This paper contributes to the increasing research on how experts within financial institutions co-produce and organize financial markets, and in particular how equity analysts enact stock markets characterized by high volume and volatility. The 20 equity analysts studied give qualitatively different accounts of what, from an outsider's perspective, appear to be very similar work. The analysts understand investment objects, equity markets, and what constitutes good analytical work in qualitatively different ways. This heterogeneity, or multiplicity, could be one source of the, unexplained by orthodox financial theory, ‘excess’ volatility and ‘excess’ trading volume on financial markets. Therefore, the paper complements accounts within heterodox finance theory and sociology-based studies of financial market activities. 相似文献

INTRODUCTION There is increased need in recent years for strengthening or rehabilitation of existing reinforced concrete structures adversely affected by overloading, construction material deterioration, seismic loads, structural deformation, etc. An effective method for increasing the shear capacity of reinforced concrete columns is the use of externally bonded carbon fiber reinforced plastic (CFRP) systems (ACI, 2002). FRP systems were first applied to reinforced concrete col-umns i… 相似文献

INTRODUCTION Dynamics of carbon and water vapor fluxesexchange between the atmosphere and the ecosystembiosphere, depend on complex and non-liner interplayamong physiological, ecological, biochemical andedaphic factors and meteorological conditions (Jarvis,1995; Leuning et al., 1995). There are many studiesquantifying the fluxes across different time and spacescales as well as assessing the environment con-straints on them by some kinds of biophysical orempirical models whose resul… 相似文献

第一次鸦片战争后,中国传统的外交体制受到冲击,第二次鸦片战争后,总理衙门、南北洋大臣的设置则弱化了清廷传统之对外关系.南北洋大臣所参与的外交活动构成了晚清外交实践的主体,对晚清外交传统观念向近代化的演进转变、及外交体制的近代化有着重要的影响.但晚清国力衰弱、专制政体、不完整的外交策略、传统意识的桎梏和近代外交知识的贫乏... 相似文献

以地方政府为参加主体的流域排污权多方动态交易机制是排污权市场研究的一个空白点。应用特定的模型分析可以看到,在连续的动态交易机制下,给予流域地方政府足够时间和交易频率,排污权价格将会从非均衡价格趋向均衡价格,由此就会实现成本有效的排污权交易市场,从而可以降低流域总削污成本。同时,通过拍卖机制设计,也可以简化排污权多方连续动态交易机制,降低交易成本。 相似文献

Rats fed with hypercholesterolemic diet showed a significant increase in serum total—cholesterol, liver homogenate total-cholesterol,
HDL-cholesterol and changed LDL-cholesterol, and HDL/LDL ratio in comparison to control. Flaxseedchutney (FC) supplemented diet (15%, w/w) was found to be more effective in restoring lipid profile changes in rats fed with cholesterol,
(1.0%). The activities of serum marker enzymes glutamate oxaloacetate transminase (GOT), glutamate pyruvate transaminase (GPT)
and alkaline phosphatase (ALP) were elevated significantly in carbon tetrachloride induced rats. Administration of flaxseedchutney (15%, w/w) resulted in depletion of serum marker enzymes and exhibited recoupment thus showing significant hepatoprotective
effect. It was observed that flaxseedchutney supplemented diet could lower the serum cholesterol and as a potential source of antioxidants it could exert protection against
hepatotoxic damage induced by carbon tetrachloride (CCl4) in rats. 相似文献

Researchers examining carbon dioxide-equivalent emissions (carbon footprint) in sport have focused on sport events and, to a lesser extent, sport teams, but provided only average or aggregate values. The author takes the perspective of active sport participants and considers the heterogeneity of individual sport participation behavior. Using online surveys, adult active sport participants (n = 6537) in 20 different sports with main residence in Germany were asked to report their sport-travel behavior in 2015, including traveling in the context of regular (weekly) activity, sport competitions/tournaments, league games, day trips, and training camps/vacations. Annual carbon footprints were estimated using information about travel distances and transportation means. The results revealed an average annual carbon footprint of 844 kg of carbon dioxide-equivalent emissions, with individual sports producing more emissions than team/racket sports. Participants in nature sports had the highest emission levels. Regression analyses revealed that environmental consciousness significantly reduced carbon footprint in individual sports, but not in team/racket and nature sports, supporting the existence of an environmental value-action gap. Activity years, club membership, weekly exercise hours, performance level, and income were mainly positively associated with annual carbon footprint, while gender was insignificant. The findings have implications for policy makers and managers in sport associations and clubs. 相似文献
