Trustworthy media news content retrieval from web using truth content discovery algorithm

Nowadays, the internet plays a major role in online information retrieval. As, we are well aware the web provides information related all the fields like national, lifestyle, movies, shopping, spirituality, sports, entertainment and much more. One cannot assume that the web retrieved information is believable or trustworthy due to multiple answers to the same query. The paper aims to study many research articles which are related to truth information discovery. However, the paper found that there is no proper research to find trustworthiness of news content which is extracted from multiple information sources with minimum misclassification error and retrieval time. To alleviate these issues, the truth content discovery algorithm is proposed to produce trustworthy information with minimal time along with multiple domain news information. The system provides reliable information from a various source of news provider with minimum classification error. The proposed method ranked the news content index based on query matches from extracted information. It minimizes the query retrieval time and classification error. Based on the experimental evaluation, proposed TCD + J48 algorithm produced the best result compared to existing approaches. It minimizes reduces 7.54 ms the query retrieval time (QRT), 5% Error rate (ER) and 0.98 and Mean Normalized Absolute Distance (MNAD).     

身份交换对多身份追踪表现的影响

本研究探讨了身份交换对多身份追踪表现的影响。实验1和实验2分别考察了全部报告法和部分报告法下身份交换对多身份追踪表现的具体影响。结果均发现, 身份交换对身份−位置绑定干扰程度越大, 位置追踪和身份识别容量也均越低, 但位置容量始终高于身份容量, 并且这些特性在不同追踪负荷上相同。此外, 部分报告法比全部报告法更具有容量测量优势。实验3则进一步从听觉通道上控制了语音复述对当前任务的干扰, 所得结果仍支持实验1和实验2。这表明, 身份交换对多身份追踪的干扰机制是身份−位置绑定机制受到损害, 而非语音复述的作用。     

Attentional resources in visual tracking through occlusion: the high-beams effect

A considerable amount of research has uncovered heuristics that the visual system employs to keep track of objects through periods of occlusion. Relatively little work, by comparison, has investigated the online resources that support this processing. We explored how attention is distributed when featurally identical objects become occluded during multiple object tracking. During tracking, observers had to detect small probes that appeared sporadically on targets, distracters, occluders, or empty space. Probe detection rates for these categories were taken as indexes of the distribution of attention throughout the display and revealed two novel effects. First, probe detection on an occluder’s surface was better when either a target or distractor was currently occluded in that location, compared to when no object was behind that occluder. Thus even occluded (and therefore invisible) objects recruit object-based attention. Second, and more surprising, probe detection for both targets and distractors was always better when they were occluded, compared to when they were visible. This new attentional high-beams effect indicates that the ability to track through occlusion, though seemingly effortless, in fact requires the active allocation of special attentional resources.     

Learning from explaining: does it matter if mom is listening?

The goal of the current study was to examine whether explaining to another person improves learning and transfer. In the study, 4- and 5-year-olds (N=54) solved multiple classification problems, received accuracy feedback, and were prompted to explain the correct solutions to their moms, to explain the correct solutions to themselves, or to repeat the solutions. Generating explanations (to selves or moms) improved problem-solving accuracy at posttest, and explaining to mom led to the greatest problem-solving transfer. The study indicates that explanation prompts can facilitate transfer in children as young as 5 years and reveals that it matters if mom is listening.     

线索呈现位置对概率类别学习的影响

当前概率类别学习中主要存在多系统和单系统两种观点之争, 而持不同观点的研究者在其实验中分别采用了不同的线索位置呈现方式, 因此本研究采用经典的天气预测任务通过操纵线索位置的呈现方式来进一步探讨其对概率类别学习的影响。本研究包括2个实验：实验1考察所有线索位置固定和随机对概率类别学习系统的影响; 实验2通过单线索模式下线索位置固定考察概率类别学习的策略。结果发现, 当所有线索的呈现位置固定时, 概率类别学习是外显学习; 而当所有线索的呈现位置随机时, 概率类别学习是内隐学习; 而当只在线索单独出现时固定其位置, 概率类别学习仍是内隐学习。结果表明, 线索位置的不同呈现方式会影响概率类别学习中外显和内隐学习系统的竞争, 研究支持了多系统观点, 且概率类别学习的主要策略可能是多线索策略而不是单模式策略。     

Multiple Kernel Contraction

This paper focuses on the extension of AGM that allows change for a belief base by a set of sentences instead of a single sentence. In [FH94], Fuhrmann and Hansson presented an axiomatic for Multiple Contraction and a construction based on the AGM Partial Meet Contraction. We propose for their model another way to construct functions: Multiple Kernel Contraction, that is a modification of Kernel Contraction, proposed by Hansson [Han94] to construct classical AGM contractions and belief base contractions. This construction works out the unsolved problem pointed out by Hansson in [Han99, pp. 369]. This revised version was published online in August 2006 with corrections to the Cover Date.     

心理测验中的趋中回归与超常分数重现概率

研究了心理测验中的趋中回归及其性质,超常分数重现概率与真分数的分布、测验信度、超常分数界值的关系。结果表明,信度越低,趋中回归越大;超常分数界值越高,趋中回归越大。在正态分布下,超常分数重现概率与信度是指数关系;超常分数重现概率与界值是直线关系。初步讨论了如何在心理学研究中避免和减少趋中回归的误导。     

On psychoanalytic figures as transference objects

One of the tasks that analysts and therapists face at a certain stage in their career is how to develop a way of psychoanalytic thinking and practising of their own. To do this involves modifying or overcoming the transferences established during their training or early career. These transferences are to one's teachers or training analyst, investing them with authority and infallibility, and to received theory, which is treated as though it were dogma. The need to free oneself from such transferences has been discussed in the literature. There is, however, another kind of transference that the developing therapist also needs to resolve, which has received little attention. This is the transference made on to a key figure in the psychoanalytic tradition. Such a psychoanalytic figure will be seen as the originator of or embodiment of those theoretical ideas to which one becomes attached, and/or as standing behind one's training analyst or seminal teachers who become a representative of that figure. The value of an investigation of one's relationship to a psychoanalytic figure is that it is an excellent medium for revealing one's transference, as the figure in question is not a real person but only exists through his/her writings. The body of the paper consists of an extended example of such an analysis, that of my own transference on to the figure of Winnicott. In this example I illustrate how my evaluation of Winnicott's ideas changed from seeing them as providing answers to all my clinical questions to no longer satisfying me in some areas of my work. This change in my relationship to Winnicott's theory went hand in hand with a modification in my transference on to the figure of Winnicott, from seeing him as endowed with authority and goodness to an appreciation of him as a still sustaining figure but now with limits and flaws. In the final part of the paper several questions arising out of my analysis are posed. Can the pull of writing such an account in terms of dramatic rupture rather than gradual and partial change be avoided? Should my account be regarded purely as a form of self‐analysis or does it have anything to say about Winnicott himself and his theory? And do some psychoanalytic figures attract more intense or sticky transferences than others?
