金融业的发展对经济增长起着重要作用,提高了金融业的知名度和数量。虽然发展-金融关系的增长在学术研究中得到了广泛关注,但还需重点研究以下领域中存在的研究空白点:例如金融部门在增长路径中的实际互动、脉冲响应效应、金融波动冲击联系,以及法律制度中的信息不对称问题。了解这些相互影响对于完善金融服务体系和检验审慎的宏观经济战略非常重要。以非洲为例,本文利用成熟的计量经济学技术分别研究了其中的经验临界差距。这项研究的重点是金融发展和经济增长对金融绩效的影响,同时是一项关于非洲金融行业发展的实证研究。本研究调查的目标如下:(1)探索当金融和实体部门的相对增长速度不均衡时金融发展与经济增长联系的影响,旨在探索金融发展(FD)和经济增长(EG)关系在非洲的影响。(2)确定金融机构的波动性和银行绩效,以及监管如何通过影响其信息不对称来产生波动性。关键在于,超出了最初设定条件对金融行业发展和经济不稳定的影响。(3)考察银行政策调控对波动性成分的影响,以及金融通过哪些渠道影响经济不稳定。由于金融发展通过其各个组成部分影响波动性,本研究将波动性分解为商业周期和长期组成部分,以检验金融部门发展与波动性之间的联系。此外,论文还确定了管理和政策决策如何通过与实际和货币冲击的相互作用影响波动因素。为了进行实证分析,本研究首先进行了初步检验,包括单位根检验,多重共线性检验,面板协整检验,格兰杰因果检验等。在初步检验的基础上,本研究采用了Pvar模型、面板分位数固定效应回归等计量经济学方法。由于正态性检验表明数据通常不是分布式的,偏差是由条件均值模型(例如OLS估计)引起的。在这种情况下,PQ估计了不同分布五分位数上的结果,并提供异类响应。面板分位数、稳定性检验和均数组估计以其对异常值的稳健性和捕捉OLS和其他经典计量经济学方法难以处理的所有重要关系的能力而闻名。我们使用了Machado和Santos Silva最新的PQ系统(MM-QR)。MM-QR用于通过矩条件估计结果(Machado和Santos Silva,2019),这些矩条件不假定矩函数的存在或进行分布假设,这与以前的分位数回归方法不同。本研究进行了一系列诊断测试以检查模型的稳健性,结果表明,除了异方差问题外,我们没有偏离重要的标准假设。为了纠正可能导致无效估计的异方差性,本研究利用PVAR模型,通过引入固定效应来增加数据的一致性和一致性测量,从而解决了数据中横截面的动态异质性,尤其是在EG和财务变量较大的情况下在某些非洲国家之间存在异质性。其次,PVAR-GMM面板为内生和外生冲击提供了一个模型,对于开放经济体来说,该模型可以说是宏观经济动态的最重要来源。最后,PVAR模型对特定的增长理论持中立态度,这使得该模型相比于某些宏观经济动力学原理实施的PVAR通用公式,更多地依赖于一系列现行活动,如果不被接受则会扭曲。在本文中,我们研究了广义的新古典增长模型,该模型探讨了金融发展与经济增长的内生机制。定量研究表明,卓越的金融发展是在经济增长过程中不断进步的,以满足实体经济的各种需求。从1980年到2017年,我们利用非洲西部、南部、北部、中部和东部34个区域国家的面板数据,利用面板分位数回归和PVAR技术,调查了金融发展是否对经济增长有重要影响。实证结果表明,金融发展对经济增长具有显著的影响,但除对西部地区进行稳定性诊断检验外,金融发展对区域经济增长的影响存在差异,拟合结果表明,金融发展对区域经济增长的影响呈不均衡增长。这些发现证实了金融发展-经济增长在经济增长的不同阶段是不断发展的。此外,通过非洲的西部、中部、东部、北部和南部地区,银行业发展对经济增长具有更大的横向影响。(1)虽然有强有弱,但非洲的业务发展与经济发展之间存在格兰杰因果关系;对于典型的欠发达经济体而言,分配给股票市场的资金的持续流通似乎较少,导致经济增长的放缓,使得经济增长产生的可投资资金较少在股票市场拓展市场。(2)银行体系的增长和通货膨胀之间存在明显的格兰杰因果关系,对于收入较低的经济体,银行系统提供的资金似乎部分流入了通货膨胀,而不是经济增长,导致了高通胀和微弱的经济增长。同样,本研究量化了发达国家和发展中国家金融机构的新兴特征及其鲜明特征。本研究调查了非洲发展中经济体银行绩效的决定因素,如非洲金融部门的银行绩效指标(金融盈利能力,利率,通货膨胀率,银行存款,银行信贷和银行流动性),并通过概念和假设来推动研究。结果表明,在面板向量自回归(PVAR)的敏感性测试中,通过方差分解(VD)分析,银行信贷和银行存款报告可改善银行绩效,并在第10期对所有非洲经济体进行了解释。但是,动态面板分位数结果表明,金融机构在不同的分位数上具有不同的效应。本研究还为发展中市场的金融机构提供了必要的政策启示。此外,主要的创新体现在各种计量经济学方法的实施上

