什么决定着用户对产品的完整体验?

用户体验是以用户与产品的交互为基础而形成的用户对产品的完整感受。研究其决定因素可以有针对性地提高用户体验。早期研究表明, 可用性、美感和情感都有重要影响但皆不是唯一的决定因素, 近年来的研究重点关注于多因素整合理论及其模型的建立。在总结实效/享乐结构理论、用户-企业-产品双层结构理论和四种过程模型以提取用户体验影响因素的基础上, 提出目前研究的突破点可在三方面, 一是深入探讨各因素的作用, 二是揭示社会型产品用户体验的形成规律, 三是揭示用户体验随时间变化的规律。     

Informant Discrepancies in Assessing Child Dysfunction Relate to Dysfunction Within Mother-Child Interactions

We examined whether mother-child discrepancies in perceived child behavior problems relate to dysfunctional interactions between mother and child and stress in the mother. Participants included 239 children (6–16 years old; 58 girls, 181 boys) referred for oppositional, aggressive, and antisocial behavior, and their mothers. Mother-child discrepancies in perceived child behavior problems were related to mother-child conflict. Moreover, maternal stress mediated this relationship. The findings suggest that discrepancies among mother and child evaluations of child functioning are not merely reflections of different perspectives or artifacts of the assessment process, but can form components of conceptual models that can be developed and tested to examine the interrelations among critical domains of child, parent, and family functioning.     

Mereological nihilism: quantum atomism and the impossibility of material constitution

Mereological nihilism is the philosophical position that there are no items that have parts. If there are no items with parts then the only items that exist are partless fundamental particles, such as the true atoms (also called philosophical atoms) theorized to exist by some ancient philosophers, some contemporary physicists, and some contemporary philosophers. With several novel arguments I show that mereological nihilism is the correct theory of reality. I will also discuss strong similarities that mereological nihilism has with empirical results in quantum physics. And I will discuss how mereological nihilism vindicates a few other theories, such as a very specific theory of philosophical atomism, which I will call quantum abstract atomism. I will show that mereological nihilism also is an interpretation of quantum mechanics that avoids the problems of other interpretations, such as the widely known, metaphysically generated, quantum paradoxes of quantum physics, which ironically are typically accepted as facts about reality. I will also show why it is very surprising that mereological nihilism is not a widely held theory, and not the premier theory in philosophy.     

THE ROLE OF CONSCIOUSNESS AS MEANING MAKER IN SCIENCE, CULTURE, AND RELIGION

Two hundred years ago, Friedrich Schleiermacher took critical issue with Immanuel Kant's intellectual notion of intuition as applied to human nature (Wellmon 2006). He found it necessary to modify—"hermeneutically," as he said—Kant's notion of anthropology by enabling it to include as human the new and strange human tribes Captain Cook found in the Pacific South Seas. A similar hermeneutic move is necessary if physics is to include the local contextual empirical syntheses of relativity and quantum physics. In this hermeneutical revision the synthesis is formed around the notion of a Hilbert Vector Space as the universal grammar of physics, adding to it the dynamic of the Schrödinger equation, and representing empirical "observables" by projection operators that map the subspaces of definite measurable values. Among the set of observable projection operators, some pairs share the same subspace, commute with one another, and share a common laboratory setting. Other pairs do not share this property and are described as being mutually complementary. Complementary symmetries introduce into the discursive language of physics the commonsense notion of contextuality. The new synthesis, proposed by Eugene Wigner, John von Neumann, and (in his own way) Paul Dirac, brought physics into the community of common language and established it as a work of general human achievement. ¹     

科学隐喻的方法论意义

The essential significance of scientific metaphor lies in applying the general metaphorical theory to specific interpretations and elaborations of scientific theories to form a methodology of scientific explanation. It is a contextual grasp of objective reality. A given metaphorical context and its grasp of the essence of reality can only be valid when the context is continually restructured. Taking the context as a whole, the methodological characteristic of scientific metaphor lies in the unity of understanding and choice, experience and concepts, semantic structures and metaphorical domains, rationality and irrationality. As a form of thinking based on reasons, scientific metaphor plays an important role in invention, representation, explanation, evaluation, and communication.

