赵国置县考——以赵国兵器铭文和玺印考古资料为主

传统文献记载赵国县邑资料很少,难以窥见其全貌。但战国时赵国的文物中涉及赵县邑的资料不少,这为研究战国赵县邑提供了传世文献所不能见的重要史料。本文就是利用战国赵文物中兵器铭文和玺印有关资料,结合文献,考证战国时期赵国所置县邑,以补史书之缺佚。

试论国家主权的适应性让渡

国家主权对于一个主权国家来说具有十分重要的意义,“国家主权神圣不可侵犯”;然而在国际关系发展的新形势下,为了国家的整体利益,在自愿、独立决策的前提下,适应性地让渡出一部分主权是合理的,这与其说是让渡,不如说是一种积极的调整。     

Digital redesign tracker for cascaded analog systems with state saturation and external loads

This paper presents a newly developed digital redesign control scheme with a weighted switching strategy and output-reference tracking, for a cascaded analog system with state saturation and external loads. The proposed method improves the generally poor transition response and output deviation caused by state-saturation constraint and external loads. It replaces an existing or theoretically well-designed analog controller with state saturation, by a digital controller with almost identical performance.     

新时代西部大开发背景下职业教育思政教学方法内容初探

在中共中央国务院关于新时代推进西部大开发形成新格局的指导意见下,思政教学需要围绕西部地区区域特色,民族文化差异,产业结构等特点,发挥意识形态导向作用,制定符合国家政策发展需要的教学内容。对此,如何培养学生关心西部发展,进而能够发挥技能优势建设西部,是思政教学中存在的重难点。文章将围绕新时代西部大开发中需要深化的知识点以及如何将新时代西部大开发政策融入思政教学各环节进行探讨。     

Linear output-feedback-based semi-global stabilization for switched nonlinear time-delay systems

This paper focuses on the problem of semi-global output-feedback stabilization for a class of switched nonlinear time-delay systems in strict-feedback form. A switched state observer is first constructed, then switched linear output-feedback controllers for individual subsystems are designed. By skillfully constructing multiple Lyapunov–Krasovskii functionals and successfully solving several troublesome obstacles, such as time-varying delay and switching signals and nonlinearity in the design procedure, the switched linear output-feedback controllers designed can render the resulting closed-loop switched system semi-globally stabilizable under a class of switching signals with average dwell time. Furthermore, under some milder conditions on nonlinearities, the semi-global output-feedback stabilization problem for switched nonlinear time-delay systems is also studied. Simulation studies on two examples, which include a continuous stirred tank reactor, are carried out to demonstrate the effectiveness of the proposed approach.

新诗的“青果”——关于伪满洲国时期的《诗季》杂志

论文是对伪满洲国时期的一本中文诗歌杂志《诗季》的考述,藉此描画伪满洲国时期新诗发展的状貌,之一是探索长诗之＂长＂的种种可能,之二是寻求抒情小诗的诗形和诗质,形成独特的隐喻和象征秩序,之三是流寓满洲的日本诗人对离散空间中人的命运的诗歌书写。借非常时期的诗歌文本细读,触及那时文人的隐蔽心灵世界。     

Problems of secondary education in rural Iran: An anthropological view1

Statistics on implementing secondary education in rural Iran indicate that such a process has not been successful. Data gathered by the author during 1974/75 fieldwork support such a conclusion. It is suggested that lack of success of secondary education in rural Iran may be attributed to some cultural and economic factors which vary for men and women. The importance of the modesty code and observation of purdah (seclusio?) may account for the low enrollment of females in secondary education in rural areas. However, the need for agricultural laborers in the villages may account for the low attendance of males. Background to the development of modern education is presented.     

The role of fantasy figures in the regulation of young children's behavior: Santa Claus,the Easter Bunny,and donations

The present study examined the influence of Santa Claus and the Easter Bunny on children's donations near the Easter season. Kindergarten and first-grade children were asked to tell stories about Santa Claus, the Easter Bunny, or pets, for which they received nine pieces of gum. They were then encouraged to donate any amount of their gum to handicapped children. Main effects were found only for grade, with first-grade children donating significantly more than kindergarten children. In addition, a significant interaction was obtained between grade and type of story elicited from the child. This interaction revealed that for kindergarten children, the type of story failed to influence donations, whereas for first-grade children, stories referring to Santa Claus increased donations relative to stories told about the Easter Bunny or pets.
