试论高校教师智力资本的特点与核算方法

高校教师的劳动实际上是消耗人的智力资本.在知识经济时代,其劳动方式不会改变,但获得报酬的方式却由传统的平均分配转为智力资本的分配,智力资本的积累也就成了高校教师的必然选择.对高校教师智力资本进行科学的动态核算,会使高校智力资本分配方式趋向合理性.

《茗柯词》变相《风》、《骚》创作意格--论清代常州词派代表张惠言的创作实践

张惠言是清代常州词派的开创者,他以传统儒家之"忠爱悱恻、不淫不伤之旨"为其词学理论基础;以<风>、<骚>的文学精神为其创作典范"感士不遇"而又"主文谲谏",寻春惜春,以立意为本,咏物抒情,重比兴寄托.主张崇比兴,区正变,知尊体.张惠言的<茗柯词>基本上体现了他这一词论要旨.     

A study on cyclic bandwidth sum

Suppose G is a graph of p vertices. A proper labeling f of G is a one-to-one mapping f:V(G)→{1,2,…,p}. The cyclic bandwidth sum of G with respect to f is defined by CBS _f (G)=∑ _uv∈E(G)|f(v)−f(u)| _p , where |x| _p =min {|x|,p−|x|}. The cyclic bandwidth sum of G is defined by CBS(G)=min {CBS _f (G): f is a proper labeling of G}. The bandwidth sum of G with respect to f is defined by BS _f (G)=∑ _uv∈E(G)|f(v)−f(u)|. The bandwidth sum of G is defined by BS(G)=min {BS _f (G): f is a proper labeling of G}. In this paper, we give a necessary and sufficient condition for BS(G)=CBS(G), and use this to show that BS(T)=CBS(T) when T is a tree. We also find cyclic bandwidth sums of complete bipartite graphs.

Distance graphs on R n with 1-norm

Suppose S is a subset of a metric space X with metric d. For each subset D⊆{d(x,y):x,y∈S,x≠y}, the distance graph G(S,D) is the graph with vertex set S and edge set E(S,D)={xy:x,y∈S,d(x,y)∈D}. The current paper studies distance graphs on the n-space R ₁ ⁿ with 1-norm. In particular, most attention is paid to the subset Z ₁ ⁿ of all lattice points of R ₁ ⁿ . The results obtained include the degrees of vertices, components, and chromatic numbers of these graphs. Dedicated to Professor Frank K. Hwang on the occasion of his 65th birthday.

Assessing the impact of new technology in information systems

Computer and communication technology is changing at an increasing rate. New technologies are emerging: the price- performance of current technology is improving. There is a need to assess the impact of technology on new information systems projects, particularly those dealing with distributed processing and electronic office systems. Such an assessment provides direction and guidance in long range and intermediate term information services planning. It can potentially prevent costly conversion efforts. An approach is developed for obtaining this assessment. Two case examples of applications are provided which illustrated the method, results and benefits.     

高效液相色谱法测定葡萄酒中白藜芦醇的含量

利用高效液相色谱法测定样液中的白藜芦醇含量,采用乙腈水为流动相,检测波长306nm,分析测定了葡萄酒中白藜芦醇的含量。结果表明,葡萄酒中检测到白藜芦醇检出限为0.05mg/L,加标回收率达98.5%。该方法简便、快速、准确度高、前处理简单、能够满足葡萄酒中白藜芦醇的分析要求。     

论康德的自由主义政治哲学

康德的政治哲学奠定于道德哲学基础上 ,其实质是自由主义的法权哲学 ,其中一对核心范畴是自由与秩序 ,涉及道德自由与自然秩序、政治自由与法律秩序、意志自由与政治法律秩序三种不同逻辑层面的表现形式。他的自由主义政治哲学思想在不同方向和层面上对后世产生了深刻影响     

节约型高校建设与示范

节能减排已成为当代社会科学发展的主旋律。高校节约型校园建设是应＂两型校园建设＂的要求,并作为一项长期工作写入了多数高校总体规划中,实现节支和绿色生态校园的双赢。大学作为社会文明与进步的播火者,在国家国策的践行中,同样可率先垂范和培养具生态文明理念的接班人。要固守低碳生活的理念,将节俭美德作为高校育人的重要内容。该文将对正在进行的节约型校园建设,提供一些有益的经验参照。     

Hazards regression for freemium products and services: a competing risks approach

We propose a competing risks approach to analyse customer behaviours in freemium products and services. The event of interest is when a customer starts to pay for additional features or functionalities. The observation of such an event may be preempted by an event where the customer quits using the product before paying and consuming the additional features or functionalities. One such freemium service is the online game category. The Fine-Gray regression model was implemented for an online game player activity data to study how covariates affect the paying hazard. Some covariates are hypothesized to have different discrete effects at multiple change points. We extend the model to allow for possible change points in the analysis.
