绘画的性格

风格多样的绘画艺术作品向我们展示了其丰富的性格魅力,绘画性格的表象特征揭示和体现着时代的气息与艺术家自身的性格与内涵的构成。其具有不可复制性与唯一性。我们只有以真诚的心去对待画面和艺术,不断提高自身的理论素养,细心体味生活,才能更深入、更贴近艺术的真实和内心自我的真实。     

基于用户行为的社交网络人格特质识别方法

社交网络已成为人们获取和发布信息的一个重要平台,也是黑客发起网络诈骗的主要场地。大多数黑客在发起网络诈骗之前,首先会判别目标用户的主要人格特点,然后根据主要人格特点制定与其接触的策略。因此,面向社交网络用户的人格特质识别方法的研究对提高用户识别社交网络诈骗能力具有重要意义。提出基于用户的人格特质识别方法。通过构建面向社交网络的人格特质词典提取用户发表或转发文本信息中能反映用户主要人格特质类型的观测值,采用5个具有不同参数值的隐半马尔可夫模型刻画用户在社交网络上发表或转发文本信息的行为过程。在人格特质识别阶段,通过计算每个用户在发表或转发文本信息过程中产生的观测序列相对于模型的平均对数似然概率,以识别用户所属的人格特质类型。在采集的新浪微博数据集上进行实验,结果表明,当假正率为10%时,该方法的总真正率为93.18%,能准确识别用户的人格特质类型。     

Wetting of Rough Walls

Quenched geometric disorder of a wall delimiting a spectator phase can have dramatic effects on the nature of critical wetting transitions. We consider self-affine walls in 2D with roughness exponent _W. Transfer matrix results for directed interfacial models with short-range interactions suggest that wetting turns first-order as soon as _W exceeds ₀, the anisotropy index of interface fluctuations in the bulk. Discontinuous interface depinning is best identified by a peculiar two-peak structure in the statistical distributions of wall–interface contacts obtained by sampling over disorder. On the other hand, for _W<₀ wetting remains continuous, most plausibly in the same universality class as with flat walls. This occurs both with ordered (₀ = 1/2) and with bond-disordered (₀ = 2/3) bulk. A precise location of the thresholds at _W = ₀ can be argued on the basis of an analysis of different terms in the interfacial free energy. This analysis elucidates the peculiar role played by the intrinsic interfacial roughness and suggests extensions of the results to 3D and to long-range substrate forces.     

论楼盘标志设计的创意与表现

楼盘标志是房地产视觉营销的核心要素,标志的优劣直接关系整体品牌视觉形象的水平。本文主要对楼盘标志设计的创意与表现的方法及原则进行探讨。文章首先指出深刻理解楼盘的市场营销策略是进行创意的基础,设计的目标就是把楼盘的"卖点"以极富创意的视觉表现方式呈现给目标消费者。其次提出标志创意要在共性基础上善于发现和表现个性。最后本文从造型、色彩、编排等方面对标志的视觉表现提出了一些设计原则和需注意的细节问题。     

论唐代服装的特点

唐代是中国封建社会的辉煌时期,政治和经济的雄厚基础,以及文化和艺术的繁荣,深刻影响了作为其载体的服装的风貌。唐代的服装不仅雍容华美,其进步的服装文化更是影响深远,它的开放性、容纳精神和突出个性的特质不仅为后世留下了美轮美奂的唐代传统服装,还对启示后世的服装审美和意识有深远影响。     

Musculoskeletal symptoms among mobile hand-held device users and their relationship to device use: A preliminary study in a Canadian university population

The study aims were, in a population of university students, staff, and faculty (n = 140), to: 1) determine the distribution of seven measures of mobile device use; 2) determine the distribution of musculoskeletal symptoms of the upper extremity, upper back and neck; and 3) assess the relationship between device use and symptoms. 137 of 140 participants (98%) reported using a mobile device. Most participants (84%) reported pain in at least one body part. Right hand pain was most common at the base of the thumb. Significant associations found included time spent internet browsing and pain in the base of the right thumb (odds ratio 2.21, 95% confidence interval 1.02–4.78), and total time spent using a mobile device and pain in the right shoulder (2.55, 1.25–5.21) and neck (2.72, 1.24–5.96). Although this research is preliminary, the observed associations, together with the rising use of these devices, raise concern for heavy users.     

Automatic eye fixations identification based on analysis of variance and covariance

Eye movement is the simplest and repetitive movement that enables humans to interact with the environment. The common daily activities, such as reading a book or watching television, involve this natural activity, which consists of rapidly shifting our gaze from one region to another. In clinical application, the identification of the main components of eye movement during visual exploration, such as fixations and saccades, is the objective of the analysis of eye movements: however, in patients affected by motor control disorder the identification of fixation is not banal. This work presents a new fixation identification algorithm based on the analysis of variance and covariance: the main idea was to use bivariate statistical analysis to compare variance over x and y to identify fixation. We describe the new algorithm, and we compare it with the common fixations algorithm based on dispersion. To demonstrate the performance of our approach, we tested the algorithm in a group of healthy subjects and patients affected by motor control disorder.     

What's social about social psychology? Where's the person in personality research?

Content analyses of research published in the 1982 volumes of the Journal of Personality and Social Psychology indicate that social psychologists have largely failed to study subjects drawn from meaningfully defined social groups, to consider social structural variables, to study genuine social interaction, to observe social influences on psychological functioning, or to ask Ss about social issues. It is maintained that with few exceptions, personality researchers have failed to study groups other than college students, to use biographical materials or personal documents, to devise appropriate experimental treatments, to study persons over time, or even to retain the individual as a unit of analysis. Currently, the 2 fields of social and personality psychological research appear to be linked mainly by their deficiencies and appear to have little content worth sharing. Reexamination of each field's traditions and priorities is urgently needed. (22 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)
