双重介质油藏数值模拟并行算法研究

裂缝型碳酸盐岩油藏非均质性极强，数值模拟运算时间长，迫切需要一种切实可行的解决方法。介绍了区域分解法在数值模拟中的应用方法，提供了油藏数值模拟串行算法并行化的一般策略与方法。基于已开发的双重介质油藏数值模拟串行算法及建立的Windows平台PC集群网络并行计算环境，利用消息传递界面（MPI库）实现了并行过程中所有消息的传递功能。通过对国内某实际碳酸盐岩油田的模拟表明，并行后的算法是成功的，2个PC加速比高达1.86，4个PC达到3.46，8个PC达到6.89。通过模拟还发现，并行数值模拟时，存在最佳的子区域规模和数目。该算法解决了大规模碳酸盐岩油藏数值模拟时间长的问题，具有实际的应用价值。     

Moderator Assistant: A Natural Language Generation-Based Intervention to Support Mental Health via Social Media

As online mental health support groups become increasingly popular, they require more support from volunteers and trained moderators who help their users through “interventions” (i.e., responding to questions and providing support). We present a system that supports such human interventions using Natural Language Generation (NLG) techniques. The system generates draft responses aimed at reducing moderators’ workload, and improving their efficacy. NLG and human interventions were compared through the ratings of 35 psychology interns. The NLG-based system was capable of generating messages that are grammatically correct with clear language. The system needs improvement, however, moderators can already use it as draft responses.     

论广告产业生态系统理论的构建

尽管人类社会与自然界有着天然的不同，但是人类社会是自然界长期发展的结果，人类社会就必然带有自然界的某些特征与规律。广告传播是人类信息社会最重要的传播现象之一。随着社会经济的快速发展，广告传播呈规模化、系统化方向发展的趋势，广告信息传播主体之间的关系也越来越复杂，呈现出类似自然生物之间的一种生态关系。本文试图在普通生态学的理论基础上构建广告生态系统理论。     

Revisiting the digital divide in Canada: the impact of demographic factors on access to the internet,level of online activity,and social networking site usage

The present study relies on the 2010 Canadian Internet Use Survey to investigate differences in people's access to the internet and level of online activity. The study not only revisits the digital divide in the Canadian context, but also expands current investigations by including an analysis of how demographic factors affect social networking site (SNS) adoption. The findings demonstrate that access to the internet reflects existing inequalities in society with income, education, rural/urban, immigration status, and age all affecting adoption patterns. Furthermore, the results show that inequality in access to the internet is now being mimicked in the level of online activity of internet users. More recent immigrants to Canada have lower rates of internet access; however, recent immigrants who are online have significantly higher levels of online activity than Canadian born residents and earlier immigrants. Additionally, women perform fewer activities online than men. People's use of SNSs differs in terms of education, gender, and age. Women were significantly more likely to use SNSs than men. Interestingly, high school graduates had the lowest percentage of adoption compared to all other education categories. Current students were by far the group that utilized SNSs the most. Canadian born, recent, and early immigrants all showed similar adoption rates of SNSs. Age is a strong predictor of SNS usage, with young people relying heavily on SNSs in comparison to those aged 55+. The findings demonstrate that the digital divide not only persists, but has expanded to include inequality in the level of online activity and SNS usage.     

大众媒体的经济分析

大众传播研究不能忽视大众媒体所有权和控制权的经济含义.这不仅仅是一个“谁拥有媒体”的问题.媒体产业的市场结构、企业行为、绩效以及公共政策之间的关系是构成媒体所有权的关键所在.     

媒介批评视角下的肖洛霍夫形象

中国媒体对肖洛霍夫形象的构建,与中苏(俄)两国的政治、经济与文化关系密不可分。当两国关系处于和平友好阶段时,中国媒体对肖洛霍夫的态度就显得很亲善,甚至达到狂热崇拜的地步;一旦两国关系恶化,中国媒体对肖洛霍夫及其作品采取憎恶态度;只有两国关系正常化之后,媒介批评才归于理性与公正。     

未成年人心理健康的影响因素分析

未成年人的心理健康一直是众多学者研究的重要课题,特别是在社会转型时期,有关未成年人的心理问题预防的研究显得尤为重要,要有效的预防未成年人的心理问题,首先应弄清哪些因素影响心理健康,学术界已揭示了影响未成年人心理健康的部分因素,本文以实证的方法来进一步从社区、学校和媒体等方面揭示影响未成年人心理健康的因素,为未成年人心理素质提高政策的制定提供现实依据.     

论媒体技术与互联网艺术的互动

20世纪末以来，互联网艺术在与媒体技术的互动中蓬勃发展。媒体技术的发展水平决定了互联网艺术的分期、形态与特征，互联网艺术则通过创造工具与作品、前最与背最、本体与社区联合体推动了媒体技术的社会应用。二者良性互动有利于形成新型的网络文化。     

Young People’s Perception Of Being Safe – Globally &; Locally

Giddens explores, in Modernity and Self-Identity, our preoccupation with risks in modern social life and the disparity between perceived risks and actual prevalence of life-threatening dangers [Giddens, A.: 1991, Modern and Self-Identity. Self and Society in Late Modern Age (Polity Press, Cambridge), p. 115]. Modern technologies have made global information accessible around the world; real time news communiqués about unfolding situations are displayed directly into the home environment through television and the internet. Global issues and local events intermix, blurring worldwide issues and threats with local realities. This research explored the everyday life of young people in two Australian rural communities, their community affiliation, sense of belonging and feeling safe in the local rural community. The research was exploratory in nature and based on a survey of 751 young people aged between 14 and 21 years, all being students at local secondary high schools. Feeling safe was of concern for both female and male young people: females indicated a higher tolerance towards strangers and cultural diversity, but at the same time, they felt less safe in the local community. These findings are discussed in relation to a 1989–1990 study of 13- to 21-year-old urban Australian and Swedish young people. The study explored young people’s experiences of scary events in mass media, in their home environment and among themselves. The findings signify the need for a holistic approach to identify social indicators to describe the grounds for young people feeling unsafe and the need to take into consideration local community circumstances, the global milieu and conflicts as portrayed in news, documentary and entertainment mass media.
