毁灭资本主义的10大泡沫

中国证券期货 2012年第8期15卷 48-50页

作者： paul b. farrell

2005年年中，距华尔街爆发信贷危机还有三年的时候，《经济学人》（Economjst）杂志就提出了“史上最大泡沫”的警告。当时距2000年互联网泡沫破裂才过去五年，全球房价已经史无前例地上涨了75％。房地产行业即将重蹈互联网行业的覆辙。

The marine losses during the Permo-Triassic mass extinction were the worst ever experienced. All groups were b.dly affected, especially amongst the b.nthos(e.g. b.achiopods, corals, b.yozoans, foraminifers,ostracods). Planktonic populations underwent a fundamental change with eukaryotic algae b.ing replaced b. nitrogen-fixing b.cteria, green-sulphur b.cteria, sulphate-reducing b.cteria and prasinophytes. Detailed studies of b.undary sections, especially those in South China, have resolved the crisis to a ～55 kyr interval straddling the Permo-Triassic b.undary. Many of the losses occur at the b.ginning and end of this interval painting a picture of a two-phase extinction. Improved knowledge of the extinction has b.en supported b. numerous geochemical studies that allow diverse proposed extinction mechanisms to b. studied. A transition from oxygenated to anoxic-euxinic conditions is seen in most sections glob.lly, although the intensity and timing shows regional variab.lity. Decreased ocean ventilation coincides with rapidly rising temperatures and many extinction scenarios attrib.te the losses to b.th anoxia and high *** kill mechanisms include ocean acidification for which there is conflicting support from geochemical proxies and, even less likely, siltation(b.rial under a massive influx of terrigenous sediment) which lacks sub.tantive sedimentological evidence. The ultimate driver of the catastrophic changes at the end of the Permian was likely Sib.rian Trap eruptions and their associated carb.n dioxide emissions with consequences such as warming, ocean stagnation and acidification. Volcanic winter episodes stemming from Sib.rian volcanism have also b.en linked to the crisis, b.t the short-term nature of these episodes(b.real latitudes

Journal of b.havioral and b.ain Science 2024年第2期14卷 47-63页

Patients and physicians understand the importance of self-care following spinal cord injury (SCI), yet many individuals with SCI do not adhere to recommended self-care activities despite logistical supports. Neurob.havioral determinants of SCI self-care b.havior, such as impulsivity, are not widely studied, yet understanding them could inform efforts to improve SCI self-care. We explored associations b.tween impulsivity and self-care in an ob.ervational study of 35 US adults age 18 - 50 who had traumatic SCI with paraplegia at least six months b.fore assessment. The primary outcome measure was self-reported self-care. In LASSO regression models that included all neurob.havioral measures and demographics as predictors of self-care, dispositional measures of greater impulsivity (negative urgency, lack of premeditation, lack of perseverance), and reduced mindfulness were associated with reduced self-care. Outcome (magnitude) sensitivity, a latent decision-making parameter derived from computationally modeling successive choices in a gamb.ing task, was also associated with self-care b.havior. These results are preliminary;more research is needed to demonstrate the utility of these findings in clinical settings. Information ab.ut associations b.tween impulsivity and poor self-care in people with SCI could guide the development of interventions to improve SCI self-care and help patients with elevated risks related to self-care and secondary health conditions.

The Raohe area of Heilongjiang Province， Northeast China b.longs to the Nadanhada Terrane， which was in low latitudes of Panthalassa during the Triassic. The composition of the Late Triassic conodont fauna， derived from limestone lenses interpreted to b. formed on seamounts， provides important new information on the pelagic b.ota in this ocean. New conodont samples collected from sections at Minzhu， Minnan and Chigangb.i b.long to three Norian conodont zones. In ascending order， they are: Mockina postera Zone， Mockina b.dentata Zone and Parvigondolella andrusovi Zone. The Norian conodont fauna in the Raohe area has distinct attrib.tes: there are a lot of cosmopolitan species (e.g. Mockina postera， Mockina b.dentata， Parvigondolella andrusovi) which enab.e good glob.l correlation; endemic conodont species are also present， (e.g. Mockina sakurae， Mockina shamiseni， Norigondolella nadanhadaensis) indicating that Panthalassa Ocean conodont populations also contains unique taxa; and some conodonts b.long to taxa with much shorter ranges in surrounding epeiric seas (e.g. Carnepigondolella pseudoechinata， Neocavitella cavitata and Epigondolella vialovi). The presence of the latter “relicts” indicates that the seamounts were persistently suitab.e hab.tats for many millions of years in the Late Triassic.
