Effects of Collocational Congruency,Frequency and L2 Proficiency on the Processing of English Adjective-Noun Collocations

The present study investigates the effects of congruency and frequency on adjective-noun collocational processing for Chinese learners of English at two proficiency levels based on the data obtained in an online acceptability judgment task.The subject pool of this research included 60 English majors studying at a university in China;30 were selected as a higher-proficiency group and 30 as a lower-proficiency group according to their Vocabulary Levels Test(Schmitt et al.,2001)scores and their self-reported proficiency in English.The experimental materials were programmed to E-prime 2.0 and included six types of collocations:(1)15 high-frequency congruent collocations,(2)15 low-frequency congruent collocations,(3)15 high-frequency incongruent collocations,(4)15 low-frequency incongruent collocations,(5)15 Chinese-only items,and(6)75 unrelated items for baseline data.The collected response times(RTs)and accuracy rates data were statistically analyzed by the use of an ANOVA test and pairwise comparisons through SPSS 16.0 software.The results revealed that:(1)the adjective-noun collocational processing of Chinese English learners is influenced by collocational frequency,congruency and L2 proficiency;(2)the processing time is affected by the interaction of congruency and frequency;and(3)the interactive effect of L2 proficiency in conjunction with congruency and frequency also influences the processing quality.

Counting the Unit Solutions of Certain Quartic Diagonal Congruence Modulo n

Given a positive integer n and the residue class ring Z_(n)=Z/nZ,we set Z_(n)^(x)to be the group of units in Z_(n),i.e.,Z_(n)^(x)={x∈Z_(n):ged(x,n)=1}.Let N_(m)(n)be the number of solutions of x_(1)^(4)+…+x_(m)^(4)≡0(mod n)with x_(1),…,x_(m)∈Z_(n)^(x).In this note,we determine an explicit expression of N_(m)(n).This extends the results of Sun and Yang in 2014.

Medical Image Registration Based on Phase Congruency and Regional Mutual Information

In this paper, a new approach of muhi-modality image registration is represented with not only image intensity, but also features describing image structure. There are two novelties in the proposed method. Firstly, instead of standard mutual information （ MI ） based on joint intensity histogram, regional mutual information （ RMI ） is employed, which allows neighborhood information to be taken into account. Secondly, a new feature images obtained by means of phase congruency are invariants to brightness or contrast changes. By incorporating these features and intensity into RMI, we can combine the aspects of both structural and neighborhood information together, which offers a more robust and a high level of registration accuracy.

The Smell of Success?—The Impact of Perfume-Gender Congruency on Ratings of Attraction and the Halo Effect

Research into the concept of attraction has indicated the existence of olfactory influences that go beyond pheromonal level. Synthetic fragrances have been found to affect not only perception of attraction, but also attribution of beauty-unrelated intrinsic characteristics. The present study aimed to examine the impact of perfume-gender congruency on ratings of attractiveness and any perfume-generated halo effect. Male faces categorized as low, medium and high attractiveness were rated by 36 heterosexual female students across six domains: attractive, reliable, outgoing, intelligent, wealthy and socially competent. Ratings were made in the presence of a female perfume (incongruent condition), male perfume (congruent condition) or a no perfume control condition, with participants randomly allocated to produce three groups of equal size. The results indicated that 1) attractiveness generated a significant halo effect;2) the male perfume did not significantly enhance perception of attractiveness compared to the female perfume;and 3) the gender-congruent fragrance heightened attribution of “halo” characteristics. These results indicate that gender congruent perfume can impact positively on first impressions beyond attractiveness, and are discussed in terms of possible mechanisms and implications.

Left- and Right-Handers May Unintentionally Apply Different Cognitive Strategies in Response to Situational Demands: Study Using the Block-Wise Proportion Congruency Effect

We investigated the effects of handedness on developing latent cognitive response strategies according to situation variables. We used the findings of the block-wise Proportion Congruency (PC) effect in which the proportion of congruent trials in a given block modulates the compatibility effect in its block. The block-wise PC effect cannot be intentionally controlled. A Simon task with three different types of Proportion Congruency (PC) in a given block was used to measure the block-wise PC effects. This task was administered to 24 left-handed and 24 right-handed participants. The reaction time and error rates, consistent with previous studies, demonstrated that the block-wise PC effect was observed in left- and right-handers. Crucially, the block-wise PC effect was more pronounced in left- than right-handers, suggesting that left- and right-handers unintentionally apply different cognitive strategies in response to conflict resolution experiences.

Novel and Self-Consistency Analysis of the QCD Running Coupling α_(s)(Q) in Both the Perturbative and Nonperturbative Domains

The quantum chromodynamics(QCD) coupling αs is the most important parameter for achieving precise QCD predictions. By using the well measured effective coupling α_(s)^(g)1)(Q) defined from the Bjorken sum rules as a basis, we suggest a novel self-consistency way to fix the αs at all scales: The QCD light-front holographic model is adopted for its infrared behavior, and the fixed-order p QCD prediction under the principle of maximum conformality(PMC) is used for its high-energy behavior. Using the PMC scheme-and-scale independent perturbative series,and by transforming it into the one under the physical V scheme, we observe that a precise αs running behavior in both the perturbative and nonperturbative domains with a smooth transition from small to large scales can be achieved.