以最近的金融危机为背景,本文研究了不同金融结构下银行风险因子对系统性风险的影响,对金融体系系统性风险与金融结构的相关文献进行了补充。本文使用结构活动性指数作为金融结构的主要衡量指标,基于28个国家从2007年至2009年的面板数据与固定效应模型进行研究发现,银行风险因子对金融体系系统性风险的影响取决于金融体系的结构:金融结构越偏向市场,银行规模对金融体系系统性风险的贡献越小;反之,金融结构越偏向银行,银行规模对金融体系系统性风险的影响越大。此外,在银行偏向型的金融结构中,银行资本量与金融体系系统性风险负相关;但在市场偏向型的金融结构中,银行资本量与金融体系系统性风险正相关。使用结构规模指数进行稳健性检验,前述结论仍然成立。本文的研究启示在于,当金融监管层制定风险管理政策时,应考虑到不同金融结构下银行风险因子对金融体系系统性风险的异质性影响。

The phytohormone abscisic acid (ABA) modulates the expression of many genes important to plant growth and development and to stress adaptation. In this study, we found that an APETELA2/Ethylene Responsive Binding Protein (AP2/EREBP) type transcription factor, AtERF7, plays an important role in ABA responses. AtERF7 interacts with the protein kinase PKS3, which has been shown to be a global regulator of ABA responses. AtERF7 binds to the GCC box and acts as a repressor of gene transcription. AtERF7 interacts with the Arabidopsis homolog of human global co-repressor of transcription, AtSin3, which in turn may interact with HDA19, a histone deacetylase. The transcriptional repression activity of AtERF7 is enhanced by HDA19 and AtSin3. Arabidopsis plants overexpressing AtERF7 show reduced sensitivity of guard cells to ABA and increased transpirational water loss. In contrast, AtERF7 and AtSin3 RNA interference lines show increased sensitivity to ABA during germination. Together, our results suggest that AtERF7 plays an important role in ABA responses and it may be part of a transcriptional repressor complex and be regulated by PKS3.

Using Marker Assisted Selection to Hasten Screening of Cassava Cultivars Developed through Introgression of Cassava Mosaic Disease （CMD） Resistance into Cassava Landraces in Ghana

