Résumé :

Scotland’s population history since the middle of the nineteenth century has too often been written either at a national level or as if what happened in a particular area was unique. There has been too much focus on losses, failings, or crises, and too little on successes and improvements in people’s experiences of life. There were multiple demographic Scotlands, linked to the diversity of the country’s economy, geography, and cultures, and many successes as well as failures. The book sets Scottish demography in a wider British and Western European framework and shows how patterns and trends from the past influence the present and the future demography of the country. Scotland’s outstandingly detailed published reports, many hitherto hardly used, are briefly described

Résumé :

For over sixty years, understanding the causes of multiannual cycles in animal populations has been a central issue in ecology. This book brings together ten of the leaders in this field to examine the major hypotheses and recent evidence in the field, and to establish that trophic interactions are an important factor in driving at least some of the major regular oscillations in animal populations that have long puzzled ecologists.

Résumé :

This book is a quantitative exposition of our current understanding of the dynamics of plant and animal populations, with the goal that readers will be able to understand, and participate in the management of populations in the wild. The book uses mathematical models to establish the basic principles of population behaviour. It begins with a philosophical approach to mathematical models of populations. It then progresses from a description of models with a single variable, abundance, to models that describe changes in the abundance of individuals at each age, then similar models that describe populations in terms of the abundance over size, life stage, and space. The book assumes a knowledge of basic calculus, but explains more advanced mathematical concepts such as partial derivatives, matrices, and random signals, as it makes use of them. The book explains the basis of the principles underlying important population processes, such as the mechanism that allow populations to persist, rather than go extinct, the way in which populations respond to variable environments, and the origin of population cycles.The next two chapters focus on application of the principles of population dynamics to manage for the prevention of extinction, as well as the management of fisheries for sustainable, high yields. The final chapter recapitulates how different population behaviors arise in situations with different levels of density dependence and replacement (the potential lifetime reproduction per individual), and how variability arises at different time scales set by a species’ life history.

Résumé :

The prevalence and persistence of Huntington’s disease (HD) is crucially informed by the causative mutation. Diagnostic and predictive testing has enabled a new era of epidemiologic study of HD, whereby only those who carry an expanded CAG repeat are included in such measures. In Western populations, estimated prevalence of the disease is higher following the introduction of genetic testing, and prevalence may also be increasing in absolute terms. There are worldwide differences in the prevalence of HD by ethnicity and population, which may be accounted for in part by genetic diversity of the CAG repeat and the surrounding haplotype. HD is endemic to all populations, but is most common in populations of European ancestry in which specific disease haplotypes are found. New mutations maintain HD in a population, and genetic differences by population may contribute to differences in the de novo mutation rate.

Résumé :

Jails and prisons share population management challenges with hotels: what beds are available meeting explicit requirements for which individuals? The management of large facilities and systems must incorporate ways to recognize a wide variety of safety and clinical demands in real time. Levels of security risk, medical, mental health and addictions treatment needs, and sex offender status, among others, must all be taken into account in placement decisions. Gang management and protective custody are added security factors that require consideration. Much of the work of population management is done at the time of admission into a facility. Court documents are reviewed and prior records retrieved. Custody, medical, and (where indicated) mental health staff interview the inmate on intake. Demographics, aliases, and criminal history are detailed. In a jail, the emphasis is on safety and basic medical/ mental health needs. On intake into a prison, additional concerns include educational activities, programming, and vocational needs. Increasing integration of evidence-based systems will likely occur in the future. This chapter discusses such pragmatic issues, particularly in the context of psychiatric management challenges these issues present.

Texte intégral

Résumé :

Population Dynamics fills the gap between the classical supply-side population theory of Malthus and the modern demand-side theory of economic demography. In doing so, author Cyrus Chu investigates specifically the dynamic macro implications of various static micro family economic decisions. Holding the characteristic composition of the macro population to always be an aggregate result of some corresponding individual micro decision, Chu extends his research on the fertility-related decisions of families to an analysis of other economic determinations. Within this framework, Chu studies the income distribution, attitude composition, job structure, and aggregate savings and pensions of the population. While in some cases a micro-macro connection is easily established under regular behavioral assumptions, in several chapters Chu enlists the mathematical tool of branching processes to determine the connection. Offering a wealth of detail, this book provides a balanced discussion of background motivation, theoretical characterization, and empirical evidence in an effort to bring about a renewal in the economic approach to population dynamics. This welcome addition to the research and theory of economic demography will interest professional economists as well as professors and graduate students of economics.

