谈谈学分制下如何做好学生党建工作

全面推行学分制是高校教学改革的深化,是教育和教学改革的一个发展阶段.但由于学分制所带来的思想教育、学生党建等新情况、新问题,应值得所有教育者认真思考和研究的.本文围绕学分制实行后给学生党建工作带来的"四难"以及如何应对提出了一些理论和实践的思考.     

Has the rise in globalization reduced U.S. inflation in the 1990s?

This article investigates whether increased globalization of the U.S. economy has helped hold down inflation in the 1990s. Based on several measures, we find that globalization has increased. Further, we find that import prices exert a greater impact on prices of products in industries faced with greater import penetration. High foreign excess capacity accounts for much of the recent decline in U.S. inflation. Our results suggest that the decline in inflation is explained by the interaction of increased globalization and high excess foreign capacity. Globalization by itself does not lead to less inflation, just greater sensitivity to foreign economic conditions.     

蒙古国的民族问题与民族政策

蒙古国的民族构成以蒙古族为主,占总人口的90％以上,蒙古族内的十几个部族虽然在方言、风俗习惯和服饰上有所差别,但能自由交流。哈萨克、乌梁海、图瓦、霍屯等突厥民族只占6％多一点。蒙古国民族问题的主要表现是哈萨克族的迁徙问题。在1991-1992年间就有4.1万人迁居到哈萨克斯坦国。迁徙的主要原因：一是蒙古国历届政府对民族理论和民族宗教政策的研究落实不得力;二是受国际大气候的影响,泛民族主义意识抬头。针对这种情况,蒙古国政府采取了协商解决一切问题的方针,及时出台了一些政策法规,收到了较好的成效。     

Does Asymmetry of International Shocks Matter for the U.S. Business Cycle?

This article proposes and investigates the asymmetry hypothesis, which predicts that an international asymmetric shock tends to have a stronger and longer effect on the U.S. business cycle than a symmetric shock. The hypothesis finds empirical support in the impulse responses of U.S. output and inflation to symmetric and asymmetric shocks; those responses are estimated in a four-variable structural vector autoregression. The hypothesis also finds support in stylized facts: The longest U.S. expansions have tended to occur when the rest of the world was growing below potential.     

新世纪粤台产业合作的结构分析与策略探讨

过去20多年来,由于特殊的地缘条件和良好的经济基础设施与产业配套条件,粤台两地具有进行经济资源整合和产业结构互补的良好条件,广东也成为台商在大陆投资最集中的省份,台商投资结构演化和粤台产业合作取得长足的发展,但也存在台资企业的产业关联度不高,台资企业的技术溢出和学习效应不明显和台商投资软环境有待改善等问题。进入新世纪,广东应进一步调整对台商投资的产业导向,优化台商投资结构,重点引进台湾大企业投资,努力提高广东本地企业对台资企业的产业配套能力。     

YOUTUBE,TWITTER AND THE OCCUPY MOVEMENT

Videos stored on YouTube served as a valuable set of communicative resources for publics interested in the Occupy movement. This article explores this loosely bound media ecology, focusing on how and what types of video content are shared and circulated across both YouTube and Twitter. Developing a novel data-collection methodology, a population of videos posted to YouTube with Occupy-related metadata or circulated on Twitter alongside Occupy-related keywords during the month of November 2011 was assembled. In addition to harvesting metadata related to view count and video ratings on YouTube and the number of times a video was tweeted, a probability sample of 1100 videos was hand coded, with an emphasis on classifying video genre and type, borrowed sources of content, and production quality. The novelty of the data set and the techniques adapted for analysing it allow one to take an important step beyond cataloging Occupy-related videos to examine whether and how videos are circulated on Twitter. A variety of practices were uncovered that link YouTube and Twitter together, including sharing cell phone footage as eyewitness accounts of protest (and police) activity, digging up news footage or movie clips posted months and sometimes years before the movement began; and the sharing of music videos and other entertainment content in the interest of promoting solidarity or sociability among publics created through shared hashtags. This study demonstrates both the need for, and challenge of, conducting social media research that accommodates data from multiple platforms.     

嵌入式智能滑动轴承研究

针对目前的滑动轴承状态监测系统传感器在现场安装位置受限,离信号源头较远,不容易获得可靠的状态信息, 文章提出一种新型的智能轴承结构,在滑动轴承上嵌入温度、转速、振动等传感器,并在DSP上实时处理轴承的工作状 态信息。嵌入式的智能传感器安装在轴承外圈,更接近于信号的源头,因此智能轴承的传感器能获得比滑动轴承更准确 的状态信息,因DSP信号处理部件与传感器紧密配合,在实时处理信号方面更有优势。经实验验证,智能轴承比传统的 轴承状态检测系统更能有效地提取状态信息和故障诊断信息。     

Where is the Fed in the distribution of forecasters?

Previous research comparing the Fed's Greenbook forecasts with a median forecast from a private-sector panel has found that the Fed's forecasts are superior. These comparisons potentially miss information from other parts of the distribution of forecast errors. We compare the Fed's forecast errors to the upper and lower quartiles from the Survey of Professional Forecasters’ forecast errors and find that errors in the lower quartile are significantly smaller. We further investigate whether the forecasters who produced those forecast errors can be identified ex-ante and find that while possible the practicality of this finding is limited due to forecaster turnover.     

The Public Sphere and the End of American Abolitionism, 1833–1870

Real prejudice existed among white abolitionists and within the operations of interracial organisations like the American Anti-Slavery Society (AASS). Yet an understanding of these organisations that attributes their inevitable doom to fundamental racism shortchanges the accomplishments of the AASS and predicts the same result for such later interracial associations as the National Association for the Advancement of Colored People (NAACP). This article applies theoretical formulations of associational life in the public sphere to consider the birth and death of the AASS between 1833 and 1870, the final years of abolitionism in the United States, in terms of the fulfillment of the purposes established at its founding, concluding that its dissolution was less racist than logical.     

Measurement of changes: What criteria do we adopt?

Many changes in industrial working methods are now under discussion which are not easily evaluated and management is concerned about the probable return from investing in these methods. It is proposed that, whilst it is clear that improving work performance is a benefit, it is also of benefit to achieve changes in attitudes which correlate more closely with the objectives and state of the enterprise. Increased agreement in this respect is stated to lead to increased stability for the production process as there is less likelihood of disruption of output due to inappropriate decisions and actions. Since the loss due to various forms of interruption in output can be assessed it is described how the benefit of attitude change might thus be measured. A model for the relationships relevant to ergonomic and behavioural science changes in industry is given and its potential is illustrated by examples.
