Discusses computational challenges in air quality modelling (as viewed by the authors). The focus of the paper will be on Di, the “current” state‐of‐affairs. Owing to limitation of space the discussion will focus on only a few aspects of air quality modelling: i.e. chemical integration, sensitivity analysis and computational framework, with particular emphasis on aerosol issues.

Concern about the use of zero-tolerance policies for discipline has led to a search for alternatives such as training in early-warning signs of aggressive behavior and strategies for effective classroom management in schools. This chapter examines the effectiveness of the provision of alternatives to out-of-school suspensions (OSS) in reducing the use of exclusionary discipline for minor misbehavior and the school characteristics associated with these provisions.

This analysis uses the 2008 panel from the National School Survey on Crime and Safety to explore this question for approximately 1,000 high schools. The analysis is a probit regression analysis to examine the association between the provision of alternatives to OSS, school characteristics, and the use of OSS for low-level suspensions. This analytic approach provides wide generalizability for the findings, though it does also limit an ability to identify individual school- or student-level effects.

Findings based on probit regression analysis suggest that structural characteristics of schools – beyond student characteristics – are only somewhat related to variation in the use of OSS for low-level infractions and, on average, the availability of alternatives to OSS do not strongly decrease the frequency of OSS for lower-level infractions. These findings are important in the current era of discipline policy scrutiny where schools and policy-makers are searching for alternatives to traditional suspension practices in a limited empirical evidence base.

While these alternatives hold great promise, little is known about their effectiveness in addressing behavior problems and/or reducing OSS. More importantly, even less is known about the characteristics of schools likely to enact alternatives.

Since the end of the Second World War, many spectacular advances have been made in aeronautics, thanks chiefly to the development of more powerful and economical jet engines. As to the parasitic drag of manned aircraft, progress has been confined to reducing unfavourable compressibility effects (area rule, Whitcombe bodies); methods to suppress separation have been developed but no new methods to reduce the drag resulting from turbulent boundary layers developing over the exposed surfaces have as yet found practical application.

All societies in the modern world are troubled by crime, and the general public is equally fascinated by criminals and fearful of criminal behaviour. In the United Kingdom, events such as the murders of Jack the Ripper, the Yorkshire Ripper and Harold Shipman, and the Soham tragedy, coupled with film and television programmes including Silence of the Lambs, Cracker and Crime Scene Investigation, have fuelled the public's consciousness of the criminal mind.In the fight against crime, the development of offender profiling by the FBI in the USA has further captured people's imagination. The technique was introduced to help law enforcement agencies solve serious crimes such as serial rape or murder, and to a lesser extent arson and property crime. At the heart of profiling lies the belief that by combining psychological principles with crime scene analysis, it is possible to identify the likely characteristics of a perpetrator.Although advances in crime detection are welcomed, the profiling field appears riddled with contradiction and disagreement. Social scientists argue that the discipline is unscientific due to methodologically weak research, while police officers appear sceptical about its benefits for solving crime. In Britain, profiling has witnessed both notable successes, for example Canter's profile of the serial rapist and murderer John Duffy, and dramatic failures, such as the Colin Stagg profile in the Rachel Nickell inquiry. This article reviews the offender profiling literature, examines its applicability in the legal system and identifies areas for future research.

The purpose of the chapter is to discuss the tourist experiences by tracing various perspectives and dimensions of authenticity, commodification, and McDonaldization.

The main debates on the authenticity of the tourism experiences and the commodification of the tourism product is examined. Further a relevant literature on the McDonaldization thesis is provided focusing on experiential dimensions of the tourism consumption.

Destinations rely not only on the object authenticity of their attractiveness but also strive to attract tourists by tailoring experiences that will meet high-order needs of the tourists. However, these destinations are under threat by commodification and McDonaldization due to excessive use of the resources as a result of mass tourism.

Destination managers and planners should focus on the experiences without compromising on authenticity, uniqueness, and genuineness of their destinations while refraining over-commercialization and McDonaldization of their offerings.

This chapter discusses the authenticity, commodification, and McDonaldization issues on the basis of a case study of a well-established destination.

The chapter introduces the reader to select language of human sexuality and the definitions and characteristics of some key terms related to lesbian, gay, bisexual, transgender, and questioning/queer (LGBTQ+), identifies different theoretical perspectives of human sexuality and sexual orientation, and discusses select LGBTQ+ theories and concepts in a historical context that library and information science (LIS) professionals should consider while performing their roles related to information creation–organization–management–dissemination–research processes. It helps better understand the scope of what is LGBTQ+ information and traces its interdisciplinary connections to reflect on its place within the LIS professions. The chapter discusses these implications with the expectation of the LIS professional to take concrete actions in changing the conditions that lack fairness, equality/equity, justice, and/or human rights for LGBTQ+ people via the use of information. Important considerations in this regard include the need for an integrative interdisciplinary LGBTQ+ information model, growth of a diversified LGBTQ+ knowledge base and experiences, holistic LGBTQ+ information representations, LGBTQ+ activism, and participatory engagement and inclusion of LGBTQ+ users.

Over recent years, a number of companies have committed to sharing information relating to their environmental, social and governance (ESG) activities, in response to a higher demand for transparency from stakeholders. This paper aims to explore the impact of such reporting on the financial performance of construction companies.

This paper first examines the state of non‐financial reporting of publicly‐listed construction companies on climate change, environmental management, environmental efficiency, health and safety, human capital, conduct, stakeholder engagement, governance and other matters deemed to be of concern to institutional investors. It then presents the results of an empirical study on the impact of issuing non‐financial reports and the extent of companies’ sustainability practices (represented by ESG scores) on the financial performance of the companies. Financial performance is measured via a range of financial ratios.

The paper finds that a majority of the publicly‐listed construction companies studied have low levels of reporting, while construction companies issuing non‐financial reports largely outperform those which do not in a number of selected financial ratios, although the correlation between financial performance and ESG scores is not strong.

The originality of this research lies in its use of “hard data”, and it is supported by a wide range of financial ratios; this is distinguished from the existing, largely qualitative literature.

The purpose of this paper is to consider the significance of the sources of cost of construction plant theft identified in previous studies and derive rates which can enhance proper estimation of the cost of plant theft to the construction industry. The direct and indirect costs of plant theft include replacement cost (new‐for‐old/depreciated), emergency cost, hire replacement cost, productivity loss, increased labour cost, loss of goodwill, administration cost, increased insurance premium and social cost.

The cost‐contribution of these various sources was studied, using a structured questionnaire which was administered to building contractors in the UK construction industry, to measure their opinions of the frequency and severity of the contribution of the sources to the cost of construction plant theft. The questionnaires were administered to 220 companies and 51 of them were fully completed, representing 23.1 per cent of the original sample. The responses were analysed using descriptive and inferential statistics to derive the probabilities of sources contributing to the cost of plant theft.

The results of the analysis show that the rates of contribution to the cost of plant theft varies significantly between the sources, with “loss of output” and “increased insurance premium” ranking as the top‐two costs of plant theft in the UK construction industry. The rates derived in this study can be used by contractors to reasonably estimate the cost of plant theft, especially when there is need to justify the adoption of measures that can mitigate plant theft.

This study generated rates of contribution by factors which contribute to the overall cost of theft of construction plant in the UK. These rates can provide a more reliable estimate of the cost of plant theft than current estimations which vary significantly.
