我国金融控股公司立法必要性探析   总被引:1,自引:0,他引:1  
金融控股公司作为我国金融“分业”体制下实现“混业经营”目的的一种组织创新模式,在我国的发展日益迅速,而我国立法空缺的现状却严重阻碍了其健康发展,也造成了极大的金融风险。文章利用历史分析、比较分析和法经济学的方法,通过对我国金融业历史发展演进的纵向考察,对世界金融控股公司普遍立法现状的横向比较以及金融控股公司作为一种经济组织形式与我国金融立法关系的分析,论证了我国金融控股公司立法的必要性。  相似文献

作为刑事被告人人权保障的一个方面,现代法治国家普遍尊重并在不同程度上赋予了被告人以程序选择权--即在法定范围内,被告人有权依自己的意愿选择刑事诉讼的有关程序及与程序有关的事项,具体如对审判程序的选择和对审判方式的选择.虽然程序选择权未被表述为被告人最基本、最重要的诉讼权利,但因其有着广泛的理论依据从而具备了存在和发展的正当性,故在我国的刑事诉讼中也应当受到重视.  相似文献

美国制裁国际卡特尔的赦免制度介评   总被引:1,自引:0,他引:1  
美国反垄断部门出台的赦免制度在制裁国际卡特尔方面发挥着极为重要的作用,该制度规定参加卡特尔的公司中第一个向政府揭发该卡特尔的公司可免除刑事责任。赦免制度有效实施的基础包括三个方面,即管辖地的反垄断法必须对参与卡特尔的公司制定严厉的惩罚措施、卡特尔成员面临着被反垄断部门查处的巨大风险、赦免制度具有透明度和可预见性。美国的赦免制度已相当成熟和完善,实践也证明这一制度具有极大的应用价值,这对于我国制定反垄断法、有效制裁国际卡特尔具有重要的借鉴意义。  相似文献

Variable selection in elliptical Linear Mixed Models (LMMs) with a shrinkage penalty function (SPF) is the main scope of this study. SPFs are applied for parameter estimation and variable selection simultaneously. The smoothly clipped absolute deviation penalty (SCAD) is one of the SPFs and it is adapted into the elliptical LMM in this study. The proposed idea is highly applicable to a variety of models which are set up with different distributions such as normal, student-t, Pearson VII, power exponential and so on. Simulation studies and real data example with one of the elliptical distributions show that if the variable selection is also a concern, it is worthwhile to carry on the variable selection and the parameter estimation simultaneously in the elliptical LMM.  相似文献

In confirmatory clinical trials, the prespecification of the primary analysis model is a universally accepted scientific principle to allow strict control of the type I error. Consequently, both the ICH E9 guideline and the European Medicines Agency (EMA) guideline on missing data in confirmatory clinical trials require that the primary analysis model is defined unambiguously. This requirement applies to mixed models for longitudinal data handling missing data implicitly. To evaluate the compliance with the EMA guideline, we evaluated the model specifications in those clinical study protocols from development phases II and III submitted between 2015 and 2018 to the Ethics Committee at Hannover Medical School under the German Medicinal Products Act, which planned to use a mixed model for longitudinal data in the confirmatory testing strategy. Overall, 39 trials from different types of sponsors and a wide range of therapeutic areas were evaluated. While nearly all protocols specify the fixed and random effects of the analysis model (95%), only 77% give the structure of the covariance matrix used for modeling the repeated measurements. Moreover, the testing method (36%), the estimation method (28%), the computation method (3%), and the fallback strategy (18%) are given by less than half the study protocols. Subgroup analyses indicate that these findings are universal and not specific to clinical trial phases or size of company. Altogether, our results show that guideline compliance is to various degrees poor and consequently, strict type I error rate control at the intended level is not guaranteed.  相似文献

Non-Gaussian spatial responses are usually modeled using spatial generalized linear mixed model with spatial random effects. The likelihood function of this model cannot usually be given in a closed form, thus the maximum likelihood approach is very challenging. There are numerical ways to maximize the likelihood function, such as Monte Carlo Expectation Maximization and Quadrature Pairwise Expectation Maximization algorithms. They can be applied but may in such cases be computationally very slow or even prohibitive. Gauss–Hermite quadrature approximation only suitable for low-dimensional latent variables and its accuracy depends on the number of quadrature points. Here, we propose a new approximate pairwise maximum likelihood method to the inference of the spatial generalized linear mixed model. This approximate method is fast and deterministic, using no sampling-based strategies. The performance of the proposed method is illustrated through two simulation examples and practical aspects are investigated through a case study on a rainfall data set.  相似文献

Many research fields increasingly involve analyzing data of a complex structure. Models investigating the dependence of a response on a predictor have moved beyond the ordinary scalar-on-vector regression. We propose a regression model for a scalar response and a surface (or a bivariate function) predictor. The predictor has a random component and the regression model falls in the framework of linear random effects models. We estimate the model parameters via maximizing the log-likelihood with the ECME (Expectation/Conditional Maximization Either) algorithm. We use the approach to analyze a data set where the response is the neuroticism score and the predictor is the resting-state brain function image. In the simulations we tried, the approach has better performance than two other approaches, a functional principal component regression approach and a smooth scalar-on-image regression approach.  相似文献

Population aging is a phenomenon occurring across the globe including in countries traditionally exhibiting population dividends and “youth bulges.” The Gulf Corporation Council countries are no exception as they currently experience a process of population aging, albeit at a different stage from many developed countries. However, due to historically high fertility rates and fast-paced epidemiological transition, some of these countries will experience population aging at a higher pace than what has been observed in Europe and the United States. This article reviews recent developments in long-term care policies in the Gulf region with a focus on Oman as an example of a high-income Arab country that is experiencing population aging while still being governed by traditional family aged-care norms. Utilizing existing data and published research complemented by policy analysis and field visits, we analyze the process of population aging in Oman and neighboring countries and its policy implications.  相似文献

This article provides a succinct overview of the phenomenon of solidarization in crisis‐ridden Greece. Brief accounts of the pre‐ and post‐crisis situation in four core social policy areas (health, employment, housing, education) are combined with the presentation of four illustrative case studies, one for each of the aforementioned areas. Drawing on a broad range of primary and secondary data, including 20 in‐depth interviews with key stakeholders and end‐users of the actions examined, we argue that while the crisis provoked a further “residualization” of the institutionalized solidarity system, it also triggered the development of new solidarity ventures, both by state and non‐state actors, often even including partnerships between them. These ventures reflect the building of a bridge between institutionalized and informal solidarity in Greece and the shift towards a new type of mixed, although fragmented, mode of solidarity.  相似文献

企业通过对拥有旧产品的老消费者提供以旧换新补贴能够提升自身销量与利润。然而,面临竞争对手时企业的以旧换新决策是否会受到影响?本文求解了先后进入市场的双寡头竞争企业所面临的以旧换新与定价博弈均衡,并分析了竞争存在与否对于企业以旧换新策略产生的影响。研究结果表明,第一,面对竞争时企业的定价决策受到市场中老消费者比例、两家竞争企业各自新产品的创新提升水平、老产品的使用残值这四个因素的共同影响。第二,当老产品残值相对较低而市场中老消费者数量适中时,两企业均不提供以旧换新可能成为博弈均衡,而其他条件下,两企业均提供以旧换新为博弈均衡。第三,先进入的企业没有动机单独为消费者提供以旧换新补贴。第四,竞争对手的存在对于先进入企业自身的以旧换新决策与相应的定价策略都产生了显著的影响。  相似文献
