Traditionally, integration has been studied at the country level. With increasing economic integration, industrial reorganization, and blurring of national boundaries (e.g., EU), it is important to investigate global integration at the industry level. We argue that country-level integration (segmentation) does not preclude industry-level segmentation (integration). Indeed, our results suggest t...

The aim of this paper is to expand the methodological spectrum of socially responsible investing by introducing stochastic sustainability returns into safety first models for portfolio choice. We provide a foundation of the notion of sustainability in portfolio theory and establish a general model for generalized safety first portfolio management with probabilistic constraints and three special...

Using Web-of-Science data, portfolio analysis in terms of journal coverage can be projected on a base map for units of analysis such as countries, cities, universities, and firms. The units of analysis under study can be compared statistically across the 10,000+ journals. The interdisciplinarity of the portfolios is measured using Rao-Stirling diversity or Zhang et al.’s (in press) improved mea...

[1] The Mesozoic, perhaps the longest period of warmth during the Phanerozoic Earth history, has been repeatedly affected by short‐lived cold interludes lasting about one million years. While the origin of these cold snaps has been classically attributed to a temporary atmospheric CO2 drawdown, quantified mechanisms explaining these instabilities of the carbon cycle are still lacking. Based on ...

In the contemporary literature on recorded performance, the standard view is that today there is less diversity among interpretations of concert-hall music than in the first decades of the twentieth century.1 When explaining this lack of diversity, commentators generally point to specific record industry practices and the way performers use sound recordings. It is often claimed that with the ad...

As part of the model validation and development activities of a European research initiative in the area of passive solar architecture, a validation/calibration methodology has been developed which emphasises the use of empirical data in the model proving process and, if necessary, model calibration before use. This procedure has been applied to the ESP-r system in order that it might be used t...

We extend a Kalman filter model for count data to reflect observations irregularly spaced in time. The model is applied to estimate risk of rare events; bycatch of endangered leatherback turtles in a swordfish fishery off Oregon and California. Incidental takes of turtles are modeled as a Poisson process. The results suggest that take risk is better estimated by regarding the entire history of ...

Transportation services are central to movement of goods and people in modern economies. Their provision embodies many tradeoffs between: economic benefits, health effects, social and environmental impacts. Policies aimed at achieving deep greenhouse gas emission reductions from the transportation sector will invariably impact the balance of these benefits and dis-benefits of transportation. Th...

in order to compare morphophysiological traits between new and old cultivars of barley (hordeum vulgare l.) a greenhouse experiment was conducted in greenhouse condition in faculty of agriculture, ferdowsi university of mashhad in spring and summer 2011.the type of experiment was a completely randomized design with eight treatments (nosrat , youssof , fagr30 , nick) and four old cultivars inclu...
