Human fatigue is a major risk factor in transportation that contributes, directly or indirectly, to a large number of traffic accidents. Though many studies have investigated fatigue-inducing factors in transportation to manage human fatigue more efficiently, there are limited studies related to vessel traffic service (VTS). To fill this gap, this work aims to determine the key causal factors and symptoms of human fatigue with a focus on VTS operations. Achieving this aim is hindered by the problems of no standard definition of task-related fatigue and limited data sources. To solve these problems, this paper proposes a novel definition of task-related human fatigue, a task-driven approach for identifying causal factors and a causal network-based approach for selecting key causal factors. Twelve key causal factors of human fatigue in VTS were identified and analysed. In addition, it was found that VTS operators suffered from multidimensional fatigue, especially physical fatigue. The results provide a foundation and future directions for designing interventions to manage human fatigue.

The psychology of forgiveness originated from the creative and important work on the development of justice initiated by Piaget in 1932 and extended by Kohlberg in 1969. The scientific study of forgiveness is quite new, having emerged in print in 1989, with an examination of the developmental progression in children’s, adolescents’, and adults’ thinking about the necessary conditions for them to offer forgiveness to another person. In this chapter, the authors first review the definition of forgiveness, followed by this early cognitive work. They then turn to a discussion of the measurement of forgiveness correlates of forgiveness. The practical application of this construct is seen in the development of forgiveness therapy and forgiveness education, which the authors discuss in light of the empirical findings. Future directions for forgiveness studies are considered.

Over the past decade, there has been a growing interest in lighting research on the effects of the recently discovered melanopsin receptor (also referred to as the intrinsically photosensitive retinal ganglion cell) and its impacts on health and vision. Presently, there is not a generally accepted metrology for dealing with the spectral response of the melanopsin receptor as applied to both lighting and vision research. A proposition to handle this issue from a vision science perspective has been presented in 2014 in the journal Trends in Neurosciences and from a more lighting perspective in 2017 in Lighting Research and Technology. These propositions are complex, and do not retain the CIE standard definition of a lumen. In this paper, we propose an approach based on effective watts and melanopic/photopic ratios that is both simpler and more closely aligned with CIE standard unit definitions. In addition, we include some practical examples of how such ratios are accessible now, and can be used for both lighting and vision research as well as applications.

AbstractUnder Chapter VII of the Charter of the United Nations, the Security Council has the unique authority to make decisions that are binding on member states. However, the lack of a standard definition of what makes a Security Council resolution "a Chapter VII resolution" has caused disagreement regarding the status of several resolutions. This is unfortunate as the international community should never have to doubt whether a Security Council resolution is in fact adopted under Chapter VII or not. It is also unnecessary. This article addresses this problem by proposing a definition of Chapter VII resolutions, based on two criteria referred to as "Article 39 determinations" and "Chapter VII decisions". On the basis of the proposed definition, the article describes and analyses a dramatic increase in the use of Chapter VII during the post-Cold War era. It concludes that as Chapter VII has come to constitute the majority of Security Council resolutions in recent years, the resort to Chapter VII no longer signifies exceptional determination and resolve, which it did during the Cold War; instead Chapter VII today implies business as usual. An appendix lists all Chapter VII resolutions from 1946–2008.

The authors review evidence and suggest future directions for research on the learning patterns of disadvantaged children. After a detailed description of a specific case of research, some implications for educational policy are discussed. The authors take issue with James S. Coleman's definition of the concept of "equal educational opportunity"and advance an alternative definition. The problem of achieving a useful definition of the term "disadvantaged"is addressed throughout the paper.

Tongue Thrust

The purpose of the present paper is to present evidence to support the following hypotheses: (1) there is a relationship between tongue thrust and malocclusion, and it is probably a reciprocal one; (2) tongue thrust may yield spontaneously to nonthrusting patterns; (3) if tongue thrust does not yield spontaneously to nonthrusting patterns, some form of treatment should be considered; (4) if myofunctional therapy is the treatment of choice, its timing with respect to patient age, developmental factors, and orthodontic treatment should be an individual matter. The need for more definitive research is described. In order for such research to be meaningful, a standard definition of tongue thrust is required. Such a definition is proposed.

Second language (SL) teacher educators tirelessly teach others how to teach. But how often do we actuallydefineteaching? Without explicit definitional activity on this fundamental concept in second language teaching (SLT), it remains implicit and intuitive – the opposite of clear, productive understanding.I therefore explore the question, ‘What is teaching?’ in this paper. First, I establish the claim that the SLT literature rarely defines teaching explicitly, in part because of its technical ‘how-to’ focus. Second, I offer a heuristic definition of teaching asevolutionarily adaptive behavior(TEAB) – as existing in humans because it enables adaptation to varied and complex ecosocial circumstances. In contrast, animals have quite modest adaptive powers, so it may come as a surprise that TEAB is not uniquely human. Therefore, third, I review research comparing animal and human teaching in order to help us understand the latter better. Fourth, I describe teaching as studied by anthropologists – as it varies across human groups. Formal teaching is relatively rare from an anthropological perspective, and relatively recent at that. Fifth, I employ the results of this definitional exercise to exploratorily examine what happens in SLT classrooms. Finally, I discuss implications and future directions for the ideas presented here and conclude.

Business To Business

This research paper provides a detailed evaluation of the business concepts in Electronic Commerce (E-Commerce). The concept of E-Commerce defines the exchange of goods and services with monetary value between consumers and companies. E-Commerce is a web-based catalogue whereby buyers can possibly place order and sellers possibly accept payments. E-Commerce incorporates two forms of business: Business-to-Business (B2B) and Business-to-Consumer (B2C), which provides a definition of the commerce transactions between enterprises, such as between the wholesalers and the manufacturers or the retailers. B2C E-Commerce provides enterprises with the model which allows businesses to deliver purchasers to the relevant merchants and achieve from the commission rewards given by the merchants. This paper evaluates two forms of business with relation to management of Virtual Enterprises (VE) in the field of E-Commerce. The paper will end with an analysis of VE before projecting future directions for health of B2B and B2C in business.
