This book analyses the links between migration and the composition, structure, and geographic distribution of populations. It discusses the evolution of population redistribution policies in Brazil, and examines internal migration between the 1930s and the 1980s.

Over the last decade, the study of shark biology has benefited from the development, refinement, and rapid expansion of novel techniques and advances in technology. These have given new insight into the fields of shark genetics, feeding, foraging, bioenergetics, imaging, age and growth, movement, migration, habitat preference, and habitat use. This pioneering book, written by experts in shark biology, examines technologies such as autonomous vehicle tracking, underwater video approaches, molecular genetics techniques, and accelerometry, among many others. Each detailed chapter offers new insights and promises for future studies of elasmobranch biology, provides an overview of appropriate uses of each technique, and can be readily extended to other aquatic fish and marine mammals and reptiles. Including chapter authors who were pioneers in developing some of the technologies discussed in the book, this book serves as the first single-source reference with in-depth coverage of techniques appropriate for the laboratory and field study of sharks, skates, and rays. It concludes with a unique section on Citizen Science and its application to studies of shark biology. This is a must-read for any marine biologist or scientist working in the field of shark biology, as well as marine biology students and graduates.

This book introduces the fundamentals of research methods and how they apply to the discipline of urban and regional planning. Written at a level appropriate for upper-level undergraduate and beginning master’s level students, the text fills a gap in the literature for textbooks on urban planning. Additionally, the book can be used as a reference for planning practitioners and researchers when analyzing quantitative and qualitative data in urban and regional planning and related fields. The volume does not assume advanced knowledge of mathematical formulas. Rather, it begins with the essentials of research methods, such as the identification of the research problems in planning, the literature review, data collection and presentation, descriptive data analysis, and report of findings. Its discipline-specific topics include field research methods, qualitative data analysis, economic and demographic analysis, evaluation research, and methods in sub-disciplines such as land use planning, transportation planning, environmental planning, and housing analysis. Designed with instruction in mind, this book features downloadable materials, including learning outcomes, chapter highlights, chapter review questions, datasets, and certain Excel models. Students will be able to download review questions to enhance the learning process and datasets to practice methods.

The Seventh National Population Census (NPC) results show that China's population structure has undergone profound changes. While the rates of education penetration and urbanization continue to rise, issues such as population aging and low fertility rates have become prominent. Population is the core factor influencing economic growth, and its structural changes will bring numerous opportunities and challenges for China's future economic development. Currently, most of the research on the economic effects of population structure mainly focus on constructing a certain static panels to analyze certain demographic factors, lacking consideration of the wholeness and correlation aspects of population structure. Moreover, the design of models seldom incorporate the intrinsic dynamics and convergence of economic growth. Therefore, it is of great significance to construct a dynamic panel model and systematically study the impact of various demographic factors on regional economic growth and convergence, so as to understand and grasp the demographic changes in China and promote the coordinated development of regional economy. Based on a comprehensive review of the theoretical literature, this book first conducts a systematic analysis of the spatial and temporal evolution patterns of China's national and regional population structure and regional economic development. Second, it identifies the mechanism through which population structure affects regional economic growth and convergence and proposes research hypotheses. Subsequently, based on the neoclassical economic growth convergence model, a dynamic model is constructed to examine the influence of population structure on regional economic growth and convergence. Using panel data on population structure and economic growth from 31 provinces, autonomous regions, and municipalities directly under the central government, an empirical analysis is conducted using the SYS-GMM method. Additionally, a heterogeneity analysis is conducted with samples from the eastern, central, and western regions. Furthermore, taking into account the reality of shortened spatial and temporal distances and intensified population mobility between regions, a spatial econometric model is constructed to analyze the spatial spillover effect of population structure on regional economic growth. The current research theory for interfacial loess landslides is relatively lagging behind. Therefore, this book provides a detailed theoretical study on the failure mechanism and calculation model of interface type loess landslides, and provides a clear theoretical derivation process and application methods. The research process involves interdisciplinary research in soil mechanics, elastic-plastic mechanics, fracture mechanics, structural mechanics, theoretical mechanics, and other disciplines, which not only reflects the multi-angle nature of research issues, but also reflects the multi-scale nature of research issues. The conclusions of the study as follows: changes in the gender structure of the population do not have a significant impact on the speed of national and regional economic growth. On the other hand, an increase in the gender ratio in the western region may promote economic growth convergence. Secondly, population aging can reduce labor supply and savings rate, inhibit innovation, thereby impeding regional economic growth and convergence. The influence of the rate of urbanization on economic growth shows an inverted U-shaped pattern. Initially, urbanization promotes economic growth, but excessive urbanization may hinder it. The eastern region has the highest urbanization rate and experiences an inverted U-shaped impact on economic growth, whereas the central and western regions benefit from linearly positive effects of urbanization. Moreover, the improvement of urbanization rate is one of the most important factors promoting regional economic growth convergence. The enhancement of the population's educational level can promote total factor productivity and human capital in the country as a whole and each region, thereby driving economic growth. It also stands as one of the most crucial factors promoting regional economic growth. Additionally, considering spatial factors, the aging of the population has a positive effect on the interaction of regional economic growth. Based on the above conclusions, this book proposes the following policy recommendations: First, adhere to the concept of gender equality and alleviate the pressure caused by the "marriage squeeze". Second, improve the pension system and vigorously develop the "silver economy". Third, promote the coordinated development of new urbanization and prevent "pseudo-urbanization" and "counter-urbanization". Fourth, implement the three major strategies of innovation-driven, science and education revitalization, and talent power. Fifth, strive to promote the upgrading of the employment structure and give full play to the important role of the tertiary industry in absorbing labor.

Originally published in 1986, this volume brings together geographical modelling of population change and demographic analysis of population structures and pattern. These 2 strands are interwoven in 3 key review chapters that summarize the study of spatial and temporal patterns of population, the modelling of spatial populations and the estimation of population processes. Findings reported include: An account of demographic transition; an exposé of the myth of ‘no fertility rises’ in the developing world in the 20th Century; a theory of population accounting; predicting migration flows for a system of regions; microsimulation methods to model population change; and demographic and economic processes integrated in an urban region model.
