Revealed preference is the dominant approach for inferring preferences, but it relies on discrete, stochastic choices. The choice process also produces response times (RTs) which are continuous and can often be observed in the absence of informative choice outcomes. Moreover, there is a consistent relationship between RTs and strength-of-preference, namely that people make slower decisions as t...
The Economics of Risky Health Behaviors Risky health behaviors such as smoking, drinking alcohol, drug use, unprotected sex, and poor diets and sedentary lifestyles (leading to obesity) are a major source of preventable deaths. This chapter overviews the theoretical frameworks for, and empirical evidence on, the economics of risky health behaviors. It describes traditional economic approaches e...
Does poverty lead to stress? Despite several studies showing correlations between socioeconomic status and levels of the stress hormone cortisol, it remains unknown whether this relationship is causal. We used random weather shocks in Kenya to address this question. Our identification strategy exploits the fact that rainfall is an important input for farmers, but not for non-farmers such as urb...
The successful establishment of a species in a given habitat depends on the ability of each of its developing stages to adapt to the environment. In order to understand this process we have studied the adaptation of a euryhaline fish, the sea-bass Dicentrarchus labrax, to various salinities during its ontogeny. The expression and localization of Aquaporin 1a (AQP1a) mRNA and protein were determ...
Increasing antibacterial resistance and pathogenicity in the environment is of growing concern due to its potential human risk. In the present study, 236 Escherichia coli isolates were collected from Wenyu River in China on drugless (48 isolates) and quinolone-containing plates (189 isolates). Their minimum inhibitory concentrations (MICs) were determined ranging from 0.125 μg mL(-1) to 128 μg ...
قتصاد مبتنی بر عصبشناسی از تعامل علوم عصبشناسی، اقتصاد و روان‌شناسی به وجود آمده و نویدبخش رویکردی جدید در تحلیلهای اقتصادی به ویژه درک رفتار انسان به عنوان فردی انتخابگر - که موضوعی بنیادین در علم اقتصاد میباشد- است. این مقاله، مزیتهای اقتصاد مبتنی بر عصبشناسی را به تصویر کشیده و با تمرکز بر روششناسی علم اقتصاد و توانایی این شاخه در تئوریپردازی اقتصادی، در پی دفاع از این شاخه برآمده ...

To understand the genetic basis of high drug resistance in Shigella, 95 clinical isolates of Shigella spp. (2001-2010) were obtained from the Infectious Diseases Hospital, Kolkata, India. Ninety-three isolates were resistant to three or more antibiotics. Resistance to nalidixic acid, trimethoprim, streptomycin, and co-trimoxazole was most common in this population. Dendrogram analysis showed th...
