We have investigated the immunogenicity in rabbits of native-like, soluble, recombinant SOSIP.664 trimers based on the env genes of four isolates of human immunodeficiency virus type 1 (HIV-1); specifically BG505 (clade A), B41 (clade B), CZA97 (clade C) and DU422 (clade C). The various trimers were delivered either simultaneously (as a mixture of clade A + B trimers) or sequentially over a 73-...
استفاده از Agrobacterium rhizogenes جهت ایجاد کشت ریشه‌های موئین، روشی مناسب برای افزایش تولید متابولیت‌های ثانویه به خصوص ترکیبات دارویی به‌روش in vitro در گونه‌های گیاهی مختلف می‌باشد. سیستم‌های ریشه‌موئین دارای رشد بسیار سریع بوده و به‌دلیل داشتن انشعابات و تار‌های کشنده فراوان و همچنین میزان بیشتر سنتز متابولیت‌ها در هر واحد بیوماس (زیست‌توده)، دارای ظرفیت بیوسنتزی مشابه و یا بیشتر از ریشه...

This paper considers some methodological aspects of Joan Robinson’s contribution to post-Keynesian growth theory. Joan Robinson’s criticisms of equilibrium analysis, of the conflation of logical and historical time and of the uses (and misuses) of mathematical formalisation are scathing. But while many of her points are well taken, parts of her argument appear questionable. As a result, her met...
Laboratory experiments have generally supported the theorem that, in classical property rights environments, noncooperative behavior in markets yields efficient social outcomes. Experiments, however, regularly fail to support the game theoretic prediction of noncooperative behavior in small-group strategic interaction and in large-group public good environments. In these two types of experiment...
Authors of experimental, empirical, theoretical and computational studies of two-sided matching markets have recognized the importance of correlated preferences. We develop a general method for the study of the effect of correlation of preferences on the outcomes generated by two-sided matching mechanisms. We then illustrate our method by using it to quantify the effect of correlation of prefer...
This paper proposes a geometric delineation of distributional preference types and a non-parametric approach for their identification in a two-person context. It starts with a small set of assumptions on preferences and shows that this set (i) naturally results in a taxonomy of distributional archetypes that nests all empirically relevant types considered in previous work in economics and socia...
Transactions at non-equilibrium prices are “false trades”. Under standard assumptions, markets without false trading produce Pareto-efficient outputs. This paper demonstrates graphically the complications created when false trades occur, showing that quantities produced deviate from Pareto-efficient quantities except under unique conditions. In a general equilibrium framework, this spills over ...
Economic theory has evolved without paying proper attention to behavioral approaches, especially to social, economic, and cognitive psychology. This has recently changed by including behavioral economics courses in many doctoral study programs. Although this new development is most welcome, the typical topics of the behavioral economics courses are not truly behavioral. More specifically, we qu...
