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。  相似文献

Research on the effects of mood in organizations tends to focus on the valence dimension of mood (positive vs. negative), overlooking the activation dimension (activated vs. deactivated). We suggest that activation level prompts unethical behavior. Based on the affective infusion model (AIM; Forgas, 1995), we predict that positive activated and negative activated moods facilitate unethical behavior to benefit a teammate, via the mediating mechanism of a creative mindset. We test our full model using an experience sampling method over 2 weeks, in which mood and creative mindset were assessed in the morning and unethical behavior conducted that day was assessed in the evening. We found that activated moods (both positive and negative) were positively related to unethical behavior to benefit a teammate. Further, creative mindset mediated the relationship between positive activated mood and unethical behavior to benefit a teammate. Consistent with AIM's claim that mood should influence decisions more when they are not personally relevant, we found that moral disengagement propensity moderated this indirect effect. In addition, we conducted two experiments to examine further the mood-creative mindset and creative mindset-unethical behavior to benefit a teammate relationship. Our findings affirm that activated versus deactivated moods facilitate a creative mindset, and that a creative mindset encourages unethical behavior to benefit a teammate. Our findings suggest that activation level of mood plays a critical role in unethical behavior.  相似文献

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.  相似文献

处于自我损耗状态时, 个体在意愿上偏好即时利益和目标, 并且会做出许多非理性决策行为。在梳理自我损耗对行为决策的影响基础上, 指出自我损耗降低决策理性的注意机制和执行机制:一方面, 损耗使个体注意力更容易为即时利益所捕获, 进而重视短期利益而忽视长远利益, 即降低个体关注未来的能力; 另一方面, 损耗导致个体缺少计划性和行为实施的执行力, 即降低个体坚守未来的能力。此外, 损耗对决策理性的影响存在个体和情境两个方面的重要边界。未来可结合眼动技术验证损耗降低决策理性的注意机制, 进一步探究潜在边界条件以及寻找助推理性决策的方法。  相似文献

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。  相似文献

The nontechnical ability to identify or match argumentative structure seems to be an important reasoning skill. Instruments that have questions designed to measure this skill include major standardized tests for graduate school admission, for example, the United States-Canadian Law School Admission Test (LSAT), the Graduate Record Examinations (GRE), and the Graduate Management Admission Test (GMAT). Writers and reviewers of such tests need an appropriate foundation for developing such questions – they need a proper representation of phenomenological argumentative structure – for legitimacy, and because these tests affect people's lives. This paper attempts to construct an adequate and appropriate representation of such structure, that is, the logical structure that an argument is perceived to have by mature reasoners, albeit ones who are untrained in logic.  相似文献

结直肠癌诊断模式的若干思考   总被引:1,自引:1,他引:0  
结直肠癌是常见的消化道恶性肿瘤,然而在临床上得到诊断时大多已经到了中晚期,错过了最佳的治疗时机。近年来,随着基因相关技术及生物信息技术的迅猛发展,结直肠癌诊断方法得到不断改进,但早期诊断仍不尽如人意。因此现有的诊断模式值得我们去深思,从哲学意义上探索更为完善的诊断模式。  相似文献

用现代医学模式看心血管疾病合并抑郁症的诊疗   总被引:3,自引:1,他引:2  
随着社会进步,生活节奏日益加快,抑郁症及抑郁情绪已经悄无声息地蔓延开来,心血管疾病已成为城乡居民的第一位死因,分别为心理、生理疾病,从传统医学模式的角度看两者互不相干,但从生理-心理-社会的现代医学模式理解以及各种研究表明它们其实有着密切的联系。  相似文献

Policies and position statements regarding decision-making for extremely premature babies exist in many countries and are often directive, focusing on parental choice and expected outcomes. These recommendations often state survival and handicap as reasons for optional intervention. The fact that such outcome statistics would not justify such approaches in other populations suggests that some other powerful factors are at work. The value of neonatal intensive care has been scrutinized far more than intensive care for older patients and suggests that neonatal care is held to a higher standard of justification. The relative value placed on the life of newborns, in particular the preterm, is less than expected by any objective medical data or any prevailing moral frameworks about the value of individual lives. Why do we feel less obligated to treat the premature baby? Do we put newborns in a special and lesser moral category? We explore this question from a legal and ethical perspective and offer several hypotheses pertaining to personhood, reproductive choices, “precious children,” and probable evolutionary and anthropological factors.  相似文献