The Deformation Analysis of the 3D Alignment Control Network Based on the Multiple Congruence Models

In the construction and maintenance of particle accelerators,all the accelerator elements should be installed in the same coordinate system,only in this way could the devices in the actual world be consistent with the design drawings.However,with the occurrence of the movements of the reinforced concrete cover plates at short notice or building deformations in the long term,the control points upon the engineering structure will be displaced,and the fitness between the subnetwork and the global control network may be irresponsible.Therefore,it is necessary to evaluate the deformations of the 3D alignment control network.Different from the extant investigations,in this paper,to characterize the deformations of the control network,all of the congruent models between the points measured in different epochs have been identified,and the congruence model with the most control points is considered as the primary or fundamental model,the remaining models are recognized as the additional ones.Furthermore,the discrepancies between the primary S-transformation parameters and the additional S-transformation parameters can reflect the relative movements of the additional congruence models.Both the iterative GCT method and the iterative combinatorial theory are proposed to detect multiple congruence models in the control network.Considering the actual work of the alignment,it is essential to identify the competitive models in the monitoring network,which can provide us a hint that,even the fitness between the subnetwork and the global control network is good,there are still deformations which may be ignored.The numerical experiments show that the suggested approaches can describe the deformation of the 3D alignment control network roundly.

领导与员工的超连接匹配对工作绩效的影响及其机制

数字技术在企业的创新应用正在重构传统企业管理学理论与方法.工作中片刻不离手机和笔记本等多种设备的“超连接”成为常态.已有研究关注了互联网超连接对个体心理和行为的一系列消极影响,却忽略了数字技术赋能下的领导与员工超连接对工作绩效的潜在积极影响.本文基于平衡理论,连续三个月跟踪调查了343份领导与员工的配对样本,结果发现:领导与员工之间的超连接越匹配,员工自主性越高,工作目标进展越快,工作绩效显著增加.进一步发现,当领导与员工同处于高超连接时,员工的自主性高,工作目标进展和工作绩效最佳;而在“员工低—领导高”的不匹配模式下,员工的自主性和工作进展都低.本文从匹配视角探究领导与员工超连接模式对工作绩效的积极后效,为数字技术赋能组织管理的工作模式提供了更加全面和均衡的分析视角,同时也为实现领导与员工的工作模式匹配、协同推进工作绩效提供实践指导.

设D=2p_(1)⋯p_(s)(1≤s≤4),其中p_(1),⋯,p_(s)是互不相同的奇素数。主要利用奇偶分析、同余、递归序列以及Pell方程解的性质等初等方法,对Pell方程组x^(2)-40y^(2)=1与y^(2)-Dz^(2)=9的公解进行研究。得出当D≠2×7×103时,该方程组仅有平凡解(x,y,z)=(±19,±3,0);当D=2×7×103时,除了平凡解(x,y,z)=(±19,±3,0)外,还有非平凡解(x,y,z)=(±27379,±4329,±114)。研究结果丰富了这类Pell方程组整数解的研究内容。

群体信息对面部表情识别的影响

本研究通过3个实验探讨群体信息对面部表情识别的影响。结果发现:(1)周围面孔的情绪状态影响个体对目标面孔情绪的识别,两者情绪一致时的反应时显著短于不一致时的反应时,且面部表情识别准确性更高。(2)群体信息会调节周围面孔情绪对目标面孔的影响,进而影响面部表情识别。具体而言,群体条件下,个体对目标面部表情的识别受到周围面孔情绪状态的影响,相比周围面孔情绪与目标面孔情绪不一致,两者情绪一致时,即符合个体基于知觉线索建立的群体成员情绪具有一致性的预期,面部表情识别的准确性更高、速度更快;而非群体条件下,个体则不受周围面孔情绪状态的影响。研究结果表明,个体能够基于互动人物之间的社会关系识别面孔情绪,群体存在时,会建立群体成员情绪具有一致性的预期,进而影响面部表情识别。

违反正义的利益是没有价值的——罗尔斯关于正当与善关系的三个命题

在正当与善的关系上,罗尔斯提出三个紧密相关的命题:优先、同余和互补。罗尔斯正义理论以古典效用论为主要批评对象。后者是一种目的论,主张正当是极大化的善。前者是一种道义论,主张正当优先于善,简称优先命题。按照优先命题,正当不以追求最大的善为目的。最大的善,只是人类活动的偶然结果,不是受到正义原则规制的制度和法令的合理目标。罗尔斯也主张正当与善有同余关系,简称同余命题。按照同余命题,正当与善是兼容的,公平正义与理性善好是同余的。罗尔斯还表示,正当与善具有互补关系或相辅相成关系,简称互补命题。罗尔斯从互补关系来解读差别原则,主张合乎正义的善是多多益善的。优先命题是罗尔斯对古典效用论的超越,同余命题是罗尔斯对康德道德哲学的超越,互补命题则为公平与效率的一致性提供了论证,是对伯林价值多元论的超越。学术界一般重视优先命题而忽视另两个命题,误解罗尔斯关于正当与善的关系理论,进而误解整个罗尔斯正义理论。
