对某奶牛场16头乳牛产前10 d至产后56 d血样的瘦素、酮体、葡萄糖、脂肪水平及其动态特征和相关性进行了检测。结果表明,血浆瘦素、血酮、血脂含量在不同乳牛和不同时间点之间均有显著差异。酮体在产后14~49 d出现高峰,瘦素和血脂从产后第0 d到产后第56 d内逐渐升高。瘦素水平与血脂水平呈极显著正相关,血酮与血糖呈极显著负相关。亚临床酮病组乳牛的瘦素和血脂水平分别极显著或显著低于血酮正常组,其瘦素、血酮和血糖在试验期内的波动频率明显减少,跨度变长,瘦素在试验期内仅出现一个两端接近0、波峰不超过1.5 ng/mL的波。证实,产后乳牛瘦素、血酮、血糖含量的低频率波动变化和产后8周内血浆瘦素跨时持久的单峰动态变化与乳牛亚临床酮病的发生有关。 相似文献

East Asia, including Northeast Asia and Southeast Asia, has developed tightly-linked production/distribution networks through
globalizing corporate activities. The vertical chain of production in East Asia has been even more sophisticated than economic
integration in East Europe or Latin America. However, the political environment of East Asia for trade and investment has
been far from borderless. The integration effort at the policy level has been very much limited so far, due to the historical
background as well as geopolitics surrounding East Asia.
The Asian currency/financial crisis provided these countries a historical turning point. After the burst of the crisis, East
Asians realized that they have to take care of themselves in their difficulties, not depending on outside forces. A natural
choice for them was to step into the realm of regionalism. In 1998, Japan and Korea officially announced that they would discard
the long-lasting GATT/WTO-only approach and adapt the multi-layered approach, including both regionalism and multilateralism.
The ultimate goal of regionalism would be a region-wide integration including ASEAN+3. As a steppingstone, Japan signed the
Japan-Singapore Economic Partnership Agreement (JSEPA) in January 2002. In a parallel move, the ASEAN and China Leaders announced
in November 2001 the establishment of an ASEAN-China Free Trade Area (ACFTA) within 10 years.
This article will follow up the most recent advancement of regional institutional building in East Asia with the emphasis
on peculiar characteristics of economic integration in the region and discuss its implications for Asia-Europe relations.
This paper is heavily drawn from Kimura (2002, 2003). 相似文献

This paper links the policy context regarding S&T parks to the objectives and characteristics of the established parks and
incubators in a relatively small, converging European country. S&T parks and incubators in Greece during the past decade and
a half have gradually shifted in terms of ownership and management from university/research institute to the private sector
and in terms of financing from public to private funds, also involving the provision of seed capital and access to venture
capital. This gradual shift toward more private engagement has created a variety of models out of which, it is hoped, successful
innovative companies will emerge in larger numbers than in the past.

This paper reviews the existing literature on consumer credit reporting, the most extensively used instrument to overcome
information asymmetry and adverse selection problems in credit markets. Despite the copious literature in economics and some
research in regulatory policy, the legal community has paid almost no attention to the legal framework of consumer credit
information systems, specially within the context of the European Union. Studies on the topic, however, seem particularly
relevant in view of the establishment of a single market for consumer credit. This article ultimately calls for further legal
research to address consumer protection concerns and inform future legislation.

This article offers an analysis of the European airline industry in order to understand the new dynamics of the competitive
field. The liberalization process did not lead the entrance of competitors similar to incumbents, but a new organizational
model has been developed, the one of low cost carriers. The incumbents’ reaction to the liberalization process coupled with
the entrance of low cost companies into the sector are hence considered. Two theories are analysed: the contestable markets
theory, to understand the theoretical vision that has influenced the liberalization process, and the core theory, a modern
approach to the concept of destructive competition that, according to some authors, is a recurring problem in the sector.
While numerous barriers to entry still exist, the paper examines how the organizational model of low cost companies has helped
new entrants to overtake these obstacles. By the same token, the application of the core theory does not seem to justify strategic
alliances taking place in these years. The competitive framework is definitely clearer if we analyse sector changes in a different
way, from the point of view of low cost companies considered as new market actors. 相似文献

This article contributes to the development of theories on European integration by testing and exploring statistical models
on the long-term development of legislative activity of the European Commission. Drawing on legal information gained from
the European Union’s PreLex database and analyzing it with the help of statistical analyses, we map out growth patterns of EU law between 1976 and 2003.
We construct time-series models and models based on non-linear regression. While the performance of models based on the traditional
theoretical approaches, intergovernmentalism and neo-functionalism, is rather poor, the analysis suggests that nonlinear dynamic
models might be an interesting avenue for future conceptualizations of the EU integration process.
This article is based on a paper presented at the ECPR Standing Group on the European Union Second Pan-European Conference on EU Politics, “Implications of a Wider Europe: Politics, Institutions and Diversity”, 24–26 June 2004, Bologna, Italy. We would like to
thank the seminar participants for useful comments. 相似文献

Banks are “special” financial institutions generating distinct corporate governance challenges. The present paper examines
the relationship between two of the most pertinent corporate governance factors—that is, the size of the Board of Directors
and the proportion of non-executive directors—and firm performance on a sample of 58 large European banks over the period
2002–2004. The empirical analysis embraces a number of bank-specific variables. Our results reveal that bank profitability
is negatively related to the size of the Board of Directors, while the impact of Board composition, although positive in all
models, is, in most cases, insignificant. The results are robust after controlling for firm-specific variables.
