为有源头活水来--浅谈融媒时代的影视改编新趋势

近几年,媒介融合已成为传媒业界的新趋势。在此环境下,影视改编从取材于传统文学向网络文学、网络游戏等领域扩展。以网络为代表的新媒体,不仅扩大了影视剧观众的范围,也增强了影视剧的影响力。     

内地、香港语文教科书的性别意识形态比较

教科书隐含着特定的性别意识形态,研究选择内地北师大版与香港新亚洲版小学语文教科书为文本,运用频度统计技术,从选文作者、课文主角、课文人名、插图人物、职业角色五个维度量化分析,认为两套教科书使用的是男性话语,隐含着男性文化或者说是父权意识形态,而且这种倾向香港比大陆更为突出。

电视对彝族村落社会流动的影响——基于布里莫村的民族志调研

运用参与观察、问卷调查、个人访谈、焦点组访谈等研究方法,对彝族村落的媒介消费状况,电视对村民社会流动的影响等问题进行调研。研究发现,彝族村落的媒介消费呈现出"非立体化"和"单一化"的态势;电视对其社会流动产生了重要影响,但这种影响是"隐性"的,具体表现为:在水平流动中,对村民由农村流向城市具有诱惑作用;在垂直流动和代际流动中,对村民上升流动的决策形成产生了潜移默化的影响。     

白藜芦醇联合野生型p53质粒诱导非小细胞肺癌H1299细胞凋亡

目的实验以非小细胞肺癌H1299细胞(简称H1299细胞)为研究对象,主要探讨白藜芦醇联合野生型p53质粒对H1299细胞凋亡作用的影响以及进一步探讨其作用机制。方法在H1299细胞中导入野生型p53质粒,加入不同浓度的白藜芦醇,通过MTT法确定白藜芦醇联合野生型p53质粒的最佳作用浓度,并检测白藜芦醇联合野生型p53质粒对细胞增殖的影响;光镜下观察细胞形态学的变化;流式细胞术检测白藜芦醇联合野生型p53质粒对H1299细胞凋亡率的影响;RT-PCR实验方法检测细胞凋亡相关基因Bcl-2、Bax、Caspase3、Caspase9的表达水平。结果白藜芦醇联合野生型p53质粒能明显抑制H1299细胞的增殖,诱导H1299细胞凋亡,明显抑制Bcl-2基因的表达水平,促进Bax、caspase3、caspase9基因的表达水平。结论白藜芦醇联合野生型p53质粒能够明显抑制H1299细胞的增殖,可能通过促凋亡基因Bax、凋亡蛋白酶Caspase3,Cas?pase9的表达,抑制抑凋亡基因Bcl-2的表达,从而激活细胞中线粒体介导的凋亡通路,诱导H1299细胞凋亡。     

Strategic interactions in public R&D across European countries: A spatial econometric analysis

The paper adds to the existing literature on the determinants of government spending in Research and Development (R&D) by considering the role of strategic interactions among countries as one of the possible competing explanations, within a spatial econometric framework. We account for several factors affecting national levels of public R&D spending, including (i) the international context – i.e. Lisbon strategy; (ii) country characteristics – level of private R&D, GDP, trade openness and the National System of Innovation; (iii) countries’ similarities in relation to (a) trade and economic size and (b) sectoral specialization. The analysis is carried out on 14 European countries. First, we find that factors traditionally affecting the level of public R&D expenditure, such as the scale of the national economy, trade openness, sectoral specialization and private R&D, significantly influence the level of public R&D in European countries between 1994 and 2006. Interestingly, the introduction of the Lisbon strategy does not seem to have affected changes in the levels of public R&D spending. Second, by using different weight matrices, we confirm the existence of strategic interactions in relation to R&D spending among European countries with similar economic, international trade and sectoral structure characteristics, though not geographically close.     

(International) R&D collaboration and SMEs: The effectiveness of targeted public R&D support schemes

This study analyses the impact and effectiveness of targeted public support for R&D investment at the firm level. We test whether the policy design aiming at incentivizing (international) collaboration and R&D in SMEs achieves input as well as output additionality. Our results show that the targeted public subsidies trigger R&D spending, especially so in internationally collaborating SMEs. We further evaluate the different impact of privately financed and publicly induced R&D investment on innovation performance. The results confirm that the publicly induced R&D is productive as it translates into marketable product innovations. While both types of R&D investments trigger significant output effects, the effect of policy-induced R&D investment on sales from market novelties is highest for international collaborators as well as for SMEs.     

Financial information management for university departments,using open-source software

This paper presents a model to analyse the different outcomes generated by the application of Task-Technology Fit (TTF) theory to economic and financial information management in university departments. This model extends that proposed by Goodhue (1995), in two ways: (i) a key role is played by the manager in designing the technology and in performing the task in question. Both of these aspects can be modified, depending on the evaluation made of a series of characteristics (or dimensions) inherent to the model. (ii) The free dissemination of the source code of the application not only allows the transfer of knowledge, but also creates virtual communities which, through collaborative work and the exchange of experiences, can achieve a better fit of the technology to the task at hand. This model has been introduced in several departments at the University of Granada (Spain), and evaluated in terms of the results obtained at both individual and group levels. This evaluation was conducted by means of in-depth interviews with departmental managers.