Résumé :

Research in public health approaches trust as a component of social cohesion, a characteristic of the social context in which an individual is embedded. This article discusses the theoretical mechanisms why living in a trusting environment might be associated with better health outcomes. A conceptual dilemma in health studies is that individual trust perceptions overlap with the personality trait of “cynical hostility” (from the field of psychology). Multi-level studies help to distinguish between the health effects of cynical distrust (an individual characteristic) and trustworthiness of the environment. I review the empirical studies linking trust and health outcomes. To date, trust has been examined as a contextual feature of residential neigborhoods and workplaces. Future research needs to strengthen causal inference.

Texte intégral

Résumé :

This chapter examines the complexities of assessing the merits and drawbacks of wildlife rehabilitation. Wildlife rehabilitation is often costly, and the resulting benefits differ depending on whether one’s interest is in the welfare of individual animals or conserving populations. Two examples of this dilemma include the rehabilitation of oiled sea otters following the Exxon Valdez spill in Prince William Sound, Alaska, and the rehabilitation of stranded sea otter pups in central California. In the first example, substantial financial investment resulted in little or no benefits for population conservation. In the second example, the potential for population-level benefits is context dependent: in populations near carrying capacity the conservation impacts are negligible, whereas in isolated, low-density populations rehabilitation and release can be an effective conservation tool. Wildlife rehabilitation is valued by people for various reasons, but recognizing and acknowledging the difference between individual and population welfare is an important step toward effective wildlife conservation.

Résumé :

Human population growth, along with technological development and levels of consumption, is a key driver of our devastating impact on the environment. This must be acknowledged as a matter of urgency. Otherwise, we risk bequeathing future generations a tragic choice between introducing explicitly impermissible coercive population policies, becoming incapable of securing even basic human rights, and worsening climate change and other environmental damage. However, this chapter warns against approaching questions of population from too narrow an environmental ethics viewpoint. If this debate is conducted in isolation from considerations of global justice, there is a real danger of advocating policies that are plausible on the surface but impermissible when assessed in terms of their implicit impact on individual human lives.

Résumé :

Population genetics is an inherently quantitative discipline. Because the focus of population genetics studies is usually on abstract concepts like the frequencies of genetic variants over time, it can at first glance be difficult to conceptualize and appropriately visualize. As more and more quantitative models and methods have become established in the discipline, it has become necessary for people just entering the field to quickly develop a good understanding of the many layers of complex approaches, so as to correctly interpret even basic results. An unfortunate side effect of the widespread implementation of ready-to-use quantitative software packages is that some facets of analysis can become rote, which at best might lead to implementation without the full understanding of the user and at worst, inappropriate application leading to misguided conclusions. In this book a “learning by doing” approach is employed to encourage readers to begin developing an intuitive understanding of population genetics concepts. The analytical software R, which has increasingly been the program of choice for early exposure to basic statistical programming, is freely available online, has cross-platform compatibility (Windows, Mac, and Linux all support distributions of R), and offers the potential for hands-on implementation by the students, in addition to using pre-packaged functions.

Résumé :

This chapter provides description and interpretation of the two major, well-documented episodes of Arctic-wide migrations. The Paleo-Inuit (also called Paleoeskimo or Arctic Small Tool tradition) migration began around 3,200 B.C., with penetration of the central Arctic by highly mobile, small-scale hunter-gatherer groups. By around 2,500 B.C., the entire eastern Arctic had been peopled by cultures known as Pre-Dorset, Saqqaq, and Independence I. The Thule Inuit migration began around A.D. 1200, when complex maritime-oriented groups from the western Arctic initiated an extremely rapid population movement, spanning the North American Arctic within a generation. The chapter considers the timing and nature of each migration episode, as well as the motivating factors which have been proposed for them, including climate change, social or economic hardship, and acquisition of specific resources such as bowhead whales or metal.

Résumé :

It is estimated that more than 500,000 women annually experience a mental illness during pregnancy. Although approximately a third of these women will be prescribed medication, the majority receives no treatment, partly because ethical challenges to including pregnant women in research protocols have impeded studies necessary to establish maternal and fetal effects of medication, appropriate dosing, and the relative risks of undertreated mental illness. Because mental illness is a frequent complication of pregnancy (particularly anxiety and depression), clinicians will be called upon to ethically navigate uncertain treatment recommendations with sensitivity to patient values. The following discussion reviews the history of current guidelines to research with pregnant women, common clinical presentations of women experiencing mental illness in the perinatal context, and relevant ethical frameworks to inform patient care.

