多重网络中的词学研究

近20年来,词学研究有所进展,但仍存在一些问题。词学研究应在多重网络中展开。首先,词学是专门之学,但研究者仍需建构开放的知识网络。词乐研究虽有不少成果,但仍处于相对低潮。这与研究者受限于音乐知识,无法有效介入有关。词谱、词律等专门之学亦是如此。其次,可以尝试词学研究的时空延展,打造通观的“全息网络”,通过长时段的、大量的文本分析发现新话题。同时,注意域外汉籍,因为它们可以提供新文献,启发新视角,丰富文本网络。最后,要注意数字人文的发展趋向,要建设词学检索库,善用新技术,更新研究理念,以便及时因应。但数字人文终究只是辅助研究手段,技术取代不了阅读与思考,只有在传统研究的基础上,技术才能发挥更大的作用。     

Speech at the UN International Conference on Population,Mexico City,August, 1984

In seeking a solution to its population problem, China, as a developing socialist country, has been making unremitting efforts to develop economy while controlling the rapid growth. The objective is to control rapid population growth so that population growth may be in keeping with socioeconomic development and commensurate with utilization of natural resources and environmental protection. In the past decade, and particularly since 1979, China has made much progress in developing economy and gained remarkable successes in controlling population growth. The natural population growth rate dropped to 1.15% in 1983, from 2.089% in 1973. Living standards have improved with a gradual annual increase of per capita income. All this proves that the policy of promoting family planning to control population growth along with planned economic development is correct. In China family planning is a basic state policy. The government has advocated the practice of "1 couple, 1 child" since 1979. This does not mean that 1 couple could have 1 child only in every case. The government provides guidance for the implementation of family planning programs in the light of specific conditions such as economic developments, cultural background, population structure, and the wishes of the people in different localities. The requirements are more flexible in rural than in urban areas and more so among the people of national minorities than among the people of the Han Nationality. In rural areas, couples who have actual difficulties and want to have 2 children may have a 2nd birth with planned spacing. In carrying out its family planning program, China has consistently adhered to the principle of integrating state guidance with the masses' voluntariness. The government has always emphasized the importance of encouraging the people's own initiatives, through publicity and education, which is the key link in implementing the family planning program.     

A study on mortality rates and expectation of life at birth in demography]

An "age-time-area diagram" (referred to as a-t diagram) which is used as the basis for discussing different used and applications of variously defined mortality rates, as well two kinds of measurements for life expectancy is proprosed. The proposal is built upon the Lexis diagram. The a-t diagram is used to define a new way of measuring child mortality, projecting population, and proposing a formula for measuring successive and nonsuccessive life expectancy.

《南开管理评论》1998年-2002年引文分析研究

本文采用引文分析方法对《南开管理评论》1998年-2002年所发表的论文的引文进行了统计分析,从引文量、引文语种、引文类型、引文年代、引文期刊、引文著者等几个方面做了综合评价,其目的是从文献引证的角度来透视该刊的学术水平和期刊质量,并从中寻求一些带有规律性的结论,为期刊的编辑出版提供一些参考。     

"五四"新文学运动前二十年文学理论批评文体的演进

文学理论批评文体是文学理论批评形式特征的总和。中国古代文论文体有其鲜明的特色 ,但也有明显的局限性。至近代 ,尤其是五四新文学运动前二十年 ,文学理论批评文体发生了巨大的变化。其变革的方向 ,总的来说是向现代文学理论批评文体演进。具体来看 ,体式向多样化、大容量发展 ;篇章结构趋向完整精致 ;语言文字趋向通俗浅显 ;对西方文体从模仿趋向融会贯通 ;文体的外在形式向规范化发展     

加快建设宁波国际远洋集装箱中转枢纽港的发展思路和实施步骤及对策

我国是世界经济增长重心第五次大转移的主要增长极，长江三角洲地区将发展成为世界第六个特大城市带。这都要求把宁波港建设成为上海国际航运中心的远洋集装箱中转枢纽港。实现这个目标的基本思路及时策：沪、甬、舟三港联合起步形成组合港；成立杭州湾大通道开发公司并尽快建成杭州湾大通过；宁波港建成自由港（区）或实行自由港（区）主要政策；港口附近建几个外向型商品市场。     

Minimum power assignment in wireless ad hoc networks with spanner property

Power assignment for wireless ad hoc networks is to assign a power for each wireless node such that the induced communication graph has some required properties. Recently research efforts have focused on finding the minimum power assignment to guarantee the connectivity or fault-tolerance of the network. In this paper, we study a new problem of finding the power assignment such that the induced communication graph is a spanner for the original communication graph when all nodes have the maximum power. Here, a spanner means that the length of the shortest path in the induced communication graph is at most a constant times of the length of the shortest path in the original communication graph. Polynomial time algorithm is given to minimize the maximum assigned power with spanner property. The algorithm also works for any other property that can be tested in polynomial time and is monotone. We then give a polynomial time approximation method to minimize the total transmission radius of all nodes. Finally, we propose two heuristics and conduct extensive simulations to study their performance when we aim to minimize the total assigned power of all nodes.

Flow shop scheduling with deteriorating jobs under dominating machines

This paper addresses no-wait or no-idle flow shop scheduling problems with deteriorating jobs, i.e., jobs whose processing times are an increasing function of their starting time. A simple linear deterioration function is assumed and some dominating relationships between machines can be satisfied. It is shown that for the problems to minimize makespan or weighted sum of completion time, polynomial algorithms still exist, although these problems are more complicated than the classical ones. When the objective is to minimize maximum lateness or maximum tardiness, the solutions of a classical version may not hold.     

回报计划感知价值及其与计划忠诚和品牌忠诚的关系研究

目前,客户回报计划已成为一种重要的关系营销手段,相关问题也开始引起学术界的关注。本文研究了回报计划的不同形式是如何影响客户对计划的感知价值的,同时回报计划的感知价值又是如何影响计划忠诚和品牌忠诚的,并且在研究的过程中考虑了产品或服务对客户涉入度的调节作用。结果显示,仅回报类型对计划感知价值的影响受到涉入度的调节,强涉入度下直接回报优于间接回报;而回报时间和回报额度对计划感知价值的影响不受涉入度的调节,延迟回报和差额回报优于立即回报和等额回报。同时,在强涉入度情况下,回报计划的感知价值通过直接和间接两务途径影响品牌忠诚;而在低涉入度争件下,回报计划感知价值对品牌忠诚没有直接影响,而是通过计划忠诚间接影响品牌忠诚。
