In December 2008, as the financial and economic crisis continued on its devastating course, a new scandal erupted. After the 1998s failure of Long-Term Capital Management, Madoff's fraud once again discredits the hedge funds industry. This scandal is, however, of a different kind. Indeed, Madoff's firm is not a standard hedge fund but a developed Ponzi scheme. By explaining Madoff's system and exploring the reasons for its collapse, this paper draws risk management lessons from this fraud, especially for operational risk management, due diligence processes, and the use of quantitative replication, regulatory, and standardizing approaches of the hedge fund industry.

Construction is a highly dynamic environment with numerous interacting factors that affect construction processes and decisions. Uncertainty is inherent in most aspects of construction engineering and management, and traditionally, it has been treated as a random phenomenon. However, there are many types of uncertainty that are not naturally modelled by probability theory, such as subjectivity, ambiguity and vagueness. Fuzzy logic provides an approach for handling such uncertainties. However, fuzzy logic alone has some limitations, including its inability to learn from data and its extensive reliance on expert knowledge. To address these limitations, fuzzy logic has been combined with other techniques to create fuzzy hybrid techniques, which have helped solve complex problems in construction. In this chapter, a background on fuzzy logic in the context of construction engineering and management applications is presented. The chapter provides an introduction to uncertainty in construction and illustrates how fuzzy logic can improve construction modelling and decision-making. The role of fuzzy logic in representing uncertainty is contrasted with that of probability theory. Introductory material is presented on key definitions, properties and methods of fuzzy logic, including the definition and representation of fuzzy sets and membership functions, basic operations on fuzzy sets, fuzzy relations and compositions, defuzzification methods, entropy for fuzzy sets, fuzzy numbers, methods for the specification of membership functions and fuzzy rule-based systems. Finally, a discussion on the need for fuzzy hybrid modelling in construction applications is presented, and future research directions are proposed.

This chapter uses Goffman’s concept of total institutions in a comparative case study approach to explore the role of psychotropic drugs in the process of transinstitutionalization.

This chapter interprets psychotropic drug use across four institutionalized contexts in the United States: the active-duty U.S. military, nursing homes and long-term care facilities, state and federal prisons, and the child welfare system.

This chapter documents a major unintended consequence of transinstitutionalization – the questionable distribution of psychotropics among vulnerable populations. The patterns of psychotropic use we synthesize suggest that total institutions are engaging in ethically and medically questionable practices and that psychotropics are being used to serve the bureaucratic imperatives for social control in the era of transinstitutionalization.

Psychotropic prescribing practices require close surveillance and increased scrutiny in institutional settings in the United States. The flows of mentally ill people through a vast network of total institutions raises questions about the wisdom and unintended consequences of psychotropic distribution to vulnerable populations, despite health policy makers’ efforts regulating their distribution. Medical sociologists must examine trans-institutional power arrangements that converge around the mental health of vulnerable groups.

This is the first synthesis and interpretive review of psychotropic use patterns across institutional systems in the United States. This chapter will be of value to medical sociologists, mental health professionals and administrators, pharmacologists, health system pharmacists, and sociological theorists.

Often new principals approach their first appointments with a high expectation to make their mark by introducing changes that would lead to school improvement. However, these expectations may be void of thoughts of how an inherited school culture may weigh on their emotions and upset their notions about principalship on a daily basis. Emerging from a multiple case study research design, in which a critical incident technique was the main source of data on new principals’ emotional experiences, the findings show that the new principals experienced predominantly negative emotions and wounding, often linked to pre-formed expectations of school members. Also, influenced by a need to protect their leadership authority, they selected which emotions to disclose versus which to suppress. These findings as drawn from a broader study conducted in Trinidad and Tobago imply a need for training and continuing professional development that would support aspirant and practising principals’ emotion regulation.
