Los Eventos que Dividieron la Historia del Mundo
Esta obra colectiva refleja una exhaustiva exploración de diversos aspectos relacionados con el panorama laboral global, enfocándose en la evolución del proteccionismo del trabajador, nuevas formas de protección social y desafíos emergentes en el ámbito laboral. Se examinan las tendencias del proteccionismo laboral, destacando la reducción de la jornada laboral en Colombia y las perspectivas del contrato colectivo en Italia post-epidemia. Se profundiza en la tercerización como trabajo colaborativo en la reforma laboral mexicana y la precariedad laboral en España, proporcionando un análisis detallado. Nos sumerge en los modelos de protección social, abordando la financiación de si...

Bioactive Compounds from Plants
Useful throughout history for their medical as well as other benefits, plant-derived compounds have gained particular importance recently, due to environmental factors. The isolation and characterization of plant products, the identification of their role in the plant, and ways of synthesizing identical compounds or more potent analogues are covered. Also includes methods of culturing plant tissues and genetic engineering as a means of increasing the yield of desired substances from plants. Special emphasis is placed on plants previously unknown to Western scientists.
The Annihilation of Nature
"This book shows us the face of Earth’s sixth great mass extinction, revealing that this century is a time of darkness for the world’s birds and mammals. In The Annihilation of Nature, three of today’s most distinguished conservationists tell the stories of the birds and mammals we have lost and those that are now on the road to extinction. These tragic tales, coupled with eighty-three color photographs from the world’s leading nature photographers, display the beauty and biodiversity that humans are squandering."--Book jacket.
A review of evidence on gender equality, women’s empowerment, and food systems
Achieving gender equality and women’s empowerment in food systems can result in greater food security and better nutrition, and in more just, resilient, and sustainable food systems for all. This paper uses a scoping review to assess the current evidence on pathways between gender equality, women’s empowerment, and food systems. The paper uses an adaptation of the food systems framework to organize the evidence and identify where evidence is strong, and where gaps remain. Results show strong evidence on women’s differing access to resources, shaped and reinforced by contextual social gender norms, and on links between women’s empowerment and maternal education and important outcomes,...
The Relative Volatility of Commodity Prices
This paper studies the volatility of commodity prices on the basis of a large dataset of monthly prices observed in international trade data from the United States over the period 2002 to 2011. The conventional wisdom in academia and policy circles is that primary commodity prices are more volatile than those of manufactured products, even though most of the existing evidence does not actually attempt to measure the volatility of prices of individual goods or commodities. Rather the literature tends to focus on trends in the evolution and volatility of ratios of price indexes composed of multiple commodities and products. This approach can be misleading. Indeed, the evidence presented in this paper suggests that on average prices of individual primary commodities may be less volatile than those of individual manufactured goods.
Golden Kingdoms
This volume accompanies a major international loan exhibition featuring more than three hundred works of art, many rarely or never before seen in the United States. It traces the development of gold working and other luxury arts in the Americas from antiquity until the arrival of Europeans in the early sixteenth century. Presenting spectacular works from recent excavations in Peru, Colombia, Panama, Costa Rica, Guatemala, and Mexico, this exhibition focuses on specific places and times—crucibles of innovation—where artistic exchange, rivalry, and creativity led to the production of some of the greatest works of art known from the ancient Americas. The book and exhibition explore not only...
The Role of Productivity, Transportation Costs, and Barriers to Intersectoral Mobility in Structural Transformation
The process of economic development is characterized by substantial reallocations of resources across sectors. In this paper, we construct a multi-sector model in which there are barriers to the movement of labor from low-productivity traditional agriculture to modern sectors. With the barrier in place, we show that improvements in productivity in modern sectors (including agriculture) or reductions in transportation costs may lead to a rise in agricultural employment and through terms-oftrade effects may harm subsistence farmers if the traditional subsistence sector is larger than a critical level. This suggests that policy advice based on the earlier literature needs to be revised. Reducing barriers to mobility (through reductions in the cost of skill acquisition and institutional changes) and improving the productivity of subsistence farmers needs to precede policies designed to increase the productivity of modern sectors or decrease transportation costs.
Handbook of Relativistic Quantum Chemistry
This handbook covers new methodological developments and applications of relativistic quantum chemistry. It also pays attention to the foundation of relativistic quantum mechanics and addresses a number of fundamental issues that have not been covered by any book. For instance, what is the appropriate relativistic many-electron Hamiltonian? How to do relativistic explicit/local correlation? How to formulate relativistic properties? How to combine double-group and time-reversal symmetries? How to do QED calculations for molecules? Just to name a few. This book aims to establish the big picture of relativistic molecular quantum mechanics, ranging from pedagogic introduction for uninitiated rea...
