本研究以中国学术期刊网1994-2003年间的公共关系论文为第一手资料，结合国内新闻传播6大权威学术期刊相同年份的公共关系论文，运用内容分析法，从研究属性、研究主题、理论视角以及研究方法4个方面对国内近10年来公共关系研究进行定量研究和跨文化分析。研究发现，到2003年8月止．中国公共关系理论研究水平正处在美国20世纪70年代中期的水平，公共关系学科也正处在由不成熟向成熟过渡的转型期，整体理论研究水平落后于世界25-30年。  相似文献   

Improving the precision of the keyword-matching pornographic text filtering method using a hybrid model     

苏贵洋  李建华  马颖华  李生红 《浙江大学学报(A卷英文版)》2004,5(9):1106-1113

With the flooding of pornographic information on the Internet, how to keep people away from that offensive information is becoming one of the most important research areas in network information security. Some applications which can block or filter such information are used. Approaches in those systems can be roughly classified into two kinds:metadata based and content based. With the development of distributed technologies, content based filtering technologies will play a more and more important role in filtering systems. Keyword matching is a content based method used widely in harmful text filtering. Experiments to evaluate the recall and precision of the method showed that the precision of the method is not satisfactory, though the recall of the method is rather high. According to the results, a new pornographic text filtering model based on reconfirming is put forward. Experiments showed that the model is practical, has less loss of recall than the single keyword matching method, and has higher precision.  相似文献   

死刑执行救济程序研究     

孟军  白永利 《广播电视大学学报》2006,4(4):78-81

死刑执行救济程序是限制死刑适用的途径之一。我国的死刑执行救济需要在《刑法》中增设判处死刑的被告人有权请求赦免或减刑的条款,赋予救济的实体依据;《刑事诉讼法》中明确死刑执行救济的决定权主体和适用对象,明确特赦和减刑理由及其程序,明确死刑判决生效到执行之间适当的时间间隔。  相似文献   

语言学非现实词词义研究综述     

曾柱 《培训与研究》2006,23(9):12-14

语言学上对“鬼”、“神”、“妖魔”、“上帝”这一类非现实词的词义谈得比较少。本文通过对20世纪60年代初至90年代语言学上关于非现实词词义研究作综述后,认为语言学学者在研究非现实词词义这一问题上分为两大派别:一方认为非现实词词义有所谓而无所指;另一方认为非现实词词义有所谓也有所指。  相似文献   

A Multipart Project Planning and Tracking Exercise     

Thomas R. Robbins 《Decision Sciences Journal of Innovative Education》2019,17(2):104-125

Project Management is an important skill for business students to develop. Although project‐oriented activity is very common, the success rate for projects is poor. Many projects fail due to poor planning. This article describes a multipart class exercise used to teach elements of a project management methodology to undergraduate and graduate business students. Over the course of the eight‐part exercise, student teams iteratively develop a project plan and Gantt chart, an initial and detailed project charter, a variance analysis model, and a status report. Students are taught an iterative top‐down planning process using a technique we term the ODW (Objectives–Deliverables–Workplan) model. Students are introduced to Microsoft Project and use the tool to develop a project plan that becomes part of a more detailed Project Charter. In the final stages of the exercise, students collect results, update their plan, and produce a project status report.  相似文献   

Helping Business Students Acquire the Skills Needed for a Career in Analytics: A Comprehensive Industry Assessment of Entry‐Level Requirements     

Wilbur W. Stanton  Angela D'Auria Stanton 《Decision Sciences Journal of Innovative Education》2020,18(1):138-165

Fact‐based decision making is changing job functions within organizations more than any other technology. Analytics, once the purview of the data scientist, is now spread throughout organizations. No longer is there a single job title, job function, or set of required skills and credentials for an analytics career. Companies have moved away from seeking applicants with a specific degree to now recruiting analytics talent based on required skill sets. For more than a decade, business schools have been developing new programs in analytics in response to industry's needs. However, in developing meaningful career‐ready professionals, business programs must understand the skills required across different analytics job functions. In this article, the authors present a comprehensive assessment of the skills sought by employers when considering a candidate for an entry‐level analytics position. The authors describe the demand for various types of analytics professionals, identify the job titles and functions with the most significant demand, and then draw a comparison of the job requirements of hard skills, soft skills, software skills, and credentials between three of the most sought‐after analytics areas: data science, data analytics, and business analytics. The authors conclude by providing faculty and administrators with recommendations on how to adapt their courses and programs to provide students with the fundamental preparation necessary for careers in data science, data analytics, and business analytics.  相似文献

Learning mathematics for teaching in the student teaching experience: two contrasting cases     

Blake E. Peterson  Steven R. Williams 《Journal of Mathematics Teacher Education》2008,11(6):459-478

Student teaching (guided teaching by a prospective teacher under the supervision of an experienced “cooperating” teacher) provides an important opportunity for prospective teachers to increase their understanding of mathematics in and for teaching. The interactions between a student teacher and cooperating teacher provide an obvious mechanism for such learning to occur. We report here on data that is part of a larger study of eight student teacher/cooperating teacher pairs, and the core themes that emerged from their conversations. We focus on two pairs for whom the core conversational themes represent disparate approaches to mathematics in and for teaching. One pair, Blake and Mr. B., focused on controlling student behavior and rarely talked about mathematics for teaching. The other pair, Tara and Mr. T., focused on having students actively participating in the lesson and on mathematics from the students’ point of view. These contrasting experiences suggest that student teaching can have a profound effect on prospective teachers’ understanding of mathematics in and for teaching.

Use of the Rasch measurement model to explore the relationship between content knowledge and topic-specific pedagogical content knowledge for organic chemistry     

Bette Davidowitz  Marietjie Potgieter 《International Journal of Science Education》2016,38(9):1483-1503

Research has shown that a high level of content knowledge (CK) is necessary but not sufficient to develop the special knowledge base of expert teachers known as pedagogical content knowledge (PCK). This study contributes towards research to quantify the relationship between CK and PCK in science. In order to determine the proportion of the variance in PCK accounted for by the variance in CK, instruments are required which are valid and reliable as well as being unidimensional to measure person abilities for CK and PCK. An instrument consisting of two paper-and-pencil tests was designed to assess Grade 12 teachers CK and PCK in organic chemistry. We used the Rasch measurement model to convert raw score data into interval measures and to provide empirical evidence for the validity, reliability and unidimensionality of the tests. The correlation between CK and PCK was estimated as r = .66 (p < .001). We found evidence to suggest that while topic-specific PCK (TSPCK) develops with increasing teaching experience, high levels of CK can be acquired with limited teaching experience. These findings support the hypothesis that CK is a requirement for the development of TSPCK; proficiency in CK is, however, not necessarily associated with high levels of TSPCK.  相似文献   

论先前知识与英语阅读教学     

余凯明 《读与写:教育教学刊》2007,4(12):115-116

在英语教学中学习者的先前知识,或图式知识是影响外语学习的重要因素。因此能否激活图式至关重要。图式包括三种形式:语言图式,内容图式和形式图式。传统"自下而上"和"自上而下"的阅读模式只强调其中某一种图式的激活,交替模式则主张将两种模式结合的阅读模式。因此,在英语阅读教学种教师不仅要注重激活学生的语言图式,更要注重其内容和形式图式的激活。  相似文献
