论高校学生党建工作中的网格化管理模式

网格化管理是根据属地管理、地理布局、现状管理等原则,将管辖地域划分成若干网格状的单元,并对每一网格实施动态、全方位的管理,它是一种数字化的管理模式,将其运用在高校党员队伍建设中,有助于管理者在第一时间里掌握管理对象的第一手资料,以便及时发现问题,解决问题。在具体操作中,要注意三点:一是确保数据的真实性;二是确保数据更新的及时性;三是确保网格成员的平等性。     

潜北地区潜四段烃类包裹体与原油地球化学特征

利用有机包裹体的提取及色谱-质谱分析技术,对潜北地区潜四段储层中的烃类包裹体进行详细分析,结果表明:潜四段油藏普遍具有成熟和高成熟两期油气充注,仅少数油藏为一期高成熟油充注。潜二段末期较大范围的构造运动,为成熟油大规模二次运移聚集提供了有利条件,荆河镇组末期则是潜江组高成熟原油大规模运移聚集成藏的主要时期。     

基于BP网络虚拟企业敏捷性评价

高敏捷性是虚拟企业适应不断变化的市场必备的素质,如何对它进行准确评价是虚拟企业运行中的重要问题,针对此问题先对虚拟企业及其盟员敏捷性之间的关系进行了分析,然后归纳总结出了可行的敏捷性评价指标,提出在已知虚拟企业盟员敏捷性的基础上用BP神经网络来计算虚拟企业的敏捷性,最后通过仿真试验测试了该方法的可行性。     

新形势下深入推进“学生党员责任岗”建设的探索

在新形势下，如何加强学生党员的教育管理，使大学生党员发挥先锋模范作用、体现其先进性，是高校各级党组织一直在思考的问题。本文对如何建立和完善大学生党员责任岗制度，提出了具体的措施。     

元坝气田须四段断裂带裂缝预测

为明确元坝气田须四段断裂带裂缝分布,依据岩心、薄片、测井等资料分析了裂缝特征和断裂作用、岩层厚度、岩石性质对岩石破裂的影响,确定了岩层厚度、断层分布、断裂效应及岩性分布等因素的权重因子,并采用“多参数非线性综合加权”法对裂缝进行了预测.结果表明:岩性和岩层厚度是岩石破裂的基础,岩层越薄裂缝越发育;断层是岩石破裂的直接因素,断裂效应集中区断层规模越大及距离断层越近裂缝越发育.     

子洲地区山2气藏地震预测技术

子洲—清涧地区是继榆林地区之后的又一个以山2砂岩储层为勘探目标的新的目标区，如何利用地震预测技术寻找有利砂岩展布规律，是一项技术性较强的研究工作，经过多年的努力，研究出一套比较成熟的山2气藏预测技术系列，高分辨率处理技术、反演技术、含气性检测技术联合研究预测储层，取得了比较好的应用效果．为子洲—清涧地区山2气田的发现起到了重要作用。     

川中川南过渡带嘉二段成藏条件及主控因素

研究区嘉二段构造起伏平缓,断裂及裂缝相对较小,碳酸盐岩和蒸发岩发育,基本属于(半)局限-蒸发台地相,部分属于开阔台地相.台内滩、台内雏滩、(半)局限台地泻湖和(半)局限台地潮坪等亚相影响储层的形成和发育;蒸发台地泻湖、蒸发台地潮坪和局限台地泻湖等亚相控制盖层的分布.通过对烃源条件、储盖组合、圈闭类型、天然气运聚特征和保存条件等方面的详细分析,认为川中川南过渡带嘉二气藏成藏条件优越,具有形成中型气藏的潜力,其中天然气的近源垂向运聚和理想的保存条件,是形成嘉二气藏的重要保障.有利的沉积亚相、建设性成岩作用、背斜构造、烃源断层和硬石膏岩层是该气藏的成藏主控因素.烃源断层和硬石膏岩层的分布,为油气聚集层位及有利成藏区块的确定提供了重要信息.     

Determinants of successful virtual communities: Contributions from system characteristics and social factors

Although there is growing interest in virtual communities, few studies have examined them from an integrated viewpoint including technical and social perspectives. By expanding on DeLone and McLean’s IS success model, the author constructed a model of the impact of system characteristics (e.g., information and system quality) and social factors (e.g., trust and social usefulness) in implementing successful virtual communities. Data collected from 198 community members provided support for the model. Results showed that both member satisfaction and a sense of belonging were determinants of member loyalty in the community. Additionally, information and system quality were found to affect member satisfaction, while trust influenced the members’ sense of belonging to the community. Finally, the findings provided understanding of the factors that measured virtual community success. Implications of my study are discussed.     

Determinants of success for online communities: an empirical study

Although online communities can significantly facilitate collaboration among Internet users, the determinants of success of online communities have seldom been studied empirically. Using the updated DeLone and McLean information systems success model as a theoretical framework, this study proposes a research model to examine the determinants for successful use of online communities. Based on a survey of 165 community members, this study uses structural equation modelling (SEM) approach to investigate the research model. The analytical results strongly support the appropriateness of the research model in identifying the determinants of success of online communities. The analytical results also showed that system quality, information quality and service quality had a significant effect on member loyalty through user satisfaction and behavioural intention to use the online community. Finally, this study discusses the implications of these findings and offer directions for future research.
