“Inside” and “Outside” of the Author and the Work—Looking into Lady Chatterley’s Lover  [PDF]
Lizhen Chen
Advances in Literary Study (ALS) , 2018, DOI: 10.4236/als.2018.63011
Concerning D. H. Lawrence and his most controversial work Lady Chatterleys Lover, there are in existence various theories. This paper first makes an introduction of D. H. Lawrence and his work Lady Chatterleys lover, and then tries to scrutinize the author and the work in terms of traditional criticism and psychological criticism. The internal facts (“inside”) and external facts (“outside”) of the author and the characters in the work are elaborated, mainly through traditional approach and psychological approach, hence the conclusion is that Lawrence’s works were deeply interweaved with his complex and full-of-controversy life and that readers ought to attach more importance to the author’s life as well as his work.
The Industrial Relations of Logistics Industry—Based on China’s 2010 Input-Output Table  [PDF]
Jin Zhang, Lizhen Chen
Modern Economy (ME) , 2014, DOI: 10.4236/me.2014.512099

The paper explores the intrinsic link between logistics industry, national economy and three industries by using Chinese input-output table of 2010. It shows that logistics industry has the strongest inquiry and need on secondary industry; next is itself and the last is Agriculture. Second, the influence coefficient of logistics industry is after the second industry radiation ability; its status in national economy is strong and has become the dominant industry of national economic development. Furthermore, the degree of fluctuation for logistics industry is small, and its restriction role and bottleneck effect are obvious for national economy. Moreover, logistics industry is a sector with strong radiation and weak constraints and its promotion effect on national economy is more pronounced than that of national economy on itself.

