有组织犯罪概念之界定

天津市政法管理干部学院学报 2002年第2期18卷 42-45页

作者：袁力中国人民公安大学研究生部北京100038

目前,国内外仍没有一个得到普遍接受与公认的有组织犯罪概念。本文从犯罪学和刑法学的不同角度对有组织犯罪概念进行了分析,并论证了国际上尽早规定一个统一的有组织犯罪概念的必要性和可能性。

Cogeneration of electricity and liquid fuel can achieve higher efficiencies than electricity generation alone in Integrated Gasification Combined Cycle (IGCC), and cogeneration systems are also expected to mitigate CO2 emissions. A proposed methanol-electricity cogeneration system was analyzed in this paper using exergy method to evaluate the specified system. A simple cogeneration scheme and a complicated scheme including the shift reaction and CO2 removal were compared. The results show that the complicated scheme consumes more energy, but has a higher methanol synthesis ratio with partial capture of *** those methanol and electricity cogeneration systems, the CO2 mitigation is not merely an additional process that consumes energy and reduces the overall efficiency, but is integrated into the methanol production.

当前偷渡案件中犯罪手段呈现隐蔽化、组织化、智能化的特点,偷渡组织已发展成为国际化犯罪集团,一般的侦查对策难以充分收集到深层次犯罪情报、证据及线索,难以对偷渡行为实施有效控制和打击。通过对我国南北边境沿海地区偷渡案件的调研发现,偷渡案件侦查工作中存在案件经营时间长、成本高、偷渡案组织者定罪有法律争议、取证难、缺乏国际警务合作等问题,针对这些偷渡案件侦查中的问题,需要以情报为主线,从秘密力量、内线侦查、技术侦查、阵地控制、国际警务合作等几个方面强化偷渡案件侦查对策。

Entry word 'geo' means the relations between the earty surface layer and its *** existence and development of humanity are in progress on certain spatial places and duringspecific time series. It is not only philosophic truth but also objective reality. people always define theinteraction between human society and natural world as man-land relationship. which contains eitherthe tangible habitat of human being or the intangible bearing got involved in it. so far asgeoenvironment is an enlarged geographic surroundings, from macroscopic cosmos to elementaryparticle without exception. The purpose of thes paper is to expound the relationship for human beingwith its factors affiliated on global surface. The authors firmly believe that humankind possesses threeoverlapping levels of environment on earth enclosure including physical (natural), economic(artificial) and humanistic (ideological) spheres.

Acta Pharmacologica sinica 2005年第6期26卷 705-713页

Aim: To examine if cadherins are expressed constitutively in human bone marrow stromal cells （hBMsC） and investigate the regulation of cadherin expression by various osteotropic hormones and local factors. Methods: Cadherin expression was examined in first passaged （secondary） hBMsC as well as in the conditionally-immortalized human osteoprogenitor cell line （hOP-7）. Using a monoclonal antibody （MoAb C-1821） to a cytoplasmic domain common to all known cadherins （pan-cadherin MoAb）, cadherins were immunolocalized in first passaged hBMsC as well as in hOP-7 cells. In addition, intense immunostaining for cadherin expression was associated with alkaline phosphatase （ALP） in nodules formed in the high density cultures of hOP-7 cells. Human E-cadherin （HECD） was specifically detected by Western blotting in extracts of untreated hBMsC using an anti-HECD MoAb 004FD. Results: Differential regulation of cadherin expression by various osteotropic hormones and local factors （parathyroid hormone, dexamethasone, estradiol, prostaglandin E2, basic fibroblast growth factor, and tumor necrosis factor-） was also observed. In addition, blocking cadherins with the MoAb C-1821 increased basal ALP activity and had an additive effect on 1, 25（OH）2D3.induced ALP activity. Conclusion: Cadherins are expressed in human osteoprogenitor cells and are involved in the osteogenic differentiation. The differential modulation of cadherin expression by osteotropic agents indicates that these agents may regulate osteoprogenitor cells through different cadherins and these cadherins may play different roles.

This study examines the evolution of fiscal relations between the central state and local governments in china since the founding of the people's Republic The emphasis is placed on the changing arrangement for the central state's collection of taxes and allocation of capital among provinces The central local relation has experienced constant reorganization since 1949, but the tax division scheme introduced in the early 1990s represents the most significant change Prior to the 1990s, the central local fiscal relation was shaped by a highly centralized administrative and economic system without rational and scientific design for revenue collection and expenditure The financial responsibility system established after the reforms contributed to regional economic development during the first decade of reforms, but it was a temporary and transitional arrangement that does not meet the requirement of rational resources arrangement according to free market forces The implementation of the tax division scheme has stopped the decline of the ratio of fiscal revenue to gross domestic product, raised the percentage of central revenue in total national income, and strengthened the central function for macro economic control The mechanism for tax refund under the tax division scheme required further improvements several proposals are made in this study: 1) tax classification should be adjusted according to administration; 2) a scientific and standardized system for regional transfer payment should be developed; and 3. the power for tax legislation should be delineated according to the rational division of administration between the central and local government

稳定的社会秩序是一个社会健全程度的标志。因此 ,如何获得社会秩序的问题历来受到人们的关注。在所有谋求社会秩序的方式中 ,通过政府而实现的社会公平和正义是最为可靠的。一个社会只有实现了公平和正义 ,才能够消解一切根本性的社会冲突诱因 ,实现稳定的社会秩序供给。但是 ,在现实中 ,腐败问题尤其是政府中存在的一些严重的腐败问题成了当前一切社会冲突的诱因。所以 ,应当从反腐败着手 ,在实现政府道德化的过程中 ,实现整个社会道德水平的全面提升。

BACKGROUND: Hilar cholangiocarcinoma is associated with low resectability and poor survival. The aim of this study was to evaluate the roles of matrix metalloproteinases- 2 (MMP-2 ) and its tissue inhibitor of metalloproteinase-2 (TIMP-2) in tumor invasion or as a prognostic factor in patients with human hilar cholangiocarcinoma. METHODs: The expressions of MMP-2 and TIMP-2 were investigated in patients. Paraffinized tissue sections ob- tained from 50 patients with human hilar cholangiocarcino- ma were analysed. The expressions of MMP-2 and TIMP-2 were examined immunohistochemically. Image analysis with image-pro plus analysis software was used to semi- quantitatively determine the ratio of MMP-2 to TIMP-2. REsULTs: The expression levels of MMP-2 and TIMP-2 were strongly associated with tumor hepatic invasion in pa- tients with hilar cholangiocarcinoma. significant diffe- rences in the ratio of MMP-2 to TIMP-2 between some pathologic factors were observed in patients with hilar cholangiocarcinoma. CONCLUsIONs: MMP-2 plays an essential role in tumor invasion and metastasis,while TIMP-2 is shown to strongly inhibit cancer invasion and metastasis. The ratio of MMP-2 to TIMP-2 may be a prognostic indicator for patients with hilar cholangiocarcinoma.
