Abstract
Over the last century, governments throughout the established democracies have increasingly sought to regulate land markets via all manner of interventions. Such policies have typically been defended on the ‘market failure’ grounds of orthodox welfare economics. Absent government action, it is argued, price signals will not be reflective of the relevant opportunity costs, owing to the prevalence of externality and public goods problems in the market for land.

Abstract
Introduces gas chromatography (GC) a key analytical technique in the food industry. It enables complex organic substances to be separated and identified quickly and cheaply. Substances to be analysed by GC must be volatile, i.e. readily pass into the gas phase. The substance to be analysed is vaporized and moved through a long column by an inert carrier gas. The column is filled with a packing material covered with an involatile liquid. The molecules of each substance in a mixture will become distributed between the gas and the liquid. The more volatile a substance the longer it will be moving with the carrier gas, and the quicker it will emerge from the column. Some substances must be extracted from the food analysis by GC, e.g. fatty acids from triglycerides. Others, such as alcohols, can be injected directly into the column.

Abstract
In almost all aspects of social life government intervention seems much more pervasive and intrusive today than ever before – at least in many of the Western countries. Governments seem year by year to consume still more resources and to regulate the details of the actions and interactions of their citizens still further.

Abstract
Students with extensive supports needs (ESN) often require pervasive and intensive supports to access the full benefits of educational programming. In this chapter, the authors describe the application of both established and innovative technologies for promoting equitable access and opportunity for these students. They provide guidance for the use of technology across the areas of academic instruction, social communication, behavior supports, daily living, and employment.

Abstract
Comorbidity of attention deficit hyperactivity disorder (ADHD) and reading disabilities (RD) is greater than what would occur by chance. Considering the well-documented adverse impact of both ADHD and RD on development, the presence of both conditions may lead to particularly poor outcomes for affected people. This chapter, which reviews 43 research studies carried out in the last decade that have focused on the link between ADHD and RD, is divided into two broad nuclei of contents. First, studies are described that contribute information about characteristics of the comorbid phenotype. Second, studies related to procedures directed toward evaluation and intervention in this problem are analyzed. The review carried out does not make it possible to extract definitive results on the exact nature of ADHD and RD comorbidity or, even less, reach conclusions about its causes. However, the literature-based evidence shows a cognitive profile of ADHD+RD characterized by failure of various functions that can produce more severe functional deficits and worse neuropsychological, academic, and behavioral outcomes. Furthermore, the analysis of the set of results from the studies shows a limited efficacy of pharmacological and psychopedagogical treatments, and highlights the need for continued research on this topic. From a clinical and educational standpoint, the conclusions derived from this review underline the importance of performing an exhaustive evaluation of children and adolescents with symptoms of ADHD and/or RD, in order to be able to plan interventions with greater possibilities of success in each case.

Abstract
Student-led project-based teams are widely used by faculty but do we really understand the process that students experience as a result of participating in a team? This study sought to understand the team process by examining leadership practices exhibited by assigned leaders and their team culture. Using a mixed-methods case study design it was found that students perceived team leaders to be strongest in the leadership practice-enable others to act described as fostering collaboration and sharing power and weakest in the leadership practice-encourage the heart described as recognizing individual contributions and celebrating team successes. Two of the teams were identified as a clan culture and the third team was determined to be a market culture. It was recommended that instructors who use teams to enrich learning examine the relationship between specific team cultures and enhanced team performance.

Abstract
This introductory chapter synthesises an extensive and hot debate revolving around the role of precautionary doctrine in tourism fields. Although the industry faces serious risks and dangers, terrorism – just after 9/11 – situates as the most dangerous hazard and as a challenge for policymakers and practitioners. We have reviewed the pros and cons of the most important academic schools that focused on tourism security and risk perception theory. The urgency is given in creating a bridge between theory and practice in order to articulate the policies to the nature of each risk. Today risk perception theory lacks a robust methodological background that invariably led to a gridlock. Whether the demographic school advances in the multivariable correlation between class, ideology, income or education with risk perception, the sociological school lays the foundations towards a much deeper understanding of the impacts of risks in society. Rather, the radical turn – coming from a Marxist tradition – focuses on the limitations of risk perception theory. Finally, authors who form the psychological tradition, as stated in this chapter, highlight on the complexity of emotions and the inner world. All chapters in this book aim to provide fresh practical cases that reflect the socio-cultural background of the four continents.

Abstract
The scourge of terrorism has situated as one of the major risks and concerns for policy makers and authorities in the Western hemisphere. The attacks to WTC marked not only a first attack in the US soil but the prelude of a set of attacks perpetrated in the European urban metropolises. Over years, the classic literature punctuated on the negative impact of terrorism in the tourist destination. Recently, some voices have questioned this assumption holding that under some conditions the tourist demands recover to the earlier levels before the crisis. This chapter discusses critically not only the differentiation between risks and threats but also the different faces of terrorism. We also propose a model based on three dimensions: terrorism as a risk, terrorism as a threat and terrorism as a worry. As a conceptual model, the resulted hypotheses and ideas should be empirically validated in next layouts.
