This thesis presents a comprehensive analysis of the global health impacts of polycyclic aromatic hydrocarbons (PAHs) in ambient air, conducted on the basis of a high-resolution emission inventory, global chemical transport modeling, and probabilistic risk assessment. One of the main strengths of the thesis is the concentration downscaling process, which provides a linkage between emissions and exposure concentrations at a comparatively high resolution. Moreover, by focusing on individual susceptibility, the thesis proposes an instrumental revision of current risk assessment methodology and argues that, if individual susceptibility were not taken into consideration, the overall risk would be underestimated by 55% and the proportion of highly vulnerable populations would be underestimated by more than 90%.

How does academic writing vary between educational settings, disciplines, and cultures? How do different approaches to knowledge affect academic writing? Teaching Academic Writing combines research and practice to explore the questions that instructors may have about academic writing in the second language classroom. Whether for writing teachers new to the second language classroom or ESL teachers new to academic writing instruction, this textbook provides an accessible and detailed survey of the key issues and ideas that shape the teaching of academic writing to ESL students today. Chapters address a full range of critical topics, including the context and process of academic writing, needs analysis, teaching approaches, the interrelationship between writing and vocabulary, intercultural perspectives, feedback, and assessment. Each chapter includes Classroom Implications, tasks and techniques for teaching, and some possible exercises to use with students. Chapters begin with thought-provoking questions and end with a section designed to help users consider their own beliefs and classroom practices. This textbook also includes suggestions for practical resources that can be used in the academic writing classroom.
