关键词： 银行发展   企业技术创新   作用效果   省际面板数据  

摘要： 商业银行是我国企业技术创新过程中获取外部资金的重要渠道。利用我国各省市2000～2009年的时间序列数据,通过面板数据模型检验了银行发展对企业技术创新的作用效果,结果表明:银行发展对企业技术创新具有显著的促进作用,但其作用效果受到市场化程度等非金融因素的限制。加快金融体制的市场化改革将会更好地发挥商业银行对企业技术创新的促进作用。

关键词： 家族所有权   家族控制   企业绩效   传承意愿   长期投资  

摘要： 家族所有权如何影响家族企业的短期逐利和长期投资行为?通过对2010年全国私营企业抽样调查数据库的1574家中小型家族企业,在不同家族传承意愿下的长短期影响进行的分组检验显示,无论是否有意家族传承,家族所有权与短期利益总是显著正相关,而仅有意传承的家族所有权会促进长期投资,无意家族传承的家族所有权对长期投资的积极性不足。这表明,在家族企业的长短期决策中,一定的短期利益是得以生存和发展的前提,而仅有意家族世代传承的家族所有权才获得长期投资的激励。

关键词： authoritarianism   beliefs   causes of crime   goals of sentencing   punishment   rehabilitation  

摘要： Community attitudes can impact on sentencing policy. This study investigated attitudes and beliefs regarding sentencing goals in an Australian sample comprising 128 men and 178 women. Regression analyses showed that endorsement of punishment as a sentencing goal was predicted by lower education, higher authoritarianism and the belief that crime is caused by offenders' personal characteristics. Support for rehabilitation was predicted by beliefs attributing the causes of crime to economic conditions in society and by higher confidence in the criminal justice system. A more complex picture was obtained by clustering scores on the punishment and rehabilitation dimensions. Respondents clustered into four distinct groups: High Punishment/Low Rehabilitation, High Punishment/High Rehabilitation, Mid Punishment/Mid Rehabilitation and Low Punishment/High Rehabilitation. These groups differed significantly on study variables. Overall, results suggested that not all individuals simply endorse either punishment or rehabilitation as goals of sentencing. The dimensional approach may add to current understanding of people's support for differing goals of sentencing.

摘要： Classification is one of the important tasks in bioinformatics. This can be obviously seen in cancer classification which is recently addressed by many researchers specially after emerging of microarrays. This technology opens the way for computer researchers to classify cancer samples without any previous biological knowledge. Microarrays data is facing a critical challenge because of the nature of high-dimensional and small sample size this problem forces scientists to design gene selection techniques as a preceding step to the implemented classifier. Feature selection is the assignment of selecting a small subset from original features that can perform maximum classification accuracy. This subset of features has some very important benefits such as; it reduces computational complexity of learning algorithms, improves accuracy and save time. In this paper we propose a hybrid feature selection techniques that performed in two phases. In the first phase we use ensemble filter method to ranking all genes and select top genes. This phase helps in improving the classification performance by removing redundant and unimportant features. In the second phase we used SVM-RFE (Recursive Feature Elimination) is a wrapper method. We evaluated our technique on three data sets of gene expression profiles; the Leukemia, the Lung and the Breast cancer; using six classifiers, which are Naive Bayes (NB), Random Forest (RF), Decision Trees (C4.5), Support Vector Machines (SVM), K-Nearest Neighbor (KNN) and Logistic Regression (LR) and show the potentiality of the proposed method with the advantage of improving the classification performance.

关键词： Obligations (Law)   Interpretation & construction of contracts   Legal instruments   Contracts -- United States   Contracts -- Economic aspects  

摘要： In developing a contractual response to changes in the economic environment, parties choose the method by which their innovation will be adapted to the particulars of their context. These choices are driven centrally by the thickness of the relevant market-the number of actors who see themselves as facing similar circumstances-and the uncertainty related to that market. In turn, the parties' choice of method will shape how generalist courts can best support the parties' innovation and the novel regimes they envision. In this Article, we argue that contractual innovation does not come to courts incrementally, but instead reaches courts later in the innovation's evolution and more fully developed than the standard picture contemplates. Highly stylized, the trajectory of innovation in contract we find is this: Private actors respond to exogenous shocks in their economic environments by changing existing structures or procedures to make them efficient under the new circumstances. The innovating parties stabilize their newly emergent practices through a variety of regimes-both bilateral and multilateral-with the goal of establishing the context through which the innovation is implemented. It is only at this point, and when a dispute is presented to them, that courts step in. If contract innovation does indeed reach generalist courts through the mediating institution of these contextualizing regimes, then our argument follows directly: Because a central goal of contract adjudication is to enforce the agreement in the context the parties intended, the courts' willingness to defer to the context provided by the parties will put the law more directly in the service of innovation.

关键词： Developmental disabilities   Parenting behaviors   Autism  

摘要： This study examined the extent to which child syndromes and observation context related to mothers' parenting behaviors. Longitudinal observations were conducted of parenting behavior across ages 3, 4, and 5 years during structured and unstructured activities. The 183 participants included mothers of children with autism spectrum disorders, cerebral palsy, Down syndrome, undifferentiated developmental delay, or typical cognitive development. Negative parenting behaviors were higher in structured activities and higher in mothers of children in all developmentally delayed groups. Positive parenting was higher in unstructured activities and especially high for mothers of children with Down syndrome. Despite differences found through direct observation of parenting children in different diagnostic groups, they are not as strong as syndrome-group differences found through more commonly used self-report questionnaires assessing domains like parenting stress.

关键词： BIOLOGICAL specimens -- Collection & preservation   METHODOLOGY   ADENOCARCINOMA   PRESERVATION of organs, tissues, etc.  

摘要： The authors discuss the implications of the new classification of adenocarcinoma. They cite 2 articles by Dr. Travis and colleagues which address the issue of conservation of small tissue samples for testing. They state that these 2 articles support the new classification of pulmonary adenocarcinomas which is a big step toward integrating clinical, radiologic, and molecular features into the pathologic classification of lung cancer.

关键词： Time series classification   Autoregressive models   Bias-adjusted AR estimators   Small samples   Hypothesis testing  

摘要： A new test of hypothesis for classifying stationary time series based on the bias-adjusted estimators of the fitted autoregressive model is proposed. It is shown theoretically that the proposed test has desirable properties. Simulation results show that when time series are short, the size and power estimates of the proposed test are reasonably good, and thus this test is reliable in discriminating between short-length time series. As the length of the time series increases, the performance of the proposed test improves, but the benefit of bias-adjustment reduces. The proposed hypothesis test is applied to two real data sets: the annual real GDP per capita of six European countries, and quarterly real GDP per capita of five European countries. The application results demonstrate that the proposed test displays reasonably good performance in classifying relatively short time series. (c) 2012 Elsevier B.V. All rights reserved.
