A key to the all species of this genus is provided.

中华双腔吸虫（Dicrocoelium Chinensis Tang et Tang，1978）（Trematoda：Digenea）卵子发生的超微结构研究

利用透射电镜技术观察了中华双腔吸虫（ＤｉｃｒｏｃｏｅｌｉｕｍｃｈｉｎｅｎｓｉｓＴａｎｇｅｔＴａｎｇ，１９７８）的卵巢结构和卵子发生过程，同时提出了划分复殖吸虫卵子发生过程的标准，总结了复殖吸虫卵子发生的一般规律以及中华双腔吸虫卵子发生的特有特征。此外比较分析了不同复殖吸虫的皮质颗粒特征，指出它在分类上可能有重要意义。中华双腔吸虫卵巢和卵子发生的超微结构与大多数复殖吸虫相似，但其卵巢中的各生殖细胞间有网状片层结构及一些颗粒、膜状碎片等支持和营养结构，还有退化的成熟卵母细胞。中华双腔吸虫的卵子发生分为卵原细胞

用微细胞技术转移鱼类遗传因子初报

<正> 自Ege等(1974)的工作开始,在70年代已逐步建立起一种通过微细胞把一个细胞的染色体转移到另一个细胞中,并作为在杂种细胞里起作用的遗传因素,永远地保留下去的技术。后来,Illmensee等(1978)把带有一个人类染色体的小鼠细胞注射到小鼠胚泡腔中,当该胚泡发育成个体后,在一些组织中测出了人类特

Phylogeny of diplozoids in five genera of the subfamily diplozoinae palombi, 1949 as inferred from ITS-2 rDNA sequences

The phylogenetic relationship of 5 genera, i.e. Diplozoon Nordmann, 1832, Paradiplozoon Achmerov, 1974, Inustiatus Khotenovsky, 1978, Sindiplozoon Khotenovsky, 1981, and Eudiplozoon Khotenovsky, 1985 in the subfamily Diplozoinae Palombi, 1949 (Monogenea, Polyopisthocotylea) was inferred from rDNA ITS-2 region using neighbour-joining (NJ), maximum likelihood (ML) and Bayesian methods. The phylogenetic trees produced by using NJ, ML and Bayesian methods exhibit essentially the same topology. Surprisingly, freshwater species of Paradiplozoon from Europe clustered together with species of Diplozoon, but separated from Chinese Paradiplozoon species. The results of molecular phylogeny and lower level of divergence (4(.)1-15(.)7%) in ITS-2 rDNA among Paradiplozoon from Europe and Diplozoon and, on the other hand, high level of divergence (45(.)3-53(.)7%) among Paradiplozoon species from Europe and China might indicate the non-monophyletic origin of the genus Paradiplozoon. Also, the generic status of European Paradiplozoon needs to be revised. The species of Paradiplozoon in China is a basal group in Diplozoinae as revealed by NJ and Bayesian methods, and Sindiplozoon appears to be closely related to European Paradiplozoon and Diplozoon. with their relationship to Eudiplozoon and Inustiatus being unresolved.

陕西省汉台区1978年至2006年耕地数量变化及驱动力分析

汉台区是陕西省农业产业结构调整典型示范区,近年来,由于农业产业结构调整、退耕还林还草和建设占用耕地,汉台区耕地数量大量减少,耕地供需矛盾突出。本文利用1978年以来汉台区耕地长序列统计资料和近9年的土地详查与变更数据,研究汉台区土地利用现状及其结构变化、分析汉台区耕地数量变化的基本过程及空间差异、探讨耕地数量变化的主要驱动力。研究结果表明:①1978年～2006年全区耕地共减少5600hm2,平均每年减少200hm2,人均耕地减少0.027hm2,耕地递减率曲线与人均耕地递减率曲线走势基本一致;②建设占用耕地、退耕还林还草和农业结构调整等直接影响因子在4种类型区影响耕地变化差异明显;总体上,农业产业结构调整是全区耕地减少的主导因素,经济发展较快的城镇,建设占用耕地较多;③耕地面积与社会经济发展各因素间的相关系数约低于累计耕地面积与各因素之间的相关系数,说明全区耕地减少与社会经济发展存在时间上的错位性,即经济和社会发展滞后于对耕地资源的占用。

The temporal and spatial evaluation on China's agricultural policy output since 1978

