自媒体环境下表达自由的规制

自媒体以其无中心化、平民化、交互性、匿名性,改变着传统媒体的环境和传播方式,掀起了媒介领域的一场革命。自媒体表达自由既使公民获得个体的自我实现,也极大拓展了公民行使政治性权利的空间。但超越边界的表达自由滋生了诸如传播色情内容、扰乱社会秩序、侵犯个人隐私及知识产权等问题,因此对自媒体传播内容及表达自由的规制迫在眉睫。在规制过程中不能超过必要限度,而限度意识则意味着自媒体表达自由的规制要坚持一定的原则。     

自媒体的道德特征

自媒体的迅速发展给人们的道德世界带来了重大变化,它增强了人们道德的自主性,展示了人自身的自主性价值、自我抉择性以及独立人格的精神属性,自主性乃是自媒体时代道德的根本属性。但是,自媒体在自身发展的同时也加剧了公共性道德的危机,由于缺乏对他人和社会的关怀,自媒体加深了人性的弱点在公共话语空间中的表现。要解决公共性道德危机,当然需要他律性法律的介入,但自律性的道德依然不可缺失。     

性自主权、道德与法律干预——以“南京换偶案”为例

换偶案作为一个聚讼纷争的特殊案例,在道德、价值多元化的时代,引发了人们对换偶的权利,道德性及合法性的多向度的思考。在将换偶纳入性自主权的思考维度中,性的自治自决也必须与责任担当与人性尊严相协调;在道德、法律的聚光灯下,即使是坚守自由主义的中立原则,对换偶之类的性行为方式,也只是主张一定的道德宽容而非道德虚无。当然,法律在有限度涉入这一高度争议的性领域时,应有坚实的干预理由并保持适度的界限。     

论道德法律化的合理性及限度——以“常回家看看”入法为视角

道德和法律在调整范围和价值追求等方面有一定的重叠。在我国现阶段道德滑坡、约束能力不断弱化的背景下,提高公民道德水平,重塑社会道德体系便显得尤为迫切和重要。道德法律化作为其中一个有效途径,有其必要性和可行性。修订后的《老年人权益保障法》中"常回家看看"入法便是道德法律化的一个例证。然而无论道德或是法律的调整作用都不是万能的,道德法律化也有其局限性,"常回家看看"入法也存在一定的操作困境;需要在此基础上,界定道德法律化的合理限度,并对提高"常回家看看"法律的可操作性和执行性提出合理化的规制措施。     

试论诚实信用原则的内涵与外延

针对人们在认识和适用诚实信用原则时对该原则内涵的模糊性与外延的不确定性的不易把握状况入手,在内涵方面,提出了"法律规制善意说",即在法律规则范围内所从事的善意行为才是诚实信用原则所许可的;在外延方面,从该原则外延判断标准入手,提出了"二标准说",即主观诚信标准和客观诚信标准,从而使人们对诚实信用原则的内涵与外延有了一个新的认识。     

以法理学角度分析网络暴力

随着社会经济的迅猛发展,互联网与人们日常生活的联系越来越密切,发挥的作用越来越大,与之同时也带来一些问题,比如网络暴力。网络暴力是一种危害程度较高、影响较恶劣的暴力形式,网络暴力表现为一些网民打着言论自由的幌子,突破言论自由的边界,利用网络发表不实言论恶意攻击他人的行为。这种不实言论侵犯了他人合法权益,甚至破坏了社会的稳定。网络暴力行为已经突破了现代法治精神中的言论自由,因此我们需要对此从道德和法律的角度进行规制,尤其是以法律的手段进行规制。不仅需要现行实体法从司法执法的角度规制,更需要从法学理论层面对法的创立与实施进行指引,以此更好地保障个人、他人、社会之间利益的平衡。     

从“杨乃武与小白菜案”透视晚清法律文化

1840年的鸦片战争,叩开了大清王朝的大门。自此以后,与其说清王朝走向了衰败,不如说从更广的意义上,中国朝着法治迈进了一大步。西方的法律文化随着晚清的媒体传入中国,与自古以来根植于人们内心的法律观念激烈碰撞、相互交融,孕育出的"新生儿"随着媒体被广为人知。晚清时代的文化浸透在生活中的点点滴滴,而媒体则透过生活展现了法律文化的方方面面。     

规制“婚外情”问题的路径选择——法律困境与道德理性

新时期,研究规制"婚外情"问题的路径选择,对于解决"婚外情"问题,构建和谐家庭,有着重要意义。一方面,法律在规制"婚外情"问题上陷于现实困境;另一方面,道德在约束"婚外情"问题上凸显现实理性。加强婚姻领域道德建设,是规制"婚外情"问题的理性路径。     

自媒体时代下的高校学生管理工作分析

功利主义能取代集体主义吗

市场经济的共性决定了功利伦理对人们的道德生活具有重大影响,但不能据此认为功利主义可以作为我国社会的道德原则.坚持集体主义道德原则是由我国社会主义市场经济的个性决定的.它不仅为社会主义市场经济的健康发展所必需,而且是保护个人正当利益的有效途径.     

