基于MATLAB的数字信号处理实践教学研究

数字信号处理是一门理论性较强的专业课程,公式推导多,学生对某些理论知识点理解困难。本文将MATLAB引入实践教学当中,对课堂教学、实验教学、课程设计等方面的实施实例进行阐述。本文提出的实践教学研究思路能对提高教学效果、提升学生的动手能力起到很好的促进作用。     

马克思主义三化的思考

党的十七届四中全会报告提出：＂要大力推进马克思主义中国化、时代化、大众化＂,这是中国对马克思主义理论品格的新论断,对于党和国家事业的发展具有重大的现实意义和长远意义。然而这三者并不是孤立进行的,是相伴相随的。因此,在推动社会主义理论建设过程中,要理解三者的定义,进一步理清三者间的关系,为推进马克思主义理论创新和实践应用开辟新的思路。

The impact of cash transfers on household welfare in Namibia

Namibia has a long history of providing a universal and non-contributory old age pension, child grants using means testing and quasi-conditionalities, and other cash transfers. Multivariate analysis presented in this paper confirms that these transfers play an important role in alleviating poverty, especially for the very poor. The poverty-reducing effects of the child grants are likely to increase further as access is being rapidly expanded. However, the impact in terms of reducing Namibia's extremely high inequality is limited. The targeting of the cash transfers towards the poorest groups takes place through two main channels. For the child grant, targeting occurs as a result of the orphan status eligibility criteria, as orphans are over-represented in lower-income households. For the universal social pension, it appears that some of the relatively less poor do not receive it even if they are eligible. Means testing of child grants appears ineffective, even without considering administrative costs.     

美国人何以养老——美国养老保险体系与可持续研究

美国的养老保险体系是由国家通过税收筹资的基本养老基金、企业建立的以401(k)计划和个人退休帐户(IRAs)为主的职业养老金计划以及相当完善的商业养老保险共同构成的三支柱式养老保险体系。通过具体分析美国国家基本养老和企业职业养老基金的构成、收入来源、支出水平以及可持续能力,说明美国养老保险体系是一个制度完善、可持续能力较强的养老保险范例,值得我国借鉴。     

独立学院数码钢琴集体课的教学与教育初探

数码钢琴集体课是传统钢琴教学与现代高新科技（计算机技术、光电技术、数字处理技术、音频采样技术）相结合而发展起来的一门新型教学方式,以学习钢琴弹奏为基本目的,采用＂一对多＂集体课的授课方式,以渗透乐理、视唱练耳、和声编配、简易作曲、即兴伴奏等为教学内容的全新学习途径。它的产生丰富了钢琴教学手段、改革了授课形式、完善了教学内容,不仅是对传统＂一对一＂教学的补充,更是钢琴教育在方法和思想上的一个突破。

中国退休年龄面临的挑战与选择

中国退休年龄总体偏低,需要逐步提高退休年龄。欧洲一些国家提高退休年龄引发动荡,警醒中国应尽快将提高退休年龄纳入议程,并稳步推进改革。建议用较长的时间逐步将男职工退休年龄提高到63岁,将女职工退休年龄提高到60岁。并通过采取实行弹性退休和抑制提前退休等措施,为逐步提高退休年龄打下基础。     

Core decisional values and deciders demographic variables in Romanian organizauons

The present study attempts to build an exploratory model of leadership analysis, based on which the organizational leaders and managers can answer three critical questions for leadership practice： （1） Which are the core decisional values the top management should take into account when adopting critical decisions？ （2） Which latent attitudes （constructs or factors） might generate these values in CEOs＇ and followers＇ behavior？ （3） Do the latent attitudes differ with the respondents＇ gender, age and educational background？ The research belongs to the field of value based leadership theories. The data is collected from a sample of 94 CEOs and 599 direct followers from three complex fields of activity： mining and forestry, manufacturing and construction, respectively, services. The main outcomes are： （1） The most important decisional values should be （in order）： customer satisfaction, firm＇s profitability, product/service quality, sales volume growth and cost control; （2） These values are generated by the following latent attitudes （of CEOs and followers）： social responsibility for community and environment; ethical responsibility for minorities and women; market performance responsibility and, respectively, responsibility for employees and customers; （3） Market performance responsibility significantly differs according to respondents gender; social responsibility for community and environment significantly differs with respondents age, while both types of responsibility significantly differ according to respondents educational background. It seems that ethical responsibility for minorities and women and, respectively, responsibility for employees and customers are not influenced by respondents＇ demographic variables.
