Effectively Engaging with a Dragon: Examining the Nature and Impact of the Most Recent Decade of Sino-African Multilateral Relations

The goal of my research is to examine in detail the impact of the increase in Sino-African trade on African political and economic development. The primary focus will be on two central aspects of Sino-African trade: the effects of China’s natural resource binge coupled with the flood of textiles and other manufactured goods from China to Africa. This thesis will determine the precise nature and extent ofSino-African trade in these sectors and will attempt to determine whether or not Chinese trade is having a net positive impact on long-term African economic development. I will investigate this issue from numerous perspectives using English, Chinese, and African sources.

Structure and thermodynamics of H3O+(H2O)8 clusters: A combined molecular dynamics and quantum mechanics approach

We have studied the structure and stability of (H3O+)(H2O)8 clusters using a combination of molecular dynamics sampling and high-level ab initio calculations. 20 distinct oxygen frameworks are found within 2 kcal/mol of the electronic or standard Gibbs free energy minimum. The impact of quantum zero-point vibrational corrections on the relative stability of these isomers is quite significant. The box-like isomers are favored in terms of electronic energy, but with the inclusion of zero-point vibrational corrections and entropic effects tree-like isomers are favored at higher temperatures. Under conditions from 0 to 298.15 K, the global minimum is predicted to be a tree-like structure with one dangling singly coordinated water molecule. Above 298.15 K, higher entropy tree-like isomers with two or more singly coordinated water molecules are favored. These assignments are generally consistent with experimental IR spectra of (H3O+)(H2O)8 obtained at 150 K.

Compulsive-Like Behaviors of Typical Development: A Question of Their Nature and Continuity with Obsessive-Compulsive Disorder

OBJECTIVE: To investigate compulsive-like behaviors (CLB) of typical development: how they relate to the obsessions and compulsions of obsessive-compulsive disorder (OCD); and the implication of their lingering past 6 years of age (i.e., past their normative, 2-to-5 year, drop). CONCLUSIONS: Findings suggest that normative CLB exist on a continuum (with regard to both symptomatology and functional difficulties) with clinical obsessions and compulsions. With normative repetitive behaviors predicting behavioral perseveration among typically developing individuals aged 6 to 17 years, the present study also suggests that, even in a non-clinical sample, some levels of CLB are maladaptive in middle childhood through adolescence. While studies to date have evaded investigation of high and low CLB in relation to OCD, this latter finding contributes to the growing emphasis upon continuity between typical and atypical development.
