Reconciling IMF rules and international investment agreements: An innovative derogation for capital controls

In the absence of an international framework governing capital controls, a conflict has developed due to the different approaches towards such controls taken by various international organizations and international investment agreements (IIAs). IIAs should incorporate derogations for countries when treaty obligations conflict with IMF recommendations to impose controls in response to severe economic hardship

协调IMF规定与IIAs：资本控制的一种创新性免责条款

目前，对于资本控制的管理问题还没有形成一个统一的框架。不同的国际组织与国际协定（IIAs）采取不同的做法，由此产生了冲突。当协议责任与IMF应对严重经济困难的建议相冲突时，IIAs应该加入免责条款

\u3ci\u3eDrosophila\u3c/i\u3e Muller F Elements Maintain a Distinct Set of Genomic Properties Over 40 Million Years of Evolution

The Muller F element (4.2 Mb, ~80 protein-coding genes) is an unusual autosome of Drosophila melanogaster; it is mostly heterochromatic with a low recombination rate. To investigate how these properties impact the evolution of repeats and genes, we manually improved the sequence and annotated the genes on the D. erecta, D. mojavensis, and D. grimshawi F elements and euchromatic domains from the Muller D element. We find that F elements have greater transposon density (25–50%) than euchromatic reference regions (3–11%). Among the F elements, D. grimshawi has the lowest transposon density (particularly DINE-1: 2% vs. 11–27%). F element genes have larger coding spans, more coding exons, larger introns, and lower codon bias. Comparison of the Effective Number of Codons with the Codon Adaptation Index shows that, in contrast to the other species, codon bias in D. grimshawi F element genes can be attributed primarily to selection instead of mutational biases, suggesting that density and types of transposons affect the degree of local heterochromatin formation. F element genes have lower estimated DNA melting temperatures than D element genes, potentially facilitating transcription through heterochromatin. Most F element genes (~90%) have remained on that element, but the F element has smaller syntenic blocks than genome averages (3.4–3.6 vs. 8.4–8.8 genes per block), indicating greater rates of inversion despite lower rates of recombination. Overall, the F element has maintained characteristics that are distinct from other autosomes in the Drosophila lineage, illuminating the constraints imposed by a heterochromatic milieu
