We report some results on the complex-temperature ~CT! singularities of q-state Potts models on the square lattice. We concentrate on the problematic region Re(a),0 ~where a5e) in which CT zeros of the partition function are sensitive to finite lattice artifacts. From analyses of low-temperature series expansions for 3<q<8, we establish the existence, in this region, of complex-conjugate CT sin...

Public authorities often invoke the precautionary principle to ban or postpone the development of innovative projects with uncertain but potentially harmful irreversible impacts on the environment or health. As stated in the Rio declaration, the precautionary principle suggests balancing costs and benefits associated with irreversible decisions while taking account of the perspective to acquire...

In an open economy, can unilateral environmental policies undertaken by a group of committed countries ensure sustainable growth? This paper addresses this question in a dynamic model with directed technical change. There are two countries and two tradeable goods. One of the two goods (the polluting good) is produced with a clean input and a dirty input, which causes a global externality. Innov...

The theoretical and empirical innovation literature stresses the importance of regional factors and location conditions for location choice of firms and their innovation success. Innovation activities are not equally distributed in space because agglomeration effects and specific regional infrastructures may promote innovation activities. Concerning environmentally oriented innovations, the so-...

“This paper is the second by this group of authors to be designated as a Citation Classic. The first deals with the capacitance-voltage method used to investigate metal-oxidesemiconductor (MOS) structures.1 Two other publications have also proved very popular—one discusses the effect of alkali ions, i.e., Na+, on MOS instability,2 and the other presents the general relationship for the thermal ...

Limited data exist on consumer beliefs and practices on the role of omega-3 fatty acid and vitamin D dietary supplements and health. For this reason, theGlobal Health andNutrition Alliance conducted an online survey in 3 countries (n = 3030; United States = 1022,Germany = 1002,UnitedKingdom= 1006) of a convenience sample of adults (aged 18Y66 years) who represented the age, gender, and geograph...

This paper provides new empirical evidence on Environmental Kuznets Curves (EKC) for greenhouse gases (GHGs) and air pollutants at sector level. A panel dataset based on the Italian NAMEA over 1990-2005 is analysed, focusing on both emission efficiency (EKC model) and total emissions (IPAT model). Results show that looking at sector evidence, both decoupling and also eventually re-coupling tren...

Deep sequencing was used to investigate the subchronic effects of 1 ppm aflatoxin B1 (AFB1), a potent hepatocarcinogen, on the male rat liver transcriptome prior to onset of histopathological lesions or tumors. We hypothesized RNA-Seq would reveal more differentially expressed genes (DEG) than microarray analysis, including low copy and novel transcripts related to AFB1's carcinogenic activity ...

In this paper, which forms a chapter in the forthcoming Book “Delivering a Low Carbon Electricity System: Technologies, Economics and Policy”, Grubb and Newbery examine how carbon for electricity generation should be priced. They begin by suggesting that it is not clear what the correct price of carbon is, but that it spans the whole range of economically plausible prices. They then go on to di...
