missing user competencies that pointed to required user training needs.

The proposed ontology‐based competency model fulfils the need for a sustained work assignment approach based on user roles. To this end, roles and users are defined as collections of required and acquired competencies, respectively. A novel approach based on ontology‐based competency ontologies was also developed to fill required but missing user competencies.
