The legume pod borer, Maruca vitrata (Lepidoptera: Crambidae; syn. M. testulalis), is a serious pantropical insect pest of grain legumes. Comparative studies of M. vitrata female sex pheromone components in two different geographic populations in China, Wuhan and Huazhou, confirmed that (E,E)-10,12-hexadecadienal (E10,E12-16:Ald) and (E)-10-hexadecenal (E10-16:Ald) were present in variable rati...

The E2A gene products, E12 and E47, are critical regulators of B cell development. However, it remains elusive whether E12 and E47 have overlapping and/or distinct functions during B lymphopoiesis. We have generated mice deficient for either E12 or E47 and examined their roles in B cell maturation. We show that E47 is essential for developmental progression at the prepro-B cell stage, whereas E...

The HT29MTXE12 (E12) cell line harbors an adherent mucus layer, providing a novel technique to model mucosal infection in vitro. In this study, we have characterized the interaction of Campylobacter jejuni with the E12 cell line and exploited its unique mucus layer to examine the potential efficacy of probiotic treatment to attenuate C. jejuni virulence properties. C. jejuni 81-176 colonized an...

The present paper thoroughly explores second-best efficient allocations in an adverse selection insurance economy. We start from a natural extension of the classical model, assuming less than perfect risk perceptions. We propose first and second welfare theorems, by means of which we describe efficiencyenhancing policies. Notions of weak and strong adverse selection are promising for interpreti...

In an open multi-country economy, the safe assets supply shapes pattern of international capital flows. A higher productivity growth rate raises net inflows for economies with abundant assets, but reduces scarce assets. The cross-section analysis on a sample 170 over 1980–2013 confirms theory. evidence is robust instrument-variable (IV) method. JEL Classifications: F15, F36, F43

there are various views about deceision making for the model of growing crops in risky conditions such as: motad model, inome - variance, grade2 planning, inseparable linear planning, and limited extreme risk model, focus-loss model, and target- motad . in this study, target - motad model has been used as the optimum pattern of growing crops in arsanjan. the results have been compared with thos...

Indonesia, like many other countries in South East Asia, has actively promoted the automotive industry. The governmental interventions have ranged from tariffs and nontariff barriers to various local content programs. As a result, imports of ready made cars and motorcycles have been expensive, which led to an inflow of foreign producers. This paper examines the productivity performance in the I...

The impacts of choice in public services are controversial. We exploit a reform in the English National Health Service to assess the impact of relaxing constraints on patient choice. We estimate a demand model to evaluate whether increased choice increased demand elasticity faced by hospitals with regard to clinical quality and waiting time for an important surgical procedure. We find substanti...
