A Planned Jefferson Lab Experiment on Spin-Flavor Decomposition

Experiment E04-113 at Jefferson Lab Hall C plans to measure the beam-target double-spin asymmetries in semi-inclusive deep-inelastic $\vec p(e, e^\prime h)X$ and $\vec d(e, e^\prime h)X$ reactions ($h=\pi^+, \pi^-, K^+$ or$K^-$) with a 6 GeV polarized electron beam and longitudinally polarized NH$_3$ and LiD targets. The high statistic data will allow a spin-flavor decomposition in the region of $x=0.12 \sim 0.41$ at $Q^2=1.21\sim 3.14$ GeV$^2$. Especially, leading-order and next-to-leading order spin-flavor decomposition of $\Delta u_v$, $\Delta d_v$ and $\Delta \bar{u} - \Delta \bar{d}$ will be extracted based on the measurement of the combined asymmetries $A_{1N}^{\pi^+ - \pi^-}$. The possible flavor asymmetry of the polarized sea will be addressed in this experiment.Comment: 4 pages, 2 figures, contribution paper to SPIN2004 conferenc

Soft Power to Whom? A Critical Analysis of the Publicity Film “CPC (Communist Party of China) is With You Along the Way” in Relation to China’s Soft Power Project

The existing literature on China’s soft power is mainly concerned with its success or failure, ignoring the ideological tensions between the Chinese state's international pursuit of soft power and its efforts at reviving the popularity of socialist ideology at home in a country profoundly transformed by modernisation and globalisation processes. This article argues that such ideological tensions should be contextualised and critically analysed by employing an approach informed by critical globalisation studies, particularly by the power-to-whom critique. It offers a critical analysis of the CPC is With You Along the Way film, a notable recent example of the CPC’s publicity videos in the context of its pursuit of soft power. Borrowing Reisigl and Wodak’s discourse-historical approach (DHA) in addition to the analytical devices for the study of ideology from Eagleton and van Dijk, the article argues that CPC is With You Along the Way illustrates a shift in the party’s ideological approach to the question ‘(soft) power to whom?’

Polarization of AGN in UV Spectral Range

We present the review of some new problems in cosmology and physics of stars in connection with future launching of WSO. We discuss three problems. UV observations of distant z > 6 quasars allow to obtain information on the soft < 1 KeV X-ray radiation of the accretion disk around a supermassive black hole because of its cosmological redshift. Really the region of X-ray radiation is insufficiently investigated because of high galactic absorption. In a result one will get important information on the reionization zone of the Universe. Astronomers from ESO revealed the effect of alignment of electric vectors of polarized QSOs. One of the probable mechanism of such alignment is the conversion of QSO radiation into low mass pseudoscalar particles (axions) in the extragalactic magnetic field. These boson like particles have been predicted by new SUSY particle physics theory. Since the probability of such conversion is increasing namely in UV spectral range one can expect the strong correlation between UV spectral energy distribution of QSO radiation and polarimetric data in the optical range. In the stellar physics one of the interesting problems is the origin of the X-ray sources with super Eddington luminosities. The results of UV observations of these X-ray sources will allow to find the origin of these sources as accreting intermediate mass black holes.Comment: 6 pages, 3 figure

Adoption of e-commerce by the agri-food sector in China: the case of Minyu e-commerce company

In recent years, increasing numbers of smallholders in developing countries such as China have begun to sell agricultural products directly to consumers via online shops using a third-party trade platform. It is increasingly clear that e-commerce has become a new and effective way to help smallholders gain access to the market. The investigation of agricultural e-commerce practices has a significant role in helping to understand the development of the agri-food sector in China. This teaching case provides an example of adopting e-commerce in the interaction and trading activities between participants in the food sector through a typical agricultural products e-commerce company in China, Minyu E-commerce. Particularly, the case analyzes the business model evolution through the ecosystem life cycle at the company. This case can be used to teach graduate/postgraduate students in agricultural business, MBA and executive programmes about the agri-food e-commerce business model

Vaule-added Erosion in Global Value Chains: Rethining International Trade

The prevalence of vertical specialization and global value chains (GVCs) demands that we think differently about international trade and its relationship to employment. This talk discusses employment effects of GVCs trade. Dr. Jiang argues that the expansion of foreign high value-adding activities in the upper stream of GVCs is likely to lead to a decline of domestic value-added share, leading to intensification of international and domestic distributional conflicts. Dr. Xiao Jiang’s research combines mathematical modeling, simulations and statistics with classical political economy. He has provided economic consulting for the International Labor Organization, the Association for East and Southeast Asian Countries, and the Economic Policy Institute. Dr. Jiang holds a PhD. in Economics from The New School for Social Research.https://corescholar.libraries.wright.edu/econ_seminars/1000/thumbnail.jp

Acoustic detection of air shower cores

At an altitude of 1890m, a pre-test with an Air shower (AS) core selector and a small acoustic array set up in an anechoic pool with a volume of 20x7x7 cu m was performed, beginning in Aug. 1984. In analyzing the waveforms recorded during the effective working time of 186 hrs, three acoustic signals which cannot be explained as from any source other than AS cores were obtained, and an estimation of related parameters was made