Since reform and opening up, how much contribution has China's implementation of new agricultural policy made to agricultural output? This paper is trying to establish an agricultural policy output econometric model for doing a quantitative analysis of China's new agricultural policy. The results show that China's agricultural policies on agricultural output have an average contribution rate of about 7% since 1978, which is consistent with the OECD's basic forecast. There are obvious temporal and spatial differences. Generally speaking, we can divide the contribution of agricultural policy into three periods, which are the start-up phase from 1978 to 1991 (14 years), the stationary phase from 1992 to 2002 (11 years) and the rising phase from 2003 to 2008 (6 years). In space, the contribution of agricultural policy underwent a process from the all-low in the start-up phase, the gradual increase in the stationary phase to the all-high in the rising phase. Northern and western regions are more sensitive to policies. There are three major factors that can affect the contribution of regional agricultural policies, which are the process of national industrialization strategy, terrain and the level of local finance.

The Ford administration, Angola and the perception of Post-Vietnam US credibility, 1974-1976

This thesis is a study of how the Gerald Ford administration struggled to address a perceived loss of US credibility after the collapse of Vietnam, with a focus on the role of Secretary of State Henry Kissinger in the formulation, implementation and subsequent defence of US Angolan policy. By examining the immediate post-Vietnam period, this thesis shows that Vietnam had a significant impact on Kissinger’s actions on Angola, which resulted in an ill conceived covert operation in another third world conflict. In 1974, Africa was a neglected region in Cold War US foreign policy, yet the effects of the Portuguese revolution led to a rapid decolonization of its African territories, of which Angola was to become the focus of superpower competition. After South Vietnam collapsed in April 1975, Kissinger became fixated on restoring the perceived loss of US prestige, Angola provided the first opportunity to address this. Despite objections from his advisors, Kissinger methodically engineered a covert program to assist two anti-Marxist guerrilla groups in Angola. As the crisis escalated, the media discovered the operation and the Congress decided to cease all funding. A period of heated tensions ensued, resulting in Kissinger creating a new African policy to outmanoeuvre his critics publicly, while privately castigating them to foreign leaders. This thesis argues that Kissinger’s dismissal of internal dissent and opposition from the Congress was influenced by what he perceived as bureaucrats being affected by the Vietnam syndrome, and his obsession with restoring US credibility. By looking at the private and public records – as expressed in government meetings and official reports, US newspaper and television coverage and diplomatic cables – this thesis addresses the question of how the lessons of Vietnam failed to influence Kissinger’s actions in Angola, but the lessons of Angola were heavily influential in the construction of a new US-African policy.

A GLOBAL SAMPLING OF PIANO MUSIC FROM 1978 TO 2005

Pianists of the twenty-first century have a wealth of repertoire at their fingertips. They busily study music from the different periods -- Baroque, Classical, Romantic, and some of the twentieth century -- trying to understand the culture and performance practice of the time and the stylistic traits of each composer so they can communicate their music effectively. Unfortunately, this leaves little time to notice the composers who are writing music today. Whether this neglect proceeds from lack of time or lack of curiosity, I feel we should be connected to music that was written in our own lifetime, when we already understand the culture and have knowledge of the different styles that preceded us. Therefore, in an attempt to promote today’s composers, I have selected piano music written during my lifetime, to show that contemporary music is effective and worthwhile and deserves as much attention as the music that preceded it. This dissertation showcases piano music composed from 1978 to 2005. A point of departure in selecting the pieces for this recording project is to represent the major genres in the piano repertoire in order to show a variety of styles, moods, lengths, and difficulties. Therefore, from these recordings, there is enough variety to successfully program a complete contemporary recital from the selected works, and there is enough variety to meet the demands of pianists with different skill levels and recital programming needs. Since we live in an increasingly global society, music from all parts of the world is included to offer a fair representation of music being composed everywhere. Half of the music in this project comes from the United States. The other half comes from Australia, Japan, Russia, and Argentina. The composers represented in these recordings are: Lowell Liebermann, Richard Danielpour, Frederic Rzewski, Judith Lang Zaimont, Samuel Adler, Carl Vine, Nikolai Kapustin, Akira Miyoshi and Osvaldo Golijov. With the exception of one piano concerto, all the works are for solo piano. This recording project dissertation consists of two 60 minute CDs of selected repertoire, accompanied by a substantial document of in-depth program notes. The recordings are documented on compact discs that are housed within the University of Maryland Library System.