Texte intégral

Résumé :

Inbreeding is reduced and genetic diversity enhanced when a small isolated inbred population is crossed to another unrelated population. Crossing can have beneficial or harmful effects on fitness, but beneficial effects predominate, and the risks of harmful ones (outbreeding depression) can be predicted and avoided. For crosses with a low risk of outbreeding depression, there are large and consistent benefits on fitness that persist across generations in outbreeding species. Benefits are greater in species that naturally outbreed than those that inbreed, and increase with the difference in inbreeding coefficient between crossed and inbred populations in mothers and zygotes. However, benefits are similar across invertebrates, vertebrates and plants. There are also important benefits for evolutionary potential of crossing between populations.

Texte intégral

Résumé :

The biological diversity of the planet is being rapidly depleted due to the direct and indirect consequences of human activity. As the size of wild animal and plant populations decreases and fragmentation increases, inbreeding reduces fitness and loss of genetic diversity reduces their ability to adapt to changes in the environment. Many small isolated populations are going extinct unnecessarily. In many cases, such populations can be genetically rescued by gene flow from another population within the species, but this is very rarely done. This book provides a practical guide to the genetic management of fragmented animal and plant populations.

Texte intégral

Résumé :

Both at national and international level, the right to reproduce and form a family has considerable personal and social implications. The policies that underpin the regulatory approach in this area need careful consideration for their supporting values and principles. While regulation of reproductive decisions may be direct or indirect, it is virtually universal. Reflection on the importance of the decision whether or not to reproduce, irrespective of the sophistication (or not) of the techniques used to effect it, demands attention to the human rights guaranteed by national laws and international agreements. This remains the case whether or not the decision concerns an individual, a couple, or a nation. Thus, both individual reproductive choices and policies on population control must be measured against human rights norms. As regulation is generally based on policy decisions, it is also important to explore how policy is made and the assumptions that underpin it.

Texte intégral

Résumé :

Building the Population Bomb examines how human population came to be understood as a problem in the twentieth century, how it became an object of intervention for governments, scientists, and nongovernmental organizations, and how some forms of intervention got coded as legitimate while others were recognized as coercive. It traces the emergence and growth of two scientific perspectives on population from the 1920s to the present. The first, rooted in the natural sciences, considered the world’s population as a whole in relation to natural resources. The second, rooted in the social sciences, considered national population growth rates in relation to economic growth. These two perspectives converged briefly after World War II, convincing world leaders that population growth posed a barrier to economic development and a threat to worldwide peace and environmental integrity. The book documents how this overpopulation consensus attracted vast sums of money to demography and population control, and teases out the differences between population control, birth control, and family planning. It concludes with the fracturing of this consensus at the end of the 1960s, constituting the factions that structure today’s debates over whether the world’s population is growing too quickly or not quickly enough, and over what should be done about it. The book documents how population growth came to take the blame for the world’s most complex and pressing problems, and how efforts to solve “the population problem” have diverted attention and resources from the pursuit of economic, environmental, and reproductive justice.

Résumé :

Population movements can affect security in a variety of ways. Aside from altering a society’s overall balance of population and physical resources, they exert a considerable influence on the institutions of society—the state, elite recruitment and social status, the military, labor organizations and peasant villages—in a way that undermines political and social order. The consequences of population movements for security can also be seen in differential population growth and migration, differential aging of different populations, and issues of resource allocation and climate change. The work of T. R. Malthus in the early nineteenth century advanced the argument that more people would put an undesirable burden on societies, and weaken them. Julian Simon turned the Malthusian argument on its head with his claim that people were the “ultimate resource,” and that the more people were around to work on solving the globe’s problems, the more likely it was that powerful solutions would be found. The debate between Malthusians, represented by Paul Ehrlich, and Cornucopians, represented by Simon, from the 1960s to the 1990s was primarily about the impact of population on economic growth. In the 1990s, a new direction emerged in the debate on population and security. This was the argument that population growth would lead to local shortages of critical resources such as farmland, water, and timber, and that these could trigger internal conflicts and even civil wars. These conflicts arise only where states and economies are relatively weak and unable to respond to population growth.

Texte intégral

Résumé :

The effects of genetic drift usually assume an idealized population of constant size. This chapter shows how the population size for such an idealized population can be replaced with an effective population size for populations with age structure, unequal sex ratios, a history of expansion or contraction, inbreeding, and population subdivision. These demographic features impact the entire genome more or less equally. A relatively recent understanding is that selection at a site can dramatically reduce the local effective population size experienced by nearby linked sites (the Hill-Robertson effect). This can arise from background selection to remove deleterious new mutations or from selective sweeps wherein favorable new mutations are driven toward fixation. The Hill-Robertson effect is a general way to describe the fact that selection at a site makes selection are other linked sites less efficient, and, therefore, more neutral. This chapter discusses the implications of this finding for genome structure.