在多媒体语境条件下词类对儿童英语词汇学习效果的影响

该研究考察了多媒体动画片语境条件下,词类对儿童英语词汇学习效果的影响,结果发现:(1)儿童对名词和形容词的再认成绩显著优于代词;(2)就独立回忆测验而言,名词的成绩显著高于代词,形容词的成绩处于代词和名词之间,但与二者的差异均不显著;(3)就情境回忆测验而言,名词与形容词的成绩差异不显著,二者均显著高于代词;(4)名词与形容词的情境回忆测验成绩均显著高于独立回忆测验成绩,但代词的独立回忆与情境回忆测验成绩差异不显著。总体而言,儿童对名词和形容词的学习效果好于代词,表明词类会对儿童英语词汇学习效果产生影响。     

来源记忆提取的情境线索效应

探索当存在多维来源信息时,对一个维度的来源信息的再现是否会促进对另一个维度的来源记忆的提取,即出现情境线索效应。以汉字词语作为项目刺激,以背景颜色作为情境线索,通过两个实验分别考察对呈现位置和背景形状的提取是否会出现情境线索效应。结果发现：只在对背景形状的提取中出现了情境线索效应,并且线索负载越高,效应越小。该结果表明对来源记忆提取时,来源信息间的高可结合性是引发情境线索效应的重要因素。     

Speech acts and arguments

Speech act theory seems to provide a promising avenue for the analysis of the functional organization of argument. The theory, however, might be taken to suggest that arguments are a homogenous class of speech act with a specifiable illocutionary force and a single set of felicity conditions. This suggestion confuses the analysis of the meaning of speech act verbs with the analysis of the pragmatic structure of actual language use. Suggesting that arguments are conveyed through a homogeneous class of linguistic action overlooks the way in which the context of activity and the form of expression organize the argumentative functions performed in using language. An alternative speech act analysis would treat folk terminology as a heuristic entry point into the development of a technical analysis of the myriad argumentative functions and structures to be found in natural language use. This would lead to a thorough-going pragmatic analysis of the rational and functional design of speech acts in argumentation.     

Effectiveness of a consultation intervention to promote tobacco control policies in Northwest Indian tribes: Integrating experimental evaluation and service delivery

A quasi-experimental replication of an intervention for promoting tobacco control policies in Northwest Indian tribes is described and the process of intervention including issues of collaboration among research institutions and Indian organizations is discussed. The policy intervention was evaluated using a pretest-posttest design wherein 20 tribes that had served as wait-list controls now received the intervention. The intervention comprised a tribal representative attending a kickoff orientation; follow-up visits to the tribes; distribution of tobacco policy workbooks; and phone call consultations. Policy status and stringency were assessed by means of telephone interviews with two key contacts per tribe, and by a count of enacted policies. There were significant pre-post changes in the primary outcome measure, a composite summary score of tobacco policy stringency, and changes were also reflected in enacted policies. The intervention effects observed were similar to those found in the prior randomized trial and suggest a robust, disseminable intervention. Much of the success achieved was attributed to the role of an Indian organization in planning the project and implementing the intervention and evaluation protocols.     

题材个体化和问题重述两策略的效果研究

探讨题材个体化和问题重述作为两种解题策略在解决加、减法应用题中的有效性,采用了４种策略类型×３种数学能力水平×２种问题题材×２种题材情境与解题操作关系的四因素混合设计。结论如下：学生基本上能够独立进行题材个体化和问题重述;在本实验条件下,水平高的学生,运用不同策略没有差异;水平中等的学生运用双策略、水平低的学生运用双策略以及题材个体化策略均产生了积极效果;题材个体化策略对于解决不熟悉题材的应用题将产生积极效果,运用以上两策略解决问题情境与解题操作相矛盾的问题没有帮助。除了应用题陈述图式以外,本实验证明还存在着应用题结构图式;可把题材个体化和问题重述作为解题策略教给学生运用。
