FSH使用方法对无角道塞特绵羊超数排卵的影响

为探讨FSH的种类、剂量及注射次数和注射季节对绵羊超数排卵的影响,采用中国科学院动物所、宁波、加拿大生产的FSH对206只无角道塞特绵羊进行了超排处理,观察了供体发情率、回收胚胎数、可用胚胎数、退化胚及未受精卵比率以及供体的表现。结果,无论那种FSH,在适当的剂量范围都可有效进行超排,中国科学院FSH与宁波FSH联合使用可提高回收胚胎数和可用胚胎数;与6次递减注射相比,7次或8次递减注射的结果更为理想;秋季的超排效果优于春、夏和冬季。供体对激素处理表现复杂多变的超排反应,同时也出现卵子受精失败现象。结果表明,外源FSH只能在一定程度上控制超排反应,进一步的研究应考虑外源性FSH与内分泌反应的关系。     

Capturing the Regional Economic Benefits of University Technology Transfer: A Case Study

Despite a high concentration of brainpower and federally funded research, some universities have been unable to translate these assets into regionally based economic activity. The author uses an ethnographic method interviewing university officials and academic entrepreneurs in New York City, which has a relatively poor record of local start-up creation. The author finds that universities that view the primary objective of technology transfer as a revenue generator for their institutions generate fewer spin-offs than those that incorporate a local economic development component. Internal advocacy and faculty interest, however, can affect university behavior. The author also finds that academic entrepreneurs with a pre-existing affiliation with the licensing institution are more likely to locate in the area than outsiders utilizing the technology. Entrepreneurs exhibit a distinct locational calculus based on a range of variables including real estate costs, founders’ preference and the geographical proximity of key firm relationships.      

Managing Complex Collaborative Projects: Lessons from the Development of a New Satellite

This paper examines the case of a Complex Product System (CoPS)—a new satellite—and the combination of international firms and agencies that contributed to its development. Despite many political, organisational and interpersonal tensions, divergent objectives and strategic misjudgements, the satellite was successfully launched in 2002. It was found that a number of factors contributed to the successful conclusion of the project, including the evolution of organisational structures between different actors as the project progressed, the use of a range of innovation management tools accompanied by personnel with significant discretion and judgement, and a unifying methodology for satellite production called the Small Satellite Philosophy (SSP), which helped provide an approach for its effective integration. The paper describes the satellite project and the problems of technology transfer it confronted, then examines whether the solutions adopted could be appropriate for other complex innovative projects, particularly those involving joint public–private investments. It also describes the interaction between development time, mission cost, risk and return in reduced resource CoPS. Although the satellite itself was a technical success, government policy objectives for the project were not realised and the paper considers mismatches between policy objectives and mechanisms in complex projects.

DNA transfer during social interactions

Multiple DNA transfer has increasingly been brought up in court as potential means for the presence of the defendants DNA at the crime scene or on a piece of evidence. This has prompted several investigations into DNA transfer under very controlled and semi-controlled conditions, however little is published about DNA transfer in “uncontrolled” or real life situations.Here we examined the effects of multiple direct and indirect transfer of DNA within a small group of people and objects: three individuals participating in a social interaction of having a drink (jug of juice) together for 20 min. At the end of the tests all the surfaces of interest were sampled and analyzed.In many instances the last person or the only person to come in contact with the object was the main or the only depositor of the DNA detected on it. The jug was a clear vector for secondary DNA transfer. Interestingly, in many instances the participants acted as vectors for foreign DNA transfer.     

反向住房抵押贷款——以房养老的新模式探析

反向住房抵押贷款是为了使老年人将房屋抵押后仍可以继续居住,以实现养老或者增加老年人收入的模式设计,因涉及老年人的养老问题,社会影响较大。文章首先阐明了反向住房抵押贷款的概念和特征,分析其法理基础,与相关概念进行比较,再结合中国的具体国情,分析反向住房抵押贷款制度在我国实行的可行性和障碍,从法律的角度来研究反向住房抵押贷款。

本文在认真研究国内外产业转移理论及长三角产业转移趋势的基础上,分析影响宣城承接产业选择的因素。实证分析证明,宣城示范区与长三角存在产业发展层次的互补,可以探索打破行政区划和利益协调机制,构建多层次、宽领域、合作与竞争的区域经济合作新机制。     

营业转让中债权人利益的保护

我国现有对债权人保护的立法相对滞后,法出多门致使法律法规之间配套性差,导致债权人的债权实现愈加困难。文章对现行营业转让债权人利益保护的相关立法进行了梳理,并对构建我国营业债权人利益的保护提出了合理化建议。     

再论指示交付及其后果

中国物权法第26条关于指示交付的规定有利有弊，对于其利，必应否定；对于其弊，在解释论上，应最大限度地限缩其中所言“法”的范围，将若干第三人无权占有的情形视为“依法”，而不作为“违法”对待。不宜一概否定指示交付场合让与物权的返还请求权。“出让人转让被人盗窃或遗失的手表一块，此时转让的返还请求权应包括对第三人的所有物返还请求权”之说，是合适的，不应否认。     

论破产法上的偏颇性清偿

偏颇性清偿常常与欺诈性转让行为一同在破产撤销权的框架下被讨论,但二者间有本质的不同。偏颇性清偿有其自身的特点,是破产法上独有的概念,并且偏颇性清偿规则有其深刻的理论基础,是破产法的核心内容之一。深入研究偏颇性清偿规则的制度逻辑和设计原理,对完善我国破产法的偏颇性清偿规则具有重要意义。