The Review of SMEs Open Innovation Performance  [PDF]
Jin Zhang, Lizhen Chen
American Journal of Industrial and Business Management (AJIBM) , 2014, DOI: 10.4236/ajibm.2014.412077
Abstract: Open innovation has provided more opportunities and broader space for Small- and Medium- sized Enterprises (SMEs for short) in innovative practices, but also brought new challenges to SMEs. Focusing on the performance of SMEs in open innovation, this paper conducts a literature commentary from several aspects including innovation performance, constraints, impact and strategy of improving open innovation performance of SMEs on the basis of systematic domestic and foreign literature review. The paper also points out the direction for future research.
Ceramide Mediates Ox-LDL-Induced Human Vascular Smooth Muscle Cell Calcification via p38 Mitogen-Activated Protein Kinase Signaling
Lizhen Liao, Qin Zhou, Yan Song, Weikang Wu, Huimin Yu, Sheng Wang, Yanling Chen, Meihong Ye, Lihe Lu
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0082379
Abstract: Vascular calcification is associated with significant cardiovascular morbidity and mortality, and has been demonstrated as an actively regulated process resembling bone formation. Oxidized low density lipoprotein (Ox-LDL) has been identified as a regulatory factor involved in calcification of vascular smooth muscle cells (VSMCs). Additionally, over-expression of recombinant human neutral sphingomyelinase (N-SMase) has been shown to stimulate VSMC apoptosis, which plays an important role in the progression of vascular calcification. The aim of this study is to investigate whether ceramide regulates Ox-LDL-induced calcification of VSMCs via activation of p38 mitogen-activated protein kinase (MAPK) pathway. Ox-LDL increased the activity of N-SMase and the level of ceramide in cultured VSMCs. Calcification and the osteogenic transcription factor, Msx2 mRNA expression were reduced by N-SMase inhibitor, GW4869 in the presence of Ox-LDL. Usage of GW4869 inhibited Ox-LDL-induced apoptosis in VSMCs, an effect which was reversed by C2-ceramide. Additionally, C2-ceramide treatment accelerated VSMC calcification, with a concomitant increase in ALP activity. Furthermore, C2-ceramide treatment enhanced Ox-LDL-induced VSMC calcification. Addition of caspase inhibitor, ZVAD-fmk attenuated Ox-LDL-induced calcification. Both Ox-LDL and C2-ceramide treatment increased the phosphorylation of p38 MAPK. Inhibition of p38 MAPK by SB203580 attenuated Ox-LDL-induced calcification of VSMCs. These data suggest that Ox-LDL activates N-SMase-ceramide signaling pathway, and stimulates phosphorylation of p38 MAPK, leading to apoptosis in VSMCs, which initiates VSMC calcification.
More Efficient VLR Group Signature Based on DTDH Assumption
Lizhen Ma
TELKOMNIKA : Indonesian Journal of Electrical Engineering , 2012, DOI: 10.11591/telkomnika.v10i6.1428
Abstract: In VLR (verifier-local revocation) group signature, only verifiers are involved in the revocation of a member, while signers are not. Thus the VLR group signature schemes are suitable for mobile environments. To meet the requirement of speediness, reducing computation costs and shortening signature length are two requirements at the current research of VLR group signatures. A new VLR group signature is proposed based on q-SDH assumption and DTDH assumption. Compared with the existing VLR group signatures based on DTDH assumption, the proposed scheme not only has the shortest signature size, but also has the lowest computation costs , and can be applicable to mobile environments such as IEEE 802.1x.
Study on Policy Adjustments ---Based on Changing Policy from “Ban” to “Limit Fireworks in Beijing
Lizhen Zhang
Asian Social Science , 2009, DOI: 10.5539/ass.v4n9p113
Abstract: Any policy adjustment has profound reasons, and policy of “ban” on fireworks and firecracker in Beijing changed to “limits” is also a response to specific issue under the concrete space and time. The discussion on the reasons of policy adjustment is helpful to understanding of the influencing factors of policy execution so as to bring the suitable policy into full display and unsuitable policy an end. Beijing city forbade setting off fireworks and firecrackers during1993-2005, while now Beijing lays a limit to set off fireworks and firecracker, which is interact ional result of policy environment, policy itself as well as policy subject and others.
Study on Obstacles to Policy Termination
Lizhen Zhang
Journal of Politics and Law , 2009, DOI: 10.5539/jpl.v2n4p98
Abstract: But the termination of public organizations, policies and programs has usually been neglected by policy researchers. This paper is intended to explore why the ending of policy is so tough that few case is reported in practice. The main reasons for the longevity of government organizations and policies are as follows: intellectual reluctance, institutional permanence, antitermination coalition, legal obstacle, high start-up costs, pressure from public opinion, influence of interest groups, incrementalism at work, dynamic conservatism and so on. In the second part, some general strategies for making the termination option more available are suggested.

Abstract: This paper proves some results on negative gradient dynamics of Morse functions on Hilbert manifolds. It contains the compactness of flow lines, manifold structures of certain compacti- fied moduli spaces, orientation formulas, and CW structures of the underlying manifolds.
On the Associativity of Gluing
Lizhen Qin
Mathematics , 2011,
Abstract: This paper studies the associativity of gluing of trajectories in Morse theory. We show that the associativity of gluing follows from of the existence of compatible manifold with face structures on the compactified moduli spaces. Using our previous work, we obtain the associativity of gluing in certain cases. In particular, associativity holds when the ambient manifold is compact and the vector field is Morse-Smale.
Complete invariant geodesic metrics on outer spaces and Jacobian varieties of tropical curves
Lizhen Ji
Mathematics , 2012,
Abstract: Let $\mathrm{Out}(F_n)$ be the outer automorphism group of the free group $F_n$. It acts properly on the outer space $X_n$ of marked metric graphs, which is a finite-dimensional infinite simplicial complex with some simplicial faces missing. In this paper, we construct complete geodesic metrics and complete piecewise smooth Riemannian metrics on $X_n$ which are invariant under $\mathrm{Out}(F_n)$. One key ingredient is the identification of metric graphs with tropical curves and the use of the tropical Jacobian map from the moduli space of tropical curves to the moduli space of principally polarized tropical abelian varieties.
