The recently isolated broad-spectrum antiparasitic apicidin (1) is one of the few naturally occurring cyclic tetrapeptides (CTP). Depending on the solvent, the backbone of 1 exhibits two gamma-turns (in CH(2)Cl(2)) or a beta-turn (in DMSO), differing solely in the rotation of the plane of one of the amide bonds. In the X-ray crystal structure, the peptidic C==Os and NHs are on opposite sides of the backbone plane, giving rise to infinite stacks of cyclotetrapeptides connected by three intermolecular hydrogen bonds between the backbones. Conformational searches (Amber force field) on a truncated model system of 1 confirm all three backbone conformations to be low-energy states. The previously synthesized analogs of 1 containing a reduced amide bond exhibit the same backbone conformation as 1 in DMSO, which is confirmed further by the X-ray crystal structure of a model system of the desoxy analogs of 1. This similarity helps in explaining why the desoxy analogs retain some of the antiprotozoal activities of apicidin. The backbone-reduction approach designed to facilitate the cyclization step of the acyclic precursors of the CTPs seems to retain the conformational preferences of the parent peptide backbone.
While scholars of contemporary philanthropy have observed a concerted interest in the promotion of 'self-help,' little has been said about the political history of this investment and its significance in determining both domestic and international development priorities. We locate this modern conceptualisation of self-help in early twentieth-century philanthropic practice that sought to 'gift' to individuals and communities the precious habit of self-reliance and social autonomy. The Rockefeller Foundation promoted rural development projects that deliberately sought to 'emancipate' the tradition-bound peasant, transforming him or her into a productive, enterprising subject. We begin by documenting their early agricultural extension work, which attempted to spark agrarian change in the US South through the inculcation of modern habits and aspirations among farmers and their families. These agrarian schemes illustrate the newfound faith that 'rural up-lift' could only be sustained if farming communities were trained to 'help themselves' by investing physically and psychologically in the process of modernisation. We then locate subsequent attempts to incentivise and accelerate international agricultural development within the broader geopolitical imperatives of the Green Revolution and the Cold War. While US technical assistance undoubtedly sought to prevent political upheaval in the Third World, we argue that Rockefeller-led modernisation projects, based on insights gleaned from behavioural economics, championed a model of human capital -and the idea of 'revolution within' -in order to contain the threat of 'revolution without'. Approaching agricultural development through this problematisation of the farmer reveals the 'long history' of the Green Revolution -unfolding from the domestic to the international and from the late nineteenth century to the present -as well as the continuing role of philanthropy in forging a new global order.
Dear PhilipPlease find our freshly revised paper! It may help to briefly outline the main changes we have made to the MS:1. We have removed the concluding paragraph that summarised the paper's findings and which you felt (and we agree) was largely superfluous. 2. We have added a small amount of text to the abstract, the 'cultivating global citizens' section and the conclusion -basically the sections where you felt additions might be happily made -to ensure that the theme of internationalism is explicit. 3. We have removed several citations from the bibliography -sources that were not directly cited in the text -in an effort to reduce the word count further (against that we now include a reference to Mono Domosh's paper). 4. As requested we now indicate roughly where the images should be placed and provide appropriate captions for each one.We hope you approve the revisions we've made, but do please get in touch if you have any further concerns.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