引用

Journal of Agricultural Science and Technology(B) 2012年第1期2卷 74-80页

Cassava mosaic disease （CMD）, the most important disease of cassava （Manihot esculenta Crantz） is a potential threat to Africa＇s cassava production. The disease is embedded in most landraces resulting in low yields. Host plant resistance has been found to be the best control strategy. A breeding programme using genetic hybridisation and Marker Assisted Selection was initiated in 2007 to improve the resistance levels of farmer-preferred landraces and reduce the long breeding cycle for developing improved cassava varieties. Thirty farmer-preferred landraces were selected and crossed with a high yielding and mosaic resistant cultivar （TMEI l） from International Institute of Tropical Agriculture （IITA）. The resultant progenies found to have a reasonable level of resistance （score, 1-3） to the CMD were AW 18, 273 Nyamebekyere, NK 43, AW 3, NK 26, K 25, Dabodabo, Ahwengyankwa, 674 Debor, Degarti, Agric Bankye, and NK 57. These resultant progenies were backcrossed to the resistant cultivar. The backcross one （BC l） progenies totaling 224 were screened with molecular markers that are associated to the CMD 2 gene. De-oxyribonucleic Acid （DNA） was extracted from leaves of the 224 BC1 progenies and 13 parents. Two Simple Sequence Repeats （SSR） markers （SSY28 and NSl58） and one Sequenced Characterized Amplified Region （SCAR） marker RME1, were used to screen and select for the resistant BC l progenies. Marker Assisted Selection （MAS） revealed that 82% of the genotypes had at least a marker allele for the CMD2 gene, indicating resistance. The study further revealed that by using MAS, the breeding cycle of cassava in the generation of varieties could be reduced from 8 years to 2 years. The resistant genotypes identified will be evaluated for yield and starch cooking quality in future breeding work.

AIM: To provide consensus statements on the use of per-oral cholangiopancreatoscopy(POCPS).METHODS: A workgroup of experts in endoscopic retrograde cholangiopancreatography(ERCP), endosonography, and POCPS generated consensus statements summarizing the utility of POCPS in pancreaticobiliary disease. Recommendation grades used validated evidence ratings of publications from an extensive literature ***: Six consensus statements were generated:(1) POCPS is now an important additional tool during ERCP;(2) in patients with indeterminate biliary strictures, POCS and POCS-guided targeted biopsy are useful for establishing a definitive diagnosis;(3) POCS and POCS-guided lithotripsy are recommended for treatment of difficult common bile duct stones when standard techniques fail;(4) in patients with main duct intraductal papillary mucinous neoplasms(IPMN) POPS may be used to assess extent of tumor to assist surgicalresection;(5) in difficult pancreatic ductal stones,POPS-guided lithotripsy may be useful in fragmentation and extraction of stones; and(6) additional indications for POCPS include selective guidewire placement,unexplained hemobilia, assessing intraductal biliary ablation therapy, and extracting migrated stents. CONCLUSION: POCPS is important in association with ERCP, particularly for diagnosis of indeterminate biliary strictures and for intra-ductal lithotripsy when other techniques failed, and may be useful for preoperative assessment of extent of main duct IPMN, for extraction of difficult pancreatic stones, and for unusua indications involving selective guidewire placement,assessing unexplained hemobilia or intraductal biliary ablation therapy, and extracting migrated stents.

In the frame of a small scale concentrating solar power plant design and construction in Ouagadougou, an ORC （organic rankine cycle） machine is used to operate as a power block. In order to characterize the system and further optimize its operating conditions, a model is developed in this paper to describe the operating process of the thermodynamic cycle. The so-called model is obtained by interconnecting the mathematical models of its components. Then, simulations are conducted to determine the parameters that impact mostly the efficiency of the system. Furthermore, authors conducted an exergy analysis of the system to evaluate the exergy destruction of every component for a chosen operating condition.

Incorporating AOSD to Enhance Model Driven Architecture

引用

Journal of Software Engineering and Applications 2011年第1期4卷 18-22页

作者： Yashwant Singh manu Sood Tarun Gupta Atish Thakur 不详

Various software development approaches in the present scenario are best suited for a specific application. The software development strategies include both merits and demerits when talked in terms of generalization. The Model Driven Architecture (MDA) describes software development based on models on various levels of abstraction. The model driven software development process consists of sequence of model transformations between various models. This paper presents incorporation of the merits of Aspect Oriented Software Development (AOSD) like modularization, reusability and reduced complexity into Model Driven Architecture (MDA) software development strategy. The proposed Model Driven Software Development approach which combines the merits of MDA and AOSD meets the ever changing and challenging demand of the enterprise software development.
