试论“苏道”与“海道”评弹的特征差异及共生关系

"海道"评弹的出现大致以1908年上海"申江润余社"的成立为标志。厥后,向以正统自诩的光裕社即调用种种手段遏制以润余社为代表的这股异己势力,从而引发了书坛数十年的"苏""海"之争。在互竞雄长的过程中,两者渐由组织上的区别发展为艺术及艺人气质上的分野。分析沪上评弹的特征,可见"海道"评弹实则是在上海"近商摄利"之风影响下,从苏州评弹中异化出的变体。这一变体在相当程度上反作用于母体,使苏沪评弹在彼此排斥的同时,形成了相生相长的共生关系。

Scale-free Structure of Town Road Network in Southern Jiangsu Province of China

From the viewpoint of Graph Theory this paper builds a town road network graph of regional scale, and proposes numerical vertex degree （Di）, rank vertex degree （Dr） and population size vertex degree （Dp） on the base of vertex degree （D）. Then the indicators of Di, Dr, Op and mathematical statistics methods are applied to investigating scale-free structure of town road networks in the southern Jiangsu Province. The results show that the distribution of Oi does not exhibit scale-free properties, but Dr and Dp do. Additionally the correlation coefficient between Dp and Di is only 0.569, but the spatial correlation between Dp and Dr is very evident on the base of correlation analysis and spatial analysis of GIS. The mutual mechanism between Dp and Dr spatially represents a ＂Core-Belt＂ model of town development of regional scale. The town development model is open and clustered, and beneficial to both economic development and ecological protection. And then we suggest that Suzhou City, Wuxi City, Changzhou City and Wujin City control towns＇ high-density pattern by conducting centralization and consolidation policies, and properly controlling and planning higher rank roads; whereas Nanjing City, Zhenjiang City, Jintan City and Liyang City must strengthen the development of towns along higher rank roads.

Effects of Dietary Stachyose on Growth Performance, Digestive Enzyme Activities and Intestinal Morphology of Juvenile Turbot(Scophthalmus maximus L)

A 12-week feeding trial was conducted to evaluate the effects of dietary stachyose on the growth performance, digestive enzymes activities and intestinal structures of juvenile turbot(Scophthalmus maximus L). Five isonitrogenous(49.58% crude protein) and isolipidic(10.50% crude lipid) diets were formulated to contain 0(Control), 0.625%(S-0.625), 1.25%(S-1.25), 2.5%(S-2.5) and 5%(S-5) stachyose, respectively. With the increase of stachyose level, the growth performance and feed utilization of turbot, such as the specific growth rate, final mean body weight, weight gain rate and feed efficiency, increased significantly(P < 0.05) and then stabilized. The feed intake of fish fed S-5 was significantly higher(P < 0.05) than that of fish in other groups. The activities of trypsin, intestinal caseinolytic, stomach and intestinal amylase were significantly influenced by stachyose(P < 0.05). The highest values of trypsin and intestinal caseinolytic activities were observed in group S-1.25, while the highest activity of stomach amylase and the lowest activity of intestine amylase were observed in group S-5. No lesion or damage was found on the distal intestine structures of fish from all treatments, while the height of simple folds in the distal intestine was significantly increased(P< 0.05) when 1.25% or 2.5% stachyose was added in the diets. These results indicated that moderate level of stachyose(1.25%) improves the growth performance, feed utilization, digestive enzyme activities and the distal intestine structures of juvenile turbot.

Honour, Virtue and Oppression in Ann Radcliffe＇s The Castles of Athlin and Dunbayne

Georgian historiography being an attempt to create a shared and self-congratulatory impression of the past serves as verbal equivalent of a national monument. Ann Radcliffe＇s Castles of Athlin and Dunbayne was written during the acme of popularity of gothified histories. This makes the novel a high drama of murder and revenge, usurpation and restoration, love and abduction, cruelty and virtue upholding common people＇s vow of joining hands to fight for ethical cause of avenging oppression against the backdrop of the Scottish highlands. On the one hand, the novel helps in perpetuating nationalist identity among English citizens by acclaiming virtuous, just, and moral act of the rightful feudal Chief Osbert and declaiming in contrast the avarice, oppression and lust of the usurper Malcolm. On the other hand, the self-devastating pride and calm resignation of the highborn women such as Mary and Louisa portrayed in the novel conform and thereby contribute to the notion of the ＂Angel in the House＂. The paper, thus, will examine the role of prevalent sense of honour and values imbibed in the major characters of the novel in bringing justice to the oppressed characters.

Multi-cell massive MIMO transmission with coordinated pilot reuse

In this paper, we propose a coordinated pilot reuse(CPR) approach to reduce the pilot overhead for multi-cell massive multi-input multi-output transmission. Unlike the conventional multi-cell pilot reuse approach in which pilots can only be reused among different cells, the proposed CPR approach allows pilots to be reused among both inter-cell and intra-cell user equipments, and thus, pilot overhead can be efficiently reduced. For spatially correlated Rayleigh fading channels, we first present a CPR-based channel estimation method and a low complexity pilot allocation algorithm. Because CPR might lead to additional pilot interference, we develop a statistically robust uplink receiver and downlink precoder that takes channel estimation errors into account. The proposed uplink receiver and downlink precoder are robust to channel state information inaccuracy, and thus, can guarantee a certain transmission performance. Monte-Carlo simulations illustrate the significant performance improvement in net spectral efficiency offered by the proposed CPR approach.
