对股份制的哲学思考

社会化大生产与生产资料私人占有的矛盾产生了股份制，股份制的产生出现了所有权与经营权的矛盾，为解决这一矛盾产生了股份制的运行机制。社会主义国家利用股份制的运行机制解决所有权与经营权的矛盾，建立了社会主义公有制的实现形式。股份制在社会主义国家的运用是一种历史的创造，必须在充分认识其规律的基础上大胆创新，不要被任何表面上的形式所束缚。     

基于自适应排序LDPC码的OFDM系统及其性能分析

为了在正交频分复用(OFDM)系统中充分利用非正则低密度奇偶校验(LDPC)码编码比特错误概率不同的特性,提出了一种新的基于自适应排序LDPC码的OFDM传输技术.假设发射机已知信道状态信息(CSI),非正则LDPC码的编码比特根据度进行排序,并被分配到相应的子载波上,度高的比特分配到轻度衰落的子载波,度低的节点分配到深度衰落的子载波.为了降低反馈信道的开销,可以对反馈的CSI进行量化.该传输技术的性能可以由密度演进算法进行分析.分析和仿真结果表明,相对于传统的无排序LDPC码编码OFDM系统,所提出的基于自适应排序LDPC码的OFDM系统可以获得1 ~1.5dB的性能增益,并且对CSI的量化具有鲁棒性.

论广告传播与文化的互动

广告文化是从属于商业文化的亚文化,自身又包含着商品文化及营销文化。广告活动不仅仅是一种经济活动,还是一种文化交流。文化因素对广告创意产生着深刻的影响,同时,在知识经济时代,随着信息技术的高速发展和互联网的广泛应用,广告对文化也产生了一定的互动。     

匹配视觉特性的频谱切割编码方法与计算机模拟

对一种适用于数字电视／高清晰度电视的三维视频编码方法进行研究，给出实验结果。与人眼视觉特性相匹配，该法对低频亮度分量采用全帧速率传输以保证良好的运动显示，对高频亮度分量以降低的帧速率传输，以保证静止图像的细节。实验表明，这种编码方案简单有效，是一种有前途的编码方案。     

Effects of motivational regulation strategies on writing performance: a mediation model of self-regulated learning of writing in English as a second/foreign language

Motivational regulation has long been recognized as an essential but insufficiently investigated aspect of self-regulated learning (SRL), especially in relation to learning English-as-a-foreign-language (EFL) writing. This study intends to fill the gap by investigating the predictive effect of motivational regulation strategies on EFL students’ writing performance mediated by SRL strategies. Data were collected from undergraduate students in mainland China (N = 512) through self-report questionnaires and an English writing test. Results of structural equation modeling (SEM) confirmed a partial mediation model in which motivational regulation strategies, as a whole, not only had direct and indirect effects on students’ writing performance but were also significantly correlated with their reported use of SRL strategies relating to cognition, metacognition, and social behavior. In addition, only cognitive and metacognitive strategies were found to be significant mediators in the model while social behavior strategies were not. The findings suggest that cumulative knowledge of motivational regulation is an antecedent of the reported use of other SRL strategies in affecting EFL writing performance. The inclusion of SRL strategies in the mediation model also contributes to a clear understanding of L2 writing processes within the SRL mechanism for improving writing outcomes.     

Career Development Among Ethnic and Age Groups of Community College Students

The purpose of this study was to examine differences in career development among four ethnic groups and two age groups of community college students in regard to their career goals, career preparation actions, and the number of job seeking strategies utilized. Data were obtained from the Beginning Postsecondary Students Longitudinal Study (BPS: 90/94) of the National Center for Educational Statistics (NOES), U.S. Department of Education. Results suggest that there are statistically significant differences among the ethnic groups in six of the seven career goals; however, there are no significant differences between the traditional and non-traditional age groups in career goals. For career preparation action there are significant differences between the two age groups and also between Black/African American and White/European American students. There is no significant difference among the age or ethnic groups in the number of job seeking strategies utilized. These findings imply that student services providers, such as counselors, should be sensitive to community college students' backgrounds and experiences related to ethnicity and age. Individualized career-related workshops tailored to the career needs of specific student populations should be offered. The function of community colleges as providers of employment preparation can be enhanced by familiarizing students with accurate career information, considering students' ethnic backgrounds and their age.

民族地区学生英语习得中的制约因素

语言习得有其规律和特征，研究习得有助于我们更好地组织开展语言教学。但民族地区学生因“地”受制，英语的习得除常见因素干扰外，方言、教育环境、生活环境等也对他们习得英语有较强的影响和制约。分析、研究这些制约因素有利于改变、提高民族地区的英语教学水平。     

科学与人文关系的思考
