Why doesn't Capitalism flow to Poor Countries?
Abstract We find anecdotal evidence suggesting that governments in poor countries have a more left wing rhetoric than those in OECD countries. Thus, it appears that capitalist rhetoric doesn't flow to poor countries. A possible explanation is that corruption, which is more widespread in poor countries, reduces more the electoral appeal of capitalism than that of socialism. The empirical pattern of beliefs within countries is consistent with this explanation: people who perceive corruption to be high in their country are also more likely to lean left ideologically (and to declare support for a more intrusive government in economic matters). Finally, we present a model explaining the corruption-left connection. It exploits the fact that an act of corruption is more revealing about the fairness type of a rich capitalist than of a poor bureaucrat. After observing corruption, voters who care about fairness react by increasing taxes and moving left. There is a negative ideological externality since the existence of corrupt entrepreneurs hurts good entrepreneurs by reducing the electoral appeal of capitalism. JEL: P16, K42, E62
Isolation and Characterization of Live Yeast Cells from Ancient Vessels as a Tool in Bio-Archaeology
So far, most of the study of ancient organisms has been based mainly on the analysis of ancient DNA. Here we show that it is possible to isolate and study microorganisms—yeast in this case—from ancient pottery vessels used for fermentation. We demonstrate that it is highly likely that these cells are descendants of the original yeast strains that participated in the fermentation process and were absorbed into the clay matrix of the pottery vessels. Moreover, we characterized the isolated yeast strains, their genomes, and the beer they produced. These results open new and exciting avenues in the study of domesticated microorganisms and contribute significantly to the fields of bio- and experimental archaeology that aim to reconstruct ancient artifacts and products.Ancient fermented food has been studied based on recipes, residue analysis, and ancient-DNA techniques and reconstructed using modern domesticated yeast. Here, we present a novel approach based on our hypothesis that enriched yeast populations in fermented beverages could have become the dominant species in storage vessels and their descendants could be isolated and studied today. We developed a pipeline of yeast isolation from clay vessels and screened for yeast cells in beverage-related and non-beverage-related ancient vessels and sediments from several archaeological sites. We found that yeast cells could be successfully isolated specifically from clay containers of fermented beverages. The findings that genotypically the isolated yeasts are similar to those found in traditional African beverages and phenotypically they grow similar to modern beer-producing yeast strongly suggest that they are descendants of the original fermenting yeast. These results demonstrate that modern microorganisms can serve as a new tool in bio-archaeology research
Validation of a Novel Assay to Distinguish Bacterial and Viral Infections
Reliably distinguishing bacterial from viral infections is often challenging, leading to antibiotic misuse. A novel assay that integrates measurements of blood-borne host-proteins (tumor necrosis factor-related apoptosis-inducing ligand, interferon Îł-induced protein-10, and C-reactive protein [CRP]) was developed to assist in differentiation between bacterial and viral disease