Characterization of Ordovician carbonate reservoirs, southeastern Saskatchewan, Canada

The discovery of the prolific Ordovician Red River reservoirs in 1995 in southeastern Saskatchewan was the catalyst for extensive exploration activity which resulted in the discovery of more than 15 new Red River pools. The best yields of Red River production to date have been from dolomite reservoirs. Understanding the processes of dolomitization is, therefore, crucial for the prediction of the connectivity, spatial distribution and heterogeneity of dolomite reservoirs.The Red River reservoirs in the Midale area consist of 3～4 thin dolomitized zones, with a total thickness of about 20 m, which occur at the top of the Yeoman Formation. Two types of replacement dolomite were recognized in the Red River reservoir: dolomitized burrow infills and dolomitized host matrix. The spatial distribution of dolomite suggests that burrowing organisms played an important role in facilitating the fluid flow in the backfilled sediments. This resulted in penecontemporaneous dolomitization of burrow infills by normal seawater. The dolomite in the host matrix is interpreted as having occurred at shallow burial by evaporitic seawater during precipitation of Lake Almar anhydrite that immediately overlies the Yeoman Formation. However, the low δ18O values of dolomited burrow infills (-5.9‰～ -7.8‰, PDB) and matrix dolomites (-6.6‰～ -8.1‰, avg. -7.4‰ PDB) compared to the estimated values for the late Ordovician marine dolomite could be attributed to modification and alteration of dolomite at higher temperatures during deeper burial, which could also be responsible for its 87Sr/86Sr ratios (0.7084～0.7088) that are higher than suggested for the late Ordovician seawaters (0.7078～0.7080). The trace amounts of saddle dolomite cement in the Red River carbonates are probably related to "cannibalization" of earlier replacement dolomite during the chemical compaction.     

An Index mechanism for multi-scale view in spatial databases

There are numerous geometric objects stored in the spatial databases. An importance function in a spatial database is that users can browse the geometric objects as a map efficiently. Thus the spatial database should display the geometric objects users concern about swiftly onto the display window. This process includes two operations:retrieve data from database and then draw them onto screen. Accordingly, to improve the efficiency, we should try to reduce time of both retrieving object and displaying them. The former can be achieved with the aid of spatial index such as R-tree, the latter require to simplify the objects. Simplification means that objects are shown with sufficient but not with unnecessary detail which depend on the scale of browse. So the major problem is how to retrieve data at different detail level efficiently. This paper introduces the implementation of a multi-scale index in the spatial database SISP (Spatial Information Shared Platform) which is generalized from R-tree. The difference between the generalization and the R-tree lies on two facets: One is that every node and geometric object in the generalization is assigned with a importance value which denote the importance of them, and every vertex in the objects are assigned with a importance value,too. The importance value can be use to decide which data should be retrieve from disk in a query. The other difference is that geometric objects in the generalization are divided into one or more sub-blocks, and vertexes are total ordered by their importance value. With the help of the generalized R-tree, one can easily retrieve data at different detail levels.Some experiments are performed on real-life data to evaluate the performance of solutions that separately use normal spatial index and multi-scale spatial index. The results show that the solution using multi-scale index in SISP is satisfying.

海南岛地体及其毗邻陆缘晚中生代—新生代古地磁研究和构造演化

本文叙述了对海南岛及其毗邻大陆边缘白垩纪到第四纪地层岩石进行古地磁研究的全部工作过程。通过分析岩石中剩余磁矢量的磁偏角及磁倾角的变化,提出海南岛白垩纪以来经历的构造演化模式如下:早期伴随顺时针旋转而向南迁移,后期伴随逆时针转动并向北运移。联系该地区及邻区的地质、地球物理资料,对海南岛上述的构造地体运动提出以下认识:北部湾内早期有一拉张作用,主要是该作用使湾内地壳显著伸长减薄,形成北部湾盆地。从而导致了海南岛的早期构造运动,而海南岛后期的构造运动则主要是受南海海底扩张的影响。海南地体运动规律的阐明对于了解北部湾油气盆地的形成演化有重要的理论和实际意义。

An on-line scaling method for improving scalability of a database cluster

The explosive growth of the Internet and database applications has driven database to be more scalable and available, and able to support on-line scaling without interrupting service. To support more client's queries without downtime and degrading the response time, more nodes have to be scaled up while the database is running. This paper presents the overview of scalable and available database that satisfies the above characteristics. And we propose a novel on-line scaling method. Our method improves the existing on-line scaling method for fast response time and higher throughputs. Our proposed method reduces unnecessary network use, i.e. , we decrease the number of data copy by reusing the backup data. Also, our on-line scaling operation can be processed parallel by selecting adequate nodes as new node. Our performance study shows that our method results in significant reduction in data copy time.     

An improved R-tree based on childnode''s probability

R-Tree is a good structure for spatial searching. But in this indexing structure,either the sequence of nodes in the same level or sequence of traveling these nodes when queries are made is random. Since the possibility that the object appears in different MBR which have the same parents node is different, if we make the subnode who has the most possibility be traveled first, the time cost will be decreased in most of the cases. In some case, the possibility of a point belong to a rectangle will shows direct proportion with the size of the rectangle. But this conclusion is based on an assumption that the objects are symmetrically distributing in the area and this assumption is not always coming into existence. Now we found a more direct parameter to scale the possibility and made a little change on the structure of R-tree, to increase the possibility of founding the satisfying answer in the front sub trees. We names this structure probability based arranged R-tree (PBAR-tree).     

Integrating GIS Web services based on mediating architecture

The geographic information service is enabled by the advancements in general Web service technology and the focused efforts of the OGC in defining XML-based Web GIS service. Based on these models, this paper addresses the issue of services chaining,the process of combining or pipelining results from several interoperable GIS Web Services to create a customized solution. This paper presents a mediated chaining architecture in which a specific service takes responsibility for performing the process that describes a service chain. We designed the Spatial Information Process Language (SIPL) for dynamic modeling and describing the service chain, also a prototype of the Spatial Information Process Execution Engine (SIPEE) is implemented for executing processes written in SIPL. Discussion of measures to improve the functionality and performance of such system will be included.
