多目标追踪任务中不同运动方式非目标的抑制机制

采用多目标追踪范式结合点探测技术的方法, 考察视觉系统对不同运动方式(静止和规则运动)非目标的抑制机制。实验一将部分非目标设置为静止, 考察静止非目标的抑制机制; 实验二将部分非目标设置为规则运动, 以提高任务难度, 考察规则运动非目标的抑制机制。结果发现: (1) 实验一中静止非目标受到抑制, 抑制量与运动非目标没有差异; (2) 实验二中规则运动非目标受到抑制, 抑制量显著小于随机运动非目标; (3)综合两实验发现, 随着任务难度的提高, 只有随机运动非目标的抑制量显著增加, 而静止非目标与规则运动非目标的抑制量差异不显著。最后, 就视觉系统对不同运动方式非目标的抑制机制进行了讨论。     

Effect of Perceived Politics and Perceived Support on Bullying and Emotional Exhaustion: The Moderating Role of Type A Personality

Recognizing that bullying can occur in varying degrees of severity, the current study suggest the importance of individual traits in individual perceptions of being targets of bullying and ensuing emotional exhaustion. The present study extends the work environment hypothesis and trait activation theory by a joint investigation of the mediating role of (a) workplace bullying in linking perceived organization politics and perceived organization support with emotional exhaustion and (b) the moderating role of Type A behavioral pattern in influencing the mediation. Using a field sample of 262 employees working in different organizations of Pakistan, this study tested a moderated mediation model. Results were consistent with the hypothesized model, in that workplace bullying mediated the relationship of perceived organization politics and perceived organization support with emotional exhaustion. Type A behavior moderated the perceived politics—bullying, perceived support–bullying, and bullying—emotional exhaustion relationships. The mediation of bullying varied with levels of Type A behavior in these relationships.     

The grandfather

The author, grandson of C.G. Jung, architect and historian, resident in the Küsnacht house, offers perspectives on the role of the grandfather. C.G. had a difficult relationship with his father but felt a strong rapport with his grandfather Karl Gustav Jung, even though he died before C.G.'s birth. Andreas notes that there were many parallels in the lives of the two men; C.G.'s memories and the touching personal diary left behind by Karl Gustav will be discussed. Many of Jung's other ancestors will be described from his own personal angle. The paper also encompasses C.G.'s spiritual forerunners and finally the dead, our common nameless ancestors.     

大学生自尊与父母教养方式的相关研究

目的:通过问卷调查了解当代大学生的自尊水平及其父母教养方式,并分析两者之间的关系,为父母教育子女提供有效建议。方法:采用分层随机抽样的方法,运用自尊量表(SES)和父母教养方式评价量表(EMBU)对长江大学320名大学生进行调查。结果:1.大学生自尊与情感温暖方式呈显著正相关,与惩罚严厉、过分干涉保护、拒绝否认呈显著负相关,与偏爱被试无显著相关;2.高自尊大学生与低自尊大学生在父亲和母亲的情感温暖、惩罚严厉、拒绝否认上存在显著差异,在父亲的过度保护方面存在显著差异;3.父母教养方式受城乡环境等因素影响。结论:父母应当采取积极的教养方式教育孩子,塑造孩子的自尊。

安乐死论纲

就发展中国式安乐死提出了１８条纲领性意见。指出安乐死是一种社会文明,需要进行学科的、理论的、法制的、伦理的建设,超越传统上升到新的时代高度。就安乐死的定义、本质、目的、性质、权利、分型、对象等基本问题提出了不同于国外的独立见解。对于安乐死的立法、法制管理的体制和程序,以及医学伦理、生命伦理要服从社会伦理,树立新的安乐死伦理观提出了具体建议。     

Effects of instructional constraints on human fixed-interval performance

Several groups of human subjects were exposed to a variety of experimental conditions involving a fixed-interval 27-second schedule of reinforcement in compound with instructions to constrain in the number of responses within the interreinforcement interval and/or the duration of the experimental session. One group was further exposed to a contingency involving the placement of responses within the IRI. A diversity of patterns of performance was observed, including those typically associated with animal subjects exposed to FI schedules. Generally, the imposition of instructions to minimize session duration reduced post-reinforcement pausing and increased overall reinforcement density from those levels obtained with only instructions to expend a given number of responses per reinforcer. The results are seen to underscore the sensitivity of human fixed-interval performance and the contribution of extra-experimental contingencies.     

图式与句式教学:一个转折复句的教学实验

本研究根据图式理论设计转折复句的教学实验。实验对象是54个小学五年级的学生。研究发现：实验组无论在转折复句的辨认、改正和写作的表现．都明显地优于控制组。其中以改正能力的差异最明显,而且辨认、改正和写作能力的相关系数也很高。     

Brain tumor detection using fusion of hand crafted and deep learning features

The perilous disease in the worldwide now a days is brain tumor. Tumor affects the brain by damaging healthy tissues or intensifying intra cranial pressure. Hence, rapid growth in tumor cells may lead to death. Therefore, early brain tumor diagnosis is a more momentous task that can save patient from adverse effects. In the proposed work, the Grab cut method is applied for accurate segmentation of actual lesion symptoms while Transfer learning model visual geometry group (VGG-19) is fine-tuned to acquire the features which are then concatenated with hand crafted (shape and texture) features through serial based method. These features are optimized through entropy for accurate and fast classification and fused vector is supplied to classifiers. The presented model is tested on top medical image computing and computer-assisted intervention (MICCAI) challenge databases including multimodal brain tumor segmentation (BRATS) 2015, 2016, and 2017 respectively. The testing results with dice similarity coefficient (DSC) achieve 0.99 on BRATS 2015, 1.00 on BRATS 2015 and 0.99 on BRATS 2017 respectively.     

基于同义关联的句子错误记忆：发展性逆转现象及句式效应

以汉语把字句和被字句为材料,采用学习-再认方式,考察基于同义关联的句子错误记忆及其发展性逆转现象和句式效应。实验1结果发现高二和初二校正后的关键诱饵句错误再认率显著高于小学五年级,把字关键诱饵句校正后的错误再认率显著高于被字句,表明基于同义关联的句子错误记忆存在发展性逆转现象和句式效应。实验2结果发现三个年级关键诱饵句与无关句的错误再认率差异均不显著,表明去除同义关联后,句子错误记忆现象被抑制。结果表明,同义关联能诱发句子错误记忆,且句子错误记忆存在发展性逆转现象和句式效应。
