Research on World Consciousness in Guo Moruo’s Poetry
This article starts from the world trend of thought absorbed by Guo Moruo, sorts out Guo Moruo’s world consciousness and the dynamic process of his acceptance of world trends, and explores the reasons why these advanced trends of thought were applied by Guo Moruo in combination with Guo Moruo’s life experience and spiritual life. Finally, the authors return to Guo Moruo’s poetry works and analyze how these ideological currents have brought about some important changes in his poetry creation, leading to some of his poetry works presenting new characteristics and becoming a revolutionary milestone in the history of literature
The site conditions of the Guo Shou Jing Telescope
The weather at Xinglong Observing Station, where the Guo Shou Jing Telescope
(GSJT) is located, is strongly affected by the monsoon climate in north-east
China. The LAMOST survey strategy is constrained by these weather patterns. In
this paper, we present a statistics on observing hours from 2004 to 2007, and
the sky brightness, seeing, and sky transparency from 1995 to 2011 at the site.
We investigate effects of the site conditions on the survey plan. Operable
hours each month shows strong correlation with season: on average there are 8
operable hours per night available in December, but only 1-2 hours in July and
August. The seeing and the sky transparency also vary with seasons. Although
the seeing is worse in windy winters, and the atmospheric extinction is worse
in the spring and summer, the site is adequate for the proposed scientific
program of LAMOST survey. With a Monte Carlo simulation using historical data
on the site condition, we find that the available observation hours constrain
the survey footprint from 22h to 16h in right ascension; the sky brightness
allows LAMOST to obtain the limit magnitude of V = 19.5mag with S/N = 10.Comment: 10 pages, 8 figures, accepted for publication in RA
The effects of halo alignment and shape on the clustering of galaxies
We investigate the effects of halo shape and its alignment with larger scale
structure on the galaxy correlation function. We base our analysis on the
galaxy formation models of Guo et al., run on the Millennium Simulations. We
quantify the importance of these effects by randomizing the angular positions
of satellite galaxies within haloes, either coherently or individually, while
keeping the distance to their respective central galaxies fixed. We find that
the effect of disrupting the alignment with larger scale structure is a ~2 per
cent decrease in the galaxy correlation function around r=1.8 Mpc/h. We find
that sphericalizing the ellipsoidal distributions of galaxies within haloes
decreases the correlation function by up to 20 per cent for r<1 Mpc/h and
increases it slightly at somewhat larger radii. Similar results apply to power
spectra and redshift-space correlation functions. Models based on the Halo
Occupation Distribution, which place galaxies spherically within haloes
according to a mean radial profile, will therefore significantly underestimate
the clustering on sub-Mpc scales. In addition, we find that halo assembly bias,
in particular the dependence of clustering on halo shape, propagates to the
clustering of galaxies. We predict that this aspect of assembly bias should be
observable through the use of extensive group catalogues.Comment: 8 pages, 6 figures. Accepted for publication in MNRAS. Minor changes

ASPECTUAL INFLUENCE ON TEMPORAL RELATIONS: A CASE STUDY OF THE EXPERIENTIAL GUO IN MANDARINE
This paper examines how the temporal relation between a clause containing the experiential guo and an adjacent clause is determined. Mandarin is a language not morphologically marked for tenses (e.g., Lin 2006), and therefore, tenses cannot help in determining temporal relations in Mandarin. However, Mandarin has a rich aspectual system. This paper argues that the experiential guo indirectly influences temporal relations via rhetorical relations by either specifying a default rhetorical relation, or by constraining the circumstances under which a certain rhetorical relation can connect a clause with guo to an adjacent clause. This paper also argues that the default rhetorical relation and the constraints are determined by the aspectual properties of the experiential marker. Other information, such as discourse connectors, lexical information, etc., can override the default rhetorical relation indicated by guo and specifies a rhetorical relation. Therefore, this paper concludes that in Mandarin aspect markers can indirectly affect temporal relations by means of rhetorical relations, a result consistent with Wu’s (2005b) paper on the perfective marker le in Mandarin, and Wu’s (2007b, 2004) work on the progressive marker zai and the durative marker zhe
