“第三极文化”视野下的中国电影美学

第三极文化理论对中国电影美学建设具有启示意义,在第三极理论的视野下,对中国电影的美学渊源、美学精神、美学内涵进行重新观照,有助于解释或解答许多困惑性的问题,尤其对中国电影的民族化建设具有重要的启示价值.     

气藏水平井连续携液理论与实验

在气藏水平井中随着生产管柱倾斜角度的变化，井筒内液体的重力作用会发生改变，从而引起气液两相流型的变化。以产气为主的气井井筒内液体主要以液膜、液滴的形式出现，由此出现了液滴模型与液膜模型两种解释积液的理论。从这两种携液理论出发，考虑生产管柱倾斜角度的影响，对倾斜管内液滴、液膜进行受力分析，推导出了随管柱倾斜角度变化的连续携液临界流速的计算式，使之适用于水平井连续携液临界流量的计算。设计制作了水平气井连续携液实验装置并进行了实验研究，观测气藏水平井中气水两相运动与流型变化情况并测试其临界携液气量，结果表明，气藏水平井中水平井段的液体以液膜携带为主，但直井段中越接近井口，越以液滴携带为主，液滴模型也能适用于计算气藏水平井的连续携液临界流速。     

基于可信性理论的Mean-CVaR投资组合优化

选取CVaR作为风险度量指标,在可信性理论的基础上构建Mean-CVaR投资组合模型,采用Markov过程预测作为模糊变量的预期投资收益率,并设计基于模糊模拟和遗传算法的混合智能算法以求解;选取上证50成份股2013—2014年的日度历史交易数据,将该模型应用到中国证券市场,结果发现该投资组合模型与中国证券市场的环境具有一定的适应性,能够为投资者的投资决策提供依据。     

小说的影像阐释及其意义解读

小说的影像阐释是当代影视剧生产的重要源泉,在视觉文化主导的今天,小说的影像阐释不仅使小说进入文字阅读和视听感知结合的“共读”时代,而且为影像作品提供了丰富的内容和形式。同时,小说的影像阐释已经对当代作家的小说书写、小说生成方式及小说传播形态产生了意义深远的影响。     

Prediction of future failures times based on Type-I hybrid censored samples of random sample sizes

In this article, we consider the prediction of future failure times based on Type-I hybrid censored samples. Point predictors and prediction intervals using different procedures are discussed for a general model. The exponential and Rayleigh distributions are used as illustrative examples to show the most simplified forms of the so obtained predictors as well as prediction intervals. Intensive simulation study and a real life dataset are presented to illustrate our findings and results.     

Application of hybrid framework to facilitate lean six sigma implementation: a manufacturing company case experience

This study aims to propose a hybrid framework for lean six sigma (LSS) based on the prioritisation of barriers and solution approaches, to facilitate hassles free applications for handling the challenges of wastes reduction and quality improvement. The study identifies 27 LSS barriers and 22 solution approaches through literature review and utilises feedback from industry experts. For framework, study uses fuzzy AHP-PROMETHEE to prioritise LSS barriers and solution approaches. Incorporating fuzzy sets in analytical hierarchy process (AHP) ensures the optimality of barrier weights. Whereas, preference ranking organisation method for enrichment of evaluations (PROMETHEE) helps in pairwise comparisons of solution approaches with respect to each LSS barrier, facilitating fair judgements. This research guides regarding the development of framework and checks its suitability and robustness through case application of an Indian manufacturing organisation. Authors expect that researchers and practitioners will find study useful for LSS and multi criteria decision making(MCDM) domains.     

Whatever Happened to Drama? A Configurational–Comparative Analysis of Genre Trajectory in American Cinema, 1946–2013

Although usually conceived of and studied as individual types, genres are frequently combined in practice. This research examines how genres are combined in popular American films, and how the popularity of particular combinations changed between 1946 and 2013. Distinguishing between “contextual genres” (which identify a film's subject matter) and “affective genres” (which identify a film's intent), we find marked differences between the postwar and blockbuster eras of the Hollywood film industry. The blockbuster era exhibits less generic diversity than the earlier postwar era. Furthermore, the popular postwar‐era films dealt with serious subjects and were set in realistic settings. The blockbuster era replaced these with intense, nonrealistic films. We also find that the relationship between contextual and affective genres changes within industry eras, with affective genres dominating at the beginning of new periods and the popularity of contextual genres growing as the period progresses.     

Documentarians,fair use,and free expression: changes in copyright attitudes and actions with access to best practices

This study, based on a survey of 489 documentary filmmakers, is a case study in copyright policy in and through practice. It assesses the changes in documentary production practice around clearance of copyrighted material since the creation of the Documentary Filmmakers' Statement of Best Practices in fair use in 2005. Fair use, an exotic and occasional feature of documentary film in 2004, has become well known and commonly employed. Creative options for filmmakers concerning the use of third-party material have dramatically improved with changes in norms after the issuing of the Statement. Attitudes about fair use are strongly associated with free expression and creative opportunity, and vary with experience. Where filmmakers have changed work because of copyright concerns, they themselves rather than any gatekeeper have made the decision to do so. Where change is associated with fair use, risk is a common concern. Newer filmmakers are more likely to support the use of copyrighted material to make new work, but less likely to know about fair use, and also more likely to have experienced takedowns online. Both education about and experience with fair use appear to have an effect on practice. Filmmakers continue to lack reliable information on the actual risk landscape, and about fair use on digital platforms.     

论中国早期电影的自由精神

中国早期电影突破传统模式、打破封建牢笼,善于吸收西方先进文化中所体现的自由价值取向.从电影的选题、创作、以至宣传发行都是独立自由、勇于创新的.早期电影深受多元文化的影响,直接倡导自由精神,鞭笞落后反动的旧式习俗思潮,这一切为早期中国电影的发展注入了无限活力,对整个社会也产生了深远的影响.     

大数据驱动下的影视文本创作 和生产模式变革

大数据正以其对规律和趋势的分析预测功能,对人们生活和影视内容生产产生日益深刻的影响。数据化思维是贯穿当下影视生产创作的重要思维形态,延承的正是传统数据化思维的基本认知过程。大数据驱动下的互动参与生产模式主要体现在,借助于受众行为数据分析,可以对导演、故事、表演、影像、剪辑和声音等影视元素进行选择,并在此基础上进行生产或再生产。这些将推动影视内容生产在技术和观念上不断变革。
