It has been recognized for some time that the liberalization of trade policies has had deleterious impacts on the world’s natural environment. The rapid expansion of globalized goods and services continues to create a human footprint with longlasting environmental consequences (White 2010). It is a footprint that represents rapid human activity and with it has come new commercial opportunities, not only for global businesses but also for organized criminal networks. Both the acceleration and by-products of global trade have created new markets as well as underground economies. As the opening quotation reveals, transnational environmental crime must become a policing priority as organized criminal...

Metacognitive theory provides a novel conceptual framework to understand the development and maintenance of psychopathology. It emphasizes the importance of stored knowledge guiding the individual’s plan for coping with heightened cognitive-affective arousal. According to the metacognitive model individuals experience strong affective responses and engage in a process of metacognitive appraisal and initiation of coping responses in the pursuit of cognitive-affective self-regulation. This chapter outlines the details of this theoretical approach as applied to substance misuse and the metacognitive treatment components aimed at interrupting the selection of maladaptive coping responses.

Commercial success in the music industry is obviously related to one’s ability to use musical artisanship as a basis for generating profits and to accumulate substantial wealth. That may seem fairly straightforward, but commercial success is an elusive concept that is continuously negotiated within the industry to determine both what should be considered “success” as well as how it should be measured. This entry discusses commercial success in the popular music industry and strategies used to achieve it.

“The challenge today is not just retaining talented people, but fully engaging them, capturing their minds and hearts at each stage of their work lives” (Kaye & Jordan-Evans, 2003, p. 11). Engaged employees produce positive work outcomes such as increased productivity satisfaction, and reduced turnover (Kahn, 1990, 1992; Saks, 2006). Engaged employees also impact on customers and co-workers’ positive experiences such as increased customer satisfaction (Wagner & Harter, 2006). Further, engaged employees demonstrate higher levels of trust in management and share more positive experiences with co-workers than disengage employees (Payne, Cangemi, Fuqua, & Muhleakamp, 1998). Past studies show that having a high proportion of engaged employees increases organizational performance, such as profitability and reputation (Wagner & Harter, 2006; Fleming & Asplund, 2007; Ketter, 2008). Having experienced the benefits of having engaged employees, organizations have become more aware of this issue and have been focusing on facilitating engagement climate within workplaces. Recently, an interest in positive psychology, instead of negative aspects of human behaviours, has become a focus for both scholars and practitioners. The trend towards positive psychology has led to the emergence of the concept of work engagement(Chughtai & Buckley, 2008). This article reviews literatures in the area of positive psychology and psychological stress, and discusses how organizations can increase work engagement among their organizational members. The remainder of this article is organised in four sections. First, we define work engagement as used in this article and psychological outcomes of work engagement. Second, we identify ways to increase work engagement among employees. Following this, we further discuss how gender roles influence individuals’ engagement at work. The final sections conclude the paper with a discussion of the practical implications.

Newell (1985, 1986) identified the importance of interacting constraints on the emergent behaviours of learners or performers in sport as they assemble functional states of movement organisation in achieving task goals. Constraints, related to the person, task and environment, were defined as ‘boundaries or features that limit motion of the entity under consideration at any moment in time’ (Newell, 1986, p.347). Personal (or organismic) constraints include factors such as individual anthropometrics (height, weight, and limb lengths), fitness (e.g., strength, speed, aerobic capacity, and flexibility), mental skills (e.g. concentration, confidence, emotional control and motivation), perceptual and decisionmaking skills (e.g., recognising patterns of play, anticipation by reading the movements of opponents) and personality factors (e.g., risk taking or conservative behaviours). Newell (1986, p.350) distinguished between general environmental constraints, such as gravity, ambient temperature, natural light and altitude and task constraints, which are task specific and concerned with the goals of a specific activity. More recently, socio-cultural constraints (e.g., family support, cultural expectations and access to facilities) have also been considered as environmental constraints. Application of the constraints framework to the study of sport performance has led to task constraints being defined to include factors such as rules of games, equipment used, boundary playing areas and markings, nets and goals, the number of...

The insulated rail joint (IRJ) is an essential component in a track circuit that controls the signaling system. Failure of IRJs leads to improper functioning of the signals,with potential for catastrophic results. Therefore, IRJs are regarded as safety-critical sections of rail network; hence, all of their components must be maintained in pristine design condition.

