How to Judge Globalism

Abstract: Globalization is often seen as global Westernization. On this point, there is substantial agreement among many proponents and opponents. Those who take an upbeat view of globalization see it as a marvelous contribution of Western civilization to the world. There is a nicely stylized history in which the great developments happened in Europe: First came the Renaissance, then the Enlightenment and the Industrial Revolution, and these led to a massive increase in living standards in the West. And now the great achievements of the West are spreading to the world. In this view, globalization is not only good, it is also a gift from the West to the world. The champions of this reading of history tend to feel upset not just because this great benefaction is seen as a curse but also because it is undervalued and castigated by an ungrateful world.

Chapter 1 Social justice and the distribution of income

Abstract: Publisher Summary This chapter reviews the bearing of theories of social justice on the analysis and evaluation of income distribution and related features of economic inequality. The assessment of income distribution involves both descriptive and prescriptive issues and the ideas of the way social justice influence both. The connection is immediate in the case of normative analysis, because the concepts of social justice can be central to ethical norms for assessing the optimality or acceptability of the distributions of income. But the connections with descriptive and predictive issues can be, ultimately, no less important. People's attitudes toward, or reactions to, actual income distributions can be significantly influenced by the correspondence—or the lack thereof—between (1) their ideas of what is normatively tolerable and (2) what they actually see in the society around them. The ideas of social justice can sway actual behavior and actions. In assessing the likelihood of discontent or protest or disapproval or the political feasibility of particular policies, which are primarily descriptive and predictive issues (rather than prescriptive ones), it can be useful, indeed crucial, to have some understanding of the ideas of justice that command respect in the society in question. A complete theory of justice need not insist on a complete ranking of all possible alternatives. The resilient presence of competing grounds of justice has strong implications on the discipline of inequality evaluation in general and of the assessment of income distribution in particular.

On Happiness and Human Potentials: A Review of Research on Hedonic and Eudaimonic Well-Being

Abstract: ▪ Abstract Well-being is a complex construct that concerns optimal experience and functioning. Current research on well-being has been derived from two general perspectives: the hedonic approach, which focuses on happiness and defines well-being in terms of pleasure attainment and pain avoidance; and the eudaimonic approach, which focuses on meaning and self-realization and defines well-being in terms of the degree to which a person is fully functioning. These two views have given rise to different research foci and a body of knowledge that is in some areas divergent and in others complementary. New methodological developments concerning multilevel modeling and construct comparisons are also allowing researchers to formulate new questions for the field. This review considers research from both perspectives concerning the nature of well-being, its antecedents, and its stability across time and culture.

Agricultural sustainability and intensive production practices

Abstract: A doubling in global food demand projected for the next 50 years poses huge challenges for the sustainability both of food production and of terrestrial and aquatic ecosystems and the services they provide to society. Agriculturalists are the principal managers of global useable lands and will shape, perhaps irreversibly, the surface of the Earth in the coming decades. New incentives and policies for ensuring the sustainability of agriculture and ecosystem services will be crucial if we are to meet the demands of improving yields without compromising environmental integrity or public health.

Dynamics of dark energy

Abstract: We review in detail a number of approaches that have been adopted to try and explain the remarkable observation of our accelerating universe. In particular we discuss the arguments for and recent progress made towards understanding the nature of dark energy. We review the observational evidence for the current accelerated expansion of the universe and present a number of dark energy models in addition to the conventional cosmological constant, paying particular attention to scalar field models such as quintessence, K-essence, tachyon, phantom and dilatonic models. The importance of cosmological scaling solutions is emphasized when studying the dynamical system of scalar fields including coupled dark energy. We study the evolution of cosmological perturbations allowing us to confront them with the observation of the Cosmic Microwave Background and Large Scale Structure and demonstrate how it is possible in principle to reconstruct the equation of state of dark energy by also using Supernovae Ia observational data. We also discuss in detail the nature of tracking solutions in cosmology, particle physics and braneworld models of dark energy, the nature of possible future singularities, the effect of higher order curvature terms to avoid a Big Rip singularity, and approaches to modifying gravity which leads to a late-time accelerated expansion without recourse to a new form of dark energy.
