Chinese Foreign Direct Investment in the Caribbean

The purpose of this study is to examine the influence of trade patterns and market size in a short time period, in order to identify indicators of the objectives for Chinese foreign direct investment (FDI) into the Caribbean region. Key questions assessed are: What makes the Caribbean particularly advantageous for Chinese investors and how does the host country benefit? Is a higher level of trade, or wealthier markets, associated with higher Chinese FDI? Is China pursuing some foreign policy objectives with FDI in the region? I hypothesize that Chinese FDI is associated with trade, natural resources, or certain foreign policy objectives in the Caribbean region. My results found that Chinese imports and Chinese exports are positively correlated, and those Caribbean countries that rely upon imports from China are more likely to receive more FDI, where FDI takes the form of investments in infrastructure, agricultural and natural materials. Overall, Caribbean nations use FDI to stimulate and develop their local economies and infrastructure, but at the expense of the exploitation of their raw materials and natural resources, or by entering into binding foreign policy commitments and contracts that are not necessarily politically or economically beneficial to them in the long run

Foundations of Translational Ecology

Ecologists who specialize in translational ecology (TE) seek to link ecological knowledge to decision making by integrating ecological science with the full complement of social dimensions that underlie today\u27s complex environmental issues. TE is motivated by a search for outcomes that directly serve the needs of natural resource managers and decision makers. This objective distinguishes it from both basic and applied ecological research and, as a practice, it deliberately extends research beyond theory or opportunistic applications. TE is uniquely positioned to address complex issues through interdisciplinary team approaches and integrated scientist–practitioner partnerships. The creativity and context-specific knowledge of resource managers, practitioners, and decision makers inform and enrich the scientific process and help shape use-driven, actionable science. Moreover, addressing research questions that arise from on-the-ground management issues – as opposed to the top-down or expert-oriented perspectives of traditional science – can foster the high levels of trust and commitment that are critical for long-term, sustained engagement between partners

The James Webb Space Telescope Mission

Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized space telescope with an aperture of at least $4m$. With the support of their governments in the US, Europe, and Canada, 20,000 people realized that vision as the $6.5m$ James Webb Space Telescope. A generation of astronomers will celebrate their accomplishments for the life of the mission, potentially as long as 20 years, and beyond. This report and the scientific discoveries that follow are extended thank-you notes to the 20,000 team members. The telescope is working perfectly, with much better image quality than expected. In this and accompanying papers, we give a brief history, describe the observatory, outline its objectives and current observing program, and discuss the inventions and people who made it possible. We cite detailed reports on the design and the measured performance on orbit.Comment: Accepted by PASP for the special issue on The James Webb Space Telescope Overview, 29 pages, 4 figure

Origin of impurities formed in the polyurethane production chain. 1: conditions for chlorine transfer from an aryl isocyanide dichloride byproduct

Phenyl and 4-methylphenyl isocyanide dichlorides are models for byproduct that may be formed in the later stages of certain polyurethane production chains. Photochemical electron paramagnetic resonance (EPR) studies (λ > 310 nm), using the spin trap, N-tert-butyl-α-phenylnitrone, confirm a previously made suggestion that ArN═CCl2 can behave as a chlorine radical source. EPR spectra recorded during and after irradiation and supported by simulations evolve over time and indicate formation of the short-lived spin trap–Cl• adduct and a longer lived benzoyl-N-tert-butylnitroxide radical. Photolysis of C6H5N═CCl2, either alone or mixed with methylene diaryl isocyanate species, in o-C6H4Cl2, a polyurethane process solvent, led to the formation of mixtures containing dichloro- and trichlorobiphenyl isomers