The present article gives an overview of the reversible addition fragmentation chain transfer (RAFT) process. RAFT is one of the most versatile living radical polymerization systems and yields polymers of predictable chain length and narrow molecular weight distribution. RAFT relies on the rapid exchange of thiocarbonyl thio groups between growing polymeric chains. The key strengths of the RAFT process for polymer design are its high tolerance of monomer functionality and reaction conditions, the wide range of well-controlled polymeric architectures achievable, and its (in-principle) non-rate-retarding nature. This article introduces the mechanism of polymerization, the range of polymer molecular weights achievable, the range of monomers in which polymerization is controlled by RAFT, the various polymeric architectures that can be obtained, the type of end-group functionalities available to RAFT-made polymers, and the process of RAFT polymerization.

In policy terms, community media are known as the “third sector” of the media. The description reflects the historical expectation that community media can fulfill a need not met by the commercial and public service broadcasters. A defining element of this “need” has been the means to production for nonprofessionals, particularly groups not represented in the mainstream media. The historical construction of community media reveals production to be a guiding principle; both a means and an end in itself. This chapter examines the various rationales underpinning community media production, including empowerment, media diversity, and the independent producer movement. Using case studies from youth media, the chapter critiques producer-centric models of community media. In the contemporary media environment, production alone cannot meet the social needs that community media were established to address. Instead, I propose a rationale that combines both production and consumption ethics.

The changing and challenging conditions of the 21st century have been significantly impacting our economy, society and built and natural environments. Today generation of knowledge—mostly in the form of technology and innovation—is seen as a panacea for the adaptation to changes and management of challenges (Yigitcanlar, 2010a). Making space and place that concentrate on knowledge generation, thus, has become a priority for many nations (van Winden, 2010). Along with this movement, concepts like knowledge cities and knowledge precincts are coined as places where citizenship undertakes a deliberate and systematic initiative for founding its development on the identification and sustainable balance of its shared value system, and bases its ability to create wealth on its capacity to generate and leverage its knowledge capabilities (Carrillo, 2006; Yigitcanlar, 2008a). In recent years, the term knowledge precinct (Hu & Chang, 2005) in its most contemporary interpretation evolved into knowledge community precinct (KCP). KCP is a mixed-use post-modern urban setting—e.g., flexible, decontextualized, enclaved, fragmented—including a critical mass of knowledge enterprises and advanced networked infrastructures, developed with the aim of collecting the benefits of blurring the boundaries of living, shopping, recreation and working facilities of knowledge workers and their families. KCPs are the critical building blocks of knowledge cities, and thus, building successful KCPs significantly contributes to the formation of prosperous knowledge cities. In the literature this type of development—a place containing economic prosperity, environmental sustainability, just socio‐spatial order and good governance—is referred as knowledge-based urban development (KBUD). This chapter aims to provide a conceptual understanding on KBUD and its contribution to the building of KCPs that supports the formation of prosperous knowledge cities.

Helplines are services where callers can request help, advice, information, or support. While such help is usually offered through telephone helplines, web chat and email helplines are becoming increasingly available to members of the public. Helplines tend to offer specialized services, such as responding to computer software queries, or medical and health issues, or seeking information about natural disasters. Further, they may be aimed at particular populations such as children and young people. The earliest research investigating discourse in calls to helplines in social interactional research began in the 1960s with Sacks’ early work on calls to a suicide prevention center. Since then interactional research has produced a wealth of understandings into the mundane and institutional interactional practices through which help is sought and delivered. In addition to discussing the breadth of research into helplines, this entry explores the relationship between philosophies and interactional practices of helpline services.

INTRODUCTION: I want to argue that understanding masculinity is an important part of understanding gender and sexuality as it relates to information and communications technologies (ICTs), specifically those under the lens of the information-systems community. In order to do this, the landscape of gender and sexuality research in general is referred to along with such research in the field of information systems (IS), with reference as necessary to masculinity studies. I will then suggest some possible areas where a more thorough going theorization may prove useful. In sum, future research might focus on the relation-ship between marginalised masculinities and the construction and consumption of is in work organisations and society…
